Description:
BACKGROUND OF THE INVENTION  
         [0001]    In the recent years, the frequently occurred flood related problems in the nationally metropolitan areas have indicated that the applied sluicing standards are unable to process the huge water volume caused by heavy rainfalls. Flood has even become inevitable in the low-lying regions, especially in the ground-lever stores, the residences and the basements. It usually causes severe life and property damage as well as makes people extremely panic. Without any efficient method, most people use the sand bags as the means to prevent the flood. However, the sand bags can only block the water up to about 30 to 60 centimeters but they functions poorly for flooded water exceeding one meter height because the higher the flood is, the greater the water pressure will be; failing to resist the water pressure, the embankment built by the sand bags might burst. In addition, to handle the used sand bags after the flood is another troublesome issue. Therefore, to use sang bags is not the preferred method for preventing the flood. The best way to solve the problem is to research and develop efficient equipment for replacement.  
         SUMMARY OF THE INVENTION  
         [0002]    An assembled sluice gate for flood-prevention and water-blocking comprises two wall posts, a plurality of sluice gates and a connection plate disposed in an entrance area of a doorframe, wherein the two wall posts respectively and fitly mount with a left and a right grooved boards on a doorframe and with the connected sluice gates; the connection plate is fixed between two sluice gates to form a piece of vertical door wall which is covered by a top cover at the upper aspect thereon. A plurality of tight retaining belts fasten the top cover and a fixed groove at the lower portion of the doorframe thereby enabling the door wall to block the water and resist a huge water pressure so as to prevent the water from flowing into the houses or basements. Furthermore, when not in use, the sluice gates are superposed for storage at a proper and hidden position without occupying the space but allowing the automobiles and motorcycles to freely enter and exit unaffectedly.

         [0036]    [0036]FIG. 13 shows the cross-sectional drawing of the assembled grooved board ( 10 ), wall post ( 40 ) and sluice gate ( 50 ); as indicated, the bottom board ( 42 ) of the wall post ( 40 ) is guided into the dovetail groove ( 13 ) of the grooved board ( 10 ); the convex left frame ( 515 ) of the sluice gat ( 50 ) inserts into the upper groove ( 41 ) of the wall post ( 40 ) for fastening; the protruding tenons ( 45 ) insert into the neck portion ( 516 ); two waterproof pads ( 44 ,  57 ) connect each other in a sealed contact; the convex left frame of one sluice gate ( 50 ) inserts into the concave right frame ( 517 ) of another sluice gate ( 50 ); the protruding tenons ( 518 ) insert into the neck portion ( 516 ); two waterproof pads ( 57 ,  58 ) tightly contact each other. The water permeation is prevented through the disposition of the waterproof pad ( 12 ) inserted between the grooved board ( 10 ) and the wall sides, the waterproof pad ( 43 ) between the grooved board ( 10 ) and the wall post ( 40 ), the waterproof pads ( 44 ,  57 ) between the wall post ( 40 ) and the sluice gate ( 50 ) as well as the waterproof pads ( 57 ,  58 ) between the sluice gates ( 50 ).  
         [0037]    In order to make the sluice gates ( 50 ) cooperate tightly to increase the function of pressure resistance, it is necessary to dispose a connection plate ( 60 ) between two sluice gates ( 50 ). Since the connection plate ( 60 ) is installed after all of the sluice gates ( 50 ) and the fixed groove ( 20 ) are fitly mounted, it is the last plate to fit with the fixed groove ( 20 ). For an easy installation, the connection plate ( 60 ) is not of a concave-convex structure; therefore, as indicated in FIG. 14, it is made of squeezed aluminum and the left frame ( 61 ) thereof is in an L-shape; a waterproof pad ( 62 ) is fixed at the protruding end thereof; the right frame ( 63 ) is a convex frame with a concave opening disposed with a waterproof pad ( 64 ). In addition, two manual-type transverse latches ( 65 ,  66 ) are diagonally disposed on the front and the rear sides of the connection plate ( 60 ).  
         [0038]    For cooperating with the left frame ( 61 ) of the connection plate ( 60 ), the structure of the right frame ( 517 ) of one sluice gate ( 50 ) is changed accordingly. In the structure of a sluice gate ( 50 ′) as indicated in FIG. 15, the structure of a right frame ( 519 ) is of the same L-shape as that of the left frame ( 61 ) of the connection plate ( 60 ); a waterproof pad ( 59 ) is also disposed at the protruding end; latch slots ( 67 ) are disposed diagonally on the front and the rear sides thereof.  
         [0039]    After the connection plate ( 60 ) and the sluice gate ( 50 ′) connect, as indicated in FIG. 16, the left frame ( 61 ) of the connection plate ( 60 ) joins with the right frame ( 519 ) of the sluice gate ( 50 ′) to make two waterproof pads ( 62 ,  59 ) tightly contact each other. The front and rear transverse latches ( 65 ,  66 ) are manually latched into the latch slots ( 67 ) to firmly connect and fasten the connection plate ( 60 ) and the sluice gate ( 50 ′). The convex right frame ( 63 ) of the connection plate ( 60 ) fitly mounts with the concave left frame ( 515 ) of a reversely disposed sluice gate ( 50 ″), as shown in FIGS. 2 and 3. The convex right frame ( 517 ) of the reversely disposed sluice gate ( 50 ″) fitly mounts with the wall post ( 40 ).  
         [0040]    [0040]FIG. 17 shows the pictorial drawing of the doorframe ( 1 ) structure in a regular state; as indicated, the wall post ( 40 ) of the doorframe ( 1 ), the sluice gate ( 50 ) and the connection plate ( 60 ) are dismounted and only the top cover ( 30 ) covers on the fixed groove ( 20 ) as indicated in FIG. 18 also; the reason is that the covered opening of the fixed groove ( 20 ) prevents the foreign objects from falling in. It is hard to store the top cover ( 30 ) if the length thereof is too long; therefore, the most preferable method for storage is to cover the top cover ( 30 ) on the fixed groove ( 20 ). As shown, the top side of the top cover ( 30 ) is not flush with the ground surface; however, in a real situation, the top cover ( 30 ) has to be flush with the ground level to facilitate the entering and exiting automobiles and motorcycles. Another exemplary embodiment is to pave a slope respectively on the front and the rear sides of the fixed groove ( 20 ) to facilitate the entering and exiting automobiles and motorcycles.  
         [0041]    The implementation of the present invention achieves the following functions:  
         [0042]    1. Before the flood, the sluice gates are fast assembled to form a door wall to achieve the function of flood-prevention and water-blocking; when not in use, the sluice gate are divided into a plurality of pieces for convenient transportation; with smaller area size, the present invention is very easy for storage without occupying a considerable space.  
         [0043]    2. During the regular time, the top cover covers on the fixed groove of the doorframe allowing the automobiles and motorcycles to enter and exit safely; for implementing a water-blocking sluice gate, the top cover covers on the door wall and fits with the tight retaining belt to make the door wall a pressure resistant and water-blocking sluice gate.  
         [0044]    3. All of the seams between the doorframe, the wall post, the sluice gate and the connection plate are disposed with the waterproof rubber pad; therefore, they are connected tightly to prevent any water leakage.  
         [0045]    4. All of the structures are molded by drawing alloy aluminum; the surfaces thereof has been treated specially to make it weight lightly, easy for processing, have a lower price and a useful life up to thirty years.  
         [0046]    It is of course to be understood that the embodiment described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
