Title: Hydraulically propelled inspection platform

Description:
FIELD OF THE INVENTION 
     The present invention relates generally to a hydraulically propelled inspection platform. More specifically, the present invention relates to a hydraulically propelled inspection platform mounted with water engines. 
     BACKGROUND 
     Remote inspection of platforms where gas or vapors are normally present can be challenging. Remote inspection may involve the use of a motorized, mobile platform with sensors. The motor of devices that are used for such inspection tend to be electrical, which may not be compatible with the gas-rich environment to be inspected. 
     Therefore, a need exists for a mobile platform that uses non-electric motor propulsion. It is now recognized that using water turbines can provide a non-electrical manner of locomotion for spark-sensitive environments. 
     SUMMARY OF THE INVENTION 
     The following described technology is made in an effort to provide a hydraulically propelled inspection platform mounted with water engines. 
     To achieve the above aim, the hydraulically propelled inspection platform may include a frame and platform; at least a wheel; and at least a water engine. 
     Pressurized water engines (water turbines) connected to the wheels are mounted on the frame and platform. Hoses (water supply pipe) tied as an umbilical cord deliver the pressurized water to the water turbines. Control valves controlling the water flow allow to control forward direction when both the two water turbines are driven and steering capabilities by increasing or limiting the flow to one or the other water turbine. The frame and platform are designed to carry cameras and other inspection tools like ultrasonic-thickness probes. 
     Advantageous Effects of Invention 
     According to certain embodiments of the present invention, a hydraulically propelled inspection platform is mounted with water engines. The advantage of the present invention using the hydraulically propelled inspection platform may inspect floating roof and floors of storage tanks, floating roof tank pontoons, hydrocarbon, process and storage vessels interior, piping process intern al inspection, inspection of process areas with gas or vapors present.

     DETAILED DESCRIPTION OF THE INVENTION 
     The general inventive concept is described more fully below with reference to the accompanying drawings, in which exemplary embodiments of the present invention are shown. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. The present invention should not be construed as being limited to the embodiments. Accordingly, the drawings and description are to be regarded as illustrative in nature to explain aspects of the present invention and not restrictive. Like reference numerals in the drawings designate like elements throughout the specification, and thus their description have not been repeated. 
       FIG. 1  is a prototype of a hydraulically propelled inspection platform equipped with inspection sensors, e.g., a camera and ultrasonic probe in accordance with an exemplary embodiment of the present invention.  FIG. 2  is a side view of the prototype of the hydraulically propelled inspection platform of  FIG. 1 . 
       FIG. 3  is a top view of a prototype of a hydraulically propelled inspection platform in accordance with another exemplary embodiment of the present invention. 
       FIG. 4  is a side view of the prototype of the hydraulically propelled inspection platform of  FIG. 3 . 
       FIG. 5(A)  is a three dimensional image of a hydraulically propelled inspection platform in accordance with another exemplary embodiment of the present invention.  FIG. 5(B)  is a perspective view of the hydraulically propelled inspection platform of  FIG. 5(A) .  FIG. 6  is a side view of the hydraulically propelled inspection platform of  FIG. 5(B) .

     Referring to the drawings of  FIGS. 5-10 , the depicted hydraulically propelled inspection platform  1  may include one or more wheels  2  and one or more engines  3  (e.g., four wheels and two engines). The two water engines  3  may be designed in a similar manner to water engines used in a pressure-side pool cleaning device. The engines  3  may be mounted on a frame, for example a 80/20 aluminum extruded profile frame. One of the engines  3  may be drivingly connected to the left wheels  2 , and another engine  3  may be drivingly connected to the right wheels  2 , giving a steering capability obtained by turning water pressure on or off from one side or the other. In another variation, one engine  3  may be connected to the front wheels  2  and the other engine  3  may be connected to the back wheels  2  to have forward-backward direction. In more complex configurations, four engines (not shown) may be used to have steering and forward-backward control.

     Referring to the drawings of  FIGS. 9-10 , a hydraulically propelled inspection platform  1  may include a frame and platform  4 , four wheels  2  and two water turbines  3 . Two wheels  2  may be located on one side of the frame and platform  4 , while other two wheels  2  may be located on another side of the frame and platform  4 . The two water turbines  3  may be located on top of the frame and platform  4 . Two gears  5  may be located on the frame and platform  4  between the wheels  2 . Two axles  6  may be located to connect the wheels  2  and the water turbines  3 . Water supply pipe  8  may be connected to the two water turbines  3 .
