Title: Inspection device for water storage tank
Inventor: NARITA TAKESHI
IPC: E03B11/00
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To prevent tools from dropping in water and dispense with a draining work and prevent suspension of water supply even when an inspector drops the tools by mistake during inspection works for a ball tap floating on the water level, by fitting a sheet body in between an inspection opening and the water level. SOLUTION: The water volume (water level) in a water receive tank or an elevated water tank which are used for water supply equipment of a large building or the like is detected by a float 3a of a ball tap 3 and the water is supplied to a tank by controlling a valve. That is, when the water level in the tank goes down in accordance with the water consumption, the float 3a gets low. When the float goes down to a specified position, the valve is opened to supply water and when the water level goes up to a specified position, the valve is closed to stop supplying water.  A sheet body 6a is arranged so as to cover the periphery of the ball tap 3 in between the inspection opening 1a of the tank and the water level to receive tools on the sheet body 6a and prevent the tools from submerging in water even when an inspector drops the tools or the like by mistake during the inspection work of the ball tap 3. In this way, cost loss such as water draining or suspension of water supply which have caused by falling of tools can be eliminated by the device.
