Description

Technical Field

[0001] This utility model relates to the field of municipal engineering facilities technology, specifically to a clear water pool that is easy to flush and empty. Background Technology

[0002] Clear water tanks, as an important component of water treatment systems, are used to store purified water from the water plant and regulate the balance between the plant's water production and supply. They are typically located in a lower geographical location within the water plant. When clear water tanks require regular cleaning, equipment inspection and maintenance, or when the raw water or purification process is subject to special contamination, such as chemical leaks or microbial contamination, and testing confirms contamination of the clear water tank, it is essential to empty the tank to ensure the stability and safety of the water supply system.

[0003] The commonly used method for venting is to install a vent pipe at the bottom of the clear water tank, with a vent valve on the vent pipe. Opening the vent valve allows the water to drain into the factory's rainwater pipe system by gravity. However, the clear water tank is located at the lowest point in the factory, and the vent pipe is located at the bottom of the clear water tank, directly draining into the rainwater pipe. This lowers the elevation of the entire rainwater pipe system, causing poor or even no rainwater drainage. After long-term use, the bottom and walls of the clear water tank will accumulate sediment, impurities, algae, and other substances. Venting alone cannot completely remove these deposits from the tank. In this case, it is necessary to manually pull a hose from the water supply points around the clear water tank and descend to the bottom of the tank through the inspection hole for flushing. However, the clear water tank usually has a guide wall inside, and flushing must be done along the guide wall, which causes some trouble for the flushing work. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical problem to be solved by this utility model is to provide a clean water tank that is convenient for rinsing and emptying. Multiple water collection pits are set up inside the tank and connected to each other. The water in the tank is quickly and completely emptied by a submersible sewage pump. The emptying well and the overflow well are built together and use the same outlet to reduce the footprint. At the same time, a rinsing hole is reserved inside the tank for rinsing, so as to flush the sediment attached to the bottom and walls of the tank to the water collection pit, which facilitates the daily rinsing and maintenance of the tank.

[0041] To facilitate understanding of the present invention, the implementation process of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] This utility model provides a convenient flushing and emptying water tank device. Under normal operating conditions, the inlet and outlet valves of the water tank are open, while the emptying and flushing valves are closed. Water enters the water tank through the inlet pipe and inlet valve, flows in an S-shape along the guide wall, and is eventually guided to the outlet pit. Then, it flows to the subsequent water point through the outlet pipe and outlet valve at the bottom of the pit. The ventilation holes at the top of the guide wall and the ventilation pipes on the cover plate ensure air circulation inside the water tank and prevent odor accumulation. When the water flow is large and overflow occurs, the excess water first enters the overflow flare, then enters the overflow well through the overflow pipe, and after passing the overflow weir, it is discharged into the rainwater pipe system through the confluence pipe. Since the connection between the lift pipe and the overflow well is higher than the top of the overflow weir, the overflow water will not enter the emptying well through the lift pipe.

[0043] When the water tank needs to be emptied, the inlet and outlet valves are closed, and the venting valve is opened. Water between different corridors in the water tank is connected through the balance hole at the bottom of the guide wall. Water in two adjacent corridors and water in dead corners quickly converge into the sump. The water in the sump then enters the outlet pit through the drain pipe, and then enters the venting well through the outlet pipe, venting pipe, and venting valve. The water level in the water tank gradually decreases, while the water level in the venting well gradually increases. The level gauge monitors the water level in the water tank. When the water level in the water tank drops to a certain value, and the water level in the venting well rises to the pump start level, the coupled submersible sewage pump starts, quickly lifting the water in the venting well into the overflow well through the lift pipe. Due to the presence of the overflow weir, the water flow will not reverse and cross the overflow weir into the overflow pipe, but will enter the lower-level confluence pipe and then be discharged into the rainwater pipe system. Therefore, although the venting and overflowing conditions use the same discharge outlet, they do not interfere with or affect each other.

[0044] When the water level in the pool continues to drop to the minimum level, a person manually enters the pool through the maintenance manhole cover at the top of the flushing hole. Since the flushing hole is at a suitable height, the hose can be easily connected to the flushing hole. Then, the flushing valve is opened, and the flushing water enters the hose through the flushing pipe, flushing valve, and flushing hole, aiming at the sediment on the bottom and walls of the pool for flushing. The flushing water enters the sump and is discharged out of the system along with the drain water.

[0045] Inspection covers are installed on the top of the flushing holes, sump pits, and outlet pits of the water tank. Inspection covers are also installed on the top plates of the inlet well, outlet well, drain well, and overflow well to facilitate manual maintenance. When the coupled submersible sewage pump malfunctions, the inspection cover of the drain well is opened, and the submersible sewage pump is pulled up along the guide rail to facilitate maintenance or replacement of the submersible sewage pump. Moreover, the maintenance operation is carried out in the drain well, which does not affect the water quality of the water tank.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
