[0002] Buried water tanks are widely used in building water supply and drainage, fire-fighting water storage, and other systems. Because buried water tanks are located in an underground, enclosed environment, the water flow is poor, easily leading to stagnant water zones and water quality deterioration. Long-term stagnant water is prone to the growth of bacteria and algae, producing unpleasant odors and potentially forming biofilms, seriously affecting water safety. Therefore, this paper proposes a device to prevent stagnant water in buried water tanks to address these technical problems. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Example Please see Figure 1-3 This embodiment provides the following technical solution: a device to prevent dead water in an underground water tank, including a pump room 2 installed on one side of the water tank body 1.
[0017] A circulation pump 3 is fixedly connected inside the pump room 2. The inlet end of the circulation pump 3 is connected to a suction pipe 4 through a filter 8. The other end of the suction pipe 4 extends into the interior of the water tank body 1 and is fixedly connected to a suction bucket 5. The suction bucket 5 is fixedly connected to the inner wall of the water tank body 1. The outlet end of the circulation pump 3 is connected to a return pipe 6 extending into the interior of the water tank body 1. Multiple spray heads 7 are fixedly connected to the return pipe 6. Through the circulation pump 3, suction pipe 4 and return pipe, the water can be circulated inside the water tank by bottom suction and high return, which can prevent changes in the water quality inside the water tank and effectively ensure the water quality inside the water tank.
[0018] In some embodiments, the filter 8 adopts a lifting basket structure, wherein the filter 8 includes a cylinder 81, a cylinder cover 82 is detachably connected to the top of the cylinder 81, a filter basket 83 is provided inside the cylinder 81, a water inlet 84 is provided on one side of the cylinder 81, the water inlet 84 is connected to the water inlet end of the suction pipe 4, and a water outlet 85 is provided on the other side of the cylinder 81, the water outlet 85 is connected to the water outlet end of the circulation pump 3. The filter basket can be easily put in and taken out by workers, which is conducive to cleaning the filter basket 83 without draining the water tank, making the operation simple and convenient.
[0019] A sealing plate 86 is fixedly fitted on the outer side of the top of the filter basket 83 and fits against the inner wall of the cylinder 81. The sealing edge of the sealing plate 86 that fits against the outlet 85 is higher than the sealing edge of the sealing plate 86 that fits against the inlet 84. The "dam" design ensures that the water flow must completely fill the interior of the filter basket 83 and overflow from the raised edge before entering the outlet 85, thus forcing 100% filtration and preventing short circuit of the water flow.
[0020] In some embodiments, the water suction hopper 5 is located at the bottom of one side of the water tank body 1, and the water suction hopper 5 does not contact the bottom wall of the water tank body 1. The return water pipe 6 is located on the other side of the water tank body 1. The spray direction of the spray head 7 is set towards the water suction hopper 5. By adopting this diagonal arrangement of the water suction hopper 5 and the spray head 7, the most effective circulating flow field can be formed, and the dead water area can be minimized.
[0021] A valve is installed on the water suction pipe 4 to cut off the water flow during maintenance, and also to prevent water in the water tank body 1 from flowing into the cylinder 81 and affecting the cleaning of the filter basket 83 when cleaning the filter basket 83.
[0022] The suction bucket 5 has a funnel-shaped structure. An intercepting net is fixedly connected to the outside of the suction port of the suction bucket 5 to initially intercept large particles of impurities and also to reduce water inlet resistance.
[0023] The spray head 7 is a self-driven rotary nozzle. When high-pressure water flows through the nozzle, it drives the turbine inside the spray head 7 to rotate, which in turn drives the outer shell of the spray head 7 to rotate slowly through the reduction gear, forming a dynamic and three-dimensional swirling field, which significantly improves the mixing efficiency.
[0024] It also includes a timer controller, which is electrically connected to the circulating pump 3 and is used to automatically control the start and stop of the circulating pump 3.
[0025] In some embodiments, the timer controller can also be electrically connected to the water quality sensor inside the water tank body 1 to dynamically adjust the operation strategy of the circulation pump 3 based on water quality parameters such as residual chlorine, turbidity, and temperature, so as to achieve on-demand circulation and energy-saving operation.
[0026] The working principle of this utility model is as follows: The timer controller starts the circulation pump 3 according to the preset program. The water at the bottom of the pool is sucked in through the suction bucket 5 and enters the filter 8 through the suction pipe 4. Impurities are intercepted by the filter basket 83. Clean water enters the circulation pump 3 and is pressurized. It is then sprayed out from the spray head 7 through the return water pipe 6 in the form of a rotating jet, which promotes the circulation of water in the entire pool and effectively prevents the formation of stagnant water. During maintenance, close the valve on the inlet pipe, simply open the cover 82 of the filter 8, and remove the filter basket 83 for cleaning.
[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
