[0002] Superimposed water supply equipment and non-negative pressure water supply equipment require the use of a turbulence tank. Ordinary turbulence tanks generally cannot be cleaned inside the turbulence tank from the time of use. The maintenance of ordinary turbulence tanks only empties the water inside the turbulence tank, and cannot clean the debris inside the turbulence tank, which will lead to the inability to ensure the safety of the water quality inside the turbulence tank; at the same time, ordinary turbulence tanks usually adopt a fully enclosed structure or a manually operated exhaust structure, which is difficult to clean and maintain. To this end, the present invention provides a turbulence tank for superimposed water supply equipment with a self-cleaning device, which can automatically clean the turbulence tanks used for superimposed water supply equipment and non-negative pressure water supply equipment, avoid cleaning difficulties during use, or the impact on water quality caused by long-term lack of maintenance and cleaning, and ensure water quality safety. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems of difficulty in cleaning ordinary turbulence tanks for superimposed and non-negative pressure water supply equipment, inability to ensure the safety of the water quality inside the turbulence tank, and difficulty in cleaning and maintenance. The present invention solves the problems of difficulty in cleaning ordinary turbulence tanks for superimposed and non-negative pressure water supply equipment, inability to perform controlled cleaning, and inability to ensure the safety of the water quality inside the turbulence tank. It can perform all-round automatic controlled cleaning of the interior of the turbulence tank, is easy to disassemble and maintain, and is suitable for promotion and use as a self-cleaning turbulence tank in water supply equipment.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A flow stabilizing tank for a superimposed water supply device with a self-cleaning device comprises a flow stabilizing tank body having a mounting port provided with a flange, and is characterized in that it further comprises:

[0006] A rotating assembly is provided inside the flow stabilizing tank, one end of which is mounted on a flange. An actuator is provided on the outer end of the rotating assembly mounted on the flange. The actuator can adjust and control the rotating assembly inside the flow stabilizing tank to rotate, and the rotation angle range is fan-shaped.

[0007] The rotating assembly is also provided with a nozzle assembly, which includes a rotating nozzle and a cleaning rotating member. The rotating nozzle is mounted on the cleaning rotating member, and the cleaning rotating member can rotate on the rotating assembly together with the rotating nozzle.

[0008] Through the rotational cooperation of the rotating assembly and the nozzle assembly, the interior of the flow stabilizing tank can be cleaned in all directions, ensuring the safety of water quality in the flow stabilizing tank for water supply equipment.

[0009] In order to enable the rotating shaft in the rotating assembly to rotate within a small angle range inside the stabilizing tank body and to adjust the rotation angle and direction, the rotating assembly further comprises a rotating shaft, one end of which is mounted on a flange, and an actuator is provided on the outer end of the rotating shaft mounted on the flange. The actuator can adjust and control the rotation angle and direction of the rotating shaft inside the stabilizing tank body, and the rotation angle is less than 10°;

[0010] The other end of the rotating shaft is rotatably riveted to the inner wall of the flow stabilizing tank body. The position where the other end of the rotating shaft is riveted to the inner wall of the flow stabilizing tank body is on the same horizontal line as the position where one end of the rotating shaft is mounted on the flange. The rotating shaft can rotate at the riveted joint. The angle of rotation of the rotating shaft at the riveted joint is equal to the angle of rotation of the rotating shaft controlled by the actuator. The riveted joint and the actuator match each other, and the rotation angle and rotation direction of the rotating shaft can be adjusted and controlled.

[0011] In order to enable the nozzle assembly to rotate left or right on the rotating shaft, further, a threaded structure is provided in the middle of the rotating shaft, and the cleaning rotating member in the nozzle assembly is screwed onto the threaded structure in the middle of the rotating shaft. The rotating nozzle is mounted on the cleaning rotating member. The rotating nozzle can rotate clockwise or counterclockwise under the action of the reverse thrust of the deflected water spray, thereby pushing the cleaning rotating member to rotate left or right on the threaded structure in the middle of the rotating shaft;

[0012] The cleaning rotating member can rotate together with the rotating nozzle on the rotating shaft of the rotating assembly, and the range of rotation can be an integer multiple of a 360° circumferential angle.

[0013] In order to ensure that the nozzle assembly can only rotate within a certain range on the rotating shaft and ensure that it does not run out of the threaded structure area, further, fixed brackets are provided at both ends of the threaded structure on the rotating shaft. The fixed brackets can limit the cleaning rotating part so that the cleaning rotating part moves on the threaded structure in the middle of the rotating shaft and cannot completely run out of the threaded structure area in the middle of the rotating shaft.

[0014] In order to make the rotating nozzle in the nozzle assembly rotate smoothly and generate a reverse thrust of the deflected water spray so that the cleaning rotating part can rotate on the rotating shaft, further, the rotating nozzle is a three-corner plum blossom shape. The three-corner plum blossom-shaped rotating nozzle can push the cleaning rotating part to rotate left or right on the threaded structure in the middle of the rotating shaft under the action of the reverse thrust of the deflected water spray, so that the rotating nozzle rotates smoothly.

[0015] In order to deliver cleaning water to the cleaning rotating part and control the cleaning time and frequency, a cleaning hose is further provided on the cleaning rotating part, the tail end of the cleaning hose is connected to the cleaning water inlet pipe, the cleaning water inlet pipe is installed on the flange on the outside of the stabilizing tank body, and a cleaning solenoid valve is provided on the cleaning water inlet pipe on the flange on the outside of the stabilizing tank body. The cleaning solenoid valve is connected to the control cabinet through a wiring harness, and a control system component is provided in the control cabinet. The control system component can realize the control of the nozzle assembly to automatically clean the inside of the stabilizing tank body or close the nozzle assembly by controlling the switching state of the cleaning solenoid valve;

[0016] The cleaning hose is made of a soft material with good elasticity, and can be restored to its original state after cleaning so as to be used for the next cleaning;

[0017] The control system components in the control cabinet can be set to control the cleaning time and frequency.

[0018] In order to prevent the cleaning hose from being entangled on the rotating shaft and hindering the movement of the cleaning rotating part on the rotating shaft, a protective kit is further provided on the outer side of the lower part of the cleaning rotating part. The protective kit moves left or right on the rotating shaft together with the cleaning rotating part. The protective kit can prevent the cleaning hose on the cleaning rotating part from being entangled on the rotating shaft, and the cleaning hose can be wrapped around the outside of the protective kit.

[0019] In order to enable the flow stabilizing tank to take in and out water, and at the same time to ensure that the sewage after cleaning can be discharged from the flow stabilizing tank, further, the flow stabilizing tank is provided with a water inlet and a water outlet, and a sewage outlet is provided at the lowest point of the flow stabilizing tank. The water inlet, the water outlet and the sewage outlet are respectively connected to pipes, and an inlet electric valve is provided on the water inlet pipe, a water outlet electric valve is provided on the water outlet pipe, and a sewage solenoid valve is provided on the sewage outlet pipe;

[0020] The water inlet electric valve, the water outlet electric valve and the sewage discharge solenoid valve are respectively connected to the control cabinet through a wiring harness. A control system component is provided in the control cabinet. The control system component can control the switching status of the water inlet electric valve, the water outlet electric valve and the sewage discharge solenoid valve. The control system component controls the addition of water to the interior of the stabilizing flow tank or closes the water inlet by controlling the switch of the water inlet electric valve; the control system component controls the discharge of water from the interior of the stabilizing flow tank or closes the discharge of water by controlling the switch of the water outlet electric valve; the control system component controls the discharge of sewage from the cleaned water in the stabilizing flow tank or closes the discharge of sewage by controlling the switch of the sewage discharge solenoid valve;

The control system component can control the actuator to control the rotation angle and rotation direction of the rotating component inside the flow stabilizing tank.

[0022] In order to prevent the sewage from being unable to flow out of the water outlet during the cleaning of the stabilizing tank, a pull rod is provided on the rotating shaft of the rotating assembly, and a cover plate is provided at the lower part of the pull rod. The cover plate is located above the water outlet inside the stabilizing tank as a whole, and the horizontal dimension of the cover plate is greater than 1.5 times the diameter of the water outlet inside the stabilizing tank.

[0023] The rotation of the rotating shaft can drive the cover plate to rotate together through the pull rod. The angle of rotation of the rotating shaft, pull rod and cover plate together is less than 10°, and it can ensure that the cover plate completely covers the water outlet inside the stabilizing tank body after rotation, so that the sewage from cleaning the inside of the stabilizing tank body does not flow out from the water outlet.

[0024] In order to facilitate the maintenance and disassembly of the rotating assembly and the nozzle assembly, while ensuring the overall stability of the flow stabilizing tank, the rotating assembly and the flange, the rotating assembly and the actuator, and the rotating assembly and the nozzle assembly are all connected by a detachable structure.
