[0002] Urban water supply networks suffer from severe leakage and uneven pressure distribution due to factors such as pipe corrosion and aging, and improper construction of buildings and roads. This not only affects the normal water supply of cities but also wastes a significant amount of water resources. Therefore, under the premise of meeting the normal water needs of cities, it is of great significance and importance to take pressure management measures to reduce leakage and balance the pressure of the pipeline network.

[0003] Chinese Patent CN213653595U discloses a booster water supply device for urban water supply networks in limestone areas. This invention employs a compensating pump, controller, and pressure sensor. The pressure sensor detects water pressure and transmits the data to the controller. When water pressure is insufficient during peak water usage periods, the controller activates the compensating pump to pressurize the drainage pipes, ensuring sufficient water pressure. The design incorporates a filter screen and filter head to remove impurities from the network, thus ensuring the health of residents' water supply.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: after a period of use, some scale will accumulate on the inner wall of the pressure stabilizing tank. The inner wall of the pressure stabilizing tank is inconvenient to clean, which brings difficulties to the cleaning work. If the scale is not cleaned in time, the water quality will be reduced.

[0018] Example 1

[0019] like Figures 1 to 3 As shown, the present invention proposes an underground water supply network booster device, including a water supply tank 1, a support 3, and a cleaning assembly; a cover plate 101 is detachably installed on the top of the water supply tank 1 by bolts, and a booster pump assembly 2 is installed on the bottom of its side wall. A solenoid valve 201 is provided between the booster pump assembly 2 and the water supply tank 1. The output end of the booster pump assembly 2 is connected to the underground water supply network. A pressure sensor is provided on the underground water supply network, and the pressure sensor probe extends into the interior of the underground water supply network. The booster pump assembly 2 consists of a booster pump, a suction pipe, a filter box, a filter screen, and a filter head; the support 3 is installed on the upper inner wall of the water supply tank 1, and a drive assembly is detachably installed on the support 3; the cleaning assembly is detachably connected to the drive assembly, and the cleaning assembly is driven by the drive assembly to rotate along the inner wall of the water supply tank 1. The cleaning assembly consists of a rotating rod 5, a mounting bracket 502 installed on the side wall of the rotating rod 5, and a scraper 503 and a cleaning brush 504 installed on the mounting bracket 502.

[0020] Furthermore, the bracket 3 has an installation port in the middle, and the drive assembly includes a mounting plate 4 and a rotating shaft 401; the mounting plate 4 is connected to the top of the bracket 3 by bolts; the rotating shaft 401 passes through the installation port and is connected to the stepper motor at the top of the mounting plate 4 for transmission, and the bottom end of the rotating shaft 401 extends to the bottom of the installation port and is detachably connected to the rotating rod 5.

[0021] Furthermore, the mounting bracket 502, scraper 503, and cleaning brush 504 are all L-shaped. The scraper 503 and cleaning brush 504 are in contact with the bottom and side wall of the water supply tank 1. The scraper 503 is a rubber scraper. The scraper 503 and cleaning brush 504 can be squeezed to an appropriate degree. When the rotating rod 5 is inserted into the water supply tank 1, the rotating rod 5 is pressed down to make the bottom of the scraper 503 and cleaning brush 504 bend, so that the plug seat 501 can be inserted along the limiting cavity 402. When the top of the plug seat 501 abuts against the limiting cavity 402, the bottom of the scraper 503 and cleaning brush 504 still remain in contact with the bottom of the water supply tank 1.

[0022] In this embodiment, an appropriate amount of water is input into the water supply tank 1 through the inlet valve. The output end of the booster pump assembly 2 is connected to the underground water supply network. When the pressure sensor installed on the underground water supply network detects that the water pressure inside the pipe is lower than the set threshold, the monitoring information is transmitted to the controller. The controller then starts the booster pump assembly 2 to pump water from the water supply tank 1 and deliver it to the water supply network to maintain stable water pressure. After a period of use, the valve port of the solenoid valve 201 between the booster pump assembly 2 and the water supply tank 1 is closed. The bolts between the cover plate 101 and the water supply tank 1 are removed, and the cover plate 101 is separated from the water supply tank 1. The rotating shaft 401 is passed through the mounting port on the bracket 3, and the mounting plate 4 is fixedly connected to the bracket 3 by bolts. Then, the cleaning assembly is... The rotating rod 5 is inserted into the water supply tank 1 and quickly installed with the rotating shaft 401. This allows for the removal of scale from the upper part of the inner wall of the water supply tank 1. Water is then sprayed onto the inner wall of the water supply tank 1, and the controller starts the stepper motor to drive the rotating shaft 401 to rotate, which in turn drives the rotating rod 5 to rotate. The rotation of the rotating rod 5 drives the scraper 503 and cleaning brush 504 on the mounting bracket 502 to rotate, removing scale from other parts of the inner wall of the water supply tank 1. The wastewater after cleaning is discharged along the drain valve at the bottom of the side wall of the water supply tank 1. This makes cleaning more convenient and faster. The cleaning components and drive components are easy to disassemble and assemble, so they do not need to be soaked in water to accumulate scale. This also makes maintenance easier. When it is necessary to clean the inner wall of the water supply tank 1, it can be quickly assembled, bringing convenience to the cleaning work.

[0023] Example 2

[0024] like Figure 3 and Figure 4 As shown, the underground water supply network booster device proposed in this utility model, compared with the first embodiment, has a plug-in seat 501 installed at the top of the rotating rod 5, a limiting cavity 402 opened at the bottom of the rotating shaft 401, a limiting component provided on the limiting cavity 402, and the plug-in seat 501 is detachably connected to the limiting cavity 402 through the limiting component.

[0025] Furthermore, the limiting assembly includes a slide rod 403 and an elastic element 404; the slide rod 403 is slidably connected to the rotating shaft 401, and two sets of slide rods 403 are provided. One end of the slide rod 403 extends into the limiting cavity 402 and a wedge block 405 is installed therein. The wedge block 405 is slidably connected to the limiting cavity 402. The end of the wedge block 405 away from the slide rod 403 abuts against the insertion seat 501. The insertion seat 501 is inserted into the limiting cavity 402. The top end of the rotating rod 5 abuts against the bottom end of the rotating shaft 401; the elastic element 404 is installed between the side wall of the rotating shaft 401 and one end of the slide rod 403. The elastic element 404 is a spring and is sleeved on the outside of the slide rod 403.

[0026] Furthermore, the plug-in base 501 is composed of two sets of blocks with triangular and rectangular cross-sections. The end of the wedge block 405 away from the slide bar 403 abuts against the connection between the two sets of blocks. The top of the plug-in base 501 abuts against the top of the limiting cavity 402. The lower end of the plug-in base 501 is slidably connected to the limiting cavity 402.

[0027] In this embodiment, the rotating rod 5 is inserted into the water supply tank 1 and the scraper 503 and cleaning brush 504 are pressed downward with appropriate force so that the plug seat 501 can be inserted into the limiting cavity 402. When the plug seat 501 moves upward along the limiting cavity 402, the top of the plug seat 501 presses the wedge block 405 towards the elastic member 404, so that the elastic member 404 is compressed. As the plug seat 501 continues to move upward, under the elastic force recovery of the elastic member 404, the wedge block 405 is driven to abut against the rectangular block in the top cross-section of the plug seat 501. At this time, the top of the plug seat 501 abuts against the top of the limiting cavity 402, and then the wedge block 405 locks the plug seat 501 in the limiting cavity 402, so that the rotating rod 5 and the rotating shaft 401 can be quickly connected, and the disassembly and assembly are convenient and quick.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
