DETAILED DESCRIPTION

[0023] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments, and the following embodiments do not limit the invention involved in the claims. In addition, all combinations of the features described in the embodiments are not necessarily required for the solutions of the invention.

[0024] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example

[0026] like Figure 1 As shown, an intelligent water supply equipment includes a water pump 2 for connecting to a municipal pipe network 1, a first pressure sensor 3 for monitoring the water pressure of the municipal pipe network 1, a first flow sensor 4 for monitoring the water flow of the municipal pipe network 1, and a controller 5 for controlling the water pump 2, wherein the water pump 2 is a variable frequency pump.

[0027] It also includes a water tank 6, the water pump 2 is connected to the municipal pipeline 1 through a first control valve 7, the water pump 2 is connected to the water outlet of the water tank 6 through a second control valve 8, and the water inlet of the water tank 6 is connected to the municipal pipeline 1 through a third control valve 9. The controller 5 controls the working state of each control valve and the water pump 2 according to the information of the first pressure sensor 3 and the first flow sensor 4; for example, when it is detected that the pressure or flow of the municipal pipeline 1 is insufficient, the control valve is used to disconnect the municipal pipeline 1 from the water pump 2, so that the water pump 2 is connected to the water tank 6, and the water in the water tank 6 is used to supply water to the water demand side. The municipal pipeline 1 and the water tank 6 can also be connected to the water pump 2 at the same time, and both can be used to supply water to the water pump 2 at the same time to meet the demand for large water consumption. When the municipal pipeline 1 has sufficient water pressure, the municipal pipeline 1 can be connected to the water tank 6 to replenish the water tank 6. Of course, if the water tank 6 is a pressure water tank that can bear a certain pressure, the municipal pipeline 1 and the water tank 6 can be connected through a pressure pump, so that the pressure pump can be used to increase the water pressure inside the water tank 6. The water tank 6 can also be connected to the air pressure control device to inject high-pressure air into the water tank 6, thereby increasing the water pressure in the water tank 6, so as to increase the water supply pressure when the pressure of the water pump 2 is insufficient.

[0028] like Figure 2 , 3As shown, the water tank 6 includes an internal water storage chamber 61, and a cleaning module is arranged in the water storage chamber 61. The cleaning module includes a dirt collecting groove 10 corresponding to a part of the inner wall of the water storage chamber 61 and a groove sealing device for controlling the groove of the dirt collecting groove 10 to contact or stay away from the inner wall of the water storage chamber 61. When the groove of the dirt collecting groove 10 contacts the inner wall of the water storage chamber 61, the dirt collecting groove 10 and the corresponding inner wall of the water storage chamber 61 form a sealed cavity isolated from the outside. A cleaning device for removing dirt on the inner wall of the water storage chamber 61 is arranged in the dirt collecting groove 10, thereby achieving The inner wall of the water storage chamber 61 corresponding to the sump 10 is cleaned. The sump 10 is connected with an inlet pipe 11 and an outlet pipe 12, so that the dirt cleaned in the sealed chamber is discharged from the outlet pipe 12. The sump 10 is connected with an external sewage pump through the outlet pipe 12. The inlet pipe 11 can be connected to the water storage chamber 61 outside the sump 10, so that the sewage in the sump 10 is replaced by clean water in the water storage chamber 61. The inlet pipe 11 can also be connected to an external water supply device to control the water intake or the pressure in the sealed chamber. Since the cleaning work is carried out in the sealed chamber formed by the sump 10 and the inner wall of the water storage chamber 61, the dirt under cleaning is discharged in time, so that the water tank can be cleaned without stopping the equipment and affecting the water supply of the water tank. The cleaning module is controlled by the moving device to move in the water storage chamber 61, so as to clean the inner wall of different parts of the water storage chamber 61.

[0029] The cross section of the water storage chamber 61 of this embodiment is a vertical cylindrical chamber. The cleaning module includes a disc-shaped upper slider 13 and a lower slider 14 coaxial with the water storage chamber, and the size is equivalent to the cylindrical chamber. The upper slider 13 is connected to the middle of the lower slider 14 through a vertical pipe 15. The annular area surrounded by the upper slider 13, the lower slider 14 and the vertical pipe 15 is the sewage collection tank 10. The vertical pipe 15 connects the water storage chamber 61 on the upper and lower sides of the cleaning module, so that no matter where the cleaning module is located, the water bodies on both sides of the cleaning module can be connected, without affecting the connection between the water storage chamber 61 and the outside. Therefore, it does not affect the water supply to the outside.

[0030] The slot sealing device includes an upper sealing structure located at the circumferential edge of the upper slider 13 and a lower sealing structure located at the circumferential edge of the lower slider 14. The upper sealing structure includes an annular upper pressure chamber 16 located in the upper slider and opening toward the inner wall of the water storage chamber 61. The opening of the upper pressure chamber 16 is sealed with an upper elastic membrane 17. The lower sealing structure includes an annular lower pressure chamber 18 located in the lower slider and opening toward the inner wall of the water storage chamber 61. The opening of the lower pressure chamber 18 is sealed with a lower elastic membrane 19. The upper pressure chamber 16 and the lower pressure chamber 18 are connected to a pressure control device. The pressure control device controls the pressure of the fluid in the upper pressure chamber 16 and the lower pressure chamber 18, so that the elastic membrane can expand and contract relative to the inner wall of the water storage chamber 61. The pressure control device can be, for example, a pressure pump or other equipment that can feed fluid (water or gas) into the pressure chamber to control the pressure in the pressure chamber, such as Figure 2 As shown, when the pressure in the pressure chamber is high, the upper and lower elastic membranes expand radially toward the inner wall of the water storage chamber 61, thereby extruding and contacting with the inner wall of the water storage chamber 61, thereby achieving the sealing of the notch of the sewage collection tank 10 and the inner wall of the water storage chamber 61, thereby forming a sealed chamber; on the contrary, Figure 3 As shown, when the pressure in the pressure chamber is reduced, the upper and lower elastic membranes are radially retracted relative to the inner wall of the water storage chamber 61, so that the upper and lower elastic membranes are away from the inner wall of the water storage chamber 61, thereby facilitating the up and down movement of the cleaning module and avoiding the upper and lower elastic membranes from contacting the inner wall of the water storage chamber 61. The upper pressure chamber 16 and the lower pressure chamber 18 can be connected through a pipe 20 located in the wall of the vertical pipe 15, so that as long as the upper pressure chamber 16 is connected to the pressure control device through the connecting pipe 21, the upper and lower sealing structures can be controlled simultaneously. The connecting pipe 21 can pass through the top of the water storage tank and communicate with an external pump or other pressure control device.

[0031] The cleaning device of this embodiment includes two cleaning brushes 22 symmetrically arranged about the vertical pipe, the cleaning brush 22 includes a brush head in contact with the inner wall of the water storage chamber 61, the brush head is provided with bristles in contact with the inner wall of the water storage chamber 61, the cleaning brush 22 is controlled by a motor to rotate around the vertical pipe 15, the bristles are arranged on a connecting rod, the vertical pipe 15 is sleeved with an outer rotor motor 23, the connecting rod is connected to the outer rotor of the outer rotor motor 23, so that the cleaning brush 22 can be controlled to rotate around the vertical pipe 15, so as to use the bristles to clean the dirt on the inner wall of the water storage chamber 61. Of course, the motor should be a waterproof motor suitable for use in water. The distance between the outlet pipe 12 and the brush head is less than the distance between the inlet pipe 11 and the brush head, so that the sewage at the brush head position can be quickly discharged. The outlet pipe 12 and the inlet pipe 11 of this embodiment pass through the upper pressure chamber 16. The outlet pipe passes through the upper part of the water storage tank and is connected to an external sewage pump and other equipment. The connecting rod may be a telescopic rod, so as to facilitate controlling the distance between the brush head and the inner wall of the water storage chamber 61 .

[0032] The cleaning module further includes a guide rod 24 located in the middle of the water storage chamber 61, the guide rod 24 passes through the vertical pipe 15, and a guide wheel 25 is supported between the vertical pipe 15 and the guide rod 24 to provide a guide for the movement of the cleaning module. A certain gap is maintained between the guide rod 24 and the vertical pipe 15 to facilitate the communication between the water storage chambers 61 on both sides.

[0033] The moving device may be a traction rope 26, and the up and down movement of the cleaning module may be controlled by a traction rope 26 retracting device.

[0034] The bottom of the water storage chamber 61 is a conical chamber 611, and the bottom of the conical chamber 611 is connected to the sewage pipe 30, so that some impurities with higher density in the water sink to the bottom of the conical chamber 611 and are discharged from the sewage pipe 30. Of course, the sewage pipe 30 is usually closed and is only opened when sewage needs to be discharged.

[0035] The lower end of the guide rod 24 has a nozzle 27 corresponding to the inner wall of the conical cavity 611. The nozzle 27 is connected to a high-pressure water supply device, so that a high-pressure water flow can be sprayed toward the inner wall of the conical cavity 611, thereby cleaning the dirt on the inner wall of the conical cavity 611. The guide rod 24 has a cavity inside, that is, the guide rod 24 is a tube body, so that the nozzle 27 and the external high-pressure water supply device can be connected through the guide rod 24.

[0036] It also includes a second pressure sensor 28 for detecting the liquid pressure in the water storage chamber 61 and a third pressure sensor 29 for detecting the water pressure in the sewage collection tank 10, so that the sewage in the sewage collection tank 10 is slightly lower than the water pressure in the external water storage chamber 61 by using the sewage pump, thereby preventing the sewage in the sewage collection tank 10 from entering the water storage chamber 61. The second pressure sensor 28 is located above the upper slider 13, and the third pressure sensor 29 is arranged below the upper slider 13.

[0037] If there are multiple water supply pipelines in the municipal pipe network 1 at the installation location of the water supply device, the water tank 6 and the water pump 2 can be connected to different pipelines of the municipal pipe network 1 respectively, so as to avoid mutual influence when the water is taken in by the two. The height difference between the water inlet and the water outlet of the water tank 6 is less than the height of the sewage collection tank 10, so that the water inlet and the water outlet of the water tank 6 can be located in the sewage collection tank 10 at the same time, so that when necessary, Figure 4 As shown, the water inlet and the water outlet are directly connected through the sewage collecting tank 10 without passing through the water storage chamber 61. In this way, the water pump 2 can be supplied with water by the pipeline connected to the water storage tank 6, avoiding the water in the water storage chamber 61 from entering the water pump 2 at the same time.

[0038] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described, or replace them in similar ways, without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
