Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] Please see Figures 1 to 3 It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0043] This utility model provides a water supply maintenance well, such as Figure 1 and Figure 2 As shown, the water supply maintenance well includes a well body 10, which includes a well chamber 11 and a well cover 12. A well cover support 110 is provided above the well chamber 11, and the well cover 12 is sealed to the well cover support 110. A water collection pit 20 is provided at the bottom of the well chamber 11, and the height of the bottom wall of the well chamber 11 gradually increases from the end near the water collection pit 20 to the end away from the water collection pit 20. A water pump 201 is provided in the water collection pit 20, and a water level sensor 202 is provided on the top edge of the water collection pit 201. A water supply pipe 30 is provided in the well chamber 11, and a first electric on / off valve 3 is provided on the water supply pipe 30. The well chamber 11 contains a flow sensor (not shown in the figure). An information transmission module 40 is provided at one end of the well chamber 11 away from the sump 20. The information transmission module 40 is communicatively connected to the flow sensor. The well chamber 11 also includes a control unit (not shown in the figure). The water level sensor 202, the water pump 201, the first electric on / off valve 301, and the information transmission module 40 are all communicatively connected to the control unit. Specifically, a power supply module 50 is also provided at one end of the well chamber 11 away from the sump 20. The power supply module 50 is used to supply power to the water pump 201, the first electric on / off valve 301, the information transmission module 40, and the control unit.

[0044] The beneficial effects of this utility model's water supply maintenance well are as follows: During use, the water flow information of the water supply pipeline 30 is detected in real time by a flow sensor, and the water flow information is transmitted to the control unit through the information transmission module 40. The control unit can be connected to the water supply network water control system. When the detected water flow information increases in time, the water supply pipeline may have burst or leaked. At this time, the maintenance personnel should check the water supply pipeline. If the water supply pipeline bursts after the check, the first electric on / off valve 301 on the water supply pipeline 30 can be closed in time through the control unit, and then the water supply pipeline can be repaired. Furthermore, because the manhole cover 12 and the manhole cover support 110 of this utility model are sealed together, rainwater can be effectively prevented from entering the manhole chamber 11. By setting the bottom wall of the manhole chamber 11 as a slope with one end higher than the other, and setting a sump 20 at the lower end, condensate water inside the manhole and a small amount of groundwater seeping into the manhole chamber 11 can be collected in the sump 20, effectively preventing water accumulation in the manhole chamber 11. This effectively prevents water from corroding and damaging the electric on / off valve, flow sensor, information transmission module, and power supply module on the water supply pipeline. And when the water supply pipeline 30 bursts, because... The bottom wall of the well chamber is sloping, so the sprayed water can be collected in the sump 20 in a timely manner. When the sump 20 is full of water, that is, when the water level inside the sump 20 reaches the same level as the bottom wall of the well chamber 11, the water level sensor 202 will be triggered. The water level sensor 202 will send a signal to the control unit. The control unit will control the water pump 21 to start in a timely manner according to the signal sent by the water level sensor 202, so as to discharge the water in the sump 20 to the outside of the well chamber. This can further prevent the water accumulated in the well chamber 11 from damaging the electric on / off valve and flow sensor on the water supply pipeline, as well as the information transmission module and power supply module. In summary, compared with existing technologies, the water supply maintenance well of this utility model can effectively prevent water accumulation in the well chamber, thereby effectively improving the service life of devices such as electric on / off valves and flow sensors on the water supply pipeline, reducing maintenance frequency, and eliminating the need for pumping water when maintenance personnel perform regular maintenance. This greatly reduces the workload of maintenance of municipal water supply network maintenance wells, lowers labor costs, and improves maintenance efficiency.

[0045] Specifically, such as Figure 2 As shown, in this embodiment, a low-voltage conduit 101 and a high-voltage conduit 102 are pre-embedded in the well wall of the well chamber 11, and the signal line and power line can be connected to the outside through the low-voltage conduit 101 and the high-voltage conduit 102 respectively.

[0046] Specifically, in this embodiment, a sealing ring is provided between the manhole cover 12 and the manhole cover support 110, that is, in this embodiment, the manhole cover 12 and the manhole cover support 110 are sealed together by the sealing ring. The structure is simple and the cost is low.

[0047] Furthermore, considering that the sealed connection between the manhole cover 12 and the manhole cover support 110 can easily cause negative pressure to form inside the manhole chamber 11, making it difficult to open the manhole cover 12, it is preferable that, in this embodiment, if... Figure 1 and Figure 3 As shown, a valve core 120 is provided on the manhole cover 12. The valve core 120 is normally closed, thus preventing rainwater from entering the manhole chamber 11 through it. When it is necessary to open the manhole cover 12, the valve core 120 can be opened by pressing its core post, thereby connecting the manhole chamber 11 to the outside and eliminating the negative pressure inside the manhole chamber 11, thus facilitating the opening of the manhole cover 12. Specifically, the valve core described above is a conventional structure in the prior art. For example, the valve core can be the valve core structure on a bicycle wheel, or it can be the valve core structure disclosed in patent number ZL201510027917.5. Therefore, the structure of the valve core will not be described in detail here.

[0048] Furthermore, to prevent vehicles from damaging the valve core 120 when passing over the manhole cover 12, preferably, in this embodiment, as follows: Figure 1 As shown, the valve core 120 is recessed on the manhole cover 12, meaning that the top of the valve core 120 is lower than the surface of the manhole cover 12.

[0049] Furthermore, to prevent groundwater from potentially seeping into the well chamber 11, preferably, in this embodiment, an anti-seepage coating is provided on the inner walls around the well chamber 11 and the bottom wall. This anti-seepage coating can prevent water from seeping into the interior of the well chamber 11. Preferably, in this embodiment, the anti-seepage coating is a polyurethane coating or a cement-based penetrating crystallizing coating.

[0050] To further improve the safety and stability of the information transmission module 40 and the power supply module 50, and to prevent water accumulation on the bottom wall of the well chamber 11 from affecting the information transmission module 40 and the power supply module 50, preferably, as follows: Figure 2 As shown, in this embodiment, an installation platform 111 is provided on the bottom wall of the well chamber 11. The installation platform 111 is at a certain height above the bottom wall of the well chamber 11, and the information transmission module 40 and the power supply module 50 are mounted on the installation platform 111. Because of the installation platform 111, even if there is water accumulation at the bottom of the well chamber 11, it will not affect the information transmission module 40 and the power supply module 50. It is understood that in this embodiment, the installation platform 111 is located at the end away from the sump.

[0051] Furthermore, such as Figure 2As shown, in this embodiment, a water quality analyzer 60 is also installed in the well chamber 11. The water quality analyzer 60 is communicatively connected to the information transmission module 40 and electrically connected to the power supply module 50. The water quality analyzer 60 is connected to the water supply pipeline 30 through a sampling pipe 601. A second electric on / off valve (not shown in the figure) is installed on the sampling pipe 601. The second electric on / off valve is electrically connected to the power supply module 50 and is also communicatively connected to the control unit. In use, the second electric on / off valve can be opened periodically by the control unit, so that the water quality analyzer 60 can periodically test the water quality in the water supply pipeline 30 and transmit the test results to the control unit through the information transmission module 40. When the test results of the water quality analyzer 60 do not meet the relevant national standards, the control unit will promptly close the first electric on / off valve 301 on the water supply pipeline 30, that is, promptly cut off the water supply, and then promptly notify the operation and maintenance personnel to investigate and test the water quality, thereby ensuring the water supply quality.

[0052] Specifically, to improve the stability and reliability of the water quality analyzer 60, and to prevent potential water accumulation on the bottom wall of the well chamber 11 from affecting the analyzer 60, it is preferable that, in this embodiment, the water quality analyzer 60 is also mounted on the installation platform 111. Specifically, the wastewater detected by the water quality analyzer 60 can be discharged into a sewage well through a pipe.

[0053] Furthermore, such as Figure 1 As shown, in this embodiment, a grating cover 203 is also provided on the top of the sump 20, and the grating cover 203 has multiple through holes. Through the installation of the grating cover 203, while not affecting the flow of water from the bottom wall of the well chamber into the sump 20, the grating cover 203 also provides a standing space for maintenance personnel when they go down into the well for maintenance, preventing them from falling into the sump 20. It also provides more space for maintenance personnel to work inside the well chamber 11, improving the convenience and safety of their work. Specifically, in this embodiment, the grating cover is made of steel.

[0054] Furthermore, such as Figure 1 As shown, in this embodiment, a one-way drain valve 204 is also provided at the bottom of the sump 20. A drain pipe 2041 is connected to the one-way drain valve 204, and the drain pipe 2041 extends to the outside of the well chamber 11. The one-way drain valve 204 is used to discharge the water in the sump 20 to the outside (sewage well). In use, the one-way drain valve is in the normally open state. The one-way drain valve 204 can directly discharge the small volume of condensate or groundwater infiltration collected in the well chamber to the outside, thereby avoiding the need to frequently start the water pump and reducing operation and maintenance costs.

[0055] Furthermore, in this embodiment, a pressure sensor can also be installed on the water supply pipe 30. The pressure sensor is communicatively connected to the information transmission module. By installing the pressure sensor, the water supply pressure can be detected. Therefore, in use, the water supply situation can be comprehensively analyzed by the water supply flow information detected by the flow sensor and the water supply pressure information detected by the pressure sensor, which can improve the accuracy and precision of water supply detection.

[0056] In summary, the water supply maintenance well of this invention effectively prevents water accumulation in the well chamber, thereby significantly extending the service life of devices such as electric on / off valves and flow sensors on the water supply pipeline. This reduces maintenance frequency, and eliminates the need for pumping water during regular maintenance by operation and maintenance personnel. This greatly reduces the workload of maintenance of municipal water supply network maintenance wells, lowers labor costs, and improves maintenance efficiency. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.

[0057] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
