Abstract
Description
Technical Field
[0001] This utility model relates to the field of water supply and drainage technology, and in particular to a prefabricated water supply inspection well with flood prevention and leak detection functions. Background Technology
[0002] Water supply inspection wells are well-shaped structures installed at the ends, branches, low-lying areas, and valve locations of water supply networks for regular inspection and maintenance. They are equipped with valves, elbows, tees, and other pipe fittings, playing a crucial role in pipeline maintenance, flow regulation, and drainage to ensure the stable operation of urban water supply systems. Wastewater in water supply inspection wells mainly originates from rainwater or clean wastewater flowing in from roads outside the well, or from leaks at pipe connections within the well. Wastewater in water supply inspection wells can be collected by installing sump pits.
[0003] However, since traditional water supply inspection wells lack a device for actively draining accumulated sewage, sewage in these wells is currently mainly removed through manual inspection or by connecting a self-priming pump after overflow is discovered. Because the amount of sewage accumulated in the well cannot be monitored in real time, if a large amount of sewage enters the inspection well in a short period or if the accumulated sewage is not drained in a timely manner, it may cause sewage to flood the water supply pipes, leading to corrosion and even contamination of the tap water, seriously threatening the safety of residents' water supply.
[0004] Furthermore, the installation and construction of traditional water supply inspection wells are time-consuming and labor-intensive, with severe weather extending the construction period. Subsequent maintenance and replacement of components are also quite troublesome. In contrast, prefabricated structures are less affected by weather changes; components are manufactured in the factory and transported directly to the site for assembly, reducing on-site construction steps and accelerating the construction progress. Therefore, to address the above problems, a prefabricated water supply inspection well with flood prevention and leak detection functions is proposed. Utility Model Content
[0005] In view of this, the present invention provides a prefabricated water supply inspection well with flood prevention and leak detection function to solve the problems mentioned in the background art, such as the inability of traditional water supply inspection wells to timely remove accumulated sewage, detect and resolve pipe leaks in the well, resulting in water supply pipe corrosion and water source pollution, as well as the time-consuming and cumbersome construction and installation of traditional water supply inspection well structures.
[0006] This utility model discloses a prefabricated water supply inspection well with flood prevention and leak detection function, including a well body and a well bottom that is plugged into the well body to form an assembly. The inner surface of the bottom of the well bottom is set as an inclined surface, and a water collection pit is set at the bottom of the well bottom at the low position corresponding to the inclined surface. Inside the well bottom, above the water collection pit, a liquid level detector is set to monitor the liquid level in the water collection pit.
[0007] In other words, in this invention, the inner bottom of the inspection well is inclined. By using an inclined surface on the inner surface of the bottom of the well, water entering the inspection well can automatically flow to a lower position on the inner surface of the bottom of the well under its own gravity. Simultaneously, a sump is provided at the lower position corresponding to the inclined surface inside the well, allowing the water entering the inspection well to automatically collect into the sump, thus achieving automatic collection of the water entering the inspection well. Furthermore, by using a level detector installed at the bottom of the well to monitor the liquid level in the sump, changes in the liquid level in the sump can be monitored in real time, allowing the collected water in the sump to be discharged when the water level at the bottom of the well reaches a certain height.
[0008] Furthermore, in this invention, since the well bottom and the well body are assembled by a plug-in method, it is easier to carry out on-site construction and installation as well as subsequent maintenance and replacement compared to the traditional installation method of inspection wells.
[0009] According to the prefabricated water supply inspection well with flood prevention and leak detection function disclosed in this utility model, the inclination angle of the inclined surface is 1-3°. In a preferred embodiment, the inclination angle of the inclined surface is 1°, and in other embodiments, the inclination angle of the inclined surface can also be 2° or 3°. In this utility model, the inclination angle is relative to the horizontal plane of the ground. That is, when the inclination angle is 1°, it means that the angle between the inner surface of the bottom of the well and the horizontal plane of the ground (or the plane parallel to the horizontal plane of the ground) is 1°.
[0010] The prefabricated water supply inspection well with flood prevention and leak detection function disclosed in this utility model also includes an information alarm system. The information alarm system includes an alarm device and a control terminal. The alarm device is installed at the bottom of the well. The alarm device is connected to a liquid level detector to obtain liquid level information in the sump. The control terminal is located outside the inspection well. The alarm device is connected to the control terminal via remote signal transmission to transmit the liquid level information in the sump received from the liquid level detector to the control terminal. Based on whether it is raining at the current time and / or the liquid level information, the control terminal can determine the cause of the current water ingress into the inspection well.
[0011] With the help of an information alarm system, once water has been collected in the sump, the liquid level information (or signal) in the sump can be transmitted in real time to the control terminal, allowing the control terminal to determine the cause of water accumulation in the sump. In this invention, the control terminal is a remote control terminal, which can be a central controller or a computer, iPad, or other hardware processor with central data processing capabilities. The alarm device can be an existing signal transmission device, which establishes a signal connection with the control terminal through remote signal transmission.
[0012] After receiving the liquid level information from the alarm device, the control terminal can determine the cause of water ingress into the inspection well based on whether it is raining at the current time and the received liquid level information. Specifically, for example, if it is raining at the current time, the control terminal can determine that the cause of water ingress is an occasional external water discharge; if it is not raining at the current time, the control terminal can determine that the cause of water ingress is a leak caused by a damaged water supply pipe, thus enabling timely detection of pipe leakage.
[0013] It should be noted that the signal conversion and / or calculation used by the control terminal to determine the cause of water ingress are implemented using existing technology, and will not be elaborated here. In other words, the technical solution claimed in this utility model does not involve any improvement to software, programs, or algorithms, but only to the improvement of the connection relationship between hardware devices (such as the control terminal, alarm device, and liquid level detector).
[0014] According to the prefabricated water supply inspection well with flood prevention and leak detection function disclosed in this utility model, a submersible pump is installed in the sump. The submersible pump is connected to a liquid level detector, so that when the liquid level detector detects that the liquid level in the sump exceeds the threshold, it sends a signal to start the submersible pump to perform drainage work.
[0015] In this invention, the liquid level detector can be any existing sensor capable of monitoring changes in liquid level, as long as it can monitor changes in liquid level in the sump in real time.
[0016] By connecting the submersible pump to a level detector, when the level detector detects that the liquid level in the sump exceeds a threshold, the level detector can directly send a control command to the submersible pump to control it to perform drainage. This can be achieved by installing a controller (such as a CPU processor) on the level detector or the submersible pump, which is existing technology and will not be elaborated further here.
[0017] Those skilled in the art will also understand that the operation of the submersible pump can be controlled by an external control terminal (such as those mentioned below). In this case, the level detector is connected to the external control terminal, and the control terminal is connected to the submersible pump. Specifically, when the level detector detects that the liquid level in the sump exceeds a threshold, it can transmit a signal indicating that the current liquid level exceeds the threshold to the external control terminal. After receiving the signal indicating that the current liquid level exceeds the threshold, the control terminal can issue a control command to the submersible pump to control it to perform drainage.
[0018] According to the prefabricated water supply inspection well with flood prevention and leak detection function disclosed in this utility model, the outlet end of the submersible pump is provided with a drain pipe, and the outlet of the drain pipe leads to the outside of the bottom of the well. With the help of the drain pipe leading to the outside of the bottom of the well, the water accumulated in the sump can be easily discharged from the inspection well when the submersible pump is working.
[0019] According to the prefabricated water supply inspection well with flood prevention and leak detection function disclosed in this utility model, it also includes an information display terminal, which is connected to a control terminal to display the liquid level information and the cause of water ingress in the sump to the inspection personnel, so that the inspection personnel can decide whether to carry a portable submersible pump for drainage operation based on the displayed liquid level information.
[0020] The information display terminal can be a monitor integrated into the control terminal, a standalone monitor, or a mobile phone, PDA, or iPad carried by the inspection personnel. With the help of the information display terminal, inspection personnel can quickly and promptly understand the changes in the water level in the monitored manhole and the causes of water accumulation.
[0021] In contrast to the aforementioned scenario where a submersible pump is installed, in one embodiment, the submersible pump may not be installed in the sump. In this case, inspection personnel can carry a portable submersible pump to perform drainage operations based on the displayed information.
[0022] According to the prefabricated water supply inspection well with flood prevention and leak detection function disclosed in this utility model, it also includes a power supply device installed outside the well body and located on the ground. The power supply device can provide power to the solar power panel and / or the storage battery for the liquid level detector and the submersible pump.
[0023] According to the prefabricated water supply inspection well with flood prevention and leak detection function disclosed in this utility model, the well body includes a well cover, a well ring, and a well wall from top to bottom; the top of the well wall has a well wall socket groove to form an insertion fit with the well ring socket flange on the bottom of the well ring; the bottom of the well wall has a well wall socket flange to form an insertion fit with the well bottom socket groove on the top of the well bottom; the well cover can be laid flat on the upper opening of the well ring and connected to the well ring. The socket design, compared with the traditional inspection well installation method, makes on-site construction and installation, as well as later maintenance and replacement, easier.
[0024] According to the prefabricated water supply inspection well with flood prevention and leak detection function disclosed in this utility model, the top of the well ring is provided with a lifting buckle to facilitate subsequent disassembly and replacement; a pipe through hole for water supply pipe to pass through is provided radially on the side wall of the well bottom, and the pipe through hole is located above the bottom of the well bottom.
[0025] According to the prefabricated water supply inspection well with flood prevention and leak detection function disclosed in this utility model, a pad layer is provided on the bottom of the well to distribute the load. By providing a pad layer at the bottom of the well, the load can be effectively distributed, the foundation settlement can be reduced, and the inspection well can be protected.
[0026] According to the prefabricated water supply inspection well with flood prevention and leak detection function disclosed in this utility model, the well cover, well ring, well wall, and well bottom are all prefabricated components prefabricated in the factory. Compared with the cast-in-place construction method, the components are directly transported to the site for assembly after being produced in the factory, reducing on-site construction procedures, speeding up the construction progress, reducing material loss and construction waste during the construction process, improving resource utilization and environmental protection, and facilitating later maintenance and replacement.
[0027] Beneficial effects: In this invention, the inclined well bottom allows water to be transported to a sump at the bottom of the well. A level detector inside the well monitors the water level in real time. When the water level reaches a certain height, a pump automatically drains the water from the sump to the outside of the inspection well. Furthermore, because the level detector monitors changes in the water level in real time, inspection personnel can immediately detect any water accumulation in the inspection well, enabling them to promptly assess for leaks in the pipes.
[0028] Moreover, the well bottom and the well body of this utility model adopt a plug-in design. Compared with the traditional installation method of inspection wells, the plug-in connection is more convenient for on-site construction and installation as well as later maintenance and replacement.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

Figure 2 This is a cross-sectional schematic diagram of the prefabricated water supply inspection well of this utility model. Figure 3 This is an exploded view of the manhole cover, manhole ring, manhole wall, and manhole bottom of the inspection well of this utility model.
[0039] Combination Figures 1-3 As shown, this utility model discloses a prefabricated water supply inspection well with flood prevention and leak detection functions, including a well body and a well bottom 4 that is plugged into the well body to form an assembly. Because the well bottom 4 and the well body are assembled using a plug-in method, compared with the traditional inspection well installation method, it is easier to carry out on-site construction and installation, as well as subsequent maintenance and replacement. The specific components of the well body and the connection relationships between the components are shown below.
[0040] In such Figures 1-3In the illustrated embodiment, the well body includes a well cover 1, a well ring 2, and a well wall 3 from top to bottom. The top of the well wall 3 has a well wall socket groove 11 to form an insertion fit with the well ring socket flange 12 on the bottom of the well ring 2. The bottom of the well wall 3 has a well wall socket flange 13 to form an insertion fit with the well bottom socket groove 14 on the top of the well bottom 4. The well cover 1 can be laid flat on the upper opening of the well ring 2 and connected to the well ring 2. Compared with the traditional installation method of inspection wells, the socket connection is more convenient for on-site construction and installation as well as later maintenance and replacement.
[0041] In this invention, the term "insertion fit" refers to the ability of the corresponding socket flange to be inserted into the corresponding socket groove in a way that allows it to be accommodated.
[0042] The top of the well ring 2 is equipped with a lifting buckle for easy disassembly and replacement; the side wall of the well bottom 4 is provided with a pipe through hole 16 for the water supply pipe 15 to pass through in the radial direction, and the pipe through hole 16 is located above the bottom of the well bottom 4.
[0043] A cushion layer is installed at the bottom of well bottom 4 to distribute the load. By installing a cushion layer at the bottom of well bottom 4, the load can be effectively distributed, the foundation settlement can be reduced, and the inspection well can be protected.
[0044] In such Figures 1-3 In the illustrated embodiment, the manhole cover 1, manhole ring 2, manhole wall 3, and manhole bottom 4 are all prefabricated components precast in the factory. Compared with the cast-in-place construction method, the components are directly transported to the site for assembly after being produced in the factory, reducing on-site construction procedures, accelerating the construction progress, reducing material loss and construction waste during the construction process, improving resource utilization and environmental friendliness, and facilitating later maintenance and replacement.
[0045] Furthermore, in this invention, the inner surface 4-1 of the bottom of the well bottom 4 is set as an inclined surface, and a water collection pit 5 is provided at the lower position of the inclined surface on the bottom of the well bottom 4; inside the well bottom 4, above the water collection pit 5, a liquid level detector 6 is provided to monitor the liquid level in the water collection pit 5. That is, in this invention, the inner side of the bottom of the inspection well 4 is inclined.
[0046] That is, the bottom inner side of the inspection well 4 is inclined, which allows the water entering the inspection well to automatically flow to the lower position of the inner surface 4-1 of the bottom of the well 4 under its own gravity. Simultaneously, since a collection pit 5 is set at the lower position corresponding to the inclined surface inside the well 4, the water entering the inspection well automatically flows into the collection pit 5, realizing automatic collection of the water entering the inspection well. Furthermore, with the help of a level detector 6 installed inside the well 4 that can monitor the liquid level in the collection pit 5, the changes in the liquid level in the collection pit 5 can be monitored in real time, so that when the water level in the well 4 reaches a certain height, the water collected in the collection pit 5 is discharged. The specific implementation of this function is as follows:
[0047] In such Figures 1-3 In the illustrated embodiment, the tilt angle of the inclined surface is 1-3°. In a preferred embodiment, the tilt angle of the inclined surface is 1°, but in other embodiments, the tilt angle of the inclined surface can also be 2° or 3°.
[0048] In such Figures 1-3 The illustrated embodiment also includes an information alarm system, which comprises an alarm device and a control terminal. The alarm device is installed inside the well bottom 4. The alarm device is signal-connected to the liquid level detector 6 to obtain liquid level information in the sump 5. The control terminal is located outside the inspection well. The alarm device is signal-connected to the control terminal via remote signal transmission to transmit the liquid level information in the sump 5 received from the liquid level detector 6 to the control terminal. Based on whether it is raining at the current time and / or the liquid level information, the control terminal can determine the cause of the current water ingress into the inspection well.
[0049] With the help of an information alarm system, once water is collected in the sump 5, the liquid level information (or signal) within the sump 5 can be transmitted in real time to the control terminal. This allows the control terminal to determine the cause of water accumulation in the sump 5. In this invention, the control terminal is a remote control terminal, which can be a central controller or a computer, iPad, or other hardware processor with central data processing capabilities. The alarm device can be an existing signal transmission device, which establishes a signal connection with the control terminal via remote signal transmission.
[0050] After receiving the liquid level information transmitted from the alarm device, the control terminal can determine the cause of water ingress into the inspection well based on whether it is raining at the current time and the received liquid level information. Specifically, for example, if it is raining at the current time, the control terminal can determine that the cause of water ingress is an occasional external water discharge; if it is not raining at the current time, the control terminal can determine that the cause of water ingress is a leak caused by damage to the water supply pipe 15, thus enabling timely detection of pipe leakage.
[0051] In such Figures 1-3 In the illustrated embodiment, a submersible pump 7 is installed in the sump 5. The submersible pump 7 is signal-connected to a level detector 6, so that when the level detector 6 detects that the liquid level in the sump 5 exceeds a threshold, it sends a signal to activate the submersible pump 7 to perform drainage. By means of the connection between the submersible pump 7 and the level detector 6, when the level detector 6 detects that the liquid level in the sump 5 exceeds the threshold, the level detector 6 can directly send a control command to the submersible pump 7 to control it to perform drainage. This can be achieved by installing a controller (e.g., a CPU processor) on the level detector 6 or the submersible pump 7, which is prior art and will not be elaborated further here.
[0052] In such Figures 1-3 In the illustrated embodiment, the outlet of the submersible pump 7 is provided with a drain pipe 8, and the outlet of the drain pipe 8 leads to the outside of the well bottom 4. With the help of the drain pipe 8 leading to the outside of the well bottom 4, it is possible to easily drain the water accumulated in the sump 5 from the inspection well when the submersible pump 7 is working.
[0053] In such Figures 1-3 In the illustrated embodiment, an information display terminal is also included. This terminal is connected to the control terminal to display the liquid level information and the cause of water ingress in the sump 5 to the inspection personnel, enabling them to decide whether to carry a portable submersible pump 7 for drainage operations based on the displayed liquid level information. The information display terminal can be a display integrated into the control terminal, a standalone display, or a mobile phone, PDA, or iPad carried by the inspection personnel.
[0054] In such Figures 1-3 The embodiment shown also includes a power supply device disposed outside the well body and located on the ground, which can power the solar panel 9 and the battery 10 to power the level detector 6 and the submersible pump.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
