Description

Technical Field

[0001] This utility model relates to the technical field of water meter monitoring equipment, and in particular to a manhole cover structure with monitoring function. Background Technology

[0002] In the water industry, water meters need to be installed in surface wells. The advantage of surface wells is that they provide insulation, protecting mechanical water meters from freezing and cracking. To facilitate the monitoring of water meters in surface wells, meter reading concentrators are installed on the well covers to perform meter readings by monitoring the water meters inside the wells.

[0003] In use, existing manhole covers are mainly secured with bolts to the meter reading concentrator in order to closely monitor the water meters inside the surface wells.

[0004] However, when using bolts to fix the meter reading concentrator to the manhole cover, the installation method of the meter reading concentrator on the manhole cover is relatively complicated, which will cause inconvenience for the manhole cover maintenance personnel to disassemble, inspect and maintain the meter reading concentrator in the future, reducing the convenience of manhole cover maintenance in the later stage. Utility Model Content

[0005] The present invention aims to solve the problem that the installation method of the meter reading concentrator on the manhole cover is relatively complicated, which will cause inconvenience to the manhole cover maintenance personnel in the subsequent disassembly, inspection and maintenance of the meter reading concentrator, and reduce the convenience of manhole cover maintenance in the later stage.

[0006] Therefore, this utility model proposes a manhole cover structure with monitoring function. Two bolts are loosened and removed from the operating panel. The operating panel then drives the fixed sleeve plate to move downwards along the round rod, compressing the spring mounted on the round rod. This controls the downward movement of the clamping frame, allowing the concentrator inside the clamping frame to be removed for repair or replacement. When a new concentrator is placed into the clamping frame, the compressed spring, under its elastic action, moves the fixed sleeve plate mounted on the round rod upwards, and the clamping slot at the top of the clamping frame engages with the clamping block. Finally, two bolts passing through the operating panel and threadedly connected to the fixed column lock the operating panel in place. This allows for rapid replacement of the concentrator.

[0007] To achieve the above objectives, this utility model proposes a manhole cover structure with monitoring function, including a manhole cover device, wherein a monitoring device for monitoring water meters in surface wells is provided on the manhole cover device, and a clamping device for quick installation of the monitoring device is provided at the bottom end of the manhole cover device.

[0008] The manhole cover device includes a fixing component that is fixedly installed in a surface well, and a manhole cover component that is movably connected to the fixing component is provided inside the fixing component;

[0009] The monitoring device includes a concentrator installed inside the clamping device for monitoring water meters in surface wells, and a communication antenna is installed at the top of the well cover assembly, which is connected to the concentrator.

[0010] The clamping device includes a clamping component disposed below the manhole cover assembly for clamping and fixing the concentrator. The bottom end of the manhole cover assembly is provided with a driving component for driving the clamping component to clamp and fix the concentrator. A locking component is disposed inside the driving component.

[0011] In addition, the manhole cover structure with monitoring function proposed above in this application may also have the following additional technical features:

[0012] Specifically, the fixing component includes a base that is movably connected to the manhole cover assembly. The base has several mounting holes, and several support plates are fixedly installed on the top of the base.

[0013] Specifically, the manhole cover assembly includes a manhole cover body movably connected to the base, the top of the manhole cover body is provided with a breathable membrane for maintaining ventilation of the surface well, and there are two breathable membranes, and the bottom of the manhole cover body is fixedly installed with a locking block for cooperating with the clamping assembly.

[0014] Specifically, the clamping assembly includes a card frame disposed between two drive components, the top of the card frame having a card slot for engaging with a card block, and fixed sleeve plates fixedly installed at the front and rear ends of the card frame.

[0015] Specifically, the drive assembly includes a fixed frame fixedly installed at the bottom of the manhole cover body, and a round rod for sliding the fixed sleeve plate is fixedly installed inside the fixed frame.

[0016] Specifically, the left and right ends of the fixed frame are provided with long slots for the locking assembly to move up and down, and the rod body of the round rod is fitted with a spring for driving the card frame to clamp and fix the concentrator.

[0017] Specifically, the locking assembly includes a fixed post fixedly installed on the right end of the fixed sleeve plate, and an operating plate for driving the fixed post to move up and down is fixedly installed on the right end of the fixed post. The operating plate is provided with bolts for locking the operating plate.

[0018] Compared with the prior art, the beneficial effects of this application are as follows:

[0019] By incorporating clamping, driving, and locking components, the concentrator can be quickly replaced when necessary. Two bolts can be loosened from the operating panel, and the operating panel drives the fixing sleeve to move downwards along the round rod, compressing the spring mounted on the rod. This controls the downward movement of the clamping frame, allowing the concentrator to be removed. A new concentrator is then placed into the frame. The compressed spring, under its elastic force, moves the fixing sleeve upwards, engaging the top slot of the clamping frame with the locking block. Two bolts, threaded through the connection between the operating panel and the fixing column, lock the operating panel in place, enabling rapid concentrator replacement. This solves the problem of needing to bolt the concentrator to the bottom of the manhole cover, which hinders quick concentrator replacement. Attached Figure Description

Detailed Implementation

[0027] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0028] The following description, in conjunction with the accompanying drawings, describes a manhole cover structure with monitoring function according to an embodiment of the present invention.

[0029] like Figures 1-6 As shown, a manhole cover structure with monitoring function according to an embodiment of the present utility model may include a manhole cover device 100, a monitoring device 200 for monitoring water meters in wells on the manhole cover device 100, and a clamping device 300 for quick installation of the monitoring device 200 at the bottom end of the manhole cover device 100.

[0030] The manhole cover device 100 includes a fixing component 110 fixedly installed in the surface well, and a manhole cover component 120 for movable connection is provided in the fixing component 110. The monitoring device 200 includes a concentrator 210 for monitoring the water meter in the surface well, which is provided in the clamping device 300. A communication antenna 230 is provided at the top of the manhole cover component 120, and a connecting line 220 for connecting to the concentrator 210 is provided at the bottom of the communication antenna 230.

[0031] The clamping device 300 includes a clamping component 310 disposed below the manhole cover assembly 120 for clamping and fixing the concentrator 210, and a driving component 320 disposed at the bottom end of the manhole cover assembly 120 for driving the clamping component 310 to clamp and fix the concentrator 210. A locking component 330 is disposed inside the driving component 320.

[0032] In one embodiment of this utility model, such as Figure 2 and Figure 3As shown, the fixing component 110 includes a base 111 that is movably connected to the manhole cover component 120. The outer ring of the base 111 can be fixed to the road surface with cement to ensure that the base 111 is flat and firm. The inner ring is further divided into two parts, namely a ring and a hole. The difference from the traditional manhole cover is that there is an additional ring for waterproofing and drainage. During installation, no cement should be used at the drainage hole of the ring. The hole should have a certain depth so that the water inside the ring can reach the original soil and seep out. The circular plane has an inclination of about 2%, tilting towards the drainage hole; the inner side of the circular ring is raised and fitted with a waterproof gasket; this allows the raised part of the base 111 to form an interference fit with the raised part of the manhole cover assembly 120, achieving a waterproof effect; and the waterproof gasket can be replaced periodically; the base 111 has several mounting holes 112, which are arranged in a circumferential array on the base 111; several support plates 113 are fixedly installed at the top of the base 111, so the base 111 can be installed at the top of the surface well by using expansion screws through the mounting holes 112; thus, the fatigue strength of the base 111 can be increased by using the support plates 113.

[0033] Furthermore, the manhole cover assembly 120 includes a manhole cover body 121 movably connected to the base 111. The top of the manhole cover body 121 is provided with a breathable membrane 122 for maintaining ventilation of the surface well, and there are at least two breathable membranes 122, which are symmetrically distributed on the top of the manhole cover body 121. The breathable membranes 122 are used to ensure the gas pressure balance inside the well and prevent temperature changes from causing gas pressure changes, which could lead to deformation or tilting of the manhole cover. The bottom of the manhole cover body 121 is fixedly installed with a locking block 123 for cooperating with the clamping assembly 310.

[0034] In practical use, the concentrator 210 is used to collect and upload water meter readings and environmental information inside the well, such as temperature and humidity, water immersion, access control, and air pressure. Among them, the temperature and humidity, access control, and air pressure sensors are integrated into the well cover body 121; the water immersion sensor receives data uploaded by the water meter; in addition, the concentrator 210 is equipped with a rail-mounted lithium iron phosphate battery pack to power the concentrator 210 for communication. The well cover body 121 is equipped with a pull handle and an electronic door lock is installed between it and the base 111. Maintenance personnel can unlock the well cover body 121 through a mobile APP, and the APP software can trace the person who unlocked the door.

[0035] In one embodiment of this utility model, such as Figure 4 and Figure 5As shown, the clamping assembly 310 includes a frame 311 disposed between two drive assemblies 320. The frame 311 is located directly below the manhole cover body 121. The frame 311 is made of transparent material to facilitate the concentrator 210 located inside the frame 311 to monitor the water meter in the surface well. Therefore, the concentrator 210 can be clamped and fixed by the cooperation between the frame 311 and the manhole cover body 121. The top of the frame 311 is provided with a slot 312 for cooperating with the card block 123. Fixing sleeves 313 are fixedly installed at the front and rear ends of the frame 311.

[0036] Furthermore, the drive assembly 320 includes a fixed frame 321 fixedly installed at the bottom of the manhole cover body 121, wherein the fixed frame 321 is located on the front and rear sides of the frame 311; a round rod 323 for sliding the fixed sleeve 313 up and down is fixedly installed inside the fixed frame 321, wherein the round rod 323 is located inside the fixed frame 321; therefore, by using the fixed sleeve 313 to slide up and down on the round rod 323, the up and down movement of the frame 311 can be controlled, and thus the concentrator 210 can be fixed inside the frame 311.

[0037] Furthermore, the left and right ends of the fixed frame 321 are provided with long slots 322 for the fixed column 331 to move up and down, and the long slots 322 pass through the left and right ends of the fixed frame 321; the rod body of the round rod 323 is fitted with a spring 324 for driving the clamping frame 311 to clamp and fix the concentrator 210, wherein the spring 324 is located at the bottom end of the fixed sleeve plate 313, and the top end of the spring 324 is fixedly connected to the fixed sleeve plate 313, and the bottom end of the spring 324 is fixedly connected to the fixed frame 321; therefore, when the fixed sleeve plate 313 moves down along the round rod 323, the spring 324 fitted on the round rod 323 can be compressed.

[0038] Furthermore, the locking assembly 330 includes a fixing post 331 fixedly installed on the right end of the fixing sleeve 313, and the fixing post 331 can move up and down within the elongated groove 322; an operating plate 332 for driving the fixing post 331 to move up and down is fixedly installed on the right end of the fixing post 331, wherein the operating plate 332 is in close contact with the fixing frame 321; the plate body of the operating plate 332 is provided with bolts 333 for locking the operating plate 332, and there are two bolts 333, which are symmetrically distributed on the operating plate 332, wherein the two bolts 333 penetrate the operating plate 332 and are threadedly connected to the fixing frame 321, thereby locking the operating plate 332; therefore, by loosening and removing the two bolts 333 from the operating plate 332, the fixing post 331 can be controlled to move up and down within the elongated groove 322 by the operating plate 332. Moving downwards drives the fixed sleeve 313 to move downwards along the round rod 323, which in turn controls the frame 311 to move downwards until the concentrator 210 inside the frame 311 can be removed. Then, the connection between the concentrator 210 and the connecting line 220 is released, and the concentrator 210 can be removed from the frame 311. At the same time, the fixed sleeve 313 can compress the spring 324 mounted on the round rod 323. When the new concentrator 210 is placed into the frame 311, the compressed spring 324, under its elastic action, can move the fixed sleeve 313 mounted on the round rod 323 upwards, and can lock the top slot 312 of the frame 311 onto the block 123. Finally, by threading two bolts 333 through the operating plate 332 and connecting them to the fixed frame 321, the operating plate 332 can be locked.

[0039] In summary, the manhole cover structure with monitoring function of this utility model embodiment allows for the replacement of the concentrator 210 when the manhole cover body 121 is opened around the base 111, with the back of the manhole cover body 121 facing upwards. Then, the two bolts 333 are loosened and removed from the operating plate 332. The operating plate 332 then controls the fixed column 331 to move downwards within the long groove 322. The operating plate 332 is connected to the fixed sleeve plate 313 via the fixed connection of the fixed column 331, thus driving the fixed sleeve plate 313 to move downwards along the round rod 323. This controls the downward movement of the retaining frame 311 located below the manhole cover body 121 until the concentrator 210 can be removed from the retaining frame 311. Finally, the connection between the concentrator 210 and the connecting line 220 is released, allowing the concentrator 210 to be removed. 10. Remove the device from the frame 311; simultaneously, as the fixing plate 313 moves downward, it compresses the spring 324 mounted on the round rod 323. Then, place the new concentrator 210 into the frame 311 and release the force on the operating plate 332. At this time, the compressed spring 324, under its elastic action, can cause the fixing plate 313 mounted on the round rod 323 to move upward and lock the top slot 312 of the frame 311 into the locking block 123, thereby sealing the frame 311. Then, by using two bolts 333 to pass through the operating plate 332 and connect with the threaded connection between them and the fixing frame 321, the operating plate 332 can be locked. This allows for the quick replacement of the concentrator 210 in the frame 311, thus solving the problem of inconvenience in repairing and replacing the concentrator 210.

[0040] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
