Technical Field

[0001] This utility model relates to the field of inspection well technology, specifically to an integral precast concrete inspection well for power applications. Background Technology

[0002] Inspection wells are designed to facilitate the maintenance and installation of underground infrastructure such as power supply, water supply, drainage, sewage, communications, cable TV, gas pipes, and street light lines in cities. They are generally located at pipe junctions, bends, changes in pipe diameter or slope, and at regular intervals on straight pipe sections. They are well-shaped structures made of one-piece injection-molded plastic or brick for the purpose of facilitating regular inspection, cleaning, dredging, or access operations.

[0003] According to the search, a patent publication number CN221030319U for an integral precast concrete inspection well for power use was published in China on May 28, 2024. It is roughly described as including a well body, a well opening at the top of the well body, a wire hole on the side wall of the well body, a drain pipe fixedly installed at the bottom of the well body, a grating plate on the upper side of the drain pipe, and a guide plate on the outer side of the grating plate.

[0004] While the aforementioned existing technical solutions can prevent garbage from entering the drain pipe and reduce pipe blockage, the device makes it inconvenient to remove the grating plate, which in turn makes it difficult to clean up the garbage and reduces work efficiency. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an integral precast concrete inspection well for power applications, thereby solving the problem mentioned in the background technology that makes it inconvenient to clean up garbage and reduces work efficiency.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a precast concrete manhole for power applications, comprising a manhole body, a support frame, two sliding openings on the support frame, a manhole opening at the top of the manhole body, a discharge outlet at the bottom of the manhole body, a drain pipe fixedly connected to the bottom of the manhole body to cooperate with the discharge outlet, a receiving groove on the inner lower side wall of the manhole body to cooperate with the discharge outlet, the support frame placed inside the receiving groove, two limiting rods fixedly connected to the inner lower side wall of the receiving groove to cooperate with the sliding openings, and a retaining rod placed on the support frame. The top of the screen frame is lower than the top of the receiving tank. The top of the support frame is provided with two lifting rings. The top of the well body is fixedly connected to a connecting frame. A rope wheel is rotatably connected inside the connecting frame. A lifting rope is wound around the rope wheel. The bottom of the lifting rope is provided with two forked ropes. The bottom ends of the two forked ropes are respectively connected to two lifting rings. One end of the rope wheel passes through the connecting frame and is connected to a first sprocket. A second sprocket is rotatably connected to the outer wall of the connecting frame. A chain is connected between the second sprocket and the first sprocket. A servo motor connected to the second sprocket is installed at the top of the well body.

[0009] By adopting the above technical solution, the filter screen frame is used to block and filter garbage falling into the drain pipe, preventing larger garbage from falling into the drain pipe and thus reducing the probability of drain pipe blockage. When it is necessary to clean the garbage in the filter screen frame, the servo motor is started to drive the second sprocket to rotate. The second sprocket drives the first sprocket to rotate through the chain. The first sprocket drives the rope wheel to rotate. The rope wheel winds up the lifting rope. The lifting rope drives the support frame to move along the limit rod through two forked ropes and two lifting rings. At this time, the support frame drives the screen frame to move. When the support frame moves to the top, the screen frame can be removed along the top of the two limit rods. This makes it easy to dump the garbage in the screen frame and to clean the screen frame itself. After cleaning, the filter screen frame is placed on the support frame. At this time, the servo motor is started to rotate in the opposite direction, so that the rope wheel releases the lifting rope, so that the support frame and the filter screen frame move downwards, thus putting the filter screen frame back into the drain pipe. This achieves the purpose of facilitating garbage cleaning and improving work efficiency.

[0010] Optionally, the lower inner sidewall of the well body is provided with an inclined guide that matches the discharge port.

[0011] By adopting the above technical solution, the inclined guide component is used to guide water and garbage in the well to the discharge outlet, thereby reducing the residue of water and garbage in the well.

[0012] Optionally, each of the two limiting rods has two corresponding limiting grooves, and each of the two sliding ports has two guide pulleys rotatably connected to its inner sidewall. The four guide pulleys are respectively attached to the inner sidewall of the four limiting grooves.

[0013] By adopting the above technical solution, the guide pulley and the limiting groove cooperate to reduce the friction between the support frame and the limiting rod, thereby facilitating the traction rope to pull the support frame and reducing the load on the servo motor.

[0014] Optionally, two slots are provided at the top of the well body, and ladders are inserted into the two slots, with the bottom of the ladders close to the inner lower side wall of the well body.

[0015] By adopting the above technical solution, the ladder is used to facilitate personnel climbing, thereby facilitating personnel to enter and exit the well. The slot is used to position the ladder, making it easy to pick up and put down, and thus facilitating the replacement of the ladder when it is damaged or corroded.

[0016] Optionally, the ladder has two cooperating support rods fixedly connected to one end near the inner wall of the well body. One end of each support rod is tightly attached to the inner wall of the well body. Two U-shaped positioning parts that cooperate with the two support rods are fixedly connected to the inner wall of the well body.

[0017] By adopting the above technical solution, the support rod is used to support the bottom of the ladder, and the U-shaped positioning component is used to position the support rod to prevent it from tilting, thereby preventing the ladder from tilting and swaying, thus improving the safety of the equipment.

[0018] (III) Beneficial Effects

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] This power plant uses a precast concrete manhole with a filter screen to block and filter debris falling into the drain pipe, preventing larger pieces from entering and reducing the likelihood of blockage. When cleaning the filter screen, a servo motor drives a second sprocket, which in turn drives a first sprocket via a chain. The first sprocket then drives a rope wheel, which winds up a lifting rope. This rope, through two branch ropes and two lifting rings, moves a support frame along a limit bar, causing the support frame to pass through a screen. The screen frame moves, and when the support frame reaches the top, the screen frame can be removed along the top of the two limit rods. This facilitates the dumping of waste from the screen frame and the cleaning of the screen frame itself. After cleaning, the filter frame is placed on the support frame, and the servo motor is started to rotate in reverse, causing the rope wheel to release the lifting rope. This moves the support frame and filter frame downwards, allowing the filter frame to be placed back into the drain pipe. This facilitates waste cleaning and improves work efficiency.

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

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Reference Figures 1-5A precast concrete manhole for power applications includes a manhole body 1, a support frame 2 with two sliding openings, a manhole opening at the top of the manhole body 1, a discharge outlet at the bottom of the manhole body 1, a drain pipe 3 fixedly connected to the bottom of the manhole body 1 to mate with the discharge outlet, a receiving groove on the inner lower side wall of the manhole body 1 to mate with the discharge outlet, the support frame 2 placed inside the receiving groove, two limiting rods 4 fixedly connected to the inner lower side wall of the receiving groove to mate with the sliding openings, and a screen frame 5 placed on the support frame 2, the top of the screen frame 5 being lower than the receiving groove. At the top, the support frame 2 has two lifting rings 6. The top of the well body 1 is fixedly connected to a connecting frame 7. A rope wheel 8 is rotatably connected inside the connecting frame 7. A lifting rope 9 is wound around the rope wheel 8. The bottom end of the lifting rope 9 has two forked ropes 10. The bottom ends of the two forked ropes 10 are respectively connected to the two lifting rings 6. One end of the rope wheel 8 passes through the connecting frame 7 and is connected to a first sprocket 11. A second sprocket 12 is rotatably connected to the outer wall of the connecting frame 7. A chain 13 is drivingly connected between the second sprocket 12 and the first sprocket 11. The top of the well body 1 is installed with a part connected to the second sprocket 12. The servo motor 14 and the filter screen are used to filter and block debris falling into the drain pipe 3, preventing larger debris from falling into the drain pipe 3 and thus reducing the probability of blockage. When it is necessary to clean the debris in the filter screen, the servo motor 14 is started to drive the second sprocket 12 to rotate. The second sprocket 12 drives the first sprocket 11 to rotate via the chain 13. The first sprocket 11 drives the rope wheel 8 to rotate. The rope wheel 8 winds up the lifting rope 9. The lifting rope 9 drives the support frame 2 to move along the limit rod 4 via two forked ropes 10 and two lifting rings 6. At this time, the support frame 2 drives the... The screen frame 5 moves, and when the support frame 2 moves to the top, the screen frame 5 can be removed along the top of the two limit rods 4. This makes it easy to dump the garbage in the screen frame 5 and to clean the screen frame 5 itself. After cleaning, the filter screen frame is placed on the support frame 2. At this time, the servo motor 14 is started to rotate in reverse, so that the rope wheel 8 releases the lifting rope 9, thereby moving the support frame 2 and the filter screen frame downward, so that the filter screen frame is put back into the drain pipe 3. This achieves the purpose of facilitating garbage cleaning and improving work efficiency.

[0032] Reference Figure 3 and Figure 5 The lower inner side wall of the well body 1 is provided with an inclined guide 15 that cooperates with the discharge port. The inclined guide 15 is used to guide the water and garbage in the well body 1 to the location of the discharge port, thereby reducing the residue of water and garbage in the well body 1.

[0033] Reference Figure 5 and Figure 6Each of the two limiting rods 4 has two corresponding limiting grooves 16. Each of the two sliding ports has two guide pulleys 17 rotatably connected to its inner sidewall. The four guide pulleys 17 are respectively close to the inner sidewall of the four limiting grooves 16. The guide pulleys 17 cooperate with the limiting grooves 16 to reduce the friction between the support frame 2 and the limiting rods 4, thereby facilitating the traction rope to pull the support frame 2 and reducing the load on the servo motor 14.

[0034] Reference Figures 2-6 Two slots 18 are provided at the top of the well body 1. A ladder 19 is inserted into the two slots 18. The bottom of the ladder 19 is close to the inner lower side wall of the well body 1. The ladder 19 is used to facilitate personnel to climb and enter and exit the well body 1. The slots 18 are used to position the ladder 19 and facilitate the removal and placement of the ladder 19. This makes it easy to replace the ladder 19 if it is damaged or corroded.

[0035] Reference Figure 5 and Figure 7 The ladder 19 has two cooperating support rods 20 fixedly connected at one end near the inner wall of the well body 1. One end of each support rod 20 is tightly attached to the inner wall of the well body 1. Two U-shaped positioning parts 21 are fixedly connected to the inner wall of the well body 1, which respectively cooperate with the two support rods 20. The support rods 20 are used to support the bottom of the ladder 19, and the U-shaped positioning parts 21 are used to position the support rods 20 to prevent them from tilting, thereby preventing the ladder 19 from tilting and shaking, thus improving the safety of the equipment.

[0036] It should be further explained that the servo motor 14 in this embodiment is a conventional device known to those skilled in the art and available on the market. The model can be selected or customized according to actual needs. In this patent, we only use it without improving its structure and function. Its setting method, installation method and electrical connection method can be debugged and operated by those skilled in the art according to the requirements of its instruction manual. It will not be described in detail here. The servo motor 14 is equipped with a matching control switch. The installation position of the control switch can be selected according to the actual use requirements to facilitate the operator's operation and control.

[0037] In summary, the working principle and process of this precast concrete inspection well for power applications are as follows: During use, the filter screen first filters out debris falling into the drain pipe 3, preventing larger debris from entering and reducing the probability of blockage. When cleaning the debris from the filter screen is required, the servo motor 14 is activated, driving the second sprocket 12 to rotate. The second sprocket 12, through the chain 13, drives the first sprocket 11 to rotate, which in turn drives the rope pulley 8 to rotate. The rope pulley 8 then pulls the lifting rope... 9. The lifting rope 9, via two forked ropes 10 and two lifting rings 6, drives the support frame 2 to move along the limiting rod 4. At this time, the support frame 2 drives the screen frame 5 to move. When the support frame 2 reaches the top, the screen frame 5 can be removed along the top of the two limiting rods 4. This facilitates the emptying of waste from the screen frame 5 and the cleaning of the screen frame 5 itself. After cleaning, the filter frame is placed on the support frame 2. Then, the servo motor 14 is started to rotate in reverse, causing the rope wheel 8 to lift... Rope 9 is released, causing the support frame 2 and filter screen frame to move downwards, thus placing the filter screen frame back into the drain pipe 3. This facilitates garbage removal and improves work efficiency. The inclined guide 15 guides water and garbage in the well body 1 to the discharge outlet, reducing water and garbage residue in the well body 1. The guide pulley 17 cooperates with the limiting groove 16 to reduce the friction between the support frame 2 and the limiting rod 4, thereby facilitating the pulling of the support frame 2 by the traction rope and reducing the friction of the servo motor 1. 4. The ladder 19 is designed to facilitate personnel climbing and access to and from the well body 1. The slot 18 is used to position the ladder 19 for easy access and replacement. This facilitates replacement of the ladder 19 if it is damaged or corroded. The support rod 20 is used to support the bottom of the ladder 19. The U-shaped positioning part 21 is used to position the support rod 20 to prevent it from tilting, thus preventing the ladder 19 from tilting or swaying and improving equipment safety.

[0038] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
