Rural sewage pipeline detection device

Abstract

This utility model discloses a rural sewage pipeline testing device, belonging to the field of pipeline testing. It aims to solve the problem of insufficient fit in existing technologies where the outer curvature of pipes of different specifications varies. Existing pressure plates, typically of a fixed shape, cannot fully conform to the outer curved surfaces of pipes of different specifications. This insufficient fit leads to uneven pressure application to the outer side of the pipe when applying pressure to pipes of different specifications. Some areas may experience excessive pressure while others receive insufficient pressure, affecting the accuracy of the test results and potentially causing unnecessary damage to the pipe due to excessive local pressure. This results in biased test information that fails to accurately reflect the pressure resistance of the pipeline. The device includes a water tank with a cover at the top. A rural sewage pipeline is installed inside the tank, along with a fixing mechanism. Testing mechanisms are located at both the inner and outer ends of the tank.

Description

Technical Field

[0001] This utility model belongs to the field of pipeline inspection, specifically relating to a rural sewage pipeline inspection device. Background Technology

[0002] In the manufacturing and use of rural sewage pipes, the pressure resistance of the pipes is one of the key indicators to ensure their safe operation. Currently, when testing the pressure resistance of pipes, a pressure plate connected to a pressure sensor is often used to conduct a compression test on the pipe. This method applies pressure to the outside of the pipe through the pressure plate and uses the pressure sensor to monitor the pressure data in real time, thereby determining the pressure resistance of the pipe.

[0003] However, because the outer curvature of pipes of different specifications varies, existing pressure plates are usually of a fixed shape, making it difficult to perfectly fit the outer curved surface of pipes of different specifications. This insufficient fit means that when pressurizing pipes of different specifications, it is impossible to ensure that the pressure is applied evenly to the outer side of the pipe. Some areas may be subjected to excessive pressure, while other areas may be subjected to insufficient pressure. This not only affects the accuracy of the test results but may also cause unnecessary damage to the pipe due to excessive local pressure, resulting in biased test results that cannot truly reflect the pressure resistance performance of the pipe. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a rural sewage pipeline testing device. This device aims to solve the problem that existing pressure plates, typically of a fixed shape, cannot fully conform to the outer curvature of pipes of different specifications due to varying outer arcs. This insufficient fit results in uneven pressure application to the outer surface of pipes of different specifications. Some areas may experience excessive pressure while others receive insufficient pressure, affecting the accuracy of the test results and potentially causing unnecessary damage to the pipeline due to localized excessive pressure. This leads to biased test results that fail to accurately reflect the pipeline's pressure resistance.

[0007] To solve the above-mentioned technical problems, this utility model provides a rural sewage pipeline testing device, including a water tank, a tank cover connected to the upper end of the water tank, a rural sewage pipeline installed inside the water tank, a fixing mechanism installed inside the water tank, and testing mechanisms installed at both the inner and outer ends of the water tank. The testing mechanism includes a pressure plate connected to the inner side of the water tank, limit rods welded to the four corners of the bottom side of the water tank, a hydraulic cylinder installed at the middle position of the upper side of the tank cover, a pressure gauge installed at the front end of the water tank, a lower semi-cylinder fixedly connected to the middle position of the upper front side of the water tank, a circular plate fixedly connected to the front side of the lower semi-cylinder, springs fixedly connected at equal intervals at the rear edge of the circular plate, a positioning ring fixedly connected to the rear end of the springs, and an upper semi-cylinder fixedly connected to the middle position of the front side of the tank cover.

[0008] Furthermore, the fixing mechanism includes threaded posts fixedly connected to the lower left and right ends of the inner side of the water tank, a sleeve rod connected to the outer side of the threaded post, a lever fixedly connected to the front and rear ends of the outer side of the sleeve rod, and a fixing plate fixedly connected to the side of the sleeve rod away from the threaded post.

[0009] Furthermore, the pressure plate has vertically extending limiting holes at its four corners, the outer side of the limiting rod is slidably connected to the inner side of the limiting hole, and the outer perimeter of the pressure plate is slidably connected to the inner side of the water tank.

[0010] Furthermore, the upper rear end of the water tank is hinged to the rear end of the tank cover, the lower inner end of the positioning ring is slidably connected to the arc-shaped surface of the outer side of the lower semi-cylinder, the upper inner end of the positioning ring is slidably connected to the arc-shaped surface of the outer side of the upper semi-cylinder, and the upper side of the lower semi-cylinder abuts against the lower side of the upper semi-cylinder.

[0011] Furthermore, the lower end of the output shaft of the hydraulic cylinder abuts against the upper middle position of the pressure plate, the water tank is filled with hydraulic oil, and the detection end of the pressure gauge is located at the lower end of the inside of the water tank.

[0012] Furthermore, the sleeve has an internal thread, and the outer side of the threaded post is threadedly connected to the inner side of the sleeve.

[0013] Furthermore, the side of the fixing plate furthest from the sleeve rod abuts against the left and right sides of the sewage pipe.

[0014] Furthermore, rubber pads are fixedly connected to the side of the fixing plate away from the sleeve rod, as well as to the front, rear, left, and right sides of the pressure plate, and rubber rings are fixedly connected to the inner side of the limiting hole inside the pressure plate.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention, through the setting of a detection mechanism, after the tank cover is fixed to the upper side of the water tank, the hydraulic cylinder is activated. When its output shaft extends and pushes down the pressure plate, the pressure plate also applies pressure to the hydraulic oil under the pressure plate inside the water tank. This causes the hydraulic oil to squeeze the sewage pipe inside, allowing the hydraulic oil to transmit pressure evenly to the surface of the pipe. Regardless of the shape of the pipe, the pressure on all parts of the outer surface is equal, resulting in a more uniform pressure distribution and ensuring the accuracy of the pressure resistance test results.

[0018] This utility model, by setting a fixing mechanism, allows the sewage pipe to be tested to be placed between the fixing plates inside the water tank. Then, the lever is moved to rotate the sleeve rod outside the threaded column, causing the sleeve rod and fixing plate to move until the fixing plates at both ends move to abut against the left and right sides of the sewage pipe. This clamps and fixes the sewage pipe between the fixing plates. The adjustable fixing plates can also clamp and fix sewage pipes of different sizes between the fixing plates inside the water tank.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] This specific embodiment is a rural sewage pipeline inspection device, and its structural schematic diagram is shown below. Figures 1 to 4 As shown, the system includes a water tank 1, with a cover 2 connected to the upper end of the water tank 1. A rural sewage pipe 3 is installed inside the water tank 1. A fixing mechanism is installed inside the water tank 1, including threaded posts 401 fixedly connected to the lower left and right ends of the inner side of the water tank 1. A sleeve rod 402 is connected to the outer side of the threaded posts 401, and the sleeve rod 402 has internal threads. The outer side of the threaded posts 401 is threadedly connected to the inner side of the sleeve rod 402. A lever 403 is fixedly connected to the front and rear ends of the outer side of the sleeve rod 402. A fixing plate 404 is fixedly connected to the side of the sleeve rod 402 away from the threaded posts 401. The side of the fixing plate 404 away from the sleeve rod 402 abuts against the left and right sides of the sewage pipe 3. After placing the sewage pipe 3 to be tested between the fixing plates 404 inside the water tank 1, the lever 403 is then turned so that the sleeve 402 rotates outside the threaded column 401, causing the sleeve 402 and the fixing plate 404 to move until the fixing plates 404 at both ends move to abut against the left and right sides of the sewage pipe 3. The sewage pipe 3 can then be clamped and fixed between the fixing plates 404. The fixing plates 404 at both ends of the sewage pipe 3 can also close both ends of the sewage pipe 3. The adjustable fixing plates 404 can also clamp and fix sewage pipes 3 of different sizes between the fixing plates 404 inside the water tank 1.

[0028] Rubber pads are fixedly connected to the side of the fixing plate 404 away from the sleeve rod 402, and to the front, rear, left, and right sides of the pressure plate 501. A rubber ring is fixedly connected to the inner side of the limiting hole inside the pressure plate 501. This ensures that the contact points between the pressure plate 501 and the water tank 1 and the limiting rod 502 are sealed, and the contact points between the left and right ends of the sewage pipe 3 and the fixing plate 404 are sealed, thereby ensuring that the hydraulic oil in the water tank 1 will not seep into the sewage pipe 3, nor will it seep into the pressure plate 501.

[0029] match Figure 5As shown, detection mechanisms are provided at both the inner and outer ends of the water tank 1. Each detection mechanism includes a pressure plate 501 connected to the inner side of the water tank 1. Limiting rods 502 are welded to the four corners of the bottom side of the water tank 1. Limiting holes extending vertically are provided at the four corners of the inner side of the pressure plate 501. The outer side of the limiting rods 502 is slidably connected to the inner side of the limiting holes, and the outer perimeter of the pressure plate 501 is slidably connected to the inner side of the water tank 1. Therefore, when the pressure plate 501 moves, it can only slide along the outer side of the limiting rods 502 within the water tank 1, thus limiting the movement of the pressure plate 501.

[0030] A hydraulic cylinder 503 is installed at the middle of the upper side of the tank cover 2. A pressure gauge 504 is installed at the front end of the water tank 1. A lower semi-cylinder 505 is fixedly connected to the middle of the upper front side of the water tank 1. A circular plate 506 is fixedly connected to the front side of the lower semi-cylinder 505. Springs 507 are fixedly connected at equal intervals along the rear edge of the circular plate 506. A positioning ring 508 is fixedly connected to the rear end of the springs 507. An upper semi-cylinder 509 is fixedly connected to the middle of the front side of the tank cover 2. The upper rear side of the water tank 1 is hinged to the rear side of the tank cover 2. The lower inner side of the positioning ring 508 is slidably connected to the arc-shaped surface of the lower semi-cylinder 505. The upper inner side of the positioning ring 508 is slidably connected to the arc-shaped surface of the upper semi-cylinder 509. The upper side of the lower semi-cylinder 505 abuts against the lower side of the upper semi-cylinder 509. By compressing the spring 507 through the forward positioning ring 508, the tank cover 2 is rotated to the upper side of the water tank 1. At the same time, the upper semi-cylinder 509 moves to the upper side of the lower semi-cylinder 505, and then the positioning ring 508 is released. After the spring 507 rebounds, it pushes the positioning ring 508, pushing the positioning ring 508 to the outside of the lower semi-cylinder 505 and the upper semi-cylinder 509. This allows the lower semi-cylinder 505 and the upper semi-cylinder 509 to be relatively fixed to the inside of the positioning ring 508, thereby fixing the tank cover 2 to the upper end of the water tank 1.

[0031] Furthermore, the lower end of the output shaft of the hydraulic cylinder 503 abuts against the upper middle position of the pressure plate 501. The water tank 1 is filled with hydraulic oil, and the detection end of the pressure gauge 504 is located at the lower end of the inside of the water tank 1. Thus, after the tank cover 2 is fixed to the upper side of the water tank 1, when the hydraulic cylinder 503 is started, its output shaft extends and pushes down the pressure plate 501. At the same time, the pressure plate 501 also applies pressure to the hydraulic oil below the pressure plate 501 inside the water tank 1. In turn, the hydraulic oil squeezes the sewage pipe 3 inside, so that the hydraulic oil can transmit pressure evenly to the surface of the pipe. Regardless of the shape of the pipe, the pressure on all parts of the outer surface is equal, so the pressure distribution is more uniform and the accuracy of the pressure resistance test results is guaranteed.

[0032] Working principle: When performing a pressure test on the sewage pipe 3, the sewage pipe 3 to be tested is first placed between the fixed plates 404 inside the water tank 1. Then, the lever 403 is moved so that the sleeve 402 rotates outside the threaded column 401, causing the sleeve 402 and the fixed plate 404 to move until the fixed plates 404 at both ends move to abut against the left and right sides of the sewage pipe 3, clamping and fixing the sewage pipe 3 between the fixed plates 404. Then, hydraulic oil is poured into the water tank 1, and the pressure plate 501 is slid to the inside of the water tank 1 and passes through the limit rod 502. Then, the tank cover 2 is rotated to the top of the water tank 1 and fixed. Finally, the hydraulic cylinder 503 is started, and its output shaft extends. When the pressure plate 501 is pushed down, the pressure plate 501 also applies pressure to the hydraulic oil below the pressure plate 501 inside the water tank 1. The hydraulic oil then squeezes the surface of the sewage pipe 3 inside, performing the pressure test on the sewage pipe 3.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
