Description

A multi-probe telescopic device for rapid detection of leakage in water conservancy projects Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically a multi-probe telescopic device for rapid detection of leakage in water conservancy projects. Background Technology

[0002] Water conservancy projects refer to various projects constructed to prevent water-related disasters and rationally develop and utilize water resources. These projects cover multiple aspects, including flood control, drainage, irrigation, water supply, hydropower generation, navigation, water resource protection, and soil and water conservation. Water conservancy project construction involves laying water pipes underground. Water pipes buried underground for many years inevitably age and break down. After damage, water pipes will leak, affecting the water supply and drainage effect, thus requiring inspection by illumination.

[0003] Existing rapid leak detection methods for water conservancy projects employ a telescopic rod that can be extended and spliced. A probe is installed at the end of the rod and extends into the pipe to inspect the entire pipeline. However, since the pipeline is long, continuously splicing the telescopic rod requires a large amount of material, increasing costs. Furthermore, the constant pushing and pushing increases manual labor and is not practical. In some areas, when water pipes are repaired, the entire pipeline is dug up for more direct inspection. This inspection method involves a huge amount of work, requiring even more time and money, and is even less effective for detecting leaks in water pipes.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a multi-probe telescopic device for rapid detection of leakage in water conservancy projects. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-probe telescopic device for rapid detection of leakage in water conservancy projects, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-probe telescopic device for rapid detection of leakage in water conservancy projects, comprising a connecting cylinder, with a covering cylinder fixedly connected to both the left and right ends of the connecting cylinder, and the same electric telescopic rod fixedly connected to the outer surface of the covering cylinder on both facing sides, and a bidirectional lead screw rotatably connected to the inner surface of the covering cylinder, with threaded sleeves threadedly connected to both the left and right sides of the surface of the bidirectional lead screw, and movable rods rotatably connected to the circumference of the surface of the threaded sleeves, and the ends of the corresponding movable rods on the threaded sleeves of the same bidirectional lead screw surface penetrating the covering cylinder, and a support plate rotatably connected by the same bearing.

[0007] Preferably, four electric telescopic rods are evenly distributed around the circumference, and the electric telescopic rods are located inside the connecting cylinder.

[0008] Preferably, the support plate consists of a plate body and a rubber sleeve covering the surface of the plate body, and the plate body of the support plate is set to be arc-shaped.

[0009] Preferably, a drive motor is fixedly installed on the right side of the outer surface of the covering cylinder, and the rotating shaft of the drive motor passes through the covering cylinder and is connected to a bidirectional lead screw.

[0010] Preferably, light strips are fixedly connected to both the left and right sides of the outer surface of the connecting cylinder, and four cameras are fixedly connected to the center of the surface of the connecting cylinder in a circumferentially even distribution.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the arrangement of a covering cylinder, an electric telescopic rod, a double-acting screw, a threaded sleeve, a movable rod, and a support plate, integrates the entire device into the pipeline structure. First, the right-side double-acting screw is rotated. As the screw rotates, the threaded sleeve moves in opposite directions, causing the movable rod to carry the support plate outwards and push it up. The support plate then adheres tightly to the inner surface of the pipeline, thus centrally fixing and supporting the entire device. Next, the electric telescopic rod extends, pushing the left-side covering cylinder forward. When it reaches its maximum position, the left-side double-acting screw rotates, using the same steps to firmly fix the support plate to the pipeline. Then, the right-side double-acting screw reverses... Rotate the support plate to detach it from the inner surface of the pipe, thus releasing the right-side covering cylinder from its fixation. At this point, the electric telescopic rod retracts. Since the left-side covering cylinder is fixed, the electric telescopic rod will drive the right-side covering cylinder to move to the left when it retracts. By continuously repeating the above steps, the device can automatically crawl and move inside the pipe, thereby performing a comprehensive mobile inspection of the pipe without the need for manual assistance. The entire device moves automatically, resulting in higher inspection efficiency. Furthermore, the expansion-type fixation of the support plate allows for flexible adaptation to different pipe sizes, thus enabling crawling inspection of pipes of various diameters.

[0013] 2. This utility model, through the setting of light strips and cameras, allows four cameras to cover all surfaces inside the pipe, thus completely illuminating the entire inner surface of the pipe for inspection. The cameras can move with the covering cylinder using the connecting tube, thereby illuminating and inspecting the entire pipe. Furthermore, the light strips can supplement the lighting of the cameras, ensuring clear detection even when inserted into the pipe. Attached Figure Description

[0018] 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.

[0019] As shown in Figures 1-3, a multi-probe telescopic device for rapid detection of leakage in water conservancy projects includes a connecting cylinder 1. Both ends of the connecting cylinder 1 are fixedly connected to a covering cylinder 2. The outer surfaces of the covering cylinder 2 are fixedly connected to the same electric telescopic rod 3 on opposite sides. The inner surfaces of the covering cylinder 2 are rotatably connected to a bidirectional lead screw 4. The left and right sides of the surface of the bidirectional lead screw 4 are threadedly connected to threaded sleeves 5. The four sides of the surface of the threaded sleeves 5 are rotatably connected to movable rods 6. The ends of the left and right movable rods 6 on the threaded sleeves 5 on the same surface of the bidirectional lead screw 4 penetrate the covering cylinder 2 and are rotatably connected to a support plate 7 using the same bearing.

[0020] Four electric telescopic rods 3 are evenly distributed around the circumference, and the electric telescopic rods 3 are located inside the connecting cylinder 1;

[0021] A positioner can be installed on the surface of the connecting cylinder 1.

[0022] By adopting the above technical solution, the right double-acting screw 4 is rotated. When the double-acting screw 4 rotates, the threaded sleeve 5 moves in opposite directions, causing the movable rod 6 to carry the support plate 7 to bulge outward and push it up. The support plate 7 is in close contact with the inner surface of the pipe, thereby centrally fixing and supporting the entire device.

[0023] When the electric telescopic rod 3 extends, it pushes the left-side covering cylinder 2 forward. When it reaches the maximum position, the left-side bidirectional screw 4 rotates, and the same steps are used to make the support plate 7 tightly attached to the pipe. Then the right-side bidirectional screw 4 reverses, causing the support plate 7 to detach from the inner surface of the pipe, that is, the right-side covering cylinder 2 is released from fixation. At this time, the electric telescopic rod 3 retracts. Since the left-side covering cylinder 2 is fixed, when the electric telescopic rod 3 retracts, it will drive the right-side covering cylinder 2 to move to the left. By continuously repeating the above steps, the device can automatically crawl and move inside the pipe.

[0024] The support plate 7 is expandable and can be flexibly adapted to the size of the pipe;

[0025] A locator is installed on the surface of the connecting cylinder 1. The locator can be used to determine the position of the entire device in the pipeline. That is, after the leak is detected, the pipeline can be dug directly from the corresponding position on the ground for repair, thus avoiding the need to dig out the entire pipeline. The precise location of the excavation not only reduces the amount of work but also improves maintenance efficiency.

[0026] Furthermore, the support plate 7 consists of a plate body and a rubber sleeve covering the surface of the plate body, and the plate body of the support plate 7 is set to be arc-shaped.

[0027] By adopting the above technical solutions, the arc-shaped plate can better fit the inner surface of the pipe; the rubber sleeve on the outside of the plate can increase the supporting friction, making the support more stable.

[0028] Furthermore, a drive motor 8 is fixedly installed on the right side of the outer surface of the covering cylinder 2, and the rotating shaft of the drive motor 8 passes through the covering cylinder 2 and is connected to the bidirectional lead screw 4.

[0029] By adopting the above technical solution, the drive motor 8 can provide rotational power to the bidirectional lead screw 4.

[0030] Furthermore, light strips 9 are fixedly connected to both the left and right sides of the outer surface of the connecting cylinder 1, and four cameras 10 are fixedly connected to the center of the surface of the connecting cylinder 1 in a circumferentially even distribution.

[0031] By adopting the above technical solution, the four cameras 10 can cover all surfaces inside the pipe, thus completely detecting the entire inner surface of the pipe.

[0032] The camera 10 can move along with the covering cylinder 2 using the connecting cylinder 1, thereby performing detection and inspection of the entire pipeline;

[0033] The light strip 9 can provide supplementary lighting for the camera 10, ensuring clear detection even when inserted into a pipe.

[0034] Working Principle: When using this multi-probe telescopic device for rapid leakage detection in water conservancy projects, firstly, the entire device is inserted into the pipeline structure. Then, the right-side double-acting screw 4 is rotated. As the double-acting screw 4 rotates, the threaded sleeve 5 moves in opposite directions, causing the movable rod 6 to carry the support plate 7 outward and push it up. The support plate 7 is pressed tightly against the inner surface of the pipeline, thus centrally fixing and supporting the entire device. Then, the electric telescopic rod 3 extends, pushing the left-side covering cylinder 2 forward. When it reaches its maximum position, the left-side double-acting screw 4 rotates, using the same steps to press and fix the support plate 7 tightly against the pipeline. Then, the right-side double-acting screw 4 reverses, causing the support plate 7 to detach from the inner surface of the pipeline, i.e., the right-side covering cylinder 2 is released from fixation. At this time, the electric telescopic rod 3 retracts. The device is fixed to the left end of the covering cylinder 2. When the electric telescopic rod 3 retracts, it will drive the right side of the covering cylinder 2 to move to the left. By repeating the above steps, the device can automatically crawl and move inside the pipe. During the crawling movement, it will also drive the camera 10 to move, thereby illuminating and detecting the entire pipe. The light strip 9 can provide supplementary lighting for the camera 10, ensuring clear detection even when it is inserted into the pipe. A locator can be installed on the entire device. After the device crawls and clearly detects and determines the leakage location, the locator can be used to locate the device position. The leakage location of the pipe can be directly determined from the corresponding position on the ground surface, and excavation can be carried out directly at this location. This is the working principle of the multi-probe telescopic device for rapid leakage detection in water conservancy projects.
