Description

Technical Field

[0001] The utility model relates to the technical field of leakage prevention in drainage engineering, in particular to a leakage prevention safety inspection device for drainage engineering. Background Art

[0002] Drainage equipment refers to the drainage and transportation facilities that are combined in a certain way. It is a general term for drainage ditches and buildings at all levels for waterlogging, waterlogging and salt prevention. The leakage prevention and safety of pipes in this kind of drainage project is particularly important. Some drainage pipes are exposed and easily damaged, which may cause the outer wall of the pipe to rupture and slowly seep water, thus posing certain safety hazards.

[0003] Existing leak prevention and safety inspections often require manual inspection of each pipe end. If the pipe is too long, the entire inspection process will be too time-consuming and inefficient. When the supporting device is conducting inspections, a pressure valve is generally installed between pipes at a certain distance. The pressure valve is used to determine whether a leak has occurred in the pipe section based on the change in pressure. However, when the leak is too small and the amount of water is not large, it is difficult for the pressure valve to quickly sense the change in pressure, which poses a certain risk. Therefore, a device is needed to solve the problem. Utility Model Content

[0022] Embodiment 1

[0023] Reference Figure 1-4 A leak-proof safety inspection device for drainage engineering includes two protective shells 1. In order to facilitate the movement of the safety inspection device along the pipeline for inspection, a driving mechanism 2 is arranged on the two protective shells 1. The driving mechanism 2 includes a linkage unit 21 and a clamping unit 22. The movement of the two protective shells 1 is maintained by the linkage unit 21. The clamping unit 22 provides a fulcrum. The linkage unit 21 is installed between the two protective shells 1. The clamping unit 22 is arranged on the inner side of each protective shell 1, and the two ends extend to the outside of the protective shell 1 and are movably connected to the pipeline. A connecting rod 3 is movably connected between the two protective shells 1. A inspection mechanism 4 is fixedly connected to the connecting rod 3. The inspection mechanism 4 is coaxially arranged on the outside of the pipeline. The inspection mechanism 4 observes the humidity of the outer wall of the pipeline. The humidity in the inspection sleeve 42 is stable under normal circumstances. If there is a water leak, the humidity increases and the humidity sensor 45 changes. Among them, the model of the humidity sensor 45 is HS1101LF.

[0024] In the present embodiment, specifically, when in use, the movement of the driving mechanism 2 drives the inspection mechanism 4 to move along the pipeline for inspection, thereby replacing the traditional manual inspection, saving time and labor, reducing the workload of workers, and improving work efficiency. Specifically, the clamping unit 22 is loosened and moved, and the linkage unit 21 cooperates to drive the inspection mechanism 4 to move synchronously, observe and collect data at various locations on the outer wall of the pipeline, and reduce safety hazards. The entire operation process does not require manual inspection along the pipeline, and can be remotely controlled, which is safe and efficient.

[0025] Embodiment 2

[0026] like Figure 1-2 As shown, this embodiment is basically the same as embodiment 1. Preferably, the linkage unit 21 includes a motor 211, a driving gear 212 and a rotating rod 213. The motor 211 is fixedly connected to the inner wall of the protective shell 1, the driving gear 212 is coaxially fixedly connected to the output shaft of the motor 211, the rotating rod 213 is rotatably connected to the inner wall of the protective shell 1, and a driven gear 214 meshing with the driving gear 212 is coaxially fixedly connected to the rotating rod 213. A connecting rod 215 is movably connected between the two ends of the rotating rods 213 on the two protective shells 1.

[0027] In this embodiment, specifically, when in use, the starting motor 211 drives the driving gear 212 to rotate, the driving gear 212 engages with the driven gear 214 to drive the rotating rod 213 to rotate, and the rotating rod 213 drives the connecting rods 215 at both ends to rotate, thereby pulling the other protective shell 1 forward or backward. During the movement, the clamping unit 22 remains in a relaxed state and is clamped after the movement is completed.

[0028] Embodiment 3

[0029] like Figure 1-2 As shown, this embodiment is basically the same as embodiment 1. Preferably, the clamping unit 22 includes a guide rail 221 and a cylinder 222. The guide rail 221 is fixedly connected to the inner wall of the protective shell 1. The cylinder 222 is provided with two cylinders both mounted on the guide rail 221. The output shaft of the cylinder 222 is connected to a slider 223 which is slidably connected to the guide rail 221. One end of the slider 223 is rotatably hinged with a folding rod 225. One end of the folding rod 225 is integrally fixedly connected with a clamping arm 226. The clamping arm 226 is movably clamped to the pipeline. A limiting rod 224 is provided on the outer wall of the protective shell 1. The folding rod 225 is rotatably connected to the limiting rod 224. The clamping arm 226 is an arc-shaped structure, and its inner wall is detachably connected with anti-slip rubber.

[0030] In this embodiment, specifically, when moving, the cylinder 222 controls the slider 223 to slide along the guide rail 221, thereby pushing the folding rod 225 to rotate around the limiting rod 224, and then controlling the operation of the clamping arm 226, so that the device can clamp the pipeline and maintain its own stability. The shape of the clamping arm 226 fits the pipeline more closely, thereby improving stability.

[0031] Embodiment 4

[0032] like Figure 3 and Figure 4 As shown, this embodiment is basically the same as embodiment 1. Preferably, the troubleshooting mechanism 4 includes a fixed block 41, a troubleshooting sleeve 42, an elastic connecting column 43, an elastic absorbent cotton 44 and a humidity sensor 45. The fixed block 41 is fixedly connected to the connecting rod 3, the troubleshooting sleeve 42 is sleeved on the outside of the pipeline, the elastic connecting column 43 is fixedly connected between the outer wall of the troubleshooting sleeve 42 and the fixed block 41, the elastic absorbent cotton 44 is detachably connected to the two ends of the inner wall of the troubleshooting sleeve 42, a plurality of humidity sensors 45 are provided and evenly distributed on the inner wall of the troubleshooting sleeve 42, the troubleshooting sleeve 42 is made of hard rubber, and the inner diameter of the troubleshooting sleeve 42 is larger than the outer diameter of the troubleshooting pipeline.

[0033] In the present embodiment, specifically, during use, the elastic connecting column 43 can ensure that when the inspection sleeve 42 encounters an undulating area, it is more convenient to adapt to the deformation of the inspection sleeve 42, and the elastic absorbent cotton 44 can be used to clean the surface of the pipeline, thereby reducing the error of data collection, and can also absorb water droplets on the surface of the pipeline to reduce the error. Among them, the elastic absorbent cotton 44 absorbs the water droplets, and the humidity in the inspection sleeve 42 is stable. If a water leakage occurs, the humidity increases, and the humidity sensor 45 changes, prompting the staff that there is a water leakage. Otherwise, the drainage pipeline is normal.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
