Description

Technical Field

[0001] The utility model relates to the field of water conservancy project detection, in particular to a pipeline quality detection device for water conservancy projects. Background Art

[0002] Water conservancy projects are constructed to control and regulate natural surface water and groundwater, achieving the goal of eliminating harm and promoting benefits. Pipelines are an indispensable part of water conservancy projects, and strict quality requirements are imposed on the pipelines used in water conservancy projects. Poor airtightness can cause pipeline ruptures during use, leading to high subsequent repair costs. Therefore, before the pipelines are put into use, they must be tested for airtightness using testing equipment. Only pipelines that meet the standards can be put into use in water conservancy projects.

[0003] For example, patent document CN220829320U discloses a pipeline quality inspection device for water conservancy projects. This device clamps the two ends of the pipeline with limit blocks, then submerges the pipeline in water and inflates and pressurizes it to test the pipeline's airtightness. However, when using this device, the pipeline must be inspected and removed before a new one can be inserted. The efficiency of installing and removing the pipeline also affects the overall inspection efficiency. In addition, the pipeline needs to be clamped, flipped, and submerged, which requires many steps, resulting in low overall inspection efficiency. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

Therefore, they cannot be understood as limitations on the present invention.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-6As shown, a pipeline quality inspection device for water conservancy projects includes a water tank 1. Two placement platforms 2 are installed inside the water tank 1 and are slidably mounted in the up-down direction. The top surface of the placement platform 2 is V-shaped, which can easily place the pipe. The two placement platforms 2 move up and down alternately, that is, when one placement platform 2 moves down, the other placement platform 2 rises. The two placement platforms 2 are distributed in the front-to-back direction. A sealing mechanism is provided on both sides of the placement platform 2. The sealing mechanism includes two clamping plates 301. The clamping plates 301 are provided on both sides of the placement platform 2. A sealing ring 30 is fixedly connected to the side of the clamping plate 301 close to the placement platform 2. 2. An air inlet pipe 4 is fixedly connected to the top of one sealing ring 302, and the air inlet pipe 4 is communicated with an external air pump. A pressure gauge 5 is fixedly connected to the top of the other sealing ring 302. The two clamps 301 are close to each other so that the sealing rings 302 are sleeved on the outside of the two ends of the pipe. The air inlet pipe 4 is ventilated by an external air pump, thereby pressurizing the inside of the pipe. The pipe is sunk into the water tank 1 to detect the air tightness of the pipe. The pressure resistance of the pipe can be detected by the reading of the pressure gauge 5. A lifting mechanism is provided between the front and rear placement platforms 2. The lifting mechanism is used to move the two placement platforms 2 up and down alternately.

[0028] The sealing mechanism also includes a slide bar 303, which is screwed to the side of the splint 301 close to the placement platform 2, and the other end of the slide bar 303 extends into the placement platform 2 and is slidably connected to the placement platform 2. One end of the slide bar 303 located inside the placement platform 2 is fixedly connected to a spring 304, and the spring 304 is used to make the two splints 301 loosen the pipe. The sealing mechanism also includes a lifting wedge 305 and an extrusion plate 306. The lifting wedge 305 is welded to the side of the splint 301 away from the placement platform 2, and the extrusion plate 306 is welded to the inner wall of the water tank 1. The lifting wedge 305 and the extrusion plate 306 correspond to each other up and down, and the lifting The bottom surface of the wedge block 305 and the top surface of the extrusion plate 306 are both set as inclined surfaces. When the placement table 2 moves downward, the sliding rod 303 will drive the clamping plate 301 to move downward, and the clamping plate 301 will drive the lifting wedge block 305 to move downward. The lifting wedge block 305 and the extrusion plate 306 squeeze each other, causing the clamping plate 301 to move toward the placement table 2, so that the two sealing rings 302 are automatically sleeved on the two ends of the pipeline to achieve automatic sealing of the pipeline. A convex ring 307 is fixedly connected to the inner wall of the sealing ring 302, and the convex ring 307 can be pressed against the two ends of the pipeline to improve the clamping stability of the pipeline and the sealing between the sealing ring 302 and the pipeline.

[0029] Sliders 201 are welded to the front and rear sides of the placement table 2. A guide rod 202 is slidably connected inside the slider 201. The guide rod 202 is fixedly connected to the bottom end of the water tank 1. The placement table 2 can be stably raised and lowered through the cooperation between the slider 201 and the guide rod 202.

[0030] The lifting mechanism includes two support plates 601, which are connected to both sides of the water tank 1 by screws. A rotating shaft 602 is connected between the support plates 601 through bearings. A motor 603 is connected to one side of the support plate 601 by bolts. The output shaft of the motor 603 is fixedly connected to the rotating shaft 602. A gear 604 is fixedly connected to the rotating shaft 602. Racks 605 are meshed with the front and rear sides of the gear 604. The two racks 605 are respectively connected to the two placement platforms 2 by screws.

[0031] Working principle: When in use, place the pipe on the front placement table 2, and use the motor 603 to drive the rotating shaft 602 to rotate, and the rotating shaft 602 drives the gear 604 to rotate. The gear 604 drives the front rack 605 to move downward, and at the same time, the gear 604 drives the rear rack 605 to move upward, so that the front placement table 2 moves downward and the rear placement table 2 moves upward, so that the pipe on the front placement table 2 sinks into the water for inspection, and the pipe on the rear placement table 2 rises from the water. Therefore, when one pipe is being inspected, the other pipe can be disassembled and assembled, thereby improving efficiency.

[0032] During the downward movement of the placement platform 2, the placement platform 2 drives the splint 301 to move downward through the sliding rod 303, and the splint 301 drives the lifting wedge 305 to move downward. The lifting wedge 305 and the extrusion plate 306 squeeze each other, so that the splint 301 is close to the placement platform 2, the spring 304 is compressed, and the sealing ring 302 is sleeved on both ends of the pipeline to seal the pipeline. When the pipeline sinks into the water, an external air pump is used to ventilate the air inlet pipe 4 to pressurize the pipeline. In this way, the air tightness of the pipeline is tested, and the pressure resistance of the pipeline can be tested by using the indication of the pressure gauge 5.

[0033] When the placement platform 2 rises above the water surface, as the placement platform 2 continues to move upward, the lifting wedge 305 and the extrusion plate 306 will lose contact, and the spring 304 will rebound, so that the clamping plate 301 will move away from the placement platform 2, thereby loosening the pipeline. The staff can easily remove the pipeline and replace it with a new pipeline, which is convenient and quick to use.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
