[0002] The water conservancy project pipeline joint sealing test device is a specialized device used to inspect the sealing performance of pipeline connections. It accurately determines whether there is leakage by applying a specified pressure (such as air or water pressure) to the pipe section or joint and monitoring pressure changes in real time. The core function of this device is to ensure the safe operation of the pipeline system, effectively preventing major hidden dangers such as water resource loss, foundation settlement, and even operational paralysis caused by joint leaks. It is a key testing tool for ensuring the quality and long-term stability of municipal and water conservancy projects such as water supply and drainage.

[0003] Existing pipeline interface sealing testing devices require the use of numerous screws and nuts to secure a gas booster pump to the pipeline before testing. This process is time-consuming, labor-intensive, and complex. A new pipeline interface sealing testing device for water conservancy projects is proposed to address these issues.

[0004] To address the problems mentioned in the background section, this utility model provides a water conservancy project pipeline interface sealing detection device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing detection device for pipeline interfaces in water conservancy projects, comprising a sealing detection mechanism, wherein the sealing detection mechanism includes a gas booster pump, a fixed base is fixedly installed at the bottom of the gas booster pump, a connecting pipe is fixedly installed at the opening of the gas booster pump, and a connecting ring passes through the end of the connecting pipe away from the gas booster pump and is fixedly connected to the connecting ring; it also includes a limiting mechanism, disposed at one end of the sealing detection mechanism, for positioning and clamping the pipeline; a clamping mechanism, fixedly installed on the outer surface of the connecting ring, for improving the sealing performance of the pipeline connection; the limiting mechanism includes a clamping plate, a groove is provided on one side of the clamping plate, a slider is slidably connected to the inner wall of the groove, and an inclined block A is fixedly connected to one side of the slider.

[0006] Preferably, the limiting mechanism further includes a spring telescopic rod, a groove is formed on the circumferential surface of the connecting ring, one end of the spring telescopic rod is fixedly connected to the inner wall of the groove, the other end of the spring telescopic rod is fixedly connected to the side of the clamping plate near the slide groove, a spring is fixedly connected to the side of the connecting ring near the gas booster pump, a pressure ring is fixedly connected to the end of the spring away from the connecting ring, a pressure block is fixedly connected to the side of the pressure ring near the spring, and an inclined block B is fixedly connected to the side of the clamping plate near the inclined block A.

[0007] Preferably, the number of clamping plates is four, and they are arranged in a circumferential array on the circumferential surface of the connecting ring. The inclined surface of the inclined block B is located on the displacement trajectory of the pressure block. The number of springs is four, and they are arranged in a circumferential array on the side of the connecting ring near the pressure block.

This achieves the goal of fixing the pipe to the gas booster pump without the need for screws and nuts, saving time and effort, and simplifying operation.

[0014] This utility model utilizes components such as a fixed plate, a sliding plate, and a slider to achieve secondary clamping and fixing of the pipeline, ensuring the sealing of the connection between the pipeline and the gas booster pump. This is achieved by the cooperation of components such as a fixed plate, a sliding plate, and a slider. Attached Figure Description

[0021] 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.

[0022] like Figures 1 to 3 As shown, this utility model provides a sealing detection device for pipeline joints in water conservancy projects, including a sealing detection mechanism 1. The sealing detection mechanism 1 includes a gas booster pump 101, a fixed base 102 fixedly installed at the bottom of the gas booster pump 101, a connecting pipe 103 fixedly installed at the opening of the gas booster pump 101, and a connecting ring 104 passing through the end of the connecting pipe 103 away from the gas booster pump 101 and fixedly connected to the connecting ring 104. It also includes a limiting mechanism 2, which is set at one end of the sealing detection mechanism 1 for positioning and clamping the pipeline; a pressing mechanism 3, which is fixedly installed on the outer surface of the connecting ring 104 for improving the sealing performance of the pipeline joint; the limiting mechanism 2 includes a clamping plate 203, a sliding groove 303 is opened on one side of the clamping plate 203, a slider 304 is slidably connected to the inner wall of the sliding groove 303, and an inclined block A204 is fixedly connected to one side of the slider 304.

[0023] The limiting mechanism 2 also includes a spring telescopic rod 201. A groove 202 is provided on the circumferential surface of the connecting ring 104. One end of the spring telescopic rod 201 is fixedly connected to the inner wall of the groove 202, and the other end of the spring telescopic rod 201 is fixedly connected to the side of the clamping plate 203 near the slide groove 303. A spring 205 is fixedly connected to the side of the connecting ring 104 near the gas booster pump 101. A pressure ring 206 is fixedly connected to the end of the spring 205 away from the connecting ring 104. A pressure block 207 is fixedly connected to the side of the pressure ring 206 near the spring 205. An inclined block B208 is fixedly connected to the side of the clamping plate 203 near the inclined block A204. The above design is beneficial for the initial clamping and positioning of the pipeline.

[0024] There are four clamping plates 203 arranged in a circumferential array on the circumferential surface of the connecting ring 104. The inclined surface of the inclined block B208 is located on the displacement trajectory of the pressure block 207. There are four springs 205 arranged in a circumferential array on the side of the connecting ring 104 near the pressure block 207. The above design is beneficial for the pressure block 207 to squeeze the inclined block B208, thereby causing the inclined block B208 to drive the clamping plates 203 to move.

[0025] The side of the inclined block A204 near the slider 304 is in contact with the side of the clamping plate 203 near the slide groove 303. The clamping plate 203 is located between the inclined block A204 and the inclined block B208. The above design is beneficial for clamping and positioning the pipe through the inclined block A204.

[0026] Through the mutual contact between the pipe and the inclined block A204, the inclined block A204 is squeezed, causing the inclined block A204 to push the clamping plate 203, which in turn causes the clamping plate 203 to move the inclined block A204 away from the pipe. When the pipe moves away from the inclined surface of the inclined block A204, the clamping plate 203 will use the reset property of the spring telescopic rod 201 to cause the clamping plate 203 to move the inclined block A204 to perform initial clamping and positioning of the pipe.

[0027] like Figures 3 to 5 As shown, the clamping mechanism 3 includes a fixed plate 301. One side of the fixed plate 301 is fixedly connected to the circumferential surface of the connecting ring 104. A groove 305 is provided on one side of the fixed plate 301. A sliding plate 302 is slidably connected to the inner wall of the clamping plate 203. A sliding rod 306 is fixedly connected to one side of the sliding plate 302. The end of the sliding rod 306 away from the sliding plate 302 passes through the sliding plate 302 and is slidably connected to the clamping plate 203. The above design is conducive to secondary positioning and clamping of the pipeline, ensuring the sealing of the pipeline and the gas booster pump 101.

[0028] The slide rods 306 are arranged in pairs and are symmetrical about each other along the vertical central axis of the slide plate 302. The fixed plates 301 are arranged in pairs and are arranged in a circular array on the circumferential surface of the connecting ring 104. The clamping plate 203 is located between the two fixed plates 301. The above design is conducive to the slide plate 302 sliding within the clamping plate 203 by driving the slide rods 306.

[0029] The end of the slide bar 306 away from the slide plate 302 is slidably connected to the inner wall of the inclined groove 305, and the end of the slider 304 away from the inclined block A204 is fixedly connected to the slide plate 302. The above design is conducive to driving the slide bar 306 to move by the inclination angle of the inclined groove 305.

[0030] Working principle and usage process of this utility model:

[0031] During testing, the pipe interface to be tested is inserted into the connecting ring 104 of the sealing testing mechanism 1. The pipe first contacts the inclined block A204 in the limiting mechanism 2 and pressure is applied. This pressure forces the inclined block A204 to push the clamping plate 203 connected to it to move outward against the elastic force of the spring telescopic rod 201, thus allowing the pipe to smoothly penetrate. When the end of the pipe passes the inclined surface of the inclined block A204, the reset elastic force of the spring telescopic rod 201 drives the clamping plate 203 to return to its original position, causing the inclined block A204 to tightly clamp the outer wall of the pipe, completing the initial automatic positioning and clamping of the pipe. This process does not require traditional screw and nut fixing, making the operation simple and efficient. Based on the initial clamping, the pressing mechanism 3 is then activated to achieve secondary sealing reinforcement. When the clamping plate 203 is in... When displacement occurs during the initial action or under force, the slide plate 302 fixed thereon moves accordingly. The slide plate 302 drives the slide rod 306 to slide in the inclined groove 305 of the fixed plate 301. Due to the guiding effect of the inclined surface of the inclined groove 305, the movement of the slide rod 306 is converted into a radial force perpendicular to the pipe axis, pushing the slide plate 302 to slide inside the clamping plate 203. The slide plate 302 then drives the inclined block A204 to make fine adjustments or further tighten the pipe through the slider 304, which significantly enhances the sealing pressure at the connection between the pipe interface and the connecting ring 104 and the gas booster pump 101, ensuring zero gas leakage during the test and providing a reliable guarantee for subsequent precise sealing test by injecting high-pressure gas through the gas booster pump 101.
