Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and more specifically, to a pipeline pressure testing device for water conservancy engineering. Background Technology

[0002] Water conservancy engineering is a broad and complex field that involves a series of engineering measures for preventing water-related disasters and developing and utilizing water resources. When installing water conservancy pipelines, pressure testing can be used to detect whether there are any leaks or potential safety hazards in the pipelines.

[0003] A search revealed that Chinese Patent Publication No. CN217901357U discloses "a pipeline pressure testing device, including a base, a through groove on the upper surface of the base, support frames slidably mounted on both the left and right ends of the through groove, an adjusting rod rotatably mounted inside the through groove, the adjusting rod being threadedly connected to the two support frames respectively, the adjusting rod extending to the left and penetrating the base, a first motor connected to the left end of the adjusting rod, the first motor being connected to an external power source, an arc-shaped plate on the upper end of each of the two support frames, a bracket on the upper end of the base, a support seat slidably mounted on the top of the bracket, an electric push rod on the lower end of the support seat, the electric push rod being connected to an external power source, and a detection plate on the bottom end of the electric push rod; the design of the support frames facilitates the placement of pipelines of different lengths; the design of the support seat improves the testing efficiency; and the design of the arc-shaped plates facilitates disassembly and assembly." However, it still has the following drawbacks:

[0004] When placing the pipe, the device can only support it. Before the detection plate descends, the pipe is not secured. If the device moves as a whole, the pipe may fall, potentially damaging the pipe that should have passed inspection.

[0005] Therefore, we have made improvements to this and proposed a pipeline pressure testing device for water conservancy projects. Utility Model Content

[0006] The purpose of this invention is to address the problem that existing pipeline pressure testing devices for water conservancy projects can only support the pipeline when it is placed. Before the testing plate descends, the pipeline is not fixed. If the entire device moves, the pipeline may fall, potentially damaging the pipeline that should have passed the test.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0030] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] like Figure 1-6 As shown, this embodiment proposes a pipeline pressure testing device for water conservancy projects, including a base plate 1, a testing mechanism 2 is provided on the top of the base plate 1, and an adjustment component 3 is provided on one side of the testing mechanism 2.

[0034] like Figure 3 Figure 5 and Figure 6 As shown, the testing mechanism 2 includes a limiting plate 201, a hydraulic rod 202, an arc-shaped plate 203, a pressure sensor 204, an electric telescopic rod 205, a push plate 206, and a display screen 207. The limiting plate 201 is located at the top end of the base plate 1, the hydraulic rod 202 is located above the base plate 1, the arc-shaped plate 203 is fixedly connected to the telescopic end of the hydraulic rod 202, the pressure sensor 204 is located at the bottom of the arc-shaped plate 203, the electric telescopic rod 205 is fixedly connected to the top end of the base plate 1 away from the limiting plate 201, the push plate 206 is fixedly connected to the telescopic end of the electric telescopic rod 205, and the display screen 207 is fixedly connected to the base plate 1. The top of the plate is connected to the pressure sensor 204 via electrical signal. The curvature of the arc plate 203 is the same as the curvature of the outer wall of the pipe to be tested. During use, one end of the pipe to be tested is placed against the side wall of the limiting plate 201. Then, the electric telescopic rod 205 drives the push plate 206 to move until the push plate 206 is close to the side wall of the pipe and against one end of the pipe. Then, the electric telescopic rod 205 is closed, thereby clamping the pipe. Then, the hydraulic rod 202 drives the arc plate 203 and the pressure sensor 204 to descend, thereby performing a pressure test on the pipe. At this time, the pressure sensor 204 will transmit the pressure data to the display screen 207 for the workers to understand.

[0035] like Figure 3 and Figure 4 As shown, the adjustment assembly 3 includes a fixed plate 301, a moving groove 302, a lead screw 303, a motor 304, a moving block 305, and an extension plate 306. The fixed plate 301 is disposed on the top of the base plate 1 and located on one side of the limiting plate 201. The moving groove 302 is formed on the side wall of the fixed plate 301. The lead screw 303 is rotatably connected to the inside of the moving groove 302. The motor 304 is fixedly connected to one end of the fixed plate 301. The moving block 305 is threadedly connected to the outside of the lead screw 303. The extension plate 306 is fixedly connected to the moving block. On the side wall of 305 near the limiting plate 201, the top of the hydraulic rod 202 is fixedly connected to the bottom of the extension plate 306. The output end of the motor 304 is coaxial with the lead screw 303, and the motor 304 can drive the lead screw 303 to rotate. When in use, after testing a certain part of the pipeline, the motor 304 can be started. The motor 304 drives the lead screw 303 to rotate, thereby changing the horizontal position of the moving block 305, the hydraulic rod 202, the arc plate 203 and the pressure sensor 204, so as to test other parts of the pipeline.

[0036] like Figure 4 As shown, a limiting hole 4 is provided on the side wall of the fixed plate 301, and a limiting block 5 is fixedly connected to the side wall of the moving block 305 away from the extension plate 306. The limiting block 5 is located inside the limiting hole 4 and is slidably connected to the limiting hole 4. The top and bottom of the limiting block 5 are respectively attached to the inner top wall and inner bottom wall of the limiting hole 4. When the moving block 305 moves along the screw 303, the limiting block 5 will also slide inside the limiting hole 4. At the same time, when testing the pipeline, the limiting block 5 can prevent the moving block 305 from rotating inside the moving groove 302, thereby improving the accuracy of the test.

[0037] like Figure 1 As shown, four casters 6 are bolted to the bottom of the base plate 1. The four casters 6 are located at the four corners of the base plate 1. All four casters 6 have a self-locking function. When in use, the device can be moved to a designated position through the casters 6, which improves convenience.

[0038] like Figure 1 As shown, a guide plate 7 is hinged to the side wall of the base plate 1 to facilitate pipe unloading. The end of the guide plate 7 away from the base plate 1 is in contact with the ground. After a pipe is tested, the pipe is rolled over the guide plate 7. The guide plate 7 can prevent the pipe from falling directly to the ground and causing damage. When the guide plate 7 is not in use, the guide plate 7 is rotated toward the fixed plate 301 until the corner of the fixed plate 301 is in contact with the top wall of the guide plate 7, so as to avoid the guide plate 7 from colliding with the protrusions on the ground when the base plate 1 is moved.

[0039] like Figure 1As shown, an arc-shaped groove 8 is provided on the top of the base plate 1. The arc-shaped groove 8 is located directly below the push plate 206. When in use, the arc-shaped groove 8 can provide support for the outer wall of the pipe to be tested, making it convenient for the push plate 206 to fix one end of the pipe.

[0040] like Figure 1 As shown, a buffer pad 9 is fixedly connected to the side wall of the limiting plate 201 near the electric telescopic rod 205. When in use, the buffer pad 9 can provide protection for one end of the pipe to be tested, preventing damage to that end.

[0041] Specifically, when using the pipeline pressure testing device for this water conservancy project: the device is moved to the designated position using the casters 6 and the casters 6 are locked. Then, the pressure sensor, display screen 207, electric telescopic rod 205, and motor 304 are connected to an external power source. The pipeline to be tested is then placed inside the arc-shaped groove 8, and one end of the pipeline is brought into contact with the side wall of the limiting plate 201. The electric telescopic rod 205 then moves the push plate 206 until the push plate 206 is close to the side wall of the pipeline and in contact with one end of the pipeline. The electric telescopic rod 205 is then closed, thus clamping the pipeline. Next, the hydraulic rod 202 lowers the arc-shaped plate 203 and the pressure sensor 204, thereby performing a pressure test on the pipeline. At this time, the limiting block 5 can prevent the moving block 305 from rotating inside the moving groove 302, thus improving the accuracy of the test. After a certain part of the pipeline is tested, the telescopic end of the hydraulic rod 202 can be raised, and then the motor 304 can be started. The motor 304 drives the lead screw 303 to rotate, thereby changing the horizontal position of the moving block 305, the hydraulic rod 202, the arc plate 203 and the pressure sensor 204, so that other parts of the pipeline can be tested. The pressure sensor 204 will transmit the pressure data to the display screen 207 for the workers to understand. After a pipeline is tested, the pipeline is rolled above the guide plate 7. The guide plate 7 can prevent the pipeline from falling directly to the ground and causing damage.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
