Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of fluid pressure test, specifically relates to a portable glass reinforced plastic pipeline water pressure detection device. BACKGROUND

[0002] Glass reinforced plastic is a kind of composite material, which is composed of glass fiber and resin matrix, has excellent corrosion resistance, good mechanical properties and relatively light characteristics, and is widely used in chemical industry, petroleum, natural gas, water supply and drainage and other fields. Since glass reinforced plastic pipeline is often used to transport corrosive medium or work in high pressure environment, it is very important to verify its strength and sealing property. Water pressure test is one of the effective methods to confirm these properties. By injecting liquid (usually water) into the pipeline and applying pressure higher than normal operating pressure, it can be tested whether the pipeline has leakage, rupture or other defects, which helps to find potential problems in advance and avoid failure in future operation.

[0003] In the prior art, the water pressure detection device of glass reinforced plastic pipeline is usually large in size. Due to its large size, these devices are not only difficult to carry, but also not suitable for on-site mobile operation. In actual operation, it may be necessary to carry glass reinforced plastic pipelines of various sizes to the detection equipment for measurement, which affects the detection efficiency. In addition, considering that the inner diameters of different glass reinforced plastic pipelines are different, in order to ensure that each pipeline can be stably fixed during the test process, the fixing device must be frequently adjusted. This process not only consumes time, but also increases the operation complexity, which brings great inconvenience to the detection work. UTILITY MODEL CONTENTS

[0024] Secondly, the "one embodiment" or "embodiment" referred to here means that specific features, structures or characteristics can be included in at least one implementation of the utility model. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0025] EMBODIMENT

[0026] REFERENCE Figs. 1-4 For the embodiment of the utility model, the embodiment provides a portable glass steel pipeline water pressure detection device, which comprises,

[0027] The bearing mechanism 100 comprises a support plate 101, a universal lock wheel 102 fixedly installed at the bottom of the support plate 101, and a push handle 103 fixedly installed on the outer surface of the support plate 101.

[0028] The driving mechanism 200 comprises an operation table 201 fixedly installed on the outer surface of the support plate 101, a cylinder 202 adaptively installed on the outer surface of the operation table 201, a fixed disc 203 fixedly installed on the outer surface of the operation table 201, a sealing gasket 204 fixedly connected on the outer surface of the fixed disc 203, a clamping assembly 205 used in cooperation with the cylinder 202, a glass fiber reinforced plastic pipe body 206 used for testing, and a detection assembly 207 arranged on the outer surface of the support plate 101 and in communication with the glass fiber reinforced plastic pipe body 206.

[0029] The detection assembly 207 comprises a pressure pump, a connecting pipe, a water inlet pipe and a pressure gauge. The pressure pump is used to slowly inject water into the glass fiber reinforced plastic pipe body 206. As the water volume increases, the internal pressure is gradually increased to a predetermined test value by using the pressure pump. After the set pressure is reached, the work of the pressure pump is stopped, and the pressure is maintained for a period of time. Then, the pressure drop is checked by the change of the pressure gauge reading.

[0030] Specifically, the output end of the cylinder 202 penetrates the outer surface of the fixed disc 203, and the outer surface of the output end of the cylinder 202 is in sliding contact with the inner surface of the fixed disc 203.

[0031] Further, the clamping assembly 205 comprises a fixed column 205a fixedly installed on the outer surface of the fixed disc 203, a fixed sleeve 205b fixedly installed on the output end of the fixed column 205a, a plurality of first guide rods 205c rotatably connected to the inner surface of the fixed sleeve 205b, and a plurality of limiting blocks 205d fixedly installed on the outer surface of the fixed column 205a.

[0032] Still further, the clamping assembly 205 further comprises a second guide rod 205e rotatably connected to the inner surface of the limiting block 205d, and an arc-shaped clamping plate 205f rotatably connected to the inner surfaces of the first guide rod 205c and the second guide rod 205e.

[0033] The clamping assembly 205 driven by the cylinder 202 can automatically adjust according to the different inner diameters of the glass fiber reinforced plastic pipe body 206, ensuring that the pipe is firmly fixed without manual adjustment, greatly improving the work efficiency and reducing the operation difficulty.

[0034] Still further, a bearing sleeve is installed at the connection between the fixed sleeve 205b and the first guide rod 205c, and a bearing sleeve is installed at the connection between the limiting block 205d and the second guide rod 205e for cooperation in rotation.

[0035] Preferably, a bearing sleeve is installed at the connection between the first guide rod 205c and the arc-shaped clamping plate 205f, and a bearing sleeve is installed at the connection between the second guide rod 205e and the arc-shaped clamping plate 205f for cooperation in rotation.

[0036] It should be noted that the arc-shaped clamping plate 205f is attached to the inner surface of the glass steel pipe body 206, and the outer end surface of the glass steel pipe body 206 is attached to the outer surface of the sealing gasket 204.

[0037] By tightly attaching the sealing gasket 204 to the outer end surface of the glass steel pipe body 206, the leakage problem that may occur during testing is effectively prevented, ensuring the accuracy of the test results.

[0038] In use, first, push the handle 103 to move the entire device to the test area, and check whether the universal locking wheel 102 is locked to prevent movement, then set one end of the glass steel pipe body 206 to be tested on the outer surface of the arc-shaped clamping plate 205f, and then connect the other end of the glass steel pipe body 206 to the pipe port of the detection assembly 207, ensuring good sealing, start the air cylinder 202, and automatically adjust and firmly clamp the glass steel pipe body 206 through the system composed of the fixed column 205a, the fixed sleeve 205b, the first guide rod 205c, the limiting block 205d, the second guide rod 205e, and the arc-shaped clamping plate 205f, all connecting parts are equipped with bearing sleeves to ensure smooth movement without resistance, at the same time, the outer end surface of the glass steel pipe body 206 is attached to the sealing gasket 204 to avoid water leakage, start the pressure pump, and slowly inject water into the glass steel pipe body 206. As the water volume increases, gradually increase the internal pressure to the predetermined test value, observe the change of the pressure gauge reading, and check whether there is a pressure drop.

[0039] In summary, through the cooperation of the bearing mechanism 100 and the driving mechanism 200, not only the problem of large size and inconvenience of traditional large equipment is solved, but also different sizes of glass steel pipe bodies 206 can be adapted, reducing the adjustment time and complexity of the fixing device.
