Description

Technical Field

[0001] This utility model belongs to the field of plastic pipe testing technology, and specifically relates to a polyolefin pipe testing device. Background Technology

[0002] Testing of plastic pipes aims to ensure their quality, safety, and suitability, covering multiple aspects such as physical properties, chemical stability, and durability. The specific tests conducted will vary depending on the application and requirements.

[0003] During the research and development of polyolefin pipes, light exposure and corrosion resistance tests are required. Current testing equipment performs these tests separately, which is not suitable for the operating environments where some polyolefin pipes are simultaneously exposed to light and corrosion. Therefore, the test results are insufficient to accurately determine the actual performance of the polyolefin pipes. Thus, a new type of polyolefin pipe testing device is needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a polyolefin tube testing device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A polyolefin pipe testing device includes a frame, with a horizontal mounting plate installed on each of the two sides of the frame. Each mounting plate has a plurality of rotation limiting components installed on it, and the rotation limiting components on the two mounting plates are arranged in a one-to-one correspondence. Two corresponding rotation limiting components share a corrosion resistance testing component, and each corrosion resistance testing component is coaxially mounted with a test tube. An isolation plate is inserted between adjacent test tubes. A test lamp is provided at the top of each test tube, and a drive component for driving the corrosion resistance testing component is installed at one end of each corrosion resistance testing component.

[0007] As a preferred technical solution of this utility model, each of the corrosion resistance testing components includes: two sealing plugs respectively tightened at both ends of the test tube, one of the sealing plugs coaxially extending into a circulation tube that extends into the inner cavity of the test tube, and the end of the circulation tube connected to the sealing plug is provided with several through holes, and a drive impeller is installed inside the circulation tube.

[0008] In a preferred embodiment of this invention, one of the sealing plugs extends coaxially out of the battery, and a solution flow channel exists between the battery and the circulation tube.

[0009] As a preferred technical solution of this utility model, each of the rotation limiting components includes: a mounting base connected to the mounting plate, two horizontally arranged fixed wheels rotatably mounted at the bottom of the vertical notch of the mounting base, and two movable seats elastically and horizontally slidably mounted on both sides of the top of the notch of the mounting base, with the two movable seats being mirror images of each other, and each movable seat having a movable wheel rotatably mounted at one end extending out of the mounting base.

[0010] As a preferred embodiment of this utility model, each of the movable seats is connected to a spring at its square end, and the spring is also connected to the mounting base. Several first mounting bolts pass through the bottom of the mounting base, and the first mounting bolts are threadedly connected to the mounting plate.

[0011] As a preferred technical solution of this utility model, each of the drive components includes: a first gear coaxially and fixedly connected to the adjacent sealing shaft, the first gear meshing with a second gear, and the second gear coaxially and fixedly connected to a drive motor.

[0012] As a preferred embodiment of this utility model, the four corners of the drive motor are each provided with a second mounting bolt, and the second mounting bolts are threadedly connected to the mounting plate. The diameter of the first gear is larger than the diameter of the second gear.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. During the light exposure test, an isolation plate is inserted between the test tubes, and test lamps with different light intensities are turned on. Under the deceleration drive of the drive motor through the first and second gears, multiple test tubes slowly rotate to carry out light aging tests of different intensities. Thanks to the simultaneous conduct of multiple sets of aging tests with different light intensities, the test time of polyolefin tubes is greatly reduced.

[0015] Second, the corrosion resistance test is carried out simultaneously with the light exposure test. Driven by the impeller, the corrosive solution in the test tube flows from the axis of the test tube to the tube wall and then back to the axis, and so on, to test the corrosion resistance performance of the test tube. Thanks to the simultaneous light exposure and corrosion resistance test, the test environment is more closely related to the use environment, and the test results are more realistic and reliable.

[0029] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0030] Please see Figure 1-7A polyolefin tube testing device includes a frame 1, with a horizontal mounting plate 2 installed on each side of the frame 1. Each mounting plate 2 has several rotation limiting components 3, and these components are arranged in a one-to-one correspondence. Two corresponding rotation limiting components 3 share a common corrosion resistance testing component 5, and each corrosion resistance testing component 5 has a test tube 6 coaxially mounted on it. The test tube 6 is a polyolefin tube. Isolation plates 7 are inserted between adjacent test tubes 6. A test lamp 8 is installed at the top of each test tube 6. The isolation plates 7 isolate light of different intensities emitted by different test lamps 8, allowing the test tube 6 to undergo light aging tests of different intensities. A drive component 4 is installed at one end of each corrosion resistance testing component 5. The drive component 4 drives the test tube 6 to rotate for light aging tests.

[0031] The tops of both the isolation plate 7 and the test lamp 8 extend laterally for hanging on the top of the frame 1. The top of the frame 1 is provided with slots for accommodating the isolation plate 7 and the test lamp 8.

[0032] Each corrosion resistance testing assembly 5 includes two sealing plugs 501, each screwed onto both ends of a test tube 6. One of the sealing plugs 501 coaxially extends a circulation tube 502 into the inner cavity of the test tube 6, and the end of the circulation tube 502 connected to the sealing plug 501 has several through holes. A drive impeller 503 is installed inside the circulation tube 502. A battery 504 coaxially extends from one of the sealing plugs 501, and a solution flow channel exists between the battery 504 and the circulation tube 502. During light exposure testing, the test tube 6 is filled with a corrosive solution, which is the liquid that the test tube 6 will actually transport during use. Powered by the battery 504 and driven by the drive impeller 503, the corrosive solution in the test tube 6 flows from the axis of the test tube 6 to the tube wall and then back to the axis, thus circulating. The drive impeller 503 can be activated by a standard waterproof switch or a Bluetooth switch.

[0033] Each rotation limiting assembly 3 includes a mounting base 301 connected to the mounting plate 2. Two horizontally arranged fixed wheels 302 are rotatably mounted at the bottom of the vertical notch of the mounting base 301. Two movable seats 303 are elastically and horizontally slidably mounted on both sides of the top of the notch of the mounting base 301, and the two movable seats 303 are mirror images of each other. A movable wheel 304 is rotatably mounted on one end of each movable seat 303 extending out of the mounting base 301. A spring 305 is connected to the square end of each movable seat 303, and the spring 305 is also connected to the mounting base 301. Several first mounting bolts 306 penetrate the bottom of the mounting base 301, and the first mounting bolts 306 are threadedly connected to the mounting plate 2. In the embodiment shown in the attached figure, two first mounting bolts 306 are provided. After the rotating shaft of the sealing shaft plug 501 is inserted into the notch of the mounting base 301, the rotating shaft is lifted by the two fixed wheels 302, and the top of the rotating shaft is elastically compressed by the two movable wheels 304, causing the sealing shaft plug 501 to rotate only around its own axis.

[0034] Each drive assembly 4 includes a first gear 402 coaxially fixedly connected to the rotating shaft of the adjacent sealing plug 501. The first gear 402 meshes with a second gear 403, and the second gear 403 is coaxially fixedly connected to a drive motor 401. Second mounting bolts 404 pass through each of the four corners of the drive motor 401, and the second mounting bolts 404 are threadedly connected to the mounting plate 2. The diameter of the first gear 402 is larger than the diameter of the second gear 403, which is used to reduce the speed at the output end of the drive motor 401, allowing the test tube 6 to rotate slowly for light aging testing.

[0035] Working principle:

[0036] In use, the test tube 6 is filled with a corrosive solution, and a sealing plug 501 is tightened at each end of the test tube 6. Then, the rotating shaft of the sealing plug 501 is inserted into the corresponding mounting seat 301 notch, so that the rotating shaft of one sealing plug 501 is surrounded by two adjacent fixed wheels 302 and two moving wheels 304. The first gear 402 meshes with the adjacent second gear 403. Then, the isolation plate 7 is inserted between the test tubes 6, and the test lamps 8 with different light intensities are turned on. Under the deceleration drive of the drive motor 401 through the first gear 402 and the second gear 403, the test tube 6 rotates slowly to perform the light aging test.

[0037] During the light aging test, driven by the impeller 503, the corrosive solution in the test tube 6 flows from the axis of the test tube 6 to the tube wall and then back to the axis, thus circulating to test the corrosion resistance of the test tube 6.

[0038] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
