[0032] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the brine system water pipe corrosion resistance testing device of the utility model in conjunction with the accompanying drawings.

[0033] like Figure 1-Figure 7As shown, a brine system water pipe corrosion resistance testing device of the utility model comprises a protective chassis 100 for shielding internal test objects, a test chamber 120 for immersion test of water pipes is arranged inside the protective chassis 100, a lifting frame 200 for placing brine system water pipes is movably installed inside the test chamber 120, clamping units 300 for fixing the water pipes are movably installed on both sides of the lifting frame 200, and a spray frame 400 for spraying the water pipes at the lower end is movably installed inside the protective chassis 100.

[0034] A support frame 140 is fixedly installed inside the protective chassis 100 for support, and the test chamber 120 is installed on the upper end of the support frame 140. A lifting cylinder 130 for controlling the lifting frame 200 to move up and down is movably installed on the upper end of the support frame 140. The upper and lower ends of the lifting cylinder 130 are respectively connected to the support frame 140 and the lifting frame 200 through connecting shafts. The lifting frame 200 includes a frame body 210 installed in the test chamber 120 for lifting and lowering, and a limit bar 220 installed in the frame body 210 for clamping and fixing. The clamping unit 300 is slidably installed in the limit bar 220, and the limit bar 220 can be fastened by screws. A rotating frame 230 for driving the frame body 210 to lift is rotatably installed on one side of the frame body 210 through an installation axis, and the other end of the rotating frame 230 is installed on the upper end of the support frame 140. A support rod 240 for supporting them is fixedly installed in the middle of the frame body 210 and the rotating frame 230, and the lower end of the lifting cylinder 130 is connected to the support rod 240.

[0035] When the water pipe needs to be tested, the water pipe is placed on the upper end of the table of the frame 210. After the planned time is up, the lifting cylinder 130 is retracted, thereby driving the frame 210 at the lower end to be lifted upward, and then the water pipe at the upper end of the frame 210 is driven to rise, so that the corrosion condition of the water pipe can be observed, which is convenient for corrosion resistance testing of the brine system water pipe. The performance of the water pipe can be tested by controlling the content of the test liquid inside the test chamber 120.

[0036] The clamping unit 300 includes a clamping arm 310 for clamping the water pipe and a rotating rod 330 installed on one side of the clamping arm 310 for driving the clamping arm 310 to rotate. A transmission gear 340 for driving the rotating rod 330 to rotate and swing is fixedly installed on one end of the rotating rod 330. The transmission gears 340 corresponding to the two sets of rotating rods 330 for clamping are meshed for transmission, and are supported by an auxiliary rod movably installed internally. A driving gear 350 for driving the driving gear 340 to rotate is meshed and installed on one side of the transmission gear 340. The driving gear 350 is driven to rotate by a driving device 370 fixedly installed on one side. The driving device 370 is composed of a driving motor and a reduction device. The transmission gear 340 and the rotating rod 330 are both movably installed inside the fixed frame 380. The driving device 370 is installed on one side of the fixed frame 380. The position of the fixed frame 380 is fixed by a sliding frame 360 ​​on one side of the fixed frame 380.

[0037] When the water pipe is immersed in a test, the driving device 370 can be controlled to drive the driving gear 350 to rotate, thereby driving the transmission gear 340 installed in meshing on one side to rotate, and then driving the rotating rod 330 fixedly installed on one side to push the clamping arm 310 to rotate, thereby driving the clamping arm 310 to rotate and clamp the water pipe, so as to fix the water pipe when the water pipe is subjected to a corrosion resistance test, thereby preventing the water pipe from floating or shifting and affecting the test.

[0038] An anti-skid pad 320 is installed inside the clamping arm 310 to prevent the water pipe from slipping, so that the clamping arm 310 can detect the object to be detected.

[0039] The lower end of the sliding frame 360 ​​is slidably installed in the groove opened at the upper end of the limiting strip 220 through the limiting slider 361, and can be fixed by screws. The upper end of the sliding frame 360 ​​and the fixed frame 380 are rotationally fastened by the fastening screw 362. When fixing water pipes of different lengths, the sliding frame 360 ​​can be moved inside the limiting strip 220, and the relative distance between the clamping units 300 on both sides can be adjusted, which is more flexible to use.

[0040] A placement rack 260 is placed at the upper end of the frame 210 for supporting the placement of water pipes. The placement rack 260 is fixed by a fastening piece 250 fixedly arranged on the upper surface of the frame 210. When placing the water pipes, the placement rack 260 can be installed and fixed on the upper end of the fastening piece 250, which is convenient for supporting the water pipes or slices at the upper end, and can also limit the limit strip 220 installed at the lower end.

[0041] The inner side wall of the protective chassis 100 is provided with a water pipe 150 for water filling test on the water pipe. The water pipe 150 is respectively arranged on the head and tail sides of the water pipe and transported by a water pump. During the corrosion resistance test, the head and tail sides of the water pipe to be tested can be connected to the water pipe 150 respectively, and brine test liquid is introduced into the water pipe to test the performance of the water pipe.

[0042] A spray rack 400 for spraying the water pipe at the lower end is fixedly installed at the upper end of the support frame 140. When the spray rack 400 is in operation, the internal liquid is blocked by the opening and closing cover 110 rotatably installed on the outside of the protective chassis 100. When the water pipe is inspected, the water pipe at the lower end can be sprayed and tested by simulating rainy days and other conditions. The opening and closing cover 110 can ensure that the spray liquid does not exceed the spraying range of the protective chassis 100.

[0043] The spray rack 400 includes a liquid pipe 410 for passing the test liquid and spray heads 430 installed on both sides of the liquid pipe 410 for easy spraying. The diameter of the pipe of the liquid pipe 410 gradually decreases from one end. The liquid pipe 410 is installed on the upper end of the support frame 140 through a connecting frame 420 fixedly installed at the upper end. The reduction in the diameter of the water pipe can ensure that the water spraying pressure is sufficient to spray the objects at the lower end.

[0044] The working principle of a brine system water pipe corrosion resistance testing device is as follows: when the water pipe needs to be tested, the water pipe is placed on the upper end of the table of the frame 210. After the planned time is up, the lifting cylinder 130 is retracted, thereby driving the frame 210 at the lower end to be lifted upward, and then the water pipe at the upper end of the frame 210 is driven to rise, so that the corrosion condition of the water pipe can be observed, which is convenient for the corrosion resistance test of the brine system water pipe. The performance of the water pipe can be tested by controlling the content of the test liquid in the test chamber 120.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
