[0049] After the test cabinet 1 is moved to the designated position by the moving positioning mechanism, the test device 6 is placed inside the test cabinet 1. The connecting pipe 9 is fixed to the water pipe 7 by the fixing mechanism. The water pump draws out cold water and sends it into the test device 6 through a set of connecting pipes 9 and water pipes 7. The test device 6 heats the cold water, and the hot water flows out from another set of water pipes 7 and connecting pipes 9. The display controller 2 monitors and displays data such as liquid flow rate, inlet pressure, outlet pressure, inlet temperature, and outlet temperature during the test.

[0050] In this embodiment, various monitors (not shown in the figure) are used to monitor data such as liquid flow rate, inlet pressure, outlet pressure, inlet temperature, and outlet temperature, and the data is transmitted to the display controller 2.

After reaching the desired position, the grounding sleeve 5 is rotated to make it fit tightly against the ground, thereby fixing the test cabinet 1 and preventing it from shaking or shifting during the test.

[0057] As one embodiment of this utility model, please refer to Figures 3 to 6 The fixing mechanism includes:

[0058] A fixing ring 11 is connected to the outer wall of the water pipe 7. The fixing ring 11 has several sets of L-shaped grooves 12 arranged in a circular pattern with equal spacing.

[0059] The snap-fit ​​folding rod 13 snaps into the L-shaped groove 12 and abuts against the fixing ring 11;

[0065] In this embodiment, the L-shaped groove 12 is composed of a straight groove and an arc groove, and the straight groove and the arc groove are connected.

[0066] When fixing the connecting pipe 9, the worker aligns the connecting pipe 9 with the water pipe 7 and presses it down so that the snap-fit ​​lever 13 passes through the straight groove. Then, the connecting ring 14 is rotated so that the snap-fit ​​lever 13 rotates to snap into the arc groove. Next, the worker rotates the rotating component, which drives the threaded rod 16 to rotate. The threaded rod 16 drives the fixing block 17 to move, thereby driving the connecting pipe 9 to move linearly along the water pipe 7, so that the connecting pipe 9 and the water pipe 7 come into contact and are connected together.

[0067] As one embodiment of this utility model, please refer to Figures 3 to 6 The rotating assembly includes:

[0068] Gear 18 is connected to threaded rod 16;

[0069] Gear ring 19 meshes with gear 18;

[0070] Fixed bending rod 20, one end of which is connected to toothed ring 19;

[0071] The rotating ring 21 is connected to the other end of the fixed folding rod 20 and is rotatably connected to the connecting ring 14.

[0072] The staff rotates the rotating ring 21, which drives the fixed bending rod 20 to rotate. The fixed bending rod 20 drives the gear ring 19 to rotate, which drives the gear 18 to rotate, and the gear 18 drives the threaded rod 16 to rotate.

[0073] As one embodiment of this utility model, please refer to Figure 6 The other end of the connecting pipe 9 is flared and its diameter gradually increases outward. A sealing ring 10 is provided at the connection between the connecting pipe 9 and the water pipe 7 to improve the sealing performance.

[0074] The other end of the connecting pipe 9 is flared and its diameter gradually increases outward. This design facilitates the snap-fit ​​connection with the water pipe 7. A sealing ring 10 is provided at the snap-fit ​​point between the connecting pipe 9 and the water pipe 7 to improve the sealing performance, prevent water leakage during the test, and ensure the smooth progress of the hot and cold cycle test.

[0075] The working principle of this utility model is as follows: The test device 6 is placed inside the test cabinet 1. The operator aligns the connecting pipe 9 with the water pipe 7 and presses it down so that the snap-fit ​​lever 13 passes through the straight groove. Then, the connecting ring 14 is rotated so that the snap-fit ​​lever 13 is engaged with the arc groove. Next, the operator rotates the rotating ring 21, which drives the fixed lever 20 to rotate. The fixed lever 20 drives the gear ring 19 to rotate, which drives the gear 18 to rotate. The gear 18 drives the threaded rod 16 to rotate, which drives the fixed block 17 to move. This causes the connecting pipe 9 to move linearly along the water pipe 7, so that the connecting pipe 9 and the water pipe 7 come into contact and are connected together. The water pump draws cold water through a set of connecting pipes 9 and water pipes 7 and sends it into the test device 6. The test device 6 heats the cold water, and hot water flows out from another set of water pipes 7 and connecting pipes 9. The display controller 2 monitors and displays data such as liquid flow rate, inlet pressure, outlet pressure, inlet temperature, and outlet temperature during the test.
