These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0025] Embodiment 1

[0026] like Figure 1-Figure 3 As shown, a water immersion test device includes a box body 1, an explosion-proof door 3 is installed on one side of the box body 1, and an observation window 31 is opened on the explosion-proof door 3; a water tank 2 is arranged on the inner side of the box body 1, a bracket 4 is arranged above the water tank 2, the lower part of the bracket 4 is connected to a base frame 5, and a clamp assembly 6 for fixing the product is arranged on the base frame 5.

[0027] The explosion-proof door 3 is arranged at the upper part of the outer side of the box body 1, and the water tank 2 is arranged at the lower part of the inner side of the box body 1; the bracket 4 can be lifted and lowered along the Z-axis direction, and the base frame 5 can be rotated around the Y-axis direction. The water tank 2 is used to store the test liquid, and its top is open so that when the bracket 4 moves down, the product can be driven to immerse in the test liquid inside the water tank 2 through the base frame 5.

[0028] As mentioned above, the directions of the three axes X, Y, and Z are perpendicular to each other. The explosion-proof door 3 can be opened and closed on the front of the box body 1, and it has a high-definition observation window 31. The opening and closing of the explosion-proof door 3 can protect the staff from being harmed by the energy fluctuations caused by the failure of the product test, and the situation inside the box body 1 can also be viewed in real time through the observation window 31.

[0029] Furthermore, a first telescopic assembly 8 for driving the bracket 4 to rise and fall is installed on the top of the box body 1 , and an output end of the first telescopic assembly 8 extends into the box body 1 and is connected to the bracket 4 .

[0030] The first telescopic component 8 preferably adopts an electric cylinder, which is fixedly installed on the top of the box body 1, and its output end is located inside the box body 1 and connected to the bracket 4; the output end of the first telescopic component 8 is parallel to the Z-axis direction, so as the first telescopic component 8 is extended and retracted, the bracket 4 can be driven to rise and fall along the Z-axis direction.

[0031] like Figure 3 As shown, the bracket 4 includes a crossbeam 41 parallel to the Y-axis direction, and support rods 42 parallel to the Z-axis direction are fixedly installed at both ends of the crossbeam 41. The lower end of the support rod 42 is rotatably connected to the base frame 5 through a connecting piece 7, and the output end of the first telescopic assembly 8 is fixedly connected to the crossbeam 41. The overall structure of the bracket 4 is an inverted U-shaped structure, which can provide sufficient space for the fixed placement of the product on the base frame 5 while ensuring the connection strength with the base frame 5.

[0032] As mentioned above, the connecting member 7 adopts a T-shaped structure, one end of which is fixedly connected to the base frame 5, and the other end is rotatably connected to the support rod 42, and a second telescopic component 9 for driving the base frame 5 to rotate around the Y-axis direction is provided between the support rod 42 and the connecting member 7.

[0033] The second telescopic assembly 9 preferably adopts a cylinder, and its two ends are rotatably connected to the connecting member 7 and the support rod 42 respectively; based on the connection relationship between the connecting member 7 and the base frame 5 and the support rod 42, when the second telescopic assembly 9 is extended and retracted, the base frame 5 will be driven by the connecting member 7 to swing relative to the support rod 42, and the axis direction of the swing is parallel to the Y axis. The base frame 5 can drive the product to swing in the water tank 2 by rotating around the Y axis, making the product immersion test more comprehensive.

[0034] like Figure 1-Figure 2 As shown, the inner side of the box body 1 is also provided with a guide groove 11 corresponding to the number and position of the support rods 42, and one side of the support rod 42 is slidably embedded in the guide groove 11. The guide groove 11 is made of stainless steel to simulate a linear guide mechanism, so that the bracket 4 can realize the up and down lifting process along the track, thereby reducing its production cost.

[0035] In addition, a control box for controlling the operation of the device is provided on the top of the box 1, and a touch screen integrated machine and a rotary switch are provided on the control box; universal wheels are provided at the bottom of the box 1 to facilitate the transportation and movement of the device.

[0036] Working principle:

[0037] (1) First, open the explosion-proof door 3, manually place the product on the base frame 5, use the clamp assembly 6 to fix and clamp the product, and then close the explosion-proof door 3;

[0038] (2) Turn on the power switch. The light will turn on when the switch is turned on. Click the button to enter the function interface. Click "Settings" to enter the interface, set the soaking height, and select the soaking time.

[0039] (3) After the height and immersion time are selected, click "Test" to enter the test interface, and then click the "Start" button; the first telescopic component 8 pushes the bracket 4 and the base frame 5 downward to the set height position, and the clamp component 6 brings the product into the test liquid in the water tank 2. The test liquid here is mostly water. After it is in place, the bracket 4 stops moving and the product starts to be tested. After the set time is reached, the first telescopic component 8 drives the bracket 4 to move upward to the origin position, and the clamp component 6 brings the product out of the water with the base frame 5. At this time, the immersion test ends;

[0040] (4) After the test results come out, click "Save" to save the test setting parameters and test results.

[0041] Among them, if it is a salt water immersion test, after the end, the bottom valve of the equipment needs to be opened, the pump body needs to be connected, and the salt water needs to be discharged before the next purified water immersion test can be carried out.

[0042] Embodiment 2

[0045] When placing the product, first place the product on the middle beam 63, then put the pressing block 65 on the guide rod 64 and press it down on the product, then use a nut or other fastener to screw it on the guide rod 64 to lock the pressing block 65, so that it completes the locking of the product.

[0046] In order to facilitate locking of the product, the device is provided with two clamp assemblies 6, and the two clamp assemblies 6 are symmetrically distributed on the base frame 5; the two clamp assemblies 6 can lock and fix the two ends of the product respectively, such as a balancing car, and the relative horizontal distance between the two clamp assemblies 6 can be adjusted according to the specifications of the product.

[0047] Furthermore, a plurality of positioning holes 66 are equidistantly formed at both side edges of the base frame 5 along the Y-axis direction, and mounting holes 67 that can overlap with the positioning holes 66 are formed on the bottom beam 61 .

[0048] The bottom beam 61 and the base frame 5 can be fixedly connected by fasteners such as bolt assemblies or screws, that is, the fasteners pass through the mounting holes 67 and the positioning holes 66 in sequence to achieve the positioning and locking of the bottom beam 61 at this position; if the position needs to be adjusted, it is only necessary to align the mounting holes 67 on the bottom beam 61 with different positioning holes 66, and then connect them by fasteners. This structure can greatly improve the scope of application of the device.
