Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: Figure 1-5 As shown, the utility model provides an evaporative condenser protection device, including a box body 1, mounting grooves 2 are provided on both sides of the bottom end of the box body 1, a filter plate 3 is placed inside the mounting groove 2, through grooves 4 are provided at the four corners of the top end of the filter plate 3, and clamping grooves 5 perpendicular to the through grooves 4 are provided at the four corners of the top end of the filter plate 3, a clamping assembly is provided between the filter plate 3 and the box body 1, an axial flow fan 16 is fixedly installed at the top end of the box body 1, and a protection assembly is provided at the top end of the box body 1 and on the outside of the axial flow fan 16.

[0021] The clamping assembly includes a fixed cylinder 6, which is fixedly connected to the inner wall of the box body 1 near the through groove 4. A slider 7 is slidably clamped inside the fixed cylinder 6, and a telescopic rod 8 is fixedly connected to one side of the slider 7. The end of the telescopic rod 8 away from the slider 7 extends to the outside of the box body 1 and is fixedly connected to a clamping block 10. The clamping blocks 10 are movably clamped inside the clamping slot 5.

[0022] By adopting the above technical solution, when installing the filter plate 3, the four through grooves 4 are made to correspond to the positions of the clamping block 10, and then the clamping block 10 is moved through the through groove 4. By pulling the clamping block 10, the slider 7 and the telescopic rod 8 are moved to the outside of the box body 1, and the spring 9 is squeezed. When the clamping block 10 completely passes through the through groove 4, the clamping block 10 is rotated 90 degrees and the position of the clamping block 10 is made to correspond to the position of the clamping slot 5, and then the clamping block 10 is released. The elastic force of the spring 9 is used to clamp the clamping block 10 to the inside of the clamping slot 5. The operation is repeated, and the clamping blocks 10 at the four corners are respectively clamped to the inside of the corresponding clamping slot 5, thereby completing the installation operation of the filter plate 3.

[0023] The protective assembly includes four fixed blocks 11, which are fixedly connected at the four corners of the top of the box body 1. A bidirectional screw rod 12 is rotatably connected between two corresponding fixed blocks 11. The outer side of the bidirectional screw rod 12 is threadedly connected to symmetrically distributed moving blocks 13, and the top of the moving blocks 13 is fixedly connected to a protective cover 15.

[0024] By adopting the above technical solution, by rotating the bidirectional screw 12, the two moving blocks 13 are driven to move toward the side away from or toward each other at the same time, thereby driving the protective cover 15 to move toward the side away from or toward each other. When the axial flow fan 16 is needed, the protective cover 15 is opened, and when the axial flow fan 16 is not needed, the protective cover 15 is closed.

[0025] A spring 9 is arranged between one side of the sliding block 7 close to the clamping block 10 and the inner wall of the fixing tube 6 , and the spring 9 is movably sleeved on the outer side of the telescopic rod 8 .

[0026] By adopting the above technical solution and providing the spring 9, the slider 7 can be reset, and the elastic force of the spring 9 can be used to increase the stability of the structure.

[0027] A guide rod 17 is fixedly connected between the two corresponding fixing blocks 11 , and the protective cover 15 is slidably engaged with the outer side of the guide rod 17 .

[0028] By adopting the above technical solution and providing the guide rod 17 , the lateral movement of the protective cover 15 can be guided.

[0029] A servo motor 14 is fixedly mounted on one side of the fixed blocks 11 away from the bidirectional screw rod 12 , and a driving end of the servo motor 14 is fixedly connected to the bidirectional screw rod 12 .

[0030] By adopting the above technical solution and providing the servo motor 14 , it is convenient to drive the bidirectional screw rod 12 to rotate, thereby realizing the opening and closing operation of the protective cover 15 .

[0031] Working principle: When using the evaporative condenser, the air inlet end of the evaporative condenser is protected by setting the filter plate 3. When installing the filter plate 3, the four through slots 4 are made to correspond to the positions of the clamping block 10, and then the clamping block 10 is made to movably penetrate the through slot 4. By pulling the clamping block 10, the slider 7 and the telescopic rod 8 are driven to move to the outside of the box body 1, and the spring 9 is squeezed. When the clamping block 10 completely penetrates the through slot 4, the clamping block 10 is rotated 90 degrees and the position of the clamping block 10 is made to correspond to the position of the clamping slot 5, and then the clamping block 10 is released. The elastic force of the spring 9 is used to make the clamping block 10 clamped to the inside of the clamping slot 5. Repeat this operation to clamp the clamping blocks 10 at the four corners to the inside of the corresponding clamping slot 5, thereby completing the installation operation of the filter plate 3. Similarly, it is convenient to disassemble and replace the filter plate 3.

[0032] The bidirectional screw rod 12 is driven to rotate by the servo motor 14, and at the same time, the two moving blocks 13 are driven to move toward the side away from or toward each other, thereby driving the protective cover 15 to move toward the side away from or toward each other. When the axial flow fan 16 is needed, the protective cover 15 is opened, and when the axial flow fan 16 is not needed, the protective cover 15 is closed.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
