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.

[0021] The utility model provides Figure 1-4A motor for a cooling tower fan with a moisture-proof structure is shown, comprising a body 1, a junction box 2 is arranged on the top of the body 1, a box cover 3 is arranged on the top of the junction box 2, a sealing member is arranged at the connection between the junction box 2 and the box cover 3, a dehumidification component for absorbing moisture is arranged on the top of the junction box 2, the dehumidification component comprises a moisture absorbing plate 9 arranged on the top of the junction box 2, and a positioning member 5 is arranged on the top of the box cover 3; the positioning member 5 comprises a fixed frame 503 fixedly connected to the top of the box cover 3, a mesh plate 502 for limiting the movement of the moisture absorbing plate 9 is inserted and connected inside the fixed frame 503, a mounting frame 501 is fixedly connected to the bottom of the mesh plate 502, a clamping member 6 for fixing the position of the mounting frame 501 is arranged at the connection between the mounting frame 501 and the fixed frame 503, and the mounting frame 501 is inserted and connected to the inner wall of the top of the box cover 3.

[0022] It should be noted that the machine body 1, junction box 2 and box cover 3 are existing fans; a device is provided between the junction box 2 and the box cover 3 to prevent moisture or other objects from entering the interior of the junction box 2, and the junction box 2 and the box cover 3 are fixed by bolts; the material of the moisture absorbing plate 9 can be a desiccant, and the moisture in the junction box 2 is absorbed by the desiccant when in use; the fixing frame 503 is fixedly connected to the top of the box cover 3, and a hole compatible with the mounting frame 501 is opened in the middle of the box cover 3, and when it is needed, the fixing frame 503 can be fixedly connected to the top of the box cover 3, and a hole compatible with the mounting frame 501 is opened in the middle of the box cover 3. When the position of the desiccant plate 9 is fixed, the desiccant plate 9 is first inserted into the interior of the fixed frame 503, and then the mounting frame 501 drives the mesh plate 502 to penetrate into the interior of the fixed frame 503, and the mounting frame 501 and the fixed frame 503 are fixed by the clamping member 6, and the position of the desiccant plate 9 is fixed by the mesh plate 502 and the fixed frame 503 in fixed position; the mesh plate 502 is provided with a hole with a diameter of 0.05 to 0.1 on the plate, which is used for air to pass through the mesh plate 502 and complete the desiccant work through the desiccant plate 9.

[0023] Specifically, the sealing member includes a sealing ring 4 disposed on the top end of the junction box 2 , and the sealing ring 4 is fixedly connected to the bottom end of the mounting frame 501 .

[0024] It should be noted that the provided sealing ring 4 is fixed to the bottom end of the mounting frame 501 by bonding or other means, and is fixed to the bottom of the box cover 3 through the mounting frame 501. When the box cover 3 and the junction box 2 are fixed, the sealing ring 4 is located between the box cover 3 and the junction box 2. When the box cover 3 and the junction box 2 are fixed by bolts, the sealing ring 4 is squeezed and deformed by the box cover 3 and the junction box 2, and the gap between the junction box 2 and the box cover 3 is filled by the deformed sealing ring 4, thereby sealing the connection between the junction box 2 and the box cover 3.

[0025] Specifically, the clamping member 6 includes clamping blocks 601 symmetrically inserted and connected on both sides of the fixed frame 503, and clamping holes 602 are symmetrically opened on both sides of the mounting frame 501. The clamping blocks 601 are clamped inside the clamping holes 602. One side of the clamping block 601 is provided with a pushing member 7 for pushing the clamping block 601 to move. The pushing member 7 includes a pushing block 701 fixedly connected to one side of the clamping block 601, and one side of the pushing block 701 is fixedly connected to an elastic block 702, and the horizontal longitudinal section of the elastic block 702 is set to a trapezoid. A plurality of fixed blocks 8 are symmetrically arranged on both sides of the fixed frame 503, and the fixed blocks 8 are fixedly connected to the top of the box cover 3. A cavity 703 is opened in the middle of the fixed block 8, and the pushing block 701 and the elastic block 702 are both inserted and connected inside the cavity 703.

[0026] It should be noted that the provided mounting frame 501 is adapted to the provided fixed frame 503. When the mounting frame 501 is inserted into the bottom of the fixed frame 503 during use, the mounting frame 501 cannot shake inside the fixed frame 503. The provided clamping block 601 is used to block the movement of the mounting frame 501. When the position of the mounting frame 501 needs to be fixed, the mounting frame 501 is first inserted into the interior of the fixed frame 503, and then the clamping block 601 is inserted into the clamping hole 602 opened on the mounting frame 501. The blocking of the clamping block 601 prevents the mounting frame 501 from moving, thereby fixing the position of the mounting frame 501. One side of the provided clamping block 601 is an inclined surface. When the mounting frame 501 is inserted into the interior of the fixed frame 503, the top of the mounting frame 501 is first the joint of the oblique sides of the clamping block 601, and the clamping block 601 is pushed to the side away from the mounting frame 501 by the extrusion of the mounting frame 501. When the clamping hole on the mounting frame 501 is pressed, the clamping block 601 is pushed to the side away from the mounting frame 501. When 602 is aligned with the card block 601, the card block 601 is pushed by the pushing member 7, so that the card block 601 is pushed into the inside of the card hole 602, so that the position of the mounting frame 501 is fixed by the card block 601. When the mounting frame 501 needs to be disassembled, the card block 601 is directly pressed out of the card hole 602, and the mounting frame 501 is pulled out from the fixed frame 503; the elastic block 702 is made of rubber material, which will be deformed when squeezed, and when the squeeze is lost, it will restore the deformation and push the pushing block 701 on one side of the card block 601 to one side of the card block 601 by restoring the deformation. A hole for the card block 601 to pass through the cavity 703 is opened on one side of the cavity 703. The hole is adapted to the card block 601, and its horizontal longitudinal section is smaller than the horizontal longitudinal section of the pushing block 701, so that the pushing block 701 cannot pass through the cavity 703 through the hole, thereby limiting the moving distance of the card block 601 by limiting the moving pushing block 701.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
