[0002] Electrical cabinets are devices used to protect, control, and distribute electricity. They are widely used in various industrial, commercial, and residential power systems. They distribute electricity to various loads or equipment through circuit breakers and contactors, control the start and stop status of motors and other equipment, and perform remote operations through relays and contactors. During operation, electrical cabinets need to consider heat dissipation.

[0003] Heat dissipation on the top of the electrical cabinet is an important part of ensuring the stable operation of the equipment inside the cabinet. Factors such as heat generation of the equipment inside the cabinet, environmental conditions, and cost must be considered to ensure that the heat dissipation design can meet actual needs and must be maintained and inspected regularly.

[0004] Existing heat dissipation methods generally adopt the method of opening heat dissipation holes or top heat dissipation, and utilizing natural wind convection to dissipate heat. However, the lack of a protective device during top heat dissipation will damage the cooling fan, thereby reducing the heat dissipation efficiency of the electrical cabinet and shortening its service life. Therefore, a top heat dissipation waterproof protective device is proposed to solve the above problem. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 、 Figure 2 and Figure 4The utility model provides an embodiment of a top heat dissipation waterproof protection device, comprising a base 1, a heat dissipation fan 4 is fixedly connected to the middle part of the top wall of the base 1, and a connecting seat 3 is fixedly installed on the inner bottom wall of the heat dissipation fan 4. A protective shell 5 is provided on the top of the base 1, and a waterproof plate 6 is fixedly connected to the bottom of the outer wall of the protective shell 5. The left and right sides of the protective shell 5 are fixedly connected to the mounting shell 7. The inner wall of the mounting shell 7 is rotatably connected to a threaded rod 8, and the rear end of the threaded rod 8 is fixedly connected to a knob 9. The outer wall of the threaded rod 8 is threadedly connected to a movable plate 11. The left and right ends of the front side of the movable plate 11 are fixedly connected to a clamping plate 12. Limiting grooves 13 are provided on the left and right sides of the top wall of the base 1, and the front sides of the left and right ends of the inner wall of the base 1 are fixedly connected to a fixing plate 14. The left and right ends of the rear side of the fixing plate 14 are provided with a clamping groove 15. The front ends of multiple clamping plates 12 are respectively engaged with the corresponding clamping grooves 15. A plurality of guide mechanisms 2 are equidistantly provided on the top wall of the heat dissipation fan 4. The guide mechanism 2 is used to improve the waterproof effect of the device.

[0033] Specifically, by using the protective shell 5, the cooling fan 3 can be protected. The outer wall of the protective shell 5 is designed with multiple holes. These holes can not only ensure the normal heat dissipation of the cooling fan 3, but also effectively prevent small creatures such as flying insects from entering, thereby avoiding possible damage to the fan. The addition of the waterproof plate 6 further improves the waterproof effect of the entire device. By turning the knob 9, the threaded rod 8 can be driven. The rotation of the threaded rod 8 will drive the movable plate 11, causing it to rotate and move. The limit groove 13 limits the rotation of the movable plate 11 so that it will not follow the threaded rod 8 rotates together, so that the movable plate 11 can only move along the axis, thereby realizing the separation of the movable plate 11 and the engaging plate 12 from the fixed plate 14. When the movable plate 11 and the engaging plate 12 are separated from the fixed plate 14, the locking state between the engaging plate 12 and the engaging groove 15 is released, so that the entire device can be disassembled. When the cooling fan 3 needs to be maintained or replaced, the protective shell 5 can be quickly removed, avoiding possible damage to the cooling fan 3 in the absence of a protective device, which not only increases the protection effect of the device, but also increases its service life, ensuring the stable operation of the equipment.

[0034] Reference Figure 1 、 Figure 3 and Figure 5 The guide mechanism 2 includes a plurality of electric telescopic rods 201, the bottom ends of which are rotatably connected to the four sides of the top wall of the cooling fan 4. The top wall of the electric telescopic rod 201 is rotatably connected to a rotating column 202, one side of the rotating column 202 is rotatably connected to an arc plate 203, and the inner wall of the arc plate 203 is fixedly connected to a plurality of guide shells 204 at equal intervals. One side of the arc plate 203 is rotatably connected to the outer wall of the connecting base 3 through a hinge 205.

[0035] Specifically, by starting the electric telescopic rod 201, the arc plate 203 is driven by displacement. Subsequently, under the restriction and guidance of the hinge 205, the arc plate 203 and the rotating column 202 rotate in coordination, so that the arc plate 203 can complete the angle adjustment. Under the guidance of multiple guide shells 204, the airflow generated by the cooling fan 3 can be effectively guided and redirected. In this way, the airflow can achieve the effect of lifting upward, and then be blown out through the multiple holes of the protective shell 5, reducing the probability of water droplets entering, thereby significantly improving the waterproof effect of the equipment.

[0036] Reference Figure 1 、 Figure 4 and Figure 5 The guide mechanism 2 includes a plurality of arc grooves 206, which are equidistantly arranged on the top of the corresponding arc plate 203; a control switch 19 is fixedly connected to the front side of the base 1, and the control switch 19 is electrically connected to the cooling fan 4 and the electric telescopic rod 201 respectively; the four corners of the bottom wall of the protective shell 5 are fixedly connected to the connecting columns 17, and the front and rear sides of the top wall of the base 1 are fixedly connected to two connecting grooves 18, and the bottom ends of the plurality of connecting columns 17 are respectively engaged with the corresponding connecting grooves 18;

[0037] Specifically, the toughness of the arc plate 203 is improved by using multiple arc grooves 206, and the control switch 19 is electrically connected to the cooling fan 4 and the electric telescopic rod 201 respectively, so that the control switch 19 can complete the opening and closing of the device, and the bottom ends of multiple connecting columns 17 are respectively engaged with the corresponding connecting grooves 18, so as to improve the stability of the protective shell 5 and the base 1.

[0038] Reference Figure 1 and Figure 4 The outer walls of the two knobs 9 are fixedly connected with a plurality of protrusions 10, and the plurality of protrusions 10 are arranged in an equidistant ring; the left and right sides of the top wall of the base 1 are fixedly connected with rubber gaskets 16, and the rear sides of the plurality of rubber gaskets 16 are provided with grooves; the top wall of the protective shell 5 is provided with inclined surfaces all around, and the two mounting shells 7 are symmetrically designed;

[0039] Specifically, the anti-slip effect of the knob 9 is improved by multiple protrusions 10, the wear of the mounting shell 7 and the base 1 is reduced by the rubber gasket 16, and the pressure resistance of the top of the protective shell 5 is improved by providing inclined surfaces on all sides of the top wall of the protective shell 5.

[0040] Working principle: When starting to use, the cooling fan 3 can be protected by the protective shell 5. The multiple holes on the outer wall of the protective shell 5 prevent the entry of flying insects. The waterproof plate 6 improves the waterproof effect. By turning the knob 9, the threaded rod 8 drives the movable plate 11, and the movable plate 11 has a tendency to rotate and displace. Under the rotation restriction of the movable plate 11 by the limit groove 13, the movable plate 11 will not rotate with the threaded rod 8, and the axial displacement is completed, so that the movable plate 11 and the engaging plate 12 are separated from the fixed plate 14, so that the engaging plate 12 is unlocked from the engaging groove 15. By pulling the protective shell 5 upward, the protective shell 5 can be quickly disassembled, and finally avoids the situation where the cooling fan 3 is damaged due to the lack of a protective device, thereby increasing the protection effect of the device and improving the service life.

[0041] And by starting the electric telescopic rod 201, the arc plate 203 is driven to move, and then rotates together with the rotating column 202 under the limited displacement of the hinge 205, so that the arc plate 203 completes the angle adjustment, so that under the guided airflow of multiple guide shells 204, the airflow generated by the cooling fan 3 can be guided and redirected, and then the airflow completes the effect of lifting upward, so that the airflow is blown out through the multiple holes of the protective shell 5, reducing the entry of water droplets, and Genori improves the waterproof effect.
