[0003] When the device is in use, it not only needs to rely on multiple sets of cooling fans and exhaust fans for heat dissipation, which increases the use cost of the device, but also requires manual pulling out of the moisture-proof agent storage frame to replace the moisture-proof agent, which is more labor-intensive. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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] Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0022] refer to Figure 1-Figure 5 The utility model discloses an electrical safety protection device for electrical equipment, including a protection box 1 with heat dissipation ports 2 on the top and bottom, the heat dissipation ports 2 being arranged at the center of the top and bottom of the protection box 1, a heat dissipation assembly 3 being arranged inside the protection box 1 and at the heat dissipation port 2, the heat dissipation assembly 3 comprising a self-locking double-output shaft motor 301, the self-locking double-output shaft motor 301 being fixed on the side wall of the protection box, the top and bottom output ends of the self-locking double-output shaft motor 301 being connected with a rotating shaft 302, the rotating shaft 302 being arranged in a vertical direction, and the other ends of the two rotating shafts 302 being arranged with a first pulley 303; a rotating rod 306 extending into the protection box 1 is arranged at the heat dissipation port 2, the rotating rod 306 being rotatably connected to the protection box 1, and can be fixed to the protection box through a bearing. The end of the rotating rod 306 outside the protection box 1 is provided with a second pulley 304, and the second pulley 304 is connected to the first pulley 303 through a transmission belt 305. The end of the rotating rod 306 extending into the protection box 1 is provided with a plurality of fan blades 307 in the circumferential direction. It should be noted that the fan blades and the rotating rod are provided at the top and bottom of the protection box, and are connected by a transmission belt through the pulley on the rotating rod and the pulley on the rotating shaft at the corresponding position. When the motor is started, the fan blades at the two positions can be driven to rotate at the same time, so as to dissipate heat inside the protection box.

[0023] Furthermore, the heat dissipation openings 2 are arranged radially and around the rotating rod 306 so that the fan blades correspond to the heat dissipation openings to enhance the heat dissipation effect.

[0024] When heat dissipation protection is required for the electrical equipment inside the protection box 1, the self-locking double-output shaft motor 301 is started to rotate forward (the one-way bearing 507 does not transmit power at this time) to drive the rotating shaft 302 and the first pulley 303 to rotate. The first pulley 303 drives the second pulley 304, the rotating rod 306, and the fan blade 307 to rotate with the help of the transmission belt 305. At the same time, the heat dissipation protection of the electrical equipment is completed through the heat dissipation port 2, and energy-consuming equipment is reduced, thereby reducing the use cost of the device.

[0025] Furthermore, the inner bottom of the protection box 1 is laterally provided with air permeable plates 4 parallel to each other, and a drying component 5 is provided between the air permeable plates 4, so as to keep the inside of the protection box dry.

[0026] Further, the drying component 5 includes a moisture-proof agent box 509, which is arranged between the air-permeable plates 4 and slidably connected thereto. A reciprocating screw 508 is provided on one side of the moisture-proof agent box 509, and the reciprocating screw 508 is threadedly connected to the moisture-proof agent box 509. One end of the reciprocating screw 508 facing the inside of the protection box passes through the protection box and is fixed with a fourth bevel gear 506 through a one-way bearing 507, and the reciprocating screw 508 is rotatably connected to the protection box. A transmission rod 503 is provided between the reciprocating screw 508 and the rotating shaft 302, and a mounting block 504 is rotatably connected to the middle position of the transmission rod 503, and the mounting block 504 is fixed on the protection box 1. The transmission rod is provided through the mounting block, and the mounting block and the transmission rod can be rotatably connected through a bearing, or a gap can be provided to realize the rotation of the transmission rod. The transmission rod 503 has a third bevel gear 505 meshing with the fourth bevel gear 506 at one end, and a second bevel gear 502 meshing with the first bevel gear 501 sleeved on the rotating shaft 302 at the other end. The first bevel gear 501 is sleeved and fixed on the rotating shaft below the self-locking double-output shaft motor 301, and meshes with the second bevel gear 502, so that when the rotating shaft 302 rotates, the reciprocating screw rotates under the cooperation of the bevel gear, thereby driving the moisture-proof agent box to reciprocate.

[0027] When it is necessary to add moisture-proof agent, the self-locking double-output shaft motor 301 is started to reverse (the one-way bearing 507 is driven at this time) to drive the rotating shaft 302, the first bevel gear 501, the second bevel gear 502, the transmission rod 503, the third bevel gear 505, the fourth bevel gear 506, the one-way bearing 507, and the reciprocating screw 508 to rotate. The reciprocating screw 508 drives the moisture-proof agent box 509 to gradually extend along the sliding rod 510 to facilitate the replacement of the moisture-proof agent inside the moisture-proof agent box 509, which saves manpower.

[0028] Furthermore, in order to ensure the stability of the desiccant box 509 during movement, a slide bar 510 is provided on the other side of the desiccant box 509, and the slide bar 510 is parallel to the reciprocating screw rod 508. The slide bar 510 is slidably connected to the desiccant box 509, and one or both ends of the slide bar 510 are fixed to the protection box 1.

[0029] The utility model is used as an electrical safety protection device for electrical equipment. When in use, the electrical equipment to be protected is first placed on the air-permeable plate 4 and the protection box 1 is closed for protection. When heat dissipation protection is required for the electrical equipment inside the protection box 1, the self-locking double-output shaft motor 301 is started to rotate forward (the one-way bearing 507 does not transmit power at this time) to drive the rotating shaft 302 and the first pulley 303 to rotate. The first pulley 303 drives the second pulley 304, the rotating rod 306, and the fan blades 307 to rotate with the help of the transmission belt 305, and at the same time, the heat dissipation protection of the electrical equipment is completed through the heat dissipation port 2.

[0030] When it is necessary to add moisture-proof agent, the self-locking double-output shaft motor 301 is started to reverse (the one-way bearing 507 is driven at this time) to drive the rotating shaft 302, the first bevel gear 501, the second bevel gear 502, the transmission rod 503, the third bevel gear 505, the fourth bevel gear 506, the one-way bearing 507, and the reciprocating screw 508 to rotate. The reciprocating screw 508 drives the moisture-proof agent box 509 to reciprocate along the sliding rod 510 to a suitable position to facilitate the replacement of the moisture-proof agent inside the moisture-proof agent box 509, thereby completing the moisture-proof protection of the electrical equipment.

[0031] It should be emphasized that the one-way bearing 507 is a special type of bearing, also called a one-way roller bearing or a one-way thrust bearing, which is usually used in mechanical systems that only allow torque or rotation to be transmitted in one direction. The self-locking dual-output shaft motor 301 is preferably a device with model RE 35 of Maxon (Switzerland).

[0032] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0033] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
