[0002] Electrical instruments are devices that apply electrical engineering technology to instruments. Data is fed back to the control unit through sensing equipment. The control unit controls the digital display device to display the data. Electrical instruments may be placed indoors or outdoors. In order to increase the service life of electrical instruments, electrical instruments are usually placed in protective shells for protection. However, most protective shells are now often set to be airtight. Electrical instruments will emit heat during operation, resulting in the airtight protective shell being difficult to dissipate the heat emitted by the electrical instrument during operation. In addition, protective shells with heat dissipation ports are difficult to protect against rainwater, resulting in rainwater easily entering the protective shell through the heat dissipation ports, making it easy for the heat in the protective shell or the rainwater entering the protective shell to affect the electrical instrument equipment, thereby reducing the service life of the electrical instrument.

[0003] For example, the existing Chinese publication number is: CN211717475U, an electrical instrument protection device, which: "comprises an outer box body, the upper end of the outer box body is rotatably mounted with a box cover through a hinge, the middle part of the box cover is threadedly connected with a top support rod, the upper end of the top support rod is fixedly mounted with a handle, and the lower end of the top support rod extends through the inner part of the outer box body."

After the electrical instrument equipment is fixed, the protection box 1 is moved to a specified area indoors or outdoors for fixing. A triangular ceiling is fixedly provided on the top surface of the protection box 1, and the ceiling can provide simple shielding against rainwater.

[0028] Both sides of the protection box 1 are horizontally and equidistantly provided with a plurality of heat dissipation openings 2, and the plurality of heat dissipation openings 2 can dissipate heat and ventilate the heat generated by the operation of the electrical instrument equipment in the protection box 1, and the inner cavity of each heat dissipation opening 2 is provided with a baffle 3, and one side of each baffle 3 extends to the inner cavity of the protection box 1, and the other side of the baffle 3 extends to one side of the protection box 1, and each baffle 3 is connected to a side wall of the protection box 1 through a hinge 4, and each hinge 4 is arranged above the heat dissipation opening 2, and when dissipating heat on a rainy day , bend the baffle 3 and let it rotate clockwise with the hinge 4 as the axis, so that the baffle 3 can press against the top surface of the inner cavity of the heat dissipation port 2, and the heat can be dissipated from the space between the baffle 3 and the bottom surface of the inner cavity of the heat dissipation port 2. When it rains, rotate the baffle 3 in the opposite direction and let it rotate counterclockwise with the hinge 4 as the axis, so that the baffle 3 can press against the top surface and the bottom surface of the inner cavity of the heat dissipation port 2 in an inclined state, so that the baffle 3 can restrict the heat dissipation port 2 and reduce the situation where rainwater will enter from the heat dissipation port 2.

[0029] Two rotating rods 5 are rotatably connected to the top wall of the inner cavity of the protection box 1. The two rotating rods 5 are longitudinally arranged. The circumferential sides of the two rotating rods 5 are connected with movable cylinders 6 through threads. The top surface of each baffle 3 and the inner cavity of the protection box 1 are provided with circular grooves 7 for the movable cylinder 6 to pass through. The movable cylinder 6 and the multiple circular grooves 7 are in the same longitudinal horizontal plane. A plurality of pressure plates 8 are fixedly provided on the circumferential side of the movable cylinder 6. Every two pressure plates 8 are respectively arranged above and below the baffle 3. The diameter of each pressure plate 8 is larger than the diameter of the circular groove 7. By rotating the rotating rod 5, the rotating rod 5 drives the movable cylinder 6 to move longitudinally through the thread. Since each baffle 3 is arranged between two pressure plates 8, when the movable cylinder 6 moves downward, the pressure plate 8 located above the baffle 3 will press against The baffle plate 3 is pressed against and pushed by the baffle plate 3, so that the baffle plate 3 can rotate clockwise with the hinge 4 as the axis, so that the baffle plate 3 can press against the inner cavity top surface of the heat dissipation port 2, and the restriction on the heat dissipation port 2 is cancelled; when the movable cylinder 6 moves upward, the pressure plate 8 located below the baffle plate 3 will also press against and push the baffle plate 3, so that the baffle plate 3 can rotate counterclockwise with the hinge 4 as the axis, so that the baffle plate 3 can press against the inner cavity top surface and the inner cavity bottom surface of the heat dissipation port 2 in an inclined state, and restrict the heat dissipation port 2, which is convenient for protecting and dissipating rainwater, and also convenient for adjusting multiple baffle plates 3 synchronously, which can reduce the excessive heat inside the protection box 1 and the rainwater entering the protection box 1, and improve the service life of electrical instrument equipment.

[0031] A rotating shaft 12 is transversely provided in the upper half of the inner cavity of the protective box 1 and on one side of the two rotating rods 5.

Limit blocks 11 are fixedly provided on the side of the two movable cylinders 6 facing the vertical grooves 9. The two limit blocks 11 are slidably adapted with the two vertical rods 10 respectively. When the rotating rod 5 drives the movable cylinder 6 to move longitudinally through the thread, the movable cylinder 6 will drive the limit blocks 11 to move around the vertical rods 10, so that the vertical rods 10 and the limit blocks 11 restrict the movable cylinder 6 to prevent the movable cylinder 6 from rotating with the rotating rod 5.

[0033] Working principle:

[0034] The electrical instrument protection device fixes the electrical instrument in the protection box 1, and fixes the protection box 1 in a specified area. When the heat emitted by the electrical instrument equipment needs to be dissipated, the handle 15 is turned to drive the rotating shaft 12 to rotate, and then the rotating shaft 12 drives the rotating rod 5 to rotate through the mutually meshing conical teeth 13 and the transmission teeth 14, so as to drive the movable cylinder 6 to move downward. Since each baffle 3 is arranged between two pressure plates 8, when the movable cylinder 6 drives the pressure plate 8 to move downward, the pressure plate 8 located above each baffle 3 will press against each baffle 3 and push the baffle 3, so that the baffle 3 can be axially moved with the hinge 4 as the axis. The center of the handle 15 is rotated clockwise, so that the baffle 3 fits against the top wall of the inner cavity of the heat dissipation port 2, so that the restriction on the heat dissipation port 2 can be cancelled, and the heat in the protection box 1 can be dissipated and ventilated. On rainy days, the handle 15 is rotated in the opposite direction, so that the rotating rod 5 drives the movable cylinder 6 to move upward, so that the pressure plate 8 under each baffle 3 presses against each baffle 3, and the baffle 3 is rotated counterclockwise with the hinge 4 as the axis, so that each baffle 3 presses against the top and bottom surfaces of the heat dissipation port 2 in an inclined state, so that the heat dissipation port 2 can be restricted, the situation where rainwater will not enter the protection box 1 through the heat dissipation port 2 is reduced, and the service life of the electrical instrument is increased.
