Description

Technical Field

[0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. In the prior art, many electrical equipment are installed in electrical equipment boxes. This first allows for good management of the electrical equipment, and secondly, these devices are uniformly installed in electrical equipment boxes so that there is no need to drill holes in the wall for installation. These various benefits also bring a lot of inconvenience to people.

[0003] For example, a Chinese patent (publication number: CN 107069518 B) discloses a pull-out type electrical equipment box, including a box body, wherein a plurality of support plates for mounting electrical components are arranged inside the box body, two mounting blocks are arranged under each of the support plates, and the two mounting blocks are respectively mounted on opposite side surfaces inside the box body, and a slide groove is also provided on the opposite side surfaces between the two mounting blocks, and a movable plate is provided between the two slide grooves, and both ends of the movable plate slide along the surface of the slide groove, and a second fixed block is installed on the upper surface of the movable plate, and a first ball groove is provided on the upper surface of the second fixed block. The invention has a simple structure and is easy to use. It is not only convenient for the support plate to be pulled out in the horizontal direction, but also convenient for the support plate to be rotated in the horizontal direction, thereby improving the maintenance of electrical equipment by the staff.

[0004] The above-mentioned pull-out type electrical equipment box still has certain shortcomings. When pulling out the support plate, the movable plate is first pulled to make the movable plate slide in the slide groove of the mounting block, so that the electrical components on the support plate are moved out of the box, which is convenient for the staff to inspect and repair the electrical components. By manually pulling the support plate, the movable plate drives the installed electrical equipment to move together. Not only is the pulling process time-consuming and laborious, but the support plate needs to be rotated. Not only is the operation complicated, but the movable plate will fall when it moves a large distance, causing damage to the electrical equipment. Therefore, a pull-out type electrical equipment box is proposed to solve the above-mentioned problems. Utility Model Content

[0008] Furthermore, the transmission assembly includes a sprocket fixed to the outer surface of the threaded rod, and the outer surfaces of the two sprockets are transmission-connected with chains.

[0009] Furthermore, the first bevel gear is meshed with the second bevel gear, and two sliding holes are provided on the upper surface of the housing, and the connecting block is slidably connected to the inside of the sliding holes.

The outer surfaces of the two threaded rods 304 are provided with a transmission assembly 305. The left end threaded rod 304 drives the right end threaded rod 304 to rotate through the transmission assembly 305. The outer surfaces of the two threaded rods 304 are threadedly connected with a moving block 306, and two connecting blocks 307 are fixed to the upper surface of the moving block 306. The upper surfaces of the two connecting blocks 307 are fixed with a fixing plate 308. The electrical equipment is installed on the upper surface of the fixing plate 308, and a baffle 309 is fixed to the front of the fixing plate 308. The back of the baffle 309 abuts against the front of the box 1 to prevent dust from entering.

[0026] The transmission assembly 305 includes a sprocket fixed to the outer surface of the threaded rod 304 , and the outer surfaces of the two sprockets are transmission-connected with chains. The left-end threaded rod 304 drives the right-end threaded rod 304 to rotate through the transmission assembly 305 .

[0027] In addition, the first bevel gear 302 is meshed with the second bevel gear 303, and the motor 301 drives the first bevel gear 302 to rotate, driving the second bevel gear 303 and the left-end threaded rod 304 to rotate together. Two sliding holes are provided on the upper surface of the shell 2, and the connecting block 307 is slidably connected to the inside of the sliding hole, so that the movable block 306 drives the fixed plate 308 to move through the connecting block 307. Slide blocks are fixed on the left and right sides of the fixed plate 308, and multiple sliding grooves are provided on the left and right sides of the inner cavity of the box body 1. The sliders are slidably connected to the inside of the sliding grooves to increase the stability of the fixed plate 308 when moving.

[0028] In addition, a vertical plate is fixed between the left and right sides of the inner cavity of the shell 2, two sliding rods are fixed on the front of the vertical plate, and the moving block 306 is slidably connected to the outer surface of the sliding rod to increase the stability of the moving block 306 when moving. Two rotating holes are opened on the front of the vertical plate, and the threaded rod 304 is rotatably connected to the inside of the rotating hole through a bearing.

[0029] In the moving mechanism 3 of this embodiment, the motor 301 drives the first bevel gear 302 to rotate, and drives the second bevel gear 303 and the left-end threaded rod 304 to rotate together. The left-end threaded rod 304 drives the right-end threaded rod 304 to rotate through the transmission assembly 305. Through the rotation of the two threaded rods 304, the moving block 306, the connecting block 307, the fixed plate 308 and the baffle 309 are driven to move together, so that the fixed plate 308 is moved to the outside, which is convenient for maintenance of electrical equipment on the fixed plate 308.

[0030] See also Figure 4In order to dissipate heat for the electrical equipment, the heat dissipation mechanism 4 in this embodiment includes a plurality of through holes 401 opened on the left and right sides of the box body 1. The through holes 401 are evenly distributed to facilitate ventilation and heat dissipation. A dustproof net 402 is fixed inside the through holes 401 to prevent dust from entering the box body 1. The heat dissipation mechanism 4 also includes three fans 403 fixed to the left side of the inner cavity of the box body 1 and a temperature detector 404 fixed to the lower surface of the shell 2. The temperature of the electrical equipment is detected by the temperature detector 404, and the fan 403 is controlled to work according to the temperature.

[0031] Among them, the left side of the fan 403 corresponds to the right side of the left end through hole 401. The fan 403 draws external air through the left end through hole 401. Dust will be retained outside under the action of the dustproof net 402, and the air will pass through the fan 403 to dissipate heat and cool down the electrical equipment.

[0032] It should be noted that the electrical components appearing in the text are all electrically connected to the main controller and the power supply and the electrical components appearing in the text are all conventionally known devices, and this application will not go into too much detail. The main controller can be a conventionally known device that plays a control role such as a computer. The control circuit of the main controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and this application is mainly used to protect mechanical devices, so this application will no longer explain the control method and circuit connection in detail.

[0033] In the heat dissipation mechanism 4 of this embodiment, when the temperature detector 404 detects that the temperature of the electrical equipment has risen, the fan 403 draws in external air through the left end hole 401, and the dust will be retained outside under the action of the dustproof net 402. The air will pass through the fan 403 to dissipate heat and cool the electrical equipment, and the used air will be discharged through the right end hole 401 and the right end dustproof net 402.

[0034] The working principle of the above embodiment is:

[0035] (1) When it is necessary to pull out the fixed plate 308, start the motor 301, the motor 301 drives the first bevel gear 302 to rotate, and drives the second bevel gear 303 and the left-end threaded rod 304 to rotate together through the first bevel gear 302, and the left-end threaded rod 304 drives the left-end sprocket to rotate together, and the left-end sprocket drives the right-end sprocket and the right-end threaded rod 304 to rotate together through the chain, and the two threaded rods 304 rotate to drive the moving block 306 to move, and the moving block 306 will slide on the outer surface of the sliding rod to increase the stability of the moving block 306 when moving. When the moving block 306 moves, it will drive the fixed plate 308 and the baffle 309 to move together through the connecting block 307, so that the fixed plate 308 can be moved to the outside, and the electrical equipment on the fixed plate 308 can be maintained conveniently.

[0036] (2) When the temperature detector 404 detects that the temperature of the electrical equipment on the fixing plate 308 rises, the fan 403 is started, and the fan 403 draws in external air through the left end through hole 401. The dust in the air is retained outside by the left end dustproof net 402. The air passes through the fan 403 to dissipate heat and cool the electrical equipment. The air after use is discharged through the right end through hole 401 and the right end dustproof net 402.
