Detailed implementation manners

[0016] The following describes the principles and features of the present invention in conjunction with the drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0017] Please refer to Figures 1-7 , as shown in the figure, a power distribution cabinet that is convenient for maintenance provided in this embodiment, as Figure 1 shown, includes a power distribution cabinet 1, referring to Figures 6-7As shown in the figure, the power distribution cabinet 1 includes a cabinet body 101. An electrical connection line 102 is electrically connected to the bottom of the cabinet body 101. An installation bracket 103 is fixedly installed on one side of the cabinet body 101. Ventilation windows 104 are fixedly installed on both sides of the cabinet body 101. An inspection opening 105 is provided on one side of the cabinet body 101. An external shielding cover 2 is fixedly installed on one side of the cabinet body 101. The external shielding cover 2 is arranged on the outer periphery of the inspection opening 105 and is used for performing a preliminary shielding treatment on the inspection opening 105.

[0018] Combined with Figure 2 As shown in the figure, a protection mechanism 3 is provided on one side of the power distribution cabinet 1; Referring to Figures 6-7 As shown in the figure, the protection mechanism 3 includes a first supporting cover cylinder 31 fixedly installed on one side of the cabinet body 101. The first supporting cover cylinder 31 covers the outer periphery of the inspection opening 105. Combined with Figures 2-4 As shown in the figure, a positioning tray 32 is fixedly installed on the side of the first supporting cover cylinder 31 away from the cabinet body 101. A first guiding chute 33 is opened on one side of the positioning tray 32. A plurality of guiding slide rods 34 are slidably installed in the inner cavity of the first guiding chute 33. And a plurality of blocking pieces 35 are fixedly installed on the outer walls of the plurality of guiding slide rods 34. When in a normal state, the plurality of blocking pieces 35 are spliced together to cover one side of the positioning tray 32. Among them, a through hole is opened at the central part of the positioning tray 32. The inner circumferential diameter length of the through hole is greater than the outer circumferential diameter length of the inspection opening 105. A rotating assembly is provided on the outer walls of the plurality of guiding slide rods 34 for driving them to slide to open the through hole. The purpose of such a setting is that when the rotating assembly is started to drive the plurality of guiding slide rods 34 to drive the blocking pieces 35 to displace, gaps can be formed between the plurality of blocking pieces 35, so as to open the through hole at the central part of the positioning tray 32, so that the user can insert the inspection connection line through the through hole in the middle of the positioning tray 32 into the inspection opening 105.

[0019] It can be understood that during actual use, when the plug end of the inspection connection line needs to be inserted into the inspection opening 105, the plurality of blocking pieces 35 can be synchronously driven to slide along the inner track of the first guiding chute 33 in combination with the guiding slide rods 34, so that gaps are formed between the plurality of blocking pieces 35, thereby opening the through hole at the central part of the positioning tray 32, and the plug end of the inspection connection line can be inserted into the inspection opening 105. When the plug end of the inspection connection line is pulled out after the inspection is completed, by making the plurality of blocking pieces 35 slide in the reverse direction until the plurality of blocking pieces 35 are spliced together into a disc shape to cover the central part of the positioning tray 32, the communication between the inspection opening 105 and the outside can be blocked and covered, so as to prevent external rainwater or dust from entering the inspection opening 105.

[0020] Furthermore, among them, referring to Figure 3As shown, a plurality of guiding slide bars 34 and retaining plates 35 are arranged in an annular and equidistant manner around the inner circumferential surface of the positioning tray 32. Magnetic pads are fixedly installed on both sides of the plurality of retaining plates 35. The purpose of such a setting is that when the plurality of retaining plates 35 approach and are spliced together, a sealed connection state is maintained between the plurality of retaining plates 35. Thus, when there is rain washing outside, rainwater and dust will not penetrate into the inside of the inspection opening 105 from the gaps between the plurality of retaining plates 35, and the through hole can be stably kept closed for a long time.

[0021] Further, referring to Figures 3-4 As shown, the rotating assembly includes a hollow rotary disk 36 rotatably installed on the outer wall of the positioning tray 32. A plurality of second guiding chutes 37 slidably connected to the guiding slide bars 34 are formed inside the hollow rotary disk 36. In the normal state, the guiding slide bars 34 move inside the second guiding chutes 37 on the side closer to the center of the hollow rotary disk 36. At this time, the plurality of retaining plates 35 approach and are spliced together. When the hollow rotary disk 36 is rotated, and the plurality of guiding slide bars 34 move synchronously away from the center of the hollow rotary disk 36 inside the inner cavity of the second guiding chutes 37, the plurality of retaining plates 35 can be made to slide synchronously to expose a gap until the central part of the positioning tray 32 is opened.

[0022] Further, two positioning brackets 38 are fixedly installed on the outer wall of the hollow rotary disk 36. First magnetic attraction blocks 39 are fixedly installed on one side of the two positioning brackets 38. Combining Figure 5 As shown, two arc-shaped support blocks 310 are fixedly installed on one side of the cabinet body 101, and second magnetic attraction blocks 311 magnetically attracted to the first magnetic attraction blocks 39 are fixedly installed on one side of the two arc-shaped support blocks 310. Referring to Figures 3-4 As shown, the arc-shaped support blocks 310 and the center of the hollow rotary disk 36 are arranged at the same position, and the radius length of the arc-shaped support blocks 310 from the center is the sum of the radius length of the hollow rotary disk 36 and the height of the upper positioning bracket 38. The purpose of such a setting is that when actually adjusting the rotation of the hollow rotary disk 36, the first magnetic attraction blocks 39 can match the arc-shaped support blocks 310 and the second magnetic attraction blocks 311. Thus, when the rotation adjustment is completed and a gap is formed between the plurality of retaining plates 35 to open the central part of the positioning tray 32, the first magnetic attraction blocks 39 just adsorb to the second magnetic attraction blocks 311 on the arc-shaped support blocks 310, thereby fixing the deflection position of the hollow rotary disk 36, and further keeping the through hole in the center of the positioning tray 32 in an open state.

[0023] It can be understood that when the plug end of the maintenance connection line needs to be inserted deeply into the maintenance port 105 during the maintenance operation of the power distribution cabinet, the maintenance personnel can first rotate the hollow turntable 36 towards the direction close to the second magnetic attraction block 311, so that the plurality of guiding slide rods 34 slide in the inner cavity of the second guiding chute 37. Subsequently, the plurality of blocking pieces 35 are released from the magnetic attraction and closed state, and are displaced synchronously to gradually open the through hole in the middle of the positioning tray 32 until the first magnetic attraction block 39 is adsorbed and fixed to the second magnetic attraction block 311, and the through hole in the middle of the positioning tray 32 is completely opened. Then, the plug end of the maintenance connection line can be inserted deeply into the maintenance port 105. When the maintenance is completed, after the maintenance connection line is pulled out, the hollow turntable 36 can be rotated in the reverse direction, so that the plurality of guiding slide rods 34 drive the blocking pieces 35 to approach each other and displace until the plurality of blocking pieces 35 are adsorbed to each other and spliced into a disc shape to cover the through hole in the middle of the positioning tray 32, and then the maintenance port 105 can be closed and blocked to prevent rainwater and dust from entering the interior of the maintenance port 105.

[0024] Optionally, a plurality of through ventilation grooves 312 are formed in the outer wall of the first supporting cover cylinder 31, and the outer circumferential diameter length of the positioning tray 32 is greater than the outer circumferential diameter length of the first supporting cover cylinder 31; a plurality of water absorption pads 313 are fixedly installed on one side of the hollow turntable 36, and cleaning brushes 314 are fixedly installed on the water absorption pads 313.

[0025] Specifically, as a further expansion of this solution, in combination with Figure 7 As shown, a plurality of through ventilation grooves 312 are formed in the outer wall of the first supporting cover cylinder 31, and the outer circumferential diameter length of the positioning tray 32 is greater than the outer circumferential diameter length of the first supporting cover cylinder 31. After the side of the maintenance port 105 facing the user is sealed and covered by the plurality of spliced blocking pieces 35, the inner cavity of the first supporting cover cylinder 31 can still maintain a ventilation state. And when ventilating, due to the auxiliary shielding of the positioning tray 32, rainwater from the outside will not enter the inner cavity of the first supporting cover cylinder 31 through the ventilation grooves 312. And, in combination with Figure 4 As shown, a plurality of water absorption pads 313 are fixedly installed on the side of the hollow turntable 36 close to the cabinet body 101, and cleaning brushes 314 are fixedly installed on the inner walls of the plurality of water absorption pads 313.

[0026] It can be understood that during actual use, when the hollow turntable 36 is rotated to move and adjust multiple baffles 35, multiple water absorption pads 313 and cleaning brushes 314 rotate synchronously around the outer wall of the first supporting cover cylinder 31, so that the cleaning brushes 314 move on the outer surface of the first supporting cover cylinder 31 to sweep away dust and impurities on the ventilation grooves 312, avoiding the problem that dust blocks the ventilation grooves 312 and affects the air circulation inside the first supporting cover cylinder 31. At the same time, the multiple water absorption pads 313 and cleaning brushes 314 are arranged in an annular and equally spaced state in sequence around the outer circumferential surface of the first supporting cover cylinder 31.

[0027] Further preferably, a self-cleaning mechanism 4 is further provided inside the protection mechanism 3. The self-cleaning mechanism 4 includes a second supporting cover cylinder 41. A plurality of air storage cylinders 42 are fixedly installed inside the second supporting cover cylinder 41. A magnetic push rod 43 is inserted into the air storage cylinder 42. One end of the magnetic push rod 43 extending into the air storage cylinder 42 is fixedly installed with a telescopic spring 44, and a mutually repulsive magnetic pole block is fixedly installed at the end of the magnetic push rod 43 opposite to the guiding slide rod 34. When the through hole of the positioning tray 32 is opened, the hollow turntable 36 rotates to drive the guiding slide rod 34 to approach the magnetic push rod 43. A plurality of air diffusing pipes 45 communicated with the air storage cylinders 42 are fixedly installed on the inner wall of the second supporting cover cylinder 41. A plurality of through exhaust holes 46 are formed in the air diffusing pipes 45.

[0028] Specifically, as a further expansion of this solution, in combination with Figures 5-7As shown, a self-cleaning mechanism 4 is provided inside the protection mechanism 3. The self-cleaning mechanism 4 includes a second support cylinder 41 disposed between the first support cylinder 31 and the inspection opening 105 and fixedly connected to the cabinet body 101. A plurality of air storage cylinders 42 are fixedly installed inside the second support cylinder 41. Magnetic push rods 43 are inserted into the interiors of the plurality of air storage cylinders 42, and telescopic springs 44 fixedly connected to the air storage cylinders 42 are fixedly installed at one ends of the plurality of magnetic push rods 43 extending into the interiors of the air storage cylinders 42. In the normal state, the plurality of telescopic springs 44 are in an extended state to push the magnetic push rods 43 out of the inner cavities of the air storage cylinders 42; a mutually repulsive magnetic pole block is fixedly installed at one end of the magnetic push rod 43 opposite to the guiding slide rod 34. The magnetic push rod 43 and the guiding slide rod 34 can cooperate with each other. When the through hole of the positioning tray 32 is opened and the hollow turntable 36 rotates, the guiding slide rod 34 can be driven to approach the position where the magnetic push rod 43 is located. Under the action of the mutually repulsive magnetic force, the magnetic push rod 43 will be pressed downward in the inner cavity of the air storage cylinder 42; on the contrary, when the hollow turntable 36 rotates in the reverse direction, the magnetic push rod 43 will be reset under the action of the telescopic spring 44. At the same time, a plurality of air dispersion pipes 45 communicating with the air storage cylinders 42 are fixedly installed on the inner wall of the second support cylinder 41. A plurality of exhaust holes 46 penetrating through are formed on the outer walls of the plurality of air dispersion pipes 45. Among them, the plurality of air dispersion pipes 45 are arranged in an annular and equidistant state in sequence around the inner circumferential surface of the second support cylinder 41. Preferably, the magnetic force between the first magnetic attraction block 39 and the second magnetic attraction block 311 can be greater than the mutually repulsive force on the same plane between the guiding slide rod 34 and the magnetic push rod 43 to prevent the first magnetic attraction block 39 and the second magnetic attraction block 311 from being bounced off after being magnetically attracted and connected.

[0029] It can be understood that during actual use, when the plug end of the maintenance connection line needs to be inserted deep into the maintenance port 105 during the maintenance operation of the power distribution cabinet, the maintenance personnel can first rotate the hollow turntable 36 in the direction close to the second magnetic attraction block 311, so that the plurality of guiding sliding rods 34 slide in the inner cavity of the second guiding chute 37. At this time, while opening the middle through hole of the positioning tray 32, the guiding sliding rods 34 will move towards the position where the magnetic push rod 43 is located. Since mutually exclusive magnetic pole blocks are provided at the opposite ends of the guiding sliding rod 34 and the magnetic push rod 43, a gradually increasing repulsive force is generated between the guiding sliding rod 34 and the magnetic push rod 43. This repulsive force can push the magnetic push rod 43 into the interior of the air storage cylinder 42, and then the gas is blown out at the exhaust hole 46 through the air diffusing pipe 45. When the first magnetic attraction block 39 and the second magnetic attraction block 311 are adsorbed and fixed together, the repulsive force between the guiding sliding rod 34 and the magnetic push rod 43 reaches the maximum, and the gas in the air storage cylinder 42 is blown out to the greatest extent, so as to remove the dust on the metal connectors or metal contacts in the maintenance port 5, further avoiding the problem of signal quality deterioration caused by poor contact due to dust accumulation, which affects the maintenance efficiency; on the contrary, when the hollow turntable 36 is rotated in the reverse direction, the guiding sliding rod 34 and the magnetic push rod 43 move away from each other and the repulsive force decreases, and the telescopic spring 44 will push the magnetic push rod 43 out for reset; at the same time, when the maintenance personnel think that there is still dust on the metal connectors or metal contacts that affects the maintenance, the hollow turntable 36 can be rotated repeatedly to make the exhaust hole 46 blow air repeatedly, so as to avoid the situation that the metal connectors or metal contacts are damaged due to the need for additional cleaning operations by the maintenance personnel; the above settings enable the present invention to automatically clean the metal connectors or metal contacts while opening the through hole of the positioning tray 32, further effectively avoiding the maintenance problems caused by dust, and greatly improving the maintenance efficiency.

[0030] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
