Detailed description of the specific implementation mode

[0025] The following will describe the specific implementation mode of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific implementation mode described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0026] In the present disclosure, unless otherwise stated, the orientation terms such as "upper, lower, left, right" are defined according to the direction of the mobile power distribution cabinet, and specifically can be referred to Figure 2In the drawing direction, "inside" and "outside" are defined according to the outline of the corresponding parts. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0027] See also Figure 1 , a mobile power distribution cabinet is provided in an embodiment of the present disclosure, and the mobile power distribution cabinet may include a cabinet 100, an exhaust mechanism 200 and an air filtering mechanism 300. Among them, the cabinet 100 may be provided with an air inlet 110 and an air outlet 120, and a grille may be installed at the air outlet 120. The cabinet 100 may be provided with an observation window to facilitate users to view internal electrical components. The exhaust mechanism 200 may be installed at the air inlet 110 to suck cold air from the outside of the cabinet 100 into the inside of the cabinet 100 at the air inlet 110. The exhaust mechanism 200 may include a fan 210 capable of exhausting air and a mounting rod 220, the two ends of the mounting rod 220 are respectively fixed on two opposite walls of the air inlet 110, and the fan 210 may be installed on the mounting rod 220. The air filtering mechanism 300 may include a filter element 320 and an installation assembly 310 for installing the filter element 320. The installation assembly 310 may be movably connected to the cabinet 100 to facilitate the disassembly and replacement of the air filtering mechanism 300. The filter element 320 may be disposed at the air inlet 110 to filter the cold air entering the air inlet 110. The filter element 320 may be a filter cloth or a metal mesh covered with dense small holes.

[0028] It is understandable that the exhaust mechanism 200 is installed at the air inlet 110 of the cabinet 100, and the filter 320 is installed at the air inlet 110 through the mounting assembly 310. The exhaust mechanism 200 filters the cold air outside the cabinet 100 at the air inlet 110 through the filter 320 and then sucks it into the cabinet 100. The cold air can cool down the electrical components in the cabinet 100. The arrival of the external cold air can "squeeze" part of the original hot air in the cabinet 100 out of the cabinet 100 through the air outlet 120. By setting the filter 320, it is possible to prevent external dust from entering the cabinet 100 with the cold air, and to prevent dust from accumulating inside the cabinet 100, thereby ensuring the stability of the electrical components and improving the service life of the mobile power distribution cabinet. In addition, the mounting assembly 310 is movably connected to the cabinet 100, which improves the replacement efficiency of the air filter mechanism 300.

[0029] In one embodiment, see Figure 1 and Figure 3, the installation component 310 may include a frame body 311 and a door body 312. Among them, the frame body 311 may be hinged to the cabinet body 100. Specifically, the frame body 311 may be configured to be shape-adapted to the air inlet 110, and one side of the frame body 311 may be hinged to the cabinet body 100 on one side of the air inlet 110. The filter element 320 may be detachably connected to the frame body 311, facilitating the disassembly and replacement of the filter element 320. The door body 312 is provided with opposite first end 3121 and second end 3122. The first end 3121 of the door body 312 may be hinged to one side of the frame body 311, and the second end 3122 can be detachably connected to the opposite side of the frame body 311 through a bolt 313. The door body 312 can be used to limit the filter element 320 on the inner side close to the cabinet body 100 after the filter element 320 covers the air inlet 110, preventing the filter element 320 from falling out of the frame body 311 during use and hitting the electrical components inside the cabinet body 100, ensuring the stability and reliability of the operation of the electrical components. A handle may be installed on the door body 312 to facilitate the user to rotate the door body 312.

[0030] In this embodiment, the air filtering mechanism 300 may be located above the air extraction mechanism 200, preventing external dust from adhering to the fan blades during the rotation of the fan 210 and affecting the use effect of the fan 210. By providing the door body 312, it can prevent the filter element 320 from falling out of the frame body 311 during use and hitting the fan 210 below.

[0031] In this embodiment, please refer to Figure 3 and Figure 4 , the bolt 313 may include a bolt rod 3131 and an elastic member 3132. The elastic member 3132 may be sleeved on the bolt rod 3131 and may be elastically connected between the convex portion of the bolt rod 3131 and the door body 312. The elastic member 3132 can provide an elastic force for the bolt rod 3131, so that one end of the bolt rod 3131 away from the elastic member 3132 cannot extend out of the through hole of the door body 312 without being subjected to the pulling force of the user, preventing the door body 312 from being "accidentally opened". When the filter element 320 needs to be replaced, by pulling the bolt rod 3131 to make one end of the bolt rod 3131 extend out, the door body 312 can be opened.

[0032] In this embodiment, please refer to Figure 3 and Figure 5, the installation component 310 may further include a rubber frame 314. The rubber frame 314 can be circumferentially connected to the filter element 320. The filter element 320 can be connected to the frame body 311 through the rubber frame 314. First, it ensures that there is no gap between the four sides of the filter element 320 and the frame body 311, so as to ensure that external dust cannot enter the cabinet body 100 through the gap. Second, it can increase the friction between the filter element 320 and the frame body 311, and the two remain relatively stationary through the friction. Pulling the rubber frame 314 enables the rubber frame 314 to drive the filter element 320 to move relative to the frame body 311, so that the two can be movably connected, facilitating the removal and replacement of the filter element 320.

[0033] Further, the rubber frame 314 can be provided with a notch. A finger is inserted into the notch and the rubber frame 314 is pulled to remove the rubber frame 314 and the filter element 320 in the frame body 311.

[0034] In one embodiment, please refer to Figure 1 and Figure 2 , a plurality of bases 140 can be provided at the bottom of the cabinet body 100. Wheels 710 are installed on the bases 140. The mobile power distribution cabinet may further include a shock absorption mechanism 400. The number of the shock absorption mechanisms 400 can be multiple, and can be correspondingly arranged with the plurality of bases 140 one by one. The shock absorption mechanism 400 can be disposed between the base 140 and the cabinet body 100 to prevent the mobile power distribution cabinet from vibrating up and down when pushed or pulled to a bumpy road surface, thereby preventing the electrical components in the cabinet body 100 from vibrating up and down and ensuring the integrity of the electrical components.

[0035] Further, please refer to Figure 2 , the shock absorption mechanism 400 can include hydraulic dampers (not shown in the figure) and springs 410. The number of the hydraulic dampers and the springs 410 can both be multiple, and can be spaced apart and disposed on the base 140. For example, four hydraulic dampers and four springs 410 can be installed on each base 140. The springs 410 can buffer the vibration of the cabinet body 100. The main function of the hydraulic damper is to consume the vibration energy of the cabinet body 100 by providing resistance to motion, thereby reducing the vibration amplitude and vibration time of the cabinet body 100, achieving the purpose of shock absorption, and preventing the electrical components in the cabinet body 100 from vibrating up and down.

[0036] In this embodiment, the mobile power distribution cabinet may further include a limiting rod 510. One end of the limiting rod 510 may be installed on the cabinet body 100, and the other end may be slidably inserted through a through hole of the base 140. The end of the limiting rod 510 inserted through the through hole may have a protrusion, and the protrusion may be used to be restricted on one side of the bottom of the base 140. During the up-and-down vibration of the cabinet body 100, the limiting rod 510 may be driven to move, thereby driving the protrusion to approach or move away from (approach when the cabinet body 100 moves upward and move away when the cabinet body 100 moves downward) the bottom of the base 140. When the protrusion abuts against the bottom of the base 140, the upward movement of the cabinet body 100 may be restricted, avoiding excessive stretching of the spring 410.

[0037] In this embodiment, please refer to Figure 2 , the spring 410 may be sleeved on the outer periphery of the limiting rod 510. The installation of the limiting rod 510 makes full use of the middle space of the spring 410, saving the space occupied by the limiting rod 510. Moreover, the limiting rod 510 may play a guiding role for the spring 410 to limit the telescopic direction of the spring 410.

[0038] In one embodiment, please refer to Figure 1 and Figure 2 , the mobile power distribution cabinet may further include a supporting mechanism 600. The supporting mechanism 600 may be arranged on the cabinet body 100 for supporting the cabinet body 100. The supporting mechanism 600 may be configured to be able to move along the gravity direction of the cabinet body 100. When the mobile power distribution cabinet moves to the working position, the supporting mechanism 600 moves downward until it abuts against the ground, increasing the contact area between the mobile power distribution cabinet and the ground, avoiding the cabinet body 100 sliding relative to the ground during the operation of the electrical components, and ensuring the stability and reliability of the operation of the electrical components.

[0039] In one embodiment, please refer to Figure 1 , the number of the supporting mechanisms 600 is four, and they are oppositely installed on both sides of the cabinet body 100, so that both sides of the cabinet body 100 can be in stable contact with the road surface, ensuring that the cabinet body 100 cannot slide relative to the road surface.

[0040] In one embodiment, please refer to Figure 2, the support mechanism 600 may include a driving motor 610, a lead screw 620, a guide rod 630, a movable block 640, and a support plate 660. The driving motor 610 may be installed on the cabinet 100 and may be in transmission connection with the lead screw 620. The driving motor 610 may be a stepper motor. The lead screw 620 may pass through the movable block 640 and may be screwed to the movable block 640. The guide rod 630 may be installed on the cabinet 100 and may slidably pass through the movable block 640 through a sliding sleeve 680, for restricting the movable block 640 from rotating during movement, ensuring that the movable block 640 cannot "accidentally touch" the surrounding structures during the lifting process. Among them, the movable block 640 is installed on the support plate 660, and the support plate 660 is used to support the cabinet 100 when contacting the ground. Specifically, when the cabinet 100 drives the electrical components to move to the working positions of the electrical components, the driving motor 610 drives the lead screw 620 to rotate, so that the movable block 640 can move downward until the support plate 660 abuts against the road surface, increasing the contact area between the cabinet 100 and the road surface, preventing the cabinet 100 from sliding relative to the road surface, ensuring that the wires between the electrical components and the equipment will not be pulled, and thus ensuring that the electrical components can provide stable power support for the equipment through the wires.

[0041] In one embodiment, please refer to Figure 2 , the support mechanism 600 may further include a connecting frame 670 and a support column 650. Among them, the connecting frame 670 may be installed on the cabinet 100, the driving motor 610 may be installed on the connecting frame 670, and the end of the lead screw 620 away from the driving motor 610 may be rotatably arranged on the connecting frame 670. For example, the end of the lead screw 620 can rotatably extend into the circular groove formed in the connecting frame 670. Both ends of the guide rod 630 may be connected to the connecting frame 670 respectively, ensuring that both ends of the guide rod 630 are in a fixed state, ensuring that the guide rod 630 can provide stable guidance for the movable block 640. However, because the lower end of the guide rod 630 is connected to the bottom of the connecting frame 670, the movable block 640 cannot cross the bottom of the connecting frame 670 and abut against the road surface. By arranging the support plate 660 at the bottom end of the support column 650, the support column 650 can be arranged between the movable block 640 and the support plate 660, avoiding the installation position of the connecting frame 670, so that the movable block 640 can abut against the road surface through the support plate 660, preventing the cabinet 100 from sliding relative to the road surface.

[0042] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0043] In addition, it should be noted that, for the various specific technical features described in the above specific embodiments, they can be combined in any appropriate manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0044] In addition, any combination can be made among the various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
