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

[0017] Please refer to Figures 1-7As shown in the figure, this embodiment provides a power cabinet that is easy to maintain, such as Figures 1-2 As shown, it comprises an inverted L-shaped shielding frame 1, a lifting mechanism 2 is installed on one side of the inverted L-shaped shielding frame 1, and a power cabinet body is installed in the lifting mechanism 2.

[0018] Reference Figures 2-3 As shown, the lifting mechanism 2 includes a cabinet mounting frame 24 slidably connected to one side of the inverted L-shaped protective frame 1, a lifting adjustment seat 23 is fixedly connected to one side of the cabinet mounting frame 24, and rotating lifting rods 22 are threadedly connected to both sides of the lifting adjustment seat 23. A positioning support beam 21 is fixedly connected below the protruding portion of the inverted L-shaped protective frame 1, and the top of the rotating lifting rod 22 is rotatably connected to the positioning support beam 21.

[0019] Specifically, the inverted L-shaped protective frame 1 can be divided into a top protrusion and a vertical portion according to its shape. The protrusion can provide certain shielding and protection for the main body of the power cabinet to prevent rain and snow from falling directly on the main body of the power cabinet. At the same time, the main body of the power cabinet is installed inside the cabinet mounting frame 24. In addition, the two rotating lifting rods 22 are arranged in a vertical state.

[0020] When the rotary lifting rod 22 rotates, it can drive the cabinet installation frame 24 and the power cabinet body to rise or fall.

[0021] Specifically, by rotating the two rotating lifting rods 22, the lifting and adjusting seat 23 can drive the cabinet installation frame 24 to move up and down on its outer wall as a whole. Therefore, according to the actual use status, when the power cabinet needs to be maintained, the lifting and adjusting seat 23 can be driven to rotate to drive the rotating lifting rods 22 to drive the overall height of the cabinet installation frame 24 to decrease. There is no need for workers to climb up to repair or disassemble the power cabinet for repair, which is more convenient to use. After the maintenance is completed, the cabinet installation frame and the main body of the power cabinet can be lifted to a high place as a whole to avoid electric shock injuries.

[0022] Among them, one end of the rotating lifting rod 22 extending from the top surface of the positioning support beam 21 is fixedly connected to a transmission wheel 25, and the two transmission wheels 25 are connected by a synchronous rotating belt 26, and one of the transmission wheels 25 is fixedly connected to a power motor.

[0023] When the power motor is started, it can drive the two rotating lifting rods 22 to rotate.

[0024] Specifically, during use, the staff can start the power motor, causing the corresponding drive wheel disc 25 to start rotating, thereby driving the rotary lifting rod 22 to rotate. Through the settings of the drive wheel disc 25 and the synchronous rotating belt 26, the two rotary lifting rods 22 will rotate synchronously, and then drive the lifting adjustment seat 23 to move smoothly up and down on the two rotary lifting rods 22.

[0025] Furthermore, the rotary lifting rod 22 also penetrates through the upper and lower end faces of the cabinet installation frame 24 and is slidably connected to the cabinet installation frame 24. The lifting adjustment seat 23 is arranged at the horizontal center line position of the cabinet installation frame 24. Specifically, the above settings enable the overall force on the cabinet installation frame 24 to be more uniform, so that it can stably bear the weight of the power cabinet and will not affect the stable up and down reciprocating movement and adjustment work of the lifting adjustment seat 23.

[0026] It should be noted that the power cabinet main body may shake during the lifting process, which may affect the operating stability of the electronic components inside the power cabinet main body. In severe cases, it may even cause the power cabinet main body to overturn and be damaged. Therefore, a vertical fixing mechanism 4 can be specifically designed as follows:

[0027] It also includes a vertical fixing mechanism 4. Refer to Figures 2-5 As shown, the vertical fixing mechanism 4 includes a plurality of support connecting rods 41 fixedly connected inside the cabinet installation frame 24. A sliding connecting plate 42 is slidably sleeved on the support connecting rods 41. A limiting control plate 43 is fixedly connected between the sliding connecting plates 42. A hollow connecting column 44 is fixedly connected below the limiting control plate 43. The lower part of the hollow connecting column 44 is elastically connected with a pressing locking disc 45 through a second spring member 46.

[0028] Specifically, the bottom of the hollow connecting column 44 is arranged in an open shape. One end of the pressing locking disc 45 extending into the inner cavity of the hollow connecting column 44 is fixedly installed with a second spring member 46 fixedly connected to the limiting control plate 43. The second spring member 46 is in an extended state under normal conditions.

[0029] A deflecting pressure rod 47 is hinged to the upper end face of the limiting control plate 43. An electric rotating disc 48 is fixedly connected to the middle of the cabinet installation frame 24. The tops of the deflecting pressure rods 47 are all hinged to the bottom surface of the electric rotating disc 48.

[0030] In the initial state, the deflecting pressure rod 47 is in an inclined state. When the electric rotating disc 48 rotates, it can push the limiting control plate 43 to press downwards.

[0031] Specifically, the deflecting pressure rod 47 is in an inclined state under normal conditions. At this time, the distance between the limiting control plate 43 and the electric rotating disc 48 is relatively close.

[0032] It can be understood that when vertical fixed limit is required for the main body of the power cabinet, the electric rotary disk 48 can be started to rotate, thereby driving the deflector pressure rod 47 in an inclined state hinged below it to deflect synchronously, and then the deflector pressure rod 47 gradually changes from an inclined state to a vertical state. During this process, the distance between the limit control plate 43 and the electric rotary disk 48 gradually increases, that is, the deflector pressure rod 47 will continuously press down on the limit control plate 43, thereby achieving the purpose of continuously pressing down the limit control plate 43;

[0033] At the same time, during the continuous downward pressing of the limit control plate 43, it will synchronously drive the hollow connecting column 44 and the pressing and locking disk 45 to move downward. When the pressing and locking disk 45 contacts the top of the power cabinet, it will cause the pressing and locking disk 45 to gradually squeeze the second spring member 46 into the inner cavity of the hollow connecting column 44 until the pressing and locking disk 45 fits with the bottom of the hollow connecting column 44. At this time, the upper and lower end faces of the pressing and locking disk 45 are respectively in mutual contact and pressing with the bottom of the hollow connecting column 44 and the top of the main body of the power cabinet. After an extrusion force is formed among the limit control plate 43, the hollow connecting column 44, the pressing and locking disk 45 and the main body of the power cabinet, the top of the main body of the power cabinet can be limited and fixed, enhancing the installation stability of the main body of the power cabinet in the vertical direction. Of course, similarly, the user can also control the electric rotary disk 48 to reverse, so that the limit control plate 43 gradually moves towards the position where the electric rotary disk 48 is located, thereby releasing the vertical fixed limit on the top of the main body of the power cabinet.

[0034] Furthermore, the number of the deflector pressure rods 47 is set to be multiple, and the multiple deflector pressure rods 47 are arranged in a circular shape at equal intervals in sequence.

[0035] Specifically, the purpose of such a setting is that when the electric rotary disk 48 is rotated to change the inclination of the multiple deflector pressure rods 47, a pressing and pulling force can be stably and evenly generated on the top of the limit control plate 43, so that the force on the limit control plate 43 and the multiple sliding connecting plates 42 is more uniform, and then it can slide stably on the outer wall of the supporting connecting rod 41.

[0036] It should be noted that although the above-mentioned embodiment realizes the vertical fixed limit of the main body of the power cabinet, during the installation process of the main body of the power cabinet, there is still a situation where the installation position of the main body of the power cabinet is not centered and the overall center of gravity of the structure shifts, resulting in possible lateral vibration or deviation of the main body of the power cabinet during the upward movement. Therefore, a lateral auxiliary mechanism 3 can be specifically designed, as detailed below:

[0037] Further preferably, a lateral auxiliary mechanism 3 is also included, in combination with Figures 5-7As shown in the figure, the lateral auxiliary mechanism 3 includes positioning bases 31 installed on both sides of the cabinet installation frame 24. One side of each positioning base 31 is fixedly connected with a shock-absorbing sleeve 32. Specifically, shock-absorbing sleeves 32 are fixedly connected to the opposite inner sides of the positioning bases 31, and the shock-absorbing sleeves 32 are arranged perpendicular to the positioning bases 31.

[0038] A support bracket 33 elastically connected by a first spring member 34 is provided in the shock-absorbing sleeve 32. A lateral adjustment rod 38 is fixedly connected to the other side of each positioning base 31. The other end of each lateral adjustment rod 38 is fixedly connected with a connecting support plate 39. A supporting sliding frame 310 is fixedly connected to the middle of the hollow connecting column 44. A synchronous gear disk 312 is rotatably connected to the bottom of the hollow connecting column 44. Displacement adjustment racks 311 are slidably connected to the sliding grooves on both sides of the supporting sliding frame 310. The displacement adjustment racks 311 are engaged with the synchronous gear disk 312, and one end of each displacement adjustment rack 311 is fixedly connected to one of the two connecting support plates 39.

[0039] Specifically, the synchronous gear disk 312 is located between the pressing and locking disk 45 and the hollow connecting column 44. The pressing and locking disk 45 penetrates through the synchronous gear disk 312 and can still elastically slide within the hollow connecting column 44. The two displacement adjustment racks 311 are arranged parallel to each other. The two connecting support plates 39 are arranged parallel to each other, and the corresponding displacement adjustment rack 311 and connecting support plate 39 are arranged perpendicular to each other.

[0040] When the synchronous gear disk 312 rotates, it can drive the two support brackets 33 to approach or move away from each other synchronously.

[0041] Specifically, when pushed by an external force, the synchronous gear disk 312 can be driven to rotate, and the two displacement adjustment racks 311 and their corresponding lateral adjustment rods 38 drive the positioning bases 31 to move synchronously in the opposite direction. In the normal state, the two positioning bases 31 approach each other, and the connecting support plates 39 also move to fit against the outer wall of the synchronous gear disk 312.

[0042] Furthermore, the two displacement adjustment racks 311 are symmetrically arranged with respect to the horizontal center line of the hollow connecting column 44, and the two connecting support plates 39 are symmetrically arranged with respect to the vertical center line of the hollow connecting column 44. Specifically, the purpose of such an arrangement is to enable the two displacement adjustment racks 311 to move synchronously.

[0043] It can be understood that when it is necessary to limit and fix the main body of the power cabinet, the staff can place the main body of the power cabinet on the cabinet installation frame 24 and place it between the two positioning bases 31. According to the different width dimensions of the power cabinet, the staff can move the horizontal adjustment rod 38. At this time, the horizontal adjustment rod 38 will drive the connecting support plate 39, so that the displacement adjustment rack 311 can easily move on the outer wall of the synchronous gear disk 312, so that the two positioning bases 31 move synchronously until the support brackets 33 on both sides are attached to both sides of the main body of the power cabinet, that is, the main body of the power cabinet is exactly centered between the two positioning bases 31, realizing the centered installation of the main body of the power cabinet and ensuring the stability of the overall structure center of gravity; After that, the staff can start the electric rotating disk 48 to make it rotate, and the deflecting pressure rod 47 will gradually change to the vertical state, and at the same time generate a downward thrust on the hollow connecting column 44 and the pressing locking disk 45. When the lower end surface of the pressing locking disk 45 contacts the top of the main body of the power cabinet, the hollow connecting column 44 is still descending until the upper end surface of the pressing locking disk 45 generates a mutual pressing force with the lower end surface of the synchronous gear disk 312, and then a huge frictional force is generated between the pressing locking disk 45 and the synchronous gear disk 312. At this time, the pressing locking disk 45 can not only vertically fix and limit the main body of the power cabinet on the top of the main body of the power cabinet, but also lock the synchronous gear disk 312, and then limit the support brackets 33 on the positioning base 31 to both sides of the main body of the power cabinet, realizing the lateral auxiliary limit of the main body of the power cabinet and effectively avoiding the lateral vibration or offset of the main body of the power cabinet.

[0044] Further, referring to Figure 7 As shown, a plurality of first support frames 35 are hinged to the outer walls of the two shock-absorbing sleeves 32. One ends of the plurality of first support frames 35 are hinged with positioning pads 36, and a plurality of second support frames 37 hinged with the support brackets 33 are hinged to the outer walls of the plurality of first support frames 35.

[0045] Among them, when in the normal state, the plurality of first support frames 35 and the second support frames 37 are both arranged in an inclined state, and the plurality of first support frames 35 and the second support frames 37 are arranged in an annular and equidistant state in sequence with respect to the outer circumferential surface of the shock-absorbing sleeve 32.

[0046] Specifically, the purpose of such a setting is that when the support bracket 33 is pressed against one side of the power cabinet and a continuous pressing limit is generated on the support bracket 33, the plurality of second support frames 37 can be synchronously deflected to deflect the first support frames 35, so that the plurality of positioning pads 36 are uniformly and symmetrically pressed against both sides of the power cabinet, thereby increasing the support points for the power cabinet, dispersing the weight of the power cabinet to multiple support positions, and dispersing the force when shaking, further effectively avoiding the lateral vibration or offset of the main body of the power cabinet and reducing the risk of damage to the internal components of the power cabinet.

[0047] 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 principles of the present invention shall be included within the protection scope of the present invention.
