[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet, metering cabinet, etc. As the final equipment in the distribution network system, the distribution cabinet is generally used in places where the load is relatively dispersed and there are not many circuits. The main function of the distribution cabinet is to receive the electric energy of the upper distribution equipment and distribute it to the next level of electrical equipment or branch lines. At the same time, it also has a control function, which can open or cut off the circuit and manage the power supply of each power point.

[0003] At present, when the existing distribution cabinet is in use, the required components are usually installed inside the cabinet. However, during the use of the distribution cabinet, it may be necessary to add components or repair components in the distribution cabinet at a later stage. The size of the existing distribution cabinet is basically fixed in the design and manufacturing stage, and its internal space cannot be adjusted. There is not enough space to accommodate the newly added components. Therefore, when new equipment needs to be added, it is generally necessary to redesign and manufacture a new cabinet for modification. In the process of repairing the internal components, the components are usually installed directly inside the cabinet. During maintenance, it is necessary to enter the cabinet for operation. Due to the cramped space, it is inconvenient to disassemble and repair. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] An adjustable power distribution switch cabinet, such as Figure 1-Figure 8 As shown, it includes a base plate 1, a cabinet 2, a shutter 3, a door panel 4, an exhaust mechanism, an expansion mechanism and a mounting mechanism. The cabinet 2 is placed on the top of the base plate 1. Air inlets are opened on the upper parts of the left and right sides of the cabinet 2. Shutters 3 are arranged at the air inlets. The front side of the cabinet 2 is rotatably connected to the door panel 4. The cabinet 2 is provided with an exhaust mechanism for gas exhaust. An expansion mechanism is provided between the base plate 1 and the cabinet 2. A mounting mechanism for installing electrical components is provided between the expansion mechanism and the cabinet 2.

[0033] like Figure 5 As shown, the exhaust mechanism includes an air outlet pipe 51 and a fan 52. A plurality of air outlet pipes 51 are connected at intervals at the upper rear side of the cabinet 2. The air outlet pipes 51 connect the inside of the cabinet 2 with the outside of the cabinet 2. The fan 52 is installed on the air outlet pipes 51.

[0034] like Figure 3-Figure 5 As shown, the expansion mechanism includes an expansion frame 61, a swing plate 62 and a cylinder 63. The top of the base plate 1 is connected to the expansion frame 61, and the expansion frame 61 is slidably connected to the cabinet 2. The front side of the expansion frame 61 is rotatably connected to the swing plate 62. Cylinders 63 are installed in the middle of the left and right side walls of the cabinet 2. The telescopic rod of the cylinder 63 is connected to the expansion frame 61, so that when the telescopic rod of the cylinder 63 is extended or retracted, the reaction force of the expansion frame 61 can drive the cylinder 63 itself to move up and down.

[0035] like Figure 6-Figure 8As shown, the installation mechanism includes a guide rail 1 71, a guide rail 2 72, a mounting plate 73 and a locking structure. The left and right sides of the bottom of the expansion frame 61 are connected to the guide rail 1 71, and the left and right sides of the cabinet 2 are connected to the guide rail 2 72. The guide rail 1 71 and the guide rail 2 72 are slidably connected. The mounting plate 73 is provided with a locking structure, and the mounting plate 73 can be installed on the guide rail 1 71 or the guide rail 2 72 through the locking structure.

[0036] like Figure 8 As shown, the locking structure includes a connecting frame 731, a locking frame 732 and an elastic member 733. The left and right sides of the rear side of the mounting plate 73 are connected to the connecting frame 731. The locking frame 732 is slidably connected to the connecting frame 731. Two elastic members 733 are connected between the locking frame 732 and the connecting frame 731. The elastic member 733 is a return spring. Locking grooves are provided on the guide rail 1 71 and the guide rail 2 72. When the guide rail 1 71 and the guide rail 2 72 overlap, the locking grooves of the guide rail 1 71 and the guide rail 2 72 can also overlap with each other. The locking frame 732 can be inserted into the locking groove, so that the mounting plate 73 is installed on the guide rail 1 71 or the guide rail 2 72.

[0037] When the power distribution cabinet is needed, switches and other components can be installed on the mounting plate 73. During use, if internal switches and other components need to be added due to an increase in electrical equipment, and the original layout has filled the space in the power distribution cabinet, the space of the entire power distribution cabinet is limited. At this time, the locking frames 732 on both sides can be pulled closer to each other, and the elastic member 733 is stretched to disengage the locking frame 732 from the locking groove, and then the mounting plate 73 is taken out. After taking it out, the telescopic rod of the cylinder 63 can be controlled to extend. At this time, the expansion frame 61 is connected to the bottom plate 1 and cannot move downward, so that the cylinder 63 moves upward, and the upward movement of the cylinder 63 can drive The cabinet body 2 moves upward to expand the space of the cabinet body 2. After the cabinet body 2 moves upward, it can drive the swing plate 62 to swing to block the space between the front side of the expansion frame 61 and the cabinet body 2. When the cabinet body 2 moves upward, it can drive the guide rail 1 71 and the guide rail 2 72 to slide relative to each other. After the distribution cabinet is expanded, the locking frame 732 can be controlled to align with the locking groove again, and then the locking frame 732 is released. Under the action of the elastic member 1 733, the locking frame 732 is inserted into the locking groove to fix the mounting plate 73. Then the components can be installed. In this way, when using the distribution cabinet, the space inside the distribution cabinet can be expanded to cope with the situation where there is a sudden need to increase electrical equipment.

[0038] like Fig. 9 and Fig.10As shown, it also includes an automatic unfolding mechanism, which includes a connecting rope 81, a threaded rod 82, a winding drum 83, an elastic member 84, a sliding block 85 and a connecting rod 86. The front and rear sides of the lower part of the expansion frame 61 are rotatably connected with the threaded rod 82, and the right side of the threaded rod 82 is connected to the winding drum 83. The connecting rope 81 is wound on the winding drum 83. The upper part of the connecting rope 81 is connected to the middle position of the cabinet 2. An elastic member 84 is connected between the winding drum 83 and the expansion frame 61. The elastic member 84 is a volute spring. The threaded rod 82 is threadedly connected with a sliding block 85. The sliding block 85 is slidably connected to the expansion frame 61. A connecting rod 86 is hingedly connected between the sliding block 85 and the bottom of the swing plate 62.

[0039] When the cabinet 2 moves upward, it can drive the connecting rope 81 to move upward. When the connecting rope 81 moves upward, it can pull the winding drum 83 to rotate. When the winding drum 83 rotates, it can drive the threaded rod 82 to rotate. The elastic member 84 is deformed. When the threaded rod 82 rotates, it can drive the sliding block 85 to move forward through the thread. When the sliding block 85 moves forward, it can squeeze the swing plate 62 through the connecting rod 86 to swing upward to block the front side of the expansion frame 61. In this way, the swing plate 62 can be automatically unfolded without manual control, which is more convenient to operate.

[0040] like Fig.11 As shown, an air guide mechanism is also included, and the air guide mechanism includes an air guide frame 91, a filter 92 and an air guide pipe 93. The left and right side walls in the cabinet 2 are connected to the air guide frames 91, and the two air guide frames 91 cover two air inlets respectively. The filter 92 is installed in the air guide frame 91, and a plurality of air guide pipes 93 are evenly spaced and connected to the bottom of the air guide frame 91. The air guide pipe 93 is a telescopic pipe, and the lower part of the air guide pipe 93 passes through the expansion frame 61 and is connected to the inner wall of the expansion frame 61.

[0041] When the fan 52 operates to make the air outlet pipe 51 discharge the gas in the cabinet 2, the air pressure in the cabinet 2 decreases, and air will be sucked in through the air inlet. At this time, the gas will enter the air guide frame 91. The filter 92 can filter impurities in the gas, and the gas in the air guide frame 91 will enter the lower part of the expansion frame 61 through the air guide pipe 93. When the air outlet pipe 51 discharges the gas, it can suck the gas upward through the lower part of the expansion frame 61, and finally discharge it through the air outlet pipe 51. The gas will pass through the entire cabinet 2 from bottom to top, thereby dissipating the heat of the components in the cabinet 2. During the treatment, the gas circulation space is increased, and the components in the entire cabinet 2 can be cooled, and the treatment effect is better.

[0042] like Fig.12As shown, a pull rod 101 is also included. The two locking frames 732 of the same mounting plate 73 are both connected with the pull rod 101. The pull rod 101 is slidably connected to the mounting plate 73. Pulling the pull rod 101 can drive the locking frame 732 to move, which is more convenient to operate.

[0043] like Fig.13 As shown, it also includes a guide rod 111 and a rubber positioning ring 112. The rear side of the mounting plate 73 is connected to two upper and lower guide rods 111, and a plurality of rubber positioning rings 112 are slidably connected to the guide rod 111.

[0044] When the wires of the components are connected to each other, the wire group can be passed through the gap between the guide rod 111 and the mounting plate 73, and then the two rubber positioning rings 112 close to each other can be pulled to move so that the two rubber positioning rings 112 close to each other respectively press against the two sides of the wire group to assist in positioning the wire group.

[0045] It should be understood that the above description is only for exemplary purposes and is not meant to limit the present invention. Those skilled in the art will appreciate that variations of the present invention will be included within the scope of the claims herein.
