The electrical components 13 here include but are not limited to dual power supply switching switches, circuit breakers, AC contactors, thermal relays, intermediate relays, etc. These electrical components 13 need to be connected in sequence, and some also need to be equipped with detectors and indicator lights for real-time status feedback. This part belongs to the existing mature technology and will not be repeated here. The bottom plate 17 of the box body is provided with a mounting flange 4 for fixed connection, and the mounting flange 4 has threaded holes for passing bolts. A backup power supply 16 is also provided in the box body shell 1, and a short circuit detector and an indicator light are provided on the backup power supply 16.

[0025] As a preferred method, Figure 2 and Figure 5-7As shown, the box shell 1 is provided with a fixed baffle 201 and a movable baffle 2, the fixed baffle 201 is connected to the middle layer plate 10, and the middle layer plate 10 is rotatably connected in turn through the hinge rod 9, the middle layer plate 10 is provided with a T-shaped convex rib 131, the electrical component 13 is provided with an accessory slot 101, and the accessory slot 101 has the same cross-sectional shape as the T-shaped convex rib 131, the electrical component 13 is wedged and connected to the middle layer plate 10, the side end face of the middle layer plate 10 in the thickness direction is provided with a hinge slot 901, and the edge of the hinge rod 9 is provided with a side convex rib 902 along the axis, and the side convex rib 902 is wedged and connected to the hinge slot 901.

[0026] The implementation method is as follows: according to the needs of connecting different power box electrical components 13, the number of electrical components 13 is also different. Since the accessory slot 101 and the T-shaped convex rib 131 are connected as a moving pair, the electrical components 13 can be moved along the Figure 6 The middle layer 10 is moved horizontally in the left and right directions until it is disconnected from the middle layer 10, or the reverse operation is performed to install different electrical components 13. After the electrical components 13 are installed, the electrical components 13 are connected with the wires 14, and then the middle layer 10 is swung so that the middle layer 10 connected to a plane is as shown in FIG. Figure 7 The angle is formed in the middle to shorten the occupied space in the length direction and increase the space utilization. The position 13A here is the position of the electrical component 13 before bending, which is convenient for installing the wire 14 but has low space utilization. It is worth noting that the right angle here is for intuitive reference. In actual applications, a larger or smaller angle can be bent to adapt to different electrical component 13 configurations.

[0027] As a preferred method, Figure 4 As shown, the cooling clamp 11 structure is a multi-section annular tube with a notch, a clamp notch 113 is provided on one side of each annular tube, a cooling channel 111 is provided in the annular tube wall, the cooling ducts in adjacent annular tubes are connected, and the end of the cooling channel 111 is connected to the cooler 18 through a cooling pipe 112.

[0028] The implementation method is as follows: due to the presence of the clamp notch 113, the annular tube has a certain degree of deflection, and the wire 14 can pass through the clamp notch 113 during installation and then be sleeved in the cooling clamp 11. After the power box is shrunk, the gap between the electrical component 13 or the wire 14 and the electrical component 13 is small, and there is a problem of heat dissipation. When the coolant in the cooler 18 passes through the cooling channel 111, it will take away the heat of the wire 14 sleeved in the cooling clamp 11, thereby avoiding damage to the equipment.

[0029] As a preferred method, Figure 1-5As shown, the sliding cover plate 8 is provided with sandwich plates 801 in pairs, and a sliding cabin 803 is provided between the sandwich plates 801. The sliding cabin 803 is fitted and docked with the sliding layer plate 806. The sliding layer plate 806 is provided with a connecting block 812 at one end located in the sliding cabin 803. The connecting block 812 is provided with a buckle slide groove 811. The buckle slide groove 811 is slidably connected with the locking buckle 805. The locking buckle 805 is provided in pairs. The locking buckle 805 5, a return spring 809 is arranged between the buckle slide 811 and the locking knob 804 is arranged along the radial direction, and the locking knob 804 is provided with a spiral locking convex ridge 808, and the locking convex ridge 808 abuts against the locking buckle 805, and the movable end of the locking buckle 805 abuts against the inner wall of the sandwich plate 801, and the sandwich plate 801 is provided with a sandwich slide 802 along the width direction, and the end of the locking convex ridge 808 is clamped in the sandwich slide 802. The inner wall of the sandwich plate 801 is provided with an engagement groove 813, and the engagement groove 813 is a triangular cross-sectional transverse groove arranged continuously and evenly, and the locking buckle 805 is provided with an engagement convex ridge 810, and the cross-sectional morphology of the engagement convex ridge 810 is consistent with the engagement groove 813, and the engagement convex ridge 810 is wedged and clamped with the engagement groove 813.

[0030] As a preferred embodiment, a sliding support 3 is provided at the lower end of the movable baffle 2, and a slide rail notch is opened in the sliding support 3. The bottom plate 17 of the box body is provided with a translational slide rail 20, and the translational slide rail 20 is wedged and docked with the slide rail notch to form a moving pair. The middle layer plate 10 is detachably connected to the lining bracket 19, and a slide rail notch is also provided at the movable end of the lining bracket 19. The lining bracket 19 is connected to the translational slide rail 20 by wedging the slide rail notch to form a moving pair.

[0031] The implementation method is as follows: after the installation of the lines and the disassembly of the electrical components 13 are completed, the box shell 1 is pushed from the side of the movable baffle 2, and the sliding support 3 slides along the translation rail 20. At the same time, the sliding layer plate 806 fixedly connected to the upper end of the movable baffle 2 translates in the sliding cabin 803 of the sliding cover 8, so that the entire box cover 5 is shortened. If the internal electrical components 13 meet the shorter box length, the movable baffle 2 is continued to be pushed, and the sliding cover 8 is further moved in the sliding cabin 803 in the second sliding plate 7. When the shorter box length is met, the second sliding plate 7 is further moved in the sliding cabin 803 in the third sliding plate 6 until the box is minimized.

[0032] When the middle layer plate 10 reaches the adapted position, the locking knob 804 is rotated to make the locking convex ridge 808 abut against the locking buckle 805, so that the meshing convex ridge 810 on the locking buckle 805 meshes with the meshing slot 813, so that the sliding cover plate, the second sliding plate, and the third sliding plate are fastened. When the locking convex ridge 808 and the locking buckle 805 are out of abutment, the return spring 809 pulls the locking buckle 805 inward to make the meshing convex ridge 810 and the meshing slot 813 out of a meshing state, and the aforementioned movable cover plate returns to a slidable state.

[0033] The bottom plate 17 of the box is fixedly installed at the working position, but its structure is flat, which does not affect the efficiency of space utilization. Figure 2 In the embodiment, a waterproof gasket 807 is provided between the sliding layer plate 806 and the sandwich plate 801 to block the vent holes on the sliding cover plate 8.

[0034] As a preferred method, Figure 6 In the figure, a winding roller 15 is provided at one end of the middle layer plate 10 near the fixed baffle 201, which is mainly used to store spare wires 14 and the longer wires 14 that need to be reserved during installation are wound around the winding roller 15, ensuring that the fixed baffle 201 and the movable baffle 2 are both provided with ventilation holes, and the fixed baffle 201 is provided with a through hole for passing the power line, and the through hole is provided with a power plug 12.
