[0002] The power distribution system is the heart of rail transit and data centers. Dependence on the power supply system is fatal. Once certain power parameter values ​​in the power distribution system exceed the allowable range of equipment operation, it may cause local equipment failure or even large-scale paralysis, which is enough to cause serious consequences for the entire rail transit and data center operating systems. Due to its high importance, the requirements for power distribution equipment are getting higher and higher. The development of modern industrial technology has also put forward higher requirements on the reliability of distribution system operation and its intelligent management.

[0003] A modular power distribution cabinet is disclosed in the patent with announcement number CN217656289U. By setting up multiple power distribution cabinet frames, bottom plates and top plates, the multiple power distribution cabinet frames can be connected together by bolts and nuts. The appropriate number of power distribution cabinet frames can be selected according to actual usage to combine the multiple power distribution cabinet frames together. However, during the use of the power distribution cabinet, the internal electrical components usually generate heat. If the heat is not dissipated in time, the service life of the internal components of the power distribution cabinet will be reduced. Utility Model Content

[0004] The purpose of this application is to address the above-mentioned problems existing in the prior art and to propose a modular, intelligent, and precise integrated power distribution cabinet for rail transit.

[0005] The present application can be implemented through the following technical solution: A modular, intelligent, precise integrated power distribution cabinet for rail transit, comprising a U-shaped shell, a sealing plate, and a cooling fan.

[0006] In the above technical solution, the distribution cabinet is modularized by providing multiple U-shaped shells and two sealing plates, so that the distribution cabinet is easy to carry. A cooling fan is provided to dissipate heat from the electrical components in the distribution cabinet. Ventilation holes are provided to facilitate air circulation and allow hot air to flow out, thereby achieving a better heat dissipation effect.

[0007] Furthermore, each of the U-shaped shells is formed with connecting plates at both ends in the height direction, the connecting plate away from the ground is provided with a plurality of through holes, and the lower end of the connecting plate close to the ground is formed with a plurality of connecting rods, the plurality of connecting rods can correspond one by one to the plurality of through holes, the connecting rods are slidably connected with abutment blocks that can slide along the radial direction of the connecting rods, the abutment blocks are spaced apart from the connecting plates, and the connecting rods can be passed through the through holes on the connecting plate below themselves, so that the abutment blocks can abut against the lower surface of the connecting plate below themselves.

[0008] In the above technical solution, when connecting multiple U-shaped shells together, the abutment block is first placed in the connecting rod, and then several connecting rods are passed through several holes on the connecting plate of another U-shaped shell one by one. Then, the abutment block on the connecting rod is pulled outward so that the abutment block abuts against the lower surface of the connecting plate, so that the positions of the two U-shaped shells can be relatively fixed.

[0009] Furthermore, a spring is provided in the connecting rod to force the abutment block to extend out of the axial outer wall of the connecting rod, and the abutment block is formed with an inclined surface, which can contact the through hole to make the abutment block retract into the connecting rod.

[0010] In the above technical solution, during the process of the connecting rod passing through the penetration hole, the inclined surface can contact the penetration hole so that the abutment block retracts into the connecting rod. After the abutment block passes through the penetration hole, the spring can force the abutment block to extend relative to the axial outer wall of the connecting rod so that the abutment block abuts against the lower surface of the connecting plate on the U-shaped shell located below, so that the abutment block can limit the connecting plate.

[0012] In the above technical solution, by providing a mounting plate and opening connecting holes through the mounting plate, the connecting plates of adjacent cabinet doors can be used to pass the same bolt, so as to facilitate connecting multiple cabinet doors.

[0013] Furthermore, a connection hole is opened around the sealing plate, and the connection hole can be opposite to the penetration hole, and the connection rod can be penetrated through the connection hole so that the abutment block abuts against the lower surface of the sealing plate.

[0014] In the above technical solution, the connection rod closest to the ground is inserted into the connection hole on the sealing plate, and the abutment block is abutted against the lower surface of the sealing plate, so that the position of the sealing plate can be fixed.

[0016] In the above technical solution, a brake universal wheel is provided on the sleeve to facilitate the movement of the overall structure.

[0017] Furthermore, the upper end of the sleeve can abut against the lower surface of the sealing plate to fix the position of the sealing plate.

[0018] In the above technical solution, when the sealing plate is installed on the connecting plate closest to the ground, the connecting rod is first passed through the connecting hole to make the abutment block abut against the lower surface of the sealing plate, and then the sleeve is inserted into the connecting rod. The sleeve can press the abutment block so that the abutment block retracts into the slide groove until the upper end of the sleeve abuts against the lower surface of the sealing plate. At this time, the position of the sealing plate close to the ground, that is, the position relative to the U-shaped shell, is fixed. This design can make the overall structure more stable when the length of the connecting rod is constant.

[0019] Furthermore, a dust shield is provided at the ventilation hole, and the dust shield is located above the ventilation hole and installed on the outer wall of the frame.

[0020] In the above technical solution, by providing a dust shield, the possibility of dust outside the U-shaped shell entering the U-shaped shell through the ventilation holes can be reduced.

[0028] Please refer to the attached drawings in the instruction manual. Figure 1 One embodiment of the present application provides a modular, intelligent, and precise integrated power distribution cabinet for rail transit, including four U-shaped shells 1, which are stacked vertically and can be connected internally. The structure on a U-shaped shell 1 is now described. The U-shaped shell 1 is hinged with a cabinet door 2, and the cabinet door 2 and the U-shaped shell 1 can be closed into a "U" shape. Two threading holes are provided through the end of the U-shaped shell 1 away from the cabinet door 2 to facilitate the entry of external wires into the U-shaped shell 1. The two U-shaped shells 1 that are farthest apart can both contact with a sealing plate 3, the upper end of the U-shaped shell 1 away from the ground can contact with a sealing plate 3, and the lower end of the U-shaped shell 1 close to the ground can contact with a sealing plate 3, so that the interior of the overall structure can be closed.

[0029] Please refer to the attached drawings in the instruction manual. Figure 1 and Figure 2 A cooling fan 4 is detachably mounted on the side wall of each U-shaped shell 1. Three ventilation holes 11 are provided on the side wall of the U-shaped shell 1 opposite to the cooling fan 4. The operating temperature of the electrical components in the power distribution cabinet is sometimes high. The cooling fan 4 is provided to dissipate heat to extend the service life of the electrical components. The ventilation holes 11 are provided so that air can circulate and the heat dissipation effect is better. A dust shield 12 is provided above each ventilation hole 11. The dust shield 12 is tilted and is close to one end of the U-shaped shell 1 away from the ground. The dust shield 12 can reduce the possibility of dust entering the U-shaped shell 1 through the ventilation holes 11.

[0030] Please refer to the attached drawings in the instruction manual. Figure 2 and Figure 3, at both ends of the U-shaped housing 1 in the height direction, a connecting plate 5 is formed. The connecting plate 5 is in a "凵" shape and is horizontally arranged. The connecting plate 5 far from the ground is provided with several through holes 51 along its length direction. At the lower end of the connecting plate 5 close to the ground, several connecting rods 6 are formed along its length direction. The connecting rods 6 are vertically arranged. The several connecting rods 6 are respectively aligned with the several through holes 51. A sliding groove 61 is formed on the connecting rod 6. The depth direction of the sliding groove 61 is consistent with the radial direction of the connecting rod 6. A contact block 7 is slidably connected to the sliding groove 61. The contact block 7 can slide along the depth direction of the sliding groove 61. A spring 17 is arranged in the sliding groove 61 to force the contact block 7 to extend out of the outer wall of the axial direction of the connecting rod 6. The spring 17 is a compression spring. There is a gap between the upper end of the contact block 7 and the lower surface of the connecting plate 5. The upper end of the contact block 7 can be in contact with the lower surface of the connecting plate 5 on another U-shaped housing 1. An inclined surface 71 is formed on the contact block 7. The end of the inclined surface 71 close to the ground is close to the outer wall of the axial direction of the connecting rod 6. The connecting rod 6 can pass through the through hole 51 of the connecting plate 5 at the upper end of another U-shaped housing 1. When it is necessary to install multiple U-shaped housings 1 together, directly press down several connecting rods 6 of one U-shaped housing 1 until several contact blocks 7 are simultaneously in contact with the lower surface of the connecting plate 5 formed on another U-shaped housing 1. By setting the inclined surface 71, when the inclined surface 71 contacts the through hole 51, the contact block 7 can retract into the sliding groove 61, and when the inclined surface 71 leaves the through hole 51, the contact block 7 can extend out relative to the outer wall of the axial direction of the connecting rod 6 to limit the connecting plate 5.

[0031] Please refer to the Figure 1 description drawings. At the edge of each sealing plate 3, a plurality of connecting holes 81 are formed. The several connecting holes 81 can be respectively aligned with the several through holes 51 and have the same size as the through holes 51. The thickness of the sealing plate 3 is the same as the thickness of the connecting plate 5. The connecting hole 81 and the through hole 51 can pass through the same bolt 13. The bolt 13 is threadedly connected with a nut 14 so that the sealing plate 3 is fixed relative to the U-shaped housing 1 far from the ground.

[0032] Please refer to the Figure 2 and Figure 4, several connecting rods 6 closest to the ground can be passed through several connecting holes 81 of another sealing plate 3 in a one-to-one correspondence, and each connecting rod 6 closest to the ground is plugged into a sleeve 9, and a brake universal wheel 10 is installed at the bottom of the sleeve 9. The sleeve 9 can press the abutment block 7 so that the abutment block 7 retracts into the slide groove 61 and the upper end of the sleeve 9 can contact the sealing plate 3. When in use, the connecting rods 6 of several U-shaped shells 1 close to the ground are passed through the connecting holes 81 opened in the sealing plate 3 in a one-to-one correspondence, so that several abutment blocks 7 are all abutted against the lower surface of the sealing plate 3, and then the sleeve 9 is plugged into the connecting rod 6 close to the ground so that the abutment block 7 retracts into the slide groove 61 until the sleeve 9 abuts against the lower surface of the sealing plate 3 close to the ground. At this time, the sealing plate 3 close to the ground is fixed relative to the position of the U-shaped shell 1. Both ends of the cabinet door 2 close to and away from the ground are formed with mounting plates 8, and a plurality of connecting holes 81 are formed through the mounting plates 8. The connecting holes 81 of two adjacent cabinet doors 2 can be penetrated by the same bolt 15, and the bolt 15 is threadedly connected with the same nut 16, so that the positions of the four cabinet doors 2 are relatively fixed.

[0033] The working principle of this embodiment is as follows: first, four U-shaped shells 1 are stacked and installed together, and then a sealing plate 3 is connected to the connecting plate 5 farthest from the ground through bolts 13 and nuts 14, and a connecting rod 6 close to the ground is inserted into the connecting hole 81 of another sealing plate 3, and then the sleeve 9 is inserted into the connecting rod 6 close to the ground until the upper end of the sleeve 9 abuts against the lower surface of the sealing plate 3.
