[0002] A distribution cabinet is an important component in the power system for distributing electric energy, protecting and controlling other electronic devices, and is commonly used in places with large power consumption such as substations and power stations to ensure the reasonable distribution of electric energy and the normal operation of the power system.

[0003] The design of the distribution cabinet aims to protect the load, monitor and control the circuit. It is internally equipped with protection switches and devices to prevent line short - circuit, overload, leakage and over - voltage. Once a line failure occurs, the power supply can be immediately cut off to ensure the safety of the power supply line and personal safety.

[0004] In the production process of high - and low - voltage distribution cabinets, there is a process of sleeving heat shrinkable tubes on copper bars. The main busbars of the distribution cabinet are generally made of copper bars with a width of 100 - 150 mm and a thickness of 10 - 12 mm. The longest of these copper bars is 6 meters and the heaviest weighs more than 90 kg. Due to the weight, the work of sleeving heat shrinkable tubes on copper bars not only has a high labor intensity but also has a low work efficiency. Content of the Utility Model

[0026] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0027] The present utility model provides a special equipment for sleeving a heat shrinkable tube on a copper busbar as shown in Figures 1 - 7 Figure, which is used to sleeve the heat shrinkable tube 6 on the copper busbar 1, and includes a device main body and accessory components. The device main body includes a base 9, and a vibration table 2 is provided at the top of the base 9, and the copper busbar 1 is placed on the top of the vibration table 2;

[0028] A winch 4 is provided at the rear end of the base 9, a traction rope 5 is connected to the winch 4, a bracket 8 is provided at the front end of the base 9, a heat shrinkable tube reel 7 for winding and placing the heat shrinkable tube 6 is provided on the bracket 8, one end of the heat shrinkable tube 6 is connected to one end of the traction rope 5, and the head of the heat shrinkable tube 6 is sleeved on the left end of the copper busbar 1.

[0029] Horizontal baffles 10 are provided on both lateral sides of the base 9 to prevent the copper busbar 1 from slipping laterally during the vibration process. A limit baffle 3 is provided at the top of the copper busbar 1, and the copper busbar 1 abuts against the limit baffle 3 during the casing process.

[0030] During operation, the heat shrink tube 6 is wound and fixed on the heat shrink tube reel 7, while the copper busbar 1 is placed on the vibrating table 2. The right end of the copper busbar 1 is abutted against the limit baffle 3 to prevent the copper busbar 1 from moving to the right along with the traction force. The traction rope 5 is connected to the heat shrink tube 6. Subsequently, the head of the heat shrink tube 6 is manually sleeved onto a part of the left end of the copper busbar 1. The vibrating table 2 and the hoist 4 are turned on. After the hoist 4 operates, it pulls the traction rope 5. At this time, the heat shrink tube 6 will be gradually sleeved onto the copper busbar 1 under the traction of the traction rope 5. There can be more than two vibrating tables, but it is necessary to ensure that the vibration phases and frequencies of multiple vibrating tables are the same. If electromagnetic vibrators are used, multiple coils should be connected to the same power supply. Since the copper busbar 1 is constantly vibrating up and down under the action of the vibrating table 2, which is equivalent to a semi-suspended state, the heat shrink tube 6 can be easily sleeved on under the action of the traction force, solving the problems of time-consuming, labor-intensive, and low work efficiency when sleeving the copper busbar 1 in a stationary state.

[0031] Before sleeving, the heat shrink tube 6 is cleaned and dusted, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, the accessory components include a dust removal assembly 11 located on the base 9. The dust removal assembly 11 includes a dust suction cylinder 1101 fixedly arranged on the base 9. A detachable cylinder cover 1102 is provided at the top of the dust suction cylinder 1101;

[0032] A detachable filter screen 1107 is provided on the inner wall of the dust suction cylinder 1101. The filter screen 1107 can filter and collect dust. An exhaust fan 1103 for driving air flow is fixedly arranged at the outer end of the dust suction cylinder 1101. The exhaust fan 1103 is located at the bottom of the filter screen 1107.

[0033] A guide pipe 1104 is fixedly arranged at the top of the cylinder cover 1102. One end of the guide pipe 1104 extends to the top of the heat shrink tube 6. A brush hair 1105 is fixedly arranged at the bottom end of the guide pipe 1104. The bottom end of the brush hair 1105 contacts the heat shrink tube 6. When the heat shrink tube 6 moves, it rubs against the brush hair 1105 to remove dust impurities on its surface. A plurality of dust suction holes 1106 are provided at the bottom end of the guide pipe 1104.

[0034] In the working state, the heat shrink tube 6 moves and rubs against the brush hair 1105. The brush hair 1105 brushes off the dust on the surface of the heat shrink tube 6. At the same time, the exhaust fan 1103 is turned on. The exhaust fan 1103 drives air flow and extracts the air in the dust suction cylinder 1101. A negative pressure is generated inside the dust suction cylinder 1101. Therefore, the dust brushed off by the brush hair 1105 is sucked into the inside of the guide pipe 1104 through the dust suction holes 1106, and then enters the dust suction cylinder 1101. Subsequently, the dust in the air is filtered and collected by the filter screen 1107, and the air is discharged under the action of the exhaust fan 1103, thereby using the dust removal assembly 11 to clean the heat shrink tube 6.

[0035] During operation, keep the heat shrinkable tube 6 in a straightened state, as Figure 1 、 Figure 7 shown. A fastening assembly 12 is provided on the front side of the bracket 8. The fastening assembly 12 includes a vertical plate 1201 fixedly arranged on the base 9. A pressing plate 1203 in contact with the heat shrinkable tube reel 7 is provided on one side of the vertical plate 1201. Two springs 1202 are provided between the pressing plate 1203 and the vertical plate 1201. The elastic force of the springs 1202 pushes the pressing plate 1203 into contact with the heat shrinkable tube reel 7, so that the heat shrinkable tube reel 7 has appropriate resistance when rotating.

[0036] During the working process, as the heat shrinkable tube 6 is pulled, the entire heat shrinkable tube reel 7 rotates, and the springs 1202 are in a slightly compressed state. The elastic force of the springs 1202 pushes the pressing plate 1203 against the outer end of the heat shrinkable tube reel 7, so that the rotation of the heat shrinkable tube reel 7 has resistance. Therefore, when pulling the heat shrinkable tube 6, the heat shrinkable tube 6 is straightened, so as to keep the heat shrinkable tube 6 in a straightened state, which is convenient for sleeving it on the copper row 1. The elastic force of the springs 1202 does not need to be too large, as long as it can straighten the heat shrinkable tube 6.

[0037] In order to reduce the vibration during the working process, as Figure 1 、 Figure 3 shown, a bottom plate 13 is provided at the bottom of the base 9. A plurality of buffer air bags 14 are fixedly arranged at the top of the bottom plate 13. The top of the buffer air bags 14 is in contact with the base 9. The elastic force of the buffer air bags 14 can buffer the vibration of the base 9 during the working process.

[0038] Since the vibration table 2 needs to vibrate during the working process, in order to prevent the vibration of the vibration table 2 from affecting the whole device, a bottom plate 13 and buffer air bags 14 are provided at the bottom end of the base 9. The elasticity of the buffer air bags 14 can buffer the vibration of the base 9 and reduce the adverse effects brought by the vibration.

[0039] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
