Description

Technical Field

[0001] The invention relates to the technical field of bus ducts, and in particular to a water-seepage-resistant bus duct connection device. Background Art

[0002] In the early days of building and industrial power supply, modern high-rise buildings and large workshops required huge amounts of electrical energy. In the face of the huge loads of hundreds of amperes of strong current, it was necessary to use safe and reliable conduction equipment. The busbar system was a good choice. However, with the increase in electrical equipment and power, traditional wires were difficult to meet the needs due to their limited current carrying capacity and complex wiring. In order to efficiently transmit large currents, busbars came into being. Busbars are conductors that collect and distribute electrical energy, and their appearance solved the problem of large current transmission.

[0003] In the existing technology, in order to adapt to the needs of economical and reasonable wiring of buildings with increasing heights and large-scale factories. In the installation of bus duct products, due to the lack of relative positioning parts.

[0007] As a preferred technical solution of the present invention, the gear is meshed with the rack.

[0008] As a preferred technical solution of the present invention, the display knob is connected to the insulating partition through a gear, and the gear is hinged to the rotating column.

[0009] As a preferred technical solution of the present invention, the fixing assembly includes a first fixing plate located on the outer wall of the waterproof plate, the outer wall of the first fixing plate is provided with a pressing column, one end of the pressing column is provided with a spring, the outer wall of the first fixing plate is provided with a second fixing plate, the outer wall of the second fixing plate is provided with a second limiting groove, and the outer wall of the second limiting groove is provided with a second sliding rod.

[0010] As a preferred technical solution of the present invention, the waterproof plate and the fixing assembly are located on the same horizontal plane.

[0011] As a preferred technical solution of the present invention, the waterproof cover is made of waterproof rubber material.

[0012] As a preferred technical solution of the present invention, the bottom of the push column is connected to the waterproof strip.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The anti-seepage busbar duct connection device is provided with a plurality of limit grooves on the connecting side plates, the limit grooves are provided with racks, and the outer walls of the connecting side plates are provided with gears. When the cover plate is connected to the inside of the limit groove from top to bottom, the gear is meshed with the rack. When the gear rotates on the rack in the limit groove, the side display knob is driven to rotate. Since a rotating column is connected to one side of the display knob, the rotating column can adjust the tightness of the inner wall insulating partition. In the existing technology, once the adjusting bolt is loosened, the connection structure of the busbar connection duct will be loosened as a whole. This connection structure lacks certain stability and sealing. When the side plate fits with the bottom cover plate, the adjustment knob of the side wall just reaches the appropriate tightness, and the tightness can be checked in time. A tightness indicator icon of the internal insulating partition is also provided near the adjusting knob, which ensures the stability of the equipment at the first time. The anti-seepage bus duct connection device is provided with a fixing component on the outer wall of the limit component. When the gear slides to the bottom with the rack, the limit screw on the push rod on the buckle slides up and down on the side limit groove, so that the slider is connected to the outer wall of the gear, which effectively prevents the instability of the internal structure caused by the loosening of the gear. The buckle connection allows the equipment to withstand greater mechanical stress and vibration, and is not prone to loosening, deformation or falling off. For example, a dense bus duct supported by a tough metal shell can remain stable under high-power impact and is suitable for large-span installation. The stable structure makes it less likely to malfunction during long-term use, reduces the frequency of repair and replacement, and reduces maintenance costs. For example, a modularly designed bus duct is convenient for maintenance and management, and reduces maintenance costs.

[0014] 3. The anti-seepage busbar duct connection device is also provided with a waterproof partition on the outside of the conductor group. The waterproof partition is made of polyvinyl chloride, so that the port joint is waterproof. A fixing component is provided at the front end of the partition. The front pressing column is pressed to move the conductor group to the middle and cross-fix it. The spring behind the pressing column is pushed and retracted at the bottom, so that the outer wall slide bar slides along the limit groove for effective fixation, so that it can be better fixed, reducing shaking and looseness caused by impact. The stable structure makes it less likely to malfunction in long-term use, reduces the frequency of maintenance and replacement, reduces maintenance costs, and facilitates maintenance and management. Secondly, good anti-seepage performance can keep the inside of the connection groove dry, provide a stable working environment for the insulating material, thereby enhancing the insulation performance, which helps to improve the voltage resistance level of the busbar connection groove and reduce the probability of electrical accidents. Water easily carries dust and dirt, forming stains on the surface of the busbar connection groove. The anti-water seepage device can prevent moisture from entering, thereby reducing the adhesion of stains and keeping the connection groove clean. At the same time, it can effectively prevent moisture from penetrating into the connection groove, avoiding the busbar conductor from getting damp, rusting or corroded due to water seepage, reducing the risk of electrical failures such as short circuit and leakage caused by moisture, and ensuring the safe and stable operation of the power system.

A rack 42 is provided on the inner wall of the limiting column 41, and the rack 42 is meshed with the gear 10. When the upper end connecting cover plate 2 drives the connecting side plate 7 to move downward, the gear 10 on the outer wall of the connecting side plate 7 rotates on the rack 42. The rack 42 not only effectively limits the gear 10, but also ensures that the speed of the upper end connecting cover plate 2 will not be too fast during the downward movement, thereby reducing the locking phenomenon of internal components caused by excessive speed. When the gear 10 rotates on the rack 42 in the limiting groove, it drives the side display knob 8 to rotate.

The stable structure makes it less likely to fail in long-term use, reduces the frequency of repairs and replacements, and reduces maintenance costs. For example, the modularly designed bus duct is convenient for maintenance and management, reduces maintenance costs, has strong mechanical stability and can withstand greater mechanical stress and vibration, and is not prone to loosening, deformation or falling off. For example, the dense bus duct supported by a tough metal shell can remain stable under high-power impact and is suitable for large-span installation.

[0019] See also Figure 5The buckle 5 includes a top fixing plate 51 located on the outer wall of the side limit assembly 4, the outer wall of the top fixing plate 51 is fixedly connected to a side fixing column 52, the outer wall of the side fixing column 52 is provided with a rotating shaft 53, the outer wall of the rotating shaft 53 is provided with a lever 54, the inner wall of the lever 54 is provided with a first sliding rod 59, the outer wall of the first sliding rod 59 is provided with a first limiting groove 510, the outer wall of the first limiting groove 510 is provided with a limiting screw 58, the bottom of the limiting screw 58 is provided with a circular connecting column 57, the bottom of the circular connecting column 57 is provided with a T-shaped connecting column 55, and the bottom of the T-shaped connecting column 55 is provided with a bottom fixing plate 56, wherein, when the side fixing plate is in contact with the bottom After the cover plate is closed, the lever 54 is pulled to make the screw 58 rotate on the first limit groove 510. At this time, the sliding block pops out of the outer wall of the fixing plate 56 and moves inward to engage with the gear rotation of the inner wall of the limit assembly to prevent the internal structure from being loose due to gear transmission. The safety performance is safe and reliable, and safety accidents such as short circuit and leakage caused by unstable connection can be prevented to ensure the safety of personnel and equipment. For example, the insulating guard plate in the connector can isolate the inter-phase conductive connection row to avoid short circuit, which effectively improves the work efficiency and stability of the equipment. The stable structure makes it less likely to fail in long-term use, reduces the frequency of repair and replacement, and reduces maintenance costs.

[0020] See also Figure 1 The first limit groove 510 is threadedly connected to the limit screw 58, and the side fixing column 52 is rotationally connected to the lever 54. When the operator pushes the lever 54, the lever 54 rotates on the side fixing column 52, thereby driving the limit screw 58 to rotate. The limit screw 58 effectively limits the position and speed of the lever 54, preventing the internal components from locking at various connections due to excessive movement speed, thereby greatly improving the stability of the equipment.

[0021] See also Figure 4 The gear 10 is meshed with the rack 42. When the gear 10 enters the limit assembly along with the side fixing plate, the gear 10 is meshed with the rack 42, so that the tightness of the inner wall insulating partition can be adjusted.

[0022] See also Figure 2 The display knob 8 is connected to the insulating partition 11 through a gear 10, and the gear 10 is hinged to the rotating column 19. Since one side of the display knob 8 is connected to the rotating column 19, the rotating column can adjust the tightness of the inner wall insulating partition. In the existing technology, once the adjusting bolt is loosened, the connection structure of the busbar connection groove will be loosened as a whole. This connection structure lacks certain stability and sealing. When the side panel and the bottom cover are fitted together, the adjustment knob of the side wall just reaches the appropriate tightness. The tightness can be checked in time. There is also a tightness indicator icon 9 of the internal insulating partition near the adjusting knob, which ensures the stability of the equipment at the first time.

[0023] See also Figure 8 The fixing assembly 18 includes a first fixing plate 181 located on the outer wall of the waterproof plate 12, a pressing column 182 is provided on the outer wall of the first fixing plate 181, a spring 183 is provided at one end of the pressing column 182, a second fixing plate 184 is provided on the outer wall of the first fixing plate 181, a second limiting groove 185 is provided on the outer wall of the second fixing plate 184, and a second sliding rod 186 is provided on the outer wall of the second limiting groove 185, wherein, when the waterproof plate 12 moves inwardly, the conductor group 13 is cross-connected with the insulating partition 11, and when the top of the first fixing plate 181 moves to the circular protrusion provided on the inner wall of the connecting side plate 7, the pressing column 182 is pushed backward due to pressure, and since a spring 183 is provided at the bottom of the pressing column 182, the second sliding rod 186 moves on the second fixing plate 184 along the second limiting groove 185, so that the insulating partition 11 and the conductor group 13 are fixed more firmly, reducing shaking and looseness caused by impact, and the stable structure makes it not easy to fail in long-term use, reducing the frequency of maintenance and replacement.

[0024] See also Figure 1 The waterproof board 12 and the fixing component 18 are located in the same horizontal plane, wherein the fixing component 18 is provided at the front end of the waterproof board 12. When the waterproof board 12 is connected forward, the setting of the fixing component 18 makes the internal structure of the equipment more stable and the connection between structures is closer, which can prevent safety accidents such as short circuit and leakage caused by unstable connection, and ensure the safety of personnel and equipment. For example, the insulating guard plate in the connector can isolate the inter-phase conductive connection row to avoid short circuit, and can withstand greater mechanical stress and vibration, and is not prone to loosening, deformation or falling off. For example, the dense bus duct supported by a tough metal shell can remain stable under high-power impact and is suitable for large-span installation.

[0025] See also Figure 8 The waterproof cover plate 16 is made of waterproof rubber material, wherein the waterproof cover plate 16 is made of waterproof polyvinyl chloride, which effectively prevents water from penetrating and reduces the corrosion and damage of internal components caused by moisture. Therefore, the maintenance work is relatively less, so that the busbar connection slot can maintain a stable working state in various harsh environments, reducing failures caused by water seepage. At the same time, during maintenance, the dry internal environment is also convenient for staff to inspect and repair, improving maintenance efficiency. Water can easily carry dust and dirt and form stains on the surface of the busbar connection slot. The anti-water seepage device can prevent water from entering, thereby reducing the adhesion of stains and keeping the connection slot clean.

[0026] See also Figure 1The bottom of the push column 182 is connected to the waterproof strip 17. When the push column 182 is pushed, a spring is provided at the other end. When the spring is subjected to force, the push rod is pushed, so that the spring on the inner wall of the waterproof strip 17 is expanded and contracted, and the waterproof strip 17 is ejected to the front end of the conductor group 13, so that the waterproof effect is greatly increased, and it can effectively prevent moisture from penetrating into the connecting groove, avoid the busbar conductor from getting damp, rusting or corroded due to water seepage, reduce the risk of electrical faults such as short circuit and leakage caused by moisture, ensure the safe and stable operation of the power system, prevent safety accidents such as short circuit and leakage caused by moisture entry, ensure the safety of personnel and equipment, and avoid short circuit.

[0027] Working principle: when the device needs to be used, after placing the bottom cover plate 6, the bus duct base sections 1 on both sides are connected, the upper end connecting cover plate 2 is picked up and aligned with the side limit assembly 4, and the four gears 10 connected to the outer wall of the side plate 7 are respectively placed in the limit column 41. Since the rack 42 is meshed with the gear 10, when the gear 10 slides on the rack 42, it drives the internal rotating column 19 to tighten the multiple insulating partitions 11 to a suitable degree. The tightening degree can be observed at the first time through the display knob 8 connected to the rotating column 19. If it is too loose or too tight, it can be observed. When a tight situation occurs, a tightness indicator plate 9 is provided near the display knob 8 to assist the operator to make adjustments. When the connecting side plate 7 is attached to the lower end connecting cover plate 6, a buckle 5 is provided on the outer wall of the side limit assembly 4. At this time, the lever 54 is toggled so that the lever 54 rotates on the inner wall of the fixed column 52 through the rotating shaft 53. The rotation of the lever 54 drives the rotation of the bottom limit screw 58. Since a first sliding rod 59 is provided on the outer wall of the limit screw 58, a first limit groove 510 is opened on the surface of the first sliding rod 59. The first limit groove 510 is engaged with the first sliding rod 59. When the bottom limiting screw 58 drives the circular connecting column 57 to rotate, the slider arranged on the side of the circular connecting column 57 extends out. Since the gear 10 that falls to the bottom is on the same horizontal line as the buckle 5, the extended slider blocks the gear 10, making it impossible for the gear to move on the rack 42, causing the loosening of the equipment components. After the waterproof plates 12 on both sides drive the waterproof cover plate 16 to be pushed toward the center, a fixing component 18 is provided at one end of the waterproof plate 12, and a circular limiting protrusion is provided on the inner wall of the waterproof strip 17. When the pressing column 182 moves to the limiting protrusion When the spring at the other end of the pressing column 182 is stressed and expands, driving the second sliding rod 186 of the outer wall to move in the pressing column 185, so that the connection between the conductor group 13 and the insulating partition 11 is more firmly established. The spring 183 under stress pushes the push rod, so that the spring on the inner wall of the waterproof strip 17 expands and contracts, and the waterproof strip 17 is ejected to the front end of the conductor group 13 to fit it, thereby increasing the waterproof performance. Due to the fixation of the fixing component 18 and the connecting side plate 7, the stability of the conductor group 13 and the insulating partition 11 is further improved, making the connection between the internal components more stable.
