Description

Technical Field

[0001] The invention relates to the field of bus duct connection, and in particular to a bus duct capable of slidably taking in electricity. Background Art

[0002] With the emergence of modern engineering facilities and equipment, the electricity consumption of various industries has increased rapidly, especially with the emergence of numerous high-rise buildings and large factories and workshops. Bus ducts have emerged as a new type of power distribution conductor. Different types of bus ducts have different working methods and functions, including sliding power bus ducts. Sliding power bus ducts allow power to be taken at different positions of the bus without the need for complex adjustments or changes to the entire system. This design is particularly suitable for occasions where frequent changes in power supply points are required or where flexible adjustments to power distribution are required;

[0003] However, when the sliding power bus duct is actually installed, its end is generally a plurality of copper plates or aluminum plates for conducting electricity. However, the copper plates at the ends of the bus duct are generally fixed. When two bus ducts are connected, in order to ensure that the two copper plates are staggered in contact, the installation requirements of the bus duct are relatively high. The connection direction of the bus duct needs to be deliberately controlled to complete the matching connection of the copper plates on the two bus ducts. However, this installation method is relatively cumbersome and requires high operation.

[0004] Therefore, it is necessary to propose a bus duct with slidable power supply to solve the above problems. Summary of the invention

Two abutting blocks are symmetrically fixed on both ends of the insulating sleeve, and the abutting blocks are arranged in an isosceles trapezoid. The outer side of the abutting block is clamped on the inner side of the two corresponding inclined surfaces.

[0010] Preferably, two groups of busbars are fixedly provided on the inner side of the wire trough shell, and a plurality of sliding connection plates for connecting the two groups of busbars are movably provided on the inner side of the wire trough shell, and a plurality of contact grooves are provided on the outer sides of the sliding connection plates and the busbars, and the sliding connection plates and the busbars are connected through the contact grooves.

[0011] Preferably, insulating plates are fixedly provided at both ends of the sliding power connection plate, a plurality of guide rods are fixedly provided at the upper and lower ends of the insulating plates, a plurality of special-shaped grooves are opened on the inner side of the wire trough shell, the guide rods slide on the inner side of the special-shaped grooves, and a plurality of lifting blocks are fixedly provided on the outer side of one group of the busbars, and the lifting blocks are arranged in a right-angle trapezoidal shape.

[0014] Preferably, a baffle is fixedly provided at one end of the wire trough housing, and a connecting sleeve is provided at the ends of two wire trough housings connected by bolts;

[0015] A plurality of insulating blocks are fixedly provided at the end of the wire trough shell, and one end of the insulating block is fixedly connected to one end of the corresponding guide shell.

[0016] Preferably, a side of the clamping block close to the abutting block is provided with a rounded corner.

[0018] Preferably, a current sensor and a temperature sensor are installed on the inner wall of the connecting sleeve, and both the current sensor and the temperature sensor are connected to the electric telescopic rod through a controller.

[0019] Technical effects and advantages of the present invention:

[0020] 1. The insulating sleeve is slidably arranged on the inner side of the guide shell, so when installing the two wire trough shells, there is no need to consider the installation method of the conductive plate. You only need to directly install the wire trough shell. The operation is simple. When the two conductive plates are in contact, the conical surface is set, and then the conductive plates on both sides automatically give way and are staggered and fitted;

[0021] 2. When two conductive plates are connected, the mutual moving distance of the two conductive plates causes the abutment block to enter between the two clamping blocks, and the conductive plates are fixed by the shape setting of the abutment block. By setting the arc plate, the conductive plates are fixed to where they move, so as to ensure the fixation of the conductive plates, prevent the conductive plates from being irreversibly loosened by the outside world, and cause gaps, resulting in circuit disconnection. While the conductive plates are automatically installed, the safe use of the conductive plates is simultaneously ensured;

[0022] 3. Through the setting of the sliding connection board, the corresponding bus duct can be manually controlled to cut off the power. When one of the bus ducts fails, it can be specifically cut off to reduce the scope of power outage and the scope of power outage when repairing the bus duct. The sliding connection board is used to slide and control the circuit connection of the bus;

[0023] 4. By setting the fitting groove, when the conductive plates abut each other, the fitting strength between the two conductive plates can be increased by the cooperation of the fitting groove and the conical surface. By setting the fitting groove, the contact area of ​​the two conductive plates is increased, thereby increasing the connection strength.

[0024] 5. The contact area between the two conductive plates is enlarged by setting the bonding groove, and the cross-sectional area is increased to reduce resistance and improve the conductivity of the contact point when current is transmitted. A larger contact area means that more electrons can flow smoothly from one conductive plate to another, reducing the resistance caused by electron accumulation or lack at the contact point.

[0025] 6. By setting the lifting block, when the sliding contact plate moves, the side of the sliding contact plate that originally contacts the busbar is completely separated from the busbar, thereby preventing the conductive metal from generating galvanic corrosion during the separation of the sliding contact plate and the busbar. The conductors do not contact each other, and the conditions for electrochemical corrosion will not be formed between them. Therefore, galvanic corrosion is not easy to occur, thereby increasing the service life of the sliding contact plate and the busbar. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] 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.

[0041] The present invention provides Figure 1 - Fig.13A slidable bus duct for power supply shown in the figure includes a duct shell 2. Two or more duct shells 2 are spliced ​​to form a duct group 1. A baffle 201 is fixedly provided at one end of the duct shell 2. The baffle 201 is used to protect the copper plate for transmitting electricity. The ends of the two duct shells 2 are bolted together to provide a connecting sleeve 3. The connecting sleeve 3 is used to seal the connection between the two duct shells 2, to strengthen the connection between the two duct shells 2, and to seal the duct shells 2. The connecting sleeve 3 is a prior art and will not be described in detail here.

[0042] Multiple conductive plates 401 are movably provided at both ends of the wire trough housing 2, wherein the conductive plates 401 are generally copper plates or aluminum plates as conductors to transmit power. The conductive plates 401 are prior art and will not be described in detail here. Two guide shells 5 are provided at both ends of the wire trough housing 2.

[0043] A rectangular groove 6 is formed through one end of the guide shell 5, and an insulating sleeve 7 is movably provided inside the rectangular groove 6. One end of the conductive plate 401 is fixedly connected to one end of the corresponding insulating sleeve 7. The guide shell 5 is made of the same material as the insulating sleeve 7 to ensure insulation during current conduction.

[0044] Two guide blocks 9 are fixedly provided at both ends of the insulating sleeve 7, a guide groove 8 is penetrated through one end of the guide shell 5, and the guide block 9 slides on the inner side of the corresponding guide groove 8. The cross-sections of the guide groove 8 and the guide block 9 are rectangular. A conical surface 18 is provided at the end of the conductive plate 401 away from the busbar 4. The shape of the guide groove 8 and the guide block 9 is set to ensure the moving direction of the guide block 9.

[0045] The insulating sleeve 7 is slidably arranged on the inner side of the guide shell 5, and when installing the two wire trough shells 2, there is no need to consider the installation method of the conductive plate 401, and the wire trough shells 2 only need to be directly installed. The operation is simple. When the two conductive plates 401 are in contact, the conical surface 18 is set, and then the conductive plates 401 on both sides automatically give way and are staggered and fitted;

[0046] A plurality of clamping blocks 10 are symmetrically fixed on the inner side of the rectangular groove 6, and a corresponding end of the clamping block 10 is provided with a slope 11. Two abutting blocks 13 are symmetrically fixed on both ends of the insulating sleeve 7, and one end of the clamping block 10 corresponding to the abutting block 13 is provided with two arc-shaped grooves 12. The abutting block 13 is arranged in an isosceles trapezoid, and the outer side of the abutting block 13 is clamped on the inner side of the two corresponding slopes 11.

[0047] When the two conductive plates 401 are connected, the mutual movement distance of the two conductive plates 401 causes the abutment block 13 to enter between the two clamping blocks 10, and the conductive plates 401 are fixed by the shape setting of the abutment block 13. By setting the arc plate 14, the conductive plates 401 are fixed to the places where they move, so as to ensure the fixation of the conductive plates 401 and prevent the conductive plates 401 from loosening and generating gaps, resulting in circuit disconnection. While the conductive plates 401 are automatically installed, the safe use of the conductive plates 401 is simultaneously ensured.

[0048] A plurality of arc-shaped plates 14 are fixedly disposed on the outer side of the abutting block 13 , and the arc-shaped plates 14 are clamped on the inner sides of the corresponding arc-shaped grooves 12 .

[0049] When the arc-shaped plate 14 is clamped in the arc-shaped groove 12 , the position of the conductive plate 401 is completely fixed, and the moving range of the insulating sleeve 7 is greater than the thickness of a single conductive plate 401 .

[0050] Two sets of busbars 4 are fixedly provided inside the wire trough shell 2, and a plurality of sliding connection plates 402 for connecting the two sets of busbars 4 are movably provided inside the wire trough shell 2. The material of the sliding connection plates 402 is the same as that of the busbars 4 to prevent the conductive material from forming a spontaneous battery, which causes the more active metal to act as an anode and corrode.

[0051] A plurality of contact grooves 403 are provided on the outer sides of the sliding contact plate 402 and the busbar 4. The sliding contact plate 402 and the busbar 4 are connected through the contact grooves 403. The contact grooves 403 are provided to increase the contact area and reduce the resistance.

[0052] Both ends of the sliding connection plate 402 are fixed with insulating plates 404, and multiple guide rods 405 are fixedly provided at the upper and lower ends of the insulating plate 404. A plurality of special-shaped grooves 406 are opened on the inner side of the wire trough housing 2. The two ends of the special-shaped grooves 406 are arranged in parallel and the middle is inclined. The guide rods 405 slide on the inner side of the special-shaped grooves 406. A plurality of lifting blocks 407 are fixedly provided on the outer side of one group of busbars 4. The lifting blocks 407 are made of rubber insulating material, which is a commonly used material for existing insulators and is a prior art, so no further description is given here.

[0053] The lifting block 407 is arranged in a right-angle trapezoidal shape. Two electric telescopic rods 409 are fixedly provided inside the wire trough housing 2. A connecting plate 408 is fixedly provided at the output end of the electric telescopic rod 409. One end of the connecting plate 408 is fixedly connected to one end of the corresponding insulating plate 404.

[0054] By setting the sliding power board 402, the corresponding bus duct can be manually controlled to cut off power, and when one of the bus ducts fails, it can be specifically cut off from power, reducing the scope of the power outage and reducing the scope of the power outage when repairing the bus duct.

[0055] A current sensor 301 and a temperature sensor 302 are installed on the inner wall of the connecting sleeve 3. The current sensor 301 and the temperature sensor 302 are connected to the electric telescopic rod 409 through a controller. The controller is a prior art and will not be described in detail here.

[0056] A current sensor 301 for monitoring the current of the busbar 4 is provided on the inner wall of the connecting sleeve 3. The current sensor 301 is connected to the electric telescopic rod 409 through a controller to set a safety threshold of the current passing through the busbar 4. When the current sensor 301 detects that the current passing through the busbar 4 exceeds its safety threshold, the electric telescopic rod 409 is started by the controller, so that the electric telescopic rod 409 drives the insulating plate 404 to move, and then the insulating plate 404 drives the sliding power connection plate 402 to move, so that the sliding power connection plate 402 disconnects the circuit connection of the two corresponding busbars 4, thereby achieving the purpose of power off and avoiding overall damage to the busbar 4.

[0057] In the present invention, a temperature sensor 302 is also provided on the inner wall of the connecting sleeve 3, and the temperature sensor 302 is also connected to the electric telescopic rod 409 through a controller to set a safety threshold of the temperature during use of the busbar 4. When the temperature sensor 302 detects that the temperature near the busbar 4 exceeds its safety threshold, the controller controls the electric telescopic rod 409 to start, so that the electric telescopic rod 409 drives the insulating plate 404 to move, and then the insulating plate 404 drives the sliding power board 402 to move, so that the sliding power board 402 disconnects the circuit connection of the two corresponding busbars 4, thereby achieving the purpose of power off, avoiding overall damage to the busbar 4, and realizing the purpose of automatically monitoring faults and stopping losses in time.

[0058] By setting the lifting block 407, when the sliding contact plate 402 moves, the side of the sliding contact plate 402 that originally contacts the busbar 4 is completely separated from the busbar 4, thereby preventing the conductive metal from generating galvanic corrosion during the separation of the sliding contact plate 402 and the busbar 4. The conductors do not contact each other, and the conditions for electrochemical corrosion are not formed between them. Therefore, galvanic corrosion is not likely to occur, thereby increasing the service life of the sliding contact plate 402 and the busbar 4.

[0059] A plurality of fitting grooves 19 are symmetrically provided at both ends of the conductive plate 401. Through the provision of the fitting grooves 19, when the conductive plates 401 abut against each other, the fitting strength between the two conductive plates 401 can be increased through the cooperation of the fitting grooves 19 and the conical surface 18. Through the provision of the fitting grooves 19, the contact area of ​​the two conductive plates 401 is increased, thereby increasing the connection strength.

[0060] Furthermore, by providing the fitting groove 19, the contact area between the two conductive plates 401 is enlarged, thereby increasing the cross-sectional area thereof when current is transmitted, thereby reducing resistance and improving the conductivity of the contact point. A larger contact area means that more electrons can flow smoothly from one conductive plate 401 to another conductive plate 401, thereby reducing resistance caused by electron accumulation or lack at the contact point.

[0061] An installation opening 21 is provided on the inner side of the fitting groove 19 away from the busbar 4 to ensure the mutual connection of the conductive plates 401 and prevent the two conductive plates 401 from abutting against each other, resulting in connection failure.

[0062] A rounded corner 101 is formed on one side of the clamping block 10 close to the abutting block 13 . The rounded corner 101 facilitates the arc-shaped plate 14 to enter the inner side of the arc-shaped groove 12 .

[0063] The arc plate 14 and the abutment block 13 are both made of elastic insulating rubber material, and the rubber material can prevent the electron transmission line from bifurcating too much, which would lead to a large resistance.

[0064] A plurality of insulating blocks 20 are fixedly disposed at the end of the wire trough housing 2 , wherein the insulating blocks 20 are made of conventional rubber insulating material and will not be described in detail herein. One end of the insulating block 20 is fixedly connected to one end of the corresponding guide housing 5 .

[0065] Working principle: The operator connects two wire trough shells 2, first fixes one of the wire trough shells 2, and then installs the second wire trough shell 2 after the fixation is completed, aligns the second wire trough shell 2 with one end of the first wire trough shell 2, ensures that the first wire trough shell 2 and the second wire trough shell 2 are in the same horizontal plane, and then directly connects them, so that the second wire trough shell 2 drives the insulating block 20 to move, and then the insulating block 20 drives the guide shell 5 to move, and then the guide shell 5 drives the insulating sleeve 7 to move, and then the insulating sleeve 7 drives the corresponding conductive plate 401 to move, so that the ends of the two sets of conductive plates 401 contact each other, The conical surface 18 is set so that the two conductive plates 401 are pushed by thrust, and the conductive plates 401 are staggered by their own elasticity, so that the conductive plates 401 drive the abutment blocks 13 to move, and the guide blocks 9 slide in the guide grooves 8, so that the conductive plates 401 can only move in parallel, so that the abutment blocks 13 move toward between the two corresponding clamping blocks 10, and the abutment blocks 13 drive the arc plate 14 to contact the inclined surface 11 of the clamping block 10, until the sliding plate enters the arc groove 12, so that the abutment blocks 13 are fixed, and the position of the conductive plates 401 is fixed to prevent them from shaking due to external factors;

[0066] When the conductive plates 401 are in contact with each other, the two conductive plates 401 are in contact with each other through the installation opening 21. The connection directions of the two conductive plates 401 are opposite, so that the fitting grooves 19 thereof are staggered with each other. Figure 5 As shown, the conductive plate 401 is installed, and then the connecting sleeve 3 is installed to complete the installation of the wire trough group 1;

[0067] When a short circuit occurs in one of the busbars 4, it is necessary to cut off the power supply. The operator controls the corresponding electric telescopic rod 409 by controlling the switch to drive the connecting plate 408 to work, so that the connecting plate 408 drives multiple insulating plates 404 to move at the same time. The insulating plates 404 slide in the special-shaped grooves 406 through the setting of the conductor rods through the guide rods 405 to limit the moving direction of the insulating plates 404, so that the insulating plates 404 drive the sliding power connection plate 402 to move, so that the sliding power connection plate 402 is separated from one of the busbars 4, so as to complete the circuit disconnection control, and then the busbar 4 that needs to be repaired is repaired;

[0068] When the sliding connection plate 402 moves, the lifting block 407 is provided to make the sliding connection plate 402 squeeze the busbar 4 to fix and support the end of the busbar 4;

[0069] After the maintenance is completed, the electric telescopic rod 409 is controlled to drive the insulating plate 404 to reset and slide to connect the circuit. The corners of the contact groove 403 on the busbar 4 are provided with an oblique angle to facilitate the sliding of the sliding connection plate 402.
