[0001] The invention belongs to the technical field of bus ducts, and particularly relates to a plug-in monitoring module structure of a bus duct with a self-checking function. Background Art

[0002] The bus duct plug-in box is a key accessory in the bus duct system and belongs to a device for extending and expanding the branch lines of the bus duct. A molded case circuit breaker is installed inside it. It is connected to the bus duct through pins. The pins are connected to the incoming line end of the circuit breaker, and the electrical equipment is connected to the outgoing line end of the circuit breaker. The circuit breaker is used for circuit breaking and protection, so as to shunt the current of the main line of the bus duct to the electrical equipment; it is widely used in high-rise buildings, industrial plants, commercial complexes, data centers and other places for power distribution between floors, production equipment, shops, server cabinets, etc. It has the advantages of convenient use and maintenance, safety and reliability, etc., and is an efficient and convenient power distribution solution in modern electrical systems;

[0003] However, the connection between the existing bus duct plug-in box and the bus duct does not have the ability of self-checking and protection. When high temperature is generated at the connection, it is easy to cause damage to the connection and reduce its service life. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the invention provides a plug-in monitoring module structure of a bus duct with a self-checking function, which effectively solves the problem that the connection between the existing bus duct plug-in box and the bus duct in the above background art does not have the ability of self-checking and protection, and when high temperature is generated at the connection, it is easy to cause damage to the connection and reduce its service life.

One side of the bus duct body is fixedly installed with an MCU microcontroller. The top of the bus duct body is fixedly installed with a support plate. One side of the support plate is fixedly installed with a driving motor. A plug-in box is arranged below the bus duct body. Rack bars are fixedly installed at the four corners of the plug-in box.

Limit sleeves are fixedly installed on one side of the four slots. The four plug rods are respectively inserted between the four slots and the four limit sleeves. A transmission component is arranged at the output end of the driving motor. The transmission component is in transmission connection with the four rack bars. When the driving motor operates, power is output to the four rack bars through the transmission component, so that the four rack bars drive the plug-in box to move up for plugging or move down to disengage.

[0006] Preferably, fixing frames are provided on one sides of the limiting sleeves away from the busbar trunk body. Moving rods are inserted in the middles of the fixing frames. Slide bars are fixedly installed at both ends of one side of the four fixing frames. Two sliding grooves are respectively formed on the surface of one side of the four limiting sleeves. One ends of the slide bars are respectively slidably installed in the corresponding sliding grooves. A pull rod is fixedly installed between one ends of the two moving rods on the same side.

[0007] Preferably, push discs are fixedly installed at one ends of the moving rods away from the pull rods. Clamping rods are fixedly installed at one ends of the push discs. The four clamping rods are respectively inserted on the four limiting sleeves. Springs are sleeved on the surfaces of the four moving rods. Both ends of the four springs are respectively fixedly connected with the push discs and the fixing frames.

[0008] Preferably, the transmission assembly includes a first sprocket, which is fixedly installed at the output end of the driving motor. A positioning seat is rotatably installed on one side of the first sprocket. The bottom of the positioning seat is fixedly connected with the top of the busbar trunk body. A second sprocket is provided on one side of the first sprocket. A chain is meshed and connected between the second sprocket and the first sprocket.

[0009] Preferably, a shaft rod is fixedly installed in the middle of the second sprocket. Two shaft sleeves are rotatably installed on the surface of the shaft rod. The lower parts of the two shaft sleeves are fixedly connected with the top of the busbar trunk body. Worms are fixedly installed at both ends of the shaft rod. Worms are meshed and connected with worm wheels on the surfaces of the two worms.

[0010] Preferably, rotating shafts are fixedly installed at the bottoms of the worm wheels. The surfaces of the two rotating shafts are respectively rotatably connected with both sides of the busbar trunk body through three bearings. Driving bevel gears are fixedly installed at the bottoms of the two rotating shafts. Driven bevel gears are meshed and connected on one side of the surfaces of the driving bevel gears.

[0011] Preferably, rotating rods are fixedly installed in the middles of the driven bevel gears. Transmission gears are fixedly installed at both ends of the two rotating rods. The four transmission gears are respectively meshed and connected with the four racks. Positioning frames are rotatably installed on one sides of the four transmission gears away from the rotating rods. The tops of the four positioning frames are fixedly connected with the bottom of the busbar trunk body.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) During installation, the operator inserts the upper parts of the four insertion rods on the plug-in box between the four slots and the four limit sleeves respectively, so that the four card holes enter the four limit sleeves and stop. Immediately afterwards, the operator pulls down the four moving rods through the two pull rods. When the four moving rods move down, they all drive the slide bars to slide along the inside of the sliding grooves, increasing the stability of the four moving rods when moving. When the four moving rods move down, they will drive the four clamping rods to move to the bottom. At the same time, during the downward movement of the four clamping rods, due to the extrusion of the four insertion rods, the four clamping rods will move outwards. When the clamping rods move outwards, they all drive the moving rods to move outwards along the middle part of the fixed frame through the pushing disks, and at the same time squeeze the four springs. When the four clamping rods move down to the positions of the four card holes, the four springs push the four clamping rods into the inside of the four card holes through their own elastic force, so as to initially position the plug-in box. At the same time when the initial positioning is completed, the four racks on the plug-in box will also mesh with the four transmission gears;

[0014] Then the operator starts the driving motor to rotate forward. When the driving motor rotates forward, it drives the first sprocket to rotate along the positioning seat. The first sprocket drives the second sprocket to rotate through the chain. The second sprocket drives the shaft rod to rotate inside the two shaft sleeves. When the shaft rod rotates, it drives the two worm wheels to rotate through the two worm gears. When the two worm wheels rotate, they drive the two rotating shafts to rotate in the corresponding bearings. When the two rotating shafts rotate, they both drive the driven bevel gears to rotate through the driving bevel gears. When the two driven bevel gears rotate, they drive the four transmission gears to rotate along the four positioning frames through the two rotating rods. When the four transmission gears rotate, they drive the plug-in box to move up through the four racks. When the plug-in box moves up, it will also insert the male connector into the female connector, and at the same time make the four NTC thermistors close to the female connector, so as to quickly complete the plug-in installation, and at the same time self-check and monitor the temperature at the connection between the plug-in box and the busbar trunk through the four NTC thermistors;

[0015] (2) The four NTC thermistors will transmit the data to the MCU microcontroller in real time during self-check and monitoring. When the MCU microcontroller detects that the temperature at the connection is too high, the MCU microcontroller will start the driving motor to rotate in reverse. When the driving motor rotates in reverse, it will drive the plug-in box to move down through the four racks, so that the male connector on the plug-in box is disconnected from the female connector on the busbar trunk, thus realizing effective protection. And because the clamping rods limit the four insertion rods through the card holes, it is avoided that the plug-in box falls off after being disconnected from the busbar trunk. It enables the connection between this plug-in box and the busbar to have the ability of self-check and protection. When a high temperature occurs at its connection, it can be automatically disconnected, thus realizing effective protection. Description of the Drawings

Detailed embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Example 1, which is given by Figures 1 to 7 Figures 1 to 7 , the present invention includes a busbar trunking body 1, an MCU microcontroller 34 is fixedly installed on one side of the busbar trunking body 1, a support plate 2 is fixedly installed on the top of the busbar trunking body 1, a driving motor 3 is fixedly installed on one side of the support plate 2, a plug-in box 4 is arranged below the busbar trunking body 1, racks 5 are fixedly installed at the four corners of the plug-in box 4, plug rods 6 are fixedly installed at both ends of both sides of the plug-in box 4, clamping holes 7 are formed in the upper parts of the surfaces of the four plug rods 6, a male connector 8 is fixedly installed in the middle of the top of the plug-in box 4, four NTC thermistors 9 are fixedly installed on the upper part of the male connector 8, and a female connector 10 adapted to the male connector 8 is fixedly installed at the bottom of the busbar trunking body 1;

[0028] Two slots 11 are respectively formed on both sides of the busbar trunking body 1, a limiting sleeve 12 is fixedly installed on one side of each of the four slots 11, the four plug rods 6 are respectively inserted between the four slots 11 and the four limiting sleeves 12, a transmission component is arranged at the output end of the driving motor 3, the transmission component is in transmission connection with the four racks 5, and when the driving motor 3 operates, power is output to the four racks 5 through the transmission component, so that the four racks 5 drive the plug-in box 4 to move up for plugging or move down to disengage;

[0029] Fixing frames 30 are arranged on the sides of the limiting sleeves 12 far away from the busbar trunking body 1, moving rods 29 are inserted in the middles of the fixing frames 30, sliding strips 36 are fixedly installed at both ends of one side of the four fixing frames 30, two sliding grooves 35 are respectively formed on the surface of one side of the four limiting sleeves 12, and one ends of the sliding strips 36 are respectively slidably installed in the corresponding sliding grooves 35. Pulling rods 28 are fixedly installed between the ends of the two moving rods 29 on the same side; pushing discs 31 are fixedly installed at the ends of the moving rods 29 far away from the pulling rods 28, clamping rods 32 are fixedly installed at one ends of the pushing discs 31, the four clamping rods 32 are respectively inserted on the four limiting sleeves 12, springs 33 are sleeved on the surfaces of the four moving rods 29, and both ends of the four springs 33 are respectively fixedly connected with the pushing discs 31 and the fixing frames 30.

[0030] During installation, the operator inserts the upper ends of the four insertion rods 6 on the plug-in box 4 between the four slots 11 and the four limit sleeves 12 respectively, so that the four locking holes 7 enter the four limit sleeves 12 and stop; immediately afterwards, the operator pulls the four moving rods 29 downwards through the two pull rods 28. When the four moving rods 29 move downwards, they all drive the slide bars 36 to slide along the inside of the sliding grooves 35, increasing the stability of the four moving rods 29 when moving. When the four moving rods 29 move downwards, they will drive the four locking rods 32 to move to the bottom; at the same time, during the downward movement of the four locking rods 32, due to the extrusion of the four insertion rods 6, the four locking rods 32 will move outwards. When the locking rods 32 move outwards, they all drive the moving rods 29 to move outwards along the middle part of the fixed frame 30 through the pushing discs 31, and at the same time squeeze the four springs 33. When the four locking rods 32 move down to the positions of the four locking holes 7, the four springs 33 push the four locking rods 32 into the inside of the four locking holes 7 through the action of their own elastic force, thereby initially positioning the plug-in box 4. At the same time when the initial positioning is completed, the four racks 5 on the plug-in box 4 will also engage with the transmission component;

[0031] Then the operator starts the driving motor 3 to rotate forward. When the driving motor 3 rotates forward, it drives the transmission component to rotate forward. When the transmission component rotates forward, it drives the plug-in box 4 to move upwards through the four racks 5. When the plug-in box 4 moves upwards, it will also insert the male connector 8 into the female connector 10, and at the same time make the four NTC thermistors 9 close to the female connector 10, so as to quickly complete the plug-in installation, and at the same time self-check and monitor the temperature at the connection between the plug-in box 4 and the busbar body 1 through the four NTC thermistors 9;

[0032] The self-check and monitoring of the four NTC thermistors 9 will transmit the data to the MCU microcontroller 34 in real time. When the MCU microcontroller 34 detects that the temperature at the connection is too high, the MCU microcontroller 34 will start the driving motor 3 to rotate in reverse. When the driving motor 3 rotates in reverse, it will drive the plug-in box 4 to move downwards through the four racks 5, so that the male connector 8 on the plug-in box 4 is disconnected from the female connector 10 on the busbar body 1, thereby realizing effective protection. And because the locking rods 32 limit the four insertion rods 6 through the locking holes 7, it is possible to prevent the plug-in box 4 from falling off after being disconnected from the busbar body 1; enabling the connection between this plug-in box 4 and the busbar to have the ability of self-check and protection. When a high temperature occurs at its connection, it can be automatically disconnected, thereby realizing effective protection.
