Description

Technical Field

[0001] The invention belongs to the technical field of bus ducts, and particularly relates to a bus duct fire prevention warning system. Background Art

[0002] The fire prevention warning bus duct is a bus duct system integrated with a fire prevention warning function, which is a combination of bus duct technology and fire safety technology; it not only has the function of efficiently transmitting electric energy of a traditional bus duct, but also can, through the built-in fire prevention monitoring device, monitor the operation state of the bus duct in real time, discover fire hazards in time, and ensure the safety and reliability of the power system; the shell and insulating material of the bus duct usually adopt high-temperature resistant, flame retardant or fireproof materials, such as fireproof mica tape, fireproof insulating paint, etc., which can delay the spread of fire in case of a fire and gain time for personnel evacuation and fire fighting; among them, monitoring devices such as integrated temperature sensors and smoke detectors can monitor parameters such as the temperature and smoke concentration inside the bus duct in real time; when an abnormality is detected, the system will immediately issue an alarm and transmit the data to the fire control center or monitoring platform through a communication interface for timely measures to be taken.

[0003] The positions of the detectors in the existing bus duct fire prevention warning system are fixed, and the structure of the bus duct is long, resulting in the detectors being unable to quickly collect information inside the bus duct in time, there are detection dead angles, and its use effect is not good. Summary of the Invention

A transmission component is provided at the output end of the driving motor. The transmission component is in transmission connection with the temperature detector and the smoke detector. When the driving motor operates, power is output to the temperature detector and the smoke detector through the transmission component, so that the temperature detector and the smoke detector reciprocally move along the inside of the bus duct body.

[0006] Preferably, the transmission assembly includes an upper gear fixedly installed at the output end of the driving motor. A positioning frame is rotatably installed on one side of the upper gear, and the bottom of the positioning frame is fixedly connected to the top of the busbar trunking body. The lower part of the upper gear is meshed with a lower gear, a rotating rod is fixedly installed in the middle of the lower gear, and two rotating sleeves are rotatably installed on the surface of the rotating rod. The bottoms of the two rotating sleeves are both fixedly connected to the top of the busbar trunking body through fixed heads.

[0007] Preferably, active bevel gears are fixedly installed at both ends of the rotating rod. Driven bevel gears are fixedly installed on one side of the surfaces of the active bevel gears. Positioning seats are rotatably installed on the mutually remote sides of the two active bevel gears. The bottoms of the two positioning seats are both fixedly connected to the top of the busbar trunking body. Shaft rods are fixedly installed on one side of the two driven bevel gears. Bushings are rotatably installed on the surfaces of the two shaft rods. The bottoms of the two bushings are both fixedly connected to the top of the busbar trunking body through fixed seats.

[0008] Preferably, upper sprockets are fixedly installed at the ends of the shaft rods away from the driven bevel gears. Lower sprockets are provided below the two upper sprockets, and chains are meshed between the two lower sprockets and the two upper sprockets.

[0009] Preferably, rotating shafts are fixedly installed on one side of the lower sprockets. The surfaces of the two rotating shafts are rotatably connected to one ends of the two mounting boxes through bearings. One ends of the two rotating shafts respectively extend into the interiors of the two mounting boxes and are both fixedly installed with reciprocating lead screws. One ends of the two reciprocating lead screws are both rotatably connected to the inner walls of the other ends of the two mounting boxes through shaft seats.

[0010] Preferably, reciprocating nuts are threadedly connected to the surfaces of the reciprocating lead screws. On the mutually close sides of the two reciprocating nuts, two sliding sleeves are respectively fixedly installed through two connecting rods. Slide bars are inserted into the interiors of the four sliding sleeves. Connecting frames are fixedly installed between the bottoms of the adjacent two slide bars. The tops of the two connecting frames are respectively fixedly connected to the bottoms of the two reciprocating nuts. Springs are sleeved on the upper and lower parts of the surfaces of the four slide bars. The two ends of the eight springs are respectively fixedly connected to the slide bars and the sliding sleeves. Support bars are fixedly installed between the adjacent two sliding sleeves.

[0011] Preferably, transmission pins are fixedly installed on the mutually close sides of the two support bars. Partition plates are fixedly installed in the interiors of the two mounting boxes. Limiting grooves are opened on the surfaces of the two partition plates. The two transmission pins are respectively inserted into the interiors of the two limiting grooves. The mutually close ends of the two transmission pins are respectively fixedly connected to a temperature detector and a smoke detector.

[0012] Preferably, sliders are fixedly installed on the mutually remote sides of the two reciprocating nuts. Chute grooves are opened on the inner walls of the two mounting boxes. The two sliders are slidably installed in the interiors of the two chute grooves.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] (1) During operation, the operator starts the driving motor to drive the upper gear to rotate along the positioning frame. When the upper gear rotates, it drives the rotating rod to rotate inside the two rotating sleeves through the lower gear. When the rotating rod rotates, it drives the two driven bevel gears to rotate through the two driving bevel gears. The two driven bevel gears drive the two shaft rods to rotate inside the two shaft sleeves. When the two shaft rods rotate, they drive the two upper sprockets to rotate. When the two upper sprockets rotate, they drive the two lower sprockets to rotate through the two chains. When the two lower sprockets rotate, they drive the two rotating shafts to rotate inside the two bearings. When the two rotating shafts rotate, they drive the two reciprocating lead screws to rotate along the two shaft seats;

[0015] (2) When the two reciprocating lead screws rotate, they drive the two reciprocating nuts to reciprocate. When the reciprocating nuts move, they both drive the sliders to slide inside the chutes, improving the stability of the two reciprocating nuts during movement. When the two reciprocating nuts move, they both drive the four sliding sleeves to move through the connecting rods. When the four sliding sleeves move, they drive the transmission pins to move through the two support bars. When the transmission pins move, they drive the temperature detectors and smoke detectors to reciprocate. While the transmission pins are moving, they will move along the limiting grooves on the partition board. Thus, during the reciprocating translation of the transmission pins, they can move up and down along the trajectory of the limiting grooves. When the transmission pins move, they drive the sliding sleeves to slide up and down along the surface of the sliding rods through the support bars, and at the same time squeeze the corresponding springs. Thus, while ensuring the stability of the movement of the transmission pins, it has the effect of elastic reset, and further enables the temperature detectors and smoke detectors to effectively monitor the inside of the busbar trunking body in all directions. At the same time, the temperature detectors and smoke detectors will transmit data to the external monitoring platform in real time through the wireless LoRa method to notify the management personnel;

[0016] (3) It enables the detectors of the busbar trunking fire warning system of the present invention to move, ensuring rapid collection of information inside the busbar trunking, without detection dead angles, and improving the use effect. BRIEF DESCRIPTION OF THE DRAWINGS
