Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, specifically to a modular assembled high-voltage distribution box. Background Technology

[0002] Distribution boxes contain a vast amount of data parameters. They are generally low-voltage circuits constructed according to electrical wiring requirements. They require the assembly of switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in enclosed or semi-enclosed metal cabinets or panels to form a low-voltage distribution box. During normal operation, circuits can be connected or disconnected by manual or automatic switches. Distribution boxes are characterized by their small size, easy installation, special technical performance, fixed location, unique configuration functions, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint, and environmental benefits. The power distribution box is the control center that directs the rational allocation of electrical energy among various components in the power supply line. It is the control link that reliably receives the upstream power supply and correctly feeds back the load electrical energy. It is also the key to obtaining user satisfaction with the power supply quality. Improving the operational reliability of the power distribution box is the goal of creating a high-quality project. Since most of the internal components of traditional distribution boxes are fixed, modular installation cannot be achieved, and different modules cannot be combined, moved, or classified. Therefore, publication number CN112260067A proposes "a modular distribution box". Through the combined use of T-shaped plates, springs, clips, and cardboard, the position of the support plate can be adjusted, which facilitates the combination, movement, and classification of different modules. At the same time, it is convenient for subsequent disassembly and maintenance of different modules.

[0003] However, this solution does not have an automatic fire extinguishing function. If the relevant personnel do not extinguish the fire in time when the equipment catches fire, it will cause a major safety hazard and increase economic losses. In view of the above reasons, this application proposes a modular assembled high-voltage distribution box. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a modular assembled high-voltage distribution box, which solves the problem that the distribution box cannot automatically extinguish fires, posing a significant safety hazard in the event of a fire.

[0014] (III) Beneficial Effects This invention provides a modular assembled high-voltage distribution box. It has the following advantages: 1. By setting up a fire extinguisher, a first push rod motor, a pressure plate, and a vertical pipe, when a fire occurs, the photoelectric smoke detector sends a signal to the central control module. The central control module then simultaneously activates the first push rod motor. The output end of the first push rod motor drives the pressure plate to move down. When the pressure plate moves down, it squeezes the handle on top of the fire extinguisher and drives the two connecting rods on top. When the handle of the fire extinguisher is squeezed, dry powder is sprayed out. The dry powder enters the vertical pipe through the connecting pipe and is finally sprayed out through the through hole on the outside of the vertical pipe, acting on the fire source to achieve the purpose of automatic fire extinguishing.

[0015] 2. By setting up a ventilation box, connecting rods, baffle one, and baffle two, the pressure plate will drive the two connecting rods when it moves down. The connecting rods will drive baffle two, and baffle two will then drive the ventilation hole to move, so that it is offset from the ventilation hole on baffle one. This can prevent outside air from entering the shell, reduce the oxygen content inside the shell, play an auxiliary role in fire extinguishing, and optimize the fire extinguishing effect.

[0016] 3. By setting up a fixed box, a second push rod motor, gears, a gear plate, and an alarm, when a fire is detected, the central control module starts the second push rod motor. The second push rod motor drives the gear plate to move upward, the gear plate then drives the gear, the gear then drives the rotating shaft, and the rotating shaft then drives the second mounting plate. When the conductive block at the bottom of the second mounting plate is in contact with the conductive block at the top of the first mounting plate, the alarm is powered on and sounds an alarm. This allows relevant personnel to be informed of a fire in the distribution box immediately, enabling them to take appropriate measures in a timely manner, reduce economic losses, control the scene, and prevent major safety hazards.

[0017] 4. By setting up pull rod one, clamping plate, spring one, trapezoidal block, horizontal plate, pull rod two, locking block, and spring two, when the fire extinguisher needs to be replaced, first pull rod two is pulled. Pull rod two causes the locking block to separate from the trapezoidal block. Then pull rod one is pulled outward. Pull rod one causes the clamping plate to move. When the clamping plate separates from the fire extinguisher, the fire extinguisher can be taken out. During installation, place the fire extinguisher between the two clamping plates. Then push the two pull rods one towards each other. The two pull rods one then move the two clamping plates and the trapezoidal block. The inclined surface of the trapezoidal block presses against the inclined surface of the locking block. When the inclined surface of the trapezoidal block and the inclined surface of the locking block separate, the locking block is pushed back by spring two and locks onto the trapezoidal block, thus positioning pull rod one. At this time, the inner walls of the two clamping plates are in contact with the fire extinguisher, completing the installation of the fire extinguisher. This not only completes the positioning of the fire extinguisher and ensures the stability of the fire extinguisher during use, but also enables quick replacement and facilitates subsequent maintenance.

The clamping structure 12 not only positions the fire extinguisher 903 and improves the stability of the fire extinguisher 903 during use, but also enables the quick replacement of the fire extinguisher 903, facilitating subsequent maintenance.

[0022] Working principle: The photoelectric smoke detector 7, the central control module 8, the first push rod motor 909, and the second push rod motor 115 are electrically connected. The photoelectric smoke detector 7 is used to monitor whether there is a fire inside the outer casing 1. The central control module 8 can analyze the signal sent by the photoelectric smoke detector 7 and control the first push rod motor 909 and the second push rod motor 115. When the photoelectric smoke detector 7 detects excessive smoke and a fire inside the outer casing 1, it will send a signal to the central control module 8. The central control module 8 will then simultaneously activate the first push rod motor 909 and the second push rod motor 115. The output end of the first push rod motor 909 drives the pressure plate 910 to move down. When the pressure plate 910 moves down, it will squeeze the handle on the top of the fire extinguisher 903 and drive the two connecting rods on the top. 912. When the handle of fire extinguisher 903 is squeezed, dry powder is sprayed out. The dry powder enters the vertical pipe 905 through the connecting pipe 904 and is finally sprayed out through the through hole on the outside of the vertical pipe 905, acting on the fire source to extinguish the fire. The connecting rod 912 drives the second baffle 907, which in turn drives the ventilation hole to move, making it offset from the ventilation hole on the first baffle 906, thereby preventing outside air from entering the outer shell 1, reducing the oxygen content inside the outer shell 1, and playing an auxiliary role in extinguishing the fire. After the second push rod motor 115 is started, it drives the toothed plate 116 to move upward. The toothed plate 116 then drives the gear 114, which in turn drives the rotating shaft 113. The rotating shaft 113 then drives the second mounting plate 119. When the conductive block at the bottom of the second mounting plate 119 is in contact with the... When the conductive block on the top of the first mounting plate 118 is in contact with the electrical box, the alarm 117 is energized and sounds an alarm, enabling relevant personnel to be notified of a fire in the distribution box immediately. This allows them to take appropriate measures to reduce economic losses, control the scene, and prevent major safety hazards. When the dry powder in the fire extinguisher 903 is exhausted and needs to be replaced, first remove the clamp, then separate the connecting pipe 904 from the spray pipe of the fire extinguisher 903. Then pull the two pull rods 127 in opposite directions. The two pull rods 127 then drive the two locking blocks 128, which in turn compress the spring 1210 and drive the sliding rod 129. When the locking block 128 separates from the trapezoidal block 125, pull rod 122 is then pulled outward. 122 drives the clamping plate 123. After the clamping plate 123 separates from the fire extinguisher 903, the fire extinguisher 903 can be removed. During installation, first pull the two levers 122 in a direction away from each other. Lever 122 drives the clamping plate 123. When the space between the two clamping plates 123 is larger than the outer diameter of the fire extinguisher 903, place the fire extinguisher 903 between the two clamping plates 123. Then push the two levers 122 in a direction closer to each other. The two levers 122 then drive the two clamping plates 123 and the trapezoidal block 125. The inclined surface of the trapezoidal block 125 presses against the inclined surface of the locking block 128. When the inclined surface of the trapezoidal block 125 and the inclined surface of the locking block 128 separate, the locking block 128 is pushed back by the second spring 1210 and locks onto the trapezoidal block 125.The pull rod 122 is positioned, at which point the inner walls of the two clamping plates 123 are in contact with the fire extinguisher 903, thus enabling the installation of the fire extinguisher 903.
