Description

Technical Field

[0001] The invention relates to the technical field of urban integrated corridor power distribution equipment, in particular to high-performance and safe urban integrated corridor power distribution equipment. Background Art

[0002] Corridor means a covered aisle, the horizontal traffic space of a building. During urban construction, for large buildings or park attractions, urban integrated corridors will be built accordingly according to design requirements. In order to ensure normal electricity consumption within the urban integrated corridors, power distribution equipment needs to be installed.

[0003] However, most of the existing power distribution equipment is a fixed cabinet equipment with a single wiring power supply during use. When the power distribution equipment is used for a long time or the current and voltage passing through it are too large, it is easy to cause internal circuits to heat up, thereby increasing the probability of causing a fire. In addition, for the heat dissipation of the power distribution equipment, most of the heat dissipation methods use simple cooling fans, and when a fire occurs, manual measures are taken to extinguish the fire of the power distribution equipment. It is impossible to evenly ventilate and dissipate the heat inside the power distribution equipment according to the actual situation on site of the power distribution equipment. When a fire occurs, dry powder fire extinguishing agent cannot be immediately and evenly sprayed to extinguish the fire in the power distribution equipment in time. At the same time, the alarm light cannot be popped up in the first time, which directly reduces the operating performance and safety performance of the power distribution equipment and poses a threat to the personal safety of people passing through the urban integrated corridor. When the power distribution equipment fails and is damaged and needs to be repaired, due to the large number of internal circuits of the power distribution equipment, the power distribution equipment components cannot be spatially expanded and adjusted to provide sufficient maintenance space for maintenance personnel. For this reason, high-performance and safe urban integrated corridor power distribution equipment is proposed. Summary of the invention

[0036] Working principle: when the internal components of the power distribution cabinet 1 fail or are damaged and need to be repaired, first open the door of the power distribution cabinet 1, and the electric push rod 52 drives the limit slide 53 to push downward in the limit slide groove 51, and the limit slide 53 drives the two push-pull rods 54 to expand and extend to the front side synchronously. As the outward expansion length of the two push-pull rods 54 gradually increases, the two push-pull rods 54 drive the first mounting frame 2 to move forward through the second mounting frame 3. At the same time, the first mounting frame 2 and the second mounting frame 3 synchronously drive the supporting protrusion 16 and slide forward in the supporting slide rail 15. When the second mounting frame 3 moves forward to the door position of the power distribution cabinet 1, the maintenance personnel manually press the second mounting frame 3 to limit the position, and then drive the first mounting frame 2 to continue to move forward, so that the first mounting frame 2 drives the auxiliary wheel 12 to continue to roll forward in the auxiliary guide rail 13, and wait for the first mounting frame 2 to move forward. After the support boss 16 and the auxiliary wheel 12 on the mounting frame 2 successively slide out of the travel range of the support slide rail 15 and the auxiliary guide rail 13, due to the height difference between the first mounting frame 2 and the ground, the support spring 10 in the fixed cylinder 9 drives the T-shaped slide 11 to move downward, and the T-shaped slide 11 then drives the suspended auxiliary wheel 12 downward to contact the ground surface, providing movement compensation for the first mounting frame 2. As the first mounting frame 2 gradually moves outward and forward, the two groups of connecting rods 57 contract inward and drive the two groups of auxiliary sliding blocks 56 to slide inward in the two groups of auxiliary slide grooves 55, providing extended travel compensation for the first mounting frame 2 and the second mounting frame 3, thereby expanding the distance between the first mounting frame 2 and the second mounting frame 3, providing sufficient working space for maintenance personnel, and then the maintenance personnel use tools to inspect and repair the internal components of the power distribution cabinet 1;

[0037] The current and voltage sensor 62 senses and monitors the current and voltage of the internal circuit of the distribution cabinet 1 in real time. If the current and voltage of the internal circuit of the distribution cabinet 1 are too large and overloaded, the magnetic saturation relay 61 quickly cuts off the power to the entire circuit of the distribution cabinet 1. At this time, the electromagnet 66 in the power-off state loses its adsorption magnetic force, and the elastic rope 68 in the stretched state elastically resets and forces the auxiliary magnet 67 to move downward. The auxiliary magnet 67 in the rapidly downward moving state drives one side of the adjusting rod 69 to move downward rapidly. According to the seesaw principle, the other side of the adjusting rod 69 tilts upward and drives the auxiliary slide 64 to The auxiliary slide rail 63 slides upward quickly, so that the auxiliary slide seat 64 drives the three-color alarm light 65 to bounce up quickly, and the cover plate is bounced outward until the three-color alarm light 65 bounces to a predetermined height. At this time, the length of the elastic rope 68 is restored to within the initial elastic stroke, and the elastic rope 68 provides a stable traction force to the three-color alarm light 65 through the auxiliary magnet 67 and the adjustment rod 69. At the same time, the popped-up three-color alarm light 65 flashes the alarm light to warn the passers-by and staff in the urban integrated corridor, and then the staff notifies the power supply unit to quickly arrive at the scene to inspect and repair the power distribution cabinet 1;

[0038] When the power distribution cabinet 1 is working normally, the second solenoid valve 88 is closed to block the passage of the dry powder storage tank 87 into the four-way joint 83, and the first solenoid valve 86 is opened, and the small refrigerator 85 cools the air entering the suction head 84, and then the booster pump 82 supplies cold air into the four-way joint 83. The cold air is evenly divided into two paths through the three-way joint 89 and enters the two branch pipes 810 synchronously. Then the cold air passes through two groups of main pipes 811 and is evenly sprayed to the internal space of the power distribution cabinet 1 by two groups of nozzles 812, so as to evenly cool and dissipate the heat of the internal environment of the power distribution cabinet 1. When an open flame occurs in the power distribution cabinet 1, the open flame sensor 81 first senses and collects the open flame. At the same time, the first solenoid valve 86 is closed to block the air from entering the suction head 84. The channel of the four-way joint 83, the second solenoid valve 88 is opened, and then the booster pump 82 supplies the dry powder fire extinguishing agent in the dry powder storage tank 87 into the four-way joint 83. Similarly, the dry powder fire extinguishing agent is evenly divided into two ways through the three-way joint 89 and synchronously enters the two branch pipes 810. Then the dry powder fire extinguishing agent passes through two groups of main pipes 811 and is evenly sprayed into the internal space of the distribution cabinet 1 by two groups of nozzles 812. The dry powder fire extinguishing agent extinguishes the open fire inside the distribution cabinet 1. At the same time, the magnetic saturation relay 61 quickly cuts off the power to the line. Similarly, the three-color alarm light 65 that pops up flashes the alarm light to warn the passers-by and staff in the urban integrated corridor, and then the staff immediately takes corresponding fire extinguishing measures for the distribution cabinet 1 and calls the fire number.
