Description

Technical Field

[0001] The utility model relates to the technical field of transformer boxes, in particular to a box-type transformer substation with a safety self-locking mechanism. Background Art

[0002] The box-type substation is a factory-prefabricated indoor and outdoor compact distribution equipment that is composed of high-voltage switchgear, distribution transformers and low-voltage distribution devices arranged in one according to a certain wiring scheme. It organically combines the functions of transformer step-down and low-voltage distribution, and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulating, fully enclosed and movable steel structure box.

[0003] Chinese patent publication number CN212626724U discloses a box-type transformer box, including a transformer box, a fan, a triangular drainage top and a heating plate, wherein the transformer box is provided with a waterproof layer, a moisture sensor is installed at the top of the transformer box, and a single-chip microcomputer is installed inside the transformer box on one side of the moisture sensor, a moisture absorption box is installed at the bottom of the transformer box, and a suction port is provided at the top of the moisture absorption box, a transformer body is installed at the top of the moisture absorption box, a fan is installed at the top of the moisture absorption box, the moisture sensor output end is connected to the single-chip microcomputer input end through a wire, and the single-chip microcomputer output end is connected to the fan input end through a wire. The box-type transformer box can discharge the downwardly flowing water through the drainage grooves on both sides through the triangular drainage top, and discharge the water out of the transformer box through the drainage grooves, so that the operator will not get wet when the rain falls when performing maintenance.

[0004] However, when the transformer box is used outdoors, open flames may occur due to various unexpected reasons. When an open flame occurs in the transformer box, firefighters or staff are required to extinguish it, but it is difficult for firefighters or staff to arrive at the scene in the first time, which can easily lead to the expansion of the fire and increase the losses. Utility Model Content

[0005] In response to the above problem, a box-type substation with a safety self-locking mechanism is provided. When an open fire accidentally occurs when the substation box is used outdoors, the fire alarm is used to transmit a signal to the control panel, thereby turning on the air pump to inhale air through the input end of the air pump, and then transmitting the air to the inside of the air cylinder through the output end. At this time, the movable rod will move under the transmission of the air, thereby driving the first U-shaped plug rod away from the socket inside the air partition plate. At this time, the air partition plate will drop to block the heat dissipation holes on the side wall of the partition plate, and the internal space of the substation box will be isolated from the outside world, so that the open fire is extinguished due to lack of oxygen, greatly improving the safety protection effect.

[0006] To solve the problems of the prior art, the utility model provides a box-type substation with a safety self-locking mechanism, comprising a transformer box, a fire alarm is installed on the internal top wall of the transformer box, partitions are symmetrically installed inside the transformer box, and the side walls of the partitions are slidably connected with air baffles, and the side walls of the transformer box and the partitions are provided with a plurality of heat dissipation holes, an air cylinder is installed inside the transformer box through a support ring, a movable rod is movably connected inside the air cylinder, a piston is installed at one end of the movable rod, an L-shaped pull rod is fixedly installed outside the movable rod, a first U-shaped plug rod is fixedly installed outside the L-shaped pull rod through a connecting rod, a socket compatible with the first U-shaped plug rod is provided inside the air baffle, an air pump is fixedly installed on the side wall of the partition, the input end of the air pump is connected with a pipe, and the pipe runs through the partition, the output end of the air pump is connected with a pipe, and one end of the pipe is connected to the air cylinder.

[0007] Preferably, L-shaped support blocks are symmetrically installed on the inner top wall of the transformer box, a dry powder storage box is clamped between the L-shaped support blocks, a closing door is rotatably connected to the outside of the dry powder storage box, and a connecting block with a through hole is installed on the outer wall of the closing door.

[0008] Preferably, one end of the L-shaped pull rod passes through the partition and is fixedly installed with a second U-shaped plug rod, both ends of the second U-shaped plug rod pass through the L-shaped support block and are installed with rollers, and the second U-shaped plug rod is slidably connected to the L-shaped support block.

[0009] Preferably, a cross bar is fixedly installed between the two ends of the second U-shaped plug rod, and a limiting rod adapted to the through hole of the connecting block is fixedly installed on the outside of the cross bar.

[0010] Preferably, air holes are symmetrically provided inside the air cylinder.

[0011] Preferably, the side walls of the air separator are symmetrically provided with sliding blocks, and the side walls of the separator are provided with sliding grooves adapted to the sliding blocks.

[0012] Preferably, the slider is a T-shaped slider.

[0013] Preferably, the partition plate and the air barrier plate are both made of fireproof board.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The fire alarm transmits a signal to the control panel, thereby turning on the air pump and using the input end of the air pump to inhale air, and then transmitting the air to the inside of the air cylinder through the output end. The movable rod will move under the transmission of the air, and the L-shaped pull rod will also move, thereby driving the first U-shaped plug rod away from the socket inside the air partition. The air partition will then drop and block the heat dissipation holes on the side wall of the partition. The internal space of the transformer box is isolated from the outside world, thereby extinguishing the open flame due to lack of oxygen, greatly improving the safety protection effect.

[0016] 2. By moving the L-shaped pull rod, the second U-shaped plug rod will also be driven to move. When the second U-shaped plug rod moves to a certain distance, the roller and limit rod on the second U-shaped plug rod will be out of contact with the closed door on the dry powder storage box. At this time, the closed door will tilt downward and the dry powder will spread out. The dry powder can be used to extinguish the open fire inside the transformer box, reducing losses.

[0027] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] like Figures 1 to 9 As shown, the utility model provides:

[0030] The fire alarm 23 is used to transmit a signal to the control panel, thereby turning on the air pump 11 and using the input end of the air pump 11 to inhale air, and then transmitting the air to the inside of the air cylinder 12 through the output end. The movable rod 13 will move under the transmission of the air, thereby driving the first U-shaped plug rod 7 away from the plug hole inside the air baffle 4. The air baffle 4 will then drop to block the heat dissipation through-holes on the side wall of the baffle 3, and the internal space of the transformer box 1 will be isolated from the outside world, thereby causing the open fire to be extinguished due to lack of oxygen, greatly improving the safety protection effect.

[0031] like Figure 3 As shown, the inner top wall of the transformer box 1 is symmetrically mounted with L-shaped support blocks 5, a dry powder storage box 6 is clamped between the L-shaped support blocks 5, the outer portion of the dry powder storage box 6 is rotatably connected to a closing door 18, and the outer wall of the closing door 18 is mounted with a connecting block 20 with a through hole.

[0034] By moving the L-shaped pull rod 9, the second U-shaped plug rod 14 will also be driven to move. When the second U-shaped plug rod 14 moves to a certain distance, the roller 21 and the limit rod 22 on the second U-shaped plug rod 14 will be out of contact with the closing door 18 on the dry powder storage box 6.
