Abstract

The present application discloses an electric cabinet capable of internal fire extinguishing and a method for using the same. When a fire occurs in the electric cabinet during use, the pull ring can be pulled first. After the pull ring is pulled down, the triangular seat can be driven to push the horizontal plate outwards. The horizontal plate can drive the inner rod away from the baffle door. When the inner rods on both sides are away from the baffle door, the baffle door can be quickly opened. After the baffle door is opened, the sand in the sandbox can be put into the cabinet, thereby covering the equipment in the cabinet and isolating it from oxygen. During the opening process of the baffle door, the baffle door opens to both sides under the impact of the sand. During the opening process, the baffle door will push up the vertical frame, and the vertical frame can drive the blocking plate to rotate toward the heat dissipation port, thereby blocking the heat dissipation port, and oxygen will not enter the cabinet. Through the arrangement, the equipment in the cabinet can reduce the contact with oxygen, thereby achieving rapid fire extinguishing, thereby improving the fire extinguishing efficiency.

Description

Technical Field

[0001] The present application relates to the technical field of power cabinets, and in particular to a power cabinet capable of internal fire extinguishing and a method of using the same. Background Art

[0002] The power cabinet (box) is divided into power cabinet (box), lighting cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The power cabinet is a general term for the motor control center. The power cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] The power cabinet is a device for centralized control of the power system. The power cabinet is usually placed outdoors for use. The power cabinet relies on its own cooling system to simply dissipate heat inside the equipment. However, the temperature inside the power cabinet will be higher in hot weather. The surge in electricity consumption in summer will cause the equipment inside the power cabinet to overheat, causing a fire. In the event of a fire, it is necessary to open the cabinet door to extinguish the fire. However, the outer body of the power cabinet is made of metal, so it is difficult to open the door in time to extinguish the fire, which results in the power cabinet being unable to be operated to extinguish the fire in time, resulting in property loss.

[0014] To achieve the above purpose, another technical solution adopted by the present application is: a method for using an internal fire extinguishing power cabinet, comprising the following steps:

[0015] S1: First, inject sand into the sandbox for pre-storage. If a fire occurs inside the cabinet, the pull ring can be immediately pulled. The pull ring is located inside the side box. The personnel can quickly pull the pull ring inside the side box. When the pull ring is pulled down, the pull ring will drive the triangular seat to move downward. When the triangular seat moves downward, it will push the horizontal plate, and the horizontal plate will move away from the cabinet. The sliding rod connected to the horizontal plate will extend to the outside of the cabinet. When the sliding rod extends, it will pull the inner rod away from the blocking door;

[0016] S2: When the inner rod on one side of the door is moved away, one side of the door will not be restricted by the inner rod. As the inner rod on one side moves away, the inner rod will drive the first connecting rod to move, and the first connecting rod will drive the swing rod to move to one side through the bracket. When the bracket pulls the swing rod to move, the swing rods on both sides will move to the middle of the horizontal groove of the second connecting rod. When the swing rods on both sides touch each other, the swing rods cannot move in the horizontal groove.

[0017] S3: When the bracket continues to move with the first connecting rod, the swing rod on the bracket will rotate in the direction of the second connecting rod, and the swing rod will push the second connecting rod in the opposite direction. The second connecting rod will move away from the door position under the push of the swing rod, and the inner rod on the other side will move away from the door. The door will open after it is not restricted by the inner rod, and the sand will fall quickly and adhere to the internal equipment to reduce its contact with oxygen to achieve fire extinguishing. When the door is opened, it will rotate, and the top frame on the door will push the vertical frame. When the vertical frame moves up, it will drive the blocking plate to rotate toward the heat dissipation port. When the blocking plate is parallel to the heat dissipation port, the heat dissipation port will be blocked by the blocking plate, and the external air will no longer enter the power cabinet, and the amount of oxygen inside the power cabinet can be reduced.

[0018] Compared with the prior art, the beneficial effects of this application are:

[0019] The invention discloses an electric power cabinet capable of internal fire extinguishing and a method for using the same. A sand box is arranged on the electric power cabinet, and sand can be placed in advance inside the sand box. A side box is arranged on the cabinet body, and a pull ring can be installed inside the side box. The pull ring can control the placement of sand. When a fire occurs inside the electric power cabinet, the pull ring can be pulled downward, and the pull ring will drive the triangular seat to move downward. When the triangular seat moves downward, the cross plate will be pushed up at the same time, and the cross plate will move outward, thereby moving away from the cabinet body. When the cross plate moves outward, the slide bar will also be pulled out, and the slide bar can move toward the outside of the cabinet body. When the slide bar moves outward, the inner rod can be driven away from the blocking door. When the inner rod is away from the blocking door, the inner rod can drive the first connecting rod to move, and the first connecting rod can drive the bracket When the bracket is moved, the moving direction of the bracket can be the same as the moving direction of the inner rod. When the bracket moves, it will drive the swing rod to move, and the swing rod can move in the transverse groove of the second connecting rod. When the swing rods contact each other, they will push the second connecting rod in the opposite direction. When the second connecting rod moves, the corresponding inner rod can be away from the baffle door, and the inner rods on both sides of the baffle door will not restrict the baffle door, and the baffle door can be opened, thereby realizing the rapid release of sand and soil, thereby covering the equipment to reduce its contact with oxygen, thereby realizing fire extinguishing. The sand and soil can be reused through the covering, and the sand and soil acquisition path is wide, thereby reducing costs. The sand and soil particles are large and are easy to clean compared to liquid or dust fire extinguishing.

[0020] The invention discloses an electric cabinet capable of internal fire extinguishing and a method for using the same. A heat dissipation port is provided on the cabinet body, and the heat dissipation port can realize the heat dissipation of the electric cabinet in normal times. If a fire occurs, the baffle door will be opened quickly. During the process of the rapid opening of the baffle door, the top frame will be driven to push the inclined frame. The top frame will rotate 90 degrees following the rotation of the baffle door. The top frame can be rotated from a vertical state to a horizontal state, thereby pushing the inclined frame during the rotation, and the inclined frame can move upward. The inclined frame is arranged on the vertical frame, and the vertical frame can move upward. During the upward movement of the vertical frame, the rear rod is driven by the sliding seat. The rear rod is arranged on the blocking plate, and the blocking plate can be rotated to the position of the heat dissipation port, thereby blocking the heat dissipation port, so that external air will not enter the equipment, thereby reducing the oxygen in the equipment, thereby accelerating the combustion of the internal oxygen, and realizing rapid consumption of oxygen. After the baffle door is opened, the upward force on the vertical frame must be greater than the torsion of the second spring, thereby ensuring that the vertical frame will not be reset to cause the opening of the blocking plate.

When the inner rods 13 on both sides are away from the baffle door 11, the baffle door 11 can be quickly opened. After the baffle door 11 is opened, the sand inside the sandbox 3 can be put into the cabinet 1, thereby covering the equipment in the cabinet 1, thereby isolating it from oxygen. During the opening process of the baffle door 11, the baffle door 11 opens to both sides under the impact of the sand. During the opening process, the baffle door 11 will push up the vertical frame 147, and the vertical frame 147 can drive the blocking plate 143 to rotate toward the position of the heat dissipation port 7, thereby blocking the heat dissipation port 7, and oxygen will not enter the cabinet 1. Through the setting, the equipment in the cabinet 1 can reduce the contact with oxygen, thereby achieving rapid fire extinguishing, thereby improving the fire extinguishing efficiency.

[0034] A fixed seat 5 is provided inside the side box 2 of the cabinet 1, and a pushing mechanism 6 is slidably connected to the fixed seat 5.

[0036] When a fire occurs inside the power cabinet, the pull ring 4 can be pulled downward, and the pull ring 4 will drive the triangular seat 604 to move downward. When the triangular seat 604 moves downward, the horizontal plate 601 will be pushed at the same time, and the horizontal plate 601 will move outward, thereby moving away from the cabinet body 1. When the horizontal plate 601 moves outward, the slide bar 603 will also be pulled out, and the slide bar 603 can move toward the outside of the cabinet body 1. When the slide bar 603 moves outward, it can drive the inner rod 13 away from the blocking door 11. When the inner rod 13 is away from the blocking door 11, the inner rod 13 can drive the first connecting rod 122 to move, and the first connecting rod 122 can drive the bracket 123 to move. The moving direction of the bracket 123 can be the same as the moving direction of the inner rod 13, and the bracket 123 moves. When the second connecting rod 125 moves, the corresponding inner rod 13 can be away from the baffle door 11, and the inner rods 13 on both sides of the baffle door 11 will not restrict the baffle door 11, and the baffle door 11 can be opened, thereby realizing the rapid release of sand and soil, thereby covering the equipment to reduce its contact with oxygen, thereby realizing fire extinguishing. The sand and soil can be reused by covering the equipment, and the sand and soil acquisition path is wide, thereby reducing costs. The sand and soil particles are large and are easy to clean compared to liquid or dust fire extinguishing.

[0037] The hypotenuse of the triangular seat 604 is overlapped on the horizontal plate 601, the horizontal plate 601 is parallel to the inner rod 13 inside the cabinet 1, the lower end of the triangular seat 604 is slidably connected to the fixed seat 5 of the cabinet 1, the lower end of the triangular seat 604 penetrates the fixed seat 5, and the corresponding pull ring 4 is rotatably connected to the end of the triangular seat 604 below the fixed seat 5.

[0038] The push mechanism 12 includes a first connecting rod 122, which is detachably connected to the inner rod 13 on one side, and a second connecting rod 125 is detachably connected to the inner rod 13 on the other side. The second connecting rod 125 is provided with a transverse groove 121, and a swing rod 124 is inserted into the transverse groove 121. The other end of the swing rod 124 is rotatably connected to the corresponding bracket 123. By pulling the triangular seat 604, the triangular seat 604 can drive the inner rod 13 on one side, and the inner rod 13 can drive the first connecting rod 122 to move, and the first connecting rod 122 can drive the swing rod 124 to move through the bracket 123, thereby realizing the reverse push of the second connecting rod 125.

[0039] The bracket 123 is in a U-shape as a whole, and swing rods 124 are rotatably connected to both ends of the bracket 123. The swing rods 124 are in an L-shape as a whole, and the swing rods 124 on both sides are respectively slidably connected in the transverse grooves 121 of the second connecting rod 125. When the second connecting rod 125 is pushed in the reverse direction, the inner rod 13 on the same side can be driven away from the blocking door 11, thereby realizing the opening of the blocking door 11.

[0040] The tilting mechanism 14 includes a top frame 141, which is detachably connected to the rotating seat 9 of the side stopper 11. An inclined frame 142 is provided in the rotating direction of the top frame 141, and the inclined frame 142 is provided on the vertical frame 147. A slide seat 146 is provided on the side edge of the vertical frame 147. A rear rod 145 is slidably connected in the slide seat 146. The rear rod 145 is provided on the blocking plate 143. The blocking plate 143 is rotatably connected to the rotating rod 144, and the rotating rod 144 is provided on the cabinet 1. The vertical frame 147 can be lifted up by the top frame 141, and the vertical frame 147 can drive the rear rod 145 through the slide seat 146. The rear rod 145 can be driven by the vertical frame 147 to be parallel, and the rear rod 145 can drive the blocking plate 143 to rotate toward the heat dissipation port 7, thereby blocking the heat dissipation port 7.

[0041] The top frame 141 is L-shaped as a whole, the vertical frame 147 is arranged along the vertical direction of the cabinet 1, the length and width of the blocking plate 143 are greater than the corresponding heat dissipation openings 7, and the heat dissipation openings 7 are respectively located on both sides of the vertical frame 147. The blocking of the blocking plate 143 can prevent the entry of air.

[0042] The reset mechanism 15 includes an insertion rod 152, which is vertically arranged at the bottom end of the cabinet 1. A socket 151 is provided at the position of the vertical frame 147 corresponding to the insertion rod 152. The socket 151 is sleeved on the insertion rod 152 at the bottom. A second spring 153 is sleeved on the insertion rod 152. The second spring 153 is located between the vertical frame 147 and the cabinet 1. One end of the second spring 153 is detachably connected to the vertical frame 147, and the other end of the second spring 153 is detachably connected to the cabinet 1. When the vertical frame 147 is not pushed by the top frame 141, the second spring 153 can pull down the vertical frame 147, and the vertical frame 147 can drive the blocking plate 143 away from the heat dissipation port 7, thereby realizing ventilation of the heat dissipation port 7, thereby realizing the subsequent normal use of the cabinet 1.

[0043] When the baffle door 11 is opened quickly, the top frame 141 will be driven to push the inclined frame 142. When the top frame 141 rotates 90 degrees following the rotation of the baffle door 11, the top frame 141 can be rotated from a vertical state to a horizontal state, thereby pushing the inclined frame 142 during the rotation, and the inclined frame 142 can move upward. The inclined frame 142 is arranged on the vertical frame 147, and the vertical frame 147 can move upward. During the upward movement of the vertical frame 147, the rear rod 145 will be driven by the slide seat 146, and the rear rod 145 is arranged on the blocking plate 143. The blocking plate 143 can be rotated to rotate to the position of the heat dissipation port 7, thereby blocking the heat dissipation port 7, so that external air will not enter the equipment, thereby reducing the oxygen in the equipment, thereby accelerating the combustion of internal oxygen, and realizing rapid consumption of oxygen. After the baffle door 11 is opened, the upward force on the vertical frame 147 must be greater than the torsion of the second spring 153, thereby ensuring that the vertical frame 147 will not be reset to cause the opening of the blocking plate 143.

[0044] like Figure 1-7 As shown, a method for using an internal fire extinguishing power cabinet comprises the following steps:

[0045] S1: First, inject sand into the sandbox 3 for pre-storage. If a fire occurs inside the cabinet 1, the pull ring 4 can be immediately pulled. The pull ring 4 is located inside the side box 2. The personnel can quickly pull the pull ring 4 inside the side box 2. When the pull ring 4 is pulled down, the pull ring 4 will drive the triangular seat 604 to move downward. When the triangular seat 604 moves downward, it will push the horizontal plate 601, and the horizontal plate 601 will move away from the cabinet 1. The sliding rod 603 connected to the horizontal plate 601 will extend to the outside of the cabinet 1. When the sliding rod 603 extends, it will pull the inner rod 13 away from the blocking door 11;

[0046] S2: When the inner rod 13 on one side of the blocking door 11 moves away, one side of the blocking door 11 will not be restricted by the inner rod 13. As the inner rod 13 on one side moves away, the inner rod 13 will drive the first connecting rod 122 to move. The first connecting rod 122 will drive the swinging rod 124 to move to one side through the bracket 123. When the bracket 123 pulls the swinging rod 124 to move, the swinging rods 124 on both sides will move toward the middle of the transverse groove 121 of the second connecting rod 125. When the swinging rods 124 on both sides are in contact, the swinging rods 124 cannot move in the transverse groove 121.

[0047] S3: When the bracket 123 continues to move with the first connecting rod 122, the swing rod 124 on the bracket 123 will be in a state of rotating in the direction of the second connecting rod 125, and the swing rod 124 will push the second connecting rod 125 in the opposite direction. The second connecting rod 125 will be pushed away from the position of the baffle door 11 by the swing rod 124, and the inner rod 13 on the other side will be in a state of moving away from the baffle door 11. The baffle door 11 will be opened after it is not restricted by the inner rod 13, and the sand will fall quickly and adhere to the internal equipment, reducing its contact with oxygen to achieve fire extinguishing. When the baffle door 11 is opened, it will be in a state of rotating, and the top frame 141 on the baffle door 11 will push the vertical frame 147. When the vertical frame 147 moves up, it will drive the blocking plate 143 to rotate toward the position of the heat dissipation port 7. When the blocking plate 143 is parallel to the heat dissipation port 7, the heat dissipation port 7 will be blocked by the blocking plate 143, and the external air will no longer enter the power cabinet, and the amount of oxygen inside the power cabinet can be reduced.

[0048] The working principle of the present invention is as follows: by arranging a sandbox 3 on the power cabinet, sand can be placed in advance inside the sandbox 3; by arranging a side box 2 on the cabinet body 1, a pull ring 4 can be installed inside the side box 2, and the pull ring 4 can control the placement of sand; when a fire occurs inside the power cabinet, the pull ring 4 can be pulled downward, and the pull ring 4 will drive the triangular seat 604 to move downward; when the triangular seat 604 moves downward, the horizontal plate 601 will be pushed up at the same time, and the horizontal plate 601 will move outward, thereby moving away from the cabinet body 1; when the horizontal plate 601 moves outward, the sliding rod 603 will also be pulled out, and the sliding rod 603 can move toward the outside of the cabinet body 1; when the sliding rod 603 moves outward, the inner rod 13 can be driven away from the blocking door 11; when the inner rod 13 is away from the blocking door 11, the inner rod 13 can drive the first connecting rod 122 to move, and the first connecting rod 122 can drive the bracket 1 When the bracket 123 is moved, the moving direction of the bracket 123 can be the same as the moving direction of the inner rod 13. When the bracket 123 moves, it will drive the swing rod 124 to move, and the swing rod 124 can move in the transverse groove 121 of the second connecting rod 125. When the swing rods 124 contact each other, they will push the second connecting rod 125 in the opposite direction. When the second connecting rod 125 moves, the corresponding inner rod 13 can be away from the baffle door 11, and the inner rods 13 on both sides of the baffle door 11 will not restrict the baffle door 11, and the baffle door 11 can be opened, thereby realizing the rapid delivery of sand and soil, thereby covering the equipment to reduce its contact with oxygen, thereby realizing fire extinguishing. The sand and soil can be reused by covering the equipment, and the sand and soil acquisition path is wide, thereby reducing the cost. The sand and soil particles are large, and are convenient to clean compared with liquid or dust fire extinguishing.

[0049] By providing the heat dissipation opening 7 on the cabinet body 1, the heat dissipation opening 7 can realize the heat dissipation of the power cabinet in normal times. If a fire occurs, the baffle door 11 will be opened quickly. During the process of the baffle door 11 being opened quickly, the top frame 141 will be driven to push the inclined frame 142. The top frame 141 will rotate 90 degrees when following the rotation of the baffle door 11. The top frame 141 can be rotated from a vertical state to a horizontal state, thereby pushing the inclined frame 142 during the rotation, and the inclined frame 142 can move upward. The inclined frame 142 is arranged on the vertical frame 147, and the vertical frame 147 can move upward. The vertical frame 147 moves upward. The rear rod 145 will be driven by the slide seat 146, and the rear rod 145 is set on the blocking plate 143, so that the blocking plate 143 can be rotated to the position of the heat dissipation port 7, thereby blocking the heat dissipation port 7, so that the external air will not enter the equipment, thereby reducing the oxygen in the equipment, thereby accelerating the combustion of internal oxygen, and realizing rapid consumption of oxygen. After the baffle door 11 is opened, the upward force on the vertical frame 147 must be greater than the torsion of the second spring 153, thereby ensuring that the vertical frame 147 will not be reset to cause the opening of the blocking plate 143.

If a fire occurs inside the cabinet (1), the pull ring (4) can be immediately pulled. The pull ring (4) is located inside the side box (2). A person can quickly pull the pull ring (4) inside the side box (2). When the pull ring (4) is pulled downward, the pull ring (4) drives the triangular seat (604) to move downward. When the triangular seat (604) moves downward, it pushes the horizontal plate (601). The horizontal plate (601) moves away from the cabinet (1). The sliding rod (603) connected to the horizontal plate (601) extends toward the outside of the cabinet (1). When the sliding rod (603) extends, it pulls the inner rod (13) away from the blocking door (11); S2: When the inner rod (13) on one side of the blocking door (11) moves away, one side of the blocking door (11) is not restricted by the inner rod (13). As the inner rod (13) on one side moves away, the inner rod (13) drives the first connecting rod (122) to move. The first connecting rod (122) drives the swing rod (124) to move toward one side through the bracket (123). When the bracket (123) pulls the swing rod (124) to move, the swing rods (124) on both sides move toward the middle of the transverse groove (121) of the second connecting rod (125).
