Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical devices, in particular to an electromechanical safety automatic fire extinguishing device. Background Art

[0002] Control cabinet is a kind of equipment commonly used in electromechanical engineering. Control cabinet is to assemble switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. Its layout should meet the requirements of normal operation of the power system, facilitate maintenance, and not endanger the safety of personnel and surrounding equipment.

[0003] However, there are multiple heat dissipation holes on the side walls of the control cabinet. When a fire occurs inside the control cabinet, if these heat dissipation holes are not blocked, the outside air can easily enter the electromechanical cabinet through these heat dissipation holes, increasing the spread of the fire and affecting the fire fighting work. Therefore, we need to consider how to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art, and to propose an electromechanical safety automatic fire extinguishing device, which is coordinated by structures such as gears, racks and rotating shafts. When a fire occurs, multiple baffles move down to block multiple heat dissipation holes, and at the same time, the pressure rod moves down to squeeze the fire extinguisher, so that dry powder can be sprayed, thereby achieving the effect of automatic fire extinguishing.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An electromechanical safety automatic fire extinguishing device comprises a cabinet, both side walls of the cabinet are provided with a plurality of heat dissipation holes, each of the heat dissipation holes is fixedly connected with a dustproof net, electromechanical equipment is installed at the bottom of the cabinet, a smoke sensor is installed at an inner wall of one side of the cabinet, a fire extinguisher is installed at the bottom of the cabinet, two guide rods are fixedly connected between the inner top and inner bottom of the cabinet, both guide rods are slidably connected with racks, one inner wall of one side of the cabinet is rotatably connected with two rotating shafts, gears are installed on the two rotating shafts, both gears are meshed with corresponding racks, three baffles are fixedly connected at one side of the two racks, a pressure rod is fixedly connected to one side of one of the baffles, and a driving mechanism for driving one of the rotating shafts to rotate is provided on the outer wall of the cabinet.

[0007] Preferably, a sealing door is provided on one side of the cabinet, one side of the sealing door is rotatably connected to the cabinet, and the other side is connected to the cabinet by a snap-fit ​​connection.

[0011] Preferably, the strip plate is hollow inside, a plurality of nozzles are fixedly connected to the lower end of the strip plate, and the fire extinguisher is connected to the inside of the strip plate through a hose.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. Gears, racks, baffles and other structures are set up. When a fire occurs, the rack moves down with multiple baffles to cover multiple heat dissipation holes, making the interior of the cabinet a closed space, reducing air entry and thus weakening the fire. The rack moves down and the pressure rod moves down to squeeze the fire extinguisher, so that it can automatically spray dry powder to extinguish the fire;

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 6 , an electromechanical safety automatic fire extinguishing device, comprising a cabinet 1, a sealed door 2 is provided on one side of the cabinet 1, one side of the sealed door 2 is rotatably connected to the cabinet 1, and the other side is connected to the cabinet 1 by a snap connection, a plurality of heat dissipation holes 3 are provided on both side walls of the cabinet 1, a dustproof net 4 is fixedly connected to each heat dissipation hole 3, and the dustproof net 4 can prevent some impurities from entering the interior of the cabinet 1, an electromechanical device 5 is installed at the bottom of the cabinet 1, a smoke sensor 6 is installed on the inner wall of one side of the cabinet 1, and a fire extinguisher 7 is installed at the bottom of the cabinet 1, the smoke sensor 6, the fire extinguisher 7 and the electric control system of the device are all prior art, and are not described in detail here, two guide rods 8 are fixedly connected between the inner top and the inner bottom of the cabinet 1, racks 9 are slidably connected to the two guide rods 8, and two rotating shafts 10 are rotatably connected to the inner wall of one side of the cabinet 1;

[0024] Among them, gears 11 are installed on the two rotating shafts 10, and the two gears 11 are meshed with the corresponding racks 9. Three baffles 12 are fixedly connected to one side of the two racks 9. When a fire occurs, each baffle 12 blocks the corresponding row of heat dissipation holes 3 to prevent the outside air from entering the cabinet 1 through these heat dissipation holes 3 and increasing the fire. A pressure rod 13 is fixedly connected to one side of one of the baffles 12. The pressure rod 13 is an L-shaped rod and is located above the switch of the fire extinguisher 7. When multiple baffles 12 move down to block multiple heat dissipation holes 3, the pressure rod 13 will move down and then squeeze the switch of the fire extinguisher 7 so that the fire extinguisher 7 sprays dry powder to extinguish the fire, thereby achieving the effect of automatic fire extinguishing. Two transmission wheels 14 are installed on the two rotating shafts 10, and the two transmission wheels 14 are connected through a belt 15.

[0025] Among them, the outer wall of the cabinet 1 is provided with a driving mechanism for driving one of the rotating shafts 10 to rotate. The driving mechanism is a motor 16 installed on the outer wall of the cabinet 1. The motor 16 is a servo motor. The end of the output shaft of the motor 16 passes through the cabinet 1 and is fixedly connected to one of the rotating shafts 10. A slide rail 17 is installed on the top of the cabinet 1. A slider 18 is slidably connected in the slide rail 17. The lower end of the slider 18 is fixedly connected to a strip plate 19. The strip plate 19 is hollow inside. A plurality of nozzles 20 are fixedly connected to the lower end of the slider 18. The fire extinguisher 7 is connected to the inside of the strip plate 19 through a hose 21. The dry powder sprayed by the fire extinguisher 7 enters the inside of the strip plate 19 and is finally sprayed out through the plurality of nozzles 20. In this process, the slide rail 17 and the slider 18 cooperate to make the strip plate 19 move back and forth with the plurality of nozzles 20, so that as much dry powder as possible is sprayed around the fire, thereby increasing the spraying range and achieving a better fire extinguishing effect.

[0026] In the utility model, when the cabinet 1 is on fire, the smoke sensor 6 generates an electrical signal to start the motor 16 and the slide rail 17. After the motor 16 is started, the two rotating shafts 10 are rotated through the transmission relationship between the transmission wheel 14 and the belt 15, thereby rotating the two gears 11. The rotation of the two gears 11 causes the corresponding racks 9 meshing therewith to move downward. The downward movement of the two racks 9 causes the multiple baffles 12 to move downward, thereby shielding the multiple heat dissipation holes 3, thereby sealing the interior of the cabinet 1 and reducing the entry of air to reduce the fire. The downward movement of one of the baffles 12 also causes the corresponding pressure rod 13 to move downward, thereby squeezing the switch of the fire extinguisher 7, thereby enabling the fire extinguisher 7 to work automatically and spray dry powder on the interior of the cabinet 1.

[0027] After the fire extinguisher 7 is squeezed, the dry powder enters the strip plate 19 through the hose 21, and is finally sprayed out through multiple nozzles 20 to extinguish the fire. After the slide rail 17 is started, it will move with the slider 18, and then move with the strip plate 19 and the multiple nozzles 20. By reciprocating the strip plate 19 and the multiple nozzles 20, the spraying range of the dry powder is increased, so that it can be sprayed around the fire as much as possible, achieving a better fire extinguishing effect, thereby realizing automatic fire extinguishing.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
