Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a gas fire-extinguishing system for a charging cabinet. Background Art

[0002] Charging cabinets are used to charge batteries. When batteries are overcharged and burst, the electrolyte will produce a large amount of flammable vapors, such as hydrogen and methane. These gases can easily cause explosions when mixed with air at high temperatures. Therefore, charging cabinets often need to be equipped with fire extinguishing systems to extinguish fires as soon as possible after a fire breaks out in the charging cabinet.

[0003] The patent number CN213936922U discloses a charging cabinet, including a charging cabinet, a fire extinguishing tank, a fuse, a counterweight, a cylindrical pile and a rope. When the charging cabinet catches fire, the fuse can be melted by high temperature, so that the counterweight can fall, driving the rope to lift and shake the fire extinguishing tank; the charging cabinet disclosed in the patent also includes a connecting rod, a movable handle, a powder spraying tube and a nozzle. The movable handle is pressed down by the connecting rod so that the powder in the fire extinguishing tank enters the powder spraying tube and is sprayed out through the nozzle. Although the fire extinguishing tank in the charging cabinet can be shaken and evenly mixed with the powder inside the fire extinguishing tank under the action of the counterweight, the fire extinguishing efficiency is improved, and the movable handle is automatically pressed to spray powder to extinguish the fire when a fire occurs, and no additional power supply system is required. However, in actual use, only one fire extinguishing tank is set in the charging cabinet, resulting in a limited amount of powder stored therein, resulting in the inability to completely extinguish the fire in the charging cabinet, thereby affecting the fire extinguishing effect of the charging cabinet.

[0026] The utility model provides a technical solution:

[0027] See also Figure 1 and Figure 2 A charging cabinet gas fire extinguishing system in this embodiment includes a fire extinguishing cabinet 100, a cabinet door 101 and an interface 102 arranged on the upper part of the fire extinguishing cabinet 100, a universal wheel 110 is arranged at the bottom of the fire extinguishing cabinet 100, a mounting frame 120 is arranged on the outer wall of the fire extinguishing cabinet 100, and both sides of the mounting frame 120 are provided with a liftable lifting rod 130, the lower end of the lifting rod 130 is provided with a friction block 131 for contacting the ground, and the mounting frame 120 is provided with a driving component 140 for driving the lifting rod 130 to rise and fall.

[0028] The charging cabinet gas fire extinguishing system in the present embodiment is used to extinguish fires occurring in the charging cabinet. The charging cabinet in the present embodiment adopts the structure of patent number CN213936922U, which is provided with a powder spraying tube extending out of the charging cabinet and a nozzle arranged on the powder spraying tube; the fire extinguishing cabinet in the present embodiment is provided with a holding chamber with an opening on one side, and the holding chamber is used to hold a plurality of fire extinguishing cans. When in actual use, the fire extinguishing cans are connected to the interface 102 through a conduit, so that when in actual use, the interface 102 is connected to the powder spraying tube extending out of the charging cabinet, so that when the fire extinguishing can is opened, the powder in the fire extinguishing can enter the powder spraying tube through the conduit through the joint and is sprayed out through the nozzle, thereby realizing fire extinguishing in the charging cabinet; compared with the existing charging cabinet in which only one fire extinguishing can is provided, the charging cabinet gas fire extinguishing system in the present embodiment can simultaneously utilize a plurality of fire extinguishing cans in the fire extinguishing cabinet 100 to provide more powder into the charging cabinet, thereby better improving the fire extinguishing effect;

[0029] The cabinet door 101 is openably disposed at the opening of the containing cavity. With this structure, the fire extinguishing tank in the fire extinguishing cabinet 100 can be operated by opening and closing the cabinet door 101.

[0030] The universal wheels 110 are provided to facilitate the movement of the fire extinguishing cabinet 100;

[0031] In actual use, this embodiment can drive the lifting rod 130 to move upward through the driving component 140, and the lifting rod 130 drives the friction block 131 to move up and away from the ground, thereby reducing the friction between the fire extinguisher 100 and the ground. At this time, the fire extinguisher 100 can be driven to move by the universal wheel 110; when reaching the specified position, the lifting rod 130 is driven downward by the driving component 140, and the lifting rod 130 drives the friction block 131 to move downward until it touches the ground, thereby increasing the friction between the fire extinguisher 100 and the ground, thereby fixing the fire extinguisher 100, and then connecting the pipe of the fire extinguishing system in the charging cabinet to the interface 102, so that the fire extinguisher 100 can be connected to the fire extinguishing system in the charging cabinet.

[0032] The side of the friction block 131 in contact with the ground is relatively rough to increase the friction between the friction block 131 and the ground. When the fire extinguisher 100 needs to be parked in a relatively smooth area, the friction block 131 can better fix the fire extinguisher 100 in a designated position.

[0033] The mounting frame 120 is fixed to the outer wall of the fire extinguishing cabinet 100 by welding. The mounting frame 120 is U-shaped and is wrapped around the outside of the fire extinguishing cabinet 100 with its opening facing the cabinet door 101 to facilitate the opening and closing of the cabinet door 101.

[0034] Wherein, through the setting of the driving component 140, the driving component 140 can drive the lifting rod 130 to rise and fall.

[0035] like Figure 3 and Figure 4 As shown, in this embodiment, the driving assembly 140 includes a bottom plate 300 arranged on both sides of the mounting frame 120, the bottom plate 300 is arranged along the height direction of the fire extinguishing cabinet 100, and a slide groove 301 is arranged on the side of the bottom plate 300 facing the outside of the fire extinguishing cabinet 100 along its length direction, and a groove is arranged on the side wall opposite to the slide groove 301 along its length direction, and a slidable slider 310 is arranged in the slide groove 301, and the lower end of the slider 310 is connected to the lifting rod 130, and a position is arranged on the side wall opposite to the slider 310 A protrusion 450 slides in the corresponding groove 451; a hinge seat 320 is provided at the upper end of the base plate 300, and a rotating rod 330 is provided on the hinge seat 320, and the middle part of the rotating rod 330 is hingedly connected to the hinge seat 320. The lower end of the rotating rod 330 is provided with a connecting rod 340 whose upper end is hingedly connected to the rotating rod 330, and the lower end of the connecting rod 340 is hingedly connected to the slider 310. The rotation of the rotating rod 330 is used to drive the connecting rod 340 to drive the slider 310 to rise and fall, thereby realizing the lifting and falling of the lifting rod 130.

[0036] In actual use of this embodiment, when the fire extinguisher cabinet 100 needs to be moved, the upper end of the rotating rod 330 is pulled in a direction away from the cabinet door 101, so that the rotating rod 330 rotates around the middle hinge point so that its lower end is close to the cabinet door 101, driving the connecting rod 340 to drive the slider 310 to move upward in the slide groove 301, thereby driving the lifting rod 130 to move upward, and releasing the friction block 131 from contacting the ground;

[0037] When the fire extinguisher cabinet 100 needs to be fixed, the upper end of the rotating rod 330 is pulled toward the cabinet door 101, and the rotating rod 330 rotates around the middle hinge point so that its lower end is away from the cabinet door 101, driving the connecting rod 340 to drive the slider 310 to move downward in the slide groove 301, thereby driving the connecting plate 150 to move downward until it is consistent with the length direction of the bottom plate 300, so that the friction block 131 contacts the ground;

[0038] The arrangement of the groove 451 and the protrusion 450 restricts the slider 310 so that it can only move up and down and slide in the slide groove 301.

[0039] The upper end of the bottom plate 300 is fixedly connected to the mounting frame 120 by welding, so that the installation of the bottom plate 300 is more stable;

[0040] The lower end of the rotating rod 330 is hingedly connected to the connecting rod 340. The lower end of the rotating rod 330 is provided with a rotating groove 460 into which the connecting rod 340 extends. The rotating groove 460 is provided with a hinge shaft that penetrates the connecting rod 340. With this structure, the hinge connection between the two is preferably achieved.

[0041] Wherein, by setting the hinge seat 320, the middle part of the rotating rod 330 can be hingedly connected to the hinge seat 320, so that it rotates on the bottom plate 300 with the hinge seat 320 as the center;

[0042] The connecting rod 340 and the sliding block 310 are rotationally connected via a pin.

[0043] like Figure 4 As shown, in this embodiment, the hinge seat 320 includes a pad 420 and a rotating shaft 410 arranged on the pad 420, the rotating rod 330 is provided with an axial hole 400 for the rotating shaft 410 to pass through, and the rotating rod 330 is provided with a mounting cavity 401 connected to the axial hole 400 at the upper end, and a slidable connecting plate 150 is provided in the mounting cavity 401, and the upper end of the connecting plate 150 extends out of the mounting cavity 401, and the connecting plate 150 located in the mounting cavity 401 is provided with a limiting rod 430 that can extend into the axial hole 400, and the side wall of the rotating shaft 410 is provided with a plurality of limiting holes 411 for the limiting rod 430 to extend into.

[0044] In actual use of this embodiment, the connecting plate 150 is pulled out from the installation cavity 401, and the connecting plate 150 drives the limiting rod 430 to move upward, so that the lower end of the limiting rod 430 withdraws from the limiting hole 411, thereby releasing the limit on the rotating rod 330, so that the rotating rod 330 can rotate, that is, the rotating rod 330 rotates around the middle hinge point;

[0045] The connecting plate 150 is pushed into the installation cavity 401, and the connecting plate 150 drives the limiting rod 430 to move downward, so that the lower end of the limiting rod 430 extends into the limiting hole 411, thereby limiting the rotation rod 330, so that the rotation rod 330 cannot rotate, that is, the position of the friction block 131 can be kept fixed, so that it can be kept in a state of contact with the ground and in a state of being released from contact with the ground;

[0046] A cover plate 470 is disposed above the rotating shaft 410 and blocks the outer wall of the rotating rod 330. By means of the matching arrangement of the cover plate 470, the rotating shaft 410, the pad 420 and the shaft hole 400, the rotating rod 330 can be preferably connected to the bottom plate 300 by rotating around the rotating shaft 410.

[0047] Among them, through the setting of the installation cavity 401, the connecting plate 150, the limiting rod 430 and the limiting hole 411, the connecting plate 150 can slide in the installation cavity 401, driving the limiting rod 430 to extend into or withdraw from the limiting hole 411, thereby realizing the switching of the state of the friction block 131.

[0048] like Figure 1-Figure 3As shown, in this embodiment, the upper ends of the connecting plates 150 located on both sides of the mounting frame 120 are connected by handles 160, and the handles 160 are arranged around the outer wall of the fire extinguisher cabinet 100. The rotating rod 330 rotates to cause the friction block 131 to move upward and drive the handle 160 away from the outer wall of the fire extinguisher cabinet 100. The rotating rod 330 rotates to cause the friction block 131 to move downward and drive the handle 160 to fit and be stored on the outer wall of the fire extinguisher cabinet 100.

[0049] When the fire extinguisher 100 needs to be moved, the handle 160 is pulled downward to move the handle 160 away from the fire extinguisher 100, and the handle 160 drives the connecting rod 340 to move, and the connecting rod 340 drives the rotating rod 330 to rotate toward the cabinet door 101, so that the connecting rod 340 drives the slider 310 to move upward in the slide groove 301, and the contact between the friction block 131 and the ground is released. At this time, the movement of the fire extinguisher 100 is achieved by pushing the handle 160; when the fire extinguisher 100 needs to be fixed, the handle 160 is pushed upward to make the handle 160 close to the outer wall of the fire extinguisher 100 to complete the storage, and the handle 160 drives the connecting rod 340 to move, and the connecting rod 340 drives the rotating rod 330 to rotate in the opposite direction of the cabinet door 101, so that the connecting rod 340 drives the slider 310 to move downward in the slide groove 301, so that the contact between the friction block 131 and the ground is released, that is, the fire extinguisher 100 is better fixed;

[0050] The provision of the handle 160 makes it more convenient to move the fire extinguishing cabinet 100.

[0051] like Figure 4 As shown, in this embodiment, an operating port 441 connected to the installation cavity 401 is provided on the side of the rotating rod 330, and an operating block 440 passing through the operating port 441 is provided on the connecting plate 150. The operating block 440 is located in the operating port 441 and slides to drive the connecting plate 150 to slide in the installation cavity 401.

[0052] In actual use of this embodiment, when the fire extinguisher 100 needs to be moved, the operating block 440 is pushed to move it along the operating opening 441 toward the upper end of the rotating rod 330, thereby increasing the portion of the connecting plate 150 extending out of the mounting cavity 401, thereby driving the limiting rod 430 to exit the limiting hole 411, and releasing the limiting of the rotating rod 330. When the fire extinguisher 100 needs to be fixed, the operating block 440 is pushed to move it along the operating opening 441 away from the upper end of the rotating rod 330, thereby reducing the portion of the connecting plate 150 extending out of the mounting cavity 401, thereby driving the limiting rod 430 to extend into the limiting hole 411, and achieving the limiting of the rotating rod 330.

[0053] Among them, the setting of the operating block 440 makes it more convenient to operate the driving component 140.

[0054] like Figure 5As shown, in this embodiment, a pin hole 510 is provided on the limit rod 430, and a locking hole 520 is provided on the rotating rod 330 to match the pin hole 510. A locking pin 500 is provided in the locking hole 520 and can be inserted into the corresponding pin hole 510 to limit the limit rod 430.

[0055] When this embodiment is actually used, when the locking pin 500 is inserted into the pin hole 510 and the locking hole 520, the limit rod 430 cannot move, thereby completing the locking of the limit rod 430, so that the limit rod 430 is inserted into the limit hole 411, that is, the position of the friction block 131 is fixed; when the locking pin 500 is pulled out of the pin hole 510 and the locking hole 520, the limit rod 430 can move in the installation cavity 401 and the shaft hole 400, thereby releasing the lock of the limit rod 430.

[0056] Working principle: When the fire extinguisher 100 needs to be moved, first pull the locking pin 500 out of the corresponding locking hole 520 and pin hole 510, then push the operating block 440 upward, and then pull the handle 160 downward to make the driving assembly 140 drive the lifting rod 130 to move upward, and the lifting rod 130 drives the friction block 131 off the ground, thereby releasing the fixation of the fire extinguisher 100, and after the handle 160 is in the unfolded state, push the operating block 440 downward, and then extend the locking pin 500 into the pin hole 510 and the locking hole 520, so that the fire extinguisher 100 can be kept in a mobile state.

[0057] When it is necessary to fix the fire extinguisher cabinet 100, first pull the locking pin 500 out of the locking hole 520 and the pin hole 510, then push the operating block 440 upwards, and then push the handle 160 upwards to store it. At the same time, the driving assembly 140 drives the lifting rod 130 to move downward, and the lifting rod 130 drives the friction block 131 to move downward to contact the ground, thereby fixing the fire extinguisher cabinet 100, and then push the operating block 440 downwards to extend the locking pin 500 into the locking hole 520 and the pin hole 510, so that the fire extinguisher cabinet 100 can be kept in a fixed state; then connect the interface 102 to the powder spraying tube extending out of the charging cabinet, open the fire extinguisher tank to extinguish the fire in the charging cabinet.
