Description

Technical Field

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

[0002] HFC-227ea can reliably extinguish Class B and C fires and electrical fires at a relatively low extinguishing concentration. It requires little storage space, has a high critical temperature and a low critical pressure, and can be liquefied and stored at room temperature. It leaves no particles or oily residue after release and has no damaging effect on the atmospheric ozone layer. Its atmospheric residence time is 31 to 42 years, meeting environmental protection requirements. HFC-227ea gas fire extinguishing products are essential components of firefighting systems, leveraging the extinguishing properties of HFC-227ea gas. Currently, HFC-227ea gas is stored in a fire extinguisher bottle, which is then placed in a fire extinguishing cabinet to protect it.

[0003] For example, in a prior art heptafluoropropane gas fire extinguishing cabinet with patent number CN202321303854.8, the left panel and the rear panel are connected by a left oblique panel, and the right panel and the rear panel are connected by a right oblique panel, so that the two vertical corners on the rear side of the cabinet form a structure similar to a chamfer. The existence of this chamfer structure can reduce the use of plate materials, thereby reducing production costs.

[0004] However, when this type of fire extinguisher stores a heptafluoropropane gas fire extinguishing agent bottle, the heptafluoropropane gas fire extinguishing agent bottle cannot be limited and fixed. As a result, when the fire extinguisher is accidentally hit, the heptafluoropropane gas fire extinguishing agent bottle shakes in the fire extinguisher and rubs and collides with the inner wall of the fire extinguisher, causing damage to the heptafluoropropane gas fire extinguishing agent bottle. The stability performance is poor and the use is inconvenient. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology and to propose a heptafluoropropane gas fire extinguishing cabinet.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A heptafluoropropane gas fire extinguishing cabinet comprises a lower fixed cylinder, a return spring is vertically fixed to the bottom of the lower fixed cylinder, a placement plate is embedded in the lower interior of the lower fixed cylinder, an external connection plate is vertically fixed to the top outer wall of the placement plate, a top plate is fixed to the top of each external connection plate, an upper fixed cylinder is fixed above the lower fixed cylinder through a connecting rod, a limiting column is fixed inside the upper fixed cylinder, a spring and a limiting block are nested on the outside of the limiting column, a fixed block is fixed on the top of the limiting block, a clamping strip is vertically fixed to the back of the lower fixed cylinder, a connecting disk is nested on the outside of the clamping strip, and a mounting plate is provided on the outside of the connecting disk.

[0008] Preferably, an extension groove is provided in the lower inner opening of the lower fixed cylinder, the cross-sectional area of the extension groove is larger than the cross-sectional area of the inner opening of the lower fixed cylinder, the cross-sectional area of the extension groove is consistent with the cross-sectional area of the placement plate, and the placement plate rises and falls vertically in the extension groove at the lower inner bottom of the lower fixed cylinder.

[0009] Preferably, three groups of hidden grooves arranged in an annular shape are equidistantly arranged inside the upper fixed cylinder from top to bottom, the fixed block and the top plate are just embedded in the hidden grooves, and an opening is provided at one end of the hidden groove close to the middle of the upper fixed cylinder.

[0010] Preferably, the bottom of the top plate is in close contact with the outer wall of the fixed block, and the bottom of the top plate and the outer wall of the fixed block are both provided with inclined surfaces that are in close contact with each other, and the end of the fixed block close to the middle of the upper fixed cylinder is fixed with anti-slip strips equidistantly from top to bottom.

[0011] Preferably, the limiting block slides horizontally on the outer wall of the limiting column, the outer side of the spring is in close contact with the limiting block, and the fixing block slides horizontally in the hidden groove.

[0012] Preferably, a card slot that fits with the card strip is provided inside the connecting disk, and the connecting disk rotates clockwise and counterclockwise in the mounting plate.

[0013] 1. When the heptafluoropropane gas fire extinguishing agent bottle passes through the upper fixed cylinder from top to bottom and is placed on the placement plate of the lower fixed cylinder, the heptafluoropropane gas fire extinguishing agent bottle pushes the placement plate downward due to the action of gravity. At the same time as the placement plate moves downward, the top plate is pulled downward through the external plate, so that the top plate pushes the fixing block downward to extend from the upper fixed cylinder and move toward the center of the circle of the upper fixed cylinder until it is tightly attached to the outer wall of the heptafluoropropane gas fire extinguishing agent bottle, thereby achieving rapid fixation of the heptafluoropropane gas fire extinguishing agent bottle, the heptafluoropropane gas fire extinguishing agent bottle will not shake in the device, the stability is high, and the protection effect of the heptafluoropropane gas fire extinguishing agent bottle is better.

[0014] 2. After the mounting plate is fixed to the wall, the device can be quickly assembled and fixed to the wall by inserting the clip strip on the back of the lower fixing tube into the connection plate inside the mounting plate from top to bottom. The installation is carried out in two separate steps to avoid the device falling from the wall during installation. The installation is now easier. At the same time, the lower fixing tube can be pushed clockwise or counterclockwise to rotate in front of the mounting plate according to actual conditions to adjust the overall direction of the upper part of the upper fixing tube, which is more flexible.

[0021] Example 1, with reference to Figure 1-4 A heptafluoropropane gas fire extinguishing cabinet includes a lower fixed cylinder 1, a return spring 101 is vertically fixed to the bottom of the lower fixed cylinder 1, a placement plate 102 is embedded in the lower interior of the lower fixed cylinder 1, an external plate 103 is vertically fixed to the top outer wall of the placement plate 102, and a top plate 104 is fixed to the top of the external plate 103, an upper fixed cylinder 2 is fixed to the top of the lower fixed cylinder 1 through a connecting rod, a limiting column 201 is fixed inside the upper fixed cylinder 2, a spring 202 and a limiting block 203 are nested on the outside of the limiting column 201, a fixed block 204 is fixed on the top of the limiting block 203, a clamping strip 3 is vertically fixed to the back of the lower fixed cylinder 1, a connecting disk 301 is nested on the outside of the clamping strip 3, and a mounting plate 302 is provided on the outside of the connecting disk 301.

[0022] An extension groove is provided in the lower opening of the lower fixed cylinder 1. The cross-sectional area of the extension groove is larger than the cross-sectional area of the inner opening of the lower fixed cylinder 1. The cross-sectional area of the extension groove is consistent with the cross-sectional area of the placement plate 102. The placement plate 102 is vertically raised and lowered in the extension groove at the lower interior of the lower fixed cylinder 1.

[0023] The interior of the upper fixed cylinder 2 is provided with three groups of circular hidden grooves arranged equidistantly from top to bottom. The fixing block 204 and the top plate 104 are both exactly embedded in the hidden grooves. The hidden groove is provided with an opening at one end near the middle of the upper fixed cylinder 2.

[0024] When the HFC-227ea fire extinguishing agent bottle passes through the upper fixing cylinder 2 from top to bottom and is placed on the placement plate 102 of the lower fixing cylinder 1, the HFC-227ea fire extinguishing agent bottle pushes the placement plate 102 downward due to the action of gravity. When the placement plate 102 moves downward, the top plate 104 is pulled downward through the external plate 103, so that the top plate 104 pushes the fixing block 204 downward to extend from the upper fixing cylinder 2 and move toward the center of the circle of the upper fixing cylinder 2 until it is tightly attached to the outer wall of the HFC-227ea fire extinguishing agent bottle, thereby achieving rapid fixation of the HFC-227ea fire extinguishing agent bottle. The HFC-227ea fire extinguishing agent bottle is not easy to shake in the device, and has high stability.

[0025] The bottom of the top plate 104 is in close contact with the outer wall of the fixed block 204. The bottom of the top plate 104 and the outer wall of the fixed block 204 are both provided with inclined surfaces that are in close contact with each other. The end of the fixed block 204 close to the middle of the upper fixed cylinder 2 is fixed with anti-slip strips at equal distances from top to bottom.

[0026] When the protective strip fixed on the inner wall of the fixing block 204 is tightly attached to the heptafluoropropane gas fire extinguishing agent bottle, the stability of the fixing of the heptafluoropropane gas fire extinguishing agent bottle can be further improved;

[0027] The limiting block 203 slides horizontally on the outer wall of the limiting column 201, the outer side of the spring 202 is in close contact with the limiting block 203, and the fixing block 204 slides horizontally in the hidden groove;

[0028] When the staff pulls out the HFC-227ea gas fire extinguishing agent bottle from the bottom to the top, the return spring 101 pushes the placement plate 102 to move up and return to its original position. The placement plate 102 pushes the top plate 104 to move up through the external plate 103. At the same time, the spring 202 returns to its original position and pushes the fixing block 204 to be embedded in the hidden groove through the limit block 203.

[0029] Example 2: Example 2 differs from Example 1 in that, in this embodiment, a card slot that fits with the card strip 3 is provided inside the connection disk 301, and the connection disk 301 rotates clockwise and counterclockwise in the mounting plate 302;

[0030] After the mounting plate 302 is fixed to the wall with expansion bolts, the clamping strip 3 on the back of the lower fixing tube 1 is inserted from top to bottom into the connecting plate 301 inside the mounting plate 302, so that the device can be quickly assembled and fixed on the wall. The installation is carried out in two separate steps to avoid the device falling off the wall during installation, making installation easier.

[0031] When the mounting plate 302 is installed on the wall at an angle, the lower fixing cylinder 1 can be pushed to rotate clockwise or counterclockwise in front of the mounting plate 302 according to actual conditions to adjust the overall direction of the upper part of the upper fixing cylinder 2, which is highly flexible.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
