Description

Technical Field

[0001] This utility model relates to the field of single-unit cabinet-type carbon dioxide fire extinguishing systems, and in particular to a single-unit cabinet-type carbon dioxide fire extinguishing device. Background Technology

[0002] A cabinet-type carbon dioxide gas fire extinguishing system consists of a fire extinguishing control cabinet, detection devices, alarm devices, spraying devices, and carbon dioxide extinguishing gas cylinders. When the detection device detects a fire signal, it sends a signal to the fire extinguishing control cabinet. The fire extinguishing control cabinet then releases carbon dioxide gas from the cabinet-type carbon dioxide gas fire extinguishing system to suppress the fire source, thereby achieving the fire extinguishing effect.

[0003] Carbon dioxide fire extinguishing cylinders should be stored in a dry and well-ventilated place. Carbon dioxide fire extinguishers are very sensitive to humid environments, so they should be stored in a dry and well-ventilated place.

[0004] However, in current cabinet-type carbon dioxide fire extinguishing systems, the carbon dioxide extinguishing cylinders are placed directly inside the cabinet, which is placed on the ground. The ground temperature is low, and the low temperature can easily be conducted directly to the carbon dioxide extinguishing cylinders through the cabinet, resulting in a shorter storage time for the carbon dioxide extinguishing cylinders.

[0005] Meanwhile, a 70L carbon dioxide fire extinguishing cylinder has a steel cylinder weight of 20KG and a fire extinguishing agent filling capacity of 42KG, making the entire 70L carbon dioxide fire extinguishing cylinder weigh 62KG. At this weight, it is extremely difficult to move by hand, especially when placed inside a cabinet. Therefore, it is necessary to suspend the top of the carbon dioxide fire extinguishing cylinder and use a forklift to lift the bottom of the carbon dioxide fire extinguishing cylinder to prevent it from shaking. However, after the carbon dioxide fire extinguishing cylinder is placed inside the cabinet, it is difficult to remove the forklift forks. When it is pulled outward, it causes the carbon dioxide fire extinguishing cylinder to shake, which is extremely unsafe. Utility Model Content

[0006] The purpose of this invention is to provide a single-unit cabinet-type carbon dioxide fire extinguishing device, which has the advantages of facilitating the support and erection of carbon dioxide fire extinguishing cylinders, preventing moisture inside the carbon dioxide fire extinguishing cylinders, and facilitating the placement of carbon dioxide fire extinguishing cylinders by forklifts.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A single-unit cabinet-type carbon dioxide fire extinguishing device includes a cabinet, a carbon dioxide fire extinguishing cylinder, and a support base. The support base is fixedly located at the lower end of the cabinet, and the carbon dioxide fire extinguishing cylinder is located at the top of the support base.

[0009] The support base includes a base plate and two sets of support components. The base plate is fixedly located on the inner bottom wall of the cabinet. The two sets of support components are respectively fixedly located on the top left and right sides of the base plate. The two sets of support components are placed symmetrically and mirror-imagely along the longitudinal central axis of the base plate.

[0010] The support assembly on the right side includes a first support block, a second support block, a connecting plate, and three guide rods. Both the first and second support blocks are rectangular strips. The first support block is fixed longitudinally at the top right of the base plate. Three first circular through holes are arranged in an array from front to back on the left side of the first support block. The three guide rods are placed horizontally and are slidably inserted into the three first circular through holes. The second support block is fixed longitudinally at the left side of the three guide rods. The connecting plate is fixed longitudinally at the right side of the three guide rods. A first spring is fitted on the portion of each guide rod between the second and first support blocks, and a second spring is fitted on the portion of each guide rod between the connecting plate and the first support block. Several steel ball rollers are fixedly arranged in an array from front to back on the top and bottom of the second support block.

[0011] The preferred solution is as follows:

[0012] Preferably, each of the first circular perforations is provided with a linear bearing, each linear bearing is connected to its corresponding first support block flange, and each guide rod is inserted into its corresponding linear bearing.

[0013] Preferably, the top of the second support block has a plurality of second circular perforations arranged in an array from front to back;

[0014] Several of the ball bearing rollers are plunger-type ball bearing rollers, and each of the second circular through holes is provided with a ball bearing roller. Each of the ball bearing rollers is connected to the flange of the second support block.

[0015] Preferably, the left four sides of the second support block located on the right side are chamfered.

[0016] Preferably, the top of the base plate is flush with the bottom of the opening on the front side of the cabinet, the bottom of the base plate has downward bending edges at all four corners, and the bottom of the base plate is fixedly provided with several reinforcing plates.

[0017] Preferably, the bottom of the lower steel ball rollers abuts against the top of the base plate, and the bottom of the upper steel ball rollers is 0.5-0.8mm lower than the top of the first support block.

[0018] Preferably, the right side of each of the three guide rods on the right side is provided with a threaded hole, and the left side of the connecting plate is provided with a third circular through hole corresponding to the threaded hole. Each of the third circular through holes is provided with a bolt, and each bolt is threadedly connected to its corresponding threaded hole.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By placing two sets of support components symmetrically and mirror-imagely along the longitudinal central axis of the base plate, it is possible to ensure that the bottom of the carbon dioxide fire extinguishing cylinder is subjected to uniform force, thereby enhancing the overall structural balance and load-bearing capacity.

[0021] 2. The first and second support blocks of the support components can effectively support the carbon dioxide fire extinguishing cylinder;

[0022] 3. By using three guide rods in each support component and the first and second springs fitted onto the three guide rods, the two second support blocks can be pushed to the sides when the forklift forks descend. At this time, all six first springs are compressed, and the carbon dioxide fire extinguishing gas cylinder is placed on top of the two first support blocks. After the forklift pulls out the forks, the six first springs rebound, pushing their corresponding second support blocks to the bottom of the carbon dioxide fire extinguishing gas cylinder. The second support blocks and several steel ball rollers provide auxiliary support, while the six second springs are compressed to prevent the connecting plate from directly impacting its corresponding first support block.

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings.

[0031] A single-unit cabinet-type carbon dioxide fire extinguishing device, such as Figures 1-5 As shown, it includes a cabinet 1, a carbon dioxide fire extinguishing cylinder 2, and a support base 3. The support base 3 is fixedly located at the lower end of the interior of the cabinet 1, and the carbon dioxide fire extinguishing cylinder 2 is located at the top of the support base 3.

[0032] The support base 3 includes a base plate 4 and two sets of support components 5. The base plate 4 is fixedly located on the inner bottom wall of the cabinet 1. The two sets of support components 5 are respectively fixed on the top left and right sides of the base plate 4. The two sets of support components 5 are placed symmetrically and mirrorively along the longitudinal central axis of the base plate 4.

[0033] The support assembly 5 located on the right side includes a first support block 511, a second support block 512, a connecting plate 513, and three guide rods 514;

[0034] Both the first support block 511 and the second support block 512 are strip-shaped cuboids. The first support block 511 is fixed longitudinally on the top right side of the base plate 4. The left side of the first support block 511 has three first circular through holes arranged from front to back. Each first circular through hole is equipped with a linear bearing 518. Each linear bearing 518 is connected to the flange of its corresponding first support block 511. Three guide rods 514 are placed horizontally. The three guide rods 514 are slidably inserted into the three first circular through holes and are respectively inserted into the linear bearings 518.

[0035] The second support block 512 is fixed longitudinally on the left side of the three guide rods 514, and the second support block 512 is welded to the three guide rods 514.

[0036] The connecting plate 513 is fixed longitudinally on the right side of the three guide rods 514. The right side of the three guide rods 514 on the right side is provided with threaded holes. The left side of the connecting plate 513 is provided with a third circular through hole corresponding to the threaded hole. Each third circular through hole is provided with a bolt 519. Each bolt 519 is threadedly connected to its corresponding threaded hole. Through the setting of the connecting plate 513 and the second support plate, the three guide rods 514 can slide synchronously.

[0037] Each guide rod 514 is fitted with a first spring 515 at the part between the second support block 512 and the first support block 511, and a second spring 516 at the part between the connecting plate 513 and the first support block 511. The initial state of each first spring 515 is the natural state, and the state of each second spring 516 is the initially compressed state.

[0038] The top and bottom of the second support block 512 are fixedly arrayed with several steel ball rollers 517 from front to back. The steel ball rollers 517 are all plunger-type steel ball rollers. The top of the second support block 512 has several second circular through holes arrayed from front to back. Each second circular through hole contains a steel ball roller 517. Each steel ball roller 517 is connected to the flange of the second support block 512. The steel ball rollers 517 are embedded inside the second support block 512, which increases the strength of the second support block 512 and the steel ball rollers 517.

[0039] The bottom of the lower steel ball rollers 517 abuts against the top of the base plate 4, providing support for the second support block 512 and facilitating the rolling of the lower steel ball rollers 517. The bottom of the upper steel ball rollers 517 is 0.5-0.8mm lower than the top of the first support block 511, leaving a gap to allow the first spring 515 to rebound and push, moving the steel ball rollers 517 to the bottom of the carbon dioxide fire extinguishing cylinder 2. The carbon dioxide fire extinguishing cylinder 2 will sink slightly due to gravity. At this time, the steel ball rollers 517 and the second support plate provide auxiliary support.

[0040] The four sides on the left side of the second support block 512 on the right side and the four sides on the right side of the second support block 512 on the left side are all chamfered. The chamfer is designed to guide the forklift forks when they descend, so that the forks can push the two second support blocks 512 apart to the sides through the chamfer.

[0041] The top of the base plate 4 is flush with the bottom of the opening on the front side of the cabinet 1. The bottom of the base plate 4 has a bent edge 411 at each of the four corners. Several reinforcing plates 412 are fixedly installed at the bottom of the base plate 4.

[0042] Specific implementation process:

[0043] Step 1: The forklift forks carry the carbon dioxide fire extinguishing cylinder 2 into the cabinet 1.

[0044] Step 2: The forklift forks slowly lower the carbon dioxide fire extinguishing cylinder 2. When the forklift forks pass the second support plates on the left and right sides, they pass the chamfer of the second support plates and separate the second support plates to both sides. The two second support plates are displaced along their corresponding three guide rods 514 by several steel ball rollers 517. The first spring 515 on each guide rod 514 is compressed.

[0045] Step 3: Place carbon dioxide fire extinguishing cylinder 2 on top of the two first support plates;

[0046] Step 4: The forklift drives the forks out of cabinet 1. Since the forks are conical, as the forks continue to exit, several first springs 515 slowly reset, pushing their corresponding second support plates to move towards the middle of cabinet 1.

[0047] Step 5: The forklift forks retract from cabinet 1. At this time, several first springs 515 return to their original position, while several second springs 516 are slightly compressed. Several steel ball rollers 517 on the top of the two second support plates are located at the bottom of the carbon dioxide fire extinguishing cylinder 2, which serves as an auxiliary support and enhances the overall structural balance and load-bearing capacity.

[0048] Step 6: The operator secures the steel clamps to the carbon dioxide fire extinguishing cylinder 2.

[0049] Step 7: The carbon dioxide fire extinguishing cylinder 2 has not been used and has reached its shelf life. At this time, the operator inserts the forklift fork between the two second support plates and separates the second support plates to both sides. The two second support plates are displaced along their corresponding three guide rods 514 by several steel ball rollers 517. The first spring 515 on each guide rod 514 is compressed.

[0050] Step 8: The operator loosens the steel hoop of carbon dioxide fire extinguishing cylinder 2, the forklift forks rise, the operator secures carbon dioxide fire extinguishing cylinder 2, the forklift lifts carbon dioxide fire extinguishing cylinder 2, and then exits cabinet 1.

[0051] Step nine: When exiting cabinet 1, the forklift forks rise. Since the second support plate has a chamfer on the side near the forks, as the forks continue to exit, several first springs 515 slowly return to their original position, pushing their corresponding second support plates to move towards the middle position of cabinet 1. The forklift forks exit cabinet 1. At this time, several first springs 515 return to their original position, and several second springs 516 are slightly compressed.

[0052] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
