Description

Technical Field

[0001] The utility model belongs to the technical field of fire extinguishing devices, and particularly relates to a suspended heptafluoropropane fire extinguishing cabinet. Background Art

[0002] A suspended heptafluoropropane gas fire extinguishing cabinet installs a heptafluoropropane fire extinguisher above the cabinet body to protect the electrical components in the lower half of the cabinet body. The heptafluoropropane fire extinguisher is a clean gas chemical fire extinguishing agent that mainly uses chemical fire extinguishing and has a physical fire extinguishing effect. Since heptafluoropropane does not contain chlorine or bromine, it will not damage the atmospheric ozone layer, is colorless, odorless, low-toxic, non-conductive, does not pollute the protected object, and will not damage property and precision facilities. Therefore, it is generally used in important places such as computer rooms.

[0003] The outer shell of the heptafluoropropane fire extinguisher is generally made of non-transparent material, and the heptafluoropropane fire extinguisher is installed in the upper half of the cabinet body. Therefore, maintenance personnel cannot directly observe whether the gas remaining in the heptafluoropropane fire extinguisher is sufficient, which reduces the maintenance efficiency of the maintenance personnel.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model

[0005] In order to solve the above problems, the purpose of the utility model is to provide a suspended heptafluoropropane fire extinguishing cabinet.

[0006] To achieve the above purpose, the utility model provides a suspended heptafluoropropane fire extinguishing cabinet, which includes a cabinet body. A plurality of springs are fixedly connected to the inner top wall of the cabinet body. The bottom ends of the plurality of springs are commonly fixedly connected to a top plate. A vertical block is fixedly connected to the center of the top of the top plate. A control part is arranged above the vertical block. An installation plate is arranged below the top plate. The bottom of the installation plate is detachably connected with a heptafluoropropane fire extinguisher.

[0007] In one example, the control part includes a switch fixedly connected to the inner top wall of the cabinet body. The switch is located directly above the vertical block, and there is a gap between the switch and the vertical block. A warning light is fixedly connected to the upper half of the side wall of the cabinet body. The warning light is electrically connected to the switch.

[0008] In one example, side plates are fixedly connected to opposite sides of the top plate. A lead screw is rotatably connected between the two side plates. The lead screw rotatably passes through the vertical block. A motor is fixedly connected to one side of the side plate away from the lead screw. The output end of the motor is in transmission connection with the lead screw. A linkage part is arranged between the lead screw and the installation plate.

[0009] In one example, the linkage part includes two avoidance channels formed at the top of the top plate. Two sections of threads with opposite helix directions are provided on the outer peripheral surface of the lead screw, and screw blocks are threadedly connected to both sections of the threads on the outer peripheral surface of the lead screw. One side of each screw block is hinged with a connecting rod. The connecting rod passes through the corresponding avoidance channel, and the bottom end of the connecting rod is hinged to the side wall of the mounting plate.

[0010] In one example, the screw block is arranged in a quadrangular prism shape, and the bottom surface of the screw block is in fit with the top surface of the top plate.

[0011] In one example, the top surface of the vertical block is located above the top surface of the side plate.

[0012] In one example, a plurality of sliding sleeves are fixedly connected to the top of the top plate, a plurality of sliding rods are fixedly connected to the inner top wall of the cabinet body, and the lower half of the sliding rod is slidably connected to the corresponding sliding sleeve.

[0013] The suspended heptafluoropropane fire extinguishing cabinet proposed by the present utility model can bring the following beneficial effects:

[0014] 1. There is a gap between the vertical block and the switch in the initial state. When the gas capacity in the heptafluoropropane fire extinguisher is insufficient, the weight of the heptafluoropropane fire extinguisher decreases, the pulling force on the spring decreases, and the spring can contract under the action of its own restoring force, thereby driving the top plate, the vertical block and the heptafluoropropane fire extinguisher to move upward. The vertical block contacts and presses the switch, thereby starting the warning light to remind the maintenance personnel that the heptafluoropropane fire extinguisher in the cabinet needs to be inflated, improving the maintenance efficiency;

[0015] 2. When removing the heptafluoropropane fire extinguisher for inflation, the maintenance personnel can start the motor to work, driving the heptafluoropropane fire extinguisher to move downward. The maintenance personnel can directly contact the heptafluoropropane fire extinguisher. Therefore, the heptafluoropropane fire extinguishers at some higher positions do not need to rely on climbing tools, facilitating the maintenance work of the maintenance personnel.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality" means two or more unless otherwise specifically defined.

[0024] In the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection, or a communication connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the internal communication of two elements or the interaction relationship between two elements.

[0025] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to terms such as "one solution", "some solutions", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the solution or example are included in at least one solution or example of the present utility model. In this specification, the schematic expressions of the above terms do not necessarily refer to the same solution or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more solutions or examples.

[0026] As Figures 1 to 3 shown, an embodiment of the present utility model provides a suspended heptafluoropropane fire extinguishing cabinet, which includes a cabinet body 1. A plurality of springs 2 are fixedly connected to the inner top wall of the cabinet body 1. The bottom ends of the plurality of springs 2 are commonly fixedly connected to a top plate 3. A vertical block 4 is fixedly connected to the center of the top of the top plate 3. A control part 5 is arranged above the vertical block 4. An installation plate 6 is arranged below the top plate 3. A heptafluoropropane fire extinguisher 7 is detachably connected to the bottom of the installation plate 6.

[0027] The number of the springs 2 is four, and the four springs 2 are respectively located near the four corners of the top of the top plate 3. The heptafluoropropane fire extinguisher 7 has the largest weight when it is full, and its weight is smaller when the remaining gas in the heptafluoropropane fire extinguisher 7 is insufficient. Therefore, the remaining gas volume inside it can be judged by the weight of the heptafluoropropane fire extinguisher 7.

[0028] Specifically, the control part 5 includes a switch 51 fixedly connected to the inner top wall of the cabinet body 1. The switch 51 is located directly above the vertical block 4, and there is a gap between the switch 51 and the vertical block 4. A warning lamp 52 is fixedly connected to the upper half of the side wall of the cabinet body 1. The warning lamp 52 is electrically connected to the switch 51.

[0029] In the initial state, the gas inside the heptafluoropropane fire extinguisher 7 is sufficient. Therefore, the pulling force of the heptafluoropropane fire extinguisher 7 on the spring 2 is large, and the heights of the top plate 3 and the vertical block 4 are low. At this time, there is a gap between the switch 51 and the vertical block 4. When the gas content in the heptafluoropropane fire extinguisher 7 decreases, the pulling force of the heptafluoropropane fire extinguisher 7 on the spring 2 gradually decreases. Therefore, the spring 2 gradually contracts, driving the top plate 3, the heptafluoropropane fire extinguisher 7, and the vertical block 4 to gradually rise. When the remaining gas content in the heptafluoropropane fire extinguisher 7 is insufficient and needs to be replenished, the vertical block 4 moves to press the switch 51, and the switch 51 is turned on to control the warning lamp 52 to work. The warning lamp 52 emits red light, reminding the maintenance personnel that the heptafluoropropane fire extinguisher 7 in the cabinet body 1 needs to be inflated, improving the maintenance efficiency.

[0030] Specifically, side plates 8 are fixedly connected to both opposite sides of the top plate 3. A lead screw 9 is rotatably connected between the two side plates 8. The lead screw 9 rotatably penetrates through the vertical block 4. A motor 10 is fixedly connected to one side of the side plate 8 away from the lead screw 9. The output end of the motor 10 is in transmission connection with the lead screw 9. A linkage part 11 is arranged between the lead screw 9 and the mounting plate 6. The linkage part 11 includes two avoidance channels 12 formed on the top of the top plate 3. Two sections of threads with opposite helix directions are provided on the outer peripheral surface of the lead screw 9. Threaded blocks 13 are threadedly connected to both sections of the threads on the outer peripheral surface of the lead screw 9. One side of the threaded block 13 is hinged with a connecting rod 14. The connecting rod 14 passes through the corresponding avoidance channel 12, and the bottom end of the connecting rod 14 is hinged to the side wall of the mounting plate 6.

[0031] When inflating the heptafluoropropane fire extinguisher 7, the heptafluoropropane fire extinguisher 7 needs to be removed. At this time, if the height of the maintenance personnel is difficult to directly reach the heptafluoropropane fire extinguisher 7, the maintenance personnel can start the motor 10. The motor 10 works to drive the lead screw 9 to rotate. The rotation of the lead screw 9 drives the two threaded blocks 13 to move in opposite directions. The threaded blocks 13 drive the connecting rods 14 to move. The connecting rods 14 drive the mounting plate 6 to move vertically downward, thereby driving the heptafluoropropane fire extinguisher 7 to move downward, so that the maintenance personnel can conveniently remove the heptafluoropropane fire extinguisher 7 without using climbing tools.

[0032] Specifically, the heptafluoropropane fire extinguisher 7 and the mounting plate 6 are fixedly connected by bolts.

[0033] Specifically, the threaded block 13 is arranged in a prismatic shape, and the bottom surface of the threaded block 13 is in contact with the top surface of the top plate 3. Therefore, when the lead screw 9 rotates, the threaded block 13 will not rotate with the lead screw 9, but can only move horizontally.

[0034] Specifically, the top surface of the vertical block 4 is above the top surface of the side plate 8. Therefore, when the top plate 3 moves upward, the vertical block 4 contacts the switch 51 first, rather than the side plate 8 contacting the inner top wall of the cabinet body 1 to hinder the movement of the top plate 3.

[0035] Specifically, a plurality of sliding sleeves 15 are fixedly connected to the top of the top plate 3. A plurality of sliding rods 16 are fixedly connected to the inner top wall of the cabinet body 1. The lower half of the sliding rod 16 is slidably connected in the corresponding sliding sleeve 15.

[0036] The sliding rod 16 can only slide vertically in the sliding sleeve 15. Therefore, the top plate 3 can only move vertically, preventing the spring 2 from being bent after a long time, resulting in the situation where the vertical block 4 and the switch 51 cannot be aligned.

[0037] Working principle: In the initial state, the gas in the heptafluoropropane fire extinguisher 7 is sufficient. Therefore, the pulling force of the heptafluoropropane fire extinguisher 7 on the spring 2 is relatively large, the height of the top plate 3 and the vertical block 4 is relatively low, and there is a gap between the switch 51 and the vertical block 4 at this time. When the gas content in the heptafluoropropane fire extinguisher 7 decreases, the pulling force of the heptafluoropropane fire extinguisher 7 on the spring 2 gradually decreases. Therefore, the spring 2 gradually contracts, driving the top plate 3, the heptafluoropropane fire extinguisher 7 and the vertical block 4 to gradually rise. When the remaining gas content in the heptafluoropropane fire extinguisher 7 is insufficient and needs to be replenished, the vertical block 4 moves to press the switch 51, and the switch 51 is turned on to control the warning light 52 to work. The warning light 52 emits red light, reminding the maintenance personnel that the heptafluoropropane fire extinguisher 7 in the cabinet 1 needs to be inflated, improving the maintenance efficiency.

[0038] When inflating the heptafluoropropane fire extinguisher 7, if the height of the maintenance personnel is difficult to directly contact the heptafluoropropane fire extinguisher 7, the maintenance personnel can start the motor 10. The motor 10 works to drive the lead screw 9 to rotate. The rotation of the lead screw 9 drives the two nuts 13 to move in opposite directions. The nut 13 drives the connecting rod 14 to move, and the connecting rod 14 drives the mounting plate 6 to move vertically downward, thereby driving the heptafluoropropane fire extinguisher 7 to move downward. The maintenance personnel remove the heptafluoropropane fire extinguisher 7 for inflation. After inflation is completed, the heptafluoropropane fire extinguisher 7 is fixed on the mounting plate 6 again, and then the motor 10 is reversed to make the heptafluoropropane fire extinguisher 7 return to its initial height.
