Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing equipment, and in particular to a heptafluoropropane fire extinguishing device. Background Technology

[0002] Heptafluoropropane (HFC-227ea / FM200) is a clean gaseous fire extinguishing agent that primarily uses chemical extinguishing methods, while also possessing physical extinguishing properties. In large, complex areas, and situations requiring high extinguishing efficiency, dual-cylinder configurations of heptafluoropropane fire suppression systems are typically used.

[0003] Currently, Chinese patent with authorization announcement number "CN205994933U" discloses a novel heptafluoropropane fire extinguishing device, including a fire extinguishing agent cylinder rack, a driving gas cylinder group, a fire extinguishing agent delivery pipeline, a manifold, and a fire extinguishing agent cylinder group. The fire extinguishing agent cylinder rack is provided with a fire extinguishing agent cylinder group clamp on its inner side. The fire extinguishing agent cylinder group is connected to the fire extinguishing agent cylinder group rack through the fire extinguishing agent cylinder group clamp. The top of the fire extinguishing agent cylinder group is connected to a fire extinguishing agent cylinder group container valve.

[0004] In existing technologies, clamps are generally used to limit the movement of extinguishing agent cylinder groups. However, due to the "Ω"-shaped structure of the clamps, sufficient clearance must be maintained between the two groups of extinguishing agent cylinders, and also between the extinguishing agent cylinder groups and the extinguishing agent cylinder group rack. This increases the overall size of the fire extinguishing equipment. Furthermore, because dual-cylinder group configurations are typically used, the dual-cylinder groups generally have large capacities, resulting in large diameters for each extinguishing agent cylinder group. This makes direct installation of the clamps onto the extinguishing agent cylinder group rack difficult. The installation process requires reaching deep between the two cylinder groups for secure fixing, making it difficult and time-consuming. When using two clamps to secure the extinguishing agent cylinder groups, the clamps are fixed on both sides, meaning the clamp inside the cylinder group frame is only securely connected to the rear side, resulting in insecure fixing of the cylinder groups. Furthermore, after disassembling the clamps, they need to be removed and properly positioned; otherwise, the weight of the cylinder groups makes it easy to step on and damage the clamps during transport. Utility Model Content

[0005] The purpose of this invention is to provide a heptafluoropropane fire extinguishing device, which has the advantages of conveniently fixing two sets of fire extinguisher cylinders, saving space, simple operation, and saving time.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A heptafluoropropane fire extinguishing device includes a cylinder rack, two sets of fire extinguisher cylinders, and a manifold. The two sets of fire extinguisher cylinders are placed vertically on either side of the cylinder rack. The manifold is fixed at the top of the cylinder rack, and both sets of fire extinguisher cylinders are connected to the manifold.

[0008] The bottle rack is a square frame, and bottle group limiting components are fixedly provided at the upper and lower ends of the internal part of the bottle rack.

[0009] The bottle group limiting assembly includes a first arc-shaped plate, a second arc-shaped plate, a guide block, a guide rod, a guide cylinder, a spring, a stop block, and two first nuts. The first and second arc-shaped plates are both plates with semi-circular cross-sections. The second arc-shaped plate is located to the right of the first arc-shaped plate. The guide block is fixedly located on the front side of the right side of the first arc-shaped plate and the front side of the left side of the second arc-shaped plate. The front side of the guide block has a first circular through hole. The guide rod is slidably inserted into the first circular through hole. The stop block is fixedly located on the front side of the guide rod. The guide cylinder is fixedly located longitudinally and horizontally on the inner rear side wall of the bottle group frame. The rear side of the guide rod is inserted into the guide cylinder. The guide rod is a threaded rod. The two first nuts are respectively threaded to the rear side of the guide rod. The spring is sleeved on the guide rod and is located between the guide block and the two first nuts.

[0010] The distance from the top to the bottom of the stop block is four-fifths of the distance from the left side to the right side of the guide block. When replacing the fire extinguisher cylinder assembly, rotate the stop block to change it from a horizontal to a vertical position, which can reduce the interference of the stop block with the fire extinguisher cylinder assembly.

[0011] The front side of the guide cylinder is provided with a cross-shaped groove, the depth of which is two-thirds of the distance from the front side to the rear side of the guide cylinder. The upper right corner and the lower left corner of the front side of the guide cylinder are provided with clearance grooves, both of which are connected to the cross-shaped groove. The depth of each clearance groove is one-third of the distance from the front side to the rear side of the guide cylinder. The left side wall and the rear side of the right side wall of the guide rod are both fixed with sliders, and the two sliders are respectively slidably inserted into the left and right sides of the cross-shaped groove.

[0012] The preferred solution is as follows:

[0013] Preferably, the guide block is a square block, the left side of the rear side of the guide block is fixedly connected to the front side of the right side of the first arc-shaped plate, and the right side of the rear side of the guide block is fixedly connected to the front side of the right side of the second arc-shaped plate.

[0014] Preferably, the guide rod is a threaded rod.

[0015] Preferably, the abutment is a block with an isosceles trapezoidal cross-section and its lower base is located on the front side. The front side of the abutment has a trapezoidal opening, and the rear side wall inside the trapezoidal opening of the abutment has a second circular through hole. The front side of the guide rod is inserted into the second circular through hole. The rear side of the top of the abutment has a fourth circular through hole that passes through the abutment and the guide rod. The top of the abutment has a circular relief groove, and the bottom of the abutment has a regular hexagonal relief groove. An internal hexagonal bolt is inserted into the fourth circular through hole, and the bolt head of the internal hexagonal bolt is located in the circular relief groove. A second nut is provided in the regular hexagonal relief groove, and the internal hexagonal bolt and the second nut are threadedly connected and fixed.

[0016] Preferably, a reinforcing rod is fixedly provided on the front side inside the trapezoidal opening of the abutment block.

[0017] Preferably, the left and rear side walls of the first arc-shaped plate and the right and rear side walls of the second arc-shaped plate are fixedly connected to the bottle assembly rack.

[0018] Preferably, the upper left and lower right corners of the inner rear sidewall of the trapezoidal opening of the abutment block are provided with third circular through holes, and the front side of the guide block is provided with threaded holes corresponding to the two third circular through holes. Each third circular through hole is provided with an external hexagonal bolt, and each external hexagonal bolt is threadedly connected to its corresponding threaded hole.

[0019] Preferably, the distance from the top to the bottom of the abutment block is four-fifths of the distance from the left side to the right side of the guide block.

[0020] In summary, this utility model, through the setting of the bottle group limiting component, enables the replacement of fire extinguisher bottle groups by simply unscrewing the two external hex bolts, then grasping the reinforcing rod, pulling the guide rod outward and rotating it 90 degrees, and then releasing the reinforcing rod. The spring rebounds, thus releasing the limiting effect on the fire extinguisher bottle group. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] 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.

[0034] A heptafluoropropane fire extinguishing device, such as Figures 1-9 As shown, it includes a bottle rack 1, two sets of fire extinguisher bottle groups 2, and a manifold 3. The two sets of fire extinguisher bottle groups 2 are placed vertically on the left and right sides inside the bottle rack 1. The manifold 3 is fixed at the top of the bottle rack 1. Both sets of fire extinguisher bottle groups 2 are connected to the manifold 3.

[0035] The bottle rack 1 is a square frame, and bottle rack limiting components 4 are fixedly installed at the upper and lower ends of the interior of the bottle rack 1.

[0036] The bottle assembly limiting component 4 includes a first arc-shaped plate 411, a second arc-shaped plate 412, a guide block 413, a guide rod 414, a guide cylinder 415, a spring 416, a stop block 417, and two first nuts 418. Both the first arc-shaped plate 411 and the second arc-shaped plate 412 are plates with semi-circular cross-sections. The second arc-shaped plate 412 is located to the right of the first arc-shaped plate 411. The guide block 413 is fixedly located at the front side of the right side of the first arc-shaped plate 411 and the front side of the left side of the second arc-shaped plate 412. The front side of the guide block 413... The first circular through hole 419 is provided in the part, the guide rod 414 is slidably inserted into the first circular through hole 419, the abutment block 417 is fixedly located on the front side of the guide rod 414, the guide cylinder 415 is fixedly located on the inner rear side wall of the bottle assembly rack 1 in a longitudinal horizontal shape, the rear side of the guide rod 414 is inserted into the guide cylinder 415, the guide rod 414 is a threaded rod, two first nuts 418 are respectively threaded to the rear side of the guide rod 414, and a spring 416 is sleeved on the guide rod 414, the spring 416 is located between the guide block 413 and the two first nuts 418;

[0037] A cross-shaped groove 420 is provided on the front side of the guide cylinder 415. The depth of the cross-shaped groove 420 is two-thirds of the distance from the front side to the rear side of the guide cylinder 415. Relief grooves 421 are provided at the upper right and lower left corners of the front side of the guide cylinder 415. Both relief grooves 421 are connected to the cross-shaped groove 420. The depth of each relief groove 421 is one-third of the distance from the front side to the rear side of the guide cylinder 415. A slider 4 is fixedly provided on the rear side of both the left and right side walls of the guide rod 414. 22. The two sliders 422 slide and insert into the left and right sides of the cross-shaped groove 420 respectively. The guide rod 414 moves forward, and the two sliders 422 reach their corresponding clearance grooves 421 respectively. The guide rod 414 is rotated, and the two horizontally placed sliders 422 are placed vertically. Then, the spring 416 rebounds, driving the guide rod 414 to move backward. The two sliders 422 are inserted into the upper and lower sides of their corresponding cross-shaped grooves 420 respectively, completing the limiting of the guide rod 414.

[0038] The guide block 413 is a square block, which can ensure that the first circular through hole 419 of the guide block 413 can fully guide and limit the guide rod 414. The left side of the rear side of the guide block 413 is fixedly connected to the front side of the right side of the first arc plate 411, and the right side of the rear side of the guide block 413 is fixedly connected to the front side of the right side of the second arc plate 412. The guide rod 414 is located between the first arc plate 411 and the second arc plate 412, so that the gap between the first arc plate 411 and the second arc plate 412 can be fully utilized.

[0039] The abutment block 417 is an isosceles trapezoidal block with its lower base located on the front side. The inclined sides of the abutment block 417 can be used to abut against the two sets of fire extinguisher bottle groups 2, thereby completing the limiting. The front side of the abutment block 417 has a trapezoidal opening. The rear side wall inside the trapezoidal opening of the abutment block 417 has a second circular through hole. The front side of the guide rod 414 is inserted into the second circular through hole. The rear side of the top of the abutment block 417 has a fourth circular through hole that passes through the abutment block 417 and the guide rod 414. The top of the abutment block 417 has a circular relief groove. The bottom of the abutment block 417 has a regular hexagonal relief groove. The fourth circular through hole is filled with an internal hexagonal bolt 423. The bolt head of the internal hexagonal bolt 423 is located in the circular relief groove. The regular hexagonal relief groove is filled with a second nut 424. The internal hexagonal bolt 423 and the second nut 424 are threadedly connected and fixed.

[0040] A reinforcing rod 425 is fixedly provided on the front side inside the trapezoidal opening of the abutment block 417. The reinforcing rod 425 can increase the strength of the two sides of the abutment block 417, and at the same time, it also provides a place for the operator to hold the rotating guide rod 414.

[0041] The left and rear sides of the first arc-shaped plate 411 and the right and rear sides of the second arc-shaped plate 412 are fixedly connected to the bottle assembly frame 1 by welding. The fixation by the side walls on both sides can further strengthen the fixation and limiting of the two sets of fire extinguisher bottle assemblies 2.

[0042] Since the spring 416 is elastic, in order to further fix the stop block 417, the upper left and lower right corners of the rear side wall inside the trapezoidal opening of the stop block 417 are provided with third circular through holes. The front side of the guide block 413 is provided with threaded holes corresponding to the two third circular through holes. Each third circular through hole is provided with an external hexagonal bolt 426, and each external hexagonal bolt 426 is threadedly connected to its corresponding threaded hole. Since the external hexagonal bolt 426 is on the front side of the stop block 417, it is convenient for the operator to work.

[0043] Specific implementation process:

[0044] Step 1: Two sets of fire extinguisher bottle groups 2 are installed on the bottle group rack 1. Replace the fire extinguisher bottle group 2. At this time, the blocks 417 of the limit components 4 of the two sets of bottle groups are placed horizontally.

[0045] Step 2: The operator loosens and removes both external hex bolts 426 of the two sets of bottle group limiting components 4;

[0046] Step 3: The operator first rotates the stop block 417 of the bottle group limiting component 4 located below;

[0047] Step 4: The operator holds the reinforcing rod 425 and pulls it forward. The spring 416 is compressed. Since the reinforcing rod 425 is fixedly connected to the guide rod 414, the guide rod 414 drives the two sliders 422 on its rear side to move forward.

[0048] When the rear sides of the two sliders 422 are located in the clearance groove 421, the rear side of the guide rod 414 is still located in the guide cylinder 415. The abutment block 417 is rotated counterclockwise, and the abutment block 417 drives the guide rod 414 to rotate counterclockwise. The guide rod 414 drives the two sliders 422 to rotate counterclockwise, and the two sliders 422 change from horizontal to vertical. The two sliders 422 abut against the side wall of the cross-shaped groove 420 of their corresponding guide cylinder 415. At this time, the abutment block 417 is vertical. The operator releases the reinforcing rod 425, the spring 416 rebounds, and drives the guide rod 414 to move backward. The two sliders 422 slide and insert into the upper and lower sides of the cross-shaped groove 420 respectively.

[0049] Block 417 restricts the contact between the two sets of fire extinguisher cylinder groups 2;

[0050] Step 5: Repeat step 4 to rotate the stop block 417 of the upper bottle group limiting component 4;

[0051] Step Six: The operator removes the two sets of fire extinguisher cylinders 2 from cylinder rack 1;

[0052] The operator then placed the two new sets of fire extinguisher cylinders 2 on the cylinder rack 1;

[0053] Step 7: The operator first rotates the stop block 417 of the upper bottle group limiting component 4;

[0054] Step 8: The operator holds the reinforcing rod 425 and pulls it forward. The spring 416 is compressed. Since the reinforcing rod 425 is fixedly connected to the guide rod 414, the guide rod 414 drives the two sliders 422 on its rear side to move forward.

[0055] When the rear sides of the two sliders 422 are located in the clearance groove 421, the rear side of the guide rod 414 is still located in the guide cylinder 415. Rotating the abutment block 417 clockwise causes the guide rod 414 to rotate clockwise, which in turn causes the two sliders 422 to rotate clockwise. The two sliders 422 change from a vertical position to a horizontal position. The two sliders 422 abut against the side wall of the cross-shaped groove 420 of their respective guide cylinders 415. At this time, the abutment block 417 is horizontal. When the operator releases the reinforcing rod 425, the spring 416 rebounds, causing the guide rod 414 to move backward. The two sliders 422 slide and insert into the left and right sides of the cross-shaped groove 420, respectively.

[0056] At this point, the inclined side of the abutment block 417 abuts against the upper side wall of the two sets of fire extinguisher bottle groups 2, completing the initial positioning of the two sets of fire extinguisher bottle groups 2.

[0057] The operator then inserts two external hex bolts 426 into the two third circular through holes of the abutment block 417, and then threads the two external hex bolts 426 into their corresponding threaded holes to complete the limit;

[0058] Step 9: Repeat step 8 to rotate the stop block 417 of the bottle group limiting component 4 located below;

[0059] Step 10: Replace the two sets of fire extinguisher cylinders 2 on cylinder rack 1.

[0060] 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.
