Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing devices, specifically a cabinet-type heptafluoropropane fire extinguishing device. Background Technology

[0002] Fire extinguishing devices can be classified into various types according to their application scenarios and agent types. Among them, gas fire extinguishing devices are widely used. Cabinet-type heptafluoropropane fire extinguishing devices are a type of gas fire extinguishing device that uses heptafluoropropane as the extinguishing agent and is suitable for enclosed spaces. In addition, there are other types such as water-based and dry powder types, each of which plays a role in different fire scenarios.

[0003] When a fire occurs, the cabinet-type heptafluoropropane fire extinguishing device can be manually activated after confirming that no one is on site, or it can be automatically triggered by the fire alarm system. The heptafluoropropane agent will be released rapidly to inhibit combustion. Before use, it is necessary to ensure that the protected area is sealed to avoid agent leakage affecting the fire extinguishing effect, and personnel must be evacuated to a safe area to prevent suffocation.

[0004] The existing cabinet-type heptafluoropropane fire extinguishing device is installed by tightening and fixing the cylinder body with bolts on the cylinder clamp. However, when it is inspected and removed, the bolts need to be turned multiple times to remove the cylinder body, which makes the cylinder body inconvenient to inspect.

[0005] Therefore, a cabinet-type heptafluoropropane fire extinguishing device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A cabinet-type heptafluoropropane fire extinguishing device of this utility model includes a cabinet body with a placement groove at the bottom. Multiple push plates and baffles are rotatably connected to the side walls of the placement groove. A square plate is rotatably connected to the center of the placement groove. The square plate is located below a pair of baffles. The push plates, baffles, and square plate are all connected to the placement groove via torsion springs. The heptafluoropropane fire extinguishing device body is slidably fitted inside the placement groove. A cabinet door is rotatably connected to the surface of the cabinet body. By adding the square plate and baffles, the gap between the placement groove and the ground can be reduced when installing the heptafluoropropane fire extinguishing device body. This reduces the lifting height when the operator raises the heptafluoropropane fire extinguishing device body, thus saving effort. Subsequently, after entering the placement groove, the pair of push plates will adhere tightly to the heptafluoropropane fire extinguishing device body through the force generated by the compression of the torsion springs, thereby increasing the clamping and fixing of the heptafluoropropane fire extinguishing device body.

[0008] Preferably, an extension plate is slidably connected inside the square plate; both the square plate and the extension plate have pin holes on their side walls; multiple pin holes are provided on the extension plate; a first magnet is fixedly connected to the side wall of the square plate; a second magnet is fixedly connected to the side wall of the cabinet; the second magnet is located below the first magnet; by adding the extension plate and pin holes, the upward resistance can be reduced when the heptafluoropropane fire extinguishing device body is lifted, and at the same time, the second magnet and the first magnet can fix the position of the extension plate by magnetic attraction, thereby increasing the stability of the square plate during use.

[0009] Preferably, a pair of first locking blocks are fixed to the inner wall of the cabinet; a pair of second locking blocks are fixed to the inner wall of the cabinet door; the middle of the first and second locking blocks is arc-shaped; by adding the first and second locking blocks, the upper middle part of the heptafluoropropane fire extinguishing device body can be limited by the combination of the first and second locking blocks when fixing the body of the heptafluoropropane fire extinguishing device, making it more stable during installation.

[0010] Preferably, the cabinet sidewall is provided with ventilation holes; multiple ventilation holes are provided on the cabinet; by increasing the number of ventilation holes, the surrounding airflow can be circulated during the daily operation of the heptafluoropropane fire extinguishing device, thereby increasing the airflow circulation in the surrounding environment and reducing the retention of humid airflow.

[0011] Preferably, the bottom of the placement slot is rotatably connected to rollers; multiple rollers are arranged on the placement slot and located below a pair of baffles; by adding rollers, the movement speed of the heptafluoropropane fire extinguishing device body on the placement slot can be accelerated during the movement of the heptafluoropropane fire extinguishing device body, so that it can quickly enter between the push plates.

[0012] Preferably, a pair of desiccant boxes are fixed to the inner wall of the cabinet; the surface of the desiccant boxes is porous and located at the bottom of the cabinet; by adding desiccant boxes, the humid gas inside the airflow can be eliminated, thereby increasing the dryness of the internal environment of the cabinet.

[0013] The advantages of this utility model are: 1. The cabinet-type heptafluoropropane fire extinguishing device of this utility model reduces the gap between the placement slot and the ground when installing the heptafluoropropane fire extinguishing device body by adding square plates and baffles. This reduces the lifting height when the operator raises the heptafluoropropane fire extinguishing device body, thus saving effort. After entering the placement slot, a pair of push plates will be pressed tightly against the heptafluoropropane fire extinguishing device body by the force generated by the compression of the torsion spring, thereby increasing the clamping and fixing of the heptafluoropropane fire extinguishing device body.

[0014] 2. The cabinet-type heptafluoropropane fire extinguishing device of this utility model reduces the upward resistance when the heptafluoropropane fire extinguishing device body is lifted by adding an extension plate and a pin hole. At the same time, the second magnet and the first magnet can fix the position of the extension plate by magnetic attraction, thereby increasing the stability of the square plate during use.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Specific implementation examples are given below.

[0020] like Figures 1 to 5As shown in the figure, a cabinet-type heptafluoropropane fire extinguishing device according to an embodiment of the present invention includes a cabinet body 1, the bottom of which has a placement groove 11; a plurality of push plates 12 and baffles 13 are rotatably connected to the side wall of the placement groove 11; a square plate 14 is rotatably connected to the middle of the placement groove 11; the square plate 14 is located below a pair of baffles 13; the push plates 12, baffles 13 and square plate 14 are all connected to the placement groove 11 by torsion springs; the heptafluoropropane fire extinguishing device body 15 is slidably fitted inside the placement groove 11; a cabinet door 1 is rotatably connected to the surface of the cabinet body 1. 6. During operation, when installing the heptafluoropropane fire extinguishing device body 15 into the cabinet 1, the operator gradually pushes the heptafluoropropane fire extinguishing device body 15 into the cabinet 1 using the bottle handles on the body. Before entering, the square plate 14 is rotated to move it away from the cabinet 1, and then the pair of baffles 13 are rotated upwards to create space in the middle. This reduces the level difference between the bottom of the cabinet 1 and the ground, making it easier to move the heptafluoropropane fire extinguishing device body 15 into the cabinet 1. The rising height of the heptafluoropropane fire extinguishing device body 15 is increased rapidly and reduced. After the cabinet 1 gradually enters, it reaches the side wall of the push plate 12, causing the pair of push plates 12 to press down and move closer to the inside of the placement slot 11. At this time, the heptafluoropropane fire extinguishing device body 15 is moved into the placement slot 11. Subsequently, when the push plate 12 contacts the heptafluoropropane fire extinguishing device body 15, it will squeeze and push the heptafluoropropane fire extinguishing device body 15, thereby clamping and fixing it by applying force to both sides. Then, the push plate 12 and the baffle 13 are released to allow it to spring back and close the placement slot 11, thus completing the process. For clamping installation, after installation, simply rotate the cabinet door 16 to close the cabinet 1. By adding the square plate 14 and the baffle 13, the gap between the placement slot 11 and the ground can be reduced when installing the heptafluoropropane fire extinguishing device body 15. This reduces the lifting height when the operator raises the heptafluoropropane fire extinguishing device body 15, thus saving effort. After entering the placement slot 11, a pair of push plates 12 will be pressed tightly against the heptafluoropropane fire extinguishing device body 15 by the force generated by the compression of the torsion spring, thereby increasing the clamping and fixing of the heptafluoropropane fire extinguishing device body 15.

[0021] like Figures 1 to 4As shown, an extension plate 2 is slidably connected inside the square plate 14; both the square plate 14 and the extension plate 2 have pin holes 21 on their side walls; multiple pin holes 21 are provided on the extension plate 2; a first magnet 22 is fixedly connected to the side wall of the square plate 14; a second magnet 23 is fixedly connected to the side wall of the cabinet 1; the second magnet 23 is located below the first magnet 22; during operation, after rotating the square plate 14, the first magnet 22 and the second magnet 23 can come into contact, thus fixing the square plate 14. At this time, the square plate 14 will not spring back after being released. Then, the pin inside the pin hole 21 is pulled out, thus unlocking the extension plate 2. Then, the extension plate 2 is pulled out of the square plate 14, and the operation stops after the extension plate 2 contacts the ground. Then, insert the pin into the corresponding pin hole 21 to fix the extension plate 2. At this time, when the body 15 of the heptafluoropropane fire extinguishing device is moved, it can be gradually raised by the slope formed by the extension plate 2 and the square plate 14, thereby reducing the resistance when the body 15 of the heptafluoropropane fire extinguishing device is raised. After use, pull out the pin, place the extension plate 2 into the square plate 14, and then fix it by inserting the pin into the pin hole 21. By adding the extension plate 2 and the pin hole 21, the upward resistance can be reduced when the body 15 of the heptafluoropropane fire extinguishing device is raised. At the same time, the second magnet 23 and the first magnet 22 can fix the position of the extension plate 2 by magnetic attraction, thereby increasing the stability of the square plate 14 during use.

[0022] like Figures 2 to 5 As shown, a pair of first locking blocks 3 are fixed to the inner wall of the cabinet 1; a pair of second locking blocks 31 are fixed to the inner wall of the cabinet door 16; the middle of the first locking blocks 3 and the second locking blocks 31 are both arc-shaped; during operation, after the heptafluoropropane fire extinguishing device body 15 is placed inside the cabinet 1, it first contacts the first locking blocks 3. At this time, the first locking blocks 3 will restrict the heptafluoropropane fire extinguishing device body 15, causing it to stop in the middle of the placement slot 11. Then, when the cabinet door 16 is closed, the second locking blocks 31 will contact the heptafluoropropane fire extinguishing device body 15. After contact, they will form a two-sided clamp with the first locking blocks 3, thereby limiting its position; by adding the first locking blocks 3 and the second locking blocks 31, the upper middle part of the heptafluoropropane fire extinguishing device body 15 can be limited by the combination of the first locking blocks 3 and the second locking blocks 31 when fixing the heptafluoropropane fire extinguishing device body 15, making it more stable during installation.

[0023] like Figures 1 to 2As shown, ventilation holes 4 are provided on the side wall of the cabinet 1; multiple ventilation holes 4 are provided on the cabinet 1; during operation, when the heptafluoropropane fire extinguishing device body 15 is in daily use, the airflow from the outside will enter the cabinet 1 through the ventilation holes 4, and the airflow inside the cabinet 1 will be driven, thereby exchanging with the outside through the ventilation holes 4, increasing the airflow inside the cabinet 1; by adding ventilation holes 4, the surrounding airflow can be circulated during the daily operation of the heptafluoropropane fire extinguishing device body 15, increasing the airflow circulation of the surrounding environment, thereby reducing the retention of humid airflow.

[0024] like Figure 3 As shown, a roller 5 is rotatably connected to the bottom of the placement slot 11; multiple rollers 5 are arranged on the placement slot 11 and located below a pair of baffles 13; during operation, when the heptafluoropropane fire extinguishing device body 15 passes under the baffles 13, it will contact the roller 5. At this time, the heptafluoropropane fire extinguishing device body 15 will drive the roller 5 to rotate during movement. During rotation, the friction between the heptafluoropropane fire extinguishing device body 15 and the placement slot 11 will be reduced, thereby accelerating the movement speed; by adding rollers 5, the movement speed of the heptafluoropropane fire extinguishing device body 15 on the placement slot 11 can be accelerated during movement, so that it can quickly enter between the push plates 12.

[0025] like Figure 2 As shown, a pair of desiccant boxes 6 are fixed to the inner wall of the cabinet 1; the surface of the desiccant box 6 is porous and located below the cabinet 1; during operation, after the heptafluoropropane fire extinguishing device body 15 is installed and in use, when humid gas appears in the airflow inside the cabinet 1, the device gradually sinks and then comes into contact with the desiccant box 6. Upon contact, the device is gradually absorbed by the desiccant inside the desiccant box 6, thus eliminating the moisture inside the airflow; by adding the desiccant box 6, the humid gas inside the airflow can be eliminated, thereby increasing the dryness of the internal environment of the cabinet 1.

[0026] Working principle: When installing the heptafluoropropane fire extinguishing device body 15 into the cabinet 1, the operator gradually pushes the heptafluoropropane fire extinguishing device body 15 into the cabinet 1 using the lugs on the body. Before entering, the square plate 14 is rotated to move it out of the cabinet 1, and then a pair of baffles 13 are rotated upwards to create space in the middle. This reduces the level difference between the bottom of the cabinet 1 and the ground, allowing the heptafluoropropane fire extinguishing device body 15 to be moved. Upon entering the cabinet 1, the movement is accelerated, reducing the rising height of the heptafluoropropane fire extinguishing device body 15. As it gradually enters the cabinet 1, it reaches the side wall of the push plate 12, pressing it down to bring it closer to the placement slot 11. Then, the heptafluoropropane fire extinguishing device body 15 is moved into the placement slot 11. Subsequently, when the push plate 12 contacts the heptafluoropropane fire extinguishing device body 15, it squeezes and pushes it, clamping and fixing it by applying force to both sides. Then, the push plate 12 and the baffle 13 are released to allow it to enter. The springback mechanism closes the placement slot 11, allowing for clamping and installation. After installation, the cabinet door 16 is rotated to close the cabinet body 1. After rotating the square plate 14, the first magnet 22 and the second magnet 23 come into contact, fixing the square plate 14 in place. When the square plate 14 is released, it will not spring back. Then, the pin inside the pin hole 21 is pulled out, unlocking the extension plate 2. The extension plate 2 is then pulled out of the square plate 14 and stopped when it contacts the ground. Finally, the pin is inserted into the corresponding pin hole 21. After fixing the extension plate 2, the body 15 of the heptafluoropropane fire extinguishing device can be moved gradually by using the slope formed by the extension plate 2 and the square plate 14, thereby reducing the resistance when lifting the body 15. After use, pull out the pin, place the extension plate 2 inside the square plate 14, and then fix it by inserting the pin into the pin hole 21. After the body 15 of the heptafluoropropane fire extinguishing device is placed inside the cabinet 1, it first contacts the first locking block 3. At this time, the first locking block 3 will lock the body 15 of the heptafluoropropane fire extinguishing device. The device is restricted to remain in the middle of the placement slot 11. When the cabinet door 16 is closed, the second locking block 31 will contact the body 15 of the heptafluoropropane fire extinguishing device. After contact, it will form a double clamp with the first locking block 3, thereby limiting its movement. During normal use, the airflow from the outside will enter the cabinet 1 through the ventilation hole 4. At this time, the airflow inside the cabinet 1 will be driven, thereby exchanging with the outside through the ventilation hole 4, increasing the airflow inside the cabinet 1. When the body 15 of the heptafluoropropane fire extinguishing device passes under the baffle 13, it will contact the roller 5. At this time, the body 15 of the heptafluoropropane fire extinguishing device will drive the roller 5 to rotate during movement. The rotation will reduce the friction between the body 15 of the heptafluoropropane fire extinguishing device and the placement slot 11, thereby speeding up the movement.During use after the heptafluoropropane fire extinguishing device body 15 is installed, when humid gas appears in the airflow inside the cabinet 1, the device gradually sinks and then comes into contact with the desiccant box 6. Upon contact, the desiccant inside the desiccant box 6 gradually absorbs the moisture, thus eliminating the moisture in the airflow.
