Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, specifically to a perfluorohexanone storage tank mounting bracket for an automatic fire extinguishing box for an electrical cabinet. Background Technology

[0002] Perfluorohexanone (PFH) is an important alternative to halon fire extinguishing agents; it is a fluorinated ketone compound. While liquid at room temperature, PFH readily vaporizes and exists as a gas, allowing for safe storage and transportation in ordinary containers over a wide temperature range under normal pressure. PFH primarily achieves its extinguishing effect through endothermic reaction. Furthermore, due to its high extinguishing concentration of 4-6%, PFH offers a relatively high safety margin and is safer for human use. Therefore, PFH is widely used as an extinguishing agent in fire extinguishers.

[0003] Chinese Utility Model Patent Publication No. CN 222900078 U discloses an automatic perfluorohexanone fire extinguishing device. The specification of this device states that when an external sensor detects a fire, a first and second solenoid valve open. Compressed nitrogen from the compressed nitrogen storage tank is then delivered to the Venturi tube via a first delivery pipe. This creates a negative pressure in the Venturi tube, drawing liquid perfluorohexanone from the perfluorohexanone storage tank into the Venturi tube via a second delivery pipe. This liquid, along with the nitrogen, is then delivered to the nozzle via a hose, thus achieving automatic fire extinguishing. However, this automatic perfluorohexanone fire extinguishing device lacks a mounting bracket for the perfluorohexanone storage tank, preventing its detachable installation and making subsequent maintenance and replacement inconvenient, resulting in poor practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a mounting bracket for the perfluorohexanone storage tank of the automatic fire extinguishing box for electrical cabinets, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a mounting bracket for a perfluorohexanone storage tank of an automatic fire extinguishing box for an electrical cabinet, comprising an electrical cabinet body and a perfluorohexanone storage tank body. Four sets of lifting rings are fixedly installed on the top of the electrical cabinet body. A support frame is provided between two sets of lifting rings on the top of the electrical cabinet body. Extension frames are provided at both ends of the support frame near the lifting rings. A support plate is fixedly installed at the center of one end of the support frame near the perfluorohexanone storage tank body. A second sliding groove is symmetrically formed on one end of the support plate near the perfluorohexanone storage tank body. A groove is formed on the inner side of the second sliding groove away from the perfluorohexanone storage tank body. A fixing groove is formed below the groove. An installation ring is provided on the outer surface of the perfluorohexanone storage tank body. Slider blocks are fixedly installed at both ends of the installation ring near the second sliding groove. A fitting part is provided at one end of the support plate near the perfluorohexanone storage tank body.

[0006] Preferably, the extension frame has a through-hole at one end near the lifting ring. The connecting hole has the same cross-section as the lifting ring and can pass through the lifting ring and fit the bottom of the lifting ring.

[0007] By using the above technical solution, and by setting the cross-section of the connecting hole to be the same as that of the lifting ring, the compatibility between the extension frame and the lifting ring is ensured, so that the extension frame and the lifting ring are tightly connected, and the loosening of the extension frame due to size mismatch is avoided.

[0008] Preferably, the support frame has a sliding groove at both ends near the extension frame that is slidably connected to the extension frame, the extension frame has a number of sets of limiting holes at equal intervals at the end away from the appliance cabinet body, and the support frame has a limiting pin on the side away from the appliance cabinet body.

[0009] Through the above technical solution, the overall length of the support frame can be adjusted by sliding the extension frame and the slide groove, making it suitable for electrical cabinets of different specifications and improving the applicability of the mounting bracket.

[0010] Preferably, the radius of the limiting pin is the same as the radius of the limiting hole, and the limiting pin can be inserted into the limiting hole.

[0011] With the above technical solution, by setting the radius of the limiting pin to be the same as the radius of the limiting hole and allowing the limiting pin to be inserted into the limiting hole, after the length adjustment is completed, the operator can manually insert the limiting pin into the limiting hole to achieve quick locking of the extension frame and quick adjustment of the support frame length.

[0012] Preferably, the slider and the groove are slidably connected, the cross-section of the slider is the same as the cross-section of the groove, and the slider can be inserted into the fixed groove.

[0013] With the above technical solution, when the perfluorohexanone storage tank body is placed on top of the support frame, the design of sliding connection between the slider and the groove can be used to initially fix the perfluorohexanone storage tank body. Then, when the mounting ring is moved to the groove, the mounting ring is pushed towards the support plate. Finally, the slider on the mounting ring is inserted into the fixing groove, which can quickly fix the perfluorohexanone storage tank body without the need for external tools, thereby improving the installation efficiency.

[0014] Preferably, the cross-section of the bonding portion is in the shape of a "︵" and the bonding portion is tightly bonded to the body of the perfluorohexanone storage tank.

[0015] The above technical solution, by setting the cross-section of the fitting part to be "︵" shaped, facilitates the fitting part to fit the circular outer surface of the perfluorohexanone storage tank body, increases the surface area of ​​both, and disperses the pressure on the perfluorohexanone storage tank body and the support plate, thereby reducing surface wear of the perfluorohexanone storage tank body. Furthermore, by tightly fitting the fitting part to the perfluorohexanone storage tank body, it can play a buffering role when the perfluorohexanone storage tank body is impacted, reducing the risk of damage to the perfluorohexanone storage tank body due to collision.

[0016] Preferably, the perfluorohexanone storage tank body is provided in two identical sets, and the two sets of perfluorohexanone storage tank bodies are symmetrically distributed on the top of the support frame.

[0017] The above technical solution improves the fire extinguishing effect by setting up two sets of perfluorohexanone storage tanks. When one set of perfluorohexanone storage tanks fails, the other set can serve as a backup, thus enhancing the fire extinguishing protection capability of the electrical cabinet.

[0018] Compared with the prior art, this utility model provides a mounting bracket for a perfluorohexanone storage tank of an automatic fire extinguishing box for electrical cabinets, which has the following beneficial effects:

[0019] 1. The perfluorohexanone storage tank mounting bracket of the automatic fire extinguishing box of the electrical cabinet uses a sliding connection design between the slider and the groove to initially fix the perfluorohexanone storage tank body. Then, when the mounting ring is moved to the groove, the mounting ring is pushed towards the support plate. Finally, the slider on the mounting ring is inserted into the fixing groove, which can quickly fix the perfluorohexanone storage tank body without the use of external tools, thereby improving the installation efficiency. It also facilitates the quick disassembly of the perfluorohexanone storage tank body, making it convenient for later maintenance and replacement.

[0020] 2. The perfluorohexanone storage tank mounting bracket for the automatic fire extinguishing box of the electrical cabinet allows users to adjust the overall length of the support frame by sliding the extension frame through the slide rail, according to the width of the electrical cabinet body. This is suitable for electrical cabinets of different specifications. By setting the radius of the limit pin to be the same as the radius of the limit hole, and ensuring that the limit pin can be inserted into the limit hole, after the length adjustment is completed, the operator can manually insert the limit pin into the limit hole to quickly lock the extension frame, thus facilitating rapid adjustment of the support frame length. Subsequently, by setting the cross-section of the connection hole to be the same as that of the lifting ring, the compatibility of the extension frame and the lifting ring connection is ensured, making the extension frame and the lifting ring tightly connected and preventing the extension frame from loosening due to size mismatch.

[0029] 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 protection scope of the present utility model.

[0030] Example 1: As Figure 1-7 As shown, the present invention provides a perfluorohexanone storage tank mounting bracket for an automatic fire extinguishing box for an electrical cabinet, comprising an electrical cabinet body 1 and a perfluorohexanone storage tank body 9. Four sets of lifting rings 2 are fixedly installed on the top of the electrical cabinet body 1. A support frame 3 is provided between two sets of lifting rings 2 on the side of the top of the electrical cabinet body 1. Extension frames 4 are provided at both ends of the support frame 3 near the lifting rings 2. A support plate 10 is fixedly installed at the center of the end of the support frame 3 near the perfluorohexanone storage tank body 9. A second sliding groove 11 is symmetrically opened at the end of the support plate 10 near the perfluorohexanone storage tank body 9. A groove 12 is opened at the inner side of the second sliding groove 11 away from the perfluorohexanone storage tank body 9. A fixing groove 13 is opened below the groove 12. An installation ring 14 is provided on the outer surface of the perfluorohexanone storage tank body 9. A slider 15 is fixedly installed at both ends of the installation ring 14 near the second sliding groove 11. A fitting part 16 is provided at the end of the support plate 10 near the perfluorohexanone storage tank body 9.

[0031] Specifically, the extension frame 4 has a through-hole 8 at one end near the lifting ring 2. The cross-section of the connecting hole 8 is the same as that of the lifting ring 2, and the connecting hole 8 can pass through the lifting ring 2 and fits the bottom of the lifting ring 2. The advantage is that by setting the cross-section of the connecting hole 8 to be the same as that of the lifting ring 2, the compatibility of the connection between the extension frame 4 and the lifting ring 2 is ensured, so that the extension frame 4 and the lifting ring 2 are tightly connected, avoiding loosening of the extension frame 4 due to size mismatch.

[0032] Specifically, the support frame 3 has sliding grooves 5 at both ends near the extension frame 4, which are slidably connected to the extension frame 4. The extension frame 4 has several sets of limiting holes 6 at equal intervals at its end away from the appliance cabinet body 1. A limiting pin 7 is provided on the side of the support frame 3 away from the appliance cabinet body 1. The advantage is that the sliding connection between the extension frame 4 and the sliding grooves 5 allows for adjustment of the overall length of the support frame 3, making it suitable for appliance cabinets of different specifications and improving the applicability of the mounting bracket.

[0033] Specifically, the radius of the limiting pin 7 is the same as the radius of the limiting hole 6, and the limiting pin 7 can be inserted into the limiting hole 6. The advantage is that by setting the radius of the limiting pin 7 to be the same as the radius of the limiting hole 6 and allowing the limiting pin 7 to be inserted into the limiting hole 6, after the length adjustment is completed, the operator can manually insert the limiting pin 7 into the limiting hole 6 to quickly lock the extension frame 4 and quickly adjust the length of the support frame 3.

[0034] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, slider 15 and groove 11 are slidably connected. The cross-section of slider 15 is the same as that of groove 12, and slider 15 can be inserted into fixing groove 13. The advantage is that when the perfluorohexanone storage tank body 9 is placed on top of support frame 3, the sliding connection between slider 15 and groove 11 can be used to initially fix the perfluorohexanone storage tank body 9. Then, when the mounting ring 14 is moved to groove 12, the mounting ring 14 is pushed towards support plate 10. Finally, slider 15 on mounting ring 14 is inserted into fixing groove 13, which can quickly fix the perfluorohexanone storage tank body 9 without the need for external tools, thereby improving installation efficiency.

[0036] Specifically, the cross-section of the fitting part 16 is shaped like a "︵", and the fitting part 16 is tightly fitted to the perfluorohexanone storage tank body 9. The advantage is that by setting the cross-section of the fitting part 16 to be shaped like a "︵", it is easy for the fitting part 16 to adapt to the circular outer surface of the perfluorohexanone storage tank body 9, increasing the contact area between the two, dispersing the pressure on the perfluorohexanone storage tank body 9 and the support plate 10, thereby reducing surface wear on the perfluorohexanone storage tank body 9. Furthermore, the tight fit between the fitting part 16 and the perfluorohexanone storage tank body 9 can act as a buffer when the perfluorohexanone storage tank body 9 is subjected to impact, reducing the risk of damage to the perfluorohexanone storage tank body 9 due to collision.

[0037] Specifically, two identical sets of perfluorohexanone storage tank bodies 9 are provided, symmetrically distributed on top of the support frame 3. The advantage is that by providing two sets of perfluorohexanone storage tank bodies 9, the fire extinguishing effect can be improved. When one set of perfluorohexanone storage tank bodies 9 fails, the other set can serve as a backup, thus enhancing the fire extinguishing capability of the electrical cabinet body 1.

[0038] Working Principle: During use, the user can adjust the overall length of the support frame 3 by sliding the extension frame 4 and the slide groove 5 according to the width of the electrical cabinet body 1. This is suitable for electrical cabinets of different specifications. By setting the radius of the limit pin 7 to be the same as the radius of the limit hole 6, and ensuring that the limit pin 7 can be inserted into the limit hole 6, the operator can manually insert the limit pin 7 into the limit hole 6 after length adjustment to quickly lock the extension frame 4 and achieve rapid length adjustment of the support frame 3. Subsequently, by setting the cross-section of the connecting hole 8 to be the same as that of the lifting ring 2, the compatibility of the connection between the extension frame 4 and the lifting ring 2 is ensured, making the extension frame 4 and the lifting ring 2 tightly connected and preventing the extension frame 4 from loosening due to size mismatch. After the support frame 3 is installed, the two sets of perfluorohexanone storage tank bodies 9 can be placed on top of the support frame 3. The sliding connection between the slider 15 and the slide groove 11 achieves the initial connection of the perfluorohexanone storage tank bodies 9. After fixing, when the mounting ring 14 is moved to the groove 12, the mounting ring 14 is pushed towards the support plate 10. Finally, the slider 15 on the mounting ring 14 is inserted into the fixing groove 13, which can quickly fix the perfluorohexanone storage tank body 9 without the use of external tools, thereby improving installation efficiency. It also facilitates the quick disassembly of the perfluorohexanone storage tank body 9, making it easier for later maintenance and replacement. By setting the cross-section of the fitting part 16 to be in the shape of "︵", it is easy for the fitting part 16 to fit the circular outer surface of the perfluorohexanone storage tank body 9, increasing the contact area between the two, dispersing the pressure on the perfluorohexanone storage tank body 9 and the support plate 10, thereby reducing the surface wear of the perfluorohexanone storage tank body 9. Furthermore, the tight fit between the fitting part 16 and the perfluorohexanone storage tank body 9 can play a buffering role when the perfluorohexanone storage tank body 9 is subjected to impact, reducing the risk of damage to the perfluorohexanone storage tank body 9 due to collision.
