Description

Technical Field

[0001] This utility model relates to the field of fire protection technology for power distribution cabinets, and in particular to an installation mechanism and a fire extinguishing device for power distribution cabinets. Background Technology

[0002] Distribution boxes play a vital role in people's daily work and life, controlling and managing electricity consumption. However, distribution boxes often pose a fire risk. Especially in the hot summer, the temperature rise of cables often causes weak points in the cable insulation to break down first, even causing a fire. Due to the confined space of distribution boxes, it is difficult to detect and extinguish fires quickly, such as when wiring catches fire, the box door overheats, or large amounts of toxic and harmful gases are produced by burning wiring. This can easily lead to circuit breaker tripping, economic losses, and even personal injury. Therefore, many distribution cabinets are now equipped with automatic thermal aerosol fire extinguishing devices that can extinguish fires from inside the cabinet.

[0003] However, most existing technologies use adhesives such as glue to bond thermal aerosol fire extinguishing devices to the inner wall or top of the distribution cabinet. This method doesn't allow for flexible placement during bonding, sometimes resulting in the device being too far from flammable components, leading to poor extinguishing effectiveness. Furthermore, for larger aerosol fire extinguishing devices, the adhesive's effectiveness decreases over time. If the device sprays aerosol at this point, it might fall from the top or inner wall of the distribution cabinet due to vibration, posing a risk of damaging electrical components. Therefore, we need a dedicated fire extinguishing device mounting bracket. This bracket allows for flexible placement to find the best extinguishing location, while ensuring installation stability and eliminating the risk of the fire extinguishing device falling and damaging electrical components.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1, referring to Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides an installation mechanism, including a lifting frame 1, an installation platform 2 on the top of the lifting frame 1, and a clamping structure 3 on the top of the installation platform 2. Because the electrical components installed in the distribution cabinet may be different and the number of installations may also be different, the installation height of the aerosol fire extinguishing device in the distribution cabinet also needs to be adjusted according to the installation situation of the electrical components in the distribution cabinet. This is so that it can be better close to the possible fire location in order to achieve the best fire extinguishing effect. The lifting frame 1 in the installation mechanism allows the fire extinguishing device to be adjusted in height during installation and installed in the best fire extinguishing position.

[0030] The lifting frame 1 is installed inside the power distribution cabinet. The installation platform 2 has an opening 22 for the fire extinguishing equipment to operate. The fire extinguishing device is installed on the installation platform 2. The aerosol agent in the fire extinguishing device will be sprayed out from the opening 22 to extinguish the fire.

[0031] Furthermore, the lifting frame 1 includes a base frame 11 located at the bottom of the distribution cabinet. A lifting rod 14 that can be raised and lowered within the base frame 11 is provided above the base frame 11. Preferably, the base frame 11 is hollow inside, and the lifting rod 14 is fitted into the inner wall of the base frame 11. A through groove 13 is provided on the outer wall of the base frame 11, penetrating the base frame 11. A locking pin 12 is provided inside the through groove 13. During installation, raising or lowering the lifting rod 14 above the base frame 11 can adjust the height of the lifting rod 14 and the installation platform 2, that is, adjust the height of the fire extinguishing device on the installation platform 2. When the fire extinguishing device is in the optimal position, the locking pin 12 is inserted into the through groove 13 closest to the bottom of the lifting rod 14. The bottom of the lifting rod 14 contacts the upper surface of the locking pin 12, and the locking pin 12 provides support for the lifting rod 14. At this time, the lifting rod 14 can be locked and kept at the optimal height.

[0032] Usage: When installing the fire extinguishing device, the height of the lifting rod 14 and the installation platform 2 can be adjusted by raising or lowering the lifting rod 14 above the base frame 11. That is, the height of the fire extinguishing device on the installation platform 2 can be adjusted to fix the fire extinguishing device on the installation platform 2. The locking pin 12 is inserted into the through groove 13 closest to the bottom of the lifting rod 14 to lock the lifting rod 14 and keep it at the optimal height.

[0033] Example 2, refer to Figures 1-4 This is the second embodiment of the present invention. Unlike the previous embodiment, the mounting platform 2 includes a mounting base plate 21 disposed on the top of the lifting rod 14. An opening 22 is disposed at the bottom of the mounting platform 2, and a mounting groove 25 is provided in the middle of the top of the mounting base plate 21. Figure 3 As shown, the fire extinguishing device is installed on the mounting groove 25. A pad 23 is provided on the top of the mounting groove 25. A nozzle 24 is provided in the middle of the pad 23. The fire extinguishing device sprays fire extinguishing aerosol from the nozzle 24 at the bottom. The opening 22 is set to be large to accommodate more types of fire extinguishing devices. The pad 23 can be replaced with a suitable size according to the size of the fire extinguishing device. The nozzle 24 on the pad 23 should be slightly smaller than the bottom size of the fire extinguishing device.

[0034] Furthermore, the clamping structure 3 includes a stop block 31 disposed on the top of the mounting base plate 21. A fixing frame 32 is disposed on the top of the stop block 31. The stop block 31 is slidably connected to the mounting base plate 21. A locking screw 33 is disposed on the top of the fixing frame 32. The bottom of the locking screw 33 is in contact with the stop block 31. Since the size of the installed fire extinguishing device varies depending on the model, the stop block 31 can slide and adjust its position on the mounting base plate 21 to accommodate fire extinguishing devices of different sizes.

[0035] Furthermore, a fixed clamping plate 34 is provided on the side of the abutment block 31, and a movable clamping plate 35 is provided on the side of the fixed clamping plate 34. The movable clamping plate 35 is slidably connected to the fixed clamping plate 34. A cam 36 is provided on the side of the movable clamping plate 35, and a knob 37 is provided on the top of the cam 36. Rotating the cam 36 can push the movable clamping plate 35 toward the fire extinguishing device to achieve the purpose of clamping the fire extinguishing device.

[0036] Usage process: such as Figure 4As shown, when installing the fire extinguishing device, place the fire extinguishing device on the mounting slot 25, rotate the cam 36 to move the movable clamp 35 to the position closest to the fire extinguishing device, at this time slide the abutment 31 to make the abutment 31 close to the fire extinguishing device, rotate the locking screw 33 to lock the position of the abutment 31, at this time the fire extinguishing device is fixedly clamped above the mounting slot 25. When maintaining the distribution cabinet, it is necessary to disassemble the fire extinguishing device for inspection and maintenance, such as checking whether the airtightness is intact, checking whether the nozzle 42 is blocked by foreign objects, etc. At this time, simply rotate the cam 36 to make the largest diameter end of the cam 36 leave the movable clamp 35, the movable clamp 35 will be released, and the fire extinguishing device can be easily removed.

[0037] Example 3, referring to Figures 1-4 This is the third embodiment of the present invention, which further provides a fire extinguishing device for a power distribution cabinet. It includes an installation mechanism; and a thermal aerosol fire extinguishing device 4, which includes an aerosol generator 41 disposed on the top of the installation platform 2. The aerosol generator 41 has a triggering structure inside, and a spray outlet 42 is opened at the bottom of the aerosol generator 41.

[0038] Furthermore, the aerosol generator 41 is filled with an aerosol generating agent, and its outer wall is equipped with a detection structure 43. This detection structure 43 (such as a thermal wire, temperature sensor, or smoke detector) monitors environmental parameters such as temperature and smoke concentration in real time. Once a fire signal is detected, such as an abnormally high temperature or increased smoke concentration, the detection structure 43 will quickly issue an alarm signal. This alarm signal is transmitted to the control unit of the fire extinguishing device via a control circuit. The control unit analyzes and processes the signal to determine if a preset fire alarm threshold has been reached. If the control unit confirms that the fire signal is genuine and reliable and meets the preset activation conditions, it issues an activation command to activate the aerosol generator 41. Under the action of the initiator, the aerosol generating agent begins to produce a large amount of thermal aerosol extinguishing agent. The sprayed aerosol extinguishing agent quickly covers the fire source, forming a layer of extinguishing aerosol cloud. The solid particles and gaseous components in the aerosol work together to rapidly reduce the temperature around the fire source, while simultaneously absorbing the heat generated by combustion, causing the temperature of the fire source to drop rapidly.
