Description

Technical Field

[0001] This utility model belongs to the technical field of fire extinguishing devices, and in particular relates to a wall-mounted automatic fire extinguishing device. Background Technology

[0002] Automatic fire extinguishing systems are devices that can automatically detect fires, trigger alarms, and release extinguishing agents, extinguishing or controlling initial fires without direct manual operation. Automatic fire extinguishing systems have a wide range of applications, primarily in industrial, civil, and special locations.

[0003] A search revealed an automatic fire extinguishing device with publication number CN214596944U published on the Chinese Patent website. This automatic fire extinguishing device solves the technical problem that existing automatic fire extinguishing devices cannot meet the fire protection requirements of areas where electrical equipment is stored. However, it has some defects and shortcomings that need to be improved: (1) Most existing automatic fire extinguishing devices are suspended on the ceiling for use. Once installed, their position is basically fixed. When it is necessary to adjust the installation position of the automatic fire extinguishing device, it is often necessary to climb to a high place with a ladder, remove it, and reinstall it. This is not only cumbersome and inconvenient, but also poses a safety hazard; (2) Due to the structural design of some existing automatic fire extinguishing devices, the extinguishing agent can often only be sprayed in one direction when extinguishing a fire, and it is difficult to fully cover the area around the fire point, which can easily create dead corners and reduce the efficiency of fire extinguishing. Therefore, in view of the above problems, the wall-mounted automatic fire extinguishing device provided by this utility model is of great significance. Utility Model Content

[0004] This utility model provides a wall-mounted automatic fire extinguishing device. By inserting a locking block into the top of the fixed plate on the inner wall of the movable frame, the heat insulation chamber along with the entire automatic fire extinguishing device can be suspended and fixed on the movable frame. When the installation position of the automatic fire extinguishing device needs to be adjusted, the movable frame can drive the slider to move vertically along the slide groove. When the slider moves, it can drive the slide rods on both sides to move vertically along the guide grooves, thereby quickly adjusting the vertical position of the automatic fire extinguishing device as needed. After adjustment, the first nut can be threaded onto each slide rod and tightened, so that the vertical position of the automatic fire extinguishing device can be fixed by the cooperation between the slide rod and the first nut. At the same time, the locking block can drive the heat insulation chamber along with the entire automatic fire extinguishing device to move horizontally along the fixed plate, thereby quickly adjusting the vertical position as needed. Compared to existing automatic fire extinguishing devices, the horizontal position of the automatic fire extinguishing device eliminates the need to climb to a high place with a ladder to dismantle and reinstall it, making it more convenient and faster while also avoiding safety hazards. The fire detector transmits control signals to the control valve, opening it and allowing the extinguishing agent stored in the tank to be sprayed through nozzles. After being sprayed through the nozzles, the extinguishing agent enters the diffusion chamber through the feed inlet and is then sprayed towards the fire point through various diffusion ports, achieving automatic fire extinguishing. When the extinguishing agent enters the diffusion chamber through the nozzles and feed inlet, the multiple diffusion ports evenly distributed along the arc-shaped end face of the front of the diffusion chamber allow the extinguishing agent to be sprayed in a fan-shaped direction, effectively expanding the spray range and ensuring full coverage of the area around the fire point. This avoids blind spots that could affect fire extinguishing efficiency, thus solving the problems in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a wall-mounted automatic fire extinguishing device, comprising a fixed frame and a movable frame. The top and bottom of the fixed frame are L-shaped and have mounting holes, and the front face of the fixed frame has a sliding groove. The left and right ends of the movable frame are L-shaped, and fixed plates are fixedly connected between their inner walls. A slider is fixedly connected to the rear face of the movable frame, and sliding rods are fixedly connected to both sides of the slider. The sliding rods have external threads and are threaded with a first nut that mates with them. A pair of guide plates are fixedly connected to the rear face of the fixed frame. The guide plates are symmetrically distributed on the left and right sides of the chute, and guide grooves are opened on their surfaces. A heat insulation chamber is provided on the front side of the movable frame. A locking block is fixedly connected to the rear end face of the heat insulation chamber. A chamber cover and a fire detector are respectively installed on the top and bottom of the heat insulation chamber. A through hole is opened at the bottom of the heat insulation chamber. A storage tank is installed inside the heat insulation chamber. The storage tank is cylindrical. A feed inlet and a nozzle are respectively provided on its top and bottom. A control valve is installed on the nozzle. Its bottom end passes through the through hole at the bottom of the heat insulation chamber and is equipped with a diffusion mechanism.

[0007] The diffusion mechanism includes a diffusion chamber, the top of which is provided with a feed inlet, and the front end face of the diffusion chamber is provided with a plurality of diffusion ports.

[0008] Furthermore, the slide groove is rectangular, and its width is equal to the thickness of the slider. The guide groove is rectangular, and its width is equal to the diameter of the slide rod. The center of each guide groove corresponds one-to-one with the center of each slide rod.

[0009] Furthermore, the card block is L-shaped, and its inner wall is provided with an anti-slip pad, the surface of which is provided with a herringbone anti-slip pattern.

[0010] Furthermore, a protrusion is fixedly connected to the bottom of the compartment cover. The cross-section of the protrusion and the insulation compartment are both rectangular, and the length and width of the protrusion are equal to the length and width of the inner wall of the insulation compartment, respectively.

[0011] Furthermore, a limiting ring is provided inside the heat insulation chamber. The limiting ring is circular, and its inner diameter corresponds to the outer diameter of the storage tank. Connecting blocks are fixedly connected between the outer wall of the limiting ring and the four inner walls of the heat insulation chamber.

[0012] Furthermore, the front end face of the diffusion chamber is arc-shaped, and both the diffusion port and the feed inlet are connected to the inner cavity of the diffusion chamber, and the included angle between two adjacent diffusion ports is equal.

[0013] Furthermore, the inner diameter of the nozzle is equal to the outer diameter of the feed inlet, and positioning seats are fixedly connected to the bottom sidewalls on both sides of the nozzle. Positioning holes are provided on the positioning seats. A pair of positioning rods are fixedly connected to the top of the diffusion chamber. The rods are provided with external threads and are threadedly connected to a second nut that matches them. The rod diameter is equal to the diameter of the positioning hole, and the center of each positioning rod corresponds one-to-one with the center of each positioning hole.

[0014] The present invention has the following advantages over the prior art:

[0015] (1) The wall-mounted installation method is adopted, which makes it easy to adjust the installation position: By inserting the card block into the top of the fixed plate on the inner wall of the movable frame, the heat insulation chamber and the entire automatic fire extinguishing device can be suspended and fixed on the movable frame. When it is necessary to adjust the installation position of the automatic fire extinguishing device, the movable frame can drive the slider to move vertically along the slide groove. When the slider moves, it can drive the slide rods on both sides to move vertically along the guide groove, so that the vertical position of the automatic fire extinguishing device can be quickly adjusted as needed. After the adjustment is completed, the first nut can be threaded onto each slide rod and tightened so that the vertical position of the automatic fire extinguishing device can be fixed through the mutual cooperation between the slide rod and the first nut. At the same time, the card block can drive the heat insulation chamber and the entire automatic fire extinguishing device to move horizontally along the fixed plate, so that the horizontal position of the automatic fire extinguishing device can be quickly adjusted as needed. Compared with the existing automatic fire extinguishing device, there is no need to climb to a high place with a ladder and then dismantle and reinstall it. It is not only more convenient and faster, but also avoids safety hazards.

[0016] (2) The extinguishing agent has a wide coverage area and is not prone to dead spots: When a fire occurs, the fire detector can transmit the control signal to the control valve and open the control valve. At this time, the extinguishing agent stored in the storage tank can be sprayed out through the nozzle. After the extinguishing agent is sprayed out through the nozzle, it can enter the diffusion chamber through the feed port and spray towards the fire point through each diffusion port to achieve automatic fire extinguishing. When the extinguishing agent enters the diffusion chamber through the nozzle and feed port, it can be sprayed out in a fan-shaped direction through multiple diffusion ports evenly distributed along the arc-shaped end face of the front end of the diffusion chamber, thereby effectively expanding the spray range of the extinguishing agent so that it can fully cover the area around the fire point and avoid affecting the fire extinguishing efficiency due to the existence of dead spots.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figure 1-9 As shown, this utility model discloses a wall-mounted automatic fire extinguishing device, comprising a fixed frame 1 and a movable frame 2. The top and bottom of the fixed frame 1 are L-shaped and have mounting holes 3. The front end of the fixed frame 1 has a sliding groove 4. Screws or other fasteners can be inserted into the mounting holes 3 to fix the fixed frame 1 to a designated position on the wall. The left and right ends of the movable frame 2 are L-shaped, and a fixing plate 5 is fixedly connected between their inner walls. A slider 6 is fixedly connected to the rear end of the movable frame 2. Sliding rods 7 are fixedly connected to both sides of the slider 6. The rods 7 have external threads and are threaded together. A first nut 8 is provided to cooperate with it. A pair of guide plates 9 are fixedly connected to the rear end face of the fixed frame 1. The guide plates 9 are symmetrically distributed on the left and right sides of the slide groove 4. Guide grooves 10 are opened on their surfaces. A heat insulation chamber 11 is provided on the front side of the movable frame 2. A locking block 12 is fixedly connected to the rear end face of the heat insulation chamber 11. A chamber cover 13 and a fire detector 14 are respectively installed on the top and bottom of the heat insulation chamber 11. A through hole 15 is opened at the bottom of the heat insulation chamber 11. A storage tank 16 is installed inside the heat insulation chamber 11. The storage tank 16 is used to store fire extinguishing agents (such as dry powder, aerosol, etc.). The storage tank 16 is cylindrical, with an inlet 17 at the top and a nozzle 18 at the bottom. A control valve 19 is installed on the nozzle 18, and its bottom end passes through a through-hole 15 at the bottom of the insulated chamber 11 and is equipped with a diffusion mechanism. The control valve 19 is a solenoid valve and is electrically connected to a fire detector 14 via a wire. The fire detector 14 can detect the surrounding temperature, smoke, or flames in real time. When a fire occurs, it transmits a control signal to the control valve 19, opening it. At this time, the extinguishing agent stored in the storage tank 16 can be sprayed out through the nozzle 18. To facilitate automatic fire suppression, the fire detector 14 can be an existing product on the market, such as the DG822 heat-sensitive fire detector, which has an effective detection angle of 120° and a detection distance of 0.5 to 3 meters. The distance between the bottom of the fire detector 14 and the top of the diffusion chamber 20 is not less than 6 cm, and the central axis of the fire detector 14 coincides with the central axis of the diffusion chamber 20 to avoid the diffusion chamber 20 from obstructing the detection line of sight, so as to ensure that the control valve 19 is triggered within 5 seconds after the fire occurs. The specific structure and working principle of the fire detector 14 are all publicly available technologies and will not be described in detail here.

[0033] The diffusion mechanism includes a diffusion chamber 20, with a feed inlet 21 at the top and several diffusion ports 22 on the front face of the diffusion chamber 20. When the extinguishing agent is sprayed out through the nozzle 18, it can enter the diffusion chamber 20 through the feed inlet 21 and be sprayed toward the fire point through each diffusion port 22 to extinguish the fire.

[0034] The slide groove 4 is rectangular, and its width corresponds to the thickness of the slider 6. The guide groove 10 is rectangular, and its width corresponds to the diameter of the slide rod 7. The center of each guide groove 10 corresponds to the center of each slide rod 7. The movable frame 2 can drive the slider 6 to move vertically along the slide groove 4. When the slider 6 moves, it can drive the slide rods 7 on both sides to move vertically along the guide groove 10 respectively. Thus, the vertical position of the automatic fire extinguishing device can be quickly adjusted as needed. After the adjustment is completed, the first nut 8 can be threaded onto each slide rod 7 and tightened so that the vertical position of the automatic fire extinguishing device can be fixed through the mutual cooperation between the slide rod 7 and the first nut 8.

[0035] The locking block 12 is L-shaped, and its inner wall is provided with an anti-slip pad 23. The surface of the anti-slip pad 23 is provided with herringbone anti-slip texture. The locking block 12 can be inserted into the top of the fixing plate 5 so that the heat insulation chamber 11 and the entire automatic fire extinguishing device can be suspended and fixed on the movable frame 2. The locking block 12 can drive the heat insulation chamber 11 and the entire automatic fire extinguishing device to move horizontally in a straight line along the fixing plate 5, so that the horizontal position of the automatic fire extinguishing device can be quickly adjusted as needed. The anti-slip pad 23 can be made of elastic materials such as rubber and fixed by adhesives. When the automatic fire extinguishing device is suspended and installed, the anti-slip texture on the surface of the anti-slip pad 23 can increase the friction between the locking block 12 and the fixing plate 5 to play an anti-slip role, thereby preventing the automatic fire extinguishing device from slipping and shifting after installation.

[0036] The bottom of the cover 13 is fixedly connected with a protrusion 24. The cross-section of the protrusion 24 and the heat insulation chamber 11 is rectangular, and the length and width of the protrusion 24 correspond to the length and width of the inner wall of the heat insulation chamber 11, respectively. When the cover 13 is placed on top of the heat insulation chamber 11, the protrusion 24 can be inserted into and fit against the inner wall of the heat insulation chamber 11 so that the cover 13 can be fixed by insertion. Both the cover 13 and the heat insulation chamber 11 are made of high temperature resistant materials and can cover the storage tank 16 to play a role in heat insulation, thereby preventing the storage tank 16 from deforming or even exploding due to high temperature. When the extinguishing agent in the storage tank 16 is used up, the cover 13 can be opened and the extinguishing agent in the storage tank 16 can be replenished through the feed port 17. Specifically, the insulated compartment 11 adopts a double-layer structure, with an outer layer of 1.2mm thick 304 stainless steel plate and an inner layer of 5mm thick alumina ceramic plate, with 20mm thick aluminum silicate insulation cotton filling between the two layers; the overall high temperature resistance range is -20℃ to 500℃, and it can withstand the high temperature radiation within 30 minutes of the initial stage of a fire, so as to ensure that the storage tank 16 (withstanding temperature ≤120℃) has no risk of deformation.

[0037] The insulation chamber 11 is equipped with a limiting ring 25. The limiting ring 25 is circular, and its inner diameter corresponds to the outer diameter of the storage tank 16. The outer wall of the limiting ring 25 is fixedly connected to the four inner walls of the insulation chamber 11. The limiting ring 25 can be sleeved on the outside of the storage tank 16 to play a limiting role, thereby preventing the storage tank 16 from tilting and ensuring that the storage tank 16 is always placed vertically.

[0038] The front end of the diffusion chamber 20 is arc-shaped. Both the diffusion port 22 and the feed inlet 21 are connected to the inner cavity of the diffusion chamber 20, and the included angle between two adjacent diffusion ports 22 is equal. When the extinguishing agent enters the diffusion chamber 20 through the nozzle 18 and the feed inlet 21, the extinguishing agent can be sprayed out in a fan-shaped direction through multiple diffusion ports 22 that are equidistantly distributed along the arc-shaped end face of the front end of the diffusion chamber 20. This can effectively expand the spray range of the extinguishing agent, so that it can fully cover the area around the fire point and avoid the impact of dead corners on the extinguishing efficiency. Specifically, the arc radius of the front end face of the diffusion chamber 20 is 80mm, and six diffusion ports 22 are evenly opened along the arc. The included angle between adjacent diffusion ports 22 is 30°, and the diameter of each diffusion port 22 is 8mm. After diffusion, the extinguishing agent forms a 180° fan-shaped spray range with an effective coverage radius of not less than 1.5 meters to ensure that there are no dead corners in the extinguishing.

[0039] The inner diameter of the nozzle 18 is equal to the outer diameter of the feed inlet 21. Positioning seats 27 are fixedly connected to the bottom sidewalls of both sides of the nozzle 18. Positioning holes 28 are provided on the positioning seats 27. A pair of positioning rods 29 are fixedly connected to the top of the diffusion chamber 20. The rods 29 have external threads and are threaded to a matching second nut 30. The rod diameter is equal to the diameter of the positioning hole 28. The center of each positioning rod 29 corresponds one-to-one with the center of each positioning hole 28. Each positioning rod 29 can be aligned and pass through the corresponding positioning hole 28. At this time, the second nut 30 is threaded... Connected to and tightened to each positioning rod 29, the diffusion chamber 20, together with the entire diffusion mechanism, can be fixed to the bottom of the nozzle 18 through the mutual cooperation between the positioning rod 29 and the second nut 30. After the diffusion mechanism is installed and fixed, the guide port 21 can be inserted and fitted against the inner wall of the nozzle 18 to ensure the sealing performance between the diffusion mechanism and the nozzle 18 and prevent the extinguishing agent from leaking out through the gaps. After long-term use, the diffusion mechanism can be removed from the bottom of the nozzle 18 by unscrewing the second nut 30 so that the inside of the diffusion chamber 20 and each diffusion port 22 can be cleaned regularly to avoid clogging.

[0040] All standard parts used in the application documents can be purchased from the market. All components in this application documents can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

[0041] The working principle of this utility model is as follows:

[0042] In use, the locking block 12 can be inserted into the top of the fixing plate 5 on the inner wall of the movable frame 2 to suspend and fix the heat insulation chamber 11 together with the entire automatic fire extinguishing device on the movable frame 2. When it is necessary to adjust the installation position of the automatic fire extinguishing device, the movable frame 2 can drive the slider 6 to move vertically along the slide groove 4. When the slider 6 moves, it can drive the slide rods 7 on both sides to move vertically along the guide groove 10, so that the vertical position of the automatic fire extinguishing device can be quickly adjusted as needed. After the adjustment is completed, the first nut 8 can be threaded onto each slide rod 7 and tightened so that the vertical position of the automatic fire extinguishing device can be fixed by the cooperation between the slide rods 7 and the first nut 8. At the same time, the locking block 12 can drive the heat insulation chamber 11 together with the entire automatic fire extinguishing device to move horizontally along the fixing plate 5, so that the automatic fire extinguishing device can be quickly adjusted as needed. Compared to existing automatic fire extinguishing devices, the horizontal position of this device eliminates the need to climb to a high place with a ladder to dismantle and reinstall it, making it more convenient and faster while also avoiding safety hazards. When a fire occurs, the fire detector 14 can transmit a control signal to the control valve 19, opening the control valve 19. At this time, the extinguishing agent stored in the storage tank 16 can be sprayed out through the nozzle 18. After the extinguishing agent is sprayed out through the nozzle 18, it can enter the diffusion chamber 20 through the feed inlet 21 and be sprayed towards the fire point through various diffusion ports 22 to achieve automatic fire extinguishing. When the extinguishing agent enters the diffusion chamber 20 through the nozzle 18 and feed inlet 21, the multiple diffusion ports 22 evenly distributed along the front arc-shaped end face of the diffusion chamber 20 can make the extinguishing agent spray out in a fan-shaped direction, thereby effectively expanding the spray range of the extinguishing agent and enabling it to fully cover the area around the fire point, avoiding the impact of dead corners on fire extinguishing efficiency.
