Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing equipment, in particular to an automatic fire extinguishing device for commercial kitchens. Background Art

[0002] There are many types of fire extinguishing devices, including water mist spraying and carbon dioxide spraying. When a fire occurs in the kitchen, the fire is generally extinguished through the installation of automatic fire extinguishing devices.

[0003] A commercial kitchen automatic fire extinguishing device currently in use, after searching, is found, for example, in a Chinese patent document with the authorization publication number CN216022764U, which discloses an automatic fire extinguishing device for kitchen use, comprising a box body and a connecting pipe, wherein the two bottom ends of the connecting pipe are respectively movably plugged with the left and right sides of the top of the box body, and the left and right sides of the bottom wall of the box body are fixedly installed with telescopic rods, and the top ends of the two telescopic rods are fixedly connected with a placement plate, and two fire extinguishing bottles are arranged inside the placement plate. The automatic fire extinguishing device for kitchen use, by twisting the lower gear, the upper gear rotates, and then the two first bevel gears rotate, driving the two second bevel gears meshing with the surfaces of the two first bevel gears to rotate, so that the two sealing sleeves rotate, and at the same time, the lower gear rotates and drives the rear toothed plate to move upward, so that the placement plate is raised, so that the two fire extinguishing bottles are plugged with the two bottom ends of the connecting pipe, and the two sealing sleeves are threadedly installed on the top ends of the two fire extinguishing bottles, so as to improve the sealing performance of the fire extinguishing bottles when they are installed, thereby facilitating the installation and use of the fire extinguishing bottles.

[0004] Although the above patents solve the problems in the above-mentioned background technology, they still have the following shortcomings: 1. The device only relies on the placement groove to realize the positioning and fixation of the fire extinguisher bottle, and the applicability of this positioning method is not good. Therefore, when placing fire extinguisher bottles of different sizes, it is easy to cause the fire extinguisher bottle to shake, which is not conducive to subsequent fire extinguishing operations; 2. The device does not have the function of directional adjustment of the nozzle, which makes the nozzle unable to track the fire source point, which leads to accidental spraying of non-fire source areas, increases the waste of fire extinguishing agent, and reduces the fire extinguishing efficiency of the device.

[0005] In summary, the utility model solves the problems in the above-mentioned background technology by designing an automatic fire extinguishing device for commercial kitchens. Utility Model Content

[0031] In this embodiment, the arrangement of the nozzle 5 and the hose is mainly to facilitate the connection between the fire extinguishing tank 601 and the nozzle 402, thereby ensuring the subsequent fire extinguishing operation.

[0032] Specifically, the inner surface of the bracket 401 is rotatably connected to the outer surface of the nozzle 402 through an electric rotating shaft, and the electric rotating seat 4 and the thermal imaging camera 403 are electrically connected to the controller 2 through wires respectively;

[0033] In this embodiment, the controller 2 is mainly used to control the electric rotating seat 4 and the electric rotating shaft, so that the electric rotating seat 4 drives the nozzle 402 to rotate, and the thermal imaging camera 403 can identify the fire source point, thereby achieving the effect of the nozzle 402 tracking the fire source point.

[0034] Specifically, the temperature detector 301, the smoke detector 302 and the solenoid valve 603 are electrically connected to the controller 2 through wires respectively;

[0035] In this embodiment, the temperature detector 301 and the smoke detector 302 can monitor the surrounding environment in real time. Once a fire occurs, the controller 2 will control the solenoid valve 603 to open, so that the fire extinguishing material in the fire extinguishing tank 601 can be sprayed out from the nozzle 402, thereby achieving the purpose of extinguishing the fire.

[0036] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The positioning clamping mechanism 7 includes a No. 1 clamping plate 701 and a movable plate 702. The No. 1 clamping plate 701 is fixedly mounted on the front inner wall of the installation bin 6. The movable plate 702 is arranged on the inner rear side of the installation bin 6, and an electric push rod 703 is fixedly mounted on the left end thereof. A supporting compression spring 704 and a fixed sleeve 705 are fixedly mounted on the right side of the movable plate 702. A telescopic cylinder 706 is arranged at the front end of the fixed sleeve 705, and a No. 2 clamping plate 707 is fixedly arranged at the front end of the telescopic cylinder 706.

[0037] Specifically, the fixed end of the electric push rod 703 passes through the rear inner wall of the installation bin 6 and extends outward, the support compression spring 704 and the fixed sleeve 705 are symmetrically arranged about the front surface of the movable plate 702, the rear end of the telescopic cylinder 706 slides through the front end surface of the fixed sleeve 705 and extends inward, the front end of the support compression spring 704 is fixed to the rear surface of the second clamping plate 707, the bottom surfaces of the first clamping plate 701 and the second clamping plate 707 are not in contact with the bottom inner wall of the installation bin 6, and the facing side surfaces of the first clamping plate 701 and the second clamping plate 707 are provided with rubber pads, and the electric push rod 703 is electrically connected to the controller 2 through a wire;

[0038] In this embodiment, the electric push rod 703 is mainly used to drive the movable plate 702 to move forward and backward, so that the movable plate 702 drives the second clamping plate 707 to move, and the sliding and telescopic between the telescopic cylinder 706 and the fixed sleeve 705 can keep the second clamping plate 707 and the movable plate 702 stable. The supporting compression spring 704 is mainly used to elastically support the second clamping plate 707, so that the second clamping plate 707 can better contact with the fire extinguishing tank 601, thereby achieving the effect of fixing fire extinguishing tanks 601 of different sizes and meeting the needs of users.

[0039] The working process of the utility model is as follows: when using an automatic fire extinguishing device for commercial kitchens, the box body 1 is first moved to a suitable position and fixed, and then the fire extinguishing tank 601 is placed in the installation bin 6 and positioned and clamped. When ensuring that the fire extinguishing tank 601 is in contact with the outer surface of the first clamping plate 701, the electric push rod 703 is started by the controller 2, and the telescopic end of the electric push rod 703 begins to extend and drives the moving plate 702 to move, and the moving plate 702 drives the second clamping plate 707 to get close to the fire extinguishing tank 601 through the fixed sleeve 705 and the telescopic cylinder 706. When the second clamping plate 707 is in contact with the fire extinguishing tank 601, the telescopic cylinder 706 gradually slides toward the inside of the fixed sleeve 705, and the supporting compression spring 704 gradually contracts and generates an elastic force, which makes the second clamping plate 70 7. The fire extinguishing tank 601 and the No. 1 clamping plate 701 are kept in close contact, thereby achieving the fixation of fire extinguishing tanks 601 of different sizes and improving the stability of the fire extinguishing tank 601. Under the action of the temperature detector 301 and the smoke detector 302, once a fire occurs in the kitchen, the controller 2 immediately opens the solenoid valve 603 and starts the electric rotating seat 4. As the solenoid valve 603 is opened, the fire extinguishing material inside the fire extinguishing tank 601 reaches the nozzle 402 along with the hose and the nozzle 5. At the same time, the electric rotating seat 4 drives the nozzle 402 and the thermal imaging camera 403 to rotate. The thermal imaging camera 403 can identify the fire source and transmit the information to the controller 2 through the wire, thereby making the fire extinguishing material sprayed from the nozzle 402 contact with the fire source, thereby improving the fire extinguishing efficiency of the device.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
