Description
Technical Field
[0001] The present application relates to the field of fire extinguishing equipment, and in particular to a fire extinguishing device for small-scale flames. Background Art
[0002] When a textile factory carries out production activities, there are a large number of textile combustible materials in the factory workshop, so it is very easy to catch fire during the production process. Therefore, the factory generally has a large number of fire extinguishers to prevent accidents. At the same time, due to the working environment in the factory, dry powder is generally used for fire extinguishing.
[0003] Existing dry powder fire extinguishers generally contain dry powder and compressed air. When the fire extinguisher is extinguishing a fire, the compressed air inside the fire extinguisher pushes the dry powder to the fire extinguishing port of the fire extinguisher. Then the fire extinguishing port is opened to allow the dry powder to be sprayed out of the fire extinguishing port, thereby extinguishing the fire source.
[0004] Regarding the aforementioned technologies, when a small fire occurs, some workers, due to nervousness or lack of experience, fail to use the fire extinguisher promptly and correctly. This can easily cause dry powder to stick to the gauze, causing it to turn yellow and become difficult to use, thus missing the best opportunity to extinguish the fire. This results in excessive cost losses. Furthermore, dry powder fire extinguishers are relatively expensive, increasing costs for businesses. Summary of the Invention
[0005] In order to facilitate staff to respond to fires in a timely manner and reduce enterprise operating costs, this application provides a fire extinguishing device for small-scale flames.

[0035] The following is combined with Figure 1-7 This application is described in further detail.
[0036] Example 1:
[0037] Example 1 of the present application discloses a fire extinguishing device for small flames. Figure 1 The fire extinguishing device for small-scale flames includes a moving part 1, a fire extinguishing bucket 2 and an opening and closing valve plate 3.
[0038] Reference Figure 1In the present application, the moving part 1 is used to move the fire bucket 2 to the fire location under the action of an external force. The type of the moving part 1 can be a slide bar, a slide rail, a slide groove, a chain, a rack, etc. It is known to those skilled in the art that by installing the fire bucket 2 on the moving part 1, the fire bucket 2 can be moved under the action of an external force. The type of external force is manual power and / or mechanical power. The mechanical power can come from a power element such as a motor, a cylinder, or an oil cylinder. Among them, the reason for manually moving the moving part 1 to move the fire bucket 2 is to facilitate the response to emergencies.
[0039] Specifically, in Example 1 of the present application, there are two moving parts 1, and both moving parts 1 are made of steel pipes, and both moving parts 1 are fixedly installed on the top of the factory workshop. The fire extinguisher 2 is located at the bottom of the moving part 1, and the fire extinguisher 2 is movably matched with the moving part 1 along the length direction of the moving part 1 through the sliding hanging ring 21, so that after a fire occurs, the fire extinguisher 2 can quickly slide to the fire location through the moving part 1. Figure 2 The sliding ring 21 rotates and cooperates with the fire extinguishing barrel 2, so that when the sliding ring 21 slides, the sliding ring 21 can adaptively rotate according to the bending direction of the guide line, thereby reducing the occurrence of the sliding ring 21 getting stuck.
[0040] Reference Figure 2 The fire extinguishing barrel 2 is provided with a powder storage chamber 201 for storing fire extinguishing powder. In the present application, the fire extinguishing powder can be selected from talcum powder, sodium carbonate, sodium bicarbonate or ammonium phosphate, etc., which are materials known to those skilled in the art for extinguishing fires. In Example 1 of the present application, the fire extinguishing powder is preferably talcum powder. Figure 1 , fire bucket 2 is fixedly installed with a pull ring, so that the staff can pull the fire bucket 2 by the pull ring. In addition, the top thread of the fire bucket 2 is equipped with a cover, so that the powder storage chamber 201 is replenished with fire extinguishing powder.
[0041] The opening and closing valve plate 3 opens and closes the powder storage chamber 201 through manual power and / or mechanical power, and the opening and closing valve plate 3 is located at the bottom, side or top of the fire extinguishing bucket 2. In the present application, the fire extinguishing bucket 2 can be used in the following ways: the staff directly operates to dump the fire extinguishing bucket 2 as a whole so that the fire extinguishing powder in the powder storage chamber 201 is poured onto the fire, or the opening and closing valve plate 3 is used to allow the fire extinguishing powder to be poured from the powder storage chamber 201 to the fire under the action of gravity. In addition, in the present application, the mechanical power can come from power elements such as motors, cylinders, and oil cylinders, and the opening and closing valve plate 3 can open and close the powder storage chamber 201 by flipping the opening and closing valve plate 3, pushing and pulling the opening and closing valve plate 3, or hingedly rotating the opening and closing valve plate 3, etc., which are known to those skilled in the art.
[0042] Specifically, in Example 1 of the present application, the opening and closing valve plate 3 is located at the bottom of the fire extinguishing barrel 2, and a valve plate slide groove 202 is provided at the bottom of the fire extinguishing barrel 2. One side of the opening and closing valve plate 3 slides in the horizontal direction to cooperate with the valve plate slide groove 202, so as to facilitate the opening and closing of the bottom of the powder storage chamber 201 by pushing and pulling the opening and closing valve plate 3, and facilitate the staff to pour out the fire extinguishing powder from the powder storage chamber 201, so that the fire extinguishing powder can be easily scattered to the fire location under the action of gravity to eliminate the fire, and reduce the occurrence of large-scale diffusion of the fire extinguishing powder under the action of pressure.
[0043] Reference Figure 3 The opening and closing valve plate 3 is fixedly installed with a valve plate pull ring 31, and the opening and closing valve plate 3 is integrally provided with a closing protrusion 32. The closing protrusion 32 is located on the side of the opening and closing valve plate 3 away from the valve plate slide groove 202, so that the fire extinguishing powder is not easily leaked from the gap between the opening and closing valve plate 3 and the fire extinguishing barrel 2 through the closing protrusion 32.
[0044] The implementation principle of the fire extinguishing device for small-scale flames in Example 1 of the present application is as follows: when a fire occurs in a textile room, the fire extinguishing bucket 2 is moved along the moving part 1 to the fire location, and then the opening and closing valve plate 3 is pulled by the valve plate pull ring 31 to open the powder storage chamber 201, so that the fire extinguishing powder is scattered to the fire location under the action of gravity, and then the coverage during dry powder fire extinguishing is easier to control to reduce cost losses, which makes it easier for staff to respond to the fire in a timely manner and reduces the operating costs of the enterprise.
[0045] Example 2:
[0046] Example 2 of the present application discloses a fire extinguishing device for small flames. In addition to all the technical features of Example 1, it also includes the following technical features:
[0047] Reference Figure 4 and Figure 5 A guide cone barrel 4 is provided in the powder storage chamber 201. The diameter of the top of the guide cone barrel 4 is smaller than the diameter of the bottom of the guide cone barrel 4. The guide cone barrel 4 is fixed to the inner wall of the powder storage chamber 201 through a connecting plate 41. Figure 6 The connecting plate 41 is provided with a plurality of partition grooves 411, which are evenly distributed along the circumference of the connecting plate 41. A cone chamber 401 is provided inside the guide cone 4. The cone chamber 401 is vertically penetrated to facilitate the dispersion of fire extinguishing powder from the powder storage chamber 201 through the cone chamber 401 to the fire location.
[0048] Reference Figure 5 and Figure 7A cone barrel orifice plate 42 is installed on the top of the guide cone barrel 4, and the cone barrel orifice plate 42 is buckled on the top of the guide cone barrel 4 through the annular protrusion 421 at the bottom, so that the fire extinguishing powder can evenly enter the cone barrel chamber 401 through several through holes opened in the cone barrel orifice plate 42.
[0049] The implementation principle of the fire extinguishing device for small-scale fires in Example 2 of the present application is as follows: Based on the implementation principle of Example 1, a cone barrel chamber 401 is further provided, so that the fire extinguishing powder is first scattered from the bottom of the powder storage chamber 201 and the bottom of the cone barrel chamber 401 simultaneously, thereby extinguishing the fire in the area with more serious fire. After the fire extinguishing powder has been scattered for a period of time, the fire extinguishing powder no longer scatters from the bottom of the cone barrel chamber 401, and the fire extinguishing powder is then evenly scattered around the surrounding area of the cone barrel 4, thereby extinguishing the fire in a larger area with less serious fire.
[0050] Example 3:
[0051] Example 3 of the present application discloses a fire extinguishing device for small-scale flames. In addition to all the technical features of Example 1 or Example 2, it also includes the following technical features:
[0052] The sliding hanging ring 21 is equipped with a power pulley (not shown in the figure), which is driven by a motor (not shown in the figure), and the power pulley rolls and slides with the moving part 1, so that after a fire occurs, the power pulley drives the sliding hanging ring 21 to automatically move to the fire location.
[0053] Example 4:
[0054] Example 4 of the present application discloses a fire extinguishing device for small-scale flames, which differs from Example 1 mainly in that the opening and closing valve plate 3 opens and closes the bottom of the powder storage chamber 201 in a different manner.
[0055] The opening and closing valve plate 3 rotates and cooperates with the inner wall of the powder storage chamber 201, and the opening and closing valve plate 3 is driven to rotate by a motor (not shown in the figure) so that the opening angle of the opening and closing valve plate 3 can be adjusted by the motor, thereby adjusting the scattering amount of fire extinguishing powder according to the fire situation.
[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
