Description

Technical Field

[0001] This invention relates to the technical field of non-pressurized fire extinguishing cylinder production equipment, specifically to a fire extinguishing agent filling device. Background Technology

[0002] Non-pressurized fire extinguishing cylinders utilize a gas-generating agent to instantly produce a large amount of gas during operation, which in turn drives a piston to move towards the chamber containing the extinguishing agent in the cylinder, thereby squeezing out the extinguishing agent to extinguish the fire.

[0003] Publication number CN217567235U discloses a piston-type non-pressurized fire extinguishing cylinder and a piston-type non-pressurized fire extinguisher. It can sense external temperature changes through a heat-sensitive wire, and then ignite the gas-generating agent through the heat-sensitive wire when there is a fire risk or when a fire occurs. The gas-generating agent reacts to produce a large amount of gas, which increases the pressure in the first chamber, thereby pushing the piston towards the second chamber and forcing the extinguishing agent out of the second chamber, thus extinguishing the fire through the expelled extinguishing agent.

[0004] However, in the current production of non-pressurized fire extinguishing cylinders, the extinguishing agent is usually delivered manually into the extinguishing agent chamber. However, the manual delivery process can easily lead to uneven distribution of the extinguishing agent in the extinguishing agent chamber, which reduces production quality and efficiency. Summary of the Invention

[0011] In some embodiments, a plurality of plug-in guide posts are provided, the plurality of plug-in guide posts having different sizes and being selectively mounted on the tray, wherein each plug-in guide post is detachably connected to the tray.

[0012] In some embodiments, the mounting portion includes a base, a clamping drive portion, and two clamping portions. The two clamping portions are located on the same side of the base and form the limiting channel. They can move closer to each other and further away from each other in the horizontal direction.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] To address the technical problem that in the production of non-pressurized fire extinguishing cylinders, the extinguishing agent raw materials are usually manually delivered into the extinguishing agent chamber, which can easily lead to uneven distribution of the extinguishing agent raw materials in the extinguishing agent chamber, reducing production quality and efficiency, this invention provides an extinguishing agent filling device that improves the uniformity of extinguishing agent distribution in the cylinder, increases the injection efficiency of the extinguishing agent, and saves manpower.

[0021] Please see Figures 1 to 4 , Figures 1 to 3 This is a schematic diagram of the structure of a fire extinguishing agent filling device according to an embodiment of the present invention. Figure 4 This is a schematic diagram of the cylinder 7 and piston 8 in one embodiment. The fire extinguishing agent filling device is configured to inject fire extinguishing agent into the injection port 7a of the component to be filled. It includes an installation part 1, a rotating part 2, a rotating drive part, and an injection part 3. The rotating part 2 is rotatably installed on the installation part 1 and is used to detachably connect to the component to be filled. When connected to the component to be filled, it can drive the component to be filled to rotate around the axis of the injection port 7a. The rotating drive part is installed on the installation part 1 and connected to the rotating part 2, and is used to drive the rotating part 2 to rotate. The injection part 3 is provided on the installation part 1 and has an injection head 31. The injection head 31 is used to insert into the injection port 7a of the component to be filled and inject fire extinguishing agent into the component to be filled.

[0022] In the fire extinguishing agent filling device provided by the present invention, the cylinder 7 to be filled is assembled on the rotating part 2, and the injection head 31 of the injection part 3 is inserted into the injection port 7a of the cylinder 7. While the fire extinguishing agent is being delivered into the cylinder 7 through the injection head 31, the rotating part 2 is driven to rotate by the rotating drive part, thereby driving the cylinder 7 to rotate synchronously, so as to disturb the fire extinguishing agent raw material in the cylinder 7. This causes the fire extinguishing agent raw material to be driven by inertial force and centrifugal force, forming an internal circulation with a certain intensity, promoting the mutual penetration of different components, improving the uniformity of the distribution of the fire extinguishing agent in the cylinder 7, improving the injection efficiency of the fire extinguishing agent, saving manpower, and thus improving product quality and production efficiency.

[0023] It should be noted that in this design, the component to be filled is the cylinder 7. The detachable assembly of the rotating part 2 and the cylinder 7 can be achieved through magnetic attraction, bolts, or other means. Correspondingly, the rotating part 2 can be configured as an electromagnet base, a rotating base with screw holes, or other forms. Furthermore, the rotating part 2 can be configured as a drive motor, directly driving the rotating part 2 to rotate, or it can be configured as a drive motor connected to gears or belts to drive the rotating part 2.

[0024] In one embodiment, the mounting part 1 extends vertically along a limiting channel 1a for the filling component to pass through; the rotating part 2 includes a tray 21, which is rotatably mounted on the mounting part 1 and located below the limiting channel 1a, with its rotation axis parallel to the extension direction of the limiting channel 1a, and the tray 21 is used to support the filling component; the rotating drive part is connected to the tray 21 and is used to drive the tray 21 to rotate around its own rotation axis.

[0025] In this embodiment, the radial direction of the cylinder 7 is limited by the limiting channel 1a to prevent the cylinder 7 from accidentally deviating in the radial direction. The cylinder 7 is placed on the tray 21 so that the friction between the tray 21 and the cylinder 7 drives the tray 21 to rotate synchronously, thereby realizing the detachable assembly of the rotating part 2 and the cylinder 7. The structure is simple and the operation is simple and convenient.

[0026] It should be noted that in this embodiment, the friction between the tray 21 and the cylinder 7 drives the cylinder 7 to rotate. This not only makes the fluid in the cylinder 7 more uniform, but also allows the cylinder 7 to slide relative to the tray 21 when the tray 21 rotates too fast, thus preventing the cylinder 7 from rotating too fast along with the tray 21 and causing the extinguishing agent to overflow from the injection port 7a.

[0027] In one embodiment, the fire extinguishing agent filling device further includes a plurality of rolling parts 4, which are rotatably mounted on the mounting part 1 and located in the limiting channel 1a, and are arranged sequentially along the circumference of the limiting channel 1a, with the rotation axis of each rolling part 4 parallel to the extension direction of the limiting channel 1a.

[0028] In this embodiment, a rolling part 4 is provided on the inner wall of the limiting channel 1a, so that the cylinder 7 and the rolling part 4 make rolling contact, ensuring that the cylinder 7 can rotate stably with the tray 21. It should be noted that the rolling part 4 can be configured as a roller, a foot roller, or a rotating guide post, etc.

[0029] In one embodiment, the rotating part 2 further includes an anti-slip pad connected to the tray 21 and located on the side of the tray 21 near the limiting channel 1a.

[0030] In this embodiment, an anti-slip pad is provided on the upper side of the tray 21 to increase the friction between the tray 21 and the cylinder 7, thereby increasing the mixing degree of the fluid in the cylinder 7 and improving the uniformity of the extinguishing agent.

[0031] It should be noted that the interior of the cylinder 7 is divided into a gas chamber 7c and an extinguishing agent chamber 7d by the piston 8. The gas chamber 7c is used to place the agent that generates gas, and the extinguishing agent chamber 7d is used to contain the extinguishing agent. The cap corresponding to the gas chamber 7c is provided with an end insertion hole 7b, and the cap corresponding to the extinguishing agent chamber 7d is provided with a filling port 7a.

[0032] In one embodiment, the rotating part 2 further includes a plug guide post 22, which is mounted on the tray 21 and located on the side of the tray 21 near the limiting channel 1a, for insertion into the end insertion hole 7b of the component to be filled.

[0033] In this embodiment, the insertion guide post 22 is inserted into the insertion hole to further guide and center the cylinder 7, thereby improving the ease of assembly.

[0034] In one embodiment, multiple plug-in guide posts 22 are provided, the multiple plug-in guide posts 22 are of different sizes and can be selectively mounted on the tray 21, wherein each plug-in guide post 22 is detachably connected to the tray 21.

The clamping drive part 12 is mounted on the base 11 and connected to the two clamping parts 13, and is used to drive the two clamping parts 13 to move closer to each other and further away in the horizontal direction. The tray 21 is rotatably mounted on the base 11, and the filling part 3 is mounted on the base 11.

[0038] In this embodiment, a limiting channel 1a is formed by two clamping parts 13, and the size of the limiting channel 1a can be flexibly adjusted to suit cylinders 7 of different sizes, improving versatility. It should be noted that in this design, the clamping parts 13 have a certain curvature to prevent the cylinder 7 from accidentally detaching from the limiting channel 1a. Furthermore, the rolling part 4 is located inside the clamping part 13. Additionally, the clamping drive part 12 can be configured as two drive cylinders, hydraulic cylinders, or linear motors to independently drive the two clamping parts 13 to move closer or further apart.

Correspondingly, a display instrument for displaying the value of the weighing scale 5 is provided on the outside of the mounting part 1. It should be noted that the specific structure and principle of the weighing scale 5 are existing technologies and will not be described in detail here.

[0041] In addition, it should be noted that in this solution, the injection unit 3 also includes a laser sensor 6. The laser sensor 6 is installed on the mounting unit 1 and corresponds to the injection port 7a to detect the overflow of the injection port 7a.

Figures 1 to 6 The technical solution of the present invention will be described in detail below: In this scheme, the cylinder 7 is placed on the tray 21 and positioned by the insert guide post 22. Then, the two clamping parts 13 are moved so that the rolling parts 4 on the inner side of the two clamping parts 13 roll and press against the outer wall of the cylinder 7 to prevent the cylinder 7 from accidentally shifting. Then, the injection head 31 is moved to align the injection head 31 with the injection port 7a of the cylinder 7. The weighing scale 5 is then zeroed. Then, the extinguishing agent is injected into the cylinder 7 through the injection head 31, while the tray 21 is rotated until the weighing value of the weighing scale 5 reaches the preset value. At this time, the injection head 31 is controlled to stop injection, and the extinguishing agent filling is completed. The cylinder 7 can then be removed.
