Description

Technical Field

[0001] The present invention relates to the technical field of fire extinguishers, and in particular to a manufacturing method of a carbon fiber fire extinguisher gas cylinder and a carbon fiber fire extinguisher structure. Background Art

[0002] A fire extinguisher is a portable fire extinguishing tool. Chemicals are placed inside the fire extinguisher to extinguish fires. Fire extinguishers are one of the common fire fighting equipment and are stored in public places or places where fires may occur. Different types of fire extinguishers are filled with different components and are designed for different causes of fires. The commonly used fire extinguishers in fires are of five types: foam, dry powder, acid-base, CO2, and 1211. The body of the fire extinguisher is usually red and printed with the name, model, fire extinguishing type and capacity, fire extinguishing agent, and the types and quantities of driving gases of the fire extinguisher, and the usage method of the fire extinguisher is illustrated in words and images. A fire extinguisher consists of components such as a cylinder body, a nozzle, etc. With the help of the driving pressure, the filled fire extinguishing agent can be ejected to achieve the purpose of extinguishing the fire.

[0003] The existing fire extinguisher shells are usually made of steel, and the steel shells have the following disadvantages: the weight of the fire extinguisher is too heavy and not easy to carry, and the steel is also prone to rust, especially in harsh environments, the service life will be greatly reduced.

[0004] In summary, there is a need for a manufacturing method of a carbon fiber fire extinguisher gas cylinder and a carbon fiber fire extinguisher structure that can improve the service life at present. Summary of the Invention

[0005] The present invention is to overcome the deficiency that the fire extinguisher shell made of steel in the prior art is prone to rust and the service life will be greatly reduced in harsh environments, and provides a manufacturing method and a carbon fiber fire extinguisher structure that can improve the service life.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A manufacturing method of a carbon fiber fire extinguisher gas cylinder includes the following steps: Step 1, process a mold of a carbon fiber shell according to the size of the bottle body of the fire extinguisher; Step 2, cut the carbon fiber cloth into corresponding sheets and strips according to the size of the mold; Step 3, place the cut carbon fiber material in the mold; Step 4, after the placement is completed, evenly brush or pour the resin glue on the carbon fiber cloth; Step 5, put the mold filled with materials and impregnated with resin into a hot pressing forming device to make a carbon fiber shell; Step 6, put the bottle body into the carbon fiber shell and fix the two into a whole through a clamp; Step 7: Align the connector at the bottom of the valve body with the bottle mouth at the top of the bottle body and screw it in, and then use auxiliary tools to tighten the valve body at the bottle mouth.

[0007] The present invention uses carbon fiber material to make the shell of the fire extinguisher. Since the carbon fiber material is light, the overall weight of the fire extinguisher body is reduced, which is convenient for carrying and moving. Moreover, the carbon fiber material is more suitable for various harsh environments and will not rust, greatly improving the service life.

[0008] Preferably, in Step 4, the resin glue solution is polyurethane containing quaternary ammonium salt groups. It continuously eliminates static electricity through the ion conduction mechanism, well avoiding the risk of the reaction or explosion of the agent in the fire extinguisher caused by static electricity accumulation, and also avoiding the harm to the user caused by the static electricity on the shell of the fire extinguisher.

[0009] The present invention also provides a carbon fiber fire extinguisher structure, including a bottle body and a valve body. The top of the bottle body is provided with a bottle mouth, and the bottom of the valve body is provided with a connector matching the bottle mouth. The inner side of the connector is provided with a feed channel. The inner side wall of the bottle mouth is provided with a first internal thread area, and the outer side wall of the connector is provided with a first external thread area. The connector is threadedly connected with the bottle mouth through the cooperation of the first external thread area and the first internal thread area. The inside of the bottle body is connected to the inside of the valve body through the feed channels on the bottle mouth and the connector in sequence. The outer edge of the port of the connector is provided with an annular inclined guide surface, and the annular inclined guide surface inclines towards the inner side of the connector from the bottom of the connector to the port of the connector. A sealing extrusion ring is also fixed on the annular inclined guide surface. The feed channel is located inside the sealing extrusion ring. An annular flanging I matching the port of the connector is also fixed on the inner side wall of the bottle mouth. An annular inclined pressing surface matching the annular inclined guide surface is fixed on the surface of the annular flanging I facing the connector. The annular inclined guide surface and the annular inclined pressing surface are parallel, and the sealing extrusion ring is placed between the annular inclined guide surface and the annular inclined pressing surface. The connector of the valve body is threadedly connected with the bottle mouth of the bottle body through the cooperation of the first external thread area and the first internal thread area. The connection method is simple and easy to operate, convenient for installation and disassembly, reducing the difficulty of later maintenance and repair, and having good sealing performance and strong stability. Through the design of the annular inclined guide surface, the smoothness of the connector entering the bottle mouth is improved, making the operation simple, convenient, time-saving and labor-saving. The annular inclined guide surface and the annular inclined pressing surface are sealed through the sealing extrusion ring, improving the sealing effect between the connector and the bottle mouth, avoiding leakage, and improving the service life of the fire extinguisher. When the connector is tightened in the bottle mouth, the sealing extrusion ring just presses tightly between the annular inclined guide surface and the annular inclined pressing surface, further strengthening the sealing effect.

[0010] Preferably, a valve cavity is provided inside the valve body. The feed channel is located below the valve cavity. The valve cavity and the feed channel are connected through a material guiding hole. A valve rod is installed on the valve body. The bottom end of the valve rod passes through the material guiding hole and is placed inside the feed channel. The diameter of the valve rod is smaller than the diameter of the material guiding hole. A valve rod through-hole is provided on the top surface of the valve cavity. The top end of the valve rod passes through the valve rod through-hole and is placed outside the valve body. A sealed sliding connection is provided between the valve rod and the valve rod through-hole. A valve core matching the material guiding hole is fixed to the bottom end of the valve rod. The width of the valve core is smaller than the width of the feed channel. A pressing handle is installed on the top of the valve body. A lifting handle is fixed to the side wall of the valve body. One end of the pressing handle is hinged to the valve body. The other end of the pressing handle is located above the lifting handle. The top end of the valve rod is located below the pressing handle and contacts the pressing handle. A safety pin is installed between the pressing handle and the lifting handle. An annular flange two and a spring one are fixed to the inner side wall of the feed channel. The spring one is placed between the valve core and the annular flange two. The top end of the spring one is connected to the valve core. The bottom end of the spring one is placed on the annular flange two. The settings of the pressing handle, the lifting handle, and the safety pin are all well-known prior arts to those skilled in the art and will not be elaborated further. In the unused state, the pressing handle is in the locked state. At this time, the valve core is pressed against the material guiding hole under the elastic force of the spring one to block it, making the inside of the bottle body in a sealed state. When in use, first remove the safety pin to unlock the pressing handle, and then press the pressing handle downwards to drive the valve rod and the valve core to move downwards, so that the valve core disengages from the material guiding hole to open the material guiding hole. At this time, the fire extinguishing medium inside the bottle body will automatically spray out along with the high-pressure air flow through the material guiding hole. The structure is simple and the operation is convenient.

[0011] Preferably, the top of the valve core is adapted to the material guiding hole, and the bottom of the valve core is in a tapered shape. The top end of the spring one is sleeved on the bottom of the valve core. The top of the valve core is designed in a tapered shape, which can play a role in guiding the high-pressure air flow and the fire extinguishing medium ejected, reducing wind noise, increasing the flow rate, and improving the fire extinguishing efficiency.

[0012] Preferably, an annular guiding slope one is provided on the surface of the annular flange one facing the inside of the bottle body. The annular guiding slope one inclines upwards towards the inner side of the annular flange one. An annular guiding slope two is provided on the surface of the annular flange two facing the inside of the bottle body. The annular guiding slope two inclines upwards towards the inner side of the annular flange one. The surfaces of the annular flange one and the annular flange two facing the inside of the bottle body are both designed in an inclined plane type, which can play a further role in guiding the high-pressure air flow and the fire extinguishing medium ejected, reducing wind noise, increasing the flow rate, and improving the fire extinguishing efficiency.

[0013] Preferably, a discharge nozzle is provided on the side wall of the valve chamber. A baffle matching the discharge nozzle is also provided on the side wall of the valve chamber. The baffle is placed at the discharge nozzle and is slidably connected to the valve chamber. The valve rod and the baffle are connected through a transmission structure. In the unused state, the baffle blocks the discharge nozzle, which can effectively prevent moisture, mosquitoes, etc. from entering the valve body through the discharge nozzle, avoiding interference and corrosion of the internal parts of the valve body, playing a role in protecting the valve body, and thus improving the service life of the fire extinguisher.

[0014] Preferably, a baffle chute is provided on the top surface of the valve chamber. One end of the baffle is placed in the baffle chute and is slidably connected thereto. The bottom surface of the baffle chute and the baffle are connected by a second spring. The other end of the baffle matches the discharge nozzle. In the unused state, the other end of the baffle blocks the discharge nozzle. The transmission structure includes a card. The card is placed on the top surface of the valve chamber and is slidably connected thereto. A card chute is provided on the side wall of the valve chamber. The card chute and the discharge nozzle are located on opposite side walls of the valve chamber respectively. One end of the card is placed in the card chute and is slidably connected thereto. The bottom surface of the card chute and the card are connected by a third spring. A pressure groove matching the other end of the card is provided on the baffle. In the unused state, the other end of the card is placed in the pressure groove and the second spring is in a stretched state. The valve rod is placed on the side of the card. A block is fixed on the side wall of the valve rod. A notch matching the block is provided on the side wall of the card. In the unused state, the block is placed in the notch and the third spring is in a stretched state. When the valve rod and the valve core move downward, the fire extinguishing medium in the bottle body will be automatically ejected through the material guiding hole along with the high-pressure air flow. At the same time, the block on the valve rod automatically disengages from the notch on the card. The card automatically retracts into the card chute under the elastic force of the third spring and releases the locking effect on the baffle, so that the baffle also automatically retracts into the baffle chute under the elastic force of the second spring, thereby opening the discharge nozzle to ensure the smooth ejection of the fire extinguishing medium. The structure is simple and the control is convenient.

[0015] Preferably, a first pressing inclined surface is provided on the block. The first pressing inclined surface is located on the side surface of the block facing the baffle. The first pressing inclined surface inclines downward towards the direction close to the baffle. A second pressing inclined surface matching the first pressing inclined surface is provided on the side wall of the notch. The second pressing inclined surface is parallel to the first pressing inclined surface and the two are in contact. In the unused state, the block on the valve rod applies an extrusion force to the card through the cooperation of the first pressing inclined surface and the second pressing inclined surface, so that the card presses the baffle against the side wall of the valve chamber, greatly improving the blocking effect of the baffle on the discharge nozzle.

[0016] Preferably, a fire extinguishing medium is stored in the bottle body. A rotating column bracket is fixed inside the bottle body. A rotating column is installed on the rotating column bracket and is rotatably connected thereto. A plurality of driving blades are fixed to the top end of the rotating column. The driving blades are annularly fixed to the outer side wall of the rotating column. The driving blades are disposed at the bottle mouth and are located below the bottle mouth. When the high-pressure air flow and the fire extinguishing medium in the bottle body are ejected, a rotating force is applied to the driving blades and the rotating column is driven to rotate. A column groove is provided on the bottom surface of the rotating column. A guiding column is installed in the column groove. An internal thread area two is provided on the inner side wall of the column groove. An external thread area two that matches the internal thread area two is provided on the outer side wall of the top of the guiding column. The top of the guiding column is installed in the column groove and is threadedly connected thereto through the cooperation of the external thread area two and the internal thread area two. A limiting rod is fixed to the inner bottom surface of the bottle body. A limiting sliding groove that matches the limiting rod is provided on the bottom surface of the guiding column. The limiting rod is placed in the limiting rod sliding groove and is slidably connected thereto up and down. An activity push plate that matches the inner wall of the bottle body is fixed to the bottom of the guiding column. The activity push plate is hermetically and slidably connected to the bottle body. The fire extinguishing medium is disposed above the activity push plate. When the high-pressure air flow and the fire extinguishing medium in the bottle body are ejected, a rotating force is applied to the driving blades and the rotating column is driven to rotate. At this time, under the guiding action between the external thread area two and the internal thread area two and the limiting action between the limiting rod and the limiting sliding groove, the guiding column and the activity push plate thereon are driven to automatically move towards the direction close to the bottle mouth. On the one hand, the movement of the activity push plate can push the fire extinguishing medium towards the bottle mouth, making the subsequent fire extinguishing medium closer to the bottle mouth and improving the ejection efficiency. On the other hand, the movement of the activity push plate can reduce the space where the fire extinguishing medium is located to ensure that the fire extinguishing medium can be continuously ejected under high pressure, further improving the ejection efficiency.

[0017] The beneficial effects of the present invention are as follows: the overall weight is reduced, which is convenient for carrying and moving; the service life is improved; the connection method is simple and easy to operate, which is convenient for installation and disassembly, and reduces the difficulty of later maintenance and repair; the connection has good sealing performance and strong stability; the structure is simple, and the operation and control are convenient; the wind noise is reduced, the flow rate is increased, and the fire extinguishing efficiency is improved; it has the function of protecting the valve body; the ejection efficiency is improved.

[0030] As Figure 1 , Figure 2 and Figure 3As shown in the figure, a fire extinguishing medium 28 is stored in the bottle body 1. A rotating column support 29 is fixed inside the bottle body 1. A rotating column 30 is installed on the rotating column support 29 and is rotatably connected thereto. A plurality of driving vanes 31 are fixed on the top end of the rotating column 30.

At this time, the fire extinguishing medium 28 in the bottle body 1 will automatically be ejected through the material guiding hole 9 along with the high-pressure air flow. At the same time, the clamping block 26 on the valve rod 10 automatically disengages from the notch 27 on the card 22. The card 22 automatically retracts into the card sliding groove 23 under the elastic force of the spring III 24 and releases the locking effect on the baffle 19, so that the baffle 19 also automatically retracts into the baffle sliding groove 20 under the elastic force of the spring II 21, thereby opening the material outlet nozzle 18 to ensure the smooth ejection of the fire extinguishing medium 28.

[0032] When the high-pressure air flow and the fire extinguishing medium 28 in the bottle body 1 are ejected, a rotating force is applied to the driving vanes 31 and the rotating column 30 is driven to rotate. At this time, under the guiding action between the external thread area II and the internal thread area II and the limiting action between the limiting rod 34 and the limiting sliding groove 35, the guiding column 33 and the active push plate 36 thereon are driven to automatically move towards the direction close to the bottle mouth 3. On the one hand, the movement of the active push plate 36 can push the fire extinguishing medium 28 towards the bottle mouth 3, so that the subsequent fire extinguishing medium 28 is closer to the bottle mouth 3. On the other hand, the movement of the active push plate 36 can reduce the space where the fire extinguishing medium 28 is located to ensure that the fire extinguishing medium 28 can be continuously ejected under high pressure.
