A thermal wire triggering mechanism for a suspended dry powder fire extinguishing device

Abstract

This utility model relates to the technical field of dry powder fire extinguishing devices, specifically a heat-sensitive wire triggering mechanism for a suspended dry powder fire extinguishing device. It includes a tank, a spray port mounted on the top surface of the tank, a filling pipe mounted on the right side of the spray port, a temperature control pipe mounted on the top surface of the spray port, and an installation frame mounted on the top surface of the tank. It also includes an abutment block mounted on the front and rear surfaces of a stabilizing ring, a top frame mounted on the lower surface of a connecting steel wire rope, and a lifting block mounted on the lower end of the top frame, with the lifting block mounted on the lower surface of the abutment block. This utility model uses the connecting steel wire rope to raise the top frame and lifting block. When the lifting block rises, it abuts against the lower surface of the abutment block. The design of two sets of lifting blocks raises the abutment block, thereby raising the stabilizing ring and the temperature control pipe. This causes the temperature control pipe to tear and break, allowing the dry powder extinguishing agent inside the tank to be sprayed out from the spray port.

Description

Technical Field

[0001] This utility model relates to the technical field of dry powder fire extinguishing devices, specifically a thermal wire triggering mechanism for a suspended dry powder fire extinguishing device. Background Technology

[0002] Dry powder fire extinguishers contain dry powder extinguishing agents such as ammonium phosphate. These dry powder extinguishing agents are free-flowing and dry, and are composed of inorganic salts and pulverized and dried additives. They can effectively extinguish initial fires.

[0003] In response, Chinese patent application publication number CN213964938U discloses a suspended pressurized dry powder fire extinguishing device, including a tank and a spray port. The spray port is threaded to the center of the top of the tank. A push rod is installed through the left side of the spray port, and a thermoelectric trigger is embedded in the left side of the push rod. A temperature sensing wire is fixedly connected to the left side of the thermoelectric trigger. A baffle is fixedly connected to the top of the spray port, and a filling port is embedded in the right side of the spray port. A detector is embedded in one end of the spray port, and a temperature control tube is embedded in the bottom end of the baffle. This suspended pressurized dry powder fire extinguishing device, through the coordinated use of the temperature sensing wire, push rod, and thermoelectric trigger, allows the temperature sensing wire to naturally trigger the thermoelectric trigger under high temperature conditions. The thermal expansion of the thermoelectric trigger then triggers the push rod to push out the temperature control tube. At this time, the spray port sprays out the built-in dry powder without resistance, or the control terminal can activate the thermoelectric trigger via the power line, thus providing dual protection to ensure fire extinguishing efficiency.

[0004] However, in actual use, when activating a dry powder fire extinguisher, if the push rod cannot contact and damage the temperature control tube, the dry powder cannot be sprayed out to extinguish the fire. This triggering effect is poor and cannot reliably contact and break the temperature control tube. Therefore, improving and perfecting the above-mentioned problems has become an urgent issue to be addressed. Utility Model Content

[0005] The purpose of this utility model is to provide a thermal triggering mechanism for a suspended dry powder fire extinguishing device, so as to solve the problem mentioned in the background art that when the dry powder fire extinguisher is activated, if the top rod cannot contact and damage the temperature control tube, the dry powder cannot be sprayed out to extinguish the fire. This triggering effect is poor and cannot reliably contact and break the temperature control tube.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat-sensitive wire triggering mechanism for a suspended dry powder fire extinguishing device, comprising a tank, a spray port installed on the top surface of the tank, a filling pipe installed on the right side of the spray port, a temperature control pipe installed on the top surface of the spray port, an installation frame installed on the top surface of the tank, a connecting steel wire rope inserted and installed inside the installation frame, and a stabilizing ring installed on the outer surface of the temperature control pipe; An abutment block is installed on the front and rear surfaces of the stabilizing ring. A top frame is installed on the lower surface of the connecting wire rope. A lifting block is installed at the lower end of the top frame. The lifting block is installed on the lower surface of the abutment block. A side block is fixedly connected to the left side surface of the mounting frame.

[0007] Preferably, a limiting plate is installed on the top surface of the side block, and a limiting roller is installed inside the limiting plate.

[0008] Preferably, a counterweight cylinder is installed inside the side block through the lower end of the connecting wire rope, and a support block is provided at the lower end of the counterweight cylinder.

[0009] Preferably, a connecting rope and a connecting post are installed sequentially from front to back at the lower end of the side block, and an electric heating ring is installed at the lower end of the connecting post.

[0010] Preferably, the electric heating ring is mounted on the outer surface of the connecting rope, and the end of the connecting rope away from the side block is mounted on the upper surface of the support block.

[0011] Preferably, the front surface of the tank is provided with a mounting bracket, the top surface of the inner wall of the mounting bracket is provided with a fixing groove, the lower surface of the mounting bracket is provided with a fixing bracket, and the top surface of the fixing bracket is fixedly connected with a fixing column, and the fixing column and the fixing groove are mutually adapted.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The heat-sensitive wire triggering mechanism of this suspended dry powder fire extinguishing device, through a set of components including a temperature control tube, mounting frame, connecting steel wire rope, stabilizing ring, contact block, top frame, lifting block, side block, limiting plate, limiting roller, counterweight cylinder, and support block, first fills the required dry powder fire extinguishing agent through the filling tube. If a fire occurs in the external environment and the temperature control tube does not automatically break, the temperature sensor on the outer surface of the mounting frame senses the temperature. When the temperature exceeds the standard temperature, the electric heating ring is activated, which heats the connecting rope, causing it to disconnect. The support block then follows the disconnected rope. As the counterweight cylinder falls downwards, it pulls the connecting steel wire rope downwards. The connecting steel wire rope is limited by the limiting roller. At this time, the connecting steel wire rope inside the mounting frame rises, which in turn drives the top frame and lifting block to rise. When the lifting block rises, it abuts against the lower surface of the contact block. The design of two sets of lifting blocks lifts the contact block, thereby lifting the stabilizing ring and the temperature control tube. This causes the temperature control tube to be pulled and broken, and then the dry powder extinguishing agent inside the tank is sprayed out from the inside of the spray port. The overall spraying effect is good, demonstrating the practicality of the design.

[0013] The heat-sensitive wire triggering mechanism of this suspended dry powder fire extinguishing device, through the setting of connecting ropes, mounting brackets, fixing brackets, and fixing columns, can stably support the position of the support block through the connecting ropes during use, and then support the counterweight cylinder through the support block, ensuring the stability of the counterweight cylinder when not in use. When installing the tank, the mounting bracket is installed on the top surface of the fixing bracket, and then the fixing column is snapped into the fixing groove, which can install the tank in the designated position, demonstrating the functionality of the design.

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 One embodiment provided by this utility model: A thermal triggering mechanism for a suspended dry powder fire extinguishing device is disclosed. The spray port 2, temperature control tube 4, electric heating ring 18, and temperature sensor used in this application are all commercially available products. Their principles and connection methods are well-known prior art and will not be elaborated upon here. The device includes a tank 1, with a spray port 2 mounted on its top surface. A filling tube 3 is mounted on the right side of the spray port 2. A temperature control tube 4 is mounted on the top surface of the spray port 2. A mounting frame 5 is mounted on the top surface of the tank 1. A temperature sensor is installed on the outer surface of the mounting frame 5. A connecting steel wire rope 6 is inserted inside the mounting frame 5. A stabilizing ring 7 is mounted on the outer surface of the temperature control tube 4. A counterweight is installed inside the side block 11 through the lower end of the connecting steel wire rope 6. The counterweight cylinder 14 has a support block 15 at its lower end. The front surface of the tank body 1 has a mounting frame 19 with a fixing groove on the top surface of the inner wall of the mounting frame 19. The lower surface of the mounting frame 19 has a fixing frame 20, and the top surface of the fixing frame 20 is fixedly connected to a fixing column 21. The fixing column 21 and the fixing groove are mutually compatible. The position of the support block 15 can be stably supported by the connecting rope 16. The counterweight cylinder 14 can also be supported by the support block 15 to ensure the stability of the counterweight cylinder 14 when it is not in use. When installing the tank body 1, the mounting frame 19 is installed on the top surface of the fixing frame 20, and then the fixing column 21 is snapped into the fixing groove to install the tank body 1 in the designated position. A contact block 8 is installed on the front and rear surfaces of the stabilizing ring 7. A top frame 9 is installed on the lower surface of the connecting wire rope 6. A lifting block 10 is installed at the lower end of the top frame 9 and is installed on the lower surface of the contact block 8. A side block 11 is fixedly connected to the left side surface of the mounting frame 5. A limit plate 12 is installed on the top surface of the side block 11. A limit roller 13 is installed inside the limit plate 12. A connecting rope 16 and a connecting column 17 are installed sequentially from front to back at the lower end of the side block 11. An electric heating ring 18 is installed at the lower end of the connecting column 17 and is installed on the outer surface of the connecting rope 16. The end of the connecting rope 16 away from the side block 11 is installed on the upper surface of the support block 15. The counterweight cylinder 14, the connecting wire rope 6, and the top frame 9 form a lever design. When the counterweight cylinder 14 descends, the top frame 9 rises. The required dry powder extinguishing agent is filled through the filling pipe 3. If a fire occurs in the external environment and the temperature control pipe 4 does not automatically break, then... The temperature sensor on the outer surface of the mounting frame 5 senses the temperature. When the temperature is higher than the standard temperature, the electric heating ring 18 is activated. The electric heating ring 18 heats the connecting rope 16, causing it to disconnect. The support block 15 then falls downwards along with the connecting rope 16, and the counterweight cylinder 14 also falls downwards. As the counterweight cylinder 14 falls, it drives the connecting steel wire rope 6 downwards. The connecting steel wire rope 6 is limited by the limiting roller 13. At this time, the connecting steel wire rope 6 inside the mounting frame 5 rises, which in turn drives the top frame 9 and the lifting block 10 to rise. When the lifting block 10 rises, it abuts against the lower surface of the contact block 8. The design of the two sets of lifting blocks 10 lifts the contact block 8, thereby lifting the stabilizing ring 7 and the temperature control tube 4. This causes the temperature control tube 4 to be pulled and broken, and the dry powder extinguishing agent inside the tank 1 is sprayed out from the inside of the spray port 2, resulting in a better overall spraying effect.

[0018] Working principle: When using this device, the operator first connects it to an external power source to provide electrical power. The required dry powder extinguishing agent is then filled through the filling tube 3. If a fire occurs in the external environment and the temperature control tube 4 fails to break automatically, the temperature sensor on the outer surface of the mounting frame 5 detects the temperature. When the temperature exceeds the standard temperature, the electric heating ring 18 is activated. The electric heating ring 18 heats the connecting rope 16, causing it to disconnect. The support block 15 then falls downwards along with the connecting rope 16, and simultaneously, the counterweight cylinder 1... 4 will also fall downwards. When the counterweight cylinder 14 moves downwards, it will drive the connecting steel wire rope 6 to move downwards. The connecting steel wire rope 6 is limited by the limiting roller 13. At this time, the connecting steel wire rope 6 inside the mounting frame 5 will rise. Then the connecting steel wire rope 6 will drive the top frame 9 and the lifting block 10 to rise. When the lifting block 10 rises, it will abut against the lower surface of the abutment block 8. Thus, the abutment block 8 will be lifted by the design of the two sets of lifting blocks 10, which can lift the stabilizing ring 7 and the temperature control tube 4. Therefore, the temperature control tube 4 can be pulled and broken. Then the dry powder extinguishing agent inside the tank 1 will be sprayed out from the inside of the spray port 2. The support block 15 can be stably supported by the connecting rope 16, and the counterweight cylinder 14 can also be supported by the support block 15, ensuring the stability of the counterweight cylinder 14 when it is not in use. When installing the tank body 1, the mounting bracket 19 can be installed on the top surface of the fixing bracket 20, and then the fixing column 21 can be clamped between the fixing groove. The above is the working principle of this utility model.

[0019] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
