Description

Technical Field

[0001] This utility model relates to the field of explosion-proof technology for oil fume ducts, specifically to a fire-proof and explosion-proof device for ducts. Background Technology

[0002] As a crucial kitchen appliance, the range hood plays a vital role in purifying the kitchen environment. During stove combustion and cooking, it quickly extracts harmful waste and fumes, efficiently venting them outdoors. Simultaneously, the range hood also condenses and collects fumes, effectively reducing indoor pollution and significantly purifying the air, creating a healthier space in the kitchen. Furthermore, the range hood provides safety protection against toxic substances and explosions, adding a strong layer of protection to kitchen safety. However, it is particularly important to note that the exhaust duct of a range hood can easily accumulate a large amount of grease after prolonged use. If exposed to an open flame during use and the temperature reaches a certain level, this grease can ignite rapidly, easily causing a fire and posing a serious threat to kitchen safety.

[0003] A search revealed that patent application CN220287485U discloses a fireproof structure for kitchen exhaust ducts. While this device, when a fire breaks out inside the duct, sends a temperature signal detected by a temperature sensor to a control block, which then activates a buzzer to alert residents to turn off the range hood and prevent flames from entering, and once the fire is extinguished, sends the same signal back to the control block to reopen the duct, this device only monitors the internal conditions and cannot extinguish fires or prevent explosions. Furthermore, since most kitchen exhaust ducts are enclosed, opening them for fire and explosion prevention is inconvenient. Therefore, further improvements are needed. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a pipeline fire prevention and explosion protection device, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A fireproof and explosion-proof device for pipelines includes an oil fume duct body, valves, a frame, and a hydraulic rod, wherein the valves are installed on the oil fume duct body via flanges;

[0007] The top surface of the fume duct body is provided with a through hole, a water tank is placed inside the frame, and mounting blocks are installed at both ends of the water tank. A sealing plate is provided on the output shaft of the hydraulic rod, and an atomizing nozzle is installed on the sealing plate through a water outlet pipe.

[0008] The water tank is equipped with a water pump, and the water pump has a drain pipe.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, both ends of the frame are fitted with limit bolts via threads, and the limit bolts are threaded into the mounting block.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] These threaded locking bolts allow for the fixing and adjustment of the water tank's position within the frame. Furthermore, when maintenance, cleaning, or replacement of the water tank is required, simply unscrewing the locking bolts allows for easy removal of the tank from the frame, simplifying operation and significantly improving the maintainability of the device. For example, after prolonged use, dirt may accumulate inside the water tank; this can be easily cleaned to ensure the cleanliness of the stored water and thus maintain effective firefighting performance.

[0013] Furthermore, a water inlet pipe is embedded and fixed on the top surface of the water tank, the water inlet pipe is connected to the liquid in the water tank, and a sealing cap is installed on the water inlet pipe by thread.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The inlet pipe provides a water replenishment route for the water tank. Before or during use, when the water level in the tank is low, water can be easily added via the inlet pipe. The threaded sealing cap provides a good seal, effectively preventing water leakage and the entry of dust and impurities into the tank during normal use, ensuring water quality and thus the reliability of the fire extinguishing system. For example, in environments with heavy oil fumes, such as kitchens, without a sealing cap, dust can easily enter the water tank, potentially clogging the water pump or atomizing nozzles over time, affecting fire extinguishing effectiveness. The sealing cap design effectively prevents such problems.

[0016] Furthermore, the sealing plate is slidably sleeved inside the through hole, and a sealing ring is fitted onto the outer side of the sealing plate.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The presence of the sealing ring ensures a good seal between the sealing plate and the through hole. Under normal circumstances, it prevents oil fumes and other gases inside the fume duct from leaking out through the through hole, ensuring the airtightness of the duct system and avoiding energy waste and pollution to the surrounding environment. When the hydraulic rod lowers the sealing plate for fire extinguishing, the water mist sprayed from the atomizing nozzle is concentrated inside the duct for fire suppression, and the duct can be closed again after use.

[0019] Furthermore, a U-shaped bracket is installed on the hydraulic rod.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The U-shaped bracket provides additional support for the hydraulic rod. During operation, the hydraulic rod needs to withstand certain pressure and vibration. The U-shaped bracket enhances the stability of the hydraulic rod, preventing it from swaying or shifting during operation, and ensuring that the sealing plate can accurately move up and down within the through-hole, thereby guaranteeing the precision of firefighting operations.

[0022] Furthermore, the U-shaped bracket is fitted with a mounting bolt via threads, and the mounting bolt is threaded into the body of the fume duct.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The threaded mounting bolts ensure a secure and stable connection between the U-shaped bracket and the fume duct body. This connection method also greatly facilitates later maintenance. If repair or replacement of the hydraulic rod or related components is required, the mounting bolts can be easily unscrewed to remove the U-shaped bracket and hydraulic rod, significantly improving maintenance efficiency.

[0025] Furthermore, the end of the drain pipe facing away from the water pump is embedded and fixed inside the outlet pipe, and the outlet pipe is in liquid communication with the water pump through the drain pipe.

[0026] The beneficial effects of adopting the above-mentioned further solutions are:

[0027] During firefighting operations, personnel can turn on the water pump to extract the fire extinguishing liquid stored in the water tank. The fire extinguishing liquid can be a water-based fire extinguishing agent: made with water as the base material and with the addition of various additives. The water is extracted and then supplied to the outlet pipe through the drain pipe to enter the fume duct body for fire extinguishing. During fire extinguishing, the hydraulic rod needs to push the sealing plate to drive the outlet pipe into the fume duct body.

[0028] This utility model provides a fireproof and explosion-proof device for pipelines. It has the following beneficial effects:

[0029] Ease of maintenance: The design of the limit bolts makes the maintenance of the water tank easy. In practical applications, the water tank may accumulate dirt over time, which can be easily removed and cleaned by unscrewing the limit bolts. This simple operation greatly improves the maintainability of the device and ensures the long-term stable operation of the fire extinguishing system.

[0030] Excellent sealing performance: The sealing ring between the sealing plate and the through hole ensures the sealing performance of the piping system. In daily use, it can prevent oil fume leakage, avoid energy waste and environmental pollution; during fire extinguishing, it can ensure that water mist is concentrated in the pipe, improve fire extinguishing efficiency, and can be sealed again after use to maintain the good condition of the pipeline.

[0031] Enhanced stability: The installation of the U-shaped bracket significantly enhances the stability of the hydraulic rod. The hydraulic rod withstands pressure and vibration during operation; the U-shaped bracket effectively prevents it from swaying or shifting, allowing the sealing plate to rise and fall accurately, providing strong support for the precision of firefighting operations.

[0032] Installation and maintenance advantages: The mounting bolt design ensures a secure connection between the U-shaped bracket and the fume duct body, facilitating future maintenance. When repairing or replacing components such as hydraulic rods, simply unscrew the mounting bolts to easily disassemble the relevant parts, improving maintenance efficiency.

[0033] Highly efficient fire extinguishing function: The interconnected design of the drain pipe and water outlet pipe, combined with water-based extinguishing agents, provides an efficient solution for fire extinguishing operations. In the event of a fire, the extinguishing agent in the water tank can be quickly extracted and channeled through the water outlet pipe into the fume extraction duct for fire suppression. Simultaneously, a hydraulic rod pushes a sealing plate to guide the water outlet pipe into the pipeline, ensuring the smooth operation of the fire extinguishing process. Attached Figure Description

[0041] 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.

[0042] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows:

[0043] Example 1

[0044] A fireproof and explosion-proof device for pipelines includes an oil fume duct body 1, a valve 101, a frame 102, and a hydraulic rod 3. The valve 101 is installed on the oil fume duct body 1 via a flange.

[0045] The top surface of the fume duct body 1 has a through hole 104. A water tank 2 is placed inside the frame 102, and mounting blocks 201 are installed at both ends of the water tank 2. A sealing plate 206 is provided on the output shaft of the hydraulic rod 3. An atomizing nozzle 205 is installed on the sealing plate 206 through the water outlet pipe 204.

[0046] A water pump 207 is installed inside the water tank 2, and a drain pipe 203 is provided on the water pump 207;

[0047] Both ends of the frame 102 are fitted with limit bolts 103 via threads, and the limit bolts 103 are threaded into the mounting block 201. These threaded limit bolts 103 allow for fixing and adjusting the position of the water tank 2 within the frame 102. Furthermore, when maintenance, cleaning, or replacement of the water tank 2 is required, simply unscrewing the limit bolts 103 allows for easy removal of the water tank 2 from the frame 102, simplifying the operation and greatly improving the maintainability of the device. For example, after prolonged use, dirt may accumulate inside the water tank 2; this allows for convenient cleaning, ensuring the cleanliness of the stored water and thus guaranteeing that the fire extinguishing effect is not affected.

[0048] A water inlet pipe 202 is embedded and fixed to the top surface of the water tank 2. The water inlet pipe 202 is in liquid communication with the water tank 2, and a sealing cap is installed on the water inlet pipe 202 via threads. The water inlet pipe 202 provides a water replenishment path for the water tank 2. Before or during use, when the water level in the water tank 2 is insufficient, water can be easily added through the water inlet pipe 202. The threaded sealing cap provides a good seal, effectively preventing water leakage and the entry of dust, impurities, etc., into the water tank 2 during normal use, ensuring the quality of the stored water and thus ensuring the reliability of the fire extinguishing system. For example, in environments with a lot of oil fumes, such as kitchens, without a sealing cap, dust can easily enter the water tank 2, which may eventually clog the water pump 207 or the atomizing nozzle 205, affecting the fire extinguishing effect. The sealing cap design effectively avoids such problems.

[0049] The sealing plate 206 is slidably fitted inside the through hole 104, and a sealing ring is fitted to the outer side of the sealing plate 206. The presence of the sealing ring ensures a good seal between the sealing plate 206 and the through hole 104. Under normal circumstances, this prevents oil fumes and other gases inside the fume duct body 1 from leaking through the through hole 104, ensuring the sealing performance of the duct system and avoiding energy waste and pollution to the surrounding environment. When the hydraulic rod 3 lowers the sealing plate 206 to perform a fire extinguishing operation, the water mist sprayed from the atomizing nozzle 205 is concentrated inside the duct for fire extinguishing, and can be closed again after use.

[0050] Example 2

[0051] To avoid inconvenience for personnel handling a fire inside the pipeline, for example, such as Figures 1 to 3 As shown, this utility model also includes: a fume duct body 1, a valve 101, a frame 102 and a hydraulic rod 3. The valve 101 is installed on the fume duct body 1 via a flange.

[0052] The top surface of the fume duct body 1 has a through hole 104. A water tank 2 is placed inside the frame 102, and mounting blocks 201 are installed at both ends of the water tank 2. A sealing plate 206 is provided on the output shaft of the hydraulic rod 3. An atomizing nozzle 205 is installed on the sealing plate 206 through the water outlet pipe 204.

[0053] A water pump 207 is installed inside the water tank 2, and a drain pipe 203 is provided on the water pump 207;

[0054] A U-shaped bracket 301 is installed on the hydraulic rod 3, providing additional support for the hydraulic rod 3. During operation, the hydraulic rod 3 needs to withstand certain pressure and vibration. The U-shaped bracket 301 enhances the stability of the hydraulic rod 3, preventing it from shaking or shifting during operation, and ensuring that the sealing plate 206 can accurately move up and down within the through hole 104, thereby ensuring the accuracy of the fire extinguishing operation.

[0055] The U-shaped bracket 301 is fitted with a threaded mounting bolt 302, which is threaded into the fume duct body 1. This threaded connection ensures a secure and stable connection between the U-shaped bracket 301 and the fume duct body 1. Furthermore, this connection method greatly facilitates later maintenance. If repair or replacement of the hydraulic rod 3 or related components is required, the mounting bolt 302 can be easily unscrewed, allowing the U-shaped bracket 301 and hydraulic rod 3 to be disassembled, significantly improving maintenance efficiency.

[0056] One end of the drain pipe 203, away from the water pump 207, is embedded and fixed in the outlet pipe 204. The outlet pipe 204 is in liquid communication with the water pump 207 through the drain pipe 203. During fire extinguishing operations, personnel can open the water pump 207 to draw the fire extinguishing liquid stored in the water tank 2. The fire extinguishing liquid can be a water-based fire extinguishing agent: made with water as the base material and with the addition of various additives. The water is drawn out and then supplied into the outlet pipe 204 through the drain pipe 203 to enter the oil fume duct body 1 for fire extinguishing.

[0057] Working principle:

[0058] Valve 101 control: Valve 101, which is installed on the fume duct body 1 via a flange, can control the flow of gas in the fume duct. In the event of a fire hazard, it can be closed in time to prevent the fire from spreading through the duct.

[0059] Fire extinguishing water source and control: The water tank 2 is placed inside the frame 102. The two ends of the frame 102 are installed in the mounting blocks 201 at both ends of the water tank 2 by threaded limit bolts 103. This makes the position of the water tank 2 fixed and easy to maintain, clean or replace.

[0060] A fixed water inlet pipe 202 is embedded in the top surface of the water tank 2 to provide a water replenishment path. The threaded sealing cap can prevent water leakage and the entry of dust and impurities, ensuring the quality of the stored water.

[0061] The water pump 207 installed in the water tank 2 can draw fire extinguishing liquid (such as a water-based fire extinguishing agent with various additives) from the water tank 2 and supply the liquid into the outlet pipe 204 through the drain pipe 203.

[0062] Fire extinguishing mechanism: The output shaft of the hydraulic rod 3 is equipped with a sealing plate 206. The sealing plate 206 is slidably sleeved in the through hole 104 opened on the top surface of the oil fume duct body 1, and a sealing ring is installed on the outside. Normally, it prevents oil fume leakage. When extinguishing a fire, it can descend into the duct.

[0063] Atomizing nozzles 205 are installed on the sealing plate 206 through the water outlet pipe 204. When the hydraulic rod 3 pushes the sealing plate 206 down into the oil fume duct body 1, the atomizing nozzles 205 spray the fire extinguishing liquid in the water outlet pipe 204 in the form of water mist to extinguish the fire, thereby preventing fire and explosion of the pipeline.
