Description

Technical Field

[0001] This invention belongs to the field of gas leak detection technology, specifically a gas leak wireless alarm with quick-installation function. Background Technology

[0002] A wireless gas leak alarm is a safety device that ensures gas safety by monitoring the concentration of combustible gas in the air in real time and sending alarm signals wirelessly. When the gas concentration in the air reaches a set critical point, the alarm will automatically issue an alarm signal and remotely push the alarm information to the user terminal or monitoring platform, reminding personnel to take appropriate measures in a timely manner.

[0003] Patent CN221766165U discloses a gas leak alarm, including an alarm body and a buzzer alarm mounted on the alarm body. A microcontroller and an electromagnetic switch are installed on the control panel inside the alarm body. The key feature is that an exhaust pipe is connected to one outer wall of the alarm body, and a retaining ring is installed at the end of the exhaust pipe. An exhaust box is installed inside the alarm body, with an exhaust port on its surface. The exhaust box is connected to the exhaust pipe, and an exhaust fan is installed inside the exhaust box. This patent, by connecting an exhaust pipe to one outer wall of the alarm body, allows the alarm body to communicate with the exhaust pipe, thereby expelling leaked gas, improving indoor air circulation, diluting the gas concentration in the air, and the design of a stretchable corrugated pipe and exhaust duct allows the exhaust pipe to expand and contract with environmental changes, adapting to different installation environments and improving the adaptability and convenience of the alarm.

[0004] However, the above technical solutions still have the following shortcomings in practical applications: Outside gas enters the alarm through the air inlet, flows through the chamber containing the core gas sensor, and then naturally flows out through the exhaust port, thus achieving continuous monitoring. Furthermore, to prevent external contaminants from affecting the sensor's detection accuracy and long-term stability, a dust filter is installed at the air inlet to intercept impurities. However, after prolonged use, the intercepted impurities can clog the filter pores, reducing gas flow efficiency and consequently affecting the accuracy of the monitoring results.

[0005] Furthermore, existing technologies often use rotating brushes to clean the surface of the dust filter to prevent impurities from clogging it. However, during the cleaning process, the brushes only sweep away impurities adhering to the surface of the dust filter, without completely removing them from the vicinity of the air inlet. The impurities that are kicked up are easily carried back to the surface of the dust filter or re-adsorbed around the filter holes by the airflow and their own gravity, resulting in repeated adhesion. This causes the dust filter to become clogged again in a short period of time, resulting in an unsatisfactory cleaning effect. It is difficult to maintain the continuous unobstructed air intake channel, which in turn affects the efficiency of gas entering the sensor chamber and is detrimental to ensuring the accuracy of monitoring results.

Specifically, by using a pin to penetrate the filter holes, impurities embedded in the inner wall of the filter holes can be pushed out, solving the problem that simple surface cleaning is insufficient to remove blockages inside the holes; the hexagonal barrier structure formed by the radial plate and the scraper cloth gathers the pushed-out and attached impurities to the horizontal spiral blades during the shrinking process, ensuring that the impurities are effectively collected rather than scattered to the surrounding area, fundamentally preventing the phenomenon of impurities falling back into the dustproof mesh under the action of airflow.

Through the plug-in cooperation between the plug and the mounting base, combined with the automatic locking of the plug rod under the action of spring two, there is no need for complicated operations such as tightening bolts with tools.

[0027] An inclined tube 16 is fixedly connected to one side of the top of the vertical tube 14. One end of the inclined tube 16 is connected to a dust box 2. The dust box 2 is provided with a cover 7 and is fixedly installed on the main body 1 of the alarm.

[0028] A gear housing 13 is fixedly connected to the top of the vertical tube 14. A vertically arranged rotating shaft 28 is rotatably provided on one side of the gear housing 13. The bottom of the rotating shaft 28 is rotatably inserted into the horizontal tube 24. A bevel gear 27 is fixedly sleeved on the bottom of the rotating shaft 28. A bevel gear 26 is fixedly sleeved on one end of the horizontal spiral blade 22. The bevel gear 26 and the bevel gear 27 mesh with each other.

[0029] A spur gear 39 is fixedly sleeved on the top of the vertical spiral blade 29, and a spur gear 40 is fixedly sleeved on the top of the rotating shaft 28.

A motor 15 is fixedly sleeved on the gear housing 13, and the output end of the motor 15 is fixedly connected to one end of the vertical spiral blade 29.

[0030] Specifically, in existing technology, external gas enters the alarm through the air inlet, flows through the chamber containing the core gas sensor, and then naturally flows out from the exhaust port, thus achieving continuous monitoring. Furthermore, to prevent external contaminants from affecting the sensor's detection accuracy and long-term stability, a dust filter 8 is installed at the air inlet to intercept external impurities. However, after prolonged use, the intercepted impurities can clog the filter holes 33 on the dust filter 8, reducing gas flow efficiency and consequently affecting the accuracy of the monitoring results.

[0031] Furthermore, existing technologies often use a rotating brush to clean the surface of the dust filter 8, thus preventing impurities from clogging it. However, during the cleaning process, the brush only sweeps away the impurities adhering to the surface of the dust filter 8, without completely removing them from the vicinity of the air inlet. The impurities that are lifted up are easily carried back to the surface of the dust filter 8 or re-adsorbed around the filter holes 33 by the airflow and their own gravity, resulting in repeated adhesion. This causes the dust filter 8 to become clogged again in a short period of time, resulting in an unsatisfactory cleaning effect. It is difficult to maintain the continuous unobstructed air intake channel, which in turn affects the efficiency of gas entering the sensor chamber and is detrimental to ensuring the accuracy of monitoring results.

[0032] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: Install the alarm body 1 in a suitable location. Outside gas enters the alarm body 1 through the air inlet pipe 3, flows through the gas chamber where the core gas sensor is located, and then flows out naturally from the exhaust pipe 4, thereby achieving continuous monitoring. When the concentration of gas in the air reaches the set critical point, the alarm body 1 automatically issues an alarm signal and remotely pushes the alarm information to the user terminal or monitoring platform to remind personnel to take appropriate measures in a timely manner.

[0033] Furthermore, before the gas enters the gas chamber where the gas sensor is located, it first passes through the dustproof net 8, which filters out impurities in the gas. The filtered impurities adhere to the surface of the dustproof net 8. Similarly, the impurities are also in a hexagonal barrier structure formed by multiple radial plates 10 and multiple scraping cloths 9.

[0034] Every so often, the controller issues a self-cleaning command. First, motor 17 drives eccentric wheel 37 to rotate, using eccentric wheel 37 to press connecting rod 23, causing connecting rod 23 to slide on transverse tube 24, so that multiple ejector pins 38 simultaneously penetrate each filter hole 33, thus pushing out impurities attached to the inner wall of filter hole 33. Then, electric push rod 11 drives radial rod 20 on one side to slide, causing radial plate 10 to move towards the circular through hole in the middle of dustproof net 8. With the cooperation of connecting rod 21 and rotating ring 19, multiple radial rods 20 can slide simultaneously. At the same time, the dust scraper 9 is wound up on take-up and unwinding shaft 34 under the action of spring 36. The unwound part of dust scraper 9 remains taut, thus reducing the volume of the hexagonal barrier structure proportionally. During the reduction process, impurities attached to the surface of dustproof net 8 and those pushed out by ejector pins 38 are gathered to the circular through hole, thus allowing the impurities to enter the conveying range of transverse spiral blade 22. At the same time, the motor 15 drives the vertical spiral blade 29 to rotate, which in turn causes the shaft 28 to rotate under the transmission cooperation of the spur gear 39 and the spur gear 40.

[0035] Next, with the cooperation of bevel gear 27 and bevel gear 26, the transverse spiral blade 22 rotates, which moves the impurities gathered by the hexagonal barrier structure to the bottom of the vertical tube 14. When the impurities reach the bottom of the vertical tube 14, they will move upward under the rotation of the vertical spiral blade 29 until they reach the inclined tube 16. Finally, they fall into the dust box 2 through the inclined tube 16, and then the radial plate 10 returns to its initial position.

[0036] By periodically repeating the above operations, the impurities on the surface of the dustproof net 8 and inside the filter holes 33 are thoroughly removed and effectively transferred, avoiding the problem of repeated adhesion of impurities and short-term re-clogging of the dustproof net 8 in traditional brush cleaning methods. Specifically, by using the ejector pin 38 to penetrate the filter holes 33, the impurities embedded in the inner wall of the filter holes 33 can be ejected, solving the problem that simple surface cleaning is insufficient to remove the blockages inside the holes; the hexagonal barrier structure formed by the radial plate 10 and the scraper cloth 9 gathers the ejected and attached impurities to the transverse spiral blades 22 during the shrinking process, ensuring that the impurities are effectively collected rather than scattered to the surrounding area, fundamentally preventing the phenomenon of impurities falling back into the dustproof net 8 under the action of airflow. Impurities are relayed by the horizontal spiral blades 22 and the vertical spiral blades 29, and finally discharged into the dust box 2 for centralized collection. This realizes the integrated automatic operation of cleaning and impurity removal, which enables the dust screen 8 to remain clean for a long time. This ensures the continuous unobstructed air intake channel and the high efficiency of gas entering the sensor chamber, thereby effectively guaranteeing the accuracy of monitoring results and the long-term reliability of the alarm.

[0037] Furthermore, the dustbin 2 can be kept clean by periodically opening the lid 7 to remove impurities.

[0038] Furthermore, if the radial plate 10 remains in contact with the surface of the dustproof net 8, when the radial plate 10 resets from the circular through-hole towards the edge of the dustproof net 8, if there are new impurities along the reset path, these impurities will be pushed towards the inner wall of the air inlet pipe 3. This results in the impurities being outside the hexagonal barrier structure and unable to be effectively gathered and collected. These impurities pushed outside the barrier structure are difficult to remove in a timely manner during subsequent cleaning, thus weakening the actual effect of the cleaning operation. This makes it difficult for the dustproof net 8 to maintain an ideal clean state, which is not conducive to ensuring the long-term stable and accurate monitoring of the gas sensor.

[0039] Therefore, a sealing plate 35 is provided at the opening of the air intake pipe 3. When the radial plate 10 is reset, the electric push rod 12 will push the fixing ring 18 to move laterally, so that the end of the radial plate 10 is away from the surface of the dustproof net 8. The sealing plate 35 will also slide accordingly to fill the gap caused by the opening. Then the radial plate 10 is reset to the edge of the dustproof net 8 and fits against the surface of the dustproof net 8.

[0040] This avoids pushing impurities towards the inner wall of the intake pipe 3 during the resetting process of the radial plate 10, ensuring that the impurities are always within the controllable range of the hexagonal barrier structure. This allows each cleaning operation to completely gather and transfer the impurities on the surface of the dust screen 8 and in the filter holes 33 to the dust box 2, effectively preventing the residue and accumulation of impurities in the intake pipe 3, and further improving the thoroughness and reliability of the cleaning operation.

[0041] Furthermore, the sealing plate 35 not only meets the movement requirements of the radial rod 20, but also prevents gas from escaping from inside the air inlet pipe 3, maintaining a stable airflow path inside the air inlet pipe 3, and further ensuring that the gas can flow to the dustproof net 8 in a concentrated manner.

[0042] In this embodiment, as Figure 2 and Figure 10 As shown, the alarm body 1 is also equipped with a quick-release structure; The quick-installation structure includes a mounting base 5, with multiple mounting ears 6 arranged circumferentially on the mounting base 5. A plug block 30 is fixedly connected to one side of the alarm body 1. The mounting base 5 has a plug hole that mates with the plug block 30. A plug rod 31 slides vertically through the alarm body 1. A spring 32 is sleeved on the plug rod 31. One end of the spring 32 is fixedly connected to the alarm body 1, and the other end is fixedly connected to the end of the plug rod 31. The plug block 30 has a plug hole that mates with the plug rod 31.

[0043] Specifically, the mounting base 5 is installed on the wall using the mounting ear 6 and bolts. The plug 30 on the alarm body 1 is inserted into the socket in the middle of the mounting base 5. The plug rod 31 is inserted into the socket of the plug 30 under the action of the spring 32, thus installing the alarm body 1. When maintenance or cleaning of the alarm body 1 is required, simply pull the plug rod 31 to disengage it from the socket of the plug 30, and the alarm body 1 can be removed. This achieves quick installation and removal of the alarm body 1. Through the plug-in cooperation between the plug 30 and the mounting base 5, combined with the automatic locking of the plug rod 31 under the action of the spring 32, there is no need for complicated operations such as tightening bolts with tools. When disassembling, simply pull the plug rod 31 to release the lock and remove the alarm body 1. The operation is simple and quick, significantly reducing the difficulty and time cost of disassembly and assembly, and greatly improving the convenience and work efficiency of the alarm in daily maintenance, repair and cleaning.
