Description

Technical Field

[0001] The present invention belongs to the technical field of gas safety equipment, and particularly relates to a safety gas alarm device. Background Art

[0002] Gas is a combustible and toxic gas. When using a safety gas alarm device to detect gas in the air, an alarm will be triggered when gas is detected, thereby alerting people and preventing them from inhaling gas and getting poisoned.

[0003] The Chinese invention application with the application number "CN201410149263.9" relates to a gas alarm device. A gas inlet hole is provided on the alarm surface of the frame body of the gas alarm device, and a light-emitting device is provided at a position close to one long side of the alarm surface. When the gas alarm device is assembled on the visor of a helmet and worn on the head by the person being alerted, the alarm surface of the gas alarm device faces downward and the light-emitting device is located at the front end of the visor. The concentration of the gas to be detected in the gas introduced through the gas inlet hole is measured by the gas detection device in the frame body. When the light-emitting device emits alarm light, the person being alerted can see the alarm light.

[0004] The above application can detect the concentration of gas, and the alarm light is more easily noticed. However, when using the alarm device in some humid environments, the diffusion rate of humid air is slow, which may cause the alarm device to fail to quickly detect gas, shortening the time for people to evacuate or take measures. Moreover, when humid air enters the alarm device, it may cause the internal electronic components of the alarm device to be damaged by moisture. Summary of the Invention

[0032] An air inlet drying mechanism 4 is provided on the outer surface of the cavity tube 36. The air inlet drying mechanism 4 includes a fan blade 41.

[0035] The shaking assembly 45 includes a vibration spring 451 and a contact wheel 452. The contact wheel 452 is in contact with the inner wall of the water collecting bin 48.

When the inner cavity of the fan blade 41 is filled with calcium chloride particles, the loosening rod 46 is in contact with the calcium chloride particles.

[0037] A water outlet pipe 481 is fixedly connected to the bottom end of the water collecting bin 48. The bottom end of the water outlet pipe 481 is located outside the device body 1. The inner cavities of the water collecting bin 48 and the water outlet pipe 481 are in communication.

[0038] A gas detector 7 is fixedly connected to the center of the inner cavity of the fixed tube 21. A ventilation plate 22 is fixedly connected to the side of the fixed tube 21 away from the motor 23. An alarm lamp 6 is fixedly connected to the top end of the device body 1. The gas detector 7 and the alarm lamp 6 are electrically connected.

[0039] The ventilation component 42 includes a water outlet plate 421, a side ventilation plate 422, and a front ventilation plate 423. The water outlet plate 421 is fixedly connected to one side of the fan blade 41 close to the raised block 44 and is located inside the water collecting bin 48. The side ventilation plate 422 is fixedly connected to the side where the fan blade 41 inclines towards the material guiding box 33, and the front ventilation plate 423 is fixedly connected to the side of the fan blade 41 away from the material guiding box 33;

[0040] The working principle and beneficial effects of the above technical solution are as follows: When used for the first time, open the blocking head 311, and then add calcium chloride particles into the inner cavity of the storage box 31. The calcium chloride particles in the inner cavity of the storage box 31 fall into the inner cavity of the blanking pipe 32;

[0041] Start the motor 23 to drive the T-shaped connecting pipe 35 on its output shaft to rotate, and then drive the cavity pipe 36 to rotate through the T-shaped connecting pipe 35. When the cavity pipe 36 rotates, it drives the anti-slip transmission belt 37 to operate, drives the speed reducer 38 to operate through the anti-slip transmission belt 37, and then drives the blanking plate 34 to rotate at a reduced speed through the speed reducer 38. When the blanking plate 34 rotates, the calcium chloride particles in the inner cavity of the blanking pipe 32 are conveyed into the inner cavity of the material guiding box 33. The calcium chloride particles are squeezed into the inner cavities of the cavity pipe 36 and the fan blade 41 along the material guiding box 33, and are thrown into the inner cavity of the fan blade 41 by the centrifugal force generated by the high-speed rotation of the cavity pipe 36 driving the fan blade 41 until the inner cavity of the fan blade 41 is filled;

[0042] When in formal use, refer to Figure 7 , start the motor 23 to drive the T-shaped connecting pipe 35 to rotate clockwise, thereby driving the cavity pipe 36 to rotate clockwise. The cavity pipe 36 drives the fan blade 41 to rotate clockwise, thereby generating suction. The external air is filtered by the dust filter pipe 51 and then sucked into the inner cavity of the movable pipe 43, and then enters the inner cavity of the fixed pipe 21 through the movable pipe 43, so as to contact the gas detector 7. The gas detector 7 detects the gas in the air. Then the air is discharged through the ventilation plate 22. When the gas detector 7 detects gas, the device body 1 emits an alarm sound and flashes an alarm through the alarm lamp 6, thereby realizing that in a humid environment, the air with a slow external diffusion speed will be sucked into the inner cavity of the fixed pipe 21 to contact 7, avoiding the slow air diffusion and thus being unable to quickly detect the gas;

[0043] Since the fan blade 41 rotates clockwise during the process of generating suction, the side ventilation plate 422 and the front ventilation plate 423 become the air inlet surfaces. As a result, the calcium chloride particles in the inner cavity of the fan blade 41 can come into contact with the moisture in the air through the side ventilation plate 422 and the front ventilation plate 423. After contacting the moisture, the calcium chloride particles turn into an aqueous solution. Due to the clockwise rotation of the fan blade 41, the aqueous solution in the inner cavity of the fan blade 41 is thrown in the direction away from the side ventilation plate 422 and the front ventilation plate 423 and in the direction of the water outlet plate 421. Since both sides of the fan blade 41 away from the side ventilation plate 422 and the front ventilation plate 423 are solid, the aqueous solution cannot be discharged. Therefore, it can only be discharged along the water outlet plate 421 into the inner cavity of the water collection bin 48 and discharged along the water outlet pipe 481. Thus, the aqueous solution can be automatically thrown into the inner cavity of the water collection bin 48 and discharged, preventing the aqueous solution from dripping into the inner cavity of the movable pipe 43 and causing the gas detector 7 to be damaged by moisture.

[0044] As the cavity tube 36 continues to rotate, it drives the feeding plate 34 to rotate slowly, continuously replenishing the calcium chloride particles into the inner cavity of the fan blade 41. Due to the pressing of the calcium chloride particles by the feeding plate 34 and the centrifugal force generated when the cavity tube 36 drives the fan blade 41 to rotate, the calcium chloride particles are stressed and can tightly fill the inner cavity of the fan blade 41. Thus, it realizes the automatic replenishment of the reduced calcium chloride particles, ensuring continuous dehumidification during continuous use.

[0045] When the calcium chloride particles in the storage box 31 decrease, the staff can replenish the calcium chloride particles into the inner cavity of the storage box 31.

[0046] When the fan blade 41 rotates, it drives the jitter assembly 45 to move. When the contact wheel 452 contacts the protrusion block 44, the contact wheel 452 moves towards the fan blade 41 and drives the loosening rod 46 to move in the inner cavity of the device body 1, and the vibration spring 451 contracts. When the contact wheel 452 separates from the protrusion block 44, the vibration spring 451 releases its elasticity and drives the loosening rod 46 to move and reset in the inner cavity of the device body 1. This process repeats continuously, and in cooperation with the continuous rotation of the cavity tube 36, it can drive the loosening rod 46 to reciprocate in the inner cavity of the fan blade 41, thereby loosening the calcium chloride particles and increasing the contact surface between the calcium chloride particles and the air, thus improving the moisture-proof effect.

[0047] Embodiment 2: As Figures 1 to 3As shown in the figure, an embodiment of the present invention provides a safety gas alarm device. A filtering mechanism 5 is provided on one side of the movable pipe 43 away from the device body 1. The filtering mechanism 5 includes a dust filtering pipe 51. The dust filtering pipe 51 is fixedly connected to one side of the movable pipe 43 away from the device body 1. A fixed scraper 52 is fixedly connected to one side of the device body 1 close to the dust filtering pipe 51. The fixed scraper 52 is attached to the outer surface of the dust filtering pipe 51. A connecting plate 53 is fixedly connected to one side of the fixed scraper 52 away from the device body 1. One side of the connecting plate 53 close to the fixed scraper 52 is attached to the dust filtering pipe 51;

[0048] The working principle and beneficial effects of the above technical solution are as follows: When air enters the inner cavity of the movable pipe 43 from the dust filtering pipe 51, the dust in the air is blocked by the dust filtering pipe 51. Since the movable pipe 43 is fixedly connected to the dust filtering pipe 51, the dust filtering pipe 51 can be driven to rotate. Then, by attaching the outer surface of the dust filtering pipe 51 to the fixed scraper 52, the dust on the outer surface of the dust filtering pipe 51 can be scraped off by the fixed scraper 52. Thus, the air entering the inner cavity of the movable pipe 43 is filtered by the dust filtering pipe 51, avoiding the situation that dust enters the inner cavities of the movable pipe 43 and the fixed pipe 21 and the surface of the gas detector 7, which affects the normal use. The accumulated dust is scraped off by the fixed scraper 52, avoiding the influence of dust accumulation on the air flow rate.

[0049] Working principle and usage process: Before the initial use, pull out the plugging head 311, then add calcium chloride particles into the inner cavity of the storage box 31. Then start the motor 23 to drive the T-shaped connecting pipe 35 to rotate. The T-shaped connecting pipe 35 drives the cavity pipe 36 to rotate. The rotation of the cavity pipe 36 drives the anti-slip transmission belt 37 to operate. Then, the anti-slip transmission belt 37 drives the reduction gear 38 to operate. The reduction gear 38 then drives the blanking plate 34 to operate at a reduced speed. During the operation of the blanking plate 34, the calcium chloride particles in the inner cavity of the storage box 31 will enter the inner cavity of the guide box 33 along the blanking pipe 32, and then enter the inner cavity of the cavity pipe 36 through the guide box 33;

[0050] At this time, the calcium chloride particles are thrown into the inner cavity of the fan blade 41 by the rotation of the cavity pipe 36 and fill the inner cavity of the fan blade 41;

[0051] When in formal use, refer to Figure 7 , the motor 23 drives the cavity pipe 36 to rotate clockwise, thereby driving the fan blade 41 to rotate clockwise at a high speed, generating suction, so as to suck the external air into the inner cavity of the movable pipe 43 after filtering through the dust filtering pipe 51, and enter the inner cavity of the fixed pipe 21 along the movable pipe 43. The gas detector 7 in the inner cavity of the fixed pipe 21 detects the air. Then the air is discharged through the ventilation plate 22. When the gas detector 7 detects gas, the device body 1 emits an alarm sound, and the alarm lamp 6 flashes for alarm;

[0052] At this time, since the fan blade 41 rotates clockwise, the calcium chloride particles in the inner cavity of the fan blade 41 come into contact with the air through the side ventilation plate 422 and the front ventilation plate 423, and absorb the moisture in the air. After the calcium chloride particles absorb the moisture, they will become an aqueous solution. However, since the fan blade 41 rotates clockwise at a high speed, the aqueous solution in the inner cavity of the fan blade 41 will be thrown towards the two sides of the fan blade 41 away from the side ventilation plate 422 and the front ventilation plate 423 and the direction of the water outlet plate 421. However, since both of these two sides are solid, the aqueous solution is blocked and can only be discharged along the fan blade 41 from the water outlet plate 421 into the inner cavity of the water collection bin 48, and then the aqueous solution is discharged along the water outlet pipe 481;

[0053] And when the fan blade 41 rotates at a high speed, the contact wheel 452 will contact the raised block 44. When the contact wheel 452 contacts the raised block 44, it will be pushed towards the direction of the fan blade 41 and drive the loosening rod 46 to move in the inner cavity of the fan blade 41. At this time, the vibration spring 451 contracts and accumulates elasticity. When the contact wheel 452 separates from the raised block 44, the vibration spring 451 releases its elasticity and drives the contact wheel 452 away from the fan blade 41. This cycle makes the shaking assembly 45 continuously move, thereby driving the loosening rod 46 to continuously move in the inner cavity of the fan blade 41 to loosen the calcium chloride particles;

[0054] When the fan blade 41 rotates, it will drive the movable pipe 43 to rotate. By driving the rotation of the movable pipe 43, the dust filter pipe 51 rotates. And since the outer surface of the dust filter pipe 51 is attached to the fixed scraper 52, the fixed scraper 52 can scrape off the dust on the outer surface of the dust filter pipe 51;

[0055] And by driving the rotation of the blanking plate 34 through the cavity pipe 36, it is possible to continuously supplement the calcium chloride particles in the inner cavity of the fan blade 41 during use.

[0056] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
