Description
Technical Field
[0001] This utility model relates to the field of gas collection technology, and more specifically to an environmental gas collection device. Background Technology
[0002] With the acceleration of industrialization and urbanization, air pollution has become an increasingly prominent problem, making accurate and efficient monitoring of ambient gases a crucial task in environmental protection. As the front-end equipment for gas detection and analysis, the performance of ambient gas sampling devices directly affects the accuracy of gas component identification and concentration analysis. Traditional gas detection instruments primarily rely on gas sensors to detect the types and concentrations of gases present in the environment; their core component is the gas sensor, which is sensitive to the target gas. Gas sensors operate by reacting with the gas being measured, generating an electrical signal proportional to the gas concentration, and are widely used in environmental monitoring, industrial safety, and other fields.
[0003] As shown in the prior art published in CN220207204U, although the prior art, through the design of the docking structure, makes the connection between the connector and the air outlet more stable, avoiding excessive air pressure at the air outlet that could cause the connector to detach and leak air; and through the internal design of the connector, the gas collecting ball can automatically seal internally after being pulled out, avoiding excessive and cumbersome operations, thereby improving the convenience of the device, this prior art requires the operator to be inside the gas environment when collecting gas, making the operator susceptible to gas hazards, which affects the operator's operational safety. Summary of the Invention
[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides an environmental gas collection device. By extending the operating path with a pull rope, it is moved away from the gas collection environment to avoid gas hazards and safety. Subsequently, the operating pin separates from the reset hole, freeing the pressure pin from its position. Then, the rebound of the first spring pushes the pressure pin into contact with a tactile switch, activating the collection device. When the pin is engaged in the reset hole, the pressure pin separates from the tactile switch, thus shutting down the collection device. This improves the convenience of operating the collection device and effectively enhances operational safety, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an environmental gas collection device, comprising a gas pipe, wherein a gas collection element is provided outside the gas pipe for collecting gas, and the gas pipe is extended away from the gas collection environment through an extension element; The extension includes a packaging cylinder, which is provided with a first spring, a pressure post and a tactile switch from front to back. The first spring has a connecting rope for connecting the pressure post inside. The front end of the connecting rope passes through the packaging cylinder and extends to the outside of the front end of the packaging cylinder. A pulling tube for connecting the packaging cylinder is sleeved on the outside of the connecting rope. The front end of the pulling tube has a reset hole and a pressing hole. The reset hole and the pressing hole are arranged in a cross shape. A locking post for connecting the connecting rope is provided inside the reset hole.
[0006] In a preferred embodiment, the collection device includes a duct and a connecting pipe. The duct is fixedly connected to the rear side of the air pipe, and a fan is installed inside the duct. The connecting pipe is threaded to the outside of the rear end of the air pipe, and an air bladder is fixedly connected to the front end of the connecting pipe. The air bladder is provided with an opening and closing device for adjusting gas collection.
[0007] In a preferred embodiment, the opening and closing component includes an adjusting column disposed in a branch pipe, a sealing plug installed at the front end of the adjusting column, the sealing plug being disposed inside the airbag, a fixing plate installed at the rear end of the adjusting column, and a fixing ring sleeved on the outside of the adjusting column being installed inside the branch pipe, the fixing ring having multiple through holes arranged in a ring array on its outside, and a second spring sleeved on the outside of the adjusting column being provided between the fixing ring and the fixing plate. The front end of the trachea is provided with a contact plate located behind the fixing plate, and multiple supports for connecting the trachea are installed on the outside of the contact plate.
[0008] In a preferred embodiment, a counterweight bracket is fitted over the trachea, and multiple ring shells arranged in a circular array are installed on the outside of the counterweight bracket. The encapsulation cylinder and the tactile switch are both installed on the front side of the counterweight bracket.
[0009] In a preferred embodiment, a dustproof net is installed inside the rear end of the duct, and the dustproof net is located on the rear side of the fan.
[0010] In a preferred embodiment, the diameter of the fixing plate is equal to the diameter of the contact plate, and the diameter of the fixing plate is smaller than the outer diameter of the fixing ring.
[0011] The technical effects and advantages of this utility model are as follows: The operating path is extended by pulling the rope to move it away from the gas collection environment and avoid gas hazards. Then, the operating pin separates from the reset hole, so that the pressure pin is not restricted. Then, the rebound of the first spring pushes the pressure pin to contact the tactile switch, and the tactile switch starts the operation of the collection device. When the pin is locked into the reset hole, the pressure pin separates from the tactile switch, thereby shutting down the collection device. This improves the convenience of operating the collection device and effectively enhances the safety of operation. Attached Figure Description

[0014] 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.
[0015] Refer to the instruction manual appendix Figure 1-5 This utility model provides an environmental gas collection device, including a gas tube 1. The gas tube 1 is provided with a gas collection component on its exterior, and the gas tube 1 is extended away from the gas collection environment through an extension component. The extension component includes a sealing cylinder 2. The sealing cylinder 2 is provided with a first spring 3, a pressure column 4 and a tactile switch 5 from front to back. The first spring 3 is provided with a connecting rope 6 for connecting the pressure column 4. The front end of the connecting rope 6 passes through the sealing cylinder 2 and extends to the exterior of the front end of the sealing cylinder 2. A pulling tube 7 for connecting the sealing cylinder 2 is sleeved on the outside of the connecting rope 6. The front end of the pulling tube 7 is provided with a reset hole 8 and a pressing hole 9. The reset hole 8 and the pressing hole 9 are arranged in a cross shape. The reset hole 8 is provided with a locking post 10 for connecting the connecting rope 6 inside.
[0016] When collecting gas using the collection device inside the trachea 1, the operator needs to place the collection device on the trachea 1 inside the corresponding environment. To avoid the gas in the environment from harming the operator, the operator can hold the traction tube 7 and throw the collection device into the gas environment. This can prevent the operator from entering the gas environment and avoid the gas from harming the operator's body. To prevent damage to the sample when it is thrown, a counterweight bracket 24 is fitted over the air tube 1. Multiple annular shells 25 arranged in a circular array are mounted on the outside of the counterweight bracket 24. The encapsulation cylinder 2 and the tactile switch 5 are both installed on the front side of the counterweight bracket 24. This design uses multiple annular shells 25 to shield and protect the sample, preventing damage from the impact of being thrown and ensuring its integrity. Furthermore, the weight of the counterweight bracket 24 effectively counterbalances the sample, preventing it from moving when the connecting rope 6 is pulled. Meanwhile, after the sampler is placed in the gas environment, the outer clamping post 10 is pulled to straighten the connecting rope 6. The connecting rope 6, together with the pressure post 4, moves outward and compresses the first spring 3, thus moving the clamping post 10 away from the reset hole 8. Then, the clamping post 10 is rotated to align with the pressing hole 9. In this way, the rebound force of the first spring 3 can be used to push the pressure post 4 and the connecting rope 6 inward. The pressure post 4 contacts the tactile switch 5, while the clamping post 10 moves synchronously into the pressing hole 9. The tactile switch 5 then starts the sampler to run. The gas collection device includes a duct 11 and a connecting pipe 12. The duct 11 is fixedly connected to the rear side of the air pipe 1, and a fan 13 is installed inside the duct 11. The connecting pipe 12 is threaded to the outside of the rear end of the air pipe 1, and an airbag 15 is fixedly connected to the front end of the connecting pipe 12. The airbag 15 has an opening and closing device for adjusting gas collection. Thus, the fan 13 can be activated to transport external gas through the duct 11, air pipe 1, and connecting pipe 12 to the airbag 15, where the gas is collected and stored. To prevent dust from entering the airbag 15 and causing contamination, a dustproof net 14 is installed inside the rear end of the duct 11, located behind the fan 13. This dustproof net 14 can block dust and other impurities, thus preventing them from entering the airbag 15 and causing contamination.
[0017] After the gas collection is completed, the staff pulls the clamping post 10 outward into the reset hole 8 to separate the pressure post 4 from the tactile switch 5, thereby turning off the blower 13 and stopping the gas collection. Then, the staff pulls the pulling rope to pull the entire collection device out of the gas environment, thereby improving the safety of the staff during gas collection.
[0018] To prevent gas leakage, the gas delivery to the airbag 15 is regulated by an opening and closing mechanism. The opening and closing mechanism includes an adjusting column 16 located inside the connecting tube 12. A sealing plug 17 is installed at the front end of the adjusting column 16 and is located inside the airbag 15. A fixing plate 18 is installed at the rear end of the adjusting column 16. A fixing ring 19 is installed inside the connecting tube 12 and sleeved on the outside of the adjusting column 16. Multiple through holes 20 arranged in a ring array are opened on the outside of the fixing ring 19. A second spring 21 is provided between the fixing ring 19 and the fixing plate 18 and sleeved on the outside of the adjusting column 16. A contact plate 22 located behind the fixing plate 18 is provided inside the front end of the air tube 1. Multiple support pillars 23 for connecting the air tube 1 are installed on the outside of the contact plate 22. In this way, when the rotating connecting tube 12 is separated from the air tube 1, the second spring 21 rebounds and resets, and pushes the adjusting column 16 outward by the fixing plate 18. At the same time, the adjusting column 16 and the sealing plug 17 seal the connecting tube 12, thereby sealing the airbag 15 and preventing the airbag 15 from leaking.
[0019] Furthermore, the diameter of the fixing plate 18 is equal to the diameter of the contact plate 22, and the diameter of the fixing plate 18 is smaller than the outer diameter of the fixing ring 19. This allows gas to flow inside the gas pipe 1 and the connecting pipe 12, thereby effectively preventing the fixing plate 18 and the fixing ring 19 from obstructing gas flow.
[0020] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
