[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0030] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0032] First, open the valve on the exhaust nozzle of the gas collection tube, then push the piston rod to drive the piston to move to discharge the air inside the gas collection tube, then pull the piston rod in the designated area to drive the piston to move to extract air, and when the gas collection tube is completed, close the valve on the exhaust nozzle.

[0033] In the related art, it is inconvenient to collect gas in the environment. Generally, the gas is collected through a gas collection tube similar to a needle tube, and a mobile mechanism drives several gas collection tubes to collect multiple groups of gases at the same time. This is convenient and efficient. However, the mobile mechanism is always exposed to the external space and is integrated with several gas collection tubes. As a result, the mobile mechanism is not used for a long time and dust accumulates, affecting the drive. It is also inconvenient to disassemble, clean, repair and replace the mobile mechanism after being bumped and damaged. There are certain limitations.

[0034] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides an environmental detection gas collection device. When gas collection is required, it is only necessary to insert the block 25 into the slot 26 on the connecting plate 13, and then fit the mounting seat 21 and the base 11 into place, and then rotate the screw 22 to insert it into the fixing slot 23 for fixation. The connecting plate 13 and several gas collection pipes 12 are driven by the moving mechanism 24 to make the piston inside the gas collection pipe 12 move relatively to exhaust gas. When the moving mechanism 24 is not used for a long time and is covered with dust or damaged by bumps, the screw 22 is rotated in the opposite direction to disengage from the fixing slot 23 to release the fixation and remove the adjustment component 2, thereby facilitating the cleaning and maintenance of the moving mechanism 24.

[0035] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0036] Combination Figure 1-Figure 4 The embodiment of the present application provides an environmental detection gas collection device, including a main body component 1; the main body component 1 includes: a base 11, on which a gas collection pipe 12 is arranged; a connecting plate 13, which is arranged on the gas collection pipe 12; an adjustment component 2 is arranged on the base 11, and the adjustment component 2 includes: a mounting seat 21, which is arranged on the base 11; a screw 22, which is threadedly connected to the mounting seat 21; a fixing groove 23, which is opened on the base 11, and the screw 22 is inserted into the fixing groove 23; a moving mechanism 24, which is arranged on the mounting seat 21; a block 25, which is arranged on the moving mechanism 24; a slot 26, which is opened on the connecting plate 13, and the block 25 is inserted into the slot 26.

[0037] First, open the valve on the suction nozzle of the gas collection pipe 12, then push the piston rod to drive the piston to move to discharge the air inside the gas collection pipe 12, then pull the piston rod in the designated area to drive the piston to move and extract the air, and when the gas collection pipe 12 has collected all the air, close the valve on the suction nozzle. When collecting gas in this scheme, you only need to insert the block 25 into the slot 26 on the connecting plate 13, then fit the mounting seat 21 and the base 11 into place, and then rotate the screw 22 to insert it into the fixing slot 23 for fixing, and drive the connecting plate 13 and several gas collection pipes 12 to move through the moving mechanism 24 so that the piston inside the gas collection pipe 12 moves relatively to extract air. When the moving mechanism 24 is not used for a long time and is covered with dust or damaged by bumps, the adjusting component 2 can be removed by rotating the screw 22 in the opposite direction to disengage from the fixing slot 23 to release the fixation, thereby facilitating the cleaning and maintenance of the moving mechanism 24.

[0038] In some embodiments, the moving mechanism 24 includes: a motor 241, which is arranged on the mounting base 21; a worm 242, which is arranged on the output end of the motor 241; a screw 243, which is rotatably connected to the mounting base 21; a worm wheel 244, which is arranged on the screw 243, and the worm wheel 244 and the worm 242 are meshed; an adjustment plate 245, which is threadedly connected to the screw 243, and the block 25 is installed on the adjustment plate 245.

[0039] The rotation of the output end of the motor 241 drives the rotation of the worm 242, which drives the rotation of the worm wheel 244. The rotation of the worm wheel 244 drives the rotation of the screw rod 243. The rotation of the screw rod 243 drives the movement of the adjustment plate 245, thereby conveniently driving the connection plate 13 and several gas collection pipes 12 to move so that the internal piston moves relative to each other to extract gas.

[0040] In some embodiments, a protective component 3 is provided on the mounting base 21, and the protective component 3 includes: a protective cover 31, which is provided on the mounting base 21; an opening 32, which is opened on the protective cover 31; a baffle 33, which is slidably connected to the protective cover 31; a magnetic strip 34, which is provided on the baffle 33; and an iron strip 35, which is provided on the protective cover 31.

[0041] When the gas needs to be collected, the baffle 33 is moved into the protective cover 31 to open the opening 32, and the magnetic strip 34 on the baffle 33 is adsorbed and fixed with the iron strip 35 inside the protective cover 31, thereby not affecting the movement of the adjustment plate 245 at the opening 32. When the gas collection is completed, the adjustment plate 245 is driven to move to the specified position through the rotation of the screw rod 243, and then the baffles 33 are moved close to each other to be adsorbed and fixed to close the opening 32 for protection against dust.

[0042] In some embodiments, the protective component 3 also includes: a pointer 36, which is arranged on the protective cover 31; a punctuation mark 37, which is arranged on the adjustment plate 245. When the device is not in use, the adjustment plate 245 is driven to move by the rotation of the screw rod 243. When the punctuation mark 37 corresponds to the pointer 36, the device is stopped, thereby facilitating the movement of the baffle 33 to close the protective cover 31.

[0043] In some embodiments, a disassembly assembly 4 is provided on the protective cover 31 , and the disassembly assembly 4 includes: a second screw rod 41 threadedly connected to the protective cover 31 ; a groove body 42 opened on the mounting seat 21 , and the second screw rod 41 is inserted into the groove body 42 .

[0044] During installation, the protective cover 31 is placed on the surface of the mounting seat 21, and then the screw rod 41 is rotated to thread the protective cover 31 and insert it into the groove body 42 for fixation. This facilitates the protective cover 31 to be stably fixed on the mounting seat 21 to protect the moving mechanism 24 from dust. When the adjustment component 2 is disassembled, the screw rod 41 is rotated in the reverse direction to disengage from the groove body 42 to release the fixation and remove the protective cover 31, thereby facilitating the maintenance of the moving mechanism 24.

[0045] In some embodiments, the disassembly assembly 4 also includes: a positioning rod 43, which is arranged on the protective cover 31; a positioning groove 44, which is opened on the mounting seat 21, and the positioning rod 43 is inserted into the positioning groove 44. When the protective cover 31 needs to be installed, the positioning rod 43 on one side of the protective cover 31 is aligned and inserted into the positioning groove 44 on the surface of the mounting seat 21 to avoid displacement during the installation process.

[0046] In some embodiments, a guide block 5 is provided on one side of the card block 25 . When the card block 25 needs to be inserted into the card slot 26 , the guide block 5 is tapered, so the card block 25 can be inserted into the card slot 26 quickly and accurately.

[0047] In some embodiments, the width of the adjustment plate 245 is equal to the width of the opening 32 , so that the adjustment plate 245 is more stable during the movement driven by the rotation of the screw rod 243 .
