DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Please refer to Figures 1-6The utility model provides the following technical scheme: A kind of exhaust gas detection device for environmental supervision, including monitoring box 1, the side of monitoring box 1 is communicated with air inlet pipe 2, the bottom of monitoring box 1 is installed with support frame 3, monitoring box 1 is fixedly installed with cross bar 4 on the outer wall of one side of air inlet pipe 2, and the outer wall of the other end of support frame 3 is sleeved with movable sleeve 5;

[0025] Monitoring box 1 is arranged in the area needing to be monitored, and when working, the external gas enters the inside of monitoring box 1 through air inlet pipe 2, at this time, the monitoring components arranged in the inside of monitoring box 1 can detect the entering gas, so that the surrounding environmental condition can be effectively analyzed, since it is prior art and is irrelevant to the core of the present technical scheme, the present technical scheme does not make too many statements, please refer to the authorized announcement No.CN218331454U for details: a kind of exhaust gas detection device for environmental supervision.

[0026] The outer wall of one side of movable sleeve 5 is bonded with connecting rod 6, the top end of connecting rod 6 is fixedly connected with guard plate 7, and the through hole inside of guard plate 7 is installed with guard net 8, and one side of guard net 8 is attached to the port of air inlet pipe 2.

[0027] Preferably, the through hole one side outer wall of guard plate 7 is fixedly installed with port ring 71, the outer wall of the other side of through hole is fixedly installed with tail ring 72, a circle of sealing grooves 73 is formed on the inner wall of port ring 71 at equal intervals, and a circle of clamping holes 74 is formed on the inner wall of the through hole of guard plate 7.

[0028] A circle of sealing strips 81 is installed on the outer ring wall of guard net 8 at equal intervals, and sealing strip 81 is simultaneously connected with sealing groove 73 and clamping hole 74 when guard net 8 is installed in the inside of guard plate 7.

[0029] Specifically, when guard net 8 is connected with guard plate 7, sealing strip 81 on the outer wall of guard net 8 is aligned with clamping hole 74 and sealing groove 73 on guard plate 7 and port ring 71, and clamping hole 74 and sealing groove 73 are in alignment when guard plate 7 and port ring 71 are connected together.

[0030] In this way, sealing strip 81 is simultaneously connected with clamping hole 74 and sealing groove 73 when being installed, so that guard net 8 can be fixed in the inside of guard plate 7 after being installed.

[0031] Preferably, connecting rod 6 is made of rubber material, and the maximum diameter size of air inlet pipe 2 is adapted to the inner diameter of the through hole of guard plate 7 and tail ring 72.

[0032] Specifically, when guard plate 7 is connected and pulled, guard plate 7 drives connecting rod 6 to deform, so that the positional relationship between guard plate 7 and air inlet pipe 2 can be further adjusted, so that air inlet pipe 2 can be accurately connected into the through hole of guard plate 7.

[0033] Preferably, the outer wall of the horizontal rod 4 is fixed with a sleeve ring 41, and a circle of convex points 42 is installed on the outer wall of the sleeve ring 41 at equal intervals; the inner wall of the movable sleeve 5 is in movable contact with the outer wall of the horizontal rod 4, and a circle of annular grooves 51 is formed on the inner wall of the movable sleeve 5;

[0034] The sleeve ring 41 is arranged inside the annular groove 51, and the convex points 42 on the outer wall of the sleeve ring 41 are in abutment with the inner wall of the annular groove 51; the convex points 42 are made of rubber.

[0035] When the movable sleeve 5 is adjusted to rotate on the outer wall of the horizontal rod 4, the movable sleeve 5 will drive the annular groove 51 to rotate synchronously; when the adjustment of the movable sleeve 5 is completed, the abutment of the convex points 42 will position the movable sleeve 5, so that the movable sleeve 5 can be fixed at the adjusted position.

[0036] In specific use, first, the movable sleeve 5 needs to be rotated, which will drive the guard plate 7 to move along the predetermined trajectory through the designed connecting rod 6 until the guard plate 7 is accurately positioned on one side of the air inlet pipe 2. Then, the guard plate 7 needs to be pulled moderately, which will make the connecting rod 6 experience a controllable elastic deformation process, which is designed to ensure the smoothness and safety of operation. In this process, the guard plate 7 is rotated again to align the guard plate 7 with the port of the air inlet pipe 2, and then the through hole reserved on one side of the guard plate 7 is inserted into the port of the air inlet pipe 2.

[0037] Once the guard plate 7 is correctly positioned, the pulling force on the guard plate 7 can be released, and at this time, the connecting rod 6 resets by virtue of its rubber properties. This resetting action not only ensures that the guard plate 7 is stably pushed forward, but also ingeniously utilizes the elastic potential energy of the connecting rod 6 to tightly fit and fix the air inlet pipe 2 on the outer wall of the protective net 8, forming a firm and reliable protective barrier.

[0038] The use of the protective net 8 adds an important protective layer for the safe use of the entire air inlet pipe 2. The fine mesh design can effectively block the potential invasion path of external flying insects, dust and other larger foreign matters through the air inlet pipe 2, thereby greatly reducing the risk of interference or damage to the internal components of the monitoring box 1 by these unfavorable factors. This innovative design not only improves the overall protection performance of the monitoring box 1, but also effectively safeguards the safety and stability of its internal environment, providing a solid foundation for continuous and accurate monitoring work.

[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
