Description

Technical Field

[0001] This utility model relates to the field of environmental science, specifically a portable waste gas collection device. Background Technology

[0002] The exhaust gas collector draws in ambient air at a constant or adjustable flow rate using an electric motor-driven air pump. The airflow then passes through a collection unit containing a specific adsorption medium, where target pollutants are selectively captured and concentrated.

[0003] When using exhaust gas collectors, a series of operations such as removal, unfolding, and tightening must be completed manually, which greatly reduces the deployment efficiency of field monitoring. At the same time, the installation process relies entirely on manual operation, which can easily introduce stability risks due to factors such as the tripod not being fully unfolded or the locking mechanism not being tightened. This may cause the instrument to shake or even tip over during sampling, which not only endangers the safety of the equipment, but also directly affects the accuracy and reliability of the collected data due to changes in sampling height or vibration interference. Therefore, a portable exhaust gas collection device is proposed to address the above problems. Utility Model Content

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 scope of protection of the present utility model.

[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a portable exhaust gas collection device. (Refer to...) Figure 1 and Figure 2A portable exhaust gas collection device includes a housing 1, a shoulder strap 101 fixedly mounted on the surface of the housing 1, two lids 102 slidably connected to the top of the housing 1, a storage box 103 slidably connected inside the housing 1, an exhaust gas collector body 104 disposed inside the storage box 103, and a lifting mechanism 2 disposed on the surface of the lids 102, which works in conjunction with the storage box 103; wherein the exhaust gas collector body 104 includes an air circuit system, a power system, a control system and an auxiliary system, etc., which are existing technologies and will not be described in detail here; The lifting mechanism 2 includes two support rods 201 rotatably mounted on both sides of the two box covers 102. One end of each support rod 201 is rotatably connected to the surface of the box body 1. Fixed rods 202 are fixedly connected to both sides of the two box covers 102. Transmission rods 203 are rotatably sleeved on the surface of each fixed rod 202. Two first rotating rods 204 are rotatably connected to both sides of the box body 1. One end of each transmission rod 203 is rotatably sleeved on the surface of the two first rotating rods 204. One end of each first rotating rod 204 penetrates the box body 1 and is rotatably connected to the interior of the box body 1. A first connecting rod 205 is fixedly sleeved at one end, and a second connecting rod 206 is rotatably connected to one end of the first connecting rod 205. One end of each of the two second connecting rods 206 is rotatably mounted on both sides of the placement box 103. A first sector gear 207 is fixedly sleeved at one end of one of the first rotating rods 204, and a second sector gear 208 is fixedly sleeved at one end of the other first rotating rod 204. The surface of the first sector gear 207 meshes with the surface of the second sector gear 208. A support assembly 3 is provided on the surface of the box body 1. The support assembly 3 is used in conjunction with the box cover 102. When needed for outdoor use, the case 1 can be carried using the shoulder strap 101. Upon arrival at the destination, the case 1 is placed on a stable surface, and the two case lids 102 are pushed to the sides. The case lids 102 move the support rod 201 and the transmission rod 203. The support rod 201 provides support and stability to the case lids 102 as they move. The movement of the transmission rod 203 causes the first rotating rod 204 to rotate. Through the stabilization of the first sector gear 207 and the second sector gear 208, the first rotating rod 204 drives the first connecting rod 205 to rotate upward. The first connecting rod 205 pushes the placement box 103 upward through the second connecting rod 206, thereby pushing the two side covers 102 to move the placement box 103 and the exhaust gas collector body 104 upward inside the box 1. The support component 3 supports the cover 102, thereby positioning the placement box 103 so that it can resist the downward pressure of the exhaust gas collector body 104. This allows the operator to directly use the exhaust gas collector body 104, thus eliminating the cumbersome steps of traditional installation and saving the operator's time and energy.

[0019] Reference Figure 2 and Figure 3The top of the box body 1 is provided with a sliding groove 105, and the bottom of the box cover 102 is fixedly connected with a slider 106. The surface of the slider 106 is slidably connected to the inner cavity of the sliding groove 105. When the box cover 102 is pushed, the stability of the sliding groove 105 ensures that the box cover 102 can slide stably on the top of the box body 1 and avoids the box cover 102 from detaching from the box body 1.

[0020] Reference Figure 1 and Figure 2 The support assembly 3 includes a first bracket 301 fixedly connected to the bottom of the two box covers 102 respectively, and a second bracket 302 fixedly connected to both sides of the box body 1. An inner rod 303 is rotatably connected inside the first bracket 301, and a sleeve rod 304 is rotatably provided inside the second bracket 302. One end of the inner rod 303 is slidably connected to the inner cavity of the sleeve rod 304. When the box cover 102 is pushed, the box cover 102 drives the inner rod 303 to move through the first bracket 301. The inner rod 303 slides in the inner cavity of the sleeve rod 304 and drives the sleeve rod 304 to rotate in the inner cavity of the second bracket 302 to adapt to the angle of movement of the inner rod 303, so as to avoid the inner rod 303 getting stuck in the inner cavity of the sleeve rod 304. Thus, the inner rod 303 can support the box cover 102 and prevent the box cover 102 from tilting up.

[0021] Reference Figure 2 and Figure 4 The sleeve rod 304 is internally fixedly connected to a limiting groove 305, and one end of the inner rod 303 is fixedly connected to a limiting block 306. The surface of the limiting block 306 is slidably connected to the inner cavity of the limiting groove 305. When the inner rod 303 slides in the inner cavity of the sleeve rod 304, the stability of the limiting groove 305 and the limiting block 306 ensures the smoothness of the inner rod 303 sliding in the inner cavity of the sleeve rod 304, and avoids the surface of the inner rod 303 from rubbing against and separating from the inner cavity of the sleeve rod 304.

[0022] Reference Figure 2 and Figure 5 The second support 302 is rotatably connected to a rotating shaft 307. One end of the sleeve rod 304 is fixedly connected to the surface of the rotating shaft 307. One end of the rotating shaft 307 passes through the second support 302 and is rotatably connected to the inner cavity of the second support 302. A ratchet 308 is fixedly sleeved on one end of the rotating shaft 307. Fixing blocks 309 are fixedly connected to both sides of the box 1. A second rotating rod 310 is rotatably connected inside the fixing block 309. A pawl 311 is fixedly sleeved on one end of the second rotating rod 310. The pawl 311 works in conjunction with the ratchet 308. When the movement of the inner rod 303 causes the sleeve rod 304 to rotate in the inner cavity of the second support 302, the sleeve rod 304 drives the rotating shaft 307 to rotate in one direction through the cooperation of the ratchet 308 and the pawl 311, so as to position the box cover 102 and support the placement box 103, so that the placement box 103 remains stable after being raised to the preset height.

[0023] Reference Figure 2 and Figure 5 A torsion spring 312 is provided on the surface of the fixing block 309. One end of the torsion spring 312 is fixedly connected to the surface of the fixing block 309, and the other end of the torsion spring 312 is fixedly connected to the surface of the pawl 311. After the exhaust gas collector body 104 is put back into the inner cavity of the placement box 103, the second rotating rod 310 is twisted, so that the second rotating rod 310 drives the pawl 311 to separate from the ratchet 308, so that the rotating shaft 307 can drive the sleeve rod 304 to rotate, thereby allowing the two box covers 102 to be moved and reset. After the box covers 102 are reset, the twisting of the second rotating rod 310 is released, and the torsion spring 312 drives the pawl 311 to re-engage with the ratchet 308, so that the operator can use it next time.

[0024] Reference Figure 1 and Figure 2 The box 1 is equipped with a tension spring 107 inside. One end of the tension spring 107 is fixedly connected to the inner wall of the box 1, and the other end of the tension spring 107 is fixedly connected to the bottom of the placement box 103. After the second rotating rod 310 is twisted to separate the pawl 311 from the ratchet 308, the tension spring 107 pulls the placement box 103, so that the placement box 103 can drive the transmission rod 203 to rotate, thereby allowing the two box covers 102 to automatically reset, saving the operator's time.

[0025] Working principle: When the exhaust gas collector body 104 needs to be used outdoors, the case 1 is carried out by the shoulder strap 101. After arriving at the destination, the case 1 is placed on a stable surface, and the two side covers 102 are pushed. The cover 102 drives the transmission rod 203 to move, and the transmission rod 203 drives the first rotating rod 204 to rotate. Through the stabilization of the first sector gear 207 and the second sector gear 208, the first rotating rod 204 drives the second connecting rod 206 to rise through the first connecting rod 205, thereby causing the case 103 to move the exhaust gas collector body 104 upward, so that the operator can directly use the exhaust gas collector body 104, avoiding the traditional cumbersome installation steps, thus saving time and energy. When the cover 102 is pushed, the cover 102 drives the inner rod 303 to move. The inner rod 303 slides in the inner cavity of the sleeve rod 304, and drives one end of the sleeve rod 304 to rotate in the inner cavity of the second bracket 302. Through the ratchet 308 and the pawl 31 The stability of the housing 102 is achieved by rotating the shaft 307 unidirectionally via the sleeve rod 304, thereby supporting and positioning the housing cover 102. The housing cover 102 also allows the placement box 103 to resist the downward pressure of the equipment's own weight, ensuring stability after reaching the preset height. After the exhaust gas collector body 104 is in use, the second rotating rod 310 is twisted, causing the pawl 311 to separate from the ratchet 308, thus releasing the positioning of the housing cover 102. At this point, the pull... Spring 107 pulls the placement box 103 down, and the placement box 103 drives the two box covers 102 to move and reset via transmission rod 203. Because the exhaust gas collector body 104 has space inside the placement box 103, the reset of the box covers 102 does not contact the exhaust gas collector body 104. After the box covers 102 are reset, the twisting of the second rotating rod 310 is released, and the torsion spring 312 drives the pawl 311 to re-engage with the ratchet 308 so that the operator can use it next time.
