Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to an exhaust gas collection device for environmental monitoring. Background Technology

[0002] As is well known, waste gas sampling devices for environmental monitoring are specialized equipment used in the field of environmental monitoring to collect various waste gas samples from the atmosphere. They are widely used in industrial plants, chemical industrial parks, urban air monitoring stations, and other scenarios. The device typically consists of a sampling probe, a gas transmission pipeline, a sample storage container, and auxiliary control components. It can perform targeted sampling of different types of waste gas. It generates negative or positive pressure through a power device to introduce the waste gas from the target area into the sample storage container. Then, in conjunction with subsequent detection instruments, the sample is analyzed for composition, providing basic data support for environmental quality assessment and pollution source tracing.

[0003] In existing technologies, the gas inside the collection bottle is not emptied during gas collection, which cannot ensure that there are no other types of gas inside the collection bottle and cannot prevent the sampled gas from being contaminated, which may affect the gas detection results. In addition, the current solution cannot measure the sampling height during sampling, which requires staff to use other tools to detect it separately, thus increasing the workload of staff and reducing convenience. An existing patent (publication number: CN222105173U) discloses an environmental monitoring exhaust gas collection device, belonging to the field of environmental monitoring equipment technology. It includes: a mounting box; a height adjustment mechanism and a power distribution box are installed at the bottom of the inner cavity of the mounting box; the height adjustment mechanism is fixedly connected to a platform through the top of the mounting box; an infrared rangefinder is installed on one side of the platform; the use of a first and second air pump allows the original gas in the gas tank to be extracted before gas collection, thereby improving the accuracy of the environmental monitoring exhaust gas collection device. The combined use of the infrared rangefinder and the height adjustment mechanism facilitates the collection of gas at different heights and makes height measurement convenient, avoiding the current solution's requirement for staff to use other tools to separately measure height, thus increasing the workload of staff and improving the convenience of the environmental monitoring exhaust gas collection device.

[0004] Existing patents offer solutions to the above problems, but the types and concentrations of exhaust gases vary with altitude. Due to the lack of a structure that allows for the accumulation of exhaust gases at different altitudes, it is impossible to collect exhaust gases at different altitudes, reducing the flexibility of exhaust gas collection in the environment.

[0005] Therefore, an exhaust gas collection device for environmental monitoring is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an environmental monitoring waste gas collection device that can solve the problem that existing devices lack a structure that accumulates with height, thus making it impossible to collect waste gas at different heights and reducing the flexibility of waste gas collection in the environment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an environmental monitoring waste gas collection device, comprising a mounting base, an assembly mechanism, and a collection mechanism. The assembly mechanism is located on the top of the mounting base, and the collection mechanism is located inside the assembly mechanism. The assembly mechanism includes an assembly frame, assembly rods, winches, and connecting hooks. The assembly frame is snapped into the top of the mounting base. Four assembly rods are respectively inserted into the two sides of the inner side and the two sides of the inner rear side of the top of the assembly frame. Four winches are respectively fixedly connected to the two sides of the front top and the two sides of the rear top of the assembly frame. The connecting hooks are fixedly connected to the output end of the winches on the side away from the assembly frame.

[0008] Preferably, the collection mechanism includes a drainage component and a collection component, wherein the drainage component is located inside the assembly frame and the collection component is located to the right of the drainage component.

[0009] Preferably, the drainage component includes a support frame, an inner drainage network tube, and an outer drainage network tube. The two support frames are fixedly connected to the two sides of the inner side of the assembly frame, the inner drainage network tube is connected to the right side of the inner side of the support frame, and the outer drainage network tube is snapped into the left side of the inner side of the support frame. The output end of the right side of the outer drainage network tube is connected to the input end of the left side of the inner drainage network tube.

[0010] Preferably, the collection assembly includes a collection guide pipe, a storage gas pipe, and an exhaust gas detector. The collection guide pipe is connected to the right side of the inner drainage network pipe, the storage gas pipe is connected to the output end of the right side of the collection guide pipe, and the exhaust gas detector is connected to the right side of the storage gas pipe.

[0011] Preferably, a positioning ring is fixedly connected to the top of the assembly frame, and the inner side of the positioning ring is in contact with the surface of the assembly insert.

[0012] Preferably, an auxiliary handle is fixedly connected to the shaft of the winch, and the surface of the auxiliary handle is provided with anti-slip texture.

[0013] Preferably, both the surface of the inner drainage network tube and the surface of the outer drainage network tube are fixedly connected to a guide plate, and the guide plate is designed as an arc surface.

[0014] Preferably, a sealing ring is fitted on the side of the collection guide tube near the inner drainage network tube, and the side of the sealing ring near the inner drainage network tube is engaged with the output end of the inner drainage network tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This application sets up an assembly mechanism with a base as a support structure to support the top assembly frame. Through the cooperation of the assembly frame, assembly rods, winch, and connecting hook, the assembly rods can be inserted into the assembly frame, and another set of identical assembly rods can be inserted into the current assembly frame to limit the other set of identical assembly frames until the required height is reached. The winch can drive the connecting hook to move through its own shaft and rope. The connecting hook can be externally connected to the surrounding structure that provides support points. By connecting the connecting hook with the surrounding support points, it forms a positioning structure for the assembly frame with the winch, increasing the structural stability of the assembly frame. 2. This application, by setting up a collection mechanism, allows the diversion component to work in conjunction with the collection component.

The outer diversion network pipe is a larger air guiding channel structure, which can concentrate and guide air into the inner diversion network pipe. The inner diversion network pipe is a smaller air guiding channel structure, which can further concentrate and guide the air concentrated in the outer diversion network pipe into the collection guide pipe. The collected air is collected centrally through the air collection structure composed of the collection guide pipe and the storage air pipe. The collected exhaust gas is detected by the exhaust gas detector. Since the height of the support frame is determined by the height of the assembly frame, exhaust gas can be collected from air at different heights when the assembly frame is in an air environment at different heights.

[0018] 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.

[0019] Please see Figure 1-5 The present invention provides the following technical solution: An environmental monitoring waste gas collection device includes a mounting base 1, an assembly mechanism 2, and a collection mechanism 3. The assembly mechanism 2 is located on the top of the mounting base 1, and the collection mechanism 3 is located inside the assembly mechanism 2. The assembly mechanism 2 includes an assembly frame 21, assembly rods 22, winches 23, and connecting hooks 24. The assembly frame 21 is snapped onto the top of the mounting base 1. Four assembly rods 22 are respectively inserted into the two sides of the inner side of the top of the assembly frame 21 and the two sides of the inner rear side. Four winches 23 are respectively fixedly connected to the two sides of the front top and the two sides of the rear top of the assembly frame 21. The connecting hooks 24 are fixedly connected to the output end of the winch 23 on the side away from the assembly frame 21.

[0020] In this embodiment: by setting up the assembly mechanism 2 and the mounting base 1 as a support structure, the top assembly frame 21 can be supported. Through the cooperation of the assembly frame 21 with the assembly rod 22, the winch 23 and the connecting hook 24, the assembly rod 22 can be inserted into the assembly frame 21, and another set of the same assembly rod 22 can be inserted into the current assembly frame 21 to limit the other set of the same assembly frame 21 until it is installed to the required height. The winch 23 can drive the connecting hook 24 to move through its own shaft and rope. The connecting hook 24 can be externally connected to the surrounding structure that provides support points. By connecting the connecting hook 24 with the surrounding support points, it forms a structure with the winch 23 to position the assembly frame 21, increasing the structural stability of the assembly frame 21.

[0021] Specifically, such as Figure 3 As shown, the collection mechanism 3 includes a drainage component 31 and a collection component 32. The drainage component 31 is located inside the assembly frame 21, and the collection component 32 is located to the right of the drainage component 31.

[0022] Specifically, such as Figure 4As shown, the drainage component 31 includes a support frame 311, an inner drainage network tube 312, and an outer drainage network tube 313. The two support frames 311 are fixedly connected to the two sides inside the assembly frame 21, respectively. The inner drainage network tube 312 is connected to the right side inside the support frame 311, and the outer drainage network tube 313 is snapped into the left side inside the support frame 311. The output end on the right side of the outer drainage network tube 313 is connected to the input end on the left side of the inner drainage network tube 312.

[0023] Specifically, such as Figure 5 As shown, the collection component 32 includes a collection guide pipe 321, a storage pipe 322, and an exhaust gas detector 323. The collection guide pipe 321 is connected to the right side of the inner drainage network pipe 312, the storage pipe 322 is connected to the output end on the right side of the collection guide pipe 321, and the exhaust gas detector 323 is connected to the right side of the storage pipe 322.

[0024] In this embodiment: By setting the collection mechanism 3, the diversion component 31 can be used in conjunction with the collection component 32. The inner diversion network pipe 312 and the outer diversion network pipe 313 are limited by the support frame 311. The outer diversion network pipe 313 is a larger air guiding channel structure, which can concentrate and guide the air into the inner diversion network pipe 312. The inner diversion network pipe 312 is a smaller air guiding channel structure, which can further concentrate and guide the air concentrated by the outer diversion network pipe 313 into the collection guide pipe 321. The collected air is collected in a concentrated manner by the air collection structure composed of the collection guide pipe 321 and the storage air pipe 322. The collected exhaust gas is detected by the exhaust gas detector 323. Since the height of the support frame 311 is determined by the height of the assembly frame 21, exhaust gas in the air at different heights can be collected when the assembly frame 21 is in an air environment at different heights.

[0025] Specifically, such as Figure 2 As shown, a positioning ring 25 is fixedly connected to the top of the assembly frame 21, and the inner side of the positioning ring 25 is in contact with the surface of the assembly rod 22.

[0026] Specifically, such as Figure 2 As shown, an auxiliary handle 26 is fixedly connected to the shaft of the winch 23, and the surface of the auxiliary handle 26 is provided with anti-slip texture.

[0027] In this embodiment: by setting a positioning ring 25 and an auxiliary handle 26, the positioning ring 25 can cooperate with the assembly frame 21. The positioning ring 25 provides auxiliary limiting and guidance at the connection between the assembly frame 21 and the assembly rod 22, which can further increase the stability when the assembly rod 22 is connected to the assembly frame 21. The auxiliary handle 26 can cooperate with the winch 23. By connecting the auxiliary handle 26 to the shaft of the winch 23, it is convenient for the user to rotate the shaft of the winch 23 by holding the handle, so as to further flexibly adjust the effect of the winch 23 in retracting the rope.

[0028] Specifically, such as Figure 4 As shown, both the surface of the inner drainage network pipe 312 and the surface of the outer drainage network pipe 313 are fixedly connected with guide plates 314, and the guide plates 314 are designed as arc surfaces.

[0029] Specifically, such as Figure 5 As shown, a sealing ring 324 is fitted on the side of the collection guide tube 321 near the inner drainage network tube 312, and the side of the sealing ring 324 near the inner drainage network tube 312 is engaged with the output end of the inner drainage network tube 312.

[0030] In this embodiment: by setting the guide plate 314 and the sealing ring 324, the guide plate 314 can cooperate with the inner drainage network pipe 312 and the outer drainage network pipe 313. The guide plate 314, through its own arc surface structure design, can increase the area for air interception and guidance, further increasing the efficiency of air guidance by the inner drainage network pipe 312 and the outer drainage network pipe 313. The sealing ring 324 can cooperate with the collection guide pipe 321. By sealing the connection between the collection guide pipe 321 and the inner drainage network pipe 312 through the sealing ring 324, the sealing performance when the inner drainage network pipe 312 and the collection guide pipe 321 are connected can be further increased.

[0031] Working principle: First, the assembly frame 21 is installed on the mounting base 1, and the assembly frame 21 is fixed by inserting the assembly rod 22 into the assembly frame 21. Then, another set of identical assembly frames 21 is installed on the current assembly frame 21 by inserting the assembly rod 22, until the assembly frame 21 is installed to the required height. Then, the winch 23 on each assembly frame 21 is connected to the fixed structure on the ground by the connecting hook 24 as the support point through its own rope. The rope on the current winch 23 is fixed by the external rope fixing structure. Then... When air at different altitudes passes through the inner drainage pipe 312 and the outer drainage pipe 313, the outer drainage pipe 313 will guide the air to the inner drainage pipe 312. The inner drainage pipe 312 will then further transport the air to the collection guide pipe 321, and finally enter the storage pipe 322 through the collection guide pipe 321. After being fully charged, the exhaust gas detector 323 will detect the exhaust gas in the air through its built-in intelligent control system and exhaust gas detection structure. At this time, the user can connect the exhaust gas detector 323 to an external information display device via a data cable to display and observe the detection information.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
