Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of air particulate matter sampling devices, and more specifically to an air particulate matter sampling device for environmental air pollution control. Background Technology
[0002] Airborne particulate matter is a collection of various solid and liquid particulate substances in the air. Its composition is complex and it is generally divided into primary particulate matter and secondary particulate matter. If the concentration of airborne particulate matter is too high, it will seriously affect the growth of plants and severely damage the human respiratory system. Therefore, it is necessary to use devices to sample airborne particulate matter, test it, and then determine the treatment methods to protect the air.
[0003] For example, the prior art publication number CN220582157U discloses an air particulate matter sampling device for environmental air pollution control. This utility model sets a limiting structure to fix the height of the collection box, thereby realizing the function of easy fixation of the device and improving the applicability of the air particulate matter sampling device for environmental air pollution control in use.
[0004] However, the existing technologies described above still have the following problems in use: When traditional air particulate matter sampling devices are used, the suction force of the sampling device easily causes large debris such as leaves and twigs to adhere to the filter surface, leading to filter blockage. This not only severely disrupts the stability of the sampling flow rate and affects the accuracy of the monitoring data, but also requires manual cleaning by personnel to lower the device before sampling can resume, significantly reducing overall sampling efficiency and operational convenience. Based on this, this utility model provides an environmentally friendly air particulate matter sampling device for atmospheric treatment with anti-clogging function. Utility Model Content
[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides an air particulate matter sampling device for environmental air pollution control. By assembling an elbow pipe on the sampling tube, it can both utilize the internal mesh plate to block large-volume debris, preventing it from clogging the subsequent filter plate and stabilizing the sampling volume, and use an automatically rotating cover plate to push away debris attached to the bottom of the mesh plate. Combined with the downward-facing air inlet design of the elbow pipe, the debris falls naturally under gravity, significantly reducing the probability of mesh plate clogging, thereby effectively improving the stability of sampling and solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an air particulate matter sampling device for environmental air pollution control, comprising a sampling cylinder, a bent pipe fixedly provided at one end of the sampling cylinder, a filter assembly provided inside the bent pipe, the filter assembly including a mesh plate installed inside the bent pipe, a connecting rod fixedly provided at the top of the mesh plate, a filter plate fixedly provided at the top of the connecting rod, a first motor fixedly embedded on one side of the bent pipe, a cover plate fixedly provided at the bottom end of the output shaft of the first motor, the cover plate being located at the bottom of the bent pipe, a fixing seat sleeved on the outer wall of the sampling cylinder, a second motor fixedly provided at the bottom of the fixing seat, and a lifting assembly provided at the bottom of the second motor.
[0007] In a preferred embodiment, a support plate is fixedly provided at the end of the sampling tube away from the elbow pipe, and a vacuum pump communicating with the inside of the sampling tube is fixedly provided on the top of the support plate. A protective cover for protecting the vacuum pump is installed on the top of the support plate. Ventilation holes are provided on both the front and rear sides of the protective cover. The protective cover covers the outside of the vacuum pump, thereby providing protection.
[0008] In a preferred embodiment, the lifting assembly includes a base, a hollow column fixedly mounted on the top of the base, an electric push rod fixedly mounted inside the hollow column, a cylinder fixedly mounted on the top of the electric push rod, and a second motor fixed inside the cylinder. The height of the sampling cylinder is automatically adjusted using the electric push rod, making it very convenient to use.
[0009] In a preferred embodiment, the base is fixed with a plurality of anchor rods arranged in a circular array at its bottom. The design of multiple anchor rods can improve the stability of the base placement.
[0010] In a preferred embodiment, handles are fixedly provided on both sides of the outer wall of the hollow column, and the surface of the handles is processed with anti-slip texture to facilitate the handling of the device by the staff.
[0011] In a preferred embodiment, a limiting ring is fixedly provided inside the elbow pipe. The limiting ring is located on the top of the filter plate. When reinstalling the filter plate and the screen, the operator only needs to push them into the elbow pipe until the top of the filter plate contacts the bottom of the limiting ring, thereby improving the installation efficiency.
[0012] In a preferred embodiment, a canopy is fixedly provided on the top of the mounting base, and solar panels are fixedly embedded on both the front and rear sides of the top of the canopy. The solar panels absorb solar energy and convert it into electrical energy, thereby saving energy.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. This utility model, by assembling an elbow pipe on the sampling tube, can, on the one hand, use the mesh plate inside the pipe to block large-volume debris, preventing it from clogging the subsequent filter plate and stabilizing the sampling volume; on the other hand, the cover plate can be rotated by the first motor, which pushes away the debris attached to the bottom of the mesh plate. Combined with the downward air inlet design of the elbow pipe, the debris falls naturally with gravity, significantly reducing the probability of mesh plate clogging, thereby effectively improving the stability of sampling.
[0015] 2. The sampling tube is rotated by driving the fixed base with the second motor and adjusting the orientation of the elbow tube, which can flexibly change the sampling range, thereby improving the uniformity of sampling to a certain extent and ensuring the representativeness of the sampling data.

[0024] 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.
[0025] Refer to the instruction manual appendix Figures 1-5 This utility model provides an air particulate matter sampling device for environmental air pollution control, including a sampling cylinder 1. One end of the sampling cylinder 1 is fixedly provided with a bend pipe 2. The bend pipe 2 is provided with a filter assembly 3. The filter assembly 3 includes a mesh plate 31 installed inside the bend pipe 2. A connecting rod 32 is fixedly provided on the top of the mesh plate 31. A filter plate 33 is fixedly provided on the top of the connecting rod 32. A first motor 4 is fixedly embedded on one side of the bend pipe 2. A cover plate 5 is fixedly provided at the bottom of the output shaft of the first motor 4. The cover plate 5 is located at the bottom of the bend pipe 2. A fixing seat 6 is sleeved on the outer wall of the sampling cylinder 1. A second motor 7 is fixedly provided at the bottom of the fixing seat 6.
[0026] A support plate 9 is fixedly provided at the end of the sampling tube 1 away from the elbow pipe 2. A vacuum pump 10 communicating with the inside of the sampling tube 1 is fixedly provided on the top of the support plate 9. A protective cover 11 for protecting the vacuum pump 10 is installed on the top of the support plate 9. Ventilation holes 12 are provided on both the front and rear sides of the protective cover 11.
[0027] In actual operation, the staff first needs to move the entire device to the designated sampling position, then start the first motor 4 to drive the cover plate 5 to move away from the bottom of the elbow pipe 2. Next, the vacuum pump 10 is turned on to draw in outside air to carry out air particulate matter sampling. The elbow pipe 2 is equipped with a mesh plate 31, which can block large debris such as leaves and plant branches, preventing such debris from clogging the subsequent filter plate 33, thus avoiding affecting the sampling volume. The air that has been initially filtered by the mesh plate 31 will be further filtered by the filter plate 33, ultimately leaving the air particulate matter inside the sampling tube 1, which facilitates subsequent testing. At the same time, during the sampling process, the first motor 4 can drive the cover plate 5 to rotate, using the cover plate 5 to push away the large debris attached to the bottom of the mesh plate 31. In addition, thanks to the special structural design of the elbow pipe 2, its air inlet faces downward, allowing the pushed-away large debris to fall naturally under its own gravity, which can reduce the risk of the mesh plate 31 being blocked to a certain extent. In addition, the second motor 7 can be started to drive the fixed base 6 to rotate the sampling tube 1. By adjusting the orientation of the elbow tube 2, the sampling range can be flexibly changed, thereby improving the uniformity of sampling to a certain extent and ensuring the representativeness of the sampling data.
[0028] A limiting ring 15 is fixed inside the elbow pipe 2. The limiting ring 15 is located on the top of the filter plate 33. With the design of the limiting ring 15, when reinstalling the filter plate 33 and the mesh plate 31, the operator only needs to push the two into the elbow pipe 2 until the top of the filter plate 33 contacts the bottom of the limiting ring 15, thereby improving the installation efficiency.
[0029] Refer to the instruction manual appendix Figure 1 and Figure 3The second motor 7 has a lifting assembly 8 at its bottom. The lifting assembly 8 includes a base 81. A hollow column 82 is fixedly provided on the top of the base 81. An electric push rod 83 is fixedly provided inside the hollow column 82. A cylinder 84 is fixedly provided on the top of the electric push rod 83. The second motor 7 is fixed inside the cylinder 84.
[0030] The base 81 is fixed with a plurality of anchor rods 13 arranged in a ring array at its bottom. The hollow column 82 is fixed with handles 14 on both sides of its outer wall. The surface of the handles 14 is processed with anti-slip texture to facilitate the handling of the device by the staff. The design of multiple anchor rods 13 can improve the stability of the base 81.
[0031] And, as Figure 1 As shown, a canopy 16 is also fixedly installed on the top of the fixed base 6. Solar panels 17 are fixedly embedded on both the front and rear sides of the top of the canopy 16. The solar panels 17 absorb solar energy and convert it into electrical energy, thereby saving energy.
[0032] 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.
