Abstract
Description
Technical Field
[0001] This utility model belongs to the field of environmental protection technology, specifically relating to a dust-blocking net for dust control. Background Technology
[0002] Dust control refers to comprehensive prevention and control measures taken to prevent loose particulate matter (such as construction dust, road dust, industrial raw materials, etc.) from spreading into the atmosphere due to natural forces or human activities. Its core objective is to reduce the concentration of inhalable particulate matter (PM10, PM2.5) in the air. The targets of control include dust generated by construction sites, demolition projects, municipal construction, etc., dust spilled by vehicles, dust spread by the wind from roads, materials such as coal, sand, gravel, and slag piled up in the open, unpaved land, and high-rise green belts, etc.
[0003] Using dust-blocking nets is one method of dust control.
[0004] When selecting dust control nets for dust pollution control, air permeability is one of the key performance indicators. Therefore, dust control nets need to be replaced after prolonged use. This is because clogging of the dust control net can cause the pores to be filled with dust, obstructing airflow and allowing airflow to escape from the edges or damaged areas of the net, carrying unfiltered dust and spreading it. This contradicts the design principle of dust control nets, which slows down and settles particles through airflow. However, to ensure the wind resistance of the dust control nets, each net is bound with a large number of ropes on all four sides, making installation difficult and disassembly troublesome. Moreover, in areas prone to rockfalls, ordinary dust control nets cannot withstand the impact well and are easily damaged. Therefore, further structural optimization needs to be considered. Utility Model Content
[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a dust-blocking net for dust control.
[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0007] A dust-control net includes a base frame with a through slot. Two fixed rods are placed in the through slot. The bottom of each fixed rod has a stake tip. A pressure plate is fixedly installed on each fixed rod. The fixed rod has several rope hooks. A sliding cylinder is sleeved on the fixed rod. A locking screw is threaded onto the sliding cylinder. The end of the locking screw contacts the fixed rod. A connecting plate is integrally connected to the bottom of the sliding cylinder. A top strip is installed on the lower side of the connecting plate.
[0008] The base frame is integrally connected with two first T-shaped blocks, and the top strip is provided with two first T-shaped grooves. The base frame and the top strip are equipped with front wire mesh and rear wire mesh through the first T-shaped blocks and the first T-shaped grooves. The front wire mesh and the rear wire mesh have the same structure.
[0009] Both the front wire mesh and the rear wire mesh are provided with a second T-shaped groove that matches the specifications of the first T-shaped block. Both the front wire mesh and the rear wire mesh are provided with a second T-shaped block that matches the specifications of the first T-shaped groove. Both the front wire mesh and the rear wire mesh are provided with slot openings.
[0010] The front wire mesh and the rear wire mesh are fitted with dust-blocking nets through the slot openings. Inserts are installed at both ends of the dust-blocking nets, and ropes are connected to both ends of the inserts. The ends of the ropes are fixed to the rope hooks.
[0011] Furthermore, the front wire mesh and the rear wire mesh can be spliced together by the second T-slot and the second T-block. This design allows for adaptive adjustment of the protection range through splicing and installation, ensuring a suitable range.
[0012] Furthermore, both the front and rear wire meshes are made of metal wire mesh, which provides good impact resistance.
[0013] Furthermore, the top bar is installed on the connecting plate by screws. With this design, even if the distance between the two fixing rods is changed, the connection between the connecting plate and the top bar can still be completed by screws.
[0014] Furthermore, the insert is a rigid insert, a design that allows for sufficient tensile strength to the dust filter while it is pulled out of the slot.
[0015] The beneficial effects of using this utility model are as follows:
[0016] With the structural design of this utility model, the dust blocking net is installed in the middle area between the front wire mesh and the rear wire mesh, so the front wire mesh and the rear wire mesh achieve impact protection for the dust blocking net and ensure the service life of the dust blocking net.
[0017] With the structural design of this utility model, only four ropes need to be tied during installation, ensuring installation efficiency;
[0018] The structural design of this utility model allows the entire dustproof net to be removed by taking out the insert strip, which is convenient for replacement and maintenance. Attached Figure Description

[0027] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0028] like Figures 1-5 As shown, a dust-blocking net for dust control according to this utility model includes a base frame 1. The base frame 1 is provided with a through slot 2. Two fixed rods 3 are placed in the through slot 2. The bottom of the fixed rods 3 is provided with a pile tip 4. A pressure plate 5 is fixedly installed on the fixed rods 3. Several rope hooks 6 are provided on the fixed rods 3. A sliding cylinder 7 is sleeved on the fixed rods 3. A locking screw 8 is threadedly connected to the sliding cylinder 7. The end of the locking screw 8 contacts the fixed rod 3. A connecting plate 9 is integrally connected to the bottom of the sliding cylinder 7. A top strip 10 is installed on the lower side of the connecting plate 9.
[0029] The base frame 1 is integrally connected with two first T-shaped blocks 11, and the top strip 10 is provided with two first T-shaped grooves 12. The base frame 1 and the top strip 10 are equipped with a front wire mesh 13 and a rear wire mesh 14 through the first T-shaped blocks 11 and the first T-shaped grooves 12. The front wire mesh 13 and the rear wire mesh 14 have the same structure.
[0030] Both the front wire mesh 13 and the rear wire mesh 14 are provided with a second T-shaped groove 15 that matches the specifications of the first T-shaped block 11, both the front wire mesh 13 and the rear wire mesh 14 are provided with a second T-shaped block 16 that matches the specifications of the first T-shaped groove 12, and both the front wire mesh 13 and the rear wire mesh 14 are provided with slot openings 17.
[0031] Dust-blocking mesh 18 is installed on the front wire mesh 13 and the rear wire mesh 14 through the slot 17. Insert strips 19 are installed at both the upper and lower ends of the dust-blocking mesh 18. Wire ropes 20 are connected to both ends of the insert strips 19, and the ends of the wire ropes 20 are fixed to the rope hooks 6.
[0032] In this implementation case, when using a dust control net, the base frame 1 is placed directly in the installation area. Then, the fixing rod 3 is inserted into the ground through the through slot 2 via the pile tip 4. The pressure plate 5 can be used to tap the pile tip 4 into the soil until the pressure plate 5 presses down on the base frame 1, thus fixing the position of the base frame 1. Then, through the cooperation of the first T-block 11 and the second T-slot 15, the front wire mesh 13 and the rear wire mesh 14 are installed on the base frame 1 by inserting them from the side. Depending on the needs, the corresponding number of front wire mesh 13 and rear wire mesh 14 are selected and spliced until the protective area is reached. It should be noted that the corresponding dust control net 18 also needs to be prepared with the corresponding specifications and sizes. After the front wire mesh 13 and the rear wire mesh 14 are spliced, the top strip 10 is inserted from the side and installed on the front wire mesh 13 and the rear wire mesh 14 through the cooperation of the first T-slot 12 and the second T-block 16. The top of the front and rear wire mesh 13 and the top of the rear wire mesh 14 are then moved to the upper side of the top strip 10. The top strip 10 is fixed by the connecting plate 9. At this time, the sliding cylinder 7 can be fixed by the locking screw 8, or it can be left unfixed depending on the situation. The front wire mesh 13 and the rear wire mesh 14 provide support for the top strip 10. In this way, the front wire mesh 13 and the rear wire mesh 14 are fixed in the front and rear directions. It should be noted that the left and right sides of the front wire mesh 13 and the rear wire mesh 14 are not fixed, so as to facilitate the removal and replacement of a single front wire mesh 13 or rear wire mesh 14 and ensure the effect of use. The dustproof net 18 with insert strips 19 installed at both ends is inserted between the front wire mesh 13 and the rear wire mesh 14 by inserting the insert strips 19 into the slot 17. The ropes 20 at both ends of the insert strips 19 can be dragged to assist the insertion of the insert strips 19. Then the ropes 20 are fixed on the rope hooks 6 to complete the overall installation.
[0033] During use, the front wire mesh 13 and the rear wire mesh 14 provide impact protection for the dustproof mesh 18.
[0034] After a period of use, the dust filter 18 is removed from the front wire mesh 13 and the rear wire mesh 14 and a new dust filter 18 is inserted to complete the replacement, which is simple, convenient and quick.
[0035] Preferably, the front wire mesh 13 and the rear wire mesh 14 can be spliced together by the second T-slot 15 and the second T-block 16. This design allows for adaptive adjustment of the protection range through splicing and installation, ensuring the fit range. In practice, the number and splicing method of the front wire mesh 13 and the rear wire mesh 14 can also be considered according to the specific situation.
[0036] It is preferable that both the front wire mesh 13 and the rear wire mesh 14 are made of metal wire mesh. This design provides good impact resistance. In fact, the material selection for the front wire mesh 13 and the rear wire mesh 14 can also be considered according to specific circumstances.
[0037] Preferably, the top bar 10 is installed on the connecting plate 9 by screws. With this design, even if the distance between the two fixing rods 3 is changed, the connection between the connecting plate 9 and the top bar 10 can still be completed by screws. In fact, the connection structure between the top bar 10 and the connecting plate 9 can also be considered according to the specific situation.
[0038] The preferred insert 19 is a rigid insert. This design facilitates the pulling out of the slot 17 while providing sufficient tensile strength to the dust filter 18. In fact, the material of the insert 19 can also be selected according to specific circumstances.
[0039] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
