A variable aperture dustproof net

Abstract

This application discloses a variable aperture dustproof net used in the field of dustproof netting. This dustproof net achieves dustproofing through the relative movement of a dynamic dustproof plate and a static dustproof plate. The movement of the dynamic dustproof plate causes the aperture adjustment cone to move back and forth within a second dustproof hole, thereby changing the aperture of the second dustproof hole and effectively improving the flexibility of the dustproof net. Simultaneously, the staggered arrangement of the first and second dustproof holes further enhances the dustproofing effect. Magnetic attraction causes the sliding block to move along with a magnetic marker, allowing the magnetic marker to move on a contact pad. This allows external personnel to observe the position of the magnetic marker through the light-transmitting plate and the contact pad, thus transmitting a signal to the outside world to adjust the aperture size. This facilitates adjustment of the relative positions of the dynamic and static dustproof plates, achieving efficient dustproofing while also changing the size of the dustproof aperture, thereby improving the environmental adaptability of the dustproof net.

Description

Technical Field

[0001] This application relates to the field of dust control nets, and in particular to a variable aperture dust control net. Background Technology

[0002] Dust control netting is mainly used for windbreak and dust suppression in coal storage yards of coal mines, coking plants, power plants, and other enterprises; coal storage yards and various material yards in ports and docks; dust suppression in various open-air material yards of steel, building materials, cement, and other enterprises; wind protection for crops and dust prevention in sandy weather and other harsh environments; coal storage yards at railway and highway coal transfer stations, construction sites, road dust, and both sides of highways. Single-layer windbreak and dust suppression walls can achieve a dust suppression effect of 65-85%, while double-layer windbreak and dust suppression walls can achieve an effect of over 95%.

[0003] Dust control nets are flexible and versatile in use, but the existing dust control nets have fixed mesh sizes. Different mesh sizes are required for different dust control requirements, which means that several sizes of dust control nets need to be prepared. This not only increases the cost, but also makes it troublesome to replace the dust control nets back and forth.

[0004] Therefore, we use this dustproof net to solve the problem that existing dustproof nets cannot change the aperture. Summary of the Invention

[0005] The purpose of this application is to improve the existing dustproof nets by providing a variable aperture dustproof net. Dust prevention is achieved through the relative movement of a dynamic dustproof plate and a static dustproof plate. The dynamic dustproof plate moves due to the engagement of a screw and a slide, causing the aperture adjustment cone to move back and forth within the second dustproof hole, thus changing the aperture of the second dustproof hole. This effectively improves the flexibility of the dustproof net. Furthermore, the staggered arrangement of the first and second dustproof holes further enhances the dustproof effect. Magnetic attraction causes the slide to move along with a magnetic marker, allowing the magnetic marker to move on a mating pad. The interaction between the magnetic marker and the mating pad allows external personnel to observe the position of the magnetic marker through the light-transmitting plate and the mating pad, thus transmitting a signal to the outside world to adjust the aperture size and facilitating the adjustment of the relative positions of the dynamic and static dustproof plates.

[0006] While achieving efficient dust prevention, it can also change the size of the dust prevention pores, thereby improving the environmental adaptability of the dust prevention net.

[0007] Furthermore, the diameter of dustproof hole one is smaller than that of dustproof hole two, and dustproof hole one and dustproof hole two are staggered. Dust first passes through dustproof hole two and is then dispersed to dustproof hole one, which can effectively improve the dustproof effect.

[0008] Furthermore, the diameter of the aperture adjusting cone is equal to the inner diameter of the second dustproof hole, and the aperture adjusting cone is made of wear-resistant plastic. The aperture adjusting cone moves in the second dustproof hole, thereby changing the diameter of the dustproof hole. Due to the friction between the aperture adjusting cone and the inner diameter of the second dustproof hole when changing the diameter, the aperture adjusting cone must be made of wear-resistant plastic.

[0009] Furthermore, a positioning sleeve is fixedly fitted on the outer wall of the aperture adjusting cone. The positioning sleeve is made of rubber and is used to prevent the aperture adjusting cone from moving further in the dustproof hole 2, thus playing a positioning role when adjusting the aperture.

[0010] Optionally, the mounting adjustment plate has a marking cavity on one side of the mounting cavity's inner wall, and a slide rod is fixedly connected to the inner wall of the marking cavity. A magnetic marker that magnetically attracts the slide block is slidably connected to the slide rod. A mating marking pad that abuts against the magnetic marker is fixedly connected to the inner wall of the marking cavity away from the slide block. A light-transmitting plate is fixedly embedded on the inner wall of the mounting adjustment plate between the mating marking pad and the outer surface. When the slide block moves, the magnetic marker moves along with it through magnetic attraction. The position of the magnetic marker on the mating marking pad can be seen through the light-transmitting plate. This allows external personnel to intuitively know the moving position of the dynamic dustproof plate during adjustment, thus facilitating the change of the aperture.

[0011] Furthermore, the adhesive marking pad includes two transparent films, with light-blocking liquid filling the space between them. Due to the contact between the magnetic marker and the adhesive marking pad, the magnetic marker can displace the light-blocking liquid and be reflected on the outermost transparent film. In this way, outsiders can see the position of the magnetic marker through the light-transmitting plate, thereby indirectly knowing the position of the aperture adjustment cone in the second dustproof hole, and thus adjusting the aperture.

[0012] Furthermore, the magnetic marker includes a slider that is slidably connected to the slide bar, and a rounded cone is fixedly connected to one end of the slider that abuts against the abutting marking pad. The outer surface of the rounded cone is coated with a fluorescent coating. The rounded cone rests against the outermost transparent film, and the fluorescent coating allows external personnel to see through the light-transmitting plate to the position of the magnetic marker.

[0013] Furthermore, the slide includes a square base, and the side wall of the square base is provided with a screw hole that engages with the screw. A magnetic block that magnetically attracts the magnetic marker is fixedly connected to the side wall of the square base. The engagement of the screw and the screw hole causes the slide to move in parallel, thereby adjusting the dustproof hole diameter. The magnetic block drives the magnetic marker to move by relying on the magnetic attraction force with the magnetic marker.

[0014] Furthermore, a dustproof cylinder is installed between the dynamic dustproof plate and the static dustproof plate. The dustproof cylinder is connected to the dynamic dustproof plate and the static dustproof plate by magnetic attraction. The dustproof cylinder is placed directly opposite the first dustproof hole. Dust enters from the second dustproof hole and is dispersed into the first dustproof hole, playing a preliminary dustproof role. The dustproof cylinder further protects the dust that enters the first dustproof hole, thereby effectively improving the dustproof effect.

[0015] Furthermore, the dustproof cylinder includes two magnetic suction rings, and a flexible dustproof net is fixedly connected between the two magnetic suction rings. When the dustproof cylinder is installed, the two magnetic suction rings are magnetically attracted to the dynamic dustproof plate and the static dustproof plate respectively, thereby achieving connection, while the flexible dustproof net plays a further role in dust prevention.

[0016] Compared to existing technologies, the advantages of this application are:

[0017] (1) This solution achieves dust prevention through the relative movement of dynamic and static dust prevention plates. The dynamic dust prevention plate moves by the meshing of the screw and the slide. The movement of the dynamic dust prevention plate causes the aperture adjustment cone to move back and forth in the second dust prevention hole, thereby changing the aperture of the second dust prevention hole and effectively improving the flexibility of the dust prevention net. At the same time, the staggered setting of the first and second dust prevention holes is used to effectively improve the dust prevention effect. The magnetic attraction causes the slide to move the magnetic marker together, thereby allowing the magnetic marker to move on the abutment marking pad. Due to the abutment between the magnetic marker and the abutment marking pad, the position of the magnetic marker can be observed by outsiders through the light-transmitting plate and the abutment marking pad, thereby transmitting the aperture adjustment signal to the outside world. This facilitates the adjustment of the relative position of the dynamic and static dust prevention plates, achieving efficient dust prevention while also changing the size of the dust prevention aperture, thereby improving the environmental adaptability of the dust prevention net.

[0018] (2) The diameter of the first dustproof hole is smaller than that of the second dustproof hole, and the first and second dustproof holes are staggered. Dust first passes through the second dustproof hole and then is dispersed to the first dustproof hole, which can effectively improve the dustproof effect.

[0019] (3) The diameter of the aperture adjustment cone is equal to the inner diameter of the dustproof hole 2, and the aperture adjustment cone is made of wear-resistant plastic material. The aperture adjustment cone moves in the dustproof hole 2 to change the diameter of the dustproof hole. Due to the friction between the aperture adjustment cone and the inner diameter of the dustproof hole 2 when changing the diameter, the aperture adjustment cone must be made of wear-resistant plastic material.

[0020] (4) A positioning sleeve is also fixedly fitted on the outer wall of the aperture adjustment cone. The positioning sleeve is made of rubber. The positioning sleeve is to prevent the aperture adjustment cone from moving further in the dustproof hole 2 and plays a positioning role when adjusting the aperture.

[0021] (5) The inner wall of the mounting cavity of the installation adjustment plate is also provided with a marking cavity, and the inner wall of the marking cavity is fixedly connected with a slide rod. A magnetic marking element that magnetically attracts the slide block is slidably connected on the slide rod. The inner wall of the marking cavity away from the slide block is fixedly connected with a mating marking pad that abuts against the magnetic marking element. A light-transmitting plate is fixedly embedded on the inner wall of the installation adjustment plate between the mating marking pad and the outer surface. When the slide block moves, the magnetic marking element moves together through the magnetic attraction. The position of the magnetic marking element on the mating marking pad can be seen through the light-transmitting plate. In this way, when adjusting, outsiders can intuitively know the moving position of the dynamic dustproof plate, which makes it convenient to change the aperture.

[0022] (6) The adhesive marking pad includes two transparent films, and the space between the two transparent films is filled with light-blocking liquid. Due to the abutment between the magnetic marking element and the adhesive marking pad, the magnetic marking element can displace the light-blocking liquid and be reflected on the outermost transparent film. In this way, outsiders can know the position of the magnetic marking element through the light-transmitting plate, thereby indirectly knowing the position of the aperture adjustment cone in the dustproof hole 2, so as to adjust the aperture.

[0023] (7) The magnetic marker includes a slider that is slidably connected to the slider, and a round cone is fixedly connected to one end of the slider that abuts against the abutting marker pad. The outer surface of the round cone is coated with a fluorescent coating. The round cone rests against the outermost transparent film. The fluorescent coating allows outside personnel to pass through the light-transmitting plate to the position of the magnetic marker.

[0024] (8) The slide includes a square seat, and the side wall of the square seat is provided with a screw hole that meshes with the screw. A magnetic block that magnetically attracts the magnetic marker is fixedly connected to the side wall of the square seat. The meshing of the screw and the screw hole causes the slide to move in parallel, thereby adjusting the dustproof hole diameter. The magnetic block drives the magnetic marker to move by relying on the magnetic attraction force with the magnetic marker.

[0025] (9) A dustproof cylinder is also provided between the dynamic dustproof plate and the static dustproof plate. The dustproof cylinder is connected to the dynamic dustproof plate and the static dustproof plate by magnetic attraction. The dustproof cylinder is placed facing the first dustproof hole. Dust enters from the second dustproof hole and is dispersed into the first dustproof hole, playing a preliminary dustproof role. The dustproof cylinder further protects the dust that enters the first dustproof hole, thereby effectively improving the dustproof effect.

[0026] (10) The dustproof cylinder includes two magnetic suction rings, and a flexible dustproof net is fixedly connected between the two magnetic suction rings. When the dustproof cylinder is installed, the two magnetic suction rings are magnetically attracted to the dynamic dustproof plate and the static dustproof plate respectively, thereby achieving connection, while the flexible dustproof net plays a further role in dust prevention.

[0040] The embodiments will be described clearly and completely with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0041] Example 1:

[0042] A variable aperture dustproof screen, please refer to Figure 1 , 2 3, 8, 9 and Figure 10The device includes two mounting adjustment plates 1, a dynamic dustproof plate 2 slidably connected between the two mounting adjustment plates 1, and a static dustproof plate 3 fixedly connected between the two mounting adjustment plates 1. A dustproof cylinder 12 is also provided between the dynamic dustproof plate 2 and the static dustproof plate 3, and the dustproof cylinder 12 is connected to the dynamic dustproof plate 2 and the static dustproof plate 3 by magnetic attraction. The dustproof cylinder 12 is placed facing the first dustproof hole 201. Dust enters from the second dustproof hole 301 and is dispersed into the first dustproof hole 201, playing a preliminary dustproof role. The dustproof cylinder 12 further protects the dust entering the first dustproof hole 201, thereby effectively improving the dustproof effect. The dustproof cylinder 12 includes two magnetic suction rings 1201. A flexible dustproof net 1202 is fixedly connected between 1201. When the dustproof cylinder 12 is installed, the two magnetic suction rings 1201 are magnetically attracted to the dynamic dustproof plate 2 and the static dustproof plate 3 respectively, thereby achieving connection. The flexible dustproof net 1202 plays a further role in dust prevention. The side wall of the dynamic dustproof plate 2 has multiple dustproof holes 1 201 distributed at equal intervals. The side wall of the static dustproof plate 3 also has multiple dustproof holes 2 301 distributed at equal intervals. The diameter of the dustproof hole 1 201 is smaller than that of the dustproof hole 2 301. The dustproof hole 1 201 and the dustproof hole 2 301 are staggered. Dust first passes through the dustproof hole 2 301 and is then dispersed to the dustproof hole 1 201, which can effectively improve the dust prevention effect.

[0043] Please see Figure 4 , 5 and Figure 11Furthermore, multiple aperture adjustment cones 4 are fixedly connected to the side wall of the dynamic dustproof plate 2 opposite to the dustproof hole 301. The diameter of the aperture adjustment cone 4 is equal to the inner diameter of the dustproof hole 301, and the aperture adjustment cone 4 is made of wear-resistant plastic. The aperture adjustment cone 4 moves in the dustproof hole 301, thereby changing the diameter of the dustproof hole. Due to the friction between the aperture adjustment cone 4 and the inner diameter of the dustproof hole 301 when changing the diameter, the aperture adjustment cone 4 must be made of wear-resistant plastic. A positioning sleeve 401 is also fixedly fitted on the outer wall of the aperture adjustment cone 4, and the positioning sleeve 401 is made of rubber. The positioning sleeve 401 is used to prevent the aperture adjustment cone 4 from moving further in the dustproof hole 301 and plays a positioning role when adjusting the diameter. The inner wall of the mounting adjustment plate 1 has an installation cavity 101, and the side of the installation cavity 101... The wall has an open slide groove 102. Both ends of the dynamic dustproof plate 2 pass through the open slide groove 102 and extend into the mounting cavity 101. A servo motor 5 is installed on one inner wall of the mounting cavity 101, and a screw 6 connected to the output end of the servo motor 5 is rotatably connected to the inner wall of the mounting cavity 101. A slide 7 is fixedly connected to the side wall of the dynamic dustproof plate 2, and the slide 7 meshes with the screw 6. The slide 7 includes a square seat 701, and a screw hole 702 that meshes with the screw 6 is opened on the side wall of the square seat 701. A magnetic block 703 that magnetically attracts the magnetic marker 9 is fixedly connected to the side wall of the square seat 701. The meshing of the screw 6 and the screw hole 702 causes the slide 7 to move in parallel, thereby adjusting the dustproof hole diameter. The magnetic block 703 drives the magnetic marker 9 to move by relying on the magnetic attraction force with the magnetic marker 9.

[0044] Example 2:

[0045] Based on Example 1, please refer to Figure 5 , 7 The mounting adjustment plate 1 is located on one side of the inner wall of the mounting cavity 101 and a marking cavity 103 is provided. A slide rod 8 is fixedly connected to the inner wall of the marking cavity 103. A magnetic marker 9 that magnetically attracts the slide seat 7 is slidably connected to the slide rod 8. A mating marking pad 10 that abuts against the magnetic marker 9 is fixedly connected to the inner wall of the marking cavity 103 away from the slide seat 7. A light-transmitting plate 11 is fixedly embedded on the inner wall of the mounting adjustment plate 1 between the mating marking pad 10 and the outer surface. When the slide seat 7 moves, the magnetic marker 9 moves together through magnetic attraction. The position of the magnetic marker 9 on the mating marking pad 10 can be seen through the light-transmitting plate 11. In this way, when adjusting, outsiders can intuitively know the moving position of the dynamic dustproof plate 2, which makes it convenient to change the aperture.

[0046] Please see Figure 6The adhesive marking pad 10 includes two transparent films 1001, and the space between the two transparent films 1001 is filled with light-blocking liquid 1002. Since the magnetic marker 9 abuts against the adhesive marking pad 10, the magnetic marker 9 can displace the light-blocking liquid 1002 and be reflected on the outermost transparent film 1001. In this way, outsiders can know the position of the magnetic marker 9 through the light-transmitting plate 11, thereby indirectly knowing the position of the aperture adjustment cone 4 in the dustproof hole 301, and thus adjusting the aperture. The magnetic marker 9 includes a slider that is slidably connected to the slider 8, and a round-headed cone is fixedly connected to the end of the slider that abuts against the adhesive marking pad 10. The outer surface of the round-headed cone is coated with a fluorescent coating. The round-headed cone abuts against the outermost transparent film 1001. The fluorescent coating allows outsiders to see through the light-transmitting plate 11 to the position of the magnetic marker 9.
