Description

Technical Field

[0001] The utility model relates to a dust-proof net, in particular to a dust-proof net for water conservancy construction, belonging to the technical field of dust-proof nets. Background Technique

[0002] The dust-proof net, also known as the "wind-proof and dust-suppressing net" and "wind-proof wall", is an environmental protection project for controlling the dust pollution of open-air material yards. The purpose of the dust-proof net is to intercept the dust in the air, prevent the dust from dispersing from the generation position to other areas, and avoid causing air pollution in other areas. During the process of water conservancy construction, large-area land operations are usually accompanied, and a large amount of dust will be generated during this period. Therefore, a dust-proof net needs to be installed during the construction process.

[0003] The common dust-proof nets for building construction are usually rope-net dust-proof nets, which are flexible structures. Due to their ability to be rolled up and wound, easy to carry, and low cost, they are mostly used in building construction sites. However, the current rope-net dust-proof nets still have certain drawbacks in application. When they are unfolded for use, it is not easy to achieve fixation and restraint. They are usually tied in cooperation with scaffolding steel pipes or directly covered on the materials and then fixed by fixing parts. It is not convenient to achieve enclosure for dust prevention. At the same time, the dust-proof net is not convenient to roll up after use, and the reusability is relatively poor.

[0004] Therefore, a dust-proof net for water conservancy construction is proposed here. Content of the Utility Model

[0005] The utility model provides a dust-proof net for water conservancy construction to solve the problems that the common construction dust-proof nets in the prior art have poor fixation and restraint ability and are not convenient to achieve enclosure for dust prevention, and at the same time solve the problem that the common construction dust-proof nets have relatively poor reusability.

[0006] The utility model is realized through the following technical solutions: A dust-proof net for water conservancy construction includes an upper support and a lower support. A clamping device is arranged on the side surfaces of the upper support and the lower support close to each other. A rotating rod is arranged between the upper support and the lower support. Disks are fixed at both ends of the rotating rod. A plurality of side plates arranged in a circular shape are fixed on the outer surface of the rotating rod. An arc-shaped outer plate is fixed on the outer side surface of the side plate. A dust-proof net body is arranged outside the rotating rod. Arc-shaped clamping plates are fixed at both ends of the dust-proof net body.

[0007] The size of the arc-shaped clamping plate is larger than the distance between the two arc-shaped outer plates. A bottom plate is fixed between two adjacent side plates. The bottom end of the arc-shaped clamping plate is in contact with the bottom plate. The arc-shaped clamping plate is placed between the two arc-shaped outer plates through the top end of the arc-shaped outer plate, and the arc-shaped clamping plate falls onto the bottom plate. At the same time, relying on the fact that the size of the arc-shaped clamping plate is larger than the distance between the two arc-shaped outer plates, the arc-shaped clamping plate is prevented from detaching.

[0008] The clamping device includes a turntable rotatably connected to the upper support and the lower support. On one side surface of the two turntables close to each other, grooves corresponding to the disc are provided. A limiting groove is provided on the outer surface of the disc, and a limiting block is fixed on the inner wall of the groove. The limiting block is slidably connected to the limiting groove. By limiting the disc through the limiting block and the limiting groove, the rotation of the turntable can drive the disc to rotate.

[0009] The clamping device further includes a convex block arranged inside the turntable. A chamber is provided on the side wall of the groove. The convex block is slidably connected to the chamber. An adjustment groove is provided on the upper surface of the turntable, and the adjustment groove is communicated with the chamber. An adjustment block is fixed on the upper surface of the convex block, and the adjustment block is slidably connected to the adjustment groove. By pushing the adjustment block to move, the convex block can be driven to move. At the same time, the adjustment groove can limit the adjustment block and further limit the movement of the convex block to prevent the convex block from disengaging from the chamber.

[0010] A return spring is fixed on the inner side surface of the convex block, and the other end of the return spring is fixed to the turntable. The elastic force of the return spring can push the convex block to reset and limit and block the movement of the disc.

[0011] Adjustment rods are fixed on one side surface of the two turntables away from each other, and the ends of the adjustment rods do not extend beyond the side surfaces of the upper support and the lower support, so as to prevent the upper support or the lower support from affecting the rotation of the adjustment rods after being fixed to an external platform.

[0012] Fixing plates for inserting bolts are fixed on the side surfaces of the upper support and the lower support, and the sizes of the fixing plates are smaller than the heights of the upper support and the lower support. The upper support and the lower support can be fixed to the platform by inserting bolts through the fixing plates.

[0013] The present utility model provides a dust-proof net for water conservancy construction, and the beneficial effects thereof are as follows:

[0014] 1. For the dust-proof net for water conservancy construction, the arc-shaped clamping plate is placed between the two arc-shaped outer plates through the top end of the arc-shaped outer plate. The arc-shaped clamping plate falls onto the bottom plate. At the same time, relying on the fact that the size of the arc-shaped clamping plate is larger than the distance between the two arc-shaped outer plates, the arc-shaped clamping plate is prevented from disengaging. The dust-proof net body can be pulled up by the two arc-shaped clamping plates, and multiple arc-shaped clamping plates cooperate with the upper support and the lower support to form a fence, solving the problem that the common dust-proof net for construction has poor fixing and restraining capabilities and is inconvenient to achieve enclosure and dust prevention in the prior art.

[0015] 2. For the dust-proof net for water conservancy construction, by setting the adjustment rod, the turntable can be driven to rotate. Through the rotation of the turntable, the disc can be driven to rotate, and then the rotating rod can be driven to rotate. The rotation of the rotating rod drives the arc-shaped clamping plate to rotate, and then the dust-proof net body is wound onto the arc-shaped outer plate for convenient next use, solving the problem that the common dust-proof net for construction has poor reusability.

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] Please refer to Figures 1 to 6 , an embodiment of the present utility model provides a dust-proof net for water conservancy construction, including an upper support 1 and a lower support 2. A clamping device 3 is arranged on the side surfaces of the upper support 1 and the lower support 2 close to each other. A rotating rod 4 is arranged between the upper support 1 and the lower support 2. Discs 5 are fixed at both ends of the rotating rod 4. A plurality of side plates 6 arranged in a circumferential manner are fixed on the outer surface of the rotating rod 4. An arc-shaped outer plate 7 is fixed on the outer side surface of the side plate 6. A dust-proof net body 8 is arranged outside the rotating rod 4. Arc-shaped clamping plates 9 are fixed at both ends of the dust-proof net body 8.

[0028] Please pay special attention to Figure 2 ,Figure 3 and Figure 6 , the size of the arc-shaped clamping plate 9 is larger than the distance between the two arc-shaped outer plates 7. A bottom plate 10 is fixed between two adjacent side plates 6. The bottom end of the arc-shaped clamping plate 9 is in contact with the bottom plate 10. The arc-shaped clamping plate 9 is placed between the two arc-shaped outer plates 7 through the top ends of the arc-shaped outer plates 7. The arc-shaped clamping plate 9 falls onto the bottom plate 10. At the same time, relying on the fact that the size of the arc-shaped clamping plate 9 is larger than the distance between the two arc-shaped outer plates 7, the arc-shaped clamping plate 9 is prevented from detaching. The clamping device 3 includes a turntable 301 rotatably connected to the upper support 1 and the lower support 2. On one side surface of the two turntables 301 close to each other, there are grooves corresponding to the disc 5. The outer surface of the disc 5 is provided with a limiting groove. The inner wall of the groove is fixed with a limiting block 302. The limiting block 302 is slidably connected to the limiting groove. Through the limitation of the disc 5 by the limiting block 302 and the limiting groove, the rotation of the turntable 301 can drive the disc 5 to rotate.

[0029] Please refer particularly to Figure 4 、 Figure 5 and Figure 6 , the clamping device 3 further includes a convex block 303 arranged inside the turntable 301. A chamber is provided on the side wall of the groove. The convex block 303 is slidably connected to the chamber. An adjustment groove is provided on the upper surface of the turntable 301. The adjustment groove is communicated with the chamber. An adjustment block 304 is fixed on the upper surface of the convex block 303. The adjustment block 304 is slidably connected to the adjustment groove. By pushing the adjustment block 304 to move, the convex block 303 can be driven to move. At the same time, the adjustment groove can limit the adjustment block 304 and further limit the movement of the convex block 303 to prevent the convex block 303 from detaching from the chamber.

[0030] Please refer particularly to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , a return spring 305 is fixed on the inner side surface of the convex block 303. The other end of the return spring 305 is fixed to the turntable 301. Through the elastic force of the return spring 305, the convex block 303 can be pushed to reset and limit and block the movement of the disc 5. Adjusting rods 11 are fixed on one side surface of the two turntables 301 away from each other. The end parts of the adjusting rods 11 do not extend beyond the side surfaces of the upper support 1 and the lower support 2 to prevent the rotation of the adjusting rods 11 from being affected after the upper support 1 or the lower support 2 is fixed to an external platform. Fixing plates 12 for inserting bolts are fixed on the side surfaces of the upper support 1 and the lower support 2. The sizes of the fixing plates 12 are smaller than the heights of the upper support 1 and the lower support 2. The upper support 1 and the lower support 2 can be fixed to the platform by inserting bolts through the fixing plates 12.

[0031] When the utility model is in use: the arc-shaped clamping plate 9 is placed between the two arc-shaped outer plates 7 through the top end of the arc-shaped outer plate 7. The arc-shaped clamping plate 9 falls onto the bottom plate 10. At the same time, relying on the fact that the size of the arc-shaped clamping plate 9 is greater than the distance between the two arc-shaped outer plates 7, the arc-shaped clamping plate 9 is prevented from disengaging. The dust-proof net body 8 can be pulled up by the two arc-shaped clamping plates 9. Multiple arc-shaped clamping plates 9 cooperate with the upper support 1 and the lower support 2 to form a fence, solving the problem that the fixing and restraining ability of the common construction dust-proof net in the prior art is poor and it is inconvenient to achieve enclosure and dust prevention.

[0032] When the dust-proof net body 8 needs to be wound up, rotate the adjusting rod 11. The adjusting rod 11 can drive the turntable 301 to rotate. Through the rotation of the turntable 301, the disc 5 can be driven to rotate, and then the rotating rod 4 can be driven to rotate. The rotation of the rotating rod 4 drives the arc-shaped outer plate 7 to rotate, and the arc-shaped outer plate 7 drives the arc-shaped clamping plate 9 to rotate, and then the dust-proof net body 8 is wound onto the arc-shaped outer plate 7 for convenient use next time, solving the problem that the common construction dust-proof net has poor reusability.

[0033] Then push the adjusting block 304. The movement of the adjusting block 304 drives the limiting block 302 to move. The movement of the limiting block 302 drives the convex block 303 to move. The convex block 303 releases the block on the disc 5, and the disc 5 disengages from the turntable 301, and then drives the rotating rod 4 to disengage from the upper support 1 and the lower support 2. Then pull out the rotating rod 4. The rotating rod 4 drives the arc-shaped outer plate 7 to disengage from the arc-shaped clamping plate 9 on the side where the bottom plate 10 is not fixed, and then the disassembly of the dust-proof net body 8 after winding up is realized, which is convenient for replacing and cleaning the dust-proof net body 8.
