[0002] A canopy refers to a large shelter covering areas such as construction sites, usually made of canvas, mesh materials or other durable materials. It can block sunlight, rain, wind and sand, etc., providing a certain degree of shelter and protection for the construction site. A dust suppression canopy specifically refers to a three-dimensional dust control system for dust reduction, which is usually used at construction sites to cover the entire site, thereby reducing dust pollution during operations such as earth excavation. At the construction site, dust suppression canopies are usually used to block dust particles and reduce the impact of dust on the surrounding environment. Through the use of dust suppression canopies, the entire construction area can be effectively covered, and dust can be controlled within a certain range, thereby reducing the pollution of construction dust to the surrounding environment. At the same time, by reducing dust pollution, the dust suppression canopy can significantly improve the air quality of the construction site and its surrounding areas, which is beneficial to protecting the health of construction workers and surrounding residents.

[0003] In the prior art, when dust is reduced at a construction site by using a dust reduction curtain, the construction site is usually covered by the dust reduction curtain to prevent the spread of dust, thereby achieving the purpose of dust reduction. Since this dust reduction method is relatively simple, although the dust can be controlled within a certain range, the dust is still easy to drift in the construction site environment, thereby affecting the environment of the construction site and the health of the construction workers. Therefore, in order to solve the above problems, a dust isolation and dust reduction curtain for a construction site is proposed. Utility Model Content

[0022] The water pump 22 and telescopic cylinder 210 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described here in detail.

[0023] A construction site dust isolation and dust reduction canopy includes a frame, the frame including a support frame 1, an inner surface of the support frame 1 is fixedly connected to a top frame 11, and an inner side of the top frame 11 is provided with a curtain 12. The support frame 1 is provided to support the top frame 11 and the curtain 12, and the curtain 12 is provided to cover the construction site, thereby reducing the spread of dust.

[0024] A dust reduction mechanism is provided on the surface of the support frame 1, and the dust reduction mechanism includes a nozzle 2, which is movably connected to the inner side of the support frame 1, and a nozzle 21 is fixedly connected to the lower surface of the nozzle 2. A water pump 22 is installed on one side of the support frame 1, and a delivery pipe 23 is fixedly connected to the surface of the water pump 22. The end of the delivery pipe 23 away from the water pump 22 is fixedly connected to a hose 24. Through the setting of the water pump 22, an external water source can be delivered to the nozzle 2, and then the construction site can be sprayed through the nozzle 21, thereby achieving dust reduction, which can improve the dust reduction effect of the curtain 12.

[0025] Furthermore, the dust reduction mechanism also includes a gear 25, which is fixedly connected to the surface of the nozzle 2, and a fixed plate 26 is fixedly connected to the surface of the support frame 1. A slide groove 27 is provided on the inner side of the fixed plate 26, and a slider 28 is movably connected to the inner side of the slide groove 27. The surface of the slider 28 is fixedly connected to a rack plate 29, and a telescopic cylinder 210 is fixedly installed on the surface of the fixed plate 26. Through the cooperation of the rack plate 29 and the gear 25, the spraying range of the nozzle 21 can be changed, and then the nozzle 21 can better suppress the spread of dust, improve the dust reduction efficiency, and facilitate the improvement of the environmental quality of the construction site.

[0026] Furthermore, one end of the hose 24 away from the delivery pipe 23 is fixedly connected to the nozzle 2, one end of the slider 28 is movably connected to the slide groove 27, and the other end of the slider 28 is fixedly connected to the rack plate 29. Through the cooperation of the slide groove 27 and the slider 28, the rack plate 29 can be limited, which can prevent the rack plate 29 from being offset under the action of the telescopic cylinder 210, making it easier for the rack plate 29 to move stably and transmit the gear 25.

[0027] Furthermore, the rack plate 29 is movably connected to the slide block 28 and the slide groove 27, and the rack plate 29 is fixedly connected to the output end of the telescopic cylinder 210. The telescopic cylinder 210 is extended and retracted to drive the rack plate 29 to move back and forth, and then the gear 25 can rotate back and forth under the action of the rack plate 29, so that the nozzle 2 drives the nozzle 21 to move accordingly, which can expand the spraying range of the nozzle 21 and improve the dust reduction effect.

[0028] Furthermore, a mounting mechanism is provided on the inner side of the top frame 11, which includes a fixing frame 3, which is fixedly connected to the inner wall of the top frame 11, a screw 31 being threadedly connected to the inner side of the fixing frame 3, and a connecting plate 32 being movably connected to the top of the screw 31, and a first protrusion 33 being fixedly connected to the upper surface of the connecting plate 32, and a first groove 34 being provided on the inner wall of the fixing frame 3, and a second protrusion 35 being fixedly connected to the inner wall of the fixing frame 3, and a second groove 36 being provided on the inner side of the connecting plate 32, and a limiting rod 37 being fixedly connected to the inner wall of the fixing frame 3. By rotating the screw 31, the connecting plate 32 is moved upward, and the curtain 12 can be clamped by the inner wall of the fixing frame 3 and the connecting plate 32. At the same time, the curtain 12 will enter the inner side of the first groove 34 and the second groove 36, so that the clamping effect of the curtain 12 is better, thereby facilitating the installation and use of the curtain 12.

[0029] Furthermore, the first protrusion 33 and the second protrusion 35 are staggered with the first groove 34 and the second groove 36, and the connecting plate 32 and the limiting rod 37 are movably connected. Through the setting of the limiting rod 37, the connecting plate 32 can be limited, and the connecting plate 32 can be prevented from being offset under the action of the screw 31, thereby ensuring that the connecting plate 32 can stably perform vertical movement.

[0030] Working principle: When in use, the water pump 22 is electrically connected to an external power source, and the staff starts the water pump 22 by pressing a switch. By connecting the water pump 22 to an external water source, the water pump 22 can draw water in and allow the water to enter the nozzle 2 through the delivery pipe 23 and the hose 24, and be sprayed out through the nozzle 21, thereby achieving the effect of dust reduction. The telescopic cylinder 210 is electrically connected to an external power source, and the staff starts the telescopic cylinder 210 by pressing a switch. The telescopic cylinder 210 is extended and retracted, which can drive the rack plate 29 to move, so that the rack plate 29 can move on the inner side of the slide groove 27 through the slider 28, and then the gear 25 will rotate forward and reverse under the action of the rack plate 29, so that the nozzle 2 will move accordingly under the action of the gear 25, which can change the spraying angle and range of the nozzle 21;

[0031] The curtain 12 is passed through the middle of the fixing frame 3 and the connecting plate 32, and then the screw 31 is rotated. The connecting plate 32 is limited by the limiting rod 37 and will move vertically inside the fixing frame 3 under the action of the screw 31. When the connecting plate 32 and the inner wall of the fixing frame 3 are in contact with each other, the curtain 12 can be clamped by the fixing frame 3 and the connecting plate 32. At the same time, the first protrusion 33 and the second protrusion 35 will enter the inner sides of the first groove 34 and the second groove 36, and then the curtain 12 will enter the first groove 34 and the second groove 36, so that the curtain 12 can be clamped, thereby achieving a better fixing effect.
