Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a dust reduction enclosure for building construction. Background Art

[0002] Urban development is inseparable from construction. Many construction sites are located around urban residential areas. Construction sites cannot be separated from sand, cement and soil. These fine dusts are easily blown up by the wind, threatening the health of construction workers and affecting the work efficiency of construction sites. They pollute the urban environment and seriously affect the lives of surrounding residents.

[0003] Spray dust suppression is a new type of dust suppression technology. Its principle is to use the particles generated by the spray system. Because they are extremely small and have basically zero surface tension, they can quickly absorb various dust particles in the air when sprayed into the air, forming effective dust control. It has a good effect on dust control and dust reduction in large open areas. On construction sites, sprinkler heads are generally installed on the fence to achieve dust suppression and prevent dust from spreading outward.

[0004] The problem with the related technology is that the fence is generally fixed on the periphery of the construction site. When construction is carried out in the city, there is no shortage of crowded places outside the construction site. When the sprinkler heads installed on the fence spray water mist, part of the water mist will inevitably spray outside the construction site, affecting the line of sight of pedestrians and easily forming puddles on the road surface.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application discloses a dust reduction enclosure for construction. Figure 1 A construction dust reduction enclosure includes an enclosure plate 1 and a support frame 2 for providing stable support for the enclosure plate 1. The support frame 2 is arranged on both sides of the enclosure plate 1, and includes a vertical support 21, a horizontal support 22 and an oblique support 23, wherein the vertical support 21 extends in the height direction and is perpendicular to the ground, and both sides of the enclosure plate 1 are fixed on the vertical support 21, the horizontal support 22 is laid on the ground and connected to the vertical support 21, and is fixed by embedded fasteners, and the oblique support 23 is arranged between the vertical support 21 and the horizontal support 22 to form a triangular stable structure.

[0033] In actual application, the enclosure is made up of multiple enclosure panels 1, and the area enclosed by the enclosure is the construction space. The above-mentioned horizontal support 22 is fixed to the side of the vertical support 21 facing the construction space and extends toward the construction space. The side of the enclosure panel 1 facing away from the construction space is the outer surface, which is in contact with the outside world.

[0034] Reference Figure 1 A spray assembly 3 is provided on one side of the enclosure plate 1. The spray assembly 3 includes a high-pressure water pipe 31 and an atomizing nozzle 32. One end of the high-pressure water pipe 31 is connected to a water supply source (not shown in the drawings). A plurality of atomizing nozzles 32 are provided and are evenly distributed along the length direction of the enclosure plate 1. Preferably, the distance between two adjacent atomizing nozzles 32 is 2 meters. Water is introduced into the high-pressure water pipe 31 through the water supply source, and the water is ejected through the atomizing nozzle 32 to form water mist that spreads around, adsorbs the dust floating in the air and then drops to the ground, thereby achieving the dust reduction effect.

[0035] The spray assembly 3 is preferably arranged on the side of the enclosure plate 1 facing the construction space. A support 4 is provided on the enclosure plate 1. The support 4 has a circular insertion hole. The high-pressure water pipe 31 is inserted into the insertion hole for fixation.

[0036] It is understandable that a power element, such as a high-pressure water pump, should be provided between the water supply source and the high-pressure water pipe 31 to pump the water flow from the water supply source into the high-pressure water pipe 31 .

[0037] Reference Figure 1 and Figure 2 An inclined water retaining plate 5 is arranged on the side of the enclosure plate 1 opposite to the construction space, and the upper end of the water retaining plate 5 is inclined in the direction away from the construction space to form a certain angle with the vertically arranged enclosure plate 1. When the water mist diffuses outside the construction space, the water retaining plate 5 can intercept the water mist in most of the range to prevent it from falling on pedestrians or falling on the ground to form a puddle.

[0038] Furthermore, a reflux member 6 is provided below the water baffle plate 5. The reflux member 6 is a plate-like structure with an L-shaped cross-section, one end of which is fixed on the enclosing plate 1 to form a reflux chamber 7 with an upper end open between the enclosing plate 1. The lower end of the water baffle plate 5 extends into the reflux chamber 7, so that the water mist intercepted on the water baffle plate 5 can be gathered into a water flow and flow into the reflux chamber 7.

[0039] Furthermore, reflux holes 8 are provided at both ends of the reflux member 6, and a reflux pipe 9 is installed at the lower end of the reflux hole 8. The reflux pipe 9 is connected to the water supply source, so that the water flowing into the reflux chamber 7 flows through the reflux hole 8 and the reflux pipe 9 into the water supply source to achieve recovery.

[0040] Reference Figure 3 A first guide portion 10, a second guide portion 11 and a guide groove 12 are arranged in the return member 6, wherein the first guide portion 10 and the second guide portion 11 are respectively arranged on both sides of the guide groove 12, and the first guide portion 10 and the second guide portion 11 are inclined upward at one end away from the guide groove 12, so that the water flow flowing into the reflux chamber 7 can be retained in the guide groove 12 along the inclined surfaces of the first guide portion 10 and the second guide portion 11.

[0041] The guide groove 12 extends along the length direction of the return member 6, and has an inverted V-shaped cross-section, with the middle portion being higher than the two ends. The above-mentioned return holes 8 are formed at both ends of the guide groove 12, so that when water flows into the guide groove 12, it can flow along the inclined surface of the guide groove 12 into the return holes 8.

[0042] Furthermore, a drainage groove 13 is opened on the side surface of the water baffle plate 5 facing the reflux chamber 7. There are several drainage grooves 13 and they are distributed at intervals. The lower end of each drainage groove 13 passes through the end surface of the water baffle and is connected with the reflux chamber 7. The drainage groove 13 has the effect of converging and draining, reducing the residence time of water mist on the water baffle plate 5, avoiding the adsorption of more dust and impurities, and making the water mist more efficiently recovered.

[0043] Reference Figure 1 and Figure 4 , connecting parts 15 are formed on both sides of the lower end of the water baffle plate 5, and a rotating seat 14 is arranged at the position corresponding to the connecting part 15 on the inner wall of the reflux member 6. The rotating seat 14 is composed of two relatively distributed plates and an axis arranged between the two plates. Matching axial holes are respectively opened on the two connecting parts 15, and the axis is passed through the axial holes, so that the connecting part 15 can rotate relative to the rotating seat 14, that is, the water baffle plate 5 can rotate relative to the reflux member 6.

[0044] Furthermore, an adjustment rope 17 is connected to one side of the water baffle 5 located at the rotation axis, and the end of the adjustment rope 17 away from the water baffle 5 is bypassed by the enclosure board 1 and vertically arranged in the construction space. Workers in the construction space can control the rotation angle of the water baffle 5 by pulling the adjustment rope 17. In order to adjust the friction between the contact part of the rope 17 and the enclosure board 1 when pulling the adjustment rope 17, a fixed pulley 16 is installed on the enclosure board 1, and the adjustment rope 17 is wound around the surface of the fixed pulley 16. A take-up drum 18 is installed on the side surface of the support frame 2 facing the construction space. When adjusting the rotation angle of the water baffle 5, part of the length of the adjustment rope 17 between the water baffle 5 and the fixed pulley 16 is on the surface, and the excess part of the adjustment rope 17 can be wound on the take-up drum 18 and fixed.

[0045] Furthermore, a spring 19 is provided between the water baffle 5 and the return member 6. The spring 19 extends along the width direction of the return member 6 and is provided on the other side of the rotation axis of the water baffle 5 opposite to the connection point of the adjustment rope 17. When the spring 19 is in natural extension, the angle between the water baffle 5 and the enclosure 1 is the largest; when the water baffle 5 is rotated to reduce the angle, the spring 19 is compressed. After the adjustment is completed, one end of the adjustment rope 17 is fixed on the take-up drum 18, so that the position of the water baffle 5 is fixed, and the spring 19 always remains in a compressed state; when the adjustment rope 17 is untied from the take-up drum 18, the adjustment rope 17 can move, the spring 19 restores its deformation and pushes the lower end of the water baffle 5 to move toward the enclosure 1, and the upper end of the water baffle 5 moves toward the outside of the construction space, so that the angle between the water baffle 5 and the enclosure 1 becomes larger.

[0046] It is understandable that in order to prevent the water baffle 5 from being out of control after the adjustment rope 17 is untied and colliding with the return member 6 during rotation, the adjustment rope 17 should be grasped by hand and a small force should be applied thereto during the process of untying the adjustment rope 17 to control the movement speed of the water baffle 5.

[0047] The implementation principle of the dust reduction enclosure for construction in the embodiment of the present application is as follows: during construction, the water supply source pumps water into the high-pressure water pipe 31 through a high-pressure water pump, and the water source circulates in the high-pressure water pipe 31, and forms water mist through the atomizing nozzle 32 installed on the high-pressure water pipe 31 and sprays it to the surroundings, absorbing the dust generated during construction, and playing a role in dust reduction. During the dust reduction process, the water retaining plate 5 is set on the enclosure plate 1 at a certain inclination angle, and most of the water mist sprayed out of the construction space is intercepted on the water retaining plate 5, and converges into a water flow in the drainage groove 13 to flow to the reflux chamber 7. Under the action of the first guide part 10, the second guide part 11 and the guide groove 12, the water flow is guided to the reflux hole 8, and finally flows back to the water supply source through the reflux pipe 9, realizing the recycling of water resources.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
