Description

Technical Field

[0001] The present application relates to the technical field of cooling and dust removal equipment, and in particular to a spray cooling and dust removal device for construction. Background Art

[0002] Dust pollution at construction sites is one of the main sources of air pollution. Dust prevention measures can reduce the impact of dust on the environment and surrounding residents and reduce the degree of air pollution. Dust suppression is often carried out by spraying enclosures or fog cannons, but the spraying area of ​​enclosures and fog cannons is limited, and can only be carried out in specific areas, with poor results. Especially during construction in summer, the temperature in the foundation pit may be very high, and workers working in high temperature environments for a long time are prone to health problems such as heat stroke. Therefore, a foundation pit skylight protection net has appeared on the market, which is a sunshade net placed above the foundation pit and a spray pipe placed under the sunshade net to prevent dust from drifting while blocking some ultraviolet rays to achieve the purpose of cooling and dust removal.

[0003] When the existing canopy is unfolded or retracted, it is connected to the supporting structure by hinges and can be opened or closed like a door, or the canopy can be rolled up on one or more crescent-shaped scrolls and retracted manually or electrically. However, it cannot be partially unfolded or closed. In addition, due to the situation that foundation pit construction often involves hoisting operations in one area to another area, the traditional integral unfolding or retracting canopy cannot be applied to such situations. Once the canopy is opened as a whole, the remaining construction locations cannot be dust-proofed and cooled. In addition, the current canopy may block the sprinkler pipe after being folded and stored, affecting the sprinkler operation. Summary of the invention

[0028] The present application is further described in detail below in conjunction with the accompanying drawings.

[0029] The present application discloses a spray cooling and dust removal device for construction. Figure 1-12As shown, it includes a protective canopy 1, multiple connecting parts 2, a base column 7, a folding component and a spray hose 11. The protective canopy 1 is used to cover the top of the foundation pit. An opening and closing component for opening and closing the protective canopy 1 is provided between two adjacent connecting parts 2. One opening and closing component corresponds to one protective canopy 1. When in use, multiple protective canopies 1 can be set according to the area of ​​the foundation pit. The shape of the protective canopy 1 is preferably rectangular, and a mesh structure can be made of high-strength and weather-resistant materials. The main purpose is to block and reduce the diffusion of dust during construction in the foundation pit, and to block a certain amount of sunlight to achieve a certain shading effect. During installation, a number of base columns 7 are set around the foundation pit. The base columns 7 can be fixed to the periphery of the foundation pit by pouring concrete at the bottom to support the connecting member 2, and an opening and closing assembly for opening and closing the protective canopy 1 is provided between two adjacent connecting members 2, and the opening and closing assembly includes a first connecting rack 3, a second connecting rack 31, and two telescopic members 4 arranged between the first connecting rack 3 and the second connecting rack 31, and one of the telescopic members 4 is fixedly connected to one end of the connecting rack, and one end of the other telescopic member 4 is provided with a first driving mechanism 5 for driving the telescopic member 4 to move on the connecting rack, the first connecting rack 3 is slidably connected to the inside of the connecting member 2, and the second connecting rack 31 is detachably connected to the connecting member 2, and when the connecting member 2 is connected, the first connecting rack 3 is connected to the connecting member 2. After the member 2 is installed above the base column 7, the first connecting rack 3 is installed between two adjacent connecting members 2, and then the second connecting rack 31 is installed at the end of the connecting member 2 by bolts or the like to fix it, wherein the connecting member 2 can be a member such as a channel steel, and the first connecting rack 3 is provided with a second driving mechanism 6 for driving the first connecting rack 3 to move. When the first driving mechanism 5 moves, the distance between the two telescopic members 4 is changed, and a transverse folding mechanism 8 is provided between the two telescopic members 4 to fold or unfold the protective canopy 1, so that the foundation pit under the protective canopy 1 leaks out. When the second driving mechanism 6 runs, the first connecting rack 3 and the second connecting rack 6 are connected. When the distance between the bars 31 is changed, the protective canopy 1 is longitudinally folded by the longitudinal folding mechanism 9 arranged between the first connecting rack 3 and the second connecting rack 31, and the first driving mechanism 5 and the second driving mechanism 6 can be operated simultaneously to store the protective canopy 1 to a corner. At the same time, the spray hose 11 is arranged under the folding component to spray water mist to suppress dust and cool the foundation pit. When the longitudinal folding mechanism 9 is folded, the spray hose 11 is pushed to a bent state, and the output end of the spray head 12 on the spray hose 11 faces outward to prevent the protective canopy 1 in the folded state from blocking the spray head 12 of the spray hose 11 and affecting the water mist spraying.

[0030] Further, such as Figure 4As shown, the first driving mechanism 5 includes connecting shafts 51 provided at both ends of the telescopic member 4, and the connecting shafts 51 are provided with first gears 52, and the two first gears 52 are respectively meshed with the first connecting rack 3 and the second connecting rack 31, and the end of the connecting shaft 51 close to one end of the second connecting rack 31 is provided with a first driving motor 53; Specifically, when the first drive motor 53 is running, the first gear 52 is driven to rotate through the connecting shaft 51, thereby realizing the change of the distance between the two telescopic parts 4 and folding or unfolding the protective skylight 1. The first drive motor 53 can be slidably connected to the second connecting rack 31 through the connecting plate. When the first gear 52 rotates, it can drive the first drive member to move synchronously.

[0031] Further, such as Figure 1 as well as Figure 6 As shown, the second driving mechanism 6 includes a second driving motor 61 disposed inside the first connecting rack 3, the output end of the second driving motor 61 is connected to a second gear 62, and a gear plate 63 meshing with the second gear 62 is disposed inside the connecting member 2; Specifically, when the second drive motor 61 drives the second gear 62 to rotate, the second gear 62 rotates on the gear plate 63, thereby adjusting the distance between the first connecting rack 3 and the second connecting rack 31. At the same time, the first connecting rack 3 has better stability during movement. The second drive motor 61 can adopt a dual-axis motor so that both ends of the first connecting rack 3 have driving force.

[0032] Among them, Figure 5 As shown, the telescopic member 4 is composed of a plurality of sliding tubes 41 which are slidably mounted on each other. When the first connecting rack 3 and the second connecting rack 31 are close to each other, the sliding tubes 41 can be sequentially received inside the adjacent sliding tubes 41, thereby changing the length of the telescopic member 4. At the same time, the cross-section of the sliding tube 41 is polygonal, ensuring that the two adjacent sliding tubes 41 will not rotate, so that when the first driving motor 53 drives one of the connecting shafts 51 to rotate, the telescopic member 4 can drive the other telescopic member 4 to rotate.

[0033] Further, such as Figure 4 as well as Fig.11 As shown, the transverse folding mechanism 8 includes a first contact box 81 and a first folding arm 82 hinged to both ends of the first contact box 81, and the other ends of the two first folding arms 82 are connected to a mounting block 83 rotatably connected to the connecting shaft 51. When one of the telescopic parts 4 approaches one end of the other telescopic part 4, the two first folding arms 82 swing relative to each other with the first contact box 81 as the center to achieve transverse folding, and there are at least two transverse folding mechanisms 8.

[0034] Further, such as Figure 4 as well as Fig.12As shown, the longitudinal folding mechanism 9 includes a second contact box 91 and second folding arms 92 hinged to both ends of the second contact box 91, and the other ends of the two second folding arms 92 are hinged to the first folding arms 82. When the first connecting rack and the second connecting rack 31 move relative to each other, the two first folding arms 82 are driven to move relative to each other, so that the two second folding arms 92 swing relative to each other with the second contact box 91 as the center.

[0035] Among them, Figure 8 As shown, a positioning arm 84 is provided on the first folding arm 82, and a hanging ring 85 is provided on the first folding arm 82 and the positioning arm 84. The protective canopy 1 is detachably connected to the first folding arm 82 and the positioning arm 84 via the hanging ring 85. When installing the protective canopy 1, the hanging ring 85 can be used to hang the protective canopy 1 at different positions in turn so as to replace the protective canopy 1. At the same time, the positioning arm 84 is provided to increase the fixing points of the protective canopy 1, so that the fixing effect of the protective canopy 1 is better, the stability of the protective canopy 1 is improved, and the possibility of the protective canopy 1 being blown off in windy weather is avoided.

[0036] Further, such as Figure 4 As shown, the first resistance box 81 is provided with a mounting groove 86, and the spray hose 11 is detachably connected to the lower end of the first resistance box 81 through the mounting groove 86. After the first connecting rack 3 and the second connecting rack 31 are installed on the connecting member 2, the spray hose 11 can be clamped in the mounting groove 86, and the second resistance box 91 can also be provided with a mounting groove 86. When the transverse folding mechanism 8 is folded, the first resistance box 81 will be driven to shift, and the spray hose 11 can be shifted synchronously at this time. When the longitudinal folding mechanism 9 is folded, the two second folding arms 92 drive the second resistance box 91 to move downward, and the spray hose 11 will be bent downward.

[0037] Among them, Figure 2 As shown, in order to avoid the spray hose 11 from breaking due to insufficient length when the spray hose 11 is bent, an automatic winding mechanism 21 is also provided on the connecting piece 2 for stretching the spray hose 11. When the spray hose 11 changes from a bent state to a straight state, the spray hose 11 automatically winds up the excess hose through the automatic winding mechanism 21 to avoid the spray hose 11 drooping. The automatic winding mechanism 21 utilizes a special spring loading mechanism. When the pipe is pulled, the spring is compressed to provide additional length for the pipe. When the pipe is no longer pulled, the spring releases the stored energy to automatically retract the pipe to its original position. This is a prior art and should be known to those skilled in the art. No further elaboration is given here. A water pump 13 is provided at the input end of the spray hose 11 and is connected to an external water supply device to provide a water source for spraying.

[0038] Furthermore, in order to better control the operation of the protective skylight 1 or the spray hose 11 in a certain area separately, a controller 22 is also provided. The controller 22 is electrically connected to the first drive motor 53, the second drive motor 61 and the water pump 13, and the protective skylight 1 and the spray hose 11 at a specific position can be opened and closed as needed.

[0039] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed. However, as long as it is within the scope of the claims of the present application, it shall be protected by the patent law.
