Description

Technical Field

[0001] This utility model relates to the field of dust suppression spray technology, and in particular to an intelligent nozzle for an intelligent environmental dust suppression spray device for building construction sites. Background Technology

[0002] Construction sites are prone to generating dust, threatening worker health and impacting the surrounding environment. Common dust suppression spray systems use water pumps to draw pressurized water and deliver it through pipes. There are two operational methods: one is for workers to hold the water hose and flexibly suppress dust; the other is to fix the water hose to a dust suppression vehicle, utilizing its mobility to suppress dust over a large area. Both methods spray water mist from nozzles, allowing the water mist to combine with dust and settle, thus creating a clean construction environment.

[0003] In existing technologies, when the weather is cold, if the water in the pipes is not drained in time after the equipment is used, the pipes will be subjected to enormous pressure due to internal freezing, which can easily lead to damage such as cracking or deformation. After the existing equipment is turned off, the water inside the equipment flows back through the pipes to be drained from the equipment. However, the water may freeze inside the equipment pipes, which will significantly shorten the overall service life of the equipment, increase construction costs, and reduce construction efficiency.

[0004] Therefore, it is necessary to provide a new intelligent nozzle for an environmentally friendly dust suppression spray device at construction sites to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an intelligent nozzle with an intelligent construction site environmental protection dust suppression spray device that can quickly drain water accumulated inside the equipment.

[0006] The intelligent nozzle of the intelligent construction site environmental protection dust suppression spray device provided by this utility model includes: a pipe body threadedly connected to the intelligent nozzle, the inner wall of the pipe body is provided with a tapered tube that fits tightly with it and slides along its vertical direction, the end of the tapered tube with a smaller inner diameter is close to the intelligent nozzle, and multiple drainage holes are opened at equal angles on the side wall of the end of the pipe body away from the intelligent nozzle.

[0007] The converging tube slides towards the end of the tube body closer to the smart nozzle due to the impact of the water flow from bottom to top, while the converging tube slides towards the end of the tube body away from the smart nozzle due to gravity without being impacted by the water flow.

[0008] Preferably, the end of the pipe body away from the intelligent nozzle is provided with a telescopic baffle, and the drain hole is provided with a groove at a symmetrical length for the output end of the telescopic baffle to slide, and the telescopic baffle controls the opening and closing state of the drain hole.

[0009] Preferably, the telescopic baffle is placed in a base that is fixedly connected to the pipe body, and the outer side of the telescopic baffle is provided with a heater for heating it.

[0010] Preferably, the tapered tube is cylindrical or frustum-shaped, and the inner wall of the tapered tube is always funnel-shaped.

[0011] Preferably, when the tapered tube is placed at the end of the tube body away from the intelligent nozzle, the maximum height of the side wall of the tapered tube that is in contact with the inner wall of the tube body is always level with the end of the drain hole that is close to the inner wall of the tube body.

[0012] Preferably, the inclination angle of the drain hole is 5° to 10°.

[0013] Compared with related technologies, the intelligent nozzle of the intelligent construction site environmental protection dust suppression spray device provided by this utility model has the following beneficial effects:

[0014] This utility model provides an intelligent nozzle for an intelligent construction site environmental protection dust suppression spray device. The water inside the tube flows naturally due to gravity through the converging tube and is quickly discharged through the drain hole, effectively improving the drainage efficiency of the device. At the same time, the converging tube slides on the inner wall of the tube, which can automatically scrape off the particles attached to the inner wall of the tube, avoiding the accumulation of scale due to long-term uncleaning and improving the durability of the device.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] Please see Figures 1 to 4 This utility model provides an intelligent nozzle for an intelligent dust suppression spray device for construction sites. The intelligent nozzle of the intelligent dust suppression spray device for construction sites includes:

[0023] The pipe body 1 is threadedly connected to the intelligent nozzle. The inner wall of the pipe body 1 is provided with a tapered tube 2 that fits tightly to it and slides along its vertical direction. The tapered tube 2 is cylindrical or frustum-shaped, and the inner wall of the tapered tube 2 is always funnel-shaped. The end of the tapered tube 2 with a smaller inner diameter is close to the intelligent nozzle. By using the different diameters at both ends of the tapered tube 2, the water output rate at the end of the tapered tube 2 that is close to the nozzle is higher, which can effectively improve the water supply efficiency of the pipe body 1 to the nozzle.

[0024] The converging tube 2 slides towards the end of the tube body 1 that is close to the smart nozzle due to the impact of the water flow from bottom to top. The converging tube 2 slides towards the end of the tube body 1 that is not impacted by the water flow and is driven by gravity. The material of the converging tube 2 is copper. Copper has good corrosion resistance and thermal conductivity, which can effectively resist the corrosion of chemicals in the water, reduce the risk of water leakage, extend the service life of the converging tube 2, and enhance the durability and stability of the equipment.

[0025] Multiple drainage holes 3 are opened at equal angles on the side wall of the end of the pipe body 1 away from the smart nozzle. When the tapered tube 2 is placed at the end of the pipe body 1 away from the smart nozzle, the maximum height of the side wall of the tapered tube 2 that is in contact with the inner wall of the pipe body 1 is always level with the end of the drainage hole 3 that is close to the inner wall of the pipe body 1. This avoids the maximum height of the outer side of the tapered tube 2 that is in close contact with the pipe body 1 from blocking the water inlet end of the drainage hole 3. The level state can better guide the water inside the pipe body 1 and prevent water from remaining on the top surface of the tapered tube 2, effectively improving the drainage performance inside the equipment.

[0026] The inclination angle of the drainage hole 3 is 5° to 10°, which facilitates the smooth and rapid drainage of groundwater and effectively improves the ability of water to flow out of the hole under the action of gravity. At the same time, the smaller angle can also prevent a large amount of external impurities from entering to a certain extent. Because the hole opening is relatively closer to the horizontal state, impurities are not easy to roll directly into it, reducing the possibility of external impurities and dust clogging the inside of the drainage hole 3.

[0027] A telescopic baffle 5 is provided at the end of the pipe body 1 away from the intelligent nozzle. A groove 4 is provided at the symmetrical length of the drain hole 3 for the output end of the telescopic baffle 5 to slide. The telescopic baffle 5 controls the opening and closing state of the drain hole 3. When the intelligent nozzle is working, the flow of the drain hole 3 is closed by the telescopic baffle 5, which can increase the water pressure inside the pipe body 1 and better supply water to the nozzle. When the nozzle finishes working, the flow of the drain hole 3 is opened by the telescopic baffle 5, so that the water accumulated inside the pipe body 1 can be discharged quickly, which effectively improves the intelligence and ease of use of the equipment.

[0028] The telescopic baffle 5 is placed in the base 6 which is fixedly connected to the pipe body 1. The outer side of the telescopic baffle 5 is provided with a heater 7 for heating it. When the weather is cold, the telescopic baffle 5 can be heated by the heater 7, and the heat can be transferred to the pipe body 1 through the heat conduction of the telescopic baffle 5, so that the thin ice that may be generated inside the pipe body 1 melts. The heating temperature of the heater 7 is always 10℃, which avoids the equipment from not working properly due to the cold weather and improves the stability of the equipment.

[0029] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
