Description

Technical Field

[0001] The utility model relates to the technical field of spray dust reduction, in particular to a construction site spray dust reduction device. Background Art

[0002] Spray dust reduction at construction sites is a very important environmental protection measure during the construction process. Its necessity is mainly reflected in that a large amount of dust is often generated at construction sites. These dusts not only pose a threat to the health of workers, but also affect the quality of life of surrounding residents; dust pollution may also have a negative impact on the environment, affecting the quality of soil and water sources. By spray dust reduction, the suspended particulate matter in the air can be effectively reduced, and the impact on the environment can be reduced.

[0003] At present, the main methods for dust reduction at construction sites are: arranging a circle of fences around the construction site, and then installing a spray system on the fences for spraying water mist; in addition, dust reduction can be carried out by covering the land with a covering net, planting plants, etc. However, for local construction sites within the construction site, there is a lack of corresponding dust reduction devices. Summary of the Utility Model

[0023] As Figure 1 shown, this embodiment provides a construction site spray dust reduction device, including a flatbed truck 1, a water tank 2, a water pump 3, and a spray structure.

[0024] Specifically, in order to facilitate the movement of the entire device, four wheels are provided at the bottom of the flatbed cart 1, and each wheel is provided with a locking member for locking the wheel to prevent the flatbed cart 1 from moving randomly.

[0025] Specifically, a support plate 44 is respectively arranged at the top of both ends of the flatbed cart 1. The water tank 2 and the water pump 3 are both fixedly arranged on the top of the flatbed cart 1. Between the two support plates 44, the spraying structure is erected above the flatbed cart 1 through the two support plates 44. The spraying structure includes a water delivery pipe 41 and a plurality of spraying pipes 42. The water delivery pipe 41 is parallel to the long axis of the flatbed cart 1. The plurality of spraying pipes 42 are arranged in an array along the direction of the water delivery pipe 41. The water delivery pipe 41 is connected to the water pump 3 through a water extraction pipe 45. The water pump 3 is connected to the water tank 2. The bottom of each spraying pipe 42 is connected to the water delivery pipe 41. A nozzle 43 is arranged at the top of the spraying pipe 42. The water pump 3 is used to transport the water in the water tank 2 to the water delivery pipe 41, and then to the plurality of spraying pipes 42, and finally sprayed into the surrounding environment through the nozzles 43, so as to achieve the effect of dust reduction.

[0026] In order to reduce dust in construction environments of different ranges, preferably, in this embodiment, the distance between a plurality of nozzles 43 is adjusted through a distance adjustment structure, such as Figures 2 - 4 shown. The distance adjustment structure includes a linear travel mechanism 51, an adjustment plate 52, a guide rod 53, and a plurality of columns 54. The adjustment plate 52 is arranged above the water tank 2. Both ends of the adjustment plate 52 are slidably connected to the corresponding support plates 44. The sliding direction of the adjustment plate 52 is consistent with the short axis direction of the flatbed cart 1. The adjustment plate 52 is provided with a plurality of guide grooves 521. The distance between any two adjacent guide grooves 521 is equal, and the distance between both ends of two adjacent guide grooves 521 is different. The shapes of all the guide grooves 521 form a trumpet shape. The travel mechanism 51 is arranged at one end of the water tank 2 for horizontally moving the adjustment plate 52. There are many ways to implement the travel mechanism 51, such as by driving a lead screw through a motor. The guide rod 53 is fixedly arranged between the two support plates 44 and is parallel to the water delivery pipe 41. A sliding sleeve 55 is arranged at the top of the column 54. The sliding sleeve 55 is slidably matched with the guide rod 53. The bottom of the column 54 is matched with the corresponding guide groove 521. The spraying pipe 42 is arranged at the top of the corresponding sliding sleeve 55. The bottom of each spraying pipe 42 is connected to the water delivery pipe 41 through a hose 421. The function of the hose 421 is to facilitate the adjustment of the distance between the nozzles 43.

[0027] More specifically, as Figure 4 shown, the spraying pipe 42 is arranged in a Z shape, and the corners of the Z-shaped spraying pipe 42 are all right angles. The hose 421 is arranged in a U shape. The hose 421 is located below the water delivery pipe 41. When adjusting the distance between the nozzles 43, the hose 421 moves accordingly and its shape also changes.

[0028] The usage method is as follows: When it is necessary to adjust the spacing between multiple nozzles 43, the stroke mechanism 51 horizontally moves the adjusting plate 52. Since the column 54 is restricted by the guide rod 53, when the adjusting plate 52 moves, it will cause the column 54 to move linearly only along the guide rod 53, and the spacing between two adjacent columns 54 expands or contracts, and the spacing between two adjacent nozzles 43 expands or contracts accordingly.

[0029] More specifically, as Figure 2 , Figure 3 shown, in order to improve the stability of the adjusting plate 52 and the column 54, the following measures are taken in this embodiment: The support plate 44 is provided with a horizontal through groove 441, the end of the adjusting plate 52 is provided with a straight plate 522, the outer end of the straight plate 522 is provided with a baffle 523, the straight plate 522 is slidably fitted in the corresponding through groove 441, the baffle 523 is closely attached to the outer wall of the support plate 44, there is a gap between the bottom surface of the adjusting plate 52 and the top surface of the water tank 2, the bottom of the column 54 is successively provided with a first circular plate 541, a cylinder 542 and a second circular plate 543, the adjusting plate 52 is located between the first circular plate 541 and the second circular plate 543, the cylinder 542 is located in the gap between the bottom surface of the adjusting plate 52 and the top surface of the water tank 2, and the cylinder 542 is matched with the corresponding guide groove 521.

[0030] In order to prevent the water suction pipe 45 from obstructing the movement of the straight plate 522 and the baffle 523, in this embodiment, the water suction pipe 45 is arranged outside one of the support plates 44, and both ends of the water suction pipe 45 penetrate through the support plate 44 and are respectively connected to the water delivery pipe 41 and the water pump 3.

[0031] The above embodiments are only used to illustrate the technical idea and characteristics of the present invention, and do not represent the only or limit the present invention. Those skilled in the art should understand that without departing from the scope of the present invention, various changes or equivalent replacements made to the present invention all belong to the protection scope of the present invention.
