Description

Technical Field

[0001] This utility model relates to the field of construction site dust suppression technology, and in particular to an environmentally friendly dust suppression spray device for construction sites. Background Technology

[0002] In today's construction industry, the pace of urban construction is accelerating, and various construction sites are springing up like mushrooms after rain. This inevitably generates a large amount of dust. Dust not only seriously pollutes the air quality at the construction site, but also spreads to the surrounding areas with airflow. Therefore, effectively controlling dust at construction sites has become an important environmental protection aspect that must be emphasized in construction.

[0003] Currently, construction sites employ various dust suppression methods. Traditional manual water spraying, relying on manual operation of water trucks or handheld sprayers, is simple and easy to implement, but inefficient and limited by the range of manual operation, making it difficult to fully cover the entire construction site. Some large construction sites use fixed sprinkler systems, which can suppress dust in a certain area, but their fixed installation locations cannot be flexibly adjusted according to changes in the construction area. Once the construction area changes, the dust suppression effect is greatly reduced. Some mobile spray dust suppression equipment, while possessing a certain degree of flexibility, is extremely inconvenient to move and place in complex terrains such as potholes and muddy construction sites, and has poor stability, failing to meet the diverse construction needs of construction sites.

[0004] Current dust suppression equipment has many problems in practical applications. In terms of deployment flexibility, existing equipment cannot flexibly adjust its position and angle according to the real-time construction situation on the construction site. It lacks adjustability and adaptability and is difficult to place stably on uneven ground. As a result, the equipment can only be installed in specific areas and cannot be used to suppress dust in areas where new dust is generated in a timely manner. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an environmentally friendly dust suppression spray device for construction sites, which can effectively solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an environmentally friendly dust suppression spray device for construction sites, including a water tank. The outer cylindrical surface of the water tank has four upper telescopic legs arranged in a circumferential array. The outer side of the lower end of each upper telescopic leg is threaded with a fastening sleeve. A lower telescopic leg is sleeved on the inner side of each upper telescopic leg. The lower end of each lower telescopic leg is provided with a parting fixing leg. A rotating spray bar is provided on the upper surface of the water tank. The top of the rotating spray bar is hinged with several movable nozzles in a circumferential array. A counterweight is provided at the end of each movable nozzle away from the hinge end. A spray bar gear is provided at the lower end of the rotating spray bar. A pressure booster is provided on the lower side of the water tank, and the pressure booster is connected to the inside of the water tank.

[0008] Furthermore, the split-type fixed leg includes a rotating component, the upper side of which is slidably connected to the lower telescopic leg, and the lower side of which is provided with a first semi-circular component.

[0009] Furthermore, a second semicircular part is provided at the lower end of the first semicircular part, and a third semicircular part is provided at the lower end of the second semicircular part.

[0010] Furthermore, the movable nozzle has a nozzle water hole at one end that is hinged to the rotating spray bar, and a spring is hinged to the rotating spray bar at the other end of the movable nozzle away from the nozzle water hole.

[0011] Furthermore, a motor is provided on the upper surface of the water tank, a waterproof cover is provided on the outside of the motor, and the output end of the motor passes through the waterproof cover and is provided with an output gear, which meshes with the spray bar gear.

[0012] Furthermore, a pedal is provided on the side of the rotating component, and a pointed cone is provided below the side of the pedal away from the rotating component.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model is equipped with a flexibly adjustable support structure. The upper and lower telescopic legs can adjust their height according to the ground conditions to adapt to different terrains. The split fixed legs can rotate flexibly and fit closely to various complex ground surfaces. With the fastening sleeve for reinforcement, it can ensure that the device can be placed stably on different terrains of the construction site. This design allows the dust suppression spray device to be easily moved and deployed in the construction site, greatly improving the flexibility of the device layout and significantly enhancing the dust suppression effect.

[0015] 2. This utility model features a unique nozzle working mechanism. The movable nozzle is hinged to the rotating spray bar, with a nozzle water hole at one end and a spring connecting the other end. During operation, the centrifugal force generated by the water flow drives the nozzle to rotate, connecting the spray bar water hole with the nozzle water hole, allowing water to be sprayed out smoothly to form a mist. When operation stops, the spring pulls the nozzle back to its original position, and the side wall of the nozzle blocks the spray bar water hole. This design ensures stable spraying during operation and prevents water leakage and impurities from entering when not in operation, thus avoiding water waste, reducing the risk of nozzle clogging, and extending the nozzle's service life.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figure 1-3This first embodiment of the present invention provides an environmentally friendly dust suppression spray device for construction sites, comprising a water tank 1. Four upper telescopic legs 2 are arranged in a circumferential array on the outer cylindrical surface of the water tank 1. A fastening sleeve 22 is threaded onto the outer side of the lower end of each upper telescopic leg 2. Rotating the fastening sleeve 22 adjusts the tightness between the leg and the ground, thereby enhancing the overall stability of the device. A lower telescopic leg 21 is sleeved on the inner side of each upper telescopic leg 2. The upper and lower telescopic legs 2 and 21 work together to allow for flexible height adjustment of the device to adapt to different terrains. A split-type fixing leg 3 is provided at the lower end of the lower telescopic leg 21. The split-type fixing leg 3 can be adjusted according to the ground shape, allowing the device to be better fixed on various complex ground surfaces. A rotating spray bar 4 is provided on the upper surface of the water tank 1. The rotating spray bar 4 can rotate 360 ​​degrees to expand the spray coverage area. Several movable nozzles 42 are hinged in a circumferential array at the top of the rotating spray bar 4. The movable nozzles 42 can rotate flexibly to achieve multi-angle spraying.

[0026] A counterweight is provided at the end of the movable nozzle 42 away from the hinge end. The counterweight helps the movable nozzle 42 maintain balance during rotation and improves the stability of the spray. A spray bar gear 41 is provided at the lower end of the rotating spray bar 4. The spray bar gear 41 is used to transmit power and drive the rotating spray bar 4 to rotate. A pressure booster 6 is provided on the lower side of the water tank 1. The pressure booster 6 is connected to the inside of the water tank 1. The pressure booster 6 can increase the water pressure, so that the water can be better sprayed from the nozzle to form a spray.

[0027] The split-type fixed leg 3 includes a rotating part 31. The upper side of the rotating part 31 is slidably connected to the lower telescopic leg 21. This sliding connection allows the rotating part 31 to flexibly adjust its angle. The lower side of the rotating part 31 is provided with a first semi-circular part 32. The first semi-circular part 32 can initially fit against the ground and play a certain supporting and fixing role.

[0028] The lower end of the first semicircular part 32 is provided with a second semicircular part 33, which further increases the contact area with the ground and improves the fixing effect. The lower end of the second semicircular part 33 is provided with a third semicircular part 34, which fits tightly with the ground and enhances the stability of the device on different terrains.

[0029] Example 2

[0030] Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0031] The movable nozzle 42 is hinged to the rotating spray bar 4 at one end and has a nozzle water hole 421. The nozzle water hole 421 is the channel for water to spray out. The movable nozzle 42 is hinged to the rotating spray bar 4 at the other end away from the nozzle water hole 421 and has a spring 44. When the device stops working, the spring 44 pulls the movable nozzle 42 back to its original position to prevent water leakage and impurities from entering.

[0032] A motor 52 is installed on the upper surface of the water tank 1. The motor 52 provides power to the entire spraying device. A waterproof cover 5 is installed on the outside of the motor 52. The waterproof cover 5 can protect the motor 52 and prevent it from being damaged by water splashing in. The output end of the motor 52 passes through the waterproof cover 5 and is provided with an output gear 51. The output gear 51 meshes with the spray bar gear 41 and drives the rotating spray bar 4 to rotate through gear transmission.

[0033] A pedal 35 is provided on the side of the rotating component 31, which is convenient for the operator to step on. A pointed cone 351 is provided on the lower side of the pedal 35 away from the rotating component 31. The pointed cone 351 can be inserted into the ground when the pedal 35 is stepped on, further enhancing the fixing effect of the device.

[0034] The remaining structure is the same as that in Example 1.

[0035] The specific operating principle of this utility model is as follows:

[0036] First, during the device preparation stage, the water tank 1 serves as a water storage component, storing the water required for dust suppression. The four upper telescopic legs 2 and lower telescopic legs 21, arranged in a circumferential array on the outer cylindrical surface of the water tank 1, adjust the overall height of the device by relative sliding to adapt to different construction site terrains. After adjusting the height, the fastening sleeve 22 is rotated. Because the inner wall of the fastening sleeve 22 has threads that match the outer side of the upper telescopic legs 2, the fastening sleeve 22 moves upward along the threads during rotation, creating a squeezing effect on its inner wall, causing the inner diameter of the upper telescopic legs 2 to shrink, thereby tightly clamping the lower telescopic legs 21 inside. The split-type fixing leg 3 is installed at the lower end of the lower telescopic legs 21, and the rotating part 31 can slide relative to the lower telescopic legs 21, flexibly adjusting the angle according to the ground shape. The first semicircular part 32, the second semicircular part 33, and the third semicircular part 34 are connected in sequence, closely fitting the ground, further improving the stability of the device on complex terrain.

[0037] The motor 52 is mounted on the upper surface of the water tank 1. The outer waterproof cover 5 protects the motor 52 from water splashes and other effects. The output end of the motor 52 passes through the waterproof cover 5 and is connected to the output gear 51. The output gear 51 meshes with the spray bar gear 41 at the lower end of the rotating spray bar 4 to form a power transmission structure. The pressure booster 6 is mounted on the lower side of the water tank 1 and communicates with the inside of the water tank 1 to increase the water pressure. The movable nozzle 42 is mounted on the top circumferential array position of the rotating spray bar 4 by means of hinge. A counterweight is installed away from the hinge end to ensure rotational balance. A nozzle water hole 421 is opened near the hinge end. A spring 44 is also hinged between the movable nozzle 42 and the rotating spray bar 4.

[0038] Secondly, when the device starts working, the motor 52 is started. The motor 52 drives the output gear 51 to rotate. Since the output gear 51 meshes with the spray bar gear 41, it drives the rotating spray bar 4 to rotate around its central axis, expanding the spray coverage area. At the same time, the pressurizer 6 starts working, pressurizing the water in the water tank 1. The pressurized water flows through the spray bar water hole 43 to the movable nozzle 42. The centrifugal force generated by the water flow pushes the movable nozzle 42 to rotate around the hinge point, so that the spray bar water hole 43 and the nozzle water hole 421 are connected. Water is sprayed out from the nozzle water hole 421 to form a spray, realizing the dust suppression function.

[0039] Finally, when the device stops working, the motor 52 stops running, and the rotating spray bar 4 no longer rotates. At this time, the movable nozzle 42 loses the propulsion of the centrifugal force of the water flow. Under the tension of the spring 44, the movable nozzle 42 rotates back to its initial position. The side wall of the nozzle blocks the water hole 43 of the spray bar, preventing water leakage from the water tank 1 and avoiding water waste. It also prevents external impurities from entering the nozzle, protecting the nozzle and extending the service life of the device.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
