DETAILED DESCRIPTION

[0022] The present application will be specifically introduced below in combination with the drawings and specific embodiments.

[0023] As Figures 1-12As shown, a water spraying dust suppression device for civil engineering environmental protection construction according to the present invention includes a base frame 1, a vertical frame 2 is longitudinally placed on the top of the base frame 1, and water buckets 3 are fixed on both sides of the base frame 1, and a water pump 4 is fixed on the water buckets 3, with the water pump 4 having a water suction pipe extending to the bottom of the water buckets 3; a top frame 5 is fixed on the top of the vertical frame 2, and blower frames 6 are fixed around the top of the top of the top frame 5; and a lifting component is provided inside the vertical frame 2 to expand the subsequent spraying height and range, thereby improving the comprehensive dust suppression of the civil engineering construction site. The lifting assembly includes a first motor 71 embedded on the back of the base frame 1. The lifting assembly also includes a main gear 72 fixed on the output shaft of the first motor 71, and an upper driven gear 73 is provided above the main gear 72. A first electric push rod 74 that rotates with the base frame 1 is fixed on the top of the upper driven gear 73. A lead screw 75 that rotates with the upright frame 2 is longitudinally arranged on the first electric push rod 74. After the meshing stroke between the upper driven gear 73 and the main gear 72 is adjusted to the correct position by the first electric push rod 74, the first motor 71 drives the lead screw 75 on the first electric push rod 74 to rotate linearly through the meshed main gear 72 and upper driven gear 73. A threaded sleeve 76 is threaded onto the lead screw 75, and a lifting plate 77 that slides with the upright frame 2 is sleeved on the outside of the threaded sleeve 76. The lead screw 75 drives the lifting plate 77 to rise and fall accordingly through the threaded sleeve 76, thereby expanding the subsequent spray height and range and improving the comprehensive dust suppression of the construction site. Vertical grooves 11 are provided around the four sides of the upright frame 2, and sliding ends that slide in cooperation with the vertical grooves 11 are provided around the four sides of the lifting plate 77. This serves to limit the sliding of the lifting plate 77 and also restricts the threaded sleeve 76 to prevent the lifting plate 77 from swinging or tilting, thereby improving its lifting stability.

[0024] like Figures 6-11 As shown, this invention provides a water spraying dust suppression device for civil engineering environmental protection construction, and a water distribution component is installed on the lifting assembly to achieve efficient dust suppression at the civil engineering construction site. The water distribution component includes a threaded hose 81 connected to the spray nozzle of a water pump 4, and an annular main pipe 82 connected to the top of the threaded hose 81. Each of the four ends of the annular main pipe 82 is connected to a booster branch pipe 83. Water is first supplied to the annular main pipe 82 by the threaded hose 81, and the lifting plate 77 drives several booster branch pipes 83 to rise and fall synchronously through the annular main pipe 82, expanding the... The dust suppression area is connected to a rotary joint 84 at the outer end of the pressurized branch pipe 83, and a connecting joint 85 rotating inside the rotary joint 84, which are kept in communication with each other. The outer end of the connecting joint 85 is connected to a water distribution head 86, and the outer end of the water distribution head 86 is connected to a direct spray head 87. The water in the several pressurized branch pipes 83 then reaches the several water distribution heads 86 in sequence through the rotary joint 84 and the connecting joint 85, and is sprayed by several direct spray heads 87 and side spray heads 12 to achieve a high-efficiency dust suppression effect at the civil construction site. The booster branch pipes 83 are distributed in a circumferential manner along the longitudinal axis of the annular main pipe 82 and diverge outward, and are made of metal pipe material, which is conducive to the full ejection of water in the several booster branch pipes 83. The top end of the water distribution head 86 is connected to the side spray head 12 used in conjunction with the straight spray head 87. The straight spray head 87 and the side spray head 12 are both designed with large-diameter atomizing nozzles, which enhances the spraying intensity of the several groups of straight spray heads 87 and side spray heads 12 and extends the spraying distance; The rotating assembly is arranged in the top frame 5 and rotates the water spraying of the water distribution assembly. The rotating assembly includes a second motor 91 fixed on the top frame 5. The rotating assembly further includes a transfer gear 92 fixed on the output shaft of the second motor 91. The transfer gear 92 is engaged with four planetary gears 93 that rotate in cooperation with the top frame 5. The second motor 91 drives the four planetary gears 93 to rotate linearly through the transfer gear 92. The outer sides of the four planetary gears 93 are engaged with a double-sided gear ring 94. The bottom circumference of the double-sided gear ring 94 is engaged with a bevel gear 95 that is sleeved on the water distribution head 86. The four planetary gears 93 drive the several groups of bevel gears 95 at the bottom of the double-sided gear ring 94 to rotate. The several groups of bevel gears 95 drive the straight spray heads 87 and the side spray heads 12 on the water distribution head 86 to rotate in a cyclone manner to efficiently reduce dust around. The top frame 5 is provided with an annular guide rail 13. The annular guide rail 13 is slidably arranged with a guide rail seat 14 that is fixedly connected to the double-sided gear ring 94 in a triangular equidistant manner. The guide rail seat 14 supports the rotation of the double-sided gear ring 94. The inner side of the double-sided gear ring 94 is fixedly connected with vertical gears that are engaged with the four planetary gears 93. The bottom circumference of the double-sided gear ring 94 is fixedly connected with bevel gears that are engaged with the bevel gears 95. This facilitates the stable rotation of the double-sided gear ring 94 and the effective rotation of the several groups of bevel gears 95. A drive gear 96 is fixed on the four planetary gears 93 through a rotating rod. The outer side of the drive gear 96 is engaged with a driven gear 97. The outer side of the four driven gears 97 is fixed with a blowing fan 15 that is used in conjunction with the blowing frame 6. The four planetary gears 93 drive the blowing fan 15 on the four driven gears 97 to rotate in the four blowing frames 6 through the drive gear 96, generating air pressure. The pressure in the four blowing frames 6 is blown to the area of the water distribution head 86 through the guide head 16, blowing the water mist sprayed by the straight spray heads 87 and the side spray heads 12 in a cyclone manner at a long distance. This further expands the dust reduction area of the construction site. The outer side of the blowing frame 6 is connected to the guide head 16 with a flow equalizing net and is inclined towards the water distribution head 86. This blows the water mist sprayed by the several groups of straight spray heads 87 and side spray heads 12 with wind power, further expanding the dust reduction area.

[0025] As Figure 12As shown, the water spraying and dust reducing device for civil environmental construction of the present application can not only meet the normal dust reducing function of the civil construction site, but also has the ability to kill mosquitoes in the summer mosquito season, resulting in workers at the civil construction site being bitten by mosquitoes and having a poor working environment. The two water buckets 3 are provided with stirring assemblies, and the stirring assemblies include a lower pinion 101 arranged below the main gear 72, a second electric push rod 102 fixed to the bottom of the lower pinion 101, and a differential gear 103 fixed to the bottom of the second electric push rod 102. The differential gear 103 is engaged with a bevel gear frame 104 on both sides. First, the second electric push rod 102 is controlled to adjust the engagement stroke between the lower pinion 101 and the main gear 72 to the right position, and then the first motor 71 drives the bevel gear frame 104 on both sides of the differential gear 103 to rotate linearly through the main gear 72 and the lower pinion 101 engaged in place. The outer sides of the two bevel gear frames 104 are engaged with a secondary bevel gear 105, and the secondary bevel gear 105 is fixed with a stirring frame 106 for mixing the medicament and water in the two water buckets 3. The two bevel gear frames 104 drive the two stirring frames 106 to rotate in the two water buckets 3, and the harmless medicament and water added therein are stirred and mixed, and then sprayed to the outside by the straight spray atomizing heads 87 and the side spray atomizing heads 12 to kill mosquitoes and improve the civil construction environment.

[0026] The working principle of the water spraying and dust reducing device for civil environmental construction is as follows: first, the first electric push rod 74 is controlled to open and drive the upper pinion 73 to move down and engage with the meshing part of the main gear 72, and then the first motor 71 is controlled to open and drive the threaded rod 75 on the upper pinion 73 engaged in place to rotate linearly in the positive direction through the main gear 72. The threaded rod 75 drives the annular manifold 82 on the lifting disc 77 to rise, and stretches the threaded hose 81 on the two water pumps 4. When the lifting disc 77 drives the several booster branch pipes 83 to reach the predetermined slot of the top frame 5 through the annular manifold 82, and the several bevel gears 95 reach the oblique tooth engagement position of the double-sided tooth ring 94, the first motor 71 is controlled to close, and then the first electric push rod 74 is controlled to close and drive the upper pinion 73 to move up and disengage from the meshing part of the main gear 72 to the initial position. Subsequently, the two water pumps 4 supply water in the two water buckets 3 through the water suction pipes to the annular manifold 82 through the two stretched threaded hoses 81, and then supply the water in the several water distribution heads 86 through the several booster branch pipes 83 in turn through the rotary joints 84 and the communication joints 85. The water in the several water distribution heads 86 is sprayed out in a straight and side spraying form by the several straight spray atomizing heads 87 and the side spray atomizing heads 12 to reduce dust. Then, the second motor 91 is first controlled to start and drive the four sets of planetary gears 93 to rotate linearly through the transfer gear 92, the four sets of planetary gears 93 drive the double-sided gear ring 94 to rotate through the vertical gear teeth, the oblique gear teeth of the double-sided gear ring 94 drive the water distribution heads 86 on the plurality of sets of oblique gear wheels 95 to rotate linearly, and then the linearly rotating water distribution heads 86 drive the direct injection atomizing heads 87 and the side injection atomizing heads 12 to atomize in the form of cyclone; At the same time, the four sets of planetary gears 93 drive the driven gears 97 on the four sets of drive gears 96 to rotate linearly, the four sets of driven gears 97 drive the four sets of air blowing fans 15 to rotate in the four sets of air blowing frames 6, and generate air pressure in the four sets of air blowing frames 6, and the air pressure in the four sets of air blowing frames 6 is blown to the area of the plurality of water distribution heads 86 through the four rows of air guide heads 16, and the water mist sprayed by the plurality of sets of direct injection atomizing heads 87 and side injection atomizing heads 12 is blown at a long distance, so as to expand the dust-settling area of the dust in the construction site; In the summer mosquito season, the two groups of water buckets 3 are first filled with harmless to human body and effective in killing mosquitoes, and then the second electric push rod 102 is controlled to start and drive the lower gear 101 to move to the meshing part of the main gear 72, and then the first motor 71 is controlled to start again and drive the meshed lower gear 101 to rotate linearly through the main gear 72, the lower gear 101 drives the bevel gear frame 104 on both sides of the differential gear 103 to rotate, and the two bevel gear frames 104 drive the stirring frame 106 on the two sets of bevel gears 105 to rotate linearly, and the water and the medicine in the two groups of water buckets 3 are stirred evenly, and the two groups of water pumps 4 are extracted again and sprayed to the outside by the plurality of sets of direct injection atomizing heads 87 and side injection atomizing heads 12, so as to meet the dust-settling demand and kill the mosquitoes in the construction environment.
