Description
Technical Field
[0001] The invention relates to the technical field of engineering construction, and in particular to an energy-saving dust suppression device for construction. Background Art
[0002] In the process of modern urbanization, construction projects are frequently carried out, and the large amount of dust generated during the construction process not only causes serious pollution to the environment, but also directly affects the quality of life of surrounding residents. In order to improve this situation, reducing the dust generated during the construction process has become an important issue that the construction industry must face. The main purpose of dust reduction is to reduce the content of particulate matter in the air, prevent air pollution, protect the health of construction site workers, and comply with the requirements of relevant environmental protection laws and regulations.
[0003] At present, common dust reduction methods include but are not limited to wet dust reduction (such as sprinkling water, spraying), dry dust reduction (such as covering dust-proof nets) and mechanical dust reduction (such as using dust removal equipment). Among them, wet dust reduction is widely used because of its simple operation and obvious effect. Spray pipes are set on the fences outside the construction area. For some open construction environments, spray trucks are used for targeted spray dust reduction. Water is atomized into fine particles through high-pressure nozzles. These fine water droplets can effectively absorb dust particles in the air, thereby achieving the effect of dust reduction.
[0004] However, although spray trucks can effectively control dust problems at construction sites, their manufacturing and use costs are relatively high. On the one hand, the spray truck itself is expensive; on the other hand, in actual applications, the spray truck needs to run continuously and requires high energy support to maintain its working state. In addition, the maintenance and upkeep of the spray truck is also a considerable expense. Summary of the invention
[0005] The purpose of the present invention is to provide an energy-saving construction dust suppression device, which is small in size, low in cost, does not require consumption of additional energy when in use, and is a more economical and environmentally friendly dust suppression equipment.
[0006] The above technical objectives of the present invention are achieved through the following technical solutions: an energy-saving construction dust suppression device, comprising a column, a water delivery channel arranged along the length direction of the column is opened in the middle of the column, a pipe port connected to the lower end of the water delivery channel is arranged outward at the lower end of the column, a rotating seat is arranged at the upper end of the column, a vertical rotating table capable of vertical rotation is rotatably connected to the rotating seat, a lower water inlet cavity is arranged at the upper end of the vertical rotating table, the lower end of the lower water inlet cavity is connected to the upper end of the water delivery channel through a water inlet hose, an upper water outlet shell is connected above the lower water inlet cavity, and the front and rear sides of the lower water inlet cavity are connected to the upper water outlet shell through connecting strips;
[0007] A sliding cavity is reserved between the lower water inlet cavity and the upper water outlet shell, and an alternating slide bar that can slide left and right is slidably connected in the sliding cavity, and water outlet holes are provided on the left and right sides of the upper end of the lower water inlet cavity, and conducting holes are provided at both ends of the alternating slide bar, and the spacing between the two conducting holes is greater than the spacing between the two water outlet holes, so that only one conducting hole can always be connected to one water outlet hole, and two water flow driving cavities corresponding to the water outlet holes are opened upward from the lower end of the upper water outlet shell, and a driving shaft is rotatably connected in each water flow driving cavity, and a spiral blade is arranged on the outer side of each driving shaft, and the spiral directions of the spiral blades in the two water flow driving cavities are opposite;
[0008] The upper end of the upper water outlet shell is rotatably connected to a horizontal rotating table that can rotate horizontally, a transmission cavity is arranged on the upper part of the upper water outlet shell, a transmission shaft is connected to the lower end of the horizontal rotating table, and a transmission gear extending into the transmission cavity is connected to the lower end of the transmission shaft, and the upper end of each driving shaft extends into the transmission cavity and is provided with a driving gear meshing with the transmission gear, and the left and right sides of the lower end edge of the horizontal rotating table are downwardly provided with outwardly expanding extrusion baffles, and after one end of the alternating slide bar contacts the corresponding extrusion baffle, it can be gradually squeezed and slid into the sliding cavity, a spray pipe is arranged outwardly on the upper end of the horizontal rotating table, and a spray nozzle is connected to the free end of the spray pipe, and the upper part of the water flow driving cavity and the spray pipe are connected through a water outlet hose.
[0009] By adopting the above technical solution, after the column is installed, a high-pressure water pipe is connected to the pipe port, and the high-pressure water flows into the lower water inlet cavity along the water delivery channel and the water inlet hose. First, the alternating slide bar is slid to one end so that a conducting hole faces the water outlet hole and the water flow driving cavity. At this time, the water flows into the water flow driving cavity, flows into the spray pipe through the water outlet hose, and then sprays out high-pressure water mist through the spray nozzle;
[0010] The water flow drives the spiral blade to rotate, and drives the driving gear to rotate through the transmission shaft. The driving gear drives the transmission gear to rotate, and the rotation of the transmission gear drives the horizontal rotating table to rotate, thereby driving the spray nozzle to rotate to one side and spray. When the horizontal rotating table rotates to the end of one side, the extrusion baffle squeezes one end of the alternating slide bar back into the sliding cavity, and the other end slides out of the sliding cavity, switching to another conducting hole facing the water outlet and water flow driving cavity on the other side, so that the water flows into the other water flow driving cavity, driving the other spiral blade to rotate, so that the other driving gear drives the transmission gear to rotate in the opposite direction, and finally drives the spray nozzle to rotate to the other side and spray, and so on and so forth, so that the spray nozzle can swing back and forth left and right to spray and reduce dust.
[0011] The present invention is further configured as follows: outer rotating plates are arranged upward on the left and right sides of the rotating seat, and inner rotating plates are arranged downward on the left and right sides of the vertical rotating platform, wherein one of the inner rotating plates passes through the corresponding outer rotating plate and is connected to a worm gear, and the corresponding outer rotating plate is rotatably connected to a worm meshing with the worm gear, the worm gear and the worm gear meet self-locking conditions, a driving head is arranged at one end of the worm gear, and a non-circular driving socket is opened inwardly on the driving head.
[0012] By adopting the above technical solution, when the inclination angle of the spray needs to be adjusted, the worm is rotated to drive the worm wheel to rotate, which drives the vertical rotating platform to rotate, so that the spray nozzle can be tilted upward at a corresponding angle.
[0013] The present invention is further configured as follows: the worm gear is an incomplete worm gear that is approximately fan-shaped.
[0014] The present invention is further configured such that: the cross section of the driving socket is rectangular.
[0015] The present invention is further configured as follows: a movable groove is downwardly opened at the upper end of the column, and the lower end of the water inlet hose is connected to the upper end of the water delivery channel at the bottom of the movable groove.
[0016] The present invention is further configured as follows: two spray pipes are disposed outwardly from the upper end of the horizontal rotating table, the two spray pipes are distributed in a V shape, and each spray pipe is connected to the upper part of the corresponding water flow driving chamber through a water outlet hose.
[0017] The present invention is further configured as follows: a mounting plate is provided at the lower end of the column, and a plurality of mounting holes are provided through the mounting plate.
[0018] In summary, the present invention has the following beneficial effects:
[0019] First, the present invention realizes automatic spray coverage through a simple mechanical structure. It has a simple structure, lower cost, is more convenient for promotion and use, and reduces dependence on traditional spray vehicles. Because its structural design cleverly utilizes the kinetic energy of water to convert into mechanical energy, the drive device swings back and forth to spray, and no additional energy is consumed, thereby achieving the purpose of energy saving and emission reduction.
[0020] Secondly, through the automatic adjustment angle of the spray nozzle and the reciprocating swing spray function of the horizontal rotating table, the device can achieve a wider spray coverage area, ensure a more uniform and comprehensive dust reduction effect, and effectively improve the dust reduction efficiency.

A rotating seat 2 is provided at the upper end of the column 1, and the rotating seat 2 is rotatably connected to a vertical rotating platform 3 that can rotate vertically. An outer rotating plate 21 is provided upward on both the left and right sides of the rotating seat 2, and an inner rotating plate 31 rotatably connected to the corresponding outer rotating plate 21 is provided downward on both the left and right sides of the vertical rotating platform 3, and one of the inner rotating plates 31 passes through the corresponding The outer rotating plate 21 is connected to a worm wheel 32, which is an incomplete worm wheel 32 that is approximately fan-shaped. The corresponding outer rotating plate 21 is rotatably connected to a worm 22 that meshes with the worm wheel 32. The worm wheel 32 and the worm 22 meet the self-locking condition. A driving head 23 is provided at one end of the worm 22. The driving head 23 has a rectangular driving socket 24 inwardly opened. The cross-section of the driving socket 24 is not circular so that it can be driven to rotate by the plug shaft. The worm wheel 32 is driven to rotate by rotating the worm 22, thereby driving the vertical rotating platform 3 to rotate.
[0033] A strip-shaped lower water inlet cavity 4 is provided at the upper end of the vertical rotating table 3, a movable groove 15 is opened downwardly at the upper end of the column 1, and a water inlet hose 41 is connected to the lower end of the lower water inlet cavity. The lower end of the water inlet hose 41 is connected to the upper end of the water delivery channel 13 at the bottom of the movable groove 15, and an upper water outlet shell 5 is connected to the upper part of the lower water inlet cavity 4. The front and rear sides of the lower water inlet cavity 4 are connected to the upper water outlet shell 5 through a connecting strip 42. A sliding cavity 43 is left between the lower water inlet cavity 4 and the upper water outlet shell 5, and an alternating slide bar 6 that can slide left and right is slidably connected in the sliding cavity 43. A water outlet hole 44 is opened on the left and right sides of the upper end of the lower water inlet cavity 4, and a conducting hole 61 is opened at both ends of the alternating slide bar 6. The spacing between the two conducting holes 61 is greater than the spacing between the two water outlet holes 44, so that only one conducting hole 61 can always be connected to one water outlet hole 44. Two water flow driving cavities 51 corresponding to the water outlet holes 44 are opened upward from the lower end of the upper water outlet shell 5, and each water flow driving cavity 51 is rotatably connected to a driving shaft 52, and a spiral blade 53 is arranged on the outer side of each driving shaft 52, and the spiral directions of the spiral blades 53 in the two water flow driving cavities 51 are opposite.
[0034] The upper end of the upper water outlet shell 5 is rotatably connected to a horizontal rotating table 7 that can rotate horizontally. A transmission chamber 54 is arranged on the upper part of the upper water outlet shell 5. A transmission shaft 71 is connected to the lower end of the horizontal rotating table 7. The lower end of the transmission shaft 71 is connected to a transmission gear 72 that extends into the transmission chamber 54. The upper end of each drive shaft 52 extends into the transmission chamber 54 and is provided with a driving gear 55 that meshes with the transmission gear 72. The left and right sides of the lower end edge of the horizontal rotating table 7 are downwardly provided with an outwardly expanding extrusion baffle 73.

Two spray pipes 8 are arranged outward from the upper end of the horizontal rotating table 7. The two spray pipes 8 are distributed in a V shape. The free end of each spray pipe 8 is connected to a spray nozzle 81. The upper part of each water flow driving chamber 51 is connected to the corresponding spray pipe 8 through a water outlet hose 82.

The high-pressure water flow enters the lower water inlet cavity 4 along the water delivery channel 13 and the water inlet hose 41. First, the alternating slide bar 6 is slid to one end so that a conducting hole 61 is opposite to the water outlet hole 44 and the water flow driving cavity 51. At this time, the water flow enters the water flow driving cavity 51, and the water flow flows into the spray pipe 8 through the water outlet hose 82, and then sprays out high-pressure water mist through the spray nozzle 81;
[0036] The water flow drives the spiral blade 53 to rotate, and drives the driving gear 55 to rotate through the transmission shaft 71. The driving gear 55 drives the transmission gear 72 to rotate. The rotation of the transmission gear 72 drives the horizontal rotating table 7 to rotate, thereby driving the spray nozzle 81 to rotate to one side and spray. When the horizontal rotating table 7 rotates to the end of one side, the extrusion baffle 73 squeezes the extended end of the alternating slide 6 back into the sliding cavity 43, and the other end slides out of the sliding cavity 43, switching to another conducting hole 61 facing the water outlet hole 44 and the water flow driving cavity 51 on the other side, so that the water flows into the other water flow driving cavity 51, driving the other spiral blade 53 to rotate, so that the other driving gear 55 drives the transmission gear 72 to rotate in the opposite direction, and finally drives the spray nozzle 81 to rotate to the other side and spray. This is repeated, so that the spray nozzle 81 swings back and forth left and right to spray and reduce dust.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed.
