Description

Technical Field

[0001] The present application relates to the field of dust reduction in construction, and in particular to a construction dust reduction device. Background Art

[0002] At present, during construction, fences are set up around the construction site to separate the construction site from the outside world, thereby reducing the impact of construction on the surrounding environment of the construction site. The corresponding dust suppression device is often composed of multiple atomizing nozzles connected in series and installed on the top of the fence. The atomizing nozzle sprays water in a vertical direction, and the height of the water nozzle is fixed. The water mist is dispersed in mid-air, so that the dust in the construction site adheres to the water droplets in the air, thereby controlling the dust at the construction site.

[0003] However, since dust has the characteristic of floating with the wind, the dust will flow with the wind, and the water mist sprayed by the atomizing nozzle will also be affected by the wind. Therefore, when the wind is strong and the wind direction is from inside the construction site to outside the construction site, the height of the dust may increase with the increase of wind and then exceed the dust reduction range of the atomizing nozzle, which makes it difficult for existing dust reduction devices to achieve a good dust reduction effect on dust in windy weather. Summary of the invention

[0004] In order to maintain a good dust reduction effect on the dust at the construction site even in windy weather, the present application provides a construction dust reduction device.

[0005] The construction dust reduction device provided in this application adopts the following technical solution:

[0006] It includes multiple dust reduction units, a main pipeline, a water pump and multiple branch pipelines. The water pump is used to supply water to the main pipeline. The multiple branch pipelines are respectively connected to the main pipeline. The dust reduction unit includes a base, a fixed pipe, a nozzle and a changing assembly. The fixed pipe includes a connecting part and a water spraying part. The nozzle is installed on the water spraying part, and the connecting part is installed on the base. One end of the water spraying part away from the nozzle is hinged to one end of the connecting part away from the base. A torsion spring is arranged on the hinge shaft between the water spraying part and the connecting part. One end of the torsion spring is connected to the connecting part, and the other end of the torsion spring is connected to the water spraying part. The changing assembly is used to change the angle between the water spraying part and the connecting part. One end of the branch pipeline away from the main pipeline is penetrated through the connecting part and connected to the nozzle.

[0007] By adopting the above technical scheme, the water pump transports water from the water source into the main pipe, and then transports it to the nozzle through the branch pipe on the main pipe, and then sprays it out through the nozzle, thereby achieving the effect of reducing dust within the construction site. The torsion spring makes the angle between the water spray part and the connecting part always have a tendency to change while the water spray part is hinged at the connecting part. Under this tendency, the angle between the connecting part and the water spray part will not remain unchanged. The changing direction component changes the angle between the water spray part and the connecting part by overcoming the tendency of the angle change between the water spray part and the connecting part, thereby making the water spraying angle of the water spray part change according to the size of the wind at the construction site, so that it still has a good dust reduction effect on the dust at the construction site in windy weather.

[0008] Optionally, the direction changing component includes a wind sensor, a limit member, a driving member and a controller, the wind sensor is installed on the connecting part and is electrically connected to the controller, the limit member is installed on the base and can slide on the base; the driving member is electrically connected to the controller, and is used to drive the limit member to slide back and forth on the base, the limit member abuts against the water spray part, and the angle between the water spray part and the connecting part changes as the limit member slides on the base.

[0009] By adopting the above technical solution, the wind sensor is used to sense the wind force at the construction site and transmit the relevant sensor information to the controller. The controller is electrically connected to the driving member so that when the wind force reaches a certain value, the driving member will drive the limiting member to move on the base. Since the water spray part abuts against the limiting member and a torsion spring is provided between the water spray part and the guide part, the angle between the water spray part and the connecting part changes with the position of the limiting member, thereby changing the water outlet angle of the nozzle on the water spray part, and the direction changing component enables the water spray part to change the water outlet angle with the wind force.

[0010] Optionally, a guide portion is provided on the limiting member, and a guide groove is provided on the base at a position corresponding to the guide portion, and the guide portion is located in the guide groove and can be slidably matched with the guide groove.

[0011] By adopting the above technical solution, the guide portion on the limiting member is located in the guide groove, so that the limiting member can only slide along the extension direction of the guide groove during movement, and the guide groove plays a guiding role for the limiting member.

[0012] Optionally, the guide groove is a C-shaped groove, and the guide portion is adapted to the C-shaped groove.

[0013] By adopting the above technical solution, the C-shaped groove prevents the limiting member from falling out of the guide groove during the process of abutting against the water spraying part, thereby playing a limiting role for the limiting member.

[0014] Optionally, a power supply component is also provided on the base, and the power supply component includes a solar panel and a battery. The solar panel is used to provide electrical energy to the battery, and the controller and the drive component are respectively connected to the battery.

[0015] By adopting the above technical solution, the solar panels replenish the battery with electricity through sunlight, thereby saving electricity consumption, while the battery provides energy for the controller and the drive components.

[0017] By adopting the above technical solution, the clamping assembly enables the base to be installed above the construction site fence. Under the action of the second torsion spring, the connecting rod makes the clamping plate press against the side wall of the fence, thereby fixing the base on the fence.

[0018] Optionally, the telescopic rod includes telescopic rod one and telescopic rod two, telescopic rod one is fixedly connected to the base and sleeved on telescopic rod two, and one end of telescopic rod two close to telescopic rod one is provided with a plurality of positioning holes spaced apart along the length direction of the telescopic rod, and a positioning piece is installed on the telescopic rod one, and the positioning piece passes through the telescopic rod one and is threadedly matched with any one of the positioning holes.

[0019] By adopting the above technical solution, the staff can adjust the extended length of the telescopic rod 2 on the telescopic rod 1 according to the thickness of the enclosure, thereby being suitable for enclosures of different thicknesses. At the same time, the positioning piece passes through the outer wall of the telescopic rod 1 and is connected to the positioning hole on the telescopic rod 2, so that the extended length of the telescopic rod 2 on the rope rod 1 will not change easily.

[0020] Optionally, an anti-slip layer is provided at one end of the clamping plate away from the connecting rod.

[0021] By adopting the above technical solution, the protective pattern increases the friction between the clamping plate and the enclosure surface, so that the clamping plate will not slip easily on the enclosure surface.

[0022] In summary, the present application includes at least the following beneficial technical effects:

[0023] 1.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] The present application embodiment discloses a construction dust suppression device, referring to Figure 1 , including multiple dust reduction units 1, a main pipeline 2, a water pump 3 and multiple branch pipelines 4, wherein all the dust reduction units 1 are spaced apart above the fence 28 around the construction site, the main pipeline 2 is parallel to the length direction of the fence 28 and is located below the fence 28, the main pipeline 2 is connected to the water pump 3, and all the branch pipelines 4 are connected to the main pipeline 2 at one end, and the other ends of all the branch pipelines 4 are respectively connected to different dust reduction units 1.

[0031] Reference Figure 2-3 The dust reduction unit 1 includes a base 5, a fixed pipe 6, a nozzle 7, and a change-of-direction assembly 10. The fixed pipe 6 and the change-of-direction assembly 10 are respectively installed on the base 5. The fixed pipe 6 includes a hinged connection part 8 and a water spray part 9, wherein the connection part 8 is vertically installed on the base 5, and the nozzle 7 is installed on the water spray part 9. The nozzle 7 is an atomizing nozzle 7. The end of the branch pipe 4 away from the main pipe 2 is passed through the connection part 8 from the bottom of the base 5 and is connected to the nozzle 7 on the water spray part 9. A torsion spring 29 is also installed on the hinge shaft between the water spray part 9 and the connection part 8. One end of the torsion spring 29 is connected to the connection part 8, and the other end of the torsion spring 29 is connected to the water spray part 9.

[0032] The direction-changing assembly 10 includes a wind sensor 11, a stopper 12, two sets of driving members 13 and a controller 14. The wind sensor 11 is mounted on the outer wall of the connecting portion 8, and the driving member 13, the controller 14 and the stopper 12 are mounted on the base 5. The driving member 13 is an electric push rod, which is connected to the stopper 12, and the controller 14 is electrically connected to the wind sensor 11 and the driving member 13, respectively, so that the wind sensor 11 can convert the sensed wind force into an electrical signal and transmit it to the controller 14, and the controller 14 receives the wind from the wind sensor 11. The driving member 13 is controlled by the electrical signal of the device 11, so that the driving member 13 can drive the limiting member 12 to slide on the bottom plate, that is, the sliding distance of the limiting member 12 on the base 5 is inversely proportional to the size of the wind force, and the water spraying part 9 abuts against the limiting member 12 from the bottom of the limiting member 12 under the action of the torsion spring 29, so that the closer the limiting member 12 is to the connecting part 8, the smaller the angle between the water spraying part 9 and the connecting part 8, and the greater the distance between the limiting member 12 and the connecting part 8, the greater the angle between the water spraying part 9 and the connecting part 8, thereby realizing the change of the water outlet angle of the nozzle 7.

[0033] A guide groove 16 is also provided on the base 5. The guide groove 16 extends from a direction away from the connecting portion 8 to a direction close to the connecting portion 8. The guide groove 16 is a C-shaped groove. A guide portion 15 is provided on the limiting member 12. The guide portion 15 is adapted to the guide groove 16. This allows the guide groove 16 to not only play a guiding role but also prevent the limiting member 12 from falling out of the guide groove 16 in a direction perpendicular to the upper surface of the base 5 due to the reaction force of the water spray portion 9 when it abuts against the water spray portion 9.

[0034] Reference Figure 2 and Figure 3Furthermore, in order to enable the controller 14 and the driving member 13 to be used normally, a power supply component 17 is also provided on the base 5. The power supply component 17 includes a solar panel 18 and a battery 19. The solar panel 18 is used to absorb solar energy and supply the electric energy generated by the solar energy to the battery 19, while the controller 14 and the driving member 13 are respectively connected to the battery 19. This ensures that even if there is a power outage at the construction site, when the wind blows up dust, the driving member 13 and the controller 14 can still remain in working condition to ensure the normal implementation of the dust reduction function.

[0035] In order to enable the base 5 to be conveniently fixed above the fence 28, four groups of clamping assemblies 20 are further arranged on the base 5, and the four groups of clamping assemblies 20 are symmetrically distributed along the midline of the length direction of the base 5. One group of clamping assemblies 20 includes a telescopic rod 21, a connecting rod 22 and a clamping plate 23, wherein the telescopic rod 21 includes a telescopic rod 1 24 and a telescopic rod 2 25, one end of the telescopic rod 1 24 is fixedly connected to the base 5, and the other end of the telescopic rod 1 24 is sleeved on the telescopic rod 25, and the telescopic rod 25 can slide in the telescopic rod 1 24, so that the extension distance of the telescopic rod 25 on the telescopic rod 1 24 can be adjusted according to the thickness of the fence, and the applicability is wide.

[0036] The end of the telescopic rod 25 away from the telescopic rod 1 24 is hinged with the connecting rod 22, and a torsion spring 230 is installed on the hinge axis of the connecting rod 22 and the telescopic rod 25. One end of the torsion spring 230 is connected to the telescopic rod 25, and the other end of the torsion spring 230 is connected to the connecting rod 22. Under the action of the torsion spring 230, the end of the connecting rod 22 away from the telescopic rod 25 always has a tendency to rotate from the bottom of the base 5 to the base 5, and the clamping plate 23 is ball-hinged with the end of the connecting rod 22 away from the telescopic rod 25.

[0037] When the staff needs to use the clamping assembly 20 to fix the base 5 above the fence, they only need to break apart the connecting rods 22 of the four groups of clamping assemblies 20 respectively, and then place the base 5 above the enclosure 28. At this time, under the action of the torsion spring 230, the connecting rod 22 drives the clamping plate 23 to abut against the surface of the enclosure 28, thereby achieving the fixation of the base 5 above the fence.

[0038] In order to increase the friction between the clamping plate 23 and the surface of the enclosure 28 , an anti-skid layer 31 is provided on the clamping plate 23 . The anti-skid layer 31 may be made of materials such as rubber, and knurled anti-skid patterns are provided on the anti-skid layer 31 .

[0039] In order to prevent the extension distance of the second telescopic rod 25 on the first telescopic rod 24 from changing easily and affecting the clamping stability, a plurality of positioning holes 26 are provided on the second telescopic rod 25 at intervals along the length direction of the second telescopic rod 25. At one end of the first telescopic rod 24 close to the second telescopic rod 25, a positioning member 27 is inserted. The positioning member 27 can be a bolt. After passing through the first telescopic rod 24, the bolt is threadedly engaged with any one of the positioning holes 26 on the second telescopic rod 25, thereby fixing the extension distance of the second telescopic rod 25 on the first telescopic rod 24.

[0040] The implementation principle of the embodiment of this application is as follows: First,掰开 the connecting rod 22 of the clamping assembly 20 on the base 5, then fix the base 5 above the enclosure 28. After all the dust reduction assemblies are fixed, start the water pump 3. The water pump 3 conveys the water in the water source to the main pipeline 2, and then through the main pipeline 2 to the branch pipeline 4, and finally sprays out through the nozzle 7, thereby realizing the function of dust reduction.

[0041] When the wind speed sensor 11 converts the wind speed at the construction site into an electrical signal and transmits it to the controller 14, the controller 14 first displays it by converting the electrical signal into an induction value. Then, after judging whether the induction value is within a certain group of value intervals among multiple groups of value intervals, it controls the start and stop of the driving member 13, thereby adjusting the position of the limiting member 12 on the base 5 to realize the adjustment of the water outlet angle of the water spraying part 9, where the multiple groups of value intervals are divided according to the wind speed at the construction site.

[0042] The initial position of the limiting member 12 is located at the maximum value of the stroke of the driving member 13. Set the wind speed as X. If the wind speed is in the interval of the minimum value, for example, 0 ≤ X < N (N is any value representing the wind speed, N > 0), at this time, the driving member 13 is at the maximum limit of the stroke, and at this time, the water spraying part 9 sprays water horizontally. When the signal transmitted by the wind speed sensor 11 causes the controller 14 to judge that the wind speed is in the value interval adjacent to 0 at this time, for example, N ≤ X < M (M is also any value representing the wind speed, and M > N), then the driving member 13 will cause the limiting member 12 to move a preset distance away from the connecting part 8. At this time, the included angle between the water spraying part 9 and the connecting part 8 increases, and the water outlet position of the water spraying part 9 is higher than the water outlet position when the wind speed is 0; when the wind speed changes from any value interval to another value interval, the controller 14 will control the driving member 13 to move the limiting member 12 to the position corresponding to this value interval, which enables the water spraying angle of the water spraying part 9 to change with the wind speed.

[0043] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
