Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a dust suppression device for building construction. Background Art

[0002] With the rapid development of urban construction, the dust pollution problem generated at construction sites is becoming increasingly serious. These dusts not only threaten the health of construction workers, but also have a serious impact on the surrounding environment and air quality. In order to effectively control and reduce dust pollution in construction, the existing dust reduction technology mainly uses fog cannons to spray water to reduce dust. However, traditional fog cannons have many limitations in practical applications and cannot fully meet the dust reduction needs of construction sites.

[0003] The water spraying volume of the fog cannon truck is usually large. The fog cannon truck usually uses a high-pressure water pump to atomize the water and spray it out to form a large area of ​​water mist. In addition, the fog cannon truck usually adopts a fixed nozzle design, and its spraying range and angle are relatively fixed. This design makes it difficult for the fog cannon truck to adapt to the dust reduction needs of different construction sites. In some specific construction areas, such as the flanks of buildings or narrow construction passages, the fog cannon truck often cannot effectively cover, resulting in poor dust reduction effects.

[0004] The patent with application number "CN202321490646.3" discloses: "An energy-saving and environmentally friendly dust reduction device for construction, including a cart and a dust suction mechanism; by driving the exhaust fan, the exhaust fan will extract the air in the accommodating chamber to form a negative pressure in the accommodating chamber, and the dust suction nozzle will suck the surrounding dusty air into the accommodating chamber, and the water level in the accommodating chamber is higher than the partition, and the dusty air weighs less than the water, so the dusty air will first be filtered out of the air by the water in the accommodating chamber to form sewage, and the filtered air will be sucked out of the box by the exhaust fan;" This application achieves the effect of local dust reduction in construction to a certain extent without producing mud.

[0005] However, the construction site is an open space, and it is difficult to suck away all the dust through the negative pressure of the containing chamber. When a lot of dust is generated, a single vacuum nozzle cannot suck away all the dust, and some dust problems will still exist. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a dust suppression device for construction. Through this design, the problem that the existing fog cannon vehicle has a single operating direction of the nozzle, and the spraying range and angle are relatively fixed and difficult to adapt to the requirements of different construction sites during operation is effectively solved. In addition, the fog cannon vehicle has a large amount of water sprayed. For a small space, the water spray is too concentrated to easily form mud, which affects the construction of workers.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the utility model includes a mobile platform, the mobile platform is fixedly connected to a base, the base is rotatably connected to a bracket, one side of the bracket is fixedly connected to a three-way joint, the three-way joint is fixedly connected to a first water inlet pipe and a second water inlet pipe, the other end of the first water inlet pipe is fixedly connected to a fog cannon barrel, and the other end of the second water inlet pipe is fixedly connected to an auxiliary dust removal frame;

[0008] The auxiliary dust removal frame comprises a support base, the support base is fixedly connected to the bracket, a rotary joint is rotatably connected to the support base, and an atomizing nozzle is fixedly connected to the rotary joint.

[0009] Preferably, a slide groove is provided on the support seat, the slide groove is slidably connected to a fixing seat, the fixing seat is fixedly connected to the bracket, and the support seat and the fixing seat are fixedly connected by bolts.

[0010] Preferably, a control valve is fixedly connected to the rotary joint, one end of the control valve is connected to a bellows, and the other end of the bellows is fixedly connected to the atomizing nozzle.

[0011] Preferably, two symmetrically distributed support rods are fixedly connected to the bracket, the other ends of the support rods are hinged to the fog cannon barrel, the two support rods are located on both sides of the fog cannon barrel, and a hydraulic rod is hinged on the fog cannon barrel, and the other end of the hydraulic rod is hinged to the bracket.

[0012] Preferably, an anti-collision frame is fixedly connected to the bracket, and the anti-collision frame is located on the side of the fog cannon barrel.

[0013] Preferably, the mobile platform includes a carrier plate, a first support rod is fixedly connected to the carrier plate, one end of the first support rod is rotatably connected to a first caster, the other end of the first support rod is hinged to a second support rod, and the lower end of the second support rod is rotatably connected to two symmetrically distributed second casters.

At the same time, the atomizing nozzle can be adjusted 360 degrees in direction under the action of the rotating joint, and has strong applicability. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Example 1

[0024] Please see attached Figure 1-5 , this embodiment is a dust suppression device for construction: it includes a mobile platform 1, the mobile platform 1 is fixedly connected to a base 2, the base 2 is rotatably connected to a bracket 3, one side of the bracket 3 is fixedly connected to a three-way joint 4, the three-way joint 4 is fixedly connected to a first water inlet pipe 5 and a second water inlet pipe 6, the other end of the first water inlet pipe 5 is fixedly connected to a fog cannon barrel 7, the other end of the second water inlet pipe 6 is fixedly connected to an auxiliary dust removal frame 8; the auxiliary dust removal frame 8 includes a support seat 801, the support seat 801 is fixedly connected to the bracket 3, the support seat 801 is rotatably connected to a rotary joint 802, and the rotary joint 802 is fixedly connected to an atomizing nozzle 803.

[0025] The mobile platform 1 is located at the lowermost position of the device, the base 2 is fixed on the mobile platform 1, and the bracket 3 is rotatably connected to the base 2. The operating position of the fog cannon barrel 7 and the unassisted dust reduction frame on the bracket 3 can be adjusted by rotating the bracket 3, so that the fog cannon barrel 7 and the auxiliary dust reduction frame can be adjusted 360 degrees, thereby increasing the operating range and application range of the device. The fog cannon barrel 7 is externally connected to a first water inlet pipe 5, and the dust reduction auxiliary frame is externally connected to a second water inlet pipe 6. The first water inlet pipe 5 and the second water inlet pipe 6 are connected through a joint, and the water inlet pipe of the three-way joint 4 is externally connected to a water tank. A high-pressure pump, a fan and a control device are also arranged in the fog cannon barrel 7. The fog cannon barrel 7 is based on the air supply principle. A high-pressure pump and a fine atomizing nozzle are used to atomize water, and then the air volume and pressure of the fan are used to transmit the atomized water mist to a long distance, so that the water mist can reach a long distance. The fog cannon barrel 7 has the same atomization principle as the existing fog cannon vehicle, and no excessive description is made here. The auxiliary dust removal frame 8 is fixed to the front side of the bracket 3 through the support seat 801, and the atomizing nozzle 803 of the auxiliary dust removal frame 8 faces the side of the bracket 3. The atomizing nozzle 803 can be rotated relative to the support seat 801, and the atomizing nozzle 803 performs a small range of spraying on the side wings of the bracket 3, assisting the fog cannon barrel 7, increasing the range of dust removal, and improving the dust removal effect of the device.

[0026] A slide groove 804 is provided at the bottom of the support seat 801. Under the action of the slide groove 804, the support seat 801 can slide left and right relative to the fixed seat 805, so as to adjust the position of the support seat 801 on the bracket 3. The support seat 801 and the fixed seat 805 are fixed by screws and nuts for easy disassembly and assembly.

[0027] There are three groups of atomizing nozzles 803, and each of the three groups of atomizing nozzles 803 is provided with a control valve 806. When in use, a corresponding number of atomizing nozzles 803 can be opened as needed, thereby achieving the dust reduction effect while avoiding the waste of water resources. The bellows 807 has good deformation ability, and the position of the atomizing nozzle 803 can be adjusted at will, so that the atomizing nozzle 803 better corresponds to the dust reduction point.

[0028] Furthermore, in order to facilitate the adjustment of the range of action of the fog cannon barrel 7, an oil pump is also provided on the bracket 3. The oil pump controls the extension and retraction of the hydraulic rod 10. The hydraulic rod 10 is located on the front side of the support rod 9. When the hydraulic rod 10 is extended, the hydraulic rod 10 drives the front side of the fog cannon barrel 7 to rotate upward, thereby raising the elevation angle of the fog cannon barrel 7, and the highest point of the parabola sprayed by the fog cannon barrel 7 becomes higher, and the spraying distance becomes relatively larger. On the contrary, when the hydraulic rod 10 contracts, the elevation angle of the fog cannon barrel 7 is relatively reduced.

[0029] Anti-collision frames 11 are provided on both sides of the fog cannon barrel 7. The anti-collision frames 11 can rotate synchronously with the fog cannon barrel 7. When rotating, the anti-collision frames 11 protect the fog cannon barrel 7 to avoid direct collision with the fog cannon barrel 7 in a cluttered environment, thereby ensuring the safety of the fog cannon barrel 7. Example 2

[0030] The structure is the same as that of the listed embodiment, such as Figure 3 As shown, the specific similarities of this embodiment are: the mobile platform 1 includes a carrier plate 101, a first support rod 102 is fixedly connected to the carrier plate 101, one end of the first support rod 102 is rotatably connected to a first caster 103, the other end of the first support rod 102 is hinged to a second support rod 104, and the lower end of the second support rod 104 is rotatably connected to two symmetrically distributed second casters 105.

[0031] Due to the harsh environment in which buildings are used, the road surface at the construction site is uneven, and it is troublesome to move and fix the device at the site of use. Two first casters 103 and four second casters 105 are provided under the mobile platform 1. The first casters 103 and the second casters 105 are symmetrically distributed. The first caster 103 is installed on the first support rod 102. The first support rod 102 is an L-shaped structure and is fixed to the carrier plate 101 by two connecting pins. The middle part of the second support rod 104 is rotatably connected with the connecting pin. The second support rod 104 is an N-shaped structure. The two second casters 105 are located at the lower side of the second support rod 104. When encountering an uneven road surface, the second support rod 104 will rotate, thereby changing the height of the second caster 105 from the ground, which facilitates the movement of the device.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
