Description

Technical Field

[0001] This utility model relates to the field of construction dust suppression technology, and in particular to a dust suppression device for use at building construction sites. Background Technology

[0002] During the construction of buildings and municipal engineering projects, a large amount of dust is easily generated during the excavation, stockpiling, loading and unloading of earthwork, and interior and exterior decoration of structures. In order to meet the requirements of civilized and environmentally friendly construction, dust suppression devices are usually installed around the foundation pit or the main structure. These dust suppression devices can reduce the dust around the foundation pit and the outer protective frame.

[0003] Patent CN221601573U discloses a construction dust suppression device. In use, the angle of the spray pipes is first changed by adjusting the components. Rotating the handle at the bottom of the mounting frame drives the lead screw to rotate, and the rack frame slides around the limit rod. Driven by the lead screw, the rack frame moves along the limit rod. The rack frame meshes with two gears, which in turn rotate the two spray pipes within the mounting frame, changing their horizontal angle. Water is then supplied to the water supply pipe, flowing into multiple branch pipes and then through connecting pipes to the spray pipes for spraying. Simultaneously, the motor at the top of the guardrail body is activated, driving the transmission wheel to rotate. The transmission wheel, via belt two, drives the driven wheel connected to it to rotate. The driven wheel, via belt one, drives another driven wheel to rotate. The two branch pipes are also driven to rotate synchronously. The two spray pipes connected to the branch pipes rotate synchronously while spraying water, increasing the spray area and thus enhancing the dust suppression effect. However, the above-mentioned device has the following defects when in use. During the dust suppression process, the spray pipe is close to the belt, and the sprayed water is very likely to fall onto the belt. The belt is in contact with water for a long time and is continuously exposed to the sun, which will significantly accelerate the aging and corrosion and reduce the service life. In addition, there are a lot of dust, sand and other impurities in the construction environment. They adhere to and accumulate on the surface of the belt. This will not only aggravate the wear of the belt when it rubs against the drive wheel and driven wheel, but may even cause damage to the belt surface, such as scratches and cracks, which will further shorten the normal service life of the belt.

[0004] Therefore, how to increase the protection of the transmission structure and extend its service life during dust suppression at construction sites has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The present invention aims to provide a dust suppression device for use at building construction sites to overcome the shortcomings mentioned above.

[0006] To achieve the above objectives, the technical solution of this utility model is: a dust suppression device for building construction sites, comprising:

[0007] The base plate has a water supply pipe installed at its upper end and a dust cover installed at its upper end, with the dust cover installed around the water supply pipe.

[0008] A water inlet pipe, which passes through the dust cover and connects to the water supply pipe;

[0009] A water outlet pipe, which passes through the dust cover and connects to the water supply pipe;

[0010] A branch pipe, which rotates vertically through the dust cover, and its connection to the water supply pipe is rotatably connected.

[0011] The branch pipe is connected to the upper end of the branch pipe, and each branch end is connected to a spray pipe installed horizontally; and

[0012] The first transmission assembly, which is arranged at the upper end of the base plate and located inside the dust cover, is used to drive the branch pipe to rotate.

[0013] Furthermore, the water inlet pipe is connected to a flexible hose, the water inlet pipe and the flexible hose are detachably connected, and the water outlet pipe is detachably connected to a pipe cap.

[0014] Furthermore, the first transmission assembly includes a motor, a first transmission wheel, and a first transmission belt. The motor is mounted on the upper end of the base plate, and the output shaft and branch pipe of the motor are both fixedly connected to the first transmission wheel. The two first transmission wheels are fitted with the same first transmission belt.

[0015] Furthermore, the branch pipe has two connection ports arranged opposite each other, and the two connection ports correspond one-to-one with the two branch pipes and are rotatably connected. A second transmission assembly is arranged between the two branch pipes. The first transmission assembly drives one of the branch pipes to rotate, and then drives the other branch pipe to rotate through the second transmission assembly.

[0016] Furthermore, the second transmission assembly includes a second transmission wheel and a second transmission belt, both branch pipes are fixedly connected to the second transmission wheel, and the two second transmission wheels are fitted with the same second transmission belt.

[0017] Furthermore, a sealing door with a handle is provided on the side of the dust cover away from the water inlet pipe, and a pressure plate clamp is provided on the side wall of the dust cover, the pressure plate of the pressure plate clamp selectively abutting against the side wall of the sealing door.

[0018] Furthermore, the base plate is provided with several card holders, and the water supply pipe is snapped into the groove of the card holder.

[0019] Furthermore, the dust cover has several ventilation holes on its opposite sidewall, and two sets of limiting slide grooves are arranged opposite each other inside the dust cover. The two sets of limiting slide grooves are slidably connected to filter plates, and the filter plates and ventilation holes are arranged opposite each other.

[0020] Furthermore, two fixing plates are arranged opposite each other at the lower end of the base plate. The two fixing plates are used to snap onto the guardrail. One of the fixing plates has several bolts on its side wall. The bolts pass through the two fixing plates and are connected to the nuts.

[0021] Compared with the prior art, this utility model has at least the following advantages: During use, water flows into the water supply pipe through the inlet pipe, and the water supply pipe then distributes the water to the branch pipes. At this time, the first transmission component is activated, driving the branch pipes to rotate vertically. As the branch pipes rotate, the diversion pipes connected to their upper ends also move synchronously. The diversion pipes distribute water to various horizontally positioned spray pipes, which then spray a fine water mist around the perimeter, controlling dust settling at the construction site. Since the construction site is filled with a large amount of dust and gravel, a dust cover plays a crucial role in protecting the transmission structure. It covers the water supply pipe, preventing a large amount of dust and gravel from directly contacting the first transmission component, reducing the accumulation of impurities on the structural surface. Simultaneously, the dust cover prevents the water mist sprayed from the spray pipes from splashing onto the structure, avoiding aging and corrosion caused by prolonged contact with moisture and continuous sun exposure. This extends the service life of the entire transmission structure and ensures the stable and long-term operation of the dust suppression device. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1:

[0032] Reference Figure 1-3 This utility model provides a dust suppression device for building construction sites, comprising:

[0033] The base plate 1, serving as the supporting component of the entire device, has a water supply pipe 2, a crucial channel for water supply to the entire device, installed on its upper end. A dust cover 3 is also installed on the upper end of the base plate 1, positioned around the water supply pipe 2. An inlet pipe 4 passes through the dust cover 3 and connects to the water supply pipe 2. An outlet pipe 5 passes through the dust cover 3 and connects to the water supply pipe 2, with the inlet pipe 4 and outlet pipe 5 on the same side. A branch pipe 6 rotates vertically through the dust cover 3, and its connection port 7 with the water supply pipe 2 is rotatably connected. This branch connection not only ensures… The branch pipe 6 rotates smoothly, and the connection between the branch pipe 6 and the connection port 7 and the connecting pipe has good sealing performance, which can effectively prevent water leakage. The connecting pipe is existing technology and will not be described in detail here. The longitudinal section is a T-shaped diversion pipe 8, which is connected to the upper end of the branch pipe 6. The diversion end is connected to a spray pipe 9 arranged in the horizontal direction. The first transmission assembly is arranged on the upper end of the base plate 1. The first transmission assembly is also located inside the dust cover 3. When the first transmission assembly is started, it drives the branch pipe 6 to rotate.

[0034] Reference Figure 2 The inlet pipe 4 is connected to the hose 10. The inlet pipe 4 and the hose 10 are detachably connected by a clamp. This design greatly facilitates the assembly and disassembly of the device. The outlet pipe 5 is detachably connected to the pipe cover 11 by a threaded connection. When multiple devices need to be installed, the inlet pipe 4 of the first device is connected to an external water source. The inlet pipe 4 and outlet pipe 5 of two adjacent devices are connected by the hose 10 to form a continuous water supply network. The outlet pipe 5 of the last device is sealed with the pipe cover 11 to ensure the closedness of the entire water supply system.

[0035] Reference Figure 3-4 The first transmission assembly includes a motor 12, a first transmission wheel 13, and a first transmission belt 14. The motor 12 is mounted on the upper end of the base plate 1. The output shaft of the motor 12 and the branch pipe 6 are both fixedly connected to the first transmission wheel 13. The two first transmission wheels 13 are fitted with the same first transmission belt 14. When the motor 12 starts, the power is transmitted through the first transmission wheel 13 and the first transmission belt 14, thereby driving the branch pipe 6 to rotate.

[0036] The branch pipe 6 has two connection ports 7, which correspond one-to-one with the two branch pipes 6 and are rotatably connected. The spray pipes 9 on both sides protrude from the base plate 1. A second transmission assembly is arranged between the two branch pipes 6. The first transmission assembly drives one of the branch pipes 6 to rotate, and then drives the other branch pipe 6 to rotate through the second transmission assembly. Under the action of the first transmission assembly and the second transmission assembly, the spraying area of ​​the spray pipe 9 can be increased.

[0037] The second transmission assembly includes a second transmission wheel 15 and a second transmission belt 16. Both branch pipes 6 are fixedly connected to the second transmission wheel 15, and the two second transmission wheels 15 are fitted with the same second transmission belt 16, realizing the synchronous rotation of the two branch pipes 6.

[0038] A sealed door 17 with a handle is provided on the side of the dust cover 3 away from the water inlet pipe 4. The design of the sealed door 17 makes it convenient for staff to open at any time to perform inspection, maintenance and other operations on the internal structure. In order to ensure the stability of the sealed door 17 in the closed state, a pressing clip 18 is provided on the side wall of the dust cover 3. The pressing clip 18 selectively abuts against the side wall of the sealed door 17. The pressing clip 18 is a pressing structure for microscopes.

[0039] The base plate 1 is provided with three card holders 19. The number of card holders 19 is not specifically limited. The card holders 19 are set according to the length of the water supply pipe 2. The water supply pipe 2 is inserted into the groove of the card holder 19. The card holder 19 can ensure that the water supply pipe 2 does not shift during operation.

[0040] The dust cover 3 has several ventilation holes 20 on its opposite sidewall. Inside the dust cover 3, there are two sets of limiting slide grooves 21. The two sets of limiting slide grooves 21 correspond one to one and are slidably connected to a filter plate 22. The filter plate 22 is provided with a limiting protrusion. The limiting protrusion and the limiting slide groove 21 are slidably connected. The filter plate 22 and the ventilation holes 20 are arranged opposite to each other. The filter plate 22 can not only ensure the air circulation inside the dust cover 3, but also filter dust and impurities in the outside air to prevent them from entering the device and affecting the operation of the device.

[0041] In use, the base plate 1 is first placed on the construction site. Workers use heavy objects (stones, bricks, etc.) to press down on the top of the dust cover 3. If multiple devices are set up according to actual needs, the water inlet pipe 4 of the first device is connected to an external water source. The water inlet pipe 4 and water outlet pipe 5 of the adjacent devices are connected in sequence using the hose 10. The water outlet pipe 5 of the last device is sealed with the pipe cap 11. Then the motor 12 is started. The power of the motor 12 is transmitted to the branch pipe 6 through the first transmission wheel 13 and the first transmission belt 14, driving one of the branch pipes 6 to rotate. This branch pipe 6 then drives the other branch pipe 6 to rotate synchronously through the second transmission component.

[0042] As branch pipe 6 rotates, the connected diversion pipe 8 and spray pipe 9 also rotate. Water enters water supply pipe 2 from inlet pipe 4, then flows to branch pipe 6 and diversion pipe 8, and finally sprays out from spray pipe 9 at multiple angles. Combined with the design of dust cover 3, its ventilation holes 20, and filter plate 22, it effectively reduces dust, ensures the cleanliness of the device's interior, and provides protection for the internal structure.

[0043] Example 2:

[0044] Reference Figure 5 The difference between this embodiment and embodiment one is that: two fixing plates 23 are provided opposite to each other at the lower end of the base plate 1. These two fixing plates 23 play a key fixing role. They are used to snap onto the guardrail. Several bolts (not shown in the figure) are provided on the side wall of one of the fixing plates 23. The bolts pass through the two fixing plates 23 and are tightly connected with the nuts 25, further enhancing the stability of the connection between the device and the guardrail.

[0045] In use, the device is attached to the guardrail by the fixing plate 23 at the lower end of the base plate 1, and then the fixing plate 23 and the guardrail are fastened together by bolts and nuts 25.
