Description

Technical Field

[0001] The invention belongs to the technical field of road construction, and in particular relates to dust reduction equipment for pipeline trench operations and a use method thereof. Background Art

[0002] Pipelines cover multiple areas such as water supply, drainage, natural gas, cables and optical fibers, and are crucial to maintaining the normal operation of urban infrastructure.

[0003] This type of pipeline trenching work often occurs on narrow roads between residential areas. However, a large amount of dust is generated during the trenching process, which not only threatens the health of construction workers and reduces air quality, but also brings inconvenience to the lives of nearby residents. It is worth noting that the warning tape poles and warning tapes currently in use do not have the function of dust reduction or dust removal. In order to reduce the impact of dust, special dust reduction and dust removal equipment needs to be introduced. However, doing so may further compress the available passage space, thereby exacerbating the problem of traffic restrictions and causing greater trouble to the daily lives of local residents. Moreover, the warning tape poles have poor anti-lodging performance and are easily affected by wind or other external forces, which may cause the safety protection of the construction area to fail.

[0004] In addition, this type of pipeline trenching operation generally adopts a segmented construction method to minimize the impact on road traffic. The advantage of segmented construction is that each section can be advanced independently, which not only reduces waiting time, but also reduces the interdependence between different construction sections, thereby effectively shortening the construction period of the entire project. However, an obvious disadvantage of this method is that it requires all equipment to be moved frequently between different construction sections. Especially when warning tape poles, warning tapes, and dust reduction and dust removal equipment are used at the same time, the labor cost and time cost required for frequent relocation will increase significantly. Especially for those dust reduction and dust removal equipment that are large in size and heavy in weight, frequent relocation will not only consume a lot of resources, but also slow down the overall progress of construction.

[0005] In summary, the existing technology has the following problems when dealing with pipeline trench operations: a large amount of dust will be generated during trench excavation, and the commonly used warning tape poles and warning tapes do not have dust reduction or dust removal functions. If warning tapes and dust reduction equipment are used at the same time, the passage space will be further compressed, aggravating traffic congestion and affecting residents' lives. In addition, although segmented construction can reduce the impact on road traffic, frequent equipment movement, especially large dust reduction equipment, will increase manpower and time costs, thereby slowing down the construction progress.

[0033] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection and the like commonly used in the prior art, and therefore, it will not be described in detail in this embodiment.

[0034] Embodiment 1

[0035] See also Figure 1 , Figure 2 , Figure 3 , a dust suppression device for pipeline trench operation, the dust suppression device comprises: a base 1, the base 1 has a water storage chamber 11 and a column 12 inside, the water storage chamber 11 is used as a water storage container of the dust suppression device, and the capacity is adjustable to meet different construction requirements. The bottom of the base 1 is provided with a wheeled moving mechanism, which is convenient for the equipment to move between different construction sections and reduce labor costs. The column 12 is provided with a water supply circuit to quickly transport the water in the water storage chamber 11 to the nozzle 22. The column 12 is connected to the upper end of the base 1 and has an installation groove 13 opened to the outside; the pole 2, the pole 2 is composed of a chassis 21 and a nozzle 22 arranged on the chassis 21, the chassis 21 is arranged on the installation groove 13, and a nozzle 23 distributed longitudinally is provided on one side of the nozzle 22, and water mist is sprayed through the water supply circuit to realize the dust suppression function; the nozzle 22 and the water supply circuit are connected to realize the dust suppression operation of the dust suppression device in the pipeline trench operation.

[0036] See also Figure 6 , Figure 7 , Figure 8The chassis 21 has an installation cavity 211 inside, and the installation cavity 211 has a water inlet 212 and a water outlet 213. A blade wheel 25 is rotatably arranged in the installation cavity 211. After the water flows into the installation cavity 211, the blade wheel 25 is driven to rotate. The center of rotation of the blade wheel 25 is connected to the nozzle 22. The water supply circuit is connected to the water inlet 212, so that the blade wheel 25 drives the nozzle 22 to rotate. When the water flows through, the blade wheel 25 rotates to drive the nozzle 22 to rotate, thereby expanding the dust reduction range. The center of rotation of the blade wheel 25 is provided with a connection port 251, and the connection port 251 is connected to the nozzle 22 and rotatably connected to the water supply circuit, so that the nozzle 22 rotates when spraying dust reduction, so as to expand the dust reduction operation range of the dust reduction equipment; ensure that the water flow can be transported to the nozzle 22 through the connection port 251 while driving the blade wheel 25 to rotate, and then spray water mist from the nozzle 23 to reduce dust. The water flow drives the blade wheel 25 to rotate, and the nozzle 22 rotates accordingly, which expands the operating range of dust reduction, improves the dust reduction efficiency, innovatively combines dust reduction with rotary spraying, and enhances the practicability of the equipment.

[0037] Specifically, when the water supply circuit introduces water flow into the installation cavity 211 and enters through the water inlet 212, the impact force of the water flow causes the impeller 25 in the installation cavity 211 to start rotating. As the impeller 25 rotates, the nozzle 22 connected to the impeller 25 also rotates. The rotation of the nozzle 22 allows the nozzle 23 to cover a wider range of dust reduction. Since the nozzle 23 is distributed longitudinally along the nozzle 22, the water mist sprayed during rotation can achieve 360-degree coverage, which is suitable for dust reduction needs in larger areas. This design effectively improves the efficiency of the dust reduction equipment, especially in a longer trench working environment, and can reduce the frequency of equipment movement. The connection port 251 provided at the center of rotation of the impeller ensures that the water flow can be continuously delivered to the nozzle 22 through the connection port 251 while the impeller 25 rotates, without interrupting the water flow. This design not only maintains continuous spraying, but also ensures the stability of the nozzle 22 during rotation and the fluidity of the water flow. Since the nozzle 22 is driven by the rotation of the blade wheel 25, the rotating nozzle 22 can cover the area that is difficult to cover with the fixed nozzle 23, thereby greatly expanding the operating range of the dust reduction equipment. Compared with the traditional fixed nozzle 22 design, this rotary spraying not only covers a wider area, but also reduces dead angles and improves the dust reduction effect.

Specifically, the snap connection design of the upright 2 and the base 1 makes the assembly and disassembly of the equipment simpler and more convenient, greatly reduces the operation time of the construction personnel, and improves the mobility and installation efficiency of the equipment. The ejection spring 133 provides elastic force for the block 132 to stably combine with the slot 214. The control rod 134 on the chassis 21 can be used to easily separate the base 1 from the upright 2, making it easier to disassemble, assemble and move the device.

[0042] Second circuit 16: A water inlet interface and a water outlet interface are provided on the side wall of the installation groove 13, and the water inlet interface and the water outlet interface on the installation groove 13 are respectively connected to the water inlet 212 and the water outlet 213 on the installation cavity 211, and the water inlet interface and the water outlet interface are both connected to the water storage cavity 11; the water delivery circuit includes a second circuit 16, and the second circuit 16 is a circuit connected to the installation cavity 211, and the water outlet end of the second circuit 16 is connected to the water inlet interface.

[0046] Embodiment 2

[0047] This embodiment relates to a dust suppression device for pipeline trench operations. Compared with the dust suppression device in the first embodiment, this embodiment adds a baffle 24 on the vertical pole 2; the details are as follows:

[0048] See also Figure 1 , Figure 6, the upright pole 2 is composed of a chassis 21 and a nozzle 22 arranged on the chassis 21, and a baffle 24 is also arranged on the chassis 21, and the baffle 24 is arranged in a semicircular arc shape. The upright pole 2 is still composed of a chassis 21 and a nozzle 22, but a baffle 24 is added on the basis of the nozzle 22. The baffle 24 is arranged at the upper part of the chassis 21, close to the nozzle 22. The baffle 24 is designed in a semicircular arc shape, and the shape of the semicircular arc can effectively cover part of the spraying area of ​​the nozzle 22. The semicircular arc design ensures that the baffle 24 can better adapt to the construction environment, neither hindering the effective range of dust reduction operations, but also accurately blocking unnecessary spraying ranges. When the equipment is used in trench construction, the main function of the baffle 24 is to separate the construction area from the normal road area. Since the nozzle 22 will rotate and spray water mist during dust reduction, the addition of the baffle 24 can prevent the water mist from spreading to the normal road area where dust reduction is not required, and prevent the impact on road vehicles and pedestrians.

[0049] Embodiment 3

[0050] This embodiment relates to a dust suppression device for pipeline trench operations. Compared with the dust suppression devices in Embodiment 1 and Embodiment 2, this embodiment optimizes the structural arrangement of the connection port 251 and the connection head 124; specifically, as follows:

[0051] The ports of the connection port 251 and the connector 124 are both arranged in a semicircular shape, and the semicircular ports of the connection port 251 and the connector 124 are arranged on the same side as the nozzle 23, and the ports of the connection port 251 and the connector 124 are optimized from the traditional circular structure to a semicircular structure. The design of the semicircular structure is not only more in line with the rotation mode of the nozzle 22 in terms of physical form, but also can control the water flow more efficiently. The key function of the semicircular port is that when the nozzle 22 rotates to a certain angle, the water flow can be automatically cut off. Specifically, the semicircular ports of the connection port 251 and the connector 124 are arranged on the same side of the nozzle 23, so that when the nozzle 23 rotates to face the baffle 24, the water flow will automatically stop flowing to the nozzle 22. Let the nozzle 22 cut off the water flow to the nozzle 22 when the nozzle 23 is rotated to face the baffle 24. The equipment can intelligently control the water flow according to the rotation direction of the nozzle 22 to ensure that the spraying operation is only carried out in the area where dust reduction is required. When the nozzle 22 rotates to the side of the baffle 24, the dust reduction operation will automatically stop to avoid affecting the area where dust reduction is not required. Compared with the dust reduction equipment of Example 1 and Example 2, it is usually impossible to accurately control the spraying area, especially during the rotation of the nozzle 23, the water flow is continuous, which may cause part of the water mist to be sprayed to the area where dust reduction is not required, wasting water resources and affecting the area outside the construction. The optimized design of this embodiment realizes intelligent control of the water flow when the nozzle 22 rotates through the linkage of the semicircular port, thereby avoiding these problems.

[0052] Embodiment 4

[0053] A method for using a dust suppression device for pipeline trench operations, the method for using the dust suppression device for pipeline trench operations described in Embodiments 1 to 3, the method for using comprising:

[0054] The first circuit 15 is switched by the solenoid valve to be connected with the second circuit 16, the third circuit 17 and the fourth circuit 18; the first circuit 15 is switched by the solenoid valve to be connected with the second circuit 16, the third circuit 17 and the fourth circuit 18. According to different operation requirements, the solenoid valve can control the water flow through different circuits and perform different functions.

[0055] When the first circuit 15 and the fourth circuit 18 are connected, the water pump controls the deployment and retraction of the side support assembly 3; through the action of the water pump, the water flow pushes the piston inside the device, thereby controlling the deployment or retraction of the side support assembly 3. The deployment of the side support assembly 3 increases the stability of the device, ensuring that the device will not tilt or collapse during operation, especially in an environment with strong winds. The retraction of the side support assembly 3 facilitates the movement and transportation of the device.

[0056] When the first circuit 15 and the third circuit 17 are connected, the nozzle 22 is controlled by the water pump to perform dust reduction operations; after the water flows into the nozzle 22 through the water pump control, the nozzle 23 sprays water mist to cover the construction area for dust reduction; this operation is usually used when local dust reduction is required, the nozzle 22 is fixed and does not rotate, and the water mist only covers a specific area, which is suitable for precise dust reduction operations.

[0057] When the first circuit 15 is connected to the second circuit 16 and the third circuit 17, the water pump controls the nozzle 22 to rotate and perform dust reduction operations; the water flow not only enters the nozzle 22 for spraying, but also enters the blade wheel 25 mechanism to drive the nozzle 22 to rotate; through the action of the water pump, the water flow drives the blade wheel 25 to rotate, so that the nozzle 22 performs dust reduction operations at different angles, expanding the dust reduction coverage; this mode is suitable for large-area dust reduction, and the nozzle 22 can rotate to ensure uniform dust reduction in the entire construction area and improve work efficiency.

[0058] In addition, as common knowledge in the industry, the water pump and solenoid valve mentioned above are common knowledge, so their principles and structures will not be described in detail.

[0059] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations.
