Description

Technical Field

[0001] This utility model relates to a spraying device, specifically a dust control and noise reduction spraying device, belonging to the technical field of dust control and noise reduction measures in building engineering. Background Technology

[0002] To ensure the cleanliness of construction sites, dust control measures are required for areas and equipment prone to dust generation. Existing construction projects emphasize the use of dust suppression spraying devices, which typically involve installing numerous spray nozzles on the perimeter fences. However, commonly used spray nozzles are difficult to rotate or adjust manually, and they are not convenient for increasing the dust suppression range, thus reducing the practicality of dust suppression spraying devices at construction sites.

[0003] Currently, Chinese utility model patent CN212188325U discloses a dust suppression spraying device for construction engineering, including a base plate. A water tank is installed at the rear end of the top surface of the base plate. A water pump connected to the inner cavity of the water tank is installed at the bottom end of the front side wall of the water tank. The outlet end of the water pump is connected to a water outlet pipe. Support rods are installed at the left and right corners of the front end of the top surface of the base plate. Fixing screw holes are opened on the rear side wall of the support rods. Mounting blocks are set on the rear side wall of the support rods. Auxiliary blocks that abut against the rear side wall of the support rods are fixed on the upper and lower end faces of the mounting blocks. Fixing bolts with screw-fitted ends to the fixing screw holes are inserted into the auxiliary blocks. A staggered insertion hole extending to the right side wall of the mounting block is opened on the left side wall of the mounting block. A transition pipe is set between the mounting blocks. Connecting blocks are fixed at both ends of the transition pipe. Due to the varying construction sites and areas, most dust suppression spraying devices used in construction projects require manual handling and movement during the spraying process when spraying from the direction of pollution sources. This is time-consuming, labor-intensive, and affects spraying efficiency, making it generally inconvenient.

[0135] In summary, a more specific embodiment of this utility model is as follows:

[0136] Before using the dust and noise reduction spraying device with the above-mentioned design structure, simply transport the assembled spraying device to the designated work site by manual labor or with appropriate equipment.

[0137] Before use, the operator installs the support frame 1 of this device at or near the center of the pollution source, then installs and connects each component, and then the operator debugs and checks whether the connection between each component is secure and whether the control connection mode can operate normally. Finally, after initially adjusting the spraying area of ​​the nozzle 7, it can be put into use.

[0138] When using it, the operator should first ensure that the water in the water storage tank 21 overflows the water pump inlet to reach a reasonable water usage range. At the same time, the water supply pipe 23 is connected to the external water supply pipe to supply water, so as to ensure that there is enough water for use.

[0139] Then, the operator turns on the power start / stop button and the water pump start / stop button in sequence through the remote control device 5. The control device 6 then provides power to each component, and the water pump starts to work.

[0140] Next, the operator selects the spraying mode of the nozzle 7 through the remote control device 5. Then, the water source enters the spraying device 4 through the water outlet pipe 22, and then reaches the nozzle 7 to carry out the spraying work.

[0141] Finally, during the spraying process of the nozzle 7, the operator can adjust the horizontal rotation angle and the pitch rotation angle of the spraying device 4 through the remote control device 5 according to the specific usage environment and spraying area to meet different usage scenarios and requirements. Different spraying modes, different horizontal rotation modes or different pitch rotation modes can also be selected for spraying.

[0142] During the above-mentioned use, if it is necessary to adjust the horizontal rotation angle of the spraying equipment 4, the operator can operate it through the corresponding button of the remote control device 5. After the remote control device 5 issues a command, the first wireless remote control receiving module on the horizontal rotation component 42 receives the signal. The first wireless remote control receiving module controls the first motor to start working. The first motor drives the first drive gear to rotate, and then the first drive gear rotates and drives the first driven gear connected to it to rotate. Thus, the first driven gear drives the first inner cylinder connected to it to rotate inside the first outer cylinder. Then, the first inner cylinder drives the first connecting pipe 43, the pitch rotation component 44, the second connecting pipe 45 and the nozzle 7 connected through the elbow pipe to rotate around the water inlet pipe 41 as the center, ultimately satisfying the operator's requirements for adjusting the horizontal rotation angle of the spraying equipment 4.

[0143] When it is necessary to adjust the pitch and rotation angle of the spraying equipment 4, the operator operates it through the corresponding button of the remote control device 5. After the remote control device 5 issues a command, the second wireless remote control receiver module on the pitch and rotation assembly 44 receives the signal and controls the second motor to start working. The second motor drives the second drive gear to rotate, and then the rotation of the second drive gear drives the second driven gear connected to it to rotate. In turn, the second driven gear drives the second inner cylinder connected to it to rotate inside the second outer cylinder. Then, the second inner cylinder drives the nozzle 7 connected to the second connecting pipe 45 to rotate, ultimately satisfying the operator's requirements for adjusting the pitch and rotation angle of the spraying equipment 4.

[0144] In summary, the specific principles of the existing structure are as follows:

[0145] The remote control device 5 is also an existing product that can be purchased on the market. It is used in this utility model to complete the corresponding operation and realize the corresponding dust control work on the construction section of the construction site.

[0146] 1. The water mist mode can achieve a certain amount of sound wave blocking, that is, to achieve noise reduction.

[0147] The specific signal control process is briefly described below:

[0148] The wireless remote control receiver module uses existing technology and equipment for connection. During pairing, ensuring the address code matches the receiving IC, the oscillation resistor matches, and the frequency is consistent is sufficient to remotely control the device. A Siemens S7-200smart PLC is used at the device end to control each device. The control flow is as follows: Remote control device 5 sends a communication signal, which is converted by the remote control conversion terminal into a signal that the PLC can recognize, thereby controlling each workflow.

[0149] The following is an explanation of the basic principles of PLC-controlled equipment:

[0150] By inputting signals through remote control device 5, the PLC controller of control device 6 can process the signals and directly control the power supply, horizontal rotation component 42, pitch rotation component 44, and nozzle 7 of control device 6 to start or stop working, thereby achieving the purpose of remote control.
