[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] See also Figures 1 to 8 As shown;

[0038] The dust suppression device for the body of an unmanned mining truck of this embodiment is integrated in the body of the unmanned mining truck, and the dust suppression device includes:

[0039] A dust detection module 1 integrated in the compartment; and

[0040] A plurality of spray heads 2 are arranged inside and outside the compartment, and the spray heads 2 are connected to the motor pump group 3 in the compartment through a spray pipe, and the motor pump group 3 transports the spray liquid in the water tank 4 or the chemical agent tank 5 in the compartment to the corresponding spray heads 2;

[0041] The dust suppression device also includes:

[0042] The control unit 6 is connected to the remote monitoring center through a communication interface to exchange data, and uploads the system status after receiving remote instructions.

[0043] Specifically, the present embodiment discloses a dust suppression device suitable for an unmanned mining truck body, which includes a control unit 6, a dust detection module 1 and a spray system; the dust detection module 1 of the present embodiment is installed at different positions of the body to monitor the dust concentration in real time, and the control unit 6 is connected to the dust detection module 1 to receive dust concentration data and make processing decisions. The spray system of the present embodiment has a plurality of spray heads 2 arranged on the inside and outside of the top of the body, and the spray heads 2 receive the spray liquid delivered by the motor pump group 3 and spray water mist or chemical dust suppressant according to the instructions of the control unit 6.

[0044] Preferably, the spray pipe of this embodiment is arranged at the upper end of the box body, and a plurality of spray heads 2 are arranged on the spray pipe at intervals, and the maximum spray widths of adjacent spray heads 2 partially overlap.

[0045] The spray heads 2 located inside the compartment and the spray heads located outside the compartment are arranged alternately;

[0046] The spray head 2 located inside the carriage acts on the dust generated inside the carriage due to material crushing, bumping and wind action;

[0047] The spray head 2 located outside the vehicle body acts on the dust raised during the travel of the mining truck.

[0048] More preferably, the maximum spray widths of adjacent spray heads 2 of this embodiment overlap each other by 1 / 3-1 / 4; according to the selection theory, the maximum spray width of the spray head 2 of this embodiment is 255mm; the installation distance E of adjacent spray heads 2 is 170mm-191mm; the angle between the fan surface of the spray head 2 and the axis of the spray pipe is 5°-15°.

[0049] The motor pump group 3 of the present embodiment is a combination of a motor and a water pump, which provides pressure for the spray head 2 to achieve a spray effect. The spray heads 2 are distributed on the left and right sides of the compartment and the front top of the compartment, and the spray heads 2 on the left and right sides are arranged in a staggered manner. The spray angle of the spray head 2 is selected as the theoretical value of the coverage range of the spray head 2, which is calculated based on the angle of the spray head 2 and the distance from the nozzle under the premise that the spray angle remains unchanged within the entire spray distance range. The arrangement of the spray heads 2 of the present embodiment is as follows: the fan-shaped spray head 2 is a shape with gradually tapering edges. By utilizing this characteristic, the fan-shaped edges of adjacent spray heads 2 are reasonably superimposed and arranged, and the uniform effect of the end face of the entire spray line can be obtained. Half requires that the maximum spray width W of the spray head 2 should overlap each other by 1 / 3-1 / 4.

[0050] Arrangement of spray head 2: spray head 2 requires that the spray fan shape must be uniform under the specified spray angle and nozzle pressure, otherwise the fan atomization effect cannot be achieved. Too high or too low pressure will affect the spray fan shape and effect. The flow rate at spray head 2 is determined by the nozzle pressure, which increases with the increase of nozzle pressure. The relationship between flow rate and pressure is:

[0051]

[0052] Where Q is flow rate and P is pressure.

[0053] High-pressure water pump selection: Set the water pump working pressure to 7MP a , then the water pump power calculation formula is:

[0054]

[0055] Wherein, N is the pump power, kW; P is the pump pressure, 10MPa; Q is the spray boom flow rate, η is the mechanical efficiency, and η=85%.

[0056] Preferably, the dust detection module 1 of this embodiment includes a plurality of dust sensors distributed at different positions of the compartment; the dust sensors monitor the dust concentration in the air in real time and transmit the data to the control unit 6 .

[0057] The dust detection module 1 of this embodiment continuously detects the dust concentration inside and outside the vehicle compartment and transmits the data to the control unit 6; the dust detection module 1, such as GP2Y1014AU0F, is mainly composed of an infrared light emitting diode and a phototransistor, which are arranged diagonally, allowing the device to detect the reflected light of dust in the air. When dust particles in the air pass through the inside of the sensor, they scatter the light emitted by the infrared light emitting diode. This scattered light is then detected by the phototransistor. The intensity of the detected scattered light is proportional to the dust concentration in the air, allowing the system to evaluate the relative concentration of dust.

[0058] The dust detection method for the GP2Y1014AU0F dust detection module 1 can be controlled according to the principle of its electronic discrimination control program. Its detection principle and method do not belong to the scope of this utility model. Here, only the output program control is performed based on its detection and judgment results. The control of the output program is based on the voltage change of the GP2Y1014AU0F dust detection module 1. Its output program is controlled according to the following voltage changes:

[0059] Detectable range (output voltage variable range (V)) = output voltage range: VoH (V) - dust-free output voltage: Voc (V).

[0060] Dust concentration: Detectable dust concentration range (mg / m 3 )=Detection range (output voltage variable range (V))÷Detection sensitivity: K(V / (0.1mg / m 3 ).

[0061] The control unit 6 of this embodiment intelligently formulates a spray strategy based on dust concentration and distribution, as well as meteorological monitoring data, and uses dust sensors distributed at key locations in the car to detect dust concentration in the air in real time. These sensors can capture small changes in dust concentration and immediately transmit data to the control unit 6.

[0062] After receiving the data, the control unit 6 analyzes the dust concentration and distribution through a preset algorithm to determine whether the spray dust suppression device needs to be started or adjusted. The spray dust suppression system supports multiple control modes, including timing, quantitative, etc. These modes can be combined according to actual needs to adapt to different working environments and requirements. According to the strategy, the control unit 6 sends a specific working instruction to the spray dust suppression device, opens the spray head 2 at the corresponding position, and starts the motor to drive the water pump to work.

[0063] The motor and the water pump form a motor pump unit 3, which provides pressure for the spray head 2 to achieve a spraying effect.

[0064] In the above technical solution, the utility model provides a dust reduction device for a cabin of an unmanned mining truck, which has the following beneficial effects:

[0065] The dust reduction device of the utility model realizes real-time monitoring and precise spraying of dust through intelligent sensing and control technology, greatly improving the dust reduction efficiency; the system automatically adjusts the water consumption and chemical agent usage according to actual needs, maximally saving resources and reducing the pollution of dust to the environment.

[0066] The dust suppression device of the utility model can intelligently adjust the spray strategy according to environmental changes and dust conditions, with fast response and flexible operation; the device effectively reduces the potential harm of dust to mining trucks and mining equipment, and reduces maintenance costs.

[0067] The dust suppression device of the utility model reduces the health risks of mine workers and improves the overall working environment quality of the mining area.

[0068] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
