[0039] Embodiment 1:

[0040] like Figure 1 and Figure 2 As shown, this embodiment provides a spray dust suppression device for water conservancy projects, including a water supply system and a control system; the water supply system includes a first water supply main pipeline 2, a second water supply main pipeline 4, a plurality of water supply branch pipelines 6, a filter 1, a water pump 3, a first signal control valve 5 and a plurality of spray heads 7; the filter 1 is arranged at the water inlet of the first water supply main pipeline 2, and the water outlet of the first water supply main pipeline 2 is connected to the water inlet of the second water supply main pipeline 4 through the water pump 3; the second water supply main pipeline 4 is provided with a water outlet matching the plurality of water supply branch pipelines 6 to communicate with each water supply branch pipeline 6; the first signal control valve 5 is installed on the second water supply main pipeline 4; a plurality of spray heads 7 are installed at the ends of the plurality of water supply branch pipelines 6, and the number of the spray heads 7 is the same as the number of the water supply branch pipelines 6.

[0041] The control system includes a plurality of dust detectors 12 for detecting dust parameters in the surrounding air and an intelligent controller 11, wherein the plurality of dust detectors 12 can be installed at each sprinkler head 7, for example, to detect dust parameters in the environment where each sprinkler head 7 is located. It should be noted that the installation positions of the plurality of dust detectors 12 are not fixed, and can be installed at different positions according to actual needs.

[0042] The intelligent controller 11 includes a single chip computer 11 - 1 and a display module 11 - 2 .

[0043] The intelligent controller 11 is connected to multiple dust detectors 12, which is essentially a single chip microcomputer 11-1 (e.g., 89C51 series single chip microcomputer) of the intelligent controller 11 connected to multiple dust detectors 12, so as to obtain dust parameters detected by multiple dust detectors 12, and display the obtained dust parameters through a display module 11-2, such as a touch screen. The dust parameters include dust concentration and dust particle size.

[0044] Before use, the end of the first water supply main pipe provided with the filter is placed in a water storage tank or connected to a water supply system.

[0045] When in use, the staff turns on the water pump to pump water according to the dust parameters displayed on the display module or inputs a signal to turn on the water pump to the single-chip microcomputer through the touch display screen. The single-chip microcomputer controls the opening of the water pump to pump water. When pumping water, the water is first filtered through the filter and then enters the first water supply main pipeline to filter out large particles of pollutants in the water, thereby effectively avoiding blockage of the water supply pipeline and ensuring the timeliness of spraying.

[0046] Then, the opening of the first regulating signal control valve is adjusted, or the opening signal of the regulating signal control valve is input to the single-chip microcomputer through the touch display screen. The single-chip microcomputer adjusts the opening of the first signal control valve according to the received opening signal, so that water flows from the first water supply main pipeline through the second water supply main pipeline, and is sprayed out by the sprinkler head of the water supply pipeline to spray the dust in the environment.

[0047] In addition, the threshold range of detected dust parameters can be pre-set through the touch screen to turn on the water pump and adjust the opening of the signal control valve. For example, when the dust concentration is pre-set to be below 10 mg / m3, the water pump will not be turned on or off. When the dust concentration is between 10 and 20 mg / m3, the water pump will be turned on and the opening of the signal control valve will be adjusted to 45 degrees; when the dust concentration is above 20 mg / m3, the water pump will be turned on and the opening of the signal control valve will be adjusted to 90 degrees.

[0048] This embodiment enables spraying to be turned on or off according to the dust conditions in the surrounding environment, thereby helping to save water resources and enabling spraying to be performed in a timely manner.

[0049] Embodiment 2:

[0050] like Figure 3 and Figure 4 As shown, another embodiment of a spray dust suppression device for water conservancy projects is provided:

[0051] The control system also includes a wireless handheld terminal 14; the intelligent controller 11 also includes a wireless communication module 11-3 and an alarm module 11-4.

[0052] A second signal control valve 10 is provided on each of the plurality of water supply pipelines 6; the intelligent controller 11 is connected to the second signal control valve 10 to control the opening of the second signal control valve 10. When in use, the opening of the second signal control valve 10 on the corresponding water supply pipeline 6 is controlled according to the dust parameters detected by the plurality of dust detectors 12 at different positions displayed on the display module 11-2.

[0053] For example, there are three water supply pipelines, and dust detectors are provided at the sprinkler heads at the ends of the three water supply pipelines. For the convenience of explanation, the second signal control valves on the three water supply pipelines are respectively marked as the second signal control valve A, the second signal control valve B and the third signal control valve C; the dust detectors at the three sprinkler heads are respectively marked as dust detector A, dust detector B and dust detector C. If the dust concentration detected by the dust detector A displayed on the display module is less than 5 mg / m3, and the dust concentrations detected by the dust detectors B and C are both greater than 20 mg / m3, the opening degree of the second signal control valve A is adjusted to 0 degrees, and the opening degrees of the second signal control valve B and the second signal control valve C are adjusted to 90 degrees.

[0054] It should be noted that the opening degree of the second signal control valve can be set according to actual conditions.

[0055] The device also includes a water depth detector 15; the water depth detector 15 is installed at the water inlet of the first water supply main pipe 2 to measure the water depth when the device is placed in the water tank to draw water; the water depth detector 15 is communicatively connected to the intelligent controller 11. In fact, the water depth detector 15 is connected to the single-chip microcomputer 11-1 of the intelligent controller 11. The single-chip microcomputer 11-1 obtains the water depth measured by the water depth detector 15 and displays the obtained water depth on the display module 11-2. When the water depth obtained by the single-chip microcomputer 11-1 is less than the preset water depth threshold, the alarm is controlled to sound an alarm to prompt the staff to replenish water in time to avoid damage to the equipment caused by too low water level.

[0056] A first flow detector 13 is installed in the first water supply main pipe 2; a second flow detector 14 is installed in the second water supply main pipe 4; the first flow detector 13 and the second flow detector 14 are both connected to the intelligent controller 11 for communication, and the intelligent controller 11 obtains the water flow detected by the first flow detector 13 and the second flow detector 14. The intelligent controller 11 displays the detected water flow through the display module 11-2 for the staff to view, and compares the detected water flow with the preset water flow threshold, and controls the alarm to sound an alarm when it does not meet the preset water flow threshold.

[0057] A first heating component 8 is also provided in the second water supply main pipeline 4, and a second heating component 9 is provided in each of the multiple water supply pipes. The first heating component 8 and the second heating component 9 are communicatively connected with the intelligent controller 11, so that when the water in the second water supply main pipeline and the water supply pipe cannot be sprayed due to freezing in cold weather, the heating components are turned on for heating, and the heating is stopped when the second flow detector detects that the water flow in the second water supply main pipeline reaches a certain value.

[0058] The control system also includes a wireless handheld terminal 16; the wireless handheld terminal 16 is connected to the single-chip computer 11-1 through the wireless communication module 11-3, and reads the data detected by the first flow detector 13, the second flow detector 14, the multiple dust detectors 12 and the water depth detector 15 through the wireless handheld terminal 16, and sends a signal to the single-chip computer 11-1 to realize the control of the water pump 3, the first signal control valve 5, the second signal control valve 1, the first heating component 8 and the second heating component 9, thereby realizing remote control of the device, which is helpful to realize real-time monitoring of the dust situation around the environment and remote control of the device.

In particular, for the terminal embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the description in the method embodiment.
