DETAILED DESCRIPTION

[0024] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0025] It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0026] In the related art, the dust suppression vehicle suppresses dust by fixing the angle at a fixed point during dust suppression, and after the blasting is completed, the dust suppression vehicle is started to drive away, thereby causing a large amount of dust to spread, and finally the dust suppression effect is poor, and more dust suppression vehicles need to be dispatched for dust suppression.

[0027] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] Please refer to Figure 1 At least one embodiment provides a mine blasting dust suppression system, comprising: a plurality of dust suppression vehicles 100 and a control terminal; the control terminal is respectively connected with the plurality of dust suppression vehicles 100 in communication; the control terminal is configured to receive current blasting information and obtain the predicted height and predicted concentration of the current required blasting area dust from the dust suppression management database corresponding to the current blasting information, and send the predicted height and predicted concentration to the corresponding dust suppression vehicle 100; the dust suppression vehicle 100 adjusts the direction and angle of the water spray gun 132 in advance according to the received predicted height and predicted concentration, and controls the dust suppression vehicle to spray water in advance before blasting, thereby improving the dust suppression effect and improving the use efficiency of the dust suppression vehicle 100.

[0029] It should be noted that the current blasting information includes: blasting area, explosive dosage, and the dust suppression management database is constructed according to the blasting data stored in the past. Specifically, the information of blasting area, explosive dosage, dust height, and dust concentration is stored, and the corresponding dust height and dust concentration are retrieved from the dust suppression management database according to the current blasting information by means of data calling, as the corresponding predicted height and predicted concentration.

[0030] Please refer to Figure 2In some embodiments, the dust suppression vehicle 100 comprises: a walking mechanism 110; a container tank 120 arranged above the walking mechanism 110; a rotating spraying mechanism 130 arranged above the container tank 120 and in communication with the container tank 120; a control module electrically connected with the rotating spraying mechanism 130 and adapted to adjust the spraying direction and spraying height of the rotating spraying mechanism 130 according to the received predicted height and predicted concentration.

[0031] For further reference Figure 2 The dust suppression vehicle 100 further comprises: a dust detection sensor 140 arranged at the top of the container tank 120; the dust detection sensor 140 is electrically connected with the control module and is adapted to detect the actual concentration of dust in multiple directions in the corresponding area after blasting; the control module is further configured to adjust the spraying direction and spraying height of the rotating spraying mechanism 130 according to the received actual concentration of dust in multiple directions.

[0032] Specifically, the step of adjusting the spraying direction and spraying height of the rotating spraying mechanism 130 according to the received actual concentration of dust in multiple directions by the control module comprises: S1: adjusting the spraying direction according to the actual concentration of dust in multiple directions.

[0033] S2: adjusting the spraying height according to the actual concentration of dust in multiple directions.

[0034] S3: sending the adjusted data to a control terminal and storing it in a dust suppression management database for subsequent use.

[0035] Due to the wind direction and wind speed, the center point of the dust will change, and by detecting the actual concentration of dust to adjust the spraying direction and spraying height of the water gun 132, the dust suppression effect is maximized, thereby improving the blocking efficiency.

[0036] For reference Figure 5 At the same time, after dust suppression, part of the dust will be beyond the current spraying range of the water gun 132, and the concentration of the area not suppressed during dust suppression will be higher than that in the current spraying range of the water gun 132. At this time, by re-determining the center point of the dust and adjusting the spraying height and direction of the water gun 132, the dust suppression effect is improved. The adjustment of the spraying direction is shown in F1 of Figure 5 .

[0037] Specifically, the step of adjusting the spraying direction according to the actual concentration of dust in multiple directions by the control module comprises: receiving the actual concentration of dust in multiple directions; screening out the dust center direction where the maximum actual concentration of dust is located; controlling the rotating spraying mechanism 130 to rotate so that the spraying direction coincides with the dust center direction.

[0038] The step of adjusting the spraying height according to the dust actual concentration in multiple directions by the control module comprises: comparing the maximum dust actual concentration with the preset concentration; if the dust actual concentration is greater than the first preset concentration, controlling the rotating spraying mechanism 130 to adjust the spraying angle upward at a preset speed until the dust actual concentration is less than or equal to the first preset concentration; if the dust actual concentration is less than the second preset concentration, controlling the rotating spraying mechanism 130 to adjust the spraying angle downward at a preset speed until the dust actual concentration is greater than or equal to the second preset concentration; wherein the first preset concentration is greater than the second preset concentration, and the first preset concentration and the second preset concentration are set according to the predicted concentration.

[0039] Specifically, the first preset concentration is 1.3 times the predicted concentration, and the second preset concentration is 0.7 times the predicted concentration.

[0040] Please continue to refer to Figure 2 and Figure 3 In some embodiments, the rotating spraying mechanism 130 comprises: a horizontal rotating seat 131 rotationally arranged at the top of the container tank 120; a water gun 132 rotationally arranged on the horizontal rotating seat 131 through a horizontal rotating shaft 135; a direction adjusting motor 133 for driving the horizontal rotating seat 131 to rotate in the horizontal direction, thereby adjusting the spraying direction of the water gun 132; and a height adjusting motor 134 for driving the horizontal rotating shaft 135 to rotate, thereby adjusting the spraying height of the water gun 132.

[0041] Please refer to Figure 4 In some embodiments, the mine blasting dust suppression system further comprises an air charging vehicle 200 for charging the container tank 120 of the dust suppression vehicle 100.

[0042] Please continue to refer to Figure 1 and Figure 2 The dust suppression vehicle 100 further comprises a dust suppressant sprayer 150 arranged at the top of the container tank 120, and the inside of the container tank 120 is further provided with a containing cavity for storing the dust suppressant.

[0043] The control module is further configured to obtain an escape area beyond the spraying range of the rotating spraying mechanism 130 according to the received dust actual concentration in multiple directions, and control the dust suppressant sprayer 150 to spray the dust suppressant towards the escape area. The escape area is shown in Figure 5 The path of the dust suppressant sprayed by the dust suppressant sprayer 150 is shown in Figure 5

[0044] ​In use, the dust suppression agent is first sprayed by the rotating spraying mechanism 130, and then sprayed by the dust suppression agent sprayer towards the escape area, so as to quickly absorb the dust in the escape area. At the same time, by adjusting the spraying direction and angle of the water gun 132, the dust suppression in the escape area is further accelerated.

[0045] Due to the height of the escaped dust, the height of the dust suppression agent sprayed by the dust suppression agent sprayer 150 is higher than the height of the liquid sprayed by the rotating spraying mechanism 130. After the dust is absorbed by the dust suppression agent, it falls into the area with liquid, so that the adsorption holes on the surface of the dust suppression agent are filled with liquid, thereby avoiding secondary dust raising caused by the dust in the dust suppression agent after falling to the ground.

[0046] Please refer to Figure 6 At least one embodiment also provides a dust suppression method of the mine blasting dust suppression system as described above, the method comprising: S110: constructing a dust suppression management database.

[0047] S120: obtaining the area of the required blasting area and the amount of explosive.

[0048] S130: obtaining the number of required dust suppression vehicles 100 and the position of each dust suppression vehicle 100 from the dust suppression management database according to the area of the blasting area.

[0049] S140: obtaining the predicted height and predicted concentration of dust raising in the dust suppression area of each dust suppression vehicle 100 from the dust suppression management database according to the area and the amount of explosive.

[0050] S150: sending the position, predicted height and predicted concentration of the dust suppression vehicle 100 to the corresponding dust suppression vehicle 100.

[0051] S160: dust suppression according to the received predicted height and predicted concentration.

[0052] Among them, step S160 is: adjusting the spraying direction and spraying height of the rotating spraying mechanism 130 according to the received predicted height and predicted concentration.

[0053] In a preferred embodiment, after step S160, the dust suppression method of the mine blasting dust suppression system further comprises: S171: detecting the actual concentration of dust in multiple directions in the corresponding area after blasting by the dust detection sensor 140 on the dust suppression vehicle 100.

[0054] S172: adjusting the spraying direction according to the actual concentration of dust in multiple directions.

[0055] S173: Adjusting the spraying height according to the actual dust concentration in multiple directions.

[0056] Due to the wind direction and wind speed, the center point of the dust raising changes. By detecting the actual dust concentration, the spraying direction and the spraying height of the water jet gun 132 are adjusted to maximize the suppression of the dust raising, thereby improving the blocking efficiency.

[0057] At the same time, after dust suppression, part of the dust will be beyond the current spraying range of the water jet gun 132. During dust suppression, the concentration in the area not suppressed will be higher than that in the current spraying range of the water jet gun 132. At this time, by re-determining the center point of the dust raising and adjusting the spraying height and direction of the water jet gun 132, the dust suppression effect is improved.

[0058] Specifically, the step of adjusting the spraying direction according to the actual dust concentration in multiple directions includes: receiving the actual dust concentration in multiple directions; screening the dust center direction where the maximum actual dust concentration is located; and controlling the rotating spraying mechanism 130 to rotate so that the spraying direction coincides with the dust center direction.

[0059] The step of adjusting the spraying height according to the actual dust concentration in multiple directions includes: comparing the maximum actual dust concentration with the preset concentration; if the actual dust concentration is greater than the first preset concentration, controlling the rotating spraying mechanism 130 to adjust the spraying angle upward at a preset speed until the actual dust concentration is less than or equal to the first preset concentration; if the actual dust concentration is less than the second preset concentration, controlling the rotating spraying mechanism 130 to adjust the spraying angle downward at a preset speed until the actual dust concentration is greater than or equal to the second preset concentration; wherein the first preset concentration is greater than the second preset concentration, and the first preset concentration and the second preset concentration are set according to the predicted concentration.

[0060] Specifically, the first preset concentration is 1.3 times the predicted concentration, and the second predicted concentration is 0.7 times the predicted concentration.

[0061] In the preferred embodiment, after the step of suppressing dust according to the received predicted height and predicted concentration, the dust suppression method of the mine blasting dust suppression system further includes: controlling the dust suppressant sprayer 150 to spray the dust suppressant towards the escape area; wherein the escape area is the part of the dust generation range beyond the spraying range.

[0062] In use, the rotating spraying mechanism 130 is first controlled to spray the dust suppression agent, and then the dust suppressant sprayer is controlled to spray the dust suppressant towards the escape area, thereby quickly absorbing the dust in the escape area. At the same time, by adjusting the spraying direction and angle of the water jet gun 132, the suppression of the dust in the escape area is further accelerated.

[0063] The mine blasting dust suppression system and the dust suppression method thereof improve the dust suppression effect and the use efficiency of the dust suppression vehicle 100 by constructing a dust suppression management database, obtaining the predicted height and the predicted concentration of the flying dust of the current required blasting area according to the dust suppression management database, and adjusting the direction and the angle of the water spray gun 132 in advance according to the predicted height and the predicted concentration.

[0064] In summary, the mine blasting dust suppression system and the dust suppression method thereof provided by the present application comprise a plurality of dust suppression vehicles 100 and a control terminal, the control terminal is respectively connected with the plurality of dust suppression vehicles 100 in communication, the control terminal is configured to obtain the predicted height and the predicted concentration of the flying dust of the current required blasting area according to the dust suppression management database, and send the predicted height and the predicted concentration to the corresponding dust suppression vehicle 100, and the dust suppression vehicle 100 performs dust suppression in advance according to the received predicted height and predicted concentration. By constructing a dust suppression management database, obtaining the predicted height and the predicted concentration of the flying dust of the current required blasting area according to the dust suppression management database, and adjusting the direction and the angle of the water spray gun 132 in advance according to the predicted height and the predicted concentration, the dust suppression effect is improved, and the use efficiency of the dust suppression vehicle 100 is improved.
