Description

Technical Field

[0001] The present invention relates to the technical field of coal mining, and in particular to a coal mine dust control system for a tunnel. Background Art

[0002] A large amount of dust is generated during coal mining, which seriously affects the health of workers and can easily induce pneumoconiosis.

[0003] In order to reduce dust in coal mine tunnels, spraying is usually used in the prior art. Specifically, spray heads are installed at intervals on the top of the tunnel. When coal mining is carried out, the spray heads can be turned on, and the liquid sprayed from the spray heads can reduce dust in the air.

[0004] However, the sprinkler heads in the prior art are mostly opened manually when supervisors observe or detect a high dust concentration through corresponding devices, which has a poor dust control effect. Utility Model Content

[0005] The purpose of the present invention is to provide a coal mine dust control system for a roadway, which automatically controls the opening and closing of a nozzle according to dust concentration information in the roadway, thereby improving the dust control effect.

[0006] To achieve the above objectives, the present disclosure provides a coal mine dust control system for a roadway, the coal mine dust control system comprising:

[0007] a sprinkler head configured to be mounted on the top of the laneway;

[0008] A dust concentration information collection device, the dust concentration information collection device is configured to be installed in the tunnel and corresponds to the position of the sprinkler head, and is used to collect dust concentration information in the tunnel;

[0009] An analysis device, the analysis device is used to analyze the dust concentration information;

[0010] A control device, the control device is coupled with the spray head, the dust concentration information collection device and the analysis device respectively;

[0011] The control device controls the sprinkler head to be turned on or off according to the analysis result generated by the analysis device after analyzing the dust concentration information.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] The control device controls the opening and closing of the sprinkler head according to the analysis result of the analysis device. Specifically, when the analysis result shows that the dust concentration in the tunnel is high, the control device controls the sprinkler head to open, thereby reducing the dust concentration; when the analysis result shows that the dust concentration in the tunnel is low, the control device controls the sprinkler head to close. Thus, through the mutual cooperation of the dust concentration information collection device, the control device and the analysis device, the accuracy of dust control is improved and the dust control effect is improved.

[0024] The technical solution of the present disclosure is further described below in conjunction with the accompanying drawings and through specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the present disclosure, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings, rather than all of them.

[0025] Some directional words are defined in the present disclosure. Unless otherwise stated, the directional words used, such as "up", "down", "left", "right", "inside" and "outside", are used for ease of understanding and therefore do not constitute a limitation on the scope of protection of the present disclosure.

[0026] In the present disclosure, unless otherwise expressly specified and limited, a first feature being “above” or “below” a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being “above”, “above”, and “above” a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0027] In the description of the present disclosure, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0028] Figure 1 A schematic diagram of a coal mine dust control system for a roadway provided in an embodiment of the present disclosure is shown. Roadway 1 is an underground passage, one end of which is located on the surface, and the other end of which is connected to the mining face, so that construction workers can pass through roadway 1. The cross section of roadway 1 is generally circular or quasi-circular, but is not limited thereto.

[0029] A spray assembly 2 is usually installed in the tunnel 1. The spray assembly 2 is used to spray liquid in the tunnel 1. The liquid is usually water, but it can also be water doped with other suitable solutes known in the prior art. When the dust concentration in the tunnel 1 is high, the spray assembly 2 can be turned on, and the liquid sprayed from the spray assembly 2 can absorb part of the dust, thereby reducing the dust concentration.

[0030] The spray assembly 2 includes a liquid reservoir 23, a spray head 21, and a pipe 22 connected between the liquid reservoir 23 and the spray head 21. The liquid reservoir 23 refers to a container for storing liquid, such as a liquid storage tank, a liquid storage pool, etc. The spray head 21 can be any device known in the prior art that can spray liquid (especially atomize), such as a fire sprinkler 21, and the sprinkler 21 is generally installed at the top of the tunnel 1. When the sprinkler 21 is turned on, the liquid in the liquid reservoir 23 is sprayed from the sprinkler 21 through the pipe 22; when the sprinkler 21 is turned off, no liquid is sprayed from the sprinkler 21.

[0031] In this embodiment, a dust concentration information collection device 3, such as a dust concentration detector 31 and / or a camera 32, is also installed in the tunnel 1. The dust concentration detector 31 can detect the dust concentration value, and the camera 32 can take photos in the tunnel 1. The photos reflect the spatial distribution state of the dust in the tunnel 1. The so-called spatial distribution state refers to the degree of dust aggregation in the space. When the degree of dust aggregation is higher, the visibility of the space is lower; conversely, when the degree of dust aggregation is lower, the visibility of the space is higher.

[0032] It can be seen that, in this embodiment, the dust concentration information collected by the dust concentration information collection device 3 may be the dust concentration value and / or the spatial distribution state of the dust.

[0033] It should be noted that when the dust concentration information includes both the dust concentration value and the spatial distribution state of the dust, the dust concentration information can be better expressed. For example, when the dust concentration value at the location of the dust concentration detector 31 is relatively low, and other locations in the space have accumulated more dust, using only the dust concentration detector 31 cannot express the dust concentration information well. For another example, although the dust has a high degree of aggregation at certain locations in the space, and the dust concentration value in the main activity space of the construction workers is low, using only the camera 32 cannot express the dust concentration information well. The combination of the dust concentration detector 31 and the camera 32 can advantageously solve the above problems.

[0034] In addition, when the dust concentration detector 31 and the camera 32 are provided at the same time, in order to further improve the accuracy of the dust concentration information, the dust concentration detector 31 and the camera 32 can be respectively provided on opposite side walls of the tunnel 1. Specifically, the dust concentration detector 31 can be installed on the first side wall of the tunnel 1, and the camera 32 can be installed on the second side wall of the tunnel 1, wherein the first side wall and the second side wall are arranged relative to each other, so that the dust concentration detector 31 and the camera 32 are respectively located at different positions and are far apart from each other, so that the detected dust concentration information is less random.

[0035] In addition, the position of the dust concentration information collection device 3 corresponds to the position of the spray head 21. Specifically, the distance between the dust concentration information collection device 3 and the spray head 21 along the length direction of the tunnel 1 can be set to be relatively small, for example, not more than 1m, or not more than 0.5m, and especially not more than 0.2m, so that the dust concentration information collection device 3 collects dust concentration information close to the position of the spray head 21.

[0036] In addition, if Figure 2As shown, the spray assembly 2 may also include a sprayer consisting of a plurality of spray heads 21. In the sprayer, the plurality of spray heads 21 face different directions, so that the liquid sprayed from the sprayer can cover a larger range. Specifically, the sprayer may include four spray heads 21, and the four spray heads 21 are evenly arranged around the circumference. Furthermore, the spray directions of the two opposite spray heads 21 are opposite.

[0037] Figure 3 A block diagram of a coal mine dust control system for a tunnel provided by an embodiment of the present disclosure is shown. The dust concentration information acquisition device 3 is coupled to the control device 5, so that the control device 5 can obtain the dust concentration information collected by the dust concentration information acquisition device 3. In addition, the control device 5 is also coupled to the analysis device 4, so that the control device 5 can transmit the dust concentration information from the dust concentration information acquisition device 3 to the analysis device 4. The analysis device 4 analyzes the dust concentration information to generate an analysis result, and the analysis device 4 transmits the analysis result to the control device 5. In addition, the control device 5 is also coupled to the spray head 21, so that the control device 5 can control the spray head 21 to be turned on or off according to the analysis result.

[0038] In this embodiment, coupling refers to that two devices are connected in a wired / wireless manner, so that information can at least be transmitted from one device to another.

[0039] In this embodiment, the control device 5 can be a smart device such as a computer, a tablet computer, a mobile phone, etc.

[0040] In this embodiment, the analysis device 4 may be a device having an analysis function, for example, the analysis device 4 includes an artificial neural network, in particular a convolutional neural network. Figure 4 A schematic diagram of a six-layer convolutional neural network provided in this embodiment is shown. When the dust concentration information is input into the convolutional neural network, the analysis result is finally obtained after being processed by the convolution layer and the pooling layer.

[0041] It should be noted that this embodiment does not involve improvements to artificial neural networks. For example, the publication number CN113777000A, entitled A dust concentration detection method based on neural network, has disclosed that dust concentration information can be used to obtain analysis results.

[0042] The use process of the coal mine dust control system for tunnel 1 provided in this embodiment is as follows:

[0043] Step 1: The dust concentration information collection device 3 collects dust concentration information in the tunnel 1;

[0044] Step 2: The control device 5 receives the dust concentration information from the dust concentration information collecting device 3, and transmits the dust concentration information to the analyzing device 4;

[0045] Step 3: The analysis device 4 generates an analysis result according to the dust concentration information, and transmits the analysis result to the control device 5;

[0046] Step 4: The control device 5 controls the sprinkler head 21 to open or close according to the analysis result.
