Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent monitoring equipment, and in particular relates to intelligent monitoring equipment and methods for mine safety management. Background Art

[0002] In mine safety management, air safety is an essential core element, among which gas is one of the hidden dangers of mine air safety. As a kind of toxic and harmful gas, when the gas concentration in the air reaches 5% to 16%, it will cause explosion and cause accidents when it encounters fire.

[0003] In order to prevent safety hazards caused by excessive gas concentration, in mine safety monitoring, continuous monitoring of gas content in the air is one of the effective methods to reduce the degree of safety hazards caused by excessive gas concentration. When monitoring gas, rapid response and detection of excessive gas concentration is a more important factor in gas leakage accidents. Therefore, in mines, gas concentration detection equipment is usually distributed. However, in actual application, it is found that, on the one hand, due to the influence of funds, the distance between gas detection equipment is usually large. When the gas leakage location is far away from the gas detection equipment at both ends, the response and detection time will be extended. On the other hand, when the gas detection equipment is arranged at a small distance and the density is high, it will also lead to a large later maintenance project for the gas detection equipment.

[0004] In order to quickly determine the location of gas leakage when the distance between gas detection equipment is large, a coal mine tunnel gas leakage monitoring and positioning device and method are disclosed in the related art, with the announcement number CN118705012B. In this scheme, the detection range is expanded by moving the mobile monitor, and the gas leakage location can be determined more quickly after the gas leakage. However, in actual application, it is found that, on the one hand, due to certain limitations on the ventilation rate in the mine, when a gas leakage occurs, the delay time from the time the gas leakage occurs to the time the gas leakage is discovered is too long. On the other hand, due to the poor traffic conditions in the mine, the movement rate of the mobile monitor is slow, and the time from the time the gas leakage is discovered to the time the gas leakage location is determined is too long. Therefore, there is a defect of slow response to the gas concentration monitoring in the mine, which is not conducive to the rapid investigation of safety hazards.

[0005] In view of this, the present invention proposes an intelligent monitoring device and method for mine safety management to solve the above technical problems. Summary of the Invention

[0043] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0044] like Figures 1 to 8 As shown, the intelligent monitoring device for mine safety management according to the present invention includes an intelligent terminal and a plurality of equally spaced detection instruments, the detection instruments being used to continuously detect the air in the mine, the intelligent terminal being electrically connected to the detection instruments, and the intelligent terminal being used to connect to and control the detection instruments, and the intelligent terminal being preferably a mobile phone, a computer, etc.;

[0045] It also includes a refinement and synergistic enhancement component, which cooperates with the detection instrument to expand and refine the monitoring position of the detection instrument;

[0046] The thinning and synergistic component includes an extension tube 11, an air pump 13 and an arrangement plate 1;

[0047] The arrangement plate 1 is installed in the mine, and the arrangement plate 1 is provided with evenly distributed inspection cavities 12;

[0048] An air pump 13 is fixedly mounted on the arrangement plate 1 , and the air pump 13 corresponds to the inspection cavity 12 one by one, and the output end of the air pump 13 extends into the inspection cavity 12;

[0049] An extension tube 11 is fixedly installed at the input end of the air pump 13, and the ends of multiple extension tubes 11 are evenly arranged between two adjacent detection instruments.

[0050] When monitoring gas safety in a mine, it is necessary to use a gas detector to continuously detect the air in the mine, among which the detection of gas concentration is particularly important. When conducting long-term monitoring of gas concentration, in order to distribute the gas detectors at equal intervals in the mine and to expand and refine the monitoring range of the gas detectors, a refinement and efficiency enhancement component is provided in the present invention.

[0051] Specifically, when the detection instruments are laid out in the mine, the detection instruments are installed at equal intervals in the mine according to the original laying density, and at the same time, a refinement enhancement component is laid out at each detection instrument installation position. The refinement enhancement component includes a plurality of extension tubes 11, wherein one end of the extension tube 11 is located at the position of the detection instrument, and the other end of the extension tube 11 extends to the interval between two adjacent detection instruments. The extension tubes 11 arranged at the same detection instrument have different extension distances, and the ends of the plurality of extension tubes 11 are evenly distributed between two adjacent detection instruments. When the mine air is monitored for a long time, each extension tube 11 is installed with a plurality of extension tubes 11. The installed air pumps 13 are all working, and the air pumps 13 continuously extract the air in the extension tube 11 and pump it into the inspection chamber 12 on the arrangement plate 1, and the detection instrument inspects the air in the inspection chamber 12 one by one. When a gas leak occurs at a certain position, the gas concentration at that position gradually increases. When the detection instrument performs periodic inspections on the inspection chamber 12 one by one, it can quickly detect gas leaks in one detection cycle, and quickly determine the position of the end of the corresponding extension tube 11 filled in in advance by numbering the extension tube 11 corresponding to the inspection chamber 12, and finally transmit the information to the smart terminal for processing by the staff.

[0052] The present invention sets up multiple extension tubes 11 and evenly distributes the ends of the multiple extension tubes 11 between two adjacent detection instruments. Therefore, when the detection instruments detect the corresponding inspection cavities 12 one by one, the detection instruments can move a small distance on the arrangement plate 1 to achieve multi-point detection of a long distance between two adjacent detection instruments. Compared with the equipment in conventional technology that only detects the current position, the present invention not only expands the detection range through multi-point detection, which is convenient for rapid response after gas leakage, but also realizes rapid determination of the gas leakage position through management of the corresponding positions of the extension tubes 11.

[0053] As a preferred embodiment of the present invention, it also includes a high- and low-frequency screening component, which is used to control the screening frequency of the inspection cavity 12. The high- and low-frequency screening component includes a confluence groove 2, a high-frequency sampling hole 21, and a low-frequency sampling hole 22;

[0054] The plurality of test cavities 12 are distributed in a rectangular array, and the test cavities 12 are divided into multiple groups. The arrangement plate 1 is provided with a confluence groove 2, and the number of the confluence grooves 2 is the same as the number of the test cavities 12 groups. The confluence grooves 2 are all electrically connected to the test cavities 12 in the same group;

[0055] The arrangement plate 1 is provided with high-frequency sampling holes 21 and low-frequency sampling holes 22 . The high-frequency sampling holes 21 correspond to the confluence grooves 2 one by one and are conductively connected. The low-frequency sampling holes 22 correspond to the inspection chambers 12 one by one and are conductively connected.

[0056] As the number of refined points gradually increases, the number of extension tubes 11 and the number of test cavities 12 will increase. Therefore, the time for periodic monitoring of the test cavities 12 will be extended. In this case, the present invention sets a high- and low-frequency screening component. In the present invention, multiple test cavities 12 are arranged in a rectangular array, and a confluence trough 2 is provided above the test cavities 12. The confluence trough 2 is connected to the test cavities 12 of the same group. At the same time, a high-frequency sampling hole 21 and a low-frequency sampling hole 22 are provided on the confluence trough 2 and the test cavities 12. After the equipment is started, the air pump 13 extracts air and pumps It is sent to the corresponding inspection chamber 12, and then under the action of air pressure, the air in the same group of inspection chambers 12 flows into the corresponding confluence groove 2. Therefore, when the high-frequency sampling holes 21 are sampled and monitored by the detection instrument, the detected air is the mixed gas at the ends of the multiple extension tubes 11. Since the low-frequency sampling holes 22 are multiples of the high-frequency sampling holes 21, when the detection instrument performs periodic detection on the high-frequency sampling holes 21 and the low-frequency sampling holes 22 at the same speed, the number of high-frequency sampling holes 21 is small, the detection cycle is short, and the detection frequency is high, while the low-frequency sampling holes 22 are the opposite.

[0057] The present invention sets high- and low-frequency screening components. When performing high-frequency screening and low-frequency screening at the same time, it can not only utilize high-frequency high-frequency screening to achieve rapid screening of multiple areas and quickly respond to and discover obvious leakage conditions, but also utilize low-frequency low-frequency screening to achieve detailed inspection of multiple areas one by one and perform high-precision screening on less obvious leakage conditions, thereby improving the detection accuracy of gas leaks.

[0058] As a preferred embodiment of the present invention, the detection instrument includes a detector 3 and a sampler. There are two samplers, which are used to sample the low-frequency sampling hole 22 and the high-frequency sampling hole 21 respectively. The samplers are connected to the detector 3 through pipes. A high-frequency guide groove 24 and a low-frequency guide groove 25 are provided on the arrangement plate 1. The two samplers are respectively installed in the high-frequency guide groove 24 and the low-frequency guide groove 25.

[0059] The sampler includes a mounting base 31, a drive motor 32, a running wheel 33 and a cannula 34;

[0060] A driving motor 32 is mounted on the mounting seat 31, and a running wheel 33 is fixedly mounted on the output end of the driving motor 32; the running wheel 33 is frictionally connected to the high-frequency guide groove 24 and the low-frequency guide groove 25 respectively;

[0061] The mounting bases 31 are each mounted with an intubation tube 34 , and the low-frequency sampling hole 22 and the high-frequency sampling hole 21 are respectively located on a moving path of the intubation tube 34 .

[0062] When high-frequency screening and low-frequency screening are performed simultaneously, the two samplers move along the high-frequency guide groove 24 and the low-frequency guide groove 25 respectively, wherein the high-frequency guide groove 24 and the low-frequency guide groove 25 are both annular grooves. When the drive motor 32 on the mounting seat 31 is started, the drive motor 32 drives the walking wheel 33 to rotate, and the walking wheel 33 causes the two samplers to move along the high-frequency guide groove 24 and the low-frequency guide groove 25 respectively through friction with the inner walls of the high-frequency guide groove 24 and the low-frequency guide groove 25. During the movement of the sampler, the cannula 34 on the mounting seat 31 continuously collects the surrounding air. When the cannula 34 corresponds to the high-frequency sampling hole 21 or the low-frequency sampling hole 22, the detector 3 extracts the air at the location through the cannula 34 and transports it to the detector 3 to detect the gas concentration in the air. Since multiple low-frequency sampling holes 22 and high-frequency sampling holes 21 are respectively located on the moving paths of the two cannulas 34, as the two samplers continue to move, high-frequency screening and low-frequency screening can be carried out simultaneously and automatically.

[0063] As a preferred embodiment of the present invention, the ends of the extension tubes 11 corresponding to the inspection chambers 12 in the same group are adjacent. Since gas is diffusible, when the ends of the extension tubes 11 corresponding to the inspection chambers 12 in the same group are adjacent, when a gas leak occurs at one position in the same group, the gas will diffuse and will preferentially cause the air extracted by the other extension tubes 11 in the same group to change, thereby causing the air in the corresponding confluence trough 2 to change rapidly, making it easy to quickly determine the approximate location of the leak during high-frequency screening, and then determine its specific location during low-frequency screening.

[0064] The low-frequency sampling hole 22, the high-frequency sampling hole 21, and the connection between the inspection chamber 12 and the confluence groove 2 are all fixedly installed with elastic one-way plugs 5. In the initial state, the elastic one-way plug 5 is closed. A telescopic groove 35 is provided on the mounting seat 31. The insert 34 is elastically installed in the telescopic groove 35 by a spring. An exhaust pipe 4 is fixedly installed on the side of the confluence groove 2 away from the high-frequency sampling hole 21. Multiple exhaust pipes 4 extend to the outside of the mine. The setting of the elastic one-way plug 5 can make the low-frequency sampling hole 22 and the high-frequency sampling hole 21 in a closed state in the initial state. As the air pressure in the inspection chamber 12 continues to increase, the gas flows from the inspection chamber 12 to the confluence groove 2 in one direction. It is then discharged to the outside of the mine through the discharge pipe. When the sampler is sampling, when the mounting seat 31 is not aligned with the low-frequency sampling hole 22 and the high-frequency sampling hole 21, the cannula 34 is inside the telescopic groove 35, and the opening of the cannula 34 is blocked by the high-frequency guide groove 24 and the low-frequency guide groove 25. When the mounting seat 31 is aligned with the low-frequency sampling hole 22 and the high-frequency sampling hole 21, under the elastic action of the spring, the cannula 34 extends into the elastic one-way plug 5, pushing the elastic one-way plug 5 to open, and making the cannula 34 conductive with the low-frequency sampling hole 22 and the high-frequency sampling hole 21, and the gas flows into the detector 3 from the cannula 34, thereby realizing the inspection and screening of the low-frequency sampling hole 22 and the high-frequency sampling hole 21.

[0065] Inclined plates 36 are fixedly mounted on both sides of the cannula 34. The inclined plates 36 are used to assist the cannula 34 in separating from the low-frequency sampling hole 22 or the high-frequency sampling hole 21. When the cannula 34 moves following the mounting base 31, the inclined plates 36 can contact the side walls of the low-frequency sampling hole 22 and the high-frequency sampling hole 21, thereby prompting the cannula 34 to squeeze the spring into the telescopic groove 35, thereby finally achieving the storage of the cannula 34.

[0066] An intelligent monitoring method for mine safety management, the method comprising the following steps:

[0067] S1: Install intelligent monitoring devices at equal intervals in the mine according to pre-planned locations, and use communication equipment to electrically connect multiple intelligent monitoring devices;

[0068] S2: The intelligent monitoring device is started, and the air pump 13 extracts the air in the corresponding extension tube 11 and discharges the air into the inspection chamber 12 and the confluence tank 2, and then discharges the air to the outside through the exhaust pipe 4;

[0069] S3: The driving motors 32 on the two samplers are started, driving the walking wheels 33 to reciprocate in the high-frequency guide groove 24 and the low-frequency guide groove 25 respectively. During the movement, the high-frequency sampling holes 21 and the low-frequency sampling holes 22 are sampled and tested one by one;

[0070] S4: Continuously carry out high-frequency large-scale screening and low-frequency small-scale screening. When the detector 3 detects that the concentration of harmful gases in the air exceeds the standard, an alarm is issued through the communication equipment and the process is transferred to the manual processing link.
