Description

[0001] The present invention relates to the technical field of coal mines, and in particular to a detection device. Background Art

[0002] At present, coal mines emit a large amount of dust into the air in various links such as production, storage, transportation and tunnel excavation. Generally, dust larger than 10μm is easily captured by nasal and tracheal mucus and gradually discharged from the body. Dust smaller than 10μm can penetrate deep into the trachea, and 90% of dust smaller than 5μm can be deposited on the trachea and alveoli, causing alveolar fibrosis, thus affecting human health and causing great harm to the human body.

[0031] In order to solve the problem in the prior art that it is impossible to evaluate the dust control effects of various dust control measures under different working conditions, the present application provides a detection device.

[0032] like Figures 1 to 4As shown, the detection device is arranged in the simulated tunnel, and the detection device includes a simulation device, a first detection device and a second detection device. The simulation device includes a main assembly 10, at least two swing assemblies 20, a rotating assembly 30 and a dust generating assembly 40, and at least two swing assemblies 20 are flippably arranged at opposite ends of the main assembly 10. The rotating assembly 30 is rotatably arranged at one end of the swing assembly 20 away from the main assembly 10, and the rotating assembly 30 has a spray hole 31. The dust generating assembly 40 is arranged on the main assembly 10, and the dust generating assembly 40 has a storage cavity for storing impurities. The dust generating assembly 40 is connected to at least one rotating assembly 30 to drive the impurities to be sprayed out from the spray hole 31. The first detection device is arranged on the simulated tunnel to detect the speed and volume of the gas in the simulated tunnel. The second detection device is arranged on the simulated tunnel to detect the concentration of impurities in the simulated tunnel.

[0033] The technical solution of this embodiment is applied, and the detection equipment is arranged in the simulated tunnel. The simulation device of the detection equipment includes a main assembly 10, at least two swing assemblies 20, a rotating assembly 30 and a dust generating assembly 40. At least two swing assemblies 20 are arranged flipably on opposite ends of the main assembly 10. The rotating assembly 30 is rotatably arranged on one end of the swing assembly 20 away from the main assembly 10, and the rotating assembly 30 has an injection hole 31. The dust generating assembly 40 is arranged on the main assembly 10, and the dust generating assembly 40 has a storage chamber for storing impurities. The dust generating assembly 40 is connected to at least one rotating assembly 30 to drive the impurities to be ejected from the injection hole 31. The first detection device is arranged on the simulated tunnel to detect the speed and volume of the gas in the simulated tunnel. The second detection device is arranged on the simulated tunnel to detect the concentration of impurities in the simulated tunnel. In this way, the simulation device can simulate the dynamic movement of the coal mining machine during the coal mining process. The arrangement of the dust generating assembly 40 can simulate the state of the coal mining machine emitting dust under different mining conditions. The first detection device is set up in a manner that can detect the wind speed and air volume in the tunnel, and simulate the wind speed and air volume in the tunnel during the coal mining process of the coal mining machine. The above-mentioned setting ensures the similarity between the detection equipment and the real working environment, and ensures the reliability and reference of the test results. The staff simulates the dust emission under different working conditions by adjusting the dust emission and wind speed and air volume, and then adopts different dust control measures to control the dust, and evaluates the dust control effects of various dust control measures according to the detection results of the second detection device, so that the staff can select the dust control measures with the best dust control effect in actual mining, thereby ensuring the safety of the staff's working environment, and then solving the problem that the prior art cannot evaluate the dust control effects of various dust control measures under different working conditions. At the same time, the setting of the swing component 20 can also simulate the motion state of different coal mining machines, thereby improving the versatility and testing flexibility of the detection equipment. At the same time, the setting method of the second detection device enables the staff to not only adjust the dust emission and wind speed and volume according to the test results before implementing dust control measures, so as to further ensure the authenticity of the test environment; but also compare the test results before and after the implementation of dust control measures to evaluate the dust control effect, thereby ensuring the reliability of the test results and, in turn, the detection reliability of the detection equipment.

[0034] In this embodiment, the simulated tunnel is provided with an air supply device to simulate the wind in the tunnel during coal mining.

[0035] In this embodiment, the first detection device is a wind speed and wind volume measuring instrument.

[0036] In this embodiment, the second detection device is one of a smoke concentration meter and a smoke concentration monitor.

[0037] In this embodiment, the impurities are dust.

[0038] In this embodiment, the first detection device is arranged on the simulation lane behind the simulation device.

[0039] In this embodiment, the measuring points of the second detection device are respectively set at 10 to 15 meters on the return air side of the coal mining machine, 3 to 5 meters from the driver's work point, and 3 to 5 meters on the return air side of various staff members.

[0040] like Figure 1 and Figure 2 As shown, the dust generating assembly 40 includes a connecting structure 41 and a driving structure. One end of the connecting structure 41 is connected to the storage chamber, and the other end of the connecting structure 41 is connected to the injection hole 31. The driving structure is arranged in the storage chamber to drive the impurities to move to the injection hole 31 through the connecting structure 41. In this way, the dust generating assembly 40 is connected to the rotating assembly 30 through the connecting structure 41, and drives the dust to the rotating assembly 30 through the driving structure, and sprays it out from the injection hole 31 to simulate the dust generation degree during the mining process of the coal mining machine. At the same time, the staff can control the dust emission through the dust generating assembly 40, so as to simulate the dust generation of the coal mining machine under different working conditions, improve the versatility of the simulation device, ensure the simulation reliability of the simulation device, and thus ensure the detection reliability of the detection equipment.

[0041] like Figure 1 and Figure 2 As shown, the rotating assembly 30 has a rotating cavity 32, and the rotating assembly 30 includes a rotating structure 33. The rotating structure 33 is rotatably arranged on the swing assembly 20, and at least part of the rotating structure 33 is located in the rotating cavity 32. In this way, the rotating assembly 30 is connected to the swing assembly 20 through the rotating structure 33, ensuring the rotation reliability of the rotating assembly 30. At the same time, at least part of the rotating structure 33 is located in the rotating cavity 32, which can also avoid the influence of the external environment on the rotating structure 33, ensure the operating safety of the rotating structure 33, and extend the service life of the rotating structure 33.

[0042] like Figure 2As shown, the swing assembly 20 has a swing chamber 21, the rotating structure 33 has a rotating chamber 331, and the connecting structure 41 includes a main connecting portion 411 and a branch connecting portion 412. The main connecting portion 411 is arranged on the swing assembly 20, and at least part of the main connecting portion 411 is located in the swing chamber 21. One end of the main connecting portion 411 is connected to the storage chamber, and the other end of the main connecting portion 411 is connected to the rotating chamber 331. The branch connecting portion 412 is arranged on the rotating structure 33, and one end of the branch connecting portion 412 is connected to the rotating chamber 331, and the other end of the branch connecting portion 412 is connected to the injection hole 31. In this way, the dust in the dust generating assembly 40 moves into the rotating chamber 331 through the main connecting portion 411, and then moves to the branch connecting portion 412 through the rotating chamber 331, and is ejected through the injection hole 31 connected to the branch connecting portion 412, thereby ensuring the reliability of dust injection. At the same time, the dust can drive the rotating structure 33 to rotate during the spraying process, and then drive the rotating component 30 to rotate, so that the rotating component 30 can rotate without an additional driving device, thereby reducing the operating cost of the detection equipment and improving the economy of the detection equipment.

[0043] In this embodiment, the rotating chamber 331 includes a first cavity and a second cavity, the main connecting portion 411 is connected to the first cavity, and the branch connecting portion 412 is connected to the second cavity.

[0044] like Figures 2 to 4 As shown, there are multiple injection holes 31, and the multiple injection holes 31 are arranged at intervals along the central axis of the rotating component 30. There are multiple branch connecting parts 412, and the multiple branch connecting parts 412 are arranged one by one corresponding to the multiple injection holes 31. In this way, the above arrangement, on the one hand, enables dust to be ejected through multiple injection holes 31, expands the injection range of dust, improves the injection efficiency of dust, and thus improves the working efficiency of the dust generating component 40; on the other hand, in the process of the dust airflow driving the rotating structure 33 to rotate, the force of the rotating structure 33 is balanced, the rotation stability of the rotating structure 33 is ensured, and the dust injection is more uniform, which improves the simulation reliability of the simulation device.

[0045] like Figure 3 As shown, the communication structure 41 further includes a sealing portion 413, which is disposed between the rotating structure 33 and the main communication portion 411 to seal the gap between the rotating structure 33 and the main communication portion 411. In this way, the above arrangement avoids dust leakage due to the gap between the main communication portion 411 and the rotating structure 33, and prevents the rotating structure 33 from being driven to rotate or being ejected from the ejection hole 31, thereby ensuring the ejection reliability of the dust and the rotation reliability of the rotating structure 33.

[0046] like Figure 1As shown, the simulation device also includes at least two support assemblies 50, which are relatively arranged on one side of the main assembly 10 close to the working base surface. The support assembly 50 includes a bearing structure 51 and a lifting structure 52. The bearing structure 51 is arranged on the working base surface, one end of the lifting structure 52 is connected to the bearing structure 51, and the other end of the lifting structure 52 is connected to the main assembly 10 to drive the main assembly 10 to move toward or away from the bearing structure 51. In this way, the support assembly 50 can support the main assembly 10 and other key components arranged on the main assembly 10, ensuring the operational stability of the simulation device. At the same time, the lifting structure 52 allows the height of the simulation device to be adjusted, so that the simulation device can simulate coal mining machines of different heights, improves the flexibility and versatility of the simulation device, and further improves the versatility and test flexibility of the detection equipment.

[0047] like Figure 1 As shown, the bearing structure 51 includes a bearing portion 511 and a sliding portion 512. The bearing portion 511 is connected to the lifting structure 52. The sliding portion 512 is arranged on the bearing portion 511. The sliding portion 512 is slidably matched with the working base surface. In this way, the simulation device is slidably connected with the working base surface through the sliding portion 512, thereby realizing the operational reliability of the simulation device, enabling the simulation device to simulate the traveling state of the coal mining machine, and further ensuring the simulation reliability of the simulation device.

[0048] In this embodiment, the working base surface is provided with a guide rail, and the sliding portion 512 is slidably matched with the guide rail.

[0049] like Figure 1 As shown, the lifting structure 52 is a driving cylinder, one of the cylinder body 521 and the piston rod 522 of the driving cylinder is arranged on the bearing portion 511, and the other of the cylinder body 521 and the piston rod 522 is drivingly connected to the main assembly 10. In this way, the driving cylinder can provide a more stable driving force for the lifting structure 52, ensuring the lifting reliability of the lifting structure 52. At the same time, the above arrangement makes the arrangement positions of the cylinder body 521 and the piston rod 522 more flexible and diverse, so as to use different working conditions and usage requirements, thereby improving the processing flexibility of the staff.

[0050] In this embodiment, the driving cylinder is one of an electric cylinder and a hydraulic cylinder.

[0051] In this embodiment, the cylinder body 521 of the driving cylinder is disposed on the bearing portion 511 , and the piston rod 522 of the driving cylinder is drivingly connected to the main assembly 10 .

[0052] In an embodiment not shown in the drawings, the piston rod of the driving cylinder is arranged on the bearing portion, and the cylinder body of the driving cylinder is drivingly connected to the main body assembly.

[0053] Specifically, the swing assembly 20 includes a driving structure, a transmission structure and a swing structure 22. The driving structure is arranged on the main assembly 10. The transmission structure is arranged on the driving structure. One end of the swing structure 22 is connected to the transmission structure, and the other end of the swing structure 22 is connected to the rotating assembly 30. Among them, the driving structure is connected to the transmission structure to drive the transmission structure to drive the swing structure 22 to move. In this way, the swing assembly 20 drives the transmission structure through the driving structure, realizes the transmission of power through the transmission structure, and realizes the swinging motion through the swing structure 22, thereby realizing the simulation device to simulate the coal mining state of the coal mining machine, further ensuring the simulation reliability of the simulation device, and also ensuring the detection reliability of the detection equipment.

[0054] In this embodiment, the transmission structure is a gear box.

[0055] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
