Description

Technical Field

[0001] The utility model relates to the technical field of coal mine personnel safety, in particular to a monitoring device for unsafe behaviors of coal mine workers. Background Technique

[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas, generally divided into underground coal mines and surface coal mines. With the rapid development of the coal industry, coal mine safety issues have become increasingly prominent. In particular, the unsafe behaviors of coal mine workers have become one of the main reasons for frequent coal mine accidents.

[0003] After retrieval, the utility model with the publication number of CN215128765U discloses a comprehensive safety psychological detection device for coal mine special operators, including a housing. A motor box is welded to the top of one side of the housing. The inner side wall of the motor box is connected to a motor by bolt threads. The output shaft of the motor penetrates through one side of the housing and is welded to a fixed rod. By driving the fixed rod to rotate by the motor, the sponge block moves up and down, used to simulate the situation of mine collapse, so as to observe the reactions and operations of special operators when facing mine collapse, and the comprehensive psychological conditions of the personnel can be observed; by using an air pump to extract and discharge the external gas containing indole, the situation of gas leakage inside the mine can be simulated. By observing the reactions of special operators when facing gas leakage, and by observing the operations of the staff in the face of these situations and their heart rate changes, the comprehensive psychological conditions of the staff can be understood more intuitively.

[0004] The above-mentioned monitoring device for operators still has some deficiencies in the actual use process:

[0005] 1. The simulation device drives the connecting rope to contract by rotating the fixed rod to drive the sponge block to lift and lower to simulate the collapse scene. However, during the collapse process, the mine collapses downward by gravity. By rotating the fixed rod to drive the connecting rope to make the sponge fall, the falling speed of the sponge is slow, and the simulation authenticity is poor.

[0006] 2. Although the device can simulate the scenes of mine collapse and gas leakage for operators, detect and monitor the reactions, operations and heart rate changes of the staff, the simulation form is relatively single, the reduction degree of the collapse scene is low, and it is difficult to effectively monitor the behaviors of the staff in unsafe scenes. Content of the Utility Model

[0007] The purpose of the present utility model is to solve the deficiencies existing in the prior art, where the sponge drops by rotating the fixed rod to drive the connecting rope, the dropping speed of the sponge is slow, the simulation authenticity is poor, the simulation form is relatively single, the reduction degree of the collapse scene is low, and it is difficult to effectively monitor the behaviors of workers in unsafe scenarios. Therefore, a monitoring device for unsafe behaviors of coal mine workers is proposed.

[0008] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0009] A monitoring device for unsafe behaviors of coal mine workers includes a simulation box body. An oscillation plate is arranged inside the simulation box body. One side of the oscillation plate is rotatably connected inside the simulation box body. A plurality of sponge blocks are placed on the top of the simulation box body. It further includes an oscillation component, and the oscillation component is located on the other side of the oscillation plate. The oscillation component can drive the other side of the oscillation plate to oscillate up and down. It also includes an opening and closing component, and the opening and closing component is located on the top of the simulation box body. The sponge is placed on the opening and closing component, and the dropping of the sponge block is controlled by the opening of the opening and closing component.

[0010] In a possible design, the oscillation component includes a connecting frame rotatably connected to the other side of the oscillation plate. A rotating frame is rotatably connected inside the simulation box body. An empty slot is arranged inside the rotating frame, and the other end of the connecting frame is rotatably connected to the empty slot of the rotating frame and is located at an eccentric position far from the center of the circle. A third driving motor is fixedly installed inside the simulation box body. By the rotation of the output shaft of the third driving motor, the rotating frame can be driven to rotate. Through the circular motion of the other end of the connecting frame around the rotating frame, the oscillation plate can be pulled up and down.

[0011] In a possible design, the opening and closing component includes a plurality of first clamping plates rotatably connected to the top of the simulation box body. A first connecting shaft is fixedly penetrated through each of the plurality of first clamping plates, and both ends of the first connecting shaft are rotatably connected inside the simulation box body. A plurality of second opening and closing plates are arranged on the top of the simulation box body. A second connecting shaft is fixedly penetrated through each of the plurality of second opening and closing plates, and both ends of the second connecting shaft are rotatably connected inside the simulation box body. The first clamping plates and the second opening and closing plates open and close with each other. One end of each of the first connecting shaft and the second connecting shaft is fixedly sleeved with a first bevel gear. A rotating shaft is rotatably connected inside the simulation box body. A second driving motor is fixedly installed inside the simulation box body, and the output shaft of the second driving motor is fixedly connected to one end of the rotating shaft. A plurality of second bevel gears are fixedly sleeved on the outer wall of the rotating shaft, and the plurality of second bevel gears are respectively meshed with the plurality of first bevel gears. Adjacent two second bevel gears are arranged oppositely, and the rotating directions of adjacent two first bevel gears are opposite. Through the cooperative use of the two first bevel gears, the first clamping plates and the second opening and closing plates can be synchronously opened to allow the sponge blocks to drop naturally.

[0012] In one possible design, a plurality of winding racks are fixedly installed on the top of the simulation box body, a winding roller is rotatably connected inside the winding rack, a plurality of connecting ropes are wound around the outer wall of the winding roller, and the other end of the connecting rope is fixedly connected to the sponge block, one end of the winding roller extends to one side of the winding rack and is fixedly sleeved with a sprocket, and the plurality of sprockets are connected by chain transmission, a first drive motor is fixedly installed on the top of the simulation box body, and one end of the output shaft of the first drive motor is fixedly connected to one end of one of the winding rollers.

[0013] In a possible design, a door is hingedly connected to one side of the simulation box to facilitate entry by operators.

[0014] In one possible design, an air pump box is fixedly installed on one side of the simulation box, through which gas containing "indole" can be discharged to simulate leaked gas, an exhaust fan is fixedly installed on the other side of the simulation box, a heart rate detector is fixedly installed in the simulation box to monitor the heart rate of the staff, and a speaker is fixedly installed in the simulation box to simulate the sound of the collapse site.

[0015] In this application, the main part of the device is an analog box, which is provided with an oscillation component, an opening and closing component, and a top area for placing multiple sponge blocks. These sponge blocks are used to simulate falling objects and are used to test the behavioral responses of operators in an unsafe environment. The oscillation component consists of a connecting frame, a rotating frame, and a third driving motor. When the output shaft of the third driving motor rotates, it drives the rotating frame to rotate. Since one end of the connecting frame is rotatably connected to the oscillation plate and the other end is rotatably connected to the eccentric part of the rotating frame, the connecting frame will perform a circular motion around the rotating frame. This circular motion will be converted into an up-and-down pull on the oscillation plate, thus generating an oscillation effect. This oscillation is used to simulate the vibration in a coal mine or other unstable environments. The opening and closing component consists of a first clamping plate, a second opening and closing plate, a first connecting shaft, a second connecting shaft, a first bevel gear, a rotating shaft, a second bevel gear, and a second driving motor. The output shaft of the second driving motor can drive the rotating shaft to rotate. When the rotating shaft rotates, through the meshing of multiple second bevel gears with the first bevel gear respectively, it can drive the same group of first connecting shaft and second connecting shaft to rotate in opposite directions. Since the first connecting shaft and the second connecting shaft are respectively connected to the first clamping plate and the second opening and closing plate, this rotation will cause the first clamping plate and the second opening and closing plate to open and close. When they open, the sponge blocks at the top can fall naturally, simulating the situation of objects falling in a coal mine. There is a system consisting of a winding frame, a winding roller, a connecting rope, a sponge block, a sprocket, a chain, and a first driving motor at the top of the analog box, which can realize the automatic recovery and re-release of the object sponge blocks. When the output shaft of the first driving motor rotates, it drives multiple winding rollers to rotate, and then the winding rollers rotate to release or recover the connecting rope wound around them. Since the other end of the connecting rope is fixedly connected to the sponge block, the sponge block can be released or recovered. In addition, multiple sprockets are connected by chain drive, which can ensure the synchronous rotation of multiple winding rollers, so as to realize the synchronous release or recovery of multiple object sponge blocks. The gas pump box can discharge the gas containing "indole" to simulate the leakage of harmful gases that may exist in a coal mine. At the same time, the exhaust fan is used to discharge these gases to keep the air circulation in the container. The heart rate detector is used to monitor the heart rate of the operator in real time to evaluate their physiological responses and psychological changes in the simulated environment. The sound box is used to simulate the sounds of collapses or other emergency situations that may occur in a coal mine. The hatch hinged on one side of the analog box can be opened to facilitate the operator to enter the container for testing. During the test, the operator may need to wear specific safety equipment or perform specific operations to simulate the real coal mine working environment. Beneficial effects

[0016] In the present utility model, for the monitoring device of unsafe behaviors of coal mine workers, through the oscillation component, the device can simulate the vibrations and unstable environments in coal mine operations, enabling workers to conduct training and tests in a more realistic environment. This simulation helps workers better adapt to the actual working environment and improve their ability to handle emergencies.

[0017] In the present utility model, for the monitoring device of unsafe behaviors of coal mine workers, the design of the opening and closing component enables the sponge block to automatically fall, and the recovery and re-release of the sponge block are achieved through the winding roller. This not only improves the test efficiency but also reduces the complexity of manual operations. At the same time, the built-in heart rate detector in the device can monitor the physiological reactions of workers in real time, providing objective data for evaluating unsafe behaviors.

[0018] In the present utility model, the clamping component is used to place the sponge block. When the sponge block suddenly opens, it can simulate the scene of a coal mine collapse. At the same time, the recovery and re-release of the sponge block are achieved through the winding roller, making the simulation effect of the collapse more realistic. Meanwhile, the vibrations in coal mine operations, the collapse of the coal mine, the leakage of toxic gases, and various sounds at the collapse site are simulated, making the simulated scene more realistic, effectively improving the authenticity of the data on the physiological reactions and psychological changes of coal mine workers in an unsafe behavior environment.

[0025] Referring to Figure 1 and Figure 2 A device for monitoring unsafe behaviors includes a simulated box body 1. An oscillating plate 16 is provided inside the simulated box body 1. One side of the oscillating plate 16 is rotatably connected inside the simulated box body 1. A plurality of sponge blocks 7 are placed on the top of the simulated box body 1. It further includes an oscillating component, and the oscillating component is located on the other side of the oscillating plate 16. The oscillating component can drive the other side of the oscillating plate 16 to oscillate up and down. It also includes an opening and closing component, and the opening and closing component is located on the top of the simulated box body 1. The sponge is placed on the opening and closing component, and the dropping of the sponge blocks 7 is controlled by the opening of the opening and closing component. The main part of the device is the simulated box body 1, which is provided with an oscillating component, an opening and closing component, and a top area for placing a plurality of sponge blocks 7. These sponge blocks 7 are used to simulate falling objects and are used to test the behavioral responses of operators in an unsafe environment.

[0026] Referring to Figure 2 and Figure 4 The oscillating component includes a connecting frame 20 rotatably connected to the other side of the oscillating plate 16. A rotating frame 14 is rotatably connected inside the simulated box body 1. An empty slot is provided inside the rotating frame 14, and the other end of the connecting frame 20 is rotatably connected to the empty slot of the rotating frame 14 and is located at an eccentric position away from the center of the circle. A third driving motor 15 is fixedly installed inside the simulated box body 1. By the rotation of the output shaft of the third driving motor 15, the rotating frame 14 can be driven to rotate. Through the circumferential movement of the other end of the connecting frame 20 around the rotating frame 14, the oscillating plate 16 can be pulled up and down. The oscillating component is composed of the connecting frame 20, the rotating frame 14, and the third driving motor 15. When the output shaft of the third driving motor 15 rotates, it drives the rotating frame 14 to rotate. Since one end of the connecting frame 20 is rotatably connected to the oscillating plate 16 and the other end is rotatably connected to the eccentric position of the rotating frame 14, the connecting frame 20 will perform a circumferential movement around the rotating frame 14. This circumferential movement is converted into the up and down pulling of the oscillating plate 16, thereby generating an oscillating effect. This oscillation is used to simulate the vibration in a coal mine or other unstable environments.

[0027] Referring to Figure 3, the opening and closing assembly includes a plurality of first engaging plates 12 rotatably connected to the top of the simulation box 1. A first connecting shaft 13 is fixedly penetrated through each of the plurality of first engaging plates 12, and both ends of the first connecting shaft 13 are rotatably connected within the simulation box 1. A plurality of second opening and closing plates 21 are provided on the top of the simulation box 1. A second connecting shaft 19 is fixedly penetrated through each of the plurality of second opening and closing plates 21, and both ends of the second connecting shaft 19 are rotatably connected within the simulation box 1. The first engaging plates 12 and the second opening and closing plates 21 open and close with each other. A first bevel gear 17 is fixedly sleeved on one end of each of the first connecting shaft 13 and the second connecting shaft 19. A rotating shaft 22 is rotatably connected within the simulation box 1. A second driving motor 11 is fixedly installed within the simulation box 1, and the output shaft of the second driving motor 11 is fixedly connected to one end of the rotating shaft 22.

Adjacent two second bevel gears 18 are arranged oppositely, and the rotation directions of adjacent two first bevel gears 17 are opposite. Through the cooperation of the two first bevel gears 17, the first engaging plates 12 and the second opening and closing plates 21 can be correspondingly driven to open synchronously, for the natural dropping of the sponge block 7. The opening and closing assembly is composed of the first engaging plates 12, the second opening and closing plates 21, the first connecting shaft 13, the second connecting shaft 19, the first bevel gears 17, the rotating shaft 22, the second bevel gears 18 and the second driving motor 11. The output shaft of the second driving motor 11 can drive the rotating shaft 22 to rotate. When the rotating shaft 22 rotates, through the engagement of the plurality of second bevel gears 18 with the first bevel gears 17 correspondingly, the same group of the first connecting shaft 13 and the second connecting shaft 19 can be driven to rotate in opposite directions. Since the first connecting shaft 13 and the second connecting shaft 19 are respectively connected to the first engaging plates 12 and the second opening and closing plates 21, this kind of rotation will cause the first engaging plates 12 and the second opening and closing plates 21 to open and close. When they open, the sponge block 7 located at the top can naturally drop.
