Description

Technical Field

[0001] The present invention relates to the technical field of alcohol detection devices, and in particular to a detection device and a detection method for the safety and compliance of metal mine personnel. Background Art

[0002] In order to ensure the safety of metal mine workers, metal mine workers generally need to undergo alcohol content testing before going to work, so as to prevent some employees from breaking discipline and working after drinking, thereby avoiding safety accidents during work. Therefore, detection equipment is needed for detection and processing.

[0003] At present, in the existing technology, when conducting alcohol tests on miners, it is necessary to issue a filter to each miner. Therefore, during the test process, the filter needs to be placed on the detection device. Since there are many miners, it takes a long time to complete the detection process, which affects the detection efficiency. In addition, the filter cannot be quickly degraded after use, so it will pollute the environment. After a staff member blows, gas will remain inside the detection device. When the next miner is tested, the residual gas will enter the mouth, causing cross-infection of viruses, which will further affect the physical health of the miners. After the previous miner is tested for drinking, the residual alcohol gas inside the detection device will affect the test results of the next miner. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the background technology and to propose a detection device and a detection method for the safety and compliance of metal mine personnel.

An unwinding roller and a winding roller are respectively fixedly connected between the outer walls of the two rotating shafts corresponding to the first vertical plates. Films are wound around the outer walls of the unwinding roller and the winding roller. The films are in a tensioned state and fit tightly to the open end of the detection box. The unwinding roller is used to unwind unused films, and the winding roller is used to wind up used films, so that each miner uses a new film to avoid cross-infection of viruses;

[0007] The ventilation and deodorization mechanism includes an outlet and an inlet that pass through the upper and lower ends of the detection box. Telescopic grooves are provided on the upper and lower sides of one end of the detection box close to the wall. The two telescopic grooves are respectively connected to the outlet and the inlet. Baffles are provided on the inner walls of the two telescopic grooves. The two baffles move to open or close the outlet and the inlet, so as to quickly discharge the gas inside the detection box and prevent it from affecting the subsequent alcohol test of the mining personnel.

[0008] Preferably, the rotation replacement mechanism also includes a sprocket fixedly connected to the outer side of the first vertical plate corresponding to the rotating shaft, and the two groups of sprockets are connected by a chain, so that the rotating shaft rotates synchronously.

[0009] Preferably, the rotation replacement mechanism also includes a second vertical plate fixedly connected to one side of one of the first vertical plates at the upper end of the detection box, one end of the second vertical plate is fixedly connected to a motor, the motor driving end is fixedly connected to a main gear through a driving shaft, the outer diameter of the main gear is meshed with a sub-gear, and the sub-gear is fixedly connected to the upper rotating shaft.

[0010] Preferably, the ventilation and deodorization mechanism also includes a second pulley fixedly connected to the outer side of the sprocket corresponding to the outer wall of the rotating shaft, and a transmission shaft symmetrically connected to the left and right ends of the detection box, and the two groups of transmission shafts are fixedly connected to the first pulley at one end away from the detection box, and the four first pulleys and the four second pulleys are respectively connected by belts.

[0011] Preferably, the ends of the four first pulleys away from the detection box are fixedly connected to the first cylinder, the outer walls of the four first cylinders are rotatably connected to connecting rods, one ends of the two baffles are fixedly connected to fixed rods, both ends of the two fixed rods are fixedly connected to the second cylinders, and the four second cylinders and four connecting rods are rotatably connected respectively.

[0012] Preferably, the ventilation and deodorization mechanism also includes a fixed sleeve fixedly connected to the outer side of the corresponding outlet and inlet at the upper and lower ends of the detection box, the inner walls of the two fixed sleeves are fixedly connected to fans, and the two fixed sleeves are fixedly connected to filter plates at one end away from each other by bolts.

[0013] Preferably, the fixed sealing mechanism includes side panels fixedly connected to both sides of the film corresponding to the opening end of the detection box, and a plurality of square holes are penetrated through the two side panels, and E-shaped plates are provided on the inner walls of the two groups of square holes, and the two E-shaped plates are fixedly connected with clamping rods at one end close to each other, and the two clamping rods are fixedly connected with rubber strips for fixing the sealing film at one end close to the detection box, and the left and right ends of the detection box are fixedly connected with electric cylinders through square plates, and the telescopic ends of the two electric cylinders are fixedly connected to the two E-shaped plates respectively.

[0014] Preferably, a circular horizontal column is fixedly connected to one side of the inner wall of the detection box, an alcohol sensor is fixedly connected to the other end of the circular horizontal column, and an audible and visual alarm is fixedly connected to the upper end of the detection box.

[0016] The detection method for personnel safety compliance in metal mines includes the following steps:

[0017] Step 1: The new film can be replaced by the rotating replacement mechanism, so that every miner can use a new film to avoid cross-infection of viruses;

[0018] Step 2: The two sides of the film can be sealed by fixing the sealing mechanism to avoid air leakage from both sides between the film and the test box during use, thereby preventing the test results from being affected;

[0019] Step 3: After a miner has completed the test, the gas inside the test box can be quickly discharged and replaced with new gas through the ventilation and deodorization mechanism to avoid affecting the subsequent tests of miners.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Through the rotating replacement mechanism, the unwinding roller and the winding roller can rotate at the same time, so that the used film can be rolled up and the unused film can be unwound at the same time, so that cross infection of viruses can be prevented during alcohol testing, and the health of mining personnel in subsequent tests can be protected, and the time used for testing can be saved, and the testing efficiency can be improved. In addition, there is no need to use a filter during the test, so the production cost can be reduced, and the film can be automatically degraded to reduce pollution to the environment;

[0022] 2. Through the ventilation and deodorization mechanism, the inlet and outlet can be opened after testing a miner, and the gas inside the test box can be quickly replaced by the fan. On the one hand, it is to prevent the virus-containing gas from entering the mouth of the next miner, further preventing cross infection. On the other hand, it is to ensure the accuracy of the test results of the next miner in case there is alcohol gas left inside the test box after the previous miner is tested for drinking.

[0023] 3. The fixed sealing mechanism can be used to seal the film to prevent the contact surface between the film and the test box from warping when the miners stick to the film during the test. This can prevent the gas blown by the miners from leaking, and further ensure the accuracy of the test results. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0037] like Figure 1-Figure 11 The detection device for safety and compliance of metal mine personnel shown in the figure includes a detection box 1, and a plurality of mounting plates are fixedly connected to the detection box 1, so that the detection box 1 can be installed on a wall. The detection box 1 is provided with a rotating replacement mechanism, a fixed sealing mechanism and a ventilation and deodorization mechanism. The film 11 used can be replaced by the provided rotating replacement mechanism, so as to improve the detection efficiency, and the degradation can be completed quickly to protect the environment. The provided fixed sealing mechanism can be used to perform sealing treatment during the detection process to prevent gas leakage during the detection process and affect the detection result. The provided ventilation and deodorization mechanism can be used to quickly discharge the gas inside the detection box 1, so as to facilitate the next person to perform the detection.

[0038] like Figure 1 , Figure 5 As shown, the rotating replacement mechanism includes first vertical plates 24 symmetrically fixedly connected to the upper and lower ends of the detection box 1, and a rotating shaft 12 is rotatably passed through the two groups of first vertical plates 24. The outer walls of the two rotating shafts 12 correspond to the first vertical plates 24 and are respectively fixedly connected with a reel 6 and a reel 18. The outer walls of the reel 6 and the reel 18 are wrapped with a film 11, which is in a tensioned state and fits tightly with the open end of the detection box 1. The reel 6 is used to reel unused film 11, and the reel 18 is used to reel used film 11, so that each miner uses a new film 11 to avoid cross-infection of viruses during alcohol testing;

[0039] like Figure 8 , Fig. 9As shown, the ventilation and deodorization mechanism includes an outlet 36 and an inlet 33 which are arranged at the upper and lower ends of the detection box 1. Telescopic grooves 37 are provided on the upper and lower sides of one end of the detection box 1 close to the wall. The two telescopic grooves 37 are respectively connected with the outlet 36 and the inlet 33. Baffles 34 are provided on the inner walls of the two telescopic grooves 37. The two baffles 34 move to open or close the outlet 36 and the inlet 33, so as to quickly discharge the gas inside the detection box 1 and prevent it from affecting the subsequent alcohol test of the mining personnel.

[0040] like Figure 2 , Figure 3 As shown, the rotation replacement mechanism also includes a sprocket 20 fixedly connected to the outer side of the first vertical plate 24 corresponding to the rotating shaft 12, and the two sets of sprockets 20 are connected by a chain 16, so that the rotating shaft 12 rotates synchronously. Through the cooperation of the sprocket 20 and the chain 16, the rotating shafts 12 on the upper and lower sides can rotate synchronously, so that the film 11 can be easily replaced.

[0041] like Figure 6 As shown, the rotation replacement mechanism also includes a second vertical plate 28 fixedly connected to one side of one of the first vertical plates 24 at the upper end of the detection box 1, and a motor 29 is fixedly connected to one end of the second vertical plate 28. The driving end of the motor 29 is fixedly connected to the main gear 27 through the driving shaft. The outer diameter of the main gear 27 is meshed and connected to the sub-gear 23, and the sub-gear 23 is fixedly connected to the upper rotating shaft 12. The motor 29 is limited and fixed by the second vertical plate 28, and the motor 29 rotates with the main gear 27, and the diameter of the main gear 27 is smaller than the sub-gear 23, so it can perform deceleration movement to prevent the sub-gear 23 from rotating too fast, so that the rotating shaft 12 is at a suitable speed.

[0042] like Figure 5 , Figure 6 As shown, the ventilation and deodorization mechanism also includes a second pulley 19 fixedly connected to the outer side of the sprocket 20 corresponding to the outer wall of the rotating shaft 12, and a transmission shaft 22 symmetrically connected to the left and right ends of the detection box 1. The ends of the two sets of transmission shafts 22 away from the detection box 1 are fixedly connected to the first pulley 5, and the four first pulleys 5 and the four second pulleys 19 are connected by belts. The diameter of the first pulley 5 is much larger than the diameter of the second pulley 19, so the rotation speed of the first pulley 5 can be reduced, so more time can be reserved to quickly discharge the gas in the detection box 1.

[0043] like Figure 6 , Fig.11As shown, the ends of the four first pulleys 5 away from the detection box 1 are fixedly connected to the first cylinder 25, the outer walls of the four first cylinders 25 are rotatably connected to the connecting rods 17, the ends of the two baffles 34 are fixedly connected to the fixed rods 21, the two ends of the two fixed rods 21 are fixedly connected to the second cylinders 26, and the four second cylinders 26 and the four connecting rods 17 are rotatably connected. When the first cylinder 25 revolves around the center line of the first pulley 5, since the connecting rod 17 is rotatably connected to the first cylinder 25 and the second cylinder 26, the inclination angle of the connecting rod 17 can be changed, and the fixed rod 21 can be reciprocated outward and inward, and the fixed rod 21 moves reciprocating outward and inward with the baffle 34, so that the outlet 36 and the inlet 33 are in an open or closed state, completing the gas discharge.

[0044] like Figure 1 , Figure 2 , Figure 8 As shown, the ventilation and deodorization mechanism also includes a fixed sleeve 2 fixedly connected to the outer side of the corresponding outlet 36 and inlet 33 at the upper and lower ends of the detection box 1, and the inner walls of the two fixed sleeves 2 are fixedly connected with fans 35, and the ends of the two fixed sleeves 2 away from each other are fixedly connected with filter plates 3 by bolts. One of the fans 35 is used to blow air into the detection box 1, and the other is used to discharge the gas in the detection box 1 to the outside, so that the gas in the detection box 1 can be quickly replaced, and the filter plate 3 can block external dust and other substances to prevent them from entering the detection box 1.

[0045] like Figure 1 , Figure 8 , Fig.10 As shown, the fixed sealing mechanism includes side panels 9 fixedly connected to both sides of the film 11 corresponding to the open end of the detection box 1, and multiple square holes 30 are pierced on the two side panels 9. The inner walls of the two groups of square holes 30 are provided with E-shaped plates 13, and the two E-shaped plates 13 are fixedly connected with clamping rods 10 at one end close to each other, and the two clamping rods 10 are fixedly connected with rubber strips 14 for fixing the sealing film 11 at one end close to the detection box 1. The left and right ends of the detection box 1 are fixedly connected with electric cylinders 15 through square plates, and the telescopic ends of the two electric cylinders 15 are fixedly connected to the two E-shaped plates 13 respectively. The E-shaped plate 13 can be limited by the set square hole 30 to make it move stably. The electric cylinder 15 is controlled by the synchronous controller to make it move synchronously, so that the E-shaped plate 13 can be moved synchronously, and the clamping rod 10 and the rubber strip 14 can be moved in the direction close to the film 11. Since the rubber strip 14 can be deformed, the film 11 and the open end of the detection box 1 can be brought into close contact, thereby preventing the film 11 from warping and improving the sealing performance, thereby ensuring the accuracy of the detection.

[0046] like Figure 2 , Figure 7As shown, a circular horizontal column 32 is fixedly connected to one side of the inner wall of the detection box 1, an alcohol sensor 31 is fixedly connected to the other end of the circular horizontal column 32, an audible and visual alarm 4 is fixedly connected to the upper end of the detection box 1, and a fixing plate 7 is fixedly connected to one end of the two side panels 9, and a camera 8 is fixedly connected to one end of the fixing plate 7. The alcohol sensor 31 is fixed by the circular horizontal column 32, and the alcohol sensor 31 is used to detect the alcohol of the miners, so as to prevent the miners who drink alcohol from entering the metal mine to work, and ensure the life safety of the miners, and when the miners are detected to be drinking, the alcohol sensor 31 transmits the measured data to the control panel, and controls the audible and visual alarm 4 to sound an alarm through the control panel to remind, and the camera 8 is used to take pictures and record the miners who drink alcohol.

[0047] The detection method for personnel safety compliance in metal mines includes the following steps:

[0048] Step 1: A new film 11 can be replaced by a rotating replacement mechanism, so that each mining personnel can use a new film 11 to avoid cross infection of viruses;

[0049] Step 2: The two sides of the film 11 can be sealed by fixing the sealing mechanism to avoid air leakage from both sides between the film 11 and the detection box 1 during use, thereby preventing the test results from being affected;

[0050] Step 3: After a miner has finished the test, the gas inside the detection box 1 can be quickly discharged and replaced with new gas through the ventilation and deodorization mechanism to avoid affecting the subsequent tests of the miners.

[0051] Working principle: First, after inspecting a miner, start the electric cylinder 15 to push the E-shaped plate 13 away from the inspection box 1, and move the E-shaped plate 13 and the clamping rod 10 away from the inspection box 1 to release the limit fixation of the film 11. At this time, the start motor 29 drives the main gear 27 to rotate through the drive shaft, thereby driving the sub-gear 23 to rotate, and the sub-gear 23 drives the upper shaft 12 to rotate. Due to the existence of the sprocket 20 and the chain 16, the shafts 12 on the upper and lower sides can rotate synchronously, so the unwinding roller 6 and the winding roller 18 can rotate synchronously, and the film 11 can be replaced, so that each miner can use a new film 11, and the replacement time can be reduced during replacement, thereby improving the detection efficiency;

[0052] Furthermore, when a new film 11 is replaced, the rotating shaft 12 rotates with the second pulley 19, and the second pulley 19 rotates with the first pulley 5 through the belt, and the first cylinder 25 revolves around the center line of the first pulley 5, and the second cylinder 26 is rotatably connected to the connecting rod 17, so the inclination angle of the connecting rod 17 can be changed, and at the same time, the fixing rod 21 can be moved, and the fixing rod 21 moves with the baffle 34, and when the first pulley 5 rotates 180 degrees, the baffle 34 leaves the position of the outlet 36 and the inlet 33, and makes the outlet 36 and the inlet 33 in an open state, and during the opening process, the gas inside the detection box 1 can be quickly discharged through the fan 35, and when the first pulley 5 rotates 360 degrees, the baffle 34 covers the outlet 36 and the inlet 33 again to complete the blocking of the outlet 36 and the inlet 33, so as to facilitate subsequent detection operations;

[0053] Furthermore, after replacing the film 11 and exhausting the gas inside the detection box 1, the electric cylinder 15 is started in reverse to push the E-shaped plate 13 to move, thereby pushing the clamping rod 10 and the rubber strip 14 to move. Since the rubber strip 14 can be deformed, the contact area will be increased when it contacts the film 11, so that the clamping can be more secure, and the contact position between the film 11 and the open end of the detection box 1 can be prevented from warping, thereby ensuring the sealing effect. After that, air is blown into the detection box 1 through the holes in the film 11, and the alcohol in the gas is detected by the alcohol sensor 31. When alcohol is detected, the sound and light alarm 4 will sound an alarm to remind, and the camera 8 will take pictures and record the miners who drink.
