TECHNICAL FIELD

[0001] The present application belongs to the field of monitoring alarm devices, in particular to a tunnel gas concentration real-time monitoring device. BACKGROUND

[0002] In the process of tunnel construction, due to the need for straight line or relatively gentle curve shape construction of the tunnel, the construction path is difficult to change, and during construction, it may pass through the gas area, and once the gas concentration is too high in the process of tunnel construction, it is easy to cause explosion and cause safety accidents, therefore, the monitoring of gas is particularly important in the process of tunnel construction.

[0003] A tunnel gas concentration monitoring and early warning device is disclosed in a Chinese patent with publication number CN213298056U, which includes a shell, a gas pipe is fixedly arranged at the inner end of the shell, the upper and lower ends of the gas pipe respectively penetrate the upper and lower ends of the shell, a central controller, a gas concentration sensor and a buzzer are arranged at the inner end of the shell, a data display screen is fixedly arranged on the front wall of the shell, the sensing end of the gas concentration sensor penetrates the side wall of the gas pipe and reaches the inner end of the gas pipe, the output end of the gas concentration sensor is electrically connected with the central controller, and the output end of the central controller is electrically connected with the input end of the buzzer and the data display screen.

[0004] When monitoring the gas concentration inside the tunnel, the gas monitoring equipment is usually fixed at one place, and only the gas concentration at that place is monitored, this monitoring method can only monitor the gas concentration in a small range, in order to improve the problem of small monitoring range in the prior art, several monitoring devices are arranged at intervals inside the tunnel, which is easy to cause waste of resources.

[0005] Therefore, the present application provides a tunnel gas concentration real-time monitoring device. SUMMARY

[0006] In order to make up for the shortcomings of the prior art and solve at least one technical problem proposed in the background art.

[0007] The technical scheme adopted by the present application to solve its technical problems is: a tunnel gas concentration real-time monitoring device, comprising a sliding frame; a driving motor is fixedly connected to the side wall of the sliding frame; a fixed sleeve ring is fixedly connected to the side wall of the driving motor, and a fixed rod is fixedly connected between the fixed sleeve ring and the side wall of the sliding frame; a rotating sprocket is fixedly connected to the output end of the driving motor; a rotating sprocket is rotatably connected to the end of the sliding frame away from the rotating sprocket; a transmission chain is connected between the two rotating sprockets; a sliding block is slidably connected inside the sliding frame; the sliding block is sleeved outside the transmission chain; a push block is fixedly connected to the transmission chain; a deflector plate is rotatably connected inside the sliding block; a block protrudes from the position corresponding to the push block at the end of the deflector plate; a spring is fixedly connected between the bottom of the deflector plate and the side wall of the sliding block; the top and bottom of the sliding block are each provided with a deflector plate and are arranged in a circumferential array; a push gear is fixedly connected to the end side wall of the sliding frame and is also arranged in a circumferential array; a push gear slot is formed at the position corresponding to the push gear on the sliding block; a connecting block is fixedly connected to the side wall of the sliding block; an installation block is fixedly connected to the side wall of the connecting block; a gas detector is installed on the side wall of the installation block; when the gas concentration inside the tunnel needs to be monitored, the driving motor can be started to drive the rotating sprocket to rotate, and then the rotating sprocket can drive the transmission chain to rotate, and in the process of rotating the transmission chain, the push block can be moved, and when the push block moves to the position of the deflector plate at the bottom, it will contact the deflector plate, and then the sliding block will slide inside the sliding frame, and when the sliding block moves to the end position of the sliding frame, the push gear will enter the inside of the push gear slot, and then the deflector plate will be deflected, so that the push block can pass through the deflector plate, and then when the push block rotates to the top position along the rotating sprocket, it will push the deflector plate at the top, so that the sliding block slides in the opposite direction, the push block moves through the transmission chain, and the push of the push block on the deflector plate can make the sliding block reciprocate inside the sliding frame, so that the sliding block can drive the gas detector to move, and the range of gas concentration detection inside the tunnel can be larger, and the length of the sliding frame and the transmission chain can be adjusted adaptively according to the use scene, when the gas detector detects abnormal gas concentration, the gas concentration detected by the sensor will be converted into an electrical signal, and then transmitted to the controller, and when the gas concentration exceeds the alarm point of the controller, the alarm will send an alarm signal to remind the operator.

[0008] Preferably, a shielding plate is fixedly connected to the side wall of the sliding frame; the shielding plate is arranged at the position corresponding to the installation block; when the sliding frame is placed inside the tunnel, the blocking of the shielding plate can effectively prevent the falling rocks or other debris on the top or side wall of the tunnel from hitting the surface of the gas detector, which can easily cause damage to the gas detector.

[0009] Preferably, a first magnetic block is fixedly connected to the bottom of the pushing block; a second magnetic block is fixedly connected to the protruding part of the deflection plate; the first magnetic block and the second magnetic block are arranged in a corresponding manner; during operation, when the pushing block contacts the deflection plate, the first magnetic block will attract the second magnetic block, thereby increasing the friction between the pushing block and the deflection plate when the pushing block pushes the deflection plate, thus improving the effect of the pushing block pushing the deflection plate.

[0010] Preferably, the rotating sprocket has an internal oil storage chamber; the rotating sprocket also has several oil outlet pipes arranged in a circular pattern; the oil outlet pipes connect the oil storage chamber to the outside, and the ends of the oil outlet pipes are located near the boundary of the rotating sprocket; a baffle plate is rotatably connected to the side wall of the rotating sprocket via a torsion spring; the side wall of the baffle plate is in contact with the side wall of the transmission chain; the baffle plate is located at the corresponding end of the oil outlet pipe; an oil injection pipe is provided between the oil storage chamber and the outside, and a sealing plug is detachably installed at the end of the oil injection pipe; during operation, as the rotating sprocket rotates, it drives the transmission chain to rotate, and when the rotating sprocket and the transmission chain rotate... When the lack of lubricating oil between the chains leads to high friction between the rotating sprocket and the drive chain, the friction will cause the blocking plate to deflect. This allows the lubricating oil inside the oil reservoir to flow out through the oil outlet pipe, thus lubricating the rotating sprocket and the drive chain. At the same time, when there is too much lubricating oil on the drive chain, the lubricating oil may flow into the position of the push block. The arc-shaped arrangement of the push block and the second magnetic block allows the lubricating oil to flow down, reducing the amount of lubricating oil on the push block and decreasing the impact of lubricating oil between the push block and the deflection plate. This results in lower friction between the push block and the deflection plate. Meanwhile, the lubricating oil can flow down through the second magnetic block, thus lubricating the side wall between the deflection plate and the deflection plate.

[0011] Preferably, the bottom of the shield is provided with a plurality of cleaning bristles; during operation, as the gas detector slides back and forth, the cleaning bristles can come into contact with the surface of the gas detector, thereby cleaning the surface of the gas detector and making the surface of the gas detector cleaner.

[0012] Preferably, the sliding frame has an internal cavity; a synchronous belt is installed inside the cavity and supported by a rotating column; the ends of the synchronous belt are fixed to the side walls of the mounting block; several rotating shafts are rotatably connected inside the sliding frame and are arranged in a regular pattern; a rotating disk is fixed to the end of each rotating shaft; the rotating disk is positioned at the corresponding gas detector position; the cleaning bristles are fixed to the side wall of the rotating disk; the top of the synchronous belt is positioned at the bottom of the rotating shaft; during operation, as the mounting block reciprocates, it drives the synchronous belt to rotate, which in turn drives the rotating shaft to rotate, thus improving the cleaning effect of the rotating shaft on the surface of the gas detector, making the surface of the gas detector cleaner. Additionally, when setting up the mounting block, a groove can be cut into the bottom of the baffle plate, and the mounting block can be placed inside the groove. The groove restricts the sliding of the mounting block, making its movement more stable.

[0013] Preferably, positioning blocks are fixedly connected to both the top and bottom of the sliding block; the positioning blocks are T-shaped; positioning grooves are provided on the top and bottom sidewalls of the sliding frame at positions corresponding to the positioning blocks; guide blocks are fixedly connected to the sidewalls of the mounting block; guide grooves are provided inside the baffle plate; the guide blocks and guide grooves are arranged in a corresponding manner; during operation, when the sliding block slides inside the sliding frame, the positioning grooves restrict the positioning blocks, reducing tilting and deflection, thus making the sliding of the sliding block more stable; when the mounting block slides inside the baffle plate, the guide grooves restrict the guide blocks, making the sliding of the mounting block more stable.

[0014] Preferably, the inside of the pushing tooth is rotatably connected to an anti-wear roller; the anti-wear roller is positioned at the corresponding deflection plate position; during operation, when the pushing tooth extends into the inside of the pushing tooth groove and thus supports the deflection plate, the anti-wear roller can change the sliding friction between the pushing tooth and the deflection plate into rolling friction, thereby reducing the frictional force between the pushing tooth and the deflection plate and reducing wear between the pushing tooth and the deflection plate.

[0015] Preferably, the fixing rod is obliquely positioned opposite to the rotation direction of the drive motor. During operation, when the fixing rod supports the drive motor, the obliquely positioned fixing rod allows for greater support between the fixing rod and the drive motor, resulting in better support from the drive motor to the fixing rod.

[0016] Preferably, the side wall of the guide block is fastened with anti-wear balls; the anti-wear balls are provided at both the top and bottom of the guide block; during operation, when the guide block slides inside the guide groove, the anti-wear balls contact the side wall of the guide groove, which can change the sliding friction between the guide block and the guide groove into rolling friction, thereby reducing the wear between the guide block and the guide groove.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The tunnel gas concentration real-time monitoring device of the present invention, by starting the drive motor, causes the drive motor to drive the rotating sprocket to rotate, which in turn drives the transmission chain to rotate, causing the push block to push the deflection plate, which in turn causes the sliding block to slide. This allows the sliding block to slide back and forth inside the sliding frame. This structural design enables the gas detector to slide back and forth, thereby increasing the monitoring range of the gas detector. It effectively solves the problem that fixing the gas detector in one place when monitoring gas concentration in the present invention easily leads to a small monitoring range.

[0019] 2. The tunnel gas concentration real-time monitoring device of the present invention, by fixing a shield plate to the side wall of the sliding frame to shield the gas detector, and then setting cleaning bristles inside the shield plate to clean the surface of the gas detector, achieves the function of protecting the gas detector and making the surface of the gas detector cleaner at the same time.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1

[0033] like Figures 1 to 4As shown in the embodiment of the present invention, a real-time monitoring device for tunnel gas concentration includes a sliding frame 1; a drive motor 2 is fixedly connected to the side wall of the sliding frame 1; a fixing collar is fixedly connected to the side wall of the drive motor 2, and a fixing rod 3 is fixedly connected between the fixing collar and the side wall of the sliding frame 1; a rotating sprocket 4 is fixedly connected to the output end of the drive motor 2; a rotating sprocket 4 is rotatably connected to the end of the sliding frame 1 away from the rotating sprocket 4; a transmission chain 5 is connected between the two rotating sprockets 4; a sliding block 6 is slidably connected inside the sliding frame 1; the sliding block 6 is sleeved on the outside of the transmission chain 5; a pushing block 7 is fixedly connected to the transmission chain 5; the sliding block... The sliding block 6 is internally rotatably connected to a deflector plate 8; a block protrudes from the end of the deflector plate 8 at the position corresponding to the push block 7; a spring 9 is fixed between the bottom of the deflector plate 8 and the side wall of the sliding block 6; the top and bottom of the sliding block 6 are both provided with deflector plates 8, arranged in a circular array; push teeth 11 are fixedly connected to the end side wall of the sliding frame 1, also arranged in a circular array; a push tooth groove 10 is opened at the position of the push tooth 11 on the sliding block 6; a connecting block 12 is fixedly connected to the side wall of the sliding block 6; a mounting block 13 is fixedly connected to the side wall of the connecting block 12; a gas detector is installed on the side wall of the mounting block 13; during operation, when it is necessary to inspect the tunnel... When monitoring the internal gas concentration, the drive motor 2 can be started, causing the drive motor 2 to drive the rotating sprocket 4 to rotate, which in turn drives the transmission chain 5 to rotate. During the rotation of the transmission chain 5, the push block 7 can be moved. When the push block 7 moves to the position of the bottom deflection plate 8, it will contact the deflection plate 8, thereby pushing the sliding block 6 to slide inside the sliding frame 1. When the sliding block 6 moves to the end position of the sliding frame 1, the push tooth 11 will enter the interior of the push tooth groove 10, thereby pushing the deflection plate 8 to deflect, so that the push block 7 can pass through the deflection plate 8. Then, when the push block 7 rotates along the rotating sprocket 4 to the top position, it will push the top deflection plate 8. The rotating plate 8 causes the sliding block 6 to slide in the opposite direction, which drives the pushing block 7 to move via the transmission chain 5. This pushes the pushing block 7 against the deflecting plate 8, allowing the sliding block 6 to slide back and forth inside the sliding frame 1. This allows the sliding block 6 to move the gas detector, thus increasing the detection range of gas concentration inside the tunnel. At the same time, the lengths of the sliding frame 1 and the transmission chain 5 can be adaptively adjusted according to the usage scenario. When the gas detector detects an abnormal gas concentration, it converts the gas concentration detected by the sensor into an electrical signal, which is then transmitted to the controller. When the gas concentration exceeds the alarm point of the controller, the alarm will sound to remind the operator.

[0034] like Figure 1As shown, a baffle plate 14 is fixedly connected to the side wall of the sliding frame 1; the baffle plate 14 is set at the position corresponding to the mounting block 13; during operation, when the sliding frame 1 is placed inside the tunnel, the baffle plate 14 can effectively prevent falling rocks and other debris on the top or side wall of the tunnel from hitting the surface of the gas detector and causing damage to the gas detector.

[0035] like Figure 4 As shown, a first magnetic block 15 is fixedly connected to the bottom of the pushing block 7; a second magnetic block 16 is fixedly connected to the protruding block of the deflection plate 8; the first magnetic block 15 and the second magnetic block 16 are arranged in a corresponding manner; during operation, when the pushing block 7 contacts the deflection plate 8, the first magnetic block 15 will attract the second magnetic block 16, thereby increasing the friction between the pushing block 7 and the deflection plate 8 when the pushing block 7 pushes the deflection plate 8, thus making the pushing block 7 push the deflection plate 8 more effectively.

[0036] like Figure 5 As shown, the rotating sprocket 4 has an oil storage chamber 401 inside; the rotating sprocket 4 has several oil outlet pipes 402 inside, arranged in a circular pattern; the oil outlet pipes 402 connect the oil storage chamber 401 to the outside, and the ends of the oil outlet pipes 402 are located near the boundary of the rotating sprocket 4; a baffle plate 403 is rotatably connected to the side wall of the rotating sprocket 4 via a torsion spring; the side wall of the baffle plate 403 is in contact with the side wall of the transmission chain 5; the baffle plate 403 is located at the corresponding end of the oil outlet pipe 402; an oil injection pipe 404 is provided between the oil storage chamber 401 and the outside, and a sealing plug is detachably installed at the end of the oil injection pipe 404; during operation, as the rotating sprocket 4 rotates, it drives the transmission chain 5 to rotate, when the rotation... When the lack of lubricating oil between the rotating sprocket 4 and the transmission chain 5 results in high friction between them, the friction will cause the baffle plate 403 to deflect. This allows the lubricating oil inside the oil storage chamber 401 to flow out through the oil outlet pipe 402, thus lubricating the rotating sprocket 4 and the transmission chain 5. At the same time, when there is too much lubricating oil on the transmission chain 5, it may flow into the position of the push block 7. The arc-shaped arrangement of the push block 7 and the second magnetic block 16 allows the lubricating oil to flow down, reducing the amount of lubricating oil on the push block 7 and decreasing the impact of lubricating oil between the push block 7 and the deflection plate 8. This reduces the friction between the push block 7 and the deflection plate 8. Meanwhile, the lubricating oil can flow down through the second magnetic block 16, thus lubricating the side wall between the deflection plates 8 and 6.

[0037] like Figure 1 and Figure 7As shown, the bottom of the shield 14 is provided with a number of cleaning bristles 19; during operation, when the gas detector slides back and forth, the cleaning bristles 19 can come into contact with the surface of the gas detector, thereby cleaning the surface of the gas detector and making the surface of the gas detector cleaner.

[0038] like Figure 7 As shown, the sliding frame 1 has an internal cavity; a synchronous belt 20 is installed inside the cavity and is supported by a rotating column; the ends of the synchronous belt 20 are respectively fixed to the two side walls of the mounting block 13; several rotating shafts 21 are rotatably connected inside the sliding frame 1 and are arranged in a regular pattern; a rotating disk 22 is fixed to the end of each rotating shaft 21; the rotating disk 22 is positioned at the corresponding gas detector position; the cleaning bristles 19 are fixed to the side wall of the rotating disk 22; the top of the synchronous belt 20 is located on the rotating shaft 21. At the bottom position of 1; during operation, when the mounting block 13 slides back and forth, the mounting block 13 can drive the synchronous belt 20 to rotate, which in turn can drive the rotating shaft 21 to rotate, so that when the rotating shaft 21 cleans the surface of the gas detector, the cleaning effect of the gas detector is better, and the surface of the gas detector is cleaner. At the same time, when the mounting block 13 is set, a groove can be opened at the bottom of the baffle plate 14, and the mounting block 13 can be placed inside the groove. The groove restricts the mounting block 13, which makes the sliding of the mounting block 13 more stable.

[0039] like Figures 6 to 8 As shown, positioning blocks 18 are fixedly connected to both the top and bottom of the sliding block 6; the positioning blocks 18 are T-shaped; positioning grooves 17 are provided on the top and bottom sidewalls of the sliding frame 1 at positions corresponding to the positioning blocks 18; guide blocks 23 are fixedly connected to the sidewall of the mounting block 13; guide grooves are provided inside the baffle plate 14; the guide blocks 23 are correspondingly arranged with the guide grooves; during operation, when the sliding block 6 slides inside the sliding frame 1, the positioning grooves 17 restrict the positioning blocks 18, which reduces the likelihood of tilting or deflection of the sliding block 6, thus making the sliding of the sliding block 6 more stable. When the mounting block 13 slides inside the baffle plate 14, the guide grooves restrict the guide blocks 23, which makes the sliding of the mounting block 13 more stable.

[0040] like Figure 6As shown, the inside of the pushing tooth 11 is rotatably connected to an anti-wear roller 24; the anti-wear roller 24 is positioned at the corresponding deflection plate 8; during operation, when the pushing tooth 11 extends into the inside of the pushing tooth groove 10 and thus supports the deflection plate 8, the anti-wear roller 24 can change the sliding friction between the pushing tooth 11 and the deflection plate 8 into rolling friction, thereby reducing the frictional force between the pushing tooth 11 and the deflection plate 8 and reducing the wear between the pushing tooth 11 and the deflection plate 8.

[0041] like Figures 1 to 2 As shown, the fixing rod 3 is set at an angle, and the angle is opposite to the rotation direction of the drive motor 2. During operation, when the fixing rod 3 supports the drive motor 2, the angled fixing rod 3 can make the supporting force between the fixing rod 3 and the drive motor 2 greater, thereby making the support effect of the drive motor 2 on the fixing rod 3 better.

[0042] Example 2

[0043] like Figure 9 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the side wall of the guide block 23 is fastened with anti-wear balls 25; the anti-wear balls 25 are provided at both the top and bottom of the guide block 23; during operation, when the guide block 23 slides inside the guide groove, the anti-wear balls 25 contact the side wall of the guide groove, which can change the sliding friction between the guide block 23 and the guide groove into rolling friction, thereby reducing the wear between the guide block 23 and the guide groove.

[0044] During operation, when monitoring the gas concentration inside the tunnel is required, the drive motor 2 can be started, causing the rotating sprocket 4 to rotate. This, in turn, causes the transmission chain 5 to rotate. As the transmission chain 5 rotates, it moves the push block 7. When the push block 7 reaches the bottom deflection plate 8, it contacts the deflection plate 8, thus pushing the sliding block 6 to slide inside the sliding frame 1. When the sliding block 6 reaches the end of the sliding frame 1, the push tooth 11 enters the push tooth groove 10, thus pushing the deflection plate 8 to deflect, allowing the push block 7 to pass through the deflection plate 8. When the push block 7 rotates along the rotating sprocket 4 to the top position, it pushes... The deflector plate 8 at the top moves the sliding block 6 in the opposite direction, which drives the push block 7 to move via the transmission chain 5. This pushes the push block 7 against the deflector plate 8, allowing the sliding block 6 to slide back and forth inside the sliding frame 1. This allows the sliding block 6 to move the gas detector, thus increasing the detection range of gas concentration inside the tunnel. The lengths of the sliding frame 1 and the transmission chain 5 can be adjusted according to the usage scenario. When the gas detector detects an abnormal gas concentration, it converts the gas concentration detected by the sensor into an electrical signal, which is then transmitted to the controller. When the gas concentration exceeds the alarm point of the controller, the alarm will sound to remind the operator.

[0045] When the sliding frame 1 is placed inside the tunnel, the shielding plate 14 can effectively prevent falling rocks and other debris from the top or side walls of the tunnel from hitting the surface of the gas detector and causing damage to it.

[0046] When the push block 7 comes into contact with the deflection plate 8, the first magnetic block 15 will attract the second magnetic block 16, which will increase the friction between the push block 7 and the deflection plate 8 when the push block 7 pushes the deflection plate 8, thus making the push block 7 push the deflection plate 8 more effectively.

[0047] During the rotation of the sprocket 4, which in turn drives the transmission chain 5, if there is a lack of lubricating oil between the sprocket 4 and the transmission chain 5, resulting in high friction, the friction will cause the baffle plate 403 to deflect. This allows the lubricating oil inside the oil storage chamber 401 to flow out through the oil outlet pipe 402, thus lubricating the sprocket 4 and the transmission chain 5. At the same time, if there is too much lubricating oil on the transmission chain 5, the lubricating oil may flow into the position of the push block 7. The arc-shaped arrangement of the push block 7 and the second magnetic block 16 allows the lubricating oil to flow down, reducing the amount of lubricating oil on the push block 7 and decreasing the impact of lubricating oil between the push block 7 and the deflection plate 8, thus reducing the friction between the push block 7 and the deflection plate 8. Meanwhile, the lubricating oil can flow down through the second magnetic block 16, thus lubricating the side wall between the deflection plates 8 and 6.

[0048] As the gas detector slides back and forth, the cleaning bristles 19 can come into contact with the surface of the gas detector, thereby cleaning the surface of the gas detector and making the surface of the gas detector cleaner.

[0049] As the mounting block 13 slides back and forth, it can drive the timing belt 20 to rotate, which in turn drives the rotating shaft 21 to rotate. This makes the surface of the gas detector cleaner when the rotating shaft 21 cleans it. Additionally, when the mounting block 13 is installed, a groove can be cut at the bottom of the baffle plate 14, and the mounting block 13 can be placed inside the groove. The groove restricts the sliding of the mounting block 13, making its sliding more stable.

[0050] When the sliding block 6 slides inside the sliding frame 1, the positioning groove 17 restricts the positioning block 18, which makes the sliding block 6 less prone to tilting or deflection when sliding inside the sliding frame 1, thus making the sliding of the sliding block 6 more stable. When the mounting block 13 slides inside the baffle plate 14, the guide groove restricts the guide block 23, which makes the sliding of the mounting block 13 more stable.

[0051] When the push tooth 11 extends into the push tooth groove 10 and supports the deflection plate 8, the anti-wear roller 24 can change the sliding friction between the push tooth 11 and the deflection plate 8 into rolling friction, thereby reducing the friction between the push tooth 11 and the deflection plate 8 and reducing the wear between the push tooth 11 and the deflection plate 8.

[0052] When the fixing rod 3 supports the drive motor 2, the obliquely set fixing rod 3 can make the supporting force between the fixing rod 3 and the drive motor 2 greater, thereby making the support effect of the drive motor 2 on the fixing rod 3 better.
