Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and in particular to a gas and odor collaborative monitoring device for environmental monitoring. Background Art

[0002] In environmental monitoring, it is necessary to monitor the gases and odors inside the environment in a coordinated manner. Currently, optical methods are mainly used for monitoring, which is different from the traditional monitoring method using workers' sense of smell. The basic principle of optical monitoring is to measure the gas concentration through an optical probe. This method does not require sample preparation and has the advantages of being fast, non-invasive, efficient and dynamic. It is suitable for rapid on-site detection and continuous real-time online analysis. Among them, infrared gas sensors are widely used. Infrared gas sensors mainly include a housing, an infrared light source, an infrared detector and a signal conditioning circuit. The infrared gas sensor is placed in the space to be detected, the infrared light source is started, and the air inside the space to be detected enters the infrared gas sensor through the housing. The corresponding detection operation can be started. The overall operation is simple and the degree of intelligence is high.

[0003] However, in the actual monitoring process, during the long-term monitoring process of the infrared gas sensor, air enters and exits through the outer through holes, and the aperture of the through holes is small, and the through holes are often blocked, which affects the subsequent monitoring effect. When the temperature in the environment changes, certain water droplets will be generated on the inner wall of the outer shell. These water droplets cannot be cleaned in time, which will seriously affect the monitoring effect. When the water droplets rise rapidly in a short period of time, it means that the monitoring environment at this time has changed dramatically, and the staff needs to make timely adjustments. Traditional infrared gas sensors do not have the ability to cope with the above situation. Therefore, a gas and odor collaborative monitoring device for environmental monitoring is provided.

The above operations are all existing technologies and no redundant description is given;

[0032] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7A dredging and cleaning component for the through hole 2 is installed in the shell 1, and the dredging and cleaning component includes a motor 5 fixedly installed in the shell 1, and the output end of the motor 5 is fixedly connected to a reciprocating screw 6, and two groups of moving blocks 7 are slidably connected in the shell 1, and the reciprocating screw 6 runs through one of the moving blocks 7 and is threadedly connected to the moving block 7, and the side walls of the two groups of moving blocks 7 are fixedly connected to multiple groups of control rods 12, and the upper and lower ends of the multiple groups of control rods 12 are fixedly connected to a control plate 8, and the control plate 8 is threadedly sleeved with multiple groups of threaded rods 24, and one end of the multiple groups of threaded rods 24 is rotatably connected to the same moving plate 11, and the side wall of the moving plate 11 is fixedly connected to a first spring 20, and the other end of the multiple groups of threaded rods 24 is fixedly connected to a moving box 21, and a slide plate 26 is slidably connected in the moving box 21, and a second spring 28 is fixedly connected between the slide plate 26 and the moving box 21, and the outer side of the slide plate 26 is fixed A slide bar 27 is connected, a round table 9 is slidably connected to the outer side of the slide bar 27, a sixth spring 50 is fixedly connected between the round table 9 and the slide bar 27, two groups of clamping plates 13 are fixedly connected to the side wall of the control plate 8, a first rotating rod 14 is rotatably connected between the two groups of clamping plates 13, a first gear 15 is fixedly sleeved on the outer side of the first rotating rod 14, a plurality of groups of first racks 16 are fixedly connected in the housing 1, the first gear 15 and the first rack 16 are meshed, a second rotating rod 17 is also rotatably connected between the two groups of clamping plates 13, the second rotating rod 17 and the first rotating rod 14 are transmission-connected through a first pulley assembly 18, a second gear 19 is fixedly sleeved on the outer side of the second rotating rod 17, a first connecting rod 25 is fixedly connected to the outer side of the moving plate 11, a second rack 23 is fixedly connected to the outer side of the first connecting rod 25, the second rack 23 is meshed with the second gear 19;

[0033] During the monitoring process, the motor 5 is started, and the motor 5 drives the reciprocating screw 6 to rotate. Figure 2Based on the direction, since the moving block 7 is connected to the housing 1 for sliding left and right, the rotating reciprocating screw 6 will drive the threaded moving block 7 to move back and forth left and right, and the moving block 7 drives the control plate 8 to move back and forth left and right through the control rod 12. Since the first rack 16 is fixedly installed inside the housing 1, during the process of the control plate 8 moving back and forth left and right as a whole (the principle and function of the control plate 8 moving left or right in this scheme are the same, so the description is based on the movement of the control plate 8 to the right), when the control plate 8 moves to the right, the control plate 8 drives the clamping plate 13 and the first rotating rod 14 to move right, and the first rotating rod 14 drives the first gear 15 to move right. When the first rack 16 and the first gear 15 are meshed, the first gear 15 follows the control During the movement of the plate 8 to the right, the first gear 15 will also rotate counterclockwise, the first gear 15 drives the first rotating rod 14 to rotate counterclockwise, the first rotating rod 14 drives the second rotating rod 17 to rotate counterclockwise through the first pulley assembly 18, the second rotating rod 17 drives the second gear 19 to rotate counterclockwise, the second gear 19 drives the second rack 23 and the first connecting rod 25 to move upward, the first connecting rod 25 drives the moving plate 11 to move upward, and the moving plate 11 compresses the first spring 20 while also driving the threaded rod 24 to move upward. Since the threaded rod 24 is threadedly connected to the control plate 8, the threaded rod 24 will also rotate during the upward movement of the threaded rod 24, and the threaded rod 24 drives the moving box 21 and the round table 9 to move upward as a whole. Self-rotation. During the upward movement of the table 9, the table 9 will first abut against the inner wall of the shell 1. Under the obstruction of the inner wall of the shell 1, the table 9 stops moving upward and compresses the sixth spring 50. However, the table 9 will follow the moving box 21 to move to the right. When the table 9 moves to the lower side of the through hole 2, the table 9 loses the obstruction of the shell 1 and enters the through hole 2. During this process, the table 9 continues to rotate with the moving box 21. After the table 9 enters the through hole 2, the table 9 that moves upward and rotates can clear and clean the inner wall of the through hole 2 to maintain the normal working effect of the through hole 2. After the table 9 moves into the through hole 2, the control board 8 moves to the left as a whole. At this time, the device as a whole repeats the above-mentioned reverse operation, which leads to the moving box 21. 21 moves to the left, and the moving box 21 drives the table 9 to move to the left through the slide plate 26 and the slide bar 27, and the table 9 slides out of the through hole 2. In the above-mentioned cleaning process, the table 9 does not completely enter the through hole, and part of the table 9 is still located on the outside of the through hole 2, that is, in the process of the table 9 entering the through hole 2 and moving out of the through hole 2, the outer conical surface of the table 9 is always against the inner wall of the through hole 2, and the table 9 and the inner wall of the through hole 2 are both smoothly set, which will not hinder the movement of the table 9 and will not cause motion interference. Secondly, after the moving plate 11 loses the power of the second rack 23, it will return to its original position relative to the control plate 8 under the action of the first spring 20, and the threaded rod 24 and the control plate 8 will not form a self-locking phenomenon, that is, the thread lead angle is greater than the friction angle.

[0034] like Figure 8 , Fig. 9 , Fig.11 , a cleaning assembly for the inner wall of the shell 1 is installed on the outer side of the control panel 8, and the cleaning assembly includes multiple groups of fixed plates 29 fixedly installed on the outer side of the control panel 8, and the multiple groups of fixed plates 29 are staggered. A third connecting rod 39 is rotatably connected in the multiple groups of fixed plates 29, and the multiple groups of fixed plates 29 are rotatably connected to the same transmission rod 22. The transmission rod 22 is transmission-connected to the third connecting rod 39 through a second pulley assembly 40, and the two ends of the transmission rod 22 are fixedly connected to a third gear 30. Multiple groups of third racks 31 are fixedly connected to the inner wall of the shell 1, and the third racks 31 are meshed with the third gear 30. Two groups of square rods 45 are symmetrically fixedly connected to the outer side of the third connecting rod 39, and sleeves 48 are slidably sleeved on the outer sides of the two groups of square rods 45. A fourth spring 47 is fixedly connected between the sleeve 48 and the square rod 45, and a cleaning plate 10 is slidably connected to the outer side of the sleeve 48, and a fifth spring 49 is fixedly connected between the cleaning plate 10 and the sleeve 48;

[0035] First, a towel is fixedly sleeved on the outer side of the cleaning plate 10, and the towel is used to clean the water drops on the inner wall of the shell 1. Secondly, when the control plate 8 moves to the right, the control plate 8 drives the fixed plate 29, the third connecting rod 39 and the transmission rod 22 to move. When the third gear 30 and the third rack 31 are meshed, the transmission rod 22 will rotate relative to the control plate 8. The transmission rod 22 drives the third connecting rod 39 to rotate through the second pulley assembly 40. The third connecting rod 39 drives the cleaning plate 10 to rotate around the third connecting rod 39 through the square rod 45, the sleeve 48 and the fifth spring 49. When one of the cleaning plates 10 is against the inner wall of the shell 1, the third gear 30 and the third rack 31 are just disconnected. Among them, when the cleaning plate 10 is against the inner wall of the shell 1, the fourth spring 47 is in a compressed state, and then Fig.11 Based on the direction of the square rod 45 and the sleeve 48 are connected for vertical sliding, and the sleeve 48 and the cleaning plate 10 are connected for horizontal sliding.

[0036] A sensor is also fixedly connected between the square rod 45 and the sleeve 48. First, the sensor is a tension sensor, which can detect both pressure and tension. When the cleaning plate 10 and the outer shell 1 are against each other, the sensor will be compressed, and the sensor will send out a corresponding electrical signal. When the cleaning plate 10 moves to the lower side of the third connecting rod 39, at this time, the cleaning plate 10 is only subject to its own gravity and the elastic force of the fourth spring 47. However, this cleaning plate 10 has just cleaned the inner wall of the outer shell 1. If there are many water droplets on the inner wall of the outer shell 1, the water droplets remaining on the cleaning plate 10 will cause the cleaning plate 10 to become heavier, and then cause the electrical signal sent by the sensor to change. The staff can calculate the amount of water droplets in the outer shell 1 according to the size of the electrical signal generated by the sensor. If the water droplet content is too much, it will cause a large error in the monitoring effect, and timely adjustment is required.

[0037] like Figure 8 The outer side of the transmission rod 22 is fixedly sleeved with a rotating plate 32, and four groups of slots 33 are opened on the outer side of the rotating plate 32 in the circumferential direction. The outer side of the control plate 8 is slidably connected with a moving frame 35, and the outer side of the moving frame 35 is fixedly connected with a second connecting rod 36, and the outer side of the second connecting rod 36 is fixedly connected with a fourth rack 37, and the fourth rack 37 is meshed with the first gear 15. The outer side of the moving frame 35 is also fixedly connected with a clamping rod 34, and one end of the clamping rod 34 extends to the clamping groove 33 and abuts against the bottom of the clamping groove 33;

[0038] First, when the first rack 16 is not meshed with the first gear 15, the third rack 31 is also not meshed with the third gear 30, and the length of the first rack 16 is greater than the length of the third rack 31. When the first rack 16 is just meshed with the first gear 15, the third rack 31 and the third gear 30 are not yet meshed. During this process, the first gear 15 drives the fourth rack 37 to move, and the fourth rack 37 moves through the second connecting rod 36 and the moving frame 35. The moving frame 35 drives the clamping rod 34 to move. When the clamping rod 34 is just moved out of the clamping slot 33, the third rack 31 is just meshed with the third gear 30. At this time, the rotating plate 32 loses the limit of the clamping rod 34. The rotating plate 32 and the transmission rod 22 start to rotate, that is, the cleaning plate 10 for cleaning the inner wall of the shell 1 starts to be switched. When it is replaced with another cleaning plate 10, that is, after the third connecting rod 39 rotates half a circle, the third rack 31 and the third gear 30 are disconnected, and the first rack 16 is just disconnected from the first gear 15. At this time, under the action of the first spring 20, the moving plate 11 quickly returns to its original position relative to the control plate 8, thereby causing the clamping rod 34 to quickly enter the clamping groove 33, clamping the rotating plate 32 and the transmission rod 22, and the cleaning plate 10 starts to clean the inner wall of the shell 1. The overall operation is automatically performed to ensure the cleaning effect of the inner wall of the shell 1.

[0039] like Fig. 9 , Fig.10The outer side of the control plate 8 is also slidably connected with a sawtooth plate 38, the sawtooth plate 38 is located between the control plate 8 and the cleaning plate 10, the side wall of the sawtooth plate 38 is fixedly connected with a connecting plate 43, a third spring 44 is fixedly connected between the connecting plate 43 and the control plate 8, the outer side of the connecting plate 43 is fixedly connected with a sawtooth bar 41, the outer side of the moving plate 11 is fixedly connected with a protrusion 42, the protrusion 42 and the sawtooth bar 41 are abutted, and the outer sides of the protrusion 42 and the sawtooth bar 41 are both smoothly arranged;

[0040] First, when the control board 8 moves back and forth, the movable board 11 will move up and down relative to the control board 8. When the movable board 11 moves up and down, the protrusion 42 and the sawtooth bar 41 abut against each other. Since the sawtooth bar 41 and the connecting plate 43 are fixedly connected, and the fixed plate 29 and the control board 8 are slidably connected to each other (with the movable board 11 moving up and down), the protrusion 42 and the sawtooth bar 41 abut against each other. Fig.10 The direction is based on the movement of the sawtooth plate 38, therefore, the movable plate 11 moving up and down will drive the sawtooth bar 41 and the connecting plate 43 to slide left and right relative to the control plate 8, and the connecting plate 43 drives the sawtooth plate 38 to move left and right. After the cleaning plate 10 completes the cleaning operation of the inner wall of the shell 1, if there are more water droplets on the outside of the cleaning plate 10, it will cause the cleaning plate 10 to become heavier, and the cleaning plate 10 moves downward relative to the third connecting rod 39. The cleaning plate 10 and the sawtooth plate 38 are offset. Since the sawtooth plate 38 keeps moving left and right, the sawtooth plate 38 will form a cleaning effect on the cleaning plate 10, clean the water droplets on the outside of the cleaning plate 10, and reduce the water droplets on the outside of the cleaning plate 10, thereby maintaining the overall water absorption effect of the cleaning plate 10.

[0041] In the present invention, the device is installed as a whole in the space to be detected, the air inside the space to be detected enters the housing 1 through the through hole 2, the infrared light source 3 is started, the infrared light emitted by the infrared light source 3 irradiates the receiving board 4, and the corresponding detection operation is started. The above operations are all existing technologies and no redundant description is made;

[0042] During the monitoring process, the motor 5 is started, and the motor 5 drives the reciprocating screw 6 to rotate. Figure 2As the moving block 7 is connected to the housing 1 for sliding movement, the rotating reciprocating screw 6 drives the threaded moving block 7 to move back and forth left and right, and the moving block 7 drives the control plate 8 to move back and forth left and right through the control rod 12. Since the first rack 16 is fixedly installed inside the housing 1, during the overall movement of the control plate 8 back and forth left and right, when the control plate 8 moves to the right, the control plate 8 drives the clamping plate 13 and the first rotating rod 14 to move to the right, and the first rotating rod 14 drives the first gear 15 to move to the right. When the first rack 16 and the first gear 15 are meshed, the first gear 15 follows the control plate 8 to move to the right. 5 will also rotate counterclockwise, the first gear 15 drives the first rotating rod 14 to rotate counterclockwise, the first rotating rod 14 drives the second rotating rod 17 to rotate counterclockwise through the first pulley assembly 18, the second rotating rod 17 drives the second gear 19 to rotate counterclockwise, the second gear 19 drives the second rack 23 and the first connecting rod 25 to move upward, the first connecting rod 25 drives the moving plate 11 to move upward, the moving plate 11 compresses the first spring 20 and also drives the threaded rod 24 to move upward, because the threaded rod 24 is threadedly connected to the control plate 8, so in the process of the threaded rod 24 moving upward, it will also rotate, and the threaded rod 24 drives the moving box 21 and the round The table 9 moves upward as a whole and also rotates. In the process of the table 9 moving upward, the table 9 will first abut against the inner wall of the shell 1. Under the obstruction of the inner wall of the shell 1, the table 9 stops moving upward and compresses the sixth spring 50. However, the table 9 will move to the right with the moving box 21. When the table 9 moves to the lower side of the through hole 2, the table 9 loses the obstruction of the shell 1 and enters the through hole 2. During this process, the table 9 keeps rotating with the moving box 21. After the table 9 enters the through hole 2, the table 9 that moves upward and rotates can clear and clean the inner wall of the through hole 2 to maintain the normal working effect of the through hole 2. After 9 moves into the through hole 2, the control board 8 moves to the left as a whole. At this time, the device as a whole repeats the above-mentioned opposite operation, thereby causing the moving box 21 to move to the left. The moving box 21 drives the round table 9 to move to the left through the slide plate 26 and the slide rod 27, and the round table 9 slides out of the through hole 2. In the above-mentioned cleaning process, the round table 9 does not completely enter the through hole, and part of the round table 9 is still located on the outside of the through hole 2, that is, in the process of the round table 9 entering the through hole 2 and moving out of the through hole 2, the outer conical surface of the round table 9 is always against the inner wall of the through hole 2, and the round table 9 and the inner wall of the through hole 2 are both smoothly set, and will not hinder the movement of the round table 9, and will not cause motion interference;

[0043] When the first rack 16 just meshes with the first gear 15, the third rack 31 and the third gear 30 are not yet meshed. During this process, the first gear 15 drives the fourth rack 37 to move, and the fourth rack 37 moves through the second connecting rod 36 and the moving frame 35. The moving frame 35 drives the clamping rod 34 to move. When the clamping rod 34 just moves out of the clamping groove 33, the third rack 31 just meshes with the third gear 30. At this time, the rotating plate 32 loses the restriction of the clamping rod 34, and the rotating plate 32 and the transmission rod 22 start to rotate, that is, the cleaning mode for cleaning the inner wall of the housing 1 is switched. When the cleaning plate 10 is replaced with another cleaning plate 10, that is, after the third connecting rod 39 rotates half a circle, the third rack 31 and the third gear 30 are disconnected, and the first rack 16 is just disconnected from the first gear 15. At this time, under the action of the first spring 20, the moving plate 11 quickly returns to its original position relative to the control plate 8, thereby causing the clamping rod 34 to quickly enter the clamping groove 33, clamping the rotating plate 32 and the transmission rod 22, and the cleaning plate 10 starts to clean the inner wall of the housing 1. The overall operation is automatically performed to ensure the cleaning effect of the inner wall of the housing 1;

[0044] When the cleaning plate 10 and the housing 1 are against each other, the sensor will be compressed and the sensor will send out a corresponding electrical signal. When the cleaning plate 10 moves to the lower side of the third connecting rod 39, at this time, the cleaning plate 10 is only subject to its own gravity and the elastic force of the fourth spring 47. However, the cleaning plate 10 has just cleaned the inner wall of the housing 1. If there are many water droplets on the inner wall of the housing 1, the water droplets will remain on the cleaning plate 10, which will cause the cleaning plate 10 to become heavier, thereby causing the electrical signal sent by the sensor to change. The staff can calculate the amount of water droplets in the housing 1 according to the size of the electrical signal generated by the sensor. If the water droplet content is too much, it will cause a large error in the monitoring effect, and timely adjustment is required;

[0045] When the moving plate 11 moves up and down, the protrusion 42 and the sawtooth bar 41 are against each other. Since the sawtooth bar 41 and the connecting plate 43 are fixedly connected, and the fixed plate 29 and the control plate 8 are slidably connected to each other left and right (with Fig.10 The direction is based on the movement of the sawtooth plate 38, therefore, the movable plate 11 moving up and down will drive the sawtooth bar 41 and the connecting plate 43 to slide left and right relative to the control plate 8, and the connecting plate 43 drives the sawtooth plate 38 to move left and right. After the cleaning plate 10 completes the cleaning operation of the inner wall of the shell 1, if there are more water droplets on the outside of the cleaning plate 10, it will cause the cleaning plate 10 to become heavier, and the cleaning plate 10 moves downward relative to the third connecting rod 39. The cleaning plate 10 and the sawtooth plate 38 are offset. Since the sawtooth plate 38 keeps moving left and right, the sawtooth plate 38 will form a cleaning effect on the cleaning plate 10, clean the water droplets on the outside of the cleaning plate 10, and reduce the water droplets on the outside of the cleaning plate 10, thereby maintaining the overall water absorption effect of the cleaning plate 10.
