Description

Technical Field

[0001] The present invention relates to the technical field of air pollution monitoring, and in particular to an air pollution monitoring and early warning device. Background Art

[0002] Air pollution monitoring and early warning devices are instruments and systems used to monitor the concentrations of various pollutants, meteorological parameters and air quality in the atmospheric environment in real time and continuously, and to issue early warning signals when necessary.

[0003] After searching, the Chinese patent with the announcement number CN211627293U discloses an air pollution monitoring device, including a chassis, an electric lifting rod is fixedly installed at the middle position of the upper end of the chassis, a lightning rod is fixedly installed at the top of the electric lifting rod, a photovoltaic panel is fixedly installed at the front side of the electric lifting rod and near the position below the lightning rod, a rod sleeve is fixedly sleeved at the outer side of the electric lifting rod and near the position below the photovoltaic panel, a connecting rod is fixedly connected to one side of the rod sleeve, a supporting plate is fixedly connected to the end of the connecting rod away from the rod sleeve, and a wind vane is fixedly installed at the left position of the upper end of the supporting plate. The above scheme arranges the air pollution monitor inside the gas collecting box, which can effectively protect the air pollution monitor, and drives the gas collecting box to rotate by the first motor, so that the box opening of the gas collecting box is always aligned with the direction of the headwind, which can effectively collect the atmosphere, thereby enhancing the reliability of the monitoring data. However, the above scheme still has the following shortcomings when it is actually used:

[0057] As a further solution of the present invention: the flow limiting directions of the two one-way valves are opposite.

[0058] Beneficial effects of the present invention:

[0059] 1. This design realizes the automatic rotation and adjustment function of the photovoltaic panel through the mechanical structure. The clever coordination of the rotating block and the moving block, as well as the synergistic effect of the elastic bag and the one-way valve, enable the pneumatic part to continuously supply air to the air bag during the rotation process, thereby driving the photovoltaic panel to rotate. When the photovoltaic panel rotates to the position in contact with the top of the limit rod, it will automatically adjust to a horizontal state, thereby significantly reducing the wind-receiving area and the wind resistance of the overall device. Compared with the traditional fixed structure, this rotatable photovoltaic panel can automatically adjust its posture when the wind blows, effectively improving the stability of the rod body in a windy environment;

[0060] 2. The design of opening an exhaust port on the airbag allows the gas inside the airbag to be slowly discharged through the exhaust port when the wind stops, the pneumatic parts stop rotating, and the elastic bag no longer supplies air to the airbag, so that the photovoltaic panel can be slowly reset under the action of gravity. This design ensures that the photovoltaic panel can return to the best light receiving angle when the wind stops, maximizes its light receiving area, and thus improves power generation efficiency;

[0061] 3. Through the trigger mechanism, the intelligent rotation control of the photovoltaic panel under wind conditions is realized. When the wind force is small, the rotation speed of the pneumatic parts is slow, the centrifugal force on the slider is small, and a certain distance is maintained between the movable card plate and the fixed card plate, avoiding unnecessary contact and rotation, thereby ensuring that the photovoltaic panel remains stationary under breeze conditions and can stably receive sunlight for power generation, thereby ensuring power generation efficiency. When the wind force increases to a certain extent, the rotation speed of the pneumatic parts is accelerated, the centrifugal force of the slider increases, the movable card plate contacts the fixed card plate and triggers the rotation mechanism. At this time, the rotating ring will drive the rotating block to rotate, and then the photovoltaic panel will rotate through the top action of the airbag, reducing the wind-receiving area and improving the stability of the device in strong wind environments. This design not only improves the power generation efficiency of the photovoltaic panel under breeze conditions, but also ensures the safety and stability of the device under strong wind conditions, realizing the perfect combination of intelligent regulation and efficient power generation;

[0062] 4. The design realizes the automatic dust cleaning function during the rotation of the photovoltaic panel through the dust cleaning structure. Whenever the photovoltaic panel rotates, the cleaning plate will be pulled upward through the linkage of the pull rope. During the movement of the cleaning plate, the two guide blocks and the two guide rods play a good limiting role, ensuring that the cleaning plate can move stably and accurately. The bristles on the cleaning plate will brush the dust baffle when moving, effectively brush off the dust attached to the dust baffle, and transfer the dust to the bristles. Through timely dust cleaning, the dust baffle is avoided from being blocked, thereby ensuring the normal operation and monitoring effect of the photovoltaic panel and the associated atmospheric monitoring equipment;

[0063] 5. By introducing the innovative structure of comb teeth and sealing capsules, the automatic cleaning function of the cleaning plate bristles is realized, further improving the efficiency and effect of the cleaning system. When the cleaning plate moves to the upper limit position, the bristles pass through the comb teeth, and the comb teeth can scrape off the dust attached to the bristles, effectively avoiding the influence of dust accumulation on the cleaning ability of the bristles. At the same time, when the cleaning plate moves up, the moving block is driven up by the connecting plate, and the sealing capsule is stretched to perform air extraction, preparing for subsequent jet cleaning. When the photovoltaic panel is reversed and reset, the cleaning plate moves down and resets under the action of gravity, and the moving block is also reset and squeezes the sealing capsule. The gas in the sealing capsule is pressed into the dust removal pipe and sprayed out through the pipe mouth, blowing directly to the comb teeth to blow away the dust attached to the comb teeth. This design not only ensures the cleanliness of the bristles, and then ensures the cleaning effect of the bristles on the dustproof partition, but also realizes the automatic cleaning of the comb teeth, avoiding the circulation and accumulation of dust in the system.

DETAILED DESCRIPTION

[0078] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0079] like Figure 1-12 As shown, an air pollution monitoring and early warning device includes a pole body 11, an air monitoring component and a photovoltaic power supply component: wherein the air monitoring component includes an air pollution monitoring device 21, an air inlet 22 and a dustproof baffle 23, the air pollution monitoring device 21 is installed on the pole body 11, the air inlet 22 is opened on the air pollution monitoring device 21, the dustproof baffle 23 is fixed in the air inlet 22, and a plurality of holes are opened on the dustproof baffle 23;

[0080] The photovoltaic power supply assembly is arranged at the top of the rod body 11, and the photovoltaic power supply assembly includes a rotatable photovoltaic power generation panel 34. The photovoltaic power generation assembly also includes: a fixed frame 31, fixed to the top of the rod body 11; a fixed seat 32, fixed on the fixed frame 31; a rotating seat 33, rotatably assembled on the fixed seat 32, and the photovoltaic power generation panel 34 is installed on the rotating seat 33; a limit rod 35, fixed on the fixed frame 31;

[0081] The rod body 11 is provided with a lifting structure, which acts on the photovoltaic power generation panel 34. The lifting structure includes: a bracket 41, which is fixed on the fixing frame 31; an air bag 42, which is fixed on the end of the bracket 41 away from the fixing frame 31, and the end of the air bag 42 away from the bracket 41 is connected to the photovoltaic power generation panel 34; an exhaust port 43 is provided on the air bag 42, and when the air bag 42 is inflated, it can lift up the photovoltaic power generation panel 34, so that the photovoltaic power generation panel 34 rotates. A limiter for providing a limit to the photovoltaic power generation panel 34 is fixed on the fixing frame 31. Rod 35, when the photovoltaic power generation panel 34 rotates to a position in contact with the top end of the limit rod 35, the photovoltaic power generation panel 34 is just in a horizontal state. In this case, the wind-receiving surface of the photovoltaic power generation panel 34 in the horizontal state will be greatly reduced, thereby reducing the wind resistance of the photovoltaic power generation panel 34 to the entire device. The rotatable photovoltaic power generation panel 34 replaces the traditional fixed structure. When the wind blows, the photovoltaic power generation panel 34 can automatically rotate to reduce the wind-receiving area of ​​the photovoltaic power generation panel 34 and improve the stability of the rod body 11 in a windy environment;

[0082] An air supply structure is provided on the rod body 11, which is arranged at the top of the rod body 11. The air supply structure is used to supply air to the lifting structure. The air supply structure is composed of a driving part, a triggering part and an air supply part. The driving part includes: an outer cylinder 50 fixed at the top of the rod body 11; an inner cylinder 51 fixed inside the outer cylinder 50; a pneumatic part 52 arranged on the top surface of the outer cylinder 50; a rotating shaft 53 fixedly connected to the pneumatic part 52. The triggering part includes: a rotating ring 60 rotatably installed inside the outer cylinder 50; a rotating disk 61 fixedly sleeved on the rotating shaft 53, and the rotating disk 61 is located inside the rotating ring 60; two side plates 62 both fixed on the top surface of the rotating disk 61; a sliding rod 63 fixed between the two side plates 62; a slider 64 slidably sleeved on the sliding rod 63; a spring 65 with one end connected to the slider 64 and the other end connected to one of the side plates 62; a movable clamping plate 66 fixed on the slider 64; a fixed clamping plate 67 fixed on the inner ring of the rotating ring 60. The air supply part includes: a rotating block 71 rotatably installed inside the inner cylinder 51, and the rotating block 71 is fixedly connected to the rotating ring 60; a moving block 72 slidably arranged inside the inner cylinder 51 and arranged opposite to the rotating block 71; a limiting groove 73 opened on the inner surface of the inner cylinder 51; a limiting block 74 fixed on the moving block 72, and the limiting block 74 is slidably arranged in the limiting groove 73; an elastic bladder 75 with one end connected to the inner bottom surface of the inner cylinder 51 and the other end connected to the moving block 72; two air pipes 76 with one end of each connected to the elastic bladder 75, and the other end of one of the air pipes 76 is connected to the air bladder 42; two one-way valves 77 respectively installed on the two air pipes 76, and the flow-limiting directions of the two one-way valves 77 are opposite. One of the one-way valves 77 limits the gas to only enter the inside of the elastic bladder 75, and the other one-way valve 77 limits the gas to only flow out of the elastic bladder 75. Therefore, when the elastic bladder 75 is squeezed, the gas in the elastic bladder 75 will be pressed into the air bladder 42. When the elastic bladder 75 returns to its original state, the elastic bladder 75 can extract the gas from the external environment. Based on the above process, along with the rotation of the pneumatic part 52, the elastic bladder 75 can continuously supply air to the air bladder 42, making the air bladder 42 continuously inflate and expand;

[0083] For the triggering part, when the wind force is small, the rotation speed of the pneumatic part 52 is slow, and the centrifugal force received by the slider 64 is also small. This makes the distance between the movable clamping plate 66 and the fixed clamping plate 67 far, that is, the movable clamping plate 66 will not contact the fixed clamping plate 67 during rotation. Therefore, when the wind force is small, the rotating ring 60 will not drive the rotating block 71 to rotate, and the photovoltaic panel 34 will not rotate automatically. Only when the wind force is large, the photovoltaic panel 34 will rotate under the lifting action of the air bladder 42. This design can ensure the power generation efficiency of the photovoltaic panel 34;

[0084] The air pollution monitoring device 21 is provided with a dust cleaning structure, which includes: a cleaning plate 81, which is arranged on the side of the air pollution monitoring device 21, and the cleaning plate 81 is arranged opposite to the air inlet 22; two guide blocks 82, which are respectively fixed at both ends of the cleaning plate 81; two guide rods 83, which are both fixed on the side of the air pollution monitoring device 21, and the two guide blocks 82 are respectively slidably sleeved on the two guide rods 83; bristles 84, which are arranged on the side of the cleaning plate 81, and the bristles 84 are in contact with the air pollution monitoring device 21; a pull rope 85, one end of which is connected to the cleaning plate 81, and the other end is connected to the photovoltaic power generation panel 34, and whenever the photovoltaic power generation panel 34 is When the rotation occurs, the photovoltaic panels 34 can pull the cleaning plate 81 through the pull rope 85, so that the cleaning plate 81 moves upward. During the movement of the cleaning plate 81, the two guide blocks 82 and the two guide rods 83 limit the movement of the cleaning plate 81. During the movement of the cleaning plate 81, the bristles 84 thereon can brush the dustproof partition 23 and brush off the dust attached to the dustproof partition 23, so that the dust adheres to the bristles 84. This design can clean the dust attached to the dustproof partition 23, avoid the dust from clogging the dustproof partition 23, and ensure the monitoring effect of the air pollution monitoring device 21 on the atmosphere.

[0085] A comb tooth 9 is fixed on the side of the air pollution monitoring device 21, and the comb tooth 9 is located just above the cleaning plate 81. The bristles 84 on the cleaning plate 81 will pass through the comb teeth 9, and at this time the comb teeth 9 can scrape off the dust attached to the bristles 84, that is, the dust will be transferred from the bristles 84 to the comb teeth 9. A blowing structure is also provided on the side of the air pollution monitoring device 21, and the blowing structure includes: a fixed cylinder 101, fixed on the side of the air pollution monitoring device 21; a slideway 102, opened on the outer surface of the fixed cylinder 101, and the slideway 102 is arranged along the height direction of the fixed cylinder 101; a lifting block 103, slidably arranged in the fixed cylinder 101, and the outer surface of the lifting block 103 and the inner surface of the fixed cylinder 101 are in contact with each other; a connecting plate 104, one end of which is fixedly connected to the cleaning plate 81, and the other end is fixedly connected to the lifting block 103, The connecting plate 104 is slidably arranged in the slideway 102; the sealing bag 105 is connected to the inner bottom surface of the fixed cylinder 101 at one end, and is connected to the lifting block 103 at the other end; the dust removal pipe 106 is fixed on the side of the atmospheric pollution monitoring equipment 21, and the dust removal pipe 106 is arranged opposite to the comb teeth 9. The dust removal pipe 106 and the sealing bag 105 are connected by a hose. When the sealing bag 105 is squeezed, the gas in the sealing bag 105 will be pressed into the dust removal pipe 106 and ejected through the dust removal pipe 106. The mouth of the dust removal pipe 106 is arranged toward the comb teeth 9. When the gas is ejected through the dust removal pipe 106, the gas can blow away the dust attached to the comb teeth 9, thereby cleaning the dust on the comb teeth 9. This design can ensure the cleanliness of the bristles 84, and then ensure the cleaning effect of the bristles 84 on the dustproof partition 23.

[0086] Working principle of the present invention:

[0087] When the air pollution monitoring and early warning device proposed by the present invention is in use, in the initial state, the photovoltaic panel 34 is in a tilted state. At this time, the photovoltaic panel 34 has a larger light-receiving area and continuously supplies power to the air pollution monitoring device 21. When the wind blows, the pneumatic member 52 will rotate under the action of the wind. The pneumatic member 52 includes an end cap, four connecting rods and four wind cups. The end cap is fixed to the top of the rotating shaft 53, and the four connecting rods are all fixed to the end cap. The four wind cups are respectively fixed to the ends of the four connecting rods away from the end cap. When the wind blows, the four wind cups will rotate under the action of the wind. The end cap is driven to rotate. When the end cap rotates, the rotating shaft 53 can be driven to rotate, and the rotating disk 61 sleeved on the rotating shaft 53 will also rotate accordingly. In this process, the slider 64 will overcome the elastic force of the spring 65 under the action of centrifugal force and slide toward the edge of the rotating disk 61, and drive the movable clamping plate 66 to move. When the movable clamping plate 66 moves toward the edge of the rotating disk 61, the movable clamping plate 66 can contact with the fixed clamping plate 67 during the rotation process, and drive the fixed clamping plate 67 to rotate. When the fixed clamping plate 67 rotates, it drives the rotating ring 60 to rotate, so that the rotating ring 60 drives the rotating block 71 to rotate.

[0088] Since the rotating block 71 and the moving block 72 form a cylindrical structure together, the rotating block 71 and the moving block 72 are of the same size, and the opposite ends of the rotating block 71 and the moving block 72 are provided with inclined surfaces, and the outer edges of the rotating block 71 and the moving block 72 are in contact with the inner surface of the inner cylinder 51. Therefore, during the rotation of the rotating block 71, the inclined surface portion can squeeze the inclined surface portion of the moving block 72. Under the limiting action of the limiting groove 73 and the limiting block 74, the moving block 72 cannot rotate with the rotating block 71, so the moving block 72 will rotate during the rotation. The movable block 71 moves under the squeezing action of the rotating block 71, so when the rotating block 71 squeezes the movable block 72, the movable block 72 moves downward and squeezes the elastic bag 75. On the contrary, when the rotating block 71 does not squeeze the movable block 72, the movable block 72 moves upward and resets under the elastic force of the elastic bag 75, so that the elastic bag 75 is continuously squeezed and restored. Further, the limiting directions of the two one-way valves 77 are opposite. Specifically, one of the one-way valves 77 limits the gas to only enter the interior of the elastic bag 75, and the other one-way valve 77 limits The gas can only flow out from the elastic bag 75. Therefore, when the elastic bag 75 is squeezed, the gas in the elastic bag 75 will be pressed into the air bag 42. When the elastic bag 75 is restored, the elastic bag 75 can extract gas from the external environment. Based on the above process, along with the rotation of the pneumatic member 52, the elastic bag 75 can continuously supply gas to the air bag 42, so that the air bag 42 is continuously inflated and expanded. When the air bag 42 expands, it can lift up the photovoltaic power generation panel 34, so that the photovoltaic power generation panel 34 rotates. The fixing frame 31 is fixed with a device for lifting the photovoltaic power generation panel 34. A limit rod 35 is provided for limiting position. When the photovoltaic power generation panel 34 rotates to a position in contact with the top of the limit rod 35, the photovoltaic power generation panel 34 is just in a horizontal state. In this case, the wind-receiving surface of the photovoltaic power generation panel 34 in the horizontal state will be greatly reduced, thereby reducing the wind resistance of the photovoltaic power generation panel 34 to the entire device. The rotatable photovoltaic power generation panel 34 replaces the traditional fixed structure. When the wind blows, the photovoltaic power generation panel 34 can automatically rotate to reduce the wind-receiving area of ​​the photovoltaic power generation panel 34 and improve the stability of the rod body 11 in a windy environment;

[0089] For the photovoltaic power generation panel 34, the outer frame of the photovoltaic power generation panel 34 can be made of lightweight materials, the purpose is to reduce the overall weight of the photovoltaic power generation panel 34, so that the airbag 42 can push the photovoltaic power generation panel 34 to rotate. In addition, for the airbag 42, an exhaust port 43 is opened on the airbag 42. When the wind stops, the pneumatic member 52 no longer rotates, and the elastic bag 75 no longer supplies air to the airbag 42. At this time, the gas inside the airbag 42 will be slowly discharged through the exhaust port 43, and the airbag 42 will also be compressed under the gravity of the photovoltaic power generation panel 34, which enables the photovoltaic power generation panel 34 to slowly reset to ensure the light receiving area of ​​the photovoltaic power generation panel 34 when the wind stops. It is worth noting that the diameter of the exhaust port 43 is small enough. When the elastic bag 75 supplies air to the airbag 42, the speed at which the gas enters the airbag 42 is much faster than the speed at which the gas is discharged through the exhaust port 43, thereby ensuring that the airbag 42 can be smoothly inflated.

[0090] For the trigger member, when the wind force is small, the rotation speed of the pneumatic member 52 is slow, and the centrifugal force on the slider 64 is also small, which makes the distance between the movable card plate 66 and the fixed card plate 67 far, that is, the movable card plate 66 will not contact the fixed card plate 67 during the rotation process. Therefore, when the wind force is small, the rotating ring 60 will not drive the rotating block 71 to rotate, and the photovoltaic power generation panel 34 will not rotate automatically. Only when the wind force is large, the photovoltaic power generation panel 34 will rotate under the jacking action of the airbag 42. This design can ensure the power generation efficiency of the photovoltaic power generation panel 34;

[0091] The air pollution monitoring device 21 is also provided with a dust cleaning structure. Whenever the photovoltaic power generation panel 34 rotates, the photovoltaic power generation panel 34 can pull the cleaning plate 81 through the pull rope 85, so that the cleaning plate 81 moves upward. During the movement of the cleaning plate 81, the two guide blocks 82 and the two guide rods 83 limit the movement of the cleaning plate 81. During the movement of the cleaning plate 81, the bristles 84 thereon can brush the dustproof partition 23 and brush off the dust attached to the dustproof partition 23, so that the dust is attached to the bristles 84. This design can clean the dust attached to the dustproof partition 23, avoid the dust from clogging the dustproof partition 23, and ensure the air pollution monitoring device 21 for the monitoring effect of the atmosphere;

[0092] When the cleaning plate 81 moves to the upper limit position, the bristles 84 on the cleaning plate 81 will pass through the comb teeth 9. At this time, the comb teeth 9 can scrape off the dust attached to the bristles 84, that is, the dust will be transferred from the bristles 84 to the comb teeth 9. In addition, when the cleaning plate 81 moves upward, it can also drive the lifting block 103 to move upward through the connecting plate 104. When the lifting block 103 moves upward, it can stretch the sealing bag 105. When the sealing bag 105 is stretched, the sealing bag 105 can perform air extraction through the dust removal pipe 106. When the photovoltaic power generation panel 34 is reversed and reset, the photovoltaic power generation panel 34 no longer applies tension to the cleaning plate 81 through the pull rope 85. 81 will also move down and reset under the action of gravity, and the lifting block 103 will also reset accordingly. The lifting block 103 will squeeze the sealing bag 105 during the resetting process. When the sealing bag 105 is squeezed, the gas in the sealing bag 105 will be pressed into the dust removal pipe 106 and sprayed out through the dust removal pipe 106. The mouth of the dust removal pipe 106 is set toward the comb teeth 9. When the gas is sprayed through the dust removal pipe 106, the gas can blow away the dust attached to the comb teeth 9, thereby cleaning the dust on the comb teeth 9. This design can ensure the cleanliness of the bristles 84, and then ensure the cleaning effect of the bristles 84 on the dust-proof partition 23.
