Description

Technical Field

[0001] This invention belongs to the field of environmental monitoring technology, and specifically relates to an ecological environment monitoring device. Background Technology

[0002] The ecological environment is a complex ecosystem that relates to the sustainable development of society and the economy. It encompasses the quantity and quality of water resources, land resources, biological resources, and climate resources that affect human survival and development. In ecological environment monitoring, air quality monitoring is a crucial component. It typically requires the use of environmental monitoring equipment to monitor the concentration of gases in the atmosphere in real time. The accuracy and stability of this monitoring data directly affect the scientific validity of environmental governance decisions.

[0003] Existing air quality monitoring is usually achieved through environmental monitoring equipment. Currently, most common environmental monitoring equipment used for air monitoring includes a vertically set column with a base welded to the bottom and a monitor and an air intake pipe connected to the monitor fixedly installed at the top. The air intake pipe is exposed to the outdoor natural environment, and the air enters the monitor through the air intake pipe for monitoring.

[0004] However, during monitoring, outdoor environments are prone to wind. When the natural wind suddenly increases, a large amount of turbulent airflow rushes into the monitor in the form of eddies and deflections, causing the gas concentration detected by the monitor to be instantly "diluted." This makes the monitored values ​​easily deviate significantly from the true values, making it difficult to guarantee the accuracy and stability of the data. To solve this problem, most systems currently install filters inside the air intake pipe. This not only reduces the wind speed as it passes through the filter but also filters large particles in the atmosphere. However, filters are essentially planar porous structures. Although they can slightly reduce wind speed and trap large particles, they do not easily change the direction of airflow. Turbulent airflow continues to rush into the monitor in the form of eddies and deflections, and the accuracy and stability of the monitoring data still cannot be effectively guaranteed. Therefore, overcoming the above-mentioned technical problems and defects has become a key issue that needs to be addressed. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art, where outdoor environments are prone to wind, and when the natural wind suddenly increases, a large amount of turbulent airflow rushes into the monitoring instrument in the form of eddies and deflections, causing the gas concentration detected by the monitoring instrument to be instantly "diluted", and the monitored value is prone to deviate significantly from the true value, making it difficult to guarantee the accuracy and stability of the data. Thus, an ecological environment monitoring device is realized.

[0006] To achieve the above-mentioned objectives, the technical solution of this invention is as follows: an ecological environment monitoring device, comprising a base, a support frame, and a monitoring instrument body. The support frame is fixedly installed on the upper end of the base, and the monitoring instrument body for gas monitoring is fixedly installed on the support frame. An air inlet pipe is fixedly connected to one side of the monitoring instrument body. A cavity is fixedly connected to the end of the air inlet pipe away from the monitoring instrument body. Ears are symmetrically fixedly connected to both sides of the cavity at the end away from the air inlet pipe. A T-shaped shaft is slidably connected to each ear through a through hole. A honeycomb plate is fixedly connected to two T-shaped shafts for attenuating and rectifying the airflow. Two foam boards for attenuating the airflow are installed inside the cavity near the air inlet pipe. A suction hood is fixedly connected to the end of the cavity away from the air inlet pipe. Several mounting shafts are rotatably mounted on the suction hood at even intervals. A downwardly inclined rotating plate is fixedly mounted on each mounting shaft inside the suction hood. A connecting rod is fixedly mounted to one end of each mounting shaft outside the suction hood. The end of each connecting rod away from the mounting shaft is rotatably connected to a linkage rod.

[0007] In the aforementioned ecological environment monitoring equipment, the diameter of the middle part of the air inlet pipe is smaller than the diameters at both ends.

[0008] In the aforementioned ecological environment monitoring device, each T-shaped shaft is fitted with a number of elastic balls and spacers at intervals, and the elastic balls and spacers are located between the T-shaped end of the T-shaped shaft and the lug.

[0009] In the aforementioned ecological environment monitoring device, slide rail assemblies are symmetrically fixedly installed on both sides of the cavity. Each slide rail assembly includes a U-shaped frame, a sliding block, and ball bearings. The U-shaped frame is fixedly installed on the inner wall of the cavity. Several ball bearings are rotatably installed on both sides of the U-shaped frame. A sliding block adapted to the ball bearings is slidably connected to the middle of the U-shaped frame. The sliding block is fixedly connected to the honeycomb panel.

[0010] In the aforementioned ecological environment monitoring device, the two foam panels are high-density polyurethane foam and low-density polyurethane foam, respectively, used to attenuate the airflow, and the low-density polyurethane foam is located at one end near the air inlet pipe.

[0011] In the aforementioned ecological environment monitoring equipment, a flow equalization plate is fixedly installed inside the cavity, and the flow equalization plate is located between two foam boards.

[0012] In the aforementioned ecological environment monitoring equipment, the diameter of the cavity is larger than the diameter of the air inlet pipe and the air outlet of the suction hood.

[0013] In the above-mentioned ecological environment monitoring equipment, a number of first magnets are fixedly installed at even intervals on the upper front of each rotating plate, and a number of second magnets are fixedly installed at even intervals on the lower back of each rotating plate, and the first magnets and second magnets between two adjacent rotating plates repel each other.

[0014] In the aforementioned ecological environment monitoring equipment, several arc-shaped plates are fixedly installed at intervals on the front side of each rotating plate.

[0015] In the aforementioned ecological environment monitoring equipment, a cam is fixedly installed on the mounting shaft located outside one side of the suction hood, and several sets of baffles, each set consisting of two, are fixedly installed on the outer wall of the suction hood to limit the movement of the cam.

[0016] Compared with the prior art, the ecological environment monitoring device of the present invention has the following beneficial effects: 1. An ecological environment monitoring device of the present invention, through the arrangement of a suction hood, a mounting shaft, and a rotating plate, when the natural wind suddenly increases, the wind blows towards the rotating plate, causing it to rotate automatically around the mounting shaft. The opening and closing degree between adjacent rotating plates decreases accordingly, which not only changes the flow direction of the airflow but also effectively reduces the air intake volume and blocks large particles. Through the ingenious cooperation of the connecting rod and the linkage rod, each rotating plate can rotate synchronously and maintain a consistent opening and closing degree, so that the large amount of turbulent eddies and deflections that surge in are dispersed into laminar flow, effectively eliminating the interference of eddies and deflections on the monitoring data, and further improving the accuracy and stability of the monitoring data.

[0017] 2. The ecological environment monitoring device of the present invention, through the arrangement of the cavity and honeycomb plate, can not only change the flow direction of the airflow and rectify the airflow, transforming it into a uniform small laminar flow and eliminating eddies and deviations, but also attenuate the airflow. Furthermore, the cooperative design of the two foam plates can further attenuate turbulence, effectively preventing a large amount of chaotic eddies and deviations from rapidly entering the monitoring instrument body and affecting the accuracy of monitoring. Moreover, through the cooperative design of the lugs and T-shaped shaft, when the external wind suddenly picks up, a large amount of airflow is blown towards the honeycomb plate, causing it to move along the T-shaped shaft. The distance between the honeycomb plate and the foam plate decreases accordingly. The rectified airflow is attenuated by the adjacent foam plate before it has a chance to diffuse again, effectively preventing residual pulsating airflow from affecting the attenuation effect due to secondary development of disturbances. Through the cooperative design of the elastic ball and the spacer ring, when the wind speed decreases, the honeycomb plate automatically resets under the action of the elastic ball, and the distance returns to normal, thereby effectively ensuring the air intake throughput and ensuring that the monitoring instrument body can perform monitoring normally.

Detailed Implementation

[0020] The following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed description of an ecological environment monitoring device according to the present invention.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Example 1: This embodiment discloses an ecological environment monitoring device. Through the arrangement of the cavity 5 and the honeycomb plate 15, the airflow direction can be changed, the airflow rectified, and the airflow converted into a uniform laminar flow, eliminating eddies and deviations. Furthermore, the airflow can be attenuated. The combined design of the two foam plates 16 further attenuates turbulence, effectively preventing a large amount of chaotic eddies and deviations from rapidly entering the monitoring instrument body 3 and affecting the accuracy of monitoring. Moreover, through the combined design of the lugs 13 and the T-shaped shaft 14, when a sudden wind blows, a large amount of airflow is directed towards the honeycomb plate 15, causing it to move along the T-shaped shaft 14. The distance between the honeycomb plate 15 and the foam plates 16 decreases accordingly. The rectified airflow is attenuated by the adjacent foam plates 16 before it has a chance to diffuse again, effectively preventing residual pulsating airflow from affecting the attenuation effect due to secondary disturbances. (Refer to...) Figures 1-14It mainly includes a base 1, a support frame 2, and a monitoring instrument body 3. The support frame 2 is fixedly installed on the upper end of the base 1, and the monitoring instrument body 3, which can monitor gases, is fixedly installed on the support frame 2. (The monitoring instrument body 3 is an instrument for monitoring gas concentration (such as sulfur dioxide in the gas). Since it is an existing instrument, it will not be described in detail.) An air inlet pipe 4 is fixedly connected to one side of the monitoring instrument body 3. The end of the air inlet pipe 4 away from the monitoring instrument body 3 is fixedly connected to a cavity 5. The two sides of the cavity 5 away from the air inlet pipe 4 are symmetrically fixedly connected to ear seats 13. Each ear seat 13 is slidably connected to a T-shaped shaft through a through hole. 14. Two T-shaped shafts 14 are fixedly connected to honeycomb panels 15 for attenuating and rectifying airflow. Two foam panels 16 for attenuating airflow are installed inside the cavity 5 near the air inlet pipe 4. The cavity 5 away from the air inlet pipe 4 is fixedly connected to a suction hood 6. The suction hood 6 is rotatably mounted with several mounting shafts 7 at even intervals. Each mounting shaft 7 inside the suction hood 6 is fixedly mounted with a downwardly inclined rotating plate 701. Each mounting shaft 7 outside the suction hood 6 is fixedly mounted with a connecting rod 9 at one end. The end of each connecting rod 9 away from the mounting shaft 7 is rotatably connected to a linkage rod 10. With the arrangement of the suction hood 6, mounting shaft 7, and rotating plate 701, when the natural wind suddenly increases, the wind blows towards the rotating plate 701, causing it to rotate automatically around the mounting shaft 7. The opening and closing degree between adjacent rotating plates 701 decreases accordingly, which not only changes the airflow direction but also effectively reduces the intake air volume and blocks large particles. Through the ingenious cooperation of the connecting rod 9 and the linkage rod 10, each rotating plate 701 can rotate synchronously and maintain a consistent opening and closing degree, so that the large amount of turbulent eddies and deflections that surge in are dispersed into laminar flow, effectively eliminating the interference of eddies and deflections on the monitoring data and further improving the accuracy and stability of the monitoring data.

[0023] In this embodiment, refer to Figure 1 , Figure 6 , Figure 7 and Figure 13 The diameter of the middle part of the air intake pipe 4 is smaller than that of the two ends. Similar to the principle of the Venturi tube, the airflow speed increases in the middle part of the air intake pipe 4. According to Bernoulli's principle, the static pressure will decrease significantly, forming a local negative pressure zone in the middle part of the air intake pipe 4. The negative pressure in the middle part of the air intake pipe 4 can actively "draw in" gas from a distance. This is equivalent to obtaining additional suction force without adding a high-power air pump, which facilitates the entry of natural wind into the monitoring instrument body 3.

[0024] In this embodiment, refer to Figure 7 and Figure 8Each of the T-shaped shafts 14 is provided with a plurality of elastic balls 1401 and spacers 1402 at intervals, and the elastic balls 1401 and spacers 1402 are located between the T-shaped end of the T-shaped shaft 14 and the ear seat 13. In practical use, when the outside wind speed decreases, the T-shaped rod is reset due to the elasticity of the elastic ball 1401, which in turn drives the honeycomb plate 15 to reset, thereby effectively ensuring the air intake flow and ensuring that the monitoring instrument body 3 can perform normal monitoring.

[0025] In this embodiment, refer to Figure 7 and Figure 8 The cavity 5 has slide rail assemblies 18 symmetrically fixedly installed on both sides. Each slide rail assembly 18 includes a U-shaped frame 1801, a sliding block 1802, and a ball bearing 1803. The U-shaped frame 1801 is fixedly installed on the inner wall of the cavity 5. Several balls bearing 1803 are rotatably installed on both sides of the U-shaped frame 1801. A sliding block 1802 adapted to the balls bearing 1803 is slidably connected to the middle of the U-shaped frame 1801. The sliding block 1802 is fixedly connected to the honeycomb panel 15. Through the cooperative design of the U-shaped frame 1801, the balls bearing 1803, and the sliding block 1802, a low-friction, high-stability axial movement track can be provided for the honeycomb panel 15, ensuring that the honeycomb panel 15 can move quickly and smoothly in a predetermined direction under wind pressure.

[0026] In this embodiment, refer to Figure 7 The two foam panels 16 are high-density polyurethane foam and low-density polyurethane foam, respectively, used to attenuate the airflow, and the low-density polyurethane foam is located at one end near the air inlet pipe 4. In practical applications, high-density polyurethane foam is characterized by small pores, dense structure, high resistance, and strong interception ability. When airflow passes through it, the wind speed is significantly reduced. Moreover, after passing through high-density polyurethane foam, the originally turbulent airflow has been "violently" sorted into relatively orderly small airflows, and large-scale eddies are basically eliminated. Low-density polyurethane foam is characterized by large pores, loose structure, low resistance, and good air permeability. After being forcefully broken by high-density polyurethane foam, the airflow is basically orderly, but some small-scale pulsations and inhomogeneities still exist. The large pores of low-density polyurethane foam do not cause excessive resistance to airflow. Instead, it acts like a "flexible filter," gently smoothing out residual small-scale pulsations, making the airflow smoother and more uniform. Moreover, the low-density polyurethane foam has low resistance and does not cause excessive pressure drop, ensuring that the monitoring instrument body 3 still has sufficient air intake. At the same time, it can attenuate the wind speed one last time, thus effectively preventing a large amount of turbulent airflow from rushing into the monitoring instrument body 3 and causing inaccurate monitoring values. This significantly improves the accuracy and stability of gas monitoring data.

[0027] Example 2: Based on Embodiment 1, this embodiment discloses an ecological environment monitoring device, referring to... Figure 7 A flow equalization plate 17 is fixedly installed inside the cavity 5, and the flow equalization plate 17 is located between two foam boards 16. By setting the flow equalization plate 17, the uneven airflow can be reorganized into a uniform airflow with the same velocity on the cross-section. When this uniform airflow enters the low-density polyurethane foam board, each area of ​​the low-density polyurethane foam board bears the same intensity of airflow load. Its fine attenuation ability is fully and uniformly utilized, avoiding the situation of local overload while other areas are idle.

[0028] Example 3: The similarities to the above embodiments will not be repeated here, the differences being: This embodiment discloses an ecological environment monitoring device, referring to... Figure 1 , Figure 2 and Figure 7 The diameter of the cavity 5 is larger than that of the air inlet pipe 4 and the air outlet of the suction hood 6. After the airflow enters the cavity 5, the flow area suddenly increases and the flow velocity decreases significantly. This not only weakens the lateral inertia of the vortex or deflection flow and changes the flow direction of the airflow, but also attenuates the airflow, thereby effectively preventing a large number of turbulent vortices and deflections from rushing into the monitoring instrument body 3 and affecting the accuracy of the monitoring.

[0029] Example 4: The similarities to the above embodiments will not be repeated here, the differences being: This embodiment discloses an ecological environment monitoring device, referring to... Figure 9 and Figure 10 Each rotating plate 701 has several first magnets 702 evenly spaced and fixedly installed on its upper front side, and several second magnets 703 evenly spaced and fixedly installed on its lower back side. The first magnets 702 and second magnets 703 between two adjacent rotating plates 701 repel each other. When the natural wind decreases, driven by the repulsive force between the first magnets 702 and the second magnets 703, the rotating plate 701 resets, allowing the adjacent rotating plates 701 to reopen, and the natural wind can enter the monitoring instrument body 3 normally, ensuring normal monitoring. At the same time, compared with the traditional method of using torsion springs for reset, the passive automatic reset achieved by using magnetic repulsion effectively avoids the problem of torsion springs breaking due to long-term fatigue, and significantly improves the service life of the equipment.

[0030] Example 5: The similarities to the above embodiments will not be repeated here, the differences being: This embodiment discloses an ecological environment monitoring device, referring to... Figure 9 and Figure 10 Each of the rotating plates 701 has several arc-shaped plates 704 fixedly installed at intervals on its front side. Through the ingenious design of the arc-shaped plates 704, the natural wind can be "caught" and thus the natural wind can be better used to blow the rotating plates 701. This allows for timely control of the opening and closing degree of adjacent rotating plates 701, effectively avoiding the situation where the opening and closing degree of adjacent rotating plates 701 cannot be controlled in time when the natural wind suddenly increases.

[0031] Example 6: The similarities to the above embodiments will not be repeated here, the differences being: This embodiment discloses an ecological environment monitoring device, referring to... Figure 4 and Figure 5 A cam 12 is fixedly installed on the mounting shaft 7 located on the outside of one side of the suction hood 6. Several sets of baffles 11 are fixedly installed on the outer wall of the suction hood 6, with two in each set, for limiting the cam 12. The baffles 11 located on the upper part of the cam 12 can limit the cam 12, thereby preventing the rotating plate 701 from rotating too much upward and causing the rotating plate 701 to flip over. The baffles 11 located on the lower part of the cam 12 can limit the cam 12, thereby effectively preventing the cam 12 from rotating too much downward and causing the adjacent rotating plates 701 to completely close, thus effectively ensuring that the gas can enter the monitor body 3 normally.

[0032] Example 7: This embodiment discloses an ecological environment monitoring device, referring to... Figure 1 , Figure 4 , Figure 6 , Figure 7 , Figure 9 , Figure 11 , Figure 12 and Figure 13The filter 601 is designed to reduce wind speed immediately upon passing through it. The cleaning mechanism 8 cleans the filter 601 repeatedly, effectively preventing large particles from clogging it and affecting the monitoring of the instrument body 3. The system mainly includes a filter 601 fixedly installed at the end of the suction hood 6 away from the cavity 5; a cleaning mechanism 8 installed on the support frame 2 to clean the filter 601; the cleaning mechanism 8 includes a housing 801 fixedly connected to the support frame 2 and a mounting frame 802 fixedly installed on the suction hood 6; a straight toothed plate 804 slidably connected to the middle of the mounting frame 802; a cleaning brush 805 fixedly connected to the straight toothed plate 804; and a fan-shaped... A gear 803 is mounted on a mounting bracket 802. A linkage shaft 806 is rotatably mounted on the linkage shaft 806, which is fixedly mounted with a drive gear 807 that can mesh with the sector gear 803. A driven gear 815 that can mesh with a spur gear plate 804 is fixedly mounted on the linkage shaft 806. A first connecting rod 808 is rotatably mounted on the sector gear 803. A second connecting rod 809 is rotatably mounted on the end of the first connecting rod 808 away from the sector gear 803. A drive shaft 810 is rotatably mounted on the second connecting rod 809. The drive shaft 810 is rotatably mounted on a drive frame 811. The drive frame 811 is fixedly mounted on a housing 801. A drive motor 814 is fixedly mounted on the drive frame 811. A worm gear 813 is fixedly connected to the output shaft of the drive motor 814. A worm wheel 812 that meshes with the worm gear 813 is fixedly mounted on the drive shaft 810. In practical use, the drive motor 814 is started, which drives the worm 813 to rotate. The worm 813 meshes with the worm wheel 812, causing the worm wheel 812 to rotate. The worm wheel 812 drives the drive shaft 810 to rotate. With the cooperation of the first link 808 and the second link 809, the sector gear 803 reciprocates. The sector gear 803 meshes with the drive gear 807, causing the drive gear 807 to reciprocate. The drive gear 807 drives the linkage shaft 806 to reciprocate. The linkage shaft 806 drives the driven gear 815 to reciprocate. The driven gear 815 meshes with the spur gear plate 804, causing the spur gear plate 804 to move back and forth. This causes the cleaning brush 805 to reciprocate and clean the filter screen 601.

[0033] The working principle of an ecological environment monitoring device of the present invention is as follows: When it is necessary to monitor the ecological environment, the device is installed in a suitable location. The gas in the ecological environment can be monitored through the monitoring instrument body 3. During the monitoring process of the monitoring instrument body 3, when the natural wind suddenly increases, the natural wind blows towards the rotating plate 701, and the rotating plate 701 rotates, which reduces the opening and closing degree between adjacent rotating plates 701, reducing the amount of natural wind entering the cavity 5. The natural wind entering the cavity 5 blows towards the honeycomb plate 15, and the honeycomb plate 15 moves closer to the foam plate 16, which reduces the distance between the honeycomb plate 15 and the foam plate 16. After being rectified by the honeycomb plate 15, the airflow is attenuated by the foam plate 16 in a timely manner. After passing through the flow equalization plate 17 and the other foam plate 16, the airflow can be further attenuated again, thus effectively preventing a large amount of airflow from rushing into the monitoring instrument body 3 and affecting the monitoring accuracy of the monitoring instrument body 3. The attenuated airflow enters the monitoring instrument body 3 through the air inlet pipe 4, and the gas is monitored by the monitoring instrument body 3.

[0034] Bernoulli's principle, proposed by Swiss fluid physicist Daniel Bernoulli in 1726, is essentially the law of conservation of mechanical energy of fluids. It states that when an ideal fluid (incompressible and inviscid) is in steady flow, the sum of kinetic energy, gravitational potential energy, and pressure potential energy per unit volume of fluid remains constant along the same streamline.
