Description

Technical Field

[0001] The present invention belongs to the technical field of meteorological measurement, and specifically refers to a ventilation structure for a temperature sensor used in meteorological measurement. Background Art

[0002] Meteorological measurement equipment measures data such as temperature, humidity, wind speed, and air pressure in the air through components such as data chips and temperature sensors installed inside, to accurately judge and predict the recent weather changes. The meteorological observation system composed of various means can observe the atmospheric state and its changes from the ground to the high altitude, from the local area to the global area.

[0003] Currently, the existing ventilation structures for temperature sensors used in meteorological measurement have the following problems:

[0004] The existing ventilation structures for temperature sensors used in meteorological measurement do not have the ability to introduce external natural wind to the location of the meteorological sensor for cooling according to different wind directions, and the traditional ventilation structures for temperature sensors used in meteorological measurement also do not have the ability to still meet the cooling requirements of the meteorological temperature sensor when the external natural wind is small. Therefore, they cannot meet the current usage requirements for the ventilation structures of temperature sensors used in meteorological measurement. Summary of the Invention

[0005] In view of the above situation, to overcome the defects of the prior art, the present solution provides a ventilation structure for a temperature sensor used in meteorological measurement that can introduce external natural wind to the location of the meteorological sensor for cooling according to different wind directions, and can still meet the cooling requirements of the meteorological temperature sensor when the external natural wind is small.

[0006] A ventilation structure for a temperature sensor used in meteorological measurement proposed by the present solution includes a ventilation box, an air guiding cylinder, a one-way exhaust valve, a multi-faceted windward mechanism, and a reduced-flow guiding mechanism. The air guiding cylinder is communicatively connected to the upper wall of the ventilation box, and multiple groups of the one-way exhaust valves are communicatively connected to the side wall of the ventilation box. The multi-faceted windward mechanism includes a wind guiding mechanism, a wind filtering mechanism, and a wind lifting mechanism. The wind guiding mechanism penetrates through the inner wall of the air guiding cylinder, the wind filtering mechanism is arranged on the side of the wind guiding mechanism close to the air guiding cylinder, and the wind lifting mechanism penetrates through the inner wall of the air guiding cylinder below the wind guiding mechanism. The reduced-flow guiding mechanism includes a blocking mechanism and a liquid cooling mechanism. The blocking mechanism is arranged inside the wind filtering mechanism, and the liquid cooling mechanism is arranged on the side wall of the air guiding cylinder.

[0007] As a further optimization of the solution in this case, the air guiding mechanism includes an air guiding cylinder, a diffusing net cylinder, a lightweight air guiding ball and an air guiding spring. Multiple groups of the air guiding cylinders are arranged through the inner wall of the air suction cylinder at the end far from the ventilation box. The air guiding cylinder is a through cavity. The diffusing net cylinder is communicated with the side wall of the air guiding cylinder inside the air suction cylinder. The air guiding spring is arranged on the inner wall of the diffusing net cylinder at the end far from the air guiding cylinder. The lightweight air guiding ball is arranged on the side of the air guiding spring close to the air guiding cylinder. The inner diameter of the end of the air guiding cylinder far from the diffusing net cylinder is smaller than the outer diameter of the lightweight air guiding ball, and the lightweight air guiding ball blocks the end of the air guiding cylinder far from the diffusing net cylinder. The air filtering mechanism includes an annular slider, a moisture absorption cylinder, an inverted cone cylinder, a water absorption cotton layer, an air inlet groove and an air inlet cylinder. The annular slider is arranged between adjacent diffusing net cylinders. The air inlet cylinder is slidably arranged on the inner wall of the annular slider. The air inlet cylinder is a through cavity. The moisture absorption cylinder is arranged on the inner wall of the air inlet cylinder, and the moisture absorption cylinder is provided with an open upper end. The inverted cone cylinder is arranged through the bottom wall of the moisture absorption cylinder, and the inverted cone cylinder is a through setting. The water absorption cotton layer is arranged between the inverted cone cylinder and the moisture absorption cylinder. The air inlet groove is arranged at the end of the air inlet cylinder close to the top wall of the air suction cylinder, and the air inlet groove is a through setting. The air lifting mechanism includes a lifting bladder cylinder, a telescopic tube, a lightweight wind measuring ball, a wind measuring spring, an annular bladder pressing plate, an annular air bag and a one-way air outlet valve. Multiple groups of the lifting bladder cylinders are arranged through the inner wall of the air suction cylinder at the end close to the ventilation box. The lifting bladder cylinder is provided with an open end. The annular bladder pressing plate is arranged on the bottom wall of the moisture absorption cylinder, and the annular bladder pressing plate is slidably connected with the inner wall of the air suction cylinder. The annular air bag is arranged between the annular bladder pressing plate and the bottom wall of the air suction cylinder. The telescopic tube is arranged through the annular bladder pressing plate and communicated between the lifting bladder cylinder and the annular air bag. The wind measuring spring is arranged on the inner wall of one end of the lifting bladder cylinder. The lightweight wind measuring ball is arranged on the side of the wind measuring spring far from the inner wall of the lifting bladder cylinder. The inner diameter of the opening of the lifting bladder cylinder is smaller than the outer diameter of the lightweight wind measuring ball. Multiple groups of the one-way air outlet valves are arranged through the annular bladder pressing plate and communicated with the upper wall of the annular air bag. The inner diameter of the one-way air outlet valve is one-third of the inner diameter of the lifting bladder cylinder.

[0008] During use, the surfaces of the air suction cylinders are all windward surfaces. When the wind blows towards the surfaces of the air suction cylinders, the airflow uses the elasticity of the air guiding spring to push the lightweight air guiding ball away from the opening of the air guiding cylinder. The natural wind passes through the air guiding cylinder and flows into the air suction cylinder through the diffusing net cylinder. The airflow gathered inside the air suction cylinder flows into the air inlet cylinder through the air inlet groove. The airflow inside the air inlet cylinder flows into the water absorption cotton layer inside the moisture absorption cylinder. The water absorption cotton layer adsorbs the moisture in the airflow. The airflow after adsorption enters the ventilation box and cools the temperature sensor placed inside it. The heat-exchanged air is discharged through the one-way exhaust valve. Since the ventilation box is cylindrical, the airflow is blocked by the ventilation box and flows backward along both sides of it. When one side wall of the ventilation box is impacted by the wind, the one-way exhaust valves arranged on the other three sides quickly discharge the heat-exchanged air inside it under the action of the downwind airflow.

[0009] Preferably, the plugging mechanism includes a plugging spring, a groove, a heat insulation plate, a spring seat and a conduction groove. A plurality of the spring seats are arranged on the inner wall of the top of the moisture absorption cylinder, and a plurality of the grooves are arranged on the bottom wall of the moisture absorption cylinder on the outer side of the inverted cone cylinder. The grooves are open at the upper end. The conduction groove is arranged on the inner wall of the moisture absorption cylinder below the groove and is arranged in a penetrating manner. The groove is communicated with the conduction groove. The liquid cooling mechanism includes a liquid cooling copper pipe, a liquid cooling cylinder and a cooling copper plate. A plurality of the liquid cooling cylinders are arranged on the side wall of the ventilation box. The liquid cooling copper pipe penetrates through the ventilation box and is communicated with the air guiding cylinder and is arranged between the liquid cooling cylinder and the conduction groove. The cooling copper plate is arranged through the inner wall of one end of the liquid cooling cylinder close to the ventilation box.

[0010] During use, when the external wind force is small, the airflow drives the lightweight wind measuring ball and then enters the annular airbag with less flow. The air inside the annular airbag gradually discharges under the gravity of the air inlet cylinder. The air inlet cylinder slides along the inner wall of the annular slider and drives the moisture absorption cylinder to descend. The liquid cooling copper pipe uses the deformation of the plugging spring to push the heat insulation plate out of the groove. One end of the liquid cooling copper pipe away from the liquid cooling cylinder enters the moisture absorption cylinder. Since the water vapor adsorbed by the water absorption cotton layer inside the moisture absorption cylinder is cooled by the external air for a long time, the temperature inside the water absorption cotton layer is relatively low. The water absorption cotton layer cools the liquid cooling copper pipe. One end of the liquid cooling copper pipe away from the water absorption cotton layer extends into the liquid cooling cylinder. The liquid cooling copper pipe cools the liquid pre-placed inside the liquid cooling cylinder. Moreover, the water droplets falling to the bottom of the moisture absorption cylinder inside the water absorption cotton layer flow into the liquid cooling cylinder through the liquid cooling copper pipe. The liquid inside the liquid cooling cylinder is cooled and then cools the temperature sensor inside the ventilation box through the cooling copper plate.

[0011] Specifically, a positioning and installation mechanism is arranged on the bottom wall of the ventilation box. The positioning and installation mechanism includes an installation frame and an installation plate. The installation frame is arranged on the bottom wall of the ventilation box, and the installation plate is arranged on the side of the installation frame away from the ventilation box.

[0012] The beneficial effects obtained by the present solution with the above structure are as follows:

[0013] Compared with the prior art, the present solution combines a multi-faceted air guiding structure and a diversion liquid cooling structure. Through the arranged multi-faceted windward mechanism and the reduction-type diversion mechanism, under the combined use of the air guiding mechanism, the air filtering mechanism, the air lifting mechanism, the plugging mechanism and the liquid cooling mechanism, the airflow can be introduced into the ventilation box according to the flowing direction of the wind direction to ventilate and cool the sensor. Moreover, when the external natural wind is small and cannot meet the heat dissipation requirements of the temperature sensor, the evaporation cooling effect formed after the water absorption cotton layer adsorbs water vapor can be used to cool the liquid cooling copper pipe. The water vapor adsorbed inside the water absorption cotton layer is cooled by the external natural wind for a long time and has a relatively low temperature, so as to ensure the stable operation of the sensor under the state of less external ventilation volume.

The cooling copper plate 28 is arranged through the inner wall of one end of the liquid cooling cylinder 27 close to the ventilation box 1.

[0033] A positioning and installation mechanism 29 is arranged on the bottom wall of the ventilation box 1. The positioning and installation mechanism 29 includes an installation frame 30 and an installation plate 31. The installation frame 30 is arranged on the bottom wall of the ventilation box 1, and the installation plate 31 is arranged on the side of the installation frame 30 away from the ventilation box 1.

[0034] During specific use, when using the meteorological temperature sensor, the meteorological temperature sensor is placed inside the ventilation box 1. The monitoring end of the meteorological temperature sensor penetrates and is placed on the side wall of the ventilation box 1. The temperature measuring column is fixedly connected with the installation plate 31, the temperature measuring column is fixed in the temperature measuring area, the meteorological temperature sensor is erected in the air, the meteorological temperature sensor is turned on, and the remote terminal is electrically connected with the meteorological temperature sensor.

[0035] Example 1. There are many types of wind directions inside the temperature measurement area. The surfaces of the air guiding cylinders 2 are all set as windward surfaces. When the wind blows from a certain direction towards the surfaces of the air guiding cylinders 2, the airflows respectively push the lightweight air guiding balls 8 and the lightweight wind measurement balls 18 by the elasticity of the air guiding springs 9 and the wind measurement springs 19. The lightweight air guiding balls 8 are away from the openings of the air guiding cylinders 6, and the lightweight wind measurement balls 18 are away from the openings of the air lifting cylinders 16. The air guiding cylinders 6 and the air lifting cylinders 16 are respectively communicated with the air guiding cylinders 2. A part of the natural wind blowing on the surfaces of the air guiding cylinders 2 flows into the interiors of the air guiding cylinders 2 through the air guiding cylinders 6 and the air dispersion net cylinders 7. The airflows gathered inside the air guiding cylinders 2 flow into the interior of the air inlet cylinder 36 through the air inlet grooves 35. Another part of the natural wind blowing on the surfaces of the air guiding cylinders 2 flows into the interior of the annular airbag 33 through the air lifting cylinders 16 and the telescopic pipes 17. After the airflows inside the annular airbag 33 increase, the annular airbag 33 bulges. The annular airbag 33 drives the air inlet cylinder 36 to rise along the inner wall of the air guiding cylinder 2 through the annular airbag pressing plate 32. The air inlet cylinder 36 drives the moisture absorption cylinder 12 to rise along the inner wall of the annular slider 11. The moisture absorption cylinder 12 drives the conduction groove 38 away from the liquid cooling copper pipe 26. The blocking spring 22 is normally set to be elongated. The blocking spring 22 drives the heat insulation plate 24 into the interior of the groove 23 by its own deformation to block the conduction groove 38. Since the inner diameter of the one-way air outlet valve 34 is smaller than the inner diameter of the air lifting cylinder 16, the air intake volume of the annular airbag 33 is greater than the air exhaust volume, and the annular airbag 33 can bear the air inlet cylinder 36;

[0036] The airflows inside the air inlet cylinder 36 flow into the water absorption cotton layer 14 inside the moisture absorption cylinder 12. The water absorption cotton layer 14 adsorbs the moisture in the airflows, reducing the influence probability of the external moisture on the meteorological temperature sensor. The airflows after being adsorbed by the water absorption cotton layer 14 enter the ventilation box 1 to perform ventilation and cooling operations on the temperature sensor placed inside it. The heat-exchanged air is discharged through the one-way exhaust valve 3. Since the ventilation box 1 is cylindrical, the airflows are blocked by the front surface of the ventilation box 1 and then flow backward along its two sides. When one side wall of the ventilation box 1 is impacted by the wind, the one-way exhaust valves 3 provided on the other three sides quickly discharge the heat-exchanged air inside it under the action of the downwind airflows, completing the air cooling operation on the meteorological temperature sensor;

[0037] Embodiment 2. This embodiment is based on the above embodiment. When the external wind force is small, the natural wind cannot meet the heat dissipation requirements of the meteorological temperature sensor, and the amount of air flowing into the annular airbag 33 after being pushed by the external air flow through the lightweight anemometer ball 18 is small. At this time, the air intake of the annular airbag 33 is less than the exhaust volume, and the air inside the annular airbag 33 gradually discharges under the gravity of the air inlet cylinder 36. The air inlet cylinder 36 slides along the inner wall of the annular slider 11 to drive the moisture absorption cylinder 12 to descend. The liquid cooling copper tube 26 uses the deformation of the plugging spring 22 to push the heat insulation plate 24 out of the groove 23. One end of the liquid cooling copper tube 26 away from the liquid cooling cylinder 27 enters the moisture absorption cylinder 12. Since the water vapor adsorbed by the water absorption cotton layer 14 inside the moisture absorption cylinder 12 is cooled by the external air for a long time, the temperature inside the water absorption cotton layer 14 is relatively low, and the water absorption cotton layer 14 can cool the liquid cooling copper tube 26. A heat insulation coating is applied to the side of the liquid cooling copper tube 26 in contact with the external air. Half of the water is pre-injected into the liquid cooling cylinder 27. One end of the liquid cooling copper tube 26 away from the water absorption cotton layer 14 extends into the water inside the liquid cooling cylinder 27. The liquid cooling copper tube 26 cools the water inside the liquid cooling cylinder 27, and a water inlet is provided at one end of the liquid cooling copper tube 26 close to the moisture absorption cylinder 12. The water droplets falling to the bottom of the moisture absorption cylinder 12 inside the water absorption cotton layer 14 flow into the liquid cooling cylinder 27 through the liquid cooling copper tube 26. The water inside the liquid cooling cylinder 27 is cooled and then cools the temperature sensor inside the ventilation box 1 through the cooling copper plate 28, completing the water cooling operation of the temperature sensor; repeat the above operation when using it next time.
