Description

Technical Field

[0001] This invention relates to the field of environmental monitoring technology, and in particular to a wind speed environmental measurement device. Background Technology

[0002] Wind speed detection is of great significance in many fields such as environmental meteorology, industrial equipment, mining safety, and healthcare. With the development of my country's wind power industry, the advancement of detection technology, and people's increasing environmental requirements, the demand for measurement accuracy and functionality of detection instruments is becoming increasingly higher. Wind speed sensors are sensors used to measure the speed of airflow. They can be used as airflow control sensors in air conditioning systems and air flow sensors in automobiles. In addition, they have attracted attention as an indispensable sensor in wind tunnel experiments in the fields of fluid mechanics and aerodynamics.

[0003] Chinese invention patent CN107831333A discloses a device for measuring wind speed. The base is bolted to a bracket and is a hollow shell. A rotating shaft is installed inside the base via two rolling bearings. The top of the rotating shaft passes through the upper surface of the base. The two rolling bearings are vertically installed on the inner sidewall of the base and separated by a spacer sleeve. The lower rolling bearing is axially fixed by the shoulder of the rotating shaft, and the upper rolling bearing is axially fixed by an end cap. The end cap is fixed to the base with four evenly arranged screws. The rotating frame is fixed to the rotating shaft with four evenly arranged screws. The rotating frame is generally disc-shaped, with the top surface of its middle part recessed inward. The top of the rotating shaft extends into this recess. Three evenly arranged cups are mounted on the rotating frame, and four evenly distributed magnets are mounted below the rotating shaft. Four sensors are mounted at the same height on the base. The device has a simple overall structure. The cup device installed on the rotating base is lightweight and operates sensitively, making the entire device lightweight and stable. It measures wind speed by calculating pulses, and the entire device has high measurement accuracy.

[0004] However, most existing wind speed sensors are fragile and easily damaged. Once damaged, they are difficult to replace, requiring the re-installation of speed measuring stakes, which is troublesome. Furthermore, wind speed measuring instruments do not have height and wind direction adjustment functions. Wind direction adjustment is not fixed due to seasonal weather changes, making manual adjustment inconvenient. The internal chip is generally powered by disposable batteries that are replaceable, lacking rechargeable and rechargeable functions. Frequent battery replacement is also troublesome, resulting in short battery life. To solve the above problems, there is an urgent need for a wind speed environmental measurement device. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention adopts the following technical solution: a wind speed environmental measurement device, comprising a directional control mechanism, a drive mechanism, a support mechanism, and a height adjustment mechanism; the support mechanism includes a base plate and an adjustment plate, four sets of sliding rods are fixedly installed on the base plate, the adjustment plate is slidably installed on the sliding rods, the height adjustment mechanism is set on the adjustment plate, a steering mechanism is set above the support column of the height adjustment mechanism, and the directional control mechanism and the drive mechanism are set on the steering mechanism; the directional control mechanism includes two sets of directional control components and directional control sliding columns, the directional control sliding columns are fixedly installed on the directional control mechanism, the directional control components are symmetrically rotated on both sides of the directional control sliding columns, the drive mechanism includes a protective net and fan blades, the protective net is fixedly installed on the steering mechanism, the fan blades are rotatably installed inside the protective net, the central axis of the protective net is coplanar with the axis of the directional control sliding column; a swing arm is rotatably installed on the support plate of the steering mechanism, a transmission mechanism is connected between the fan blades and the swing arm, a sensor is set on the arc plate of the support plate, and the sensor detects the swing speed of the swing arm.

[0006] Furthermore, the support mechanism also includes a top plate and limiting bolts. The top plate is fixedly installed on the top of four sets of sliding rods, and four sets of limiting rods are evenly fixed below the top plate. Each limiting rod has a graduation mark, and each set of limiting rods corresponds to a set of limiting bolts. The limiting bolts are rotatably mounted on the limiting rods. The adjusting disc has four sets of sliding holes, each set corresponding to a set of limiting rods, and the limiting rods and their corresponding sliding holes are coaxial. By rotating the limiting bolts, the position of the limiting bolts on the limiting rods is adjusted to determine the height of the wind speed to be measured.

[0007] Furthermore, the height adjustment mechanism includes a support column and an electric cylinder. The bottom of the support column is fixedly mounted on the adjustment plate, and the middle part of the support column is slidably mounted on the middle of the top plate. The electric cylinder is fixedly mounted inside the support column, and its output end is fixedly mounted to the bottom plate. When the output end of the electric cylinder extends, its reaction force drives the support column to move upward, adjusting the height of the drive mechanism until the limit rod slides into the sliding hole, and until the limit bolt contacts the adjustment plate, thus restricting the movement of the adjustment plate.

[0008] Furthermore, the steering mechanism includes a turntable and a support plate. The turntable is rotatably mounted on the top of the support column, and a bearing is connected between the turntable and the support column. The support plate is fixedly mounted above the turntable, and a right-angle plate is provided above the turntable, with the right-angle plate and the support plate being positioned opposite each other.

[0009] Furthermore, the directional control assembly includes a directional control plate and a directional control rod. The directional control plate is provided with a support pin and a connecting pin, and the directional control plate is perpendicular to the ground. The directional control plate is rotatably mounted on a right-angle plate via the support pin, and the connecting pin is fixedly mounted on the inner side of the directional control plate. Friction texture is provided on the outer side of the directional control plate, and the first end of the directional control rod is rotatably mounted on the connecting pin. The friction texture increases the contact area with the wind, making it easier to steer the drive mechanism in a direction opposite to the wind direction.

[0010] Furthermore, the direction control mechanism also includes a slider and a return spring. The slider is slidably mounted on the direction control slide column, which is equipped with a locking block. The return spring is slidably mounted on the direction control slide column, and the slider is positioned between the locking block and the return spring. The second end of the direction control plate is rotatably mounted on the slider. When the wind blows towards the direction control plate, under the action of the two sets of direction control plates, the two sets of direction control components drive the turntable to rotate via the right-angle plate until the turntable drives the drive mechanism to face the wind direction. At this point, the two sets of direction control components reach balance, and the turntable stops rotating.

[0011] Furthermore, the drive mechanism also includes a transmission disc and a generator. The transmission disc is rotatably mounted outside the protective netting and is fixedly mounted to the fan blades. An eccentric column is provided on the transmission disc. The generator is fixedly mounted on the motor frame of the protective netting, and a U-shaped frame rod connects the eccentric column and the input shaft of the generator. When the fan blades rotate, they drive the transmission disc to rotate, and the transmission disc drives the input shaft of the generator to rotate through the U-shaped frame rod, thus generating electricity.

[0012] Furthermore, a storage battery is installed inside the support column, and a wire connects the storage battery to the generator. The electric cylinder is electrically connected to the storage battery. The generator transmits the generated electrical energy to the storage battery via the wire, and the storage battery provides power to the electric cylinder.

[0013] Furthermore, the transmission mechanism includes a transmission rod and a connecting rod. The first end of the transmission rod is rotatably mounted on an eccentric column. A sliding groove and a pin are provided on the support plate. The connecting rod is slidably mounted on the sliding groove. The second end of the transmission rod is rotatably connected to the first end of the connecting rod. The middle part of the swing rod is rotatably mounted on the pin. A rocker arm is connected between the second end of the connecting rod and the first end of the swing rod. When the transmission disc rotates, the eccentric column drives the transmission rod to swing, the transmission rod drives the connecting rod to slide on the sliding groove, and the connecting rod drives the swing rod to swing on the pin via the rocker arm.

A transmission mechanism is connected between the fan blade 52 and the swing rod 7. A sensor 8 is installed on the arc plate 323 of the support plate 32. The sensor 8 detects the swing speed of the swing rod 7.

[0028] like Figure 1 , Figure 2 As shown, the support mechanism includes a base plate 11, sliding rods 12, a top plate 13, limiting rods 14, limiting bolts 15, and an adjusting plate 16. The base plate 11 has gripping feet 111 at its bottom to increase the friction between the base plate 11 and the ground surface, thus fixing the base plate 11 to the ground. There are four sets of sliding rods 12, evenly fixed to the base plate 11. The top plate 13 is fixed to the top of the sliding rods 12. Four sets of limiting rods 14 are evenly arranged below the top plate 13. There are four limiting bolts 15. The system consists of four sets of limit bolts 15 and limit rods 14. The limit bolts 15 are rotatably mounted on the limit rods 14, which are marked with scales. The adjustment disc 16 is slidably mounted on four sets of slide rods 12. The adjustment disc 16 has four sets of sliding holes 161, each corresponding to a limit rod 14. The limit rods 14 and their corresponding sliding holes 161 are coaxial. By rotating the limit bolts 15, the position of the limit bolts 15 on the limit rods 14 is adjusted to determine the height of the wind speed to be measured.

[0029] like Figure 2 , Figure 3 , Figure 4As shown, the height adjustment mechanism includes a support column 21, an electric cylinder 22, and a battery 23. The bottom of the support column 21 is fixedly mounted on the adjustment plate 16, and the middle part of the support column 21 is slidably mounted on the middle part of the top plate 13. The electric cylinder 22 is fixedly mounted inside the support column 21, and the output end of the electric cylinder 22 is fixedly mounted to the bottom plate 11. When the output end of the electric cylinder 22 extends, its reaction force drives the support column 21 to move upward, adjusting the height of the drive mechanism until the limit rod 14 slides into the sliding hole 161, and until the limit bolt 15 contacts the adjustment plate 16, limiting the movement of the adjustment plate 16. The battery 23 is fixedly mounted inside the support column 21 and is electrically connected to the electric cylinder 22, providing power to the electric cylinder 22.

[0030] like Figure 2 , Figure 3 , Figure 4 As shown, the steering mechanism includes a turntable 31, a support plate 32, a right-angle plate 33, and a bearing 34. The turntable 31 is rotatably mounted on the top of the support column 21, and the bearing 34 is connected between the turntable 31 and the support column 21. The support plate 32 and the right-angle plate 33 are fixedly mounted on the turntable 31, with the support plate 32 and the right-angle plate 33 facing each other. The support plate 32 is provided with a sliding groove 321, a pin 322, and an arc plate 323.

[0031] like Figure 2 , Figure 7 , Figure 8 , Figure 9As shown, the direction control mechanism includes a direction control assembly 41, a direction control slide column 42, a slider 43, and a return spring 44. There are two sets of direction control assemblies 41, symmetrically arranged on the right-angle plate 33. The direction control slide column 42 is fixedly installed on the right-angle plate 33, and the two sets of direction control assemblies 41 are symmetrically arranged on both sides of the slide column 42. The direction control assembly 41 includes a direction control plate 411 and a direction control rod 412. The direction control plate 411 is provided with a support pin 4111 and a connecting pin 4112, and is perpendicular to the ground. The direction control plate 411 is rotatably mounted on the right-angle plate 33 via the support pin 4111, controlling the direction... Plate 411 is perpendicular to the ground; connecting pin 4112 is fixedly installed on the inner side of the directional control plate 411, and friction texture is provided on the outer side of the directional control plate 411. The first end of the directional control rod 412 is rotatably installed on the connecting pin 4112. The friction texture increases the contact area with the wind, making it easier to turn the drive mechanism in the direction opposite to the wind direction; slider 43 is slidably installed on the directional control slide column 42. A locking block 421 is provided on the directional control slide column 42. The return spring 44 is slidably installed on the directional control slide column 42. The slider 43 is located between the locking block 421 and the return spring 44. The second end of the directional control plate 411 is rotatably installed on the slider 43. When the wind blows towards the direction control plate 411, under the action of the two sets of direction control plates 411, the two sets of direction control components 41 drive the turntable 31 to rotate through the right-angle plate 33. At the same time, the direction control plate 411 drives the slider 43 to slide on the direction control slide column 42 through the direction control rod 412. The return spring 44 is compressed, and the included angle between the two direction control plates 411 becomes smaller until the turntable 31 drives the drive mechanism to face the wind direction. The two sets of direction control components 41 reach balance, and the turntable 31 stops rotating. The wind speed is determined according to the included angle between the two sets of direction control plates 411.

[0032] like Figure 2 , Figure 5 As shown, the drive mechanism includes a protective net 51, fan blades 52, a transmission disc 53, a U-shaped frame rod 54, a generator 55, and a wire 56. The protective net 51 is fixedly installed on the steering mechanism, and the fan blades 52 are rotatably installed inside the protective net 51. The central axis of the protective net 51 is coplanar with the axis of the directional sliding column 42. When the wind blows towards the fan blades 52, the fan blades 52 rotate. The transmission disc 53 is rotatably installed outside the protective net 51. The transmission disc 53 is fixedly installed with the fan blades 52, and the fan blades 52 drive the transmission disc 53 to rotate. An eccentric column 531 is provided on the transmission disc 53. The generator 55 is fixedly installed on the motor frame 511 of the protective net 51. A U-shaped frame rod 54 is connected between the eccentric column 531 and the input shaft of the generator 55. The transmission disc 53 drives the input shaft of the generator 55 to rotate through the U-shaped frame rod 54, so that the generator 55 generates electricity. A wire 56 is connected between the battery 23 and the generator 55. The generator 55 transmits the generated electrical energy to the battery 23 for storage through the wire 56.

[0033] like Figure 2 , Figure 6 , Figure 9As shown, the transmission mechanism includes a transmission rod 61, a connecting rod 62, and a rocker arm 63. The first end of the transmission rod 61 is rotatably mounted on the eccentric column 531, the connecting rod 62 is slidably mounted on the slide groove 321, the second end of the transmission rod 61 is rotatably connected to the first end of the connecting rod 62, the middle part of the rocker arm 7 is rotatably mounted on the pin 322, and the rocker arm 63 is connected between the second end of the connecting rod 62 and the first end of the rocker arm 7. When the transmission disc 53 rotates, the eccentric column 531 drives the transmission rod 61 to swing, the transmission rod 61 drives the connecting rod 62 to slide on the slide groove 321, and the connecting rod 62 drives the rocker arm 7 to swing on the pin 322 through the rocker arm 63. The second end of the rocker arm 7 swings inside the arc plate 323, and the sensor 8 is fixedly mounted outside the arc plate 323. The sensor 8 detects the number of swings of the rocker arm 7. When the fan blade 52 is opposite to the wind direction, the number of swings of the rocker arm 7 tends to stabilize, the wind speed is detected, and the sensor 8 outputs a signal.

[0034] Working principle: When detecting wind speed, the gripper 111 is fixedly installed in the ground. According to the height to be measured, the position of the limit bolt 15 on the limit rod 14 is adjusted to determine the height of the wind speed to be measured. The electric cylinder 22 is started, and the output end of the electric cylinder 22 extends. Under its reaction force, it drives the support column 21 to move upward. The height of the drive mechanism is adjusted, and the limit rod 14 slides into the sliding hole 161 until the limit bolt 15 contacts the adjustment plate 16. The limit bolt 15 restricts the movement of the adjustment plate 16. At this time, the fan blade 52 is at the height of the wind speed to be measured.

[0035] When the wind blows onto the direction control plate 411, the two sets of direction control plates 411 cause the two sets of direction control components 41 to rotate the turntable 31 via the right-angle plate 33. At the same time, the direction control plate 411 drives the slider 43 to slide on the direction control slide column 42 via the direction control rod 412. The return spring 44 is compressed, and the angle between the two direction control plates 411 becomes smaller until the turntable 31 drives the drive mechanism to face the wind direction. The two sets of direction control components 41 reach balance, and the turntable 31 stops rotating. The wind speed can be initially judged based on the angle between the two sets of direction control plates 411.

[0036] During this process, the wind blows towards the fan blade 52, causing it to rotate. The fan blade 52 drives the transmission disk 53 to rotate, and the transmission disk 53 drives the input shaft of the generator 55 to rotate via the U-shaped frame rod 54, causing the generator 55 to generate electricity. The generator 55 then transmits the generated electrical energy to the storage battery 23 via the wire 56. When the transmission disk 53 rotates, the eccentric column 531 drives the transmission rod 61 to swing. The transmission rod 61 drives the connecting rod 62 to slide on the slide groove 321. The connecting rod 62 drives the swing rod 7 to swing on the pin 322 via the rocker arm 63. As the drive mechanism turns to face the wind direction, the sensor 8 detects that the swing speed of the swing rod 7 is constantly increasing until the drive mechanism faces the wind direction, the swing speed of the swing rod 7 reaches its maximum and tends to stabilize. The sensor 8 detects the wind speed based on the rotation speed of the swing rod 7 and outputs a signal.

[0037] After the test is completed, turn off the electric cylinder 22, restore the adjustment plate 16 to its initial position, pull the base plate 11 out of the ground, and the two sets of directional control components 41 return to their initial positions under the action of the reset spring 44.

[0038] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the protection scope of this invention.
