Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lifting structure technology, and in particular relates to a probe lifting structure for a hot-wire anemometer. Background Technology
[0002] Hot-wire anemometers play a crucial role in meteorological monitoring, industrial ventilation, and building environment monitoring due to their high precision and fast response. Their core working principle is to calculate wind speed by sensing the airflow heat dissipation rate through a hot-wire sensor. The height and position of the probe directly affect the accuracy and reliability of the measurement data. Therefore, the probe lifting structure, as the core component for adjusting the measurement position, is of paramount importance to the performance of the anemometer.
[0003] However, in the use of existing hot-wire anemometer probe lifting structures, traditional devices rely solely on the rigidity of the telescopic rod itself to maintain stability. When the length of the telescopic rod increases or encounters external interference, it is difficult to ensure that the probe moves accurately in the vertical direction, resulting in a deviation in the relative position of the hot-wire sensor and the airflow. Utility Model Content
[0004] The purpose of this invention is to provide a probe lifting structure for a hot-wire anemometer. By setting up a lifting part, the problem of traditional devices relying solely on the rigidity of the telescopic rod to maintain stability is solved. When the length of the telescopic rod increases or encounters external interference, it is difficult to ensure that the probe moves accurately in the vertical direction, resulting in a deviation in the relative position of the hot-wire sensor and the airflow.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a probe lifting structure for a hot-wire anemometer, comprising a telescopic rod and a connecting block fixed to the top of the telescopic rod, wherein a probe is fixedly connected to the inner wall of the connecting block, and further comprising: a lifting part disposed on the telescopic rod; and a support part mounted on the telescopic rod; wherein the lifting part is located inside the telescopic rod, and the support part is located on the outer wall of the telescopic rod.
[0007] Furthermore, the lifting part includes a power component mounted on the telescopic rod; and a lifting component, wherein a plurality of lifting components are provided, and the plurality of lifting components are disposed on the power component; wherein the plurality of lifting components are connected to each other, the upper lifting component is fixedly connected to the top of the telescopic rod, and the plurality of lifting components are distributed in a linear array.
[0008] Furthermore, the support includes a fixing component mounted on the telescopic rod; and a spreading component disposed on the fixing component.
[0009] Furthermore, the power assembly includes a fixed plate fixedly connected to the inner wall of the bottom of the telescopic rod, a fixed frame fixedly connected to the top of the fixed plate, a hinge assembly one fixedly connected to the top of the fixed plate, an electric telescopic rod fixedly connected to the hinge assembly one, and a hinge assembly two fixedly connected to the side of the electric telescopic rod away from the hinge assembly one, to avoid structural deformation or movement deviation caused by single-point force, thus laying the foundation for the smooth lifting and precise positioning of the probe.
[0010] Furthermore, the lifting assembly includes a hinge rod one hinged to the right side of the fixed frame, the hinge rod one being fixedly connected to a hinge assembly two, the hinge rod one being hinged to the side of the hinge rod one away from the fixed frame, a hinge assembly three being hinged to the front side of the fixed frame, and a connecting plate being hinged to the rear side of the hinge assembly three. The connecting plate has two transmission components; wherein, the length of the hinge assembly three is the same as the combined length of the hinge rod one and the hinge rod two, and the transmission component includes a rotating shaft rotatably connected to the right side of the connecting plate, a gear being fixedly connected to the outer wall of the rotating shaft, and the hinge rod two being fixedly connected to the rotating shaft; wherein, the two gears mesh, solving the problems of easy jamming and inaccurate positioning in traditional single-link structures, and providing reliable mechanical support for high-precision wind speed measurement.
[0011] Furthermore, the fixing component includes a fixing ring fixedly connected to the outer wall of the telescopic rod. Several hinge blocks are fixedly connected to the outer wall of the fixing ring. Each hinge block is hinged with a hinge rod on the side away from the fixing ring. A threaded rod is rotatably connected to the bottom of the telescopic rod, which can flexibly adjust the unfolding angle according to the ground shape, increase the contact area with the ground, and improve the installation efficiency and environmental adaptability of the equipment.
[0012] Furthermore, the spreading assembly includes a sliding ring threaded to the outer wall of the threaded rod. The outer wall of the sliding ring is fixedly connected to a plurality of hinge blocks two. A hinge rod four is hinged to the side of the plurality of hinge blocks two that are far apart from each other. A hinge block three is fixedly connected to the side of the plurality of hinge rod three that are close to each other. The plurality of hinge rod four are respectively hinged to the plurality of hinge blocks three.
[0013] This utility model has the following beneficial effects:
[0014] 1. By setting up a lifting section, after fixing, the electric telescopic rod on the first hinge assembly is activated. When the electric telescopic rod extends, it pushes the second hinge assembly outward. When it is pushed, the first hinge rod will change a certain angle. When the angle changes, the second hinge rod will also change angle accordingly. When the angle of the second hinge rod changes, the rotating shaft will rotate accordingly. When the rotating shaft rotates, the gear will also rotate. At this time, the gear will drive the corresponding gear to rotate. At this time, the rotating shaft will drive the corresponding second hinge rod and the first hinge rod to move. When the rotating shaft moves upward, the connecting plate will rise. When the connecting plate rises, the third hinge assembly will move in coordination. When the upper connecting plate moves, it will drive the telescopic rod to extend upward. When the telescopic rod extends, the connecting block and the probe will also extend accordingly, thereby achieving the lifting effect. The linear movement of the telescopic rod is converted into the smooth vertical lifting and lowering of the probe, which can avoid the shaking and deviation that may occur in the traditional single telescopic structure and ensure the accuracy of the measurement.
[0015] 2. By setting up a support, when it is necessary to fix the telescopic rod, the threaded rod at the bottom is rotated. When the threaded rod rotates, the sliding ring will slide upward on its outer wall. When the sliding ring moves, the second hinge block will also move accordingly. When the second hinge block moves, the fourth hinge rod will push the fourth hinge rod outward. When the fourth hinge rod is pushed outward, it will push the third hinge block and the third hinge rod outward at the same time. At this time, the effect of unfolding the third hinge block can be achieved. Then, the third hinge block is placed on the ground, thereby achieving the effect of fixing the telescopic rod. The unfolded structure forms a multi-point support, which distributes the force like a tripod, effectively resisting external forces such as wind and ground vibration, and ensuring that the telescopic rod is stable and does not shake during the measurement process.

A second hinge assembly 215 is fixedly connected to the side of the electric telescopic rod 214 away from the first hinge assembly 213. The lifting assembly 22 includes a first hinge rod 221 hinged to the right side of the fixed frame 212. The first hinge rod 221 is fixedly connected to the second hinge assembly 215. The second hinge rod 222 is hinged to the side of the first hinge rod 221 away from the fixed frame 212. A third hinge assembly 223 is hinged to the front side of the fixed frame 212. A connecting plate 224 is hinged to the rear side of the third hinge assembly 223. The connecting plate 224 is provided with… There are two transmission components; among them, the length of the third hinge assembly 223 is the same as that of the first hinge rod 221 and the second hinge rod 222 combined. The transmission component includes a rotating shaft 225 rotatably connected to the right side of the connecting plate 224. A gear 226 is fixedly connected to the outer wall of the rotating shaft 225. The second hinge rod 222 is fixedly connected to the rotating shaft 225. The two gears 226 mesh with each other.

[0028] The support part 3 includes a fixing component 31, which is mounted on the telescopic rod 111; and a spreading component 32, which is disposed on the fixing component 31. The fixing component 31 includes a fixing ring 311 fixedly connected to the outer wall of the telescopic rod 111. A plurality of hinge blocks 312 are fixedly connected to the outer wall of the fixing ring 311. Each of the hinge blocks 312 is hinged to a hinge rod 313 on the side away from the fixing ring 311. A threaded rod 314 is rotatably connected to the bottom of the telescopic rod 111. The spreading component 32 includes a threaded connection to the threaded rod 314. The sliding ring 321 of the wall has several hinge blocks 322 fixedly connected to its outer wall. Each hinge block 322 has a hinge rod 323 hinged to its opposite side.

[0029] A specific application of this embodiment is as follows: In use, the telescopic rod 111 must first be fixed. While fixing, rotate the threaded rod 314 at the bottom. As the threaded rod 314 rotates, the sliding ring 321 slides upwards on its outer wall. When the sliding ring 321 moves, the hinge block 322 also moves accordingly. When the hinge block 322 moves, the hinge rod 323 pushes outwards. When the hinge rod 323 is pushed outwards, it simultaneously pushes the hinge block 324 and the hinge rod 313 outwards, thus unfolding the hinge block 324. The hinge block 324 is then placed on the ground, thereby fixing the telescopic rod 111. After fixing, activate the electric telescopic rod 214 on the hinge assembly 213. When the electric telescopic rod 214 extends, it pushes the hinge assembly 215 outwards. When the hinge rod 221 is pushed, its angle changes. This angle change causes the hinge rod 222 to also change angle. As the hinge rod 222 changes angle, the rotating shaft 225 rotates. When the rotating shaft 225 rotates, the gear 226 also rotates, causing the corresponding gear 226 to rotate. This causes the rotating shaft 225 to move along with the hinge rods 222 and 221. When the rotating shaft 225 moves upward, the connecting plate 224 rises. As the connecting plate 224 rises, the hinge assembly 223 moves accordingly. The movement of the connecting plate 224 causes the telescopic rod 111 to extend upward. When the telescopic rod 111 extends, the connecting block 112 and the probe head 113 also extend, thus achieving a lifting effect.
