Description

Technical Field

[0001] The utility model relates to the field of wind speed measuring devices, in particular to an outdoor wind speed measuring device. Background Art

[0002] Outdoor wind speed measuring device refers to the equipment used to measure the wind speed and related meteorological parameters in the natural environment. It is mainly used in meteorological observation, environmental science research, aviation and navigation, wind energy forecasting, sports (such as sailing, paragliding, kite surfing, paragliding), agriculture (such as spraying, irrigation), wind power generation and other fields. This type of device can be divided into different types according to the measurement principle and technology. Among them, the hot wire anemometer uses the principle of thermistor hot wire. When the wind blows through the hot wire, it takes away the heat, the resistance changes, and the current change is measured to calculate the wind speed. The advantages are fast response and high accuracy, but care must be taken to protect the probe from being fragile.

[0003] Existing hot wire anemometers are generally designed with an integrated structure. In actual applications, the integrated design makes the probe directly exposed to the outside when not in use. Even when not in operation, it is susceptible to damage from accidental collisions or severe weather conditions, such as wind and rain erosion. This not only shortens the life of the probe, but may also lead to a decrease in measurement inaccuracy. In addition, since the probe is directly exposed to the outside, it is inconvenient to maintain and store. The probe status needs to be checked separately before and after each use, which increases the complexity of the operation. If the problem is not discovered in time, it may lead to measurement failure in the next use.

[0004] Therefore, it is necessary to provide a new outdoor wind speed measuring device to solve the above-mentioned technical problems. Utility Model Content

A protective sleeve 4 is fixedly connected to the upper end of one side of the speed measuring body 1, and the end of the probe 3 can extend into a protective ring groove opened at the bottom of the protective sleeve 4. The protective sleeve 4 is used to protect the end of the probe 3 and limit its horizontal angle. The protective sleeve 4 is fixed on one side of the body, and the probe 3 extends into the groove at the bottom of the protective sleeve 4. Such a design not only provides physical protection for the probe 3 to prevent accidental collision damage, but also limits the horizontal movement range. The protective measures of the protective sleeve 4 and the probe 3 reduce direct exposure, reduce the risk of injury, and extend the outdoor use cycle, which is suitable for long-term field operations;

[0022] A plurality of annular grooves are provided on the probe 3, and a fixing component is also provided at the lower end of one side of the speed measuring body 1. The fixing component can be placed in the annular groove of the probe 3 and limit its vertical angle. A plurality of annular grooves are provided on the probe 3, and these grooves are designed to receive the fixing components to ensure the stability of the probe 3 in the horizontal and vertical directions. Through component positioning, the fixing component provided at the lower end of the speed measuring body 1 can be inserted into the annular groove of the probe 3 to limit the vertical angle.

[0023] The fixing assembly includes a fixing plate 5 fixedly connected to the lower end of one side of the speed measuring body 1, the fixing plate 5 is rotatably connected to a rotating rod 6, the outer wall of the rotating rod 6 is fixedly connected to a connecting rod 8, and the end of the connecting rod 8 away from the rotating rod 6 is fixedly connected to a limiting plate 9, and a semicircular rectangular groove matching the circular groove of the probe 3 is opened on the limiting plate 9, and the limiting plate 9 can be rotated to the circular groove of the probe 3 with the rotating rod 6 as the center, and the limiting plate 9 is opened with a semicircular rectangular groove matching the circular groove of the probe 3 to ensure that the probe 3 The position is firmly fixed, and the limit plate 9 can rotate around the center of the rotating rod 6. By adjusting the angle of the probe 3, fine-tuning calibration in the horizontal or vertical direction is achieved. A plurality of trapezoidal blocks 7 are fixedly connected to the top of the rotating rod 6 at equal intervals along the circumferential direction. The trapezoidal blocks 7 are inclined from the top of the rotating rod 6 to the bottom of the outer side thereof. A fixed plate 2 10 is fixedly connected to the fixed plate 1 5, and a sliding rod 11 is slidably connected to the fixed plate 2 10. The top of the sliding rod 11 is fixedly connected to a limited end cover 13, and a plurality of inner bottom walls of the limited end cover 13 are provided with a plurality of trapezoidal blocks 7. The shape and structure of the inclined groove 14 are matched, and a plurality of trapezoidal blocks 7 are fixed on the top of the rotating rod 6, which are inclinedly distributed on the outside thereof along the circumference. The trapezoidal blocks 7 are designed to match the circular groove of the probe 3. When the rotating rod 6 is rotated for adjustment, the trapezoidal blocks 7 are embedded in the groove of the probe 3 to achieve fine angle fixation of the probe 3. A telescopic spring 12 is arranged on the outer wall of the sliding rod 11. The upper and lower ends of the telescopic spring 12 are respectively fixedly connected to the top of the fixed plate 10 and the bottom of the limit end cover 13.

The upper and lower ends of the spring are respectively connected to the top of the fixed plate 10 and the limit end cover 13. This spring provides the necessary restoring force to ensure that the structure is stable after adjustment. Even if the external force is released, it can be restored to the preset position by the spring to maintain the set position.

[0024] The working principle provided by the utility model is as follows: during the specific implementation of the utility model, first, when the probe 3 does not need to be stored or is temporarily not working, it is vertically slid into the protective ring groove of the protective sleeve 4 to provide physical protection for the probe 3 and avoid damage caused by external collisions and environmental factors. Next, the operator applies force to the limit end cover 13 to trigger the telescopic spring 12. Under the force of the telescopic spring 12, the bottom of the limit cover moves, and the oblique groove 14 thereon is disengaged from the trapezoidal block 7 on the rotating rod 6, releasing the rotating rod 6 and the limit, so that the probe 3 can now be freely rotated and adjusted. After the limit is released, the operator can rotate the limit plate 9 to align the semicircular rectangular groove thereon with the circular groove on the probe 3 to ensure that the probe 3 is accurately positioned horizontally and vertically, and prepare for the subsequent working state. The semicircular rectangular groove of the limit plate 9 is engaged with the circular groove of the probe 3 to limit the horizontal and vertical angles of the probe 3. This state not only provides accurate positioning for the probe 3, but also ensures protection when not working, avoids unnecessary movement or accidental touch damage, and extends the service life.
