Description
Technical Field
[0001] This utility model belongs to the field of sensor protection technology, specifically a frost-proof self-regulating protective shell for meteorological sensors. Background Technology
[0002] Meteorological sensors are core components used to measure the meteorological environment and are widely used in meteorological research, environmental monitoring, agriculture, environmental protection and other fields. These sensors can monitor various meteorological elements in real time, including wind speed, wind direction, temperature, humidity, atmospheric pressure, rainfall, light intensity and air quality, providing key data for weather forecasting, environmental assessment and agricultural production.
[0003] However, meteorological sensors face severe challenges in low-temperature and frost environments. Frost can not only cause ice to form on the sensor surface, affecting its measurement accuracy and sensitivity, but may also damage internal components of the sensor, resulting in missing or incorrect observation data. In particular, meteorological sensors are more susceptible to the effects of frost in high-altitude and high-humidity areas.
[0004] Therefore, a protective shell is needed to prevent weather sensors from being damaged by frost, thus helping them avoid damage caused by harsh environments. Utility Model Content
[0005] To address the problems mentioned in the background section, this invention provides a frost-resistant, self-regulating protective shell for meteorological sensors.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a frost-proof self-regulating protective shell for a weather sensor, comprising a connecting base, a weather sensor body fixed to the top of the connecting base, a first protective plate disposed inside the connecting base, a second protective plate disposed inside the connecting base, a rotating mechanism disposed at one end of the first and second protective plates, a winding mechanism disposed outside the first and second protective plates, and a heating wire fixed inside the first and second protective plates;
[0007] The rotating mechanism includes a first connecting rod, a first gear, and a micro servo motor. The first connecting rod is fixed inside the first protective plate, and a micro servo motor is fixed to one end of the first connecting rod and to the outside of the first connecting rod. A second connecting rod is fixed inside the second protective plate, and a second gear is fixed to the outside of the second connecting rod.
[0008] Preferably, the outer wall of the first connecting rod is close to the inner wall of the connecting seat, the first connecting rod and the connecting seat are rotatably connected, and the micro servo motor is fixed inside the connecting seat.
[0009] Preferably, the outer wall of the second connecting rod is close to the inner wall of the connecting seat, the second connecting rod and the connecting seat are rotatably connected, and the outer walls of the first gear and the micro servo motor are provided with several sets of equally spaced teeth, and the first gear and the micro servo motor are meshed together.
[0010] Preferably, the winding mechanism includes a first limiting rod, a first limiting groove, and a second limiting rod. The first limiting rod is fixed to the outside of the first protective plate and the second protective plate. The first limiting groove is formed inside the first protective plate and the second protective plate. The second limiting rod is fixed to the outside of the first protective plate and the second protective plate. The second limiting groove is formed inside the first protective plate and the second protective plate. A first clamping plate is provided inside the first protective plate and the second protective plate. A second clamping plate is provided inside the first protective plate and the second protective plate.
[0011] Preferably, the first limiting rod and the first limiting groove are provided with two sets of symmetrically distributed about the central axes of the first protective plate and the second protective plate, and the second limiting rod and the second limiting groove are provided with two sets of symmetrically distributed about the central axes of the first protective plate and the second protective plate.
[0012] Preferably, the outer wall of the first clamping plate is close to the inner wall of the first protective plate or the second protective plate, and the first clamping plate and the first protective plate or the second protective plate are slidably connected. The outer wall of the second clamping plate is close to the inner wall of the first protective plate or the second protective plate, and the second clamping plate and the first protective plate or the second protective plate are slidably connected.
[0013] Preferably, the first and second protective plates are symmetrically distributed about the central axis of the connecting seat, and several groups of heating wires are provided, with the heating wires being equally spaced about the central axis of the first or second protective plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This invention, through the coordinated arrangement of a first connecting rod, a first gear, and a micro servo motor, enables the device to rotate by activating the micro servo motor, thereby rotating the first connecting rod and the first gear, which in turn rotates the first protective plate. The meshing of the first and second gears further rotates the second gear, which in turn rotates the second connecting rod and the second protective plate. The first and second protective plates rotate in opposite directions, allowing them to unfold and close. When unfolded, this increases the space between the meteorological sensor body and the external environment, improving meteorological monitoring. In frosty conditions, the device is adjusted to a closed state, and a heating wire is activated to generate heat, thus providing constant temperature heating to the meteorological sensor body and preventing damage from frost. This achieves the purpose of facilitating freeze protection for the meteorological sensor body. Furthermore, since the meteorological sensor body can detect the surrounding temperature environment, it can automatically control the opening and closing of the first and second protective plates, prioritizing either accuracy or freeze protection when a preset environment is reached.
[0016] This invention, through the combination of a first limiting rod, a first limiting groove, and a second limiting rod, allows the device to thread the insulation cloth through the first limiting rod, the first limiting groove, the second limiting rod, and the second limiting groove via a backpack strap. After adjusting to a suitable length, the cloth is then threaded through the other end of the first limiting rod, the first limiting groove, the second limiting rod, and the second limiting groove. The middle section of the insulation cloth is then clamped by the first and second clamping plates, thus fixing the insulation cloth to the inner wall of the first or second protective plate. This allows the insulation cloth to retain more heat, resulting in better antifreeze performance. Furthermore, the insulation cloth can be replaced after wear and tear, extending the lifespan of the protection system. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figures 1 to 7 As shown, this utility model provides a frost-proof self-regulating protective shell for a meteorological sensor, including a connecting base 1, a meteorological sensor body 2 fixed to the top of the connecting base 1, a first protective plate 3 and a second protective plate 4 disposed inside the connecting base 1, a rotating mechanism 5 disposed at one end of the first protective plate 3 and the second protective plate 4, a winding mechanism 6 disposed outside the first protective plate 3 and the second protective plate 4, and heating wires 7 fixed inside the first protective plate 3 and the second protective plate 4, the first protective plate 3 and the second protective plate 4 being symmetrically distributed about the central axis of the connecting base 1, and several groups of heating wires 7 being disposed at equal intervals about the central axis of the first protective plate 3 or the second protective plate 4.
[0027] like Figures 1 to 7As shown, the rotating mechanism 5 includes a first connecting rod 501, a first gear 502, and a micro servo motor 503. The first connecting rod 501 is fixed inside the first protective plate 3. The micro servo motor 503 is fixed at one end of the first connecting rod 501 and at the outside of the first connecting rod 501. The outer wall of the first connecting rod 501 is close to the inner wall of the connecting seat 1. The first connecting rod 501 and the connecting seat 1 are rotatably connected. The micro servo motor 503 is fixed inside the connecting seat 1. The second connecting rod 504 is fixed inside the second protective plate 4. The second gear 505 is fixed at the outside of the second connecting rod 504. The outer wall of the second connecting rod 504 is close to the inner wall of the connecting seat 1. The second connecting rod 504 and the connecting seat 1 are rotatably connected. The outer walls of the first gear 502 and the micro servo motor 503 are provided with several sets of equally spaced teeth. The first gear 502 and the micro servo motor 503 are meshed together.
[0028] The above scheme is adopted as follows: by starting the micro servo motor 503, the first connecting rod 501 and the first gear 502 are rotated, which in turn drives the first protective plate 3 to rotate. Through the meshing of the first gear 502 and the second gear 505, the second gear 505 is rotated, which in turn drives the second connecting rod 504 and the second protective plate 4 to rotate. The rotation directions of the first protective plate 3 and the second protective plate 4 are opposite, so that the first protective plate 3 and the second protective plate 4 can be opened and closed. When opened, the space in contact between the meteorological sensor body 2 and the external environment can be expanded, thereby improving the effect of meteorological monitoring. In the frost environment, it is adjusted to the closed state and the heating wire 7 is activated to generate heat, thereby heating the meteorological sensor body 2 at a constant temperature and preventing the meteorological sensor body 2 from being damaged by the frost.
[0029] like Figures 1 to 7 As shown, the winding mechanism 6 includes a first limiting rod 601, a first limiting groove 602, and a second limiting rod 603. The first limiting rod 601 is fixed to the outside of the first protective plate 3 and the second protective plate 4. The first limiting groove 602 is opened inside the first protective plate 3 and the second protective plate 4. The second limiting rod 603 is fixed to the outside of the first protective plate 3 and the second protective plate 4. The second limiting groove 604 is opened inside the first protective plate 3 and the second protective plate 4. The first limiting rod 601 and the first limiting groove 602 are symmetrically distributed about the central axis of the first protective plate 3 and the second protective plate 4. The second limiting rod 603 and the second limiting groove 604 are symmetrically distributed about the central axis of the first protective plate 3 and the second protective plate 4.
[0030] like Figures 1 to 7As shown, a first clamping plate 605 is provided inside the first protective plate 3 and the second protective plate 4, and a second clamping plate 606 is provided inside the first protective plate 3 and the second protective plate 4. The outer wall of the first clamping plate 605 is close to the inner wall of the first protective plate 3 or the second protective plate 4, and the first clamping plate 605 and the first protective plate 3 or the second protective plate 4 are slidably connected. The outer wall of the second clamping plate 606 is close to the inner wall of the first protective plate 3 or the second protective plate 4, and the second clamping plate 606 and the first protective plate 3 or the second protective plate 4 are slidably connected.
[0031] Using the above method: the thermal insulation cloth is inserted through the first limiting rod 601, the first limiting groove 602, the second limiting rod 603 and the second limiting groove 604 via the backpack strap and adjusted to a suitable length. Then, it is inserted through the other end of the first limiting rod 601, the first limiting groove 602, the second limiting rod 603 and the second limiting groove 604. The middle section of the thermal insulation cloth is then clamped by the first clamping plate 605 and the second clamping plate 606. At this time, the thermal insulation cloth can be fixed to the inner wall of the first protective plate 3 or the second protective plate 4.
[0032] The working principle and usage of this utility model are as follows: The micro servo motor 503 is activated to rotate the first connecting rod 501 and the first gear 502, which in turn rotates the first protective plate 3. The meshing of the first gear 502 and the second gear 505 then rotates the second gear 505, which in turn rotates the second connecting rod 504 and the second protective plate 4. The first and second protective plates 3 and 4 rotate in opposite directions, allowing them to unfold and close. When unfolded, the space between the meteorological sensor body 2 and the external environment is expanded, thereby improving the meteorological monitoring effect. In frosty conditions, the sensor body 2 is closed, and the heating wire 7 is activated to generate heat, thus providing constant temperature heating and preventing damage from frost. This facilitates meteorological monitoring. The sensor body 2 is designed for freeze protection. Since the meteorological sensor body 2 can detect the surrounding temperature environment, it can automatically control the opening and closing of the first protection plate 3 and the second protection plate 4 when the preset environment is reached, prioritizing either accuracy or freeze protection. The device can also insert the insulation cloth through the backpack strap into the first limiting rod 601, the first limiting groove 602, the second limiting rod 603 and the second limiting groove 604 and adjust it to a suitable length. Then, it can be inserted into the other end of the first limiting rod 601, the first limiting groove 602, the second limiting rod 603 and the second limiting groove 604. The middle section of the insulation cloth is clamped by the first clamping plate 605 and the second clamping plate 606. At this time, the insulation cloth can be fixed to the inner wall of the first protection plate 3 or the second protection plate 4, thereby retaining more heat through the material of the insulation cloth, making the freeze protection effect better.
