Description

Technical Field

[0001] This utility model relates to the field of observation assistance technology, and in particular to an observation assistance device. Background Technology

[0002] With the continuous development of technology, observation heads, as devices capable of accurately capturing, recording, or transmitting information about target areas, are widely used in various fields such as astronomical detection, meteorological monitoring, environmental monitoring, and traffic monitoring due to their diverse types (such as optical, electronic, and infrared) and highly customizable characteristics. However, due to their specific observation needs (such as meteorological monitoring and traffic monitoring), some observation heads are in direct contact with the external environment, easily accumulating dust, dew, rainwater, and snowflakes, which can affect the accuracy of the observation data.

[0003] Chinese patent application CN213872031U, entitled "A Safety Monitoring Device for Water Conservancy Projects," includes a base, a lifting device, and a cleaning device. The cleaning device includes a top plate with a right-angle rod at its bottom. A driven shaft is rotatably connected to the right-angle rod via a bearing. A brush is mounted on the outer wall of the top of the driven shaft. The brush is fitted into the outer wall of the monitoring probe. This device uses the driven shaft to drive the brush to wipe and clean the outer wall of the monitoring probe, preventing dust from affecting the monitoring hydrological data. However, this technical solution only considers the impact of dust on the probe's measurement data and does not consider other factors affecting the probe. As the probe is used over time, it operates in different seasons and weather conditions. Morning dew, rainwater from heavy rains, and even snow and frost in winter can adhere to the probe, further weakening the visible field of view and potentially preventing the provision of clear observation images and accurate data to personnel. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to clean water stains and frost on the lens of the observation head, and reduce the impact of rain and snow on the accuracy of the observation image and observation data.

[0005] The technical solution adopted by this utility model to solve its technical problem is: The observation aid device includes a base and an L-shaped frame mounted on the base. The L-shaped frame includes a horizontal plate and a vertical frame connected to the base. A wireless probe that can rotate around its own circumference is installed on the inner side of the horizontal plate. The vertical frame is equipped with a drive mechanism. The drive mechanism is connected to a cleaning head that can abut against the lens of the wireless probe. The cleaning head includes a heating plate, a heat-resistant elastic element, and an absorbent cloth connected in sequence. The absorbent cloth abuts against the lens of the wireless probe.

[0006] Furthermore, a controller and a wireless signal transmission module electrically connected to the wireless probe are installed inside the L-shaped frame. The drive mechanism, the heating plate, the wireless signal transmission module, and the wireless probe are all electrically connected to the controller.

[0007] Furthermore, the aforementioned vertical frame is fixedly equipped with a mounting plate, and the driving mechanism includes a ball rotatably mounted on the mounting plate. One end of the ball passes through the mounting plate and is fixedly connected to a connecting rod, while the other end passes through the mounting plate and is fixedly connected to a power rod. The end of the power rod away from the ball is hinged to an electric push rod mounted on the vertical frame. The electric push rod is electrically connected to the aforementioned controller, and the swing end of the connecting rod is connected to the cleaning head.

[0008] Furthermore, a support plate is provided between the aforementioned connecting rod and the aforementioned cleaning head, and at least two telescopic rods are provided between the support plate and the mounting plate. The telescopic end of the telescopic rod is hinged to the aforementioned support plate, and the other end is hinged to the mounting plate.

[0009] Furthermore, a contact switch electrically connected to the electric push rod is installed at the free end of the aforementioned transverse plate, and a push rod is fixed on the ring side of the wireless probe. The push rod rotates circumferentially with the wireless probe to trigger the contact switch.

[0010] Furthermore, the heating plate and the heat-resistant elastic element are connected by a pair of magnetic blocks that attract each other. One of the magnetic blocks is embedded in the side of the heating plate near the heat-resistant elastic element, and the other is located inside the heat-resistant elastic element.

[0011] Furthermore, the aforementioned heat-resistant elastic component has an inwardly recessed arc-shaped surface on the side near the wireless probe.

[0012] Furthermore, a fixed cylinder is fixedly connected to the upper end face of the base, and a lifting rod is longitudinally slidably provided inside the fixed cylinder. The L-shaped bracket is mounted on the upper end face of the lifting rod, and a screw sleeve is rotatably provided on the fixed cylinder. The screw sleeve is fitted onto the lifting rod and cooperates with its lifting movement.

[0013] Furthermore, the aforementioned screw sleeve is fixedly fitted with a worm gear, and a worm is rotatably provided on the outside of the fixed cylinder to mesh with the aforementioned worm gear.

[0014] Furthermore, a pair of guide blocks are fixedly provided on the side of the lifting rod ring near the bottom of the fixed cylinder, and a pair of guide grooves are opened opposite each other on the side of the fixed cylinder ring, with the pair of guide blocks slidingly disposed in the pair of guide grooves respectively.

[0015] The beneficial effects of this utility model are as follows: The observation auxiliary device has an L-shaped frame on the base, a wireless probe is installed inside the L-shaped frame, and a swinging cleaning head is installed in conjunction with it. The cleaning head is equipped with a heating plate, a heat-resistant elastic component, and an absorbent cloth. The heat-resistant elastic component and the absorbent cloth enable the swinging cleaning head to better fit and contact the lens surface of the wireless probe, thereby completing the wiping of the lens of the wireless probe. At the same time, the addition of a heating plate not only keeps the cleaning head in a dry and good wiping state before wiping, but also dries the water stains on the lens of the observation head, and melts the frost and snow on the lens surface, reducing the impact of rain and snow on the observation image and the accuracy of the observation data of the wireless probe.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings. It should be noted that the wireless probe 5 can observe a wide range of data; this embodiment uses airport weather observation data as an example.

[0019] like Figures 1-8As shown, the red line represents the outline of the lens of the wireless probe 5, and the green line represents the outline of the cleaning head 7 before deformation. This observation aid includes a base 1 and an L-shaped frame 2 mounted on the base 1. The L-shaped frame 2 includes a horizontal plate 3 and a vertical frame 4 connected to the base 1. The wireless probe 5, which can rotate circumferentially, is mounted inside the horizontal plate 3. The vertical frame is equipped with a drive mechanism, which is connected to a cleaning head 7 that abuts against the lens of the wireless probe 5. The cleaning head 7 includes a heating plate 8, a heat-resistant elastic element 9, and an absorbent cloth 10 connected in sequence. The absorbent cloth 10 abuts against the lens of the wireless probe 5.

[0020] The absorbent cloth 10 is made of high-temperature resistant microfiber cloth, a special fabric made from microfiber. Due to its extremely fine fineness, microfiber significantly reduces the stiffness of the fibers, resulting in an extremely soft hand feel. The fineness of the fibers also increases the layered structure of the fibers, increasing the specific surface area (specific surface area is a core parameter in materials science, referring to the total surface area per unit mass of a substance, usually measured in square meters per gram (m² / g). It directly reflects the contact efficiency between the material and the external environment (such as gases, liquids, catalysts, etc.) and is a key indicator for measuring the adsorption, catalysis, filtration, and heat conduction properties of materials), and capillary effect. This makes the reflected light inside the fiber more finely distributed on the surface, giving it an elegant luster like silk and excellent moisture absorption and dissipation properties. Because microfiber is both fine and soft, it is excellent for cleaning cloths, capable of wiping various eyeglasses, audio-visual equipment, and precision instruments without damaging the mirror surface. The heat-resistant elastic component 9 can be a high-temperature resistant rubber component or a high-temperature resistant sponge component; preferably, a high-temperature resistant sponge component is used as the heat-resistant elastic component 9. The high-temperature resistant sponge component not only has high elasticity but also a certain degree of water absorption, which can help the absorbent cloth 10 to better clean water stains on the lens surface of the wireless probe 5. The absorbent cloth 10 can be fixedly connected to the heat-resistant elastic component 9 using high-temperature resistant adhesive. When the heat-resistant elastic component 9 is a high-temperature resistant rubber component, a high-temperature resistant rubber adhesive can be used; when the heat-resistant elastic component 9 is a high-temperature resistant sponge component, a sponge bonding adhesive can be used. Alternatively, GY-8018 high-temperature resistant high-strength special adhesive can also be used. Preferably, the absorbent cloth 10 can also completely wrap the heat-resistant elastic component 9. After wrapping, it can be sewn with needle and thread, and excess fabric can be cut off, thereby improving the adhesion between the absorbent cloth 10 and the heat-resistant elastic component 9.

[0021] When lens cleaning is required (in rainy, snowy, or dewy weather), the heating plate 8 is activated first. After the heating plate 8 is activated, it transfers heat to the heat-resistant elastic component 9 and the absorbent cloth 10 through thermal radiation and conduction, thus drying them. Once dry, the preparation is complete. The wireless probe 5 begins to rotate. When the lens of the wireless probe 5 rotates to the cleaning head 7, the drive mechanism is activated, causing the cleaning head 7 to press against the lens of the wireless probe 5. This, combined with the circumferentially rotating wireless probe 5, completes the wiping of the lens. If cleaning the circumference of the wireless probe 5 is required, the drive mechanism simply needs to remain activated, keeping the cleaning head 7 in contact with the lens of the wireless probe 5 until the wireless probe 5 has rotated one full circle. Of course, if cleaning the circumferential sides of the wireless probe 5 is desired, a cleaning head 7 of appropriate size needs to be selected based on the actual situation. It should be noted that when the lens of the wireless probe 5 is frosted or there is rain or snow, the rotation speed of the wireless probe 5 can be slowed down or even stopped intermittently. At the same time, the heating plate 8 is always on during the cleaning process of the cleaning head 7.

[0022] Compared to current observation auxiliary devices that can only clean dust, this design can wipe and dry water stains, frost, snow, or dust on the outside of the lens of the wireless probe 5 (or the ring side of the wireless probe 5), thereby cleaning the water stains on the lens of the wireless probe 5. This can, to some extent, avoid the problem of unclear vision of the wireless probe 5 caused by rain and snow, enabling the equipment to conduct normal observations in inclement weather such as rain and snow, and providing more accurate weather observation information.

[0023] The L-shaped frame 2 has a controller 17 and a wireless signal transmission module 18 electrically connected to the wireless probe 5 installed inside. The heating plate 8, the wireless signal transmission module 18, and the wireless probe 5 are all electrically connected to the controller 17. The controller 17 is the core component of the electronic device or system, responsible for receiving input signals, processing logic instructions, and outputting control signals to manage other devices or perform specific tasks. Essentially, it is a "decision-making center," coordinating hardware operation through preset programs or external instructions. The wireless signal transmission module 18 is an electronic device that uses wireless technology to transmit data. The wireless signal transmission module 18 can remotely transmit meteorological observation information of the surrounding environment from the wireless probe 5, providing a certain degree of convenience and accuracy for weather observation. By setting up the controller 17 and connecting the drive mechanism, heating plate 8, wireless signal transmission module 18, and wireless probe 5 to the controller 17, remote control of the observation auxiliary device can be achieved. That is, the wireless signal transmission module 18 receives and processes instructions, and then transfers the corresponding signals to the controller 17. The controller 17 can start and stop the drive mechanism, the wireless probe 5, and the heating plate 8, thereby achieving a certain degree of remote control.

[0024] The aforementioned vertical frame 4 is fixedly mounted with a mounting plate 11. The aforementioned drive mechanism includes a ball 12 rotatably mounted on the mounting plate 11. One end of the ball 12 passes through the mounting plate 11 and is fixedly connected to a connecting rod 6. The other end of the ball 12 passes through the mounting plate 11 and is fixedly connected to a power rod 13. The end of the power rod 13 away from the ball 12 is hinged to an electric push rod 14 mounted on the vertical frame 4. The electric push rod 14 is electrically connected to the aforementioned controller 17. The swing end of the connecting rod 6 is connected to the aforementioned cleaning head 7. (Reference) Figure 1 In the following text, "up and down," "clockwise," and "counterclockwise" all refer to... Figure 1 The orientation shown is for reference, where the "up and down" direction is consistent with the central axis of the wireless probe 5. When cleaning of the wireless probe 5 (including the lens and the surrounding surface of the wireless probe 5) is required, the controller 17 controls the electric push rod 14 to start. The electric push rod 14 extends, pushing the hinged power rod 13 to swing upward. The ball 12 is pushed and begins to rotate clockwise. The connecting rod 6 swings downward, causing the cleaning head 7, which is attached to the wireless probe 5, to swing downward, completing the downward wiping of the lens of the wireless probe 5. The electric push rod 14 retracts, causing the hinged power rod 13 to swing downward. The ball 12 is pulled and begins to rotate counterclockwise. The connecting rod 6 swings upward, causing the cleaning head 7, which is attached to the wireless probe 5, to wipe upward. Although the trajectory of the cleaning head 7 during the reciprocating swing is arc-shaped, and the lens of the wireless probe 5 is also arc-shaped, the heat-resistant elastic element 9 has a certain deformation capacity. Therefore, during the swing of the cleaning head 7, the cleaning head 7 will undergo a certain degree of deformation to complete the contact with the lens surface of the wireless probe 5. Proper contact facilitates the cleaning of the lens of the wireless probe 5 by the cleaning head 7. This design utilizes the coordinated action of the ball 12, connecting rod 6, and power rod 13, ultimately achieving the swinging of the cleaning head 7 via the extension and retraction of the electric push rod 14, thus completing the cleaning of the lens of the wireless probe 5. This design automates the cleaning of the lens of the wireless probe 5, saving manpower. Furthermore, this design controls the swinging frequency and amplitude of the cleaning head 7 by adjusting the extension and retraction frequency and value of the electric push rod 14.

[0025] Preferably, a support plate 28 is provided between the connecting rod 6 and the cleaning head 7. At least two telescopic rods 15 are provided between the support plate 28 and the mounting plate 11. The telescopic end of each telescopic rod 15 is hinged to the support plate 28, and the other end is hinged to the mounting plate 11. Each telescopic rod 15 consists of two hollow cylindrical tubes, with the telescopic function achieved through the connection of the inner and outer tubes. The outer tube is hinged to the mounting plate 11, and one end of the inner tube slides through the outer tube, while the other end is hinged to the support plate 28. In this design, the telescopic rods 15 and the support plate 28 provide a certain degree of support for the cleaning head 7.

[0026] Furthermore, a contact switch 19 electrically connected to the electric push rod 14 is installed at the free end of the aforementioned transverse plate 3, and a push rod 20 is fixedly provided on the circumferential side of the wireless probe 5. The push rod 20 rotates circumferentially with the wireless probe 5 to trigger the contact switch 19.

[0027] The contact switch 19 is an electrical component that achieves circuit switching through physical contact. Its core principle is that the contacts close or open under mechanical force, thereby controlling the flow of current. The wireless probe 5 includes a mounting base and a probe body. The probe body is rotatably mounted on the mounting base (the rotation of the wireless probe 5 is existing technology and will not be described in detail here). The mounting base is fixedly mounted on the inner side of the horizontal plate 3, and the push rod 20 is located on the probe body near the mounting base. When the wireless probe 5 rotates circumferentially, that is, when the probe body rotates on the mounting base, it drives the push rod 20 to rotate. The lens of the wireless probe 5 begins to contact the cleaning head 7. The probe body continues to rotate, and after the lens of the wireless probe 5 separates from the cleaning head 7, that is, after passing the cleaning head 7, the push rod 20 rotates to the position that triggers the contact switch 19. The contact switch 19 controls the electric push rod 14 to open. Then the probe body rotates in the opposite direction, and the lens of the wireless probe 5 rotates in the opposite direction and gradually contacts the oscillating cleaning head 7. The cleaning head 7 wipes the lens of the wireless probe 5. After the wireless probe 5 rotates to a preset angle (this angle is less than 180 degrees and can be preset in the controller 17), the first wiping of the lens is completed. The wireless probe 5 changes its rotation direction again to perform a second wiping, until the push rod 20 triggers the contact switch 19 for the second time, the electric push rod 14 stops working, and the cleaning is completed. Then the wireless probe 5 changes its rotation direction for the third time, and the lens of the wireless probe 5 rotates to the working position to start working, waiting for the next cleaning.

[0028] The heating plate 8 and the heat-resistant elastic component 9 are connected by a pair of mutually attracting magnetic blocks 16. One of the magnetic blocks 16 is embedded in the side of the heating plate 8 near the heat-resistant elastic component 9, and the other is located inside the heat-resistant elastic component 9. The heat-resistant elastic component 9 has a placement cavity, and the corresponding magnetic block 16 is located within the placement cavity. An installation port communicating with the placement cavity is opened on the side of the heat-resistant elastic component 9 near the heating plate 8, allowing personnel to insert the magnetic block 16 into the placement cavity through the installation port. Multiple magnetic blocks 16 can be used, arranged in pairs, with installation ports on the heat-resistant elastic component 9 corresponding to the pairs of magnetic blocks 16. After a period of use, i.e., when the absorbent cloth 10 of the cleaning head 7 and the heat-resistant elastic component 9 become dirty (i.e., the high-temperature resistant microfiber cloth becomes dirty), the heat-resistant elastic component 9, fixed by the pair of magnetic blocks 16, can be quickly disassembled and replaced with a new heat-resistant elastic component 9 with the absorbent cloth 10. This design speeds up the installation and disassembly time of the heat-resistant elastic component 9 on the cleaning head 7, and the installation and disassembly are also relatively simple. The heat-resistant elastic component 9 with absorbent cloth 10 that has been removed can be washed and reused, which can reduce costs.

[0029] like Figures 4-5 As shown, the contact surface between the heat-resistant elastic element 9 and the wireless probe 5 can be an inclined surface, meaning the thickness of the heat-resistant elastic element gradually increases along the axial direction of the wireless probe 5, with the thickness of the heat-resistant elastic element 9 being greater closer to the free end of the wireless probe 5. Since the absorbent cloth 10 is attached to the surface of the heat-resistant elastic element 9, the contact surface between the cleaning head 7 and the wireless probe 5 is also an inclined surface. Figure 4 This is the positional relationship between the cleaning head 7 and the lens of the wireless probe 5 when the electric push rod 14 is in its initial state (which is also the lowest state of the cleaning head 7 during the swing process). The green line is the shape of the cleaning head 7 before deformation, and the red line is the outline of the lens on the wireless probe 5. Figure 5 This shows the state when the cleaning head 7 is at its maximum position. The green line represents the shape of the cleaning head 7 before deformation, and the red line represents the outline of the lens of the wireless probe 5. From this, we can see... Figures 4-5 These are the two states of the cleaning head 7 reciprocating. This design ensures that while the wireless probe 5 rotates and the cleaning head 7 swings, the wiping coverage of the cleaning head 7 can encompass the entire lens surface of the wireless probe 5. Preferably, as... Figures 1-3 The green line represents the shape of the cleaning head 7 before deformation, and the red line represents the outline of the lens on the wireless probe 5. The heat-resistant elastic element 9 has an inwardly concave, curved surface on the side closest to the wireless probe 5. That is, the surface where the cleaning head 7 contacts the wireless probe 5 is also a concave, curved surface. The curvature of this curved surface can be set with reference to the curvature of the lens surface of the wireless probe 5, preferably with a curvature value smaller than that of the lens surface of the wireless probe 5. This design ensures that the cleaning head 7 can completely wipe the lens surface of the wireless probe 5 while reducing the pressure exerted by the cleaning head 7 on the lens surface of the wireless probe 5.

[0030] A fixed cylinder 21 is fixedly connected to the upper end face of the base 1. A lifting rod 22 is longitudinally slidably arranged inside the fixed cylinder 21. The L-shaped frame 2 is located on the upper end face of the lifting rod 22. A threaded sleeve 23 is rotatably provided on the fixed cylinder 21. The threaded sleeve 23 is sleeved on the lifting rod 22 and engages with it for lifting. The inner wall of the threaded sleeve 23 is provided with an internal thread, and the outer side of the lifting rod 22 is provided with an external thread that meshes with the internal thread for transmission. The rotation of the threaded sleeve 23 drives the lifting rod 22 to move up and down, completing the lifting of the L-shaped frame 2, thereby realizing the height adjustment of the wireless probe 5, which makes the use of this device more convenient.

[0031] The aforementioned threaded sleeve 23 is fixedly fitted with a worm gear 24, and a worm 25, which meshes with the worm gear 24, is rotatably mounted on the outer side of the fixed cylinder 21. A connecting plate is provided on the circumferential side of the fixed cylinder 21, and a drive motor 29 is mounted on the connecting plate. The output shaft of the drive motor 29 is connected to the worm 25. When the device needs to be raised or lowered, the drive motor 29 operates, and its output shaft drives the worm 25 to rotate. The worm 25, through the worm gear 24, drives the threaded sleeve 23 to rotate. The rotation of the threaded sleeve 23 allows the lifting rod 22 to rise or fall within the fixed cylinder 21, thereby adjusting the height of the wireless probe 5. In this design, the meshing of the worm gear 24 and the worm 25 constitutes a worm gear mechanism. Because the worm gear mechanism has strong load-bearing capacity, long service life, stable operation, and low noise, its use can reduce noise during the lifting process of the device, enabling it to operate relatively smoothly and for a long time.

[0032] A pair of guide blocks 26 are fixedly provided on the circumferential side of the lifting rod 22 near the bottom of the fixed cylinder 21. A pair of guide grooves 27 are opened opposite each other on the circumferential side of the fixed cylinder 21, and the pair of guide blocks 26 are slidably disposed in the pair of guide grooves 27. By moving the guide blocks 26 along the guide grooves 27, the lifting rod 22 can be guided.

[0033] In summary, this application provides an observation auxiliary device. An L-shaped frame 2 is set on a base 1, and a wireless probe 5 and a cleaning head 7 that abuts against the wireless probe 5 are set on the L-shaped frame 2. The cleaning head 7 is composed of a heating plate 8, a heat-resistant elastic element 9, and an absorbent cloth 10 to dry and wipe the water stains on the wireless probe 5. This solves to a certain extent the problem of unclear vision of the wireless probe 5 caused by rain and snow, enabling the device to conduct observations in inclement weather such as rain and snow.
