Description

Technical Field

[0001] This invention relates to the field of all-sky imager technology, and more specifically, to an all-sky imager for a low-maintenance weather station. Background Technology

[0002] With the development of natural science, cloud observation has been increasingly valued. In the early days, cloud observation required professionals to observe with the naked eye and manually record the results. The accuracy of the results varied greatly depending on the observer's experience and skill level. In order to reduce labor costs, improve observation accuracy, and achieve unattended, all-weather automatic observation of the sky, all-sky imagers have gradually replaced manual observation.

[0003] According to existing technology, all-sky imagers are mostly installed at high altitudes, which means that the installation work requires complex scaffolding or specialized hoisting equipment. At the same time, the fastening process requires precise docking and tedious debugging of multiple components. Since the overall operation is time-consuming and labor-intensive, the disassembly and reassembly of the equipment in the subsequent maintenance process must repeat the above complex process, which increases the maintenance difficulty and extends the maintenance time. This results in cumbersome maintenance work and increased maintenance costs. Summary of the Invention

A bearing seat is fixedly connected to the inner surface of the support rod, and the bearing seat is sleeved on the shaft. The external part of the sleeve rotates with the shaft to support and position the middle part of the shaft. A slider is fixedly connected to the side wall of the sleeve. A vertical groove adapted to the slider is opened on the inner wall of the support rod. The slider is embedded in the groove and slides with the groove to limit the sleeve from rotating synchronously with the lead screw. A slider is fixedly connected to the side wall of the sleeve. A groove adapted to the slider is opened on the inner wall of the support rod. The surface of the slider and the inner surface of the groove are slidably connected. A transmission gear is rotatably connected to the side wall of the sleeve. A rack meshing with the transmission gear is fixedly connected to the inner surface of the support rod.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. In the all-sky imager of this low-maintenance weather station, a servo motor drives a lead screw and a lead sleeve transmission assembly to move the moving sleeve vertically along the support rod, thereby realizing the raising and lowering of the all-sky imager body. Compared with traditional imagers that are fixedly installed at high places, this solution can lower the imager to a safe height through remote control or ground operation, avoiding safety hazards such as falling from height and electric shock, while reducing the manpower cost of maintenance.

This solves the problems of cumbersome disassembly and assembly of traditional bolt fixing methods and the inconvenience of carrying tools in outdoor environments, and improves maintenance efficiency.

[0024] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0025] Because the overall operation is time-consuming and labor-intensive, the disassembly and reassembly of the equipment need to repeat the above complex process during subsequent maintenance, which increases the difficulty of maintenance and extends the maintenance time. This results in cumbersome maintenance operations and increased maintenance costs.

[0026] Therefore, in view of the aforementioned problems, the present invention discloses an all-sky imager for a low-maintenance weather station, with reference to... Figure 1 As shown, the system includes a support rod 1, which adopts a single-rod vertical design. Compared with a multi-support distributed structure, this significantly reduces the amount of ground foundation construction work. At the same time, the single-rod structure has stronger wind resistance. A movable sleeve 2 that can move vertically along the surface of the support rod 1 is fitted on it. The movable sleeve 2 allows the imager body to be moved to a safe height for maintenance without the need for staff to climb. A support block 4 is fixedly installed on the movable sleeve 2. The support block 4 serves as a transition structure connecting the movable sleeve 2 and the straight arm 7. Compared with the hinge connection method, the structure has higher strength. The straight arm 7 is fixedly connected to the end of the support block 4. One end of the straight arm 7 is fitted with a plug sleeve 11 that is fixedly connected to the all-sky imager body 8. The fitting of the plug sleeve 11 and the straight arm 7 provides a basis for quick assembly of the imager body. Compared with the bolt flange connection, the fitting method is faster in positioning.

[0027] refer to Figure 5As shown, the inner wall of the sleeve 11 has two slots 12, and the straight arm 7 has two sliding heads 13. The two heads 13 are respectively inserted into the two slots 12 of the sleeve 11. The snap-fit ​​fixing structure of the slots 12 and the heads 13 replaces the traditional bolt locking method. The imaging device body can be quickly fixed and disassembled without the need for tools such as wrenches, thus saving installation and disassembly time. At the same time, the symmetrical design of the double slots 12 and double heads 13 makes the force on the card more even, which can effectively resist the loosening of the connection caused by outdoor vibration and bumps. A servo motor 10 is fixedly installed at the bottom of the support rod 1. It can provide stable power for the lifting of the moving sleeve 2 and the extension and retraction of the heads 13 through precise speed and direction control.

[0028] refer to Figure 2-5 As shown, the output end of the servo motor 10 is connected to a transmission component, which is connected to the movable sleeve 2 and the two clamps 13 respectively. The transmission component is used to drive the movable sleeve 2 to move and drive the clamps 13 to move. The single servo motor 10 serves as the core power source, realizing the lifting and lowering of the movable sleeve 2 and the extension and retraction of the clamps 13. This reduces the number of motors, controllers and other components, simplifies the overall structure of the equipment, and reduces the production cost and the probability of failure.

[0029] The transmission assembly includes a shaft 15 fixedly connected to the output end of the servo motor 10, a bearing seat 16 fixedly connected to the inner surface of the support rod 1, the shaft 15 being inserted into the inner surface of the bearing seat 16, the bearing seat 16 providing stable rotational support for the shaft 15, limiting the radial offset of the shaft 15 during rotation, and ensuring the coaxiality of the shaft 15 transmission. A lead screw 17 is fixedly connected to the top end of the shaft 15, the top end of the lead screw 17 being rotatably connected to the inner surface of the support rod 1, and a threaded sleeve 18 being threaded onto the surface of the lead screw 17. The arrangement of the lead screw 17 and the threaded sleeve 18 has the characteristics of high transmission accuracy and high mechanical efficiency, and can accurately convert the rotational motion of the servo motor 10 into the vertical linear motion of the threaded sleeve 18.

[0030] refer to Figure 6-7As shown, a connecting block 39 is fixedly connected to the side wall of the threaded sleeve 18. A long strip-shaped opening is provided on the side wall of the support rod 1 for the connecting block 39 to slide vertically. One end of the connecting block 39 extends through the long strip-shaped opening to the outside of the support rod 1. The surface of the connecting block 39 is fixedly connected to the inner wall of the movable sleeve 2. The connecting block 39 serves as a connector between the threaded sleeve 18 and the movable sleeve 2, realizing the effective transmission of the internal power of the support rod 1 to the external movable sleeve 2. The long strip-shaped opening provides precise vertical movement guidance for the connecting block 39 and restricts the circumferential rotation of the connecting block 39. A slider 19 is fixedly connected to the side wall of the threaded sleeve 18. A groove 20 adapted to the slider 19 is provided on the inner wall of the support rod 1. The surface of the slider 19 and the inner surface of the groove 20 are slidably connected. The sliding cooperation between the slider 19 and the groove 20 forms a secondary guide structure for the vertical movement of the threaded sleeve 18. This structure cooperates with the threaded guidance of the threaded sleeve 18 by the lead screw 17, further restricting the circumferential rotation and radial offset of the threaded sleeve 18, making the lifting and lowering movement of the threaded sleeve 18 more stable and smooth.

[0031] refer to Figure 4-7 As shown, a transmission gear 21 is rotatably connected to the side wall of the thread sleeve 18, and a rack 40 that meshes with the transmission gear 21 is fixedly connected to the inner surface of the support rod 1. The meshing of the transmission gear 21 and the rack 40 can convert the vertical linear motion of the thread sleeve 18 into the rotational motion of the transmission gear 21, providing power for the subsequent extension and retraction of the chuck 13, realizing the secondary conversion of lifting power into disassembly and assembly power. A rotating shaft 22 is fixedly connected to the surface of the transmission gear 21, and an active bevel gear 24 is fixedly connected to the surface of the rotating shaft 22. The active bevel gear 24 can realize the direction of power transmission, thereby adapting to the power direction conversion requirement from the vertical movement of the thread sleeve 18 to the lateral extension and retraction of the chuck 13, and also simplifying the transmission link.

[0032] A bearing 23 is fitted on the surface of the rotating shaft 22. The outer ring of the bearing 23 is fixedly connected to the movable sleeve 2. The bearing 23 can convert the sliding friction of the rotating shaft 22 into rolling friction, which greatly reduces the friction and energy loss in the transmission process. At the same time, it limits the radial displacement of the rotating shaft 22. The surface of the driving bevel gear 24 is meshed with the driven bevel gear 25. The driven bevel gear 25 smoothly transmits the rotational power to the cam 26, ensuring that the extension and retraction of the chuck 13 is uniform and smooth, and avoiding poor engagement or disengagement.

[0033] A cam 26 is fixedly connected to the surface of the driven bevel gear 25. The cam 26 converts the rotational motion into the reciprocating linear motion of the moving bar 28. A rotating rod 27 is fixedly connected to the side wall of the cam 26. The side wall of the rotating rod 27 is rotatably connected to the inner surface of the moving sleeve 2. The rotating rod 27 provides a stable rotational support point for the cam 26, restricts the axial movement of the cam 26, and ensures that the contact position between the cam 26 and the moving bar 28 is accurate. The side wall of the cam 26 is provided with a moving bar 28. Two positioning rods 30 are slidably connected to the inner wall of the moving bar 28. The positioning rods 30 provide accurate guidance for the reciprocating motion of the moving bar 28, restricts the lateral offset of the moving bar 28, and ensures that the moving bar 28 always moves in a straight line. This ensures that the extension and retraction trajectory of the push-pull rod 34 driving the chuck 13 is accurate and avoids misalignment between the chuck 13 and the slot 12.

[0034] A protective box 14 is fixedly connected to the surface of the movable sleeve 2. The protective box 14 completely encloses the core transmission components such as the cam 26, the moving strip 28, and the spring 32, effectively blocking the erosion of outdoor environmental factors such as rain, dust, and ultraviolet rays. A fixing strip 31 is fixedly connected to the inner surface of the protective box 14. The side wall of the fixing strip 31 is fixedly connected to the side wall of the positioning rod 30. The fixing strip 31 provides a stable installation base for the positioning rod 30, ensuring that the positioning rod 30 does not loosen in outdoor vibration environments. A spring 32 is fitted on the surface of the positioning rod 30. The two ends of the spring 32 are fixedly connected to the surfaces of the fixing strip 31 and the moving strip 28, respectively. The spring 32 provides the reset power for the moving strip 28 through preload, ensuring that the moving strip 28 can quickly return to its initial position after the cam 26 rotates, realizing the automatic reset of the chuck 13.

[0035] refer to Figure 4 and Figure 5 As shown, a slide rod 29 is fixedly connected to the side wall of the moving bar 28. Three sliding sleeves 33 are inserted into the inner surface of the straight arm 7. The slide rod 29 is inserted into the inner surface of the three sliding sleeves 33. The three sliding sleeves 33 are evenly distributed along the axis of the slide rod 29 to form a multi-point guide structure. Two push-pull rods 34 are rotatably connected to the side wall of the slide rod 29. The end of the push-pull rod 34 away from the slide rod 29 is fixedly connected to the clamp head 13. The push-pull rod 34 adopts a combination of rotatable connection and fixed connection, which can flexibly adapt to the trajectory conversion from linear motion of the slide rod 29 to linear motion of the clamp head 13.

[0036] A limiting rod 38 is fixedly connected to the inner surface of the straight arm 7. Two limiting sleeves 35 are slidably connected to the surface of the limiting rod 38. The side wall of the limiting sleeve 35 is fixedly connected to the clamp head 13. The limiting rod 38 and the limiting sleeve 35 constitute a dedicated guide structure for the extension and retraction of the clamp head 13. This structure can accurately limit the movement trajectory and stroke of the clamp head 13, avoid structural damage caused by excessive extension and retraction of the clamp head 13, and at the same time share the radial force borne by the clamp head 13, reducing the friction and wear between the clamp head 13 and the inner wall of the straight arm 7.

[0037] refer to Figure 1 and Figure 5 As shown, a corrugated sleeve 9 is fixed to the surface of the movable sleeve 2 and the bottom end of the support rod 1. The corrugated sleeve 9 can expand and contract synchronously with the lifting and lowering of the movable sleeve 2, which can block the long strip opening on the side wall of the support rod 1 to form a sealed protective barrier, effectively preventing outdoor rainwater, sand, insects and other impurities from entering the interior of the support rod 1. A first magnet 37 is provided on the inner surface of the straight arm 7, and a second magnet 36 is inserted into the inner wall of the insert sleeve 11. The first magnet 37 and the second magnet 36 magnetically attract each other. The magnetic attraction structure can achieve quick pre-positioning of the straight arm 7 and the insert sleeve 11 without additional tools. When installing the imaging device body, it can quickly align the relative positions of the card head 13 and the card slot 12, avoid the failure of the card engagement caused by misalignment during installation, and improve the assembly efficiency.

[0038] refer to Figure 8 As shown, a photovoltaic panel 3 is fixedly installed on the surface of the movable sleeve 2. The photovoltaic panel 3 can convert solar energy into electrical energy to provide continuous power to the servo motor 10, the all-sky imager body 8, the rain gauge 6 and other equipment. An inclined arm 5 is fixedly connected to the side wall of the support block 4. The rain gauge 6 is fixedly connected to the surface of the inclined arm 5. The inclined arm 5 supports the rain gauge 6 so that the rain gauge 6 is kept in an airborne position, without the need to build a separate independent bracket for the rain gauge 6.

[0039] The working principle of this invention is as follows: The all-sky imager body 8 is fitted onto the end of the straight arm 7 through the sleeve 11. The first magnet 37 inside the straight arm 7 and the second magnet 36 inside the sleeve 11 are quickly attracted by magnetic attraction, automatically aligning with the slot 12 and the head 13, thus completing the pre-positioning of the imager body. At the same time, the rain gauge 6 is fixed to the support block 4 through the inclined arm 5. The servo motor 10 at the bottom of the support rod 1 is started. The motor output drives the shaft 15, which is radially offset and rotated through the bearing seat 16. The lead screw 17 at the top of the shaft 15 rotates synchronously. Since the lead sleeve 18 restricts circumferential rotation through the sliding groove 20 on the inner wall of the support rod 1 via the slider 19, the rotational motion of the lead screw 17 is precisely converted into the upward vertical linear motion of the lead sleeve 18.

[0040] The wire sleeve 18 passes through the long strip opening on the side wall of the support rod 1 via the connecting block 39, and drives the external movable sleeve 2 to slide upward along the support rod 1. The movable sleeve 2 simultaneously drives the straight arm 7, the imaging device body 8, the support block 4, the inclined arm 5, the rain gauge 6, and the photovoltaic panel 3 to rise as a whole. During this process, the corrugated sleeve 9 extends synchronously with the moving sleeve 2 as it rises, blocking the long strip opening and preventing rainwater, sand and dust and other impurities from entering the interior of the support rod 1.

[0041] When the threaded sleeve 18 rises, the transmission gear 21 reduces friction and limits radial offset through the bearing 23 via the rotating shaft 22, driving the driving bevel gear 24 to rotate. The driving bevel gear 24 meshes with and drives the driven bevel gear 25 to turn, thereby driving the cam 26 to rotate.

[0042] When the cam 26 rotates, it presses the moving bar 28, causing the moving bar 28 to move along the positioning rod 30 on the fixed bar towards the straight arm 7, while the spring 32 is compressed. The moving bar 28 pushes the two push-pull rods 34 through the slide rod 29 and the three sliding sleeves 33. The push-pull rods 34 drive the locking head 13 to extend outward along the limiting rod 38 towards the straight arm 7, while being guided by the limiting sleeve 35, and finally inserting it into the slot 12 of the insert sleeve 11, realizing the automatic locking and fixing of the imager body 8. When the moving sleeve 2 drives the imager body 8, photovoltaic panel 3, and rain gauge 6 to rise to the preset working height, and the locking head 13 is fully locked into the slot 12, the servo motor 10 stops working. At this time, the photovoltaic panel 3 reaches the designated height with the moving sleeve 2 and begins to receive solar energy, storing electrical energy for the subsequent operation of the equipment.

[0043] When maintenance of the imager body 8, rain gauge 6, or repair of photovoltaic panel 3 is required, the staff controls the servo motor 10 to reverse on the ground. The shaft 15 drives the lead screw 17 to rotate in the opposite direction. The lead sleeve 18 moves vertically downward along the slide groove 20. Through the connecting block 39, the moving sleeve 2 and all integrated components descend synchronously. When the lead sleeve 18 descends, the transmission gear 21 moves downward with the lead sleeve 18 and meshes with the rack 40 to rotate in the opposite direction. Through the rotating shaft 22, the driving bevel gear 24, and the driven bevel gear 25, the cam 26 rotates in the opposite direction. The squeezing force of the cam 26 on the moving bar 28 disappears, the spring 32 releases its stored energy, and pushes the moving bar 28 to reset along the positioning rod 30. The slide rod 29 drives the push-pull rod 34 to pull the clasp 13 back into the straight arm 7. The clasp 13 separates from the clasp 12, and the imager body 8 is unlocked.

[0044] The mobile sleeve 2 continues to descend to a safe height accessible to the staff, and the servo motor 10 stops working. The staff can directly pull out the imager body 8 along the straight arm 7, which can be disassembled without the aid of tools. At the same time, the rain gauge 6, photovoltaic panel 3 or parts can be easily inspected or replaced. The whole process does not require climbing, and the operation is safe and efficient.
