Description

Technical Field

[0001] This utility model relates to the field of height sensor technology, and in particular to a retaining and limiting device for the rotation of a height sensor. Background Technology

[0002] In the fields of aviation, meteorology and industrial measurement, altitude sensors often need to acquire data in multiple directions through rotational scanning. Their rotation mechanism usually relies on motor drive in conjunction with simple mechanical stops or electronic encoders for position control.

[0003] Traditional devices operate at a fixed height, making it difficult to flexibly adjust the vertical position of the sensor according to different terrains or the height of the target being measured, thus limiting its application in complex scenarios. Therefore, this invention proposes a retaining and limiting device for rotating height sensors to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a retaining and limiting device for the rotation of a height sensor.

[0005] To achieve the above objectives, this utility model provides a retaining and limiting device for rotating a height sensor, comprising two vertical plates. Each vertical plate has multiple longitudinally arranged positioning screw holes on its inner side. Two horizontal plates are longitudinally arranged between the two vertical plates, and a connecting plate is arranged between the two horizontal plates. Positioning blocks are fixedly arranged at the four bottom corners of each horizontal plate, and positioning screws are threaded onto the inner side of each positioning block. The positioning blocks are fixedly connected to the connecting plate via the positioning screws. A rotating motor is fixedly arranged at the top of the lower horizontal plate and is electrically connected to a controller. A support rod is fixedly arranged at the output end of the rotating motor. The top of the support rod passes through the upper horizontal plate and is fixedly connected to a mounting block. The top of the mounting block has a mounting groove for mounting the height sensor.

[0006] Furthermore, a base plate is provided below the horizontal plate, and sleeves are rotatably provided on both sides of the top of the base plate. A threaded rod is threaded into the sleeve, and a vertical rod is fixedly provided at the top of the threaded rod. The upper end of the vertical rod is fixedly connected to the adjacent vertical plate.

[0007] Furthermore, a telescopic rod is fixedly installed at the bottom of the sleeve, and the top end of the telescopic rod is fixedly connected to the threaded rod.

[0008] Furthermore, a motor slot is provided at the top center of the base plate, and a forward and reverse motor is fixedly installed in the motor slot. A support block is fixedly installed at the output end of the forward and reverse motor, and a first gear is fixedly installed on the top of the support block. Several second gears are arranged laterally on both sides of the first gear, and adjacent gears are meshed with each other. The second gears on both sides are fixedly sleeved on the sleeve, and the second gears are rotatably installed on the base plate through a rotating rod.

[0009] Furthermore, an L-shaped plate is provided on the inner wall of the vertical rod, one side of the L-shaped plate is fixedly connected to the vertical plate, and the other side of the L-shaped plate is fixedly connected to the vertical rod by a positioning screw.

[0010] Furthermore, both the positioning screw and the positioning rod are made of stainless steel, and an electromagnetic block is fixedly installed at the bottom of the mounting groove. The electromagnetic block is magnetically fixed to the bottom of the height sensor.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a forward and reverse motor-driven gear set on the base plate to rotate the sleeve, causing the threaded rod to rise and fall inside the sleeve, thereby realizing the vertical height adjustment of the entire sensor mounting platform. This solves the problem of fixed working height in traditional devices and can flexibly adjust the sensor position according to different terrains or the height of the target being measured, significantly improving adaptability in complex scenarios.

[0013] 2. The sleeves on both sides of this utility model rotate synchronously through a gear set, ensuring that the lifting and lowering process of the threaded rod and the vertical rod is smooth and synchronous, avoiding tilting or shaking of the sensor when adjusting the height, and ensuring the accuracy of the measurement.

[0014] 3. This utility model uses a rotating motor to drive the support rod to rotate, which in turn drives the mounting block and sensor to rotate synchronously, enabling multi-directional data acquisition. The motor is precisely controlled by an external controller, which can achieve positioning at any angle and continuous rotation to meet different measurement needs. The frame structure composed of horizontal and vertical plates provides stable support for the rotation system. The mounting groove at the top of the mounting block, together with the electromagnetic block at the bottom, can firmly fix the height sensor. Attached Figure Description

[0024] Please see Figure 1-4A retaining and limiting device for rotating a height sensor includes two vertical plates 2. Each vertical plate 2 has multiple positioning screw holes longitudinally arranged on its inner side. Two horizontal plates 1 are longitudinally arranged between the two vertical plates 2. A connecting plate 2 is arranged between the two horizontal plates 1. Positioning blocks 6 are fixedly arranged at the four corners of the bottom of the horizontal plates 1. Positioning screws 7 are threaded on the inner side of the positioning blocks 6. The positioning blocks 6 are fixedly connected to the connecting plate 2 through the positioning screws 7. A rotating motor 11 is fixedly arranged at the top of the lower horizontal plate 1 and is electrically connected to a controller. A support rod 10 is fixedly arranged at the output end of the rotating motor 11. The top of the support rod 10 passes through the upper horizontal plate 1 and is fixedly connected to a mounting block 4. The top of the mounting block 4 is provided with a mounting groove for mounting the height sensor. After receiving a command from the controller, the rotating motor 11 drives the support rod 10 to rotate around its axis. The support rod 10 is rigidly connected to the mounting block 4 to form a torque transmission chain. The horizontal plate 1 serves as a supporting frame, the mounting slot of the mounting block 4 forms a mechanical fit with the sensor, and the electromagnetic block 20 provides an adsorption force, so that the sensor rotates synchronously with the support rod 10 to achieve 360° continuous scanning or multi-angle positioning.

[0025] As an improvement to the above technical solution, a base plate 5 is provided below the horizontal plate 1. Sleeves 19 are rotatably mounted on both sides of the top of the base plate 5. A threaded rod 18 is threaded into the sleeve 19, and a vertical rod 3 is fixedly mounted at the top of the threaded rod 18. The upper end of the vertical rod 3 is fixedly connected to the adjacent vertical plate 2. A telescopic rod is fixedly mounted at the bottom of the sleeve 19, and its top end is fixedly connected to the threaded rod 18. A motor slot 16 is provided at the center of the top of the base plate 5, and a forward / reverse motor 17 is fixedly mounted within the motor slot 16. A support block 15 is fixedly installed at the output end, and a first gear 13 is fixedly installed on the top of the support block 15. Several second gears 12 are arranged laterally on both sides of the first gear 13, and adjacent gears are meshed together. The second gears 12 on both sides are fixedly sleeved on the sleeve 19. The second gears 12 are rotatably mounted on the base plate 5 through the rotating rod 14. The forward and reverse motors 17 drive the first gear 13 to rotate, and the power is synchronously transmitted to the second gears 12 on both sides through gear meshing. The second gears 12 drive the sleeve 19 to rotate around the rotating rod 14. Since the sleeve 19 and the threaded rod 18 form a screw and nut pair, and the telescopic rod restricts the circumferential rotational freedom of the threaded rod 18, the rotational motion of the sleeve 19 is converted into the linear lifting motion of the threaded rod 18. The threaded rods 18 on both sides synchronously support the vertical plate 2 through the vertical rod 3, realizing the height adjustment of the entire rotating platform.

[0026] As an improvement to the above technical solution, an L-shaped plate 9 is provided on the inner wall of the vertical rod 3. One side of the L-shaped plate 9 is fixedly connected to the vertical plate 2, and the other side of the L-shaped plate 9 is fixedly connected to the vertical rod 3 by a positioning screw 8. The positioning screw 8 and the positioning screw rod 7 are both made of stainless steel. An electromagnetic block 20 is fixedly provided at the bottom of the mounting groove. The electromagnetic block 20 is magnetically fixed to the bottom of the height sensor.

[0027] As an improvement to the above technical solution, the L-shaped plate 9 rigidly connects the vertical rod 3 and the vertical plate 2 through the positioning screw 8 to form a stable triangular structure. The positioning screw 8 and positioning rod 7 made of stainless steel have high strength and corrosion resistance. The electromagnetic block 20 uses electromagnetic force to attract the metal parts at the bottom of the sensor to achieve quick clamping and release.

[0028] The working principle and usage of this utility model:

[0029] In use, the rotational power is provided by the rotating motor 11, which is electrically controlled by an external controller. The output shaft of the rotating motor 11 drives the support rod 10 to rotate. The top of the support rod 10 passes through the upper horizontal plate 1 and is fixedly connected to the mounting block 4. The height sensor is fixed through the mounting groove on the top of the mounting block 4. The electromagnetic block 20 at the bottom of the groove can assist in fixing. When the support rod 10 rotates, it drives the mounting block 4 and the sensor to rotate synchronously, thereby realizing multi-directional data acquisition. The output shaft of the forward and reverse motor 17 drives the support block 15 and the first gear 13 on the top to rotate. The first gear 13 drives the second gears 12 on both sides to rotate synchronously through meshing. The outermost second gear 12 is fixedly sleeved on the sleeve 19, thereby driving the sleeve 19 to rotate on the base plate 5. The sleeve 19 has a threaded rod 18 inserted into its internal thread. When the sleeve 19 rotates, due to the limitation that the telescopic rod is fixed to the bottom of the sleeve 19 and the top end is connected to the threaded rod 18, the threaded rod 18 cannot rotate with the sleeve 19, but can only move up and down along the axial direction of the sleeve 19. The top end of the threaded rod 18 is fixedly connected to the vertical rod 3. Therefore, the lifting and lowering of the threaded rod 18 will drive the vertical rod 3 to lift and lower synchronously. The upper end of the vertical rod 3 is fixedly connected to the vertical plate 2, and the vertical plate 2 supports the horizontal plate 1 and the entire rotation drive system. Therefore, the lifting and lowering of the vertical rod 3 ultimately achieves the vertical height adjustment of the entire sensor. The two vertical plates 2 serve as the main vertical support structure, and the two horizontal plates 1 are fixed between the two vertical plates 2 by the positioning block 6 and the positioning screw 7, forming a stable horizontal frame. The multiple longitudinal positioning screw holes on the inner side of the vertical plate 2 allow adjustment of the relative position of the horizontal plate 1. One side of the L-shaped plate 9 is fixed to the vertical plate 2, and the other side is fixed to the vertical rod 3 by the positioning screw 8, which further strengthens the connection rigidity between the vertical rod 3 and the vertical plate 2. The positioning screw 7 and the positioning screw 8 are both made of stainless steel to ensure connection strength and durability. During the height adjustment process, the telescopic rod in the sleeve 19 not only prevents the rotation of the threaded rod 18, but also plays a guiding and limiting role, ensuring a smooth lifting and lowering process.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
