Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a wireless dual-axis laser speed sensor. Background Technology

[0002] The wireless dual-axis laser velocity sensor is a non-contact measurement device based on the laser Doppler effect, capable of acquiring the real-time velocity of an object in two orthogonal directions. It emits two laser beams and receives the reflected light, calculating the object's linear or angular velocity using frequency shift. Supporting wireless data transmission, it enables dynamic monitoring and remote control, and is widely used in industrial automation, traffic monitoring, logistics sorting, scientific research experiments, and other scenarios, meeting the need for accurate measurement of multi-dimensional velocity parameters of moving objects.

[0003] Existing wireless dual-axis laser velocity sensors often employ fixed installation methods, which are not suitable for adapting to the needs of different measurement scenarios. For example, when measuring objects at different heights or in complex terrain, the laser beam may not be accurately aligned with the target, affecting measurement accuracy. At the same time, existing sensors often rely on plane mirrors or lenses to receive the emitted laser, but they cannot effectively focus the diverging reflected light, resulting in a large amount of laser energy loss and insufficient signal strength. This is especially true for targets at long distances and with low reflectivity, leading to reduced detection accuracy. Therefore, this application proposes a wireless dual-axis laser velocity sensor. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wireless dual-axis laser speed sensor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A wireless dual-axis laser speed sensor includes a mounting base. Multiple lifting mechanisms are symmetrically mounted on the top surface of the mounting base. A rotating ball is fixedly mounted at the top of each lifting mechanism. A protective sleeve is provided on the top surface of the mounting base. Multiple rotating sleeves are symmetrically mounted on the bottom surface of the protective sleeve, and each rotating sleeve is rotatably connected to a corresponding rotating ball. A sensor body is slidably connected inside the protective sleeve. Arc-shaped covers are fixedly mounted on both outer sides of the protective sleeve. Each arc-shaped cover has a metal plating on its inner wall. A filter plate is mounted on the outer side of each arc-shaped cover. A cover plate is rotatably connected to the outer side of the protective sleeve. A limiting mechanism is provided on the cover plate, and the limiting mechanism restricts the position of the cover plate.

[0006] Preferably, each of the lifting mechanisms includes a telescopic sleeve, and each telescopic sleeve is fixedly installed on the top surface of the mounting base. A sliding plate is slidably connected inside each telescopic sleeve. A threaded rod is rotatably connected to the bottom wall of each telescopic sleeve, and each threaded rod is threadedly connected to the corresponding sliding plate. An extension rod is fixedly installed on the top surface of each sliding plate, and each rotating ball is fixedly installed on the top end of the corresponding extension rod.

[0007] Preferably, the limiting mechanism includes a U-shaped rod, which is slidably connected to the outside of the cover plate. Both ends of the U-shaped rod are equipped with springs along with the outside of the cover plate. Both ends of the U-shaped rod penetrate the cover plate and are inserted into the protective sleeve.

[0008] Preferably, each of the threaded rods is equipped with a knob at its bottom end, and each of the protective sleeves has multiple heat dissipation grooves on its outer side.

[0009] Preferably, each of the telescopic sleeves has multiple symmetrically formed grooves on its inner wall, and each slide plate is slidably connected to the groove corresponding to its position.

[0010] Preferably, the top surface of the mounting base is symmetrically provided with multiple mounting holes, and the metal coating is an aluminum coating.

[0011] This utility model has the following beneficial effects: 1. This utility model uses a lifting mechanism, a rotating ball, a rotating sleeve, a protective sleeve, a limiting mechanism, and a sensor body to enable the sensor body to slide into the protective sleeve for protection. Furthermore, by controlling the lifting of multiple lifting mechanisms in conjunction with the rotating ball and rotating sleeve, the protective sleeve can be made to slide upward as a whole, or one side of the protective sleeve can be raised while the other side remains in the same position, thereby changing the tilt angle of the protective sleeve to facilitate the measurement of objects at different heights or complex terrain.

[0012] 2. This utility model uses devices such as an arc-shaped cover, a metal coating, and a filter plate to enable the reflected laser beam to be focused through the arc-shaped cover, thereby improving the signal receiving efficiency. Furthermore, the metal coating ensures that as much laser energy as possible is emitted and focused onto the receiver of the sensor body, which can further enhance the signal receiving efficiency. The filter plate can also enhance the anti-interference capability of the arc-shaped cover. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] This utility model provides a technical solution: such as Figure 1-4 As shown, the wireless dual-axis laser speed sensor includes a mounting base 1. Multiple lifting mechanisms are symmetrically mounted on the top surface of the mounting base 1. A rotating ball 5 is fixedly mounted at the top of each lifting mechanism. A protective sleeve 7 is provided on the top surface of the mounting base 1. Multiple rotating sleeves 6 are symmetrically mounted on the bottom surface of the protective sleeve 7, and each rotating sleeve 6 is rotatably connected to the rotating ball 5 in a corresponding position. A sensor body 12 is slidably connected inside the protective sleeve 7. Arc-shaped covers 14 are fixedly mounted on both outer sides of the protective sleeve 7. Each arc-shaped cover 14 has a metal plating on its inner wall, and a filter plate 15 is mounted on the outer side of each arc-shaped cover 14. A cover plate 13 is rotatably connected to the outer side of the protective sleeve 7. A limiting mechanism is provided on the cover plate 13, and the limiting mechanism restricts the position of the cover plate 13.

[0017] It should be noted that each rotating ball 5 can rotate freely within the rotating sleeve 6, and at least four sets of multiple lifting mechanisms are set, and the multiple lifting mechanisms are symmetrically arranged. By adjusting the lifting mechanisms at different positions, the rotating balls 5 at different positions can be raised and lowered, thereby adjusting the height and tilt angle of the protective sleeve 7. Furthermore, the laser reflected by the arc-shaped cover 14 is focused to improve the signal reception efficiency. The metal coating ensures that as much laser energy as possible is emitted and focused onto the receiver of the sensor body 12, and the filter plate 15 enhances the anti-interference capability, allowing only specific wavelengths of laser light to pass through.

[0018] Furthermore, each lifting mechanism includes a telescopic sleeve 3, and each telescopic sleeve 3 is fixedly installed on the top surface of the mounting base 1. Each telescopic sleeve 3 has a sliding plate 10 slidably connected inside it. Each telescopic sleeve 3 has a threaded rod 8 rotatably connected to its bottom wall, and each threaded rod 8 is threadedly connected to the corresponding sliding plate 10. Each sliding plate 10 has an extension rod 4 fixedly installed on its top surface, and each rotating ball 5 is fixedly installed on the top of the corresponding extension rod 4. It should be noted that the extension rod 4 is hollow inside, and the threaded rod 8 extends into the extension rod 4, and the thread has self-locking properties, thereby stabilizing the sliding plate 10 in this position.

[0019] Furthermore, the limiting mechanism includes a U-shaped rod 17, which is slidably connected to the outside of the cover plate 13. Both ends of the U-shaped rod 17 are equipped with springs 18 along with the outside of the cover plate 13. Both ends of the U-shaped rod 17 penetrate the cover plate 13 and are inserted into the protective sleeve 7. The springs 18 can securely lock the U-shaped rod 17 into the protective sleeve 7. Since the cover plate 13 is to be opened by rotation, the U-shaped rod 17 can limit the rotation of the cover plate 13, thereby ensuring that the cover plate 13 cannot be opened by itself.

[0020] Furthermore, each threaded rod 8 is equipped with a knob 9 at its bottom end, and each protective sleeve 7 has multiple heat dissipation slots 16 on its outer side to facilitate heat dissipation of the sensor body 12.

[0021] Furthermore, each telescopic sleeve 3 has multiple symmetrically opened grooves 11 on its inner wall, and each slide plate 10 is slidably connected to the corresponding groove 11. The groove 11 can limit the slide plate 10 so that it cannot rotate and can only slide linearly.

[0022] Furthermore, the top surface of the mounting base 1 is symmetrically provided with multiple mounting holes 2, the metal coating is an aluminum coating, and an anti-oxidation layer can be provided on the outside of the aluminum coating to reduce the oxidation of the aluminum coating.

[0023] This utility model provides a wireless dual-axis laser speed sensor. The specific working principle is as follows: When using it, the operator can first insert the external bolt into the mounting hole 2 and fix the mounting base 1 in the designated position. Then, the operator can manually pull out the U-shaped rod 17 to release the limitation on the cover plate 13, so that the cover plate 13 can be rotated to open the protective sleeve 7. Then, the operator inserts the sensor body 12 into the protective sleeve 7. Then, the transmitting end and receiving end on the sensor body 12 correspond to the transmitting end and the arc-shaped cover 14 installed on the outside of the protective sleeve 7, respectively. Then, the operator rotates the cover plate 13 to close the protective sleeve 7, and the U-shaped rod 17 is inserted into the protective sleeve 7 to complete the limitation on the cover plate 13. Next, when the operator needs to adjust the height or rotation angle of the protective sleeve 7, if the number of rotations of each knob 9 is adjusted to be consistent, the protective sleeve 7 can be slid upward as a whole to adjust the height of the protective sleeve 7. If the tilt angle of the protective sleeve 7 is to be adjusted, the number of rotations of multiple knobs 9 on one side can be adjusted to be consistent, which can drive the threaded rod 8 to rotate, thereby driving the slide plate 10 and extension rod 4 to slide outward, pushing the height of one side of the protective sleeve 7 to increase, and thus causing the protective sleeve 7 to tilt and rotate, which is convenient for measuring objects of different heights or complex terrain. Furthermore, when the sensor body 12 is in use, the reflected laser beam can be focused by the arc-shaped cover 14, thereby improving the signal receiving efficiency. The metal coating ensures that as much laser energy as possible is emitted and focused onto the receiver of the sensor body 12. At the same time, the filter plate 15 allows only specific wavelengths of laser light to pass through, which enhances the anti-interference capability.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
