Description

Technical Field

[0001] This utility model relates to the field of dynamic tracking turntable technology, and in particular to a dynamic tracking turntable with no blind spots. Background Technology

[0002] Outdoor unmanned bird deterrent devices, outdoor high-precision dynamic tracking turntables, etc., are all dual-axis turntables. Figure 1 As shown, most existing dynamic tracking turntables generally include a turntable base 1, a fork arm 2, and a main unit 3. The azimuth axis at the top of the turntable base 1 can rotate the fork arm 2 360 degrees. The main unit 2, which uses a photoelectric tracking system, is rotatably connected to the symmetrically arranged side arms of the fork arm 2 via a horizontally set pitch axis to realize the pitch movement of the main unit 2.

[0003] However, since the turntable base 1 is generally fixed horizontally on the mounting frame, and the pitch angle of the main unit 2 is often ±90°, it is impossible to monitor the area below the mounting frame. Although some customized dynamic tracking turntables can expand the pitch angle range to ±180°, due to the limitations of the turntable base 1, the area directly below and around it remains a blind spot. When used for detecting mobile personnel or wild animals, if the target enters the blind spot area, it cannot be tracked throughout the entire process, resulting in the loss of the target.

[0004] To overcome the above problems, a dynamic tracking turntable with no blind spots is needed. Utility Model Content

[0005] The purpose of this invention is to provide a dynamic tracking turntable with no blind spots, reducing the obstruction effect of the turntable base and thus reducing monitoring blind spots.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model relates to a dynamic tracking turntable with no blind spots, comprising a turntable base, a fork arm, and a main unit, as well as a cantilever tilting shaft, a tilting shaft box, a tilting drive assembly, and an adapter seat. The cantilever tilting shaft is horizontally arranged, and its front end is fixedly connected to the outer side wall of the turntable base. The rear end of the cantilever tilting shaft is rotatably connected to the tilting shaft box, and the tilting drive assembly can drive the cantilever tilting shaft to reciprocate. The top plate of the adapter seat is fixedly connected to the bottom plate of the tilting shaft box, and the side plate of the adapter seat is mounted on a cantilever bracket for supporting the equipment.

[0008] The use of the aforementioned cantilever bracket minimizes obstruction caused by the bracket itself, maximizing the panoramic view. The method by which the cantilever tilting shaft drives the turntable body to rotate is an industry first, designed to reduce blind spots and increase the monitoring range.

[0009] Furthermore, it also includes a front bearing housing and a rear bearing housing, with the rear section of the cantilever tilting shaft mounted on the front and rear side walls of the tilting shaft box via the front and rear bearing housings.

[0010] Furthermore, a dustproof sealing ring is installed at the shaft hole of the front bearing housing.

[0011] The slewing support method with bearing seats installed on the outer wall can increase the distance between the two support points, thereby increasing the support stability of the cantilever tilting shaft.

[0012] Furthermore, the flipping drive assembly includes a worm gear, a worm, and a motor. The worm gear is coaxially and keyed to the cantilever flipping shaft and located inside the flipping shaft box. The worm is meshed and driven by the worm gear, and the worm is horizontally positioned and located directly below the worm gear. The motor end flange is connected to the outer wall of the flipping shaft box, and the output shaft of the motor is coaxially connected to the worm.

[0013] Furthermore, the motor is specifically a servo motor.

[0014] The use of a worm gear drive is also a thoughtful design by the applicant, which enables self-locking at any flip position and avoids slippage due to its own weight.

[0015] Furthermore, it also includes a corner plate and a reset sensor. The corner plate is coaxially mounted on the cantilever tilting shaft and located inside the tilting shaft box. A sensing block is provided at the outer edge of the corner plate. The reset sensor is installed on the inner side wall of the tilting shaft box and can sense the signal of the sensing block passing by and transmit it to the equipment's electrical control system.

[0016] Furthermore, the adapter is an L-shaped plate seat structure, with a rib plate between the top plate and the side upright plate of the adapter, and four mounting screws symmetrically arranged on both sides of the rib plate to connect to the flange plate of the cantilever bracket.

[0017] This utility model also discloses a working method for a dynamic tracking turntable with no blind spots, which uses the dynamic tracking turntable with no blind spots described in any of the above-mentioned methods to protect the horizontal support shaft of an outdoor turntable from rainwater.

[0018] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0019] This utility model relates to a dynamic tracking turntable with no blind spots. By adding a cantilevered tilting shaft and a tilting shaft box, the cantilevered tilting shaft connects to the turntable base, allowing the turntable base to rotate around the axis of the cantilevered tilting shaft. Therefore, when it is necessary to observe the field of view below the turntable base, simply tilt the turntable base downwards, allowing the host to bypass the turntable base and monitor the area below. The tilting drive assembly drives the cantilevered tilting shaft to rotate, thus tilting the turntable base. An adapter connects the cantilever support and the tilting shaft box, clearing the area directly below the turntable base for easier monitoring. This utility model of a dynamic tracking turntable with no blind spots reduces the obstruction caused by the turntable base, thereby reducing monitoring blind spots.

[0020] Furthermore, the rear section of the cantilever tilting shaft is supported by the front and rear bearing seats, reducing resistance during the tilting process. The bearing seats mounted on the front and rear side walls of the tilting shaft box, relative to the inner wall mounting method, increase the spacing, ensuring the cantilever tilting shaft meets bending strength requirements. The use of a worm gear reduction system achieves a large reduction ratio, resulting in greater torque, and provides good self-locking, preventing the cantilever tilting shaft from automatically tilting downwards due to the weight of the front turntable base components. The motor is a servo motor, controlled by the equipment's electrical control system, enabling control of the tilting angle. The addition of a corner plate and reset sensor records and senses the initial angle position of the corner plate, ensuring smooth initialization after power-on. The addition of set screws allows for convenient adjustment of the axial and angular rotation of the corner plate. The addition of the corner rib plate significantly increases the strength of the adapter, ensuring stable installation of the tilting shaft box. Attached Figure Description

[0026] The core of this invention is to provide a dynamic tracking turntable with no blind spots, reducing the obstruction effect of the turntable base and thus reducing monitoring blind spots.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Refer to the attached diagram. Figure 1 This is a schematic diagram of the front view structure of an outdoor turntable in the prior art; Figure 2 This is a schematic diagram of the main structure of the dynamic tracking turntable with no blind spots of this utility model; Figure 3 This is a partial cross-sectional view of the flip-up shaft box in this utility model.

[0030] In one specific implementation, such as Figures 1-3 As shown, the present invention's no-dead-angle dynamic tracking turntable is similar to existing dynamic tracking turntables in that it includes a turntable base 1, a fork arm 2, and a main unit 3. The fork arm 2 rotates on the turntable base 1, and the main unit 3 tilts on the fork arm 2. A key improvement of this no-dead-angle dynamic tracking turntable is the inclusion of a cantilever tilting shaft 4, a tilting shaft box 7, a tilting drive assembly, and an adapter 11. The cantilever tilting shaft 4 is horizontally positioned, with its front end fixedly connected to the outer wall of the turntable base 1. Preferably, the turntable base 1 is a square base, and the front end of the cantilever tilting shaft 4 is detachably connected to the side wall of the turntable base 1 via a flange and screws. The rear end of the cantilever tilting shaft 4 is rotatably connected within the tilting shaft box 7, and the tilting drive assembly can drive the cantilever tilting shaft 4 to reciprocate around its own axis. The top plate of the adapter 11 is fixedly connected to the bottom plate of the tilting shaft box 7, and the two are connected by screws. The side plates of the adapter 11 are mounted on a cantilever bracket for supporting the equipment.

[0031] Specifically, the cantilever support can be a cantilever tube, and the other end of the cantilever support is installed on the ground via a column.

[0032] By adding a cantilever tilting shaft 4 and a tilting shaft box 7, the cantilever tilting shaft 4 connects to the turntable base 1, allowing the turntable base 1 to rotate around the axis of the cantilever tilting shaft 4. Therefore, when it is necessary to observe the field of view below the turntable base 1, it is only necessary to tilt the turntable base 1 downwards, allowing the host 3 to bypass the turntable base 1 and monitor the area below. The tilting drive assembly drives the cantilever tilting shaft 4 to rotate, thus tilting the turntable base 1. An adapter 11 connects the cantilever support and the tilting shaft box 7, clearing the area directly below the turntable base 1 for easier monitoring. This invention provides a dynamic tracking turntable with no blind spots, reducing the influence of the turntable base 1 and thus reducing monitoring blind spots.

[0033] In one specific embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the dynamic tracking turntable with no dead angle of this utility model also includes a front bearing seat 5 and a rear bearing seat 6. The rear section of the cantilever tilting shaft 4 is mounted on the front and rear side walls of the tilting shaft box 7 through the front bearing seat 5 and the rear bearing seat 6.

[0034] Specifically, such as Figure 3 As shown, a dustproof seal ring is installed at the shaft hole of the front bearing housing 5, and the bearing mounting shaft section is also axially limited by a shaft elastic retaining ring and a shaft shoulder. Both the front bearing housing 5 and the rear bearing housing 6 are connected to the side wall of the flip-up shaft box 7 by screws at their outer edges.

[0035] Specifically, such as Figure 3 As shown, the top cover of the flip shaft box 7 is a detachable top cover, which is installed on the top opening of the flip shaft box 7 by screws, and a sealing gasket is provided between the two.

[0036] The rear section of the cantilever tilting shaft 4 is supported by the front bearing housing 5 and the rear bearing housing 6, which reduces the resistance during the tilting process. In addition, the bearing housings installed on the front and rear side walls of the tilting shaft box 7 are installed relative to the inner wall, which increases the spacing and ensures that the bending strength of the cantilever tilting shaft 4 meets the requirements.

[0037] In one specific embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the tilting drive assembly includes a worm gear 8, a worm 9, and a motor 1. The worm gear 8 is coaxially and keyed to the cantilever tilting shaft 4 and located inside the tilting shaft box 7. The worm 9 is meshed with the worm gear 8 for transmission, with a reduction ratio of 20. The worm 9 is horizontally positioned and located directly below the worm gear 8. The end flange of the motor 10 is connected to the outer wall of the tilting shaft box 7, and the output shaft of the motor 10 is coaxially connected to the worm 9. Both ends of the worm 9 are supported at the bottom of the inner cavity of the tilting shaft box 7 by bearings.

[0038] Specifically, motor 10 is a controllable motor, specifically a servo motor. The output revolutions of motor 10 can be controlled by a matching encoder.

[0039] By employing a worm gear reduction system, a larger reduction ratio can be achieved, resulting in greater torque. Furthermore, it offers excellent self-locking, preventing the cantilever tilting shaft 4 from automatically tilting downwards due to the weight of the front turntable base 1. The motor 10 is a servo motor, controlled by the equipment's electrical control system, and can control the tilting angle.

[0040] Obviously, the flipping drive assembly can also be driven by a gear and rack mechanism, with the motor 10 replaced by an electric push rod. The electric push rod pushes the rack located at the bottom of the inner cavity of the flipping shaft box 7. By controlling the push-out stroke of the electric push rod, the rotation angle of the cantilever flipping shaft 4 can be controlled.

[0041] In one specific embodiment of this utility model, such as Figure 3 As shown, the dynamic tracking turntable with no blind spots of this utility model also includes a corner disk 13 and a reset sensor 14. The corner disk 13 is coaxially mounted on the cantilever tilting shaft 4 and located inside the tilting shaft box 7. A sensing block 131 is provided at the outer edge of the corner disk 13. The reset sensor 14 is installed on the inner side wall of the tilting shaft box 7, and the reset sensor 14 can sense the signal when the sensing block 131 passes by and transmit it to the equipment's electronic control system.

[0042] Specifically, such as Figure 3 As shown, the sensing block 131 is a magnet fixed to the outer edge of the corner plate 13. The reset sensor 14 is triggered by magnetic induction to obtain the angular position of the corner plate 13 and return it to the initial position. The initial position is when the sensing block 131 is aligned with the angular position of the reset sensor 14. At this time, the turntable base 1 is in the horizontal direction and facing upward.

[0043] Specifically, such as Figure 3 As shown, the hub bushing of the corner disc 13 has a threaded hole, and a set screw 132 is threaded into the threaded hole. The inner end of the set screw 132 abuts against the outer wall of the cantilever tilting shaft 4.

[0044] By adding a rotary disk 13 and a reset sensor 14, the initial angular position of the rotary disk 13 can be recorded and sensed, ensuring smooth initialization of the device after power-on. By adding a set screw 132, the axial and angular adjustments of the rotary disk 13 can be easily made.

[0045] In one specific embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the adapter 11 is an L-shaped plate seat structure. An angle rib plate is provided between the top plate and the side upright plate of the adapter 11. Four mounting screws 12 are symmetrically arranged on both sides of the angle rib plate to connect the flange plate of the cantilever bracket.

[0046] By adding the corner ribs, the strength of the adapter 11 is significantly increased, ensuring that the flip-up shaft box 7 is stably installed.

[0047] The working principle of this novel dynamic tracking turntable with no blind spots is as follows: When the target object tracked by the host 3 moves to the edge of the blind zone below the turntable base 1, the electronic control system outputs a signal to start the motor 1. The motor 1 drives the worm gear 9 to rotate, which in turn drives the worm wheel 8, and the worm wheel 8 drives the cantilever tilting shaft 4 to rotate. Consequently, the turntable base 1 is disengaged from the horizontal position and tilts downwards, allowing the host 3 to bypass the obstruction of the original turntable base 1 and continuously track the target object.

[0048] In summary, this utility model's no-dead-angle dynamic tracking turntable, by adding a cantilever tilting shaft 4 and a tilting shaft box 7, allows the turntable base 1 to rotate around the axis of the cantilever tilting shaft 4. Therefore, when it is necessary to observe the field of view below the turntable base 1, simply tilting the turntable base 1 downwards allows the host unit 3 to bypass the turntable base 1 and monitor the area below. The tilting drive assembly drives the cantilever tilting shaft 4 to rotate, thus achieving the tilting of the turntable base 1. The adapter 11 connects the cantilever support and the tilting shaft box 7, clearing the area directly below the turntable base 1 for easier monitoring. This utility model's no-dead-angle dynamic tracking turntable reduces the influence of the turntable base 1, thereby reducing blind spots in monitoring. Furthermore, the rear section of the cantilever tilting shaft 4 is supported by the front bearing seat 5 and the rear bearing seat 6, which reduces the resistance during the tilting process. The bearing seats installed on the front and rear side walls of the tilting shaft box 7, relative to the inner wall, increase the spacing, ensuring that the bending strength of the cantilever tilting shaft 4 meets the requirements. The use of a worm gear reduction system achieves a larger reduction ratio and obtains greater torque, while also providing good self-locking, preventing the cantilever tilting shaft 4 from automatically tilting downwards due to the weight of the front turntable base 1. The motor 10 is a servo motor, controlled by the equipment's electrical control system, and can control the tilting angle. The addition of the angle plate 13 and reset sensor 14 allows for recording and sensing of the initial angle position of the angle plate 13, ensuring smooth initialization after power-on. The addition of the set screw 132 facilitates convenient adjustment of the axial and angular dimensions of the angle plate 13. The addition of the corner rib plate significantly increases the strength of the adapter 11, ensuring stable installation of the tilting shaft box 7.

Similar or identical parts between embodiments can be referred to interchangeably.
