Description

Technical Field

[0001] This utility model relates to the field of geographic information surveying and mapping equipment technology, specifically a remote sensor bracket. Background Technology

[0002] In fields such as surveying, geological exploration, engineering construction, and environmental monitoring, remote sensors (such as total stations, lidar, and multispectral sensors) are key equipment for acquiring accurate spatial information data. These devices typically need to be mounted on a stable tripod for operation.

[0003] Currently, existing remote sensor supports have limitations in various practical application environments and operating conditions. For example, in rugged mountainous areas, soft riverbeds, gravelly ground, or outdoor environments covered by vegetation, as well as when setting up the instrument on temporary ground at construction sites, traditional three-ball-mounted and manual leveling mechanisms often require operators to repeatedly and meticulously adjust the length of the three support legs to achieve a preliminary level position. This process is time-consuming and labor-intensive. Especially on soft or uneven ground, the support may sink slightly during the adjustment process, causing the level position to be disrupted and requiring repeated adjustments, which greatly reduces the efficiency of field work, especially in tasks that require frequent point-to-point measurements.

[0004] Furthermore, in emergency geological disaster sites (such as flash floods, landslides, collapses, mudslides, and fires), when conducting emergency mapping, dynamic monitoring, or operations that require racing against time, the entire erection process of traditional supports, from deployment and stabilization to precise leveling, is time-consuming and cannot meet the needs of rapid response and real-time measurement, thus becoming a bottleneck in improving overall operational efficiency.

[0005] While some remote sensor mounts are equipped with correction systems (GNSS, IMS), which can be deployed quickly, their accuracy is highly dependent on the accuracy and calibration of the POS system. For surveying equipment with extremely high requirements, ground control points are also needed for purification. More importantly, they need to be powered by batteries to operate. In long-term outdoor environments, especially in harsh conditions, the battery's power supply capacity must be considered in real time, and solar and wind power must be used to supplement power in a timely manner, making it difficult to meet the needs of long-term outdoor surveying operations.

[0006] Therefore, there is an urgent need for a technology that can provide rapid deployment and fast adaptive leveling capabilities without the need for electricity under complex terrain conditions, so as to significantly shorten the setup time and level complex phenomena, overcome the above-mentioned shortcomings of existing technologies, and meet the needs of modern efficient and accurate surveying and mapping operations. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a remote sensor bracket, comprising:

[0008] The tripod consists of a ring disc and three support rods with tapered heads arranged axially on the side, forming a rigid support structure for the entire equipment. The tapered heads are installed at the bottom of the support rods by threaded connection. When the support rods are unfolded and placed on the ground, the tapered heads are inserted into the ground. The tight engagement between the tapered surfaces and the soil ensures the stability of the tripod support.

[0009] The support component is located at the bottom space of the annular disk's axis, and its telescopic movement adjusts the horizontal height of the surveying instrument above, while also providing convenient storage and carrying capabilities.

[0010] The control component is located above the support component and is capable of adaptively adjusting the horizontal angle of the surveying instrument above.

[0011] The remote sensor body is positioned above the support assembly, and the horizontal angle of the remote sensor body can be quickly adjusted using the horizontal adaptive adjustment function of the control assembly.

[0012] Preferably, three U-shaped plates are axially distributed on the side of the annular disk, and the top of each of the three support rods is fixed with a round button. The round button is rotatably connected inside the U-shaped plate to realize the function of unfolding support and folding of the support rods.

[0013] Preferably, a spring pin is fixed above the U-shaped plate, and multiple positioning holes are axially distributed on the side of the round button. When the support rod is extended to the required angle, the output end of the spring pin automatically pops out under the action of the spring force and inserts into the corresponding positioning hole, thereby realizing the positioning and locking of the extension angle of the support rod and ensuring the stability of the support.

[0014] Preferably, the support assembly includes a sleeve fixed to the inner diameter edge of the annular disc shaft. Multiple connecting tubes, arranged in descending order of diameter, are movably fitted into the sleeve to form a telescopic sleeve structure. At one end of the connecting tubes, a spring-loaded locking mechanism is built into the interface where the smaller diameter connecting tube is inserted into the larger diameter connecting tube. The larger diameter connecting tube also has a positioning hole at the corresponding position. When the inner connecting rods are pulled outwards section by section, after reaching the required height, the spring-loaded locking mechanism automatically engages with the positioning hole on the corresponding connecting tube to achieve height locking. Pressing the spring-loaded locking mechanism unlocks the connecting rods, allowing them to be pushed back in sequentially.

[0015] Preferably, the control component includes a base and a top cover that are threadedly connected to each other. The base is fixed to the top of the innermost connecting rod of the support component. The base and the top cover are circular hollow grooves, and are movably connected to a traction mechanism for guiding and adjusting the horizontal angle and a ball-rotating mechanism for adaptively adjusting the horizontality according to the guiding and gravity principle.

[0016] Preferably, the traction mechanism includes two arc-shaped rods arranged in a cross shape to form a cross structure, and a connecting button is fixed below the intersection. A connecting hole is opened on the axis of the base, and the connecting button is rotatably connected in the connecting hole, so that the cross structure can rotate freely and smoothly in the horizontal direction within the base.

[0017] One of the curved rods has a ball bearing rotatably connected to both ends. Another curved rod has a curved groove along its length, and a sliding plate is slidably connected in the groove. The two ends of the sliding plate are rotatably connected to the ball bearing 2. When the entire support is placed on the ground, the sliding plate slides in the curved groove due to the low friction of the ball bearing 2, caused by the tilting phenomenon. At the same time, the cross structure rotates horizontally in the base to the corresponding angle due to the center of gravity caused by the displacement of the sliding plate in the tilting direction.

[0018] Preferably, the ball-rotating mechanism includes a ball movably connected between the base and the top cover. Multiple rotating balls are distributed on the inner side of the top cover. The ball fits against the sides of the first ball, the second ball, and the rotating balls, forming multi-point low friction and support, so that the ball can rotate smoothly in the forward direction.

[0019] Preferably, an iron plate is fixed on the sliding plate, and a magnetic plate is fixed at the bottom of the rotating ball, away from the axis. The magnetic plate and the iron plate are attracted to each other. When the sliding plate slides in the tilting direction, the magnetic attraction between the magnetic plate and the iron plate guides the rotating ball to rotate towards the lowest point after tilting. This enables adaptive horizontal adjustment of the remote sensor body installed above. Furthermore, the weight block fixed inside the rotating ball and above the magnetic plate allows the rotating ball to react quickly and rotate due to the combination of the off-center design and the gravity of the earth, while also enhancing the stability of the rotating ball.

[0020] Preferably, a positioning rod is threadedly connected to the side of the top cover. The positioning rod fits against the side of the rotating ball. After the rotating ball is adjusted to the corresponding angle, the front end of the positioning rod is tightly attached to the corresponding position on the side of the rotating ball after rotation, thereby locking the angle of the rotating ball after adjustment, preventing shaking during operation and avoiding affecting the geographic survey data.

[0021] Preferably, a protruding button is fixed on the rotating ball, and a circular groove is opened on the top cover. The protruding button is movably connected in the circular groove. The diameter of the protruding button is smaller than the inner diameter of the circular groove, so that when the rotating ball rotates, the protruding button rotates in the circular groove, limiting the rotation range of the rotating ball relative to the top cover and preventing excessive twisting.

[0022] Preferably, a mounting platform is fixed on the protruding button, and a fixing rod is provided on the mounting platform. The bottom of the remote sensor body is threadedly connected to the side of the fixing rod and fits against the mounting platform. The assembly of the remote sensor body with the mounting platform is achieved by threading the screw hole at the bottom of the remote sensor body to the side of the fixing rod, which provides stable installation and support for the remote sensor body. At the same time, when the rotating ball rotates, it drives the remote sensor body to smoothly adjust the horizontal angle.

[0023] Compared with the prior art, the present invention provides a remote sensor bracket, which has the following beneficial effects:

[0024] 1. This remote sensor support adopts a unique control component that combines magnetic attraction guidance, low friction support and the principle of gravity attraction under eccentric gravity physical conditions. Without considering the ground tilt curvature, the rotating ball can automatically and quickly adjust the remote sensor body to a horizontal state, improving the installation efficiency. It is especially suitable for environments with uneven terrain, frequent movement, or emergency geographical disasters, effectively improving the practicality of the support.

[0025] 2. The remote sensor bracket, through the mechanical structure of the control components and physical functional mechanisms installed in the bracket, allows each component to operate without a power supply, thus enabling long-term use in harsh outdoor environments and further improving the practicality of the bracket.

[0026] 3. The remote sensor bracket adopts a multi-stage linkage with a spring-loaded locking mechanism, and features a foldable support rod and an adaptive leveling component. This design makes the unfolding, locking, height adjustment, leveling, and storage processes convenient and user-friendly. Attached Figure Description

[0038] 4. Remote sensor body. Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0040] Example 1

[0041] Please see Figure 1 - Figure 7 As shown, the remote sensor bracket proposed in this embodiment includes:

[0042] Tripod 1 includes an annular disc 11 and three support rods 12 with tapered heads arranged axially on the side. The spread angle of the support rods ranges from 45° to 75° (experiments have verified that the spring pin positioning stability is optimal within this range), forming a rigid support structure for the entire equipment. The bottom end of the support rod 12 is equipped with a tapered head with a 60° cone angle through a threaded connection. In sandy loam soil (compaction degree ≥85%), the tapered head can withstand a vertical load ≥500N when inserted into the ground. The tight interlocking between the cone surface and the soil ensures the stability of the tripod 1.

[0043] For details, please refer to Figure 3 As shown, three U-shaped plates 111 are axially distributed on the side of the annular disk 11, and the top of each of the three support rods 12 is fixed with a round button 121. The round button 121 is rotatably connected inside the U-shaped plate 111 to realize the function of unfolding support and folding of the support rods 12.

[0044] In addition, a spring pin 13 is fixed above the U-shaped plate 111, and multiple positioning holes 122 are axially distributed on the side of the round button 121. The spring force of the spring pin 13 is 50N±5N. When the support rod 12 is extended to the required angle in the range of 45°-75°, its output end automatically pops out and inserts into the corresponding positioning hole 122 under the action of the spring force, which can provide a torsional torque of **≥100N·mm**, realize the positioning and locking of the extension angle of the support rod 12, and ensure the stability of the support.

[0045] The support component 2 is located at the bottom space of the axis of the ring disk 11, and can adjust the horizontal height of the surveying instrument above through telescopic movement, as well as provide convenient storage and carrying functions.

[0046] See Figure 1 and Figure 3 As shown, it includes a sleeve 21 fixed to the inner diameter edge of the annular disk 11. Multiple connecting tubes 22, arranged in descending order of diameter, are movably fitted into the sleeve 21, forming a telescopic sleeve structure. Its maximum extension height is 1.2m-1.8m (a total of 3 connecting tube sections, each with a telescopic range of 0.2m). At one end of the connecting tubes 22, a spring-loaded locking mechanism 23 is built into the interface where a smaller diameter connecting tube 22 is inserted into a larger diameter connecting tube 22. The spring-loaded locking mechanism 23 can withstand an axial load ≥300N when locked. When the inner connecting tubes 22 are pulled outwards section by section, upon reaching the desired height, the spring-loaded locking mechanism 23 automatically engages with the positioning hole on the corresponding connecting tube 22, achieving height locking. Pressing the spring-loaded locking mechanism 23 unlocks the tubes, allowing them to be pushed back in sequentially.

[0047] It should be further noted that, regarding environmental adaptability, the connecting pipe 22 is made of 6061 aluminum alloy (hard anodized), and its locking reliability remains unchanged within a temperature range of -20℃ to 50℃; it also performs reliably in dusty environments (dust concentration ≤10mg / m³). 3 (Mud and water depth ≤ 5mm)** The dustproof and waterproof rating reaches IP54, which can guarantee at least 500 expansion and contraction operations without jamming.

[0048] Adjustment component 3: Located above support component 2, it has the ability to adaptively adjust the horizontal angle of the surveying instrument above, and its maximum self-adjustable tilt angle is ±15° (within this range, gravity and magnetic attraction can effectively drive the rotating ball back to the center).

[0049] See Figure 4 - Figure 7As shown, it includes a base 31 and a top cover 32 that are threadedly connected to each other. The base 31 is fixed to the top of the innermost connecting pipe 22 of the support assembly 2. The base 31 and the top cover 32 are circular hollow grooves, and are movably connected to a traction mechanism 33 for guiding and adjusting the horizontal angle and a ball-rotating mechanism 34 for adaptively adjusting the horizontality according to the guiding and gravity principle.

[0050] The traction mechanism 33 includes two intersecting arc-shaped rods 331 (made of 45# steel with a bending strength ≥600MPa) to form a cross structure. A connecting button 3313 is fixed below the intersection. A connecting hole 311 is provided on the axis of the base 31. The connecting button 3313 is rotatably connected in the connecting hole 311, so that the cross structure can rotate freely and smoothly in the horizontal direction within the base 31.

[0051] One of the arc-shaped rods 331 has ball bearings 3311 rotatably connected to both ends. Another arc-shaped rod 331 has an arc-shaped groove 3312 along its length. A sliding plate 332 is slidably connected in the arc-shaped groove 3312. Ball bearings 3321 (made of chrome steel) are rotatably connected to both ends of the sliding plate 332. The rolling friction coefficient between the sliding plate 332 and the arc-shaped groove 3312 is ≤0.0. When the entire support is placed on the ground, the sliding plate 332 slides in the arc-shaped groove 3312 due to the low friction rolling effect of the ball bearings 3321. At the same time, the cross structure rotates horizontally in the base 31 to the corresponding angle due to the center of gravity caused by the displacement of the sliding plate 332 in the tilt direction.

[0052] The rotating ball mechanism 34 includes a rotating ball 341 that is movably connected between the base 31 and the top cover 32. Multiple rotating balls 321 made of silicon nitride ceramic are distributed on the inner side of the top cover 32. The rotating ball 341 fits against the sides of the first ball 3311, the second ball 3321 and the rotating ball 321, forming multi-point low friction and support, so that the rotating ball 341 can rotate smoothly in the forward direction.

[0053] Furthermore, an iron plate 3322 is fixed on the sliding plate 332, and a magnetic plate 345 is fixed at the bottom of the rotating ball 341 away from the axis. When the magnetic plate and the iron plate are 5mm-10mm apart, the magnetic attraction force is 80N-120N. When the sliding plate 332 slides in the tilting direction, the magnetic attraction force between the magnetic plate 345 and the iron plate 3322 guides the rotating ball 341 to rotate towards the lowest point of gravity after tilting and then stop, realizing the adaptive angle horizontal adjustment of the remote sensor body 4 installed above. Through the 0.5kg weight block 346 (eccentricity is 1 / 3 of the radius of the rotating ball) fixed inside the rotating ball 341 and above the magnetic plate 345, relying on the off-center design and the cooperation of the gravity force, the rotating ball 341 can quickly react and rotate within 3 seconds to complete the self-leveling and return to center.

[0054] In addition, a ball-shaped positioning rod 323 (M8 thread) is threadedly connected to the side of the top cover 32. The positioning rod 323 fits against the side of the rotating ball 341. After the rotating ball 341 is adjusted to the corresponding angle, the positioning rod 323 rotates clockwise, and its front end presses tightly against the side of the rotating ball 341 with a pressure of ≥200N, which can provide an anti-slip torque of ≥20N·m to lock the angle of the rotating ball 341 after adjustment, preventing shaking during operation and avoiding affecting the geographic survey data. When the positioning rod 323 rotates counterclockwise, its front end disengages from the rotating ball 341. At this time, the rotating ball 341 can adaptively rotate to the horizontal angle again according to the actual tilt angle.

[0055] The remote sensor body 4 is positioned above the support component 2 and can bear a weight range of 5kg-15kg (within this range, the reliability of the ball-rotating mechanism and the locking of the positioning rod meets the requirements). The horizontal angle of the remote sensor body 4 can be quickly adjusted using the horizontal adaptive adjustment function of the control component 3.

[0056] A protruding button 342 is fixed on the rotating ball 341, and a circular groove 322 is provided on the top cover 32. The diameter of the protruding button 342 is smaller than the inner diameter of the circular groove 322. Thus, when the rotating ball 341 rotates, the protruding button 342 rotates within the circular groove 322, limiting the rotation range of the rotating ball 341 relative to the top cover 32 and preventing excessive twisting.

[0057] A mounting platform 343 is fixed on the protruding button 342. A fixing rod 344 is provided on the mounting platform 343. The bottom of the remote sensor body 4 is threadedly connected to the side of the fixing rod 344 and fits against the mounting platform 343. The installation and assembly of the remote sensor body 4 with the mounting platform 343 are achieved by threading the screw hole at the bottom of the remote sensor body 4 to the side of the fixing rod 344. This provides a stable installation and support for the remote sensor body 4. At the same time, when the rotating ball 341 rotates, it drives the remote sensor body 4 to smoothly adjust the horizontal angle.

[0058] The working principle of the remote sensor bracket proposed in this embodiment includes the following steps:

[0059] S1: Installation of the remote sensor body 4: Align the threaded hole at the bottom of the remote sensor body 4 with the fixing rod 344 at the top of the mounting platform 343 and tighten it to ensure that its bottom is firmly attached to the mounting platform 343 and that the connection is reliable.

[0060] S2: Deploying and securing the tripod 1: Take the tripod 1 out of its stored state, grasp the support rod 12 and rotate it outward to the desired angle of 45°-75° until the desired opening angle is reached. During the deployment process, the round button 121 at the top of the support rod 12 rotates within the U-shaped plate 111. When it rotates to the appropriate angle position, the spring pin 13 on the U-shaped plate 111 automatically pops out under the action of the spring force, and its output end is inserted into the positioning hole 122 corresponding to the side wall of the round button 121, locking the support rod 12 at the deployment angle. Then place the tripod in this state on the ground and press down or step on the connection between the ring disc 11 and the support rod 12 to insert the tapered head at the bottom of the support rod 12 into the ground. The tapered surface increases the contact and biting force, providing stable rigid support.

[0061] S3: Adjust the height of the remote sensor body 4. Pull the mounting platform 343 upward to extend the multiple connecting pipes 22 from the inner layer to the outer layer to the required height (maximum 1.8m). At this time, the spring-loaded mechanism 23 automatically locks with the corresponding positioning hole to fix the current height. If you need to lower the height, press the release button of the spring-loaded mechanism 23, and then gently press down on the innermost connecting pipe 22 to retract the adjacent connecting pipes 22, thereby adjusting the height.

[0062] S4: Adaptive horizontal adjustment. Place the support on a simulated slope (sand loam, compaction degree 85%) with an inclination angle of 15°. The remote sensor body 4 has a mass of 10kg. At this time, the sliding plate 332 slides in the inclined direction in the arc groove 3312 under the influence of the inclined gravity. The cross structure rotates in the inclined direction. The magnetic attraction force (80N-120N) between the iron plate 3322 and the magnetic plate 345 guides the rotating ball 341 to rotate. The remote sensor body 4 reaches the horizontal position within 3 seconds (horizontal error ≤0.1°). Tighten the positioning rod 323 and verify the locking torque ≥20N・m with a torque wrench. Then carry out geographic information mapping operation.

[0063] S5: After use, press the release button on the spring buckle mechanism 23 to retract the multiple connecting tubes 22 into the interior section by section. Rotate the remote sensor body 4 in the opposite direction to separate it from the mounting platform 343. Then press each support rod 12 to disengage the output end of the spring pin 13 from the current positioning hole 122 until the support rod 12 is completely in contact with the side of the sleeve 21. At this time, the output end of the spring pin 13 is inserted into the corresponding positioning hole 122 for locking, so that the bracket is completely retracted and put into the provided storage bag to reduce the volume and make it easy to carry.

[0064] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
