Description

Technical Field

[0001] The present application relates to the technical field of remote sensing mapping, and in particular to a positioning device for remote sensing mapping. Background Art

[0002] Remote sensing is a new technology that combines sensing and remote measurement of the Earth's surface with resource management and monitoring using telemetry instruments aboard artificial satellites. Alternatively, it uses space vehicles and modern electronic and optical instruments to detect and identify distant research objects. Remote sensing mapping utilizes remote sensing technology to perform computer calculations and achieve mapping purposes. Existing remote sensing mapping methods mostly use satellites or drones to photograph the ground's geography, then use the captured images for mapping and creation. Positioning devices are often required in the process of collecting geographic information.

[0003] The patent document with announcement number CN214096042U discloses a remote sensing positioning identification device for land management surveying and mapping, in which a locator is set inside a protective box, the locator is connected to a data processor, and the data processor is connected to an alarm, so that anomalies in the surveying and mapping process can be effectively monitored and damage to the locator during the monitoring process can be avoided. However, it also has certain defects, namely, it is impossible to stably support and fix the entire device to the soil. When working in some bad weather, the entire device may be unstable due to natural factors such as wind, thereby affecting monitoring.

[0004] The patent document with publication number CN119508662A discloses a remote sensing positioning marker for land management surveying and mapping, which includes a base and a mounting seat. The mounting seat is provided with a positioning mechanism, and the base is provided with a fixing component. By setting the fixing component, the base and the support frame are vertically fixed to the soil under the action of the round rod inclined block after support, which can ensure that the device remains stable and firm during the surveying process, and prevent the equipment from shifting or tilting due to uneven ground or external force interference, thereby improving the accuracy and reliability of surveying and mapping, especially under complex or soft soil conditions, effectively ensuring the long-term stability and positioning accuracy of the equipment, which has certain positive significance. However, it still has certain shortcomings, that is, this type of positioning marker is usually fixed during marking, and is moved to another different position to continue marking after the marking is completed.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, and therefore only show the components related to the present application.

[0020] like Figure 1-13 As shown, a remote sensing mapping positioning device includes: The support platform 1 is used to set the positioning component 10; the positioning component 10 can be a remote sensing mapping identification component such as a GNSS receiver, a radar corner reflector, a laser reflection target, etc.

[0021] The fixing rod 2 is located below the support platform 1 and is connected to the support platform 1 at the top. It plays a supporting and connecting role and can be a rod or tube structure. The top can be connected and fixed to the lower part of the support platform 1 by bolts.

[0022] The rotating rod 3 is rotatably connected to the lower end of the fixed rod 2, and a sliding sleeve 7 is provided on the outside of the rotating rod that moves along its axial direction; the rotating rod 3 is located below the fixed rod 2 and can rotate with the fixed rod 2. The sliding sleeve 7 is arranged on the outside of the movable rod and can move vertically along the rotating rod 3.

[0023] At least three tripods 4 are circumferentially spaced around the rotating rod 3, one corner of the tripod 4 is slidably hinged to the sliding sleeve 7, and the other corner is hinged to the support platform 1 through the support arm 11; a walking component 6 is provided on one side of the tripod 4 corresponding to the corner connected to the support arm 11.

[0024] The tripod 4 has a triangular structure, including three corners and three side marks, one of which is slidingly hinged to the side wall of the sliding sleeve 7, and the other corner is hinged to one end of the support arm 11, and the other end of the support arm 11 is hinged to the lower edge of the support platform 1. When the sliding sleeve 7 moves up and down along the rotating rod 3, the support arm 11 can rotate relative to the support platform 1, and the tripod 4 can rotate relative to the support arm 11 and the sliding sleeve 7.

[0025] In addition, a walking assembly 6 is provided on one side of the tripod 4 corresponding to a corner connected to the support arm 11. The walking assembly 6 can be in contact with the ground in a specific state, thereby meeting the movement requirements of the entire device.

[0026] In actual situations, the sliding sleeve 7 includes two states when moving in the up and down directions relative to the rotating rod 3, one is a fixed state and the other is a moving state, and these two states are switched with each other through the movement of the sliding sleeve 7.

[0027] Specifically, for ease of explanation, Figure 1 As shown, the three sides of the tripod 4 are respectively marked as the first side 40, the second side 41 and the third side 42, and the three corners are respectively marked as the first connecting corner 43, the second connecting corner 44 and the third connecting corner 45. Please refer to Figure 1 or Figure 2 At this time, it is in a fixed state, the first side 40 is perpendicular to the support arm 11, and the second side 41 is colinear with the support arm 11. At this time, the walking component 6 set on the third side 42 is suspended in the air and does not contact the ground, while the third connecting member is in contact with the ground to fix the entire positioning device.

[0028] When the sleeve 7 moves downward, the support arm 11 rotates close to the rotating rod 3, and at the same time the first connection angle 43 synchronously descends along the sleeve 7, and the second connection angle 44 approaches the rotating rod 3 until the first side 40 is collinear with the support arm 11 and parallel to the rotating rod 3. At this time, the third connection angle 45 is suspended in the air and does not contact the ground. The fixed part of the entire device is contacted, and the walking component 6 located on the third side 42 is in contact with the ground. Under the action of external force, the entire device can move so as to go to different locations to participate in positioning and marking.

[0029] By setting the sliding sleeve 7, the rotating rod 3, the tripod 4 and the support arm 11, the entire device can realize the switching between the fixed state and the mobile state. Compared with the traditional device using a tripod, the present application solves the contradiction between fixed and mobile in the existing technology, and is particularly suitable for surveying and mapping scenarios that require frequent changes of monitoring points.

[0030] In some further embodiments, the sliding sleeve 7 is threadably engaged with a section of the outer peripheral wall of the rotating rod 3 that is relatively located below.

[0031] A section of the outer peripheral wall of the rotating rod 3 located relatively below is provided with a thread, and the sliding sleeve 7 is matched with the threaded section of the rotating rod 3.

[0032] By rotating the rotating rod 3 forward and backward, the sliding sleeve 7 can be moved up and down relative to the rotating rod 3.

[0033] In some further embodiments, a first cavity 32 is provided inside the rotating rod 3, and the first cavity 32 is arranged to pass through the axial direction of the rotating rod 3; a second cavity 20 is provided in the fixed rod 2; a drill rod 5 is axially slidably provided in the rotating rod 3, and a section of the drill rod 5 located in the second cavity 20 is screwed to the second cavity 20; the drill rod 5 rotates synchronously with the rotating rod 3.

[0034] The interior of the rotating rod 3 is hollow, i.e., the first cavity 32. The first cavity 32 is preferably a cylindrical cavity. A cylindrical cavity is also provided inside the fixed rod 2, i.e., the second cavity 20. The drill rod 5 is slidably provided in the first cavity 32 and the second cavity 20, and the top of the drill rod 5 is located in the second cavity 20 and is screwed to the second cavity 20.

[0035] When the rotating rod 3 is rotated, the rotating rod 3 drives the drill rod 5 to rotate synchronously. When the drill rod 5 rotates, it is screwed with the second cavity 20, thereby converting its own rotation into axial movement along the first cavity 32, thereby realizing the rise and fall of the drill rod 5.

[0036] It should be noted that when the driving rotating rod 3 is rotated in a certain direction, the sliding sleeve 7 moves up and the corresponding drill rod 5 moves down; when the driving rotating rod 3 is rotated in the other opposite direction, the sliding sleeve 7 moves down and the corresponding drill rod 5 moves up; the above mechanism is realized by setting different thread rotation directions.

[0037] A spiral blade 50 is provided at the lower end of the drill rod 5 for drilling into the ground to limit the entire device. When the drill rod 5 drives the spiral blade 50 to descend, the reaction force formed by the ground on the spiral blade 50 will drive the device to move downward, thereby ensuring the supporting performance of the third connection angle 45 on the ground in a fixed state.

[0038] In some further embodiments, a clamping groove 320 is provided on the inner wall of the first cavity 32 along the axial direction of the rotating rod 3 , and a clamping strip 51 is provided on the outer peripheral wall of the drill rod 5 , and the clamping groove 320 and the clamping strip 51 are slidably engaged.

[0039] The sliding and anti-rotation movement between the drill rod 5 and the first cavity 32 is achieved through the clamping strip 51 and the clamping groove 320, that is, the clamping strip 51 is provided on the outer peripheral wall of the drill rod 5, and the clamping groove 320 is correspondingly provided on the inner wall of the first cavity 32, and the clamping strip 51 is slidably set in the clamping groove 320.

[0040] In some further embodiments, an annular screw block 21 is provided inside the second cavity 20 . The annular screw block 21 is integrally provided with the fixing rod 2 , and the drill rod 5 is screwed to the annular screw block 21 .

[0041] The thickness of the annular screw connection block 21 is smaller than the axial length of the second cavity 20 to reduce the screw connection friction between the two.

[0042] In some further embodiments, a sliding handle 70 is provided on the outer peripheral wall of the sliding sleeve 7, and a sliding groove 71 is provided on the sliding handle 70 along the moving direction of the sliding sleeve 7. The sliding groove 71 is arranged to pass through the thickness direction of the sliding handle 70, and a hinge hole is provided on the tripod 4. A pin shaft 75 is passed through the sliding groove 71 and the hinge hole.

[0043] Since the outdoor ground is rugged and uneven, in order to ensure that the third connecting frames of the three tripods 4 can form abutment with the uneven ground, a pin shaft 75 and a slide groove 71 are specially provided, so that when the sliding sleeve 7 stops moving relative to the sliding shaft, the tripod 4 can perform a certain rotation adjustment according to the actual situation of the ground, thereby ensuring the support stability of the entire device.

[0044] In some further embodiments, a first spring 72 is provided at the bottom of the sliding groove 71 , and the top of the first spring 72 is disposed in contact with the bottom of the pin shaft 75 .

[0045] To ensure that the entire device has a certain degree of "tension" after being fixed, i.e., elastic limiting, a first spring 72 is provided at the bottom of the slide 71. When the drill rod 5 is pressed downward, the slide 71 is configured to allow the pin 75 to move downward relative to the slide 71. In order to prevent the tripod 4 from hindering the downward movement of the rotating rod 3 driven by the drill rod 5 and to ensure elastic limiting within the entire device, the elastic force of the first spring 72 will hinder the rotational movement of the tripod 4 when it contacts the ground, thereby locking the entire device to the ground and further ensuring the strength of the fixation.

[0046] It should be noted that when the tripod 4 switches from a mobile state to a fixed state, the entire device has a tendency to rise, and at this time the drill rod 5 drives the spiral blade 50 to have a downward trend, thereby making the rotating rod 3 have a downward trend, so as to form the so-called locked state with the ground.

[0047] In some further embodiments, a bottom opening 73 is provided on one side of the slide groove 71 away from the rotating rod 3; a mounting hole is provided at the bottom of the slide groove 71 through the sliding handle 70, and an abutment member 74 is screwed in the mounting hole. The bottom of the first spring 72 is located in the mounting hole and is connected to the top of the abutment member 74.

[0048] The abutment 74 can be a top screw or a bolt. When the abutment 74 rotates toward the inside of the slide groove 71, the length of the first spring 72 in the slide groove 71 will increase to ensure that when the first spring 72 is fully in a compressed state, it can still interfere with the opening 73 to prevent the pin shaft 75 from slipping out of the slide groove 71.

[0049] In addition to the above-mentioned fixed state and mobile state, the tripod 4 also has a third state, namely the storage state. When the entire device needs to be stored, first rotate the abutment 74 in the direction away from the slide groove 71 until the length of the first spring 72 in the maximum compression state is less than the height of the opening 73 so that the pin shaft 75 can be disengaged from the opening 73 and from the inside of the slide groove 71. After disengagement, continue to rotate the tripod 4 in the direction away from the rotating rod 3 until the second side 41 of the entire tripod 4 is completely overlapped with the support arm 11. At this time, the support arm 11 and the second side 41 are both arranged in contact with the rotating rod 3. The entire device in this state has the smallest horizontal plane size, which can make the entire device more convenient during storage or transportation.

[0050] In some further embodiments, the walking assembly 6 includes a rotating disk, an articulated arm 60, a roller 61 and a shock-absorbing rod 62; the rotating disk is rotatably set on the tripod 4, one end of the articulated arm 60 is hinged to the rotating disk, and the other end is rotatably connected to the roller 61; one end of the shock-absorbing rod 62 is hinged to the articulated arm 60, and the other end is hinged to the tripod 4.

[0051] In the moving state, the roller 61 in the walking assembly 6 is in contact with the ground, and the shock absorbing rod 62 can be extended and retracted, thereby ensuring that the entire device has a certain shock absorbing performance.

[0052] The shock absorbing rod 62 may be a third spring.

[0053] In some further embodiments, a rotating sleeve 31 is provided on the top of the rotating rod 3 , the rotating sleeve 31 is integrally arranged with the rotating rod 3 , a second spring 30 is provided between the sliding sleeve 7 and the rotating sleeve 31 , and the second spring 30 is sleeved on the rotating rod 3 .

[0054] A rotating sleeve 31 is integrally provided on the top of the rotating rod 3 , and the rotating sleeve 31 and the fixed rod 2 can be connected to each other via a bearing.

[0055] Two ends of the second spring 30 abut against the sliding sleeve 7 and the rotating sleeve 31 respectively.

[0056] In some other embodiments, the thread between the sleeve 7 and the rotating rod 3 is a multi-thread thread, and the number of spiral threads is at least two. Moreover, the more spiral threads there are, the lower the error change in the initial position of the drill rod 5 will be each time the sleeve 7 and the rotating rod 3 are disengaged and re-threaded.

[0057] Working principle: When the device is in motion, the support arms 11 are aligned with the first side 40 and are in contact with the rotating rod 3. The drill rod 5 is now located within the first cavity 32 and the second cavity 20, and the entire device is in contact with the ground only via the three rollers 61. During movement, the shock-absorbing rods 62 provide a certain degree of shock absorption, thereby increasing the stability of the entire positioning device.

[0058] Afterwards, if the positioning device moves to the designated marking position, the rotating sleeve 31 is rotated first. When the rotating sleeve 31 rotates, the rotating sleeve 31 drives the rotating rod 3 to rotate. Since the sliding sleeve 7 is located on a section of the rotating rod 3 where a thread is set when it was previously fixed, rotating the rotating rod 3 will drive the sliding sleeve 7 to move upward. At the same time, the tripod 4 rotates, gradually transforming from the original first side 40 being colinear with the support arm 11 to the second side 41 being colinear with the support arm 11. At the same time, the roller 61 will also be suspended synchronously, and instead the third connecting angle 45 will abut against the ground.

[0059] When the sliding sleeve 7 gradually rises under the rotation of the rotating rod 3, the rotating rod 3 synchronously drives the drill rod 5 to rotate. Since the drill rod 5 is threadedly engaged with the annular screw block 21 located in the fixed rod 2, the drill rod 5 will move downward at the same time and extend out of the first cavity 32, and then drill into the ground through the spiral blade 50.

[0060] During the entire process, as the roller 61 moves from contacting the ground to being suspended, then to contacting the ground at the third connection angle 45, and subsequently until the support arm 11 is collinear with the second side 41, the entire device tends to move upward. However, the drill rod 5 always rotates and moves downward. By combining and analyzing the corresponding movements of the two, it can be determined that there is resistance when the drill rod 5 descends and rotates into the ground, that is, the force acting to lift the entire device. In other words, during the entire process, the first connection angle 43 in the tripod 4 will be hindered from rising. As the drill rod 5 continues to descend, the first spring 72 will be compressed. That is, the more the first spring 72 is compressed, the greater the combined force between the entire device and the ground (that is, the grip on the ground formed by the combination of the drill rod 5 driving the entire device downward and the reaction force after the compression of the first spring 72 driving the entire device upward) will be.

[0061] Therefore, during the entire process, the first spring 72 can, on the one hand, limit the pin 75 to prevent the pin 75 from slipping out of the opening 73 , and on the other hand, increase the force of the entire device on the ground to ensure the stability of the entire device.

[0062] In addition, during the above-mentioned change process, the rotation of the rotating rod 3 drives the sliding sleeve 7 to move upward, and the sliding sleeve 7 will gradually disengage from the threaded connection with the outer peripheral wall of the rotating rod 3 and enter the part of the rotating rod 3 where no thread is set. At this time, the sliding sleeve 7 will no longer be threaded with the threaded part of the rotating rod 3.

[0063] When the sliding sleeve 7 is disengaged from the threaded section of the rotating rod 3 , the supporting arm 11 is exactly colinear with the second side edge 41 .

[0064] Assuming the sliding sleeve 7 continues to rise, the entire tripod 4 has a tendency to rotate toward the rotating rod 3, which is equivalent to the increase in the elasticity of the first spring 72. However, the sliding sleeve 7 is already resisted by the second spring 30 during its upward movement. Therefore, the first spring 72 and the second spring 30 can provide a certain degree of adaptive correction for the tripod 4 in the fixed state. That is, when the entire device is in the fixed state and is subjected to external forces such as wind, rain, etc., it tends to tilt, the first spring 72 and the second spring 30 can form a certain elastic limit to the movement of the tripod 4. If the external force causes the entire device to tilt toward the side where one of the tripods 4 is located, the elastic potential energy of the first spring 72 will increase and hinder this trend. The rotational movement of the other two tripods 4 toward the rotating rod 3 caused by the tilting process will be hindered by the compression of the sliding sleeve 7 by the second spring 30. Under the action of external forces, the first spring 72 and the second spring 30 will adaptively correct the skew of the entire device to ensure its stability. At the same time, the design of the first spring 72 and the second spring 30 also greatly increases the device's resistance to external forces.

[0065] It should be noted that the process of the spiral blade 50 in the drill rod 5 rotating into the ground cannot directly drive the entire device to descend. The reason why the drill rod 5 can bring a downward effect on the entire device with a certain trend is due to the rotation of the tripod 4.

[0066] When the state is changed from a fixed state to a mobile state, the second spring 30 can always exert a downward force on the sleeve 7, so that the rotating rod 3 can be screwed with the sleeve 7 at the same time as it starts to rotate. In order to avoid the rotating rod 3 from being unable to be screwed with the sleeve 7 at the first time and to reduce the screw connection error caused by multiple switching, the present application specially adopts a multi-thread thread for the thread in the rotating rod 3, that is, to reduce the influence of the error as much as possible, while ensuring that the screw connection is timely and accurate.

[0067] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of this application.
