Description

Technical Field

[0001] This invention relates to the field of surveying equipment technology, and in particular to an intelligent land surveying slope instrument and its surveying method. Background Technology

[0002] During land surveying, surveyors use a slope meter to measure the slope of the slope to be surveyed, thereby obtaining the slope information of the slope to be surveyed. In order to ensure the accuracy of the slope information, surveyors need to hold the slope meter and place it at different positions on the slope, then read and record the data information on the slope meter. This requires surveyors to hold the traditional slope meter and constantly change positions, resulting in a large workload for surveying. In addition, surveyors holding the traditional slope meter cannot measure the slope at higher points on the slope, resulting in incomplete slope surveying data and inaccurate slope information of the surveyed slope.

[0003] Therefore, there is a need for an intelligent land surveying slope instrument and its surveying method to solve the above problems. Summary of the Invention

[0004] This invention proposes an intelligent land surveying slope meter and its surveying method. By swinging the surveying plate, surveyors can measure the slope at multiple locations on the slope from the same position, increasing the range of slope measurement, reducing the surveying workload of surveyors, and ensuring the comprehensiveness of slope surveying data.

[0005] The technical solution of this invention is implemented as follows:

[0006] An intelligent land surveying slope meter includes a housing, on which a swinging surveying plate for measuring the slope at multiple locations is constrained and installed. The swinging surveying plate is horizontally set, and a surveying element is fixedly installed at each end of the swinging surveying plate.

[0007] The bottom of both ends of the swinging surveying plate is fixedly installed with a vertically arranged first rotating column and a second rotating column, respectively. A first limiting seat for blocking the first rotating column at a first constraint position is fixedly installed on the housing. A second limiting seat for blocking the second rotating column at a second constraint position is fixedly installed on the housing. A limiting rod for alternately limiting the first rotating column and the second rotating column after being blocked is slidably installed on the housing in the horizontal direction.

[0008] A horizontally arranged sliding plate is slidably installed on the housing along the extension direction of the limiting rod. The sliding plate is located on one side of the limiting rod. A rotating plate is horizontally arranged below the sliding plate. A rotating shaft is fixedly installed on the rotating plate. The rotating shaft passes through the sliding plate and is fixedly connected to a horizontally arranged rotating arm. A guide wheel is fixedly installed at the free end of the rotating arm. A guide groove is fixedly installed on the housing. The guide wheel is slidably installed in the guide groove. The guide groove includes an integrally formed straight groove and a reversing inclined groove. A linkage drive assembly is provided between the swinging surveying plate and the rotating plate.

[0009] As a preferred technical solution, the linkage drive assembly includes a drive motor fixedly mounted on the rotating plate, a first link fixedly connected to the motor shaft of the drive motor, a second link hinged to the free end of the first link, and the free end of the second link hinged to the swinging surveying plate.

[0010] As a preferred technical solution, the first limiting seat and the second limiting seat are symmetrically arranged. The first limiting seat is provided with a first limiting groove that matches the first rotating column, and the second limiting seat is provided with a second limiting groove that matches the second rotating column.

[0011] As a preferred technical solution, the first limiting seat and the second limiting seat are respectively provided with a third limiting groove that is adapted to the end of the limiting rod.

[0012] As a preferred technical solution, a slide rail is horizontally arranged on the housing, the sliding plate is slidably mounted on the slide rail, a horizontally arranged lead screw is rotatably mounted on the housing, a nut is threaded onto the lead screw, the nut is fixedly mounted on the bottom of the sliding plate, and a lead screw drive motor is fixedly mounted on the housing, the motor shaft of the lead screw drive motor is connected to the lead screw in a transmission connection.

[0013] The surveying method of the intelligent land surveying slope instrument specifically includes the following steps:

[0014] S1. The slope meter is in its initial state: the first rotating column is limited to the first constraint position by the first limiting seat and the limiting rod, the second rotating column is in the unlocked state, and the guide wheel is located in the straight groove.

[0015] S2. Place the slope meter on the slope to be measured. In the initial state, the slope information of points A and B is obtained by measuring the two measuring elements. Under the drive of the linkage drive assembly and the sliding of the sliding plate, the swing measuring plate rotates clockwise around the first rotating column as the rotation axis by a certain angle. During this process, the slope information of points C and D is obtained by measuring the measuring elements at the free end.

[0016] S3. The swinging surveying plate returns to its initial state, the limiting rod slides, the second rotating column is limited to the second constraint position, and the first rotating column is in the unlocked state.

[0017] S4. The sliding plate slides towards the second limiting seat, the guide wheel enters the reversing groove, and the rotating plate rotates 90 degrees counterclockwise.

[0018] S5. Driven by the linkage drive assembly, the swinging surveying plate rotates 180 degrees counterclockwise around the second rotating column as the rotation axis. During this process, the slope information of points E, F, G and H is obtained by the measurement of the surveying element at the free end, that is, the slope information detection of multiple positions of the slope is completed. The slope meter returns to the initial state to prepare for the next slope measurement.

[0019] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0020] Because the intelligent land surveying slope meter includes a swinging surveying plate, during the slope measurement process, the swinging surveying plate initially maps the slope information of points A and B through two surveying elements. Through the cooperation of the linkage drive assembly and the sliding plate, the swinging surveying plate rotates clockwise around the first rotating column as the axis from the initial state to the upper swing endpoint. During this process, the slope information of points C and D is measured. The swinging surveying plate returns to the initial state and rotates counterclockwise around the second rotating column as the axis to the lower swing endpoint. During this process, the slope information of points E, F, G, and H is measured, thus completing the slope measurement at different locations on the slope to be surveyed. The swinging surveying plate then returns to the initial position.

[0021] In this invention, by swinging the oscillating surveying board, surveyors can measure the slope at multiple locations on the slope from the same position, which increases the range of slope measurement, reduces the surveyor's workload, and ensures the comprehensiveness of the slope surveying data.

[0022] Since the intelligent land surveying slope meter includes a swinging surveying plate, this invention cleverly utilizes a horizontally sliding limiting rod, as well as a first limiting seat and a second limiting seat, to alternately constrain both ends of the swinging surveying plate. In conjunction with the sliding plate and the linkage drive assembly, the surveying plate can rotate around the first and second limiting columns as axes. During the rotation, the slope is measured at multiple positions, allowing surveyors to measure the slope at different points on the slope from the same location. This avoids surveyors constantly changing surveying positions, thereby reducing the surveyor's workload and improving the efficiency of land slope surveying.

[0023] Since the intelligent land surveying slope meter includes a linkage drive assembly, in this invention, the drive motor drives the first linkage to rotate, the first linkage drives the second linkage to rotate, and the second linkage drives the swinging surveying plate to rotate. At the same time, through the cooperation of the sliding plate, guide wheel and guide groove, the position rotation of the drive motor is realized, thereby increasing the swing angle of the swinging surveying plate, so that this slope meter can be used to measure the slope of higher points on the slope, and further improves the slope measurement range of this slope meter.

[0024] Through the coordinated operation of the linkage drive assembly, the limiting rod, the first limiting seat, and the second limiting seat, the swinging surveying plate alternately swings around the first and second rotating columns as rotation axes. At the same time, through the cooperation of the sliding plate, the guide wheel, and the guide groove, the movement and rotation of the drive motor are realized, thereby increasing the swing angle of the swinging surveying plate, improving the slope measurement range of this slope meter, and ensuring the comprehensiveness of the slope surveying data. By analyzing the comprehensive slope surveying data, surveyors can obtain accurate slope information of the surveyed slope, making land slope surveying more accurate. Attached Figure Description
