Although these devices are accurate, they are complex and time-consuming to operate.

[0023] The vertical calibration arm 2 includes a shell 21, the top of which is fixedly connected to an electric bolt, and a slot matching the electric bolt is provided in the middle of the upper end of the base plate 1; a calibration slot is provided at one end of the shell 21 close to the slope scale plate 3, and a secondary rotating shaft 22 is rotatably connected to the calibration slot, and a vertical rod 23 is fixedly connected to the secondary rotating shaft 22, and a lead cone head 24 is fixedly connected to the top of the vertical rod 23, and a laser transmitter is installed at the bottom end of the lead cone head 24, and a laser receiver matching the laser transmitter is installed on the inner wall of the calibration slot; a data line matching the laser transmitter is passed through the vertical rod 23, an elastic ring sheath is laid on the surface of the lead cone head 24, and a transparent observation cover is fixed on the calibration slot.

[0024] The front end of the base plate 1 is detachably connected with an auxiliary detection unit 4, and a winding positioning box 5 matching the auxiliary detection unit 4 is fixedly connected to the base plate 1. The auxiliary detection unit 4 includes a base block 41, and a rotating wheel 42 is rotatably connected to the base block 41; an auxiliary fixing nail is inserted between the base block 41 and the rotating wheel 42, and a socket matching the auxiliary fixing nail is opened in the middle of the base block 41 and the rotating wheel 42; An installation cavity is provided in the winding and positioning box 5, and a self-resetting reel 51 is installed in the installation cavity. A through hole communicating with the installation cavity is provided in the middle of the winding and positioning box 5. A traction belt is fixedly connected to the rotating wheel 42, and one end of the traction belt passes through the through hole and is wound around the self-resetting reel 51. A pressure sensing belt is laid on the inner wall of the through hole; the traction belt includes a flexible tape measure, and a distance scale is provided on the flexible tape measure; The through hole is rectangular, and the pressure sensing belts are laid in pairs on the inner walls of the upper and lower ends of the through hole. The pressure sensing belts include a base belt, and a plurality of evenly distributed pressure sensing nodes are arranged on the base belt.

[0025] The installation cavity is provided with a damping disk matching the self-resetting reel 51, an electromagnet is fixedly connected to the side inner wall of the installation cavity, a permanent magnet matching the battery iron is installed on the damping disk, a damping layer is laid on one end of the damping disk close to the self-resetting reel 51, and a self-resetting telescopic rod is connected between the electromagnet and the damping disk.

[0026] The working process of this program is: First, place the device in the space where the slope needs to be measured, ensure that the base plate 1 is in stable contact with the ground, and then start the device. At this time, the stepper motor in the power box 13 works to rotate the main shaft 12, driving the vertical calibration arm 2 and the slope scale plate 3 to rotate together until the laser transmitter on the lead cone head 24 is aligned with the laser receiver, and then stop rotating. At this time, the vertical calibration arm 2 is vertical relative to the horizontal plane. At this time, the operator can observe the slope scale on the slope scale plate 3 corresponding to the upper surface of the C-frame 11, so as to quickly read the slope data; The laser receiver in the calibration slot is used for vertical calibration to ensure the accuracy of the measurement data. The transparent viewing cover allows the operator to observe the calibration status.

[0027] When the auxiliary detection unit 4 is used, it is unfolded by the traction belt and moved along the slope. The distance scale on the traction belt can help measure the horizontal distance; the pressure sensing belt can sense the pressure applied by the traction belt. When the pressure detected is greater than the set value, the surface slope change exceeds the set value. At this time, the device alarms, and then the user fixes the auxiliary detection unit 4, and then moves the substrate 1 to the auxiliary detection unit 4 to merge with it, and then performs slope detection at this position through the vertical calibration arm 2 and the slope scale plate 3; the rotating wheel 42 is rotatable, so that when the auxiliary detection unit 4 is fixed, it is convenient to adjust the substrate 1 to the front and rear sides of the auxiliary detection unit 4 for slope measurement, and then select the fixed positioning point of the substrate 1 according to the slope measurement result, and after the substrate 1 is fixed, move the auxiliary detection unit 4, and perform detection according to the above steps; By using the auxiliary detection unit 4, it is convenient to quickly identify the position where the slope of the continuous slope changes greatly, so as to quickly detect and confirm the different slope sections of the continuous slope; The cooperation between the self-resetting reel 51 and the damping disk ensures the stability and self-resetting function of the traction belt when it is wound; when the electromagnet is turned on, it repels the permanent magnet, causing the damping disk to further pressurize the self-resetting reel 51, thereby ensuring the fixation of the self-resetting reel 51.

[0028] The measurement process of this solution is efficient and accurate, and is suitable for slope planning and measurement in various complex spatial environments.

[0029] Second implementation method: Figure 7 As shown, the slope measuring device also includes an auxiliary detection system, which includes a processor installed on a substrate 1, and a control module, a detection module, a data processing module, a display module and an alarm module are connected to the processor; The control module is used to control the operation of the power box 13 and the electromagnet; it ensures that each device operates according to a predetermined program and logic.

[0030] A detection module is used to collect detection data, including pressure detection data of the pressure sensing belt, whether the laser transmitter and the laser receiver are calibrated, and the rotation angle of the secondary rotating shaft 22. An angle sensor matching the secondary rotating shaft 22 is installed in the housing 21, and the angle sensor is used to detect the rotation angle of the secondary rotating shaft 22; The data processing module is used to analyze and process the detection data; it converts the processed data into slope values, distance values, etc. so that users can understand the measurement results and send them to the display module.

[0031] The display module is associated with the display screen and is used to display the measurement data and results in real time; the user can observe information such as the slope scale, horizontal distance, and alarm information through the display screen.

[0032] The alarm module is used to send out an alarm signal. When it is detected that the slope change exceeds a preset value or an error occurs in the system, the alarm module will send out a sound or alarm message. The alarm module is connected to an audible and visual alarm installed on the substrate 1.

[0033] The auxiliary detection system of this solution ensures the efficiency and accuracy of measurement from controlling the measurement process to displaying the results in real time and then to alarming for abnormal situations.

[0034] In summary, this solution achieves high integration and automation of slope detection, reduces dependence on external equipment and manual operation errors, and the flexibility of the device makes it suitable for various complex spatial environments. It can combine manual detection and automatic detection, is easy to maintain, energy-saving and environmentally friendly, and provides a strong tool support for space planning and measurement.

[0035] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
