DETAILED DESCRIPTION

[0029] Embodiment 1, as Figure 1-Figure 3 As shown, a slope measuring device for land space planning proposed by the present invention comprises a measuring box 1, two groups of light positioning components 4, two groups of slope measuring components 3 and an auxiliary component 5; a moving wheel 2 is arranged at the bottom of the measuring box 1, a push handle 6 is arranged at the rear side, and a data processing controller is arranged inside; the two groups of light positioning components 4 are respectively arranged on both sides of the measuring box, with the light positioning surface facing downward and always kept perpendicular to the horizontal plane; the two groups of slope measuring components 3 are respectively arranged on both sides of the measuring box and correspond one by one to the bottom of the light positioning components 4, each group of slope measuring components 3 is a triangular structure, and the top corner emits measuring light to the light positioning surface, and then receives the reflected light after positioning the light angle to obtain slope change data, and the two groups of corners at the bottom move in contact with the ground to obtain the slope change trend; the auxiliary component 5 is located at the front side of the measuring box 1, on the one hand, the actual walking light and the predetermined guide light are emitted through the route auxiliary component 501 to guide the two groups of light to overlap to confirm the measurement route, and on the other hand, the ground is trimmed through the road surface clearing component 502 to remove roadblocks.

[0030] like Figure 4 As shown, the distance between the two groups of slope measuring components 3 is adjustable. When encountering a roadblock or setting a measurement position, the distance between the two groups of slope measuring components 3 can be adjusted according to demand. In a specific implementation, a double-headed bidirectional cylinder 301 can be set to penetrate the measuring box 1, and the telescopic rod end extends out of the measuring box 1 to connect the installation points of the slope measuring components 3 on both sides.

[0031] The slope measurement assembly 3 includes a mounting plate 302; the mounting plate 302 is mounted on the telescopic rod of the double-headed bidirectional cylinder 301, a laser tracker 306 for emitting and receiving measuring light is arranged on the top, and a front and rear mounting rod 303 are arranged on the bottom to form a three-piece structure; a measuring wheel 304 is arranged at the bottom of the mounting rod 303, and a support member 305 located outside the measuring wheel 304 is also arranged.

[0032] It should be further explained that the bottoms of the moving wheel 2 and the measuring wheel 304 are on the same horizontal plane, and the moving wheel 2 is located at the center of the four groups of measuring wheels 304 and moves at five points.

[0033] When measuring the slope, the measuring wheel 304 and the moving wheel 2 move along the ground. When encountering a sloped ground, the front and rear measuring wheels 304 form an up-and-down position difference, and the laser tracker 306 rotates relative to the light positioning surface. The slope data can be obtained by recording the trajectory of the light changes.

[0034] like Figure 5 As shown, the light positioning assembly 4 includes a light positioning plate 401 movably mounted above the mounting plate 302 via a hanging rod 402, the light positioning surface of which is always vertically downward due to its own weight, and is provided with a plurality of groups of laser sensors.

[0035] Since the light positioning surface is always vertically downward, and the laser tracker 306 rotates with the mounting plate 302 when the slope changes, the laser tracker 306 and the light positioning surface rotate relative to each other. When the ground is level, the laser tracker 306 emits light to the center line of the light positioning surface, and the emitted light is sensed by the laser sensor at the corresponding position, and the slope at this time is recorded as 0°. When going uphill, the measuring wheel 304 forms an up-and-down position difference, the laser tracker 306 rotates, and the emitted light is sensed by the laser sensor at the corresponding position. The slope change is analyzed by sensing the position change of the front and rear laser sensors and recorded as a°. The validity of the data is determined by emitting and receiving light. The same is true for going downhill, and it is recorded as -a°.

[0036] It should be further explained that the light positioning plate 401 is an arc-shaped plate, and the laser sensors are arranged in a matrix along its concave surface, that is, the light positioning surface; the spirit level 403 is arranged in the middle of the arc-shaped plate; the balance adjustment parts are arranged at both ends of the arc-shaped plate, and the heights of the two ends of the light positioning plate 401 are adjusted by respectively inflating and deflating air, so that the spirit level 403 always displays horizontality to maintain the light positioning surface always vertically downward.

[0037] It should be further explained that the balance adjustment part includes an air bag column 404 located at the end of the light positioning plate 401; an air pump 405 for inflating and deflating air is arranged on the air bag column 404; the air pump 405 is activated when the level meter 403 monitors that the horizontality does not meet the standard, and the height and balance of the two ends of the light positioning plate 401 are adjusted by inflating or deflating the air bag columns 404 at both ends, so as to finally maintain the light positioning surface always vertically downward, so as to ensure the accuracy and intelligence of the slope test results.

[0038] like Figure 6 As shown, the support member 305 includes a double-headed rotating driving member 30501 and a mounting frame 30502 located on the driving end of the double-headed rotating driving member 30501; a support rod 30504 that slides up and down is arranged on the mounting frame 30502; two groups of support rods 30504 extend to both sides of the measuring wheel 304 respectively, and an upper limit seat is arranged at the top end, a lower limit seat 30505 is arranged at the lower end, and a support wheel 30506 is arranged at the bottom end; a spring 30503 is sleeved on the support rod 30504 and is located between the mounting frame 30502 and the lower limit seat 30505, pushing the support wheel 30506 to fit the ground; a vertical groove is arranged on the support rod 30504, and a row of in-position transmitting sensors 30507 is arranged in the groove; an in-position receiving sensor 30508 corresponding to the position of the groove is arranged on the mounting frame 30502.

[0039] The double-headed rotating drive member 30501 can be a combination structure of two groups of motors, which drives the mounting frame 30502 to rotate according to the change in slope, so that the support wheel 30506 is always facing the ground. The support wheel 30506 is pulled by the spring 1 30503 to always fit the ground, ensuring its support effect under different slopes. Auxiliary support is provided for the movement of the measuring wheel 304; when the ground is uneven, one side of the measuring wheel 304 on the front and rear sides may be suspended, resulting in errors in the measurement results. Through the cooperation of the in-place transmitting sensor 30507 and the in-place receiving sensor 30508, the lifting distance of the support wheel 30506 is recorded, and the unevenness of the ground is obtained to correct the slope data.

[0040] like Figure 7 As shown, the auxiliary component 5 includes an auxiliary frame 503 which is driven by a translation cylinder 505 and can be retracted in front of the measuring box 1; a mounting slot with a bottom opening is arranged in the auxiliary frame 503 for the road surface clearing member 502 to enter and exit, a route auxiliary member 501 is installed on the top, and a roadblock monitor 504 is installed at the front. The roadblock monitor 504 uses infrared radiation for non-contact measurement and activates the road surface clearing member 502 when a roadblock is detected.

[0041] like Figure 8As shown, the road surface clearing member 502 includes a lead screw 50203 driven by a motor and rotating in a mounting groove; the clearing frame 50201 is threadedly connected to the lead screw 50203 and is raised and lowered in the mounting groove, and teeth 50202 for entering and exiting the opening are provided at the bottom; the teeth 50202 enter and exit the opening to adjust the distance from the ground, and then the pits can be filled and the protrusions can be removed in advance before measuring the slope, so as to achieve the purpose of trimming the ground and reduce measurement errors.

[0042] like Fig. 9 As shown, the route auxiliary component 501 includes an actual walking light emitter 50101 fixed on an auxiliary frame 503, and its light source 1 50104 emits a fixed laser to indicate the actual walking route; the predetermined guide light emitter 50102 is rotatably set on the actual walking light emitter 50101, and its light source 2 50103 emits a movable laser to indicate the predetermined guide route. When using the equipment, the staff needs to maintain the overlap of the light source 1 50104 and the light source 2 50103, thereby ensuring the fixation of the route during measurement and reducing the measurement error. Especially at night when the light is not good, the accuracy of the measurement can be maintained.

[0043] like Figure 10-11 As shown, a fixing assembly 7 is also arranged at the rear side of the measuring box 1; the fixing assembly 7 comprises a fixing seat 701 fixed on the measuring box 1; a through hole 708 and a clamping block 704 are arranged on the fixing seat 701; a lifting plate 702 is slidably arranged above the fixing seat 701 through a slider 709, and a rotatable pedal 703 is arranged at the front side; a clamping groove 705 matching the clamping block 704 is arranged on the pedal 703; a plug rod 706 is arranged at the bottom of the lifting plate 702 and corresponds to the position of the through hole 708; a second spring is sleeved on the plug rod 706 and is located between the fixing seat 701 and the lifting plate 702; when the device needs to be fixed, the pedal 703 is turned over. By stepping on the pedal 703, the lifting plate 702 and the plug rod 706 are driven to descend. The plug rod 706 passes through the through hole 708 and is stuck in the ground. The pedal 703 is turned downward, the clamping block 704 is stuck in the clamping groove 705, and the plug rod 706 is fixed, so that the device can be parked on the slope.

[0044] Embodiment 2: Based on the slope measurement device for land space planning in embodiment 1, this embodiment proposes a slope measurement method for land space planning, and the steps are as follows:

[0045] S1, flip the pedal 703 upwards, so that the block 704 and the slot 705 are separated, and the lifting plate 702 and the plug rod 706 rise under the push of the spring 2, and the device can move;

[0046] S2. The staff moves the device to a horizontal plane, and adjusts the balance of the two ends of the light positioning plate 401 by inflating or deflating the airbag columns 404 at both ends. The laser tracker 306 emits light to the center line of the light positioning surface. The emitted light is sensed by the laser sensor at the corresponding position, and the slope is recorded as 0° at this time.

[0047] S3. The staff maintains the overlap of the light source 1 50104 and the light source 2 50103, and moves the device along the set route on the ground to be measured; when moving, the teeth 50202 enter and exit the opening to adjust the distance from the ground, and then fill the pits and remove the protrusions in advance before measuring the slope;

[0048] S4, when going uphill, the measuring wheel 304 forms an up-down position difference, the laser tracker 306 rotates, and the emitted light is sensed by the laser sensor at the corresponding position. The slope change is analyzed by sensing the position change of the front and rear laser sensors and recorded as a°;

[0049] S5. When the ground is uneven, the in-place transmitting sensor 30507 and the in-place receiving sensor 30508 cooperate to record the lifting distance of the support wheel 30506, obtain the unevenness of the ground, and correct the slope data;

[0050] S6. The data processing controller analyzes the slope data collected along the way to obtain the slope change data of the entire road section and each point for use in national land space planning.

[0051] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
