[0027] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0028] like Figures 1 to 3 As shown, the present invention provides a cross-arm-based light intensity detection vehicle, comprising a detection vehicle body 1, a cross-arm-type lifting module 2 is arranged on the detection vehicle body 1, and a detection execution module 3 is arranged on the top of the cross-arm-type lifting module 2;

[0029] The cross-arm type lifting module 2 includes a cross-driving device and two groups of symmetrically arranged cross-arm groups 17, each group of the cross-arm groups 17 includes two levels of cross arms 18, and the cross arms 18 of adjacent levels are respectively a lower cross arm 19 and an upper cross arm 20, the lower cross arm 19 includes an inner lower cross arm 23 and an outer lower cross arm 21, ball bearings 27 are respectively installed in the middle holes of the inner lower cross arm 23 and the outer lower cross arm 21, the two are connected by a lower shaft 22, and an accommodating space 30 is set between the inner lower cross arm 23 and the outer lower cross arm 21 in the Y-axis direction, the upper cross arm 20 is connected above the lower cross arm 19, the upper cross arm 20 includes an inner upper cross arm 24 and an outer upper cross arm 26, the inner lower cross arm 23 and the outer lower cross arm 21 are respectively installed in the middle holes of the ball bearings 27, the two are connected by a lower shaft 22, and an accommodating space 30 is set between the inner lower cross arm 23 and the outer lower cross arm 21 in the Y-axis direction, the upper cross arm 20 is connected above the lower cross arm 19, the upper cross arm 20 includes an inner upper cross arm 24 and an outer upper cross arm 26, A ball bearing 27 is installed in the top hole of the upper cross arm 23, and its inner side is fixedly connected to the protruding shaft installed at the lower end of the inner upper cross arm 24. A ball bearing is installed in the top hole of the outer lower cross arm 21, and its inner side is fixedly connected to the protruding shaft installed at the lower end of the outer upper cross arm 26, so that the upper cross arm 20 is installed in the accommodating space 30 of the lower cross arm 19 when folded. A ball bearing 27 is installed in the middle hole of the inner upper cross arm 24 and the outer upper cross arm 26, and the two are connected by the upper shaft 25. The uppermost upper cross arm 20 is connected to the top platform 29, and the detection execution module 3 is arranged on the top platform 29. The detection execution module 3 includes a detection light 31. The lowermost lower cross arm 19 is connected to the cross driving device.

[0030] The detection vehicle body 1 is more flexible in movement. After setting the corresponding trajectory for the vehicle, it can be applied to various different light detection scenes. The added cross-arm lifting module 2 and the top detection execution module 3 can enable the detection execution module of the platform to detect the change of light intensity with height. The cross-arm lifting module part is redesigned, and the common stacking distribution mode of the cross-arm plates at each level is changed. The distribution mode of connecting the inside and the outside to each level and increasing the chassis span of the cross-arm lifting module on the Y axis is adopted, and the lowest lower limit height of each level of the cross-arm in the folded state is reduced, making the chassis more stable, increasing the lowest detection range lower limit of the detection execution module part on the Z axis, and also helping to improve the highest detection range upper limit of the detection execution module part on the Z axis. The device has a simple structure, and the composition and assembly between the various components have high modularity and integration, which can provide a useful reference for the design related to light intensity detection. While realizing that the sensor of the detection execution module can move with the vehicle, this embodiment realizes the multi-level lifting of the sensor, taking into account the flexibility of the horizontal and vertical position movement of the sensor, making the light intensity measurement work more flexible and convenient.

[0031] In other specific embodiments, a ball bearing 27 is installed in the top hole of the inner upper cross arm 24 at the top, which is fixedly connected to the protruding shaft of the slider 28; a ball bearing 27 is installed in the top hole of the outer upper cross arm 26 at the top, which is fixedly connected to the protruding shaft of the slider 28; two groups of symmetrically arranged cross arm groups 17 are connected to four sliders 27, and the four sliders 27 are installed on four slide rails of the top platform 29, so that the top platform 29 can be raised or lowered relative to the two groups of upper cross arms 20 at the top. The length of the upper cross arm 20 at the top is greater than that of the lower cross arm 19. This avoids interference between the slider 27 and the lower cross arm 19 when falling, and at the same time, the cross arm is extended at the top to increase the lifting height of the top platform.

[0032] In other specific embodiments, the length of the upper cross arm 20 can be set to be greater than the length of the lower cross arm 19 to avoid interference between the uppermost upper cross arm 20 and the slider 28. At the same time, each level increases the extension length while keeping the number of cross arms unchanged, thereby increasing the lifting height of the top platform and making the upper limit of the Z-axis detection range higher within the same number of cross arms.

[0033] In other specific embodiments, the cross-sectional width of the lower cross arm 19 in the Z-axis direction is wider than the cross-sectional width of the upper cross arm 20 in the Z-axis direction, the middle hole of the lower cross arm 19 is arranged at a position slightly lower in the middle in the Z-axis direction, and the connection position between the lower cross arm 19 and the upper cross arm 20 is arranged at a position slightly higher in the middle in the Z-axis direction when the lower cross arm 19 is placed horizontally, so that when the lower cross arm 19 and the upper cross arm 20 are in a cross-folded state, the upper surface of the upper cross arm 20 is not higher than the upper surface of the lower cross arm 19. Reduce the weight of each level of cross arms, reduce the detection lower limit of the top platform 29 in the Z-axis, and increase the detection range.

[0034] In other specific embodiments, the detection vehicle body 1 includes a vehicle bottom plate 13, and the vehicle bottom plate 13 is designed with mounting holes around it for mounting and fixing the four servo motors 14, and the two are fixedly connected by bolts, and the servo motors 14 are fixedly connected to the Mecanum wheels 11 through D-shaped holes; when the host computer transmits instructions to the four servo motors 14 on the wheel side, the servo motors 14 can drive the corresponding Mecanum wheels 11 to move to a specified position, completing the fixed-point detection of the light intensity at a certain position in the plane. The entire detection platform of this embodiment is mounted on a trolley, which is equipped with Mecanum wheels and can move freely forward, backward, left, and right, and is very flexible.

[0035] The cross drive device is symmetrically installed on the vehicle bottom plate 13. The cross drive device includes two electric push rods 16 symmetrically installed in front and back, and the two electric push rods 16 are fixedly connected to the inner push rod 15 and the outer push rod 12 respectively. The inner push rod 15 is fixedly connected to the ball bearings 27 in the bottom holes of the two lowest inner lower cross arms 24 of the two groups of symmetrically arranged cross arm groups 17, and the outer push rod 12 is fixedly connected to the ball bearings 27 in the bottom holes of the two lowest outer lower cross arms 21 of the two groups of symmetrically arranged cross arm groups 17; the two electric push rods 16 push or stretch the lower cross arms 19 at the lowest level on both sides in the horizontal direction with the same size and opposite direction. Two electric push rods 16 are installed to drive the movement of the cross arm and the top platform to prevent the top platform from being offset during the lifting or lowering process, ensure straight rise, and improve stability. This embodiment is combined with the cross arm lifting module 2 to enable the detection light 31 to move to any point in the detection space. In the detection execution module 3, the detection lamp 31 is installed on the top platform 29 by means of bolts and nuts, and rises and falls with the top platform 29 to complete the measurement of light intensity at different heights.

[0036] It should be noted that each group of the cross-arm group 17 in the present application is not limited to the two-level cross-arm as described above, and can be set to include multiple levels of cross-arms, such as four-level cross-arms, and the cross-arms of each adjacent level respectively include a lower-level cross-arm 19 and an upper-level cross-arm 20, and the lower-level cross-arm 19 and the upper-level cross-arm 20 of each adjacent level are the structural settings of the lower-level cross-arm 19 and the upper-level cross-arm 20 of the two-level cross-arm group 17 in Example 1.
