Description

Technical Field

[0001] The present invention relates to a light intensity detection device, and particularly to a light intensity detection vehicle based on a cross-arm type. Background Art

[0002] A light intensity detection device is a device used to measure the light intensity or radiation intensity. It can be used to control the brightness and stability of light sources to ensure that the light quality in the production process meets the requirements. It plays an important role and significance in fields such as scientific research, industrial production, and environmental monitoring.

[0003] In the prior art regarding traditional light detection devices, a light illuminance meter automatic detection system is disclosed in the patent document with the publication number CN103630234. It is provided with a mechanical device platform and a motion control system. The detection lamp can move along the guide rail and stop at an appropriate position to detect the light intensity. However, the movement flexibility of this device is extremely low, and it can only move within the range set by the guide rail, which is not suitable for scenarios of large-range light intensity detection. A display screen light intensity detection device with adjustable light source is disclosed in the patent document with the publication number CN 116222974, which can limit the measurement light path and change the field angle size of the measurement light path to provide a variety of different lighting conditions. A ultraviolet light intensity detection device is disclosed in the patent document with the publication number CN 118274959, which can achieve a certain angle of inclination. However, the movable ranges of the above patents are all small, and when it is necessary to measure the light intensity at different positions, the device needs to be manually moved, which brings inconvenience to the measurement process.

[0004] In the prior art regarding light detection vehicles, an airport lighting light intensity detection system is disclosed in the patent document with the publication number CN114486188, including a detection vehicle and a detection board, and the detection board can move with the detection vehicle. This detection vehicle can complete movements on a two-dimensional plane but cannot achieve movements on the Z axis. Summary of the Invention

[0006] To solve the above technical problems, the present invention provides a light intensity detection vehicle based on a cross-arm type, including a detection vehicle body, a cross-arm type lifting module is arranged on the detection vehicle body, and a detection execution module is arranged at the top of the cross-arm type lifting module;

[0007] The cross-arm type lifting module includes a cross driving device and two sets of symmetrically arranged cross-arm groups. Each cross-arm group includes at least two or more levels of cross arms. The adjacent levels of cross arms are respectively the lower-level cross arm and the upper-level cross arm. The lower-level cross arm includes an inner lower-level cross arm and an outer lower-level cross arm. The middle parts of the inner lower-level cross arm and the outer lower-level cross arm are hinged to each other, and a receiving space is provided between the inner lower-level cross arm and the outer lower-level cross arm in the Y-axis direction. The upper-level cross arm is connected above the lower-level cross arm. The upper-level cross arm includes an inner upper-level cross arm and an outer upper-level cross arm. The inner side of the top of the inner lower-level cross arm is hinged to the lower end of the inner upper-level cross arm, and the inner side of the top of the outer lower-level cross arm is hinged to the lower end of the outer upper-level cross arm, so that when the upper-level cross arm is folded, it is arranged in the receiving space of the lower-level cross arm. The middle parts of the inner upper-level cross arm and the outer upper-level cross arm are hinged to each other. The top platform is connected to the topmost upper-level cross arm, and the detection and execution module is arranged on the top platform. The lowermost lower-level cross arm is connected to the cross driving device.

[0008] Preferably, the four end parts of the topmost upper-level cross arm are respectively connected to sliders, and the four sliders are installed on the slide rails of the top platform, so that the top platform slides up or down relative to the two sets of topmost upper-level cross arms.

[0009] Preferably, the length of the topmost upper-level cross arm is greater than the length of the lower-level cross arm.

[0010] Preferably, the length of the upper-level cross arm is greater than the length of the lower-level cross arm.

[0011] Preferably, the cross-sectional width of the lower-level cross arm in the Z-axis direction is wider than the cross-sectional width of the upper-level cross arm in the Z-axis direction. When the lower-level cross arm and the upper-level cross arm are in a cross-folded state, the upper surface of the upper-level cross arm is not higher than the upper surface of the lower-level cross arm.

[0012] Preferably, the middle hole of the lower-level cross arm is arranged at a position slightly lower than the middle in the Z-axis direction.

[0013] Preferably, the connection position between the lower-level cross arm and the upper-level cross arm is arranged at a position slightly higher than the middle of the Z-axis of the lower-level cross arm.

[0014] Preferably, the cross drive device includes two electric push rods symmetrically installed front and back. The electric push rods are respectively fixedly connected to the inner push rod and the outer push rod. The inner push rod is respectively connected to the two lowermost inner lower cross arms of the two groups of symmetrically arranged cross arm groups, and the outer push rod is respectively connected to the two lowermost outer lower cross arms of the two groups of symmetrically arranged cross arm groups. The two electric push rods push or pull with the same magnitude and opposite directions to make the lowermost lower cross arms on both sides move horizontally.

[0015] Preferably, the detection vehicle body includes a vehicle bottom plate. Four servo motors are connected to the four sides of the vehicle bottom plate and fixedly connected to four Mecanum wheels. The four servo motors drive the Mecanum wheels to rotate at a specific speed and drive the detection vehicle body to move forward, backward, left, and right. The cross drive device is symmetrically installed front and back on the vehicle bottom plate.

[0016] Preferably, in the detection execution module, the detection lamp is installed on the top platform through bolts and nuts and rises and falls with the top platform to complete the measurement of the light intensity at different heights.

[0018] 1. The movement of the detection vehicle body is more flexible. After setting a corresponding trajectory for the vehicle, it can be applied to various different light detection scenarios. The added cross-arm type lifting module and the top detection execution module can enable the detection execution module on the platform to detect the change of light intensity with height.

[0019] 2. The cross-arm type lifting module of this light intensity detection vehicle is redesigned, changing the distribution method of the plates at all levels of the common cross arms, increasing the chassis span of the cross-arm type lifting module on the Y-axis, and at the same time reducing the lowest lower limit height when the cross arms at all levels are in the folded state, making the chassis more stable and increasing the lowest detection range of the detection execution module on the Z-axis.

[0020] 3. The device has a simple structure, and the composition and assembly between various components have high modularity and integration, which can provide a useful reference for the design related to light intensity detection.

[0021] 4. While the sensor of the detection execution module of the present invention can move with the vehicle, the multi-level lifting of the sensor is realized, 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.

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

[0028] As Figures 1 to 3 shown, the present invention provides a light intensity detection vehicle based on a cross-arm type, including 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 drive device and two sets of symmetrically arranged cross-arm groups 17. Each cross-arm group 17 includes two-stage cross arms 18. The adjacent-stage cross arms 18 are respectively a lower-stage cross arm 19 and an upper-stage cross arm 20. The lower-stage cross arm 19 includes an inner lower-stage cross arm 23 and an outer lower-stage cross arm 21. Ball bearings 27 are respectively installed in the middle holes of the inner lower-stage cross arm 23 and the outer lower-stage cross arm 21. The two are connected by a lower-stage shaft 22, and a receiving space 30 is provided between the inner lower-stage cross arm 23 and the outer lower-stage cross arm 21 in the Y-axis direction. The upper-stage cross arm 20 is connected above the lower-stage cross arm 19. The upper-stage cross arm 20 includes an inner upper-stage cross arm 24 and an outer upper-stage cross arm 26. A ball bearing 27 is installed in the top hole of the inner lower-stage cross arm 23, and its inner side is fixedly connected to the protruding shaft installed at the lower end of the inner upper-stage cross arm 24. A ball bearing is installed in the top hole of the outer lower-stage cross arm 21, and its inner side is fixedly connected to the protruding shaft installed at the lower end of the outer upper-stage cross arm 26, so that when the upper-stage cross arm 20 is folded, it is installed in the receiving space 30 of the lower-stage cross arm 19. Ball bearings 27 are installed in the middle holes of the inner upper-stage cross arm 24 and the outer upper-stage cross arm 26, and the two are connected by an upper-stage shaft 25. The topmost upper-stage cross arm 20 is connected to the top platform 29. The detection and execution module 3 is arranged on the top platform 29. The detection and execution module 3 includes a detection lamp 31. The lowermost lower-stage cross arm 19 is connected to the cross drive device.

[0030] The detection vehicle body 1 moves more flexibly. After setting a corresponding trajectory for the vehicle, it can be applied to various different light detection scenarios. The added cross-arm type lifting module 2 and the top detection and execution module 3 can enable the detection and execution module of the platform to detect the change of light intensity with height. The cross-arm type lifting module part is redesigned, changing the common stacked distribution method of connecting the outer and inner plates of each stage of the cross arm, and adopting the distribution method of connecting the inner and inner, outer and outer and increasing the chassis span of the cross-arm type lifting module in the Y-axis direction, reducing the lowest lower limit height when each stage of the cross arm is in the folded state, making the chassis more stable, increasing the lowest detection range lower limit of the detection and execution module part in the Z-axis direction, and also being beneficial to increasing the highest detection range upper limit of the detection and execution module part in the Z-axis direction. The device has a simple structure, and the composition and assembly between each component have high modularity and integration, which can provide a useful reference for the design related to light intensity detection. In this embodiment, while realizing that the sensor of the detection and execution module can move with the vehicle, the multi-stage lifting of the sensor is realized, 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 innermost upper cross arm 24 at the top level, which is fixedly connected to the protruding shaft of the slider 28. A ball bearing 27 is installed in the top hole of the outermost upper cross arm 26 at the top level, which is fixedly connected to the protruding shaft of the slider 28. Two symmetrically arranged cross arm groups 17 are connected to the four sliders 28, and the four sliders 28 are installed on the four slide rails of the top platform 29, so that the top platform 29 rises or falls relative to the two upper cross arms 20 at the top level. The length of the upper cross arm 20 at the top level is greater than the length of the lower cross arm 19. This can prevent interference between the slider 28 and the lower cross arm 19 when falling, and at the same time extend the elongation height of the cross arm at the top level 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, which can prevent interference between the upper cross arm 20 at the top level and the slider 28. At the same time, while keeping the number of cross arm levels unchanged, the elongation length is increased at each level to increase the lifting height of the top platform, so that the upper limit of the Z-axis detection range is higher within the same number of cross arm levels.

[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 than 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 than the middle in the Z-axis direction when the lower cross arm 19 is horizontally placed, 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. This can reduce the weight of each level of cross arm, lower the lower limit of the detection on the Z-axis of the top platform 29 and increase the detection range.

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

[0035] The cross drive device is symmetrically installed on the vehicle floor 13 in the front and rear. The cross drive device includes two electric push rods 16 symmetrically installed in the front and rear. The two electric push rods 16 are respectively fixedly connected to the inner push rod 15 and the outer push rod 12. The inner push rod 15 is respectively fixedly connected to the ball bearings 27 in the bottom holes of the two lowermost inner lower cross arms 23 of the two groups of symmetrically arranged cross arm groups 17. The outer push rod 12 is respectively fixedly connected to the ball bearings 27 in the bottom holes of the two lowermost outer lower cross arms 21 of the two groups of symmetrically arranged cross arm groups 17. The two electric push rods 16 push or pull with the same magnitude and opposite directions to move the lowermost lower cross arms 19 on both sides in the horizontal direction. Two electric push rods 16 are installed to drive the movement of the cross arms and the top platform, preventing the position deviation of the top platform during the rising or falling process, ensuring a straight rise, and improving stability. In this embodiment, combined with the cross arm type lifting module 2, the detection lamp 31 can 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 through bolts and nuts and rises and falls with the top platform 29 to complete the measurement of the light intensity at different heights.

[0036] It should be noted that each group of the cross arm groups 17 of the present application is not limited to the two-stage cross arms as described above, and can be set to include multi-stage cross arms up and down, such as four-stage cross arms. Each adjacent stage of cross arms respectively includes a lower cross arm 19 and an upper cross arm 20. The lower cross arms 19 and the upper cross arms 20 of each adjacent stage are structured as the lower cross arm 19 and the upper cross arm 20 of the two-stage cross arm group 17 in Embodiment 1.

[0037] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
