Description

Technical Field

[0001] The present invention relates to the technical field of road detection, and in particular to a road detection device in a photovoltaic field. Background Art

[0002] Photovoltaic sites are areas where solar photovoltaic power generation equipment is centrally installed to convert solar energy into electricity. New roads within these sites should undergo regular inspections during construction in accordance with relevant specifications and standards. Generally, after each completed layer of roadbed or pavement, appropriate inspections, such as those for compaction and smoothness, are conducted to ensure that construction quality meets requirements. Upon completion, a comprehensive acceptance inspection, encompassing all inspection items, should be conducted to assess whether the road meets design and operational requirements.

[0003] The patent document with announcement number CN114812489B proposes a road surface flatness detection device. When encountering a raised road surface, the wear-resistant steel ball is squeezed, causing the telescopic spring to further compress, driving the connecting rod, recording pen and wear-resistant steel ball to move upward. The upward movement of the wear-resistant steel ball causes the opening of the lower end face of the marking tube to no longer be blocked, and the colored liquid flows out and is brushed on the raised road surface, thereby marking the raised road surface.

[0004] However, in the above-mentioned road surface flatness detection device, there are gaps between the multiple wear-resistant steel balls, and there are roads that are not contacted by the wear-resistant steel balls. If there are bulges or depressions at that location, the wear-resistant steel balls do not contact that location and cannot be marked, resulting in incomplete detection data. Summary of the Invention

The connecting rod passes through the central opening of the hollow turntable, and a channel is opened inside the marking cylinder. A sealing plug for blocking the channel is fixedly installed at the bottom of the connecting rod, and an opening is opened in the middle of the sealing plug.

The convex position will be marked by two straight lines. The spiral sheets are stretched to cover the road horizontally, avoiding incomplete detection data.

[0020] Furthermore, the transverse slope of the road in the left and right directions is usually controlled within a certain range. When the transverse slope of the road exceeds the specified range and the heights of the two edge strips are different, the support frame generates an inclination angle, and the inclination direction of the lower connecting rotating block in the middle changes. The lower connecting rotating block uses the upward rod to drive the extrusion slider to move, and the extrusion slider is displaced and the pressure ring is used to squeeze the ink-absorbing air bag, thereby squeezing the ink in the ink-absorbing air bag from the nozzle. After the ink is sprayed out, a transverse mark is left on the road to detect the transverse slope.

[0021] Furthermore, the scraper is positioned by engaging the card slot and the elastic card block, and the scraper is used to process the mud blocks on the road to prevent the mud blocks from affecting road detection. At the same time, when the scraper contacts the raised cement blocks on the road, the thrust applied to the scraper is greater than the resistance of the card slot and the elastic card block, so the scraper rotates to avoid the cement blocks to avoid affecting the progress of the inspection vehicle.

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention.

[0034] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0037] Example 1: This example proposes a road detection device for a photovoltaic field, such as Figure 1 As shown, it includes an inspection vehicle 1, the bottom of which is rotatably connected to an inspection wheel 2, an ink tank 3 is fixedly installed on the top of the inspection vehicle 1, a motor for driving the inspection wheel 2 is fixedly installed on the top of the inspection vehicle 1, and the ink tank 3 is filled with washable marking ink.

[0038] like Figure 2 and Figure 4 As shown, a detection mechanism 4 is provided at the bottom of the detection vehicle 1, and the detection mechanism 4 includes a support frame 41. The support frame 41 adopts an I-shaped structure. The front and rear sides of the support frame 41 are rotatably connected to the detection vehicle 1. The internal rotation of the support frame 41 is connected to a screw rod 42. The threads on the screw rod 42 are symmetrically arranged. The screw rod 42 is threadedly connected to two symmetrically arranged screw sleeve blocks 43. Guide splints 44 are fixedly installed at both ends of the screw sleeve blocks 43.

[0039] like Figure 3 As shown, a folding frame 45 is fixedly installed in the I-shaped opening of the support frame 41, and an edge strip 46 is fixedly installed at the other end of the folding frame 45. The screw 42 rotates and drives the upper screw sleeve blocks 43 to move toward each other, and the two screw sleeve blocks 43 clamp the folding frame 45 so that the folding frame 45 can be unfolded left and right.

[0040] like Figure 5 and Figure 6 As shown, a plurality of equally spaced marking cylinders 47 are fixedly mounted on the bottom of the folding frame 45 , and adjacent marking cylinders 47 are rotatably connected to opposite sides with hollow turntables 49 , and a spiral piece 48 is fixedly mounted between the two hollow turntables 49 .

[0041] When the folding frame 45 is unfolded, the multiple marking cylinders 47 at its bottom are unfolded, and the distance between adjacent marking cylinders 47 is the same. The marking cylinders 47 support the spiral blades 48 through the hollow rotating disk 49. The spiral blades 48 and the hollow rotating disk 49 roll along the ground. When the ground is flat, the bottoms of the spiral blades 48 are flush. When the ground is uneven, the spiral blades 48 are affected by the ground and bend. The unfolding of the folding frame 45 causes the multiple marking cylinders 47 to unfold and stretch the spiral blades 48, so that the spiral blades 48 cover the road horizontally. Because the road bumps have a certain range of undulations, rather than protruding at a single point, but rather in a wavy pattern, the spiral blades 48 can fully detect the location of the bumps on the road during its rolling.

[0042] A supporting telescopic rod 410 passing through the center of the hollow turntable 49 is fixedly installed between the two marking cylinders 47. A telescopic gasket 411 in contact with the spiral piece 48 is connected to the inside of the supporting telescopic rod 410 for sliding up and down. The bottom of the spiral piece 48 is in contact with the ground. A marking component is provided between the marking cylinder 47 and the telescopic gasket 411. The marking component includes a connecting rod 412. The connecting rod 412 adopts an L-shaped structure. The bottom of the connecting rod 412 is fixedly connected to the telescopic gasket 411. The connecting rod 412 slides up and down inside the supporting telescopic rod 410. The connecting rod 412 passes through the central opening of the hollow turntable 49. A channel is provided inside the marking cylinder 47. A sealing plug 413 for blocking the channel is fixedly installed at the bottom of the connecting rod 412. An opening is provided in the middle of the sealing plug 413. When the opening is connected to the channel, the marking cylinder 47 is connected up and down. A folding frame 45 is fixedly installed in the I-shaped opening of the support frame 41. The marking cylinder 47 is connected to the ink tank 3.

[0043] When the bottom of the spiral piece 48 bends, the spiral piece 48 lifts up the telescopic gasket 411, and the telescopic gasket 411 drives the connecting rod 412 and the sealing plug 413 to move upward. At this time, the channel inside the marking cylinder 47 is opened, and the marking ink inside the ink tank 3 flows out from the ball at the bottom of the marking cylinder 47 and is painted by the ball to form a straight line along the direction of the road.

[0044] In this embodiment, the folding frame 45 is unfolded to unfold multiple marking cylinders 47 and stretch the spiral sheet 48. After being stretched, the spiral sheet 48 covers the road horizontally. When the road is raised, the spiral sheet 48 bends and pushes the telescopic gasket 411 upward, so that the sealing plug 413 moves upward and the marking cylinder 47 is connected up and down, so that the marking ink flows out and is painted by the ball to draw a straight line along the direction of the road. The raised position will be marked by two straight lines, and the spiral sheet 48 is stretched to cover the road horizontally to avoid incomplete detection data.

[0045] Example 2, based on Example 1, this example proposes a road detection device for a photovoltaic field, such as Figure 2 and Figure 7 As shown, a deflection mechanism 5 for detecting inclination is fixedly installed on the top of the support frame 41, and the deflection mechanism 5 includes a lower connecting block 51. The bottom of the lower connecting block 51 is fixedly connected to the support frame 41. An opening for the rotation of the lower connecting block 51 is opened on the top of the detection vehicle 1. Two symmetrically arranged upward rods 52 are fixedly installed on the top of the lower connecting block 51. Support plates are fixedly installed on the left and right sides of the detection vehicle 1. A sliding column is fixedly installed between the two support plates. An extrusion slider 55 is slidably connected to the sliding column. Buffer springs 56 are fixedly connected to both ends of the extrusion slider 55, and a pressure ring 57 is fixedly installed on the end of the buffer spring 56.

[0046] By using the upper rod 52 as an extension of the lower connecting rotating block 51, the horizontal slope of the road in the left and right directions is usually controlled within a certain range. When the heights of the two edge strips 46 are different, the support frame 41 produces an inclination angle, and the inclination direction of the lower connecting rotating block 51 in the middle changes. When the rotation angle is small, the upper rod 52 rotates its end to produce displacement. The longer the length of the upper rod 52, the longer the distance its end moves.

[0047] A slide frame 54 is fixedly mounted on the top of the extrusion slide block 55, and a cylinder 53 is fixedly mounted between the two upward rods 52. The cylinder 53 slides up and down in the slide frame 54. The slide frame 54 and the cylinder 53 cooperate to prevent the slide frame 54 and the upward rod 52 from getting stuck to each other.

[0048] An ink-absorbing air bag 58 mounted on a sliding column is fixedly installed on the side of the support plate. The ink-absorbing air bag 58 is located on the sliding path of the extrusion slider 55. Washable ink is injected into the ink-absorbing air bag 58. A nozzle 59 that penetrates the support plate is fixedly installed at one end of the ink-absorbing air bag 58. When the transverse slope of the road exceeds a certain angle, the lower connecting block 51 and the upward rod 52 drive the slide frame 54 and the extrusion slider 55 to move. The extrusion slider 55 is displaced and uses the pressure ring 57 to squeeze the ink-absorbing air bag 58, thereby squeezing the ink in the ink-absorbing air bag 58 from the nozzle 59.

[0049] In this embodiment, the transverse slope of the road in the left and right directions is usually controlled within a certain range. When the transverse slope of the road exceeds the specified range and the heights of the two edge strips 46 are different, the support frame 41 generates an inclination angle, and the inclination direction of the lower connecting rotating block 51 in the middle changes. The lower connecting rotating block 51 uses the upward rod 52 to drive the extrusion slider 55 to move. The extrusion slider 55 is displaced and uses the pressure ring 57 to squeeze the ink-absorbing air bag 58, thereby squeezing the ink in the ink-absorbing air bag 58 from the nozzle 59. After the ink is sprayed out, a transverse mark is left on the road to detect the transverse slope.

[0050] Example 3, based on the above-mentioned Example 1 or Example 2, this embodiment proposes a road detection device for a photovoltaic field, such as Figure 8 and Figure 9As shown, a cleaning mechanism 6 is provided on the front and rear sides of the support frame 41, and the cleaning mechanism 6 includes a telescopic frame 61, which is divided into multiple sections. A brush 62 is fixedly installed at the bottom of each section of the telescopic frame 61, and a scraper 63 is rotatably connected to the bottom of each section of the telescopic frame 61. A torque spring 64 is elastically connected between the rotating shaft of the scraper 63 and the telescopic frame 61, and the bottom height of the scraper 63 is flush with the brush 62.

[0051] The edge strip 46 is supported and guided by the telescopic frame 61 , the brush 62 at the bottom of the telescopic frame 61 cleans the stones on the road, and the scraper 63 processes the mud on the road.

[0052] A slot 65 is defined in the middle of the scraper 63, and an elastic block 66 is fixedly mounted inside the telescopic frame 61, engaging with the slot 65. The slot 65 and the elastic block 66 engage to position the scraper 63. When the scraper 63 contacts a raised cement block on the road, the thrust applied to the scraper 63 is greater than the resistance of the slot 65 and the elastic block 66, causing the scraper 63 to rotate to avoid the cement block.

[0053] In this embodiment, the scraper 63 is positioned by engaging the slot 65 and the elastic block 66, and the scraper 63 is used to process mud blocks on the road to prevent the mud blocks from affecting road detection. At the same time, when the scraper 63 contacts the raised cement blocks on the road, the thrust applied to the scraper 63 is greater than the resistance of the slot 65 and the elastic block 66, so the scraper 63 rotates to avoid the cement blocks to avoid affecting the movement of the detection vehicle 1.

[0054] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
