DETAILED DESCRIPTION

[0035] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0036] like Figure 1-12As shown, the present invention provides a photovoltaic micro-porous cast-in-place pile high-efficiency inspection device, comprising a telescopic tube 2, a threaded tube 1 and a sediment detection end 8 which are coaxially arranged in sequence from top to bottom, the sediment detection end 8 is used to detect the sediment thickness in the hole, the telescopic tube 2 is coaxially fixedly connected to one end corresponding to the threaded tube 1, and an indicating scale 5 is slidably sleeved on the surface of the telescopic tube 2;

[0037] The sediment detection end 8 includes a test plate 20 distributed in a coaxial ring. The surfaces of the test plates 20 are respectively provided with second height scales 47 for conveniently reading the sediment thickness data in the hole. The upper ends of the test plates 20 are respectively hinged to the bottom of the threaded tube 1. The upper end of the telescopic tube 2 is fixedly connected to a handle 6. The bottom of the handle 6 is hinged with a handle 29. When the handle 29 swings up and down, a structure is formed in which multiple test plates 20 swing synchronously outward. When in use, the handle 29 on the lower side of the control handle 6 can be controlled to swing up and down to operate the test plates 20 to swing back and forth outward. When multiple test plates 20 swing synchronously outward, the space inside the test plates 20 can be vacated. Then, after the handle 29 is reset, the multiple test plates 20 swing synchronously inward again, which has a clamping effect, so that the user can achieve the purpose of cleaning part of the sediment at the bottom of the hole during the measurement process during the inspection, further improving the device. Functionality: The surface of the threaded tube 1 is threadedly connected with an axially movable roller disk 7, which is used to check the hole diameter, and when in use, the device is placed in the hole through the operating handle 6, and the indicating scale 5 is placed at the hole mouth. When the device is placed, the indicating scale 5 can slide on the surface of the telescopic tube 2, and when the sediment detection end 8 touches the bottom, the hole depth can be obtained by measuring the height of the indicating scale 5 staying on the surface of the telescopic tube 2. After the device is placed in the hole opened in the same row of cast-in-place piles in the same photovoltaic sub-array, the devices in the same row are connected by pulling wires, and the hole position deviation data of the cast-in-place piles in the same row in the same photovoltaic sub-array can be measured. This allows a quality inspector to use one inspection tool to simultaneously complete the inspection of the bored hole diameter, hole position, hole depth, and sediment thickness at the bottom of the hole of the bored piles. Overall, it can reduce the time spent on bored pile hole inspection and improve inspection accuracy and efficiency.

[0038] Furthermore, in order to increase the detectable depth of the device, the telescopic tube 2 is provided with an inner tube 4, a central tube 3 and an outer tube 9 in sequence from the inside to the outside. The inner tube 4, the central tube 3 and the outer tube 9 are respectively socketed to form a telescopic structure of the fishing rod. The length of the telescopic tube 2 can be adjusted by stretching, and the pile length that can be used by the device can be extended in sections. The surfaces of the inner tube 4, the central tube 3 and the outer tube 9 are respectively provided with first height scales 19 with equal distances. During inspection, they are used in conjunction with the indicating scale 5 to facilitate the operator to read the specific hole depth, thereby improving the operator's operating efficiency and detection accuracy during detection.

[0039] Furthermore, the indicating scale 5 is composed of an annular sleeve and a strip ruler fixedly connected to the circumferential surface of the annular sleeve. The annular sleeve is slidably sleeved on the surface of the outer tube 9 and can slide axially on the surface of the outer tube 9. During detection, the hole depth can be obtained by reading the scale located on the lower tube wall and combining it with the scale value of the annular sleeve and the surface of the outer tube 9. The operation is simple, convenient and accurate.

[0040] The roller disc 7 includes an annular plate 10 and a rib plate fixedly connected to the inner side of the annular plate 10 in a cross structure. The middle part of the rib plate is threadedly connected to the threaded tube 1. When the roller disc 7 is rotated, the roller disc 7 can be driven to move axially on the surface of the threaded tube 1 through the threaded connection of the threaded tube 1 in the middle part of the rib plate, so that the height of the roller disc 7 can be adjusted conveniently to ensure the stability and adjustability of the device under different hole depths; the outer side of the rib plate is slidably connected to a test rod 11 that moves radially along the annular plate 10, and the surface of the test rod 11 is respectively provided with a length scale 18, and the outer end of the test rod 11 is divided into A roller 13 is hingedly connected thereto, and an elastic pushing component is connected between the test rod 11 and the rib plate. The elastic pushing component is used to provide a driving force for the roller 13 to move outward. When the device is placed in the hole, the test rod 11 moves inward to press against the elastic pushing component, and the roller 13 is attached to the inner wall surface of the aperture. The aperture can be known by reading the length scale 18 on the surface of the test rod 11, which is convenient for the operator to detect. In addition, the driving force generated by the elastic pushing component can support the device in the center of the hole, which can not only further improve the stability of the device placed in the hole, but also improve the detection result.

[0041] The elastic pushing component includes a pushing spring 15, and the interior of the rib plate is respectively provided with a cylindrical spring groove 17, the pushing spring 15 is placed in the spring groove 17, and the outer ends of the spring groove 17 are respectively provided with sliding holes with the same diameter as the test rod 11, the test rod 11 is slidably connected to the sliding holes, and the inner ends of the test rod 11 are respectively fixedly connected with sliding plates 14 that slidably cooperate with the spring groove 17, the sliding plates 14 are located at the outer ends of the pushing spring 15, and the spring groove 17 is used to provide an installation space for the pushing spring 15 and the test rod 11, and under the action of the sliding plate 14 slidingly connected with the spring groove 17, not only can the stability of the test rod 11 during axial movement be improved, but also the test rod 11 can be prevented from being separated from the spring groove 17, thereby further improving the stability of the device during use.

[0042] The outer ends of the test rod 11 are fixedly connected to the supports 12, and the rollers 13 are rotatably connected to the inner sides of the supports 12. The rolling direction of the rollers 13 is the same as the axial direction of the annular plate 10, and the axial direction of the annular plate 10 is the same as the axial direction of the aperture, so that the device can be placed in the hole for vertical movement, and the rollers 13 can rotate along the aperture, which is convenient for the operator to detect. The inner walls of the spring grooves 17 are respectively provided with a plurality of first limiting grooves distributed in an annular shape along the axial direction of the spring grooves 17, and the circumferential surfaces of the sliding plates 14 are respectively fixedly connected with first limiting protrusions 16 equal in number to the first limiting grooves. When the sliding plate 14 is placed in the spring grooves 17, the first limiting protrusions 16 are slidably connected to the first limiting grooves. Under the action of the sliding connection between the first limiting protrusions 16 and the first limiting grooves, the test rod 11 can only move axially but not rotate, thereby further improving the stability of the rollers 13 when in use.

[0043] The lower end of the threaded tube 1 is fixedly connected to the position corresponding to the test plate 20 with a connecting block 22, and the two ends of the connecting block 22 are fixedly connected to the hinge shaft 24. The upper end of the test plate 20 is respectively provided with a connecting groove 26 on the lower side, and the two sides corresponding to the connecting groove 26 are respectively provided with a mounting groove 25. The inner end of the mounting groove 25 is provided with a hinge hole. The hinge shaft 24 is rotatably connected with the corresponding hinge hole at the upper end of the test plate 20. The surface of the hinge shaft 24 is respectively sleeved with a torsion spring 23, and the torsion spring 23 is respectively located on the inner side of the mounting groove 25. One end of the spring 23 is fixedly connected to the hinge shaft 24, and the other end is fixedly connected to the test plate 20. The torsion spring 23 is used to provide power for the test plate 20 to reset. When the test plate 20 swings outward, the torsion spring 23 is subjected to a torsional force and stores force. After no force is applied to the test plate 20, the torsion spring 23 can reset and drive the test plate 20 to move inward to reset. Under the action of the torsion spring 23, power can be provided for the reset of the test plate 20, which is further converted into a clamping force for the test plate 20 to swing inward to clamp an object, so that the user can clamp the sediment conveniently.

[0044] Furthermore, in order to facilitate the operation of the test plate 20 to swing outward to clamp the sediment, the inner ends of the test plates 20 are respectively hinged with hinged rods 21, and the lower ends of the hinged rods 21 are hinged with a hinge block. The upper end of the hinge block is fixedly connected to a pull rod 27, and the upper end of the pull rod 27 is fixedly connected to a traction rope 28. The other end of the traction rope 28 is connected to a handle 29. When the handle 29 swings upward, it drives the hinge block to move upward, and then pushes multiple test plates 20 to swing outward synchronously through the hinged rod 21 to reserve a clamping space. Then, after the test plate 20 is placed on the sediment surface, the handle 29 is released, and the test plate 20 swings inward and resets under the action of the torsion spring 23, and clamps the sediment for easy removal.

[0045] Furthermore, in order to facilitate the swinging and clamping of sediment by controlling the test plate 20 by operating the handle 29 after adjusting the length of the telescopic tube 2, thereby improving the scope of application and functionality of the device, a mounting box 30 is fixedly connected to the bottom of the handle 29, and a rope pulley 31 is rotatably connected to the inside of the mounting box 30. A wire hole is provided at the lower end of the surface of the mounting box 30, and a through hole 46 is provided at the upper end of the threaded tube 1, the inner tube 4, the center tube 3 and the upper end of the outer tube 9. The end of the traction rope 28 away from the pull rod 27 passes through the through hole 46 and the wire hole to enter the interior of the mounting box 30 and is wound around the surface of the rope pulley 31. The surface is fixedly connected to the rope wheel 31, and a mounting shaft 33 is fixedly connected to the rear end of the rope wheel 31 coaxially, and the mounting shaft 33 is rotatably connected to the rear end of the mounting box 30. A coil spring 32 is arranged on the rear side of the rope wheel 31, and the coil spring 32 is arranged coaxially with the mounting shaft 33. The inner end of the coil spring 32 is fixedly connected to the rope wheel 31, and the outer end of the coil spring 32 is fixedly connected to the inner wall of the mounting box 30. The coil spring 32 is used to drive the rope wheel 31 to rotate, and then drive the rope wheel 31 to reel in the traction rope 28, which has the effect of controlling the length of the traction rope 28 according to the upper end of the telescopic tube 2, so that the traction rope 28 is adapted to the length of the telescopic tube 2; A first end face gear 34 is fixedly connected to the middle of the front end of the rope wheel 31, and a second end face gear 35 is arranged on the front side of the first end face gear 34. A connecting shaft 36 is fixedly connected to the front end of the second end face gear 35. The connecting shaft 36 is axially slidably connected to the front end of the installation box 30. A plurality of annularly distributed stabilizing grooves 45 are axially provided on the surface of the connecting shaft 36. A docking hole is provided on the surface of the installation box 30 corresponding to the connecting shaft 36. The connecting shaft 36 is slidably connected to the inner side of the docking hole. A plurality of annularly distributed stabilizing protrusions 44 are fixedly connected to the inner wall of the docking hole. The stabilizing protrusions 44 and the stabilizing protrusions 44 are axially connected to the stabilizing protrusions 45. The groove 45 is slidably fitted so that the connecting shaft 36 can only move axially but cannot rotate. Then, when the second end face gear 35 is meshed with the first end face gear 34, the rope pulley 31 cannot rotate, and the length of the traction rope 28 is fixed. Then, by swinging the control handle 29, multiple test plates 20 can be driven to swing outward under the traction of the traction rope 28. An operating panel 42 is connected to the front end of the connecting shaft 36. The operating panel 42 is used to facilitate the control of the meshing and separation of the first end face gear 34 and the second end face gear 35, so that the operator can control the length of the traction rope 28 according to the length of the telescopic tube 2, which is convenient for operation.

[0046] Furthermore, in order to facilitate the operator to control the meshing and separation of the first end face gear 34 and the second end face gear 35, an annular support seat 38 is provided at the front end of the installation box 30, and the support seat 38 is coaxially arranged with the connecting shaft 36. A meshing groove 39 is provided on the front end surface of the support seat 38, and a mounting plate 40 is fixedly connected to the rear end of the operating plate 42, and a meshing block 41 meshing with the meshing groove 39 is fixedly connected to the rear end of the mounting plate 40. A return spring 37 is sleeved on the surface of the connecting shaft 36 located inside the installation box 30, and the return spring 37 is used to promote the meshing of the first end face gear 34 and the second end face gear 35. When the meshing block 41 meshes with the meshing groove 39, the support seat 38 fits with the mounting plate 40, and the second end face gear 35 meshes with the first end face gear 34 under the push of the return spring 37, thereby forming an effect of fixing the rope wheel 31;

[0047] The two side surfaces of the engagement block 41 are inclined inwardly, and the engagement groove 39 is engaged with the engagement block 41. In the specific implementation, since the front end of the connecting shaft 36 is connected to the operating plate 42, the operating plate 42 and the connecting shaft 36 can maintain a transmission relationship. Figure 8 , Fig.10 and Fig.11 As shown in the figure, the two side surfaces on the inner side of the meshing groove 39 meshing with the meshing block 41 are also inclined structures inclined inwardly. Since the mounting plate 40 is fixedly connected to the operating plate 42, and the meshing block 41 is fixedly connected to the mounting plate 40, when the operating plate 42 rotates, the mounting plate 40 can be driven to rotate, and then when the mounting plate 40 rotates, the meshing block 41 is driven to move. When the meshing block 41 moves, the inclined surface structures on the inner side of the meshing groove 39 are pushed by the inclined surface structures on both sides of the meshing block 41, and the generated reverse thrust can drive the operating plate 42 and the mounting plate 40 to rotate. The operation plate 42 is connected to the connecting shaft 36, and the connecting shaft 36 can be driven to axially displace after the operation plate 42 is axially displaced, and the second end face gear 35 is driven to disengage from the first end face gear 34 under the transmission of the connecting shaft 36, so that the meshing block 41 can be disengaged from the meshing groove 39 by rotating the operation plate 42, and the second end face gear 35 is driven to disengage from the first end face gear 34 under the action of the connecting shaft 36, so that the rope wheel 31 resumes rotation, and the length of the traction rope 28 can be adjusted conveniently;

[0048] Furthermore, in order to facilitate the rope pulley 31 to wind the traction rope 28 and prevent the traction rope 28 from escaping from the rope pulley 31, a winding groove is opened on the surface of the rope pulley 31, and the inner walls of the winding groove are respectively inclined surfaces 43 inclined inwardly, so that the bearing range of the outer opening of the winding groove is maximized, and the traction rope 28 can be wound over a large range, which can prevent the traction rope 28 from derailing, and the traction rope 28 is concentratedly wound on the inner side of the rope pulley 31, thereby improving the winding effect, further improving the stability when adjusting the traction rope 28, and facilitating the operator to use.

[0049] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways.
