Description
Technical Field
[0001] This utility model relates to the field of photovoltaic grouting pile technology, and in particular to a photovoltaic grouting pile quality inspection and mud cleaning device. Background Technology
[0002] Photovoltaic cast-in-place piles are a common type of pile foundation structure in photovoltaic power station foundation engineering. They are mainly used to fix photovoltaic modules to the ground, providing stable support for the entire photovoltaic system, resisting external forces such as wind loads and snow loads, and ensuring the long-term safe operation of the photovoltaic array. In the construction of photovoltaic power stations, the drilling quality of photovoltaic cast-in-place piles as a foundation structure, such as hole diameter, hole depth and bottom cleanliness, directly affects the bearing capacity of the pile body.
[0003] After drilling existing photovoltaic cast-in-place piles, a special device is needed to clean the bottom mud and test the drilling parameters. The mud cleaning spoon is the core component for cleaning the mud. The existing mud cleaning spoons are mostly connected to the main structure by welding or multiple sets of bolts. After the mud cleaning spoon is worn, it cannot be replaced individually. The entire device needs to be replaced, which is costly to maintain. Disassembly and assembly require tightening each bolt one by one, which is cumbersome. In muddy construction sites, the bolts are easily corroded by mud, which further increases the difficulty of disassembly and assembly. This results in the mud cleaning spoon replacement taking too long and affecting the work efficiency. Therefore, a photovoltaic cast-in-place pile quality inspection and mud cleaning device is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 , Figure 2This utility model provides an embodiment of a photovoltaic cast-in-place pile quality inspection and sludge cleaning device, including a connecting column a1, a support assembly fixedly connected to the outer front side of the connecting column a1, a connecting plate 4 rotatably connected to the outer side of the fixed assembly, a fixing assembly fixedly connected to the outer front side of the connecting column a1, a prismatic plate 7 rotatably connected to the outer side of the fixing assembly, a sludge cleaning spoon 8 fixedly connected to the bottom of the connecting plate 4, the support assembly including a support plate a2, the rear side of the support plate a2 fixedly connected to the front side of the connecting column a1, a screw 3 threadedly connected to the inner thread of the support plate a2, the outer thread of the screw 3 tightly engaging with the inner thread of the support plate a2, axially fixing the connecting plate 4 to the front side of the support plate a2, the connecting plate... The internal rotating connection of 4 is external to screw 3. The fixing component includes a rotating shaft a5. A spring a6 is sleeved on the outside of the rotating shaft a5. When the spring a6 is in its natural state, it is in a slightly compressed state. The rear side of the spring a6 is fixedly connected to the front side of the connecting post a1. The rear side of the connecting plate 4 is in contact with the front side of the connecting post a1. The front side of the connecting plate 4 is in contact with the rear side of the spring a6. The front side of the spring a6 is fixedly connected to the rear side of the prism plate 7. When the prism plate 7 rotates around the rotating shaft a5 under the action of external force, the spring a6 will be further compressed or stretched, storing elastic potential energy. When the external force disappears, the spring a6 releases the elastic potential energy, generating a reverse force, pushing the prism plate 7 to rotate around the rotating shaft a5 back to the initial position.
[0032] Reference Figure 1 , Figure 3 The fixed column 12 is externally fixedly connected to a support plate b13, and a rotating assembly is rotatably connected inside the support plate b13. The fixed column 12 is externally fixedly connected to a spring b15. The telescopic column 10 has multiple holes 11 on its exterior. The telescopic column 10 is a functional component that realizes the length adjustment of the device. In its initial state, it is completely retracted inside the fixed column 12. The rotating assembly includes a rotating shaft b14, which is externally rotatably connected to the interior of the support plate b13. A fixing claw 16 is rotatably connected to the exterior of the rotating shaft b14. One end of the fixing claw 16 is fixedly connected to the right side of the spring b15, and the other end of the fixing claw 16 is slidably connected inside the hole 11. When the telescopic column 10 extends out of or retracts from the fixed column 12, the other end of the fixing claw 16 can slide or engage inside the hole 11.
[0033] Reference Figure 1 , Figure 4A fixing sleeve 9 is fixedly connected to the top of the connecting column a1. The fixing sleeve 9 ensures that the telescopic column 10 will not shake when subjected to reaction force. The telescopic column 10 is fixedly connected inside the fixing sleeve 9. A fixing column 12 is fitted on the outside of the telescopic column 10. The inside of the fixing sleeve 9 is hollow, providing initial storage space for the telescopic column 10. The bottom of the telescopic column 10 is fixedly connected to the top of the connecting column a1. The fixing column 12 has scale lines 17 on its outside, which are evenly distributed along the axial direction of the fixing column 12 and marked with corresponding values to visually display the depth of the fixing column 12 into the ground. A level 18 is fixedly connected inside the fixing column 12. The operator can observe the alignment position of the inner wall of the hole with the scale of the measuring ruler through the level 18. A connecting column b19 is fixedly connected to the top of the fixing column 12. A handle 20 is fixedly connected to the top of the connecting column b19. The surface is covered with a non-slip rubber sleeve to improve grip comfort and friction.
[0034] Working principle: Before operation, the telescopic column 10 is initially stored inside the fixed column 12, and the slag cleaning spoon 8 and other components are in the initial position. The operator holds the handle 20, aligns the device with the drilling point of the photovoltaic grouting pile that needs to be inspected and cleaned, and begins to lower the device.
[0035] When measuring the drilling specifications, since the length of the telescopic column 10 is fixed, as the fixed column 12 gradually goes deeper into the ground, the operator observes the scale line 17 on the outside of the fixed column 12 to read the depth of the fixed column 12 into the ground. The sum of the height of the telescopic column 10, the connecting column a1, and the slag-removing spoon 8 is the depth of the underground drilling. The level 18 fixed inside the fixed column 12 is used for reading. When the fixed column 12 goes deeper into the underground drilling, the inner wall of the drilling will come into contact with the measuring scale of the level 18. The operator observes the alignment position of the inner wall of the drilling with the scale of the measuring scale to determine whether the drilling meets the standard.
[0036] When cleaning the bottom mud, the cleaning spoon 8, which is fixed at the bottom of the connecting plate 4, is lowered to the bottom of the hole along with the device. The prism plate 7 rotates on the rotating shaft a5, and the spring a6 resets the prism plate 7, thereby driving the cleaning spoon 8 to be easily fixed. When the cleaning spoon 8 comes into contact with the mud, the operator applies force through the handle 20, which is transmitted to the cleaning spoon 8 through the connecting column b19, the fixed column 12, the telescopic column 10, the fixed sleeve 9, and the connecting column a1. The cleaning spoon 8 scoops up the mud. Then, the operator pulls the device through the handle 20 to pull the fixed column 12 out from the ground. The telescopic column 10 is retracted into the fixed column 12, and the device returns to its initial state, completing the operation.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
