[0003] The mountain photovoltaic pile foundation borehole diameter measuring device is a tool specifically designed for measuring the borehole diameter of mountain photovoltaic pile foundations. It can obtain borehole diameter data efficiently, accurately, and safely, greatly improving the efficiency and accuracy of measurement work.

[0004] Patent CN217716247U discloses a pile hole diameter measuring device. The pile hole diameter can be obtained by adding the maximum value exposed on the first scale line and the maximum value on the second scale line. The operation is convenient and simple. Although the measuring device can measure the pile hole diameter, the size of the pile hole diameter that can be measured is determined by the length of the box. Therefore, in actual measurement, the range of pile hole diameter measurement is small and the adaptability is low.

[0005] Patent CN222414827U discloses a hole diameter measuring device for mountain photovoltaic pile foundations, providing a solution for drilling engineering that is operable by a single person, portable, capable of measuring different heights, and efficient, accurate, and safe. Although the device can measure the hole diameter of the pile foundation, the size of the pile foundation hole diameter that can be measured is determined by the size of the first gear. Therefore, in actual measurement, the range of pile foundation hole diameter that can be measured is small and the adaptability is low. Utility Model Content

[0030] Please see Figure 1 - Figure 4 As shown, a mountain photovoltaic pile foundation borehole measuring device includes a sleeve 1, which is used to house various components.

[0031] The sleeve 1 is cylindrical, which makes it easy to insert the sleeve 1 into the pile foundation hole.

[0032] The upper end of the sleeve 1 is connected to a top cover 11, which is used to block soil and prevent soil from entering the sleeve 1 from the top.

[0033] With an opening at the bottom of the sleeve 1, the soil enters the sleeve 1 through the movable groove 2 and falls down from the opening at the bottom of the sleeve 1 under its own weight.

[0034] The sleeve 1 has symmetrically arranged movable grooves 2 in the middle, which are used to provide movement space.

[0035] The sleeve 1 is rotatably connected to the position of the movable groove 2 with the first swing arm 21 arranged symmetrically. The first swing arm 21 is located in the movable groove 2. By rotating the first swing arm 21 to the outside of the sleeve 1, the transmitter 23 and the receiver 24 can be moved away from each other, thereby adjusting the diameter of the pile foundation hole.

[0036] The upper end of the first swing arm 21 is rotatably connected to the sleeve 1, and the lower ends of adjacent first swing arms 21 are respectively rotatably connected to support seats 22, which are used to support and fix the transmitter 23 or the receiver 24.

[0037] A transmitter 23 is installed on the upper surface of one of the support bases 22, and a receiver 24 is installed on the upper surface of the other support base 22. Through the cooperation of the transmitter 23 and the receiver 24, the diameter of the pile foundation hole can be measured.

[0038] A drive rod 3 is connected between the upper ends of adjacent first swing arms 21. The drive rod 3 is used to assist in driving the first swing arm 21 to rotate.

[0039] Inside the sleeve 1, a drive shaft 31 is provided at the position between the two drive rods 3. The drive shaft 31 is used to synchronously drive the first chain 34 and the second chain 37 to rotate.

[0040] One end of the drive shaft 31 is connected to a motor 38, which is used to drive the drive shaft 31 to rotate.

[0041] Inside the sleeve 1, a mounting base 39 is connected to the position corresponding to the motor 38. The motor 38 is mounted on the mounting base 39, which is used to fix the position of the motor 38.

[0042] One of the drive rods 3 has a first sprocket 32 ​​connected to one side of its outer end. A second sprocket 33 is connected to the drive shaft 31 at the position corresponding to the first sprocket 32. A first chain 34 meshes with the outer sides of the first sprocket 32 ​​and the second sprocket 33. Through the cooperation of the first sprocket 32, the second sprocket 33 and the first chain 34, one of the first swing arms 21 can rotate.

[0043] Another drive rod 3 is connected to a fourth sprocket 36 on the outer side of the end away from the first sprocket 32. The drive shaft 31 is connected to a third sprocket 35 at the position corresponding to the fourth sprocket 36. The third sprocket 35 and the fourth sprocket 36 are meshed with a second chain 37 on the outer side. Through the cooperation of the third sprocket 35, the fourth sprocket 36 and the second chain 37, the other first swing arm 21 can be rotated.

[0044] The end of the drive shaft 31 away from the motor 38 is connected to a worm 4. The worm 4 is rotatably connected inside the sleeve 1. A worm wheel 41 meshes with the outside of the worm 4. Through the cooperation between the worm wheel 41 and the worm 4, after the drive shaft 31 has rotated, the worm wheel 41 and the worm 4 will self-lock, thereby fixing the position of the first swing arm 21 and the second swing arm 25, preventing the first swing arm 21 and the second swing arm 25 from deflecting, and enabling accurate measurement of the diameter of the pile foundation hole.

[0045] Inside the sleeve 1, a fixed seat 42 is connected to the position corresponding to the worm gear 41. The worm gear 41 is rotatably connected to the fixed seat 42, and the fixed seat 42 is used to fix the position of the worm gear 41.

[0046] Inside the sleeve 1, corresponding to the position of the first swing arm 21, there are symmetrically arranged second swing arms 25, which are used to limit the state of the support base 22.

[0047] The inner side of the sleeve 1 is connected to the overlapping plate 26 corresponding to the position of the second swing arm 25. The overlapping plate 26 is used to fix the position of the second swing arm 25.

[0048] The upper end of the second swing arm 25 is rotatably connected to the overlapping plate 26, and the lower end of the second swing arm 25 is rotatably connected to the support base 22. The position of the second swing arm 25 can be limited by the cooperation between the overlapping plate 26 and the support base 22.

[0049] The second swing arm 25 is the same length as the first swing arm 21, and the second swing arm 25 is arranged parallel to the first swing arm 21. With this arrangement, when the first swing arm 21 and the second swing arm 25 rotate, it can be ensured that the support seat 22 is always in a horizontal state, preventing the support seat 22 from deflecting.

[0050] The second swing arm 25 is set at a lower height than the first swing arm 21. This setting ensures that the first swing arm 21 and the second swing arm 25 can rotate synchronously to the outside of the sleeve 1.

[0051] Inside the sleeve 1, corresponding to the positions between the two sets of second swing arms 25, limit plates 5 are connected respectively. The limit plates 5 are used to block the second swing arms 25 and prevent the first swing arm 21 from entering the sleeve 1.

[0052] In practical use, a traction rope is connected to the upper end of the sleeve 1. The sleeve 1 is then inserted into the pile foundation hole using the traction rope. Once it reaches the designated position, the motor 38 is started, causing the drive shaft 31 to rotate. During the rotation of the drive shaft 31, the first sprocket 32 ​​and the third sprocket 35 are simultaneously rotated. The first sprocket 32, in conjunction with the second sprocket 33 and the first chain 34, drives one set of first swing arms 21 and second swing arms 25 to rotate outwards from the sleeve 1. The third sprocket 35, in conjunction with the fourth sprocket 36 and the second chain 37, drives another set of first swing arms 21 and second swing arms 25 to rotate outwards from the sleeve 1. The first swing arm 21 and the second swing arm 25 of the outer set rotate synchronously to the outside of the sleeve 1. During the rotation of the first swing arm 21 and the second swing arm 25, the support base 22 will always be in a horizontal state. After both support bases 22 are in contact with the inner wall of the pile hole, the diameter of the pile hole can be measured with the cooperation of the transmitter 23 and the receiver 24. The operation is simple and convenient, and the size of the hole that can be measured is determined by the length of the first swing arm 21 and the second swing arm 25. It can measure the diameter of more specifications of pile holes, thus improving adaptability.
