Description

Technical Field

[0001] This invention relates to the field of angle measurement technology, and more specifically, to a device and method for measuring the tilt angle of pile foundations used in photovoltaic projects. Background Technology

[0002] To ensure the stability of photovoltaic base piles during installation, after the base piles are pre-inserted into the installation position, an inclination angle measuring device is used to measure the inclination angle of the pre-installed position. Once the inclination angle reaches the preset value, the base piles are then fixed.

[0003] In the prior art, such as CN116697932A, a device for measuring the tilt angle of a building is disclosed. This device includes a support plate, a reflector fixed to the lower surface of the support plate with an origin point on the reflector, and a measuring ruler comprising a support base, a telescopic rod, and an arc-shaped ruler plate fixed to the top of the telescopic rod with graduations. A laser emitter is fixed to the support base of the measuring ruler. While this device achieves the measurement of the tilt angle, the contact mechanism between the support plate, reflector, and support base and the object to be measured is used separately from the arc-shaped ruler plate. During measurement, the contact mechanism must first be aligned with the object, and then the position of the arc-shaped ruler plate must be adjusted accordingly to match the contact mechanism. The entire measurement process is cumbersome, and the repeated adjustments can easily affect the measurement accuracy. Therefore, there is a need for a tilt angle measuring device that is convenient to use, simple to operate, and has high measurement accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for measuring the tilt angle of pile foundations for photovoltaic engineering, so as to solve the above-mentioned technical problems.

[0005] The present invention solves the above-mentioned technical problems through the following technical solutions: In a first aspect, the present invention provides a pile foundation tilt angle measuring device for photovoltaic engineering, comprising: a support mechanism and an angle measuring mechanism, wherein the support mechanism is connected to the angle measuring mechanism, and the support mechanism has the function of calibrating the setting posture of the angle measuring mechanism so that the overall horizontal setting posture of the angle measuring mechanism is flush with the horizontal ground. The angle measuring mechanism includes a measuring contact head, an alignment drive assembly, and a measuring angle reading assembly. The measuring contact head is used to contact the outer side of the pile foundation to be measured. The angle measurement and reading component includes a laser emitting part, an angle reading part, and a limiting part. The laser emitting part includes a rotating end, a sliding end, and a connecting end. The rotating end of the laser emitting part is rotatably connected to the top of the alignment drive component. The sliding end of the laser emitting part is slidably connected to the limiting part. The connecting end of the laser emitting part is detachably connected to the measuring contact head. The angle reading part is fixedly connected to the sliding end of the laser emitting part, and the limiting part is fixedly connected to the alignment drive component. When measuring the tilt angle of the pile foundation, the alignment drive assembly drives the laser emitting part and the measuring contact head to swing upward together and approach the outside of the pile foundation. Meanwhile, the sliding end of the laser emitting part slides synchronously along the preset route of the limiting part, so that the laser emitted by the laser emitting part is always aligned with the preset angle value on the angle reading part and can be directly read. When the measuring contact head contacts the outside of the pile foundation and remains parallel, the angle value of the laser emitted by the laser emitting part illuminating the angle reading part is recorded as the current tilt angle value of the pile foundation.

[0006] As a further optimization of the present invention, the laser emitting part includes a swing rod, a laser emitter, and a synchronization rod; the angle reading part includes an angle value scale; the limiting part includes an arc guide rail; one end of the swing rod is rotatably connected to the top of the alignment drive assembly, and the other end is connected to the measuring contact head; the top end of the synchronization rod is fixedly connected to the outside of the swing rod, and its bottom end is slidably connected to the arc guide rail; the arc guide rail is fixedly installed on one side of the alignment drive assembly; the angle value scale is fixedly installed at the bottom end of the synchronization rod; the center of the arc guide rail coincides with the rotation center of the swing rod; and the laser emitted by the laser emitter points to the center of the angle value scale.

[0007] As a further optimization of the present invention, the alignment drive assembly includes a support base, a drive screw, a sliding frame, and a slider. The bottom of the support base is connected to a support mechanism. The drive screw is rotatably mounted on the bottom of the support base.

[0008] As a further optimization of the present invention, the measuring contact head is an automatic distance measuring device, which includes a mounting plate, a control board, a buzzer, and two distance measuring sensors. The two distance measuring sensors are symmetrically installed on the side of the mounting plate away from the swing arm. The control board is installed inside the mounting plate. The buzzer and the distance measuring sensors are both signal-connected to the control board. The two distance measuring sensors are used to measure the straight-line distance between the mounting plate and the outer side of the pile foundation, and send the measurement results to the control board in real time. When the control board receives the same measurement results from the two distance measuring sensors, it controls the buzzer to sound, confirming that the measuring contact head has moved to a position parallel to the pile foundation.

[0009] As a further optimization of the present invention, the measuring contact head is a contact compression device, which includes a mounting plate, a control plate, two contact rods, two return springs, two indicator lights, and two contact switches. The control plate is installed inside the mounting plate. The two contact rods are symmetrically slidably installed at the upper and lower ends of the mounting plate on the side away from the swing rod. The maximum displacement of the upper contact rod is twice that of the lower contact rod. When the upper contact rod reaches half of its maximum displacement, it contacts the corresponding contact switch, and when the lower contact rod reaches its maximum displacement, it contacts the corresponding contact switch. The two return springs are respectively fitted on the outside of the two contact rods. The two contact switches are electrically connected to the two indicator lights one-to-one. The two contact switches and the two indicator lights are all installed on the control plate, and the two contact switches are distributed one-to-one with the ends of the two contact rods. After the ends of the two contact rods contact the contact switches at the corresponding positions, the indicator lights connected to the corresponding contact switches are lit. When one of the indicator lights lights up first and then goes out, and the other indicator light continues to light up, it is determined that the measuring contact head has moved to a position parallel to the pile foundation.

[0010] As a further optimization of the present invention, a shrinkage groove is provided on one side of the support base, and the height of the shrinkage groove is greater than the swing radius of the angle measuring component.

[0011] As a further optimization of the present invention, the support mechanism includes a base, a horizontal attitude indicator component, and an attitude adjustment component. The horizontal attitude indicator component is connected to one side of the alignment drive component. After the bottom of the base contacts the ground, the horizontal attitude indicator component is used to reflect the current horizontal attitude of the angle measuring mechanism. The attitude adjustment component is installed on the base, and one end of it is connected to the bottom of the alignment drive component. The attitude adjustment component is used to adjust the angle measuring mechanism to a preset horizontal measurement attitude.

[0013] As a further optimization of the present invention, the horizontal attitude indicator component is an integrated mini level, which is mounted on one side of the alignment drive component.

[0014] Secondly, the present invention also provides a method for measuring the tilt angle of pile foundations for photovoltaic projects. Using the aforementioned device for measuring the tilt angle of pile foundations for photovoltaic projects includes the following operating steps: S1. Place the angle measuring device between the pile foundation and the ground, so that the bottom of the support mechanism is in contact with the ground; S2. Based on the horizontal attitude displayed by the support mechanism, adjust the horizontal attitude of the angle measuring mechanism to be flush with the horizontal ground; S3. The alignment drive component drives the angle measurement reading component and the measurement contact head to move closer to the pile foundation. The sliding end of the laser emitting part slides synchronously along the preset route of the limiting part, so that the laser emitted by the laser emitting part is always aligned with the preset angle value on the angle reading part and can be directly read. S4. When the measuring contact head contacts the pile foundation and remains parallel to the pile foundation, stop driving the measuring contact head. The angle value of the laser emitted by the laser emitting unit illuminating the angle reading unit is recorded as the current tilt angle value of the pile foundation.

[0015] The beneficial effects of this invention are as follows: The tilt angle measuring device of this invention integrates the measuring contact head, the alignment drive component, and the angle reading component into a single unit, with all components working in tandem. In use, simply operate the alignment drive component to move the measuring contact head to a position parallel to the pile foundation, and then directly read the angle value displayed on the angle reading component. During the measurement process, there is no need for cumbersome adaptation and adjustment operations, which not only ensures the accuracy of the measurement but also enables rapid measurement of the tilt angle, making it very convenient to use. In addition, when not in use, the device can be retracted for easy transfer and storage. Attached Figure Description

Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0019] Please refer to the following: Figures 1 to 2A device for measuring the tilt angle of a photovoltaic (PV) foundation includes: a support mechanism 2 and an angle measuring mechanism 3. The support mechanism 2 is connected to the angle measuring mechanism 3. The support mechanism 2 has the function of calibrating the setting posture of the angle measuring mechanism 3 so that the overall horizontal setting posture of the angle measuring mechanism 3 is flush with the horizontal ground. The angle measuring mechanism 3 includes a measuring contact head 31, an alignment drive component 32, and a measuring angle reading component 33. The measuring contact head 31 is used to contact the outside of the PV foundation 1 to be measured. The measuring angle reading component 33 includes a laser emitting part, an angle reading part, and a limiting part. The laser emitting part includes a rotating end, a sliding end, and a connecting end. The rotating end of the laser emitting part is rotatably connected to the top of the alignment drive component 32. The sliding end of the laser emitting part is slidably connected to the limiting part. The connecting end of the laser emitting part is detachably connected to the measuring contact head 31. The angle reading part is fixedly connected to the sliding end of the laser emitting part, and the limiting part is fixedly connected to the alignment drive component 32. When measuring the tilt angle of the photovoltaic pile foundation 1, the laser emitting part and the measuring contact head 31 are driven to swing upward together and approach the outside of the photovoltaic pile foundation 1 by the alignment drive component 32. The sliding end of the laser emitting part slides synchronously along the preset route of the limiting part, so that the laser emitted by the laser emitting part is always aligned with the preset angle value on the angle reading part and can be directly read. When the measuring contact head 31 contacts the outside of the photovoltaic pile foundation 1 and remains parallel, the angle value of the laser emitted by the laser emitting part illuminating the angle reading part is recorded as the current tilt angle value of the photovoltaic pile foundation 1.

[0020] For details, please refer to the following: Figure 2 , Figure 6 and Figure 7 The support mechanism 2 includes a base 21, a horizontal attitude indicator 22, and an attitude adjustment component 23. The horizontal attitude indicator 22 is connected to one side of the alignment drive component 32. After the bottom of the base 21 contacts the ground, the horizontal attitude indicator 22 reflects the current horizontal attitude of the angle measuring mechanism 3. The attitude adjustment component 23 is mounted on the base 21, with one end connected to the bottom of the alignment drive component 32. The attitude adjustment component 23 is used to adjust the angle measuring mechanism 3 to a preset horizontal attitude. The horizontal attitude indicator 22 is an integrated mini level, which is mounted on one side of the alignment drive component. The attitude adjustment assembly 23 includes an adjustment screw 231, a rotating rod 232, a connecting rotating seat 233, and a driving block 234. The top of the base 21 has a movable groove 235. The adjustment screw 231 is rotatably installed inside the base 21, and one end of it is rotatably connected to the inner side wall of the movable groove 235. The connecting rotating seat 233 is connected to the bottom of the alignment drive assembly 32, and its two sides are rotatably connected to the two sides of the inner side wall of the movable groove 235 respectively. The bottom of the driving block 234 is slidably connected to the inner bottom wall of the movable groove 235, and the driving block 234 is threadedly fitted on the outside of the adjustment screw 231.

[0021] It should be noted that the usage process of the aforementioned support mechanism 2 is as follows: Since the angle measuring device of the present invention is in a retracted state when not in use, first place the angle measuring device of the present invention on the ground layer close to the photovoltaic pile foundation 1, and then start adjusting the horizontal angle of the support mechanism 2. By observing the current horizontal state displayed by the level, start rotating the adjusting screw 231 accordingly, so that the driving block 234 slides linearly along the bottom wall of the movable groove 235. The rotating rod 232 starts to rotate under the driving action of the driving block 234. Under the rotation action of the rotating rod 232, the connecting rotating seat 233 and the entire angle measuring mechanism 3 rotate together, and the level also rotates together with the alignment driving component 32. When observing... Once the level indicator displays a standard horizontal state, the adjusting screw 231 stops rotating, the drive block 234 stops moving, and the rotating rod 232, connecting pivot 233, and support base 321 also stop moving, thus completing the horizontal attitude adjustment of the angle measuring mechanism 3. Therefore, the support mechanism 2 provided in this invention, in addition to providing stable support for the angle measuring mechanism 3, also has the function of adjusting the horizontal attitude of the angle measuring mechanism 3. During the adjustment process, it is only necessary to rotate the adjusting screw 231 according to the current state displayed by the level indicator. The adjustment operation is simple and convenient, ensuring that the angle measuring mechanism 3 is in a standard horizontal position, thereby ensuring the accuracy of its measurement.

[0022] For details, please refer to the following: Figures 2 to 4The laser emitting part includes a swing rod 331, a laser emitter 332, and a synchronization rod 333. The angle reading part includes an angle value scale 334. The limiting part includes an arc guide rail 335. One end of the swing rod 331 is rotatably connected to the top of the alignment drive assembly 32, and the other end is connected to the measuring contact head 31. The top end of the synchronization rod 333 is fixedly connected to the outside of the swing rod 331, and its bottom end is slidably connected to the arc guide rail 335. The arc guide rail 335 is fixedly installed on one side of the alignment drive assembly 32. The angle value scale 334 is fixedly installed at the bottom end of the synchronization rod 333. The center of the arc guide rail 335 coincides with the rotation center of the swing rod 331. The laser emitted by the laser emitter 332 points to the center of the angle value scale 334. The alignment drive assembly 32 includes a support base 321, a drive screw 322, a sliding frame 323, and a slider 324. A level is fixedly mounted on the lower end of one side of the support base 321. The bottom of the support base 321 is connected to the support mechanism 2. A contraction groove 325 is provided on one side of the support base 321, and the height of the contraction groove 325 is greater than the swing radius of the angle measuring assembly. The drive screw 322 is rotatably mounted on the bottom of the support base 321. The bottom of the sliding frame 323 is slidably connected to the bottom of the support base 321. The outer side of the drive screw 322 is threadedly connected to the bottom of the sliding frame 323. The slider 324 is slidably connected to the inner side of the sliding frame 323. One side of the slider 324 is fixedly connected to the bottom of the angle value scale 334. The measuring contact head 31 is an automatic distance measuring device, which includes a mounting plate 311, a control board 312, a buzzer 313, and two distance sensors 314. The two distance sensors 314 are symmetrically installed on the side of the mounting plate 311 away from the swing rod 331. The control board 312 is installed inside the mounting plate 311. Both the buzzer 313 and the distance sensors 314 are connected to the control board 312 for signaling. Both distance sensors 314 are used to measure the straight-line distance between the mounting plate 311 and the outer side of the photovoltaic pile base 1, and send the measurement results to the control board 312 in real time. When the control board 312 receives the same measurement results from the two distance sensors 314, it controls the buzzer 313 to sound, confirming that the measuring contact head 31 has moved to a position parallel to the photovoltaic pile base 1.

[0023] Please refer to the following: Figure 8It should be noted that the above-mentioned angle measuring mechanism 3 is used as follows: After the horizontal attitude of the angle measuring mechanism 3 is adjusted by the support mechanism 2, the forward rotation of the drive screw 322 can drive the sliding frame 323 to slide linearly on the bottom wall of the support base 321. The angle value scale 334 moves synchronously with the sliding frame 323. Under the action of the angle value scale 334, the bottom end of the synchronous rod 333 begins to slide along the arc guide rail 335. Under the action of the synchronous rod 333, the swing rod 331 begins to swing upward. When the synchronous rod 333 slides along the arc guide rail 335, the angle value scale 334 slides vertically on the sliding frame 323. The measuring contact head 31 swings along with the swing rod 331, gradually moving closer to the outside of the photovoltaic pile base 1. During the swinging process of the measuring contact head 31, the distance between it and the photovoltaic pile base is measured in real time by two distance sensors 314. The distance between 1 and 2 is measured, and the measured data is sent to the controller in real time. When the controller receives two measurement values ​​that are the same, it starts the buzzer 313 to make a sound. After hearing the buzzer, the staff determines that the measuring contact head 31 is parallel to the photovoltaic pile 1, and stops rotating the drive screw 322. The sliding frame 323, the angle value scale 334, the synchronization rod 333, and the swing rod 331 stop moving. At this time, the tilt angle of the photovoltaic pile 1 is obtained by reading the scale on the angle value scale 334 where the laser emitted by the laser emitter 332 falls. To ensure the accuracy of the measurement, the above measurement operation can be repeated. After the measurement is completed, the drive screw 322 is rotated in the opposite direction, which makes the swing rod 331 swing the measuring contact head 31 downward together. When the swing rod 331 and the measuring contact head 31 move into the shrinkage groove 325, the drive screw 322 stops rotating. Thus, the tilt angle measuring device of the present invention integrates the measuring contact head 31, the alignment drive component 32, and the angle reading component into a single unit, with all components moving in conjunction with each other. In use, simply operate the alignment drive component 32 to drive the measuring contact head 31 to a position parallel to the photovoltaic pile foundation 1, and the angle value displayed on the angle reading component can be directly read. During the measurement process, there is no need for cumbersome adaptation and adjustment operations, which not only ensures the accuracy of the measurement but also enables the rapid measurement of the tilt angle. It is very convenient to use. In addition, when not in use, the device can be adjusted to a retracted state for easy transfer and storage.

[0024] Example 2 Please refer to the following: Figure 5The present invention also provides another embodiment of the measuring contact head 31, which differs from the first embodiment in that: the measuring contact head 31 is a contact compression device, which includes a mounting plate 311, a control plate 312, two contact rods 315, two return springs 316, two indicator lights 317, and two contact switches 318. The control plate 312 is installed inside the mounting plate 311. The two contact rods 315 are symmetrically slidably installed at the upper and lower ends of the side of the mounting plate 311 away from the swing rod 331, and the maximum displacement of the upper contact rod 315 is twice that of the lower contact rod 315. The two return springs 316 are respectively fitted onto two... On the outside of the contact rod 315, two contact switches 318 and two indicator lights 317 are electrically connected in a one-to-one correspondence. The two contact switches 318 and the two indicator lights 317 are both mounted on the control board 312, and the two contact switches 318 and the ends of the two contact rods 315 are distributed in a one-to-one correspondence. After the ends of the two contact rods 315 contact the corresponding contact switches 318, the indicator lights 317 connected to the corresponding contact switches 318 will be lit. When one indicator light 317 lights up and then goes out, and the other indicator light 317 continues to light up, it is determined that the measuring contact head 31 has moved to a position parallel to the photovoltaic pile base 1.

[0025] It should be noted that the above-mentioned contact compression device operates as follows: When the swing rod 331 swings upwards and approaches the photovoltaic pile base 1, the measuring contact head 31 moves along with the swing rod 331. The upper contact rod 315, located on the outside of the mounting plate 311, first contacts the outside of the photovoltaic pile base 1. As the swing rod 331 continues to swing upwards, the upper contact rod 315 is compressed and retracts into the mounting plate 311. The return spring 316 then contracts the compression of the contact rod 315. When the upper contact rod 315 moves to half of its maximum displacement, its inner end on the mounting plate 311 contacts the corresponding contact switch 318, turning on the indicator light 317 connected to the contact switch 318. Since the contact switch 318 itself has a certain amount of compression, it will not temporarily hinder the swing rod 331 from continuing to swing upwards. When the outer end of the lower contact rod 315 contacts the outside of the photovoltaic pile base 1, it begins to retract into the mounting plate 311. At this time, the upper contact rod 315 is... When the upper part of the mounting plate 311 gradually moves away from the photovoltaic pile base 1, the upper contact rod 315 gradually extends outward under the elastic force of the reset spring 316 connected to it. When the lower contact rod 315 is compressed to the maximum displacement, one end of its inner side contacts the corresponding contact switch 318, causing the indicator light 317 connected to the contact switch 318 to light up. The upper contact rod 315 reaches half of its displacement. Since one end of its inner side is still in contact with the corresponding contact switch 318, the corresponding indicator light 317 remains lit. At this time, the two contact rods 315 are compressed to the same displacement. Therefore, when the staff observes that both indicator lights 317 are lit, they can determine that the measuring contact head 31 has moved to a position parallel to the photovoltaic pile base 1. Then, the rotation of the drive screw 322 can be stopped, and the position value of the laser emitter 332 irradiated on the angle value scale 334 can be read.

[0026] Example 3 A method for measuring the inclination angle of pile foundations used in photovoltaic projects, applicable to the aforementioned inclination angle measuring device for pile foundations used in photovoltaic projects, includes the following operating steps: S1. Place the angle measuring device between the photovoltaic pile base 1 and the ground, so that the bottom of the support mechanism 2 is in contact with the ground; S2. Based on the horizontal posture displayed by the support mechanism 2, adjust the horizontal posture of the angle measuring mechanism 3 to be flush with the horizontal ground; S3. The alignment drive component 32 drives the angle measurement reading component 33 and the measurement contact head 31 to move closer to one side of the photovoltaic pile foundation 1. The sliding end of the laser emitting part slides synchronously along the preset route of the limiting part, so that the laser emitted by the laser emitting part is always aligned with the preset angle value on the angle reading part that can be directly read. S4. When the measuring contact head 31 contacts the photovoltaic pile base 1 and remains parallel to the photovoltaic pile base 1, stop driving the measuring contact head 31 to move. The angle value of the laser emitted by the laser emitting unit illuminating the angle reading unit is recorded as the current tilt angle value of the photovoltaic pile base 1.

The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
