In recent years, the construction of photovoltaic power plants has shown a trend of expanding into complex terrains. These special geological areas have effectively improved the utilization rate of land resources, but their complex geological conditions pose a severe challenge to the stability of photovoltaic power plant foundations. In mountainous areas with developed rock and coal, the bearing layer of the pile foundation is easily eroded by groundwater, leading to a decrease in bearing capacity. In coal mining backfill areas, due to geological structural damage and the effect of self-weight consolidation, the settlement rate can reach 3-5 times that of conventional sites, and the problem of unstable module arrays caused by uneven settlement of pile foundations is becoming increasingly prominent.

The connection group is used to connect the pile foundation 10 and the sensing component 2. The sensing component 2 can monitor the slight settlement of the pile foundation 10 in real time and has high reliability.

[0032] Specifically, please refer to Figure 1 and Figure 2 The connecting components include a first clamp 11 and a second clamp 12.

Preferably, the first elastic compression member 13 and the second elastic compression member 14 are located on opposite sides of the first clamp 11.

[0033] In this embodiment, a sensing component 2 is installed between each of two adjacent pile foundations 10. Please refer to [link / reference]. Figure 2 and Figure 3 The sensing component 2 includes a housing 21 and two sensing units 22. The two sensing units 22 are arranged crosswise between two adjacent pile foundations 10. The sensing unit 22 includes a meshing rack 221 and a ratchet 222. The rack 221 is installed inside the housing 21, and the ratchet 222 is rotatably installed inside the housing 21. A pointer 223 is installed on the top of the ratchet 222. The surface of the housing 21 is provided with two observation windows 211. The two pointers 223 are respectively facing the two observation windows 211, and the rotation of the pointers 223 can be directly monitored through the observation windows 211.

[0034] Preferably, the tooth pitch of the rack 221 is 2mm, the tooth height is 3mm, and the surface is plated with hard chrome.

[0035] Preferably, the observation window 211 is equipped with a dial, and the rack 221 drives the ratchet 222 to rotate, which in turn causes the head of the pointer 223 on it to rotate along the dial. More preferably, the dial is symmetrically divided into red and green colors, and in the initial state, the head of the pointer 223 points to 0°.

[0036] Optionally, the housing 21 is 4mm thick, made of ASA engineering plastic, with an IP67 protection rating, and the interior of the housing 21 is filled with flame-retardant silicone, and the seams are coated with polysulfide sealant.

[0037] Please see Figure 2 and Figure 3 The rack 221 of one of the sensing units 22 is connected to the first elastic compression member 13 on one of the two adjacent pile foundations 10 and the second clamp 12 on the other pile foundation 10. The rack 221 of the other sensing unit 22 is connected to the second clamp 12 on one of the two adjacent pile foundations 10 and the second elastic compression member 14 on the other pile foundation 10.

[0038] Optionally, please refer to Figure 2 and Figure 3 The first elastic compression member 13 includes a first compression spring 131 and a first tension rod 132, wherein one end of the first tension rod 132 is connected to one side of the first clamp 11, one end of the first compression spring 131 is connected to the other end of the first tension rod 132, and the other end of the first compression spring 131 is connected to one end of the corresponding rack 221. The second elastic compression member 14 includes a second compression spring 141 and a second tension rod 142, one end of the second tension rod 142 is connected to the opposite side of the first clamp 11, one end of the second compression spring 141 is connected to the other end of the second tension rod 142, and the other end of the second compression spring 141 is connected to one end of the corresponding rack 221.

[0039] Preferably, please continue reading. Figure 2 and Figure 3 A third tie rod 15 and a fourth tie rod 16 are connected to the opposite sides of the second clamp 12 to realize the connection between the second clamp 12 and the rack 221.

[0040] That is, one of the racks 221 in the housing 21 is connected to the first compression spring 131 on one of the two adjacent pile foundations 10 and the third tie rod 15 on the other pile foundation 10, and the other rack 221 in the housing 21 is connected to the fourth tie rod 16 on one of the two adjacent pile foundations 10 and the second compression spring 141 on the other pile foundation 10.

[0041] With the above settings, the first compression spring 131 and the second compression spring 141 are always in a compressed state. When a certain pile foundation 10 settles, the second clamp 12 connected to the pile foundation 10 drives the first compression spring 131 and the second compression spring 141 connected to it to release elastic potential energy, thereby driving the two racks 221 connected to the second clamp 12 on the pile foundation 10 to drive the corresponding ratchet 222 to rotate, thereby driving the pointer 223 to rotate, so that the slight settlement of the pile foundation 10 can be directly monitored through the observation window 211.

[0042] For example, the first tie rod 132 and the second tie rod 142 are both made of stainless steel with a diameter of 20mm and a tensile strength of ≥600MPa. The first clamp 11 and the second clamp 12 are also made of stainless steel and have excellent corrosion resistance.

[0043] In this embodiment, the first tie rod 132 and the third tie rod 15 connected to the same rack 221 are arranged in a straight line, and the second tie rod 142 and the fourth tie rod 16 connected to the same rack 221 are arranged in a straight line. A laser rangefinder is used to adjust the included angle of the first tie rod 132 and the fourth tie rod 16 connected to the same pile foundation 10 to 90°±0.5, and the included angle of the second tie rod 142 and the third tie rod 15 connected to the same pile foundation 10 to 90°±0.5, to ensure that the first tie rod 132, the second tie rod 142, the third tie rod 15 and the fourth tie rod 16 are subjected to uniform force.

[0044] Furthermore, in this embodiment, the motion trajectory of the rack 221 is calibrated by a dial indicator to be parallel to the axis of the first tie rod 132 and the third tie rod 15 connected thereto, or parallel to the axis of the second tie rod 142 and the fourth tie rod 16 connected thereto.

[0045] It should be noted that one end of the first compression spring 131 is pinned to the first tie rod 132, and the other end of the first compression spring 131 is connected to the corresponding rack 221 through an adjusting nut. One end of the second compression spring 141 is pinned to the second tie rod 142, and the other end of the second compression spring 141 is connected to the corresponding rack 221 through an adjusting nut.

[0046] Preferably, the initial pre-compression of the first compression spring 131 and the second compression spring 141 is 20% of the total stroke, and their preload is controlled to be 160-200N.

[0047] More preferably, in this embodiment, a first compression spring 131 and a second compression spring 141 with a strength of 0.8 kN / m are configured in the soft soil area, and a first compression spring 131 and a second compression spring 141 with a strength of 1.2 kN / m are configured in the backfill area, in order to adapt to different geological conditions.

[0048] In some feasible embodiments, displacement sensors are used to calibrate the linear relationship between the tension of the first compression spring 131 and the second compression spring 141 and the settlement of the pile foundation 10, ensuring that for every 1 mm settlement of the pile foundation 10, the tension of the first compression spring 131 and the second compression spring 141 connected to the second clamp 12 is 0.4 mm.

[0049] In some feasible embodiments, it is further calibrated that for every 2 mm that the rack 221 moves, it drives the ratchet 222 and the pointer 223 engaged therewith to rotate 10°.

[0050] The pile foundation settlement monitoring device provided in this embodiment also includes an alarm component, which is used to issue an alarm to remind the staff after the ratchet 222 rotates to a preset angle.

[0051] For example, please refer to Figure 3 and Figure 4 The alarm assembly includes two alarm units 31, each corresponding to one of the two sensing units 22. Each alarm unit 31 includes an infrared sensor 311 and an alarm 312 installed inside the housing 21. The infrared sensor 311 is configured to monitor the position of the corresponding pointer 223, and is connected to the corresponding alarm 312. With this configuration, when the ratchet 222 rotates the pointer 223 to a preset angle, the head of the pointer 223 triggers the sensing end of the infrared sensor 311, which in turn triggers the corresponding alarm 312, issuing an alarm to alert personnel.

[0052] Specifically, please refer to Figure 3 and Figure 4 The infrared sensor 311 is installed on the side away from the head of the pointer 223 along the axis of the pointer 223. After the pile foundation 10 settles by 50mm, the rack 221 moves by 36mm. The ratchet 222 drives the pointer 223 to rotate 180°. The head of the pointer 223 is located directly above the sensing end of the infrared sensor 311 and rotates to the preset angle.

[0053] Preferably, after the ratchet 222 rotates 180°, the distance between the head of the pointer 223 and the sensing end of the infrared sensor 311 is 15mm, ensuring the sensing accuracy of the infrared sensor.

[0054] In some feasible embodiments, the length of the rack 221 is set to 36mm. After the rack 221 moves 36mm, the ratchet 222 engaged with the rack 221 disengages from it.

[0055] To ensure that the alarm 312 continues to sound after the pile foundation 10 settles by 50mm, this embodiment also provides a permanent magnet 313 on one side of the infrared sensor 311. The rack 221 moves 36mm, and the ratchet 222 drives the pointer 223 to rotate 180°. After the ratchet 222 disengages, the head of the pointer 223 is located directly above the sensing end of the infrared sensor 311 and is attracted and locked by the permanent magnet 313, ensuring that the infrared sensor 311 continuously triggers the corresponding alarm 312. External force must be applied by the staff to reset it.

[0056] Optionally, the alarm 312 includes a buzzer and a strobe light, both of which are connected to a corresponding infrared sensor 311. The infrared sensor 311 can simultaneously trigger the strobe light and the buzzer.

[0057] It should be noted that the infrared sensor 311, buzzer, and strobe light are powered by the photovoltaic panel, which is installed inside the housing 21 and electrically connected to the infrared sensor 311, buzzer, and strobe light. Correspondingly, an ultraviolet-proof cover is added to the outside of the housing 21 to ensure the output power of the photovoltaic panel.

[0058] Furthermore, the infrared sensor 311 integrates a communication interface, which is electrically connected to the central control platform to transmit information simultaneously when the alarm 312 is triggered.

[0059] The pile foundation settlement monitoring device provided in this embodiment, when a certain pile foundation 10 settles, the second clamp 12 connected to the pile foundation 10 drives the first compression spring 131 and the second compression spring 141 connected to it to release elastic potential energy, thereby driving the two racks 221 connected to the second clamp 12 on the pile foundation 10 to drive the corresponding ratchet 222 to rotate, thereby driving the pointer 223 to rotate. Thus, the minute settlement of the pile foundation 10 can be directly monitored by the rotation angle of the pointer 223. Furthermore, after the ratchet 222 drives the pointer 223 to rotate 180°, the ratchet 222 disengages from the rack 221 it is engaged with. At this time, the head of the pointer 223 is directly above the sensing end of the infrared sensor 311, triggering the corresponding alarm 312 to issue an alarm to remind the staff. Before the staff handles the situation, the permanent magnet 313 attracts and locks the pointer 223, continuously triggering the corresponding alarm 312.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
