Description

Technical Field

[0001] The present invention relates to the field of structural safety, and in particular to a prestressed intelligent control device for a flexible photovoltaic support. Background Art

[0002] With the gradual implementation of new energy development strategies, photovoltaic power generation has become a key component of my country's energy development strategy and the adjustment of its power structure. However, due to the gradual reduction of traditional photovoltaic land and the numerous constraints of traditional rigid photovoltaic mounting systems, flexible photovoltaic mounting systems have emerged. Flexible photovoltaic mounting systems have low site requirements, wide applicability, and flexibility, effectively shortening construction periods and reducing photovoltaic power generation costs. These advantages have led to widespread adoption and industry recognition.

[0003] Flexible photovoltaic supports generally use a cable structure. In order to ensure the stability of the photovoltaic structure, prestress is applied to the cables. Once the prestress loss of the flexible support reaches a relatively serious level, the structure will be at risk of instability, often causing hidden cracks in the photovoltaic panels, affecting the efficiency of photovoltaic power generation and many other problems. The reasons for the loss of prestress in the cables of flexible supports are complex and diverse, generally including friction loss, anchor loss, temperature difference loss, relaxation and creep of the cables, and prestress loss caused by batch tensioning. At present, there is no good way to solve the problem of prestress loss in cables. It can only be done to avoid delaying the loss of prestress as much as possible, and the cable tension cannot be adjusted subsequently according to the photovoltaic working conditions.

[0004] To address this issue, the present invention adopts a different approach to solve the problem of prestress loss in photovoltaic support cables. By installing an intelligent prestress control device for flexible photovoltaic support cables, the cable tension in the photovoltaic support cables is monitored. If the cable tension remains outside the set range for a long period of time, the device automatically tightens the cable and applies tension until it returns to a safe state. Subsequently, personnel can use wireless devices to collect and analyze data from the intelligent prestress loss control device for flexible photovoltaic support cables, construct a vibration model for the flexible photovoltaic support in the local environment, and modify the preset cable tension range based on actual operating conditions, thereby extending the service life of the flexible photovoltaic support and increasing photovoltaic power generation revenue.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific preferred embodiments.

[0033] In the description of the present invention, it should be understood that the terms "left side," "right side," "upper," "lower," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Terms such as "first" and "second" do not indicate the importance of components and therefore should not be construed as limitations on the present invention. The specific dimensions used in this embodiment are intended only to illustrate the technical solution and do not limit the scope of protection of the present invention.

[0034] Combine Figures 1 to 10The present invention provides a flexible photovoltaic bracket prestressed intelligent control device, including a shell 2, a protective shell 1 sleeved on the outside of the shell 2, the protective shell 1 is made of plastic material, the upper side of the shell 2 is a photovoltaic support plate 12 and an interface, the photovoltaic support plate 12 is used to hold the photovoltaic panel, receive solar energy, and provide energy for the flexible photovoltaic bracket cable prestressed intelligent control device, thereby realizing the energy consumption integration ecology of the device. There are three first interfaces 11 in the photovoltaic support plate 12 for connecting the photovoltaic panel with the main control board 3, which can transmit electrical energy and fix the photovoltaic panel. The protective shell 1 plays the role of protecting the internal device, the notch 15 facilitates the passage of the photovoltaic flexible cable 410, and the bolt hole 14 is used to pass the bolt 27 to fix it to the ground to ensure the stability of the overall structure.

[0035] The flexible photovoltaic bracket cable prestressed intelligent control device has a shell 2 that is made of high-strength steel material as a whole, and the upper part is a receiving cavity for placing the main control board 3. The provided protrusion 13 is adapted to the groove on the main control board 3, so that the main control board 3 can be directly embedded in the corresponding groove and fixed. The second interface 24 is used to transmit electrical energy and data. The fixed shaft 25 on the outside of the middle shell seat is the driving gear shaft 49. The shell 2 is used to protect the internal ratchet device and the cable winding structure. The through hole 22 is adapted to the shaft 49. The holes on both sides of the shaft 49 pass through the holes as a support seat for the rotation of the shaft 49. The lower part is the base, which is composed of 18 bolts 27 and a bottom plate 28 to form a secure connection, so that the device can withstand great tension. The internal fixed shaft 21 of the device is a two-way ratchet 45 shaft 49.

[0036] The main control board 3 is entirely made of aluminum alloy. The lower portion houses a rechargeable battery 36, which stores electricity and provides continuous power to the device when photovoltaic power generation efficiency is low. The center portion houses a connecting plate 35, which has a groove that mates with the protrusion 13 of the receiving cavity, facilitating the securement of the main control board 3 to the device. The upper portion comprises a LoRa wireless interface 31, a control MCU 32, a data storage unit 33, and a wireless transmission antenna 34. The pressure sensor 44 in the cable tension monitoring structure measures pressure and transmits the pressure monitoring data to the control MCU 32. The control MCU 32 filters the data, calculates pressure stability data, and transmits the data to the data storage unit 33. If the noise reduction data remains below a set safety range for an extended period, the control MCU 32 transmits a command to control the stepper motor 51 to rotate intermittently, for example, once per minute, each time by the distance of a ratchet tooth. The cable winding structure gradually tightens the photovoltaic prestressed flexible cable 410 until the pressure data monitored by the control MCU 32 returns to a preset safety range, at which point the stepper motor 51 stops. The control MCU 32 controls the LoRa wireless communication interface to transmit the stored data to an external receiving device via the wireless transmission antenna 34, thereby obtaining pressure data. Researchers can also process the monitoring data to analyze the health status of the flexible cable 410 and adjust the preset safety range of pressure based on actual conditions.

[0037] Because the photovoltaic flexible support cable 410 has a huge prestress, traditional winding cables are prone to failure. Therefore, this device adopts a ratchet structure, and the ratchet device is made of high-strength steel to prevent the winding structure from failing and causing structural damage. The ratchet device includes a pawl 48, a two-way pawl 45, a ratchet gear 46, a pawl fixing rod, a pawl rotating rod and a rotating shaft 49. The ratchet fixing rod 43 is fixed to the inner side of the shell seat through the fixed shaft 23 in the shell 2. The pawl 48 is constrained to rotate on the plane of the ratchet fixing rod 43 by the ratchet rotating rod 47. The center of the ratchet gear 46 and the ratchet fixing rod 43 is connected by the rotating shaft 49, and the ratchet gear 46 is fixed to the rotating shaft 49. When the stepper motor 51 rotates, the shaft 49 and the ratchet gear 46 can rotate clockwise normally. When the stepper motor 51 stops, under the tension of the flexible cable 410, the counterclockwise rotation of the shaft 49 that should have occurred is prevented by the ratchet 48, thereby achieving the unidirectional rotation of the shaft 49 and gradually tightening the cable 410. The alignment device is composed of a cable 410, an alignment wheel 41, and an alignment shaft 42. The alignment wheel 41 and the alignment shaft 42 are made of high-strength steel. The alignment shaft 42 is fixed to the housing 2, and the alignment wheel 41 is connected in series to the alignment shaft 42. The cable 410 passes between the upper and lower alignment wheels 41 to prevent the cable 410 from being worn due to friction with the notch 15 on the housing 2 and the protective shell 1 due to tilting.

[0038] The cable tension monitoring structure consists of a bidirectional pawl 45, a control MCU 32, and a pressure sensor 44. The bidirectional pawl 45 is made of high-strength steel, and the pressure sensor 44 is fixed to the housing 2. As the tension in the cable 410 gradually weakens, the force exerted by the ratchet gear 46 on the bidirectional pawl 45 gradually weakens, and the force exerted by the bidirectional pawl 45 on the pressure sensor 44 gradually weakens. Ultimately, the pressure monitored by the pressure sensor 44 gradually decreases. The monitoring data from the pressure sensor 44 is transmitted to the control MCU 32, which then determines whether the cable tension is within the safe setting range based on the pressure data, thus achieving the cable tension monitoring function.

[0039] The drive mechanism 5 consists of a driving gear, a driven gear 52, and a stepper motor 51. When the control MCU 32 detects that the cable tension value is chronically below a preset safety setting range, the stepper motor 51 is activated. The stepper motor 51 rotates intermittently, for example, once per minute, each time by one ratchet tooth. The cable winding mechanism gradually tightens the photovoltaic prestressed flexible cable 410 until the pressure data monitored by the control MCU 32 returns to a preset safety range. At this point, the stepper motor 51 stops, completing the prestress loss control function for the flexible photovoltaic support cable.

[0040] The above-mentioned flexible photovoltaic support prestressed intelligent control device is divided into five modules according to its functions: an energy device, a cable winding device 4, a cable force monitoring device, a driving device 5 and a data transmission device.

[0041] The energy device uses photovoltaic power generation or direct battery power to maintain a stable voltage. A photovoltaic panel is connected to the housing 2 to generate photovoltaic power. Current flows through a voltage regulator to power the device and charge the rechargeable battery 36. In poor weather conditions where photovoltaic power generation efficiency is low, the rechargeable battery 36 can provide auxiliary power to maintain long-term operation of the device.

[0042] The cable winding device 4 consists of a rotating shaft 49, a cable 410, two ratchet devices, two linear rotating shafts 42, and a linear wheel 41. One end of the photovoltaic cable 410 is embedded in the rotating shaft 49 and fixed to it, and is wound on the rotating shaft 49. The other end passes through the housing 2 to serve as a photovoltaic flexible bracket. The two sides of the rotating shaft 49 are fixed to the ratchet device to prevent the rotating shaft 49 from reversing. The linear rotating shaft 42 is fixed in the housing 2 to straighten the cable 410 and prevent it from rubbing against the housing 2. The four are tightly structured into a cable winding module to perform the work of tightening the photovoltaic cable 410.

[0043] The cable force monitoring device includes a ratchet, a two-way pawl 45, a pressure sensor 44 and a control MCU32. The ratchet is fixed to the rotating shaft 49. When the cable 410 is tightened, the ratchet gear 46 tends to rotate counterclockwise and interacts with the two-way pawl 45. The two-way pawl 45 tends to rotate clockwise and interacts with the pressure sensor 44. When the photovoltaic cable 410 is in a prestressed state, the force of the ratchet gear 46 on the two-way pawl 45 gradually decreases, and the pressure of the two-way pawl 45 on the pressure sensor 44 also decreases. The pressure sensor 44 transmits the monitored pressure data to the control MCU32. The control MCU32 performs noise reduction processing on the data and calculates the pressure stability data. When the pressure is lower than the preset range for a long time, the control MCU32 determines whether the photovoltaic cable 410 is in a prestressed state and realizes the cable force monitoring function. The calculation formula of the cable force detection module is as follows:

[0044] T=(4F N2 l0r / l2+4F N1 l0r / l1) / R (1)

[0045] Where, F N1 Indicates the measurement data of the left pressure sensor 44, F N2It represents the measurement data of the right pressure sensor 44, R represents the distance from the cable force to the center line of the rotating shaft 49, r represents the force arm of the ratchet exerted by the two-way pawl 45 to the center line of the rotating shaft 49, l1 represents the force exerted by the left ratchet on the two-way pawl 45 to the center force arm of the ratchet, l2 represents the force exerted by the right ratchet on the two-way pawl 45 to the center force arm of the ratchet, and l0 represents the force exerted by the pressure sensor 44 on the two-way pawl 45 to the center force arm of the ratchet.

[0046] The data noise reduction processing method comprises the following steps:

[0047] Step 1: Select the appropriate wavelet function and decomposition layer number N, and perform N-layer wavelet packet decomposition on the collected pressure data. According to the experimental results, the db5 wavelet and the wavelet packet decomposition layer number of 3 have the best denoising effect in actual engineering applications. For wavelet packet decomposition, let the wavelet packet coefficient at position (j, p) be The corresponding wavelet packet decomposition coefficients at the j+1th layer are as follows:

[0048]

[0049]

[0050] In the above formula, h(k) represents a low-pass filter, and g(k) represents a high-pass filter.

[0051] Step 2: Use a suitable threshold function to quantize each wavelet packet coefficient. According to the engineering results, the soft threshold function works best. At the same time, select sure as the threshold selection criterion, and the threshold T is set to Where n is the signal length;

[0052] Step 3: Based on the wavelet packet decomposition coefficients and the quantized coefficients, the signal is reconstructed by wavelet packet and the noise-removed signal is output. Wavelet packet coefficients at position (j, p) It can be reconstructed using the following formula:

[0053]

[0054] After obtaining the noise-reduced data, take one day as a time unit, remove the highest fifth and the lowest fifth of the data, and calculate the mean of the middle three fifths of the data as the pressure stabilization data.

[0055] The drive device 5 consists of a driving gear, a driven gear 52, a stepper motor 51, and a control MCU 32. The control MCU 32 determines whether the photovoltaic cable 410 has entered a prestress loss state by monitoring the pressure data. When the prestress loss of the cable exceeds the set range, the control MCU 32 controls the stepper motor 51 to operate, driving the driving gear and the driven gear 52 to rotate, thereby realizing the rotation of the rotating shaft 49, gradually tightening the photovoltaic cable 410 until the pressure data stabilizes within the preset safety range, achieving the prestress loss intelligent control function. The amount of cable 410 extension corresponding to one rotation of the driven gear 52 is:

[0056] Δ=n o πR / 12 (5)

[0057] where n o is the number of teeth of the driven gear 52, and R represents the distance from the cable to the center line of the rotating shaft 49.

[0058] The data transmission module consists of a data storage unit 33, a control MCU 32, a wireless transmission antenna 34, and a Lora wireless transmission interface. The data detected by the pressure sensor 44 is processed by the control MCU 32 and then transmitted to the data storage unit 33. Researchers can connect to the device through the Lora wireless transmission interface and the wireless transmission antenna 34 to collect data.

[0059] Before the device performs wireless transmission, it must first complete the network access operation. The specific operations are as follows:

[0060] Step 1: The computer sends a window opening instruction to allow the prestressed intelligent control device to access the network;

[0061] Step 2: The prestressed intelligent control device sends a network access request through the antenna, and the computer assigns a network address to the prestressed intelligent control device after receiving it;

[0062] Step 3: The computer obtains the information of the prestressed intelligent control device, and the processor numbers the prestressed intelligent control device connected to the network.

[0063] Wireless transmission device:

[0064] Step 1: The prestressed pressure intelligent control device performs real-time wavelet packet decomposition and noise reduction on the currently received pressure data signal, eliminating noise and storing the data locally. The highest and lowest fifths of the data are then removed, and the mean of the middle three-fifths is calculated and stored locally as the pressure steady-state data.

[0065] Step 2: The computer sends an AD reading instruction to the prestressed intelligent control device;

[0066] Step 3: The prestressed intelligent control device receives the computer instruction and sends a response message. After receiving the response message, the computer receives the data of the prestressed intelligent control device.

[0067] Step 4: The prestressed intelligent control device sends AD data via the Lora wireless transmission interface and the wireless transmission antenna 34, and the computer receives it;

[0068] Step 5: Select the next prestressed intelligent control device in the list and repeat the above steps.

[0069] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all fall within the scope of protection of the present invention.
