Description

Technical Field

[0001] The present invention belongs to the technical field of detection equipment, and in particular to a detection device and method for preventing a photovoltaic bracket from being deformed. Background Art

[0002] Photovoltaic equipment can convert light into electrical energy, but the current conversion efficiency of photovoltaic equipment is still low. Therefore, if you want to achieve power supply through photovoltaic equipment, you need to increase the construction scale of photovoltaic panels. Generally, in order to save construction costs, the brackets of large-scale photovoltaic equipment are spliced ​​through profiles, and then the photovoltaic panels are neatly laid on the brackets. Although this construction method is convenient and cost-saving, the brackets with spliced ​​structures are easily deformed by external forces such as wind and rain erosion and even ground subsidence, causing the bracket structure to be damaged and collapsed due to chain reactions. Therefore, it is very necessary to detect the brackets of photovoltaic equipment. The current detection methods of photovoltaic brackets are mainly focused on the detection of the brackets themselves. Due to the complex structure of the brackets and the large number of connection nodes, the labor cost of photovoltaic bracket detection is very high. Summary of the invention

[0003] In order to solve the problems existing in the prior art, the present invention provides a detection device and method for preventing photovoltaic bracket deformation, which solves the problems of cumbersome operation and high labor cost of the existing photovoltaic equipment bracket detection.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0006] The photovoltaic panel is laid on the photovoltaic bracket; the detector is symmetrically arranged on the photovoltaic panel;

[0007] The detector includes a mounting frame, a photoelectric sensor, a control board and a single-chip microcomputer. The mounting frame is set on the photovoltaic panel, the photoelectric sensor and the control board are both set on the mounting frame, the single-chip microcomputer is set on the control board, and the single-chip microcomputer and the control board are electrically connected; the output end of the photoelectric sensor is connected to the input end of the control board, and the probes of the photoelectric sensor are relatively set.

[0009] Furthermore, a boss is provided on the outer side surface of the threaded hole of the mounting frame, and the boss is cylindrical.

[0018] A detection method for preventing photovoltaic bracket deformation, based on any one of the above-mentioned detection devices for preventing photovoltaic bracket deformation, comprises the following process:

[0019] The photoelectric sensors are symmetrically arranged, one of which emits a laser signal and the other receives a laser signal. When the photovoltaic bracket is deformed, the position of the photoelectric sensor that emits the photoelectric signal or the position of the photoelectric sensor that receives the photoelectric signal shifts, generating signal feedback. The microcontroller processes the signal feedback and then transmits it.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] The present invention provides a detection device for preventing deformation of a photovoltaic bracket. Through symmetrically arranged photoelectric sensors, two photoelectric sensors form a comparison, one group is responsible for emitting lasers, and the other group is responsible for receiving. When the photovoltaic panels neatly laid in the same plane are warped, undulated or shifted, the laser signal of the photoelectric sensor is blocked or deviates from the original direction, thereby causing signal feedback. The single-chip microcomputer processes the feedback signal and transmits it. The detection device of the present invention utilizes the working principle of contrast photoelectrics, abandons the traditional method of directly detecting the photovoltaic bracket, and instead uses the method of detecting the position change of the photovoltaic panel group to identify the state of the photovoltaic bracket, which simplifies the requirements for the detection equipment and the demand for the manpower of the maintenance personnel, thereby improving the detection efficiency of the photovoltaic bracket. In addition, the device has a compact structure, a small appearance, is easy to operate, safe and reliable, and effectively solves the problems of cumbersome operation and high labor cost of the existing photovoltaic bracket detection.

[0022] Furthermore, by providing grooves and screws on the mounting frame, it is convenient to fix the mounting frame on the photovoltaic panel through the screws, so that the device can be quickly installed and debugged.

[0023] Furthermore, by arranging a boss on the outer side surface of the threaded hole of the mounting frame, the boss increases the threaded connection thickness between the screw rod and the mounting frame, thereby increasing the connection strength.

[0024] Furthermore, a protective shell is provided to protect the internal photoelectric sensor, control board and single-chip microcomputer, and a glass plate is provided at the front end of the probe of the photoelectric sensor to facilitate the transmission of the laser signal.

[0025] Furthermore, by setting up a Bluetooth module, when the photoelectric sensor detects deformation, the signal can be transmitted to the external control room to facilitate maintenance.

[0026] Furthermore, the power is supplied by a backup battery, and the photoelectric sensor and the control panel are electrically connected to the photovoltaic panel. During the day, the detector is powered by the photovoltaic panel, while at night it is powered by the backup battery, thereby increasing the application range of the detection device and saving energy.

[0034] Reference Figure 1-3 A detection device for preventing a photovoltaic bracket from deforming includes a photovoltaic bracket 1, a photovoltaic panel 2 and a detector 3. The photovoltaic panel 2 is laid on the top of the photovoltaic bracket 1, and the detectors 3 are symmetrically distributed at both ends of the photovoltaic panel 2.

[0035] The detector 3 includes a mounting frame 4, a photoelectric sensor 11, a control board 13, a single-chip computer 14, a Bluetooth module 15 and a backup battery 16. The cross-sectional profile of the mounting frame 4 is in an inverted concave shape, and the mounting frame 4 is sleeved with one end of the photovoltaic panel 2. A boss 402 is provided at the bottom end of the mounting frame 4, and the boss 402 is cylindrical; a threaded hole 401 is provided at the bottom end of the boss 402 along its axial direction, and the threaded hole 401 passes through the bottom end of the mounting frame 4, and a screw rod 5 is connected to the inner thread of the threaded hole 401, and the bottom end of the screw rod 5 is fixedly connected to a handle 7, and the top end of the screw rod 5 is fixedly connected to a circular plate 6, and the circular plate 6 is located at the bottom end of the photovoltaic panel 2, and a protective shell 8 is matched with the top end of the mounting frame 4, and the photoelectric sensor 11, the control board 13 and the backup battery 16 are both sleeved in the protective shell 8, and the side wall of the protective shell 8 is matched with a glass plate 9 at the transmitting end of the photoelectric sensor 11. The top of the mounting frame 4 is fixedly connected with a bracket 10, and the bracket 10 is perpendicular to the mounting frame 4. The photoelectric sensor 11 is fixedly sleeved with the bracket 10. The top of the mounting frame 4 is provided with a partition 12, and the partition 12 is perpendicular to the mounting frame 4. The control board 13 is arranged on the side of the partition 12 away from the photoelectric sensor 11, and a single-chip microcomputer 14 and a Bluetooth module 15 are arranged on one side of the control board 13. The backup battery 16 is arranged on the side of the control board 13 away from the partition 12. The photovoltaic panel 2, the backup battery 16, the control board 13 and the photoelectric sensor 11 are electrically connected. The reference model of the photoelectric sensor 11 of the device on the market is LTT-12NOT.

[0036] The present invention provides a detection method for preventing photovoltaic bracket deformation, which includes the following process: the photoelectric sensors 11 are contrast photoelectric sensors, that is, one group is responsible for emitting laser and the other group is responsible for receiving. When the laser deviates from the photoelectric sensor 11 of the receiving group, a signal feedback is generated.

[0037] The device needs to set up two groups of detectors 3 at the two ends of the photovoltaic panel 2. The photoelectric sensors 11 in the two groups of detectors 3 are respectively one group receiving the emission of the other group. The detectors 3 are clamped at the two ends of the photovoltaic panel 2 through the mounting frame 4, and the screw 5 is driven to screw in by rotating the handle 7 to squeeze the circular plate 6 on the back of the photovoltaic panel 2, so that the detectors 3 can be fixed to the photovoltaic panel 2, and the angles of the detectors 3 are adjusted so that the photoelectric sensors 11 in the two groups of detectors 3 are aligned with each other through the glass plate 9.

[0038] When the supporting structure of the photovoltaic bracket 1 is obviously deformed, the most direct manifestation is that the photovoltaic panels 2 that were originally laid neatly in the same plane will appear warped, undulated or shifted. As a result, the laser signal of the photoelectric sensor 11 will be blocked or deviate from its original direction, thereby causing signal feedback. After the control board 13 processes the signal through the single-chip microcomputer 14, the Bluetooth module 15 transmits the alarm signal to the control room. The power supply of the detector 3 is provided by the photovoltaic panel 2 during the day and by the backup battery 16 at night.
