Description

Technical Field

[0001] The present invention relates to the technical field of intelligent information collection equipment, in particular to an intelligent information collection equipment based on photovoltaic data. Background Art

[0002] As solar photovoltaic power generation technology continues to mature and become more popular, data acquisition and remote monitoring are becoming increasingly important, and energy data visualization and transparency are also standards that everyone is concerned about every day. Solar photovoltaic power generation is gradually shifting from special applications to more general civilian use, and from auxiliary energy to basic energy. At the same time, as photovoltaic installed capacity continues to increase and the market continues to saturate, people are beginning to pay more and more attention to power generation, and extensive power station operation and maintenance management will inevitably gradually transform into refined power station operation and maintenance management.

[0003] Photovoltaic power stations are mainly installed in places with abundant sunshine to maximize the capture of solar energy, such as plains, mountains, deserts and other areas. This makes them generally located in relatively remote places, and going to the site often consumes a lot of time and manpower costs. Therefore, in order to monitor the operating status of photovoltaic (grid-connected) power station equipment in real time and ensure that the equipment and devices can operate normally, the power station is usually equipped with a photovoltaic data collector, which collects the voltage, current, power, temperature, irradiance, etc. of the photovoltaic equipment when it is working, and transmits it to the database device to improve the safety of power station operation and the efficiency of operation and maintenance management, and increase power generation income and asset value.

[0004] Photovoltaic equipment may be blocked during use, and the blocked part cannot work properly, causing the temperature of the covered part to rise much higher than that of the uncovered part, resulting in the appearance of burnt dark spots due to excessive temperature. The hot spot effect will reduce the output power of the component to a certain extent. If the heating temperature exceeds a certain limit, it will cause permanent damage such as partial burning of the photovoltaic component to form dark spots, melting of solder joints, aging of packaging materials, etc., which is an important factor affecting the output power and service life of photovoltaic components. Therefore, it is very necessary to accurately monitor the temperature of the photovoltaic panel surface to avoid the formation of hot spots.

[0005] 1. Obstructions will affect the detection of temperature data, causing inaccurate temperature detection, thereby affecting the collection of photovoltaic data information. The obstruction of photovoltaic panels may be caused by dust, leaves, bird droppings, etc. Since photovoltaic panels are installed in relatively remote areas, it often takes a lot of time and manpower to go to the site, making it inconvenient to clean them. Moreover, some obstructions can be cleared by sweeping. If obstructions that can be easily cleared are cleaned manually, it will lead to an increase in labor costs.

[0006] 2. Currently, photovoltaic panels are monitored by attaching contact temperature sensors to the back of the photovoltaic panels to detect temperature. However, this method of detecting temperature can only detect fixed areas of the photovoltaic panels. When the heating point is too far away from the monitoring point, the temperature of the entire area cannot be monitored, and inadequate detection may occur. When there are too many photovoltaic panels, the demand for contact temperature detectors is too high, thereby increasing production input costs.

[0007] 3. The dust on the photovoltaic panels will not only affect the conversion efficiency of the photovoltaic panels, but also the dust adsorbed on the photovoltaic components is mostly acidic or alkaline. In addition, the dust has strong adsorption capacity. After a period of time, the surface of the photovoltaic panel will gradually corrode and be damaged under the erosion of the acidic or alkaline environment, making the surface bumpy, resulting in the attenuation of the optical performance of the photovoltaic panel, lower efficiency, less power generation, and shortened component life. Even if a cleaning device is used to clean the dust and bird droppings on the photovoltaic panels, the cleaned dust will fall on other photovoltaic panels again, affecting other photovoltaic panels. It is only a temporary solution and not conducive to long-term use.

[0008] The Chinese patent with the authorization announcement number CN110542478A discloses a photovoltaic data collector, which includes a controller, a photosensitive receiving body, a photosensitive array and a driving bracket; the photosensitive receiving body includes a fan-shaped receiving unit, and two adjacent fan-shaped receiving units are connected by a deformable flexible connector; the fan-shaped receiving unit is provided with a photosensitive array for collecting light sources and outputting environmental illumination information; the driving bracket includes a driving mechanism corresponding to the photosensitive receiving body, the driving mechanism includes a fixing part and a driving part, and the driving part includes a supporting part and a driving part; the controller includes an illumination collection module for receiving environmental illumination information and a collection driving module for outputting a collection driving instruction and driving the driving mechanism to work. The disadvantage of the device is that each fan-shaped receiving unit is fixed by a driving mechanism, and the direction of each fan-shaped receiving unit toward the sun is fixed. Since photovoltaic panels are generally installed in relatively remote places, the local environment is harsh, and the fan-shaped receiving unit may be damaged, which will affect the accuracy of power station data collection, and each fan-shaped receiving unit has a separate driving mechanism at the bottom, which makes the manufacturing cost high and is not conducive to large-scale use.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the embodiments described are only part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0040] Depend on Figures 1 to 11 The invention provides a mobile mechanism 101 and an information collection mechanism 102 located on the mobile mechanism 101. The track 132 on the mobile mechanism 101 is installed on the photovoltaic panel. By being arranged in parallel with the photovoltaic panel, the crossbeam 131 is driven to move horizontally, thereby increasing the detection area. The mobile mechanism 101 is arranged on the photovoltaic panel. The information collection mechanism 102 includes a mobile frame 103 and a temperature collector 104. The temperature collector 104 is a non-contact infrared sensor. The closer the distance to the photovoltaic panel is, the higher the detection accuracy is. When the air pressure in the airbag 106 increases, the mobile plate 113 drives the temperature collector 104 to extend out from the compression chamber 112, thereby detecting the temperature of the photovoltaic panel. Although it is very close to the photovoltaic panel, it does not contact the photovoltaic panel. When the air pressure in the airbag 106 decreases, the compression spring 114 is reset, and the temperature collector 104 is pulled back into the compression chamber 112. The compression chamber 112 is isolated from the outside world by a self-closing rubber sealing cover 115, thereby protecting the temperature collector 104.

[0041] refer to Figures 3 to 10 The bottom end of the mobile frame 103 is fixedly connected with an air pump device 105, the air outlet of the air pump device 105 is at the bottom and is arranged in the air bag 106. By continuously inflating the air bag 106, the air bag 106 is expanded. The bottom end of the air pump device 105 is fixedly connected with the air bag 106, and the bottom end of the air bag 106 is fixedly connected with a lifting plate 107. The air bag 106 is fixedly connected with a spring keel 108. The two ends of the spring keel 108 are fixedly connected to the lifting plate 107 and the air pump device 105. When the air pressure inside the air bag 106 increases, the air bag 106 will move. The spring keel 108 is stretched longitudinally, and when there is no air pressure inside the airbag 106, the spring keel 108 drives the airbag 106 to reset. The inner ring surface of the lifting plate 107 is fixedly connected with a connecting rod 109 with a hollow structure, and one end of the connecting rod 109 is fixedly connected with an annular tube 110. The inner wall of the annular tube 110 is fixedly connected with a fixing ring 111. The inner wall of the annular tube 110 and the top of the fixing ring 111 are provided with a compression chamber 112. The temperature collector 104 is located in the compression chamber 112. The top of the compression chamber 112 is a moving plate 113, and the bottom is a rubber seal. The sealing cover 115 can be isolated from the outside air. When the pressure in the airbag 106 increases, the movable plate 113 in the compression chamber 112 moves downward, thereby pushing the temperature collector 104 out of the compression chamber 112. The movable plate 113 is slidably connected in the compression chamber 112. The temperature collector 104 is located at the bottom end of the movable plate 113. A compression spring 114 is provided between the fixed ring 111 and the movable plate 113. The compression spring 114 is sleeved on the temperature collector 104. The bottom end of the fixed plate is fixedly connected with a rubber sealing cover 115. The rubber sealing cover 115 is made of It is made of rubber, and the bottom is in a closed petal shape, which plays a sealing role. It can be pushed open from the top downward. After being pushed open, it can be restored due to the characteristics of rubber. When the temperature collector 104 moves downward, the rubber sealing cover 115 will be pushed open. When the temperature collector 104 retracts into the compression chamber 112, the rubber sealing cover 115 can automatically close to isolate the outside air from the temperature collector 104, thereby protecting the temperature collector 104. A beveled collar 116 for pushing the rubber sealing cover 115 open is fixedly connected to the outer wall of the collector;

[0042] refer to Figures 5 to 10An upper rotating disk 117 and a lower rotating disk 118 are rotatably connected between the inner annular surface of the lifting disk 107 and the outer annular surface of the annular tube 110. A guide vane 119 arranged toward the annular tube 110 is fixedly connected between the upper rotating disk 117 and the lower rotating disk 118. When the airflow blows from the airflow disk 123 to the guide vane 119, the guide vane 119 is pushed by the airflow, driving the upper rotating disk 117, the lower rotating disk 118 and the cleaning brush 120 to rotate. The bottom end of the lower rotating disk 118 is fixedly connected with a cleaning brush 120. After the airflow pushes the guide vane 119 to rotate, the airflow enters the bottom of the lower rotating disk 118 from the vent hole 122 in the center of the lower rotating disk 118, carrying the water sprayed by the water mist nozzle 124. The mist moves toward the cleaning brush 120, and part of the airflow flows out from the airflow groove 121 provided on the cleaning brush 120. The bottom end of the cleaning brush 120 is provided with an arc-shaped airflow groove 121, and the lower rotating disk 118 is provided with vents 122 evenly distributed along the annular tube 110. An airflow disk 123 is fixedly connected to the inner annular surface of the lifting disk 107, and a water mist nozzle 124 is fixedly connected to the bottom end of the annular tube 110. The water mist nozzle 124 can spray water mist. By controlling the size of the sprayed water mist, the wetness of the cleaning brush 120 is controlled. When the cleaning brush 120 is cleaning on the photovoltaic panel, the water mist nozzle 124 can be disabled and only used for cleaning. The spray hole of the water mist nozzle 124 is set toward the cleaning brush 120;

[0043] refer to Figure 5 , Figure 8 and Fig. 9 , a plurality of hollow connecting tubes 125 arranged along the axis of the annular tube 110 are fixedly connected in the compression chamber 112, and the connecting tubes 125 are hollow and used for the passage of air and water. An air inlet hole 126 is opened on the outer wall of one of the connecting tubes 125, and the air inlet hole 126 is connected with the air flow disk 123 through the connecting tube 125 and the connecting rod 109 to form an air flow channel. When the movable plate 113 moves downward, the air inlet hole 126 on the connecting tube 125 will be exposed, and the air flow enters through the air inlet hole 126, moves to the air flow disk 123 after passing through the connecting tube 125 and the connecting rod 109, and then sprays out from the air flow disk 123, pushing the guide blade 119 to rotate, and another connecting tube 125 and the water mist nozzle 124 are connected to the external water supply end, and the water mist nozzle 124 is connected to the external water supply end through another connecting tube 125, so that water mist can be sprayed to moisten the cleaning brush 120 to form a water flow channel.

[0044] Specifically, refer to Figure 3 and Figure 4The two sides of the lifting plate 107 are symmetrically fixedly connected with connecting frames 127, and the top of the connecting frames 127 is fixedly connected with guide columns 128. The lifting plate 107 is stably raised and lowered through the guide columns 128. The guide columns 128 are slidably connected to the moving frame 103. The top of the moving frame 103 is fixedly connected with a U-shaped frame 129. The light intensity detection device 130 at the top of the U-shaped frame 129 can detect the light intensity at the temperature detection position to determine whether the detection point is blocked by foreign objects. The light intensity detection device 130 is installed on the top of the U-shaped frame 129.

[0045] Specifically, refer to Fig.11 The mobile mechanism 101 includes a beam 131 and a track 132. A threaded rod 133 is rotatably connected inside the beam 131. The threaded rod 133 is transmission-connected to the mobile frame 103. A driving motor 134 is installed at one end of the beam 131. When the information collection mechanism 102 measures the temperature of the photovoltaic panel, the driving motor 134 and the threaded rod 133 can push the mobile frame 103 to move back and forth on the beam 131. The output end of the driving motor 134 is fixedly connected to the threaded rod 133.

[0046] Specifically, refer to Fig.11 and Fig.12 The bottom of both ends of the crossbeam 131 is fixedly connected with a driving vehicle 135. The driving vehicle 135 moves laterally on the track 132 through the hub motor 136. The stabilizing wheels 137 on both sides maintain the stable movement of the driving vehicle 135 to prevent derailment. The bottom end of the driving vehicle 135 is fixedly connected with the hub motor 136 and the stabilizing wheel 137. The hub motor 136 is located between the symmetrical stabilizing wheels 137. The stabilizing wheels 137 are rotatably connected to the grooves on both sides of the track 132.

[0047] Specifically, refer to Fig.12 and Fig.13A water tank bracket 138 is fixedly connected to the driving vehicle 135 at one end, and a water storage tank 139 is fixedly connected to the water tank bracket 138. When the lifting plate 107 covers the water storage tank 139, a sealed chamber is formed, and the internal air flow is discharged from the drain pipe. A retaining edge 140 is fixedly connected to the top of the water storage tank 139, and a water guide plate 141 is fixedly connected to the inner ring surface of the water storage tank 139. A tooth claw frame 142 and a water ring 143 are fixedly connected to the top of the water guide plate 141. The outer wall of the water ring 143 is provided with a useful The center of the water guide plate 141 is inclined toward the water ring 143, and the top of the water ring 143 is fixedly connected to a rubber ring 145 that cooperates with the water mist nozzle 124. The rubber ring 145 cooperates with the water mist nozzle 124, and when connected to each other, they can protect the temperature collector 104 to prevent water mist from entering the rubber ring 145 when the cleaning brush 120 is cleaned by water mist, thereby affecting the temperature collector 104. A drain pipe is installed on the outer wall of the water storage tank 139.

[0048] Specifically, refer to Fig.14 The claw frame 142 is evenly arranged along the axis of the water ring 143, and a plurality of oblique claws 146 are arranged on the claw frame 142. When the cleaning brush 120 rotates on the water guide plate 141, the claw frame 142 will clean the cleaning brush 120 and remove foreign matter adhered to the cleaning brush 120. When the cleaning brush 120 moves, the bristles will move from the bottom end to the top end of the inclined surface 147. By moving from coarse to fine, the sewage in the cleaning brush 120 can be squeezed out, so that the sewage flows into the water storage tank 139. The setting direction of the oblique claws 146 is opposite to the rotation direction of the cleaning brush 120, and an inclined surface 147 is arranged between adjacent oblique claws 146.

[0049] When the present invention is in use, the track 132 of the mobile mechanism 101 is fixed to the two ends of the photovoltaic panel, so that the mobile mechanism 101 can move laterally along the track 132 parallel to the photovoltaic panel, and the two ends of the crossbeam 131 are fixed to the driving vehicle 135. The driving vehicle 135 moves on the track 132 through the bottom hub motor 136. The stabilizing wheels 137 are located in the grooves on both sides of the track 132 to prevent the driving vehicle 135 from derailing when moving. The crossbeam 131 is internally installed with a driving motor 134 and a threaded rod 133. The output end of the driving motor 134 pushes the information collection mechanism 102 to move in the vertical direction through the threaded rod 133, so that the temperature of the photovoltaic panel is linearly detected by the temperature collector 104.

[0050] When it is necessary to perform large-area and accurate temperature detection on the photovoltaic panel, the drive motor 134 is started to move the information collection mechanism 102 to one side of the photovoltaic panel, and the air pump device 105 at the bottom of the mobile frame 103 is started to pump air into the airbag 106 at the bottom. The airbag 106 expands, driving the spring keel 108 to stretch together, and the lifting plate 107 moves toward the photovoltaic panel as the airbag 106 stretches, so that the cleaning brush 120 at the bottom is closely attached to the photovoltaic panel, and the air pump device 105 continues to increase the airflow in the airbag 106, the pressure inside the airbag 106 increases, and the airbag in the compression chamber 112 is compressed. The movable plate 113 is acted upon by the air pressure at the top and moves downward, so that the movable plate 113 drives the temperature collector 104 to move downward, and the compression spring 114 at the bottom is compressed. When the temperature collector 104 moves downward, it comes into contact with the rubber sealing cover 115, and the rubber sealing cover 115 is pushed open by the bevel ring 116, so that the temperature collector 104 extends out of the compression chamber 112 and moves toward the photovoltaic panel, and detects the temperature on the surface of the photovoltaic panel, but does not contact the photovoltaic panel. The temperature collector 104 uses an infrared sensor, and the closer the distance to the photovoltaic panel is, the higher the detection accuracy is;

[0051] When there is dust on the photovoltaic panel or an obstruction that affects temperature detection, the movable plate 113 moves toward the fixed ring 111, and the compression spring 114 is compressed, so that the air inlet 126 on one of the connecting tubes 125 is exposed, and the air inlet 126 forms an air flow channel with the air flow disk 123 through the connecting tube 125 and the connecting rod 109. The air enters from the air inlet 126 on the connecting tube 125, passes through the connecting tube 125 and the connecting rod 109, and is ejected from the air flow disk 123 on the inner ring surface of the annular tube 110. The ejected airflow hits the guide vane 119 between the upper rotating disk 117 and the lower rotating disk 118, thereby pushing the guide vane 119 to rotate, so that the lower rotating disk 118 and the cleaning brush 120 at the bottom rotate together, thereby The obstructions on the photovoltaic panel are cleaned, and the water mist nozzle 124 is started to spray water mist. After the airflow passes through the guide blade 119, it moves from the vent 122 on the lower rotating disk 118 to the bottom of the lower rotating disk 118, and combines with the water mist sprayed by the water mist nozzle 124. The airflow wrapped in the water mist will moisten the cleaning brush 120, thereby increasing the cleaning ability of the cleaning brush 120, and the obstructions such as bird droppings hardened on the photovoltaic panel are cleaned, so that the area at the bottom of the information collection mechanism 102 is cleaned, so as to accurately measure the temperature. The light intensity detection device 130 on the top of the mobile frame 103 can detect the light intensity of the temperature detection area, so as to judge whether the decrease in photovoltaic panel power conversion is caused by foreign objects blocking;

[0052] It should be noted that the water mist nozzle 124 is very close to the photovoltaic panel, but not in contact with it, and an air flow slot 121 is provided at the bottom of the cleaning brush 120 for discharging air flow, so that the water mist will flow out of the air flow slot 121 along with the air flow, and will not affect the temperature collector 104. After the obstruction is cleared, the information collection mechanism 102 is driven by the drive motor 134 to move in the vertical direction, so as to perform linear temperature detection and measure the temperature of the cleaned area. When the temperature of the entire photovoltaic panel needs to be detected, the temperature of a large area is detected by the lateral movement of the driving vehicle 135. It should be noted that the water mist nozzle 124 is not necessarily used when cleaning the photovoltaic panel. The water mist nozzle 124 is used here when the photovoltaic panel is located in an arid and water-scarce area and the surface of the photovoltaic panel is blocked by wind and sand, which affects the temperature detection and the power generation efficiency of the photovoltaic panel.

[0053] When cleaning in dusty areas, the cleaning brush 120 gets dirty quickly. Failure to clean it will affect the subsequent cleaning ability and reduce the subsequent temperature detection ability. A water storage tank 139 is fixed to one side of the crossbeam 131 through a water tank bracket 138. The information collection mechanism 102 moves to the top of the water storage tank 139 and inflates the airbag 106, so that the lifting plate 107 covers the top of the water storage tank 139 and contacts the retaining edge 140 to form a sealed chamber. The airbag 106 is continuously pressurized to make the cleaning brush 120 rotate on the top of the water guide plate 141. The water mist nozzle 124 covers the rubber ring 145 to protect the internal temperature collector 104. The water mist nozzle 124 continuously sprays water mist to clean the cleaning brush 120. During washing, the cleaning brush 120 contacts the tooth claw frame 142 on the top of the water guide plate 141 and rotates continuously. The oblique tooth claws 146 on the tooth claw frame 142 scrape off the debris on the cleaning brush 120, and the bristles on the cleaning brush 120 sweep between adjacent oblique tooth claws 146 and move from the bottom to the upper part of the inclined surface 147, so that the bristles are squeezed to squeeze out the sewage between the brushes. The sewage falls on the water guide plate 141, flows to the water ring 143 through the inclination angle of the water guide plate 141, and flows into the water storage tank 139 at the bottom through the water holes 144 on the water ring 143. The drain pipe on the water storage tank 139 is set at a certain height, and the mud and sand in the sewage sink, and the sewage on the top of the water surface is discharged from the drain pipe, and the airflow in the water storage tank 139 is discharged from the drain pipe together.

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
