Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic power station status monitoring, and more specifically, to a wireless-based photovoltaic power station status monitoring device. Background Art

[0002] Photovoltaic power station refers to a photovoltaic power generation system that uses solar energy and special materials such as crystalline silicon panels, inverters and other electronic components to connect to the power grid and transmit electricity to the grid. In recent years, the construction of photovoltaic power stations is mostly distributed in desert areas, and remote monitoring technology is used to reduce the operating costs and risks of photovoltaic power generation systems.

[0003] Installing environmental monitoring devices near photovoltaic power stations can monitor the environmental parameters around the photovoltaic power stations in real time, such as temperature, humidity, wind speed, wind direction, irradiance (or light intensity), etc. These parameters are crucial for evaluating the power generation potential of photovoltaic systems. For example, changes in irradiance will directly affect the power generation of photovoltaic panels, while temperature will affect the conversion efficiency of the panels. By monitoring these data in real time, operation and maintenance personnel can adjust the operating status of the photovoltaic system in a timely manner to optimize power generation efficiency.

[0004] Since desert areas often have strong winds, desert sand is driven by the wind to hit the surface of the bracket where the environmental monitoring equipment is installed, causing wear on the bracket surface. Long-term wear can easily cause scratches on the bracket surface and cause the anti-rust coating on the bracket surface to fall off, causing the metal substrate of the bracket to be directly exposed to wind, sand and harsh climate, which will accelerate the corrosion of the bracket and thereby reduce the structural strength and stability of the bracket.

[0005] Currently, the monitoring of the wear condition of the anti-rust layer on the surface of the above-mentioned bracket is usually achieved by regular (annual or quarterly, etc.) manual inspection. Manual inspection requires a lot of time and energy, so the inspection frequency is often limited, which means that the wear condition may not be discovered in time, causing the problem to worsen or miss the best time for repair.

[0032] One or more technical solutions provided in the technical solution of this application have at least the following technical effects or advantages:

[0033] 1. The present application is capable of tracking and monitoring the degree of wear of the anti-rust layer attached to the surface of the supporting bracket by means of an execution tracking unit disposed in the sample groove on the side wall of the supporting bracket. When the anti-rust layer attached to the blocking component of the execution tracking unit with the same thickness as the anti-rust layer on the surface of the supporting bracket is worn, the environmental water vapor enters the execution tracking unit through the blocking component and triggers the alarm unit to send a wear warning signal.

[0034] 2. Place the execution tracking unit into the sample slot. When the end of the execution tracking unit contacts the first chamfered transition portion on the end of the clamping head seat, as the depth of the execution tracking unit entering the sample slot continues to increase, the execution tracking unit continuously pushes the clamping head seat into the buckle slide slot through the first chamfered transition portion. When the polygonal positioning protrusion is inserted into the polygonal positioning groove on the bottom wall of the sample slot, the clamping head seat on the side wall of the sample slot is aligned with the locking hole on the side wall of the outer cylinder shell. Then, under the action of the first spring force, the clamping head seat is quickly buckled into the locking hole, thereby facilitating the operator to install the execution tracking unit on the supporting bracket.

[0035] 3. When the anti-rust layer with the same thickness as the anti-rust layer on the surface of the supporting bracket attached to the arresting component of the execution tracking unit is worn, the environmental water vapor enters the interior of the execution tracking unit through the waterproof and breathable membrane in the arresting component and is continuously absorbed by the hygroscopic and swollen particles. The hygroscopic and swollen particles whose volume expands due to absorbing water continuously squeeze the inner ring wall of the annular elastic airbag, causing the internal air pressure of the annular elastic airbag to continuously increase, causing the outer ring wall of the annular elastic airbag to elastically deform outward and drive the transmission slide to slide. During the sliding process, the transmission slide contacts the second chamfered transition portion in the alarm unit, and drives the trigger spring to contact the fixed terminal through the second chamfered transition portion, thereby triggering the control circuit board to control the wireless signal transmitter to send a wear warning signal to the external main controller, thereby tracking and monitoring the wear degree of the anti-rust layer attached to the surface of the supporting bracket, and reminding the staff that the anti-rust layer on the surface of the supporting bracket has been worn, and it is necessary to promptly inspect it and repair the worn anti-rust layer on its surface. Through timely repair, the damage to the supporting bracket structure caused by subsequent rust can be effectively reduced, thereby extending its service life.

[0036] 4. The anti-rust layer attached to the arresting component is worn, allowing environmental water vapor to penetrate the arresting component and enter the interior of the execution tracking unit. In the process of the hygroscopic particles that expand in volume due to water absorption driving the outer ring wall of the annular elastic airbag to undergo elastic deformation, not only can the trigger spring in the alarm unit be driven to contact the fixed terminal through the transmission slide, but the release rod can also be driven to push the clamping head seat that is buckled into the locking hole out of the locking hole, thereby facilitating the operator to remove the failed execution tracking unit from the supporting bracket, thereby shortening the maintenance time of the bracket and improving the maintenance efficiency of the bracket.

[0037] 5. After the tracking unit is taken out from the sample tank, the operator rotates the arresting assembly. When the side wing limit seat in the arresting assembly is aligned with the inlet and outlet on the outer cylinder shell, the tracking unit is inverted. Under the action of gravity, the arresting assembly falls off the outer cylinder shell. Then the tracking unit is inverted again, so that the annular elastic airbag slides out of the inner cavity of the outer cylinder shell, and the ineffective hygroscopic and expanded particles are poured out from the space surrounded by the annular elastic airbag and the interception net. Then, new hygroscopic and expanded particles are refilled into the inner cavity of the annular elastic airbag, and the annular elastic airbag is put back into the inverted The wing limit seat in the new arresting assembly is placed into the inner cavity of the outer cylinder shell, and then the annular outer frame squeezes the surface of the annular elastic airbag. The arresting assembly is then rotated to stagger the wing limit seat and the entrance and exit, and the arresting assembly newly installed at the opening of the end of the outer cylinder shell is clamped and fixed under the elastic force of the annular elastic airbag, so that the operator can remove the execution tracking unit from the supporting bracket and only replace the failed arresting assembly and hygroscopic expanded particles. There is no need to replace the execution tracking unit as a whole, thereby reducing the maintenance cost of the supporting bracket. BRIEF DESCRIPTION OF THE DRAWINGS

[0084] After the tracking unit is taken out from the sample tank, the operator rotates the blocking assembly. When the side wing limit seat 117 in the blocking assembly is aligned with the entrance and exit on the outer cylinder shell 103, the tracking unit is inverted. Under the action of gravity, the blocking assembly falls off the outer cylinder shell 103, and then the tracking unit is inverted again, so that the annular elastic airbag 108 slides out of the inner cavity of the outer cylinder shell 103, and the failed hygroscopic and expanded particles 107 are poured out from the space surrounded by the annular elastic airbag 108 and the interception net 106, and then the new hygroscopic and expanded particles 107 are refilled into the inner cavity of the annular elastic airbag 108, and the annular elastic airbag 108 is put back into the inverted The wing limit seat 117 in the new arresting assembly is placed in the inner cavity of the outer cylinder shell 103, and then the annular outer frame 102 squeezes the surface of the annular elastic airbag 108. The arresting assembly is then rotated to stagger the wing limit seat 117 and the entrance and exit, and the arresting assembly newly installed at the end opening of the outer cylinder shell 103 is clamped and fixed under the elastic force of the annular elastic airbag 108, so that the operator can remove the execution tracking unit from the supporting bracket 101 and only replace the failed arresting assembly and the hygroscopic expanded particles 107, without replacing the execution tracking unit as a whole, thereby reducing the maintenance cost of the supporting bracket 101.
