Problems solved by technology

[0002] Photovoltaic power generation or photothermal utilization projects can be seen everywhere in my country nowadays, but photovoltaic panels or photothermal heat-absorbing equipment are exposed to the outside all year round. When there is heavy snow in winter, snow will accumulate on the panels, which seriously affects power generation. efficiency
[0003] At present, most of the snow cleaning work for photovoltaic panels adopts manual snow shoveling and cleaning, and then uses water guns to clean the cleaning work. This is not only time-consuming and laborious, but also cannot clean photovoltaic panels in time, which affects power generation efficiency.

Embodiment 1

[0041] The initial position of the laser transmitter 8 and the laser receiver 10 is 0.1mm-10mm higher than the upper surface of the photovoltaic panel 1, and the signal of whether there is an obstacle between the laser transmitter 8 and the laser receiver 10 is obtained every set time, if When an obstacle signal is received, the snow removal function is activated.

Embodiment 2

[0043] 1) The initial position of the laser transmitter 8 and the laser receiver 10 is 0.5mm-10mm higher than the upper surface of the photovoltaic panel 1, and the laser transmitter 8 and the laser receiver 10 are pushed along the photovoltaic panel 1 by tilting the hydraulic cylinder 11 every set time. The side reciprocates once, if there is an obstacle between the laser transmitter 8 and the laser receiver 10 during the reciprocating movement, then perform the next step;

[0044] 2) Whether the vertical hydraulic cylinder 12 has risen to the top, if so, perform step 5), otherwise the vertical hydraulic cylinder 12 has risen to a set distance;

[0045] 3) Incline the hydraulic cylinder 11 to push the laser transmitter 8 and the laser receiver 10 to reciprocate once along the side of the photovoltaic panel 1, and return to 2) if there is an obstacle between the laser transmitter 8 and the laser receiver 10, otherwise perform the following step;

[0046] 4) Keep the current s...

Abstract

A snow removal system for a photovoltaic photothermal device is provided with at least one inclined fixed photovoltaic plate, the upper eaves of each photovoltaic panel are fixedly provided with a cleaning branch pipe arranged horizontally, Each cleaning branch pipe is uniformly provided with a hole for spraying water on the upper surface of the photovoltaic panel, and each cleaning branch pipe iscommunicated with a water supply main pipe, the water inlet end of the water supply main pipe is connected with the outlet of a three-way electromagnetic valve, one of the inlets of the three-way electromagnetic valve is connected with a water pump, and the water pump is installed in a hot water tank and pumps water to the water supply main pipe. The snow removing system of the invention can automatically identify the snow cover condition and intelligently select an appropriate time for snow removing, the operation is stable and reliable, energy is saved and environmental protection is ensured, and the work efficiency of the photovoltaic photothermal device is ensured.

Description

technical field [0001] The invention relates to the field of photovoltaics, in particular to a cleaning system for photovoltaic panels. Background technique [0002] Photovoltaic power generation or photothermal utilization projects can be seen everywhere in my country nowadays, but photovoltaic panels or photothermal heat-absorbing equipment are exposed to the outside all year round. When there is heavy snow in winter, snow will accumulate on the panels, which seriously affects power generation. efficiency. [0003] At present, most of the snow cleaning work for photovoltaic panels adopts manual snow shoveling and cleaning, and then uses water guns to complete the cleaning work. This is not only time-consuming and laborious, but also cannot clean photovoltaic panels in time, which affects power generation efficiency. Contents of the invention [0004] The technical problem to be solved by the present invention is to realize a snow removal system capable of automatically c...
