With the development of robot technology, robots have made subversive achievements in various industries, and they are everywhere in industry, military, civilian and special industries. The combination of solar technology and robot technology has become inevitable for the future photovoltaic industry.

【detailed description】

The utility model will be described in further detail below in conjunction with the accompanying drawings, which is an explanation of the utility model rather than a limitation.

The utility model relates to a solar photovoltaic array surface cleaning robot, which is composed of a cleaning device and a control device, and the cleaning device cleans the solar panel 5 . The control device can set different cleaning times according to different regions and seasons to achieve the best cleaning effect and ensure the power generation efficiency of the solar photovoltaic array.

As shown in FIGS. 1 to 3 , the cleaning device is composed of a spring hose 1 , a self-cleaning film 2 , a one-way damping slide rail 6 , and a cleaning slide bar 4 . The spring hose 1 in the cleaning device is connected with a high-pressure air pump to provide power for the cleaning device. The self-cleaning film 2 in the cleaning device is arranged on the surface of the solar photovoltaic panel 5, and uses a nano-titanium dioxide film with good self-cleaning performance. One-way damping slide rail 6 adopts one-way hydraulic damping slide rail, which is used for shock resistance, allows movement at low speed, and locks when the speed or acceleration exceeds a corresponding value, forming a rigid support. The one-way damping slide rail 6 can quickly complete the movement in one direction due to the hydraulic transmission, and quickly reach the designated position without a sense of obstruction. When the hydraulic pump hydraulic oil falls back, the hydraulic oil produces a damping effect to avoid quickly returning to the initial position to damage the components. In the application of the photovoltaic panel cleaning robot, pneumatic power is used to generate power movement. In order to prevent the air nozzle 3 from rapidly falling back and cannot fully move to the designated position, one-way damping can produce a pause and slowly fall back. After the movement is completed, use gravity and the characteristics of the one-way damping slide rail to slowly fall back to the initial position.

The cleaning slide bar 4 is provided with a high-pressure air nozzle 3 and a cleaning brush 7, and the cleaning slide bar 4 is made of hollow stainless steel to reduce the corrosion of metal components by rain and snow. The cleaning sliding bar 4 is drilled to connect 4 to 6 high-pressure gas nozzles 3, the connection angle is 60 degrees with the solar photovoltaic panel 5, and the ventilation volume of the gas nozzles 3 can be adjusted. Therefore, the gas delivery rate, cleaning intensity, reaction force and upward movement speed of the cleaning rod can be adjusted according to the weather conditions and the like. The cleaning brush 7 is connected to the rear of the cleaning slide bar, and the cleaning brush adopts antistatic fiber to reduce the static electricity generated during the movement. The solar photovoltaic array surface cleaning robot is powered by a high-pressure air pump.

As shown in Figure 4, the control device uses a single timing switch to complete the integrated control of the total circuit. The access voltage of the solar photovoltaic cleaning robot is 220V, and the connection of the circuit uses the electric power of the photovoltaic power station. When the solar photovoltaic panel cleaning robot is connected, a transformer 9 needs to be connected to convert the 380V voltage into a 220V civilian voltage, which is convenient for access to the air pump 10 and timing Switch 11 supplies power. Wherein the solar photovoltaic panel battery 8 is connected to the transformer 9, and the high-pressure air pump 10 is controlled by the timing switch 11, and the high-pressure air pump 10 inflates the cleaning slide bar 4 through the spring hose 1.

As shown in Fig. 5, a single timing switch 10 completes the integrated control of the total circuit, and at the same time, the on-off time can be set according to the alternation of seasons, which reduces manpower and energy consumption.

A control method for a solar photovoltaic array surface cleaning robot, comprising the following steps:

Start the timing switch 11 first, control the high-pressure air pump 10 to inflate the cleaning slide bar 4 through the spring hose 1, and clean the surface of the solar photovoltaic panel 5 under the impact of the high-pressure gas in the air nozzle 3;

Simultaneously, the high-pressure air of air nozzle 3 produces reaction force and pushes cleaning slide bar 4 to move upward in one-way damping slide rail 6; The damping effect of the damping slide rail 6 continues to move upwards; when moving to the top of the solar photovoltaic panel 5, the cleaning of the photovoltaic panel is completed;

After the timing switch 11 is powered on, the air nozzle 3 stops spraying air, and the cleaning slider 4 slowly falls back under the joint action of gravity and the damping of the one-way damping slide rail. The brush 7 is used for the solar photovoltaic panel 5 twice clean.

Wherein, the setting time of the power-on of the timing switch 11 is equivalent to the time when the cleaning slide bar 4 moves to the top from the low end of the solar photovoltaic panel 5; The time for the top damping movement of the solar photovoltaic panel 5 to the low end is equivalent.

The specific working process of the utility model: start the timing switch 11, the high-pressure air pump 10 starts to work, inflate the cleaning slide bar 4 through the spring hose 1, and clean the surface of the photovoltaic panel 5 under the impact of the high-pressure gas ejected from the high-pressure air nozzle 3, and at the same time The air nozzle 3 has an included angle of 60 degrees with the surface of the photovoltaic panel, and moves upward in the one-way damping slide rail 6 under the reaction force of the high-pressure gas. Because the one-way damping slide rail has no upward resistance, the cleaning slide bar 4 can easily move upwards, and because there is a damping effect downward, the cleaning slide bar 4 will not fall quickly, and the damping action of the damping rod can support the continuous upward movement of the cleaning rod. After moving to the top of the photovoltaic panel 5 to complete the cleaning of the photovoltaic panel, after power-on, under the damping effect of the one-way damping slide rail, the cleaning slide bar 4 slowly falls back, and the brush 7 of the cleaning rod cleans the photovoltaic panel for the second time at the same time. surface.

In the robot control method of the utility model, the time control device sets different cleaning times according to different regions and seasons, which improves the power generation efficiency of the solar photovoltaic array and reduces the cost. Moreover, the control is accurate, manpower is saved for monitoring, and the cleaning work of solar photovoltaic panels is carried out independently. First, gas jet cleaning is performed, and then brush cleaning is performed. The cleaning work efficiency is greatly improved, and automatic control is realized.
