Description

Technical Field

[0001] The utility model relates to a cleaning water spraying frame mechanism suitable for a photovoltaic panel cleaning vehicle, in particular to a cleaning water spraying frame mechanism for a photovoltaic panel cleaning vehicle. Background Technique

[0002] For a photovoltaic panel cleaning vehicle, whether the cleaning water spraying frame mechanism is reasonably designed plays a key role in the cleanliness of the vehicle for cleaning photovoltaic panels and water conservation.

[0003] At present, most of the existing cleaning water spraying frames of photovoltaic panel cleaning vehicles are double spray rods. When cleaning, the water flow sprayed by the high-pressure nozzles is perpendicular to the mirror surface of the photovoltaic panel, resulting in poor cleaning effect. Moreover, when the double spray rods spray water simultaneously, it is impossible to switch to the single spray rod cleaning mode only. When cleaning photovoltaic panels with relatively less dust, it is too wasteful of water resources and also increases the cleaning cost. Summary of the Invention

[0004] The utility model aims to solve the above deficiencies and provides a cleaning water spraying frame structure suitable for a photovoltaic panel cleaning vehicle. It consists of two parallel spray rods, which are fixedly connected by a cross bar. Nozzles are evenly installed on both spray rods. The nozzles on one spray rod are perpendicular to the horizontal plane, and the nozzles on the other spray rod form an angle of 50° - 65° with the horizontal plane; an inlet joint is arranged on one spray rod, the inlet joint is connected to a connecting pipe, the other end of the connecting pipe is connected to a ball valve, and the ball valve is connected to the other spray rod; a cylinder bracket is fixedly installed on the cross bar close to the connecting pipe, a cylinder is installed on the cylinder bracket, and the piston end of the cylinder is movably connected to the ball valve handle of the ball valve.

[0005] In order to detect the distance between the water spraying frame and the photovoltaic panel in real time, mounting plates are fixedly installed on both cross bars far from the connecting pipe, and ultrasonic ranging sensors are fixedly installed on the mounting plates.

[0006] In order to facilitate the cleaning of the spray rods, plugs are installed at both ends of both spray rods.

[0007] In order to better wash the photovoltaic panel, the nozzles are high-pressure nozzles.

[0008] In order to facilitate the assembly of the ball valve, the connecting pipe is a flexible pipe.

[0009] The utility model has the following beneficial effects:

[0010] 1. Solved the problem that when the double spray rods of the photovoltaic panel cleaning vehicle are cleaning, the water flow sprayed by the high-pressure nozzles is perpendicular to the mirror surface of the photovoltaic panel, it is not easy to wash the dust forward to avoid the already cleaned mirror surface of the photovoltaic panel, and it is impossible to switch to the single spray rod cleaning mode only.

[0011] 2. According to the dust accumulation degree of the photovoltaic panel, a single-rod cleaning operation mode with an included angle of 50°-65° between the nozzle and the horizontal plane can be adopted, or a double-rod water spraying cleaning operation mode can be adopted. For photovoltaic panels with more dust, the double-rod water spraying cleaning operation mode is adopted, and for photovoltaic panels with less dust, a single-rod water spraying cleaning operation mode with an included angle of 50°-65° between the nozzle and the horizontal plane is adopted, which saves water and reduces costs.

[0012] 3. The single-rod water spraying cleaning operation mode and the double-rod water spraying cleaning operation mode can be switched at any time and place, with a high degree of automation. Description of the Drawings

[0019] As Figure 1 and Figure 2 shown, a cleaning water spraying frame structure applicable to a photovoltaic panel cleaning vehicle, which comprises two spray bars 1 arranged in parallel. The two spray bars 1 are fixedly connected by a cross bar 2. Nozzles 9 are evenly installed on both spray bars 1. It is characterized in that: the nozzles 9 on one spray bar 1 are perpendicular to the horizontal plane, and the nozzles 9 on the other spray bar 1 form an angle of 50° - 65° with the horizontal plane; an inlet joint 4 is arranged on one spray bar 1. The inlet joint 4 is communicated with a connecting pipe 10. The other end of the connecting pipe 10 is connected to a ball valve 11. The ball valve 11 is connected to the other spray bar 1; a cylinder bracket 3 is fixedly installed on the cross bar 2 close to the connecting pipe 10. A cylinder 13 is installed on the cylinder bracket 3. The piston end of the cylinder 13 is movably connected to the ball valve handle 12 of the ball valve 11.

[0020] The nozzles 9 are distributed on the two spray bars 1. The nozzles 9 on one are distributed at 90° to the horizontal plane, and the nozzles 9 on the other are distributed at 50° - 65° to the horizontal plane. The water flow sprayed by the nozzles 9 is in a fan shape. The inlet joint 4 is connected to the outlet pipe of the high-pressure water system to provide high-pressure water source for the cleaning water spraying frame mechanism. The cleaning water spraying frame mechanism only keeps the two spray bars 1 communicated at the connection where the ball valve 11 and the connecting pipe 10 are installed. The large head end of the ball valve handle 12 is installed on the rotating shaft of the ball valve 11 switch, and the small head end is hingedly connected to the piston rod head of the cylinder 13. The tail of the cylinder barrel of the cylinder 13 is hingedly installed on the cylinder bracket 3.

[0021] Furthermore, mounting plates 6 are fixedly installed on both cross bars 2 far from the connecting pipe 10. Ultrasonic distance sensors 8 are fixedly installed on the mounting plates 6.

[0022] Two ultrasonic distance measurement sensors 8 are respectively installed on the two ultrasonic distance measurement sensor mounting plates 6. The signal output end of the ultrasonic distance measurement sensor 8 is connected to the electrical system. When cleaning the photovoltaic panel, the ultrasonic distance measurement sensor 8 will measure the distance between the cleaning water spraying frame and the mirror surface of the photovoltaic panel in real time, transmit signals to the electronic control system, and the electrical system and the hydraulic system will control the robotic arm to automatically adjust the distance between the cleaning water spraying frame mechanism and the mirror surface of the photovoltaic panel to always maintain a set distance, and will not change due to the slight deviation generated when the vehicle is moving, so as to realize the automatic avoidance of the cleaning water spraying frame mechanism for the mirror surface of the photovoltaic panel.

[0023] Further, plug heads 7 are installed at both ends of the two spray bars 1.

[0024] Two plug heads 7 are respectively installed at the ends of the two spray bars 1. The function of the plug head 7 is detachable. After being removed, the sediment in the spray bar 1 can be flushed.

[0025] Further, the nozzle 9 is a high-pressure nozzle.

[0026] Further, the connecting pipe 10 is a high-pressure hose.

[0027] The connecting pipe 10 is a hose, which avoids the problems that the rigid connection of the ball valve 11 is not easy to assemble and is easy to pull off.

[0028] The water outlet end of the ball valve 11 is installed on the spray bar 1 that is at a 90° angle to the horizontal plane near the nozzle 9 and is connected to it. The water inlet end of the ball valve 11 is connected to one end of the high-pressure water hose 11, and the other end of the high-pressure water hose 11 is connected to the spray bar 1 that is at an angle of 50° - 65° to the horizontal plane with the nozzle 9. The air cylinder 13 controls the opening and closing of the ball valve 11. When the piston rod of the air cylinder 13 is in the original retracted state, the ball valve 11 is in the open state, and the two spray bars 1 are both connected to the high-pressure water circuit. At this time, the cleaning water spraying frame mechanism is in the double-spray-bar water spraying mode; when the piston rod of the air cylinder 13 extends to drive the ball valve rocker 12 to rotate 90° around the rotation axis of the ball valve 11 switch, the ball valve 11 is in the closed state. At this time, only the spray bar 1 that is at an angle of 50° - 65° to the horizontal plane with the nozzle 9 is connected to the high-pressure water circuit. At this time, the cleaning water spraying frame mechanism is in the single-spray-bar water spraying mode.

[0029] The above is only the embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention.
