DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0025] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] like Figure 1-Figure 7 As shown, the present invention discloses a GNSS-based slope monitoring device, including a frame body, on which a GNSS receiver 1, a photovoltaic panel 5 and an electromechanical box 4 are arranged; a cleaning mechanism is slidably arranged on the photovoltaic panel 5, and the cleaning mechanism includes a power component, a transmission component and a dust cleaning component, the power component drives the transmission component to work under the action of wind, and the transmission component drives the dust cleaning component to move back and forth on the photovoltaic panel 5 in a straight line to remove dust on the photovoltaic panel 5. The photovoltaic panel 5 converts solar energy into electrical energy and stores it in a battery in the electromechanical box 4, and the battery provides electrical energy for various electrical components of the GNSS slope monitoring device.

[0027] It should be noted that the dust cleaning component can make linear reciprocating movements in the vertical direction or horizontal direction on the photovoltaic panel 5, and the specific setting is set according to the actual situation. The transmission component can be an existing mechanical structure that converts circular motion into linear reciprocating motion, such as a crank slider structure, etc., which will not be repeated here.

[0028] Specifically, the rack body includes a rack base 3 and a support column 2. The lower end of the support column 2 is fixedly arranged on the rack base 3, the GNSS receiver 1 is fixedly arranged on the top of the support column 2, and the electromechanical box 4 is fixedly arranged on the side wall of the support column 2. The rack base 3 is fixed to the ground by long bolts or long screws. One, two or more photovoltaic panels 5 can be arranged on the support column 2, and the specific number can be set according to needs. The preferred technical solution is as follows: Figure 1-2 As shown, two photovoltaic panels 5 are symmetrically arranged on the support column 2, and two support plates 6 are symmetrically arranged on the side wall of the support column 2. An adjustment rod 7 is fixedly arranged on the support plate 6, and the photovoltaic panel 5 is arranged by rotating the top of the adjustment rod 7 to adjust the angle.

[0029] Furthermore, the present invention also discloses a specific structure of a transmission assembly: the transmission assembly includes transmission chains 14 symmetrically arranged on both sides of the cleaning assembly along the moving direction of the cleaning assembly, and the two sets of transmission chains 14 are driven to rotate by the power assembly at the same time, and the two sets of transmission chains 14 have the same rotation direction; the transmission chains 14 are provided with retractable pushers, and the pushers push the cleaning assembly to move on the photovoltaic panel 5. During operation, the pushers are at the same position on the two sets of transmission chains 14. Since the two sets of transmission chains 14 are symmetrically arranged on both sides of the cleaning assembly, the two sets of transmission chains 14 have the same movement direction. When one of the pushers approaches the cleaning assembly and pushes the cleaning assembly to move, the other pusher just moves away from the cleaning assembly. When the pusher moves to the cleaning assembly and pushes the cleaning assembly to move, the pusher that was previously close to the cleaning assembly begins to move away from the cleaning assembly, thereby realizing the reciprocating linear motion of the cleaning assembly.

[0030] Further, the pusher includes a fixed block 21 fixedly arranged on the transmission chain 14, a limiting groove 22 is arranged on the side of the fixed block 21 away from the transmission chain 14, a limiting spring 23 is fixedly arranged in the limiting groove 22, and a stopper 20 adapted to the limiting groove 22 is arranged at one end of the limiting spring 23 away from the limiting groove 22; in the natural state, the limiting spring 23 is in the natural state, a part of the stopper 20 extends out of the limiting groove 22, and the other part is located in the limiting groove 22. When the pusher pushes the cleaning assembly, the limiting spring 23 is in the natural state. When the pusher pushes the cleaning assembly to the limit position (end point), the cleaning assembly cannot continue to move forward, and the cleaning assembly squeezes the stopper 20 into the limiting groove 22 until the stopper 20 is completely retracted into the limiting groove 22; after the stopper 20 passes through the cleaning assembly, the stopper 20 is partially pushed out of the limiting groove 22 under the action of the rebound force of the limiting spring 23.

[0031] Further, in order to allow the dust cleaning assembly to better squeeze the stopper 20, the end of the stopper 20 away from the limiting groove 22 is an arc-shaped portion. The end of the stopper 20 away from the limiting groove 22 can be a hemisphere or a minor arc sphere or a major arc sphere.

[0032] Furthermore, the cleaning assembly includes a cleaning rod 9 and a cleaning brush 8. The cleaning rod 9 is provided with a cleaning brush 8 on one side close to the photovoltaic panel 5. When cleaning, the cleaning brush 8 contacts the photovoltaic panel 5. The lower end of the cleaning rod 9 is provided with a sliding base 16. The sliding base 16 is provided with a sliding groove 15. The sliding groove 15 is adapted to the lower end of the cleaning rod 9. The lower end of the cleaning rod 9 is slidably arranged in the sliding groove 15. The sliding groove 15 limits the distance of the reciprocating linear motion of the cleaning assembly.

[0033] Furthermore, two groups of the transmission chains 14 are symmetrically arranged on both sides of the sliding base 16, and the sliding base 16 is provided with sliding through holes 19 on both sides close to the transmission chains 14. The two sliding through holes 19 and the sliding groove 15 form an inverted "T"-shaped slide groove, and the lower end of the dust cleaning component is adapted to the inverted "T"-shaped slide groove; the sliding through hole 19 is adapted to the stopper 20, and when the pusher pushes the dust cleaning component, the stopper 20 is slidably arranged in the sliding through hole 19. Specifically, two limit blocks 25 are symmetrically arranged at the lower end of the dust cleaning rod 9, and the two limit blocks 25 are adapted to the sliding through hole 19. In order to cooperate with the work of the transmission chain 14, the length of the sliding through hole 19 is greater than the length of the sliding groove 15, so that the pusher can enter or slide out of the sliding through hole 19.

[0034] Furthermore, the power assembly includes a wind plate 12 and a rotating rod 11 fixedly arranged at the lower end of the wind plate 12, and the wind plate 12 rotates in a circular motion along the axis direction of the rotating rod 11 under the action of wind force; a driving wheel 17 is fixedly arranged at one end of the rotating rod 11 away from the wind plate 12, and two driven wheels 13 are symmetrically meshed on the driving wheel 17, and the two driven wheels 13 respectively drive two sets of transmission chains 14 to rotate. It should be noted that the shape of the wind plate 12 can be square, circular or other shapes. The wind plate 12 rotates under the action of wind force, thereby driving the rotating rod 11 to rotate, the rotating rod 11 drives the driving wheel 17 to rotate, and the driving wheel 17 drives the two driven wheels 13 to rotate, thereby driving the transmission chain 14 to rotate.

[0035] In a further technical solution, the two driven wheels 13 are respectively fixedly connected to the driving wheel 17 of the transmission chain 14 through a transmission rod 18. The driving wheel 17 drives the two driven wheels 13 to rotate, and the driven wheel 13 drives the driving wheel 17 of the transmission chain 14 to rotate through the transmission rod 18, thereby driving the transmission chain 14 to rotate.

[0036] Furthermore, the dust cleaning mechanism also includes a protection box 10, which is detachably mounted on the lower end of the photovoltaic panel 5, and the sliding base 16, the driving wheel 17, and the driven wheel 13 are fixedly mounted inside the protection box 10. A sliding opening is provided on the top of the protection box 10 to allow the dust cleaning assembly to slide back and forth. One end of the rotating rod 11 extends out of the top of the protection box 10 and is connected to the wind board 12.

[0037] Furthermore, waterproof folding curtains (not shown) are symmetrically arranged at the lower end of the dust cleaning mechanism, and one end of the two waterproof folding curtains away from the dust cleaning mechanism is fixedly arranged at the end of the sliding opening, and the waterproof folding curtains are adapted to the sliding opening. The waterproof folding curtains can prevent dust from entering the protection box 10, thereby protecting the transmission component.

[0038] A working principle of a slope monitoring device based on GNSS: the wind plate 12 rotates under the action of wind force, thereby driving the rotating rod 11 to rotate, the rotating rod 11 drives the driving wheel 17 to rotate, the driving wheel 17 drives the two driven wheels 13 to rotate, thereby driving the transmission chain 14 to rotate; when the pushing member moves close to the cleaning component, the pushing member pushes the cleaning component to move on the sliding base 16, and the cleaning brush 8 cleans the dust on the photovoltaic panel 5; when the pushing member pushes the cleaning component to move to the extreme position (end point), the cleaning component cannot continue to move forward, and the cleaning component squeezes the block 20 into the limiting groove 22 until the block 20 is completely retracted into the limiting groove 22; after the block 20 passes through the cleaning component, the block 20 is partially pushed out of the limiting groove 22 under the action of the rebound force of the limiting spring 23; the pushing component on the other side begins to approach the cleaning component, driving the cleaning component to move in the direction, and the cleaning brush 8 continues to clean the dust on the photovoltaic panel 5. By symmetrically arranging two sets of transmission chains 14, no matter which direction the wind plate 12 rotates (not affected by the wind direction), the linear reciprocating motion of the dust cleaning component can be achieved.

[0039] The embodiments described above are only descriptions of the preferred modes of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
