Abstract

The present invention is a glass surface cleaning device including an elongated swing arm and an elongated cleaning brush pivotally connected to the swing arm. The swing arm, by using its one end as the fulcrum, drives the cleaning brush to perform reciprocal swing. When the cleaning brush swings toward one side in accordance with the swing arm, one stopping member limits the cleaning brush, and when the swing arm continuously swings toward the same side, the cleaning brush generates the pivot rotation. Moreover, an elasticity restoration unit is disposed in between the swing arm and the cleaning brush to store the elastic force potential energy when the cleaning brush is pivotally rotated, and the elastic force potential energy is released when the swing arm backwardly swings such that the cleaning brush is restored to achieve the purpose of reciprocation and large-area glass surface cleaning.

Further, the elastic recovery unit includes two elastic pieces disposed on two sides of the swing arm, and a first roller disposed on the cleaning brush, the first roller extending between the two elastic pieces and abutting against the two elastic pieces.

Further, the elastic recovery unit includes a torsion spring sleeve disposed on the shaft, a positioning block is fixed on the swing arm, and an operation block is fixed on the cleaning brush, and the torsion spring extends with two compression ends, and the torsion spring extends The positioning block extends with two positioning ends abutting against the two compression ends of the torsion spring, and the operation block extends with two operating ends against the two compression ends of the torsion spring.

Further, the stopping member is a sliding rail, and a second roller is disposed on the cleaning brush to correspond to the sliding rail.

The invention has the following effects:

1. Use the swing arm to drive the cleaning brush to swing, and use the cleaning brush to pivot on the swing arm, so that the swing arm can clean a large area of glass at a small swing angle.

2. The invention is suitable for cleaning solar photovoltaic panels, lighting hoods or glass curtains to maintain the penetration of sunlight.

In summary of the above technical features, the main effects of the glass surface cleaning apparatus of the present invention can be clearly demonstrated in the following examples.

Referring to the first figure, the first embodiment of the present invention includes:

The roller (23) corresponds to the slide rail (4) such that the cleaning brush (2) is constrained on the slide rail (4) and pivots around the shaft (3) by the second roller (23) Rolling in the slide rail (4) without causing scratches or other injuries to the cleaning brush (2) [please refer to the fourth and fifth figures]; an elastic recovery unit (5), setting In the swing arm (1) and the cleaning brush (2) The elastic position energy is stored when the cleaning brush (2) pivots around the shaft (3), and the elastic position energy is released when the swing arm (1) swings back, so that the cleaning brush (2) is reset [Please Referring to the fourth and fifth figures, in the embodiment, the elastic recovery unit (5) includes two elastic pieces (51) disposed on two sides of the swing arm (1), and a first roller (52) Provided on the cleaning brush (2), the first roller (52) extends between the two elastic pieces (51) and abuts against the two elastic pieces (51), and therefore, except by the first roller (52) Supported between the two elastic pieces (51) such that the cleaning brush (2) can be stably swung with the swing arm (1), and when the cleaning brush (2) pivots around the shaft (3), The cleaning of the cleaning roller (2) can be made smooth by the rotation of the first roller (52) and the rolling of the second roller (23).

Referring again to the second to fifth figures, one end of the swing arm (1) is connected to a power unit (A), and the cleaning surface of the cleaning brush (2) is abutted against a glass (B). And simultaneously fixing the slide rail (4) to the appropriate position on the glass (B), for example, in the figure, the swing arm (1) and the cleaning brush (2) are located in the center of the glass (B), and The slide rail (4) is fixed to the appropriate height on both sides of the glass (B), and the power unit (A) is activated to cause the swing arm (1) to swing the cleaning brush (2) to clean the surface of the glass (B). Before the cleaning brush (2) is not restricted by the sliding rail (4), the surface of the glass (B) is cleaned in a fan shape, and when the cleaning brush (2) is limited by the sliding rail (4), the The pivoting of the cleaning brush (2) allows the second section (22) of the cleaning brush (2) to be brushed to the glass (B) below the sector, thereby enabling cleaning of large areas of glass at a small angle of oscillation (B) Surface.

Referring to the fifth figure, the cleaning brush (2) is pivoted in different directions according to the swinging direction of the swing arm (1), and the first roller (52) compresses the two elastic pieces (51). 1. When the swing arm (1) swings back, the two elastic pieces (51) release the elastic force to push against the first roller (52) to reset the cleaning brush (2), thereby reciprocating Clean the surface of the glass (B).

The second embodiment of the present invention is shown in the sixth figure, and is different from the first embodiment in that:

The elastic recovery unit (5A) includes a torsion spring (51A) sleeved on the shaft (3), a positioning block (52A) is fixed to the swing arm (1), and an operating block (53A) is fixed to the On the cleaning brush (2), the torsion spring (51A) extends with two compression ends (511A), and the positioning block (52A) extends with two positioning ends (521A) against the compression of the torsion spring (51A). The end (511A), the operating block (53A) extends with two operating ends (531A) against the two compression ends (511A) of the torsion spring (51A).

Referring to FIG. 7 and FIG. 8 again, the torsion spring (51A) is abutted against the two compression ends (511A) of the torsion spring (51A) by the positioning end (521A) of the positioning block (52A). Positioning, when the cleaning brush (2) is pivoted by the sliding rail (4), the compression end (511A) of the torsion spring (51A) is pushed by the operating end (531A) of the operating block (53A), The torsion spring (51A) stores the elastic potential energy. When the swing arm (1) swings back, the torsion spring (51A) releases the elastic potential energy, and the operating end (53A) is moved by the compression end (511A). The cleaning end ( 531A) is used to reset the cleaning brush ( 2 ).

Since the solar photovoltaic panel, the glazing cover or the glass curtain is exposed to the outdoor environment for a long time, it is easy to block the penetration of sunlight due to dust or dirt, affecting the light collecting efficiency, and the invention can be cleaned at the right time to maintain the high penetration of sunlight.
