The right slide bar and the elbow of the right rod part are connected together in a sealing way through a right flexible water-receiving cloth 46. The lower side of the right flexible water receiving cloth 44 is provided with a right flexible water retaining edge 461. The right flexible water receiving cloth is positioned above the right sliding rod. A water receiving groove 4 which is obliquely arranged and used for collecting rainwater is formed among the left water retaining strip, the left flexible water receiving cloth, the light source, the right flexible water receiving cloth and the right water retaining strip. The light source is provided with a double-headed motor 47. A power output head of the double-head motor is provided with a left thread head 48, the other power output head is provided with a right thread head 49, the left thread head is in threaded connection with the left water bar, the right thread head is in threaded connection with the right water bar, and the thread directions of the left thread head and the right thread head are opposite. And water inlet channels 17 communicated with the water receiving tank and the water tank are arranged in the left side rod and the right side rod. Under the blocking effect of the right flexible water blocking edge, the left flexible water blocking edge and the light source part water bar, water flowing downwards from the water receiving tank converges to the two water outlet notches 162 on the light source part water bar 161, so that the water enters the water inlet channel and finally flows into the water tank.
When raining, the double-end motor drives the left and right screw heads to rotate, so that the right water retaining strip and the left water retaining strip are separated to enable the area of the water receiving tank to be larger, rainwater falling into the water receiving tank is collected together, then water flowing downwards from the water receiving tank converges to the two water outlet notches 162 on the light source part water retaining strip 161, and therefore the rainwater enters the water inlet channel and finally flows into the water tank. When the solar panel needs to be cleaned, the nozzle is opened, so that water in the water tank is sprayed to the front surface (the front surface is the light receiving side of the solar panel) of the solar panel 3 for cleaning. In non-rainy days, the double-end motor drives the left and right screw heads to rotate so as to enable the right water retaining strip and the left water retaining strip to be folded, so that the area of the water receiving tank is smaller, and damage caused by wind is avoided.
The third embodiment is different from the second embodiment in that:
referring to fig. 4, 5 and 6, a brush fixing rod 5 extending in the left and right direction is further included. The brush fixing rod is provided with a row of brush hairs 51 which are distributed along the extending direction of the brush fixing rod and are abutted against the front surface of the solar panel. The left and right ends of the solar panel are provided with sliding grooves 31 extending in the up-down direction. A slider 32 is slidably connected in the chute. The sliding block is connected with the brush fixing rod. A flexible inflation mandril 52 with the upper end connected with the slide block and a flexible inflation pressure bar 53 with the lower end connected with the slide block are arranged in the ring groove. An inflation three-way valve 54 is fixed on the lower end of the solar panel. The three-way valve is an electric valve. The lower end of the winding inflation ejector rod is connected with a first air outlet 541 of the inflation three-way valve. The upper end of the wire-wound inflation pressure lever is connected with the second air outlet 542 of the inflation three-way valve. The spout is equipped with notch section 33 and expansion spacing section 34 along spout depth direction from the notch to the tank bottom in proper order. The flexible inflation ejector rod and the flexible inflation pressure rod are arranged in the expansion limiting section in a penetrating mode. The outer diameter of the flexible inflating mandril is more than 2 times of the opening width of the notch section. The outer diameter of the flexible inflation pressure lever is more than 2 times of the opening width of the notch section. The brush fixing rod is provided with an upper air chamber 55 and a lower air chamber 56 extending in the extending direction of the brush fixing rod. The upper air chamber is provided with an upper air outlet gap 551 which extends along the extension direction of the brush fixing rod and is positioned above the brush hair. The upper air chamber is communicated with the flexible inflation pressure rod through a flexible inflation pressure rod deflation electric valve 552. The lower air chamber is provided with a lower air outlet gap 561 which extends along the extension direction of the brush fixing rod and is positioned below the brush hair. The lower air chamber is communicated with the flexible inflating mandril through the flexible inflating mandril deflating electric valve 562.
In this embodiment, a control unit, a brush fixing lever ascending stroke end point detection switch 521 and a brush fixing lever descending stroke end point detection switch 531 are further provided. The nozzle 21 is a push button type nozzle. The brush fixing lever is provided with a pressing block 57 for pressing a button of the push button type nozzle when the brush is lifted to a set position.
At the initial state, neither the flexible inflating push rod 52 nor the flexible inflating pressure rod 53 is inflated, and at this time, the brush fixing rod is at the lowest position (i.e., the descending stroke end point) under the action of the self weight of the brush fixing rod. When the solar panel needs to be cleaned, the air inlet 543 of the air inflation three-way valve is connected with the outlet end of the air pump. The control unit is driven, the brush fixing rod descending stroke end point detection switch detects that the brush fixing rod descends to a descending end point position, the electric appliance is controlled to enable the flexible inflation ejector rod deflation electric valve to be closed, the flexible inflation pressure rod deflation electric valve to be opened and the air outlet hole of the three-way valve to be communicated with the first air outlet of the inflation three-way valve, and therefore the flexible inflation pressure rod deflation air flows out through the upper air outlet gap 551, the solar panel is blown to be cleaned, meanwhile, the flexible inflation ejector rod is inflated to enable the brush fixing rod to ascend. When the brush fixing rod rises to the highest position, namely the ascending stroke end point, the ascending stroke end point detection switch detects that the brush fixing rod rises to the ascending end point position, the control electric appliance enables the flexible inflating ejector rod deflation electric valve to be opened, the flexible inflating press rod deflation electric valve to be closed and the air outlet hole of the three-way valve to be communicated with the second air outlet of the inflating three-way valve, so that the air pump inflates the flexible inflating press rod, the flexible inflating ejector rod deflates to enable the brush fixing rod to descend, and the air discharged by the flexible inflating ejector rod flows out through the lower air outlet gap 561 to blow the solar. And the process is repeated so that the brush cleans and blows air to clean the front surface of the solar panel. When the brush fixing rod rises to a set height, the button pressed to the nozzle by the pressing block enables the nozzle to be opened to spray water to the surface of the solar panel for cleaning. When the pressing block releases the press of the button, the nozzle stops spraying water. Thereby avoiding the phenomenon of large good water quantity caused by the over-time water spraying.
