Abstract

A cleaning mechanism having a water spray function adapted for cleaning photovoltaic panel is provided, which includes a cleaning rack, a cleaning member and a sweeping member. Cleaning rack includes several connecting rods detachably connected; Cleaning member is detachably mounted between the connecting rods and used for stripping off adhesive materials on photovoltaic panel; the sweeping member being detachably mounted on connecting rods and used for sweeping the adhesive materials away from the photovoltaic panel. A water spray device is detachably mounted on the cleaning rack used for wetting adhesive materials. The water spray device includes a water spray pipe and a water storage tank, and a spray nozzle atomizing water. A cleaning member power unit is detachably connected with the cleaning member and is used for driving the cleaning member to rotate; and the cleaning member power unit comprises a self-locking device used for preventing cleaning member from idling.

Claims

1. A cleaning mechanism having a water spray function, adapted for use on a photovoltaic panel together with a body of a photovoltaic panel cleaning equipment having a central controller, comprising:

a cleaning rack, the cleaning rack comprising a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod which are detachably connected;

a cleaning member, the cleaning member being detachably mounted between the first connecting rod and the third connecting rod and used for stripping off adhesive materials on the photovoltaic panel;

a sweeping member, the sweeping member being detachably mounted on the second connecting rod and the fourth connecting rod of the cleaning rack, and used for sweeping adhesive materials away from the photovoltaic panel;

a water spray device, comprising;

a water spray pipe and a water storage tank, wherein the water spray pipe is communicated with the water storage tank, the water spray pipe is detachably mounted on the sweeping member, a water pressure pump is mounted in the water storage tank, and the water pressure pump is connected with the water spray pipe and is used for pumping water in the water storage tank into the water spray pipe;

a water amount detection and alarm device arranged in the water storage tank and used for detecting an amount of water in the water storage tank and giving out alarm information when water is in shortage;

a path recording unit, wherein when the water amount detection and alarm device detects that the water storage tank is in shortage of water, the path recording unit then records distance data of movement of the body from a water shortage point to a water getting point, and after water is obtained, the central controller of the body of the photovoltaic panel cleaning equipment controls the body thereof to move to the position of the original water shortage point according to the distance data and controls the cleaning mechanism having the water spray function to continuously perform remaining cleaning work until completion; and

a water suction device, wherein the water suction device is used for sucking water at the water getting point into the water storage tank; and

a cleaning member power unit,

wherein the water spray device is detachably mounted on the cleaning rack and is used for wetting adhesive materials on the photovoltaic panel;

the cleaning member power unit is detachably connected with the cleaning member and is used for driving the cleaning member to rotate; and

the cleaning member power unit comprises a self-locking device, and the self-locking device is used for preventing the cleaning member from idling.

2. The cleaning mechanism having a water spray function according to claim 1, wherein a spray nozzle that atomizing water is mounted on the water spray pipe.

3. The cleaning mechanism having a water spray function according to claim 1, wherein the cleaning member power unit further comprises a rolling brush motor, and the self-locking device is located between the rolling brush motor and the cleaning member;

and when the rolling brush motor stops, the self-locking device enables the cleaning member to instantaneously stop rotating.

4. A photovoltaic panel cleaning equipment, adapted for use on a photovoltaic panel, comprising:

a body, the body comprises the cleaning mechanism having a water spray function comprising;

a cleaning rack, the cleaning rack comprising a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod which are detachably connected;

a cleaning member, the cleaning member being detachably mounted between the first connecting rod and the third connecting rod and used for stripping off adhesive materials on the photovoltaic panel;
