The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done to describe in further detail.
As depicted in figs. 1 and 2, the utility model is used for the cleaning device on photovoltaic battery panel surface, comprise brush roll structure 5, and assembly pulley, described assembly pulley comprises three fixed pulleys that are arranged in order, as shown in Figure 3, fixed pulley in the middle of being positioned at is arranged on the output shaft of a motor 1, described motor 1 is by the fixed pulley 3 on steel wire rope 2 drive both sides, and described brush roll structure 5 comprises roller 51 and the felt 511 that is arranged on roller body 512 peripheries as shown in Figure 4 and Figure 5; The two ends of described roller 51 are provided with and are used for and the fixing steel wire rope fixture in steel wire rope 2 ends of walking around two fixed pulleys 3.Described steel wire rope fixture comprises the end cap that has projection 52, described projection 52 is embedded in one recessed 53 the groove, described recessed 53 form such as Fig. 8 and shown in Figure 9, described end cap is provided with a plurality of through holes, as Fig. 6 and shown in Figure 10, also be provided with the screwed hole consistent on two end faces of described roller 51 with these a plurality of lead to the hole site, adopt threaded connector to be connected between described end cap and the roller, described projection 52 matches with recessed 53, and steel wire rope 2 is embedded between projection 52 and recessed 53, and with fixedly steel cable screw 54 and dish-shaped nut 55 are fastening, as shown in Figure 4.
As Fig. 2 and shown in Figure 7, described steel wire rope is provided with miniature rigging 4 on the one section steel wire rope that is positioned at certain pulley outside, described miniature rigging 4 comprises the rope cap 41,43 that is arranged on a cylinder 42 two ends, the two ends of described cylinder 42 just are being respectively arranged with, the direction screwed hole, the outer end of two rope caps 41,42 is connected with two broken ends of steel wire rope 2, and the other end of described rope cap is connected with cylinder 42 by helicitic texture.
When installation the utility model is used for the cleaning device on photovoltaic battery panel surface, as depicted in figs. 1 and 2, motor 1 is fixed on the centre position, top of photovoltaic battery panel, two fixed pulleys 3 are fixed on the end positions of photovoltaic battery panel top, walk around fixed pulley the steel wire rope 2 that has miniature rigging 4 is installed, brush roll structure 5 is fixed on two of steel wire rope 2, and the position of adjusting the roller brush in the installation process is a basic horizontal.
The course of work of using the utility model cleaning device to remove the snow, remove water smoke (dew) is:
Because solar photovoltaic cell panel has the inclined-plane of 0 to 60 ° of angle towards the sun, the deadweight of brush roll structure 5 dependence itself has a downward sliding power, therefore, behind starter 1, the roller of brush roll structure 5 is to nestle up the purpose that the slip of photovoltaic battery panel surface reaches cleaning.Motor 11 rotates, middle fixed pulley 12 on the motor output shaft just rotates, and fix two steel wire ropes 2 on the pulley 12, see shown in Figure 3ly, when pulley 12 clockwise rotated, then both sides steel wire rope 2 was upwards packed up, when pulley 12 rotates counterclockwise, then both sides steel wire rope 2 relaxes, and the other end of both sides steel wire rope 2 is being fixed brush roll structure 5, and both sides steel wire rope 2 rises simultaneously or falls.The deadweight of brush roll structure 5 dependence itself has the trend of automatic downslide, and the soft wool felt 511 on the brush roll structure 5 has just been removed the dust on the photovoltaic battery panel, deposited snow, water smoke (dew).In addition, can also dispose manual and automatic control apparatus spare again, just reach the purpose of automatic cleaning with this.
On steel wire rope 2 on one side, dispose miniature rigging 4, when cleaning device is installed, if both sides steel wire rope 2 is during inconsistent height, perhaps because the climate relationship in winter or summer, when steel wire rope 2 might shrink or extend, two height of steel wire rope 2 will be inconsistent, and then available miniature rigging 4 positive left-hand threads are aligned both sides steel wire ropes 2, make the height unanimity on its both sides.
When soft wool felt 511 surface of brush roll structure 5 dirty, unrenewable, when perhaps cleaning effect is bad, then dish-shaped nut 55 can be unclamped, with roller 51 and the projection 52 that connects together rotational orientation together, make it to cooperate with recessed 53 that matches, then, tighten with dish-shaped nut, like this, just reached the purpose of felt surface commutation, comparatively clean roller brush surface is contacted with cell panel is surperficial, and outside dirty brush roll surface dashes, can be clean by natural rain drop erosion, need not artificial flushing, both economize the water source and saved labor management.
Although in conjunction with figure the utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; under the situation that does not break away from the utility model aim, can also make a lot of distortion, these all belong within the protection of the present utility model.
