technical field

The invention relates to the technical field of solar energy utilization, in particular to a movable solar component cleaning device.

Background technique

Under the background of increasingly tense supply of fossil energy, all countries in the world are striving to seek a stable and sufficient energy supply, among which large-scale development and utilization of renewable energy has become an important part of the energy strategy of various countries in the future. Solar energy is an inexhaustible renewable energy for human beings. It has sufficient cleanliness, absolute safety, relative extensiveness, long life and maintenance-free, resource adequacy and potential economy. It has an important position in the long-term energy strategy. The application space of my country's solar power generation industry is also very broad. It can be applied to grid-connected power generation, combined with building materials, and solving the problem of difficult electricity consumption in remote areas.

Solar photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert sunlight into electrical energy. The solar power generation system mainly includes: solar cell components, controllers, batteries, inverters, loads, etc. The solar battery module is the core part of the power generation system. Its function is to directly convert the sun's radiant energy into direct current, which is used by the load or stored in the battery for backup. Generally, according to the needs of users, a number of solar panels are connected in a certain way to form a solar cell array (array), and then equipped with appropriate brackets and junction boxes to form a solar cell module.

The solar cell modules exposed outdoors are very easy to accumulate dust, which not only affects the lighting effect and reduces the conversion efficiency, but also affects the conversion efficiency when the temperature of the solar cell modules is too high in summer. Therefore, the solar cell components must be cleaned and cooled in time.

The cleaning of solar panel components in traditional photovoltaic power stations mainly relies on manual scrubbing or the use of simple scrubbing tools. The cleaning process of these methods is relatively cumbersome and inefficient.

In order to solve the above problems, some solutions have been proposed in the prior art, such as a utility model patent with a publication date of July 25, 2012 and a publication number of CN202667184U, which discloses "a solar module cleaning and cooling system for photovoltaic grid-connected power stations", The system includes: a controller, which is respectively connected with the temperature sensor and the dust level monitor installed on the solar module, so as to obtain the temperature of the solar module and the dust level information of the environment where the controller is located. The device is connected so as to activate and close the spraying device according to the obtained information, and the spraying head is installed on the spraying device so as to spray water to clean the solar module. The cleaning and cooling system uses automatic equipment to realize the cleaning of solar cell components in photovoltaic power plants, which changes the current situation and problems of long duration, low efficiency, and high cost mainly caused by manual wiping, effectively reduces the operation and maintenance costs of photovoltaic power plants, and It is beneficial to improve and ensure the system efficiency and investment benefit of the photovoltaic power station.

However, the above-mentioned cleaning and cooling system requires the construction of a water pump room. In severe cold areas, the water pipes are prone to freezing and cracking if the insulation protection is not good, resulting in the failure of normal use of the equipment, and adding thermal protection equipment will increase the cost of cleaning and cooling system; and the nozzles are fixed nozzles. , the number of nozzles required is large, which also increases the cost, and the spraying areas of different nozzles overlap each other, which reduces the efficiency of spraying and is not suitable for spraying large-area solar cell modules; in addition, the nozzles are relatively solar modules. A reasonable spray angle will not adjust the spray angle with the adjustment of the elevation angle of the solar panel, and the efficiency cannot be maximized.

If there are two sets, the transmission mechanism 2. There are also two sets of angle adjustment mechanisms 5 and housings 4; meanwhile, two rotating bases 12 are required, one is set on the left front side and the other is set on the right front side. The swivel base 12 can also be installed on the right rear side or the left rear side of the mobile vehicle.

Wherein, the free end of the cylinder 13 is hinged on the lower surface of the rotating base 12 , and the upper surface of the rotating base 12 is used to connect the supporting arm 21 and the telescopic arm 22 in the transmission mechanism 2 .

Driven by the cylinder 13, the rotating base 12 can rotate around its rotation center, and the rotation angle is 0-135 degrees, but the rotation angle in the working state can be 45-135 degrees but not vertical, that is, 45-89, 91 -135 degrees, preferably 100 degrees, the reason for which will be introduced later when the spray washing mechanism 3 is introduced. The purpose of the rotation of the rotating base 12 is to switch between the vehicle body parallel to the mobile vehicle 11 and perpendicular to the vehicle body of the mobile vehicle 11 under the drive of the transmission mechanism 2 when the spray washing mechanism 3 is switched between the working state and the non-working state. .

The longitudinal centerline of the support arm 21 is always parallel to the longitudinal centerline of the telescopic arm 22 .

3. Angle adjustment mechanism

The effect of the angle adjustment mechanism 5 is to adjust the angle between the spray rod 33 of the spray washing mechanism 3 and the horizontal plane. In order to adapt to seasonal changes, the angle between the solar panel and the horizontal plane needs to be adjusted, for example, between 16, 36, and 56 degrees. The spray rod 33 needs to be always parallel to the solar panel, so the angle between the spray rod 33 and the horizontal plane also needs to change accordingly.

The rear end of the connecting rod 52 is fixed on both ends of the upper beam 56 and is also fixedly connected to the angle adjusting plate 53 . The front end of the connecting rod 52 may have multiple hinges at different positions to connect the counterweight, so as to correspond to multiple different elevation angles of the solar panel due to seasonal changes.

The angle adjusting plate 53 is pivotally connected to the lower beam 58 through the bushing, and the lower beam 58 is fixedly connected between the two lower extensions 230 extending downward of the cross arm 23 . Both ends of the upper beam 56 are hinged between the top ends of the two angle adjusting plates 53 . The middle part of each angle adjustment plate 53 has an oblong hole 55, and two oblong holes 55 are pierced with adjustment bolts 54. The different positions of the adjustment bolts 54 in the oblong holes 55 correspond to the adjustment between the spray bar 33 and the horizontal plane in different seasons. varying elevation angles. A connecting beam 57 is fixed at the midpoint of the adjusting bolt 54, and the connecting beam 57 is fixed on the upper surface of a four-way pipe. The front and rear direction of the four-way pipe is for the spray rod 33 to pass through, and the left and right direction is for the connection of the lower beam 58. This connection essentially enables the spray rod 33 to rotate around the lower beam 58, and is on the angle adjustment plate 53 rotates around the lower crossbeam 58 when rotating, and the power of the angle adjustment plate 53 rotation comes from the drive of the cylinder 51 and the gravity effect of the counterweight 59.

Wherein, one end of the cylinder 51 and the angle adjustment plate 53 is hinged through the hinge E, and the connecting rod 52 is fixedly connected to the hinge E, and the fixed end of the cylinder 51 is fixedly connected to the point F on the cross arm 23, and the bottom of the angle adjustment plate 53 The end and the lower extension part 230 are connected to point O through the rotating shaft (that is, the lower beam 58). Due to the role of the counterweight 59, no matter what the relative position of the spray bar 33 and the solar panel is, the angle formed by the spray bar 33 and the horizontal plane remains unchanged. When the cleaning is completed and the cleaning equipment is put away , the cylinder 51 is elongated, the connecting rod 52, the counterweight 59 and the beam 58 below the hinge point E of the angle adjustment plate 53 (that is, the position of the connection point O) rotate in the direction of the elongation of the cylinder 51, and then drive the front end of the spray rod 33 Close to the direction of the cross arm 23, otherwise when cleaning is required, the cylinder 51 shrinks so that the front end of the spray rod 33 is away from the cross arm 23, and the spray rod 33 is moved closer to the direction of the solar cell assembly; the dotted arrow in Fig. 5 Shown is the movement direction of point E when the cylinder 51 is extended, and the solid line arrow shows the rotation direction of the spray rod 33 .
