Description

Technical Field

[0001] This utility model relates to the field of solar energy cleaning, and in particular to a combined photovoltaic panel spray cleaning device. Background Technology

[0002] Solar photovoltaic panels are a crucial component of solar power generation. Since they operate in open-air environments, they are highly susceptible to contamination from dust, droplets, and other pollutants, which can severely impact power generation efficiency and even damage the equipment. While equipment for cleaning solar photovoltaic panel surfaces has been developed to address this issue, it typically relies on high-pressure water or other liquid media to rinse the panels.

[0003] For example, Chinese utility model patent application number 201920732065.3 discloses a combined photovoltaic panel spray cleaning device. This solution can effectively meet the needs of cleaning operations on the surface of various solar photovoltaic panels with different structures. On the other hand, it can flexibly adjust the cleaning operation method on the surface of solar photovoltaic panels and can recover some of the pollutants generated during the cleaning operation, thereby effectively improving the flexibility and efficiency of the cleaning operation.

[0004] However, in the existing technology, there are also photovoltaic panels with curved shapes. The cleaning of such photovoltaic panels is carried out by workers using curved water spray pipes. Curved photovoltaic panels have a large installation area. Although the traditional curved water spray pipes can achieve the spraying and cleaning function, they need to be adjusted according to the length, width and curvature of the photovoltaic panel during installation. Customizing the corresponding water spray pipes on the market is not only more troublesome to operate, but also increases the maintenance cost of the aging water pipes, which is not ideal. Utility Model Content

[0009] Furthermore, a secondary component connecting flange is fixed to the end of the secondary spray connecting pipe. The secondary component connecting flange has several annularly distributed secondary component flange waist holes, and a first secondary component sealing ring is embedded at the inner ring edge of the secondary component connecting flange.

[0010] Furthermore, a sub-part mother flange is installed at one end of both the sub-nozzle and the shape memory alloy tube, and a sub-part daughter flange is installed at the other end of both the sub-nozzle and the shape memory alloy tube.

[0014] Furthermore, the auxiliary nozzle is provided in a set, and the auxiliary nozzle is connected together with the shape memory alloy tube.

[0015] The beneficial effects are as follows: by setting up a main spraying mechanism and a secondary spraying mechanism, there are multiple spraying methods, which can adapt to photovoltaic panels of different shapes, thus expanding the application range of the spraying device. Moreover, the device is relatively easy to install and maintain, without the need for traditional measurement of photovoltaic panel length or customization of matching spraying pipes, thus reducing the cost of use. Workers bent the shape of the shape memory alloy tube to change its bending shape, thereby adjusting the spray direction of the terminal auxiliary nozzle, so that the entire spraying device can be used for photovoltaic panels of different shapes.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0019] Example 1 The following is combined with Figures 1 to 8 The combined photovoltaic panel spray cleaning device provided in this embodiment will be further described as follows: Please refer to Figure 1-8 The present invention provides a combined photovoltaic panel spray cleaning device, including a main spray cleaning mechanism and a secondary spray cleaning mechanism. The main spray washing mechanism includes a main spray washing pipe 1, and a plurality of main water spray components 2 are provided on the main spray washing pipe 1 at equal intervals. In this embodiment, the plurality of main water spray components 2 are arranged in a linear pattern. The main spray cleaning pipe 1 has several auxiliary spray connecting pipes 5 on its pipe wall. In this embodiment, the several auxiliary spray connecting pipes 5 are distributed on two parallel lines, and the interval between two adjacent auxiliary spray connecting pipes 5 on each line is the same. The two lines are distributed on both sides of the main spray cleaning pipe 1. The main spray cleaning pipe 1 is arranged parallel to the outside of the photovoltaic panel. The main spray water component 2 sprays and cleans the surface of the photovoltaic panel. The auxiliary spray cleaning mechanism is installed on the auxiliary spray connecting pipes 5. The auxiliary spray cleaning mechanism includes a shape memory alloy tube 8 and at least one set of auxiliary spray pipes 7. The at least one set of auxiliary spray pipes 7 is provided with several auxiliary pipe spraying components 9. The shape memory alloy tube 8 is in the form of a corrugated pipe, which is bent by the elastic deformation of the metal and is fixed after the external force is removed. The several auxiliary pipe spraying components 9 on the auxiliary spray cleaning mechanism also clean the surface of the photovoltaic panel.

[0020] In this embodiment, the two ends of the main spray pipe 1 are respectively fixed with a main component female flange 3 and a main component sub-flange 4. Multiple main spray pipes 1 can be connected to each other by assembling the main component female flange 3 and the main component sub-flange 4 to form a longer spray washing device. The number of main spray pipes 1 can be increased or decreased according to the installation length or width of the photovoltaic panel. The main flange 3 has several main component waist holes 301 and positioning holes 303 on its annular surface. These holes are arranged in a ring on the annular surface of the main flange 3. A main component sealing ring 302 is embedded in the inner ring edge of the main flange 3. The main component sub-flange 4 has a main component waist hole 401 and a main component positioning rod 403 that match the main component waist holes 301 and positioning holes 303, respectively. The main component positioning rod 403 is inserted into the positioning hole 303 for positioning. The main component waist holes 301 and 401 are fixed by bolts. The inner ring edge of the main component sub-flange 4 has a main component annular groove 402, which allows part of the main component sealing ring 302 to snap into the main component annular groove 402 during the assembly of the main flange 3 and the main component sub-flange 4, achieving a sealing connection and preventing water leakage.

[0021] In this embodiment, the main spray washing mechanism also includes a main pipe seal 6, which is installed on the main component female flange 3 to achieve one-end sealing after the multiple main spray washing pipes 1 are assembled. The main sealing element 6 includes a main sealing plate 601, several main sealing element waist holes 602 and main sealing element positioning rods 604 provided on the main sealing plate 601. The number and size of the main sealing element waist holes 602 are the same as those of the main sealing element waist holes 301. The main sealing element positioning rods 604 are adapted to the positioning holes 303. The main sealing plate 601 and the main female flange 3 can be tightly connected by using bolts of the appropriate type. A main sealing element annular groove 603 is provided on one side of the main sealing plate 601. The main sealing element annular groove 603 is adapted to the main sealing ring 302.

[0022] In this embodiment, a secondary component connecting flange 501 is fixed at the end of the secondary spray connecting pipe 5. The secondary component connecting flange 501 is provided with a plurality of annularly distributed secondary component flange waist holes 502. A first secondary component sealing ring 503 is embedded at the inner ring edge of the secondary component connecting flange 501. The secondary component connecting flange 501 is used to connect and install the secondary spray washing mechanism.

[0023] In this embodiment, a sub-part mother flange 11 is installed at one end of the sub-nozzle 7 and the shape memory alloy tube 8, and a sub-part daughter flange 12 is installed at the other end of the sub-nozzle 7 and the shape memory alloy tube 8. The sub-part mother flange 11 and the sub-part daughter flange 12 facilitate the connection between the sub-nozzle 7 and the shape memory alloy tube 8. The sub-flange 12 is provided with several annularly distributed sub-flange waist holes 1201. The inner ring edge of the sub-flange 12 is provided with a sub-flange annular groove 1202. The sub-flange 11 is provided with a sub-flange waist hole 1101 that matches the sub-flange waist hole 1201. The inner ring edge of the sub-flange 11 is provided with a second sub-flange sealing ring 1102, which can effectively prevent liquid leakage and ensure the waterproof sealing of the connection.

[0024] In this embodiment, there are two sets of auxiliary nozzles 7, which are respectively installed at both ends of the shape memory alloy tube 8.

[0025] In this embodiment, the auxiliary spraying mechanism further includes an auxiliary pipe seal 10, which consists of an auxiliary sealing plate 1001 and a plurality of auxiliary sealing plate waist holes 1002 distributed annularly on the auxiliary sealing plate 1001. An auxiliary sealing plate annular groove 1003 is provided on one side of the auxiliary sealing plate 1001.

[0026] In this embodiment, the main water spray component 2 includes a main pressure nozzle 201 and a main threaded pipe 202. One end of the main pressure nozzle 201 is threaded to the main threaded pipe 202, which facilitates disassembly and maintenance, saves maintenance costs, reduces resource waste, and improves practicality. The outer side of the main pressure nozzle 201 is provided with main anti-slip texture 203. The secondary water spray component 9 has the same structure as the main water spray component 2.

[0027] In the above structure, during installation, bolts are used to fix the main component sub-flange 4 to the water inlet pipe, and then the remaining main spray pipes 1 are connected and fixed in sequence. The main pipe sealing element 6 is fixed on the main component female flange 3 at the top of the uppermost main spray pipe 1 for sealing. Then, bolts are used to install the two sets of auxiliary spray pipes 7 and shape memory alloy pipes 8 on both sides in sequence, and auxiliary pipe sealing element 10 is installed at the end of the outer auxiliary spray pipe 7 for sealing. Water can then be supplied for use. Before water supply, workers bend the shape memory alloy tube 8 to change its curvature, thereby changing the spray direction of the outer auxiliary nozzle 7. This allows the entire spraying device to perform spraying operations in the direction of the photovoltaic panel distribution or around the circumference of the curved photovoltaic panel. Utilizing the characteristics of the shape memory alloy tube, the spraying direction can be changed with just a simple bending operation, without the need to disassemble complex parts or replace equipment. This reduces the difficulty of on-site operation and time costs, making it easy to apply to large-area curved photovoltaic panels.

[0028] Example 2 The following is combined with Figure 9 The combined photovoltaic panel spray cleaning device provided in this embodiment will be further described as follows: Please refer to Figure 9 The present invention provides a combined photovoltaic panel spray cleaning device, including a main spray cleaning mechanism and a secondary spray cleaning mechanism. The difference from Embodiment 1 is that the secondary nozzle 7 is provided as a set, the secondary nozzle 7 is connected to the shape memory alloy tube 8, and the secondary nozzle 7 is located on the side away from the main spray tube 1.

[0029] In addition to the usage methods mentioned in Embodiments 1 and 2 above, the combined photovoltaic panel spray cleaning device can also be used with the auxiliary spray pipe 7 or the shape memory alloy pipe 8 removed, such as... Figure 10 In section a, the auxiliary nozzle 7 or the shape memory alloy tube 8 can be omitted. The auxiliary tube seal 10 is directly installed on the auxiliary connection flange 501, and only the main spray pipe 1 is used. Or such as Figure 10 As shown in b, the shape memory alloy tube 8 is removed, and only the auxiliary nozzle 7 is used. These two methods are used for cleaning planar photovoltaic panels.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
