Description

Technical Field

[0001] The utility model relates to the field of liquid filling devices, in particular to an acid- and alkali-resistant, metal-contact-free automatic filling device for photovoltaic liquid additives. Background Art

[0002] Photovoltaic liquids generally refer to various liquid materials used in the manufacturing process of photovoltaic cells or photovoltaic modules. These materials play an important role in improving the performance of photovoltaic devices and extending their service life. In order to improve the conversion efficiency and service life of photovoltaic panels, it is usually necessary to add some specific liquid additives during the production process. These additives may be corrosive or chemically active. Traditional filling equipment contains metal parts and may react with these liquids, causing equipment damage or contamination of the additives, affecting the quality of the final product.

[0003] In the existing photovoltaic liquid additive filling technology, a series of problems often arise due to improper equipment structure and material selection. When ionic liquid additives come into contact with metal parts, metal ions may dissolve into the liquid, or corresponding metal halides may be produced after contact with specific metals. These chemical reactions will directly affect the purity of the additive components. In addition, even if the metal pipes and barrels are coated with corrosion-resistant coatings, they are prone to excessive corrosion if used for a long time and not maintained in time. This will not only affect production efficiency, but also increase equipment maintenance and replacement costs. Therefore, it is necessary to design an acid- and alkali-resistant, metal-free automatic filling device for photovoltaic liquid additives to address the shortcomings of the existing technology.

When the motor drives the turntable to rotate, the turntable will alternately drive the first connecting rod and the second connecting rod to perform a lifting and reciprocating motion. The piston block on the second connecting rod performs a piston motion in the filling barrel, and cooperates with the one-way action of the one-way valve one and the one-way valve two to enable the additive in the storage barrel to be alternately drawn into the filling barrel, and then the additive is discharged from the liquid outlet pipe of the filling barrel.

When the piston block in the filling cylinder rises, the one-way valve 2 cannot be conducted and the one-way valve 1 is conducted, so that the additive in the storage cylinder is injected into the filling cylinder. When the piston block in the filling cylinder descends, the one-way valve 2 is conducted and the one-way valve 1 cannot be conducted, so that the additive in the filling cylinder is discharged from the liquid outlet pipe for automatic filling.

[0007] Optionally, the turntable is further provided with an adjusting member, which includes a slider, a locking ball and a spring. The turntable is provided with a sliding groove, and a slider is slidably installed in the sliding groove of the turntable.

By sliding the adjustment slider in the sliding groove of the turntable, the locking ball is locked into the locking hole of the slider under the action of the spring, so that the stroke of the first connecting rod and the second connecting rod driven by the turntable is changed, so that the amount of liquid pumped and pressed by the piston block in the filling barrel can be adjusted.

DETAILED DESCRIPTION

[0020] The following describes embodiments of the present invention with reference to the accompanying drawings.

[0021] Example: An acid-base resistant and metal-free photovoltaic liquid additive automatic filling device, such as Figures 1-4As shown, it includes a mounting frame 1, a storage cylinder 2 and a filling cylinder 3. The mounting frame 1 is a supporting carrier of the filling device. The storage cylinder 2 is installed on one side of the mounting frame 1. The storage cylinder 2 is used for temporarily storing or replenishing additives. The filling cylinder 3 is installed on the other side of the mounting frame 1. The filling cylinder 3 is used for automatically filling additives. The storage cylinder 2 and the filling cylinder 3 are both made of non-metallic materials that do not react with photovoltaic liquid additives. The bottoms of the storage cylinder 2 and the filling cylinder 3 are connected through a connecting pipe 21. A one-way valve 22 is provided on the connecting pipe 21. A liquid outlet pipe 31 is provided on one side of the filling cylinder 3. There is a one-way valve 32; it also includes: a hopper 4, which is arranged at the top opening of the storage cylinder 2; a mounting plate 5, which is symmetrically fixed to the side of the mounting frame 1 close to the filling cylinder 3; a rotating shaft 6, which is rotatably installed between the two mounting plates 5; a motor 7, which is installed on one of the mounting plates 5, and the output shaft of the motor 7 passes through the mounting plate 5 and is connected to the rotating shaft 6; two turntables 8, which are set as a group and symmetrically installed on the rotating shaft 6; a first connecting rod 10, which is hinged between the two turntables 8, and the hinge point of the first connecting rod 10 and the turntable 8 is eccentrically set; a piston block 11, which is sealed and slidably arranged inside the filling cylinder 3, and is movable A piston structure is formed between the plug block 11 and the filling barrel 3; the second connecting rod 12 is connected to the top surface of the piston block 11, and the lower end of the first connecting rod 10 and the upper end of the second connecting rod 12 are hinged. A piston structure is formed between the piston block 11 and the filling barrel 3. When the motor 7 drives the turntable 8 to rotate, the turntable 8 will alternately drive the first connecting rod 10 and the second connecting rod 12 up and down to perform a lifting and reciprocating motion. The piston block 11 on the second connecting rod 12 performs a piston motion in the filling barrel 3, and cooperates with the one-way action of the one-way valve 22 and the one-way valve 2 32 to enable the additive in the storage barrel 2 to be alternately drawn into After the filling cylinder 3 is filled, the additive is poured and discharged from the liquid outlet pipe 31 of the filling cylinder 3; the one-way valve 1 22 on the connecting pipe 21 allows the storage cylinder 2 to unidirectionally connect to the filling cylinder 3, and the one-way valve 2 32 on the liquid outlet pipe 31 allows the inside of the filling cylinder 3 to unidirectionally connect to the outside. When the piston block 11 in the filling cylinder 3 rises, the one-way valve 2 32 cannot be conducted and the one-way valve 1 22 is conducted, so that the additive in the storage cylinder 2 is injected into the filling cylinder 3. When the piston block 11 in the filling cylinder 3 descends, the one-way valve 2 32 is conducted and the one-way valve 1 22 cannot be conducted, so that the additive in the filling cylinder 3 is discharged from the liquid outlet pipe 31 for automatic filling.

[0022] like Figure 1 and Figure 4As shown, the turntable 8 is also provided with an adjusting member, which includes a slider 9, a card ball 13 and a spring 14. There are sliding grooves on the turntable 8, and the slider 9 is slidably installed in the sliding groove of the turntable 8. The first connecting rod 10 is hinged to the turntable 8 through the slider 9. Multiple groups of card balls 13 are symmetrically slidably installed on both sides of the sliding groove of the turntable 8. A card hole adapted for the card ball 13 is opened on the side wall of the slider 9. A spring 14 is provided between the card ball 13 and the turntable 8. By sliding the adjusting slider 9 in the sliding groove of the turntable 8, the card ball 13 is snapped into the card hole of the slider 9 under the action of the spring 14, so that the stroke of the first connecting rod 10 and the second connecting rod 12 driven by the turntable 8 is changed, so that the amount of liquid extraction and pressure injection of the piston block 11 in the filling barrel 3 can be adjusted.

[0023] like Figure 1 and Figure 2 As shown, it also includes a telescopic tube 15 and a filling head 17. The outlet end of the liquid outlet pipe 31 is installed with the telescopic tube 15, which is made of flexible material and has elasticity. The filling head 17 is installed at the outlet of the telescopic tube 15. The nozzle of the filling head 17 is small and can adapt to the filling work of more delicate additives. By holding the filling head 17 and adjusting the telescopic tube 15 by telescoping, the photovoltaic liquid additive can be conveniently poured; the telescopic tube 15 is detachably installed at the outlet of the liquid outlet pipe 31, and the filling head 17 at the outlet of the telescopic tube 15 is also replaceable. According to the actual filling needs of the additive, the corresponding filling head 17 and the telescopic tube 15 can be flexibly replaced, and the telescopic tube 15 and the filling head 17 can be conveniently cleaned and maintained after being disassembled from each other.

[0024] like Figure 2 As shown, a clamping block 16 is also included. A clamping block 16 is installed on a side wall of the top of the mounting frame 1 close to the filling barrel 3. The clamping block 16 is an arc clamping block. The clamping block 16 is used to clamp the telescopic tube 15 so that the telescopic tube 15 and the filling head 17 can be conveniently placed when not in use, thereby improving the convenience of the device when in use.

[0025] When the device performs the filling operation of adding photovoltaic liquid, the photovoltaic liquid additive is first added to the storage cylinder 2 through the hopper 4. The storage cylinder 2 serves as a temporary storage or supplementary container for the additive. When the filling operation is required, the motor 7 is started, and its output shaft drives the rotating shaft 6 to rotate, thereby causing the two turntables 8 installed on the rotating shaft 6 to rotate synchronously. Since the hinge point of the first connecting rod 10 and the turntable 8 is eccentrically set, as the turntable 8 rotates, the first connecting rod 10 will perform an alternating up and down reciprocating motion, and the first connecting rod 10 will drive the second connecting rod 12 to reciprocate. The piston block 11 moves and transmits it to the piston block 11 inside the filling barrel 3 through the second connecting rod 12, so that the piston block 11 performs reciprocating piston motion in the filling barrel 3. When the piston block 11 moves upward, negative pressure is formed inside the filling barrel 3, the one-way valve 1 22 is smoothly opened and the one-way valve 2 32 cannot be opened, and the additive in the storage barrel 2 is sucked into the filling barrel 3. On the contrary, when the piston block 11 moves downward, the pressure inside the filling barrel 3 increases, the one-way valve 1 22 cannot be opened and the one-way valve 2 32 is smoothly opened. After the additive in the filling barrel 3 is squeezed out, the one-way valve 1 22 is opened and the one-way valve 2 32 is opened. The liquid is finally ejected from the filling head 17 through the liquid outlet pipe 31 and the telescopic tube 15 to complete the automatic filling process of the additive. In addition, by adjusting the position of the slider 9 on the turntable 8, after turning off the motor 7, the user uses a tool to slide and adjust the slider 9 on the turntable 8. When the slider 9 slides and adjusts and aligns with the corresponding position of the card ball 13, the card ball 13 pops out under the action of the spring 14 and is stuck on the card hole on the slider 9, so that the slider 9 is limited to the required position of the turntable 8, thereby adjusting the eccentricity of the first connecting rod 10 hinged on the turntable 8, thereby changing the first connecting rod 10. The stroke of the rod 10 and the second connecting rod 12 adjusts the amount of liquid drawn and pressed by the piston block 11 in the filling barrel 3 to meet the needs of different filling volumes. The use of the telescopic tube 15 not only increases the flexibility of the filling head 17, enabling it to adapt to different filling positions, but also makes it easy to fix it through the block 16 when not in use to keep the device tidy. Finally, the telescopic tube 15 and the filling head 17 are both detachable designs, which makes it convenient for users to replace different filling heads 17 according to actual needs, and to clean and maintain them after use, ensuring the long-term stable operation of the device.
