Description

Technical Field

[0001] This utility model relates to the field of sampling technology, and more particularly to a sampling device for photovoltaic liquid additives without metal contact. Background Technology

[0002] Metal-free photovoltaic liquid additives refer to liquid additives that do not contain metal components and are used in the manufacture or maintenance of photovoltaic modules. These additives have a wide range of applications, aiming to improve the efficiency of photovoltaic modules, extend their lifespan, optimize manufacturing processes, or enhance module cleanliness.

[0003] To ensure the quality of additives, sampling and testing are typically required during the production process. Existing sampling methods mostly rely on manual operation, using various sampling tools to collect samples from the additives. However, this method is prone to contamination of the additives by external impurities during sampling, and the dispersed distribution of sampling equipment makes efficient centralized sampling difficult. This not only affects the accuracy of the sampling but may also adversely impact the overall quality of the additives.

[0004] Given the above challenges, there is an urgent need to develop a metal-free photovoltaic liquid additive sampling device that can achieve efficient and centralized sampling while maintaining closed sampling of the additive, so as to ensure the accuracy and reliability of the sampling results and thus guarantee the product quality of the additive. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a non-metal-contact photovoltaic liquid additive sampling device that can achieve efficient and centralized sampling while maintaining the closed sampling of additives, so as to ensure the accuracy and reliability of the sampling results and thus guarantee the product quality of additives.

[0006] The technical solution is as follows: A non-metallic photovoltaic liquid additive sampling device includes a box body, a cover plate, rodless cylinders, a connecting frame, a pressure plate, a support rod, a baffle, and a sampler. A placement chamber is located in the middle of the box body. From the center of the placement chamber, an assembly chamber and two sampling chambers are arranged on either side. The assembly chambers are located on both sides of the placement chamber. A cover plate is rotatably mounted on the box body to cover the four sampling chambers and the placement chamber. Two rodless cylinders are installed in each of the two assembly chambers. A connecting frame is connected to the slider of each rodless cylinder, and a pressure plate is connected to the end of each connecting frame. The pressure plate matches the opening of the sampling chamber and slides with the adjacent sampling chamber. A through hole is opened in the middle of each pressure plate, and a support rod is mounted on each pressure plate. A baffle is rotatably mounted on the support rod to block the through hole, and a sampler capable of extending into the corresponding sampling chamber is inserted into each baffle.

[0007] Preferably, the device also includes a mounting bracket and a wiping bar, with a vertical mounting bracket on the connecting bracket and a wiping bar rotatably mounted on the mounting bracket for wiping the sampler after sampling.

[0008] Preferably, the sample also includes a partition rack, which is provided in the placement chamber to facilitate the placement of samples.

[0009] Preferably, a sponge pad is also included, with a sponge pad provided at the bottom of the placement chamber to cushion the pressure of sample placement.

[0010] Preferably, the box also includes a handle, which is symmetrically arranged between the two sides of the box for easy gripping.

[0011] As a preferred option, it also includes a non-slip sleeve, with a non-slip sleeve fitted on the handle.

[0012] The beneficial effects of this utility model are as follows: By using a rodless cylinder to drive the corresponding pressure plate to move up and down, the sealing between the pressure plate and the sampling chamber can be precisely controlled, ensuring that no leakage or cross-contamination occurs during the sampling process, thus improving the accuracy and reliability of sampling. Furthermore, the cooperation of multiple sampling chambers and samplers allows for the simultaneous sampling of multiple samples, reducing the time required for manual operation and greatly improving the efficiency of the sampling work.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example: A non-metal-contact photovoltaic liquid additive sampling device, such as... Figures 1-5 As shown, the device includes a box body 1, a cover plate 3, rodless cylinders 4, a connecting frame 5, a pressure plate 6, a support rod 7, a baffle 8, and a sampler 9. The box body 1 is hollow and mainly used to accommodate and protect the internal components. A placement chamber 102 is located in the center of the box body 1. From the center of the placement chamber 102, an assembly chamber 103 and two sampling chambers 101 are respectively arranged on the left and right sides of the placement chamber 102. A cover plate 3 is rotatably mounted on the box body 1 to cover the four sampling chambers 101 and the placement chambers 102, helping to keep the interior clean and prevent external contamination. Two rodless cylinders 4 are longitudinally fixedly installed in each of the two assembly chambers 103. A connecting frame 5 is connected to the slider of each rodless cylinder 4, and a pressure plate 6 is connected to the end of each connecting frame 5. The pressure plate 6 matches the opening of the sampling chamber 101. The adjacent sampling chambers 101 slide together, and driven by the rodless cylinder 4, the pressure plate 6 can move up and down precisely, thereby automatically closing or opening the sampling chamber 101 to prevent sample leakage. At the same time, it provides a more closed and clean working environment for subsequent sampling operations. Each pressure plate 6 has a through hole in the middle, so that when the pressure plate 6 is pressed down, the air inside the sampling chamber 101 can be vented accordingly to ensure the accuracy of subsequent sampling. Each pressure plate 6 is equipped with a support rod 7, and a cover 8 is rotatably installed on the support rod 7 to block the through hole. Each cover 8 is equipped with a sampler 9 that can extend into the corresponding sampling chamber 101. The sampler 9 is a tool used to extract photovoltaic liquid additives from the sampling chamber 101. It can be replaced and removed. By using multiple sampling chambers 101 and multiple samplers 9 for sampling operations, the overall sampling process can be more centralized, thereby improving work efficiency and reducing personnel burden.

[0021] like Figure 5 As shown, it also includes a mounting frame 10 and a wiping rod 11. The connecting frame 5 is provided with a vertical mounting frame 10, and the mounting frame 10 is rotatably provided with a wiping rod 11 for wiping the sampler 9 after sampling, so as to reduce the risk of cross-contamination.

[0022] like Figure 3 and Figure 4 As shown, it also includes a partition rack 1021, which is provided in the placement chamber 102 to facilitate the placement of samples.

[0023] like Figure 4As shown, it also includes a sponge pad 1022. A sponge pad 1022 is provided at the bottom of the placement chamber 102 to buffer the pressure of sample placement, thereby protecting the sample from damage.

[0024] like Figure 1 As shown, it also includes a handle 2, which is symmetrically arranged between the front and rear sides of the box body 1 for easy gripping.

[0025] like Figure 1 As shown, it also includes an anti-slip sleeve 201. The handle 2 is covered with an anti-slip sleeve 201, which can increase the comfort and stability when holding the handle 2.

[0026] When sampling photovoltaic liquid additives without metal contact, first open each of the cover plates 3 on the device in sequence. Next, activate the rodless cylinder 4, which will move the connecting frame 5 and pressure plate 6 upwards, opening the sampling chamber 101. Then, accurately place the additive to be sampled into the designated sampling chamber 101. As the rodless cylinder 4 drives the component downwards again, the pressure plate 6 descends and embeds itself into the sampling chamber 101. At this time, the through hole on the pressure plate 6 is not blocked by the cover 8, which helps to expel air from the sampling chamber 101 during the downward pressing of the pressure plate 6. When the pressure plate 6 reaches the appropriate sampling position, manually rotate the cover 8 above the through hole of the pressure plate 6 to ensure a seal. In this way, the sampler 9 can be safely inserted into the cover 8. Due to the sealed environment formed by the pressure plate 6 and the sampling chamber 101, the sampling process can be effectively protected from external interference. After sampling is completed, the sampler 9 is removed from the cover 8, and then the wiping rod 11 is rotated to wipe the surface of the sampler 9 to remove any remaining impurities. The sampler 9 is then securely stored in the placement chamber 102, with each sample separated by a partition rack 1021, and a sponge pad 1022 providing additional protection for the samples. After the entire sampling process is completed, all covers 3 are closed, and the entire device is smoothly moved to the detection area using the handle 2.

[0027] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
