Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic equipment technology, specifically to a magnetic induction switch device for alarming the pressure basket and loss of baskets in corrosive environments. Background Art

[0002] Photovoltaic power generation is based on the photovoltaic effect principle, which uses solar cells to directly convert sunlight into electrical energy. Whether used independently or connected to the grid, a photovoltaic power generation system mainly consists of three parts: solar panels (modules), controllers, and inverters.

[0003] During the production of solar panels, the liquid contained in the solar panel manufacturing equipment releases a large amount of acidic or alkaline gases. Therefore, lifting devices are needed to place the solar panels into and remove them from the liquid environment for the next process. Existing lifting devices include hooks and baskets. The solar panels are placed in the baskets, and the hooks engage with the hanging rings on the baskets to move the baskets up and down synchronously, thus enabling the placement and removal of the solar panels from the liquid environment. However, two abnormal states can easily occur during the interaction between the hooks and the baskets: basket loss during lifting and basket crushing during unloading. The basket loss during lifting leaves the hooks unloaded, and the solar panels are not transferred; the basket crushing during unloading damages the basket. In current technology, the detection of these two abnormal states still relies on manual identification by operators, resulting in low automation and difficulty in manual detection. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a magnetic induction switch device for alarming the pressing and losing of baskets in corrosive environments, so as to solve the problem that the hooks and baskets need to be manually identified when they are in abnormal state, resulting in low automation and difficulty in detection.

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0006] This application provides a magnetic induction switch device for alarming basket pressure and loss in corrosive environments. The magnetic induction switch device includes a hook and a hanging basket, with the hanging basket disposed below the hook. The magnetic induction switch device also includes a magnetic sensor and a movable lifting rod. The magnetic sensor is disposed inside the hook, and the movable lifting rod is vertically slidably connected to the hook. The movable lifting rod has a first magnetic segment, a non-magnetic segment, and a second magnetic segment arranged sequentially from top to bottom. The bottom end of the movable lifting rod abuts against the top end of the hanging basket. When the hook and the hanging basket are in a normal basket lifting and transfer state, the non-magnetic segment moves to the magnetic sensor. When the hook and the hanging basket are in a basket lifting and transfer state where the basket is lost or in a basket pressing state during the basket placement process, the first magnetic segment and the second magnetic segment respectively move to the magnetic sensor.

[0007] Furthermore, the movable lifting rod is a magnetic rod. A first magnetic shielding sleeve is fitted onto the upper outer circumference of the movable lifting rod, forming the non-magnetic segment. A second magnetic shielding sleeve is fitted onto the lower outer circumference of the movable lifting rod. The top of the movable lifting rod and the first magnetic shielding sleeve form the first magnetic segment. The area on the movable lifting rod located at the bottom of the first magnetic shielding sleeve and the top of the second magnetic shielding sleeve forms the second magnetic segment.

[0008] Furthermore, the magnetic induction switch device also includes a first mounting base and a second mounting base, which are respectively horizontally fixedly installed at the upper and lower ends of the inner side of the hook. The movable lifting rod is vertically slidably installed on the first mounting base and the second mounting base, and the magnetic sensor is fixedly installed on the first mounting base.

[0009] Furthermore, both the first and second magnetic shielding sleeves are made of plastic.

[0010] The beneficial effects of this utility model are as follows:

[0011] The system features a movable lifting rod that is vertically connected to the hook. This lifting rod has a first magnetic section, a non-magnetic section, and a second magnetic section arranged sequentially from top to bottom. When the hook engages with the hanging ring on the basket, the top of the basket contacts the bottom of the lifting rod. Under normal conditions, the non-magnetic section is aligned with the magnetic sensor, and the sensor does not detect any magnetic material and therefore does not respond. However, when the hook and basket are in either a lost or pressed state, the corresponding first and second magnetic sections are aligned with the magnetic sensor, triggering an alarm. This highly automated system allows for timely intervention by the operator. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0018] See attached Figure 1 As shown, this embodiment provides a magnetic induction switch device 100 for pressing baskets and alarming lost baskets in corrosive environments. It includes a hook 10, a hanging basket 20, a magnetic sensor 60, and a movable lifting rod 50. The hanging basket 20 is located below the hook 10. The hook 10 is used to cooperate with the hanging ring on the hanging basket 20 so that the hook 10 can lift the hanging basket 20.

[0019] Continue to refer to the appendix Figure 1 As shown, the magnetic sensor 60 is fixedly installed inside the hook 10, and the movable lifting rod 50 is also installed inside the hook 10, and the movable lifting rod 50 can move up and down relative to the hook 10 in the height direction. The movable lifting rod 50 has a first magnetic segment 51, a non-magnetic segment 52, and a second magnetic segment 53 arranged sequentially from its top to its bottom. When the magnetic segment (first magnetic segment 51 or second magnetic segment 53) is at the same horizontal position as the magnetic sensor 60, the magnetic sensor 60 will generate a corresponding response (trigger an alarm) when it detects a magnetic substance. However, when the non-magnetic segment 52 is at the same horizontal position as the magnetic sensor 60, the magnetic sensor 60 will not respond.

[0020] Refer to the attached Figure 1As shown, when the hanging basket 20 is hung on the hook 10, under normal conditions, the top of the hanging basket 20 is in contact with the bottom of the movable lifting rod 50, and the non-magnetic section 52 on the movable lifting rod 50 is in the same position as the magnetic sensor 60. At this time, the magnetic sensor 60 will not respond (alarm) because it does not detect magnetism.

[0021] Refer to the attached Figure 2 As shown, when the hook 10 and the hanging basket 20 are used together, if the basket is lost during the transfer (the hanging basket 20 and the hook 10 are separated), since the bottom end of the movable lifting rod 50 is not in contact with the top end of the hanging basket 20, the movable lifting rod 50 falls under its own weight (it can be understood that the top end of the movable lifting rod 50 forms a limit structure), causing the first magnetic segment 51 located at the top end of the movable lifting rod 50 to be at the same horizontal position as the magnetic sensor 60. The magnetic sensor 60 detects the magnetic material and issues an alarm response to remind the operator to handle the situation.

[0022] Refer to the attached Figure 3 As shown, when the hook 10 and the hanging basket 20 are used together, during the basket placement process, the basket is pressed (the hanging basket 20 is squeezed). Because the bottom end of the movable lifting rod 50 is squeezed by the top end of the hanging basket 20 below, the second magnetic segment 53 at the bottom of the movable lifting rod 50 moves upward (the bottom end of the movable lifting rod 50 also forms a limit structure, which limits the distance the movable lifting rod 50 can move upward, ensuring that when the bottom end of the movable lifting rod 50 is subjected to upward squeezing force and moves upward, the second magnetic segment 53 just moves to the position of the magnetic sensor 60) and is in the same position as the magnetic sensor 60. At this time, the magnetic sensor 60 detects the magnetic material and makes an alarm response to remind the operator to handle it.

[0023] Refer to the attached Figure 1 As shown, a first mounting base 30 and a second mounting base 40 are horizontally fixedly installed at the upper and lower ends of the inner side of the hook 10, respectively. The movable lifting rod 50 is vertically slidably installed on the first mounting base 30 and the second mounting base 40, and the magnetic sensor 60 is fixedly installed on the first mounting base 30.

[0024] Continue to refer to the appendix Figure 1As shown, in this embodiment, the movable lifting rod 50 is a magnetic rod. A first magnetic shielding sleeve 70 is fitted onto the upper outer periphery of the movable lifting rod 50, forming magnetic shielding over the area it covers. Specifically, the area covered by the first magnetic shielding sleeve 70 forms a non-magnetic segment 52. A second magnetic shielding sleeve 80 is fitted onto the lower outer periphery of the movable lifting rod 50. The top of the movable lifting rod 50 and the first magnetic shielding sleeve 70 form the aforementioned first magnetic segment 51. The area on the movable lifting rod 50 located at the bottom of the first magnetic shielding sleeve 70 and the top of the second magnetic shielding sleeve 80 forms the aforementioned second magnetic segment 53. In some embodiments, the first magnetic shielding sleeve 70 and the second magnetic shielding sleeve 80 are made of plastic.

[0025] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
