Description
Technical Field
[0001] The utility model relates to the technical field of power distribution equipment detection, in particular to a high-voltage short-circuit detection device. Background Art
[0002] In the electronic equipment and battery manufacturing industries, short-circuit detection of batteries and other electrical components is a crucial step in ensuring product quality and safety. Short-circuit detection can promptly identify potential electrical faults and prevent fires, explosions, and other safety incidents caused by short circuits. However, existing short-circuit detection methods and technologies still have some challenges and shortcomings in practical applications.
[0003] First, traditional short-circuit detection methods often rely on manual labor, which is not only inefficient but also susceptible to human error, making it difficult to ensure the accuracy and consistency of test results. Furthermore, manual labor carries safety risks, especially when handling high-voltage equipment. Any accidents can have disastrous consequences.
[0004] While some automated short-circuit detection equipment has improved detection efficiency, it still has limitations in design and functionality. For example, some devices cannot precisely control the force and position of the test during the test, resulting in damage to the device being tested or misinterpretation of the test results. Furthermore, some devices have limited applicability and cannot adapt to different specifications and types of devices being tested. Utility Model Content
[0005] The utility model aims at the technical problems existing in the prior art and provides a high-voltage short-circuit detection device to solve the problems of poor safety and low efficiency of short-circuit detection of high-voltage equipment.
[0006] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a high-voltage short-circuit detection device, comprising a main detection platform, on which a conveyor for equipment to be detected is mounted; the main detection platform is also provided with a lifting platform located above the conveyor for equipment to be detected, and a lifting mechanism connected to the lifting platform; a battery cell isolation seat is installed below the lifting platform, on which a high-voltage battery cell for short-circuiting the equipment to be detected is mounted; when the conveyor for equipment to be detected transports the equipment to be detected to the detection area, the lifting mechanism drives the lifting platform down to allow the high-voltage battery cell to short-circuit the equipment to be detected.
[0007] On the basis of the above technical solution, the present invention can also be improved as follows.
[0008] Furthermore, limit frames are provided on both sides of the conveying direction of the conveyor of the equipment to be inspected.
[0009] Furthermore, a plurality of guide wheels arranged at equal intervals are continuously arranged on the limiting frame.
[0010] Furthermore, positioning cylinders are provided on both sides of the detection area along the conveyor of the equipment to be detected.
[0011] Furthermore, the lifting mechanism includes:
[0012] A lifting cylinder installed on the main inspection platform and connected to the lifting platform;
[0013] A guide rod that slides with the main inspection platform and is connected to the lifting platform.
[0014] Furthermore, the lifting mechanism also includes a fine calibration cylinder arranged between the lifting platform and the battery cell isolation seat.
[0015] Furthermore, a temporary testing platform is provided on one side of the unloading end of the conveyor of the equipment to be tested, and a pushing cylinder for pushing the problematic equipment to the temporary testing platform is provided along the other side of the equipment conveyor.
[0016] Furthermore, the high-voltage short-circuit detection device provided by the present invention has at least the following beneficial effects compared to the prior art:
[0017] 1. The high-voltage short-circuit detection device of this utility model significantly improves detection efficiency and safety. Through automated control, the device can automatically complete the transportation, positioning, short-circuit detection, and isolation of the equipment to be tested, greatly reducing the need for manual operation and thus avoiding detection errors and safety risks caused by human factors. In addition, the automated process speeds up detection, improves production efficiency, and ensures timely verification of product quality and safety.
[0018] 2. The combined design of the limit frame and guide wheels ensures the stability of the equipment to be tested during transportation, reducing deviation and shaking. The precise control of the positioning cylinder enables the precise positioning and fixation of the equipment to be tested in the test area, further improving the accuracy of short-circuit detection. At the same time, the fine calibration cylinder in the lifting mechanism provides a fine-tuning function to ensure the precise docking between the high-voltage battery cell and the equipment to be tested, avoiding misjudgment or equipment damage due to position deviation. In addition, the setting of the temporary test table and the push cylinder enables the problem equipment to be quickly isolated and further processed, avoiding interruption of the detection process and improving the overall detection efficiency.

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0025] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integrated structures. Those skilled in the art will understand the specific meanings of such terms in this patent based on specific circumstances.
[0026] like Figure 1-Figure 3 As shown, the high-voltage short-circuit detection device of the present utility design includes a main detection platform 1, on which a conveyor 2 for equipment to be detected is mounted; the main detection platform 1 is also provided with a lifting platform 3 located above the conveyor 2 for equipment to be detected, and a lifting mechanism 4 connected to the lifting platform 3; a battery cell isolation seat 5 is installed below the lifting platform 3, and a high-voltage battery cell 6 for short-circuiting the equipment to be detected is installed on the battery cell isolation seat 5; when the conveyor 2 for equipment to be detected transports the equipment to be detected to the detection area, the lifting mechanism 4 drives the lifting platform 3 to descend so that the high-voltage battery cell 6 short-circuits the equipment to be detected.
[0027] As an implementation method, limit frames 7 are further provided along both sides of the conveying direction of the conveyor 2 of the device to be inspected.
[0028] Specifically, a plurality of guide wheels 8 arranged at equal intervals are continuously arranged on the limiting frame 7 .
[0029] The combination of the positioning frame 7 and the guide wheels 8 forms a stable conveying system for the equipment under inspection on conveyor 2. The positioning frame 7 provides a basic positioning function, preventing the equipment from shifting significantly during conveyance, while the guide wheels 8 further improve conveying stability and accuracy through rolling friction.
[0030] As an embodiment, positioning cylinders 9 are provided on both sides of the detection area of the conveyor 2 of the device to be detected.
[0031] When the device to be inspected is transported to the inspection area via conveyor 2, the control system detects the device's arrival and triggers the action of positioning cylinder 9. Upon receiving the control signal, positioning cylinder 9 quickly extends its piston rod, pushing the positioning device (such as a positioning block, clamping claw, etc.) in contact with the device to be inspected toward the device.
[0032] As the positioning cylinder 9 moves further, the positioning device will tightly clamp or press against the specific part of the device to be tested, thereby achieving accurate positioning and fixation of the device.
[0033] As an embodiment, the lifting mechanism 4 includes:
[0034] A lifting cylinder 4.1 installed on the main testing platform 1 and connected to the lifting platform 3;
[0035] A guide rod 4.2 that is in sliding engagement with the main inspection platform 1 and connected to the lifting platform 3.
[0036] Specifically, the lifting mechanism 4 further includes a fine calibration cylinder 4.3 arranged between the lifting platform 3 and the battery cell isolation seat 5.
[0037] Fine calibration cylinder 4.3, positioned between lift platform 3 and cell isolation holder 5, is used for fine adjustments once lift platform 3 reaches its approximate position. Because lift cylinder 4.1 may have limited travel and accuracy, fine calibration cylinder 4.3 further precisely controls the position of cell isolation holder 5 and high-voltage battery cell 6, ensuring they accurately contact the device under test. As lift platform 3 approaches its target position, fine calibration cylinder 4.3 activates and slowly adjusts the position of cell isolation holder 5 until the high-voltage battery cell 6 is precisely aligned with the device under test.
[0038] As an embodiment, a temporary testing platform 10 is further provided on one side of the unloading end of the equipment conveyor 2 to be tested, and a pushing cylinder 11 for pushing the problematic equipment to the temporary testing platform 10 is further provided along the other side of the equipment conveyor 2.
[0039] The equipment to be inspected is continuously transported on the conveyor 2 and passes through various inspection points (such as short-circuit inspection points) in sequence. When a problem is detected in a piece of equipment, the control system will immediately identify it and trigger the action of the push cylinder 11. The push cylinder 11 quickly pushes the problematic equipment out of the conveyor 2 and guides it to the temporary inspection station 10 through a preset path. On the temporary inspection station 10, staff can further inspect, repair or record the problematic equipment without interfering with the inspection process of other normal equipment on the conveyor 2.
[0040] The working principle of this utility model is as follows:
[0041] The device uses a main testing platform 1 as the operating platform, on which is located a device conveyor 2 for automatically transporting the electrical equipment to be tested to the designated testing area. Above the device conveyor 2, the device is equipped with a lifting platform 3, which is precisely controlled by a lifting mechanism 4 to achieve vertical movement.
[0042] A cell isolation seat 5 is installed below the lifting platform 3, and a high-voltage cell 6 is fixed on the cell isolation seat 5. The high-voltage cell 6 is a key component in the detection process and is used to contact a specific part of the device to be tested to simulate or actually produce a short circuit state.
[0043] After the device to be inspected is accurately delivered to the inspection area by conveyor 2, lifting mechanism 4 receives a control signal and begins operating, driving lifting platform 3 and its underlying battery cell isolation holder 5 and high-voltage battery cell 6 downward. As lifting platform 3 descends, high-voltage battery cell 6 gradually approaches and eventually contacts the corresponding part of the device to be inspected, creating a short circuit.
[0044] In a short-circuit state, the detection system monitors and records changes in electrical parameters such as current and voltage. These changes can reflect the electrical performance of the device under short-circuit conditions and determine whether a short-circuit fault exists.
[0045] If the device under test exhibits normal electrical performance during the short-circuit test—that is, parameters such as current and voltage fluctuate within a preset range—the system will determine that the device has passed the test. Conversely, if the parameters are abnormal, it indicates a short-circuit fault and triggers an appropriate alarm or recording mechanism.
[0046] It should be noted that, in this article, the terms "include", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device. Unless otherwise expressly specified and limited, the terms "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be internal communication between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0047] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
[0048] 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.
