Technical Field

[0001] This utility model relates to the field of safety protection technology for plasma power supplies, and in particular to a safety protection device for plasma power supplies. Background Technology

[0002] A plasma power source is a special type of power supply device whose main function is to convert gas into a high-energy plasma state, thereby meeting the needs of various experimental research and practical applications.

[0003] Currently, the focus of protective measures is on the reliability of electrical isolation and the accuracy of temperature control, laying a solid foundation for the safe operation of plasma power supplies. However, at the level of mechanical safety protection, especially in preventing accidental collisions, there is still room for improvement. Accidental collisions can lead to physical damage to the plasma power supply, performance degradation, or even safety accidents.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a safe plasma power supply protection device to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a safe plasma power supply protection device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A safety plasma power supply protection device includes a lower base plate, support columns, and an upper base plate. Multiple support columns are fixedly connected between the lower and upper base plates. A groove is formed at the upper end of the lower base plate, and two symmetrically distributed receiving plates are slidably connected within the groove. A thrust assembly is connected between the two receiving plates, driving the two receiving plates to move away from or closer to each other. A second rotating plate is rotatably connected to one end of each receiving plate. A baffle is fixedly connected to one side of the second rotating plate, and a third rotating plate is rotatably connected to the other side of the second rotating plate. A buffer assembly is fitted between the third rotating plate and its corresponding receiving plate.

[0008] A further technical solution involves fixing warning signs to one end of each baffle.

[0009] A further technical solution includes a thrust assembly comprising a support plate, a threaded rod, a threaded sleeve, a connecting lug, a first rotating plate, and a fixed shaft; two symmetrically distributed support plates are fixedly connected to the upper surface of the lower base plate, and a threaded rod is rotatably connected between the two support plates; a threaded sleeve is threadedly connected to the outer wall of the threaded rod, and two symmetrically distributed connecting lugs are fixedly connected to the outer wall of the threaded sleeve; a fixed shaft is fixedly connected to each receiving plate, and a first rotating plate is rotatably connected to the outer wall of the fixed shaft, with the other end of the first rotating plate rotatably connected to the corresponding connecting lug.

[0010] A further technical solution involves fixing a knob to one end of the threaded sleeve that passes through the support plate.

[0011] A further technical solution is provided, wherein the buffer assembly includes a buffer chamber, a buffer block, a buffer spring, a limiting groove, and a limiting strip; buffer chambers are fixedly connected to the receiving plate, buffer blocks are slidably connected to the inner wall of the buffer chamber, and a buffer spring is fixedly provided between the buffer block and the inner wall of the buffer chamber near the threaded rod, and the upper end of the buffer block is rotatably connected to the third rotating plate.

[0012] A further technical solution involves creating a limiting groove on the inner wall of the buffer chamber, and fixing limiting strips to both sides of the buffer block, with the limiting strips slidably connected to the limiting grooves.

[0013] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0014] 1. By fixing and affixing warning signs to one end of the baffle, operators and other personnel are reminded to maintain a safe distance. When the baffle is hit, the baffle pushes the second rotating plate to rotate, and then the second rotating plate pushes the buffer assembly to move through the third rotating plate. The third rotating plate is simultaneously subjected to the reverse thrust of the buffer assembly, and this thrust gradually increases. The third rotating plate applies a gradually increasing reverse thrust to the baffle through the second rotating plate, which can effectively reduce the impact force of the collision and protect the plasma power supply equipment from sudden impact damage.

[0015] 2. By driving the two receiving plates to move away from or closer to each other through the thrust assembly, the space occupied by the entire device can be flexibly adjusted, making the device suitable for different sized spaces and improving its versatility and practicality.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] like Figure 1-3 As shown, this utility model embodiment provides a safe plasma power supply protection device, including a lower base plate 1, support columns 2, and an upper base plate 3. Multiple support columns 2 are fixedly connected between the lower base plate 1 and the upper base plate 3. A plasma power supply is fixedly installed on the upper base plate 3. A groove 6 is provided at the upper end of the lower base plate 1. Two symmetrically distributed receiving plates 7 are slidably connected within the groove 6. A thrust assembly 8 is connected between the two receiving plates 7. The thrust assembly 8 is used to drive the two receiving plates 7 to move away from or towards each other. A second rotating plate 9 is rotatably connected to one end of each receiving plate 7. A baffle 4 is fixedly connected to one side of the second rotating plate 9. A third rotating plate 10 is rotatably connected to the other side of the second rotating plate 9. A buffer assembly 11 is fitted between the third rotating plate 10 and the corresponding receiving plate 7. The cooperation between the buffer assembly 11 and the third rotating plate 10 allows the baffle 4 to push the second rotating plate 9 to rotate, and the second rotating plate 9 is subjected to a gradually increasing reverse thrust.

[0024] Furthermore, warning signs 5 are fixedly affixed to one end of each baffle 4 to remind operators and other personnel to maintain a safe distance.

[0025] Specifically, by fixing and affixing a warning sign 5 to one end of the baffle 4, operators and other personnel are reminded to maintain a safe distance 4. When the baffle 4 is impacted, the baffle 4 pushes the second rotating plate 9 to rotate. Then, the second rotating plate 9 pushes the buffer assembly 11 to move through the third rotating plate 10. Simultaneously, the third rotating plate 10 is subjected to the reverse thrust of the buffer assembly 11, and this thrust gradually increases. The third rotating plate 10 applies a gradually increasing reverse thrust to the baffle 4 through the second rotating plate 9, which can effectively reduce the impact force of the collision and protect the plasma power supply equipment from sudden impact damage. By driving the two receiving plates 7 to move away from or closer to each other through the thrust assembly 8, the space occupied by the plasma power supply protection device can be flexibly adjusted, making the plasma power supply protection device suitable for space environments of different sizes, thus improving its versatility and practicality.

[0026] like Figure 1 and Figure 2 As shown, the thrust assembly 8 includes a support plate 81, a threaded rod 82, a threaded sleeve 83, a connecting lug 84, a first rotating plate 85, and a fixed shaft 86; two symmetrically distributed support plates 81 are fixedly connected to the upper end face of the lower base plate 1, and a threaded rod 82 is rotatably connected between the two support plates 81. A threaded sleeve 83 is threadedly connected to the outer wall of the threaded rod 82, and two symmetrically distributed connecting lugs 84 are fixedly connected to the outer wall of the threaded sleeve 83; a fixed shaft 86 is fixedly connected to each of the receiving plates 7, and a first rotating plate 85 is rotatably connected to the outer wall of the fixed shaft 86, and the other end of the first rotating plate 85 is rotatably connected to the corresponding connecting lug 84.

[0027] Furthermore, the threaded sleeve 83 and the connecting lug 84 are an integral structure.

[0028] Furthermore, a knob 87 is fixedly connected to one end of the threaded sleeve 83 that passes through the support plate 81.

[0029] Specifically, the rotary knob 87 is selected according to the size of the space where the plasma power supply protection device is placed. Then, the rotary knob 87 drives the threaded rod 82 to rotate. After that, the threaded rod 82 controls the threaded sleeve 83 to move through the thread. Then, the threaded sleeve 83 drives the connecting ears 84 on both sides to move. Then, the connecting ears 84 drive the fixed shafts 86 on both sides to move relative to each other through the first rotating plate 85. After that, the fixed shafts 86 drive the receiving plate 7 to move relative to each other, thereby controlling the size of the receiving plate 7 extending out of the lower base plate 1, and thus controlling the size of the space occupied by the plasma power supply protection device.

[0030] like Figure 2 and Figure 3As shown, the buffer assembly 11 includes a buffer chamber 1101, a buffer block 1102, a buffer spring 1103, a limiting groove 1104, and a limiting strip 1105; the buffer chambers 1101 are fixedly connected to the receiving plates 7, the buffer blocks 1102 are slidably connected to the inner walls of the buffer chambers 1101, and the buffer springs 1103 are fixedly arranged between the buffer blocks 1102 and the inner walls of the buffer chambers 1101 near the threaded rod 82. The upper end of the buffer blocks 1102 is rotatably connected to the third rotating plate 10.

[0031] Furthermore, a limiting groove 1104 is provided on the inner wall of the buffer chamber 1101, and limiting strips 1105 are fixedly connected to both sides of the buffer block 1102, and the limiting strips 1105 are slidably connected to the limiting grooves 1104.

[0032] Specifically, when the baffle 4 is hit, the baffle 4 pushes the second rotating plate 9 to rotate, then the second rotating plate 9 pushes the third rotating plate 10 to move, and then the third rotating plate 10 pushes the buffer block 1102 to slide on the inner wall of the buffer chamber 1101. The buffer block 1102 compresses the buffer spring 1103, and the buffer spring 1103 applies a reverse thrust to the buffer block 1102 in sync, which gradually increases as the buffer block 1102 slides.

[0033] The working principle of this utility model is as follows: the baffle 4 is collided with, and then the baffle 4 pushes the second rotating plate 9 to rotate. Then the second rotating plate 9 pushes the third rotating plate 10 to move. Then the third rotating plate 10 pushes the buffer block 1102 to slide on the inner wall of the buffer chamber 1101. The buffer block 1102 compresses the buffer spring 1103. The buffer spring 1103 applies a reverse thrust to the buffer block 1102, and the thrust gradually increases as the buffer block 1102 slides. When the space for placing the plasma power supply protection device is limited, the knob 87 is rotated, and then the knob 87 drives the threaded rod 82 to rotate. Then the threaded rod 82 controls the threaded sleeve 83 to move through the thread. Then the threaded sleeve 83 drives the connecting ears 84 on both sides to move. Then the connecting ears 84 drive the fixed shafts 86 on both sides to move relative to each other through the first rotating plate 85. Then the fixed shafts 86 drive the receiving plate 7 to move relative to each other, thereby controlling the size of the receiving plate 7 extending out of the lower base plate 1, so as to flexibly adjust the space occupied by the plasma power supply protection device.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
