Description

Technical Field

[0001] This utility model relates to a power surge protection control device, and in particular to a power surge protection control device for a Hall thruster test chamber, belonging to the technical field of power protection devices. Background Technology

[0002] The Hall thruster test chamber power surge protection control device is a device used to protect the power system inside the Hall thruster test chamber from surge voltage and current. The working principle of this device is mainly based on the basic principle of surge protectors, that is, by responding quickly to voltage changes, the excessive surge current is directed to the ground wire or other low impedance paths, thereby protecting the equipment in the circuit. When a transient overvoltage occurs in the power system of the test chamber, the sensitive components inside the protection control device, such as gas discharge tubes, metal oxide varistors, transient voltage suppression diodes, etc., will respond in a very short time, switch to a low impedance state, form a discharge channel, and conduct the surge current to the ground, while "clamping" the voltage at both ends of the equipment within a safe range.

[0003] The Hall thruster test chamber power surge protection control device mainly consists of four core modules: detection, graded protection, control, and stable adaptation. These four core modules are all installed inside the device's outer casing, which is then assembled onto the Hall thruster test chamber. To ensure the accuracy and smooth conduct of each test, the core modules need to be inspected before and after the test, or replaced with modules of corresponding parameters as needed. However, currently, modules are generally installed inside the casing using bolts, resulting in a significant time consumption for each module inspection. Furthermore, the contact area between the module and the casing contains numerous electronic components and circuits, requiring personnel to operate within the densely packed gaps between modules inside the casing. When repairing or replacing a single module, accidental contact by personnel or tools is likely, potentially affecting the normal operation of adjacent modules and significantly increasing the difficulty of module repair and replacement.

[0004] Therefore, it is urgent to improve the power surge protection control device of the Hall thruster test chamber to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a power surge protection control device for the Hall thruster test chamber, which solves the problem of inconvenient module replacement in existing technologies.

[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] like Figures 1-6 As shown, the Hall thruster test chamber power surge protection control device provided in this embodiment includes several through-hole mounting shells 1. Each mounting shell 1 has mounting holes 3 and an internal module body 2. Bolts are passed through the mounting holes 3 to mount the mounting shell 1 onto a bracket 25 inside the power protection device. The module body 2, located inside the mounting shell 1, is then mounted on the bracket 25 inside the shell. The module body 2 refers to the core module of the Hall thruster test chamber power surge protection control device. The device also includes a mounting bracket 4, a fastener 6, a locking assembly, and a drive assembly 7.

[0025] Specifically, the mounting bracket 4 is located inside the mounting housing 1 and slides along the through-line direction at the end of the mounting housing 1 via the guide rail 5; the fastener 6 is located at the bottom of the module body 2 and is adapted to be installed on the mounting bracket 4, protecting the module through the mounting housing 1, thereby isolating two adjacent independent module bodies 2 and preventing mutual interference; the locking component is located on the mounting bracket 4 and configured to lock the module body 2 onto the mounting bracket 4 via the fastener 6, and the locking component releases the locking state of the fastener 6 through a release structure; the drive component 7 is located on the mounting bracket 4 and is used to drive the mounting bracket 4 to slide. To facilitate the driving of the drive component 7, the device also includes a control system and a control switch, so that workers can easily start and stop the operation of the drive component 7. During use... Mounting bracket 4 is installed onto the inner bracket 25 of the housing. When maintenance or disassembly of one of the module bodies 2 is required, simply activate the drive component 7 on the corresponding mounting housing 1, which will drive the mounting bracket 4 to move away from the inner bracket 25 of the housing until it reaches the end position of the mounting housing 1. At this time, under the action of the release structure, the locking component is released from the lock of the buckle 6. After the buckle 6 is unrestrained, the worker can remove the module body 2 from the mounting bracket 4. When installing the module body 2, simply connect the buckle 6 to the mounting bracket 4, then activate the drive component and drive the mounting bracket 4 to the position of the inner bracket 25 of the housing. During the movement, the locking component relocks the buckle 6, and the module body 2 is locked on the mounting bracket 4 and is in a fixed state.

[0026] Among them, such as Figure 1 as well as Figure 5As shown, guide rails 5 are installed at the four corners of the mounting housing 1. The guide rails 5 extend along the through direction of the end of the mounting housing 1. The length of the guide rails 5 can be selected according to actual usage requirements and is not limited. The mounting bracket 4 has a sliding groove 9 through it, which is suitable for sliding on the guide rail 5. The mounting bracket 4 also has a mounting groove 8 through it, which is suitable for the fastener 6 to pass through. At this time, after moving the mounting bracket 4, the mounting bracket 4 can move on the guide rail 5. The mounting bracket 4 is designed with a hollow structure to facilitate the wiring connection on the module body 2.

[0027] At least one snap fastener 6 is provided. When multiple snap fasteners 6 are provided, the stability of the connection between the module body 2 and the mounting can be increased. When only one snap fastener 6 is provided, the structural cost can be reduced. One end of the snap fastener 6 extends outward from the bottom of the module body 2, and a trapezoidal snap fastening groove 10 is provided on the side wall at its end. When the module body 2 is installed on the mounting bracket 4, the end of the snap fastener 6 with the snap fastening groove 10 passes through the mounting groove 8 and extends to the other side of the mounting bracket 4.

[0028] To facilitate locking of the buckle 6, therefore, as Figure 6 As shown, the locking assembly described above includes a connecting rod 11, a locking block 12 connected to the end of the connecting rod 11, a sliding rod 13 connected to the connecting rod 11, and a guide rod 14 connected to the mounting bracket 4. The sliding rod 13 is provided with a sliding block 15, which is slidably connected to the guide rod 14. When one end of the buckle 6 with the buckle groove 10 passes through the mounting groove 8 and extends to the other side of the mounting bracket 4, the connecting rod 11 is moved. The connecting rod 11 slides along the extension direction of the guide rod 14, causing the locking block 12 to move toward the buckle groove 10. The locking block 12 has the same structure as the buckle groove 10, and the locking block 12 is suitable for movably engaging with the buckle groove 10. The trapezoidal structure makes it easier for the locking block 12 to engage with the buckle groove 10.

[0029] Furthermore, such as Figure 2 , Figure 3 , Figure 4 as well as Figure 6As shown, the release structure is a groove 18 formed on the side wall of the mounting housing 1, and the groove 18 is recessed towards the outside of the mounting housing 1. In order for the release structure to drive the locking assembly to release the locking state of the latch 6, the locking assembly mentioned above also includes a trapezoidal pressing block 16 connected to the connecting rod 11 and a telescopic spring 17 sleeved on the outside of the guide rod 14. The two ends of the telescopic spring 17 are respectively connected to the mounting bracket 4 and the sliding block 15. The groove 18 is suitable for accommodating the pressing block 16 and has the same shape as the pressing block 16, both being trapezoidal. When the pressing block 16 is located in the groove 18, the pressing block 16 will slide away from the telescopic spring 17 under the elastic force of the telescopic spring 17, and then through the connecting rod 11 moves the locking block 12 away from the latch groove 10, so that the two are no longer in a locked state. At this time, the module body 2 can be moved to detach the module body 2 and the latch 6 from the mounting bracket 4, completing the disassembly of the module body 2. When the mounting bracket 4 moves away from the groove 18, the pressing block 16 disengages from the groove 18 and moves towards the direction of the telescopic spring 17. While the telescopic spring 17 accumulates elastic force, it also pushes the pressing block 16 in the opposite direction, increasing the friction between the pressing block 16 and the inner wall of the mounting housing 1. When the pressing block 16 moves, it will drive the locking block 12 to engage in the latch groove 10 through the connecting rod 11, forming a locked state for the latch 6, so that the module body 2 is in a fixed state.

[0030] Furthermore, such as Figure 1 as well as Figure 5 As shown, the drive assembly 7 includes a drive member 19, a rack 20 connected to the drive member 19, gears 21 meshing with the rack 20, and a drive motor 22. The mounting housing 1 has an elongated groove 24, one end of which is connected to the outside. A protective shell 23 is connected to the outside of the elongated groove 24. The drive member 19 is slidably connected within the elongated groove 24. The gears 21 are all located within the protective shell 23. The drive motor 22 is mounted on the protective shell 23, and its output end is connected to the gears 21. The drive motor 22 is connected to the control system. Inter-coupling allows the worker to control the operation of the drive motor 22 via a switch. When the worker starts the drive motor 22, the drive motor 22 outputs torque, which in turn drives the gear 21 connected to its output end to rotate, which in turn drives the rack 20 meshing with the gear 21 to move, which in turn drives the drive component 19 connected to the rack 20 to move. The drive component 19 can then drive the mounting bracket 4 to move. As the output torque of the drive motor 22 changes direction, the mounting bracket 4 and the module body 2 can then reciprocate within the mounting housing 1. This operation can be completed through the operation control system.

[0031] The above-described structure secures and locks the module body 2, as well as releases constraints. Compared to using bolts to fix and install the module body 2, this method is more convenient and saves a lot of time. At the same time, when inspecting the module body 2, it can extend out from the mounting shell 1, which makes it easier for workers to inspect the module body 2. In addition, this method can offset the module body 2 from the surrounding modules, avoiding accidental contact by personnel or tools, thereby avoiding affecting the working status of adjacent modules and greatly reducing the difficulty of module maintenance and replacement operations.
