Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a pluggable heat dissipation housing for a high-speed sampling module for partial discharge signals. Background Technology

[0002] Partial discharge is a microscopic breakdown phenomenon caused by electric field concentration in the insulation system of power equipment. It is regarded as an early warning signal for potential equipment failures. With the accelerated development of smart grids and the integration of new energy sources, higher requirements are placed on the accuracy, real-time performance and reliability of PD detection technology. As a core component, the high-speed sampling module undertakes the key task of converting weak discharge pulses into analyzable digital signals. The performance indicators of the device, including sampling rate, resolution, signal-to-noise ratio and channel synchronization accuracy, constitute the performance boundary of the entire monitoring system and directly affect the accuracy and timeliness of condition-based maintenance decisions.

[0003] In existing technologies, traditional sampling modules typically use multiple bolts to fix the heat sink housing. However, bolt fixing tools are highly dependent on bolts, and the operation is time-consuming. A heat sink housing usually requires multiple bolts for fixing, which reduces the maintenance efficiency when disassembling the heat sink housing. At the same time, it is difficult to operate with bolts in narrow spaces. The bolt heads are easily blocked by adjacent equipment, and they are prone to slipping when manually tightened. They may even accidentally touch the electrical interfaces of surrounding modules, causing secondary faults. During emergency maintenance during peak power grid periods, this method may cause partial discharge signals to be missed due to operation delays, affecting the timeliness of equipment fault prediction.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a pluggable heat dissipation housing for a high-speed sampling module for partial discharge signals, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a pluggable heat dissipation housing for a high-speed sampling module for partial discharge signals. The housing includes a sampling device body, a heat dissipation shell body slidably connected to the top of the sampling device body, and connecting components abutting to both sides of the bottom of the heat dissipation shell body. The connecting components include a fixing plate installed on the inner wall of the sampling device body, a sliding block slidably connected to the inner wall of the fixing plate, a first guide groove formed on one side of the outer wall of the sliding block, a sliding column slidably connected to the inner wall of the first guide groove, a swing rod installed at the end of the sliding column away from the sliding block, an abutting column fixedly connected to the middle of the top of the sliding block, a spring fixedly connected to the middle of the bottom of the sliding block, two traction plates fixedly connected to the side of the sliding block away from the sliding column, each traction plate having a second guide groove formed on the side away from the sliding block, and a limit support plate slidably connected to the adjacent side of the two traction plates through the second guide groove. Connecting rods are rotatably connected to both sides of the limit support plate, and each connecting rod is fixedly connected to one side of the fixing plate.

[0007] Furthermore, a movable heat sink is slidably connected to the top of the heat sink body, a movable block is fixedly connected to one side of the outer wall of the movable heat sink, a threaded rod is threadedly connected to the inner wall of the movable block, and a fixed heat sink is fixedly connected to the inner wall of the heat sink body near the top.

[0008] Furthermore, sliding grooves are installed on both sides of the sampling device body, and the heat dissipation shell body is slidably connected to the sampling device body through the sliding grooves.

[0009] Furthermore, a dustproof net is laid on the inner wall of the heat dissipation shell body on the side close to the fixed heat dissipation plate. After the movable heat dissipation plate moves a suitable distance, the movable heat dissipation plate is aligned with the fixed heat dissipation plate.

[0010] Furthermore, a control panel is installed on one outer wall of the sampling device body, and the surface of the control panel is equipped with multiple control buttons and a display screen.

[0011] Furthermore, one end of the spring is fixedly connected to the middle of the bottom end of the sliding block, and the other end of the spring is fixedly connected to the middle of the inner bottom wall of the fixed plate. Both sides of the bottom end of the heat dissipation shell body are equipped with protrusions, and each protrusion is in contact with the abutting post and the limiting support plate in each connecting component.

[0012] Furthermore, the fixing plate is fixedly connected to the inner wall of the sampling device body, and an abutment block is installed at the top of the abutment column. The abutment block is made of anti-slip material, and the outer wall of the abutment column is slidably connected to the inner wall of the fixing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By using the sliding block of the connecting component in conjunction with the spring and the limit support plate, locking and unlocking can be completed by manually pressing and sliding, eliminating the tedious steps of tightening each bolt one by one. A single disassembly and assembly can directly complete the module fixing and separation, simplifying the operation process and shortening maintenance time.

[0015] 2. By using a sliding groove in conjunction with the connecting components, alignment and insertion result in direct locking, reducing monitoring interruption time.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5This utility model provides a technical solution: a pluggable heat dissipation housing for a high-speed partial discharge signal sampling module, including a sampling device body 1. A heat dissipation housing body 2 is slidably connected to the top of the sampling device body 1, enabling pluggable installation of the heat dissipation housing body 2 and providing a structural basis for rapid module maintenance. Connecting components are abuttingly connected to both sides of the bottom end of the heat dissipation housing body 2. The connecting components include a fixing plate 3 installed on the inner wall of the sampling device body 1, a sliding block 4 slidably connected to the inner wall of the fixing plate 3, a first guide groove 5 on one outer wall of the sliding block 4, and a sliding column 6 slidably connected to the inner wall of the first guide groove 5. A swing rod 7 is installed at the end of the sliding column 6 away from the sliding block 4. The sliding connection between the fixing plate 3 and the sliding block 4 limits the movement direction of the sliding block 4 to the vertical direction, ensuring the stability of the linkage of the connecting components. The sliding column 6, by sliding in the first guide groove 5, can drive the swing rod 7 to swing. The sliding column 6 limits the movement distance of the sliding block 4. An abutting column is fixedly connected to the middle of the top of the sliding block 4. 8. The contact post 8 transmits the contact pressure of the heat dissipation shell 2 to the sliding block 4, triggering the linkage of the connecting components. The contact post 8 can be directly subjected to force, ensuring that the locking and unlocking actions can be triggered by simple pressing. A spring 17 is fixedly connected to the middle of the bottom end of the sliding block 4. The spring 17 provides the reset force for the sliding block 4. After pressing, the movement distance of the sliding block 4 limited by the sliding post 6 is changed, thereby achieving different reset effects. Two traction plates 9 are fixedly connected to the side of the sliding block 4 away from the sliding post 6. Each traction plate 9 has a second guide groove 10 on the side away from the sliding block 4. The adjacent side of the two traction plates 9 is slidably connected to the limit support plate 11 through the second guide groove 10. The two sides of the limit support plate 11 are rotatably connected to the connecting rod 12. Each connecting rod 12 is fixedly connected to one side of the fixed plate 3. The traction plate 9 and the second guide groove 10 convert the vertical movement of the sliding block 4 into the rotational movement of the limit support plate 11. The locking and unlocking of the heat dissipation shell 2 is achieved through the rotation of the limit support plate 11.

[0024] See Figure 5 A movable heat sink 13 is slidably connected to the top of the heat sink body 2. A movable block 14 is fixedly connected to one outer wall of the movable heat sink 13. A threaded rod 15 is threadedly connected to the inner wall of the movable block 14. The movable block 14 converts the rotational motion of the threaded rod 15 into horizontal linear motion. At the same time, the movable block 14 directly transmits its own motion to the movable heat sink 13, thereby realizing the position adjustment of the movable heat sink 13. The fixed connection ensures that the movement of the movable heat sink 13 is consistent with that of the movable block 14. A fixed heat sink 16 is fixedly connected to the inner wall of the heat sink body 2 near the top. The fixed heat sink 16 is the basic heat dissipation unit. It works with the movable heat sink 13 to form a variable heat dissipation area, directly conducting the heat inside the shell to the outside.

[0025] See Figure 1The sampling device body 1 has sliding grooves installed on both sides. The heat dissipation shell body 2 is slidably connected to the sampling device body 1 through the sliding grooves. The sliding grooves provide a clear sliding trajectory for the heat dissipation shell body 2, ensuring that it docks with the sampling device body 1 in a preset direction. This avoids problems such as edge scratches and internal component collisions caused by positioning deviations during insertion and removal, thus protecting the integrity of the module structure. Compared with unguided direct insertion and removal, it can disperse friction and reduce jamming, making the insertion and removal of the heat dissipation shell body 2 smoother and reducing the operational intensity of maintenance personnel. The stability of the sliding process can reduce the instantaneous impact force when the heat dissipation shell body 2 docks with the sampling device body 1, preventing damage to internal precision components due to violent collisions and extending the service life of the module.

[0026] See Figure 5 The heat dissipation housing 2 has a dustproof net on the inner wall of the side near the fixed heat dissipation plate 16. The dustproof net blocks dust without excessively blocking the heat dissipation airflow, ensuring that the heat of the fixed heat dissipation plate 16 can be effectively conducted to the outside through airflow. When the movable heat dissipation plate 13 moves a suitable distance, it is aligned with the fixed heat dissipation plate 16. When aligned, the maximum heat dissipation area can be formed to meet the heat dissipation requirements of the module in high power consumption and high temperature scenarios. This allows the airflow to flow more smoothly through the entire heat dissipation area, reducing wind resistance and improving the efficiency of forced air cooling or natural heat dissipation. When the movable heat dissipation plate 13 is misaligned, it is directly shut off to completely prevent dust from entering.

[0027] See Figure 3 The fixing plate 3 is fixedly connected to the inner wall of the sampling device body 1. The top of the abutment column 8 is equipped with an abutment block. The abutment block is made of anti-slip material. The anti-slip material abutment block can increase the friction with the bottom of the heat dissipation shell body 2, avoid slippage when pressing or locking, and ensure that the abutment force of the shell can be accurately transmitted to the sliding block 4, stably triggering the linkage action of the subsequent traction plate 9 and limit support plate 11, reducing the risk of locking failure due to slippage. The outer wall of the abutment column 8 is slidably connected to the inner wall of the fixing plate 3.

[0028] See Figure 2 Both sides of the bottom of the heat dissipation housing body 2 are equipped with protrusions. Each protrusion is in contact with the abutment post 8 and the limiting support plate 11 in each connecting component. The protrusion directly abuts with the abutment post 8, which can concentrate the insertion and extraction force of the heat dissipation housing body 2 to the abutment post 8, thereby improving the stability of the structural response. The abutment connection between the protrusion and the limiting support plate 11 provides a clear force fulcrum for locking. The limiting support plate 11 can form a tight abutment relationship with the protrusion by rotation. Compared with planar contact, it can more effectively offset the lateral or longitudinal loosening force of the housing and reduce the risk of relative displacement between the housing and the sampling device body 1.

[0029] Working principle: When installing and locking, the heat dissipation shell body 2 is horizontally inserted along the sliding grooves on both sides of the sampling device body 1. The protrusion abuts against the anti-slip abutment block at the top of the abutment post 8, pushing the sliding block 4 to move vertically down along the fixed plate 3 and compressing the spring 17. One side of the sliding block 4 drives the sliding post 6 and the swing rod 7 to swing and limit the movement through the first guide groove 5. The other side of the traction plate 9 drives the limit support plate 11 to rotate around the connecting rod 12 through the second guide groove 10, and abuts against the protrusion to achieve locking. When unlocking, press the heat dissipation shell body 2 again to pull it out.

[0030] During heat dissipation adjustment, rotating the threaded rod 15 causes the moving block 14 to drive the moving heat sink 13 to slide along the top of the heat dissipation shell body 2. When aligned with the fixed heat sink 16 on the inner wall, it forms the maximum heat dissipation area and improves efficiency. When misaligned, it reduces the opening. At the same time, the dustproof net near the fixed heat sink 16 can block dust, taking into account both heat dissipation and protection.

[0031] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
