Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and in particular to an installation device for an environmental monitoring sensor for rail transit transformers. Background Technology

[0002] Sensors in rail transit transformers enable comprehensive control over transformer operation by real-time monitoring of the transformer's operating environment and its own condition. Temperature sensors monitor the temperature of critical components such as transformer windings and oil, preventing insulation aging or even fires caused by excessive heat. Humidity sensors monitor the humidity inside and around the transformer, preventing insulation performance degradation due to excessive humidity. This ensures the stable and safe operation of rail transit transformers and provides a solid guarantee for the reliable power supply of the rail transit system.

[0003] The installation device for environmental monitoring sensors on rail transit transformers includes a fixing plate, nuts, and other structures. The transformer tank wall end face and the fixing plate end face have matching lower and upper positioning screw holes. By installing a positioning threaded rod in the screw holes and a movable threaded block that inserts into the lower end of the positioning threaded rod, a stable connection between the mounting frame and the transformer tank wall can be achieved, completing the installation and enabling comprehensive and reliable monitoring of the operating environment of the rail transit transformer.

[0004] However, some existing rail transit transformer environmental monitoring sensor installation devices suffer from inconvenient connection issues during use. Some installation devices have complex fixing structures, employing multiple bolt fastening methods, which are inconvenient for maintenance personnel to operate within the narrow space of the transformer enclosure. Installation requires repeated calibration of the bolt hole positions, consuming significant time and effort. Furthermore, installation errors can easily lead to sensor loosening. When sensor replacement or repair is needed, disassembling and reconnecting the wiring is cumbersome, reducing work efficiency and causing signal transmission failures due to improper wiring connections. This, in turn, affects the real-time and accurate monitoring of the transformer's operating environment, increasing potential safety risks to the equipment. Therefore, this paper proposes a rail transit transformer environmental monitoring sensor installation device to solve these problems. Utility Model Content

[0028] 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.

[0029] An installation device for environmental monitoring sensors of rail transit transformers, referring to Figures 1 to 3The device includes a housing 1, with a fixing plate 2 fixedly connected to its bottom. The fixing plate 2 acts as a connecting element, enhancing the stability and integrity of the entire structure and allowing for the orderly installation and coordinated operation of all components. A connecting mechanism 3 is also fixedly connected to the bottom of the fixing plate 2, primarily responsible for connecting the device to external equipment such as sensors and transformers. A protective mechanism 4 is fixedly connected to the top of the fixing plate 2; this mechanism protects internal precision components such as sensors from damage caused by dust, debris, or external impacts. The connecting mechanism 3 includes a fixing disc 31, which has a large contact area, dispersing stress generated during connection and ensuring connection stability.

[0030] Specifically, the housing 1 is connected to the connecting mechanism 3 and the protective mechanism 4 via the fixing plate 2. The fixing plate 2 enhances the overall stability, the fixing plate 31 of the connecting mechanism 3 ensures stable connection with external equipment due to its large contact area, and the protective mechanism 4 provides protection against dust and impact for internal components such as sensors.

[0031] The top of the fixed plate 31 is fixedly connected to the bottom of the fixed plate 2. This fixed connection ensures that the fixed plate 31 is securely mounted on the fixed plate 2, providing reliable support for the installation of subsequent components. A connecting post 32 is fixedly connected to the bottom of the fixed plate 31. The connecting post 32 is vertically fixed to the bottom of the fixed plate 31, serving to transmit force and provide positioning. A limiting ball 2 is fixedly connected to the bottom of the connecting post 32. The limiting ball 2 is installed at the bottom of the connecting post 32, and its spherical structure design allows for flexible connection and limiting functions in conjunction with other components. Two limiting plates 33 are fixedly connected externally to the limiting ball 2. The two limiting plates 33 are symmetrically fixed to the outside of the limiting ball 2, achieving limiting and fixing of the limiting ball 2. A limiting ball 34 is fixedly connected to the bottom of the two limiting plates 33 on the adjacent side. The limiting ball 34 cooperates with the limiting ball 2, further enhancing the connection stability and flexibility of the connecting mechanism 3.

[0032] Specifically, the top of the fixed plate 31 is securely connected to the fixed plate 2 to provide support, and the bottom is connected to the limiting ball 2 through the connecting column 32. The limiting ball 2 is symmetrically fixed with two limiting plates 33. The bottom of the limiting plate 33 is connected to the limiting ball 34. The limiting ball 34 and the limiting ball 2 cooperate to achieve flexible connection and stable limiting of the connecting mechanism 3.

[0033] The limiting ball 34 is externally fixedly connected to a connecting post 35. Connecting post 35 maintains stability during connection, ensuring smooth force transmission between components of the connecting mechanism 3 and improving connection reliability. A fixing plate 36 is fixedly connected to the left side of connecting post 35. The structural design of fixing plate 36 effectively disperses stress generated during connection, ensuring connection stability. A connecting post 37 is fixedly connected to the left side of fixing plate 36. Connecting post 37 is fixedly connected to fixing plate 36 and its main function is to connect fixing plate 36 to external equipment such as transformers. Adjusting nuts 38 are threadedly connected to the inner walls of the two limiting plates 33. By rotating the adjusting nuts 38, the constraint force of the limiting plates 33 on the limiting balls 34 and 34 can be changed. A fixing assembly 39 is fixedly connected to the top of the fixing plate 2. The fixing assembly 39 includes two fixing chambers 391. The fixing chambers 391 ensure stable sliding and rotation of components within the chambers and also protect internal components.

[0034] Specifically, the first limiting ball 34 is connected to the second connecting column 35, the second fixing plate 36 and the third connecting column 37 in sequence to achieve a stable connection with external equipment. The adjusting nut 38 cooperates with the limiting plate 33 to adjust the constraint force on the limiting ball. The fixing component 39 on the fixing plate 2 ensures the stable operation and protection of internal components through the fixing chamber 391.

[0035] Two triangular limiting blocks 392 are slidably connected to the inner walls of each of the two fixed chambers 391. When the triangular limiting blocks 392 slide to a specific position, they can lock sensors and other components, achieving a fixing function. A pull rod 393 is slidably connected to the inner walls of each of the two fixed chambers 391. The pull rod 393 slides on the inner wall of the fixed chamber 391, and pulling the pull rod 393 controls the sliding of the triangular limiting blocks 392. A connecting rod 394 is rotatably connected to the inner wall of the top of each of the two pull rods 393. When the pull rod 393 is pulled, the connecting rod 394 can rotate around the connection point, converting the linear motion of the pull rod 393 into the sliding motion of the triangular limiting blocks 392. A movable shaft 395 is fixedly connected to adjacent sides of the multiple triangular limiting blocks 392, providing guidance and support for the sliding of the triangular limiting blocks 392 within the fixed chamber 391. Both fixed chambers 391 are slidably connected to the top of a release post 396. The release post 396 can slide vertically at the top of the fixed chamber 391 and is mainly used to control the fixed and released states of the triangular limit block 392.

[0036] Specifically, in the fixing component 39, the pull rod 393 slides in the fixing chamber 391, and the connecting rod 394 rotates to drive the triangular limit block 392 to slide along the moving axis 395, thereby fixing the sensor and other components; the release column 396 slides vertically at the top of the fixing chamber 391 to control the fixing and releasing states of the triangular limit block 392.

[0037] Two limiting strips 397 are rotatably connected to the inner walls of the bottom ends of the two release columns 396. When the release column 396 slides up and down, the limiting strips 397 can rotate around the connection point. The rotation of the limiting strips 397 can fix and release the triangular limiting block 392. Pressure balls 398 are fixedly connected to the inner walls of the two release columns 396. The design of the pressure balls 398 can ensure the stability and reliability of the rotation of the limiting strips 397, and can also drive the limiting strips 397 to reset. Control strips 399 are fixedly connected to the bottom ends of the two pull rods 393. The control strips 399 are fixed to the bottom ends of the pull rods 393, making it convenient for the operator to pull the pull rods 393 by hand. Restriction rings 302 are fixedly connected to the outer middle ends of the two release columns 396. The restriction rings 302 are used to limit the sliding range of the release column 396 and prevent the release column 396 from detaching from the fixed chamber 391 during the sliding process. Springs 301 are fitted around the top of each of the two release posts 396. The springs 301 serve to reset and buffer the movement of the release posts 396. A lower pressure plate 303 is fixedly connected to the top of each of the two release posts 396. The sensor is fixed by moving the housing 1 downward to push the lower pressure plate 303.

[0038] Specifically, when the release column 396 slides up and down, the limiting strip 397 at its bottom rotates around the connection point, which, together with the pressure ball 398, ensures stable rotation. The limiting ring 302 controls the sliding range, the top spring 301 acts as a reset buffer, the lower pressure plate 303 is pushed by the housing 1, and at the same time, the control strip 399 at the bottom of the pull rod 393 facilitates operation to control the fixing and release of the triangular limiting block 392.

[0039] Reference Figures 2 to 4 The protective mechanism 4 includes multiple retractable rods 41, the bottom ends of which are fixedly connected to the top of the fixed plate 2. The retractable rods 41 are securely anchored to the fixed plate 2, forming the bottom support foundation of the protective mechanism 4. Each of the retractable rods 41 has a threaded fixing nut 42 connected to its inner wall. When the retractable rod 41 is adjusted to the required length, rotating the fixing nut 42 can compress the inner wall of the retractable rod 41, causing slight deformation and clamping the internal nested components, thereby fixing the length of the retractable rod 41. Multiple rotating shafts 43 are rotatably connected to the inner wall of the top of the fixed plate 2. The rotating shafts 43 are installed in the pre-reserved mounting holes of the fixed plate 2 via bearings or bushings, forming a freely rotatable connection structure. Protective net rolls 44 are fixedly connected to the outside of each of the rotating shafts 43. When the rotating shafts 43 rotate, the protective net rolls 44 unfold or roll up accordingly, realizing the dynamic unfolding and retraction function of the protective net.

[0040] Specifically, the bottom end of the retractable rod 41 is fixed to the fixed plate 2 to form a protective bottom support, and the length is adjusted and locked by the fixing nut 42; the rotating shaft 43 is rotatably connected to the top of the fixed plate 2, driving the protective net roll 44 fixed thereon to achieve dynamic expansion or contraction.

[0041] Multiple protective net rolls 44 are fixedly connected to their top ends with multiple fixing blocks 46, and multiple retractable rods 41 are fixedly connected to their top ends with connecting frames 45. When the connecting frames 45 move upward, they drive the fixing blocks 46 to rise synchronously, thereby pulling the protective net rolls 44 to rotate and unfold along the rotating shaft 43; when they move downward, they push the protective net rolls 44 to roll up and store. The bottom ends of the multiple fixing blocks 46 are fixedly connected to the outside of the top ends of the multiple protective net rolls 44. During the unfolding of the protective net, the fixing blocks 46 bear the tension and distribute the force evenly to the protective net, avoiding excessive local stress that could cause damage; during the retraction process, the fixing blocks 46 help the protective net to tightly wrap around the rotating shaft 43, ensuring that the protective net rolls 44 are neatly stored and easy to use next time.

[0042] Specifically, the top of the protective net roll 44 is connected to the connecting frame 45 at the top of the retractable rod 41 via a fixing block 46. The connecting frame 45 moves up and down, driving the fixing block 46, which in turn pulls the protective net roll 44 to unfold or roll up along the rotating shaft 43. The fixing block 46 disperses the pulling force and assists in storage during the unfolding and retracting process.

[0043] Reference Figure 4 and Figure 6 Multiple triangular limiting blocks 392 are externally fixedly connected to the inner wall of the bottom end of the housing 1. The triangular limiting blocks 392 provide limiting and fixing points for components such as sensors. Utilizing the stability of the triangular structure, they effectively distribute force during the fixing process, preventing displacement or loosening of the sensors due to external forces. Multiple moving shafts 395 are externally slidably connected to the inner walls of the two fixed chambers 391. When the pull rod 393 pulls the connecting rod 394, it drives the triangular limiting blocks 392 to move, and the moving shafts 395 slide along the inner wall of the fixed chamber 391, thus guiding and supporting the triangular limiting blocks 392. Limiting slots are provided on the inner walls of the top edges of the multiple triangular limiting blocks 392 on adjacent sides. When the limiting strip 397 is engaged in the limiting slot, the triangular limiting blocks 392 are locked. The bottom ends of the multiple limiting strips 397 on opposite sides are fixedly connected to the top edges of the multiple triangular limiting blocks 392 on adjacent sides.

[0044] Specifically, the triangular limiting block 392 is fixed to the inner wall of the bottom end of the housing 1 to provide stable positioning for the sensor. The moving shaft 395 slides and guides within the fixed chamber 391. When the pull rod 393 pulls the connecting rod 394 to move the triangular limiting block 392, and the limiting strip 397 is engaged in the limiting slot of the triangular limiting block 392, the triangular limiting block 392 is locked.

[0045] When the release pin 396 returns to its upward position, the limiting strip 397 re-engages into the limiting slot, fixing the triangular limiting block 392. The two limiting rings 302 are externally slidably connected to the inner walls of the tops of the two fixed chambers 391. The limiting rings 302 and the inner walls of the tops of the fixed chambers 391 are in clearance fit, ensuring that the release pin 396 can slide up and down within the fixed chambers 391 while limiting its sliding range and preventing the release pin 396 from dislodging from the fixed chambers 391. The tops of the two springs 301 are fixedly connected to the bottoms of the two lower pressure plates 303. When the lower pressure plate 303 is pressed, the springs 301 are compressed, storing elastic potential energy; when the lower pressure plate 303 is released, the springs 301 release their elastic potential energy, pushing the lower pressure plate 303 and the release pin 396 upward to return to their original positions, causing the limiting strip 397 to re-engage into the limiting slot of the triangular limiting block 392. The two connecting rods 394 are rotatably connected to the two triangular limit blocks 392 on their adjacent sides. When the pull rod 393 is pulled, the pull rod 393 drives the connecting rod 394 to rotate around the connection point. The connecting rod 394 pushes the triangular limit block 392 to slide along the moving axis 395 in the fixed chamber 391.

[0046] Specifically, when the release post 396 returns to its upward position, the limit strip 397 re-engages into the limit slot to fix the triangular limit block 392, and the limiting ring 302 limits the sliding range of the release post 396. The spring 301 compresses and stores energy and pushes the return when the lower pressure plate 303 is pressed and released. Pulling the lever 393 drives the triangular limit block 392 to slide along the moving axis 395 through the connecting rod 394.

[0047] Two pressure plates 303 are externally fixedly connected to the inner wall of the bottom end of the housing 1. This fixed connection ensures that the operating force is effectively transmitted to the release post 396. The bottom ends of two pressure balls 398 are fixedly connected to the top of the adjacent sides of multiple limiting strips 397. When the release post 396 slides downwards, the pressure balls 398 move downwards along with it, utilizing the characteristics of their spherical structure to evenly transmit the pressure of the release post 396 to the limiting strips 397, pushing the limiting strips 397 to rotate around the connection point and disengage them from the limiting slot of the triangular limiting block 392. The external sides of the multiple limiting strips 397 are slidably connected to the inner walls of the two fixed chambers 391. When the release post 396 moves the limiting strips 397, the limiting strips 397 slide and rotate within the inner wall of the fixed chamber 391, completing the fixing and release of the triangular limiting block 392.

[0048] Specifically, the lower pressure plate 303 is fixed to the inner wall of the bottom end of the housing 1 to ensure that the operating force can be effectively transmitted to the release column 396. When the release column 396 slides down, the pressure ball 398 uses its spherical structure to evenly transmit the pressure to the limiting strip 397, pushing it to disengage from the limiting slot of the triangular limiting block 392. The limiting strip 397 slides and rotates on the inner wall of the fixed chamber 391 to achieve the fixing and release of the triangular limiting block 392.

[0049] The implementation principle of this application embodiment is as follows: When the adjusting nut 38 is loosened, the limiting plate 33 is driven to release the restriction on the limiting ball 34 and the limiting ball 2, so that the limiting ball 34 and the limiting ball 2 can move freely. This causes the fixing plate 31 to connect to the sensor through the connecting column 32, and the connecting column 37 to connect to the transformer through the fixing plate 36. At the same time, when the housing 1 moves down, it squeezes the lower pressure plate 303. When the lower pressure plate 303 moves, it pushes the release column 396. The release column 396 drives the limiting strip 397 to rotate, releasing the fixation on the triangular limiting block 392. The triangular limiting block 392 is then released and fixed to the housing 1 under the drive of the moving shaft 395 to achieve initial fixation.

[0050] When the sensor needs maintenance or replacement, the operator pulls the control bar 399. The control bar 399 drives the pull rod 393 to move on the inner wall of the fixed chamber 391. The pull rod 393 drives the triangular limit block 392 to move through the connecting rod 394, thereby releasing the fixation on the housing 1. This achieves the effect of stable connection and flexible disassembly and reliable fixation of the sensor and the equipment, effectively improving the convenience and stability of equipment installation and maintenance.

[0051] When the connecting frame 45 moves upward, the connecting frame 45 drives the fixing block 46 to move upward simultaneously. The fixing block 46 pulls the top of the protective net roll 44 upward, causing the protective net roll 44 to rotate and unfold around the pivot 43. During this process, the retraction rod 41 plays a supporting and guiding role. The length of the retraction rod 41 can be adjusted by tightening the fixing nut 42, thereby controlling the height of the connecting frame 45 and precisely adjusting the degree of unfolding of the protective net roll 44. When the protective net roll 44 is fully unfolded, the fixing nut 42 tightens the fixing retraction rod 41, keeping the protective net roll 44 stably in the protective state. This achieves a flexible and stable protection effect for the sensor, allowing the protection range to be adjusted according to actual needs and effectively resisting damage to the sensor from external factors.
