Technical Field
[0001] This utility model relates to the field of power equipment monitoring technology, and in particular to an adjustable installation device for an environmental monitoring sensor for rail transit transformers. Background Technology
[0002] Adjustable mounting devices are installation structures that can flexibly adjust their position, angle, and height, allowing for dynamic adjustments according to different needs. Rail transit transformers are core power devices in rail transit systems such as subways and light rails, converting external high-voltage electricity into low-voltage electricity required for train traction and station equipment. Environmental monitoring sensors can sense environmental factors such as temperature, humidity, and gas concentration, converting them into measurable signals such as electrical signals to provide data support for environmental monitoring. Adjustable mounting devices ensure that environmental monitoring sensors and transformers maintain the optimal monitoring distance and angle, avoiding monitoring deviations caused by rigid fixation, thereby improving the adaptability and reliability of the monitoring device.
[0003] The adjustable sensor mounting device mainly consists of a base assembly, an adjustment transmission structure, a sensor fixing mechanism, and locking and positioning components. During use, the base assembly serves as the mounting foundation, including a fixing plate connected to the equipment to ensure overall stability. The adjustment transmission structure enables multi-dimensional adjustments. The sensor fixing mechanism is mostly a clamping component that can be adapted to different sensor models, with built-in buffer pads to prevent sensor damage. Locking and positioning components, such as knobs, bolts, and buckles, are used to fix the device after adjustment to the target position, preventing vibration-induced displacement from affecting monitoring accuracy.
[0004] In existing technologies, the adjustable mounting devices for some sensors present complexities in adjustment operations. During installation or maintenance, it is necessary not only to disassemble multiple sets of fixing bolts and loosen cable joints, but also to repeatedly work in confined spaces using specialized tools such as wrenches. Even so, adjusting the basic position alone requires the collaboration of multiple people. More importantly, this process is prone to causing distortion of monitoring data due to positional deviations, which ultimately not only significantly extends the installation and commissioning cycle but also significantly increases maintenance costs. To address these issues, an adjustable mounting device for environmental monitoring sensors of rail transit transformers is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an adjustable installation device for environmental monitoring sensors of rail transit transformers. It aims to improve the problem that the adjustable installation devices of some sensors in the prior art are too complicated to operate during the adjustment process, which greatly prolongs the installation and commissioning cycle and significantly increases the maintenance cost.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An adjustable mounting device for an environmental monitoring sensor for a rail transit transformer includes a threaded knob. Two support plates are threadedly connected to the outer wall of the threaded knob. A rotating mechanism is mounted on the outside of the support plates, and an adjustment mechanism is mounted on the right side of the rotating mechanism.
[0008] The rotating mechanism includes a rotating rod 1, the outer wall of which is rotatably connected to the outer walls of the two support plates. A rotating ring 1 is fixedly connected to the right side of the rotating rod 1. A support ring is threadedly connected to the outer wall of the rotating ring 1. A rotating ring 2 is threadedly connected to the outer wall of the rotating ring 1. A connecting assembly is provided on the left side of the support plate.
[0009] Furthermore, the connecting assembly includes a second rotating rod, the right side of which is rotatably connected to the left side of the support plate, and a third rotating ring is fixedly connected to the left side of the second rotating rod, with a connecting barrel threaded onto the outer wall of the third rotating ring.
[0010] Furthermore, the adjustment mechanism includes a protective shell, the left side of which is fixedly connected to the right side of the rotating ring, a sliding shell slidably connected to the inner wall of the protective shell, a fixed ring rotatably connected to the inner wall of the protective shell, connecting arms fixedly connected to both the upper and lower sides of the fixed ring, a knob fixedly connected to the outer wall of the connecting arm, a sliding ring slidably connected to the inner wall of the fixed ring, a plurality of dampers fixedly connected to the right side of the sliding ring, a spring sleeved on the outside of the damper, and two sliding columns fixedly connected to the inner wall of the fixed ring.
[0011] Furthermore, the inner wall of the sliding ring has two sliding grooves, and the inner wall of the protective shell has two sliding grooves.
[0012] Moreover, the outer wall of the connecting arm is slidably connected to the outer wall of the second slide groove, and the outer wall of the sliding column is slidably connected to the outer wall of the first slide groove;
[0013] Moreover, the right side of each of the dampers is fixedly connected to the inner wall of the sliding shell, and the inner wall of the sliding shell is slidably connected to the outer wall of the rotating ring.
[0014] Moreover, one end of each of the multiple springs is fixedly connected to the right side of the sliding ring, and the other end of each of the multiple springs is fixedly connected to the inner wall of the sliding shell.
[0015] Furthermore, the left side of the support ring is in contact with the right side of the sliding shell, and the left side of the second rotating ring is in contact with the right side of the support ring.
[0016] This utility model has the following beneficial effects:
[0017] 1. In this utility model, the support plate is clamped and released by the threaded knob. After the constraint on the rotating rod is released, the rotating rod drives the rotating ring to rotate, thereby adjusting the angle between the support ring and the connecting component, so as to achieve precise adjustment and fixation of the sensor installation angle. Compared with the prior art, it eliminates the need for tool operation and multiple people to cooperate, reduces data distortion, shortens the debugging cycle and reduces maintenance costs, and improves installation and maintenance efficiency.
[0018] 2. In this utility model, the connecting arm slides in the groove by means of a knob, which drives the fixed ring to rotate, so that the sliding column pushes the sliding ring to move, thereby compressing or releasing the damper and the spring, realizing stepless adjustment of the buffer force. Compared with the prior art, the adjustment mechanism can dynamically adjust the damping according to the vibration environment, effectively absorb the continuous vibration in the operation of rail transit, ensure the stable operation of the sensor, and improve the reliability of environmental parameter monitoring data.

[0026] 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.
[0027] An adjustable mounting device for environmental monitoring sensors of rail transit transformers, as described above. Figure 1 and Figure 2 The device includes a threaded knob 1, with a threaded part at the bottom and a knob part at the top. Two support plates 2 are threadedly connected to the outer wall of the threaded knob 1. The threaded knob 1 is connected to the two support plates 2 through the outer wall thread, thus realizing the clamping and releasing operation. When the two support plates 2 are close to each other, the clamping operation is performed. When the two support plates 2 are far apart, the releasing operation is performed. A rotating mechanism 3 is installed on the outside of the support plate 2, and an adjusting mechanism 4 is installed on the right side of the rotating mechanism 3.
[0028] The rotating mechanism 3 includes a rotating rod 301, which is a component of the rotating mechanism 3. The outer wall of the rotating rod 301 is rotatably connected to the outer walls of the two support plates 2. The rotating rod 301 forms a rotatable connection structure with the outer walls of the two support plates 2 through its outer wall. The rotating rod 301 can rotate around the support plates 2, thereby realizing the angle adjustment of the rotating rod 301. A rotating ring 302 is fixedly connected to the right side of the rotating rod 301. The rotating ring 302 is fixed to the right side of the rotating rod 301. 2. Rotating synchronously with the rotating rod 301, the outer wall of the rotating ring 302 is threaded with a support ring 303. The support ring 303 is threaded to the outer wall of the rotating ring 302 and can be disassembled. The outer wall of the rotating ring 302 is threaded with a rotating ring 304. The rotating ring 304 is threaded to the outer wall of the rotating ring 302 and is used to fix the support ring 303. At the same time, the rotating ring 304 can be disassembled. A connecting component 305 is provided on the left side of the support plate 2.
[0029] The connecting assembly 305 includes a second rotating rod 3051, which is a component of the connecting assembly 305. The right side of the second rotating rod 3051 is rotatably connected to the left side of the support plate 2, and the right side of the second rotating rod 3051 is rotatably connected to the left side of the support plate 2. The second rotating rod 3051 can rotate around the support plate 2. A third rotating ring 3052 is fixedly connected to the left side of the second rotating rod 3051. The third rotating ring 3052 rotates together with the second rotating rod 3051. A connecting barrel 3053 is threadedly connected to the outer wall of the third rotating ring 3052. The connecting barrel 3053 is threadedly connected to the outer wall of the third rotating ring 3052 and is used to connect to the transformer cabinet.
[0030] Specifically, when the threaded knob 1 is turned upwards, the downward pressure exerted by the threaded knob 1 on the upper support plate 2 decreases, and the distance between the upper and lower support plates 2 gradually increases. The constraint force of the support plate 2 on the rotating rod 301 and the rotating rod 3051 is released, allowing the rotating rods 301 and 3051 to rotate on the outer wall of the support plate 2 to adjust their angle. At this time, the rotating rod 301 drives the rotating ring 302 fixed on the right side to rotate synchronously. The support ring 303 and the rotating ring 304 threadedly connected to the outer wall of the rotating ring 302 change position with the rotating ring 302, while the rotating ring 3052 fixed on the left side of the rotating rod 3051 also rotates with the rotating rod 3051. 051 rotates, and the connecting bucket 3053, which is threaded to the outer wall of the rotating ring 3052, adjusts the connection angle with the transformer cabinet. After the angle adjustment is completed, turn the threaded knob 1 downwards. The squeezing force on the upper support plate 2 increases, and the distance between the upper and lower support plates 2 decreases. The rotating rod 1 301 and the rotating rod 2 3051 are clamped again so that they cannot rotate. At this time, the rotating ring 1 302, the support ring 303, the rotating ring 2 304 and the connecting assembly 305 are all fixed. If the rotating ring 2 304 is turned to the right, the fixing of the support ring 303 can be released and it can be removed. If the connecting bucket 3053 is turned to the left, the entire installation device can be disassembled from the rotating ring 3052.
[0031] Reference Figures 3 to 5The adjusting mechanism 4 includes a protective shell 401, which is a component of the adjusting mechanism 4. The left side of the protective shell 401 is fixedly connected to the right side of the rotating ring 302. The left side of the protective shell 401 is fixedly connected to the right side of the rotating ring 302. The protective shell 401 moves with the rotating ring 302. A sliding shell 402 is slidably connected to the inner wall of the protective shell 401. The sliding shell 402 can move along the inner wall of the protective shell 401, and the protective shell 401 provides guidance for the sliding of the sliding shell 402. A fixed ring 403 is rotatably connected to the inner wall of 01. The protective shell 401 provides rotation space for the fixed ring 403. Connecting arms 404 are fixedly connected to both the upper and lower sides of the fixed ring 403. The connecting arms 404 are used to transmit force to the fixed ring 403. The connecting arms 404 can drive the fixed ring 403 to move. A knob 405 is fixedly connected to the outer wall of the connecting arm 404. The knob 405 is used to control the connecting arm 404. The force of the knob 405 is transmitted to the fixed ring 403 through the connecting arm 404.
[0032] A sliding ring 406 is slidably connected to the inner wall of the fixed ring 403. The sliding ring 406 can move along the inner wall of the fixed ring 403. When the sliding ring 406 moves to the right, the damping of the support ring 303 increases; when the sliding ring 406 moves to the left, the damping of the support ring 303 decreases. Multiple dampers 407 are fixedly connected to the right side of the sliding ring 406. The dampers 407 are fixed to the right side of the sliding ring 406 and adjust the damping as the sliding ring 406 moves. When the sliding ring 406 moves to the right, the dampers 407 are compressed to the right; when the sliding ring 406 moves to the left, the dampers 407 are stretched to the left. A spring 408 is sleeved on the outside of the damper 407. The spring 408 is sleeved on the outside of the damper 407 and works with the damper 407 to buffer. Two sliding posts 409 are fixedly connected to the inner wall of the fixed ring 403. The sliding posts 409 are fixed to the inner wall of the fixed ring 403 and are used to guide the movement of the sliding ring 406. Two sliding grooves 410 are opened on the inner wall of the sliding ring 406 and are used to cooperate with the sliding posts 409. Two sliding grooves 411 are opened on the inner wall of the protective shell 401 and are used to cooperate with the connecting arm 404.
[0033] Specifically, when the knob 405 on the upper side of the protective shell 401 is turned to the rear, the knob 405 causes the connecting arm 404 to slide backward along the second slide groove 411 on the inner wall of the protective shell 401. At the same time, when the lower knob 405 is turned to the left front, the corresponding connecting arm 404 slides forward along the second slide groove 411. The opposite movement of the upper and lower connecting arms 404 causes the fixing ring 403 to rotate clockwise. The sliding post 409 on the inner wall of the fixing ring 403 rotates with the fixing ring 403. The upper sliding post 409 slides backward along the first slide groove 410 on the inner wall of the sliding ring 406, and the lower sliding post 409 slides forward along the first slide groove 410, thereby pushing the sliding ring 406 to the left. When the sliding ring 406 moves to the right, the damper 407 on the right side of the sliding ring 406 is compressed, and the external spring 408 stores energy simultaneously. At this time, the sliding shell 402 is pushed to the right by the damper 407 to press against the support ring 303, which increases the damping between the support ring 303 and the rotating ring 302, thus enhancing the buffering effect. If the upper knob 405 is moved forward and the lower knob 405 is moved to the right rear, the connecting arm 404 drives the fixed ring 403 to rotate counterclockwise, the sliding column 409 slides in the opposite direction along the slide groove 410 and pulls the sliding ring 406 to the left, the damper 407 resets, the spring 408 releases its elastic potential energy, the damping of the support ring 303 decreases, and the buffering capacity weakens.
[0034] Reference Figure 4 and Figure 5 The outer wall of the connecting arm 404 is slidably connected to the outer wall of the second slide groove 411. The connecting arm 404 moves along the second slide groove 411, which provides guidance for the sliding of the connecting arm 404. The outer wall of the sliding column 409 is slidably connected to the outer wall of the first slide groove 410. The sliding column 409 moves along the first slide groove 410, which provides guidance for the sliding of the sliding column 409. The right side of the multiple dampers 407 is fixedly connected to the inner wall of the sliding shell 402. The dampers 407 are connected to the sliding shell 402, which transmits the energy from the support ring 303. The vibration is transmitted to the damper 407. The inner wall of the sliding shell 402 is slidably connected to the outer wall of the rotating ring 302. The right side of the screw of the rotating ring 302 has threads, while the left side of the screw of the rotating ring 302 does not have threads. The unthreaded part is used to provide a sliding base for the sliding shell 402. The sliding shell 402 can slide along the rotating ring 302. One end of each of the multiple springs 408 is fixedly connected to the right side of the sliding ring 406. One end of the spring 408 is fixed to the right side of the sliding ring 406. The spring 408 is compressed or stretched as the sliding ring 406 moves.
[0035] The other ends of multiple springs 408 are fixedly connected to the inner wall of the sliding shell 402. The sliding shell 402 transmits the vibration from the support ring 303 to the springs 408. The left side of the support ring 303 is in contact with the right side of the sliding shell 402, which is used to transmit the vibration to the sliding shell 402. The left side of the rotating ring 304 is in contact with the right side of the support ring 303. When the rotating ring 304 is in contact with the support ring 303, the rotating ring 304 is used to fix the support ring 303. When the rotating ring 304 is away from the support ring 303, the support ring 303 can be disassembled.
[0036] Specifically, when the buffering effect needs to be adjusted, the connecting arm 404 slides backward or forward along the second slide groove 411. The connecting arm 404 drives the fixed ring 403 to rotate, and the sliding column 409 slides in the first slide groove 410, pushing the sliding ring 406 to move to the right or left. When the sliding ring 406 moves, it compresses or releases the damper 407 and the spring 408: when moving to the right, the damper 407 is compressed, the spring 408 stores energy, and the sliding shell 402 is pushed to the right against the support ring 303 by the thrust. The vibration passes through the support ring. Vibration 303 is transmitted to the sliding shell 402, and then buffered by the damper 407 and the spring 408. When moving to the left, the damper 407 resets and the spring 408 releases potential energy, reducing the buffering capacity. When the support ring 303 is disassembled, the rotating ring 2 304 is turned to the right to separate it from the support ring 303. After the support ring 303 is no longer fixed, it can be removed from the rotating ring 1 302. At this time, the sliding shell 402 still slides along the outer wall of the rotating ring 1 302, maintaining the contact relationship with the support ring 303 is released, and the vibration transmission path is interrupted.
[0037] The implementation principle of this application embodiment is as follows: the connecting bucket 3053 is used to connect with the transformer cabinet, and the support ring 303 is used to connect the sensor. When the angle between the cabinet and the sensor needs to be adjusted, the operator turns the threaded knob 1 upward. For the support plate 2 located on the upper side, the downward pressing force of the threaded knob 1 will decrease, so that the distance between the upper support plate 2 and the lower support plate 2 gradually increases. At this time, the support plate 2 loses the constraint force on the rotating rod 1 301 and the rotating rod 2 3051. The rotating rod 1 301 and the rotating rod 2 3051 can then be angled on the outer wall of the two support plates 2. When the rotating rod 1 301 and the rotating rod 2 3051 are adjusted to the desired angle... After reaching the appropriate angle, the operator turns the threaded knob 1 downwards. The threaded knob 1 begins to move downwards, and the downward pressure on the upper support plate 2 increases accordingly. The distance between the upper support plate 2 and the lower support plate 2 decreases, and the constraint force of the support plate 2 on the rotating rod 301 and the rotating rod 3051 increases. At this time, the rotating rod 301 and the rotating rod 3051 can no longer rotate, thus completing the fixing operation of the rotating rod 301 and the rotating rod 3051, and finally achieving rapid angle adjustment. If the sensor needs to be disassembled, the operator turns the rotating ring 304 to the right to remove the support ring 303. If the entire installation device needs to be removed, the connecting bucket 3053 can be turned to the left.
[0038] When increased cushioning effect on the support ring 303 is required, the operator moves the knob 405 located on the upper side of the protective shell 401 backward. The knob 405 will cause the corresponding connecting arm 404 to move backward. For the knob 405 located on the lower side of the protective shell 401, the operator moves the knob 405 to the left front. The knob 405 will cause the corresponding connecting arm 404 to move forward. The two connecting arms 404 slide along their respective corresponding slide grooves 411, thereby causing the fixing ring 403 to rotate clockwise. As the fixing ring 403 rotates, it will also cause the two sliding posts 40 fixedly connected to its inner wall to rotate. The two sliding pins 409 rotate clockwise together. The sliding pin 409 located on the upper side of the sliding ring 406 slides backward along the corresponding groove 410. The sliding pin 409 located on the lower side of the sliding ring 406 slides forward along the corresponding groove 410. The sliding of the two sliding pins 409 will push the sliding ring 406 to the right. When the sliding ring 406 moves to the right, it will compress multiple springs 408. After the springs 408 are compressed, they store elastic force. At this time, the damping between the support ring 303 and the rotating ring 302 increases, and the buffering capacity of the support ring 303 is enhanced, thereby improving the stability of the sensor after installation.
[0039] When it is necessary to reduce the buffering effect on the support ring 303, the operator moves the knob 405 located on the upper side of the protective shell 401 forward and the knob 405 located on the lower side of the protective shell 401 to the right rear. The two knobs 405 respectively drive the corresponding connecting arms 404 to slide in the opposite direction along the second slide groove 411. The connecting arms 404 drive the fixed ring 403 to rotate counterclockwise. The fixed ring 403 drives the sliding column 409 to rotate in the opposite direction. The sliding column 409 slides in the opposite direction along the first slide groove 410 and pushes the sliding ring 406 to move to the left. The spring 408 gradually returns to its original position, and the damping between the support ring 303 and the first rotating ring 302 decreases. The buffering capacity of the support ring 303 is weakened accordingly. At this time, the sensor's accuracy in capturing vibration signals and its dynamic response capability are improved.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
