Description

Technical Field

[0001] This invention relates to the field of security detection cards, specifically a dual-channel TSI card that supports mixed measurement of multiple signal types. Background Technology

[0002] The turbine safety monitoring system (TSI) card in the power industry is generally a dual-channel card. TSI: turbine safety monitoring system, can accurately and reliably measure important parameters such as speed, displacement, vibration, and thermal expansion during the operation of the turbine. There are currently more than 50 TSI measurement points in large steam turbine units, with as many as 10 or more signal types. In order to ensure the safety of the steam turbine, each measurement point needs to be equipped with a detection card. The integrity of the unit's measurement points is checked regularly through the detection card. At present, if each TSI measurement point is equipped with a separate card, more than 50 cards are needed. In addition, at least one spare part is required for each type of card, resulting in high total cost. For users, this will increase the number of cards and spare parts, and increase daily maintenance costs. To address this, we have proposed a dual-channel TSI card that supports mixed measurement of multiple signal types. Summary of the Invention

[0003] The purpose of this invention is to provide a dual-channel TSI card that supports mixed measurement of multiple signal types, thereby reducing the number of cards required and saving daily maintenance costs, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A dual-channel TSI card supporting mixed measurement of multiple signal types includes a card housing. A mounting plate is fixedly installed at the center of the card housing. Signal detection motherboard one and signal detection motherboard two are bolted to the upper and lower ends of the mounting plate, respectively. Signal input and output ports are installed at both ends of both signal detection motherboard one and signal detection motherboard two. Adapters are movably installed at both ends of the mounting plate. One end of the adapter near the signal port has a signal output port, and the other end of the adapter has a signal input port. The signal port and the signal output port are movably fitted together. A silicone corrugated sleeve is fixedly installed between the outer surface of the signal input port and the card housing. A switching mechanism, installed outside the adapter, allows switching the insertion position of the signal input port. A toggle mechanism, installed inside the card housing, allows simultaneous activation of both external switching mechanisms. The adapters are existing connector converters.

[0005] Preferably, the switching mechanism includes a sleeve frame fixedly installed on both sides of the mounting plate. The sleeve frame covers the outside of the adapter. Cavities are formed on the front and rear end faces of the sleeve frame. Two guide sliders symmetrically distributed laterally are fixedly installed inside the cavities. Two isosceles triangular blocks symmetrically distributed vertically are also fixedly installed inside the cavities. The midpoint of the centerline between the two isosceles triangular blocks coincides with the midpoint of the centerline between the two guide sliders. The upper or lower end face of one of the isosceles triangular blocks is flush with the upper or lower end face of the guide slider. Three faces of the isosceles triangular block correspond to the shortest distance between the cavity and the inclined plane of the guide slider. A guide plate is hinged to the isosceles triangular block near the isosceles angle of the mounting plate via a pivot and a coil spring. The lower end face of the guide plate is flush with the isosceles triangular block. The right-side inclined surface is flush with the isosceles triangle block. At the isosceles angle of the isosceles triangle block away from the mounting plate, a guide plate is hinged to it via a pivot and a coil spring. The upper surface of the guide plate is flush with the upper surface of the isosceles triangle block. Both the guide plate and the guide plate slide into the guide slider and the sleeve frame. A blocking post is installed on the outer side of both the guide plate and the guide plate, and the blocking post is fixedly connected to the sleeve frame. A baffle is fixedly installed between the upper isosceles triangle block and the left guide slider. There are two baffles, which are equidistantly distributed in a circle with the center of the cavity as the center. The cavity also houses a tower bridge assembly and a limiting assembly. The guide plates can swing elastically under the action of the coil springs. The blocking posts limit the swing angle of the guide plates.

[0006] Preferably, the tower bridge assembly includes two arc-shaped sliders arranged in a circular array in the middle of the cavity, and the two arc-shaped sliders are respectively slidably positioned between the isosceles triangular block and the guide slider. The distribution positions of the two arc-shaped sliders are consistent with the distribution positions of the two baffles. A sliding block is fixedly installed at one end of the arc-shaped slider near the baffle, and a limiting groove is opened on the inner wall of the sleeve corresponding to the outside of the sliding block. A second spring is fixedly installed between the sliding block and the limiting groove. Under the action of the two second springs, the two arc-shaped sliders are spliced ​​together and can be just built on the front end of the baffle.

[0007] Preferably, the limiting component includes octagonal blocks fixedly installed at both ends of the adapter, and an octagonal slider is slidably installed at the end of the octagonal block away from the adapter via a sliding rod. A spring is fixedly installed between the octagonal block and the octagonal slider. The octagonal block and the octagonal slider are slidably embedded in the groove formed by the guide slider, the isosceles triangle block, and the cavity. A straight groove is opened on the side of the octagonal slider that is in contact with the sleeve frame. A straight bar is fixedly installed on the arc surface of the arc top slider, and the straight bar is slidably engaged with the straight groove. The two sides of the octagonal slider near the end of the straight groove are rounded. The rounded chamfer design is to ensure that the octagonal slider can smoothly slide onto the arc surface of the arc top slider during the movement. When the octagonal slider slides onto the arc surface of the arc top slider, its straight groove and straight bar are movably engaged, which can ensure the stability of the octagonal slider's sliding.

[0008] Preferably, a tensioning assembly is installed between the outer side of the sleeve frame and the adapter. The tensioning assembly includes a slide rail fixedly installed at both ends of the sleeve frame, and a spherical slider is slidably embedded inside the slide rail. A tension spring is fixedly installed between the front and rear ends of the adapter and the spherical slider through a retaining plate. The function of the tension spring is to always apply pressure to the adapter toward the inside of the retaining housing.

[0009] Preferably, the actuating mechanism includes two elliptical disks installed inside the card housing, with the two elliptical disks respectively positioned at the upper end of the first signal detection main board and the lower end of the second signal detection main board. A rotating shaft is fixedly installed inside the elliptical disk, and the rotating shaft rotatably passes through the card housing. A swing arm is fixedly sleeved on the outer surface of each of the two rotating shafts, and a fixing rod is fixedly installed between the two swing arms. A pushing component is installed outside the elliptical disk, which can simultaneously rotate the two swing arms via the fixing rod.

[0010] Preferably, the pushing assembly includes slide rods fixedly installed at the upper and lower ends of the adapter, connecting rods installed at both ends of the elliptical disk, and the connecting rods are slidably installed inside the clamping housing via brackets. A clamping block is fixedly installed at the end of the connecting rod near the elliptical disk, and the clamping block is slidably engaged with the outside of the elliptical disk. A semi-circular arc sleeve block is fixedly installed at the end of the connecting rod away from the elliptical disk, and the semi-circular arc sleeve block is slidably engaged with the slide rod. During the rotation of the elliptical disk, the two connecting rods can be pushed, so that the two adapters can be pushed simultaneously by the slide rods.

[0011] Preferably, the swing angle of the swing arm is less than 90 degrees. In order to ensure that after the elliptical disk effectively pushes the two adapters through the connecting rod, the elliptical disk and the swing arm can automatically reset under the action of the two tensioning components.

[0012] Preferably, the connecting rod is collinear with the transverse centerline of the clamp housing to ensure the stability of the connecting rod in pushing the adapter.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention uses a toggle mechanism to activate a switching mechanism, causing two adapters to repeatedly and synchronously switch between two signal ports on signal detection main board one and signal detection main board two. This enables a back-and-forth switching safety detection operation for two different TSI measurement points, reducing the number of detection cards required for large steam turbine units to about 30, thus lowering the total cost and significantly reducing costs while ensuring the safe operation of the steam turbine unit.

[0018] Please see Figure 6 and Figure 7The switching mechanism 10 shown in the figure includes a sleeve 23 fixedly installed on both sides of the mounting plate 2. The sleeve 23 is fitted over the adapter 6. The front and rear end faces of the sleeve 23 have cavities.

The upper or lower end face of one of the isosceles triangular blocks 28 is flush with the upper or lower end face of the guide slider 27. The three faces of the isosceles triangular block 28 are equal to the shortest distance between the cavity and the inclined surface of the guide slider 27. A guide plate 30 is hinged to the isosceles triangular block 28 near the isosceles angle of the mounting plate 2 via a pivot and a coil spring. The lower end face of the guide plate 30 is flush with the right inclined surface of the isosceles triangular block 28. A guide plate 31 is hinged to the isosceles triangle block 28 at the isosceles angle away from the mounting plate 2 via a pivot 2 and a coil spring 2. The upper end face of the guide plate 31 is flush with the upper end face of the isosceles triangle block 28.

The inside of the cavity is also equipped with a tower bridge assembly 14 and a limiting assembly 15. The guide plate 30 and the guide plate 31 can swing elastically under the action of the coil spring 1 and the coil spring 2. At the same time, the blocking posts are used to limit the swing angle of the guide plate 30 and the guide plate 31.

[0019] Please see Figure 9 The tower bridge assembly 14 shown in the figure includes two arc-shaped sliders 36 arranged in a circular array in the middle of the cavity. The two arc-shaped sliders 36 are slidably positioned between the isosceles triangle block 28 and the guide slider 27. The distribution positions of the two arc-shaped sliders 36 are consistent with the distribution positions of the two baffles 39. A sliding block is fixedly installed at one end of the arc-shaped slider 36 near the baffle 39. A limiting groove 35 is opened on the inner wall of the sleeve frame 23 corresponding to the outer side of the sliding block.

[0020] Please see Figure 8The limiting component 15 shown in the figure includes octagonal blocks 29 fixedly installed at both ends of the adapter 6. An octagonal slider 32 is slidably installed on the end of the octagonal block 29 away from the adapter 6 via a sliding rod. A spring 33 is fixedly installed between the octagonal block 29 and the octagonal slider 32. The octagonal block 29 and the octagonal slider 32 are slidably embedded in the groove formed by the guide slider 27, the isosceles triangular block 28, and the cavity. A straight groove 3 is provided on the side of the octagonal slider 32 that fits against the sleeve frame 23. 4. A straight bar 38 is fixedly installed on the arc surface of the arc top slider 36, and the straight bar 38 slides and engages with the straight groove 34. The two sides of the octagonal slider 32 near the end of the straight groove 34 are chamfered. The chamfer is designed to ensure that the octagonal slider 32 can slide smoothly onto the arc surface of the arc top slider 36 during its movement. When the octagonal slider 32 slides onto the arc surface of the arc top slider 36, the straight groove 34 and the straight bar 38 are engaged, which can ensure the stability of the sliding of the octagonal slider 32.

[0021] Please see Figure 4 In the figure, a tension assembly 13 is installed between the outside of the sleeve frame 23 and the adapter 6. The tension assembly 13 includes a slide rail 24 fixedly installed at the front and rear ends of the sleeve frame 23, and a spherical slider 25 is slidably embedded inside the slide rail 24. A tension spring 26 is fixedly installed between the front and rear ends of the adapter 6 and the spherical slider 25 through a clamping plate. The function of the tension spring 26 is to always apply pressure to the adapter 6 toward the inside of the clamping housing 1.

[0022] Please see Figure 3 The actuating mechanism 11 shown in the figure includes two elliptical disks 22 installed inside the card housing 1. The two elliptical disks 22 are respectively placed at the upper end of the signal detection main board 3 and the lower end of the signal detection main board 4. A rotating shaft is fixedly installed inside the elliptical disk 22 and the rotating shaft rotates through the card housing 1. A swing arm 20 is fixedly sleeved on the outer surface of the two rotating shafts, and a fixing rod 21 is fixedly installed between the two swing arms 20. A pushing component 12 is installed on the outside of the elliptical disk 22, which can simultaneously rotate the two swing arms 20 through the fixing rod 21.

[0023] Please see Figure 3 The push assembly 12 shown in the figure includes slide rods 16 fixedly installed at the upper and lower ends of the adapter 6. Connecting rods 18 are installed at both ends of the elliptical disk 22, and the connecting rods 18 are slidably installed inside the clamp housing 1 through the bracket. A clamping block 19 is fixedly installed at the end of the connecting rod 18 near the elliptical disk 22, and the clamping block 19 is slidably engaged with the outside of the elliptical disk 22. A semi-circular arc sleeve block 17 is fixedly installed at the end of the connecting rod 18 away from the elliptical disk 22, and the semi-circular arc sleeve block 17 is slidably engaged with the slide rod 16. During the rotation of the elliptical disk 22, the two connecting rods 18 can be pushed, and the two adapters 6 can be pushed simultaneously through the slide rods 16.

[0024] Please see Figure 3In the figure, the swing angle of the swing arm 20 is less than 90 degrees. In order to ensure that the elliptical disk 22 and the swing arm 20 can automatically reset under the action of the two tension components 13 after the two adapters 6 are effectively pushed by the connecting rod 18.

[0025] Please see Figure 3 In the figure, the connecting rod 18 is collinear with the transverse centerline of the clamp housing 1, ensuring the stability of the connecting rod 18 in pushing the adapter 6.

[0026] The working principle of reducing the number of cards and saving daily maintenance costs is as follows: During the testing process, the user can first test one of the test points directly through the adapter 6 connected to both ends of the signal detection mainboard 3. When testing another test point, the user needs to rotate the fixing rod 21 to make the elliptical disk 22 rotate. During the rotation of the elliptical disk 22, the two adapters 6 can be pushed synchronously through the two connecting rods 18. Figure 7 As shown, during the sliding process of the two adapters 6 towards the outside of the sleeve frame 23, the octagonal blocks 29 and octagonal sliders 32 at the front and rear ends of the adapters 6 slide inside the cavity. Under the guidance of the guide slider 27 and the guide plate 30, the octagonal blocks 29 and octagonal sliders 32 slide downwards and can slide to the lower part of the cavity. During the sliding process, the arc top slider 36 and the guide plate 31 distributed below will also be pushed. When the entire adapter 6 is successfully moved to the lower part of the sleeve frame 23, the swing arm 20 is released. The adapter 6 moves and slides towards the signal detection main board 4 under the action of the tension spring 26, and the signal conversion output port 8 is plugged into the signal port 5 outside the signal detection main board 4. At this time, the switching of different signal detection of the card is completed, and the other measuring point can be detected and processed through the two adapters 6 in this state. When the elliptical disk 22 is triggered to rotate again, the octagonal block 29 and the octagonal slider 32 slide towards the upper part of the sleeve frame 23 under the action of the guide plate 30 and the guide slider 27 distributed at the lower part. During the sliding process, the octagonal slider 32 can be compressed against the spring 33 by the cooperation of the two spliced ​​arc top sliders 36, so that the octagonal slider 32 passes over the baffle 39. After the adapter 6 is successfully moved to the upper part of the sleeve frame 23, the swing arm 20 is released and moves under the action of the tension spring 26, so that it can cooperate with the signal ports 5 at both ends of the signal detection main board 3 again. The above method allows a single card to perform switching detection for two measuring points, eliminating the need to carry multiple cards and effectively reducing the cost of measuring point detection for steam turbine units.

[0027] Example 2

[0028] Please see Figure 8 and Figure 9This embodiment further explains Example 1. The limiting component 15 includes octagonal blocks 29 fixedly installed at both ends of the adapter 6. An octagonal slider 32 is slidably installed on the end of the octagonal block 29 away from the adapter 6 via a sliding rod. A spring 33 is fixedly installed between the octagonal block 29 and the octagonal slider 32. The octagonal block 29 and the octagonal slider 32 are slidably embedded in the groove formed by the guide slider 27, the isosceles triangle block 28 and the cavity. A straight groove 34 is provided on the side of the octagonal slider 32 that fits against the sleeve frame 23. A straight bar 38 is fixedly installed on the arc surface of the arc top slider 36, and the straight bar 38 is slidably embedded with the straight groove 34. Rounded chamfers are provided on the two sides of the octagonal slider 32 near the end of the straight groove 34. The rounded chamfers are designed to ensure that the octagonal slider 32 can smoothly slide to the arc surface of the arc top slider 36 during the movement.

[0029] In this embodiment: through the action of the straight bar 38 and the straight groove 34, when the octagonal slider 32 slides to the surface of the arc top slider 36, the straight groove 34 and the straight bar 38 are engaged to ensure the stability of the sliding of the octagonal slider 32, so that the octagonal slider 32 and the regular octagonal block 29 can smoothly pass over the obstruction of the baffle 39.

It includes a card housing 1, with a mounting plate 2 fixedly installed at the center of the housing 1. Signal detection main board 3 and signal detection main board 4 are bolted to the upper and lower ends of the mounting plate 2, respectively.

Adapters 6 are movably installed at both ends of the mounting plate 2, with a signal output port 8 located at the end of the adapter 6 closest to the signal port 5. The other end of the adapter 6 is equipped with a signal input port 7, the signal port 5 and the signal output port 8 are movably fitted together, and a silicone corrugated sleeve 9 is fixedly installed between the outer surface of the signal input port 7 and the card housing 1; the switching mechanism 10, which can switch the insertion position of the signal input port 7, is installed on the outside of the adapter 6; the toggle mechanism 11, which can simultaneously activate the switching mechanisms 10 on the outside of the two adapters 6, is installed inside the card housing 1, wherein the adapter 6 is a connector converter in the prior art.

[0032] In this embodiment, the function of the silicone corrugated sleeve 9 is to ensure that the adapter 6 and the card housing 1 are sealed during the switching and moving process, so as to prevent dust, impurities or moisture from entering the interior of the card housing 1 and causing damage to the signal detection motherboard 1 3 and the signal detection motherboard 2 4.
