Description

Technical Field

[0001] This utility model belongs to the field of hydrogen leakage monitoring technology for generator cooling water, specifically a device for monitoring hydrogen leakage in generator cooling water. Background Technology

[0002] The generator stator cooling water hydrogen leakage monitoring device is a device used to monitor hydrogen leakage in the generator stator cooling water system in real time. The device usually adopts advanced sensor technology and data analysis algorithms, which can accurately measure the dissolved hydrogen concentration at the stator cooling water inlet and outlet, and calculate the amount of hydrogen leakage.

[0003] In existing hydrogen leakage monitoring devices, the detection head measures the dissolved hydrogen concentration at the inlet and outlet of the constant cooling water, and the leakage amount is calculated using a hydrogen leakage monitoring sensor. However, during operation, because the hydrogen sensor isolates water through a diaphragm before detecting the hydrogen content, after prolonged use, the diaphragm cannot completely isolate water vapor in the sampled gas, leading to inaccurate hydrogen leakage detection results. This can cause short circuits and damage to the generator, necessitating probe replacement. Since the probe is welded to the inner wall of the water tank, replacement is cumbersome and time-consuming. Therefore, improvements are needed. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a device for monitoring hydrogen leakage in generator cooling water.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a generator constant cooling water hydrogen leakage monitoring device, comprising a water tank, wherein a hydrogen leakage monitoring mechanism is provided on the top of the water tank, and a disassembly and assembly assembly located outside the hydrogen leakage monitoring mechanism is provided on the top of the water tank.

[0006] The disassembly and assembly assembly includes a locking block, the inner side of which is movably connected to the outer surface of the hydrogen leakage monitoring mechanism, and a sealing ring is provided on the inner side of the locking block.

[0007] Preferably, the water tank has a limiting groove located above and below the locking block, and the inner wall of the limiting groove is movably connected to the outer surface of the locking block.

[0008] Preferably, there are two card blocks, located on both sides of the hydrogen leakage monitoring mechanism.

[0009] Preferably, the disassembly and assembly assembly includes a rotating block, the inner side of which is provided with a threaded rod located in the inner cavity of the water tank, and the outer surface of the threaded rod is threaded with a movable frame.

[0011] Preferably, a spring is provided on the outside of the card block, and the other end of the spring is connected to the inner wall of the water tank.

[0012] Preferably, the hydrogen leakage monitoring mechanism includes a hydrogen leakage monitoring probe, which is movably connected to the outside of the water tank, and a hydrogen leakage monitoring sensor is provided on the top of the hydrogen leakage monitoring probe.

[0013] Preferably, the outer surface of the hydrogen leakage monitoring mechanism is provided with protrusions, which are evenly distributed on the outside of the hydrogen leakage monitoring mechanism.

[0014] Preferably, the hydrogen leakage monitoring mechanism has a circular groove on the outside of the card block, and the groove is adapted to the size of the sealing ring.

[0015] Preferably, there are two card blocks, and the inner side of the two card blocks is round after they are combined.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model is equipped with a locking block and a movable frame. Rotating the locking block moves the movable frame via the threaded rod, which in turn moves the locking block within the limiting groove, releasing it from the hydrogen leakage monitoring mechanism. Simultaneously, the locking block moves the sealing rings from both sides of the hydrogen leakage monitoring mechanism, completely removing them from obstruction.

[0025] 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.

[0026] Example 1

[0027] like Figures 1 to 5 As shown, this is the first embodiment of the present invention, which provides a generator constant cooling water hydrogen leakage monitoring device, including a water tank 1, a hydrogen leakage monitoring mechanism 2 is provided on the top of the water tank 1, and a disassembly and assembly assembly 3 is provided on the top of the water tank 1 outside the hydrogen leakage monitoring mechanism 2.

[0028] The disassembly and assembly component 3 includes a locking block 301. The inner side of the locking block 301 is movably connected to the outer surface of the hydrogen leakage monitoring mechanism 2. A sealing ring 308 is provided on the inner side of the locking block 301. A limiting groove 302 located above and below the locking block 301 is provided inside the water tank 1. The inner wall of the limiting groove 302 is movably connected to the outer surface of the locking block 301.

[0029] By rotating the disassembly assembly 3, the locking block 301 moves inside the limiting groove 302. Due to the design of the limiting groove 302, the locking block 301 is limited by the limiting groove 302 during movement to prevent positional deviation. The limiting groove 302 also drives the sealing ring 308 to move outward. The sealing ring 308 moves out from the outside of the hydrogen leakage monitoring mechanism 2, releasing the locking seal on the hydrogen leakage monitoring mechanism 2. This makes it easier for the operator to remove the hydrogen leakage monitoring mechanism 2 from the water tank 1 for easy detection of the detection head.

[0030] Example 2

[0031] like Figure 2 and Figure 4 As shown, this embodiment includes the features of embodiment 1, the distinguishing technical feature being that there are two card blocks 301, and the two card blocks 301 are located on both sides of the hydrogen leakage monitoring mechanism 2;

[0032] The design of the two locking blocks 301 facilitates the fixing of the end of the hydrogen leakage monitoring mechanism 2 inside the water tank 1, thereby improving the fixing effect between the water tank 1 and the hydrogen leakage monitoring mechanism 2.

[0033] Among them, the disassembly and assembly component 3 includes a rotating block 303, and a threaded rod 304 located in the inner cavity of the water tank 1 is provided on the inner side of the rotating block 303. A movable frame 305 is threadedly sleeved on the outer surface of the threaded rod 304.

[0034] The rotating block 303 drives the movable frame 305 to move within the water tank 1 via the threaded rod 304, which facilitates the release of the hydrogen leakage monitoring mechanism 2 from its fixation. This allows the operator to easily replace the end of the hydrogen leakage monitoring mechanism 2, thus avoiding any impact on the monitoring of hydrogen leakage in the constant cooling water.

[0035] The movable frame 305 has a movable block 306 on its inner side, and the other end of the movable block 306 is hinged to the outer side of the locking block 301.

[0036] When the movable frame 305 moves, it will drive the movable block 306 to move as well. Due to the hinge between the movable block 306 and the locking block 301, the movable block 306 will drive the locking block 301 to move out from both sides of the hydrogen leakage monitoring mechanism 2, releasing the locking of the hydrogen leakage monitoring mechanism 2. This makes it easier for the operator to remove the hydrogen leakage monitoring mechanism 2 from the water tank 1 for replacement. This avoids the hydrogen leakage monitoring mechanism 2, which cannot completely isolate the water vapor contained in the sampled gas, causing inaccurate hydrogen leakage content detection results due to prolonged use. In addition, water will accumulate inside the hydrogen leakage monitoring mechanism 2 after long-term use, ultimately shortening the probe's lifespan.

[0037] Among them, a spring 307 is provided on the outside of the card block 301, and the other end of the spring 307 is connected to the inner wall of the water tank 1;

[0038] At this time, since the spring 307 is in a compressed state, it will apply an inward pressure to the locking block 301, thereby continuously squeezing the locking block 301 to lock the hydrogen leakage monitoring mechanism 2, so as to prevent the connection between the locking block 301 and the hydrogen leakage monitoring mechanism 2 from becoming loose.

[0039] Among them, the hydrogen leakage monitoring mechanism 2 includes a hydrogen leakage monitoring probe, which is movably connected to the outside of the water tank 1, and a hydrogen leakage monitoring sensor is installed on the top of the hydrogen leakage monitoring probe.

[0040] The amount of hydrogen leakage in the generator's stator cooling water is monitored by a hydrogen leakage monitoring probe. The hydrogen leakage monitoring sensor continuously collects and analyzes data to promptly capture hydrogen leakage trends and provide early warnings so that appropriate measures can be taken.

[0041] Among them, the outer surface of the hydrogen leakage monitoring device 2 is provided with protrusions, which are evenly distributed on the outside of the hydrogen leakage monitoring device 2;

[0042] By setting multiple protrusions, the contact area is increased and friction is provided when disassembling the hydrogen leakage monitoring mechanism 2, making it easier for operators to remove the hydrogen leakage monitoring mechanism 2.

[0043] Among them, the hydrogen leakage monitoring mechanism 2 has a circular groove on the outside of the card block 301, and the circular groove is adapted to the size of the sealing ring 308.

[0044] When the locking block 301 moves the sealing ring 308 inward, it engages the sealing ring 308 into the circular groove, thus achieving a good sealing effect.

[0045] There are two card blocks 301, and the inner side of the two card blocks 301 is a circular hole after they are combined.

[0046] The round hole allows the hydrogen leakage monitoring device 2 to be easily attached to the inside of the water tank 1, and the sealing ring 308 inside the round hole facilitates the sealing between the water tank 1 and the hydrogen leakage monitoring device 2 to prevent leakage.

[0047] The upper and lower surfaces of the circular groove are set as inclined surfaces;

[0048] When the locking block 301 pushes the sealing ring 308 into the circular groove, the sealing ring 308 will press against the inclined surface of the circular groove, causing the sealing ring 308 to deform. This facilitates the sealing ring 308 entering the circular groove. At the same time, the elastic reset caused by the deformation presses against the inclined surface, making the sealing ring 308 fit tightly against the circular groove to prevent leakage.

[0049] Working principle and usage process of this utility model:

[0050] First, the operator rotates the rotating block 303, which drives the movable frame 305 to move within the water tank 1 via the threaded rod 304. The movement of the movable frame 305 then moves the movable block 306. Due to the hinge between the movable block 306 and the locking block 301, the movable block 306 drives the locking block 301 to move within the limiting groove 302, releasing it from the hydrogen leakage monitoring mechanism 2. Simultaneously, the elastic force of the spring 307 makes the locking block 301 easier to move. Furthermore, the locking block 301 drives the sealing ring 308 to move out from both sides of the hydrogen leakage monitoring mechanism 2, completely releasing it from obstruction. This allows the operator to easily remove the hydrogen leakage monitoring mechanism 2 from the outside of the water tank 1, facilitating the replacement of the probe on the hydrogen leakage monitoring mechanism 2 and preventing inaccurate hydrogen leakage monitoring due to prolonged use.
