[0040] Reference will now be made to Figure 1-Figure 3 The water turbine generator braking system monitoring device according to the embodiments of the present application includes a plurality of key components to ensure the effective implementation of its functions. Specifically, it includes a magnetic shielding shell 100, an internal damping support 200, a humidity adjusting device 300, and a monitoring sensor main body 400. The above components ensure the good performance, stability and anti-interference of the device through precise design and cooperation, and are suitable for complex and harsh working environments.

[0041] The water turbine generator braking system monitoring device includes:

[0042] The magnetic shielding shell 100 is fixedly connected with the mounting bracket, and is used to provide an electromagnetic interference-proof environment to protect the monitoring device from external electromagnetic influence and resist physical impact, thereby ensuring the authenticity and accuracy of the monitoring data. The magnetic shielding shell 100 is itself strong and is firmly connected with the mounting bracket, ensuring that the monitoring device can be reliably positioned at a predetermined position of the water turbine generator braking system;

[0043] The internal damping support 200 is fixedly installed inside the magnetic shielding shell 100, and is used to dampen the monitoring sensor main body 400 installed thereon, so that the monitoring data can accurately reflect the operating state of the braking system without being affected by the deviation caused by the interference source;

[0044] The humidity adjusting device 300 is installed inside the magnetic shielding shell 100, and can monitor and adjust the humidity inside the magnetic shielding shell 100, thereby controlling the humidity level in the closed environment to be within a suitable range to ensure that the electronic components work normally without short circuit or corrosion, thereby ensuring the reliability of the overall monitoring work;

[0045] The monitoring sensor main body 400 is installed on the internal damping support 200, and the monitoring device main body is connected to the various auxiliary structures mentioned above to achieve more accurate monitoring. This component is used to sense and record various real-time parameters related to the braking system. It must have high sensitivity and response speed, as well as sufficient stability and the ability to work continuously for a long time. Among them, the monitoring sensor can be one of an ultrasonic sensor, a magnetic sensor or an optical sensor. When it is an optical sensor, a light-transmitting layer is provided on the magnetic shielding shell 100.

[0046] The utility model discloses a practical understanding through the utility model discloses a magnetic shielding shell 100 realizes the shielding to the external magnetic interference to set up the internal damping support 200 in the inside of magnetic shielding shell 100 to make the installation convenient, slow down the vibration of the vast majority, and the magnetic shielding shell 100 can isolate the moisture in the vast majority of air, and a small part of moisture can be absorbed and adjusted through humidity adjusting device 300 to ensure the monitoring precision of detection sensor main part, the utility model discloses a kind of water turbine generator brake system monitoring device provided by the above structure can resist the influence of magnetic force, vibration and humidity, to realize accurate monitoring. Specifically, the specific method for realizing the device can be that when selecting material, magnetic shell shell is made of material with excellent electromagnetic shielding property;The support part is made of elastic or buffer material with excellent damping performance to realize vibration signal isolation;Humidity regulating unit, etc. with automatic humidifying or dehumidifying mechanism is introduced to accurately measure moisture content. And signal acquisition and data analysis are completed by using temperature or air flow speed determination module based on resistance change principle, or by means of piezoelectric crystal resonance frequency change micro pressure sensor. All these need to be designed and improved in a targeted manner to realize the function of accurate monitoring in combination with the possible conditions under the specific working conditions of water turbine generator set.

[0047] Magnetic shielding shell 100 is made of special high-strength moisture-proof material, which can effectively resist the influence of external electromagnetic interference on the monitoring accuracy of the device, and can also resist the damp erosion effect in the high-humidity environment near the water turbine for a long time, ensuring the continuity and accuracy of equipment operation, prolonging the service life of the equipment, and improving the application range and reliability.

[0048] It should be noted that the special high-strength moisture-proof material used may be based on a composite resin system combined with high-performance metal powder or use fiber-reinforced plastic as a base material. Through necessary physical and chemical performance improvement process optimization of different types of materials, such as adding nanoparticles to improve interfacial adhesion, adding coating to improve corrosion resistance, etc. The material finally selected and applied in the manufacture of the monitoring device magnetic shielding shell 100 has excellent moisture resistance and sufficient structural stability. The above embodiments provide more reliable support for the long-term and efficient operation of the water turbine generator brake system.

[0049] Please continue to see Figure 1 、 Figure 2As shown, according to one embodiment of the present application, the internal damping support 200 is provided with a plurality of damping pads 210, the damping pad 210 is a component made of loose porous material, the above structure effectively relieves and isolates the vibration and impact force applied to the device from the outside, greatly improves the overall stability and durability of the device, and the loose porous structure of the damping pad 210 can absorb moisture in the air, thereby ensuring the durability of the present application. Because the damping pad 210 made in the above manner can ensure the long-term reliable operation of the monitoring device, it also has certain self-regulating function, which can automatically adapt and adjust the optimal damping state according to the different surrounding environment. In addition, the multi-level design of the damping system helps to disperse and weaken the influence of vibration waves in different types of frequency range.

[0050] Specifically, a variety of substances meeting the above physical performance requirements such as silica gel, EPDM or polyurethane foam with high elasticity and energy absorption capacity can be prepared into damping elements of different specifications and hardness, and reasonably distributed and placed in the internal damping support 200, so as to ensure that the monitoring device can maintain good working performance and prolong service life whether it is running at low speed or high speed.

[0051] Please continue to see Figure 1 、 Figure 2 As shown, according to another embodiment of the present application, the humidity adjusting device 300 comprises:

[0052] The dehumidifying structure 310 is opposite to the plurality of damping pads 210, so that the dehumidifying structure 310 can remove the moisture absorbed by the damping pad 210 inside the magnetic shielding shell 100, avoiding the problem of equipment performance degradation caused by excessive moisture;

[0053] The monitoring structure 320 is used for monitoring the humidity inside the magnetic shielding shell 100;

[0054] The control structure 330 is electrically connected with the dehumidifying structure 310 and the monitoring structure 320, and the control structure 330 can control the dehumidifying structure 310 according to the monitoring of the monitoring structure 320.

[0055] Through the above structure, the damping pad 210 can absorb the water vapor inside the magnetic shielding shell 100, when the damping pad 210 absorbs part of the water vapor, the humidity inside the magnetic shielding shell 100 increases, so that the monitoring structure 320 detects the humidity change state inside the magnetic shielding shell 100, and transmits the humidity change state to the inside of the control structure 330, and the control structure 330 starts or stops the dehumidification structure 310 according to the humidity change state, and the dehumidification structure 310 can simultaneously dehumidify the water vapor absorbed by the damping pad 210 and the water vapor in the air inside the magnetic shielding shell 100. Specifically, the actual humidity value is obtained by arranging a high-precision humidity sensor 321 in a specific area inside the magnetic shielding shell 100, and using a single-chip microcomputer with programmable logic control function as the core component of the controller. Once the sensor measures that the humidity exceeds the set standard range, a preset response scheme is triggered: a small high-efficiency energy-saving drying fan is started to speed up air circulation and reduce humidity deposition. In this way, the humidity control inside the utility model is ensured within a certain range, thereby realizing the function of accurate detection.

[0056] Please continue to see Figure 1 and Figure 2 As shown in FIG. 12, according to still another embodiment of the present application, the dehumidification structure 310 comprises:

[0057] The dehumidification bag 311 is filled with a moisture-absorbing material inside, and the dehumidification bag 311 is placed inside the magnetic shielding shell 100. The dehumidification bag 311 is loaded with a material with moisture-absorbing capacity such as a desiccant inside. Such a moisture-absorbing material can effectively absorb excess moisture from the environment; and in order to increase the flowability and humidity adjustment effect of the environment around the dehumidification bag 311;

[0058] The fan 312 is used to create a low-pressure area near the dehumidification bag 311. When the fan 312 is working, it can create a local low-pressure area to promote environmental air circulation, which is conducive to accelerating the migration of moisture in the air to the dehumidification bag 311, thereby improving the dry and wet humidity control effect of the internal environment of the monitoring device.

[0059] Specifically, silica gel or molecular sieve can be used as the moisture-absorbing material in the dehumidification bag 311. Silica gel has excellent moisture absorption and chemical stability, and can exhibit good moisture absorption efficiency in various temperature and humidity environments, and is particularly suitable for use in water turbine generators with variable environments; molecular sieve is also an effective choice, which can not only effectively absorb water molecules in the air, but also can remove small molecular compounds more difficult to remove than water vapor. In addition, the selected fan 312 should have the characteristics of low power consumption and high reliability, so as to run stably for a long time without causing additional faults or noise interference.

[0060] Please continue to see Figure 1 , Figure 2 As shown, according to an optional embodiment of the present invention, the internal vibration-damping support 200 is arranged between the fan 312 and the dehumidification bag 311, and the wind direction of the fan 312 is toward the internal vibration-damping support 200. Through the above structure, the fan 312 can remove the water vapor absorbed by the vibration-damping pad 210 in the internal vibration-damping support 200, thereby ensuring the vibration reduction effect.

[0061] Specifically, the internal vibration-damping support 200 can be manufactured from non-metallic materials with excellent elastic deformation and a long lifespan. Furthermore, its geometry and dimensions can be adjusted based on specific installation requirements and operating environment factors, such as using a corrugated or grid-like structure, to achieve optimal vibration reduction and ensure smooth airflow, thereby improving the overall performance and reliability of the monitoring device. After finalizing the design, it is necessary to ensure that all relevant interfaces are perfectly aligned, balancing aerodynamic properties with mechanical stability to support long-term, trouble-free operation.

[0062] Please continue to see Figure 1 、 Figure 2 As shown, according to a further embodiment of the present invention, a compartment door 110 is opened on the side wall of the magnetic shielding shell 100, and a sealing strip 120 is provided on the compartment door 110. The compartment door 110 is used to allow the staff to replace the dehumidification bag 311, so that the dehumidification bag 311 can play a better role. At the same time, in order to ensure sealing, a sealing strip 120 is provided on the compartment door 110 for sealing, thereby preventing water vapor in the external air from entering the interior of the magnetic shielding shell 100 through the gap of the compartment door 110.

[0063] Specifically, the sealing strip 120 can be made of rubber or other flexible materials suitable for operating in environments with high pressure, humidity, or significant temperature fluctuations. By appropriately designing the thickness and hardness of the sealing strip 120, the door 110 can be securely attached to the edge of the magnetic shielding housing 100 without causing additional stress damage. This ensures a good physical seal and a long service life during installation and opening and closing. A rational cross-sectional design ensures that the door 110 automatically and tightly presses against the housing interface when closed without applying any additional force, thereby enhancing waterproof and dustproof properties.

[0064] Please continue to see Figure 1 and Figure 2 As shown, in an optional embodiment of the present invention, the monitoring structure 320 includes:

[0065] Humidity sensor 321, humidity sensor 321 is installed in the magnetic shielding enclosure 100, humidity sensor 321 is used to continuously monitor the humidity level of the air inside the magnetic shielding enclosure 100, humidity sensor 321 is designed and positioned inside the magnetic shielding enclosure 100 without interfering with the overall structure to ensure its accuracy while not affecting the electromagnetic compatibility of the system;

[0066] The processor 322 is electrically connected to the humidity sensor 321 and the control structure 330. The processor 322 can convert the humidity information monitored by the humidity sensor 321 into an electrical signal and transmit it to the control structure 330, so that the control structure 330 can adjust the dehumidification structure 310 according to the humidity state monitored by the humidity sensor 321 and start or shut down the dehumidification structure 310.

[0067] The protective shell 323 is installed in the shielding shell. The processor 322 and the main body of the humidity sensor 321 are installed in the protective shell 323. The probe of the humidity sensor 321 extends out of the protective shell 323. The protective shell 323 is used to prevent water vapor from corroding the processor 322 and the humidity sensor 321, thereby improving durability.

[0068] Specifically, in order to prevent the external environment from causing physical damage to sensitive components, especially the processor 322 and the humidity sensor 321, and to prevent dust and other pollutants from entering and causing deviations in data collection and calculation, a protective shell 323 is deliberately added at an appropriate position in the magnetic shielding shell 100. The protective shell 323 provides a defense for the main part of the humidity sensor 321. The probe of the humidity sensor 321 needs to extend to the outside of the protective shell 323 in order to effectively sense the humidity changes within the target monitoring range. At the technical implementation level, a waterproof sealing material can be used to make this protective cover and holes can be accurately opened at the corresponding positions to ensure that a good sealing effect is achieved while allowing the probe to fully sense changes in humidity. In this way, through a series of hardware design optimizations, the final product is more suitable for complex and harsh power station environments.

[0069] Please continue to see Figure 2 and Figure 3As shown, in some examples of the present invention, the magnetic shielding shell 100 is provided with an interlayer, and the interlayer is filled with a magnetic shielding material 130. A hydro-generator braking system monitoring device of the present application further includes one or more artificially manufactured gap areas designed inside the magnetic shielding shell 100, called interlayers. The purpose of this interlayer is to accommodate materials that can enhance or improve the magnetic shielding effect of the shell. The magnetic shielding material 130 is usually selected to have high magnetic permeability and low eddy current loss characteristics. This can not only effectively reduce the impact of external environmental magnetic field interference on internal circuits and components, but also improve the operational reliability and safety of the overall system. The specific choice of magnetic shielding material depends on the actual working conditions and the different requirements for the expected shielding effect; for example, in certain application scenarios, if it is necessary to shield magnetic fields with higher frequency changes, soft magnetic alloys or ferromagnetic powder core materials can be considered.

[0070] Specifically, manufacturers can secure the sandwich structure to the inner wall of the magnetic shielding enclosure 100 through welding or clamping, and then fill it with a suitable thickness of magnetic material to achieve optimal shielding efficiency. By carefully calculating the geometric dimensions and layout of the magnetic filler, optimal electromagnetic shielding performance can be achieved without affecting the normal operation of other functional components of the equipment. This design solution is crucial for ensuring the stable and efficient operation of the dynamic braking system, and is particularly suitable for applications requiring demanding or specialized environments.
