Description

Technical Field

[0001] This application relates to the field of vibration sensor protection technology, and in particular to a vibration sensor protective cover. Background Technology

[0002] Pumped storage hydroelectric power utilizes electricity generated during periods of low electricity demand to pump water into an upper reservoir. During periods of high electricity demand, the water stored in the upper reservoir is released into a lower reservoir to generate electricity. It is also known as energy storage power generation. It can convert excess electricity during periods of low grid load into high-value electricity during periods of high grid load. It is suitable for frequency and phase regulation, can be used to stabilize the frequency and voltage of the power system, is suitable for emergency backup, and can also improve the efficiency of thermal power plants and nuclear power plants in the power system.

[0003] Vibration sensors are frequently installed at pumped storage power stations for monitoring purposes. These sensors are typically placed on foundational components such as the generator stator base, upper and lower frames, and the turbine chamber roof to monitor various axial and radial data of the generator. However, because these sensors are usually installed in locations that are easy to fix and maintain, and because their connectors are relatively fragile, maintenance personnel are highly susceptible to accidental damage during equipment maintenance, leading to the loss of unit monitoring data.

[0004] Some technologies include a protective cover on the outside of the vibration sensor, such as patent CN108663109B, which provides a protective device for the sensor. However, this is inconvenient for connecting the vibration sensor to the outside world and for observing the status of the internal vibration sensor. The vibration sensor can only be repaired by removing the protective cover. Therefore, there is an urgent need for a more convenient and reliable protective cover for vibration sensors.

[0027] The following describes specific embodiments in conjunction with... Figures 1 to 3 The technical solution of this application will be described in further detail.

[0028] Some embodiments of this application provide a vibration sensor protective cover, such as Figure 1 and Figure 2 As shown, it includes: a base 1 for supporting a vibration sensor 3; a cover 2 detachably connected to the base 1, the cover 2 having an internal accommodating space for accommodating the vibration sensor 3; the cover 2 includes two first sidewalls 2-1 arranged opposite each other along a first direction, two second sidewalls 2-2 arranged opposite each other along a second direction, and a top wall 2-3 connecting the first sidewalls 2-1 and the second sidewalls 2-2, the first direction and the second direction being perpendicular to each other, wherein a first notch 2-4 is provided in the lower middle part of one of the first sidewalls 2-1, and a second notch 2-5 is provided in the upper part, the first notch 2-4 and the second notch 2-5 being connected, the width of the second notch 2-5 being greater than the width of the first notch 2-4; a third notch 2-6 is provided in the upper part of each of the two second sidewalls 2-2, and the two third notches 2-6 are respectively connected to the second notches 2-5.

[0029] like Figure 1 As shown, the vibration sensor protective cover includes a base 1 and a cover 2, the material of which is, for example, metal, but is not specifically limited. In the figure, direction D1 is the first direction, and direction D2 is the second direction.

[0030] like Figure 3 As shown, the base 1 is, for example, a plate-like structure, and the thickness of the base 1 is, for example, 15mm, etc., which is not specifically limited. The base 1 can support and fix the vibration sensor 3, and the base 1 can be welded to the part to be measured to transmit vibration.

[0031] like Figure 2 As shown, the cover 2 is a hollow structure. The height of the cover 2 is greater than the height of the vibration sensor 3. The cover 2 includes two first side walls 2-1, two second side walls 2-2, and a top wall 2-3. The wall thickness is, for example, 1 mm, etc., and is not specifically limited. The first side walls 2-1, the second side walls 2-2, and the top wall 2-3 form a space to accommodate the vibration sensor 3, avoiding accidental contact and damage to the vibration sensor 3 by personnel, and ensuring reliable monitoring.

[0032] The cover 2 and the base 1 are detachably connected, for example by bolt connection or snap-fit, etc., which is not limited to this, so that the vibration sensor 3 can be easily replaced.

[0033] like Figure 2As shown, a second notch 2-5 is formed on the upper part of the first sidewall 2-1, and a third notch 2-6 is formed on the upper part of the second sidewall 2-2. The second notch 2-5 and the third notch 2-6 can be, for example, rectangular notches, etc., without specific limitations. The second notch 2-5 and the third notch 2-6 are connected to provide as much space as possible for the vibration sensor 3 to be connected to external wiring, and also for ease of operation. The second notch 2-5 is only provided on one of the first sidewalls 2-1, which ensures the stability of the top wall 2-3, thus better protecting the vibration sensor 3.

[0034] A first notch 2-4 is formed in the lower middle part of the first sidewall 2-1. The first notch 2-4 may be, for example, a rectangular notch, but the specific form is not limited.

The first notch 2-4 and the second notch 2-5 are connected. This allows for a complete observation of the internal vibration sensor 3 from one side of the cover 2. If loosening occurs, the vibration sensor 3 can be adjusted promptly. Simultaneously, it ensures the structural strength of the first sidewall 2-1, thus better protecting the vibration sensor 3. The length of the first notch 2-4 can be greater than the height of the vibration sensor 3, further protecting the sensor.

[0035] This vibration sensor protective cover has a simple structure, is easy to manufacture, offers good safety and high reliability, and extends the service life of the vibration sensor. It effectively solves the problem of sensor damage caused by accidental contact or stepping by maintenance personnel. The protective cover can withstand mechanical impacts, protecting the sensor from external force damage and extending its lifespan.

[0045] The width of the first connecting part 1-2 is, for example, 30mm, and the width of the supporting part 1-1 is, for example, 50mm, etc., but the specific width is not limited. Figure 3As shown, the width of the first connecting part 1-2 is smaller than the width of the support part 1-1, and the first connecting part 1-2 is located at the center of the top edge of the support part 1-1 to ensure the structural strength of the base 1.
