Description

Technical Field

[0001] This application relates to the field of data acquisition technology, specifically to a physical field data acquisition device for a water supply pump in a hydropower plant. Background Technology

[0002] In hydropower plants, water pumps are responsible for drawing water from lower to higher elevations, providing essential water support for power generation, cooling, lubrication, and other processes. The physical field data of these water pumps includes multi-dimensional information such as temperature, pressure, flow rate, water quality, and vibration fields during operation. This data reflects the physical characteristics of the pumps during actual operation and is crucial for evaluating their performance, health status, and developing optimized operating strategies. Collecting this data allows for the timely detection of any abnormal pump operation, thus ensuring the stable operation of the hydropower plant.

[0003] Currently, the physical field data acquisition device for water supply pumps in hydropower plants typically uses a combination of multiple sensors, such as temperature sensors, pressure sensors, flow sensors, water quality sensors, and vibration sensors. These sensors are installed on the pipes connected to the outlet of the water supply pump to complete the acquisition of physical field data of the water supply pump.

[0004] However, the sensors in existing data acquisition devices are typically directly exposed to the external environment after installation, and their prominent installation positions make them susceptible to direct impacts from external objects. This can lead to damage to the sensor casing, displacement of internal components, or loosening of wiring connections, resulting in a high sensor failure rate. Once a sensor is damaged, inaccurate data collection or even complete failure to collect data can occur, affecting the effective monitoring of the physical field data of the water supply pump and posing potential safety hazards to the normal operation of the water supply pump.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Unless otherwise specified, the above-mentioned orientational descriptions can be flexibly set in actual application, provided that the relative positional relationships shown in the accompanying drawings are satisfied.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] See Figure 1 , Figure 2 This application provides a physical field data acquisition device for a water supply pump in a hydropower plant, including a connecting pipe assembly 1, which includes a main pipe body 11 and a data acquisition component 2 on the main pipe body 11; it also includes a support protection assembly 3, which includes two annular protection plates 31 and several protection rods 32; the two protection plates 31 are sleeved on the main pipe body 11 and located on both sides of the data acquisition component 2, and the several protection rods 32 are arranged at intervals along the circumference of the main pipe body 11, with the two ends of each protection rod 32 connected to the outer edges of the two protection plates 31 respectively.

[0042] The connecting pipe assembly 1 includes a main pipe body 11, which is a circular tubular structure open at both ends. The main pipe body 11 can be part of the pipe connected to the outlet of the water supply pump; this structure reduces the number of intermediate connection interfaces and improves installation efficiency. Alternatively, the main pipe body 11 can be an additional structure connected between the outlet of the water supply pump and the pipe. The data acquisition assembly 2 is mounted on the main pipe body 11 and is used to collect physical field data during the operation of the water supply pump.

[0043] The support protection assembly 3 includes two protective plates 31 and several protective rods 32. The protective plates 31 are annular structures, and the protective rods 32 are elongated structures. The two protective plates 31 are spaced apart along the axial direction of the main body 11. The two protective plates 31 are simultaneously fitted onto the main body 11 and fixedly connected to it. The data acquisition assembly 2 is located between the two protective plates 31. The outer edges of the two protective plates 31 are fixedly connected by several protective rods 32, which are arranged circumferentially around the main body 11. The protective plates 31 can be welded to the main body 11 or detachably connected using other structures; the protective rods 32 can be welded to the protective plates 31 or detachably connected using other structures.

[0044] The physical field data acquisition device for a water supply pump in a hydropower plant provided in this embodiment can acquire the physical field data of the water supply pump in real time using a data acquisition component 2. A support protection component 3, mainly composed of two protective plates 31 and several protective rods 32, is installed on the main pipe 11. This protects the data acquisition component 2 within the protective space of the support protection component 3, providing structural shielding and reducing direct collisions with external objects. This significantly reduces the probability of damage to the data acquisition component 2 due to external impacts, thus ensuring effective monitoring of the water supply pump's physical field data. By arranging several protective rods 32 at intervals along the circumference of the main pipe 11, there is space between adjacent protective rods 32. This space not only allows free airflow, facilitating heat dissipation for the data acquisition component 2 during operation and preventing overheating due to heat accumulation, thus extending its service life, but also allows operators to visually observe the operating status of the data acquisition component 2, promptly identify and address potential problems, and reduce maintenance time and costs.

[0045] The physical field data acquisition device for the water supply pump of the hydropower plant provided in this application embodiment can effectively disperse and absorb the impact force when an external object collides with the support protection component 3 during normal operation. This significantly reduces the direct transmission of the impact force to the data acquisition component 2, thereby further ensuring the normal operation of the data acquisition component 2.

[0046] In some embodiments, see Figure 1 , Figure 3The protective plate 31 includes at least two splicing portions 311 sequentially spliced ​​along its circumference, with adjacent splicing portions 311 connected by fastening components 312. Accordingly, this structure facilitates the installation and removal of the protective plate 31. During installation, several splicing portions 311 can be first spliced ​​onto the outer surface of the main pipe 11 to form a ring structure, and then adjacent splicing portions 311 can be connected together by the fastening components 312 to fix it to the main pipe 11. The removal process of the protective plate 31 is the reverse of the installation process and will not be described further here.

[0047] For example, see Figure 1 , Figure 3 The protective plate 31 includes two semi-circular splicing parts 311, which are spliced ​​together to form a circular structure. The two ends of the two splicing parts 311 are connected together by fastening components 312. The splicing part 311 of one of the protective plates 31 can be fixedly connected to the splicing part 311 of the other protective plate 31 by three protective rods 32.

[0048] In some embodiments, see Figure 4 The fastening assembly 312 includes two connecting portions 3121, a fastening bolt 3122 passing through the two connecting portions 3121, and a fastening nut 3123 connected to the end of the fastening bolt 3122. The two connecting portions 3121 are respectively provided on two adjacent splicing portions 311. Each connecting portion 3121 is provided with a bolt hole for the fastening bolt 3122 to pass through. The connecting portion 3121 and the splicing portion 311 can be welded together or integrally formed.

[0049] After two adjacent splicing parts 311 are spliced ​​together, the bolt holes of the two connecting parts 3121 are aligned, and the fastening bolts 3122 are passed through the bolt holes of the two connecting parts 3121 in sequence. Then, the fastening nut 3123 is connected to the end of the fastening bolt 3122. After tightening the fastening nut 3123, the two adjacent splicing parts 311 are fixed together.

[0050] The protective rod 32 and the splicing part 311 can be welded together, or they can be connected using a detachable structure. For example, see... Figure 3 The end of the protective rod 32 is provided with an external thread section, and the splicing part 311 is provided with a through hole for the external thread section of the protective rod 32 to pass through. The external thread section of the protective rod 32 passes through the through hole of the splicing part 311, and two fixing nuts 34 are threadedly connected to the external thread section. The two fixing nuts 34 are located on both sides of the splicing part 311. After tightening the two fixing nuts 34 to clamp the splicing part 311, the protective rod 32 and the splicing part 311 are fixedly connected.

[0051] In some embodiments, see Figure 1 , Figure 3The splicing portion 311 is provided with a support corner plate 33 that contacts the outer surface of the main body 11. For example, a plurality of support corner plates 33 are welded onto the splicing portion 311, and the support corner plates 33 are evenly distributed along the circumference of the splicing portion 311. Accordingly, by setting the support corner plates 33 to contact the outer surface of the main body 11, the pressure of the protective plate 31 on the main body 11 can be effectively dispersed, avoiding damage to the outer surface of the main body 11 due to excessive local pressure.

[0052] In some embodiments, see Figure 1 , Figure 2 The data acquisition component 2 includes a sensor 21. The outer surface of the main body 11 is provided with a connecting valve 12 that communicates with its inner cavity. The connecting valve 12 is connected to the sensor 21 through a connecting pipe 13.

[0053] Correspondingly, sensor 21 is connected to the inner cavity of main pipe 11 via pipe 13 and connecting valve 12. This allows sensor 21 to collect physical field data within main pipe 11 in real time, thereby enabling the acquisition of physical field data for the water supply pump. The connecting valve 12 creates a controllable connection channel between sensor 21 and the inner cavity of main pipe 11, facilitating the maintenance and replacement of sensor 21 and reducing interference with the entire water supply system. During operation, simply closing the connecting valve 12 allows maintenance personnel to perform maintenance and replacement of sensor 21 without affecting the normal operation of main pipe 11.

[0054] The number of sensors 21 may include one, two, or more, depending on the amount of physical field data to be collected, and is not specifically limited here. For example, sensor 21 may include at least one of a temperature sensor, a pressure sensor, a flow sensor, a water quality sensor, and a vibration sensor. The temperature sensor is used to collect water temperature data, the pressure sensor is used to collect water pressure data, the flow sensor is used to collect water flow data, the water quality sensor is used to collect data on pollutants, pH value, dissolved oxygen, and other water quality parameters, and the vibration sensor is used to collect vibration data.

[0055] For example, the sensor 21 includes five sensors, namely a temperature sensor, a pressure sensor, a flow sensor, a water quality sensor, and a vibration sensor. Five connecting valves 12 are evenly distributed around the circumference of the main body 11. The five sensors 21 correspond one-to-one with the five connecting valves 12. Each sensor 21 is connected to the corresponding connecting valve 12 through the connecting pipe 13.

[0056] In some embodiments, see Figure 1The connecting pipe assembly 1 also includes a fixing seat 14 fixed to the outer surface of the main pipe body 11, and the sensor 21 is connected to the fixing seat 14. Accordingly, by setting the fixing seat 14, a stable mounting base for the sensor 21 is provided on the main pipe body 11. When the sensor 21 is mounted on the fixing seat 14, the installation stability of the sensor 21 can be improved, and the sensor 21 can be prevented from loosening or shifting due to vibration during operation.

[0057] For example, see Figure 2 , Figure 5 The fixed base 14 includes a connecting pile 141 connected to the main body 11, a connecting block 142 connected to the connecting pile 141, a vibration damping pile 143 connected to the connecting block 142, and a buffer frame 144 connected to the vibration damping pile 143. The sensor 21 is connected to the buffer frame 144.

[0058] Correspondingly, the sensor 21 and the buffer frame 144 can be connected by snap-fit ​​or bolts, facilitating the quick installation and disassembly of the sensor 21. The buffer frame 144 can be made entirely of elastic buffer material, or it can be made of a steel structure frame and elastic buffer material on its surface. The elastic buffer material has good elasticity and recovery ability, which can absorb and disperse the impact force, reducing the direct damage of vibration to the sensor 21. The buffer frame 144 can be connected to two vibration damping piles 143. The vibration damping piles 143 can adopt a spring damping structure to weaken the transmission of vibration energy. Each vibration damping pile 143 is connected to the connecting pile 141 through a connecting block 142. The connecting pile 141 can be firmly fixed to the outer surface of the main body 11 by welding or gluing. Thus, under the synergistic effect of the vibration damping piles 143 and the buffer frame 144, the impact force generated by vibration can be effectively absorbed and mitigated, significantly reducing the damage of vibration to the sensor 21 and extending its service life.

[0059] In some embodiments, see Figure 1 , Figure 2 The connecting pipe assembly 1 also includes connecting flanges 15 located at both ends of the main pipe body 11 and sealing gaskets 16 located on the sealing surfaces of the connecting flanges 15. The connecting flanges 15 can be welded to the main pipe body 11 or integrally formed. The sealing gaskets 16 include, but are not limited to, spiral wound gaskets, metal gaskets, and O-rings. The sealing gaskets 16 can be installed on the sealing surfaces of the connecting flanges 15 using an embedded structure.

[0060] See Figures 1 to 5 The installation process of the physical field data acquisition device for the water supply pump of the hydropower plant provided in this application embodiment is as follows:

[0061] First, connect the connecting flange 15 and sealing gasket 16 at one end of the main pipe 11 to the flange at the outlet of the water pump using bolts or other fasteners. Then, connect the connecting flange 15 and sealing gasket 16 at the other end of the main pipe 11 to the flange at the inlet of the pipe using bolts or other fasteners. Connect the sensor 21 to the connecting valve 12 on the main pipe 11 through the connecting pipe 13, and install the sensor 21 on the buffer frame 144 of the fixed base 14. Install the protective plate 31 and the protective rod 32 on the main pipe 11 to form the bracket protection assembly 3. After installation, the sensor 21 can be used to collect the physical field data of the water pump in real time.

[0062] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
