Technical Field

[0001] This utility model relates to the field of compressed air energy storage technology, and more specifically, to a high-efficiency data acquisition device for compressed air energy storage systems. Background Technology

[0002] Compressed air energy storage (CAES) is a technology that utilizes electricity generated during off-peak hours to drive an air compressor to compress air, converting electrical energy into pressure energy for storage. During peak hours, the stored compressed air is released through an expander to drive a generator, thus achieving the storage and release of electrical energy.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] The following description, with reference to the accompanying drawings, describes a high-efficiency data acquisition device 1 for a compressed air energy storage system according to an embodiment of the present invention.

[0028] like Figures 1-3 As shown, the high-efficiency data acquisition device 1 for compressed air energy storage system according to an embodiment of the present invention includes a cabinet 10, multiple sliding plates 20, multiple data acquisition modules, and multiple sensors.

[0029] The cabinet 10 has multiple shelves 11, which are spaced apart and divide the space within the cabinet 10 into multiple layer spaces 12. Multiple sliding plates 20 are respectively mounted on the bottom walls of the multiple layer spaces 12. Multiple data acquisition modules are respectively mounted on the multiple sliding plates 20. Multiple sensors are respectively mounted on multiple devices of the compressed air energy storage system and are electrically connected to the multiple data acquisition modules.

[0030] Specifically, the multiple sensors detect the operating parameters of multiple devices in the compressed air energy storage system and send the detection data to the multiple data acquisition modules respectively.

[0031] When maintenance is required on the data acquisition module, the sliding plate 20 can be pulled out and then pushed back in after maintenance is completed.

[0032] According to the embodiment of the present invention, the high-efficiency data acquisition device 1 for compressed air energy storage system, by setting up a cabinet 10 and multiple data acquisition modules, can respectively set up multiple data acquisition modules in different layers 12 within the cabinet 10. In this way, the detection data collected by multiple sensors can be transmitted to multiple data acquisition modules respectively, thereby summarizing the detection data at the high-efficiency data acquisition device 1 for compressed air energy storage system. Compared with the data acquisition devices for compressed air energy storage systems in related technologies, the data acquisition of each device in the compressed air energy storage system can be centrally collected, which facilitates unified monitoring of each device in the compressed air energy storage system, improves the efficiency of data acquisition and equipment control, and facilitates real-time adjustment of the operating status of the compressed air energy storage system, so as to facilitate the stable operation and optimized control of the compressed air energy storage system.

[0033] Furthermore, by setting multiple sliding plates 20 and placing the data acquisition module on the sliding plates 20, the sliding plates 20 can be pulled out when maintenance is required and pushed back after maintenance, thus facilitating the maintenance of the data acquisition module and making it easier to maintain the entire high-efficiency data acquisition device 1 for the compressed air energy storage system.

[0034] Therefore, the high-efficiency data acquisition device 1 for compressed air energy storage system according to the present invention has the advantages of high data acquisition efficiency and convenient maintenance.

[0035] The following description, with reference to the accompanying drawings, describes a high-efficiency data acquisition device 1 for a compressed air energy storage system according to a specific embodiment of the present invention.

[0036] In some specific embodiments of this utility model, such as Figures 1-3 As shown, the high-efficiency data acquisition device 1 for compressed air energy storage system according to an embodiment of the present invention includes a cabinet 10, multiple sliding plates 20, multiple data acquisition modules, and multiple sensors.

[0037] Specifically, the compressed air energy storage system includes at least a compressor, a heat exchanger, an expander, and an air storage chamber.

[0038] The plurality of sensors include a compressor sensor, a heat exchanger sensor, an expander sensor, and a gas storage chamber sensor. The compressor sensor is located on the compressor, the heat exchanger sensor is located on the heat exchanger, the expander sensor is located on the expander, and the gas storage chamber sensor is located on the gas storage chamber.

[0039] The multiple data acquisition modules include a compressor acquisition module, a heat exchanger acquisition module, an expander acquisition module, and a gas storage chamber acquisition module. The compressor acquisition module is electrically connected to the compressor sensor, the heat exchanger acquisition module is electrically connected to the heat exchanger sensor, the expander acquisition module is electrically connected to the expander sensor, and the gas storage chamber acquisition module is electrically connected to the gas storage chamber sensor.

[0040] The sliding plates are four in number, including a compressor sliding plate, a heat exchanger sliding plate, an expander sliding plate, and a gas storage chamber sliding plate. The compressor acquisition module is located on the compressor sliding plate, the heat exchanger acquisition module is located on the heat exchanger sliding plate, the expander acquisition module is located on the expander sliding plate, and the gas storage chamber acquisition module is located on the gas storage chamber sliding plate.

[0041] Specifically, the compressor sensor and the expander sensor may each include a pressure sensor, a temperature sensor, a flow sensor, and a speed sensor, and the heat exchanger sensor and the gas storage chamber sensor may each include a pressure sensor, a temperature sensor, and a flow sensor.

[0042] This allows for the installation of sensors on the compressor, heat exchanger, expander, and air storage chamber of the compressed air energy storage system. The detection data from these sensors on different devices is then transmitted to four different data acquisition modules. Each of the four modules processes the data from its respective device, ensuring that each layer 12 corresponds to the data processing function of one device. Since the operating states of the various devices in the compressed air energy storage system differ, this facilitates the classification, processing, and centralized monitoring of the system's detection data.

[0043] Specifically, each of the sensors is equipped with an anti-interference structure, such as a shielding layer. This reduces the impact of electromagnetic interference and radio frequency interference.

[0044] More specifically, such as Figure 3 As shown, each data acquisition module includes a data acquisition unit 31 and a controller 32. The data acquisition unit 31 is adapted to collect the detection data of the sensor, and the controller 32 is adapted to process the data collected by the data acquisition unit 31. This facilitates the collection and processing of the sensor's detection data.

[0045] Advantageously, the high-efficiency data acquisition device 1 for compressed air energy storage systems also includes multiple alarm devices, each electrically connected to a plurality of the data acquisition modules. Specifically, threshold values ​​for key parameters of each device can be set in the controller 32, triggering an alarm when the threshold is reached. For example, threshold values ​​for compressor speed, pressure, temperature, and flow rate can be set in the controller 32 of the compressor acquisition module. When a parameter of the compressor reaches the threshold, the alarm device is controlled to issue an alarm. The alarm can be one or more of audible and optical alarms. This further facilitates the monitoring of the high-efficiency data acquisition device 1 for compressed air energy storage systems.

[0046] More advantageously, such as Figure 3 As shown, the high-efficiency data acquisition device 1 for the compressed air energy storage system also includes multiple power supply devices 33. These power supply devices 33 are respectively mounted on multiple sliding plates 20 and electrically connected to the multiple data acquisition modules. Specifically, the power supply devices 33 can be batteries. By setting up power supply devices 33 in each layer space 12, each layer's power supply device 33 operates independently, allowing independent power supply to the data acquisition modules within its respective layer space 12. This enables the equipment in each layer space 12 to operate independently, saving energy. Due to the operating characteristics of the compressed air energy storage system, the compressor, heat exchanger, expander, and air storage chamber may have inconsistent operating times. For example, during off-peak load periods, only the compressor, heat exchanger, and air storage chamber operate. In this case, the power supply device 33 for the expander layer can be de-energized, stopping the operation of that layer to achieve energy saving.

[0047] Figure 3 A high-efficiency data acquisition device 1 for a compressed air energy storage system according to some examples of the present invention is shown. For example... Figure 3 As shown, each layer space 12 has a guide rail 21 on its bottom wall, and the sliding plate 20 is slidably mounted on the guide rail 21. This facilitates the slidable mounting of the sliding plate 20 within the layer space 12, and the guide rail 21 can be used to position and guide the sliding plate 20, improving the stability and reliability of the sliding plate 20 during sliding.

[0048] Furthermore, each sliding plate 20 is provided with a mounting slot, on which the data acquisition module is detachably mounted. Specifically, each sliding plate 20 has three mounting slots, on which the data acquisition instrument 31, the controller 32, and the power supply device 33 are respectively mounted. This facilitates the installation and removal of the data acquisition module and further facilitates the maintenance of the high-efficiency data acquisition device 1 for the compressed air energy storage system.

[0049] Advantageously, such as Figure 3As shown, a cooling fan 13 is provided on the rear surface of each layer space 12. This allows the cooling fan 13 to dissipate heat from the layer space 12, preventing excessive temperature from affecting the accuracy of data acquisition.

[0050] Figures 1-3 A high-efficiency data acquisition device 1 for a compressed air energy storage system according to some examples of the present invention is shown. For example... Figures 1-3 As shown, the high-efficiency data acquisition device 1 for the compressed air energy storage system also includes a door 40, which is closable and can be installed on the cabinet 10. This allows the cabinet 10 to be opened or closed using the door 40, facilitating the protection of the various components inside the cabinet 10.

[0051] Advantageously, such as Figure 1 and Figure 3 As shown, the high-efficiency data acquisition device 1 for the compressed air energy storage system also includes multiple display panels 50, which are mounted on the door 40 and electrically connected to the multiple data acquisition modules. This allows the display panels 50 to display key operating parameters of the corresponding equipment in the compressed air energy storage system, facilitating operators to take individual action for each piece of equipment based on real-time parameters. For example, the display panels 50 can display parameters such as the rotational speed, pressure, and temperature of the corresponding equipment.

[0052] Other components and operations of the high-efficiency data acquisition device 1 for compressed air energy storage system according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
