Description

Technical Field

[0001] This utility model relates to the field of data acquisition technology, specifically a data acquisition device based on a distributed photovoltaic power station. Background Technology

[0002] A data acquisition unit (DAU) for a distributed photovoltaic (PV) power station is a key device used to collect, process, and transmit various data from the PV power station. Through its internal sensors and data acquisition circuits, it connects to various devices within the PV power station. For analog data, such as voltage and current, an analog-to-digital converter (ADC) transforms the analog signals into digital signals; for digital data, such as device status signals, it reads the data directly.

[0003] Most existing photovoltaic data acquisition devices are fixed with screws or bolts (mainly to the wall) and electrically connected to each other via connecting cables (network cables, data cables, power cables, etc.). In actual use, in order to ensure the convenience of connecting between devices, the connecting cables are usually quite long. However, after the connecting cables are connected, the excess wires are bent and loose, making them susceptible to accidental bumps or pulling from external factors, which affects the connection stability between the connecting cables and the photovoltaic data acquisition devices.

[0004] Therefore, there is an urgent need for data acquisition devices based on distributed photovoltaic power plants to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a data acquisition device based on a distributed photovoltaic power station, comprising a body and multiple connection ports disposed on the body, and further comprising a storage component disposed on the body for storing and protecting excess connection cables;

[0006] The storage assembly includes a fixing plate disposed on the side of the body near each connection port. The fixing plate is connected to the body via a fixing component. Multiple storage cylinders are fixedly connected to the side of the fixing plate away from the body. Each storage cylinder is matched with a connection port. Each storage cylinder is slidably connected to a storage rod. A first storage plate and a second storage plate are fixedly connected to the side wall of each storage rod. Each storage cylinder is provided with a guide component for guiding the movement of the first storage plate.

[0007] Each of the storage tubes has a pull plate on the side away from the fixed plate, and one side of the pull plate is connected to the storage rod.

[0008] The guide assembly includes two symmetrically arranged guide grooves on the side wall of the storage tube. The two guide grooves are arranged through the storage tube on the side near the fixed plate. The two guide grooves are connected to guide plates through a telescopic assembly. The opposite ends of the two guide plates are connected to the first storage plate.

[0009] The telescopic assembly includes a telescopic rod fixedly connected to the bottom wall of the guide groove, a guide plate slidably connected to the telescopic rod, and a spring sleeved on the side wall of the telescopic rod, with the two ends of the spring connected to the guide plate and the fixed plate respectively.

[0010] Each of the aforementioned storage tubes has a wire-holding groove on the side near the pull plate.

[0011] The fixing component includes two bolts inserted into the fixing plate, and the outer shell of the machine body near the bolts has two threaded holes, which are matched with the bolts.

Detailed Implementation

[0018] 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.

[0019] Example 1

[0020] Please see Figures 1-3The data acquisition device based on the distributed photovoltaic power station shown in the figure includes a body 101 and multiple connection ports 102 disposed on the body 101, and also includes a storage component disposed on the body 101 for storing and protecting excess connection cables.

[0021] The storage assembly includes a fixing plate 201 disposed on the side of the body 101 near each connection port 102. The fixing plate 201 is connected to the body 101 through the fixing assembly. Multiple storage cylinders 202 are fixedly connected to the side of the fixing plate 201 away from the body 101. Each storage cylinder 202 is matched with the connection port 102. Each storage cylinder 202 is slidably connected to a storage rod 203. A first storage plate 204 and a second storage plate 205 are fixedly connected to the side wall of each storage rod 203. Each storage cylinder 202 is provided with a guide assembly for guiding the movement of the first storage plate 204.

[0022] It should be noted that the storage component, in conjunction with the guide and telescopic components, effectively stores and protects excess connecting wires, thereby reducing the risk of accidental contact or pulling of the connecting wires due to external factors and improving the connection stability between the connecting wires and the photovoltaic data acquisition unit.

[0023] It is worth noting that the specific structure and working principle of photovoltaic data acquisition devices are already known to those in the field, and will not be elaborated upon here.

[0024] Please see Figure 2 and Figure 3 In the diagram, each storage tube 202 has a pull plate 206 on the side away from the fixed plate 201, and one side of the pull plate 206 is connected to the storage rod 203.

[0025] It should be noted that the pull plate 206 is designed to facilitate pulling the storage rod 203 and to limit the position of the connected wire after storage.

[0026] Please see Figure 2 and Figure 3 The guide assembly shown in the figure includes two symmetrically arranged guide grooves 301 on the side wall of the storage tube 202. The two guide grooves 301 are arranged through the storage tube 202 on the side near the fixed plate 201. The two guide grooves 301 are connected to guide plates 302 through telescopic components. The opposite ends of the two guide plates 302 are connected to the first storage plate 204.

[0027] It should be noted here that the guide component is used to guide and limit the movement of the first storage plate 204.

[0028] Please see Figure 2 and Figure 3The telescopic assembly shown in the figure includes a telescopic rod 401 fixedly connected to the bottom wall of the guide groove 301, a guide plate 302 slidably connected to the telescopic rod 401, and a spring 402 sleeved on the side wall of the telescopic rod 401. The two ends of the spring 402 are respectively connected to the guide plate 302 and the fixed plate 201.

[0029] It should be noted here that the telescopic component is used to provide a reset function for the storage rod 203 and to ensure that the pull plate 206 abuts against the end face of the storage tube 202, thereby limiting the position of the connected wire after storage.

[0030] Please see Figure 2 and Figure 3 Each storage tube 202 in the diagram has a wire-holding groove 5 on the side near the pull plate 206;

[0031] It should be noted here that the wire slot 5 is used to guide the side wall of the wound connecting wire out from inside the storage tube 202, thereby fixing the stored connection.

[0032] Working principle: When using this data acquisition device, first fix the body 101 to the place of use, and then use the fixing components to install the fixing plate 201 onto the body 101. After the body 101 is fixed, the electrical connection between devices can be made through the connecting cables (network cable, data cable, power cable, etc.). After the connection is completed, if some connecting cables become loose due to their length, the first storage plate 204 and the second storage plate 205 on the side wall of the storage rod 203 can be moved out of the storage tube 202 by pulling the pull plate 206.

[0033] When the first storage plate 204 and the second storage plate 205 are removed from the storage tube 202, the excess connecting wires can be wound around the side wall of the storage rod 203 located between the first storage plate 204 and the second storage plate 205. After the excess connecting wires are wound around the side wall of the storage rod 203, the pull plate 206 can be released. At this time, under the elastic action of the telescopic component, the first storage plate 204 and the second storage plate 205 will be retracted into the storage tube 202, thereby retracting the connecting wires wound around the side wall of the storage rod 203 into the storage tube 202. This achieves the storage and protection of excess connecting wires, reduces the risk of accidental contact or pulling by external factors, and improves the connection stability between the connecting wires and the photovoltaic data acquisition device.

[0034] After establishing an electrical connection between the photovoltaic data acquisition device and the equipment using a connecting cable, it can then connect to various devices in the photovoltaic power station via its internal sensors and data acquisition circuits. For analog data, such as voltage and current, an analog-to-digital converter (ADC) transforms the analog signals into digital signals. For digital data, such as equipment status signals, the data is read directly. The acquired data is processed and analyzed by a processor, encapsulated according to a specific communication protocol, and then transmitted through the corresponding communication module. At the receiving end, the monitoring system or host computer parses the data according to the same communication protocol, reconstructing the original data for display, storage, and further analysis.

[0035] Example 2

[0036] Please see Figure 1 This embodiment further illustrates Example 1. The fixing component shown in the figure includes two bolts 6 inserted into the fixing plate 201. The outer shell of the body 101 near the bolts 6 has two threaded holes, which are matched with the bolts 6.

[0037] It should be noted that: by setting up the fixing component, the fixing plate 201 is installed to the outer shell of the body 101 through the threaded connection between the bolt 6 and the threaded hole, which facilitates the storage and protection of the connecting wire, and the detachable connection provides convenience for the installation and use of the storage component.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
