Description

Technical Field

[0001] This utility model relates to the field of photovoltaic operation and maintenance technology, and in particular to a photovoltaic operation and maintenance testing instrument with positioning function. Background Technology

[0002] Photovoltaic operation and maintenance (O&M) refers to the daily and periodic maintenance, inspection, and operation management of photovoltaic power generation systems to ensure the normal and efficient operation of the system and extend its lifespan. The main tasks of photovoltaic O&M include the following aspects: daily inspection and operation management, cleaning and maintenance, fault handling and repair, safety management and environmental monitoring. Photovoltaic O&M is the guarantee for the normal operation of photovoltaic power generation systems. Through effective maintenance and management, the power generation efficiency of the system can be improved, the failure rate can be reduced, and the reliability and economy of the system can be guaranteed.

[0003] To address the shortcomings of existing photovoltaic (PV) operation and maintenance testing instruments, which require outdoor placement for environmental monitoring, most existing instruments are placed directly on the ground, making them prone to tipping over and affecting the testing process. Furthermore, the wind speed detectors on these instruments, which are crucial for wind speed measurement, are bolted in place, making quick disassembly and repair difficult if damaged.

[0004] Existing technology discloses a photovoltaic operation and maintenance testing instrument with positioning function, including: a support rod, a control cabinet, a data cable, and a wind speed detector. The control cabinet is installed on one side of the support rod, and the support rod serves as a load-bearing foundation. This photovoltaic operation and maintenance testing instrument with positioning function can rotate a threaded rod through a knob inside the positioning and placement structure via a second bevel gear and a first bevel gear, and push a push rod through a threaded hole to move. This push rod pushes a first connecting rod and unfolds the support leg, allowing the support leg to be fixed in the ground with a ground nail, thus facilitating stable placement of the equipment. Furthermore, by disassembling and repairing the rotating block inside the structure, a fixed block can be slid to a position flush with the slide groove via the second connecting rod, allowing the wind speed detector to move upward as a whole, and the fixed block to slide out along the slide groove, facilitating quick disassembly and repair of the wind speed detector.

[0005] However, as detailed in the comparative document, since this device is placed outdoors for environmental monitoring, its control cabinet, being a rigid structure, is susceptible to strong winds during windy seasons. Strong winds can easily blow onto the largest surface area of ​​the control cabinet, subjecting both the cabinet and support rods to significant forces. Over time, this can negatively impact the stable operation of the monitoring device outdoors. Therefore, it is necessary to provide a photovoltaic operation and maintenance monitoring device with positioning capabilities to address these technical issues. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a photovoltaic operation and maintenance testing instrument with positioning function, which can better ensure that the testing instrument is in a stable state and facilitate the stable operation of the testing instrument outdoors.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A photovoltaic operation and maintenance testing instrument with positioning function includes: a support rod, a control cabinet on one side of the support rod, the control cabinet being connected to the support rod via a connecting unit, a horizontal plate fixed to the top of the support rod, a detector assembly mounted on the upper surface of the horizontal plate, the detector assembly being connected to the control cabinet via a connecting line, most of the connecting line being located inside the support rod and the horizontal plate, and the connecting unit including: two horizontal bars, fixed to one side surface of the control cabinet from top to bottom; a cylinder fitted onto one side of the outer wall of the horizontal bars, with the inner wall of the cylinder fixedly connected to the outer wall of the support rod; a sliding groove formed on the other side of the outer wall of the cylinder, allowing the horizontal bars to slide back and forth within it; a collar rotatably connected to the inner wall of the cylinder; and a first spring fixed to the inner wall of the collar, with the inner ring of the first spring fixedly connected to the outer wall of the support rod; wherein, when a strong external wind blows across the largest surface area of ​​the control cabinet, the horizontal bars can slide back and forth within the sliding groove.

[0009] Preferably, the portions of the connecting wires exposed on the support rod and the cross plate are fitted with protective sleeves, and the two ends of the protective sleeves are fixedly connected to the surface of the material they are attached to.

[0010] Preferably, a take-up unit is provided inside the upper part of the support rod. The take-up unit includes: two base blocks, which are respectively fixed to the upper sides of the inner wall of the support rod; a round rod, which is fixed to the surface of the base block away from the support rod; a groove block, which is rotatably connected to the upper side of the outer wall of the round rod; a second spring, which is fixed to the inner wall of the groove block, and the inner ring of the second spring is fixedly connected to the contact surface of the round rod; and two attaching rods, which are respectively fixed to the front and rear sides between the two groove blocks, and the attaching rods are in contact with the contact surface of the connecting wire.

[0011] Preferably, the two crossbars are arranged symmetrically above and below the center point of the control cabinet.

[0012] Preferably, a through groove is provided on the upper front side of the outer wall of the support rod, and a baffle is provided in front of the through groove. Bolts are inserted at the four corners of the front surface of the baffle, and the bolts pass through the baffle and are threadedly connected to the support rod.

[0013] Preferably, a plurality of spacers are uniformly fixed between the two posts.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) This utility model, through the cooperation between the support rod, control cabinet, horizontal plate, detector assembly, connecting line and connecting unit, installs the bottom end of the support rod to a suitable position in the outside. The operator then supplies power to the electronic components inside the control cabinet and the detector assembly to make them run. When encountering strong winds, the wind is likely to blow towards the surface of the largest area of ​​the control cabinet. The horizontal rod can slide inside the slide groove, allowing the control cabinet to revolve around the collar at a certain angle. The surface of the largest area of ​​the control cabinet will be closer to the direction of the strong wind flow, thereby reducing the force of the airflow on the control cabinet and support rod during the strong wind season, which is conducive to the stable operation of the detector device outdoors.

[0016] (2) Through the cooperation between the support rod, control cabinet, horizontal plate, detector assembly, connecting line, connecting unit and winding unit, the second spring is in a state of compression deformation. The two sticks can wind up the connecting line between them, so that the connecting line can be neatly set inside the support rod, so as to make quick judgment when the equipment fails due to short circuit of the connecting line.

[0017] (3) This utility model uses the cooperation between the support rod, the horizontal plate, the connecting line and the protective tube. The connecting line is located inside the support rod, the horizontal plate and the protective tube, which can prevent external ultraviolet rays and other factors from affecting it, and facilitates the improvement of the overall circuit stability of the device.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0026] Example 1:

[0027] like Figure 1-6 As shown, this utility model provides a photovoltaic operation and maintenance testing instrument with positioning function, comprising: a support rod 1, the bottom end of which is equipped with a base for fixed installation on a base surface. The installation structure of the support rod 1 is well-established and therefore not described again in this application. A control cabinet 2 is provided on one side of the support rod 1. The control cabinet 2 contains electronic components required for the operation of the photovoltaic operation and maintenance testing instrument, which are electrically connected to a detector assembly 4 via a connecting cable 5. The detector assembly 4 is a detector structural component required for the operation of the photovoltaic operation and maintenance testing instrument. When the instrument is powered on, the various electronic components inside the control cabinet 2 and the detector assembly 4 are activated to perform photovoltaic operation and maintenance testing. The control cabinet 2 is connected to the support rod 1 via a connecting unit. A horizontal plate 3 is fixed to the top of the support rod 1, and the detector assembly 4 is installed on the upper surface of the horizontal plate 3. The detector assembly 4 is connected to the support rod 1 via a connecting unit. Wiring 5 is connected to control cabinet 2. Most of the wiring 5 is located inside support rod 1 and cross plate 3. The connection unit includes: cross rod 6, two of which are fixed to one side surface of control cabinet 2 from top to bottom; cylinder 7, which is fitted on one side of the outer wall of cross rod 6, and the inner wall of cylinder 7 is fixedly connected to the outer wall of support rod 1; slide groove 8, which is opened on the other side of the outer wall of cylinder 7, and slide groove 8 allows cross rod 6 to slide in the back-and-forth direction inside it; collar 9, which is rotatably connected to the inner wall of cylinder 7; collar 9 is rotatably connected to cylinder 7 through dustproof bearing; first spring 10, which is fixed to the inner wall of collar 9, the coefficient of first spring 10 is 10-50 N / CM, and the inner ring of first spring 10 is fixedly connected to the outer wall of support rod 1; wherein, when a strong wind blows on the surface of the control cabinet 2 with the largest area, cross rod 6 can slide in the back-and-forth direction inside slide groove 8.

[0028] Example 2:

[0029] The exposed portions of the connecting wire 5 on the support rod 1 and the cross plate 3 are fitted with protective sleeves 19, and the two ends of the protective sleeves 19 are fixedly connected to the surface of the material they are attached to. The protective sleeves 19 can protect the connecting wire 5 exposed on the outside of the support rod 1 and the cross plate 3, preventing the connecting wire 5 from being exposed to strong ultraviolet rays and thus promoting long-term use.

[0030] Example 3:

[0031] The support rod 1 has a take-up unit located on its upper interior. The take-up unit includes: two base blocks 11, which are fixedly attached to the upper sides of the inner wall of the support rod 1; a round rod 12, which is fixedly attached to the surface of the base block 11 away from the support rod 1; a groove block 13, which is rotatably connected to the upper outer wall of the round rod 12, and the round rod 12 is rotatably connected to the groove block 13 through a dustproof bearing; a second spring 14, which is fixedly attached to the inner wall of the groove block 13, and the inner ring of the second spring 14 is fixedly connected to the contact surface of the round rod 12, and the coefficient of the second spring 14 is 5-10 N / CN; and two connecting rods 15, which are fixedly attached to the front and rear sides between the two groove blocks 13, and the connecting rods 15 are in contact with the contact surface of the connecting wire 5.

[0032] Example 4:

[0033] The two crossbars 6 are symmetrically arranged above and below the center point of the control cabinet 2, which allows the two crossbars 6 to exert force on the control cabinet 2 evenly.

[0034] Example 5:

[0035] A through groove 17 is provided on the upper front side of the outer wall of the support rod 1. A baffle 16 is provided in front of the through groove 17. Bolts 18 are inserted at the four corners of the front surface of the baffle 16. The bolts 18 pass through the baffle 16 and are threadedly connected to the support rod 1. The baffle 16 can be disassembled by rotating the bolts 18 counterclockwise. The first unit can be installed and maintained through the through groove 17, which facilitates the operation of the operator.

[0036] Example 6:

[0037] Multiple spacers 20 are evenly fixed between the two support rods 15. The spacers 20 facilitate the separation of the multiple connecting lines 5 inside the support rod 1.

[0038] In use, first, after installing the bottom end of the support rod 1 to a suitable external position, the operator supplies power to the electronic components inside the control cabinet 2 and the detector assembly 4 to enable its operation. During windy seasons, when strong winds tend to blow towards the largest surface area of ​​the control cabinet 2, the crossbar 6 can slide inside the slide groove 8, allowing the control cabinet 2 to revolve around the collar 9 at a certain angle. The largest surface area of ​​the control cabinet 2 will then face the direction of the strong wind flow, thereby reducing the force of the airflow on the control cabinet 2 and support rod 1 during windy seasons, facilitating stable outdoor operation of the detector. During this process, the first spring 10 undergoes compression deformation, enabling... To prevent sudden and rapid movement of the control cabinet 2, damage to the internal electronic components of the control cabinet 2 can be prevented due to violent movement. When the strong wind subsides, the second spring 14 returns to its compressed and deformed state, which can retract the part of the connecting wire 5 that extends out of the support rod 1. The two connecting rods 15 can rewind the connecting wire 5 between them, so that the connecting wire 5 is neatly arranged inside the support rod 1, which facilitates quick judgment when equipment failure is caused by short circuit of the connecting wire 5. In addition, the connecting wire is located inside the support rod, the cross plate and the protective cylinder, which can prevent the external ultraviolet rays and other factors from affecting it, and facilitates the improvement of the overall circuit stability of the device.

[0039] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
