Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically a solar power supply control and protection device for a sewage treatment system. Background Technology

[0002] In rural wastewater treatment environmental protection facilities, the aeration equipment typically uses AC mains power. This method has significant drawbacks: it wastes power and makes obtaining power sources difficult. Therefore, solar power generation equipment has been introduced to rural areas. Currently, solar power generation equipment mainly consists of arranged solar panels, inverters, and batteries. The electricity generated by each solar panel is processed by the inverter and stored in the battery.

[0003] In existing rural solar power generation systems, photovoltaic (PV) panels are connected in parallel, and the energy is processed by an inverter before being stored in a battery. However, this method is prone to problems where insufficient voltage from one or more PV panels due to shading or damage can damage the entire system. To address this, an intelligent control module has been introduced. This module monitors the output voltage of each PV panel. When the output voltage is too low, it disconnects the circuit between that panel and the inverter, allowing the other panels to continue operating normally. The problematic panel can then be repaired.

[0004] However, the above-mentioned existing technologies still have shortcomings in use: photovoltaic panels are usually fixed to their respective support frames by bolts. When the photovoltaic panels are damaged, there is a problem of poor disassembly, which increases the workload of later maintenance.

[0005] Therefore, this utility model provides a solar power supply control and protection device for a sewage treatment system. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a solar power supply control and protection device for a sewage treatment system to solve the problems mentioned in the background. This utility model not only meets the function of protecting the entire power generation equipment, but also has the advantage of making it easier to disassemble damaged photovoltaic modules, thus improving the convenience of maintenance and replacement.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a solar power supply control and protection device for a sewage treatment system, comprising an analog controller, a voltage acquisition module, and several rows of unit support frames. A photovoltaic panel assembly is detachably connected within each unit support frame. The voltage acquisition module is located on one side of each unit support frame. A drive group is mounted on each unit support frame below the photovoltaic panel assembly. Limiting members are located on both sides of the photovoltaic panel assembly within each unit support frame. The drive group includes a drive shaft that is perpendicular to the back of the photovoltaic panel assembly and can be raised and lowered. The drive shaft is fixedly connected to the bottom of the limiting members via a connecting frame.

[0008] Furthermore, a grooved support plate is fixedly connected to the lower end face of the unit support frame, and a rectangular pad near the bottom is fixedly connected to the inner side of the unit support frame. The voltage acquisition module and the drive group are both located on one side of the grooved support plate.

[0009] Furthermore, the connecting frame includes a crossbeam and connecting plates located at both ends of the crossbeam. The top of the connecting plate passes through one side of the rectangular pad and the two are slidably engaged. The limiting member has a T-shaped cross section and the middle part of the bottom of the middle plate on it is fixedly connected to the top of the connecting plate.

[0010] Furthermore, the lower end face of the limiting member is bonded with rubber pads located on both sides of the middle plate.

[0011] Furthermore, a guide sleeve fitted onto the outside of the connecting plate is welded to the bottom of the rectangular pad.

[0012] Furthermore, the drive assembly includes a control motor and a lead screw. The control motor is fixedly mounted on one side of the slotted support plate and its output shaft is fixedly connected to one end of the lead screw. The top of the drive shaft is fixedly connected to the middle of the lower end face of the crossbeam, and the bottom of the drive shaft has a threaded hole that engages with the lead screw.

[0013] Furthermore, the control motor and the analog controller are electrically connected.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, a limiting member is provided between the support frame and the photovoltaic panel assembly. A drive shaft located below the limiting member is provided inside the support frame. The drive shaft has the function of moving up and down. Then, a connecting frame is connected to the top of the drive shaft. The connecting frame and the bottom of the limiting member are fixedly connected. When the drive shaft is controlled to move upward, the limiting member will move upward and away from the photovoltaic panel assembly. At this time, the photovoltaic panel assembly is released from the limiting, so it can be directly removed from the support frame. This has the advantage of making it more convenient to inspect, maintain and replace damaged solar panels.

[0016] 2. In this utility model, a voltage acquisition module and an analog controller are provided. The drive group includes a control motor, and the control motor and the analog controller are electrically connected. Thus, when a photovoltaic panel is damaged and the power is cut off, the corresponding control motor below it is started by the analog controller, and then the drive shaft is raised by the lead screw. Therefore, it has the advantage of automatically controlling and unlocking the damaged photovoltaic panel, and the degree of automation is higher. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a solar power supply control and protection device for a sewage treatment system, including an analog controller 4, a voltage acquisition module 3, and several rows of unit support frames 1. In use, several unit support frames 1 are fixedly installed in a bearing frame. A photovoltaic panel assembly 2 is detachably connected inside the unit support frame 1. Each unit support frame 1 is equipped with a photovoltaic panel assembly 2. The photovoltaic panel assembly 2 includes a photovoltaic panel and a protective frame sleeved on the outside of the photovoltaic panel. The specific connection method is prior art and will not be described in detail in this application.

[0024] The voltage acquisition module 3 corresponds one-to-one with the photovoltaic panel assembly 2. It includes a PLC analog input module, a DC voltage transmitter module, and diodes, etc. Its function is to collect the output voltage signal of the photovoltaic panel on the photovoltaic panel assembly 2 via the DC voltage transmitter module. When the signal is abnormal, it transmits the abnormal signal to the PLC analog input module, which then transmits the abnormal signal to the analog controller 4. The analog controller 4 uses a PLC-controlled structure and controls the circuit breaker connecting the photovoltaic panel and the inverter to open, thus disconnecting the current charging circuit of the photovoltaic panel. Since this part of the structure is existing technology, its specific wiring connection method will not be described in detail in this application. This technical solution is an improvement on the shortcomings of existing solar power generation equipment with intelligent disconnection function for photovoltaic panel charging circuits.

[0025] In this technical solution, the voltage acquisition module 3 is set on one side inside the unit support frame 1 to acquire the voltage output of each photovoltaic panel 2. Limiting members 6 are set on both sides of the photovoltaic panel 2 inside the unit support frame 1. A drive group 5 is set on the unit support frame 1 below the photovoltaic panel 2. The drive group 5 includes a drive shaft 51 that is perpendicular to the back of the photovoltaic panel 2 and can be raised and lowered. The drive group 5 provides driving force for the raising and lowering movement of the drive shaft 51. The drive shaft 51 is fixedly connected to the bottom of the limiting member 6 through the connecting frame 7. When the drive shaft 51 moves up and down, it can drive the limiting member 6 to move up and down through the connecting frame 7. When the limiting member 6 moves downward, it can squeeze the photovoltaic panel 2 into the unit support frame 1. Conversely, it releases the restriction on the photovoltaic panel 2. At this time, the photovoltaic panel 2 can be easily taken out of the support frame 1.

[0026] Specifically, a slotted support plate 11 is fixedly connected to the lower end face of the unit support frame 1, and a rectangular pad 12 near the bottom is fixedly connected to the inner side of the unit support frame 1. The voltage acquisition module 3 and the drive group 5 are both set on one side of the slotted support plate 11, that is, the voltage acquisition module 3 and the drive group 5 are integrated and installed under each unit support frame 1.

[0027] Furthermore, the connecting frame 7 includes a crossbeam 71 and connecting plates 72 located at both ends of the crossbeam 71. The top of the connecting plate 72 passes through one side of the rectangular pad 12 and the two are slidably engaged. In a preferred embodiment, a guide sleeve 121 sleeved on the outside of the connecting plate 72 is welded to the bottom of the rectangular pad 12. The limiting member 6 has a T-shaped cross section, and the middle part of the bottom of the middle plate 61 on it is fixedly connected to the top of the connecting plate 72. When the limiting member 6 moves up and down, it can drive the middle plate 61 to enter and exit the gap formed by the two sides of the photovoltaic panel module 2 and the two sides inside the unit support frame 1. The horizontal plate at the top of the limiting member 6 presses the upper end surface of the photovoltaic panel module 2 near the two sides, and at the same time presses the upper end surface of the unit support frame 1 near the two sides.

[0028] In this embodiment, rubber pads 8 located on both sides of the middle plate 61 are bonded to the lower end face of the limiting member 6. The rubber pads 8 serve to buffer and protect the photovoltaic panel assembly 2.

[0029] In this embodiment, the drive assembly 5 includes a control motor 52 and a lead screw 53. The control motor 52 is fixedly mounted on one side of the slotted support plate 11, and its output shaft is fixedly connected to one end of the lead screw 53. The top of the drive shaft 51 is fixedly connected to the middle of the lower end face of the crossbeam 71. The bottom of the drive shaft 51 has a threaded hole 511 that engages with the lead screw 53. The control motor 52 provides driving force to the rotation of the lead screw 53, and then the drive shaft 51 is driven to rise and fall by the engagement. The control motor 52 is electrically connected to the analog controller 4. That is, when the analog controller 4 controls the photovoltaic panel on the current photovoltaic panel assembly 2 to be de-energized, it simultaneously controls the limiting member 6 above the photovoltaic panel assembly to move upward, thereby releasing the restriction on the photovoltaic panel assembly 2 and facilitating the inspection, maintenance, and replacement of the photovoltaic panel assembly 2.

[0030] Working principle: When one of the photovoltaic panel components 2 experiences a low power generation voltage, the voltage acquisition module 3 acquires the voltage signal of the photovoltaic panel component 2. The analog controller 4 controls the output voltage circuit of the photovoltaic panel component 2 to disconnect, and at the same time starts the control motor 52, the lead screw 53 rotates, the drive shaft 51 rises, the connecting frame 7 rises, and the limiting piece 6 moves upward away from the unit support frame 1 and the photovoltaic panel component 2. At this time, the photovoltaic panel component 2 is released from restriction, and maintenance personnel can easily remove the photovoltaic panel component 2 from the unit support frame 1.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
