Technical Field

[0001] The utility model relates to a solar charge and discharge controller, in particular to an intelligent MPPT solar charge and discharge controller, belonging to the technical field of solar controllers. Background Art

[0002] MPPT controller, or maximum power point tracking solar controller, is an upgraded product of the traditional solar charge and discharge controller. It is used in solar photovoltaic systems and can detect the power generation voltage of solar panels in real time and track the highest voltage and current values, coordinate the work of solar panels, batteries, and loads, and enable the system to output at maximum power.

[0003] At present, when installing the solar MPPT charge and discharge controller, it is mainly fixed by drilling holes and installing bolts. This fixing method may not only damage the controller during the drilling process, but also is cumbersome to operate and inconvenient to disassemble. When the controller fails, it cannot be quickly disassembled for maintenance. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides an intelligent MPPT solar charge and discharge controller, which, through the setting of a fixed structure, replaces the method of drilling holes for transmission bolts to fix the charge and discharge controller body as a whole on the mounting plate, thereby simplifying the tedious steps of installation and disassembly, and facilitating rapid disassembly and maintenance when a fault occurs in the charge and discharge controller body.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] An intelligent MPPT solar charge and discharge controller comprises a charge and discharge controller body and a mounting plate, wherein the mounting plate is provided with a fixing structure, wherein the fixing structure comprises two fixing plates symmetrically fixedly mounted on the surface of the mounting plate, a screw ring is movably mounted between the two fixing plates, a plurality of shifting blocks are evenly fixedly mounted on the surface of the screw ring, and a threaded rod used in conjunction with the shifting blocks is fixedly mounted on the back of the charge and discharge controller body.

[0007] Furthermore, two positioning rods are symmetrically fixedly installed on the upper part of the charge and discharge controller body, and two positioning cylinders are symmetrically fixedly installed on the front side of the mounting plate.

[0008] Furthermore, a protective shell is fixedly installed on the bottom of the charge and discharge controller body, and a plurality of baffles are slidably installed on the bottom of the protective shell.

[0009] Furthermore, a limit frame is fixedly installed on the front side of the protective shell, and a wedge is fixedly installed on one end of the baffle.

[0010] Furthermore, one end of the positioning rod is configured to be conical, and the size of the wedge block matches the size of the inner space of the limiting frame.

[0011] Furthermore, heat dissipation openings are provided on both sides of the charge and discharge controller body, and a heat dissipation fan is fixedly installed on the top of the charge and discharge controller body.

[0012] Furthermore, a dustproof net is fixedly installed inside the heat dissipation port.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] By setting a fixed structure, the charge and discharge controller body is fixedly installed on the mounting plate as a whole in a way that replaces the method of drilling holes for transmission bolts. When installing the charge and discharge controller body, the threaded rod on the back is docked on the screw ring, and then the multiple shifting blocks on the screw ring are turned to make the screw ring rotate between the two fixed plates. After the screw ring is rotated, it can be threadedly connected with the threaded rod, so that the charge and discharge controller body is fixedly installed on the mounting plate as a whole; and when the charge and discharge controller body fails, the screw ring can be separated from the threaded rod by rotating it in the reverse direction, thereby completing the disassembly of the charge and discharge controller body, simplifying the tedious steps of installation and disassembly, and facilitating rapid disassembly and maintenance when the charge and discharge controller body fails.

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figure 1-4As shown, an intelligent MPPT solar charge and discharge controller includes a charge and discharge controller body 1 and a mounting plate 2, a fixing structure 3 is arranged on the mounting plate 2, the fixing structure 3 includes two fixing plates 4 symmetrically fixedly installed on the surface of the mounting plate 2, a screw ring 5 is movably installed between the two fixing plates 4, a plurality of shifting blocks 6 are evenly fixedly installed on the surface of the screw ring 5, and a threaded rod 7 used in conjunction with the shifting blocks 6 is fixedly installed on the back of the charge and discharge controller body 1. By setting the fixing structure 3, the charging and discharging controller body 1 can be fixedly installed on the mounting plate 2 as a whole instead of the transmission bolt drilling method. When installing the charging and discharging controller body 1, the threaded rod 7 on the back thereof is docked on the screw ring 5, and then the multiple shifting blocks 6 on the screw ring 5 are moved to make the screw ring 5 rotate between the two fixing plates 4. After the screw ring 5 is rotated, it can be threadedly connected with the threaded rod 7 to fix the charging and discharging controller body 1 as a whole on the mounting plate 2; and when the charging and discharging controller body 1 fails, the screw ring 5 can be rotated in the reverse direction to separate it from the threaded rod 7, thereby completing the disassembly of the charging and discharging controller body 1, simplifying the tedious steps of installation and disassembly, and facilitating the rapid disassembly and maintenance of the charging and discharging controller body 1 when a failure occurs.

[0022] like Figure 1-4 As shown, two positioning rods 8 are symmetrically fixedly installed on the upper part of the charge and discharge controller body 1, and two positioning cylinders 9 are symmetrically fixedly installed on the front side of the mounting plate 2; a protective shell 10 is fixedly installed on the bottom of the charge and discharge controller body 1, and a plurality of baffles 11 are slidably installed on the bottom of the protective shell 10; a limiting frame 12 is fixedly installed on the front side of the protective shell 10, and a wedge block 13 is fixedly installed on one end of the baffle 11. The setting of the positioning rod 8 and the positioning cylinder 9 can play a positioning function when the charge and discharge controller body 1 is installed, so that the charge and discharge controller body 1 remains balanced and stable during installation to avoid skewing; the baffle 11 is set at the bottom of the charge and discharge controller body 1 to seal and protect the wiring terminals at the bottom of the charge and discharge controller body 1 to avoid being affected by water and dust. At the same time, multiple sliding baffles 11 are set, which can open the corresponding wiring positions according to the wiring usage requirements to protect other unconnected wiring terminals; through the setting of the limit frame 12 and the wedge block 13, when the baffle 11 is closed, the wedge block 13 at one end is inserted into the limit frame 12, and the limit frame 12 and the wedge block 13 can be combined to fix the baffle 11 to prevent it from loosening.

[0023] like Figure 1-Figure 4As shown, one end of the positioning rod 8 is set to be conical, and the size of the wedge block 13 is consistent with the size of the internal space of the limit frame 12; heat dissipation ports 14 are provided on both sides of the charge and discharge controller body 1, a heat dissipation fan 15 is fixedly installed on the top of the charge and discharge controller body 1, and a dustproof net 16 is fixedly installed inside the heat dissipation port 14. By setting one end of the positioning rod 8 to be conical and making the diameter of one end smaller, the positioning rod 8 as a whole can be more easily inserted into the positioning tube 9 during installation; and the size of the wedge block 13 is designed to be consistent with the inside of the limit frame 12, which can improve the tightness of the connection between the wedge block 13 and the limit frame 12 and improve the limiting effect of the baffle 11; by setting the heat dissipation port 14 and the heat dissipation fan 15, the gas flow rate inside the charge and discharge controller body 1 can be accelerated to improve the heat dissipation effect; the setting of the dustproof net 16 can prevent dust from entering the inside of the charge and discharge controller body 1 from the heat dissipation port 14.

[0024] The working process of an intelligent MPPT solar charge and discharge controller provided in this embodiment is as follows:

[0025] When installing the charge and discharge controller body 1, the threaded rod 7 on its back is docked with the screw ring 5, and then the multiple shifting blocks 6 on the screw ring 5 are moved to rotate the screw ring 5 between the two fixed plates 4. After the rotation, the screw ring 5 can be threadedly connected with the threaded rod 7 to fix the charge and discharge controller body 1 as a whole on the mounting plate 2; when the charge and discharge controller body 1 fails, the screw ring 5 can be rotated in the opposite direction to separate it from the threaded rod 7, thereby completing the disassembly of the charge and discharge controller body 1.
