Description

Technical Field

[0001] The invention relates to the technical field of MPPT controllers, in particular to a solar water pump MPPT controller. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. In the process of photovoltaic power generation, MPPT solar controllers need to be used for control. The full name of MPPT solar controllers is "maximum power point tracking" solar controllers. It is an upgraded product of traditional solar charge and discharge controllers. MPPT controllers can detect the power generation voltage of solar panels in real time and track the highest voltage and current values, so that the system can charge the battery with maximum power output. It is used in solar photovoltaic systems to coordinate the work of solar panels, batteries, and loads, and is the brain of the photovoltaic system.

[0003] However, when fixing the MPPT controller on a wall or device, multiple connecting wires need to be installed on the wiring block inside the controller. Before installation, the protective cover needs to be removed from the controller before the screws on the wiring block can be turned, thereby reducing the installation efficiency of the connecting wires. In addition, the controller usually does not have a component to limit the connecting wires. During the installation of the connecting wires, multiple connecting wires are placed together, which is not conducive to the operator to distinguish and may easily cause the connecting wires to be installed incorrectly. When the connecting wires are pulled by external force, they may fall off from the wiring port, thereby affecting the normal use of the controller. Summary of the invention

[0030] Specifically, Figure 3 , Figure 4 , Figure 8 , Fig.11 and Fig.12As shown, the wire pressing mechanism 6 includes a slide groove 601 and a slider 602. The fixed plate 5 is equidistantly provided with a plurality of slide grooves 601. The slide groove 601 is slidably installed with a slider 602.

A pad 603 is fixedly connected to the fixed plate 5. A ball 607 is rotatably installed on the fixed plate 5. The slider 602 is arranged in an L-shaped structure. The slider 602 and the connecting rod 608 are both slidably connected to the fixed plate 5, the ball 607 is rollingly connected to the connecting rod 608, the end of the connecting rod 608 is arranged in an arc surface structure, the rubber pad 605 is arranged in an arc surface structure, and the contact part of the pressure block 604 and the rubber pad 605 is also arranged in an arc surface structure. Push the wire pressing mechanism 6 upward to make it slide inside the fixed plate 5, so as to facilitate the insertion of the connecting wire into the fixed plate 5 and the wire clamping plate 7. Loosen the wire pressing mechanism 6 to limit the connecting wire, so as to prevent the connecting wire from falling off during use. That is, when installing the connecting wire on the controller body 1, multiple connecting wires can be first connected. The line areas are separated. Before installing them one by one, push the slider 602 set on the fixing plate 5 upward by hand. Since the fixing plate 5 is installed on the cover plate 301, when the slider 602 slides in the slide groove 601 provided in the fixing plate 5, the end of the slider 602 can drive the connecting rod 608 to slide. The fixed plate 5 is rotatably installed with a ball 607 near the connecting rod 608. When the connecting rod 608 slides, the ball 607 is driven to rotate, thereby facilitating the improvement of the sliding effect of the connecting rod 608. The connecting rod 608 is fixedly connected to the pressure block 604. When the connecting rod 608 drives the pressure block 604 to slide into the inside of the fixing plate 5, the end of the pressure block 604 can squeeze the compression spring 606 sleeved on the connecting rod 608.

[0031] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7and Fig. 9 As shown, the flip mechanism 3 includes a cover plate 301 and a connecting shaft 306, the controller body 1 is rotatably connected with the connecting shaft 306, the connecting shaft 306 is fixedly installed with the cover plate 301, the cover plate 301 is fixedly connected with a limiting block 302, the controller body 1 is provided with a limiting groove 304, the limiting block 302 is fixedly connected to the controller body 1 through a rotating rod 303, the cover plate 301 is fixedly installed with a wiring block 305, the two limiting blocks 302 and the limiting grooves 304 are symmetrically arranged, the limiting blocks 302 are clamped and installed in the limiting grooves 304, the cover plate 301 is rotatably connected to the controller body 1, the fixing plate 5 and the wire clamping plate 7 are fixedly connected to the cover plate 301, and the rotating rod 303 is threadedly connected to the controller body 1.

[0032] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 and Fig.10As shown, the sliding mechanism 4 includes a shift block 401 and a slide plate 402, the cover plate 301 is slidably connected with the slide plate 402, the slide plate 402 is fixedly installed with the shift block 401, the cover plate 301 is fixedly connected with a slide bar 403, the slide bar 403 is sleeved with a telescopic spring 404, and a plurality of the shift blocks 401 are equidistantly installed at the top of the slide plate 402, the slide plate 402 is slidably connected with the slide bar 403, and the sliding mechanism 4 is pushed to facilitate the installation of the connecting line into the flip mechanism 3. The flip mechanism 3 can be rotated along the controller body 1 by using a tool, so that the connecting line of the controller body 1 can be installed without disassembling the flip mechanism 3, that is, since the connecting shaft 306 fixed on the cover plate 301 rotates in the controller body 1, when the inside of the controller body 1 needs to be repaired, the rotating rod 303 fixed in the controller body 1 is removed by using a tool, and the cover plate 301 is rotated. , it can drive the two limit blocks 302 fixed on both sides to rotate out from the limit groove 304 provided in the controller body 1, and the cover plate 301 drives the connecting shaft 306 to rotate, so that the end of the controller body 1 is in an open state, which is convenient for the internal maintenance; when the end of the connecting line is installed in the wiring block 305 fixed on the cover plate 301, the shifting block 401 is pushed, which can drive the slide plate 402 to slide into the cover plate 301. Since a slide bar 403 is fixed in the cover plate 301, when the slide plate 402 slides along the slide bar 403, the telescopic spring 404 sleeved on the slide bar 403 can be squeezed. When the slide plate 402 slides to the state where the shifting block 401 and the cover plate 301 are in conflict, it is convenient for the operator to insert the screwdriver into the wiring block 305, which is convenient for rotating the screws on the wiring block 305, so that the connecting line and the wiring block 305 can be connected without removing the cover plate 301.

[0033] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the mounting mechanism 2 includes a fixing frame 201, a mounting hole 202 and a fixing bolt 203. Two fixing frames 201 are symmetrically fixedly mounted on the controller body 1. The fixing frame 201 is provided with a mounting hole 202. The fixing bolt 203 is threadedly mounted at the mounting hole 202. The fixing frame 201 is provided with a mounting groove 204. The positioning rod 205 is threadedly mounted at the mounting groove 204. The controller body 1 can be fixed to a wall or device through the mounting mechanism 2, so that the operator can disassemble and assemble the controller body 1 during use. That is, when installing the controller body 1, a hole can be drilled on the wall or device first, and the controller body 1 can be fixed to the wall or device first. Two fixing brackets 201 are symmetrically installed on one side of the main body 1. The two installation grooves 204 on the fixing bracket 201 are aligned with the drilled holes, and then the positioning rod 205 is threadedly installed on the fixing bracket 201, and then the end of the fixing rod is rotated and inserted into the hole, so that the controller body 1 can be preliminarily positioned; then the fixing bolt 203 is threadedly installed into the installation hole 202 provided in the fixing bracket 201, and the fixing bracket 201 can be fixed to the wall or equipment, so as to facilitate the fixation of the controller body 1, and the diameter of one end of the installation hole 202 is larger than the diameter of the other end, which can facilitate the operator to take the fixing bolt 203 when disassembling the controller body 1.

[0034] When the present invention is used, first, when installing the controller body 1, a hole can be drilled on the wall or equipment. Two fixing brackets 201 are symmetrically installed on one side of the controller body 1. The two mounting grooves 204 provided on the fixing bracket 201 are aligned with the drilled holes, and then the positioning rod 205 is threadedly installed on the fixing bracket 201, and then the end of the positioning rod 205 is rotated and inserted into the hole position, so that the controller body 1 can be initially positioned; then the fixing bolt 203 is threadedly installed on the mounting hole 202 provided in the fixing bracket 201, and the fixing bracket 201 can be fixed on the wall or equipment, so as to facilitate the fixing of the controller body 1, and the diameter of one end of the mounting hole 202 is larger than the diameter of the other end, which can facilitate the operator to take the fixing bolt 203 when disassembling the controller body 1;

[0035] When installing the connecting wires on the controller body 1, multiple connecting wires can be distinguished first. Before installing them one by one, push the slider 602 set on the fixed plate 5 upward by hand. Since the fixed plate 5 is installed on the cover plate 301, when the slider 602 slides in the slide groove 601 provided in the fixed plate 5, the end of the slider 602 can drive the connecting rod 608 to slide. The fixed plate 5 is rotatably installed with a ball 607 near the connecting rod 608. When the connecting rod 608 slides, the ball 607 is driven to rotate, thereby facilitating the improvement of the sliding effect of the connecting rod 608. The connecting rod 608 is fixedly connected to the pressure block 604. When the connecting rod 608 drives the pressure block 604 to slide into the inside of the fixed plate 5, the end of the pressure block 604 can be aligned with the connecting rod 608. The compression spring 606 sleeved on the upper part is squeezed. When the compression spring 606 is in a compressed state, the operator can place the connecting wire between the pressing block 604 and the pad 603, and the rubber pad 605 is bonded to the pressing block 604. The pad 603 and the rubber pad 605 are all arranged in an arc structure, so that the connecting wire can be limited between the pressing block 604 and the pad 603, and the remaining connecting wires are initially limited in turn, which can prevent the connecting wires from being connected incorrectly during the installation process; at the same time, after the connecting wires are installed, the limiting of the connecting wires by the pressing block 604 and the rubber pad 605 can also prevent the connecting wires from being pulled out of the device by external force during the use of the controller body 1;

[0036] Since the connecting shaft 306 fixed on the cover plate 301 rotates in the controller body 1, when the inside of the controller body 1 needs to be repaired, the rotating rod 303 fixed in the controller body 1 is removed with a tool, and when the cover plate 301 is rotated, the two limit blocks 302 fixed on both sides can be driven to rotate out of the limit grooves 304 provided in the controller body 1, and the cover plate 301 drives the connecting shaft 306 to rotate, so that the end of the controller body 1 is in an open state, thereby facilitating the maintenance of the inside of the controller; when the end of the connecting line is installed on the wiring block 305 fixed on the cover plate 301, When the slider 402 is inserted into the cover 301, the slider 402 is pushed to drive the slider 402 to slide into the cover 301. Since a slide bar 403 is fixed inside the cover 301, when the slider 402 slides along the slide bar 403, the telescopic spring 404 sleeved on the slide bar 403 can be squeezed. When the slider 402 slides to the state where the slider 401 and the cover 301 are in conflict, it is convenient for the operator to insert the screwdriver into the wiring block 305, and then it is convenient to turn the screws on the wiring block 305, so that the connecting wire and the wiring block 305 can be connected without removing the cover 301.
