Technical Field

[0001] This invention relates to the field of photovoltaic anti-reverse diode technology, and particularly to a photovoltaic anti-reverse diode with multiple protection components. Background Technology

[0002] Photovoltaic power generation uses solar cells to directly convert sunlight into electrical energy. Its process is environmentally friendly and pollution-free, which is why it has attracted attention and is widely used. This device is a photovoltaic reverse protection diode, which is used to block the reverse current from the battery when the solar panel is not generating electricity, preventing the solar panel from overheating or being damaged, and ensuring the normal use of the solar panel. However, existing photovoltaic reverse protection diodes have many problems and defects.

[0003] Traditional photovoltaic anti-reverse diodes have the problem of inconvenient cable connection, making the process of connecting cables to devices cumbersome and requiring tools, which reduces the efficiency of cable connection to devices. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide a photovoltaic anti-reverse diode with multiple protection components to solve the problem of inconvenient cable connection mentioned in the background art. (II) Summary of the Invention

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a photovoltaic anti-reverse diode with multiple protection components, including a base plate, a housing, and a placement plate. The housing is fixed to the top of the base plate, and the interior of the housing is provided with a heat dissipation structure. Mounting holes are provided on both sides of the housing. The placement plate is installed on the top of the housing, and a mounting plate is installed on the top of the placement plate. The top of the mounting plate is provided with a fixing structure, and a protective structure is provided on one side of the top of the housing.

[0008] Preferably, the heat dissipation structure includes a heat-conducting shell, heat-conducting plates, heat sinks, mesh, and a fan. The heat-conducting shells are all fixed inside the outer shell, and heat sinks are fixed inside each heat-conducting shell. A fan is installed on one side of the inside of the heat-conducting shell, and mesh is fixed on both sides of the inside of the heat-conducting shell. Heat is absorbed by the heat-conducting plates and conducted into the interior of the heat-conducting shell, allowing the heat to diffuse into the air through the heat sinks. The mesh prevents dust from entering the interior of the heat-conducting shell.

[0009] Preferably, the heat-conducting sheet and the heat-conducting shell are welded together as an integral structure, and the mesh is symmetrically distributed along the vertical center line of the heat-conducting shell.

[0010] Preferably, the heat sink is arranged in several groups inside the heat-conducting shell, and the groups of heat sinks are distributed at equal intervals inside the heat-conducting shell. By increasing the surface area inside the heat-conducting shell through multiple groups of heat sinks, the heat dissipation from the heat-conducting shell into the air is accelerated.

[0011] Preferably, the protective structure includes a protective shell, rubber collars, a push plate, a retaining strip, and a retaining groove. The protective shell is installed on one side of the top of the outer shell. Rubber collars are fixed inside both sides of the protective shell. A retaining strip is fixed to the top of one side of the protective shell. A push plate is fixed to the top of the protective shell. The retaining groove is formed at the top of one side of the retaining groove. By covering the top of the outer shell with the protective shell, the cable and mounting plate are protected. At the same time, the rubber collar blocks the cable entry point, preventing dust and debris from entering the interior of the protective shell.

[0012] Preferably, the push plate and the slot form an engaging structure, and the protective shell and the outer shell form a rotating structure.

[0013] Preferably, two sets of rubber collars are provided, and the rubber collars are symmetrically distributed on the vertical center line of the protective shell.

[0014] Preferably, the fixing structure includes a support frame, a guide groove, a movable block, a pressure plate, a connecting seat, and a rotating rod. The support frame is fixed to the top of the mounting plate. Guide grooves are provided on both sides of the inside of the support frame. A rotating rod is inserted into the inside of the support frame, and a connecting seat is installed at the bottom of the rotating rod. A pressure plate is fixed to the connecting seat, and movable blocks are fixed on both sides of the pressure plate. By rotating the rotating rod, the rotating rod pushes the pressure plate down to press the cable onto the surface of the mounting plate. The connecting seat prevents the rotating rod from rotating the pressure plate, while the movable blocks and guide grooves prevent the pressure plate from rotating.

[0015] Preferably, the outer wall of the rotating rod is provided with external threads, and the inside of the support frame is provided with internal threads that cooperate with the external threads. This allows the rotating rod to move up and down through the internal threads of the support frame when it is rotated.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the beneficial effects of the present invention are: the photovoltaic anti-reverse diode with multiple protection components has a reasonable structure and has the following advantages:

[0018] (1) By rotating the rotating rod, the rotating rod pushes the pressure plate down to press the cable onto the surface of the mounting plate. The connecting seat prevents the rotating rod from rotating the pressure plate. At the same time, the moving block and the guide groove prevent the pressure plate from rotating. This realizes the easy connection function of this device, which makes it easy to connect and fix the cable to the device and connect the device to the circuit, thus improving the installation efficiency of the device. At the same time, the process of disassembling the cable is simple, which makes it easy for the staff to separate the cable from the device, thus improving the convenience of this device.

[0019] (2) By covering the top of the outer shell with a protective shell to protect the cable and the mounting plate, and at the same time blocking the cable entry point with a rubber collar to prevent dust and debris from entering the interior of the protective shell, the device achieves multiple protection functions. By protecting the wiring position of the device, dust and debris are prevented from affecting the connection between the cable and the mounting plate, ensuring the stability of the device operation and improving the functionality of the device.

[0020] (3) Heat is absorbed by the heat-conducting plate and introduced into the interior of the heat-conducting shell, so that the heat is diffused into the air through the heat sink. The mesh prevents dust from entering the interior of the heat-conducting shell, thereby realizing the efficient heat conduction function of this device, which facilitates the timely discharge of the heat accumulated inside the device and prevents the device from overheating and burning.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] Example 1

[0032] Please see Figure 1-6 This invention provides a photovoltaic anti-reverse diode with multiple protection components, including a base plate 1, a housing 3, and a placement plate 4. The housing 3 is fixed to the top of the base plate 1, and the interior of the housing 3 is provided with a heat dissipation structure 2. Mounting holes 8 are provided on both sides of the housing 3. The placement plate 4 is installed on the top of the housing 3, and a mounting plate 7 is installed on the top of the placement plate 4. A fixing structure 6 is provided on the top of the mounting plate 7. A protective structure 5 is provided on one side of the top of the housing 3. The fixing structure 6 includes a support frame 601, a guide groove 602, and a moving block. 603, pressure plate 604, connecting seat 605 and rotating rod 606, support frame 601 is fixed to the top of mounting plate 7, guide grooves 602 are opened on both sides inside the support frame 601, rotating rod 606 is inserted inside the support frame 601, and connecting seat 605 is installed at the bottom of the rotating rod 606. Pressure plate 604 is fixed to the connecting seat 605, and moving blocks 603 are fixed on both sides of the pressure plate 604. External thread is provided on the outer wall of the rotating rod 606, and internal thread is provided inside the support frame 601 to cooperate with the external thread.

[0033] The working principle of the photovoltaic anti-reverse diode with multiple protection components based on Embodiment 1 is as follows: By placing the cable at the bottom of the pressure plate 604, the rotating rod 606 is rotated, causing the rotating rod 606 to move downward through the internal thread of the support frame 601. Then, the rotating rod 606 pushes the pressure plate 604 downward through the connecting seat 605, so that the pressure plate 604 presses the cable onto the surface of the mounting plate 7, connecting the cable to the device. The connecting seat 605 rotates between the rotating rod 606 and the pressure plate 604 to prevent the rotating rod 606 from driving the pressure plate 604 to rotate. At the same time, the moving block 603 slides inside the guide groove 602, so that the pressure plate 604 can only move up and down.

[0034] Example 2

[0035] This embodiment includes: a heat dissipation structure 2 comprising a heat-conducting shell 201, heat-conducting plates 202, heat sinks 203, mesh 204, and a fan 205. The heat-conducting shells 201 are all fixed inside the outer shell 3. Heat sinks 203 are fixed inside the heat-conducting shells 201. A fan 205 is installed on one side inside the heat-conducting shells 201. Mesh 204 is fixed on both sides inside the heat-conducting shells 201. Heat-conducting plates 202 are fixed on both sides of the heat-conducting shells 201. Several groups of heat sinks 203 are arranged inside the heat-conducting shells 201, and the groups of heat sinks 203 are evenly distributed inside the heat-conducting shells 201. The heat-conducting plates 202 and the heat-conducting shells 201 are welded together. The mesh 204 is symmetrically distributed on the vertical center line of the heat-conducting shells 201.

[0036] In this embodiment, during production, the heat-conducting plate 202 is tightly attached to the heat-generating part. When the device generates heat, the heat-conducting plate 202 absorbs the heat and introduces it into the interior of the heat-conducting shell 201. Then, the fan 205 is started to accelerate the airflow inside the heat-conducting shell 201, which facilitates the air carrying heat. The heat sink 203 increases the surface area inside the heat-conducting shell 201, accelerating the diffusion of heat from the heat-conducting shell 201 into the air. The mesh 204 prevents dust from entering the interior of the heat-conducting shell 201.

[0037] Example 3

[0038] This embodiment includes: the protective structure 5 includes a protective shell 501, a rubber collar 502, a push plate 503, a locking strip 504, and a locking groove 505. The protective shell 501 is installed on one side of the top of the outer shell 3. Rubber collars 502 are fixed inside both sides of the protective shell 501. A locking strip 504 is fixed at the top of one side of the protective shell 501. A push plate 503 is fixed at the top of the protective shell 501. The locking groove 505 is opened at the top of one side of the locking groove 505. The push plate 503 and the locking groove 505 form an engaging structure. The protective shell 501 and the outer shell 3 form a rotating structure. Two sets of rubber collars 502 are provided. The rubber collars 502 are symmetrically distributed on the vertical center line of the protective shell 501.

[0039] In this embodiment, the cable is passed through the rubber collar 502 and connected to the mounting plate 7. By pulling the protective shell 501 to rotate around the outer shell 3, the protective shell 501 covers the top of the outer shell 3, blocking the cable and the mounting plate 7 and preventing external objects from contacting the cable and the mounting plate 7. The position of the protective shell 501 is fixed by the clip 504 being inserted into the slot 505. The rubber collar 502 blocks the entry point of the cable, preventing dust and debris from entering the interior of the protective shell 501.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
