Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically a photovoltaic power generation energy storage conversion device. Background Technology

[0002] A photovoltaic inverter is a power regulation device composed of semiconductor devices, mainly used to convert direct current (DC) power into alternating current (AC) power. It generally consists of a boost circuit and an inverter bridge circuit. The boost circuit increases the DC voltage of the solar cells to the DC voltage required for the inverter's output control; the inverter bridge circuit then converts the boosted DC voltage into an equivalent AC voltage of the commonly used frequency.

[0003] Application number CN202322500052.2 discloses a photovoltaic power generation and energy storage conversion device, including a body, a cabinet door, and a display panel. The cabinet door is movably disposed on the surface of the body, and the display panel is embedded in the surface of the cabinet door. A wiring groove is formed on the back surface of the body, and a terminal block is provided in the inner cavity of the wiring groove. A sliding groove is formed on the surface of the wiring groove, and a baffle is slidably disposed in the inner cavity of the sliding groove. A wire conduit is conductively connected to both ends of the wiring groove. The surface of the wire conduit is flush with the back surface of the body, and a wire-passing groove is formed on the side wall surface of the wire conduit. The connecting wire of the photovoltaic power generation module is connected to the terminal block. The free end of the wire is inserted into the wire conduit and exits through the wire-passing groove. The wire-passing groove overlaps with the wire-passing hole on the mounting bracket. The baffle can seal the wiring groove, which can hide the connection between the wire and the body and the connecting wire, preventing the wire from being exposed and damaged, and improving the safety during use.

[0004] This device relies solely on conduit and conduit channels for initial wire positioning. Lacking an adjustable fixing structure, it struggles to accommodate stable installations of various wire specifications. When faced with incompatible wires, it may fail to secure them effectively, impacting the stability of power transmission. Furthermore, the structure primarily conceals the wires by enclosing the wiring channel with baffles, relying solely on the simple positioning of the conduit and conduit channels for wire fixation. During device operation, wires are prone to loosening and may even detach from the conduit or conduit, affecting the device's normal operation. Utility Model Content

[0005] The purpose of this invention is to provide a photovoltaic power generation and energy storage conversion device to solve the problem of insufficient adaptability.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a photovoltaic power generation and energy storage conversion device, comprising a fixed heat dissipation structure and a wiring installation structure. The wiring installation structure is installed on the inner walls of both sides of the fixed heat dissipation structure. The wiring installation structure includes a fixed frame, and three sets of arc-shaped grooves are respectively opened on the inner walls of both sides of the fixed frame. An arc-shaped convex surface is formed between every two adjacent arc-shaped grooves. Three sets of adjustable screws are vertically threaded to the inner wall of the top of the fixed frame. The bottom ends of the three sets of adjustable screws penetrate through and extend to the bottom of the fixed frame. A pressure rod is fixedly connected to the bottom end of the three sets of adjustable screws. Sliding grooves are respectively opened on the inner walls of the two ends of the pressure rods. Sliding blocks are slidably connected to the inner walls of the sliding grooves on both sides. An arc-shaped abutment is fixedly connected to one outer end of the two sliding blocks. A spring is sleeved on the outside of the sliding block between the pressure rod and the arc-shaped abutment. The arc-shaped abutment is adapted to the arc-shaped groove.

[0007] The purpose of this setup is that, during the use of the device, when it is necessary to install the wiring of the photovoltaic power generation and energy storage conversion device, the wiring installation structure is first installed on the inner walls of both sides of the fixed heat dissipation structure. In the wiring installation structure, the fixed frame serves as the basic support component, and the three sets of arc-shaped grooves on its inner walls and the arc-shaped convex surfaces formed between adjacent arc-shaped grooves provide a structural foundation for the subsequent wiring fixation. Next, operate the three sets of adjustable screws vertically threaded to the inner wall of the top of the fixed frame. Since the adjustable screws are threaded to the inner wall of the top of the fixed frame, rotating the adjustable screws will move them downwards along the thread direction. The bottom end of the adjustable screw penetrates and extends to the bottom of the fixed frame and is fixedly connected to the pressure rod. Therefore, as the adjustable screws move downwards, they will drive the pressure rod to move downwards synchronously. As the pressure rod moves downward, the slider in the groove on the inner wall at both ends and the arc-shaped abutment fixedly connected to one end of the slider also move. The arc-shaped abutment matches the arc-shaped groove on the inner wall on both sides of the fixed frame. When the arc-shaped abutment moves to the position of the arc-shaped groove, under the action of the spring force, the arc-shaped abutment will move towards the arc-shaped groove, so that the arc-shaped abutment is in close contact with the arc-shaped groove, thereby initially limiting the position of the pressure rod. Next, place the wiring to be installed into the three sets of mounting arc grooves opened opposite each other on the bottom of the fixed frame and the pressure rod. Then continue to rotate the adjustable screw to make the pressure rod press the wiring down further. Utilize the arc structure of the mounting arc groove and the pressure of the pressure rod to stably fix the wiring in the fixed frame, thus completing the wiring installation and fixing work. With the cooperation of adjustable screws, pressure rods, and arc-shaped abutments, the device can adapt to different specifications of wiring and can stably install and fix various wirings, improving the compatibility of the device's wiring connections. By utilizing the arc-shaped structure of the mounting arc groove and the pressure of the pressure rod, combined with the limiting effect of the arc-shaped abutment and the arc groove, the wiring can be firmly fixed in the fixed frame, effectively preventing the wiring from loosening or falling off during device operation, and ensuring the stable operation of power transmission and other functions.

[0008] Furthermore, the outer ends of the arc-shaped abutments on both sides apply pressure to the parallel arc-shaped grooves on both sides, and the bottom of the fixed frame and the pressure rod are respectively provided with three sets of mounting arc-shaped grooves.

[0009] The purpose of this design is that, during the use of the device, the outer ends of the two curved abutments, under the action of the springs, apply pressure to the parallel curved grooves on both sides, so that the curved abutments and the curved grooves fit tightly together. At the same time, the three sets of mounting curved grooves on the adjacent surfaces of the fixed frame and the bottom of the pressure rod are opposite each other, providing curved space for wiring placement and assisting in the stable installation of wiring.

[0010] Furthermore, the fixed heat dissipation structure includes a cabinet, and a connection groove is provided on the inner wall of the back of the cabinet. Three sets of ports are arranged at the bottom of the connection groove, and a wire is inserted into the inner wall of each set of ports.

[0011] The purpose of this design is to allow for the installation of a wiring groove on the inner wall of the cabinet with a fixed heat dissipation structure during the use of the device. The inner walls of the three sets of ports at the bottom are used to insert wiring, achieving initial connection between the wiring and the internal structure of the cabinet, and providing a wiring foundation for subsequent power transmission.

[0012] Furthermore, the other end of the three sets of wiring extends to the outside of the cabinet through the through hole, and the wire of each set of wiring is respectively located in the corresponding mounting arc groove between the wiring and the pressure rod.

[0013] The purpose of this design is that, during the use of the device, the other end of the three sets of wiring extends to the outside through the through holes of the cabinet, and the wire of each set of wiring is located in the corresponding mounting arc groove between the wiring and the pressure rod. The mounting arc groove is used to limit and fix the wire, ensuring that the wiring is stable in the device and facilitating operations such as power transmission.

[0014] Furthermore, the back of the cabinet has several ventilation holes, and cooling fan assembly one is fixedly installed on the upper and lower inner walls of the cabinet, while cooling fan assembly two is fixedly installed on the four inner walls of the back of the cabinet.

[0015] The purpose of this design is that during the use of the device, several heat dissipation holes on the back of the cabinet can achieve natural heat dissipation. At the same time, the cooling fan group 1 on the upper and lower inner walls of the cabinet and the cooling fan group 2 on the inner walls around the back are activated to accelerate the airflow inside the cabinet and quickly dissipate the heat generated by the photovoltaic power generation and energy storage conversion, ensuring that the device operates at a suitable temperature.

[0016] Furthermore, flow holes are respectively opened and penetrated on the upper and lower outer walls of the connecting wire groove, and the first cooling fan group and the second cooling fan group are respectively located on the back and upper and lower sides of the connecting wire groove.

[0017] The purpose of this design is that, during the use of the device, the flow holes on the upper and lower outer walls of the wiring trough cooperate with the cooling fan group one and cooling fan group two. The cooling fan group one and cooling fan group two are respectively located on the back and upper and lower sides of the wiring trough, forming a more efficient airflow path through the flow holes, thereby enhancing the heat dissipation effect and promptly removing heat from the wiring trough and other parts.

[0018] This utility model has the following beneficial effects: (1) This utility model, through the setting of arc-shaped abutment, adjustable screw and pressure rod, and through the cooperation of components such as adjustable screw, pressure rod and arc-shaped abutment, can adapt to different specifications of wiring and can stably install and fix various wirings; the arc structure of the arc groove and the pressure of the pressure rod, combined with the limiting effect of the arc-shaped abutment and the arc groove, effectively prevent the wiring from loosening or falling off during the operation of the device.

[0019] (2) By setting up cooling fan group one and cooling fan group two, the heat dissipation holes on the back of the cabinet can achieve natural heat dissipation. At the same time, the cooling fan group one on the upper and lower inner walls of the cabinet and the cooling fan group two on the inner walls around the back are activated to accelerate the air flow inside the cabinet and quickly dissipate the heat generated by photovoltaic power generation and energy storage conversion, ensuring that the device operates at a suitable temperature.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 As shown, this utility model is a photovoltaic power generation and energy storage conversion device, including a fixed heat dissipation structure 1 and a wiring installation structure 2. The wiring installation structure 2 is installed on the inner walls of both sides of the fixed heat dissipation structure 1. The wiring installation structure 2 includes a fixed frame 202. Three sets of arc-shaped grooves 203 are respectively opened on the inner walls of both sides of the fixed frame 202. An arc-shaped convex surface 204 is formed between every two adjacent arc-shaped grooves 203. Three sets of adjustable screws 210 are vertically threaded onto the inner wall of the top of the fixed frame 202. The bottom end of 210 extends through and into the bottom of the fixed frame 202. The bottom ends of the three sets of adjustable screws 210 are fixedly connected to pressure rods 205. The inner walls of both ends of the pressure rods 205 are respectively provided with sliding grooves 206. The inner walls of the sliding grooves 206 on both sides are respectively slidably connected to sliders 207. The outer ends of the sliders 207 on both sides are fixedly connected to arc-shaped blocks 208. The sliders 207 are fitted with springs 209 on the outside between the pressure rods 205 and the arc-shaped blocks 208. The arc-shaped blocks 208 are adapted to the arc-shaped grooves 203.

[0025] The purpose of this setup is that, during the use of the device, when it is necessary to install the wiring of the photovoltaic power generation and energy storage conversion device, the wiring installation structure 2 is first installed on the inner walls of both sides of the fixed heat dissipation structure 1. In the wiring installation structure 2, the fixed frame 202 serves as the basic support component, and the three sets of arc grooves 203 on its inner walls and the arc-shaped convex surface 204 formed between adjacent arc grooves provide a structural foundation for the subsequent wiring fixation. Next, the three sets of adjustable screws 210 vertically threaded on the inner top wall of the fixed frame 202 are operated. Since the adjustable screws 210 are threaded to the inner top wall of the fixed frame 202, rotating the adjustable screws 210 allows them to move downwards along the thread direction. The bottom end of the adjustable screw 210 penetrates and extends to the bottom of the fixed frame 202 and is fixedly connected to the pressure rod 205. Therefore, as the adjustable screw 210 moves downwards, it will drive the pressure rod 205 to move downwards synchronously. As the pressure rod 205 moves downward, the slider 207 in the groove 206 on the inner wall at both ends and the arc-shaped abutment 208 fixedly connected to one side of the slider 207 also move. The arc-shaped abutment 208 is adapted to the arc-shaped groove 203 on the inner wall on both sides of the fixed frame 202. When the arc-shaped abutment 208 moves to the position of the arc-shaped groove 203, under the elastic force of the spring 209, the arc-shaped abutment 208 will move towards the arc-shaped groove 203, so that the arc-shaped abutment 208 and the arc-shaped groove 203 are in close contact, thereby initially limiting the position of the pressure rod 205. Next, place the wiring to be installed into the three sets of mounting arc grooves 211 that are opened opposite each other on the bottom adjacent surfaces of the fixed frame 202 and the pressure rod 205. Then, continue to rotate the adjustable screw 210 so that the pressure rod 205 presses the wiring further downward. Utilize the arc structure of the mounting arc groove 211 and the pressure of the pressure rod 205 to stably fix the wiring in the fixed frame 202, thus completing the wiring installation and fixing work. With the cooperation of components such as the adjustable screw 210, pressure rod 205, and arc-shaped abutment 208, it can adapt to different specifications of wiring and can stably install and fix various wirings, improving the compatibility of the device with the connecting wires. By utilizing the arc structure of the arc groove 211 and the pressure of the pressure rod 205, combined with the limiting effect of the arc abutment 208 and the arc groove 203, the wiring can be firmly fixed in the fixed frame 202, effectively preventing the wiring from loosening or falling off during the operation of the device, and ensuring the stable operation of power transmission and other work.

[0026] The outer ends of the two curved abutment blocks 208 apply pressure to the two parallel curved grooves 203. The bottom of the fixed frame 202 and the pressure rod 205 are respectively provided with three sets of mounting curved grooves 211.

[0027] The purpose of this arrangement is that, during the use of the device, the outer ends of the two curved surface blocks 208, under the action of the spring 209, apply pressure to the parallel curved grooves 203 on both sides, so that the curved surface blocks 208 and the curved grooves 203 fit tightly together. At the same time, the three sets of mounting curved surface grooves 211 on the adjacent bottom surfaces of the fixed frame 202 and the pressure rod 205 are opposite each other, providing curved surface space for wiring placement and assisting in the stable installation of wiring.

[0028] The fixed heat dissipation structure 1 includes a cabinet 101. A connection groove 102 is provided on the inner wall of the back of the cabinet 101. Three sets of ports 103 are arranged at the bottom of the connection groove 102. A wire 201 is inserted into the inner wall of each set of ports 103.

[0029] The purpose of this design is that, during the use of the device, a connection groove 102 is opened on the inner wall of the back of the cabinet 101 that fixes the heat dissipation structure 1, and the inner wall of the three sets of ports 103 at the bottom is used to insert the wiring 201, so as to achieve the initial connection between the wiring and the internal structure of the cabinet, and provide a wiring basis for subsequent power transmission, etc.

[0030] The other end of the three sets of wiring 201 extends to the outside of the cabinet 101 through the through hole, and the wire of each set of wiring 201 is located in the corresponding mounting arc groove 211 between the wiring 201 and the pressure rod 205.

[0031] The purpose of this arrangement is that, during the use of the device, the other end of the three sets of wiring 201 extends to the outside through the through hole of the cabinet 101, and the wire of each set of wiring 201 is located in the corresponding mounting arc groove 211 between the wiring 201 and the pressure rod 205. The mounting arc groove 211 is used to limit and fix the wire, ensuring that the position of the wiring in the device is stable, which facilitates operations such as power transmission.

[0032] The back of the cabinet 101 has several ventilation holes 104. Cooling fan assembly 1 105 is fixedly installed on the upper and lower inner walls of the cabinet 101, and cooling fan assembly 2 106 is fixedly installed on the inner walls of the back of the cabinet 101.

[0033] The purpose of this design is that during the use of the device, the heat dissipation holes 104 on the back of the cabinet 101 can achieve natural heat dissipation. At the same time, the cooling fan group 105 on the upper and lower inner walls of the cabinet 101 and the cooling fan group 106 on the inner walls around the back are activated to accelerate the airflow inside the cabinet and quickly dissipate the heat generated by the photovoltaic power generation and energy storage conversion, ensuring that the device operates at a suitable temperature.

[0034] The upper and lower outer walls of the connecting cable groove 102 are respectively provided with flow holes 107, and the cooling fan assembly 105 and the cooling fan assembly 106 are respectively located on the back and upper and lower sides of the connecting cable groove 102.

[0035] The purpose of this design is that, during the use of the device, the flow holes 107 on the upper and lower outer walls of the wiring trough 102 cooperate with the cooling fan assembly 105 and the cooling fan assembly 106. The cooling fan assembly 105 and the cooling fan assembly 106 are respectively located on the back and upper and lower sides of the wiring trough 102, forming a more efficient airflow path through the flow holes 107, thereby enhancing the heat dissipation effect and promptly removing the heat from the wiring trough 102 and other parts.

[0036] When in use, first, with the help of the connection groove 102 on the back of the cabinet 101 in the fixed heat dissipation structure 1 and the three sets of ports 103 at the bottom, insert the wire 201 into the inner wall of the port 103 to complete the initial connection between the wire and the inside of the cabinet. Then, extend the other end of the wire 201 to the outside through the through hole of the cabinet 101. Next, the wiring mounting structure 2 installed on the inner walls of both sides of the fixed heat dissipation structure 1 is operated. The wire 201 is placed into the mounting arc groove 211 at the bottom of the fixed frame 202 and the pressure rod 205. The adjustable screw 210 at the top of the fixed frame 202 is rotated to drive the pressure rod 205 to move down. The arc abutment 208 on the pressure rod 205 cooperates with the arc groove 203 under the action of the spring 209 to limit the pressure rod 205. At the same time, the pressure rod 205 presses the wire 201. The arc structure of the mounting arc groove 211 is used to fix the wire stably. When the device is running, the heat dissipation holes 104 on the back of the cabinet 101 dissipate heat naturally. The cooling fan group 105 on the upper and lower inner walls and the cooling fan group 2 106 on the back are activated to accelerate airflow. The airflow holes 107 on the upper and lower parts of the wiring groove 102 allow the cooling fan group 105 and 2 106 to form an efficient flow path, quickly dissipating the heat generated by the photovoltaic power generation and energy storage conversion inside, ensuring the stable operation of the device.
