[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a photovoltaic inverter multilayer cavity device. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 13 As shown, the present invention provides: a photovoltaic inverter multilayer cavity device, comprising a shell 1, a cover plate 11 is detachably mounted on the shell 1, a plurality of movable frames 2 are slidably connected to the inner wall of the shell 1, each of the movable frames 2 is provided with a partition mechanism, the partition mechanism comprises a plurality of partitions 3 rotatable on the movable frame 2, the plurality of partitions 3 are used to separate the interior of the shell 1 and form a multilayer cavity, a push rod 33 is slidably connected to the interior of each partition 3, two adjacent partitions 3 are connected by the push rod 33, a movable plate 4 is slidably connected to the movable frame 2, a driving mechanism for driving the partition 3 to rotate is provided on the movable plate 4, and the driving mechanism comprises a connecting rod 43 rotatably connected to the top of the movable plate 4; By driving the movable frame 2 and driving the partition 3 to move, the partition 3 slides on the inner wall of the shell 1, so that transverse cavities of different sizes can be formed; The connecting rod 43 is driven to move by the movable plate 4, and the connecting rod 43 moves to the partition 3 and is connected to both ends of the partition 3. Then, the connecting rod 43 is driven to drive the partition 3 to rotate, so that multiple partitions 3 rotate synchronously around the connecting rod 43, thereby forming a longitudinal cavity as needed.

[0023] Specifically, in order to install various components for use and keep the components from interfering with each other, a partition 3 is generally provided inside the housing 1, and the interior of the housing 1 is divided into a plurality of cavities by the partition 3, each cavity being suitable for installing different functional modules; When the existing photovoltaic inverter divides the interior of the housing 1 into cavities by the partition 3, since the shape of the partition 3 is fixed, the formed cavity will change with the shape of the partition 3. For example, when the partition 3 is arranged horizontally, the internal cavity of the housing 1 is a plurality of cavities extending horizontally. When the components need to be installed vertically, the partition 3 requires additional brackets or structures to meet the installation requirements of the components, thereby increasing the complexity and difficulty of installation. In order to solve the above problems, the present invention is used as follows: when the housing 1 is used and it is necessary to divide the interior thereof into a plurality of transverse cavities, the interior of the housing 1 can be divided into a plurality of transverse cavities by driving a plurality of movable racks 2 to move, and the movable racks 2 drive the partitions 3 above them to move synchronously, and then the user can install the components in each cavity, and at the same time, by driving each movable rack 2 to slide to different heights in the housing 1, the distance between each transverse cavity can be adjusted; When the internal cavity of the shell 1 needs to be divided into a longitudinal cavity, the movable plate 4 can be driven to slide on the surface of the movable frame 2, and the movable plate 4 drives the connecting rod 43 to move synchronously. The connecting rod 43 moves to the partition 3 next to the movable frame 2, and the two ends of the movable plate 4 and the partition 3 are driven to be connected and fixed to each other, and at the same time, the push rod 33 inside the partition 3 is driven to move, so that the push rod 33 is stored inside the partition 3 and is disconnected from the movable frame 2, and then the connecting rod 43 is driven to rotate, and the connecting rod 43 drives multiple partitions 3 to rotate synchronously. The multiple partitions 3 rotate ninety degrees around the connecting rod 43 to form a longitudinal cavity; The present invention can form changes in the longitudinal cavity and the transverse cavity by rotating the partition 3 to different angles according to the needs of the user, thereby being able to adapt to the installation requirements of photovoltaic inverter components of different sizes. At the same time, the rotation of the partition 3 can adjust the space inside the cavity. When the staff installs or removes the photovoltaic inverter parts, there is a larger space for operation, thereby improving the work efficiency of installation and maintenance.

[0024] like Figure 2 As shown, the mobile frame 2 includes a positioning rod 12 fixedly connected to the inside of the shell 1, and the surface of the positioning rod 12 is slidably connected to the inside of the mobile frame 2, a plurality of positioning holes 121 are provided on the positioning rod 12, and a positioning plate 221 is slidably connected to the inside of the mobile frame 2, a fixing rod 222 is fixedly connected to the positioning plate 221, and the sizes of the fixing rod 222 and the positioning hole 121 match.

[0025] Specifically, when it is necessary to adjust the mobile frame 2 to move to different heights, the mobile frame 2 can be driven to slide on the positioning rod 12. After the mobile frame 2 slides to a suitable height, the positioning plate 221 is driven to slide inside the mobile frame 2. The positioning plate 221 drives the fixing rod 222 to be inserted into the positioning hole 121, thereby completing the fixed limit of the mobile frame 2.

[0026] like Figure 5 As shown, the internal thread of the positioning plate 221 is connected with a first bidirectional screw rod 22 , and the first bidirectional screw rod 22 is rotatably connected to the inside of the moving frame 2 .

[0027] Specifically, by rotating the first bidirectional screw 22, the two positioning plates 221 can be driven to slide synchronously. When the mobile frame 2 needs to be fixed, the two positioning plates 221 are driven close to each other, and the positioning plate 221 can drive the fixing rod 222 to be inserted into the interior of the positioning hole 121, thereby completing the fixing operation of the mobile frame 2.

[0028] like Figure 4 As shown, the movable frame 2 includes a support frame 21, which is fixedly connected to the lower surface of the movable frame 2, and the support frame 21 is used to support the partition 3. A limiting groove 211 is arranged inside the support frame 21, and the movable plate 4 and the inner wall of the limiting groove 211 are slidably connected.

[0029] Specifically, the support frame 21 can support the movable plate 4 so that the movable plate 4 can slide stably under the multiple partitions 3. At the same time, the support frame 21 can also support the partitions 3 to maintain the stability of the partitions 3 when installing parts.

[0030] like Figure 6 - Fig. 9 As shown, one end of the connecting rod 43 is rotatably connected to a splint 42, the splint 42 and the internal sliding connection of the movable plate 4, the internal sliding connection of the connecting rod 43 is provided with a limiting bead 431, a third spring 432 is fixedly connected between the limiting beads 431, the partition 3 is fixedly connected to a connecting sleeve 31, a tooth groove is arranged inside the connecting sleeve 31, and the size of the tooth groove matches the size of the limiting bead 431.

[0031] Specifically, when the movable plate 4 slides, it drives the clamp plate 42 to slide synchronously, and the clamp plate 42 drives the connecting rod 43 to move synchronously. The connecting rod 43 moves to the baffle at the specified position. At this time, the driving clamp plate 42 slides on the surface of the movable plate 4, so that the clamp plate 42 drives the connecting rod 43 to move toward one end of the partition 3, and the connecting rod 43 drives the limiting bead 431 to enter the connecting sleeve 31 at one end of the partition 3. At this time, the limiting bead 431 is squeezed and maintained by the third spring 432 and engaged with the internal tooth groove of the connecting sleeve 31, so that the connection and fixation between the connecting rod 43 and the partition 3 can be completed.

[0032] like Fig.10 - Fig.13 As shown, the partition 3 is internally slidably connected with a first iron rod 32, one end of the first iron rod 32 is fixedly connected with an elastic telescopic rod 322, the upper surface of the first iron rod 32 is fixedly connected with a cone sleeve 321, the partition 3 is internally slidably connected with a push rod 33, a second spring 343 is fixedly connected between the push rod 33 and the partition 3, and a first limiting hole 5 is opened on one side of the partition 3 and the movable frame 2, and the size of the first limiting hole 5 matches the size of the limiting rod 342.

[0033] Specifically, when the connecting rod 43 enters the interior of the connecting sleeve 31, the connecting rod 43 squeezes the first iron rod 32 to slide toward the inner side of the partition 3. The first iron rod 32 squeezes the elastic telescopic rod 322 and drives the cone sleeve 321 to move synchronously. The cone sleeve 321 slides toward the inner side of the partition 3, so that the second spring 343 drives the push rod 33 to slide toward one side of the cone sleeve 321, and the push rod 33 can be driven to disengage from the limiting frame or the first limiting hole 5 inside the front partition 3. At this time, the connecting rod 43 is driven to rotate. The connecting rod 43 engages with the tooth groove through the limiting bead 431, so that the partition 3 rotates. Since the limiting rod 342 here is disengaged from the front In the first limiting hole 5 of the square, the partition 3 here drives the partition 3 behind it to rotate synchronously. The user can drive the partition 3 at any position to rotate and form longitudinal cavities of various sizes, which can meet the installation of parts of different sizes. At the same time, the partition 3 can be driven to rotate, so that some partitions 3 are in a horizontal setting and some partitions 3 are in an inclined setting, so as to better utilize the longitudinal cavity and the horizontal cavity, which can not only improve the utilization rate of the internal space of the shell 1, but also allow the parts to be placed at different angles on the partition 3, thereby increasing the heat dissipation area of ​​the parts and improving the heat dissipation efficiency.

[0034] like Figure 7 and Figure 8 As shown, a worm wheel 433 is fixedly connected to the surface of the connecting rod 43 , a worm 421 is fixedly connected to one side of the clamping plate 42 , and the worm 421 and the worm wheel 433 are meshed with each other.

[0035] Specifically, when the connecting rod 43 needs to be driven to rotate, the worm 421 is rotated, and the worm 421 and the worm wheel 433 are engaged to drive the connecting rod 43 to rotate. At the same time, the worm 421 and the worm wheel 433 have a self-locking property, which can improve the stability of the partition 3 after rotation.

[0036] like Figure 6 - Figure 8 As shown, the internal thread of the clamping plate 42 is connected with a second bidirectional screw rod 41 , and the second bidirectional screw rod 41 is rotatably connected to the inside of the moving plate 4 .

[0037] Specifically, when it is necessary to connect the connecting rod 43 and the partition 3, the second bidirectional screw rod 41 can be driven to rotate, and the second bidirectional screw rod 41 drives the two clamps 42 to approach each other, and the clamps 42 drive the connecting rod 43 to slide toward the inside of the connecting sleeve 31 on the surface of the partition 3, and the connecting rod 43 drives the limiting bead 431 to enter the tooth groove of the connecting sleeve 31 to complete the connection between the connecting rod 43 and the partition 3.

[0038] like Fig. 9 - Fig.13As shown, the push rod 33 is internally slidably connected to the third iron rod 34, one end of the third iron rod 34 is rotatably connected to the connecting rod 341, one end of the connecting rod 341 is rotatably connected to the limiting rod 342, the limiting rod 342 and the push rod 33 are internally slidably connected, the cone sleeve 321 is fixedly connected to the second iron rod 323, one end of the connecting rod 43 is fixedly connected to the electromagnet 434, and the first limiting hole 5 is provided with a second limiting hole 51, and the size of the second limiting hole 51 matches the size of the limiting rod 342.

[0039] Specifically, when a transverse cavity and an inclined cavity need to be formed, the partition 3 can be driven to rotate into an inclined state. At this time, one end of the partition 3 is away from the inner wall of the shell 1 and has a certain moving space. Therefore, during or after the partition 3 rotates, when shaking occurs and causes the first iron rod 32 to move, the limiting rod 342 inside the rear partition 3 will slide from the first limiting hole 5 inside the front partition 3, causing the rear partition 3 to fall off, thereby making it difficult to form an inclined cavity. In order to avoid the above problems, under normal conditions, the limiting rod 342 is located inside the second limiting hole 51, which can limit the push rod 33, so that the push rod 33 is always inside the first limiting hole 5. When it is necessary to drive the partition 3 to rotate, the electromagnet 434 can be turned on to work, the movable plate 4 drives the clamping plate 42 to move, the clamping plate 42 drives the connecting rod 43 to move, and the connecting rod 43 drives the electromagnet 434 to move. The electromagnet 434 generates magnetic force at work. Because the first iron rod 32 and the second iron rod 323 are made of metal materials, the first iron rod 32 and the second iron rod 323 will be magnetized under the magnetic force of the electromagnet 434. Therefore, magnetic force will be generated on the surfaces of the first iron rod 32 and the second iron rod 323, and then the connecting rod 43 drives the electromagnet 434 to push the first iron rod 32 to move, so that the second iron rod 323 When the push rod 33 is moved to the third iron rod 34, since the second iron rod 323 has magnetic force at this time, the second iron rod 323 will attract the third iron rod 34 and move it to the inside of the partition 3. The third iron rod 34 moves and stretches the second spring 343. The third iron rod 34 drives the connecting rod 341 to rotate. The connecting rod 341 drives the limiting rod 342 to slide to the inside of the push rod 33, so that the push rod 33 is separated from the inside of the second limiting hole 51. At this time, the push rod 33 slides to the inside of the partition 3 and is separated from the inside of the first limiting hole 5 under the action of the first spring 331, and then the partition 3 here can be driven to rotate. When the partition 3 is driven to rotate, the electromagnet 434 is closed. At this time, the push rod 33 is squeezed by the moving rod and the electromagnet 434, so the push rod 33 is relatively stable, so that the baffle remains stable at this time. The device can prevent the push rod 33 from being separated from the inside of the first limit block by cooperating with the limit rod 342 and the second limit hole 51, thereby avoiding the problem that when the partition 3 is driven to rotate and tilt, the first iron rod 32 shakes and affects the position of the push rod 33, causing the push rod 33 to be separated from the first limit hole 5, causing the partition 3 to fall and thus unable to form a tilted cavity.

[0040] like Figure 7 - Fig. 9 As shown, an extrusion sleeve 44 is fixedly connected to the upper surface of the movable plate 4, and one end of the connecting sleeve 31 is rotatably connected to a protective plate 311.

[0041] Specifically, the extrusion sleeve 44 is used to extrude the limiting bead 431 so that the limiting bead 431 is located in the inner wall of the connecting rod 43, thereby facilitating the limiting bead 431 to slide into the interior of the connecting sleeve 31 and engage with the tooth groove. At the same time, the protective plate 311 is used to cover one end of the connecting sleeve 31 to prevent impurities from adhering to the tooth groove of the first iron rod 32 or the connecting sleeve 31. At the same time, the connecting sleeve 31 can position the movable plate 4, thereby facilitating the user to quickly drive the movable plate 4 to move to the designated partition 3 for connection operation.

[0042] Working principle: When the shell 1 is used, when the inside of the shell 1 needs to be divided into a plurality of transverse cavities, the moving frame 2 is driven to slide on the positioning rod 12. After the moving frame 2 slides to a suitable height, the first bidirectional screw 22 is rotated to drive the two positioning plates 221 to slide synchronously. The positioning plates 221 slide inside the moving frame 2, and the positioning plates 221 drive the fixing rods 222 to be inserted into the inside of the positioning holes 121, so that the fixed limit of the moving frame 2 can divide the inside of the shell 1 into a plurality of transverse cavities of different sizes. When it is necessary to divide the interior of the shell 1 into multiple longitudinal cavities, open the protective plate 311 at the designated position of the partition 3, and drive the movable plate 4 to slide in the limiting groove 211 inside the support frame 21, the movable plate 4 moves to the protective plate 311 for limiting, then turn on the electromagnet 434, and rotate the second bidirectional screw rod 41, the second bidirectional screw rod 41 drives the two clamping plates 42 to approach each other, the clamping plate 42 drives the connecting rod 43 to slide toward the inside of the connecting sleeve 31 on the surface of the partition 3, and the connecting rod 43 drives the limiting bead 431 to enter the tooth groove of the connecting sleeve 31 The connection between the connecting rod 43 and the partition 3 is completed, the connecting rod 43 drives the electromagnet 434 to contact the first iron rod 32, the electromagnet 434 works to generate magnetic force, the first iron rod 32 and the second iron rod 323 are magnetized, so that the surfaces of the first iron rod 32 and the second iron rod 323 will generate magnetic force, the electromagnet 434 pushes the first iron rod 32 to move, the first iron rod 32 slides toward the inner side of the partition 3, the first iron rod 32 squeezes the elastic telescopic rod 322 and drives the cone sleeve 321 to move synchronously, so that the second iron rod 323 moves to At the third iron rod 34, since the second iron rod 323 has magnetic force at this time, the second iron rod 323 will attract the third iron rod 34 to move toward the inside of the partition 3, and the third iron rod 34 moves and stretches the second spring 343. The third iron rod 34 drives the connecting rod 341 to rotate, and the connecting rod 341 drives the limiting rod 342 to slide toward the inside of the push rod 33, so that the push rod 33 is separated from the inside of the second limiting hole 51. At this time, under the action of the first spring 331, the push rod 33 slides toward the inside of the partition 3 and separates from the inside of the first limiting hole 51 and Keep it in contact with the surface of the cone sleeve 321, then rotate the worm 421, the worm 421 and the worm wheel 433 are meshed, the worm wheel 433 drives the connecting rod 43 to rotate, the connecting rod 43 is meshed with the limit bead 431 and the tooth groove and drives the partition 3 to rotate, multiple partitions 3 are rotated ninety degrees around the connecting rod 43, so that multiple partitions 3 become longitudinal, and longitudinal partitions 3 can be formed, and then the partitions 3 on the surface of other movable frames 2 are driven to make multiple transverse partitions 3 turn into longitudinal partitions 3, so as to form a longitudinal cavity, which can be used to place large equipment of different sizes.
