Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic grid-connected cabinets, and in particular discloses a photovoltaic grid-connected cabinet that is convenient for outdoor installation. Background Art

[0002] The photovoltaic grid-connected cabinet (PV grid-connected cabinet) is a core device in a photovoltaic power generation system. Its primary function is to convert the direct current (DC) electricity generated by the PV modules into alternating current (AC) and safely and stably feed this electricity into the power grid. It serves as a crucial bridge connecting the PV power generation system and the power grid. Typically, the internal components of a PV grid-connected cabinet are installed and wired in a factory or workshop. The pre-assembled cabinet is then transported to the site for mounting and external cable connections. During on-site installation, a brick-concrete base is constructed, onto which an I-shaped steel frame is secured. The PV grid-connected cabinet is ultimately connected to the I-shaped frame to ensure a stable attachment to the ground. Bolting is a common method of securing the PV grid-connected cabinet to the I-shaped frame.

[0003] However, to ensure the stability of the equipment, multiple sets of bolts are often required for reinforcement. This increase in the number of bolts undoubtedly increases the complexity and time-consuming nature of installation. Furthermore, due to the nature of bolt installation, it is impossible to save time by operating multiple bolts simultaneously, resulting in a low installation efficiency. Consequently, existing photovoltaic grid-connected cabinets suffer from inconvenient and time-consuming installation processes, necessitating optimization and improvement. Summary of the Invention

[0029] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0030] Example: A photovoltaic grid-connected cabinet that is easy to install outdoors, combined with Figure 1-Figure 5 As shown, it includes: a cabinet 1; a fixing assembly arranged in the cabinet 1, the cabinet 1 is stably fixed on the I-frame 31 using the fixing assembly, and a total of three sets of fixing assemblies are arranged in the cabinet 1. The fixing assembly is arranged in an independent space at the bottom of the cabinet 1, thereby being separated from the relevant equipment and wiring inside the cabinet 1;

[0031] The fixing assembly includes: a mounting head 2 fixedly mounted on the lower part of the left side wall of the cabinet 1; a supporting block 3 fixedly mounted on the bottom inner side of the cabinet 1; a connecting sleeve 4 slidably mounted between the mounting head 2 and the supporting block 3; a hook 5 fixedly mounted on the left end portion of the connecting sleeve 4, the hook 5 is used to grab the I-frame 31, and the hook 5 is located outside the cabinet 1; a connecting rod 6 slidably mounted on the right end portion of the connecting sleeve 4; a first spring 7 mounted on the connecting rod 6, and the two ends of the first spring 7 are fixedly mounted on the connecting rod 6 and the connecting sleeve 4; a slide rail 8 fixedly mounted on the lower part of the right side wall of the cabinet 1; a movable plate 9 slidably mounted on the slide rail 8; a rotating arm 10 rotatably mounted between the movable plate 9 and the connecting rod 6, the rotating arm 10 rotates to control the movable plate 9 to move up and down; a hook frame 11 fixedly mounted on the movable plate 9, the hook frame 11 is used to grab the I-frame 31, and the hook frame 11 of the three groups of fixing assemblies form a whole to increase the integrity between each group of fixing assemblies and improve the fixing stability of the fixing assemblies.

[0032] First, build a base 30 at the installation location of the photovoltaic grid-connected cabinet, and fix the I-frame 31 on the base 30. After that, the photovoltaic grid-connected cabinet can be installed:

[0033] Place the cabinet body 1 at the left part of the I-shaped frame 31. The hook frame 11 is located above the I-shaped frame 31. Push the cabinet body 1 from left to right. The hook claw 5 will first grab and hook on the left side of the I-shaped frame 31. Continue to push the cabinet body 1. At this time, the connecting sleeve 4 is fixed, and the I-shaped frame 31 restricts the downward movement of the hook frame 11. Then the cabinet body 1 will move to the right relative to the connecting sleeve 4, causing the connecting sleeve 4 and the connecting rod 6 to move relative to each other. The first spring 7 is stretched. When the hook frame 11 moves to the right edge of the I-shaped frame 31 and is no longer restricted by the I-shaped frame 31, under the action of the first spring 7, the connecting rod 6 moves to the left, and then the rotating arm 10 is rotated, thereby带动 the moving plate 9 and the hook frame 11 to move downward, making the hook frame 11 block on the right side of the I-shaped frame 31. At this time, stop pushing the cabinet body 1. Under the restoring tendency of the first spring 7, the first spring 7 will apply force to the hook claw 5 and the hook frame 11, so that the relative position between the cabinet body 1 and the I-shaped frame 31 can be fixed in the left-right direction, and the cabinet body 1 can be stably fixed on the I-shaped frame 31.

[0034] Combined with Figure 1 and Figure 6 As shown, the fixing component further includes: a C-shaped block 12 slidably installed on the hook frame 11. The C-shaped block 12 can be snapped into the I-shaped frame 31. The bottom of the C-shaped block 12 is provided with an arc-shaped bottom surface. The C-shaped blocks 12 of the three fixing components are fixed together with a handle, so that the three can be controlled to move uniformly; a second spring 13 fixedly connected between the hook frame 11 and the C-shaped block 12.

[0035] During the downward movement of the hook frame 11, the bottom surface of the C-shaped block 12 will contact the edge of the I-shaped frame 31. Under the action of the arc-shaped bottom surface of the C-shaped block 12, the C-shaped block 12 is squeezed and moves away from the I-shaped frame 31, and the second spring 13 is compressed until the lower part of the C-shaped block 12 passes over the I-shaped frame 31, and the second spring 恢复 and snaps the C-shaped block 12 into the I-shaped frame 31. By providing the C-shaped block 12 to assist the hook frame 11 in grabbing and hooking the I-shaped frame 31, the stability of the connection between the hook frame 11 and the I-shaped frame 31 is improved, and further the fixing effect of the fixing component is improved.

[0036] Combined with Figure 1 and Figure 6 As shown, it further includes: hook plates 14 fixedly installed on the front and rear sides of the bottom of the cabinet body 1. The hook plates 14 are in insertion fit with the frame edges of the I-shaped frame 31. When the cabinet body 1 is placed on the I-shaped frame 31, the hook plates 14 are inserted into both sides of the I-shaped frame 31. As the cabinet body 1 moves, the hook plates 14 and the I-shaped frame 31 gradually move to full fit, and the hook plates 14 and the I-shaped frame 31 restrict the cabinet body 1 in the front-back direction, further improving the stability of the cabinet body 1 fixed on the I-shaped frame 31.

[0037] Combined with Figure 7 and Figure 8As shown, it also includes: a locking assembly arranged in the cabinet 1, and two sets of locking assemblies are arranged in the cabinet 1, and the locking assemblies are also arranged in an independent space at the bottom of the cabinet 1;

[0038] The locking assembly includes: a mounting frame 15 fixedly mounted on the bottom of the cabinet 1; grab plates 16 slidably mounted on the left and right sides of the mounting frame 15, and the two grab plates 16 are respectively arranged on the left and right sides of the steel bar on the I-frame 31; a first tooth 17 fixedly mounted on the grab plate 16; a screw rod 18 rotatably mounted in the cabinet 1, the screw rod 18 cooperates with the first tooth 17, and the rotation of the screw rod 18 controls the grab plate 16 to move along the mounting frame 15 through the first tooth 17; a handle 19 fixedly mounted on the top of one of the screw rods 18; a synchronization assembly 20 installed between two adjacent screw rods 18, and the synchronization assembly 20 causes all the screw rods 18 to rotate synchronously.

[0039] After using the fixing assembly to install the photovoltaic grid-connected cabinet, rotate the screw rod 18 to control the grab plate 16 to pass through the bottom of the cabinet body 1 and move to both sides of the steel bar of the I-frame 31, and rest on both sides of the steel bar. By limiting the relative position between the cabinet body 1 and the I-frame 31 in the left and right directions, it forms a resistance to the operation of the fixing assembly, realizes the locking of the fixing assembly, and further improves the fixing stability of the cabinet body 1.

[0040] Combine Figure 1 、 Figure 9 and Figure 10 As shown, it also includes: a dehumidification and heat dissipation component provided on the cabinet 1, the dehumidification and heat dissipation component is used to select dehumidification or heat dissipation of the interior of the cabinet 1 according to actual conditions;

[0041] The dehumidification and heat dissipation assembly includes: an exhaust fan 21 fixedly mounted on the top of the right side wall of the cabinet 1; an intake pipe 22 fixedly mounted inside the cabinet 1, the intake pipe 22 is connected to and communicated with the exhaust fan 21; a docking frame 23 fixedly mounted on the top of the right wall of the cabinet 1, the docking frame 23 is connected to and communicated with the exhaust fan 21; a dehumidification box 24 fixedly mounted on the docking frame 23; a docking pipe 25 fixedly mounted between the dehumidification box 24 and the cabinet 1, the docking pipe 25 connects the dehumidification box 24 and the cabinet 1; a discharge port is provided at the bottom of the docking frame 23, and a sealing plate 26 is slidably mounted on the bottom of the docking frame 23, the sealing plate 26 closes the discharge port of the docking frame 23; a switching plate 27 rotatably mounted between the docking frame 23 and the dehumidification box 24, the switching plate 27 rotates to control the opening and closing of the dehumidification box 24; a second tooth 28 fixedly mounted on the switching plate 27; a rack 29 fixedly mounted on the sealing plate 26, the rack 29 cooperates with the second tooth 28, and the sealing plate 26 moves to control the rotation of the switching plate 27.

[0042] When it is necessary to dissipate heat inside the cabinet 1, the sealing plate 26 is moved to open the exhaust port, and the switching plate 27 is controlled by the sealing plate 26 to rotate, thereby closing the dehumidification box 24 and starting the exhaust fan 21. The high-temperature gas in the cabinet 1 can be discharged from the cabinet 1 through the suction pipe 22, the exhaust fan 21, the docking frame 23 and the exhaust port in turn. After the above cycle, the purpose of heat dissipation and cooling in the cabinet 1 can be achieved. When it is necessary to dehumidify and prevent moisture in the cabinet 1, the sealing plate 26 is used to close the exhaust port. At the same time, the switching plate 27 is rotated to open the dehumidification box 24, and then the exhaust fan 21 is started. The humid gas in the cabinet 1 will enter the dehumidification box 24 through the suction pipe 22, the exhaust fan 21 and the docking frame 23 in turn, and the dry gas after being processed by the dehumidification box 24 will be transported back to the cabinet 1 through the docking pipe 25. After the above cycle, the purpose of dehumidification and moisture prevention can be achieved. The dehumidification and heat dissipation component will protect the equipment and lines in the cabinet 1, improving the safety of the photovoltaic grid-connected cabinet.
