Description

Technical Field

[0001] The present invention relates to the technical field of energy storage converters, and in particular to a novel grid-type energy storage converter. Background Art

[0002] The role of energy storage system in the power grid includes: providing active or reactive support for the system, improving the grid-connected capacity of new energy, participating in peak load and frequency regulation, short-term power supply during faults, etc.; using network control technology to control energy storage inverters can improve the stability of new power systems; energy storage inverters can control the charging and discharging process of batteries, perform AC / DC conversion, and can directly supply power to AC loads without a power grid; PCS is composed of DC / AC bidirectional inverters, control units, etc. The PCS controller receives background control instructions through communication, and controls the inverter to charge or discharge the battery according to the sign and size of the power instruction, thereby realizing the regulation of active power and reactive power of the power grid. The PCS controller communicates with the BMS through the CAN interface to obtain battery pack status information, which can realize protective charging and discharging of the battery and ensure battery operation safety.

[0003] The existing mesh-type energy storage inverter has ventilation and heat dissipation structures such as heat dissipation slots and heat dissipation nets on the body, which is beneficial to the heat dissipation of components inside the body. However, after long-term use, conventional heat dissipation nets are prone to dust accumulation, which causes the holes to be blocked and affects the heat dissipation. When the outer side of the heat dissipation net is swept by a simple cleaning device, the dust is also easy to float and may enter the body, causing the dust accumulation of the internal components to increase. Therefore, it is necessary to develop a new type of mesh-type energy storage inverter. Summary of the invention

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0045] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] See also Figure 1-Figure 8 , which shows a schematic diagram of a novel grid-type energy storage converter implementation method of the present invention, please refer to Figure 1-Figure 8 , a new type of grid-type energy storage converter is introduced in detail.

[0047] Embodiment 1:

[0048] A new type of grid-forming energy storage converter includes a converter body 100. The converter body 100 includes a body 101 for storing converter-related components, and a heat dissipation net 102 for component heat dissipation is provided on one side of the body 101;

[0049] The dust suction and filtration assembly 200 is movably located outside the heat dissipation net 102, including a dust suction cylinder 201 and protective nets 202 provided on both sides of the dust suction cylinder 201. A first cleaning brush 203 for cleaning the dust on the heat dissipation net 102 is provided on the side of the protective net 202 close to the heat dissipation net 102. An air suction structure for dust suction and a dust filtration net 205 for filtering dust are provided inside the dust suction cylinder 201;

[0050] The dust sweeping assembly 300 is arranged inside the dust suction cylinder 201, including a "卄"-shaped lifting frame 301 that reciprocates up and down. A second cleaning brush 302 for cleaning the dust attached to the surface of the dust filtration net 205 is provided on the rear side of the lifting frame 301. The air suction structure drives the lifting frame 301 to reciprocate up and down synchronously when sucking dust;

[0051] The driving assembly 400 is arranged outside the body 101 near the heat dissipation net 102, and is used to drive the dust suction and filtration assembly 200 to reciprocate horizontally and slowly reciprocate up and down. Here, "slowly" means that when the dust suction and filtration assembly 200 reciprocates up and down, its speed is slower than when it reciprocates horizontally;

[0052] The air suction structure includes a "十"-shaped bracket 204 fixed on the inner side wall of the dust suction cylinder 201. A dust suction motor 206 is provided on the front side of the bracket 204, and a fan blade 207 is provided on the output shaft of the dust suction motor 206. The rotating fan blade 207 continuously sucks the gas inside the body 101 into the dust suction cylinder 201;

[0053] Start the dust suction motor 206 to drive the fan blade 207 to rotate. Since both the fan blade 207 and the protective net 202 are installed on the dust suction cylinder 201, the dust suction cylinder 201 is equivalent to a movable air suction channel. Coupled with the dust suction cylinder 201 moving reciprocally horizontally and slowly reciprocally up and down under the action of the driving assembly 400, the dust suction cylinder 201 can clean the surface of the heat dissipation net 102 area by area, reducing the possibility of the heat dissipation net 102 being blocked by dust. The dust swept down can be sucked into the inside of the dust suction cylinder 201 and filtered through the dust filtration net 205;

[0054] A dust collection box 208 is convexly provided directly in front of and below the bottom of the dust suction cylinder 201, and the inner bottom of the dust collection box 208 is inclined;

[0055] A dust exhaust pipe 209 connected to the inner cavity of the dust box 208 is arranged at the bottom of the dust collecting box 208, and the upper end of the dust exhaust pipe 209 is located at the lowest point of the bottom wall of the dust collecting box 208. A dust exhaust valve 210 for controlling the on / off of the dust exhaust pipe 209 is arranged on the dust exhaust pipe 209. Most of the dust filtered by the dust filter 205 will fall into the dust collecting box 208 at the lower front side thereof. When it is necessary to discharge the dust collected in the dust collecting box 208, after opening the dust exhaust valve 210, since the inner bottom of the dust collecting box 208 is arranged at an angle, the dust is facilitated to flow along the inclined dust collecting box 208 to the dust exhaust pipe 209 and then be discharged.

[0056] Embodiment 2:

[0057] Please refer again Figures 3 to 6 , based on Example 1, the figure shows that: the dust sweeping assembly 300 also includes a first bevel gear 303 arranged at the front end of the output end of the dust suction motor 206, the top of the dust suction cylinder 201 is located in front of the first bevel gear 303 and is rotatably provided with a vertical rotating rod 304, and the lower end of the rotating rod 304 is provided with a second bevel gear 305 meshing with the first bevel gear 303;

[0058] The upper and lower inner side walls of the dust collecting cylinder 201 are located in front of the dust filter 205 and are rotatably provided with a vertical linkage reciprocating screw rod 306. The upper ends of the linkage reciprocating screw rod 306 and the rotating rod 304 are respectively provided with sprocket wheels 307. The two sprocket wheels 307 are linked by a chain 308.

[0059] The upper and lower inner side walls of the dust collection cylinder 201 are fixedly provided with a vertical guide rod 309 on the left side in front of the dust filter 205;

[0060] The rod body of the linked reciprocating screw rod 306 is transmitted through the right end of the lifting frame 301, and the rod body of the guide rod 309 slides through the left end of the lifting frame 301; when the suction structure is working, the output shaft of the dust suction motor 206 also drives the first bevel gear 303 to rotate, and then drives the rotating rod 304 and the sprocket 307 on its top to rotate through the second bevel gear 305, and then drives another sprocket 307 and the linked reciprocating screw rod 306 to rotate through the chain 308, thereby driving the lifting frame 301 to reciprocate and lift along the rod body of the linked reciprocating screw rod 306 and the guide rod 309, that is, the dust on the surface of the dust filter 205 can be continuously and reciprocated by the second cleaning brush 302. It should be noted that during the lifting process of the lifting frame 301, there is always a gap between it and the sprocket 307, chain 308 and other components, and the lifting frame 301 passes through the inner side of the chain 308.

[0061] Embodiment 3:

[0062] Please refer again Figure 5 and Figure 6, on the basis of Embodiment 2, as shown in the figure: the front and rear inner side walls of the dust suction cylinder 201 are recessed to form a first embedded groove 310 for the embedded installation of the linkage reciprocating lead screw 306 and the guide rod 309; through the opened first embedded groove 310, the guide rod 309 and the linkage reciprocating lead screw 306 are respectively embedded on the left and right sides in front of the dust filter net 205, and the guide rod 309 and the linkage reciprocating lead screw 306 will not block the dust sucked by the dust filter net 205;

[0063] The upper part of the inner side wall of the dust suction cylinder 201 is provided with an obliquely arranged second embedded groove 311 for the embedded installation of the sprocket 307 and the chain 308, and the sprocket 307 and the chain 308 are located above the dust filter net 205; through the opened second embedded groove 311, the sprocket 307 and the chain 308 will not block the rear of the dust filter net 205 and affect the air flow;

[0064] The thickness of the lifting frame 301 is the same as the groove width of the first embedded groove 310, and the inner side wall of the first embedded groove 310 is smooth and fits with the outer side wall of the lifting frame 301;

[0065] The length of the upper and lower ends of the lifting frame 301 is at least twice the vertical height inside the first embedded groove 310, and the upper and lower inner side walls of the first embedded groove 310 are provided with through holes 312 for the upper and lower ends of the lifting frame 301 to fit and slide through; since the length of the upper and lower ends of the lifting frame 301 is at least twice the vertical height inside the first embedded groove 310, and the thickness of the lifting frame 301 is the same as the groove width of the first embedded groove 310, the lifting frame 301 can keep the linkage reciprocating lead screw 306 and the guide rod 309 respectively "enclosed" in the two first embedded grooves 310 during the lifting process, so as to reduce the entry of dust into the first embedded groove 310 and affect the rotation of the linkage reciprocating lead screw 306.

[0066] Embodiment 4:

[0067] Please refer to again Figures 6 to 8 , on the basis of Embodiment 1, as shown in the figure: the driving assembly 400 includes a "冂"-shaped mounting frame 401 fixed on the rear side wall of the machine body 101, two vertical sliding grooves 402 are symmetrically arranged on the left and right sides at the rear of the mounting frame 401, a vertical reciprocating lead screw 403 is rotatably arranged in each sliding groove 402, and a lifting block 404 is arranged in the sliding groove 402 in a lifting and sliding manner, and the rod body of the vertical reciprocating lead screw 403 is传动贯穿 the lifting block 404; when the vertical reciprocating lead screw 403 rotates, it will drive the lifting block 404 to reciprocate up and down;

[0068] It should be noted that there may be an incorrect expression "传动贯穿" in the original text. It might be a misspelling. If it is corrected to "传动穿过", the translation of this part will be more accurate: when the vertical reciprocating lead screw 403 rotates, it will drive the lifting block 404 to reciprocate up and down by passing through the lifting block 404.The rear ends of the two lifting blocks 404 protrude from the slide slot 402, and a fixing frame 405 is fixedly arranged between the side walls of the two lifting blocks 404. A transverse reciprocating screw rod 406 is rotatably arranged between the left and right inner side walls of the fixing frame 405, and a transverse limiting rod 407 is fixedly arranged. A transverse moving block 408 located on the inner side of the fixing frame 405 is fixedly arranged protruding from the bottom of the dust collection cylinder 201. The rod body of the transverse reciprocating screw rod 406 transmits and penetrates the side wall of the transverse moving block 408, and the rod body of the limiting rod 407 slides and penetrates the side wall of the transverse moving block 408. When the transverse reciprocating screw rod 406 rotates, it drives the transverse moving block 408 to move back and forth transversely along the transverse reciprocating screw rod 406 and the limiting rod 407.

[0069] The driving assembly 400 further includes a servo motor 409 fixed to the rear side wall of the left lifting block 404. The inner cavity of the left lifting block 404 is provided with a mounting cavity 410. The output shaft of the servo motor 409 rotates and penetrates the inner wall of the mounting cavity 410 and is fixedly provided with a first worm 411. One end of the transverse reciprocating screw rod 406 rotates and penetrates the inner wall of the mounting cavity 410 through a bearing sleeve and is provided with a first worm wheel 412 meshing with the first worm wheel 411. After the servo motor 409 is started, the transverse reciprocating screw rod 406 is rotated through the first worm wheel 411 and the first worm wheel 412.

[0070] The output shaft of the servo motor 409 is also provided with a second worm 413. The upper and lower walls of the left lifting block 404 are provided with a vertical spline sleeve 414 through which the bearing sleeve rotates. The outer side of the spline sleeve 414 is provided with a second worm wheel 415 that meshes with the second worm 413. A fixing plate 416 is fixedly provided at the upper left corner of the rear side wall of the installation frame 401. The lower end of the fixing plate 416 is provided with a vertical spline rod 417 through a bearing seat. The adaptor transmission penetrates the inner side of the spline sleeve 414. When the spline sleeve 414 rotates, the spline rod 417 can be driven to rotate. When the spline sleeve 414 is lifted or lowered, it can also be lifted or lowered along the shaft of the spline rod 417. After the servo motor 409 is started, the second worm 413 and the second worm wheel 415 can drive the spline sleeve 414 and the spline rod 417 to rotate. When the spline sleeve 414 is lifted or lowered, the spline sleeve 414 can also be lifted or lowered along the shaft of the spline rod 417.

[0071] The rear side wall of the body 101 is provided with a storage shell 418 below the left lifting block 404, and the interior of the storage shell 418 is provided with a reduction gear set structure. When the spline rod 417 rotates, it is decelerated by the reduction gear set structure and then drives a vertical reciprocating screw rod 403 to rotate; because when the transverse block 408 moves back and forth laterally, it drives the dust collection and filtering assembly 200 to perform the dust sweeping and dust absorption processes, if the vertical reciprocating screw rod 403 is driven to rotate directly by the spline rod 417, the rotation speed of the vertical reciprocating screw rod 403 will be too fast, thereby causing the lifting speed of the lifting block 404 and the dust collection and filtering assembly 200 to be too fast, so that the upper and lower spacing of the heat dissipation network 102 area cleaned by the dust collection and filtering assembly 200 is large, and there may be missed areas, so a reduction gear set structure is provided.

[0072] Embodiment 5:

[0073] Please refer again Figure 8 , based on Example 4, the figure shows: the reduction gear set structure includes a first mounting plate 419 fixed inside the storage shell 418, and a first transmission gear 420 is rotatably arranged on the first mounting plate 419 directly below the spline rod 417, and the lower end of the spline rod 417 rotates through the first mounting plate 419 through the bearing sleeve and is connected to the top center of the first transmission gear 420, and a second transmission gear 421 meshing with the first transmission gear 420 is also rotatably arranged on the first mounting plate 419, and the diameter of the second transmission gear 421 is larger than the diameter of the first transmission gear 420;

[0074] A third transmission gear 422 having a smaller diameter than the second transmission gear 421 is disposed at the lower end center of the second transmission gear 421;

[0075] A second mounting plate 423 is fixedly arranged inside the storage shell 418 below the vertical reciprocating screw rod 403 and the third transmission gear 422.
