Description

Technical Field

[0001] This invention relates to the field of frequency converter cabinet technology, and in particular to a frequency converter cabinet. Background Technology

[0002] Currently, my country's technology in the application of frequency converters is becoming increasingly mature, and frequency converter cabinets used for storage and protection are becoming increasingly important. Traditional frequency converter cabinets are equipped with receiving plates for placing various electrical control components. These receiving plates are welded to the housing or directly fixed to the housing using threaded fasteners. Using non-removable welded structures or cabinet structures that are difficult to disassemble, mounting holes for electrical control components must be pre-drilled during cabinet production. During frequency converter assembly, these components are installed in the pre-drilled holes. Due to the cabinet structure limitations, the mounting surface is generally not facing outwards, requiring assembly personnel to reach into the cabinet for installation. The operating space is relatively narrow, with components arranged on the left, right, and front, resulting in a small viewing angle. Existing frequency converter cabinets rarely have dedicated frequency converter cabinets, failing to provide visual assistance in the confined space inside. Furthermore, due to space constraints, only one assembly worker can operate the installation of components and wiring. If lighting is required during component installation and replacement, it increases the difficulty of the work, wastes time, and hinders the rapid completion of the work.

[0003] Therefore, existing lighting in inverter cabinets either provides no illumination or has a limited illumination area, easily creating shadows. This makes it difficult to quickly locate fault points during inverter maintenance, installation, and commissioning. In dark environments, fault points that should be noticeable are easily overlooked, creating potential safety hazards. Furthermore, existing lights occupy too much space inside the inverter cabinet and generate significant heat during operation, hindering inverter heat dissipation and impacting inverter efficiency.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1

[0035] Reference Figures 1-2 This is the first embodiment of the present invention, which provides a frequency converter cabinet that can facilitate installation and commissioning within the frequency converter cabinet, and includes a frequency converter cabinet.

[0036] Specifically, the main structure 100 includes a cabinet 101, a heat dissipation hole 102 opened on the cabinet wall of the cabinet 101, a cabinet door 103 set on the outside of the cabinet 101, a cabinet top 104 set on the top of the cabinet 101, and a support member 105 set on the bottom of the cabinet 101, wherein a sliding groove 106 is opened on one side of the cabinet door 103.

[0037] Furthermore, the cabinet 101 has two cabinet doors 103 at the front and back, and the heat dissipation holes 102 are circular and are respectively opened on the surface of the cabinet wall on both sides where the lighting mechanism 200 is installed. The support member 105 has a slot at the bottom.

[0038] The cabinet door 103 is provided on both the front and back sides of the cabinet body 101, which facilitates the operation of the inverter from the front and the wiring work from the back, reducing the trouble of disassembling the cabinet wall. The inverter generally has a large power and requires heat dissipation. Therefore, multiple heat dissipation holes 102 are opened proportionally on both sides of the cabinet body to facilitate the heat dissipation of the inverter. At the same time, the top of the cabinet 104 provides a certain degree of protection for the inverter cabinet, and the support member 105 at the bottom provides support for the cabinet body 101. Meanwhile, the empty groove at the bottom allows the cabinet body 101 to be loaded into a trolley or other object for easy transportation.

[0039] Specifically, the cabinet door 103 includes a heat dissipation vent 103a on the surface of the cabinet door 103, a door handle 103b at the bottom of the heat dissipation vent 103a, a switch control component 103c at the bottom of the door handle 103b, and a hinge 103d at the connection of the cabinet door 103.

[0040] Furthermore, the switch control component 103c includes a pin 103c-1 disposed at the bottom of the door handle 103b, a switch 103c-2 disposed at the bottom of the pin 103c-1, a return spring 103c-3 disposed at the bottom of the switch 103c-2, and a wire 103c-4 disposed at the bottom of the switch 103c-2.

[0041] The heat dissipation vents 103a on the surfaces of the two cabinet doors 103 are opposite each other, which can form airflow to facilitate the heat dissipation of the frequency converter. The door handle 103b is designed in a folding mode, which can be pulled out from the door handle frame and then rotated to facilitate the opening of the cabinet door 103. At the same time, a switch controller 103c is provided on the inside of the cabinet door 103. Its pin 103c-1 is connected to the switch 103c-2 of the lighting panel 204. When the door is closed, the pin 103c-1 presses the switch 103c-2, and the switch is open. When the pin 103c-1 is opened, the switch 103c-2 is automatically closed under the action of the return spring 103c-3, and the wire 103c-4 is connected, so that the lighting panel 204 can work.

[0042] Preferably, the hinge between the cabinet door 103 and the cabinet body 101 is a hinge 103d. This hinge 103d has a large mechanical potential energy, so that the cabinet door 103 can close without interference after being opened, which is convenient for staff to inspect and maintain.

[0043] When in use, opening the cabinet door 103 causes the door lock inside the door handle 103b to press against the switch of the lighting panel 204, activating the lighting panel 204 and providing light to the inside of the inverter cabinet. When the cabinet door 103 is closed, the door lock presses against the switch of the lighting panel 204, turning off the lighting panel 204 and no longer providing light, thus saving energy.

[0044] In summary, cabinet 101 provides a suitable location for the inverter to be easily maintained and installed, has good heat dissipation performance, can provide lighting during maintenance, installation and commissioning, and automatically turns off after maintenance is completed.

[0045] Example 2

[0046] Reference Figures 2-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a lighting mechanism and a transmission mechanism for the inverter cabinet, which solves the problem of insufficient lighting inside the inverter.

[0047] Specifically, the lighting mechanism 200 is located inside the cabinet 101 and includes a mounting groove 201 on the inner wall of the cabinet 101 near the top, a connecting wire 202 at the bottom of the mounting groove 201, a retractable wire 203 in the middle of the connecting wire 202, and a lighting panel 204 on one side of the retractable wire 203.

[0048] Furthermore, the bottom end of the mounting groove 201 is provided with a slot 201a, and the bottom end of the slot 201a is provided with a through hole 201b, wherein the connecting wire 202 cooperates with the through hole 201b, and the shrink wire 203 is connected to the lighting panel 204 through the through hole 201b.

[0049] The lighting panel 204 includes a fixed plate 204a on one side of the retraction line 203, a lighting lamp 204b on the top of the fixed plate 204a, and soft brushes 204c on both sides of the fixed plate 204a. The fixed plate 204a is movably connected to the lighting lamp 204b, and the fixed plate 204a has a wire interface to provide power to the lighting lamp 204b. When the lighting lamp 204b needs to be replaced, it can be removed from the fixed plate 204a for easy maintenance. The soft brushes 204c on both sides of the fixed plate 204a can clean the heat dissipation holes 102 on both sides of the cabinet to ensure that the heat dissipation holes 102 are unobstructed and achieve better heat dissipation.

[0050] Specifically, the transmission mechanism 300, located in the mounting groove 201, includes an active rod 301 disposed in the sliding groove 106, a transmission rod 302 disposed at the bottom of the active rod 301, a straight rod 303 disposed at the top of the transmission rod 302, a fan-shaped rod 304 disposed at the top of the straight rod 303, a double-layer transmission rod 305 disposed at the bottom of the fan-shaped rod 304, and a direction control component 306 and a height control component 307 disposed at the bottom of the double-layer transmission rod 305, wherein the double-layer transmission rod 305 is disposed in the slot 201a.

[0051] Furthermore, the drive rod 301 is movably connected to the transmission rod 302. The transmission rod 302 can rotate around the tail end of the drive rod 301. The straight rod 303 is fixedly connected to the bottom end of the transmission rod 302, and the top end of the straight rod 303 is movably connected to the limiting groove opened at the tail end of the sector rod 304. The tail end of the sector rod 304 is a straight rod with a limiting groove, and the top end is a sector-shaped gear plate that engages with the rack of the lower layer of the double-layer transmission rod 305.

[0052] When in use, the cabinet door 103 is opened, and the active rod 301 installed at the top of the cabinet door 103 moves with the cabinet door, driving the transmission rod 302 to rotate. A straight rod 303 is fixedly connected to the top surface of the bottom end of the transmission rod 302, and the straight rod 303 is set in the limiting groove opened at the bottom end of the fan-shaped rod 304. The rotation of the fan-shaped surface at the bottom end of the fan-shaped rod drives the double-layer transmission rod 305 to rotate, while controlling the direction control component 306 and the height control component 307, so as to achieve the function of opening the door to lower the lighting panel 204 and closing the door to retract the lighting panel 204.

[0053] In summary, the lighting panel 204 can be raised or lowered as needed through the transmission components. During the raising and lowering process, the heat dissipation holes 102 on the outer wall of the cabinet 101 can be cleaned to enhance the heat dissipation capacity of the frequency converter cabinet.

[0054] Example 3

[0055] Reference Figures 6-8 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a frequency converter cabinet, which solves the problem of controlling the retraction and turning of the lighting panel.

[0056] Specifically, the direction control component 306 includes a first helical gear 306a disposed on one side of the top of the double-layer transmission rod 305, a second helical gear 306b disposed on one side of the first helical gear 306a, a stabilizing rod 306c disposed at the bottom of the second helical gear 306b, a rotating block 306d disposed on the outer wall of the stabilizing rod 306c, and a locking plate 306e disposed on the top surface of the rotating block 306d. The connecting wire 202 is engaged with the locking plate 306e, and when the locking plate 306e rotates, it can drive the connecting wire 202 to rotate together.

[0057] Furthermore, two directional control components 306 are provided on the left and right sides in the mounting groove 201 and are connected by a stabilizer rod 306c. The outer surface of the connecting wire 202 is a connecting rope, and the inner side is equipped with wires, which can provide power to the lighting lamp 204b while ensuring the lighting panel 204 is fixed.

[0058] Specifically, the height control component 307 includes a gear 307a disposed on one side of the bottom end of the double-layer transmission rod 305, a take-up reel 307b disposed on one side of the gear 307a, a support rod 307c disposed in the take-up reel 307b, and a support frame 307d disposed on one side of the support rod 307c, wherein the take-up line 203 cooperates with the take-up reel 307b.

[0059] Furthermore, two height control components 307 are provided on the left and right sides in the mounting groove 201 and are connected by a retraction line 203. When the retraction line 203 on one side retracts into the take-up reel 307b, the take-up reel 307b on the other side will also take in the line at the same time, causing the lighting panel 204 to fold upwards, thus achieving the retraction effect.

[0060] In use, the cabinet door 103 is opened and the lighting switch 204b is turned on. Under the action of the transmission mechanism 300, the double-layer transmission rod 305 simultaneously controls the direction control component 306 and the height control component 307. The upper layer of the double-layer transmission rod 305 pushes the first helical gear 306a to rotate, which drives the second helical gear 306b to rotate, and at the same time drives the stabilizing rod 306c to rotate. The two stabilizing rods 306c rotate and keep the rotating block 306d stable. The locking plate 306e set on the top surface of the rotating block 306d drives the connecting wire 202 to rotate, thereby controlling the rotation of the lighting panel 204. The lower layer of the double-layer transmission rod 305 pushes the gear 307a, which drives the take-up reel 307b to rotate, unfolding the coiled wire 203 collected in the take-up reel 307b, so that the lighting panel 204 unfolds and provides lighting for the entire cabinet 101.

[0061] Preferably, after closing the cabinet door 103, the switch of the light 204b is turned off, and the above operation is repeated in the opposite direction to restore the lighting panel 204 to its original position and fold it up, without occupying the space inside the cabinet or blocking the heat dissipation holes 102 on the outer wall of the cabinet 101.

[0062] In summary, opening the cabinet door 103 allows the lighting panel 204 to be lowered to provide lighting inside the cabinet 101, while closing the cabinet door 103 allows the lighting panel 204 to be retracted to turn off the lighting, and also facilitates heat dissipation inside the cabinet.
