DETAILED DESCRIPTION

[0027] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] like Figure 1-Figure 7As shown, the present invention provides a technical solution: a cabinet-type active filter, comprising a cabinet body 1 and a module reinforcement component 5, wherein vertical panels 2 are arranged on both sides of the interior of the cabinet body 1, and sliding guide rails 3 are fixed equidistantly on the inner side of the vertical panel 2, and an active filter module body 4 is arranged inside the sliding guide rail 3, and the module reinforcement component 5 is arranged on both sides of the surface of the vertical panel 2 and the surface of the active filter module body 4, and the module reinforcement component 5 comprises a first insulating box 501, a first electromagnet end 502, a rotating shaft 503, a locking member 504, a first homosexual sheet 505, a second homosexual sheet 506, a second insulating box 507 and a second electromagnet end 508, the first electromagnet end 502 is fixed at the end of the first insulating box 501, and a rotating shaft 503 is arranged on one side of the first insulating box 501, and a locking member 504 is fixed on the outer wall of the rotating shaft 503, and the locking member 504 is close to the first A first homosexual piece 505 is fixed to one side of an insulating box 501, a second homosexual piece 506 is fixed to one side of a locking member 504 away from the first insulating box 501, and a second insulating box 507 is arranged on the side of the second homosexual piece 506, a second electromagnet end 508 is fixed to the end of the second insulating box 507, a handle 6 is fixed to the middle of both sides of the surface of the active filter module body 4, a rotating shaft 503 is rotatably connected to the surface of the vertical panel 2, and the locking member 504 is rotatably connected to the surface of the vertical panel 2 through the rotating shaft 503, the second insulating box 507 is fixed to the surface of the active filter module body 4, and the second insulating boxes 507 are symmetrically distributed about the central axis of the active filter module body 4, the second electromagnet end 508, the second homosexual piece 506, the first homosexual piece 505, and the first electromagnet end 502 are on the same arc line, and the arc line takes the rotating shaft 503 as the center;

[0029] The specific operation is as follows: during installation, the active filter module body 4 is manually lifted and inserted into the sliding guide rail 3 and pushed, so that the face part of the active filter module body 4 is flush with the surface of the vertical panel 2. At this time, the rear end of the active filter module body 4 must be against the inner wall of the sliding guide rail 3 and can no longer slide freely. Then, the active filter module body 4 can be automatically reinforced by the module reinforcement component 5;

[0030] Specifically, the first electromagnet end 502 on the surface of the vertical panel 2 is energized to repel the first isotropic sheet 505. The first isotropic sheet 505 and the second isotropic sheet 506 are magnets. The first electromagnet end 502 and the second electromagnet end 508 are located inside the first insulating box 501 and the second insulating box 507, respectively, with only the end faces exposed to prevent leakage.

[0031] When the first like-sex pieces 505 repel each other, they carry the locking piece 504 to rotate through the rotating shaft 503 based on the repulsive force, so that the locking piece 504 spans the surface of the vertical panel 2 and the surface of the active filter module body 4, thereby reinforcing the active filter module body 4 to prevent it from sliding. At this time, the second electromagnet end 508 is not energized so that the rotated locking piece 504 abuts against the end face of the second electromagnet end 508 with its side, so as to prevent the locking piece 504 from excessively rotating or being unable to span the surface of the vertical panel 2 and the surface of the active filter module body 4 due to gravity.

[0032] When the active filter module body 4 needs to be extracted, it is only necessary to control the second electromagnet end 508 to be energized while the first electromagnet end 502 remains in an off state. At this time, the second electromagnet end 508 and the second homosexual piece 506 repel each other with the same polarity, so that the second homosexual piece 506 carries the locking member 504 to rotate through the rotating shaft 503 based on the repulsive force, so that the locking member 504 rotates in the opposite direction to reset, thereby releasing the reinforcement of the active filter module body 4. At this time, the active filter module body 4 can be removed by manually holding the handle 6 and pulling it.

[0033] Based on the above description, the present invention controls the power-on and power-off states of the first electromagnet end 502 and the second electromagnet end 508 to make the first homosexual piece 505 or the second homosexual piece 506 carry the locking member 504 to rotate counterclockwise or clockwise under the action of like-sex repulsion, and uses the first electromagnet end 502 and the second electromagnet end 508 to limit the rotation angle of the locking member 504 to achieve automatic reinforcement and automatic release of the active filter module body 4. Compared with the existing method of manually tightening a number of screws to reinforce or disassemble the active filter module body 4, the stability of the active filter module body 4 after installation is ensured while greatly reducing the complexity of disassembly and assembly.

[0034] like Figure 1-Figure 7As shown, a through groove 7 is provided on the surface of the vertical panel 2 on one side of the first insulating box 501, and an auxiliary loading and unloading assembly 8 is provided on the side of the vertical panel 2 facing the inside of the cabinet body 1, and the auxiliary loading and unloading assembly 8 includes a driving motor 801, a first bevel gear 802 and a second bevel gear 803, the output end of the driving motor 801 is connected to the first bevel gear 802, and the bottom of the first bevel gear 802 is meshedly connected to the second bevel gear 803, the auxiliary loading and unloading assembly 8 also includes a screw rod 804 and a movable sleeve seat 805, the middle part of the second bevel gear 803 is fixed with a screw rod 804, and the screw rod 804 is fixed to the middle part of the second bevel gear 803. 04 is provided with a movable sleeve seat 805 on the outer wall, the auxiliary loading and unloading assembly 8 also includes a lifting support rod 806, the outer wall of the movable sleeve seat 805 is fixed with a lifting support rod 806, the auxiliary loading and unloading assembly 8 also includes a support plate 807, the outer end of the lifting support rod 806 passes through the through slot 7 and is fixed with the support plate 807, and the spacing between the support plate 807 and the surface of the active filter module body 4 is greater than the spacing between the outer surface of the handle 6 and the surface of the active filter module body 4, one side of the cabinet body 1 is connected to a cabinet door 9 by a hinge, and an opening and closing sensor is provided on the inner side of the cabinet door 9;

[0035] The specific operation is as follows: the opening and closing sensor is a pressure sensor to monitor the opening and closing state of the cabinet door 9. When the system background manually issues a command to disassemble the active filter module body 4, when it is detected that the cabinet door 9 is opened, the control system automatically energizes the second electromagnet end 508 to realize the release of the active filter module body 4, so that the personnel can immediately remove the active filter module body 4 after opening the cabinet door 9;

[0036] When disassembling and assembling the active filter module body 4, due to its volume and weight and to prevent bumping, it needs to be handled with care, so it is often necessary for two people to lift or remove it. However, the auxiliary loading and unloading assembly 8 of the present invention can realize the disassembly and assembly and placement operation by one person. Specifically, when installing the active filter module body 4, its rear end is mounted on the surface of the support plate 807, and the first bevel gear 802 is driven by the driving motor 801 to rotate to drive the second bevel gear 803 to rotate synchronously. The second bevel gear 803 will drive the screw rod 804 to rotate, so that the movable sleeve 805 carries The lifting support rod 806, the support plate 807 and the active filter module body 4 on the surface thereof are raised. At this time, only one person needs to hold the panel part of the active filter module body 4 to lift it. After the active filter module body 4 reaches the specified height, it is manually pushed so that its rear end enters the interior of the sliding guide rail 3. After it is determined that the rear end of the active filter module body 4 enters a part of the interior of the sliding guide rail 3, the screw rod 804 rotates in the opposite direction to make the support plate 807 descend, and then the personnel push the active filter module body 4 until its surface is flush with the surface of the vertical panel 2;

[0037] When the active filter module body 4 needs to be removed, the active filter module body 4 only needs to be pulled outwards to make its panel part exceed the position of the support plate 807, and then the support plate 807 is raised to make its panel stick to the bottom surface of the active filter module body 4, and then the active filter module body 4 is continued to be pulled outwards to make its rear end bottom surface mounted on the surface of the support plate 807, and then the active filter module body 4 can be stably removed by holding the panel part of the support plate 807 and coordinating the support plate 807 to descend;

[0038] Based on the above description, the present invention utilizes the lifting and lowering of the support plate 807 in conjunction with manual operation by personnel so that the active filter module body 4 can be lifted and lowered smoothly, so that a single person can complete the lifting and removal of the active filter module body 4, thereby greatly simplifying the disassembly and assembly process of the active filter module body 4 and the number of personnel required.

[0039] In summary, when the cabinet-type active filter is used, first, the active filter module body 4 is manually lifted and inserted into the sliding guide rail 3 and pushed during installation, so that the face part of the active filter module body 4 is flush with the surface of the vertical panel 2. At this time, the rear end of the active filter module body 4 must be against the inner wall of the sliding guide rail 3 and can no longer slide at will, and then the active filter module body 4 can be automatically reinforced by the module reinforcement component 5;

[0040] When the first like-sex pieces 505 repel each other, they carry the locking piece 504 to rotate through the rotating shaft 503 based on the repulsive force, so that the locking piece 504 spans the surface of the vertical panel 2 and the surface of the active filter module body 4, thereby reinforcing the active filter module body 4 to prevent it from sliding. At this time, the second electromagnet end 508 is not energized so that the rotated locking piece 504 abuts against the end face of the second electromagnet end 508 with its side, so as to prevent the locking piece 504 from excessively rotating or being unable to span the surface of the vertical panel 2 and the surface of the active filter module body 4 due to gravity.

[0041] When the active filter module body 4 needs to be extracted, it is only necessary to control the second electromagnet end 508 to be energized while the first electromagnet end 502 remains in an off state. At this time, the second electromagnet end 508 and the second homosexual piece 506 repel each other with the same polarity, so that the second homosexual piece 506 carries the locking member 504 to rotate through the rotating shaft 503 based on the repulsive force, so that the locking member 504 rotates in the opposite direction to reset, thereby releasing the reinforcement of the active filter module body 4. At this time, the active filter module body 4 can be removed by manually holding the handle 6 and pulling it.

[0042] When installing the active filter module body 4, its rear end is mounted on the surface of the support plate 807, and the first bevel gear 802 is driven to rotate by the driving motor 801 to carry the second bevel gear 803 to rotate synchronously, and the second bevel gear 803 will drive the screw rod 804 to rotate, so that the movable sleeve 805 carries the lifting support rod 806, the support plate 807 and the active filter module body 4 on its surface to rise. At this time, only one person needs to hold the panel part of the active filter module body 4 to lift it. After the active filter module body 4 reaches the specified height, it is manually pushed to make its rear end enter the inside of the sliding guide rail 3. After determining that the rear end of the active filter module body 4 enters a part of the inside of the sliding guide rail 3, the screw rod 804 rotates in the opposite direction to make the support plate 807 descend, and then the active filter module body 4 is pushed by personnel until its surface is flush with the surface of the vertical panel 2;

[0043] When the active filter module body 4 needs to be removed, it is only necessary to first pull out the active filter module body 4 so that its panel portion exceeds the position of the support plate 807, and then the support plate 807 rises so that its panel is attached to the bottom surface of the active filter module body 4, and then the active filter module body 4 is continued to be pulled out so that its rear end bottom surface is mounted on the surface of the support plate 807, and then the active filter module body 4 can be stably removed by only holding the panel portion of the support plate 807 and coordinating the support plate 807 to descend.

Many modifications and variations will be apparent to those of ordinary skill in the art.
