Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and more specifically, to an intelligent power distribution cabinet with a humidity detection device and a temperature control monitoring device. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in the occasions where the load is relatively dispersed and there are fewer circuits; the motor control center is used in the occasions where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] For example, the invention with authorization announcement number CN111969436A discloses an intelligent distribution cabinet, which realizes linkage between the automatic drainage mechanism and the installation frame, and can be triggered as long as the accumulated water inside the distribution cabinet exceeds a certain depth. It utilizes the siphon principle and can continuously discharge all the rainwater inside the cabinet. However, the water still flows into the interior of the distribution cabinet, which easily causes moisture inside the distribution cabinet. Moreover, when the distribution cabinet is in a water-accumulated area, the water flows into the box and cannot be discharged, which easily causes damage to the interior of the distribution cabinet. Summary of the invention

[0014] The beneficial effects of the present invention are as follows: when there is too much water on the ground, the cylinder is turned on to drive the telescopic rod to extend and retract, so that the mounting block on the telescopic rod moves. When the mounting block moves, the connecting plate is driven to move by the first connecting column, and the connecting plate drives the linkage block to slide in the transverse groove through the second connecting column connected by rotation, so that the third connecting column on the linkage block moves. Since the third connecting column is rotatably connected to the first lifting plate, and the first lifting plate is rotatably connected to the center column, when the third connecting column moves, the center column is driven to move through the first lifting plate, and since the center column is rotatably connected to the second lifting plate, and the second lifting plate is rotatably connected in the transverse groove through the mounting column, when When the center column moves, the second lifting plate and the first lifting plate are driven to move closer. Since a connecting block is installed on the center column and the connecting block is slidably connected in the bottom groove at the bottom of the cabinet, when the center column moves, the connecting block is driven to slide in the bottom groove, thereby causing the cabinet to rise. Since sliders are installed at the lower ends of both ends of the cabinet and the sliders are slidably connected in the second vertical grooves, when the cabinet rises, the sliding connection between the sliders and the second vertical grooves can increase the stability of the cabinet rise. The present invention provides a lifting mechanism, and when the cabinet is in a waterlogged place, the cabinet can be lifted away from the water, thereby preventing the water from flowing into the interior of the cabinet and causing damage to the interior of the cabinet.

[0015] When it rains, the motor is turned on by control to drive the rotating shaft to rotate, so that the main gear on the rotating shaft rotates, and the main gear drives the connecting shaft to rotate at the same time by meshing with the driven gear, so that the linkage plate on the rotating shaft and the connecting shaft rotates. Since a through groove is provided on the linkage plate, and a cylinder is slidably connected in the through groove, when the linkage plate rotates, the cylinder is driven to slide in the through groove. Since a mounting plate is installed on the cylinder, a baffle is installed at the bottom of the mounting plate, and slide plates are installed on both sides of the baffle close to one end of the cabinet, and the slide plates are slidably connected in the first vertical groove, when the cylinder slides in the through groove, the baffle is driven to move through the mounting plate, and the baffle is slidably connected to the first vertical groove through the slide plate, and slides on the side wall of the cabinet, thereby blocking the heat dissipation holes provided on both sides of the cabinet to prevent rainwater from entering the cabinet through the heat dissipation holes;

[0016] When the heat dissipation holes are too dirty, the baffle is moved to the heat dissipation holes through the rain shield mechanism, and then the pull block is pulled to make the slide bar on the pull block slide back and forth in the through hole at the center of the baffle. Since a moving plate is installed on the slide bar, and a number of brushes are installed on the moving plate, when the slide bar slides back and forth, it drives the moving plate to reciprocate, so that the brushes on the moving plate clean the heat dissipation holes.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0026] Embodiment 1:

[0027] like Figure 1-4 As shown, an intelligent power distribution cabinet with a humidity detection device and a temperature control monitoring device comprises a cabinet 1, a temperature monitor 2 and a humidity detector 3 are installed at the front end of the cabinet 1, heat dissipation holes 6 are opened on both sides of the cabinet 1, and first vertical grooves 7 with mirror distribution are opened on both sides of the cabinet 1, a rain shielding mechanism 9 is installed on the cabinet 1, and a cleaning mechanism 10 is installed on the rain shielding mechanism 9, and a collection box 8 is fixedly installed on the lower end of both sides of the cabinet 1, and bottom grooves 17 are opened on both sides of the bottom of the cabinet 1, a base 4 is connected to the bottom of the cabinet 1, and a lifting mechanism 5 is connected between the base 4 and the cabinet 1, a groove 15 is opened on one side of the bottom of the base 4, and a transverse groove 16 is opened at the center of the top of the base 4, and the groove 15 and the transverse groove 16 are connected;

[0028] The lifting mechanism 5 includes a cylinder 501, which is fixedly installed in the groove 15. The output end of the cylinder 501 is fixedly connected with a telescopic rod 502. The end of the telescopic rod 502 away from the cylinder 501 is fixedly installed with a mounting block 503. The mounting block 503 is fixedly installed with a first connecting column 504. Two connecting plates 505 are rotatably connected to the outer ring surface of the first connecting column 504. The ends of the connecting plates 505 away from the first connecting column 504 are both rotatably connected with second connecting columns 506. The second connecting columns 506 are fixedly installed with linkage blocks 507. The linkage blocks 507 are all slidably connected in the transverse groove 16. When the cylinder 501 is opened and the mounting block 503 is driven to move by the telescopic rod 502, the mounting block 503 drives the linkage block 507 to slide in the transverse groove 16 through the first connecting column 504, the connecting plate 505 and the second connecting column 506.

[0029] The end of the linkage block 507 away from the second connecting column 506 is fixedly installed with a third connecting column 508, and the third connecting column 508 is rotatably connected to the first lifting plate 509, and the end of the first lifting plate 509 away from the third connecting column 508 is rotatably connected to the center column 510, and the center column 510 is rotatably connected to the second lifting plate 511, and the end of the second lifting plate 511 away from the center column 510 is fixedly installed with a mounting column 513, and both ends of the mounting column 513 are rotatably connected in the transverse groove 16. When the linkage block 507 slides in the transverse groove 16, the first lifting plate 509 and the second lifting plate 511 are driven to approach each other through the third connecting column 508 and the mounting column 513, so that the center column 510 between the first lifting plate 509 and the second lifting plate 511 is raised;

[0030] The central column 510 is fixedly mounted with a connecting block 512, and the connecting block 512 is slidably connected in the bottom groove 17. When the central column 510 rises, the connecting block 512 is driven to slide in the bottom groove 17, thereby raising the cabinet 1.

[0031] A second vertical groove 13 is opened at the center of both sides of the inner wall of the base 4, and a slider 14 is slidably connected in the second vertical groove 13. The sliders 14 are fixedly installed at the lower ends of both sides of the cabinet 1, and support columns 11 are fixedly installed at the four corners of the top of the cabinet 1. A rain shelter 12 is fixedly installed between the tops of the support columns 11. Support plates 18 are fixedly installed on both sides of the top of the cabinet 1. The sliding connection between the slider 14 and the second vertical groove 13 can increase the stability of the cabinet 1 when rising.

[0032] The working principle of the present invention is as follows: when there is too much water on the ground, the cylinder 501 is turned on to drive the telescopic rod 502 to extend and retract, so that the mounting block 503 on the telescopic rod 502 moves. When the mounting block 503 moves, the connecting plate 505 is driven to move by the first connecting column 504 provided. The connecting plate 505 drives the linkage block 507 to slide in the transverse groove 16 through the second connecting column 506 connected by rotation, so that the third connecting column 508 on the linkage block 507 moves. Since the third connecting column 508 is rotatably connected to the first jacking plate 509, and the first jacking plate 509 is rotatably connected to the center column 510, when the third connecting column 508 moves, the center column 510 is driven to move by the first jacking plate 509. Since the center column 510 is rotatably connected to the second jacking plate 511, the second jacking plate 511 is rotatably connected to the mounting column 513. It is movably connected in the transverse groove 16, so when the center column 510 moves, the second lifting plate 511 and the first lifting plate 509 are driven to move closer. Since a connecting block 512 is installed on the center column 510, the connecting block 512 is slidably connected in the bottom groove 17 at the bottom of the cabinet 1, so when the center column 510 moves, it drives the connecting block 512 to slide in the bottom groove 17, so that the cabinet 1 is lifted. Since sliders 14 are installed at the lower ends of both ends of the cabinet 1, and the sliders 14 are slidably connected in the second vertical groove 13, when the cabinet 1 rises, the sliding connection between the sliders 14 and the second vertical groove 13 can increase the stability of the rise of the cabinet 1. The present invention provides a lifting mechanism 5, which can make the cabinet 1 rise away from the accumulated water when the cabinet 1 is in a waterlogged area, thereby preventing the accumulated water from flowing into the interior of the cabinet 1 and causing damage to the interior of the cabinet 1.

[0033] Embodiment 2:

[0034] like Figure 5 As shown, the rain shield mechanism 9 includes a motor 901, which is fixedly mounted on the top of the cabinet 1, and a rotating shaft 902 is fixedly connected to the output end of the motor 901. A main gear 903 is fixedly mounted on one end of the rotating shaft 902 close to the motor 901, and a driven gear 904 is meshedly connected to one side of the main gear 903. A connecting shaft 905 is fixedly mounted on the driven gear 904. The rotating shaft 902 and the connecting shaft 905 both pass through one of the support plates 18 and are rotatably connected to the side wall of the other support plate 18. The rotating shaft 902 and the connecting shaft 905 are both fixedly installed with a linkage plate 906, and a through groove 907 is provided on the linkage plate 906. A cylinder 908 is slidably connected in the through groove 907. A mounting plate 909 is fixedly installed on the cylinder 908. A baffle 910 is fixedly installed at the bottom of the mounting plate 909. A through hole 911 is provided at the center of the baffle 910. Slide plates 912 are fixedly installed on both sides of the baffle 910 close to one end of the cabinet 1. The slide plates 912 are slidably connected in the first vertical groove 7.

[0035] Working principle: When it rains, the motor 901 is turned on by operation to drive the shaft 902 to rotate, so that the main gear 903 on the shaft 902 rotates, and the main gear 903 drives the connecting shaft 905 to rotate at the same time by meshing with the driven gear 904, so that the linkage plate 906 on the shaft 902 and the connecting shaft 905 rotates. Since the linkage plate 906 is provided with a through groove 907, and the through groove 907 is slidably connected with a cylinder 908, when the linkage plate 906 rotates, it drives the cylinder 908 to slide in the through groove 907. A mounting plate 909 is installed on the column 908, and a baffle 910 is installed at the bottom of the mounting plate 909. Slide plates 912 are installed on both sides of the baffle 910 close to one end of the cabinet 1. The slide plates 912 are slidably connected in the first vertical groove 7. Therefore, when the cylinder 908 slides in the through groove 907, the baffle 910 is driven to move through the mounting plate 909. The baffle 910 is slidably connected to the first vertical groove 7 through the slide plate 912 and slides on the side wall of the cabinet 1, thereby blocking the heat dissipation holes 6 opened on both sides of the cabinet 1 to prevent rainwater from entering the cabinet 1 through the heat dissipation holes 6.

[0036] Embodiment 3:

[0037] like Figure 6 As shown, the cleaning mechanism 10 includes a pull block 1001, on which a slide rod 1002 is fixedly mounted. The slide rod 1002 passes through the baffle 910 through the through hole 911 and is slidably connected in the through hole 911. A movable plate 1003 is fixedly mounted on one end of the slide rod 1002 away from the pull block 1001, and a plurality of brushes 1004 are fixedly mounted on one end of the movable plate 1003 close to the cabinet 1.

[0038] Working principle: When the heat dissipation hole 6 is too dirty, the baffle 910 is moved to the heat dissipation hole 6 through the rain shield mechanism 9, and then the pull block 1001 is pulled to make the slide bar 1002 on the pull block 1001 slide back and forth in the through hole 911 at the center of the baffle 910. Since a moving plate 1003 is installed on the slide bar 1002, and a plurality of brushes 1004 are installed on the moving plate 1003, when the slide bar 1002 slides back and forth, it drives the moving plate 1003 to reciprocate, so that the brush 1004 on the moving plate 1003 cleans the heat dissipation hole 6.

[0039] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution of the present invention and its improved concept within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention. In addition, the word "including" does not exclude other elements or steps, and the word "one" before an element does not exclude the inclusion of "multiple" elements. The multiple elements stated in the product claim can also be implemented by one element through software or hardware. The words first, second, etc. are used to indicate names, and do not indicate any specific order.
