Description

Technical Field

[0002] The switchboard is an important component in electrical engineering, which is used to centrally control and distribute electricity. In commercial buildings, industrial facilities, or residential areas, the switchboard plays a vital role in ensuring that electricity is safely and efficiently transmitted from one source to multiple end-use devices.

[0003] Chinese patent authorization announcement number: CN219394078U discloses a high heat dissipation distribution cabinet. This solution can accelerate the speed of air entering the air intake channel by starting the air intake fan installed at one end of the air intake channel, so that the air flows quickly and enters the air outlet channel through the connecting pipe. It can accelerate the speed of air entering the distribution cabinet, improve the fluidity of the air, improve the heat dissipation efficiency of the distribution cabinet, and avoid overheating inside the distribution cabinet.

[0004] However, in the above scheme, air flow is ensured by opening air inlet holes on the side wall of the distribution cabinet. However, when the distribution cabinet is used in a humid environment, humid gas from the outside will enter the distribution cabinet through the air inlet holes. The humid air contains a high amount of moisture, which can condense on the internal electrical components of the distribution cabinet, causing rust and corrosion of metal parts, thereby shortening the service life of the equipment, increasing maintenance costs and potential safety risks.

[0005] Therefore, it is necessary to provide a movable distribution cabinet for electrical engineering to solve the above problems.

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0034] like Figure 1-4 As shown, the present application provides a movable power distribution cabinet for electrical engineering, including a power distribution cabinet body 1, a cabinet door 2 is hinged on the outside of the power distribution cabinet body 1, and a movable wheel 3 is installed at the bottom of the power distribution cabinet body 1, a heat dissipation window 5 is opened on the outer wall of the power distribution cabinet body 1, a heat dissipation fan 4 is installed on the inner wall of the power distribution cabinet body 1, two air inlet holes 8 are opened at the bottom of the power distribution cabinet body 1, two drying components 7 are arranged at the bottom of the power distribution cabinet body 1, and a driving component 6 is installed at the bottom of the inner wall of the power distribution cabinet body 1;

[0035] Preferably, the number of movable wheels 3 is four, which is convenient for the overall movement of the distribution cabinet. The number and position of the cooling fans 4 and the cooling windows 5 correspond one to one. The number of cooling fans 4 and the cooling windows 5 are both two, which are respectively located on the inner and outer sides of the distribution cabinet body 1, so that the cooling fan 4 can discharge the gas in the distribution cabinet body 1 through the cooling windows 5.

[0036] The drying component 7 includes a turntable 71 and a fixed ring 72. The fixed ring 72 is fixed to the bottom end of the distribution cabinet body 1 through a bracket. The turntable 71 is rotatably connected to the bottom end of the distribution cabinet body 1. Four through holes are opened inside the turntable 71. The inner walls of the four through holes are fixedly connected with a sieve plate 1 74, and the insides of the four through holes are slidably connected with a sieve plate 2 77. A plurality of adsorption balls 76 are arranged inside the four through holes.

[0037] The power distribution cabinet in this solution is used to distribute and control electricity. It is a very critical equipment in electrical engineering. Circuit breakers, terminal blocks, relays and metering devices are installed inside it. Circuit breakers are used to control and protect circuits, terminal blocks are used to connect wires, and relays and metering devices are used to monitor and control power usage.

[0038] In this embodiment, the purpose of heat dissipation is achieved by setting up a heat dissipation fan 4, and external gas is introduced into the distribution cabinet body 1 through the air inlet hole 8, and then discharged through the heat dissipation window 5, ensuring the air circulation inside the distribution cabinet body 1, thereby helping to regulate the temperature and keeping the equipment running within an ideal temperature range.

[0039] Among them, by installing a drying component 7 at the bottom of the distribution cabinet body 1, the drive component 6 is used to control the turntable 71 to rotate intermittently by 90°, so that the four through holes in the turntable 71 correspond to the positions of the air inlet holes 8 in sequence, and by installing adsorption balls 76 in the through holes, the moisture in the gas entering the distribution cabinet body 1 can be adsorbed, which can effectively reduce the moisture entering the distribution cabinet body 1.

[0040] like Figure 4 As shown, four make way grooves 75 are provided on the outer wall of the turntable 71, and the four make way grooves 75 are respectively connected to the four through holes. A connecting rod 79 is fixedly connected to the outer wall of the sieve plate 77, and the connecting rod 79 passes through the make way groove 75. A sliding groove 710 is provided on the inner wall of the fixed ring 72, and a slider 78 matching the sliding groove 710 is installed at the end of the connecting rod 79 away from the sieve plate 77, and the slider 78 is slidably connected to the sliding groove 710.

[0041] In this embodiment, since the adsorption balls 76 will be in a saturated state after absorbing moisture for a long time, that is, the moisture absorption capacity is reduced, a fixed ring 72 is provided on the outer surrounding of the turntable 71. When the turntable 71 rotates intermittently by 90°, the slider 78 can move along the movement trajectory of the slide groove 710. In addition, the slider 78 is restricted by the slide groove 710 and moves in the vertical direction, thereby forcing the sieve plate 2 77 to move vertically in the through hole during rotation, thereby changing the distance between the sieve plate 2 77 and the sieve plate 1 74, squeezing the adsorption balls 76 between the two, removing the adsorbed moisture, and ensuring a good moisture absorption effect. The set yield groove 75 can provide reserved space for the vertical movement of the connecting rod 79.

[0042] It should be noted that, when the turntable 71 is stopped, the sieve plate 2 77 corresponding to the position of the air inlet hole 8 is located at the lowest position, ensuring that the adsorption balls 76 are in an un-squeezed state and a moisture absorbing state.

[0043] like Figure 4 As shown, the adsorption balls 76 are located between the sieve plate 1 74 and the sieve plate 2 77 , and the diameters of the adsorption balls 76 are larger than the sieve hole diameters of the sieve plates 2 77 and 1 74 . The adsorption balls 76 are made of silica gel.

[0044] In this embodiment, the adsorption ball 76 made of silica gel has good hygroscopicity and a porous structure, and can absorb water equivalent to more than 40% of its own weight. After the adsorption ball 76 absorbs moisture, the moisture can be discharged through a squeezing operation, which can not only restore its dry state, but also allow the adsorption ball 76 to be reused.

[0045] like Figure 3As shown, the drive assembly 6 includes a motor 61 fixed to the bottom end of the inner wall of the distribution cabinet body 1, the output end of the motor 61 passes through the distribution cabinet body 1 and is fixedly connected to a driving gear 62, and the outer wall of the turntable 71 is fixedly connected to an outer gear ring 73, which is meshed with the driving gear 62.

[0046] In this embodiment, the driving assembly 6 is used to control the synchronous operation of the two drying assemblies 7. Specifically, the driving gear 62 is controlled to rotate by the set motor 61, and then the turntable 71 is controlled to intermittently rotate 90° under the meshing connection between the driving gear 62 and the outer gear ring 73.

[0047] It should be noted that the click 61 can use a stepper motor, which can decompose a complete rotation into a large number of small steps. By controlling the number and sequence of pulse signals received by the motor, the rotation angle of the motor can be accurately controlled, thereby realizing intermittent 90° rotation of the turntable 71.

[0048] like Figure 4 As shown, the slide groove 710 is arranged on the inner wall of the fixing ring 72 in an annular wave shape.

[0049] In this embodiment, by arranging the slide groove 710 in a circular wave shape, when the turntable 71 rotates, the slider 78 moves along the wave-shaped trajectory, which can force the sieve plate 77 to move vertically in the through hole during the rotation, thereby achieving the purpose of squeezing the adsorption ball 76. The adsorption ball 76 can continuously maintain its moisture absorption performance, thereby continuously protecting the electrical components in the distribution cabinet from the adverse effects of moisture.

[0050] Working principle:

[0051] The motor 61 is provided to control the driving gear 62 to rotate, and the meshing connection between the driving gear 62 and the outer gear ring 73 is used to control the turntable 71 to rotate intermittently by 90°, so that the four through holes in the turntable 71 correspond to the positions of the air inlet holes 8 in sequence. By installing adsorption balls 76 in the through holes, the moisture in the gas entering the distribution cabinet body 1 can be adsorbed, which can effectively reduce the moisture entering the distribution cabinet body 1. In addition, when the turntable 71 rotates, the slider 78 can move along the movement trajectory of the slide groove 710. In addition, the slider 78 is restricted by the slide groove 710 and moves in the vertical direction, thereby forcing the sieve plate 2 77 to move vertically in the through hole during its rotation, thereby changing the distance between the sieve plate 2 77 and the sieve plate 1 74, squeezing the adsorption balls 76 located between the two to remove the adsorbed moisture, so as to ensure a good moisture absorption effect.

[0052] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
