Description

Technical Field

[0001] The present application relates to the technical field of electric control cabinets, and in particular to an electric control cabinet. Background Art

[0002] The electric control cabinet is a central integrated device for controlling electrical appliances, which usually contains a large number of electrical components. If the humidity inside the electric control cabinet is too high, it will easily accelerate the corrosion of components, leading to problems such as poor insulation, poor contact and leakage, which will not only reduce the service life of the electrical components, but also create major safety hazards.

[0003] At present, common solutions to the moisture-proof problem of electric control cabinets mainly include: installing heaters to use heat energy to dissipate internal moisture and improve the overall temperature and humidity level; adding vents to introduce dry air from the outside through natural or forced ventilation to reduce internal humidity; using chemical desiccant to absorb excess moisture inside the electric control cabinet. Although these methods can alleviate the moisture problem to a certain extent, they have their own limitations and shortcomings in practical applications.

[0004] For example, although heaters can remove some moisture, they will increase the temperature inside the electric control cabinet and increase the risk of fire; although vents can introduce air, when the humidity of the outside air is high, the dehumidification effect is not ideal, and the introduced outside air may also bring in dust, affecting the operation of the equipment; and chemical desiccant has limited effect and needs to be replaced regularly. Therefore, how to effectively solve the problem of excessive moisture inside the electric control cabinet has become a technical problem that needs to be solved urgently. Summary of the invention

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-6 This application is described in further detail.

[0030] Embodiment 1: The present application embodiment discloses an electric control cabinet. Figure 1 and Figure 2, including a cabinet 1, a first partition 11 is arranged above the cabinet 1, and the first partition 11 divides the interior of the cabinet 1 into two spaces, an upper space and an lower space, wherein the first partition 11 and the top of the cabinet 1 form a dehumidification chamber 2, and the space between the first partition 11 and the bottom plate of the cabinet 1 is the main space for installing various electrical components. The first partition 11 is a metal plate, and a first air inlet 111 and a first air outlet 112 are respectively opened at both ends of the first partition 11, and dustproof nets can be arranged on the first air inlet 111 and the first air outlet 112.

[0031] Reference Figure 2 and Figure 3 In the embodiment of the present application, a dehumidification device 3 is provided in the dehumidification chamber 2, and the dehumidification device 3 mainly includes a compressor 31, an evaporator 32 and a condenser 33, and an exhaust fan 34 for drawing the air in the cabinet from the first air inlet 111 into the dehumidification chamber 2. Specifically, a partition plate can also be provided in the dehumidification chamber 2, and the dehumidification chamber 2 is divided into a smaller first space and a larger second space by the partition plate. The compressor 31 is provided in the first space, the first air inlet 111 and the first air outlet 112 are both connected to the second space, and the evaporator 32 is provided on a side close to the first air inlet 111, the exhaust fan 34 is provided on a side close to the first air outlet 112, and the condenser 33 is provided between the evaporator 32 and the exhaust fan 34.

[0032] The exhaust port of the compressor 31 is connected to the inlet of the condenser 33, and the outlet of the condenser 33 is connected to the inlet of the evaporator 32 through a throttling element. The throttling element can be a capillary tube or an expansion valve. The outlet of the evaporator 32 is connected to the air intake port of the compressor 31. When working, the exhaust fan 34 is started so that the air in the cabinet 1 is sucked in from the first air inlet 111. After the air flow passes through the evaporator 32, the condenser 33 and the exhaust fan 34 in sequence, it is sent back to the inside of the cabinet 1 through the first air outlet 112. At the same time, the compressor 31 compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas. The high-temperature and high-pressure gas enters the condenser 33 and becomes a low-temperature and high-pressure liquid through heat exchange with the outside air or cooling water; the low-temperature and high-pressure liquid is throttled and reduced in pressure by the throttling element and becomes a low-temperature and low-pressure gas; the low-temperature and low-pressure gas enters the evaporator 32, absorbs the heat in the air, and condenses the water vapor in the air flow passing through the evaporator 32 into water droplets attached to the evaporator 32, thereby achieving dehumidification and drying of the air. A water receiving box 4 is provided on the first partition plate 11 below the condenser 33; water droplets condensed on the evaporator 32 can drip into the water receiving box 4 for collection. The detailed working principle of the dehumidification device 3 is prior art and will not be described in detail here.

[0033] Preferably, a humidity sensor 17 may be provided in the cabinet 1, and the humidity sensor 17 is connected to the dehumidification device 3, so that when the humidity in the cabinet 1 reaches a preset value, the dehumidification device 3 can be automatically started to dehumidify the air in the cabinet.

[0034] Reference Figure 1 and Figure 4 In the embodiment of the present application, Figure 1 The positions shown are for reference only. A second air inlet 12 is provided on the left side wall of the cabinet 1, a second air outlet 13 is provided on the right side wall, and a second partition 14 is also provided on the inner side wall on the left side of the cabinet 1. A relatively closed air inlet chamber 5 is formed between the second partition 14 and the side wall of the cabinet 1. A filter ring 6 is provided between the side wall of the cabinet 1 and the second partition 14. The axis of the filter ring 6 is provided perpendicular to the side wall of the cabinet 1, and the second air inlet 12 is connected to the inner space of the filter ring 6. The filter ring 6 is used to filter impurities and dust in the air, and its side wall can preferably be composed of multiple layers of fine filter mesh. A third air inlet 141 is provided on the second partition 14, and the third air inlet 141 is connected to the outer space of the filter ring 6.

[0035] It should be noted that the first air inlet 111 is preferably arranged on the same side as the third air inlet 141. When the dehumidification device 3 inside the cabinet 1 is working, the exhaust fan 34 draws the air inside the cabinet 1 into the dehumidification chamber 2, and sends the dried air back into the cabinet 1. At this time, the flow of air can drive the air outside the cabinet 1 into the cabinet 1, and cooperate to dehumidify or cool the inside of the cabinet 1. At the same time, preferably, an air duct check valve can also be set at the second air outlet 13 to limit the wind outside the cabinet 1 from entering the cabinet 1 from the second air outlet 13. In other embodiments, fans can also be set at the second air inlet 12 and the second air outlet 13, so that when the temperature inside the cabinet is high, starting the fan can draw the outside air into the cabinet 1 for circulation, and cool the inside of the cabinet 1.

[0036] After passing through the second air inlet 12, the air outside the cabinet 1 enters the inner side of the filter ring 6, then passes through the filter ring 6, reaches the outer side of the filter ring 6, flows along the air inlet cavity 5, and finally enters the cabinet 1 from the third air inlet 141. Optionally, dust screens can be set at the first air inlet 111, the first air outlet 112, the second air inlet 12, the third air inlet 141, and the second air outlet 13.

[0037] Reference Figure 2 and Figure 4In the embodiment of the present application, a water storage box 15 is fixed on the side wall of the cabinet 1, and the water storage box 15 is connected to the water receiving box 4 through a water pipe, so that the water stored in the water receiving box 4 can be sent to the water storage box 15 for storage. The lower end of the water storage box 15 can be set to a constricted shape, and a water outlet pipe 151 is set at the constricted position. A water valve 152 for controlling the water outlet is set on the water outlet pipe 151. The pipe mouth of the water outlet pipe 151 is located above the filter ring 6. When the water valve 152 is opened, the water in the water storage box 15 can be discharged to rinse and clean the filter ring 6 to maintain the dust removal effect of the filter ring 6. A drain pipe 16 is also set on the side wall of the lower end of the cabinet 1. One end of the drain pipe 16 is connected to the air inlet chamber 5, and the other end extends out of the cabinet 1, which is used to discharge the flushed water out of the cabinet 1 in time. A one-way valve and other structures can be set in the drain pipe 16 to limit the water outside the cabinet 1 from flowing back into the cabinet 1.

[0038] Preferably, a water level sensor 153 can be provided in the water storage box 15, and the water valve 152 can be an electric valve. The water level sensor 153 is connected to the water valve 152 through a signal. When the water level in the water storage box 15 rises to a certain level, the water valve 152 can be automatically controlled to open to flush the filter ring 6.

[0039] The implementation principle of an electric control cabinet in the embodiment of the present application is as follows: when the humidity sensor 17 detects that the humidity inside the cabinet 1 reaches a preset value, the dehumidification device 3 is automatically started, and the dehumidification device 3 continuously draws the air inside the cabinet 1 into the dehumidification chamber 2, dehumidifies and dries the air, and then sends it back to the cabinet 1. The condensed water during the operation of the dehumidification device 3 is collected by the water receiving box 4 and sent to the water storage box 15 for storage. When the water level sensor 153 in the water storage box 15 detects that the water level reaches a preset position, the water valve 152 is automatically opened to discharge water flow to flush the filter ring 6 and clean the filter ring 6; the cleaned water flow is discharged from the cabinet 1 through the drain pipe 16.

[0040] By arranging a dehumidifier 3 in the electrical control cabinet, the air in the cabinet can be dried, thereby achieving effective control of the humidity in the cabinet; at the same time, a second air inlet 12 and a filter ring 6 are arranged to introduce air from the outside of the cabinet 1 into the cabinet 1, dehumidify and cool the inside of the cabinet 1, and filter the air at the same time, without bringing in impurities and dust to affect the electronic components inside the cabinet 1; and a water storage box 15 is arranged to store the condensed water generated by the dehumidifier 3 in time, thereby avoiding the accumulation of condensed water in the cabinet 1 and keeping the cabinet dry; the condensed water stored in the water storage box 15 can also be used to rinse and clean the filter ring 6, which helps to maintain the cleaning effect of the filter ring 6 and improve the stability of the use of the electrical control cabinet.

[0041] Embodiment 2: The difference between the embodiment of the present application and the embodiment 1 is that the filter ring 6 is fixed by a rotation connection. Figure 4and Figure 5 Specifically, one end of the positioning ring 61 is rotatably connected to the positioning ring 61 by means of a bearing or the like, and the positioning ring 61 is fixed to the side wall of the cabinet 1 by means of bolts or buckles or the like. A positioning groove is provided on the side of the second partition plate 14 facing the air inlet chamber 5, and the other end of the positioning ring 61 is rotatably inserted into the positioning groove. At the same time, in this embodiment, the center position of the water outlet pipe 151 below the water storage box 15 is staggered relative to the axis position of the filter ring 6 in the horizontal projection, that is, the mouth of the water outlet pipe 151 faces the side position of the filter ring 6. When the water in the water storage box 15 falls along the water outlet pipe 151, the impact force of the water flow can drive the filter ring 6 to rotate, thereby circumferentially flushing the filter ring 6. Compared with fixed-point flushing, the cleaning effect of the filter ring 6 can be improved.

[0042] Reference Figure 5 and Figure 6 Furthermore, in this embodiment, a central column 7 is fixed to the second partition plate 14, and the central column 7 extends inside the filter ring 6, and can be preferably coaxially arranged. Cleaning bristles 71 are fixed to the side wall above the central axis, and the cleaning bristles 71 are evenly arranged along the length direction of the central column 7, and the ends of the cleaning bristles 71 abut against the inner side of the filter ring 6; when the filter ring 6 rotates under the force of the water flow, the cleaning bristles 71 can continuously brush the inner side wall of the filter ring 6, thereby further improving the cleaning effect of the filter ring 6.

[0043] Furthermore, an impact ball 72 is provided on the side wall below the center column 7, and the impact ball 72 is connected to the center column 7 by a connecting rope. In a natural state, there is a gap between the center ball and the inner wall of the filter ring 6. A plurality of convex strips 62 are provided circumferentially on the inner wall of the filter ring 6. When the filter ring 6 rotates and drives the convex strips 62 to rotate to the lower position, the impact ball 72 hits the convex strips 62, so that the filter ring 6 vibrates intermittently, which helps to shake off the impurities on the filter ring 6 on the one hand, and on the other hand, when the flushing is finished, the filter ring 6 can still keep rotating for a certain period of time. At this time, the vibration of the filter ring 6 driven by the impact ball 72 can help to shake off the water droplets remaining on the filter ring 6.

[0044] Embodiment 3: The difference between the present application and the embodiment 1 and the embodiment 2 is that the air inlet cavity 5 is further provided with a ventilation duct 52 and a water duct 51 to guide the air. Figure 4 and Figure 5Specifically, a water pipe 51 and a ventilation pipe 52 are formed between the side wall of the cabinet 1 and the second partition 14 by setting a partition, wherein the water pipe 51 preferably extends in the vertical direction, and the ventilation pipe 52 preferably extends in the horizontal direction, and the filter ring 6 is arranged at the connection between the water pipe 51 and the ventilation pipe 52. The water outlet pipe 151 of the water storage box 15 is connected to the upper end of the water pipe 51, and the drain pipe 16 is connected to the lower end of the water pipe 51; the third air inlet 141 is connected to the ventilation pipe 52, and is preferably arranged at both ends of the ventilation pipe 52.

[0045] Reference Figure 4 and Figure 5 , further, the second partition 14 is also provided with an opening and closing assembly 8 for closing the water pipe 51 or the ventilation pipe 52. Among them, the opening and closing assembly 8 includes two first baffles 81 relatively rotated and arranged on both sides of the water pipe 51. With the filter ring 6 as a reference, the two first baffles 81 are arranged at the upper end of the filter ring 6. When the two first baffles 81 rotate to a horizontal state in a direction close to each other, the ends of the two first baffles 81 abut against each other, thereby closing the water pipe 51 at the upper end of the filter ring 6. The opening and closing assembly 8 also includes two second baffles 82 relatively rotated and arranged on both sides of the water pipe 51. Correspondingly, the two second baffles 82 are arranged at the lower end of the filter ring 6 to close the water pipe 51 at the lower end of the filter ring 6. When the two first baffles 81 rotate downward and the two second baffles 82 rotate upward, the first baffles 81 and the second baffles 82 relatively arranged can abut against each other, thereby opening the two water pipes 51 on the upper and lower sides of the filter ring 6, and closing the ventilation pipes 52 on the left and right sides of the filter ring 6 at the same time.

[0046] The opening and closing assembly 8 also includes a power source 83 for driving the first baffle 81 and the second baffle 82 to rotate. The power source 83 can be a motor, which is fixed on the second baffle 14. Correspondingly, the first baffle 81 and the second baffle 82 are both connected with a rotating shaft 811, and the two ends of the rotating shaft 811 are respectively rotatably connected to the side wall of the cabinet 1 and the side wall of the second plate; at the same time, the rotating shaft 811 passes through the second baffle 14 and is connected to the output shaft of the motor. The motor is respectively set correspondingly to the first baffle 81 and the second baffle 82, and the motor is preferably connected to the water level sensor 153 signal.

[0047] Further optionally, magnets (not shown in the figure) can be embedded in the ends of the first baffle 81 and the second baffle 82, and the magnets at the ends of the two first baffles 81 and the magnets at the ends of the two second baffles 82 can be attracted to each other, thereby increasing the stability of the connection between adjacent plates. At the same time, when the first baffle 81 and the second baffle 82 are flipped, the magnets built into the ends of the first baffle 81 and the second baffle 82 on the same side can also be attracted to each other.

[0048] In the natural state, the first baffle 81 and the second baffle 82 are both in a horizontal state. At this time, the ventilation duct 52 is opened, and the wind entering from the outside of the cabinet 1 moves along the ventilation duct 52 and enters the cabinet 1 from the third air inlet 141; when the water level sensor 153 senses that the water level has reached the preset value, the motor is started first to drive the first baffle 81 and the second baffle 82 to rotate, thereby closing the ventilation duct 52 and opening the water pipe 51; then the water valve 152 is opened, and the water storage box 15 discharges water to flush the filter ring 6; after a period of flushing, the motor is started again to rotate the first baffle 81 and the second baffle 82, closing the pipes at the same time and opening the ventilation duct 52.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
