DETAILED DESCRIPTION

[0035] The utility model will be further explained in connection with the drawings below.

[0036] The utility model provides a dustproof and heat dissipation PLC control cabinet for hydropower station, as shown in the figure, it includes: Figures 1-3

[0037] Cabinet 1, the side wall of cabinet 1 is provided with louver 4;

[0038] Filtering mechanism 3, filtering mechanism 3 is arranged on the side wall of cabinet 1, and filtering mechanism 3 includes fan 301 fixedly connected on cabinet 1, and fan 301 is provided with adsorbing cotton 307 for adsorbing moisture in air and filter screen 305 for filtering dust in air in sequence at the end away from the inside of cabinet 1.

[0039] It can be understood that fan 301 rotates forward, can make air enter cabinet 1 in sequence after passing through filter screen 305 and adsorbing cotton 307, wherein filter screen 305 can filter the dust in air, and adsorbing cotton 307 can adsorb the moisture and dust in air, to avoid dust and moisture into cabinet 1, and the air in cabinet 1 can take out the heat in cabinet 1 from louver 4, to achieve the effect of dustproof and heat dissipation;In addition, fan 301 reversely rotates, and air can enter cabinet 1 from louver 4 and be discharged through filter screen 305, so that the dust accumulated on filter screen 305 can be cleaned by using flowing air, and then it is beneficial to continuously prevent dust when fan 301 rotates forward.

[0040] In an embodiment, as shown in Figure 1 、 Figure 3 and Figure 4 Filtering mechanism 3 includes fixed seat 302 fixedly connected on the outside of cabinet 1 and connecting seat 304 inserted on the side of fixed seat 302 away from cabinet 1, and the end of connecting seat 304 close to cabinet 1 is fixedly connected with two adsorbing cottons 307, and the two adsorbing cottons 307 are respectively located on the two sides of the end of fan 301 away from the inside of cabinet 1;The two sides of the end of fixed seat 302 away from cabinet 1 are respectively fixedly connected with two filter screens 305, and the two sides of the end of fixed seat 302 close to cabinet 1 are respectively fixedly connected with two inclined plates 306, and the two inclined plates 306 are respectively located on the side away from each other of the two adsorbing cottons 307. ​

[0041] It can be understood that, in this way, when air enters from the end where the fan 301 is arranged, it needs to flow through the filter screen 305, the inclined plate 306 and the adsorbing cotton 307 in sequence, that is, it is ensured that the filter screen 305 can filter dust in the air, and it is ensured that the inclined plate 306 and the adsorbing cotton 307 can cooperate to complete the adsorption treatment of moisture in the air; in addition, when the adsorbing cotton 307 is used for a long time, moisture and dust will accumulate in the adsorbing cotton 307, and by taking out the connecting seat 304, the moisture and dust on the adsorbing cotton 307 can be conveniently disposed of.

[0042] In one embodiment, both adsorbing cottons 307 are bonded to the connecting seat 304.

[0043] In one embodiment, the connecting seat 304 is in sliding connection with the fixing seat 302, and a handle 303 is fixedly connected to the outer side of the connecting seat 304, so as to facilitate the connecting seat 304 to be installed into or taken out of the fixing seat 302.

[0044] In one embodiment, the dustproof and heat dissipation PLC control cabinet for a hydropower station comprises a cleaning mechanism 5, and the cleaning mechanism 5 comprises an intercepting net 504 fixedly connected to the cabinet body 1 and located on the inner side of the louver 4.

[0045] It can be understood that, when the fan 301 rotates reversely, the intercepting net 504 can intercept dust in the air to avoid the dust entering the cabinet body 1.

[0046] In one embodiment, as shown in Figure 3 the cleaning mechanism 5 comprises an electric telescopic rod 502 and a collecting groove 501 fixedly connected to the cabinet body 1, the telescopic direction of the electric telescopic rod 502 is the same as the length direction of the intercepting net 504, the output end of the electric telescopic rod 502 is fixedly connected perpendicularly with a brush 503 abutting against the intercepting net 504, the length direction of the brush 503 is the same as the width direction of the intercepting net 504, and the collecting groove 501 is located directly below the intercepting net 504.

[0047] It can be understood that the electric telescopic rod 502 can drive the brush 503 to brush off dust on the intercepting net 504, and the brushed-off dust can fall into the collecting groove 501 to avoid the dust accumulating on the intercepting net 504.

[0048] In one embodiment, the collecting groove 501 is clamped on the cabinet body 1, so that the collecting groove 501 can be disassembled from the cabinet body 1, thereby facilitating the cleaning of the collecting groove 501.

[0049] In one embodiment, the sidewall of the cabinet body 1 is provided with the cabinet door 2.

[0050] In one embodiment, as shown in Figure 2 the inner wall of the cabinet body 1 is bonded with a separation layer 6.

[0051] In one embodiment, as shown in Figure 2 and Figure 3 The inner wall of the cabinet 1 is fixedly connected with a moisture-proof plate 7.

[0052] As can be seen from the above, the fan 301 rotates forward, which can drive air into the inside of the cabinet 1. Before the air enters the cabinet 1, the air first contacts the filter screen 305, which filters the dust in the air. When there is moisture in the air, the moisture will pass through the filter screen 305 into the fixed seat 302, and through the cooperation of the inclined plate 306 and the adsorbing cotton 307, the moisture in the air can be adsorbed, and the adsorbing cotton 307 can filter the dust, so as to reduce the dust in the air in the cabinet 1, thereby improving the filtering effect of the air entering the cabinet 1.

[0053] When the adsorbing cotton 307 is used for a long time, water and dust will accumulate in the adsorbing cotton 307. By pulling the handle 303, the connecting seat 304 and the adsorbing cotton 307 can be moved out of the inside of the fixed seat 302, so as to clean the adsorbing cotton 307. By reversing the fan 301, air can pass through the intercepting screen 504 into the inside of the cabinet 1, and through the air flow, the dust accumulated on the side wall of the filter screen 305 can be cleaned.

[0054] It is worth noting that when the air in the cabinet 1 flows, the heat in the cabinet 1 will be transferred to the inside of the fixed seat 302. By blowing of the fan 301, the heat acts on the side wall of the filter screen 305, and the dust on the side wall of the filter screen 305 is cleaned, thereby facilitating the subsequent use of the filter screen 305.

[0055] In addition, when the intercepting screen 504 accumulates dust, the electric telescopic rod 502 can be moved downward to drive the brush 503 to clean the side wall of the intercepting screen 504. At the same time, the dust on the side wall of the intercepting screen 504 after cleaning falls into the collecting groove 501, so as to avoid the accumulation of dust in the cabinet 1 or on the outside of the electrical equipment in the cabinet 1.

[0056] It is worth noting that, in order to avoid the incomplete cleaning of the intercepting screen 504 due to the moisture on the surface of the brush 503, the brush 503 is located in the cabinet 1, and when the brush 503 is cleaned, the fan 301 is in a rotating state, so that the dust on the intercepting screen 504 after cleaning is discharged from the inside of the cabinet 1 in time, thereby preventing the accumulation of dust.

[0057] In addition, when the fan 301 reverses, the louver 4 can be used to reduce the moisture of the intercepting screen 504 caused by the contact of water flow to the outside of the intercepting screen 504, and to avoid the damage of the electrical equipment caused by the water flow entering the inside of the cabinet 1.

[0058] In the description of the utility model, it is understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.
