The fine-pored sponge 50 is composed of Due to the high pore density, it can absorb water better, and it is easy to squeeze out the absorbed water. The fine-pored sponge 50 is placed on the tray 60, and the fine-pored sponge 50 is used to absorb moisture in the cabinet 10; the squeezing device 20 is arranged at the top of the "U"-shaped seat 11, and the two side plates of the "U"-shaped seat 11 are fixed, so that the squeezing device 20 always moves vertically inside the "U"-shaped seat 11, and the squeezing device 20 and the fine-pored sponge 50 are opposite to each other up and down, and the squeezing device 20 is used to squeeze the fine-pored sponge 50 to squeeze the water in the fine-pored sponge 50 onto the tray 60; the drain pipe 70 is arranged on the tray The tray 60 is close to the cabinet 10, one end of the drain pipe 70 is connected to the tray 60, and the other end of the drain pipe 70 passes through the cabinet 10 and extends to the outside of the cabinet 10. The drain pipe 70 is used to drain the accumulated water on the tray 60; the first controller 90 is connected to the mass sensor 80 and the squeezing device 20; wherein the mass sensor 80 is used to monitor the weight of the tray 60 and the fine-pored sponge 50, and the first controller 90 is used to control the squeezing device 20 to squeeze the fine-pored sponge 50 according to the monitoring signal of the mass sensor 80; when the water absorbed by the fine-pored sponge 50 reaches a certain weight, the mass sensor 80 is used to control the squeezing device 20 to squeeze the fine-pored sponge 50. The sensor 80 transmits the signal that the tray 60 and the fine-porous sponge 50 have reached the preset weight to the first controller 90, and the first controller 90 transmits the motion signal to the squeezing device 20, and the squeezing device 20 starts to work. After being squeezed by the squeezing device 20, the water in the fine-porous sponge 50 flows to the tray 60, and the accumulated water is discharged from the drain pipe 70 connected to the tray 60 to the outside of the cabinet 10; the problem of condensation due to humidity in the low-yield well intelligent split control cabinet in the prior art is solved, which causes the equipment and devices in the cabinet to short-circuit or corrode, thereby causing the operation failure of the RTU control cabinet.

[0028] A mesh partition is placed one centimeter above the bottom of the tray 60 so that the accumulated water flowing down from the fine-porous sponge 50 squeezed by the squeezing device 20 will not be absorbed by the fine-porous sponge 50 for a second time.

[0029] When implementing it, Figure 4As shown, the squeezing device 20 includes a motor 21, a rotating disk 22, a connecting rod 23 and a squeezing plate 24.

The air circulation device 30 solves the problem that the drying effect in the cabinet is not obvious due to the fine-porous sponge 50 absorbing moisture too slowly, and greatly improves the dehumidification efficiency.

[0031] Furthermore, if Figure 5 As shown, the air circulation device 30 includes: a fan 31, a humidity sensor 33, and a second controller 32. The fan 31 is fixedly installed on the inner wall of the other side of the cabinet 10; the humidity sensor 33 is arranged at the top of the fan 31, and the humidity sensor 33 is used to monitor the humidity in the cabinet 10; the second controller 32 is connected to both the fan 31 and the humidity sensor 33, and the second controller 32 is used to control the operation of the fan 31 according to the humidity information monitored by the humidity sensor 33; when the humidity sensor 33 detects that the humidity in the cabinet 10 reaches a preset value, the humidity sensor 33 transmits a signal that the humidity has reached the preset value to the second controller 32, and the second controller 32 then transmits the driving signal to the fan 31, and the fan 31 starts to operate; the air circulation device 30 not only improves the dehumidification efficiency, but also has a simple structure and low cost.

[0032] Furthermore, the control cabinet also includes: a ventilation device 40, which is arranged below both sides of the cabinet 10, and is used to circulate air between the inside and outside of the cabinet 10 to reduce condensation caused by excessive temperature difference between the inside and outside of the cabinet 10.

[0033] Furthermore, the ventilation device 40 includes ventilation windows 41 and baffles 42. There are two ventilation windows 41, which are arranged on both sides of the cabinet 10 and opposite to each other; there are two baffles 42, which are respectively installed at the connection between the two ventilation windows 41 and the cabinet 10 through hinges 43 to open or close the two ventilation windows 41; by setting the ventilation windows 41, when the internal temperature of the cabinet 10 is high, ventilation with the outside can be achieved to reduce the internal temperature; when the temperature difference between the inside of the cabinet 10 and the outside is too large, the baffles 42 are opened to allow the air inside the cabinet 10 to circulate with the outside to avoid the formation of condensation beads; when the temperature difference between the inside of the cabinet 10 and the outside is not large, but the control cabinet is located in a humid environment and there are a lot of dust and impurities in the air, in order to avoid dust and impurities entering the cabinet 10 and causing problems with the circuits in the cabinet 10, the baffles 42 can be closed to make the cabinet 10 in a closed state, and dehumidification can be performed using the internal squeezing device 20.

[0034] During specific use, when the environment in which the cabinet 10 is located is relatively humid, and thus the humidity inside the cabinet 10 is relatively high, the humidity sensor 33 monitors that the humidity of the cabinet 10 reaches a preset humidity and then transmits a signal to the second controller 32. The second controller 32 transmits a driving signal to the fan 31, and the fan 31 starts to blow air toward the fine-porous sponge 50 to accelerate the fine-porous sponge 50 to absorb moisture in the air; after the fine-porous sponge 50 absorbs a certain amount of moisture, its weight begins to increase. When the mass sensor 80 monitors that the tray 60 and the fine-porous sponge 50 reach a preset weight, it transmits a signal to the first controller 90. The first controller 90 transmits a driving signal to the extrusion device 20, and the extrusion device 20 starts to squeeze the fine-porous sponge 50. The moisture in the fine-porous sponge 50 flows from the fine-porous sponge 50 to the mesh partition and then flows into the tray 60, and is finally discharged from the drain pipe 70 connected to the tray 60 to the outside of the cabinet 10; if the temperature difference between the inside of the cabinet 10 and the outside is too large, the two baffles 42 are opened to allow the air inside the cabinet 10 and the outside to circulate through the two ventilation windows 41.

[0035] Example 1

[0036] When the low-yield well intelligent intermittent anti-condensation RTU control cabinet is located in a very humid place, in order to prevent condensation, the two baffles 42 can be opened to allow the air inside the cabinet 10 and the outside to circulate through the two ventilation windows 41.

[0037] Example 2

[0038] When the location of the low-yield well intelligent interval anti-condensation RTU control cabinet is not humid, but there are too many impurities such as dust in the environment, the two baffles 42 can be closed to prevent external dust and other impurities from flying into the cabinet 10, thereby reducing the impact of impurities in the air on the operation of the internal circuits of the cabinet 10; after the two baffles 42 are closed, in order to prevent condensation due to the large temperature difference between the inside and outside of the cabinet 10, the extrusion device 20, the fine-porous sponge 50, the tray 60, the drain pipe 70, the quality sensor 80, the first controller 90 and the air circulation device 30 can be used to absorb the moisture inside the cabinet 10 and discharge the water out of the cabinet 10.
