Its core part adopts load switches and fuses. It has the advantages of simple structure, small size, low price, and can improve power supply parameters and performance as well as power supply safety. Ring network refers to a ring distribution network, that is, the power supply trunk line forms a closed ring, and the power supply source supplies power to this ring trunk line, and then distributes power to the outside through high-voltage switches from the trunk line. Ring network boxes are widely used in distribution stations and box-type substations in load centers such as urban residential areas, high-rise buildings, large public buildings, factories and enterprises.

[0003] Since the current operating environment of the distribution ring network box is generally harsh and affected by environmental factors such as weather, the humidity inside the box is high and condensation is serious, it can no longer meet the needs of reliable operation of the distribution automation system, and the workload of operation and maintenance is huge. Therefore, a micro-positive pressure fresh air fan is needed.

[0004] The existing micro-positive pressure fresh air fan on the side of the ring network box does not have the air conditioning function, so that the airflow with high humidity from the outside cannot be dehumidified when entering the ring network box, resulting in high humidity and condensation in the box, thus affecting the reliability and safety of the ring network box operation.

When the ring network box needs to be ventilated, the fan is started, and the external airflow is transported into the dehumidification chamber through the air intake pipe and the air supply pipe. The moisture in the airflow is absorbed by the breathable absorbent cotton in the dehumidification chamber to achieve dehumidification of the airflow. At the same time, the dehumidified airflow enters the cooling chamber, and the airflow can be cooled by the refrigeration plate, so as to achieve cooling regulation of the airflow, which is beneficial for the air outlet to transport the cooling airflow into the ring network box, so as to achieve heat dissipation and cooling in the ring network box, and avoid condensation in the ring network box.

[0007] As a preferred technical solution, a temperature sensor is installed in the air intake pipe, and the temperature sensor is electrically connected to the refrigeration plate, so that the temperature sensor can detect the temperature of the external air flow and adjust and control the refrigeration plate to perform corresponding cooling.

[0008] As a preferred technical solution, the cabinet is provided with a primary gas utilization component and a secondary gas utilization component, and the fast-flowing airflow in the gas pipe provides operating driving force for the primary gas utilization component and the secondary gas utilization component.

[0009] As a preferred technical solution, the gas transmission first-stage utilization assembly includes a first cylinder, a first piston, a negative pressure pipe, an electric-controlled one-way valve, a first transmission rod, a first sliding hole, a runner, a connecting shaft and a traction rod;

[0010] Two first cylinder bodies are symmetrically installed on both sides of the cabinet, and first pistons are slidably installed in the two first cylinders. The upper part of the first cylinder body is connected to the air supply pipe through a negative pressure pipe, and an electrically controlled one-way valve is arranged on the negative pressure pipe.

[0012] As an optimal technical solution, an electrically controlled intake valve is installed on the upper part of the first cylinder body, and a position sensor is installed on the connecting shaft. The position sensor is electrically connected to the electrically controlled one-way valve and the electrically controlled intake valve. When the position sensor is at the lowest point, the electrically controlled one-way valve is controlled to be opened and the electrically controlled intake valve is closed. When the position sensor is at the highest point, the electrically controlled one-way valve is controlled to be closed and the electrically controlled intake valve is opened. In the initial state, the electrically controlled one-way valve is in an open state and the electrically controlled intake valve is in a closed state. When the position sensor moves to the highest point, by controlling the electrically controlled one-way valve to be closed and the electrically controlled intake valve to be opened, the first piston can move upward under the action of gravity, thereby driving the wheel to continue to rotate for half a cycle, so that the wheel can rotate for one cycle under one reciprocating movement cycle of the first piston.

When the rotating wheel rotates, the rotating wheel can drive the reciprocating screw to rotate synchronously through the rotating shaft, so that the slider can move back and forth laterally along the reciprocating screw, and when the sliders on the two groups of reciprocating screws move toward each other, the slider can drive the extrusion plate to compress the breathable water-absorbent cotton through the push-pull rod, so that the moisture absorbed by the breathable water-absorbent cotton can be squeezed out, and when the sliders on the two groups of reciprocating screws move away from each other, the extrusion plate can move upward to drive the breathable water-absorbent cotton to stretch and recover, thereby ensuring the continuous use of the breathable water-absorbent cotton.

Driven wheels are installed at both ends of the rotating rod, and a transmission chain is sleeved on the driven wheel and the rotating wheel. A cam is installed on the rotating rod. A second cylinder body is fixedly installed on the side of the cabinet near the air inlet, and a second piston is slidably installed in the second cylinder body.

The cam can squeeze the force plate during the rotation process. Under the squeezing action, the force plate drives the second piston to move downward in the second cylinder body through the second transmission rod, so that the water sucked in the second cylinder body can be discharged through the drain pipe. When the force plate moves upward under the elastic force of the supporting spring, the second piston can move upward in the second cylinder body, and then the second cylinder body can absorb the water in the dehumidification chamber through the water suction pipe.

[0016] As a preferred technical solution, a groove is provided on the upper surface of the force-bearing plate, a ball is rollingly embedded in the groove, the ball is in point contact with the outer contour of the cam, and the water suction pipe and the drainage pipe are both one-way pipes.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] When the ring network box needs to be ventilated, start the fan, and transport the external airflow to the dehumidification room through the air intake pipe and the air delivery pipe. The moisture in the airflow is absorbed by the breathable water-absorbent cotton in the dehumidification room to achieve dehumidification of the airflow.

[0019] The longitudinal reciprocating movement of the second piston can drive the rotating wheel to rotate, thereby realizing the lateral reciprocating movement of the slider. When the two groups of sliders move toward each other, the slider can drive the extrusion plate to compress the breathable absorbent cotton through the push-pull rod, so that the moisture absorbed by the breathable absorbent cotton can be squeezed out.

[0020] By rotating the cam, the force plate can drive the second piston to move downward in the second cylinder under the extrusion effect, so that the water sucked in the second cylinder can be discharged through the drain pipe. When the force plate moves upward under the elastic force of the supporting spring, the second piston can move upward in the second cylinder, and then the second cylinder can absorb the water in the dehumidification chamber through the water suction pipe.

[0042] like Figure 1-Figure 4 and Figure 7-Figure 8 As shown, the gas transmission secondary utilization assembly 18 includes a fixed plate 1801, a rotating rod 1802, a driven wheel 1803, a transmission chain 1804, a cam 1805, a second cylinder 1806, a second piston 1807, a second transmission rod 1808, a second sliding hole 1809, a force plate 1810, a support spring 1811, a water suction pipe 1812 and a drainage pipe 1813;

[0043] Two fixed plates 1801 are symmetrically installed on the upper part of one side of the cabinet 1 close to the air inlet 9, and rotating rods 1802 are rotatably installed on the two fixed plates 1801.

[0044] A groove is provided on the upper surface of the force-bearing plate 1810, in which a ball is rolled and embedded. The ball is in point contact with the outer contour of the cam 1805. The suction pipe 1812 and the discharge pipe 1813 are both one-way pipes, which are beneficial for the force-bearing plate 1810 and the cam 1805 to always keep close contact, while reducing the friction between the cam 1805 and the force-bearing plate 1810 during rotation.

[0045] Working principle of the present invention:

[0046] When the ring network box needs to be ventilated, the fan 11 is started, and the external airflow is transported to the dehumidification chamber 4 through the air intake pipe 12 and the air delivery pipe 14. The moisture in the airflow is absorbed by the breathable water-absorbent cotton 6 in the dehumidification chamber 4 to achieve dehumidification of the airflow. At the same time, the dehumidified airflow enters the cooling chamber 5, and the airflow can be cooled by the refrigeration plate 8, so as to achieve cooling regulation of the airflow, which is beneficial for the air outlet 16 to transport the cooling airflow into the ring network box, so as to achieve heat dissipation and cooling in the ring network box, and avoid condensation in the ring network box.

[0047] When the air flow is rapidly transported in the air supply pipe 14, the air supply pipe 14 can form a negative pressure in the first cylinder 1701 due to the pressure difference through the negative pressure pipe 1703 and the electrically controlled one-way valve 1704, so that the first piston 1702 can move upward in the first cylinder 1701 under the action of the negative pressure. During the upward movement, the first piston 1702 can drive the first transmission rod 1705 to move upward synchronously, and during the movement, the first transmission rod 1705 can drive the rotating wheel 1708 to rotate by half a cycle through the traction rod 1710 and the connecting shaft 1709.

[0048] When the position sensor 1712 moves to the highest point, by controlling the electric-controlled one-way valve 1704 to close and the electric-controlled intake valve 1711 to open, the first piston 1702 can move upward under the action of gravity, thereby driving the rotating wheel 1708 to continue to rotate for half a cycle, so that the rotating wheel 1708 can rotate for one cycle under one reciprocating movement cycle of the first piston 1702. The height change of the position sensor 1712 can realize intelligent control of the electric-controlled one-way valve 1704 and the electric-controlled intake valve 1711, so that the longitudinal reciprocating movement of the first piston 1702 in the first cylinder body 1701 can be realized.

[0049] When the rotating wheel 1708 rotates, the rotating wheel 1708 can drive the reciprocating screw 1707 to rotate synchronously through the rotating shaft, so that the slider 1715 can move back and forth laterally along the reciprocating screw 1707, and when the sliders 1715 on the two groups of reciprocating screws 1707 move toward each other, the slider 1715 can drive the extrusion plate 1714 to compress the breathable absorbent cotton 6 through the push-pull rod 1716, so that the moisture absorbed by the breathable absorbent cotton 6 can be squeezed out, and when the sliders 1715 on the two groups of reciprocating screws 1707 move away from each other, the extrusion plate 1714 can move upward to drive the breathable absorbent cotton 6 to stretch and recover, thereby ensuring the continuous use of the breathable absorbent cotton 6.

[0050] When the rotating wheel 1708 rotates, the rotating wheel 1708 can drive the driven wheel 1803 to rotate through the transmission chain 1804 during the rotation process, and the driven wheel 1803 can drive the cam 1805 to rotate synchronously through the rotating rod 1802. The cam 1805 can squeeze the force plate 1810 during the rotation process. Under the squeezing action, the force plate 1810 drives the second piston 1807 to move downward in the second cylinder body 1806 through the second transmission rod 1808, so that the moisture sucked into the second cylinder body 1806 can be discharged through the drain pipe 1813. When the force plate 1810 moves upward under the elastic force of the supporting spring 1811, the second piston 1807 can move upward in the second cylinder body 1806, and then the second cylinder body 1806 can absorb the moisture in the dehumidification chamber 4 through the water suction pipe 1812.
