Description

Technical Field

[0001] The present application relates to the field of electrical and electromechanical technology, and more specifically, to an electrical room for a port crane with a moisture-proof function. Background Art

[0002] The electrical room is the core control part of the port container tire crane, rail crane and other mechanical equipment. It should not only have a solid shell, but also have fireproof and heat insulation functions. With the continuous development of society, people's electricity consumption is increasing, and the capacity of the electrical room of the port crane is increasing. However, the cooling and moisture-proof effect of the existing electrical room is poor, which makes the internal humidity of the electrical room of the port crane high. When the humidity in the electrical room is high, it will affect the use of the equipment in the electrical room of the port crane, affect the resistance of some components of the electrical room of the port crane, and cause the components of the electrical room of the port crane to burn out, causing great losses. In addition, the equipment will generate heat during long-term operation, resulting in excessive temperature in the electrical room of the port crane, which shortens the service life of the electrical equipment.

[0003] The document with the prior art publication number CN213622963U provides a port crane electrical room with a moisture-proof function. The device uses the port crane electrical room with a moisture-proof function. When the temperature and humidity sensor detects that the temperature or humidity in the room is too high, the computer receiving the information starts the air conditioner and the dehumidifier. The air conditioner draws outdoor air in through the air conditioner outdoor unit for cooling, and then discharges it into the room through the air outlet on the ventilation pipe. The dehumidifier absorbs and filters the moisture in the air, so that the temperature in the room drops and the air humidity decreases, which is beneficial to prolonging the service life of the electromechanical equipment in the room.

[0004] With regard to the above-mentioned related technologies, the inventor believes that the moisture in the room mainly occurs when the relative humidity of the air is above 90%, and the humid air outside flows into the room. When the device is in use, the ventilation window is in a normally open state. In rainy weather or when the humidity outside is high, the air with higher humidity circulates into the room through the ventilation window, increasing the humidity in the room and increasing the workload of the dehumidifier, so that the room is always in a state of high humidity.

[0005] In view of this, we propose a port crane electrical room with moisture-proof function. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] The purpose of the present application is to provide an electrical room for a port crane with a moisture-proof function, which solves the technical problems in the above-mentioned background technology and achieves a technical effect of making the room body in a relatively sealed state when the external humidity is high, reducing the air with high external humidity from entering the room body, reducing the load of the dehumidifier, and facilitating the rapid reduction of the humidity in the room body.

[0008] 2. Technical solution

[0009] The technical solution of the present application provides an electrical room for a port crane with a moisture-proof function, comprising a room body, vents being symmetrically provided on both sides of the room body, a dehumidifier being installed inside the room body, the vents on one side being rotatably connected to an exhaust fan, and the vents on the other side being rotatably connected to a supply fan, the exhaust fan and the supply fan being both transmission-connected to a driving mechanism, and self-hanging shutters being installed in the vents.

[0010] By adopting the above technical scheme, the room body and the dehumidifier are well known in the technical field and will not be described in detail in this case. The dehumidifier is used to dehumidify the room body. Ventilation holes are set on both sides of the room body. The supply fan transports outdoor air into the room body, and the exhaust fan discharges the air in the room body to the outside to accelerate the air circulation in the room so as to perform heat exchange inside the room body. When the supply fan supplies air, when the exhaust fan faces the vent, the two self-hanging shutters are opened at this time. When the humidity outside is high, the exhaust fan and the supply fan are driven to rotate a certain angle by the driving mechanism. At this time, the exhaust fan and the supply fan circulate inside to accelerate the air circulation in the room so that the dehumidifier can quickly dehumidify the room body. At the same time, the self-hanging shutters are self-hanging and closed without wind force, so that the room body is in a relatively closed space, reducing the high-humidity outdoor air from entering the room.

[0011] As an optional solution to the technical solution of the present application document, support plates are symmetrically installed on the inner side of the vents, and the exhaust fan and the supply fan are symmetrically installed with rotating shafts, which are rotatably connected to the two support plates respectively, and the driving mechanism is installed on one side of the support plate.

[0012] By adopting the above technical solution, the rotating shaft passes through the through hole provided in the support plate, and is connected to the rotating shaft through the driving mechanism, so that the exhaust fan and the supply fan can be rotated and adjusted around the rotating shaft as the axis.

[0013] As an optional solution of the technical solution of the present application document, an insect-proof net is installed in the vent.

[0014] By adopting the above technical solution, flying insects from outside can be prevented from entering the room through the insect-proof net.

[0015] As an optional solution of the technical solution of the present application document, the self-hanging shutter includes a frame, a plurality of shutters and an axis rod, the shutters are fixedly connected to the axis rod, the axis rod is rotatably connected to the frame, and the lower end of the shutter is provided with a groove adapted to the upper end.

[0016] By adopting the above technical solution, the frame is fixedly installed in the vent. When the exhaust fan or the supply fan is running, the louvers are flipped upward with the shaft as the axis under the action of wind, so that an air duct is formed between two adjacent louvers to achieve gas circulation. When the louvers are self-hanging, the upper grooves are placed on the lower louvers to improve the sealing of the self-hanging louvers.

[0017] As an optional solution of the technical solution of the present application document, the driving mechanism includes a stepper motor, a worm and a worm wheel; the stepper motor is fixed on a support plate, the output shaft of the stepper motor is coaxially fixed with the worm, the worm is meshed with the worm wheel, and the worm wheel is coaxially fixed on the rotating shaft.

[0018] By adopting the above technical solution, when the stepper motor drives the worm to rotate, the worm wheel drives the rotating shaft to rotate, and finally the exhaust fan or the supply fan is driven to rotate and adjust through the rotating shaft, and the self-locking cooperation between the worm wheel and the worm can prevent the exhaust fan or the supply fan from rotating during operation.

[0030] The present application is further described in detail below in conjunction with the accompanying drawings.

[0031] A port crane electrical room with moisture-proof function comprises a room body 1, vents 101 are symmetrically provided on both sides of the room body 1, a dehumidifier 2 is installed inside the room body 1, the vents 101 on one side are rotatably connected to an exhaust fan 3, and the vents 101 on the other side are rotatably connected to a blower 4, the exhaust fan 3 and the blower 4 are both transmission-connected to a driving mechanism 6, and a self-hanging shutter 5 is installed in the vents 101.

[0032] Reference Figure 1-Figure 3 , the room 1 and the dehumidifier 2 are well known in the technical field and will not be described in detail in this case. The dehumidifier 2 is used to dehumidify the room 1. Ventilation holes 101 are provided on both sides of the room 1. The air supply fan 4 transports outdoor air into the room 1, and the exhaust fan 3 discharges the air in the room 1 to the outside to accelerate the air circulation in the room 1 so as to perform heat exchange inside the room 1. When the air supply fan 4 supplies air, when the exhaust fan 3 faces the vent 101, the two self-hanging shutters 5 are opened at this time. When the humidity outdoors is high, the exhaust fan 3 and the air supply fan 4 are driven by the driving mechanism 6 to rotate a certain angle. At this time, the exhaust fan 3 and the air supply fan 4 circulate internally to accelerate the air circulation in the room 1 so that the dehumidifier 2 can quickly dehumidify the room 1. At the same time, the self-hanging shutters 5 are self-hanging and closed without wind force, so that the room 1 is in a relatively closed space, reducing the outdoor high-humidity air from entering the room 1.

[0033] Support plates 301 are symmetrically installed on the inner side of the vent 101 , and rotating shafts 302 are symmetrically installed on the exhaust fan 3 and the supply fan 4 . The rotating shafts 302 are rotatably connected to the two support plates 301 respectively, and the driving mechanism 6 is installed on one side of the support plate 301 .

[0034] Reference Figure 2 and Figure 4 The rotating shaft 302 passes through the through hole of the supporting plate 301 and is connected to the rotating shaft 302 through the driving mechanism 6, so that the exhaust fan 3 and the air supply fan 4 can be rotated and adjusted around the rotating shaft 302 as the axis.

[0035] An insect-proof net 102 is installed in the vent 101 .

[0036] Reference Figure 4 , through the anti-insect net 102, to prevent the outside flying insects from entering the room body 1.

[0037] The self-hanging shutter 5 includes a frame 501, a plurality of shutters 502 and a shaft 503. The shutters 502 are fixedly connected to the shaft 503. The shaft 503 is rotatably connected to the frame 501. The lower end of the shutter 502 is provided with a groove 5021 adapted to the upper end.

[0038] Reference Figure 2 and Figure 5 as well as Figure 6 The frame 501 is fixedly installed in the vent 101. When the exhaust fan 3 or the supply fan 4 is running, the louver 502 is flipped upward with the shaft 503 as the axis under the action of wind, so that an air duct is formed between two adjacent louvers 502 to achieve gas circulation. When the louver 502 is self-hanging, the upper groove 5021 is placed on the lower louver 502 to improve the sealing of the self-hanging louver 5.

[0039] The driving mechanism 6 includes a stepper motor 601 , a worm 602 and a worm wheel 603 ; the stepper motor 601 is fixed on the support plate 301 , the output shaft of the stepper motor 601 is coaxially fixed with the worm 602 , the worm 602 is meshed with the worm wheel 603 , and the worm wheel 603 is coaxially fixed on the rotating shaft 302 .

[0040] Reference Figure 2 When the stepper motor 601 drives the worm 602 to rotate, the worm wheel 603 drives the rotating shaft 302 to rotate, and finally drives the exhaust fan 3 or the blower 4 to rotate and adjust through the rotating shaft 302, and the self-locking cooperation between the worm wheel 603 and the worm 602 can prevent the exhaust fan 3 or the blower 4 from rotating during operation.

[0041] A temperature and humidity sensor is installed in the electrical room to monitor the temperature and humidity in the room 1 in real time. The temperature and humidity sensor is connected to the display device in the control room, which is convenient for the staff to observe the data monitored by the temperature and humidity sensor, so as to control the stepper motor 601.

[0042] Working principle: when the humidity in the room 1 is within a normal range, the exhaust fan 3 and the supply fan 4 are both facing the vent 101. At this time, under the action of wind, the louver 502 flips upward with the shaft 503 as the axis, so that an air duct is formed between the two adjacent louvers 502 to achieve gas circulation and heat exchange in the room 1. When the air humidity inside and outside the room 1 is high, the stepper motor 601 starts and drives the exhaust fan 3 and the supply fan 4 to rotate a certain angle. At this time, the air outlet direction of the exhaust fan 3 and the supply fan 4 is away from the vent 101, and the louver 502 droops under the action of gravity and closes the vent 101. The exhaust fan 3 and the supply fan 4 circulate internally to accelerate the air circulation in the room 1. The dehumidifier 2 dehumidifies the air in the relatively sealed room 1, so that the air humidity in the room 1 is quickly reduced to a safe value.
