Description

Technical Field

[0001] The invention relates to the technical field of electric power prefabricated cabins, and in particular to an improved electric power prefabricated cabin. Background Art

[0002] The prefabricated power substation is the core carrier for realizing the "standardized design, factory processing, and prefabricated construction" of the new generation of smart substations. One of its key technologies is the use of prefabricated cabins, and condensation has a great impact on the safe and stable operation of electrical equipment in the prefabricated cabins. Therefore, anti-condensation is the focus of the design and production of prefabricated cabin smart substations. Power equipment generates heat during operation, and ventilation can help dissipate this heat and maintain the normal operating temperature of the equipment.

[0003] The mechanism of condensation is that the temperature inside the prefabricated cabin is lower than the dew point temperature or the absolute humidity inside the cabin is high, the unsaturated water vapor in the air becomes saturated vapor, and the air cannot accommodate too much water vapor. At this time, the water vapor will liquefy, condense and precipitate, thus forming condensation.

[0004] The invention patent with publication number CN117712889A discloses an automatically ventilated electric prefabricated cabin, including a chassis, a cabin, a door panel and a side ventilation frame, etc. The cabin is connected to the top of the chassis, the cabin is provided with a door panel, and the cabin is embedded with side ventilation frames on both sides, and also includes a temperature sensor, a controller, an adjustable assembly structure and an adjustable air intake mechanism. During operation, if the temperature is too high, the temperature sensor can detect it, and at the same time, it can send a signal to the controller to control the dual-axis motor and the guide fan to start and promote ventilation, so as to improve the ventilation and cooling effect. When the temperature is too low, it can control the dual-axis motor to reverse and the guide fan to close, so as to automatically adjust the ventilation effect according to the different temperatures.

[0005] Although the above patent has certain beneficial effects, hot air will enter the cabin when the temperature outside the cabin is higher than the temperature inside the cabin, and cold air will enter the cabin when the temperature outside the cabin is lower than the temperature inside the cabin. After the hot air or cold air enters the cabin, it will come into contact with the cold air or hot air in the cabin, causing the water vapor in the air to condense into water droplets and form condensation. Condensation can cause the equipment to become damp, corroded and damaged, affecting the normal operation and service life of the equipment. Condensation will produce liquid water, which will combine with dust on the surface of components inside the electrical equipment to form a conductive channel, destroying the insulation performance of the electrical devices, causing electrical equipment to experience accidents such as creepage, flashover, short circuit and tripping, thereby making the equipment less practical.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0037] Reference Figures 1 to 8An improved electric power prefabricated cabin includes a base 1, a cabin body 11 is arranged on the top of the base 1, a dehumidification module 12 is arranged on the side wall of the cabin body 11, a controller 13 is arranged on the dehumidification module 12, two temperature sensors 14 are arranged on the dehumidification module 12, and the two temperature sensors 14 are respectively located inside and outside the cabin body 11. A semiconductor refrigeration sheet 15 is fixedly installed on the side wall of the dehumidification module 12, and the semiconductor refrigeration sheet 15 is located inside the cabin body 11. The controller 13 is used to receive monitoring data of the temperature sensor 14 and adjust two working modes of the semiconductor refrigeration sheet 15 according to the monitoring data, namely, refrigeration dehumidification and heating dehumidification. When the external environment temperature is low and the temperature and humidity in the cabin are high, it is necessary to reduce the relative humidity by heating to prevent the occurrence of condensation. At this time, the semiconductor refrigeration sheet 15 performs heating work. When the external environment temperature is high and the temperature difference between the inside and outside of the cabin is large, it is necessary to reduce the temperature and humidity in the cabin by refrigeration to prevent the occurrence of condensation. At this time, the semiconductor refrigeration sheet 15 performs refrigeration work, and the moisture in the environment is cooled to below the condensation temperature by semiconductor condensation dehumidification technology to achieve the dehumidification effect.

[0038] The side wall of the cabin 11 is provided with an air inlet door 2 and an air exhaust door 5, which are located on the same side of the cabin 11 as the dehumidification module 12, and the air inlet door 2 and the air exhaust door 5 are symmetrically distributed on the left and right sides of the dehumidification module 12. A vertical air inlet duct 22 is fixedly installed on the inner wall of the air inlet door 2. The air inlet duct 22 is located inside the cabin 11, and the top of the air inlet duct 22 is sealed and the bottom is open. An air inlet port 21 is provided on the outer wall of the air inlet door 2, and the air inlet port 21 is connected to the air inlet duct 22. 1 is provided with a suction fan (not shown in the figure), air enters the top of the air inlet pipe 22 from the air inlet 21, flows from top to bottom and flows out from the bottom opening thereof, a fixing plate 31 and a mounting block 34 are fixedly installed on the inner wall of the air inlet pipe 22, the fixing plate 31 is located above the mounting block 34, an adjustment mechanism is provided between the fixing plate 31 and the mounting block 34, the adjustment mechanism divides the interior of the air inlet pipe 22 into two channels, the adjustment mechanism is used to change the size of the channels, and the adjustment mechanism includes two groups of adjustment components, the two groups of adjustment components are The motor 3 is fixedly mounted on the outer wall of the air inlet duct 22, the driving plate 32 is fixedly connected to the rotating shaft of the motor 3, the top of the driving plate 32 is rotatably connected to the bottom of the fixed plate 31, the driving plate 32 is located above the connecting plate 33, and is slidably connected to the connecting plate 33, the bottom of the connecting plate 33 is connected to the mounting block 34 through a sliding assembly, the sliding assembly includes a first slide plate 35 and a second slide plate 36, the first slide plate 35 is rotatably connected to the bottom of the connecting plate 33, the second slide plate 36 is slidably connected to the top of the mounting block 34, the second slide plate 36 is located below the first slide plate 35, and is slidably connected to the first slide plate 35. When the external ambient temperature is high and the temperature difference between the inside and outside of the cabin is large, the cabin body 11 is cooled and dehumidified. At this time, the air inhaled by the air inlet 21 is hot air, and the air inhaled by the air inlet 21 needs to be cooled. The two motors 3 are started so that the two driving plates 32 drive the two connecting plates 33 to move away from each other to form an "eight" shape (such as Figure 7 As shown in the figure, the area of ​​the two channels in the air inlet pipe 22 gradually decreases from top to bottom, thereby accelerating the air flow rate and causing the air to cool down rapidly in the air inlet pipe 22, thereby improving the refrigeration efficiency of the cabin 11, reducing the operating time and energy consumption of the refrigeration system, lowering the temperature of the inhaled air, and reducing the temperature difference between the inside of the cabin 11 and the external environment, thereby reducing the probability of condensation, which helps to maintain a dry environment inside the cabin 11.

[0039] A fixed block 4 is fixedly installed on the top of the inner wall of the air inlet pipe 22, and two groups of pressurizing components are arranged on the fixed block 4. The two groups of pressurizing components correspond to the two groups of adjustment components respectively. The pressurizing components include a multi-stage hydraulic cylinder 41 fixedly installed on the top of the fixed block 4, and a push block 42 is fixedly connected to the bottom of the multi-stage hydraulic cylinder 41. The push block 42 is located below the fixed block 4 and above the fixed plate 31. The side of the push block 42 close to the center line of the air inlet pipe 22 is slidably connected to an extrusion block 43. The extrusion block 43 and the push block 42 are fixedly connected with a first spring 44. When the external ambient temperature is low, the temperature and humidity in the cabin The air inlet 21 is relatively high, and the air inlet 21 inhales cold air, which needs to be heated up. At this time, a set of adjustment components is started, and the motor 3 drives the driving plate 32 and the connecting plate 33 to move, so that the first slide plate 35 connected to the bottom of the connecting plate 33 contacts the inner wall of the air inlet pipe 22, closing one of the channels, and then the pressurizing component corresponding to the closed channel is started, and the multi-stage hydraulic cylinder 41 is started, so that the push block 42 drives the extrusion block 43 to move downward, and the side of the extrusion block 43 close to the driving plate 32 is set as an inclined surface. When the first slide plate 35 contacts the inner wall of the air inlet pipe 22, the slope of the driving plate 32 and the extrusion block 4 The extrusion block 43 and the driving plate 32 have the same slope. After contacting the driving plate 32, the extrusion block 43 continues to move downward. During the downward movement of the extrusion block 43, the first spring 44 is squeezed. The reaction force of the first spring 44 on the extrusion block 43 makes the extrusion block 43 and the outer wall of the driving plate 32 completely fit together, so that the extrusion block 43, the driving plate 32, the first slide plate 35 and the inner wall of the air inlet pipe 22 form a closed space. The push block 42 continues to move downward to squeeze the air in the closed space, so that the air pressure increases and the air temperature rises. Then the driving motor 3 drives the first slide plate 35 to reset, and the gas with the increased temperature is discharged into the air inlet pipe 22. The air duct 22 simultaneously drives another group of adjustment components and pressurizing components to heat the cold air, so that the two groups of pressurizing components pressurize and heat the air alternately. By heating the cold air, the temperature inside the cabin 11 can be increased, and the evaporation of moisture can be accelerated, thereby improving the heating and dehumidification effect. The inhaled cold air is heated without affecting the air circulation, thereby avoiding additional energy consumption and achieving the purpose of energy saving. By alternately heating the air, long-term operation of a single heating element is avoided, the failure rate of the equipment is reduced, and the reliability of the equipment is improved.

[0040] Reference Figures 9 to 12An exhaust duct 52 is fixedly installed on the inner wall of the exhaust door 5. The exhaust duct 52 is parallel to the air inlet duct 22. The exhaust duct 52 is located inside the cabin 11. The top and bottom of the exhaust duct 52 are sealed. A strip opening is provided on the side of the exhaust duct 52 away from the exhaust door 5. A sealing mechanism for sealing the strip opening is provided inside the exhaust duct 52. The sealing mechanism includes multiple groups of sealing components. The multiple groups of sealing components are evenly distributed vertically. The sealing component includes two sealing plates 53 slidably connected to the exhaust duct 52. The two sealing plates 53 are used to close the strip opening of the exhaust duct 52. Push plates 54 are fixedly connected to the sides of the two sealing plates 53 away from each other, and the push plates 54 slide with the exhaust duct 52. The two push plates 54 are movably connected, and the sides away from each other of the two push plates 54 are respectively fixedly connected to the inner wall of the exhaust pipe 52 with a second spring 56, and the sides away from each other of the two push plates 54 are respectively fixedly installed with a first magnetic block 55. The outer wall of the exhaust cabin door 5 is provided with an exhaust port 51, and the exhaust port 51 is communicated with the exhaust pipe 52. An exhaust fan (not shown in the figure) is arranged inside the exhaust port 51. The air inlet 21 sucks in the air, and the synchronous exhaust port 51 discharges the air. The outer wall of the exhaust pipe 52 is slidably connected with a movable block 6, and the side of the movable block 6 away from the exhaust cabin door 5 is provided with an air suction port 64, and the air suction port 64 corresponds to the strip opening. The inner wall of the exhaust cabin door 5 is fixedly installed with two vertical slide rails 62, and the two slide rails The rails 62 are symmetrically distributed on both sides of the movable block 6. Electric sliders 61 are fixedly installed on both sides of the movable block 6. The two electric sliders 61 are slidably connected to the slide rails 62 on the corresponding sides. The electric slider 61 is started to drive the movable block 6 to slide up and down along the outer wall of the exhaust pipe 52 to change the height of the air inlet 64. Two second magnetic blocks 63 are fixedly installed on the side wall of the movable block 6. The two second magnetic blocks 63 are symmetrically distributed on both sides of the movable block 6 and correspond to the two first magnetic blocks 55 respectively. The first magnetic block 55 and the second magnetic block 63 on the corresponding side have opposite magnetic properties and attract each other. When cooling and dehumidifying, the hot air inside the cabin 11 needs to be discharged. The electric slider 61 is started to drive the movable block 6 along the outer wall of the exhaust pipe 52. The outer wall of the exhaust duct 52 moves upward, so that the air intake port 64 is aligned with the uppermost sealing component, and the second magnetic block 63 attracts the first magnetic block 55 on the corresponding side, so that the two first magnetic blocks 55 drive the two push plates 54 to move away from each other, and the two sealing plates 53 follow the two push plates 54 to move away from each other, so that the air intake port 64 is connected to the exhaust duct 52, and the air intake port 64 sucks the hot air from the upper end of the cabin 11 into the exhaust duct 52 and then discharges it. During cooling and dehumidification, the hot air is discharged. During heating and dehumidification, the movable block 6 is adjusted to correspond to the lowermost sealing component of the exhaust duct 52 to discharge the cold air. According to the dehumidification mode of the cabin 11, the hot and cold air can be quickly discharged, thereby improving the dehumidification efficiency of the cabin 11.

[0041] In the present invention, in order to avoid condensation in the prefabricated cabin, it is necessary to dehumidify the air in the prefabricated cabin. During dehumidification, the internal and external temperatures of the cabin body 11 are compared respectively according to two groups of temperature sensors 14, and then the controller 13 uses the semiconductor refrigeration plate 15 to heat and dehumidify or cool and dehumidify the inside of the cabin body 11 according to the temperature conditions. When the external temperature is high and the temperature inside the cabin is low, the semiconductor refrigeration plate 15 is started for cooling and dehumidification. When the external temperature is low and the temperature inside the cabin is high, the semiconductor refrigeration plate 15 is started for heating and dehumidification. When dehumidification, the fans inside the air inlet 21 and the air outlet 51 are started respectively, so that the air circulates in the cabin, facilitating air flow for dehumidification.

[0042] When the cabin 11 is cooled and dehumidified, the temperature outside the cabin 11 is high and the temperature inside is low (during the day), so the air sucked in by the air inlet 21 is hot air. Since the cabin 11 needs to be cooled, the air sucked in by the air inlet 21 needs to be cooled. At this time, the two sets of starting motors 3 will drive the two sets of driving plates 32 to rotate in opposite directions respectively. The rotation of the driving plates 32 will drive the connecting plates 33 to slide along the inner wall thereof. The movement of the connecting plates 33 will drive the first slide plate 35 to slide along the inner wall of the second slide plate 36. The wall slides, and at this time the driving plate 32 and the connecting plate 33 are in an inclined state, and because the first slide plate 35 is close to the inner wall of the air inlet pipe 22, the area of ​​the air flow is reduced, so that the hot air sucked in by the air inlet 21 has a faster flow rate when entering the air inlet pipe 22, so that the hot air can be cooled when passing through the air inlet pipe 22, so that when the cabin 11 is cooling and dehumidifying, the external hot air sucked in can be cooled, thereby improving the cooling efficiency of the cabin 11, thereby reducing the condensation phenomenon inside the cabin 11.

[0043] When the interior of the cabin 11 needs to be heated and dehumidified, the external temperature of the cabin 11 is low and the internal temperature is high (at night), so the air inlet 21 sucks in cold air. At this time, one of the motors 3 is started to drive the drive plate 32 to rotate until the connecting plate 33 drives the first slide plate 35 to contact the inner wall of the air inlet pipe 22. At this time, one of the first slide plates 35 will close half of the space inside the air inlet pipe 22. At this time, the multi-stage hydraulic cylinder 41 on the side where the first slide plate 35 contacts the inner wall of the air inlet pipe 22 is started. The multi-stage hydraulic cylinder 41 will drive the push block 42 to move downward. The movement of the push block 42 will drive the extrusion block 43 until the inclined surface of the extrusion block 43 contacts the outer wall of the fixed plate 31. At this time, the push block 42 continues to move downward. Since the drive plate 32 is in an inclined state at this time and has the same slope as the inclined surface of the extrusion block 43, the extrusion block 43 will be limited by the drive plate 32 during the downward movement. The extrusion block 43 squeezes the first spring 44 and slides from the inside to the outside along the inner wall of the push block 42. During the downward movement of the push block 42, the extrusion block 43 is completely in contact with the outer wall of the driving plate 32, so that a closed space is formed between the driving plate 32 and the first slide plate 35. The downward movement of the push block 42 squeezes the air in the closed space. At this time, the air pressure in the closed space increases, thereby increasing the air temperature inside the closed space. At this time, the driving motor 3 drives the first slide plate 35 to reset. At this time, the heated air enters the cabin 11 through the air inlet pipe 22 for heating. When one group of first slide plates 35 is reset, the other group of first slide plates 35 is driven to repeat the above steps, so that the two groups of first slide plates 35 alternately heat the air, and heat the inhaled cold air without affecting the air circulation, thereby helping the cabin 11 to heat up quickly and improving the heating and dehumidification effect.

[0044] When the air inlet 21 sucks in air, the exhaust port 51 is started synchronously to discharge the air. When cooling and dehumidifying, the hot air inside the cabin 11 needs to be discharged. At this time, the electric slider 61 is started to slide upward along the inner wall of the slide rail 62. The sliding of the electric slider 61 will drive the movable block 6 to move synchronously along the outer wall of the exhaust pipe 52 until the electric slider 61 drives the movable block 6 to reach the top of the exhaust pipe 52. Since two groups of second magnetic blocks 63 are fixedly installed on both sides of the movable block 6, the second magnetic block 63 will generate an attraction for the first magnetic block 55 inside the exhaust pipe 52. At this time, the first magnetic block 55 will be pulled by the second magnetic block 63, so that the first magnetic block 55 pulls the push plate 54 to squeeze the second spring 56 and slide along the inner wall of the exhaust pipe 52 from the inside to the outside, pushing The sliding of plate 54 will drive the sealing plate 53 to move synchronously, so that the two groups of sealing plates 53 move away from each other under the action of the two groups of first magnetic blocks 55. At this time, the upper end of the exhaust pipe 52 is in an open state. Since there is an air intake port 64 at the upper end of the movable block 6, the air intake port 64 will discharge the air at the upper end of the cabin 11 to the outside through the exhaust pipe 52. Since the air at the upper end of the cabin 11 is hot air, when the cabin 11 is cooled and dehumidified, the exhaust port 51 can quickly discharge the hot air inside the cabin 11. At the same time, when heating and dehumidifying are performed, it is only necessary to move the air intake port 64 to the lower end of the exhaust pipe 52 to quickly discharge the cold air inside the cabin 11, so that the exhaust port 51 can quickly discharge the hot and cold air according to the dehumidification mode of the cabin 11, thereby improving the dehumidification efficiency of the cabin 11.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
