Description

Technical Field

[0001] The invention relates to the technical field of marine power distribution cabinets, and in particular to a marine medium-voltage power distribution cabinet which is convenient for discharging water vapor. Background Art

[0002] Marine medium-voltage distribution cabinets are used to receive electrical energy from the main power supply or generator, and then distribute it to various electrical equipment on board, such as lighting, communication equipment, navigation equipment, etc. At the same time, the distribution cabinet can also control and protect the circuit to ensure the normal operation of electrical equipment. In order to better discharge the water vapor that may enter the distribution cabinet, marine medium-voltage distribution cabinets are usually designed with ventilation ducts to help remove the accumulated water vapor and maintain a dry environment inside the distribution cabinet;

[0003] Existing marine medium-voltage distribution cabinets usually adopt moisture-proof sealing design to ensure that external humid air cannot enter the equipment to reduce the accumulation of water vapor. First, the moisture-proof sealing design is adopted. In order to prevent external humid air from entering the equipment, the sealing design usually adopts better sealing materials and processes. These sealing materials will greatly reduce the air circulation and affect the free flow of air. Poor air circulation will cause the internal heat to be unable to be effectively dissipated, resulting in temperature rise and increase in the operating temperature of the equipment, affecting the stability and service life of the equipment;

[0004] Compared with the existing marine medium-voltage power distribution cabinets that use a fixed distribution method to install electrical components, the fixed distribution method will cause the gaps between some electrical components to be smaller and the sealing to be poor. When the power distribution cabinet is heat-dissipating, the internal and external air will continue to circulate. At this time, the external humid air will enter the cabinet, mix with the internal hot air and condense into water vapor, which will cause heat accumulation in some areas, affecting the heat dissipation effect of the equipment and increasing the risk of equipment overheating. In addition, the fixed distribution method will lead to unreasonable use of space between electrical components, resulting in space waste or difficulty in installing more components, limiting the expansion capacity of the equipment. In addition, the fixed distribution installation method of electrical components will also make some components difficult to maintain and replace. If a component needs to be repaired or replaced, due to the fixed distribution layout, other components need to be moved to operate, which increases the difficulty and workload of maintenance;

[0005] In view of this, the present invention proposes a marine medium-voltage power distribution cabinet that is convenient for discharging water vapor to compensate for and improve the shortcomings of the prior art. Summary of the invention

[0013] Furthermore, the dehumidification plates are made entirely of activated carbon material, each group of the dehumidification plates is composed of three circular plates, and trapezoidal grooves are provided through the surfaces of the dehumidification plates.

[0014] Furthermore, the second positive magnetic rods are all located on the movement path of the first positive magnetic rods, and the second positive magnetic rods are initially contracted inside the processing chamber.

[0015] Furthermore, the ventilation separation mechanism includes a driving cylinder symmetrically installed on the inner wall of the distribution cabinet body, the output shaft end of the driving cylinder is fixedly connected to a movable plate, and a fixed shaft is installed on the side of the movable plate close to the electrical component, the fixed shaft is fixedly connected to the rear side wall of the electrical component, the rear side wall of the electrical component is rotatably connected to a hinge group, the rear side wall of the electrical component is evenly fixedly connected to a positioning frame, and the interior of the positioning frame is slidably connected to a cylindrical shaft.

[0016] Furthermore, the entire driving cylinder is electrically connected to the main control compartment, a sliding groove is provided on the surface of the movable plate in an inclined manner, and the movable plate is slidably connected to the fixed shaft through the sliding groove.

[0017] Furthermore, the hinge group is composed of a combination of no less than eight hinged plates, with two hinged plates forming a group, and the ends of each group of hinged plates that are close to each other are rotatably connected through a convex shaft, and universal balls are symmetrically installed inside the positioning frame, and arc grooves are provided at the positions of the cylindrical shafts corresponding to the universal balls.

[0018] Furthermore, the protective buffer mechanism includes a sliding shaft uniformly fixedly connected to the outer wall of the distribution cabinet body, the end of the sliding shaft away from the distribution cabinet body is fixedly connected to a stress plate, the outer wall of the sliding shaft is uniformly sleeved with a buffer spring, the interior of the distribution cabinet body is symmetrically fixedly connected with a vertical shaft, the outer wall of the vertical shaft is symmetrically slidably connected with an expansion frame, and the outer walls of the vertical shafts are all sleeved with stress springs.

[0019] Furthermore, one end of the expansion frame away from the vertical axis is fixedly connected to the stress plate, and the expansion frames are initially in a mutually contracted state.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The device first limits and shrinks the range of air flow through the air inlet pipe installed outside the main body of the distribution cabinet, and then dehumidifies the air through the dehumidification plate inside the purification cylinder. By performing dehumidification at the exhaust port of the main body of the distribution cabinet, water vapor can be effectively prevented from entering the interior. Humid air contains corrosive substances such as salt, which will accelerate the corrosion rate of electrical equipment after entering the main body of the distribution cabinet. Dehumidification can effectively prevent water vapor from entering, thereby reducing the possibility of equipment corrosion and extending the service life of the main body of the distribution cabinet;

[0022] Secondly, since the device installs the dehumidification plate and the telescopic rod in the processing chamber, it can move downward in time according to the gravity effect of a certain circular plate in the dehumidification plate after it is saturated with adsorption, and then automatically replace the unsaturated dehumidification plate to continue the moisture absorption treatment, thereby improving the problem of the long adsorption time of the dehumidification plate of the device. The automatic replacement of the unsaturated dehumidification plate can ensure the continuous operation of the entire device, and will not stop working due to the adsorption saturation of a part of the dehumidification plate, thereby maintaining the humidity in the air at a low level. At the same time, the method of automatically replacing the new dehumidification plate with the telescopic rod can also reduce the labor intensity and maintenance costs of the staff, and avoid a series of complex operations that require manual participation in the equipment shutdown and then replacement;

[0023] Finally, the staff can judge whether the dehumidification plate inside the processing bin is in the adsorption saturation state and then replace it by observing the sliding out of the second positive magnetic rod on the side wall of the processing bin. This method not only does not need to disassemble the entire processing bin to judge the material saturation, but also does not require the staff to approach the main working range of the power distribution cabinet to find the saturation state of the dehumidification plate. At the same time, the staff can take corresponding maintenance measures in advance according to the distance the second positive magnetic rod moves out, thereby avoiding equipment failure and improving the reliability and stability of the equipment. The saturation time of the dehumidification plate can be grasped according to the distance the second positive magnetic rod moves out, and the maintenance cycle can be adjusted according to the actual situation, and the subsequent equipment can be avoided from running for a long time, thereby reducing energy waste and reducing energy consumption.

[0024] Among them, since the overall size ratio between the ventilation pipe, the purification tube and the air inlet pipe is 2:1:2, by setting the size ratio of pipes of different sizes, the distribution and uniformity of air flow can be optimized to avoid local poor ventilation or dead corners. Specifically, the ends of the ventilation pipe and the air inlet pipe that are far away from each other expand outward, and the ends that are close to each other shrink inward. First, the larger size of the air inlet pipe can effectively inhale more external air to improve the ventilation effect, while the relatively small size of the purification tube can increase the time and contact area for moisture absorption treatment of the air to improve the purification efficiency. At the same time, the small size of the purification tube also helps to control the size and cost of moisture absorption components. Finally, the larger size of the ventilation pipe can reduce the resistance to air flow to the inside of the main body of the distribution cabinet, thereby reducing energy loss and improving the energy efficiency performance of the ventilation system.

[0025] Among them, since the surface of each group of dehumidification plates is penetrated with trapezoidal grooves, the specific form of the trapezoidal grooves is expansion at the air inlet end and contraction at the air outlet end, the flow path and speed of the airflow can be changed by opening the trapezoidal grooves. The expanded trapezoidal grooves at the air inlet end can expand the airflow cross-sectional area and reduce the airflow speed to ensure that the dehumidification plate as a whole fully absorbs moisture, while the contracted trapezoidal grooves at the air outlet end can contract the airflow cross-sectional area and increase the airflow speed, thereby ensuring the rate of alternating air circulation inside and outside the main body of the power distribution cabinet;

[0026] (2) The device can synchronously drive the movable plate downward by extending the driving cylinder, thereby ensuring that the electrical components are equidistantly separated when the main body of the distribution cabinet is started. Conversely, by contracting the driving cylinder, it can also ensure that the electrical components are restored to their original state and remain in close contact when the main body of the distribution cabinet is closed. Compared with the existing equipment that uses a fixed distribution method to install electrical components, the device starts the main body of the distribution cabinet to disperse the working electrical components equidistantly inside the main body of the distribution cabinet to avoid the generation of concentrated heat. At the same time, it cooperates with the normal operation of the driving fan to ensure that the air flows more smoothly between the electrical components and increases the contact area between the electrical components when the wind flows, thereby reducing the risk of equipment failure caused by overheating inside the equipment. In addition, after the device stops using, the electrical components are restored to their initial close contact state by contracting the electrical components, thereby improving the overall stability of the main body of the distribution cabinet and reducing the risk of looseness and failure of the main body of the distribution cabinet during ship operation;

[0027] Among them, Figure 7 As shown, since the hinge group is specifically composed of a combination of no less than eight hinge plates, and each hinge plate is a group of two, and the ends of each group of hinge plates that are close to each other are rotatably connected through a convex shaft, when the electrical components are formally separated at equal distances, the hinge group will change from the initial contracted state to the state of expansion to the left and right sides. At this time, according to the expansion state of the hinge group after the electrical components are separated, the hinge group of the rear side wall of each electrical component presents a triangular structure, and according to the characteristics of the triangular structure, the pressure on the electrical components can be evenly distributed to various parts of the hinge group, thereby reducing local stress, improving the bearing capacity and stability of the electrical components, and reducing vibration and noise generated during operation. At the same time, relative to the overall center symmetry of the hinge group after the electrical components are separated, a parallelogram state is formed, and according to the characteristics of the quadrilateral structure, the electrical components have a certain flexibility when moving, thereby enabling them to adapt to deformation and deflection within a certain range;

[0028] Among them, Figure 8 As shown, by symmetrically installing the universal ball inside the positioning frame, and then cooperating with the arc groove on the outer wall of the cylindrical shaft to keep the two in sliding connection, this connection structure has strong adaptability and can tolerate the deviation between the connection parts to a certain extent, which helps to reduce assembly errors. First, the universal ball is slidably connected in the arc groove to achieve multi-directional contact free sliding, and thus can adapt to various complex motion forms of the main body of the distribution cabinet ship. Secondly, the sliding connection in the arc groove can reduce the friction resistance of the universal ball when it moves, which is beneficial to reduce the wear of the connection and extend the service life. Finally, according to the characteristics of the overall sphere of the universal ball, relying on the smooth outer wall of the sphere, it can rotate freely in multiple directions during movement, thereby absorbing and dispersing part of the vibration and impact force to reduce the impact transmitted to other components, so that it can absorb vibration and impact to a certain extent when moving, thereby improving the stability and comfort of the equipment;

[0029] (3) Based on the analysis of the stress frequency of the overall area of ​​the distribution cabinet body, the device symmetrically installs stress plates on the left and right sides of the distribution cabinet body. Compared with the prior art that uses specially designed vibration isolation brackets and uses shock-absorbing materials to reduce the vibration transmission between the equipment and the hull, the device first uses the horizontally installed buffer spring to rely on its own elastic force to slow down the stress plate. Secondly, it uses the expansion frame that expands after being stressed to convert the horizontal extrusion force on the left and right sides of the distribution cabinet body into vertical transmission. By changing the stress direction of the extrusion force, the extrusion force on the electrical components and other parts inside the distribution cabinet body can be reduced to avoid the impact and damage risks caused by the shaking and vibration of the ship. Compared with taking complex methods to reduce the extrusion force, changing the stress direction is easier to implement and maintain. It does not require additional devices or systems to reduce the extrusion force, but realizes the stress direction through reasonable structural design. In addition, changing the stress direction in the device can make the distribution cabinet body better adapt to various extrusion situations. No matter which area on the left or right ends the pressure acts on, it can be guided to a safe position through the expansion frame to provide more comprehensive protection.

[0043] Embodiments of the present invention

[0044] Please refer to Figure 1 - Figure 2 As shown, a medium-voltage distribution cabinet for ships that facilitates the discharge of water vapor includes a distribution cabinet body 1, a plurality of groups of electrical components 11 are evenly installed inside the distribution cabinet body 1, a main control compartment 12 is installed above the electrical components 11, a driving fan 13 is rotatably connected to the rear side wall of the main control compartment 12, an air dehumidification mechanism 2 is arranged on the rear side wall of the main control compartment 12, a ventilation separation mechanism 3 is arranged on the rear side wall of the electrical components 11, and protective buffer mechanisms 4 are symmetrically arranged on both sides of the distribution cabinet body 1

[0045] Please refer to Figure 2 - Figure 6As shown, the air dehumidification mechanism 2 includes a ventilation pipe 21 connected to the rear side of the driving fan 13, the end of the ventilation pipe 21 away from the driving fan 13 is connected to a processing chamber 22, three telescopic rods 23 are evenly fixedly connected above the processing chamber 22, the lower ends of the three telescopic rods 23 are all fixedly connected to a dehumidification plate 24, a purification cylinder 25 is slidably connected below the dehumidification plate 24, and a recovery chamber 26 is evenly connected below the purification cylinder 25, and an end of the purification cylinder 25 away from the ventilation pipe 21 is connected to an air inlet pipe 27, and the outer wall of the purification cylinder 25 is symmetrically fixedly connected with a cylindrical convex shaft 28, and a limiting groove 29 is provided at the position of the inner wall of the processing chamber 22 corresponding to the cylindrical convex shaft 28. The telescopic parts of the rod 23 are fixedly connected with the first positive magnetic rod 210, and the interior of the processing chamber 22 is evenly fixedly connected with the second positive magnetic rod 211. The overall size ratio between the ventilation pipe 21, the purification cylinder 25 and the air inlet pipe 27 is 2:1:2. The ends of the ventilation pipe 21 and the air inlet pipe 27 that are away from each other expand outward, and the ends that are close to each other shrink inward. The dehumidification plate 24 is made of activated carbon material as a whole. Each group of dehumidification plates 24 is composed of three circular plates, and the surface of the dehumidification plate 24 is penetrated by a trapezoidal groove. The second positive magnetic rod 211 is located on the movement path of the first positive magnetic rod 210, and the second positive magnetic rod 211 is initially contracted inside the processing chamber 22.

[0046] Specifically, the dehumidification process can effectively prevent humid air from entering and keep the interior of the marine medium-voltage distribution cabinet body 11 dry, which helps prevent water vapor from entering the electrical equipment and reduce the risk of the equipment getting damp. Humid air may contain corrosive substances such as salt, which will accelerate the corrosion rate of the electrical equipment after entering the distribution cabinet body 11. The dehumidification process can effectively prevent water vapor from entering and reduce the possibility of equipment corrosion.

[0047] Please refer to Figure 7 - Figure 8 As shown, the ventilation separation mechanism 3 includes a driving cylinder 31 symmetrically installed on the inner wall of the power distribution cabinet body 1, the output shaft end of the driving cylinder 31 is fixedly connected to a moving plate 32, and a fixed shaft 33 is installed on the side of the moving plate 32 close to the electrical component 11, and the fixed shafts 33 are all fixedly connected to the rear side wall of the electrical component 11, and the rear side wall of the electrical component 11 is rotatably connected to a hinge group 34, and the rear side wall of the electrical component 11 is evenly fixedly connected to a positioning frame 35, and the interior of the positioning frame 35 is slidably connected to a cylindrical shaft 36, and the driving cylinder 31 as a whole is electrically connected to the main control warehouse 12, and a sliding groove is inclined on the surface of the moving plate 32, and the moving plate 32 is slidably connected to the fixed shaft 33 through the sliding groove, and the hinge group 34 is composed of a combination of not less than eight hinged plates, and each hinged plate is a group of two, and the ends of each group of hinged plates close to each other are rotatably connected through a convex shaft, and a universal ball is symmetrically installed inside the positioning frame 35, and an arc groove is opened at the position of the cylindrical shaft 36 corresponding to the universal ball;

[0048] Specifically, the electrical components 11 are equally dispersed to maintain heat dissipation, which can avoid the generation of concentrated heat. When the electrical components 11 are attached together, heat sharing and balanced heat dissipation can be maintained, which helps to maintain the temperature stability of the components, reduce vibration and noise generated during transportation and closing, and improve the comfort and safety of the ship.

[0049] Please refer to Fig. 9 - Fig.11 As shown, the protective buffer mechanism 4 includes a sliding shaft 42 uniformly fixedly connected to the outer wall of the distribution cabinet body 1, the end of the sliding shaft 42 away from the distribution cabinet body 1 is fixedly connected to the stress plate 41, the outer wall of the sliding shaft 42 is uniformly sleeved with a buffer spring 43, the interior of the distribution cabinet body 1 is symmetrically fixedly connected with a vertical shaft 44, the outer wall of the vertical shaft 44 is symmetrically slidably connected with an expansion frame 45, the outer wall of the vertical shaft 44 is sleeved with a stress spring 46, the end of the expansion frame 45 away from the vertical shaft 44 is fixedly connected to the stress plate 41, and the expansion frame 45 is initially in a mutually contracted state.

[0050] Specifically, by changing the force direction of the extrusion force, the electrical components 11 inside the power distribution cabinet body 1 can be more evenly stressed, thereby improving the stability of the equipment under the shaking and vibration of the ship. Reducing the effect of the extrusion force can extend the service life of the electrical components 11 and the power distribution cabinet body 1, and reduce the wear and damage of the equipment caused by excessive force.

[0051] The following are the complete usage steps and working principles of the above embodiment:

[0052] The air dehumidification mechanism 2 used for timely purifying the air entering the power distribution cabinet body 1 and the internal air of the electrical components 11 is specifically used as follows:

[0053] like Figure 2 and Figure 3 As shown, the ventilation duct formed by the ventilation pipe 21, the processing chamber 22 and the air inlet pipe 27 is installed as a whole at the ventilation position of the driving fan 13 inside the main control chamber 12. Therefore, when the power distribution cabinet body 1 is in a normal working state and the driving fan 13 is continuously rotated to maintain internal and external ventilation, the air outside the electrical component 11 can only enter the processing chamber 22 from the position of the air inlet pipe 27, and then flow through the ventilation pipe 21 before finally entering the inside of the power distribution cabinet body 1;

[0054] like Figure 4As shown, this figure specifically shows the initial state of the internal structure of the processing chamber 22. At this time, the lowest circular plates of the dehumidification plates 24 are all located inside the purification cylinder 25. Therefore, when air enters the inside of the distribution cabinet body 1 from the outside through the position of the purification cylinder 25, the dehumidification plates 24 composed of activated carbon material as a whole will fully absorb the water vapor in the air and dehumidify it. Since each dehumidification plate 24 is composed of a combination of three circular plates, and the processing chamber 22 is slidably connected to the inside of the processing chamber 22 through the telescopic rod 23, when the dehumidification plate 24 initially located inside the purification cylinder 25 tends to be saturated after a long period of moisture absorption treatment, it will gradually drive the telescopic rod 23 to expand and contract according to its own gravity, so as to move itself to the inside of the recovery chamber 26, and ensure that the dehumidification plate 24 that has not been subjected to moisture absorption treatment moves to the inside of the purification cylinder 25, thereby achieving the effect of automatically replacing the dehumidification plate, so that the inside of the purification cylinder 25 is in a state of continuous adsorption of water vapor;

[0055] like Figure 6 As shown, since the first positive magnetic rod 210 is fixedly connected to the retractable part of the telescopic rod 23, and the second positive magnetic rod 211 is located on the movement path of the first positive magnetic rod 210, when the entire dehumidification plate 24 is in adsorption saturation, the uppermost circular plate in the dehumidification plate 24 will gradually move downward, and the first positive magnetic rod 210 and the second positive magnetic rod 211 will correspond to each other. Since the second positive magnetic rod 211 is initially contracted inside the processing bin 22, when the first positive magnetic rod 210 and the second positive magnetic rod 211 remain corresponding, the second positive magnetic rod 211 itself will be moved to the outside of the processing bin 22 by the magnetic repulsion force of the first positive magnetic rod 210. Therefore, the staff does not need to disassemble the processing bin 22, and only needs to observe the movement of the second positive magnetic rod 211 outside the overall working range of the power distribution cabinet body 1 to determine whether the dehumidification plate 24 inside the processing bin 22 is in an adsorption saturation state, and then replace the dehumidification plate 24 in time;

[0056] like Figure 5 As shown, since the outer wall of the purification cylinder 25 is symmetrically fixedly connected with the cylindrical convex shaft 28, and the inner wall of the processing chamber 22 is provided with a limiting groove 29 at the position corresponding to the cylindrical convex shaft 28, when the staff subsequently replaces the dehumidification plate 24 inside the processing chamber 22, they only need to simply pull the purification cylinder 25 to realize the separation operation of the purification cylinder 25 and the processing chamber 22, thereby improving the convenience of replacement;

[0057] When the power distribution cabinet body 1 is used, the ventilation separation mechanism 3 for separating multiple groups of electrical components 11 at equal distances is specifically used as follows:

[0058] like Figure 7As shown, since the driving cylinder 31 is electrically connected to the main control compartment 12 as a whole, the driving cylinder 31 will be started simultaneously with the power distribution cabinet body 1. Since the left and right ends of the moving plate 32 are fixedly connected to the output shaft end of the driving cylinder 31, and the surface of the moving plate 32 is inclined with a slide groove, when the driving cylinder 31 is started, the moving plate 32 will move downward synchronously with it. In the process of the moving plate 32 moving downward, the inner wall of the slide groove will continuously squeeze the fixed shaft 33, so that the fixed shaft 33 drives the electrical component 11 to move. The wall is slidably connected to the outer wall of the cylindrical shaft 36 through the positioning frame 35. Therefore, when the above-mentioned moving plate 32 moves downward, the electrical component 11 will be squeezed by the slide groove and will specifically move linearly along the outer wall of the cylindrical shaft 36, so that the electrical components 11 inside the power distribution cabinet body 1 are kept separated in time after the equipment is started. On the contrary, when the equipment is stopped and the output end of the driving cylinder 31 is restored to its original position, the moving plate 32 as a whole will drive the electrical components 11 to move in the above-mentioned reverse direction, so that the electrical components 11 inside the power distribution cabinet body 1 are kept in close contact in time after the equipment is turned off;

[0059] The protective buffer mechanism 4 used to change the overall force direction of the power distribution cabinet body 1 and thus protect it is specifically used as follows:

[0060] When a ship is sailing at sea, it will be affected by the natural environment such as waves and wind, causing the hull to shake and vibrate. This movement will produce impact force on the left and right sides of the distribution cabinet body 1. Especially in bad weather and sea conditions, the shaking and vibration will be greater. Fig. 9 and Fig.10 As shown, the stress plates 41 are symmetrically slidably connected to the left and right sides of the power distribution cabinet body 1 through the sliding shaft 42. Therefore, when the left and right sides of the power distribution cabinet body 1 are squeezed in the above situation, firstly, according to the buffering force of the buffer spring 43 sleeved on the outer wall of the sliding shaft 42, the transmission of the squeezing force on the stress plate 41 in the horizontal direction can be weakened. Fig.11 As shown, since the interior of the power distribution cabinet body 1 is symmetrically fixedly connected with the vertical shaft 44, and the outer wall of the vertical shaft 44 is symmetrically slidably connected with the expansion frame 45, and the end of the expansion frame 45 away from the vertical shaft 44 is fixedly connected to the stress plate 41, when the stress plate 41 relies on the buffering force of the buffer spring 43 to reduce the transmission of its own extrusion force, the extrusion force on the stress plate 41 will simultaneously act on the surface of the expansion frame 45, thereby converting the expansion frame 45, which is initially in a mutually contracted state, into a state as shown in FIG. Fig.11As shown in the state of expansion to the upper and lower sides, since the outer walls of the vertical shaft 44 are sleeved with stress springs 46, and the upper and lower ends of the stress springs 46 are fixedly connected to the expansion frame 45, when the expansion frame 45 moves and expands in the upper and lower directions at the same time, the stress springs 46 will be continuously stretched to reduce the extrusion force on itself, and the extrusion force on itself in the horizontal direction will be converted and transmitted to the vertical direction through the expansion direction of the expansion frame 45.
