Description
Technical Field
[0001] This invention belongs to the field of power distribution cabinet technology, specifically relating to a JP complete power distribution cabinet. Background Technology
[0002] JP complete switchgear is a new type of integrated control box that integrates power distribution, metering, protection, control, and reactive power compensation. Switchgear is divided into power switchgear, lighting switchgear, and metering cabinet. It is the final stage equipment of the power distribution system. Switchgear is a general term for motor control center. Switchgear is used in situations where the load is relatively dispersed and there are few circuits. Motor control center is used in situations where the load is concentrated and there are many circuits. They distribute the power of a certain circuit of the previous stage of power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.
[0003] When existing distribution cabinets are working normally, their structures release a large amount of heat. In order to maintain a suitable temperature in the distribution cabinet, multiple ventilation holes are usually reserved on the distribution cabinet to discharge excess heat and prevent the temperature inside the distribution cabinet from rising continuously. However, there are many problems, such as: the cooling efficiency is easily affected by weather factors, and while the ventilation holes allow air to pass through, liquid and pollutant particles can easily enter with the airflow. Therefore, a JP complete distribution cabinet is proposed. Summary of the Invention
[0004] This invention provides a JP complete power distribution cabinet, the purpose of which is to solve the problem that when the existing power distribution cabinet is working normally, the structure inside releases a lot of heat energy. In order to maintain a suitable temperature in the power distribution cabinet, multiple ventilation holes are generally reserved on the power distribution cabinet to discharge excess heat energy and prevent the temperature inside the power distribution cabinet from rising continuously. However, there are many problems, such as: the cooling efficiency is easily affected by weather factors, and the ventilation holes can easily allow liquid and pollutant particles to enter with the airflow.
[0005] This invention provides a JP complete power distribution cabinet, including a housing, characterized in that a receiving cavity is reserved on the inner side of the housing, a temperature control platform is installed on the inner side of the receiving cavity, a plurality of mounting brackets are provided on one side of the inner side of the temperature control platform, a plurality of temperature conductive plates are provided on the side of the temperature control platform near the inner side of the receiving cavity, the temperature conductive plates are wavy and are composed of a plurality of semi-circular rings spliced together, and a plurality of communication holes are milled on one side of the temperature control platform, the center of the communication holes coinciding with the center of the semi-circular arc of the temperature conductive plate;
[0006] The temperature control platform has a solution chamber reserved on its inner side, which contains a heat preservation liquid. On the other side of the temperature control platform, several external channels are reserved. Each communication hole corresponds to an external channel. Each communication hole is connected to a corresponding external channel by a connecting pipe. The connecting pipe passes through the inner side of the solution chamber and is immersed in the heat preservation liquid.
[0007] A side chamber is provided on the outer side of the temperature control platform, and an air intake chamber is formed between the side chamber and the temperature control platform. The side chamber protrudes outward, and one surface of the air intake chamber on the side chamber is a spherical surface. The spherical surface of the air intake chamber is opposite to the outer surface of the temperature control platform. A second sieve is provided at the bottom of the air intake chamber. The air intake chamber faces downward. A first motor is installed on the lower side inside the air intake chamber. The first motor faces obliquely upward, and a second paddle is provided on the rotating rod of the first motor.
[0008] By adopting the above scheme, the wavy shape of the heat-conducting plate increases the surface area of the heat-conducting plate, thereby increasing the efficiency of absorbing heat energy inside the containment cavity and the heat release efficiency inside the solution cavity, thus achieving the purpose of avoiding a sharp rise in temperature inside the containment cavity. Since the air intake cavity faces downward, rainwater and pollutant particles are difficult to enter the containment cavity through the air intake cavity under the action of gravity.
[0009] Furthermore, the heat-insulating liquid consists of 10 parts solvent and 3 parts calcium chloride, and its freezing point is -55 degrees Celsius.
[0010] By adopting the above scheme, the calcium chloride solution has the characteristics of high specific heat capacity and low freezing point. When a large amount of heat is generated in the containment cavity, the heat-insulating liquid in the temperature control platform and friction wheel II can quickly absorb the heat energy, avoiding a sharp rise or fall in the temperature in the containment cavity, thus enabling the electrical cabinet to adapt well to harsh environments.
[0011] Furthermore, the communication hole is horizontally positioned, the outer channel is angled, the end of the outer channel closer to the connecting pipe is higher than the end of the outer channel farther from the connecting pipe, and the connecting pipe is curved.
[0012] By adopting the above scheme, due to the inclined placement of the outer channel, under the action of gravity, it is difficult for liquid to enter the communication hole and the receiving cavity through the outer channel and the connecting pipe.
[0013] Furthermore, a VC heat sink is connected to the top of the temperature control platform. The VC heat sink is in the shape of a "7". A heat dissipation block is fixedly connected to the top of the VC heat sink. One end of the heat dissipation block is connected to a liquid bottle. The heat dissipation block is located inside the liquid bottle. The heat dissipation block is made of silver. The inside of the VC heat sink is a vacuum chamber. A polyethylene capillary tube is installed inside the vacuum chamber. The polyethylene capillary tube connects to both ends of the inner cavity of the VC heat sink. The inside of the VC heat sink contains a medium liquid.
[0014] By adopting the above scheme, the VC heat sink can conduct the heat energy absorbed at the temperature control platform to the heat dissipation block, and then transfer it to the liquid bottle through the heat dissipation block, so that the liquid in the liquid bottle is heated, the liquid in the liquid bottle evaporates, and the temperature in the container cavity is reduced. It can also cause the liquid in the liquid bottle to solidify, melt, and evaporate.
[0015] Furthermore, the outer circumferential surface of the housing is provided with several hinges, the closed cover is connected to the housing, and the ends of all the hinges away from the housing are fixedly connected to the same closed cover. The inner top wall of the closed cover is provided with a second motor, and a first paddle is installed on the rotating rod of the second motor. A liquid bottle is pre-set on the top of the closed cover. Several second central pillars are installed on the inner side of the closed cover. The second motor is placed at an angle. Two limiting cylinders are fixedly connected to the inner side of the closed cover. A squeezing cylinder and a sliding table are also installed on the inner side of the closed cover. The sliding table and the second motor are connected by wires.
[0016] The inner side of the extrusion cylinder is connected to a first connecting column, and the lower side of the first connecting column is fixedly connected to an elastic element. The elastic element abuts against the bottom wall of the inner side of the extrusion cylinder. The upper end of the first connecting column is inserted into the lower end of the inner side of the liquid bottle. The limiting cylinder and the intermediate column are fitted with a clearance.
[0017] A central column is rotatably connected to the inner side of the closed cover. One end of the central column is inserted into and fixed to the inner side of the friction wheel. The central column is fixed to one end of the shielding cover. One side of the intermediate column is frictionally connected to the outer side of the friction wheel. The outer side of the friction wheel is frictionally connected to the other side of the intermediate column. A ventilation channel is reserved at the end of the shielding cover away from the central column. There are several central columns and shielding covers. The shielding cover extends into a large square hole and divides the large square hole into several small square holes. A large sieve is provided on the side of the closed cover away from the large square hole. The large sieve connects the inner side of the closed cover with the inner side of the machine casing.
[0018] By adopting the above scheme, the airflow generated by the first impeller blows outward, while the shielding cover is placed at an angle, making it difficult for external fluid to enter the receiving cavity through the square hole. The first linkage column drives the second friction wheel to rotate, the second friction wheel moves the middle column, the middle column rotates the first friction wheel, the first impeller rotates the first center column, and the housing controls the shielding cover to swing, changing the angle between the shielding cover and the horizontal plane.
[0019] Furthermore, a rubber ring is provided on the outer periphery of the liquid bottle, and the rubber ring and the linkage are interference-fitted, and the Ra value on the inner side of the liquid bottle is below 0.4.
[0020] By adopting the above solution, the rubber ring on the head of the liquid bottle seals the top of the linkage column one and allows the liquid bottle to move smoothly inside the linkage column one.
[0021] Furthermore, a crossbeam is provided on one side of the first linkage column, and a linkage frame is rotatably connected to the end of the crossbeam away from the first linkage column. One end of the linkage frame is connected to the sliding table. A sliding cavity is recessed on the inner side of the sliding table. The sliding cavity and the slider are movably connected. One end of the slider and the linkage frame are hinged. A variable resistor is provided on one side of the inner side of the sliding cavity. The variable resistor is made of graphite. A slider is installed on the upper side of the slider. The outer side of the slider is in close contact with the outer side of the variable resistor. The slider and the variable resistor are connected to the same wire. The wire is electrically connected to the second motor. A middle column is inserted into the inner side of the limiting cylinder. The middle column and the limiting cylinder are movably connected. The outer side of the first linkage column is in frictional contact with the outer circumferential surface of the second friction wheel. A friction plate is provided on each of the two sides of the middle column. One friction plate is connected to the first friction wheel, and the other friction plate is connected to the second friction wheel.
[0022] By adopting the above scheme, the intermediate column can simultaneously drive the three friction wheels to rotate, while controlling the angle between the shielding cover and the horizontal plane.
[0023] Furthermore, the liquid bottle and the outer side of the machine housing are angled, and several small square holes are reserved on the side of the liquid bottle away from the machine housing, and the small square holes are adapted to the shielding cover.
[0024] By adopting the above solution, due to the angled position of the cap, some liquid is drawn into the inside of the container.
[0025] Furthermore, a sieve is installed on the inner side of the ventilation channel, and the shielding cover is placed at an angle.
[0026] By adopting the above method, the angled placement of the shielding cover can reduce the amount of liquid entering the inside of the sealed cover.
[0027] Furthermore, the outer side of the shielding cover away from the closing cover is curved.
[0028] By adopting the above solution, the ventilation channel can still communicate with the outside world even when the small opening is covered and closed.
[0029] Furthermore, the two central pillars are parallel to each other, and the rotation center lines of all the two central pillars are located in the same plane. The two central pillars and the two friction wheels are connected by insertion.
[0030] By adopting the above scheme, the central column 2 allows all friction wheels 2 to be in close contact with the same plane of 19) at the same time, and thus can be synchronously driven by the linkage column 1.
[0031] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects:
[0032] 1. In this invention, by using a temperature control platform, the wavy shape of the temperature-conducting plate increases the surface area of the temperature-conducting plate, thereby increasing the efficiency of absorbing heat energy inside the containment cavity and the heat release efficiency inside the solution cavity. The calcium chloride solution inside the friction wheel has the characteristics of large specific heat capacity and low freezing point. When a large amount of heat is generated inside the containment cavity, the heat-insulating liquid can quickly absorb the heat energy, avoiding a sharp rise or fall in the temperature inside the containment cavity. This allows the electrical cabinet to adapt well to harsh environments. In addition, the temperature control platform itself has good thermal conductivity, which can cool the inside of the containment cavity.
[0033] 2. In this invention, the liquid accumulates on the inside of the liquid bottle. Under the action of gravity, the liquid bottle is squeezed and pushed to move the linkage column 1 and the elastic element. During the movement, the linkage column 1 drives several friction wheels 2 to rotate synchronously through friction. The friction wheels 2 drive the middle column to move through friction. The middle column drives the friction wheel 1 to rotate. The friction wheel 1 drives the central column 1 to rotate. The central column 1 controls the shielding cover to change its angle with the horizontal plane. After the rainfall occurs, the rainfall itself will cool and lower the temperature of the casing, thereby reducing the airflow size. This causes the shielding cover to reduce the size of the channel connecting the square hole to the outside, thereby further reducing the liquid from entering the inside.
[0034] 3. In this invention, by using VC heat sink and heat dissipation block, the VC heat sink can conduct the heat energy absorbed at the temperature control platform to the heat dissipation block, and then transfer it to the liquid bottle through the heat dissipation block, so that the liquid in the liquid bottle is heated, the liquid in the liquid bottle evaporates and the temperature in the container cavity is reduced, and the liquid in the liquid bottle can be melted and evaporated after solidification, continuously supplying heat energy to the liquid bottle, continuously causing the liquid in the liquid bottle to evaporate, thereby enabling the linkage column one and the shielding cover to automatically retract, increasing the channel for the square hole to communicate with the outside, increasing the airflow generated by motor two and blade one, increasing the airflow through the container cavity, and improving the cooling efficiency;
[0035] 4. In this invention, the airflow generated by the paddle blows outward, while the cover is placed at an angle, making it difficult for external fluids to enter the receiving cavity through the square hole, thus keeping the receiving cavity dry.
[0036] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0047] like Figure 1-7As shown, this invention proposes a JP complete power distribution cabinet, including a housing 12. Several hinges 13 are arranged on the outer periphery of the housing 12. A sealing cover 15 is connected to the housing 12. The ends of all hinges 13 away from the housing 12 are fixedly connected to the same sealing cover 15. A motor 17 is arranged on the inner top wall of the sealing cover 15. A liquid bottle 14 is obliquely positioned on the outer side of the housing 12. Several small square holes are reserved on the side of the liquid bottle 14 away from the housing 12, and these small square holes are adapted to a shielding cover 22. Due to the oblique position of the sealing cover 15, some liquid gathers inside the liquid bottle 14. A paddle 18 is installed on the rotor of the motor 17. The liquid bottle 14 is pre-set on the top of the sealing cover 15. Several central columns 26 are installed on the inner side of the sealing cover 15. The motor 17 is obliquely positioned.
[0048] The two central columns 26 are parallel to each other, and the rotation center lines of all the two central columns 26 are located in the same plane. The two central columns 26 are inserted into the friction wheel 25. The two central columns 26 enable all the friction wheels 25 to be in close contact with the same plane at the same time. Two limiting cylinders 24 are fixedly connected to the inside of the sealing cover 15. The inside of the sealing cover 15 is also equipped with a squeezing cylinder 27 and a sliding platform 16. The sliding platform 16 and the motor 17 are connected by a wire. The inside of the squeezing cylinder 27 is inserted into the connecting column 19. The lower side of the connecting column 19 is fixedly connected to an elastic element 28. The elastic element 28 abuts against the bottom wall of the inside of the squeezing cylinder 27. The upper end of the connecting column 19 is inserted into the lower end of the liquid bottle 14.
[0049] A rubber ring is provided on the outer periphery of the liquid bottle 14. The rubber ring and the linkage column 19 are interference-fitted. The Ra value of the inner side of the liquid bottle 14 is below 0.4. This seals the top of the linkage column 19 and allows the liquid bottle 14 to move smoothly. A crossbeam 31 is provided on one side of the linkage column 19. A linkage frame 30 is rotatably connected to the end of the crossbeam 31 away from the linkage column 19. One end of the linkage frame 30 is connected to the sliding table 16. The inner side of the limiting cylinder 24 is inserted into the intermediate column 32. The intermediate column 32 and the limiting cylinder 24 are movably connected. The outer side of the linkage column 19 is in frictional contact with the outer peripheral surface of the friction wheel 25. A friction plate 38 is provided on each of the two sides of the intermediate column 32. One friction plate 38 is connected to the friction wheel 23, and the other friction plate 38 is connected to the friction wheel 25.
[0050] The intermediate column 32 can synchronously drive the three friction wheels 23 to rotate. The inner side of the limiting cylinder 24 is smooth, and the limiting cylinder 24 and the intermediate column 32 are in clearance fit. The inner side of the sealing cover 15 is rotatably connected to the central column 20. One end of the central column 20 is inserted and fixed to the inner side of the friction wheel 23. The central column 20 is fixed to one end of the shielding cover 22. One side of the intermediate column 32 is frictionally connected to the outer side of the friction wheel 25, and the outer side of the friction wheel 23 is frictionally connected to the other side of the intermediate column 32. The end of the shielding cover 22 away from the central column 20 has a reserved ventilation channel. 21. There are multiple central pillars 20 and shielding covers 22. The shielding cover 22 extends into the large square hole and divides the large square hole into several small square holes. The outer side of the shielding cover 22 away from the closing cover 15 is curved. The venting channel 21 allows the small openings to still communicate with the outside when they are closed by the shielding cover 22. A sieve is installed on the inner side of the venting channel 21. The shielding cover 22 is placed at an angle. The angled placement of the shielding cover 22 can reduce the amount of liquid entering the inner side of the closing cover 15. A large sieve 29 is provided on the side of the closing cover 15 away from the large square hole. The large sieve 29 connects the inner side of the closing cover 15 with the inner side of the housing 12.
[0051] The elastic element 28 is a tower spring, and the medium liquid and solvent are both distilled water. The motor 11 controls the blade 33 to rotate to generate airflow, which can be supplied into the receiving cavity 6 through the outer channel 36, connecting pipe 37 and communication hole 3, or the air inside the receiving cavity 6 can be extracted.
[0052] The motor 17 controls the blade 18 to rotate and generate airflow, which then flows from the receiving cavity 6 through the inside of the closed cover 15 and the square hole to the outside.
[0053] The specific implementation method is as follows: When the liquid is spilled onto the casing 12, some of the liquid accumulates on the inside of the liquid bottle 14 under the action of gravity. Under the action of gravity, the liquid bottle 14 is squeezed and pushed to move the linkage column 19 and the elastic element 28. During the movement, the linkage column 19 drives several friction wheels 25 to rotate synchronously through friction. The friction wheels 25 drive the middle column 32 to move through friction. The middle column 32 drives the friction wheel 23 to rotate. The friction wheel 23 drives the central column 20 to rotate. The central column 20 controls the shielding cover 22 to change its angle with the horizontal plane.
[0054] After rainfall occurs, the rainfall itself will cool and lower the temperature of the casing 12, thereby reducing the airflow size, causing the shielding cover 22 to reduce the size of the channel connecting the square hole to the outside, thereby further reducing the entry of liquid into the 60 inner side.
[0055] On the other hand, the VC heat sink 7 and the heat dissipation block 8 will continuously supply heat energy to the liquid bottle 14, causing the liquid in the liquid bottle 14 to evaporate continuously. After the liquid in the liquid bottle 14 decreases, the linkage column 19 will move under the pressure of the elastic element 28, and then through a series of transmissions, the shielding cover 22 will swing, increasing the size of the square hole and the channel for communication with the outside world, and increasing the airflow.
[0056] Furthermore, during the movement of the linkage column 19, the linkage column 19 moves the slider 39 through the crossbeam 31 and the linkage frame 30. The slider 39 moves the slider 40, changing the contact position between the slider 40 and the variable resistor 41, thus changing the effective resistance value of the variable resistor 41 connected to the circuit, thereby changing the current input to the motor 17 and changing the working power of the motor 17. This controls the airflow generated by the rotation of the blade 18, which changes in conjunction with the swing of the shielding cover 22 and the change in the size of the square hole channel. When the size of the square hole channel decreases, the motor 17 controls the airflow generated by the rotation of the blade 18 to decrease.
[0057] The slider 40, the variable resistor 41, the motor 17, and the power supply form a circuit.
[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
