Description

Technical Field

[0001] This application relates to the field of power distribution equipment, and particularly to a high-precision deep integration ring main unit box. Background Art

[0002] A high-precision deep integration ring main unit box is a power distribution equipment integrating a variety of advanced technologies, which deeply integrates a ring main unit cabinet, high-precision sensors and secondary terminal equipment in a box body, aiming to improve the performance, reliability and intelligent level of the power distribution system.

[0003] Considering the outdoor working environment, the ring main unit box usually has good waterproof and dustproof performance, can adapt to various harsh weather conditions and environments, adopts a sealed design and a protective coating to prevent rain, dust, etc. from entering the box and affecting the normal operation of the equipment.

[0004] However, due to the equipment being in a sealed state, it is not easy to dissipate heat from the ring main unit box, and the heat dissipation efficiency of the ring main unit box is low. Electronic components work in a high-temperature working environment, which easily shortens the service life of the equipment. Summary of the Invention

[0005] In order to extend the service life of the ring main unit box, this application provides a high-precision deep integration ring main unit box.

[0006] The high-precision deep integration ring main unit box provided by this application adopts the following technical solutions:

[0007] A high-precision deep integration ring main unit box includes a box body, the box body is provided with a receiving cavity and a heat dissipation flow channel, the heat dissipation flow channel is arranged on the outer periphery of the receiving cavity, the outer wall of the box body is provided with an air inlet, a water inlet and a discharge port, both ends of the heat dissipation flow channel are respectively communicated with the air inlet and the discharge port, and the water inlet is communicated with the heat dissipation flow channel.

[0008] By adopting the above technical solutions, air enters the heat dissipation flow channel from the air inlet and is discharged from the discharge port, air-cooling the box body, and water enters the heat dissipation flow channel from the water inlet and is discharged from the discharge port, water-cooling the box body, which is convenient for dissipating heat from the ring main unit box and extending the service life of the ring main unit box.

[0009] Preferably, the heat dissipation flow channel includes branch channels, communication ports and a converging flow channel. There are two branch channels, and there are two air inlets. The two air inlets are respectively arranged at both ends of the box body. The branch channels are arranged in one-to-one correspondence with the air inlets. One end of the branch channel is communicated with the air inlet, the other end of the branch channel is communicated with the communication port, one end of the converging flow channel is communicated with the communication port, the other end of the converging flow channel is communicated with the discharge port, and the water inlet is communicated with the branch channel.

[0010] By adopting the above technical solution, since the wind direction is liable to change, the air inlets facing opposite directions facilitate the entry of wind from all directions into the heat dissipation channel, thus facilitating better utilization of wind for dissipating heat from the box body.

[0011] Preferably, it further includes a filter screen which is fixedly connected to the outer wall of the box body and covers the air inlet.

[0012] By adopting the above technical solution, the filter screen reduces the entry of external impurities into the heat dissipation channel and reduces the probability of blockage of the heat dissipation channel.

[0013] Preferably, it further includes a baffle. The height of the branch channel increases as it is farther away from the communication port. The baffle is arranged between two branch channels. One end of the baffle is fixedly connected with a hinge column which is hinged to the inner wall facing downwards of the communication port. The baffle is used to cover the branch channel.

[0014] By adopting the above technical solution, when the wind enters from one branch channel through the air inlet, the wind pushes the baffle to cover the other branch channel, reducing the probability that the wind enters from one air inlet and exits from the other air inlet, enabling the wind to pass through the converging channel, improving the heat dissipation efficiency and prolonging the service life of the ring network box.

[0015] Preferably, the baffle is provided with a ventilation port which is used to communicate with the branch channel.

[0016] By adopting the above technical solution, when the wind enters from one branch channel through the air inlet, the wind pushes the baffle to cover the other branch channel. Part of the wind passes through the converging channel and the other part passes through the ventilation port to clean the filter screen, reducing the probability of blockage of the filter screen.

[0017] Preferably, a water storage tank is arranged at the upper end of the box body. The bottom of the water storage tank is communicated with the water inlet which is arranged above the branch channel. There are two water inlets which are arranged in one-to-one correspondence with the branch channels.

[0018] By adopting the above technical solution, the water storage tank is convenient for storing water. The water enters the communication port through the branch channel. Both side branch channels are supplied with water, making the baffle under balanced force and the water flow smoothly, facilitating water-cooling heat dissipation.

[0019] Preferably, it further includes a first metal sheet, a floating plate and a magnetic sheet. An indicating port is arranged on the outer wall of the box body. The indicating port is arranged between two branch channels and above the communication port. The indicating port is communicated with the communication port. The hinge column is slidably connected to the inner wall of the indicating port. The sliding direction of the hinge column is vertical. One end of the hinge shaft extends out of the box body. The first metal sheet is fixedly connected to the inner wall facing downwards of the indicating port. The floating plate is fixedly connected to the lower end of the baffle. The magnetic sheet is fixedly connected to the upper end of the floating plate. The floating plate is used to cover the indicating port.

[0020] By adopting the above technical solution, the water storage rate in the communication port is greater than the drainage rate of the converging flow channel. The rising water level causes the floating plate to slide upward. When the distance between the magnetic piece and the first metal piece shortens, the two attract each other, causing the floating plate to cover the indicating port, reducing the probability of water leakage from the indicating port. When the position of the hinge column is relatively high, the box body is for water-cooled heat dissipation. When the position of the hinge column is relatively low, the box body is for air-cooled heat dissipation.

[0021] Preferably, it further includes a pointer, and the pointer is arranged on the outer periphery of the box body, and the pointer is fixedly connected to the outer wall of the hinge column.

[0022] By adopting the above technical solution, the pointer moves along with the hinge column, and the pointer indicates the state of the hinge column, which is convenient for the user to judge the state of the baffle.

[0023] Preferably, it further includes a cover plate, a sealing ring and a first shape memory alloy. One side of the cover plate is provided with a sealing groove, one side of the sealing ring is fixedly embedded in the sealing groove, the other side of the sealing ring abuts against the bottom of the water storage tank, the cover plate is used to cover the water inlet, the sealing ring is arranged on the outer periphery of the water inlet, the bottom of the water storage tank is provided with a mounting groove, the mounting groove is arranged between the sealing ring and the water inlet, one end of the first shape memory alloy is fixedly connected to the bottom of the mounting groove, and the other end of the first shape memory alloy is fixedly connected to the cover plate.

[0024] By adopting the above technical solution, when the temperature of the box body is relatively high, the first shape memory alloy deforms and elongates, causing the cover plate to move away from the water inlet. The water in the water storage tank enters the branch channel through the water inlet. When the temperature of the box body is relatively high and the air-cooled heat dissipation cannot meet the heat dissipation requirement, the box body is cooled by water-cooled heat dissipation, improving the heat dissipation efficiency and prolonging the service life of the ring network box.

[0025] Preferably, it further includes a sliding plate, a partition plate, a connecting rod, a spring and a second shape memory alloy. The bottom of the water storage tank is provided with a limiting groove, the limiting groove is arranged between the sealing ring and the water inlet, the sliding plate is slidably connected to the inner wall of the limiting groove, the inner wall of the downward-facing branch channel is provided with a placing groove, the placing groove is arranged on the side of the water inlet away from the communication port, the placing groove communicates with the limiting groove, the partition plate is slidably connected to the inner wall of the placing groove, the partition plate is used to partition the branch channel, one end of the connecting rod is fixedly connected to the sliding plate, the other end of the connecting rod is fixedly connected to the partition plate, the spring is sleeved on the outer periphery of the connecting rod, one end of the spring abuts against the sliding plate, the other end of the spring abuts against the bottom of the limiting groove, one end of the second shape memory alloy is fixedly connected to the cover plate, and the other end of the second shape memory alloy abuts against the sliding plate.

[0026] By adopting the above technical solution, when the ambient temperature is too low, the second shape memory alloy deforms and elongates. Since the first shape memory alloy tightens the cover plate, the second shape memory alloy pushes the sliding plate to slide downward, causing the partition plate to slide downward to block the branch channel, facilitating heat preservation of the box body, enabling the ring network box to work at an appropriate temperature, and extending the service life of the ring network box.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] The wind enters the heat dissipation channel from the air inlet and is discharged from the discharge port, air-cooling the box body. Water enters the heat dissipation channel from the water inlet and is discharged from the discharge port, water-cooling the box body, facilitating heat dissipation of the ring network box, and extending the service life of the ring network box;

[0029] The rate of water storage in the communication port is greater than the rate of water drainage in the collecting channel. The rising water level causes the floating plate to slide upward. When the distance between the magnetic piece and the first metal piece is shortened, the two attract each other, causing the floating plate to cover the indicating port, reducing the probability of water leakage from the indicating port. When the position of the hinge column is higher, the box body is water-cooled. When the position of the hinge column is lower, the box body is air-cooled;

[0030] When the ambient temperature is too low, the second shape memory alloy deforms and elongates. Since the first shape memory alloy tightens the cover plate, the second shape memory alloy pushes the sliding plate to slide downward, causing the partition plate to slide downward to block the branch channel, facilitating heat preservation of the box body, enabling the ring network box to work at an appropriate temperature, and extending the service life of the ring network box.

[0048] The implementation principle of a high-precision deep fusion ring network box in an embodiment of the present application is as follows: When there is wind in the external environment, the wind enters the branch channel 121 from the air inlet 14 and drives the baffle 51 to rotate. The second metal sheet 58 adsorbs the magnetic sheet 56, so that the baffle 51 covers another branch channel 121. Most of the gas passes through the converging channel 123, and a small part of the gas is discharged from the other branch channel 121 to clean the filter net 4. When there is no wind in the external environment, the gravity of the baffle 51 overcomes the suction force between the second metal sheet 58 and the magnetic sheet 56, and the baffle 51 returns to the vertical state. The pointer 53 indicates the state of the baffle 51. The water storage tank 16 is used to store water. When the temperature of the box body 1 is too high, the first shape memory alloy 63 deforms and elongates to push the cover plate 61 to move upward, the water inlet 17 is opened, and the water flows from the branch channel 121 into the communication port 122 and then is discharged from the converging channel 123. The speed of entering the communication port 122 is less than the speed of discharging from the branch channel 121, so that the baffle 51 slides upward, the first metal sheet 57 adsorbs the magnetic sheet 56, and the floating plate 55 covers the indicating port 18 to remind the operator that water cooling is in progress. When the water is used up and the temperature is still too high, the water inlet 17 facilitates the upward discharge of hot air. When the temperature of the box body 1 is too low, the first shape memory alloy 63 tightens the cover plate 61, and the second shape memory alloy 68 deforms and elongates to push the partition plate 65 to slide to block the branch channel 121, reducing the entry of low-temperature water and low-temperature air into the branch channel 121, keeping the ring network box at an appropriate temperature, reducing the occurrence of icing phenomena, and extending the service life of the ring network box.

[0049] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
