Description

Technical Field

[0001] The present invention relates to the technical field of switch cabinets, and in particular to a temperature-controlled intelligent switch cabinet. Background Art

[0002] Smart switchgear is a combination of electrical equipment used for energy distribution, control, protection, and monitoring in power systems. Typically housed in a metal cabinet, it is widely used in power plants, substations, industrial power systems, and building distribution systems. Its basic functions include energy distribution, circuit control, fault protection, monitoring, and metering. Its main components include circuit breakers, disconnectors, protective relays, busbars, meters and indicators, and the cabinet itself. The cabinet provides support, protection, and heat dissipation.

[0003] During the use of smart switch cabinets, we found that the temperature control function of smart switch cabinets in extreme environments is not ideal. For example, in the Gobi environment, the best solution for the heat dissipation effect of smart switch cabinets is to use the underground low-temperature soil and rocks for heat dissipation. However, this method still has problems. The water used for heat exchange circulates, and after the water exchanges heat with the cabinet body, it enters the underground pipes, thereby using the low temperature underground to cool the water after heat exchange. However, due to the connection of the pipes, the water after heat exchange will also exchange heat with the water that has been cooled by the soil and rocks. As a result, the water that has been cooled by the underground soil and rocks cannot be restored to its initial low temperature, affecting the heat dissipation effect of the cabinet. Summary of the Invention

[0004] In order to overcome the shortcomings mentioned in the above background technology, the present invention provides a temperature-controlled intelligent switch cabinet.

[0005] The technical solution is: a temperature-controlled intelligent switch cabinet, including a cabinet body, the cabinet body is provided with three pipe networks, a water storage tank is provided under the cabinet body, a partition plate is sealed and slidably connected in the water tank, the partition plate is made of heat-insulating material, the water tank is fixedly connected to a mounting frame, the mounting frame is fixedly connected to a shell and a motor, the output shaft of the motor passes through the shell and is rotatably connected to it, the output shaft of the motor is fixedly connected to a rotating frame, the rotating frame is rotatably connected to a number of rollers, the water tank is connected to a first pipe and a second pipe, the three pipe networks are all connected to the first pipe and the second pipe, the first pipe and the second pipe are squeezed by the shell and the adjacent rollers, and the pipe network, the water tank, the first pipe and the second pipe are all filled with water.

[0006] As a further preferred solution, the cabinet body is fixed with three insulation shells, and the insulation shells are slidably and rotatably connected to two insulation plates. One insulation shell and two insulation plates together cover the adjacent pipe networks.

[0007] As a further preferred solution, the two insulation plates on the same insulation shell are connected to a rod rack in a common rotation, the cabinet body is fixed with an electric push rod, the telescopic end of the electric push rod is fixed with a sliding rack, the sliding rack is fixed with the middle rod rack, the sliding rack is slidably connected with the rod racks on both sides, and the cabinet body is provided with a temperature sensor.

[0008] As a further preferred solution, the cabinet body is fixed with a fixed rod, the fixed rod is rotatably connected to a rotating shell, the rotating shell is fixed with blades and several hemispherical shells, the cabinet body is fixed with three ventilation shells, and the ventilation shells are connected to the adjacent insulation shells.

[0009] As a further preferred solution, the cabinet body is fixed with six sliding rails, and the two sliding rails on the same side slide together and are rotatably connected to an adjusting door. The cabinet body is fixed with three windshield shells, which are used to block the gap between two adjacent sliding rails on different sides.

[0010] As a further preferred solution, the cabinet body is rotatably connected to an adjustment ring, the adjustment ring is fixedly connected to a wind direction plate, and the three adjustment doors are all pressed against the adjustment ring.

[0011] As a further preferred solution, the ventilation shell is slidably connected to a gate, and the gate is fixedly connected to the adjacent rod frame.

[0014] As a further preferred solution, the angle between the tangent of the slide rail and the horizontal plane gradually decreases from bottom to top.

[0015] Compared with the existing technology, the present invention has the following advantages: the present invention absorbs the heat of the cabinet through water entering the pipe network, and then enters one side of the water storage tank, so that the underground soil and rocks quickly cool down the water after heat exchange, and the other side is the water before heat exchange, so that the partition plate separates the two parts of water with different temperatures, reducing the heat exchange between the two parts of water, so that the water before heat exchange is kept at the initial low temperature, and ensuring the efficiency of water heat exchange with the cabinet.

[0016] The pipe network is covered with an insulation shell and insulation board to reduce the heat exchange between the water and air in the pipe network and the temperature loss of the water in the pipe network. When the ambient temperature is conducive to the heat dissipation of the cabinet, the electric push rod drives the insulation board to open, and the ambient temperature is used to assist in the heat dissipation of the cabinet, thereby reducing energy consumption.

[0017] When there is wind, the wind blows the hemispherical shell to rotate, and the hemispherical shell drives the blades to rotate, converting the horizontal wind flow into a downward wind flow blowing toward the cabinet, thereby improving the utilization rate of the wind flow. At the same time, the adjustment door facing away from the wind flow is fully opened, so that more wind flow blows toward the side of the cabinet facing away from the wind flow, making the heat dissipation effect on the cabinet more uniform.

DETAILED DESCRIPTION

[0025] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] This embodiment discloses a temperature-controlled intelligent switch cabinet for use in harsh Gobi environments.

[0028] Please refer to Figure 1-Figure 3, including a cabinet 1, which is equipped with a circuit breaker, an isolating switch, a protective relay, a busbar (busbar), and instruments and indicator lights. The cabinet 1 is provided with three pipe networks 2, which are respectively located on the left and right sides and the rear side of the cabinet 1. A water tank 3 is provided under the cabinet 1. The water tank 3 is buried in the sand and uses the low temperature underground to cool the water in the water tank 3. Fins are provided on the outside of the water tank 3 to increase the contact area between the water tank 3 and the soil and stone, thereby improving the heat exchange efficiency. A partition plate 4 is sealed and slidably connected inside the water tank 3. The partition plate 4 divides the water tank 3 into two parts, one part contains low-temperature water before heat exchange, and the other part contains high-temperature water after heat exchange. The partition plate 4 uses insulating material to further reduce the heat exchange between low-temperature water and high-temperature water. A mounting frame 5 is fixed to the upper side of the water tank 3, and the mounting frame 5 is fixed to a shell 6 and a motor 7. The shell 6 consists of two arc plates and a straight plate. The arc length of the two arc plates is greater than one-third of the circle they are located in. The output shaft of the motor 7 passes through the shell 6 and is rotatably connected to it. The output shaft of the motor 7 is fixedly connected to the rotating frame 8. The rotating frame 8 is rotatably connected to a number of rollers 9. There are at least three rollers 9, and they are evenly distributed circumferentially, so that each of the two arc-shaped plates always has a roller 9 to squeeze the first pipe 10 and the second pipe 11 with it. The water storage tank 3 is connected to the first pipe 10 and the second pipe 11. The connection points of the first pipe 10 and the second pipe 11 with the water storage tank 3 are respectively located on both sides of the partition plate 4. The three pipe networks 2 are all connected to the first pipe 10 and the second pipe 11. The first pipe 10 and the second pipe 11 are squeezed by the shell 6 and the adjacent rollers 9. The first pipe 10 and the second pipe 11 are made of pressure-resistant and soft materials, such as silicone. By continuously squeezing the first pipe 10 and the second pipe 11, the water in them is driven. Its principle is the same as that of the peristaltic pump. The pipe network 2, the water storage tank 3, the first pipe 10 and the second pipe 11 are all filled with water.

[0029] The working process of the temperature-controlled intelligent switch cabinet in this embodiment is as follows:

[0030] When using this device, first bury the water tank 3 in the sand. If the mounting frame 5, shell 6, motor 7, rotating frame 8 and roller 9 are buried in the sand with the water tank 3, isolation measures must be taken to prevent soil and rocks from intruding. You can also choose to set the mounting frame 5 on the ground, and then install the cabinet 1 on the ground. When this device is working, the motor 7 is started, and the output shaft of the motor 7 drives the rotating frame 8 to rotate clockwise in the direction of the front view. The rotating frame 8 drives the three rollers 9 to rotate. The roller 9 on the right squeezes the part of the second pipe 11 located in the shell 6 from top to bottom, and the roller 9 on the left squeezes the first pipe 11 from bottom to top. The pipe 10 is located in the part of the shell 6, so that the water in the second pipe 11 enters the right side of the water tank 3, and the water on the left side of the water tank 3 enters the first pipe 10, and then enters the three pipe networks 2 from the first pipe 10. At this time, the heat of the cabinet 1 is transferred to the three pipe networks 2, and the three pipe networks 2 transfer the heat generated in the cabinet 1 to the water. The water then returns to the water tank 3 through the second pipe 11, and then the water exchanges heat with the underground soil and rock in the water tank 3. In the above process, the partition plate 4 moves from right to left. When the partition plate 4 moves to the leftmost side, the motor 7 rotates counterclockwise, and the above process is repeated.

[0031] Example 2

[0032] The temperature-controlled intelligent switch cabinet disclosed in this embodiment, based on the first embodiment, further has the function of reducing the heat loss of water.

[0033] Please refer to Figure 1 and Figure 3 The cabinet body 1 is fixed with three insulation shells 12, which are respectively located on the left and right sides and the rear side of the cabinet body 1. The insulation shells 12 are slidably and rotatably connected to two insulation plates 13. One insulation shell 12 and two insulation plates 13 together cover the adjacent pipe network 2, thereby reducing the heat exchange between the pipe network 2 and the air. The area of ​​the cabinet body 1 not covered by the insulation shell 12 and the insulation plate 13 is coated with an insulation coating, thereby reducing the impact of the ambient temperature on the cabinet body 1.

[0034] Please refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 6 The two insulation boards 13 on the same insulation shell 12 rotate together and are connected to a rod frame 14. When the rod frame 14 moves, it drives the two adjacent insulation boards 13 to move, thereby switching the insulation boards 13 between open and closed. An electric push rod 15 is fixed to the upper side of the cabinet 1, and the telescopic end of the electric push rod 15 is fixed to a sliding frame 16. The sliding frame 16 is fixed to the rod frame 14 on the rear side, and the sliding frame 16 is slidably connected to the rod frames 14 on the left and right sides. A temperature sensor is provided on the outside of the cabinet 1, and the temperature sensor is used to monitor the ambient temperature.

[0035] The working process of this embodiment is similar to that of the first embodiment and is described in detail as follows:

[0036] When the ambient temperature affects the heat dissipation of the cabinet 1, the insulation board 13 is in a closed state, isolating the pipe network 2 from the outside world, reducing the temperature loss of the water in the pipe network 2 during heat exchange; when the ambient temperature is conducive to the heat dissipation of the cabinet 1, the electric push rod 15 starts and extends, and the telescopic end of the electric push rod 15 drives the sliding frame 16 to move backward, and the sliding frame 16 drives the rear rod frame 14 to move backward and squeezes the rod frames 14 on both sides to move back to back, and the rod frames 14 drive the two adjacent insulation boards 13 to move, so that the insulation boards 13 release the cover of the pipe network 2, so that the cabinet 1 can exchange heat with the air. At the same time, when the ambient temperature is low enough, the motor 7 can be turned off, and heat dissipation can be achieved only by the ambient temperature.

[0037] Example 3

[0038] This embodiment discloses a temperature-controlled intelligent switch cabinet, which is further improved on the basis of the second embodiment.

[0039] Please refer to Figure 1 、 Figure 4 and Figure 5 A fixed rod 17 is fixed to the middle part of the upper side of the cabinet body 1, and the upper part of the fixed rod 17 is rotatably connected to a rotating shell 18. The rotating shell 18 is fixed with a blade fan 19 and several hemispherical shells 20. The blade fan 19 is located on the lower side of the rotating shell 18, and the hemispherical shell 20 is located on the upper side of the rotating shell 18. Three ventilation shells 21 are fixed to the cabinet body 1. The ventilation shell 21 is used to guide the airflow generated by the rotation of the blade fan 19 into the insulation shell 12. The ventilation shell 21 is connected to the adjacent insulation shell 12.

[0040] The workflow of this embodiment is:

[0041] When the ambient temperature is conducive to the heat dissipation of the cabinet 1 and there is wind, the wind blows toward the part of the cabinet 1 that is not coated with the thermal insulation coating, taking away the heat of the cabinet 1. At the same time, the wind blows the hemispherical shell 20 to rotate, and the hemispherical shell 20 drives the rotating shell 18 to rotate, and the rotating shell 18 drives the blade fan 19 to rotate. The rotation of the blade fan 19 generates downward wind, so that the wind flows through the ventilation shell 21 to the part of the cabinet 1 that is not coated with the thermal insulation coating, thereby increasing the wind flow in this part and improving the heat dissipation effect.

[0042] Example 4

[0043] This embodiment discloses a temperature-controlled intelligent switch cabinet. Based on the third embodiment, the airflow generated by the blade fan 19 is distributed to achieve a more uniform heat dissipation effect.

[0044] Please refer to Figure 4 and Figure 5The cabinet body 1 is fixed with six slide rails 22, two slide rails 22 form a group, and there is a group on each of the left and right rear parts of the upper side of the cabinet body 1. The two slide rails 22 on the same side slide together and are rotatably connected to an adjustment door 23. The adjustment door 23 consists of two round rods and a rectangular plate, wherein the round rod on the upper side is longer than the round rod on the lower side. The cabinet body 1 is fixed with three windshield shells 24, which are used to block the gap between two adjacent slide rails 22 on different sides.

[0045] Please refer to Figure 4 and Figure 5 The upper side of the cabinet 1 is rotatably connected with an adjusting ring 25, the lower side of the adjusting ring 25 is horizontal, and the upper side of the adjusting ring 25 is inclined. In the figure, the contact point between the adjusting ring 25 and the left adjusting door 23 is the highest, and the contact point between the adjusting ring 25 and the right adjusting door 23 is the lowest. The middle part changes evenly. The left side of the adjusting ring 25 is fixed with a wind deflector 26, and the three adjusting doors 23 are squeezed against the adjusting ring 25.

[0046] The workflow of this embodiment is:

[0047] Here, the wind flow from right to left is taken as an example. When the wind deflector 26 is not initially in the state shown in the figure, the wind flow blows the wind deflector 26, and the wind deflector 26 drives the adjustment ring 25 to rotate. The adjustment ring 25 changes the height of the three adjustment doors 23. When the wind deflector 26 is rotated to the position shown in the figure, the height of the three adjustment doors 23 gradually decreases from left to right, that is, the amount of air that can enter the ventilation shell 21 gradually decreases from left to right. Because the left side of the cabinet 1 is facing away from the wind flow, most of the wind flow generated by the blade fan 19 is blown to the left side of the cabinet 1 through the ventilation shell 21 on the left, and a small part is blown to the back side of the cabinet 1, and the adjustment door 23 on the right completely blocks the ventilation shell 21 on the right, so that the heat dissipation effect of each part of the cabinet 1 is better and more uniform. At this time, the insulation board 13 is in Figure 6 In the state shown, under the action of the two insulation plates 13 on the left, the wind flow blown downward from the left ventilation shell 21 will not disperse directly, but will continue to flow a longer distance from top to bottom along the air duct formed by the two insulation plates 13, thereby improving the utilization rate of the wind flow and further improving the heat dissipation effect.

[0048] Example 5

[0049] The temperature-controlled intelligent switch cabinet disclosed in this embodiment, based on the third embodiment, further has the function of sealing the ventilation shell 21 .

[0050] Please refer to Figure 4 The ventilation shell 21 is slidably connected to a gate 27 , which is used to control the communication state of adjacent ventilation shells 21 , and the gate 27 is fixedly connected to the adjacent rod frame 14 .

[0051] The workflow for this part:

[0052] When the insulation board 13 is closed, the gate 27 is also in a closed state to reduce the gap between the insulation shell 12 and the insulation board 13 to form a cavity, thereby reducing the heat exchange between the pipe network 2 and the outside air. When the insulation board 13 is opened, the rod frame 14 will drive the adjacent gate 27 to move, so that the gate 27 releases the blockage of the ventilation shell 21 to allow airflow to pass through.

[0053] Example 6

[0054] This embodiment discloses a temperature-controlled intelligent switch cabinet, which further improves the slide rail 22 based on the fourth embodiment.

[0055] Please refer to Figure 4 and Figure 5 , the angle between the tangent line of the slide rail 22 and the horizontal plane gradually decreases from bottom to top.

[0056] The above arrangement can achieve the following: the higher the position of the adjustment door 23 is, the greater the inclination is, thereby producing a wind-driving effect, guiding the horizontal wind flow, increasing the wind flow entering the ventilation shell 21, and improving the heat dissipation effect.

[0057] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be covered by the scope of protection of the present invention.
