Description

Technical Field

[0001] This invention relates to the field of intelligent power distribution cabinet technology, and more specifically to a temperature-controlled intelligent power distribution cabinet. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, metering cabinets, and intelligent distribution cabinets. They are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. They are used in situations where the load is relatively dispersed and there are few circuits. Intelligent distribution cabinets are precision distribution cabinets, which are designed for the energy end of data center computer rooms and comprehensively collect all energy data. As a commonly used power distribution device in power transmission equipment, distribution cabinets play a crucial role.

[0003] Currently, during the use of power distribution cabinets, the internal electrical components generate heat, causing the internal temperature of the cabinet to rise. To ensure the safe use of power distribution cabinets, cooling fans or metal heat sinks are often installed to cool down the internal temperature.

[0004] However, cooling fans tend to accumulate dust during long-term operation, reducing their heat dissipation efficiency and requiring regular maintenance. On the other hand, using heat sinks for heat dissipation is not very effective in high-temperature or enclosed environments and is difficult to cope with sudden load increases in temperature, which is extremely inconvenient. In addition, existing power distribution cabinets cannot intelligently adjust the start and stop of exhaust fans according to the internal temperature, resulting in additional power loss and energy waste. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a temperature-controlled intelligent power distribution cabinet to solve the problems existing in the background art.

[0006] This invention provides the following technical solution: a temperature-controlled intelligent power distribution cabinet, comprising a cabinet body, a main exhaust pipe fixedly sleeved at the top of the cabinet body, auxiliary exhaust pipes fixedly sleeved on both sides of the cabinet body where the main exhaust pipe is fixedly sleeved, a fixed base fixedly connected to the bottom of the cabinet body, self-cleaning air inlet pipes arranged in a regular pattern having opened on both sides of the fixed base, a cabinet cavity having opened inside the cabinet body, an air inlet hole having opened at the bottom of the cabinet cavity, and columns having opened at the positions where the main exhaust pipe and auxiliary exhaust pipes are fixedly sleeved on the cabinet body. The cabinet has a cylindrical groove, with a wiring box fixedly connected to the top. A protective cover is fixedly connected to one end of the wiring box and to the top of the main exhaust duct. Exhaust fans are fixedly connected to the bottom of the cylindrical groove. Through the main exhaust duct, auxiliary exhaust duct, and self-cleaning air inlet duct, the cabinet can dissipate heat by drawing away hot air from the inside of the cabinet through the main exhaust duct and auxiliary exhaust duct, creating a negative pressure inside the cabinet and drawing in cool air from the outside through the self-cleaning air inlet duct, thus quickly achieving the heat dissipation effect inside the cabinet.

[0007] Furthermore, a temperature control circuit assembly is fixedly connected to the top of the main exhaust duct, and a temperature sensing assembly is fixedly connected to the top of the inside of the main exhaust duct. Connecting pipes are fixedly connected to both sides of the main exhaust duct near the top, and the other end of each connecting pipe is fixedly connected to the inside of an auxiliary exhaust duct. An auxiliary pressurized exhaust cone is fixedly connected to the inside of each auxiliary exhaust duct, and an exhaust hood is fixedly connected to the top of each auxiliary exhaust duct. Through the temperature sensing assembly and the temperature control circuit assembly, the movable sealing plug can rise and fall according to temperature changes inside the cabinet. This allows the rectangular conductive plates at the top of the first and second telescopic rods to connect or disconnect from the temperature control circuit assembly, enabling the exhaust fan to automatically start and stop in real time according to temperature changes, thus avoiding energy waste.

[0008] Furthermore, the temperature control circuit assembly includes a main circuit connector, and auxiliary circuit connectors are fixedly connected to the top of the main exhaust pipe on both sides of the main circuit connector. A connecting groove is opened on the surface of the adjacent side of the main circuit connector, and a rectangular groove is opened on the bottom of the adjacent side of the auxiliary circuit connector. Through the main circuit connector and the auxiliary circuit connector, when the temperature inside the cabinet changes, the temperature sensing component raises and lowers to close the connection between the main circuit connector and the auxiliary circuit connector, thereby completing the start and stop of the exhaust fan and thus changing the heat dissipation and temperature control effect.

[0009] Furthermore, the temperature sensing component includes a sealed box with an air storage cavity inside. A temperature-conducting cone is fixedly connected to the bottom of the sealed box, and a temperature-conducting plate is fixedly connected to the bottom of the temperature-conducting cone inside the sealed box. A movable sealing plug is movably fitted onto the top of the sealed box. Fixed brackets are provided on both sides of the top of the sealed box, and the ends of the fixed brackets away from the sealed box are fixedly connected to the top of the main exhaust duct. A first telescopic rod is fixedly connected to the top of the movable sealing plug, and second telescopic rods are fixedly connected to both sides of the top of the first telescopic rod. A rectangular conductive sheet is fixedly connected to the top of both the second and first telescopic rods. The first and second telescopic rods are movably fitted onto the top of the main exhaust duct. Through the movable sealing plug, the first and second telescopic rods, and the rectangular conductive sheets, the volume of air inside the air storage cavity can be changed by temperature changes. This allows the movable sealing plug to move the first and second telescopic rods up and down, enabling the rectangular conductive sheets to connect and disconnect the temperature control circuit component.

[0010] Furthermore, an exhaust chamber is provided inside the exhaust hood, an exhaust pressure chamber is provided at the top of the exhaust chamber, an exhaust port is provided on one side of the surface of the exhaust chamber, and buzzer holes are provided around the surface of the exhaust pressure chamber. The exhaust hood and buzzer holes help to protect the auxiliary exhaust nozzles from external dust by the exhaust hood, and accelerate the exhaust of hot air inside the cabinet by the buzzer holes while issuing a high temperature warning to avoid safety risks.

[0011] Furthermore, each of the auxiliary exhaust pipes has a connection port on the side near the main exhaust pipe, and each of the auxiliary exhaust pipes has an auxiliary exhaust nozzle movably fitted onto its top. Each of the auxiliary pressurized exhaust cones is movably fitted inside the auxiliary exhaust nozzle, with its top end located inside the buzzer hole. The auxiliary exhaust nozzle helps to separate the gas discharged from the main exhaust pipe from the auxiliary exhaust pipe, preventing the buzzer hole from emitting a buzzer during normal exhaust.

[0012] Furthermore, the auxiliary pressurized exhaust cone has a pressurized inner cavity, and the auxiliary exhaust nozzle has a limiting plate near the bottom. The auxiliary exhaust nozzle has exhaust holes near the top on all four sides. The exhaust holes are all spiral-shaped. The spiral shape of the exhaust holes helps to rotate the auxiliary exhaust nozzle during normal heat dissipation and exhaust, thereby accelerating the exhaust of hot air by the centrifugal force generated by the rotation of the auxiliary exhaust nozzle, thus improving the heat dissipation effect.

[0013] Furthermore, a filter screen is fixedly connected to the inside of the self-cleaning air intake pipe on the side away from the fixed base, and a non-powered cleaning fan is fixedly connected to the inside of the self-cleaning air intake pipe near the filter screen. The non-powered cleaning fan helps to rotate when external cold air enters the self-cleaning air intake pipe, thereby further increasing the speed of external air entering and accelerating the heat dissipation effect inside the cabinet.

[0014] Furthermore, a cleaning rod is fixedly connected to the center of the non-powered cleaning fan near the filter screen. The cleaning rod has regularly arranged cleaning brush heads on its surface, all of which are in close contact with the filter screen surface. The cleaning rod and cleaning brush heads facilitate the rotation of the cleaning rod when the non-powered cleaning fan is rotated by the airflow, thereby allowing the cleaning brush heads on the cleaning rod surface to clean the dust attached to the filter screen surface. This prevents dust from clogging the filter screen and affecting the normal heat dissipation efficiency, while also reducing the frequency of manual maintenance and lowering the labor intensity of manual workers.

[0015] The technical effects and advantages of this invention are as follows:

[0016] 1. By incorporating a temperature sensing component and a temperature control circuit component, this invention facilitates the movement of the movable sealing plug according to temperature changes inside the cabinet. This allows the rectangular conductive plates at the top of the first and second telescopic rods to connect or disconnect from the temperature control circuit component, thereby enabling the exhaust fan to automatically start and stop in real time according to temperature changes, thus avoiding energy waste.

[0017] 2. By incorporating an auxiliary pressurized exhaust cone and an exhaust hood, this invention facilitates the pressurization of the exhaust hot air inside the auxiliary pressurized exhaust cone when the exhaust fan at the bottom of the auxiliary exhaust pipe is powered on, and then discharges it through the buzzer hole. This improves the heat dissipation efficiency inside the cabinet while simultaneously emitting a buzzer sound for early warning, thereby enhancing the safety of the power distribution cabinet during actual use.

[0018] 3. This invention features a non-powered cleaning fan, which allows the cool air drawn in by the negative pressure inside the cabinet to rotate as hot air is expelled from inside the cabinet. This, in turn, causes the cleaning rod to drive the cleaning brush head to clean the filter, thus preventing dust from clogging the filter and affecting the normal heat dissipation effect.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The temperature-controlled intelligent power distribution cabinet involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figures 1-11 As shown, the present invention provides a temperature-controlled intelligent power distribution cabinet, including a cabinet body 1. A main exhaust pipe 2 is fixedly sleeved at the top of the cabinet body 1. Auxiliary exhaust pipes 3 are fixedly sleeved at both sides of the cabinet body 1 where the main exhaust pipe 2 is fixedly sleeved. A fixed base 4 is fixedly connected at the bottom of the cabinet body 1. Self-cleaning air inlet pipes 5 are arranged in a regular pattern on both sides of the fixed base 4. A cabinet cavity 101 is opened inside the cabinet body 1. An air inlet hole 102 is opened at the bottom of the cabinet cavity 101. A cylindrical groove 103 is opened at the position where the main exhaust pipe 2 and the auxiliary exhaust pipe 3 are fixedly sleeved. A wiring box 104 is fixedly connected at the top of the cabinet body 1. A protective cover 105 is fixedly connected to one end of the wiring box 104. The protective cover 105 is fixedly connected to the top of the main exhaust pipe 2. An exhaust fan 6 is fixedly connected at the bottom of the cylindrical groove 103.

[0033] In this embodiment: the main exhaust pipe 2, the auxiliary exhaust pipe 3, and the self-cleaning air intake pipe 5 facilitate the removal of hot air from the inside of the cabinet 1 during heat dissipation. This creates a negative pressure inside the cabinet 1 and draws in cool air from the outside through the self-cleaning air intake pipe 5, thereby quickly achieving the heat dissipation effect inside the cabinet 1.

[0034] Among them, a temperature control circuit component 7 is fixedly connected to the top of the main exhaust duct 2, a temperature sensing component 8 is fixedly connected to the top of the inside of the main exhaust duct 2, a connecting pipe 11 is fixedly connected to both sides of the main exhaust duct 2 near the top, the other end of the connecting pipe 11 is fixedly connected to the inside of the auxiliary exhaust duct 3, an auxiliary pressurized exhaust cone pipe 9 is fixedly connected to the inside of the auxiliary exhaust duct 3, and an exhaust hood 10 is fixedly connected to the top of the auxiliary exhaust duct 3.

[0035] In this embodiment, the temperature sensing component 8 and the temperature control circuit component 7 facilitate the movement of the movable sealing plug 806 according to the temperature change inside the cabinet 1. This allows the rectangular conductive sheet 809 at the top of the first telescopic rod 807 and the second telescopic rod 808 to connect or disconnect from the temperature control circuit component 7, thereby enabling the exhaust fan 6 to automatically start and stop in real time according to the temperature change, thus avoiding energy loss.

[0036] Among them, the temperature control circuit assembly 7 includes a main circuit connector 701, and auxiliary circuit connectors 702 are fixedly connected to the top of the main exhaust pipe 2 on both sides of the main circuit connector 701. A connecting groove 7011 is opened on the surface of the adjacent side of the main circuit connector 701, and a rectangular groove 7021 is opened on the bottom of the adjacent side of the auxiliary circuit connector 702.

[0037] In this embodiment, the main circuit connector 701 and the auxiliary circuit connector 702 facilitate the closure between the main circuit connector 701 and the auxiliary circuit connector 702 when the temperature inside the cabinet 1 changes. This is achieved by raising and lowering the temperature sensing component 8, thereby enabling the exhaust fan 6 to start and stop, and thus changing the heat dissipation and temperature control effect.

[0038] The temperature sensing component 8 includes a sealed box 801, an air storage cavity 802 inside the sealed box 801, a temperature-conducting cone 803 fixedly connected to the bottom of the sealed box 801, a temperature-conducting plate 804 fixedly connected to the bottom of the temperature-conducting cone 803 inside the sealed box 801, a movable sealing plug 806 movably sleeved at the top of the sealed box 801, fixed brackets 805 on both sides of the top of the sealed box 801, the ends of the fixed brackets 805 away from the sealed box 801 fixedly connected to the top of the main exhaust duct 2, a first telescopic rod 807 fixedly connected to the top of the movable sealing plug 806, a second telescopic rod 808 fixedly connected to both sides of the top of the movable sealing plug 806, a rectangular conductive sheet 809 fixedly connected to the top of both the second telescopic rod 808 and the first telescopic rod 807, and both the first telescopic rod 807 and the second telescopic rod 808 movably sleeved at the top of the main exhaust duct 2.

[0039] In this embodiment: the movable sealing plug 806, the first telescopic rod 807, the second telescopic rod 808, and the rectangular conductive sheet 809 facilitate the change of the volume of air inside the air storage cavity 802 by temperature changes, thereby causing the movable sealing plug 806 to drive the first telescopic rod 807 and the second telescopic rod 808 to rise and fall, so that the rectangular conductive sheet 809 can connect and close the temperature control circuit assembly 7.

[0040] The exhaust hood 10 has an exhaust chamber 1001 inside, an exhaust pressure chamber 1003 at the top of the exhaust chamber 1001, an exhaust port 1002 on one side of the surface of the exhaust chamber 1001, and buzzer holes 1004 around the surface of the exhaust pressure chamber 1003.

[0041] In this embodiment, the exhaust hood 10 and the buzzer hole 1004 help to protect the auxiliary exhaust nozzles from external dust by the exhaust hood 10, and accelerate the exhaust of hot air inside the cabinet 1 by the buzzer hole 1004 while issuing a high temperature warning to avoid safety risks.

[0042] Among them, the auxiliary exhaust pipe 3 is provided with a connection port 301 on the side close to the main exhaust pipe 2, the top of the auxiliary exhaust pipe 3 is movably sleeved with an auxiliary exhaust nozzle 12, and the auxiliary pressurized exhaust cone pipe 9 is movably sleeved inside the auxiliary exhaust nozzle 12 with its top end located inside the buzzer hole 1004.

[0043] In this embodiment, the auxiliary exhaust nozzle 12 helps to separate the gas discharged from the main exhaust pipe 2 and the auxiliary exhaust pipe 3, thus preventing the buzzer hole 1004 from buzzing during normal exhaust.

[0044] Among them, the auxiliary pressurized exhaust cone 9 has a pressurized inner cavity 901 inside, the auxiliary exhaust nozzle 12 has a limit plate 1201 near the bottom of the surface, and the auxiliary exhaust nozzle 12 has exhaust holes 1202 near the top of the inner periphery, and the exhaust holes 1202 are all spiral-shaped.

[0045] In this embodiment, the exhaust holes 1202 are all spiral-shaped, which helps to drive the auxiliary exhaust nozzles 12 to rotate during normal heat dissipation and exhaust. This allows the centrifugal force generated by the rotation of the auxiliary exhaust nozzles 12 to further accelerate the exhaust of hot air, thereby improving the heat dissipation effect.

[0046] Among them, a filter screen 501 is fixedly connected to the inside of the self-cleaning air intake pipe 5 on the side away from the fixed base 4, and a non-powered cleaning fan 13 is fixedly connected to the inside of the self-cleaning air intake pipe 5 near the filter screen 501.

[0047] In this embodiment, the non-powered cleaning fan 13 is used to drive the non-powered cleaning fan 13 to rotate when external cold air enters the self-cleaning air intake pipe 5, thereby further increasing the speed of external air entering and accelerating the heat dissipation effect inside the cabinet 1.

[0048] Among them, a cleaning rod 1301 is fixedly connected to the middle of the side of the non-powered cleaning fan 13 near the filter screen 501. Cleaning brush heads 1302 arranged in a regular pattern are opened on the surface of the cleaning rod 1301, and the cleaning brush heads 1302 are all in contact with the surface of the filter screen 501.

[0049] In this embodiment, the cleaning rod 1301 and the cleaning brush head 1302 facilitate the rotation of the cleaning rod 1301 when the non-powered cleaning fan 13 is rotated by the airflow. This allows the cleaning brush head 1302 on the surface of the cleaning rod 1301 to clean the dust attached to the surface of the filter screen 501, thereby preventing dust blockage from affecting the normal heat dissipation efficiency. At the same time, it reduces the frequency of manual maintenance and lowers the labor intensity of manual workers.

[0050] Working principle of the invention:

[0051] First, when dissipating heat inside the cabinet 1, the wiring inside the circuit box 104 is energized, so that the rectangular conductive piece 809 inside the connecting groove 7011 of the main circuit connector 701 transmits electrical energy to the exhaust fan 6 at the bottom of the main exhaust duct 2. The exhaust fan 6 rotates and sends the hot air inside the cabinet cavity 101 into the main exhaust duct 2. Then the hot air rises around the temperature-conducting cone 803, and the temperature-conducting cone 803 transfers the temperature of the hot air to the temperature-conducting plate 804. The temperature-conducting plate 804 then heats the air inside the air storage cavity 802. The heated air inside the air storage cavity 802 expands and pushes up the movable sealing plug 806. At this time, the first telescopic rod 807 and the second telescopic rod 808 at the top of the movable sealing plug 806 rise together. At this time, the rectangular conductive piece 809 at the top of the first telescopic rod 807 slides inside the main circuit connector 701, and then the rectangular conductive piece 809 at the top of the second telescopic rod 808 moves closer to the bottom of the auxiliary circuit connector 702.

[0052] Then, the hot air around the temperature-conducting cone 803 is transported to the auxiliary exhaust pipe 3 through the connecting pipes 11 on both sides of the main exhaust pipe 2. Then, it is discharged through the exhaust hole 1202 on the surface of the auxiliary exhaust nozzle 12 at the top of the auxiliary exhaust pipe 3. Since the exhaust hole 1202 is spiral, the auxiliary exhaust nozzle 12 is rotated at the top of the auxiliary exhaust pipe 3 while the air is being discharged. The rotation of the auxiliary exhaust nozzle 12 accelerates the air inside it and improves its exhaust efficiency. Then, the hot air discharged through the exhaust hole 1202 is discharged into the outside air through the exhaust port 1002 on one side of the exhaust chamber 1001.

[0053] Then, when the hot air inside the cabinet 1 is drawn out, a negative pressure is formed inside the cabinet 1. Then, the air inlet 102 at the bottom of the cabinet cavity 101 draws in the cold air from outside through the self-cleaning air inlet pipes 5 on both sides of the fixed base 4. Then, the filter 501 blocks the dust inside the air. Then, the incoming air drives the non-powered cleaning fan 13 to rotate, which causes the non-powered cleaning fan 13 to drive the cleaning rod 1301 and the cleaning brush head 1302 to rotate and clean the dust attached to the surface of the filter 501. At the same time, the non-powered cleaning fan 13 accelerates the cold air into the fixed base 4 and sends it into the cabinet cavity 101 through the air inlet 102 to complete the heat dissipation.

[0054] Then, as the internal temperature of cabinet 1 gradually rises, the air inside the temperature-conducting plate 804 expands accordingly. When the internal temperature of cabinet 1 exceeds the threshold, the second telescopic rod 808 at the top of the movable sealing plug 806 causes the rectangular conductive plate 809 to contact the rectangular groove 7021 in the auxiliary circuit connector 702. At this point, the auxiliary circuit connector 702 is energized, causing the exhaust fan 6 at the bottom of the auxiliary exhaust pipe 3 to rotate. The rotation of the exhaust fan 6 then forces air from inside cabinet 1 into the auxiliary pressurized exhaust cone pipe 9. The hot air is compressed and sent into the exhaust pressure chamber 1003 through the pressure chamber 901, and then further discharged through the buzzer hole 1004 to improve the heat dissipation effect of the cabinet 1. At the same time, the buzzer hole 1004 discharges air and emits a buzzer warning to remind the staff to conduct safety inspection. Then, when the internal temperature of the cabinet 1 is normal, the movable sealing plug 806 descends, and the rectangular conductive plate 809 at the top of the second telescopic rod 808 stops connecting with the auxiliary circuit connector 702. At this time, the exhaust fan 6 at the bottom of the auxiliary exhaust pipe 3 is de-energized and stops rotating.

[0055] Then, when the internal temperature of cabinet 1 is lower than the low temperature threshold, the movable sealing plug 806 drives the rectangular conductive piece 809 at the top of the first telescopic rod 807 to disengage from the internal position of the connecting groove 7011 opened in the main circuit connector 701. At this time, the exhaust fan 6 at the bottom of the main exhaust pipe 2 is de-energized and stops rotating. At this time, the airflow inside cabinet 1 stops. Then, when the heat generated by the operation of the electrical components inside cabinet 1 is higher than the low temperature threshold, the exhaust fan 6 at the bottom of the main exhaust pipe 2 starts to operate normally with power.
