Description

Distribution cabinets, which include power distribution cabinets, lighting distribution cabinets, and metering cabinets, are the final stage of the power distribution system and a crucial component of the IoT.
[0003] However, the existing outdoor IoT distribution cabinets are exposed to the sun and rain and snow, which will lead to a large temperature difference between the inside and outside of the cabinet.

For example, they may refer to fixed or detachable connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention.
[0027] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0028] The following is based on Figures 1 to 5 The present invention introduces an IoT power distribution cabinet provided by the present invention using two embodiments. The IoT power distribution cabinet is installed in a cable trench and uses the relatively constant temperature air in the cable trench to insulate the space inside the IoT power distribution cabinet.
[0029] Example 1
[0030] Reference Figure 1 and Figure 2As shown, the Internet of Things power distribution cabinet provided by the present invention includes a cabinet body 1, a base 2 and a communication device 8. Among them, the base 2 is fixedly arranged on the cable trench, the cabinet body 1 is fixedly arranged on the base 2, and the communication device 8 is arranged in the cabinet body 1.
[0031] Specifically, if Figure 2 As shown, the cabinet 1 is provided with a first wall panel 12 and a second wall panel 10. Both the first wall panel 12 and the second wall panel 10 are arranged vertically and spaced apart horizontally, thereby dividing the cabinet 1 from the outside inward into a ventilation groove 7, a liquid reservoir 5, and a power distribution chamber 11. The ventilation groove 7 and the liquid reservoir 5 are on either side of the first wall panel 12, and the liquid reservoir 5 and the power distribution chamber 11 are on either side of the second wall panel 10. The top of the ventilation groove 7 is closed, and the bottom of the ventilation groove 7 forms an air inlet on the bottom surface of the cabinet 1. The constant temperature air in the cable trench enters the ventilation groove 7 through this air inlet. The liquid reservoir 5 forms a leak 4 on the top surface of the cabinet 1, through which rainwater can flow into the liquid reservoir 5 for storage. A gap 9 is provided through the bottom of the first wall panel 12, connecting the ventilation groove 7 and the liquid reservoir 5. The power distribution chamber 11 stores electrical equipment and is also an important space for heat preservation and moisture retention in the present invention. Optionally, in this embodiment, the outer wall panels constituting the cabinet body 1 and the first wall panel 12 and the second wall panel 10 located inside the cabinet body 1 are all made of stainless steel, thereby being able to prevent rust.
[0032] The communicating vessel 8 is arranged in the vent groove 7, specifically, as Figure 3 As shown, the communicating vessel 8 includes a tube body 802, the height of which is less than that of the vent groove 7. The bottom end of the tube body 802 is fixed in the air inlet. A pressure ring groove 801 is formed between the outer wall of the tube body 802 and the first wall plate 12. The pressure ring groove 801 is connected to the liquid storage tank 5 through the gap 9. Since the height of the tube body 802 is less than that of the vent groove 7, the space inside the tube body 802 can communicate with the pressure ring groove 801 outside the tube body 802 through the upper space in the vent groove 7 that is higher than the communicating vessel 8. As a result, the relatively constant temperature and high pressure air in the cable trench that enters through the tube body 802 can come into contact with the rainwater in the liquid storage tank 5 through the pressure ring groove 801 and the gap 9, thereby achieving a relatively balanced pressure state and preventing rainwater in the liquid storage tank 5 from entering the vent groove 7.
[0033] Continue to refer to Figure 2 As shown, an air pump 701 is provided in the base 2, the air intake of the air pump 701 is connected to the cable trench, and the air outlet of the air pump 701 is connected to the tube body 802. Driven by the air pump 701, the air in the cable trench passes through the tube body 802 and enters the ventilation groove 7.
[0034] During use, for example, the air pump 701 draws constant-temperature, high-pressure air from the cable trench and delivers it to the ventilation tank 7 through the communication tube 8. Because the rainwater stored in the liquid reservoir 5 forms a liquid seal at the gap 9, the air pressure in the ventilation tank 7 is maintained at a preset pressure. As a result, the rainwater in the liquid reservoir 5 is maintained at a preset height through the gap 9, forming a water wall within the cabinet 1. Simultaneously, the constant-temperature, high-pressure air in the ventilation tank 7 continuously exchanges heat with the rainwater in the liquid reservoir 5, maintaining the temperature of the liquid reservoir 5 at a preset temperature. This insulates the distribution chamber 11 and maintains a stable temperature within the distribution chamber 11. That is to say, by arranging the ventilation groove 7 and the liquid storage tank 5 in the cabinet body 1 of the Internet of Things power distribution cabinet, the relatively constant temperature and high-pressure air in the cable trench is extracted and heat exchanged with the water in the liquid storage tank 5 to form a constant temperature and heat-insulating water wall, and a three-layer two-stage heat exchange is formed with the distribution cavity 11. Therefore, no matter whether the external environment is extremely hot or extremely cold, the air temperature in the distribution cavity 11 can be kept at a constant temperature. At the same time, it also avoids the imbalance of dryness and wetness, protects the power equipment inside the distribution cavity 11, avoids damage to the power equipment, and improves the service life of the power equipment.
[0035] Optionally, since the air drawn into the cable trench is relatively humid, condensation will form on the inner wall of the ventilation groove 7. Therefore, in this embodiment, if Figure 5 As shown, the bottom of the communicating vessel 8 also includes a flange 803, which forms a sealed connection with the side wall of the ventilation groove 7 to prevent condensed water generated in the ventilation groove 7 from flowing into the air pump 701 and affecting the service life of the air pump 701. At the same time, the tube body 802 forms a duct-like wind pressure, which will reduce the water droplets on the vertical line. For example, in this embodiment, the ventilation groove 7 is arranged in an annular structure, and the communicating vessel 8 also has a corresponding annular structure to achieve a sealed connection and prevent water leakage at the connection.
[0036] Optionally, in this embodiment, if Figure 1 As shown, a roof 3 is provided on the top of the cabinet 1, and the roof 3 has an inclined surface, and a leakage opening 4 is provided on the inclined surface. By providing the inclined surface, rainwater can be converged to the leakage opening 4, thereby accelerating the rainwater accumulation efficiency in the liquid storage tank 5.
[0037] Continue to refer to Figure 2 As shown, in this embodiment, the ceiling 3 is a double-layer structure, forming a heat-insulating space inside, which can reduce the heat exchange between the distribution cavity 11 below and the outside world.
[0038] Furthermore, in this embodiment, the leak 4 is provided with a screen structure (not shown in the figure), which is used to coarsely filter the rainwater entering the liquid storage tank 5 to prevent the accumulation of dirt in the liquid storage tank 5. In this embodiment, the screen structure is made of a screen, which is inexpensive and has low replacement cost.
[0039] Furthermore, in this embodiment, a ventilation groove 7, a liquid storage tank 5 and a communicating vessel 8 are defined as a group of heat exchange structures, and multiple groups of heat exchange structures are arranged in the cabinet 1. For example, when the cabinet 1 is similar to a cube, a group of heat exchange structures are arranged on three sides of the cabinet 1, and a cabinet door is opened on the remaining side. Optionally, the ceiling 3 has multiple inclined planes with different inclination directions, and multiple groups of heat exchange structures are arranged one by one below the multiple inclined planes, and each inclined plane is provided with a leak 4. It should be noted that the number of heat exchange structures is determined according to actual needs, and opening a cabinet door through the heat exchange structure will not affect the operation of the heat exchange structure. As long as the ventilation groove 7 and the liquid storage tank 5 are functioning normally, and as long as a three-layer two-stage heat exchange can be formed, it falls within the scope of protection of the present invention.
[0040] Since the air extracted is from the inside of the cable trench, which is usually located in a deeper shaft, the air temperature inside the cable trench is low in hot weather. The ventilation groove 7 located on the outer layer blocks the temperature while exchanging heat with the temperature inside the liquid storage tank 5. Similarly, in cold weather, the temperature of the cable trench is higher than the outdoor temperature. Therefore, in rainy and snowy weather, the air pump 701 can be continuously started to ensure the clearing of snow and rainwater on the ceiling 3, which is convenient for the staff to control based on the actual weather season and temperature.
[0041] Example 2
[0042] Based on the first embodiment, this embodiment is provided with a lighting component based on the constant temperature technology in the cabinet 1, which can achieve the effect of utilizing the water source in the liquid storage tank 5 to form hydraulic lighting or hydraulically activated lighting, and can be further controlled according to lighting needs. In particular, when the IoT power distribution cabinet outdoors is in a power-off state and needs emergency repair at night, it can automatically generate an electric lighting effect, thereby improving the efficiency of emergency repairs.
[0043] Specifically, if Figure 4 As shown, the lighting assembly 6 includes a lamp body 606, a mounting box 607, a positive pole 604, a negative pole 603, and an on-off valve 605. The mounting box 607 is disposed within the power distribution chamber 11, forming a water storage chamber 608 within the mounting box 607. The lamp body 606 is connected to the outer wall of the mounting box 607. The positive pole 604 and the negative pole 603 are both disposed within the water storage chamber 608, forming a removable, inlaid seal connection with the mounting box 607. The connection is equipped with a rubber sealing ring to prevent rainwater leakage. One end of the positive pole 604 and one end of the negative pole 603 pass through the mounting box 607 to electrically connect to the positive and negative poles of the lamp body 606, respectively. The mounting box 607 is provided with a water inlet, which is arranged higher than the positive pole 604 and the negative pole 603.
[0044] During use, for example, the opening and closing valve 605 is opened, the water inlet is opened, and the water in the liquid storage tank 5 can enter the water storage chamber 608 through the water inlet, connecting the positive electrode 604 and the negative electrode 603, thereby lighting the lamp body 606. Optionally, in this embodiment, the positive electrode 604 is made of a millstone material, and the negative electrode 603 is made of a magnesium alloy material, forming a graphite-magnesium primary battery to power the lamp body 606, and the positive electrode 604 and the negative electrode 603 are both threadedly connected to the installation box 607. Of course, it should be noted that in some parallel embodiments, the energy for the lamp body 606 can also be provided by a dedicated power supply line, and the positive electrode 604 and the negative electrode 603 are used to control the on and off of the power supply line, creating a water-powered lighting effect, which also falls within the scope of protection of the present invention.
[0045] Optionally, in this embodiment, the positive pole 604 is positioned higher than the negative pole 603. By adjusting the height of the positive and negative poles, the sensitivity of the lamp body can be adjusted. It is reasonable to speculate that when the positive pole 604 and the negative pole 603 are positioned at the same, lower height, a small amount of water can connect the positive pole 604 and the negative pole 603. However, when the positive pole 604 and the negative pole 603 are positioned at different heights, more water needs to enter the water storage chamber 608 to connect the positive pole 604 and the negative pole 603, thereby illuminating the lamp body 606. This avoids the phenomenon of a small amount of water entering the installation box 607 due to poor sealing, thereby igniting the lamp body 606 by mistake.
[0046] Alternatively, as Figure 2 As shown, a through hole connected to the water inlet is provided on the second wall panel 10 between the liquid reservoir 5 and the power distribution chamber 11. The lighting assembly 6 also includes an extended water storage member 602. One end of the extended water storage member 602 passes through the above-mentioned through hole and is fixedly connected to the water inlet. The extended water storage member 602 forms a water storage space 601 located within the liquid reservoir 5. The water storage space 601 has a water storage port opening upward. When the opening and closing valve 605 opens the water inlet, the water in the water storage space 601 can enter the water storage chamber 608 through the through hole and the water inlet. By providing the extended water storage member 602, even if the liquid level in the liquid reservoir 5 is insufficient, the lamp body 606 can still be illuminated by some rainwater stored in the water storage space 601.
[0047] Specifically, the extended water storage member 602 comprises a cube with openings on two adjacent sides, the first opening facing upward and the second opening communicating with the aforementioned through-hole. When rainwater enters the liquid reservoir 5 through the leak 4, at least some of the rainwater enters the water storage space 601 formed within the cube through the first opening. When the on-off valve 605 opens the water inlet, the water within the water storage space 601 can pass through the through-hole and the water inlet into the water storage chamber 608. Of course, it should be noted that the aforementioned shape of the extended water storage member 602 is merely an optional option; any configuration that can form the water storage space 601 falls within the scope of the present invention.
[0048] Furthermore, the lighting assembly 6 also includes a water pump 609. The water inlet of the water pump 609 is disposed in the water storage chamber 608 and is disposed at a height lower than at least one of the positive electrode 604 and the negative electrode 603. The water outlet of the water pump 609 is connected to the liquid storage tank 5. By providing the water pump 609, the water in the water storage chamber 608 can be drained, disconnecting the electrical connection between the positive electrode 604 and the negative electrode 603, so that the lamp body 606 is illuminated according to a preset method, thereby avoiding the lamp body 606 being constantly illuminated and increasing energy consumption. It should be noted that when the positive electrode 604 and the negative electrode 603 form a graphite-magnesium primary battery, the water in the water storage chamber 608 can be drained by providing the water pump 609, which can stop the primary battery reaction and extend the service life of the negative electrode 603.
[0049] Further, if Figure 2 As shown, there are multiple lighting assemblies 6, each mounted on different inner wall surfaces of the power distribution cavity 11. Alternatively, in this embodiment, there are two lighting assemblies 6, each mounted on two opposing inner wall surfaces. The water in the liquid reservoir 5 is used to further form a graphite-magnesium primary battery in the lighting assembly 6, thereby achieving a better lighting effect with less energy consumption.
[0050] Optionally, the cabinet 1 further includes a control module, which includes an MCU microcontroller chip, a clock chip, a current sensor, and a travel switch. The control module is electrically connected to the opening and closing valve 605, the lamp body 606, the water pump 609, and the air pump 701, respectively. The current sensor is used to sense the current of the lamp body 606, the travel switch is used to sense the switch state of the cabinet door of the cabinet 1, and the clock chip is used to control the intermittent operation of the air pump 701. After the air pump 701 stops due to the control of the clock chip, the air inside the ventilation groove 7 will be slowly released from the air pump 701 at the vent hole based on the size of the cable trench and the gap 9. The water level of the communicating vessel 8 will continue to rise according to the gap 9 and the loss of internal air pressure. After a certain period of time, the air pump 701 will start again, sucking in a large amount of air from the cable trench, and increasing the internal pressure again to achieve air circulation and water circulation. It should be noted that the clock chip controls the start and stop frequency of the air pump 701 to ensure that there is sufficient constant temperature high-pressure gas in the ventilation groove 7 to exchange heat with the rainwater in the liquid storage tank 5, and to maintain the rainwater in the liquid storage tank 5 at a certain height to prevent excessive rainwater from entering the pressure ring groove 801 through the gap 9.
[0051] Furthermore, the cabinet 1 further includes a display screen 101, which can display the relevant conditions inside the cabinet 1. For example, in this embodiment, the display screen 101 is set on the cabinet door for easy viewing from the outside. Of course, in some other embodiments, the display screen 101 can also be installed inside the cabinet 1 to extend the service life of the display screen 101.
[0052] During routine inspection of cabinet 1, due to the presence of water in water storage space 601 of extended water storage member 602, opening the cabinet door triggers a travel switch, which in turn activates on / off valve 605. Water from water storage space 601 enters water storage chamber 608, connecting positive electrode 604 and negative electrode 603, thereby illuminating lamp 606. A current sensor senses the current and closes on / off valve 605. When the travel switch is activated again by closing the cabinet door, water pump 609 activates, lowering the water level in water storage chamber 608 until the current sensor no longer senses current flowing to lamp 606. This ensures that lamp 606 is not constantly on, reducing energy consumption. In the event of an emergency repair, since the cabinet 1 is usually powered off, the opening and closing valve 605 will be in a normally open state due to the power outage, and the water source inside the water storage space 601 will directly enter the water storage chamber 608, causing the lamp body 606 to light up for a long time. In the absence of electricity, it can still provide lighting for the interior of the cabinet 1, and provide corresponding brightness when repairing the power distribution cabinet at night. Optionally, in this embodiment, the limit switch is set in the handle 102 on the cabinet door. The operator turns the handle 102 and unlocks the cabinet door, which can light up the lamp body 606. Of course, in some other embodiments, the limit switch can also be set between the cabinet door and the cabinet 1 and triggered by the rotation of the cabinet door. The present invention does not specifically limit the installation position of the limit switch.
[0053] Since the air extracted is from the inside of the cable trench, which is usually located in a deeper shaft, the air temperature inside the cable trench is low in hot weather. The ventilation groove 7 located on the outer layer blocks the temperature while exchanging heat with the temperature inside the liquid storage tank 5. Similarly, in cold weather, the temperature of the cable trench is higher than the outdoor temperature. Therefore, when facing rainy and snowy weather, the air pump 701 can be continuously started to ensure the clearing of snow and rainwater on the ceiling 3. This effect can be adjusted by the staff based on the control module, which is convenient for control according to the actual weather season and temperature.
[0054] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
