Description

Technical Field

[0001] This invention relates to the field of ring network box technology, specifically to an environmentally friendly primary and secondary integrated ring network box. Background Technology

[0002] In current power systems, integrated primary and secondary ring main units (RMUs) are widely used as important power distribution equipment in urban power grids and industrial power applications. However, existing technologies have revealed numerous problems during actual operation: Equipment maintenance is difficult: The location of high-level components inside the ring main unit is unique, and conventional maintenance methods require additional access equipment, such as portable ladders or lifting platform trucks. However, the operating space for these devices is limited in the narrow space around the ring main unit, and the equipment is prone to bumping into the ring main unit during movement, which not only increases maintenance time but also poses a threat to the personal safety of maintenance personnel. At the same time, the frequent use of large access equipment is costly and not conducive to efficient and low-cost daily operation and maintenance. Low heat dissipation efficiency: With the increase in power load, the heat generated by the equipment inside the ring main unit is constantly increasing. The condensers of traditional ring main unit air conditioning systems are mostly installed on the external side or top of the unit, directly exposed to the external environment. In hot summers or under high load conditions, the high external temperature hinders condenser heat dissipation, leading to reduced air conditioning efficiency and ineffective control of the internal temperature of the ring main unit. Overheating accelerates the aging of electrical equipment, reduces equipment lifespan, and increases the probability of failure. Drainage design flaws: Existing ring mainframe enclosures primarily rely on simple drainage holes at the bottom. During heavy rainfall or rising groundwater levels, the drainage rate is insufficient to meet the needs of water accumulation, easily leading to water buildup inside the enclosure. This water can soak electrical equipment, causing short circuits and severely impacting the safe and stable operation of the ring mainframe enclosure and the entire power system. Furthermore, while some ring mainframe enclosures are equipped with drainage pipes, they lack effective drainage mechanisms, resulting in poor drainage and similar water accumulation risks. Summary of the Invention

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an environmentally friendly integrated primary and secondary ring main unit that integrates lifting, drainage, and cooling functions. This improves maintenance convenience, air conditioning heat dissipation efficiency, and drainage capacity, solving the problems of difficult maintenance of high-level components, low heat dissipation efficiency of air conditioning condensers, and drainage design defects in existing ring main units.

[0004] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: An environmentally friendly primary and secondary integrated ring main unit includes a ring main unit comprising an outer casing and an inner casing, the ring main unit being fixedly installed on a base, and further comprising: A vertical shaft is installed on the base, and the vertical shaft is located in front of the door of the ring network box; A lifting device is installed inside the vertical shaft. The lifting device includes a cylinder installed in the middle of the vertical shaft. A lifting plate is fixed to the top of the cylinder's push rod. The lifting plate moves up and down on the vertical shaft. The air conditioning system has an evaporator pipe located inside the outer casing, and a condenser pipe located at the bottom of the vertical shaft, which is fixed to the side wall at the bottom of the vertical shaft. The drainage channel is located inside the base and connects to the bottom of the shaft.

[0005] Preferably, the shaft is provided with a partition, which is I-shaped. The partition includes an upper partition placed horizontally at the top, a middle partition placed vertically in the middle, and a lower partition placed horizontally at the bottom. The space below the upper partition in the shaft is divided into an upper chamber and a lower chamber by the lower partition. The upper chamber is divided into a blower chamber and an equipment chamber by the middle partition. The lower chamber is a cooling chamber for accommodating condenser pipes. The cylinder is installed in the equipment room, the push rod passes through the upper partition, and the upper partition is sealed on both the upper and lower sides. A blower is installed in the blower chamber and is fixed on the lower partition. The lower partition has a through hole corresponding to the air inlet of the blower, which connects to the cooling chamber.

[0006] Preferably, ventilation holes are provided on the partition plate, and an auxiliary plate is fixed on the push rod. The auxiliary plate slides up and down in the equipment room with the push rod. An external exhaust channel is also provided on the side wall of the shaft, and the external exhaust channel is connected to the exhaust box. When the auxiliary plate moves to its lowest position with the push rod, the ventilation hole and the external exhaust channel are located between the upper partition and the auxiliary plate. At this time, under the action of the blower, the cold and humid airflow from the drainage channel passes through the cooling chamber, the blower chamber, the ventilation hole, the external exhaust channel and the exhaust box in sequence to form an external circulation. When the auxiliary plate moves to its highest position with the push rod, the ventilation hole is located below the auxiliary plate, and the lower partition covers the external exhaust channel. At this time, under the action of the blower, the cold and humid airflow from the drainage channel passes through the cooling chamber, the blower chamber, the equipment room and the cooling chamber in sequence, forming an internal circulation.

[0007] Preferably, a movable block is slidably disposed inside the ventilation hole, and the end of the movable block near the blower chamber is pulled to the wall of the ventilation hole by a spring. An exhaust hole is provided on the side of the end of the movable block near the equipment chamber. When the blower is not running, the end of the movable block near the equipment room is hidden in the ventilation hole under the action of the spring, which does not affect the up and down movement of the auxiliary plate; When the blower starts, the airflow pushes the movable block to move within the equipment chamber. At this time, the end of the movable block protrudes into the equipment chamber, which limits the sliding of the auxiliary plate.

[0008] Preferably, the external exhaust channel is provided with two pipes, an upper pipe and a lower pipe. The upper pipe of the external exhaust channel is connected to the exhaust box, and the lower pipe of the external exhaust channel is connected to the cooling chamber.

[0009] Preferably, an inclined chamfer is provided on the lower surface of the movable block so that the movable block can be pushed back into the ventilation hole when the auxiliary plate rises.

[0010] Preferably, at least two shafts are provided on the base, each shaft is equipped with a partition, a lifting device and a blower, the lifting plates in multiple shafts are an integral structure, multiple push rods are connected and fixed to the bottom of a lifting plate, and the drainage channel connects to the bottom of multiple shafts.

[0011] Preferably, the condenser tubes are arranged in a serpentine or spiral shape at the bottom of the shaft.

[0012] Preferably, solenoid valves are installed in the upper and lower pipes of the external exhaust channel, and the solenoid valves are electrically connected to the electrical control cabinet.

[0013] Preferably, the electrical control cabinet is equipped with a timing module that automatically switches to internal circulation when the external circulation continues to run for a preset time.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides an environmentally friendly primary and secondary integrated ring main unit, which has the following beneficial effects: 1. This environmentally friendly integrated primary and secondary ring main unit incorporates a vertical shaft on its base. Firstly, the shaft accommodates the lifting device, facilitating maintenance of high-level components within the ring main unit. Secondly, the bottom of the shaft utilizes the cool, humid air inside to cool the condenser coils of the air conditioning system, reducing refrigeration costs and improving the ring main unit's adaptability to high-temperature environments. Finally, the bottom of the shaft connects to a drainage channel, enabling it to function as a drainage channel during heavy rain, enhancing the front drainage capacity of the ring main unit. This integrated lifting, drainage, and cooling functions improves maintenance convenience, air conditioning heat dissipation efficiency, and drainage capacity.

[0015] 2. This environmentally friendly primary and secondary fusion ring main unit uses an auxiliary plate fixed inside the push rod. First, the auxiliary plate slides against the inner wall of the equipment chamber, stabilizing the push rod. Second, when the lifting plate is not raised, the auxiliary plate is at the bottom, allowing the airflow generated by the blower to be discharged to the outside through the external exhaust channel, forming an external circulation and improving cooling efficiency. Finally, when the lifting plate is raised, the auxiliary plate is at the top, allowing the airflow generated by the blower to automatically be discharged into the cooling chamber below the auxiliary plate, forming an internal circulation. This prevents the discharge of gas during maintenance from affecting the maintenance experience of the personnel.

[0016] 3. This environmentally friendly primary and secondary fusion ring main unit uses a movable block installed inside the ventilation hole. When the blower is not running, the end of the movable block near the equipment chamber is hidden inside the ventilation hole under the action of the spring, without affecting the up and down movement of the auxiliary plate. When the blower starts, the airflow pushes the movable block to move inside the equipment chamber. At this time, the end of the movable block protrudes into the equipment chamber, which limits the sliding of the auxiliary plate. Thus, when the lifting plate moves to the highest position, starting the blower can use the movable block to prevent it from falling. The lifting plate can only be lowered when the blower is turned off, thus avoiding the airflow from being immediately discharged from the exhaust box after the lifting plate is lowered, which would affect the maintenance experience of the maintenance personnel.

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Example 1: This embodiment provides an environmentally friendly primary and secondary integrated ring network box, which has the following technical features.

[0032] Please see Figure 1-10 , An environmentally friendly primary and secondary integrated ring network box includes a ring network box 1, which includes an outer box 11 and an inner box 12. The ring network box 1 is fixedly installed on a base 2, and further includes: Vertical shaft 3 is installed on base 2, and the vertical shaft 3 is located in front of the door of ring network box 1; A lifting device 5 is installed inside the vertical shaft 3. The lifting device 5 includes a cylinder 54 installed in the middle of the vertical shaft 3. A lifting plate 51 is fixed to the top of the push rod 52 of the cylinder 54. The lifting plate 51 moves up and down on the vertical shaft 3. The air conditioning system has an evaporator pipe located inside the outer casing 11, and a condenser pipe 14 located at the bottom of the vertical shaft 3. The condenser pipe 14 is fixed to the bottom side wall of the vertical shaft 3. Drainage channel 6 is located inside base 2 and connects to the bottom of shaft 3.

[0033] Beneficially, by setting a vertical shaft 3 on the base 2, firstly, the vertical shaft 3 can not only accommodate the lifting device 5, thus facilitating the maintenance of components located at higher levels within the ring network box 1; secondly, the bottom of the vertical shaft 3 can utilize the internal cold and humid air to cool the condenser pipe 14 of the air conditioning system, reducing refrigeration costs and improving the adaptability of the ring network box 1 to high-temperature environments; finally, the bottom of the vertical shaft 3 is connected to the drainage channel 6, which can also serve as a drainage channel during heavy rain, improving the front drainage capacity of the ring network box 1. Integrating lifting, drainage, and refrigeration functions, it enhances maintenance convenience, air conditioning heat dissipation efficiency, and drainage capacity.

[0034] Furthermore, the bottom of the shaft 3 is provided with a drainage slope of not less than 1% from the edge to the drainage channel 6.

[0035] Furthermore, the surface of the lifting plate 51 is provided with anti-slip texture.

[0036] Furthermore, the inner wall of shaft 3 is constructed of reinforced concrete with a wall thickness of not less than 200 mm, or is made of high-strength corrosion-resistant metal material, such as 316 stainless steel, with a metal wall thickness of not less than 5 mm, to ensure the structural strength and waterproof performance of the shaft.

[0037] Furthermore, a protective sleeve is installed on the outside of the cylinder 54. The protective sleeve is made of insulating, waterproof and corrosion-resistant materials, such as a polytetrafluoroethylene coated metal sleeve. The length of the protective sleeve covers the cylinder body of the cylinder 54, and a drain hole with a diameter of 5-8 mm is provided at the bottom of the protective sleeve to promptly drain any water that may enter.

[0038] Furthermore, the base 2 is provided with a drain outlet, the height of which is higher than the upper surface of the base 2 and lower than the inner bottom surface of the ring network box 1. The drain outlet is connected to the bottom of the vertical shaft 3 and is used to drain water into the vertical shaft 3 when the water level is too high.

[0039] Furthermore, the ring main unit 1 is equipped with an independent electrical control cabinet, which is used to control the operation of the cylinder and monitor parameters such as the temperature of the condenser pipe of the air conditioning system and the humidity in the shaft. The electrical control cabinet has overload protection and short circuit protection functions, and is connected to the monitoring system of the ring main unit to upload data in real time.

[0040] Furthermore, the bottom of the ring network box 1 is provided with an overhead plate 13, which is fixed to the upper surface of the base 2. The ring network box 1 is suspended on the base 2 by the overhead plate 13, and drainage outlets are provided on the upper surface and sides of the overhead plate 13.

[0041] In an optional embodiment, a partition 4 is provided inside the shaft 3. The partition 4 is I-shaped and includes an upper partition 41 placed horizontally at the top, a middle partition 42 placed vertically in the middle, and a lower partition 43 placed horizontally at the bottom. The space inside the shaft 3 below the upper partition 41 is divided into an upper chamber and a lower chamber by the lower partition 43. The upper chamber is divided into a blower chamber 32 and an equipment chamber 33 by the middle partition 42. The lower chamber is a cooling chamber 31 for accommodating the condenser pipe 14. The cylinder 54 is installed in the equipment chamber 33, the push rod 52 passes through the upper partition 41, and the upper partition 41 is sealed on both the upper and lower sides. A blower 7 is installed inside the blower chamber 32. The blower 7 is fixed on the lower partition 43. The lower partition 43 has a through hole corresponding to the air inlet of the blower 7, which connects to the cooling chamber 31.

[0042] Furthermore, the cross-sectional size of the shaft 3 decreases gradually from top to bottom, and the lower partition 43 and the upper partition 41 are limited by steps on the side wall of the shaft 3.

[0043] In an optional embodiment, ventilation holes 421 are provided on the partition plate 42, and an auxiliary plate 53 is fixed on the push rod 52. The auxiliary plate 53 slides up and down in the equipment room 33 with the push rod 52. An external exhaust channel 331 is also provided on the side wall of the shaft 3, and the external exhaust channel 331 is connected to the exhaust box. When the auxiliary plate 53 moves to the lowest position with the push rod 52, the ventilation hole 421 and the external exhaust channel 331 are located between the upper partition plate 41 and the auxiliary plate 53. At this time, under the action of the blower 7, the cold and humid airflow from the drainage channel 6 passes through the cooling chamber 31, the blower chamber 32, the ventilation hole 421, the external exhaust channel 331 and the exhaust box in sequence to form an external circulation. When the auxiliary plate 53 moves to its highest position with the push rod 52, the ventilation hole 421 is located below the auxiliary plate 53, and the lower partition 43 covers the external exhaust channel 331. At this time, under the action of the blower 7, the cold and humid airflow from the drainage channel 6 passes through the cooling chamber 31, the blower chamber 32, the equipment chamber 33 and the cooling chamber 31 in sequence, forming an internal circulation.

[0044] The advantage is that by fixing the auxiliary plate 53 inside the push rod 52, firstly, the auxiliary plate 53 slides on the inner wall of the equipment chamber 33, which stabilizes the push rod 52; secondly, when the lifting plate 51 is not raised, the auxiliary plate 53 is also at the bottom, and the airflow generated by the blower 7 is discharged to the outside through the external exhaust channel 331 to form an external circulation, which improves the cooling efficiency; finally, when the lifting plate 51 is raised, the auxiliary plate 53 is at the top, and the airflow generated by the blower 7 is automatically discharged into the cooling chamber 31 through the bottom of the auxiliary plate 53 to form an internal circulation, avoiding the discharge of gas to the outside during maintenance and affecting the maintenance experience of maintenance personnel.

[0045] Furthermore, the exhaust box is mounted on the base 2 and is 1 meter above the ground.

[0046] Furthermore, an air purifier is installed inside the external exhaust channel 331 or in the exhaust box.

[0047] Furthermore, the cylinder 54 is mounted on the lower partition 43 in an overhead manner, and the lower partition 43 is provided with a ventilation port corresponding to the position of the cylinder 54, which connects the equipment chamber 33 and the cooling chamber 31.

[0048] In an optional embodiment, a movable block 8 is slidably disposed inside the ventilation hole 421. The end of the movable block 8 near the blower chamber 32 is pulled to the wall of the ventilation hole 421 by a spring. An exhaust hole 81 is provided on the side of the end of the movable block 8 near the equipment chamber 33. When the blower 7 is not started, under the action of the spring, the end of the movable block 8 near the equipment chamber 33 is hidden in the ventilation hole 421, which does not affect the up and down movement of the auxiliary plate 53. When the blower 7 is started, the airflow pushes the movable block 8 to move inside the equipment chamber 33. At this time, the end of the movable block 8 protrudes into the equipment chamber 33, which limits the sliding of the auxiliary plate 53.

[0049] Advantageously, by setting a movable block 8 inside the ventilation hole 421, when the blower 7 is not started, the end of the movable block 8 near the equipment chamber 33 is hidden inside the ventilation hole 421 under the action of the spring, which does not affect the up and down movement of the auxiliary plate 53. When the blower 7 is started, the movable block 8 is pushed to move inside the equipment chamber 33 under the action of the airflow. At this time, the end of the movable block 8 protrudes into the equipment chamber 33, which limits the sliding of the auxiliary plate 53. Thus, when the lifting plate 51 moves to the highest position, starting the blower 7 can use the movable block 8 to prevent it from falling. Only when the blower 7 is turned off can the lifting plate 51 be lowered, thus avoiding the airflow from being immediately discharged from the exhaust box after the lifting plate 51 is lowered, which would affect the maintenance experience of the maintenance personnel.

[0050] In an optional embodiment, the external exhaust channel 331 is connected to two pipes, an upper pipe and a lower pipe. The upper pipe of the external exhaust channel 331 is connected to the exhaust box, and the lower pipe of the external exhaust channel 331 is connected to the cooling chamber 31.

[0051] It should be noted that, through the above improvements, when the upper partition 41 leaks water, there will be water accumulation above the auxiliary plate 53. When the auxiliary plate 53 rises to fit the lower surface of the upper partition 41, it will squeeze the water accumulation on the auxiliary plate 53 into the external exhaust channel 331 for discharge.

[0052] In an optional embodiment, an inclined chamfer is provided on the lower surface of the movable block 8 so that when the auxiliary plate 53 rises, it can push the movable block 8 back into the ventilation hole 421.

[0053] It should be noted that, with the above improvements, it is not necessary to turn off the blower 7 before the lifting plate 51 is raised.

[0054] In an optional embodiment, at least two shafts 3 are provided on the base 2. Each shaft 3 is provided with a partition 4, a lifting device 5 and a blower 7. The lifting plates 51 in the multiple shafts 3 are an integral structure. Multiple push rods 52 are connected and fixed to the bottom of a lifting plate 51. The drainage channel 6 connects to the bottom of the multiple shafts 3.

[0055] In an optional embodiment, the condenser tubes 14 are arranged in a serpentine or spiral shape at the bottom of the shaft 3.

[0056] In an optional embodiment, solenoid valves are respectively installed in the upper and lower pipes in the external exhaust channel 331, and the solenoid valves are electrically connected to the electrical control cabinet.

[0057] It should be noted that the electrical control cabinet controls the opening or closing of the solenoid valves of the corresponding pipelines according to the position of the auxiliary board 53, thereby realizing the automatic switching of pipelines.

[0058] In an optional embodiment, a timing module is installed in the electrical control cabinet, which automatically switches to the internal circulation when the external circulation continues to run for a preset time.

[0059] It should be noted that when the external circulation continues to run for more than 1-3 hours, it will automatically switch to internal circulation for 5-10 minutes to balance the humidity inside shaft 3.

[0060] Furthermore, the cylinders 54 in multiple shafts 3 are synchronously controlled by the same electrical control cabinet. The electrical control cabinet is equipped with a synchronous control module to ensure that the lifting speed of multiple push rods 52 is consistent and the error does not exceed 5mm / s.

[0061] Furthermore, a pressure sensor is installed at one end of the movable block 8 near the vertical shaft 3. The pressure sensor is electrically connected to the electrical control cabinet. When the auxiliary plate 53 contacts the movable block 8, the pressure sensor transmits a signal to the electrical control cabinet, which then issues a prompt sound to remind the staff that the auxiliary plate 53 has reached the limit position.

[0062] Furthermore, the outer casing 11 of the ring network box 1 is coated with a reflective and heat-insulating coating with a thickness of 0.1-0.3 mm to reduce the impact of the external ambient temperature on the interior of the ring network box 1.

[0063] Furthermore, the drainage channel 6 adopts a dual-mode drainage system of "terrain diversion + intelligent pump drainage", specifically including: The drainage channel 6 starts with a 2%-3% slope along the direction of water flow in the area connecting the bottom of the vertical shaft. It is made of concrete and has been treated to prevent seepage. A cobblestone filter layer with a particle size of 5-10cm is laid at the bottom, and a permeable geotextile is covered on top of the filter layer. This not only utilizes the natural terrain for drainage but also filters impurities in the water to prevent the channel from being blocked. Intelligent pump section: When the elevation difference between the end of drainage channel 6 and the municipal drainage network is less than 1.5 meters, a submersible sewage pump with a power of 0.75-1.5kW is installed at the end of the channel. The pump inlet is equipped with a stainless steel filter screen with a hole diameter of 3-5mm. The pump is electrically connected to the electrical control cabinet. Linkage control: Two to three sets of liquid level sensors are installed at 5-meter intervals within drainage channel 6. When the liquid level sensor detects that the water flow cannot drain naturally and the liquid level does not drop for 10 minutes, the electrical control cabinet will automatically start the submersible sewage pump. When the liquid level is lower than the lowest sensor, the pump will automatically shut down after a 30-second delay to avoid frequent start-stop. Emergency drainage: An emergency drainage interface is reserved at the end of drainage channel 6, which can be connected to a temporary drainage pipe during heavy rain and extreme weather to divert the accumulated water to a distant low-lying area or an emergency water storage tank.

[0064] Working principle of the lifting device: The cylinder 54 in the vertical shaft 3 drives the push rod 52 to raise and lower the lifting plate 51. Workers can use the lifting plate 51 to reach the high-level components in the ring network box 1 for maintenance. The electrical control cabinet controls the operation of the cylinder, and the synchronous control module ensures that the lifting speed of the push rods in multiple vertical shafts is consistent, and has overload and short circuit protection functions.

[0065] Working principle of the air conditioning refrigeration system: The evaporator pipes of the air conditioning system are located inside the outer casing 11 of the ring network box 1, and the condenser pipe 14 is installed in the cooling chamber 31 at the bottom of the vertical shaft 3. The blower 7 in the vertical shaft 3 is located in the blower chamber 32 and draws cold and humid air from the cooling chamber 31 through the through hole of the lower partition 43 to cool the condenser pipe 14 and improve the air conditioning refrigeration efficiency. The airflow circulation mode switches according to the position of the lifting plate 51: When the lifting plate 51 is not raised (the auxiliary plate 53 is at the lowest position), the airflow forms an external circulation through the blower chamber 32, the ventilation hole 421 of the middle partition 42, the external exhaust channel 331 on the side wall of the vertical shaft 3, and the exhaust box, which enhances heat dissipation. When the lifting plate 51 is raised (the auxiliary plate 53 is at the highest position), the airflow returns to the cooling chamber 31 through the blower chamber 32 and the equipment room 33 to form an internal circulation, avoiding affecting maintenance personnel.

[0066] The drainage system works as follows: The bottom of the vertical shaft 3 has a drainage slope of no less than 1% from its edge to the drainage channel 6. During heavy rain, this slope acts as a drainage channel, quickly removing accumulated water. The drainage outlets on the base 2 (higher than the upper surface of the base 2 but lower than the inner bottom surface of the ring mesh box 1) drain water into the vertical shaft 3 when the water level is too high. The overhead plate 13 at the bottom of the ring mesh box 1 (fixed to the base 2) further assists in drainage through surface and side drainage outlets.

[0067] Shaft Structure and Auxiliary Function Principles: The inner wall of shaft 3 is made of reinforced concrete (wall thickness ≥ 200mm) or high-strength corrosion-resistant metal (such as 316 stainless steel, wall thickness ≥ 5mm) to ensure structural strength and waterproofing. I-shaped partitions 4 (upper partition 41, middle partition 42, lower partition 43) divide shaft 3 into cooling chamber 31, blower chamber 32, and equipment chamber 33, achieving functional zoning. The movable block 8 inside the ventilation hole 421 protrudes into the equipment chamber 33 when the blower 7 starts, limiting the auxiliary plate 53 and preventing it from falling. The air purifier in the external exhaust channel 331 purifies the exhaust gas, and the solenoid valves of the upper and lower pipes (controlled by the electrical control cabinet) achieve automatic switching. The electrical control cabinet monitors parameters such as the temperature of the air conditioner condenser pipes and the humidity inside shaft 3. After 1-3 hours of continuous external circulation, the timing module automatically switches to internal circulation (5-10 minutes) to balance the humidity.
