Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ring main unit, in particular to a modular intelligent environmental protection gas ring main unit. BACKGROUND

[0002] The ring main unit is a group of high-voltage switchgear installed in a steel plate metal cabinet or made into a spliced interval type ring network power supply unit. The core part adopts load switch and fuse. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, power supply safety, etc. It is widely used in power distribution stations and box-type substations of load centers such as urban residential areas, high-rise buildings, large public buildings, and factory enterprises. The ring main unit is usually spliced and connected to form a spliced interval type modular ring network power supply unit.

[0003] For the above-mentioned prior art, the spliced interval type modular ring main unit adopts a ring main unit mode of connecting parts to each other to facilitate subsequent disassembly and assembly. However, gaps exist at the connections of the parts, and thus water vapor in the environment easily enters the gaps, causing moisture problems. After a long time, water vapor easily enters the cabinet from the gaps at the connections of the parts, causing the internal electrical units to be damp, and seriously causing damage to the electrical units. In addition, the gaps between the ring main units easily cause heat accumulation, causing the heat generated by the ring main units to be transmitted between adjacent ring main units, resulting in difficult heat dissipation, and thus the heat inside the ring main units continuously accumulates, causing the electrical lines to be damaged by high temperature.

[0004] In addition, the current splicing method of the modular ring main unit is not convenient to move. Before moving, it needs to be disassembled and then reassembled, resulting in cumbersome moving work. At the same time, the current splicing method requires multiple mechanical structures to be completed, and needs to be manually assisted throughout the operation, which is complicated to operate.

In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present application. Example 1

[0034] Further comprising air pump 201, mounting plate 202, first clamping plate 203, sealing element 204, connecting plate 205 and second clamping plate 206; Each air slot 2004 is provided with an air pump 201; Each cabinet 2 is provided with a mounting plate 202; Each cabinet 2 is connected with a first clamping plate 203, and the first clamping plate 203 is provided with a sliding groove; Each first clamping plate 203 is flexibly connected with a sealing element 204, and the sealing element 204 is connected with the mounting plate 202 through the electric telescopic rod, the fixed part of the electric telescopic rod is connected with the mounting plate 202, the telescopic part of the electric telescopic rod is connected with the sealing element 204, and the air pump 201 is connected with the first clamping plate 203 through the air pipe; Each cabinet 2 is connected with a connecting plate 205, and the connecting plate 205 on each cabinet 2 is located away from the first clamping plate 203, and the connecting plate 205 and the first clamping plate 203 on every two left and right adjacent cabinets 2 are located in the same vertical axis direction; Each connecting plate 205 is connected with a second clamping plate 206 through an electric telescopic rod, the fixed part of the electric telescopic rod is connected with the connecting plate 205, the telescopic part of the electric telescopic rod is connected with the second clamping plate 206, and the size of the second clamping plate 206 is consistent with the size of the sliding groove in the first clamping plate 203.

[0035] Further comprising a ventilation system 103; The base 1 is provided with a ventilation system 103, and the ventilation system 103 is provided with a discharge port 10301 for discharging rainwater on the surface, an air inlet pipe 10302 for air inlet, and a discharge pipe 10303, and the ventilation system 103 is provided with a fan for ventilation.

[0036] The initial height of the discharge port 10301 lower end is consistent with the height of the top surface of the supporting hollow bottom plate 102, so that the rainwater and impurities falling on the top surface of the supporting hollow bottom plate 102 can be discharged in time through the discharge port 10301.

[0037] The sealing element 204 and the first clamping plate 203 are connected through a corrugated compensator for the contraction movement of the sealing element.

[0038] The working of the application is as follows:

[0039] The required number of ring network cabinets is confirmed by artificial, and the two cabinets 2 are placed in a symmetrical manner, the two cabinets 2 on the bottom layer are placed on the supporting hollow bottom plate 102, the arc-shaped groove 2002 of the two cabinets 2 stacked upwards is aligned with the position of the arc-shaped protrusion 2001 of the two cabinets 2 below, and they are clamped with each other, such as Figure 1As shown in the state, thus, the preliminary assembly of the cabinet body 2 is completed, since each cabinet body 2 is provided with an arc-shaped protrusion 2001 at the top, and the arc-shaped protrusion 2001 is located at the joint of two adjacent cabinet bodies 2, when the top is contacted with rainwater, the rainwater can be guided to the side away from the arc-shaped protrusion 2001 through the arc-shaped protrusion 2001, avoiding the penetration of rainwater into the gap, causing damp.

[0040] After the preliminary assembly is completed, control each air pump 201 to open, and continuously pump the groove through the air pipe connected to the first clamping plate 203, at the same time, control the electric telescopic rod connected to the second clamping plate 206 to drive it to move towards the groove, so that the second clamping plate 206 is completely moved into the groove of the first clamping plate 203, and at the same time, control the electric telescopic rod connected to the sealing element 204 to drive it to move towards the first clamping plate 203, so that the corrugated compensator connected between them is contracted, at this time, due to the continuous pumping of the air pump 201 and the movement of the second clamping plate 206, the gas in the groove of the first clamping plate 203 is squeezed and pumped away, and the gas between the sealing element 204 and the first clamping plate 203 is pumped away, keeping the space without gas, thereby realizing the subsequent assembly work of the cabinet body 2, at the same time, since it is in the state of gas pumping, and through the clamping of the second clamping plate 206 and the groove of the first clamping plate 203, the gap of the assembled part can be sealed again, avoiding the problem of damp caused by the penetration of water vapor, it should be noted that at this time, the outside air can be prevented from entering through the corrugated compensator, so as to ensure the complete sealing.

[0041] When the assembled cabinet body 2 needs to be disassembled, the groove can be inflated through the air pump 201 of each cabinet body 2, at the same time, control the telescopic rod connected to the second clamping plate 206 to drive it to move away from the groove, and control the electric telescopic rod connected to the sealing element 204 to drive it to move towards the side close to the mounting plate 202, at the same time, the corrugated compensator is elongated, due to the inflation of the air pump 201, the above-mentioned parts return to the initial state, as shown in the state, Figure 3 and Figure 4 Subsequently, the disassembly work of the assembled cabinet body 2 can be completed by artificial carrying, and the support pulley of the base 1 can drive the cabinet body 2 to move at any time.

[0042] When the ring main unit is in a working state, rainwater falls on the surface of the base 1, and the surface rainwater can be discharged through the drain port 10301, and part of the rainwater can be discharged from the ventilation system 103 through the discharge pipe 10303. It should be noted that the initial height of the lower end of the drain port 10301 is consistent with the height of the top surface of the supporting hollow bottom plate 102, so that the rainwater and impurities falling on the top surface of the supporting hollow bottom plate 102 can pass through the drain port 10301 in time, avoiding the problem that the lower cabinet 2 is easily damp due to long-term residue. At the same time, when the environment is in high temperature and dry, part of the rainwater is left in the ventilation system 103 and is in a dark place, so the inside is a damp and cold space. At this time, the outside air can be introduced into the inside of the ventilation system 103 through the air inlet pipe 10302 by the internal fan of the ventilation system 103, then the outside air is cooled, and the cooled gas is blown out from the drain port 10301, so that the cooled gas contacts the surrounding of the cabinet 2, thereby cooling the surface of the cabinet 2 and avoiding the risk of high-temperature shutdown due to long-term work. Embodiment 2

[0043] On the basis of embodiment 1, as shown in Figures 5-10 the flow guide plate 301, the rotating shaft 302 and the motor 303 are included; each cabinet 2 is provided with a second air slot 2005 at the top, and each second air slot 2005 is in communication with a corresponding air pump 201 through a communication pipe 20101; each second air slot 2005 is provided with a flow guide plate 301 inside, and a ventilation port 30101 is formed between the flow guide plate 301 and the arc-shaped protrusion 2001, and the ventilation port 30101 is in communication with the second air slot 2005; each flow guide plate 301 is fixedly connected with a rotating shaft 302, and each rotating shaft 302 is rotatably connected with the second air slot 2005; each cabinet 2 is provided with a motor 303 at the top, and the output end of each motor 303 is fixedly connected with a rotating shaft 302.

[0044] As shown in Figure 10 the flow guide concave surface 30102 is arranged on the flow guide plate 301, so that the airflow passing through is guided to the surface of the arc-shaped protrusion 2001.

[0045] Further including a connecting pipe 401; each cabinet 2 is provided with a first air slot 2003 at the bottom; each cabinet 2 is provided with a connecting pipe 401, and the connecting pipe 401 is in communication with the first air slot 2003; the air pump 201 is provided with an air pipe at the bottom, which is in communication with the air slot 2004, for sucking the air inside the air slot.

[0046] Further including an air nozzle 402; each cabinet 2 is provided with a plurality of air nozzles 402 symmetrically distributed front and back at the bottom, and each air nozzle 402 is in communication with the first air slot 2003, and the output direction of each air nozzle 402 is towards the outside of the cabinet 2.

[0047] The present application works as follows:

[0048] When the ambient temperature is high, and the air flow in the environment is small, the top surface of the uppermost cabinet 2 is irradiated by the sun, causing heat accumulation and difficulty in dissipation, which can easily cause the internal temperature of the cabinet 2 to rise over time, causing damage to the equipment. Therefore, the motor 303 can be controlled to drive the flow guide plate 301 and the shaft 302 to rotate, so that the air vent 30101 is in communication with the outside, as shown in the figure, and the air pump 201 is controlled to input gas into the second air slot 2005 through the communication pipe 20101, and the gas is blown out of the air vent 30101 to the surface of the arc-shaped protrusion 2001, thereby dissipating heat. At the same time, the motor 303 can be controlled to adjust the angle of the flow guide plate 301 and the shaft 302, so as to adjust the size of the air vent 30101, thereby adjusting the amount of gas passing through. Figure 10

[0049] It should be noted that the flow guide concave surface 30102 is provided on the flow guide plate 301, as shown in the figure. Therefore, part of the gas flowing from the second air slot 2005 to the air vent 30101 will come into contact with the flow guide concave surface 30102. After contacting the flow guide concave surface 30102, the gas is guided to the surface of the arc-shaped protrusion 2001, so that part of the gas flows along the surface of the arc-shaped protrusion 2001, increasing the flowability of the gas on the surface of the arc-shaped protrusion 2001, and increasing the efficiency of the gas in carrying away heat. Figure 10

[0050] Through the arc-shaped groove 2002 at the bottom of the two bottom cabinets 2 and the gap between the support hollow bottom plate 102, the gas enters and is introduced into the air slot 2004 through the connecting pipe 401. Then, the gas is input from the air vent 30101 of the bottom cabinet 2 to the arc-shaped groove 2002 of the upper cabinet 2 by the air pump 201 of the bottom cabinet 2, and the gas is further introduced into the air slot 2004 of the upper cabinet 2 through the connecting pipe 401. In combination with the above-mentioned way of blowing the gas out of the air vent 30101 to the surface of the arc-shaped protrusion 2001 by the air pump 201 through the communication pipe 20101, the air circulation of the air slot 2004 of each cabinet 2 can be performed, the temperature of the air slot 2004 is reduced, and the problem of difficulty in heat dissipation between the cabinets due to the assembly of each cabinet 2 is avoided.

[0051] It should be noted that when the ambient temperature around each cabinet 2 is too high, the cooling effect of the above-mentioned circulating air decreases due to the limited range of air flow. At this time, part of the gas passing through the air slot 2004 can be sprayed out of the air nozzle 402 through the first air slot 2003 and the air nozzle 402, and the gas sprayed out of the air nozzle 402 can accelerate the air flow around each cabinet 2. In combination with the above, the range of circulating air can be further increased, and its efficiency can be increased. Example 3

[0052] ​​Based on the embodiment 2, as shown in Figures 8-9 The ventilation system 103 is communicated with one end of the telescopic air pipe 104, and the other end of the telescopic air pipe 104 is communicated with the supporting hollow bottom plate 102.

[0053] The electric slide rail 101 is further included; the base 1 is installed with two electric slide rails 101 which are symmetrically distributed in front and back, and each electric slide rail 101 is slidably connected with a sliding block, and the two sliding blocks are fixedly connected with the front side and the rear side of the supporting hollow bottom plate 102.

[0054] The working of the present application is as follows:

[0055] When the ambient temperature around the bottom of the bottom cabinet 2 is too high, the temperature of the gas entering the air slot 2004 will also rise, so that the cooling efficiency between the assembled cabinets 2 is reduced, at this time, the part of the cooling gas saved in the inside of the ventilation system 103 due to the coolness can be transported to the inside of the supporting hollow bottom plate 102 from the telescopic air pipe 104 by the fan in the inside of the ventilation system 103, and the air bag 10201 is inflated and contacted with the arc-shaped groove 2002, the cooling gas can cool the surface of the air bag 10201, and the gas passing through the gap between the air bag 10201 and the arc-shaped groove 2002 will contact the surface of the air bag 10201 to be cooled, so as to realize the cooling of the gas entering the air slot 2004, and since there is no direct contact with the humid gas in the inside of the ventilation system 103, the water vapor will not penetrate. It should be noted that the base 1 is installed with two electric slide rails 101 which are symmetrically distributed in front and back, and each electric slide rail 101 is slidably connected with a sliding block, and the two sliding blocks are fixedly connected with the front side and the rear side of the supporting hollow bottom plate 102, the sliding block on the electric slide rail 101 can be controlled to move up and down, and drive the supporting hollow bottom plate 102, the cabinet 2 and the connected parts to move, so that the bottom cabinet 2 is lifted, which is convenient for manual carrying, and the exhaust port 10301 can be shielded to avoid the entry of dust when stopping working.

[0056] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application.
