Description

Technical Field

[0001] The invention belongs to the technical field of power output equipment, and in particular relates to an intelligent temperature-controlled ring network cabinet anti-condensation protection device. Background Art

[0002] Ring main units usually need to work in complex environments. The temperature, humidity and weather conditions of the external air can easily affect the operation of the ring main unit. Especially when the humidity is high, it is easy for horizontal air to enter and condense after being cooled, thus causing damage to the internal electrical components. Therefore, the outside of the ring main unit needs to be protected.

[0003] After searching, the cited announcement number is CN118174182B, and the announcement date is August 13, 2024. The patent document is called "A patent document of an environmentally friendly gas-insulated fully sealed ring network cabinet with good sealing performance", which includes a cabinet body, and the cabinet body is provided with a control chamber, a sealing chamber, a power chamber, and a heat exchange chamber from top to bottom. The sealing chamber is equipped with a sealing box, and the front side of the sealing box is equipped with a sealing component. It also includes a self-adjusting assembly frame, a heat exchange component, a heat dissipation network, and an air supply component assembled in the cabinet body. The self-adjusting assembly frame is arranged in the sealing box, and the self-adjusting assembly frame includes multiple layers of height-adjustable assembly frame plates. The heat exchange component includes an air collecting hood assembled on the top of the sealing box and an air distribution plate assembled on the bottom of the sealing box. The heat dissipation network is arranged in the heat exchange chamber. The air collecting hood is equipped with a hot air pipe connected to the inlet end of the heat dissipation network, and the air distribution plate is equipped with a cold air pipe connected to the outlet end of the heat dissipation network. In the above embodiment, the driving fans installed on both sides of the heat exchange chamber are operated in both directions, so that cold air from the outside can enter the heat exchange chamber from different directions. The cold air can efficiently dissipate heat from the heat dissipation pipe network to ensure efficient heat dissipation of each device in the sealed box and improve the stable operation performance of the equipment.

[0004] However, the above embodiment still has the following defects:

[0005] It is unable to remove moisture from the air, and it is also unable to switch modes according to the actual environment. When the external weather is extremely changeable, such as heavy rain, rainwater will enter the cabinet in a short period of time, making it impossible to achieve anti-condensation and automation effects. At the same time, the non-stop operation of the driving fan increases energy consumption. Summary of the invention

[0008] Under normal circumstances, air enters the adjusting roller through the air intake mechanism, and the moisture in the air is filtered by the condensation component, and then the air exchange is achieved using the internal ventilation component. Under extreme conditions, the adjusting roller rotates to make the active ventilation component face outward, stopping the ventilation work and realizing self-regulating intelligent temperature and humidity control.

[0011] Furthermore, the output end of the gas collecting pipe is connected to a second ventilation pipe, and the second ventilation pipe is provided with an electric ball valve.

[0012] Furthermore, a rotating mechanism is provided on the top of the adjustment plate; the rotating mechanism includes a top box, in which a number of groups of transmission gears are arranged at equal intervals in the horizontal direction with the same number of rotation slots, and the input end of each group of the anti-condensation units extends into the top box and is transmission-connected to a corresponding group of transmission gears; chains are transmission-connected between the groups of transmission gears; a servo motor is transmission-connected to the input end of one group of the transmission gears.

[0013] Furthermore, the condensation component includes an outer baffle tube, which is concentrically arranged in the adjusting roller cavity, and a plurality of drainage grooves are distributed in a circular array on the outer wall of the outer baffle tube. The drainage grooves are inclined, and the depth of the bottom is greater than the depth of the top, and the bottom of the drainage groove is an open structure.

[0014] Furthermore, a spiral condenser is installed on the inner wall of the outer baffle tube; the spiral condenser is a spiral structure, the input end of the spiral condenser extends to the outside of the adjusting roller, and is provided with a condensate inlet; a one-way valve is provided at the bottom of the adjusting roller.

[0015] Furthermore, the movable ventilation component includes a crescent plate, and a plurality of groups of dry gas outlet pipes are arranged at equal intervals on the upper side of the crescent plate in the vertical direction, and the output end of the dry gas outlet pipe is movably fitted with a corresponding group of first ventilation pipes; a horizontal sliding groove is opened on the output end of the dry gas outlet pipe in the horizontal direction, and a sealing block is slidably connected to the horizontal sliding groove, and the sealing block is movably in contact with the output end of the dry gas outlet pipe.

[0016] Furthermore, a connecting block is installed on a side wall of the sealing block away from the anti-detachment block, and a transverse plate is installed on the connecting block. One end of an elastic component is provided on the transverse plate, and the other end of the elastic component is installed on the outer wall of the dry gas outlet pipe; the output end of the dry gas outlet pipe is movably in contact with the input end of a corresponding group of first ventilation pipes, and the side wall of the dry gas outlet pipe is movably fitted with the side baffle.

[0017] Furthermore, the air intake mechanism includes an air intake block, an air inlet is provided on a side wall of the air intake block away from the adjusting roller, a plurality of groups of baffles are arranged at equal intervals in the vertical direction on the input end of the air inlet, the baffles are inclined, and the height of one end close to the entrance of the air inlet is lower than the height of the other end; an air outlet pipe is connected to the output end of the air inlet, and the output end of the air outlet pipe extends into the cavity of the adjusting roller.

[0018] The beneficial effects of the present invention are:

[0019] 1. When the air humidity and temperature are normal, the air enters the adjusting roller through the air intake mechanism, and then after being dehumidified by the condensing component, the dry air is transported to the cabinet protective shell, which not only realizes the heat exchange of the internal components but also prevents the entry of water vapor, thus achieving the anti-condensation effect. When the air humidity is high or the temperature is high, the adjusting roller automatically rotates so that one side of the movable ventilation component faces outward, thereby cutting off the outside air from entering the cabinet protective shell, and then heat is dissipated through the external heat exchange equipment. Through these two modes, the anti-condensation effect is achieved while dissipating heat, and the device can adjust itself according to the actual environmental temperature and humidity, meeting the function of intelligent temperature and humidity control, which not only improves the anti-condensation effect and automation of the device, but also reduces energy consumption.

[0020] 2. After the air enters the adjusting roller, it contacts the outer baffle tube, and the outer baffle tube is cooled by the spiral condenser tube. Because the spiral condenser tube is distributed along a spiral path, no matter from which angle and height the air contacts the outer baffle tube, the moisture contained in it can quickly condense when it is cooled, thereby accelerating the dehumidification speed. The bottom depth of the drainage groove is greater than the top, which allows the condensed water droplets to be completely gathered and guided, so that all of them can be discharged to avoid moisture remaining in the adjusting roller. At the same time, the inlet of the spiral condenser tube is located outside the adjusting roller, so that the condensate can be added quickly, which not only speeds up the dehumidification speed but also improves the convenience of subsequent maintenance.

[0021] 3. When the dry gas outlet pipe is connected to the first ventilation pipe, the first ventilation pipe will push the anti-detachment block to one side, and under the action of the side baffle, the first ventilation pipe and the dry gas outlet pipe can fit closely to prevent air loss. When one side of the dry gas outlet pipe needs to face the outside, the push of the first ventilation pipe is lost. Under the action of the elastic component, the sealing block quickly resets and completely covers the dry gas outlet pipe, so that the air circulation can be quickly terminated. At the same time, the horizontal sliding groove also ensures the accurate reset of the sealing block. It provides auxiliary effect for the switching of the two modes and also ensures the stability of air circulation and air sealing.

[0022] 4. When the sealed door is closed, it is detected by the distance sensor, which then sends information to the control mechanism of the vacuum pump, which then makes the vacuum pump work and evacuates the cavity of the cabinet protective shell, so that only the dry air generated by the anti-condensation unit enters. When the sealed door needs to be opened, it is only necessary to transport air into the cabinet protective shell through the vacuum pump to balance the pressure difference between the inside and the outside. This reduces the probability of condensation of moisture in the internal air.

[0023] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The embodiment of the present invention provides an intelligent temperature-controlled ring main unit anti-condensation protection device. For example, Figure 1 and Figure 2 As shown, it includes a cabinet protective shell 100, an exhaust pipe 110 is provided on the cabinet protective shell 100, and a vacuum pump is provided on the input end of the exhaust pipe 110. A sealing door 120 is provided on the outer wall of one side of the cabinet protective shell 100, and a distance sensor is provided at the junction of the sealing door 120 and the cabinet protective shell 100, and the distance sensor is electrically connected to the control mechanism of the vacuum pump. A heat exchange device is provided on one side of the cabinet protective shell 100, and the output end of the heat exchange device extends into the cabinet protective shell 100.

[0043] When the sealed door 120 is closed, it is detected by the distance sensor, and then information is sent to the control mechanism of the vacuum pump, which then causes the vacuum pump to work and evacuate the cavity of the cabinet protective shell 100, so that only dry air generated by the anti-condensation unit 300 enters. When the sealed door 120 needs to be opened, air is simply delivered into the cabinet protective shell 100 through the vacuum pump to balance the pressure difference between the inside and the outside.

[0044] A group of adjustment units 200 are provided on each group of side walls of the cabinet protective housing 100 and the sealing door 120. A plurality of groups of anti-condensation units 300 are arranged at equal intervals in the horizontal direction on the adjustment unit 200, and the anti-condensation units 300 are rotatably connected to the output end of the adjustment unit 200. The adjustment unit 200 drives each group of anti-condensation units 300 to rotate to cope with different environments.

[0045] For example, Figure 3 , Figure 4 and Figure 5 As shown, the adjustment unit 200 includes an adjustment plate 210, and a side wall of the adjustment plate 210 away from the inner cavity of the cabinet protective shell 100 is arranged with a plurality of groups of rotating grooves 211 at equal intervals in the horizontal direction, and each group of the anti-condensation unit 300 is rotatably connected in a corresponding group of rotating grooves 211. The top view of the rotating groove 211 is a fan-shaped structure. On the inner wall of the rotating groove 211, a plurality of groups of air pipe chute 212 are arranged at equal intervals in the vertical direction, and one end of the air pipe chute 212 is an open structure. A humidity monitoring component is installed on the outer wall of the adjustment plate 210.

[0046] Exemplarily, a plurality of groups of air collecting pipes 240 are arranged at equal intervals in the horizontal direction on a side wall of the adjustment plate 210 close to the cabinet protective shell 100, and the number of the air collecting pipes 240 is the same as the number of the rotating slots 211. A ventilation cavity 220 is provided inside the adjustment plate 210, and a plurality of groups of first air exchange pipes 230 are provided in the ventilation cavity 220, and the number of the first air exchange pipes 230 is the same as the number of the air pipe chute 212, and the input end of each group of the first air exchange pipes 230 corresponds to the end of the corresponding group of air pipe chute 212 away from the opening. The output ends of the plurality of groups of the first air exchange pipes 230 on the same vertical line are all connected to the corresponding group of air collecting pipes 240. A side baffle 231 is installed on the input end of the first air exchange pipe 230.

[0047] Specifically, the output end of the gas collecting pipe 240 is connected to a second ventilation pipe 250 , and the second ventilation pipe 250 is provided with an electric ball valve 260 .

[0048] The first ventilation pipe 230 , the second ventilation pipe 250 , the electric ball valve 260 and the air collecting pipe 240 together constitute an inner ventilation component.

[0049] Specifically, a rotating mechanism 270 is disposed on the top of the adjustment plate 210 .

[0050] For example, Figure 6 As shown, the rotating mechanism 270 includes a top box 271, in which a number of groups of transmission gears 272 are arranged in the top box 271 at equal intervals in the horizontal direction, and the number of the same number as the rotating slots 211, and the input end of each group of the anti-condensation unit 300 extends into the top box 271 and is transmission-connected to a corresponding group of transmission gears 272. Chains 273 are transmission-connected between the groups of transmission gears 272. A servo motor 274 is transmission-connected to the input end of one group of the transmission gears 272.

[0051] When the ambient humidity is normal, the heat exchange device stops working, the anti-condensation unit 300 circulates with the outside air, and after dehumidification, the dry air is transported to each group of first ventilation pipes 230, and then transported to the cabinet protective shell 100 through each group of air collecting pipes 240 and second ventilation pipes 250, so as to realize the heat exchange of natural air, which can not only prevent the moisture in the outside air from entering the cabinet protective shell 100, but also reduce energy consumption. When encountering extreme weather such as heavy rain, the humidity monitoring component detects that the humidity in the air is too high. At this time, the humidity monitoring component sends a signal to the rotating mechanism 270, and the servo motor 274 starts to work to drive each group of transmission gears 272 to rotate, and makes each group of anti-condensation units 300 rotate, thereby disconnecting the anti-condensation unit 300 and each group of first ventilation pipes 230, so that the outside air no longer enters the cabinet protective shell 100, and at the same time, the heat exchange device is turned on to realize the heat exchange function of each component of the ring network cabinet through heat exchange.

[0052] For example, Figure 7 , Figure 8 and Fig. 9 As shown, the anti-condensation unit 300 includes a rotating rod 310, which is rotatably connected in a corresponding group of rotating grooves 211, and the top is transmission-connected to a corresponding group of transmission gears 272. An adjusting roller 320 is sleeved on the outside of the rotating rod 310, and a plurality of groups of air intake mechanisms 330 are evenly distributed on the outer wall of the adjusting roller 320 away from the inner cavity of the rotating groove 211. An outer blocking tube 340 is concentrically arranged inside the adjusting roller 320.

[0053] Exemplarily, a plurality of drainage grooves 341 are distributed in a circular array on the outer wall of the outer baffle tube 340. The drainage grooves 341 are inclined, and the depth of the bottom is greater than the depth of the top. The bottom of the drainage grooves 341 is an open structure. A spiral condenser tube 350 is installed on the inner wall of the outer baffle tube 340. The spiral condenser tube 350 is a spiral structure. The input end of the spiral condenser tube 350 extends to the outside of the adjusting roller 320 and is provided with a condensate inlet. A one-way valve is provided at the bottom of the adjusting roller 320.

[0054] Specifically, the outer baffle tube 340, the drainage groove 341 and the spiral condenser tube 350 are combined to form a condensation component.

[0055] For example, Fig.10 , Fig.11 and Fig.12As shown, a crescent plate 360 ​​is installed on one side wall of the adjusting roller 320 near the inner cavity of the rotating groove 211, and the cross section of the crescent plate 360 ​​is a fan-shaped structure when viewed from above. A plurality of groups of dry gas outlet pipes 361 with the same number as the tracheal chute 212 are arranged at equal intervals in the vertical direction on the crescent plate 360, and the dry gas outlet pipes 361 are slidably connected in a corresponding group of tracheal chute 212. A horizontal slide groove 362 is provided in the horizontal direction on the output end of the dry gas outlet pipe 361, and an anti-slip block 363 is provided at one side edge of the horizontal slide groove 362, and a sealing block 370 is slidably connected to the horizontal slide groove 362, and the sealing block 370 is movably in contact with the output end of the dry gas outlet pipe 361.

[0056] Exemplarily, a connection block 371 is installed on one side wall of the sealing block 370 away from the anti-slip block 363, a transverse plate 372 is installed on the connection block 371, one end of an elastic component 373 is provided on the transverse plate 372, and the other end of the elastic component 373 is installed on the outer wall of the dry gas outlet pipe 361. The output end of the dry gas outlet pipe 361 flexibly contacts the input end of a corresponding group of first ventilation pipes 230, and the side wall of the dry gas outlet pipe 361 flexibly fits with the side baffle 231.

[0057] Specifically, the crescent plate 360, the dry gas outlet pipe 361, the transverse slide groove 362, the anti-slip block 363, the sealing block 370, the connecting block 371, the transverse plate 372 and the elastic component 373 are combined to form a movable ventilation component.

[0058] For example, Fig.13 and Fig.14 As shown, the air intake mechanism 330 includes an air intake block 331, and an air intake port 332 is provided on a side wall of the air intake block 331 away from the adjusting roller 320. A plurality of baffles 333 are arranged at equal intervals in the vertical direction on the input end of the air intake port 332. The baffles 333 are inclined, and the height of one end close to the entrance of the air intake port 332 is lower than the height of the other end. The output end of the air intake port 332 is connected to an air outlet pipe 334, and the output end of the air outlet pipe 334 extends into the cavity of the adjusting roller 320.

[0059] When the ambient humidity is normal, the side of the adjusting roller 320 close to the air intake mechanism 330 faces the outside, and the air passes through the gaps between the baffles 333 into the air inlet 332, and then enters the cavity of the adjusting roller 320 through the air outlet pipe 334. At this time, due to the condensate added to the spiral condenser 350, the temperature of the outer baffle 340 drops. After the air contacts the outer wall of the outer baffle 340, the moisture contained in the air condenses when it is cold, and all is collected in the one-way valve below along the drainage groove 341 and discharged. The dry air that has lost moisture enters the first ventilation pipe 230 through the dry gas outlet pipe 361, and finally enters the ring network cabinet. While ensuring heat exchange, it also prevents moisture from entering the ring network cabinet, avoiding condensation.

[0060] For example, Fig.15 As shown, when the humidity in the air is too high, the adjusting roller 320 is driven to rotate by the rotating mechanism 270, so that the dry gas outlet pipe 361 is separated from the first ventilation pipe 230. At the same time, under the action of the elastic component 373, the sealing block 370 is reset and re-covered on the dry gas outlet pipe 361 to block it. Then the dry gas outlet pipe 361 slides along the air pipe slide groove 212 until it is separated from the air pipe slide groove 212 and the side wall of the adjusting roller 320 close to the air intake mechanism 330 is completely located in the rotating groove 211, and then each group of electric ball valves 260 is closed to cut off the air circulation between the regulating unit 200 as a whole and the cabinet protective shell 100, so that the cabinet protective shell 100 is completely in a closed state, and the heat exchange equipment is used to achieve the heat dissipation effect of each component of the internal ring network cabinet.

[0061] The above embodiments have the following beneficial effects:

[0062] 1. When the air humidity is normal, the air enters the adjusting roller 320 through the air intake mechanism 330, and after being dehumidified by the condensing component, the dry air is transported to the cabinet protective shell 100, which prevents water vapor from entering while achieving heat exchange between the internal components, thereby achieving the anti-condensation effect. When the air humidity is high, the adjusting roller 320 automatically rotates so that one side of the movable ventilation component faces outward, thereby cutting off the outside air from entering the cabinet protective shell 100, and then heat is dissipated through the external heat exchange equipment. The two modes achieve both heat dissipation and anti-condensation effects, and allow the device to adjust itself according to the actual environment, which not only improves the anti-condensation effect and automation of the device, but also reduces energy consumption.

[0063] 2. After the air enters the adjusting roller 320, it contacts the outer baffle tube 340, and the outer baffle tube 340 is cooled by the spiral condenser tube 350. Because the spiral condenser tube 350 is distributed along a spiral path, when the air contacts the outer baffle tube 340 from any angle and height, the moisture contained in it can quickly condense when it is cooled, thereby accelerating the dehumidification speed. In addition, the bottom depth of the drainage groove 341 is greater than the top, which allows the condensed water droplets to be completely collected and guided, so that they can all be discharged, avoiding moisture from remaining in the adjusting roller 320. At the same time, the inlet of the spiral condenser tube 350 is located outside the adjusting roller 320, so that the condensate can be quickly added, which not only accelerates the dehumidification speed but also improves the convenience of subsequent maintenance.

[0064] 3. When the dry gas outlet pipe 361 is connected to the first ventilation pipe 230, the first ventilation pipe 230 will push the anti-detachment block 363 to one side, and under the action of the side baffle 231, the first ventilation pipe 230 and the dry gas outlet pipe 361 can fit tightly to prevent air loss. When one side of the dry gas outlet pipe 361 needs to face the outside, the push of the first ventilation pipe 230 is lost. Under the action of the elastic component 373, the sealing block 370 quickly resets and completely covers the dry gas outlet pipe 361, so that the air circulation can be quickly terminated. At the same time, the horizontal sliding groove 362 also ensures the accurate reset of the sealing block 370. It provides an auxiliary effect for the switching of the two modes and also ensures the stability of air circulation and air sealing.

[0065] 4. When the sealed door 120 is closed, it is detected by the distance sensor, and then information is sent to the control mechanism of the vacuum pump, which then makes the vacuum pump work to evacuate the cavity of the cabinet protective shell 100, and only the dry air generated by the anti-condensation unit 300 enters it. When the sealed door 120 needs to be opened, it is only necessary to transport air into the cabinet protective shell 100 through the vacuum pump to balance the pressure difference between the inside and the outside. The probability of condensation of moisture in the internal air is reduced.

[0066] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
