Description

Technical Field

[0001] This invention belongs to the field of offshore wind power equipment technology, specifically relating to an environmentally friendly gas ring main unit for offshore wind power. Background Technology

[0002] With the profound transformation of the global energy structure, building a new power system based on new energy sources has become a core direction for energy development in various countries. Smart grids, as a key technological support for achieving efficient energy utilization, improving power supply reliability, and promoting large-scale integration of renewable energy, are being rapidly advanced globally. In my country, the proposed "dual-carbon" target has injected strong momentum into smart grid construction. Distribution networks, as an important component of smart grids, are rapidly transforming from the traditional three-in-one model of "master station, communication, and terminal" to a highly automated, intelligent, and interactive system. Ring main units (RNBs), as core switching equipment in distribution networks that realizes power distribution, line segmentation, load transfer, and fault isolation, directly determine the power supply reliability and intelligence level of the distribution network. Offshore wind power, as an important component of new energy power generation in smart grids, places even more stringent requirements on RNBs.

[0003] The various electrical components inside the existing environmentally friendly gas ring main unit for offshore wind power generate a large amount of Joule heat during operation. Since the environmentally friendly gas ring main unit is in a closed state, it is difficult to remove the Joule heat inside the ring main unit. Most existing ring main units use the outer wall of the cabinet to transfer the Joule heat out for heat removal, which has a poor heat removal effect and cannot quickly and effectively help the electrical components to perform heat removal, making the electrical components inside the cabinet prone to failure. Summary of the Invention

[0004] This invention provides an environmentally friendly gas ring main unit for offshore wind power, which aims to solve the problem that most existing environmentally friendly gas ring main units for offshore wind power rely on the outer wall of the cabinet to transfer Joule heat for heat removal, resulting in poor heat removal effect and difficulty in quickly and effectively helping electrical components to perform heat removal, leading to easy failure of electrical components inside the cabinet.

[0005] This invention provides an environmentally friendly gas ring main unit for offshore wind power, comprising a support base, an outer cover fixedly connected to the upper end of the support base, and a pair of doors rotated onto the opening of the outer cover.

[0006] The lower end of the inner part of the outer cover is fixed to the cabinet, and heat removal units are installed on both sides of the cabinet, with one side of the heat removal unit extending outside the outer cover;

[0007] The upper part of the cabinet is equipped with a linkage unit. The two sides of the linkage unit extend to the inner walls of the outer cover and connect with the heat removal unit to pull the heat removal unit to move.

[0008] The heat transfer unit is installed in the outer cover. One side of the heat transfer unit extends into the cabinet and connects with the inner wall of the cabinet to assist the heat removal unit in removing heat.

[0009] A blower unit is installed in the support base, and the blower unit extends to both sides of the support base to blow air to cool the heat removal unit;

[0010] The heat removal unit includes a heat transfer block fixed to one side of the cabinet. Several heat transfer plates are evenly fixed to the outward-facing side of the heat transfer block. One side of the heat transfer plate extends through the side wall of the cabinet into the outer cover. A heat transfer cover is movably installed on the heat transfer plate. One side of the heat transfer cover extends through the side wall of the outer cover to the outside.

[0011] The linkage unit drives the heat transfer plate to open outward or retract inward. The heat transfer block absorbs Joule heat from the cabinet and transfers it to the heat transfer cover through the heat transfer plate. The heat transfer cover then comes into contact with the external airflow to achieve rapid heat removal.

[0012] The linkage unit includes an activation unit fixed to one side of the upper part of the cabinet. A pair of activation boxes are fixed to the upper part of the cabinet. The activation boxes are filled with refrigerant. One side of the activation box is connected to channel one. One side of channel one extends into the cabinet and is connected to a pair of adjustment units. The adjustment units are mounted on the inner wall of one side of the outer cover, and one side extends out of the outer cover and is connected to the heat transfer cover.

[0013] A movable block is installed in the engine box, and the side wall of the movable block is in close contact with the inner wall of the engine box. One side of the movable block is fixedly connected to a linkage rod, and one side of the linkage rod extends through the inner wall of the other side of the engine box into the outer cover and connects with the engine unit.

[0014] The starting unit pulls a pair of linkage rods to move in opposite directions, causing the moving block to move in the starting box, and presses the refrigerant through the channel to the adjustment unit, so that the starting unit can extend and pull the heat transfer shroud to expand.

[0015] The heat transfer unit includes a heat transfer seat fixed to the other side of the heat transfer block. Several heat transfer channels are evenly arranged on one side of the heat transfer seat facing the inside of the cabinet. A reciprocating transfer part is installed in the outer cover. One side of the reciprocating transfer part extends into the cabinet and connects with the upper and lower ends of several heat transfer channels. The upper end extends to the cabinet and connects with the inner walls on both sides of the starter box.

[0016] The refrigerant in the starter box is distributed to several heat transfer channels through a reciprocating conveyor. After absorbing Joule heat, the heat transfer channels transfer the Joule heat to the refrigerant. The reciprocating movement of the refrigerant removes the Joule heat, assisting the heat transfer blocks and heat transfer plates in deheating the cabinet.

[0017] Furthermore, the starting unit includes an electric cylinder fixed to the upper end of the cabinet. A support seat is installed on the movable end of the electric cylinder. A pair of linkage ports are mirror-mounted on the support seat. A pair of connecting parts are mirror-mounted on the upper end of the cabinet. A constraint rod is installed on the connecting part. The lower end of the constraint rod extends into the linkage port and cooperates with the linkage port. One side of the connecting part is connected to one side of the linkage rod.

[0018] The electric cylinder traction support seat moves, and the movement of the connecting part is achieved through the cooperation of the constraint rod and the linkage port. The connecting part pulls the linkage rod to move, so as to achieve the folding or unfolding of the heat transfer cover.

[0019] Furthermore, the connecting part includes a linkage bar screwed to the upper end of the cabinet, a constraint rod fixed to one side of the lower end of the linkage bar, a pin rod fixed to one side of the upper end of the linkage bar, a square shell fixed to one side of the linkage bar, and the upper end of the pin rod extending into the square shell and linked with the square shell.

[0020] When the support seat moves, it presses the constraint rod, causing the linkage bar to rotate and the traction pin to move in an arch shape. The pin, through cooperation with the square shell, transforms the arch shape movement into a horizontal linear movement of the linkage bar. The traction block moves horizontally in the starting box, achieving the purpose of transferring the refrigerant.

[0021] Furthermore, one side of the linkage cylinder is connected to the connecting end three, and one side of the connecting end three extends into the channel one and is fixedly connected to the inner wall of one side of the channel one.

[0022] A silicone platform is movably installed in the linkage cylinder, and the periphery of the silicone platform is in close contact with the inner periphery of the linkage cylinder. A linkage column is installed on one side of the silicone platform. One side of each linkage column passes through the inner wall of the other side of the linkage cylinder and the inner wall of one side of the outer cover and extends to the outside of the outer cover. One side of a pair of linkage columns is fixedly connected to a connecting strip, and the connecting strip is fixedly connected to several heat transfer covers.

[0023] The refrigerant flows into the linkage cylinder through the connecting end, presses the silicone platform to move and pulls the linkage column to move outward of the outer cover, and pulls the heat transfer cover to expand outward through the connecting strip.

[0024] Furthermore, the reciprocating transfer unit includes a second channel that passes through the inner wall of one side of the engine box and is fixedly connected to the engine box. A pump body is fixedly connected to the inner wall of one side of the outer cover. The pump body's suction end is connected to the lower end of the second channel, and the discharge end is connected to the third channel. The lower end of the third channel extends into the cabinet.

[0025] The upper and lower ends of the heat transfer channel are respectively fixedly connected to connecting end one and connecting end two. The lower ends of several connecting ends two extend into channel three and are fixedly connected to the inner wall of channel three. The upper ends of several connecting ends one are fixedly connected to the same channel four. The upper end of channel four extends through the inner wall of the upper end of the cabinet into the starter box and is fixedly connected to the starter box.

[0026] The pump body draws the refrigerant from the starter box through channel two and distributes it to several heat transfer channels through channel three. The refrigerant absorbs Joule heat and returns to the starter box through connection one and channel four, achieving the purpose of continuous heat removal.

[0027] Furthermore, a power switch is installed in passage 1, a power switch is installed in passage 2, and a power switch is installed in passage 4;

[0028] When the heat transfer cover extends outwards, switch one is turned on and switches two and three are closed, allowing the refrigerant to flow into channel one. After the heat transfer cover has finished extending, switch one is closed and switches two and three are turned on, allowing the refrigerant to move in the starter box, channel two, and channel four, thus achieving the purpose of reciprocating heat removal from the heat transfer channels.

[0029] Furthermore, the blowing unit includes a compressor fixed in the support base. The air inlet of the compressor extends outside the support base, and the exhaust of the compressor is connected to channel five. Both sides of the support base are connected to the discharge slots. Both sides of channel five extend into the corresponding discharge slots and are fixed to the inner wall of the discharge slots. The opening of the discharge slot is facing upward and is located at the bottom of several heat transfer shrouds. Baffles are evenly fixed inside the discharge slots, and a dustproof net is also fixed at the top of the baffles.

[0030] The compressor pressurizes the external cold air and transfers it to channel five. Through channel five, the air is distributed to a pair of discharge slots and, with the help of the baffles, is evenly discharged upwards, blowing air onto the heat transfer hood and accelerating the air on the side of the heat transfer hood to dissipate the generated Joule heat.

[0031] The beneficial effects of this invention are as follows:

[0032] By installing a heat removal unit, the heat transfer block (16) can remove the Joule heat generated during the operation of the ring main unit. The heat can then be distributed on several heat transfer plates (19). Before the ring main unit starts working, the heat transfer cover (110) can be moved outward from the outer cover (13) using the linkage unit, expanding the contact range between the heat transfer cover (110) and the external airflow. This can enhance the heat removal function and speed of the heat transfer cover (110). Therefore, the Joule heat transferred to the heat transfer plate (19) can be transferred to the corresponding heat transfer cover (110). The heat transfer cover (110) is fully extended, and the Joule heat transferred to the heat transfer cover (110) can be quickly removed. This allows for stable heat removal of the ring main unit during operation.

[0033] By installing the linkage unit, the action of the starting unit can pull a pair of linkage rods (118) to move towards opposite sides. At this time, the moving block (117) can move in the starting box (111), and the refrigerant hydraulic pressure in the starting box (111) can be sent to the corresponding channel (112). Then it can be distributed to a pair of adjustment units to allow the adjustment units to perform extension activities. Then, several heat transfer covers (110) can be pulled to move out of the outer cover (13). Then, several heat transfer covers (110) can be extended to expand the contact range between the heat transfer covers (110) and the external airflow.

[0034] With the installation of the heat transfer unit, the refrigerant in the starter box (111) can be distributed to several heat transfer channels (18) through the reciprocating transfer section, so that several heat transfer channels (18) are filled with refrigerant. Therefore, when the heat transfer block (16) absorbs Joule heat, several heat transfer channels (18) can also absorb Joule heat. After absorbing Joule heat, the heat transfer channels (18) can transfer Joule heat to the refrigerant. The refrigerant maintains reciprocating flow, and then the Joule heat transferred to the refrigerant can dissipate. Therefore, it can assist several heat transfer plates (19) and several heat transfer covers (110) in performing heat removal on the ring main unit.

[0035] By installing the air blowing unit, after the heat transfer hoods (110) are extended outward, and the Joule heat is sent outward through the heat transfer hoods (110), the external air is pressurized and transferred to the channel five (135) by the pressurizer (134). Since the channel five (135) is distributed in a pair of discharge slots (136), and then under the distribution of several baffles (138), the airflow can be evenly blown upward from the discharge slots (136) to blow on the heat transfer hoods (110), thereby driving the movement speed of the gas on the side of the heat transfer hoods (110), thereby achieving the purpose of blowing air to remove heat from the heat transfer hoods (110), so that the heat transfer hoods (110) can always absorb Joule heat.

[0036] The heat removal range is expanded by the extended heat transfer hood (110), the Joule heat is removed by the reciprocating movement of the refrigerant, and the gas is accelerated by the compressor (134) to achieve rapid heat removal and ensure the working cycle of the internal components of the ring main unit.

[0052] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0053] like Figures 1-12 As shown in the figure, an embodiment of the present invention proposes an environmentally friendly gas ring main unit for offshore wind power, which includes a support base 10, an outer cover 13 fixedly connected to the upper end of the support base 10, and a pair of cover doors 14 mirror-screwed to the opening of the outer cover 13.

[0054] like Figures 4-7 As described, the lower end of the interior of the outer cover 13 is fixedly connected to the cabinet 15, which is used to assemble electrical components. Heat dissipation units are installed on both sides of the cabinet 15, each including a heat transfer block 16, heat transfer plates 19, and a heat transfer cover 110. A heat transfer block 16 is fixedly connected to one side of the cabinet 15, and several heat transfer plates 19 are evenly fixed to the outward-facing surface of the heat transfer block 16. The heat transfer plates 19 extend through the sidewall of the cabinet 15 into the outer cover 13. A heat transfer cover 110 is movably mounted on one side of the heat transfer plates 19 within the outer cover 13, and one side of the heat transfer cover 110 extends through the sidewall of the outer cover 13 to the outside. The heat transfer block 16 absorbs the Joule heat generated by the operation of the electrical components in the cabinet 15 and distributes it to several heat transfer plates 19. The heat transfer cover 110 is driven by the linkage unit to open outward or retract inward along the heat transfer plates 19. When it opens, it increases the contact range with the external airflow, thereby enhancing the heat removal function and speed.

[0055] like Figure 3 and Figure 4 As shown, a temperature sensor 11 is installed at the lower end of the cabinet 15. The temperature sensor 11 is used to monitor the air temperature inside the cabinet 15. A controller 12 is installed at the upper end of the cabinet 15. The controller 12 is used to control the orderly operation of the device.

[0056] like Figure 8 As shown, the linkage unit is installed at the upper end of the cabinet 15. The linkage unit includes an activation unit, an activation box 111, a channel 112, and an adjustment unit. The activation unit includes an electric cylinder 122, a support base 123, and a connecting part. The electric cylinder 122 is fixedly connected to the upper end of the cabinet 15. The support base 123 is installed on the movable end of the electric cylinder 122, and a pair of linkage ports are mirror-mounted on the support base 123. The connecting part includes a linkage bar 120 screwed to the upper end of the cabinet 15. One side of the lower end of the linkage bar 120 is fixedly connected to a constraint rod 124, and the upper end extends into the linkage port for linkage. One side of the upper end is fixedly connected to a pin 121. One side of the linkage bar 118 is fitted with a square shell 119. The upper end of the pin 121 extends into the square shell 119 for linkage. The other side extends through the side wall of the activation box 111 into the outer cover 13. The starter box 111 is mirror-fixed to the upper end of the cabinet 15, filled with refrigerant, and has a fixed channel 112 running through it. An electric switch 132 is fixedly connected to channel 112. A movable block 117 is movably mounted in the starter box 111, with its sidewall in close contact with the inner wall of the starter box 111. One side of the movable block 117 is connected to one side of the linkage rod 118. The adjustment unit includes a pair of linkage cylinders 113 mirror-fixed to the inner surface of one side of the outer cover 13. One side of the linkage cylinders 113 is connected to a connecting end 131, and one side of the connecting end 131 extends into channel 112. A silicone platform 116 is movably mounted in the linkage cylinder 113, with its circumferential surface in close contact with the inner circumferential surface of the linkage cylinder 113. A linkage column 114 is mounted on one side of the silicone platform 116, and one side of the linkage column 114 extends outward through the side wall of the linkage cylinder 113 and the outer cover 13. A connecting strip 115 is fixedly connected to one side of a pair of linkage columns 114, and the connecting strip 115 is fixedly connected to several heat transfer covers 110. When the electric cylinder 122 is activated, the traction support seat 123 moves, driving the constraint rod 124 to rotate the linkage bar 120. The traction pin 121 moves in an arch shape, and through the square shell 119, it becomes a linkage rod 118 that moves horizontally and linearly, driving the moving block 117 to move in the starting box 111, transferring the refrigerant to the channel 112, and flowing into the linkage cylinder 113 through the connecting end 131. This causes the silicone platform 116 and the linkage column 114 to move, allowing the heat transfer covers 110 to be retracted or extended.

[0057] like Figure 6 and Figure 7As shown, a heat transfer unit is installed on the heat removal unit. The heat transfer unit includes a heat transfer base 17, a heat transfer channel 18, and a reciprocating conveyor. The other side of the heat transfer block 16 is fixedly connected to the heat transfer base 17, and several heat transfer channels 18 are evenly arranged on one side facing the interior of the cabinet 15. The reciprocating conveyor includes channel two 125, pump body 126, channel three 127, connecting end one 128, connecting end two 129, and channel four 130. Channel two 125 passes through the side wall of the starter box 111 and is fixedly connected to each other, and an electric switch two 140 is installed inside. The pump body 126 is fixedly connected to the inner wall of one side of the outer cover 13, with the liquid suction end connected to channel two 125 and the liquid discharge end connected to channel three 127. The upper and lower ends of heat transfer channels 18 are respectively fixedly connected to connecting end 128 and connecting end 2 129. The lower ends of several connecting ends 2 129 extend into channel 3 127 and are fixedly connected to each other. The upper ends of several connecting ends 128 are connected to channel 4 130. The upper end of channel 4 130 extends through the upper end of cabinet 15 into starter box 111 and is fixedly connected to each other. Electric switch 3 141 is installed inside. When pump body 126 is activated, it draws the refrigerant in starter box 111 through channel 2 125, distributes it through channel 3 127 into several heat transfer channels 18, and then returns it to starter box 111 through connecting end 128 and channel 4 130, achieving repeated use of refrigerant and dissipating the Joule heat absorbed by heat transfer channels 18.

[0058] like Figure 10 and Figure 11 As shown, a blower unit is installed in the support 10. The blower unit includes a compressor 134, a channel 135, and a discharge trough 136. The compressor 134 is fixed in the support 10, with its air inlet extending outside the support 10 and its exhaust connected to the channel 135. The two sides of the support 10 are connected to the discharge trough 136, and the two sides of the channel 135 extend into the discharge trough 136 and are fixed to each other. The opening of the discharge trough 136 faces upward and is located at the bottom of several heat transfer covers 110. Baffle plates 138 are evenly fixed inside the discharge trough 136, and a dustproof net 137 is also fixed to the top of the baffle plates 138. When the compressor 134 is activated, it pressurizes the outside air and transfers it to the fifth channel 135, where it is distributed into a pair of discharge slots 136. After being dispersed by the baffle plate 138, the air is evenly discharged upwards and expelled onto the heat transfer cover 110, which increases the speed of the air movement on the side of the heat transfer cover 110 and dissipates the generated Joule heat.

[0059] When the electrical components in cabinet 15 are operating, the heat transfer block 16 absorbs the generated Joule heat. The electric cylinder 122 actuates, causing the heat transfer cover 110 to expand via a linkage unit, increasing the heat removal range. Simultaneously, the pump 126 actuates, causing the refrigerant to reciprocate within the heat transfer channel 18, assisting in heat removal. The compressor 134 actuates, blowing air onto the heat transfer cover 110 to further enhance the heat removal function and speed, ensuring the stable operation of the ring main unit. After heat removal is complete, the heat transfer cover 110 retracts via the linkage unit to prevent the exposure and accumulation of dust.

[0060] It should also be noted that temperature sensor 11, electric cylinder 122, pump body 126, electric switch one 132, pressurizer 134, electric switch two 140, and electric switch three 141 are all electrically connected to controller 12. When temperature sensor 11 detects that the air temperature in cabinet 15 is high, it transmits the signal to controller 12. Controller 12 controls the relevant equipment to operate in an orderly manner, which not only saves energy and is environmentally friendly, but also removes heat from the ring main unit in a timely manner. Temperature sensor 11, electric cylinder 122, pump body 126, electric switch one 132, cabinet 15, pressurizer 134, electric switch two 140, electric switch three 141, and controller 12 are all existing equipment and will not be described in detail here.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.

Several heat transfer channels are evenly arranged on one side of the heat transfer seat facing the inside of the cabinet. A reciprocating transfer part is installed in the outer cover. One side of the reciprocating transfer part extends into the cabinet and connects with the upper and lower ends of several heat transfer channels. The upper end extends to the cabinet and connects with the inner walls on both sides of the starter box. The refrigerant in the starter box is distributed to several heat transfer channels through a reciprocating conveyor. After absorbing Joule heat, the heat transfer channels transfer the Joule heat to the refrigerant. The reciprocating movement of the refrigerant removes the Joule heat, assisting the heat transfer blocks and heat transfer plates in deheating the cabinet.

When the support seat moves, it presses the constraint rod, causing the linkage bar to rotate and the traction pin to move in an arch shape. The pin, through cooperation with the square shell, transforms the arch shape movement into a horizontal linear movement of the linkage bar. The traction block moves horizontally in the starting box, achieving the purpose of transferring the refrigerant.

4. The environmentally friendly gas ring main unit for offshore wind power according to claim 1, characterized in that: One side of the linkage cylinder is connected to the connecting end three, and one side of the connecting end three extends into the channel one and is fixedly connected to the inner wall of one side of the channel one.

The upper and lower ends of the heat transfer channel are respectively fixedly connected to connecting end one and connecting end two. The lower ends of several connecting ends two extend into channel three and are fixedly connected to the inner wall of channel three. The upper ends of several connecting ends one are fixedly connected to the same channel four. The upper end of channel four extends through the inner wall of the upper end of the cabinet into the starter box and is fixedly connected to the starter box. The pump body draws the refrigerant from the starter box through channel two and distributes it to several heat transfer channels through channel three. The refrigerant absorbs Joule heat and returns to the starter box through connection one and channel four, achieving the purpose of continuous heat removal.

6. The environmentally friendly gas ring main unit for offshore wind power according to claim 5, characterized in that: A power switch is installed in passage 1, a power switch is installed in passage 2, and a power switch is installed in passage 4. When the heat transfer cover extends outwards, switch one is turned on and switches two and three are closed, allowing the refrigerant to flow into channel one. After the heat transfer cover has finished extending, switch one is closed and switches two and three are turned on, allowing the refrigerant to move in the starter box, channel two, and channel four, thus achieving the purpose of reciprocating heat removal from the heat transfer channels.
