[0002] The superconducting power transmission device is a power transmission device based on superconducting technology. Its main feature is to achieve almost lossless power transmission by using cables made of superconducting materials. The following is a detailed explanation of the superconducting power transmission device: 1. Definition and principle: Superconducting power transmission devices use the property of superconducting materials that their resistance becomes almost zero under specific low temperature conditions (such as liquid nitrogen environment at minus 196 degrees Celsius) to make superconducting cables for power transmission. This technology can significantly reduce the loss of electric energy during transmission.

[0003] 2. Technical features: High efficiency: Since the resistance of superconducting cables is almost zero, the loss of electricity during transmission is extremely low. Compared with traditional cables, the power transmission efficiency of superconducting cables is significantly improved.

[0004] 3. Large capacity: Superconducting cables can transmit strong currents, and their current carrying capacity is equivalent to the sum of multiple ordinary cables with the same voltage level. They are suitable for the "narrow channel and large capacity" transmission needs of large city power grids.

[0005] 4. Environmental protection and energy saving: Superconducting power transmission technology can reduce energy waste, reduce carbon emissions, and help promote green and low-carbon energy transformation.

[0006] 5. Application areas: Urban power grid transformation: Superconducting cables can be used to transform and upgrade urban power grids to improve power transmission efficiency and reliability.

[0007] 6. New energy grid connection: With the large-scale grid connection of new energy such as wind power and photovoltaic power, superconducting cables can be used for the transmission of new energy electricity to meet the needs of long-distance and large-capacity transmission of new energy electricity.

[0008] 7. Large scientific facilities: Superconducting power transmission technology can also be applied to large scientific facilities, such as particle accelerators, maglev trains, etc., to provide stable and efficient power support for these devices.

[0009] 8.Technological progress and prospects: With the advancement of superconducting material technology and the increase in scientific research investment, the performance of superconducting cables has been continuously improved and the scope of application has been gradually expanded. At present, many superconducting cable demonstration projects have been successfully put into operation at home and abroad.

Obviously, the described embodiments are only 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.

[0026] like Figures 1 to 8 As shown, the present invention provides a superconducting power transmission device, comprising a superconducting power transmission device body 1; a connecting support seat 4, which is arranged on the left side of the top of the superconducting power transmission device body 1, and a gas storage tank 3 is arranged on the right side; a superconducting power transmission line pipe 5, which is movably installed on the left side of the connecting support seat 4; a multi-caliber connecting component 6 includes a first-caliber connecting piece 601, the first-caliber connecting piece 601 is movably sleeved on the left side of the inner wall of the connecting support seat 4, the first-caliber connecting piece 601 is movably sleeved with a second-caliber connecting piece 602 inside the first-caliber connecting piece 601, and the second-caliber connecting piece 602 is movably sleeved with a third-caliber connecting piece 603 inside the second-caliber connecting piece 602, and the right sides of the front and rear ends of the first-caliber connecting piece 601, the second-caliber connecting piece 602 and the third-caliber connecting piece 603 are fixedly installed with a return spring 604, the connection support seat 4 is provided with a clamping component 7 located at the top of the left side of the first-caliber connecting piece 601, and the connection support seat 4 is provided with a clamping component 8 on the upper left side.

[0027] When the superconducting transmission line tube 5 is inserted to the right into the connecting support seat 4 and drives the first caliber connecting piece 601 or the second caliber connecting piece 602 or the third caliber connecting piece 603 to the right, it will be pushed to the right side of the bottom of the clamping component 7. At this time, the clamping component 8 can be driven to drive the bottom of the clamping component 7 to move downward, so that the superconducting transmission line tube 5 is fixed as a whole.

[0028] like Figure 5 As shown, the other end of the return spring 604 is fixedly connected to the inner walls of the connecting support seat 4, the first caliber connecting member 601 and the second caliber connecting member 602 respectively.

[0029] The above solution is adopted: by providing a reset spring 604, due to the elastic force of the reset spring 604, when released, it will push the first caliber connecting member 601, the second caliber connecting member 602 and the third caliber connecting member 603 to reset to the left respectively for subsequent installation.

[0031] By adopting the above solution: by providing a driving handle 703, the operator can pull the driving handle 703 to drive the clamping piston rod 702 upward as a whole, so that the bottom of the clamping piston rod 702 is disengaged from the top groove of the superconducting transmission line tube 5, and the fixation of the superconducting transmission line tube 5 can be released.

[0032] like Figure 6 As shown, the other end of the power spring 704 is fixedly connected to the inner wall of the pneumatic groove 701 .

[0033] The above solution is adopted: by providing a power spring 704, when the elastic force of the power spring 704 is released, it will push the clamping piston rod 702 downward as a whole, so that the bottom end of the clamping piston rod 702 is clamped on the top of the superconducting transmission line tube 5, and the superconducting transmission line tube 5 is fixed.

[0034] like Figures 6 to 8 As shown, the clamping assembly 8 includes a clamping block 801, a connecting frame 802, a movable block 803, a linkage arm 804 and a threaded rod 805; The clamping block 801 is movably installed in the grooves at the front and rear sides of the bottom of the clamping piston rod 702, the connecting frame 802 is movably installed inside the connecting support seat 4 and outside the clamping block 801, and the inner bottom is fixedly connected to the outer side of the clamping block 801, the movable block 803 is movably installed inside the connecting support seat 4 and the inner side of the top of the connecting frame 802, the linkage arm 804 is hinged to the outer side of the movable block 803 and the left end of the inner side of the top of the connecting frame 802, the threaded rod 805 is movably sleeved on the left side of the movable block 803, and the surface is threadedly sleeved on the inner wall of the connecting support seat 4.

[0035] The above scheme is adopted: by setting it on the threaded rod 805, when the operator rotates the threaded rod 805, the movable block 803 can be driven to move to the right as a whole, so that the linkage arm 804 is deflected to drive the two connecting frames 802 and the clamping block 801 to move away from each other, and finally the inner end of the clamping block 801 is disengaged from the bottom groove of the clamping piston rod 702, and the clamping fixation of the clamping piston rod 702 can be released.

[0036] like Figure 2 As shown, a sealing assembly 9 located outside the superconducting transmission line tube 5 is provided on the left side of the connecting support seat 4, and the sealing assembly 9 includes a fixing shell 901, a sealing clamp 902 and a fixing strip 903; The fixed shell 901 is movably installed on the left side of the connecting support seat 4 and in front and behind the superconducting transmission line tube 5. The sealing card 902 is arranged between the inner side of the fixed shell 901 and the surface of the superconducting transmission line tube 5. The fixing bar 903 is fixedly installed on the outer side of the bottom of the fixed shell 901.

[0037] The above solution is adopted: by providing the sealing clamp 902, due to the deformability of the sealing clamp 902, it can be adapted and sealed according to the superconducting transmission line pipes 5 of different calibers.

[0038] like Figure 4 As shown, a limiting rod 10 located on the bottom inner wall of the fixed shell 901 is fixedly installed on the left side of the connecting support seat 4.

[0039] With the above solution, due to the design of the limiting rod 10 , the fixed shell 901 and the sealing clamp 902 can be limited in their movement toward or away from each other.

[0040] like Figure 4 As shown, a driving assembly 11 located inside the fixing bar 903 is provided on the left side of the connecting support seat 4, and the driving assembly 11 includes a driving rotating plate 1101, a rotating disk 1102 and a driving shaft 1103; The driving rotating plate 1101 is movably connected to the left side of the connecting support seat 4 and the inner side of the right end of the fixing bar 903, the rotating disk 1102 is movably connected to the middle part of the left side of the driving rotating plate 1101, and the driving shaft 1103 is fixedly installed at the front and rear ends of the driving rotating plate 1101, and the left end extends to the inner wall of the fixing bar 903.

[0041] The above solution is adopted: by providing a driving shaft 1103, when the driving rotating plate 1101 and the rotating disk 1102 are rotated, the left side of the driving shaft 1103 will slide on the inner wall of the fixed bar 903, so as to drive the two fixed bars 903, the fixed shell 901 and the sealing card 902 to move toward or away from each other.

[0042] like Figure 4 As shown, a pneumatic assembly 12 located below the driving rotating plate 1101 is provided on the left side of the connecting support seat 4, and the pneumatic assembly 12 includes a pneumatic cylinder 1201, a pneumatic piston rod 1202, a connecting pipe 1203 and a linkage block 1204; The pneumatic cylinder 1201 is fixedly installed on the left side of the connecting support seat 4 and below the rotating disk 1102, the pneumatic piston rod 1202 is movably installed inside the pneumatic cylinder 1201, the connecting pipe 1203 is fixedly connected between the top of the back side of the pneumatic cylinder 1201 and the bottom of the back side of the pneumatic groove 701, the linkage block 1204 is fixedly installed on the top of the pneumatic piston rod 1202, and the inner wall is movably connected to the left side part of the rotating disk 1102.

[0043] The above scheme is adopted: by providing a pneumatic piston rod 1202, when the clamping piston rod 702 moves downward, the gas in the inner cavity at the bottom of the pneumatic groove 701 can be pushed to be introduced into the bottom of the inner cavity of the pneumatic cylinder 1201 through the connecting pipe 1203, so that the air pressure becomes larger and pushes the pneumatic piston rod 1202 and the linkage block 1204 to move downward, and when the superconducting transmission line tube 5 pushes the second caliber connecting piece 602 or the third caliber connecting piece 603, the clamping piston rod 702 will move deeper downward, thereby making the internal air pressure of the pneumatic cylinder 1201 greater, and the pneumatic piston rod 1202 and the linkage block 1204 move deeper downward, and the deflection angle of the driving rotating plate 1101 and the rotating disk 1102 is larger, and finally the sealing clamp 902 clamps and fits the superconducting transmission line tube 5 with a smaller diameter.

[0044] like Figure 1 As shown, a heat exchange mechanism is applied to a superconducting power transmission device, and a heat exchange mechanism body 2 located on the right end surface of a gas storage tank 3 is arranged on the top of the superconducting power transmission device body 1.

[0045] The working principle and use process of the present invention: First, when the operator needs to install the superconducting transmission line pipe 5 of corresponding caliber at the position of the connecting support seat 4, the superconducting transmission line pipe 5 can be inserted into the connecting support seat 4, and the first caliber connecting piece 601 or the second caliber connecting piece 602 or the third caliber connecting piece 603 can be pushed to the right, so that the pushed movement is to the right side of the bottom of the clamping piston rod 702, and then the threaded rod 805 can be twisted to rotate to the left by hand to drive the movable block 803 to move to the right synchronously, and then the two linkage arms 804 will deflect and push the two connecting frames 802 and the clamping block 801 to move in opposite directions until the inner end of the clamping block 801 is disengaged from the top groove of the clamping piston rod 702, which can release the fixing effect of the clamping piston rod 702, so that the elastic force of the power spring 704 is smoothly released, and finally the clamping piston rod 702 is pushed downward so that the bottom end is inserted into the top groove of the superconducting transmission line pipe 5, and the superconducting transmission line pipe 5 of corresponding caliber is installed and connected with the connecting support seat 4 and the gas storage tank 3.

[0046] At the same time, when the clamping piston rod 702 moves downward, the gas in the inner cavity of the pneumatic groove 701 can be pushed into the inside of the pneumatic cylinder 1201 through the connecting tube 1203, so that the air pressure in the inner cavity at the top of the pneumatic cylinder 1201 increases and pushes the pneumatic piston rod 1202 and the linkage block 1204 to move downward as a whole, thereby smoothly driving the rotating disk 1102 and the driving rotating plate 1101 to rotate, and then making the driving shaft 1103 slide along the inner wall of the fixed bar 903 to drive the two fixed bars 903, the fixed shell 901 and the sealing clamp 902 to move towards each other, and finally making the inner side of the sealing clamp 902 fit tightly against the surface of the superconducting transmission line tube 5 for sealing.
