Through the arrangement of the elastic connecting arm 45 and the collecting box 46, the collecting box 46 can take out part of the cooling liquid and sprinkle the cooling liquid into the upper space of the liquid storage shell 15 along with the clockwise rotation of the swing arm 42;
since the pressure relief pipe 18 sprays a large amount of high-temperature water vapor to the coolant in the liquid storage casing 15, a high-temperature and high-pressure environment is maintained in the upper space of the liquid storage casing 15, and the coolant splashed by the collection box 46 can be further preheated in the space;

The second embodiment:
basically the same as the first embodiment, further: the lower surface of the carrier plate 35 is fixedly connected with a collection box 46, and the bottom of the collection box 46 is fixedly connected with the upper surface of the limiting arm 30.
Referring to fig. 6, by the arrangement of the collecting box 46, the shock generated during the lifting of the carrier plate 35 can be filtered and absorbed, so that the lifting of the carrier plate 35 can be more stable, and secondly, the movement of the carrier plate 35 is guided and limited.
The working principle is as follows: when the geothermal energy recycling efficient power generation equipment is used, the semicircular bent pipe 1 is deeply buried in a geothermal soil layer, geothermal energy in soil is utilized to heat liquid water in the semicircular bent pipe 1, so that the liquid water is rapidly heated to a boiling state, and a large amount of water vapor can be generated after the liquid water is boiled;
liquid water in the semicircular bent pipe 1 is supplemented through the liquid inlet pipe 2, and vapor is led out through the exhaust pipe 3;
when a large amount of water vapor is transferred to the spherical shell 4 through the exhaust pipe 3, the turbine blades 8 and the shaft I5 in the spherical shell 4 are driven to rotate, the shaft I5 drives the output shaft on the generator 7 to rotate, and finally, the mechanical energy on the shaft I5 is converted into electric energy through the generator 7;
the utilized high-temperature steam in the spherical shell 4 is circularly transferred through the transfer pipe 9, the high-temperature steam transferred in the transfer pipe 9 is finally transferred into the liquid storage shell 15, and the high-temperature steam is liquefied under the coordination of cooling liquid in the liquid storage shell 15, so that the high-temperature steam is fully recovered; meanwhile, when high-temperature steam enters the cooling liquid in the liquid storage shell 15, heat energy can be transferred to the cooling liquid, preliminary preheating operation on the cooling liquid is achieved, and when the cooling liquid is quantitatively put into the liquid inlet pipe 2, the cooling liquid is enabled to have certain temperature and heat, and subsequent heating operation is facilitated.
The crank 14 is driven to rotate continuously through the shaft I5, the surface of the upper horizontal section of the crank 14 is driven to rotate in a fixed shaft mode through the connecting ring 13, the piston plate 11 slides in the inner wall of the piston pipe 10 in an axial limiting mode, and the crank 14 can smoothly drive the piston plate 11 to lift in the piston pipe 10 in the rotating process through the transmission of the piston rod 12, so that the air pressure in the space A in the graph 2 is obviously increased and decreased under the cooperation of the check valve I91 and the check valve II 92, when the pressure in the space A is reduced, water vapor in the spherical shell 4 can be rapidly absorbed, and the recovery operation is achieved; when the air pressure in the space A is increased, the water vapor in the space A can be finally transferred to the liquid storage shell 15 to the left through the second check valve 92;
through the arrangement of the preheating liquid supplementing device, preheating operation can be performed on the cooling liquid in the liquid storage shell 15; referring to fig. 3 and 4, in use, high-temperature water vapor is concentrated in the space B of the transfer pipe 9, and in a high-pressure environment, the piston push block 16 and the push rod 17 are pushed downward in the transfer pipe 9 against the elastic force of the compression spring 22, and once the piston push block 16 descends in the transfer pipe 9 to the lower side of the pressure relief pipe 18, the high-pressure water vapor in the transfer pipe 9 is quickly discharged and transferred through the pressure relief pipe 18;
the air pressure in the transfer tube 9 is reduced, and the push rod 17 and the piston push block 16 are quickly reset and move upwards under the action of the elastic force of the pressure spring 22.
In addition, the preheating operation of the cooling liquid in the liquid storage shell 15 is realized through high-temperature steam which is discharged out of the pressure relief pipe 18 and enters the cooling liquid in the liquid storage shell 15;
when the material taking through hole 19 on the push rod 17 descends into the cooling liquid in the liquid storage shell 15, a certain amount of cooling liquid can be collected, because the opposite surfaces of the sealing pressure column 20 and the push rod 17 are tightly attached, the cooling liquid collected in the material taking through hole 19 cannot leak in the upward moving process of the material taking through hole 19, and finally when the material taking through hole 19 is moved to the upper surface of the sealing pressure column 20, the cooling liquid collected in the material taking through hole 19 can be transferred to the liquid inlet pipe 2 along the inclined surface of the upper surface of the sealing pressure column 20, and then the cooling liquid is transferred to the semicircular elbow 1 through the liquid inlet pipe 2 to supplement the water in the semicircular elbow 1;
through the setting of auxiliary device, can further carry out preheating operation to the coolant liquid in the stock solution shell 15.

the sliding arm 29 penetrates through the horizontal section of the limiting arm 30, so that the sliding arm 29 can only perform limiting sliding on the horizontal section of the limiting arm 30, after the shaft II 27 rotates with the spiral groove II 28 on the shaft II, relative sliding is generated between the spiral groove II 28 and the sliding arm 29, and under the guide of a track on the spiral groove II 28, the sliding arm 29 performs horizontal movement leftwards or rightwards relative to the limiting arm 30, and due to the fact that the reciprocating rotation of the limiting pipe 21 and the gear I25 can be just completed by the lifting of the sliding block 24, the shaft II 27 can perform reciprocating rotation, and therefore the left-right transverse movement of the sliding arm 29 can be smoothly performed;
referring to fig. 5, the vertical rod 32 is fixedly supported by the limiting arm 30, the limiting collar 33 is supported by the vertical rod 32, and the motion track of the lifting rod 34 is limited by the limiting collar 33, so that the lifting rod 34 can only slide in an up-and-down limiting manner on the limiting collar 33;
the sliding arm 29 moves left and right to drive the rotating plate 31 to move left and right synchronously, and meanwhile, under the rotating fit of the rotating plate 31, the lifting rod 34 can smoothly slide up and down on the limiting lantern ring 33, and in the rotating process of the rotating plate 31, the air outlet at the bottom of the pressure release pipe 18 can be adjusted in a rotating mode, so that high-temperature steam sprayed out by the pressure release pipe 18 can be sprayed into cooling liquid in the liquid storage shell 15 at multiple angles, and the cooling liquid can be preheated more uniformly.
Referring to fig. 6, the carrier plate 35 is synchronously lifted and lowered by the lifting and lowering of the lifting and lowering rod 34, when the carrier plate 35 moves upwards, the lifting and lowering frame 36 on the carrier plate 35, the sliding rod 38, the lifting and lowering block 39, the return spring 40 and the limit push rod 41 on the lifting and lowering frame 36 all move upwards, in the process of moving upwards, the locking block 44 on the lifting and lowering block 39 is locked by the inclined plane pressing block two 43 on the inclined plane pressing block 42 and cannot move upwards smoothly, after the lifting and lowering block 39 is locked and cannot move upwards smoothly, the return spring 40 is compressed and deformed by the continuous upward movement of the lifting and lowering frame 36, in the process, the return spring 40 is continuously compressed and deformed, and finally, when the inclined plane pressing block one 37 on the lifting and lowering frame 36 moves upwards to contact with the bottom of the swing arm 42, under the cooperation of the inclined planes of the inclined plane pressing block one 37 and the swing arm 42, the pressing block one 37 smoothly contacts with the bottom of the inclined plane pressing block two 43 and supports the swing arm 42, the swing arm 42 rotates clockwise in fig. 6 with the top thereof as a rotation center, so that the swing arm 42 is far away from the lifting block 39, and further the locking of the two inclined pressing blocks 43 on the locking block 44 and the lifting block 39 is released, the lifting block 39 can move upwards in the lifting frame 36 to eject under the action of the elastic force on the return spring 40, in the process, one end of the locking block 44 far away from the lifting block 39 can be matched with the inclined surface on the two inclined pressing blocks 43, so that the swing arm 42 can rotate clockwise continuously, and finally the swing arm 42 can be stirred in the cooling liquid in the liquid storage shell 15, and the uniform mixing operation of the cooling liquid in each part of the liquid storage shell 15 is accelerated.
After the limiting push rod 41 penetrates through the lifting frame 36, the motion track of the lifting block 39 can be further limited, so that the motion of the lifting block is more stable; refer to fig. 6 and 7. Through the arrangement of the elastic connecting arm 45 and the collecting box 46, the collecting box 46 can take out part of the cooling liquid and sprinkle the cooling liquid into the upper space of the liquid storage shell 15 along with the clockwise rotation of the swing arm 42;
since the pressure relief pipe 18 sprays a large amount of high-temperature water vapor to the coolant in the liquid storage shell 15, a high-temperature and high-pressure environment can be maintained in the upper space of the liquid storage shell 15, and the coolant splashed by the collection box 46 can be further preheated in the space;
meanwhile, along with the upward movement of the limit push rod 41 in the above description, the clockwise rotating collection box 46 can be restricted from rotating, so that the problem that the collection box 46 is difficult to smoothly reset and rotate due to excessive rotation is avoided, and the collection box 46 is not easy to break off when colliding with the limit push rod 41 because the elastic connecting arm 45 is made of an elastic material.
