Description

Technical Field

[0001] The utility model belongs to the field of power generation device installation, and specifically relates to an organic working medium centripetal turbine power generation device. Background Art

[0002] The centrifugal turbine has the characteristics of large single-stage enthalpy drop, high expansion ratio, simple and compact structure. It can achieve higher efficiency at a lower flow rate. The centrifugal turbine is used as an expander in the organic Rankine cycle system, and has outstanding advantages in medium and low temperature thermal power generation. For example, the utility model patent with the authorization announcement number CN104481620B proposes an organic working fluid centrifugal turbine power generation device, including a centrifugal turbine, a reduction device and a generator. The output shaft of the centrifugal turbine and the high-speed end shaft of the reduction device are set to the same shaft, one end of the shaft is fixedly connected to the centrifugal turbine impeller, and the other end of the shaft is connected to the high-speed end gear of the reduction device; the low-speed end shaft of the reduction device is connected to the generator through a coupling.

[0003] In the existing organic working fluid centrifugal turbine power generation device, a coupling needs to be installed between the reducer and the generator. Since the installation positions of the two are relatively fixed, the coupling is prone to certain installation errors, which affects the use. Therefore, it is necessary to improve it. Summary of the invention

[0004] The purpose of the utility model is to provide an organic working fluid centripetal turbine power generation device, which solves the problem that a coupling needs to be installed between the reducer and the generator in the existing organic working fluid centripetal turbine power generation device. Since the installation positions of the two are relatively fixed, the coupling is prone to certain installation errors, which affects the use.

[0005] In order to achieve the above-mentioned purpose, the utility model provides an organic working fluid centripetal turbine power generation device, including a mounting seat, a reducer is fixedly mounted on the upper end of the mounting seat, a centripetal turbine is fixedly mounted on the left side of the reducer, a generator is slidably connected to the upper end of the mounting seat and located on the right side of the reducer, the generator and the reducer are connected by a coupling, a moving block is fixedly connected to the bottom of the generator, and the moving block is slidably connected to the inside of the mounting seat, a screw rod is installed inside the mounting seat through a bearing, the screw rod penetrates the moving block and is connected to the moving block by a thread, and a turntable is fixedly connected to the end of the screw rod away from the mounting seat.

[0006] The principle of the utility model is that when in use, after the reducer is normally installed on the mounting seat, the connecting disk is pulled by the pull button, and the connecting disk drives the limit pin to move. The limit pin moves horizontally on the turntable and disengages from the mounting seat, thereby releasing the restriction on the turntable. The turntable is then rotated by the rotating rod, and the turntable drives the lead screw to rotate, so that the moving block moves axially along the lead screw, further making the generator approach the direction of the reducer, and then the coupling is installed on the output shafts of the two. As the generator gradually approaches the reducer, the installation error of the coupling gradually decreases. Finally, the pull button is released, and under the elastic force of the spring, the limit pin is inserted into the corresponding hole groove of the mounting seat, so that the turntable and the lead screw can be locked and fixed, thereby preventing the moving block and the lead screw from loosening, and further ensuring the stability of the generator and the reducer during installation.

[0007] The beneficial effect of the utility model is that a screw rod is installed in a mounting seat with a bearing, and then a moving block is arranged at the top and bottom of the generator, the moving block is connected to the screw rod by a threaded connection, and then a turntable with a rotating rod is arranged at the end of the screw rod, so that the screw rod can be rotated more conveniently through the rotating rod and the turntable, so that the moving block can be laterally moved, and then the distance between the reducer and the generator can be adjusted, thereby facilitating the installation of the coupling between the two and reducing installation errors.

[0008] By arranging a limit pin elastically supported by a spring inside the turntable, the limit pin is inserted into the mounting seat under the elastic force of the spring, so that the turntable and the screw rod can be locked and fixed, thereby preventing loosening between the moving block and the screw rod, and further ensuring the stability of the generator and the reducer during installation.

[0009] Furthermore, a rotating rod is fixedly connected to the surface of the rotating disk, and the rotating rod is made of stainless steel. The arrangement of the rotating rod facilitates the rotation of the screw rod.

[0010] Furthermore, a ball bearing is arranged at the bottom of the moving block, and the ball bearing is slidably connected to the mounting seat. By arranging the ball bearing, the relative friction between the moving block and the mounting seat can be reduced.

[0011] Furthermore, a limit pin is slidably connected to the interior of the rotating disk, one end of the limit pin is plugged into the mounting seat, the other end of the limit pin is fixedly connected to a connecting disk, one end of the connecting disk away from the limit pin is fixedly connected to a pull button, and a spring is sleeved on the outer side of the limit pin. By inserting the limit pin into the mounting seat, the rotating disk can be limited.

[0012] Furthermore, the end of the limit pin located in the mounting seat is fixedly connected with a clamping bead, and the clamping bead is clamped with the mounting seat. The setting of the clamping bead has a positioning effect on the limit pin.

[0013] Further, one end of the spring is fixedly connected to the connecting disk, and the other end of the spring is fixedly connected to the rotating disk. Through the setting of the spring, the elastic force can be applied to the limit pin through the connecting disk.

[0014] Furthermore, a protective sleeve is fixedly connected to one end of the connection disk close to the rotating disk, and the protective sleeve is fixedly connected to the rotating disk. The setting of the protective sleeve has a protective effect on the spring. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1 , Figure 2 As shown, this embodiment provides an organic working fluid centrifugal turbine power generation device, including a mounting seat 1, a reducer 2 is fixedly mounted on the upper end of the mounting seat 1, a centrifugal turbine 3 is fixedly mounted on the left side of the reducer 2, a generator 4 is slidably connected to the upper end of the mounting seat 1 and located on the right side of the reducer 2, the generator 4 is connected to the reducer 2 through a coupling, a moving block 5 is fixedly connected to the bottom of the generator 4, and the moving block 5 is slidably connected to the inside of the mounting seat 1, a ball 7 is arranged at the bottom of the moving block 5, and the ball 7 is slidably connected to the mounting seat 1. By setting the ball 7, the relative friction between the moving block 5 and the mounting seat 1 can be reduced, a screw rod 6 is installed inside the mounting seat 1 through a bearing, the screw rod 6 passes through the moving block 5 and is connected to the moving block 5 through a thread, and a turntable 8 is fixedly connected to the end of the screw rod 6 away from the mounting seat 1. A rotating rod 9 is fixedly connected to the surface of the turntable 8, and the rotating rod 9 is made of stainless steel. By setting the rotating rod 9, it is convenient to rotate the screw rod 6.

[0021] like Figure 3As shown, the inner part of the turntable 8 is slidably connected with a limit pin 10, one end of the limit pin 10 is plugged with the mounting seat 1, and the other end of the limit pin 10 is fixedly connected with a connecting disk 12, and the end of the connecting disk 12 away from the limit pin 10 is fixedly connected with a pull button 13, and the outer side of the limit pin 10 is sleeved with a spring 14. By inserting the limit pin 10 into the mounting seat 1, the turntable 8 can be limited. The end of the limit pin 10 located in the mounting seat 1 is fixedly connected with a card bead 11, and the card bead 11 is clamped with the mounting seat 1. The setting of the card bead 11 has a positioning effect on the limit pin 10. One end of the spring 14 is fixedly connected with the connecting disk 12, and the other end of the spring 14 is fixedly connected with the turntable 8.

The provision of the protective sleeve 15 provides protection for the spring 14 .

[0022] The specific implementation process of the utility model is as follows: when in use, after the reducer 2 is normally installed on the mounting seat 1, the connecting disk 12 is pulled by the pull button 13, and the connecting disk 12 drives the limit pin 10 to move. The limit pin 10 moves horizontally on the turntable 8 and disengages from the mounting seat 1, thereby releasing the restriction on the turntable 8, and then the turntable 8 is rotated by the rotating rod 9, and the turntable 8 drives the screw rod 6 to rotate, so that the moving block 5 moves axially along the screw rod 6, further making the generator 4 approach the direction of the reducer 2, and then the coupling is installed on the output shafts of the two.

Finally, the pull button 13 is released, and under the elastic force of the spring 14, the limit pin 10 is inserted into the corresponding hole groove of the mounting seat 1, which can lock and fix the turntable 8 and the screw rod 6, thereby preventing the loosening between the moving block 5 and the screw rod 6, and further ensuring the stability of the generator 4 and the reducer 2 during installation.

[0024] By arranging a limit pin 10 elastically supported by a spring 14 inside the turntable 8, the limit pin 10 is inserted into the mounting seat 1 under the elastic force of the spring 14, so that the turntable 8 and the screw rod 6 can be locked and fixed, thereby preventing the loosening between the moving block 5 and the screw rod 6, and further ensuring the stability of the generator 4 and the reducer 2 during installation.
