DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example: Figure 1-5As shown, the utility model provides a turbine controller for a steam turbine, comprising an upper shell 1 and a lower shell 11, wherein support holes 111 are provided at diagonal positions at the top end of the lower shell 11, and a stabilizing rod 12 is rotatably provided inside the support hole 111, and stabilizing holes 13 are provided at diagonal positions at the top end of the upper shell 1, and a through hole 14 is provided at the top of the stabilizing rod 12, and symmetrically distributed clamping blocks 15 are movably provided inside the through hole 14, and two of the clamping blocks 15 are fixedly connected by a first spring 16, and a collar 17 is movably provided on the outer side of the stabilizing rod 12, and a groove 18 is provided at the top of the support hole 111, and the collar 17 and the groove 18 are used in combination, and symmetrically distributed fixing holes 19 are provided on both sides of the upper shell 1 close to the stabilizing hole 13.

[0019] The top of the lower shell 11 is provided with symmetrically distributed card slots 2 , and the bottom of the upper shell 1 is fixedly mounted with symmetrically distributed card plates 21 , which are movably carded in the card slots 2 .

[0020] The lower shell 11 is provided with symmetrically distributed movable rods 3 on both sides close to the card slot 2, and a push plate 31 is fixedly installed on one side of the movable rod 3 close to the card slot 2. The top of the push plate 31 is in a trapezoidal state, so that when the card plate 21 and the push plate 31 are in contact, the push plate 31 is better pushed to move in the direction away from the card slot 2; the push plate 31 is located inside the card slot 2, and a fixing ring 32 is fixedly sleeved on the outer side of the movable rod 3, and a second spring 33 is fixedly installed on the side of the fixing ring 32 away from the push plate 31. The lower shell 11 is fixedly provided with symmetrically distributed connection frames on both sides close to the movable rod 3 34, the movable rod 3 passes through the connecting frame 34, and the other side of the second spring 33 is fixedly connected to the connecting frame 34. When the card plate 21 enters the card slot 2 and descends, the card plate 21 pushes the push plate 31 to move in the direction away from the card slot 2, so that the push plate 31 drives the movable rod 3 and the fixed ring 32 to move, and at the same time the fixed ring 32 squeezes the second spring 33. When the card plate 21 is completely inserted into the card slot 2, the second spring 33 releases its elastic force, driving the push plate 31 to move in the direction of the card plate 21, so that the push plate 31 continues to squeeze the card plate 21, making it more stably stuck in the card slot 2 and reducing shaking.

[0021] Both sides of the top of the upper shell 1 are provided with evenly distributed heat dissipation grooves 4. By providing the heat dissipation grooves 4, the temperature inside the controller is reduced and the service life is increased.

[0022] Brackets 5 are fixedly installed on both sides of the upper shell 1 near the fixing hole 19, and a push rod 51 is movably penetrated in the middle of the bracket 5. By pressing the push rod 51 in the direction of the fixing hole 19, the push rod 51 can push the block 15 in the fixing hole 19 back into the through hole 14, so as to facilitate the disassembly of the upper shell 1 and the lower shell 11; the push rod 51 and the bracket 5 are fixedly connected by the third spring 6, and the third spring 6 is provided to facilitate the resetting of the push rod 51.

[0023] The top and bottom ends of the through hole 14 are both provided with limiting grooves 7, and the top and bottom ends of the two clamping blocks 15 are both fixedly installed with limiting blocks 71, and the limiting blocks 71 are movably clamped in the limiting grooves 7. By setting the limiting grooves 7 and the limiting blocks 71, the clamping blocks 15 are prevented from falling from the through hole 14.

[0024] Working principle: In actual use, the upper shell 1 is placed above the lower shell 11, so that the stabilizing rod 12 enters the stabilizing hole 13. At this time, the upper shell 1 pushes the collar 17 down until it enters the groove 18, and the block 15 is no longer limited by the collar 17, so that the compressed first spring 16 drives the two blocks 15 to move backwards until they fit the inner wall of the stabilizing hole 13, and then the block 15 is driven to rotate by rotating the stabilizing rod 12. When the block 15 rotates to a certain angle and reaches the same horizontal position as the fixing hole 19, the compressed first spring 16 drives the block 15 to enter the fixing hole 19, completing the installation of the upper shell 1 and the lower shell 11. By pressing the block 15, it re-enters the through hole 14, completing the disassembly of the upper shell 1 and the lower shell 11; by providing the card slot 2 and the card plate 21, the stability of the connection between the upper shell 1 and the lower shell 11 is improved, making it more firm and increasing its service life.

[0025] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
