Description

Technical Field

[0001] This application relates to the technical field of pumping stations in water conservancy projects, and in particular to a bidirectional turning and rotating control system for a full-flow pump. Background Technology

[0002] In the application of pumping stations for flood control and drainage, it is necessary for the full-flow pump to be able to rotate and turn around to drain water in order to cope with different flood conditions. Chinese Patent No. CN104314836B discloses a high-efficiency bidirectional pump device with an overall pump reversal, as well as its construction method and application. The device includes a pump pool, a pump house, a full-flow pump, a vertical wall, a control gate, a flow channel, and a crane with a hook. The full-flow pump is installed in the pump pool. Vertical walls, control gates, and flow channels are respectively set at both ends of the pump pool. The pump house and the crane are located above the pump pool, with the crane located inside the pump house.

[0003] When using a full-flow pump for drainage operations, if the drainage direction of the full-flow pump needs to be changed, the full-flow pump needs to be lifted out of the water for adjustment and reinstallation. This also requires hoisting equipment and multiple workers to operate, which increases operating costs and is time-consuming and labor-intensive, making it difficult to be widely used in water conservancy projects. Summary of the Invention

[0004] To enable a full-flow pump to turn in water, this application provides a bidirectional turning and rotation control system for a full-flow pump.

[0005] A bidirectional turning and rotation control system for a full-flow pump includes a full-flow pump base, on which a full-flow pump is fixedly connected. One side of the full-flow pump is provided with a connecting pipe for drainage. At the end of the full-flow pump away from the full-flow pump base, a reducer is provided for driving the full-flow pump to rotate. A drive shaft connecting the full-flow pump and the reducer is provided between the two. At the end of the full-flow pump base away from the full-flow pump, a rotating mechanism is provided for assisting the rotation of the full-flow pump.

[0006] By adopting the above technical solution, a rotating mechanism is set below the axial flow pump to drive its rotation. The axial flow pump is then driven to rotate through a sliding mechanism and a reducer. When the axial flow pump needs to be turned around during drainage operations, it can be turned around directly underwater without having to lift the axial flow pump out of the water. This reduces operating costs and makes it easy to be widely used in water conservancy projects.

[0007] A further configuration of the present invention is as follows: the rotating mechanism includes a rotating frame, a rotating frame support plate is fixedly connected to the rotating frame, the rotating frame support plate is fixedly connected to the base of the full-flow pump, a pressure cap is rotatably connected to one end of the rotating frame away from the base of the full-flow pump, a support seat is fixedly connected to one end of the pressure cap away from the rotating frame, an end cap is fixedly connected to one end of the support seat away from the pressure cap, and a rotating shaft is fixedly connected inside the rotating frame, the rotating shaft being rotatably connected to the pressure cap, the support seat, and the end cap.

[0008] By adopting the above technical solution, a rotating shaft is set in the support base, pressure cover and end cover. During the process of the drive shaft driving the full-flow pump to rotate, the full-flow pump drives the rotating shaft and the rotating frame to rotate simultaneously in the support base, thereby making the rotation process of the full-flow pump smoother and more stable.

[0009] A further provision of the present invention is that: a first bolt connecting the pressure cap and the support base is provided between the two; a second bolt connecting the end cap and the support base is provided between the end cap and the support base; and a first bearing and a second bearing connecting the rotating shaft and the support base are provided between the two.

[0010] By adopting the above technical solution and connecting the end cap, support base, and gland with bolts, the connection between them can be made more secure. Installing a bearing between the rotating shaft and the support base allows for smoother rotation and connection between the two.

[0011] A further provision of the present invention is that: support plates are fixedly connected to both ends of the support base; a first support rib for reinforcement is fixedly connected to the rotating frame; and a second support rib for reinforcement is fixedly connected to the support plate of the support base.

[0012] By adopting the above technical solution, the first reinforcing bar is set to make the rotating frame connection more secure, and the second reinforcing bar is set to make the support plate of the support base more secure.

[0013] A further provision of the present invention is that a sliding mechanism for driving the full-flow pump to move is provided below the rotating mechanism. The sliding mechanism includes a slider frame fixedly connected to the support plate of the support base. A slider is fixedly connected to one end of the slider frame away from the support plate of the support base, and a slide rail is slidably connected to one end of the slider away from the slider frame.

[0014] By adopting the above technical solution, a slider frame and a slider are installed on the rotating mechanism, and a slide rail is set below the slider. The full-flow pump can be moved on the slide rail by the slider, thereby assisting the full-flow pump to turn around in the water.

[0015] A further provision of the present invention is that: the end of the slide rail away from the base of the full-flow pump is provided with a plug-in mechanism for fixing the sliding mechanism, the plug-in mechanism includes a plug-in frame, the slide rail is disposed in the plug-in frame, and a plug-in post is fixedly connected to the end of the plug-in frame away from the slide rail.

[0016] By adopting the above technical solution, a plug-in mechanism is set up at the bottom of the water where drainage operations are required. The plug-in post is inserted into the mud and sand at the bottom of the water, and the slide rail is installed on the plug-in frame. The slide rail is limited by the plug-in mechanism.

[0017] A further configuration of the present invention is as follows: the plug-in post has multiple snap-fit ​​holes, each snap-fit ​​hole has a snap-fit ​​claw, and the snap-fit ​​claw is slidably connected to the plug-in post; the plug-in post has a receiving cavity, and the receiving cavity has a plug-in rod whose end abuts against the end of the snap-fit ​​claw away from the snap-fit ​​hole; the plug-in frame has a plug-in hole at its center; the end of the plug-in rod away from the snap-fit ​​claw is located in the plug-in hole; a limit spring is fixedly connected to the end of the plug-in rod away from the plug-in frame; the end of the limit spring away from the plug-in rod is fixedly connected to the inner wall of the bottom surface of the receiving cavity; a sliding protrusion is fixedly connected to the end of the snap-fit ​​claw near the plug-in rod; a sliding groove corresponding to the sliding protrusion is formed on the inner wall of the bottom surface of the receiving cavity, and the sliding protrusion is inserted into the sliding groove; a sliding spring is provided between the sliding protrusion and the side wall of the receiving cavity to connect the two.

[0018] By adopting the above technical solution, a plug-in rod is set in the plug-in post. The end of the plug-in rod away from the limiting spring abuts against the bottom of the slide rail. When the slider presses down on the slide rail, the slide rail will press down on the plug-in rod. At this time, the limiting spring is in a compressed state. When the plug-in rod moves a certain distance, it will abut against the ends of the two locking claws that are close to each other. When the plug-in rod moves further downward, it will gradually push the two locking claws away from each other. At this time, the sliding spring is in a compressed state until the two locking claws are inserted into the mud and sand, thus making the plug-in post more firmly inserted in the mud and sand. When it is necessary to retract the plug-in mechanism, the slide rail is disengaged from the plug-in frame. The plug-in rod and locking claws will return to their original positions under the action of the limiting spring and the sliding spring, respectively. At this time, the plug-in post is pulled out of the mud and sand, thus retrieving the plug-in mechanism.

[0019] A further feature of the present invention is that a fixing mechanism for fixing the two is provided between the full-flow pump and the connecting pipe. The fixing mechanism includes a flow-limiting baffle. The flow-limiting baffle is fixedly connected to both pump ports of the full-flow pump, and the flow-limiting baffle is curved. A fixing groove is provided at one end of the flow-limiting baffle near the connecting pipe. A top plate is slidably connected in the fixing groove. A plurality of fixing springs are provided between the top plate and the flow-limiting baffle to connect the two. A rotating groove is provided at one end of the connecting pipe near the full-flow pump. A plurality of fixing rods are rotatably connected to the bottom of the rotating groove. A snap-fit ​​groove is provided on the flow-limiting baffle for the fixing rods to snap into. When the fixing rods are snapped into the snap-fit ​​grooves, the top plate abuts against the end of the fixing rods away from the snap-fit ​​grooves.

[0020] By adopting the above technical solution, when the axial flow pump is used for drainage, the pump inlet of the axial flow pump is aligned with the connecting pipe. When the axial flow pump is started, the top plate will move towards the connecting pipe under the action of the water flow. When the top plate moves a certain distance, it will abut against the fixing rod. When the top plate continues to move, the fixing rod will rotate under the action of the top plate's thrust until it is locked into the fixing groove. In this way, the axial flow pump and the connecting pipe are fixed together by the fixing mechanism.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. When the axial flow pump needs to turn around, it is not necessary to bring the axial flow pump out of the water. With the assistance of the sliding mechanism and the rotating mechanism set under the axial flow pump, it can be rotated in the water. 2. When the axial flow pump is used for drainage, the connecting pipe and the axial flow pump are fixed together by a snap-fit ​​mechanism to reduce the gap between the snap-fit ​​mechanism and the connecting pipe, thereby reducing the wear and tear of the axial flow pump.

[0027] Reference Figure 2 and Figure 3 A pressure cap 44 is provided between the rotating frame 41 and the support base 43. A first bolt 441 connects the pressure cap 44 and the support base 43, fixing the pressure cap 44 to the support base 43. The end of the pressure cap 44 away from the support base 43 is rotatably connected to the rotating frame 41. A third through hole 442 is opened at the center of the pressure cap 44, directly opposite the second through hole 431.

The end of the rotating shaft 42 away from the pressure cap 44 is inserted into the rotating groove 452, and the rotating shaft 42 is rotatably connected to the end cap 45.

[0028] Reference Figure 3 and Figure 4 Below the rotating mechanism 4, a sliding mechanism 5 is provided. Two slider frames 51 are fixedly connected to the end of the support plate 432 away from the second support rib 433, and the two slider frames 51 are symmetrically distributed about the rotation axis 42. A slider 52 is slidably connected to the end of the slider frame 51 away from the support plate 432. A slide rail 53 is provided at the end of the slider 52 away from the slider frame 51. The slider 52 is inserted into the slide rail 53, and the slider 52 is slidably connected to the slide rail 53. By driving the slider 52 to slide on the slide rail 53, the full-flow pump 2 moves along the slide rail 53.

[0029] Reference Figure 4A connector 6 is provided at the end of the slide rail 53 away from the slider 52. Multiple connector brackets 61 distributed along the length of the slide rail 53 are slidably connected to the side of the slide rail 53 away from the slider 52, and the slide rail 53 is fixedly connected to the connector brackets 61 by bolts. A connector hole 611 is provided at the center of the connector bracket 61. A connector post 63 is fixedly connected to the end of the connector bracket 61 away from the slide rail 53. A receiving cavity 631 is provided in the connector post 63. A connector rod 62 passes through the connector hole 611. The end of the connector rod 62 away from the slide rail 53 is inserted into the receiving cavity 631. A limit spring 621 is fixedly connected to the end of the connector rod 62 away from the slide rail 53. The end of the limit spring 621 away from the connector rod 62 is fixedly connected to the inner wall of the bottom surface of the receiving cavity 631. The end of the connector rod 62 away from the limit spring 621 is slidably connected to the connector bracket 61. The receiving cavity 631 is provided with a pair of locking claws 64, which are symmetrically arranged about the center line of the insertion rod 62. A sliding protrusion is fixedly connected to one end of each locking claw 64 closest to the other. A sliding groove corresponding to the sliding protrusion is formed on the inner wall of the bottom surface of the receiving cavity 631, and the sliding protrusion is inserted into the sliding groove. The locking claws 64 are slidably connected to the insertion post 63. A sliding spring 641 connects the sliding protrusion and the side wall of the receiving cavity 631. Two locking holes 632, communicating with the receiving cavity 631 and corresponding to the locking claws 64, are formed on the insertion post 63, and both locking claws 64 are inserted into the locking holes 632.

[0030] When it is necessary to install the slide rail 53 underwater, the insertion mechanism 6 is set along the laying direction of the slide rail 53. The end of the insertion post 63 away from the insertion frame 61 is inserted into the mud and sand at the bottom of the water. At this time, the slide rail 53 is set on the end of the insertion frame 61 away from the insertion post 63, and the slider 52 abuts against the slide rail 53. At this time, the slide rail 53 receives pressure, thereby pressing down the insertion rod 62, and the limit spring 621 is in a compressed state. When the insertion rod 62 moves a certain distance, the insertion rod 62 will push the two locking claws 64 away from each other. The sliding spring 641 is in a compressed state, and the locking claws 64 will gradually protrude from the locking hole 632 and insert into the mud and sand, thereby making the insertion post 63 more stable. When it is necessary to recycle the plug-in mechanism 6, first remove the plug-in bracket 61 from the slide rail 53. At this time, the plug-in rod 62 will slide towards the plug-in bracket 61 under the action of the limit spring 621. When it slides a certain distance, the plug-in rod 62 will separate from the locking claw 64. At this time, the locking claw 64 will slide towards the plug-in post 63 under the action of the sliding spring 641, so that the locking claw 64 will retract into the plug-in post 63 from the mud and sand. Then, the plug-in post 63 will be pulled out from the mud and sand, thus achieving the purpose of recycling the plug-in mechanism 6 for multiple uses.

[0031] Reference Figure 2 , Figure 4 and Figure 5A fixing mechanism 7 is provided at the connection between the full-flow pump 2 and the connecting pipe 22. The fixing mechanism 7 includes a flow-limiting baffle 71 with an arc-shaped surface. Flow-limiting baffles 71 are provided at both pump inlets of the full-flow pump 2, and the flow-limiting baffles 71 are fixedly connected to the full-flow pump 2. A fixing groove 711 is provided on the inner side wall of the flow-limiting baffle 71, and a top plate 72 is provided in the fixing groove 711, and the top plate 72 is slidably connected to the flow-limiting baffle 71. Multiple evenly spaced fixing springs 73 are provided between the top plate 72 and the inner side wall of the fixing groove 711, connecting the two. The fixing springs 73 are distributed around the axis of the flow-limiting baffle 71. A rotating groove is provided at the end of the connecting pipe 22 near the full-flow pump 2, and multiple evenly spaced fixing rods 221 are provided on the connecting pipe 22, distributed around the axis of the rotating groove. The fixing rods 221 are L-shaped. The fixing rod 221 is hinged to the bottom of the rotating groove, and a torsion spring is provided at the hinge point between the fixing rod 221 and the bottom of the rotating groove. The flow limiting baffle 71 is provided with a snap-fit ​​groove 712 corresponding to the fixing rod 221.

[0032] When drainage is required, the pump inlet of the full-flow pump 2 is inserted into the connecting pipe 22, and the full-flow pump 2 is started simultaneously. Water flows from the inlet pipe into the connecting pipe 22 from the end furthest from the connecting pipe 22. At this time, the top plate 72 will move closer to the connecting pipe 22 under the action of the water flow. When the top plate 72 moves a certain distance, it will abut against the fixing rod 221, thereby pushing the fixing rod 221 and causing it to rotate around the hinge point between the fixing rod 221 and the bottom of the rotating groove. At this time, the torsion spring is in a stretched state. When the fixing rod 221 rotates a certain angle, it will enter the locking groove 712, locking the fixing rod 221 onto the flow-limiting baffle 71, thus fixing the connecting pipe 22 and the full-flow pump 2, making it difficult for them to move during drainage operations.

[0033] The implementation principle of this embodiment is as follows: A plug-in mechanism 6 is set at the bottom of the water where drainage is required, and a sliding mechanism 5 is set on the plug-in mechanism 6. The full-flow pump 2 is slidably connected to the slide rail 53 via the slider 52. By driving the slider 52, the pump port of the full-flow pump 2 is aligned with the connecting pipe 22. At this time, the control fixing mechanism 7 fixes the full-flow pump 2 and the connecting pipe 22. The full-flow pump 2 is started, and water is introduced into the connecting pipe 22 through the full-flow pump 2 to carry out drainage. When the full-flow pump 2 needs to change the drainage direction, the full-flow pump 2 is turned off first. At this time, the water flow pushing the top plate 72 disappears, and the top plate 72 will slide away from the connecting pipe 22 under the action of the fixing spring 73. At this time, the fixing rod 221 will rotate away from the flow limiting baffle 71 under the action of the torsion spring, thereby opening the fixing mechanism 7 and separating the connecting pipe 22 from the full-flow pump 2. Simultaneously, the drive reducer 3 drives the drive shaft 21 to rotate, thereby driving the full-flow pump 2 to rotate, which in turn drives the rotating shaft 42 to rotate, thereby causing the rotating frame 41 and the pressure cover 44 to rotate relative to each other until the other pump port of the full-flow pump 2 is directly facing the connecting pipe 22. At this time, the full-flow pump 2 is fixed to the connecting pipe 22 again by the fixing mechanism, and the full-flow pump 2 is started to carry out drainage operation, thereby achieving the purpose of turning in the water without having to move the full-flow pump 2 out of the water.
