Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a water supply and drainage pipeline protection mechanism for high-rise building engineering. Background Art

[0002] As is known to all, the water used in high-rise buildings belongs to secondary water supply, which needs to be pressurized before it can be delivered to the upper floors. This means that the transportation pipeline needs to withstand greater pressure. When the staff of high-rise buildings close the valve, a water hammer effect will occur inside the pipeline (the water hammer effect refers to the inside of the water pipe, the inner wall of the pipe is smooth, and the water flows freely. When the open valve is suddenly closed, the water flow will exert a pressure on the valve and the pipe wall, mainly the valve. Due to the smooth pipe wall, the subsequent water flow quickly reaches its maximum under the action of inertia and produces a destructive effect), which can easily cause damage to the pipeline.

[0003] For example, the Chinese patent document with authorization announcement number CN216280049U, announcement date 2022-04-12, and titled "Water Hammer Elimination Device Suitable for Fluid Pipelines" includes a cylinder connected to an opening in the pipeline wall and connected to the inner cavity of the pipeline, a cylinder cover detachably sealed to the end of the cylinder away from the pipeline, a baffle located in the cylinder and movable back and forth along the axis of the cylinder, and a spring with one end abutting the baffle and the other end abutting the cylinder cover; the high-pressure fluid in the fluid pipeline flows out from the opening in the pipeline wall to impact the baffle and compress the spring. The water hammer elimination device of the utility model provides a buffer pressure area for the high-pressure fluid through the deformation of the spring and the S-shaped grid plate flow channel to reduce the water flow pressure in turn, eliminates water hammers of different sizes by using different structures to cooperate with each other in batches, and finally collects the fluid after the pressure is eliminated through a branch pipe and a one-way valve, while realizing the recycling of water resources, thereby protecting the pipeline and saving resources.

[0004] The shortcomings of the above-mentioned existing technologies are that the baffle is floatingly arranged inside the cylinder. When the valve is opened to achieve normal water flow, the water flow will squeeze the baffle inside the cylinder, so that the baffle will buffer part of the water pressure, thereby reducing the pressure of the water flow, which may easily cause insufficient water pressure in the high-rise water supply.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1-5 The embodiment of the utility model provides a water supply and drainage pipe protection mechanism for high-rise building projects, including a delivery pipe 1 and a branch pipe 2 arranged on the delivery pipe 1, a valve 3 is provided on the delivery pipe 1, a floating plate 4 is provided for the internal sliding seal of the branch pipe 2, a locking rod 5 is provided for the sliding seal on the branch pipe 2, and a locking groove 6 adapted to the locking rod 5 is provided on the floating plate 4.

[0029] Specifically, during the water flow transportation process, the valve 3 needs to be opened and closed frequently. At the moment when the valve 3 is closed, a water hammer effect will occur, which can easily cause damage to the delivery pipe 1. When eliminating the water hammer, a branch pipe 2 is usually provided on the delivery pipe 1. The branch pipe 2 is provided on the outer peripheral surface of the delivery pipe 1. The branch pipe 2 is connected to the delivery pipe 1, and the end of the branch pipe 2 away from the delivery pipe 1 is a sealing structure. A floating plate 4 is provided for sliding sealing inside the branch pipe 2. When the valve 3 is closed, the water flow will push the floating plate 4 to slide and squeeze the air inside the branch pipe 2 to achieve the effect of buffering and pressure relief, so that the water hammer effect can be eliminated as much as possible. This is prior art and will not be described in detail (see the patent document with authorization announcement number CN216280049U for details). One of the core innovations of the embodiment of the utility model is that a locking rod 5 is provided on the branch pipe 2 for sliding sealing, and a locking groove 6 adapted to the locking rod 5 is provided on the floating plate 4. When the valve 3 is in the open state, the locking rod 5 is plugged into the locking groove 6 to fix the position of the floating plate 4 to avoid the situation where the water flow is depressurized due to the movement of the floating plate 4. When the valve 3 is closed, the locking rod 5 is separated from the locking groove 6, and the floating plate 4 can slide freely to eliminate the water hammer effect.

[0030] Preferably, the radial dimension of the opening position of the branch pipe 2 is smaller than the radial dimension of the floating plate 4 , so that the floating plate 4 will not slide from the opening position of the branch pipe 2 into the interior of the conveying pipeline 1 .

[0031] Preferably, the locking groove 6 is provided with an opening, and the radial dimensions of the opening and the opening position of the locking groove 6 are larger than the radial dimensions inside the locking groove 6 , so as to facilitate the insertion of the locking rod 5 into the locking groove 6 .

[0032] Furthermore, a first spring 7 is disposed between the branch pipe 2 and the floating plate 4. Specifically, one end of the first spring 7 is fixedly connected to the inner top wall of the branch pipe 2, and the other end is fixedly connected to the upper surface of the floating plate 4. This arrangement allows the floating plate 4 to move upward under the force of water pressure, thereby simultaneously squeezing the air inside the branch pipe 2 and the first spring 7, thereby accumulating force in the first spring 7 and improving the pressure relief effect of the floating plate 4. When the water pressure inside the delivery pipe 1 decreases, the elastic force of the first spring 7 is released, causing the floating plate 4 to automatically return to its original position.

[0033] Furthermore, a power assembly is included for driving the reciprocating movement of the locking rod 5. The power assembly can be an existing reciprocating drive assembly such as a cylinder. When the valve 3 is in the open state, the output end of the cylinder extends, causing the locking rod 5 to be inserted into the locking groove 6, thereby locking the position of the floating plate 4. At this time, the floating plate 4 cannot move axially along the branch pipe 2. When the valve 3 is closed, the output end of the control cylinder contracts, thereby withdrawing the locking rod 5 from the locking groove 6. At this time, the floating plate 4 can move axially within the branch pipe 2, thereby achieving locking and unlocking of the floating plate 4.

[0034] As an alternative to the above-mentioned cylinder driving the locking rod 5 to move back and forth, the power assembly includes a first abutment rod 8 fixed to the valve 3, and a first abutment portion 9 is provided on the locking rod 5, and the first abutment portion 9 is located on the movement stroke of the first abutment rod 8; a connecting portion 10 is provided on the locking rod 5, and a movable groove is provided on the branch pipe 2, and a second spring 11 is provided between the connecting portion 10 and the movable groove. Specifically, the first abutment 9 is provided at the left end of the locking rod 5, and is preferably an arcuate surface. The first abutment rod 8 is fixedly connected to the outer peripheral surface of the valve stem, and its end is also preferably an arcuate surface. The first abutment 9 is located on the movement stroke of the arcuate end of the first abutment rod 8. The connecting portion 10 is a protruding structure on the locking rod 5, which is slidably connected to the movable groove. One end of the second spring 11 is fixed to the connecting portion 10, and the other end is fixed to the side wall of the movable groove. The effect of such a setting is that when the valve 3 is in the open state, the arcuate end of the first abutment rod 8 abuts against the first abutment 9. At this time, the locking rod 5 is inserted into the locking groove 6, and the second spring 11 is in a stressed state. When the valve 3 is switched from the open state to the closed state, , which will cause the valve stem to rotate, thereby driving the first abutting rod 8 to move away from the first abutting portion 9. At this time, the elastic force of the second spring 11 is released, thereby driving the locking rod 5 to move in the direction away from the locking groove 6. When the locking rod 5 disengages from the locking groove 6, the floating plate 4 is unlocked. When the valve 3 switches from the closed state to the open state, it will drive the valve stem to rotate in the opposite direction, thereby driving the first abutting rod 8 to rotate in the direction of the first abutting portion 9. When the first abutting rod 8 abuts against the first abutting portion 9, it will drive the locking rod 5 to move in the direction of the locking groove 6 and accumulate force on the second spring 11. After the locking rod 5 is inserted into the locking groove 6, the floating plate 4 can be locked again, thereby realizing passive locking and unlocking of the floating plate 4.

[0035] As another embodiment of the present invention, the power assembly includes a second abutting rod 12 fixedly connected to the valve 3, and a stroke amplification assembly is provided between the locking rod 5 and the second abutting rod 12. The stroke amplification assembly includes a bracket 16 slidably provided on the delivery pipe 1, a gear 13 rotatably provided on the bracket 16, a first gear plate 14 provided on the locking rod 5, and a second gear plate 15 provided on the delivery pipe 1, both of which are engaged with the gear 13, and a second abutting portion 17 provided on the bracket 16, which is located along the movement stroke of the second abutting rod 12. Specifically, the second abutment rod 12 is fixed to the outer circumferential surface of the valve stem, the bracket 16 is L-shaped, and a sliding groove is provided on the outer circumferential surface of the delivery pipe 1. One end of the bracket 16 is slidably connected to the sliding groove, and the gear 13 is rotatably arranged on its other end. In this embodiment, the locking rod 5 is not provided with a connecting portion 10, and the second spring 11 is arranged between the bracket 16 and the sliding groove. The first gear plate 14 is fixed to the right end of the locking rod 5 and is located above the gear 13. The second gear 13 is arranged on the outer circumference of the delivery pipe 1 and is located below the gear 13. The second abutment portion 17 is an arcuate surface on the bracket 16, and the end of the second abutment rod 12 close to the bracket 16 is also provided with an arcuate surface. The effect of such a setting is that when the valve 3 is in the open state, the second spring 11 is in a compressed state. When the valve 3 is switched from the open state to the closed state, the second abutment rod 12 is driven to move away from the second abutment portion 17, so that the elastic force of the second spring 11 is When the valve 3 is released, the bracket 16 will slide to the right and drive the gear 13 to move synchronously. Since the gear 13 is engaged with the first gear plate 14 and the second gear plate 15 at the same time, and since the second gear plate 15 is fixed to the conveying pipe 1, the gear 13 will rotate and move horizontally, so that the distance moved by the first gear plate 14 and the locking rod 5 is twice the moving distance of the bracket 16. In this way, during the process of the second abutting rod 12 and the second abutting portion 17 moving away from each other, the locking rod 5 can be quickly withdrawn from the locking groove 6 to achieve rapid unlocking of the floating plate 4. Conversely, when the valve 3 is switched from the closed state to the open state, the rotation of the valve stem will drive the second abutting rod 12 to rotate synchronously. During the rotation of the second abutting rod 12, the second abutting rod 12 will abut against the second abutting portion 17, thereby driving the bracket 16 to move horizontally to the left, which will also cause the locking rod 5 to be quickly inserted into the locking groove 6 to achieve rapid locking of the floating plate 4.

[0036] As another embodiment of the present invention, a wedge-shaped surface is provided on the locking rod 5, and the locking rod 5 is an elastic telescopic rod. Specifically, the wedge-shaped surface is located at one end of the locking rod 5 near the locking groove 6 and near the upper surface of the locking rod 5, and the elastic force of the first spring 7 is greater than the elastic force required for the locking rod 5 to extend and retract. The effect of this arrangement is that when the wedge-shaped end of the locking rod 5 is inserted into the locking groove 6, the lower surface of the floating plate 4 is limited by the opening position of the branch pipe 2, so that the floating plate 4 does not move downward. Under the limiting action of the lower surface of the locking rod 5 and the bottom wall of the locking groove 6, the floating plate 4 cannot move upward, thereby locking the floating plate 4. When the valve 3 is opened immediately after closing, the floating plate 4 may not have returned to its original position, and the locking rod 5 is inserted into the branch pipe 2. At this time, the elastic force of the first spring 7 is released, driving the floating plate 4 to move downward, causing the edge of the floating plate 4 to abut against the wedge-shaped surface of the locking rod 5, causing the locking rod 5 to shorten and avoid. When the locking rod 5 coincides with the locking groove 6, the elastic force of the locking rod 5 itself is released, so that the end of the locking rod 5 is inserted into the locking groove 6, thereby achieving stable locking of the floating plate 4.

[0037] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
