Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy steering pipelines, in particular to a water conservancy steering pipeline provided with a buffer water flow impact structure. Background Technique

[0002] A water conservancy steering pipeline is a special pipeline system used to change the direction of water flow in water conservancy projects to meet the needs of irrigation, drainage, water supply or other water conservancy facilities, thereby ensuring the normal operation of water conservancy projects;

[0003] When the existing water conservancy steering pipeline is in use, since the water flow has inertia when flowing in the pipeline, when the direction of the water flow suddenly changes, due to the effect of inertia, the water flow will continue to flow along the original direction, which will generate a large impact force on the turning point. Therefore, the water conservancy steering pipeline needs to be provided with a buffer for water flow impact.

[0004] In order to overcome the above defects, the prior art (Chinese patent with application number: 201821633887.8, application date: October 9, 2018) discloses a water conveyance pipeline with a water flow buffering and diverting device. By opening the eighth butterfly valve, the third flow regulating and pressure regulating valve, and the fifth butterfly valve and closing the seventh butterfly valve and the sixth butterfly valve, the first main pipe passes through the outlet pipe of the regulating pool to play a buffering and regulating role, and then enters the second main pipe through the outlet pipe of the regulating pool. Then, according to the water demand situation, the first butterfly valve and the second butterfly valve are opened for water conveyance, improving the working efficiency of the pipeline water conveyance system.

[0005] Although the prior art can solve the buffering and regulation of the water flow in the water conveyance pipeline, it involves the opening and closing of multiple valves, increasing the complexity of operation. The frequent opening and closing of the valves will cause a certain impact on the pipeline system. In the long run, it may affect the stability of the system. Therefore, the effect of buffering the water flow impact is not good, and it does not have the functions of wear resistance and corrosion prevention for the water conveyance pipeline, reducing the overall performance and durability, and it does not have the function of fixing the water conveyance pipeline, reducing the stability of the pipeline.

[0006] Therefore, we propose a water conservancy steering pipeline provided with a buffer water flow impact structure, which can well solve the above problems. Content of the Utility Model

[0007] The purpose of the present utility model is to provide a water conservancy diversion pipeline provided with a buffer water flow impact structure, so as to solve the problems raised in the above-mentioned background technology. When a water conservancy diversion pipeline provided with a buffer water flow impact structure on the current market is in use, due to the opening and closing of multiple valves, the complexity of operation is increased. The frequent opening and closing of the valves will cause a certain impact on the pipeline system. In the long run, it may affect the stability of the system, resulting in poor buffer effect of the water flow impact, and it does not have wear resistance and corrosion prevention for the water conveyance pipeline, reducing the overall performance and durability, and it does not have fixation for the water conveyance pipeline, reducing the stability of the pipeline.

[0008] To achieve the above purpose, the present utility model provides the following technical solutions: A water conservancy diversion pipeline provided with a buffer water flow impact structure, including a diversion pipeline body and a buffer elbow.

A fixed sleeve plate is sleeved on the outer wall of the diversion pipeline body.

[0010] The diversion pipeline body includes a pressure-resistant inner pipe. A buffer layer is sleeved on the inner wall of the pressure-resistant inner pipe. A wear-resistant coating is coated on the inner wall of the buffer layer. A thickening layer is wrapped on the outer wall of the pressure-resistant inner pipe.

[0011] As a preferred technical solution of this application, an anti-slip pad is fixedly connected to the inner wall of the fixed sleeve plate. A connecting plate is fixedly installed on the top of the fixed sleeve plate. A support sleeve is fixedly connected to the front of the fixed sleeve plate. A telescopic plate penetrates through the inside of the support sleeve. A number of clamping holes are formed in the telescopic plate.

A mounting plate is fixedly installed on the front of the clamping rod. A pull rod is fixedly connected to the front of the mounting plate. Springs are fixedly installed on both sides of the pull rod.

[0013] As a preferred technical solution of the present application, the buffer elbow is detachably connected to the steering pipe body, and the steering pipe body is matched with the fixed sleeve plate. When the external water flow passes through the buffer elbow through the upper connecting pipe, vibration will be generated due to the centrifugal force, enabling the buffer elbow to absorb and disperse this vibration energy, reducing the vibration amplitude and impact of the water flow entering the steering pipe body subsequently.

[0014] As a preferred technical solution of the present application, the buffer layer is closely attached to the compression inner pipe. The buffer layer is made of foam aluminum, and the compression inner pipe is made of a metal pipe. A thickening layer made of a metal wire mesh is wrapped around the outer wall of the compression inner pipe to enhance the compression resistance and structural stability of the steering pipe.

[0015] As a preferred technical solution of the present application, the compression inner pipe is fixedly connected to the thickening layer, and the thickening layer is a metal wire mesh. A thickening layer made of a metal wire mesh is wrapped around the outer wall of the compression inner pipe to enhance the compression resistance and structural stability of the steering pipe.

[0016] As a preferred technical solution of the present application, the number of the fixed sleeve plates is two, and the two fixed sleeve plates are designed to be hinged and rotatable. The connecting plate connected by the fixed sleeve plate is sleeved on the steering pipe body upward or downward, and the fastening bolts penetrate through each connecting plate to install the fixed sleeve plate on the outer wall of the steering pipe body.

[0017] As a preferred technical solution of the present application, the telescopic plate is movably connected to the support sleeve, and the support sleeve is movably connected to the clamping rod.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 - 6 , the present invention provides the following technical solutions:

[0033] Embodiment 1: To solve the problem that when a water conservancy steering pipeline with a buffer water flow impact structure on the market is in use, due to the opening and closing of multiple valves, the operation complexity is increased, and the frequent opening and closing of the valves will cause a certain impact on the pipeline system. In the long run, it may affect the stability of the system, resulting in poor buffer effect of the water flow impact. Reference can be made to Figure 1 - Figure 3 and Figure 6 , which includes a steering pipeline body 1 and a buffer elbow 2. The buffer elbow 2 includes an elbow housing 6. A upper connecting pipe 7 is fixedly connected to the right side of the elbow housing 6. A lower connecting pipe 8 is fixedly connected to the bottom of the elbow housing 6. A sealing gasket 9 is fixedly installed at the bottom of the lower connecting pipe 8. It also includes: a lower conveying pipe 4 is flange-connected to the lower part on the left side of the steering pipeline body 1. The lower connecting pipe 8 is flange-connected to the top on the right side of the steering pipeline body 1. The upper connecting pipe 7 is flange-connected to the right side of the upper conveying pipe 3. A fixed sleeve plate 5 is sleeved on the outer wall of the steering pipeline body 1. The steering pipeline body 1 includes a pressure-resistant inner pipe 12. A buffer layer 10 is sleeved on the inner wall of the pressure-resistant inner pipe 12. A wear-resistant coating 11 is coated on the inner wall of the buffer layer 10. A thickening layer 13 is wrapped on the outer wall of the pressure-resistant inner pipe 12. An anti-corrosion coating 14 is coated on the outer wall of the thickening layer 13. The buffer elbow 2 and the steering pipeline body 1 are detachably connected. The steering pipeline body 1 and the fixed sleeve plate 5 are matched with each other. The buffer layer 10 and the pressure-resistant inner pipe 12 are closely attached. The buffer layer 10 is made of foam aluminum, and the pressure-resistant inner pipe 12 is made of a metal pipe. The pressure-resistant inner pipe 12 and the thickening layer 13 are fixedly connected, and the thickening layer 13 is made of metal wire mesh.

[0034] The top of the steering pipe body 1 is flange-connected to the lower connecting pipe 8 provided on the buffer elbow 2 by the staff, so that the gasket 9 provided on the lower connecting pipe 8 is sleeved on the inner wall of the steering pipe body 1, thereby preventing liquid leakage at the connection. Then, the upper conveying pipe 3 and the lower conveying pipe 4 are respectively flange-connected to the upper connecting pipe 7 provided on the steering pipe body 1 and the buffer elbow 2, so that the buffer elbow 2 is installed between the steering pipe body 1 and the external pipe. Thus, when the external water flow passes through the upper connecting pipe 7 and through the buffer elbow 2, vibrations will be generated due to the centrifugal force, enabling the buffer elbow 2 to absorb and disperse these vibration energies, reducing the vibration amplitude and impact of the water flow entering the steering pipe body 1 subsequently. The steering pipe body 1 is composed of a buffer layer 10, a wear-resistant coating 11, a pressure-resistant inner pipe 12, a thickening layer 13, and an anti-corrosion coating 14. The buffer layer 10 is made of aluminum foam, effectively absorbing fluid impact and vibration energy. The outer wall of the buffer layer 10 is wrapped with a pressure-resistant inner pipe 12 made of a metal pipe, bearing the main pressure of the fluid. At the same time, the outer wall of the pressure-resistant inner pipe 12 is wrapped with a thickening layer 13 made of a metal wire mesh, enhancing the pressure resistance and structural stability of the steering pipe. Thus, the hydraulic steering pipe has the effect of buffering water flow impact. The wear-resistant coating 11 can enhance the wear resistance of the inner wall of the pipe, preventing the particulate matter in the fluid from wearing the pipe. The anti-corrosion coating 14 can prevent the pipe from corroding in harsh environments such as humidity, acid, and alkali, further improving the overall performance and durability of the hydraulic steering pipe.

[0035] Example 2: The hydraulic steering pipe can be fixedly installed, and reference can be made to the attached Figure 1 and the attached Figure 4 - attached Figure 5 -

[0036] According to the installation position of the hydraulic steering pipeline, the connecting plate 16 connected to the fixed sleeve plate 5 is sleeved on the steering pipeline body 1 upward or downward. With the fastening bolts passing through each connecting plate 16, the fixed sleeve plate 5 is installed on the outer wall of the steering pipeline body 1. According to the installation height, manually pull each pull rod 20 outwards, so that when the pull rod 20 drives the clamping rod 22 connected to the mounting plate 21 to move outwards, the spring 23 is stretched, thereby moving the telescopic plate 18 up or down in the support sleeve 17. After the telescopic plate 18 drives the fixed plate 24 to be adjusted to the appropriate installation position, manually release each pulled pull rod 20, so that the resilience of the spring 23 drives the clamping rod 22 to pass through the support sleeve 17 and insert into the corresponding card hole 19, thereby fixing the telescopic plate 18 in the support sleeve 17. Then manually pass each positioning bolt 25 through the fixed plate 24 and insert it into the installation position, thereby fixedly installing the hydraulic steering pipeline, preventing shaking and displacement caused by water flow impact, and increasing the stability of the hydraulic steering pipeline.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
