Description

Technical Field

[0001] This invention relates to the field of water conservancy and hydropower engineering technology, specifically to a pipeline support device for water conservancy and hydropower engineering. Background Technology

[0002] In water conservancy and hydropower projects, pipelines typically need to transport large volumes of water at high pressures. Pipeline support devices can provide stable support for the pipelines, preventing them from deforming, bending, or even breaking due to their own weight, internal water pressure, and external environmental factors such as wind and earthquakes, thus ensuring the safe and stable operation of the project.

[0003] For example, a pipeline support device for water conservancy and hydropower engineering, as disclosed in announcement number CN220286631U, includes an upper support ring, a lower support ring, and an adjusting box. The adjusting box has a movable groove inside, and an adjusting structure is installed inside the movable groove. Support legs are installed around the bottom of the adjusting box, and a first slot is opened at the top of each support leg. A lifting structure is installed inside the first slot, and the lifting structure includes a lifting rod, an adjuster, and rollers. The lifting rod is slidably connected to the inner wall of the first slot, and multiple sets of slots are opened on one side of the lifting rod. The adjuster is installed on the outside of the support leg, with one end passing through the support leg and rotatably connected inside the slot. The rollers are located at the bottom of the lifting rod and rotatably connected to the inner wall of the first slot. Through the design of the adjusting and buffering structures, the position of the fixed pipe sleeve can be easily adjusted, reducing vibrations caused by water impact within the pipeline, thereby reducing damage to the device and increasing its service life and practicality.

[0004] However, when a valve is suddenly closed or opened, the water flow will generate huge pressure fluctuations due to inertia (reaching tens to hundreds of times the normal pressure). This pressure change not only causes physical vibration of the pipeline, but also longitudinal free vibration when the natural frequency of the pipeline matches the frequency of the medium carried by the fluid or other external factors. This can easily damage pipeline connections, supports, and other parts, and may lead to pipeline instability. Existing solutions typically use the elasticity of springs for support and fixation. However, spring supports require precise adjustment of the preload, and the screw length and spring compression must be repeatedly calibrated during installation. This operation is time-consuming and prone to deviation. If the installation position is skewed or the horizontal surface is uneven, the spring may be unevenly stressed, making the pipeline unstable and accelerating the wear of interface components, which has certain defects.

[0005] Therefore, a pipeline support device for water conservancy and hydropower projects is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a pipe support device for water conservancy and hydropower projects, so as to solve the problem that longitudinal free vibration can easily damage the pipe connection and may lead to pipe instability. The existing method of directly fixing the pipe with springs has the problem of unstable fixation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a pipe support device for water conservancy and hydropower projects, comprising a base plate and a pipe body, wherein supports are symmetrically fixedly connected to the top periphery of the base plate, and a lower ring body is fixedly connected to the top of two adjacent supports; Also includes: The upper ring body is hinged to the top side of the lower ring body, a support column is fixedly connected to the top middle of the base plate, a sealing lower cover is fixedly connected to the top of the support column, a sealing upper cover is hinged to the top side of the sealing lower cover, a fixing component is provided on the inner side of the upper ring body, and a diversion component is provided on the inner side of the sealing upper cover. The fixing assembly includes side pressure plates that slide symmetrically on both sides inside the upper ring body. A movable block is slidably connected inside the side pressure plate. A push rod is fixedly connected to one side of the movable block. The push rod is slidably connected to the upper ring body. A spring is sleeved on the outside of the push rod. A collar is fixedly installed above the bottom plate. An inclined rod is slidably connected inside the collar. One end of the inclined rod is provided with an inclined surface. The push rod abuts against the inclined surface. Two movable plates are symmetrically slidably installed on the top of the base plate. A trapezoidal block is fixedly connected to one end of the diagonal rod near the movable plate. Two adjacent trapezoidal blocks abut against the same movable plate. A pressing block is fixedly connected to the upper part of the movable plate near the support column, and an arc-shaped pressure plate is symmetrically fixedly connected to the upper part of one side of the movable plate.

[0008] Preferably, the top center of the upper ring body is threaded with an upper screw, the bottom of the upper screw is rotatably connected to an upper pressure plate, a crossbar is fixedly connected to the upper part of one side of the side pressure plate, the crossbar is slidably connected to the upper ring body, a spring is sleeved on the outside of the crossbar, the two ends of the spring are fixedly connected to the outer ends of the upper ring body and the crossbar respectively, and rubber pads are symmetrically fixedly connected to the other side of the side pressure plate.

[0009] By adopting the above technical solution, when the pipeline body experiences longitudinal free vibration, the moving plate drives the clamping block and the arc-shaped pressure plate to move. The clamping block presses against the sealing lower cover, and the arc-shaped pressure plate presses against the pipeline body, thereby facilitating the sealing and limiting of the interface between the sealing lower cover and the pipeline body. This reduces the vibration of the pipeline body end and assists in sealing, while also reducing the wear of the pipeline body end and maintaining the stability of the pipeline body connection and support.

[0010] Preferably, a second spring is sleeved on the outer side of the push rod, and the two ends of the second spring are fixedly connected to the moving block and the upper ring body respectively. A lower screw is threadedly connected to the bottom middle of the lower ring body, and a lower pressure plate is rotatably connected to the top of the lower screw. A limit rod is fixedly connected to one side of the bottom of the lower pressure plate.

[0011] By adopting the above technical solution, rotating the lower screw causes the limiting rod to limit the upper screw, thereby pressing the lower pressure plate against the bottom of the pipe body.

[0012] Preferably, the limiting rod is slidably connected to the lower ring body, a vertical rod is fixedly connected between the bottom of the collar and the base plate, a spring three is sleeved on the outside of the inclined rod, and the two ends of the spring three are fixedly connected to the collar and the trapezoidal block respectively.

[0013] By adopting the above technical solution, when the pipe body experiences longitudinal free vibration, the pipe body will squeeze the moving block, causing the inclined rod to drive the trapezoidal block to move, and the trapezoidal block to stretch the spring.

[0014] Preferably, the outer sides of the support column are symmetrically fixedly connected with support rods, the movable plate is slidably connected to the support rods, and a spring four is sleeved on the outer side of the support rod. The two ends of the spring four are fixedly connected to the outer ends of the movable plate and the support rod, respectively.

[0015] By adopting the above technical solution, the trapezoidal block will also squeeze the moving plate, and the moving plate will then stretch the spring.

[0016] Preferably, a sleeve is fixedly connected to the outer side of the support column, a piston rod is fixedly connected to the side of the movable plate near the sleeve, the piston rod is slidably connected to the sleeve, and a one-way valve inlet and a one-way valve outlet are fixedly installed on the outer side of the sleeve.

[0017] By adopting the above technical solution, the moving plate will drive the piston rod to move, the piston rod will squeeze the gas inside the sleeve, and the gas will be discharged from the one-way valve outlet.

[0018] Preferably, the diversion assembly includes a screw part rotatably connected to the middle of the top of the sealing cover, a fixing block is fixedly connected to the inner top surface of the sealing cover, guide rods are symmetrically fixedly connected to the bottom of the fixing block, a lower plate is fixedly connected to the bottom of the guide rods, and the screw part is rotatably connected to the lower plate.

[0019] By adopting the above technical solution, the screw part is rotatably connected to the fixed block, and the guide rod plays a guiding and limiting role.

[0020] Preferably, a disc is threadedly connected to the outer side of the screw section, the disc is slidably connected to the guide rod, a flow divider is symmetrically rotatably connected to the outer side of the disc, a slide is rotatably connected to the bottom of the flow divider, and two lower rods are symmetrically fixedly connected to the top of the lower plate.

[0021] By adopting the above technical solution, the operator rotates the screw, the guide rod limits the disk, the rotation of the screw causes the disk to descend, and the disk causes the diverter plate to move.

[0022] Preferably, a stop block is fixedly connected to one end of the lower rod, the stop block is fixedly connected to the lower plate, the slide block is slidably connected to the lower rod, and a spring five is sleeved on the outer side of the lower rod, with the two ends of the spring five being fixedly connected to the stop block and the slide block, respectively.

[0023] By adopting the above technical solution, the diverter plate drives the slide to move. The slide moves on the outside of the lower rod and stretches the spring five, thereby unfolding the diverter plate, which facilitates the diversion of the medium inside the pipeline body and reduces the flow rate.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting a fixed component, when the pipe body experiences longitudinal free vibration, the moving plate drives the clamping block and the arc-shaped pressure plate to move. The clamping block presses against the sealing lower cover, and the arc-shaped pressure plate presses against the pipe body, thereby facilitating the sealing and limiting of the interface between the sealing lower cover and the pipe body. This reduces the vibration of the pipe body end and assists in sealing, while also reducing wear on the pipe body end and maintaining the stability of the pipe body connection and support. The specific details are as follows: By setting up a fixing assembly, the operator places the two pipe bodies into the lower rings on both sides, then closes the upper ring and fixes it to the lower ring with bolts. The ends of the pipe bodies are fixed by sealing lower and upper covers. Then, the upper screw is rotated, causing the upper pressure plate to descend. The upper pressure plate presses against the side pressure plate, which moves closer to the pipe body and moves the crossbar. The outer end of the crossbar compresses spring one, and the elastic force of spring two causes the moving block to press against the pipe body. Then, the lower screw is rotated, and the limiting rod limits the upper screw, causing the lower pressure plate to press against the bottom of the pipe body, thus achieving the positioning of the pipe body. When the pipe body subsequently experiences longitudinal free vibration, the pipe body will squeeze the moving block. The moving block compresses spring two and causes the push rod to move. The push rod squeezes the inclined surface of the inclined rod, and the inclined rod moves the trapezoidal block. The movement of the trapezoidal block stretches the third spring and squeezes the moving plate. The moving plate stretches the fourth spring and drives the piston rod to move. The piston rod squeezes the gas inside the sleeve, and the gas is discharged from the one-way valve outlet. The moving plate also drives the pressing block and the arc-shaped pressure plate to move. The pressing block presses the lower sealing cover, and the arc-shaped pressure plate presses the pipe body, thus facilitating the sealing and limiting of the interface between the lower sealing cover and the pipe body. When the moving plate resets later, the gas enters again from the one-way valve inlet, thereby slowing down the reset of the moving plate and improving the pressing effect on the lower sealing cover. This reduces the vibration of the pipe body and also re-seals the connection between the lower sealing cover and the upper sealing cover, which reduces the vibration of the pipe body end and provides auxiliary sealing. It also reduces the wear of the pipe body end and maintains the stability of the pipe body connection and support. By setting up a flow-dividing assembly, the operator fixes the lower and upper sealing covers with bolts. Both the lower and upper sealing covers have sealing rings on their inner walls to seal and fix the ends of the pipe body. By rotating the screw, the guide rod limits the disc. The rotation of the screw causes the disc to descend, which in turn moves the flow-dividing plate. The bottom ends of the two flow-dividing plates move away from each other, and the flow-dividing plate moves the slide. The slide moves outside the lower rod and stretches the spring, thus unfolding the flow-dividing plate. This facilitates the diversion of the medium inside the pipe body and slows down the flow rate, reduces flow fluctuations, and maintains a stable medium flow rate, thereby reducing the vibration of the pipe body and assisting in the stable support and fixation of the pipe body.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1 - Figure 3 The present invention provides a technical solution: a pipe support device for water conservancy and hydropower projects, including a base plate 1 and a pipe body 10. Supports 2 are symmetrically fixedly connected around the top of the base plate 1, and a lower ring body 3 is fixedly connected to the top of two adjacent supports 2.

A diagonal rod 815 is slidably connected inside the collar 814. One end of the diagonal rod 815 is provided with an inclined surface. The push rod 87 abuts against the inclined surface.

[0029] The top center of the upper ring body 4 is threaded with an upper screw 81, and the bottom of the upper screw 81 is rotatably connected to an upper pressure plate 82. A crossbar 83 is fixedly connected to the upper part of one side of the side pressure plate 84. The crossbar 83 is slidably connected to the upper ring body 4. A spring 85 is sleeved on the outside of the crossbar 83. The two ends of the spring 85 are fixedly connected to the outer ends of the upper ring body 4 and the crossbar 83, respectively. Rubber pads 86 are symmetrically fixedly connected to the other side of the side pressure plate 84.

[0030] A spring 89 is sleeved on the outside of the push rod 87. The two ends of the spring 89 are fixedly connected to the moving block 88 and the upper ring body 4, respectively. A lower screw 810 is threadedly connected to the bottom middle of the lower ring body 3. A lower pressure plate 811 is rotatably connected to the top of the lower screw 810. A limit rod 812 is fixedly connected to one side of the bottom of the lower pressure plate 811.

[0031] Two movable plates 819 are symmetrically slidably installed on the top of the base plate 1. A trapezoidal block 816 is fixedly connected to one end of the diagonal rod 815 near the movable plate 819. Two adjacent trapezoidal blocks 816 abut against the same movable plate 819. A pressing block 824 is fixedly connected to the upper part of the side of the movable plate 819 near the support column 5, and an arc-shaped pressure plate 825 is symmetrically fixedly connected to the upper part of one side of the movable plate 819.

[0032] The limiting rod 812 is slidably connected to the lower ring body 3. A vertical rod 813 is fixedly connected between the bottom of the collar 814 and the base plate 1. A spring 817 is sleeved on the outside of the inclined rod 815. The two ends of the spring 817 are fixedly connected to the collar 814 and the trapezoidal block 816 respectively.

[0033] Support rods 826 are symmetrically fixedly connected to the outer sides of the support column 5. The movable plate 819 is slidably connected to the support rods 826. A spring 818 is sleeved on the outer side of the support rod 826. The two ends of the spring 818 are fixedly connected to the outer ends of the movable plate 819 and the support rod 826, respectively.

[0034] A sleeve 820 is fixedly connected to the outside of the support column 5. A piston rod 821 is fixedly connected to the side of the movable plate 819 near the sleeve 820. The piston rod 821 is slidably connected to the sleeve 820. A one-way valve inlet 822 and a one-way valve outlet 823 are fixedly installed on the outside of the sleeve 820.

[0035] Example 1: As Figure 3 - Figure 10 As shown, the operator places the two pipe bodies 10 into the lower ring bodies 3 on both sides, then closes the upper ring body 4 and fixes the upper ring body 4 to the lower ring body 3 with bolts. The ends of the pipe bodies 10 are fixed by the sealing lower cover 6 and the sealing upper cover 7. Then, the upper screw 81 is rotated, and the upper screw 81 drives the upper pressure plate 82 to descend. The upper pressure plate 82 presses the side pressure plate 84, and the side pressure plate 84 moves closer to the pipe body 10 and drives the crossbar 83 to move. The outer end of the crossbar 83 compresses the spring 85.

[0036] The elastic force of spring 2 89 drives the moving block 88 to press the pipe body 10. Then, the lower screw 810 is rotated, and the limiting rod 812 limits the upper screw 81, so that the lower pressure plate 811 presses the bottom of the pipe body 10, thereby realizing the positioning of the pipe body 10. When the pipe body 10 subsequently experiences longitudinal free vibration, the pipe body 10 will squeeze the moving block 88. The moving block 88 compresses spring 2 89 and drives the push rod 87 to move. The push rod 87 squeezes the inclined surface of the inclined rod 815. The inclined rod 815 drives the trapezoidal block 816 to move. The trapezoidal block 816 stretches spring 3 817 and squeezes the moving plate 819. The moving plate 819 stretches spring 4 818 and drives the piston rod 821 to move.

[0037] The piston rod 821 compresses the gas inside the sleeve 820, and the gas is discharged from the one-way valve outlet 823. The moving plate 819 also drives the pressing block 824 and the arc-shaped pressure plate 825 to move. The pressing block 824 presses the sealing lower cover 6, and the arc-shaped pressure plate 825 presses the pipe body 10, thereby facilitating the sealing and limiting of the interface between the sealing lower cover 6 and the pipe body 10. When the moving plate 819 is reset later, the gas enters again from the one-way valve inlet 822, thereby slowing down the reset of the moving plate 819 and improving the pressing effect on the sealing lower cover 6. This reduces the vibration of the pipe body 10 and also re-seals the connection between the sealing lower cover 6 and the sealing upper cover 7, which reduces the vibration of the end of the pipe body 10 and provides auxiliary sealing. It also reduces the wear of the end of the pipe body 10 and maintains the stability of the pipe body 10 connection and support.

[0038] like Figure 1 and Figure 11 - Figure 14 As shown, a diversion assembly 9 is provided on the inner side of the sealing cover 7. The diversion assembly 9 includes a screw part 91 rotatably connected to the middle of the top of the sealing cover 7. A fixing block 92 is fixedly connected to the inner top surface of the sealing cover 7. A guide rod 94 is symmetrically fixedly connected to the bottom of the fixing block 92. A lower plate 93 is fixedly connected to the bottom of the guide rod 94. The screw part 91 is rotatably connected to the lower plate 93.

[0039] A disc 95 is threadedly connected to the outer side of the screw section 91. The disc 95 is slidably connected to the guide rod 94. A flow divider 96 is symmetrically rotatably connected to the outer side of the disc 95. A slide block 99 is rotatably connected to the bottom of the flow divider 96. Two lower rod bodies 98 are symmetrically fixedly connected to the top of the lower plate 93.

[0040] A stop block 97 is fixedly connected to one end of the lower rod 98. The stop block 97 is fixedly connected to the lower plate 93. The slide block 99 is slidably connected to the lower rod 98. A spring 910 is sleeved on the outside of the lower rod 98. The two ends of the spring 910 are fixedly connected to the stop block 97 and the slide block 99, respectively.

[0041] Example 2: Figure 3 and Figure 11 - Figure 14 As shown, the operator fixes the lower sealing cover 6 and the upper sealing cover 7 with bolts. The inner walls of the lower sealing cover 6 and the upper sealing cover 7 are both equipped with sealing rings to seal and fix the end of the pipe body 10. By rotating the screw part 91, the guide rod 94 limits the disk 95. The rotation of the screw part 91 drives the disk 95 to descend. The disk 95 drives the diverter plate 96 to move. The bottom ends of the two diverter plates 96 move away from each other. The diverter plate 96 drives the slide 99 to move.

[0042] The slide 99 moves outside the lower rod 98 and stretches the spring 910, thereby unfolding the diversion plate 96. This facilitates the diversion of the medium inside the pipe body 10 and slows down the flow rate, reduces flow fluctuations, and maintains a stable medium flow rate, thereby reducing the vibration of the pipe body 10 and assisting in the stable support and fixation of the pipe body 10. All components of the diversion assembly 9 are made of stainless steel to avoid corrosion by the pipe medium and extend service life.

[0043] Working principle: When using this device, firstly, as... Figure 1 - Figure 14As shown, the operator places the two pipe bodies 10 into the lower ring bodies 3 on both sides, then closes the upper ring body 4, and fixes the upper ring body 4 to the lower ring body 3 with bolts. The sealing lower cover 6 and sealing upper cover 7 are also fixed with bolts. Sealing rings are provided on the inner and outer rings of both the sealing lower cover 6 and sealing upper cover 7 to seal and fix the ends of the pipe bodies 10. By rotating the screw part 91, the guide rod 94 limits the disc 95. The screw part 91 rotates, causing the disc 95 to descend. The disc 95 drives the flow divider 96 to move, and the bottom ends of the two flow dividers 96 move away from each other. The flow dividers 96 drive the slide 99 to move. The slide 99 moves outside the lower rod body 98 and stretches the spring 910, thereby unfolding the flow dividers 96 to facilitate the diversion of the medium inside the pipe body 10 and slow down the flow rate. Then, rotating the upper screw 81 causes the side pressure plate 84 to move closer to the pipe body 10. Rotating the lower screw 810 causes the limiting rod 812 to move towards the upper... The lead screw 81 is limited, causing the lower pressure plate 811 to press against the bottom of the pipe body 10, thereby positioning the pipe body 10. When the pipe body 10 subsequently experiences longitudinal free vibration, the pipe body 10 will squeeze the moving block 88. The moving block 88 compresses the second spring 89 and drives the push rod 87 to move. The push rod 87 squeezes the inclined surface of the inclined rod 815. The inclined rod 815 drives the trapezoidal block 816 to move. The trapezoidal block 816 stretches the third spring 817 and squeezes the moving plate 819. The moving plate 819 stretches the fourth spring 818 and drives the piston rod 821 to move. The piston rod 821 squeezes the gas inside the sleeve 820. The gas is discharged from the one-way valve outlet 823. The moving plate 819 also drives the pressing block 824 and the arc-shaped pressure plate 825 to move. The pressing block 824 presses against the sealing lower cover 6, and the arc-shaped pressure plate 825 presses against the pipe body 10, thereby facilitating the sealing and limiting of the interface between the sealing lower cover 6 and the pipe body 10.
