Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy project construction, in particular to a pipeline used in water conservancy projects. Background Art

[0002] A water conservancy project is a project built to control and allocate natural surface water and groundwater in order to achieve the purpose of eliminating harm and promoting benefits. Many accessories are required during the construction of water conservancy projects, including pipes.

[0003] The Chinese utility model patent with the authorization announcement number "CN211117970U" is specifically "a pipeline for water conservancy projects". It uses connecting springs to provide buffering support for the suspended pipeline, thereby improving the stability of the pipeline during use.

[0004] The core component used by the above-mentioned device to achieve the buffering support effect on the suspended pipe is a spring. Although the spring has a certain buffering effect, the buffering effect is very limited, and the spring is still used in water conservancy projects. Therefore, the buffering effect that can be provided to the suspended pipe is not ideal. More importantly, the buffering support of the above-mentioned device for the pipe is that the pipe is placed horizontally by default, but during the actual construction of the water conservancy project pipe, the pipe will also tilt according to the actual geographical conditions. At this time, the relevant supporting components used in the above-mentioned device cannot be tilted synchronously, resulting in a reduction in the contact area between the bottom floor mat and the construction ground, thereby reducing the support and buffering effect on the pipe. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides a pipeline for water conservancy projects, which can effectively solve the problems raised in the background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides a pipeline for water conservancy projects, comprising a water pipe and a rotating rod rotatably installed at the bottom of the water pipe, a lifting seat fixedly sleeved on the outer rod wall of the rotating rod, a threaded rod is installed in the lifting seat for lifting and sliding, a lifting plate is vertically fixedly installed at the bottom end of the threaded rod, a buffer component comprises a shaft cylinder arranged below the lifting plate, a shaft rod with a top fixedly connected to the lifting plate is elastically installed in the shaft cylinder for lifting and retracting, a plurality of buffer air holes are opened on the outer cylinder wall of the shaft cylinder through the inner cylinder cavity, and a steering support component comprises a rolling ball seat fixedly installed at the bottom of the corresponding shaft cylinder, a rolling ball is embedded in the bottom of the rolling ball seat, and a support seat is fixedly installed on the outer ball wall of the rolling ball.

[0008] Furthermore, flange mounting rings are fixedly mounted on both ends of the water pipe, and two symmetrically distributed fixing seats are also fixedly mounted on the bottom of the water pipe, and both ends of the rotating rod are rotatably mounted on the corresponding fixing seats respectively.

[0009] Furthermore, round holes are provided on both sides of the lifting seat for convenient sleeve-mounting on the outer rod wall of the rotating rod, and a worm and a worm wheel meshing with each other are rotatably installed in the lifting seat.

[0010] Furthermore, the worm wheel thread is sleeved on the outer rod wall of the threaded rod, and a through hole is provided in the bottom of the lifting seat through the inner cavity to facilitate the lifting and sliding of the threaded rod.

[0011] Furthermore, an axial cavity is provided in the shaft cylinder, and an axial hole is provided on the top of the shaft cavity through the top of the shaft cylinder to facilitate the telescopic sliding of the shaft rod.

[0012] Furthermore, a piston plate is fixedly installed at the bottom of the shaft rod and is installed in the shaft cavity in a lifting and sliding manner. The outer diameter of the piston plate is consistent with the inner diameter of the shaft cavity, and a spring is installed between the bottom of the piston plate and the bottom of the shaft cavity.

[0013] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] 1. The spring is used to absorb vibration energy and drive the piston plate to rise and fall and slide in the shaft cavity, thereby compressing the air in the shaft cavity and discharging it from the buffer air hole opened on the outer wall of the shaft cylinder. Since the air discharge speed of the buffer air hole is lower than the compression deformation speed of the spring, the overall pipeline is buffered and damped, thereby improving the stability of the pipeline during use;

[0015] 2. A lifting seat is set between the spring and the pipeline. A threaded rod that can be raised and lowered to adjust the height is set inside the lifting seat. Through the lifting and lowering adjustment of the threaded rod, the height of each support component in contact with the pipeline can be adjusted according to the actual geographical conditions, which is convenient for inclined paving of the pipeline. At the same time, the bottom of the shaft tube is connected to the support seat through a rolling ball. The support seat can automatically fit with the construction ground through the rolling of the ball, always ensuring the maximum contact area and improving the support and buffering effect on the pipeline.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0023] The utility model is further described below in conjunction with embodiments.

[0024] Example 1

[0025] Reference Figure 1-4 , which is the first embodiment of the utility model, discloses a pipeline for water conservancy projects, including a water pipe 1 and a rotating rod 13 rotatably installed at the bottom of the water pipe 1, a lifting seat 2 fixedly sleeved on the outer rod wall of the rotating rod 13, a threaded rod 24 is installed in the lifting seat 2 for lifting and sliding, and a lifting plate 25 is vertically fixedly installed at the bottom end of the threaded rod 24, and a buffer component includes a shaft cylinder 3 arranged below the lifting plate 25, and a shaft rod 32 is elastically installed in the shaft cylinder 3 for lifting and lowering, and a top thereof is fixedly connected to the lifting plate 25, and a plurality of buffer air holes 35 are opened on the outer cylinder wall of the shaft cylinder 3 through the inner cylinder cavity, and the diameter of the buffer air holes 35 is small, so that the gas discharge speed in the inner cavity of the shaft cylinder 3 is reduced, thereby realizing the buffering characteristic, and the steering support component includes a rolling ball seat 41 fixedly installed at the bottom of the corresponding shaft cylinder 3, and a rolling ball 42 is embedded in the bottom of the rolling ball seat 41, and a support seat 43 is fixedly installed on the outer ball wall of the rolling ball 42, and the rolling ball 42 can roll freely in the rolling ball seat 41, so that the support seat 43 can always fit on the tunnel ground, thereby increasing the contact area between the entire device and the ground.

[0026] Example 2

[0027] Reference Figure 1-4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: flange mounting rings 11 are fixedly mounted at both ends of the water pipe 1 to facilitate docking and assembly between the water pipes 1. Two symmetrically distributed fixing seats 12 are also fixedly mounted at the bottom of the water pipe 1. The two ends of the rotating rod 13 are rotatably mounted with the corresponding fixing seats 12 respectively. Round holes 21 that are conveniently mounted on the outer rod wall of the rotating rod 13 are opened on both sides of the lifting seat 2. The rotating rod 13 is inserted into the round hole 21 and fixedly mounted with the lifting seat 2 by welding. A worm 22 and a worm wheel 23 that mesh with each other are also rotatably mounted in the lifting seat 2. The worm wheel 23 is threadedly mounted on the outer rod wall of the threaded rod 24. A convenient threaded rod 24 is opened through the inner cavity at the bottom of the lifting seat 2 The through hole for lifting and sliding has a diameter larger than the outer diameter of the threaded rod 24, which reduces unnecessary wear of the threaded rod 24. One end of the worm 22 extends through the lifting seat 2 and is fixedly installed with a regular hexagonal rotating block 26, which is convenient for lifting and lowering the threaded rod 24 by using tools such as wrenches. An axial cavity 31 is opened in the shaft cylinder 3, and an axial hole is opened on the top of the shaft cylinder 3 to facilitate the telescopic sliding of the shaft rod 32. The diameter of the axial hole is consistent with the outer diameter of the shaft rod 32, which improves the lifting stability of the shaft rod 32. A piston plate 33 is fixedly installed at the bottom of the shaft rod 32 with a lifting and sliding installation in the shaft cavity 31. The outer diameter of the piston plate 33 is consistent with the inner diameter of the shaft cavity 31 to avoid air leakage, and a spring 34 is installed between the bottom of the piston plate 33 and the bottom of the shaft cavity 31.

[0028] The remaining structures are the same as those of Example 1.

[0029] The workflow of this utility model is as follows:

[0030] First, the water pipe 1 is laid in the tunnel. At this time, the support seat 43 automatically rotates the angle through the rolling of the ball 42 to ensure that the bottom of the support seat 43 is completely in contact with the bottom of the tunnel. Then, the hexagonal rotating block 26 is rotated by a wrench or other tool, thereby driving the worm 22 to rotate, and then driving the worm wheel 23 to mesh and rotate. Since the threaded rod 24 is threadedly installed with the worm wheel 23, the threaded rod 24 rotates synchronously due to the friction of the threaded installation. However, the bottom of the threaded rod 24 is connected to the buffer component, and the buffer component is connected to the support seat 43 at the bottom, so that the threaded rod 24 cannot rotate synchronously with the worm 22 and can only be forced to rise and fall in height, thereby driving the entire lifting seat 2 including the water pipe 1 to rise and fall, so that the water pipe 1 is laid according to the designed inclination angle;

[0031] Secondly, during the actual use of the water pipe 1, the vibration energy generated by the change in water flow will be directly transmitted to the spring 34 through the shaft rod 32. The spring 34 absorbs the vibration energy and deforms, thereby driving the piston plate 33 to descend in the shaft cavity 31, thereby discharging the air in the shaft cavity 31 below the piston plate 33 from a plurality of buffer air holes 35 opened on the outer wall of the shaft cylinder 3. However, since the air discharge speed of the buffer air holes 35 is lower than the compression deformation speed of the spring 34, the overall buffering and shock absorption of the pipeline is achieved, thereby improving the stability of the pipeline during use.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
