Description

Technical Field

[0001] The present application relates to the technical field of concrete pipes, and more specifically, to a composite anti-corrosion concrete pipe. Background Art

[0002] Concrete pipes are pipes made of concrete or reinforced concrete, used to transport fluids such as water, oil, and gas. Existing pipes on the market include plain concrete pipes, ordinary reinforced concrete pipes, prestressed steel cylinder concrete pipes, and foamed concrete pipes; reinforced concrete pipes are widely used in drainage pipes such as rainwater, sewage, and water supply.

[0003] In order to improve the corrosion resistance of the pipe joints, some existing concrete pipes usually set an anti-corrosion plate at the internal connection seam to protect the internal connection gap of the pipe. After transporting some fluids for a long time, the anti-corrosion plate will be worn and the anti-corrosion effect will be reduced, so the anti-corrosion plate needs to be replaced. However, the anti-corrosion plate is mainly connected to the inner wall of the pipe by screws, which may cause damage to the inner wall of the concrete pipe during disassembly, reducing its service life.

[0004] In order to solve the above problems, the present application provides a composite anti-corrosion concrete pipe. Utility Model Content

When the moving plate loses the external force, the moving plate will be driven to move in the opposite direction under the action of the reset spring elastic force.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. Example

[0030] The present application embodiment discloses a composite anti-corrosion concrete pipe. Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a pipeline 1, the outside of the two pipelines 1 are both sleeved with auxiliary supporting mechanisms, a plurality of anti-corrosion plates 8 are evenly arranged inside the pipeline 1, two groups of fixed components are symmetrically arranged on both sides of the anti-corrosion plate 8, the two groups of fixed components include anti-corrosion plates 8, arc plates 9, movable plates 10, reset springs 12 and plug rods 11, a plug hole is opened inside the arc plate 9, the plug rod 11 is slidably inserted and connected inside the plug hole, and a cylindrical block 13 is fixedly connected to the side of the plug rod 11 away from the anti-corrosion plate 8. The anti-corrosion plate 8 is a quarter of an arc plate. When four anti-corrosion plates 8 are connected together, they can form a circle. The fixed components here are evenly distributed in a circle inside the pipeline 1.

[0031] See also Figure 3 The outer wall of the arc plate 9 is fixedly connected to the inner wall of one end of the pipe 1, and the movable plate 10 is slidably connected to the inside of the arc plate 9. The shape of the movable plate 10 is the same as that of the arc plate 9, and the arc center angle is equal. A slide groove is opened inside the arc plate 9, and the size of the slide groove is adapted to the movable plate 10, so that the movable plate 10 can move inside the arc plate 9.

[0032] See also Figure 3 A plurality of positioning holes are symmetrically provided on both sides of the anti-corrosion plate 8. One end of the insertion rod 11 close to the anti-corrosion plate 8 is slidably inserted into the interior of the positioning hole. When the insertion rod 11 is inserted into the interior of the positioning hole, the anti-corrosion plate 8 can be stably installed.

[0033] See also Figure 3 and Figure 4 A plurality of return springs 12 are symmetrically arranged on both sides of the plurality of insertion rods 11 , and one end of the return spring 12 away from the anti-corrosion plate 8 is fixedly connected to an inner wall of one side of the arc plate 9 .

[0034] When the moving plate 10 is subjected to external force and presses the return spring 12 , an elastic force will be generated under the action of its own elastic force. When the moving plate 10 loses the external force, the return spring 12 will drive the moving plate 10 to move in the opposite direction.

[0035] See also Figure 3 One end of the return spring 12 close to the anti-corrosion plate 8 is fixedly connected to the inner wall of one side of the moving plate 10 , and one end arm of the insertion rod 11 is fixedly sleeved inside the moving plate 10 .

[0036] The movable plate 10 is connected to the cylindrical block 13 via an insertion rod 11 . By pulling the cylindrical block 13 , the movable plate 10 can be driven to move synchronously via the insertion rod 11 .

[0037] See also Figure 3 A cavity is opened inside the anti-corrosion plate 8, and a first anti-corrosion layer 801 and a second anti-corrosion layer 802 are arranged inside the cavity.

[0038] Here, the first anti-corrosion layer 801 is a corundum particle layer, and the second anti-corrosion layer 802 is a tributyl phosphate plastic particle layer. By setting the first anti-corrosion layer 801 and the second anti-corrosion layer 802, the wear resistance of the overall structure can be increased while ensuring the corrosion resistance of the pipeline 1 structure.

[0039] See also Figure 1 The auxiliary support mechanism includes an upper cover plate 3, a lower cover plate 4, a fixing rod 5 and a pad 6. The upper cover plate 3 and the lower cover plate 4 are symmetrically sleeved on one end of the pipeline 1. Connection holes are opened on the front and back sides of the upper cover plate 3. Bolts 7 are slidably inserted and connected inside the connection holes. Nuts 2 are threadedly connected to the bottom of the bolts 7. Two fixing rods 5 are symmetrically arranged on both sides of the lower cover plate 4 in the same vertical plane. The end of the fixing rod 5 away from the pipeline 1 is fixedly connected to the side of the pad 6 close to the pipeline 1.

[0040] Here, the pad 6 is in a cross shape. Through the cooperation between the fixing rod 5 and the pad 6, the gripping force of the pipeline 1 on the soil can be improved, thereby facilitating the fixing of the pipeline 1.

[0041] The implementation principle of this embodiment is as follows: when disassembling, the cylindrical block 13 on one side is pulled to drive the plug rod 11 to move to the side away from the anti-corrosion plate 8, and at the same time, the movable plate 10 will be driven to squeeze the return spring 12 on one side. Under the elastic action of the return spring 12 itself, a reverse force will be generated on the movable plate 10 and the plug rod 11. Then, the reverse force at this time is smaller than the external force on the plug rod 11, and it will continue to diffuse and move outward. When the plug rod 11 is completely separated from the anti-corrosion plate 8, the remaining fixed components are operated one by one according to the above steps to achieve disassembly;

[0042] During replacement, fit the outer wall of the anti-corrosion plate 8 with the inner wall of the pipe 1, and then loosen the cylindrical block 13. At this time, the insertion rod 11 loses the external force, and only the elastic force given by the return spring 12 remains as a whole, thereby driving the insertion rod 11 to move in the opposite direction through the movable plate 10 and inserting it into the positioning hole on one side of the anti-corrosion plate 8. The remaining fixing components are operated one by one according to the above steps to achieve the installation of the anti-corrosion plate 8.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
