Description

TECHNICAL FIELD

[0001] The present application belongs to the field of river pipeline layout, and particularly relates to a large-diameter pipeline without abutment in a river and a floating-preventing device thereof. BACKGROUND

[0002] Prior art and defects:

[0003] The purpose of tail water transfer is to collect, process and discharge the first-stage enhanced tail water of a water purification plant through a pipeline, so as to reduce the pollution to river water. Because it is a temporary project, the pipeline will be recycled after the project is completed, and therefore the pipeline cannot be provided with an abutment. According to the tail water flow of the water purification plant, the diameter of the pipeline is designed to be 1.2 meters. The tail water is intermittently discharged, and if the water quantity in the pipeline is insufficient, the pipeline will float and cause unsafe factors. The floating-preventing device is arranged to make the pipeline always stably sink in the river bottom and not float.

[0004] Difficulty and significance of solving the above technical problems:

[0005] Therefore, based on these problems, it has important practical significance to provide a large-diameter pipeline without abutment in a river and a floating-preventing device thereof, which can make the pipeline always stably sink in the river bottom. SUMMARY

[0006] The present application aims to provide a large-diameter pipeline without abutment in a river and a floating-preventing device thereof, which can make the pipeline always stably sink in the river bottom, to solve the technical problems in the prior art.

[0007] The technical scheme adopted by the present application to solve the technical problems in the prior art is:

[0008] The floating-preventing device of the large-diameter pipeline without abutment in a river comprises a water supplementing tank with an opening on one side, a water inlet grille is arranged on the top of the water supplementing tank, a water sealing floating plate is arranged below the water inlet grille, the water sealing floating plate is driven to move by a water sealing floating ball, a floating plate baffle is arranged between the water sealing floating plate and the water inlet grille to divide the water supplementing tank into two parts, a water inlet hole is arranged on the floating plate baffle, when the water sealing floating ball floats up, the upper surface edge of the water sealing floating plate is in surface contact with the lower surface edge of the floating plate baffle, the two parts are not communicated, when the water sealing floating ball sinks down, the water sealing floating plate is separated from the floating plate baffle, and the two parts are communicated through the water inlet hole.

[0009] When the water in the pipeline is sufficient, the water sealing floating plate is closed by the water supplementing tank relying on the buoyancy of the water sealing floating ball, to form a closed space and prevent the river water from entering the pipeline; when the water in the pipeline is insufficient, the water sealing floating ball falls down, the river water enters the pipeline, and until the water quantity meets the condition, the water sealing floating ball props up the water sealing floating plate to close the water sealing floating plate.

[0010] The application can also adopt the following technical solutions.

[0011] In the large-diameter pipeline anti-floating device without abutment in the river channel, further, the number of the water sealing floating balls is four, and the water sealing floating balls and the water sealing floating plates are fixed with each other.

[0012] In the large-diameter pipeline anti-floating device without abutment in the river channel, further, the water inlet grid is a grid structure.

[0013] The river water can smoothly enter the water supplement tank, and the sundries are prevented from entering the water supplement tank.

[0014] In the large-diameter pipeline anti-floating device without abutment in the river channel, further, the water sealing floating plates or the floating plate baffle edges are provided with sealing rubbers, when the upper surface edges of the water sealing floating plates and the lower surface edges of the floating plate baffles are in surface contact, the water sealing floating plates and the floating plate baffles are sealed by the sealing rubbers.

[0015] In the large-diameter pipeline anti-floating device without abutment in the river channel, further, the water sealing floating plates and the floating plate baffles are both upwardly inclined.

[0016] Since the water sealing floating plates and the floating plate baffles are both upwardly inclined, the water sealing floating plates and the floating plate baffles can be in surface contact.

[0017] A large-diameter pipeline without abutment in a river channel, the water conveying pipeline of the large-diameter pipeline without abutment in the river channel uses the large-diameter pipeline anti-floating device without abutment in the river channel.

[0018] In the large-diameter pipeline without abutment in the river channel, further, the water supplement tank is fixed at the tail water outlet, and the water conveying pipeline cuts a rectangular hole with a length of 1.5 m and a height of 0.75 m, and is welded and sealed with the opening of the water supplement tank.

[0019] After the tail water is input into the pipeline, under the condition that the water quantity is satisfied, the pipeline is sunk in the river bottom, at this time, the buoyancy of the water sealing floating ball lifts up the water sealing floating plate, and the river water cannot enter the pipeline.

[0020] Since the input tail water into the pipeline is intermittent, when the tail water is insufficient, the water sealing floating ball falls along with the water surface in the pipeline, the river water enters the pipeline, until the water quantity is satisfied, the water sealing floating ball supports the water sealing floating plate to close the water sealing floating plate.

[0021] In summary, the application has the following advantages and positive effects:

[0022] 1. The application has simple structure, convenient use and reliable performance, is the anti-floating device for the requirement that the pipeline without abutment in the river channel is sunk in the river bottom, and adopts the new type anti-floating device to achieve the effect that the pipeline is always stably sunk in the river bottom.

[0029] The following is combined Figs. 1 to 3 The present invention will be described in detail.

[0030] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0031] Example 1:

[0032] A device for preventing large-diameter pipelines from floating in a river channel without anchorage piers, comprising two water supply boxes with an opening on one side, a water inlet grid 5 provided on the top of the water supply box, a water sealing float 3 provided below the water inlet grid, the water sealing float being driven to move by a water sealing float 6, a float baffle 4 separating the water supply box into two parts provided between the water sealing float and the water inlet grid, a water inlet hole provided on the float baffle, when the water sealing float floats up, the upper surface edge of the water sealing float contacts the lower surface edge of the float baffle, and the two parts are blocked, and when the water sealing float sinks, the water sealing float separates from the float baffle, and the two parts are connected through the water inlet hole.

[0033] When there is sufficient water in the pipeline, the water supply tank relies on the buoyancy of the water-sealing float to close the water-sealing float plate, forming a closed space to prevent river water from entering the pipeline; when there is insufficient water in the pipeline, the water-sealing float falls and river water enters the pipeline until the water volume meets the conditions, and the water-sealing float supports the water-sealing float plate to close it.

[0034] Further, the number of the water sealing floating balls can be four, and the water sealing floating balls are fixed with the water sealing floating plate.

[0035] It should be noted that the water inlet grille is a grid structure.

[0036] The river water can smoothly enter the water replenishing tank, and the sundries are prevented from entering the water replenishing tank.

[0037] It should be noted that the water sealing floating plate or the floating plate baffle edge is provided with sealing rubber, and when the upper surface edge of the water sealing floating plate is in surface contact with the lower surface edge of the floating plate baffle, the water sealing floating plate and the floating plate baffle are sealed by the sealing rubber.

[0038] It should be noted that the water sealing floating plate and the floating plate baffle are both upwardly inclined.

[0039] Since the water sealing floating plate and the floating plate baffle are both upwardly inclined, the water sealing floating plate and the floating plate baffle can be in surface contact.

[0040] Embodiment two:

[0041] A river channel non-pier large-diameter pipeline, the water pipeline of the river channel non-pier large-diameter pipeline uses the river channel non-pier large-diameter pipeline anti-floating device of any one of the above.

[0042] It should be noted that the water replenishing tank is fixed at the tail water outlet, and the water pipeline 1 cuts out a rectangular hole with a length of 1.5 meters and a height of 0.75 meters, and is welded and sealed with the opening of the water replenishing tank.

[0043] The use process of the embodiment:

[0044] After the related devices in the water replenishing tank are completed, the water replenishing tank is fixed at the tail water outlet, and the water pipeline cuts out a hole with the same size as the water replenishing tank, and is welded and sealed. After the tail water is input into the pipeline, the pipeline is sunk in the river bottom under the condition of meeting the water quantity, at this time, the buoyancy of the water sealing floating ball lifts the water sealing floating plate, and the river water cannot enter the pipeline.

[0045] Since the tail water input into the pipeline is intermittent, when the tail water is insufficient, the water sealing floating ball falls with the water surface in the pipeline, the river water enters the pipeline, and until the water quantity meets the condition, the water sealing floating ball supports the water sealing floating plate to close the water sealing floating plate.

[0046] In summary, the present application provides a river channel non-pier large-diameter pipeline and an anti-floating device thereof, which can make the pipeline always stably sunk in the river bottom.

[0047] The above embodiments have been described in detail, but the content described is only the preferred embodiments of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made in the scope of the present application should still belong to the patent coverage of the present application.
