Description

Technical Field

[0001] The invention relates to the technical field of auxiliary equipment of a hydropower station, and more particularly to a fixed pipe with an adjustable inlet. Background Art

[0002] At present, pipelines are widely used in industrial equipment and facilities. In some specific environments, such as water collection wells and water plants, there is often a large amount of floating oil on the water surface. It is necessary to separate the floating oil on the surface from the water at the bottom layer. This type of operation requires the inlet elevation of the pipeline to change frequently with the progress of the operation under specific requirements. At present, in various work scenarios, it is achieved by opening and closing the stratified water intake valve or by using segmented telescopic pipes. The former is effective for taking the bottom water body. For taking the floating oil on the surface, it is limited by the valve elevation and cannot accurately control the taking of the upper layer. Telescopic pipes cannot be fixed well, and are prone to deformation when the pipe length is long, and are prone to jamming during the telescopic process. Summary of the invention

[0003] The purpose of the present invention is to provide a pipeline with a fixed adjustable inlet, so as to solve the technical problems in the background technology, so that the water intake elevation is controllable, the flow is stable, and the pipeline is stable.

[0006] A pipe, wherein the side wall of the pipe is provided with an opening of a preset length, and the openings of the two pipes are arranged opposite to each other; the pipes on both sides of the opening are formed by two elastic sheets;

[0007] A water inlet device is arranged between two pipes and is used to move along the opening direction of the pipes. By moving the water inlet device up and down, the water inlet on the water inlet device is controlled to be at different positions on the closed pipe to achieve stratified water intake at different altitudes. The two elastic sheets can open or close the opening under the action of the water inlet device.

[0008] In some embodiments, the pipe includes a pipe body and a tapered portion, wherein the tapered portion is composed of two elastic sheets; the open ends of the two elastic sheets are respectively sealed with the two sides of the pipe body, and the closed ends of the two elastic sheets are sealed to each other; the pipe bodies of the two pipes are fixed by connecting sheets.

[0009] In some embodiments, the water inlet device includes a water inlet device body, and installation grooves are symmetrically provided on both sides of the water inlet device body, and a seal-breaking tip is provided in the installation groove, and the seal-breaking tip is diamond-shaped, and the side walls on both sides of the installation groove are respectively inclined corresponding to the diamond-shaped side walls of the seal-breaking tip to form a re-sealing auxiliary surface; a water inlet device flow channel is provided from the side wall of the water inlet device body to the end face of the seal-breaking tip, wherein one side of the end face of the seal-breaking tip is a water inlet.

[0010] In some embodiments, the relative density of the water inlet device is between oil and water.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The structure is simple and reliable, which solves the technical problem of non-adjustable pipeline inlet.

[0013] 2. By using the clever combination of buoyancy and gravity between the float and the pipe, the pipe inlet is always controlled at about 2mm above the water surface, making the oil collection more efficient.

[0025] The following will be combined Figure 1-5 , a fixed adjustable inlet pipe involved in the embodiment of the present application is described in detail. It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation of the present application.

[0026] Embodiment 1:

[0027] like Figure 1As shown, a fixed pipe with an adjustable inlet comprises a pipe and a water inlet device, wherein the side wall of the pipe is provided with an opening of a preset length, and the openings of the two pipes are arranged opposite to each other; the pipes on both sides of the opening are composed of two elastic sheets; the water inlet device is arranged between the two pipes and is used to move along the opening direction of the pipe, and the water inlet on the water inlet device is controlled to be at different positions on the closed pipe by moving the water inlet device up and down to realize stratified water intake at different elevations; the two elastic sheets can open or close the opening under the action of the water inlet device.

[0028] The pipe 11 can balance the force of the water inlet device 21 and prevent it from getting stuck. The movement of the water inlet device 21 can be limited by a set of mounting grooves so that the water inlet device 21 can only move up and down along the inner side of the closed pipe 11.

[0029] The pipeline includes a pipeline body and a tapered portion. The pipeline body is a pipeline with a C-shaped opening in cross section. The tapered portion is composed of two elastic sheets. The open ends of the two elastic sheets are respectively sealed and connected to the two sides of the C-shaped opening of the pipeline body, and the closed ends of the two elastic sheets are sealed to each other. The pipeline bodies of the two pipelines are fixed by connecting sheets.

[0030] The relative density of the water inlet device 21 is between that of oil and water, and is 0.9×1000kg / m 3 According to the internal space, a water inlet device flow channel 22 and a water inlet 23 are arranged; and a seal breaking top 24 and a resealing auxiliary surface 25 are arranged on the outside.

[0031] like Figure 2 As shown, the water inlet device includes a water inlet device body, and mounting grooves are symmetrically arranged on both sides of the water inlet device body, and a sealing-breaking tip is arranged in the mounting groove, and the sealing-breaking tip is in a rhombus shape. The side walls on both sides of the mounting groove are respectively inclined corresponding to the rhombus side walls of the sealing-breaking tip to form a resealing auxiliary surface; a through water inlet device flow channel is arranged from the side wall of the water inlet device body to the end face of the sealing-breaking tip, wherein one side of the end face of the sealing-breaking tip is a water inlet. The water inlet device flow channel 22 and the water inlet 23 are interconnected to form an interconnected pipeline.

[0032] The seal-breaking tip 24 is helpful to separate the two tightly attached elastic sheets 13 when the water inlet device 21 moves up and down. The diamond-shaped tip is spherical in design, which can protect the elastic sheets 13.

[0033] The auxiliary sealing surface 25 assists the sealing reconstruction of the elastic sheet 13 , thereby preventing the elastic sheet 13 from wrinkling or curling, and extending the service life of the auxiliary elastic sheet 13 .

[0034] The pipe support rib 12 is arranged on the C-shaped opening side of the closed pipe 11. When the elastic sheet 13 is under the action of high water head and is subjected to a large water pressure, the pipe support rib 12 provides support for the elastic sheet 13, so that the seal of the elastic sheet 13 has a certain compressive strength, making the entire device suitable for high water head environment; the pipe support rib 12 can enhance the mechanical strength of the closed pipe 11; the pipe support rib 12 can limit the size of the C-shaped opening of the closed pipe 11 to be uniform.

[0035] The elastic sheet 13 is arranged in a herringbone shape on the C-shaped opening side of the closed pipe 11. When not subjected to external force, the elastic sheet is in a closed and sealed state. When it is stretched open by the breaking seal top 24, only the stretched part is opened, and oil and dirt flow into the pipe from then on, and the other parts remain in a closed and sealed state. When the breaking seal top 24 is removed, the elastic sheet 13 restores the closed and sealed state under the action of its own elasticity and the re-sealing auxiliary surface 25.

[0036] Combine the following Figure 3 middle Figure 3 A. Figure 3 B. Figure 4 , Figure 5 To explain:

[0037] When there is a lot of oil in the water collection well, the water inlet device 21 floats on the water surface of the water collection well due to its own buoyancy, ensuring that the water surface of the water collection well is 2 mm above the water inlet 23 of the water inlet device 21, so that the oil on the water surface of the water collection well enters the water inlet 23 of the water inlet device 21, and the water intake process is completed.

[0038] When the water level in the sump rises, the water inlet device 21 moves upward due to the buoyancy, and the breaking tip 24 at the top of the water inlet device 21 opens the elastic sheet 13 at the top of the closed pipe 11, and the re-sealing auxiliary surface 25 at the bottom of the water inlet device 21 assists in resetting the seal of the elastic sheet 13 at the bottom of the closed pipe 11. In this way, when the elevation of the water inlet device 21 changes upward, the seal at the top of the closed pipe 11 is broken and connected to the water inlet 23, and the seal at the lower part is restored.

[0039] When the water level in the sump drops, the water inlet device 21 moves downward under the action of gravity, and the breaking tip 24 at the bottom of the water inlet device 21 opens the elastic sheet 13 at the bottom of the closed pipe 11, and the upper re-sealing auxiliary surface 25 of the water inlet device 21 assists the elastic sheet 13 at the top of the closed pipe 11 to seal and reset. In this way, when the elevation of the water inlet device 21 changes downward, the seal at the bottom of the closed pipe 11 is broken and connected to the water inlet 23, and the seal at the upper part is restored.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
