The existing suction pump equipment uses two suction pumps in parallel to realize the pumping and drainage inside the cylinder, but it cannot realize the reverse pumping and water injection outside the cylinder, and other equipment needs to be used for commutation, resulting in complex construction and high cost. Summary of the Utility Model

[0003] In view of the problems in the suction bucket sinking and grouting construction process, such as complex switching between the drainage mode and the water injection mode, large power loss, and difficult underwater leveling. The applicant proposes a submerged penetration conversion device, aiming to simplify the construction process, realize convenient waterway commutation through the conversion device, realize automatic leveling construction of the suction bucket sinking and grouting, and greatly shorten the construction period.

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] A submerged penetration conversion device includes a conversion pipeline, a telescopic mechanism, and a sealing piston. The conversion pipeline has at least three pipe parts, namely a two-way pipeline, a drainage pipeline, and a pumping pipeline. The two-way pipeline is used to connect with the suction bucket, and it pumps water from the suction bucket or injects water into the suction bucket. The drainage pipeline discharges the water sucked by the two-way pipeline from the suction bucket. The pumping pipeline sucks seawater to the two-way pipeline. The telescopic mechanism drives the sealing piston to move, so that the sealing piston fits between the water injection state and the drainage state. When the sealing piston is in the water injection state, it conducts the two-way pipeline and the pumping pipeline, and disconnects the drainage pipeline from the two-way pipeline and the pumping pipeline. When the sealing piston is in the drainage state, it conducts the two-way pipeline and the drainage pipeline, and disconnects the pumping pipeline from the two-way pipeline and the drainage pipeline.

When the sealing piston is located on the lumen of the drainage pipeline, the sealing piston is in the pumping state, and the passage between the drainage pipeline and the two-way pipeline and the pumping pipeline is disconnected. The pumping pipeline is conducted with the two-way pipeline through the opening. When the sealing piston leaves the lumen of the drainage pipeline and seals the opening, the sealing piston is in the drainage state, and the passage between the pumping pipeline and the two-way pipeline and the drainage pipeline is disconnected, and the drainage pipeline is conducted with the two-way pipeline.

The sealing piston 50 is in sealing sliding fit with the lumen of the drainage pipeline 12. When the sealing piston 50 is located on the lumen of the drainage pipeline 12, the sealing piston 50 is in the pumping state, and the passage between the drainage pipeline 12 and the two-way pipeline 13 and the pumping pipeline 10 is disconnected. The pumping pipeline 10 is conducted with the two-way pipeline 13 through the opening 100. When the sealing piston 50 leaves the lumen of the drainage pipeline 12 and seals the opening 100, the sealing piston 50 is in the drainage state, the passage between the pumping pipeline 10 and the two-way pipeline 13 and the drainage pipeline 12 is disconnected, and the drainage pipeline 12 is conducted with the two-way pipeline 13.

[0023] Continue to refer to Figure 2 and Figure 3 , in an embodiment of the present utility model, the sealing piston 50 has a first sealing surface 500 on the side facing the drainage pipeline 12, and the first sealing surface 500 is in sealing cooperation with the drainage pipeline 12. The sealing piston 50 has a second sealing surface 501 on the side facing the pumping pipeline 10, and the second sealing surface 501 is in sealing cooperation with the pumping pipeline 10.

[0024] Among them, the sealing piston 50 is a trapezoidal block structure, the shape and size of its first sealing surface 500 match the lumen of the drainage pipeline 12, and the shape and size of its second sealing surface 50 match the opening 100.

[0025] Continue to refer to Figure 1, in an embodiment of the present utility model, the telescopic mechanism 22 is a hydraulic press, which has a hydraulic shaft. The main body of the hydraulic press is located at the installation part of the conversion pipeline, and its hydraulic shaft passes through the through hole of the installation part and is connected to the sealing piston 50. Conventional sealing treatment is performed between the hydraulic shaft and the through hole of the installation part.

[0026] Continue to refer to Figure 2 and Figure 3 , in an embodiment of the present utility model, a flow sensor 20 is provided on the two-way pipeline 13 and a flow control valve 23 is provided on the two-way pipeline 13. The flow sensor 20 is used to monitor the flow rate passing through the two-way pipeline 13, and the flow control valve 23 is used to control the flow rate passing through the two-way pipeline 13.

[0027] In addition, the present utility model further includes a leveling controller 21 provided on the telescopic mechanism 22. The leveling controller 21 is electrically connected to the flow sensor 20, the flow control valve 23, the hydraulic mechanism 22, and the sensors on the sinking and penetration equipment respectively.

[0028] The present utility model is used in cooperation with a drainage pump and a water injection pump. Specifically, the pumping pipeline 10 is connected to the water injection pump, and the drainage pipeline 12 is connected to the drainage pump. The drainage pump is turned on during drainage, and the water injection pump is turned on during water injection.

[0029] The working principle of the present utility model is as follows:

[0030] The installation of the suction bucket jacket foundation is similar to the process of an inverted water cup entering the water. The sinking and penetration equipment is placed at the bottom of the water cup, and liquid is sucked or injected into the inside of the water cup to generate a pressure difference between the inside and the outside environment of the water cup, thereby realizing the sinking and floating process of the water cup.

[0031] The present utility model is installed inside the sinking and penetration equipment, and the sinking and penetration equipment is connected to the top of the suction bucket and is hoisted into the water together with the suction bucket. Before the suction bucket first enters the seabed, it sinks to the seabed by its own weight. After the suction bucket is stably inserted into the mud, start the present utility model, switch it to the drainage mode, and seal the pumping pipeline with the sealing piston; turn on the drainage pump, and the two-way pipeline starts to suck inside the barrel and discharge the seawater into the ocean through the drainage pipeline; then, the suction bucket continues to sink towards the mud surface. During the sinking process, the sensors on the sinking and penetration equipment constantly receive the sinking state of the barrel body and transmit it to the leveling controller. The sinking state is judged through the leveling control algorithm, and corresponding reactions are made through the flow control valve and the conversion device; if the suction bucket does not sink horizontally, stop drainage, switch to the water injection mode through the conversion device, seal the drainage pipeline, turn on the pumping pipeline and the water injection pump, and control the flow rate through the flow control valve to appropriately inject water into the barrel to correct the horizontal state of the barrel body. Then switch to the drainage mode and control the drainage flow rate to drain again; until the suction bucket sinks horizontally to the designated installation position, the sinking and penetration equipment automatically detaches from the suction bucket and floats up for recovery.

[0032] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
