Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of uniform sand cleaning device for cylinder type foundation, and particularly relates to a uniform sand cleaning device for offshore wind power composite cylinder type foundation. BACKGROUND

[0002] For example, CN120042231A discloses an offshore wind power composite cylinder type foundation with an overturning reset function, which hammers the upturned end of the composite cylinder type foundation by using a hammering assembly and extracts seawater or silt or sand in the interior of the cylinder type foundation by using a branch extraction pipe, so as to realize self-rescue of the offshore wind power after tilting.

[0003] However, the branch extraction pipe is arranged at only one corner of the outer side of the composite cylinder type foundation, so that the accumulated silt or sand on the surface of the seabed is difficult to clean during the sinking process of the entire composite cylinder type foundation into the seabed, and the sinking of the composite cylinder type foundation is easily blocked and tilted. Similarly, when the composite cylinder type foundation is tilted after installation, in addition to the tilting of the composite cylinder type foundation caused by the accumulation of internal silt, the offshore wind power is also tilted by the influence of external wind and water flow. At this time, the internal silt of the composite cylinder type foundation will accumulate in the opposite direction of the tilting end due to the pressure of the inner wall of the composite cylinder type foundation. At this time, the branch extraction pipe is also difficult to discharge, and can only rely on the slow hammering of the hammering assembly. SUMMARY

[0004] Therefore, it is necessary to provide a uniform sand cleaning device for offshore wind power composite cylinder type foundation in view of the above technical problem of single extraction position of the branch extraction pipe.

[0005] In order to achieve the above purpose, the present application provides a uniform sand cleaning device for offshore wind power composite cylinder type foundation, which comprises: A foundation cylinder comprises a plurality of extraction pipes, the plurality of extraction pipes are uniformly installed on the top of the foundation cylinder, a branch extraction pipe is installed on the foundation cylinder, the plurality of extraction pipes are communicated with the branch extraction pipe through an annular pipe, a valve is installed on the extraction pipe, the bottom of the extraction pipe is communicated with the inner wall of the foundation cylinder through an enlarged extraction mechanism, and the extraction pipe is sealingly connected with the foundation cylinder. A monitoring mechanism comprises a transparent shell, the transparent shell is sealingly and fixedly installed on the foundation cylinder, and a monitoring head is installed in the transparent shell.

[0006] By adopting the technical scheme, in the process of lowering the foundation cylinder, the monitoring mechanism is lowered, the monitoring head in the transparent shell can start to observe whether there is silt accumulation under the foundation cylinder when the foundation cylinder is still at a high position, when there is accumulation at a certain place of the seabed, the valve on the extraction pipe near the accumulation on the foundation cylinder can be opened, so that the accumulation can be extracted and discharged from the extraction pipe, so that the foundation cylinder can be smoothly sunk into the seabed. Since the number of extraction pipes cannot be set too much and the interval between the extraction pipes is set, when the accumulation is between two extraction pipes, the two extraction pipes can be opened, so that the accumulation is extracted and cleaned twice and other places are extracted and cleaned once, so that the purpose of uniform cleaning is also achieved. When the foundation cylinder is tilted after installation, the monitoring head in the monitoring mechanism can also be used for observation. At this time, since the distance between the top wall in the foundation cylinder and the seabed is small, the monitoring head can only observe whether there is silt and sludge accumulation in a part of the seabed. If there is no accumulation at the detection position, the extraction pipe on the opposite side of the monitoring mechanism can be opened for extraction, and the extracted material can be observed. If there is no sludge and silt, the opened extraction pipe is closed, and the extraction pipe at the higher position of the tilted foundation cylinder is opened to extract water outward, and the self-rescue device on the foundation cylinder can be opened synchronously to cooperate with self-rescue. The enlarged extraction mechanism can enlarge the extraction range of the extraction pipe to avoid single pipe setting and only extract the silt at the bottom of the extraction pipe, which can cause the flatness of the seabed to be poor. The sealed and fixed installation of the transparent shell and the foundation cylinder ensures that the negative pressure can still be formed in the foundation cylinder when the extraction pipe extracts outward, so as to facilitate the resetting and sinking of the foundation cylinder. The silt extracted by the extraction pipe is transported to the branch extraction pipe through the annular pipe, and the branch extraction pipe plays a role of communication with the outside.

[0007] Optionally, the machine frame is further provided, the plurality of foundation cylinders are evenly arranged on the machine frame, a main extraction pipe is arranged on the machine frame, output ends of the plurality of branch extraction pipes are located in the main extraction pipe, a valve structure is arranged on the output end of the branch extraction pipe, a water inlet pipe for supplying water to the branch extraction pipe is arranged on the main extraction pipe, the enlarged extraction mechanism comprises a rotating head, the rotating head is rotatably arranged at the bottom of the extraction pipe, a plurality of installation grooves are arranged in the rotating head, a plurality of adjusting plates are hingedly arranged in the installation grooves, a plurality of inclined through holes are arranged on the adjusting plates, and an inclined extraction opening is arranged at the bottom of the rotating head.

[0008] When a certain foundation cylinder needs to discharge materials such as seawater and silt, the corresponding valve structure can be opened, and the discharge port on the main suction pipe can suck outwards through the suction pump, while the water inlet pipe connected with the water inlet pump can cooperate with the water inlet to dilute the materials, so that the materials can be smoothly discharged; when the materials are sucked out, the adjusting plate will be pushed by the materials to rotate into the installation groove, which will not affect the discharge of the materials, and when the extraction pipe does not extract, the adjusting plate can be deflected downward due to its own gravity, at this time, water can be injected into the branch extraction pipe through the water inlet pipe, and the adjusting plate in the extraction pipe with the opened valve can be rotated after being impacted by the water pressure on the inclined through hole, so that the adjusting plate can drive the rotating head and the inclined extraction port to rotate, thereby repeatedly extracting the materials and injecting water into the foundation cylinder, so that the inclined extraction port can continuously rotate, and the seabed after extraction by the extraction pipe can be more flat; the installation groove can be fixedly installed with a pad, so as to avoid the adjusting plate from being deflected and falling when it is in a vertical state and no longer stops extraction.

[0009] Optionally, the enlarged extraction mechanism further comprises a rotating head two, which is rotatably installed at the bottom of the extraction pipe, and a plurality of inclined short plates are installed in the rotating head two, and an inclined extraction port two is installed at the bottom of the rotating head two.

[0010] By adopting the above technical scheme, when the extraction pipe is extracting, the materials can be given a certain thrust by the inclined surface of the inclined short plate when passing through the inclined short plate, so that the inclined short plate can drive the rotating head two and the inclined extraction port two to continuously rotate during the extraction process.

[0011] Optionally, the enlarged extraction mechanism further comprises a plurality of inclined inlets, which are arranged on the foundation cylinder, and the ends of the plurality of inclined inlets close to each other are located at the bottom of the extraction pipe.

[0012] By adopting the above technical scheme, when the extraction pipe is extracting, the materials can pass through the plurality of inclined inlets and enter, and through the arrangement of the inclined inlets, the purpose of uniformly extracting the materials on the seabed by the extraction pipe under the action of the enlarged extraction mechanism is achieved.

[0013] Optionally, the branch extraction pipe is made of transparent material, and a colored observation plate is installed on the rotating head.

[0014] By adopting the above technical scheme, when water is injected into the extraction pipe through the water inlet pipe, the rotation position of the colored observation plate can be observed, and the water injection can be stopped in advance according to the inertial force, so that the input end of the inclined extraction port can stop at the required position, that is, directly opposite to the accumulated materials, thereby achieving the purpose of accurately extracting the accumulated materials.

[0015] Optionally, the inclined extraction port or the inclined extraction port two is located inside the top wall of the foundation cylinder.

[0016] By adopting the technical scheme, the inclined suction port or the second inclined suction port will not collide with the seabed during the process of turning and sinking with the foundation cylinder.

[0017] Optionally, the transparent shell is internally provided with a lighting device.

[0018] By adopting the technical scheme, the lighting device can be turned on to provide illumination when the monitoring head is working, so that the staff can observe the accumulation situation, and the monitoring head and the lighting device can be provided with power and connected with the external signal processor.

[0019] Optionally, the adjusting plate is provided with a chamfer facilitating mutual abutment of adjacent adjusting plates.

[0020] By adopting the technical scheme, when the adjusting plate is deflected and lowered due to its own gravity, the adjacent adjusting plates can be kept in a gap-fitted or abutted state, so that most of the water flow can pass through the inclined adjusting plate, improving the self-rotating adjusting efficiency.

[0021] Optionally, one side of the inclined short plate facing the interior of the foundation cylinder is provided with a wear-resistant layer.

[0022] By adopting the technical scheme, the wear of the inclined short plate by the silt during the whole suction work of the suction pipe is reduced, improving the service life.

[0023] Optionally, the rack is provided with an inclination sensor.

[0024] By adopting the technical scheme, when the rack is sunk together with the foundation cylinder or is inclined after installation, the inclination sensor cooperates with the monitoring mechanism to transmit signals, accurately determining the inclination angle and direction.

[0025] The technical scheme has at least the following beneficial effects: 1. By installing multiple suction pipes on the foundation cylinder and cooperating with the monitoring mechanism, the position of the accumulated material on the seabed can be determined during the sinking and post-installation inclination of the foundation cylinder, and the accumulated material can be accurately cleaned, thereby facilitating the sinking of the foundation cylinder and the overall resetting of the offshore wind power. 2. By expanding the suction mechanism in multiple ways, the suction pipe can uniformly extract the accumulated material on the seabed, avoiding the uneven seabed caused by straight pipe extraction. 3. By cooperating the colored observation plate with the inclined suction port, the suction pipe can cooperate with the monitoring mechanism to accurately position and extract the accumulated material on the seabed.
