Description

Technical Field

[0001] The utility model relates to the technical field of silt removal, in particular to an air jet device for reducing siltation in a harbor or dock based on a post-siltation re-emergence technology. Background Art

[0002] During the long-term operation of ports and docks, due to the siltation of sediment, it is necessary to dredge the water at regular intervals to ensure the safe operation of the ports and docks and avoid safety accidents. The post-siltation recovery technology is a new technology used for routine dredging.

[0003] The post-siltation recovery technology generally involves densely distributing high-pressure air outlets at the bottom of the water body, and disturbing the sediment by outputting high-pressure airflow, thereby suspending the deposited sediment, and taking away the sediment that floats to the surface with the help of the flow of tidal water. In actual application, this technology generally places a pipe at the bottom of the water body and releases high-pressure gas through the pipe, but the release of high-pressure gas from the pipe is not continuous. There is a time interval between the two gas releases. Therefore, during the interval, sediment will enter the gas release point on the pipe, causing blockage and affecting normal silt removal. Utility Model Content

[0007] As a preferred solution of the utility model, the masking structure includes a bracket arranged on the branch pipe, and two baffles are rotatably arranged on the bracket through a torsion spring, and the opposite sides of the two baffles are rotatably connected to the bracket.

[0010] As a preferred solution of the utility model, the air outlet is in the shape of an elongated strip, and the length direction of the elongated air outlet is parallel to the width direction of the arc-shaped diverter plate.

[0011] As a preferred solution of the utility model, the spraying direction of the nozzle is inclined downward by 45 degrees along the horizontal direction.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0022] like Figure 1 and Figure 2 As shown, the utility model provides a jet device for reducing siltation in harbors and docks based on post-siltation re-emergence technology, comprising a plurality of gas modules arranged in a straight line in sequence below the harbor and the dock, each gas module comprising a main pipeline 1 and a plurality of branch pipelines 2 and a frame 5, and the plurality of branch pipelines 2 are vertically connected to the main pipeline 1, the main pipeline 1 and the plurality of branch pipelines 2 are installed on the frame 5, the main pipeline 1 is connected to an air compressor, and each branch pipeline 2 is provided with a plurality of nozzles 3 and a plurality of masking structures 4 at equal intervals along its axial direction, and the plurality of masking structures 4 are respectively used to shield the mouths of the nozzles 3 corresponding thereto, and are opened by the airflow ejected from the nozzles 3.

[0023] When the present invention is in use, compressed air is delivered to the main pipeline 1 of the gas module through an air compressor. The compressed air passes through the main pipeline 1 and multiple branch pipelines 2 in sequence and is sprayed into the water through a nozzle 3, thereby disturbing the silt deposited in the harbor and the dock, so as to clean the silt and reduce the silt accumulation. The normal operation of the harbor and the dock will not be disturbed during the dredging. The frame 5 is used to fix the main pipeline 1 and multiple branch pipelines 2 underwater.

[0024] When the air compressor is not working, that is, the nozzle 3 is not spraying high-pressure gas, the shielding structure 4 is in contact with the mouth of the nozzle 3, preventing mud and sand in the water from entering the nozzle 3 and entering the branch pipe 2 through the nozzle 3, thereby avoiding the problem of blockage of the nozzle 3 and the problem of mud and sand accumulating inside the branch pipe 2, which causes the gas to impact the mud in the branch pipe 2 and block the nozzle 3 when the air compressor is working.

[0025] The shielding structure 4 includes a bracket 401 disposed on the branch pipe 2 , and two baffles 402 are rotatably disposed on the bracket 401 through a torsion spring, and the opposite sides of the two baffles 402 are rotatably connected to the bracket 401 .

[0026] When the air compressor is not working, the nozzle 3 does not spray gas, and the two baffles 402 are pressed against the mouth of the nozzle 3 under the elastic force of the torsion spring, thereby jointly restricting the mud and sand in the water from entering the nozzle 3 and preventing the nozzle 3 from being blocked.

[0027] When the air compressor is working, the nozzle 3 sprays high-pressure gas, and the two baffles 402 are impacted by the gas and rotate in the direction away from the nozzle 3, so that the gas sprayed by the nozzle 3 can be normally sprayed into the water and disturb the silt, so that the silt is suspended and floats to the water surface and slides away with the tide, thereby clearing the silt deposited under the harbor and the dock. At this time, the torsion spring is in a deformed state, so that the baffle 402 can be reset to the mouth of the nozzle 3 under the elastic force of the torsion spring when it is not impacted by the gas.

[0028] The bracket 401 is used to support and install the baffle 402 .

[0029] Furthermore, the torsion spring should be arranged in a cylindrical groove on the bracket 401, and the baffle 402 is rotatably connected to the cylindrical groove through the shaft, the torsion spring is sleeved on the shaft, and a sealing ring or other sealing method is sleeved on the shaft to seal the cylindrical groove to prevent the torsion spring from being corroded.

[0030] A square frame 404 is provided on the bracket 401 through multiple pillars 403, and two arc-shaped diverter plates 405 are provided on the square frame 404, and one end of the two arc-shaped diverter plates 405 are connected in a herringbone shape, and each arc-shaped diverter plate 405 is provided with multiple air ports 406, and the baffle 402 is located between the square frame 404 and the nozzle 3.

[0031] When the nozzle 3 sprays gas, the two baffles 402 rotate in a direction away from the nozzle 3, and the airflow sprayed from the nozzle 3 is separated by two arc-shaped splitter plates 405 that together form a herringbone shape to form two airflows. The two airflows flow along the arc-shaped splitter plates 405 and are sprayed out through multiple air ports 406, thereby expanding the spray range of the nozzle 3 and improving the disturbance range and disturbance effect of the nozzle 3 on the sediment.

[0032] The support pillars 403 ensure a certain distance between the square frame 404 and the baffle plate 402 , so as to prevent the baffle plate 402 from interfering with the square frame 404 and the arc-shaped diverter plate 405 when rotating.

[0033] The edge of the baffle plate 402 that contacts the nozzle 3 is perpendicular to the arc-shaped diverter plate 405 .

[0034] The gas passing through the two baffles 402 will be distributed and move along the edges of the baffles 402, making the range of the gas wider. At this time, the gas is cut into two larger volumes by the edge of the arc-shaped diverter plate 405, which is more convenient to flow along the arc-shaped diverter plate 405 and pass through multiple gas ports 406.

[0035] The air opening 406 is in a long strip shape, and the length direction of the air opening 406 is parallel to the width direction of the arc-shaped splitter plate 405 .

[0036] The long gas opening 406 is more convenient for gas to pass through.

[0037] The spraying direction of the nozzle 3 is tilted downward by 45 degrees along the horizontal direction, thereby improving the disturbing effect of the gas sprayed by the nozzle 3 on the deposited silt.

[0038] The embodiments and / or implementation methods described above are only used to illustrate the preferred embodiments and / or implementation methods for realizing the technology of the utility model, and are not intended to limit the implementation methods of the technology of the utility model in any form. Any technical personnel in this field may make slight changes or modifications to other equivalent embodiments without departing from the scope of the technical means disclosed in the content of the utility model, but they should still be regarded as technologies or embodiments that are essentially the same as the utility model.

The description of the above embodiments is only used to help understand the method and its core ideas of this application. The above is only the preferred implementation method of this application. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of this application, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the scope of protection of this application.
