Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of silt removal, in particular to a water spraying device for reducing siltation in a harbor or dock based on a post-siltation re-emergence technology. Background Art
[0002] Due to the environment in which they are located, a lot of silt will accumulate underneath the harbor and the dock after a long period of operation. When the silt accumulates to a certain amount, it will affect the normal navigation of ships and other objects, causing the harbor and the dock to be unable to operate normally. Therefore, it is necessary to regularly clean the silt accumulated under the harbor and the dock. The post-siltation recovery technology is a technology used to clean up the silt.
[0003] The post-siltation re-emergence technology is to set up pipes at the bottom of the water, and transmit high-pressure water flow through the pipes, and then spray the high-pressure water flow into the water through nozzles to disturb the sediment on the bottom of the water so that the sediment is re-suspended, and then floats to the surface and flows away with the tide to complete the removal of silt under the harbor and the dock. However, when silting is carried out in this way, the spray direction of the high-pressure water flow is in the same direction, generally obliquely downward to impact the deposited sediment, which will cause the sediment to actually be subjected to forces in two directions. Part of the impact force impacts the sediment to suspend it, and the other part of the impact force impacts the sediment to make the sedimentation more solid. It is difficult to suspend all the sediment around the impact point of the high-pressure water flow, and the disturbance effect on the sediment is poor. Utility Model Content

[0024] 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.
[0025] 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.
[0026] like Figures 1 to 5 As shown, the utility model provides a water spraying device for reducing siltation in a harbor and a dock based on the post-siltation re-emergence technology, comprising a plurality of impact modules arranged in sequence along a straight line, each impact module comprising a main pipe 1 and a plurality of branch pipes 2 connected to the main pipe 1, and a frame 3 for fixing the main pipe 1 and the plurality of branch pipes 2 on the bottom of the water, and the main pipe 1 is connected to a pump body for conveying high-pressure water flow, and a plurality of diversion type nozzles 4 are arranged on each branch pipe 2 along its own axial direction at equal intervals, and the diversion type nozzle 4 has a plurality of water spraying ports and sprays high-pressure water in a plurality of directions, and one of the water spraying ports of the diversion type nozzle 4 contacts the silt and sprays water flow in a horizontal direction.
[0027] In actual application, the utility model fixes the main pipeline 1 and multiple branch pipelines 2 under the harbor and the dock through the frame 3, and transmits high-pressure water flow through the pump body, so that the high-pressure water flow passes through the main pipeline 1 and the branch pipeline 2 in turn and is sprayed to the silt through the diverter nozzle 4, and the silt under the harbor and the dock is disturbed by the impact force of the high-pressure water flow, so that the deposited silt is re-suspended and floats to the water surface under the action of buoyancy to follow the movement of the water flow, thereby clearing the silt under the harbor and the dock, and multiple impact modules are arranged along a straight line to form a whole silt clearing belt to ensure the silt clearing effect.
[0028] When the high-pressure water flow is sprayed through the diverter nozzle 4, it will be sprayed out from multiple water nozzles. Therefore, the high-pressure water flow has multiple impact directions on the silt, making it easier for the silt to be suspended after being impacted, and the horizontal water nozzles are in contact with the silt, so that the sprayed high-pressure water flow can impact the silt in the horizontal direction, which can effectively improve the impact disturbance effect on the silt and improve the dredging effect on the silt under the harbor and the dock.
[0029] The split-flow nozzle 4 includes a first pipe 401 obliquely arranged on the branch pipe 2, a first nozzle 402 is arranged at the end of the first pipe 401, a second pipe 403 is arranged on the first pipe 401, and the second pipe 403 is connected to the second nozzle 404, and a one-way pressure switch 410 is arranged in the first pipe 401.
[0030] The height of the second nozzle 404 is less than that of the first nozzle 402 and contacts the siltation. The second nozzle 404 sprays in a horizontal direction, and the one-way pressure switch 410 is located between the first nozzle 402 and the position on the first pipeline 401 connecting to the second pipeline 403 .
[0031] When the high-pressure water flow passes through the diverter nozzle 4, it first passes through the first pipe 401, then enters the second pipe 403 from the first pipe 401, and is finally ejected through the second nozzle 404 to disturb the sludge. The passage in the first pipe 401 leading to the first nozzle 402 is blocked by the one-way pressure switch 410. This method is suitable for situations where silt accumulation under the harbor and dock is not serious. The high-pressure water flow ejected horizontally by the second nozzle 404 can effectively disturb the sludge to float upward.
[0032] When the silt accumulation under the harbor and the dock is serious, in order to further increase the pressure of the high-pressure water flow, it is necessary to increase the impact disturbance effect of the second nozzle 404 on the silt to suspend the silt. The one-way pressure switch 410 is opened by the pressure of the high-pressure water flow, so that the first nozzle 402 impacts the silt in an oblique downward direction, so that the silt is impacted in two directions, thereby improving the disturbance effect on the silt and ensuring that the accumulated silt can be effectively disturbed and suspended.
[0033] The second pipe 403 includes a fixed pipe 405 vertically arranged on the first pipe 401 , a movable pipe 406 is slidably and sealedly sleeved inside the fixed pipe 405 , and a plurality of springs 407 connected to the outer wall of the movable pipe 406 are arranged on the inner wall of the fixed pipe 405 .
[0034] In order to ensure that the second nozzle 404 can effectively contact the silt, and to avoid the silt from burying the second nozzle 404 after deposition, thereby affecting the impact disturbance effect on the silt or causing the second nozzle 404 to be blocked, when dredging is not performed, that is, when high-pressure water is not sprayed, under the elastic force of multiple springs 407, most of the movable tube 406 is located in the fixed pipe 405, so that the second nozzle 404 is away from the accumulated silt, which can effectively prevent the silt from burying the second nozzle 404.
[0035] When silt removal is required, that is, high-pressure water jetting is required, under the impact of the high-pressure water jetting, the movable pipe 406 moves downward along the fixed pipe 405 until the second nozzle 404 is against the accumulated silt. At this time, the accumulated silt supports the second nozzle 404 and the bottom of the movable pipe 406, so that the high-pressure water jetted by the second nozzle 404 continuously impacts the accumulated silt in the horizontal direction, which has a better impact disturbance effect than impacting the silt obliquely downward, because the accumulated silt will not be pressed down. Multiple springs 407 are compressed, and the springs 407 are used to assist the movable pipe 406 to move upward and reset, and the sealed environment between the inner wall of the fixed pipe 405 and the outer wall of the movable pipe 406 prevents water from the harbor and the dock from entering and eroding the spring 407.
[0036] Furthermore, the movable pipe 406 is sleeved on the bottom of the fixed pipe 405 and moves up and down in the vertical direction, which can also effectively prevent sediment from accumulating between the fixed pipe 405 and the movable pipe 406 .
[0037] The inner wall of the fixed tube 405 is provided with a plurality of mounting grooves 408 , the outer wall of the movable tube 406 is provided with a plurality of sliders 409 , and the plurality of sliders 409 are respectively slidably connected in the plurality of mounting grooves 408 , and the two ends of the plurality of springs 407 are respectively connected to the inner wall of one of the mounting grooves 408 and one of the sliders 409 .
[0038] The spring 407 and the slider 409 are installed through the installation groove 408, so that a closed installation space is formed between the movable tube 406 and the fixed tube 405 to install the spring 407, avoiding the problem of the spring 407 being easily damaged by being exposed to water and extending the service life.
[0039] When the movable tube 406 moves downward, it drives the slider 409 to compress the spring 407 downward.
[0040] The one-way pressure switch 410 includes a sealing slide 411 that is slidably and sealingly connected to the first pipe 401, a support plate 413 that is connected to the inner wall of the first pipe 401 through multiple connecting rods 412, and multiple limit blocks 414. The sealing slide 411 is located between the limit block 414 and the first nozzle 402. Two mutually repelling magnets 415 are provided on the opposite side walls of the sealing slide 411 and the support plate 413. Multiple water grooves 416 are provided on the inner wall of the first pipe 401 along its own axial direction. When the side of the sealing slide 411 that is away from the first nozzle 402 abuts against the multiple limit blocks 414, the multiple water grooves 416 are located between the sealing slide 411 and the first nozzle 402.
[0041] When the one-way pressure switch 410 is subjected to the impact force of the water flow, the sealing slide 411 slides toward the support plate 413 under the impact of the water flow. When the pressure of the water flow increases to a certain level, the sealing slide 411 moves to the position between the two inner walls of the water groove 416, that is, the two ends of the water groove 416 are respectively located on both sides of the sealing slide 411. At this time, the water flow can flow through the water groove 416 to the other side of the sealing slide 411, and be sprayed through the first nozzle 402 to disturb the accumulated silt.
[0042] When there is no impact pressure of the water flow or the impact pressure of the water flow is small, since the two magnets 415 repel each other, that is, the opposite sides of the two magnets 415 have the same magnetic pole, the support plate 413 provides stable support for one of the magnets 415 through the connecting rod 412, so that the magnet 415 on the sealing slide 411 provides support for the sealing slide 411 under the magnetic repulsion of the other magnet 415, so that when the second nozzle 404 is able to impact and disturb the sludge alone, the channel leading to the first nozzle 402 in the first pipe 401 is closed.
[0043] Furthermore, due to the magnetic repulsion of the two magnets 415 , the sealing slide plate 411 can automatically reset to seal the passage in the first pipe 401 leading to the first nozzle 402 .
[0044] The two opposite side walls of the sealing slide plate 411 and the support plate 413 are jointly provided with a bellows 417 , and the two ends of the bellows 417 are respectively sleeved on the outer sides of the two magnets 415 .
[0045] The bellows 417 can effectively prevent water from coming into contact with the two magnets 415 and prevent the magnets 415 from being corroded by the external environment. The bellows 417 can shrink or stretch as the sealing slide 411 moves, avoiding interference with the movement of the sealing slide 411.
[0046] Furthermore, the bellows 417 may also be other hoses that can be extended and retracted to avoid interference with the sealing slide plate 411 .

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.
