[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] Reference below Figure 1-Figure 2 The scouring and silting system 100 according to an embodiment of the present invention is described, and the scouring and silting system 100 is used in a lock 20, and the lock 20 is provided with a gate 10. The scouring and silting system 100 is mainly used in ship locks or water diversion channels, but can also be used in any river channel with a gate that is prone to siltation.

[0027] like Figure 1 , Figure 2 As shown, a silt flushing system 100 for a gate 20 according to an embodiment of the present invention comprises: an inlet pipe 30, an outlet pipe 40 and a sensor 50; the inlet pipe 30 is formed with a water inlet 31 suitable for water diversion, and the water inlet 31 is arranged upstream of the gate plate 10; the outlet pipe 40 is connected to the inlet pipe 30, and the outlet pipe 40 is formed with a water outlet 41 suitable for silt flushing, and the water outlet 41 is arranged downstream of the gate plate 10 and located at the bottom of the gate 20; the sensor 50 is arranged in the gate 20, and the sensor 50 is used to monitor the silt distribution in the gate 20 to adjust the water output of the outlet 41 according to the silt distribution.

[0028] According to the silting system 100 of the embodiment of the present invention, Figure 1 As shown, the water inlet 31 is arranged upstream of the gate 10, and the water outlet 41 is arranged downstream of the gate 10. Since the upstream water level L1 is higher than the downstream water level L2 of the gate 10, there is a natural water pressure difference between the water inlet 31 and the water outlet 41, and the smaller the opening of the gate 10, the greater the water pressure difference; the water inlet pipeline 30 is connected to the water outlet pipeline 40, and the water pressure difference between the water inlet 31 and the water outlet 41 can automatically realize the silt flushing from the upstream water inlet 31 to the downstream water outlet 41. The sensor 50 is arranged in the gate 20 to monitor the distribution of the depth and width of the silt at the bottom of the gate 20 in real time within the monitoring range, and the water output of the water outlet pipeline 40 is adjusted according to the monitoring results, which can selectively change the flushing effect on the silt.

[0029] According to the silt flushing system 100 of the embodiment of the present invention, the naturally existing water pressure difference between the water inlet 31 and the water outlet 41 can be used to realize continuous automatic water diversion and silt flushing to avoid silt accumulation; the water output is adjusted according to the result of the sensor 50 monitoring the silt distribution, which can ensure efficient silt flushing and improve the silt flushing effect; the silt flushing system 100 of this embodiment can be automatically completed at the bottom of the gate 20 without the need for surface operations, without affecting the normal operation of the ship lock or the water diversion channel, and has economic benefits.

[0030] According to some embodiments of the present invention, the position of the water inlet 31 of the water inlet pipeline 30 is higher than the position of the water outlet 41 of the water outlet pipeline 40. The water outlet 41 is set at the silt accumulation place downstream of the gate plate 10. If there is silt accumulation at the height position of the water outlet 41, there is inevitably the possibility of silt accumulation upstream. If the height of the water inlet 31 is not enough, the water flow will carry part of the silt into the silt flushing system 100 during water diversion, resulting in poor silt flushing effect and even aggravating the degree of siltation. In some embodiments, such as Figure 1 As shown, the outlet pipe 40 is formed with a pipe section that is partially bent toward the water surface. By setting the pipe section that is bent upward in the outlet pipe 40, the height of the water inlet 31 can be raised to ensure that the position of the water inlet 31 is higher than the position of the water outlet 41, and the water without sediment is taken to be diverted to the downstream for silt flushing, thereby ensuring the silt flushing effect. It should be noted that the length of the bent pipe section can be determined according to the sediment distribution monitoring results, so that the height of the water inlet 31 is higher than the sediment distribution layer height and lower than the underwater working surface when the ship lock or the water diversion channel is in operation. Furthermore, the bent pipe section can also be set as an adjustable pipe section, which can be adjusted according to actual conditions when the silt flushing system 100 is in operation.

[0031] According to some embodiments of the present invention, the silt flushing system 100 further includes a water pump 60 , the water inlet end of the water pump 60 is connected to the water inlet pipeline 30 , the water outlet end of the water pump 60 is connected to the water outlet pipeline 40 , and the water pump 60 is used to adjust the water output of the water outlet pipeline 40 .

[0032] The water pump 60 is connected to the water inlet pipeline 30 and the water outlet pipeline 40. The upstream water flows to the water outlet 41 through the water inlet pipeline 30, the water pump 60 and the water outlet pipeline 40 to flush the silt. The water pump 60 can use mechanical energy to convert low-pressure water into high-pressure water, that is, to increase the pressure of the water flowing to the water inlet end of the water pump through the water inlet pipeline 30, so that the water flow velocity in the water outlet pipeline 40 is accelerated, the water output of the water outlet 41 is increased, the impact force on the silt is increased, and the flushing effect is improved; at the same time, the water pump 60 is set at the bottom of the gate 20 with the water inlet pipeline 30 and the water outlet pipeline 40, and can be electrically controlled, without the need for water entry operation, and does not affect navigation and irrigation. In this embodiment, when the water pressure difference between the water inlet 31 and the water outlet 41 is insufficient or in the dry season, the water pump 60 is used to assist in pumping water to flush the silt, which can ensure that the flushing work continues and avoid silt accumulation.

[0033] According to some embodiments of the present invention, the water outlet pipeline 40 includes: a main pipeline 42 and a branch pipeline 43, the main pipeline 42 is connected to the water inlet pipeline 30; the branch pipelines 43 are constructed in multiples and are respectively connected to the main pipeline 42, and each branch pipeline 43 is formed with at least one water outlet 41.

[0034] The outlet pipe 40 is constructed as a branch structure composed of a main pipe 42 and a branch pipe 43. Water flows through the main pipe 42 and is divided into each branch pipe 43. Water is discharged from the outlet of each branch pipe 43 to impact the nearby silt. Multiple branch pipes 43 can be dispersedly arranged on the bottom of the water rich in silt, which can disperse the impact force on the silt, expand the scope of silt flushing, and reduce dead corners that cannot be flushed.

[0035] According to some embodiments of the present invention, the silt flushing system further includes: a main water outlet valve 44 and a branch water outlet valve 45. The main water outlet valve 44 is arranged on the main pipe 42 and is used to adjust the opening of the main pipe 42; the branch water outlet valve 45 is constructed to be a plurality of valves corresponding one to one to the branch pipes 43, and each branch water outlet valve 45 is used to control the opening of the corresponding branch pipe 43.

[0036] In this embodiment, since each branch outlet valve 45 controls the opening of the corresponding branch pipeline 43; the opening of each branch pipeline 43 can be independently controlled, and only opening a certain or part of the branch pipeline 43 can make the water outlet concentrated to achieve the corresponding local area silt flushing, and the impact force of this part of the water outlet is large, and the silt flushing effect is good. Based on this, according to the monitoring results of the sensor 50, the silt flushing system 100 of this embodiment is suitable for reasonably arranging the opening and closing sequence and the number of opening and closing of the branch pipeline 43 according to the distribution of silt and the degree of siltation. For example, the branch pipeline 43 with a higher degree of siltation is opened first to concentrate the silt flushing, avoid the continued accumulation of silt, and reduce the difficulty of silt removal. At the same time, the branch pipelines 43 can cooperate with each other in time and space. Opening each branch pipeline 43 in sequence can make the water outlets of each route interact with each other to increase the turbulent effect, impact and stir the silt to make it suspended to avoid sinking, and it is easier to completely flush the silt.

[0037] Furthermore, the main outlet valve 44 adjusts the opening of the main line 42, and can control the entire silt flushing system 100 to start or stop silting, so as to meet the different requirements of the normal operation of the ship lock or the water diversion channel. At the same time, the silt flushing mode can be switched by controlling the opening of the main line 42 through the main outlet valve 44: when the main line 42 is always open, continuous silt flushing is performed using the natural pressure difference and the assistance of the water pump; when the main line 42 is opened and closed regularly, regular silt flushing is performed.

[0038] According to some embodiments of the present invention, each branch pipe 43 is formed with a plurality of water outlets 41, and the plurality of water outlets 41 are arranged on the downstream side of the branch pipe 43. The plurality of water outlets 41 can cover more siltation ranges and reduce dead corners for silt flushing; the water outlets 41 are arranged on the downstream side to spray water in a directional manner, which makes it easier to flush the silt downstream.

[0039] According to some embodiments of the present invention, the water outlets 41 of two adjacent groups of branch pipes 43 are staggered. Figure 2 As shown, the staggered water outlets 41 can make the water flow more uniform during the flushing process and reduce the possibility of local silt accumulation; at the same time, the adjacent branch pipes 43 cooperate with each other to increase the turbulence effect when the water flows out, impact and stir the silt to suspend it and avoid sinking to the bottom, making it easier to completely flush away the silt.

[0040] According to some embodiments of the present invention, multiple groups of sensors 50 are provided and dispersedly arranged downstream of the water outlet 41. The monitoring range of the sensor 50 is limited, and the accuracy of the sensor 50 may be affected by the dynamic changes of water flow and the obstruction of sediment. The provision of multiple groups of sensors 50 can expand the monitoring range, and some monitoring results can be mutually verified, so that the monitoring error can be reduced, the reliability of the silt flushing system 100 can be improved, and the silt flushing effect can be ensured.

[0041] According to some embodiments of the present invention, the gate plate 10 is movably arranged and a bypass groove for avoiding the water inlet pipeline 30 is formed on the gate plate 10. The bypass groove provided on the gate plate 10 enables the water inlet pipeline 30 to pass through the gate plate 10 so that the water inlet 31 extends to the upstream, and the gate plate 10 and the water inlet pipeline 30 are separated from each other, which does not affect the opening and closing of the gate plate 10, and the silt flushing system 100 can be more easily arranged at the bottom of the gate 20.

[0042] According to some embodiments of the present invention, at least a portion of the water inlet pipeline 30 passes through the gate wall 70 of the gate channel 20 and extends upstream of the gate plate 10. Figure 2 As shown, the gate wall 70 refers to the wall on both sides of the gate channel 20 for installing the gate plate 10. The water inlet pipe 30 passes through the gate wall 70 and can bypass the gate plate 10 without affecting the structure and movement of the gate plate 10, so that the water inlet 31 is set upstream of the gate plate 10. At the same time, the gate wall 70 can limit the water inlet pipe 30, fix the position of the water inlet pipe 30, and increase the stability of the silting system 100 in the gate channel 20.

[0043] According to some embodiments of the present invention, the water inlet pipeline 30 is provided with a water inlet valve 32, which can control the opening of the water inlet pipeline 30 to adjust the water inlet amount, and close the water inlet pipeline 30 to suspend water diversion when necessary.

[0044] According to some embodiments of the present invention, the silting system 100 further includes a control system 80, which is connected to the sensor 50, the water pump 60, the water inlet valve 32, the main outlet valve 44 and each branch outlet valve 45. The silting system 100 is provided with an automatic analysis and decision-making system, which is suitable for analyzing and making decisions based on the data signal monitored in real time by the sensor 50, and instructing the water pump 60, the main outlet valve 44 and each branch outlet valve 45 to operate to adjust the water output. By setting the control system 80, automatic regulation and automatic silting can be achieved, the automation degree of the silting system 100 can be improved, the workload of the operator can be reduced, and the application scope of the silting system 100 can be expanded.
