Specific implementation

[0027] The technical scheme in the utility model embodiment will be clearly and completely described below with reference to the drawings in the utility model embodiment.

[0028] Referring to Figures 1-3 , the utility model provides an embodiment: a kind of fixed type dredging device based on pump station water intake, including dam body 12, dam body 12 top is equipped with maintenance assembly, and maintenance assembly can conveniently provide device maintenance convenience for staff.Dam body 12 bottom is equipped with water intake 9, water intake 9 inside is equipped with jet pipeline 8, multiple jet assemblies 2 are installed on the outside of jet pipeline 8, jet pipeline 8 is divided into two branch pipes, and multiple jet assemblies 2 are distributed on each branch pipe, to ensure that the silt accumulated in water intake 9 can be scattered and suspended under high-pressure water flow.Water intake 9 inner wall is fixedly connected with water filling pump 10, and the model of water filling pump 10 is NAUTILUS series submersible pump, can be directly pumped and discharged to the water body containing silt.Water intake 9 top is equipped with ultrasonic sludge interface meter 3, and the model of ultrasonic sludge interface meter 3 is joint SIN-JFC ultrasonic sludge interface meter, can real-time detect the thickness of silt accumulated in water intake 9.Dam body 12 bottom wall one side is fixedly installed with sand pump 1, and the model of sand pump 1 is WQ type submersible pump, adopts automatic coupling base, is fixed in dam body 12 bottom, and water pump impeller, main shaft and other main components are made of stainless steel material.Sand pump 1 output end and jet pipeline 8 inside are connected with pipeline 7.

[0029] Referring to Figure 2The maintenance assembly comprises a maintenance rack 6 fixedly connected at the top of the dam body 12, and a hand-operated hoist 5 is installed at the top edge of the maintenance rack 6 and located directly above the sand flushing pump 1. Workers can put down the hook component by rotating the handle of the hand-operated hoist 5, and then cooperate with the hook component and the hooking structure at the top of the sand flushing pump 1. Since the sand flushing pump 1 is fixed on the bottom wall of the dam body 12 by using the automatic coupling base, the sand flushing pump 1 can be conveniently taken out from the bottom of the rubber dam for maintenance when the hand-operated hoist 5 is started to lift the sand flushing pump 1 upward.

[0030] With reference to Figures 1-4 The jet assembly 2 comprises a first jet nozzle 21 and a second jet nozzle 22, both of which are in communication with the inside of the jet pipeline 8. The horizontal installation angle of the first jet nozzle 21 is upward by 15°, and the horizontal installation angle of the second jet nozzle 22 is downward by 45°. Each branch pipe of the jet pipeline 8 is connected with 7 jet nozzles. Four first jet nozzles 21 are installed at an angle of 15° upward horizontally, and the remaining three second jet nozzles 22 are installed at an angle of 45° downward horizontally. A total of 14 jet nozzles are installed in a welding manner between the jet nozzles and the jet pipeline 8 made of stainless steel. Meanwhile, a steel plate is arranged at the bottom of the water intake 9 to avoid the direct scouring of the high-pressure water flow generated by the sand flushing pump 1 and the jet assembly 2 on the bottom plate, thereby prolonging the service life of the water intake 9.

[0031] With reference to Figure 2 A plurality of supports 11 are installed at the bottom of the pipeline 7 and fixed at the bottom wall of the dam body 12. The pipeline 7 is supported by the supports 11 to ensure that the pipeline 7 can be kept stable when the sand flushing pump 1 inputs the high-pressure water flow into the inside of the pipeline 7, thereby forming a stable jet to scatter the silt accumulated in the water intake 9.

In addition, the FM2013 controller supports connection with liquid level sensor, ultrasonic liquid level instrument and other equipment, realizes automatic detection of the running state of the water pump. The controller 4 is electrically connected with the sand flushing pump 1, the ultrasonic sludge interface meter 3 and the water filling pump 10 respectively, the running state of the sand flushing pump 1 and the water filling pump 10 can be automatically detected through the controller 4, the over temperature and water shortage that may occur in the running process of the sand flushing pump 1 and the water filling pump 10 are monitored, so as to ensure the normal operation of the equipment. Secondly, the controller 4 and the ultrasonic sludge interface meter 3 can effectively transmit information, the ultrasonic sludge interface meter 3 will transmit the real-time detected thickness of the accumulated silt to the controller 4, the threshold value of the thickness is set in the controller 4 in advance, when the thickness value detected by the ultrasonic sludge interface meter 3 exceeds the threshold value preset by the controller 4, the controller 4 will control and start the sand flushing pump 1, and the sand flushing pump 1 will disperse the silt accumulated in the water inlet 9, and then the water filling pump 10 will be started to discharge the silt from the inside of the water inlet 9.

[0033] Working principle: when the silt accumulated in the water inlet 9 increases, the ultrasonic sludge interface meter 3 detects the thickness of the silt accumulated in the water inlet 9 in real time through the emitted ultrasonic wave, when the thickness of the silt accumulation reaches the set threshold value, the ultrasonic sludge interface meter 3 will transmit the detected signal to the controller 4, then the controller 4 receives the signal and starts the sand flushing pump 1, the sand flushing pump 1 will continuously deliver high pressure water flow into the jet pipe 8 through the pipeline 7, then the high pressure water flow will be sprayed into the water inlet 9 through the first jet nozzle 21 and the second jet nozzle 22 distributed on the jet pipe 8, the silt in the water inlet 9 can be dispersed by the jet assembly 2 to form a high sand content water body. Then the controller 4 will control the water filling pump 10 to start, and the high sand content water body in the water inlet 9 will be quickly discharged through the water filling pump 10, so as to avoid the silt accumulation in the water inlet 9. Thus, the operation reliability of the water filling pump 10 is improved, the silt entering the rubber dam is reduced, and the service life of the rubber dam is prolonged.
