Detailed Description
As shown in fig. 1 and fig. 2, a gate sensor cavity is with structure of desilting of washing sand, including gate frame 1, gate lower frame 2 and floodgate fan 3, be provided with sensor chamber 4 on the gate frame 1, be provided with a plurality of inlet openings 5 on the upstream surface of sensor chamber 4, sensor chamber 4 is provided with apopore 6 on being close to one side of floodgate fan 3, apopore 6 is corresponding with inlet opening 5's position, inlet opening 5 and apopore 6 all are located the below of floodgate fan 3, inlet opening 5 all are located the top of gate lower frame 2 with apopore 6, the total height about 6 osculums is greater than inlet opening 5's upper and lower total height, the total length of 6 horizontal directions of apopore is less than the total length of 5 horizontal directions of inlet opening.
This embodiment is through rationally arranging inlet opening and delivery port on the sensor chamber, has solved silt and has piled up easily at the sensor chamber, leads to long-term water level to detect inaccurately, and the problem that the silt sand of sensor chamber bottom is difficult to the clearance has guaranteed the normal operating and the use of gate simultaneously, reduces the maintenance cost throughout the year of gate.
Specifically, the upstream surface of the sensor cavity 4 is provided with four water inlets 5 in a rectangular array, and the other side of the sensor cavity 4 close to the brake fan 3 is provided with a longitudinal water outlet 6 corresponding to the water inlets 5.
This embodiment utilizes silt dead weight and rivers to hold sand ability improvement sand washing effect, erodees automatically, can also prevent the silt siltation, can not have the sediment, has solved current problem. The bottom of floodgate fan 3 is higher than the top of apopore 6 or flushes with the top of apopore 6, and inlet opening 5 is close to the top of floodgate lower frame 2 with 6 positions of apopore, and silt is washed away from 3 lower parts of floodgate fan, and under the effect of rivers impulsive force and silt dead weight, effectively washed sand moreover, prevents that silt from silting up.
Specifically, the inlet opening 5 is parallel to the upstream face. The water inlet 5 and the water-facing surface form an included angle which is an acute angle or an obtuse angle.
