It sets, one end of the middle part of stull 14 and each diagonal brace 15 passes through bolt and connect to form rice font support frame with connecting plate 13, each oblique
The other end of support 15 passes through bolt respectively and is connected on two side arms 11, is separately connected on each side arm 11 there are two diagonal brace 15,
Convenient transportation is carried and is installed and disassembled after making.
In the present embodiment, connection frame 1 is connected to the medium position of gate pier height by first axle 5, as shown in Fig. 2, A,
B, tri- positions C are respectively that turning hinge formula blocks the working condition that dirty drift comes peak level, ordinary water level and lowest water level, block dirty frame
The height of frame 2 can change with the variation of water level, and the inclined direction and tilt angle of connection frame 1 can also change, with suitable
The variation of the position of dirty frame 2 should be blocked, connection frame 1 is connected to the medium position of gate pier height, then the connection frame 1 of equal length,
The range for being suitable for SEA LEVEL VARIATION is wider.
If connection frame 1 to be arranged in the other positions of gate pier, the length between 1 both ends of connection frame needs to be greater than reservoir
Peak level and the distance between lowest water level, dirty demand is blocked to different water levels to meet.
It blocks dirty frame 2 and trash rack 3 is Q235 carbon steel material, coat anti-corrosion paint layer after carrying out derusting by sandblasting, prevent water
Corrosion.
Specific examples are applied in the present invention, and principle and implementation of the present invention are described, above embodiments
