The Pule flow meter 8 and the third acoustic Doppler flow meter 9, the first acoustic Doppler flow meter 7, the second acoustic Doppler flow meter 8 and the third acoustic Doppler flow meter 9 are connected with three The ultrasonic Doppler flowmeter host has a line connection, and the drainage device 10 is provided on the right of the sewer pipe 2. The first indicator, the second indicator, the third indicator, the fourth indicator and the LCD display are all controlled by the line Module connection.
[0030] The drainage device 10 includes a first water pump 101, a water outlet pipe 102, a water inlet pipe 103, a second water pump 104, a third water pump 105, a fourth water pump 106, and a frame 107. A frame 107 is embedded on the right side of the downpipe 2, A first water pump 101, a second water pump 104, a third water pump 105, and a fourth water pump 106, a first water pump 101, a second water pump 104, a third water pump 105, and a fourth water pump are installed on the top of the frame 107 sequentially from back to front. 106 is connected to the right side of the water outlet pipe 102, the water outlet pipe 102 passes through the right side of the frame 107, the first water pump 101, the second water pump 104, the third water pump 105 and the fourth water pump 106 are connected to the bottom of the water inlet pipe 103, the water inlet pipe 103 passes through the bottom of the frame body 107, and the first water pump 101, the second water pump 104, the third water pump 105 and the fourth water pump 106 are all connected with the control module in a line.
[0031] It also includes a first guide sleeve 11, a first guide rod 111, a stop 112, a first spring 113, an articulated seat 114, a swing rod 115, a second guide sleeve 116, a second guide rod 117, a floating tank 118, and a filter screen. 119 and bellows 1110. Four first guide sleeves 11 are embedded and installed evenly spaced from front to back in the middle of the bottom of the frame body 107. The four first guide sleeves 11 are each provided with L-shaped first guide rods 111 , The upper part of the four first guide rods 111 are all connected to the stop block 112, the first guide rod 111 is connected to the stop block 112 by welding connection, and the first spring 113 is wound on the four first guide rods 111. One end of the spring 113 is connected to the bottom of the stop 112, and the other end of the first spring 113 is connected to the top of the first guide sleeve 11. The right side of the inner bottom of the frame 107 is connected with four hinge seats 114 evenly spaced from front to back. The frame 107 passes It is connected to the hinge base 114 by welding. The upper parts of the four hinge bases 114 are all rotatably connected with a swing rod 115. The four swing rods 115 respectively contact the tops of the four first guide rods 111. The bottom right side of the frame 107 extends from the front Four second guide sleeves 116 are embedded and installed evenly spaced in the rear. The four second guide sleeves 116 are equipped with second guide rods 117. The bottom ends of the four second guide rods 117 are all connected with a floating box 118. The two guide rods 117 are connected to the pontoon 118 by welding, the four swing rods 115 are in contact with the tops of the four second guide rods 117 respectively, and the bottoms of the four water inlet pipes 103 are all connected with bellows 1110 and four bellows 1110 A filter screen 119 is fixedly connected to the bottom end, and the four filter screens 119 are respectively connected to the left ends of the four first guide rods 111.
