Detailed description of the invention
As shown in Figure 1 to Figure 3, the mechanical constant-current device of the utility model design, comprise the frame 1 be fixed on runner, described frame 1 top is rotationally connected a fork 3 by the first rotating shaft 2, one end that described fork 3 is positioned at frame 1 downstream is provided with adjustment weight 4, and the one end being positioned at frame 1 upstream is rotationally connected connecting rod 6 by the second rotating shaft 5; Described connecting rod 6 is provided with the 3rd rotating shaft 7; Be provided with lock seat 8 bottom described frame 1, above described lock seat 8, be provided with gate 9; Described gate 9 one end is rotationally connected with frame 1 by the 4th rotating shaft 10, and the other end is connected with described 3rd rotating shaft 7; Described connecting rod 6 is provided with groove 11 of weighing, described in groove 11 of weighing be positioned at the downstream of described frame 1.
Again as shown in Figure 2, described connecting rod 6 comprises vertical portion 6.1 and horizontal part 6.2; Described vertical portion 6.1 is positioned at the upstream of described frame 1, and one end, described vertical portion 6.1 is connected with the second rotating shaft 5, and the other end is fixedly connected with described horizontal part 6.2; Described horizontal part 6.2 one end extends the downstream of described frame 1, and described horizontal part 6.2 bottom surface is connected with described groove 11 of weighing.Like this, can only move up and down under groove 11 of weighing is due to the spacing effect at current of connecting rod 6 and fork 3.Further, weigh described in groove 11 and be provided with deflector 12; Described deflector 12 one end near described in weigh groove 11 end face, the other end is downward-sloping along flowing to.Further, described deflector 12 is arc deflector, and the recess of described arc deflector is bottom frame 1.Like this, by the effect of deflector 12, further guide current thus the length of the groove 11 that can reduce to weigh, and the efficiency of adjust flux can be improved.
Again as shown in Figure 2, weigh described between the bottom surface of groove 11 and described lock seat 8 end face and be provided with drop a.Further, the bottom surface of groove 11 is weighed described in lower than described lock seat 8 end face.
Again as shown in Figure 2, described gate 9 is Segment gate, and the arc end of Segment gate is connected with described 3rd rotating shaft 7, and the other end is connected with the 4th turn of 10 axles.Further, described gate 9 is connected with described 3rd rotating shaft 7 by junction plate 13; Described junction plate 13 is provided with waist-shaped hole 13.1, and described 3rd rotating shaft 7 is connected with junction plate 13 through described waist-shaped hole 13.1.Like this, waist-shaped hole 13.1 pairs of gates 9 are utilized to carry out spacing and regulating gate 9.
Again as shown in Figure 2, described adjustment weight 4 two ends are provided with spacing regulating part 14, and described spacing regulating part 14 is threaded with described fork 3.Like this, regulated the position of weight 4 by spacing regulating part 14, thus control the size of constant flow rate.
Further, described in weigh groove 1 for casing, and the two side of vertical run is opening.
Operating principle of the present utility model:
In dry season, upper pond level is not high, and the outfall of gate 9 is standard-sized sheets, and the flow velocity of water is not restricted, and the sediment in water washes away with water.Therefore, sediment is not had in side, upstream.Now, gate 9, the groove 11 and regulate weight 4 to be in original position of weighing---that is to say, groove 11 of weighing in the visual angle at Fig. 2 place is moved upwards up to extreme position, regulates weight 4 clockwise oscillation.
When raining, along with the water level of upstream raises, the increased flow capacity of the water flowed through, mean that the jet power that the weight of water on groove 11 of weighing and water spray to groove 11 of weighing downwards strengthens, the groove 11 that makes to weigh moves in parallel downwards, and drivening rod 6 moves down, so, 9, the gate be connected with the 3rd rotating shaft 7 to lower swing, closes the outfall of paddle 9 around the 4th rotating shaft 10; Meanwhile, connecting rod 6 drives fork 3 to swing by the second rotating shaft 5, and then can start adjustment process by regulating weight 4.The water level of upstream is higher, and the gravity and the jet power that groove 11 of weighing are subject to water are larger, and the downward amount of parallel movement of groove of weighing is larger, then the outfall of gate 9 is just closed less.On fork 3, gravity and the pass traffic flowing through water on groove 11 of weighing of the adjustment weight 4 of one end always balances each other to the downward pulling force of the other end on fork 3.Therefore, how the water level regardless of upstream changes, always the flow of the water flowed through keeps constant.By regulating the adjustment of spacing regulating part 14 to regulate the axial location of weight 4 on fork 3, the size of the constant flow rate flowing through the utility model water just can be changed.
If upstream is due to clogging deposits, the flow flowing through water of the present utility model is reduced, the jet power that the weight of water on groove 11 of weighing and water spray to groove of weighing downwards will reduce, the groove 11 that makes to weigh moves up, simultaneously, gate 9 upwards swings around the 4th rotating shaft 10, opens the outfall of large gate 9, and the sediment of gathering is flushed away under the impact force of water.
The track of the utility model water as shown in phantom in Figure 2.
