Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 3, weir gate in the utility model comprises water channel 13, water channel side wall 6, weir gate plate 3, buoyancy tank 2, axis of rotation 1 and buoyancy tank chamber 4, buoyancy tank chamber 4 is arranged in water channel side wall 6, form a cavity being connected with water channel 13 by an intake tunnel 14, buoyancy tank chamber 4 is the rectangular enclosure of a side opening.Buoyancy tank chamber 4 has an axis of rotation through hole on the water channel side wall 6 of water channel 13 1 sides, and axis of rotation 1 is through axis of rotation through hole.As shown in Figure 2, axis of rotation 1 two ends are provided with fixed head 10, and fixed head 10 is provided with four installing holes, and stone bolt 11 is fixed on the water channel side wall 6 at two ends through installing hole, axis of rotation 1 two ends embed in fixed head 10, can rotate in a circumferential direction around the central axis of axis of rotation 1.As shown in Fig. 1,4,5, buoyancy tank 2 is fixed on one end of axis of rotation 1 by several groups of buoyancy tank support arms 12, and weir gate plate 3 is fixed on axis of rotation 1 by several groups of weir gate plate support arms 7, and buoyancy tank 2 and weir gate plate 3 lay respectively at the both sides of axis of rotation 1.Weir gate plate 3 comprises weir gate backboard portion 22 and weir gate front edge of board 23, and weir gate plate is the step that extend to both sides at back.Wherein weir gate plate support arm 7 is made up of the top braces arm 8 and the back-supported arm 9 that are mutually angle, and top braces arm 8 is connected with weir gate plate 3 tops, and back-supported arm 9 is fixedly connected with weir gate plate 3 backs.Buoyancy tank 2 is positioned at buoyancy tank chamber 4 and is positioned at the downstream of axis of rotation 1, and weir gate plate 3 is positioned at the water channel in 4 outsides, buoyancy tank chamber.Buoyancy tank 2 is closed enclosure body structures, it comprises junction plate 17, top board 16, the base plate 15 parallel with water channel bottom, away from axis of rotation and the front side board 18 being obliquely installed, near axis of rotation and the back side panel 19 being obliquely installed and left and right end plate 20, front side board 18 lower ends are connected with base plate 15, upper end is connected with top board 16, back side panel 19 lower ends are connected with base plate 15, and upper end is connected with junction plate 17.The length of back side panel 19 is greater than the length of front side board 18, the distance of the center of rotation of buoyancy tank 2 distance of centre of gravity axis of rotation 1 be greater than buoyancy tank 2 away from axis of rotation solstics apart from 1/2 of the center of rotation distance of axis of rotation 1.The buoyancy tank 2 operating by lever principle like this can increase the arm of force and obtain more high-torque, and buoyancy tank is more easily floated.Water channel 13 bottoms below weir gate plate 3 are provided with a seal boss raising up 21, the consistency of thickness of the width of sealing boss 21 and weir gate plate 3, weir gate plate 3 is provided with the weir gate sealing ring 5 for sealing with the seal boss 21 of water channel bottom and water channel side wall 6 touching positions of both sides.
Operating principle of the present utility model is as follows: the calculating of buoyancy when lowest water level by the main drain water channel draining downstream of rainwater storage pond, makes buoyancy tank 2 suffered buoyancy in the time of lowest water level equate with gravity.When in water channel during lower than lowest water level, the buoyancy that the water level of buoyancy tank chamber 4 produces is not enough to maintain the gravity of buoyancy tank 2, and buoyancy tank 2 sinks.Because weir gate plate 3 is positioned at the opposite side of axis of rotation 1, under the drive of axis of rotation 1, weir gate plate 3 moves upward, and weir gate is opened.The rainwater storage pond that is now positioned at weir gate front end is by the water channel draining of the weir gate opened main drain downstream.In the time that the height of water level in water channel reaches lowest water level, the suffered buoyancy of buoyancy tank can support its gravity, buoyancy tank 2 floats, and the weir gate body 3 that is positioned at axis of rotation 1 opposite side moves downward under the drive of axis of rotation 1, weir gate is closed, due to the sealing function of weir gate sealing ring 5, rainwater storage pond stops to water channel internal drainage again.Due to orientation draining under being of weir gate employing, floating thing is all tackled by weir gate body 3, thereby has prevented the pollution of water body.And so forth, realized according to the function of the water level automatic-discharging rainwater in water channel.
The above; be only detailed description of the invention of the present utility model, it should be pointed out that any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.
