Abstract

The utility model discloses a structure for automatically adjusting the water outlet flow of a pool. The structure comprises the pool, wherein a water outlet is formed in the inner side wall of the pool; a supporting plate is arranged on the top of the water outlet; a floating barrel is arranged in the pool and is fixedly connected with a floating barrel connection rod; the tail end of the floating barrel connection rod is hinged to the supporting plate through a rotating shaft; a lever cam is arranged on the rotating shaft; a valve clack matched with the water outlet in a sealing manner is arranged on the water outlet and is fixedly connected with a rotating arm; the tail end of the rotating arm is hinged to the inner side wall of the pool above the supporting plate; the top of the lever cam is in contact with a roller at the bottom of the rotating arm. When the valve clack of the structure is closed, the closing force is realized by water power; a floating device only needs to adjust openness limitation to the valve clack; therefore the structure has a low requirement on the flotage, and the limitation caused by the flotage is low; the lever cam is in contact with the roller of the rotating arm; the actuation operation for controlling the openness of the valve clack is roller rolling, so that the moving force of a lever mechanism is reduced, and the weight of the floating barrel is indirectly reduced; flow adjustment under different working conditions is facilitated.

Background technology

In the facility such as pond or catch basin of drainage system, conventionally need to be according to the size of pool inner water position situation adjusting water outlet flow, wherein, drive the adjustment structure that realizes water flow by buoyancy, do not need the advantage of extra power equipment to there is wide application prospect because it has, still, rely at present the water quantity regulating structure of buoyancy, heavier because of mobile conditioning equipment, need larger buoyancy, exist buoyancy is required to high shortcoming.

Summary of the invention

The purpose of this utility model will provide a kind of pond water flow self-regulation structure exactly, and this structure is subject to buoyancy restriction little, to more flexibility and reliability of Flow-rate adjustment.

For achieving the above object, the technical solution adopted in the utility model is: a kind of pond water flow self-regulation structure, comprise pond, described pond inside wall is provided with delivery port, described delivery port top is provided with support plate, in described pond, be provided with floating drum, on described floating drum, be fixed with floating drum connecting rod, the end of described floating drum connecting rod is hinged on described support plate by rotating shaft, described rotating shaft is provided with lever and cam, described delivery port is provided with the flap being sealed and matched with it, on described flap, be fixed with pivoted arm, the end of described pivoted arm is hinged on the pond inside wall of described support plate top, the top cam of described lever and cam contacts with the bottom roller of described pivoted arm.

The utility model is by the motion of floating drum, drive the lever and cam on it to rotate, and then pivoted arm is rotated, drive flap opens and closes, finally realize the adjusting of water flow in pond, wherein, in the time that water level in water pool is very low, floating drum falls, flap is in fully open position, when water level in water pool raises gradually, flap aperture is more and more less, and in the time that water level in water pool exceeds designated water level, flap is adjusted downward to fastening position in the effect of floating drum connecting rod, flap is automatically closed under hydraulic action, because of the motion of floating drum directly related with the water level in pond, be that the utility model passes through the automatic adjusting water outlet flow of water level in water pool, when the flap of this structure is closed, it is closed power and realizes by waterpower self, and buoyant device only need be realized the spacing adjusting of flap aperture, and therefore this structure is not high to the size requirements of buoyancy, be subject to the restriction of buoyancy little, can be widely used in the facilities such as large-scale catch basin, lever and cam in this structure and pivoted arm roller contact, performing an action as roller rolls of flap aperture control, has reduced the locomotivity of leverage greatly, has indirectly reduced the weight of floating drum, the buoyancy that is conducive to realize under different operating modes is adjusted stream automatically, to more flexibility and reliability of the adjusting of flow.

Further, described floating drum connecting rod comprises two connecting rods that are fixed on described floating drum cylinder face two ends and are parallel to each other, described rotating shaft is hinged on described support plate by shaft hole matching, and the two ends of described rotating shaft are fixedly connected with the end of described two connecting rods respectively, the bottom of described lever and cam is fixed in described rotating shaft.

Further, described flap is provided with sealing ring on the side of itself and delivery port contact side.

Further, described lever and cam comprises the lever of bottom and the cam at top, and described pivoted arm is consistent with contact trace and the described cam profile of described lever and cam.

Further, described delivery port is made up of an outlet pipe, and described outlet pipe protrudes from the inside wall of described pond.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail, is convenient to more clearly understand the utility model, but they do not form and limit the utility model.

As shown in Figure 1, shown in Fig. 2, a kind of pond water flow self-regulation structure, comprise pond 101, described pond 101 inside walls are provided with delivery port 102, described delivery port 102 is made up of an outlet pipe, described outlet pipe protrudes from 101 inside walls of described pond, described delivery port 102 top cross are provided with support plate 103, in described pond 100, be provided with floating drum 104, on described floating drum 104, be fixed with floating drum connecting rod 105, described floating drum connecting rod 105 comprises two bending connecting rods that are fixed on 104 face two ends of described floating drum and are parallel to each other, the end of two bending connecting rods is fixedly connected with a rotating shaft 109, the two ends of described rotating shaft 109 are hinged on described support plate 103 by shaft hole matching, described rotating shaft 109 is provided with lever and cam 106, the bottom of described lever and cam 106 is fixed on the upper of described rotating shaft 109, described delivery port 102 is provided with the flap 107 of salable cooperation, described flap 107 is provided with sealing ring 110 on the side of itself and delivery port 102 contact sides, on described flap 107, be fixed with pivoted arm 108, pivoted arm 108 is convex arc shaped bending, the end of described pivoted arm 108 is hinged on by jointed shaft 111 on pond 101 inside walls of described support plate 103 tops, the top cam of described lever and cam 106 and the crooked position roller contact of described pivoted arm 108, that is: described lever and cam 106 comprises the lever of bottom and the cam at top, described pivoted arm 108 is consistent with contact trace and the described cam profile of described lever and cam 106.

The course of work of the present utility model is as follows: in the time that water level in water pool is low, as shown in Figure 1, floating drum 104 falls, and flap 107 is in fully open position; When pond, 101 water levels raise gradually, floating drum 104 is along with the water level raising rises, the pin joint of floating drum connecting rod 105 on bearing 103 rotates, and then drive the lever and cam 106 in rotating shaft 109 to rotate, because of top and pivoted arm 108 roller contacts of lever and cam 106, and then lever and cam 106 promotion flap 107 close delivery port gradually indirectly, make flap 107 apertures more and more less; And in the time that pond 101 water levels exceed designated water level, as shown in Figure 3, flap 107 is adjusted downward to fastening position in 105 effects of floating drum connecting rod, flap 107 is automatically closed under hydraulic action.
