Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, detailed description is further done to the present invention:
The adjustable for height floating box type upstream of water inlet as shown in Fig. 1-4 controls weir gate, comprise the weir gate 2 being arranged at runner 1 side, the buoyancy tank room 3 being arranged at runner 1 opposite side, described weir gate 2 is fixed on the side of rotating shaft 5, the opposite side of described rotating shaft 5 is fixed with buoyancy tank 6, and described buoyancy tank 6 is arranged in buoyancy tank room 3; The two ends of described rotating shaft 5 are articulated with on the flow path wall 4 of runner 1 both sides respectively, are flood discharge passage 23 between the flow path wall 4 of described buoyancy tank 6 and runner 1 side; The both sides of the edge of weir gate 2 and bottom margin respectively with both side surface and the bottom fitted seal of flood discharge passage 23; Buoyancy tank room 3 has water inlet 9 on the side sidewall of water (flow) direction, and the side sidewall of buoyancy tank room 3 water (flow) direction dorsad has weep hole 10, and buoyancy tank room 3 is also hinged with and regulates buoyancy tank room 3 to intake the adjustment weir plate 11 of height on the side sidewall of water (flow) direction.By the structure retaining of buoyancy tank room 3, when suffered by buoyancy tank 6, buoyancy is greater than the gravity of weir gate 2, weir gate 2 opens flood discharge, and after water level decreasing, buoyancy suffered by buoyancy tank 6 reduces, weir gate 2 is slowly closed, realize opening and closing automatically of weir gate 2, its structure is simple, reasonable in design, effectively reduce energy consumption, device practicality is high.By the water inlet height regulating the structure of weir plate 11 to regulate buoyancy tank room 3, thus have adjusted the Lift of weir gate 2.
As shown in Figure 4, described buoyancy tank room 3 is a cascaded surface towards the sidewall surfaces of water (flow) direction side, comprise first wall 22.1 vertical with runner bottom surface 7, be connected with the top of the first wall 22.1 and second wall 22.2 vertical with the first wall 22.1, and be connected with the rear portion of the second wall 22.2 and three wall 22.3 vertical with the second wall 22.2; Described water inlet 9 is opened on the second wall 22.2.
In technique scheme, the top of described first wall 22.1 is fixed with footing support for slice 12, and described adjustment weir plate 11 is articulated with on footing support for slice 12.
In technique scheme, described footing support for slice 12 is arranged at the both sides of the first wall 22.1, and the two bottom sides of described adjustment weir plate 11 is provided with bearing pin 13, and described bearing pin 13 is articulated with in footing support for slice 12.
In technique scheme, the top of described adjustment weir plate 11 is connected with wire rope 14, and described wire rope 14 is connected with handwheel 15, and described handwheel 15 is positioned at above the second wall 7.2.
By the rotation of handwheel 15, realize the folding and unfolding of wire rope 14, the bearing pin 13 of weir plate 11 bottom it is regulated to rotate, make the apical side height of adjustment weir plate 11 adjustable, water just enters in buoyancy tank room 3 by water inlet 9 after must pass over and regulating weir plate 11, therefore the water inlet height adjustable of buoyancy tank room 3, regulate the simple to operate of weir plate 11, structural stability is high.
In technique scheme, be also provided with fixed weir 16 in described upstream canal 1, described fixed weir 16 is positioned at the front of buoyancy tank room 3, and fixed weir 16 is positioned at the top of water inlet 9.Fixed weir 16 is positioned at above water inlet 9, effectively can tackle the floating thing in water, avoids floating thing to block weep hole 10 or water inlet 9, further ensures stability when weir gate 2 opens and closes.
In technique scheme, the flow path wall 4 of described both sides is symmetrically fixed with bearing (setting) plate 17, described bearing (setting) plate 17 is fixed with bearing, the two ends of described rotating shaft 5 are arranged in bearing.The articulated structure of rotating shaft 5 is simple, and be easy to install, practicality is good.
As shown in Figure 2 and Figure 4, be fixedly connected with polylith buoyancy tank fixed head 18 between the top of described buoyancy tank 6 and rotating shaft 5, described buoyancy tank fixed head 18 is evenly arranged in the top of buoyancy tank 6 along the width of buoyancy tank 6.Ensure buoyancy tank 6 and the bonding strength of rotating shaft 5 by the structure of polylith buoyancy tank fixed head 18, ensure the uniform force of buoyancy tank 6.
As shown in Fig. 1-3, between described weir gate 2 and rotating shaft 5, be fixedly connected with weir gate fixed bar 19.Described weir gate 2 has been evenly arranged many group weir gate fixed bar assemblies along its width, often organizes weir gate fixed bar assembly and comprises two acutangulate weir gate fixed bars 19.Ensure that the bonding strength between weir gate 2 and rotating shaft 5 by the structure organizing weir gate fixed bar 19 more, and the hoisting capacity of weir gate 2 is larger, ensure that weir gate 2 is for the rising of water level and being quick on the draw of reduction, can reach effect and the object of timely flood discharge, further increase the practicality of device.
In the present invention, box typed structure made by weir gate 2 and buoyancy tank 6, can be carried out the weight of adjustable checkgate 2 by modes such as water fillings.Adjustable weir plate 11 before the water inlet 9 of buoyancy tank room 3 is connected with handwheel 15 by wire rope 14, namely starter motor 20 or rotation handwheel 15 drive the bearing pin 13 of adjustable weir plate 11 bottom it to rotate by wire rope 14, thus regulate the height at adjustable weir plate 11 top, also just have adjusted buoyancy tank room 3 and to intake the height of water level.The height of fixed weir 16, higher than the water inlet height of buoyancy tank room 3, can tackle the floating thing in water.
The opening and closing of the weir gate 2 designed by the present invention are controlled by buoyancy tank 6, along with before weir, water level rises gradually, when water level rises to setting height, water enters into buoyancy tank room 3 by adjustable weir plate 11 overflow at water inlet 9 place, buoyancy tank 6 is subject to buoyancy of water, when when the buoyancy torque suffered by buoyancy tank 6 and water, the pressure moment to weir gate 2 is greater than the gravity torque of weir gate 2, weir gate 2 can be opened rapidly, reaches the object of flood discharge.Because water is discharged below weir gate 2, therefore weir gate 2 also can tackle the floating thing in water.Water in buoyancy tank room 3 flows out from weep hole 10, and because the aperture of weep hole 10 is very little, so when before weir during water level decreasing, weir gate 2 can reset by slowly closing.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
