Body balancing weight 12 is relatively conventional, draws materials conveniently, low cost.
In technique scheme, the water inlet cross section of described buoyancy tank room water inlet 7 is more than buoyancy tank room apopore 8
Water outlet cross section.Buoyancy tank room water inlet 7 ensure that the fast and stable that buoyancy tank room intakes, the water outlet of buoyancy tank room
The water outlet cross section in hole 8 is little, it is ensured that the water level in buoyancy tank room 6 slowly declines, so that it is guaranteed that gate 1 can
With slowly closing, improve the stability of gate 1 work.
In technique scheme, as shown in Fig. 56, the bottom of described flood discharge passage 24 is fixed with close
Envelope seat 15, the two ends of described seal receptacle 15 are individually fixed in side sidewall and the runner 23 of buoyancy tank room 6
Side flow path wall 4 on；Described seal receptacle 15 and the bottom fitted seal of gate 1, described gate 1
Both sides of the edge and bottom margin be respectively and fixedly provided with sealing ring 16.Gate is ensured by the structure of sealing ring 16
The structure of the seal receptacle 15 bottom the sealing of 1, and runner 23 has also been effectively ensured bottom gate 1
Seal.
In technique scheme, as shown in Fig. 12, right on the flow path wall 4 of described upstream canal both sides
Claim to be fixed with rotating shaft location-plate 17, described rotating shaft location-plate 17 is fixed with bearing, described rotating shaft 3
Two ends are arranged in bearing.The articulated structure of rotating shaft 3 is simple, it is easy to installing, practicality is good.
In technique scheme, as shown in Fig. 12, solid between top and the rotating shaft 3 of described buoyancy tank 5
Determine connection and have polylith buoyancy tank fixed plate 18.Buoyancy tank 5 and rotating shaft is ensured by the structure of buoyancy tank fixed plate 18
The intensity of the attachment structure between 3, further enhances structural stability.
In technique scheme, described buoyancy tank fixed plate 18 is evenly arranged in along the width of buoyancy tank 5
The top of buoyancy tank 5.The connection of buoyancy tank 5 and rotating shaft 3 is ensured by the structure of polylith buoyancy tank fixed plate 18
Intensity, it is ensured that the uniform force of buoyancy tank 5.
In technique scheme, it is fixedly connected with gate between described gate 1 and rotating shaft 3 and fixes bar 19.
In technique scheme, as shown in Fig. 12 and Fig. 56, described gate 1 is disposed with many
Bar assembly fixed by group gate, and often group gate is fixed bar assembly and included that bar 19 fixed by two gates acutangulated.
In technique scheme, described gate is fixed bar assembly and is evenly arranged along the width of gate 1.
The structure fixing bar 19 by many group gates ensure that the bonding strength between gate 1 and rotating shaft 3, and
The hoisting capacity of gate 1 is bigger, it is ensured that gate 1 is for the rising of water level and being quick on the draw of reduction, energy
Reach effect and the purpose of timely flood discharge, further increase the practicality of device.
In the present invention, as it is shown on figure 3, when the liquid level in the aquifer reserve pond 2 in downstream is the lowest, floating
Water in seed cell 9 flows out, and float 11 declines, under the action of gravity of float 11, in buoyancy tank room 6
Balancing weight 12 move upward, buoyancy tank room water inlet 7 is opened, buoyancy tank room 6 start water inlet, buoyancy tank room
6 enter full water after buoyancy tank 5 float, drive gate 1 rotarily open, the aquifer reserve pond 2 in downstream start into
Water.
When the water level in the aquifer reserve pond 2 in downstream rises to storage pond the highest permission water level, ground is lowered
Water in reservoir 2 will enter float chamber 9, and float 11 floats, balancing weight 12 under gravity to
Lower motion, closes buoyancy tank room water inlet 7.The water of buoyancy tank room 6 is after buoyancy tank room apopore 8 flows out, floating
Case 5 rotates down, and drives gate 1 rotary closing, and the water in aquifer reserve pond 2 is arranged to natural water
Put, retentively descend the stable level of storage pond 2.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention not office
Being limited to this, any those of ordinary skill in the art, can be light in the technical scope that disclosed herein
The change being readily conceivable that or replacement, all should contain within protection scope of the present invention.Therefore, the present invention
Protection domain should be as the criterion with the protection domain that claims are limited.
