Description
Technical field
The utility model relates to hydraulic dam technical field, especially a kind of dam body is equipped with the hydraulic dam of buffer structure.
Background technique
Hydraulic dam is widely used in agricultural irrigation, fishery, ship lock, seawater as a more easy movable dam technology
The fields such as gear tide, city river landscape engineering and small hydropower station.Hydraulic dam is mainly made of movable dam body and hydraulic stem, hydraulic stem
Support force is provided for dam body.Water flow impacts dam body for a long time, is easy to cause the damage of hydraulic stem.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of hydraulic dam of the dam body equipped with buffer structure.
A kind of buffering hydraulic dam, including dam body, the dam body inside are vertically equipped with identical first magnetic sheet of polarity and second
Magnetic sheet, first magnetic sheet are fixed on back side side, and the dam is fixed on by sliding rail in the second magnetic sheet top and bottom
Internal portion；The dam body is connected with buffer board by adjustable spring, and the buffer board connects second magnetic sheet by push rod.
Further, the dam body is equipped with adjustable spring through hole to the water surface, is internally provided with adjustable spring follow block；It is described
It is equipped with water fender at the top and bottom of buffer board, is equipped with water fender slot at the top and bottom of the dam body.
Further, it is connected with anti-drop rod at the top and bottom of the buffer board, the anti-drop rod protrudes into the dam body and company
It is connected to limit plate；The anti-drop rod connects the length after the limit plate and is less than the push rod.
Further, the buffer board is the thin streamlined structure in thick middle both sides.
The utility model has the beneficial effects that the spring buffer knot when water flow generates impact force to dam body, based on spring
Structure and the magnetic sheet buffer structure based on magnetic sheet can assist dam body to play the role of resisting water impact simultaneously.
Detailed description of the invention
Fig. 1 is the schematic diagram of internal structure of embodiment 1；
Fig. 2 is the schematic diagram of internal structure of embodiment 2；
Fig. 3 is the structural schematic diagram of adjustable spring follow block in embodiment 2.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, technical solutions of the utility model are clearly and completely described, are shown
So, the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Based in detail below
Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all
Belong to the range of the utility model protection.
Embodiment 1
A kind of buffering hydraulic dam is vertically equipped with polarity identical first inside the dam body as shown in Figure 1, including dam body
Magnetic sheet 1 and the second magnetic sheet 2, first magnetic sheet 1 are fixed on back side side, pass through cunning at the top and bottom of second magnetic sheet 2
Rail 3 is fixed on inside the dam body；The dam body is connected with buffer board 5 by adjustable spring 4, and the buffer board 5 passes through push rod 6
Connect second magnetic sheet 2.In the present embodiment, adjustable spring is equipped with 4 rows, and every row is equipped with several at equal intervals.
When water flow generates impact force to dam body, the spring buffer structure based on spring and the magnetic sheet based on magnetic sheet are slow
Rushing structure can assist dam body to play the role of resisting water impact simultaneously.When buffer board is by water impact, to adjustable spring
It is squeezed, adjustable spring generates bounce, realizes first-level buffer；Buffer board is mobile to dam body side under water impact, the
Two magnetic sheets reduce at a distance from the first magnetic sheet under the promotion of push rod, so that receiving the repulsive force of the first magnetic sheet, realize that second level is slow
Punching.Although hydraulic stem still will receive certain power, and adjustable spring is shunk and expansion due to the relationship of active force and reaction force,
Most water flow impact pressure can be cleared up, water flow is reduced to the impact force of hydraulic stem, improves its service life.
First, second magnetic sheet can realize in such a way that thistle board is embedded in several magnetic sheets, and the particular number of magnetic sheet can be with
Repulsion dynamics setting as needed；Certainly, the magnetic sheet on the first, second magnetic sheet should be oppositely arranged.
Embodiment 2
On the basis of embodiment 1, the dam body is equipped with adjustable spring through hole 7 to the water surface, is internally provided with flexible bullet
Spring follow block 8, as shown in Figure 2 and Figure 3；It is equipped with water fender 9 at the top and bottom of the buffer board 5, is equipped at the top and bottom of the dam body
Water fender slot 10.The supplementing structure of the present embodiment, so that buffer board can be closed under the impact of water flow with dam body, stretch bullet
Spring is closed in inside, hinders from water erosion and mud.It can be used between water fender and water fender slot and be slidingly sealed knot
Structure improves its leakproofness.
Anti-drop rod 11 is connected at the top and bottom of the buffer board 5, the anti-drop rod 11 protrudes into the dam body and is connected with
Limit plate 12；The anti-drop rod 11 connects the length after the limit plate 12 and is less than the push rod 6.Buffer board disconnecting prevention structure
Setting, improves its stability connecting with dam body, while playing the role of guide rod.
The adjustable spring follow block is arranged in dam body inner transverse, avoids push rod and anti-drop rod.
The buffer board is preferably the thin streamlined structure in thick middle both sides, can dispersing water flow impact force, by water flow
Impact force guides up and down, reduces the impact force to dam body.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
