Structure, the automatic shutter structure include fixed plate 32, are the shallow slot knot of class sector in 32 end face two sides of fixed plate setting cross section
Structure 42,42 medial surface of shallow slot structure are the gradual change curved surface that curvature incrementally increases from the bottom up, right side shallow slot structure 42 just on
The bottom to form entirety and fixing lug boss 34 is connected and fixed with fixed plate 32 on the right side of side's setting fixing lug boss 34 and the fixing lug boss 34
Plate and 32 end face of fixed plate are located in same horizontal line, and the rotary buckle 36 that rotary shaft 31 is arranged in middle part is arranged in shallow slot structure 42
The upper and rotary shaft 31 is fixed on the outer end of shallow slot structure 42；36 inner end of rotary buckle is block 43, outer end is boss knot
Structure 44, block 43 are located in shallow slot structure 42 and can be blocked by 42 medial surface upper end of shallow slot structure, and boss structure 44, which is located at, to be fixed
Plate outer end realizes that 36 rotation amplitude of rotary buckle is controlled by shallow slot structure 44；The fixing lug boss 34 is located at 27 right side of rotating handle
And in same level, spring 33 is set between fixing lug boss 34 and rotating handle 27, is arranged on the right side of fixing lug boss 34
Hook 35, the cord 29 that two one end are provided with plastic bucket 37 respectively passes sequentially through the circular hole of 44 structure of boss, fixed pulley 30
Afterwards, it is connect respectively with hook 35 and rotating handle 27, plastic bucket 37 is freely put into the fixing pipe 11 in corresponding pond 6.
Water inlet 9 wherein is set in 6 side upper end of pond and is connected to corresponding water channel 7, the pond baseboard 2 in the pond 6 is
Right low left high inclined design is easy to drain and remove mud；At least one jump guiding road 1 and corresponding is set on pond baseboard 2
Cord hole a3 and cord hole b17 is respectively set in corresponding 6 two sides of pond of mud pushing plate 4 in mud pushing plate 4, and rope passes through cord hole and mud pushing plate 4
Connection is for pulling mud pushing plate 4 to horizontally slip along guiding road 1,6 one side-lower setting drainage hole 16 and the drainage hole 16 in pond
It is corresponding with guiding 1 position of road, for draining and removing mud, Dang Ni mechanism 5 is set in the pond 6 above mud pushing plate 4；Shelves mud
Mechanism 5 includes the fixation mud guard 15 being horizontally placed in pond, is evenly distributed on the surface of fixed mud guard 15 and passes through up and down
Logical circular through hole, circular through hole is interior to be equipped with first support bar 40, and the lower end of first support bar 40 is fixedly connected with second vertically
Support rod 41, the rotor plate 39 of rotation connection is cased on the left and right ends side wall of second support bar 41, and rotor plate is that lightweight is compound
Plate, very light weight close through-hole convenient for timely corresponding rotation, and the lower end of second support bar is fixedly connected with for limiting
Make the limit plate 38 of two pieces of rotor plates, limit plate may make rotor plate vertical under static state so that be not able to rotate by
The boss for installing water pump 14 should be arranged in 6 right side central of pond in through-hole closing, and drinking-water pipe 13 connects water pump 14 and draws water
Pond 6, when needing with water, the through-hole in Dang Ni mechanism is closed, and pumping for water pump can effectively prevent the mud quilt of basin bottom
Extraction, ensure that the quality of water；27 sets of the rotating handle upper end ends in rotary shaft 25 hold end to pass through screw on the rotary shaft
26 are connected and fixed in rotating handle 27, and in 25 side of rotary shaft, setting connecting key 28 connects 27 inside of rotating handle, in water inlet 9
Strainer 8 is set with 7 junction of water channel, to do preliminary treatment to waste water.
The control principle of the automatic shutter structure of the water valve is: the boss 44 of rotary buckle 36 is than 43 weight of block, in freedom
Under state, rotary buckle 36 can be rotated around rotary shaft 31 toward 44 direction of boss, but since block 43 can be with shallow slot structure 42
Medial surface upper end is blocked, therefore rotary buckle 36 at most turns to horizontality stopping, i.e., when pond a45 and pond b46 are
When empty, both sides plastic bucket 37 is all vacant state, and the rotary buckle 36 on both sides can all be protected in the case where block 43 blocks
Water level state, the valve 19 for controlling pond b46 at this time are opened, and the invention 19 of control pond a45 is closed, and foundation pit waste water flows into water
Pond b46, when water is filled in pond；Plastic bucket in corresponding pond b46 jacks up the convex of corresponding rotary buckle under buoyancy
Platform is the rotary buckle on right side, is rotated down the block of rotary buckle, and the block on right side cannot block rotating handle 27 at this time,
Under the plastic bucket effect being located in the a45 of pond, rotating handle 27 is moved to the left, then the rotation of the control of rotating handle 27 at this time
Shaft rotation, while two valves in rotary shaft also rotate simultaneously, then pond b is closed, pond a water inlet, due to water in a of pond
Water is housed in bucket, under the effect of gravity, rotating handle rotation is pulled by cord, to open the valve of pond a, is simultaneously closed off
The valve of pond b, at this moment foundation pit waste water will flow into pond a.Wherein left end, which is buckled in, will block always rotation when bucket does not open it
Handle is changed hands, as water level increases, bucket opens buckle, and rotating handle pulls back under the action of the spring, and the valve of pond a closes
It closes, the valve in pond 2 is opened, and is formed uninterrupted draining, is realized the mechanical automation of water valve.
Specific overall workflow is as follows:
Foundation pit water is flowed into pond by water channel, and from water valve control foundation pit water flow to which pond, water valve is a kind of machine automatization
Makeup is set, and by water level in water pool come the switch of control valve, the water of collection can provide construction to engineering by water pump in pond
With water, domestic water can be provided by being further processed.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
