Specific embodiment

In order to make the above-mentioned features and advantages of the utility model more obvious and understandable, special embodiment below, and cooperate attached drawing, It is described in detail below.

As shown in Fig. 1 ~ 6, a kind of fish pond blowdown apparatus is described to breed fish including open crawl 1 and float pond 2 upward It is connected between pond and the bottom in float pond through communicating pipe 3, the connection bottom of the tube is equipped with sewage draining exit 4, cuts with scissors on the sewage draining exit It is connected to a switch gate 5；The inside in the float pond is fixed with an open cylinder 6 upward, the bottom coaxial communication of the cylinder There is the first tubule 7, drawstring 8 of the non-articulated end of the switch gate through penetrating along the first tubule bottom opening is floating with cylinder interior Son 9 is connected.

In the utility model embodiment, the peripheral part of the cylinder is connected through the inner peripheral portion of support rod 10 and float pond is One, the sewage draining exit lower section are connected with sewage pipe 11.

In the utility model embodiment, the bottom opening of first tubule is connected to float pond, first tubule Internal diameter be less than the internal diameter of cylinder, the internal diameter of first tubule is less than the internal diameter of sewage draining exit, and the outer diameter of the float is less than circle The internal diameter of cylinder, greater than the internal diameter of the first tubule, the volume of the crawl is greater than the volume in float pond, in blowdown in float pond Water can take the lead in draining；The internal diameter of first tubule is thinner, clearly shows that its structure is exaggerated processing in figure.

In the utility model embodiment, the sewage draining exit is located at the underface in float pond, and the switch gate is supported with separate The pool wall in fishpond is hinged.

In the utility model embodiment, the bottom of pond of the crawl is equipped with a dirt groove 12, the dirt groove Notch is equipped with the filter screen 13 for preventing fish from entering, and one end of the communicating pipe is connected to the slot bottom of dirt groove.

In the utility model embodiment, second be co-axially inserted inside the first tubule is fixed on the bottom surface of the float Tubule 14, the outer diameter of second tubule are equal to the internal diameter of the first tubule, and the bottom opening of second tubule and float pond connect Logical, the circumference of second tubule offers limbers 15 and lower limbers 16, and the lower circumference of first tubule offers For being connected to the drainage hole 17 of lower limbers；The internal diameter of second tubule is thinner, in figure in order to clearly show that its structure into Enhanced processing is gone.

In the utility model embodiment, electromagnetic valve is installed, electromagnetic valve is only under float on the drainage hole Dropping to certain altitude i.e. switch gate will just work when quick closedown and connects drainage hole.

In the utility model embodiment, the top edge of the upper limbers is flushed with the bottom surface of float.

A kind of method for discharging pollution of fish pond blowdown apparatus, when sequentially including the following steps: (1) original state, switch gate is closed On sewage draining exit, crawl is flushed with the liquid level inside float pond because keeping communicating pipe；(2) water inside float pond is from tubule under Cylinder interior is up gradually submerged, float floats when cylinder interior liquid level rises to a certain position, and float is opened through drawstring drive Shutdown is up turned on along its hinged end, and sewage draining exit starts blowdown；(3) water inside float pond is quickly discharged along sewage draining exit, cylinder Slowly because of the draining of bottom tubule, switch gate is along hinged end slowly closing at this time for internal water；(4) when switch gate rotary closing to certain When one angle, since the water in crawl is still constantly towards sewage draining exit blowdown, part of contaminated water flows to separate breed fish at the top of switch gate The pool wall in pond, then impulse interference wave switch header surface back of rebounding, when the resultant force of the impact force and switch gate gravity is floating greater than float When power, switch gate is rapidly turned off, while float blocks tubule by rapid drop-down；(5) it since switch gate is rapidly turned off, breeds fish Water in pond is rushed from lower to upper toward float pond, and under momentum effect, the liquid level in float pond is temporarily higher than the liquid level of crawl (height Poor H), as float pond liquid level is fallen after rise, the water flow of falling will be adsorbed on the dirt breeded fish on bottom of pond portion filter screen, fish break up, It avoids blocking, as time goes by, the liquid level in float pond is flushed with the liquid level of crawl again；(6) water inside float pond is again Cylinder interior is gradually submerged from lower to upper from tubule, and when cylinder interior liquid level rises to a certain position, float floats, and repeats Above step carries out blowdown process again.

In the utility model embodiment, in step (4), when switch gate rotary closing is to a certain angle, gradually under The lower limbers of second tubule of drop and drainage hole are connected, the water in cylinder other than along the discharge of the second tubule bottom opening, It is also discharged along lower limbers, drainage hole, drainage speed increases, and can be pulled down rapidly in float fast on the node for blocking tubule Speed drains remaining water in cylinder, avoids remaining water in cylinder that from can not draining.

In the utility model embodiment, in step (6), when the water in crawl rushes past float pond from lower to upper, Water starts to submerge from lower to upper from the second tubule, and float is jacked up a bit of gap by the water flow of rising connects upper water flowing bore portion Cylinder submerges cylinder convenient for water flow, which is equal to the surplus of drawstring, and drawstring is in relaxed state when switch gate is closed, Drawstring is just tightened when float is jacked up a bit of gap by the water flow of rising, but since float buoyancy at this time is also too small, is not enough to Switch gate is pulled open, only when cylinder interior liquid level rises to a certain position, float can just float.

The utility model is not limited to above-mentioned preferred forms, anyone can obtain under the enlightenment of the utility model Other various forms of fish pond blowdown apparatus out.All equivalent changes and modifications done according to present utility model application the scope of the patents, The covering scope of the utility model should all be belonged to.
