The culvert system in a kind of used for aquiculture pond
Technical field
What the present invention relates to is the culvert system in a kind of used for aquiculture pond, belongs to aquaculture equipment technical field.
Background technology
Aquaculture is an important component part of agricultural production, along with participating in pond, the more people of economic development of China cultivates up, but the aquaculture most important is exactly the problem of water quality, traditional aquaculture relies on loaded down with trivial details operation, carry out the replacing of pond waters, need to use a large amount of manpowers, also utilize some equipment to change, reach the water circulation use of cultivating pool, but these manpower and materials are all major parts that increases cost.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, provide a kind of simple in structure, easy to use, can effectively reduce production costs, can be fast and effectively regulate the water yield and the water quality of cultivating pool, guarantee the culvert system in the used for aquiculture pond that aquaculture process is normally carried out.
The object of the invention is to be achieved through the following technical solutions: it comprises a pond for aquaculture, on the limit in pond, be provided with a middle retaining well, in this centre retaining well, be respectively arranged with water supply water inlet and the water supply and drainage mouth outreaching; In the middle of described the bottom of retaining well be provided with one that be communicated with pond, with the delivery port of drainage switch device, and in the upper portion side wall of middle retaining well, be provided with the water inlet in a direct or indirect communication pond.
The bottom in described pond is provided with a discharge outlet with filter, this discharge outlet is communicated in and is positioned at the delivery port arranging in middle retaining bottom by drainage channel, on this delivery port, be connected with a bit of outlet pipe, on this outlet pipe, disposing one can direct sealed socket long tube cover thereon, and forms described drainage switch device.
In the middle of described, between retaining well and pond, be provided with a water inlet Buffer Pool, the water inlet on middle retaining well sidewall is communicated with described water inlet Buffer Pool, and water inlet Buffer Pool is communicated in Bian Bi top, pond by a filter.
Described filter is comprised of the secondary filter arranging respectively in intake Buffer Pool water outlet place and wall water inlet place of limit, pond, and described in this, secondary filter and the filter that arranges at pond bottom discharge outlet place consist of conveniently replaced at least one deck screen pack respectively.
The present invention has simple in structure, easy to use, can effectively reduce production costs, can be fast and effectively regulate the water yield and the water quality of cultivating pool, guarantee that aquaculture process the feature such as normally carries out.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is done to detailed introduction: shown in Fig. 1, the present invention includes a pond 1 for aquaculture, be provided with one on the limit in pond 1 in the middle of, retaining well 2, is respectively arranged with water supply water inlet 3 and the water supply and drainage mouth 4 outreaching in this centre retaining well 2; In the middle of described the bottom of retaining well 2 be provided with one that be communicated with pond 1, with the delivery port 6 of drainage switch device 5, and in the upper portion side wall of middle retaining well 2, be provided with the water inlet 7 in a direct or indirect communication pond 1.
Shown in figure, the bottom in described pond 1 is provided with a discharge outlet 9 with filter 8, this discharge outlet 9 is communicated in and is positioned at the delivery port 6 arranging on middle retaining well 2 bottoms by drainage channel 10, on this delivery port 6, be connected with a bit of outlet pipe 11, on this outlet pipe 11, disposing one can overlap 12 by direct sealed socket long tube thereon, and forms described drainage switch device 5; The on-off principle of described drainage switch device is mainly to utilize the effect of water level, when long sleeve pipe 12 is socketed on outlet pipe 11, because two pipes connect place's good seal performance, so, the top of long sleeve pipe 12 exceeds normal cultivation water level in pond, now, the water in pond can not discharged from the delivery port 6 of bottom; When need to discharge in pond water time, as long as long sleeve pipe 12 is taken away, now outlet pipe tip position is lower than the water level in pond, at this time the water in pond just can flow into centre retaining wells 2 through drainage channels from delivery port 6; And water level in middle retaining well 2 also can be controlled by the water supply water inlet 3 and the water supply and drainage mouth 4 that outreach, in specific embodiment, at described water supply water inlet 3 and water supply and drainage mouth 4 places, all can configure the switch of can manual adjustment controlling so that by water from outside access or give off.
Other embodiments of the invention can be communicated with two or more cultivating pools by a retaining well, be convenient to water yield regulation and control each other.
The present invention is also provided with a water inlet Buffer Pool 13 between described middle retaining well 2 and pond 1, and the water inlet 7 on middle retaining well 2 sidewalls is communicated with described water inlet Buffer Pool 13, and water inlet Buffer Pool 13 is communicated in the top of pond 1 limit wall by a filter 14.
Described filter 14 is comprised of the filter arranging respectively in water inlet Buffer Pool 13 water outlets place 15 and limit, pond wall water inlet place 16 and secondary filter, and described in this, filter and secondary filter and 1 bottom discharge mouth place arranges in pond filter consist of conveniently replaced at least one deck screen pack respectively, by water inlet Buffer Pool 13 and filter 14 are set, be conducive to enter the requirement that water quality in pond meets aquaculture.
