Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a crab pond structure. Background Art

[0002] In addition to meeting the basic breeding functions, the daily management of crab breeding ponds, such as feeding and fishing, is also critical. The existing crab breeding is a process of breeding large-eyed larvae into 50 to 90 crabs per kilogram. During the whole process, the main feed is sinking granular feed. Most farmers do not pay attention to the size and width of the crab pond. Generally, mobile feeding tables are used to sample and observe the feeding situation of river crabs. Most of the bait is thrown on the mud at the bottom of the pond, especially in the later stage when the feed particles are larger, they will sink into the mud, resulting in a large amount of waste; some farmers do not protect the slope thoroughly, and the crab seedlings dig holes on the slope, which leads to the collapse of the crab pond or the inability of some crab seedlings to escape. Utility Model Content

[0003] In view of the problems in the related technology, the utility model proposes a crab pond structure to overcome the above-mentioned technical problems existing in the existing related technology.

[0004] To this end, the specific technical solutions adopted by the utility model are as follows:

[0005] A crab pond structure comprises a breeding pond body, wherein a pond bank is arranged inside the breeding pond body, a pond bottom is arranged below the pond bank, a water inlet is arranged on one side of the breeding pond body, and a water outlet is arranged on the other side.

[0006] Furthermore, the pond bank includes a pond bank slope, a secondary slope platform and a pond slope protection. A secondary slope platform is provided below the pond bank slope, and the pond slope protection is provided on the pond bank slope and the secondary slope platform.

[0007] Furthermore, the slope ratio of the bank is 1:1, the width is 1m, and there are stairs on the slope of the bank.

[0008] Furthermore, the pond slope protection structural material is light-proof and water-impermeable material.

[0009] Furthermore, the main body of the breeding pond has an area of ​​1 mu to 2 mu, a width of 15m to 17m, and a depth of 1.5m.

[0010] Furthermore, the pool bottom is shaped like a turtle's back.

[0011] The beneficial effects of the utility model are:

[0012] (1) In actual use, the width of the breeding pond is appropriate, and there is no need to row a boat in the pond for feeding. You can just walk around the pond and feed directly; the area of ​​a single pond is appropriate, which relatively reduces the economic losses caused by disease outbreaks. The pond bank has a secondary slope platform, which is also a feeding platform for feeding, which can effectively reduce the waste of feed sinking into the mud and is also convenient for observing the feeding of river crabs; in addition, the secondary platform is also an operating platform for fishing, which is more convenient and effective than operating in the mud at the bottom of the pond. In addition, by setting a turtle-back-shaped pond bottom, drainage is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0019] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] See also Figure 1-Figure 3 The present application proposes a crab pond structure, including a breeding pond body 1, a bank 2 is arranged inside the breeding pond body 1, a pool bottom 3 is arranged below the bank 2, a water inlet 4 is arranged on one side of the breeding pond body 1, and a water outlet 5 is arranged on the other side.

[0021] See also Figure 1-Figure 3, Breeding pond body 1: area between 1 mu and 2 mu, width between 15m and 17m, depth 1.5m.

[0022] The pond bank 2: includes a bank slope 201, a secondary slope platform 202 and a pond slope protection 203. The bank slope 201 has a slope ratio of 1:1, and the secondary slope platform 202 is flush with the pond bottom and has a width of 1m. A staircase 6 is provided on the bank slope 201, which is convenient for users to enter the inside of the breeding pond body 1 through the staircase 6 and observe the internal situation of the pond at close range. The pond slope protection 203 can protect the bank and the secondary slope platform 202. The slope protection material is made of opaque and impermeable material. The slope protection material needs to extend vertically into the pond bottom soil for more than 0.3m to ensure thorough pond protection and prevent crab seedlings from digging holes on the slope, resulting in the collapse of the crab pond or the inability of some crab seedlings to escape.

[0023] Pool bottom 3: Soil, relatively flat, turtle-back shaped.

[0024] Water inlet 4: Located on one side of the short side of the breeding pond body 1, within 0.5m from the upper end of the pond bank 2 in the vertical direction.

[0025] Water outlet 5: located at the other side of the short side of the breeding pond body 1, and vertically located at the bottom of the pond. The water outlet 5 is provided with an escape-proof net to prevent the crab seedlings from escaping.

[0026] For example, an existing breeding farm uses the breeding pond structure described in the utility model. In terms of operation, the workload is reduced, the number of breeding members is reduced, and it is convenient to observe the feeding situation of river crabs. Usually, a river crab breeding pond produces an average of 300 catties of river crabs per mu. The same breeding team can achieve a yield of 1,000 catties per mu by using the breeding pond described in the utility model.

[0027] To sum up, with the help of the above-mentioned technical scheme of the utility model, when in use, the width and area of ​​the crab pond described in the utility model are appropriate, which relatively reduces the economic losses caused by disease outbreaks, and by setting up the secondary slope platform 202, it can effectively reduce the waste of feed sinking into the mud, and it is also convenient to observe the feeding of river crabs; in addition, the secondary slope platform 202 is also an operating table during fishing, which is more convenient and effective than operating in the mud part 3 at the bottom of the pond.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
