Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a fish and shellfish fry culture tank that is easy to disassemble and assemble.

(Conventional technology) Fish and shellfish, especially juvenile salmon, are often cultivated along the Sanriku coast and the Hokkaido coast, where the topography is complex and there are few flat areas. However, the dimensions of a fish and shellfish fry culture tank are 15m to 20m in length and approximately 60m in depth.
cm, and the width is about 150cm, so you need a large one,
Fixed-type fry culture tanks made of conventional concrete tanks, FRP tanks, etc. cannot be installed unless the land is leveled.

Furthermore, it is necessary to change the habitat conditions for young salmon as they grow, but it is difficult to move the salmon from one place to another in concrete tanks. For this reason, the installation site must be left in the same state as it is during the off-season, making it impossible to make effective use of the installation location.

Furthermore, in the case of a concrete tank, alkaline substances may be leached from the concrete, and in the case of an FRP tank, harmful substances such as styrene monomer may be generated, which may adversely affect the growth of young fish. In addition, in the case of concrete tanks, scratches may occur on the fish bodies.

Therefore, conventionally, assembling types that can be assembled and disassembled and are easily moved have been proposed (for example,
(Refer to Utility Model Publication No. 54-174599).

This consists of a large number of panels with vertical and horizontal bends formed on the four sides of a horizontally long metal plate, reinforcing rods fixed to the inside of the metal plate, and a connecting plate with a V-shaped cross section. and a synthetic resin sheet, the left and right bent portions of the metal plate are bolted together with a connecting plate interposed to form an enclosing frame, and the sheet is stretched within this enclosing frame, and This is a prefabricated fishpond in which the outer periphery of this sheet is fixed to the upper end of the enclosure frame.

(Problems to be Solved by the Invention) However, although the above-mentioned conventional technology can certainly be assembled and disassembled, it has the following problems.

That is, since the enclosure is formed of a plurality of panels, the entire surface of each panel receives the water pressure within the enclosure. Moreover, each panel is horizontally long. Therefore, when increasing the number of panels used to enlarge the fish pond, the water pressure applied to each panel increases exponentially, so it is necessary to use high-strength metal plates and reinforcing rods. Unless a separate support frame is prepared to support the enclosure from the outside, the panel will easily bend to the outside of the enclosure due to water pressure. However, increasing the rigidity of the panel as described above causes problems such as an increase in weight, the necessity of separately preparing a support frame, and an increase in cost. In particular, this has been a cause of greatly impairing the ease of installation and movement required for this type of device, as well as its economic efficiency.

Moreover, since the above-mentioned panel is the minimum structural unit of the enclosure frame together with the connecting plate, it cannot be disassembled any further. For this reason, when the enclosure frame is disassembled, the panel becomes bulky and heavy, making it difficult to transport or move it.

Furthermore, since the enclosure is intended to be formed by simply connecting panels, it is not stable in terms of strength. For this reason, there was a problem in that the lower end of the panel could not be installed unless it was buried in the ground, in addition to the use of a support frame as described above. This point is especially fatal when the installation is in a place where excavation is not possible.

The present invention was devised in view of the above-mentioned conventional problems, and is not only possible to disassemble and assemble, but also to be low-cost, and when disassembled, the weight of each component is small and bulky, making it easy to transport. The present invention aims to provide a fish and shellfish fry culture tank that is easy to move and install, and can be installed anywhere.

(Means for Solving the Problems) In order to achieve the above object, the fish and shellfish fry cultivation tank according to the present invention has a sheet-like material such as a canvas removably attached to the inside of a shape-retaining frame. The shape-retaining frame body is a tank, and the shape-retaining frame body includes a pair of side frames in which end pillars are erected at both left and right ends of the bottom material, and a center pillar is erected in the middle of the bottom material; A plurality of middle frames with end posts erected on both left and right ends, a plurality of through plates,
A plurality of Kasagi are the constituent elements, the pair of side frames are arranged in parallel, and the plurality of inner frames are arranged parallel to the side frames at appropriate intervals between these side frames. , the end posts at both the left and right ends of both side frames and each middle frame, and the end posts and center posts at both left and right ends of each side frame are dismantled and disassembled using the above-mentioned planks and caps, respectively.
They are connected so that they can be assembled into a box shape.

(Function) The shape-retaining frame body consists of a pair of side frames in which end posts are erected at both left and right ends of the bottom material, and a center post is erected in the middle of the bottom material, and a pair of side frames at both left and right ends of the bottom material. Its constituent elements are a plurality of inner frames with end posts erected thereon, a plurality of planks, and a plurality of caps, and each of the constituent elements is small and lightweight. Therefore, it can be easily transported and moved and installed.

The side frame has end posts erected at both left and right ends of the bottom material, and a center post erected in the middle of the bottom material; Since the frame is erected and a plurality of middle frames are placed at appropriate intervals between both side frames, the water pressure inside the shape-retaining frame is substantially equal to the number of end columns and middle columns. It will be accepted as such. As a result, water pressure within the shape-retaining frame is distributed. This also means that an increase in water pressure, that is, an increase in the size of the shape-retaining frame, can be coped with by simply increasing the strength of the end columns and middle columns attached to the bottom material, and the weight of the components increases. This also leads to lower cost increases.

In addition, the shape-retaining frame is formed into a box shape with each of the above components, and each of the side frames and the middle frame has a bottom material, so that it can firmly absorb water from the sheet-like object from below and from the sides. Can be done. Therefore, it is stable in terms of strength and can be installed anywhere.

Furthermore, since multiple inner frames are placed between the frames on both sides, the size of the shape-retaining frame can be changed freely to suit the situation at the site by simply changing the spacing between the frames. Can be done.
