Description

Technical Field

[0001] The present application relates to the field of marine aquaculture technology, and in particular to a sea cucumber sampling frame. Background Art

[0002] During sea cucumber farming, sampling frames are used to collect sea cucumber samples regularly to monitor their growth, health or conduct biological research.

[0003] Furthermore, by measuring the number of sea cucumbers inside a sampling frame of standard size, the production density of sea cucumbers can be considered through the sampling frame per unit area.

[0004] Most of the existing sea cucumber sampling frames are flat frames made of lightweight materials. When divers carry them underwater, it is difficult to effectively fix the sampling frames due to their buoyancy. In addition, the flat frame sampling frames are difficult to hold during the measurement operation, which reduces the operational efficiency during underwater measurement operations. Utility Model Content

[0005] The purpose of this application is to provide a sea cucumber sampling frame that can be effectively fixed, facilitates underwater operations, and reduces operational difficulty.

[0006] In order to achieve the above object, the utility model provides a sea cucumber sampling frame, comprising a sampling frame, a sampling handle connected to the sampling frame, the sampling handle comprising a handle hollow tube, the sampling frame comprising a frame hollow tube, the handle hollow tube and the frame hollow tube having a lumen communicating with each other;

[0007] The weighted steel ball, the handle hollow tube includes an open tube opening at the end, and the weighted steel ball enters and exits the interconnected tube cavity of the sampling frame through the open tube opening.

[0008] In an optional embodiment, the sampling frame includes a square planar frame, the sampling handles are arranged opposite to each other on the planar frame, and a pick-up nut is screwed onto the open tube mouth.

[0009] In an optional embodiment, the frame hollow tube comprises an integrally connected square ring tube;

[0010] Alternatively, the frame hollow tube includes four tube segments of the same length, and the tube segments are spliced together to form the planar frame.

[0011] In an optional embodiment, the handle hollow tube is perpendicular to the planar frame, and the inner diameter of the handle hollow tube is not smaller than the inner diameter of the frame hollow tube.

[0012] In an optional embodiment, a connecting piece is provided at a corner of the planar frame, and the connecting piece includes a bend protection pipe;

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of the embodiments.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0036] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0037] The sea cucumber sampling frame in this application is mainly used to measure the sea cucumber parameter quantity per unit area. Specifically, by improving the structure of the sampling frame and adding necessary counterweight components and plug-in fixing components, the application disadvantages of the existing sampling frame are improved, the convenience during underwater operations is enhanced, and the operation difficulty is reduced.

[0038] Example 1

[0039] See also Figure 1 The sea cucumber sampling frame in the present invention has a main structure including a sampling frame 1. In order to facilitate operation, a sampling handle 2 is connected to the sampling frame 1. The sampling handle 2 can facilitate the diver to carry the sampling frame into the water, and is conducive to the gripping operation of the sampling frame, reducing the difficulty of operation.

[0040] The sampling handle 2 specifically includes a handle hollow tube 21 . The handle hollow tube 21 has at least a certain length to provide sufficient gripping space.

[0041] The sampling frame 1 includes a frame hollow tube 11. By connecting the handle hollow tube 21 with the frame hollow tube 11 and adding a counterweight steel ball 3 in the connecting tube cavity, the overall weight of the sampling frame can be increased, thereby overcoming the obstructive effect of buoyancy on the sampling frame during its submersion.

[0042] The sea cucumber sampling frame of the present invention includes both measurement application states and idle storage and transportation states. The use of the weighted steel balls 3 is primarily for the measurement application state, with the purpose of increasing the weight of the sampling frame. However, to ensure portability during the idle storage and transportation states, the weighted steel balls 3 do not need to be constantly placed in the sampling frame. The weighted steel balls 3 can be introduced into the interconnected tube cavity through the open nozzle 22 at the end of the hollow handle tube 21, and can also be poured out through the open nozzle 22, thereby meeting the usage requirements in different states.

[0043] The sampling frame 1 in this embodiment comprises a square planar frame, with sampling handles 2 positioned opposite to each other on the planar frame. Specifically, two sampling handles 2 are positioned opposite each other on the same side of the planar frame. To prevent the weighted steel ball 3 from rolling out of the interconnecting lumen, a nut 23 is threaded onto the open tube opening 22. This nut 23 effectively controls the opening and closing of the open tube opening 22, allowing the weighted steel ball 3 to be placed in and removed from the interconnecting lumen with a simple twisting operation.

[0044] Based on the construction of interconnected tubular cavities, the frame hollow tube 11 in this embodiment includes an integrally connected square ring tube 11a. The interior of the square ring tube 11a is an integrated connecting tubular cavity. The handle hollow tube 21 is perpendicular to the plane frame, which is convenient for the diver to hold. In order to form the interconnected tubular cavity of the sampling frame 1, the two sections of the tubular cavity of the handle hollow tube 21 are respectively connected to the integrated tubular cavity of the square ring tube 11a.

[0045] In order to enable the counterweight steel ball 3 to enter the interconnected tube cavity through the handle hollow tube 21, the inner diameter of the handle hollow tube 21 is not less than the inner diameter of the frame hollow tube 11. Preferably, the inner diameter of the handle hollow tube 21 is the same as the inner diameter of the frame hollow tube 11.

[0046] Furthermore, in order to strengthen the structure of the hollow tube 11 of the frame, connectors are provided at the corners of the planar frame, and the connectors include bend protection tubes 4 of a vertical structure.

[0047] The bending protection pipe 4 in this embodiment is sleeved on the corner portion of the square ring pipe 11a, which can enhance the bending resistance of the corner portion.

[0048] The sea cucumber sampling frame in this embodiment can increase the overall weight of the sampling frame, and is convenient for divers to hold, effectively reducing the difficulty of operation and improving measurement efficiency.

[0049] Example 2

[0050] See also Figure 2 The sea cucumber sampling frame structure in this embodiment is basically the same as the sea cucumber sampling frame structure in Example 1. The difference is that the hollow tube 11 of the sampling frame 1 includes four independent tube segments 11b of the same length, and the four identical independent tube segments 11b are spliced together to form a planar frame of the sea cucumber sampling frame.

[0051] In addition, the inner diameter of the handle hollow tube 21 is larger than the inner diameter of the frame hollow tube 11, which is convenient for taking, placing and pouring the weighted steel balls 3 into the interconnected tube cavity.

[0052] Furthermore, the bend protection pipe 4 in this embodiment is connected between different pipe sections 11b, and the lumens of different pipe sections 11b are directly connected to the lumens of the bend protection pipe 4, which can also achieve the technical effect of forming interconnected lumens.

[0053] Example 3

[0054] See also Figure 3 The sea cucumber sampling frame in this embodiment is based on the structure in Example 1, and the function of the sea cucumber sampling frame is expanded so that the sea cucumber sampling frame has the function of being plugged and fixed on the bottom of the water.

[0055] Specifically, the sampling frame 1 is provided with a support rod 5, which is disposed on either side of the planar frame along with the sampling handle 2. Furthermore, the support rod 5 and the sampling handle 2 are disposed on either side of the sampling plane of the sampling frame 1, so that the support rod 5 can be inserted into the water bottom when the sampling handle 2 is gripped and pressed downward.

[0056] Specifically, the present embodiment includes four support rods 5, each corresponding to a bend protection tube 4. The support rods 5 are reversibly mounted on the sampling frame 1. A reversing support wheel 6 is connected to the lower portion of the bend protection tube 4, and the base of the support rods 5 is connected to the reversing support wheel 6. This arrangement enhances the portability of the sampling frame. After being folded, the support rods 5 can be tightly attached to the flat frame, reducing the space occupied.

[0057] In order to facilitate the insertion of the support rod 5 under water, the insertion end of the support rod 5, that is, the bottom end of the support rod 5, is provided with an insertion cone 51. At the same time, in order to prevent the risk of damage caused by the insertion cone 51, the paired support rods 5 are flipped towards each other on the same side, so that the insertion cone 51 can be centered after folding to reduce external interference.

[0058] Further, combined with Figure 4 A limiting bending plate 7 is also connected to the lower part of the bending protection tube 4. The limiting bending plate 7 can limit the folding angle of the support rod 5 so that it can only rotate within a range of 90° on the folding plane, reducing the risk of deflection and tipping.

[0059] At the same time, a notch groove is provided on the limiting bending plate 7 for regulating the support rod 5. After the support rod 5 is folded down into place, the support rod 5 can be accommodated in the notch groove, which further helps the support rod 5 to maintain a vertical plug-in state and facilitates the plug-in operation.

[0060] It should be pointed out that by setting the support rod 5, the sea cucumber sampling frame can be positioned on the measurement standard surface in a fixed support state, without the need for the diver to press the sampling frame to the bottom of the water. The technical purpose of measuring sea cucumber parameters within the specified standard area can also be achieved.

[0061] In this embodiment, the inner diameter of the handle hollow tube 21 is the same as the inner diameter of the frame hollow tube 11. In order to reduce the jamming of the counterweight steel ball 3 in the interconnecting tube cavity, the diameter of the counterweight steel ball 3 is not less than 1 / 2-4 / 5 of the inner diameter of the handle hollow tube 21 and the frame hollow tube 11 to avoid the deposition and clogging of small particles of the counterweight steel ball 3 in the interconnecting tube cavity.

[0062] In order to reduce manufacturing costs and enhance portability, the sampling frame 1 in the present invention is made of PVC.

[0063] The sea cucumber sampling frame in the present invention is a sampling frame 1 of standard size. Preferably, the side length of the sampling frame 1 is 1 m or 0.5 m, so as to facilitate the measurement operation of unit area under standard size.

[0064] The sea cucumber sampling frame in the utility model can reduce the difficulty of operation to the greatest extent and effectively improve the measurement efficiency.

[0065] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.

[0066] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
