Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aquaculture, in particular to a detachable anti-escape baffle structure for crab farming. Background Art
[0002] Crabs belong to crustaceans and like to hide during the day and come out at night. In order to prevent crabs from escaping, an anti-escape board is set around the breeding pond. For example, a Chinese patent with the publication number CN214709638U and the name of "an anti-escape device for a crab breeding pond" includes an anti-escape board, and the smooth surface of the anti-escape board faces the crab breeding pond; the bottom of the anti-escape board is buried under the soil surface around the crab breeding pond; a support elbow pipe is arranged on the side of the anti-escape board; the bottom of the support elbow pipe is inserted on the soil surface around the crab breeding pond, and the anti-escape board is pressed above the support elbow pipe to form a flanging facing the crab breeding pond. Although the anti-escape board with this structure can prevent crabs from escaping, it is easy to be blown down in windy weather. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a detachable anti-escape baffle structure for crab farming in view of the above-mentioned prior art deficiencies.
[0004] To solve the above technical problems, the technical solution adopted by the utility model is:
[0005] A detachable anti-escape baffle structure for crab farming includes a pre-embedded base. One side of the surface of the pre-embedded base is provided with a connecting seat, and multiple baffle plates are arranged above the connecting seat. The baffle plates are rotatably connected through pins between the baffle plates and between the baffle plates and the connecting seat. A support frame is arranged on the pre-embedded base, and after the baffle plates are stretched and unfolded, they are supported by the support frame. The upper end of the support frame is connected with a pin socket, and after the baffle plates are stretched and unfolded, the upper ends are connected and fixed to the pin socket through pins.
[0006] Further, pin sockets are alternately arranged on the connecting seat and the side surface of the baffle plate, and the pins are inserted into the pin sockets.
[0007] Further, the support frame adopts a triangular support frame, and a positioning groove is processed on the pre-embedded base, and the bottom of the triangular support frame is inserted into the positioning groove.
[0008] Further, the outer sharp corners of the triangular support frame are rounded off.
[0009] Further, an avoidance opening for avoiding the pin socket is processed on the side surface of the triangular support frame.
[0010] Further, pin holes with square side holes on both sides are processed in the pin socket and the upper end of the baffle plate, and the pin includes a pin shaft, and a square locking piece is arranged at the front end of the pin shaft.
[0011] Compared with the prior art, a detachable anti-escape baffle structure for crab farming according to the present utility model forms an anti-escape baffle by stretching and unfolding the baffle. In the event of strong windy weather, the baffle is folded and fixed to prevent it from being blown down. After the strong wind, the baffle is unfolded again to prevent crabs from escaping.

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below.
[0019] As Figures 1 to 5 shown, a detachable anti-escape baffle structure for crab farming includes an embedded base 1. One side of the surface of the embedded base 1 is provided with a connection seat 2. Above the connection seat 2, there are multiple baffles 3. The baffles 3 are rotatably connected to each other and to the connection seat 2 through a pin shaft 4. A support frame 5 is provided on the embedded base 1. After the baffles 3 are stretched and unfolded, they are supported by the support frame 5. The upper end of the support frame 5 is connected with a pin seat 6. After the baffles 3 are stretched and unfolded, the upper ends are connected and fixed to the pin seat 6 through a pin 7.
[0020] In this embodiment, the embedded base 1 is made of rectangular steel pipes. During installation, the rectangular steel pipes are embedded in the ground. The connecting seat 2 is fixed on one side of the surface of the rectangular steel pipe by screws or welding. Pin seats 8 are staggered on the connecting seat 2 and the side surface of the retaining piece 3. Among them, the pin seat on the connecting seat 2 is made of a cut cylindrical pipe, and the cylindrical pipe is fixed on the connecting seat 2. The retaining piece 3 is made of a 0.5 mm stainless steel plate or a 1 mm polyethylene thin plate. When the retaining piece 3 is made of a 0.5 mm stainless steel plate, excess plates are first stamped on its side surface. The excess plates are wound and turned to form a row of outwardly protruding pin seats on one side and a row of inwardly concave pin seats on the other side. When the retaining piece 3 is made of a 1 mm polyethylene thin plate, the pin seats are formed by a mold. After the retaining pieces 3 are spliced together and the retaining pieces 3 and the connecting seat 2 are spliced together, the pin shaft 4 is inserted into the pin seat 8 so that the retaining piece 3 can be folded or stretched and unfolded.
[0021] The support frame 5 is a triangular support frame. The outer sharp corners of the triangular support frame are rounded off. A positioning groove 9 is processed on the embedded base 1. The bottom of the triangular support frame is inserted into the positioning groove 9 to position the triangular support frame by using the positioning groove 9. At the same time, the bottom of the triangular support frame is embedded in the ground.
[0022] An avoidance opening 10 is processed on the side surface of the triangular support frame to avoid the pin seats on the connecting seat 2 and the retaining piece 3.
[0023] Pin holes 11 with square side holes on both sides are processed in the pin seat 6 and the upper end of the retaining piece 3. The pin 7 includes a pin shaft 12. The pin shaft 12 is inserted into the pin hole 11. A square locking piece 13 is arranged at the front end of the pin shaft 12. By rotating the pin shaft 12, the square locking piece 13 is misaligned with the square side hole of the pin hole 11, and the upper end of the retaining piece 3 can be locked.
[0024] During normal use, the embedded base is arranged around the breeding pond. The retaining piece is stretched and unfolded and locked and fixed by the pin 7 to form an anti-escape baffle. When encountering strong winds of level 8 or higher, the river crabs take shelter in the waterweeds and caves. At this time, the pin 7 is pulled out, the retaining piece is folded, and the folded retaining piece is pressed by a heavy object. When the wind force weakens to level 2-3, the retaining piece 3 is unfolded to form an anti-escape baffle, so as to avoid the escape of river crabs caused by the repair of the baffle before.
[0025] The present invention is not limited to the described embodiments. Those skilled in the art can still make some modifications or changes without departing from the spirit of the present invention and within the scope of disclosure. Therefore, the scope of the protection of the present invention is subject to the scope defined by the claims.
