Description

Technical Field

[0001] The invention relates to the technical field of aquatic animal capture, in particular to a benthic animal capture device. Background Art

[0002] There are currently two common ways to capture benthic animals, namely draining the pond and using ground traps. Draining the pond is a feasible option for cleaning aquatic ponds and selling benthic animals, but draining the water is not appropriate in scenarios such as large-surface aquatic animal surveys, pond aquatic animal surveys, and pond harmful benthic animal cleaning. At this time, ground traps become the main method.

[0003] Some fishing net devices have been proposed in the prior art, such as fishing nets that can be adjusted to catch fish at different water levels and suspended fishing nets. However, these prior arts are not suitable for capturing benthic animals. On the one hand, it is difficult to accurately place the ground cage at the bottom of a pond of unknown depth; on the other hand, benthic animals live at the bottom of the water area, and the existing devices cannot automatically adjust the position to ensure that the fishing net is at the bottom of the water area, nor can they ensure that the device at the bottom of the pond does not fold and can function normally.

[0004] The existing technology cannot ensure that the fishing net is at the bottom of the water area, and cannot meet the needs of capturing benthic animals. In scenarios such as large-surface aquatic animal surveys, a device that can accurately sink to the bottom of the water area to capture benthic animals is needed. Summary of the invention

[0011] A ground cage, the top of which is connected to the coiled rope, and an entrance is arranged on the side wall of the ground cage;

[0012] A counterweight block is connected to the bottom end of the ground cage through a traction rope.

[0013] Preferably, the floating board is provided with a solar panel, a battery, an LED lamp, a waterproof switch and a timing switch; the solar panel and the LED lamp are electrically connected to the battery respectively; the waterproof switch and the timing switch are both used to control the opening and closing of the LED lamp.

[0014] Preferably, it further comprises an auxiliary rope threading device, wherein the auxiliary rope threading device is used to assist the spiral rope to pass through the second shell and all the friction rings;

[0015] The auxiliary rope threading device includes a cylinder, which includes a first sub-cylinder and a second sub-cylinder both of which are semi-cylindrical. The first sub-cylinder can be snap-connected with the second sub-cylinder to form the cylinder. A fixed ring is fixed in the first sub-cylinder, and the fixed ring is used for binding the spiral rope to fix the spiral rope.

[0016] Preferably, the length of the first sub-cylinder is greater than the length of the second sub-cylinder.

[0017] Preferably, the friction ring is made of rubber and has elasticity.

[0018] Preferably, the bottom end of the floating board is connected to a first hook via a suspension rope, the top end of the first shell is provided with a second hook corresponding to the first connecting rope one by one, one end of the first connecting rope is tied to the corresponding second hook, and the other end is tied to the first hook.

[0019] Preferably, the top of the second shell is detachably connected to the first shell via a first connecting rod, one end of the first connecting rod is detachably connected to the first shell, and the other end of the first connecting rod is detachably connected to the top of the second shell.

[0023] Preferably, the friction ring is connected to the second housing via a second connecting rod.

[0024] Compared with the prior art, the present invention has achieved the following technical effects:

[0025] The benthic animal capturing device of the present invention can realize the automatic sinking and stopping of the ground cage, ensure the unfolding state of the ground cage at the bottom of the water, ensure that the ground cage can accurately sink to the bottom of the water area, and improve the capturing efficiency of benthic animals.

[0026] Specifically, the friction ring inside the rope controller rubs against the coiled rope, and the friction force is used to lower and retract the coiled rope, so that the ground cage can automatically sink to the appropriate position and stop according to the depth of the water. There is no need to manually adjust the lowering depth of the ground cage, which improves the accuracy and efficiency of the ground cage placement.

[0027] Furthermore, the counterweight at the bottom of the cage ensures that the cage sinks. During the sinking process, the gravity of the cage is greater than the friction of the coiled rope and the friction ring and the buoyancy of the solar floating panel, so the coiled rope will be released from the coiling device; the cage is continuously lowered until the counterweight touches the bottom of the water area; when the counterweight touches the bottom of the water area, the gravity of the counterweight and the support force provided by the bottom of the water area offset each other. The entire device remains straightened due to the buoyancy of the floating panel. It is worth noting that this will keep the cage straightened, ensuring that the cage will not move downward and fold, providing a good entry channel for benthic animals and increasing the probability of capturing benthic animals.

[0028] Furthermore, for different water depths, especially large areas of water and deep water areas and waters of unknown depth, the device can automatically adjust the sinking depth of the ground cage, overcoming the problem that the prior art is difficult to accurately control the position of the ground cage in these situations.

[0029] Furthermore, the floating board is equipped with solar panels and batteries to provide power for the LED lights. When used at night, the LED lights provide light sources, which is convenient for observing and operating the device. At the same time, it avoids the situation where the LED lights cannot light up normally due to insufficient power conversion of solar panels on rainy days, thereby improving the reliability and applicability of the device.

[0030] Furthermore, the battery can be taken out and charged using a charger, which increases the convenience of use.

[0031] Furthermore, the coiled rope can be replaced with ropes of different specifications according to actual use requirements, thereby improving the flexibility and adaptability of the device and meeting different water environments and capture requirements.

[0032] Furthermore, the auxiliary rope threading device is composed of two semi-cylindrical sub-cylinders, which facilitates the winding rope to pass through the friction ring and improves the assembly efficiency of the device. The two sub-cylinders are one long and one short, and the winding rope can be quickly taken out through the gaps in the staggered positions of the sub-cylinders, which is convenient for maintenance and adjustment of the device.

[0033] Furthermore, the entrance on the ground trap is funnel-shaped, and benthic animals can easily find the entrance and enter the ground trap, but it is not easy for them to leave the ground trap through the entrance, thereby improving the capture efficiency of benthic animals.

[0034] Furthermore, the overall design of the device takes into account the living habits and capture needs of benthic animals. The capture probability of benthic animals is improved through the positioning of solar floating panels, night lighting of LED lights, reasonable structure of ground cages, and automatic sinking and stopping functions.

[0035] Furthermore, the present invention is applicable to different water environments such as small water areas, shallow water areas, large water areas and deep water areas, solving the difficulties of artificially placing ground traps in large water areas and deep water areas, and expanding the application scope of benthic animal capture.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The purpose of the present invention is to provide a benthic animal capturing device to solve the problems existing in the above-mentioned prior art and ensure that the ground cage can be accurately sunk to the bottom of the water area to improve the capturing efficiency of benthic animals.

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] like Figures 1 to 6 As shown, this embodiment provides a benthic animal capture device, comprising:

[0048] Floating board 1;

[0049] The rope coiling device comprises a first shell, a drum 4 arranged in the first shell, and a handle 5 arranged outside the first shell. The drum 4 is rotatably matched with the first shell. One end of the handle 5 is fixedly connected to the center of one end of the drum 4. The drum 4 can be driven to rotate by rotating the handle 5. A spiral rope 6 is wound on the drum 4. A rope release port 21 for the spiral rope 6 to pass through is arranged at the lower end of the first shell. The top end of the first shell is connected to the floating board 1 through a plurality of first connecting ropes 3.

[0050] The rope controller comprises a second shell 7 and a plurality of friction rings 8 sequentially distributed in the second shell 7 from top to bottom. All friction rings 8 are coaxial and respectively fixed to the second shell 7. The upper and lower ends of the second shell 7 are provided with openings. The second shell 7 is detachably connected to the first shell. The upper end opening of the second shell 7 is located directly below the rope release opening 21. The coiled rope 6 passes through the second shell 7 and all friction rings 8, and the coiled rope 6 is in friction contact with the friction rings 8.

[0051] A ground cage 10, the top of which is connected to the coiled rope 6, and an entrance 11 is provided on the side wall of the ground cage 10;

[0052] The counterweight block 12 is connected to the bottom end of the ground cage 10 through a traction rope 13.

[0053] The benthic animal capturing device of this embodiment rubs against the coiled rope 6 through the friction ring 8 inside the rope controller, and utilizes the friction force to realize the lowering and contraction of the coiled rope 6, so that the ground cage 10 can automatically sink to the appropriate position and stop according to the depth of the water area. There is no need to manually adjust the lowering depth of the ground cage 10, thereby improving the accuracy and efficiency of the placement of the ground cage 10.

[0054] In the optional scheme of this embodiment, it is more preferred that the floating board 1 is provided with a solar panel 15, a battery 17, an LED lamp 2, a waterproof switch 14 and a timer switch 16, the solar panel 15 and the LED lamp 2 are electrically connected to the battery 17 respectively; the waterproof switch 14 and the timer switch 16 are used to control the on and off of the LED lamp 2. When used at night, the LED lamp 2 provides light source, which is convenient for observing and operating the device, and at the same time avoids the situation that the LED lamp 2 cannot light up normally due to insufficient power conversion of the solar panel on rainy days, thereby improving the reliability and applicability of the device.

[0055] In the optional solution of this embodiment, it is more preferred to further include an auxiliary rope threading device, which is used to assist the spiral rope 6 to pass through the second shell 7 and all friction rings 8;

[0056] The auxiliary rope threading device includes a cylinder body, and the cylinder body includes a first sub-cylinder body 22 and a second sub-cylinder body 24, both of which are semi-cylindrical. The first sub-cylinder body 22 can be snapped with the second sub-cylinder body 24 to form a cylinder body. A fixed ring 23 is fixed in the first sub-cylinder body 22, and the fixed ring 23 is used for binding the spiral rope 6 to fix the spiral rope 6. The length of the first sub-cylinder body 22 is greater than the length of the second sub-cylinder body 24. The auxiliary rope threading device is composed of two semi-cylindrical sub-cylinder bodies, which facilitates the spiral rope 6 to pass through the friction ring 8 and improves the assembly efficiency of the device. The two sub-cylinder bodies are one long and one short, and the spiral rope 6 can be quickly taken out through the notches at the staggered positions of the sub-cylinder bodies, which is convenient for maintenance and adjustment of the device.

[0057] In the optional solution of this embodiment, it is more preferred that the friction ring 8 is made of rubber and has elasticity.

[0058] In the optional scheme of this embodiment, it is more preferred that the bottom end of the floating board 1 is connected to the first hanging buckle 19 through the suspension rope 18, and the top end of the first shell is provided with a second hanging buckle 20 corresponding to the first connecting rope 3 one by one, and one end of the first connecting rope 3 is tied to the corresponding second hanging buckle 20, and the other end is tied to the first hanging buckle 19.

[0059] In the optional scheme of this embodiment, it is more preferred that the top of the second shell 7 is detachably connected to the first shell through a first connecting rod 29, the top end of the first connecting rod 29 is detachably connected to the first shell through a bolt, and the bottom end of the first connecting rod 29 is detachably connected to the top of the second shell 7 through a bolt.

[0060] In the optional scheme of this embodiment, it is more preferred that the entrance 11 is funnel-shaped. The entrance 11 on the ground cage 10 is funnel-shaped, and benthic animals can easily find the entrance 11 to enter the ground cage 10, but it is not easy to leave the ground cage 10 through the entrance 11, thereby improving the capture efficiency of benthic animals.

[0061] In the optional scheme of this embodiment, it is more preferred that the top end of the ground cage 10 is connected to the upper suspension buckle 25 through the second connecting rope 26, and the spiral rope 6 is connected to the upper suspension buckle 25; the bottom end of the ground cage 10 is connected to the lower suspension buckle 28 through the third connecting rope 27, and the traction rope 13 is connected to the lower suspension buckle 28.

[0062] In an optional solution of this embodiment, it is more preferred that the friction ring 8 is connected to the second housing 7 via a second connecting rod 9 .

[0063] The specific method of using the benthic animal capture device of this embodiment is as follows:

[0064] (1) Device assembly:

[0065] Connect the floating board 1 to the rope coiling device through the first connecting rope 3, select a suitable coiling rope 6, turn on or off the waterproof switch 14 and the timer switch 16 on the solar floating board 1 according to actual use requirements, assemble the ground cage 10, and connect the counterweight 12 to the lower suspension buckle 28 through the third connecting rope 27;

[0066] Pass the coiled rope 6 through the rope controller:

[0067] Separate the first sub-cylinder 22 and the second sub-cylinder 24 in the auxiliary rope threading device, then tie one end of the coiled rope 6 to the fixed ring 23, and then clamp the first sub-cylinder 22 and the second sub-cylinder 24 together, so that the coiled rope 6 is located in the cylinder of the auxiliary rope threading device; then pass the auxiliary rope threading device through the second shell 7 and each friction ring 8 of the rope control device, so that the coiled rope 6 also passes through the rope control device, and then remove the auxiliary rope threading device, and tie the coiled rope 6 to the upper hanging buckle 25; it should be noted that, since the cylinder walls of the first sub-cylinder 22 and the second sub-cylinder 24 are relatively thin, the setting of the auxiliary rope threading device will not affect the subsequent contact between the coiled rope 6 and the friction ring 8;

[0068] (2) Placement of ground cage 10:

[0069] Select the water area where the cage 10 needs to be placed, and slowly put the cage 10 into the water; due to the action of the counterweight block 12 under the cage 10, the cage 10 will sink; during the sinking process, the gravity of the cage 10 sinking is greater than the friction force of the spiral rope 6 and the friction ring 8 and the buoyancy of the solar floating panel 1, so the spiral rope 6 will be released from the rope release port 21; continue to lower the cage 10 until the counterweight block 12 touches the bottom of the water area;

[0070] When the counterweight 12 contacts the bottom of the water area, the gravity of the counterweight 12 and the support force provided by the bottom of the water area cancel each other out. The whole device remains in a straightened state due to the buoyancy of the floating board 1, and the ground cage 10 does not move downward and fold. Benthic animals can enter the ground cage 10 through the funnel-shaped entrance 11 on the ground cage 10.

[0071] (3) Take out the ground cage 10:

[0072] After the cage 10 has been placed for a sufficient period of time, the floating board 1 is pulled up;

[0073] Since the distance between the rope coiling device and the floating board 1 is small, after the floating board 1 is pulled up, the rope coiling device can be pulled out of the water. After the rope coiling device is pulled out of the water, the handle 5 is rotated to drive the drum 4 to rotate, so that the spiral rope 6 is retracted into the rope coiling device, and at the same time, an upward pulling force is applied to the ground cage 10. The upward pulling force eventually offsets the gravity of the ground cage 10, the aquatic animals captured in the ground cage 10 and the counterweight block 12, so that the ground cage 10 can be taken out of the water; then the benthic animals in the ground cage 10 can be taken out.

[0074] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
