Description

Technical Field

[0001] This utility model relates to the field of rice-frog farming technology, and in particular to a multi-functional protective device for rice paddy-farmed black-spotted frogs. Background Technology

[0002] Rice paddy frog farming is an ecological agricultural model that combines rice cultivation with frog breeding, making full use of the water, food resources, and space advantages of rice paddies. For successful farming, it is necessary to select rice paddies with abundant water supply and convenient irrigation and drainage, reinforce the paddy dikes and install escape-prevention facilities, and release uniformly sized frog fry while controlling the density appropriately. Daily management requires maintaining clean water quality, supplementing with appropriate artificial feed, and implementing disease prevention and control measures. This model not only improves the overall benefits of rice paddies and increases farmers' income but also promotes the development of ecological agriculture, achieving the effect of "multiple uses of one field and a win-win situation for rice and frogs." Protective devices are necessary to prevent birds from entering and to prevent escape.

[0003] The patent with publication number CN213908037U mentions a simple device for rice-frog farming, belonging to the field of mixed farming technology. The device includes a rice-frog farming apparatus body, which comprises a water channel, a rice planting area, a frog farming area, and protective devices. The water channel runs through both the rice planting area and the frog farming area, with the rice planting area located on both sides of the water channel. The frog farming area includes a frog habitat and a feeding device. The frog habitat is located outside the rice planting area, and the feeding device is set on both sides of the rice planting area and the frog farming area. The protective devices include an escape-proof net, a predator-proof net, and a zipper. The escape-proof net surrounds the rice planting area and the frog farming area, while the predator-proof net covers the area above the rice planting area and the frog farming area. This utility model has a reasonable structure, is easy to manufacture, uses readily available materials, is low in cost, and is environmentally friendly, possessing significant promotional value.

[0004] The inventors have discovered at least the following problems in the prior art:

[0005] Existing multi-functional protective devices for rice paddy farming of black-spotted frogs are usually equipped with overhead nets and ground nets, which are used to prevent birds and escape, respectively. However, because black-spotted frogs are attracted to light, and because some areas of rice paddies are illuminated at night for monitoring purposes, black-spotted frogs will gather at the edge of the nets where there is light at night, which increases the probability that black-spotted frogs will stack up and cross the nets.

[0006] In addition, due to the small mesh size of the barrier net, its drainage capacity is limited. In the event of heavy rain, it is necessary to manually drain the water to prevent rainwater from washing away the barrier net.

[0007] Therefore, this solution provides a multi-functional protective device for rice paddy black-spotted frog farming to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to provide a multifunctional protective device for rice paddy black-spotted frog farming, in order to solve the problems existing in the prior art.

[0009] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0010] A multifunctional protective device for rice paddy black-spotted frogs includes a support mechanism, a protective net, a triggering mechanism, and a shielding mechanism. The shielding mechanism is located above two adjacent support mechanisms, and the triggering mechanism is located below two adjacent support mechanisms. The support mechanism includes a shaped support plate, a float, and a receiving seat fixedly connected to the top of the shaped support plate. A conical rod is fixedly connected to the bottom of the shaped support plate and inserted into the bottom surface. The protective net is attached to the outside of the support mechanism and connected to the top of the shaped support plate by a cable tie. A pressure block is placed above the outside of the protective net. The triggering mechanism includes a pressure plate and a bottom box distributed vertically. The two ends of the bottom box are fixedly connected to the shaped support plate, and the two ends of the pressure plate are tied with pull ropes. The shielding mechanism includes a winding shaft and a light-blocking curtain wound around the winding shaft. The two ends of the winding shaft are rotatably connected to the inside of the receiving seat.

[0011] Preferably, the outer side of the irregular support plate is provided with a water-containing cavity, and the inner side of the irregular support plate is provided with equidistantly distributed water inlet grooves. The water inlet grooves are connected to the water-containing cavity, and a drainage groove is fixedly connected to the periphery of the opening of the water-containing cavity.

[0012] Preferably, the water-containing cavity has limiting grooves on both inner side walls, the two ends of the float are slidably connected inside the limiting grooves, and a baffle plate is fixedly connected to one side of the float, the baffle plate fitting the opening of the water-containing cavity.

[0013] Preferably, ratchet wheels are provided on both sides of the receiving seat, and the ratchet wheels are fixed by a winding shaft. A connecting cavity is provided inside the receiving seat, and a slider is slidably connected inside the connecting cavity.

[0014] Preferably, a spring is provided on one side of the slider, the other end of the pull rope is attached to one side of the slider, and a locking block is fixedly connected to the other side of the slider, the locking block engaging with the ratchet.

[0017] The beneficial effects of this utility model are:

[0018] I. This utility model utilizes a support mechanism, a protective net, a triggering mechanism, and a shielding mechanism that work together. Through the linkage design of the triggering mechanism and the shielding mechanism, when the black-spotted frogs are attracted to the inner side of the protective net by the night light, the pressure plate presses down to trigger the pull rope to release the ratchet lock. The counterweight drives the light-blocking curtain to automatically unfold and block the light source, effectively preventing the black-spotted frogs from stacking and escaping due to phototaxis, while also preventing strong light leakage from interfering with the frogs' physiological rhythms.

[0019] II. This utility model, through the coordinated operation of the support mechanism, protective net, triggering mechanism and shielding mechanism, and the linkage structure of the water-containing cavity, water inlet trough and floating block of the irregular support plate, can automatically open the blocking plate when the rainwater level approaches, forming a rapid drainage channel. It can drain the accumulated water without manual intervention, prevent the protective net from failing or collapsing due to rainwater erosion, and ensure the stability of the device and the safety of the paddy field.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0035] This utility model provides a multi-functional protective device for rice paddy aquaculture black-spotted frogs, including a support mechanism 1, a protective net 2, a triggering mechanism 3, and a shielding mechanism 4. The shielding mechanism 4 is located above two adjacent support mechanisms 1, and the triggering mechanism 3 is located below two adjacent support mechanisms 1.

[0036] The support mechanism 1 includes a special-shaped support plate 11, a float 16, and a receiving seat 18 fixedly connected to the top of the special-shaped support plate 11. A tapered rod 5 is fixedly connected to the bottom of the special-shaped support plate 11, and the tapered rod 5 is inserted into the bottom surface.

[0037] The protective net 2 is attached to the outside of the support mechanism 1 and connected to the top of the irregular support plate 11 by cable ties. A pressure block 6 is placed on the outside of the protective net 2.

[0038] The triggering mechanism 3 includes a pressure plate 32 and a bottom box 31 distributed vertically. The bottom box 31 is fixedly connected to the two ends of the irregular support plate 11, and the two ends of the pressure plate 32 are tied with pull ropes 35.

[0039] The shielding mechanism 4 includes a winding shaft 41 and a light-blocking curtain 42 wound around the winding shaft 41. The two ends of the winding shaft 41 are rotatably connected to the inside of the receiving seat 18.

[0040] The protective net 2 is a 60-mesh fence as in the prior art, used to block the black-spotted frogs on the inside. In addition, a corrugated steel sheet fence is installed around the entire perimeter of the paddy field to block terrestrial predators. A sky net is installed at the top of the paddy field to prevent birds from entering the paddy field. The protective net 2 has holes at the drainage ditch 15 and the support seat 18, and is then connected to the irregular support plate 11 by clips.

[0041] In a further embodiment, a water-containing cavity 12 is provided on the outer side of the irregular support plate 11, and water inlet grooves 13 are provided on the inner side of the irregular support plate 11 at equal intervals. The water inlet grooves 13 are connected to the water-containing cavity 12, and a drainage groove 15 is fixedly connected to the periphery of the opening of the water-containing cavity 12.

[0042] In this embodiment, the size of the water inlet trough 13 is larger than the mesh size of the protective net 2, allowing rainwater to enter more directly; the drainage trough 15 expands outward, so that the protective net 2 can be easily connected to the outer periphery of the drainage trough 15 by cable ties and clips.

[0043] In a further embodiment, limiting grooves 14 are provided on both inner sidewalls of the water-containing cavity 12, and the two ends of the float 16 are slidably connected inside the limiting grooves 14. A baffle plate 17 is fixedly connected to one side of the float 16, and the baffle plate 17 fits the opening of the water-containing cavity 12.

[0044] In this embodiment, the float 16 can open the baffle 17 when rainwater reaches the water-containing cavity 12, so that the rainwater can flow directly to the outside and intervene in time, thereby cooperating with the manual opening of the drainage system in the paddy field for rapid drainage.

[0045] In a further embodiment, ratchet 44 is provided on both sides of the receiving seat 18, the ratchet 44 is fixed by the winding shaft 41, and a connecting cavity 19 is provided inside the receiving seat 18, and a slider 46 is slidably connected inside the connecting cavity 19.

[0046] In this embodiment, the receiving seat 18 has grooves at both ends, which are connected to the connecting cavity 19, so that the slider 46 can be connected to the external locking block 45. In addition, the irregular support plate 11 also has a connecting cavity 19 inside, so that the pull rope 35 can pass through and pull the slider 46.

[0047] In a further embodiment, a spring 47 is provided on one side of the slider 46, the other end of the pull rope 35 is attached to one side of the slider 46, and a locking block 45 is fixedly connected to the other side of the slider 46, the locking block 45 engaging with the ratchet 44.

[0048] In this embodiment, both the ratchet 44 and the locking block 45 are located on the outside of the receiving seat 18. The locking block 45 is used to prevent the ratchet 44 from rotating clockwise. During the day, the winding shaft 41 can be manually rotated counterclockwise to wind up the blackout curtain 42. The blackout curtain 42 is made of blackout fabric.

[0049] In a further embodiment, a counterweight 43 is fixedly connected to one end of the blackout curtain 42.

[0050] In this embodiment, the counterweight 43 can pull the blackout curtain 42 when the ratchet 44 is no longer restricted by the jamming block 45, thereby passively rotating the winding shaft 41 and unfolding the blackout curtain 42.

[0051] In a further embodiment, a uniformly arrayed array of limiting posts 33 is fixedly connected to the lower part of the pressure plate 32. The limiting posts 33 are inserted into the inner side of the bottom box 31, and a spring 34 is provided around the periphery of the limiting posts 33.

[0052] In this embodiment, a tube is fixedly connected inside the bottom box 31 to facilitate the insertion of the limiting post 33, while the spring 34 is used to lift the pressure plate 32.

[0053] The working principle of this utility model is as follows:

[0054] When the black-spotted frogs are attracted to the inside of the protective net 2 at night by the light, they crowd on top of the pressure plate 32, causing the pressure plate 32 to slowly move down. The pull rope 35 pulls the slider 46 to move. When the bottom of the pressure plate 32 is completely inside the bottom box 31, the locking block 45 at one end of the slider 46 will disengage from the ratchet 44, allowing the ratchet 44 and the winding shaft 41 to rotate. With the help of the counterweight 43 fixed at one end of the light-blocking curtain 42, the winding shaft 41 is forced to rotate clockwise, thereby loosening the light-blocking curtain 42 and blocking the light-transmitting protective net 2. At this time, the light will not be able to pass through the protective net 2, and the black-spotted frogs will not continue to gather there, thus preventing the black-spotted frogs from escaping after being piled up and damaging the protective net 2.

[0055] When a sudden downpour occurs and the water level exceeds the paddy field level, approaching the bottom of the irregular support plate 11, the rainwater will enter the interior of the water-receiving cavity 12, causing the float 16 to rise. This will then open the baffle plate 17, allowing the rainwater to directly reach the outside of the enclosure through the water-receiving cavity 12 and the drainage channel 15, thereby enabling real-time drainage and preventing losses.

[0056] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
