Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Example 1

The embodiment provides a screening fishing tackle for catching procambarus clarkia, as shown in fig. 1, it includes ground cage body 1 and framework 2, ground cage body 1 plays the fishing effect, framework 2 plays the screening effect, it is specific, the afterbody of ground cage body 1 is for having the collection cage 11 of opening 111, framework 2 is established to opening 111's outside cover, opening 111 sets up glossy leading-in board to framework 2 bottom, do benefit to the crayfish of catching to get into in framework 2 from the ground cage smoothly, collection cage 11 and framework 2 can be realized being hoisted to upper portion in the water through support frame 3 and the string rope 31 of fixing above-mentioned, thereby do benefit to the observation of catching of procambarus clarkia, support frame 3 fixed insertion pond bottom can. The frame body 2 is a fishing net structure wrapped by a steel reinforcement framework, the mesh size of the fishing net structure is adaptive to the specification of a certain required procambarus clarkii so that the target procambarus clarkii is retained in the frame body 2, the small procambarus clarkii can pass through the mesh and return to the original pool without going through the process of manually fishing and then returning, and mechanical damage and stress reaction are avoided. Preferably, set up depth sensor 4 on support frame 3, depth sensor 4 sets up in framework 2 top and sends the depth of water information to PLC controller 5, and depth sensor 4 monitors the depth of water from the top is perpendicular downwards, can measure the depth of water information that the surface of water was arrived to the cray in the framework 2, and depth sensor 4 sends PLC controller 5 with depth of water information, can judge whether collected the cray of sufficient quantity in the framework 2. Preferably, the depth sensor 4 faces the middle portion of the first frame 21 to transmit the information of the water depth in the first frame 21 to the PLC controller 5, and the water depth in the first frame 21 gradually decreases as the number of procambarus clarkia increases, and when the water depth decreases to a set value, it indicates that sufficient procambarus clarkia is stacked in the first frame 21, and the next step of moving out and transferring can be performed. And the received depth information is sent to an intelligent terminal 6 such as a mobile phone, a computer and the like to the PLC 5, so that the depth information is convenient to read.

Further, the support frame 3 comprises an electric telescopic cross rod 32 and a longitudinal rod 33, the depth sensor 4 is arranged on the electric telescopic cross rod 32, and the longitudinal rod 33 is fixedly arranged on the water bottom. According to the position condition of framework 2, the position of the depth sensor 4 can be adaptively adjusted through the electric telescopic cross rod 32, the flexibility is improved, and the monitoring accuracy is guaranteed. Better, electronic flexible horizontal pole 32 and servo motor 8 electric connection, through servo motor 8's accurate control ability, satisfy the position adjustment demand of electronic flexible horizontal pole 32.

Furthermore, the frame body 2 comprises a first frame body 21 and a second frame body 22 which are connected with the hanging rope 31, the second frame body 22 is sleeved outside the first frame body 21, and the mesh of the second frame body 22 is smaller than that of the first frame body 21, so that the procambarus clarkia of different target specifications is respectively retained in the first frame body 21 and the second frame body 22, the in-situ subdivision of the procambarus clarkia specification is realized, the manual sorting link is reduced, and the survival rate of the procambarus clarkia is ensured. Preferably, the hanging rope 31 is an elastic rope, when the procambarus clarkia climbs into the first frame 21 and the water body obviously overflows, the hanging rope 31 can stretch or shake properly, so that the procambarus clarkia is stacked in the first frame 21 and uniformly distributed, and the accurate monitoring of the depth sensor 4 is facilitated.

Furthermore, this screening fishing tackle still sets up offset adjustment disk 7, and offset adjustment disk 7 is connected with the bottom of frame 2 through elasticity stay cord 73, and when frame 2 squinted, can utilize offset adjustment disk 7 to correct under the effect of rivers. Specifically, 2 through holes 71 are symmetrically arranged on the biasing adjusting disk 7, a fastener 72 is arranged on one side of the biasing adjusting disk 7 facing the frame 2, one end of an elastic pull rope 73 is connected to the bottom of the frame 2, the other end of the elastic pull rope 73 penetrates through the through hole 71 far away from the elastic pull rope 73 to be connected with the fastener 72, and the other elastic pull rope 73 is also arranged in the same way. When the bottom of the frame body 2 inclines, the elastic pull rope 73 is pulled to simultaneously drive the clamping piece 72, so that the inclined state of the deviation adjusting disc 7 changes, at the moment, water flows through the deviation adjusting disc 7 to reversely apply pressure to the deviation adjusting disc 7, the deviation adjusting disc 7 is gradually adjusted to the original state, and the crayfishes inside the frame body 2 are uniformly distributed. Preferably, the latch member 72 may be a cover plate, a baffle plate, a long rod having a length greater than the inner diameter of the through hole 71. The 2 through holes 71 are provided in one set, and 2 or more sets may be provided on the bias adjustment plate 7 to accommodate the deflection state of the frame body 2.

When the crayfish catching device is used for catching crayfish, the crayfish enters the frame body 2 through the ground cage body 1 and is accumulated in the frame body 2, due to the mesh difference between the first frame body 21 and the second frame body 22, the crayfish with larger specification is retained at the upper layer, the crayfish with smaller specification is retained at the lower layer, and the crayfish which does not meet the requirement of landing can escape through the meshes of the frame body 2 and automatically returns to the pool. When crayfish in the framework 2 increases gradually, the depth data fed back by the depth sensor 4 will be smaller and smaller, and the crayfish in the framework 2 can be collected in time according to the feedback of the PLC controller 5 or the intelligent terminal 6. If the crayfish in the framework 2 distributes unevenly, the bottom of the framework 2 can incline, the elastic pull rope 73 and the clamping piece 72 can displace at the moment, so that the inclined state of the deflection adjusting disc 7 changes, the water flow and the pulling force of the elastic pull rope 73 can act on the deflection adjusting disc 7 in a reverse direction, the inclined state of the framework 2 is further adjusted, the uniform distribution of the crayfish is promoted, and the monitoring accuracy of the depth sensor 4 is ensured.
