Description

Intelligent ice-water amphibious fishing device

Technical Field

The invention belongs to the field of ice surface fishing, and particularly relates to an intelligent ice-water amphibious fishing device.

Background

In winter with extremely low temperature, the surfaces of rivers and lakes in some areas can be frozen into ice, on one hand, the ice surface becomes a new entertainment place, but even if the temperature is low, part of the ice surface can be frozen to be thin and is not suitable for bearing, the vehicle can fall into an ice cave due to the fact that the ice surface collapses in the process of parking on the ice surface or driving, on the other hand, the ice can be used as a resource with wide application, so that ice falling accidents occur in the process of commercial ice collection, and the first mode adopted by the existing method for salvaging falling ice objects is to lift the falling ice vehicle by using large rescue vehicles and equipment, but on the damaged ice surface, large salvaging equipment can operate on the ice surface, and more risks are likely to occur. The second mode is to use the slipway kickboard, utilizes strong magnetism location, salvages falling object to utilize the tractor to drag falling ice object out of the surface of water, but if the ice sheet is thick, the unable icebreaking of ship is close falling ice object, then this kind of mode can't be implemented. The existing fishing scheme is based on dragging in the process of dragging the falling ice object out of the water surface, the dragging of the falling ice object is very difficult at the junction of the ice surface and the water, secondary damage to the ice surface possibly causes dragging failure, the efficiency is low, and potential safety hazards exist, so that the safe intelligent ice surface fishing device needs to be invented urgently.

Detailed Description

The operation of the device of the present invention will be described in detail below with reference to the accompanying drawings.

According to experience, the motion track of the ice falling object before falling ice is from the thick ice layer to the thin ice layer, and when the thin ice layer can not support the weight of the ice falling object, the ice surface is broken, and the object falls into water. Therefore, the ice falling object is sufficiently supported on the thick ice side, and is dragged to the ice layer through the steel wire rope in the actual rescue process, and then the subsequent rescue operation is carried out. However, when the object falling ice is dragged to the boundary between ice and water, the ice surface will catch the object falling ice, so that the object falling ice cannot be dragged to the ice surface, and if the object falling ice is dragged forcibly, the ice surface will be cracked, resulting in greater loss. Therefore, the front crown block 1 of the present fishing device must be directed to the thick side of the ice layer, and the front crown block 1 must be positioned above the ice layer in order to place the falling ice object on the thick ice layer.

Before fishing begins, the distance between the left frame 3 and the right frame 17 is adjusted according to the size of the object falling into the ice, and the left frame and the right frame are fastened by screws after being adjusted. Salvage and divide two kinds of condition, the ice surface of the first kind of condition is very thick, control buoyancy motor 5 and rotate, drive through chain 7, make four buoyancy wheels 10 minor axes on the landing leg 4 downward, four backup pads 8 contact with the ice surface this moment, and whole fishing device all arranges in on the ice surface. The distance between the front lifting slide block 27 and the rear lifting slide block 26 is adjusted according to the length of the falling ice object, so that the falling ice object is not inclined in the fishing process. The lifting hook 11 and the rear lifting hook 12 respectively hook the front end and the rear end of the ice falling object, the hoisting motor 22 is controlled to rotate, and the lifting hook 11 and the rear lifting hook 12 are lifted upwards simultaneously until the ice falling object is completely separated from the water surface. The front pulling motor 16 is controlled to rotate, the front lifting slide block 27 and the rear lifting slide block 26 are pulled to slide forwards on the guide rail of the lifting beam 2 together, and then the ice falling object moves forwards together until the ice falling object moves above the ice surface, the ice falling object is placed on the ice surface, and the fishing process is completed. If in the process, one supporting plate 8 fractures the ice surface where the supporting plate is located suddenly, and the leg force sensor 19 detects that the pressure on the supporting leg 9 is rapidly reduced, the system controls the buoyancy motor 5 to rotate, the chain 7 drives the buoyancy wheel 10 to enable the long shaft to face downwards, the buoyancy wheel 10 enters water with the maximum volume, the maximum buoyancy is rapidly provided for the supporting leg 4 with the broken ice surface, and the whole fishing device is kept stable.

The second condition is that the ice surface is very thin or the ice surface is very broken, and the whole fishing device can only be placed in water. At the beginning, the buoyancy motor 5 is controlled to rotate, the chain 7 drives the buoyancy wheels 10 on the four supporting legs 4 to be downward in short axis, and at the moment, the volume of the buoyancy wheels 10 contacting water is the minimum, so that the minimum buoyancy is provided for the whole fishing device. In the fishing process, if the object to be fished is light in weight, the fishing is performed according to the fishing step of the first case. On the contrary, if the object to be salvaged is heavy, the four support legs 4 are stressed in the process of salvage, if the stress is not uniform, the support legs 4 with large stress may sink, so that the plane where the left frame 3 and the right frame 17 are located is inclined, at the moment, the electronic level meter 18 detects the sinking direction, the system controls the buoyancy motor 5 on the sinking support legs 4 to rotate according to the detection data, the volume of the buoyancy wheel 10 submerged in the water is gradually increased, and the buoyancy is gradually increased until the plane where the left frame 3 and the right frame 17 are located returns to the horizontal state. In addition, in the process that the object to be salvaged moves towards the direction of the front fixed pulley 1, when the object to be salvaged exceeds the range of the left frame 3 and the right frame 17, the pressure on the two supporting legs 4 at the back gradually changes to zero, at the moment, the state is a critical state, the object to be salvaged moves forwards again, and then the whole salvage device can turn over forwards. In order to ensure the stability of the device, when the frame force sensors 6 on the two rear supporting legs 4 detect that the pressure is zero, the system controls the water pump 13 to start to pump water to the water tank 14, the water tank 14 and the water in the water tank play a role of balance weight, when the device reaches balance, the water pump 13 stops pumping water, but as the salvaged object continuously moves forwards, the frame force sensors 6 on the two rear supporting legs 4 continuously detect that the pressure is zero, the water pump 13 also continuously starts to pump water until the salvaged object reaches the position above the ice surface, the water pump 13 stops pumping water, and when the salvaged object is placed on the ice surface, the water discharge hole 20 of the water tank 14 is opened to discharge the water. The fishing process is completed.
