Embodiment 1

[0022] Embodiment one, see figure 1 A variable buoyancy fishing tackle includes a flexible fishing tackle body 1 and an air pump switch 14 . The fishing tackle body 1 is a fishing net. The lower end of the fishing tackle body 1 is provided with several pendants 11 . The upper end of the fishing tackle body 1 is connected with several floats 12 . The fishing tackle body 1 is also provided with a waterproof box 13 . The float 12 includes an air bag 121 , an air storage tank 122 and an air pump 123 . The air bag 121 is connected with the fishing tackle body 1 together. The air tank 122 is a rigid structure. Both the air storage tank 122 and the air pump 123 are located in the air bag 121 and are fixed together with the air bag, specifically by bonding. The air pump 123 is a two-way air pump. The air inlet of the air pump 123 communicates with the inner space of the air bag 121 , and the air outlet of the air pump 123 communicates with the inner space of the air storage tan...

Embodiment 2

[0024]Embodiment 2 is different from Embodiment 1 in that the number of sinkers is equal to the number of floats, and one float 12 and one sinker 11 form a pair of floats 10 . The pendant 11 is provided with a pendant connecting structure 16 and a sling 17 . The length of the sling 17 is 8 meters. Sling 17 connects pendant 11 with fishing gear body. The pendant connecting structure 16 includes a first hanging ring 161 , a second hanging ring 162 and a cable 163 . The first suspension ring 161 includes a split ring 1612 with an opening 1611 at its lower end and a blocking rod 1613 . The upper end of the split ring 1612 is fixedly connected with the fishing tackle body. The blocking rod 1613 closes the opening 1611 . The lower end of the second suspension ring 162 is fixedly connected with the pendant 11 . The split ring 1612 is sleeved on the blocking rod 1613 .

[0025] The floating pendant pair 10 is provided with a cable driving mechanism 18 . The cable driving mechan...

Abstract

The invention relates to fishing tools. A variable-buoyancy fishing tool includes a flexible fishing tool body, a plurality of plummets connected to a lower end of the fishing tool body, and a plurality of floaters connected to an upper end of the fishing tool body; each floater includes an air bag ad an air pump switch, an air storage tank having a rigid structure and an air pump controlled by the air pump switch are arranged in the air bag, the air pump is a two-way air pump, an air inlet of the air pump communicates with an inner space of the air bag, and an air outlet of the air pump communicates with an inner space of the air storage tank; when the air bags of all the floaters are expanded, the sum of the generated buoyancy is greater than the weight of the fishing tool; the sum of the buoyancy generated by the air storage tanks of all the floaters is less than the weight of the fishing tool; and the sum of weights of all the plummets is greater than the sum of the weight of the fishing tool and the buoyancy generated by the air storage tanks. A position of the fishing tool in water can be changed, effort can be saved when the fishing tool is pulled out of water, and the problem that positions of the conventional fishing tools in water cannot be changed, and lots of time and effort must be cost when the conventional fishing tools are pulled out of water.

Description

technical field [0001] The application of the present invention relates to fishing gear, in particular to a variable buoyancy fishing gear. Background technique [0002] Existing fishing gear bodies that can be opened and folded (such as fishing nets, fishing tackle with multiple hooks) realize the opening of the fishing gear body by setting sinkers (also known as weights) and floats at the upper and lower ends of the fishing gear. The existing retractable and unfoldable fishing gear has the following disadvantages: it can only be positioned on the water surface in an upright manner (the buoyancy produced by the float is greater than the weight of the fishing gear and the weight of the pendant is greater than the weight of the fishing gear body) or at the bottom of the water ( When located at the bottom, the buoyancy produced by the float is greater than the weight of the fishing gear body and the weight of the pendant is greater than the weight of the fishing gear), that is...
