Description

Underwater oxygen supply fish luring device

Technical Field

The utility model belongs to the technical field of fishing equipment, concretely relates to oxygen suppliment fish luring device under water.

Background

Fishing is a recreational activity and has been documented as early as the early days of the beginner. In the fishing process, factors influencing the fishing amount include air pressure, temperature, position, fishing tackle, bait, fishing skill and the like.

From a technical point of view, it is most important that no more fish can be continuously gathered at the fishing point. As summarized by aquatic science and technology workers in long-term practice, dissolved oxygen is a necessary condition for fish to live, and the amount of dissolved oxygen in water has a great influence on the food intake of the fish. When the dissolved oxygen in water is more than 5mg/L, the fish ingests normally; when the dissolved oxygen amount is reduced to 4mg/L, the food intake of the fishes is reduced by 13 percent; when the dissolved oxygen amount is reduced to 2mg/L, the food intake of the fishes is reduced by 54 percent, and some fishes are difficult to survive; when the concentration of the fish drops below 1mg/L, the fish stops eating. Therefore, the dissolved oxygen of water is a key factor for determining whether the fish eats the bait, and the direct relation is how much the fish catches.

In order to solve the problem of the oxygen content in water, fishing enthusiasts generally adopt a nest making device or an oxygen supply device to promote the oxygen content in water at a fishing point, attract more fishes to gather at the fishing point, and promote the fishing success rate. Patent publication is CN 204168917U's utility model patent, discloses an oxygenation camera shooting fishing ware under water, its including float gas-liquid mixing device on the water surface of water, establish immersible pump, the liquid dispersion device of distribution aperture under water, camera, power, the immersible pump lead to pipe respectively with gas-liquid mixing device and liquid dispersion device connect, the camera is established on the liquid dispersion device, the power is gas-liquid mixing device, immersible pump and camera power supply. Although this patent solves the problem of aquatic oxygen content through the gas-liquid mixture device that floats on the water surface of water, current oxygen suppliment device nevertheless has following defect:

(1) the existing oxygen supply device adopts the oxygen supply pump to supply oxygen underwater, the water depth of fishing is usually 2-4 m, due to the influence of water resistance and water pressure and air pressure, the purpose of improving the underwater local dissolved oxygen content can be achieved only by conveying enough air to 2m or even deeper underwater, however, the output pressure of the direct current oxygen supply pump on the market can not meet the existing requirement, even if the requirement of the output pressure is met, enough air is directly output from the water bottom, the generated air bubbles can continuously explode in the ascending process of the water, the fish school can be threatened by the explosion sound, and the fishing efficiency is influenced.

(2) Although current apparatus of oxygen supply adopts the water that the gas-liquid mixing device direct feed pump contains gas, be used for the oxygen suppliment under water, however the size of the aquatic dissolved oxygen volume can't be adjusted to this gas-liquid mixing device (this gas-liquid mixing device inhales water, gaseous structure is fixed, only absorb water and gas among the gas-liquid mixing device through the suction of immersible pump), and can not use under the relatively poor environment of weather (for example strong wind weather, the gas-liquid mixing device that floats on water is difficult to fix in an area within range, when gas-liquid mixing device removed, drive parts moving as a whole such as immersible pump easily, thereby lead to unable use).

(3) When current apparatus of oxygen suppliment was supplied oxygen, only can predict the size of aquatic dissolved oxygen volume through the content of oxygen pump or gas-liquid mixing device output air, unable direct observation to be difficult to accurate control aquatic dissolved oxygen volume's size, especially in rainy day or night, when needing to adjust aquatic oxygen content, be difficult to accurate regulation.

(4) The oxygen supply device has oxygen supplying joints set in the water outlet end and has diameter greater than that of the water outlet pipe, complicated underwater environment and easy jamming in water. In addition, current apparatus of oxygen supply sets up under water usually, not only collects the inconvenience, still has the potential safety hazard (the easy electric leakage of the electronic component in aqueous).

(5) The existing oxygen supply device has a complex structure, and is inconvenient for outdoor fishing and carrying.

(6) In order to increase the dissolved oxygen in water at the fishing spot, fishermen usually adopt an oxygen increasing agent, which easily causes environmental pollution.
