A controllable buoyant system (10) includes a support structure having a sealed hollow enclosure (12) containing a first gas and surrounded by a second gas, either the first gas or the second gas being lighter than ambient air. The hollow enclosure is pre-filled with the first gas via a one-way valve that prevents the first gas escaping and an altitude sensor (14) generates an altitude signal indicative of a height of the support structure. A height transducer (17, 21, 61, 66, 67, 68) coupled to the hollow enclosure is responsive to the altitude signal for varying the buoyancy of the support structure. A controller (15) is coupled to the altitude sensor and to the height transducer and is responsive to the altitude signal and to at least one reference altitude signal for automatically controlling the height transducer in order to maintain the support structure buoyant at the preset altitude.

An improved floating boat lift incorporates a passive hydraulic pivoting lift mechanism, onto which a boat can be driven and positioned ready for storage using only the motive power of the boat itself. The passive hydraulic pivoting lift mechanism provides mechanical advantage in the pivoting action of the apparatus by way of passive hydraulic action, while at the same time dampening pivoting of the apparatus. Embodiments further provide means for adjusting the elevation of the pivot point relative to the surface of the body of water by way of adjusting the buoyancy of the pivoting lift mechanism.

The invention discloses a light-transmitting fishing float and a light-emitting fishing float. The light-transmitting fishing float comprises a float body and a light guide bar. The light guide bar penetrates through the float body from top to bottom, the portion, above the float body, of the light guide bar serves as a float tail, the portion, located in the float body, of the light guide bar serves as a float shaft, and the portion, below the float body, of the light guide bar serves as a float foot. The light-emitting float comprises the light-transmitting fishing float and a light emitter. A light guide bar connector is formed in the light output end of the light emitter, and the float foot is inserted into the light guide bar connector. The light-transmitting fishing float can be independently used as a fishing float, a complete light guide light path is arranged in the light-transmitting fishing float, and the light-transmitting fishing float can be used at night during fishing in cooperation with the light emitter. The light-emitting fishing float replaces the form of a built-in electronic element of an original fishing float, and the light emitter of the light-emitting finishing float further has the function of a balance weight. In addition, due to the fact that a buoyancy adjusting device is mounted on the light emitter, the light-emitting fishing float has the function of adjusting buoyancy, a battery bin of the light emitter has the function of a charging socket, and therefore the light-emitting fishing float has the function of the balance weight and the function of adjusting buoyancy.

A fishing line accessory comprises a body having an internal compartment which can be sealed with a cap. The compartment, when empty allows the fishing line accessory to function as a float. The compartment can be filled with sand to allow the same accessory to function as a sinker. The compartment can be partially filled with sand / water to allow the degree of buoyancy of the accessory to be varied in an almost unlimited manner.

The present invention is a variable light fishing lure comprised of a plastic housing with an internal cavity for holding a submergible lighted element and an angled aperture for inserting the lighted element into the cavity. A plug is inserted into the angled aperture to prevent the lighted element from falling out of the housing. Water can be added to plastic housing before inserting the plug to adjust the buoyancy of the fishing lure. The outside of the plastic housing contains a striated pattern which allows light from the lighted element to shine through the housing. The lighted element can be easily removed from the housing and replaced with the same or another color lighted element.

The invention provides a fish cage device for deep-sea culture with adjustable buoyancy, which relates to the field of marine culture equipment, and includes a buoyancy tank. The body is provided with a buoyancy control mechanism. When the buoyancy-adjustable deep-sea culture fish cage device needs to sink below the sea surface, by opening the first electromagnet assembly and the second electromagnet assembly, and the first electromagnet assembly and the second electromagnet assembly are facing the side of the buoy. The magnetic pole is the same as that of the permanent magnet facing the first electromagnet assembly and the second electromagnet assembly. At this time, under the repulsion of the same pole, the permanent magnet will be subjected to a repulsion inward, so that the permanent magnet drives the piston plate to push inward , so that the sea water enters the buoy, at this time the buoyancy provided by the buoy decreases, and the whole device will move down until it hovers a certain distance below the sea surface, at this time it can avoid the wind on the sea surface, thereby protecting the entire fish cage, very easy to use convenient.
