Description

Technical Field

[0001] The invention relates to popular science demonstration equipment, in particular to a buoy demonstration device. Background Art

[0002] The Argo float is an oceanographic instrument used in the field of earth science. From top to bottom, the Argo float has an antenna and a CTV sensor on the top. The antenna can use satellite systems such as the Beidou satellite to transmit data. The CTV sensor can observe the temperature, salinity and pressure of seawater. A balance plate is also provided on the upper part of the buoy, which can help the buoy maintain a basically vertical state on the sea. Components such as a controller, an oil pump and a battery are installed in the body of the float. A bladder is installed at the bottom of the buoy. When the oil pump fills oil into the bladder, the bladder expands, thereby increasing its volume and buoyancy, thereby causing the buoy to float. Conversely, when the oil pump draws the oil back from the bladder, the volume of the bladder decreases, the buoyancy decreases, and the buoy will dive.

[0003] There is no popular science device in the prior art specifically used to demonstrate the working principle of the Argo float. Summary of the invention

[0004] In view of the above problems, the present invention provides a buoy demonstration device.

[0005] The technical solution adopted by the present invention is as follows: A buoy demonstration device comprises a hollow transparent column and a buoy model arranged in the hollow transparent column; The hollow transparent column has a liquid storage cavity arranged up and down, and the liquid storage cavity is used to store water or salt water; The buoy model includes: A transparent cylindrical shell has a sealed space inside, and a mounting groove is provided at the lower end of the transparent cylindrical shell; A first oil pump assembly is installed in the sealed space; a first oil bag, installed in the installation groove, the first oil bag being connected to the first oil pump assembly via a first pipeline that passes through the transparent cylindrical housing in a sealed manner; A battery is installed in the sealed space and is used to supply power to the buoy model.

[0006] The present application changes the volume of the first oil bag through the first oil pump assembly, thereby changing the buoyancy of the buoy model and enabling the buoy model to rise or dive in the liquid storage chamber; the transparent cylindrical shell and the hollow transparent column can facilitate personnel to watch the action process, thereby achieving more intuitive science popularization teaching.

[0007] When used in practice, the device also includes a remote controller and a controller located in the buoy model, and the controller has a wireless transceiver module.

[0008] In one embodiment of the present invention, the outer wall of the transparent cylindrical shell has an annular groove, and the buoy model further includes: A second oil pump assembly is installed in the sealed space; An annular elastic oil bladder is embedded in the annular groove. The inner side of the annular elastic oil bladder is connected to the second oil pump assembly through a second pipeline that seals and passes through the bottom wall of the annular groove. The annular elastic oil bladder has a contracted state and a convex state. When the annular elastic oil bladder is in the contracted state, the annular elastic oil bladder is completely located in the annular groove. When the annular elastic oil bladder is in the convex state, the annular elastic oil bladder expands outward to form an annular structure that protrudes from the annular groove.

[0009] The second oil pump assembly and the annular elastic oil bag cooperate with each other to simulate the structure of the Argo float balance plate, and can easily compare the difference in the rise and dive of the float model with and without a balance plate, which is convenient for popularizing the role of the balance plate.

[0010] In one embodiment of the present invention, a wireless charging mechanism is further included, and the wireless charging mechanism includes: A charging coil, located in the sealed space and electrically connected to the battery; A first movable seat is movably disposed at the lower part of the liquid storage chamber, and a wireless charging unit is installed on the first movable seat. When the first movable seat is adjacent to the charging coil, the battery can be charged; The first telescopic element, the movable rod of the first telescopic element is slidingly and sealably arranged on the hollow transparent column, and the end of the movable rod of the first telescopic element is fixed to the first movable seat.

[0011] This arrangement enables the buoy model to be charged by wireless charging without the need to take out the buoy model for charging.

[0012] In actual use, the movable rod of the first telescopic element is a hollow rod. After the cable seal of the electronic component on the first movable seat passes through the movable rod of the first telescopic element, it passes through the part of the movable rod of the first telescopic element located outside the hollow transparent column.

[0013] In one embodiment of the present invention, when the bottom of the buoy model contacts the bottom wall of the liquid storage chamber, the wireless charging unit and the charging coil are at the same horizontal position.

[0014] In one embodiment of the present invention, a first gear is provided at a lower position on the outer side of the transparent cylindrical housing, and the wireless charging mechanism further includes: a second movable seat, movably disposed at the lower part of the liquid storage chamber, on which a driving gear and a motor assembly for driving the driving gear to rotate are installed, wherein the driving gear is used to cooperate with the first gear; and A second telescopic element, wherein a movable rod of the second telescopic element is slidably and sealably disposed on the hollow transparent column, and an end of the movable rod of the second telescopic element is fixed to the second movable seat; The first movable seat and the second movable seat both have arc-shaped surfaces on one side facing the buoy model. When the first movable seat and the second movable seat are brought close to each other, the buoy model can be confined between the two arc-shaped surfaces, and at this time the driving gear and the first gear are meshed with each other.

[0015] In actual use, the movable rod of the second telescopic element is a hollow rod. After the cable seal of the electronic component on the second movable seat passes through the movable rod of the second telescopic element, it passes through the part of the movable rod of the second telescopic element located outside the hollow transparent column.

[0016] In one embodiment of the present invention, the transparent cylindrical shell has a magnet, and the second movable seat has a control circuit for controlling the operation of the motor assembly, and the control circuit includes a Hall sensor. When the position of the magnet corresponds to the position of the Hall sensor, the charging coil is aligned with the wireless charging unit.

[0017] A specific working form of the wireless charging mechanism: the buoy model dives to the bottom (the bottom of the buoy model contacts the bottom wall of the liquid storage chamber), and then the first telescopic element and the second telescopic element work, so that the first movable seat and the second movable seat are close to each other, and the buoy model can be confined between the two arc-shaped surfaces, and at this time the driving gear and the first gear are engaged with each other, and the motor assembly works, and the buoy model is driven to rotate through the engagement of the driving gear and the first gear until the magnet on the transparent cylindrical shell corresponds to the position of the Hall sensor, and at this time the charging coil is aligned with the wireless charging unit, and accurate wireless charging can be performed.

[0018] In one embodiment of the present invention, the first movable seat and the second movable seat both have a hard part and an arc-shaped elastic part located on both sides of the hard part. The arc-shaped surface is located on the hard part, and the arc-shaped elastic part is used to play a guiding role, so that the buoy model can be transferred between the two hard parts when the first movable seat and the second movable seat are close to each other.

[0019] In one embodiment of the present invention, the bottom of the liquid storage chamber has two avoidance grooves, and the two avoidance grooves correspond to the first movable seat and the second movable seat one by one. In the initial state, the hard parts of the first movable seat and the second movable seat are respectively located in the corresponding avoidance grooves.

[0020] If no avoidance groove is provided, the movable seat will occupy a larger space at the bottom of the liquid storage chamber. When the buoy model dives to the bottom, it is easy to fall directly above the hard part, causing the wireless charging mechanism to fail to work properly.

[0021] In one embodiment of the present invention, the upper end of the transparent cylindrical housing further has an antenna portion.

[0022] In one embodiment of the present invention, the upper end of the transparent cylindrical housing further has a sensor portion.

[0023] The beneficial effects of the present invention are as follows: the present application changes the volume of the first oil bag through the first oil pump assembly, thereby changing the buoyancy of the buoy model, and realizing the rise or dive of the buoy model in the liquid storage chamber; the transparent cylindrical shell and the hollow transparent column can facilitate personnel to watch the action process, thereby realizing more intuitive science popularization teaching.

[0040] In actual use, the movable rod of the second telescopic element 28 is a hollow rod. After the cable seal of the electronic component on the second movable seat 27 passes through the movable rod of the second telescopic element 28, it passes through the part of the movable rod of the second telescopic element 28 located outside the hollow transparent column 1.
