Abstract

PURPOSE:To generate a requisite group of bubbles at a desired depth by providing an underwater depth controlling screw to be connected to a pressure vessel, a control box for detecting the depth by water pressure and controlling a motor for driving the screw, etc. CONSTITUTION:The pressure value detected by a pressure transducer 7 is inputted to an analog memory 11. The set value of a timer can be previously obtained from a relational diagram between the depth of the submerged generator and time. When the generator lowers below the reference values or the water pressure increases, a relay 13 is actuated, the screw 15 set at the upper of the generator is rotated in the normal direction by a motor 14, and the generator is raised. When the generator is raised above the reference value, the screw 15 is rotated in the reverse direction, and the generator is lowered. The starting and direction of rotation of the screw 15 are controlled by a combination of a deviation computing element 12 and the relay 13.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The invention relates to a device for forming groups of small bubbles in water, and in particular to the structure of a device for forming groups of small bubbles while maintaining a defined depth.

<Prior art and its problems> The structure of a conventional underwater bubble generator is shown in FIG. A conventional underwater bubble generator includes a bubble generating container1. Air bubble outlet throttle, valve 2. It is composed of a water inlet check valve 3 and a bubble generating chemical 4. When this device is released into water at an arbitrary depth, a required amount of water 5 flows into the device from the water inlet check valve 3. It reacts with the bubble-generating chemical 4 in the bubble generator 1 to generate bubbles such as hydrogen gas.

However, when this device is initially released into the water, it descends underwater due to the weight of the injected water and the container, and once the container is filled with gas, it rises due to buoyancy, making it difficult to use it at the target depth at which it was released. There's a problem.

<Problems to be Solved by the Invention> The above-mentioned conventional technology does not have a function to control the depth level at any depth at which the underwater bubble generator is discharged into the water. There was a problem in that it was not possible to generate a group of small bubbles.

<Object of the invention> This invention rotates the screw in the normal direction so as to maintain the depth level of the device when the device that generates bubbles is released into the water.
It is an object of the present invention to provide a device that can control underwater pressure as a signal to reverse the problem.

Overview of Means for Reacting> The present invention provides a pressure-resistant container containing a chemical that reacts with water to form a group of small bubbles, a water inlet reverse valve connected to the container, a bubble outlet throttle valve connected to the container. The bubble generating device is characterized by comprising a screw for adjusting underwater depth, and a control box that detects the underwater depth using water pressure and controls a motor that drives the screw.

<Example 1> Fig. 1 is a longitudinal sectional view showing the groove structure of an underwater bubble generator with depth control according to the present invention, and Fig. 2 is a flow sheet of the equipment in the control box.

Part numbers 1 to 15 indicate parts that constitute the depth control groove.

The underwater bubble generator with depth control function of the present invention is constructed by attaching parts number 6 to 15 to a conventional underwater bubble generator. By installing a depth control four-way groove, the conventional underwater bubble generator has the ability to maintain the specified depth and generate bubbles without ascending or descending at any depth at which the device is discharged. It is something.

The depth control device 6i1 of the underwater bubble generator with depth control function of the present invention is discharged into the water and generates bubbles at a desired depth. Detect the pressure at that point. The water inlet valve 3 can be opened at a depth shallower than a specified depth depending on the water pressure it receives. This can also be adjusted before applying the compressive force of the spring device that closes the valve. Further, the operation of supplying water from this artificial valve may be such that the valve is always open even if the underwater depth changes, for example, the membrane may be perforated with a needle or the like using water pressure.

Alternatively, it may be opened by a command from the depth control device (control box) 6. Further, the bubble outlet throttle valve 2 may be opened by a timer (mechanically) or by a command from the depth control device 6.

The pressure value detected by the pressure transfer unit 7 is manually entered into the analog memory 11 as a base value. Note that the set value of the timer can be obtained in advance from a relationship diagram between depth and time after injection.

When the device falls below the base +11 value, that is, when the water pressure increases, the relay 13 is activated and the motor 14 rotates the screw 15 installed at the top of the device in the forward direction to start the device. raise Further, when the device rises relative to the reference value, the screw 15 is rotated in the reverse direction to lower the device.

This can be done by controlling the starting and rotating direction of the scree 15 using a combination of the deviation calculator 12 and the relay 13. An amplifier 8 and a battery 9 are provided as necessary components of the depth control mechanism at the bottom.

<Other Examples> If it is desired to generate bubbles at a certain rise or fall position from the specified depth, this can be done by providing a deviation in advance to the pressure reference value detected by the depth control mechanism of this device. Become.

If necessary, the water inlet check valve 3 can be used as a valve for controlling the amount of water flowing in, and its opening can be controlled using a water pressure value as a signal.

Depth control device @6 installed at the top of the underwater bubble generator detects the depth at the time of discharge into the water using water pressure as a reference pressure, and when the device rises or falls below the specified depth, the depth control device @6 is installed at the top of the underwater bubble generator. The device is level-controlled at a desired depth by detecting the deviation value of water pressure and rotating the screw installed in the depth control mechanism forward or backward.

This depth control mechanism allows the underwater bubble generator to generate a group of bubbles while maintaining the target discharge depth of the device without ascending or descending.

Effects> By carrying out the present invention, it is possible to control the level of the underwater bubble generator to be located at a constant depth in the water from which it is released without ascending or descending from the underwater depth from which it was released. can generate the required group of bubbles at the target depth.

Furthermore, since bubbles can be generated at the target depth, the bubbles generated from the limited amount of chemicals can be used efficiently, and the design of the device, including the amount of chemicals in the device, can be made accurately and easily, reducing the use of wasted chemicals. This has the effect that there is no need to take extra time for this.
