Description

The utility model relates to controls for underwater devices and apparatuses and is intended for making contact closure inside sealed enclosures, devices and apparatuses under the influence of a magnetic field of a permanent magnet, accompanied by a diver underwater engineering works.

The invention is known "Switching device" (Application RU No. 2009123173, publ.: 12/27/2010), in which the switching device consists of a control panel, which is a mounting plate in the form of a matrix of n cells with magnetically sensitive elements located in them, placed in an explosion-proof enclosure of non-magnetic material and a contact drive in the form of a movable magnet into which an amplitude selector-shaper is inserted, magnetically sensitive elements are made in the form, for example, of Hall sensors, and the drive is in the form of contactless Permanent portable permanent magnet.

The disadvantage of this invention is the inability to work under water.

The invention is known "Signaling measuring device" (Patent No. US 5231508 (A), publ.: 1993-07-27), which presents an example implementation of a signaling measuring device with a hidden switch on the Hall effect, which is located on the front plate of the signaling device. There is a measuring mechanism 12 that responds to the measurement conditions 13. The measurement condition 13 can be represented by pressure, in the case of using a mechanism with a Bourdon tube, or electric potential, in the case of using a magnetoelectric measuring device. The mechanism 12 converts the value of the measurement condition into the rotational movement of the shaft 14 connected to the index arrow 15. A magnet is mounted on the index arrow so that its movement brings it closer to the Hall effect switch 10 to switch element 10. An example of a switch on the Hall sensor is given, which is mounted on an adjustable lever. The adjustable lever is connected to the adjustment handle passing through the transparent lens. The adjustable lever can be rotated to set the switching value of the signal measuring instrument. The magnet is connected to the arrow. The arrow rotates due to the movement of the shaft or rod, controlled by the mechanism of the measuring device (not shown). Alternatively, the arrow may be driven by a cranked lever and pivoted on a shaft in embodiments of the invention with a fixed shaft.

The disadvantage of this invention is the movement of the magnet in an arc of a circle, which leads to an increase in the size of the controls, the movement of the magnet in an arc increases the control time of the device and reduces the reliability due to the increase in the total interaction surface of the magnet and the Hall sensor, as well as the inability to work underwater.

This invention is the closest technical solution to the claimed technical solution, i.e. prototype.

The objective of this utility model is to provide the ability to work under water, increase reliability, simplify the device.

This problem is solved by creating an underwater magnetic button containing the movable part of the button, a base for mounting the movable part of the button on an airtight housing, a magnet with the ability to move, a Hall sensor in which the magnet is located in the movable part of the button, while the movable part of the button is located in the hole of the base, mounted on the surface of a sealed enclosure, on the inside of which on the same axis as the magnet is a Hall sensor.

Also, this problem is solved by creating a movable part of the button containing the housing, a magnet into which a shock absorber, a bezel, a latch are inserted, the housing being made coaxially with the central and annular internal recesses, the magnet being located in the central recess and the shock absorber in the annular, bezel located on the lower part on the outside of the case, and the latch is connected to the lower part of the rim.

In addition, the connection of the rim and the latch is made by bayonet engagement.

The utility model is illustrated by drawings.

Figure 1 is a drawing of an underwater magnetic button.

Figure 2 is a diagram of an electric underwater magnetic button.

The underwater magnetic button (Fig. 1) contains the movable part of the button 1, the base 2 for mounting the movable part of the button 1 on the sealed housing 3, the magnet 4 with the ability to move located in the movable part of the button, the Hall sensor 5, the movable part of the button 1 is located in the hole a base 6 mounted on the surface of the sealed enclosure 3, on the inside of which a Hall sensor is placed on the same axis with the magnet, thus the free movement of the magnet in the movable part of the button is guaranteed to cause a short circuit to opki and is guaranteed to make the circuit with a fully tempered button.

The movable part of the button 1 (Fig. 1), comprising a housing 7, a magnet 4, a shock absorber 8, a rim 9, a latch 10, while the housing 7 is made coaxially with the central and annular internal recesses, while the magnet 4 is located in the central recess, and the shock absorber 8 in an annular, rim 9 is located on the lower part outside the housing, and the latch is connected to the lower part of the rim 9.

In addition, the connection of the rim 9 and the latch 10 is made by bayonet engagement.

The device operates as follows.

To change the operating mode of the underwater vehicle, to set the coordinates of the underwater objects during the underwater technical work, the diver presses the corresponding buttons located on the lid of a sturdy case. The buttons are functionally grouped and optimally positioned so as to be within the range of the respective fingers.

When the movable part of the button 1 is pressed, the magnet 4 moves towards the sealed housing 3. When the magnet 4 approaches the surface of the sealed housing 3, the shock absorber 8 is compressed and the Hall sensor 5 is triggered. In this case, the current flows between the terminals of the Hall sensor “common” and “ output "(figure 2). When you release the button, the shock absorber 8 is expanded and moves the magnet 4 together with the moving part of the button to its original state. Hall sensor 5 also returns to its original state. The current flowing between the terminals “common” and “output” is terminated. For the penetration of the magnetic field of the magnet 4 into the sealed enclosure, it must be made of non-magnetic materials, for example, aluminum. In this case, the wall thickness of the casing is selected from the conditions for ensuring the strength of the casing when immersed to a predetermined depth and magnetic field penetration. For depths up to 120 m, the wall thickness of the sealed enclosure should be about 15 mm.

The underwater magnetic button is placed in the hole of the base 6, which is fixed on the sealed housing 3, the base can be made, for example, of plexiglas 3 mm thick and fixed with a latch 10.

Thus, this system allows you to control the product at depths of up to 120 m, to increase the speed and reliability of the device.
