Description

A deep sea ballast release device

technical field

The invention relates to a device for releasing heavy ballast installed on deep-sea operation equipment, and is especially suitable for ballast release of underwater robots and deep-sea engineering machinery.

Background technique

Existing devices for underwater dumping mostly use fuses, electric squibs, and balls to release ballast. The methods of fuses and squibs have poor reusability, and parts must be replaced after each use. The ball method has limited load capacity and is difficult to use in deep sea due to sealing problems, and its reliability is difficult to guarantee for heavier ballast release. The underwater dumping device is necessary for underwater operation equipment, and its reliability and economy need to be satisfied.

Contents of the invention

The invention provides a deep-sea ballast release device, which solves the problems that the existing load-throwing device is difficult to reuse, has a small load capacity, and is difficult to adapt to the full sea depth.

A deep-sea ballast release device, comprising a bracket, is characterized in that the bracket is provided with an electric solenoid assembly composed of a deep-sea electric solenoid and an electric solenoid plunger, and is composed of first and second levers The two-stage lever release assembly, the first and second-stage levers can respectively rotate around their respective fulcrums on the bracket in the vertical plane, the key point of the first-stage lever is constrained by one end of the electric solenoid plunger, and the first-stage The force point of the lever is the key point of the second stage lever, and the force point of the second stage lever is the ballast suspension point.

The technical effect of the present invention is embodied in that: the driving part of the deep-sea ballast release device is a deep-sea electric solenoid, and the transmission mode is a two-stage lever transmission; the first-stage lever and the second-stage lever cooperate with each other to reduce The longer resistance arm is obtained in the space, and the release of the ballast is controlled by a small power after the electric solenoid is energized, which is safe and reliable. The invention has a simple and compact structure, can be used repeatedly, can be used in the whole sea depth, is resistant to pressure and corrosion, can reliably carry and release 100Kg of ballast, and has a short response time, and is especially suitable for ballast release of underwater robots and deep-sea engineering machinery . Users can repeatedly achieve reliable recovery of deep-sea operation equipment with only a small amount of installation time.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

Fig. 1 is a typical implementation state of the present invention, which includes an electric solenoid assembly, a two-stage lever release assembly and a ballast assembly. The electric solenoid assembly includes a deep-sea electric solenoid 1 and an electric solenoid plunger 2. The deep-sea electric solenoid 1 with mounting screw holes is installed on the bracket 3 through screws, and the electric solenoid plunger 2 is connected from the bracket 3. The round hole on the top sticks out. The two-stage lever release assembly includes a bracket 3, a first-stage lever 4, a second-stage lever 5 and corresponding pin shafts, and both the first-stage lever 4 and the second-stage lever 5 are mounted on the bracket 3 through the pin shafts. The ballast assembly includes a hemispherical contact ball 6 , a screw 8 and a disc ballast 7 .

When the present invention is used for dumping the underwater robot, holes are drilled on the support 3 and fixed to the underwater robot. Insert the electric solenoid plunger 2 in the released state into the deep-sea electric solenoid 1, then place the first-stage lever 4 and the second-stage lever 5 as shown in Figure 1, and then hang up the ballast. When in use, the electric solenoid assembly is installed on the two-stage lever release assembly, and presses the key point of the first-stage lever through its plunger, and the ballast is mounted on the second-stage lever through its hemispherical contact ball. When the electric solenoid works, the plunger of the electric solenoid is quickly sucked back, the lever group loses its resistance, and the two-stage levers start to move under the gravity of the ballast; when the second-stage lever rotates At 90°, the ballast is separated from the deep sea ballast release device.

As shown in FIG. 2 , there are two mounting screw holes on the end face of the deep-sea electric solenoid 1 for fixing it on the bracket 3 .

As shown in Figure 3 (A), the two-stage lever release assembly of the present invention includes a bracket 3, a first-stage lever 4, a second-stage lever 5 and a pin shaft, and the two pin shafts respectively connect the first-stage lever 4 and the second-stage lever 5 is installed on the support 3, and both the first-stage lever 4 and the second-stage lever 5 can rotate vertically with the corresponding pin shaft as the center of circle.

As shown in Figure 3 (B), the bracket 3 of the present invention is a stainless steel part, and the upper and lower sides are respectively welded with support seats for installing the electric solenoid assembly, the first-level lever 4 and the second-level lever 5, and there is a long bracket in the middle of the bracket 3. strip holes.

As shown in Fig. 3 (C) and Fig. 3 (D), the present invention can set a guide groove at the lower end of the first stage lever 4, and the end of the second stage lever 5 will slide in the guide groove when releasing ; The upper end of the first-stage lever 4 is welded with a stopper, which plays an axial positioning role on the electric solenoid plunger 2 .

As shown in Fig. 3 (E), the end of the second stage lever 5 of the present invention is upturned, and its upturned angle and height can make the whole set of equipment within the range of pitching 45°, and the ballast assembly will not slide out by itself.

The deep-sea ballast release device can reliably carry and release 100kg of ballast according to the experimental measurement. In the case of a load of 100kg, the response time from the signal received by the electric solenoid to the release of the ballast is ≤200ms. In the case of protection, the ballast components will not slide out by themselves within the overall pitch range of 45° of the underwater equipment. The invention can be directly immersed in the deep sea to work, and can work normally in the environment with a depth of 1000m.
