Description

Technical Field

[0001] The present invention relates to the technical field of data storage, and in particular to a shipborne ship data recording and storage device. Background Art

[0002] Ship data recording and storage equipment, namely ship data recorder (commonly known as "black box"), is a special device installed on ships, mainly used to continuously record various key data during navigation. These data include the ship's position, speed, heading, rudder angle, main engine speed, ship status and communication records. The main purpose of the black box is to provide important information before and after the accident when the ship has an accident, so that accident investigators can analyze the cause of the accident and determine the responsibility. Since a large amount of important data is stored in the black box, it needs to be protected. For example, a black box storage box disclosed in application number 202223393321.1 is used to protect the black box;

[0003] In order to ensure the security and reliability of data, existing black boxes may be equipped with both mechanical hard drives and solid-state drives. The mechanical hard drives are used for data storage, while the solid-state drives are used as backup storage to prevent the mechanical hard drives from failing in extreme situations. The two hard drives can work at the same time and store data synchronously in real time to ensure that the data can still be completely saved when any hard drive fails.

[0004] The existing shipborne ship data recording and storage equipment (black box) is usually fixed directly near the bridge. This location is mainly chosen to facilitate operators to easily check the status of the equipment and ensure that important audio and data information in the bridge area can be captured. However, fixing the black box directly on the bridge may not be the best choice, because the marine environment is extremely complex and often faces challenges of strong winds and huge waves. These natural conditions will cause the ship to shake violently, which in turn causes the black box to be subjected to frequent vibrations. Long-term vibrations may not only damage the internal components of the black box, but may also cause the equipment's fixings to loosen, eventually causing the black box to fall off. Once the black box falls off, the internal mechanical hard disk or solid-state hard disk will be damaged, especially the mechanical hard disk. Since the mechanical hard disk stores information based on the relative movement between the recording medium and the transducer, it is necessary to pay attention to the shock absorption of the black box. Summary of the invention

[0018] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0019] 1. Mechanical vibration is converted into electrical energy through piezoelectric ceramic sheets. When the ship is shaken by bumps, the piezoelectric ceramic sheets are squeezed or stretched, thereby generating current. This current is amplified and passed into the first electromagnetic plate. By adjusting the repulsive force of the first electromagnetic plate on the first permanent magnet plate, the suspension height of the support plate is adjusted. At the same time, the current is also passed into the second electromagnetic plate, so that the second permanent magnet plate drives the damping plate to squeeze the support plate, and the vibration energy is dissipated through the friction between the support plate and the damping plate. In this way, when the ship encounters bumps, the impact of vibration on the black box can be significantly reduced to protect it from damage.

[0020] 2. When encountering continuous turbulence, the support plate and the damping plate will rub for a long time. The continuous friction will generate heat, which will affect the friction effect. Therefore, a heat conductive strip and a temperature difference conductive rod are set in the damping plate to generate current by using the temperature difference. When the damping plate dissipates vibration energy and generates heat through friction, the temperature difference conductive rod uses this temperature difference to generate current. The current is used to control the reverse electromagnetic pressure valve to adjust the fluid pressure in the outlet pipe. When the friction temperature is high, the fluid pressure in the outlet pipe is increased to provide additional damping effect; when the friction temperature is low, the fluid pressure is reduced. In this way, through the synergistic effect of the temperature difference conductive rod and the semiconductor refrigeration plate, when the ship encounters long-term turbulence, it can provide additional shock absorption effect and further protect the black box from damage.

[0021] 3. When the ship tilts, gravity makes the counterweight point in the tilt direction. The detection rod slides on the resistance ring and identifies the tilt direction through the PLC controller according to the preset current value. In the initial state, the electric telescopic rod has squeezed the telescopic plate downward to fix the black box. After detecting the tilt, the PLC controller starts the electric telescopic rod in the corresponding direction to further squeeze the airbag to enhance the fixation of the black box to cope with the tilt of the ship caused by the reverse force. When the ship tilts, by further tightening the black box, it can effectively prevent it from shifting or being damaged due to the movement of the ship, thereby ensuring the security and integrity of the data.

[0031] The present invention will be further described below in conjunction with the embodiments.

[0035] Among them, the shock absorbing mechanism 3 also includes a vibration cavity 38 opened on the inner bottom wall of the storage frame 1, and the piezoelectric ceramic piece 31 is arranged in the vibration cavity 38. The piezoelectric ceramic piece 31 is electrically connected to a current amplifier 39. The current amplifier 39 is electrically connected to the first electromagnetic plate 35 to form a first shock absorbing circuit. The support plate 32 is made of magnetic isolation material, and the contact position between the support plate 32 and the damping plate 372 has wear-resistant particles. The current amplifier 39 is electrically connected to the PLC controller 16 to form a control loop. The current amplifier 39 is usually designed to amplify current signals. They usually contain current-voltage conversion circuits and amplifier circuits inside, which can process input current signals and output amplified current signals. The internal circuit may include a feedback loop to ensure that the output current is amplified proportionally to the input current.

[0036] The black box 33 can be further damped by the following specific structure. Figure 3 The damping assembly 37 includes a second electromagnetic plate 373 fixedly connected to the inner wall of the movable groove 371, a second permanent magnet plate 374 that magnetically repels the second electromagnetic plate 373 is fixedly connected to the outer wall of the damping plate 372 close to the second electromagnetic plate 373, two symmetrical connecting springs 375 are fixedly connected between the damping plate 372 and the movable groove 371, and the current amplifier 39 is electrically connected to the second electromagnetic plate 373 to form a second damping circuit.

[0037] Among them, a heat-conducting strip is arranged inside the damping plate 372, and a temperature difference conductive rod 310 is fixedly connected to the outer wall of the damping plate 372 near the connecting spring 375, and the heat-conducting strip is in contact with the hot end of the temperature difference conductive rod 310. The outer wall of the storage frame 1 is fixedly connected to the refrigeration shell 311, and the inner bottom wall of the refrigeration shell 311 is embedded with a semiconductor refrigeration plate 312. The cold end of the temperature difference conductive rod 310 airtightly penetrates the storage frame 1 and extends to the outside of the storage frame 1. The outer wall of the storage frame 1 is fixedly connected to a temperature-conducting sleeve 313 for airtightly protecting the cold end of the temperature difference conductive rod 310, and the temperature-conducting sleeve 313 is in the refrigeration shell 311.

This phenomenon is based on the Seebeck effect. When the junctions of two different materials are at different temperatures, electromotive force (voltage) will be generated, thereby forming current. The reverse electromagnetic pressure valve 315 is a device that controls fluid pressure by electromagnetic force. The reverse electromagnetic pressure valve 315 is normally open;

[0038] It is usually composed of an electromagnetic coil, a valve core and a valve body. When the electromagnetic coil is energized, the electromagnetic force generated will drive the valve core to move, thereby changing the valve opening and further adjusting the fluid pressure. The fluid pressure of the reverse electromagnetic pressure valve 315 is exactly opposite to that of the forward electromagnetic pressure valve. When the reverse electromagnetic pressure valve 315 is energized with a larger current, the electromagnetic force is stronger, the valve core moves a larger distance, the valve opening increases, and the fluid pressure increases. Conversely, the fluid pressure decreases.

[0043] The top of the removable cover plate 2 is fixedly connected with a connecting pipe 12 and an air outlet pipe 13. A normally open solenoid valve 14 is arranged in the air inlet pipe 11. A second one-way valve 15 is arranged in the air outlet pipe 13. The PLC controller 16 is electrically connected with the two-way exhaust pump 5 and the normally open solenoid valve 14 to form a temperature control loop.

[0044] The working principle of the present invention is as follows:

[0045] When a ship encounters strong winds and huge waves while sailing, it may cause the ship to pitch up and down or tilt left and right, or tilt forward or backward;

[0046] Whichever of the above situations occurs, vibration will be generated, and the vibration will be transmitted to the storage frame 1, thereby causing the piezoelectric ceramic sheet 31 to vibrate. The reason why the piezoelectric ceramic sheet 31 generates current when vibrating is because they have a special physical property called "piezoelectric effect". The piezoelectric effect refers to the fact that when certain materials are subjected to mechanical stress (such as pressure or tension), they will spontaneously produce charge separation, thereby generating voltage on the surface of the material. The current generated will be passed into the current amplifier 39, and then the amplified current will be immediately transmitted to the first electromagnetic plate 35. Since the generated current is proportional to the output current, and the vibration magnitude is proportional to the current magnitude, the vibration magnitude is directly related to the output current magnitude. When the vibration is strong, the greater the current passed into the first electromagnetic plate 35, the greater the repulsion of the first electromagnetic plate 35 to the first permanent magnet plate 36 (the reason is that by raising the support plate 32, the support plate 3 2, there is more time to consume energy and reduce vibration during the downward reset process), so that the support plate 32 drives the black box 33 to rise higher. On the contrary, when the vibration is weak, the support plate 32 drives the black box 33 to rise to a smaller height. The first electromagnetic plate 35 is powered on temporarily. When the first electromagnetic plate 35 cannot feel the repulsive force of the first permanent magnet plate 36, it can be stopped. The power-on time is the time when the black box 33 can move to the top of the storage frame 1 to prevent the black box 33 from moving upwards insufficiently. When the time is reached, the current amplifier 39 is controlled by the PLC controller 16 to cut off the power to the first electromagnetic plate 35;

[0047] At the same time, the amplified current is also transmitted to the second electromagnetic plate 373, and the repulsive force of the second electromagnetic plate 373 on the second permanent magnet plate 374 causes the damping plate 372 to squeeze the support plate 32. The stronger the vibration, the greater the squeezing of the support plate 32. On the contrary, the squeezing of the support plate is weaker. The elastic force and vibration of the damping spring 34 will cause the support plate 32 to drive the black box 33 to reset downward, and then the friction between the damping plate 372 and the support plate 32 will consume the kinetic energy of the support plate 32, and its kinetic energy will be converted into other forms of energy, such as heat energy, thereby reducing the vibration intensity transmitted to the black box 33. In addition, the damping spring 34 can provide a certain displacement buffer to absorb the vibration energy and reduce the transmission of the vibration. Even if the energy is not completely consumed during the descent, the elasticity of the damping spring 34 will cause the support plate 32 to move upward and continue to consume energy.

[0048] When encountering continuous bumps, the support plate 32 and the damping plate 372 will rub for a long time, and the continuous friction will generate heat. If the heat accumulates too much, it may cause deformation or damage of the material, thereby affecting the performance of the shock absorption system and reducing the shock absorption effect. Therefore, during friction, the heat is transferred to the hot end of the temperature difference conductive rod 310 through the thermal conductive strip, and then the cooling water in the refrigeration shell 311 is cooled and cooled through the semiconductor refrigeration plate 312, and then the cooling end of the temperature difference conductive rod 310 is cooled through the thermal conductive sleeve 313. The hot end of the temperature difference conductive rod 310 receives the heat generated by friction through the thermal conductive strip, while the cold end is cooled by the thermal conductive sleeve 313 and the semiconductor refrigeration plate 312. Due to the temperature difference between the hot end and the cold end, the temperature difference conductive rod 310 will generate a voltage difference, thereby driving the current, and then transmit the generated current to the current amplifier 39, and then transmit the current to the reverse electromagnetic pressure valve 315 through the current amplifier 39, thereby closing the reverse electromagnetic pressure valve 315. The degree of closure is controlled by the magnitude of the current generated by the temperature difference conductive rod 310. Therefore, when the temperature of the damping plate 372 is high, the temperature difference of the temperature difference conductive rod 310 is large and the current generated is large. Therefore, the degree of closure of the reverse electromagnetic pressure valve 315 is large, so the fluid pressure is large. Since the temperature is high, it proves that the friction of the damping plate 372 is large, so additional shock absorption is required. Therefore, when the support plate 32 is squeezed downward and moved, the air below needs to be squeezed. Since the air outlet of the air outlet pipe 314 is small, the resistance to the support plate 32 is large, which further assists in shock absorption.

[0049] When the ship tilts left or right, tilts up front or back, gravity will cause the counterweight 493 to point to the tilted side, and the other side of the detection rod 492 will slide on the resistance ring 495, and then the current at various places of the resistance ring 495 tested in advance will be compared with the current passing through the sliding rheostat detected by the PLC controller 16 to determine the direction in which the ship is tilted. In the initial state, the telescopic plate 410 has been pushed downward by the electric telescopic rod 48 to squeeze the airbag 45, and then the squeezing block 44 is squeezed to further fix the black box 33. After the tilt of the ship is detected, the PLC controller 16 detects the direction of the tilt, and then starts the electric telescopic rod 48 in that direction and the relative direction, so that the electric telescopic rod 48 continues to move downward, thereby squeezing the airbag 45 to further fix the black box 33. Since the ship is tilted in the opposite direction due to the force in this direction, the black box 33 at these two positions needs to be further tightened.

[0050] At the same time, by starting the two-way exhaust pump 5, the refrigerated air in the refrigeration shell 311 is extracted through the two-way exhaust pump 5, and then the moisture in the air is adsorbed by the desiccant column 9, and then discharged into the storage frame 1 to prevent the black box 33 from being overheated and damaged. When the cold air enters, the hot air will be discharged through the air outlet pipe 13. The PLC controller 16 controls the two-way exhaust pump 5 to reverse at regular intervals, thereby extracting the hot air in the storage frame 1 and then discharging it into the desiccant column 9 to dry the desiccant column 9 for recycling.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
