The control module 32 is installed in the accommodation space enclosed by the installation wall 311, the side walls 312 and the cover plate 313, and at least three of the cover plate 313 and the four side walls 312 are detachably connected, so that the side-open connection between the cover plate 313 and the side walls 312 is realized, the accommodation space can be covered or opened by the cover plate 313, and the control module 32 can be conveniently installed and overhauled by an operator. The cover plate 313 may be snap-fit with the four side walls 312 or hinged with one of the side walls 312 to provide a detachable connection with at least three of the four side walls 312.
In one embodiment, the case 31 is made of a 2 mm stainless steel plate, and the surface is plastic-sprayed, and the protection grade is IP22. In particular, the plastic spraying is a surface treatment method for spraying plastic powder on parts, which is also called electrostatic powder spraying coating, and the process is more firm and durable compared with the common spray painting surface treatment, and is suitable for occasions with high pollution and high saline-alkali corrosion.
In one embodiment, sealing beads are filled between the cover plate 313 and the four side walls 312 to ensure good tightness of the receiving space. Specifically, an annular first mounting groove is formed in the end face, facing the accommodating space, of the cover plate 313, a second mounting groove corresponding to the first mounting groove is formed in the end face, facing the cover plate 313, of the four side walls 312, sealing pressing strips are mounted in the first mounting groove or the second mounting groove, and when the cover plate 313 covers the accommodating space, the sealing pressing strips are simultaneously contained in the first mounting groove and the second mounting groove, so that good sealing of the accommodating space is achieved, and the control module 32 in the accommodating space is placed to be damaged due to damp.
The control module 32 is installed in the case 31 in a vertical installation manner and faces the cover 313 of the case 31, so as to facilitate installation and debugging.
The control module 32 includes a control board, a wiring terminal and a power interface, which are disposed in the lower half of the control board.
In one embodiment, the power interface adopts a dual-power design, and the main power supply provides power during normal operation, and after the main power supply is disconnected, the power interface can be switched to a backup power supply to maintain operation, so that the sailing stability of the ship is ensured.
The damping device comprises a first damping assembly 4 arranged between the tank 31 and the vessel wall 13 and a second damping assembly 5 arranged between the control panel and the tank 31.
The first vibration damping assembly 4 comprises at least 4 vibration damping springs, one ends of the four vibration damping springs are connected with the mounting wall 311 of the box body 31, the other ends of the four vibration damping springs are connected with the ship wall 13, and the plurality of vibration damping springs are arranged at equal intervals so as to reduce the influence of the vibration of the ship body 1 on the control module 32 in the box body 31. In one embodiment, 4 damper springs are disposed near the 4 corners of the mounting wall 311, respectively.
The second vibration damping assembly 5 includes at least 4 vibration damping springs, one ends of the four vibration damping springs are connected with the mounting wall 311 of the tank body 31, the other ends of the four vibration damping springs are connected with the control board, and the plurality of vibration damping springs are arranged at equal intervals so as to reduce the influence of the vibration of the hull 1 on the control module 32 in the tank body 31. In one embodiment, 4 damper springs are disposed near the 4 corners of the mounting wall 311, respectively.
Because the hull 1 vibrates greatly or the control box 3 is installed unstably, in the ship navigation process, the box 31 can drop from the ship wall 13 to generate impact, and the impact can cause the damage or drop of elements on the control panel to the great extent, so that the ship is out of control, and in order to solve the problem, the control box 3 further comprises a third vibration reduction assembly 6, and when the box 31 drops, the third vibration reduction assembly 6 is used for buffering the impact force generated by the dropping of the box 31.
Specifically, the third vibration damping assembly 6 includes a detecting unit 61, a judging unit, a control unit and a buffer unit 62, where the detecting unit 61 is configured to detect spatial position change data of the case 31 and generate detection information, the judging unit receives the detection information and judges whether the case 31 falls, and when the judging unit judges that the case 31 falls, the judging unit sends a trigger signal to the control unit, and the control unit controls the buffer unit 62 to switch from the first state to the second state, and the volume of the buffer unit 62 in the second state is larger than the volume in the first state.
In one embodiment, the cushioning unit 62 is configured as an inflatable and deflatable airbag that is compressed to have a small volume when the cushioning unit 62 is in the first state, and has a large volume of air inside when the cushioning unit 62 is in the second state, so that it has the function of cushioning an external force. Specifically, the buffer unit 62 is detachably connected to the cover 313, and when the buffer unit 62 is in the second state, it at least partially covers 5 sides of the case 31.
In an embodiment, the detecting unit 61 is configured as a distance sensor, the distance sensor is used for detecting an actual distance between the box 31 and the bottom plate 11 or the top plate of the ship as detection information, the judging unit receives the actual distance and compares the actual distance with a preset distance, when the actual distance is greater than the preset distance, the judging unit judges that the box 31 falls, and further the judging unit transmits a trigger signal to the control unit, the control unit receives the trigger signal, and the buffer unit 62 is controlled to switch from the first state to the second state. Since a large amount of air exists in the buffer unit 62 in the second state and at least partially covers 5 surfaces of the box 31, the buffer unit 62 can buffer the impact force formed between the box 31 and the hull 1 when the box 31 falls down, so that the control panel in the box 31 can be protected from damage.
A false positive may occur if the preset distance is too small, and the buffer unit 62 does not have enough time to switch from the first state to the second state, and in one embodiment, the preset distance is set to 5 cm to 10 cm, preferably 6 cm to 8 cm.
In other embodiments, other types of sensors may be used, and only based on the detection data from the sensors may be used to determine whether an uncontrolled change occurs in the control position of the housing 31.
When the box 31 falls to the bottom plate 11 of the ship, it is necessary to check whether the control panel is damaged in time and install the box 31 to the ship wall 13, and since the ship is noisy during sailing, the box 31 may not be easily found, and there may be damage to the control panel and failure to repair in time to make the ship run away, or the box 31 may be damaged due to the vibration of the bottom plate 11 or the risk of water accumulation. To solve this problem, the control system of a ship propelled by semi-submerged paddles further comprises a prompting device, wherein the prompting device is used for receiving the trigger signal and sending out a signal which can be perceived by human beings, for example: sound, light, smell, etc. to draw the attention of the operator. The prompting device comprises a prompter and a switch, and when the prompter is triggered, a user needs to operate the switch to close the prompter. In one embodiment, the indicator is a buzzer or a warning light.
