Description

Technical Field

[0001] This invention belongs to the field of engine room temperature control technology, specifically referring to a temperature control device for the engine room of a hydrographic survey vessel. Background Technology

[0002] When unmanned survey vessels perform long-term, uninterrupted continuous operations, their cabins are densely packed with various high-density electronic devices, including but not limited to sophisticated flight control computers, large-capacity power supplies, and high-speed communication modules. These core components continuously release a large amount of heat under long-term high-load operation, requiring ventilation of the unmanned survey vessel's cabin to control the cabin temperature.

[0003] The existing temperature control equipment in the engine room of hydrological survey vessels has the following problems:

[0004] The existing temperature control equipment in the engine room of hydrological survey vessels does not have the ability to clean the parts of the hull that are submerged in water, which affects the smoothness of the hull and interferes with the transmission and reception of sound waves, resulting in noise and distortion in the survey data and reducing the efficiency of water area surveys. In addition, when the traditional temperature control equipment in the engine room of hydrological survey vessels is sailing at high speed, the huge hydrodynamic force will force the bow to rise and the stern to sink, forming unfavorable postures such as "pitch" or "dolphin movement", which will affect the stability of the survey vessel and thus cannot guarantee the reliability of the survey mission.

[0005] Therefore, it cannot meet the current demand for temperature control equipment in the engine room of hydrological survey vessels. Summary of the Invention

[0006] In response to the above situation and to overcome the shortcomings of the existing technology, this solution provides a temperature control device for the engine room of a hydrographic survey vessel that can introduce airflow after ventilation into the water, use the formed bubbles to clean the bottom of the hull when it is at low speed or hovering, and increase the buoyancy of the stern of the hull when the hull is sailing at high speed, thus maintaining the navigation attitude of the survey vessel.

[0007] The technical solution adopted in this proposal is as follows: This proposal provides a temperature control device for the engine room of a hydrological survey vessel, including an unmanned survey vessel, a survey sensor, a photovoltaic energy storage module, a bubble-type ventilation mechanism, and a slip-tail type buoyancy enhancement mechanism. The survey sensor is located on the unmanned survey vessel, and the photovoltaic energy storage module is located on one side of the survey sensor. The bubble-type ventilation mechanism includes a temperature control component and a bubble component. The temperature control component is located at the stern of the unmanned survey vessel, and the bubble component is located at the bottom of the unmanned survey vessel. The slip-tail type buoyancy enhancement mechanism includes a guide component, a reset component, and a buoy assembly. The guide component is located on the bottom wall of the unmanned survey vessel, the reset component is located on the side wall of the unmanned survey vessel, and the buoy assembly is located on the upper wall of the bubble component.

[0008] As a further preferred embodiment of the present invention, the temperature control component includes a ventilation duct, a ventilation fan, a ventilation valve, a ventilation pipe, and a one-way air intake valve. The ventilation duct is located at the stern of the unmanned survey vessel and is connected to the interior of the engine room of the unmanned survey vessel. The ventilation fan is located inside the ventilation duct. The ventilation valve is connected to the upper wall of the ventilation duct. The ventilation pipe is connected to the end of the ventilation valve away from the ventilation duct. The one-way air intake valve is located on the unmanned survey vessel and is connected to the interior of the engine room of the unmanned survey vessel. The bubble assembly includes an annular block, a bubble box, a flow-facing arc plate, and a one-way exhaust valve. The annular block is located below the bottom of the unmanned survey vessel. The bubble box is located on the inner wall of the annular block. The flow-facing arc plate is located on the side of the annular block near the end of the unmanned survey vessel. Multiple sets of the one-way exhaust valves are connected to the upper wall of the bubble box.

[0009] In use, the ventilation fan draws hot air from the engine room of the unmanned survey vessel into the ventilation duct. The ventilation duct then delivers the hot air to the bubble chamber through the ventilation pipe. The bubble chamber then discharges the gas into the bottom of the unmanned survey vessel through a one-way exhaust valve. The gas discharged into the water forms bubbles that impact the bottom of the unmanned survey vessel. The impact force of the bubbles can be used to clean dirt adhering to the bottom of the hull when the unmanned survey vessel is sailing at low speed or hovering.

[0010] Preferably, the guiding assembly includes a guide rail and a sliding frame. The guide rail is symmetrically arranged on the bottom wall of the unmanned survey vessel, and the sliding frame is slidably arranged on the bottom wall of the guide rail, with the side of the sliding frame away from the guide rail connected to an annular block. The reset assembly includes a positioning block, a reset spring, and a reset frame. The positioning blocks are symmetrically arranged on both sides of the end of the unmanned survey vessel. The reset spring is located on the side wall of the positioning block and is in a retracted state. The reset frame is located between the side of the reset spring away from the positioning block and the sliding frame. The ball-pressing assembly includes a groove, a hollow magnetic ball, and a float. The device includes a force spring, a pressure ball magnetic strip, and a buoyancy airbag. Multiple sets of grooves are located on the outside of some one-way exhaust valves, with the grooves having an open top. The hollow magnetic ball is located above the groove. The buoyancy spring is located between the groove on the outside of the one-way exhaust valve and the hollow magnetic ball, and the buoyancy spring is in a contracted state. Some one-way exhaust valves are in a closed cut-off state. Multiple sets of pressure ball magnetic strips are located at the end of the guide rail away from the bubble box, and the pressure ball magnetic strips and the hollow magnetic ball are set with the same pole. The buoyancy airbag is located on the side of the annular block away from the upstream arc plate, and the buoyancy airbag passes through the annular block and communicates with the bubble box.

[0011] In use, when the unmanned survey vessel is sailing at high speed, the impact force of the water flow uses the elastic deformation of the return spring to push the upstream arc plate. The upstream arc plate pushes the sliding frame along the bottom wall of the guide rail through the annular block. The sliding frame moves the bubble box to the bottom of the pressure ball magnetic strip. The pressure ball magnetic strip is fixed to one end of the guide rail and uses repulsive force to push the hollow magnetic ball. The hollow magnetic ball uses the elastic deformation of the buoyancy spring to block part of the one-way exhaust valve. At this time, the number of one-way exhaust valves that can perform exhaust operations is reduced, and the air entering the bubble box cannot be discharged in time. The excess air enters the buoyancy airbag, and the buoyancy airbag expands and inflates, increasing the buoyancy of the stern of the unmanned survey vessel, thereby "lifting" the stern upward, counteracting its sinking trend, reducing the longitudinal tilt value of the hull, and restoring the hull of the unmanned survey vessel to stability, thereby improving the stability of the unmanned survey vessel when sailing at high speed.

[0012] Specifically, the unmanned survey vessel is equipped with a control module.

[0013] The control module is electrically connected to the ventilation fan.

[0014] The beneficial effects achieved by this solution using the above structure are as follows:

[0015] Compared with existing technologies, this solution combines a bubble-type ventilation mechanism with a slip-tail type buoyancy enhancement mechanism. Through the setting of temperature control components, bubble components, guide components, reset components, and buoyancy-pressing components, air generated by the ventilation of the unmanned survey vessel's engine room can be discharged into the water. The bubbles formed by the discharged gas in the water use a sliding bubble impact to clean the bottom of the unmanned survey vessel, thus cleaning the dirt adhering to the bottom when the unmanned survey vessel is sailing at low speed or hovering. When the unmanned survey vessel is sailing at high speed, the impact force of the water pushes the bubble box to the stern of the unmanned survey vessel. The buoyancy-pressing magnetic strip pushes the hollow magnetic ball with repulsive force, and the hollow magnetic ball blocks part of the one-way exhaust valve, reducing the amount of gas discharged from the bubble box. This causes the buoyancy airbag to inflate, increasing the buoyancy at the stern, thereby lifting the stern of the unmanned survey vessel, maintaining its sailing attitude, and improving the stability of the unmanned survey vessel at high speed.

[0030] like Figures 1-10 As shown, the proposed solution provides a temperature control device for the engine room of a hydrological survey vessel, comprising an unmanned survey vessel 1, a survey sensor 2, a photovoltaic energy storage module 3, a bubble-type ventilation mechanism 4, and a slip-tail type buoyancy enhancement mechanism 15. The survey sensor 2 is mounted on the unmanned survey vessel 1, and the photovoltaic energy storage module 3 is mounted on the unmanned survey vessel 1 to one side of the survey sensor 2.

[0031] The temperature control component 5 includes a ventilation duct 6, a ventilation fan 7, a ventilation valve 8, a ventilation pipe 9, and a one-way air intake valve 29. The ventilation duct 6 is located at the stern of the unmanned survey vessel 1 and is connected to the engine room of the unmanned survey vessel 1. The ventilation fan 7 is located inside the ventilation duct 6. The ventilation valve 8 is connected to the upper wall of the ventilation duct 6. The ventilation pipe 9 is connected to the end of the ventilation valve 8 away from the ventilation duct 6. The one-way air intake valve 29 is located on the unmanned survey vessel 1 and is connected to the engine room of the unmanned survey vessel 1. The bubble assembly 10 includes an annular block 11, a bubble box 12, a flow-facing arc plate 13, and a one-way exhaust valve 14. The annular block 11 is located below the bottom of the unmanned survey vessel 1. The bubble box 12 is located on the inner wall of the annular block 11. The flow-facing arc plate 13 is located on the side of the annular block 11 near the end of the unmanned survey vessel 1. Multiple sets of one-way exhaust valves 14 are connected to the upper wall of the bubble box 12.

[0032] The guiding assembly 16 includes a guide rail 17 and a sliding frame 18. The guide rail 17 is symmetrically arranged on the bottom wall of the unmanned survey vessel 1, and the sliding frame 18 is slidably arranged on the bottom wall of the guide rail 17. The side of the sliding frame 18 away from the guide rail 17 is connected to the annular block 11. The reset assembly 19 includes a positioning block 20, a reset spring 21, and a reset frame 22. The positioning block 20 is symmetrically arranged on both sides of the end of the unmanned survey vessel 1. The reset spring 21 is located on the side wall of the positioning block 20 and is in a retracted state. The reset frame 22 is located between the side of the reset spring 21 away from the positioning block 20 and the sliding frame 18. The ball-pressing assembly 23 includes a groove 24, a hollow magnetic ball 25, and a buoyancy spring. The spring 26, the pressure ball magnetic strip 27, and the buoyancy airbag 30 are arranged. Multiple sets of the grooves 24 are provided on the outside of some one-way exhaust valves 14. The grooves 24 are open at the top. The hollow magnetic ball 25 is located above the grooves 24. The buoyancy spring 26 is located between the grooves 24 and the hollow magnetic ball 25 on the outside of the one-way exhaust valve 14. The buoyancy spring 26 is in a contracted state. The one-way exhaust valve 14 is in a closed cut-off state. Multiple sets of the pressure ball magnetic strips 27 are located at the end of the guide rail 17 away from the bubble box 12. The pressure ball magnetic strips 27 and the hollow magnetic ball 25 are set with the same pole. The buoyancy airbag 30 is located on the side of the annular block 11 away from the flow-facing arc plate 13. The buoyancy airbag 30 passes through the annular block 11 and communicates with the bubble box 12.

[0033] The unmanned survey vessel 1 is equipped with a control module 28.

[0034] The control module 28 is electrically connected to the ventilation fan 7.

[0035] In actual use, in the initial state, a transparent limiting cover is set on the outside of the hull near the return spring 21 to limit the movement trajectory of the return spring 21 and prevent the return spring 21 from bending. The return spring 21 and the buoyancy spring 26 are both in a compressed state. The bubble box 12 is located at the bottom of the front end of the unmanned survey vessel 1. The buoyancy airbag 30 is in a deflated state. The operator puts the unmanned survey vessel 1 into the survey water area. The bubble box 12 is submerged in the water. The buoyancy spring 26 undergoes elastic deformation under the action of buoyancy, causing the hollow magnetic ball 25 to move away from the exhaust end of the one-way exhaust valve 14. At this time, the one-way exhaust valve 14 on the upper wall of the bubble box 12 is fully open. The unmanned survey vessel 1 collects water information data through the survey sensor 2. The photovoltaic energy storage module 3 converts the received solar energy into electrical energy to improve the endurance of the unmanned survey vessel 1.

[0036] When the unmanned survey vessel 1 is conducting a survey of the water area, the operation of the internal components of the engine room will generate a lot of heat. At this time, the control module 28 controls the ventilation fan 7 to start. The ventilation fan 7 rotates to draw the hot air inside the engine room of the unmanned survey vessel 1 into the ventilation duct 6. Outside air flows into the engine room through the one-way air intake valve 29 to ventilate the engine room. The ventilation duct 6 delivers the hot air to the bubble box 12 through the ventilation pipe 9. The bubble box 12 discharges the gas into the bottom of the unmanned survey vessel 1 through the one-way exhaust valve 14, thus completing the ventilation operation of the engine room of the unmanned survey vessel 1.

[0037] After the unmanned survey vessel 1 has been submerged for a long time, dirt from the water will adhere to its bottom. At this time, the gas discharged into the water forms bubbles that impact the bottom of the unmanned survey vessel 1. The impact force of the bubbles is used to clean the dirt that adheres to the bottom of the unmanned survey vessel 1 when it is sailing at low speed or hovering. Under the impact of the water flow, the bubble box 12 uses the elastic deformation of the return spring 21 to drive the sliding frame 18 to slide along the bottom wall of the guide rail 17, changing the position of the bubble box 12 on the bottom of the vessel, thereby adjusting the cleaning range of the bubbles on the bottom of the vessel.

[0038] When the unmanned survey vessel 1 is sailing at high speed, the water flow has a large impact on the surface of the hull, so there is no need to use air bubbles to clean the hull. At this time, the impact force of the water flow uses the elastic deformation of the return spring 21 to push the anti-flow arc plate 13. The anti-flow arc plate 13 pushes the sliding frame 18 along the bottom wall of the guide rail 17 through the annular block 11. The sliding frame 18 drives the bubble box 12 to move to the bottom of the pressure ball magnetic strip 27. The pressure ball magnetic strip 27 is fixed to one end of the guide rail 17 and uses repulsive force to push the hollow magnetic ball 25. The hollow magnetic ball 25 uses the elastic deformation of the buoyancy spring 26 to block part of the one-way exhaust valve 14.

[0039] With the reduction in the number of one-way exhaust valves 14 used for venting, the air entering the bubble chamber 12 cannot be expelled in time. Excess air enters the buoyancy airbag 30, causing it to inflate and increase the buoyancy at the stern of the unmanned survey vessel 1. This, in turn, "lifts" the stern upward, counteracting its sinking tendency, reducing the trim value of the hull, and restoring the stability of the unmanned survey vessel 1. This improves the stability of the unmanned survey vessel 1 at high speeds. After the speed of the unmanned survey vessel 1 decreases, the return spring 21 returns to its original position, pulling the bubble chamber 12 towards the bow. The hollow magnetic ball 25, under buoyancy, rises again away from the exhaust end of the one-way exhaust valve 14, and the buoyancy airbag 30 returns to its contracted state. The above operation can be repeated for the next use.

[0041] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this. In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
