A hull central control heat dissipation structure and an unmanned ship

Abstract

The application discloses a ship body central control heat dissipation structure and an unmanned ship, and relates to the technical field of unmanned ship manufacturing. The ship body central control heat dissipation structure comprises a ship body, a central control bin, a window penetrating through the bottom of the central control bin to the bottom of the ship body, a heat dissipation structure arranged in the window and formed as part of the bottom of the ship body, a box shell made of metal, the box shell being arranged in the central control bin and fixed to the other side of the heat dissipation structure, and a central control device arranged in the box shell and having a heat generating module fixed to the bottom of the box shell. Most of the heat generated by the heat generating module of the central control device is conducted to the box shell, and the heat can be better dissipated to the environment outside the box shell through the box shell. Since the box shell is in abutment with the heat dissipation structure, most of the heat conducted to the box shell is conducted to the heat dissipation structure and then to the water body in which the ship body sails. In this way, the heat on the metal plate can be well dissipated by using the flowing water body during high-speed sailing of the ship body.

Description

Technical Field

[0001] This application relates to the field of unmanned ship manufacturing technology, and in particular to a hull central control heat dissipation structure and an unmanned ship. Background Technology

[0002] Underwater topographic surveying is a specific type of engineering surveying, primarily used to measure the horizontal position and elevation of rivers, lakes, reservoirs, harbors, and nearshore points to create underwater topographic maps. In recent years, with the rapid development of water conservancy and the increasing emphasis on water resources, the geographical information of rivers and reservoirs has received increasing attention. Among these, acquiring topographic data of rivers and reservoirs has become a focal point. Underwater topographic surveying mainly uses acoustic and optical equipment for data acquisition. With technological advancements, unmanned surface vessels (USVs) equipped with surveying equipment are commonly used to replace manual surveying. In current technology, USVs typically carry ADCP (Advanced Digital Conversion Technology) and dual-frequency depth sounders to measure river flow velocity, discharge, and water depth. To obtain relatively accurate measurement data, high requirements are placed on the protection of the vessel hull.

[0003] Commonly used unmanned surface vessels (USVs) are usually equipped with a standard moon pool and protective cover before leaving the factory. In some cases, they are also equipped with corresponding equipment mounting brackets according to customer needs (to meet the actual measurement needs of users, the mounting brackets are generally multi-purpose brackets). Due to the universality of the mounting brackets, the brackets themselves have many pre-reserved fixing and cable outlet holes, which greatly reduces the protection level of the moon pool part.

[0004] The central control unit of an unmanned surface vessel (USV) is its core control component. It requires a high level of protection and also has high heat dissipation requirements. Insufficient heat dissipation can lead to the central control unit crashing, remote control failure, and, more importantly, cause great trouble in emergency situations such as emergency braking and return to port during the test of the measurement vessel. It poses significant risks and potential hazards, and the product will lose its market competitiveness. Utility Model Content

[0025] Reference Figures 1 to 3 This application provides an unmanned vessel, which includes a hull-mounted central heat dissipation structure 170.

[0026] In some embodiments, the bottom of the hull 100 of the unmanned vessel is provided with a thruster 110, and the top of the hull 100 is provided with a receiving and control antenna 120, a cabin, a moon pool 140 and a positioning and directional antenna 150 in sequence from the rear to the front. The cabin is provided with an openable cabin cover 130.

[0027] Unmanned surface vessel (USV) surveying primarily relies on mounted surveying equipment for measurement operations. This equipment mainly comprises the hull 100, external equipment, and a central control unit 200, all secured with mounting screws. Typically, the central control equipment is installed inside the hull. Furthermore, to ensure the overall balance of the hull 100, it is generally weight-matched with the propeller 110 and battery pack to guarantee the hull 100's balance in the water. In this embodiment, as shown... Figure 2The example shown is that the central control unit is installed at the rear of the ship. Before the assembly is completed, the internal cables of the ship 100 must be connected one by one to the corresponding external interfaces of the central control unit.

[0028] In the embodiments of this application, such as Figure 4 and Figure 5 As shown, the hull central control heat dissipation structure 170 includes a hull 100, a heat dissipation structure 170, a housing, and central control equipment. The hull 100 is provided with a central control compartment 160, and a window extending through to the bottom of the hull 100 is opened at the bottom of the central control compartment 160. The heat dissipation structure 170 is located at the window and is formed as part of the bottom of the hull 100. One side of the heat dissipation structure 170 is exposed outside the bottom of the hull 100. The housing is made of metal, can be opened and is in a sealed state, and is located inside the central control compartment 160 and fixed to the other side of the heat dissipation structure 170. The central control equipment is located inside the housing, and the heating module 210 of the central control equipment is fixed to the bottom of the housing.

[0029] During use, since the heating module 210 is in contact with the housing, most of the heat generated by the heating module 210 of the central control equipment is conducted to the housing. The metal housing has a fast heat conduction efficiency, and the heat can be dissipated to the environment outside the housing more quickly. Since the housing is in contact with the heat dissipation structure 170, most of the heat conducted to the housing is conducted to the heat dissipation structure 170, and then conducted to the water in which the ship 100 is sailing through the heat dissipation structure 170, so that the heat can be received by the water, which effectively improves the heat dissipation efficiency of the central control equipment.

[0030] There are generally two ways to dissipate heat from the central control equipment of existing unmanned vessels. The first is through natural heat dissipation, where the central control equipment dissipates heat into the cabin. The second is to add water cooling equipment to remove the heat from the central control equipment through small water pumps, heat dissipation metal pipes, etc. This method has some effect, but the cost is high. After installing the equipment, the power consumption of the battery is greatly increased, which shortens the actual endurance of the survey vessel. Therefore, it is not the best method.

[0031] The solution in this application relies on the heat dissipation structure 170 at the bottom of the hull 100 to conduct the heat generated by the central control equipment to the water in which the hull 100 is sailing.

[0032] In some embodiments, such as Figure 4 and Figure 5 As shown, the heat dissipation structure 170 includes a first metal plate 171 and a second metal plate 173. The first metal plate 171 is sealed and fixed to the bottom of the central control compartment 160 to block the window, and the second metal plate 173 is sealed and fixed to the outer side of the bottom of the hull 100 to block the window. A portion of the second metal plate 173 extends to abut against the first metal plate 171.

[0033] Both the first metal plate 171 and the second metal plate 173 are sealed to the hull 100 to prevent water from seeping in from the connection. The second metal plate 173 extends to abut against the first metal plate 171, which can better conduct heat. The metal plate has a faster heat transfer efficiency.

[0034] In this embodiment of the application, the shell, the first metal plate 171 and the second metal plate 173 can be made of aluminum or copper.

[0035] In some embodiments, a first sealing groove 176 is provided on the part of the first metal plate 171 that is attached to the bottom of the central control compartment 160, and a sealing element is placed in the first sealing groove 176.

[0036] Specifically, the first metal plate 171 is fixedly connected to the bottom of the central control compartment 160 by bolts. Specifically, the first metal plate 171 is provided with through holes, and the bottom of the central control compartment 160 is provided with screw holes. After the bolts pass through the through holes, they are connected to the screw holes. The sealing element provided in the first sealing groove 176 is squeezed and deformed to fill the gap between the first sealing groove 176 and the bottom of the central control compartment 160, effectively improving the waterproof sealing effect.

[0037] The portion of the second metal plate 173 that is in contact with the bottom of the hull 100 is provided with a second sealing groove 175, and a sealing element is placed in the second sealing groove 175.

[0038] Specifically, the second metal plate 173 is fixedly connected to the bottom of the hull 100 by bolts. Specifically, the second metal plate 173 is provided with through holes, and the bottom of the hull 100 is provided with screw holes. After the bolts pass through the through holes, they are connected to the screw holes. The sealing element provided in the second sealing groove 175 is squeezed and deformed to fill the gap between the second sealing groove 175 and the bottom of the hull 100, effectively improving the waterproof sealing effect.

[0039] In some other embodiments, both the first sealing groove 176 and the second sealing groove 175 are annular, and the sealing element is a rubber sealing ring.

[0040] In some examples, such as Figure 5 As shown, the portion of the second metal plate 173 facing the window is provided with a protruding part 172, which abuts against the first metal plate 171. This direct contact effectively improves the heat conduction efficiency from the first metal plate 171 to the second metal plate 173.

[0041] In some other embodiments, the portion of the second metal plate 173 that contacts the protrusion 172 is provided with a storage groove 174, which stores thermal grease.

[0042] In some other embodiments, the portion of the protrusion 172 that contacts the second metal plate 173 may be provided with a storage groove 174, which stores thermal grease.

[0043] By setting up a storage slot 174 and placing thermal grease in the storage slot 174, the heat conduction efficiency from the first metal plate 171 to the second metal plate 173 can be greatly improved, effectively enhancing the heat dissipation effect.

[0044] In some specific embodiments, thermal grease can be directly applied between the heating module 210 and the bottom of the housing, or thermal grease can be added to improve the heat conduction effect.

[0045] In some specific embodiments, thermal grease can be directly applied between the housing and the heat dissipation structure 170, or additional thermal grease can be added to improve the heat conduction effect.

[0046] In the embodiments shown in this application, the heating module 210 is very close to the bottom of the housing, and the gap space is filled with thermal grease.

[0047] To ensure the protection level of the enclosure (the sealing performance of the metal enclosure can be guaranteed at room temperature, but under high and low temperature impacts, negative pressure is generated inside the enclosure, which greatly increases the risk to the protection level), a waterproof and breathable valve is added to the enclosure (the breathable valve keeps the air pressure inside the enclosure balanced with the external air pressure), thereby improving the overall protection capability of the machine.

[0048] In some specific embodiments, such as Figures 6 to 8 As shown, the housing includes a first housing 230 and a second housing 220. The first housing 230 and the second housing 220 are fitted together. The fitted connection allows for quick positioning, making disassembly and assembly convenient, and the fitted connection provides a better sealing effect.

[0049] Connecting ears 222 are provided on both sides of the outer side of the second housing 220. The connecting ears 222 are provided with through holes. The first metal plate 171 is provided with screw holes corresponding to the through holes. The second housing 220 is locked to the second metal plate 173 by fastening screws 223.

[0050] In some embodiments, such as Figure 7 As shown, the first housing 230 has a slot 231 on one open edge, and the second housing 220 has a protrusion 221 on one open edge. The protrusion 221 fits into the slot 231. A sealing ring 240 is provided in the slot 231. The sealing effect is improved by the fitting connection between the protrusion 221 and the slot 231. The sealing ring 240 is added in the slot 231 to fill the gap and further improve the waterproof sealing effect.

[0051] In this embodiment, the heat generated by the heating module 210 in the central control device during operation is conducted to the housing. In actual use, the housing is fixed to the heat dissipation structure 170 by fixing screws. The working principle of the heat dissipation structure 170 is to replace the hull with a metal base plate with better heat dissipation after opening a window at the bottom of the hull, and at the same time, it is sealed with the bottom of the hull to become part of the bottom of the hull. In this way, the heat on the metal plate can be effectively dissipated by the flowing water during the high-speed movement of the hull 100, and at the same time, the internal protection of the hull 100 can be protected. The housing is fixed to the hull 100 on the metal plate by fixing screws (with thermal grease added in the middle gap). The heat of the central control device can be quickly conducted to the metal plate through the housing. At this time, the heat generated by the central control device is effectively conducted to the water by relying on the metal plate. This method protects the equipment well, and at the same time, there is no need to worry about the protection of the central control device affecting the stability of the hull 100.

[0052] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
