Description

Technical Field

[0001] This invention relates to the field of underwater electronic equipment technology, and in particular to a tensioning and heat dissipation structure inside an underwater electronic cabin. Background Technology

[0002] Because underwater electronic equipment uses a pressure-resistant sealed structure, the heat generated by the internal heating elements is difficult to dissipate, which can easily lead to an increase in the temperature inside the cabin, affecting the stability and lifespan of the components, and even causing malfunctions.

[0003] Currently, there are two main heat dissipation methods: one is to install heat dissipation fins inside the cabin and use fans for forced heat dissipation, but there are gaps between the heat dissipation fins and the cabin wall, and the fans increase energy consumption and the risk of failure, resulting in low heat dissipation efficiency; the other is to use a wall-mounted heat dissipation structure, which is attached to the cabin wall, but has poor vibration resistance and is easily loosened or detached due to equipment vibration or underwater disturbance, resulting in unstable heat dissipation effect.

[0004] Therefore, there is an urgent need for an underwater electronic compartment tensioning and heat dissipation structure that is simple in structure, stable in tension, and efficient in heat dissipation. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] like Figure 1-10 As shown, an embodiment of the present invention provides an underwater electronic compartment internal expansion and heat dissipation structure, including an electronic compartment body 1000 and an actuator 2000. The electronic compartment body 1000 includes a main compartment body 1100, which extends along a first direction and has a through-hole cavity that also extends along the first direction for housing the actuator 2000 and electronic equipment. A cylindrical swing rod 1300 extending along the first direction is provided inside the cavity. Removable and washable sealing end caps 1200 are provided at both ends of the cavity. The main compartment body 1100 and the sealing end caps 1200 are connected to form a watertight structure.

[0025] Combination Figure 4 , Figure 5 , Figure 6 and Figure 7The actuator 2000 is used to place electronic equipment and contact the inner wall of the accommodating cavity for heat dissipation. The actuator 2000 is disposed inside the accommodating cavity, and one end of it is connected to a sealing end cap 1200, which can drive the actuator 2000 to rotate. The actuator 2000 includes a heat dissipation mechanism 2100 and a tensioning mechanism 2200. The heat dissipation mechanism 2100 is used to fix the electronic equipment in the accommodating cavity and dissipate heat. The heat dissipation mechanism 2100 includes a mounting base 2110, which serves as the subsequent mounting base. Heat-conducting mounting plates 2120 are symmetrically hinged on both sides above it. The heat dissipation mechanism 2100 is disposed at both ends of the mounting base 2110. The tensioning mechanism 2200 includes an elastic device 2210, which is fixedly connected to the mounting base 2110. The elastic device 2210 is provided with a connecting push rod 2220 hinged to the end of the heat-conducting mounting base 2120 near the end of the heat-conducting mounting base 2120. The elastic device 2210 is provided with a crank connecting rod device 2230 away from the end of the heat-conducting mounting base 2120. One end of the crank connecting rod device 2230 extends into the interior of the elastic device 2210 and can drive the elastic device 2210 to extend and retract. The other end of the crank connecting rod device 2230 is provided with a limit block 2300, which is connected to the mounting base 2110. During the rotation of the actuator 2000 driven by one of the sealing end caps 1200, the other end of the crank connecting rod device 2230 contacts the rocker arm 1300 and the limiting block 2300. The rocker arm 1300 and the limiting block 2300 are limited by the crank connecting rod device 2230, causing them to move in a second direction perpendicular to the first direction. This causes the elastic device 2210 to extend and retract, thereby causing the connecting push rod 2220 to push the heat-conducting mounting petal 2120 to rotate around the hinge point with the mounting bottom petal 2110, so that it contacts or moves away from the inner wall of the accommodating cavity.

[0026] like Figure 2 As shown, the main compartment 1100 is used to install electronic equipment and dissipate heat. The main compartment 1100 is generally hollow cylindrical, and its end is provided with a connection hole 1400 around the accommodating cavity to facilitate connection with the sealing end cap 1200. The rocker arm 1300 is used to cooperate with the tensioning mechanism 2200 to trigger and limit the tensioning action. It is generally cylindrical to facilitate cooperation with the crank connecting rod device 2230. The rocker arm 1300 is detachably fixed in the accommodating cavity.

[0027] like Figure 3As shown, the sealing end cap 1200 is used to achieve end sealing of the electronic compartment 1000, and cooperates with the main compartment 1100 to form a watertight cavity. The sealing end cap 1200 includes a connecting section and a sealing section that are connected to each other. Both the connecting section and the sealing section are cylindrical. The outer diameter of the connecting section is the same as that of the main compartment 1100 to maintain the overall streamlined shape. The connecting section is also provided with a through hole corresponding to the connecting hole 1400. The main compartment 1100 and the sealing end cap 1200 are connected to each other by fastening screws passing through the through hole and the connecting hole 1400 to form an integral sealed cavity, which is suitable for underwater sealing environment. The outer diameter of the sealing section is the same as the inner diameter of the accommodating cavity. In order to enhance the sealing performance between the sealing end cap 1200 and the main compartment 1100, the sealing section is provided with multiple annular grooves at intervals around its circumference, and sealing rings are arranged in the annular grooves.

[0028] like Figure 7 As shown, the mounting base 2110 has inwardly recessed fixing grooves at both ends along the first direction to facilitate fixing the elastic device 2210. The limiting block 2300 is arranged below the fixing groove. The mounting base 2110 is arc-shaped towards the main body 1100, and its other side has an inwardly recessed first mounting cavity 2111 for installing electronic equipment. The connecting ends of the mounting base 2110 and the heat-conducting mounting petal 2120 are both provided with collars 2112. The first mounting cavity 2111 and the collars 2112 on the heat-conducting mounting petal 2120 are staggered. The mounting base 2110 and the heat-conducting mounting petal 2120 form a stable hinge structure through the mounting guide rod 2130 passing through the collar 2112, ensuring that the heat-conducting mounting petal 2120 can open and close flexibly. One end of the mounting guide rod 2130 is connected to the sealing section of the sealing end cover 1200. A pair of thermally conductive mounting flaps 2120 are symmetrically mounted on the mounting base flap 2110.

[0029] like Figure 8As shown, the heat-conducting mounting flap 2120 is made of heat-conducting material. The heat-conducting mounting flap 2120 is arc-shaped towards the main body 1100. The end of the arc-shaped side of the other end is provided with an inwardly recessed connecting groove 2121. The connecting groove 2121 is provided with a connecting hole extending in the first direction, which connects to the nearest end. A connecting pin 2122 is provided inside the connecting hole. The two ends of the connecting pin 2122 extend towards the connecting groove 2121 and the end of the heat-conducting mounting flap 2120, respectively. The end of the pin extending towards the end of the heat-conducting mounting flap 2120 is used to connect to the connecting push rod 2220. A detachable fixing rod 2123 is connected to the connecting end of the connecting groove 2121. The fixing rod 2123 is installed on the heat-conducting mounting flap 2120 by mounting screws. The heat-conducting mounting flap 2120 is provided with two corresponding mounting screw holes for fixed installation and fixing of the connecting pin 2122. On the other side of the heat-conducting mounting flap 2120, there is a second mounting cavity 2124 for mounting electronic equipment. The second mounting cavity 2124 is provided with an arc-shaped closed groove 2125 on the side away from the mounting guide rod 2130. The arc-shaped closed groove 2125 extends along the first direction.

[0030] Furthermore, when the heat-conducting mounting flap 2120 needs to be fully opened to install the heating element, the mounting screws of the fixing rod 2123 can be unscrewed, the connecting pin 2122 and the fixing rod 2123 can be retracted, and after adjustment, the mounting screws can be tightened again to fix them, thereby separating the heat-conducting mounting flap 2120 from the tensioning mechanism 2200. During installation, the connecting pin 2122 is inserted into the corresponding connector of the connecting push rod 2220 to connect the heat-conducting mounting flap 2120 to the tensioning mechanism 2200, ensuring that the tensioning force can be effectively transmitted to the heat-conducting mounting flap 2120.

[0031] like Figure 4 , Figure 5 and Figure 7 As shown, an installation rod 2140 is provided between a pair of arc-shaped closed grooves 2125, which extends along the first direction. The installation rod 2140 is arranged above the installation bottom flap 2110, and one end of it is connected to the sealing section of one of the end caps 1200. When the pair of heat-conducting installation flaps 2120 are closed, the pair of arc-shaped closed grooves 2125 form a placement cavity for accommodating the installation rod 2140. The inner wall of the placement cavity abuts against the installation rod 2140. The pair of heat-conducting installation flaps 2120 and the installation bottom flap 2110 close to form a cylinder with an outer diameter smaller than the inner diameter of the placement cavity, so as to be installed inside the electronic cabin 1000.

[0032] Furthermore, an inclined opening groove is provided at the corresponding position on the outer side of the arc-shaped closed groove 2125 to facilitate manual opening and closing of the pair of heat-conducting mounting flaps 2120.

[0033] like Figure 1 , Figure 5 and Figure 7As shown, one end of the mounting rod 2140 and the mounting guide rod 2130 are fixedly connected to the sealing end cover 1200, and the other end of the two are connected to the connecting ring 2150. After the entire device is connected, a stable structure is formed between the mounting rod 2140, the mounting guide rod 2130, the connecting ring 2150 and the sealing end cover, which effectively improves the rigidity of the overall structure and avoids structural deformation after assembly.

[0034] Furthermore, a gap is provided between the connecting ring 2150 and the heat-conducting mounting flap 2120 and the mounting bottom flap 2110 to facilitate the installation of the tensioning mechanism 2200.

[0035] like Figure 9 and Figure 10 As shown, the tensioning mechanism 2200 is installed on both sides of the heat dissipation mechanism 2100. It includes an elastic device 2210, a connecting push rod 2220, and a crank-connecting rod device 2230. The elastic device 2210 includes a mounting base 2211, which is fixedly installed in a fixing groove. A through mounting hole for mounting the crank-connecting rod device 2230 is provided at its center. An elastic element 2212 is provided directly above the mounting hole. The elastic element 2212 is a spring. The two ends of the spring are respectively connected to a base 2213 and a connecting movable pin 2215. One end of the base 2213 is connected to the spring. One end is fixedly connected, and the other end faces the mounting hole. The base 2213 is provided with a through hole corresponding to the mounting hole. The bottom is provided with a groove 2214 around the through hole. One end of the connecting movable pin 2215 is connected to the other end of the spring. The other end is connected to a push rod connecting seat 2216. The push rod connecting seat 2216 is hinged to the connecting push rod 2220 through the push rod connecting pin 2217. The other end of the connecting movable pin 2215 is also provided with a countersunk hole 2218. One end of the crank connecting rod device 2230 passes through the mounting hole, the through hole and the spring in sequence and extends into the countersunk hole 2218.

[0036] like Figure 9 and Figure 10 As shown, the connecting push rod 2220 is a rod-shaped structure with connectors at both ends. One connector is hinged to the push rod connecting seat 2216 via the push rod connecting pin 2217, and the other connector extends from the connecting pin 2122 to the end of the heat-conducting mounting petal 2120. A pair of connecting push rods 2220 are respectively connected to the heat-conducting mounting petal 2120, and the opening and closing of the heat-conducting mounting petal 2120 is controlled by the push of the elastic device 2210.

[0037] like Figure 9 and Figure 10As shown, the crank-connecting rod device 2230 includes a connecting rod 2231. One end of the connecting rod 2231 is provided with a screw hole 2232. This end passes through the mounting hole, the through hole, and the spring, and extends into the countersunk hole 2218. It is connected to the push rod connecting seat 2216 as a whole by a screw 2233. This end is also provided with a boss 2234 that cooperates with the groove 2214. The groove 2214 and the boss 2234 cooperate with each other to achieve the center positioning of the elastic element 2212. The other end of the connecting rod 2231 is hinged to a crank 2236 through a support pin 2235. The crank 2236 is provided with an arc-shaped groove 2237 facing the limiting block 2300. The arc-shaped groove 2237 cooperates with the limiting block 2300 and the rocker arm 1300 to realize the movement of the connecting rod 2231 in the second direction.

[0038] Furthermore, the pair of cranks 2236 at both ends of the heat dissipation mechanism 2100 are connected to each other by a connecting rod 2400 to ensure that the two tensioning mechanisms 2200 operate in a consistent manner and avoid uneven tension on one side.

[0039] Tensioning process: During overall installation, first install the sealing end cap 1200 at one end of the main body 1100. After the heat dissipation mechanism 2100 and tensioning mechanism 2200 are assembled, connect both ends to the sealing end cap 1200 and connecting ring 2150 at the other end, and then install them into the main body 1100. During the installation process, the arc-shaped slot 2237 of the crank 2236 of the tensioning mechanism 2200 is inserted into the rocker arm 1300 in the receiving cavity. After the end faces of the sealing end cap 1200 and the actuator 2000 are in contact with the end face of the electronic body 1000, rotate the sealing end cap 1200 and the actuator 2000 at the other end; during the rotation, the crank 2236... 236 is restricted in its movement by the swing rod 1300 and the limiting block 2300, which in turn pushes the connecting movable pin 2215 to move upward in the second direction. After the connecting movable pin 2215 moves upward, it compresses the elastic element 2212 sleeved on its axis. The compressed elastic element 2212 generates an elastic restoring force, pushing the connecting movable pin 2215 and the push rod connecting seat 2216 upward. When the push rod connecting seat 2216 moves upward, it pushes the two connecting push rods 2220 to open to a larger angle, which in turn pushes the pair of heat-conducting mounting petals 2120 to open to a larger angle simultaneously, until the heat-conducting mounting petals 2120 are tightly pressed against the inner wall of the accommodating cavity, completing the tensioning action. The outer arc diameter of the heat-conducting mounting petals 2120 is consistent with the inner diameter of the accommodating cavity. The compressed elastic element 2212 always maintains a stable tension force, so that the heat-conducting mounting flap 2120 and the inner wall of the accommodating cavity always remain in a tight fit, avoiding loosening of the fit due to vibration and pressure changes in the underwater environment, and ensuring the reliability of heat transfer.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
