Description

Technical Field

[0001] This invention relates to an underwater robot structure, and more particularly to an underwater robot slide-type energy compartment structure. Background Technology

[0002] The energy system provides power for the navigation and operation of underwater robots. Currently, most underwater robots use lead-acid batteries, lithium batteries, or fuel cells. For long-range underwater robots using lead-acid or lithium batteries, multiple battery packs are required, and each battery pack is large and difficult to transport. Underwater robot battery packs are divided into dry-tank type and oil-filled type. The dry-tank battery pack structure generally adds guide rails to the tank wall for support and uses end caps for fixation. The battery pack is installed as a whole outside the tank and then pushed into the dry tank. For larger underwater robots weighing over one ton, the process of installing and pushing in the battery pack requires multiple people and occupies a large space, especially during field testing, where multiple towing devices are needed. In view of the above, it is necessary to improve the structure of the energy tank of large underwater robots. Summary of the Invention

[0003] To address the aforementioned problems and to facilitate the installation of power compartments for large underwater robots while saving space and manpower, this invention provides a slide-type power compartment structure for underwater robots. This solves the problems of existing large underwater robots occupying a large area, being cumbersome to install, and having low work efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This invention provides an underwater robot slide-type energy compartment structure, including an energy compartment, individual batteries and slides. The inner wall of the energy compartment is symmetrically provided with slides on both sides, and multiple individual batteries are sequentially introduced into the energy compartment along the slides. A locking and fixing component is used to limit the multiple individual batteries at the bow of the energy compartment.

[0006] The single battery includes a battery body and a slider mechanism disposed on both sides of the battery body, the slider mechanism slidingly engaging with the slide rail.

[0007] The slider mechanism includes a slider, a rolling bearing, and an automatic locking assembly. One side of the slider is provided with a rolling bearing for cooperating with the slide rail. The automatic locking assembly is disposed on the slider and is used to automatically lock the slider in the slider mechanism located on the front side.

[0008] One end face of the slider is provided with a protrusion, the other end face is provided with a groove, and the other end of the slider is provided with a hook body contact surface perpendicular to the slider.

[0009] The two adjacent sliders are positioned by interlocking with protrusions and grooves, and the rear slider hooks the hook body of the front slider through the automatic locking assembly to achieve locking between the two adjacent sliders.

[0010] The back of the hook body's contact surface is curved, and the curved surface is used to guide the forward movement of the automatic locking assembly.

[0011] The automatic locking assembly includes a hook and a spring, wherein the rear end of the hook is hinged to the slider, and the front end of the hook is a hook-shaped part; the two ends of the spring are respectively connected to the hook and the slider, and the spring uses tension to make the hook-shaped part of the hook fit against the hook-shaped contact surface of the slider.

[0012] The slider is provided with two bearing mounting shafts, and each bearing mounting shaft is equipped with a rolling bearing through a bushing. The rolling bearing is axially limited by a retaining ring.

[0013] The locking and fixing assembly includes a crossbeam and two locking members. The crossbeam is located on the outside of the single battery cell that is finally introduced into the energy compartment, and the two ends of the crossbeam are positioned and connected to the energy compartment by the two locking members.

[0014] The inner bow of the energy compartment is provided with a limiting groove along the circumferential direction for positioning the locking component.

[0015] The locking component has a Y-shaped structure. One end of the locking component spans across both sides of the slide and is positioned and connected to the limiting groove on the energy compartment. The other end of the locking component is detachably connected to the crossbeam.

[0016] The present invention has the following advantages and beneficial effects:

[0017] The present invention provides an underwater robot slide-type energy tank structure, which has the advantages of simple structure, quick installation, easy maintenance, strong versatility and space saving. It saves the space required for the overall installation of the battery pack, and the roller slide structure can be installed quickly, improving work efficiency.

[0018] The present invention has strong structural versatility and can be widely applied to underwater robots with multiple battery packs; the structural components of the present invention are highly interchangeable, and the slider mechanisms on both sides of the battery adopt the same structure.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-2 As shown, the present invention provides an underwater robot slide-type energy compartment structure, including an energy compartment 1, individual batteries 2 and slides 18. Slides 18 are symmetrically arranged on both sides of the inner wall of the energy compartment 1. Multiple individual batteries 2 are sequentially introduced into the energy compartment 1 along the slides 18. A locking and fixing component is used to limit the multiple individual batteries 2 at the bow of the energy compartment 1.

[0030] The present invention provides an underwater robot slide-type energy tank structure, which has the advantages of simple structure, quick installation, easy maintenance, strong versatility and space saving. It saves the space required for the overall installation of the battery pack, and can be quickly installed through the slide, thus improving work efficiency.

[0031] Furthermore, a limiting block 20 is provided at the inner end of the slide 18 to limit the position of the individual battery 2.

[0032] like Figure 3As shown, in an embodiment of the present invention, the single battery 2 includes a battery body 5 and a slider mechanism 6 symmetrically arranged on both sides of the battery body 5. The slider mechanism 6 slides in cooperation with the slide rail 18 to reduce resistance and allow the battery body 5 to smoothly enter the energy compartment 1.

[0033] like Figure 4 As shown, in an embodiment of the present invention, the slider mechanism 6 includes a slider 7, a rolling bearing 14, and an automatic locking assembly. The slider 7 has a rolling bearing 14 on one side for cooperating with the slide rail 18. The automatic locking assembly is disposed on the slider 7 and is used to automatically lock the slider 7 in the slider mechanism 6 located on the front side.

[0034] In this embodiment, the slider 7 has a plate-like structure. One end face of the slider 7 has a protrusion 27, and the other end face has a groove 28. The other end of the slider 7 has a hook-body contact surface 25 perpendicular to the slider 7. After multiple individual batteries 2 are sequentially introduced into the energy compartment 1, adjacent sliders 7 are positioned by insertion through the protrusion 27 and the groove 28. The later-introduced slider 7 hooks onto the hook-body contact surface 25 of the earlier-introduced slider 7 through an automatic locking assembly, thereby achieving locking between adjacent sliders 7.

[0035] Furthermore, the back of the hook body contact surface 25 is an arc surface 26, which is used to guide the forward movement of the automatic locking assembly.

[0036] like Figure 4 As shown, in an embodiment of the present invention, the automatic locking assembly includes a hook body 8 and a spring 9, wherein the rear end of the hook body 8 is hinged to the front end of the slider 7 via a pin 11, and the front end of the hook body 8 is a hook-shaped part; the two ends of the spring 9 are respectively connected to the hook body 8 and the slider 7, and the spring 9 uses tension to make the hook-shaped part of the hook body 8 fit with the hook body contact surface 25 of the slider 7, and the arc surface 26 facilitates the smooth engagement of the hook body 8.

[0037] Preferably, such as Figure 4-5 As shown, the slider 7 is provided with two bearing mounting shafts 12, and each bearing mounting shaft 12 is equipped with a rolling bearing 14 through a bushing 13. The rolling bearing 14 is axially limited by a retaining ring 10 sleeved on the bearing mounting shaft 12, and the rolling bearing 14 serves as a sliding wheel for the single battery 2.

[0038] In this embodiment, the slider 7 has four countersunk holes for connecting to the battery body 5. The sliders 7 on both sides of the battery body 5 have a symmetrical structure, facilitating interchangeability when installed on both sides of the battery. The front end of the slider 7 has a protruding structure, and the rear end has a recessed structure. When the battery body 5 that enters later enters the energy compartment 1, the protrusion 27 on its slider 7 matches the recess 28 on the slider 7 that has already entered, achieving overall front-to-back and vertical positioning of the battery pack. Preferably, the pin 11 is installed on the upper end of the slider 7, and the hook 8 is fitted into it, with a retaining ring for positioning. A spring 9 connects the slider 7 and the hook 8. Its function is to allow the hook 8 to complete the engagement after the front and rear individual batteries 2 are installed in place, and to reset it through the spring 9, preventing the hook 8 from springing open during transportation and underwater navigation, which would affect battery disassembly. The hook 8 is installed on the upper end of the slider 7 to avoid interference with the slide rail 18.

[0039] like Figure 2 As shown, in an embodiment of the present invention, the locking and fixing assembly includes a crossbeam 15 and two locking members 16. The crossbeam 15 is disposed on the outside of the single battery 2 that is finally introduced into the energy compartment 1, and its two ends are respectively connected to the sliders 7 on both sides of the single battery 2. The two ends of the crossbeam 15 are positioned and connected to the energy compartment 1 through the two locking members 16.

[0040] like Figure 6 As shown in the embodiment of the present invention, a limiting groove 21 for positioning the locking member 16 is provided circumferentially on the inner side of the bow end of the energy compartment 1. The locking member 16 has a Y-shaped structure, with one end of the locking member 16 spanning both sides of the slide rail 18 and being positioned and connected to the limiting groove 21 on the energy compartment 1. The other end of the locking member 16 is detachably connected to the crossbeam 15 via a locking screw 17. The crossbeam 15 is installed on the outside of the single battery cell 2 that enters the energy compartment 1 last, serving as a pressure-bearing component for the battery pack. The Y-shaped opening of the locking member 16 avoids interference with the slide rail 18.

[0041] The present invention provides an underwater robot slide-type energy compartment structure, the specific installation method of which is as follows:

[0042] like Figure 7As shown, the slide 18 and the limiting block 20 have been pre-installed on the inner wall of the energy compartment 1. First, the bow section 22 of the underwater robot and the bow end cover 23 of the energy compartment 1 are removed. The battery track end face of the lifting bracket 4 is aligned with the front end face of the slide 18. The first single battery 2 is placed on the track of the lifting bracket 4 and pushed into the energy compartment 1. The rolling bearing 14 moves in the slide 18 on both sides. When the second single battery 2 is pushed in, the protrusion 27 at the front end of the slider 7 is inserted and fitted into the groove 28 at the rear end of the first single battery 2. At the same time, the second single battery 2 is automatically hooked to the slider 7 of the first single battery 2 through the hook body 8. Under the contraction force of the spring 9, the hook body 8 is pressed tightly. The cable 19 at the upper end of the single battery 2 is manually connected. Similarly, the subsequent groups of individual battery cells 2 are advanced sequentially. After the last individual battery cell 2 is installed, the locking component 16 is inserted into the limiting groove 21 at the front end of the energy compartment 1. The locking component 16 has threaded holes, and the locking screw 17 is screwed into the holes until it is tightened against the crossbeam 15 on the outside of the last individual battery cell 2. Multiple individual batteries 2 form a battery pack. Finally, the lifting bracket 4 is removed, and the bow cap 23 and bow section 22 are installed to complete the installation of the battery pack. The energy compartment 1 and the bow cap 23 form the pressure-resistant battery compartment of the underwater robot. During this process, the stern section does not need to be disassembled. Especially for the compartment structure with limited internal space, this installation process achieves automatic battery connection.

[0043] The battery pack disassembly process is the reverse of the above. Due to the connecting effect of the hook 8, each individual battery cell 2 can be pulled out smoothly in sequence. The rolling bearing 14 can also reduce the movement resistance. When the individual battery cell 2 is removed from the energy compartment 1, the hook 8 needs to be pulled open manually. Since the energy compartment 1 is installed in the middle of the underwater robot, when the battery pack needs to be disassembled, the bow section 22 of the underwater robot is separated, and the stern section does not need to be separated to achieve the replacement.

[0044] This invention provides a slide-type energy compartment structure for underwater robots, which has the advantages of simple structure, quick installation, easy maintenance, strong versatility and space saving. It saves the space required for the overall installation of the battery pack. The roller slide structure can be installed quickly, improving work efficiency. The structure of this invention has strong versatility and can be widely used in underwater robot multi-battery pack applications. The slider hook structure is particularly suitable for robot compartments with limited internal space, providing a good solution for saving internal space in the compartment.

[0045] The above description is merely an embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, extensions, etc., made within the spirit and principles of the present invention are included within the scope of protection of the present invention.
