[0037] The water surface floating object cleaning device (hereinafter referred to as the cleaning device) includes a shell, a battery pack, a propeller group and a cleaning group. The propeller group is powered by the battery pack, and the propeller group enables the shell to move on the water surface. When the shell moves, the cleaning group cleans the floating objects on the water surface.

[0038] When the existing cleaning equipment is in use, its battery pack and the propeller group are electrically connected through a connecting wire so that the battery pack can supply power to the propeller group; the battery pack is usually provided with a shell on the outside, and the connecting wire needs to pass through the shell to be connected to the battery. At this time, after the connecting wire passes through the shell to be connected to the battery, there is a certain gap at the connection between the connecting wire and the shell. This gap will cause water or gas with high moisture content to enter the shell through the gap between the connecting wire and the shell when the cleaning equipment is working on the water surface, thereby causing the battery to become damp and cause battery damage.

[0039] The utility model provides a connecting wire which is mainly used for connecting a storage battery and a motor. A shell is arranged outside the storage battery, and the connecting wire passes through the shell and is connected with the storage battery.

[0040] See also Figure 1 , Figure 4 In one embodiment of the present utility model, the connecting line includes:

[0041] The wire core 100 has a connection end 110, wherein the connection end 110 of the wire core 100 is connected to the battery. In this embodiment, the wire core 100 can be a wire core 100 with an insulating layer, or a wire core 100 of a single copper wire, which is not limited here.

[0042] The protective sleeve 200 is integrally formed on the outside of the wire core 100. Depending on the type of the above-mentioned wire core 100, whether other protective layers need to be added when the protective sleeve 200 is integrally formed on the wire core 100. When other protective layers need to be added, it is necessary to wrap the protective layer on the outside of the wire core 100 before the protective sleeve 200 is integrally formed on the outside of the wire core 100.

[0043] The connecting structure 300 is fixed on the outside of the protective sleeve 200, and the connecting structure 300 and the protective sleeve 200 are sealed. There is no limitation on the way the connecting structure 300 is fixed on the outside of the protective sleeve 200. It can be fixed by bonding, or the connecting structure 300 and the protective sleeve 200 are fixed by hot melting, or the connecting structure and the protective sleeve 200 are fixed by integral molding, etc. When the above three methods are used for fixing, after the connecting structure 300 and the protective sleeve 200 are fixed together, the connection between the two is sealed. If other methods are used for fixing, it is necessary to seal the connection between the connecting structure 300 and the protective sleeve 200 by other means. The sealing treatment of other means includes but is not limited to setting a sealing ring 350, setting (applying) a sealing layer, etc. The housing 400 has a mounting hole 410, and the connecting structure 300 is interference-fitted with the mounting hole 410. When the connecting wire is connected to the battery, the connecting wire is first assembled with the housing 400, and the connecting structure 300 is interference-fitted with the mounting hole 410 in the housing 400 during the assembly process. That is, the connecting wire is inserted into the mounting hole 410, and the interference fit between the connecting structure 300 and the mounting hole 410 can avoid the existence of a gap at the connection between the connecting wire and the housing 400, thereby solving the technical problems existing in the prior art. At the same time, the connecting structure 300 and the protective cover 200 in the present application are made of the same material, or are materials that can be melted by heating, which is not limited here.

[0044] In order to achieve interference fit between the connection structure 300 and the mounting hole 410, the connection structure 300 can be inserted into the mounting hole 410 by overcoming the assembly resistance; or the connection structure 300 can be inserted into the mounting hole 410 by thermal expansion and contraction, and then the connection structure can be interference fit with the mounting hole 410 after the connection mechanism returns to its initial state.

[0045] The technical solution of the utility model adopts a method of fixing a connecting structure 300 on the outside of the protective sleeve 200. When the connecting line passes through the shell 400 and is installed with the battery, the connecting structure 300 and the installation hole 410 in the shell 400 are interference fit, and the interference fit can avoid the existence of a gap at the connection between the connecting line and the shell 400. In this way, when the cleaning equipment is working on the water surface, it can avoid water or gas with high moisture content from entering the shell 400 through the gap between the connecting line and the shell 400, thereby causing the battery to become damp and causing damage to the battery. Therefore, the technical problems existing in the prior art can be solved.

[0046] In one embodiment, reference Figure 1 , Figure 2 The connection structure 300 includes a first ring body 310, a second ring body 320, a third ring body 330, and a fourth ring body 340 which are sequentially arranged along the axial direction of the wire core 100. The first ring body 310, the second ring body 320, the third ring body 330, and the fourth ring body 340 are arranged in a step-like manner. Specifically, the step-like manner means that, in the axial cross section along the connection line, the first ring body 310 is higher or lower than the second ring body 320, the second ring body 320 is higher or lower than the third ring body 330, and the third ring body 330 is higher or lower than the fourth ring body 340. The first ring body 310 is arranged near the connection end 110 of the wire core 100. In this embodiment, the first ring body 310 is lower than the second ring body 320, the third ring body 330 is lower than the second ring body 320, and the fourth ring body 340 is higher than the third ring body 330 and higher than the second ring body 320. This is to facilitate the assembly between the connection structure 300 and the mounting hole 410 and to facilitate the use of the staff. In this embodiment, since the connection structure 300 is arranged in a step-like manner, the corresponding mounting holes 410 are also arranged in a step-like manner.

[0047] In one embodiment, reference Figure 1 , Figure 2 The first ring body 310 is tapered at one end close to the connection of the wire core 100. Since the first ring body 310 is arranged close to the connection end 110 of the wire core 100, that is, when the connecting wire is assembled, the first ring body 310 will be inserted into the mounting hole 410 first. At this time, under the action of the first ring body 310, the connecting structure 300 can be conveniently guided to be inserted into the mounting hole 410, thereby facilitating the assembly between the connecting wire and the shell 400 and improving the assembly efficiency.

[0048] In one embodiment, reference Figure 4 , Figure 6The connection structure 300 also includes a protrusion 370, which is fixed to the outside of the first ring body 310, and a step 360 is formed between the protrusion and the second ring body 320. Specifically, when viewed along the axial section of the connection line, the protrusion is located above the second ring body 320, and the mounting hole 410 is also provided with a limiting portion 420 corresponding to the step 360. After the connection line and the housing 400 are assembled, in order to prevent the connection line from detaching from the mounting hole 410, the step 360 and the limiting portion 420 can prevent the connection line from falling off the mounting hole 410, thereby causing a gap to appear at the connection between the connection line and the mounting hole 410. In this embodiment, reference Figure 5 , Figure 7 There is no specific limitation on the structure of the limiting portion 420 , and the limiting portion 420 may be an end portion of the mounting hole 410 , or an inner wall of the mounting hole 410 .

[0049] In one embodiment, reference Figure 4 , Figure 6 The protrusions are multiple and are distributed in a circumference, so as to increase the area of ​​the step 360, thereby increasing the contact area between the step 360 and the stopper 420, so that the connection between the connecting wire and the housing 400 is more stable. In other embodiments, the multiple protrusions can be closely arranged to form a ring-like structure sleeved outside the first ring body 310.

[0050] In one embodiment, reference Figure 1 , Figure 2 , the connection structure 300 also includes a sealing ring 350, which is arranged outside the third ring body 330. Specifically, when the connection line and the housing 400 are assembled together, the sealing ring 350 is located in the mounting hole 410. Under the action of the sealing ring 350, the sealing effect between the connection structure 300 and the mounting hole 410 can be further improved, and at the same time, under the action of the sealing ring 350, the connection structure 300 and the mounting hole 410 can be interference-fitted. And the sealing ring 350 is movably sleeved outside the third ring body 330. In this way, when the connection structure 300 is assembled with the mounting hole 410, it is convenient for the staff to insert the connection structure 300 into the mounting hole 410. In other embodiments, the sealing ring 350 can be fixed outside the third ring body 330. In this way, during the assembly process, if the staff assembles the connection structure 300 with the mounting hole 410 by overcoming the impedance force, the staff needs to use a larger force to overcome the impedance force.

[0051] In one embodiment, reference Figure 2 , Figure 4The second ring body 320, the third ring body 330, and the fourth ring body 340 are combined to form a concave structure, and the sealing ring 350 is arranged in the concave structure. This is arranged to facilitate the installation of the sealing ring 350. At the same time, during the assembly process, the sealing ring 350 can be limited under the restriction of the concave structure to avoid the sealing ring 350 misalignment and sealing failure after the connection structure 300 and the installation hole 410 are assembled. And through the interference fit between the sealing ring 350 and the installation hole 410, when the sealing ring 350 has problems such as aging after long-term use, the staff can replace the sealing ring 350, thereby further extending the service life of the connection structure 300, and then extending the service life of the connecting line.

[0052] In one embodiment, reference Figure 2 , Figure 4 The outer diameter of the fourth ring body 340 is greater than the outer diameters of the second ring body 320 and the third ring body 330. In this way, when the connecting wire is inserted into the mounting shell, the fourth ring body 340 can effectively block the sealing ring 350, so that the sealing ring 350 is in the concave structure, thereby ensuring the position of the sealing ring 350 after assembly. Specifically, the fourth ring body 340 and the mounting hole 410 can be transitionally matched, and the fourth ring body 340 can seal the mounting hole 410 under the effect of the transitional fit.

[0053] In one embodiment, reference Figure 2 The connection structure 300 is integrally formed, which can improve the strength of the connection structure 300 and reduce the production cost of the connection structure 300.

[0054] In one embodiment, reference Figure 2 The connection structure 300 and the protective sleeve 200 are integrally formed to reduce the production cost of the connection line. At the same time, the one-piece fixing method can also achieve the best sealing between the connection structure 300 and the protective sleeve 200, compared with other fixing methods such as bonding.

[0055] The utility model also proposes a waterproof structure for connecting wires, referring to Figure 4 , Figure 5The waterproof structure of the connecting wire includes a housing 400 and a connecting wire. The specific structure of the connecting wire refers to the above embodiment. Since the waterproof structure of the connecting wire adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the housing 400 is provided with a mounting hole 410, and the connecting wire is interference-fitted with the mounting hole 410. Specifically, the sealing ring 350 in the connecting wire is interference-fitted with the mounting hole 410. The housing 400 also has a limiting portion 420 that cooperates with the step 360 (refer to Figures 4 to 7 ).

[0056] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
