[0025] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0026] In conjunction with the attached drawings, the present utility model is introduced in detail.

[0027] When the present utility model is specifically implemented, it provides an insulation installation grounding structure for ship electrical equipment, including a protective cover body 1 and electrical equipment 2. The bottom end of the electrical equipment 2 is insulated and grounded to the ship deck through an insulating pad 3, an aluminum alloy bracket 4, and a grounding component 5. The edge of the ship deck extends upward and is fixed with a first limiting component 6. A second limiting component 7 is arranged on the outer side of the protective cover body 1. The bottom end of the protective cover body 1 is position-locked with the ship deck through the cooperation of the second limiting component 7 and the first limiting component 6. A plurality of sealing components 8 are arranged at the contact position between the protective cover body 1 and the ship deck. By adding a second limiting component 7 and a first limiting component 6 between the protective cover body 1 and the ship deck for position locking, the present utility model can achieve the rapid installation and disassembly of the protective cover body outside the electrical equipment, and can protect the electrical equipment installed inside through the protective cover body.

[0028] The present utility model is provided with a plurality of sealing components 8 at the contact position between the protective cover body 1 and the ship deck, which can improve the sealing performance between the protective cover body and the ship deck, and prevent external seawater from entering the interior of the protective cover and affecting the electrical equipment. The ship deck is as shown at Figure 3 position B in the figure.

[0029] Embodiment:

[0030] The specific working principle of the present utility model is as follows. The present utility model provides an insulated installation and grounding structure for ship electrical equipment. The electrical equipment is installed on the ship deck through an insulating pad 3, an aluminum alloy bracket 4, and a grounding component 5, thereby forming an insulated grounding installation structure. And a plurality of sealing components 8 are provided at the contact position between the protective cover body 1 and the ship deck, which can improve the sealing performance between the protective cover body and the ship deck, and prevent external seawater from entering the interior of the protective cover and affecting the electrical equipment.

[0031] Among them, a first limiting component 6 and a second limiting component 7 are installed between the protective cover body 1 and the ship deck, which can realize the rapid installation and disassembly between the protective cover body and the ship deck, and no additional other components and installation tools are required, which can greatly save the corresponding disassembly and assembly time, simplify the disassembly and assembly steps of the staff, and save the disassembly and assembly time of the protective cover body.

[0032] Combined with the attached drawings, the second limiting component 7 on the ship deck includes a housing 19, a limiting button 9, a first limiting spring 10, and a second limiting spring 11. The limiting button 9 extends into the interior of the housing 19 and inserts the first limiting spring 10. The inner side of the first limiting spring 10 is fixed inside the housing 19, and its outer side extends out of the housing 19. A fixing column 12 is arranged inside the housing 19. The second limiting spring 11 is sleeved on the fixing column 12 and is located below the first limiting component 6. The top end of the limiting button 9 extends upward to form a locking component 13. The bottom end of the first limiting component 6 is provided with a clamping groove 14 that cooperates with the locking component 13 on the limiting button 9. An opening 15 is provided at the top end of the housing 19.

[0033] The above structure is the specific internal structure of the first limiting component and the second limiting component. When the protective cover body 1 needs to be installed, the protective cover body 1 can be directly pressed into the opening 15 at the top end of the housing 19. Under the action of the first limiting spring 10, the locking component 13 on the limiting button 9 cooperates with the clamping groove 14 at the bottom end of the protective cover body 1 to realize position locking.

[0034] When it is necessary to remove the corresponding protective cover 1, the limit button 9 can be pressed inward by hand. The limit button 9 moves inward to squeeze the first limit spring 10, driving the locking component 13 at the top of the limit button 9 to move inward, so that the locking component at the top of the limit button 9 is disengaged from the restraint of the engaging groove 14 at the bottom of the protective cover 1. At this time, since the second limit spring 11 is sleeved on the fixed column 12 and is located below the first limiting component 6, the second limit spring 11 exerts an upward elastic force on the protective cover 1, and the separation of the protective cover 1 from the ship deck can be realized. The above structure only needs to press the button by hand to achieve one-key disassembly, which not only saves the disassembly time of the protective cover, but also simplifies the disassembly process of the protective cover.

[0035] As a further elaboration of the present invention, a groove 16 is provided at the bottom end of the protective cover 1, and the sealing component 8 is installed in the groove 16. The groove 16 is provided with 2 or 3 groups. The insulating pad 3 is made of insulating rubber material. Through the above-mentioned multiple sealing components, the sealing performance of the connection between the protective cover and the ship deck can be increased, preventing seawater from entering the inside of the protective cover and thus damaging the performance of the electrical equipment. The above structure can protect the electrical equipment and avoid the influence of the external environment on the electrical equipment. Among them, when there are 2 groups of grooves, two corresponding sealing components are arranged in the grooves, which can meet the sealing requirements of the protective cover. When the corresponding number is 3 groups, the sealing performance of the protective cover is better.

[0036] As a further elaboration of the present invention, a wiring hole 17 is provided at the top end of the protective cover 1, and a protective cover 18 is detachably connected to the outside of the wiring hole 17. By providing the wiring hole 17 with the above structure, the electrical equipment can be normally wired. At the same time, the wiring hole 17 can be shielded by the protective cover 18 to prevent rainwater from entering the inside of the protective cover and affecting the normal use of the electrical equipment.

[0037] As a further elaboration of the present invention, a plurality of silicone bumps are provided on the contact surface between the locking component on the limit button and the engaging groove at the bottom end of the protective cover to increase the frictional force between the locking component and the engaging groove, making the connection between the two more stable.

[0038] Combined Figure 3 、 Figure 7 As can be seen, a recessed groove body 20 is provided on the ship deck, and the bottom end of the protective cover 1 extends into the recessed groove body 20 on the ship deck. The sealing component is installed at the mating part of the bottom end of the protective cover 1 and the recessed groove body 20 by using a sealing strip or a sealing ring.

[0039] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and design, without creative efforts, structural manners and embodiments similar to the technical solution without departing from the gist of the creation of the present utility model, they shall fall within the protection scope of the present utility model.
