Description

Technical Field

[0001] This utility model belongs to the technical field of marine electrical cabinets, and more specifically, it relates to a protective device for marine electrical cabinets. Background Technology

[0002] Marine electrical cabinets are steel cabinets used to protect components and ensure their proper functioning. With the increasing electrification and automation of ships, the power of ship power stations is growing, making marine electrical cabinets even more crucial. During ship navigation, these cabinets can sway or tip over, necessitating the use of electrical cabinet stability protection devices. Existing marine electrical cabinets exhibit limited stability, potentially causing swaying or even tipping during ship movement, leading to equipment damage and significantly reducing equipment stability and usability.

[0003] Existing technology includes a device entitled "A Stability Protection Device for Marine Electrical Cabinets," with publication number CN214481609U. This device discloses a stability protection device for marine electrical cabinets, featuring a protective sleeve with a baffle plate fixed to the top, a connecting mechanism extending outwards embedded inside the sleeve, and a stabilizing mechanism connected to the bottom. The connecting mechanism includes a connecting sleeve, a connecting spring connected to one inner wall of the connecting sleeve, a connecting pad connected to the other end of the connecting spring, and a movable column fixed to the other side of the connecting pad. This invention, with its connecting mechanism, ensures a secure connection between the protective sleeve and the marine electrical cabinet, enhancing the stability of the cabinet and ensuring a stable placement structure. The stabilizing mechanism also ensures a secure installation between the protective sleeve, the anti-slip pad, and the counterweight plate. The anti-slip pad increases the friction between the marine electrical cabinet and the protective sleeve in contact with the ground, thus improving the stability of the marine electrical cabinet. However, this technology does not relate to the technical solution of this application. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a ship electrical cabinet protection device that is simple in structure, can fix the electrical cabinet, ensures stability, prevents the electrical cabinet from shaking during ship movement, meets the needs of ship use, and can be applied to the protection of electrical cabinets of various models and sizes, thus improving the versatility of the device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model is a protective device for a marine electrical cabinet, including a protective frame and a support. The protective frame and the support frame are connected by multiple connecting shafts. The lower end of the connecting shaft is connected to the support frame. A fixing nut is screwed onto the upper part of the connecting shaft and a support nut is screwed onto the lower part of the connecting shaft.

[0007] The support frame is a frame structure, and a first fixing plate and a second fixing plate are provided on the inner side of the support frame. Each end of the first fixing plate and the second fixing plate is movably locked into the sliding groove of the support frame.

[0008] The first limiting screw on one side of the support frame is screwed through the first limiting screw hole and contacts the first fixing plate, and the second limiting screw on the other side of the support frame is screwed through the second limiting screw hole and contacts the second fixing plate.

[0009] The bottom of the protective frame contacts the top of the electrical cabinet, and the bottom of the electrical cabinet is clamped between the first fixing plate and the second fixing plate.

[0010] The support frame is fixedly connected to the hull by bolts.

[0011] The protective frame is a square structure, with connecting screw holes at each corner. The support frame is also a square structure, with the upper end of each connecting shaft screwed through the corresponding connecting screw hole, and the lower end of each connecting shaft fixedly connected to the corresponding corner of the support frame.

[0012] The first fixing plate and the second fixing plate are bonded together with a first fixing pad on their opposing surfaces, and the second fixing plate is bonded together with a second fixing pad on their opposing surfaces. The first fixing pad and the second fixing pad are rubber pads.

[0013] The bottom of the protective frame is bonded with a protective pad, which is a rubber pad.

[0014] A washer is fitted on the connecting shaft above the support nut, and the outer diameter of the washer is larger than the outer diameter of the support nut.

[0015] Multiple first limiting screws and multiple second limiting screws are provided.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] The marine electrical cabinet protection device of this utility model is structurally designed by fabricating a protective frame and a support frame, which are connected by multiple connecting shafts. The lower end of the connecting shaft is connected to the support frame, and the lower end of the connecting shaft is reliably connected to the support frame. The support frame can be fixedly mounted on the hull. Thus, when the electrical cabinet needs to be fixed, the lower end of the electrical cabinet is limited by the support frame, and the upper end of the electrical cabinet is located at the bottom of the protective frame and limited by the protective frame. A fixing nut is screwed onto the connecting shaft at the upper position of the protective frame, and a support nut is screwed onto the connecting shaft at the lower position of the protective frame. The fixing nut and the support nut are screwed into contact with the protective frame, thereby limiting the position of the protective frame and the connecting shaft and ensuring reliable positioning of the electrical cabinet. Specifically, by using a protective frame that can move up and down along the connecting shaft, the height of the protective frame is adjusted according to the different models and sizes of electrical cabinets when fixing the electrical cabinet. This ensures that the bottom of the protective frame is in close contact with the top of the electrical cabinet. By rotating and moving the fixing nut and the support nut, the bottom of the fixing nut contacts the top of the protective frame, and the top of the support nut contacts the bottom of the protective frame, thus limiting the position of the protective frame and fixing the electrical cabinet. By connecting the bottom of the connecting shaft to the support frame, the connecting shaft will not move or shift relative to the support frame. The support frame is connected to the hull, ensuring that the electrical cabinet will not sway during the movement of the ship after being limited, effectively eliminating the possibility of tipping over, avoiding damage to the equipment, and improving the reliability of the electrical cabinet.

[0025] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0026] As attached Figure 1 -Appendix Figure 5As shown, this utility model is a protective device for a marine electrical cabinet, including a protective frame 1 and a support frame 2. The protective frame 1 and the support frame 2 are connected by multiple connecting shafts 3. The lower end of the connecting shaft 3 is connected to the support frame 2. A fixing nut 4 is screwed onto the upper part of the connecting shaft 3 and a support nut 10 is screwed onto the lower part of the connecting shaft 3. The above structure addresses the shortcomings of the prior art and proposes an improved technical solution. In the structural setup, a protective frame 1 and a support frame 2 are fabricated separately. The protective frame 1 and the support frame 2 are connected by multiple connecting shafts 3. The lower end of the connecting shaft 3 is connected to the support frame 2, and the lower end of the connecting shaft 3 is reliably connected to the support frame 2. The support frame 2 can be fixedly mounted on the hull. In this way, when it is necessary to fix the electrical cabinet 5, the lower end of the electrical cabinet 5 is limited by the support frame 2, and the upper end of the electrical cabinet 5 is located at the bottom of the protective frame 1 and limited by the protective frame 1. The connecting shaft 3 is located at the upper position of the protective frame 1 and the supporting nut 10 is located at the lower position of the protective frame 1. The fixing nut 4 and the supporting nut 10 are respectively tightened to contact the protective frame 1, thereby limiting the protective frame 1 and the connecting shaft 3 and ensuring reliable positioning of the electrical cabinet 5. Specifically, by using a protective frame 1 that can move up and down along the connecting shaft 3 to fix the electrical cabinet 5, the height of the protective frame 1 is adjusted according to the different models and sizes of electrical cabinets 5, ensuring that the bottom of the protective frame 1 is in close contact with the top of the electrical cabinet 5. By rotating and moving the fixing nut 4 and the support nut 10, the bottom of the fixing nut 4 contacts the top of the protective frame 1, and the top of the support nut 10 contacts the bottom of the protective frame 1, thus limiting the position of the protective frame 1 and fixing the electrical cabinet 5. By connecting the bottom of the connecting shaft 3 to the support frame 2, the connecting shaft 3 will not move or shift relative to the support frame 2. The support frame 2 is connected to the hull, ensuring that after the electrical cabinet 5 is limited, it will not shake during ship movement, effectively eliminating potential tipping problems, avoiding equipment damage, and improving the reliability of the electrical cabinet. The ship electrical cabinet protection device described in this utility model has a simple structure, can fix the electrical cabinet, ensure stability, and prevent the electrical cabinet from shaking during ship movement, meeting the needs of ship use. It is also applicable to the protection of electrical cabinets of various models and sizes, improving versatility.

[0027] The support frame 2 is a frame structure. A first fixing plate 6 and a second fixing plate 13 are provided on the inner side of the support frame 2. Each end of the first fixing plate 6 and the second fixing plate 13 is movably engaged in the sliding groove 18 of the support frame 2. A first limiting screw 7 on one side of the support frame 2 is screwed through a first limiting screw hole 14 and abuts against the first fixing plate 6. A second limiting screw 11 on the other side of the support frame 2 is screwed through a second limiting screw hole 15 and abuts against the second fixing plate 13. With this structure, when the electrical cabinet 5 needs to be positioned, the first fixing plate 6 and the second fixing plate 13 are moved, contacting the lower side of the electrical cabinet 5. Then, the first limiting screw 7 and the second limiting screw 11 are rotated, with the first limiting screw 7 abutting against the first fixing plate 6 and the second limiting screw 11 abutting against the second fixing plate 13. The first fixing plate and the second positioning plate clamp and fix the electrical cabinet 5 from both sides, improving the stability of the electrical cabinet 5.

[0028] The bottom of the protective frame 1 contacts the top of the electrical cabinet 5, and the bottom of the electrical cabinet 5 is clamped between the first fixing plate 6 and the second fixing plate 13. This structure allows for the clamping of electrical cabinets of different models and sizes by adjusting the positions of the first and second fixing plates.

[0029] The support frame 2 is fixedly connected to the hull by bolts. In this structure, the support frame is fixedly connected to the hull, preventing swaying or movement. The connecting shaft 3 is fixedly connected to the support frame 2, and then the protective frame 1 is connected to the connecting shaft 3. Once the electrical cabinet 5 is in place, the protective frame 1 is reliably fixed. Through the cooperation of the protective frame, connecting shaft, and support frame, the electrical cabinet is reliably limited.

[0030] The protective frame 1 is a square structure, with connecting screw holes 12 at each corner. The support frame 2 is also square, with each connecting shaft 3 having its upper end screwed through the corresponding connecting screw hole 12, and its lower end fixedly connected to the corresponding corner of the support frame 2. In this structure, four connecting shafts are provided, and each connecting shaft 3 is a screw structure, allowing for the screwing on of fixing nuts and support nuts to position the protective frame at different locations on the connecting shafts.

[0031] A first fixing pad 17 is bonded to the opposing surfaces of the first fixing plate 6 and the second fixing plate 13, and a second fixing pad 16 is bonded to the opposing surfaces of the second fixing plate 13 and the first fixing plate 6. Both the first fixing pad 17 and the second fixing pad 16 are rubber pads. This structure, through the rubber first fixing pad 17 and the second fixing pad 16, improves the tightness of contact between the first fixing plate 6, the second fixing plate 13, and the side of the electrical cabinet 5. The first fixing pad 17 and the second fixing pad 16 can reduce the pressure on the electrical cabinet 5 at the contact point, preventing damage due to excessive pressure on the side of the electrical cabinet 5.

[0032] The bottom of the protective frame 1 is bonded with a protective pad 8, which is a rubber pad. This structure, by using the rubber protective pad 8, improves the tightness of the contact between the protective frame 1 and the top of the electrical cabinet 5, thus better securing the electrical cabinet 5. The protective pad 8 also reduces the pressure on the electrical cabinet 5 at the contact point, thereby preventing damage due to excessive pressure on the top of the electrical cabinet 5.

[0033] A washer 9 is fitted onto the connecting shaft 3 above the support nut 10. The outer diameter of the washer 9 is larger than that of the support nut 10. This structure, by using the washer 9, effectively disperses pressure, reduces pressure at individual contact points, prevents screws and other components from loosening, provides better support for the bottom of the protective frame 1, and improves the limiting effect on the protective frame 1.

[0034] Multiple first limiting screws 7 and multiple second limiting screws 11 are provided.

[0035] The protective device for the ship's electrical cabinet described in this utility model is structurally designed with a protective frame 1 and a support frame 2. The protective frame 1 and the support frame 2 are connected by multiple connecting shafts 3. The lower end of the connecting shaft 3 is connected to the support frame 2, and the lower end of the connecting shaft 3 is reliably connected to the support frame 2. The support frame 2 can be fixedly mounted on the hull. Thus, when it is necessary to fix the electrical cabinet 5, the lower end of the electrical cabinet 5 is limited by the support frame 2, and the upper end of the electrical cabinet 5 is located at the bottom of the protective frame 1 and limited by the protective frame 1. The connecting shaft 3 is located at the upper position of the protective frame 1 and the supporting nut 10 is located at the lower position of the protective frame 1. The fixing nut 4 and the supporting nut 10 are respectively tightened to contact the protective frame 1, thereby limiting the protective frame 1 and the connecting shaft 3 and ensuring reliable positioning of the electrical cabinet 5. Specifically, by using a protective frame 1 that can move up and down along the connecting shaft 3 to fix the electrical cabinet 5, the height of the protective frame 1 is adjusted according to the different models and sizes of the electrical cabinet 5, so that the bottom of the protective frame 1 is in close contact with the top of the electrical cabinet 5. By rotating and moving the fixing nut 4 and the support nut 10, the bottom of the fixing nut 4 is in contact with the top of the protective frame 1, and the top of the support nut 10 is in contact with the bottom of the protective frame 1, thereby limiting the position of the protective frame 1 and fixing the electrical cabinet 5. By connecting the bottom of the connecting shaft 3 to the support frame 2, the connecting shaft 3 will not move or shift relative to the support frame 2. The support frame 2 is connected to the hull, thus fixing the support frame 2. After limiting the position of the electrical cabinet 5, the electrical cabinet 5 will not shake during the movement of the ship, effectively eliminating the possible tipping problem, avoiding damage to the equipment, and improving the reliability of the electrical cabinet.
