In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0028] The utility model provides a shore power cable reel for a tugboat, comprising a sunscreen 1, a reel assembly, a stopper 7 and a closing cover 8 installed on the deck of the tugboat.
[0029] A door 2 with a lock is hinged on one side of the sunshade 1. Both the sunshade 1 and the door 2 are made of heat-insulating materials. A reel assembly is arranged inside the sunshade 1; the reel assembly includes a support frame 3, a barrel 4, a motor 5 and a support block 6. One end of the barrel 4 is mechanically connected to the motor 5, and the end of the barrel 4 away from the motor 5 is rotatably connected to the support block 6 through a bearing. The support frame 3 is fixed below the motor 5 and the support block 6 by bolt connection. An electric cable 11 is wound around the barrel 4. By combining the above-mentioned attachments Figure 1 and attached Figure 3 It can be seen that when the cable is not in operation, it is stored in the sun-proof cover 1, and the sun-proof cover 1 protects the cable from the sun and heat, thereby effectively increasing the service life of the cable.
[0030] The opening and closing door 2 is provided with a long through hole 201 at a position corresponding to the barrel 4. One end of the cable head of the cable 11 extends out of the sunshade 1 through the long through hole 201. The stopper 7 is mainly composed of two symmetrical plates, which are connected and fixed by bolts, and the cable 11 is clamped between the two plates; the width of the stopper 7 is greater than the width of the long through hole 201; the stopper 7 is installed on one side of the cable head of the cable 11 and is located outside the sunshade 1. Figure 2 and attached Figure 7 It can be seen that when the cable is not in working state, one end of the cable head of the cable 11 is limited by the position of the limiter 7 and is located outside the opening and closing door 2, that is, outside the sunshade 1, so that the staff can take the cable head to pull the cable 11 during work; and the length and position design of the long through hole 201 are flush with the barrel 4, which ensures the smoothness of the cable 11 during the pulling process.
[0031] A vertical slideway 9 is welded to the outside of the opening and closing door 2, and the slideways 9 are symmetrically distributed at both ends of the long through hole 201. A hook-shaped slideway 901 is provided on the slideway 9; a support 10 is provided at the lower end of the slideway 901. The closing cover 8 is a rectangular cover with an opening on one side, and the opening side of the closing cover 8 faces the opening and closing door 2; the closing cover 8 is made of heat-insulating material. Slide blocks 801 that match the slideway 901 are welded at both ends of the closing cover 8, and the closing cover 8 is slidably arranged between the slideways 9 through the slide blocks 801 and the slideway 901. A handle is provided on the side of the closing cover 8 away from the opening and closing door 2.
[0032] As can be seen from the above, when the cable is not in working state, the closing cover 8 is used to shield the cable head end of the cable 11 extending out of the opening and closing door 2 through the long through hole 201, thereby providing sun protection, heat insulation and protection. At this time, the sliders 801 at both ends of the closing cover 8 are limited and fixed at the hook ends of the slide groove 901.
[0033] When the cable is in working state, the staff moves the closing cover 8 by operating the handle, and the closing cover 8 slides and cooperates with the slide groove 901 through the slider 801 until the slider 801 moves to the bottom of the slide groove 901. At this time, the slider 801 is located above the support 10, and the closing cover 8 is located below the outer side of the opening and closing door 2, which does not hinder the staff's operation when pulling the cable. Among them, when the closing cover 8 passes through the hook of the slide groove 901 during the movement, the closing cover 8 will be pulled away from the cable head end of the cable 11, so that the closing cover 8 will not interfere with the cable head end during the falling process.
[0034] The support 10 includes an upper support plate 1001, a lower support plate 1002 and a spring 1003. The spring 1003 is connected and fixed between the upper support plate 1001 and the lower support plate 1002. The upper support plate 1001 and the lower support plate 1002 are made of TPU material. Fig. 9 It can be seen that the support 10 supports the closing cover 8 located at the lower outer side of the opening and closing door 2 when the cable is in the working state. When the staff moves the closing cover 8 to fall, they can let go without bending over. The closing cover 8 falls freely, and the slider 801 hits the support 10. The support 10 uses its elastic force to reduce the impact on the slider 801.
[0035] The specific usage and function of this embodiment are as follows:
[0036] When the cable is in a non-working state, the cable 11 is completely shielded by the sunshade 1 , the opening and closing door 2 and the closing cover 8 , thereby achieving sun protection and heat insulation for the cable 11 .
[0037] When the cable needs to be used, the staff moves the closing cover 8 by operating the handle. When the slider 801 passes through the hook of the slide slot 901, the closing cover 8 and the cable head end of the cable 11 are pulled apart, and the positions of the two no longer interfere with each other. At this time, the staff releases the handle to allow the closing cover 8 to fall freely to the top of the support 10. At this time, the closing cover 8 is located below the outer side of the opening and closing door 2; after that, the staff pulls the cable 11 outward through the cable head end of the opening and closing door 2, and the cable 11 on the barrel 4 is continuously pulled out of the sunshade 1 from the long through hole 201 until the cable head is dropped onto the dock and connected to the shore power grid for power supply;
[0038] After the power is taken off, the staff manually operates the motor 5 to drive the barrel 4 to rotate. The barrel 4 pulls the cable 11 through the long through hole 201 and rewinds it on the barrel 4 until the limiter 7 contacts the opening and closing door 2. Next, the staff operates the handle to lift the closing cover 8 back to cover the cable head end of the cable 11. At this time, the sliders 801 at both ends of the closing cover 8 are limited and fixed at the hook ends of the slide groove 901, completing the covering of the cable head end of the cable 11 by the closing cover 8.
[0039] In summary, compared with the prior art, the utility model achieves the purpose of sun protection for the cables on the tugboat shore power cable drum, thereby increasing the service life of the cables.
