[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. The specific structural and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments described herein.

[0026] like Figure 1 As shown, a power receiving device, in an optional embodiment, the power receiving device includes a power supply slide wire 100, a current collector 200, a lead-out cable 300 and a connecting frame, wherein:

[0027] The power supply slide line 100 is used to connect the power supply source. The power supply slide line 100 is arranged on the moving path of the mobile electrical appliance. Through the extended arrangement of the power supply slide line 100, the movement process of the electrical appliance can be carried out with power on in a larger range, which is of great significance in continuous operations at multiple stations and greatly improves operating efficiency and convenience.

[0028] The current collector 200 is arranged in plurality at intervals, and the current collector 200 is electrically connected to the power supply slide line 100 and can move on the power supply slide line 100. The current collector 200 can move on the power supply slide line 100 along the extension direction of the power supply slide line 100, and the current collector 200 can always remain electrically connected to the power supply slide line 100 during the movement process to obtain a stable power supply state.

[0029] The collector 200 is an electrical device used to collect, gather or transmit electric current, and is generally used in various electric machinery and electric power equipment such as motors, generators, motors, rail transit systems, etc. Its main function is to collect current from one or more sources into a single circuit or wire in order to effectively transmit electrical energy or perform specific electrical operations.

[0030] The export cables 300 are electrically connected to the multiple collectors 200 respectively, and one end of the export cables 300 is used to electrically connect to the electrical equipment. The export cables 300 are electrically connected to the collectors 200 respectively. Among the multiple collectors 200, only one collector 200 is needed to be stably electrically connected between the power supply slide line 100 and the export cables 300, so as to maintain a stable power supply effect between the export cables 300 and the power supply slide line 100. Therefore, the electrical equipment connected to the export cables 300 can still receive power stably even if there is a collector 200 that is unstable in connection with the power supply slide line 100, under the premise that only one collector 200 is stably electrically connected between the power supply slide line 100 and the export cables 300.

[0031] The connecting frame is connected to the multiple current collectors 200 and drives the multiple current collectors 200 to move synchronously. The connecting frame is respectively connected to the multiple current collectors 200, and under the connecting action of the connecting frame, the relative spacing between the multiple spaced current collectors 200 can be kept stable, and when one current collector 200 needs to be moved, other current collectors 200 can also be moved synchronously under the action of the connecting frame to maintain the relative position relationship between adjacent current collectors 200, avoid the movement of the current collectors 200 causing the distance between the current collectors 200 to be shortened and at the same time be at a virtual contact point, thereby improving reliability. At the same time, when the multiple current collectors 200 are moved, the operating difficulty is reduced and the operating efficiency is improved.

[0032] In an optional embodiment, the working principle of the power receiving device in the present application is: by arranging a plurality of spaced-apart current collectors 200 on the power supply slide 100, the current collectors 200 are electrically connected to the power supply slide 100 and can move on the power supply slide 100, and there are also lead-out cables 300 respectively electrically connected to the plurality of current collectors 200, and one end of the lead-out cable 300 is used to electrically connect to the power-consuming equipment, and a connecting frame is connected to the plurality of current collectors 200 at the same time, and the connecting frame can drive the plurality of current collectors 200 to move synchronously, and the power supply slide 100 is used to connect the power supply source during operation, and the power supply slide 100, the current collector 200 and the lead-out cable 300 are electrically connected in sequence to perform power supply operations between the power supply source and the power-consuming equipment, accompanied by the power-consuming equipment In order to meet the needs of mobile operation of the equipment, the collector 200 moves on the power supply slide line 100 and always maintains electrical connection to ensure the continuous and stable production operation of the blast furnace. In complex operating conditions, when electrical corrosion, jamming, etc. occur on the power supply slide line 100, one of the collectors 200 has an unstable connection, and the other collectors 200 can still stably perform power supply connection operations through the lead-out cable 300, and the spaced collectors 200 maintain a certain distance for power receiving operations, providing a spacing distance for the virtual contacts of the power supply slide line 100, so that even if electrical corrosion, jamming, etc. occur that affect power receiving, normal power receiving operations can still be carried out without stopping, ensuring continuous production of blast furnace feeding, reducing maintenance costs, and improving reliability.

[0033] In an optional embodiment, the connecting frame includes support arms 401 connected to the current collectors 200 , and the number of the support arms 401 is the same as the number of the current collectors 200 .

[0034] By setting the same number of arms 401 as the number of collectors 200, each collector 200 is connected individually, and through the connection between the arms 401, when operating the arms 401, the spacing between the collectors 200 is controlled to be adjusted, so that the collectors 200 are adjusted to the target spacing according to the working requirements and move synchronously.

[0035] In an optional embodiment, a connecting plate 402 is provided at one end of the support arm 401 close to the current collector 200, and the connecting plate 402 is hinged to the support arm 401. During the actual arrangement, the arrangement of the connecting plate 402 improves the operability of the support arm 401 when connecting the current collector 200, and the intersection relationship between the connecting plate 402 and the support arm 401 allows the connecting plate 402 and the support arm 401 to rotate relative to each other. When the current collector 200 is displaced, the support arm 401 and the connecting plate 402 maintain the connection stability of the support arm 401 and the connection stability between the connecting plate 402 and the current collector 200 through relative rotation.

[0036] In an optional embodiment, the connecting plate 402 is detachably connected to the current collector 200. The detachable operation of the connecting plate 402 greatly improves the convenience of operation, maintains the reliability of the electrical connection of the current collector 200, and completes the connection state conversion of the support arm 401 through the disassembly operation of the connecting plate 402, which facilitates rapid disassembly and assembly during continuous operation.

[0037] In an optional embodiment, the support arms 401 are rotatably connected to each other, and under different working conditions, the support arms 401 can be adjusted to different openings, thereby restricting different current collectors 200 to different positions, thereby facilitating the control of the distance between the current collectors 200.

[0038] In an optional embodiment, an adjusting rod passes through the support arm 401, and a nut for limiting the position of the adjusting rod is threadedly connected to the adjusting rod. During specific operation, the opening of the support arm 401 is constrained by adjusting the position of the nut on the adjusting rod, and a stable relative position relationship is obtained by the threaded connection between the adjusting nut and the adjusting rod. Correspondingly, a nut is provided on both sides of each support arm 401 for position constraint.

[0039] In an optional embodiment, an operating block 403 is provided at the connection between the support arms 401 , and the operating block 403 is blocked at the connection between the support arms 401 to facilitate connection and overall operation, thereby reducing the difficulty of moving the collector 200 .

[0040] In an optional embodiment, the connection frame is insulated from the current collector 200 , and the connection frame maintains an insulated state with the current collector 200 , thereby protecting the current collector 200 from relative wear and avoiding electrical conduction.

[0041] In an optional embodiment, two current collectors 200 are provided, and the two current collectors 200 are arranged at an interval so that when one of the current collectors 200 cannot be electrically connected normally, the other current collector 200 can provide a stable connection state to ensure normal processing operations.
