Description

Technical Field

[0001] The utility model relates to the field of auxiliary tools for the maintenance of power distribution equipment, in particular to a preventive safety operation and maintenance device for power distribution equipment. Background Technique

[0002] When maintaining and inspecting power distribution equipment, power on and off operations are required. Currently, when powering on the power distribution equipment after maintenance or inspection, generally two people are needed for the operation. One staff member holds the power-on rod to push the switch control rod, and the other staff member holds the evacuation rod to hook the staff member holding the power-on rod. If there is an explosion problem with the power distribution equipment, the mutual cooperation of the two people can reduce the probability of the staff being electrocuted. However, even with the mutual cooperation of the two people, there is still a risk of being electrocuted. The explosion of the power distribution equipment generally occurs instantaneously, and it is difficult for the staff to react. If the reaction speed is slow, it is difficult to withdraw to the safe area. If not withdrawn to the safe area, it is easy to be electrocuted. Therefore, the utility model provides a preventive safety operation and maintenance device for power distribution equipment to solve the above-mentioned problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a preventive safety operation and maintenance device for power distribution equipment to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A preventive safety operation and maintenance device for power distribution equipment includes an installation shell. The lower end of the installation shell is fixedly connected with a bottom shell. The upper end of the bottom shell is detachably connected with a driving member. The output end of the driving member is connected with a power assembly. A connecting structure for pulling the switch is wound inside the power assembly, and the connecting structure passes through the bottom shell. In order to facilitate the connection between the installation shell and the power distribution equipment, a magnet block is fixedly connected to the outer wall of the installation shell;

[0006] The power assembly includes a driving gear. A driven gear is meshed with the side end of the driving gear. The driven gear is connected to the inside of the installation shell through a fixing rod, and the fixing rod is rotationally connected to the installation shell in a damped manner. The driven gear is fixedly connected to the fixing rod. A wire reel is connected to the outside of the fixing rod through a one-way bearing, that is, the wire reel can rotate unidirectionally on the fixing rod.

[0007] As a further scheme of the utility model, the connecting structure includes a main rope. The main rope is wound around the outside of the wire reel. The lower end of the main rope is fixedly connected with a main connecting rope. One end of the main connecting rope away from the main rope is detachably connected with a secondary connecting rope. An adjusting column is sleeved between the secondary connecting rope and the main connecting rope.

[0008] As a further solution of the present utility model, a threaded sleeve is fixedly connected to one end of the main connecting rope away from the main rope, a threaded head is fixedly connected to one end of the auxiliary connecting rope close to the main connecting rope, and the threaded head is threadedly connected to the inside of the threaded sleeve.

[0009] As a further solution of the present utility model, both the main rope and the auxiliary connecting rope pass through the adjusting column and are slidably connected to the adjusting column.

[0010] As a further solution of the present utility model, a threaded cap is threadedly connected to the outside of the adjusting column, the main rope passes through the threaded cap, and the auxiliary connecting rope is fixedly connected to the threaded cap.

[0011] As a further solution of the present utility model, in order to ensure that the connection structure can be applied to a smaller switch control rod, a rubber sleeve is fixedly connected to the inside of the adjusting column, the main rope passes through the rubber sleeve, and the inner diameter of the rubber sleeve is smaller than the outer diameter of the main rope. In this way, the friction between the main rope and the adjusting column can be increased.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] 1. When the present utility model is used, the connection structure is connected to the switch control rod, and then withdrawn to the safe area. Then, the driving member is remotely activated to drive the winding wheel to rotate, so that the connection structure rises to pull the switch control rod to close and complete the power-on of the equipment. In this way, the safety of operating on the power distribution equipment can be greatly increased.

[0014] 2. When the present utility model is used, if there is a short circuit problem inside the power distribution equipment, the switch control rod will automatically bounce back. When the switch control rod automatically bounces back, it will pull the connection structure. At this time, the take-up wheel will rotate idly and release the wire due to the one-way bearing, so as to avoid the connection structure blocking the automatic bounce-back of the switch control rod. In this way, the staff can be protected from electric shock. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 5 , in the embodiment of the present invention, a preventive safety operation and maintenance device for a power distribution device includes an installation shell 1. A bottom shell 3 is fixedly connected to the lower end of the installation shell 1. The upper end of the bottom shell 3 is detachably connected to a driving part 5 by screws. The output end of the driving part 5 is connected to a power assembly 6. A connection structure 9 for pulling a switch is wound inside the power assembly 6, and the connection structure 9 passes through the bottom shell 3. Specifically, the driving part 5 is a motor. A connection window 4 is opened at the upper end of the bottom shell 3, and the connection structure 9 passes through the bottom shell 3 through the connection window 4. In order to facilitate the connection between the installation shell 1 and the power distribution device, a magnet block 2 is fixedly connected to the outer wall of the installation shell 1. A control main board 7 is also fixedly connected inside the installation shell 1. A remote communication chip is installed inside the control main board 7. The remote communication chip is prior art and will not be described in detail here. Through the remote communication chip, the driving part 5 can be remotely operated, thereby increasing the safety of the present invention. A battery 8 is also installed inside the installation shell 1;

[0025] The power assembly 6 includes a driving gear 500 fixedly mounted on the output shaft of the driving member 5. A driven gear 603 is meshed with the side end of the driving gear 500. The driven gear 603 is connected to the inside of the mounting shell 1 through a fixing rod 601, and the fixing rod 601 is rotationally connected to the mounting shell 1 in a damping manner. The driven gear 603 is fixedly connected to the fixing rod 601. A wire reel 600 is connected to the outside of the fixing rod 601 through a one-way bearing 602, that is, the wire reel 600 can rotate unidirectionally on the fixing rod 601;

[0026] The connecting structure 9 includes a main rope 900 wound around the outside of the wire reel 600. Specifically, the outer diameter of the driving gear 500 is smaller than that of the driven gear 603. In this way, the torque of the fixing rod 601 can be increased, and thus it is convenient for the wire reel 600 to wind the connecting structure 9. The lower end of the main rope 900 is fixedly connected to a main connecting rope 901. One end of the main connecting rope 901 away from the main rope 900 is detachably connected to a sub-connecting rope 910. An adjusting column 904 is sleeved between the sub-connecting rope 910 and the main connecting rope 901. Specifically, one end of the main connecting rope 901 away from the main rope 900 is fixedly connected to a threaded sleeve 902, and one end of the sub-connecting rope 910 close to the main connecting rope 901 is fixedly connected to a threaded head 903. The threaded head 903 is threadedly connected to the inside of the threaded sleeve 902. By separating the main connecting rope 901 and the sub-connecting rope 910, the connecting structure 9 can be connected to the closed switch control rod (for details, please refer to Figure 5 , and for more specific reference Figure 5 at A in);

[0027] Both the main rope 900 and the sub-connecting rope 910 pass through the adjusting column 904 and are slidably connected to the adjusting column 904. Specifically, a threaded cap 905 is threadedly connected to the outside of the adjusting column 904. The main rope 900 passes through the threaded cap 905, and the sub-connecting rope 910 is fixedly connected to the threaded cap 905. A through hole 906 for the main rope 900 to pass through is opened at the upper end of the threaded cap 905. More specifically, a connecting channel 908 and an adjusting channel 909 are opened inside the adjusting column 904. The main rope 900 passes through the adjusting column 904 through the connecting channel 908, and the sub-connecting rope 910 passes through the adjusting column 904 through the adjusting channel 909. By rotating the threaded cap 905 upward, the sub-connecting rope 910 can be driven to move upward, thereby reducing the inner diameter of the loop formed between the main connecting rope 901 and the sub-connecting rope 910. Thus, the connecting structure 9 can be connected to the open switch control rod through the main connecting rope 901 and the sub-connecting rope 910 (for details, please refer to Figure 5 , and for more specific reference Figure 5 at B in);

[0028] To ensure that the connection structure 9 can be applied to the internal fixing of a smaller switch control lever adjusting column 904, a rubber sleeve 907 is fixedly connected inside. The rubber sleeve 907 is located within the connection channel 908. The main rope 900 passes through the rubber sleeve 907, and the inner diameter of the rubber sleeve 907 is smaller than the outer diameter of the main rope 900. In this way, the friction between the main rope 900 and the adjusting column 904 can be increased, so that when the staff pulls up the main rope 900, the inner diameter of the formed loop between the main connection rope 901 and the secondary connection rope 910 can also be controlled.

[0029] The working principle of the present utility model is as follows:

[0030] When the present utility model is in use, before closing the switch control lever to connect the power distribution equipment, first adsorb the mounting shell 1 on the surface of the power distribution equipment, then put the main connection rope 901 and the secondary connection rope 910 on the rod wall of the switch control lever, and then rotate the threaded cap 905 to reduce the loop formed by the main connection rope 901 and the secondary connection rope 910, so that the connection structure 9 is connected to the switch control lever. Then, after the staff withdraws to the safe area, it is remotely controlled to turn on the driving member 5. After the driving member 5 is turned on, it will drive the driven gear 603 to rotate through the driving gear 500 (at this time, the one-way bearing 602 is in a locked state, that is, the wire reel 600 will rotate together with the fixed rod 601 and the driven gear 603), thereby driving the wire reel 600 to rotate. When the wire reel 600 rotates, it will pull the main rope 900, thus driving the switch control lever to close. When the switch control lever is closed, the staff immediately turns off the driving member 5. At this time, if there is a short circuit problem inside the power distribution equipment, the switch control lever will automatically rebound (the automatic rebound of the switch control lever belongs to the prior art). When the switch control lever automatically rebounds, it will pull the connection structure 9. At this time, the wire reel 600 will idle and release the wire due to the one-way bearing 602, thus preventing the connection structure 9 from blocking the automatic rebound of the switch control lever, protecting the staff in this way to avoid the problem of electric shock.

[0031] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
