Description

Technical Field

[0001] The utility model relates to a protective cap for preventing misoperation of protective connecting pieces. Background Art

[0002] The protection functions and outputs within the hydropower station's relay protection panels are controlled by a protective chain. During maintenance, these important function and output plates require secondary safety measures to be disabled. During maintenance and commissioning, operations and maintenance personnel can mistakenly re-enable these disabled protection function and output plates, potentially leading to unsafe events such as false alarms and tripping of the protective equipment. Therefore, the protective chain must be protected against false activation.

[0003] Corresponding technical solutions have also been proposed in existing patents, such as patents "CN214255072U; A protective cover to prevent relay protection pressure plate from malfunctioning", "CN207967746U; A protective cover to prevent relay protection pressure plate from malfunctioning and accidentally touching", "CN 206323011U; A protective cover to prevent relay protection pressure plate from malfunctioning and accidentally touching", "CN219394028U; A protective cover to prevent relay protection pressure plate from malfunctioning" and "CN219394405U, A protective cover to prevent relay protection pressure plate from malfunctioning", etc. These technical solutions all place the entire protective link in a closed box. Although they can achieve a good anti-malfunction effect, the protective link needs to be completely removed before the box can be installed on the disk protection cabinet, so the installation is relatively troublesome. In addition, some boxes are mostly made of transparent acrylic, so that the status of the protective link can be intuitively observed. However, after a long time, the box will turn yellow, which not only affects the observation of the link status but also looks unsightly. Utility Model Content

[0004] The purpose of the utility model is to provide a protective cap to prevent misoperation of the protective piece, which replaces the existing protective cover of misoperation with a protective cap, thereby solving the problem that the misoperation protective cover is troublesome to install and becomes yellow after long-term use, affecting observation and appearance.

[0005] In order to solve the above problems, the technical solution of the utility model is:

[0006] A protective cap for preventing misoperation of a protective connecting piece comprises an insulating protective tube inserted on a terminal of the protective connecting piece, a fixing part is provided on the protective tube, an insulating pipe cap is fixedly connected to the pipe opening of the protective tube, and a pulling ring extends outward from the pipe cap.

[0007] A notch is provided at the end of the protective tube away from the tube cap, and the protective connecting bottom plate is arranged in the notch. The fixed part includes a fixed block fixedly connected to the tube end of the protective tube, and a magnet is arranged in the fixed block.

[0008] The fixing part comprises a hose fixedly connected in the protective tube, the hose is provided with a chamfer at one end facing the notch, and the protective connecting terminal knob is inserted into the hose.

[0009] An information plate is connected to the pull ring.

[0010] A QR code label is affixed to the information board.

[0011] The beneficial effects of the present invention are as follows: when the protective link needs to be "prevented from misoperation", it is only necessary to insert the protective cap into the protective link terminal, which is simple to operate and does not require any changes to the existing protective link. In addition, compared with the existing protective cover, the protective cap is compact and easy to carry, and there is no need to worry about the protective cap turning yellow. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 4 It is a schematic diagram of the three-dimensional structure of the utility model.

[0017] In the figure: the panel of the protective cabinet 1, the terminal knob 2, the fixing block 3, the information plate 4, the pipe cap 5, the protective tube 6, the connecting piece 7, the hose 8, the magnet 9, the QR code label 10, the pull ring 11, and the notch 12. DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figures 1 to 3As shown, a protective cap for preventing misoperation of a protective link comprises an insulating protective tube 6 inserted into the terminal of the protective link. The protective tube 6 is made of PVC material and is provided with a fixing portion for fixing the protective tube 6 to the terminal so that it is not easy to fall off the terminal. An insulating cap 5 is bonded to the mouth of the protective tube 6, and a pulling ring 11 extends outward from the cap 5. The pulling ring 11 can firstly facilitate the staff to pull out the protective cap, and secondly, multiple protective caps can be strung together with a rope through the pulling ring 11 for easy storage and carrying. When the protective link needs to be operated to prevent misoperation, such as Figure 1 and 4 As shown, the worker can hold the pull ring 11 and directly insert the protective cap onto the protective connecting terminal to isolate the connecting piece from the terminal.

[0020] In order to prevent the protective cap from falling off the terminal, the utility model is designed with two fixing parts;

[0021] The first type: A notch 12 is provided at the end of the protective tube 6 away from the tube cap 5. The protective connecting plate bottom plate is positioned within the notch 12. The fixing portion includes a fixing block 3 fixedly connected to the end of the protective tube 6. A neodymium iron boron magnet 9 is positioned within the fixing block 3. After the protective cap is attached to the protective connecting terminal, the magnet 9 is attracted to the panel 1 of the protective cabinet to secure the cap and prevent it from falling off the terminal.

[0022] The second type: The fixing portion comprises a silicone rubber hose 8 bonded to the protective tube 6. The hose 8 has a chamfered end facing the notch 12, and the terminal knob for the protective lug is inserted into the hose 8. After the protective cap is put over the terminal, the terminal knob is squeezed into the hose 8 under the guidance of the chamfer, thereby fixing the protective cap and preventing it from falling off the terminal.

[0023] An information plate 4 is connected to the pull ring 11. The information plate 4 records operator information, such as name.

[0024] A QR code label 10 is attached to the information board 4. Information pre-stored on the server allows staff to scan the QR code label 10 with their mobile phone to obtain pre-stored information, such as the operator's phone number, the reason for the protective layer preventing malfunction, and operating instructions. The principle behind this is described in patent "CN205176846U, A Product Information Query System Based on QR Code Technology." This allows for more information to be obtained than simply writing information on the information board 4.

[0025] The contents described in the embodiments of this specification are merely an enumeration of the implementation forms of the utility model concept. The protection scope of the utility model should not be regarded as limited to the specific forms described in the embodiments. The protection scope of the utility model also extends to equivalent technical means that can be thought of by those skilled in the art based on the concept of the utility model.
