Description

Technical Field

[0001] The invention belongs to the technical field of substation operation and maintenance, and in particular relates to a small animal prevention device for a flood prevention hole of a substation. Background Art

[0002] As a key area in the power system, the importance of substations is self-evident. It is not only the core node for power transmission and distribution, but also directly related to the stable operation of the power grid and the quality of power supply. Once the cables are damaged, the connected loads will also have problems. Therefore, ensuring safe operation in substations is the primary task of substation operation and maintenance.

[0003] In substation operation and maintenance, small animal prevention is a key project that cannot be ignored. This work runs throughout the year. Since the activity patterns of small animals are affected by seasonal changes, small animal prevention also needs to be adjusted accordingly according to seasonal changes.

[0004] Judging from the actual cases in recent years, the harm caused by small animals cannot be ignored. They may bite through the optical cable, causing communication interruption and causing trouble for the normal operation of the substation. More seriously, small animals may also enter the electrical equipment, causing the circuit breaker to trip or the equipment to be damaged, posing a serious threat to the safe and stable operation of the power grid.

[0005] In order to better prevent small animals from invading substations, we need to continuously explore and innovate methods and measures to prevent small animals. At present, the flood control holes in the substation walls are directly connected to the environment outside the station, which provides a channel for small animals to enter the substation.

[0006] However, the traditional installation method requires drilling holes in the wall to install expansion screws and fix the protective net on the expansion screws. This method is cumbersome to operate, inconvenient to replace, time-consuming and labor-intensive, and takes up a lot of manpower and material resources. This not only increases the workload of operation and maintenance personnel, but may also lead to uneven installation quality and affect the protection effect.

[0007] Therefore, in order to solve the above problems, it is necessary to design a more convenient and efficient method and measure to prevent small animals. By improving the installation method, efficiency and quality, the substation can be better protected from the harm of small animals and the safe and stable operation of the power grid can be ensured. Summary of the invention

[0008] The technical problem to be solved by the present invention is to solve the deficiencies in the prior art and to design a new device for preventing small animals from entering flood control holes in substations.

[0108] like Figure 1-Figure 12The present invention proposes a device for preventing small animals from entering the substation flood control hole, comprising a protective plate 1 and an adjusting device 2. The protective plate 1 is used to prevent small animals from entering the substation, and the adjusting device 2 is used to adjust the position and height of the support plate 2-3-3-1 to adapt to flood control holes of different specifications, thereby increasing the flexibility of the device of the present invention. The versatility and practicality of the device are greatly enhanced, and a suitable installation position can be found for both newly built and renovated flood control holes to ensure maximum protection effect.

[0109] Embodiment 1:

[0110] like Figure 2 , Figure 5 and Figure 7 As shown, the protective plate 1 adopts a mesh structure, with a solid body in the middle for fixing the adjustment device 2, and the rest is a mesh structure, which prevents small animals from entering the substation without destroying the drainage function of the flood control tunnel itself.

[0111] like Figure 1-Figure 7 As shown, the adjusting device 2 is fixed on the side of the protective plate 1; the protective plate 1 is vertically arranged and aligned with the position of the flood control tunnel, and the adjusting device 2 is horizontally arranged and adjusted according to the size of the on-site flood control tunnel, so that the adjusting device 2 is close to the upper and lower ends of the flood control tunnel, and is pressed against the upper and lower side walls of the flood control tunnel to firmly install the protective plate 1 in the flood control tunnel; the protective plate 1 is also closely attached to the surface of the wall to prevent small animals from entering the substation from the flood control hole.

[0112] like Figure 1 As shown, the adjusting device 2 includes an adjusting handle 2-1, an adjusting shaft 2-2, a first adjusting rod 2-3 and a second adjusting rod 2-4. The adjusting handle 2-1 is used to control the rotation of the adjusting shaft 2-2. The rotation of the adjusting shaft 2-2 drives the first adjusting rod 2-3 and the second adjusting rod 2-4 in contact therewith to move and transform, thereby achieving the purpose of the adjusting device 2 adapting to flood control tunnels of different sizes. The operation is simple and easy to learn, and the use is simple and convenient. The staff can adjust it at will according to the actual situation on site.

[0113] like Figure 1 and Figure 8 As shown, the adjustment shaft 2-2 passes through the protective plate 1 and extends into the first connection hole 2-1-1 set in the adjustment handle 2-1. The protective plate 1 passes through the adjustment shaft 2-2 and is fixed, so that the positions of the two are relatively fixed, ensuring the stability of the structure of the device of the present invention and preventing the device from falling apart during use. The adjustment shaft 2-2 is connected to the adjustment handle 2-1. The rotation of the adjustment handle 2-1 drives the adjustment shaft 2-2 to rotate, and the adjustment shaft 2-2 drives the adjustment rod to rotate, thereby realizing the adjustment function of the adjustment device 2.

[0114] like Figure 3As shown, the first adjustment rod 2-3 and the second adjustment rod 2-4 are fixed to the side of the protective plate 1, and are fixed from both the upper and lower sides to ensure that the upper and lower ends of the device are close to the wall, ensuring the stability of the device after being fixed to prevent it from collapsing due to impact by small animals or other objects.

[0115] An adjusting tube 2-5 is arranged between the first adjusting rod 2-3 and the second adjusting rod 2-4. The fixed positions of the free ends of the first adjusting rod 2-3 and the second adjusting rod 2-4 are adjusted through the relative action between the adjusting tube 2-5 and the adjusting shaft 2-2, so that the device can adapt to different sizes, thereby greatly improving the versatility and practicality of the device.

[0116] The adjusting tube 2-5 is provided with a threaded hole 2-5-1, and the adjusting shaft 2-2 is provided with a threaded shaft 2-2-1 and a fixed shaft 2-2-2. The adjusting tube 2-5 and the threaded shaft 2-2-1 are threadedly connected, and the threaded connection realizes the relative action between the two. The position of the adjusting tube 2-5 on the threaded shaft 2-2-1 is adjusted to drive the first adjusting rod 2-3 and the second adjusting rod 2-4 to move along the adjusting shaft 2-2.

[0117] The fixed shaft 2-2-2 is fixed in the first connecting hole 2-1-1, so that the rotation of the adjustment handle 2-1 drives the rotation of the adjustment shaft 2-2.

[0118] The fixed shaft 2-2-2 can be rectangular, triangular, etc. In the present embodiment, the fixed shaft 2-2-2 is preferably rectangular, and correspondingly, the first connecting hole 2-1-1 is also rectangular, so that when the rotary handle and the adjusting shaft 2-2 are rotated, it is more difficult for the adjusting shaft 2-2 to rotate when subjected to external force. This means that the adjusting handle 2-1 can more effectively drive the adjusting shaft 2-2 to rotate when rotating, without losing energy or generating unnecessary friction due to rotation.

[0119] At the same time, the rectangular shape enables the fixed shaft 2-2-2 to better resist deformation when subjected to torsional force, which helps to maintain the precise transmission relationship between the adjustment handle 2-1 and the adjustment shaft 2-2, ensuring the accuracy and reliability of the rotation.

[0120] The first adjusting rod 2-3 and the second adjusting rod 2-4 have the same structure and are respectively arranged on the upper and lower sides of the adjusting shaft 2-2, so that the upper and lower sides of the device of the present invention have supporting forces so that the protective plate 1 of the device is vertically placed in the control hole.

[0121] The first adjustment rod 2-3 includes a main adjustment rod 2-3-1 and a slave adjustment rod 2-3-2. The main adjustment rod 2-3-1 and the slave adjustment rod 2-3-2 are connected through a support device 2-3-3. The main adjustment rod 2-3-1 connects the protective plate 1 and the support device 2-3-3, and the slave adjustment rod 2-3-2 connects the support device 2-3-3 and the adjustment tube 2-5. One end of the main adjustment rod 2-3-1 is fixed to the side of the protective plate 1 and cannot be moved, but can be rotated; the other end is connected to the support device 2-3-3 and can move. One end of the slave adjustment shaft 2-2 is connected to the support device 2-3-3, and the other end is connected to the adjustment tube 2-5.

[0122] During specific use, the staff holds the adjusting handle 2-1 and rotates it, driving the adjusting shaft 2-2 to rotate. The adjusting shaft 2-2 and the adjusting tube 2-5 are threadedly connected, so that the adjusting tube 2-5 moves left and right along the adjusting shaft 2-2, driving the end of the adjusting tube 2-5 that contacts the adjusting shaft 2-2 to move left and right along the adjusting shaft 2-2, so that the supporting device 2-3-3 moves up and down in a direction perpendicular to the adjusting shaft 2-2, so that it can adapt to flood control tunnels of different heights.

[0123] Embodiment 2:

[0124] On the basis of Example 1, the position of the support device 2-3-3 is limited to achieve the support function while ensuring the simplicity of the structure.

[0125] The side of the support plate 2-3-3-1 is provided with a second connecting ear 2-3-3-2, and the main adjusting rod 2-3-1 and the slave adjusting rod 2-3-2 are fixed to the side of the connecting ear by the second bolt 2-3-3-3 and the second nut 2-3-3-4. The support plate 2-3-3-1 and the adjusting rod are connected by the second bolt 2-3-3-3 and the second connecting ear 2-3-3-2, and the second bolt 2-3-3-3 passes through the second connecting ear 2-3-3-2 and the adjusting rod and is fixed by the second nut 2-3-3-4 to prevent the second bolt 2-3-3-3 from falling off and the device from falling apart.

[0126] In this embodiment, three second connecting ears 2-3-3-2 are provided, and one gap between the two is used to place the main adjusting rod 2-3-1, and the other gap is used to place the slave adjusting rod 2-3-2.

The fixing plate 2-2-4 is used to limit the lubricating sleeve 2-2-3, and both ends of the lubricating sleeve 2-2-3 are limited by the fixing plate 2-2-4 and the adjusting handle 2-1 to prevent the lubricating sleeve 2-2-3 from shifting.

[0129] The fixing plate 2-2-4 is fixed to the side of the lubricating sleeve 2-2-3 to fix the position of the lubricating sleeve 2-2-3. The surface of the lubricating sleeve 2-2-3 contacts the protective plate 1. The adjusting shaft 2-2 and the protective plate 1 are buffered by the lubricating sleeve 2-2-3 to prevent direct contact between the two and wear caused during rotation. The service life of the device of the present invention is improved.

[0130] In this embodiment, the lubricating sleeve 2-2-3 is specifically a flange sleeve, which prevents the adjusting shaft 2-2 and the protective plate 1 from rotating relative to each other for a long time, causing wear of both.

[0131] Embodiment 4:

[0132] like Fig. 9 As shown, based on Example 1, a limit block 2-2-5 is provided on the side of the adjusting shaft 2-2 away from the fixed shaft 2-2-2 to prevent the adjusting handle 2-1 from rotating excessively and causing the first adjusting rod 2-3 and the second adjusting rod 2-4 to be adjusted away from the adjusting shaft 2-2.

[0133] Embodiment 5:

[0134] On the basis of the early embodiment 1, the connection structure between the limiting adjustment rod and the protective plate 1 is selected to be fixed with connecting ears and bolts, so that the main adjustment rod 2-3-1 can rotate along the bolts to realize the adjustment function of the adjustment member.

[0140] Embodiment 7:

[0141] On the basis of Example 1, the fixed shaft 2-2-2 and the adjusting handle 2-1 are fixed by a second screw rod 2-1-2, so as to further strengthen the connection between the adjusting shaft 2-2 and the adjusting handle.

[0142] The second screw 2-1-2 passes through the third connection hole set in the adjusting handle 2-1 and the fourth connection hole set in the fixed shaft 2-2-2. The second screw 2-1-2 can be directly passed through the adjusting handle 2-1 and the fixed shaft 2-2-2 to prevent the adjusting shaft 2-2 from falling out of the adjusting handle 2-1.

[0143] Embodiment 8:
