Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power transformation station safety protection, and particularly relates to an animal blocking device for a power transformation station. BACKGROUND

[0002] With the expansion of urban construction and the continuous improvement of ecological environment, animal activities around the power transformation station are more and more frequent, and small animals such as weasels and cats have become an important factor threatening the safety of the power transformation station. When the existing measures are not sufficient, small animals can enter the station by climbing the fence, stand and the like, and frequent power outages caused by their invasion will not only affect the stability of power supply, causing economic losses to industrial production and commercial operation, but also interfere with the normal life of residents, and adversely affect the normal operation of society.

[0003] Based on this, the invention with the announcement number CN116267882B discloses a new type of power transformation station small animal prevention thorn, which is applied to a power transformation station and includes a middle steel plate, upper triangular teeth and lower triangular teeth: the middle steel plate is installed on the outer surface of the wall of the power transformation station near the upper end position; the number of the upper triangular teeth is several groups, and one end of the upper triangular teeth is detachably connected with the side surface of the middle steel plate; the number of the lower triangular teeth is several groups, and one end of the lower triangular teeth is detachably connected with the other side surface of the middle steel plate; wherein, the upper triangular teeth and the lower triangular teeth are arranged at equal intervals.

[0004] The application effectively prevents small animals from climbing the wall to enter the power transformation station and prevents people with ulterior motives from entering the power transformation station to threaten the power grid, has good protection effect and good use prospect. However, the following problems still exist in specific use: Firstly, the protection mode is single, and the device only relies on the single principle of "physical thorn deterrence" without integrating other protection means: there is no design to cope with the invasion mode of "jumping across" (such as small animals such as weasels and cats jumping from above the device); the logic of "deterrence + blocking" is not considered, and only the sharp teeth form a block; secondly, the installation scene is limited, and the device is fixed on the surface of the fence by steel nails, which is only suitable for solid fences, and has poor adaptability to the structures of metal fences and net-shaped fences commonly used in power transformation stations, and cannot be directly installed.

[0005] Therefore, there is an urgent need for an animal blocking device for a power transformation station with diverse protection modes and wide application range to solve the above technical problems. SUMMARY

[0006] The purpose of the present application is to provide an animal blocking device for a power transformation station, which can provide behavior deterrence and physical blocking for animals, improve the protection effect in all directions, and meet the use of various fence structures of the power transformation station, and has wide application range.

[0007] The present invention adopts the following technical solution: A substation animal barrier device includes a protective body, which includes a lower vertical support section and an arc-shaped shielding section at the top of the vertical support section. Multiple rows of deflector plates are spaced apart from top to bottom on the protective body. Each deflector plate has a spike at one end away from the protective body, and the spike is arranged along the length of the deflector plate.

[0008] Preferably, the vertical support section and the arc-shaped shielding section on the protective body are integrally formed.

[0009] Preferably, the inner wall of the protective body is smooth.

[0010] Preferably, each of the said expulsion plates is inclined downwards.

[0011] Preferably, the tilt angle of the expulsion plate is 40° to 50°.

[0012] Preferably, the expulsion plate is disposed on the vertical support section.

[0013] Preferably, the expulsion plate is detachably connected to the vertical support section.

[0014] Preferably, a plurality of mounting seats are provided at intervals on the vertical support section, and the mounting seats include baffles at both ends, and the expulsion plate is mounted between two of the baffles by bolts.

[0015] Preferably, a connecting plate is provided on the rear side of the two baffles, the connecting plate is fixedly connected to the protective body, and a positioning hole is provided through the connecting plate and the corresponding protective body; a support plate is provided at the bottom of the two baffles; when the expulsion plate is connected to the baffle, the back of the expulsion plate contacts the connecting plate and the support plate.

[0016] Preferably, the tip of the spike has an arc-shaped structure.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting the upper part of the protective body to an arc-shaped structure, the present invention can fundamentally eliminate the point of force required for animals to climb upwards by utilizing the streamlined structure of the inner arc; through the coordinated arrangement of multiple rows of expulsion plates with spikes, a dual protection logic of "physical blocking + behavioral deterrence" can be constructed, which comprehensively improves the blocking effect and thus ensures the safety of the substation.

Detailed Implementation

[0019] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments: like Figures 1 to 5 As shown, the substation animal barrier device of the present invention includes a protective body 1. The protective body 1 includes a lower vertical support section 1-1 and an arc-shaped shielding section 1-2 at the top of the vertical support section 1-1. The vertical support section 1-1 and the arc-shaped shielding section 1-2 are preferably integrally formed. The specific material can be high-strength stainless steel or hot-dip galvanized steel. It is processed by an integral bending forming process, which can ensure the smoothness of the inner surface of the protective body 1, especially the smoothness of the arc-shaped shielding section 1-2, so as to ensure the structural strength and avoid the rough surface providing an indirect support point for animals.

[0020] In this invention, the arc-shaped shielding section 1-2 extends clockwise from the top of the vertical support section 1-1, forming an arc-shaped structure with an upward convex and inward concave shape at the front of the protective body 1. Multiple rows of deflector plates 2 are spaced apart from top to bottom on the protective body 1. The deflector plates 2 are preferably located on the vertical support section 1-1. Each deflector plate 2 has a spike 3 at its end away from the protective body 1, and the spikes 3 are spaced apart along the length of the deflector plate 2. By setting the arc-shaped shielding section 1-2 at the top of the protective body 1, this invention can utilize the streamlined, inward-curving structure to fundamentally eliminate the point of leverage required for animals to climb upwards. Because small animals such as weasels and cats rely on the mechanical logic of "limb gripping + body leverage" when climbing, they need to find protrusions, edges, or planes on the contact surface as support points, generating upward friction through stepping and wrapping. The inner arc-shaped top has no flat, right-angled, or protruding structures; its smooth, continuous surface prevents animals from forming an effective grip with their limbs, and makes it difficult for them to secure their bodies by wrapping around it. This causes climbing to be interrupted due to a lack of leverage, thus achieving the purpose of physical obstruction. In addition, the spikes 3 on the deterrent plate 2 can cause animals pain when they jump and come into contact with it, creating a psychological deterrent and achieving the purpose of multi-directional protection, reducing the probability of animals entering the substation.

[0021] Furthermore, each deflector plate 2 is inclined downwards, preferably at an angle of 40° to 50°. This angle is the angle between the lower part of the deflector plate 2 and the vertical support section 1-1 of the protective body 1. At an inclination angle of 40°-50°, the contact surface between the deflector plate 2 and the vertical support section 1-1 is too steep, making it impossible for animal claws to find a stable point of force and climb upwards, thus directly cutting off the path of "climbing and invading along the protective body 1". In addition, even if a small animal attempts to jump from below or to the side of the protective body 1, the spikes 3 will directly block its predetermined landing point. The small animal cannot land stably on the inclined spikes 3, and the inclination direction will disrupt its jumping balance, avoiding the intrusion situation of "leaping over the device", thus making up for the deficiency of the existing device's insufficient anti-jump capability. The length of the spikes 3 is ≥5cm, and the spacing is ≤3cm; to provide a sufficient deterrent distance and ensure the isolation effect.

[0022] Furthermore, the expulsion plate 2 is detachably connected to the vertical support section 1-1 for subsequent targeted replacement and maintenance, reducing maintenance costs. Multiple mounting seats are spaced apart on the vertical support section 1-1. Each mounting seat includes a baffle 4 at both ends. Screw holes are provided on the side walls of both the baffle 4 and the expulsion plate 2. The expulsion plate 2 is bolted between two baffle 4. Additionally, a connecting plate 5 is provided on the rear side of each baffle 4. The connecting plate 5 is fixedly connected to the protective body 1, and the connection between the connecting plate 5 and the protective body 1 can be achieved by welding. Positioning holes 6 are correspondingly provided through the connecting plate 5 and the corresponding protective body 1 for fixing the protective body 1 to the fence with bolts. Support plates 8 are provided at the bottom of each baffle 4. When the expulsion plate 2 is connected to the baffle 4, the back of the expulsion plate 2 contacts the connecting plate 5 and the support plate 8, providing support for the expulsion plate 2 and ensuring its strength under stress.

[0023] Furthermore, in this invention, the end of the spike 3 is preferably arc-shaped. The arc-shaped structure can cause a stinging sensation when an animal jumps and touches it, but it will not pierce its skin and cause significant harm. This serves as a deterrent while reducing the damage to the animal. In addition, ventilation holes 7 can be opened between two adjacent deflector plates 2 in the vertical support section 1-1 of the protective body 1 to guide airflow and reduce the impact of external wind.

[0024] In use, the protective body 1 is first fixedly connected to the fence posts using stainless steel bolts; then, the deflector plate 2 is installed between the two baffles 4 of the mounting base using bolts. By incorporating the arc-shaped shielding section 1-2 at the top of the protective body 1, the invention utilizes an inward-curved streamlined structure to fundamentally eliminate the point of leverage required for animals to climb upwards, thus achieving physical obstruction. Furthermore, the spikes 3 on the deflector plate 2 cause pain to animals upon jumping and contact, creating a psychological deterrent and achieving multi-directional protection, reducing the probability of animals entering the substation.
