Description
Technical Field
[0001] The present invention relates to a device for preventing small animals from climbing on electric poles, belonging to the technical field of power line maintenance. Background Art
[0002] At present, when the overhead lines in the power system are operating normally, it is necessary to prevent small animals such as snakes, mice, and squirrels from climbing onto the live exposed parts such as transformer platforms and pole-mounted switches to ensure the normal and safe operation of the lines. However, in the actual operation process, small animals such as snakes, mice, and squirrels often climb along the electric poles onto the transformer platforms and pole-mounted switches, causing discharge and short-circuit faults of the overhead line equipment, resulting in accidents such as line tripping, power outage, and equipment damage.
[0003] Chinese Patent No. CN115176792A discloses a device for preventing small animals from climbing on power distribution equipment, including a power mechanism, a protective cover, and a support mechanism for installing the protective cover on an electric pole. The power mechanism is fixed at the upper end of the electric pole. The power mechanism includes a solar panel, a battery, a transformer, and an ultrasonic mechanism. The solar panel is electrically connected to the battery, the battery is electrically connected to the transformer, the battery is electrically connected to the ultrasonic mechanism, and the transformer is electrically connected to the support mechanism. The protective cover surrounds the electric pole and is in the shape of a horn with a smaller upper part and a larger lower part. The protective cover of this device surrounds the electric pole and is in the shape of a horn with a smaller upper part and a larger lower part, so the protection against small animal climbing is not sufficient. For small animals such as squirrels, when climbing, they usually use a form of jumping plus climbing, and some small and flexible small animals can still pass through the wire mesh and touch the lines in the transformer, resulting in a short circuit in the transformer and causing a transformer line fault; therefore, the applicable situation of the entire device is insufficient.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to 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 efforts shall fall within the protection scope of the present invention.
[0030] An anti-small animal blocking device for electric poles, the device is installed on the electric poles of power distribution equipment, the device includes a blocking device 1, and the blocking device 1 includes an annular fixing frame 11 and a plurality of support rods 12; the annular fixing frame 11 is wrapped and fixed on the electric pole, and a transmission device is arranged inside the annular fixing frame 11, and the annular fixing frame 11 is rotationally connected to the support rods 12 through the transmission device; an elastic blocking cover 13 is arranged between the support rods 12; a gravity sensor and a plc controller are arranged inside the annular fixing frame 11, and the gravity sensor, the plc controller and the transmission device are electrically connected; after the gravity sensor senses a preset gravity, the plc controller controls the support rods 12 to rotate downward until the gravity is reduced, and then the support rods 12 rotate upward to return to their original state; an anti-escape device 2 is also arranged above the blocking device 1 on the electric pole, and the anti-escape device 2 includes an installation ring 21, and the installation ring 21 is also provided with a transmission device, and the installation ring 21 is rotationally connected with a plurality of rotating rods 22 through the transmission device, and the plurality of rotating rods 22 form an umbrella-shaped structure; a signal receiver is arranged inside the installation ring 21; the signal receiver and the transmission device are electrically connected, and the gravity sensor and the signal receiver are signal-connected to control the opening and closing of the umbrella-shaped structure formed by rotating the plurality of rotating rods 22, and the plurality of rotating rods 22 can rotate downward to cover the upper part of the blocking device 1; a conical thorn structure is arranged inside the rotating rod 22; specifically, the length of the support rod 12 is greater than that of the rotating rod 22, such as Figure 1, in the initial state, the blocking part formed by the elastic blocking cover 13 arranged between the support rods 12 faces upward in a funnel shape. The rotating rod 22 abuts tightly against the utility pole upward. At this time, the cone thorn structure faces outward, which can further prevent animals from climbing; as Figure 2 , when a small animal climbs over the bottom of the elastic blocking cover 13 and jumps onto the annular fixing frame 11, the gravity sensor inside the annular fixing frame 11 reaches the preset threshold, sends a signal to the signal receiver, and controls the transmission device to rotate the rotating rod 22 downward until the bottom of the rotating rod 22 abuts against the elastic blocking cover 13. At this time, the cone thorn structure stabs downward to stimulate the small animal but will not cause it great harm. At the same time, an elastic blocking cover 13 can also be arranged between the rotating rods 22 to form an enclosed space after the bottom of the rotating rod 22 abuts against the elastic blocking cover 13; as Figure 3 , then, the elastic blocking cover 13 arranged between the support rods 12 is rotated downward by the plc controller to form an umbrella-shaped structure, that is, the downward exit is opened. Through the stimulation of the cone thorn structure of the upper rotating rod 22, the small animal is forced to leave. And a vibrator is arranged at the bottom of the elastic blocking cover 13. The vibrator is electrically connected to the gravity sensor. When the downward driving channel is opened, the vibrator starts to accelerate the falling of the small animal until the sensor senses that there is no gravity, and then it returns to the initial state.
[0031] The annular fixing frame 11, the mounting ring 21 and the driving shell 5 are installed in the hollow middle of the utility pole. The overall structural stability can be strengthened by strengthening the structure of the driving shell 5 or by plastic-sealing the outside of the driving shell 5 with cement. It is worth mentioning that the method of strengthening the structure is not limited to the above.
[0032] Furthermore, the transmission device includes electric push rods 3 respectively arranged at the bottom end inside the driving shell 5 at the corresponding positions of the mounting ring 21 and the annular fixing frame 11. The mounting ring 21 and the annular fixing frame 11 are recessed inward to form a number of U-shaped grooves. Bearings 6 are fixed on both sides of the U-shaped grooves. The end of the push rod of the electric push rod 3 is provided with an annular turntable 31, and a number of strip gears 32 are arranged in an array on the annular turntable 31; a number of circular gears 33 are arranged at the bottoms of a number of support rods 12 and a number of rotating rods 22, and the circular gears 33 are fixed on the bearings 6; the strip gears 32 in the two transmission devices are respectively meshed with the support rods 12 and the rotating rods 22 correspondingly; specifically, when the plc controller or the signal receiver is started after receiving a signal, the electric push rod 3 is started, and the annular turntable 31 moves upward or downward following the electric push rod 3. The strip gears 32 arranged on the annular turntable 31 move synchronously. Because the strip gears 32 are meshed with the circular gears 33, when the strip gears 32 move, a number of support rods 12 or a number of rotating rods 22 on the circular gears 33 all swing up and down to achieve the effect of controlling the blocking device 1 and the anti-escape device 2.
[0033] Furthermore, the cone thorn structure includes a rotating rod 22 and a cavity formed inside a circular gear 33 corresponding to the rotating rod 22. A motor 222 is fixedly connected to the inner bottom wall of the cavity of the circular gear 33. The end of the output shaft of the motor 222 is vertically upward and fixedly connected with an incomplete gear 223. An external tooth ring 224 is also provided inside the cavity. The incomplete gear 223 meshes with the external tooth ring 224. A swinging column 225 is arranged on the outer wall of the external tooth ring 224. The swinging column 225 is arranged inside the inner cavity of the rotating rod 22. A number of spikes are arranged on one side of the swinging column 225. A compression spring 226 is arranged on the other side of the swinging column 225. The other end of the compression spring 226 is fixed on the inner wall of the cavity of the rotating rod 22. An opening corresponding to the spikes is arranged on one side of the rotating rod 22. Specifically, after the gravity sensor sends a signal to instruct the motor 222 to start, the incomplete gear 223 is driven to rotate. When it rotates to the point where the incomplete gear 223 meshes with the external tooth ring 224, the swinging column 225 swings in the direction of the rotation of the external tooth ring 224, that is, swings towards the side of the compression spring 226, squeezing the compression spring 226. Then the incomplete gear 223 continues to rotate until it no longer meshes with the external tooth ring 224. Then the swinging column 225 no longer receives the pressure of the compression spring 226 and automatically pops outwards. The spikes can pass through the opening and stab outwards. Repeating the above process can repeatedly retract and pop out the spikes.
[0034] As a preferred solution, a thorn plate 4 is also arranged on the surface of the electric pole at the bottom of the blocking device 1. A steel wire is wound around the thorn plate 4, and a serrated scraper is arranged on the steel wire.
[0035] Furthermore, a number of liquid permeable holes are formed in the support rod 12. A sealing cylinder 121 is arranged inside the support rod 12. A small through hole is arranged on the side wall of the sealing cylinder 121 away from the electric pole. An irritating liquid is arranged inside the sealing cylinder 121. The irritating liquid includes realgar, alcohol or ammonia water. The small through hole on the sealing cylinder 121 only allows the liquid to flow out drop by drop. The irritating liquid occupies two-thirds of the solvent of the sealing cylinder 121. In the initial state, the sealing cylinder 121 is inclined with the small through hole facing upwards to prevent the irritating liquid from flowing out. After the support rod 12 is toppled, the small through hole is inclined downwards, and the irritating liquid inside the sealing cylinder 121 drops drop by drop and then flows to the support rod 12 through the liquid permeable holes, playing a role in driving away small animals.
[0036] Furthermore, a flash lamp is also arranged on the electric pole between the blocking device 1 and the anti-escape device 2. The flash lamp is connected to the gravity sensor and is used to generate a flash to drive away small animals when the gravity sensor detects small animals.
[0037] As a preferred solution, as Figure 8As shown, the rotating rod 22 is made of insulating material, and an electric shock driving structure is arranged on the rotating rod 22. The electric shock driving structure includes a plurality of conductive tension springs arranged on a plurality of rotating rods 22. The conductive tension springs have a certain elasticity and do not affect the movement of the rotating rod 22 to form upper and lower covers. The conductive tension springs are connected to the DC negative electrode and the DC positive electrode at intervals to conduct electricity. When the positive and negative electrodes are touched simultaneously, they are stimulated by current to achieve driving, and at the same time, it can prevent small animals from escaping upwards through the gaps between the swing rods. At the same time, for common animal types in different regions, the distribution density of the conductive tension springs and the electric shock working current can be adjusted.
[0038] Embodiment of the working principle:
[0039] On the surface of the electric pole at the bottom of the blocking device 1, there is also a thorn plate 4. The thorn plate 4 is wound with steel wires, and serrated scrapers are arranged on the steel wires, which can form the first obstacle to small animals; in the initial state, the blocking part formed by the elastic blocking cover 13 arranged between the support rods 12 and the support rods 12 forms a funnel shape upwards, and the rotating rod 22 is closely attached to the electric pole upwards. At this time, the conical thorn structure faces outwards, which can further prevent animals from climbing; when a small animal climbs over the bottom of the elastic blocking cover 13 and jumps onto the annular fixing frame 11, the gravity sensor inside the annular fixing frame 11 reaches the preset threshold, sends a signal to the signal receiver, and rotates the rotating rod 22 downwards until the bottom of the rotating rod 22 touches the elastic blocking cover 13 through the control of the transmission device. At this time, the conical thorn structure stabs downwards to stimulate the small animal but does not cause it to be severely damaged. At the same time, an elastic blocking cover 13 can also be arranged between the rotating rods 22 to maintain a closed space after the bottom of the rotating rod 22 touches the elastic blocking cover 13; then, the elastic blocking cover 13 arranged between the support rods 12 and the support rods 12 is rotated downwards to form an umbrella-shaped structure through the plc controller, that is, the downward exit is opened. At this time, the irritating liquid in the sealing cylinder 121 drips drop by drop, then flows to the support rod 12 through the liquid permeating holes, and together with the stimulation of the conical thorn structure of the upper rotating rod 22, it forces the small animal to leave.
[0040] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
