Description

Technical Field

[0001] The utility model relates to the technical field of electric pole protection, in particular to an electric pole anti-snake climbing device. Background Art

[0002] With the continuous development of power grids and the increasing needs of the people, power distribution lines have extended to every corner of cities and rural areas. They are also gradually appearing in sparsely populated rural areas, remote areas, and forested areas. Electric poles are one of the key infrastructure of power distribution lines, supporting the safe operation of power lines at high altitudes. However, the operating environment of electric poles is relatively complex and they are highly susceptible to damage by snakes and other animals. To prevent such accidents, snake-proofing devices are often installed on electric poles.

[0003] For example, the utility model with application number CN202021240381.8 discloses a device for preventing small animals from climbing on electric poles. After the utility model adopts such a design, when a snake climbs to the position of the umbrella, the tension sensor detects that the tension is greater than the preset value (3N), the motor is powered on, the self-locking is released, the tightening rope is loosened, and the sliding ring falls, thereby causing the umbrella to shrink and close quickly, causing the snake that has just climbed onto the umbrella to slide down, thus effectively preventing the snake from climbing to the upper end of the tower. However, the support ring is usually an adaptable type for the pole, that is, a support ring is only suitable for poles of one size, which limits the scope of application of the device and reduces the practicability of the device.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an anti-snake climbing device for electric poles is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a snake-proof climbing device for electric poles to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: an anti-snake climbing device for electric poles, comprising an upper counterweight frame and a guide block, the upper counterweight frame is connected to an upper covering plate on all four sides through a rotating shaft 1, and the middle of the bottom end of the upper covering plate is connected to a lower covering plate through a rotating shaft 2, the middle of the bottom end of the lower covering plate is connected to a lower counterweight frame through a rotating shaft 3, and pressure sensors are provided on the surfaces of the upper and lower covering plates, the guide block is fixed to the top of the upper counterweight frame, and a clamping seat is provided above the upper counterweight frame, bolts are screwed into the screw holes on the surface of the clamping seat, and nuts are screwed into the outside of the bolts, an auxiliary component is installed on the right side of the bottom of the upper counterweight frame, and the auxiliary component comprises a forward and reverse motor, a winding roller and a pull rope, the output end of the forward and reverse motor is connected to the winding roller, and the outside of the winding roller is connected to the pull rope.

[0007] The upper sealing plates and the lower sealing plates are provided in the same number, and the upper sealing plates are distributed in a ring shape along the outer side of the upper counterweight frame.

[0008] The lower sealing plate is distributed in a ring shape along the outer side of the lower counterweight frame, and the upper counterweight frame and the lower counterweight frame are coaxially arranged.

[0009] The upper counterweight frame is a hollow structure, and the guide blocks are distributed in a circular and equidistant manner about the center position of the upper counterweight frame.

[0010] The guide blocks and the clamping seats are each provided with four groups, and the guide blocks are T-shaped structures.

[0011] Two adjacent clamping seats are connected to each other via bolts, and the number of clamping seats, bolts and nuts is the same.

[0012] The end of the pull rope away from the unwinding roller is fixedly connected to the lower counterweight frame, and the setting ratio of the forward and reverse motors, the unwinding roller and the pull rope is 1:1:2.

[0013] The utility model provides a device for preventing snakes from climbing on electric poles, which has the following beneficial effects:

[0014] 1. In the present invention, since the surface of the clamping seat is provided with a slide groove that matches the size of the bottom end of the guide block, after the guide block contacts the clamping seat and forms a guiding effect, the clamping seat is moved toward or away from the center of the upper counterweight frame and fixed with bolts and nuts. This allows the device to fit poles of different diameters, effectively increasing the practicality of the device.

[0015] 2. In the present invention, since the pressure sensor and the forward and reverse motors are electrically connected to the controller, when a snake climbs onto any lower counterweight frame, the pressure sensor is used to detect the pressure. When the pressure value is greater than the threshold, the controller starts the forward and reverse motors, and drives the unwinding roller to rotate through the forward and reverse motors to reel in the pull rope, so that when the lower counterweight frame moves vertically upward along the pole, the upper and lower closing plates instantly have a larger inclination angle, thereby preventing the snake from continuing to climb upward.

[0020] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] like Figure 1 and Figure 2 As shown, the anti-snake climbing device for electric poles includes an upper counterweight frame 1 and a guide block 9. The guide block 9 is fixed to the top of the upper counterweight frame 1, and a clamping seat 10 is arranged above the upper counterweight frame 1. Bolts 11 are screwed to the screw holes on the surface of the clamping seat 10, and nuts 12 are screwed to the outside of the bolts 11. The upper counterweight frame 1 is a hollow structure, and the guide blocks 9 are distributed in a circular and equidistant manner about the center position of the upper counterweight frame 1. Four groups of guide blocks 9 and clamping seats 10 are each provided, and the guide blocks 9 are T-shaped. Two adjacent clamping seats 10 are connected to each other by bolts 11, and the number of clamping seats 10, bolts 11 and nuts 12 is the same.

[0022] The specific operation is as follows: since the surface of the clamping seat 10 is provided with a sliding groove that matches the size of the bottom end of the guide block 9, after the guide block 9 contacts the clamping seat 10 and forms a guiding effect, by moving the clamping seat 10 toward or away from the center of the upper counterweight frame 1 and fixing it with bolts 11 and nuts 12, the device can fit poles of different diameters, effectively increasing the practicality of the device.

[0023] like Figures 1 to 3As shown, the upper counterweight frame 1 is connected to the upper sealing plate 3 around the four corners through the rotating shaft 1 2, and the middle of the bottom end of the upper sealing plate 3 is connected to the lower sealing plate 5 through the rotating shaft 2 4, and the middle of the bottom end of the lower sealing plate 5 is connected to the lower counterweight frame 7 through the rotating shaft 3 6, and the surfaces of the upper sealing plate 3 and the lower sealing plate 5 are both provided with a pressure sensor 8, and an auxiliary component 13 is installed on the right side of the bottom of the upper counterweight frame 1, and the auxiliary component 13 includes a forward and reverse motor 1301, a winding roller 1302 and a pull rope 1303, and the output end of the forward and reverse motor 1301 is connected to the winding roller 1 302, and a pull rope 1303 is connected to the outside of the unwinding roller 1302, the upper sealing plate 3 and the lower sealing plate 5 are set in the same number, and the upper sealing plate 3 is distributed in a ring shape along the outer side of the upper counterweight frame 1, and the lower sealing plate 5 is distributed in a ring shape along the outer side of the lower counterweight frame 7, and the upper counterweight frame 1 and the lower counterweight frame 7 are coaxially arranged, the end of the pull rope 1303 away from the unwinding roller 1302 is fixedly connected to the lower counterweight frame 7, and the setting ratio of the forward and reverse motor 1301, the unwinding roller 1302 and the pull rope 1303 is 1:1:2.

[0024] The specific operation is as follows: since the pressure sensor 8 and the forward and reverse motor 1301 are electrically connected to the controller, when the snake climbs onto any lower counterweight frame 7, the pressure sensor 8 is used to detect the pressure. When the pressure value is greater than the threshold, the controller turns on the forward and reverse motor 1301, and drives the unwinding roller 1302 to rotate through the forward and reverse motor 1301 to reel in the pull rope 1303, so that when the lower counterweight frame 7 moves vertically upward along the pole, the upper cover plate 3 and the lower cover plate 5 instantly have a larger inclination angle, thereby preventing the snake from continuing to climb upward.

[0025] In summary, when the electric pole anti-snake climbing device is used, the upper counterweight frame 1 is first set on the electric pole, and the clamping seat 10 is moved according to the size of the electric pole. Since the surface of the clamping seat 10 is provided with a sliding groove that matches the size of the bottom end of the guide block 9, the guide block 9 contacts the clamping seat 10 and forms a guiding effect. The clamping seat 10 can always keep moving in the direction close to or away from the center of the upper counterweight frame 1 to avoid deviation. When the four groups of clamping seats 10 are fitted with the electric pole, the bolts 11 are screwed into the screw holes on the surfaces of two adjacent clamping seats 10, and then fixed with the nuts 12 to prevent the device from falling off the electric pole. This design makes the device adjustable and can better fit the electric poles of different diameters, effectively increasing the practicality of the device.

[0026] Since the upper sealing plate 3 and the lower sealing plate 5 are kept vertically under the influence of the gravity of the lower counterweight frame 7,

[0027] The four upper sealing plates 3 and the four lower sealing plates 5 surround the pole, and the clamping seat 10 blocks the opening of the upper counterweight frame 1, so that small animals such as snakes cannot climb up the pole;

[0028] When a snake or other small animal climbs onto any lower counterweight frame 7, the pressure sensor 8 is used to detect the pressure. When the pressure value is greater than the threshold, the controller controls the forward and reverse motor 1301 to work, and drives the unwinding roller 1302 to rotate through the forward and reverse motor 1301 to reel in the pull rope 1303, so that when the lower counterweight frame 7 moves vertically upward along the pole, the upper cover plate 3 and the lower cover plate 5 instantly have a larger tilt angle. At this time, small animals such as snakes lose stability and fall, achieving the effect of preventing snakes from climbing.

[0029] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
