[0025] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0026] like Figure 1-Figure 6 FIG. 1 shows a first embodiment of the electric fence pole base structure for a substation according to the present invention.

[0027] The electric fence pole base structure for a substation in this embodiment is used to adapt to the electric fence pole to form a safety fence net, including: an outer cylinder 2, which is a hollow structure with openings at both ends, and a cone cover 9 is installed at one end of the outer cylinder 2; a guide inner cylinder 7 installed on one end side of the outer cylinder 2; a rotating column 4 installed in the guide inner cylinder 7; a track slide column 3 adapted to be connected to the rotating column 4, one end of the track slide column 3 is sleeved in the guide inner cylinder 7, and the end of the track slide column 3 and the middle of the rotating column 4 are respectively provided with matching gears to drive the rotating column to rotate when the track slide column moves along the guide inner cylinder.

[0028] A ground pile 1 connected to the track sliding column 3 can be pressed and retracted relative to the outer cylinder 2, and the ground pile 1 is used to insert into the hollow electric fence pole; a limiting inner cylinder 5 is installed on the other end side of the outer cylinder 2, and an axial maintaining member 8 is provided in the limiting inner cylinder 5, and the axial maintaining member 8 is connected to the track sliding column 3; an elastic reset member 6 is installed in the limiting inner cylinder 5, one end of the elastic reset member 6 is connected to the axial maintaining member 8, and the other end is connected to the cone cover 9, wherein: pressing the ground pile 1 links the track sliding column 3, the rotating column 4 and the axial maintaining member 8 to squeeze the elastic reset member 6, and the rotating column 4 rotates relative to the track sliding column 3 to adjust the relative clamping position of the rotating column 4 and the guide inner cylinder 7.

[0029] In specific implementation, the ground pile 1 is cylindrical and can be installed upward from the bottom of the outer tube 2. The function of the ground pile 1 is to limit the maximum lift of the ground installation, and its lift in this embodiment is 40mm. The cylindrical diameter of the ground pile 1 is 23mm, which is just suitable for inserting into the hollow electric fence pole with an inner diameter of 25mm. In implementation, the ground pile 1 that pops out of the outer tube 2 can be plugged into the hollow stainless steel fence pole, which can bear the weight of the fence pole itself and prevent wind.

[0030] Preferably, four claws are provided at the bottom of the ground pile 1, which are four-claw limiters and limit the maximum depth. When the ground pile 1 is ejected, the outer surface is red to remind people not to get hurt.

[0031] The outer cylinder 2 is the main part of the electric fence pole base structure support and fixation. The function of the outer cylinder 2 is to protect the internal components and a certain protective effect, and it is also the main part of the main body support and fixation. The outer cylinder 2 in this embodiment is in the shape of an umbrella, slightly higher in the middle and slightly lower on the outer circumference, and has a certain drainage effect.

[0032] Preferably, the outer tube 2 has four small barbs on the outside, which can increase stability after being buried underground. The outer tube 2 fits the ground after assembly to improve the grip. Once installed into the soil or cement floor, it is not easy to pull out, making the whole body stable.

[0033] Furthermore, the rotating column 4 is a rotatable moving part, and its function is to adapt and connect with the track slide column 3 to convert the vertical motion into circular motion. The end side of the rotating column 4 connected to the track slide column 3 is cylindrical, and the end side of the track slide column 3 with a protrusion is sleeved on the cylindrical end side of the rotating column 4. The end of the track slide column 3 and the middle of the rotating column 4 are respectively provided with matching gears, so as to drive the rotating column to rotate when the track slide column moves along the guide inner cylinder.

[0034] In this embodiment, the outer circumference of the rotating column 4 is provided with three large protrusions, which can move in the deep groove. The upper cylinder of the rotating column 4 can be installed into the track, the internal cavity of the slide column, so that the gears on the track slide column 3 and the rotating column 4 are adapted.

[0035] The limiting inner cylinder 5 plays the role of limiting the axis, and is installed at the bottom of the outer cylinder 2. The limiting inner cylinder 5 can ensure that the structural parts installed therein can move on the axis.

[0036] Furthermore, the elastic reset member 6 is a spring in this embodiment, and is made of stainless steel. The function of the elastic reset member 6 is to utilize the contraction and springing operating energy of the built-in spring to achieve the retention and recovery of the spring-pushing pile 1 through the track slide column 3, the rotating column 4, and the axial retaining member 8, thereby matching the commonly used hollow electric fence poles, and can play a reliable fixing and supporting role in cement ground and mud ground environments.

[0037] Furthermore, deep tracks and shallow tracks are arranged at intervals on the guide inner cylinder 7 , and protrusions corresponding to the deep tracks and the shallow tracks are arranged on the outer periphery of the track slide post 3 , so as to enable the track slide post 3 to reciprocate relative to the guide inner cylinder 7 .

[0038] Preferably, a suspension groove is provided on the guide inner cylinder 7. When the gear in the middle of the rotating column 4 is clamped in the suspension groove or rotated out of the suspension groove, the relative telescopic length of the rotating column 4 relative to the guide inner cylinder 7 can be adjusted, thereby adjusting the relative clamping position of the rotating column 4 and the guide inner cylinder 7.

[0039] Preferably, the guiding inner cylinder 7 is connected to the limiting inner cylinder 5 .

[0040] Furthermore, the function of the axial maintaining member 8 is to keep the upper and lower components moving coaxially up and down, reduce component friction and vibration, and at the same time, can also play the role of fixing the elastic reset member 6.

[0041] Preferably, a cavity is provided at the bottom of the axial maintaining member 8, and the cone cover 9 has a cylindrical end side limited in the cavity, and the coaxial limiting structure provides double protection for the limiting.

[0042] Furthermore, the cone cover 9 is circular and has threads thereon, and the cone cover 9 can be threadedly connected and installed on the outer cylinder 2. After assembly, multiple internal components can be tightly connected without shaking up and down, and the conical structure at the bottom of the cone cover 9 can reduce the resistance of the entire pile when entering the ground.

[0043] In the specific implementation of the electric fence pole base structure for a substation in this embodiment, when the pile 1 is in a rebound state or just beginning to be pressed down, the three large protrusions on the rotating column 4 will move up and down in the three deep grooves, and the component cannot rotate at this time. At this time, the gears on the track sliding column 3 and the rotating column 4 cannot be fully matched and are exactly half a tooth apart.

[0044] When the pile 1 continues to press downward, the track slide column 3 will push the rotating column 4 out of the vertical slide rail, and the gear of the rotating column 4 will rotate for the first time under the elastic force of the elastic reset member 6. At this time, the external pressing force is released, and the rotating column 4 and the track slide column 3 move upward under the elastic force of the spring 6, and the middle gear of the rotating column 4 will cooperate with the track gear inside the track.

[0045] Then, under the action of the elastic force of the spring 6, the rotating column 4 will slide relative to the middle gear of the track and slide into the suspension groove, and the base mechanism of the electric fence pole will stop. From the outside, the ground pile 1 is parallel to the top surface of the outer tube 2 and is retracted into the ground. Press the ground pile 1 again. Under the action of pressure, the track sliding column 3 and the rotating column 4 move downward. The middle gear of the rotating column 4 will be separated from the suspension groove under the pressure. Continuing to move downward will trigger the four claws at the bottom of the ground pile 1. It is impossible to continue to press downward and reach the maximum pressing depth. At this time, the external pressure is released, and the track sliding column 3 and the rotating column 4 move upward under the action of the spring elastic force. The middle gear of the rotating column 4 contacts the internal gear of the track again. The inclined tooth shape converts the upward elastic force of the spring 6 into an oblique upward force. At this time, the three large protrusions of the rotating column 4 slide into three deep grooves again. Continuing to move upward will reach the maximum lift. At this time, the ground pile 1 is at the maximum height. The ground pile 1 can be plugged into the hollow stainless steel fence pole, which can bear the weight of the fence pole itself and prevent wind.

[0046] The electric fence pole base structure for the substation in this embodiment can be pre-buried in the ground and has the performance advantage of "one-click pop-up, one-click retraction". It can be popped out by stepping on it when in use, and inserted into the fence pole. When stored, it can be retracted to the ground by stepping on it. At the same time, the base of the electric fence pole is almost flush with the ground when stored, which does not affect the passage of pedestrians and inspection robots; it has a simple structure and strong practicality, and is more economical than the traditional discus base. As a part of the electric fence, it needs to be spread throughout the substation equipment site and has a large quantity demand, which has an unexpected technical effect of reducing costs and increasing efficiency.
