Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of power systems, and particularly relates to a fence structure for a substation and a method for installing and dismounting the same. BACKGROUND

[0002] In the construction and maintenance of substations, a safety fence is crucial and is an implementation tool for safety measures performed by operation and maintenance personnel. The safety fence defines the working range of maintenance personnel during the maintenance work process, ensures that the working personnel maintain a safe distance from live equipment, and prevents accidental entry into a live interval, thereby causing accidents. The safety fence for a substation must be stable, and the installation of the fence must be eye-catching. At present, the phenomenon of the collapse of the safety fence of a substation occurs from time to time, and the phenomenon of private movement or crossing of the fence by the working personnel and accidental entry into a live interval is also common, which seriously endangers the personal safety and equipment safety in the substation.

[0003] In order to solve the problem of the collapse of the fence, improvement of the base of the fence rod is indispensable. In the prior art, various types of fence bases are available, mainly including an iron disc base, a support base, or direct insertion of the fence rod into a green pool. The iron disc base has a large mass and a low center of gravity, and thus the structure is relatively stable, but is inconvenient to carry; the support base is relatively light in weight, and is convenient to store and carry, but is easily affected by external forces and is prone to collapse; and the structure of direct insertion of the fence rod into a green pool is simple and has high stability, but is easily limited by site factors, and if there is no special insertion hole or a nearby green pool in the working site, the structure cannot be used. Furthermore, in order to prevent the accidental entry of working personnel into a live interval, not only eye-catching warning signs are required, but also strong visual and auditory warnings are required. The effect of the safety fence and the warning device used in the substation is not obvious, and the protection capability is weaker, especially at night during rush repair work. SUMMARY

[0052] Example 1

[0053] like Figure 1 As shown, this embodiment provides a fence structure for a substation, including a base 1, fence posts 2, signboards 3, a monitoring and alarm device 4, and a fence net 5. The fence posts 2 are fixed to the upper center of the base 1 and include an upper telescopic railing 20, a lower support railing 200, and an anti-detachment hook 21. The signboards 3 are set on both sides of the fence posts 2 via a snap-fit ​​structure 24 to indicate the working areas, and the signboards 3 are all grid-shaped except for the font. The base 1 includes a liquid accumulation chamber, a fixed housing 100, a snap-fit ​​structure, a support spring, a liquid inlet 111, and a liquid outlet 112. The monitoring and alarm device 4 is fixed on a platform on the upper part of the base 1. Furthermore, the top view of the base 1 is a regular hexagon. The regular hexagon can occupy the largest area with the least amount of material, which is beneficial to the adhesion of the base 1 to the ground.

[0054] like Figure 2 As shown, the upper and lower surfaces of the base 1 are respectively provided with upwardly extending protruding structures. The cross-section of the protruding structure is trapezoidal, that is, the lower surface of the base 1 is concave inward with a trapezoidal cross-section, and the upper surface protrudes outward with the same trapezoidal cross-section to form a hexagonal support structure. The support force is relatively balanced in all directions, which can avoid excessive local stress. At the same time, the bottom surface of the base 1 is concave inward with a trapezoidal cross-section, which can minimize the contact area between the base 1 and the ground, so that the fence can rely less on the ground and can be used on cement ground, green ground and gravel ground, etc., and also allows the center of gravity of the base 1 to be close to the ground.

[0055] In addition, the base 1 has a cylindrical fixed housing 100 with an upward opening in the center. The outer side of the fixed housing 100 is a hydrops chamber. The upper platform of the hydrops chamber has an inlet 111. The lowest side of the hydrops chamber has an outlet 112. The inlet 111 and the outlet 112 are respectively connected with a detachable inlet plug 1110 and an outlet plug 1120 using threads and sealing rings in use. Specifically, the inlet plug 1110 and the outlet plug 1120 can be made of stainless steel, galvanized steel, or aluminum alloy, etc., which have high strength and anti-corrosion characteristics. The sealing ring used for connection can be made of butyl rubber, which has good water resistance, air tightness, and excellent adhesion.

[0056] In order to realize the function of adjusting the size of the hydrops chamber, the outer shell of the hydrops chamber is composed of hard shells and soft shells connected alternately. Specifically, the outer shell includes a first hard shell 11, a second hard shell 12, and a third hard shell 13 arranged from bottom to top. The first hard shell 11 and the second hard shell 12 are connected by a soft shell 110, and the second hard shell 12 and the third hard shell 13 are also connected by a soft shell 110. Further, the hard shell can be made of polystyrene or polyformaldehyde, which has excellent mechanical strength, hardness, and wear resistance, and has the effect of being light and durable. The soft shell 110 can be made of polypropylene, which has good plasticity, durability, and water resistance, and can withstand multiple stretching and folding without damage or leakage. When less or no liquid 6 is injected from the inlet 111, the soft shell 110 can be folded between the hard shells to reduce the overall volume of the base 1. When more liquid 6 is injected, as shown in the figure, the soft shell 110 can be stretched to increase the volume of the hydrops chamber, so that the base 1 has several times its own gravity, thereby being able to stabilize the substation fence and avoid its collapse. Figure 6

[0057] As shown in the figure, the base 1 has a cylindrical fixed housing 100 with an upward opening in the center. The outer side of the fixed housing 100 is a hydrops chamber. The upper platform of the hydrops chamber has an inlet 111. The lowest side of the hydrops chamber has an outlet 112. The inlet 111 and the outlet 112 are respectively connected with a detachable inlet plug 1110 and an outlet plug 1120 using threads and sealing rings in use. Specifically, the inlet plug 1110 and the outlet plug 1120 can be made of stainless steel, galvanized steel, or aluminum alloy, etc., which have high strength and anti-corrosion characteristics. The sealing ring used for connection can be made of butyl rubber, which has good water resistance, air tightness, and excellent adhesion. Figures 3-4 ​As shown, the fixed housing 100 has a buckle structure inside, and the buckle structure is coaxially arranged between the fixed housing 100, specifically, the buckle structure includes a clamping piece 103, a pressing piece 104, a rotating rod 105, an inclined guide piece 106, a bottom guide piece 107, a buckle housing 108 and a compression spring 109; wherein the clamping piece 103 is matched with the lower end of the fence rod 2 and is hinged on the top of the two sides of the pressing piece 104, one end of the rotating rod 105 is connected to the lower part of the pressing piece 104, and the other end can freely move on the inclined guide piece 106, when the fence rod 2 is inserted into the buckle structure in the upper center of the base 1, the pressing piece 104 is pressed downward to move the compression spring 109 downward, and then drives the lower end of the rotating rod 105 to move downward along the left inclined surface of the inclined guide piece 106 to the lower groove of the inclined guide piece 106, at the same time, the two clamping pieces 103 on the upper part of the pressing piece 104 are driven to shrink inward into the buckle housing 108, so that the fence rod 2 can be clamped on the bottom of the fence rod 2, that is, the fence rod 2 can be fixed on the base 1, and the compression spring 109 will be further compressed, as shown. Figure 3 As shown.

[0058] Through the clamping design of the clamping piece 103 and the clamping boss, when the fence rod 2 is fixed on the base 1, the fence rod 2 can rotate 360° in the horizontal direction to facilitate the adjustment of the direction of the anti-off hook 21 and the signboard 3, when the fence rod 2 fixed on the base 1 is further pressed downward, the lower end of the rotating rod 105 is out of the groove of the inclined guide piece 106, and moves upward along the right inclined surface of the inclined guide piece 106, at this time, the compression spring 109 restores the deformation to provide upward force to the pressing piece 104, so that the pressing piece 104 moves upward, thereby driving the two clamping pieces 103 to move out of the buckle housing 108 and open outward, and the fence rod 2 can be removed from the base 1, as shown. Figure 4 As shown, the design makes the installation and disassembly of the base 1 and the fence rod 2 very convenient, in addition, the material of the buckle structure can be stainless steel, which has good rigidity and wear resistance.

[0059] Further, as shown. Figure 5As shown, the buckle structure is connected between the upper support spring 101 and the lower support spring 102 and the fixed shell 100 to provide elastic force (F1, F2, F3) in the vertical direction, so that the buckle shell 108 forms a tilting structure inside the fixed shell 100. In this way, the buckle structure is always in a vertical state inside the fixed shell 100 without external force, and even if there is external force, the buckle structure always has a force tending to be vertical inside the fixed shell 100. At the same time, the opening diameter of the fixed shell 100 is larger than the diameter of the bottom of the fence rod 2. When the fence rod 2 or the net 5 is subjected to pressure, the fence rod 2 can drive the buckle structure to rotate within a certain angle α range. When the pressure is removed, the fence rod 2 quickly recovers to a vertical state under the action of the support spring. This tilting structure allows the fence rod 2 to have a certain degree of freedom in the horizontal direction, effectively avoiding tilting.

[0060] As shown in Figure 2 The lower part of the upper telescopic fence rod 20 of the fence rod 2 has a cylindrical positioning button 23, and the lower support fence rod 200 has a plurality of adjustment holes 22 uniformly arranged along the height direction. The height of the fence can be changed by changing the position of the cylindrical positioning button 23 of the upper telescopic fence rod 20 in the adjustment hole 22 of the lower support fence rod 200. The maximum height is Lmax and the minimum height is Lmin.

[0061] As shown in Figures 8-10 The anti-disengagement hook 21 of the fence rod 2 includes a fixed part 211 and a movable part 212, and the fixed part 211 and the movable part 212 are connected by a torsion spring assembly 213. Specifically, the torsion spring assembly 213 includes a rotating shaft 2132 and a torsion spring 2131 arranged on the rotating shaft 2132. When the edge or corner of the net 5 needs to be fixed on the fence rod 2 during work, the movable part 212 can be opened to put the edge or corner of the net 5 in this way. At this time, the torsion spring assembly 213 will be elastically deformed. When the edge or corner of the net 5 is put in, the external force is removed, and the torsion spring assembly 213 restores the deformation, so that the movable part 212 restores to the closed state under the action of the elastic force of the torsion spring assembly 213, thereby fixing the net 5 on the fence rod 2. The anti-disengagement hook 21 is arranged at least one on each side of the upper end of the upper telescopic fence rod 20 and the lower end of the lower support fence rod 200. The material of the anti-disengagement hook 21 can be polystyrene, which has good rigidity and wear resistance.

[0062] As shown in Figure 11As shown, the monitoring alarm device 4 can be a visible light, infrared light or radar signal generating, receiving device 42 and a sound, light alarm device 41, the signal generating, receiving device 42 is monitored in real time, and forms a set of electronic fences 7 in the working area, and through the design of the monitoring alarm device 4 which can be adjusted up and down, the electronic fence 7 of different heights can be set, specifically, the electronic fence 7 is located inside the net 5, and has an open entrance, when the staff or the object contacts or crosses the electronic fence 7, the monitoring alarm device 4 will send a sound, light alarm signal to remind the person in charge to timely remind or handle the abnormal situation; further, the distance between the electronic fence 7 and the net 5 is d, and the rotation angle α of the fence rod 2 when the fence rod 2 is subjected to pressure should satisfy: tan α < d / Lmax, so that the rotating fence rod 2 and the net 5 can avoid touching the electronic fence 7 to cause an alarm signal.

[0063] In order to realize the mutual stacking of the bases 1, first grooves 114 and second grooves 113 matched with the liquid inlet plugs 1110 and the monitoring alarm devices 4 are respectively arranged on the bottom surfaces of the bases 1, and the sizes of the first grooves 114 and the second grooves 113 are slightly larger than the sizes of the liquid inlet plugs 1110 and the monitoring alarm devices 4, when every two bases 1 are stacked with each other, the lower bottom surface of one base 1 can be closely combined with the upper surface of another base 1, which is convenient for carrying and storing the bases 1, and can also avoid horizontal sliding when stacking, and the stability is better.

[0064] Further, the two sides of the fence rod 2 also have a plug buckle structure 24 matched with the signboard 3, wherein the signboard 3 mainly includes a "from here to enter and exit" signboard A, a "stop, high voltage danger" signboard B and a "work here" signboard C, the "from here to enter and exit" signboard A and the "work here" signboard C are located at the entrance and exit, and the "stop, high voltage danger" signboard C is located at the edges and corners around the working area, and the signboard 3 can be a net-shaped cuboid plastic, so as to avoid a large windward area.

[0065] As shown, Figure 13 The application provides a mounting method of the fence structure for the transformer substation, and the mounting method comprises the following steps:

[0066] S1, placing the base 1 on the edges and corners of the working area;

[0067] S2, injecting the liquid 6 into the liquid accumulation cavity through the liquid inlet 111;

[0068] S3, inserting the fence rod 2 into the fixed shell 100 and extruding the buckle structure downward to realize clamping fixation;

[0069] S4, fixing the net 5 on the anti-dropping hook 21 of the fence rod 2 to enclose the working area, and leaving an entrance and exit on one side of the working area;

[0070] S5. Insert the sign 3 into both sides of the fence post 2 to indicate the work area;

[0071] S6. Activate the monitoring and alarm device 4 to form an electronic fence 7.

[0072] During the work process, when a person or object touches or crosses the electronic fence 7, the monitoring alarm device 4 will issue an alarm signal. The person in charge of the work can handle the abnormal situation in time and reset the alarm signal.

[0073] like Figure 14 As shown, the present invention provides a disassembly method after installation using the above-described installation method, comprising the following steps:

[0074] a1. When the work is finished, turn off the monitoring and alarm device 4;

[0075] a2. Remove the fence netting 5 from the anti-detachment hook 21 on the fence post 2;

[0076] a3. Press down on the fence post 2 again to remove the fence post 2 from the fixed housing 100;

[0077] a4. Drain the liquid 6 in the accumulation chamber from the liquid outlet 112;

[0078] a5. Recycle the base 1, fence post 2, and netting 5 separately.

[0079] Example 2

[0080] like Figure 12 As shown, the structure of this embodiment is basically the same as that of Embodiment 1. The difference lies in the structural arrangement of the liquid accumulation chamber. In order to further ensure the stability of the liquid accumulation chamber and avoid leakage problems caused by repeated expansion and contraction at the connection between the soft shell or the hard shell and the soft shell, a flexible liquid storage bladder communicating with the liquid inlet 111 and the liquid outlet 112 is provided inside the liquid accumulation chamber. The flexible liquid storage bladder can be adjusted according to the expansion and contraction of the liquid accumulation chamber volume. In this way, the liquid storage effect can be further guaranteed and the service life can be extended.

[0081] In summary, the substation fence structure and its installation and dismantling method provided by this invention can separate and store the base, fence posts and fence netting, which has the advantages of easy storage and transportation. The use of liquid injection in the accumulating chamber to increase weight significantly reduces the weight of the fence structure itself. It also overcomes the bottleneck of fences being prone to tipping over in various application scenarios, and can provide clear warnings for workers who move or cross the fence without authorization, making it intelligent and convenient.

[0082] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
