Description

TECHNICAL FIELD

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

[0002] In the construction and maintenance of a transformer substation, a safety fence is of great importance and is an implementation tool for safety measures performed by operation and maintenance personnel. The safety fence defines the working range of the maintenance personnel during the maintenance work, ensures that the working personnel maintain a safe distance from the live equipment, and prevents the personnel from entering a live interval by mistake, thereby causing an accident. The safety fence for a transformer substation must be stable, and the installation of the fence must be eye-catching. Currently, the phenomenon of the safety fence for a transformer substation being knocked down occurs from time to time, and the phenomenon of the working personnel moving or crossing the fence by themselves and entering a live interval by mistake also occurs frequently, which seriously endangers the safety of the personnel and equipment in the transformer substation.

[0003] In order to solve the problem of the fence being knocked down, the improvement of the base of the fence rod is indispensable. In the prior art, various types of fence bases exist, mainly including an iron disc base, a bracket base, or a structure in which the fence rod is directly inserted 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 the iron disc base is inconvenient to carry. The bracket base is relatively light in weight, and thus the bracket base is convenient to store and carry, but the bracket base is easily affected by external forces and is easily knocked down. The structure in which the fence rod is directly inserted into a green pool is simple and has high stability, but the structure is easily limited by the site, and if there is no special socket or a nearby green pool in the working site, the structure cannot be used. Furthermore, in order to prevent the working personnel from entering a live interval by mistake, not only eye-catching warning signs are needed, but also strong visual and auditory warnings are needed. The effect of the safety fence for a transformer substation and the warning device used in the transformer substation is not obvious, and especially during night repair work, the protection capability is weaker.

[0024] Example One

[0025] As Figure 1 shown, the embodiment provides a fence structure for transformer substation, including base 1, fence pole 2, signboard 3, monitoring alarm device 4 and net 5; fence pole 2 is fixed on the upper central part of base 1, including upper telescopic pole 20, lower support pole 200 and anti-drop hook 21; signboard 3 is set on both sides of fence pole 2 by inserting buckle structure 24 for indicating each working area, and signboard 3 is designed in grid shape except the identification font; base 1 includes liquid accumulation cavity, fixed shell 100, buckle structure, support spring, liquid inlet 111 and liquid outlet 112; monitoring alarm device 4 is fixed on the platform on the upper part of base 1; further, the top view of base 1 is a regular hexagon, which can occupy the maximum area with the least material, which is beneficial to the adhesion of base 1 to the ground.

[0026] As Figure 2 shown, the upper surface and the lower surface of base 1 are respectively provided with upward extending convex structures, the cross section of the convex structure is trapezoidal, that is, the lower surface of base 1 is inwardly recessed with trapezoidal cross section, and the upper surface is outwardly protruded with the same trapezoidal cross section to form a hexagonal support structure, the support force is relatively balanced in each direction, which can avoid excessive local stress, at the same time, the bottom surface of base 1 is inwardly recessed with trapezoidal cross section, which can minimize the contact area of base 1 with the ground, so that the fence can be less dependent on the ground state, which can be used on cement ground, green ground and gravel ground, etc., also makes the center of gravity of base 1 close to the ground.

[0027] In addition, the central part of base 1 has a cylindrical fixed shell 100 with an upward opening, the outer side of fixed shell 100 is a liquid accumulation cavity, the upper platform of liquid accumulation cavity has a liquid inlet 111, the lowest side of liquid accumulation cavity has a liquid outlet 112, the liquid inlet 111 and the liquid outlet 112 are respectively plugged by detachable liquid inlet plug 1110 and liquid outlet plug 1120 connected by thread and sealing ring in use, specifically, the material of liquid inlet plug 1110 and liquid outlet plug 1120 can be stainless steel, galvanized steel or aluminum alloy, etc., which has the characteristics of high strength and anti-corrosion, the material of sealing ring used for connection can be nitrile rubber, which has good water resistance, air tightness and excellent adhesion.

[0028] In order to realize the function of adjusting the size of the liquid cavity, the shell of the liquid cavity is composed of hard shell and soft shell staggered connection, specifically, including the first hard shell 11, the second hard shell 12 and the third hard shell 13 arranged from bottom to top, wherein the first hard shell 11 and the second hard shell 12, and the second hard shell 12 and the third hard shell 13 are connected by the soft shell 110, further, the hard shell material can be polystyrene, polyformaldehyde, etc., which has excellent mechanical strength, hardness and wear resistance, and has the effect of light and durable; the material of the soft shell 110 can be polypropylene, etc., which has good plasticity, durability and waterproofness, and can withstand multiple stretching, folding without damage and leakage; when less or no liquid 6 is injected from the liquid inlet 111, the soft shell 110 can be folded between the hard shell to reduce the overall volume of the base 1; when more liquid 6 is injected, as shown in Figure 6 , the soft shell 110 can be stretched to increase the volume of the liquid cavity, so that the base 1 has several times the gravity of itself, so as to be able to firmly support the substation fence and avoid its falling.

[0029] As shown in Figures 3-4 , the fixed shell 100 has a buckle structure inside, and the buckle structure is coaxially arranged between the fixed shell 100, specifically, the buckle structure includes a clamping piece 103, a pressing piece 104, a rotating rod 105, an inclined guide rail piece 106, a bottom guide rail piece 107, a buckle shell 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 pressing piece 104 on both sides, 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 rail 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 rail piece 106 to the lower groove of the inclined guide rail piece 106, at the same time, the two clamping pieces 103 on the upper part of the pressing piece 104 are driven to shrink into the buckle shell 108 by the downward movement of the pressing piece 104, so as to clamp the clamping boss at 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 in Figure 3 .

[0030] 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 through the clamping design of the clamping piece 103 and the clamping boss. 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 in the lower part 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 clamping pieces 103 on both sides to move out of the clamping shell 108 and open outward, so that the fence rod 2 can be detached from the base 1, as shown in Figure 4 The installation and disassembly of the base 1 and the fence rod 2 are very convenient, and the material of the clamping structure can be stainless steel, which has good rigidity and wear resistance.

[0031] Further, as shown in Figure 5 The clamping structure is connected between the upper supporting spring 101 and the lower supporting spring 102 and the fixed shell 100 to provide vertical elastic force (F1, F2, F3), so that the clamping shell 108 forms a “Topsy-Turvy” structure inside the fixed shell 100. In this way, the clamping structure is always in a vertical state inside the fixed shell 100 without external force, and even if there is external force, the clamping 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 clamping structure to rotate within a certain angle α range. When the pressure is removed, the fence rod 2 quickly recovers to the vertical state under the action of the supporting spring. This “Topsy-Turvy” structure makes the fence rod 2 have a certain degree of freedom in the horizontal direction, which can effectively avoid falling.

[0032] 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 part of the supporting fence rod 200 has a plurality of adjusting 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 adjusting hole 22 of the lower supporting fence rod 200, and the maximum height is Lmax and the minimum height is Lmin.

[0033] As shown in Figures 8-10As shown in the figure, the anti - detachment hook 21 of the railing 2 includes a fixing part 211 and a movable part 212. The fixing 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 edges and corners of the enclosure net 5 need to be fixed on the railing 2 during work, the movable part 212 can be opened to put the edges and corners of the enclosure net 5 in. At this time, the torsion spring assembly 213 will produce elastic deformation. After the edges and corners of the enclosure net 5 are put in, when the external force is removed, the torsion spring assembly 213 restores the deformation, so that the movable part 212 returns to the closed state under the action of the elastic force of the torsion spring assembly 213, fixing the enclosure net 5 on the railing 2; at least one anti - detachment hook 21 is provided on the left and right sides of the upper end of the telescopic railing 20 and the lower end of the lower support railing 200 of the railing; the anti - detachment hook 21 can be made of polystyrene, which has good rigidity and wear resistance.

[0034] As Figure 11 As shown in the figure, the monitoring and alarm device 4 can be a visible light, infrared light or radar signal generating and receiving device 42 and a sound and light alarm device 41. The signal generating and receiving device 42 monitors in real time and forms a set of electronic fences 7 in the working area. Through the design that the monitoring and alarm device 4 can be adjusted up and down telescopically, the setting of electronic fences 7 with different heights can be realized. Specifically, the electronic fence 7 is located inside the enclosure net 5 and has an open entrance and exit. When a staff member or an object touches or crosses the electronic fence 7, the monitoring and alarm device 4 will emit alarm signals such as sound and light, reminding the person in charge of the work to remind or handle abnormal situations in time; further, the distance between the electronic fence 7 and the enclosure net 5 is d, and the rotation angle α of the railing 2 when it is under pressure should satisfy: tanα < d / Lmax. In this way, it can be avoided that the rotating railing 2 and the enclosure net 5 touch the electronic fence 7 and cause alarm signals.

[0035] In order to realize the mutual stacking of the bases 1, first grooves 114 and second grooves 113 that are respectively matched with the liquid inlet plug 1110 and the monitoring and alarm device 4 are provided on the bottom surface of the base 1, and the sizes of the first grooves 114 and the second grooves 113 are slightly larger than the sizes of the liquid inlet plug 1110 and the monitoring and alarm device 4. When every two bases 1 are stacked on top of each other, the lower bottom surface of one base 1 can be closely fitted with the upper surface of another base 1, which is not only convenient for carrying and storing the bases 1, but also can avoid horizontal sliding during stacking, and has better stability.

[0036] Furthermore, the fence post 2 also has a snap-fit ​​structure 24 on both sides that connects with the sign 3. The sign 3 mainly includes three types: "Enter / Exit from Here" sign A, "Stop, High Voltage Danger" sign B, and "Work Here" sign C. "Enter / Exit from Here" sign A and "Work Here" sign C are located at the entrance and exit, while "Stop, High Voltage Danger" sign C is located around the edges and corners of the work area. The sign 3 can be a mesh rectangular plastic to avoid a large windward area.

[0037] like Figure 13 As shown, the present invention provides an installation method for the above-mentioned substation fence structure, comprising the following steps: S1. Place base 1 on the edge or corner of the work area; S2. Inject liquid 6 into the liquid accumulation chamber through the liquid inlet 111; S3. Insert the fence post 2 into the fixed housing 100 and press down the buckle structure to achieve a snap-fit ​​fixation; S4. Fix the netting 5 to the anti-detachment hook 21 of the fence post 2 to enclose the work area, and leave an entrance and exit on one side of the work area; S5. Insert the sign 3 into both sides of the fence post 2 to indicate the work area; S6. Activate the monitoring and alarm device 4 to form an electronic fence 7.

[0038] 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.

[0039] like Figure 14 As shown, the present invention provides a disassembly method after installation using the above-described installation method, comprising the following steps: a1. When the work is finished, turn off the monitoring and alarm device 4; a2. Remove the fence netting 5 from the anti-detachment hook 21 on the fence post 2; a3. Press down on the fence post 2 again to remove the fence post 2 from the fixed housing 100; a4. Drain the liquid 6 in the accumulation chamber from the liquid outlet 112; a5. Recycle the base 1, fence post 2, and netting 5 separately.

[0040] Example 2

[0041] like Figure 12As 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.

[0042] 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.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
