Description

Technical Field

[0001] The invention belongs to the field of electric power, in particular to a novel transformer substation protection device against small animal stings. Background Art

[0002] A substation is a place in the power system where voltage and current are transformed, electrical energy is received and distributed.

[0003] The substation in the power plant is a step-up substation, whose function is to step up the voltage of the electric energy generated by the generator and feed it into the high-voltage power grid.

[0004] The substation is the hub connecting various power grids, and its safety and stability directly affect the safety of the entire power grid system.

[0005] However, accidents involving small animals entering substations and causing equipment tripping do occur from time to time.

[0006] At present, the protection of substations from small animals mainly relies on daily inspections by operating personnel and fence electric grids. Gaps in the station gates, drainage holes and other gaps meet the "Five Connections" requirements. The fence electric grid, as an active intrusion prevention fence, counterattacks against intrusion attempts and greatly maintains the safety of the substation.

[0007] However, due to the geographical location of the substation and uncontrollable factors, the substation wall power grid cannot fully function.

[0008] For example, substations are usually located in open areas far away from residential areas, and there are tree barriers that cannot be removed around them, which causes frequent alarm signals from the fence power grid, causing interference to operation and maintenance personnel, who can only shield the signals;

[0009] Secondly, the gaps in the fence grid do not meet the requirements for preventing small animals. Small animals such as cats and weasels can still climb up the fence and enter the substation through the gaps in the fence grid, which seriously threatens the safe operation of equipment in the station and affects the normal operation of the substation. This does not meet people's requirements. For this reason, we have proposed a new type of substation to prevent small animals from pricking. Summary of the invention

[0010] In order to overcome the shortcomings of the prior art, the present application provides a new type of substation anti-small animal thorn device. When in use, steel nails are embedded in the upper outer part of the substation wall to form two "thorny" walls, one long and one short. This can effectively prevent small animals from climbing the wall to enter the substation, and can prevent people with ulterior motives from entering the substation and posing a threat to the power grid, with good protection effect.

[0011] The technical solution adopted by this application to solve its technical problems is:

[0012] A new type of substation protection against small animals, including a middle steel plate, upper triangular teeth and lower triangular teeth:

[0013] The middle steel plate is installed on the outer surface of the substation wall near the upper end;

[0014] The number of upper triangular teeth is several groups, and one end of the upper triangular teeth is detachably connected to the side surface of the middle steel plate;

[0015] The number of the lower triangular teeth is several groups, and one end of the lower triangular teeth is detachably connected to the other side surface of the middle steel plate;

[0016] Wherein, the upper triangular teeth and the lower triangular teeth are arranged at equal intervals.

[0017] A plurality of through openings are provided on the middle steel plate, metal isolation sleeves are arranged inside the through openings, and openings for steel nails to pass through are provided inside the metal isolation sleeves.

[0018] The metal isolation sleeve can play a protective role and reduce the deformation of the steel nails during use.

[0019] When in use, the middle steel plate is installed on the outer edge of the top of the fence by passing the steel nails through the opening on the middle steel plate and embedding it into the fence.

[0020] For jumping animals such as cats and weasels, or people who want to climb up the wall, the upper and lower triangular teeth are very sharp and form resistance to them, making it impossible for them to cross the saw teeth and enter the substation, or the saw teeth directly penetrate and stab them.

[0021] The present invention records a new type of substation anti-small animal thorn device. When in use, steel nails are embedded in the upper outer part of the substation wall to form two "thorny" walls, one long and one short. This can effectively prevent small animals from climbing the wall to enter the substation, and can prevent people with ulterior motives from entering the substation and posing a threat to the power grid, with good protection effect.

[0022] Preferably, the angle between the upper end surface of the upper triangular tooth and the upper end surface of the middle steel plate is 105°, and the angle between the upper end surface of the lower triangular tooth and the upper end surface of the middle steel plate is 45°.

[0023] The upper triangular teeth and the lower triangular teeth may also adopt other angles, and the angles mentioned above are the optimal solutions.

[0024] Preferably, the length of the upper triangular teeth is greater than the length of the lower triangular teeth, and the length of the lower triangular teeth is greater than the width of the middle steel plate.

[0025] When in use, the middle steel plate is selected to have a length of 1000 mm and a width of 25 mm.

[0026] The length of the upper triangular teeth is 150mm.

[0027] The length of the lower triangular teeth is 80mm.

[0029] The upper triangular teeth, lower triangular teeth and middle steel plate are all made of stainless steel.

[0030] The number of the upper triangular teeth and the lower triangular teeth is preferably 50.

[0031] The lower triangular teeth extend downward, and the sharp serrations act as a threat, forming the first line of defense to prevent it from climbing upward. If it breaks through the first line of defense and wants to continue climbing upward, it needs to grasp the upward fulcrum. The upper triangular teeth are designed to be longer than the lower triangular teeth, which can effectively prevent it from finding the upward fulcrum, serving as the second line of defense to prevent it from entering the substation.

[0032] Preferably, mounting grooves are formed at equal intervals on both sides of the middle steel plate, a limiting assembly is provided on the middle steel plate, and the upper triangular teeth and the lower triangular teeth are connected to the middle steel plate via the limiting assembly.

[0033] The upper triangular teeth and the lower triangular teeth are connected to the middle steel plate through a limit assembly, which adopts a movable connection method. When the upper triangular teeth and the lower triangular teeth are partially damaged, the damaged parts of the upper triangular teeth and the lower triangular teeth can be disassembled and replaced without replacing the entire device, and the use effect is good.

[0034] Preferably, a plug-in plate is provided at the lower end of the upper triangular teeth and the lower triangular teeth, and the plug-in plate is plugged into the mounting groove and connected to the middle steel plate through a limiting assembly.

[0035] The plug-in board is plugged into the installation slot, thereby limiting the upper triangular teeth and the lower triangular teeth to move in only one direction, and cooperates with the limiting effect of the limiting component to further limit the position, thereby completely limiting the position of the plug-in board, and the use effect is good.

[0036] Preferably, the limiting assembly includes a bar groove, a limiting strip, an elastic member and a limiting member:

[0037] The strip groove is opened on the upper end surface of the middle steel plate;

[0038] The limiting strip is arranged inside the strip groove;

[0039] The limiting strip is connected to the strip groove via an elastic member;

[0040] The limiting member is arranged on the lower end surface of the limiting strip;

[0041] A connecting groove is provided in the middle of the inner bottom surface of the strip groove, and the elastic member is a spring, and the two ends of the spring are respectively fixedly connected to the inner bottom surface of the connecting groove and the middle position of the lower end surface of the limiting strip.

[0042] A groove structure is provided in the middle of the lower end surface of the limiting strip, and the upper end of the spring is arranged in the groove structure.

[0043] When in use, the elastic force of the spring limits the position of the limit bar, so that the position of the limit piece on the limit bar is fixed, thereby achieving the limitation of the plug board.

[0044] A pulling column is arranged at the middle position of the upper end surface of the limiting strip.

[0045] When disassembling, pull the pulling column upwards, the pulling column drives the limit bar to move upwards, thereby driving the limit piece to move upwards, and the limit piece is separated from the plug-in board. At this time, pull the upper triangular teeth and the lower triangular teeth outwards.

[0046] Preferably, through holes are provided on the inner bottom surface of the strip groove near both ends, a connecting port is provided on the upper end surface of the plug board, and the limiting member includes two groups of limiting columns, the lower ends of the limiting columns pass through the through holes and extend to the inside of the connecting port.

[0047] When in use, the lower end of the limiting column passes through the through hole and extends to the inside of the connecting port, thereby fixing the position of the plug board and fixing the positions of the upper triangular teeth and the lower triangular teeth.

[0048] The present invention records a new type of substation protection against small animals. When in use, the upper triangular teeth and the lower triangular teeth are separately connected to the middle steel plate in a detachable manner. When part of the upper triangular teeth and the lower triangular teeth are damaged, the damaged part can be removed and directly replaced. In addition, the disassembly and installation of the upper triangular teeth and the lower triangular teeth are relatively convenient, which can facilitate the operation of the staff.

[0049] Preferably, the upper triangular teeth and the lower triangular teeth each include a main body and a movable part:

[0050] The plug board is fixedly connected to the main body;

[0054] The plug-in block is snap-connected with the plug-in slot to realize the connection between the movable part and the main body.

[0055] The upper and lower end surfaces of the plug-in block are both provided with triangular card blocks, and the plug-in slot is also provided with a groove structure corresponding to the shape of the triangular card block. The use of this structure can increase the contact area and make it more secure after plugging.

The gaps in the gates, drainage holes and other places in the station meet the requirements of the "Five Accesses". The wall power grid, as an active intrusion prevention fence, counterattacks against intrusion attempts, and also greatly maintains the safety of the substation. However, due to the geographical location of the substation and uncontrollable factors, the substation wall power grid cannot fully function. For example, substations are generally located in open places far away from residential areas, and there are tree barriers that cannot be removed around them, which causes the wall power grid to frequently send out alarm signals, causing interference to the operation and maintenance personnel, and they can only shield the signals; secondly, the gaps in the wall power grid do not meet the requirements for protection against small animals. Small animals such as cats and weasels can still climb up the wall and enter the substation through the gaps in the wall power grid, seriously threatening the safe operation of the equipment in the station and affecting the normal operation of the substation;

[0074] The present invention records a new type of substation anti-small animal thorn device. When in use, steel nails are embedded in the upper outer part of the substation wall to form two "thorny" walls, one long and one short.

[0082] The metal isolation sleeve can play a protective role and reduce the deformation of the steel nails during use.

[0083] When in use, the middle steel plate 1 is installed on the outer edge of the top of the wall by passing a steel nail through the opening on the middle steel plate 1 and embedding it into the wall.

[0084] For jumping animals such as cats and weasels, or when people want to climb up the wall, the upper triangular teeth 2 and the lower triangular teeth 3 are very sharp, which form resistance to them, making it impossible for them to cross the saw teeth to enter the substation, or the saw teeth directly penetrate and stab them.

[0085] The present invention records a new type of substation anti-small animal thorn device. When in use, steel nails are embedded in the upper outer part of the substation wall to form two "thorny" walls, one long and one short. This can effectively prevent small animals from climbing the wall to enter the substation, and can prevent people with ulterior motives from entering the substation and posing a threat to the power grid, with good protection effect.

[0093] The upper triangular teeth 2, the lower triangular teeth 3 and the middle steel plate 1 are all made of stainless steel.

[0094] The number of the upper triangular teeth 2 and the lower triangular teeth 3 is preferably fifty.

[0095] The lower triangular teeth 3 extend downward, and the sharp serrations act as a threat, forming the first line of defense to prevent it from climbing upward. If it breaks through the first line of defense and wants to continue climbing upward, it needs to grasp the upward traction point. The upper triangular teeth 2 are designed to be longer than the lower triangular teeth 3, which can effectively prevent it from finding the upward traction point, serving as the second line of defense to prevent it from entering the substation.
