Description

Anti-slip device for protective equipment

[0001] The present invention relates to a slip prevention device for a protective pipe for preventing slipping of an insulating protective pipe placed on a power line to prevent line failure, electric shock, or power outage accidents caused by contact with foreign objects such as construction site workers or equipment during tree pruning work or indirect live line work or during construction around a power line, and more specifically, to a slip prevention device for a protective pipe for a distribution line that can prevent leakage current by preventing foreign objects such as birds or rats from entering or birds from building nests in an insulating protective pipe or a connecting pipe connecting two protective pipes, and that can be easily and safely installed on a power line using a smart stick.

[0002] Power lines, such as transmission lines and distribution lines, which are generally used to transmit electricity, play a role in safely transmitting electricity from substations in the suburbs of cities to consumers who use electricity, such as homes, buildings, and factories, and are mainly installed on towers or utility poles.

[0003] In areas with dense forests such as mountainous regions or roads lined with trees, these power lines can frequently cause power outages, wiring failures, and equipment breakdowns when they come into contact with trees that have grown, which can result in excessive maintenance and management costs.

[0004] Meanwhile, there is a risk of contact between workers or equipment when working on live lines or working near electrical equipment while high voltage electricity is flowing through the power lines.

[0005] In addition, if power lines are installed close to a building, damage such as line failure due to contact with external objects or impact during construction or electric shock due to worker negligence may occur.

[0006] In order to prevent accidents to workers and equipment failures due to contact with external objects, protective pipes (insulated protective equipment) that cover and insulate a portion of the power line are widely used. Depending on the on-site conditions and circumstances, these can be installed in series by connecting multiple pieces to the desired length using separate connecting pipes for fastening.

[0007] However, if a protective tube is installed only in a part of the power line, the protective tube is often pushed down along the power line from the set position due to external forces such as the sagging of the power line, wind, or its own weight. This causes the power line to be exposed, significantly increasing the risk of safety accidents such as electric shock.

[0008] Meanwhile, if foreign objects such as birds or rats enter the protective pipe or connecting pipe, or if birds build a nest, the air space distance and creeping distance become shorter, and if rainwater infiltrates the inside, there is a very high risk of electric shock due to leakage current that flows directly downward through the rainwater as a passageway. In addition, there is a problem that the insulation, that is, the insulation strength due to air insulation, gradually decreases due to stress such as deterioration and deformation, which causes insulation failure and insulation breakdown.

[0009] In addition, there is a problem that when snakes or rats climb up the power poles to eat eggs or chicks in bird nests inside the protective pipes or connecting pipes, they come into contact with power facilities including high-voltage power lines, which frequently causes various accidents such as short circuits, electric leakage, and power outages.

[0010] Meanwhile, when workers ride a live-line work vehicle and perform various distribution work such as inspection, maintenance, and relocation (replacement) of overhead distribution lines, direct live-line work done by hand while power is supplied without interruption carries a high risk of accidents such as electric shock. Therefore, indirect live-line work is currently being widely implemented, which uses an insulating smart stick (insulating stick) to ensure safety by allowing workers to perform work without touching the live line with their hands even when the line is live.

[0011] The background technology or prior art described herein is information that the inventor possesses or acquired in the process of deriving and completing the present invention, and is only stated to be helpful in understanding the technical significance of the present invention and useful in prior art research and examination, and does not mean technology that is generally known and widely used in the technical field to which the present invention belongs prior to the application for the present invention.

[0012] Accordingly, the inventor of the present invention has comprehensively considered all the above-mentioned matters and, at the same time, has made great efforts to develop a novel anti-slip device for a protective pipe, which can be firmly fixed to a power line by turning and tightening a screw spindle to prevent the protective pipe from slipping down along the power line from a set position due to external forces such as sagging of the power line, wind, and the self-weight of the protective pipe, and can also prevent foreign objects such as birds or rats from entering the protective pipe or a connecting pipe for connecting two protective pipes in a single line, or birds from building nests therein, thereby maintaining high electrical insulation properties and preventing leakage current, and furthermore, can be easily and safely installed on a power line using a smart stick during indirect live line work. As a result of this, the inventor has devised and continuously researched to develop a novel anti-slip device for a protective pipe, which can be easily and safely installed on a power line using a smart stick during indirect live line work.

[0013] Therefore, the technical problem and purpose to be solved by the present invention is to provide a barrier pipe anti-slip device that can prevent foreign substances such as birds or rats from entering the barrier pipe or connecting pipe.

[0014] The technical problem and purpose of the present invention is to provide an anti-slip device for a protective pipe that can be easily and safely installed on a power line using a smart stick.

[0015] The technical problems and objectives to be solved by the present invention are not limited to the technical problems and objectives mentioned above, and other technical problems and objectives not mentioned will be clearly understood by those skilled in the art to which the present invention pertains from the description below.

[0016] In order to effectively achieve a specific technical purpose while embodying a new idea for solving the technical problem of the present invention as described above, a specific means according to an embodiment of the present invention is a slip prevention device for a protective pipe, which is installed on a power line so as to be in contact with both ends of the protective pipe covered to protect the power line and prevents the protective pipe from slipping, characterized in that it includes a body formed by protruding to one side at the upper end of a vertically long guide and a horizontal arm having a screw hole at the lower end of the guide protruding to one side, a movable jaw that is mounted so as to be able to rise and fall along the guide between the fixed jaw and the horizontal arm and tightens and clamps the power line as the distance between the fixed jaw and the horizontal arm decreases, and a screw spindle in which the movable jaw is fixed to the upper end, the upper end is screwed into the screw hole of the body, and opens and closes the movable jaw so as to decrease or increase the distance between the fixed jaw and the horizontal arm depending on the direction of rotation, thereby tightening or loosening the power line. Present.

[0017] Accordingly, the present invention can prevent the phenomenon of the protective tube being pushed down along the power line from the set position due to external forces such as sagging of the power line, wind, or the self-weight of the protective tube by firmly fixing the protective tube by turning and tightening the screw spindle when installing it on the power line so that both ends of the protective tube are in contact with each other.

[0018] In addition, a preferred embodiment (aspect) of the present invention further comprises a plate-shaped cover that is fixed to one side of the movable body and is in contact with both ends of the protective tube to block a gap with the power line to prevent foreign matter such as birds or rats from entering the inside of the protective tube, thereby reliably preventing foreign matter such as birds or rats from entering the protective tube or snakes or rats climbing up the power pole to eat eggs or young birds nesting in the protective tube.

[0019] In addition, as a preferred embodiment (aspect) of the present invention, the cover has an interference prevention groove formed on the upper surface in the same shape as the upper surface of the movable body to prevent the lifting operation of the movable body from being interrupted due to contact interference with the power line and getting caught, and a plurality of ventilation holes are arranged and formed to dissipate heat inside the protective tube, so that the cover can naturally raise and lower simultaneously with the movable body according to the rotation operation of the screw spindle, and reliably block the gap between the protective tube and the power line, thereby preventing foreign substances such as birds or rats from entering the inside of the protective tube, and also can efficiently dissipate heat generated inside the protective tube by allowing smooth ventilation.

[0020] In addition, a preferred embodiment (aspect) of the present invention further comprises a connecting pipe for installing multiple protective pipes in a row by covering the ends of the protective pipes arranged in a row on the power line by opening a first opening formed long in the middle of the lower portion and spreading it out on both sides, and a second opening formed long in the middle of the lower portion and spreading it out on both sides for inserting a power line, and a closing pipe inserted into the inside of the connecting pipe located at one end of the protective pipe to prevent foreign substances such as birds or rats from entering the inside of the connecting pipe through the first opening, thereby reliably preventing birds or rats from entering the connecting pipe or snakes or rats from climbing up the utility pole to eat eggs or chicks of the bird's nest in the connecting pipe.

[0021] In addition, as a preferred embodiment of the present invention, a first ring for hanging a hook of a smart stick is formed on one side of the body, and a second ring for hanging a hook of a smart stick is formed on the lower end of the screw spindle, thereby improving convenience and ease of live work.

[0022] In addition, as a preferred embodiment of the present invention, a handle for holding and turning the screw spindle by hand is provided at the bottom of the screw spindle, thereby increasing the ease and convenience of installation work.

[0023] In addition, as a preferred embodiment (aspect) of the present invention, a first wire groove for inserting and biting a power line having an outer diameter of 6 mm or more is formed on one side of the movable body facing the fixed body, and a second wire groove for inserting and biting a power line having an outer diameter of less than 6 mm is formed on the other side, so that it can be universally used for power lines of various sizes and specifications, thereby maximizing convenience of work.

[0024] According to an embodiment that implements the technical idea on which the unique solution is based in order to solve the technical problem of the present invention, when installing a protective tube to protect a power line, it is firmly fixed by applying pressure by turning and tightening a screw spindle so that both ends of the protective tube are in contact with each other on the power line, thereby preventing the protective tube from slipping down along the power line from the set position due to external forces such as sagging of the power line, wind, or the self-weight of the protective tube.

[0025] In addition, when installed on a power line, the cover is in contact with both ends of the protective pipe and securely blocks the gap with the power line, so it can prevent foreign objects such as birds or rats from entering the protective pipe or snakes or rats from climbing up the pole to eat the eggs or babies of birds that have built a nest in the protective pipe. In addition, by maintaining the insulation space and creeping distance of the protective pipe, it can stably exhibit air insulation performance by allowing smooth circulation of air within the protective pipe.

[0026] Therefore, not only can the insulation strength of the protective pipe be improved, but also high electrical insulation can be maintained by insulating and blocking the leakage current of the power line flowing in the direct direction through the passage of rainwater or moisture that penetrates into the inside of the protective pipe.

[0027] In addition, it can prevent electric shock accidents caused by leakage current, as well as insulation failure caused by stress such as deterioration and deformation of the protective tube.

[0028] Moreover, since the connecting pipe that connects two protective pipes in a row has a closed pipe inserted inside the connecting pipe located at one end of the protective pipe, it can prevent foreign objects such as birds or rats from entering the connecting pipe or snakes or rats from climbing up the pole to eat the eggs or babies of birds that have built a nest in the connecting pipe.

[0029] In addition, it can be universally used for power lines of various sizes through the first and second wire grooves of the movable joint regardless of the cross-sectional area, thickness, or specifications of the power line, thereby improving the convenience of installation work.

[0030] In other words, since it can be universally applied to power lines of various thicknesses and specifications using a single anti-slip device, it maximizes convenience and efficiency of use, as well as functionality and usability, and thereby enhances marketability through economic feasibility and product differentiation, thereby promoting convenience in use.

For example, the upper side in a drawing may be named or referred to as the upper side and the lower side as the lower side, and the length direction may be named or referred to as the front / back direction, and the width direction may be named or referred to as the left / right direction.

[0047] Additionally, the terms first, second, etc. used in the present invention can be used to describe various components. That is, the terms first, second, etc. can be used only for the purpose of distinguishing one component from another.

[0048] An anti-slip device (1) for a protective pipe according to an embodiment of the present invention is fixedly installed by turning a tightening screw on the power line (L) so that both ends of the protective pipe (P) covered to protect the power line (L) are in contact with each other, thereby preventing the protective pipe (P) from slipping. The main components constituting the device include a body (10), a movable member (20), a screw spindle (30), and a cover (40), as illustrated in FIGS. 1 to 4.

[0049] The body (10) is formed with a vertically long guide (11), and a hook-shaped fixing member (12) is formed to protrude forward at the top of the guide (11), and a horizontal arm (13) having a screw hole (14) drilled vertically in the center portion is formed to protrude forward at the bottom of the guide (11).

[0050] That is, the body (10) is formed as a T-shaped or C-shaped frame when viewed from the side.

[0051] In particular, the lower surface of the fixed member (12) is formed to be tightly wrapped around a part of the power line (L).

[0052] That is, the fixed member (12) is bent or concave in an arch shape or a ∧ shape with the center part concave inward when viewed from the side in order to stably adhere to the upper circumference of the power line (L) whose cross-section is circular.

[0053] And on the other side (opposite side) of the guide (11), i.e., the rear side, a ring-shaped first ring (15) is integrally formed for easily hanging the hook of the smart stick or holding it with a pair of tongs when performing indirect live-line work.

[0054] The movable member (20) is mounted so as to be able to move up and down along the guide (11) between the fixed member (12) and the horizontal arm (13).

[0055] And the upper surface of the movable member (20) is formed symmetrically with the lower surface of the fixed member (12) so as to be tightly wrapped around a part of the power line (L).

[0056] That is, the movable member (20) is bent or concave in an arched shape or a ∨ shape with the center part concave inward when viewed from the side in order to stably adhere to the lower circumference of the power line (L) whose cross-section is circular.

[0057] Additionally, a guide groove (23) is formed on the rear of the movable member (20) to minimize friction acting on the contact surface when it contacts the surface of the guide (11) and performs a sliding motion.

[0058] And, on the lower surface of the movable member (20), a vertical hole is drilled for inserting the upper part of the screw spindle (30), and on one side, a horizontal hole is drilled that intersects the vertical hole vertically and has a female thread cut into it so that a bolt or small screw can be inserted and tightened.

[0059] This movable member (20) is gradually raised along the guide (11) in the direction in which the worker turns the screw spindle (30) and the distance between it and the fixed member (12) is shortened, thereby clamping the power line (L) by applying pressure.

[0060] The screw spindle (30) is screw-connected to the screw hole (14) of the body (10) so that it can be raised and lowered while rotating in the direction of rotation, and a movable member (20) is fixed to the top.

[0061] And, at the bottom of the screw spindle (30), a handle (31) is attached in a detachable manner so that the worker can hold it with his / her hand and turn it easily and conveniently, and at the bottom, a second ring (32) is drilled so that the hook of the smart stick can be easily hung and turned when performing indirect live-line work.

[0062] In addition, an end tip (33) that fits into the lower surface of the movable member (20) is formed on the upper end of the screw spindle (30), and a lock groove (34) into which a lock (headless bolt) or key for fixing the movable member (20) is fitted is formed around the end tip (33).

[0063] That is, the screw spindle (30) can be fixed to the movable member (20) by inserting a bolt or small screw into a horizontal hole with a female thread cut into one side of the movable member (20) so that the end tip (33) thereof is inserted into a vertical hole drilled into the lower surface of the movable member (20) so that the vertical hole and the screw thread intersect each other vertically, and then tightening the screw.

[0064] These screw spindles (30) open and close to bring the distance between the movable member (20) and the fixed member (12) closer or farther apart depending on the direction in which the worker turns them, thereby tightening or loosening the power line (L) and releasing it.

[0065] The cover (40) is formed in a plate shape and is fixed to one side of the movable body (20).

[0066] That is, the cover (40) is in contact with both ends of the protective tube (P) to prevent foreign objects such as birds, rats, and snakes from entering the inside of the protective tube (P) and blocks the gap with the power line (L).

[0067] And on the side of the cover (40), a plurality of ventilation holes (41) are formed in an array to naturally dissipate heat within the protective tube (P).

[0068] That is, there are many small hole-shaped ventilation holes (41) on the inside of the side of the cover (40).

[0069] In addition, an interference prevention groove (42) having the same shape as the upper surface of the movable body (20) is formed on the upper surface of the cover (40) to prevent the occurrence of a malfunction due to interference with contact with the power line (L) and catching when the movable body (20) is raised simultaneously.

[0070] That is, the interference prevention groove (42) of the cover (40) is bent or concave in an arched shape or a ∨ shape with the center part sunken inward when viewed from the side in order to stably adhere to the lower perimeter of the power line (L) having a circular cross-section.

[0071] Meanwhile, a first opening (51) is formed long in the center of the lower part of the protective tube (P) so that it can be easily spread to both sides and wrapped around the power line (L).

[0072] In addition, the protective tube (P) is configured and structured to be elastically opened when an external force is applied so that it can flexibly and naturally wrap around the power line (L), and to return to its original shape when the external force is removed.

[0073] The main actions, operating principles, and functions of the protective barrier anti-slip device (1) according to the embodiment of the present invention configured as described above are as follows.

[0074] First, when installing the power line (L) so that it is in contact with both ends of the protective tube (P) that is covered to protect the power line (L), it can be easily and firmly fixed by turning and tightening the screw spindle (30).

[0075] That is, when the worker turns the screw spindle (30) in the loosening direction using the handle (31), the screw spindle (30) is screw-connected by the cross arm (13) and the screw hole (14) of the body (10), so that the movable member (20) descends and the gap between the fixed member (12) of the body (10) widens, and in this state, when the fixed member (12) of the body (10) is hung on the power line (L) using the smart stick so that it comes into contact with both ends of the protective tube (P) and the screw spindle (30) is turned in the opposite (locking) direction, the movable member (20) rises and gradually pressurizes the power line (L), so that it can be firmly fixed.

[0076] In this way, by maintaining the body (10) fixed to the power line (L) while in contact with both ends of the protection pipe (P), it is possible to prevent the protection pipe (P) from being pushed down along the power line (L) from the set position by external forces such as a dip, which is the length downward from the horizontal line connecting the support points of the power line (L), wind, and the self-weight of the protection pipe (P).

[0077] In addition, during the process of installing on the power line (L), the cover (40) rises simultaneously with the movable member (20) to prevent foreign substances from entering the inside of the protective pipe (P), and this reliably prevents birds or rats from entering the protective pipe (P) or snakes or rats from climbing up the electric pole to eat eggs or young birds in the bird nest inside the protective pipe (P), thereby maintaining the air space distance and creeping distance, and stably exhibiting air insulation performance by allowing smooth circulation of air inside the protective pipe (P).

[0078] The main elements constituting the anti-slip device (1) for a protective tube according to another embodiment of the present invention include a body (10), a movable member (20), a screw spindle (30), a cover (40), a connecting pipe (50), and a closing pipe (60), as shown in FIGS. 5 and 6.

[0079] The connecting pipe (50) serves to connect two adjacent protective pipes (P) in a single line.

[0080] And, in the lower center part of the connecting pipe (50), a first opening (51) is formed lengthwise along the length direction to serve as an entrance and exit, divided into front and rear sides to cover the ends of the left and right protective pipes (P).

[0081] That is, the connecting pipe (50) is formed as a hollow tube with an inner diameter slightly larger than the outer diameter of the protective pipe (P) to prevent movement by wrapping around the opposite ends of the protective pipes (P) arranged in a row on the power line (L) by spreading the first opening (51) to both sides, and the hollow shape of the cross-section is formed to correspond to the outer circumferential shape of the protective pipe (P).

[0082] Here, the connecting pipe (50) can be formed by molding with a material such as a polymer insulating material, a soft synthetic resin, or synthetic rubber having a certain length and elasticity so that it can be flexibly and naturally wrapped around the protective pipe (P) when an external force is applied and can be retracted to its original state when the external force is removed.

[0083] For example, the connecting pipe (50) may be formed by molding one or a mixture of polyethylene, polyurethane, non-crosslinked polypropylene, polyisocyanurate, polyamideimide, and fluororesin.

[0084] The closed pipe (60) serves to prevent foreign substances such as birds or rats from entering the internal space where the protective pipe (P) of the connecting pipe (50) is not fitted through the first opening (51) of the connecting pipe (50).

[0085] And, in the lower central part of the closed pipe (60), a second opening (61) is formed long to cover the power line (L).

[0086] That is, the closed pipe (60) is inserted into the inside of the connecting pipe (50) located at one end of the protective pipe (P) in a closed state by spreading the second opening (61) to both sides and covering the power line (L).

[0087] Meanwhile, it is preferable that the cross-sectional shape of the closed pipe (60) be formed in the same shape as the cross-sectional shape of the protective pipe (P).

[0088] According to another embodiment of the present invention, the anti-slip device (1) for a protective tube configured as described above can more reliably prevent foreign substances such as birds or rats from entering the connecting tube (50) or birds from building nests, thereby maintaining an air space distance and a creeping distance, thereby stably demonstrating air insulation performance through smooth circulation of air within the protective tube (P).

[0089] Among the components related to the anti-slip device (1) for a protective tube according to another embodiment of the present invention, components having the same or similar operational effects as the above-described embodiment use the same reference numerals, and repetitive and specific descriptions thereof are omitted.

[0090] Meanwhile, the main elements constituting the anti-slip device (2) for a protective tube according to another embodiment of the present invention include a body (10), a movable member (20), and a screw spindle (30) as shown in FIGS. 7 and 8.

[0091] In particular, on one side of the upper surface of the movable member (20), that is, the surface facing the fixed member (12) of the body (10), a first wire groove (21) in the shape of an arc is formed for inserting and biting a power line (L) having an outer diameter of 6 mm or more, such as a covered wire, and on the other side, a second wire groove (22) is formed for inserting and biting a power line (L) having an outer diameter of less than 6 mm, such as a bare wire.

[0092] Therefore, regardless of the cross-sectional thickness or specification of the power line (L), it can be universally used for power lines (L) of various sizes through the first and second wire grooves (21) (22) of the movable member (20), thereby improving the convenience and ease of installation work.

[0093] Among the components related to the anti-slip device (2) for a protective tube according to another embodiment of the present invention, components having the same or similar operational effects as the above-described embodiment use the same reference numerals, and repetitive and specific descriptions thereof are omitted.

[0094] Meanwhile, the present invention is not limited to the above-described embodiment and the attached drawings, and can be variously modified and applied in various ways not illustrated within the scope that does not depart from the technical spirit of the present invention, and it is obvious to a person having ordinary skill in the art to which the present invention pertains that it can be widely applied by replacing each component and changing it to an equivalent other embodiment.

[0095] Therefore, the contents related to modifying and applying the technical features of the present invention should be interpreted as being included within the technical idea and scope of the present invention.

[0096] The slip prevention device for a protective pipe according to an embodiment of the present invention has industrial applicability as a slip prevention device that prevents the protective pipe from being pushed down along the power line from a set position due to external forces such as the dip of the power line, wind, or its own weight by installing it on the power line so that both ends of the insulating protective pipe that covers the power line are in contact with each other to prevent line failure, electric shock, or power outage accidents caused by contact with external objects such as construction site workers or equipment during tree pruning work or indirect live line work or during construction around the power line.
