Description

Technical Field

[0001] The invention relates to the technical field of rat-proof sleeves, and in particular to an open type rat-proof sleeve. Background Art

[0002] In the construction of power communication optical cables in the power industry, the laying method of each communication optical cable line is different according to the different geographical locations of power plants, substations, dispatching agencies, power supply stations, and business offices. The usual practice is to use existing power poles, pipelines, and tunnel resources to lay power communication optical cables on the same poles and trenches. Due to the overhead laying method of power communication optical cables, when the optical cables pass through densely forested areas, failures and defects in the operating communication optical cables often occur in March and November every year due to small animals gnawing, resulting in interruptions in production real-time control services, thereby causing power accidents caused by communication interruptions;

[0003] Due to the constraints of national ecological protection policies, laws, ecological protection and geographical environment, it is impossible to implement measures such as tree cutting, poisoning and capturing to prevent rats in communication optical cable lines, and it is also impossible to use metal sheathed communication optical cables for special communication optical cables in power systems. The reason is: the influence of electromagnetic induction electricity will cause harm to equipment, personnel and networks;

[0004] Due to the constraints of the above factors, there is a "long-standing" problem in preventing small animals from gnawing on the current special power communication optical cables in operation, especially the section of the optical cable connecting the junction box. This section of the optical cable runs vertically along the tower. Rats can climb through the tower and gnaw the optical cable there, causing interruption of real-time production control services, thereby triggering power accidents caused by communication interruptions. Therefore, there is an urgent need for a rodent-proof casing to solve this problem.

[0005] Reasons why rodents chew on in-service communication optical cables:

[0006] Since the incisors of rodents are well developed and continue to grow, squirrels and mice have the habit of chewing objects to keep their teeth sharp;

[0007] The polyethylene sheath material of the communication cable sheath has a special smell and is often gnawed by squirrels and mice;

[0008] The optical waves of optical fiber transmission equipment in communication optical cables are usually 1310nm and 1550nm, which belong to the near infrared 700-2500nm non-visible light in the infrared frequency band. In my opinion, the eyes of squirrels and mice can see the light waves or thermal radiation transmitted in the optical fiber. Reason: Every time a rodent bites off an optical fiber in operation in a communication optical cable, the fiber core in use and the spare fiber core in the same loose sleeve of the operating optical fiber are interrupted on site, and the unused fiber core and sleeve in the bitten gap of the faulty optical cable are intact;

[0009] Judging from the annual operation and maintenance schedule of communication optical cables, the peak periods for rodent infestation are March and October each year. Rats shed their fur in spring and autumn every year, and the situation of them gnawing on the operating communication optical cables is closely related to their physiological cycle. Summary of the invention

[0010] In view of the problems existing in the above-mentioned existing open-type rodent-proof sleeve, the present invention is proposed.

[0011] Therefore, the object of the present invention is to provide an open type rodent-proof sleeve.

[0015] The matching installation part is used as an auxiliary tool to quickly put the sheath part on the outside of the optical cable.

[0016] As a preferred solution of the open type rodent-proof sleeve of the present invention, the sheath part includes a coil spring sleeve, which is formed by rolling up by a plate rolling machine. After rolling up, one side of the coil spring sleeve is overlapped on top of the other side to form a fitting seal.

[0017] As a preferred solution of the open type rodent-proof sleeve of the present invention, the edges of both sides of the coil spring sleeve are equidistantly provided with partition grooves, and the surface of the coil spring sleeve is equidistantly provided with collapse grooves, and a plurality of the collapse grooves provide contraction and expansion for the bending of the coil spring sleeve.

[0018] As a preferred solution of the open type rodent-proof sleeve of the present invention, the length of the collapse groove is 1 / 3 of the width of the coil spring sleeve, and the collapse groove is symmetrically opened on both sides of the center line of the coil spring sleeve.

[0019] As a preferred solution of the open type rodent-proof casing of the present invention, the matching installation part comprises a linear tube, and the through hole at the axis of the linear tube forms a wire groove for the optical cable to pass through.

[0020] As a preferred solution of the open-type rodent-proof sleeve of the present invention, an extruded tube is arranged at the bottom of the linear tube, and the extruded tube and the linear tube are integrally formed by injection molding.

[0021] As a preferred solution of the open type rodent-proof sleeve of the present invention, the angle between the extruded tube and the linear tube is 45°, and the weld seam between the extruded tube and the linear tube forms an oblique guide groove.

[0023] As a preferred solution of the open-type rodent-proof sleeve of the present invention, the linear tube adopts a split structure, and its dividing line is vertically cut along the axis of the linear tube to form two symmetrical shells, which are hinged by a transition piece.

[0025] Beneficial effects of the present invention: The sheath part of the present invention is similar to "armor" worn on the outside of the communication optical cable, so that the power communication optical cable is "physically isolated" from the outside world, avoiding damage by the gnawing of small animals, thereby preventing the occurrence of accidents caused by small animals gnawing on the power communication optical cable in operation, and has a better effect in preventing and controlling small animal gnawing or external force damage.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0038] Example 1

[0039] Reference Figure 1-4 , provides an open type rodent-proof casing, comprising:

[0040] Optical cable 100;

[0041] The sheath part 200 is covered on the outside of the optical cable 100 to form a protective layer to prevent rodents from gnawing and damaging the optical cable;

[0042] Furthermore, the sheath part 200 includes a coil spring sleeve 201, which is formed by rolling up by a plate rolling machine. After rolling up, one side of the coil spring sleeve 201 is placed on top of the other side to form a fitting seal.

[0043] Specifically, during installation, the open side of one end of the coil spring sleeve 201 is attached to the bottom of the optical cable 100 and pressed hard to deform the inner side of the coil spring sleeve 201 inward, thereby forming a gap between the inner side and the outer side. At this time, the optical cable 100 will enter the coil spring sleeve 201 along the gap, and then be safely wrapped around the inner side of the coil spring sleeve 201 in sequence from front to back until the installation is completed. This structure is similar to "armor" worn on the outside of the communication optical cable, so that the power communication optical cable 100 is "physically isolated" from the outside world, avoiding damage caused by small animals, thereby preventing accidents caused by small animals gnawing on the power communication optical cable 100 in operation, and has a better effect in preventing and controlling small animal gnawing or external force damage.

[0044] Furthermore, the edges of both sides of the coil spring sleeve 201 are equidistantly provided with separation grooves. The separation grooves 202 can reduce the bonding area of ​​the bonding surface, reduce the overall strength, and facilitate the separation of the openings. The surface of the coil spring sleeve 201 is equidistantly provided with collapse grooves 203. Several collapse grooves 203 provide contraction and expansion for the coil spring sleeve 201 to bend.

[0045] Specifically, the optical cable 100 will bend when it is connected to the junction box, and the coil spring sleeve 201 will bend synchronously. The contraction and expansion generated during the bending are borne by the collapse groove 203, thereby causing the coil spring sleeve 201 to deform, thereby satisfying the different bending directions of the optical cable 100 and having high practicality.

[0046] The length of the collapse groove 203 is 1 / 3 of the width of the coil spring sleeve 201, and the collapse groove 203 is symmetrically opened on both sides of the center line of the coil spring sleeve 201, and the distance between two adjacent collapse grooves 203 is 1.5 cm. This length and distance can maximize the curvature without causing the coil spring sleeve 201 to loosen.

[0047] Specifically, the coil spring sleeve 201 includes a strip plate 201a, the outside of the strip plate 201a is covered with a thermoplastic sleeve 201b, the strip plate 201a is made of stainless steel, the thermoplastic sleeve 201b is sleeved on the outside of the strip plate 201a, and then the strip plate 201a is completely wrapped by thermoplasticization with a hot air gun, and the wrapped strip plate 201a is formed into the coil spring sleeve 201 by a plate rolling machine. The wrapping with the thermoplastic sleeve 201b can play an insulating effect, reduce unnecessary safety hazards, and prevent the induction electricity of the primary power transmission line from injuring people;

[0048] Both ends of the strip plate 201a are provided with bevels. The bevels are set so that after the strip plate 201a is rolled up by the plate rolling machine, the fitting surfaces at both ends form an offset. The offset can facilitate the opening of the coil spring sleeve 201, and then facilitate the removal of the coil spring sleeve 201 from the optical cable 100, so as to facilitate recycling and reuse and reduce cost waste.

[0049] Both ends of the overlapping sides of the coil spring sleeve 201 are provided with notches 204 , which serve as bifurcations. When squeezed by external force, the overlapping parts of the coil spring sleeve 201 are separated to form openings.

[0050] Example 2

[0051] Reference Figure 5 The difference between this embodiment and the first embodiment is that the open type rodent-proof sleeve of this embodiment also includes:

[0052] The matching installation part 300 is used as an auxiliary tool to quickly cover the sheath part 200 on the outside of the optical cable 100.

[0053] The matching installation part 300 includes a linear tube 301 , and a through hole at the axis center of the linear tube 301 forms a wire groove 302 for the optical cable 100 to pass through.

[0054] Furthermore, an extruded tube 303 is provided at the bottom of the linear tube 301 , and the extruded tube 303 and the linear tube 301 are integrally formed by injection molding, and the integral molding has higher stability and longer service life.

[0055] Specifically, the angle between the extruded tube 303 and the linear tube 301 is 45°, the weld between the extruded tube 303 and the linear tube 301 forms an oblique guide groove 304, and the end of the extruded tube 303 is an arc-shaped structure, which can reduce the friction coefficient when inserted into the coil spring sleeve 201, making it more convenient to use;

[0056] A split piece 305 is provided at the tail angle between the extrusion tube 303 and the guide groove 304, and the split side of the split piece 305 is in a triangular structure;

[0057] During installation, pass the optical cable 100 through the cable trough 302, hold the matching installation part 300 with one hand, and hold the spring tube 201 with the other hand, align one end of the spring tube 201 with the tail end of the extrusion tube 303, and on the premise of keeping the spring tube 201 stationary, pull the matching installation part 300 to move linearly along the optical cable 100. During the movement, the extrusion tube 303 will enter from the end of the spring tube 201. At this time, the split piece 305 is aligned with the notch 204. The notch 204 is separated by the extrusion force, so that an opening is "torn" from the end of the spring tube 201. As the matching installation part 300 is continuously driven to move, the opening will be opened under the action of the extrusion tube 303. It becomes larger and larger, forming a channel for the guide groove 304 to pass through, and the opening slides upward with the guide groove 304 until it is separated from the guide groove 304 and then it will re-form the reset and encirclement action. Since the outlet of the guide groove 304 is higher than the optical cable 100, the opening will wrap the optical cable 100 when it is out of the guide groove 304 and encircles. As the matching installation part 300 moves linearly along the optical cable 100 for a longer distance, the reed tube 201 will cover more and more optical cables 100, until all the reed tubes 201 are covered on the optical cable 100 to complete the installation. This structure makes the reed tube 201 more convenient and efficient during installation, without the need for the cooperation of multiple people, only one person is needed, effectively reducing the installation cost.

[0058] The rest of the structure is the same as that of Example 1.

[0059] Example 3

[0060] Reference Figure 6 This embodiment is different from the above embodiments in that the linear tube 301 of this embodiment adopts a split structure, and its dividing line is vertically cut along the axis of the linear tube 301 to form two symmetrical shells, and the two shells are hinged by a transition piece 306.

[0061] The adapter 306 includes a bar block 306a fixed to the upper surface of one of the shells and an adapter seat 306b fixed to the upper surface of the other shell. A connecting block 306c is fixed to one end of the bar block 306a. A rotating rod 306d is provided through the axis of the adapter seat 306b. One end of the rotating rod 306d is fixed to one side of the connecting block 306c, and a lock is provided at the other end of the rotating rod 306d.

[0062] Specifically, fins are fixed on the outside of the two shells. By pressing the fins by hand, the two shells can be rotated and opened along the rotating rod 306d. After the shells are opened, they can be clamped on the outside of the optical cable 100. At this time, the optical cable can still be used even if both ends have been installed and fixed. The optical cable 100 does not need to be disassembled and inserted from the end. This structure does not require interruption of the running equipment and can be installed on site with power on, which has the advantages of convenient and efficient installation.

[0063] Specifically, the lock includes a conical structured clamp 306e, a conical surface of the clamp 306e is provided with a cross groove 306f, the cross groove 306f divides the clamp 306e into four claws 306g, when the rotating rod 306d passes through the adapter seat 306b, it is affected by the size of the hole of the adapter seat 306b, the claw 306g is forced to compress the cross groove 306f inward, after the claw 306g passes through the hole of the adapter seat 306b, it is not squeezed, and can play an anti-slip function.

[0064] The rest of the structure is the same as that of Example 2.
