Description

Technical Field

[0001] The invention relates to the technical field of mouse guards, and in particular to a rotatable mouse guard device. 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] Traditional methods of dealing with communication optical cables bitten by small animals: 1. Replace the damaged communication optical cables; 2. Passive repair, waste of manpower, material resources and time; 3. Repeated defects in the same area, low work efficiency; 4. High risk, difficult to implement and large impact of operations on live lines; 5. Cause unplanned communication interruptions in substations, offices and business offices;

[0004] Due to the constraints of laws, ecological protection and geographical environment, it is impossible to implement measures such as cutting down trees, poisoning and capturing to prevent rats in communication optical cable lines. Special communication optical cables in power systems cannot be prevented and controlled with metal sheathed communication optical cables. The reason is: the influence of electromagnetic induction electricity will cause harm to equipment, personnel and networks. Due to the constraints of the above factors, the current special communication optical cables in operation for power systems are facing the "difficult" problem of preventing small animals from biting them.

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

[0006] Since rodents have well-developed incisors that continue to grow, squirrels and mice have the habit of gnawing objects to keep their teeth sharp.

[0007] The polyethylene sheath material of the communication optical 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, the fiber core in use and the spare fiber core in the same loose tube of the operating optical fiber are interrupted on site, and the unused fiber core and tube 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.

[0010] Therefore, there is an urgent need for a mouse-blocking device for high-altitude optical cables to perform physical isolation to achieve a protective function. Summary of the invention

[0035] 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.

[0036] 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.

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.

[0038] 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.

[0039] Example 1

[0040] Reference Figure 1-2 , provides a rotatable rodent-proof baffle device, comprising:

[0041] ADSS optical cable 100;

[0042] The isolation parts 200 are installed at both ends of the ADSS optical cable 100. The ADSS optical cable 100 between the two isolation parts 200 forms an isolation section to prevent rodents from climbing and gnawing along the ends of the ADSS optical cable 100. The isolation parts 200 will rotate when encountering natural wind force to reduce wind resistance.

[0043] Specifically, the two ends of the ADSS optical cable 100 are fixed on the pole tower through hangers, and the two isolation parts 200 are rotatably installed on the outer sheaths of the two ends of the ADSS optical cable 100, so as to block small animals in the "non-wrapped" operation area, and isolate the ADSS optical cable 100 between the two isolation parts 200, so as to put on a "container" for the ADSS optical cable 100 in operation, which effectively prevents small animals from biting, fundamentally eliminates the occurrence of small animals biting communication optical cables, effectively prevents the occurrence of interruptions in the operation of services, and completely solves the problems of large number of small animal biting faults and difficult operation and maintenance of non-metallic communication optical cables for power.

[0044] Under the action of natural wind, the isolated part will rotate, and the rotation will disperse part of the wind resistance, which can reduce the damage of the swing amplitude of the shielding component to the ADSS optical cable 100;

[0045] The protection part 300 is disposed between the ADSS optical cable 100 and the isolation part 200, and is used to prevent the isolation part 200 from causing damage to the ADSS optical cable 100 during installation;

[0046] The protective part 300 is composed of a number of steel columns wrapped around the outside of the ADSS optical cable 100. The steel columns are arranged in a circular shape and fit the outer wall of the ADSS optical cable 100. Each steel column is twisted 720° along the axis of the ADSS optical cable 100. During installation, they are screwed into the outside of the ADSS optical cable 100 in turn to form an annular protective layer. The protective layer has a compressive resistance to reduce the pressure and wear on the ADSS optical cable 100 during the installation of the isolation part 200.

[0047] Specifically, the diameter of the steel column is 1 cm, and a rubber ring is covered on the surface of the steel column, thereby improving the protective effect.

[0048] The isolation part 200 includes a shielding component 201 . The shielding component 201 is installed on the outside of the protection part 300 through a rotating component 202 , and blades 203 are equidistantly installed on the outside of the shielding component 201 .

[0049] Specifically, the blade 203 is equipped with a repelling component, which includes a lens 204 and a bamboo whistle 205. The lens 204 is respectively installed on the outer side of the blade 203. When the lens 204 rotates, it will reflect light when exposed to sunlight and moonlight. If the reflected light suddenly shines on the eyes of the mice that come to destroy, the mice will be frightened, thereby achieving the effect of repelling. The bamboo whistle 205 must be no less than two and is installed on the outer side of the blade 203 by gluing or screwing. When the blade 203 rotates under the action of wind, the bamboo whistle 205 will enter the airflow, which will cause the airflow to vibrate and make a sound. Mice are relatively timid, and under the action of the sound, the mice dare not approach, thereby achieving the effect of anti-rat. This structure uses sound and light in combination to achieve the effect of repelling to the greatest extent.

[0050] The bamboo tip 205 is made of plastic, which is light and will not affect the overall rotation.

[0051] The shielding assembly 201 includes two semicircular baffles 201a, which are combined to form a disc-shaped structure, and the two semicircular baffles 201a are both provided with inner arc grooves 201b at the axis, and the two inner arc grooves 201b form installation notches 201c for enclosing the protective part 300.

[0052] Specifically, a connecting groove is provided on the horizontal side of one of the baffles 201a, and the length of the connecting groove is consistent with the thickness of the baffle 201a. A connecting protrusion is provided on the horizontal side of the other baffle 201a. When connecting, the two baffles 201a are connected from the side, and the connecting protrusion is inserted into the connecting groove to ensure the firmness of the connection.

[0053] Example 2

[0054] Reference Figure 4-6 , this embodiment is different from the first embodiment in that:

[0055] The rotating assembly 202 includes two C-shaped bars 202a, and fixing ears 202b are symmetrically arranged at both ends of the two C-shaped bars 202a.

[0056] Specifically, two C-shaped bars 202a surround the outside of the protective portion 300, and the fixing ears 202b are fastened by bolts to complete the outside of the C-shaped bars 202a.

[0057] A bearing member 202c rotatably connected to the shielding assembly 201 is installed on the outside of the C-shaped bar 202a.

[0058] The bearing member 202c includes two outer rings 202c-1 and two retaining frames 202c-2. The two outer rings 202c-1 are respectively fixed on the inner arc grooves 201b on the inner sides of the two baffles 201a, and slideways 202c-3 are arranged on the inner sides of the two outer rings 202c-1. The two retaining frames 202c-2 are respectively fixed on the outer sides of the two C-shaped bars 202a.

[0059] Specifically, the middle section of the retainer 202c-2 is provided with an arc-shaped convex strip fixed to the outside of the C-shaped strip 202a, and the retainer 202c-2 slides in the slideway 202c-3;

[0060] The two outer rings 202c-1 are combined to form a complete circle, so that the two slideways 202c-3 can be merged. During installation, the outer ring 202c-1 is sleeved on the outside of the retaining frame 202c-2, and a limiting protrusion is set on the outer side of the outer ring 202c-1. A connecting groove is opened on the inner side of the inner arc groove 201b. During installation, the connecting groove on the inner side of the baffle 201a is inserted into the limiting protrusion, and then the baffle 201a can be installed on the outer ring 202c-1. A connecting plate is installed on one side of the outer ring 202c-1, and a screw hole is opened on one side of the baffle 201a. The bolts are passed through the connecting plate and screwed into the screw holes to complete the fixation.

[0061] Two rows of slots 202c-4 are provided on the surface of the retaining frame 202c-2, and rollers 202c-5 are equidistantly arranged on the inner side of the slots 202c-4. The rollers 202c-5 are rotatably connected in the slots 202c-4 via the rotating shaft 202c-6. Since the retaining frame 202c-2 is fixed, the outer ring 202c-1 slides on the outer side of the rollers 202c-5. The outer ring 202c-1 is fixed on the baffle 201a. Therefore, under the action of wind, the blades 203 will be blown to drive the baffle 201a to rotate. The rotation will disperse part of the wind resistance, thereby reducing the damage of the swing of the shielding component to the ADSS optical cable.

[0062] The rest of the structure is the same as that of Example 1.

[0063] Example 3

[0064] Reference Figure 3 , this embodiment is different from the above embodiment in that:

[0065] Inertia components are disposed inside the two baffles 201 a to ensure the stability of the rotation by increasing the moment of inertia when the shielding assembly 201 rotates.

[0066] The inertial part includes dividing strips 201d equidistantly arranged inside the baffle 201a, and a dividing cavity 201e is formed between two adjacent dividing strips 201d. Steel balls 201f are placed in the dividing cavity 201e. During the rotation process, the steel balls 201f in the dividing cavity 201e at different positions will roll along the direction of the dividing cavity 201e under the force of gravity. Different steel balls 201f roll under the action of gravity, thereby increasing the overall torque. The increase in torque will increase the moment of inertia, thereby making the baffle 201a more stable when rotating.

[0067] The rest of the structure is the same as that of Example 2.
