Description

Technical Field

[0001] The utility model relates to the technical field of anti-bird thorn devices, in particular to a retractable anti-bird thorn with a locking device. Background Technique

[0002] With the continuous development of China's power system, power facilities such as overhead transmission lines and substations have been gradually improved and have a wider coverage. In sparsely populated areas, bird activities are relatively frequent. Many birds use iron towers, substations, etc. as habitats, and foreign objects such as bird nests and bird droppings interfere with the normal operation of power facilities, thus causing failures.

[0003] Traditional anti-bird thorns are mostly hand-broken anti-bird thorns. After installation, the installers need to break the thorns one by one. It is easy to cause uneven breaking angles due to human factors, which in turn leads to inconsistent protection areas. Moreover, the breaking process takes time, and the anti-corrosion coating on the outer layer of the thorns is easily damaged when the thorns are bent. To improve these problems, the Chinese patent document "202221732722.2" discloses a retractable anti-bird thorn, in which multiple anti-bird thorns are movably arranged on the thorn base, and then the thorn retraction and extension sleeve is sleeved on the multiple anti-bird thorns, so that the anti-bird thorns can be inclined and spread or erected and retracted. However, when the anti-bird thorn is used on an inclined surface, some anti-bird thorns will retract due to the action of gravity and cannot be normally opened, resulting in a reduced protection area. Content of the Utility Model

Detailed implementation manners

[0027] The technical solution of the present utility model will be further elaborated in detail below in conjunction with specific embodiments. For parts that are not detailedly recorded and disclosed in the following embodiments of the present utility model, they should all be understood as the prior art known or should be known to those skilled in the art, such as the material and specific structure of the anti-bird thorn 5, etc.

[0028] A retractable anti-bird thorn with a locking device, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 shown, includes: a needle disk base, a needle disk retractable member 4, and multiple anti-bird thorns 5 movably arranged on the needle base. The needle disk retractable member 4 is sleeved on all the anti-bird thorns 5, and the needle disk retractable member 4 moves along the vertical direction of the needle disk base to make all the anti-bird thorns 5 in a retracted state or a dispersed state. Multiple groups of shape adjustment channels 13 are also arranged on the needle disk retractable member 4, and at least one anti-bird thorn 5 passes through the shape adjustment channels 13. In this way, the movement range of the anti-bird thorn 5 will be restricted by the shape adjustment channels 13, and the anti-bird thorn 5 will not be retracted under the action of gravity due to being arranged on an inclined plane, thus solving the problem of the reduction of the protection area caused by the retraction of the anti-bird thorn 5, and further being able to fully ensure that the shape of the anti-bird thorn 5 meets the requirements. Due to the inclined plane, the anti-bird thorn 5 is retracted. In order to ensure that the anti-bird thorns 5 can be evenly dispersed, the shape adjustment channels 13 of the same group are distributed along the circumferential direction of the needle disk retractable member 4, and multiple groups of shape adjustment channels 13 are distributed along the radial direction of the needle disk retractable member 4.

[0029] Among them, the shape adjustment channels 13 are set to three groups. The shape adjustment channels 13 are set as arc-shaped through holes for multiple anti-bird thorns 5 to pass through. The arc-shaped through hole close to the outer edge of the needle disk retractable member 4 is the first group, and the arc-shaped through hole close to the center of the needle disk retractable member 4 is the third group. The second group of arc-shaped through holes is located between the first group and the second group. The number of the shape adjustment channels 13 in the first group is four, and the number of the shape adjustment channels 13 in the second group and the third group is two, and the first group, the second group and the third group are all evenly distributed on the circumference of the needle disk retractable member 4 and are all symmetrically distributed with respect to the radial direction of the needle disk retractable member 4.

[0030] Among them, the shape adjustment channels 13 are set to three groups. The shape adjustment channels 13 are set as circular holes, and the number of circular holes in each group decreases in turn. The first group of shape adjustment channels 13 is close to the outer edge of the needle disk retractable member 4, the second group and the third group are successively close to the center of the needle disk retractable member 4, and at the same time, the shape adjustment channels 13 in each group are evenly distributed along the circumferential direction of the needle disk retractable member 4.

[0031] Among them, the shape adjustment channels 13 are set to three groups, and the shape adjustment channels 13 are set to polygonal holes. The first group of shape adjustment channels 13 is close to the outer edge of the needle punching disc retractor 4, and the second and third groups are successively close to the center of the needle punching disc retractor 4. At the same time, the shape adjustment channels 13 of each group are evenly distributed along the circumferential direction of the needle punching disc retractor 4. Among them, the edges of the polygonal holes on both sides of each limiting hole 12 are set to be arc-shaped.

[0032] The inner diameter of the arc-shaped through hole is larger than that of the circular hole and the polygonal hole, so that the number of anti-bird needles 5 extending in is larger, and at the same time the activity range is wider. Relatively speaking, it does not need to be too precise during processing; the inner diameter of the circular hole is smaller than that of the arc-shaped through hole and the polygonal hole, so that the number of anti-bird needles 5 extending in is lower, and at the same time the activity range is smaller. Relatively speaking, it is more precise during processing.

[0033] In order to ensure that the needle punching disc retractor 4 can be fixed on the anti-bird needles 5 when the anti-bird needles 5 need to be retracted, therefore, limiting members 6 are provided on two of the anti-bird needles 5 located at the edge. Specifically, they can be set as rubber plugs. The rubber plugs are located in the middle or upper middle part of the anti-bird needles 5. Two corresponding limiting holes 12 are opened on the needle punching disc retractor 4. It should be noted that the maximum diameter of the rubber plug is slightly larger than the inner diameter of the limiting hole 12. In this way, the rubber plug can enter the limiting hole 12 so that the needle punching disc retractor 4 is locked on the anti-bird needles 5. The fixing method of the rubber plug and the anti-bird needles 5 is a conventional existing technology in the art, and will not be elaborated here.

[0034] As Figures 5 - 8 shown, in order to facilitate the movement of the needle punching disc retractor 4, a vertical needle punching control rod 17 is detachably provided on the needle punching disc retractor 4. After passing through the center of the needle punching disc retractor 4, the needle punching control rod 17 can be connected to the needle punching disc base. A through hole 15 for the needle punching control rod 17 to pass through is provided at the center of the needle punching disc retractor 4. The needle punching control rod 17 is bent to form a hook ring 9, so that the needle punching disc retractor 4 can be moved by hooking the hook ring 9 with an auxiliary tool.

[0035] One end of the acupuncture control rod 17 close to the acupuncture disc base is provided with an external thread section 11, and the acupuncture control rod 17 can rotate on the acupuncture disc retractor 4. A screw hole adapted to the external thread section 11 is provided on the acupuncture disc base. After the acupuncture control rod 17 passes through the center of the acupuncture disc retractor 4, the external thread section 11 can be screwed with the screw hole to fix the acupuncture control rod 17 to the acupuncture disc base, so as to fix the acupuncture disc retractor 4 to the acupuncture disc base, ensuring that when used on an inclined surface, the cooperation between the acupuncture disc retractor 4 and the acupuncture disc base is closer, and the acupuncture disc retractor 4 will not move on the anti-bird acupuncture 5. The acupuncture control rod 17 can rotate on the acupuncture disc retractor 4. When it is necessary to retract the anti-bird acupuncture 5, the acupuncture control rod 17 can be rotated first to make the external thread section 11 rotate out of the screw hole, and then the acupuncture control rod 17 can be moved.

[0036] As Figures 2 - 6 shown, in order to ensure that the acupuncture control rod 17 can rotate and be detachable on the acupuncture disc retractor 4, therefore, a fixing member 10 is provided on the part of the acupuncture control rod 17 close to the external thread section 11, and the fixing member 10 is used to fix the acupuncture disc retractor 4 on the acupuncture control rod 17. A perforation is provided at the center of the acupuncture disc retractor 4. The fixing member 10 includes two elastic protrusions. The acupuncture control rod 17 passes through the perforation, and when the external thread section 11 is screwed with the internal thread section on the acupuncture disc base, the two elastic protrusions are respectively located on both sides of the acupuncture disc retractor 4, and the elastic protrusions are in contact with the surface of the acupuncture disc retractor 4. A bearing can also be provided in the perforation to realize the rotation of the acupuncture control rod 17 through the bearing.

[0037] As Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 shown, the acupuncture disc base includes a support plate 1, a mounting seat 2 and an acupuncture form box 3. Both the mounting seat 2 and the acupuncture form box 3 are bowl-shaped structures with openings facing downwards. The open end of the mounting seat 2 is fixedly arranged on the support plate 1, and the open end of the acupuncture form box 3 is fixedly arranged on the mounting seat 2. There is a gap between the mounting seat 2 and the acupuncture form box 3. All the anti-bird acupuncture 5 are movably arranged on the support plate 1. A plurality of sliding grooves 14 for all the anti-bird acupuncture 5 to pass through are provided on the closed ends of the mounting seat 2 and the acupuncture form box 3. A fixator 7 is fixedly connected to the lower end surface of the support plate 1. The fixator 7 is fixedly arranged on equipment such as a pole tower through a connector 8. The fixator 7 and the connector 8 are connected by bolts, and the connector 8 and the equipment such as the pole tower are also connected by bolts to fix the anti-bird acupuncture 5 in sequence. The models and specific structures of the fixator 7 and the connector 8 are conventional prior arts in this field and will not be described in detail here. The pole tower is also a conventional prior art in this field and will not be described in detail here.

[0038] As Figure 9 and Figure 10 shown, the slideways 14 on the mounting base 2 and the slideways 14 on the needle-punching form box 3 are multiple concentric circles. The two outermost circles of slideways 14 are strip-shaped and their length directions are the same as the radial direction of the concentric circles. The lengths of the slideways 14 increase in sequence from the inner circle to the outer circle. How to set to ensure that the slideways 14 do not affect the spreading of the anti-bird needles 5 is conventional technology in the art and will not be elaborated here. Since the working environment of the present utility model is outdoors, in order to avoid water accumulation on the needle-punching disc base, therefore, a water leakage hole 16 is provided on the support plate 1.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
