Technical Field

[0001] The present invention belongs to the technical field of protective devices, and specifically relates to a protective device for a wireless bridge. Background Art

[0002] A wireless bridge is the bridge of a wireless network. It uses wireless transmission to build a communication bridge between two or more networks, and can seamlessly connect local area networks dozens of kilometers apart to create a unified enterprise or metropolitan area network system. When a wireless bridge is in use, it is generally installed at a relatively high position, which makes it easy for birds to stay on it. The excrement of birds is likely to accumulate on the wireless bridge and cause corrosion to it. Therefore, a protective device for a wireless bridge is needed to solve the above problems. Summary of the Invention

[0003] In view of the above situation, to overcome the defects of the prior art, the present invention provides a protective device for a wireless bridge, which effectively solves the problem that when the wireless bridge is at a relatively high position in the air, it is easy for birds to stay on the wireless bridge, resulting in the excrement produced by the birds being easily accumulated on the housing of the wireless bridge, and being prone to corrode the housing of the wireless bridge after long-term accumulation.

[0004] To achieve the above object, the present invention provides the following technical solution: A protective device for a wireless bridge includes a baffle plate inclined and fixedly arranged on the main body of the wireless bridge and a bird repelling mechanism fixedly arranged on the baffle plate; the bird repelling mechanism includes a rod body fixedly arranged at the top end of the baffle plate, a rotating cylinder arranged on the rod body and rotatably connected to the rod body, and a plurality of bird repelling components arranged evenly along the circumferential direction of the rotating cylinder. The top end of the rod body forms a spike portion; among them, the bird repelling component includes a horizontal spring, a connecting rod, and a bird repeller. The horizontal spring is fixedly arranged on the outer wall of the rotating cylinder, the connecting rod is fixedly arranged at the end of the horizontal spring, and the bird repeller is fixedly arranged at the end of the connecting rod.

[0005] The bird repeller includes a cylinder fixedly arranged at the end of the connecting rod, a vertical spring fixedly arranged on the inner wall of the cylinder, an outer sphere fixedly arranged at the free end of the vertical spring, a vibrator fixedly arranged at the mouth of the cylinder, and a sound amplifying cylinder located outside the vibrator and fixedly arranged at the mouth of the cylinder; among them, the vibrator includes an elastic ring fixedly arranged at the mouth of the cylinder and a vibrating piece located inside the elastic ring and fixed to the elastic ring.

[0006] Preferably, the shape of the cylinder is cylindrical, the shape of the elastic ring is annular, the shape of the vibrating piece is circular, and the shape of the sound amplifying cylinder is conical.

[0007] Preferably, the interior of the outer sphere is a hollow structure, an arc-shaped opening is formed on the outer wall of the outer sphere, and an inner sphere is movably arranged inside the outer sphere.

[0008] Preferably, a sliding cavity is formed inside the connecting rod. The sliding cavity is inclined, with the end away from the horizontal spring in the sliding cavity being higher than the end close to the horizontal spring. Through holes are formed at both ends of the sliding cavity, and both ends of the sliding cavity communicate with the outside through the two through holes. One of the through holes is located inside the cylinder body and faces the outer sphere. An impact member is slidably arranged inside the sliding cavity.

[0009] Preferably, the impact member includes an impact block and an impact rod. The impact block is slidably arranged inside the sliding cavity, and the impact rod is fixedly arranged on the impact block. When the end of the connecting rod away from the horizontal spring moves downward, the impact rod on the impact block impacts the outer sphere after passing through the through hole located inside the cylinder body under the action of gravity along the sliding cavity.

[0010] Preferably, the bird repelling mechanism further includes a magnetic block. The magnetic blocks are symmetrically and fixedly arranged at the top of the shielding plate and are located on the center line of the shielding plate. The cylinder body is made of a magnetic material, and a reflective sticker is fixedly adhered to the surface of the shielding plate.

[0011] Preferably, a clamping mechanism is further fixedly arranged on the wireless bridge main body. The clamping mechanism includes a fixing frame. An installation groove is formed inside the fixing frame. Installation blocks are symmetrically and slidably arranged inside the installation groove, and the two installation blocks are respectively fixedly arranged with two arc-shaped clamping plates. The clamping mechanism further includes a driving member for driving the displacement of the two arc-shaped clamping plates and a reverse stop member for the one-way displacement of the moving member.

[0012] Preferably, the driving member includes a handle, two racks, two gears, and a bidirectional screw. The two racks are respectively slidably arranged in the corresponding limiting grooves on the fixing frame and the wireless bridge main body. The two racks are respectively fixedly arranged at both ends of the handle. The two gears are respectively meshed with the two racks.

The thread directions at both ends of the bidirectional screw are opposite, and the two ends of the bidirectional screw are respectively in threaded cooperation with the screw holes on the two installation blocks.

[0013] Preferably, the reverse stop member includes a horizontal rod, a stop rod, and a stop spring. The horizontal rod is fixedly arranged on the outer wall of the wireless bridge main body. The stop rod is hinged to the horizontal rod, and the stop rod is fixedly arranged on the outer wall of the wireless bridge main body through the stop spring.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1) During operation, through the arranged bird repelling components, when there is wind in the air, it will cause the bird repeller, the connecting rod, and the horizontal spring to rotate around the rod body through the rotating cylinder, so as to strike the staying birds through the rotated bird repeller, preventing the birds from staying at the top line of the shielding plate;

[0016] 2) During work, through the installed bird repeller, when the wind causes the cylinder to shake, under the action of the vertical spring, the outer sphere continuously impacts the vibration plates on both sides of it. After being impacted, the vibration plates produce sounds, and the sounds of the vibration plates are amplified through the megaphone, thereby scaring the birds and making them stay away from the device, further improving the bird repelling effect. When the shaking caused by the wind is small, the inner sphere continuously impacts inside the outer sphere, thereby playing a role in repelling birds through the sounds generated by the two;

[0017] 3) Through the installed impact member, when a bird stays on the bird repeller, the connecting rod, and the horizontal spring, it will cause the sliding cavity inside the connecting rod to tilt, causing the impact member to move along the sliding cavity and impact the outer sphere, thereby generating sounds due to the impact between the two. At the same time, it will also cause the outer sphere to impact the inner sphere, generating sounds again to drive away the staying birds;

[0018] 4) Through the installed reflective stickers and magnetic blocks, under the condition of light, the light can be reflected through the reflective stickers to prevent birds from approaching above the wireless bridge main body; through the installed magnetic blocks, a magnetic suction force can be generated on the cylinder, so that when the cylinder is stationary, the axis of the connecting rod connected to the cylinder is above the top line of the baffle, preventing birds from staying on the top line of the baffle;

[0019] 5) Through the installed clamping mechanism, before installation, place the two arc-shaped clamping plates on the outside of the electric pole, and then push the driving member. The driving member drives the two arc-shaped clamping plates to approach each other and clamp and fix the electric pole. No tools are required, and a single person can complete the installation process, which is relatively convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] It is provided by Figure 1-8 ;

[0033] Refer to Figure 1-3, The present invention relates to a protection device for a wireless bridge. In order to solve the problems proposed in the background technology, when the wireless bridge is at a relatively high position in the air, birds are likely to stay on the wireless bridge, and the excrement produced by the birds is likely to accumulate on the housing of the wireless bridge. After long-term accumulation, it is easy to corrode the housing of the wireless bridge, thereby reducing the service life of the wireless bridge. It includes a baffle 2 fixedly arranged obliquely on the wireless bridge main body 1 and a bird repelling mechanism 3 fixedly arranged on the baffle 2; the bird repelling mechanism 3 includes a rod body 301 fixedly arranged at the top end of the baffle 2, a rotating cylinder 302 arranged on the rod body 301 and rotatably connected to the rod body 301, and a plurality of bird repelling components 303 evenly arranged along the circumferential direction of the rotating cylinder 302. The top end of the rod body 301 forms a spike portion; wherein the bird repelling component 303 includes a horizontal spring 4, a connecting rod 5, and a bird repeller 6. The horizontal spring 4 is fixedly arranged on the outer wall of the rotating cylinder 302, the connecting rod 5 is fixedly arranged at the end of the horizontal spring 4, and the bird repeller 6 is fixedly arranged at the end of the connecting rod 5;

[0034] With such a design, since the baffle 2 is obliquely arranged, birds can only stay at the top line of the baffle 2. When there is wind in the air, it will cause the bird repeller 6, the connecting rod 5, and the horizontal spring 4 to rotate around the rod body 301 through the rotating cylinder 302, so as to knock the staying birds through the rotated bird repeller 6 and prevent the birds from staying at the top line of the baffle 2.

[0035] Refer to Figure 4 , In order to further improve the bird repelling effect, the bird repeller 6 includes a cylinder body 601 fixedly arranged at the end of the connecting rod 5, a vertical spring 602 fixedly arranged on the inner wall of the cylinder body 601, an outer sphere 603 fixedly arranged at the free end of the vertical spring 602, a vibrator fixedly arranged at the mouth of the cylinder body 601, and a sound amplifying cylinder 606 located outside the vibrator and fixedly arranged at the mouth of the cylinder body 601; wherein the vibrator includes an elastic ring 604 fixedly arranged at the mouth of the cylinder body 601 and a vibrating piece 605 located inside the elastic ring 604 and fixed to the elastic ring 604;

[0036] With such a design, since the wind in nature is uncertain, when the cylinder body 601 shakes, under the action of the vertical spring 602, the outer sphere 603 continuously impacts the vibrating pieces 605 on both sides of it. After being impacted, the vibrating pieces 605 produce sound, and the sound of the vibrating pieces 605 is amplified through the sound amplifying cylinder 606, thereby scaring the birds and making them stay away from the device, further improving the bird repelling effect.

[0037] Specifically, the shape of the cylinder body 601 is cylindrical, the shape of the elastic ring 604 is annular, the shape of the vibrating piece 605 is circular, and the shape of the sound amplifying cylinder 606 is conical.

[0038] Refer toFigure 5 , considering that when the wind force is small, the shaking of the outer sphere 603 cannot make it contact the vibrating piece 605, so that the vibrating piece 605 cannot play the role of bird repelling. To solve this problem, the inside of the outer sphere 603 is a hollow structure, an arc-shaped opening 6031 is provided on the outer wall of the outer sphere 603, and an inner sphere 6032 is movably arranged inside the outer sphere 603;

[0039] With this design, when the shaking caused by the wind force is small, the inner sphere 6032 continuously impacts inside the outer sphere 603, so as to play the role of bird repelling through the sound generated by the two.

[0040] Refer to Figure 6 , considering that when there is no wind, birds will stay on the bird repeller 6, the connecting rod 5 and the horizontal spring 4. Therefore, to solve this problem, a sliding cavity 501 is provided inside the connecting rod 5, the sliding cavity 501 is inclined, the end of the sliding cavity 501 far from the horizontal spring 4 is higher than the end of the sliding cavity 501 close to the horizontal spring 4, through holes 502 are provided at both ends of the sliding cavity 501, and both ends of the sliding cavity 501 are communicated with the outside through the two through holes 502. One of the through holes 502 is located inside the cylinder 601 and faces the outer sphere 603, and an impact member 7 is slidably arranged inside the sliding cavity 501;

[0041] With this design, when birds stay on the bird repeller 6, the connecting rod 5 and the horizontal spring 4, it will cause the sliding cavity 501 inside the connecting rod 5 to tilt, so that the impact member 7 moves along the sliding cavity 501 and impacts the outer sphere 603, so that the two generate sound due to the impact. At the same time, it will also cause the outer sphere 603 to impact the inner sphere 6032, generating sound again to drive away the staying birds; after the birds leave, under the action of the horizontal spring 4, the bird repeller 6, the connecting rod 5 and the horizontal spring 4 all return to the original horizontal state.

[0042] Specifically, the impact member 7 includes an impact block 701 and an impact rod 702. The impact block 701 is slidably arranged inside the sliding cavity 501, and the impact rod 702 is fixedly arranged on the impact block 701. When the end of the connecting rod 5 far from the horizontal spring 4 moves downward, the impact rod 702 on the impact block 701 impacts the outer sphere 603 along the sliding cavity 501 through the through hole 502 located inside the cylinder 601 under the action of gravity;

[0043] With this design, in the horizontal state, under the action of its own gravity, the impact block 701 is located at the end close to the horizontal spring 4, and when the end of the connecting rod 5 far from the horizontal spring 4 tilts downward, it will cause the impact block 701 to slide under the action of its own gravity, so that the impact block 701 can be recycled.

[0044] Reference Figure 2 , considering that when the connecting rod 5 does not coincide with the top line of the baffle 2, there are still some small-sized birds that can stay on the top line of the baffle 2. To solve this problem, the bird repelling mechanism 3 further includes a magnetic block 304. The magnetic block 304 is symmetrically and fixedly arranged at the top end of the baffle 2 and is located on the center line of the baffle 2. The cylinder body 601 is made of a magnetic adsorption material, and a reflective sticker 201 is fixedly adhered to the surface of the baffle 2;

[0045] With this design, under the condition of light, the reflective sticker 201 can reflect light, and the reflected light will be refracted above the baffle 2, causing discomfort to the eyes of the birds, thereby preventing the birds from approaching above the wireless bridge main body 1; by providing the magnetic block 304, a magnetic suction force can be generated on the cylinder body 601, so that when the cylinder body 601 is stationary, the axis of the connecting rod 5 connected to the cylinder body 601 is located above the top line of the baffle 2, preventing birds from staying on the top line of the baffle 2.

[0046] Reference Figure 7-8 , to facilitate the installation of the wireless bridge main body 1, a clamping mechanism 8 is also fixedly arranged on the wireless bridge main body 1. The clamping mechanism 8 includes a fixing frame 801. An installation groove 802 is opened in the fixing frame 801. Installation blocks 803 are symmetrically and slidably arranged in the installation groove 802. The two installation blocks 803 are respectively fixedly arranged with two arc-shaped clamping plates 804; the clamping mechanism 8 further includes a driving member for driving the displacement of the two arc-shaped clamping plates 804 and a check member for the one-way displacement of the moving member;

[0047] With this design, in the initial state, the two arc-shaped clamping plates 804 are separated from each other, and the distance between the two arc-shaped clamping plates 804 is greater than the diameter of the electric pole to be installed. When the staff reaches the required position, the two arc-shaped clamping plates 804 can be placed outside the electric pole, and then the driving member is pushed. The driving member drives the two arc-shaped clamping plates 804 to approach each other and clamp and fix the electric pole, thus completing the installation process, which is relatively convenient.

[0048] Specifically, the driving member includes a handle 805, two racks 806, two gears 807 and a bidirectional screw 808. Among them, the two racks 806 are respectively slidably arranged in the corresponding limit grooves on the fixing frame 801 and the wireless bridge main body 1. The two racks 806 are respectively fixedly arranged at both ends of the handle 805. The two gears 807 are respectively meshed with the two racks 806. The two gears 807 are respectively fixedly arranged at both ends of the bidirectional screw 808. The bidirectional screw 808 is rotatably arranged inside the installation groove 802. The thread directions at both ends of the bidirectional screw 808 are opposite. The two ends of the bidirectional screw 808 are respectively in threaded cooperation with the screw holes on the two installation blocks 803;

[0049] With such a design, the handle 805 drives the two racks 806 to move. The two racks 806 respectively drive the bidirectional screw rod 808 to rotate through the two gears 807. The bidirectional screw rod 808 drives the two mounting blocks 803 to move by means of threads. The two mounting blocks 803 respectively drive the two arc-shaped clamping plates 804 to move, so as to realize the clamping and fixing of the electric pole through the two arc-shaped clamping plates 804.

[0050] Specifically, the check member includes a horizontal rod 809, a stop rod 810 and a stop spring 811. The horizontal rod 809 is fixedly arranged on the outer wall of the wireless bridge main body 1. The stop rod 810 is hinged to the horizontal rod 809, and the stop rod 810 is fixedly arranged on the outer wall of the wireless bridge main body 1 through the stop spring 811.

[0051] With such a design, under the action of the stop spring 811, the end of the stop rod 810 can stop the rack 806 to prevent the rack 806 from moving in the reverse direction, playing a protective role. When the rack 806 needs to move in the reverse direction, the stop rod 810 can be pressed to make the stop spring 811 contract, so as to release the limit on the rack 806 and facilitate disassembly.
