Description

Technical Field

[0001] The invention belongs to the technical field of transformer substation auxiliary equipment, and in particular relates to a detachable bird-proofing device for a transformer substation. Background Art

[0002] In the power system, substations are key facilities, and their normal operation is crucial to the stability of the power grid. However, bird activities often pose a threat to the safety of substations. For example, if birds touch equipment during nesting, roosting or flying, it may cause serious consequences such as short circuits, failures or even fires. Therefore, taking effective bird-proofing measures is of great significance to ensure the safe operation of substations. At present, the common bird-repelling methods are divided into: laser bird-repelling and percussion bird-repelling; laser bird-repelling equipment can quickly emit a strong but safe laser beam, instantly attracting and scaring birds, forcing them to fly away from the target area. This instant response capability helps to quickly reduce bird activities and reduce potential threats to crops, flight safety or equipment operation. Laser bird-repelling technology does not produce pollution, will not harm birds or damage the ecological environment. It is a non-lethal, non-invasive solution that conforms to the concept of modern ecological protection. Several common bird-repelling technologies have the following problems: 1. Limitations of laser bird repellent technology: In recent years, laser bird repellent technology has been applied in many fields due to its advantages of non-contact and remote control. By emitting laser beams to disturb or drive away birds, this method has achieved good results in open areas such as farmland and orchards. However, for substations close to airports, laser bird repellent technology has great limitations. On the one hand, laser beams may interfere with the navigation equipment of aircraft and affect flight safety; on the other hand, there are strict restrictions on light pollution near airports, and laser bird repellent equipment may cause unnecessary disputes and complaints. Therefore, in the field of bird prevention in substations, laser bird repellent technology is not applicable.

[0003] 2. Disadvantages of traditional bird-repelling methods: Traditional bird-repelling methods mainly use knocking devices, such as windmills and knocking sticks, to drive away birds by producing knocking sounds under the action of wind. This method has played a bird-repelling role to a certain extent, but over time, birds may gradually adapt to the frequency and pattern of the knocking, thereby reducing the repelling effect.

[0004] 3. Problems that cannot be driven away in layers: Substations have complex structures, and equipment at different heights has different requirements for bird prevention measures. Traditional bird prevention methods can only be used to drive away equipment at a certain height, and cannot achieve layered driving. This results in some equipment still being threatened by birds, and the bird prevention effect is limited. At the same time, due to the high flexibility and uncertainty of bird activities, a single bird prevention method is difficult to fully cover all potential threat points.

[0005] Therefore, it is necessary to provide a new detachable bird-proofing device for a substation to solve the above technical problems. Summary of the invention

[0032] It should be noted that, in order to prevent interference, the lowest point of the ribbon 8 is higher than the highest point of the blade 5, and several ribbons 8 are of different colors.

[0033] The working principle of the detachable bird-proof device for a substation provided by the present invention is as follows: 1. Initial state The detachable bird-proofing device for the substation is installed on the top of the substation body 1 and is fixedly connected by a connecting seat 2 and a hollow connecting rod 3.

[0034] The fan blades 5 rotate freely in the middle of the hollow connecting rod 3, and the square rod 4 is slidably connected to the top end of the hollow connecting rod 3. Initially, the square rod 4 is in a lower position, and the ribbon 8 is hung on the top end of the square rod 4.

[0035] The refractors 12 are equidistantly mounted outside the hollow connecting rod 3 and are in a stationary state.

[0036] The connecting rod assembly 9 is connected to the square rod 4 through a rotating folding mechanism and is in a folded state.

[0037] The driving mechanism 10, the frequency switching mechanism 11, the shaking mechanism 13 and the rotating and folding mechanism are all in the initial positions.

[0038] 2. The fan blade 5 rotates and the driving mechanism 10 works When wind blows the fan blades 5, the fan blades 5 start to rotate.

[0039] The axis of the fan blade 5 extends into the hollow connecting rod 3 and the driving bevel gear 101 fixedly connected at the axis of the fan blade 5 rotates accordingly.

[0040] The driving bevel gear 101 is meshedly connected with the driven bevel gear 103 , so the driven bevel gear 103 also rotates, driving the connecting shaft 102 to rotate.

[0041] The reciprocating screw rod 104 at the top of the connecting shaft 102 performs reciprocating motion. Since one end of the reciprocating screw rod 104 is installed in cooperation with the inner wall of the square rod 4, the square rod 4 performs up and down reciprocating motion along the axis direction of the reciprocating screw rod 104, driving the ribbon 8 to move up and down.

[0042] 3. Expanding and folding the connecting rod assembly 9 When the square rod 4 rises, the control rod 141 and the square rod 4 are kept relatively fixed in position through the cooperation between the limiting block 143 and the limiting groove 142 .

[0043] The connecting shaft 102 is fixedly connected to the reciprocating screw 104, so the two rotate synchronously, and the reciprocating screw 104 is rotationally connected to the control rod 141, and the limiting groove 142 on the control rod 141 is limited by the limiting block 143. Therefore, when the connecting shaft 102 and the reciprocating screw 104 rotate synchronously, the square rod 4 rises and limits the control rod 141 from rotating with the connecting shaft 102.

[0044] The control block 148 slides along the guide groove 144 through the lever 146 . When the control block 148 moves into the spiral groove 145 , the lever 146 rotates along the spiral groove 145 , driving the connecting rod assembly 9 to rotate.

[0045] The two upper folding rods 91 and the two lower folding rods 92 of the connecting rod assembly 9 are folded relative to each other, so that the lateral area of ​​the connecting rod assembly 9 is increased. If a colored light is installed on the connecting rod assembly 9, the colored light shakes with the shaking of the connecting rod assembly, thereby achieving a bird-repelling effect.

[0046] 4. Operation of the frequency switching mechanism 11 The driven gear 107 rotates along with the connecting shaft 102 , and the extension rod 111 and the driving pulley 112 at the axis thereof also rotate synchronously.

[0047] The driving pulley 112 is connected to the driven pulley 115 through a belt transmission, so that the rotating rod 113 and the inclined wheel 114 rotate.

[0048] The top rod 116 in the middle of the bracket 106 is pushed up and down during the rotation of the inclined wheel 114, and the added iron block, rubber block, and plastic block at the top of the top rod 116 contact the shell 6 to generate sound waves of different frequencies.

[0049] Since the materials and weights of the top rod 116 are different, the response speed and strength to the inclined wheel 114 are also different, thereby generating different frequency changes, which interfere with the hearing system of the birds.

[0050] 5. Working of the shaking mechanism The rotation of the rotating rod 113 also drives the inclined rod 131 to rotate.

[0051] The inclined rod 131 makes the shaking platform 134 and the refractor 12 shake continuously through the cooperation between the shaking platform 134 and the square-shaped connecting frame 133 .

[0052] The shaking of the refractor 12 refracts sunlight, again achieving the bird-repelling effect.

[0053] 6. Overall effect of the installation The rotation of the fan blades 5 drives multiple mechanisms to work together, including the up and down movement of the square rod 4, the unfolding and folding of the connecting rod assembly 9, the change of the sound wave frequency of the frequency switching mechanism 11, and the shaking of the refractor 12 of the shaking mechanism 13.

[0054] These actions together create visual, auditory and light interference, effectively repelling birds and preventing them from approaching the substation and posing a safety hazard.

[0055] The above content is a further detailed description of the present invention in combination with a specific preferred embodiment. It cannot be determined that the specific embodiments of the present invention are limited to this.
