Description

Technical Field

[0001] The utility model relates to the technical field of bird-repelling ammunition, in particular to a timed bird-repelling bullet. Background Art

[0002] Because there are often birds circling in the sky above the airport, birds often get caught in the engines of aircraft or collide with high-speed aircraft, which seriously threatens the flight safety of aircraft. In order to disperse the flocks of birds, bird repellent cannons are usually deployed around the airport. Bird repellent eggs filled with bird repellent are fired into the air through the bird repellent cannons, and the bird repellent is released into the air to disperse the flocks of birds through the explosion sound.

[0003] In order to avoid the pollution of the ground environment caused by the firing of shells, pneumatic bird-repelling cannons with compressed gas as the power are often used as the launching device to launch the bird-repelling shells into the air and explode them in the air. The ignition method of the existing pneumatic bird-repelling cannon bird-repelling shells is that the friction agent in the charge paper pad arranged in the shell body is ignited by the relative friction between the ignition wire arranged in the shell body and the friction agent, and the flame generated by the friction agent ignites the fuse.

[0004] The existing pneumatic bird-repelling cannon uses the friction between the ignition wire and the friction agent to ignite the bird-repelling bullet. During the use of the bird-repelling bullet, it is very easy to ignite the bird-repelling bullet due to improper operation, and the use process is unsafe. Utility Model Content

[0022] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0023] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] like Figure 1 As shown, in one embodiment, the pneumatic bird-repelling cannon bird-repelling bomb 100 includes an explosion module and an ignition module. The explosion module includes a closed cavity formed by a shell 1 and a plugging material 2, and explosives 3 and bird repellents 4 are arranged side by side in the closed cavity. Since the pneumatic bird-repelling cannon bird-repelling bomb 100 in the utility model uses high-pressure gas as power when firing, rather than traditional gunpowder power, the strength requirement for the shell 1 is relatively low, so a paper shell with low cost and more convenient material can be used. In other embodiments, metal, leather or plastic can also be used as the shell 1. In one embodiment of the utility model, plugging mud is used as the plugging material 2 to reduce the production cost of the bird-repelling bomb.

[0026] The pneumatic bird-repelling bullet 100 for bird-repelling cannon of the utility model adopts an electronic ignition method. The bird-repelling bullet includes an ignition module composed of a circuit board 5 and an ignition control circuit installed on the circuit board 5. The ignition control circuit includes a power supply 6, a timer switch control module (not shown) and an ignition head 7, and the ignition head 7 extends into the explosive 3. After the ignition control circuit is turned on, the ignition head 7 ignites the explosive 3.

[0027] For guaranteeing to have better bird-repelling effect, the bird-repelling bomb must keep a suitable distance from the flock of birds. Therefore, it is necessary to control the height of the bird-repelling bomb to be moderate when exploding, so the pneumatic bird-repelling gun adopts a time switch control module with the bird-repelling bomb 100. In one embodiment, the time switch control module is a TTL serial port module. In order to quickly ignite the explosive 3, in other embodiments, the quantity of the ignition head 7 can be one or more. The power supply 6 is a button battery.

[0028] like Figure 2As shown, in order to ignite the explosive 3 more safely, the circuit board 5 has a front side located in a confined space and a back side exposed to the outside, the ignition control circuit is arranged on the front side, and the back side is provided with contacts 9 (such as Figure 3 The signal sensing unit 10 is electrically connected to the input end of the timing switch control module. In one embodiment, a wiring is formed in the circuit board 5 along the thickness direction of the circuit board 5, one end of the wiring is electrically connected to the signal sensing unit 10, and the other end is electrically connected to the timing switch control module. The ignition control circuit is usually in a disconnected state. When the contact 9 of the control module 8 of the bird-repelling gun contacts the signal sensing unit 10, the input end of the timing switch control module receives a trigger signal (such as a current signal) through the signal sensing unit 10, the timing switch control module is started, and the timing switch control module closes and turns on the ignition control circuit.

[0029] like Figure 2 As shown, in order to facilitate the contact point 9 of the control module 8 of the bird-repelling gun to contact with the signal sensing part 10, in one embodiment, the signal sensing part 10 is four concentric rings with different radiuses electrically connected to the time switch control module respectively. Two of the rings are used to be connected with the contact point 9 of the control module 8 of the bird-repelling gun to close the disconnected ignition control circuit, and the other two rings are connected with the contact point 9 of the control module 8 of the bird-repelling gun to control the time when the bird-repelling bullet explodes. In other embodiments, the signal sensing part 10 can also be arranged as four concentric boxes. Other arrangements that can facilitate the contact point 9 of the control module 8 to contact with the signal sensing part 10 all belong to the protection scope of the present utility model and will not be repeated here.

[0030] To prevent the dust of the explosive 3 inside the bird-repelling bomb from falling onto the circuit board 5, causing a short circuit and affecting the operation of the circuit board 5. In one embodiment, the circuit board 5 is covered with an insulating rubber layer for isolating dust, and the insulating rubber layer covers the front of the circuit board 5 and the ignition control circuit, and does not cover the end of the ignition head 7 that penetrates into the explosive 3. In other embodiments, an insulating plastic film may be used instead of the insulating rubber layer.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
