Those skilled in the art can understand the advantages and effects of the present invention from the contents disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. In addition, the drawings of the present invention are only simple schematic illustrations and are not depicted according to actual dimensions. It is stated in advance. The following embodiments will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention.

[0046] Embodiment 1: This embodiment provides a tower-type low-altitude defense device, combined with Figures 1 to 4 shown.

[0047] A tower-type low-altitude defense device, which includes a tower, a defense module, and a protection plate;

[0048] The defense module is installed on the tower and protrudes from the top of the tower. The defense module is used to identify low-altitude aircraft and send out interference signals;

[0049] The protection plate is rotatably connected to the top of the tower, the rotation axis of the protection plate is arranged in the horizontal direction, and the protection plate is provided with an avoidance hole for the defense module to pass through;

[0050] The tower is equipped with at least four pushing mechanisms, which are respectively located in the front, rear, left and right directions and are adapted to the protection plate. The protection plate is provided with a plurality of rotating grooves, and all the rotating grooves correspond one by one to all the pushing mechanisms. The pushing mechanism includes a pushing member and a pushing block. The pushing member is installed on the tower and drives the connected pushing block. The pushing block slides in the horizontal direction and one end of the pushing block is inserted in the rotating groove. One end of the pushing block is in an arc-shaped structure. A driving mechanism is installed in the tower, and the driving mechanism drives the connected protective plate and causes the protective plate to flip upward from the horizontal direction at any angle.

[0051] Specifically, the structure of the tower is barrel-shaped, an opening is provided on the top of the tower, and the surrounding is sealed.

[0052] In order to achieve the effect of convenient installation design, four pushing mechanisms are provided, and the four pushing mechanisms are respectively located in the front, rear, left and right directions, and the two pushing mechanisms in the front and rear directions are opposite to each other, and the two pushing mechanisms in the left and right directions are opposite to each other; the pushing member can use a cylinder, and the output end of the pushing member moves in the horizontal direction; one end of the pushing block is adapted to the corresponding rotating groove, and one end of the pushing block has an arc-shaped structure to facilitate the rotation of the protective plate, and one end of the pushing block can be spherical or cylindrical; the tower is provided with guide holes corresponding to the pushing blocks one by one, and the pushing blocks are inserted into the guide holes so that the pushing blocks slide into the corresponding rotating groove along a certain direction.

[0053] Correspondingly, there are four rotating grooves, which are respectively arranged opposite to the four pushing mechanisms, and the rotating grooves penetrate the top surface of the protection plate.

[0054] When the driving mechanism is not working, the pushing member is retracted into its output shaft, thereby driving the pushing block to move in the direction close to the corresponding pushing member, thereby causing one end of the pushing block to extend out of the rotating groove. At this time, the protective plate is set horizontally and the defense module works normally; when the defense module identifies the low-altitude aircraft, the driving mechanism determines the flipping direction of the protective plate before working, that is, to ensure that one end of the pushing block in the same direction extends into the corresponding rotating groove, and one end of the pushing blocks in other different directions all extend out of the corresponding rotating groove. Since there are four pushing mechanisms arranged in this embodiment, it is limited that one end of one of the pushing blocks extends into the corresponding rotating groove, and the other three pushing blocks all extend out of the corresponding rotating grooves. At this time, the driving mechanism works to lift the protective plate, and the protective plate is subjected to upward pressure. Due to the reaction force, one end of the pushing block has a downward pressure on the protective plate. At this time, the protective plate will rotate around a certain axis to any angle. When the protective plate flips, due to the pre-set avoidance hole, the defense module will not hinder the flipping of the protective plate. The flipped protective plate can block low-altitude aircraft in a certain direction, thereby starting a certain protection effect on the defense module.

[0055] Optionally, the protection plate includes a main board and at least four rotation shafts;

[0056] The main board is connected to all rotating shafts, and the avoidance hole is located on the main board;

[0057] At least four rotating shafts correspond to at least four pushing mechanisms respectively, the rotating grooves are located on the rotating shafts, and the number of rotating grooves corresponding to one rotating shaft is at least one. A flip groove for the rotating shaft to rotate is arranged on the top of the tower.

[0058] Specifically, in the present embodiment, there are four rotating shafts, which are cylindrical in shape and connected to the main board through a connecting rod. There is a spacing between the rotating shaft and the main board, and the main board will not affect the rotation of the rotating shaft in the corresponding flip groove; the rotating groove runs through the top surface of the rotating shaft; four connecting blocks are fixed on the top of the tower, and the positions of the connecting blocks correspond one by one to the pushing mechanisms respectively. There are four flip grooves, and the four flip grooves are respectively located on the top of the four connecting blocks.

[0059] Optionally, the driving mechanism includes a driving member, a main driving rod and a secondary driving rod;

[0060] The bottom end of the driving member is rotatably connected to the tower, the driving end of the driving member is drivingly connected to one end of the main driving rod, and one end of the main driving rod is rotatably connected to the driving end of the driving member;

[0061] One end of the auxiliary driving rod is rotatably connected to one end of the main driving rod, and the other end of the auxiliary driving rod is rotatably connected to the main board.

[0062] Specifically, the driving member may be a cylinder; the rotation axis of the driving member, the rotation axis of the main driving rod, and the rotation axis of the auxiliary driving rod are all parallel to each other.

[0063] Optionally, an interception mechanism is provided on the surface of the mainboard;

[0064] The interception mechanism is provided with an interception part, and the interception part is used to intercept objects passing through the avoidance hole.

[0065] Optionally, the intercepting part is rotatably arranged, the rotation direction of the intercepting part is parallel to the penetration direction of the avoidance hole, the plane formed by the rotation of the intercepting part is arranged opposite to the avoidance hole, and the area of ​​the plane formed by the rotation of the intercepting part is larger than the area of ​​the avoidance hole.

[0066] Optionally, the interception mechanism includes a rotating interception member, a transmission member and an interception stick;

[0067] The interception member is mounted on the mainboard;

[0068] The transmission member is mounted on the main board, and the interception member drives and connects the transmission member;

[0069] The intercepting stick is in transmission connection with the transmission member, and the intercepting portion is located on the intercepting stick.

[0070] Specifically, the rotating intercepting member may be a motor; the transmission member may be a belt transmission member or a gear transmission member; and the length of the intercepting rod is smaller than the maximum value of the diagonal of the mainboard.

[0071] This embodiment solves the problem that traditional low-altitude defense devices cannot protect the defense module. When a low-altitude aircraft appears, any one of the pushing members pushes the pushing block to insert into the corresponding rotating groove, and the remaining pushing members push the pushing block away from the corresponding rotating groove. At this time, the driving mechanism drives the protective plate to flip the protective plate upward from a horizontal state, and the protective plate forms a certain physical protection for the defense module.

[0072] Embodiment 2: This embodiment includes all the contents of embodiment 1, and provides a tower-type low-altitude defense device, combined with Figure 5 shown.

[0073] The interception mechanism of the tower-type low-altitude defense device is different from the interception mechanism in the first embodiment, and the interception part can cover the avoidance hole.

[0074] Optionally, the interception mechanism includes a movable interception member and an interception plate;

[0075] The movable intercepting member is installed on the main board, and the movable intercepting member drives the connected intercepting plate to slide, and makes the intercepting plate slide to a position facing the avoidance hole, and the intercepting part is located on the intercepting plate.

[0076] Specifically, the movable intercepting member may be a cylinder.

[0077] Embodiment 3: This embodiment includes all the contents of embodiment 1, and provides a tower-type low-altitude defense device, combined with Figure 6 shown.

[0078] A tower-based low-altitude defense device, which also includes a data analysis module and a control module;

[0079] The defense module includes an image acquisition submodule, a preprocessing submodule, a feature extraction submodule, a target detection submodule, an estimation submodule, a recognition submodule, an interference submodule and a data transmission submodule;

[0080] The image acquisition submodule is used to acquire the initial image and transmit the initial image to the preprocessing submodule;

[0081] The preprocessing submodule performs denoising on the initial image;

[0082] The feature extraction submodule extracts the features of the object from the initial image after denoising;

[0083] The identification submodule identifies the low-altitude aircraft according to the extracted features, and transmits the identification information of the low-altitude aircraft to the data transmission submodule;

[0084] The target detection submodule uses the target detection algorithm to track and observe the low-altitude aircraft in real time, obtains the motion trajectory of the low-altitude aircraft and transmits it to the estimation submodule;

[0085] The estimation submodule estimates the flight speed of the low-altitude aircraft and the relative distance between the low-altitude aircraft and the defense module through the position change of the low-altitude aircraft in the image, and determines the flight direction of the low-altitude aircraft according to the flight speed and motion trajectory of the low-altitude aircraft;

[0086] The data transmission submodule transmits the identification information of the low-altitude aircraft and the relative distance between the low-altitude aircraft and the defense module to the data analysis module, and transmits the flight direction of the low-altitude aircraft to the control module;

[0087] The jamming submodule transmits a jamming signal toward the low-altitude aircraft according to the flight direction of the low-altitude aircraft;

[0088] The data analysis module is used to set the safety distance and compare the safety distance, the relative distance between the low-altitude aircraft and the defense module. When the safety distance is less than or equal to the relative distance between the low-altitude aircraft and the defense module, an alarm signal is sent to the control module. When the safety distance is greater than the relative distance between the low-altitude aircraft and the defense module, a normal signal is sent to the control module.

[0089] The control module starts and stops the driving mechanism according to the alarm signal and normal signal, controls the movement of the propulsion mechanism in the corresponding direction according to the flight direction of the low-altitude aircraft, and starts and stops the interception mechanism according to the alarm signal and normal signal.

[0090] Specifically, during actual operation, the defense module can obtain an alarm signal or a normal signal. The alarm signal indicates that the low-altitude aircraft poses a threat to the defense module, and the normal signal indicates that the low-altitude aircraft does not pose a threat to the defense module. The threat here refers to the damage caused by the low-altitude aircraft to the surface of the defense module. When the control module receives the alarm signal, the control module needs to immediately start the driving mechanism to lift the main board. At this time, the control module also controls the movement of the corresponding pushing member according to the flight direction of the low-altitude aircraft. For example, if it is recognized that the flight direction of the low-altitude aircraft moves from the front direction, the corresponding front pushing member pushes the pushing block into the rotating groove, and the pushing members in the other directions push the pushing block out of the rotating groove. At this time, the lifted main board flips to a certain angle to protect the defense module. At the same time, in order to prevent the low-altitude aircraft from passing through the avoidance hole, the control module will also start the rotating interception member or the mobile interception member to block the avoidance hole; the units of the safety distance and the relative distance between the low-altitude aircraft and the defense module are all meter-based.

[0091] The contents disclosed above are only preferred feasible embodiments of the present invention, and do not limit the protection scope of the present invention. Therefore, all equivalent technical changes made using the contents of the present invention description and drawings are included in the protection scope of the present invention. In addition, the elements therein can be updated as technology develops.
