Technical Field

[0001] This invention belongs to the field of monitoring equipment technology, and specifically relates to a monitoring device for wild birds. Background Technology

[0002] With social development, the protection of wild animals has been continuously strengthened, and the protection of wetland birds has also been continuously improved and perfected. In the process of wetland bird protection, it is often necessary to obtain information on bird species, population size, and living habits. The acquisition of such bird information often requires the use of monitoring equipment to monitor birds in wetlands.

[0003] The main shortcomings of the monitoring equipment on the market are as follows: (1) The monitoring equipment is usually used on land and cannot meet the requirement of being able to be installed in water, wetlands and land at the same time; (2) The monitoring equipment does not have an automatic calibration function and is prone to tilting, overturning and other phenomena, which cannot guarantee that the monitor always has the maximum shooting angle to monitor and shoot the environment in the wild, thus affecting the monitoring effect. Summary of the Invention

[0004] To address the above shortcomings, the technical problem to be solved by the present invention is to provide a monitoring device for wild birds. This monitoring device can be installed in different environments and has an automatic adjustment function to ensure that it always has the maximum shooting angle.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0006] A monitoring device for wild birds includes a monitoring device and a monitoring adjustment device. The monitoring adjustment device is connected to the monitoring device and adjusts the vertical state of the monitoring device. A monitoring fixing device is retractably installed inside the monitoring device and is used to support the monitoring device.

[0007] The monitoring device includes a monitor, a monitoring pole, and an image transmission device. The monitor and the image transmission device are respectively installed on the monitoring pole. The monitoring adjustment device is sleeved on the outside of the monitoring pole to adjust the vertical state of the monitoring pole. The monitoring fixing device is telescopically installed on the monitoring pole.

[0008] As a preferred embodiment of the present invention, a monitoring room and a telescopic room are formed inside the monitoring frame pole. The monitor is detachably installed on the monitoring room, the image transmission device is installed in the monitoring room, and the monitoring fixing device is installed in the telescopic room.

[0009] As a preferred embodiment of the present invention, the monitoring fixing device includes a fixed support leg and a support leg mechanism.

[0010] As a preferred embodiment of the present invention, a telescopic cavity is formed in the side wall of the monitoring frame pole, and the fixed support leg is telescopically installed in the telescopic cavity. An opening groove is also formed on the side wall of the monitoring frame pole, and the opening groove is connected to the telescopic cavity. The fixed support leg is supported by the opening groove.

[0011] As a preferred embodiment of the present invention, a sliding groove is formed on the side wall of the telescopic cavity, and the fixed support foot is slidably installed in the sliding groove through a rotating shaft. The sliding groove extends into the opening groove. When the fixed support foot slides into the opening groove, the support foot mechanism opens the fixed support foot.

[0012] As a preferred embodiment of the present invention, the support mechanism includes a drive motor, a lead screw, a slider, and a connecting rod. The drive motor is fixedly installed in the telescopic chamber, the lead screw is connected to the drive motor, the slider is slidably installed on the outside of the lead screw, and the two ends of the connecting rod are rotatably connected to the slider and the fixed support foot, respectively.

[0013] As a preferred embodiment of the present invention, a connecting rod groove is formed on the side wall of the telescopic chamber, and the connecting rod passes through the connecting rod groove and is connected to the fixed support foot and the slider respectively. A motor groove is formed at the lower end of the telescopic chamber, and the drive motor is installed in the motor groove to increase the gravity at the lower end of the monitoring frame.

[0014] As a preferred embodiment of the present invention, the fixed support leg includes a first support leg, a second support leg, and a support leg spring. The first support leg has a telescopic hole formed inside, and the second support leg is connected to a telescopic rod. The telescopic rod is slidably installed in the telescopic hole. The support leg spring is connected to the first support leg and the second support leg respectively, so as to open the first support leg and the second support leg.

[0015] As a preferred embodiment of the present invention, the lower end of the second leg is tapered, and similarly, the lower end of the monitoring pole is tapered, which reduces the contact area between the monitoring equipment and the ground and improves the stability of the overhead device fixed on the ground.

[0016] As a preferred embodiment of the present invention, the monitor includes a monitoring housing and a panoramic camera. The panoramic camera is installed inside the monitoring housing, and a mounting cylinder is connected to the lower end of the monitoring housing.

The float is mounted on the monitoring frame pole, the buoyancy adjustment component is installed inside the float to adjust the buoyancy of the float, and the inclination sensor is mounted on the monitoring housing.

[0018] As a preferred embodiment of the present invention, the float plate is formed with partition cavities, and each partition cavity is equipped with a buoyancy adjustment component to adjust the buoyancy of each partition cavity.

[0019] As a preferred embodiment of the present invention, the buoyancy adjustment assembly includes an electric cylinder and a piston plate. The piston plate is slidably installed in the partition cavity. The electric cylinder is connected to the piston plate and drives the piston plate to slide up and down.

[0020] As a preferred embodiment of the present invention, an electric cylinder housing is installed at the lower end of the float plate, the electric cylinder housing covers the outside of the electric cylinder, and sound-absorbing material is filled between the electric cylinder housing and the electric cylinder.

[0021] The beneficial effects of the present invention are: (1) the monitoring device is adjusted to a vertical state by the monitoring and adjustment device, thereby ensuring that the monitoring device is always in a shooting state with the maximum shooting angle, so as to facilitate the recording of the species, population and living habits of birds in the surrounding environment, and the transmission of image and video data through the image transmission device in the monitoring device 1.

[0022] (2) A retractable monitoring fixing device is installed inside the monitoring device. Under normal circumstances, the monitoring fixing device is in a retracted state. When it is necessary to place or fix the monitoring equipment on the bottom surface, the monitoring fixing device extends out from the monitoring device, thereby supporting the monitoring device on the land or wetland surface through the monitoring fixing device.

Detailed Implementation

[0030] The present invention will now be further described with reference to the accompanying drawings.

[0031] A monitoring device for wild birds includes a monitoring device 1 and a monitoring adjustment device 2. The monitoring adjustment device 2 is connected to the monitoring device 1 and adjusts the monitoring device 1 to a vertical position, thereby ensuring that the monitoring device 1 is always in a shooting state with the maximum shooting angle. This facilitates the recording of bird species, population numbers, and living habits in the surrounding environment, and transmits image and video data through the image transmission components 1-3 within the monitoring device 1. A retractable monitoring fixing device 3 is installed within the monitoring device 1. Normally, the monitoring fixing device 3 is in a retracted state. When it is necessary to place or fix the monitoring device on the ground, the monitoring fixing device 3 extends from the monitoring device 1, thereby supporting the monitoring device 1 on the land or wetland surface.

[0032] The monitoring and adjustment device 2 in this embodiment includes a float 2-1, a buoyancy adjustment component 2-2, and a tilt sensor 2-3. The float 2-1 has a large buoyancy, which makes it easy to place the monitoring device on the water surface. The buoyancy adjustment component 2-2 is used to adjust the buoyancy of the float 2-1 at various points, thereby ensuring that the monitoring pole 1-2 is in a vertical state. Due to the action of wind force and the self-weight generated by birds perching, the float 2-1 may tilt or overturn. During the tilting process, the tilt sensor 2-3 is used to detect the tilt of the monitoring pole 1-2. When the tilt of the monitoring pole 1-2 is detected, the buoyancy adjustment component 2-2 is controlled to work, so that the monitoring pole 1-2 returns to a vertical state.

[0033] To facilitate the control of the verticality of the monitoring frame pole 1-2 by the float plate 2-1, the float plate 2-1 is installed on the monitoring frame pole 1-2, the buoyancy adjustment component 2-2 is installed inside the float plate 2-1 to adjust the buoyancy of the float plate 2-1, and the tilt sensor 2-3 is installed on the inner wall of the monitoring frame pole 1-2.

[0034] The float 2-1 has a partitioned cavity 2-4 formed inside. Each partitioned cavity 2-4 is equipped with a buoyancy adjustment component 2-2. The buoyancy of each partitioned cavity 2-4 is adjusted by changing the water-to-air ratio in the partitioned cavity through the buoyancy adjustment component 2-2. By adjusting different partitioned cavities 2-4 separately, different buoyancy is generated in different parts of the float 2-1, thereby neutralizing the tilting force caused by factors such as wind force and the weight of birds, thus ensuring that the monitoring pole 1-2 is in a vertical state.

[0035] The buoyancy adjustment component 2-2 includes an electric cylinder 2-5 and a piston plate 2-6. The piston plate 2-6 is slidably installed in the partition cavity 2-4. The electric cylinder 2-5 is connected to the piston plate 2-6 and drives the piston plate 2-6 to slide up and down. The area above the piston plate 2-6 is air, and the area below the piston plate 2-6 is water. By moving the piston plate 2-6, the air content in the partition cavity 2-4 is changed, thereby changing the buoyancy of the partition cavity 2-4 at that location, thus neutralizing the tilting force on the monitoring frame 1-2.

[0036] To facilitate the vertical movement of the piston plate 2-6, a drain hole 2-7 and an air inlet hole 2-8 are formed on the side wall of the partition cavity 2-4. The air inlet hole 2-8 is located at the top of the partition cavity 2-4, and the exhaust hole 2-7 is located on the side wall of the partition cavity 2-4.

[0037] The lower end of the float plate 2-1 is equipped with an electric cylinder housing 2-9, which covers the outside of the electric cylinder 2-5. The space between the electric cylinder housing 2-9 and the electric cylinder 2-5 is filled with sound-absorbing material. The electric cylinder housing 2-9 and the sound-absorbing material reduce the noise generated when the electric cylinder is working, prevent the noise from affecting the surrounding birds, and facilitate better monitoring of the surrounding birds.

[0038] The monitoring device 1 includes a monitor 1-1, a monitoring pole 1-2, and an image transmission component 1-3. The monitor 1-1 and the image transmission component 1-3 are respectively installed on the monitoring pole 1-2. The monitor 1-1 is used to collect information about birds in the surrounding environment and send it to the image transmission component 1-3. The image transmission component 1-3 then sends the image information to a designated cloud platform via a network or Bluetooth. The monitoring adjustment device 2 is sleeved on the outside of the monitoring pole 1-2. The vertical state of the monitoring pole 1-2 is adjusted by the monitoring adjustment device 2. The monitoring fixing device 3 is telescopically installed on the monitoring pole 1-2, which facilitates the storage of the monitoring fixing device 3.

[0039] In some preferred embodiments, the image transmission unit 1-3 includes a storage unit, a data analyzer, and a communicator. The storage unit is used to store bird information acquired by the monitor 1-1, the data analyzer is used to analyze information such as the species and population size of surrounding birds, and the communicator is used to transmit the aforementioned information such as the species and population size of birds.

[0040] The monitoring frame 1-2 has a monitoring room 1-4 and a telescopic chamber 1-5 formed inside. The monitor 1-1 is detachably installed on the monitoring room 1-4. The image transmission device 1-3 is installed inside the monitoring room 1-4. The monitoring fixing device 3 is installed inside the telescopic chamber 1-5. The monitoring room 1-4 and the telescopic chamber 1-5 are set up separately to ensure that the monitoring room 1-4 is in a dry and sealed state, thus ensuring the service life of the monitoring equipment.

[0041] The monitor 1-1 includes a monitoring housing 1-6 and a panoramic camera 1-7. The panoramic camera 1-7 is installed inside the monitoring housing 1-6, which protects the panoramic camera 1-7 and ensures its service life. The lower end of the monitoring housing 1-6 is connected to a mounting cylinder 1-8, which is connected to the monitoring frame pole 1-2.

[0042] In some preferred embodiments, an installation step 1-9 is formed on the outer wall of the monitoring pole 1-2, the lower end face of the monitoring adjustment device 2 is fixed on the installation step 1-9, and the upper end face of the monitoring adjustment device 2 abuts against the lower part of the installation cylinder 1-8, thereby fixing the monitoring adjustment device 2 and the monitoring pole 1-2 through the installation cylinder 1-8.

[0043] In some preferred embodiments, a rubber ring is installed on the upper surface of the mounting steps 1-9 to prevent relative rotation between the monitoring adjustment device 2 and the monitoring frame 1-2.

[0044] In some preferred embodiments, an L-shaped slot 1-10 is formed on the side wall of the monitoring pole 1-2, and a corresponding clip is formed on the inner wall of the mounting cylinder 1-8. The clip is inserted into the L-shaped slot 1-10. When the clip is inserted into the horizontal part of the L-shaped slot 1-10, the mounting cylinder 1-8 is rotated to fix the mounting cylinder 1-8 and the monitoring pole 1-2. This eliminates the need for excessive rotation of the mounting cylinder 1-8 and prevents the panoramic camera 1-7 from malfunctioning during the installation of the mounting cylinder 1-8.

[0045] When this monitoring device is installed on land or when the buoyancy of the monitoring adjustment device 2 fails (the monitoring pole 1-2 is partially submerged in water and the float 2-1 is completely on the water surface), the contact area between the monitoring pole 1-2 and the ground is increased by the monitoring fixing device 3, which makes it easier to deploy this monitoring device on land.

[0046] The monitoring fixed device 3 includes a fixed support leg 3-1 and a support mechanism 3-2. The fixed support leg 3-1 is telescopically installed on the outside of the monitoring pole 1-2. The support mechanism 3-2 is connected to the fixed support leg 3-1 and drives the fixed support leg 3-1 to move and spread. The fixed support leg 3-1 increases the contact area between the monitoring pole 1-2 and the ground, making it easier to deploy the monitoring device on land.

[0047] A telescopic cavity 3-3 is formed inside the side wall of the monitoring pole 1-2. The fixed support leg 3-1 is telescopically installed inside the telescopic cavity 3-3. An opening groove 3-4 is also formed on the side wall of the monitoring pole 1-2. The opening groove 3-4 is connected to the telescopic cavity 3-3. The fixed support leg 3-1 is spread open through the opening groove 3-4. The support mechanism 3-2 drives the fixed support leg 3-1 to move along the telescopic cavity 3-3. When the pivot of the fixed support leg 3-1 moves to the opening groove 3-4, the fixed support leg 3-1 can no longer move downward. As the support mechanism 3-2 moves downward, the fixed support leg 3-1 is spread open, thereby increasing the contact area between the monitoring pole 1-2 and the ground.

[0048] A sliding groove 3-5 is formed on the side wall of the telescopic cavity 3-3. The fixed support leg 3-1 is slidably installed in the sliding groove 3-5 through a rotating shaft. The sliding groove 3-5 extends into the opening groove 3-4. During the downward movement of the fixed support leg 3-1, since the telescopic cavity 3-3 has only one opening direction, the fixed support leg 3-1 moves along the direction extending out of the telescopic cavity 3-3. When the fixed support leg 3-1 moves to the lowest point (moves into the opening groove 3-4), the fixed support leg 3-1 cannot move down. It is supported by the foot support mechanism 3-2, which opens the fixed support leg 3-1.

[0049] The support mechanism 3-2 includes a drive motor 3-6, a lead screw 3-7, a slider 3-8, and a connecting rod 3-9. The drive motor 3-6 is fixedly installed inside the telescopic chamber 1-5. The lead screw 3-7 is connected to the drive motor 3-6. The slider 3-8 is slidably installed on the outside of the lead screw 3-7. The motor drives the slider 3-8 to move up and down. The two ends of the connecting rod 3-9 are rotatably connected to the slider 3-8 and the fixed support 3-1, respectively. During the downward movement of the slider 3-8, the connecting rod 3-9 drives the fixed support to move down. When the fixed support 3-1 moves to the lowest point, the slider 3-8 continues to move down, driving one end of the connecting rod 3-9 to move down, causing the angle between the connecting rod 3-9 and the fixed support 3-1 to change, thereby causing the fixed support 3-1 to open.

[0050] To facilitate the connection of the two ends of the connecting rod 3-9 to the slider 3-8 and the fixed support 3-1 respectively, a connecting rod groove 3-10 is formed on the side wall of the telescopic chamber 1-5. The connecting rod 3-9 passes through the connecting rod groove 3-10 and is connected to the fixed support 3-1 and the slider 3-8 respectively.

[0051] The lower end of the telescopic chamber 1-5 is formed with a motor groove 3-11. The drive motor 3-6 is installed in the motor groove 3-11. The drive motor 3-6 is installed at the lower end of the monitoring pole 1-2, which increases the gravity at the lower end of the monitoring pole 1-2, so that the monitoring equipment has better stability when floating on the water surface.

[0052] The fixed support leg 3-1 includes a first support leg 3-1-1, a second support leg 3-1-2, and a support spring 3-1-3. The first support leg 3-1-1 has a telescopic hole 3-1-5 formed inside. The second support leg 3-1-2 is connected to a telescopic rod 3-1-4, which is slidably installed in the telescopic hole 3-1-5. The support spring 3-1-3 is connected to the first support leg 3-1-1 and the second support leg 3-1-2 respectively, which spreads the first support leg 3-1-1 and the second support leg 3-1-2 apart. The support spring 3-1-3 provides a certain rebound force to neutralize part of the tilting force on the monitoring frame 1-2.

[0053] This embodiment uses a telescopic fixed support leg 3-1. Compared with a non-telescopic fixed support leg 3-1, this telescopic fixed support leg 3-1 has a better cushioning effect. Furthermore, the telescopic fixed support leg 3-1 makes it easier for the fixed support 3-1 to deform according to the terrain of the bottom surface, thus improving the convenience of the fixed support leg 3-1 opening process.

[0054] The lower end of the second support leg 3-1-2 is tapered. Similarly, the lower end of the monitoring pole 1-2 is tapered, which reduces the contact area between the monitoring equipment and the ground and improves the stability of the overhead device fixed on the ground.

[0055] The installation environment and installation method for this monitoring equipment are as follows.

[0056] (1) When this monitoring device is installed on land, directly insert the monitoring pole 1-2 of the monitoring device into the bottom surface, and ensure that the monitoring pole 1-2 is in a vertical state during installation.

[0057] (2) When the monitoring device is deployed in a deeper water area; the piston plate 2-6 is located in the middle of the partition cavity 2-4. When the monitoring rod 1-2 tilts, the piston plate 2-6 is driven, which causes the buoyancy of the float plate to change, thereby causing the float plate to generate a certain tilting buoyancy, thus overcoming the tilting force of the monitoring rod 1-2 and ensuring that the monitoring rod 1-2 is in a vertical state.

[0058] In case (3), when the monitoring device is deployed in shallow water, the pressure sensor at the bottom of the monitoring pole 1-2 determines whether the monitoring pole 1-2 is in contact with the riverbed. If there is no contact, the monitoring device remains vertical in the same way as in case (2).

[0059] When the water level drops, the pressure sensor at the bottom of the monitoring pole 1-2 detects that the monitoring pole 1-2 is in contact with the riverbed. At this time, the piston plate 2-6 moves up and stores liquid in the partition chamber 2-4, causing the monitoring device to sink as a whole. At the same time, the fixed support leg 3-1 is opened. When the water level continues to drop, the monitoring pole 1-2 tilts and the liquid in the partition chamber 2-4 is discharged through the piston plate 2-6, causing the extension of the fixed support leg 3-1 on one side to change. The support leg spring 3-1-3 generates different supporting forces, thereby causing the monitoring pole 1-2 to return to the vertical state. When the water level rises, the monitoring device remains vertical in the same way as in the above situation (2).

[0060] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention; therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0061] Although this document makes extensive use of terms corresponding to the figure labels, the possibility of using other terms is not excluded; these terms are used merely to more conveniently describe and explain the essence of the invention; interpreting them as any kind of additional limitation would be contrary to the spirit of the invention.
