The invention further provides a land space planning topography measuring device based on the unmanned plane platform, which is described with reference to the accompanying drawings and the specific embodiments.
Referring to fig. 1 to 7, an example of a land space planning terrain measurement apparatus based on an unmanned aerial vehicle platform includes: the unmanned aerial vehicle comprises an unmanned aerial vehicle platform 1, a connecting jack 2, a release mechanism 3, a camera 4 and a descent control mechanism 5; specifically:
referring to fig. 1 and 2, the connection socket 2 is fixed on the belly of the unmanned aerial vehicle platform 1, and the bottom surface of the connection socket 2 is provided with a socket, and the top wall of the socket is provided with an electromagnet 201, which is connected with the power supply system of the unmanned aerial vehicle platform 1 through a controller, so as to control the on-off of the power supply of the electromagnet 201. The electromagnet 201 works to generate magnetic force after being electrified so as to connect the connection socket 2 and the release mechanism 3 into a whole. When unmanned aerial vehicle platform 1 detects that its flight status is out of control, to the power supply of signal shutoff electro-magnet 201 is sent to the controller, lose then to release mechanism 3's adsorption, release mechanism 3 and camera 4 and slow-down mechanism 5 descend under the dead weight effect and break away from with unmanned aerial vehicle platform 1, prevent that camera 4 falls down the back along with unmanned aerial vehicle platform 1 out of control and takes place to damage because of strong striking.
Referring to fig. 3 and 4, the release mechanism 3 includes: insert 301, magnetic attraction piece 302, feeler lever 303, spring 304 and linear bearing 305. Wherein: the insert 301 is a horizontally arranged strip structure, and the lower surface of the insert is fixedly connected to the top surface of the camera 4. The magnetic attraction piece 302 is a strip-shaped structure, and is inlaid and fixed in a groove on the upper surface of the insert 301. Since the plug 301 needs to be inserted into the socket of the connection socket 2 to achieve connection between the two, the socket on the bottom surface of the connection socket 2 has an elongated structure that matches the shape of the upper end of the plug 301. The magnetic attraction piece 302 can be made of iron or steel materials, so that the magnetic attraction piece and the connection socket 2 are fixedly connected together through magnetic force generated by the electromagnet 201. The feeler lever 303 is vertically arranged at the rear end of the camera 4, and the upper end of the feeler lever 303 movably passes through the plug 301 and then abuts against the top wall of the socket.
The spring 304 is sleeved on the feeler lever 303, the linear bearing 305 is vertically arranged on the rear end face of the camera 4, and the side wall of the linear bearing 305 is fixedly connected with the rear end face of the camera 4. The lower end of the contact rod 303 slides through the linear bearing 305 and extends below it.

A limiting piece 306 is fixed on the side wall of the feeler lever 303, and the upper end of the spring 304 is limited at the limiting piece 306. By limiting the upper and lower ends of the spring 304, the feeler lever 303 is pressed down to compress the spring 304 after the plug 301 enters the socket of the connection socket 2, thereby realizing the energy storage of the spring 304. When the plug 301 and the connection socket 2 are separated, the spring 304 loses constraint and drives the feeler lever 303 to reset under the action of the elastic potential energy accumulated by the spring, so that the ejection mechanism 503 starts to release the parachute 502. Meanwhile, in this embodiment, the lower end of the feeler lever 303 is supported by the linear bearing 305 in a sliding manner, so that the feeler lever 303 operates more smoothly and is more stable, and the imaging device is mounted on the unmanned aerial vehicle platform 1 by means of the cooperation among the linear bearing 305, the limiting piece 306, the feeler lever 303 and the connection socket 2, so as to lay a foundation for starting the descent control mechanism 5.
Referring to fig. 5, the descent control device 5 includes: a housing cavity 501, a parachute 502 and an ejector mechanism 503. Wherein: the accommodating cavity 501 is a tube body with an open front end, and may be a square tube, a round tube, etc. The receiving cavity 501 is horizontally fixed on the bottom surface of the camera 4 and is opposite to the insert 301 on the upper surface of the camera 4, i.e. the insert 301 and the receiving cavity 501 are symmetrically distributed on the upper and lower surfaces of the camera 4. The parachute 502 is positioned in the front port of the receiving chamber 501, and the parachute 502 is connected to the ejection mechanism 503. Specifically, the ejection mechanism 503 includes: a push plate 5031, a push rod 5032, an elastic cord 5033, and a pulling cord 5034. Wherein: the push plate 5031 is located in the lumen of the housing cavity 501 and behind the parachute 502, and the shape of the push plate 5031 matches the cross-sectional shape of the lumen of the housing cavity 501. The pushing plate 5031 is connected with the parachute 502 in front of the pushing plate by ropes. The push rod 5032 is located in the lumen of the receiving cavity 501 and behind the push plate 5031. The front end of the push rod 5032 is vertically and fixedly connected with the back surface of the push plate 5031. Both ends of the elastic rope 5033 are fixedly connected to the inner wall of the accommodating cavity 501, and the rear end of the push rod 5032 is connected to the middle part of the elastic rope 5033, so that energy is stored by using the elastic rope 5033. Meanwhile, the present embodiment stores the push plate 5031, the push rod 5032 and the parachute 502 in the accommodating chamber 501 so that the parachute 502 is pushed out and released from the front end port of the accommodating chamber 501 by the driving force provided by the elastic cord 5033 after triggering. One end of the pulling rope 5034 is connected with the rear end of the push rod 5032, the other end of the pulling rope 5034 passes through a through hole on the rear end face of the accommodating cavity 501 and is sleeved on the side wall of the lower end of the trolley 303, at this time, the elastic rope 5033 is in a stretching energy storage state, and the elastic rope 5033 is positioned behind the push plate 5031. In a specific embodiment, referring to fig. 3, 5 and 7, the other end of the pulling rope 5034 is connected to a collar 5035, and the collar 5035 is sleeved on the lower end sidewall of the feeler lever 303. It should be appreciated that the size of the through hole in the rear face of the housing 501 is sufficient for the pull cord 5034 and collar 5035 to pass freely.
Referring to fig. 6, when the insert 301 is not mounted in the connection socket 2, the upper end of the feeler 303 passes through the upper surface of the insert 301 and extends above it under the action of the spring 304. When the plug 301 is inserted into the connection socket 2 and then fixedly connected together by the electromagnet 201, the upper end of the feeler lever 303 is pressed to be lowered to be flush with the upper surface of the plug 301, so that the lower end of the feeler lever 303 is lowered to the rear end of the accommodating cavity 501. Then, the end of the pulling rope 5034 is sleeved on the lower end side wall of the trolley 303, and the image pickup device is carried on the unmanned aerial vehicle platform 1. When the system of the unmanned aerial vehicle platform 1 detects that the flight of the unmanned aerial vehicle platform is out of control, the power supply to the electromagnet 201 is cut off, and at the moment, the plug 301 is separated from the connection socket 2 under the action of the gravity of the release mechanism 3, the camera 4 and the descent control mechanism 5. Meanwhile, after the upper end of the feeler lever 303 loses constraint, the feeler lever 303 moves up as a whole under the drive of the spring 304, so that the lower end of the feeler lever 303 is separated from the elastic cord 5033. At this time, the elastic rope 5033 in the state of tensile energy storage is reset instantaneously, and the push plate 5031 and the push rod 5032 are ejected, so that the parachute 502 is pushed out and released from the front end port of the accommodating cavity 501 (refer to fig. 7), and the speed of the falling of the camera 4 can be effectively reduced after the parachute 502 is opened, so that the camera can slowly fall onto the ground, and damage to the onboard camera caused by impact can be reduced.

The elastic cord 5033 passes through the perforation 5036, so that the lower end of the push rod 5032 is movably connected with the elastic cord 5033. The flexible connection manner facilitates the automatic adjustment of the contact position between the push rod 5032 and the elastic rope 5033 during the landing process of the parachute 502, so that the pulling force of the push rod 5032 to the elastic rope 5033 is in a more balanced and dispersed state, and the elastic rope 5033 on one side of the push rod 5032 is prevented from being broken due to overlarge stress.
In another embodiment, referring to fig. 5, in the land space planning topography measuring device based on the unmanned plane platform as exemplified in the above embodiment, a sealing plug 504 is connected to the front port of the accommodating cavity 501, so as to help prevent the parachute 502 from being randomly released from the accommodating cavity 501 due to the influence of air flow during the flight of the unmanned plane platform 1.
