Technical Field
The utility model relates to a gardens survey and drawing technical field especially relates to a sensor for measuring trunk growth changes.
Background
The traditional measurement of the diameter growth amount of the trees has the following defects: 1. the time resolution of the tree measuring instrument is low, and the reason why the rapid change of the diameter of the tree is ignored until now is that the time resolution and the sensitivity of the tree measuring instrument are lacked. The time interval of the traditional method for measuring the diameter growth amount of the trees is generally 1 year, 5 years and 10 years, more than 1 year is taken as the main time, the time span is large, and the change of the trees with high growth speed in a short time is difficult to observe;
2. the manual measurement has high cost, and the regular reexamination is difficult to be realized in places which are inconvenient to traffic and difficult to measure; climbing or felling not only wastes time, labor and danger, but also influences the growth of trees and hinders unbiased measurement;
3. the measurement result can not be automatically recorded, and most of the measurement results need to be manually recorded and stored;
4. the data acquisition equipment is old and has low efficiency;
at present, the rapid-response automatic tree measuring instrument is used for measuring, and the laser tree measuring instrument is used for measuring, so that the instruments are too expensive and cannot be popularized and used. Therefore, a fast-response tree measuring instrument is needed to measure the growth of trees to analyze the influence of drought, chemical fertilizer, moisture and other environmental factors on the growth of trees.

the utility model provides a sensor for measuring trunk growth changes, includes shell, displacement sensor subassembly, dead lever, fixed block and hand screw, the dead lever is fixed on the trunk, the fixed block is fixed on the shell, the displacement sensor subassembly is fixed on the fixed block, hand screw fixes on the fixed block, and passes through hand screw fixes the fixed block on the dead lever, dead lever one end is provided with the fixed rod head, displacement sensor subassembly port department is provided with displacement probe.
Preferably, the head of the fixing rod is self-tapping threads, the diameter of the thread bottom is larger than that of the rear L-shaped rod, and the fixing rod can be rotationally fixed on the trunk without pre-drilling a bottom hole.
Preferably, the fixing rod is fixed by screwing it onto the trunk of the tree by means of a sleeve.
Preferably, the head of the fixing rod is screwed to the center of the trunk, and the fixing block is fixed on the fixing rod through the hand-screwed screw, so that the displacement probe tightly pushes the trunk and has a certain compression amount.
Preferably, displacement sensor subassembly top is provided with rain-proof lid, prevents that the rainwater from getting into the sensor.
Compared with the prior art, the utility model discloses possess following advantage:
this scheme is with the help of the sleeve with the dead lever rotation fixation to the trunk on measurement area, trunk central point puts until the dead lever head is twisted, fix the sensor on the dead lever through hand screw, and adjusting position contacts the trunk until displacement probe, come reflection trunk growth variation condition through displacement probe stroke change, with data transmission to terminal through the host computer, realize automatic acquisition and store trunk growth minute variable data, and can combine PC APP end to carry out data viewing, the thing networking intelligent hardware monitoring system solution of analysis, be applicable to the scientific research, teaching, agriculture, horticulture, biological science and technology and more extensive field.
