Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model and outstanding effect are described in detail; but these embodiments; only for the utility model is described; not in order to limit protection domain of the present utility model; any it will be understood by those skilled in the art that; do not depart from equivalent variations and the amendment under the prerequisite of design of the present utility model and principle, made, all should belong to the scope of the utility model protection.
A kind of soil moisture sensor flush mounting that the utility model provides is the installation transformation of carrying out by means of earth boring auger.As shown in Figure 1, common earth boring auger generally comprises handle 1, drilling pipe 2 and drill bit 3 three parts, and the utility model utilizes earth boring auger exactly, and one section of annular pipeline section 4 is set.This annular pipeline section 4 can be both to get a section of hollow drilling pipe 2, can be also one section of annular tube-carrier independently making, was connected on drilling pipe 2, and the most feasible mode is connected between the bottom and drill bit 3 of drilling pipe certainly, appearance as shown in Figure 1.Why this section of annular pipeline section 4 is designed to the annular of hollow, be also for casting used.
Core component of the present utility model is all inner setting of this annular pipeline section 4, and needle sensor is embedded in wherein.As shown in Figure 2, in order to protect needle sensor, designed a long conveying trough 5 in the entity portion of annular pipeline section 4, pin type probe 6 arranges wherein, for the forward and backward telescopic moving of probe.In conveying trough end on the outer wall of just right annular pipeline section 4, be provided with probe aperture 7, pin type probe can arrive in soil through this hole.
The mobile driving mechanism that relies on of needle sensor is realized, driving mechanism can have various ways, such as a kind of be stepper motor drive under conveyer mechanism, as shown in Figure 3, comprise a stepper motor 8 and two transmission shafts 9, and a travelling belt 10, sensor is fixed on travelling belt, stepper motor 8 drives transmission shaft 9 and travelling belt 10 to rotate, and sensor moves along with the rotation of travelling belt.The forward and backward band dynamic sensor reach of stepper motor is stretched out annular pipeline section 4 in soil, or retreats and be retracted into annular pipeline section 4, and probe is protected.Or another kind of driving mechanism is, stepper motor drives lower screw structure, comprises stepper motor, leading screw, feed screw nut, and fixation of sensor on nut, is accompanied by the rotation of driven by motor leading screw, feed screw nut rectilinear movement, thus be with dynamic sensor to move forward and backward.Can also be pinion and rack etc. other can do the form moving linearly, do not do too much introduction at this.。
Because pin type probe 6 can move, so without the outside of stretching at drilling pipe always, be retracted in drilling pipe by driving mechanism when need not working.Utilize earth boring auger that this telescopic structure band is buried down, both can utilize the sensor of stylus structure to realize the test to deep soil, also can protect probe.
Further, this needle sensor can be single needle-shaped formula, can be also crosspointer run-in index, or even three pins, four pins.Relate to the problem of range and error, words range and error that number of probes is many are all more satisfactory, and ring pipe is a kind of symmetry structure in addition again, thus can select two probe separates formulas, or two single needle sensors are set up in parallel.Fig. 2 device soil moisture sensor used is the crosspointer structure sensor based on common on market, be customized to the model of two probe separates (being equivalent to two parallel single needle formula probes), because the effect of probe is only equivalent to electrode, so also can serve the same role after probe separates in theory.
Further; in order better to protect probe; can one pressure transducer 11 be set at sensor probe tail end; allow probe contact with pressure transducer; when probe enters after soil, the pressure that pressure transducer Real-Time Monitoring probe is suffered, in the time that pressure is greater than preset value (this preset value be used for preventing still continuing when probe from directly contacting stone mobile and cause damaging); monolithic processor controlled stepper motor 8 stops operating immediately or even reverses, the retraction of popping one's head in.In pressure remains on feasible pressure limit time, probe inserts soil, until measure soil water content, and send data to single-chip microcomputer, and be further back to data terminal.
Further; in order better to protect probe; also in order to prevent soil access to plant; can arrange one and fan movably partition of curved surface 12; between conveying trough and probe aperture, as shown in Figure 2,3, prerequisite is on annular pipeline section 4, to make in advance a curved surface groove 13 in position; partition of curved surface 12 is placed on wherein, and curved surface groove 13 connects between conveying trough and probe aperture and with both.Partition of curved surface 12 is a circular arc plate, with annular pipeline section 4 concentrics.Partition of curved surface 12 is also driven and is moved up and down by a division board driving mechanism.Division board driving mechanism can be the rack and pinion drive mechanism under stepper motor drive, as shown in Figure 4, tooth bar 14 is fixed on partition of curved surface 12, and gear 15 is driven by stepper motor 16, thereby wheel and rack engagement drives partition of curved surface to move up and down along curved surface groove.In the time not needing to survey soil moisture, moisture transducer probe is retracted in device, and motor driven division board falls, and blocks probe aperture; In the time that sensor is surveyed soil moisture, division board is opened, and sensor probe stretches out.
Above-mentioned division board stepper motor, sensor stepper motor, pressure transducer, moisture transducer are all electrically connected with a single-chip microcomputer 17, and single-chip microcomputer is electrically connected with ground terminal, is uploaded and ordered down the middle Link role passing by single-chip microcomputer executing data.Moisture transducer can be sent to single-chip microcomputer by the signal of receiving, then sends data to terminal through single-chip microcomputer by reception of wireless signals/transmitter.
This soil moisture sensor flush mounting; simple in structure; easy to operate; in the above-mentioned embodiment exemplifying, can realize the function of multiple protective, the one, the design of the sensor probe of automatic telescopic; can ensure the demand that deep soil is imbedded; the 2nd, the design of division board, can not enter soil by protective device, and the 3rd, arranging of pressure transducer can be avoided moisture transducer overwork.
