Description

Technical Field

[0001] This utility model relates to the field of soil moisture detection technology, and in particular to a device for detecting soil moisture at different depths beneath the crust of desert soil. Background Technology

[0002] Desert crusts (biological or physical crusts) are an important component of desert ecosystems. Their formation alters the surface soil structure and significantly affects precipitation infiltration, water evaporation, and deep soil moisture replenishment. Accurate detection of soil moisture at different depths beneath the crust is the core foundation for revealing desert hydrological cycles, assessing vegetation restoration potential, and formulating water-saving and sand-fixing strategies.

[0003] The existing technology has the following problems:

[0004] There are two existing methods for accurately detecting soil moisture at different depths below the crust: direct measurement and indirect measurement. Direct measurement is highly destructive, while indirect measurement uses a probe for non-real-time monitoring of time-domain reflectometry, which is costly. Sandy soils are prone to poor contact between the probe and the soil, leading to increased errors, and the probe length is limited. Utility Model Content

[0005] The main purpose of this invention is to provide a device for detecting soil moisture at different depths beneath the crust of desert soil, which can effectively solve the problems of large errors and limited detection depth.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A device for detecting soil moisture at different depths beneath desert crust includes a tripod, a central tube fixedly connected to the inner side of the tripod, three ring-shaped support plates rotatably connected to the lower side of the tripod, a rotating mechanism movably mounted on the central tube, and a drilling mechanism rotatably connected to the inner side of the rotating mechanism.

[0008] The drilling mechanism includes a rotating tube, the inner side of which is rotatably connected to the inner side of the central tube. A drilling rod is sleeved on the inner side of the rotating tube. A conveying mechanism is movably installed on the upper side of the rotating tube. A drill bit is fixedly connected to the lower side of the drilling rod.

[0009] Preferably, the outer side of the drill rod is provided with several annularly distributed limiting grooves.

[0010] Preferably, a plurality of annularly distributed electromagnetic telescopic rods are fixedly connected to the inner side of the side wall of the rotating tube, and rollers are rotatably connected to the sides of the plurality of electromagnetic telescopic rods that are close to each other, and the outer side of the rollers is slidably connected to the inner side of the limiting groove.

[0011] Preferably, a plurality of annularly distributed electric telescopic rods are fixedly connected to the inner side of the drill bit, and a humidity detector is fixedly connected to the lower side of each of the plurality of electric telescopic rods.

[0012] Preferably, a plurality of annularly distributed push blocks are fixedly connected to the lower side of the rotating tube, and the outer side of the push blocks is slidably connected to the inner side of the limiting groove.

[0013] Preferably, an extension rod is attached to the upper side of the drill rod, a screw is fixedly connected to the inner side of the extension rod, and the outer side of the screw is threadedly connected to the inner side of the drill rod.

[0014] Preferably, the inner sides of both the drill rod and the extension rod are rotatably connected to a rotating plate near the upper side.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model provides a soil moisture detection device for different depths under the desert crust. Based on the cooperation of a rotating mechanism, a drilling mechanism, a rotating tube, a conveying mechanism, a drilling rod, a drill bit, an extension rod, and a screw, the rotating mechanism drives the rotating tube to rotate, and then the conveying mechanism drives the drilling rod to convey the drill bit downward to drill into the lower layer of the desert crust. By relying on the spliced ​​extension rod, the purpose of detecting soil moisture at deeper locations can be achieved. Since the extension rod is a standard part, the cost increase caused by customized probes is reduced. At the same time, the humidity detector is directly delivered to the detection position, avoiding the contact problems caused by using probes.

[0017] 2. This utility model provides a soil moisture detection device at different depths under the crust of desert soil. Based on the cooperation of the rotating tube, the drilling rod, the electromagnetic telescopic rod, and the rollers, multiple rollers are set to be inserted into the limiting groove to stabilize the drilling rod, thereby avoiding the problem of wear leading to an increase in the gap between the drilling rod and the rotating tube, which reduces the life of the components.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-5 As shown, a device for detecting soil moisture at different depths under a desert crust includes a tripod 1, a central tube 2 fixedly connected to the inner side of the tripod 1, three ring-shaped support plates 3 rotatably connected to the lower side of the tripod 1, a rotating mechanism 4 movably mounted on the central tube 2, and a drilling mechanism 5 rotatably connected to the inner side of the rotating mechanism 4.

[0026] The drilling mechanism 5 includes a rotating tube 51, the inner side of which is rotatably connected to the inner side of the central tube 2. A drilling rod 53 is sleeved on the inner side of the rotating tube 51. A conveying mechanism 52 is movably installed on the upper side of the rotating tube 51. A drill bit 54 is fixedly connected to the lower side of the drilling rod 53.

[0027] It should be noted that tripod 1 is an existing tripod support structure, which allows for length adjustment of each support leg and is equipped with a level to check the stability of the equipment. This is existing technology and will not be described in detail here. Support plate 3 is rotatably connected to the bottom of the support leg on tripod 1 to increase the contact area with the ground. A wireless charging module is provided between the central tube 2 and the rotating tube 51. The rotating tube 51 is equipped with a battery, so that the central tube 2 supplies power to the battery on the rotating tube 51 via an external cable. The rotating mechanism 4 contains a motor, gears, and a gear ring. The motor drives the gears to rotate, which in turn causes the gear ring to rotate. The gear ring is placed on the outside of the rotating tube 51 to achieve the purpose of rotating the rotating tube 51. The conveying mechanism 52 is equipped with a motor and a conveying wheel. The motor drives the conveying wheel to rotate, which causes the conveying wheel to move the drill rod 53 up and down. The conveying wheel increases the friction between itself and the drill rod 53 by means of rubber, and the distance between the conveying wheels is adjusted by means of an electrically controlled telescopic component.

[0028] like Figure 3 As shown, several annularly distributed limiting grooves 57 are provided on the outer side of the drill rod 53.

[0029] It should be noted that the conveying wheel on the conveying mechanism 52 is engaged in the limiting groove 57, and at the same time the material drilled by the drill bit 54 is conveyed upward from the limiting groove 57.

[0030] like Figure 3 As shown, a number of annularly distributed electromagnetic telescopic rods 55 are fixedly connected to the inner side of the side wall of the rotating tube 51. Rollers 56 are rotatably connected to the sides of the electromagnetic telescopic rods 55 that are close to each other. The outer side of the rollers 56 is slidably connected to the inner side of the limiting groove 57.

[0031] It should be noted that the electromagnetic telescopic rod 55 is used to drive the roller 56 to move, and the roller 56 clamps the rod into the limiting groove 57, thereby stabilizing the drill rod 53 in the rotating tube 51.

[0032] like Figure 3 As shown, several annularly distributed electric telescopic rods 58 are fixedly connected to the inner side of the drill bit 54, and humidity detectors 59 are fixedly connected to the lower side of each of the electric telescopic rods 58.

[0033] It should be noted that the electric telescopic rod 58 drives the humidity detector 59 to move up and down, so that when it reaches the detection position, the humidity detector 59 is directly sent out of the drill bit 54 to realize the detection of soil moisture.

[0034] like Figure 3 As shown, a number of ring-shaped push blocks 510 are fixedly connected to the lower side of the rotating tube 51, and the outer side of the push blocks 510 is slidably connected to the inner side of the limiting groove 57.

[0035] It should be noted that the push block 510 is used to push out the sand in the limiting groove 57 to prevent the sand in the drill rod 53 from affecting the normal operation of the equipment when it is reset. The push block 510 is made of elastic material, such as rubber.

[0036] like Figure 5 As shown, an extension rod 511 is attached to the upper side of the drill rod 53, and a screw 512 is fixedly connected to the inner side of the extension rod 511. The outer side of the screw 512 is threadedly connected to the inner side of the drill rod 53.

[0037] It should be noted that the extension rod 511 is used to extend the length of the screw 512 to enable detection at deeper locations such as 0-5dm, 5-10dm, and 10-20dm. Both the extension rod 511 and the drill rod 53 have scale lines on their outer sides to indicate the depth to which the drill bit 54 enters the sand.

[0038] like Figure 5 As shown, the inner sides of the drill rod 53 and the extension rod 511 are rotatably connected to a rotating plate 513 near the upper side.

[0039] It should be noted that the rotating plate 513 is used to cover the charging interface provided inside the drill rod 53 and the extension rod 511. There is an elastic contact between the drill rod 53 and the extension rod 511 to connect the power transmission wires inside the drill rod 53 and the extension rod 511. When the position to be detected is reached, the uppermost rotating plate 513 is pushed open, and then the interface covered by the rotating plate 513 is inserted to realize external control of the bottom electric telescopic rod 58.

[0040] The working principle of this utility model is as follows: First, the rotating mechanism 4 contains a motor, gears, and a gear ring. The motor drives the gears to rotate, which in turn causes the gear ring to rotate. The gear ring is placed on the outside of the rotating tube 51 to achieve the purpose of rotating the rotating tube 51. The conveying mechanism 52 is equipped with a motor and a conveying wheel. The motor drives the conveying wheel to rotate, causing the conveying wheel to move the drill rod 53 up and down. The conveying wheel increases the friction between itself and the drill rod 53 using rubber. The distance between the conveying wheels is adjusted by an electrically controlled telescopic component. The rotating plate 513 is used to cover the charging interface set inside the drill rod 53 and the extension rod 511. There is an elastic contact between the drill rod 53 and the extension rod 511 to connect the power transmission wires inside the drill rod 53 and the extension rod 511. When the position to be detected is reached, the uppermost rotating plate 513 is pushed open, and then the interface covered by the rotating plate 513 is inserted to realize external power supply to the bottom. The control of the telescopic rod 58 is achieved by rotating the rotating tube 51 through the rotating mechanism 4. Then, the conveying mechanism 52 drives the drill rod 53 downward to drill the drill bit 54 into the lower layer of the desert crust. By relying on the spliced ​​extension rod 511, the purpose of detecting soil moisture at deeper locations can be achieved. Since the extension rod 511 is a standard part, the cost increase caused by customized probes is reduced. At the same time, the humidity detector 59 is directly sent to the detection position, avoiding the contact problems caused by using probes. Finally, the electromagnetic telescopic rod 55 is used to drive the roller 56 to move. The roller 56 is clamped into the limiting groove 57, thereby stabilizing the drill rod 53 in the rotating tube 51. By setting multiple rollers 56 to be clamped into the limiting groove 57, the purpose of stabilizing the drill rod 53 is achieved, thereby avoiding the problem of increased gap between the drill rod 53 and the rotating tube 51 due to wear, which would reduce the life of the components.
