Description

Technical Field

[0001] This utility model relates to the field of soil moisture monitoring technology, and in particular to a soil moisture monitoring device. Background Technology

[0002] A soil moisture monitor is a device used to monitor soil moisture content and is widely used in farmland, orchards, and forests.

[0003] Soil moisture monitoring instruments typically include threaded solar panels and a pole. The pole houses a photovoltaic system, a data processing module, a communication module, a storage module, sensors, and a main control chip that controls the operation and management of these modules. The data processing module communicates with the sensors to process soil moisture, temperature, and other data collected by the sensors. The data processing module, storage module, and communication module communicate with each other to store the processed data locally in the storage module and then upload it to a cloud platform via the communication module. Staff can then access data reports and other information using relevant software.

[0004] The aforementioned photovoltaic system is used to provide power to the sensors and various modules, including a DC combiner box, a solar controller, a battery, and an inverter connected in sequence, thereby converting light energy into electrical energy to improve the battery's endurance.

Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Please see Figure 1 The soil moisture monitoring device of this utility model includes a solar panel 1, a connecting column 23, a rotary plug and a pole 3 connected in sequence from top to bottom.

[0028] In some embodiments, the solar panel 1 can be fixed to the upper end of the connecting column 23 at a certain angle, so that the solar panel 1 faces the sun to receive light energy.

[0029] In other embodiments, such as Figures 2 to 5 The solar panel 1 and the connecting post 23 can be rotatably connected. Specifically, a rotating post 21 is provided between the solar panel 1 and the connecting post 23. The upper end of the rotating post 21 is fixedly connected to the bottom of the solar panel 1. The lower end of the connecting post 23 is provided with external threads, which can be connected to the internal threads of the upright post 3. Furthermore, a sealing ring 24 (such as...) can also be fitted onto the lower end of the connecting post 23. Figure 9 (as shown), thereby improving the sealing between the connecting column 23 and the upright 3.

[0030] The lower end of the rotating column 21 is inserted into the upper end of the connecting column 23. A horizontally positioned pivot shaft 231 passes through the rotating column 21 and the connecting column 23, allowing the rotating column 21 to drive the solar panel 1 to rotate around the axis of the pivot shaft 231. Furthermore, the rotating column 21 is provided with multiple positioning holes 221. A positioning pin 232 is inserted into the connecting column 23, and this positioning pin 232 can be inserted into the positioning hole 221 to lock the rotating column 21.

[0031] As an example, the aforementioned pivot 231 can be a shoulder screw, which is inserted from one side of the connecting post 23, passes through the rotating post 21, and is threaded to the other side of the connecting post 23.

[0032] The aforementioned locating pin 232 can be a screw, which passes through the connecting post 23 and is threaded into the locating hole 221.

[0033] During the adjustment of solar panel 1, first pull out the positioning pin 232. Next, rotate solar panel 1 according to the solar altitude so that it faces the sun. Finally, insert the positioning pin 232 into the corresponding positioning hole 221 to lock solar panel 1. In this way, even if the solar altitude changes due to changes in season or location, adjusting solar panel 1 can ensure the absorption of light energy and improve the endurance of the monitoring equipment.

[0034] In other words, this utility model provides two technical solutions: a fixed connection between the solar panel 1 and the connecting post 23, and a rotatable connection. The rotary plug can be applied to either of these two technical solutions.

[0035] The following explanation uses the example of a rotatable connection between solar panel 1 and connecting post 23 to illustrate the rotary plug. Figures 6 to 12 As shown, the aforementioned rotary plug includes a male connector assembly 4 and a female connector assembly 5 that are inserted into each other. The male connector assembly 4 is rotatable relative to the female connector assembly 5. The male connector assembly 4 is connected to the connecting post 23, and the female connector assembly 5 is connected to the upright post 3.

[0036] like Figures 6 to 9 As shown, the male connector assembly 4 includes a male connector post 41, and a male connector base 42 is fixedly mounted in the middle of the male connector post 41. As an example, the male connector post 41 and the male connector base 42 can be made of plastic and manufactured as a single piece by injection molding.

[0037] Two male head limiting blocks 47 can be provided on the upper end face of the aforementioned male head base 42. An internal thread is formed at the bottom of the connecting post 23, and two male head limiting grooves are provided above the internal thread. In the assembled state, the two male head limiting blocks 47 are installed into the two male head limiting grooves, which can prevent the male head post 41 from rotating and ensure that the male head post 41 and the connecting post 23 are coaxially aligned. It should be noted that the number of the aforementioned male head limiting blocks 47 and male head limiting grooves can also be more than two, and those skilled in the art can adjust them according to actual conditions.

[0038] Furthermore, the male connector assembly 4 also includes a male connector locking ring 48, which is connected to the internal thread of the connecting post 23 and thus tightly engages with the bottom of the male connector base 42, thereby preventing the male connector post 41 from sliding up and down, thus completing the installation of the male connector assembly 4.

[0039] The male connector assembly 4 also includes a male positive electrode 43, a male negative electrode 45, a male positive ring 44, and a male negative ring 46. The male positive ring 44 and male negative ring 46 are spaced apart along the height direction and fitted onto the lower end of the male connector post 41. One end of the male positive electrode 43 and male negative electrode 45 extends from the upper end of the male connector post 41 into the male connector post 41 and is connected to the aforementioned male positive ring 44 and male negative ring 46 respectively. The other end of the male positive electrode 43 and male negative electrode 45 protrudes from the male connector post 41 for connection to the wiring harness of the solar panel 1. The wiring harness of the solar panel 1 can pass through the connecting post 23 and connect to the male positive electrode 43 and male negative electrode 45. The wiring harness of the solar panel 1 can be provided with slack to avoid pulling the wiring harness when adjusting the angle of the solar panel 1.

[0040] like Figures 9 to 12 As shown, the female head assembly 5 includes a hollow female head post 51, and a female head base 52 is fixedly mounted at the bottom of the female head post 51. As an example, the female head post 51 and the female head base 52 can be made of plastic and integrally manufactured by injection molding.

[0041] Two female head limiting blocks 57 can be provided on the lower end face of the female head base 52, and two female head limiting grooves are provided below the internal thread of the upright 3. In the assembled state, the two female head limiting blocks 57 are installed into the two female head limiting grooves, which can prevent the female head column 51 from rotating and ensure that the female head column 51 is coaxial with the upright 3. It should be noted that the number of the above-mentioned female head limiting blocks 57 and female head limiting grooves can also be more than two, and those skilled in the art can adjust them according to the actual situation.

[0042] Furthermore, the female head assembly 5 also includes a female head locking ring 58, which is connected to the internal thread of the upright 3, thereby tightly engaging with the female head base 52 to prevent the female head column 51 from sliding up and down. This completes the installation of the female head assembly 5.

[0043] The female connector assembly 5 also includes a female connector positive electrode 53, a female connector negative electrode 55, a female connector positive ring 54, and a female connector negative ring 56. The female connector positive ring 54 and the female connector negative ring 56 are spaced apart along the height direction on the inner wall of the female connector post 51. One end of the female connector positive electrode 53 and the female connector negative electrode 55 extends into the female connector post 51, correspondingly connecting to the aforementioned female connector positive ring 54 and female connector negative ring 56. The other end of the female connector positive electrode 53 and the female connector negative electrode 55 protrudes from the female connector post 51, and two wire-passing holes are provided on the female connector base 52 for the wire harness to pass through the female connector base and electrically connect to the DC combiner box inside the upright 3.

[0044] The sections of the male positive electrode 43, male negative electrode 45, female positive electrode 53, and female negative electrode 55, except for the wiring positions, can be wrapped with plastic to prevent short circuits.

[0045] During assembly, taking the rotatable connection between solar panel 1 and connecting post 23 as an example, firstly, insert the rotating post 21 into the connecting post 23, install the pivot shaft 231 and the positioning pin 232, and then thread the wiring harness of solar panel 1 into the connecting post 23. Next, connect the wiring harness of solar panel 1 to the male positive electrode 43 and the male negative electrode 45. Then, snap the male limiting block 47 into the male limiting groove and tighten the male locking ring 48 to complete the installation of the male assembly 4.

[0046] Next, pass the DC combiner box wiring harness through the wire hole 521 and connect it to the positive terminal 53 and negative terminal 55 of the female connector. Then, insert the female connector limiting block 57 into the female connector limiting groove and tighten the female connector locking ring 58 to complete the installation of the female connector assembly 5.

[0047] Finally, please see Figure 9 and Figure 13 After the sealing ring 24 is fitted onto the connecting post 23, the connecting post 23 is rotated first to make the threaded connection between the connecting post 23 and the upright post 3 reach a certain depth for pre-connection. At this time, the male head post 41 and the female head post 51 are coaxial. As the connecting post 23 continues to rotate, the lower end of the male head post 41 rotates relative to the female head post 51 and gradually inserts into the female head post 51 until the male head positive ring 44 and the male head negative ring 46 are engaged with the female head positive ring 54 and the female head negative ring 56 one by one.

[0048] Therefore, after assembly, the male connector 41 can be electrically connected to the female connector 51, realizing the electrical connection between the two wire harnesses. During the assembly process, the male connector 41 rotates relative to the female connector 51, preventing the wire harnesses at both ends from twisting, avoiding damage to the wire harnesses, and improving the reliability of the device.

[0049] In addition to the DC combiner box, the pole 3 also includes a solar controller, battery, inverter, data processing module, communication module, storage module, sensors, and main control chip, as described in the background section. This invention does not modify the aforementioned device; those skilled in the art can determine its design based on existing products or prior art, and therefore will not elaborate further.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
