Description

Technical Field

[0001] This utility model relates to the technical field of internal support structure of tubular soil moisture monitoring instruments, and in particular to a support for internal circuit components of a tubular soil moisture monitoring instrument that is connected by threads. Background Technology

[0002] Soil moisture monitoring is one of the core technologies in precision agriculture, ecological protection, and disaster early warning. Traditional soil moisture detection methods (such as the oven drying method and the tensiometer method) have problems such as poor real-time performance and damage to soil structure, while soil moisture monitoring equipment based on electronic sensors is gradually becoming the mainstream.

[0003] The tubular soil moisture monitor is an intelligent agricultural device used to monitor key parameters such as soil moisture and temperature in real time. Its core design adopts a multi-layered tubular structure, which is inserted vertically into the soil to achieve continuous and layered measurement of soil moisture at different depths (such as 0-100cm), providing a scientific basis for precision irrigation, crop growth regulation and water resource management.

[0004] In recent years, many manufacturers have tried to use tubular structures to achieve layered monitoring, but their internal circuit component fixing schemes still have obvious shortcomings.

[0005] Currently, there are two main methods for fixing the internal circuit components of tubular soil moisture monitoring instruments:

[0006] 1. Fix the circuit board and the matching humidity metal sensing ring on the flat guide rail (the width of the guide rail is less than the inner diameter of the PVC) according to the segmented detection requirements. Then insert the guide rail into the PVC pipe and use the humidity metal sensing ring to support it by tightly adhering to the PVC pipe wall.

[0007] 2. Make a hole in the outer PVC pipe wall, fix the internal circuit components with external screws, and then seal the entire PVC pipe with glue.

[0008] Both of the above methods have unresolved technical pain points:

[0009] Method 1's circuit component mounting method has very high installation requirements. First, the distance between the circuit components on the guide rail must be accurate. Second, the circuit board on the guide rail needs to be fixed with multiple screws. To avoid interference from metal screws on data acquisition, a common practice is to use nylon screws reinforced with hot melt adhesive. Additionally, fixing the two metal sensing rings required for humidity detection to the guide rail is also very complex, requiring multiple clips. The entire assembly process is very cumbersome and complex, and it cannot guarantee good shock resistance. Vibrations caused by agricultural machinery operation or soil subsidence could potentially cause the electronic components to detach from the guide rail.

[0010] Without considering aesthetics, Method 2 is simpler to assemble than Method 1 (only one screw is needed for external positioning, and the circuit components are mainly fixed by the adhesive after potting) and has better shock resistance. However, potting inevitably makes heat dissipation difficult for the circuit board, and electronic components are prone to aging and equipment failure under long-term high-temperature environments. Repairing faulty equipment by removing the circuit components is extremely difficult, requiring the adhesive to be removed piece by piece or the external PVC pipe to be damaged, significantly increasing equipment maintenance costs.

[0011] In summary, there is an urgent need for a highly reliable, easy-to-maintain circuit component fixing structure that is compatible with tubular sensors, which can improve the long-term stability and data accuracy of soil moisture monitoring equipment while ensuring ease of assembly. Utility Model Content

[0012] The purpose of this invention is to provide a support bracket for the internal circuit components of a tubular soil moisture monitor that is connected by threads, which solves the problem that the conventional fixing structure of the internal circuit components of a tubular soil moisture monitor is inconvenient for disassembly, maintenance and installation.

[0013] To achieve the above objectives, this utility model provides a support bracket for the internal circuit components of a tubular soil moisture monitoring instrument via threaded connection, including a fixed cylinder and a support device. The support device includes a support cylinder, a first threaded cylinder, a second threaded cylinder, and a fixing component. The first threaded cylinder is fixedly installed at both ends of the fixed cylinder, and the second threaded cylinder is fixedly installed at both ends of the support cylinder. The first threaded cylinder and the second threaded cylinder are threadedly engaged. The fixing component is installed on the fixed cylinder, and the support cylinder has a support groove inside.

[0014] The fixing component includes a compression spring and a compression ring. One end of the compression spring is fixedly connected to the fixing cylinder. The compression ring is sleeved on the first threaded cylinder and fixedly connected to the other end of the compression spring.

[0015] The second threaded cylinder is provided with a slot and a protective support rod. The slot penetrates the second threaded cylinder. The protective support rod is fixedly installed on the second threaded cylinder and located in the slot.

[0016] The support cylinder is also provided with an opening that penetrates the support cylinder and is located on the side of the support cylinder near the support groove.

[0017] The first threaded cylinder is also provided with a protective ring gasket, which is fixedly installed at the end of the first threaded cylinder and close to the support groove.

[0018] This utility model discloses a support bracket for the internal circuit components of a tubular soil moisture monitor, which is connected by threads. In use, the circuit board is inserted from the upper end of the support cylinder into the support groove within the support cylinder. A humidity-sensing metal ring is nested on the outside of the second threaded cylinder and contacts the support cylinder. Then, the fixing cylinder is screwed onto the support cylinder. The locking between the first and second threaded cylinders completes the assembly of the support cylinder and the fixing cylinder. During this process, the first threaded cylinder secures the circuit board inserted into the support groove, while the compression spring drives the compression ring to secure the humidity-sensing metal ring. Finally, the combined structure of the support cylinder and the fixing cylinder is inserted into the PVC pipe of the tubular soil moisture monitor. The threaded locking between the first threaded cylinder on the fixing cylinder and the second threaded cylinder on the support cylinder allows for quick assembly and disassembly of the support cylinder and the fixing cylinder, facilitating maintenance of the circuit board within the support groove.

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] The embodiment of this application is as follows:

[0025] Please see Figure 1-2 , Figure 1 This is a schematic diagram of the overall structure of the internal circuit component support of a tubular soil moisture monitoring instrument using a threaded connection, according to this utility model. Figure 2 This is a structural schematic diagram of the support device of this utility model.

[0026] This utility model provides a support for the internal circuit components of a tubular soil moisture monitor using a threaded connection: it includes a fixing cylinder 101 and a support device. The support device includes a support cylinder 102, a first threaded cylinder 103, a second threaded cylinder 104, and a fixing component. The fixing component includes a compression spring 106 and a compression ring 107. The second threaded cylinder 104 is provided with a slot 108 and a protective support rod 109. The support cylinder 102 is also provided with an opening 110. The first threaded cylinder 103 is also provided with a protective ring pad 111. The aforementioned solution solves the problem that the conventional fixing structure of the internal circuit components of a tubular soil moisture monitor is inconvenient for disassembly, maintenance, and installation.

[0027] In this embodiment, the threaded engagement between the first threaded cylinder 103 on the fixed cylinder 101 and the second threaded cylinder 104 on the support cylinder 102 enables quick assembly and disassembly between the support cylinder 102 and the fixed cylinder 101, thereby facilitating the maintenance of the circuit board in the support groove 105.

[0028] The first threaded cylinder 103 is fixedly installed at both ends of the fixed cylinder 101, and the second threaded cylinder 104 is fixedly installed at both ends of the support cylinder 102. The first threaded cylinder 103 and the second threaded cylinder 104 are threadedly engaged. The fixing component is installed on the fixed cylinder 101. The support cylinder 102 is provided with a support groove 105. The first threaded cylinder 103 is an externally threaded cylinder, while the second threaded cylinder 104 is an internally threaded cylinder. The support groove 105 facilitates the installation and fixing of the circuit board. The fixing component facilitates the fixing of the humidity sensing metal ring nested on the second threaded cylinder 104. The threaded engagement between the first threaded cylinder 103 on the fixed cylinder 101 and the second threaded cylinder 104 on the support cylinder 102 enables quick assembly and disassembly between the support cylinder 102 and the fixed cylinder 101, thereby facilitating the maintenance of the circuit board within the support groove 105.

[0029] Secondly, one end of the compression spring 106 is fixedly connected to the fixed cylinder 101; the compression ring 107 is sleeved on the first threaded cylinder 103 and fixedly connected to the other end of the compression spring 106. There are six sets of compression springs 106, which are distributed in a ring around the outside of the fixed cylinder 101. The compression ring 107 is a circular ring structure. The inner diameter of the compression ring 107 is larger than the outer diameter of the second threaded cylinder 104. The compression ring 107 is made of plastic. The compression spring 106 pushes the compression ring 107 against the humidity sensing metal ring on the support cylinder 102, thereby facilitating the fixation of the humidity sensing metal ring.

[0030] Furthermore, the slot 108 penetrates the second threaded cylinder 104; the protective support rod 109 is fixedly installed on the second threaded cylinder 104 and located within the slot 108. The slot 108 facilitates the passage of the connecting copper wire between the circuit board and the humidity sensing metal ring. The protective support rod 109 has an arc-shaped structure, which helps to protect the copper wire and prevent it from being crushed.

[0031] Furthermore, the opening 110 penetrates the support cylinder 102. The opening 110 is located on the side of the support cylinder 102 near the support groove 105. The opening 110 has a circular structure. The opening 110 facilitates the extension of the temperature probe from the circuit board and close contact with the inner wall of the PVC pipe of the tubular soil moisture monitor, ensuring the accuracy of temperature sensing.

[0032] Finally, the protective ring pad 111 is fixedly installed at the end of the first threaded cylinder 103 and close to the support groove 105. The protective ring pad 111 is made of rubber. The protective ring pad 111 is provided to prevent the first threaded cylinder 103 from damaging the circuit board in the support groove 105.

[0033] In this embodiment, during use, the circuit board is inserted from the upper end of the support cylinder 102 into the support groove 105 within the support cylinder 102, and the humidity-sensing metal ring is nested on the outside of the second threaded cylinder 104 and in contact with the support cylinder 102. Then, the fixing cylinder 101 is screwed onto the support cylinder 102. The support cylinder 102 and the fixing cylinder 101 are assembled through the locking between the first threaded cylinder 103 and the second threaded cylinder 104. During this process, the first threaded cylinder 103 is inserted into the support groove 105. The circuit board is fixed, and the compression spring 106 drives the compression ring 107 to fix the humidity sensing metal ring. Finally, the combined structure of the support cylinder 102 and the fixing cylinder 101 is inserted into the PVC pipe of the tubular soil moisture monitor. The threaded engagement between the first threaded cylinder 103 on the fixing cylinder 101 and the second threaded cylinder 104 on the support cylinder 102 enables quick assembly and disassembly of the support cylinder 102 and the fixing cylinder 101, thereby facilitating the maintenance of the circuit board in the support groove 105.

[0034] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
