Description

Technical Field

[0001] This utility model relates to the field of water stress monitoring technology, specifically a crop water stress monitoring device. Background Technology

[0002] In numerous fields such as agricultural production, ecological environment research, and geological exploration, accurate monitoring of soil moisture is crucial for understanding crop growth environments, assessing ecosystem balance, and grasping geological characteristics. Soil moisture sensors, as key tools for achieving this monitoring objective, directly impact the accuracy and validity of monitoring data through their stability and reliability.

[0003] Currently, some existing monitoring devices on the market lack effective protective structures, leaving the detection probes directly exposed. During daily use, transportation, and storage, the detection probes are highly susceptible to external physical damage, such as impacts and scratches. This not only affects the appearance of the detection probes but also damages their internal structure and performance, leading to a decrease in detection accuracy. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a crop water stress monitoring device that solves the problem of the detection probe being easily damaged by external influences.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a crop water stress monitoring device, comprising a protective shell and a flip-top cover rotatably connected to the outside of the protective shell. A guide rod is fixedly connected to the inner side of the protective shell, and a mounting shell is slidably connected to the outer wall of the guide rod. Tension springs are fixedly connected to both sides of the mounting shell. A soil moisture sensor is snapped into the inner side of the mounting shell, and a detection probe is fixedly connected to the bottom of the soil moisture sensor. A limit assembly is fixedly connected to the top of the protective shell. The device also includes an opening and closing assembly, the bottom of which is connected to the inner side of the protective shell. The bottom of the wall is fixedly connected. The opening and closing assembly includes a fixed cylinder. A top rod is slidably connected to the inner wall of the fixed cylinder. A compression spring is fixedly connected to the bottom of the top rod. Movable rods are rotatably connected to both sides of the top rod. An opening and closing cover plate is rotatably connected to the bottom end of the movable rod. A limit rod is slidably connected to the top of the opening and closing cover plate. When the mounting shell pushes the top rod downward, the compression spring is compressed in the fixed cylinder. At this time, the downward-moving top rod can push the opening and closing cover plates on both sides outward through the movable rods. Under the restriction of the limit rod, the opening and closing cover plates on both sides move in opposite directions, so that the sliding hole opened at the bottom of the protective shell is exposed.

[0008] Preferably, the top end of the tension spring is fixedly connected to the top of the inner wall of the protective shell, and the bottom end of the limiting component is rotatably connected to the top of the mounting shell. When the mounting shell moves downward along the guide rod, the tension spring is stretched by force.

[0009] Preferably, the bottom of the fixed cylinder is fixedly connected to the bottom of the inner wall of the protective shell, the bottom end of the compression spring is fixedly connected to the inner side of the fixed cylinder, the bottom of the opening and closing cover is slidably connected to the bottom of the protective shell, and both ends of the limiting rod are fixedly connected to the inner wall of the protective shell. When the detection probe is stored in the protective shell, the opening and closing cover is in a closed state, which can effectively prevent the detection probe from being physically damaged by the outside world, and at the same time prevent dust, debris and other things from adhering to the detection probe and prevent moisture corrosion, thereby ensuring the stable performance of the detection probe and extending its service life.

[0010] Preferably, the limiting component includes a limiting cylinder, the inner wall of which is slidably connected to a push rod, and the outer wall of the push rod is fixedly connected to a limiting block. When the push rod drives the mounting shell to move downward along the guide rod, the soil moisture sensor moves together with the mounting shell and drives the detection probe to slide out from the protective shell.

[0011] Preferably, the outer wall of the limiting block is slidably connected to the inner wall of the limiting cylinder through a limiting groove, and the limiting groove is opened in the wall of the limiting cylinder. When the limiting block enters the limiting cylinder through the limiting groove, the knob is rotated to cause the push rod to drive the limiting block to deflect inside the limiting cylinder. At this time, the limiting block and the limiting groove are misaligned, and the limiting block cannot be removed from the limiting cylinder.

[0012] Preferably, a knob is fixedly connected to the top of the push rod, the outer wall of the limiting cylinder is fixedly connected to the top of the protective shell, and the bottom end of the push rod is rotatably connected to the top of the mounting shell. Pushing the knob in the limiting assembly downwards can cause the push rod to drive the mounting shell to move downwards along the guide rod.

[0013] (III) Beneficial Effects

[0014] This invention provides a crop water stress monitoring device. It has the following beneficial effects:

[0015] (I) By setting a limiting component, when the limiting block enters the limiting cylinder through the limiting groove, the knob is turned so that the push rod drives the limiting block to deflect inside the limiting cylinder. At this time, the limiting block and the limiting groove are misaligned, and the limiting block cannot be removed from the limiting cylinder. This can prevent the tension spring from driving the mounting shell to reset during the detection process, and ensure that the detection probe can be stably placed at a suitable depth in the soil, providing stable physical conditions for accurate detection of soil moisture.

[0016] (II) By setting up an opening and closing component, when the detection probe is stored in the protective shell, the opening and closing cover is in a closed state, which can effectively prevent the detection probe from being physically damaged by the outside world. At the same time, it can also prevent dust, debris and other things from adhering to the detection probe and prevent moisture erosion, thereby ensuring the stable performance of the detection probe and extending its service life.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figure 1-4This utility model provides a technical solution: a crop water stress monitoring device, including a protective shell 1 and a flip cover 2 rotatably connected to the outside of the protective shell 1. A guide rod 3 is fixedly connected to the inner side of the protective shell 1, and a mounting shell 4 is slidably connected to the outer wall of the guide rod 3. Tension springs 5 ​​are fixedly connected to both sides of the mounting shell 4. A soil moisture sensor 6 is snapped into the inner side of the mounting shell 4. A detection probe 7 is fixedly connected to the bottom of the soil moisture sensor 6. A limit component 9 is fixedly connected to the top of the protective shell 1. This monitoring device mainly uses the protective shell 1 to protect the soil moisture sensor 6. When the soil moisture sensor 6 is in use, open the flip cover 2, snap the soil moisture sensor 6 into the mounting housing 4, and then reset the flip cover 2. The system also includes an opening and closing assembly 8, the bottom of which is fixedly connected to the bottom of the inner wall of the protective housing 1. The opening and closing assembly 8 includes a fixed cylinder 81, a push rod 82 slidably connected to the inner wall of the fixed cylinder 81, a compression spring 83 fixedly connected to the bottom of the push rod 82, movable rods 84 rotatably connected to both sides of the push rod 82, an opening and closing cover 85 rotatably connected to the bottom of the movable rod 84, a limit rod 86 slidably connected to the top of the opening and closing cover 85, and a tension spring 5 with its top end rotatably connected to the inner wall of the protective housing 1. The top is fixedly connected, the bottom of the limiting component 9 is rotatably connected to the top of the mounting shell 4, the bottom of the fixed cylinder 81 is fixedly connected to the bottom of the inner wall of the protective shell 1, the bottom end of the compression spring 83 is fixedly connected to the inner side of the fixed cylinder 81, the bottom of the opening and closing cover plate 85 is slidably connected to the bottom of the protective shell 1, and both ends of the limiting rod 86 are fixedly connected to the inner wall of the protective shell 1. During the process of the mounting shell 4 driving the soil moisture sensor 6 downwards, when the bottom of the mounting shell 4 contacts the top rod 82 in the opening and closing component 8, the mounting shell 4 pushes the top rod 82 downwards, causing the compression spring 83 to be compressed within the fixed cylinder 81. When the top rod 82 moves downward, it can push the opening and closing cover plates 85 on both sides outward through the movable rod 84. Under the restriction of the limiting rod 86, the opening and closing cover plates 85 on both sides move in the opposite direction, so that the sliding hole opened at the bottom of the protective shell 1 is exposed. At this time, the downward moving detection probe 7 can slide out of the protective shell 1 through the sliding hole. When the detection probe 7 is stored in the protective shell 1, the opening and closing cover plate 85 is in a closed state, which can effectively prevent the detection probe 7 from being physically damaged by the outside, and at the same time prevent dust, debris and other things from adhering to the detection probe 7, prevent moisture corrosion, thereby ensuring the stable performance of the detection probe 7 and extending its service life.

[0024] The limiting assembly 9 includes a limiting cylinder 91, a push rod 92 slidably connected to the inner wall of the limiting cylinder 91, a limiting block 93 fixedly connected to the outer wall of the push rod 92, and the outer wall of the limiting block 93 slidably connected to the inner wall of the limiting cylinder 91 through a limiting groove 94, which is formed in the wall of the limiting cylinder 91. A knob 95 is fixedly connected to the top of the push rod 92, the outer wall of the limiting cylinder 91 is fixedly connected to the top of the protective shell 1, and the bottom end of the push rod 92 is rotatably connected to the top of the mounting shell 4. Pushing the knob 95 in the limiting assembly 9 downward causes the push rod 92 to move the mounting shell 4 downward along the guide rod 3. At this time, the soil moisture sensor 6 moves together with the mounting shell 4. This causes the detection probe 7 to slide out of the protective shell 1, at which point it can be inserted into the soil for detection. During this process, the tension spring 5 is stretched. When the limiting block 93 enters the limiting cylinder 91 through the limiting groove 94, the knob 95 is turned, causing the push rod 92 to deflect the limiting block 93 within the limiting cylinder 91. At this point, the limiting block 93 and the limiting groove 94 are misaligned, and the limiting block 93 cannot be dislodged from the limiting cylinder 91. This prevents the tension spring 5 from resetting the mounting shell 4 during the detection process, ensuring that the detection probe 7 can be stably positioned at a suitable depth in the soil, providing stable physical conditions for accurate soil moisture detection.

[0025] Working principle: The monitoring device mainly uses the protective shell 1 to protect the soil moisture sensor 6. When installing the soil moisture sensor 6, open the flip cover 2, snap the soil moisture sensor 6 into the installation shell 4, and then reset the flip cover 2.

[0026] When in use, push the knob 95 in the limiting component 9 downwards, so that the push rod 92 drives the mounting shell 4 to move downwards along the guide rod 3. At this time, the soil moisture sensor 6 moves together with the mounting shell 4 and drives the detection probe 7 to slide out from the protective shell 1. Then the detection probe 7 can be inserted into the soil for detection.

[0027] During this process, the tension spring 5 is stretched. When the limiting block 93 enters the limiting cylinder 91 through the limiting groove 94, the knob 95 is rotated, causing the push rod 92 to drive the limiting block 93 to deflect within the limiting cylinder 91. At this time, the limiting block 93 and the limiting groove 94 are misaligned, and the limiting block 93 cannot be dislodged from the limiting cylinder 91. This prevents the tension spring 5 from driving the mounting shell 4 to reset during the detection process, ensuring that the detection probe 7 can be stably positioned at a suitable depth in the soil, providing stable physical conditions for accurate soil moisture detection.

[0028] During the downward movement of the soil moisture sensor 6 driven by the mounting shell 4, when the bottom of the mounting shell 4 contacts the top rod 82 in the opening and closing assembly 8, the mounting shell 4 pushes the top rod 82 downward, causing the compression spring 83 to be compressed within the fixed cylinder 81. At this time, the downward-moving top rod 82 can push the opening and closing cover plates 85 on both sides outward through the movable rod 84. Under the restriction of the limiting rod 86, the opening and closing cover plates 85 on both sides move in the opposite direction, causing the sliding hole at the bottom of the protective shell 1 to be exposed. At this time, the downward-moving detection probe 7 can slide out of the protective shell 1 through the sliding hole. When the detection probe 7 is stored inside the protective shell 1, the opening and closing cover plate 85 is in a closed state, which can effectively prevent the detection probe 7 from being physically damaged by the outside, and at the same time prevent dust, debris, etc. from adhering to the detection probe 7, preventing moisture erosion, thereby ensuring the stable performance of the detection probe 7 and extending its service life.
