Description
Technical Field
[0001] This utility model relates to the field of environmental monitoring technology, specifically a real-time humidity monitoring device. Background Technology
[0002] Soil moisture, also known as soil water content, is a physical quantity that indicates the degree of dryness or wetness of soil. It is a relative variable of soil moisture content and is usually expressed as a percentage of soil moisture content to dry soil weight, also known as soil mass temperature. If expressed as a percentage of soil moisture to total soil volume, it is called soil volumetric moisture. Soil moisture usually refers to mass moisture. There is also a method that uses soil moisture content as a percentage of field capacity to express the degree of soil moisture, called relative soil moisture. When in contact with the ground, it needs to be supported, but the fixation is not stable. If there is any deviation, it will affect the detection results.
[0003] Utility model CN215005371U discloses a soil moisture detection device, including a soil moisture detector. A sleeve is mounted on the outer wall of the soil moisture detector, and side rods are symmetrically fixedly connected to the outer wall of the sleeve. A base plate is fixedly connected to the bottom side wall of the side rods, and the inner cavity of the base plate is clearance-fitted with the soil moisture detector. This utility model provides a soil moisture detection device where, when inserted into the soil, the base plate can fit against the ground, supporting the soil moisture detector and making its placement more stable. This prevents instability during detection, avoids displacement that could affect the detection results, and allows for more stable detection.
[0004] However, the existing technology has its shortcomings in use: the probe on the soil tester is a long rod-shaped structure, which means that when stored, the probe lacks a protective structure and is easily damaged, affecting its use.
[0005] Therefore, this utility model provides a real-time humidity monitoring device. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a real-time humidity monitoring device to solve the problems mentioned in the background technology. This utility model can effectively isolate the probe when the detector body is not in use and is stored, so as to avoid the probe being damaged by collision and improve the convenience of storage. Moreover, it has the advantage of more stable and reliable fixation when adapting.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a real-time humidity monitoring device, comprising a detector body, a probe rod at the bottom of the detector body, a positioning sleeve fixedly fitted on the probe rod near the top, a guide sleeve on the outer side of the positioning sleeve, the middle of the outer side of the guide sleeve being rotatably connected to the positioning sleeve, and the rotation axes of both being perpendicular to the axes of the positioning sleeve and the guide sleeve, an extension tube being slidably fitted inside the guide sleeve, a sliding rod fitted at one end of the extension tube, a protective sleeve parallel to the sliding rod on one side, one end of the protective sleeve being fixedly connected to one end of the sliding rod, and the sliding rod and the extension tube being rotatably engaged.
[0008] Furthermore, a plug sleeve is fixedly connected to the bottom of the positioning sleeve, and the other end of the protective sleeve is inserted into the plug sleeve.
[0009] Furthermore, a positioning shaft is fixedly connected to the middle of the outer arc surface of the guide sleeve, and a limiting sleeve sleeved outside the positioning shaft is fixedly connected to the outer peripheral wall of the positioning sleeve. The limiting sleeve and the positioning shaft are rotatably connected.
[0010] Furthermore, a locking bolt is screwed through the outer peripheral wall of the limiting sleeve, and one end of the locking bolt is opposite to the outer peripheral wall of the positioning shaft.
[0011] Furthermore, a screwing block is fixedly connected to the other end of the locking bolt.
[0012] Furthermore, the extension tube is provided with insert rods near both ends on its exterior. One end of each insert rod is rotatably connected to the outer peripheral wall of the extension tube. When the extension tube is horizontally distributed and perpendicular to the insert rod, the insert rod is in a vertical state.
[0013] Furthermore, the extension tube is fitted with a friction-increasing rubber sleeve that rubs against the slide rod.
[0014] The beneficial effects of this utility model are as follows:
[0015] In this invention, a guide sleeve is rotatably installed outside the positioning sleeve, and an extension tube is fitted inside the guide sleeve. One end of the extension tube is axially slidably connected to a slide rod, and a protective sleeve is installed parallel to one side of the slide rod. Thus, by sliding the slide rod, the protective sleeve can be fitted over the probe rod, thereby isolating and protecting the probe rod and improving the convenience of storage.
[0016] In this invention, the extension tube and the guide sleeve are axially slidably configured. The guide sleeve is rotated until the extension tube is in a horizontal state, and then the extension tube is slid so that the guide sleeve is located in the middle of the extension tube. At this time, the extension tube can stably support the guide sleeve, thereby improving the stability of the insertion of the rod and the soil. Attached Figure Description

[0021] 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.
[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a real-time humidity monitoring device, including a detector body 1, a probe 11 at the bottom of the detector body 1, a positioning sleeve 2 fixedly sleeved on the probe 11 near the top, a guide sleeve 3 on the outer side of the positioning sleeve 2, the middle of the outer side of the guide sleeve 3 and the positioning sleeve 2 being rotatably connected, and the rotation axis of both being perpendicular to the axes of the positioning sleeve 2 and the guide sleeve 3. Specifically, a positioning shaft 31 is fixedly connected to the middle of the outer arc surface of the guide sleeve 3, and a limiting sleeve 21 sleeved outside the positioning shaft 31 is fixedly connected to the outer peripheral wall of the positioning sleeve 2. The limiting sleeve 21 and the positioning shaft 31 are rotatably connected, so that the guide sleeve 3 can rotate to a state perpendicular to the probe 11 and also to a state parallel to the probe 11.
[0023] An extension tube 4 is slidably fitted inside the guide sleeve 3. The extension tube 4 can move axially relative to the guide sleeve 3. A slide rod 5 is fitted onto one end of the extension tube 4. A protective sleeve 6 parallel to the slide rod 5 is provided on one side of the slide rod 5. One end of the protective sleeve 6 is fixedly connected to one end of the slide rod 5. When the slide rod 5 slides outward relative to the extension tube 4, it can drive the protective sleeve 6 to move synchronously. Specifically, a connecting arm can be welded to one end of the slide rod 5. One end of the connecting arm is fixedly connected to the protective sleeve 6. The function of the protective sleeve 6 is to protect the probe rod 11 when it is fitted outside the probe rod 11. Among them, a plug sleeve 22 is fixedly connected to the bottom of the positioning sleeve 2. The other end of the protective sleeve 6 is inserted into the plug sleeve 22. When the other end of the protective sleeve 6 is fitted into the plug sleeve 22, the protective strength of the protective sleeve 6 is greatly improved.
[0024] The sliding arrangement of the extension tube 4 relative to the guide sleeve 3 facilitates the movement of the extension tube 4. In other words, when the extension tube 4 is in a horizontal state, sliding the extension tube 4 can make it and the probe rod 11 form a cross. When the bottom of the probe rod 11 is inserted into the soil, the extension tube 4 contacts the soil surface. At this time, the extension tube 4 plays a role in stabilizing and supporting the detector body 1.
[0025] In this embodiment, the sliding rod 5 and the extension tube 4 are rotatably engaged. To satisfy the functions of rotational and sliding engagement between the sliding rod 5 and the extension tube 4, a friction-enhancing rubber sleeve 8 is nested inside the extension tube 4 to engage with the sliding rod 5. That is, the circular hole inside the extension tube 4 and the sliding rod 5 are separated by the friction-enhancing rubber sleeve 8, which applies resistance to the movement of the sliding rod 5. The purpose of the rotatable engagement between the sliding rod 5 and the extension tube 4 is to facilitate the movement of the protective sleeve 6 and to prevent the protective sleeve 6 from interfering with the probe 11 when the extension tube 4 is rotated to a horizontal position.
[0026] In this embodiment, a locking bolt 211 is screwed through the outer peripheral wall of the limiting sleeve 21. One end of the locking bolt 211 is opposite to the outer peripheral wall of the positioning shaft 31. When the locking bolt 211 is tightened, the positioning shaft 31 can be locked inside the limiting sleeve 21, thereby ensuring that the extension tube 4 and the probe 11 are in a vertical state. Furthermore, a screwing block 2111 is fixedly connected to the other end of the locking bolt 211. The screwing block 2111 is a handheld component that controls the rotation of the locking bolt 211.
[0027] It should be noted that, in practical use, a locking screw that is compatible with the extension tube 4 can be screwed through the outer wall of the guide sleeve 3 as needed. When the locking screw is tightened, the extension tube 4 can be fixed on the guide sleeve 3, thereby effectively preventing the extension tube 4 from moving axially unexpectedly.
[0028] In this embodiment, the extension tube 4 is provided with insertion rods 7 near both ends. One end of the insertion rod 7 is rotatably connected to the outer peripheral wall of the extension tube 4. Specifically, the outer peripheral wall of the extension tube 4 and one end of the insertion rod 7 are hinged. This rotatable arrangement facilitates the folding of the insertion rod 7 to reduce its space occupation. When the extension tube 4 is horizontally distributed and perpendicular to the insertion rod 7, the insertion rod 7 is in a vertical state, acting as an anchor. During use, it is inserted into the soil to improve the stability of the contact between the extension tube 4 and the ground.
[0029] Working principle: When this device is needed, manually pull the protective sleeve 6 outward, and slide the sliding rod 5 outward. When the protective sleeve 6 is disengaged from the probe rod 11, manually rotate the sliding rod 5 to make the protective sleeve 6 and the probe rod 11 misaligned. Then reset the sliding rod 5. At this time, the protective sleeve 6 is located on one side of the extension tube 4. Then move the extension tube 4 until it is perpendicular to the probe rod 11. Then tighten the locking bolt 211. At this time, the guide sleeve 3 is fixed. Then push the extension tube 4 axially and make its middle part face the positioning sleeve 2. Then unfold the insertion rod 7 on the extension tube 4 and insert the probe rod 11 into the soil. At the same time, the detector body 1 will be stably supported and limited by the extension tube 4 and the insertion rod 7.
[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
