Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically to an environmental monitoring sensor. Background Technology

[0002] As people's living standards improve, their requirements for food are getting higher and higher. People are beginning to prefer green foods, such as vegetables, fruits and other agricultural products. However, these vegetables and fruits need specific environmental conditions to grow. Therefore, greenhouse cultivation has emerged. Greenhouse cultivation creates an environment suitable for the growth of vegetables, fruits and other agricultural products in a closed environment.

[0003] Chinese patent CN210922702U discloses an environmental monitoring sensor. This sensor allows the protective cover to be slightly lowered, then the lever to be rotated so that the lever and the groove are aligned on the same vertical axis. The protective cover is then slowly released, causing it to rise under the force of a spring, extending the telescopic rod to allow air to pass through and facilitate air exchange. When not in use, the protective cover is pressed down, exposing the lever in the groove. Rotating the lever until it crosses the groove completely blocks the air vent, preventing dust from entering and thus avoiding interference with the device's operation.

[0004] The applicant discovered the following technical problems when implementing the above-mentioned technical solution:

[0005] When using this device, the sensor probe is prone to low contact with the soil, resulting in inaccurate monitoring data.

[0006] Therefore, providing an environmental monitoring sensor that can be further inserted into the soil after several sensor probes have been inserted into the soil, thereby improving the accuracy of monitoring data, is a problem that this utility model urgently needs to solve. Utility Model Content

[0007] To address the aforementioned technical problems, the purpose of this invention is to overcome the issue that existing devices often suffer from low contact between the sensor probes and the soil, leading to inaccurate monitoring data. Therefore, this invention provides an environmental monitoring sensor that can further penetrate the soil after several sensor probes have already been inserted, thereby improving the accuracy of the monitoring data.

[0008] To achieve the above objectives, this utility model provides an environmental monitoring sensor, comprising: a mounting frame, a plug, and a driving assembly. A plug tube and a sensor probe assembly disposed inside the plug tube are vertically arranged below the mounting frame. A plurality of guide holes are arranged around the periphery of the plug tube. A second limiting block is coaxially arranged in each guide hole. Several groups of sensor probe assemblies are provided, each disposed within a guide hole. Each sensor probe assembly includes: a sensor probe body, a guide rod, a first limiting ring block, an arc-shaped block, and an elastic element. The sensor probe body is adapted to the guide hole and coaxially disposed within the guide hole. The guide rod is coaxially disposed within the guide hole. A shaft is located at one end of the sensor probe body near the inside of the insertion tube, and its diameter is adapted to the inner diameter of the second limiting ring block. The first limiting ring block is coaxially mounted on the guide rod. The arc-shaped block is located at one end of the guide rod away from the sensor probe body. The elastic element is sleeved on the guide rod, and one end of it abuts or is fixed to the first limiting ring block, and the other end abuts or is fixed to the second limiting ring block. The two ends of each arc-shaped block are connected to form a circular hole. The insertion post is coaxially and vertically mounted inside the insertion tube, and its lower end is provided with a mating cone head adapted to the circular hole, and its upper end is provided with a limiting component for limiting the rotation of the insertion post. The drive component is mounted on the mounting frame, and its output end is coaxially threaded into the insertion post.

[0009] Preferably, the limiting component includes: a limiting plate horizontally disposed on the upper end of the insertion post and a limiting post vertically disposed on the mounting frame, wherein the upper end of the limiting post passes through the limiting plate.

[0010] Preferably, the drive assembly includes: a drive motor mounted on the mounting frame and a lead screw coaxially mounted on the output end of the drive motor. The upper surface of the insert has an internal thread groove coaxially recessed to match the lead screw, and the lead screw is coaxially threaded into the internal thread groove.

[0011] Preferably, the mounting frame is further provided with a sensor assembly that is signal-connected to each sensor probe body.

[0012] Preferably, the part of the arc-shaped block that contacts the mating cone has rounded corners.

[0013] Preferably, the lower end of the cannula is provided with an insertion cone.

[0014] Preferably, the width of the sensor probe body is greater than the inner diameter of the second limiting ring block.

[0015] Preferably, the sensor assembly includes: a temperature and humidity sensor, a soil moisture sensor, a soil temperature sensor, a soil pH sensor, etc.

[0016] According to the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: This application uses a drive assembly to move the insertion post up and down within the insertion tube. When passing through the circular hole, the conical head contacts each arc-shaped block, causing each arc-shaped block to move along the length of its corresponding guide rod and compress the elastic element. This, in turn, drives the sensor probe body to extend out of the side wall of the insertion tube and insert into the soil, thereby improving the accuracy of monitoring data acquisition. The sensor probe assemblies are respectively arranged in multiple guide holes around the insertion tube, with one sensor probe assembly in each guide hole. This design enables multi-point monitoring of the environment, improving the comprehensiveness and accuracy of monitoring. The limiting assembly restricts the rotation of the insertion post, ensuring that the insertion post can extend and retract under the drive of the drive assembly. The design of the guide rod and the limiting ring block ensures that the sensor probe body can stably extend out of the guide hole and insert into the soil.

[0031] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7 An environmental monitoring sensor includes: a mounting frame 1, a plug 2, and a drive assembly 3. A plug tube 101 and a sensor probe assembly 102 disposed inside the plug tube 101 are vertically arranged below the mounting frame 1. A plurality of guide holes 10101 are arranged around the periphery of the plug tube 101. A second limiting block is coaxially arranged in each guide hole 10101. Several sets of sensor probe assemblies 102 are respectively disposed within each guide hole 10101. Each sensor probe assembly 102 includes: a sensor probe body 10201, a guide rod 10202, a first limiting ring block 10203, an arc-shaped block 10204, and an elastic element 10205. The sensor probe body 10201 is adapted to and coaxially disposed within the guide holes 10101. The guide rod 10202 is coaxially disposed within the sensor probe body 10201. 201 is located near the inner end of the insertion cannula 101, and its diameter is adapted to the inner diameter of the second limiting ring block 10102. The first limiting ring block 10203 is coaxially mounted on the guide rod 10202. The arc-shaped block 10204 is located at the end of the guide rod 10202 away from the sensor probe body 10201. The elastic element 10205 is sleeved on the guide rod 10202, and one end of it abuts or is fixed to the first limiting ring block 10203, while the other end is connected to the first limiting ring block 10202. Two limiting ring blocks 10102 abut or fix; each arc-shaped block 10204 has two ends connected to form a circular hole 1020402; the insertion post 2 is coaxially and vertically arranged in the insertion tube 101, and its lower end is provided with a mating cone head 201 adapted to the circular hole 1020402, and its upper end is provided with a limiting component 202 for limiting the rotation of the insertion post 2; the driving component 3 is arranged on the mounting frame 1, and its output end is coaxially threaded into the insertion post 2.

[0033] This application utilizes the activation of the drive assembly 3 to move the insertion post 2 up and down within the insertion tube 101. As it passes through the circular hole 1020402, it contacts each arc-shaped block 10204 through the engagement of the cone head 201. This causes each arc-shaped block 10204 to move along the length of its corresponding guide rod 10202, compressing the elastic element 10205, and ultimately driving the sensor probe body 10201 to extend out of the side wall of the insertion tube 101 and insert into the soil, thereby improving the accuracy of monitoring data acquisition. Sensor probe assemblies 102 are respectively disposed within multiple guide holes 10101 around the insertion tube 101, with one sensor probe assembly 102 in each guide hole 10101. This design enables multi-point environmental monitoring, improving the comprehensiveness and accuracy of the monitoring. The limiting assembly 202 restricts the rotation of the insertion post 2, ensuring that the insertion post 2 can extend and retract under the drive of the drive assembly 3. The design of the guide rod 10202 and the limiting ring block ensures that the sensor probe body 10201 can stably extend out of the guide hole 10101 and insert into the soil.

[0034] Reference Figure 4 The limiting component 202 includes: a limiting plate 20201 horizontally disposed on the upper end of the insert post 2 and a limiting post 20202 vertically disposed on the mounting frame 1, wherein the upper end of the limiting post 20202 passes through the limiting plate 20201.

[0035] This design restricts the rotation of the insertion post 2 to ensure that the insertion post 2 can extend and retract under the drive of the drive assembly 3.

[0036] Reference Figure 2 , Figure 5 and Figure 6 The drive assembly 3 includes a drive motor 301 mounted on the mounting frame 1 and a lead screw 302 coaxially mounted on the output end of the drive motor 301. The upper surface of the insert 2 is coaxially recessed with an internal thread groove 203 that is adapted to the lead screw 302. The lead screw 302 is coaxially threaded into the internal thread groove 203.

[0037] This application uses a drive motor 301 to rotate a lead screw 302, which in turn drives the insertion post 2 to rise and fall. The upper surface of the insertion post 2 is provided with an internal thread groove 203, which is adapted to the lead screw 302. The lead screw 302 can be coaxially threaded into the internal thread groove 203. This design can ensure the stability and accuracy of the drive, while also facilitating installation and adjustment.

[0038] Reference Figure 3 and Figure 4 The mounting frame 1 is also provided with a sensor assembly 103 that is signal-connected to each sensor probe body 10201.

[0039] The sensor assembly 103 mounted on the mounting frame 1 of this application is connected to the signal of each sensor probe body 10201, enabling signal transmission and communication between the sensor probe body 10201 and other components. The sensor assembly 103 is responsible for the signal connection of the sensor probe body 10201, transmitting the data collected by the sensor to other systems or devices for processing and analysis.

[0040] Reference Figure 8 The arc-shaped block 10204 and the contact portion of the mating cone 201 are provided with a rounded corner 1020401.

[0041] The arc-shaped block 10204 and the mating cone 201 of this application are provided with a fillet 1020401. The fillet 1020401 can reduce the sharp edges of the contact surface, reduce stress concentration, improve the smoothness and stability of the contact surface, and also help to improve the durability and service life of the parts.

[0042] Reference Figure 4 The lower end of the insertion tube 101 is provided with an insertion cone 10103.

[0043] The insertion cone 10103 of this application is located at the lower end of the insertion tube 101 so as to open the circular hole 1020402 to drive the arc block 10204.

[0044] Reference Figure 3 The width of the sensor probe body 10201 is greater than the inner diameter of the second limiting ring block 10102.

[0045] The width of the sensor probe body 10201 in this application is greater than the inner diameter of the second limiting ring block 10102, which can effectively limit the position of the sensor during the installation process and ensure that the sensor probe body 10201 can be correctly installed in the limiting ring block, avoiding positional deviation or falling off.

[0046] Reference Figure 4 The sensor assembly 103 includes: a temperature and humidity sensor, a soil moisture sensor, a soil temperature sensor, a soil pH sensor, etc.

[0047] The sensor assembly 103 of this application includes a variety of sensors that can simultaneously monitor different environmental parameters, such as temperature, humidity, soil moisture, soil temperature and soil pH, providing comprehensive environmental monitoring information.

[0048] In use, the device provided by this utility model activates the drive assembly 3 to move the insertion post 2 up and down within the insertion tube 101. As it passes through the circular hole 1020402, it contacts each arc-shaped block 10204 through the engaging cone head 201, thereby causing each arc-shaped block 10204 to move along the length of its corresponding guide rod 10202 and compress the elastic element 10205. This, in turn, drives the sensor probe body 10201 to extend out of the side wall of the insertion tube 101 and insert into the soil, thus improving the accuracy of monitoring data acquisition. Sensor probe assemblies 102 are respectively disposed within multiple guide holes 10101 around the insertion tube 101, with each guide hole 10101 containing one sensor probe assembly 102. This design enables multi-point environmental monitoring, improving the comprehensiveness and accuracy of the monitoring. The limiting assembly 202 restricts the rotation of the insertion post 2, ensuring that the insertion post 2 can extend and retract under the drive of the drive assembly 3. The guide rod 10202 and the limiting ring block are designed to ensure that the sensor probe body 10201 can stably extend out of the guide hole 10101 and be inserted into the soil.
