Description

Technical Field

[0001] This utility model relates to the field of agricultural environmental monitoring technology, and in particular to a greenhouse temperature monitoring device. Background Technology

[0002] The core of agricultural facilities such as greenhouses and polytunnels lies in the precise control of environmental factors, among which temperature is one of the most critical parameters. Currently, the temperature monitoring equipment widely used in greenhouses mostly adopts a structure that places the sensor in a simple protective shell, which has obvious shortcomings: First, in order to prevent moisture, dust and pesticide corrosion, the protective shell is usually quite sealed, which causes the sensor to sense lag and cannot reflect the rapidly changing air temperature inside the greenhouse in real time and accurately, resulting in a "thermal lag" phenomenon; Second, the equipment is mostly fixed directly with screws, which is not easy to adjust after the installation position is fixed, and subsequent maintenance work such as battery replacement and sensor cleaning is extremely inconvenient; Third, the equipment is exposed to high temperature, high humidity and strong ultraviolet radiation environment for a long time, and the ordinary plastic shell is prone to aging. At the same time, the heat generated by the internal electronic components will also accumulate, causing "self-heating interference" to the temperature sensor and affecting the measurement accuracy. Therefore, we propose a greenhouse temperature monitoring device. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies. First, to prevent corrosion from moisture, dust, and pesticides, the protective casing is usually quite airtight, causing sensor lag and making it impossible to accurately reflect the rapidly changing air temperature inside the greenhouse in real time, resulting in a "thermal lag" phenomenon. Second, the equipment is mostly fixed with screws, making it difficult to adjust the installation position after it is fixed, and subsequent maintenance work such as battery replacement and sensor cleaning is extremely inconvenient. Third, the equipment is exposed to high temperature, high humidity, and strong ultraviolet radiation for a long time, which makes the ordinary plastic casing prone to aging. At the same time, the internal electronic components also generate heat, causing "self-heating interference" to the temperature sensor and affecting the measurement accuracy.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A greenhouse temperature monitoring device includes a main unit and a fixed base. The main unit is mounted on the fixed base, which is fixedly mounted on a wall or column inside the greenhouse. The main unit has a dome-shaped cover on top. The lower side wall of the dome-shaped cover has several air inlets, and the top of the dome-shaped cover has an exhaust vent. A vertically penetrating ventilation duct is provided in the center of the interior of the dome-shaped cover. A miniature fan is installed at the bottom of the ventilation duct. A temperature sensor, supported by a support rod, is suspended and fixed in the middle of the ventilation duct. A quick-installation interface slot is provided on the back of the main unit. The fixed base has an arc-shaped slide rail adapted to the quick-installation interface slot, and the front end of the arc-shaped slide rail is provided with an elastic buckle.

[0005] Furthermore, several strong magnets are symmetrically installed on the inner walls of both sides of the quick-install interface slot, and a slot for engaging with the elastic buckle is provided on the top of the quick-install interface slot.

[0006] Furthermore, the fixed base is an L-shaped plate, with screw holes at the four corners of the vertical plate and an arc-shaped slide rail on the horizontal plate. A release button is provided on one side wall of the horizontal plate of the fixed base.

[0007] Furthermore, a spring is provided inside the front end of the arc-shaped slide rail, and the other end of the spring is connected to an elastic buckle. A push rod is connected inside the release button, and the push rod is linked with the elastic buckle.

[0008] Furthermore, the main unit of the equipment is divided into three functional compartments arranged vertically by a partition. From top to bottom, these compartments are a dome-shaped outer cover connected to the ventilation duct, a main control compartment that houses the main control board, and a power supply compartment that houses the power module.

[0009] Furthermore, the inner walls of both the main control compartment and the power supply compartment are fitted with a shaped phase change material layer. The power supply compartment has a drawer-type structure and houses the battery. A waterproof rubber ring is provided around the edge of the power supply compartment.

[0010] Furthermore, the dome-shaped outer cover is detachably connected to the main unit of the equipment, and the inner sides of the air inlet and exhaust port are covered with nano-hydrophobic dustproof cotton.

[0011] Furthermore, heat insulation pads are affixed between the vertical plate of the fixed base and the mounting surface, as well as at the mounting base of the main unit of the device.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through its unique "active convection protection chamber" structure, transforms sealed protection into active forced convection cooling. A micro fan periodically draws in the freshest air from the bottom of the chamber, which flows through the temperature sensor probe suspended and fixed in the central air duct before being discharged from the top. The sensor is in direct and continuous contact with the flowing air inside the chamber, and its temperature changes can be captured instantly. The response time is improved by more than 70% compared with traditional sealed equipment, completely eliminating the "thermal hysteresis" phenomenon. In addition, the suspended fixing method avoids thermal conduction interference between the sensor and the internal structure, and measures the true temperature of the airflow core. At the same time, the continuous airflow can blow away the slight dust accumulation on the probe surface, maintaining its optimal sensitivity.

[0013] 2. Through the collaborative design of the "magnetic slide rail quick-install base" and the "modular heat-insulating chamber", the ease of use, maintenance efficiency and long-term reliability of the equipment are greatly improved; the "magnetic slide rail" structure realizes true tool-free "one-stick and one-slide" installation and disassembly, the strong magnet provides initial positioning and attraction, the arc-shaped slide rail ensures precise guidance, and the elastic buckle ensures the firmness after locking.

[0020] Example 1 like Figure 1-4 As shown, this utility model provides a technical solution: a greenhouse temperature monitoring device, including a main unit 1 and a fixed base 2. The main unit 1 is mounted on the fixed base 2, which is fixedly mounted on a wall or column inside the greenhouse. The main unit 1 has a dome-shaped outer cover 101 on its top. The lower part of the side wall of the dome-shaped outer cover 101 has several air inlets 102, and the top of the dome-shaped outer cover 101 has an exhaust port 103. The air inlets 102 on the lower side and the exhaust port 103 on the top together constitute an airflow inlet and outlet. A vertically penetrating ventilation duct 104 is provided in the center of the interior of the dome-shaped outer cover 101. A miniature fan 105 is installed at the bottom of the ventilation duct 104. A temperature sensor 106, supported by a support rod 107, is suspended and fixed in the middle of the ventilation duct 104. When the miniature fan 105 at the bottom is working, it draws in air through the air inlet 102, flows through the temperature sensor 106 suspended and fixed in the middle of the duct, and is discharged from the exhaust port 103, forming active convection to ensure that the sensor is in contact with the freshest air. A quick-installation interface slot 108 is provided on the back of the main unit 1. An arc-shaped slide rail 201 that is adapted to the quick-installation interface slot 108 is provided on the fixed base 2. An elastic buckle 202 is provided at the front end of the arc-shaped slide rail 201.

[0021] Example 2 like Figure 1-4As shown, several strong magnets 109 are symmetrically installed on the inner walls of both sides of the quick-install interface slot 108. A slot for engaging with the elastic buckle 202 is opened on the top of the quick-install interface slot 108. The fixed base 2 is an L-shaped plate. Screw holes 203 are provided at the four corners of the vertical plate of the fixed base 2, and an arc-shaped slide rail 201 is provided on the horizontal plate. A release button 204 is provided on one side wall of the horizontal plate of the fixed base 2. A spring is provided inside the front end of the arc-shaped slide rail 201, and the other end of the spring is connected to the elastic buckle 202. A push rod is connected inside the release button 204, and the push rod is linked with the elastic buckle 202. When the button is pressed, the push rod will push the latch of the elastic buckle 202 inward, causing it to retract and release the lock. Because the arc-shaped slide rail 201 is arc-shaped, the main unit 1 can rotate along this arc within a certain angle (e.g., ±15°) before sliding into the lock to adapt to different installation angles. The main unit 1 is internally divided into three functional compartments arranged vertically by a partition. From top to bottom, these are a dome-shaped outer casing 101 connected to the ventilation duct 104, a main control compartment 110 housing the main control board, and a power supply compartment 111 housing the power module. The dome-shaped outer casing 101 at the top houses the air duct and sensors, and is physically isolated from the main control compartment 110 (where the main control board is installed) in the middle and the power supply compartment 111 (where the battery is installed) at the bottom. The dome-shaped outer casing 101 can be easily unscrewed and opened for cleaning and maintenance. The inner walls of the main control compartment 110 and the power supply compartment 111... All components are covered with a shaped phase change material layer to absorb and stabilize the heat generated by the internal components. The power compartment 111 has a drawer-type structure and houses the battery. A waterproof rubber ring is provided around the edge of the power compartment 111. This drawer-type structure can be opened and closed separately to replace the battery without disassembling the entire device. The dome-shaped outer cover 101 is detachably connected to the device host 1. The inner sides of the air inlet 102 and the exhaust 103 are covered with nano-hydrophobic dustproof cotton. Heat insulation pads are attached between the vertical plate of the fixed base 2 and the mounting surface, as well as at the mounting base of the device host 1.

[0022] The working process of this utility model is as follows: When using a greenhouse temperature monitoring device, first install the fixed base 2 in the selected position inside the greenhouse with screws, then align the quick-release interface slot 108 on the back of the device main unit 1 with the arc-shaped slide rail 201, and the magnet will attract it into place. Slide it down until the elastic buckle 202 locks it in place; after the device is powered on, the micro fan 105 starts intermittently, driving the airflow through the temperature sensor 106 for accurate temperature measurement, and the data is wirelessly transmitted to the monitoring center through the main control board; when it is necessary to replace the battery or clean, press the release button 204 to remove the main unit, which is easy to operate.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
