Greenhouse irrigation device capable of simulating vegetable water loss

Abstract

The invention provides a greenhouse irrigation device capable of simulating vegetable water loss, and relates to the technical field of Internet of things equipment. The device comprises a fixed seat,wherein an electromagnet is fixedly connected to the inner wall of the bottom of the fixed seat; a resistor electrically connected with the electromagnet is fixedly connected to the inner wall of thebottom of the fixed seat; and a negative plate is fixedly connected to the inner wall of the right side of the fixed seat. According to the greenhouse irrigation device capable of simulating vegetable water loss, through the cooperative use of a variable resistance block and an electric heating block, when the device is used, a heat conduction block can conduct the temperature in a greenhouse toa bimetallic plate, so that the bimetallic plate is heated and bent downwards, the bending degree of the bimetallic plate can be adjusted according to the temperature, and as a result, the bimetallicplate points to different positions of the variable resistance block, the heating temperature of the electric heating block is controlled, the evaporation speed of water in a water tank is controlled,the water loss speed of plants at different temperatures is simulated, the speed of simulating the water loss of the plants is achieved, the irrigation efficiency of greenhouse planting is improved,and the yield of greenhouse planting is increased.

Description

technical field [0001] The invention relates to the technical field of Internet of Things equipment, in particular to a greenhouse irrigation device that can simulate the water loss of vegetables. Background technique [0002] The Internet of Things is an information carrier based on the Internet, traditional telecommunication networks, etc. It enables all ordinary physical objects that can be independently addressed to form an interconnected network. The Internet of Things is the "Internet that connects everything" and is an extension of the Internet And the extended network, a huge network formed by combining various information sensing devices with the Internet, realizes the interconnection and intercommunication of people, machines and things at any time and any place. [0003] Based on the rapid development of the Internet of Things, the current greenhouse planting also adopts the Internet of Things technology. The Internet of Things is used to control the irrigation de...

Problems solved by technology

[0003] Based on the rapid development of the Internet of Things, the current greenhouse planting also adopts the Internet of Things technology. The Internet of Things is used to control the irrigation device, and the plants are irrigated regularly and quantitatively to ensure that the plants can have sufficient water. However, when the current irrigation device is in use, it cannot Accurately determine whether plants need water, only mechanical timing and quantitative irrigation, resulting in too much or too little irrigation, or untimely irrigation, affecting the growth of plants and reducing the productivity of Mipeng planting
