This year's heavy rains and greenhouse protection have been done in advance

Reinforce the greenhouse and protect the shed

Walls: The back slope and both sides of the solar greenhouse should be covered with plastic sheet or thatch cloth for sealing.

Membrane: If the tympanic membrane phenomenon occurs during heavy rain, the membrane line should be pressed immediately or part of the (half-rolled) grass thatch should be pressed on the middle of the roof in front of the greenhouse. If the roof curvature in front of the greenhouse is small and the laminating line is not firmly pressed, use bamboo or wooden poles to laminate the film. If the laminating line is blown away by the wind at night, it should be pulled back to the original position in time.

Repair and reinforce the skeleton, for example: tie the three connecting rods of the greenhouse with iron wire

Strengthen the vent to prevent rain

First, protect the face in front of the shed. Be sure to check whether the drainage ditch around the greenhouse is dredged, and clean the drainage ditch in time to prevent rainwater from entering the shed. For sheds without drainage ditches, you must hurry to install them. You can dig a trench with a width of 30 cm and a depth of 40 cm at the front face of the shed, and connect the reservoir in front of the shed to this ditch to prevent the reservoir in front of the shed from being isolated. .

Second, protect the air outlet. Before it rains, close the vents in time to prevent rainwater and mud spots splashed by raindrops from infecting vegetables with pathogens. If in continuous rainy weather, a rain film should be installed at the air outlet of the greenhouse, which can prevent raindrops from falling on the vegetable leaves, and does not hinder the ventilation and cooling of the greenhouse when it rains.

Maintain the back wall to prevent water from collapsing

The slope on the back wall where people can stand is the most prone to water accumulation. Therefore, to avoid water accumulation on the back slope, first use a whole new plastic film to cover the back slope diagonally and fasten it. If you want to reduce costs, you can use the old shed film to cover up to 2 layers to ensure that rainwater cannot penetrate. After using plastic film, the back wall is covered with a layer of non-woven fabric and other sun protection materials, which can effectively prevent rainwater from accumulating and penetrating.

Protection in case of heavy rainfall

At this time, we must pay close attention to the situation in the shed. Once rainwater is found to ingress, take measures to remedy it as soon as possible, raise the water inlet, and pump water to drain water in time.

Protection after heavy rainfall

The straw curtain and thermal insulation quilt must be wrapped twice. After heavy rain, the straw curtain and quilt wrapped in the shed must be carefully inspected, especially the damaged area, must be covered twice to prevent strong winds and rain leakage Go in.

The roller shutter machine should focus on protection. After the support rod is welded, the roller shutter machine of the new greenhouse must be painted with anti-rust paint on the outside of the support rod, and the top of the auxiliary rod must be sealed to prevent rainwater from entering. If the supporting rod of the installed roller blind cannot be sealed at the top, some small holes can be drilled at the bottom of the auxiliary rod so that the incoming rainwater can be removed in time.

Long Range LiDAR Radar

Long distance LiDAR sensor series are particularly easy to communication thanks to their fixed connector, which can be plugged it up and off by yourself. Voltage is wider from 8v before to 36v. Low power consumption feature makes it beceome a very competitive, high performance-price ratio, long range Laser Distance Sensor.

Highlights:

> Measurement frequency: 400 Hz (Max 60m 3000Hz)
> Long range: 200m
> High temperatures: -10~+50℃
> UART output
> Connector design: easy to use
