The invention discloses an Internet of Things water meter shell which comprises an upper protective shell and a lower protective shell. The upper protective shell and the lower protective shell are matched with each other, a clamping mechanism and a locking mechanism are arranged between the upper protective shell and the lower protective shell, and mounting cavities matched with an Internet of Things water meter are formed in the lower surface of the upper protective shell and the upper surface of the lower protective shell. Arc-shaped clamping plates matched with the water pipes are arranged at the left ends and the right ends of the upper protective shell and the lower protective shell correspondingly, and heat preservation plates are bonded to the inner front walls and the inner rear walls of the upper protective shell and the lower protective shell correspondingly. According to the Internet of Things water meter shell, in the using process, the heat preservation plate can achieve the purpose of heat preservation of an Internet of Things water meter, the internal temperature of the shell is monitored through a temperature sensor, and when the temperature is lower than the set temperature, a controller enables an electric heating plate to be started to slowly heat the interior of the shell; and therefore, the condition that the Internet of Things water meter is frozen can be avoided, and the aim of protecting the Internet of Things water meter is achieved.

The invention is applicable to the technical field of fruit cultivation and provides a fruit cultivating method with breathable cold-proof cloth. The method comprises (1) when the temperature falls into a certain temperature range, arranging a plurality of support rods by taking a fruit tree as the center and around the outside of the fruit tree at a certain radius so as to position the fruit treeinside the plurality of support rods; (2) covering the fruit tree and the support rods with the breathable cold-proof cloth of a certain area and ensuring contact between the breathable cold-proof cloth and the ground; (3) tying ropes to the edge of the breathable cold-proof cloth, tensioning the rope and fixing the rope to a certain position with a fixing member so that the breathable cold-proofcloth can be in a convex shape to cover the fruit tree. The fruit cultivating method with the breathable cold-proof cloth can avoid cold damage, frozen damage and frost damage to fruits, improve thebearing rate of the fruit tree in the coming year and effectively reduce the shrinkage rate and the drop rate of the fruits as well as consumption of sugar in the fruits. Meanwhile, the fruit cultivating method with the breathable cold-proof cloth is convenient and simple to operate, and simply by supporting the breathable cold-proof cloth with the support rods, saves erection of fruit supports and is low in labor costs.
