There are many types of earth sockets, including pop-up earth socket size: 120 x 120 mm, open earth socket size: 146 x 146 x 4 mm and spiral earth socket size: 130mm x 130.
Sliding ground socket size: 120*120mm. Type 120 common modules are based on 1/3 standard, that is, three 1/3 standard modules can be installed on a standard 120mm × 74mm panel mounted vertically. Modules are divided into three types according to their size: 1/3, 2/3 and 1 bit.
Type 118 common modules are based on a 1/2 standard, that is, two standard 1/2 modules can be installed on a standard 118 mm × 74 mm panel mounted horizontally. Modules are divided into two types: 1/2 and 1 bit depending on the size. In actual installation and use, type 120 and 118 modules are gradually becoming more common. A panel can accommodate either three modulesthe standard 1/3, or two 1/2 modules.
Detailed information:
1. Pay attention to waterproofing: Since the wall socket is installed in a relatively high position, it is difficult to get water unless it is used with wet hands or splashed by water. Earthing is different, especially earthing in a humid environment. Once there are water stains on the ground, it is easy to wet the socket and suffer electric shock. Therefore, the ground plug should be chosen with a waterproof cover, otherwise it will not be waterproof.
2. Do not open it with your feet: the socket is installed on the floor. Opening it by hand requires bending or crouching, which is really laborious. Therefore, many friends can directly use their feet to open thee plug cover for convenience. In fact, this approach is very incorrect. One sole is not clean, which can easily cause dust and stains to enter the socket, and the other can easily damage the socket cover.
3. Close the cover after use: After using the grounded plug, remember to put the cover back on the socket. This can produce two effects, one is waterproof and the other is stain resistant.

Ground micro-spraying is an irrigation technology.
Micro sprinkler irrigation is an irrigation method that sprays water at a low rate onto the soil surface through a low-pressure pipe system for irrigation. It is a new irrigation technology gradually formed on the basis of drip irrigation and sprinkler irrigation. During micro-sprinkler irrigation, theWater is ejected from the micro-sprinklers at a high rate, and is crushed into fine water droplets under the action of air resistance and falls on the ground or on the leaves of crops. Since the outlet orifice and flow rate of the micro sprinkler are greater than the flow rate of the emitter and the flow rate of drip irrigation, emitter clogging is significantly reduced. Micro sprinkler irrigation can also spray soluble chemical fertilizers with irrigation water directly onto the soil surface around crop leaves or roots, thereby improving fertilization efficiency and saving usage. chemical fertilizers.
