The utility model discloses a sample storage device for water quality environment detection, which comprises a water quality sampler and a counterweight base, and the bottom of the water quality sampler is fixedly connected with the top of the counterweight base. Through cooperative use of a fixing device, a fixing clamping plate, a limiting groove and a spring, the problems that an existing water quality sampler belongs to one of sample storage devices for water quality environment detection, the water quality sampler is put into water during use, the water quality sampler is taken out when the water quality sampler is full, water quality conditions of water bodies with different depths possibly have significant differences, and the water quality environment is affected are solved. However, a water quality sampler is light in weight and cannot accurately move to a specific depth of the water area, and the sampler which cannot adjust the weight can only collect a water sample on a surface layer or at a certain fixed depth and cannot obtain complete vertical water quality information. However, an existing water quality sampler for water quality environment detection is not provided with a component for adjusting the weight according to water areas with different depths.

This utility model discloses a grinding device for automotive workpiece surface treatment, belonging to the technical field of grinding devices for automotive workpiece surface treatment. It includes a metal grinding machine, a mounting disc, a mounting shell, a grinding disc, and a mounting sleeve. The bottom of the metal grinding machine is fixedly connected to the top of the mounting disc, and the top of the mounting shell is fixedly connected to the bottom of the mounting disc. This utility model, by setting up an installation mechanism, solves the problem that surface grinding of automotive workpieces is a core step in ensuring the quality of subsequent processes and the performance of the final product. The grinding device for automotive workpiece surface treatment is used to grind the surface of automotive parts. Grinding discs in grinding machines are usually installed using bolts. High-speed vibration of the grinding machine can cause the bolts to loosen, easily leading to the grinding disc shifting or even flying off during operation. Furthermore, disassembling the bolts after installation is difficult, requiring repeated rotation with tools such as handles, which is time-consuming.

This utility model discloses an automatic water supply device for pig farms, relating to the technical field of automatic water supply devices for pig farms. It includes a drinking support, a water level controller, an inlet pipe, a drain pipe, a drinking basin, a filter basin, two docking shells, and two movable handles. The drain pipe is located at the bottom of the water level controller, and the inlet pipe is fixedly connected to the front of the water level controller. This utility model, by incorporating a docking device, solves the problem that automatic water supply devices, including components such as a water level controller, inlet pipe, drain pipe, and drinking basin, typically have pig feed and water in the same area. When pigs finish eating and drink, food residue falls into the drinking basin, which can accumulate over time and cause water quality deterioration, affecting the pigs' health. Drinking basins usually require long-term use and regular cleaning; however, frequent cleaning wastes water resources. Existing automatic water supply devices lack a component for easily removing food residue from the drinking basin.

The utility model discloses an auxiliary cooperation structure of automobile magnetic switch relates to auxiliary cooperation structure of automobile magnetic switch technical field, including starter, magnetic switch, installation ring and installation round shell, the bottom of starter is fixedly connected with the top of installation round shell, the surface of installation round shell is movably connected with the inner chamber of installation ring, the bottom of installation ring is fixedly connected with the surface of starter. The utility model discloses through setting installation device, has solved the auxiliary structure of automobile magnetic switch is the cooperation structure of assisting magnetic switch normal operation, and magnetic switch mounting structure belongs to one kind of auxiliary structure, usually, the bottom of magnetic switch is provided with mounting bracket, and when installing, mounting bracket is positioned in the starter of car through bolt, but the bolt is susceptible to starter vibration and produces loosening, and long -term high -frequency vibration also can reduce the pretightening force between the thread, after long -term use, the bolt will not be able to install the magnetic switch stably.
