When animals such as cows, horses, baboons, donkeys, sheep, and pigs eat grass or eat whole crops, foodstuffs obstruct the esophagus and cannot be swallowed. Usually called “grasshoppersâ€; “grass tadpoles†often appear in autumn and winter. . symptom The “grasshopper†livestock often stop eating suddenly, shook his head and neck, mouth drooling, continuously vomiting or swallowing; the eye conjunctiva is dark red, rapid heartbeat, restlessness. If you do not receive timely treatment, it will often cause adverse consequences or even death. prevention Feeding on time to prevent excessive starvation of the livestock; to block and feed the sweet potatoes, radish, etc., chopped and then fed; when the animals eat, do not spurt promptly; be cautious, do not disappear, do not panic feed. Treatment (1) If the part of the animal that is clogged is in the front part of the esophagus, you can use your hand to hold it in the mouth, and then use your hand to pull it out. (2) If the site of the animal's obstruction is in the middle of the esophagus, then 150 ml of vegetable oil may be fed first, and the obstruction may be pushed by hand to the pharynx, and then the obstruction may be removed from the oral cavity. (3) Use a short bridle to catch the left forelimb of the animal, so as to lower the head as far as possible, and then drive the animal up and down the slope to run fast. Repeatedly several times, the obstruction can slide into the stomach and release the danger. (4) Feed the animals with a small amount of vegetable oil first, then use a hard hose to insert into the esophagus through the nostrils, and slowly push the blockage into the stomach. (5) After the foreign body is removed from the throat, use 500 grams of white wine, 150 to 250 grams of kerosene, and 1,000 grams of vinegar, or 50 grams of vegetable oil, and 500 grams of vinegar, and mix and grit once for livestock suffering from rumen blows. . (6) Use mussels, guadi, pepper, and saponin equal parts, a little musk, total research into fine, put into the bamboo tube, blow into the nostrils of the sick animals.

There is no doubt that solar monitoring has brought great convenience to people. It saves a lot of manpower and material resources without having to stick to the post for 24 hours as before. Not to mention that the current surveillance cameras have the function of motion detection. As long as someone enters a certain range, it will automatically alarm and capture the scene. What is the function of the solar monitoring system?

1. Solar panel: The solar panel is an important part of the mobile phone software of the solar power generation system, and also a part of the practical value of the mobile phone software of the solar power generation system. Its function is to convert the professional ability of radioactive substances in natural light into electric energy, or send them to storage batteries, or promote load work.
2. Solar controller: The solar controller is used to control the operation of mobile phone software in all systems, and has the functions of overcharge protection and overcharge maintenance for the battery. In areas with large temperature difference, the qualified controller shall also have the function of temperature compensation. In the mobile phone software of the solar road lamp system, there must be light control switch and time control solar road lamp operation.
3. Battery: generally valve controlled maintenance free lead-acid battery. In the mobile phone software of small and medium-sized systems, in cold weather areas, a solar gel battery needs to be configured, which can be used at low temperatures, with high efficiency and is not vulnerable to major damage. Its function is to store the electric energy of the solar panel when the sun shines, and then release it under certain conditions.
4. Variable frequency power supply: split wave type and sine wave type. In order to provide power for 220VAC electrical products, it is necessary to convert the DC stabilized voltage power supply in the solar power generation system software into AC circuit energy, so DC AC variable frequency power supply is required.
