According to a report by the British "Daily Mail" on the 22nd, Professor Jenny Mordecou of the University of Aberdeen found that mosquitoes prefer certain odors and some odors are more annoying. She thus developed an insect repellent that conceals the scent that mosquitoes like, so that mosquitoes no longer regard people who are within the potency of insect repellents as a "blood meal."
Professor Mordieu developed a device similar to an air purifier, releasing a few drops of insect repellent every few minutes. She envisages that people can use the device in a tent or mobile home, or they can drip insect repellent on clothes or badges.
Modiyu said that this is a brand-new method of insect repellent. It is not necessary for mosquitoes to come into contact with human skin and they can be driven away. “This insect repellent can keep mosquitoes far and even prevent mosquitoes from entering. room".
Modiyou plans to test the effectiveness of this insect repellent in a field sporting event in September this year.
Construction Hoist Electrical Parts
Some common electrical parts used in construction hoists include:
1. Control panel: This is the main electrical component that allows the operator to control the movement of the hoist. It typically includes switches, buttons, and indicators for various functions such as raising, lowering, and stopping the hoist.
2. Motor: The motor is responsible for providing the power to operate the hoist. It converts electrical energy into mechanical energy to lift and lower the load.
3. Limit switches: These switches are used to set the upper and lower limits of the hoist's movement. They help prevent the hoist from overtraveling and causing damage.
4. Emergency stop button: This is a safety feature that immediately stops the hoist's operation in case of an emergency or malfunction.
5. Overload protection: This is a safety mechanism that automatically stops the hoist if it exceeds its maximum load capacity. It helps prevent accidents and equipment damage.
6. Electrical cables and wiring: These components connect the various electrical parts of the hoist, allowing for the transmission of power and control signals.
7. Circuit breakers and fuses: These protective devices are used to prevent electrical overload and short circuits. They automatically cut off the power supply in case of excessive current flow.
8. Voltage regulator: This device ensures a stable and consistent supply of electrical power to the hoist, protecting it from voltage fluctuations.
9. Sensors: Various sensors, such as proximity sensors or limit switches, are used to detect the position, speed, or presence of objects in the hoist's path. They provide feedback to the control system and help ensure safe and efficient operation.
10. Wiring connectors and terminals: These components are used to connect and secure the electrical wires in the hoist, ensuring reliable and safe connections.
The specific electrical parts used in a Construction Hoist may vary depending on the manufacturer and model. It is always recommended to refer to the hoist's user manual or consult with a professional for accurate information.
