Description

1 TARIFF A LIQUID FILLING APPARATUS The technical field to which the invention relates: The invention enables pressurized filling of a liquid reservoir located on board an aircraft. providing, perfectly matching the reservoir opening and during filling 5 It relates to a liquid filling apparatus that prevents leakage. State of the art: Used to protect operational unmanned aerial vehicles (UAVs) from ice. Liquids are filled manually using a funnel. Pressurized filling. Because it cannot be done this way, refilling an aircraft with fluid takes approximately 5 hours. 10 This manual process, in addition to being a waste of time, causes the liquid to spill onto the operator and Because there is a possibility of it spilling onto the aircraft, it is also a matter of occupational health and safety. This carries a risk. Error or incorrect action by the personnel performing the liquid filling process. There is also a possibility that the equipment may fall into the aircraft's cargo hold as a result of its use. Additionally... The filling devices must have a leak-proof design and fit together perfectly. 15 It is necessary. Furthermore, hydraulics can maintain high pressure even when it is possible to achieve it during liquid filling. Problems with piston loosening in hydraulic transmission systems operating under pressure. It is located there. The nut, which is used to prevent the piston from loosening, is separate from the piston. Because they are included as a component, these two are sufficiently robust in 20 The problem of lack of interconnectedness arises. This situation leads to high pressure and In high-speed fluid transfer operations, the piston or nut may loosen, and this... This can result in a loss of connection power. Connection Unexpected loosening of these components can lead to fluid leaks. The South Korean-made 25 with registration number “KR102057922B1” is in the known state of the art. The invention in question concerns the connection structure of the piston and piston nut. by improving the piston and piston nut to prevent them from loosening. By implementing an integrated structure for the piston nut, we can solve the above problems. It is designed with an improved joint structure between the piston and a piston nut. 2 A hydraulic cylinder device consists of a rod, a piston, and a piston nut. A piston and a piston nut are integrated, thus forming the piston and piston nut. A structure has been developed that prevents the nut from loosening. United States number “US7318327B2” in known state of the art. The invention, which is the subject of the application originating from [origin], is a small-scale liquid oxygen liquefaction device. 5 The device aims to increase safety, efficiency, and costs in liquid oxygen production. The devices and methods developed for lowering the liquid are described. In one application, the liquid a liquid oxygen tank is placed between the cryocooler and the dewar to control oxygen escape. A barrier is added. A boiling tube connected to the dewara prevents the dewara from tipping over. It allows the expanding gas to escape while enabling the liquid to settle safely in the tube. 10 It recognizes a tipping trigger switch that cuts off the power when the device is tipped over. United States number “US8915268B2” in the known state of the art. The invention that is the subject of the application originating from [origin] is a liquefied gas storage / delivery system. and describes the method involving a liquefied gas storage system. Liquefied gas storage systems include the supply of liquefied gases such as liquid oxygen (LOX). It includes a structure containing a suitable storage container. The structure's outer surface is rotatable. A turntable is provided. The most important feature of a portable liquid storage / delivery device. an interface shaped to fit the shape of at least part of the turntable It is provided in or on a portable liquid storage / delivery device. A connector is located on the interface that connects to a corresponding connector. Two 20 connector, insertion of portable liquid storage / delivery device into interface and rotating It is joined by rotating the table. The current state of the technology involves liquid filling devices. However, UAVs are aerial. A fully leak-proof seal for the vehicle's de-icing system fluid filling adapter. Liquid 25, which has this feature and ensures a perfect fit with the male-female structure of the tank flanges. There are some missing filling devices. In conclusion, due to the negative aspects described above and the current solutions, the subject matter... Due to its shortcomings, an improvement in the relevant technical field is necessary. It has been made. 3 The purpose of the invention: The main purpose of the invention is to connect the UAV's ice protection fluid to the tank filling nozzle and the liquid. by aligning the filling apparatus perfectly and fitting together in a form-compatible manner. The sealing process ensures a leak-proof finish. Another objective of the invention is to reduce the liquid used for ice protection in UAVs to 5. for filling by being able to perform pressurized filling without any leakage. The goal is to save time. Another purpose of the invention is the leak-proof clamping mechanism located on the liquid filling apparatus. Its mechanism is to eliminate risks to occupational health and safety. Another aim of the invention is to develop a fool-proof liquid filling apparatus. Even personnel who have no knowledge of the operation can make mistakes. its purpose is to prevent him from doing it. Another purpose of the invention is to separate the parts of the apparatus by tightening them with a leak-proof bolt. This eliminates the possibility of the aircraft falling into the cargo hold due to operator error.
