Description

Technical Field

[0001] The present invention relates to the technical field of fixing water purification equipment, especially the fixing technology of water vending machines, and particularly relates to a fixing device and method for water purification equipment. Background Art

[0002] As a convenient drinking water supply device, especially water vending machines, water purification equipment is widely used in places such as communities, schools, and factories. It can provide people with directly drinkable water or barreled water that has been purified and meets health standards, meeting people's need to access safe drinking water at any time. However, water vending machines are usually large in size and heavy in weight, and contain precise water treatment components and electrical systems inside. During daily use, they are easily affected by external factors, such as vibrations caused by the flow of people and passing vehicles, strong wind impacts brought by bad weather, the expansion of frozen water in winter causing damage to water pipes, and tilting that may occur due to uneven ground. These not only affect the normal operation of the water vending machine, shorten its service life, but may even pose safety hazards. Therefore, in order to ensure the stable, safe, and efficient operation of the water vending machine, a fixing device for water purification equipment is indispensable. It can firmly fix the water vending machine, resist various external interferences, and ensure that it continuously provides high-quality drinking water services to the public.

[0003] When using traditional water purification equipment fixing devices, first, according to the installation site conditions of the water vending machine, after clearing debris, the basic components of the device (such as a metal frame) are transported to the predetermined position, leveled using a spirit level, holes are drilled in the ground through anchor bolts or expansion bolts, and the basic components are fixed to ensure their stability and no displacement in both the horizontal and vertical directions. Then, according to the specific dimensions of the water vending machine, the positions of the fixing clamps (such as L-shaped metal clamps on the side and frame-type clamps on the top) are adjusted to precisely fit the sides and top of the water vending machine, and then the clamps are tightly connected to the water vending machine and the basic components with bolts to firmly hold the water vending machine and prevent it from shaking or tipping over. After the fixing operation, the firmness of each connection part needs to be repeatedly checked to ensure the safe operation of the water vending machine.

[0004] There are usually two methods for installing water vending machines in the current market. One is to directly use the bottom support legs of the water vending machine. Since the area around and under the water vending machine is often a humid environment, the bottom support legs often rust, resulting in unstable fixing of the water vending machine. And in winter, due to the four-sided exposure of the support legs to the wind, if cold water freezes and expands, the bottom pipes may be damaged. When the pipes are damaged and leak water, it may come into contact with the circuit, ultimately forming a safety hazard. The other is to use bricks or concrete to build a base for the water vending machine. Although it plays a role in safety and stability, it is time-consuming to build, and the labor cost is too high. Moreover, it will be difficult to move the water vending machine again after the base is formed. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a fixing device and method for a water purification device, which solves the problem that the water dispenser is prone to rust during installation, resulting in unstable fixing of the water dispenser and damage to the water dispenser.
