AI Technical Summary
Existing water supply equipment uses antifreeze devices for water tanks. However, under extreme temperatures, the heat distribution is uneven, causing certain areas of the water tank to freeze easily.
An electric push rod drives a sliding block to slide inside a fixed cylinder. The connecting plate rotates and actuates the plate, which, in conjunction with the heating plate, stirs the water in the tank, ensuring that the water is heated evenly.
In low-temperature environments, the water in the tank remains in a flowing state to prevent freezing, and the heat is evenly distributed, effectively preventing the tank from freezing.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of water tank antifreeze devices, and in particular to an antifreeze device for water tanks in water supply equipment. Background Technology
[0002] In cold environments, water in the tank is prone to freezing. The expansion of the frozen water can damage the tank and affect the normal operation of the water supply equipment. This device may employ various technologies to prevent freezing, such as heating the tank with heating elements, using insulation materials to reduce heat loss, or being equipped with a temperature monitoring system that automatically activates antifreeze measures when the temperature approaches freezing. Therefore, a water supply equipment antifreeze device for the tank is needed.
[0003] Chinese patent provides a water tank antifreeze device for water supply equipment, publication number CN222375559U, which includes a water tank body. Heating pipes are installed through both sides of the water tank body. Fixing kits are fixedly sleeved on the surface of the heating pipes. One side of the fixing kits is bolted to the water tank body. Fixing frames are installed on both sides of the water tank body. A heat-conducting plate is bolted to the inside of the fixing frame through a connecting plate. One side of the heat-conducting plate is attached to the water tank body. A resistance wire is installed on the other side of the heat-conducting plate. A partition plate is welded inside the fixing frame. An energy storage battery is bolted inside the fixing frame.
[0004] The aforementioned antifreeze device has a photovoltaic power supply function, which reduces the cost loss caused by commercial electricity. However, when the antifreeze device is in use, it only uses a heat-conducting plate to heat the water. Under extreme temperatures, the heat is difficult to distribute evenly in the water, causing some areas of the water tank to still freeze easily. Utility Model Content
[0005] The main purpose of this utility model is to provide a water tank antifreeze device for water supply equipment, which can effectively solve the technical problem in the background technology that only heat-conducting plates are used to heat the water, and the heat is difficult to be evenly distributed in the water under extreme temperatures, causing some areas of the water tank to still freeze easily.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A water tank antifreeze device for a water supply equipment includes a water tank, a tank cover on the top of the water tank, two support blocks fixedly installed at the bottom of the water tank, support plates fixedly installed at the bottom of the two support blocks, a fixing plate fixedly installed on the inner wall of the water tank, five actuating plates on the right side of the fixing plate, and four rotating blocks fixedly installed on the front and rear outer walls of the five actuating plates.
[0008] As a further embodiment of this utility model, four connecting strips are provided on the outer walls of the front and rear sides of the five actuating plates, and the outer walls of the connecting strips are rotatably connected to the outer walls of the rotating blocks.
[0009] As a further embodiment of this utility model, one end of the two bottom connecting strips is fixedly connected to the right outer wall of the fixing plate, and one end of the two top connecting strips is fixedly installed with a fixing strip. The front and rear outer walls of the two fixing strips are rotatably connected with connecting plates.
[0010] As a further embodiment of this utility model, two heating plates are fixedly installed on the inner wall of the water tank, and two first support frames are fixedly installed on the outer left side of the water tank, with a fixed cylinder fixedly installed on the top of the two first support frames.
[0011] As a further embodiment of this utility model, the inner walls of both fixed cylinders are slidably connected with sliding blocks, and the bottom of the sliding blocks is fixedly connected to the connecting plate.
[0012] As a further embodiment of this utility model, a second support frame is fixedly installed on the outer wall of each of the two first support frames, a fixing block is fixedly installed on the outer wall of each of the two second support frames, an electric push rod is fixedly installed on the outer wall of each of the two fixing blocks, and the output end of each of the two electric push rods is fixedly connected to one side of the outer wall of the sliding block.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1) The water supply equipment uses a water tank antifreeze device. The output end of the electric push rod can drive the sliding block to move back and forth. The sliding block will slide along the inner wall of the fixed cylinder. When the sliding block slides, it will drive the connecting plate to move together. The connecting plate will cause the fixed bar and the position of the top connecting bar to shift, thereby causing the agitator to continuously move on the inner wall of the water tank, achieving the effect of stirring the water inside the water tank, so that the water inside the water tank is always in a flowing state and is not easy to freeze in cold conditions.
[0015] 2) The water supply equipment uses a water tank antifreeze device. The heating plate can heat the water in the tank. As the agitator plate continuously moves the water in the tank, the water in the tank can be heated more evenly, thereby further increasing the temperature of the water in the tank and effectively preventing the water from freezing in low-temperature environments.
