Abstract
Description
Technical Field
[0001] This utility model relates to the field of antifreeze filling, and more specifically, to an antifreeze replenishment vehicle. Background Technology
[0002] Antifreeze (full name: antifreeze coolant) is an engine coolant with antifreeze function. It is mainly used to prevent the cooling system from freezing in cold environments. It also has functions such as anti-boiling, anti-corrosion, and anti-scaling. It is suitable for the cooling system of internal combustion engine equipment such as automobiles all year round.
[0003] Currently, antifreeze is generally added manually. The general method involves using a large-capacity can or packaged antifreeze product. However, because antifreeze containers are large and inconvenient to move, operators must first use a water pump to draw the antifreeze into a smaller container, then carry it to the equipment for refilling. Furthermore, the equipment lacks a refill pump, requiring operators to carry a water pump, power outlet, two 14mm air hoses, rags, and other tools each time, making the refilling process cumbersome and inefficient.
[0004] Chinese patent CN116161605A discloses an antifreeze filling device, in which a pumping mechanism, under the control of a controller, pumps antifreeze into a delivery pipeline and then injects it into the cooling pipeline. However, this device lacks a return mechanism, and manual filling is still required for storing and filling antifreeze. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0030] Example
[0031] Please refer to Figure 1 This application provides an antifreeze replenishment vehicle, including a frame 1 and a replenishment machine 2 fixed above the frame 1. The bottom surface of the replenishment machine 2 is fastened to a water tank 3 and a replenishment mechanism. The replenishment mechanism includes a replenishment assembly 4 and a return assembly 5 arranged side by side. A control host 6 is mounted between the replenishment assembly 4 and the return assembly 5.
[0032] As a preferred implementation, the frame 1 can be a four-wheel drive all-terrain vehicle chassis, equipped with snow tires or snow chains, to adapt to extreme and complex road conditions such as ice and snow. The bottom of the refill machine 2 is equipped with a fixing frame, which is used to fix the water tank 3 and the refill machine 2 to the bottom of the refill machine 2 with bolts, so as to prevent the water tank 3 or the refill mechanism from being damaged by collision due to shaking during movement.
[0033] Please refer to Figure 2 and Figure 4 Furthermore, the replenishment assembly 4 includes a replenishment pipe 401, a replenishment tank 402, and a replenishment circulation pump 403. One end of the replenishment pipe 401 is connected to the top surface of the replenishment tank 402, and the other end is connected to the replenishment port 8 located on the back of the replenishment machine 2. A water pipe 7 is connected to the bottom surface of the replenishment tank 402, and a one-way valve is connected to the inlet of the water pipe 7. The one-way valve is controlled by the control host 6 to start and stop. The replenishment circulation pump 403 is connected to the bottom of the water pipe 7. Similarly, The return liquid assembly 5 includes a return liquid pipe 501, a return liquid tank 502, and a return liquid circulation pump 503. One end of the return liquid pipe 501 is connected to the top surface of the return liquid tank 502, and the other end is connected to the return liquid port 9 located on the back of the replenishment machine 2 and extends outward. The bottom surface of the return liquid tank 502 is also connected to a water pipe 7, and a one-way valve is connected to the inlet of the water pipe 7. The one-way valve here is also controlled by the control host 6 to start and stop. The return liquid circulation pump 503 is connected to the bottom of the water pipe 7. The control host 6 is fixedly mounted between the replenishment tank 402 and the return liquid tank 502, and controls the start and stop of the replenishment circulation pump 403 and the return liquid circulation pump 503 through circuitry. The replenishment circulation pump 403 and the return liquid circulation pump 503 are connected by the water pipe 7.
[0034] The side panel of the liquid replenishment machine 2 is also equipped with a control panel 16, which is connected to the control host 6. The liquid replenishment machine 2 also has an internal power supply (not shown in the figure) that powers the entire liquid replenishment machine 2. In actual use, the operator first places the end of the return pipe 501 extending from the return port 9 into the antifreeze tank. The return assembly 5 is started through the control panel 16. The one-way valve in the return assembly 5 opens, and the one-way valve in the replenishment assembly 4 closes. The return circulation pump 503 starts working, drawing the antifreeze into the return tank 502. Then, under the action of the return circulation pump 503, the antifreeze flows through the water pipe 7 into the water tank 3 for storage. When replenishment is needed, the replenishment assembly 4 is started through the control panel 16. The one-way valve in the replenishment assembly 4 opens, and the one-way valve in the return assembly 5 closes. Under the action of the replenishment circulation pump 403, the antifreeze is first pumped into the replenishment tank 402 through the water tank 3, and then flows out of the replenishment port 8 through the replenishment pipe 401.
[0035] Please refer to Figure 3 In this embodiment, the replenishment port 8 is also externally connected to a replenishment gun 12. Optionally, the replenishment gun 12 can be an LLY type metering refrigerant gun, which has a compact structure, small size, and light weight. It is equipped with an error adjustment device and an adjustable rated flow function to improve metering accuracy. During use, the operator can monitor the amount of antifreeze being replenished in real time, which can prevent antifreeze overflow to a certain extent. The one-way valve is a pneumatic or electric valve and is connected to the control host 6 for easy control.
[0036] Furthermore, the side of the liquid replenishment machine 2 also has a hanging slot 13 for hanging the liquid replenishment gun 12. When not in use, the liquid replenishment gun 12 can be placed on the hanging slot 13 to effectively prevent antifreeze leakage. When liquid replenishment is needed, the liquid replenishment gun 12 can be removed.
[0037] It should be noted that in this embodiment, the replenishment pipe 401 and the return pipe 501 are adapted to the dimensions of the replenishment port 8 and the return port 9, respectively, and can be disassembled.
[0038] Please refer to Figure 5 Furthermore, the inner wall of the water tank 3 is also provided with an insulation layer 10, and electric heating elements 11 are evenly distributed within the insulation layer 10. After the operator stores the antifreeze in the water tank 3 through a single return cycle, the electric heating elements 11 heat up to room temperature (25°C), ensuring that the temperature inside the water tank 3 remains stable at room temperature. This ensures that the antifreeze can maintain its chemical properties even when the outside temperature is low, and also prevents the water tank 3 from being damaged due to cold compression at low temperatures.
[0039] Optionally, since the main component of antifreeze is ethylene glycol aqueous solution, which is highly corrosive, the insulation layer 10 can be made of stainless steel or high-strength corrosion-resistant engineering plastics, which are materials that can withstand corrosion for a long time.
[0040] Optionally, the replenishment tank 402 and the return tank 502 are made of the same material as the water tank 3. The replenishment tank 402 and the return tank 502 are also equipped with an insulation layer 10 and an electric heating element 11 to keep the temperature of the antifreeze consistent throughout the entire return-storage-replenishment process.
[0041] Please refer to Figure 6 Similarly, to prevent the housings, pipes, valves, etc., in the replenishment assembly 4 and return assembly 5 from freezing in extreme low-temperature environments, heating pipes 14 are installed at the connection ports of the replenishment circulation pump 403, the return circulation pump 503, and the water pipe 7, as well as on the inner walls of the replenishment pipe 401 and the return pipe 501. This ensures that the antifreeze flowing through the replenishment assembly 4 and the return assembly 5 remains at room temperature, and also prevents the antifreeze from being affected by freezing at pipe openings and other connections. Optionally, a layer of rubber-plastic sponge can be wrapped around the water pipe 7 to further prevent damage caused by compression at low temperatures.
[0042] Optionally, to prevent antifreeze leakage during use, overflow controllers can be installed at the filler port 8 and the return port. This is a common existing technology and will not be described in detail here.
[0043] Furthermore, a level gauge is installed inside the water tank 3, and a level observation window 15 is also provided on the front of the replenishment machine 2. The level gauge can be a magnetic float level gauge with strong corrosion resistance, or other types of level gauges, used to monitor in real time whether the antifreeze in the water tank 3 has been replenished to the specified level. In addition, during replenishment, the operator can also observe through the level observation window 15 on the front of the replenishment machine 2 whether the antifreeze has entered the water tank 3 smoothly.
[0044] In summary, the embodiments of this utility model provide an antifreeze replenishment vehicle that can adapt to various complex road conditions. By setting up a connected replenishment assembly 4 and a return assembly 5, antifreeze can be stored in the water tank 3 first, and when replenishment is needed, it can be directly discharged through the replenishment gun 12. The operation is simple and convenient.
[0045] By providing an insulation layer 10 on the inner wall of the water tank 3, and by providing heating pipes 14 on the inner walls of the replenishment pipe 401 and the drain pipe, the condensation of antifreeze can be effectively prevented when the temperature is too low.
