Description

Technical Field

[0001] This utility model belongs to the field of vehicle auxiliary equipment technology, specifically relating to a winter tire water sprayer for trucks with heating function. Background Technology

[0002] When a truck is going downhill for a long distance or braking frequently, the brake drum and tires will generate a lot of heat due to friction. If the heat is not dissipated in time, it can easily lead to safety accidents such as brake failure and tire blowout. To this end, many trucks are equipped with a water spray system, which sprays cooling water onto the brake drum and tires to achieve rapid cooling and ensure driving safety.

[0003] Currently, common water spray systems typically consist of a water tank, water pump, piping, and nozzles. They are simple in structure, low in cost, and suitable for vehicle use in most climates. However, in northern my country and high-altitude cold regions, where winter temperatures often drop below -20°C, existing water spray systems suffer from the following prominent problems: 1. The water tank and pipes are prone to freezing, and the system cannot work properly. Traditional water sprinklers use water as a cooling medium. In low-temperature environments, the water in the water tank, pipes and nozzles is prone to freezing, which can cause the system to be blocked or even cracked. It cannot complete the normal spraying operation, loses the cooling function, and seriously affects driving safety. 2. Generally, a fully open and fully closed solenoid valve is used for water spraying. Long-distance trucks need to frequently travel between the north and south. When in the south, a large amount of water is needed to cool them down, but when passing through northern roads, the temperature is low and a large amount of water spraying is not needed. At the same time, a large amount of water spraying will cause ice accumulation on the road surface, affecting traffic safety. 3. The exhaust manifold heating method has defects. Attempts to heat the water tank by drawing exhaust gas from the engine exhaust pipe have significant shortcomings. Increased exhaust back pressure and the manifold's diversion of exhaust gas can lead to increased back pressure in the exhaust system, affecting engine exhaust efficiency and reducing power output. Exhaust interference is exacerbated; the manifold structure may disrupt the normal flow of exhaust pulses in each cylinder, especially at high speeds, easily causing inter-cylinder exhaust interference and affecting engine combustion efficiency. Directly entering the water tank from the high-temperature exhaust pipe can rapidly heat the water, even causing it to boil. If the water tank lacks a pressure-bearing structure or a safety valve, it may explode due to excessive pressure. When the water boils, bubbles adhering to the exhaust pipe surface significantly reduce heat transfer efficiency, affecting heating effect and even causing localized overheating, posing a serious safety hazard. Utility Model Content

[0004] To address the problems of icing in low-temperature tire spraying systems and design flaws in heating devices, this invention provides a winter tire spraying system for trucks with heating functionality. The system includes a water storage tank, a jacket, an antifreeze circulation pump, an antifreeze expansion tank, an antifreeze circulation heating system, and a spraying system. The jacket is coaxially mounted on the engine exhaust pipe. The jacket, antifreeze circulation pump, antifreeze expansion tank, and water tank are connected via an antifreeze circulation heating system. The antifreeze circulation heating system includes a first antifreeze circulation pipe, a second antifreeze circulation pipe, a third antifreeze circulation pipe, a fourth antifreeze circulation pipe, and an antifreeze heating pipe. The antifreeze heating pipe is installed inside the water tank, with both ends extending out of the water tank. The outlet of the jacket is connected to the inlet of the antifreeze circulation pump via the first antifreeze circulation pipe. The outlet of the antifreeze circulation pump is connected to the inlet of the antifreeze expansion tank via the second antifreeze circulation pipe. The outlet of the antifreeze expansion tank is connected to one end of the antifreeze heating pipe via the third antifreeze circulation pipe. The other end of the antifreeze heating pipe is connected to the inlet of the jacket via the fourth antifreeze circulation pipe. The spray system is connected to the water tank.

[0005] Furthermore, the bottom of the water storage tank is connected to an extension pipe, and the end of the extension pipe is equipped with a drain head. The third antifreeze circulation pipe and the fourth antifreeze circulation pipe pass through the drain head, and the antifreeze heating pipe is extended and arranged inside the extension pipe and connected to the third antifreeze circulation pipe and the fourth antifreeze circulation pipe.

[0006] Furthermore, the spraying system is a multi-nozzle branch pipe, which is connected to the drain head, and a dial regulating valve is provided on the multi-nozzle branch pipe.

[0007] Furthermore, the antifreeze circulation pump is a 24V DC magnetically driven gear pump.

[0008] Furthermore, the water storage tank is arranged on the frame and is equipped with a compressed air injection port, a water storage tank injection port and a water storage tank discharge port. The outer wall is covered with an insulation layer, and the antifreeze heating pipe is fitted with an anti-bend steel spring.

[0009] Furthermore, the outer walls of the first antifreeze circulation pipe, the second antifreeze circulation pipe, the third antifreeze circulation pipe, and the fourth antifreeze circulation pipe are covered with an insulation layer.

[0010] Furthermore, the extension tube is a rubber-insulated steel wire tube. Beneficial effects

[0011] 1. Suitable for high-altitude and long-distance applications: It adopts a closed-loop antifreeze circulation system, so there is no residual water in the pipeline after the machine stops. This completely solves the problem of water pump cracking and jamming due to freezing in environments with a temperature of -20°C. The water sprayer can start reliably at a temperature of -20°C.

[0012] 2. High heat exchange efficiency and rapid heating: The jacket fully wraps around the exhaust pipe, resulting in good heat exchange effect; the extension tube with small volume prioritizes heating, resulting in rapid heating, and the ice inside the extension tube melts in a short time after startup.

[0013] 3. Heat preservation and energy saving: The water storage tank is covered with an insulation layer, and the pipeline can be equipped with an insulation layer. The water temperature can still be maintained for a period of time after the flame is turned off, and it can be used directly after a short-term shutdown and restart.

[0014] 4. Adjustable: The dial adjustment valve allows drivers to adjust the water spray volume during long-distance north-south transportation based on their experience, ensuring sufficient cooling without compromising safety. Attached Figure Description

Detailed Implementation

[0017] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] like Figure 1 As shown, a truck winter tire water sprayer with heating function includes a water storage tank 5, a jacket 2, an antifreeze circulation pump 3, an antifreeze expansion tank 4, an antifreeze circulation heating system, and a spraying system. The jacket 2 is coaxially mounted on the engine exhaust pipe 1. The jacket 2, antifreeze circulation pump 3, antifreeze expansion tank 4, and water tank 5 are connected through an antifreeze circulation heating system. The antifreeze circulation heating system includes a first antifreeze circulation pipe 14, a second antifreeze circulation pipe 10, a third antifreeze circulation pipe 15, a fourth antifreeze circulation pipe 16, and an antifreeze heating pipe 7. The antifreeze heating pipe 7 is installed inside the water tank 5, with both ends extending out of the water tank 5. The outlet of the jacket 2 is connected to the inlet of the antifreeze circulation pump 3 through the first antifreeze circulation pipe 14. The outlet of the antifreeze circulation pump 3 is connected to the inlet of the antifreeze expansion tank 4 through the second antifreeze circulation pipe 10. The outlet of the antifreeze expansion tank 4 is connected to one end of the antifreeze heating pipe 7 through the third antifreeze circulation pipe 15. The other end of the antifreeze heating pipe 7 is connected to the inlet of the jacket through the fourth antifreeze circulation pipe 16. The spray system is connected to the water tank 5.

[0019] The bottom of the water tank 5 is connected to an extension pipe 17, and the end of the extension pipe 17 is equipped with a drain head 18. The third antifreeze circulation pipe 15 and the fourth antifreeze circulation pipe 16 pass through the drain head 18. The antifreeze heating pipe 7 is extended and arranged inside the extension pipe 17 and connected to the third antifreeze circulation pipe 15 and the fourth antifreeze circulation pipe 16. This is to transport the water in the water tank 5 at the front of the vehicle to the wheels. At the same time, when the vehicle is first started, the water tank 5 has a large capacity, and the ice in it can be quickly melted through the extension pipe 17 with a smaller volume, so as to speed up the spraying of water.

[0020] The extension pipe 17 is a rubber-steel wire hose, and the spray system is a multi-nozzle branch pipe 9. The multi-nozzle branch pipe 9 is connected to the drain head 18. The multi-nozzle branch pipe is equipped with a dial adjustment valve 8. The multi-nozzle branch pipe 9 is located above the wheel. The multiple nozzles can increase the coverage area of ​​the water spray while reducing the amount of water sprayed. In conjunction with the dial adjustment valve 8, the flow rate can be reasonably adjusted according to the driver's experience.

[0021] The antifreeze circulation pump is a 24V DC magnetic drive gear pump, and the antifreeze expansion tank is made of PP material.

[0022] The water tank 5 is mounted on the vehicle frame and is equipped with a compressed air injection port 11, a water tank injection port 12, and a water tank discharge port 13. The inner liner is made of SUS304 material, and the outer wall is covered with 25 mm aerogel felt and aluminum foil reflective layer. The antifreeze heating pipe 7 is fitted with an anti-bending steel spring 6 to prevent the antifreeze heating pipe 7 from bending inside the water tank 5 and from being damaged by vehicle vibration.

[0023] The outer walls of the first antifreeze circulation pipe 14, the second antifreeze circulation pipe 10, the third antifreeze circulation pipe 15, and the fourth antifreeze circulation pipe 16 are covered with rock wool.

[0024] Working principle: This invention indirectly transfers the waste heat from engine exhaust to the water tank 5 through a closed-loop antifreeze circulation system. After the vehicle starts, the jacket 2 absorbs the heat from the engine exhaust pipe 1. The antifreeze circulation pump 3 drives the low-temperature antifreeze to flow through the jacket and heat the antifreeze. The high-temperature antifreeze enters the antifreeze heating pipe 7 in the water tank 5 after passing through the antifreeze expansion tank 4. The water in the tank is heated efficiently through heat conduction through the pipe wall. The extension pipe 17 at the bottom of the tank adopts a small volume design, which can complete local rapid heating in a very short time, melt residual ice, and quickly establish spraying capability. The melted water flows through the drain head 18 and the multi-nozzle branch pipe 9 under pressure and sprays the tires. The driver can precisely control the spray flow rate according to the actual working conditions through the dial adjustment valve 8 to achieve on-demand cooling of the brake drum and tires. After the system stops, the antifreeze overcomes the freezing risk of traditional water circulation systems.
