Description

Technical Field

[0001] This utility model relates to the field of water pump technology, and in particular to a cooling mechanism for a gasoline engine water pump. Background Technology

[0002] A gasoline engine water pump is a liquid transport device powered by a gasoline internal combustion engine. It converts piston motion into crankshaft rotation power through a four-stroke cycle, which then drives the pump impeller to transport liquid using centrifugal force. Its applications are wide-ranging: in agriculture, it's used for irrigation and drainage; in industry, it provides cooling water, construction site drainage, and mine pumping, and can handle liquids containing silt; in emergency rescue and disaster relief, it serves as drainage and temporary fire-fighting water sources; in outdoor operations, it can pump domestic water; and in municipal sanitation, it can be used for sewage transfer. Compared to electric water pumps, gasoline engine water pumps do not require an external power source, offering significant advantages in remote, power-deprived, or mobile environments. They also have a wide operating range. In recent years, with advancements in environmental protection technology, some models have adopted low-emission gasoline engines that meet the National IV emission standard, maintaining strong power while reducing exhaust pollution, further expanding the equipment's application boundaries and market space.

[0003] However, traditional gasoline engine water pumps suffer from poor heat dissipation due to environmental factors. In high-temperature operating environments, such as outdoor farmland irrigation in summer or high-temperature industrial sites, the surrounding air temperature is already high, making it difficult to effectively remove engine heat through air cooling, which can cause the engine temperature to rise rapidly. In poorly ventilated confined spaces, such as underground drainage or enclosed basement operations, poor air circulation prevents heat from dissipating in time, resulting in a significant decrease in heat dissipation efficiency. At the same time, when using the pump in rainy weather, it is necessary to build a waterproof shed or cover it with a rainproof cloth. If not protected, rainwater may seep into the engine ignition system, causing short circuits and preventing starting. Water entering the carburetor can cause abnormal fuel mixture ratios, resulting in engine stalling. Therefore, a cooling mechanism for a gasoline engine water pump is proposed to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cooling mechanism for a gasoline engine water pump.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cooling mechanism for a gasoline engine water pump includes a mounting frame and two sets of handles, each set of handles being located on one side of the mounting frame. Multiple connecting frames are fixedly connected to the upper end of each mounting frame, and a water tank is fixedly connected to the upper end of each of the multiple connecting frames. A protective plate is fixedly connected to the outer periphery of the water tank.

[0007] The cooling component is fixedly installed at the bottom of the water tank and is used to cool the gasoline engine water pump during operation.

[0008] As a further description of the above technical solution:

[0009] The cooling component includes multiple water spray pipes, each fixedly connected to the bottom of a water tank. Multiple water spray holes are provided at the bottom of the water tank. Atomizing plates are fixedly connected inside each of the multiple water spray pipes. A water outlet pipe is fixedly connected to one side of the water tank. A water outlet switch is fixedly installed at the bottom of the water outlet pipe, and a water outlet is fixedly connected to the bottom of the water outlet pipe. An inlet pipe is fixedly connected to the adjacent side of the water outlet pipe. An inlet switch is fixedly connected to the bottom of the inlet pipe, and a water inlet is fixedly connected to the bottom of the inlet pipe.

[0010] As a further description of the above technical solution:

[0011] A motor is fixedly connected to the opposite side of the mounting bracket, and an oil tank is fixedly connected to the opposite side of the mounting bracket.

[0012] As a further description of the above technical solution:

[0013] Two sets of rollers are rotatably connected to one side of the bottom of the mounting frame, and two sets of support frames are fixedly connected to the side of the mounting frame away from the two sets of rollers.

[0014] As a further description of the above technical solution:

[0015] The water spray holes are equidistantly located at the bottom of the water tank, and the water spray pipes are equidistantly located at the bottom of the water tank.

[0016] As a further description of the above technical solution:

[0017] The bottom end of the water outlet pipe is connected to the inner wall of the water outlet, and the bottom end of the water inlet pipe is connected to the inner wall of the water inlet.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the atomizing plate inside the water spray pipe disperses water into water mist. Compared with traditional air cooling, it has a large latent heat of vaporization, which can remove heat from the engine surface. In high-temperature environments, it avoids power reduction and component wear caused by overheating. Continuous water circulation prevents water temperature from rising. The motor-driven water circulation system ensures that the temperature of the heat dissipation medium is lower than the engine temperature.

[0020] 2. In this utility model, the protective plate adopts double-layer heat insulation material, which can reduce the surface temperature of the water tank in summer and reduce the heat radiation of direct sunlight on the equipment. In rainy weather, the arc design of the protective plate guides rainwater to drip along the edge, avoiding seepage into the critical parts of the engine. Traditional equipment requires time to build a rain shelter for rainy weather operation. This design can achieve heat dissipation and protection at the same time through the integration of the protective plate and the atomization system, reducing manual intervention and reducing the risk of equipment damage due to operational negligence.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-5This utility model provides an embodiment of a cooling mechanism for a gasoline engine water pump, including a mounting frame 1 and two sets of handles 2, each set located on one side of the mounting frame 1. Multiple connecting brackets 16 are fixedly connected to the upper end of each mounting frame 1, and a water tank 5 is fixedly connected to the upper end of each connecting bracket 16. A protective plate 6 is fixedly connected to the outer periphery of the water tank 5, which can be used for sunshade in summer and rain protection in rainy weather. A cooling component is fixedly installed at the bottom of the water tank 5 for cooling the gasoline engine water pump during operation. The cooling component includes multiple water spray pipes 8, each fixedly... Connected to the bottom of water tank 5, multiple spray holes 7 and 8 are fixed to the inner wall of water tank 7. Water is supplied to the inside of water tank 8 through the 7. Atomizing plates 9 are fixedly connected inside the multiple spray pipes 8. Water is dispersed in a mist through the 9, which improves the overall cooling effect of water tank 1 and prevents damage to the inside of water tank 1 due to excessive water flow. A water outlet pipe 10 is fixedly connected to one side of water tank 5. A water outlet switch 11 is fixedly installed at the bottom of water outlet pipe 10. A water outlet 15 is fixedly connected to the bottom of water outlet pipe 10. A water inlet pipe 12 is fixedly connected to the adjacent side of water outlet pipe 10. The bottom of water inlet pipe 12 is fixedly connected to... A water inlet switch 13 is connected to the water inlet pipe 12, and a water inlet 14 is fixedly connected to the bottom end of the water inlet pipe 12. A motor 17 is fixedly connected to the opposite side of the mounting bracket 1. When 17 is started, water flows out through the suction points 14 and 15. When cooling is required, 13 is opened, and a large amount of water will rush into the interior of 12 due to the water suction principle. At the same time, 11 is opened, and the rushing water will drain out along 10 with the water outlet of 15. During this period, some of the flowing water will flow out along 8 and play a role in heat dissipation for the whole of 1 through atomization of 9. An oil tank 18 is fixedly connected to the opposite side of the mounting bracket 1, and two sets of rollers are rotatably connected to one side of the bottom end of the mounting bracket 1. 3. Two sets of support frames 4 are fixedly connected to the side of the mounting frame 1 away from the two sets of rollers 3. Slightly lift and push 2 to make 4 away from the ground. At this time, it can be moved by rotating 3. When it is moved to a suitable position, 4 can be placed in contact with the ground to be placed stably. The water spray holes 7 are equally spaced at the bottom of the water tank 5, and the water spray pipes 8 are equally spaced at the bottom of the water tank 5 to make the mist area wider and the heat dissipation more uniform. The bottom end of the water outlet pipe 10 is connected to the inner wall of the water outlet 15, and the bottom end of the water inlet pipe 12 is connected to the inner wall of the water inlet 14. Due to the connection of 10 and 15, 12 and 14, the water inside 5 is constantly replaced, which improves the heat dissipation effect.

[0030] Working principle: The mounting frame 1 serves as the core load-bearing component. The handles 2 on both sides facilitate the operator's movement of the equipment. The rollers 3 at the bottom cooperate with the support frame 4. The operator can slightly lift the handles 2 to lift the support frame 4 off the ground, and then move it flexibly via the rollers 3. After reaching the designated position, the support frame 4 is lowered to contact the ground, ensuring the equipment is placed stably. The water tank 5 on top is fixed to the top of the mounting frame 1 via the connecting frame 16. The outer protective plate 6 blocks direct sunlight in summer and rainwater in rainy weather, protecting the core components of the equipment and preventing environmental factors from affecting the equipment performance.

[0031] The bottom of the water tank 5 is equipped with multiple spray pipes 8, which are connected to the inside of the water tank through spray holes 7. Atomizing plates 9 are installed inside the spray pipes 8. When the cooling function is activated, water in the water tank flows into the spray pipes 8 through the spray holes 7 and is dispersed into a fine mist by the atomizing plates 9. Compared to traditional water flow cooling, the vaporization of the mist has a higher heat absorption efficiency, quickly removing heat from the surface of the mounting bracket 1 and water pump components. It also prevents excessive water flow from seeping into the equipment, causing short circuits or corrosion of mechanical parts. The motor 17 is the power source for water circulation. When cooling is required, the operator simultaneously opens the water inlet switch 13 and the water outlet switch 11. After the motor 17 starts, it generates suction to draw external water into the water tank 5 through the water inlet 14 and water inlet pipe 12. The water in the water tank 5 is discharged through the water outlet pipe 10 and water outlet 15. During this cycle, some water flows out through the spray pipe 8 and is atomized, cooling the mounting frame 1 and the water pump as a whole. The continuous water circulation keeps the water in the water tank 5 constantly updated, preventing the heat dissipation efficiency from decreasing due to rising water temperature. This ensures that the equipment can maintain a stable heat dissipation effect even when running for a long time. The spray pipe 8 and spray holes 7 are evenly distributed at the bottom of the water tank 5, ensuring that the atomization area covers the key heat-generating parts of the equipment, making the heat dissipation more uniform. The water outlet pipe 10 is tightly connected to the water outlet 15, and the water inlet pipe 12 is tightly connected to the water inlet 14, ensuring a smooth water circulation path and reducing water flow resistance. The combination design of the roller 3 and the support frame 4 takes into account both the ease of movement and the stability of operation of the equipment. It is suitable for diverse outdoor scenarios such as farmland irrigation and emergency drainage, ensuring its continuous and stable operation in complex environments.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
