Abstract
Description
Technical Field
[0001] This invention relates to the field of gasoline generator technology, specifically a water-cooled gasoline generator. Background Technology
[0002] Gasoline generators typically consist of a starter assembly and an engine assembly. The starter assembly includes a stator support, stator core, and rotor core. These components are usually classified as low-temperature components, with operating temperatures typically maintained between 40 and 60°C. The engine assembly consists of components such as the engine block and cooling fan, which are classified as high-temperature components, with operating temperatures typically maintained between 80 and 110°C (this is the operating condition under normal temperature conditions). In special circumstances, the operating temperature in the high-temperature zone can reach 150 to 300°C, which undoubtedly increases the probability of thermal failure.
[0003] Currently used gasoline generators mostly have a fixed and compact internal structure. This means that in high-temperature environments, the operating temperature of the high-temperature zone will be directly transferred to the starter unit, resulting in severe heat buildup between the two. At this time, the machine's built-in water-cooling + air-cooling design is difficult to solve the heat buildup problem, leading to a high probability of thermal failure. Summary of the Invention
[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.
[0005] Therefore, the technical solution adopted in this invention is as follows: A water-cooled gasoline generator includes a generator assembly, a cooling mechanism, a temperature reduction mechanism, and a pitch control mechanism. The generator assembly includes an integrated starter assembly, a splined bushing fixedly connected to the output end of the integrated starter assembly, a splined shaft slidingly passing through the top of the splined bushing, and an engine assembly fixedly connected to the top of the splined shaft. The cooling mechanism includes a pitch control platform fixedly sleeved to the bottom of the engine assembly, a cotton pad interference-fitted around the outside of the engine assembly, a hollow sleeve fixedly sleeved to the outside of the cotton pad, a sleeve suspended above the top of the cotton pad and fixedly connected to the inner wall of the hollow sleeve, multiple drippers passing through the bottom of the sleeve, a water supply pipe connected and communicating with the sleeve, a water tank fixedly connected to the top of the pitch control platform, and a connection between the water supply pipe and the water tank. The system includes a micro pump, two hydraulic cylinders fixed between the adjusting platform and the hollow jacket, a cooling mechanism comprising multiple air ducts penetrating the inner wall of the hollow jacket, an air inlet channel penetrating the outer wall of the hollow jacket, and three arc-shaped openings on the adjusting platform, and an adjusting mechanism comprising two baffles fixed to both sides of the integrated starter assembly, a support frame fixedly sleeved on the outer side of the two baffles, two threaded rods screwed to both sides of the support frame, a rectangular block movably sleeved on the inner end of the threaded rod, a crossbar I embedded in the top of the baffle, two transmission rods I movably connected between the rectangular block and the crossbar I, two crossbars II embedded in both sides of the adjusting platform, and two transmission rods II movably connected between the rectangular block and the crossbars II.
[0006] By adopting the above technical solution, in a high-temperature environment, the threaded rod rotates inward, and then the two rectangular blocks approach each other. The transmission rod one and transmission rod two cooperate to control the adjustment platform and the engine assembly to approach the starter assembly. Then, the micro pump is started, and air is injected into the air intake channel. The micro pump pumps cold water in the water tank to the water supply pipe and sleeve. The cold water is distributed through multiple drips to wet the cotton swab. Then, the moving end of the hydraulic cylinder reciprocates, indirectly causing the cotton swab to repeatedly wipe the surface of the engine assembly. At this time, the air flowing out from the hollow jacket and air duct achieves dual cooling of air and water. Then, the downward air gradually dissipates its temperature before contacting the starter assembly, thereby achieving a gentle cooling of the starter assembly and reducing the thermal failure rate.
[0007] In a preferred embodiment, the present invention may be further configured such that the water supply pipe passes through a hollow jacket and extends into the interior of the water tank, and the water supply pipe is configured as a flexible hose.
[0008] In a preferred embodiment, the present invention can be further configured such that two hydraulic cylinders are located on the front and rear sides of the engine assembly, respectively, and the two hydraulic cylinders are connected in series.
[0009] In a preferred embodiment, the present invention can be further configured such that: the air inlet channel is located at the bottom of the water pipe body, and both the air duct and the air inlet channel are connected to the interior of the hollow jacket.
[0010] In a preferred embodiment, the present invention can be further configured such that both ends of the threaded rod are T-shaped, and both the threaded rod and the rectangular block are made of alloy material.
[0011] In a preferred embodiment, the present invention can be further configured such that: both the first transmission rod and the second transmission rod have openings at their outer ends, and both the first transmission rod and the second transmission rod are made of shape memory metal material.
[0012] In a preferred embodiment, the present invention can be further configured such that a retaining ring is fixedly connected to the top of the adjusting platform, and the engine assembly and the three arc openings are all located inside the retaining ring.
[0013] In a preferred embodiment, the present invention can be further configured such that a digital temperature sensor is fixedly connected to the front side of the adjusting platform, and the digital temperature sensor is electrically connected to an external power supply.
[0014] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. In this invention, under high temperature conditions, the threaded rod is rotated inward, and then the two rectangular blocks approach each other. The transmission rod one and the transmission rod two cooperate to control the adjustment platform and the engine assembly to approach the starter assembly. Then, the micro pump is started and air is injected into the air intake channel. The micro pump pumps cold water in the water tank to the water supply pipe and the sleeve. The cold water is distributed through multiple drips to wet the cotton swab. Then, the moving end of the hydraulic cylinder reciprocates, indirectly causing the cotton swab to repeatedly wipe the surface of the engine assembly. At this time, the air flowing out from the hollow jacket and the air duct achieves dual cooling of air and water. Then, the downward air gradually dissipates its temperature before contacting the starter assembly, thereby giving the starter assembly a gentle cooling effect and reducing the thermal failure rate.
[0015] 2. In this invention, under low-temperature conditions, the threaded rod is rotated outward to move the rectangular block to its maximum limit position. The rectangular block pulls the transmission rod one and the transmission rod two outward. Under the action of this mechanism, the adjusting table moves downward, causing the engine assembly mounted on it to descend until it approaches the integrated starter assembly. At this time, air is injected into the air intake channel, and the airflow is sent out through the air duct. The high-temperature heat generated after the engine assembly starts is carried by the airflow and transferred to the integrated starter assembly, effectively preheating it and thus quickly entering a stable power generation working state.
[0016] 3. In this invention, during the air-cooling operation, the hot air moving down along the outer wall of the engine assembly is guided to the arc position by the baffle ring when it comes into contact with the top of the pitch control table, so that the hot air can pass through multiple arcs and ensure the air-cooling effect on the engine assembly.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0020] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.
[0021] The following describes, with reference to the accompanying drawings, some embodiments of a water-cooled gasoline generator provided by the present invention.
[0022] Example 1: Combining Figures 1-7As shown, the present invention provides a water-cooled gasoline generator, including a generator mechanism 100, a cooling mechanism 200, a temperature reduction mechanism 300, and a pitch adjustment mechanism 400. The generator mechanism 100 includes an integrated starter assembly 110, a splined bushing 120 fixedly connected to the output end of the integrated starter assembly 110, a splined shaft 130 slidably passing through the top end of the splined bushing 120, and an engine assembly 140 fixedly connected to the top end of the splined shaft 130. The cooling mechanism 200 includes an adjusting platform 210 fixedly sleeved to the bottom of the engine assembly 140, a cotton swab 220 interference-fitted to the outside of the engine assembly 140, a hollow sleeve 230 fixedly sleeved to the outside of the cotton swab 220, a sleeve 240 suspended above the cotton swab 220 and fixedly connected to the inner wall of the hollow sleeve 230, a plurality of drippers 250 penetrating the bottom of the sleeve 240, a water supply pipe 260 connected and communicating with the sleeve 240, a water tank 270 fixedly connected to the top of the adjusting platform 210, a micro pump 280 fixedly connected between the water supply pipe 260 and the water tank 270, and two hydraulic cylinders 290 fixedly connected between the adjusting platform 210 and the hollow sleeve 230. The cooling mechanism 300 includes multiple air ducts 310 penetrating the inner wall of the hollow jacket 230, an air inlet channel 320 penetrating the outer wall of the hollow jacket 230, and three arc-shaped openings 330 on the adjusting table 210. The distance adjustment mechanism 400 includes two baffles 410 fixedly connected to both sides of the integrated starter assembly 110, a support frame 420 fixedly sleeved on the outside of the two baffles 410, two threaded rods 430 screwed to both sides of the support frame 420, a rectangular block 440 movably sleeved on the inner end of the threaded rod 430, a crossbar 450 embedded in the top of the baffles 410, two transmission rods 460 movably connected between the rectangular block 440 and the crossbar 450, two crossbars 470 embedded in both sides of the distance adjustment platform 210, and two transmission rods 480 movably connected between the rectangular block 440 and the crossbar 470.
[0023] Furthermore, the water supply pipe 260 passes through the hollow jacket 230 and extends into the water tank 270. The water supply pipe 260 is configured as a flexible hose. Using a flexible hose to make the water supply pipe 260 ensures that the water supply pipe 260 can be flexibly deformed when the hollow jacket 230 is raised or lowered, so that the water supply operation can be carried out stably.
[0024] Furthermore, two hydraulic cylinders 290 are located on the front and rear sides of the engine assembly 140, respectively. The two hydraulic cylinders 290 are connected in series. The connection relationship of the hydraulic cylinders 290 can make the hollow jacket 230 rise and fall smoothly, providing conditions for repeated water cooling of the engine assembly 140.
[0025] Furthermore, the air inlet channel 320 is located at the bottom of the water pipe 260, and both the air duct 310 and the air inlet channel 320 are connected to the interior of the hollow jacket 230. This structural design ensures that the air cooling operation can be carried out smoothly.
[0026] Furthermore, both ends of the threaded rod 430 are T-shaped, and both the threaded rod 430 and the rectangular block 440 are made of alloy material. Using alloy material to make the threaded rod 430 and the rectangular block 440 can improve the structural stability of this device.
[0027] Furthermore, a digital temperature sensor is fixedly connected to the front side of the adjustment platform 210. The digital temperature sensor is electrically connected to an external power supply. The digital temperature sensor facilitates external operators to understand the ambient temperature on site and provides temperature data for adjusting the distance between the engine assembly 140 and the starter unit assembly 110.
[0028] Example 2: Combination Figure 1 , 6 and Figure 7 As shown, based on Embodiment 1, both the first transmission rod 460 and the second transmission rod 480 have an opening 500 at their outer ends. Both the first transmission rod 460 and the second transmission rod 480 are made of shape memory metal material. The opening 500 facilitates the removal of the first transmission rod 460 and the second transmission rod 480, making the device easy to maintain.
[0029] Example 3: Combination Figure 1 As shown, in the above embodiment, a retaining ring is fixed to the top of the adjusting platform 210, and the engine assembly 140 and the three arc openings 330 are all located inside the retaining ring. The retaining ring can guide the air flowing out of the air duct 310 to the position of the arc opening 330 when it acts on the adjusting platform 210, so that the air cooling operation can act on the integrated starter assembly 110.
[0030] Working principle and usage process of this invention: Preheating process in low-temperature environments: The operator rotates the threaded rod 430 outward, causing the rectangular block 440 to move outward to its maximum limit position. The rectangular block 440 pulls the transmission rod 460 and the transmission rod 480 outward. Under the action of this mechanism, the adjusting table 210 moves downward, causing the engine assembly 140 mounted on it to descend until it approaches the starter assembly 110. At this time, air is injected into the air inlet channel 320, and the airflow is sent out through the air duct 310. The high temperature heat generated after the engine assembly 140 starts is carried by the airflow and transferred to the starter assembly 110, effectively preheating it and thus quickly entering a stable power generation working state.
[0031] Heat dissipation process under high temperature environment: In a high-temperature environment, the operator rotates the threaded rod 430 inward. Based on the same transmission principle, the adjusting table 210 drives the engine assembly 140 to rise, moving it away from the starter assembly 110. During this process, the spline bushing 120 and the spline shaft 130 achieve a sliding fit, ensuring a stable power transmission connection between the engine assembly 140 and the starter assembly 110. The distance between the engine assembly 140 and the starter assembly 110 prevents the high temperature generated by the engine assembly 140 from being directly transferred to the starter assembly 110. Then, the micro pump 280 is started, and air is injected into the air intake channel 320. The micro pump 280 draws cold water from the water tank 270, sends it into the sleeve 240 through the water pipe 260, and then distributes it evenly through multiple drippers 250, immersing the cotton swab 220 in the cold water to make it fully wet. Then, the movable end of the hydraulic cylinder 290 begins to move up and down, driving the hollow jacket 230 and the cotton swab 220 to move synchronously. The wet cotton swab 220 repeatedly wipes the surface of the engine assembly 140, using the evaporation of water to absorb heat and dissipate heat, thus achieving the water cooling effect. At the same time, the airflow duct 310, which is injected from the outside, blows on the engine assembly 140 to form air cooling. The combined effect of water cooling and air cooling produces a synergistic heat dissipation effect that is greater than the sum of its parts. The hot air then flows downward along the surface of the engine assembly 140 and continues to act on the starter assembly 110 after passing through multiple arcs 330. The hot air gradually dissipates its temperature in the gap between the engine assembly 140 and the starter assembly 110, thereby allowing the starter assembly 110 to be gently cooled and preventing overheating.
[0032] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
