Description

Technical Field

[0001] The utility model relates to the technical field of diesel engines, in particular to a diesel engine with a quickly detachable cooling water tank. Background Art

[0002] A diesel engine burns diesel fuel to generate energy. Its advantages include high torque and excellent fuel economy. The operating process of a diesel engine shares many similarities with a gasoline engine, with each cycle also undergoing four strokes: intake, compression, power, and exhaust. However, because diesel fuel is more viscous than gasoline and less likely to evaporate, its auto-ignition temperature is lower than gasoline. Therefore, the formation and ignition of the combustible mixture differ from gasoline engines. The main difference is that the mixture in the cylinder of a diesel engine is compression-ignited rather than ignited. When a diesel engine is operating, air enters the cylinder. By the time the air is compressed to its final stage, its temperature can reach 500-700°C and its pressure can reach 40-50 atmospheres. As the primary power source for construction machinery, the cooling water tank is a crucial component of the diesel engine. The water pump on the engine drives the coolant through the cooling water tank and engine, maintaining the engine's operating temperature.

[0003] The cooling water tank on a traditional diesel engine is mainly installed by fixing it with multiple bolts. After working for a long time, scale is easily generated inside the cooling water tank, which easily causes pipe blockage during water circulation in the diesel engine. The cooling water tank needs to be disassembled for cleaning. However, the bolt fixing installation method is not easy to install and disassemble, and the bolts are prone to rust, making it inconvenient to disassemble and disassemble the bolts.

[0004] After searching, a Chinese patent discloses a diesel engine with a quick-detachable cooling water tank (publication number CN222025850U). Although the patent uses a fixed plate, a pull rod and a telescopic spring arranged on the outer wall of the base, and the outer wall of the movable plate contacts the outer wall of the water tank body under the action of the telescopic spring, thereby fixing the water tank body from both sides under the action of the movable plate, the diesel engine will vibrate during operation, which may easily cause the spring to vibrate, causing the clamping state of the movable plate to disappear, and easily causing the risk of the cooling water tank falling off. Therefore, this application provides a diesel engine with a quick-detachable cooling water tank to meet the needs. Utility Model Content

[0033] like Figure 1-6 As shown, the embodiment of the present invention provides a diesel engine with a quick-detachable cooling water tank, comprising a base 1 and a diesel engine 2. The diesel engine 2 is fixedly connected to the upper right side of the base 1. Support bases 3 are fixedly connected to the four corners of the upper left side of the base 1. A cooling water tank 4 is provided on the upper part of the support base 3. Fixing mechanisms 5 are provided on the front and rear sides of the right bottom of the cooling water tank 4.

[0034] The fixing mechanism 5 includes a fixing seat 501, the middle part of each fixing seat 501 is rotatably connected to a pull rod 503, the middle part of each pull rod 503 is rotatably connected to a movable frame 502, the middle part of each movable frame 502 is slidably connected to a movable plate 504, the upper part of each movable plate 504 is provided with a fixing column 505, the upper end of each fixing column 505 is provided with a locking ring 506, and the outer side of each fixing column 505 is provided with a spring 507;

[0036] The outer side of the support seat 3 is fixedly connected with a fixing plate 12, and the fixing seat 501 is fixedly connected to the right end of the corresponding right fixing plate 12. The setting of the fixing plate 12 facilitates the installation of the locking bolt 13 and the fixing seat 501.

[0037] like Figure 3-4 As shown, guide columns 508 are provided on the front and rear sides of the movable plate 504, and guide grooves 509 are provided on the front and rear sides of the movable frame 502. The guide columns 508 are respectively slidably connected to the inner sides of the corresponding guide grooves 509, and limit blocks 510 are provided on the outer sides of the guide columns 508. By sliding the guide columns 508 on the inner sides of the guide grooves 509, the stability and guidance of the movable plate 504 during movement are increased, and the limit blocks 510 are used to prevent the movable plate 504 from falling off.

[0038] like Figure 5-6 As shown, the upper end of the support seat 3 is fixedly connected with a snap-fit ​​block 301, and the middle part of the snap-fit ​​block 301 is provided with a snap-fit ​​groove 302. The four corners of the bottom end of the cooling water tank 4 are provided with positioning grooves 401, and the interior of the positioning grooves 401 is provided with positioning blocks 402. The positioning grooves 401 are snap-fitted and connected with the corresponding snap-fit ​​blocks 301, and the positioning blocks 402 are snap-fitted and connected with the corresponding snap-fit ​​grooves 302.

[0042] like Figure 6 As shown, the outer upper part of the front and rear end fixing plates 12 on the left side are both threadedly connected with locking bolts 13, and the locking bolts 13 are threadedly connected to the left side of the cooling water tank 4. The fixing plate 12 and the cooling water tank 4 are threadedly connected through the locking bolts 13, which increases the convenience of fixing the cooling water tank 4 and prevents the locking hook 513 from being disengaged from the locking ring 506, causing the cooling water tank 4 to fall off.

[0043] like Figure 3 As shown, rubber rings 11 are provided on the outer sides of the front and rear end support seats 3 on the left side, and anti-slip handles 511 are provided on the bottom of the pull rod 503. The anti-slip handles 511 are tightened to the upper part of the support seat 3 through the rubber rings 11 to prevent the vibration generated when the diesel engine 2 is working from causing the anti-slip handles 511 to detach and move. The anti-slip performance during use is increased by the anti-slip handles 511, which increases convenience.

[0044] The technical solution provided by the present utility model is as follows: first, the cooling water tank 4 is placed on the left end of the base 1, and the limiting grooves 403 set at the front and rear ends of the left and right sides of the cooling water tank 4 are aligned with the inner side of the fixing plate 12, and the cooling water tank 4 is placed downward so that the positioning groove 401 and the positioning block 402 are engaged with the locking block 301 and the locking groove 302, and the cooling water tank 4 is engaged with the upper part of the base 1, and then the pull rod 503 set by the fixing mechanism 5 is moved from the outside to the inside so that it rotates in the middle of the fixed seat 501, driving the movable plate 504 to slide on the inner side of the movable frame 502, pushing the spring 507 to contract, so that the locking ring 506 is hung with the locking hook 513, and secondly, the fixing plate 12 is threadedly connected to the cooling water tank 4 by manually twisting the locking bolt 13, and finally the rubber ring 11 is put on the outer side of the support seat 3, and the anti-slip handle 511 is tightened.

[0045] The present invention encompasses any substitutions, modifications, equivalent methods, and solutions that are not within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention above, but those skilled in the art can fully understand the present invention without these detailed descriptions.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
