[0027] like Figure 1 As shown, a fan hydraulic cylinder for automatically cleaning sludge includes: a cylinder body 1, a piston rod 2 arranged in the cylinder body 1, and a cleaning device 3 connected to the piston rod 2 and abutting against the inner wall of the cylinder body 1.

[0028] The sidewall of the cylinder body 1 is also provided with a groove 4 for collecting the oil sludge removed by the cleaning device 3. The hydraulic cylinder also includes a sealing ring 5 sealed to a notch (not shown) in the groove 4. It is understood that the groove 4 communicates with the exterior of the cylinder through the notch. The oil sludge collected in the groove 4 can be cleaned by removing the sealing ring 5.

[0029] In the present invention, by providing a cleaning device 3 connected to the piston rod 2 and abutting the inner wall of the cylinder body 1, sludge adhering to the inner wall of the cylinder body 1 can be removed in real time during the operation of the hydraulic cylinder, greatly improving cleaning efficiency and reducing maintenance time and costs. The automatic sludge cleaning design of the present invention can effectively clean the sludge in the pressure cylinder, extend the service life of the equipment, and maintain its efficient operation.

[0030] Furthermore, the sealing ring 5 promptly removes sludge from the groove 4, preventing blockages or other mechanical failures caused by the sludge. This helps improve the stability and reliability of the entire system. The design of the groove 4 allows for centralized processing of collected sludge, simplifying subsequent cleanup. Furthermore, frequent disassembly of the hydraulic cylinder for internal cleaning is no longer necessary, significantly reducing the workload for maintenance personnel and improving work efficiency.

[0031] In some embodiments, one end of the piston rod 2 abuts against the top wall of the cylinder body 1 , and the other end abuts against the bottom wall of the cylinder body 1 .

[0032] The cleaning device 3 includes a connecting rod 31 connected to the piston rod 2 and a wedge-shaped portion 32 connected to the connecting rod 31 and abutting against the inner wall of the cylinder body 1 . The groove portion 4 is adapted in shape to the wedge-shaped portion 32 .

[0033] In the present invention, by making one end of the piston rod 2 abut against the top wall of the cylinder body 1 and the other end abut against the bottom wall, it is ensured that the piston rod 2 can provide stable support throughout the entire stroke, thereby improving the stability of the equipment operation. The cleaning device 3 includes a connecting rod 31 connected to the piston rod 2 and a wedge-shaped portion 32 connected to the connecting rod 31 and tightly fitting against the inner wall of the cylinder body 1. This design enables the wedge-shaped portion 32 to effectively scrape away oil sludge attached to the inner wall of the cylinder body 1 in the direction of piston movement of the piston rod 2. The design of the wedge-shaped portion 32 helps to better adapt to the shape of the inner wall of the cylinder body 1, ensuring that the oil sludge is completely removed.

[0034] Furthermore, the position and shape of the groove portion 4 match the wedge portion 32, ensuring that the sludge scraped off by the wedge portion 32 can be accurately pushed into the groove portion 4 through the wedge portion 32. This design not only improves the efficiency of sludge collection.

[0035] In some embodiments, along the piston movement direction of the piston rod 2 , the groove portions 4 are provided on two opposite side walls of the cylinder body 1 .

[0036] In the present invention, groove portions 4 are provided on both opposite side walls of the cylinder body 1, so that the sludge scraped off from both sides of the cylinder body 1 can be collected simultaneously during the reciprocating motion of the piston rod 2, which not only improves the efficiency of sludge collection, but also reduces the problem of sludge accumulation or incomplete removal caused by unilateral collection.

[0037] In some embodiments, along the piston movement direction of the piston rod 2, the connecting rod 31 includes two first connecting rods 311 arranged on one side of the piston rod 2, and the two first connecting rods 311 are arranged at an angle to the piston rod 2, wherein one first connecting rod 311 extends toward the top wall of the cylinder body 1, and the other first connecting rod 311 extends toward the bottom wall of the cylinder body 1.

[0038] In the present invention, by arranging two first connecting rods 311 extending toward the top wall and bottom wall of the cylinder body 1 respectively on one side of a piston rod 2, the inner wall of the cylinder body 1 can be scraped simultaneously from the upper and lower directions when the piston rod 2 reciprocates, and the sludge attached to the inner wall of the cylinder body 1 can be effectively removed to achieve all-round cleaning coverage.

[0039] In some embodiments, along the piston movement direction of the piston rod 2, the connecting rod 31 includes two second connecting rods 312 arranged on the other side of the piston rod 2, and the two second connecting rods 312 are arranged at an angle to the piston rod 2, wherein one second connecting rod 312 extends toward the top wall of the cylinder body 1, and the other second connecting rod 312 extends toward the bottom wall of the cylinder body 1.

[0040] In the present invention, two groups of connecting rods are respectively arranged on both sides of the piston rod 2 (each group includes a connecting rod toward the top wall and a connecting rod toward the bottom wall), which can ensure that the cleaning device 3 can be effectively driven to work during the entire piston stroke, so that the upper and lower ends of the inner wall of the cylinder body 1 can be fully cleaned, avoiding the problem of incomplete unilateral or local cleaning.

[0041] Furthermore, by simultaneously installing two first connecting rods 311 and two second connecting rods 312 on both sides of the piston rod 2, bidirectional synchronous scraping of the inner wall of the cylinder body 1 can be achieved in one reciprocating motion. This method not only improves the cleaning efficiency, but also can remove accumulated sludge more quickly, reducing the degradation of equipment performance caused by sludge.

[0042] In some embodiments, the wedge portion 32 includes a first wedge 321 connected to the first connecting rod 311 and a second wedge 322 connected to the second connecting rod 312 .

[0043] In some embodiments, the wedge-shaped portion 32 is made of rubber.

[0044] In some embodiments, the hydraulic cylinder further includes a first rubber ring 6 , which is axially arranged around the cylinder body 1 on the inner wall of the cylinder body 1 , and the first rubber ring 6 is fixedly connected to the two first connecting rods 311 .

[0045] In the present invention, the rubber material has good elasticity and flexibility, so that the first rubber ring 6 can fit tightly against the inner wall of the cylinder body 1, forming an effective barrier for scraping oil sludge. When the piston rod 2 drives the first connecting rod 311 to perform reciprocating motion, the first rubber ring 6 can effectively scrape off the oil sludge and other impurities attached to the inner wall of the cylinder body 1, ensuring a better cleaning effect.

[0046] In some embodiments, the hydraulic cylinder further includes a second rubber ring 7 , which is axially arranged around the cylinder body 1 on the inner wall of the cylinder body 1 , and the second rubber ring 7 is fixedly connected to the two second connecting rods 312 .

[0047] In the present invention, the rubber material has good elasticity and flexibility, so that the second rubber ring 7 can fit tightly against the inner wall of the cylinder body 1, forming an effective barrier for scraping oil sludge. When the piston rod 2 drives the second connecting rod 312 to perform reciprocating motion, the second rubber ring 7 can effectively scrape off the oil sludge and other impurities attached to the inner wall of the cylinder body 1, ensuring a better cleaning effect.

[0048] A specific example provided by the present disclosure includes:

[0049] A cleaning device 3 is mounted on the piston. Specifically, the cleaning device 3 is mounted on the fixed handle of the piston rod 2. Connecting rods are mounted on both sides of the piston rod 2. The first connecting rod 311 and the second connecting rod 312 near the top wall of the cylinder body 1 are welded into a trumpet shape. The first connecting rod 311 and the second connecting rod 312 near the bottom wall of the cylinder body 1 are welded into a trumpet shape. A first wedge 321 is mounted at the end of the first connecting rod 311, and a second wedge 322 is mounted at the end of the second connecting rod 312. The wedges are made of rubber and fit perfectly with the inner wall of the cylinder body 1.

[0050] During the movement, the piston rod 2 moves back and forth through the hydraulic oil supply and return to drive the fan bearing (also called fan shaft 8) to move. During the movement of the bearing, the cleaning device 3 moves with the piston. As the running time becomes longer, the piston stroke of the piston in the cylinder body 1 is regularly opened to the maximum and closed to the minimum to allow the scraped sludge to be collected in the grooves 4 on both sides of the cylinder body 1.

[0051] Grooves 4 are provided on both sides of the cylinder body 1, and sealing rings 5 are packaged in the grooves. The size of the sealing ring 5 is consistent with the outer diameter of the cylinder body 1 and fits perfectly. The wedge-shaped piece pushes the sludge to the groove part 4 at the end. After the fan stops operating, the hydraulic oil is stopped and the sealing ring 5 at the end of the cylinder body 1 is removed to clean the sludge.

[0052] According to a second aspect of the embodiments of the present disclosure, a fan is provided, comprising the above-mentioned fan hydraulic cylinder for automatically cleaning sludge.

[0053] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present disclosure, and the present disclosure is not limited thereto. Those skilled in the art may make various modifications and improvements without departing from the spirit and substance of the present disclosure, and such modifications and improvements are also considered to be within the scope of protection of the present disclosure.
