Problems solved by technology
[0002] At present, the oil cylinders for rubber dam steel gates are exposed outside. If there is water downstream, a lot of fine sediment will be deposited in the small grooves outside the oil cylinders, which will wear the seals for a long time, and may also damage the The piston rod is scratched, which requires frequent maintenance and replacement, which not only increases the cost, but also affects the operation of the gate

specific Embodiment approach
[0009] The specific embodiment: the specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:
Embodiment
[0010] Embodiment: a kind of anti-sediment oil cylinder for rubber dam steel gate (see figure 1 ), which includes a cylinder body 4, the cylinder body 4 is connected to the piston head 1 through the piston rod 3, and an elastic sand-proof sleeve 2 is arranged between the piston rod 3 outside the piston rod 3 and the piston head 1, and the elastic sand-proof sleeve 2 is in the shape of a truncated cone. Its lower end edge is provided with dust-proof skirt 5, and dust-proof skirt 5 is connected with cylinder body 4 by screw. The elastic anti-sand cover 2 is made of elastic materials such as rubber, and the height of the elastic anti-sand cover 2 is 1-3cm (best 2cm) larger than the distance between the upper end of the cylinder body 4 and the lower end of the piston head 1.

The invention discloses an anti-silt oil cylinder for a rubber dam steel gate. The anti-silt oil cylinder comprises a cylinder body (4), and the cylinder body (4) is connected with a piston head (1) through a piston rod (3). The anti-silt oil cylinder is characterized in that an elastic anti-silt sleeve (2) outside the piston rod (3) is arranged between the piston rod (3) and the piston head (1), and the height of the elastic anti-silt sleeve (2) is 1 cm -3 cm larger than the distance between the upper end of the cylinder body (4) and the lower end of the piston head (1). The anti-silt oil cylinder is simple in structure, practical and long in service life, cost is reduced, and stable operation of the steel gate is guaranteed.
Description
Technical field: [0001] The invention relates to an anti-sediment oil cylinder for a steel gate of a rubber dam, which belongs to the technical field of water conservancy barrages. Background technique: [0002] At present, the oil cylinders for rubber dam steel gates are exposed outside. If there is water downstream, a lot of fine sediment will be deposited in the small grooves outside the oil cylinders, which will wear the seals for a long time, and may also damage the seals. The piston rod is scratched, which requires frequent maintenance and replacement, which not only increases the cost, but also affects the operation of the gate. Invention content: [0003] The object of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a kind of anti-sediment oil cylinder for rubber dam steel gate with simple and practical structure, long service life, low cost and stable operation of the steel gate. [0004] The purpose of the pres...
