如图 1、 图 2所示， 本发明的一种船用避震器， 该避震器包括外套筒 1及用于封闭外 套筒 1顶部及底部的顶板 2及底板 3， 所述外套筒 1内部空腔的中部位置设置有浮球 4， 该浮球 4将外套筒 1的内部空腔分隔成上下两个腔室 11/12， 所述浮球 4的上表面与顶板 2间设置有上弹性件 5， 所述浮球 4的底面与底板 3间也设置有下弹性件 6。 另外， 为了有 效地减少较大风浪对船的冲击， 所述外套筒 1的下部腔室 12内设置有液压油 7， 所述液压 油 7的液位线大概位于下部腔室 12的一半高度位置， 而且所述浮球 4通常选用中心设置 有中心孔 41的金属实心体， 其外形为圆柱形。  As shown in FIG. 1 and FIG. 2, a marine shock absorber comprising an outer sleeve 1 and a top plate 2 and a bottom plate 3 for closing the top and bottom of the outer sleeve 1, the outer casing The middle portion of the inner cavity of the cylinder 1 is provided with a float ball 4 which divides the inner cavity of the outer sleeve 1 into two upper and lower chambers 11/12, between the upper surface of the floating ball 4 and the top plate 2. An upper elastic member 5 is disposed, and a lower elastic member 6 is also disposed between the bottom surface of the floating ball 4 and the bottom plate 3. In addition, in order to effectively reduce the impact of a large wind wave on the ship, the lower chamber 12 of the outer sleeve 1 is provided with hydraulic oil 7, and the liquid line of the hydraulic oil 7 is located approximately half of the height of the lower chamber 12. The position, and the float 4 is generally selected from a solid metal body centered with a central hole 41, which is cylindrical in shape.
在本发明中， 所述上弹性件 5及下弹性件 6均选用压缩性能较好的压缩弹簧； 通常， 浮球 4上表面与顶板 2底部间设置有一条压缩弹簧， 所述浮球 4底面与底板 3间设置有两 条直径不等的内外圈压缩弹簧 61、 62。 另外， 为了将该内外圈压缩弹簧 61、 62紧密的放 置于浮球 4底面与底板 3间， 所述底板 3上设有将压缩弹簧的一端固定在底板 3上的固定 板 8。如图 3及图 4所示， 所述浮球 4底部边缘位置设置有用于容纳外圈压缩弹簧 61顶端 的凹位 42， 所述浮球 4底部的中间位置还设置有用于容纳内圈压缩弹簧 62的凹槽 43。  In the present invention, the upper elastic member 5 and the lower elastic member 6 are each selected as a compression spring having a better compression performance; generally, a compression spring is disposed between the upper surface of the floating ball 4 and the bottom of the top plate 2, and the bottom surface of the floating ball 4 Two inner and outer ring compression springs 61, 62 having different diameters are disposed between the bottom plate 3. Further, in order to closely place the inner and outer ring compression springs 61, 62 between the bottom surface of the float 4 and the bottom plate 3, the bottom plate 3 is provided with a fixing plate 8 for fixing one end of the compression spring to the bottom plate 3. As shown in FIG. 3 and FIG. 4, the bottom edge position of the floating ball 4 is provided with a recess 42 for accommodating the top end of the outer ring compression spring 61, and the middle position of the bottom of the float ball 4 is further provided with a compression spring for accommodating the inner ring. The groove 43 of 62.
与上述相同的是， 所述浮球 4的顶部边缘也设置有用于套设压缩弹簧底部的凹台 44， 这样就能将压缩弹簧稳定地设置于顶板 2底部及浮球 4的表面之间。  Similarly to the above, the top edge of the float ball 4 is also provided with a recess 44 for arranging the bottom of the compression spring, so that the compression spring can be stably disposed between the bottom of the top plate 2 and the surface of the float 4.
另外， 为了使得浮球 4将外套筒 1分成的上下两个腔室 11、 12间有较好的密封性能， 所述浮球 4的外表面设置有密封胶圈槽 45， 该密封胶圈槽 45上设有用于密封的密封胶圈 9。  In addition, in order to make the floating ball 4 have better sealing performance between the upper and lower chambers 11 and 12, the outer surface of the floating ball 4 is provided with a sealing rubber ring groove 45, the sealing rubber ring A sealing rubber ring 9 for sealing is provided on the groove 45.
本发明的船用避震器是安装于船体内，通常对于一般的小型快艇，如图 5及图 6所示， 在对应于船头及船尾侧船体中轴线位置处， 共设置有三个避震器 10， 而且， 为了更好地平 衡船身的稳定性能， 置于船头位置的避震器 10 的总体重量大致是置于船尾位置的每个避 震器重量的两倍。当船在快速行驶时，如果又碰到较大的风浪，船头位置就会被抬起升高， 船尾会下降， 这样， 整个船体极不稳定， 但是安装了避震器 10后， 当遇较大风浪时， 避 震器的外套筒 1的下部压缩弹簧在撞击力的作用下会压缩， 上部的压缩弹簧伸长， 该上下 部的压缩弹簧在回复力的作用下， 即可使得上部的压缩弹簧压缩， 下部的两圈压缩弹簧伸 长， 由于下部压缩弹簧的回复力大于上部压缩弹簧的回复力， 浮球下沉， 即可使得向上抬 升的船头向下被拉回； 同理， 下沉的船尾也会在该处所设的避震器的作用下将船尾抬起， 即可保证整个船身有较好的稳定性能。 除此以外， 由于下部的腔室内设置有液压油， 在较 大风浪冲击时， 下部腔室的液压油通过中心孔后会流入上部腔室， 该液压油不仅起到较好 的润滑作用， 而且由于液压油对浮球本身的浮力， 使得浮球在下沉时也能保持较好的平衡 稳定性能， 从而使得整个船体能平稳的行驶， 稳定性能好； 另外， 该液压油还能起到缓冲 外界较大的冲击力对压缩弹簧的损伤， 以保证压缩弹簧有较长的使用寿命。 The marine shock absorber of the present invention is installed in a hull, and is generally used for a small small speedboat as shown in FIGS. 5 and 6. At the central axis position corresponding to the bow and stern side, a total of three shock absorbers 10 are provided, and in order to better balance the stability of the hull, the overall weight of the shock absorber 10 placed at the bow position is approximately It is twice the weight of each shock absorber placed at the stern position. When the ship is driving fast, if it encounters a large wind and wave, the position of the bow will be raised and the stern will fall. Thus, the entire hull is extremely unstable, but after installing the shock absorber 10, When the wind is large, the lower compression spring of the outer sleeve 1 of the shock absorber compresses under the action of the impact force, and the upper compression spring is extended. The upper and lower compression springs can make the upper part under the action of the restoring force. The compression spring is compressed, and the lower two compression springs are extended. Since the restoring force of the lower compression spring is greater than the restoring force of the upper compression spring, the floating ball sinks, so that the upwardly raised bow is pulled back downward; The sinking stern will also lift the stern under the action of the shock absorber provided by the stern to ensure better stability of the entire hull. In addition, since the lower chamber is provided with hydraulic oil, the hydraulic oil of the lower chamber flows into the upper chamber through the center hole when the large wind wave is impacted, and the hydraulic oil not only performs a good lubrication function, but also Due to the buoyancy of the hydraulic oil on the float ball, the float ball can maintain a good balance stability performance when sinking, so that the entire hull can run smoothly and the stability is good; in addition, the hydraulic oil can also buffer the outside world. The impact of the large impact force on the compression spring ensures a long service life of the compression spring.
本发明并不局限于上述实施方式， 例如： 作为上弹性件的压缩弹簧的数量不仅仅为一 条， 可以为两条或更多， 与此相同的， 下弹性件的压缩弹簧数目也可以为大于两条， 但是 通常为了有较好的避震性能， 作为下弹性件的压缩弹簧的数量应该大于上弹性件的压缩弹 簧的数量， 诸如此类， 凡是对本发明的各种改动或变型不脱离本发明的精神和范围， 倘若 这些改动和变型属于本发明的权利要求和等同技术范围之内， 则本发明也意味着包含这些 改动和变型。  The present invention is not limited to the above embodiment, for example: the number of compression springs as the upper elastic member is not only one, but may be two or more, and the number of compression springs of the lower elastic member may be larger than this. Two, but usually for better suspension performance, the number of compression springs as the lower elastic members should be greater than the number of compression springs of the upper elastic members, and so on, various modifications or variations of the present invention are not departing from the invention. The present invention is also intended to cover such modifications and variations as the scope of the appended claims and the scope of the invention.
