The invention relates to the technical field of ship construction, in particular to a sea chest grating which comprises coamings, lug plates, connecting bolts, grating plates, hinge seats, bent plates, connecting cross rods, supporting plates, limiting grooves, cleaning mechanisms, anti-falling mechanisms and locking mechanisms. According to the novel sea chest grating, the grating plate is in a slotted hole opening form, the size of the openings needs to be designed according to the size of a pump body impeller runner, it is guaranteed that the size of sundries or particles is smaller than the size of the impeller runner, the hinge is installed close to the middle position, and the two supporting legs and a ship body structure are welded and fixed. The balance function of a balancing weight can be replaced by the self weight of the grille, in addition, after the grille is closed, a straight pin is inserted into a bolt opening for locking, underwater operation is facilitated, the grille is low in cost and easy to manufacture, and the problem that the grille is strenuous to open and close underwater is solved through redesign of the grille form.
本发明涉及船舶建造技术领域,尤其为一种海底门格栅,包括围板、耳板、连接螺栓、格栅板、铰接座、弯板、连接横杆、支撑板、限位槽、清理机构、防脱机构和锁止机构;本新型海底门格栅,格栅板采用长圆孔开孔形式,开孔大小需根据泵体叶轮流道尺寸进行设计,保证杂物或颗粒物尺寸小于叶轮流道尺寸,铰链采用靠中位置安装,用两支撑腿与船体结构焊接固定,使格栅可以通过自身重量替代配重块的平衡功能,另外,在格栅关闭后采用直型销插入螺栓开孔中进行锁紧,便于水下进行操作,本设计发明成本低廉,制作简单,通过对格栅形式的重新设计解决了在水下开关格栅费力的问题。
