An anti-disengagement throwing hook device suitable for an offshore pneumatic line throwing device and manual throwing is suitable for smooth recovery of underwater equipment under severe sea conditions and comprises a hook head, an anti-disengagement blocking piece, a guide extension rod and a hook rod. A rope tying hole is formed in the top of the hook rod; the three hook heads are welded to the top of the hook rod. The opening of the hook head is provided with a spring anti-falling baffle plate; the guide extension rod is welded at the end part of the hook head, and the guide extension rod is obliquely arranged outwards. The anti-falling hook throwing device is matched with a pneumatic line throwing device or is directly and manually thrown, so that a floating rope can be smoothly hooked at a long distance and a short distance under severe sea conditions, and underwater equipment connected with the rope can be recycled. The actual use effect shows that the anti-falling hook throwing device is simple in working principle and convenient to operate and use, the anti-falling blocking piece can be replaced, the anti-falling hook throwing device can be used repeatedly immediately, and the recovery efficiency and success rate of underwater equipment can be greatly improved.

    一种适用于海上气动抛绳器和手动抛投的防脱抛钩装置,适用于水下设备在恶劣海况条件下顺利回收,包括钩头、防脱挡片、导向延长杆、钩杆;所述钩杆的顶部设有系绳孔;所述钩头设有三个,焊接于钩杆的顶部;钩头开口处安装有弹簧防脱挡片;钩头的端部焊接有所述导向延长杆,且所述导向延长杆向外倾斜设置。利用该防脱抛钩器配合气动抛绳器或者直接手动抛投,可实现恶劣海况条件下将远距离及近距离顺利勾连漂浮绳索并回收绳索连接的水下设备。实际使用效果表明,该防脱抛钩器工作原理简单、操作使用轻便,防脱挡片可更换,防脱抛钩器可立即重复使用,能够大大提高水下设备回收的效率和成功率。
