Description

[Detailed Description of the Invention] The present invention relates to a float hook device for submerged structures such as fish reefs and blocks.

(Prior art and purpose and structure of the present invention) Conventionally, when sinking objects such as fish reefs and blocks on the seabed or the bottom of a lake, a diver used to connect the object anchored to the lower end of the sling wire and the sling wire. It had been lost to the seabed and had been removed. However, such work is extremely dangerous.

For this reason, a hanging device commonly known as a crow has recently been used, but when slinging, a person must hold down the wire until it becomes taut, which is very dangerous.

In addition, large reefs require multiple sling wires, which increases the weight of the crow, and when the boat rolls, the slinging equipment can swing and become dangerous.

The purpose of the present invention is to eliminate such conventional dangers when removing objects to be sunk from wires. That is, as described below, the present invention provides a float hook 3 below the main hook 10 separately from the main hook 10, and a sling wire 9 that is temporarily engaged and connected to the float hook 3, the object 1 to be sunk, and the main hook 10. When the object 1 to be sunk reaches the bottom of the water, the buoyancy of the float 4 automatically disengages the float hook 3 from the sling wire 9.

By employing such a configuration, the present invention makes it possible to automatically leave the object 1 on the bottom of the water.

(Explanation of Examples) Examples of the device of the present invention will be described below.

In the drawing, 1 is a fish reef, 2 is an auxiliary wire suspended from the main hook 10, 3 is a float hook to which a float 4 is fixed, 4 is a float fixed to the float hook 3, and 5 is the auxiliary wire 2 and the float hook 3. 6 is the reef 1
The sling rope 9 is normally inserted through the sunken object attachment ring. Reference numeral 7 denotes a float hook engagement ring, which is connected to the main hook engagement ring 8 by a sling wire 9. 8 is as mentioned above,
Main hook engagement ring, 9 is the same sling wire, 10 is the main hook at the lower end of the crane wire 11, 11 is the crane wire, 12 is the float 4
13 is the nut of the mounting bolt 12, and 14 is the bottom of the water.

(Explanation of action) Before the fish reef 1 does not reach the bottom Before the fish reef 1 does not reach the seabed 10, the weight of the fish reef 1 is over the sling wire 9 and the auxiliary wire 2, so the float 4 sinks into the sea along with Float Fuku 3.

Finally, in Figure 1, fish reef 1 becomes seabed 10.
reach.

When the fish reef 1 reaches the bottom As shown in Figure 2, when the fish reef 1 reaches the seabed, the weight of the fish reef 1 on the sling wire 9 is removed, so the sling wire 9 becomes slack. Therefore, the tense engagement relationship between the float hook 3 and the float hook engagement ring 6 is relaxed, and the float hook 3 is moved by the buoyancy of the float 4.
trying to escape from

In other words, the buoyancy of the float 4 increases when the load is removed from the sling wire 9.
The size is set to be large enough to rotate the shaft around the shaft 5.

If the buoyancy of the float 4 is made too large, the float hook 3 will float up to the top of the main hook 10, and there is a danger that it will become entangled with the crane wire 11. Therefore, it is necessary to change the magnitude of the buoyancy of the float 4 depending on the suspended load. float 4
is replaceable as shown in FIG.

Floating state of float 4 Due to the buoyancy of float 4, float hook 3
When the sling wire 9 comes out of the float hook engagement ring 7, the crane wire 11 rises and the sling wire 9 rises. Then, the float hook engagement ring 7 is pulled by the sling wire 9 and passes through the deposit attachment ring 6. Thus, the sling wire 9 connects to the main hook engagement ring 7.
At the same time, the fish reef 1 is pulled up by the crane wire 11 and left on the seabed.

(Operations and Effects of the Present Invention) When sinking objects such as the fish reef 1 and blocks, the objects can be left on the bottom of the water without requiring any special labor.

Claims (1)

[Claim for Utility Model Registration] An auxiliary wire 2 is suspended from the main hook 10 of a crane wire 11, and a float 4 is attached to a shackle 5 at the lower end of the auxiliary wire 2, and a float 3 is rotated about the shackle 5. On the other hand, one end is attached to the main hook 10, passes through the attachment ring 6 of the submerged object 1, and the other end is attached to the float hook 3 with the float hook engagement ring 7,
The buoyancy of the float 4 of the float hook 3 is such that when the load is removed from the sling wire 9,
The float hook 3 is set to a size large enough to rotate around the shackle 5, and the float hook engagement ring 7 is connected to the submerged object 1.
When the float reaches the bottom of the water, the weight of the float is not applied to the auxiliary wire 2 and the sling wire 9, and the float hook 3 comes out of the float hook engagement ring 7 due to the buoyancy of the float 4. Float hook device for deposit 1.
