Detailed Description
The invention develops a mechanical underwater depth-fixing releaser based on the principle that the pressure difference applied to objects with different cross-sectional areas at two ends is correspondingly changed under the condition of the change of the external environment pressure. The releaser does not need to adopt any sensor and electronic equipment, and the operation is very reliable and stable. The following detailed description refers to the accompanying drawings.
As shown in fig. 1-2, a mechanical underwater depth-fixing releaser comprises a columnar shell 1, wherein a movable block 2 is arranged in an inner cavity of the shell 1, the sectional areas of two ends of the movable block 2 are different, and a trigger mechanism 3 is arranged at the bottom of the movable block 2. The cavity inside the shell 1 is communicated with the external environment, namely the movable block 2 receives a pressure difference under the seawater pressure, and a first spring 4 which is applied to the movable block and is opposite to the pressure difference is arranged between the movable block 2 and the shell 1. Along with the change of the sea water pressure, when the pressure difference reaches a set critical point, the movable block 2 moves downwards under the action of the pressure difference and pushes the trigger mechanism 3 to make some mechanical action, so that the designated work is completed.
As a further improvement of the present invention, the movable block 2 includes a first movable block 201, a second movable block 202, and a third movable block 203, the first movable block 201 having a cross-sectional area larger than that of the third movable block 203, and the second movable block 202 being located between the first movable block 201 and the third movable block 203. The second movable block 202 is inverted i-shaped, and the bottom end of the first movable block 201 and the top end of the third movable block 203 respectively prop against two sides of the i-beam of the second movable block 202. The third movable block 203 has an elongated cylindrical structure. The first limiting boss 101 is arranged on the shell 1, and the first limiting boss 101 can prevent the second movable block 202 from moving too long under the pushing of the pressure difference on one hand, and can play a role in bearing pressure on the other hand, namely, when the pressure difference is too large, the pressure can be transferred to the shell 1 through the first movable block 201 and the second movable block 202. The first spring 4 is sleeved on the third movable block 203, and a second limiting boss 2031 is provided on the third movable block 203, which can prevent the first movable block 201, the second movable block 202 and the third movable block 203 from moving reversely under the resistance of the first spring 4.
Further, the third movable block 203 is provided with a thread, and is provided with a back and forth adjustable nut 5 thereon, one end of the first spring 4 is fixed on the nut 5, and the other end of the first spring 4 is fixed on the housing. Thus, by adjusting the position of the nut 5 on the third movable block 203, the compression amount of the first spring 4, that is, the resistance of the first spring 4, can be adjusted.
More specific settings are as follows: the top of the shell 1 is provided with a first water inlet hole 102, a first water storage cavity 103 is reserved between the first water inlet hole 102 and the first movable block 201, and the cross-sectional area of the bottom of the first water storage cavity 103 is the same as that of the first movable block 201. The bottom of the shell is provided with a second water inlet hole 104, and the second water inlet hole 104 is communicated with a second water storage cavity 105 at the tail end of the third movable block. The tail end of the third movable block is hemispherical, and the triggering mechanism 3 is arranged at the tail end of the third movable block.
Further, a sealing ring 6 is arranged between the movable block 2 and the shell 1, so that the movable block is only subjected to the pressure of seawater on the upper surface and the lower surface.
Further, the triggering mechanism 3 includes an upper rotating portion 301 and a lower rotating portion 302, a second spring 303 is disposed between the same ends of the upper rotating portion 301 and the lower rotating portion 302, a hook head 304 is disposed at the other end of the upper rotating portion 301, and a bayonet matched with the hook head is disposed at the other end of the lower rotating portion 302. An object 7 to be thrown is mounted between the upper rotating portion 301 and the lower rotating portion 302. Under the action of the pressure difference, when the movable block 2 moves downwards, the upper rotating part 301 rotates around the rotating shaft 305, so that the hook head 304 is separated from the bayonet. The lower rotating portion 302 rotates around the rotating shaft 306 under the action of gravity, thereby releasing the object 7 to be thrown.
Further, a fixing ring 8 is also provided on the housing 1 to facilitate its connection and fixation to a submersible or underwater cross-section instrument or the like.
The related technical content which is not described in the mode can be realized by adopting or referring to the prior art.
It should be noted that any equivalent or obvious modification made by those skilled in the art under the teachings of this specification shall fall within the scope of this invention.
