In the description of the present invention, directional descriptions such as directions or positional relationships indicated above, below, front, rear, left, right, etc. are based on the directions or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and thus should not be construed as limiting the present invention.
If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
Before embodiments of the present invention are described, some relative terms are explained. The screwing length (screwing length of screw thread) refers to the length of the connection of two mating threads. The screwing length of the threads determines the reliability of the connection of the threaded parts.
As shown in fig. 1, 2, 3 and 4, an embodiment of the present invention provides a suction port for a ship, including a first pipe 1, a second pipe 2 and a locker 3, the second pipe 2 communicating with the first pipe 1, and the second pipe 2 being movable in an axial direction of the first pipe 1; a locking member 3 is connected to the first tube 1 and the second tube 2, the locking member 3 being capable of locking or unlocking the relative axial movement of the second tube 2 and the first tube 1.

Specifically, the second pipe 2 is in communication with the first pipe 1 such that liquid may exit or enter the hold through the second pipe 2 and the first pipe 1 in sequence to achieve the desired function of the hold. The second pipe 2 moves along the axial direction of the first pipe 1, so that the whole length of the marine suction inlet is shortened or prolonged, the length of the marine suction inlet is adjustable, the marine suction inlet can be installed under the conditions that the number of broken pipes is not increased and pipeline paint is not damaged, the installation cost of a shipyard is saved, and the construction amount of workers is reduced. The locking piece 3 is connected with the first pipe 1 and the second pipe 2 when the second pipe 2 moves to a specific position, namely when the length of the marine suction inlet meets the requirement, so that the second pipe 2 is locked to continuously move along the axial direction of the first pipe 1, the locking between the first pipe 1 and the second pipe 2 is realized, the marine suction inlet can keep the length, and the cabin can be helped to realize the due function.
The upper end of the first pipe 1 and the lower end of the second pipe 2 can form a bell mouth 23 according to the requirement of actual situation, so as to reduce the friction resistance loss of the pipeline.
The locking member 3 may be a conventional rod-shaped member such as a bolt.
The manner of moving the second pipe 2 along the axial direction of the first pipe 1 may be: as shown in fig. 1, 3 and 4, the lower end of the first pipe 1 is provided with a first thread 11, the upper end of the second pipe 2 is provided with a second thread 21, and the first pipe 1 and the second pipe 2 are connected by the threads.
It will be appreciated that the first pipe 1 and the second pipe 2 connected by the first thread 11 and the second thread 21, the second pipe 2 can be adjusted in rotation relative to the first pipe 1 by means of the engagement between the first thread 11 and the second thread 21 during the adjustment of the length, and in this embodiment, the screw engagement length between the first thread 11 and the second thread 21 is adjusted by screwing the second pipe 2, and the size of the screw engagement length determines the length of the marine intake. Generally, the longer the screw engagement length, the shorter the marine intake port. According to the needs of actual conditions, the length of the marine suction inlet is adjusted by adjusting the screwing length, and then the locking piece 3 is connected with the first pipe 1 and the second pipe 2 to lock the second pipe 2 to rotate relative to the first pipe 1 so as to keep the length of the marine suction inlet.
In the above embodiment, the first pipe 1 and the second pipe 2 are connected by the screw thread, so that the effect of the axial movement of the second pipe 2 along the first pipe 1 is achieved by the relative rotation between the first pipe 1 and the second pipe 2, the locking member 3 is arranged to be connected with the first pipe 1 and the second pipe 2, the locking member 3 can lock or unlock the second pipe 2 to rotate relative to the first pipe 1, the length of the marine suction inlet can be fixed, and the phenomenon that the length of the marine suction inlet is changed due to the rotation of the second pipe 2 relative to the first pipe 1 in the subsequent use process is avoided. Preferably, a sealing filler can be filled between the first thread 11 and the second thread 21 to improve the sealing performance of the joint of the first pipe 1 and the second pipe 2, so that the liquid in the cabin can smoothly enter or leave the cabin through the marine suction port to realize the proper function of the cabin. The first thread 11 may be an external thread or an internal thread, and both of the two embodiments can achieve the effect of adjusting the length of the marine suction inlet, which is not described herein again.
In the above embodiment, the first pipe 1 is provided with the first flange 12, the second pipe 2 is provided with the second flange 22, and the locking member 3 is detachably connected to the first flange 12 and the second flange 22.
It will be appreciated that the retaining member 3 is removably attached to the first and second flanges 12, 22 to fix the length of the marine intake. Specifically, when the locking member 3 is detached from the first and second flanges 12 and 22, the second pipe 2 can be rotated with respect to the first pipe 1 by the first and second threads 11 and 21 to adjust the length of the suction port. When the locking member 3 is engaged with the first and second flanges 12 and 22, the first and second flanges 12 and 22 are relatively fixed, that is, the first pipe 1 cannot rotate with respect to the second pipe 2, which can maintain the length of the marine intake.
The connection mode of the locking member 3 with the first flange 12 and the second flange 22 can be as follows: the first flange 12 is provided with threads, the second flange 22 is provided with through holes, and the locking member 3 is in threaded connection with the first flange 12 through the through holes, thereby locking the second pipe 2 to rotate relative to the first pipe 1.

It can be understood that the thread connection of the locking member 3 and the locking nut 4 maintains a contact and extrusion state between the threads by the pulling force of the locking member 3, so as to achieve a sealing effect. On the one hand, the first pipe 1 and the second pipe 2 can be fixed, so that the second pipe 2 cannot rotate relative to the first pipe 1, on the other hand, the threaded connection also fixes the position relation between the locking nut 4 and the locking piece 3, the locking nut 4 is matched with the first hole and the second hole, and after the threaded connection fails, the second pipe 2 can be prevented from moving axially relative to the first pipe 1, so that the second pipe 2 is prevented from being separated from the first pipe 1.
In addition, the method for improving the stability of the locking member 3 when it is connected to the first flange 12 and the second flange 22 further includes: the number of the first holes is more than two, and the first holes are distributed along the circumferential direction of the first flange 12; the number of second holes is matched with the number of first holes, and the second holes are distributed along the circumferential direction of the second flange 22; the number of retaining members 3 and retaining nuts 4 matches the number of first holes. Through a plurality of retaining members 3 with the first flange 12, the second flange 22 and the lock nut 4 that correspond cooperate, can effectively improve the stability that meets. Preferably, the number of first holes is two.
In the above embodiment, the first thread 11 is an external thread, and the first flange 12 is farther from the lower end of the first pipe 1 than the first thread 11; the second thread 21 is an internal thread; a first flange 12 is located at the upper end of the second tube 2. It will be appreciated that the shorter distance between the first flange 12 and the second flange 22, arranged in the manner described above, and correspondingly the shorter length of the retaining member 3, results in a saving in manufacturing costs.
Embodiments of the present invention also provide a marine vessel comprising a hull and a marine intake as in the previous embodiments, with a gap between the lower end of the second tube 2 and the floor of the hold.
The marine suction inlet is arranged in the cabin to adjust the gap between the marine suction inlet and the bottom plate, so as to achieve the effects of the foregoing embodiments, and the description is omitted here.
One of the installation methods of the embodiment of the invention is as follows: preparing a pipe with threads, a bell mouth 23, a flange, a bolt and a locking nut 4; selecting a proper external thread pipe to be welded with a flange to form a first pipe 1; selecting a proper internal threaded pipe to be welded with the flange to form a second pipe 2; connecting the external thread pipe with the internal thread pipe through threads to adjust the length of the whole body formed by the external thread pipe and the internal thread; and after the overall length reaches the length required by installation, finely adjusting the second pipe 2 to align the first hole of the first flange 12 with the second hole on the second flange 22, and then penetrating a bolt through the first hole and the second hole to be in threaded connection with the locking nut 4 to complete installation.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
