Description

Technical Field

[0001] The present invention relates to the technical field of engineering ship positioning, and more specifically, the present invention relates to a positioning device for inland river dredging engineering ships. Background Art

[0002] Ship positioning refers to a positioning method that keeps a ship or floating platform in a set position or orientation.

[0003] Currently, engineering ships mostly use an anchor mooring system for positioning and ship movement. Due to the defects of the system itself, under the conditions of large working water depth and strong wind and waves, the ship drifts with the waves, and it is difficult for the ship to achieve accurate positioning. Therefore, it is only possible to choose to operate during periods of small wind and waves, greatly reducing the ship operation efficiency, and the construction quality cannot be guaranteed.

[0004] In addition, due to the shape of the existing ship anchor, every time the anchor is retrieved, the ship has to turn its hull, then loosen the anchor, and then move backward a certain distance to loosen the anchor that was originally fixed below the water surface, so as to facilitate retrieving the anchor. This process is very time-consuming, to a certain extent affecting the progress of work, and these movements to cooperate with anchor retrieval will also consume fuel and increase costs. Summary of the Invention

[0005] The purpose of the present invention is to provide a positioning device for inland river dredging engineering ships that can change the fixing method according to the water depth; can reduce the anchor retrieval time and save fuel; and can be easily stored, to solve the above problems.

[0006] The technical solution adopted by the present invention to solve this technical problem is: a positioning device for inland river dredging engineering ships, including: a main body frame, in which a first working cavity is fixedly connected;

[0007] An electric pull rod is arranged in the first working cavity, and one end of the electric pull rod is fixedly connected with a special-shaped tooth rod;

[0008] On one side of the special-shaped tooth rod, a first shaft rod is arranged, a first gear is arranged on the first shaft rod, and a first anchor body is fixedly connected to the first gear;

[0009] On the other side of the special-shaped tooth rod, a second shaft rod is arranged, a second gear is arranged on the second shaft rod, and a second anchor body is fixedly connected to the second gear.

[0010] Preferably, it further includes a receiver for controlling the electric pull rod.

[0011] Preferably, a second working cavity is fixedly connected in the first working cavity, and a third working cavity is arranged in the second working cavity;

[0012] A through-hole A is provided on the first working cavity, and a through-hole B is provided on the second working cavity. The through-hole A and the through-hole B are communicated, and a through slot is provided on the third working cavity to penetrate the second working cavity;

[0013] At the upper end of the inner wall of the third working cavity, a push switch is provided. The push switch is used to control the electric pull rod. A floating ball is arranged in the third working cavity, and a metal block is arranged in the floating ball. An electromagnet is arranged in the second working cavity and on the inner bottom surface of the third working cavity. The electromagnet adsorbs / releases the floating ball by energizing / de-energizing.

[0014] Preferably, an auxiliary block is fixedly connected to one side of the main body frame, and a rope is fixedly connected to the auxiliary block.

[0015] Preferably, a receiver is arranged on the auxiliary block;

[0016] The receiver is used to control the electric pull rod and the electromagnet.

[0017] Preferably, the push switch is a pressure switch. When the pressure value of the floating ball on the pressure switch is greater than a set threshold, the pressure switch outputs a control signal, and the electric pull rod extends according to the control signal, so that the first anchor body and the second anchor body open to a set angle.

[0018] The present invention has at least the following beneficial effects:

[0019] 1. When the water level is relatively deep in the present invention, the outward expansion of the first anchor body and the second anchor body will become larger, and the deeper the first anchor body and the second anchor body with a larger outward expansion are inserted into the soil, so that the ship can be fixed more firmly. That is, the opening and closing angle of the first anchor body and the second anchor body can be changed by the different water pressures received by the floating ball, so as to adapt to the water level at this time and increase the positioning effect;

[0020] 2. When the anchor is to be retracted in the present invention, as long as the transmitter on the ship sends a signal to the receiver, the receiver will control the electric pull rod to indirectly drive the special-shaped tooth rod to move, so that the outward-expanded first anchor body and the second anchor body are retracted into the first working cavity again through the first gear and the second gear. This setting is different from the traditional situation that every time the anchor is retracted, the ship has to rotate the hull, then loosen the anchor, and then move backward a certain distance to loosen the anchor originally fixed below the water surface. This makes it convenient to retract the anchor, effectively saves time, speeds up the overall work progress to a certain extent, and does not need to move to cooperate with the anchor raising, so it also saves some fuel and reduces costs;

[0021] 3. Through the design of the overall device of the present invention, when not in use, the included angle between the first anchor body and the second anchor body is at the minimum value at this time, that is, at this time, the first anchor body and the second anchor body are retracted in the main body frame. At this time, the width of the device is only the width of the main body frame. This width is relatively smaller in volume than the traditional non-recyclable setting of the first anchor body and the second anchor body, and is convenient for storage without occupying space.

[0022] Other advantages, objectives, and features of the present invention will be partially reflected by the following description and partially understood by those skilled in the art through the research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

An electric pull rod 5 is arranged in the first working cavity 2, and one end of the electric pull rod 5 is fixedly connected with a special-shaped toothed rod 6; a first shaft rod 7 is arranged on one side of the special-shaped toothed rod 6, a first gear 8 is arranged on the first shaft rod 7, and a first anchor body 9 is fixedly connected to the first gear 8; a second shaft rod 10 is arranged on the other side of the special-shaped toothed rod 6, a second gear 11 is arranged on the second shaft rod 10, and a second anchor body 12 is fixedly connected to the second gear 11. There is a signal control relationship between the electric pull rod 5 and the receiver 22,

[0044] A through hole A13 is provided on the first working cavity 2, a through hole B14 is provided on the second working cavity 3, the through hole A and the through hole B are communicated, and a through slot 15 is provided on the third working cavity 4 to penetrate the second working cavity 3;

[0045] A push switch 16 is provided at the upper end of the inner wall of the third working cavity 4, the push switch is used to control the electric pull rod 5, a floating ball 17 is arranged in the third working cavity 4, a metal block 18 is arranged in the floating ball 17, and an electromagnet 19 is arranged on the inner bottom surface of the third working cavity 4 in the second working cavity 3. The receiver is used to control the electric pull rod 5 and the electromagnet 19, and the electromagnet adsorbs / releases the adsorption of the floating ball by energizing / de-energizing. Wherein, the width of the third working cavity is preferably equal to or slightly larger than the diameter of the floating ball to ensure that the floating ball can accurately float up and press the push switch under the action of buoyancy.

[0046] The through hole A13 is communicated with the through hole B14, a through slot 15 is provided on the third working cavity 4, a push switch 16 is provided at the upper end of the inner wall of the third working cavity 4, and the floating floating ball 17 will abut against the push switch 16. At this time, the push switch 16 will activate the electric pull rod 5, and the electric pull rod 5 will change with the pressing force of the push switch 16 to change the moving distance. When the pressing force of the push switch 16 is greater, the moving distance of the electric pull rod 5 is greater. At this time, the angle between the first anchor 9 and the second anchor 12 is larger. A floating ball 17 is arranged in the third working cavity 4. The deeper the device is, the greater the pressure on the floating ball 17, and the greater the force of the floating ball 17 pushing the push switch 16. A metal block 18 is arranged in the floating ball 17, and an electromagnet 19 is arranged on the inner bottom surface of the third working cavity 4 in the second working cavity 3. The electromagnet 19 can adsorb the metal block 18 when energized. One side of the main body frame 1 is fixedly connected with an auxiliary block 20, a rope 21 is fixedly connected to the auxiliary block 20, and a receiver 22 is arranged on the auxiliary block 20.

[0047] The working principle in Embodiment 3 is as follows:

[0048] In the initial state: there is no water in the second working cavity 3 and the third working cavity 4. The first anchor 9 and the second anchor 12 are received in the main body frame 1. The included angle between the first anchor 9 and the second anchor 12 is at the minimum value at this time. The electromagnet 19 is not energized to adsorb the metal block 18, and the floating ball 17 is located at the bottom of the third working cavity 4.

[0049] During use, the entire device is dropped into the water. As the device sinks, water will enter the third working chamber 4 through the through-hole A13 opened on the first working chamber 2 with the assistance of the through-hole B14 and through the through-slot opening 15. At this time, the float ball 17 originally located at the bottom inside the third working chamber 4 will float to the top of the third working chamber 4 under the buoyancy of the water, and thereby press against the push switch 16 provided at the top inside the third working chamber 4. At this time, the pressed push switch 16 will activate the electric pull rod 5. After the electric pull rod 5 is activated, it will pull the special-shaped toothed rod 6 provided at one end. As the special-shaped toothed rod 6 is pulled in the direction gradually entering the first working chamber 2, the special-shaped toothed rod 6 will cause the first gears 8 on both sides and the second gear 11 to rotate towards each other through its teeth. During this rotation, the angle between the first anchor body 9 fixed on the first gear 8 and the second anchor body 12 fixed on the second gear 11 will gradually increase, that is, at this time, the first anchor body 9 and the second anchor body 12 will expand out from the main body frame 1, and thereby get stuck between the stones as the ship moves, so as to fix the ship;

[0050] Furthermore, if the water level here is relatively deep, the greater the force exerted by the float ball 17 floating in the third working chamber 4 on the push switch 16. Also, since the electric pull rod 5 will change the moving distance according to the pressing force of the push switch 16, when the pressing force of the push switch 16 is greater, the moving distance of the electric pull rod 5 is greater. At this time, the angle formed between the first anchor body 9 and the second anchor body 12 is greater, that is, when the water level is relatively deep, the outward expansion of the first anchor body 9 and the second anchor body 12 will be larger, and the depth at which the larger outward-expanded first anchor body 9 and second anchor body 12 are inserted into the soil will be deeper, so as to fix the ship more firmly. That is, by the different magnitudes of the water pressure received by the float ball 17, the opening and closing angle between the first anchor body 9 and the second anchor body 12 can be changed, so as to adapt to the water level at this time and increase the positioning effect;

[0051] Furthermore, when wanting to retract the anchor, as long as the transmitter on the ship sends a signal to the receiver 22, the receiver 22 will energize the electromagnet 19. The energized electromagnet 19 will adsorb the float ball 17 from the upper part of the third working chamber 4 to the bottom of the third working chamber 4 by adsorbing the metal block 18. Further, the receiver 22 will control the electric pull rod 5 to indirectly drive the special-shaped toothed rod 6 to move, so as to indirectly retract the outward-expanded first anchor body 9 and second anchor body 12 back into the first working chamber 2 through the first gear 8 and the second gear 11. Such a setting is different from the traditional situation where every time the anchor is retracted, the ship has to turn the hull, then loosen the ship anchor, and then move a certain distance in the reverse direction to loosen the ship anchor originally fixed below the water surface. This makes it convenient to retract the anchor, effectively saves time, speeds up the overall work progress to a certain extent, and there is no need to move to cooperate with raising the anchor, so it also saves some fuel and reduces costs;

[0052] Further, before use, that is, when the whole device has not been thrown into water, the included angle between the first anchor body 9 and the second anchor body 12 is at its minimum value at this time, that is, the first anchor body 9 and the second anchor body 12 are retracted in the main body frame 1 at this time. At this time, the width of the device is only the width of the main body frame 1. This width is relatively smaller in volume than the non-recyclable setting of the traditional first anchor body 9 and second anchor body 12, and is convenient for storage without occupying space.

It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made.
