Description

Description Outboard work assist device and adapter for outboard work assist device

The present invention works on a propulsion device outside the hull through a work port provided on the bottom of the ship for maintenance and inspection of the propulsion device of the ship, and detaches and attaches a device mounted through the bottom of the ship. Related to the equipment used when Background art

Ship propulsion devices, especially propellers, are apt to adhere to shellfish and seaweed. Even if they adhere to the propeller, the propulsion force is significantly reduced, causing an increase in fuel cost and an increase in vibration of the hull. In addition, seaweed, vinyl, rope, etc. are often entangled with propellers and hinder navigation.

These debris can be lifted off the ship or removed underwater.These methods have cost and safety concerns and must be performed from the ship. When working from the inside of the ship where the method is being carried out, a universal joint should be provided in the middle of the propeller shaft that supports the propeller, and at the bottom on the propeller An opening that allows the propeller to pass through is provided, and this opening is surrounded by a waterproof wall. Then, when removing the deposits on the propeller, bend the propeller shaft upward from the universal joint, pull up the propeller from the opening to the ship, and remove the deposits. Removed.

As another method, an inspection port and inspection lid are provided on the bottom of the ship above the propeller, and the surrounding area is enclosed with a waterproof wall to remove any deposits on the propeller. When removing, there is a method to open the inspection lid and remove the deposit directly from the propeller. In addition, in each of the above methods, seawater does not enter the ship because the water flowing from the opening or inspection port is collected in the waterproof wall.

In addition to the work to remove deposits on propellers and other propulsion devices, flow velocity sensors and water depth measurement devices that are installed through the bottom of the ship as work from inside the ship to the outside of the ship bottom Removing, inspecting, and cleaning may be the case. In this work, when the area of the penetration is small, it is necessary to know that a large amount of water will flow into the ship, to quickly install a substitute plug, and then work. Also in this work, there is a case where the above-mentioned waterproof wall is provided around the through-hole and water is stored in the waterproof wall to perform the work.

At this time, if the water barrier is used as described above for work on the outside of the bottom of the ship, if the propeller is lifted up, the area surrounded by the waterproof wall should be sufficient to accommodate the propeller. Must be taken. Also, when working on the propulsion device on the bottom of the ship from the inspection port, seawater is filled up to the waterline in the waterproof wall, so the object on the bottom of the ship must be seen from a position away from the draft. No. Therefore, in order to secure a sufficient field of view, it is necessary to widen the inspection area and surround the wide area with a waterproof wall.

However, when such unused waterproof walls occupy a large area in the ship, it becomes impossible to efficiently use the narrow ship interior. If a waterproof wall is used, it will be necessary to drain the water accumulated in the waterproof wall after the work is completed. And the cost of installing a waterproof wall is also required. In addition, when working on an object at the bottom of the ship, which is far away from the object by the distance of the draught, it is difficult to see the object due to the waves on the water surface and the turbidity of the water caused by the motion of the ship This There is also.

On the other hand, when attaching and detaching a penetrating body such as a sensor that penetrates the bottom of a ship without providing a waterproof wall, the above-mentioned problem does not occur because there is no waterproof wall. There is an annoyance of draining water that has penetrated into the water and cleaning up things that are in trouble with the water, and it is also possible to break down sensors etc. in order to quickly stop the inflowing water. is there. Disclosure of the invention

By fixing the flange 26 to the bottom of the ship with screws, etc., the adapter Y1 is fixed to the ship bottom. The bottom of the ship, the flange, and the hole 25 are sealed with a sealant or the like so that there is no gap.

Next, the outboard surface work assisting device X1 will be described. The outboard surface work assist device X 1 is a waterproof tube 11 that is the main body of the device that forms an internal space with a water-proof surface layer, and an insertion port through which the worker's arm passes from the outside to the inside of the waterproof tube 11. As a part of the working port, which is waterproofly engaged with the sleeve 12 as the sleeve 12 and the watertight casing 11. It is composed of a sealing port 13 for communicating between and, a communication pipe 14 for communicating with the inside of the waterproof tube 11, and a stop valve 15 provided at the end of the communication pipe 14.

The waterproof cylinder 11 is a tapered cylindrical body made of a transparent and flexible plastic sheet forming a surface layer, and has a flat bottom surface. It is closed by the bottom 11a to form an internal space. On the bottom 11a, an alternative plug 101a 'for closing the through hole 101 after the sensor 101a is extracted, a work tool, and the like can be placed.

The sleeve 12 is a cylindrical body having a tapered shape downward, and is adhered and fixed to the upper part of the waterproof cylinder 11. The sleeve 12 uses elastic members such as rubber, so that when the worker inserts the arm into the sleeve 12, the circumference of the arm and the taper of the sleeve 12 are reduced. The inner peripheral surface at the point where the seal becomes tight, and the inside of the waterproof tube 11 can be sealed from the outside.

The sealing opening 13 is attached to an opening provided at the bottom 11a of the waterproof tube 11 and engages the adapter Y1 in a sealable manner. That is, the sealing port 13 is a cylindrical body having an inner peripheral surface substantially matching the outer circumference of the mounting port 21 of the adapter Y 1. When the sealing port 13 is fitted into the mounting port 21 of the adapter Y 1, An O-ring provided on the outer periphery of the adapter Y1 seals the joint between the sealing port 13 and the adapter Y1. In addition, three guide pins 13 a having a length and a thickness to be engaged with the groove 23 of the adapter Y 1 are provided symmetrically with respect to the circumference on the inner peripheral surface of the sealing opening 13. That is, the guide pin can enter the groove 23 through the three cutouts 23 a formed in the groove 23.

The communication pipe 14 is a tubular body made of a flexible synthetic resin material, and is a stop valve 1 provided at the end of the communication pipe 14 which is joined to the side surface of the waterproof cylinder 11 in a sealed state. 5 has an air inlet 15b for sending air into the waterproof tube 11 through the communication pipe 14 and an operation button 15a for the operator to open and close the valve. . In use, an air compressor is connected to the inlet 15b. Pressing the operation button 15 a opens the valve. Release the button 15a so that the valve closes.When the air compressor is operating, press the operation button 15a to put air into the waterproof tube 11 When the operation button 15a is released, the air pressure inside the waterproof cylinder 11 can be maintained. Subsequently, a method of using the outboard surface work assisting device X1 and the adapter Y1 having the above structures will be described. Here, it is assumed that the sensor 101a is taken out from the bottom of the ship and the hole 101aa 'is temporarily plugged into the hole taken out. It is assumed that an air compressor has already been connected to the inlet 15b of the stop valve 15.

At first, an alternative plug 1001a 'with the same sealing function as the sensor 101a, which was installed through the bottom of the ship, and the necessary tools for attachment and detachment, etc. a Place it on the top or in the mounting port 2 1 of the adapter Y 1.

Next, while fitting the inner circumference of the sealing port 13 of the waterproof cylinder 11 to the outer circumference of the mounting port 21 of the adapter Y 1, turn the entire device and rotate the three pipes provided on the inner circumference of the sealing port 13. Insert the guide bin 13a into the adapter bin 13a by pressing the sealing hole 13 as it is into the three notches 23a provided at the upper part of the outer periphery of the adapter Y1 shown in Fig. 2. Put it in the groove 2 3 of Y 1. Then, by rotating the entire device horizontally and rotating the guide bin 13a along the groove 23, the outer surface work assisting device X1 is fixed to the adapter Y1 in a sealed state.

When the arm is passed through the sleeve 12 in this state, the arm and the sleeve 12 come into close contact with each other due to the elasticity of the sleeve 12, and the interior of the anti-icing cylinder 11 is cut off from the space inside the ship. You. Next, press the operation button 15a of the stop valve 15 to open the stop valve and send air into the waterproof tube 11 through the communication pipe 14.The seawater near the bottom of the ship enters the waterproof tube 11 Apply a pressure slightly higher than the water pressure. In this state, remove sensor 101a. At this time, seawater does not enter the waterproof case 11 due to the air pressure in the waterproof case 11. In addition, since the waterproof cylinder 11 is made of flexible soft plastic, even when the arm is moved during work, the sleeve 12 and the arm are almost in close contact with each other, and almost no air leaks. Absent.

Next, a plug 101a 'is attached to the through hole 101 after removing the sensor 101a. After that, the arm is removed from the sleeve 12, the sealing opening 13 is removed from the adapter Y 1, and the sensor 101 a extracted earlier is removed, and the operation is completed. When the work is not being carried out in this way, the waterproof tube 11 can be removed from the adapter Y1 so that it does not interfere. When the work is not in progress, it is possible to improve the safety and sealing performance of the work port by sealing the adobe Y1 with the same shape as the seal port 13 and a lid on the top. Can be. This is the same for the adapter Y2.

If the draft is lower than the height of the open face of the sleeve 12 when the waterproof cylinder 11 is extended, raise the waterproof cylinder 11 to the state shown in Fig. 2. Remove the sensor 10 la attached through the bottom 100 of the ship and remove the arm from the sleeve 12 without opening the plug 10 la ′. Seawater does not enter the ship without overflowing. In this case, the seawater that has entered the waterproof tube 11 passes through the arm again to the sleeve 12 and sends air into the waterproof tube 11 through the communication pipe 14 to outboard. Is discharged.

Next, the outer surface work assisting device X2 and the adapter Y2 will be described. Fig. 4 shows a vertical cross-sectional view of the adapter Y2 with the inspection lid removed, and Fig. 5 shows a vertical cross-section of the separated outboard work assisting device X2 and adapter γ2 with the inspection lid removed.

First, the adapter Y2 will be described. Adapter Y 2 is shown in the figure It is installed so as to cover the inspection port 102 as a working port as shown. The adapter Y 2 has almost the same configuration as that of the adapter Y 1 except that an inspection lid is provided. However, the size of the adapter Y2 is larger than that of the adapter Y1 because the inspection port 102 is formed large enough to allow the arm for work to pass through. When the adapter Y2 is attached to the inspection port 102, the inside surface of the adapter Y2 becomes a working port that connects the inside and outside of the hull, and the inspection lid is fitted to the inside surface, and this working port is connected. It is designed to be sealed. In the adapter Y2, a groove 32 and a groove 33 are formed along the outer peripheral surface of the cylindrical mounting opening 31 near the outer periphery of the outer periphery in parallel, and the groove 32 is engaged with the work assist device X1 on the outboard surface. Rubber o-rings 34 are fitted to make it sometimes sealed. In addition, a flange 36 is formed on the lower surface of the mounting port 21 so that the mounting port is attached to the ship bottom provided with the inspection port 102 so as to be in close contact therewith. By fixing the flange 36 to the bottom of the ship with screws or the like, the adapter Y2 is fixed to the bottom of the ship. The groove 32 is located on the upper side unlike the adapter Y1 in which the O-ring is provided in the adapter Y2.

The inspection lid 40 is a ring-shaped main body 41 having an outer peripheral surface having substantially the same diameter as the inner peripheral surface of the mounting port 31, and a groove formed along the outer peripheral surface of the main body 41. 4 2, O-ring 4 3 for sealing fitted in the groove 4 2, Handle 4 4 fixed to the body 4 1 4, Transparent fitted tightly so as to close the hole in the center of the body 4 1 It consists of a viewing window 45 made of a pressure-resistant glass. By attaching the observation window 45 to the inspection lid 40 in this way, the state near the propulsion device can be confirmed without opening the inspection lid 40.

The outboard surface work assisting device X2 has substantially the same configuration as the outboard surface work assisting device X1. The differences are the size of the waterproof tube 11, the mounting position of the communication pipe 14, and the configuration of the sealing port 13. ship The sealing port 13 of the external work assisting device X 2 is a cylindrical body having an inner peripheral surface whose sealing port substantially matches the outer circumference of the mounting port 31 of the adapter Y 2 .The sealing port 13 is connected to the adapter Y 2 When it is fitted to the mounting port 21 of the adapter Y 2, the joint between the sealing port 13 and the adapter Y 2 is sealed by an O-ring provided on the outer periphery of the adapter Y 2. Also, unlike the adapter Y1, three mounting screws 13b are provided to engage the groove 33 from the outer peripheral surface of the sealing opening 13 to the inner peripheral surface side. By pressing the inside of the groove 33 of the adapter Y2 with the screw 13b, the sealing opening 13 can be fixed to the adapter Y2.

How to use the outboard surface work assisting device X2 and adapter Y2 having the above-described configuration will be described. First, it is assumed that the state of the propeller, which is the propulsion device, is inspected through the viewing window 45 of the inspection lid 40, and it is determined that cleaning is necessary. It is assumed that an air compressor has already been connected to the inlet 15b of the stop valve 15.

First, fit the inner circumference of the sealing port 13 of the waterproof cylinder 11 into the outer circumference of the mounting □ 31 of the adapter Y 2, and turn the mounting screw 13 b of the sealing port 13 in the fastening direction to tighten the sealing port 13. Securely sealed to adapter Y2. Next, the arm is passed through the sleeve 12 and the operation button 15 a of the stop valve 15 is pressed to blow air into the waterproof cylinder 11. Then, remove the inspection lid 40 and place it on the bottom 11 a of the waterproof tube 11, and leave the arm passed through the sleeve 12 as it is to remove the inspection lid 40. The cleaning work of the propulsion device is performed through the working opening created by the above. When the cleaning operation is completed, pull out the arm from the work opening, insert the inspection lid 40 as before, remove the arm from the sleeve 12, and turn the mounting screw 13 b to the open side. Then, the sealing port 13 is removed from the adapter Y2, and the work is completed.

In the above embodiment, the present invention is applied to work on the bottom An outboard work aid was used, but it can also be used for things like water pipes into which fluid flows. In other words, if there is an inspection lid as a working port on the pipe wall or a device penetrated, an adapter is attached to the working port as in the case of the ship bottom, and the vessel By using an external work assist device, work can be performed without leaking fluid to the outside of the pipe.

Subsequently, a modified example of the above-mentioned outer surface work assisting device will be described in a separate article below.

(1) The waterproof tube 11 may be formed in a bellows-like shape so as to easily expand and contract, and in this case, it may be reinforced with a net-like fiber to increase the strength.

(2) If it is difficult to work with one hand, two sleeves 12 may be provided on top of the waterproof tube 11.

(3) As shown in Fig. 6, the lower part of the waterproof cylinder 11 is replaced with a tool placement box 16 using a hard material and having a large volume to make it easier to place the removed inspection lid 40 and tools. You can also do it.

(4) As shown in Fig. 7, instead of the sleeve, waterproof gloves 17 whose fingertips can reach the sealing opening may be attached. By attaching the waterproof gloves 17 in this manner, the inside of the waterproof tube 11 is isolated from the inside of the ship simply by fitting the sealing port 13 and the adapter. For this reason, the sealability is higher than that with the sleeve 12 attached, and the hands and arms of the worker do not come into contact with seawater. In addition, even if the draft exceeds the height of the waterproof cylinder 11, the worker must temporarily remove his arm and leave the place with the outer work aid attached to the adapter during work. Can also.
