Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an underwater grass 5- used by divers such as scuba diving, and more specifically, to an ice grass! This invention relates to an ice winter A- in which the inside of the housing is divided by a partition plate into a battery chamber, a motor chamber, and a clutch chamber, and these divided chambers are formed so as to be detachable from each other.

[Prior Art] As is well known, skiuba diving and the like are widely practiced. In this case, the diving time and range of movement are limited, although this varies depending on the diver's ability and other factors. Therefore, there is a need for divers to further expand their range of action by increasing their mobility during a single dive, and in order to meet these demands, underwater divers have been developed and put into practical use.

By using this underwater shufter, there is no need to kick compared to when the convex tip itself moves using fins, saving on air consumption and widening the range of action.

Focusing on the above-mentioned underwater service, conventionally, a battery as a power source, a drive motor, a craft, etc. are all housed in a single housing.

In addition, since the seal on the propeller shaft of the underwater station 5- was sealed in one place, it was not uncommon for a small amount of seawater to enter through the seal when the propeller shaft rotated or due to water pressure, etc. .

[Problems to be Solved by the Invention 1] Although the above-mentioned prior art has the advantage of expanding the range of action of scuba divers and other divers while reducing the amount of effort required by the divers themselves, there are still a number of problems that need to be solved. It has some problems.

In other words, ■ the battery, motor,
Since the clutch and the like are housed in the housing, seawater that has entered the housing for some reason will spread throughout the housing.

■Seawater that has entered the housing may corrode the motor, bearings, etc. and cause malfunctions.

Also ■Underwater winter! - Because the seal on the propeller shaft, which is the means of propulsion, is sealed in one place, it is not uncommon for seawater to enter through the seal as the propeller shaft rotates. It is possible to dive to a depth of 50 meters, and as water pressure increases with diving, a certain amount of water pressure is also applied to the seal part of the propeller shaft, making it difficult to completely seal seawater, and some seawater may enter through the seal part. At the same time, it spreads throughout the housing.

Therefore, underwater swimming! - maintenance is difficult.

This is because the seawater that has entered the housing will spread throughout the housing, and the battery, motor, clutch, etc. housed in the housing must all be disassembled, which is difficult work and requires specialized work. Knowledge is required.

In addition, the battery housed in the housing is damaged by the diffusion of seawater that has entered the housing.
This increases the cause of failures in motors, clutches, etc., and deteriorates the durability of each part.

Furthermore, since it is disposed integrally within the housing, it is inconvenient to disassemble and reassemble each part, making it difficult to shorten the working time.

Accordingly, the object of the present invention is as follows: (1) By providing a partition plate in the housing, underwater contact points are formed in the housing into three compartments: a battery chamber, a motor chamber, and a clutch chamber. to provide the tar.

Therefore, it is an object of the present invention to provide an underwater shifter that does not spread seawater that has entered the housing.

Also, by forming the battery chamber, motor chamber, and clutch chamber in the housing independently, if seawater were to enter one housing, the seawater would flow from one compartment to the other. To provide an underwater winter bar that can prevent water from entering a compartmentalized room.

Also, each room is double-sealed with a sealing member and a partition plate, so it is easy to respond to pressure changes due to water pressure, etc., and even if seawater enters one room, it is prevented from entering other rooms. It is possible to provide underwater scooters.

Therefore, the object of the present invention is to provide a means that can facilitate the maintenance of the underwater slide itself.

In other words, the battery compartment, motor compartment, and clutch compartment inside the housing are independent and can be attached and detached at will for an underwater winter! - to provide.

The object of the second invention of the present application is to: In addition to enabling the above-mentioned items (1), (2), (2), and (2), (1) an underwater vehicle that can be attached and detached with one touch by using a bayonet system for the clutch chamber; is to provide.

Therefore, it is an object of the present invention to provide an underwater vehicle in which maintenance of the clutch chamber can be performed more easily since the clutch chamber can be attached and detached with a single touch when seawater enters the clutch chamber as the propeller shaft rotates.

[Means for Solving the Problems] The present invention has the following technical means to achieve the above object. That is, to explain using the reference numerals used in the attached drawings corresponding to the embodiments, the first invention of the present application is directed to an underwater shifter used by divers such as scuba divers, which has a battery, a drive motor, a clutch, etc. in a housing.

A clutch chamber C is defined by the second partition plate 17 and the clutch housing 5. A propeller shaft 34 is rotatably attached to the clutch chamber C with a bearing 32 interposed therebetween. The distal end thereof has a substantially cylindrical shape, and is formed so as to be able to fit into the tail end of the clutch shaft 31 described above. Further, a propeller variable pitch dial 38 is provided on the rear end side of the clutch housing 5, and a plurality of propellers 39 are rotatably attached to the propeller variable pitch dial 38. A propeller shaft seal 40 is attached to the propeller shaft 34 at the end of the clutch housing 5.
This is to prevent seawater from entering due to rotation.

Next, when connecting the battery housing 3, motor housing 4, and clutch housing 5 described above,
First, the uneven portion 42 formed on the open end 41 of the battery housing 3 and the uneven portion 44 on the open end 43 of the motor housing 4 are fitted together. At this time, the uneven surface 44 has an O

Furthermore, O-rings 24 are provided at positions where both ends 23 of the first partition plate 16 are in contact with the inner surface 25 of the motor housing 4.
By using the sealant 43 outside the battery compartment, even if seawater enters the battery compartment A due to some malfunction, the first
The partition plate 1B, the sealant 48, and the O-ring 24 work together to prevent seawater from entering the motor room B.

Further, since the above-mentioned joint between the clutch housing 5 and the motor housing 4 is made of a bayonet type, it is possible to easily remove the clutch housing 5 by raising the crank lock lever 49 and turning the clamp ring 50 counterclockwise.

Furthermore, the propeller shaft seal 40 described above is 2 in this example.
Since it is made of a heavy structure, it is possible to suppress as much as possible seawater that enters into the clutch chamber C due to the rotation of the propeller shaft 34 or the water pressure associated with diving.

Next, an example of how this embodiment is used will be explained.

In this example, it is shown as an underwater squeezing g-1 to expand the range of action and make movement easier when diving like a scuba diver. It is formed into three parts, each consisting of a battery housing 3, a motor housing 4, and a clutch housing 5 from the front part to the rear part, and a first partition plate 18 is disposed between the battery housing 3 and the motor housing 4. motor housing 4
A second partition plate 17 is disposed between the clutch housing 5 and the first partition plate 1B and the clutch housing 5, and a battery chamber A, a motor chamber B, and a clutch chamber C, which are divided into three parts by the first and second partition plates 1B and 17, are each independent. It is formed by Furthermore, the battery chamber A, motor chamber B, and clutch chamber C are each formed to be detachable. Furthermore, when the battery compartment A, motor compartment B, and clutch compartment C, which are divided as described above, are assembled integrally, each compartment is designed to be watertight. That is, a sealing means and a joining means are provided at the joint of each housing, and these sealing means and joining means work together to seal the joint and maintain watertightness within each room.

In the past, the propeller shaft of the underwater shifter was sealed in one place, so it was not uncommon for a small amount of seawater to enter the sealed area when the propeller shaft rotated or due to water pressure. . However, conventional underwater skis have a battery, motor, and
Because the clutches and other components are arranged in a straight line, seawater that has entered through the sealing member of the propeller shaft, for example, can spread throughout the housing, damaging the most important motor or rotating mechanism, such as the bearings. This caused corrosion and caused malfunctions.

In this case, it's thread in the ice! By dividing the housing 2 of -1 into three parts, it has a structure that prevents seawater from entering the motor room B in the center, which is the most important part.

That is, the propeller shaft 34 disposed in the clutch chamber C
By installing a propeller shaft seal 40 in a double structure and further disposing a clutch shaft seal 35 on the clutch shaft 31 connected to this propeller shaft 34, seawater should not leak from the sealing member of the clutch shaft 34. Even if seawater enters the clutch chamber C, the clutch shaft seal 35, second partition plate 17, etc. maintain complete watertightness, so the seawater that has entered the clutch chamber C will not spread to other chambers. .

Similarly, even if seawater were to enter the bar 2 telly compartment A due to some malfunction, the sealant 51 and the O-ring 24 would work together to prevent the seawater from entering the motor compartment B. be. Therefore, each room part, battery room A
The clutch chamber C always prevents seawater from entering the motor chamber B, which is located in the center, and this prevention means has a double structure, so seawater should not enter the housing on either side due to some malfunction. Even if it does enter the housing, it can be prevented from spreading outside the housing.

Furthermore, the underwater submarine G-1 can be submerged to a depth of about 50 m, and water pressure is applied to the propeller shaft seal portion as it dives, and seawater tends to enter the seal portion of the propeller shaft, making it extremely difficult to completely prevent it.

Therefore, the structure is such that the seawater that has entered the clutch chamber C accumulates and cannot enter the motor chamber B unless it passes through the next clutch shaft seal 35. Further, since water pressure is not directly applied to the clutch chamber C, the clutch shaft seal 35 is sealed by having a double seal structure with a good sealing effect.

Furthermore, even if water enters the clutch chamber C, the clutch housing 5 can be easily removed with one touch by turning the clamp ring 5G counterclockwise.
This makes it easy to remove seawater that has entered.

Overall, in this case, by dividing the housing and tongue 2 of the underwater shifter 1 into three parts: the battery housing 3, the motor housing 4, and the clutch housing 5, it is possible to prevent seawater from entering the entire housing 2 due to some malfunction during use. This is to prevent seawater from spreading into the motor housing 4, which is located in the center of the motor housing 4, and to completely prevent seawater from entering the motor housing 4, which is located in the center of the motor housing.

That is, the housing 2 has a motor housing 4 in the center.
is located and sandwiched between the battery housing 3 and the clutch housing 5 on the front and rear sides, so even if seawater should infiltrate either or both of the battery housing 3 and the clutch housing 5, the battery housing 3 and the clutch housing 5 will Since the clutch housings 5 are individually watertight, the seawater that has entered is prevented from entering other rooms. Further, in the individual housings, the first and second partition plates 18, 17, sealing means, and joining means of each housing cooperate to maintain watertightness in each room.

Further, when the underwater station g-1 itself needs to be disassembled or the battery 13 needs to be charged over the course of use, the interior of the housing 2 can be disassembled into three parts, making maintenance easier. Therefore, defects such as malfunctions can be easily discovered, and malfunctions that occur during diving can be prevented as much as possible, and safety is improved.

[Effects of the Invention] As detailed above, the first invention of the present application has the following features: (1) By providing the housing 2 with the partition plates 1B and 17, the interior of the housing z is divided into three compartments: battery chamber A and motor chamber B.
