The upper part of the sensor (200) is connected with a data transmission cable (210) to transmit data.
A flange portion is formed on the upper surface of the lower casing (100) to be coupled to an upper housing (400) to be described later. The flange part comprises a water sealing cover (310) with a through hole (130) through which the sensor (200) penetrates; a flange (300) formed to protrude from the watertight lid (310) and coupled to the first upper surface (110a) by bolts; and a coupling groove (320) formed to be recessed at an outer side of the watertight lid (310).
Wherein the first upper face (110a) and the flange (300) comprise a plurality of recesses for bolt mounting at mutually corresponding positions.
Furthermore, a sealing material (140) is interposed between the first upper surface (110a) and the flange (300) so as to fasten the joined portion when the joint is attached by bolts or the like. The sealing material (140) may be a rubber sealing material or the like, and it is recommended to install at least one.
The upper portion of the flange (300) is installed with a watertight cover (310) inserted into the upper cabinet (400), and the watertight cover (310) includes a lever (600) installed with the upper cabinet (400) and a coupling groove (320) for contact and separation.
Next, the upper housing (400) has a through hole on a second upper surface (410a) and a second lower surface (410b), which is penetrated by the sensor (200), and includes a second space portion for receiving the water sealing cover (310), and a connection portion (420) for fixing the data transmission cable (210).
The second space portion is inserted with a sealing material, so that the sensor (200) can be prevented from being damaged.
In addition, both sides of the upper case (400) each include a pair of lever (600) hinge-coupled, and a space in which the lever (600) is rotatable is formed.
In addition, the data transmission cable passes through the upper portion of the sensor (200) in the through hole (130) of the second upper face (410a), and a spacer (430) and a connection portion (420) are provided between the through hole (130) and the data transmission cable (210), so that the data transmission cable (210) can be fixed and the entry of foreign materials and water can be prevented.

Thereafter, in order to maintain the sensor (200), the worker removes the sensor from the lower housing (100), and the shield door (500) closes the through hole (130) of the first upper surface (110a) by the elastic force of the spring hinge (510).
The sensor (200) is separated from the lower casing (100), and simultaneously, seawater enters through the through hole (130) of the first lower surface (110b), the shielding door (500) blocks the through hole (130) of the first lower surface (110b) to prevent the seawater from entering the inside, therefore, the seawater cannot enter the ship, the higher the pressure of the external seawater is, the tighter the shielding door (500) on the flange is, and the tighter the shielding door (500) is.
Further, when the sensor (200) is mounted, if an opening button (520) mounted inside the screen door is pressed while the sensor (200) is inserted, the screen door (500) can be opened without force, and the sensor (200) is mounted.
Similarly, even if the sensor (200) is detached from the lower surface of the hull, the shield door can prevent seawater from entering the hull, so that maintenance operations such as periodic inspection, maintenance and replacement of the sensor (200) can be easily performed even while the ship is underway.
Fig. 5 is an enlarged view of an upper housing of the apparatus for measuring a speed of a ship according to an embodiment of the present invention.
As shown in fig. 5, a pair of levers (600) are hinged to each other at both sides of the upper housing (400).
The control lever (600) includes a hinge portion (610) coupled to a hinge on the upper case (400), a handle portion (620) formed by extending one end of the hinge portion, and a fixing protrusion (630) formed by extending the other end of the hinge portion to be contacted with and separated from the coupling groove (320).
The hinge part (610) of the control lever forms a fixing hole (650) penetrated by a fixing pin (640) for fixing the control lever, and the control lever (600) rotates by taking the fixing pin (640) as an axis.
The fixing protrusion (630) is located at a position contacting the coupling groove (320), and when the lever is pulled, the fixing protrusion (630) is separated from the coupling groove (320), and the upper case (400) and the water sealing cover (310) can be separated.
Also, both sides of the lever handle (620) are provided with latch type coupling protrusions (660).
The lever hinge part (610) is provided with an insertion groove (670) into which a latch type coupling protrusion (660) can be inserted.
When the control lever (600) contacts the water sealing cover (310), the latch type coupling protrusion (660) is inserted into the latch insertion groove (670), thereby immobilizing the handle (620) of the control lever.
In addition, the handle (620) of the lever is pulled to separate the fixing protrusion (630) from the water sealing cover (310), and the latch type coupling protrusion (660) protrudes and fixes the handle (620) of the lever so that it cannot move.
Therefore, the upper case (400) and the water sealing cover (310) can be securely contacted and detached.
As described above, when the lever (600) is used, an operator can easily disassemble the upper case (400) and maintain the sensor without assembling bolts, thereby saving time and cost.
