In addition, although the said groove part 25 is extended in the up-down direction, it is not formed to the lower end of the driven part 23. FIG. The protruding portion 26 protrudes outward from the driven portion 23 and extends in the vertical direction. The protruding portion 26 is configured to correspond to a locking portion 39 of the operation transmitting portion 35 described later, and extends to a position where it contacts the locking portion 39. Further, as shown in FIG. 2, the protrusion 26 is disposed in the storage portion 10 formed on the inner surface of the casing middle portion 6b in a state where the manual operation portion 51 is interlocked with the electric operation portion 52. The shaft 21 cannot rotate in the direction opposite to the locking portion 39 (clockwise direction in FIG. 2).
The follower 23 has a magnet (not shown) inside, and the magnet can detect position information by a sensor.

The grip 30 has an insertion port 31 having a substantially cross shape in plan view formed so that the operation shaft 21 can be inserted therein, and four guide portions 32 having a substantially cross shape in plan view from the outer periphery toward the outside. So as to protrude.
For this reason, the guide part 32 can attach the holding | grip part 3 so that attachment or detachment is possible.

When the electric button is operated, a pinion gear is based on an electric signal from the base. 42 is rotated in a predetermined direction. The motor 41 can be rotated in both directions based on the electrical signal.

  The construction of the drain plug device of the present invention will be described below.

In the drain plug device of the present embodiment, the operation device 5 is assembled to the following state in the factory.
First, the lock mechanism 45 is attached to the casing lower part 6c. Next, the casing lower part 6c is attached to the casing middle part 6b from below. At this time, the rod portion 46 is inserted into a through-hole formed below the wall portion 9 that partitions the bypass 8 and the mechanism chamber 7, and an end portion is disposed in the mechanism chamber 7.
Next, the operating shaft 21 is disposed in the casing middle part 6b. At this time, the operating shaft 21 is inserted from the inside of the mechanism chamber 7 into the through-hole formed above the wall portion 9 with the grip portion 30 not attached, and its end portion is higher than the upper end of the casing middle portion 6b. Located in.
Here, packings are disposed in the through-holes formed above and below the wall portion 9, respectively, and each packing comes into contact with the rod portion 46 and the operation shaft 21 to be in a watertight state. Accordingly, the waste water flowing in the detour 8 does not flow into the mechanism chamber 7.
Next, the grip portion 30 is inserted through the operation shaft 21 and attached. The through hole formed above the wall portion 9 has substantially the same diameter as the outer diameter of the operation shaft 21 and is smaller in diameter than the grip portion 30, but in the present invention, the grip portion 30 is connected to the operation shaft 21. Therefore, it is possible to attach the grip portion 30 after the operation shaft 21 is arranged. Further, a substantially cross-shaped rib 22 is formed on the operation shaft 21, and an insertion port 31 having substantially the same shape is formed on the grip portion 30. Accordingly, when the grip portion 30 attached to the operation shaft 21 is rotated, the operation shaft 21 is also rotated.
Next, the operation transmitting unit 35 is attached so as to cover the driven unit 23. At this time, since the motion transmission unit 35 has a substantially semicircular shape in plan view, it can be easily attached without performing the operation of inserting the operation shaft 21. And the cover body 13 is attached with respect to the casing center part 6b using the screw which is not illustrated. At this time, since the motion transmission part 35 is clamped by the casing middle part 6b and the lid body 13, it can be displaced only in the vertical direction.
This completes the assembly of the operation device 5 in the factory.
Next, the casing upper part 6a is attached to the opening formed in the edge part of the tank body 1 in the field. And the casing middle part 6b is attached from the downward direction of the said casing upper part 6a, and the casing upper part 6a and the casing lower part 6c are connected with a C-shaped band.
Next, after fitting the button portion 20 to the operation shaft 21, an outer tube is attached to the pipe on the downstream side of the drain plug 2, the valve shaft 40 is fixed to the wire receiver 3, and the valve body 4 is attached to the valve shaft 40. By fitting, the construction of the drain plug device of the present embodiment is completed.

  Next, the operation of the drain plug device of this embodiment will be described.

First, the operation by the manual operation unit 51 will be described in detail.
As shown in FIG. 1, when the valve body 4 is in the lowered state and the drain port is closed, if the operation on the manual operation unit 51, that is, the button unit 20 is directly pushed, The button portion 20 is displaced downward and the operation shaft 21 is lowered. At this time, the inner wire slides toward the valve body 4 in the outer tube, and the valve body 4 rises by pushing up the valve body 4 from below. Further, as the operating shaft 21 is lowered, the rod portion 46 is pushed down, the lock mechanism 45 is activated, and the raised state of the valve body 4 is maintained.
At this time, as shown in FIG. 8, the motion transmitting unit 35 remains at the height position before the push operation is applied to the button unit 20, and only the button unit 20 and the driven unit 23 are lowered.

  When the push operation is further applied directly to the button portion 20 in the raised state of the valve body 4, the meshing of the gear in the lock mechanism 45 is released, so that the inner wire slides toward the operating device 5 side. As a result, the valve body 4 is lowered. Further, as the valve body 4 is lowered, the button portion 20 and the operation shaft 21 are raised and returned to their original positions.

  As described above, when the operation by the manual operation unit 51 is performed, all the members constituting the electric operation unit 52 including the operation transmission unit 35 do not operate at all.

Next, the operation by the electric operation unit 52 will be described in detail.
When the valve body 4 is in the lowered state and the drain outlet is closed, if an operation is applied to an electric button (not shown), the motor 41 is activated based on the electric signal, and the pinion gear 42 is rotated. As a result, the rack gear 36 is displaced downward, and the motion transmission unit 35 is lowered. At this time, as shown in FIG. 9, the contact portion 37 contacts the stepped portion 24, and the operation of the electric operation portion 52 is transmitted to the manual operation portion 51 by pushing down the driven portion 23 (operation shaft 21). Then, when the manual operation unit 51 is lowered, the valve body 4 is raised, and the raised state of the valve body 4 is held by the lock mechanism 45.
Thereafter, when it is detected by a sensor (not shown) that the operation shaft 21 has been lowered to a predetermined position, the motor 41 rotates in the reverse direction, and the motion transmission unit 35 returns to the original position. At this time, as shown in FIG. 8, the positional relationship between the members of the operating device 5 is exactly the same as when the valve body 4 is raised by the manual operation unit 51.

  When the operation is further applied to the electric button in the raised state of the valve body 4, the motor 41 is driven again, and the operation transmission unit 35 pushes down the operation shaft 21, thereby releasing the meshing of the gear in the lock mechanism 45. As a result, the valve body 4 is lowered. At this time, the positional relationship of each member of the operating device 5 is exactly the same as when the valve body 4 is lowered by the operation of the manual operation unit 51 as shown in FIG.

  As described above, in the present invention, the manual operation unit 51 has a structure interlocked with the operation of the electric operation unit 52. And when operation is added with respect to the electric operation part 52, every time the motor 41 is driven, the operation transmission part 35 returns to the original position shown in FIGS. Even when the operation is performed, the positional relationship between the members when the valve body 4 is raised or lowered is always in a predetermined arrangement. Accordingly, the manual operation unit 51 can be operated after the electric operation unit 52 is operated, and the electric operation unit 52 can be operated after the manual operation unit 51 is operated.

On the other hand, when the motor 41 is stopped while the operation transmission unit 35 is lowered as shown in FIG. 9 due to the biting of sand or dust or the sensor damage, the driven unit 23 and the operation transmission unit 35 interfere with each other. Therefore, the operation by the manual operation unit 51 cannot be performed. In this case, the manual operation unit 51 and the electric operation unit 52 can be unlocked by operating the release mechanism as follows.
First, in the state of FIG. 9, the button unit 20 is removed from the operation device 5. In addition, in the case of removal, it can also remove by inserting a stick | rod etc. in the clearance gap between the button part 20 and the casing 6 other than the method of making a suction cup adsorb | suck to the button part 20, and pulling up.
Next, the grip portion 30 attached to the operation shaft 21 is gripped, and the operation shaft 21 is rotated. At this time, as shown in FIG. 10B, the protrusion 26 gets over the locking portion 39 from the state of FIG. 10A, and the interlocking state of the manual operation unit 51 and the electric operation unit 52 is released. . That is, the step portion 24 is disposed immediately below the slit 38 and the groove portion 25 is disposed directly below the contact portion 37 by the rotation of the operation shaft 21, so that the driven portion 23 and the motion transmitting portion 35 are mutually connected. It is arranged at a position where it does not interfere. As a result, as shown in FIGS. 11 and 12, the operation shaft 21 can return to the original position, and thereafter, the valve body 4 can be lifted and lowered only by the manual operation portion 51. By rotating the operation shaft 21, the magnet disposed inside the operation shaft 21 is positioned outside the detection range of the sensor, and the electric operation unit 52 becomes inoperable.
Further, as shown in FIG. 10A, when the manual operation unit 51 is in an interlocking state with the electric operation unit 52, the protrusion 26 is disposed in the storage unit 10 and only in the direction of releasing the interlock. It can be rotated. Therefore, it is impossible for the operator to rotate the operation shaft 21 in the wrong direction. On the other hand, in a state where the interlocking of the manual operation unit 51 and the electric operation unit 52 is released, the protrusion 26 interferes with the abutting part 37 of the motion transmission unit 35, so that the interlocking release state shown in FIG. It cannot be rotated in the same direction. Therefore, the interlocking of the manual operation unit 51 and the electric operation unit 52 can be reliably released. Here, in a state where the interlocking between the manual operation unit 51 and the electric operation unit 52 is released, the manual operation unit 51 is interlocked with the electric operation unit 52 again by rotating the operation shaft 21 in the reverse direction (right rotation). It is possible. At this time, the protruding portion 26 gets over the locking portion 39 and is disposed in the storage portion 10, and the manual operation portion 51 is brought into the interlocked state again. That is, the release mechanism can be rotated only in the direction in which the manual operation unit 51 is interlocked with the electric operation unit 52 and the interlock is released. A rotation range regulating mechanism is provided so as to be rotatable only in the direction. That is, the rotation direction is regulated according to the release state, and the angle at which the rotation is possible during rotation is regulated. Therefore, it becomes possible to prevent failure of release and damage to the member due to rotation in the wrong direction or excessive rotation.

  In the drain plug device according to the present invention, the interlock release operation is easy, and when the electric operation unit 52 breaks down like the conventional drain plug device, the apron portion of the tank body 1 is removed and repaired. Work can be omitted. Therefore, even a general user can perform the unlocking operation.

  Note that the release of the connection between the manual operation unit 51 and the electric operation unit 52 is a temporary measure, and eventually the electric operation unit 52 needs to be replaced. Even in this case, if the grip portion 30 is detachable, the replacement work is facilitated. Further, when the manual operation unit 51 is clogged, the inside of the manual operation unit 51 can be cleaned by removing the button unit 20 and the grip unit 30.

  Further, in the drain plug device, a slight space is formed between the button portion 20 and the casing upper part 6a, and drainage may flow from the space, but the drained water that has flowed in passes through the casing upper part 6a. , It passes through the detour 8, passes through the outside of the lock mechanism 45, and is discharged downstream. That is, drainage does not flow into the mechanism chamber 7 due to the packing disposed on the wall portion 9. Therefore, it is possible to prevent the drain plug device from malfunctioning due to the inflow of drainage.

Although the drain plug device in the present invention is as described above, the present invention is not limited to the shape of the above embodiment, and various modifications can be made without departing from the scope of the invention. For example, in the above embodiment, the operation mechanism has the manual operation unit and the electric operation unit, but may have only two or more manual operation units. Moreover, you may have a total of three or more manual operation parts and electric operation parts.
In the above-described embodiment, the release mechanism is disposed in the manual operation unit. However, the release mechanism may be provided in a place different from the manual operation unit.
