Field of the Invention [0001] The present invention relates to an openable and closable hydrological apparatus, which is installed in a drainage passage of a cropland or the like to control the water level by controlling the drainage or control the moving direction of the drainage water,

By detecting and checking the water level of the accumulation point in real time and by automatically opening and closing the water gate automatically so that water can be automatically discharged, the opening and closing water can be operated quickly so that the possibility of flooding is minimized , The opening and closing gate can be manually elevated by a separate electric driving device, manually switchable in case of emergency, so that the opening and closing door can be operated freely according to the situation, and the foreign matter in the water can be opened and closed, It is a technology that is interposed between door frames so as to minimize the phenomenon of obstructing the opening and closing of the opening and closing doors and deteriorating the blocking effect.

Generally, drainage points for drainage of water in the drainage point are formed in the drainage points of farmland or reservoir according to the situation, and openable and closable drainage holes are provided in the drainage port to control opening / closing of drainage ports.

When the opening and closing gate of the opening gate closes the drainage hole and blocks the passage of water, when the water level in the drainage point rises to an appropriate level or higher due to rainfall or the like, the opening and closing gate is rotated or raised. So as to be drained.

However, in the case of agricultural land, the judgment on the rise time of the opening and closing water due to the rise of the water level was made by the operator visually confirming the water level and the water level in the water resistance point of the worker manually.

As the water level rises and the operation time of the opening and closing water is judged in the manual manner, it is highly likely that the operator will miss the opening time of the opening and closing door, that is, the time of the drainage due to the sudden increase in the water level due to heavy rain, There is a great problem in the possibility of flooding.

In addition, among the conventional openable and closable hydrological apparatuses, the up-and-down lifting and opening structure is such that foreign matter such as branches or trash present in the water during the lifting and lowering of the opening and closing water is interposed between the opening and closing gate and the watertight frame, Often occur.

In addition, since the opening and closing type hydrangea apparatus installed in the existing agricultural land is raised and lowered by using the separate passive type gate opening and closing gate, rapid drainage due to a sudden rise of the water level is required.

The male door frame 10 is installed in a drain port 70 formed at one side of the accumulation point 60 such as a river or a drainage path and serves as a supporting frame for the opening and closing gate 20 to be described later. And has a bar shape having a vertical direction as a whole, and is fixedly installed so as to face each other on the right and left inner side surfaces of the drain hole (70).

In this state, the upper and lower ends of the male and female doors 10 and 10 are connected to each other in a transverse direction, and thus have a generally rectangular shape.

At this time, a guide rail 11 for coupling with the opening / closing gate 20, which will be described later, is formed along the entire upper and lower longitudinal direction in the form of a straight rail groove.

For reference, the shape of the male housing frame 10 is not limited to the drawings, but can be modified into various forms as long as it can serve as a support for the opening and closing gate 20 and a vertical lift guide.

The gate frame (10) is provided with an opening / closing gate (20).

The opening and closing gate 20 functions to control whether or not the drainage opening is substantially opened and closed. The opening and closing gate 20 is located in a form of a plate as a whole and is positioned between the openings 10 and blocking the corresponding point.

At this time, since the right and left side edges of the opening and closing gate 20 are installed in the guide rail 11 of the positive water door frame 10, they can be lifted up and down along the forming path of the guide rail 11 .

For example, the size of the opening / closing gate 20 is not limited to the drawings, but may be variously modified depending on the area and shape of a drainage port of the drainage point 60 to be installed.

In this state, the foreign matter blocking member 30 is connected to the opening / closing gate 20.

The foreign substance blocking member 30 is for preventing a phenomenon that a foreign substance such as a branch present in the water is inserted between the opening / closing gate 20 and the guide rail 11, And is formed in the form of a sheet material of a soft material such as rubber as a whole and is located near the left and right edges of the front side of the opening /

In this state, each of the foreign substance blocking members 30 is fixedly coupled to the front side edge of the opening / closing gate 20 while the other side is connected to the front side edge of the opening / closing gate 20 and the guide rail 11, And is elevated and lowered together with the opening / closing gate 20 when the opening / closing gate 20 is raised / lowered in this state.

The foreign matter blocking member 30 is kept in a state of blocking the gap between the both sides of the left and right sides of the opening and closing gate 20 and the gap 31 between the front side of both the guide rails at all times, So that the phenomenon of being caught between the rails 11 is prevented.

In this state, the opening / closing gate (40) is connected to the opening / closing gate (20).

The water gate opening / closing door 40 functions to automatically or manually raise and lower the opening and closing gate 20 while providing a driving force necessary for lifting and lowering the opening and closing gate 20, and the driving case 41, the rotary member 43, A bar 44, a manual rotation lever 46, and a drive motor 48.

The driving case 41 serves as a supporting member for mounting the recove bar 44 and the rotating member 43 described later and for raising and lowering the recove bar 44. The driving case 41 is formed on the upper end of the worm wheel 10 And is placed on the mounting plate 80.

In this state, a rotary member 43 of the same shape as a pinion gear is installed inside the drive case 41 so as to be rotatable through the rotary shaft 42.

The rotary member 43 is for lifting and lowering the rak bar 44 to be described later to thereby raise and lower the opening and closing gate 20 through the lever bar 44. [

In this state, the rak bar 44 is installed in the drive case 41. The rak bar 44 is vertically lifted and lowered by the rotational force of the rotary member 43 and finally lifts the opening and closing water gate 20 A bar shape having an overall upper and lower longitudinal direction, and an engaging member 45 arranged on the front or rear side of the upper and lower sides.

The recove bar 44 passes through the drive case 41 and then passes through the installation plate 80 at the same time and its lower end is connected to the midpoint of the upper end of the opening and closing gate 20, The engaging member 45 located at a position within the driving case 41 is installed in the driving case 41 with the rotating member 43 engaged.

With this structure, the take-up bar 44 has a structure in which the take-up shaft 45 is lifted up and down in the vertical direction by the engagement between the rotation member 43 and the engagement member 45 when the rotation member 43 rotates. And the opening / closing gate 20 connected to the opening / closing gate 20 is vertically moved up and down.

In this state, a manual rotation lever 46 is provided on the rotation shaft 42 in the drive case 41. The manual rotation lever 46 is not in a state in which the rotation axis is automatically rotated through the drive motor 48, And is used when the operator directly rotates the rotary member 43 to manually raise and lower the rak bar 44 and the opening and closing gate 20. It is formed in a general lever shape and has one end portion at the end of the case inside rotary shaft 42 When the manual rotation lever 46 is rotated from the outside in accordance with the connection, the rotary member 43 rotates and thereby the lever bar 44 and the opening and closing gate 20 are operated.

At this time, the rotating shaft 42 is projected to the outside at a position opposite to the side of the drive case 41 to which the manual rotation lever 46 is connected. In this state, a driving motor 48 And a first power transmitting member 47 for connecting and disconnecting the first power transmitting member 47 and the second power transmitting member 47. [

In this state, a drive motor 48 is provided on the mounting plate 80.

The driving motor 48 serves as a driving source for actuating the rotary member 43 and the rak bar 44 by using a separate electric motor so that the opening and closing gate 20 can be raised and lowered. 80, the motor shaft 49 is positioned so as to face the first power transmitting member 47 in the same line.

The second power transmitting member 50 for connecting and disconnecting the first power transmitting member 47 is provided on the motor shaft 49 of the driving motor 48. The first power transmitting member 47 and the second power transmitting member 50 Since the second power transmitting member 50 has a mutually male and female interlocking structure, the rotational force of the driving motor is transmitted to the second power transmitting member 50 and the first power transmitting member 47 When the first power transmitting member 47 and the second power transmitting member 50 are separated from each other, power transmission between the first power transmitting member 47 and the second power transmitting member 50 is interrupted.

In this state, the water level sensor 51 is installed in the water resistance point 60.

The water level detection sensor 51 senses the water level of the water in the accumulation point 60 and senses the water level when the water level is out of the normal level so that the drive motor 48 is operated through the control part 52 to be described later, A sensor used for sensing the level of water is used and a part of the sensor is electrically connected to the control unit 52 to be described later in a state where the sensor is contained in the water in the accumulation point 60 Respectively.

The control unit 52 connected to the level sensor 51 is responsible for determining and controlling whether the drive motor 48 is operated according to a level abnormality signal transmitted through the level sensor 51 And is installed on the ground around the accumulation point 60. [0033]

The controller 52 is electrically connected to the level sensor 51 and the driving motor 48 and stores the appropriate level range data in the accumulation point 60.

Accordingly, when the level signal sensed by the water level sensor 51 is out of the corresponding data, the control unit immediately gives an operation signal to the drive motor 48, and the opening / closing gate 20 is automatically raised and lowered .

Hereinafter, the operation of the present invention with such a configuration will be described.

In the state in which the opening / closing gate 20 is lowered and the space between the left and right male door frames 10 is closed, water in the housing resin point 60 can not pass through the drain hole.

At this time, the foreign substances existing in the water are blocked by the foreign substance blocking member 30 and can not flow into the gaps between the side edges of the opening / closing gate 20 and the guide rails 11 of the gate frame 10, The possibility that the opening / closing gate 20 is disturbed by foreign matter is minimized.

In this state, the water level in the accumulation point 60 rises due to the rainfall and exceeds a proper level, and the water level sensor 51 senses this and sends the corresponding signal to the control unit 52, The drive motor 48 is actuated as the drive motor 52 immediately sends an operation signal to the drive motor 48.

As the driving motor 48 is operated as described above, the rotary shaft 42 and the rotary member 43 connected to the rotary shaft 42 and the rotary member 43 are rotated. As the rotary member 43 rotates, the recarking bar 44 linearly moves upward, The drainage port 20 is elevated and eventually the space between the positive and negative door frames 10, that is, the drainage port 70, the drainage of the water in the accumulation point 60 is achieved.

As the water level in the accumulation point 60 is sensed in real time by the water level sensor 51 and the water level is automatically exceeded when the water level exceeds the appropriate water level, rapid response can be achieved according to the water level change. Is minimized.

When the water level in the accumulation point 60 drops to an appropriate level in the course of draining water, the water level sensor 51 sends the corresponding signal to the controller 52. As a result, the driving motor 48 rotates in the reverse direction The opening / closing gate 20 is lowered to shut off the drain port, so that drainage is no longer performed.

If the water level sensor 51, the control unit 52 or the drive motor 48 is not operated normally due to an electrical failure, the operator manually rotates the manual rotation lever 46 to open / close the water gate 20 Since it can be manually raised or lowered, the opening and closing operation can be performed manually or automatically depending on the situation, thereby improving the situation coping ability.
