Non-motorized automatic floodgate

The present invention relates to a non-powered automatic sluice gate, and more particularly, it does not require power to open and close the sluice gate, so that smooth opening and closing operation of the sluice gate is possible even in an emergency such as a power outage or failure, thereby ensuring operational reliability and safety. It is about non-motorized automatic floodgates.

In general, a sluice gate is a gate installed to block the flow of water or to control the flow rate, and is mainly installed in waterways such as rivers, rivers, reservoirs, and dams.

In the past, most of the sluice gates were manually opened and closed, but conventionally, sluice gates capable of automatically opening and closing are widely used.

For example, there is a vertical opening/closing type sluice gate having a structure that opens or closes a water channel by moving the sluice gate body formed in a plate shape up and down using a motor.

The conventional sluice gate requires a relatively large force to open and close, and various problems are exposed, such as overloading the motor due to resistance by various foreign substances.

On the side, a water outlet 34 through which the water filled in the accommodating space 31 can be discharged to the outside is formed.

An on/off valve 35 is further provided at the water outlet 34 . Rotate the opening/closing valve 35 to one side so that the water inside the receiving space 31 can be discharged to the outside through the water outlet 34, or rotate to the other side to the inside of the receiving high through the water outlet 34 of water can be prevented from being discharged to the outside.

The rotation control unit 40 closes the discharge port 11 when the water level of the beam 5 is less than the set reference water level, and opens the discharge port 11 when the water level of the beam 5 is above the set basic water level. Intermittent rotation of (30).

The rotation control unit 40 is configured to include a housing 410 , an elevating part 420 , a support link 430 , a lock link 440 , and an interference rod 450 .

The housing 410 is formed in a cylindrical shape with an open top and a bottom, a hollow part is formed inside so that the sub-sphere 421 can ascend and descend, and one side of the outer circumferential surface is fixed to the foreign substance blocking part 20 . On both sides of the housing 410 opposite to each other, a support link 430 to be described later can pass therethrough, and a flow slot 411 through which the support link 430 can flow up and down a predetermined distance extends vertically.

The elevating part 420 includes a floating body 421 , a height adjustment rod 422 , a nut member 423 , and a support piece 424 .

The floating body 421 has buoyancy and is inserted into the housing 410 and elevates inside the housing 410 according to the water level of the beam 5 .

The height adjustment rod 422 has a screw portion formed on its outer circumferential surface, the upper end is fixed to the lower end of the subspherical body 421 , and extends downward a predetermined length along the longitudinal direction of the housing 410 .

The nut member 423 is for adjusting the height of the subspherical body 421 with respect to the housing 410 by rotating the height adjusting rod 422, and is on the support piece 424 disposed below the subspherical body 421. is fixed

The support piece 424 is disposed at the lower portion of the elevating part 420 inside the housing 410 , and the nut member 423 is fixed to one side.

The support link 430 is configured as a pair, and each support link 430 has one end rotatably installed at one end and the other end of the support piece 424, and the other end is the frame portion 10. is rotatably installed on both sidewalls 120 of the . The other end of the support link 430 extends to a length that can be exposed to the outside of both side wall portions 120, and when the lifting port 420 is higher than the set reference water level, the other end is rotated downward and a lock link to be described later. 440 is interfered with at the end.

The lock link 440 is rotatably installed on the side wall part 120 of the frame part 10 corresponding to the other end of the support link 430, and the center of the length is rotatably installed, and the other end of the support link 430 is rotated downward. When it becomes, one end is interfered with the other end of the support link 430 and rotates downward, and the other end rotates upward. A hook is provided at the end of the lock link 440 to hang the interference rod 450 .

The interference rod 450 has one side fixed to the sluice body 30 , and the other side extends longer so that it can protrude more outward than the side wall part 120 of the frame part 10 . The interference rod 450 also has a function for intermittent rotation of the sluice body 30 together with the lock link 440, but when the upper side of the sluice gate body 30 is rotated below the frame part 10, the side wall part It also has a function of blocking the reverse rotation of the sluice gate body 30 from the outlet 11 while being caught by the 120 .

After the user rotates the height adjusting rod 422 to position the floating body 421 at a set height (reference water level), when the water level reaches the set height and the elevating port 420 rises, the elevating port 420 and As the connected support link 430 interferes with the end of the lock link 440, the lock link 440 is rotated, and in this process, the lock link 440 hung on the interference rod 450 is rotated upward to rotate the interference rod. As the locking state of 450 is released, the sluice gate body 30 is in a state in which it can be rotated. On the other hand, when the water level is lower than the set height and the elevating unit descends, the interference of the support link connected with the elevating unit to the end of the locking link is released, and the end side of the locking link on which the hook is formed is rotated downward and the sluice gate body returns to its original state. During the return, the interfering rod coupled to the sluice gate is engaged (locked) so that it is caught on the hook part of the locking link again, and the sluice gate closes the outlet until the water level reaches the set reference water level again.

Hereinafter, the operation of the non-motorized automatic sluice gate 1 according to the present invention having the configuration as described above will be described in more detail with reference to FIGS. 4 and 5 .

First, when the water level of the beam 5 is below the reference water level, the rotation of the sluice gate body 30 is blocked so that the water channel 6 can be maintained in a closed state through the rotation control unit 40 as shown in FIG. .

And, as shown in FIG. 5, the water level of the beam 5 reaches the inlet provided in the sluice body 30 or becomes higher than the inlet, so that the water overflows the sluice body 30 as shown in FIG. In this case, the water on the upstream side of the beam 5 flows through the inlet until the water level of the beam 5 becomes higher than the set reference water level (for example, a height higher than the upper end of the sluice body 30). ) continuously flows into the inside.

Thereafter, the water level of the beam 5 is higher than the reference water level, so that the elevating part 420 of the rotation interception unit 40 rises with the water level, and in this process, the interference rod 450 of the sluice gate body 30 locks the lock link. The lock state for 440 is released. At this time, less water is filled in the receiving space 31 inside the sluice body 30, and the upper weight of the sluice body 30 is smaller than the lower weight of the sluice gate body 30, so the difference between the upper and lower weights of the sluice gate body 30 If there is, the sluice gate body 30 is not rotated, and a considerable amount of water is filled in the receiving space 31 inside the sluice gate body 30 so that the lower weight of the sluice gate body 30 and the upper weight of the sluice gate body 30 are Only when the sluice gate body 30 is rotated in a similar state, that is, in a balanced state, the outlet 11 is opened.

When the sluice gate body 30 is rotated and the discharge port 11 is opened, the flow of water passing through the discharge port 11 and the water filled in the lower weight body 32 and the upper receiving space 31 are balanced. The sluice gate body 30 is in a state lying in the horizontal direction.

After that, when the water level of the beam 5 is lower than the sluice gate body 30 lying in the horizontal direction, the water filled in the receiving space 31 on the upper side of the sluice gate body 30 is discharged through the water outlet 34, and the receiving space When a significant amount of water in the part 31 is discharged, the lower side of the sluice body 30 becomes heavier than the upper side by the weight 32, and the sluice gate body 30 rotates back to its original position as shown in FIG. 11) is closed.

Then, when the sluice gate body 30 is completely rotated to its original position to close the discharge port 11 , the interference rod 450 provided in the sluice gate body 30 is again attached to the hook of the lock link 440 again. It is caught and locked, and the outlet 11 is maintained in a closed state until the water level of the beam 5 becomes higher than the set reference water level again.

On the other hand, if the opening/closing valve 35 provided in the sluice gate body 30 is opened, as described above, when the water level rises, the sluice gate body 30 rotates and the outlet 11 is opened, and when the water level goes down, the sluice gate body ( As the 30) returns to the original position, the state in which the outlet 11 is closed is repeated.

However, if the opening/closing valve 35 is closed, the water in the receiving space cannot be discharged after the receiving space is filled with water, so the water body continues to lie in the horizontal direction, so the water gate body 30 cannot return to its original position. , through which the discharge port 11 remains open.

That is, depending on whether the on-off valve 35 is opened or closed, the discharge port 11 may be opened or closed according to the water level, and the discharge port 11 may be continuously maintained in an open state.

On the other hand, the non-powered automatic sluice gate 1 according to the present invention has a structure in which the rotation control unit 40 is positioned on the upstream side of the beam 5 rather than the foreign material blocking unit 20, but differently from this, foreign substances Rotate the foreign material blocking unit 20 by changing the positions of the foreign material blocking unit 20 and the rotation stopping unit 40 to prevent the rotation control unit 40 from being able to operate stably due to interference or interference with the unit 40 Of course, it is possible to apply a structure arranged to be located on the upstream side of the beam than the intermittent part 40.

The non-motorized automatic sluice gate according to the present invention described above has been described with reference to the accompanying drawings, but this is only an example, and various modifications and equivalent other embodiments are possible by those skilled in the art. will understand
