Description

Intake apparatus of agricultural reservoir

The present invention relates to, for example, a water intake device installed in an agricultural reservoir for controlling water intake and water intake, and more particularly, a water intake tower, a slug gate, a spindle, a water intake door, an operation room, etc. It is easy to control the amount of water intake without the need to install and to prevent the troubles such as blockage or malfunction of intake pipe inlet by floating water, while maintaining the convenience of maintenance, minimizing the installation cost and ease of construction. It relates to a water intake device of the reservoir.

In recent years, the damages and damages to facilities due to abnormal climate and heavy rain due to global warming are increasing day by day, and it is difficult to cope with such concentrated rainfall due to the declining population and aging of rural areas.

In order to prevent such damage, there are also methods such as modernization and expansion of drainage facilities and strengthening the function and durability of repair facilities.However, by expanding the reservoir capacity of the reservoir, which is a water source, the rainwater is stored at the upstream water source to reduce the load downstream. Need to be prevented. Therefore, it is economical to use a reservoir for securing and controlling the above water.

The development projects related to these reservoirs are roughly divided into new projects to newly build reservoirs and reservoir renovation projects to prevent floods due to natural disasters and to secure additional water by reinforcing aging reservoirs.

On the other hand, the above-mentioned reservoir is an artificial water barrier in a place where river or valley water is easy to collect as one of the purposes of securing or preventing flooding, irrigation water, living water, agriculture and industrial water, and stored by blocking water flowing down from the upstream. When the reservoirs are classified by installation time, 16,250 reservoirs, which are more than 30 years old, account for 92%, of which 9,359 reservoirs were installed before 1945.

In addition, the current design standard of the above-mentioned agricultural reservoir intake facility requires that the dam height is 25m or more and the water intake tower is planned to be smaller than the water tower. The construction cost of the water tower is somewhat different depending on the size, but compared to the outline. It takes about 10 ~ 20 times excessively, and there are many difficulties in maintenance.

On the other hand, there are no excessive demands for the initial construction cost as mentioned above, but due to its structural characteristics, it is inevitably discharged in a situation where it is difficult to discharge the water supply in the following year due to frequent failures such as through gates, rollers, and spindles. After renovation work should be carried out, there is a problem that the water supply of the following year is insufficient, and emergency discharge is difficult in a short time during heavy rain forecast.

In addition, when the gate is opened and closed, various floats and sediments floating in the river face the water flow direction and are caught in the intake ports of the intake pipes formed at regular intervals with respect to the height direction of the embankment, causing malfunction or interruption of the through-gate. External factors such as hydraulic pressure, ice pressure, or forced operation of the handle may cause spindle deflection, door deformation, door failure, or even through-gate damage, resulting in loss of gate function. In addition, when water leakage occurs due to the failure of the gate pointed out at the time of securing the farm water supply, insufficient agricultural water is wasted, and in order to repair it, there is a need for workers to repair it by underwater work, which leads to high costs of human injury and maintenance. In particular, there is a problem that the location selection is limited because it must be installed on the rock to prevent leakage.

Therefore, if there is no functional problem, it is urgent to introduce a new water treatment facility for agricultural reservoirs in consideration of the advantages of the water intake tower and the communication.

Most of the agricultural reservoirs in Korea have been built for a long time, and the facilities have become obsolete.In addition, due to the high proportion of the intake tower type, which requires high installation and management costs, the initial installation cost is low, the maintenance is easy, and the maintenance cost is low. Installation is desperate.

Therefore, the present inventors supplement the shortcomings of the water intake tower and communication, which are the intake facilities of the agricultural reservoir currently used in Korea, and cause the failures such as clogging or malfunction of the water intake pipe due to suspended substances and sediment when securing water and adjusting the intake water. As a result of diligent efforts to develop a water intake apparatus for excluding, as a result, a water intake apparatus using a siphon method due to a level difference is created, and a large amount of water intake is not blocked by a floating material according to the water level set when the intake apparatus is operated. It was confirmed that it was possible.

After all, the main object of the present invention is to provide a water intake device for agricultural reservoirs that can simultaneously satisfy the security and control of agricultural water and control the amount of water intake, the water intake device is a conventional water reservoir intake tower, through-gate, water intake door It is achieved by installing a water inlet pipe along the inner bottom of the abdominal pain to the abdominal pain pit and installing a distillation valve to determine the water intake at the discharge part of the intake pipe.

Another object of the present invention is to provide an agricultural reservoir that can satisfy the convenience of maintenance and minimization of new installation or renovation cost while eliminating the cause of failure of the gate due to blockage or malfunction of the intake pipe due to various floats and external factors. A water intake device is provided, and this water intake device is achieved by airtightly coupling a water intake pipe that discharges and discharges water by siphoning the intake port of the water intake pipe so as to be detachable.

Still other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

According to the water intake device of the agricultural reservoir according to the present invention for achieving the above objects, the suction inlet along the slope of the dike and the abdominal pain penetrating in the up and down direction of the dike at regular intervals with respect to the height direction of the dike In the water intake apparatus which adjusts the amount of water by arranging a plurality of intake pipes and a plurality of step intake pipes which are bent vertically downward toward the water surface and suck and discharge water in a siphon manner due to a pressure difference under the water surface.

According to the agricultural water intake device of the present invention, because only the water intake pipe is installed in the reservoir, water leakage and failure factors are eliminated, which greatly reduces life-saving and maintenance costs, and also blocks water intake pipes caused by various floats. In addition to preventing malfunctions, the same size due to the siphon method allows more water to be taken in. In case of low water discharge due to heavy rain forecast, discharge is performed in less time than the existing water intake facilities. In addition, since there is no water gate facility, it does not require high water tightness and precision, so it is possible to newly or renovated at low cost without being restricted when selecting the installation location.The intake pipes are joined to the intake pipe by stage by flange, rubber packing and fastening bolt. Therefore, the replacement of the water intake pipe quickly It has a good effect.

First to fourth water supply valves 30, 32, 34, and 36 installed at discharge ports of the first and fourth water supply valves 30, 32, 34, and 36, respectively, to adjust the amount of intake to the sump 60 according to the water level of the reservoir. First to fourth emergency valves 40, 42, 44, 46 installed in the first to fourth step intake pipes 20, 22, 24, and 26 to prevent freezing and emergency water discharge, and the first Installed in the stepped intake pipe 20 to the check valve 50 to maintain a level line for interlocking the water level in the water intake pipe (20, 22, 24, 26) of the first to fourth step and the water level of the reservoir In the figure, reference numeral 72 in the drawing is a maintenance tool that can enter and exit the sump well 60 to operate the valves, and 74 is a ladder installed in the sump well 60.

Meanwhile, as shown in FIG. 4, the tightly coupled portion 28 includes the suction ports of the first to fourth stepped water intake pipes 20, 22, 24, and 26, and the first to fourth water intake curved pipes 10 ˜ opposite thereto. The first to fourth water intake curved pipes 10 to 1 through the ice pressure interposed between the pair of flanges 28a and 28b and the pair of flanges 28a and 28b respectively formed at the discharge ports of 13. The rubber packing 28c which prevents the bending and detachment of the 13 and maintains the watertightness, and the first to fourth water intake pipes 10 to the first to fourth water intake pipes 20, 22, 24, and 26. 13) is composed of a plurality of fastening bolts (28d) for fastening a pair of flanges (28a, 28b) to be removable.

The water intake device of the agricultural reservoir according to the present invention made as described above will be described in more detail with reference to FIGS. 1 to 4.

First, the first to the fourth is located in the toe of the abdominal pain 70 to discharge the water in the state that the water level of the reservoir maintains the full water level is installed in the first to fourth stage water intake pipe (20, 22, 24, 26) When a desired water supply valve, for example, the first water supply valve 30 is opened among the water supply valves 30, 32, 34, and 36, a pair of flanges 28a are provided at the inlet of the first stage water intake pipe 20. The suction port 14 of the first intake pipe 10 which is hermetically coupled by a tightly coupled portion 28 composed of a 28b and a rubber packing 28c and a fastening bolt 28d to face the water surface of the reservoir It is sucked through the siphon method, in which the suspended matter floating on the water surface of the reservoir and sediment on the surface is prevented from entering the screen 15 installed in the inlet 14 of the first intake pipe (10). Here, the first to fourth water supply valve (30, 32, 34, 36) for controlling the flow of the fluid is opened or closed by using a manual valve that can be opened and closed by the manager directly operating the handle or by the operation of the switch Electric valves can also be used.

Subsequently, the water introduced into the siphon method is collected through the discharge port of the check valve 50 and the first stage water intake pipe 20 which will be described in detail later, and then the waterproof passage 62 and Branching into the water main lines 64 and 66 proceeds withdrawal of water. Here, the first to fourth water intake pipes 20, 22, 24 and 26 and the first to fourth intake curved pipes 10 to 13 are flanges 28a of the tightly coupled portion 28 as shown in FIG. 28b) is fastened by a fastening bolt 28d and a rubber packing 28c for watertightness is interposed between the pair of flanges to absorb fluidity due to ice pressure, and as a result, the first to fourth water intake pipes ( 10-13) there is no failure factor such as bending or detachment, there is an advantage that it is easy to replace, especially in the aging of the intake pipes.

Subsequently, as the water intake proceeds through the first intake curved pipe 10 and the first stage intake pipe 20 as described above, the water level of the reservoir that maintains the full water level is gradually lowered, and the water level lowered as described above is the first. The moment away from the inlet 14 of the intake pipe 10, that is, the intake port 14 of the first intake pipe 10 through the interstitial first intake pipe 10 and the first step intake pipe 20 through Intake is stopped.

On the other hand, in the same manner as described above, if all of the manual or electric second to fourth water supply valve 32, 34, 36 installed in the second to fourth water intake pipe (22, 24, 26) In parallel with the intake of water through the second intake curved pipe 11 and the second intake pipe 22, the third and fourth intake curved pipes 12 and 13 and the third and fourth intake pipes 24 ( 26) With the simultaneous withdrawal of water, the water is collected into the sump 60 according to the water level of the reservoir, so that the water can be collected on the surface of the water. In addition, when the water intake proceeds at the same time, the water level of the reservoir is also rapidly lowered, whereby the second intake curved pipe 11 and the third intake curved pipe installed on the slope at regular intervals with respect to the height direction of the embankment 80. (12) and the suction ports 14 of the fourth water intake pipe 13 are sequentially released from the surface of the water and the water intake of the water is stopped.

Here, the air vents 16 protruding from the curved portions of the first to fourth intake pipes 10 to 13 are respectively remaining in the intake pipes 20, 22, 24, and 26 of the first to fourth stages when low water is sucked in. It is to smooth the flow of water by automatically exhausting the existing air. That is, the water is discharged through the first to fourth water intake curved pipes 10 to 13 and the first to fourth stepped water intake pipes 20, 22, 24, and 26 by the level difference, and the water is in progress. If air remains in the water intake pipes and the water intake pipes, the water does not flow smoothly regardless of the water level difference, thus preventing the function of the water intake facility.

Therefore, in order to smoothly flow the water by automatically exhausting the residual air in the intake pipe and the intake pipes as shown in FIG. 4 at the curved portions of the first to fourth intake pipes 10 to 13 described above. It is desirable to form the same air vents 16.

In addition, the check valve 50 installed in the above-described first level intake pipe 20 having the level of the smooth water level has a water level in the reservoir and the water level in the first to fourth level intake pipes 20, 22, 24, and 26. This is to intake water in conjunction with the same water level.

On the other hand, on the other hand, freeze protection of the first to fourth stage water intake pipes 20, 22, 24, and 26 and maintenance of the manual or electric first to fourth water supply valves 30, 32, 34, 36 are performed. In order to close the first to fourth emergency valves (40, 42, 44, 46) and the discharge portion of the water intake pipe (20, 22, 24, 26) of the first to fourth stages, that is located in the distal part of the abdominal pain 70 By opening the first to fourth water supply valve (30, 32, 34, 36) installed in the water, the water in the intake pipes can be drained to prevent freezing, the first to fourth water supply valve (30, 32, 34, 36) can also be maintained.

On the other hand, as a comparative example, in the conventional technique, that is, when water is discharged in a low water amount, water is discharged by an orifice method, and various floats and sediments in the surface of the reservoir are caught in the intake pipe, causing malfunction of the through gate. And unlike causing an operation stop, it can be seen that the present invention proceeds to take in the siphon method by installing a simple curved pipe at the inlet of the intake pipe.

As a result, according to the present invention, there is no water intake tower, through-gate, intake door, spindle, operating room, etc., which is a reservoir intake facility, so there is almost no failure factor, so maintenance is easy, and new installation and renovation costs are minimized. There is an advantage.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the present invention may be variously modified and implemented by those skilled in the art.

Such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments should fall within the appended claims of the present invention.
