Description

Technical Field

[0001] This utility model belongs to the field of gate technology, and relates to gate control devices, and more particularly to a gate control system based on ecological balance. Background Technology

[0002] A sluice gate is a common hydraulic engineering facility used to control water flow and prevent flooding. Its operating principle can be simply summarized as opening and closing control and flow regulation. In automated sluice gate control, remote operation and real-time monitoring of the sluice gate can be achieved through the use of automation technology.

[0003] The history of gate automation control can be traced back to the 1970s. At that time, with the development of electronic and computer technologies, automation control was gradually applied to gate control in water conservancy projects. The introduction of automation control technology improved the accuracy and efficiency of gate operation and reduced the burden of manual operation. Simultaneously, centralized control and management of multiple gates was achieved through remote monitoring and scheduling systems.

[0004] Rivers and lagoons flowing into the sea are affected by the ebb and flow of tides. In order to protect the organisms and residents inside the rivers and lagoons from the effects of excessive tides, gates are usually built to regulate the water level of the rivers or lagoons and prevent excessive tides from entering.

[0005] However, constructing sluice gates to regulate water levels requires frequent opening and closing of the gates according to the tide level, which requires a large investment of manpower and physical resources for maintenance. On the other hand, conventional sluice gates are usually kept open or closed, or fully opened when the water level is high, which leads to unstable river water levels and severe scouring of the area near the sluice gates under the action of large flow, which is not conducive to maintaining ecological balance.

[0029] Embodiment 1

[0030] The utility model provides a gate control system based on ecological balance, see Figure 1 , including the concrete foundation structure 10 set between the river bank 11.

[0031] The concrete foundation structure 10 coincides with the bottom surface of the river, to solve the problem that the riverbed is scoured under the action of flow rate, at the same time reduce the silt in the upstream into the downstream and cause siltation, solve the ecological problem that the larger riverbed difference is formed in the local area, is not favorable to the fish swimming.

[0032] In addition, the concrete foundation structure 10 has a weir 12 with a height lower than that of the river bank 11 on both sides of the upper surface of the concrete foundation structure 10, and a notch 13 of a predetermined width is formed in the middle of the weir 12.

[0033] A plurality of support frames 21 are vertically installed in the concrete foundation structure 10 between the weirs 12 at uniform intervals, and a gate 25 is installed between the support frames 21. The weir 12 and the gate 25 store river water, thereby ensuring a certain water depth in the upstream and reserving a certain amount of fresh water. When the water level exceeds a predetermined height of the weir 12, the water is discharged to the downstream through the notch 13 in the weir 12.

[0034] Referring to Figure 2 , the overall structure further includes an inclined support 30 for firmly supporting the support frame 21 of the gate operating device 20, a water level sensing device 40 formed at the rear of the support frame 21 to sense a water level, and a control box 50. The control box 50 is a control device for controlling the gate operating device 20 in conjunction with a water level detection signal sensed by the water level sensing device 40.

[0035] The concrete foundation structure 10 coincides with the river bottom between the river bank 11, and the weir 12 has a height slightly lower than that of the river bank 11. Therefore, the notch 13 is formed to coincide with the base water level of the river, i.e., the highest fresh water level set in the present embodiment. Preferably, the width of the notch 13 can be 1 / 4 to 1 / 3 of the width of the weir 12, and the depth can be 10 to 15 cm.

[0036] Referring to Figure 1 and Figure 3 , an upper plate 22 is installed on the upper portion of the support frame 21, and a safety handrail 21a and a ladder (not shown) are installed on the outer periphery of the upper plate 22, thereby preventing falls. In addition, a ladder handrail 21b is provided on one side of the support frame 21 to perform maintenance when the gate operating device 20 malfunctions.

[0037] A U-shaped guide rail 23 is provided on the inner surface of the support frame 21, and the gate 25 is inserted into the U-shaped guide rail 23 to perform a lower elevation. A protrusion 24 is provided on the bottom surface of the guide rail 23 to prevent fine particulate silt from clogging the guide rail; the upper surface of the protrusion 24 is slightly inclined, and the bottom of the gate 25 is also slightly inclined and fitted to the protrusion 24, so that the gate 25 and the protrusion 24 are closely coupled.

[0038] A support 25a is provided at the center of the top of the floodgate 25 and is fixed by a bolt to the connecting rod 28 of the cylinder 27. The cylinder 27 is fixed to the upper portion of the upper plate 22 to move the floodgate 25 upward. The inclined support 30 is formed on the front surface of the support frame 21 so that the support frame 21 can withstand water pressure, and one end thereof is fixed to the upper portion of the support frame 21 by welding or a bolt, and the other end is fixed to the bottom surface of the concrete foundation structure 10.

[0039] As shown in Figure 2 , the water level sensing device 40 measures the water level of the river with respect to the concrete foundation structure 10 on the rear surface of the support frame 21, i.e., the side of the riverbed, transmits a water level detection signal to the control box 50, and controls the opening and closing of the floodgate 25 through a program.

[0040] Referring to Figure 4 , the water level sensing device 40 includes a main body 41 having a hollow pipe shape, and the main body 41 has an inlet hole 41a to allow water to flow into the main body 41. A sensor sensing unit 42 is provided at the upper portion of the main body 41, a circular guide shaft 43 is installed on the bottom surface of the sensor sensing device 42 in the vertical direction, a float 45 is freely coupled to the outer circumference of the circular guide shaft 43 according to the water level, and floats up and down according to the water level.

[0041] A sensor 44 is arranged on the outer circumference of the circular guide shaft 43 in a predetermined interval in the longitudinal direction, and the sensor 44 communicates with a magnet 46 in the float 45, when the water level reaches a set water level, the magnet 46 transmits a signal to the sensor 44, the sensor 44 feeds back the signal to the sensor sensing device 42, the sensing unit further transmits the signal to the control box 50 of the riverbank 11, and then controls the opening and closing of the floodgate 25. A stopper 47 made of a rubber ring is provided on the bottom surface of the guide shaft 43 so that the float 45 has a minimum drop height.

[0042] The control box 50 can individually or simultaneously operate a plurality of floodgates 25 according to the detection results of the water level sensing device 40. For example, when the water level gradually rises, a certain floodgate 25 can be individually controlled; when the water level rapidly rises due to rainfall, all floodgates 25 can be controlled to be opened. For example, the sensors 44 are arranged at intervals of 10 cm, with the water level of the slot 13 as a reference, and the floodgates 25 are opened by 10 cm under the control of the control box 50 every time the water level increases by 10 cm, which is advantageous in maintaining the water level.

[0043] As mentioned above, in normal circumstances, the gate control system based on ecological balance keeps the gate 25 closed, i.e. the lower end of the gate 25 is tightly connected with the protrusion 24 of the concrete foundation structure 10. When the water level rises by less than 10 cm relative to the water level of the slot 13, the upstream of the barrage 12 can always maintain a certain water level and store a certain amount of fresh water. Conversely, in the rainy season, due to the increase of short duration runoff, when the inflow of the river increases due to summer or local heavy rain, when the water level rises by more than 10 cm relative to the water level of the slot 13, the gate 25 will be opened according to the system setting, one or more; when the water level is higher than the reference water level 1 m, all the gates 25 are fully opened to avoid the river bank 11 being flooded.

[0044] When the reference water level after the flood drops to 0.3 m, the gates 25 are automatically closed one by one from both ends to the center, and the fresh water is gradually stored in the upstream of the barrage 12.

[0045] Since the gates are automatically controlled to gradually open, the erosion of the riverbed by the water flow can be reduced, the difference between the riverbed before and after the flood can be small, and the fish swimming is not affected. The control box 50 can automatically adjust the water level, and if there is a problem in the automatic adjustment of the water level, the control box 50 can be manually switched to allow the operator to arbitrarily operate the gate 25.

[0046] The gate 25 is opened and closed by the pressure pump unit 26 installed on the upper plate 22, of course, the opening and closing of the gate 25 is not limited to being achieved by hydraulic pressure or air pressure.

[0047] The above describes the utility model and its embodiments in a schematic manner, which is not restrictive, and the embodiments shown in the drawings are only one of the embodiments of the utility model, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments can be designed without creativity, which should all belong to the protection scope of the utility model.
