Description

Technical Field

[0001] The invention relates to sediment separation equipment, in particular to a water waste separation device that prevents sediment deposition. Background Art

[0002] The irrigation canal system is mainly composed of fixed channels such as the headwater, trunk, branch, bucket, and farm. In actual operation, irrigation is mostly carried out by continuous irrigation of the trunk and branch, and rotation irrigation of the bucket and farm. During the non-irrigation period, a canal section with an open gate and a closed end will be formed at the front of the gate at the headwater or branch channel. At this time, the water flow movement structure in the canal section in front of the gate is complex, and the silt carried by the water flow is easy to accumulate here, causing blockage of the open channel section in front of the gate, resulting in poor opening of the gate or even damage. For larger objects such as branches, leaves, and weeds, there are mechanisms such as trash racks to intercept them, which can effectively reduce the impact of larger objects such as branches, leaves, and weeds on the gate. However, there is no effective interception mechanism for fine objects such as silt. Generally, high-pressure gas or water is sprayed at the gate to wash away the silt at the gate, thereby preventing the problem of silt accumulation. However, there are the following problems: during the high-pressure flushing process, some silt enters the gap between the gate and the ditch under the action of high-pressure water, causing blockage at the gate. At the same time, no matter which flushing method is used, there are blind spots in the flushing, which makes it impossible to completely clean up the deposited silt at the gate. The blockage problem still exists, making it difficult to open and close the gate and may even be damaged. Summary of the invention

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figure 1-3 As shown, a water-waste separation device for preventing sediment deposition comprises a fixed frame, a semicircular rubber airbag 7, a semi-arc-shaped sand separation column 10, a sand retaining plate 11, an air pump 13, a solar power supply system 1 and a control system.

[0029] The function of the fixed frame is to support the semicircular rubber airbag 7. For some places where the gate width is not large, a square frame can be used. The frame material can be corrosion-resistant, aging-resistant stainless steel or plastic. For some places where the gate width is large, the following structure can be used:

[0030] The fixed frame includes two columns 32, two fixing plates 34 and two pillars 33. The column 32 passes through the airbag spring 6 and is installed with the fixing plate 34 through a nut. The fixing plate 34 is provided with two sets of moving grooves 20. The pillar 33 is installed in the moving groove 20 through the pillar spring 15. The pillar is fixed with the gate plate pull rope 14 of the gate through the first pull rope 4 and the pulley 16. The above structure can form a strong support for the semicircular rubber airbag 7 to prevent deformation caused by excessive water pressure and reduced sealing. At the same time, when the semicircular rubber airbag 7 is deflated and retracted, the two pillars move to both sides under the action of the first pull rope 4 to prevent the gate from being blocked from discharging water.

[0031] One side of the fixed frame is fixed to the gate frame 3 of the gate, and the other side of the fixed frame is fixed to the edge of the semicircular rubber airbag 7 through the airbag spring 6. Under the elastic force of the airbag spring 6, the semicircular rubber airbag 7 is unfolded to seal the ditch 12 at the edge of the gate frame 3, so that the gate is in a sealed state. In this embodiment, the fixed frame is fixed to the gate frame 3. When the gate discharges water, the semicircular rubber airbag 7 is deflated. At the same time, under the joint action of the airbag spring 6 and the support spring 15, the semicircular rubber airbag 7 is retracted upward to prevent blocking the water discharge. This method can effectively reduce the power consumption when the gate is opened. Of course, the fixed frame can also be fixed to the gate plate of the gate, and it can rise and fall with the gate, but the power required is large. In order to prevent the airbag spring 6 from being wrapped by mud and sand, a protective cover 17 is provided on the airbag spring 6.

[0032] The structure of the semicircular rubber airbag is similar to the dam bag structure of the rubber dam, and is mainly used to seal the ditch 12 at the edge of the gate frame 3, so that the gate is in a sealed state, with one side tightly fixed to the fixed frame and the other side semicircular. A support frame can also be set inside it to make it more closely contact with the fixed frame. The two ends of the semi-arc sand column 10 are in close contact with the semi-arc rubber airbag 7 and the sand retaining plate 11 respectively. The function of the semi-arc sand column 10 is that when there is sediment deposition at the gate, the deposited sediment is deposited on both sides of the semi-arc sand column 10 under the action of gravity, effectively preventing a large amount of sediment from being deposited in the middle of the gate and blocking the gate. The sand retaining plate 11 has two functions: (1) preventing the sediment at the bottom of the water flow from moving with the water flow to block the gate; (2) setting obstacles at the gate to change the flow direction of the water flow, forming a water flow vortex, increasing the water flow speed and pressure, and then washing away the sediment in front of the gate to reduce deposition.

[0033] The semi-arc sand column 10 and the sand retaining plate 11 are fixedly arranged at the bottom of the ditch 12. Their shapes will affect the water flow velocity and have an impact on the water discharge of the gate, so their height and width need to be reasonably set.

[0034] The height of the semi-arc sand column 10 is 1 / 5-1 / 4 of the gate height, the height of the sand retaining plate 11 is 5-15cm higher than the height of the semi-arc sand column 10, and the length of the sand retaining plate 11 is 10-20cm shorter than the semicircular rubber airbag 7; In this embodiment, the height of the semi-arc sand column 10 is 1 / 5 of the gate height, the height of the sand retaining plate 11 is 10cm higher than the height of the semi-arc sand column 10, and the length of the sand retaining plate 11 is 10cm shorter than the semicircular rubber airbag 7. The above height and width will not have a significant impact on the water flow rate of the gate on the basis of sand separation and sand settling.

[0035] The main function of the air pump 13 is to inflate the semicircular rubber airbag 7. The air outlet of the air pump 13 is connected to the semicircular rubber airbag 7. The semicircular rubber airbag 7 is provided with an exhaust valve and a water inlet channel 9. The water inlet channel 9 passes through the semicircular rubber airbag 7 and is connected to the gate. The water inlet channel 9 is arranged at a position higher than the sand retaining plate 115-10cm, and 5cm is adopted in this embodiment;

[0036] The exhaust valve is connected with an exhaust hose 8, which is fixed on the surface of the semicircular rubber airbag 7, and the air outlet of the exhaust hose 8 is arranged at a position lower than the sand baffle 11. The exhaust valve generally adopts a solenoid valve.

[0037] The purpose of the water inlet channel 9 in the present invention is that there is a certain gap between the semicircular rubber airbag 7 and the gate, and the semicircular rubber airbag 7 seals the gate, so that the gate is in an environment where moisture and dryness alternate, which will accelerate the corrosion damage of the gate. By setting the water inlet channel 9, the water level at the gate is consistent with the water level in the ditch 12, and the gate is always in water, which effectively reduces the corrosion rate of the gate and increases its service life.

[0038] The water inlet channel 9 can be set according to actual conditions. A common retractable hose can be used. A filtering device, generally a filter screen, is set at the mouth of the water inlet channel 9 to effectively prevent large impurities from entering the water inlet channel. The structure adopted by the present invention is as follows: Figure 5 As shown, the water inlet channel 9 includes a venturi-shaped hose 31, and the two ends of the venturi-shaped hose 31 are installed together with the arc-shaped filter cover 30 through a fixing ring 28. The arc-shaped filter cover 30 is provided with a second filter screen 29 inside, and the arc-shaped filter cover 30 is fixed together with the mounting hole provided on the semicircular rubber airbag 7 through an external thread. The double-layer filter cover can effectively filter the sediment and algae in the water to prevent them from entering the gate. At the same time, the use of the venturi-shaped hose 31 can increase the water flow rate, flush the sediment on the filter screen, and play a cleaning role.

[0039] The silt deposited at the gate is separated and deposited on both sides of the gate, which will cause the silt on both sides to be high, which is not conducive to the lifting and lowering of the semicircular rubber airbag 7. The present invention also provides a sand pit 19, which is arranged on both sides of the semicircular rubber airbag 7, and the two sides of the sand retaining plate 11 are located at the center of the sand pit 19. In this way, the separated silt is deposited in the sand pit, which serves the purpose of resource recycling. At the same time, the two sides of the sand retaining plate 11 are located at the center of the sand pit 19. When the gate discharges water, the water flow velocity on both sides of the sand retaining plate 11 is high, which can wash away the silt in the sand pit, playing the role of draining water and clearing sand.

[0040] The solar power supply system 1 is mainly used to supply power to the device of the present invention. It is a conventional device and generally includes a solar cell module, a solar controller, a battery (group) and an inverter, etc., which will not be described in detail.

[0041] The control system includes a control box 2 and a programmable controller arranged in the control box 2, and a PLC controller is generally adopted.

[0042] The air pump 13 and the exhaust valve are connected to the programmable controller respectively.

[0043] The operation process of a water-waste separation device for preventing sediment deposition of the present invention:

[0044] (1) According to the hydrological conditions at the time, the frequency and duration of opening the exhaust valve and the air pump 13 are set. For example, the exhaust valve is opened once every 5 days for 2 minutes. After the exhaust is completed, the air pump 13 is started to inflate the semicircular rubber airbag 7;

[0045] (2) Inflate the semicircular rubber airbag 7, drive the airbag spring 6 to extend, and the semicircular rubber airbag 7 expands to seal the ditch 12 at the edge of the gate frame 3, so that the gate is in a sealed state;

[0046] (3) When the gate is closed: the water flow is in a static state. Under the action of gravity, most of the silt in the water is deposited on both sides of the semi-arc-shaped sand column 10, and a small part is deposited on the semi-circular rubber airbag 7 and the surface of the semi-arc-shaped sand column 10. The control system controls the exhaust valve and the air pump 13 to open. The outlet of the exhaust hose 8 is set at a position lower than the sand retaining plate 11. The exhaust gas flushes the gate, causing the water flow to flow, and then the silt on the surface of the semi-arc-shaped sand column 10 is washed away and flows to the sand accumulation pit 19. At the same time, due to the inflation and deflation process of the semi-circular rubber airbag 7, the semi-circular rubber airbag 7 shrinks and vibrates, driving the silt on the surface to fall off and separate and deposit in the sand accumulation pit 19. The inflation and deflation are very small and will not cause the semi-circular rubber airbag 7 to be retracted under the action of the airbag spring 6, affecting the air tightness;

[0047] (4) When the gate is opened, the semicircular rubber airbag 7 is deflated, and under the action of the airbag spring 6, the semicircular rubber airbag 7 contracts upward. At the same time, as the gate plate moves upward, the first pull rope 4 moves to both sides along the support, opening the gate and performing drainage operation;

[0048] At the same time, under the action of the sand retaining plate 11, the water flow velocity flowing through the sand accumulation pit 19 and the semi-arc sand dividing column 10 area is high, and the sand discharge operation is effectively performed, so that there is almost no sand accumulation in front of the gate when it is closed.

[0049] The above structure can not only effectively solve the problem of silt deposition when the gate is closed, but also promptly flush away the accumulated sand at the gate when the gate is opened, effectively reducing the problem of silt deposition and blockage at the gate and increasing the service life of the gate.

[0050] Example 2

[0051] It is basically the same as Example 1, except that:

[0052] like Figure 4 As shown, a vibration mechanism is provided on the semicircular rubber airbag 7. The vibration mechanism generally adopts an electric vibration rod 23. The provision of the vibration mechanism can further improve the effect of the semicircular rubber airbag 7 in removing sediment by vibration.

[0053] The exhaust hose 8 is connected to the air pump 13 via the three-way valve 22, so that flushing can be performed directly via the air pump 13, thereby improving the flushing effect.

[0054] The sand retaining plate 11 is provided with a trapezoidal hole 18, which is arranged at a distance of 5-10 cm from both sides of the sand retaining plate 11, and the outlet of the trapezoidal hole 18 faces the edge of the semicircular rubber airbag 7. In this way, when draining water, multiple high-flow velocity channels will be formed, and a more efficient flushing operation will be performed in front of the gate.

[0055] The semi-arc sand column 10 in Example 1 is a fixed part, which is arranged at the bottom of the ditch 12 and has a certain influence on the water flow during drainage. Figure 4 As shown, the present invention provides a new semi-arc sand column 10, which is specifically as follows: the semi-arc sand column 10 includes a semi-arc air bag 26 and a counterweight 25 arranged at the bottom of the semi-arc air bag 26, the semi-arc air bag 26 is connected to the air pump 13 or the semi-circular rubber air bag 7 through the air pipe 5, and the present embodiment adopts a structure in which the semi-arc air bag 26 is connected to the semi-circular rubber air bag 7 through the air pipe 5; the sand retaining plate 11 is an arc plate, and the two sides of the sand retaining plate 11 are respectively fixed to the L-shaped connecting rod 24 through a triangular fixing frame 27, and the L-shaped connecting rod 24 is fixed to the gate or the power mechanism, and the semi-arc sand column 10 is fixed to the L-shaped connecting rod 24. In this embodiment, the L-shaped connecting rod 24 is fixed to the motor mechanism, and the power mechanism is an electric hydraulic rod 21.

[0056] By adopting the above structure, the semi-arc-shaped sand column 10 and the sand retaining plate 11 can be raised and lowered according to actual conditions to avoid their influence on the drainage of the gate.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
