Description

Technical Field

[0001] The utility model relates to the technical field of river water intake, in particular to an extraction type river water intake device. Background Art

[0002] Rivers are the conventional water sources for people's domestic water and irrigation water. Since rivers are usually at a lower level, water pumps are generally used to pump water to higher levels when taking water from rivers. This not only causes energy loss, but is also subject to power restrictions. In addition, in traditional agriculture, there is also a method of using a water wheel to take water from a low place to a high place, but this method of taking water from a high place is limited by the height of the water wheel. If you want to take water to a higher place, you need to use a water wheel with a large diameter, which makes the operating structure of this method huge, expensive and inconvenient to maintain.

[0003] Therefore, how to design a river water intake device that does not require additional electrical energy and has a controllable and adjustable water intake height has become a problem that technical personnel in this field need to consider. Utility Model Content

[0004] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the utility model is: how to provide a pumping river water intake device which does not consume additional electricity, can directly utilize river water sources and hydraulic power to intake water, is energy-saving and environmentally friendly, and has adjustable water intake height.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A pumping river water intake device includes an impeller and a piston device. The impeller is arranged in the direction of the river water flow and the lower part is immersed under the water surface of the river. The impeller and the piston device are connected by a piston transmission and drive them to reciprocate. The water inlet end of the piston device is connected to the bottom of the river water surface through an inlet pipe, and the water outlet end of the piston device is connected to a sedimentation tank located above through an outlet pipe. An overflow outlet is provided on one side of the sedimentation tank.

[0007] In this way, the river water impacts the impeller to rotate, and then drives the piston to reciprocate to pump water, and the river water can be pumped upward to the sedimentation tank for sedimentation, and then overflow and flow out. Therefore, there is no need to consume extra electricity to pump water to a higher place, and by applying pressure from the piston to pump water to a higher place, the water pressure can be increased by reducing the outlet pipe, so as to adjust the pumping height.

[0008] Furthermore, the bottom of the sedimentation tank is inclined downwardly on one side close to the river channel, and a sand discharge gate valve is provided at the bottom of the side wall of the sedimentation tank on this side.

[0009] In this way, the sediment settled in the sedimentation tank can be easily moved to the side of the sand discharge valve, and when the sand needs to be discharged, the sand discharge valve can be opened to discharge the sand, thereby completing the sand cleaning, and the discharged sand flows back into the river channel along the water flow.

[0010] Furthermore, a water storage and sand flushing pool is provided at a high position above the sedimentation pool, a water outlet control valve is provided at the outlet of the water outlet pipe, a water distribution pipe is provided on the water outlet pipe for upward communication, the upper end of the water distribution pipe is connected to the mouth of the water storage and sand flushing pool, a water distribution control valve is provided on the water distribution pipe, a sand flushing pipe is provided at the bottom of the water storage and sand flushing pool for downward communication, the lower end of the sand flushing pipe is provided opposite to the higher end of the bottom of the sedimentation pool, and a sand flushing control valve is installed on the sand flushing pipe.

[0011] In this way, when the sedimentation tank needs to be cleared of sand, the water outlet control valve can be closed, the water diversion control valve can be opened, the river water can be pumped to the water storage and sand flushing tank to store water, and then the sand flushing control valve can be opened to release water for flushing, so that sand can be better discharged by flushing with water flow.

[0012] Furthermore, the piston device includes a horizontally arranged water-drawing box, in which a piston is arranged along the width direction of the water-drawing box and can slide along the length direction of the water-drawing box, a pull rod extending out of the water-drawing box is vertically arranged at one end of the piston, and the outer end of the pull rod is connected to the rotating shaft of the impeller through a reciprocating transmission mechanism. A water inlet and a water outlet are provided at the inner end of the water-drawing box away from the piston, a water inlet check valve is provided at the water inlet and is connected to the water inlet pipe, and a water outlet check valve is provided at the water outlet and is connected to the water outlet pipe.

[0013] In this way, the river water flow impels the impeller to rotate, and drives the piston to reciprocate through the reciprocating transmission mechanism. When the piston moves outward, the water inlet check valve opens and the water outlet check valve closes, so that the river water is drawn from the water inlet pipe into the water pumping tank; when the piston moves inward, the water inlet check valve closes and the water outlet check valve opens, so that the river water is pressed out of the water pumping tank into the water outlet pipe to achieve water pumping. In this way, the water flow is used to directly drive the impeller to rotate to generate power to pump water, which is more energy-saving and environmentally friendly, and is reliable, stable, and more practical.

[0014] Furthermore, the reciprocating transmission mechanism includes a sliding sleeve fixed vertically to the outer end of the pull rod, and also includes a slider that can be slid up and down in the sliding sleeve. The slider is installed and fixed at an external position on the side of a turntable. The turntable is relatively installed above the impeller and the turntable shaft is connected to the impeller's rotating shaft through a transmission belt.

[0015] In this way, the impeller is driven by the water flow to rotate, driving the turntable to rotate, and then driving the piston to reciprocate through the cooperation of the slider and the sleeve. The structure is simple and the transmission is reliable and stable.

[0016] Furthermore, the piston device is installed above the water surface of the river channel through a mounting frame fixed in the air on the river bank, so that the lower end of the impeller is conveniently immersed under the water surface.

[0017] Furthermore, the rotating shaft of the impeller is rotatably mounted in a bearing, one end of the bearing is slidably mounted in a vertical slide groove on the mounting frame, and the other end of the bearing is fixed to a float through a horizontally arranged bearing frame, and the float floats in the river.

[0018] In this way, the float can rise and fall with the rise and fall of the water level in the river, thereby ensuring that the lower end of the impeller is always at a fixed deep position below the water surface, so that the operation of the device will not be affected by the water level.

[0019] Furthermore, a float limiting structure is provided, which includes a foundation pile vertically installed in the river channel, the foundation pile has a rectangular cross-section, and the float is provided with a matching vertical sliding hole corresponding to the foundation pile and can be slidably installed on the foundation pile up and down.

[0020] In this way, the horizontal position limitation of the float can be well achieved, and the working stability of the device can be ensured.

[0021] Furthermore, a roller is arranged on the inner surface of the vertical sliding hole of the float.

[0022] In this way, the rolling friction between the roller and the pile makes it easier for the float to slide up and down.

[0023] Furthermore, an adjusting tank is provided on the float, in which an adjusting water pipe is provided, one end of the adjusting water pipe is located at the bottom of the adjusting tank, and the other end is located below the water surface of the river channel, and a forward and reverse control pump is installed on the adjusting water pipe.

[0024] In this way, the amount of water stored in the regulating tank can be controlled by controlling the pump in forward and reverse rotation, thereby adjusting the draft of the float and the impeller, thereby achieving the adjustment of the pumping head height of the piston device, and achieving the adjustment of the water discharge rate under a fixed pumping height.

[0025] Furthermore, a float lifting control device is provided, which includes a control motor with forward and reverse output functions. The output shaft of the control motor is meshed with a nut with teeth on the outer circumference through a gear. The nut is rotatably mounted on a positioning pile. A control screw is screwed in the nut. The control screw has a light rod section with a rectangular cross-section. The light rod section is fitted in a matching anti-rotation sleeve. The anti-rotation sleeve is fixed relative to the river bank. A lifting rope is connected to the front end of the control screw. The lifting rope is fixedly connected to the float from top to bottom after being turned by the steering wheel.

[0026] In this way, when water is not needed, the control screw can be driven to move horizontally by controlling the motor output, thereby pulling the float and the impeller upward as a whole, so that the impeller is out of the water surface, avoiding the impeller and the one-way valve from being ineffective for a long time and being quickly worn out. The device controls the lifting rope through the structure of the lead screw nut, and the self-locking effect of the nut can be used to ensure that the gravity after the impeller is lifted will not act on the motor, thereby extending the service life of the motor.

[0027] Furthermore, an intermediate wheel is provided obliquely above the impeller shaft, the intermediate wheel is mounted on one end of a lever arm, the other end of the lever arm is mounted on the impeller shaft, a slide groove is provided in the middle of the lever arm and is mounted on a fulcrum shaft fixed on the mounting frame, and the transmission belt is sleeved between the intermediate wheel, the turntable shaft and the impeller shaft.

[0028] In this way, during the adjustment process, when the impeller moves upward along the vertical slide groove, the intermediate wheel will be driven to move synchronously to the far end through the action of the lever arm, ensuring that the triangular transmission belt is always in a tensioned state, thereby better realizing the stable adjustment of the impeller up and down.

[0029] To sum up, the utility model can directly utilize river water sources and hydraulic power to draw water without consuming additional electricity, is more energy-saving and environmentally friendly, and has the advantages of good stability and flexible and adjustable water intake height.

An overflow outlet 6 is provided on one side of the sedimentation tank 5.

[0034] In this way, the river water impacts the impeller to rotate, and then drives the piston to reciprocate to pump water, and the river water can be pumped upward to the sedimentation tank for sedimentation, and then overflow and flow out. Therefore, there is no need to consume extra electricity to pump water to a higher place, and by applying pressure from the piston to pump water to a higher place, the water pressure can be increased by reducing the outlet pipe, so as to adjust the pumping height.

[0035] The bottom of the sedimentation tank 5 is inclined downward near the river channel, and a sand discharge gate valve 7 is provided at the bottom of the side wall of the sedimentation tank.

A pull rod 12 extending out of the water drawing box 11 is vertically arranged at one end of the piston 2. The outer end of the pull rod 12 is connected to the rotating shaft of the impeller 1 through a reciprocating transmission mechanism. A water inlet and a water outlet are opened at the inner end of the water drawing box 11 away from the piston direction. A water inlet check valve is arranged at the water inlet and is connected to the water inlet pipe 3. A water outlet check valve is arranged at the water outlet and is connected to the water outlet pipe 4.

[0040] In this way, the river water flow impels the impeller to rotate, and drives the piston to reciprocate through the reciprocating transmission mechanism. When the piston moves outward, the water inlet check valve opens and the water outlet check valve closes, so that the river water is drawn from the water inlet pipe into the water pumping tank; when the piston moves inward, the water inlet check valve closes and the water outlet check valve opens, so that the river water is pressed out of the water pumping tank into the water outlet pipe to achieve water pumping. In this way, the water flow is used to directly drive the impeller to rotate to generate power to pump water, which is more energy-saving and environmentally friendly, and is reliable, stable, and more practical.

[0042] In this way, the impeller is driven by the water flow to rotate, driving the turntable to rotate, and then driving the piston to reciprocate through the cooperation of the slider and the sleeve. The structure is simple and the transmission is reliable and stable.

[0043] The piston device is installed above the water surface of the river channel by means of a mounting frame 16 suspended and fixed on the river bank, so that the lower end of the impeller can be immersed under the water surface.

[0044] The rotating shaft of the impeller 1 is rotatably mounted in a bearing, one end of the bearing is slidably mounted in a vertical slide groove 17 on a mounting frame 16, and the other end of the bearing is fixed to a float 19 through a horizontally arranged bearing frame 18, and the float 19 floats in the river.

[0045] In this way, the float can rise and fall with the rise and fall of the water level in the river, thereby ensuring that the lower end of the impeller is always at a fixed deep position below the water surface, so that the operation of the device will not be affected by the water level.

One end of the regulating water pipe 22 is located at the bottom of the adjusting groove 21, and the other end is located below the water surface of the river.

The lifting rope 29 is fixedly connected to the float 19 from top to bottom after being turned by the steering wheel 30.

[0053] In this way, when water is not needed, the control screw can be driven to move horizontally by controlling the motor output, thereby pulling the float and the impeller upward as a whole, so that the impeller is out of the water surface, avoiding the impeller and the one-way valve from being ineffective for a long time and being quickly worn out. The device controls the lifting rope through the structure of the lead screw nut, and the self-locking effect of the nut can be used to ensure that the gravity after the impeller is lifted will not act on the motor, thereby extending the service life of the motor.
