Description

Technical Field

[0001] This utility model relates to the field of water intake technology for river channels, and more specifically, to a water intake structure for inland waterways that prevents siltation. Background Technology

[0002] Inland waterway water intake structures come in various forms, commonly including fixed intake heads and movable intake heads. Fixed intake heads are typically installed at specific locations within the inland waterway, introducing river water into subsequent treatment systems via pipelines. Movable intake heads, on the other hand, can be adjusted to some extent according to water level and flow conditions to adapt to different water intake requirements.

[0003] Most of these water intake structures are equipped with water intake filter screens, whose main function is to filter out silt, algae, aquatic plants, and other larger floating debris from the river water, preventing them from entering the water intake pipes and subsequent treatment equipment, and avoiding wear and blockage damage to the equipment. However, existing water intake filter screens have many shortcomings.

[0004] In existing water intake structures, the water intake filter screens are mostly static structures. During long-term water intake, fine impurities such as silt and algae gradually adhere to and accumulate on the filter screen surface. Over time, these impurities accumulate, causing a significant decrease in the filter screen's permeability. When the filter screen's permeability decreases, the water intake flow rate also decreases. To ensure sufficient water intake, it may be necessary to increase the power of the water intake equipment. This not only increases energy consumption but may also place a greater burden on the equipment, shortening its lifespan.

[0005] Moreover, in order to maintain the normal filtration function of the filter screen, the existing water intake structure often requires frequent manual cleaning of the filter screen. Manual cleaning is not only labor-intensive and inefficient, but also requires interrupting water intake operations, which affects the continuity of the entire water intake system, leading to unstable water supply and failing to meet the continuous water demand of industrial production and residential life.

[0006] Existing inland waterway intake structures cannot implement a dynamic dredging method that uses internal cleaning blades within the intake filter screen to automatically rotate and clean the inner wall of the screen using water flow. This dynamic dredging method effectively prevents the accumulation of fine impurities on the filter screen surface, maintains the filter screen's permeability, ensures stable water intake flow, and guarantees water intake efficiency. Furthermore, this method eliminates the need for frequent manual cleaning of the filter screen, improving the automation level and operational continuity of the equipment—a crucial function lacking in existing inland waterway intake structures. Therefore, we propose an anti-clogging inland waterway intake structure. Utility Model Content

[0007] The purpose of this utility model is to address the problems raised in the existing background technology. To achieve the above-mentioned purpose, this utility model provides the following technical solution: a water intake structure for inland waterways that prevents siltation, including a device chassis and support rods set at the four corners of the device chassis. A buffer pad is installed on the bottom of the support rod, and anti-slip texture is engraved on the bottom surface of the buffer pad. A water intake pump is installed sequentially on the top center section of the device chassis. A flow pipe is embedded in the right-side pipe opening of the water intake pump, and the other end of the flow pipe is connected to a diversion pipe.

[0008] As a preferred technical solution of this utility model, the water intake pump, the flow pipe, and the redirection pipe are all provided in threes, arranged in a linear array.

[0009] As a preferred technical solution of this utility model, an M-shaped diversion pipe is connected inside the upper opening of the redirecting pipe, and a diversion pipe connecting flange is nested below the M-shaped diversion pipe, and the diversion pipe connecting flange is connected to the redirecting pipe.

[0010] As a preferred technical solution of this utility model, a water supply pipe is embedded in the port of the M-shaped diversion pipe, and a pipe pressure gauge is connected above the water supply pipe.

[0011] As a preferred technical solution of this utility model, the other end of the water supply pipe is connected to the water intake pipe, and the connection end between the two is nested with a water intake pipe connection flange, wherein a filter screen mounting base is fixed at the front end of the water intake pipe.

[0012] As a preferred technical solution of this utility model, a water intake filter screen is installed on the filter screen mounting base, and the inside of the water intake filter screen is provided with a filter screen inner wall cleaning fan blade.

[0013] As a preferred technical solution of this utility model, a water intake and outflow pipe is embedded in the left side of the water intake pump, and a water outlet pipe connecting flange is provided on the water intake and outflow pipe, and a flow rate regulating valve is installed on the outside of the water outlet pipe connecting flange.

[0014] As a preferred technical solution of this utility model, the water intake and outlet pipe, the connecting flange of the outlet pipe, and the flow rate regulating valve are also provided with three linear ones.

[0015] Compared with existing technologies, the internal cleaning fan blades of this utility model, installed inside the water intake filter screen, automatically rotate under the action of water flow to clean the mud, algae, and other fine impurities adhering to the inner wall of the filter screen. This dynamic cleaning method prevents the accumulation of fine impurities on the filter screen surface, maintains the permeability of the filter screen, ensures a stable water intake flow, guarantees water intake efficiency, eliminates the need for frequent manual cleaning of the filter screen, and improves the automation level and operational continuity of the equipment.

[0016] The M-shaped diversion pipe design can rationally distribute water flow from multiple diversion pipes, ensuring uniform water flow throughout the pipeline system and preventing excessively large or small local flows, thereby improving the overall water delivery efficiency of the water intake system. The flow rate regulating valve installed at the outlet of the water intake diversion pipe can flexibly adjust the water flow rate according to actual water demand or the flow requirements of subsequent water-using equipment.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1: A water intake structure for preventing siltation in inland waterways includes a device chassis 1 and support rods 2 set at the four corners of the device chassis 1. A buffer pad 3 is installed on the bottom of the support rod 2, and anti-slip texture is engraved on the bottom surface of the buffer pad 3. A water intake pump 4 is installed sequentially on the top center section of the device chassis 1. A flow pipe 5 is embedded in the right pipe opening of the water intake pump 4, and the other end of the flow pipe 5 is connected to a diversion pipe 6.

[0030] The water intake pump 4, the flow pipe 5, and the diversion pipe 6 are each provided in threes, arranged in a linear array. An M-shaped diversion pipe 7 is connected to the upper opening of the diversion pipe 6, and a diversion pipe connecting flange 8 is nested below the M-shaped diversion pipe 7. The diversion pipe connecting flange 8 and the diversion pipe 6 are connected.

[0031] A water supply pipe 10 is embedded in the port of the M-shaped diversion pipe 7, and a pipe pressure gauge 9 is connected above the water supply pipe 10. The other end of the water supply pipe 10 is connected to a water intake pipe 11, and a water intake pipe connecting flange 12 is nested at the connection end between the two. A filter screen mounting base 13 is fixed at the front end of the water intake pipe 11.

[0032] A water intake filter screen 14 is installed on the filter screen mounting base 13, and the inside of the water intake filter screen 14 is equipped with a filter screen inner wall cleaning fan blade 15. A water intake diversion outlet pipe 16 is embedded in the left pipe opening of the water intake pump 4. A water outlet pipe connecting flange 17 is provided on the outlet pipe opening of the water intake diversion outlet pipe 16, and a flow rate regulating valve 18 is installed on the outside of the water outlet pipe connecting flange 17. There are three water intake diversion outlet pipes 16, water outlet pipe connecting flanges 17, and flow rate regulating valves 18, arranged in a linear pattern.

[0033] Working principle of the anti-siltation inland waterway water intake structure: The main function of this water intake structure is to draw water from inland waterways and prevent siltation during the water intake process. Its operation involves using a water intake pump to draw river water into the intake pipe, which then transports and diverts the water through a series of pipelines before finally discharging it from the intake outlet pipe. Simultaneously, a water intake filter screen and silt-removing fan blades are used to prevent siltation.

[0034] The base 1 serves as the foundation of the entire water intake structure, providing installation support for other components. The support rods 2 at the four corners further enhance the stability of the device. The buffer pads 3 installed on the base rods reduce the impact force between the device and the ground or riverbed. At the same time, the anti-slip texture engraved on the bottom surface of the buffer pads 3 increases friction, preventing the device from sliding or displacing under the impact of water flow or other external forces, ensuring that the entire water intake structure remains stable during operation.

[0035] The water intake pump 4 is the power source for the entire water intake system. When the water intake pump 4 is started, it creates a negative pressure inside, thereby generating suction and causing water in the inland waterway to enter the water intake system.

[0036] Water drawn in by the right-side inlet of the water intake pump 4 enters the flow pipe 5. The flow pipe 5 delivers the water to the redirecting pipe 6, which changes the direction of the water flow, directing it towards the M-shaped diversion pipe 7. Here, three water intake pumps 4, flow pipes 5, and redirecting pipes 6 are arranged in a linear array, which increases the water intake flow rate and improves water intake efficiency.

[0037] An M-shaped diversion pipe 7 is connected to the upper opening of the diversion pipe 6. The M-shaped diversion pipe 7 serves to divert water flow, rationally distributing the water flow from multiple diversion pipes 6. The diversion pipe connecting flange 8 nested below the M-shaped diversion pipe 7 is used to connect the diversion pipe 6 and the M-shaped diversion pipe 7, ensuring the connection is airtight and preventing water leakage.

[0038] The water supply pipe 10 embedded in the inlet of the M-shaped diversion pipe 7 continues to transport the diverted water. The pipe pressure gauge 9 connected above the water supply pipe 10 can monitor the water pressure in the pipe in real time. By monitoring the water pressure, the working status of the water intake system can be understood in a timely manner, and it can be determined whether there are any abnormalities such as blockages or leaks, so that corresponding measures can be taken in a timely manner.

[0039] The other end of the water supply pipe 10 is connected to the water intake pipe 11, and the two are connected by a water intake pipe connecting flange 12 to ensure a firm and sealed connection. A filter screen mounting base 13 is fixed to the front end of the water intake pipe 11, on which a water intake filter screen 14 is installed. When river water enters from the water intake pipe 11, the water intake filter screen 14 can filter out larger impurities in the water, such as branches, weeds, and stones, preventing these impurities from entering the water intake system and causing pipe blockage or equipment damage.

[0040] The cleaning fan 15 inside the water intake filter screen 14 rotates with the water flow. The rotation of the cleaning fan 15 can clean the mud, sand, algae and other fine impurities attached to the inner wall of the water intake filter screen 14, preventing these impurities from accumulating on the inner wall of the filter screen, thus ensuring the filtration effect of the water intake filter screen 14 and avoiding the impact on water intake efficiency due to clogging.

[0041] A water intake and discharge pipe 16 is embedded in the left side opening of the water intake pump 4. Water treated by the water intake system is discharged through the water intake and discharge pipe 16. The water intake and discharge pipe 16 is equipped with a discharge pipe connection flange 17 for connecting other equipment or pipes.

[0042] The flow rate regulating valve 18 installed on the outside of the outlet pipe connecting flange 17 can regulate the water flow rate. Based on actual needs, such as the flow rate requirements of subsequent water-using equipment and the operating status of the water intake system, the flow rate in the water intake branch outlet pipe 16 can be controlled by adjusting the flow rate regulating valve 18, ensuring the stable and efficient operation of the entire water intake system. Similarly, three water intake branch outlet pipes 16, outlet pipe connecting flanges 17, and flow rate regulating valves 18 are arranged in a linear array to match the preceding water intake components, achieving high efficiency and stability throughout the entire water intake process.

[0043] The working process of the anti-siltation inland waterway water intake structure: Preparation stage: Installation and commissioning of the device. Place the device chassis 1 stably in a suitable position in the inland waterway, ensuring that the support rods 2 at the four corners are in full contact with the ground or riverbed. Check whether the buffer pad 3 is firmly installed and whether the anti-slip texture can effectively prevent slippage, ensuring the stability of the entire device and preventing it from shaking or shifting due to water flow impact.

[0044] Connect the water intake pump 4, flow pipe 5, diversion pipe 6, M-shaped branch pipe 7, water supply pipe 10, and water intake pipe 11 in sequence. Use the branch pipe connecting flange 8 and the water intake pipe connecting flange 12 to ensure that all pipes are tightly connected and leak-free.

[0045] Check the connection status of the water intake and outlet pipe 16, the outlet pipe connecting flange 17, and the flow rate regulating valve 18, and adjust the flow rate regulating valve 18 to a suitable initial opening.

[0046] Check if the pipeline pressure gauge 9 can display the pressure normally, ensuring its accuracy and reliability. At the same time, check if the water intake filter screen 14 is installed on the filter screen mounting base 13 and is securely installed.

[0047] Equipment inspection and start-up preparation: Conduct a comprehensive inspection of the water intake pump 4, including the integrity of the motor and pump body components, to ensure that it is in normal working condition.

[0048] Connect the power supply and conduct a no-load test run of the equipment. Observe the operation of each component, such as whether the motor is running normally and whether there is abnormal vibration in the pipeline. If any problems are found, stop the machine immediately to troubleshoot and resolve them.

[0049] Water intake phase: Start the water intake pump 4. The motor drives the pump body to operate, creating a negative pressure inside the pump body. The suction force generated by this negative pressure causes water in the inland waterway to enter the water intake system through the water intake pipe 11.

[0050] The river water first passes through the water intake filter screen 14 at the front end of the water intake pipe 11. The water intake filter screen 14 intercepts larger impurities in the water, such as branches, aquatic plants, and stones, preventing these impurities from entering subsequent pipes and equipment and avoiding blockages or damage.

[0051] Meanwhile, the cleaning fan blades 15 inside the water intake filter screen 14 rotate with the water flow. The rotation of the cleaning fan blades 15 can continuously clean the mud, sand, algae and other fine impurities attached to the inner wall of the water intake filter screen 14, preventing these impurities from accumulating on the inner wall of the filter screen and ensuring the filtration effect of the water intake filter screen 14 and the smooth passage of water.

[0052] Water flow delivery and diversion: Filtered water enters the water intake pump 4, and under the action of the pump, the water flows into the flow pipe 5 through the right-side pipe opening.

[0053] The flow pipe 5 delivers water to the redirecting pipe 6, which changes the direction of the water flow, directing it towards the M-shaped diversion pipe 7. Because three water intake pumps 4, the flow pipe 5, and the redirecting pipe 6 are arranged in a linear array, the simultaneous operation of multiple pumps increases the water intake flow rate and improves water intake efficiency.

[0054] Water flow diversion and pressure monitoring: Water in the diversion pipe 6 flows into the M-shaped diversion pipe 7, which diverts the water flow and distributes it reasonably to each water supply pipe 10.

[0055] The pressure gauge 9 above the water supply pipeline 10 monitors the water pressure in the pipeline in real time. Operators can judge the working status of the water intake system based on the pressure display. For example, an abnormally high pressure may indicate a blockage in the pipeline, and an abnormally low pressure may indicate a leak, so that appropriate measures can be taken in a timely manner.

[0056] After a series of transport and diversion processes, water enters the intake water diversion outlet pipe 16 through the left port of the intake pump 4. Operators can control the water flow rate in the intake water diversion outlet pipe 16 by adjusting the flow rate regulating valve 18 according to actual needs, such as the flow rate requirements of subsequent water-using equipment and the working status of the water intake system, to ensure that the entire water intake system can operate stably and efficiently.

[0057] Shutdown and Maintenance Phase: When the water intake task is completed or the water intake operation needs to be stopped, first turn off the power to the water intake pump 4 to stop the pump's operation. At this time, the water flow stops, and the water intake process ends. Check the impurities trapped on the water intake filter screen 14, and clean the debris from the filter screen in a timely manner to ensure good filtration effect for the next use. Check all pipe connections for leaks, and replace or tighten the seals if necessary.

[0058] Calibrate and inspect the pipeline pressure gauge 9 to ensure its accuracy. Maintain the flow rate regulating valve 18 by applying lubricant to ensure its smooth adjustment. Regularly maintain the water intake pump 4, such as checking the motor insulation performance and adding lubricating oil, to extend the service life of the equipment.
