Description

Technical Field

[0001] This invention relates to a multifunctional adjustable eddy current elimination and impurity removal device, belonging to the technical field of water conservancy facilities. Background Technology

[0002] Vortex formation within the intake structure of pumping stations has always been a challenging engineering problem, with surface vortices in the intake pool being a significant and unavoidable phenomenon. These surface vortices typically exist before the pump inlet in the intake pool, and their presence often leads to the accumulation of floating debris. These vortices and floating debris not only affect the stability of the water flow but can also seriously jeopardize the safety and efficiency of the pumping station. Firstly, they cause uneven water flow distribution, increasing the velocity differences within the intake pool, which increases the pump's workload and reduces its efficiency. Secondly, vortex areas can trigger cavitation, damaging the pump body and other equipment, and shortening their lifespan. More importantly, the formation of vortices can also lead to the concentration and deposition of impurities in the intake pool, affecting water quality and consequently impacting downstream water treatment systems. Therefore, implementing effective prevention and control measures is crucial for ensuring the safe operation of pumping stations and the efficient utilization of water resources. Currently, fixed vortex-eliminating grids are commonly used to eliminate surface vortices in the intake pool. However, in actual engineering operations, surface vortices typically exhibit unstable movement, their positions constantly changing, and their frequency of occurrence is not fixed. Therefore, the effectiveness of these vortex-eliminating measures is limited. In the absence of vortices, existing vortex-eliminating grids can have the opposite effect, leading to the accumulation of floating debris near the vortex-eliminating device.

Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multifunctional adjustable vortex elimination and impurity removal device that can adjust the vortex elimination ring to rotate and eliminate vortices according to the actual vortex formation situation, thereby improving the vortex elimination effect and reducing the wear and tear of the water pump components.

[0005] To achieve the above objectives, the present invention is implemented using the following technical solution:

[0006] In a first aspect, this application provides a multifunctional adjustable vortex elimination and impurity removal device, including an inlet pool, a water pump assembly, a vortex elimination assembly, and a controller; the water pump assembly is disposed in the inlet pool.

[0007] The vortex-eliminating assembly includes a linear slide rail, a vortex-eliminating ring, a first telescopic mechanism, and a second telescopic mechanism. The linear slide rail is mounted on the water inlet pool and is close to the water pump assembly. The fixed end of the first telescopic mechanism is located above the linear slide rail, and the movable end extends towards the water inlet pool. The fixed end of the second telescopic mechanism is perpendicularly connected to the movable end of the first telescopic mechanism, and the movable end is equipped with a power motor. The vortex-eliminating ring is fixedly connected to the shaft of the power motor. The bottom of the vortex-eliminating ring is equipped with a hook.

[0008] The controller is connected to the linear slide rail, the first telescopic mechanism, the second telescopic mechanism, and the power motor, respectively.

[0009] Furthermore, the anti-vortex ring includes a third telescopic mechanism, a fourth telescopic mechanism, a coupling disc, a fixed base, and an annular elastic ring; multiple third telescopic mechanisms are respectively disposed on the outer periphery of the fixed base; the annular elastic ring is disposed on the outer periphery of the fixed base and is fixedly connected to the telescopic ends of multiple third telescopic mechanisms; the hook is disposed on the third telescopic mechanism;

[0010] The fixed base is fixedly connected to the coupling plate via a connecting shaft; multiple fourth telescopic mechanisms are hinged to the coupling plate; the telescopic ends of the fourth telescopic mechanisms are respectively fixedly connected to the annular elastic ring; the controller is electrically connected to the third telescopic mechanism and the fourth telescopic mechanism respectively.

[0011] Furthermore, the third and fourth telescopic mechanisms are hydraulic thrust telescopic rods, respectively.

[0012] Furthermore, the water pump assembly includes an outlet pipe and a water pump; the water pump is located inside the inlet pool; one end of the outlet pipe is connected to the water pump, and the other end extends out of the inlet pool and is connected to external equipment.

[0013] Furthermore, the linear slide rail includes a slide track and a slide groove; the two slide tracks are respectively located on the inner and outer sides of the pool wall of the water inlet pool; the slide track is provided with a gear that meshes with the comb teeth provided on the slide groove; the matching slide groove is provided with comb teeth; the shaft of the drive motor provided on the slide track is fixedly connected to the gear; the controller is connected to the drive motor.

[0014] Furthermore, the first telescopic mechanism includes a hydraulic cylinder; the hydraulic cylinder is fixed on the linear slide rail; the piston rod of the hydraulic cylinder extends toward the water inlet pool; and the controller is electrically connected to the hydraulic cylinder.

[0015] Furthermore, a rotating power disk is provided on the linear slide rail; the first telescopic mechanism is fixed to the rotating power disk; the controller is electrically connected to the rotating power disk and drives the rotating power disk to drive the first telescopic mechanism to rotate within a preset range.

[0016] Furthermore, the second telescopic mechanism includes an electrically operated telescopic rod; the controller is electrically connected to the electrically operated telescopic rod.

[0017] Furthermore, an intelligent monitor is installed on the water inlet pool; the intelligent monitor is electrically connected to the controller.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0019] This invention provides a multifunctional adjustable vortex elimination and debris removal device. A linear slide rail drives a first telescopic mechanism and a second telescopic mechanism to move laterally left and right, allowing the vortex-eliminating ring to move flexibly left and right relative to the water pump assembly, eliminating vortices generated by the water pump assembly in the left and right positions. Similarly, the first telescopic mechanism extends and retracts relative to the water pump assembly, allowing the vortex-eliminating ring to move flexibly back and forth relative to the water pump assembly, eliminating vortices generated by the water pump assembly in the front and back positions. The second telescopic mechanism drives the vortex-eliminating ring to move up and down. The purpose of this design is to adjust the depth of the vortex-eliminating ring entering the water surface, so as to quickly eliminate vortices of different sizes and improve the service life of the water pump assembly. In addition, various floating debris may exist at the vortex location. The hook set below the vortex-eliminating ring can suspend the debris during the vortex elimination process. After the vortex is eliminated, the controller controls each telescopic mechanism to collect the debris, which is convenient for processing and avoids the impact of floating debris on this device and other cooperating equipment.

[0020] The anti-vortex ring provided in this application can expand the anti-vortex area itself. The extension of the third telescopic mechanism increases the diameter of the annular elastic ring and expands the anti-vortex area. In order to improve the strength of the anti-vortex ring, a fourth telescopic mechanism is used to assist the third telescopic mechanism in supporting the elastic anti-vortex ring.

[0021] This application has a rotating power disk installed on a linear device. The controller controls the rotation of the rotating power disk, which drives the first telescopic mechanism to rotate, so that the anti-vortex ring can eliminate vortices within an arc range of different radii.

[0028] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention. Example

[0029] Combination Figures 1 to 5 This embodiment provides a multifunctional adjustable vortex suppression and impurity removal device, including an inlet tank 1, a water pump assembly, a vortex suppression assembly, and a controller. The water pump assembly is installed inside the inlet tank 1 and includes an outlet pipe 3 and a water pump 2. The water pump 2 is installed inside the inlet tank 1, with one end of the outlet pipe 3 connected to the water pump 2 and the other end extending out of the inlet tank 1 to communicate with external equipment. The vortex suppression assembly includes a linear slide rail 7, a vortex suppression ring 4, a first telescopic mechanism 5, and a second telescopic mechanism 6. The linear slide rail 7 is installed on the inlet tank 1 and positioned close to the water pump assembly. The controller can be installed on the inlet tank 1 or separately, depending on actual needs. The controller is electrically connected to the linear slide rail 7 and drives the linear slide rail 7 to move left and right relative to the water pump assembly.

[0030] The fixed end of the first telescopic mechanism 5 is mounted on the linear slide rail 7, such as Figure 2 The first telescopic mechanism 5 is driven to move left and right by the linear guide rail 7. The movable end of the first telescopic mechanism 5 extends towards the inlet pool 1. The controller is electrically connected to the first telescopic mechanism 5 and controls the first telescopic mechanism 5 to move back and forth relative to the water pump assembly. The fixed end of the second telescopic mechanism 6 is installed on the movable end of the first telescopic mechanism 5 and is perpendicularly connected to the movable end of the first telescopic mechanism 5. The controller is electrically connected to the second telescopic mechanism 6 and controls the second telescopic mechanism 6 to move up and down. A power motor 10 is installed on the movable end of the second telescopic mechanism 6, and the shaft of the power motor 10 is fixedly connected to the anti-vortex ring 4. The controller is electrically connected to the power motor 10 and controls the anti-vortex ring 4 to rotate to eliminate vortices. The bottom of the anti-vortex ring 4 is provided with 14. During the vortex elimination process, it will attract surrounding floating garbage. While rotating to eliminate vortices, the anti-vortex ring 4 can catch the floating garbage, reduce the impact of floating garbage on this device and other cooperating equipment, and improve the working efficiency of the pump station.

[0031] During vortex elimination, the controller controls the linear slide rail 7 to drive the first telescopic mechanism 5 and the vortex elimination ring 4 to move left and right relative to the water pump assembly, and at the same time, according to the actual vortex position; further, the controller controls the first telescopic mechanism 5 to drive the vortex elimination ring 4 to move back and forth relative to the water pump assembly to eliminate vortices; based on the observed size and rotation speed of the vortex, the controller controls the second telescopic mechanism 6 to make the vortex elimination ring 4 move up and down, adjusting the depth of the vortex elimination ring 4 inserted into the water inlet pool 1 to quickly eliminate vortices, so as to reduce the wear and tear on the water pump assembly.

[0032] In some embodiments, such as Figure 5 The vortex-suppressing ring specifically includes a third telescopic mechanism 12, a fourth telescopic mechanism 13, a coupling disc 15, a fixed base 24, and an annular elastic ring 19. Multiple third telescopic mechanisms 12 are fixed at equal intervals to the outer periphery of the fixed base 24. The annular elastic ring 19 is disposed on the outer periphery of the fixed base 24, with the telescopic end of each third telescopic mechanism 12 fixedly connected to the annular elastic ring 19. This configuration uses the third telescopic mechanism 12 as a variable-length vortex-suppressing plate. Under the action of the third telescopic mechanism 12, the annular elastic ring 19 expands outward, increasing the vortex-suppressing area to better handle vortices of various sizes. A 14 is installed at the bottom of the third telescopic mechanism 12.

[0033] like Figure 5 A coupling disc 15 is fixed above the fixed base 24 via a connecting shaft. This coupling disc 15 is fixedly connected to the shaft of the power motor 10 via connecting bolts 18. Multiple fourth telescopic mechanisms 13 are hinged to the outer periphery of the coupling disc 15, and the telescopic end of each fourth telescopic mechanism 13 is fixedly connected to an annular elastic ring 19. When the third telescopic mechanism 12 extends, causing the annular elastic ring 19 to expand and jointly eliminate vortices, the force of the vortices can damage the third telescopic mechanism 12 and other structures. The fourth telescopic mechanism 13 simultaneously expands and contracts in coordination with the third telescopic mechanism 12, improving the overall strength of the device and extending its service life. The controller is electrically connected to both the third telescopic mechanism 12 and the fourth telescopic mechanism 11, controlling their telescopic movements.

[0034] Specifically, in this embodiment, both the third telescopic mechanism 12 and the fourth telescopic mechanism 13 can be hydraulic thrust telescopic rods. 14 is installed on the outermost telescopic rod of the first hydraulic telescopic rod 20 of the third telescopic mechanism 12. The first hydraulic oil tank 21 of the third telescopic mechanism 12 replaces the fixed seat 24 in the above embodiment. The first hydraulic telescopic rod 20 is controlled to extend and retract by the first hydraulic oil tank 21 on the fixed seat 24.

[0035] In some embodiments, such as Figure 5The document describes the hinge connection between the coupling disc 15 and the fourth telescopic mechanism 13: Multiple pulleys 16 are arranged on the outer periphery of the coupling disc 15, each pulley 16 being rotatably connected to the coupling disc 15 via a bracket 16. The second hydraulic oil tank 23 in the fourth telescopic mechanism 13 is fixed to the pulleys 16, the fixed end of the second hydraulic telescopic rod 22 is fixed to the second hydraulic oil tank 23, and the telescopic end is fixedly connected to the annular elastic ring 18.

[0036] In some embodiments, such as Figures 1 to 3 A smart monitor 9 is installed on the inlet pool 1, and the smart monitor 9 is electrically connected to the controller. The smart monitor 9 detects the position and size of the vortex and transmits this information to the controller for calculation and judgment, thereby controlling the position and depth of the vortex-suppressing ring 4 to accurately suppress the vortex. The information transmission and judgment between the smart monitor 9 and the controller are existing technologies, and the settings are determined by relevant personnel based on the actual application environment.

[0037] In some embodiments, the linear guide rail 7 includes a slide rail and a chute. Two slide rails are respectively installed on the inner and outer sides of the pool wall of the water inlet pool 1. A fixed drive motor is mounted on the slide rail. The shaft of the drive motor is fixedly connected to a gear, driving the gear to rotate. The chute is fitted above the slide rail, and the comb teeth on the chute mesh with the gear. A controller is connected to the drive motor, controlling the drive motor to rotate, thereby driving the gear to rotate, causing the meshing chute to move left and right relative to the slide rail. The linear guide rail 7 provided in this application is an existing product, and detailed structural connection methods are not provided here.

[0038] In some embodiments, the first telescopic mechanism 5 includes a hydraulic cylinder. The hydraulic cylinder is fixedly mounted on the linear slide rail 7. The piston rod of the hydraulic cylinder extends towards the water inlet pool 1. Controlling the extension and retraction of the piston rod of the hydraulic cylinder, as electrically connected to the control mechanism, enables the anti-vortex ring 4 to move back and forth relative to the water pump assembly.

[0039] In some embodiments, a rotary power disk 8 is mounted on the linear slide rail 7. A first telescopic mechanism 5 is mounted and fixed on the rotary power disk 8. A controller is electrically connected to the rotary power disk 8 and is used to drive the rotary power disk 8 to rotate, thereby causing the first telescopic mechanism 5 to rotate within a preset range. This rotary power disk 8 is prior art and will not be described in detail here.

[0040] In some embodiments, the second telescopic mechanism 6 includes an electrically operated telescopic rod. A controller and the electric telescopic rod are electrically connected. A power motor 10 is mounted at the end of the electric telescopic rod and connected to the anti-vortex ring 4.
