Description

Technical Field

[0001] This utility model relates to the field of energy and power engineering technology, and in particular to a circulating water energy efficiency conversion device. Background Technology

[0002] A circulating water energy conversion device is a type of equipment that captures and converts energy by utilizing the kinetic energy, potential energy, or pressure difference of the flowing medium (such as water) in a circulating water system through mechanical structures such as impellers and turbines. Its core function is to convert the surplus energy of circulating water, which is not fully utilized during transportation and cooling processes, into mechanical or electrical energy, thereby improving the system's energy efficiency. This device is widely used in industrial circulating water systems, central air conditioning cooling water systems, and water conservancy circulation systems, possessing both energy-saving and environmentally friendly attributes, and is one of the key pieces of equipment for achieving cascaded energy utilization.

[0003] Currently, in industrial production, energy conversion is often achieved through circulating water. The circulating water drives the impeller to rotate, thereby generating electricity. However, the diameter of the impeller in existing equipment is mostly fixed. When the circulating water flow is small, the contact area between the water flow and the impeller is too small, which can easily lead to the impeller rotating too slowly or stopping, thus failing to achieve effective energy conversion.

[0004] Therefore, we propose a circulating water energy efficiency conversion device to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A circulating water energy efficiency conversion device includes an energy efficiency conversion pipe body, a waterproof shell fixedly installed on one side of the energy efficiency conversion pipe body, a transmission hole opened on one side of the energy efficiency conversion pipe body, a sealing ring fixedly installed on the inner side of the transmission hole, and a transmission shaft rotatably installed on the inner side of the sealing ring; a hollow turntable is fixedly sleeved on the transmission shaft, and six guide grooves are opened on one side of the hollow turntable.

[0007] Specifically, flanges are fixedly installed at both ends of the main body of the energy efficiency conversion pipeline to facilitate connection with the corresponding circulation pipeline.

[0008] Specifically, a generator is provided on one side of the main body of the energy conversion pipeline, and a coupling is fixedly installed at one end of the drive shaft. The coupling is fixedly connected to the rotor of the generator, so that the rotor of the generator can be driven to rotate through the drive shaft, thereby generating electricity.

[0009] Specifically, an observation head is fixedly installed on one side of the main body of the energy efficiency conversion pipeline, which can observe the flow rate of the circulating water inside the main body of the energy efficiency conversion pipeline.

[0010] Specifically, a filter screen is detachably installed on the inner side of the main body of the energy efficiency conversion pipeline, which can filter impurities and prevent impurities from affecting the equipment.

[0011] Specifically, the waterproof outer shell has a waterproof chamber inside, and a waterproof cylinder is fixedly installed on the bottom inner wall of the waterproof chamber. A pressing shaft is fixedly installed on the piston end of the waterproof cylinder. The pressing shaft extends into the inner side of the energy efficiency conversion pipeline body and is slidably sleeved on the transmission shaft.

[0012] Specifically, flow vanes are slidably installed on the inner side of each of the six guide slots, and a linkage slot is provided on one side of each of the six flow vanes to facilitate the movement of the flow vanes via the linkage bar.

[0013] Specifically, a pressing cone is slidably sleeved on the drive shaft, one side of the pressing cone is rotatably connected to one end of the pressing shaft, and multiple linkage bars are fixedly installed on the outer side of the pressing cone, with each linkage bar being adapted to a corresponding linkage groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting the extrusion cone and sliding blades, the position of the blades can be adjusted by observing the flow rate of the circulating water in the pipeline. When the flow rate of the circulating water fluctuates, adjusting the radial position of the blades can change the flow receiving area, ensuring that the blades efficiently capture water flow energy, avoiding overload when the flow rate is too large or sudden drop in efficiency when the flow rate is too small, and can quickly change the output power of the device to achieve a smooth transition and protect the equipment from impact.

[0021] Reference Figure 1-5 A circulating water energy efficiency conversion device includes an energy efficiency conversion pipe body 1, a waterproof shell 7 fixedly installed on one side of the energy efficiency conversion pipe body 1, a transmission hole opened on one side of the energy efficiency conversion pipe body 1, a sealing ring 11 fixedly installed on the inner side of the transmission hole, and a transmission shaft 10 rotatably installed on the inner side of the sealing ring 11; a hollow turntable 12 is fixedly sleeved on the transmission shaft 10, and six guide grooves are opened on one side of the hollow turntable 12.

[0022] In this embodiment, flanges 2 are fixedly installed at both ends of the energy efficiency conversion pipeline body 1 to facilitate connection with the corresponding circulation pipeline.

[0023] In this embodiment, a generator 3 is provided on one side of the main body 1 of the energy efficiency conversion pipeline, and a coupling 4 is fixedly installed at one end of the drive shaft 10. The coupling 4 is fixedly connected to the rotor of the generator 3, so that the rotor of the generator 3 can be driven to rotate through the drive shaft 10 to generate electricity.

[0024] In this embodiment, an observation head 5 is fixedly installed on one side of the energy efficiency conversion pipe body 1, which can observe the flow rate of the circulating water inside the energy efficiency conversion pipe body 1.

[0025] In this embodiment, a filter screen 6 is detachably installed on the inner side of the energy efficiency conversion pipeline body 1, which can filter impurities and prevent impurities from affecting the equipment.

[0026] In this embodiment, a waterproof chamber is provided inside the waterproof outer shell 7. A waterproof cylinder 8 is fixedly installed on the bottom inner wall of the waterproof chamber. A pressing shaft 9 is fixedly installed on the piston end of the waterproof cylinder 8. The pressing shaft 9 extends into the inner side of the energy efficiency conversion pipeline body 1 and is slidably sleeved on the transmission shaft 10.

[0027] In this embodiment, flow vanes 13 are slidably installed on the inner side of each of the six guide grooves, and a linkage groove 16 is provided on one side of each of the six flow vanes 13 to facilitate the movement of the flow vanes 13 by means of the linkage bar 15.

[0028] In this embodiment, a compression cone 14 is slidably sleeved on the drive shaft 10. One side of the compression cone 14 is rotatably connected to one end of the compression shaft 9. Multiple linkage bars 15 are fixedly installed on the outer side of the compression cone 14, and the multiple linkage bars 15 are respectively adapted to the corresponding linkage grooves 16.

[0029] Working Principle: During the energy conversion of circulating water, the operator connects the main body 1 of the energy conversion pipe to the corresponding circulating pipe via flange 2. The circulating water then flows, and its kinetic, potential, and pressure energy acts on the flow vanes 13, driving multiple flow vanes 13 to rotate around the axis of the drive shaft 10. This converts the fluid energy of the water flow into the mechanical energy of the drive shaft 10. The rotation of the drive shaft 10 is transmitted to the rotor of the generator 3 via coupling 4. When the rotor of the generator 3 rotates, it cuts the magnetic field around the stator windings, generating an induced electromotive force in the stator windings according to the law of electromagnetic induction. After closing the circuit, electrical energy is output. The operator observes this through head 5. Observe the circulating water flow inside the main body 1 of the energy efficiency conversion pipeline. When the circulating water flow decreases, the staff activates the waterproof cylinder 8. The activation of the waterproof cylinder 8 drives the extrusion shaft 9 to move. The movement of the extrusion shaft 9 drives the extrusion cone 14 to move. The movement of the extrusion cone 14 extrudes multiple flow vanes 13. Multiple flow vanes 13 are slidably installed on the inner side of the corresponding guide groove. Therefore, when multiple flow vanes 13 are extruded, they will move radially. Multiple flow vanes 13 move closer to the inner wall of the main body 1 of the energy efficiency conversion pipeline, so that they can better contact the circulating water, expand the flow area, and thus ensure that the vanes efficiently capture water flow energy and increase the stability of the equipment.

[0030] The technological advancement of this invention compared to the prior art is that the position of the flow vane 13 can be adjusted by observing the flow rate of the circulating water in the pipeline. When the flow rate of the circulating water fluctuates, adjusting the radial position of the flow vane 13 can change the flow receiving area, ensuring that the vane efficiently captures the energy of the water flow, avoiding overload when the flow rate is too high or a sudden drop in efficiency when the flow rate is too low, and can quickly change the output power of the device to achieve a smooth transition and protect the equipment from impact.
