[0001] The utility model relates to the technical field of water turbines, in particular to a high-efficiency and durable water turbine specially used for cooling towers. Background Art

[0002] Cooling towers are common industrial equipment used to reduce heat generated by factories, power plants, air conditioning systems, and other equipment. They utilize a water circulation system to release heated water through a radiator or evaporator into the air, dissipating heat during the heat exchange process and achieving the desired temperature reduction. A hydraulic turbine is a device that converts water energy into mechanical energy. The force or pressure of the water flow drives the impeller, which in turn drives a generator or other mechanical equipment. Widely used in hydropower stations, pumping stations, wind turbines, and other locations, hydraulic turbines are highly efficient, clean energy devices.

[0003] In the prior art, during the continuous use of cooling tower turbines, water is concentrated and pressurized, impacting the internal blades. This causes the internal pressure port of the turbine to be subjected to the continuous flow impact of the water flow, causing wear, reducing the water flow's pressurization effect, and affecting the performance of the turbine. Therefore, the present application designs a high-efficiency and durable cooling tower-specific water turbine. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that during the continuous use of the cooling tower turbine, water will be concentratedly diverted and pressurized to impact the internal blades, resulting in the internal pressurization port of the turbine being subjected to the continuous flow impact of the water flow, causing wear, reducing the pressurization effect of the water flow, and affecting the use effect of the turbine. The utility model proposes a high-efficiency and durable cooling tower special turbine.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The cam is provided with an axial wall of the water turbine housing, and an impeller is fixedly mounted on the axial wall of the water turbine housing. The axial wall of the water turbine housing extends to the outside of the water turbine housing and is fixedly connected to a connecting plate. A plurality of blades are fixedly connected around the edge of the connecting plate. A water inlet is provided on the inner wall of the water turbine housing. A plurality of openings are provided around the inner wall of the water turbine housing. A boosting retaining ring is fixedly connected to the inner wall of the water turbine housing at the opening. A boosting hole is provided on the inner wall of the boosting retaining ring. The inner wall of the boosting retaining ring at the boosting hole is set as an arc surface. A spring is fixedly connected to the side wall of the boosting retaining ring. The end of the spring facing away from the boosting retaining ring is fixedly connected to a movable retaining ring. A connecting baffle is fixedly connected to the inner wall of the water turbine housing at the boosting port. A sealing plug is fixedly connected to the side wall of the connecting baffle, and the sealing plug extends to the inner wall of the movable retaining ring.

[0007] Preferably, a connecting strip is fixedly connected to the side wall of the turbine housing, a first bolt is threadedly connected to the inner wall of the connecting strip, and a connecting end cover is fixedly connected to the water inlet of the turbine housing.

[0008] Preferably, the connections between the plurality of blades and the connecting disc are simultaneously threadedly connected with a second bolt.

[0009] Preferably, the turbine housing is configured as a volute structure, and a protective rubber strip is fixedly connected to the connection between the turbine housing and the connecting strip.

[0010] Compared with the existing technology, the utility model provides a high-efficiency and durable water turbine for cooling towers, which has the following beneficial effects:

[0011] 1. This efficient and durable cooling tower special turbine drives the impeller to rotate by water flowing through the water inlet into the interior of the turbine housing. The rotation of the impeller drives the rotation of the shaft, and the rotation of the shaft drives the connection plate and blades to rotate, so that the blades outside the turbine can rotate normally and continuously to ensure the use effect. The water flow can enter the interior of the turbine housing through the boost hole to drive the impeller, which can reduce the wear caused by the continuous flow of high-pressure water through the water inlet.

[0012] 2. This efficient and durable water turbine specially designed for cooling towers, when the water pressure is sufficient, the water will push the movable baffle to move and the spring will be compressed, so that the high-pressure water will flow through the gap between the sealing plug and the movable baffle ring and the booster baffle ring to the inside of the turbine housing, so that the high-pressure water diversion will transmit the impeller.

[0013] 3. This efficient and durable cooling tower special turbine can prevent low-pressure water from flowing into the turbine housing through the boost hole when the water pressure is insufficient, thereby preventing the transmission effect on the impeller. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-4 A high-efficiency and durable water turbine specially designed for cooling towers comprises a water turbine casing 1, wherein a rotating shaft 6 is rotatably connected to the interior of the water turbine casing 1, an impeller 7 is fixedly sleeved on the shaft wall of the rotating shaft 6, the shaft wall of the rotating shaft 6 extends to the outside of the water turbine casing 1 and is fixedly connected to a connecting disk 8, a plurality of blades 9 are fixedly connected around the edge of the connecting disk 8, a water inlet is provided on the inner wall of the water turbine casing 1, a plurality of openings are provided around the inner wall of the water turbine casing 1, a boosting retaining ring 11 is fixedly connected to the inside of the opening of the water turbine casing 1, a boosting hole is provided on the inner wall of the boosting retaining ring 11, and the inner wall of the boosting retaining ring 11 located at the boosting hole is set to an arc surface.

[0021] A connecting strip 3 is fixedly connected to the side wall of the turbine housing 1, and a first bolt 4 is threadedly connected to the inner wall of the connecting strip 3. A connecting end cover 5 is fixedly connected to the water inlet of the turbine housing 1, and a second bolt 10 is threadedly connected to the connection between multiple blades 9 and the connecting plate 8. The turbine housing 1 is configured as a volute structure.

[0022] During use, water is poured into the interior of the turbine casing 1 along the water inlet of the turbine casing 1. The water pressure can be increased by guiding the water through the volute structure inside the turbine casing 1. The water flows through the water inlet into the interior of the turbine casing 1 to drive the impeller 7 to rotate. The rotation of the impeller 7 can drive the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 can drive the connecting disk 8 and the blades 9 to rotate, so that the blades 9 outside the turbine can rotate normally and continuously, which can ensure the use effect. In order to prevent the water flow from causing wear to the water inlet after continuous use, the high-pressure water flow can enter the interior of the turbine casing 1 through the boosting hole to drive the impeller 7, which can reduce the wear caused by the continuous flow of high-pressure water through the water inlet. The second bolt 10 can make the blades 9 stably fixed inside the connecting disk 8.

[0023] In order to prevent the water pressure from being insufficient when passing through the pressure-boosting hole, Figure 1-4As shown, a spring 12 is fixedly connected to the side wall of the boosting retaining ring 11, and a movable retaining ring 13 is fixedly connected to the end of the spring 12 facing away from the boosting retaining ring 11. A connecting baffle 14 is fixedly connected to the inner wall of the turbine housing 1 at the boosting port, and a sealing plug 15 is fixedly connected to the side wall of the connecting baffle 14. The sealing plug 15 extends to the inner wall of the movable retaining ring 13, and a protective rubber strip 2 is fixedly connected to the connection between the turbine housing 1 and the connecting strip 3.

[0024] When the water pressure is sufficient, the water will push the movable retaining ring 13 to move and the spring 12 will be compressed, so that the high-pressure water flow can flow through the gap between the sealing plug 15 and the movable retaining ring 13 and the boosting retaining ring 11 to the inside of the turbine housing 1, so that the high-pressure water can be diverted to transmit the impeller 7.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
