Description

Technical Field

[0001] This application relates to the field of flow promoter technology, and more specifically, to a flow promoter lifting ring. Background Technology

[0002] Lifting is required during routine maintenance and troubleshooting of the propeller. Lifting lugs are fixedly connected to the propeller motor, and shackles and chains are installed on the lugs to assist in lifting the propeller.

[0003] During maintenance, the impact of water flow and the slight vibration and friction generated by the propeller's rotation can cause wear on the lifting chain, shackles, or lifting lugs. This wear can easily lead to breakage of the chain, shackles, or lifting rings during retrieval and lifting, causing the propeller to fall. Due to the small hole spacing of the lifting lugs, retrieving the propeller using retrieval hooks or similar equipment after a fall is extremely difficult. Therefore, divers are required to descend into the pool for retrieval. This method is inefficient and carries a high risk due to the limited space.

[0004] In summary, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.

[0027] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] See Figure 1 and Figure 4 This application provides a jet mixer lifting ring, comprising:

[0031] The first connecting seat 4 is fixedly connected to the bottom of the propeller 1, and the first connecting rod 2 is provided on the top of the first connecting seat 4;

[0032] The second connecting seat 5 is fixedly connected to the pusher 1 after a predetermined distance is set between it and the first connecting seat 4. The top of the second connecting seat 5 is provided with a second connecting rod 3.

[0033] The top of the first link 2 is fixedly connected to the top of the second link 3. The connection between the first link 2 and the second link 3 forms a hook angle, which is used to connect with the salvage anchor hook 8 or the lifting shackle 9.

[0034] like Figure 4 and Figure 5As shown, this application utilizes the stability of a triangle to ensure the structural strength of the hook-lifting angle by setting the hook-lifting angle. Furthermore, it allows the lifting shackle 9 or the retrieval anchor 8 to slide along the first connecting rod 2 or the second connecting rod 3 to the hook-lifting angle, ensuring that it will not move during the lifting or retrieval process. This further guarantees the stability of the retrieval or lifting process, enabling the safe and smooth lifting or retrieval of the propeller 1.

[0035] In one feasible embodiment, the angles of the first link 2 and the second link 3 are adjustable, and the angles are adjusted according to the center of gravity position of the propeller 1 so that the apex of the hook angle and the center of gravity of the propeller 1 are on the same straight line in the vertical direction.

[0036] In one feasible embodiment, the first connecting rod 2 is arranged vertically, and a third connecting rod 6 is provided between the second connecting rod 3 and the second connecting seat 5. The third connecting rod 6 is also arranged vertically, and the second connecting rod 3 is inclined so that a hook angle is formed between the second connecting rod and the first connecting rod 2 or the third connecting rod 6, and the hook angle is an acute angle. The retrieval hook 8 can slide along the inclined second connecting rod 3 and quickly slide to the hook angle, maintaining the retrieval hook 8 stably at the hook angle during the lifting process, ensuring the stability of the retrieval and lifting process. By setting the third connecting rod 6 and the first connecting rod 2, the vertical length of this application is increased, thereby increasing the target area of ​​the retrieval hook 8, increasing the probability of the hook catching the lifting ring during retrieval, and reducing the difficulty of retrieval.

[0037] It should be noted that the tilt angle of the second link 3 is 45°-80°, so that the included angle between the first link 2 and the second link 3 is 45°-80°, avoiding an excessively large angle that would cause the salvage hook 8 to slide rapidly and significantly on the second link 3.

[0038] In one feasible approach, such as Figure 3 As shown, a fourth link 7 is horizontally arranged between the first link 2 and the second link 3. The length of the fourth link 7 is the sliding length of the salvage anchor hook 8. The sliding distance of the salvage anchor hook 8 is limited by the fourth link 7. This is suitable for situations where two or more sets of salvage anchor hooks 8 are set. The setting of the fourth link 7 increases the fixing space of the salvage anchor hook 8.

[0039] In one feasible approach, such as Figures 1 to 3 As shown, fastening holes are provided on the first connecting seat 4 and the second connecting seat 5. By installing fastening bolts in the fastening holes, the first connecting seat 4 and the second connecting seat 5 are respectively fixedly connected to the propeller 1.

[0040] Specifically, in this embodiment, after the fastening bolt is connected to the fastening hole, it is then connected and fixed to the original screw hole on the thruster 1 or the mounting hole of the motor bracket, ensuring a stable connection while avoiding the need for re-drilling.

[0041] In one feasible embodiment, two mounting holes are provided on the first connecting seat 4 and two mounting holes are provided on the second connecting seat 5 to enhance the stability of the connection with the propeller 1.

[0042] In one feasible approach, such as Figures 1 to 3 As shown, the hook corner is rounded to reduce collisions during the retrieval and lifting process and to avoid wear.

[0043] In one feasible embodiment, the first link 2, the second link 3, the third link 6, and the fourth link 7 are all made of 304 stainless steel to prevent rusting due to friction underwater, which would affect the structural strength.

[0044] It should be noted that this application involves the modification of the lifting and maintenance system for 310 Xylem submersible mixers and agitators in the second phase of the sludge treatment and wastewater upgrading project. These include 8 units in the anaerobic zone of the southwest biological reactor, 24 units in the anoxic zone of the southwest biological reactor, 32 units in the anaerobic zone of the south biological reactor, 96 units in the anoxic zone of the south biological reactor, 32 units in the anaerobic zone of the northwest biological reactor, 96 units in the anoxic zone of the northwest biological reactor, and 22 units in the sludge storage tank. The mixer lifting rings provided in this application enable safer and more convenient lifting of the equipment during maintenance, reducing maintenance costs, increasing construction safety, and providing flexibility and convenience during construction.

[0045] In summary, this application not only meets the lifting requirements but also increases the target area for retrieval, thereby reducing the difficulty of retrieval. The hook angle design utilizes the stability of a triangle to ensure the structural strength of the hook angle. Furthermore, the lifting shackle 9 or the retrieval anchor 8 can slide along the first link 2 or the second link 3 to the hook angle, ensuring no movement during the lifting or retrieval process, further guaranteeing the stability of the retrieval or lifting process, and enabling the safe and smooth lifting or retrieval of the propeller 1. This application features corrosion resistance, high strength, resistance to deformation, and a large span, increasing the target area of ​​the anchor hook. In the event of breakage of the lifting chain or shackle 9, the anchor hook can be used for rapid and stable retrieval, eliminating the need for divers to enter the pool, reducing costs, improving safety and work efficiency, lowering safety risks, and ensuring the normal operation of the wastewater treatment plant.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
