Description

Technical Field

[0001] This invention relates to the field of submersible mixers, and in particular to a positioning device for a submersible mixer. Background Technology

[0002] Submersible mixers, also known as submersible propellers, are used in wastewater treatment plant processes to propel and agitate wastewater containing suspended solids, thin slurry, and industrial process liquids. They create water flow, enhance mixing, and prevent sludge sedimentation, making them crucial equipment in municipal and industrial wastewater treatment processes. Due to their underwater operation, corrosion resistance and underwater positioning of submersible mixers present significant technical challenges.

[0003] Currently, most submersible mixers are positioned by workers using winches to directly lower the mixer to the bottom of the water. While this method is low-cost, it faces many problems such as unstable lifting and positioning. Another method involves using a lifting platform in conjunction with large ground control points to achieve the submersible mixer's descent and positioning. This requires a large number of mechanical devices. Although the descent stability and positioning accuracy are high, the cost and maintenance expenses are extremely high, making it difficult to use and popularize in various working environments. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this section, the abstract and title of the invention. Such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] In view of the problems of not being able to balance costs, maintenance expenses, and diving stability and positioning accuracy in the above and / or existing technologies, this invention is proposed.

[0006] Therefore, the technical problem to be solved by the present invention is to improve the sinking stability and positioning accuracy of the submersible mixer while minimizing the required mechanical devices.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a submersible mixer positioning device, comprising a mixer, including a machine body shell, a connecting column provided on the machine body shell, and an adjustment component fixedly connected to the machine body shell through the connecting column;

[0008] The adjustment component includes a fixed rail, the inner sidewall of which is fixedly connected to one end of the connecting column. One end of the fixed rail is provided with a first ring, and the other end is symmetrically provided with a second ring. The ring is fitted inside the first ring and the second ring. The ring is fixedly connected to an expansion plate by a connecting rod.

[0009] The positioning platform includes a funnel opening, and the frustum formed by the funnel opening includes a generatrix D1 on the side of the frustum. The angle α formed by the generatrix D1 on the side of the frustum and the central axis D2 of the expansion plate on the same side pointing towards the opening.

[0010] In a preferred embodiment of the submersible mixer positioning device of the present invention, the first and second ring components are both arranged at equal intervals along the fixed railing.

[0011] In a preferred embodiment of the submersible mixer positioning device of the present invention, the first ring member has an opening on one side, and the width of the opening is the same as the width of the connecting rod.

[0012] In a preferred embodiment of the submersible mixer positioning device of the present invention, the outer wall of the fixed rail is provided with a limiting spring, and the coaxial lines of the limiting spring and the connecting rod are both in the same plane.

[0017] In a preferred embodiment of the submersible mixer positioning device of the present invention, a gripping suction cup is fixedly connected to the outer wall of the sinking cavity.

[0018] In a preferred embodiment of the submersible mixer positioning device of the present invention, four gripping suction cups are evenly spaced along the outer wall of the sinking cavity.

[0019] The beneficial effects of this invention are as follows: By using an underwater corrosion-resistant positioning device in conjunction with an adjustment component for fixing the submersible mixer, a highly efficient underwater working efficiency is achieved.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0031] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0032] Example 1

[0033] Reference Figures 1-5 This embodiment provides a submersible mixer positioning device, including a mixer 100, which is the submersible mixer body, including a machine shell 101. Four connecting columns 102 are provided around the machine shell 101. The four connecting columns 102 are parallel to each other. An adjustment component 200 is fixedly connected to the machine shell 101 through the connecting columns 102.

[0034] Furthermore, the adjustment component 200 is used to position and adjust the mixer when it contacts the positioning platform 300. It includes a fixing rail 201, one end of the connecting column 102 is connected to the outer shell 101 of the machine body, and the inner side wall of the fixing rail 201 is fixedly connected to one end of the connecting column 102, thereby fixing the mixer 100 and the adjustment component 200. The fixing rail 201 has a first set of rings 201a on the upper end and a second set of rings 201b symmetrically on the lower end. The set of rings are paired up and down. The ring 202 is fitted inside the first set of rings 201a and the second set of rings 201b. Each ring 202 is fixed and limited by a set of rings, namely the upper and lower sets of rings. The ring 202 is fixedly connected to the expansion plate 204 through the connecting rod 203.

[0035] Furthermore, the positioning platform 300 includes a funnel opening 301, which is similar to an inverted frustum. The frustum formed by the funnel opening 301 includes a generatrix D1 on the side of the frustum. The angle α formed by the generatrix D1 on the side of the frustum and the central axis D2 of the expansion plate 204 on the same side pointing to the opening is 90° < α < 143°. The expansion plate 204 will rotate with the ring 202 around the side of the fixed rail 201. Due to the limitation of the second set of rings 201b, the expansion plate 204 can only rotate downward to a position of 53° with the fixed rail 201.

[0036] Furthermore, to ensure that the expansion plate 204 rotates upward due to inertia when it contacts the funnel opening 301, the angle between the plane of the expansion plate 204 and the arc tangent of the funnel opening 301 when the expansion plate 204 contacts the funnel opening 301 must be greater than 90°. This angle cannot be too large. If the expansion plate 204 rotates to be parallel to the fixed railing 201, it will affect the accuracy of the coaxial positioning adjustment of the positioning platform 300 to the mixer during the submersion. Therefore, this angle is also less than 90° + 53° = 143° (that is, the angle α 90° < α < 143° formed by the generatrix D1 of the side of the frustum and the central axis D2 of the expansion plate 204 on the same side pointing to the opening).

[0037] Furthermore, the entire positioning platform 300, the outer shell 101, and the adjustment components 200 are all coated with asphalt mastic, which can effectively prevent water erosion and wear caused by water flow impact, while ensuring the flexibility and rapid drying effect of each component underwater.

[0038] Example 2

[0039] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that: the first set of rings 201a and the second set of rings 201b are both arranged evenly and equidistantly along the fixed rail 201. The first set of rings 201a has an opening 201a-1 on one side, the width of which is the same as the width of the connecting rod 203. The purpose of the opening 201a-1 is to allow the expansion plate 204 to rotate upwards without being obstructed by the first set of rings 201a, thus allowing it to pass through the opening 201a-1. Furthermore, both sets of rings are coated with asphalt mastic, providing high flexibility so that when the first set of rings 201a needs maintenance, the opening 201a-1 can be opened directly to remove the ring 202 without damage. When underwater operation is not required, the drying time of the components is also relatively short, allowing for continuous use.

[0040] Furthermore, the outer wall of the fixed railing 201 is provided with a limiting spring 205. The limiting spring 205 is also coated with asphalt mastic to ensure flexibility and water resistance. The coaxial lines of the limiting spring 205 and the connecting rod 203 are on the same plane. During the underwater submersion process, the expansion plate 204 will inevitably move slightly upward automatically under the action of buoyancy. The working environment of the submersible mixer is a biological tank, which is not deep and the buoyancy is not very strong. Therefore, when the expansion plate 204 rotates upward... When the connecting rod 203 encounters the limiting spring 205, it will be limited and unable to exceed the limited angle. During the process of entering the cavity, the expansion plate 204 needs to break through the limit and tend to fit with the outer shell 101. Therefore, there is a passage space between the two springs contained in the limiting spring 205. With a little force, the operator can pass the connecting rod 203 through the space between the springs, thereby breaking through the limit of the limiting spring 205, allowing the expansion plate 204 to rotate to a vertical state and enter the sinking cavity 302.

[0041] Furthermore, every two adjacent rings 202 are fixedly connected to an expansion plate 204 via a connecting rod 203. Four expansion plates 204 are arranged along the circumference of the outer casing 101. Each expansion plate 204 is equipped with a pulley 204a, with three pulleys on each side. The outer casing 101 is provided with sheet metal parts 103, which are long rods required for connecting to the ground. Four sheet metal parts 103 are evenly spaced along the outer casing 101. The outer casing 101 is provided with a sealing port 104, which ensures that the mixer is not interfered with by different liquid layers during operation. The sealing port 104 is reinforcedly connected to the outer casing 101 with bolts 104a.

[0042] Example 3

[0043] Reference Figures 1-7 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, and differs from the previous embodiment in that: one end of the funnel opening 301 is connected to the sinking cavity 302, which is the position to be dropped into after the mixer 100 is positioned. The sinking cavity 302 is provided with a through hole 302a, which is used for the mixer 100 to pass through. A gripping suction cup 303 is fixedly connected to the outer wall of the sinking cavity 302, and four gripping suction cups 303 are evenly and equidistantly arranged along the outer wall of the sinking cavity 302.

[0044] Workflow of this invention:

[0045] ① After the expansion plate 204 has been completed and the angle has been defined, the ground staff will use a rod-shaped connecting tool to connect it to the sheet metal part 103 of the mixer. Then the mixer 100 will be placed in the water to submerge. Even if a certain amount of positional displacement occurs, it can still touch the arc surface of the funnel opening 301 with a large area, thereby increasing the error tolerance of the positioning.

[0046] ② When the mixer 100 submerges, according to the specified angle, the pulley 204a on the expansion plate 204 will first touch the funnel opening 301. At this time, under the action of inertia, the pulley 204a will follow the expansion plate 204 and the ring 202, and under the limit of the two collar parts, it will make clockwise circular motion with the same side of the fixed rail 201 as the axis. At this time, the expansion plate 204 will approach the vertical state and slowly fit towards the mixer until it encounters the limiting spring 205 to limit the connecting rod 203.

[0047] ③ Under the action of external force from the staff, the connecting rod 203 breaks through the limit spring 205, and the expansion plate 204 can continue to rotate upward and tend to be vertical. After the mixer 100 enters the sinking chamber 302 through the funnel opening 301, it enters the through hole 302a. Under the inertia of the downward movement formed by the pulley 204a and the funnel opening 301 tending to be coaxial, it finds the accurate working position.
