Description

Technical Field

[0001] This utility model relates to the field of pump blade carrier technology, specifically a pump blade carrier with a quick-change module. Background Technology

[0002] Pump blade carriers are devices used to stabilize and fix pump blades, preventing them from being deformed or damaged by collisions or squeezing during rotation. They are usually designed according to the size, shape and weight of the blades, and are mostly made of metal frames or composite materials. Some carriers are equipped with buffer pads, positioning buckles and other structures to ensure that the blades are accurately aligned and placed stably. Pump blade carriers can usually replace blade modules. When it is necessary to adapt to pump blades of different specifications, it is not necessary to replace the entire carrier. You only need to replace the corresponding module according to the parameters of the new blade. For example, for blades with different curvature, replace with a module with matching grooves. For blades with different thicknesses, replace with a module with corresponding limiting protrusions. However, when clamping the pump blade carrier to the module, it is often necessary to loosen the fixing bolts one by one, remove the old module, and then realign the mounting holes of the new module and tighten the bolts one by one to complete the fixation. The whole process is cumbersome and not only consumes a lot of time, but repeated disassembly and tightening of bolts can also easily cause thread wear, affecting the stability of subsequent clamping. Therefore, in order to address the above problems, a pump blade carrier that can quickly replace the module is proposed. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-7 This utility model provides a technical solution: A pump blade carrier with quick-change modules includes a support base 1, a support plate 2, and a gasket ring 3. The support plate 2 is fixed to the upper end of the support base 1 by bolts. The gasket ring 3 and a limiting component 7 are sequentially fixed to the upper end of the support plate 2 by bolts. A flow guiding component 4 is installed between the support plate 2 and the limiting component 7. A rotating component 5 is rotatably installed between the flow guiding component 4 and the limiting component 7. The rotating component 5 includes a rotating frame 51. A rotating block 52 is welded to the upper end of the rotating frame 51. A rotating strip 53 is welded to one side of the rotating block 52. A fixing seat 54 is welded to the outer side of the rotating frame 51. An insertion hole 55 is opened on the inner side of the fixing seat 54. An inner support ring 56 is welded to one side of the rotating strip 53. The limiting component 7 includes a limiting ring 71. Multiple limiting strips 72 are welded to the inner side of the limiting ring 71. A pressure ring 73 is welded to one side of the limiting strip 72. A slot 74 is opened on the inner side of the limiting ring 71.

[0017] As a further implementation of this solution, the flow guiding component 4 includes a flow guiding disk 41. A first annular groove 42, a second annular groove 43, and a third annular groove 44 are formed inside the flow guiding disk 41. An insert 45 is inserted into the inner side of the flow guiding disk 41. The first annular groove 42, the second annular groove 43, and the third annular groove 44 have the same depth, and the ratio of their widths is 25:28:43. 42. The diameter ratio of the side of the second annular groove 43 and the third annular groove 44 closest to the iron insert 45 is 463:728:895. The first annular groove 42, the second annular groove 43 and the third annular groove 44 opened in the guide plate 41 can regulate the flow path of the fluid in the pump. The design of the opening width ratio of the first annular groove 42, the second annular groove 43 and the third annular groove 44 is 25:28:43, forming a gradually expanding flow channel, gradually reducing the fluid velocity, and avoiding turbulence and energy loss caused by sudden diffusion. As a further implementation of this solution, the insert 45 is inserted into the inner support ring 56 and the pressure ring 73. There is a gap between the outer side of the insert 45 and the inner side of the inner support ring 56. The inner support ring 56 has the same shape as the pressure ring 73. The bottom end of the pressure ring 73 is attached to the upper end of the inner support ring 56. The design of the gap between the outer side of the insert 45 and the inner side of the inner support ring 56 allows it to expand freely in the axial direction when the temperature rises, and there is a gap in the radial direction to release deformation. After the end face of the pressure ring 73 and the inner support ring 56 are attached, a symmetrical axial limiting plane can be formed. As a further implementation of this solution, a connecting component 6 is installed in the socket 55. The connecting component 6 includes a plug block 61, a positioning pin 62 inserted in the plug block 61, and a pin 63 inserted in the plug block 61. The bottom end face of the plug block 61 is in contact with the upper end face of the fixed seat 54. The positioning pin 62 passes through both the fixed seat 54 and the plug block 61. The plug block 61 and the fixed seat 54 are in contact to provide an axial reference. The positioning pin 62 passes through both the fixed seat 54 and the plug block 61, locking the radial, tangential, and angular positions at once. As a further implementation of this solution, the upper end of the limiting ring 71 is rotatably mounted with a transmission component 8 by bolts. The inner side of the rotating handle 81 is provided with a mounting hole 82 and a pin hole 83. The bottom end of the rotating handle 81 is provided with a notch 84. A pin 63 is inserted into the pin hole 83. One side of the notch 84 is arc-shaped. This design allows the rotating handle 81 to swing only within the designed angle. The arc-shaped setting on one side of the notch 84 can prevent the plug block 61 from being obstructed when it moves. As a further implementation of this solution, a rotating block 52 is slidably arranged in the slot 74. The thickness of the rotating bar 53 is half the thickness of the rotating block 52. The bottom surface of the rotating bar 53 and the bottom surface of the rotating block 52 are on the same horizontal plane. The number of rotating blocks 52 corresponds to the number of limiting bars 72. The rotating blocks 52 and the limiting bars 72 are staggered and arranged in a circular array. The thickness of the rotating bar 53 is halved to form a natural step, which facilitates the positioning of the blade module. The staggered distribution of the rotating blocks 52 and the limiting bars 72 can distribute the torque evenly, reduce stress concentration, and thus better clamp the blade module.

[0018] Workflow: During installation, the support plate 2 is bolted onto the support base 1, then the gasket ring 3 is placed on top of the support plate 2. The flow guiding assembly 4 is then installed onto the support plate 2, ensuring that the central axis of the insert 45 and the central axis of the support plate 2 are on the same vertical line. Next, the rotating assembly 5 is fitted over the insert 45 from above, so that the fixing seat 54 fixed on one side of the rotating frame 51 is positioned between the groove on the support plate 2 and the notch of the gasket ring 3. Finally, the limiting assembly 7 is used to press down the gasket ring 3, thus limiting the flow. After aligning the screw holes on parts 7, gasket ring 3, and support plate 2, fix the three together with bolts. Then place the plug block 61 on the fixed base 54, and insert the positioning pin 62 through the plug block 61 into the plug hole 55, so that the fixed base 54 and the rotating block 52 are connected. Fix the rotating handle 81 on the limit ring 71 by passing the bolt through the mounting hole 82. After rotating and adjusting the rotating handle 81, pass the pin 63 through the pin hole 83 and the plug block 61, so that the plug block 61 and the rotating handle 81 are connected. When replacing the blade module, the handle 81 is turned so that it rotates and drives the insertion block 61 to move through the pin 63 inserted in the pin hole 83. As the insertion block 61 moves, the arc-shaped design on one side of the notch 84 prevents its movement from being obstructed, allowing it to better drive the fixed base 54 via the positioning pin 62. This causes the rotating frame 51, fixed to the fixed base 54, to rotate. When the rotating frame 51 rotates, the rotating block 52 welded to the upper end of the rotating frame 51 slides in the slot 74, simultaneously driving the fixed rotating strip 53 to move, thereby changing the relative positions of the rotating strip 53 and the limiting strip 72. The pump blade module is clamped and released according to its position, thus facilitating module replacement. Throughout the process, the guide plate 41 supports the inner support ring 56 at its lower end, allowing the inner support ring 56 to adhere to the pressure ring 73 and rotate stably around the inlaid iron part 45. The first annular groove 42, the second annular groove 43, and the third annular groove 44 opened in the guide plate 41 can regulate the flow path of the fluid in the pump, allowing the fluid to enter the different flow channels of the pump evenly and orderly, avoiding fluid turbulence and impact, improving the pump's working efficiency and stability, and reducing noise, vibration, and energy loss caused by irregular fluid flow.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
