[0023] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following is in combination with specific embodiment, and referring to the drawing, the utility model is further detailed.

[0024] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the utility model should be understood as the usual meaning of the person skilled in the art to which the application belongs. The "first", "second" and similar words used in the application do not represent any order, quantity or importance, but are only used to distinguish different components.

"Up", "down", "left", "right" and the like are only used to represent the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0025] As described in the background, the generator lower baffle and the screen of the generator stator have a gap, therefore, a fluorine rubber strip is arranged at one end of the lower baffle close to the screen to block the gap. The screen has a hole, and the screen is installed on the generator stator by binding ropes soaked in epoxy resin passing through the hole. When the lower baffle is installed, the binding ropes soaked in epoxy resin protrude relative to the screen, forming a binding rope protrusion, which causes the fluorine rubber strip on the lower baffle to be unable to move to the correct position on the screen, and manual force is required to move the fluorine rubber strip to the correct position with tools such as wrenches and screwdrivers. The manual amount is large, which is not conducive to the installation efficiency of the lower baffle.

[0026] Therefore, the application provides an auxiliary installation tool for a generator lower baffle to avoid the binding rope protrusion on the screen affecting the movement of the fluorine rubber strip on the lower baffle to the correct position, so that the fluorine rubber strip can be smoothly moved to the correct position, thereby improving the installation efficiency of the lower baffle.

[0027] The following is described in detail through one or more specific embodiments.

[0028] In some embodiments, an auxiliary installation tool for a lower wind deflector 100 of a generator, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the lower wind deflector 100 is provided with a fluororubber strip 110 near one end of a generator stator 200, the inner periphery of the generator stator 200 is provided with a screen 210, and the screen 210 is provided with a plurality of binding protrusions 211 on one side near the fluororubber strip 110, the auxiliary installation tool comprises:

[0029] An arc-shaped abutting plate 300 is located on the side of the screen 210 provided with the binding protrusions 211 and covers the plurality of binding protrusions 211, and the side of the arc-shaped abutting plate 300 away from the screen 210 is a smooth surface, which is in contact with the fluororubber strip 110 when the lower wind deflector 100 moves up and down relative to the generator stator 200.

[0030] Specifically, the lower wind deflector 100 has a gap between the side near the screen 210 of the generator stator 200 and the screen 210 during installation, and the fluororubber strip 110 is located on the side of the lower wind deflector 100 near the screen 210 to block the gap and avoid affecting the windproof effect of the lower wind deflector 100. The free end of the fluororubber strip 110 is in contact with the screen 210 and moves up and down with the lower wind deflector 100 to move to the correct position in contact with the screen 210 to achieve the purpose of windproof.

[0031] The screen 210 and the generator stator 200 are connected by a binding rope, that is, the binding rope passes through the hole on the screen 210 and is connected with the generator stator 200 to make the screen 210 located on the generator stator 200. The binding rope forms a binding protrusion 211 on the side of the screen 210 near the fluororubber strip 110, which causes the screen 210 and the fluororubber strip 110 to be unable to smoothly move to the correct position on the screen 210 after contacting, affecting the correct use of the fluororubber strip 110.

[0032] The arc-shaped abutting plate 300 is used to be located between the screen 210 and the fluororubber strip 110, so as to avoid the direct contact between the binding rope protrusion 211 and the fluororubber strip 110, and affect the smooth movement of the fluororubber strip 110. The fluororubber strip 110 can move smoothly to the correct position on the smooth surface of the arc-shaped abutting plate 300, and the wear of the fluororubber strip 110 can be reduced, which is beneficial to the wind blocking effect of the lower wind deflector 100. After the installation of the lower wind deflector 100 is completed, the arc-shaped abutting plate 300 can be removed for the installation of the next lower wind deflector 100.

[0033] It should be noted that the arc-shaped abutting plate 300 is adapted to the curvature and radius of the screen 210, so as to be arranged in close contact with the screen 210, so as to cover the binding rope protrusion 211 on the screen 210. In addition, in order to ensure the strength of the arc-shaped abutting plate 300 and the smooth movement of the fluororubber strip 110, the thickness of the arc-shaped abutting plate 300 is 3-8 mm. If the thickness is too small, the binding rope protrusion 211 is likely to protrude relative to the arc-shaped abutting plate 300 during the movement of the fluororubber strip 110, which affects the smooth movement of the fluororubber strip 110. If the thickness is too large, it will occupy too much gap between the fluororubber strip 110 and the screen 210, which will make it difficult to remove the arc-shaped abutting plate 300, and affect the installation efficiency of the lower wind deflector 100.

[0034] Finally, the material of the arc-shaped abutting plate 300 is epoxy resin, which has the advantages of light weight and high strength, which is convenient for use of the arc-shaped abutting plate 300, and is conducive to improving the installation efficiency of the lower wind deflector 100.

[0035] In the embodiment, by arranging the arc-shaped abutting plate 300 to cover the binding rope protrusion 211 on the screen 210, when the lower wind deflector 100 drives the fluororubber strip 110 to move up and down, the fluororubber strip 110 moves in contact with the smooth surface of the arc-shaped abutting plate 300 to smoothly move to the correct position. Thus, the fluororubber strip 110 can move smoothly to the correct position on the screen 210 without the need for additional manual assistance, which is conducive to improving the smoothness of the movement of the lower wind deflector 100 and the fluororubber strip 110, and is conducive to improving the installation efficiency of the lower wind deflector 100.

[0036] In some embodiments, as shown in Figure 4 The arc-shaped abutting plate 300 includes an upper and lower main body segment 310 and a transition segment 320, the transition segment 320 is located at the bottom of the main body segment 310, and is lower than the bottom of the screen 210.

[0037] Specifically, the main body section 310 is used to cover the binding rope protrusion 211, and the transition section 320 is used to cover the bottom of the screen 210 and other areas of the bottom of the screen 210, so that the fluororubber strip 110 can move to the main body section 310 through the transition section 320, thereby reducing the blocking effect of the binding rope protrusion 211 on the movement of the fluororubber strip 110, so that the fluororubber strip 110 can move smoothly on the arc-shaped abutting plate 300 to the correct position, reducing the influence of the binding rope protrusion 211 on the fluororubber strip 110, thereby enabling the fluororubber strip 110 to move to the correct position with the lower windshield 100, and facilitating the improvement of the installation efficiency of the lower windshield 100.

[0038] In some embodiments, as shown in the drawings, the radius of the transition section 320 is greater than the radius of the main body section 310. Figure 4

[0039] Specifically, as the fluororubber strip 110 moves from low to high with the lower windshield 100, the transition section 320 is located at the bottom of the main body section 310, and the transition section 320 and the main body section 310 are both arc-shaped structures used to contact the fluororubber strip 110. The radius of the transition section 320 is set to be greater than the main body section 310, so that the distance between the fluororubber strip 110 and the arc-shaped abutting plate 300 changes from large to small, reducing the influence of the arc-shaped abutting plate 300 on the fluororubber strip 110 during movement, which can facilitate the contact between the fluororubber strip 110 and the transition section 320, and further facilitate the contact between the fluororubber strip 110 and the arc-shaped abutting plate 300.

[0040] In some embodiments, the auxiliary installation tool further comprises a connecting piece 400 located on the arc-shaped abutting plate 300 and used to detachably connect with the screen 210.

[0041] Specifically, the connecting piece 400 is used to detachably connect the arc-shaped abutting plate 300 with the screen 210, so that when the lower windshield 100 is installed, the arc-shaped abutting plate 300 is connected with the screen 210, so that the arc-shaped abutting plate 300 is stably arranged on the screen 210, which is conducive to the contact stability of the fluororubber strip 110 and the arc-shaped abutting plate 300, and further improves the practicability of the auxiliary installation tool.

[0042] In addition, after the installation of the lower windshield 100 is completed, the connecting piece 400 is detached from the screen 210 and removed to the ground, which facilitates the removal of the arc-shaped abutting plate 300 by the staff, so that the fluororubber strip 110 abuts against the screen 210, which is conducive to improving the practicability of the auxiliary installation tool.

[0043] ​In some embodiments, the connecting piece 400 comprises a negative pressure suction disc, which is located on one side of the arc-shaped abutting plate 300 close to the screen 210, and is used for negative pressure suction connection with the screen 210.

[0044] Specifically, the negative pressure suction disc can be connected with the screen 210 in negative pressure suction, which can not only ensure the stable connection between the arc-shaped abutting plate 300 and the screen 210, but also make the connection and disconnection between the arc-shaped abutting plate 300 and the screen 210 simple, so as to improve the installation and disassembly efficiency of the arc-shaped abutting plate 300, and further improve the installation efficiency of the lower wind deflector 100.

[0045] It should be noted that in order to ensure the uniform connection between the arc-shaped abutting plate 300 and the screen 210, and facilitate smooth contact between the arc-shaped abutting plate 300 and the fluorine rubber strip 110, a plurality of negative pressure suction discs are uniformly arranged on one side of the arc-shaped abutting plate 300 close to the screen 210.

[0046] In some embodiments, the connecting piece 400 comprises an upper hook and a lower hook, the upper hook is used for hanging connection with the top surface of the screen 210, and the lower hook is used for hanging connection with the bottom surface of the screen 210, and the upper hook and the lower hook are detachably connected with the arc-shaped abutting plate 300.

[0047] Specifically, the upper hook and the lower hook jointly limit the arc-shaped abutting plate 300, so that the arc-shaped abutting plate 300 is stably connected with the screen 210, and avoids moving with the fluorine rubber strip 110 during the up and down movement of the fluorine rubber strip 110, which is conducive to the contact between the fluorine rubber strip 110 and the arc-shaped abutting plate 300 and moving to the correct position.

[0048] In addition, the upper hook and the lower hook are detachably connected with the arc-shaped abutting plate 300, which can facilitate the removal of the upper hook and the lower hook when the arc-shaped abutting plate 300 is withdrawn, so as to avoid the influence of the connection between the upper hook and the lower hook and the screen 210 on the withdrawal of the arc-shaped abutting plate 300.

[0049] In this embodiment, the upper hook and the lower hook can play a role in stable connection when the arc-shaped abutting plate 300 needs to be stably connected with the screen 210, and can be detached from the arc-shaped abutting plate 300 when the arc-shaped abutting plate 300 needs to be connected with the screen 210 and withdrawn from the fluorine rubber and the screen 210, which is convenient for the withdrawal of the arc-shaped abutting plate 300 and is conducive to improving the practicability of the auxiliary installation tool.

[0050] In some embodiments, a plurality of upper hooks and a plurality of lower hooks are provided, and the lower hooks are provided in one-to-one correspondence with the upper hooks.

[0051] Specifically, the plurality of upper hooks and the plurality of lower hooks can make the connection between the arc-shaped abutting plate 300 and the screen 210 more stable and uniform, so that the spacing between the arc-shaped abutting plate 300 and the screen 210 is uniform, which is conducive to the flatness of the side of the arc-shaped abutting plate 300 close to the fluororubber strip 110, and is conducive to the stable and smooth movement of the fluororubber strip 110 on the arc-shaped abutting plate 300.

[0052] In some embodiments, the upper hooks and the lower hooks are detachably connected to the arc-shaped abutting plate 300 by negative pressure suction cups.

[0053] Specifically, the upper hooks and the lower hooks are detachably connected to the arc-shaped abutting plate 300 by negative pressure suction cups, which can simplify the connection between the upper hooks and the lower hooks and the arc-shaped abutting plate 300 without affecting the connection strength, and is conducive to improving the disassembly and connection efficiency of the upper hooks and the lower hooks and the arc-shaped abutting plate 300, thereby improving the installation efficiency of the lower wind shield 100 and the practicability of the auxiliary installation tool.

[0054] In some embodiments, as shown in Figure 5 The upper hooks and the lower hooks each include a horizontally connected horizontal segment 410 and a vertical segment 420, and the vertical segment 420 rotates around the horizontal segment 410.

[0055] Specifically, the vertical segment 420 rotates around the horizontal segment 410, which can rotate the vertical segment 420 to contact the side of the screen 210 away from the arc-shaped abutting plate 300 when the upper hooks and the lower hooks need to be hung with the screen 210, so as to realize the hanging, and rotate the vertical segment 420 to not contact the screen 210 when the upper hooks and the lower hooks need to be unhung with the screen 210, so as to facilitate the disassembly of the upper hooks and the lower hooks from the arc-shaped abutting plate 300.

[0056] In addition, the axial rotation of the vertical section 420 around the horizontal section 410 can ensure the stability of the vertical section 420 when being rotated to be connected with the screen 210, avoid the rotation of the vertical section 420 to be not contacted with the screen 210 under the action of the vertical force applied by the arc-shaped abutting plate 300 to the vertical section 420 when the arc-shaped abutting plate 300 moves up and down on the fluororubber strip 110 under the action of gravity, so that the arc-shaped abutting plate 300 is stably connected with the screen 210, and the practicability of the auxiliary installation tool is improved.

[0057] In some embodiments, the arc-shaped abutting plate 300 is smoothly arranged on one side close to the screen 210.

[0058] Specifically, the arc-shaped abutting plate 300 is smoothly arranged on one side close to the screen 210 and one side close to the fluororubber strip 110, which can reduce the friction between the arc-shaped abutting plate 300 and the fluororubber strip 110 and the screen 210, and further reduce the abrasion of the fluororubber strip 110 and the screen 210 by the arc-shaped abutting plate 300, so that the practicability of the auxiliary installation tool is improved.

[0059] It should be noted that after the lower wind deflector 100 is installed, the arc-shaped abutting plate 300 needs to be withdrawn from between the fluororubber strip 110 and the screen 210, and when being withdrawn, the one side of the arc-shaped abutting plate 300 close to the screen 210 and the one side close to the fluororubber strip 110 are respectively moved relative to the screen 210 and the fluororubber strip 110, and then cause friction, and the one side of the arc-shaped abutting plate 300 close to the screen 210 and the one side close to the fluororubber strip 110 are smoothly arranged (the roughness is 0.1-0.3 microns), which can reduce the abrasion of the screen 210 and the fluororubber strip 110 by the arc-shaped abutting plate 300, and avoid the influence on the service life of the generator.
