Detailed implementation manners

[0024] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] Embodiment 1: A flip - type air cooler device for a generator set as shown in Figures 1 to 4 includes an air cooler body 1. The air cooler body 1 includes an upper end cover 11, a lower end cover 12, and copper tubes 13 arranged between the two. Cooling water flows through the copper tubes 13. An air cooler inlet valve 21 is installed at the water inlet of the copper tubes 13. The air cooler inlet valve 21 is detachably and fixedly connected to the cooling water inlet valve 22. An air cooler outlet valve 31 is installed at the water outlet of the copper tubes 13. The air cooler outlet valve 31 is detachably and fixedly connected to the cooling water outlet valve 32. The cooling water inlet valve 22 and the cooling water outlet valve 32 are both located below the air cooler body 1 and are connected to the external cooling water pipeline to jointly form a cooling water circulation body. The upper and lower ends of the air cooler body 1 are movably connected to the air outlet 4 of the stator frame, that is, the air cooler body 1 can rotate around its upper and lower ends to achieve separation or closure with the air outlet 4 of the stator frame. The air cooler body 1 is fixedly connected to the air outlet 4 of the stator frame circumferentially by bolts. During normal operation, the air cooler body 1 remains in a closed state. When maintenance is required, the bolts are removed and the air cooler body 1 is flipped to be separated from the air cooler body 1 and in an open state. The air cooler body 1 can also adjust its own height through a height adjustment mechanism.

[0026] In this embodiment, by rotatably connecting the upper and lower ends of the air cooler body 1 to the air outlet of the stator frame 4, the separation or closure of the air cooler body 1 and the air outlet of the stator frame 4 is realized, so that it is in a closed state during the normal use of the air cooler of the generator set, and only the air cooler body 1 needs to be rotated to open when maintenance is required. The air cooler body 1 is in a fully open state, which is convenient for checking and replacing the relevant sensor monitoring components on the back of the air cooler body 1, and the operation is very convenient, solving the problem of the complex disassembly work and time-consuming and laborious in the background technology during maintenance; in addition, by setting a height adjustment mechanism, it is convenient to lift the height of the air cooler body 1 when maintenance is required, so that it is separated from the cooling water inlet valve 22 and the cooling water outlet valve 32, and the air cooler body 1 can be conveniently opened; and by setting the air cooler inlet valve 21 of the air cooler body 1 to be fixedly connected to the cooling water inlet valve 22, and the air cooler outlet valve 31 to be fixedly connected to the cooling water outlet valve 32, it can further improve the connection stability between the air cooler body 1 and the stator frame during the operation of the air cooler of the generator set, and only the corresponding inlet valve and outlet valve need to be removed when maintenance is required, without draining the water in the air cooler body 1, which is more convenient to use.

[0027] Embodiment 2: On the basis of Embodiment 1, an optimal design is carried out on the connection mode between the air cooler body 1 and the air outlet of the stator frame 4. The same side of the upper and lower ends of the air cooler body 1 (i.e., the same edge of the upper and lower end faces) is respectively movably connected to the upper fixed hinge 5 and the lower fixed hinge 6, wherein the upper fixed hinge 5 and the lower fixed hinge 6 are fixed on the stator base of the air outlet of the stator frame 4, that is, the upper fixed hinge 5 is fixed on the upper part of the stator base, and the lower fixed hinge 6 is fixed on the lower part of the stator base.

[0028] Further, the upper fixed hinge 5 includes an upper bearing seat 51 and an upper bearing 52. The bottom end of the upper bearing 52 is vertically and fixedly connected to one side of the upper end cover 11 of the air cooler body 1, and the top end passes through the upper bearing seat 51 and can rotate in the upper bearing seat 51. The fixed surface of the upper bearing seat 51 is fixedly connected to the top of the stator base by means of threaded connection. The upper bearing 52 is a smooth cylindrical structure and can move up and down in the upper bearing seat 51, which is convenient for adjusting the height of the air cooler body 1.

[0029] Further, the lower fixed hinge 6 includes a lower bearing seat 61 and a lower bearing 62. The top end of the lower bearing 62 is vertically and fixedly connected to one side of the lower end cover 12 of the air cooler body 1, and the bottom end passes through the lower bearing seat 61. The lower bearing seat 61 is fixedly connected to the lower part of the stator base by means of threaded connection. Among them, the upper fixed hinge 5 and the lower fixed hinge 6 are on the same side of the air cooler body 1.

[0030] Thus, in this embodiment, the cooperation of the upper fixed hinge 5 and the lower fixed hinge 6 enables the air cooler body 1 to freely flip around its connected side, eliminating the need for lifting methods such as bridge cranes and hoists to quickly remove the air cooler body 1 for maintenance work. Here, the upper bearing seat 51 and the lower bearing seat 61 provide a rotation fulcrum for the flipping of the air cooler body 1, and the upper bearing 52 and the lower bearing 62 are integrated with the air cooler body 1 to achieve overall flipping.

[0031] Furthermore, the lower bearing 62 has a full thread on its shaft body and is threadedly connected to the lower bearing seat 61. The height adjustment mechanism includes an adjustment nut 63, which is sleeved on the shaft body of the lower bearing 62 between the lower bearing seat 61 and the lower end cover 12. That is, by rotating the adjustment nut 63, the lower bearing 62 can rise or fall within the lower bearing seat 61, thereby adjusting the height of the air cooler body 1. Thus, the adjustment nut 63 and the connection method that the upper bearing 52 can move up and down within the upper bearing seat 51 cooperate to jointly adjust the height of the air cooler body 1, realizing lifting the air cooler body 1 to a certain height during maintenance, separating the inlet and outlet valves of the air cooler body 1 from the inlet and outlet valves of the cooling water, and facilitating the overall flipping of the air cooler body 1.

[0032] Furthermore, a thrust bearing 64 is also sleeved on the shaft body of the lower bearing 62. The thrust bearing 64 is located between the adjustment nut 63 and the lower bearing seat 61 and is in contact with both. The thrust bearing 64 helps reduce friction and withstand pressure, enables smooth rotation between the connecting parts, and thus extends its durability. In this embodiment, it is used to bear the weight of the entire air cooler body 1, reduce the friction during the flipping of the air cooler body 1, and make its rotation more flexible.

[0033] Embodiment 3: On the basis of Embodiment 1, a sealing strip 41 is further installed circumferentially at the air outlet 4 of the stator frame. The sealing strip 41 is connected to the back of the air cooler body 1 to maintain the connection tightness between the air cooler body 1 and the air outlet 4 of the stator frame during the operation of the generator set air cooler.

[0034] Embodiment 4: On the basis of Embodiment 1, the air cooler inlet valve 21 is fixedly connected to the cooling water inlet valve 22 by bolts, and the air cooler outlet valve 31 is fixedly connected to the cooling water outlet valve 32 by bolts. The air cooler inlet valve 21 and the air cooler outlet valve 31 are connected by bolts. During maintenance, the air cooler inlet valve 21 and the air cooler outlet valve 31 can be quickly detached from the cooling water inlet valve 22 and the cooling water outlet valve 32, which is more convenient for maintenance.

[0035] When the generator set air cooler is normally put into operation, such as Figure 2As shown, the air cooler body 1 and the stator frame air outlet 4 are in a closed state. The air cooler water inlet valve 21 is connected to the cooling water inlet valve 22 by bolts, the air cooler water outlet valve 31 is connected to the cooling water outlet valve 32 by bolts, and the air cooler body 1 is fixed to the stator base by bolts. When it is necessary to seal the air cooler of the generator set or check and replace the relevant sensor monitoring components on the back of the air cooler of the generator set, first close the cooling water inlet valve 22, the cooling water outlet valve 32, the air cooler water inlet valve 21 and the air cooler water outlet valve 31, then remove the bolts connecting the air cooler water inlet valve 21 and the cooling water inlet valve 22, the bolts connecting the air cooler water outlet valve 31 and the cooling water outlet valve 32, and the bolts connecting the air cooler body 1 and the stator frame air outlet 4. Finally, lift the air cooler body 1 by a certain height by adjusting the nut 63 so that the inlet and outlet valves of the air cooler body 1 are separated from the inlet and outlet valves of the cooling water, and gently rotate the air cooler body 1 to complete the flipping of the air cooler body 1. When the air cooler body 1 is in the fully open state, as Figure 1 shown, relevant maintenance work can be carried out in this state.

[0036] The above embodiments only represent the specific implementation manners of the present application, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the technical solution of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
