[0041] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0042] like Figures 1-3 As shown in the figure, a boiler water supply and cooling device 100 for power plants according to an embodiment of the present invention includes an annular cylinder 1, a base assembly 2, a water supply assembly 3, a rotating water spray assembly 4, and a drive assembly 5.

[0043] The top end of the annular cylinder 1 is fixedly connected to a water inlet pipe 11, and the bottom end of the annular cylinder 1 is fixedly connected to a water outlet pipe 12.

[0044] The base assembly 2 includes a base body 21 and a fixing ring 22; the annular cylinder 1 is fixed to the top of the base body 21, and the fixing ring 22 is sleeved on the outer periphery of the bottom of the annular cylinder 1 and fixedly connected to the base body 21; the top of the fixing ring 22 is provided with an annular rotating groove 220.

[0045] The rotating water spray assembly 4 includes a rotating bracket 41 and a water spray pipe 42; the rotating bracket 41 has a water spray channel that penetrates the upper and lower surfaces of the rotating bracket 41; the top of the rotating bracket 41 has an annular water receiving groove 410; the water spray pipe 42 is fixed in the water spray channel and extends vertically; the water spray pipe 42 is connected to the water receiving groove 410; multiple sets of water spray holes 420 are spaced apart on the outer periphery of the water spray pipe 42, and each set of water spray holes 420 is spaced apart in the vertical direction, and the water spray holes 420 penetrate the inner and outer surfaces of the water spray pipe 42; the rotating bracket 41 is sleeved on the outer periphery of the annular cylinder 1 and rotatably connected to the rotating groove 220; a rack 43 is provided around the bottom outer periphery of the rotating bracket 41.

[0046] The drive assembly 5 includes a motor 51 and a drive gear 52. The motor 51 is fixedly mounted on the base body 21, and the drive gear 52 is horizontally arranged and fixedly connected to the main shaft of the motor 51. The drive gear 52 is meshed with the rack 43.

[0047] The water supply component 3 is connected to the base body 21, and the water supply component 3 is used to supply water to the water receiving tank 410.

[0048] Based on the above technical solution, the rotation of the main shaft of the motor 51 drives the drive gear 52 to rotate, which in turn drives the rack 43 meshing with it to rotate, thereby driving the rotating bracket 41 rotatably connected to the rotating groove 220 to rotate. Water is supplied to the water receiving tank 410 through the water supply component 3. The water in the water receiving tank 410 flows to the water spray pipe 42 connected to the water receiving tank 410 and is sprayed out from the water spray hole 420 in the water spray pipe 42, thereby spraying water onto the outer surface of the annular cylinder 1. Under the rotation of the rotating bracket 41, the water is sprayed around the annular cylinder 1, thereby spraying the outer circumference of the annular cylinder 1 to achieve cooling, making the spray coverage complete, which is beneficial to improving cooling efficiency and cooling effect. Moreover, compared with the prior art, the number of water spray pipes is reduced, which can effectively reduce water resource consumption.

[0049] Furthermore, such as Figure 1 As shown, in order to collect the water sprayed onto the surface of the annular cylinder 1 for reuse and thus reduce water waste, the power plant boiler water supply cooling device 100 also includes a water collection assembly 6, which includes a water collection tank 61 and a water collection pipe 62.

[0050] The base body 21 has an installation cavity 210, and the upper surface of the base body 21 also has a drainage hole 2101. The drainage hole 2101 is located between the fixing ring 22 and the annular cylinder 1, and the drainage hole 2101 communicates with the installation cavity 210.

[0051] Both the water collection tank 61 and the water collection pipe 62 are installed in the mounting cavity 210. The two ends of the water collection pipe 62 are connected to the drain hole 2101 and the water collection tank 61, respectively. When water is sprayed onto the surface of the annular cylinder 1, most of the water flows to the upper surface of the base body 21 and then flows from the drain hole 2101 to the water collection pipe 62, thereby collecting the water into the water collection tank 61 by the water collection pipe 62.

[0052] Furthermore, such as Figure 1 As shown, the water supply component 3 supplies water to the water receiving tank 410; the water supply component 3 includes a water supply tank 31, a water supply pipe 32, and a water pump 33.

[0053] The water supply tank 31 and the water pump 33 are both installed in the mounting cavity 210. The water supply tank 31 is provided with a first water outlet, which is connected to the input end of the water pump 33.

[0054] The water supply pipe 32 passes through the mounting cavity 210. One end of the water supply pipe 32 is connected to the output end of the water pump 33, and the other end of the water supply pipe 32 is located in the water receiving tank 410. By installing the water supply tank 31 in the mounting cavity 210, the space of the mounting cavity 210 can be effectively utilized, and it is convenient for the power plant to process the water supply tank 31 and the water collection tank 61 simultaneously in the same space. The water pump 33 pumps the water in the water supply tank 31 to the water receiving tank 410 through the water supply pipe 32, thereby realizing the water supply to the spray pipe 42 and ensuring the normal operation of the spraying work.

[0055] Furthermore, such as Figure 1 and Figure 2 As shown, the water supply assembly 3 also includes a fixing plate 34, which is vertically fixed to the top of the base body 21. The water supply pipe 32 includes a first section 321, a second section 322, and a third section 323 connected sequentially from top to bottom. The second section 322 is vertically positioned above the base body 21. The first section 321 is bent so that one end of the water supply pipe 32 is located in the water receiving trough 410. The third section 323 is located in the mounting cavity 210 and is used to connect to the output end of the water pump 33. The second section 322 is fixedly connected to the fixing plate 34. By fixing the second section 322 of the water supply pipe 32 to the fixing plate 34, the stability of the water supply pipe 32 is improved, preventing the water supply pipe 32 from tipping over and causing one end of the water supply pipe 32 to be located in the water receiving trough 410, thus preventing water supply to the water receiving trough 410.

[0056] Preferably, such as Figure 1 and Figure 2 As shown, the water supply assembly also includes clamps 35. The second segment 322 is fixedly connected to the fixing plate 34 by a plurality of clamps spaced apart along the vertical direction, so as to achieve a fixed connection between the second segment 322 and the fixing plate 34 without damaging the body of the water supply pipe 32.

[0057] Furthermore, such as Figure 3 As shown, to specifically realize the rotating bracket 41 being rotatably connected to the rotating groove 220, the bottom of the rotating bracket 41 is fixed with an annular retaining ring 44, which is inserted into the rotating groove 220; the rotating bracket 41 is rotatably connected to the rotating groove 220 through the retaining ring 44.

[0058] Furthermore, such as Figure 3 As shown, the rotating water spray assembly 4 also includes a ball bearing 45;

[0059] The lower surface of the retaining ring 44 is provided with a plurality of connecting grooves 440, and the plurality of connecting grooves 440 are evenly spaced along the circumferential direction of the retaining ring 44.

[0060] Each of the connecting grooves 440 is rotatably connected to a ball bearing 45. By rotatably connecting the ball bearing 45 to the connecting groove 440, the smoothness of the retaining ring 44 during rotation is improved.

[0061] Furthermore, such as Figure 1 As shown, in order to further improve the cooling efficiency of the annular cylinder 1, the rotating water spray assembly 4 also includes a fan plate 46, which is vertically arranged and fixed in the water spray channel; the fan plate 46 is spaced apart from the water spray pipe 42, and the fan plate 46 is arranged perpendicular to the annular cylinder 1.

[0062] Furthermore, such as Figure 1 As shown, the rotating support 41 includes a first rotating ring 411, a second rotating ring 412, and uprights 413. The first rotating ring 411 and the second rotating ring 412 are spaced apart from top to bottom, and multiple uprights 413 are spaced apart between the first rotating ring 411 and the second rotating ring 412. The two ends of each upright are fixedly connected to the first rotating ring 411 and the second rotating ring 412, respectively. The top of the first rotating ring 411 has a water receiving groove 410, and the second rotating ring 412 is rotatably connected to the rotating groove 220. The outer periphery of the second rotating ring 412 is provided with a rack 43. The rotating support 41 is formed by assembling the first rotating ring 411, the second rotating ring 412, and the uprights 413. There are gaps between adjacent uprights 413 to allow air to circulate between the inner and outer sides of the rotating support 41, so that water can evaporate quickly to remove heat from the annular cylinder 1, thereby improving the cooling effect on the annular cylinder 1.

[0063] Furthermore, such as Figure 1 As shown, to achieve the fixed connection of the fan plate 46, the rotating bracket 41 also includes a vertical rod 414; the vertical rod 414 is disposed between the first rotating ring 411 and the second rotating ring 412, and the two ends of the vertical rod 414 are respectively fixedly connected to the first rotating ring 411 and the second rotating ring 412; the fan plate 46 is fixedly connected to the vertical rod 414.

[0064] Furthermore, such as Figure 1 As shown, the water collection assembly 6 also includes a drain pipe 63 and a solenoid valve 64; the water collection tank 61 also has a second water outlet, the drain pipe 63 is connected to the second water outlet, and the solenoid valve 64 is installed in the drain pipe 63. By setting the second water outlet and the drain pipe 63, the water in the water collection tank 61 can be discharged for secondary use, and the solenoid valve 64 helps to control the discharge of water from the water collection tank 61.

[0065] The working process of this utility model is as follows:

[0066] Water from the water supply tank 31 is pumped by the water pump 33 to the water receiving tank 410 via the water supply pipe 32. The water in the water receiving tank 410 flows into the spray pipe 42 and is sprayed onto the outer circumference of the annular cylinder 1 through the spray holes 420. The motor 51 is started, and the main shaft of the motor 51 rotates, driving the drive gear 52 to rotate, thereby driving the rotating bracket 41 to rotate as a whole. The rotation of the rotating bracket 41 enables the spray pipe 42 to spray around the annular cylinder 1 and drive the fan plate 46 to rotate, fanning the outer circumference of the annular cylinder 1 to accelerate water evaporation and remove heat, thereby improving heat dissipation efficiency.

[0067] Water sprayed onto the outer circumference of the annular cylinder 1 is collected into the water collection tank 61 through the drain hole 2101 and the water collection pipe 62, and discharged through the drain pipe 63 and the solenoid valve 64.

[0068] In summary, this utility model provides a boiler water supply and cooling device 100 for power plants, which includes an annular cylinder 1, a base assembly 2, a water supply assembly 3, a rotating water spray assembly 4, and a drive assembly 5. The rotation of the main shaft of the motor 51 drives the drive gear 52 to rotate, thereby driving the rack 43 meshing with it to rotate, which in turn drives the rotating bracket 41 rotatably connected to the rotating groove 220 to rotate. Water is supplied to the water receiving tank 410 through the water supply assembly 3. Water flows from the 0 to the spray pipe 42 connected to the water receiving tank 410, and is sprayed out from the spray holes 420 in the spray pipe 42, thereby spraying water onto the outer surface of the annular cylinder 1; and under the rotation of the rotating bracket 41, it sprays around the annular cylinder 1, thereby spraying the outer circumference of the annular cylinder 1 to achieve cooling, making the spray coverage complete, which is beneficial to improving cooling efficiency and cooling effect; and compared with the prior art, the number of spray pipes is reduced, which can effectively reduce water resource consumption.
