Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a cooling tower cleaning device. Background Technology

[0002] Cooling towers are exposed to the elements year-round, and the strong suction of their fans allows large amounts of mud, dust, and dirt to enter the tower. Over time, this gradually reduces the cooling tower's heat dissipation capacity, easily clogs the water distributor's outlet holes, and allows mud, dust, and dirt to easily enter the cooling water system, directly affecting its normal cooling performance. To prevent these problems, cooling towers must be cleaned regularly.

[0003] Currently, cleaning is mainly carried out by rinsing, which involves spraying water and cleaning agents onto the honeycomb guide plates of the cooling tower using high-pressure nozzles to wash away loose dirt such as dust, silt, detached algae, and corrosion products. Cooling tower cleaning is generally carried out manually, which is flexible but relatively inefficient. Therefore, this application proposes a cooling tower cleaning device that can automatically clean the honeycomb guide plates of cooling towers. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing a cooling tower cleaning device, which aims to solve the problems mentioned above.

[0005] This utility model provides a cooling tower cleaning device, including a mounting frame that can be detachably installed on a cooling tower. The mounting frame is provided with a linear motion mechanism, the linear motion mechanism is provided with a lifting mechanism, and the lifting mechanism is provided with a fixed platform for installing cleaning nozzles. The lifting mechanism moves to both ends on the linear motion mechanism, so that the transmission bevel gear on the lifting mechanism meshes with the driving bevel gear at the end of the linear motion mechanism, thereby driving the fixed platform to perform lifting and lowering movements.

[0006] Preferably, the mounting frame includes an upper mounting frame and a lower mounting frame, with the linear motion mechanism mounted on the lower mounting frame. Connecting bolts are provided on the mounting frame, which is connected to the cooling tower sidewall via these bolts. The linear motion mechanism includes a drive motor, a linear screw, a helical tube, and a slider. The drive motor is fixedly mounted on one side of the lower mounting frame, the linear screw is rotatably mounted on the lower mounting frame, and driving bevel gears are located at both ends of the linear screw. The helical tube is rotatably mounted within the slider and is threadedly connected to the linear screw. An elastic locking mechanism for locking the helical tube is provided within the slider. The elastic locking mechanism includes a locking plate, a push block, a spring, and a pressure block. The locking plate and push block are slidably mounted within the slider. Multiple locking grooves for inserting into the locking plate are provided circumferentially on the outer ring of the helical tube. The push block has a V-shaped through hole, and the locking plate has a protrusion located within the V-shaped through hole. The spring is located within the slider and is connected to the end of the locking plate, allowing the locking plate to elastically insert into the locking groove. The pressure block is mounted on the lower mounting frame.

[0007] Preferably, the lifting mechanism further includes a reciprocating lead screw, a limiting rod, and a limiting block. The limiting block is rotatably mounted on a limiting slide rod of the upper mounting frame. Both ends of the reciprocating lead screw are rotatably connected to the slider and the limiting block, respectively. The limiting rod is fixedly connected to the slider and the limiting block. A fixed platform is threadedly connected to the reciprocating lead screw, and the fixed platform is slidably connected to the limiting rod. A roller or ball bearing is provided inside the limiting block, and the limiting block is rotatably connected to the limiting slide rod via the roller or ball bearing.

[0008] Preferably, there are two cleaning nozzles, which are fixed to both sides of the mounting platform by fixing sleeves. The cleaning nozzles are connected to the water pump via hoses. The fixing sleeves are connected to the mounting platform by bolts.

[0009] Compared with existing technologies, it has the following beneficial effects:

[0010] This invention uses a mounting bracket to install the cleaning equipment onto the cooling tower. A linear motion mechanism and a lifting mechanism enable the cleaning nozzles on the fixed platform to move horizontally and vertically to spray and clean the honeycomb guide plates of the cooling tower, effectively improving the cleaning efficiency. Furthermore, the detachable mounting bracket facilitates quick installation during cooling tower cleaning. Attached Figure Description

Detailed Implementation

[0020] To better understand the structure, functional features, and advantages of this utility model, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0021] Example:

[0022] like Figures 1 to 7 As shown, this utility model provides a cooling tower 10 cleaning device, including a mounting frame 1 that can be detachably installed on the cooling tower 10. A linear motion mechanism 2 is provided on the mounting frame 1, a lifting mechanism 3 is provided on the linear motion mechanism 2, and a fixed platform 5 for installing cleaning nozzles 4 is provided on the lifting mechanism 3. The lifting mechanism 3 moves to both ends on the linear motion mechanism 2, so that the transmission bevel gear 6 on the lifting mechanism 3 meshes with the driving bevel gear 7 at the end of the linear motion mechanism 2, thereby driving the fixed platform 5 to perform lifting and lowering movements.

[0023] Furthermore, the active bevel gear 7 of this invention can be one or two. When there are two, the two active bevel gears 7 are respectively fixed at both ends of the linear screw 22.

[0024] See Figure 2 The mounting bracket 1 of this utility model includes an upper mounting bracket 11 and a lower mounting bracket 12, with a linear motion mechanism 2 mounted on the lower mounting bracket 12. The mounting bracket 1 is provided with connecting bolts, and the mounting bracket 1 is connected to the side wall of the cooling tower 10 via these connecting bolts. Furthermore, the ends of the connecting bolts are provided with suction cups or rubber discs to abut against the side wall of the cooling tower 10, thereby fixing the mounting bracket 1 to the side wall of the cooling tower 10.

[0025] See Figure 2 The linear motion mechanism 2 of this utility model includes a drive motor 21, a linear screw 22, a helical tube 23, and a slider 24. The drive motor 21 is fixedly mounted on one side of the lower mounting bracket 12. The linear screw 22 is rotatably mounted on the lower mounting bracket 12, and the driving bevel gears 7 are respectively mounted on both ends of the linear screw 22. The helical tube 23 is rotatably mounted inside the slider 24 and is threadedly connected to the linear screw 22. The slider 24 is provided with an elastic locking mechanism 8 for locking the helical tube 23, so that the helical tube 23 is fixed to the slider 24 by the elastic locking mechanism 8.

[0026] See Figure 2 The elastic locking mechanism 8 of this utility model includes a locking plate 81, a push block 82, a spring 83, and a pressure block 84. The locking plate 81 and the push block 82 are slidably disposed within the slider 24. The outer ring of the screw tube 23 is provided with multiple locking grooves 231 that are inserted into the locking plate 81 along the circumferential direction. The push block 82 is provided with a V-shaped through hole 821, and the locking plate 81 is provided with a protrusion 811 located within the V-shaped through hole 821. The spring 83 is disposed within the slider 24 and is connected to the end of the locking plate 81 so that the locking plate 81 is elastically inserted into the locking groove 231. The pressure block 84 is disposed on the lower mounting bracket 12. The slider 24 moves linearly by rotating the linear screw 22. When it moves close to the mounting bracket 1, the push block 82 and the pressure block 84 first... The push block 82 moves horizontally to the left or right. When the push block 82 moves horizontally to the left or right, the V-shaped through hole 821 drives the protrusion 811 located in the middle to move vertically downward, thereby driving the locking piece 81 to move downward and compress the spring 83. This causes the end of the locking piece 81 to disengage from the locking groove 231, allowing the screw tube 23 to rotate within the slider 24. This allows the linear screw 22 to rotate synchronously with the screw tube 23. At this time, the transmission bevel gear 6 meshes with the driving bevel gear 7. When the linear screw 22 continues to rotate, it drives the reciprocating screw 31 to rotate, allowing the fixed platform 5 to move up and down under the rotation of the reciprocating screw 31. Furthermore, the drive motor 21 of this application is a forward and reverse reversing motor, which drives the linear screw 22 to rotate in both directions.

[0027] See Figure 2The lifting mechanism 3 of this utility model also includes a reciprocating screw 31, a limiting rod 32, and a limiting block 33. The limiting block 33 is rotatably mounted on the limiting slide rod 13 of the upper mounting frame 11. The two ends of the reciprocating screw 31 are rotatably connected to the slider 24 and the limiting block 33, respectively. The limiting rod 32 is fixedly connected to the slider 24 and the limiting block 33. The fixed platform 5 is threadedly connected to the reciprocating screw 31, and the fixed platform 5 is slidably connected to the limiting rod 32.

[0028] See Figure 2 The limiting block 33 of this utility model is provided with a roller or ball, and the limiting block 33 is tactilely connected to the limiting slide rod 13 through the roller or ball.

[0029] See Figure 2 The present invention has two cleaning nozzles 4, which are fixed to the two sides of the fixed platform 5 by fixing sleeves.

[0030] See Figure 2 The cleaning nozzle 4 of this utility model is connected to a water pump via a hose 9, so that water is pumped to the cleaning nozzle 4 to clean the cooling tower 10.

[0031] See Figure 2 The fixing sleeve of this utility model is connected to the fixing platform 5 by bolts to facilitate the disassembly of the cleaning nozzle 4; it can be used when the cooling tower 10 needs to be cleaned.

[0032] In another embodiment of this utility model, the linear screw 22 is replaced by a reciprocating lead screw 31. The output end of the drive motor 21 is connected to the reciprocating lead screw 31 via a coupling to drive the slider 24, which is slidably connected thereto, to reciprocate on the reciprocating lead screw 31. In this embodiment, the reciprocating lead screw 31, which is rotatably disposed on the slider 24 and the limiting block 33, is driven by a motor disposed on the slider 24. The motor is driven by a bevel gear meshing with a transmission bevel gear 6.
