Referring to fig. 1-3, a cooling tower cleaning system 100 provided herein includes a support frame 10, a screen assembly 20, a spray device 30, and a moving device 40. Wherein the bracket 10 is configured to be disposed on an outer periphery of the cooling tower 200, that is, an outer wall of the cooling tower body 201.

Through setting up spray set 30 in the side towards cooling tower 200 of filter screen subassembly 20, like this, spray the subassembly and can wash away filter screen subassembly 20 from inside to outside, avoid the pollutant to utilize the shower rivers to enter into the inside of cooling tower 200, ensure clean effect. The moving device 40 can drive the spraying device 30 to move, so that the spraying range is increased, the whole filter screen assembly 20 can be washed by the spraying water, cleaning is not needed in the process by using manpower, and the cleaning efficiency is improved.

Illustratively, the support 10 includes a top plate 11 and side plates 12 connected to both ends of the top plate 11, the top plate 11 and the side plates 12 enclose to form a receiving chamber 13, the spraying device 30 and the moving device 40 are disposed in the receiving chamber 13, one side of the support 10 is connected to the cooling tower 200, and the other side is provided with the filter screen assembly 20. That is, the top plate 11 and the side plate 12 of the bracket 10 have a certain width, so that the bracket 10 formed by surrounding the top plate 11 and the side plate 12 is n-shaped, and further installation of the filter screen assembly 20, the spraying device 30 and the moving device 40 can be facilitated. Along the thickness of the bracket 10, as shown in fig. 1 in the x-direction, the bracket 10 has two sides, one for connection with the cooling tower body 201, and the other side may be provided with a screen assembly 20. In this way, when the spray device 30 is disposed in the receiving chamber 13, the spray device 30 can be located between the screen assembly 20 and the outer wall of the cooling tower body 201. When spray set 30 sprays water toward filter screen assembly 20, water flow can be sprayed from the interior of support 10 to the exterior of support 10 to when washing the pollutant on filter screen assembly 20, avoid pollutant to flow into the interior of support 10 along the water flow, cause the pollution of the interior parts in cooling tower body 201. The accommodating cavity 13 formed by the bracket 10 can also provide shielding effect for the spraying device 30 and the moving device 40, prevent the spraying device 30 and the moving device 40 from being exposed, reduce pollution or damage of external pollutants to the spraying device 30 or the moving device 40, and improve the reliability and service life of the cooling tower cleaning system 100. Of course, screen assembly 20 can also be retracted a distance in the x-direction to provide a degree of shielding for screen assembly 20 by bracket 10.

Or in other examples, the bracket 10 may be fixed in the cooling tower body 201 using bolts or rivets by providing corresponding through holes in the bracket 10 and the cooling tower body 201. Alternatively, the height of the side plate 12 may be identical to the height of the cooling tower body 201, and the length of the top plate 11 is identical to the width of the cooling tower body 201, so that after the bracket 10 is mounted to the cooling tower body 201, the edge of the bracket 10 is substantially flush with the edge of the cooling tower body 201, so that the overall outer contour shape of the cooling tower 200 is smoother, and the shape of the cooling tower 200 is not greatly changed compared to that before the cooling tower cleaning system 100 is mounted, thereby facilitating daily maintenance of the cooling tower 200.

In some embodiments, the moving device 40 includes a driving part 41 and a transmission part 42, one end of the transmission part 42 is connected to the spraying device 30, the other end is connected to the driving part 41, and the driving part 41 is used for driving the transmission part 42 to drive the spraying device 30 to move. The driving part 41 can automatically drive the transmission part 42 to move after being electrified and started, so that the spraying device 30 is driven to move, and the cleaning efficiency is improved by improving the range of spraying coverage. Meanwhile, the driving part 41 driven by electricity can reduce the manual cleaning operation, and improve the cleaning convenience of the cooling tower 200.

Illustratively, the driving device may employ a motor, a cylinder, or the like. The transmission member 42 may be a belt, a toothed chain, a link, or a transmission rope 421. Accordingly, a power line and a switch may also be provided to control the turning on or off of the driving means. The power line may be provided along the inner wall or the outer circumference of the bracket 10, and the switch may be provided at the side of the cooling tower body 201 or outside the side plate 12 of the bracket 10.

In some embodiments, the driving component 42 includes a driving rod 420 and a driving rope 421, the driving component 41 and the driving rod 420 are both disposed at the top of the support 10, the spraying device 30 is located below the driving rod 420, one end of the driving rope 421 is connected to the driving rod 420, the other end is connected to the spraying device 30, and the driving component 41 drives the driving rod 420 to rotate so as to drive the driving rope 421 to wind around the driving rod 420 or unwind from the driving rod 420, so as to drive the spraying device 30 to move.

Because the spraying device 30 is arranged below the transmission rod 420, the spraying device 30 and the driving component 41 are connected through the transmission rope 421, so that the gravity of the spraying device 30 can be utilized to stretch the transmission rope 421 to a tension state, and the spraying device 30 can be in a natural sagging state. When the driving part 41 drives the driving rod 420 to rotate in a certain direction along the axial direction of the driving rod 420, the driving rope 421 can be wound on the driving rod 420, so that the distance between the spraying device 30 and the driving part 41 is shortened, that is, the spraying device 30 is lifted upwards in the vertical direction; when the driving part 41 rotates the driving lever 420 in the opposite direction, the driving rope 421 wound around the driving lever 420 is released, and the spraying device 30 is lowered at this time so that the spraying device 30 can be moved downward. By controlling the spray device 30 to move up and down along the vertical direction in the above manner, the spray coverage range can be increased, and thus the spray cleaning effect is improved. By adopting the proposal of the transmission rod 420 and the transmission rope 421, the volume of the transmission part 42 can be reduced, thereby saving the space of the accommodating cavity 13 in the bracket 10.

It will be appreciated that in the above example, the driving part 41 and the transmission rod 420 are both provided at the top of the stand 10, that is, the top plate 11 of the stand 10, so that the shower device 30 can be moved in the up-down direction when the shower device 30 is driven. Of course, in other examples, the driving component 41 may also be disposed on the side plate 12 of the bracket 10, and the driving component 41 is connected with the spray rod 31 by using the transmission rod 420, so as to drive the spraying device 30 to move in a horizontal direction (for example, in a y direction in fig. 1), so that the filter screen assembly 20 can be fully sprayed.

Illustratively, the driving rope 421 may be a wire structure, such as a wire of a steel wire or a non-metal material and having a high strength, or a bar-shaped structure woven from the wires, or a chain structure. The transmission rod 420 can be made of steel pipe or plastic pipe.

By using the rod-like structure of the spray bar 31, the water outlet area during spraying can be increased, thereby improving the efficiency of spraying and flushing. Since the spray bar 31 and the transmission bar 420 are each of a rod-like structure, they may preferably be provided to be substantially the same length. In this way, the driving rope 421 can be respectively connected to two ends of the spray rod 31 and the driving rod 420, and the spray rod 31 is in a substantially parallel state with the driving rod 420, so as to improve stability of the spray rod 31 in the moving process, avoid the deflection or side skew of the spray rod 31, and improve operational reliability of the cooling tower cleaning system 100.

Alternatively, the spray device 30 is provided with a plurality of nozzles 32, and the plurality of nozzles 32 are disposed at equal intervals along the length direction of the spray bar 31. In this way, the number of water outlets of the spraying device 30 and the coverage range of the water outlet can be increased, so that the filter screen assembly 20 is more uniformly washed, and the cleaning effect is improved. In some preferred embodiments, the spray head is a stainless steel atomizer spray head, which further increases the area of the water exiting, and provides uniform water exiting, thereby improving the scouring effect on the screen assembly 20. It will be appreciated that the spray device 30 may be configured as a shower, for example, in addition to the embodiments described above.

During operation of the cooling tower 200, since a portion of the circulating water is evaporated in the form of water vapor during the heat exchange, the cooling tower body 201 is generally provided with a water supplementing passage, and water is introduced from the outside of the cooling tower 200 to ensure that the circulating water in the refrigeration cycle is maintained in a reasonable range.

Specifically, the water intake pipe 33 is connected to the water supplementing channel, the cooling water is introduced into the spraying device 30 by using the water intake pipe 33, the spraying device 30 further comprises a hose 36 and a water supplementing valve 34, the water supplementing valve 34 is arranged on the water intake pipe 33, the water supplementing valve 34 is used for controlling the communication or interruption between the water supplementing channel of the cooling tower 200 and the water intake pipe 33, one end of the hose 36 is connected to the spray boom 31, and the other end is connected to the water supplementing valve 34. In the form of a hose 36, it is convenient to follow the position of the spray bar 31 during the movement of the spray bar 31, so as to accommodate the height variation of the spray bar 31. It will be appreciated that in order to ensure that the water supplied by the boom 31 has sufficient water pressure, a high pressure water pump 35 may be provided in the intake pipe 33, with the water pump 35 in the intake pipe 33 being pumped into the boom 31 by the water pump 35.
