[0002] Indirect cooling tower is the abbreviation of indirect air cooling tower. It is a cooling device set up to cool the exhaust steam discharged to the condenser after the steam turbine has done work in the thermal power unit. In order to cool the exhaust steam of the condenser, the indirect cooling unit uses circulating water as an intermediate medium. The circulating water cools the exhaust steam of the steam turbine at the condenser. The heated circulating water is brought to the triangular radiator of the sector of the indirect cooling tower by the circulating water pump, and heat is exchanged with the cold air flowing from the bottom of the tower to the top of the tower through the triangular radiator of the sector, cooling the circulating water in the pipeline. The cooled circulating water then goes to the condenser to cool the exhaust steam of the steam turbine, and the cycle repeats.

[0003] Since dust and catkins will adhere to the triangular radiator and affect the cooling effect, the triangular radiator needs to be cleaned regularly. Whether the operator is standing in the hanging basket to wash or hoisting the washing equipment to wash, the hanging basket or the hoisted equipment will shake, and there is a risk of collision and damage to the inner wall of the triangular radiator, which is a safety hazard and affects the cleaning effect.

DETAILED DESCRIPTION

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The embodiments given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] The utility model provides a guide rail mechanism for cleaning the triangular radiator of an intercooling tower, comprising a fixing frame 1 that can be fixed on the upper end of the triangular radiator 5, at least one rope 2 is connected to the fixing frame 1, and the lower end of the rope 2 is connected to a controllable strong magnet 4, and the controllable strong magnet 4 is used to be adsorbed on the bottom plate 5-1 of the triangular radiator 5. The number of ropes 2 is set according to needs. The fixing frame 1 and the controllable strong magnet 4 cooperate to tighten the rope 2 up and down. As long as the fixing frame 1 can achieve its positioning and pulling functions and leave space for the sling to pass through in the middle of the fixing frame 1, its shape and structure are not particularly limited, and those skilled in the art can design it according to experience and professional knowledge.

[0025] like Figure 1 Shown is a preferred embodiment of the guide rail mechanism.

[0026] The fixing frame 1 of the guide rail mechanism of this embodiment includes a triangular frame body 1-1 that can be placed inside the triangular radiator 5 and a connecting portion 1-2 that connects the triangular frame body 1-1 to the upper end of the triangular radiator 5. The shape of the triangular frame body 1-1 is the same as the shape of the cross-section of the inner cavity of the triangular radiator 5. Furthermore, the distance between the outer edge of each side of the triangular frame body 1-1 and the inner wall of the corresponding triangular radiator 5 is 20 cm.

[0027] Each corner of the triangular frame 1-1 is connected with a rope 2. The rope 2 is preferably a steel wire rope, and further, a rope tightener 3 is connected to the rope 2.

[0028] The lower ends of the ropes 2 are connected to controllable strong magnets 4, and the controllable strong magnets 4 are used to be adsorbed on the bottom plate 5-1 of the triangular radiator 5. This embodiment uses controllable strong magnets 4 with a maximum lifting weight of 2 tons.

[0029] The controllable strong magnet 4 and the rope tightener 3 can be commercially available products commonly used in the art. The controllable strong magnet 4 is a product of model PML-20 produced by Shandong Qingfa Machinery Manufacturing Co., Ltd.; the rope tightener 3 is a steel wire rope tightener produced by Bazhou Senyuan Fire Equipment Factory.

[0030] like Figure 2 As shown, corresponding to the preferred embodiment of the guide rail mechanism described above, this embodiment provides an automatic cleaning device for the triangular radiator 5 of the intercooling tower.

[0031] The automatic cleaning device comprises a lifting device, a tripod 6 which can be placed in the triangular radiator 5, and a flushing device.

[0032] The lifting equipment is omitted in the figure. The lifting equipment used in this embodiment is an automatic hoist, which includes a hoist body and a PLC controller for controlling the action of the hoist body. Of course, other lifting equipment commonly used in the art, such as a crane, etc., can also be used.

[0033] The tripod 6 can be hoisted on the lifting equipment in a horizontal manner through the sling 6-1. The position of the tripod 6 matches the position of the rope 2, and a guide sleeve 8 that can be sleeved on the corresponding rope 2 is provided at its corner. In this embodiment, a guide sleeve 8 is provided at each of the three corners of the tripod 6, and each guide sleeve 8 can be sleeved on the corresponding rope 2.

[0034] The nozzle of the flushing device is fixedly connected to the center of the tripod 6 for flushing the inner wall of the triangular radiator 5. Preferably, the flushing device is a high-pressure pneumatic rotary spray device 7, which includes a high-pressure water pump, an air source and a rotary nozzle assembly, and the rotary nozzle assembly is provided with four extended water spray rods 7-1, and the four extended water spray rods 7-1 are symmetrically distributed. The upper end of the rotary nozzle assembly is fixedly connected to the tripod 6. The rotary nozzle assembly includes a rotary nozzle and a pneumatic motor. The air source is connected to the pneumatic motor. The pneumatic motor can drive the rotary nozzle to rotate. The high-pressure pump supplies water to the rotary nozzle to generate high-pressure spray water to effectively and evenly clean the inner wall of the triangular radiator 5.

[0035] In this embodiment, a position signal sensor 9 for detecting the height is connected to the tripod 6 or the flushing device, and the position signal sensor 9 is electrically connected to the PLC controller. The position sensor can be an infrared sensor. When the tripod 6 drops to a preset height, the position sensor sends a signal to the PLC controller, and the PLC controller controls the hoist body to stop moving, and can also further control the hoist to move in the opposite direction. As another optional implementation, the PLC controller presets the downward speed and downward time of the hoist hook, so that after the flushing device reaches the corresponding position, the hoist automatically stops running and then moves in the opposite direction to achieve automatic flushing. It can be understood that the above two methods are not limitations on the implementation methods, and those skilled in the art can select the above or other means of automatically controlling the motion stroke according to the actual operating conditions.

[0036] Figure 3 This utility model Figure 2 Automatic cleaning device and Figure 1 Schematic diagram of the middle guide rail mechanism in use; the specific operation method is as follows:

[0037] First, three controllable strong magnets 4 are adsorbed on the bottom plate 5-1 of the triangular radiator 5 according to the preset position, and the preset position corresponds to the position of the guide sleeve 8 of the tripod 6. The automatic cleaning device of the utility model is hoisted by a winch. The fixing frame 1 is fixedly connected to the upper end of the triangular radiator 5.

[0038] The rope 2 is passed through the hole of the corresponding guide sleeve 8 and connected to the fixing frame 1 at the upper end of the triangular radiator 5, so that the rope 2 extends in the vertical direction. Finally, the rope 2 is tightened by the rope tightener 3. In this way, the rope 2 forms a track for the automatic cleaning device to run up and down.

[0039] Driven by the winch, the high-pressure pneumatic rotary spray device 7 evenly washes the inner wall of the triangular radiator 5 from top to bottom. When the position signal sensor 9 reaches the preset position, it sends a signal to the PLC controller of the winch, and the PLC controller controls the winch body to stop moving, and can also further control the winch to move in the opposite direction.

[0040] The utility model realizes automatic flushing of the inner wall of the triangular radiator 5, and the guide rail mechanism ensures that the automatic cleaning device does not shake during the cleaning process and the cleaning effect is uniform and reliable. The guide rail mechanism has a simple structure, is easy to install, and is low in cost. Compared with a rigid track, it is more convenient and quick to disassemble and transport, and has strong practicality.

[0041] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
