[0023] In order to make the purpose, technical scheme and advantages of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] In modern industrial production, efficient operation of the generator is crucial, and the hydrogen cooler as a key component of the generator cooling system directly affects the performance and life of the generator. The generator hydrogen cooler cleaning equipment provided by the utility model effectively solves many problems in the hydrogen cooler cleaning process through a series of innovative designs, greatly improving the safety, effect and working efficiency of cleaning.

[0025] The generator hydrogen cooler cleaning equipment provided by the utility model, the core revolves around the hydrogen cooler 8, and the main components include the flushing cart 1, the waterproof front end cover 2 and the waterproof rear end cover. The flushing cart 1 is connected with the waterproof front end cover 2 through the water inlet pipe, and the hydrogen cooler 8 is stably fixed between the waterproof front end cover 2 and the waterproof rear end cover. This structure design forms a relatively closed cleaning space, which provides a basic guarantee for the subsequent cleaning work.

[0026] As shown in Figure 1 The two end faces of the hydrogen cooler 8 are fixed on one side of the flange cover shell 3 respectively, and a sealing square bar 5 is installed between them. In order to ensure the stability of the connection, the end face of the hydrogen cooler 8 and the flange cover shell 3 are fastened by a plurality of bolts, and 12 bolts are uniformly distributed around. In actual operation, the 12 bolts are distributed according to accurate spacing and position, and uniformly exert the fastening force, so that the hydrogen cooler 8 and the flange cover shell 3 are tightly fitted. At the same time, the sealing square bar 5 plays an important role, which is filled in the contact gap between the hydrogen cooler 8 and the flange cover shell 3 to prevent water from penetrating in the cleaning process. In addition, the flange cover shell 3 is processed by 2mm aluminum alloy sheet, and the surface is treated by anodic oxidation. The anodic oxidation treatment not only improves the corrosion resistance of the flange cover shell 3, so that it can be used in a humid cleaning environment for a long time without being corroded, but also enhances the wear resistance and prolongs the service life of the equipment. The characteristics of aluminum alloy material itself ensure the structural strength, at the same time, reduce the weight of the equipment, so that it is more convenient in the process of installation, disassembly and transportation, and convenient for operators to maintain and operate.

[0027] The flange cover 3 is provided with an intermediate downwardly inclined water receiving groove 5 at the bottom end of the side away from the hydrogen cooler 8, and the water receiving groove 5 is provided with a sewage outlet 6. The flange cover 3 is a square shell with open ends, and the water receiving groove 5 is arranged on the inner wall of the bottom end thereof. When the hydrogen cooler 8 is cleaned, the water flow will carry dirt out of the hydrogen cooler 8, and the inclined design of the water receiving groove 5 can guide the water flow to naturally converge at the sewage outlet 6. The sewage outlet 6 is like a “drainage hub” that concentrates the sewage generated during cleaning and is discharged, avoiding the accumulation of sewage inside the equipment, keeping the inside of the equipment clean, and preventing corrosion or damage to other parts of the equipment due to the accumulation of sewage.

[0028] As shown in Figure 1 , the waterproof front end cover 2 and the waterproof rear end cover are square pyramidal shells with open bottoms, and the open ends are fixed on the side of the flange cover 3 provided with the sewage outlet 6. They are made of transparent waterproof plastic soft curtain structure, and the length of the soft curtain is customized according to the maximum hole distance size of the inner diagonal of the orifice plate to ensure that it can extend to each position of the cooler orifice plate. During cleaning, the water flow flows down along the inner wall of the soft curtain, guiding the water flow to converge at the sewage outlet 6 at the bottom, optimizing the guidance and distribution of the water flow, and improving the cleaning efficiency. The transparent waterproof plastic soft curtain structure not only ensures good waterproof performance, but also allows operators to observe the internal situation during cleaning, real-time monitor the cleaning progress and effect, and ensure the comprehensiveness and thoroughness of the cleaning work.

[0029] As shown in Figure 2 and Figure 5 , the waterproof front end cover 2 and the waterproof rear end cover are connected to the flange cover 3 by a buckle 6. The buckle includes a horizontal clamp 6.1 fixed to the flange cover, one end of the horizontal clamp 6.1 is provided with a strip-shaped pressing plate 6.2, and the strip-shaped pressing plate 6.2 is in contact with and fixed to the waterproof front end cover and the waterproof rear end cover. The bottom end of the horizontal clamp 6.1 is provided with a fixed seat, and the fixed seat is connected through a plurality of rotating shafts and movable handles. The length of the rotating shaft close to the strip-shaped pressing plate 6.2 is less than the length of the rotating shaft at the other end, and the buckle 6 is connected in a simple and convenient manner. During installation, the operator only needs to align the buckle 6 with the corresponding position and gently operate the movable handle to complete the connection; when it is necessary to replace the aging waterproof front end cover 2 and the waterproof rear end cover later, the buckle 6 can also be easily opened, and the old soft curtain can be removed and replaced with a new one. This connection method greatly simplifies the installation and replacement process, reduces maintenance costs, improves the operability and flexibility of the equipment.

[0030] As shown in Figure 1As shown, the elastic necking 4 is provided on the tip of the waterproof front end cover 2, and is parallel to the end face of the hydrogen cooler 8, and the water gun 7 is arranged perpendicularly to the end face of the hydrogen cooler 8 and connected to the water inlet pipe. The design of the elastic necking 4 is a clever detail, which can adapt to the shape and position of the end face of the hydrogen cooler 8, ensuring that the water gun 7 can flush to each position of the end face of the hydrogen cooler 8. When the water gun 7 sprays water, this close fit waterproof can make the water flow evenly distributed on the end face of the hydrogen cooler 8, avoiding the situation that the water flow cannot be sprayed, thereby improving the cleaning effect. At the same time, the water gun 7 is arranged perpendicularly to the end face of the hydrogen cooler 8, further optimizing the water flow impact angle, so that the water flow can act on the dirt on the surface of the hydrogen cooler 8 with the greatest impact force, enhancing the cleaning ability of the dirt, ensuring that the cleaning process is more efficient and thorough.

[0031] The waterproof rear end cover is connected to the water outlet pipe, and a filter screen is arranged on the side close to the end face of the hydrogen cooler 8. The filter screen is made of stainless steel material and can be easily disassembled and washed. During the cleaning process, the dirty water after cleaning will carry various dirt from the hydrogen cooler 8 and pass through the waterproof rear end cover. The filter screen acts like a "guardian" and can effectively prevent large particles from flowing out with the water flow and entering the subsequent pipeline system. If large particles enter the pipeline, it may cause pipeline blockage and affect the normal operation of the equipment. The filter screen made of stainless steel material has good corrosion resistance and can be used in a humid environment for a long time without rusting, and its durability also ensures the service life of the filter screen. In addition, the filter screen is easy to disassemble and wash, and the operator can regularly disassemble and clean the filter screen to ensure that its filtering effect remains good at all times, reducing maintenance costs.

The stainless steel cold and hot water circulating pump can ensure the stability and high pressure output of the water flow, and the powerful water pressure can effectively remove stubborn dirt in the hydrogen cooler 8. The frequency conversion debugging function can flexibly adjust the water flow pressure according to the cleaning demand, can accurately control the water pressure when cleaning the hydrogen cooler 8 with different degrees of dirt, and improves the adaptability and cleaning effect of the equipment. The circulating pump automatically runs, and when the cleaning work is turned off, the circulating pump stops running synchronously. The automatic design simplifies the operation process, improves the work efficiency, and reduces the manual intervention.

[0034] As shown in Figure 2 The lower surface of the flushing trolley 1 is provided with a plurality of rollers 1.4 and handles 1.3, four rollers 1.4 are preferably arranged in the embodiment, the rollers 1.4 are provided with brake parts, two radial and two universal belt brakes. The design of the rollers 1.4 and the handles 1.3 makes the flushing trolley 1 have good mobility, and the operator can easily push the trolley to move and position between different sites. When it is necessary to fix the position of the trolley for cleaning operation, the brake parts can play a role to ensure the stability of the equipment during operation and avoid safety hazards caused by accidental movement. The flushing trolley 1 is also provided with two sets of high-pressure water guns 7, and the preparation inlet and outlet pipes are about 10 meters, and the drain pipe is about 15 meters. The long distance of the inlet and outlet pipes and the drain pipe and the equipped multiple sets of high-pressure water guns 7 further improve the flexibility and application range of the equipment, which can meet the cleaning needs in different scenes, whether in a narrow space machine room or in a large maintenance workshop, the hydrogen cooler 8 cleaning work can be conveniently carried out.

[0035] The flushing trolley 1 is provided with a pressure valve for adjusting the pressure of the water gun 7, and the working modes are divided into standard mode, strong mode and general mode. The operator can adjust the water quantity at the pump outlet by adjusting the opening degree of the manual valve behind the flushing trolley 1, so as to realize mode switching. A pointer type pressure gauge is installed at the pipeline, and the operator can directly observe the pressure change, and flexibly adjust the pressure of the water gun 7 according to different cleaning requirements and dirt levels. When cleaning the hydrogen cooler 8 with light dirt, the standard mode or the general mode can be selected, so that the cleaning effect can be ensured and the equipment can be prevented from being damaged due to too high pressure; when cleaning the hydrogen cooler 8 with heavy dirt, the strong mode can be switched to, so that the water pressure is increased, and it is ensured that the dirt is thoroughly cleaned. The pressure adjustment and multi-mode design improve the operation convenience and reliability of the equipment.

Then the operator starts the water pump in the flushing trolley 1, goes to the waterproof front end cover 2, and holds the water gun 7 to clean the inside of the cooling coil of the hydrogen cooler 8. During the cleaning process, appropriate working mode can be selected according to the dirt level, and the pressure of the water gun 7 is controlled by adjusting the pressure valve and the manual valve. During cleaning, the rubber balls enter the cooling pipe from one side of the hydrogen cooler 8, and the rubber balls are cleaned by using high-pressure water flow impact and pushing. The other side of the hydrogen cooler 8 is provided with a recycling device to recycle the rubber balls. The dirty water after cleaning flows out through the waterproof rear end cover, is filtered through the filter screen, and is discharged out of the equipment through the water receiving groove 5 and the sewage outlet 6.
