[0002] Water-cooled units generally refer to centrifugal refrigeration units, specifically centrifugal refrigeration units for air conditioning (or centrifugal water chillers). These units consist of a centrifugal refrigeration compressor, evaporator, condenser, main motor, air extraction and recovery device, lubrication system, control cabinet, and starter cabinet.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-7 This invention provides a technical solution: an energy-saving water-cooled unit, including a separator 101, a condenser 102, an evaporator 103, and an electrical control cabinet 104. An annular plate 2 is installed inside the condenser 102. A moving component for moving the annular plate 2 and a guiding component for guiding its movement are also installed inside the condenser 102. An L-shaped plate 5 is slidably connected to the annular plate 2 via a sliding component. A driving component for driving the L-shaped plate 5 is installed between the L-shaped plate 5 and the annular plate 2. A spraying component for spraying descaling agent is installed on the L-shaped plate 5. A square plate 11 is fixed to the front side of the L-shaped plate 5. A tapping component for facilitating descaling is installed on the square plate 11. Through the cooperation of the spraying component, the tapping component, and the pushing component, descaling agent is sprayed, vibrated, and scraped at various locations on the inner wall of the condenser 102, effectively cleaning the dirt stored on the inner wall of the condenser 102, facilitating the energy-efficient operation of the water-cooled unit.

[0027] The moving assembly includes a first connecting plate 301 fixed to the inner wall of the annular plate 2. Two first fixing plates 303 are fixed inside the condenser 102. The first connecting plate 301 is located between the two first fixing plates 303. A threaded sleeve 302 is fixed on the first connecting plate 301. A threaded rod 304 is fixed between the two first fixing plates 303. The threaded sleeve 302 and the threaded rod 304 are threadedly engaged. A first motor 305 for driving the threaded rod 304 is mounted on the first fixing plate 303. The guiding assembly includes a second connecting plate 401 fixed to the inner wall of the annular plate 2. The condenser 102 has two first fixing plates 303 fixed inside. There are two second fixed plates 402, and a guide rod 403 is slidably connected to the second connecting plate 401. The guide rod 403 is fixed between the two second fixed plates 402. When the first motor 305 is started, the threaded rod 304 is driven to rotate. During the rotation of the threaded rod 304, the annular plate 2 is moved inside the condenser 102 by the mutual meshing transmission between the threaded rod 304 and the threaded sleeve 302 and the guiding effect of the guide rod 403 and the second connecting plate 401. The movement of the annular plate 2 facilitates the descaling operation at different locations inside the condenser 102.

[0028] The sliding assembly includes an annular groove 601 formed on the annular plate 2, a sliding block 602 slidably connected to the annular groove 601, and an L-shaped plate 5 fixed to the sliding block 602. The driving assembly includes a rotating shaft 701 rotatably connected to the L-shaped plate 5, a gear 702 fixed to one end of the rotating shaft 701, a gear ring 703 fixed on the annular plate 2, and the gear 702 and the gear ring 703 meshing with each other. A second motor 704 for driving the rotating shaft 701 is installed on the L-shaped plate 5. When the second motor 704 is started, the rotating shaft 701 and the gear 702 at one end of the rotating shaft 701 are driven to rotate. During the rotation of the gear 702, the L-shaped plate 5 is driven to move by the meshing transmission between the gear 702 and the gear ring 703. During the movement of the L-shaped plate 5, the L-shaped plate 5 slides around the annular plate 2 due to the guiding effect of the annular groove 601 and the sliding block 602.

[0029] The spraying assembly includes a mounting pipe 801 mounted on an L-shaped plate 5. A nozzle 802 is mounted at one end of the mounting pipe 801 facing the inner wall of the condenser 102, and a storage tank 803 is threaded onto the other end of the mounting pipe 801. A conveying assembly for liquid conveying is provided on the mounting pipe 801. The conveying assembly includes two one-way valves 901 installed inside the mounting pipe 801. The two one-way valves 901 are oriented from one end of the mounting pipe 801 facing the storage tank 803 to the other end. A fixing pipe 902 is mounted on the mounting pipe 801, located between the two one-way valves 901. A piston plate 903 is slidably connected and matched with it. A pressing assembly for pressing the piston plate 903 is provided on the rotating shaft 701. Through the pressing assembly, the pressing rod 1003 and the piston plate 903 reciprocate inside the fixed tube 902 as the rotating shaft 701 rotates. Since the conduction direction of the two one-way valves 901 is one end of the mounting tube 801 facing the storage tank 803 and the other end, the reciprocating motion of the piston plate 903 can draw the descaling agent stored in the storage tank 803 into the space between the two one-way valves 901 and spray it out from the nozzle 802 at one end of the mounting tube 801 through pressing.

[0030] The extrusion assembly includes a disc 1001 fixed on a rotating shaft 701. An extrusion rod 1003 is slidably connected to one end of a fixed tube 902. One end of the extrusion rod 1003 is located inside the fixed tube 902 and fixed to a piston plate 903. A plurality of rubber protrusions 1002 for pushing one end of the extrusion rod 1003 are arranged in a circular array on the disc 1001. A first spring 1004 is sleeved on the side wall of the extrusion rod 1003. The two ends of the first spring 1004 are respectively connected to the piston plate 903 and the fixed tube 902. The inner walls are connected, and the rotation of the rotating shaft 701 drives the disc 1001 to rotate synchronously. During the rotation of the disc 1001, each rubber protrusion 1002 abuts against one end of the extrusion rod 1003 in sequence. Through the abutting action of each rubber protrusion 1002 against one end of the extrusion rod 1003 and the reset action of the extrusion rod 1003 after being subjected to force by the first spring 1004, the extrusion rod 1003 and the piston plate 903 reciprocate inside the fixed tube 902 as the rotating shaft 701 rotates.

[0031] The striking assembly includes multiple round rods 1201 slidably connected to a square plate 11. A first transmission plate 1202 and a second transmission plate 1203 are fixed to both sides of the square plate 11, respectively. The two ends of each round rod 1201 are fixed to the first transmission plate 1202 and the second transmission plate 1203, respectively. The first transmission plate 1202 is located inside the L-shaped plate 5 and abuts against a rubber protrusion 1002. A striking rod 1205 is fixed to the second transmission plate 1203. A second spring 1204 is sleeved on the side wall of each round rod 1201. During the rotation of the disc 1001, the striking rod 1201 strikes the object through the rubber protrusions 1202. The interaction between the first transmission plate 1202 and the second springs 1204 on each round rod 1201 and the second springs 1204 on each round rod 1201 cause the first transmission plate 1202 to reciprocate back and forth with the rotation of the rotating shaft 701. During the movement of the first transmission plate 1202, the second transmission plate 1203 is driven to reciprocate synchronously through each round rod 1201. During the reciprocating movement of the second transmission plate 1203, the striking rod 1205 is driven to intermittently strike the inner wall of the condenser 102, which facilitates the removal and separation of the clumps of dirt after the descaling agent is sprayed on the inside of the condenser 102.

[0032] A scraper 13 is connected to the L-shaped plate 5 via a pushing assembly. The scraper 13 is pushed against the inner wall of the condenser 102 by the pushing assembly. The pushing assembly includes multiple sleeves 1401 fixed on the L-shaped plate 5. Each sleeve 1401 is slidably connected to a slide rod 1402. One end of each slide rod 1402 is fixed to the scraper 13. A third spring 1403 is sleeved on the side wall of each sleeve 1401. The two ends of the third spring 1403 are respectively connected to the scraper 13 and the L-shaped plate 5. The scraper 13 is guided by the sleeves 1401 and the slide rods 1402 after being subjected to force. The third springs 1403 facilitate pushing the scraper 13 against the inner wall of the condenser 102.

[0033] Working principle: During the use of the water-cooled unit, it is necessary to regularly descale the inside of the condenser 102 on the water-cooled unit. During the descaling operation, the second motor 704 is started, which drives the rotating shaft 701 and the gear 702 at one end of the rotating shaft 701 to rotate. During the rotation of the gear 702, the L-shaped plate 5 is driven to move by the meshing transmission between the gear 702 and the gear ring 703. During the movement of the L-shaped plate 5, the L-shaped plate 5 slides around the annular plate 2 by the guiding action of the annular groove 601 and the sliding block 602.

[0034] As the L-shaped plate 5 slides around the annular plate 2, the rotation of the rotating shaft 701 causes the disc 1001 to rotate synchronously. During the rotation of the disc 1001, each rubber protrusion 1002 sequentially abuts against one end of the extrusion rod 1003. Through the abutting action of each rubber protrusion 1002 against one end of the extrusion rod 1003 and the restoring action of the first spring 1004 on the extrusion rod 1003 after being subjected to force, the extrusion rod 1003 and the piston plate 903 rotate with the rotating shaft 701. The piston plate 903 reciprocates inside the fixed pipe 902. Since the two check valves 901 are aligned with the other end of the mounting pipe 801 facing the storage tank 803, the reciprocating motion of the piston plate 903 draws the descaling agent stored in the storage tank 803 between the two check valves 901. This agent is then expelled from the nozzle 802 at one end of the mounting pipe 801 through compression. Simultaneously, the L-shaped plate 5 slides, completing the spraying of descaling agent around the inner wall of the condenser 102. The disc 1... During the rotation of shaft 701, the first transmission plate 1202 reciprocates back and forth as the shaft rotates, due to the abutment of the rubber protrusions 1002 against the first transmission plate 1202 and the restoring effect of the second springs 1204 on each round rod 1201. During this movement, the second transmission plate 1203 reciprocates synchronously via the round rods 1201. During the process, the driving striking rod 1205 intermittently strikes the inner wall of the condenser 102, which facilitates the removal and separation of the clumps of dirt that have formed after the descaling agent is sprayed on the inside of the condenser 102. During the movement of the L-shaped plate 5, the pushing component pushes the scraper 13, which keeps the scraper 13 against the inner wall of the condenser 102 as the L-shaped plate 5 moves. The action of the scraper 13 against the inner wall of the condenser 102 makes it easier to clean the dirt on the inner wall of the condenser 102 more effectively.

[0035] During the cleaning process, the first motor 305 is started, which drives the threaded rod 304 to rotate. During the rotation of the threaded rod 304, the mutual meshing transmission between the threaded rod 304 and the threaded sleeve 302, as well as the guiding effect of the guide rod 403 and the second connecting plate 401 on the annular plate 2, allow the annular plate 2 to move inside the condenser 102. The movement of the annular plate 2 facilitates the descaling operation at different locations inside the condenser 102.
