Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a stable structure of a condenser. Background Art

[0002] A condenser is a heat exchanger that condenses the exhaust steam of a steam turbine into water. In addition to condensing the exhaust steam of a steam turbine into water for filtration and reuse, the condenser can also establish or maintain a vacuum at the exhaust of the steam turbine. Condensers are mainly used in the power unit of steam turbines. Condenser air leakage has a profound impact on the safe and economical production of steam turbine generator sets. Therefore, regular tightness tests are required to timely monitor the leakage of the condenser.

[0003] The condenser is usually fixed with holes in the ground and bolts. The condenser needs to keep the equipment stable during the tightness test. The bolts will gradually loosen during long-term use due to the continuous vibration of the condenser during operation. Loose bolts will cause the condenser to shake more during operation, making the condenser unable to operate stably. The results of the tightness test of an unstable condenser will be inaccurate, and the erroneous results make it impossible to accurately judge the leakage condition of the condenser.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0040] The utility model provides a stable structure of a condenser. Figures 1 to 5 The present invention provides an embodiment of a stable structure of a condenser.

[0041] See also Figure 1The stable structure of the condenser includes a mounting seat 2, a fixing assembly and a lifting assembly. The mounting seat 2 forms a accommodating cavity, in which a condenser body 1 is movably mounted. A limiting mechanism 3 is arranged in the accommodating cavity, and the limiting mechanism 3 is used to limit the condenser body 1. The fixing assembly is arranged in the accommodating cavity, and the fixing assembly is used to prevent the condenser body 1 from moving. The lifting assembly is arranged in the accommodating cavity, and the lifting assembly is used to drive the condenser body 1 to enter or leave the accommodating cavity.

[0042] When fixed by bolts, the bolts will be affected by the vibration generated by the condenser body 1 itself during operation, and gradually loosen in the continuous vibration. Therefore, maintenance personnel are required to regularly check the tightness of the bolts to ensure the stable operation of the condenser body 1, which increases the labor cost. The loosening of the bolts will also cause the operation of the condenser body 1 to be unstable. Therefore, the bolt fixing method is abandoned during the fixing process of the condenser body 1, so that the condenser body 1 will not be unable to run stably due to the loosening of the bolts. By opening a suitable size of the accommodating cavity for placing the condenser body 1, it is difficult for the condenser body 1 to shake greatly back and forth and left and right after being fixed. It can only shake in the small gap between the condenser body 1 and the wall in the accommodating cavity, which is difficult to affect the operation of the condenser body 1. At the same time, a lifting component is arranged in the accommodating cavity to lift or lower the condenser body 1, so that the condenser body 1 can be conveniently placed in the accommodating cavity or detached from the accommodating cavity, and the condenser body 1 is restricted by the fixing component, so that the condenser body 1 is difficult to move, thereby completing the fixed installation of the condenser body 1.

[0043] The fixing work of the condenser body 1 is mainly to fix the base plate of the condenser body 1 close to the ground. Therefore, the part of the condenser body 1 placed in the accommodating cavity is also the base plate. Therefore, the length and width of the accommodating cavity should be greater than the length and width of the base plate of the condenser body 1, so that the base plate of the condenser body 1 can be placed in the accommodating cavity. However, in order to avoid a large gap between the base plate and the wall of the accommodating cavity after the base plate enters the accommodating cavity, which causes the condenser body 1 to shake significantly, it is most appropriate to set the gap between the base plate and the accommodating cavity to within one millimeter, so that the base plate can enter the accommodating cavity while not causing the condenser body 1 to shake a certain distance. In addition, a rubber pad can be set on the inner wall of the accommodating cavity to prevent the condenser from colliding with the wall of the accommodating cavity when shaking, causing damage to the base plate or the mounting seat 2.

[0044] Therefore, in the technical solution provided by the utility model, the fixing component is arranged in the accommodating cavity, the fixing component is used to prevent the condenser body 1 from moving, the lifting component is arranged in the accommodating cavity, the lifting component is used to drive the condenser body 1 to enter or leave the accommodating cavity, the condenser to be fixed is moved into the accommodating cavity by the lifting component, and the condenser is fixed in the accommodating cavity by the fixing component, so that the condenser is difficult to move in the accommodating cavity, thereby making the condenser operate stably.

[0045] Please also read Figures 2 to 4 The fixing assembly includes a motor 301 and a limit member 303. The motor 301 is arranged in the mounting seat 2. The motor 301 is driven and connected to a rotating shaft 302 located in the accommodating cavity. The motor 301 is used to drive the rotating shaft 302 to rotate. The limit member 303 is arranged on the rotating shaft 302. The limit member 303 is located in the condenser body 1. The limit member 303 is used to prevent the condenser body 1 from moving.

[0046] When restricting the condenser body 1 located in the accommodating cavity, the motor 301 is started, the motor 301 drives the rotating shaft 302 to rotate through the output shaft, and drives the limiting member 303 to rotate through the rotating shaft 302. The limiting member 303 is turned off after the rotating shaft 302 rotates a certain number of times, and the limiting member 303 located in the condenser body 1 can restrict the condenser body 1 at this time, making it difficult for the condenser body 1 to move, thereby stably fixing the condenser body 1 in the accommodating cavity, so that the condenser body 1 can stably operate in the accommodating cavity.

[0047] The function of the limit member 303 is to limit the movement of the condenser body 1. The limit member 303 enters the interior of the condenser body 1 under the drive of the motor 301, and at this time, the condenser body 1 cannot be separated from the limit member 303 no matter how much it moves in which direction. Then a part of the limit member 303 is connected to the mounting seat 2 and other immovable parts, so that the condenser body 1 is basically unable to move after being restricted by the limit member 303. When the condenser body 1 is unable to move, the shaking generated by the operation of the condenser body 1 will be limited, thereby reducing the impact of the shaking generated by the operation of the condenser body 1 on the condenser body 1 to a minimum. The stable operation of the condenser body 1 ensures that the results of the tightness test will not be affected, thereby ensuring the accuracy of the results, so that the staff can accurately judge the leakage condition of the condenser through the tightness test.

[0048] Furthermore, the condenser body 1 is provided with a connecting groove for the rotating shaft 302 to be plugged in, and the condenser body 1 is provided with a first limiting groove and a second limiting groove for the limiting member 303 to be slidably connected, the first limiting groove extends toward the motor 301, and the second limiting groove is fan-shaped and provided on the condenser body 1, and the first limiting groove, the second limiting groove and the connecting groove are connected to each other.

[0049] The connecting groove and the first limiting groove allow the rotating shaft 302 and the limiting member 303 to slide into the interior of the condenser body 1 after the condenser body 1 is placed in the accommodating cavity. When the limiting member 303 slides to the connection point between the first limiting groove and the second limiting groove, the motor 301 can be started, and the motor 301 drives the limiting member 303 to rotate through the rotating shaft 302. The limiting member 303 enters the second limiting groove after the rotating shaft 302 rotates. The second limiting groove is located inside the condenser body 1 and can only be entered through the connection point with the first limiting groove. As a result, the limiting member 303 cannot escape from the condenser body 1 through the second limiting groove after entering the second limiting groove, thereby realizing the restriction of the condenser body 1. At the same time, the second limiting groove is fan-shaped, so that the limiting member 303 can move in the second limiting groove when the rotating shaft 302 rotates, so that the limiting member 303 can penetrate into the second limiting groove and stably restrict the condenser body 1.

[0050] In order to ensure that the rotating shaft 302 rotates stably in the mounting seat 2 and does not drive the mounting seat 2 to rotate together during the rotation process, a mounting groove connected to the accommodating cavity is opened in the mounting seat 2, a bearing is arranged in the mounting groove, and the rotating shaft 302 is fixed inside the bearing.

[0051] The shaft 302 is fixed on the mounting base 2 by setting a bearing, and the shaft 302 can rotate by itself. At the same time, the bearing also supports the shaft 302, so that the gravity of the shaft 302 will not be all pressed on the motor 301, thereby avoiding the problem of the output shaft being skewed due to long-term pressure on the motor 301, thereby allowing the motor 301 to be used stably and also increasing the service life of the motor 301.

[0052] In order to facilitate the condenser body 1 to enter or leave the accommodating chamber, a structure capable of driving the condenser body 1 to move is provided, so that the condenser body 1 can smoothly enter or leave the accommodating chamber with the cooperation of the structure.

[0053] Specifically, in an embodiment of the utility model, the lifting assembly includes a driving member 304, a slider 306 and a slide groove 307. The driving member 304 drives the connected lifting plate 305. The driving member 304 is used to drive the lifting plate 305 to rise or fall, so as to drive the condenser body 1 to separate from or enter the accommodating cavity. One of the slider 306 and the slide groove 307 is arranged on the lifting plate 305, and the other is arranged in the mounting seat 2. The slider 306 is slidably connected in the slide groove 307. The slider 306 and the slide groove 307 are used to limit the moving distance of the lifting plate 305.

[0054] When the condenser body 1 needs to be placed into the accommodating chamber, the condenser body 1 is placed on the lifting plate 305, and the side of the condenser body 1 is aligned with the inner wall of the accommodating chamber. Then the driving member 304 is started to drive the lifting plate 305 to descend into the accommodating chamber, thereby driving the condenser body 1 on the lifting plate 305 to move into the accommodating chamber, so that the condenser body 1 gradually enters the accommodating chamber. At the same time, the slider 306 will slide in the slide groove 307 with the movement of the lifting plate 305. When the lifting plate 305 stops moving, the condenser body 1 can be placed, so that the condenser body 1 enters the accommodating chamber.

[0055] The driving member 304 is mainly used to drive the lifting plate 305 to perform linear motion, so that the lifting plate 305 can move up and down, thereby lifting the condenser body 1 or driving the condenser body 1 into the accommodating chamber. Therefore, the driving member 304 can be a cylinder or an electric drive or other device that directly drives the lifting plate 305 to perform linear motion, or it can be a motor that drives the threaded rod to rotate, and then the threaded rod drives the threaded sleeve to move up and down, and then drives the lifting plate 305 to move downward through the movable sleeve, which indirectly drives the lifting plate 305 to perform linear motion.

[0056] Furthermore, a positioning component 4 is provided on the lifting plate 305, and the positioning component 4 is used to limit the placement position of the condenser body 1. When the condenser body 1 is placed on the lifting plate 305, the side of the condenser body 1 needs to be aligned with the inner wall of the accommodating cavity. It is troublesome to align it completely manually by the staff, and the alignment cannot be guaranteed. The alignment can only be achieved by gradual adjustment during the descent of the condenser body 1. Therefore, an auxiliary positioning positioning component 4 is provided, so that the staff can quickly complete the positioning work and align the side of the condenser body 1 with the inner wall of the accommodating cavity.

[0057] Specifically, in the technical solution of the present invention, the positioning assembly 4 includes a positioning seat 401 and a movable plate 404, the positioning seat 401 is arranged on the lifting plate 305, and a plurality of first springs 402 are arranged on the positioning seat 401, the movable plate 404 is arranged on a plurality of the first springs 402, and a positioning block 403 inserted into the condenser body 1 is arranged on the movable plate 404, and the positioning block 403 is used to determine the placement position of the condenser body 1.

[0058] A positioning groove matched with the positioning block 403 is opened on the condenser body 1. After the condenser body 1 is placed on the lifting plate 305, the positioning block 403 is aligned with the positioning groove and the positioning block 403 is inserted into the positioning groove. When the positioning blocks 403 on the lifting plate 305 are all inserted into the positioning groove, the side of the condenser body 1 is aligned with the inner wall of the accommodating cavity. At this time, the condenser body 1 can be driven into the accommodating cavity by the lifting assembly to complete the placement work. The positioning assembly 4 assists the staff to quickly determine the placement position of the condenser body 1 on the lifting plate 305, so that the staff can place the condenser body 1 into the accommodating cavity without continuously adjusting the position of the condenser body 1 during the descent of the condenser body 1.

[0059] See also Figure 5 A reinforcement component 5 is provided on the mounting seat 2, and the reinforcement component 5 is used to limit the movement of the condenser body 1.

[0060] In order to further reduce the shaking amplitude of the condenser body 1 during operation, a structure for limiting the condenser body 1 is provided on the mounting seat 2, so that the condenser body 1 is difficult to shake up and down.

[0061] Specifically, in the technical solution of the present invention, the reinforcement assembly 5 includes an auxiliary box 503, a reinforcement plate 501 and a limit plate 504, the auxiliary box 503 is arranged on the mounting seat 2, and a plurality of second springs 502 are arranged in the auxiliary box 503, the reinforcement plate 501 is arranged on the side of the second spring 502 close to the condenser body 1, and the reinforcement plate 501 is slidably connected in the auxiliary box 503, the reinforcement plate 501 is used to prevent the condenser body 1 from detaching from the accommodating cavity, the limit plate 504 is slidably connected in the auxiliary box 503, and the limit plate 504 is inserted in the reinforcement plate 501, and the limit plate 504 is used to limit the position of the reinforcement plate 501.

[0062] After the condenser body 1 is placed in the accommodating cavity and fixed by the fixing assembly, the limiting plate 504 is pulled to separate the limiting plate 504 from the reinforcing plate 501. After the limiting plate 504 separates from the reinforcing plate 501, the second spring 502 pushes the reinforcing plate 501 toward the condenser body 1, so that the part of the reinforcing plate 501 extending out of the auxiliary box 503 is located on the upper side of the accommodating cavity, and at the same time, the part of the reinforcing plate 501 extending out of the auxiliary box 503 is in contact with the upper side of the bottom plate of the condenser body 1 located in the accommodating cavity, so that The bottom plate of the condenser body 1 located in the accommodating cavity cannot be separated upward from the accommodating cavity, and thus the condenser body 1 cannot be separated from the accommodating cavity. When the condenser body 1 needs to be taken out, the reinforcement plate 501 is completely pushed into the auxiliary box 503, and the limit plate 504 is inserted through the auxiliary box 503 into the reinforcement plate 501, so that the reinforcement plate 501 is restricted inside the auxiliary box 503 and cannot be separated, thereby contacting the restriction on the upper side of the bottom plate, so that the condenser body 1 can be lifted upward by the lifting assembly to separate from the accommodating cavity.

[0063] In order to prevent the reinforcing plate 501 from being completely separated from the auxiliary box 503 under the push of the second spring 502, a limiting block is set on one of the reinforcing plate 501 and the auxiliary box, and a limiting groove is set on the other, and the limiting block is slidably connected in the limiting groove. The movement distance of the reinforcing plate 501 is limited by the cooperation of the limiting block and the limiting groove, thereby preventing the reinforcing plate 501 from being completely pushed out of the auxiliary box 503 by the second spring 502. At the same time, two fixing grooves for the limiting block to be inserted can be opened on the reinforcing plate 501, and one fixing groove is used to insert the reinforcing plate 501. 01 is limited to a state where a portion of the reinforcement plate 501 is located outside the auxiliary box 503, and the other fixed groove is used to completely confine the reinforcement plate 501 inside the auxiliary box 503. It can also avoid the problem that the reinforcement plate 501 is completely pushed out of the auxiliary box 503 by the second spring 502 and loses the restriction. In order to ensure that the reinforcement plate 501 can restrict the bottom plate from moving upward, it is necessary to restrict the reinforcement plate 501 on the bottom plate. Therefore, a portion of the reinforcement plate 501 needs to be located in the auxiliary box 503 to restrict the reinforcement plate 501, so that the reinforcement plate 501 cannot move arbitrarily and separate from the bottom plate.

[0064] The condenser body 1 needs to be moved during the installation, disassembly and transportation process, but because the condenser body 1 is usually large in size, a crane is needed to complete the movement of the condenser body 1. The erection and installation of the crane require a lot of time and money, and the condenser body 1 cannot be moved after the crane puts it down, which makes it inconvenient for the staff to make more precise adjustments to the installation position of the condenser body 1. Therefore, a plurality of universal wheels are provided on the condenser body 1, and the universal wheels are used to drive the condenser body 1 to move.

[0065] By arranging a plurality of universal wheels on the side of the condenser body 1 facing the ground, the movement of the condenser body 1 only requires the staff to push and adjust the forward direction. At the same time, with the help of the universal wheels, the condenser body 1 can be moved in a small range, making the placement of the condenser body 1 more accurate.

[0066] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
