Description

Technical Field

[0001] This utility model relates to the technical field of steam turbine condensers, specifically to a support base for a condenser hot well. Background Technology

[0002] A condenser is a heat exchanger that condenses steam from a steam turbine into water. A hot well is an important component of it. The hot well is installed in the lower part of the condenser shell and serves as a collection container for condensate.

[0003] To ensure the stability of the condenser, elastic supports are usually installed at the bottom of the hot well to accommodate the thermal expansion of the condenser. However, during operation, the condenser is prone to rotational displacement under external loads (such as pipe torque and circulating water pipe torque), causing the external load to be transferred to the low-pressure cylinder. Especially under extreme conditions (earthquakes, circulating water blind plate forces, etc.), this can harm the operation of the turbine unit and result in poor stability. Utility Model Content

[0004] The technical objective of this utility model is to address the shortcomings of the prior art by providing a support base for a condenser hot well that can both accommodate the thermal expansion of the condenser hot well and limit the rotational displacement of the condenser, thereby helping to ensure the stability of the steam turbine.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A support base for a condenser hot well, the support base having an elastic support and a rigid support corresponding to the hot well;

[0007] The height of the elastic support is adjustable;

[0008] The rigid support has a mounting part and a limiting part. The mounting part is used to connect with the hot well. The limiting part has a base and two sets of guide components disposed opposite to each other on the base. The base and the two sets of guide components form a straight guide groove. The mounting part is partially embedded in the guide groove and can move within the guide groove.

[0009] In the installed state, the support base has an elastic support that is clearance-fitted with the hot well, and the mounting part of the rigid support is connected to the hot well, and the mounting part abuts against the bottom of the guide groove of the limiting part.

[0010] In operation, the support base has the elastic support abutting against the hot well, the mounting part of the rigid support connected to the hot well, and the mounting part and the bottom of the guide groove of the limiting part are in clearance fit.

[0011] The aforementioned technical measures, through the combination of rigid and elastic supports, enable the rigid supports to bear loads during installation, facilitating the assembly and adjustment of the elastic supports. By adjusting the height of the elastic supports, they are brought into contact with the hot well, allowing them to bear loads during operation. The elastic supports can adapt to displacement and deformation caused by condenser thermal expansion, ensuring stable support of the condenser under different operating conditions and improving stability. Simultaneously, during operation, the mounting part of the rigid support is connected to the hot well, and the bottom of the guide groove of the mounting part and the limiting part are fitted with a clearance, allowing the straight guide groove to restrict the displacement direction caused by condenser thermal expansion, thus preventing condenser rotational displacement.

[0012] Furthermore, there are six elastic supports, four of which are evenly arranged along the circumferential direction of the support base, and the other two are symmetrically arranged in the middle of the support base along the length direction of the support base.

[0013] In the above-mentioned technical measures, four elastic supports are evenly arranged along the circumferential direction of the support base, and the other two elastic supports are symmetrically arranged in the middle of the support base along the length direction of the support base. This can evenly support the weight of the condenser, which helps to avoid excessive local stress and improves the stability of the support base.

[0014] Furthermore, the elastic support has a first base plate, a first top plate, a spring, a screw, a movable plate, and a pad;

[0015] The top of the spring is connected to the first top plate, and the bottom of the spring is connected to the movable plate;

[0016] The screw is threadedly connected to the movable plate, and the bottom of the screw abuts against the first base plate. During the rotation of the screw, the movable plate moves up and down.

[0017] In operation, the support base has a first top plate that abuts against the hot well, and multiple pads that abut against the moving plate and the first bottom plate are arranged between the moving plate and the first bottom plate, respectively.

[0018] In the above technical measures, during the installation of the support base, the moving plate is moved upward by rotating the screws until the first top plate abuts against the hot well. Then, the moving plate and the first bottom plate are abutted by pads respectively, and the screws can be removed. The moving plate and the first bottom plate are connected by the pads, which helps to prevent the screws from rotating accidentally when the support base is in operation, and helps to improve stability.

[0019] Furthermore, the elastic support has multiple springs, which are divided into multiple spring groups, and the multiple spring groups are arranged at intervals along the length direction of the elastic support.

[0020] Each spring group includes at least three springs, and the springs in each spring group are spaced apart along the width direction of the elastic support and connected to the same movable plate.

[0021] The above-mentioned technical measures, through the setting of multiple sets of springs, help to distribute the load more evenly, reduce local stress concentration, and improve the support capacity of the elastic support.

[0022] Furthermore, the elastic support has multiple screws, and these screws are evenly arranged along the circumferential direction of the movable plate.

[0023] The above-mentioned technical measures facilitate the adjustment of the height of the moving plate by setting multiple screws, and the even arrangement of multiple screws helps to improve stability.

[0024] Furthermore, the first base plate has a recessed limiting groove corresponding to the screw;

[0025] The bottom of the screw abuts against the bottom surface of the limiting groove.

[0026] The above-mentioned technical measures, by setting a recessed limiting groove on the first base plate corresponding to the screw, can help prevent the screw from being accidentally displaced during rotation and help ensure the stability of the screw rotation.

[0027] Furthermore, there are four rigid supports, and the four rigid supports are evenly arranged along the circumferential direction of the support base.

[0028] In the above-mentioned technical measures, the four rigid supports are evenly arranged along the circumferential direction of the support base, which helps to improve the support capacity of the rigid supports; at the same time, it can restrict the thermal expansion displacement direction of the condenser in four directions simultaneously.

[0029] Furthermore, the mounting portion of the rigid support has an upper and lower connected support plate and a connecting plate, the support plate being used to connect with the hot well, and the connecting plate being embedded in the guide groove.

[0030] Furthermore, the base of the limiting part has a second top plate, a second bottom plate, and a stiffening plate;

[0031] There are multiple stiffening plates, which are arranged in a crisscross pattern between the second top plate and the second bottom plate, and the stiffening plates are respectively connected to the second top plate and the second bottom plate.

[0032] In the above-mentioned technical measures, multiple stiffening plates are arranged in a crisscross pattern between the second top plate and the second bottom plate, which helps to enhance the structural strength of the base and improve its stability.

[0033] Furthermore, the guide assembly of the limiting part has multiple guide plates, which are disposed on the second top plate and are arranged at intervals along the length direction of the second top plate.

[0034] One or more technical solutions provided by this utility model have at least the following technical effects or advantages:

[0035] This invention combines a rigid support and an elastic support. In the installation state, the rigid support bears the load, facilitating the assembly and adjustment of the elastic support. By adjusting the height of the elastic support, it comes into contact with the hot well, allowing it to bear the load during operation. The elastic support can adapt to displacement and deformation caused by thermal expansion, ensuring stable support of the condenser under different operating conditions and improving stability. Simultaneously, in the operating state, the mounting part of the rigid support connects to the hot well, and the bottom of the guide groove of the mounting part and the limiting part are fitted with a clearance. This allows the straight guide groove to restrict the displacement direction caused by thermal expansion of the condenser, preventing condenser rotational displacement. Attached Figure Description

[0060] Among them, the pad 16 comes in a variety of different sizes, which helps to adapt to different working conditions.

[0061] The elastic support 1 has multiple springs 13, which are divided into multiple spring groups, and the multiple spring groups are arranged at intervals along the length direction of the elastic support 1.

[0062] Each spring group includes at least three springs 13, and the springs 13 in each spring group are arranged at intervals along the width direction of the elastic support 1 and connected to the same movable plate 15.

[0063] Wherein, the length direction of the elastic support 1 is the length direction B1 of the elastic support, and the width direction of the elastic support 1 is the width direction C1 of the elastic support.

[0064] The elastic support 1 has multiple screws 14, and these screws 14 are evenly arranged along the circumferential direction of the movable plate 15.

[0069] The base 3 of the limiting part has a second top plate 31, a second bottom plate 32 and a stiffening plate 33;

[0070] There are multiple stiffening plates 33, which are arranged in a crisscross pattern between the second top plate 31 and the second bottom plate 32, and the stiffening plates 33 are respectively connected to the second top plate 31 and the second bottom plate 32.

[0074] During operation, when the condenser deforms or shifts due to thermal expansion, the spring 13 will be further compressed or rebound. At the same time, due to the clearance fit between the mounting part of the rigid support 2 and the bottom of the guide groove of the limiting part, the direction of displacement is restricted, which helps to prevent the condenser from rotating. This ensures that the support base can stably support the hot well under different operating conditions.
