Description

Technical Field

[0001] This utility model belongs to the field of condenser technology, and specifically relates to a positioning device for condensers. Background Technology

[0002] In a thermal power plant, the steam-water cycle involves heating water in a boiler into high-temperature, high-pressure steam, which drives a steam turbine to generate electricity. The exhaust steam from the turbine is condensed into condensate in a condenser, pumped out by a condensate pump, passes through a low-pressure heater to a deaerator for deoxygenation, and then is pumped out by a feedwater pump, passes through a high-pressure heater, and returns to the boiler for reheating, completing the steam-water cycle.

[0003] The condenser is one of the key pieces of equipment in a thermal power plant. Its main functions are to condense the low-pressure steam discharged from the turbine into water; to help maintain the turbine's vacuum and ensure its thermal efficiency; and to remove heat from the steam through external cooling water, thus completing the energy conservation process. The main principle is that the condenser achieves condensation through heat exchange between the steam and the external cooling water. After entering the condenser, the steam comes into contact with the cooling water pipes, releases heat, and condenses into water. The external cooling water absorbs the heat released from the condensation of the turbine exhaust steam and then exits the condenser. Existing condensers are bulky and heavy, and their installation and disassembly are time-consuming and labor-intensive, delaying equipment maintenance schedules. Therefore, a positioning device for the condenser group in a thermal power plant is proposed to address these issues. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] Currently, the common method for installing condensers is to place them at 0 meters above the ground level in the turbine hall, extending upwards to the turbine exhaust space. This method is inconvenient for condenser installation and lacks a stable support base for the condenser during operation. The condensers are also too large, making on-site installation cumbersome, time-consuming, and labor-intensive, thus having inherent drawbacks.

[0038] This application provides a positioning device for a condenser, referencing... Figure 1 It includes the condenser body 1 and the base 2;

[0039] A connecting component 3 is provided between the condenser body 1 and the base 2;

[0040] The connecting assembly 3 includes a connector 31 and a support plate 32. One end of the connector 31 is fixedly connected to the condenser body 1, and the support plate 32 is fixedly installed on the top of the base 2. A connecting groove matching the connector 31 is provided on the support plate 32.

[0041] The base 2 is also provided with a positioning mechanism 4 for fixing the connector 31.

[0042] When the condenser body 1 is hoisted and assembled, the connector 31 on the condenser body 1 is aligned with the support plate 32 on the base 2, and the condenser body 1 is supported by the connecting groove on the support plate 32; then the connector 31 is fixed by driving the positioning mechanism 4, thereby improving the connection stability between the connector 31 and the support plate 32.

[0043] This application provides support for the condenser body 1 by setting up a connector 31 and a support plate 32, while improving the stability of the condenser body 1 installation through a positioning mechanism 4, and facilitating the disassembly and assembly of the condenser body 1. This not only solves the problem of difficult disassembly and assembly of the condenser body 1 during maintenance, but also provides support for the stable operation of the condenser body 1. At the same time, it can effectively and accurately position the condenser body 1 during installation, ensure leveling of the bottom surface of the condenser body 1 during assembly, improve the load-bearing stability of the plant floor on the condenser body 1, and effectively improve the efficiency of the installation and maintenance of the condenser body 1.

[0044] In one embodiment of the present invention, the connecting member 31 includes two sets, and the two sets of connecting members 31 are symmetrically distributed on both sides of the condenser body 1.

[0045] By symmetrically arranging two connectors 31, the positioning mechanism 4 simultaneously fixes the two connectors 31, which not only improves the support stability of the support plate 32 on the connectors 31 and the condenser body 1, but also further improves the connection stability of the connectors 31.

[0046] In one embodiment of the present invention, the connector 31 includes a connector 311 and an alignment plate 312; the connector 311 is fixedly connected to the condenser body 1; one end of the alignment plate 312 is fixedly connected to the connector 311, and the other end of the alignment plate 312 is connected to the connector groove.

[0047] The connecting seat 311 is part of the condenser body 1. The alignment plate 312 is detachably connected to the connecting seat 311. A connection structure matching the positioning mechanism 4 can be set on the alignment plate 312. The alignment plate 312 is installed when the condenser body 1 needs it, which improves the convenience of disassembly and assembly.

[0048] In one embodiment of this utility model, reference is made to... Figure 2 The positioning mechanism 4 includes a bearing plate 41 and a lead screw assembly 42; the bearing plate 41 is fixedly installed on the base 2, and the lead screw assembly 42 is rotatably installed on the bearing plate 41; a driving component 43 is installed at one end of the lead screw assembly 42, and a fixing component 44 is sleeved on the lead screw assembly 42.

[0049] After the connector 31 is connected to the connecting groove, the drive member 43 drives the lead screw assembly 42 to rotate, thereby the lead screw assembly 42 drives the fixing member 44 to move toward the connector 31, thereby fixing the connector 31.

[0050] In one embodiment of this utility model, reference is made to... Figure 2 The bearing plate 41 includes two sets, and the two sets of bearing plates 41 and the two sets of connecting parts 31 are arranged in a cross shape; each set of bearing plates 41 is rotatably connected to a lead screw assembly 42 at one opposite end, and a connecting rod 45 is fixedly connected between the two sets of lead screw assemblies 42; the two sets of lead screw assemblies 42 have opposite rotation directions.

[0051] When the lead screw assembly 42 rotates, the two sets of lead screw assemblies 42 move towards or away from each other at the same time, thereby driving the fixing member 44 toward or away from the connecting member 31, thus fixing or disengaging the connecting member 31.

[0052] In one embodiment of this utility model, reference is made to... Figure 2The fixing component 44 includes a movable plate 441 and a push plate 442; two sets of movable plates 441 are respectively sleeved on two sets of lead screw assemblies 42, and push plates 442 are connected to both ends of the movable plates 441 facing the two alignment plates 312; an insert plate 443 is fixedly connected to one end of the push plate 442 facing the corresponding alignment plate 312, and a traction plate 444 is rotatably connected between the push plate 442 and the movable plate 441; a slot 445 is provided on the alignment plate 312 to cooperate with the insert plate 443; a stabilizing plate 6 is fixedly connected to each movable plate 441 near the bearing plate 41, and the stabilizing plate 6 is slidably inserted into the bearing plate 41.

[0053] The driving component 43 drives the lead screw assembly 42 to rotate; the two sets of lead screw assemblies 42 rotate in opposite directions, thereby driving the two moving plates 441 to move toward the connector 31. The moving plates 441 drive the push plate 442 and the insertion plate 443 to move toward the connector 31 through the traction plate 444, so that the insertion plate 443 enters the slot 445 opened in the alignment plate 312, thereby fixing the connector 31. When the moving plate 441 moves along the lead screw body 421, it slides on the bearing plate 41 through the stabilizing plate 6, which on the one hand restricts the rotation of the moving plate 441 with the lead screw assembly 42, and on the other hand further improves the stability of the movement of the moving plate 441.

[0054] This application reduces the number of bolts and flanges in the support design, and reduces unnecessary fixed parts during assembly and disassembly through the combined mechanical design of moving plate 441, push plate 442, and traction plate 444. The assembly is simple and the operation is convenient and easy to learn.

[0055] In one embodiment of this utility model, reference is made to... Figure 2 Each of the lead screw assemblies 42 includes two lead screw bodies 421 with opposite rotation directions; each lead screw body 421 is fitted with a movable plate 441.

[0056] By setting two lead screw bodies 421 on one side, a push plate 442 is connected to each end of the two moving plates 441, thereby improving the stability of the push plate 442 during movement.

[0057] In one embodiment of this utility model, reference is made to... Figure 2 and Figure 3 The driving component 43 includes a rotating rod 431 and a handle 432. One end of the rotating rod 431 is fixedly connected to one of the lead screw assemblies 42, and the other end of the rotating rod 431 is fixedly connected to the handle 432. A stop rod 433 is slidably connected to the handle 432, and a plurality of stop grooves 434 corresponding to the stop rod 433 are provided on the bearing plate 41.

[0058] When fixing the connector 31, the handle 432 rotates the screw rod 431, which drives the lead screw assembly 42 at one end to rotate. The lead screw assembly 42 drives the connecting rod 45 and the lead screw assembly 42 at the other end to rotate in the opening on the bearing plate 41. Due to the restriction of the stabilizing plate 6, the moving plate 441 moves horizontally along the lead screw, so that the moving plate 441 drives the insert plate 443 to move toward the connector 31. After the insert plate 443 fixes the connector 31, the moving stop rod 433 moves into the corresponding stop groove 434, so that the positions of the moving plate 441 and the insert plate 443 are fixed.

[0059] In one embodiment of this utility model, reference is made to... Figure 3 The end of the stop rod 433 facing the stop groove 434 is fixedly connected to an anti-detachment block 435, and a spring 436 is sleeved between the anti-detachment block 435 and the handle 432.

[0060] By setting an anti-detachment block 435, the stop rod 433 is prevented from detaching from the handle 432 during movement. By setting a spring 436, after the stop rod 433 enters the stop groove 434, the spring 436 abuts the anti-detachment block 435 against the bearing plate 41, improving the connection stability between the stop rod 433 and the stop groove 434. At the same time, the spring 436 can generate a horizontal outward thrust on the connecting seat 311 and the alignment plate 312 of the condenser body 1. The spring 436 can continuously lock this outward thrust, effectively suppressing the slight horizontal shaking of the condenser caused by the turbulence and rolling of condensate in the condenser.

[0061] In one embodiment of this utility model, reference is made to... Figure 1 The base 2 has multiple support legs 5 fixedly connected to its bottom, and all support legs 5 are inclined outwards.

[0062] By tilting the support legs 5 outwards, forming a V-shape with the left and right support legs 5, the support stability of the support legs 5 is improved.

[0063] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
