Abstract

The utility model relates to a control loop structure for a small vertical type water turbine set, which comprises a control loop body, and is characterized in that the control loop body is symmetrically welded with connecting blocks which are processed with connecting holes along the axial direction of the control loop body. Therefore, the control loop structure is extremely simplified, and compared with the traditional structure, at least 24 welding seams are reduced, thus saving both work time of processing and using materials, quickening production progress, and decreasing the cost of workpieces; and the height of the control loop is lower than that of the traditional structure, the rigidity is good, and the use is safe and reliable.

Description

Minitype vertical type water wheels unit control ring structure

Technical field

The utility model belongs to the water turbine technical field of power generation, particularly relates to a kind of minitype vertical type water wheels unit control ring structure.

Background technique

Control ring is the vitals in the turbine gate mechanism, and it is the active force that is used to transmit servomotor, and rotates the annular element of stator by driving mechanism.Traditional control ring all is a welded-steel plate construction, as shown in Figure 1, is shaped on two frame structures on control ring body top, is processed with attachment hole on the frame structure, and this frame structure is welded with 12 block plates at least, connects two servomotors by pull bar; Above-mentioned control ring structure is applicable to relatively large unit, and (unit of runner diameter D1≤4m) adopts this structure more complicated that seems, makes more numerous and diversely, and cost is also higher for less.

Summary of the invention

The utility model provides a kind of simple in structure, easily manufactured, safe and reliable and minitype vertical type water wheels unit control ring structure that cost is low for solving the technical problem that exists in the known technology.

The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of minitype vertical type water wheels unit control ring structure comprises the control ring body, it is characterized in that: be symmetrically welded with contiguous block on the described control ring body, contiguous block upper edge control ring body axis direction is processed with attachment hole.

Advantage and the good effect that the utlity model has are: be symmetrically welded with contiguous block because the utility model adopts directly on the control ring body, contiguous block upper edge control ring body axis direction is processed with attachment hole.Make structure extremely simplify like this, reduced by at least 24 weld seams, promptly saved machining period, saved the use material again, improved manufacturing schedule, reduced the workpiece cost, and the control ring height is lower than conventional construction, and good rigidity, safe and reliable.

Description of drawings

Fig. 1 is existing control ring structural representation;

Fig. 2 is the utility model structural representation;

Fig. 3 is the A-A sectional view among Fig. 2.

Among the figure: 1, control ring body; 2, contiguous block; 3, attachment hole.

Embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

Embodiment:

See also Fig. 2 and Fig. 3, a kind of minitype vertical type water wheels unit control ring structure, comprise control ring body 1, be symmetrically welded with contiguous block 2 on the described control ring body 1, the contiguous block that contiguous block 2 upper edge control ring body axis directions are processed with in attachment hole 3. present embodiments adopts round steel to replace, get final product adding only to need man-hour round steel directly welded together with the control ring body, round steel is that center hole uses as attachment hole. so the utility model makes structure extremely simplify, compare with conventional construction and to have reduced by 24 weld seams at least, promptly saved machining period, saved the use material again, improved manufacturing schedule, reduced the workpiece cost, and the control ring height is lower than conventional construction, and good rigidity, it is safe and reliable.

In sum, content of the present utility model is not limited in the above-described embodiment, knowledgeable people in the same area can propose other embodiment easily within technological guidance's thought of the present utility model, but this embodiment is included within the scope of the present utility model.

Claims

1. a minitype vertical type water wheels unit control ring structure comprises the control ring body, it is characterized in that: be symmetrically welded with contiguous block on the described control ring body, contiguous block upper edge control ring body axis direction is processed with attachment hole.
