Abstract
The utility model relates to a kind of multi-stage pressure regulating room arrangement of power station, comprise the overall multiple sub-surge-chamber in being staggeredly arranged up and down, the sub-surge-chamber be positioned at bottom is connected with diversion tunnel, be communicated with by vestibule between adjacent two sub-surge-chambers, described vestibule comprises the main vestibule being communicated with adjacent two sub-surge-chambers and the auxiliary vestibule being communicated with neighbouring two main vestibules, with the first valve on described auxiliary vestibule; Be connected with equalizing main between described sub-surge-chamber, described equalizing main be provided with the second valve.Common high side wall surge-chamber is changed into the multilevel hierarchy of multiple low abutment wall surge-chamber by the utility model, arranges rational vestibule and equilibrium pressure structure, effectively improves the hydraulic connection efficiency between surge-chamber, strengthens overall hydraulic action.
Description
Technical field
The utility model relates to Hydropower Project technical field, particularly the arrangement of surge-chamber in power station.
Background technology
Surge-chamber in power station is general to be built according to massif country rock, and in large hydropower station, the edge wall of surge-chamber is higher, is namely referred to as high side wall surge-chamber.The abutment wall stability of high side wall surge-chamber is not high, the high side wall particularly built according to bad geological conditions, surge-chamber construction period and its stability of run duration poorer, thus affect the layout of large-scale run-of-river power station.
Have arrangement high side wall surge-chamber being transformed into multiple low abutment wall surge-chamber at present, it solves the stability problem of high side wall to a certain extent, but the shortcoming also existed is, the hydraulic connection efficiency between each surge-chamber is not high, and overall hydraulic action has to be reinforced.
Utility model content
The applicant, for the above-mentioned shortcoming of prior art, carries out studying and improving, and provide a kind of multi-stage pressure regulating room arrangement of power station, it is rational in infrastructure, effectively improves the hydraulic connection efficiency between surge-chamber, strengthens overall hydraulic action.
In order to solve the problem, the utility model adopts following scheme:
A kind of multi-stage pressure regulating room arrangement of power station, comprise the overall multiple sub-surge-chamber in being staggeredly arranged up and down, the sub-surge-chamber be positioned at bottom is connected with diversion tunnel, be communicated with by vestibule between adjacent two sub-surge-chambers, described vestibule comprises the main vestibule being communicated with adjacent two sub-surge-chambers and the auxiliary vestibule being communicated with neighbouring two main vestibules, with the first valve on described auxiliary vestibule; Be connected with equalizing main between described sub-surge-chamber, described equalizing main be provided with the second valve.
Further improvement as technique scheme:
To align up and down between two adjacent sub-surge-chambers, staggering between two adjacent sub-surge-chambers is up and down connected to equalizing main.
Technique effect of the present utility model is:
Common high side wall surge-chamber is changed into the multilevel hierarchy of multiple low abutment wall surge-chamber by the utility model, arranges rational vestibule and equilibrium pressure structure, effectively improves the hydraulic connection efficiency between surge-chamber, strengthens overall hydraulic action.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, diversion tunnel; 2, sub-surge-chamber; 3, main vestibule; 4, auxiliary vestibule; 5, the first valve; 6, equalizing main; 7, the second valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Figure 1, the multi-stage pressure regulating room arrangement in the power station of the present embodiment, comprise the overall multiple sub-surge-chamber 2 in being staggeredly arranged up and down, the sub-surge-chamber 2 be positioned at bottom is connected with diversion tunnel 1, be communicated with by vestibule between adjacent two sub-surge-chambers 2, vestibule comprises the main vestibule 3 being communicated with adjacent two sub-surge-chambers 2 and the auxiliary vestibule 4 being communicated with neighbouring two main vestibules 3, with the first valve 5 on auxiliary vestibule 4, the setting of auxiliary vestibule 4, be beneficial to the hydraulic connection efficiency improved between adjacent sub-surge-chamber 2, prevent there is the delayed phenomenon of hydraulic connection due to increasing of surge-chamber, be connected with equalizing main 6 between sub-surge-chamber 2, equalizing main 6 be provided with the second valve 7, equalizing main 6, for balancing the pressure between sub-surge-chamber 2, keeps the pressure balance of rectification surge-chamber, avoids the hydraulic connection between sub-surge-chamber 2 delayed equally.
As shown in Figure 1, the arrangement of equalizing main 6 is: to align up and down between two adjacent sub-surge-chambers 2, staggering between two adjacent sub-surge-chambers 2 is up and down connected to equalizing main 6.
In the utility model, adopt multistage sub-surge-chamber to substitute traditional high side wall surge-chamber, the height of the abutment wall of sub-surge-chamber can be arranged with minimum altitude according to country rock, thus substantially increases the stability of surge-chamber; Auxiliary vestibule and equalizing main are set, avoid the hydraulic connection between multiple sub-surge-chamber delayed, thus improve hydraulic connection efficiency.
Above illustrated embodiment is better embodiment of the present utility model, only be used for conveniently the utility model being described, not any pro forma restriction is done to the utility model, have in any art and usually know the knowledgeable, if do not depart from the utility model carry in the scope of technical characteristic, utilize the utility model disclose the Equivalent embodiments changed or modify in the done local of technology contents, and do not depart from technical characteristic content of the present utility model, all still belong in the scope of the utility model technical characteristic.
