The applicant, for the above-mentioned shortcoming of prior art, carries out studying and improving, and provides a kind of short protection-apron type power station absorption basin structure, and it substantially reduces protection-apron length, is adapted to the use of various region, has low, the convenient feature of arranging of cost.
In order to solve the problem, the utility model adopts following scheme:
A kind of short protection-apron type power station absorption basin structure, comprise the absorption basin being arranged at outlet structure escape works downstream, absorption basin is with energy dissipating tooth bank and the slow water section and the energy dissipating tail bank that are positioned at energy dissipating tooth bank both sides, slow water section is connected with outlet structure escape works, the top of energy dissipating tooth bank is provided with slow water cover, slow water cover is installed on absorption basin by many root posts, delays with diversion space between water cover and energy dissipating tooth bank, and the two ends of slow water cover are stretched out downwards to the both sides of energy dissipating tooth bank; The side that meets water of energy dissipating tooth bank is with the slow groove that meets water, and its land side delays groove with itself and backwater, and meet water slow groove and slow water section seamlessly transit, and backwater delays groove and seamlessly transits the groove that meets water to energy dissipating tail bank.
Further improvement as technique scheme:
Described slow water cover is arcuate structure, and its two ends are respectively to lower bending, and the arc-shaped concave at two ends delays groove towards meet water slow groove and backwater, slow water cover and meet water between slow groove and form the diversion space that raises up that meets water, and backwater delays between groove and forms backwater sinking diversion space.
The slow groove that meets water of described energy dissipating tooth bank tilts to slow water section.
Described energy dissipating tail bank rolls to downstream and tiltedly arranges.
Technique effect of the present utility model is:
The structure that the utility model adopts energy dissipating tooth bank to match with slow water cover, realize repeatedly concentrating energy dissipating, effect of energy dissipation is good; Its compact conformation, without the need to building longer protection-apron, reduces construction cost, not by the restriction in narrow place, and wide accommodation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, outlet structure escape works; 2, absorption basin; 21, slow water section; 22, energy dissipating tail bank; 221, meet water groove; 23, energy dissipating tooth bank; 231, meet water slow groove; 232, backwater delays groove; 3, slow water cover; 4, diversion space; 5, column; 6, meet water the diversion space that raises up; 7, backwater sinking diversion space.
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 short protection-apron type power station absorption basin structure of the present embodiment, comprise the absorption basin 2 being arranged at outlet structure escape works 1 downstream, absorption basin 2 is with energy dissipating tooth bank 23 and the slow water section 21 and the energy dissipating tail bank 22 that are positioned at energy dissipating tooth bank 23 both sides, slow water section 21 is connected with outlet structure escape works 1, the top of energy dissipating tooth bank 23 is provided with slow water cover 3, slow water cover 3 is installed on absorption basin 2 by many root posts 5, delay with diversion space 4 between water cover 3 and energy dissipating tooth bank 23, the two ends of slow water cover 3 are stretched out downwards to the both sides of energy dissipating tooth bank 23; The side that meets water of energy dissipating tooth bank 23 is with the slow groove 231 that meets water, and its land side delays groove 232 with itself and backwater, and the slow groove 231 that meets water seamlessly transits with slow water section 21, and backwater delays groove 232 and seamlessly transits the groove 221 that meets water to energy dissipating tail bank 22.
Slow water cover 3 is arcuate structure, its two ends are respectively to lower bending, the arc-shaped concave at two ends delays groove 232 towards meet water slow groove 231 and backwater, slow water cover 3 and meet water between slow groove 231 and form the diversion space 6 that raises up that meets water, and backwater delays between groove 232 and forms backwater sinking diversion space 7.
