At present, the Chinese patent with publication number 212058902 discloses an ecological flow monitoring device for a small hydropower station, which is mainly characterized in that the ecological flow monitoring device is provided, but the application is a small hydropower station ecological flow reconstruction device, and the two types of devices, the adopted materials and the purposes are different; the chinese patent publication No. 212336161 discloses an automatic water intake device with ecological flow, which is different from the application object of the present application and has a different installation structure type.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems, the utility model provides an automatic ecological flow discharge and transformation device for a small hydropower station, which aims at some small hydropower stations or small-scale reservoirs built in early days, does not have a conventional ecological water taking structure due to the limitation of concept, structure and terrain, forms a new ecological flow discharge device by carrying out secondary transformation on the water taking structure of the small hydropower stations built in early days, and solves the problem of regular ecological water supply in the downstream.
The utility model is realized by the following technical scheme.
The utility model provides an automatic release transformation device for ecological flow of a small hydropower station, which comprises a groove formed in the side wall of a built small hydropower station approach channel; a water passing groove is formed, and a metal flap valve is arranged at the tail part of the water passing groove; rubber pads are arranged on the periphery of the metal flap valve, and the upper part and the lower part of the metal flap valve are respectively anchored with an upper anchor and a lower anchor; one side of the metal flap valve is provided with a protective maintenance platform, and one end of the protective maintenance platform is connected with a pedestrian ladder.
The cross section of the water passing groove is circular.
The protection maintenance platform is made of stainless steel.
The metal flap valve is tightly connected with the rubber pad.
The pedestrian ladder is made of stainless steel.
The utility model has the beneficial effects that: the ecological water demand of the downstream of the small hydropower station can be effectively ensured, the structure is simple, the required materials are common, the construction and the installation are convenient, and meanwhile, the problem that the ecological flow device is not arranged in the early small hydropower station can be solved without the control of related management personnel; the problem that the early-built small hydropower station is not provided with an ecological flow device can be solved, the purpose of low-stream ecological water demand is easily realized, and the green hydropower concept advocated at present is met.

Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
Example 1
As shown in fig. 1 to 3, an automatic release modification device for ecological flow of a small hydropower station comprises a groove formed in the side wall 7 of an established small hydropower station approach channel; a water passing groove is formed, and a metal flap valve 1 is arranged at the tail part (namely the backwater side of the approach channel) of the water passing groove; the periphery of the metal flap door 1 is provided with a rubber pad 2, and the upper part and the lower part of the metal flap door 1 are respectively provided with an upper anchor 3 and a lower anchor 4; one side of the metal flap door 1 is provided with a protection maintenance platform 5, and one end of the protection maintenance platform 5 is connected with a pedestrian ladder 6.
Example 2
The protocol of example 1 was followed and: the cross section of the water passing groove is circular.
Example 3
The protocol of example 1 was followed and: the protection maintenance platform 5 is made of stainless steel.
Example 4
The protocol of example 1 was followed and: the metal flap valve 1 is tightly connected with the rubber pad 2 to play a role in buffering.
Example 5
The protocol of example 1 was followed and: the pedestrian ladder 6 is made of stainless steel.
Example 6
Based on the above embodiment, specifically:
when the approach channel is flooded, under the action of the pressure of the approach channel water, the metal flap valve can realize the adjustment of the opening degree, thereby realizing the purpose of lowering different ecological flows and meeting the requirements of different ecological discharge amounts of the small hydropower station in the dry period and the flood period specified by the specification; meanwhile, the protective maintenance platform is arranged on the lower side of the metal flap valve, and can enter the protective maintenance platform through the side pedestrian ladder, so that workers can conveniently and regularly maintain the metal flap valve.
From above, this device novel structure is unique, the construction is convenient, and stability is good, structurally reforms transform at the original approach canal of little power station, forms ecological flow bleeder mechanism, satisfies the requirement of the little power station low reaches ecological water demand of building in early stage, does not need relevant managers to carry out the management and control simultaneously, has stronger use value, better social and economic benefits.
In conclusion, the utility model forms a new water passing channel by performing secondary grooving on the side wall of the original approach channel on the bank of the small hydropower station, and then a metal flap valve is arranged at the tail part of the channel, namely on the backwater side of the approach channel, so that the small hydropower station which is not provided with the ecological water drainage device in the early stage is transformed to form the ecological flow automatic discharge transformation device.
