Description
Technical Field
The utility model relates to the technical field of water conservancy and hydropower engineering, in particular to a mobile pump ship for lowering ecological water.
Background
The water resource provides important support for the development of human society, and in order to improve the utilization rate of the water resource, the water retaining dam is usually built in a natural river to store the water resource, so that the water resource is convenient for human production and living use.
In the construction engineering of the barrage, a temporary cofferdam is firstly constructed at the upstream and downstream of the barrage to ensure that the barrage is constructed in a dry environment, and meanwhile, in order to ensure that the downstream river of the barrage is not broken, a diversion facility is required to be constructed between the upstream and downstream of the cofferdam to guide the water flow in the upstream river to the downstream, so that the ecological water flow is ensured; when the barrage is built and has water storage capacity, the barrage is required to store water, in order not to influence the existence of downstream ecological species, the barrage is set as a downstream water drainage facility, the water flow of the water drainage facility is extremely small, the influence on water storage is small, because the water drainage facility is generally much higher than the diversion facility, after the barrage is blocked by the diversion facility, the water level of the barrage does not reach the water drainage facility elevation, namely, the water level is in the elevation section of the diversion facility and the water drainage facility, at this time, the water drainage facility in the barrage cannot drain water to the downstream river, the downstream ecological water flow is cut off, and because the barrage with medium and large scale can last for a plurality of months or longer in the water storage period, the living environment of downstream residents and organisms of the barrage is seriously influenced.
In order to solve the problem of ecological water flow at the downstream of the barrage, people generally adopt temporary modes of water pump pressurizing from upstream to downstream to lift water or siphon pipe and the like, because the ecological water flow required by the barrage of medium and large scale is larger, the elevation from a diversion facility to a drainage facility is higher, the water pump is fixed at the river bank, the theoretical suction range of the water pump is 10m, and the water pump pressurizing water lifting is adopted, so that a certain difficulty is brought to specific implementation; when siphon measures are adopted, and water is stored in the initial stage of upstream, the siphon is also required to be arranged to be large because the height difference between the upstream water level and the downstream water level is not large and the ecological water flow is required to be large, so that the implementation is difficult.
Disclosure of Invention
The utility model aims to provide a mobile pump ship for lowering ecological water, which is used for solving the problem that when the water level is in the elevation section from a diversion facility to a water discharge facility, water is difficult to drain from upstream to downstream.
In order to solve the problems, the technical scheme is as follows:
the utility model provides a mobile pump ship of ecological water of transferring, includes the pump ship body, the pump ship body is by the hollow pole level that a plurality of both ends all are in sealing state fixedly concatenation side by side forms, fixedly installs the water pump unit on the pump ship body, and water pump unit top activity intercommunication has the rocking arm pipe, and the fixed pipe one end of rocking arm pipe other end activity intercommunication, fixed pipe other end intercommunication connecting pipe, connecting pipe intercommunication ecological drain pipe.
The basic principle of the technical scheme is as follows: the fixed pipe is fixedly arranged on the appropriate upstream river bank side, the pump boat body is placed in an upstream river channel, the pump boat body and the water pump unit can float on the upstream water surface under the traction of the rocker pipe, the water pump unit is started, the water pump unit pumps water in the upstream into the fixed pipe through the rocker pipe, the water in the fixed pipe flows into the ecological water drain pipe through the connecting pipe, finally flows out of the ecological water drain pipe and enters a downstream river channel, and the ecological water flow of the downstream river channel is guaranteed not to be cut off.
The beneficial effect of this scheme lies in:
1. compared with the existing mode of directly adopting a water pump to pump water from upstream to downstream, the scheme adopts the combination of the water pump unit and the pump ship body, and because the pump ship body is formed by splicing hollow rod water, the pump ship body can bear the water pump unit to float on the surface of upstream river water, and can rise along with the rising of the upstream water level, so that the water pump unit borne on the pump ship body always floats on the water surface along with the pump ship body, the water pump unit floating on the water surface can easily pump the upstream water into the rocker arm pipe by only needing very small pressure, and then flows through the fixed pipe, the connecting pipe and the ecological water discharge pipe, and finally flows into a downstream river channel.
2. After the upstream water level of the barrage reaches the elevation of a water drainage facility and ecological water flow can be normally drained, the rocker arm pipe is pulled to take out the pump boat body in the upstream river together with the water pump unit from the upstream river, and then the pump boat body and the water pump unit are recycled on different hydraulic engineering projects.
Further, the water pump unit comprises a water pump, the water pump extends from the inlet end of the water pump to the position below the pump ship body, the outlet end of the water pump is movably communicated with the rocker arm pipe through the universal spherical joint, and the outlet end of the water pump is provided with a flow regulating valve. The flow regulating valve can control the water lifting flow of the water pump, so that the hydraulic loss of the outlet of the water pump is avoided from being increased excessively when the lift is low, and the normal operation of the water pump is influenced.
Further, a water pump variable frequency control cabinet positioned at one side of the water pump unit is fixedly arranged on the pump ship body, and the water pump variable frequency control cabinet is electrically connected with the water pump unit. The water pump variable frequency control cabinet reduces the running rotation speed of the water pump by reducing the frequency of the power end, and properly widens the running range of the water pump.
Further, the other end of the rocker arm pipe is movably communicated with one end of the fixed pipe through a universal spherical joint. In the process that the pump ship body rises along with the water level, the universal spherical joint can enable the rocker arm pipe to deflect freely so as to adjust to a proper angle.
Further, the fixed pipe is a cross-shaped joint, the left end and the right end of the joint are respectively communicated with the rocker pipe and the connecting pipe, the upper end of the joint is in a sealing state, and the upper end of the joint is fixedly connected with the mounting seat. The installation seat is fixedly arranged on the river bank side, and the joint can be fixedly arranged on the river bank side.
Further, an ecological drain gate is arranged at the end of the ecological drain pipe. The ecological water drain gate controls the opening and closing of the ecological water drain pipe.
