In carrying vehicle top；Carrying vehicle has universal wheel；Hoist engine is located at dam top, and hoist engine passes through drag rope and carrying vehicle
It is connected；Controller is connected with water pump, hoist engine respectively by cable.
Hoist engine is fixed on dam top, and carrying vehicle is longitudinally disposed along dam.
Carrying vehicle lower end is provided with liquid level sensor, and liquid level sensor is connected by cable with controller.
Limiting and protecting device is provided between hoist engine and carrying vehicle, limiting and protecting device is connected by cable with controller.
Operation principle of the present utility model：
The present apparatus is according to the mass-and heat-transfer mechanism in Thermal power engneering, the big calorimetric cleverly stored using reservoir area water
Can, the water surface builds a piece of not ice field near dam, fundamentally solves the problems, such as the freeze injury of dam.
Freezeup period in the winter time, controller is according to the data of liquid level sensor real-time Transmission, by controlling the rotation of hoist engine,
Folding and unfolding drag rope, carrying vehicle operating position is determined, carrying vehicle is in precalculated position, mozzle spray all the time in the course of the work
Mouth remain at at the water surface of dam contact position.
Controller control water pump is opened, and water pump extracts the water of reservoir area depths, is pumped to and dam contact position by mozzle
The water surface, form the running water that flows all the time in mozzle nozzle, and because the water temperature of winter reservoir area depths is higher than surface temperature,
Therefore depths water pump delivers to water surface release heat energy, prevents the water surface from freezing, realizes the antifreeze purpose of dam.Controller passes according to liquid level
The data of sensor real-time Transmission, with reference to the position of the factors, in real time adjustment carrying vehicle such as climate temperature, water level height and field condition
Put.
Hoist engine is fixed on dam top, and carrying vehicle is longitudinally disposed along dam.And universal wheel is arranged below in carrying vehicle, so
Hoist engine can draw carrying vehicle and be vertically moved along dam, ensure that the water surface and dam contact position can obtain antifreeze processing.
Limiting and protecting device is used to protect hoist engine when liquid level sensor fails, and avoids generation capstan winch from excessively tightening up and kills
Problem.
The beneficial effects of the utility model：
This covering device is to solving the problems, such as that dam freezing prevention has technical feasibility and economic serviceability, to solve power station
Reservoir area dam face slab freeze injury problem have found new method, there is provided new technology, to solving the current country in severe cold area construction
The similar dam face slab freeze injury problem that power station runs into has highly important directive significance.The present apparatus is simple in construction, operable
Property is strong, and the problem automatically adjusted can not be realized by solving severe cold area dam defroster, automatically control it is achievable it is unmanned from
And make the popularization of device that there is huge advantage.

Embodiment
Refer to shown in Fig. 1, Fig. 2：
The device includes water pump 1, mozzle 2, carrying vehicle 3, hoist engine 4 and controller 5, wherein water pump 1 and mozzle 2
It is arranged on carrying vehicle 3, pump intake 6 is located at the bottom of carrying vehicle 3, and pump outlet 7 is connected with the lower port of mozzle 2,
Mozzle spout 8 is located at the top of carrying vehicle 3；Universal wheel 9 is arranged below in carrying vehicle 3；Hoist engine 4 is located at dam top, hoist engine
4 are connected by drag rope 10 with carrying vehicle 3；Controller 5 is connected with water pump 1, hoist engine 4 respectively by cable 11.
Hoist engine 4 is fixed on dam top, and carrying vehicle 3 is longitudinally disposed along dam.
The lower end of carrying vehicle 3 is provided with liquid level sensor 12, and liquid level sensor 12 is connected by cable 11 with controller 5.
Limiting and protecting device 13 is provided between hoist engine 4 and carrying vehicle 3, limiting and protecting device 13 passes through cable 11 and control
Device 5 processed is connected.
Operation principle of the present utility model：
The present apparatus is according to the mass-and heat-transfer mechanism in Thermal power engneering, the big calorimetric cleverly stored using reservoir area water
Can, the water surface builds a piece of not ice field near dam, fundamentally solves the problems, such as the freeze injury of dam.
Freezeup period in the winter time, controller 5 is according to the data of the real-time Transmission of liquid level sensor 12, with reference to climate temperature, water level
The factor such as height and field condition, determines the operating position of carrying vehicle 3, by controlling the rotation of hoist engine 4, folding and unfolding pull rope
Rope 10, carrying vehicle 3 is reached precalculated position in the course of the work, keep mozzle spout 8 all the time in the water with dam contact position
At face.
Controller 5 controls water pump 1 to open, and water pump 1 extracts the water of reservoir area depths, is pumped to by mozzle 2 and is connect with dam
The water surface of synapsis, the running water flowed all the time is formed at mozzle spout 8, and because the water temperature of winter reservoir area depths is higher than top layer
Water temperature, therefore depths water pump delivers to water surface release heat energy, prevents the water surface from freezing, realizes the antifreeze purpose of dam.The basis of controller 5
The data of the real-time Transmission of liquid level sensor 12, with reference to factors such as climate temperature, water level height and field conditions, adjustment in real time is held
The position of carrier vehicle 3.
Hoist engine 4 is fixed on dam top, and carrying vehicle 3 is longitudinally disposed along dam.And universal wheel 9 is arranged below in carrying vehicle 3,
So hoist engine 4 can draw carrying vehicle 3 and be vertically moved along dam, ensure that the water surface and dam contact position can obtain antifreeze place
Reason.
