Abstract
An ice melting device is composed of a submerged pump, a check valve and a main water pipe. The submerged pump is connected with the main water pipe, and the check valve is arranged between the submerged pump and the main water pipe. The two ends of the main water pipe are closed and arranged below the water surface. A water spray nozzle is formed in the main water pipe. An included angle of 45 degrees is formed between the water spray nozzle and the water surface. The submerged pump comprises an operating submerged pump and a standby submerged pump. The ice melting device is remarkable in de-icing effect and stable and reliable in operation and solves the problems that acting force of the ice layer may cause damages to hydraulic structures and hydraulic gates, such as tearing a waterstop of a dam panel, fracturing an arc door hinge supporting base, tearing arc door and gate water seals and making the concrete surfaces crushable to fall off and reducing strength. Column bases of a canal system building even can be pulled up due to frost heaving, the operating stability of gates and hydraulic structure is greatly improved, unsafe accidents caused by manual ice smashing with a steel chisel in winder before are eliminated, and more importantly, the personal safety of workers is protected.
Description
Technical field
The utility model relates to hydraulic engineering field, is a kind of deicing device specifically.
Background technology
In cold district, winter, the waters such as river, reservoir, lake and open dug reservoir, conveyance canal etc. had icing, freeze-up, the process of thawing in various degree, and ice layer thickness is not from 0.3～1.5m etc.Between freeze-up, frost free period, hydraulic structure is because being damaged by quiet ice pressure or dynamic ice pressure effect, and particularly reservoir, large-scale reservoir engineering are even more serious.
Moisture is mainly supplemented by the moisture of concrete floor lower floor, after invasion concrete, form ice crystal, make volume expansion, be subject to horizontal direction extruding or thrust to produce horizontal movement, force structure to change, thereby cause precast concrete or cast-in-situ concrete panel. after frost heave along shrinkage joint, settlement joint dislocation, even cause local fracture, perk, thereby reduced structural strength, shortened engineering application life.
The active force of ice sheet may work the mischief to hydraulic structure and hydraulic gate, as tears dam face slab sealing, pressure break arc door hinge bearing, tears arc door and Jeakage through Sluice Sealant etc.Because its concrete revetment is directly cast on the soil layer of former slope often, thereby cause its bank protection usually to occur level and horizontal frost heave crack, and earth dam upstream slope-protection Chang Yin pull out or ice pushes away and destroys; The upstream face SEA LEVEL VARIATION district on concrete dam is often because freeze thawing destroys, and shows as that loosely peel off on concrete surface, strength decreased; The base for post of canal structure even can be pulled up by frost heave, as repaired not in time, can affect the safe operation of building.
Summary of the invention
In sum, the purpose of this utility model is to provide a kind of deicing device, to guarantee the application life of water engineering facility.
The purpose of this utility model realizes by following technology:
A deicing device, is comprised of submersible pump, non retern valve and water main, and submersible pump connects water main, is provided with non retern valve therebetween; Water main closed at both ends, is placed in water surface below; On water main, have water jet; Water jet and the water surface are 45 ° of angles.
Above-mentioned submersible pump comprises operation submersible pump and standby submersible pump.
Advantage of the present utility model and beneficial effect:
The reaction force principle of the moving water of the utility model utilization, changing water jet into oblique 45 ° of directions sprays, the current of water jet ejection are mapped to concrete surface and can rebound, between the concrete wall of both sides, region forms a natural circulation, reach the effect of disturbance, so just effectively stop near the icing problem of water surface reservoir strobe, guaranteed the application life of water engineering facility.
The utility model is through the operation test in a winter, this cover Ice Breaking System open ice successful, stable and reliable operation, the active force that has solved ice sheet may work the mischief to hydraulic structure and hydraulic gate, as tear dam face slab sealing, pressure break arc door hinge bearing, tear arc door and Jeakage through Sluice Sealant, loosely peel off on concrete surface, strength decreased; The base for post of canal structure even can be pulled up by frost heave etc.; greatly improved the stability of gate and hydraulic structure operation; eliminated former winter by manually pounding the generation of the dangerous accident of ice with drill rod, the more important thing is the personal safety of having played protection staff.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-operation submersible pump, the standby submersible pump of 2-, 3-non retern valve, 4-water main, 5-water jet are put, the 6-water surface.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, a kind of deicing device, is comprised of submersible pump, non retern valve 3 and water main 4, and submersible pump connects water main 4, is provided with non retern valve 3 therebetween; Water main 4 closed at both ends, are placed in the water surface 6 belows; On water main 4, have water jet 5; Water jet 5 is 45 ° of angles with the water surface 6.
Submersible pump comprises operation submersible pump 1 and standby submersible pump 2.
Embodiment
Submersible pump ice-melt is placed on to reservoir strobe and needs near the water surface water conservancy project equipment of ice-melt 6 times, the top of water main 4 has 2 row's water jets 5.
After freezed in winter, open operation submersible pump 1, operation submersible pump 1 is by the warm water suction water main 4 of reservoir bottom, and water flows out via the water jet 5 of water main 4 again, and water and ice sheet that water jet 5 flows out are 45° angle, through after a while, ice sheet are melted.
If when operation submersible pump 1 cannot use, can open standby submersible pump 2, complete above-mentioned ice-melt work.
Claims (2)
1. a deicing device, is comprised of submersible pump, non retern valve (3) and water main (4), it is characterized in that: described submersible pump connects water main (4), is provided with non retern valve (3) therebetween; Described water main (4) closed at both ends, is placed in the water surface (6) below; On water main (4), have water jet (5); Water jet (5) is 45 ° of angles with the water surface (6).
