At least one floating pipe 20 (three floating pipes 20 in this embodiment) is provided on the heat radiation water pipe 32.
Each floating pipe 20 is positioned in the middle seam of the U-shaped radiating water pipe 32, and two ends of each floating pipe 20 are respectively fixed on the radiating water pipe 32 through a strapping 21.
The heat radiation water pipe 32, the three floating pipes 20, and the respective corresponding strapping tapes 21 together form a strapping pipe 30.
The float tube 20 serves to increase the overall buoyancy of the lashing tube 30.
Also arranged in the shaft 10 is a cable 36 for supplying the submersible pump 1, which can be arranged along the submersible pump hanging rope 9, the cable 36 enters the cable shaft 13 through a horizontal communication cable duct 15 which communicates with the shaft 10, and down the cable shaft 13 into a bottom cable duct 33 buried in the bottom plate 27, leading to a shore control room.

By moving the gravity pier 14, the distance between the strapping pipe 30 and the rubber dam bag 26 is adjusted so as not to be too wide, so that the water blocking 29 in front of the dam is ensured to be in the heat dissipation influence range of the heat dissipation water pipe 32 and not to freeze.
The bundling pipe 30 can float along with wind around the water surface and up and down along with the water level 17 of the rubber dam through the water inlet hose 18, the water outlet hose 23 and the elastic rope 25. Which serves to assist in the non-icing of the water in front of the dam 29 in front of the lashing tube 30.
The working principle is as follows:
when the device is installed:
firstly, the submersible pump 1 is started, water at the bottom of the vertical shaft 10 is led into the submersible pump water outlet pipe 3 from the submersible pump water inlet 2 of the submersible pump 1, flows through the heat dissipation water inlet pipe 6 and the water inlet hose 18 of the device, enters the heat dissipation water pipe 32, enters the water inlet hole 24 of the U-shaped turn-back dam pier 28, enters the water outlet pipe 35, flows out from the bottom of the bottom plate 27 to the position of the water outlet valve 16 (manual), and after water flows out, the submersible pump 1 is closed, and the water does not flow back by the check valve 4.
The water flows through the submersible pump 1, the submersible pump water outlet pipe 3, the heat dissipation water inlet pipe 6 and the water inlet hose 18 to enter the heat dissipation water pipe 32, returns to the water outlet hose 23 through U-shaped return, and enters the water outlet pipe 35 to form a starting waterway.
At this time, the water level (rubber dam water level 17) in the vertical shaft 10 is always higher than the water level at the position of the water outlet valve 16, water enters from the bottom of the water inlet pipe 5 instead to form inverted siphon, enters the heat dissipation water inlet pipe 6 and the water inlet hose 18 into the heat dissipation water pipe 32, returns to the water outlet hose 23 through U-shaped return, and enters the water outlet pipe 35.
The water flows outwards all the time from the water outlet valve 16 opened at the bottom of the bottom plate 27, and the higher temperature water sucked from the bottom of the shaft 10 in the radiating water pipe 32 plays a role in melting ice and preventing freezing on the colder water surface.
The water flows into the heat dissipation water pipe 32 through the water inlet pipe 5, the heat dissipation water inlet pipe 6 and the water inlet hose 18, returns to the water outlet hose 23 through U-shaped turn-back, and enters the water outlet pipe 35 to flow to the downstream of the rubber dam from the water outlet pipe 35 buried in the bottom plate 27 and the steep slope section 31 of the stilling pool, so as to form an ice water melting inverted siphon waterway.
When not in use, the water outlet valve 16 is closed, the submersible pump 1 is started again when the device is used next time, then the submersible pump 1 is closed, and the inverted siphon work is started again.
The device can be arranged in two dams 28 at two sides of a rubber dam 26, two U-shaped radiating water pipes 32 arranged in parallel horizontally respectively occupy half of the width of the water surface of the water in front of the dam, and the water with higher temperature in the bottom of a vertical shaft 10 in winter in the two dams 28 is absorbed to the water surface (ice surface) of the water in front of the dam 29 with lower temperature.
When the submersible pump 1 is started, part of water flows out from the water inlet below the water inlet pipe 5, and the water supply of the radiating water pipe 32 above the radiating water inlet pipe 6 is not influenced.
When the rubber dam 28 is concreted, a vertical shaft 10, a water inlet hole 24, a cable well 13 and a connecting cable trench 15 are reserved at the front edge position, and the cable well 13 is communicated with a bottom cable trench 33 reserved in the bottom plate 27. The position of the water outlet pipe 35 is reserved at the bottom of the bottom plate 27 and the steep slope section 31 of the stilling pool.
