Description

TECHNICAL FIELD

[0001] The utility model belongs to underwater construction technical field, especially relate to a pipeline immersion cooling device of self -adaptation water level change. BACKGROUND

[0002] The construction project in hot regions such as Africa grows day by day, when carrying out underwater concrete pouring under the local high temperature environment, the mode of pumping concrete by arranging pump pipe on water surface is often used. However, when the environmental temperature exceeds 40 DEG C, the pumping capacity of concrete in the pipeline is severely limited, and the high temperature of concrete also affects the pouring quality.

[0003] Therefore, various cooling measures need to be taken to ensure the pouring quality in construction, including using ice or ice water cooling raw materials, reducing transportation distance and cooling the pumping pipeline. Since the ice-making capacity is weak in some backward areas, the main cooling method still depends on the water temperature of deep water area to reduce the temperature of the pumping pipeline, and the commonly used mode is to use water pump to spray cooling, but this mode can only cool the locally sprayed pipeline, when the atmospheric temperature is too high, the temperature of the sprayed water may also rise due to contact with high temperature air, and the cooling effect of the pump pipe is reduced. Another measure is to immerse the pumping pipeline in water through fixed buoyancy equipment, and use the low temperature of water to reduce the temperature of the pipeline. However, this method has significant problems in areas with large water level changes, since the pipeline is connected to form a rigid structure, and is mainly suspended in the water body by external buoyancy force, if the buoyancy force suddenly increases with the change of water level, the pipeline in water will be arched by the buoyancy force; if the buoyancy force suddenly decreases, the gravity of the pipeline in water is greater than the buoyancy, and the pipe joints will have a sinking trend. This will cause the stress imbalance of the connection between the pipelines, and further cause distortion and leakage, affecting the continuity and pouring quality of concrete pouring.

[0004] At present, the existing pipeline immersion cooling device on the market is directly placed in water to provide fixed buoyancy, cannot be adjusted according to the change of water level, has great influence on the stress of the pipeline, has poor durability, and is prone to problems such as joint loosening and pipe explosion during work.

[0005] The utility model discloses a pipeline immersion cooling device of self -adaptation water level change solves the above -mentioned problems. UTILITY MODEL CONTENTS

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following embodiments or drawings are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0019] An adaptive water level change-adaptive pipe immersion cooling device, such as Figs. 1 to 4 As shown, the system includes a floating base 2, a buoyancy adjustment box 3, and a pressure rod 4. The floating base 2 supports the tunnel 1. There are two buoyancy adjustment boxes 3, which are symmetrically distributed on both sides of the floating base 2. The pressure rod 4 is installed on the upper end of the two buoyancy adjustment boxes 3. A force transmission rod 5 is provided on the floating base 2. The top end of the force transmission rod 5 is connected to the pressure rod 4. An inflation valve 6 and an exhaust solenoid valve 7 are installed on the top of the buoyancy adjustment box 3. An inlet and outlet solenoid valve 8 is installed on the bottom of the buoyancy adjustment box 3. Pressure sensors 9 are installed at the connection points between the two ends of the pressure rod 4 and the two buoyancy adjustment boxes 3.

[0020] Multiple sets of floating bases 2 and buoyancy regulating boxes 3 are arranged along the pipe 1. The floating bases 2 are located at the bottom of the pipe 1 and support the pipe 1 in the water. The buoyancy regulating boxes 3 are located on both sides of the pipe 1 and float in the water. The buoyancy regulating boxes 3 provide buoyancy for the floating bases 2.

[0021] When the water level changes, the buoyancy regulating box 3 rises or sinks accordingly. Since the buoyancy regulating box 3 remains unchanged, the floating base 2 remains in its initial position due to the pipe 1, causing a change in pressure at the connection between the pressure rod 4 and the buoyancy regulating box 3. Therefore, the inflow and outflow of water in the buoyancy regulating box 3 can be controlled by monitoring the pressure sensor 9 connected to both ends of the pressure rod 4. The buoyancy is automatically adjusted according to the rise and fall of the water level, keeping the buoyancy of the pipe 1 relatively stable under water level changes, thereby reducing the impact of external force changes on the pipe 1 and improving the durability and stability of the pipe.

[0022] Pressure sensor 9 is connected to an external control system via a power signal line. The control system is connected to inflation valve 6, exhaust solenoid valve 7, and inlet / outlet solenoid valve 8 via power signal lines. The power signal lines are wrapped with a waterproof membrane.

[0023] Implementation method:

[0024] (A) Device assembly

[0025] Assemble the device according to the structural diagram, and distribute the device on the pipeline at certain intervals according to the pipeline plan.

[0026] (B) Calculate the buoyancy force of the pipe in water

[0027] Calculate the buoyancy force required to keep the pipe suspended in water based on its size and volume.

[0028] (C) Buoyancy adjustment

[0029] The parameter P of the pressure sensor 9 is set according to the size of the buoyancy. When the water level rises, if the monitoring value of the pressure sensor 9 is greater than P, it indicates that the buoyancy becomes larger, and the pipeline 1 has a tendency to move upward, at this time, the control system controls the exhaust electromagnetic valve 7 and the water inlet and outlet electromagnetic valve 8 to exhaust and fill water, so as to reduce the buoyancy to the value P; when the water level drops, if the monitoring value of the pressure sensor 9 is less than P, it indicates that the buoyancy becomes smaller, and the pipeline 1 has a tendency to move downward, at this time, the control system controls the air inlet pump 6 to start air inlet, and the water inlet and outlet electromagnetic valve 8 opens the water outlet, so as to increase the buoyancy to the value P. With the fluctuation of the water level, the buoyancy is intelligently controlled, and the stress balance of the pipeline 1 is maintained.

[0030] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification or equivalent change made according to the technical essence of the present application to the above embodiment falls within the protection scope of the present application.
