Description

Technical Field

[0001] The invention relates to the technical field of concrete maintenance, in particular to a circulating water device for large-volume concrete cracks in a reservoir dam. Background Art

[0002] During the pouring of large-volume concrete of reservoir dams, a large amount of heat will be generated inside the concrete due to the hydration reaction of cement, causing the temperature to rise rapidly. However, the thermal conductivity of concrete is poor, and it is difficult to dissipate this heat quickly, resulting in a significant difference between the internal temperature of the concrete and the surface temperature, which in turn generates temperature stress. When the temperature stress exceeds the tensile strength of the concrete, cracks will be generated, seriously affecting the overall strength and stability of the concrete. In order to avoid the generation of concrete cracks, it is usually adopted to pre-buried pipes inside the concrete so that cooling water passes through the pipes and then exchanges heat with the concrete, thereby reducing the generation of cracks. At present, in the process of water circulation cooling of large-volume concrete of reservoir dams, water is usually taken from the surrounding rivers. Since the extracted water is often accompanied by certain impurities, these impurities often enter the pre-buried pipes inside the concrete during subsequent use. In severe cases, the pipes will be blocked, thereby adversely affecting the cooling of the concrete. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention enables personnel to switch the pumping paths between the water pump and the pumping pipe and between the water pump and the cooling water tank during the concrete pouring and cooling operation of the reservoir dam through the arrangement of the output pipe, the input pipe, the cooling water tank, the driving motor, the adjusting screw, the movable baffle, the adjusting baffle frame, the circulating pipe, the water pump, the tee pipe, the guide box, the filter cartridge, the pumping pipe and the filter plate, so as to facilitate personnel to carry out water drawing operation from the river when in use, and effectively filter the impurities in the cooling water when drawing water, so as to avoid the impurities from entering the interior of the embedded pipe and causing blockage, thereby ensuring that the cooling operation can be carried out stably, and the cooling water collected in the cooling water tank can be recycled after the water drawing operation is completed, so as to effectively reduce the waste of water resources.

[0016] 2. The present invention provides a movable rod, a accommodating hole, a first spring, an annular fixed frame, a second spring, a movable disk and a dredging block. In the process of switching the water pumping path of the water pump by moving the movable baffle downward for adjustment, the movable baffle can contact the top of the movable rod and push the movable rod to move downward. The movement of the movable rod can compress the first spring in the accommodating hole, and can drive the annular fixed frame, the second spring, the movable disk and the dredging block to move downward, so that the dredging block can be inserted into the filter holes on the filter plate under the action of the movement, and impurities blocked in the filter holes are pushed downward, thereby achieving the effect of preliminary cleaning of the filter plate and avoiding the filter plate being blocked by impurities and affecting subsequent use. The purpose of limiting the movable disk and the annular fixed frame is achieved by setting the limiting slide rod, avoiding the displacement between the movable disk and the annular fixed frame.

[0017] 3. The present invention provides a cleaning scraper. When the adjusting screw rotates to adjust the water pumping path of the water pump, the adjusting screw can drive the cleaning scraper to rotate, so that the impurities attached to the bottom of the filter plate can be scraped off, thereby further achieving the effect of cleaning the bottom of the filter plate, greatly reducing the probability of the filter plate being blocked, and through the provision of a sewage pipe and a sealing cover, it is convenient for personnel to discharge the impurities cleaned inside the filter cartridge.

[0018] 4. The present invention can limit the position of the movable baffle during the movement and adjustment of the movable baffle through the provision of a limit block and a rubber sealing ring. During the contact between the movable baffle and the limit block, the rubber sealing ring can seal the movable baffle and the adjusting screw to avoid water seepage due to a gap between the adjusting screw and the movable baffle. The provision of the rubber sealing pad effectively improves the sealing effect of the contact between the adjusting baffle frame and the guide box, so that the adjusting baffle frame can better seal the mouths of the tee pipe and the circulation pipe during the movement and adjustment. The provision of the lifting ears and lifting holes facilitates personnel to use lifting equipment to lift and transport the entire unit. The provision of the support rod achieves the purpose of supporting and fixing the output pipeline. BRIEF DESCRIPTION OF THE DRAWINGS
