Description

Technical Field

[0001] This utility model belongs to the field of underwater concrete structure curing and antifreeze technology, specifically relating to an underwater concrete structure antifreeze curing device. Background Technology

[0002] Underwater concrete structures are widely used in engineering construction, such as lock piers and walls, and pile foundations for bridges and wharves. Compared with land-based concrete structures, underwater concrete structures face more complex environmental conditions. They are constantly submerged in water and are subject to the combined effects of various factors, including water erosion, sediment abrasion, ion corrosion, and temperature variations.

[0003] In the Jianghuai region, although the average winter temperature is higher than in northern regions, the water temperature sometimes approaches zero degrees Celsius at night, making the water surface prone to short-term freezing. Existing concrete structures in this region were not designed with freeze-thaw resistance in mind, making them susceptible to the stress of short-term freezing. This can lead to reduced strength, decreased durability, and even cracks and spalling, severely impacting the safety and service life of the structures.

[0004] Current underwater concrete curing technologies primarily focus on performance protection against ion erosion, structural carbonation, and silt erosion, but they do not adequately consider the antifreeze function of concrete structures. In view of these issues, there is an urgent need to develop a device specifically designed for antifreeze curing of underwater concrete structures in the Jianghuai region. This device would effectively protect existing concrete structures in the Jianghuai region from freezing damage in underwater environments, thereby extending their service life and ensuring the safety and reliability of engineering projects.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1 like Figures 1 to 5 As shown, an underwater concrete structure antifreeze curing device includes: N sets of tracks, each track having a slidable disturbance device. Furthermore, the length of the tracks is determined according to requirements, and they are installed on a carrier by anchoring with rebar. The carrier can be a planar carrier such as a pier wall, or a cylindrical carrier such as a pile foundation. Specifically, during installation, the height requirements for the tracks are as follows: the top end should be 1.0 meter or more above the highest water level, and the bottom end should not be lower than 0.5 meters below the lowest water level.

[0022] To prevent the water near the device from refreezing during disturbances, each track in this embodiment has a heating function. This is achieved as follows: the track is a steel internal toothed structure with a triangular outer cross-section; a heating resistance wire is placed inside the track. Correspondingly, the heating resistance wire is connected to the power module via a cable.

[0023] Correspondingly, the disturbance device includes a displacement device mounted on the track, wherein the displacement device has a reciprocating degree of freedom along the length of the track. In other words, when there is no need to disturb the water, the displacement device is located above the track; when it is necessary to disturb the water, the displacement device moves downwards to approach the water, facilitating contact with and disturbance of the water to prevent freezing.

[0024] Therefore, the displacement device is equipped with a water disturbance mechanism. In order to control whether it needs to move and the distance it should move downward according to the temperature, a temperature sensor and a water level sensor are installed at the top and bottom of the displacement device, respectively.

[0025] Furthermore, the water disturbance mechanism described in this embodiment includes: an eccentric motor fixed to the displacement device, and a disturbance head mounted on the output shaft of the eccentric motor. The disturbance head has a connecting end and a disturbance end. Further, the connecting end is a steel cylinder with a diameter of 4 cm. The disturbance end is a steel sphere with a diameter of 5 cm. The steel cylinder and the steel sphere can be fixedly connected by welding.

[0026] The eccentric motor is connected to the disturbance head. During operation, it drives the disturbance head to stir the water surface through irregular rotation. By using the principle of water surface disturbance, it prevents the water from freezing near the structure, thus protecting the structure from freeze-thaw damage that affects its durability and achieving the effect of increasing water disturbance.

[0027] To fit the track, the top of the displacement device is a cubic structure, and a movable frame is connected to the cubic structure. The movable frame has a concave triangular cross-section to fit the track; a motor is installed inside the movable frame, and the output shaft of the motor is connected to a gear, which meshes with the steel internal gear structure.

[0028] The above structure enables the control device to move vertically up and down. When the temperature sensor detects that the current ambient temperature is below a threshold, the power module is triggered, and the displacement device moves downward. The threshold value is set according to the environment, such as 2℃.

[0029] Furthermore, the bottom of the displacement device has a triangular pyramidal structure, meaning that the lower pointed structure can scrape off plants and animals attached to the track, ensuring the safe movement of the device.

[0030] It is worth mentioning that the displacement device and water disturbance mechanism are also connected to the power module via cables. For resource utilization, the power module is at least a solar power generation module. In other words, the power module is also connected to other power generation modules. This embodiment prioritizes solar power generation modules for environmental protection and energy conservation. Other types of power generation modules will be selected in adverse weather conditions. The solar panels are installed on the top surface of the carrier and can be used to generate and store energy during the day, ensuring the normal operation of the structure.

[0031] In practical applications, such as when installed on a planar surface, the tracks should be arranged laterally at specified intervals. For example, when the structure is a planar structure such as a pier or buttress, the tracks should be arranged laterally at certain intervals, with a suitable interval of 3-5 meters, and at least 5 sets of disturbance devices should be installed.

[0032] Alternatively, when installed on a cylindrical carrier, the tracks can be arranged in a circumferential pattern at specified intervals. For example, when the structure is a cylindrical structure such as a pile foundation, four sets of tracks can be evenly arranged circumferentially according to their cross-sectional diameter.

[0033] For both of the above application scenarios, after installation, cables are used to connect each disturbance device and track to the solar panel in sequence.

[0034] In use, the internal sensors of the disturbance device automatically control the operation: when the air temperature is at or below the minimum threshold, the disturbance device connects to the power control unit and begins to work. The displacement device moves vertically from top to bottom until the water level sensor at the bottom contacts the water surface and stops moving. At the same time, the eccentric motor and the heating resistance wire of the track start to work. The eccentric motor drives the disturbance head to stir the water surface through irregular rotation, preventing the water from freezing near the structure through the principle of water surface disturbance. At the same time, the track is heated to warm the water near the structure, preventing the water surface near the structure from freezing.

[0035] When the temperature rises above the maximum threshold, the eccentric motor and the track heating resistance wire stop working, the displacement device climbs up to the top of the track and then the power is cut off, and it stops working.
