Abstract
Description
Technical Field
[0001] This utility model relates to the field of crack repair technology, and in particular to a high-efficiency repair device for microbial repair of concrete cracks. Background Technology
[0002] The high-efficiency microbial repair device for concrete cracks is an engineering equipment developed based on the mineralization function of microorganisms. By precisely controlling the microbial living environment, it activates the metabolic activity of specific functional microorganisms, prompting them to secrete cementing substances such as calcium carbonate, which then directionally fill concrete cracks. Its core application is the active repair of cracks in concrete structures such as buildings, roads, and bridges. It can accelerate the crack closure process, improve the structure's impermeability and mechanical properties, and combines eco-friendliness with long-term repair characteristics, providing a bio-based solution for concrete structure maintenance.
[0003] A search revealed that publication number CN220725103U discloses a repair device for microbial repair of concrete cracks, comprising: a base plate; a support, the support being disposed on the top of the base plate; a material bucket, the material bucket being disposed on the support; a limiting plate, the limiting plate being fixedly installed on the support; multiple limiting rods, the multiple limiting rods being fixedly installed on the bottom of the limiting plate, the multiple limiting rods being fixedly connected to the support; a lifting mechanism, the lifting mechanism being disposed on the top of the base plate; a repair mechanism, the repair mechanism being disposed on one side of the support; and a compression guiding mechanism, the compression guiding mechanism being disposed on the support.
[0004] The prior art describes a repair device for microbial repair of concrete cracks. While it offers advantages such as time-saving and labor-saving operation, ease of repairing cracks at high points on walls, and convenient operation, it only injects repair slurry into the hopper by pressing with a pressure plate without a mixing mechanism. When left to stand or be stored for a long time, the microbial repair slurry is prone to stratification, sedimentation, or uneven composition. This may lead to an imbalance in microbial distribution and reduced activity, affecting the bonding performance of the repair slurry and the crack filling effect, ultimately weakening the repair quality and durability of the concrete cracks.
[0005] Therefore, we propose a highly efficient repair device for microbial repair of concrete cracks. Utility Model Content

[0009] Furthermore, a first rotating shaft is rotatably inserted on the left side of the drive box, and a first gear is fixedly installed on the right end of the first rotating shaft. The first gear meshes with the second gear and the third gear respectively. A drive motor is fixedly installed on the left side of the drive box, and the left end of the first rotating shaft is installed on the right output end of the drive motor through a transmission shaft.
[0010] Furthermore, a fourth gear is fixedly installed at one end of each of the two stirring rods that are close to each other, and the two fourth gears are simultaneously meshed with a fifth gear, which is fixedly mounted on the second rotating shaft.

[0013] Furthermore, a feed pipe is fixedly inserted into the right end of the top of the top cover.
[0014] This invention provides a highly efficient repair device for microbial repair of concrete cracks. It has the following beneficial effects:
[0015] 1. This high-efficiency repair device for microbial repair of concrete cracks involves adding microbial repair slurry into a material tank through a feed pipe. Then, a drive motor is activated to rotate the first rotating shaft, which in turn rotates the first gear. The first gear, through a third gear, drives the connecting rotating drum, which in turn rotates the mixing box. The mixing box, through a third mounting sleeve and a mixing rod, causes the mixing frame on the fixed block to rotate axially around the connecting rotating drum, thus stirring the microbial repair slurry in the material tank. This prevents problems such as stratification and sedimentation caused by static setting, ensuring uniform mixing of microbial cells and cementing components, maintaining the stability of the slurry composition. The uniform slurry environment ensures microbial activity, promotes the efficiency of their metabolism in producing cementing substances such as calcium carbonate, and improves the density of crack filling, effectively enhancing the practicality of the device.
[0016] 2. This high-efficiency repair device for microbial repair of concrete cracks involves starting the drive motor so that the first gear drives the connecting drum to rotate via the third gear. Simultaneously, the first gear drives the second shaft to rotate via the second gear. The second shaft drives two fourth gears to rotate via the fifth gear. The fourth gears drive the mixing frame to rotate around the mixing rod axis via the stirring rod and the fixed block. This causes the mixing frame to revolve around the connecting drum axis and rotate on its own axis around the stirring rod axis, further improving the mixing effect, preventing particle deposits from clogging the feed pipe or injection head, reducing the device failure rate, extending its service life, and further improving the practicality of the device.
[0017] 3. This high-efficiency repair device for microbial repair of concrete cracks can stabilize the temperature of the microbial repair slurry in the hopper by setting a heating jacket and an insulation jacket, avoiding the influence of environmental temperature difference on the activity of microorganisms, maintaining their metabolic function, enhancing the reliability of the device in different environments, and effectively improving the applicability of the device.
