This utility model provides a precast component for wet joints of precast T-beams that does not require formwork removal, comprising a first precast component and a second precast component, which are staggered along the wet joint of the precast T-beam. The advantages of this utility model are that by using the first and second precast components directly as bottom formwork installed at the bottom of the wet joint, it saves on the installation and use of formwork, eliminating the need for formwork removal. The structure is simple, operation is convenient, and construction progress is accelerated. The first and second precast components and the precast T-beam can be interlocked and assembled without the need for joint sealant, ensuring the appearance quality of the concrete after the wet joint is completed and reducing safety hazards.

The application discloses a kind of laser-assisted drilling rock breaking intelligent control system and method, comprising: perception module, for obtaining the state information of each component of laser drill, tunneling parameter and drill drilling force;Decision module is used to determine whether the operation of laser drill is normal according to the state information of each component of laser drill, determine the surrounding rock grade under the current tunneling state according to tunneling parameter, and determine the drilling pressure difference between each drill tooth according to drill drilling force, and determine whether the drilling direction of drill is deviated by the drilling direction deviation occurrence threshold value;Execution module is used to determine whether to issue alarm and close laser drill according to the operation of laser drill determination result, select to start corresponding drilling mode according to surrounding rock grade, and adjust laser beam exit angle according to the drilling direction of drill determination result.Advantages: improve tunneling efficiency, ensure drilling stability and safety.

The embodiment of the utility model provides a kind of heat exchange device, battery module and electrical equipment, it is related to battery pack liquid cooling plate technical field.The heat exchange device includes heat exchange plate and at least one heat conduction plate, the inside of heat exchange plate is hollow cavity, heat exchange plate is provided with liquid inlet and liquid outlet, and liquid inlet and liquid outlet are all communicated with cavity.The sidewall of heat exchange plate is provided with at least one first slot;Each first slot is used to insert at least one heat conduction plate, to realize the connection of heat conduction plate and heat exchange plate;Heat transfer is realized between heat conduction plate and heat exchange plate.Cooling liquid is passed into heat exchange plate from liquid inlet, and flows out from liquid outlet, and the heat transferred by heat conduction plate is quickly absorbed by cooling liquid flowing inside, and heat exchange is carried out.This design does not need to set up heat exchange pipeline with liquid path between every two adjacent batteries, to reduce the space occupied by heat exchange device in battery module.In addition, by setting first slot, heat conduction plate can be conveniently and quickly installed and disassembled.
