The invention relates to the technical field of battery thermal management, in particular to a battery replacement battery thermal management device and method. Comprising a heat dissipation shell, the top of the heat dissipation shell is detachably provided with a sealing cover, the heat dissipation shell is fixedly connected and communicated with a liquid inlet pipe and a liquid outlet pipe, the heat dissipation shell is fixedly connected with a first motor, an output shaft of the first motor is fixedly connected with a gear, the heat dissipation shell is rotationally connected with a gear ring meshed with the gear, the gear ring is fixedly connected with an extrusion block, and the extrusion block is fixedly connected with a motor. An inner cylinder is fixedly connected to the inner wall of the heat dissipation shell, a push injection rod is slidably connected to the inner cylinder, a trigger rod is fixedly connected to the push injection rod, a through hole is formed in the push injection rod, a first one-way valve is arranged in the through hole, a through hole is formed in the inner cylinder, and a second one-way valve is arranged in the through hole. The cooling liquid on the outer side of the heat dissipation shell is extracted into the inner cylinder through the push injection rod and injected to the periphery of the battery, and the situation that the cooling liquid on the outer side of the heat dissipation shell cannot make contact with the battery, and consequently the cooling liquid cannot be fully utilized is avoided.

A push rod device for opening and closing mechanical doors, relating to the field of mechanical door and window switches, includes a fixed rod, a hinge rod, a push rod assembly, and a foot pedal assembly. The fixed rod is fixed to the upper part of the inner surface of the door panel. The left end of the hinge rod is hinged to the door frame, and the lower right end of the hinge rod is slidably mounted on the fixed rod via a screw. The diameter of the middle part of the hinge rod is larger than the diameters of the upper and lower ends. The push rod assembly includes a push rod and a fixed block. The fixed block is fixed to the door panel, and the push rod is slidably mounted inside the fixed block. The upper end of the push rod has a top block that corresponds vertically to the screw. The plug on the lower end of the push rod is inserted into the foot pedal assembly. This utility model has a simple structure and is easy to use, avoiding the inconvenience and safety hazards of climbing ladders to open and close doors.

The embodiment of the invention provides a method for automatically processing recharge staging presentation, which comprises the following steps of: responding to received recharge order data, matching a corresponding recharge rule, judging whether a recharge order simultaneously meets the conditions of first-period presentation amount immediate return and presentation amount regular return set in the recharge rule, and if so, executing the recharge process; according to the recharging order data and the recharging rule, calculating to obtain the given amount of each period and the corresponding period arrival time; transferring the first-time presentation amount to a member account, and automatically generating a corresponding staging presentation task according to the remaining presentation amount and the staging arrival time; automatically executing a corresponding staging presentation task at each staging arrival time, and transferring the remaining presentation amount to a member account one by one; and meanwhile, the execution condition of the staging presentation task of each recharging activity is monitored, and all staging presentation tasks related to the current recharging activity are terminated until it is confirmed that all the remaining presentation amounts are transferred to the member account in each period.

The utility model discloses a power transformation maintenance engineering ladder which comprises two groups of vertical rods, a plurality of groups of cross rods are fixed between the vertical rods at equal intervals, rubber sleeves are sleeved at the bottom ends of the vertical rods, supports are mounted on one side walls of the vertical rods, a bearing shaft is arranged between the supports, a rotating block is sleeved in the middle of the bearing shaft, and the rotating block is fixedly connected with the vertical rods. Limiting rings are arranged at the two ends of the rotating block correspondingly, and a fastening bolt is installed on one side wall of the rotating block. The tool box has the beneficial effects that by arranging the bearing shaft, the rotating block, the rotating shaft and the tool box body, in the using process, a worker can rotate around the bearing shaft through the rotating block to turn over the tool box body, and then the tool box body is adjusted to the horizontal position under the action of the rotating shaft; and therefore, temporary placement positions are provided for parts disassembled in the maintenance process through the tool box, the situation that workers are not changed is avoided, and the maintenance efficiency and the using effect of the device are improved.

The utility model relates to the technical field of preparation of eutectic glucosamine sodium sulfate, and discloses a quantitative adding device for preparation of eutectic glucosamine sodium sulfate, which comprises a bottom plate, a hydraulic cylinder is fixedly connected to the top of the bottom plate, and the output end of the hydraulic cylinder is fixedly connected with a mounting frame. The top of the mounting frame is fixedly connected with a discharging box, one side of the discharging box is fixedly connected with a first motor, and an output shaft of the first motor is fixedly connected with a rotating shaft through a coupler. According to the quantitative adding device for preparing the eutectic glucosamine sodium sulfate, when the eutectic glucosamine sodium sulfate is quantitatively added, not only can the eutectic glucosamine sodium sulfate be scattered, but also the eutectic glucosamine sodium sulfate can be pushed to be discharged during discharging; and the condition of blockage caused by low blanking speed of the eutectic glucosamine sodium sulfate salt during addition is avoided, the use effect is further improved, and invariability of preparation and addition is avoided.

The utility model relates to an automobile key box mounting structure and an automobile. The utility model discloses an automobile key box mounting structure. A key box is mounted outside an automobile. The utility model further provides a vehicle which comprises the automobile key box installation structure. The automobile spare key box solves the problem that a user cannot open an automobile door in time under the condition of insufficient electricity due to the fact that the automobile spare key box is installed in an automobile.
