8results about How to "Solve the disassembly problem" patented technology

This utility model relates to the field of inverter installation technology and discloses a mounting bracket for micro-inverters. The bracket includes a mounting frame with a disassembly mechanism on its top and a locking mechanism on its right side. The micro-inverter body is mounted on top of the disassembly mechanism, which includes a long slot fixedly connected to the top of the mounting frame. This mounting bracket for micro-inverters, through its disassembly mechanism, enables tool-free and highly efficient disassembly of the micro-inverter body. The user cranks a handwheel to drive a worm gear, which in turn drives a cam, releasing the mechanical limit on the insertion sleeve. This allows the entire inverter unit (including the long protrusion, middle protrusion, and insertion sleeve) to be safely pulled out of the long slot by hand. The entire process requires no external tools, avoiding the loss and corrosion of small parts (such as bolts) and greatly improving the efficiency and convenience of maintenance and repair, solving a long-standing on-site disassembly problem.

This invention relates to a rapid disassembly and assembly method for fuel cell stacks, belonging to the field of fuel cell technology. The method uses a disassembly and assembly module composed of pull plates and lifting devices to disassemble and replace faulty battery unit modules in a fuel cell stack. Specifically, it includes the following steps: installing pull plates on adjacent modules of the faulty battery unit module; placing lifting devices on both sides of the faulty battery unit module, with the mounting surface and working surface of the lifting devices abutting against the pull plates on both sides; activating the lifting devices to drive the adjacent modules of the faulty battery unit module away from each other, leaving space between the adjacent modules for battery unit module replacement; replacing the faulty battery unit module, removing the lifting devices, and restoring the fuel cell stack. Compared with existing technologies, this invention can achieve rapid disassembly and replacement of faulty battery unit modules inside a fuel cell stack without compromising the overall pre-tightening force and airtightness of the stack.

The application discloses a large-bore diesel engine main bearing cover dismounting device and dismounting method. The device comprises a hoisting unit, a lower slide rail assembly and a main bearing cover support unit. The hoisting unit is fixed on the upper part of the frame on both sides. The lower slide rail assembly is supported on the oil pan rib plate. The support rod of the main bearing cover support unit is vertically supported on the both ends of the cross beam. The upper end is fixed with the lower end of the main bearing cover screw. The lower end is hinged with the both ends of the cross beam. The top block of the main bearing cover support unit is fixedly connected with the lower center of the main bearing cover. The dismounting method comprises the following steps: 1) completing installation; 2) using the hydraulic stretcher to lengthen the main bearing cover screw to unload the main bearing cover nut; and 3) using the main bearing cover support unit to dismount the main bearing cover. The application significantly improves the work efficiency and operation safety of the main bearing cover dismounting, greatly reduces the labor intensity of the main bearing cover dismounting, and solves the problem of the main bearing cover dismounting of the large-bore diesel engine.

This invention discloses a fan cleaning device and a range hood. The fan cleaning device includes: a fan, which includes a volute housing with an air inlet formed thereon, and a mesh cover with mesh openings at the air inlet; and a cleaning mechanism for cleaning the mesh cover. The cleaning mechanism includes a cleaning head array. When the fan is in operation, the cleaning head array is located outside the fan and opposite the mesh cover. When the fan is in cleaning mode, the cleaning head array can pass through the mesh openings to scrape away grease from the walls of the mesh cover that define the mesh openings. Compared with the prior art, the advantages of this invention are: by setting the cleaning head array so that it is located outside the fan when the fan is working normally, the impact on the airflow of grease is reduced. When the fan needs cleaning, the cleaning head array contacts the mesh cover by scraping, which can directly act on the mesh cover's openings, restore the original flow area, maintain airflow, reduce noise, and has low energy consumption without heating, and also avoids the side effects associated with high-temperature cleaning.

The utility model relates to the technical field of oil replacement of looms, and discloses a water jet loom convenient to replace engine oil, which comprises loom equipment, an engine oil replacement mechanism is arranged on the loom equipment, a mounting base is fixedly connected to the inner wall of the loom equipment, a fixed seat is mounted above the mounting base, and the engine oil replacement mechanism comprises a handle. A bearing handle is fixedly connected to the bottom end of the handle, one end of a connecting plate is movably clamped to the inner side of the bearing handle, a deflection axis rod is hinged to the joint of the bearing handle and the connecting plate, and a supporting axis rod movably penetrates through the bottom end of the bearing handle and is movably hinged to the fixing base. According to the engine oil replacing mechanism, an operator only needs to hold the handle to apply external force, a series of components can be driven to move cooperatively, the oil outlet channel is opened or closed easily, complex components do not need to be disassembled, the oil replacing operation process is greatly simplified, and the oil replacing efficiency is remarkably improved.

The utility model discloses a reaction kettle baffle plate, including kettle body and baffle plate, the baffle plate is provided with a plurality of groups and is equipped with the quick-mounting mechanism with kettle body between, quick-mounting mechanism includes insert link, fixed sleeve, neck, abutting plate, chute, sliding sleeve, hinge plate and limit mechanism, insert link is fixed in the outer wall of baffle plate, fixed sleeve is fixed in the inner wall of kettle body, and the fixed sleeve is fixed in the inner wall of kettle body.
