The utility model discloses an auxiliary device for hub assembly, which relates to the technical field of automobile assembly, and comprises a parallelogram structure formed by hinging the end parts of a first suspender, a second suspender, a third suspender and a fourth suspender, and the adjacent third suspender and fourth suspender extend and bend downwards to respectively form a vertical second suspension arm and a vertical first suspension arm; rotary clamping mechanisms are respectively mounted at the end parts of the first lifting arm and the second lifting arm; hanging rings are arranged at hinged ends of the first hanging rod and the second hanging rod; the rotary clamping mechanism comprises a bearing sleeve, a bearing, a connecting rod and a rotary clamping jaw; the rotary clamping jaw is fixedly connected with a connecting rod, the connecting rod penetrates through a bearing sleeve and is locked and fixed by a nut, a bearing is sleeved on the connecting rod, and the bearing sleeve is sleeved on an outer ring of the bearing; and the bearing sleeves on the left and right sides are respectively connected with the first suspension arm and the second suspension arm. The hub turnover device solves the problems of low production efficiency, high labor intensity and unsafety in the carrying process due to the fact that hubs are directly turned over manually in the existing hub assembly process.

This invention relates to a bifacial photovoltaic (PV) power generation module and a PV power generation system. The bifacial PV power generation module includes a mounting frame, photovoltaic cells, a first reflective mirror, and a second reflective mirror. A first mounting plate and a second mounting plate are connected to form a V-shape. n rows of first photovoltaic cells are mounted on the first mounting plate to form a first photovoltaic cell group, and n-1 rows of second photovoltaic cells are mounted on the second mounting plate to form a second photovoltaic cell group. n-1 rows of first reflective mirrors are mounted on the first mounting plate, and n rows of second reflective mirrors are mounted on the second mounting plate. The first reflective mirrors face the second cell group, and the second reflective mirrors face the first cell group. This invention's bifacial PV power generation module increases the amount of sunlight received by the photovoltaic cells, fully utilizing the power generation characteristics of both reflected and direct sunlight from the bifacial cells. It can generate electricity throughout the sunshine period, thus achieving higher power output and allowing users to obtain a higher return on investment.

The invention relates to the technical field of federated learning and block chains, in particular to a federated learning incentive method and system based on two-stage commitment and a block chain. According to the technical scheme, the federal learning excitation method based on the two-stage commitment and the block chain comprises the following steps: a reputation evaluation step: dividing interaction behaviors of a client into three conditions of positive interaction, negative interaction and uncertain interaction according to a deviation degree between each round of uploading model updating and a global updating direction of the client, the reputation value of the client is calculated by adopting a subjective logic-based Bayesian reasoning method, and the influence of long-term interaction on the reputation is weakened by introducing a time decay mechanism. By introducing the block chain and the dual-stage commitment mechanism, it is ensured that the server cannot deduct the deserved rewards of the client without being found, the publicity, transparency and fairness of the incentive process are ensured, and the trust of each participant is maintained.

The invention discloses a pipeline integrated type hydroelectric generation device which comprises a draft tube, a water inlet pipe fixedly connected to one end of the draft tube, a support fixedly connected to the inner wall of the water inlet pipe, a bulb body fixedly connected to the center of the support, a generator fixedly connected into the bulb body, a rotating wheel shaft fixedly connected to an output shaft of the generator and penetrating out of the end, close to the draft tube, of the bulb body. The end, away from the draft tube, of the bulb body is sealed through a sealing device, a plurality of guide vanes are fixedly connected to the outer wall of the bulb body in the circumferential direction, a through hole is formed in the outer wall of the water inlet tube, and a wire of the generator penetrates through the water inlet tube through the support and the through hole. The invention further discloses a pipeline integrated type hydroelectric generation method. According to the pipeline integrated type hydraulic power generation device and the power generation method, the construction difficulty and the transformation cost of installation and transformation of an existing residual pressure power generation system are reduced, and the energy recycling efficiency is greatly improved.

The utility model discloses a patrolling camera waterproof sliding track, which comprises a camera, a track and a power driving device, the camera and the power driving device are arranged at the bottom of the track, waterproof fixed top plates are respectively arranged on two sides of the track, one end of each waterproof fixed top plate is connected with the track, and the other end of each waterproof fixed top plate is provided with a water retaining sliding groove. The water retaining sliding groove is connected with a waterproof movable top plate, the waterproof movable top plate slides along the water retaining sliding groove, and the power driving device is used for driving the camera to move back and forth along the track and driving the waterproof movable top plate to slide along the water retaining sliding groove. The waterproof top plate adopts a segmented sliding type design, can reduce the width of the track, reduces the manufacturing cost of the track, is easy to assemble and disassemble, and can meet the expectations of short engineering construction period, low investment and high return. According to the utility model, the design of the waterproof top plate and the waterproof shell is adopted, so that the waterproof inspection camera has good waterproof performance, thereby ensuring that the inspection camera can work stably in an outdoor severe natural environment, and prolonging the service life.
