This invented ionic battery pole group includes strip-like negative pole plates, multiple sheet positive pole plates, membranes, ears of positive and the negative poles, in which, the hems at one end of the negative plates are fixed to a lamination state, the positive plates are set at the folded place of the negative and their collectors are fixed together, the lamination is even, a positive pole plate covered by the membrane is set at each folded place, the ear of the negative is fixed on the collector of the negative, the ear of the positive is fixed at the collector of any positive pole plate and the entire group is wrapped by a membrane. This invention also provides a manufacturing method for the pole group, which solves the problem of positioning of the pole plates and their alignment.

The invention discloses a quick connecting positioning structure for assembling offshore buoyancy tanks. The quick connecting positioning structure comprises connecting positioning seats and connecting positioning components. The connecting positioning seats are arranged on buoyancy tank modules; at least two connecting positioning seats are mounted on each connecting surface of the corresponding buoyancy tank module, and hinge pin holes which are perpendicular to the connecting surfaces are formed in the connecting positioning seats; the connecting positioning components are provided with hinge pins and flexible ropes, and the flexible ropes are connected with the hinge pins; each connecting positioning component is penetratingly arranged in the hinge pin holes of the two corresponding connecting positioning seats which are opposite to the two corresponding to-be-assembled buoyancy tank modules, and each two corresponding buoyancy tank modules are connected with each other by the corresponding connecting positioning components to be close to each other. The quick connecting positioning structure has the advantages that each two corresponding to-be-assembled buoyancy tank modules can quickly move to assembling connecting positions and can keep stable at the relative positions; connectors can be conveniently connected with one another after the buoyancy tank modules are connected and positioned, and the buoyancy tank modules can be integrally connected with one another by the connectors.

The invention discloses an assembled insulating platform. The assembled insulating platform comprises an upper platform body and a lower platform body, wherein the upper platform body is connected with the lower platform body through hinges; and the upper platform body and the lower platform body are of trapezoidal structures with at least one sides gradually shrinking from bottoms to tops, the inner parts of the upper platform body and the lower platform body are of hollow structures, and the upper platform body and the lower platform body are connected with an upper drawer and a lower drawerwhich can be drawn and pulled. The assembled insulating platform is composed by assembling, is provided with a plurality of storage drawers and is used for placing special tools, and manual operationis facilitated.

The invention discloses a buried storage battery lead fixing device and a fixing method thereof, discloses a fixing ring for fixing, and discloses a corresponding fixing method. According to the fixing device and the fixing method, batteries can be sealed, gaps between battery cases and leads can be sealed, and the service life of the batteries can be effectively prolonged; and the leads outside the fixing ring can be changed in time during the damage without taking out the battery parts buried in the ground. The method provided by the invention is simple to operate, suitable for manual operation and suitable for industrial mechanical operation, is capable of ensuring the airtightness between the battery cases and the leads, and can be widely applied to buried batteries and related industries.

The invention relates to a coated sand mold loading and positioning installation template. The coated sand mold loading and positioning installation template comprises an installation template body. Guiding holes are formed in the periphery of the installation template body. A fixing hole is formed in the middle of the installation template body. Bar-shaped hole path sets and circular hole path sets are symmetrically arranged on the portion, on the two sides of the fixing hole, of the installation template body. The coated sand mold loading and positioning installation template is simple in structure and suitable for a plurality of coated sand molds. Installation templates matched with different coated sand molds do not need to be produced when the different coated sand molds are used. Theresearch and development and production cost of enterprises is saved. The coated sand mold loading and positioning installation template is easy to install and suitable for manual operation, can be applied to the plurality of coated sand molds after one-time installation of the coated sand mold loading and positioning installation template on equipment like a core shooter, saves manpower and working time, and effectively improves working efficiency.

The invention discloses a rigid connector of an offshore buoyancy tank system. The rigid connector comprises a pulling rod which is arranged in a vertical channel in a penetrating mode. A lower wedge hook is arranged at the lower end of the pulling rod. A limiting sleeve is fixedly connected with the pulling rod. A cylindrical nut is arranged at the upper end of the pulling rod. A strip-shaped upper wedge hook is arranged on the cylindrical nut in a sleeved mode. The upper wedge hook and the lower wedge hook are arranged symmetrically up and down. At least two wedge hook storing bases and at least two upper wedge hook connecting bases are arranged below the upper wedge hook. One upper wedge hook connecting base and two upper wedge hook storing bases are fixed on the upper face of a buoyancy tank A. The other upper wedge hook connecting base is fixed on the upper face of a buoyancy tank buoyancy tank B. Two lower wedge hook storing bases and two lower wedge hook connecting bases are arranged above the lower wedge hook. A limiter matched with a limiting sleeve is fixed on the buoyancy tank A. All splicing operation can be carried out on the upper surfaces of the buoyancy tanks, maintaining of the connector is carried out on the outer portions of the buoyancy tanks, easiness and convenience are achieved, the structure is simple, and manufacturing cost is low.

The invention relates to an air compartment structure capable of reducing negative-pressure fluctuation of impurity suction of a rotor spinning machine. The air compartment structure comprises an air compartment, the front end of the air compartment is connected with an impurity suction air pipe, the rear end of the air compartment is connected with an impurity suction fan, a left filter screen, a right filter screen and a middle partition are fixedly mounted in the air compartment and divide the same into a front portion and a rear portion, and a front half portion of the air compartment is an impurity collection box. The front side face of the middle partition is fixedly connected with a separator, a left filter screen partition and a right filter screen partition are hinged to the left end and the right end of each filter screen, connecting rods are hinged to the middles of the left filter screen partitions and the right filter screen partitions, and the other end of each connecting rod penetrates out of the side wall of the air compartment and is provided with a handle. The air compartment structure is beneficial to impurity deposition, and covered time of the filter screens is prolonged. When an air duct is switched, change of ventilation area is only one half of that of the structure in the prior art, negative-pressure fluctuation is reduced by one half correspondingly, and yarn quality is improved beneficially.
