The invention relates to a splicable antenna module for wide-area coverage, including a radiation unit, a radio frequency connector, an N-gon splicing substrate, an angle-adjustable splicing connector, a heat dissipation module, and a TR module, wherein the angle-adjustable splicing connector Including the splicing connector 1, the splicing connector 2 and the rotation locking mechanism. The present invention proposes a splicable antenna module with integrated electromechanical design. The N-gon splicing substrate is not only the installation and fixing substrate of the radiation unit, the angle-adjustable splicing connector and the heat dissipation module, but also the splicing of the antenna module into a plane or conformal shape. Based on the splicing configuration of the array antenna, by adjusting the angle a of the angle-adjustable splicing connector, the splicing angle requirement of the array antenna can be realized. The invention realizes the rapid splicing of the skeletonless plane and the conformal array antenna, and the function of adjusting the angle of the conformal antenna. The size of the antenna module can be adjusted according to requirements, so that the size of the whole array antenna after splicing can be adjusted and has versatility.

The assembling portion is provided with a sliding groove which is open on one end. The inner wall of the sliding groove is provided with electrode strips. The partition comprises a main board and an edge-wrapping structure. The main board is provided with a humidifying assembly. The main board is in a holding cavity of the box. The edge-wrapping structure is arranged on the outer side of the assembling portion. The edge-wrapping structure can slide on the assembling portion. The edge-wrapping structure comprises a baffle, the side of the baffle, facing the sliding groove, is provided with electrode columns. The top ends of the electrode columns contact with the electrode strips. The electrode columns are electrically connected with the humidifying assembly. In the technical scheme, the main board is provided with the humidifying assembly, and the main board can move in the box, so that multi-wet-area storage space of the drawer is realized, and the size of the storage space can be adjusted at will. Through cooperation of the sliding groove and the baffle, the electrode strips and the electrode columns are isolated from the external, thereby improving security of the humidifying assembly when the humidifying assembly humidifies.

The invention discloses a hydrophobic silica gel composite resin-based VOC adsorbent. A synthetic method for the adsorbent comprises the following steps: (1) pretreatment of silica gel; (2) silanization of the surface of the silica gel; (3) preparation of a polymer precursor of a resin and the silica gel: a step of dissolving a divinylbenzen monomer and the initiator azobisisobutyronitrile in tetrahydrofuran in an ice water bath, carrying out mixing under stirring so as to obtain a resin polymer fluid, and adding a certain amount of the resin polymer fluid in the silane-modified silica gel drop by drop to form moist silica gel; and (4) preparation of the hydrophobic silica gel composite resin-based VOC adsorbent: a step of conveying the moist silica gel prepared in step (3) to a crystallization kettle, carrying out crystallization at a temperature of 100 to 150 DEG C for 10 to 50 h so as to obtain a sample and drying the sample at a temperature of 50 to 110 DEG C for 5 to 10 h so as to obtain the adsorbent. With the synthetic method in the invention, the surface of the silica gel presents hydrophobicity, the size of a silica gel channel can be reduced, a specific surface area of the silica gel is increased, and preferential adsorption capability of the silica gel in absorption of VOC gas is greatly improved, so the hydrophobic silica gel composite resin-based VOC adsorbent has wide application prospects.

The invention relates to a fixation plate combined structure of a case. The fixation plate combined structure comprises a fixation plate part and multiple locking components, wherein the fixation plate part is composed through splicing of a first plate body and one or more than one second plate bodies; multiple raised plates extend from the first plate body or the second plate body; multiple through holes are formed in the second plate body or the first plate body; each raised plate passes through and is clamped in each through hole; multiple first locking holes are formed in the first plate body; multiple second lock holes are formed in the second plate body; and each locking component passes through and is fixed to each first locking hole and each second locking hole. In this way, through adjustment of quantity of the second plate bodies connected with the first plate body, the size of the fixation plate body can be adjusted, so that the fixation plate combined structure has the advantages that the size is changeable, use is convenient, and economic cost is saved.

The invention discloses a biomimetic synthesis method of a size-controllable prismatic bismuth phosphate photo-catalyst. The biomimetic synthesis method comprises the following steps: (1) dissolving bismuth nitrate pentahydrate into a nitric acid solution of which the molar concentration is 1mol / L, uniformly stirring, adding gelatin, and continuously stirring for 2 hours to obtain a mixed solution; (2) adding sodium dihydrogen phosphate of which the molar quantity is equal to that of bismuth nitrate pentahydrate into the mixed solution obtained in the step (1), stirring for 0.5 hour, regulating the pH value of the system to be 1-7 by using ammonia water, continuously stirring for 0.5 hour, transferring to a hydrothermal reaction kettle, performing hydrothermal reaction for 6-24 hours at 140-210 DEG C, performing centrifugal separation, washing, and performing vacuum drying for 12 hours at 60 DEG C to prepare the prismatic bismuth phosphate photo-catalyst. The biomimetic synthesis method disclosed by the invention can avoid the synthesis in an organic solvent or a mixed solvent of an organic reagent and water, and also can avoid regulating the sizes of particles by using the organic solvent which is harmful to the environment, so that the biomimetic synthesis method is a synthetic method which is low in cost and is environment-friendly.
