The invention relates to a preparing method of a piled carved ceramic plate decorative picture. The method comprises following steps: firstly, at least one portion of the surface of a ceramic plate is subject to sand blasting treatment, a glaze layer of at least one portion on the surface of the ceramic plate is removed, and a dull polish face is formed on at least one portion on the surface of the ceramic plate; secondly, the frosted surface of the prepared ceramic plate is cleaned and dried, white glaze piled printing is carried out, and a three-dimensional piled glaze pattern is formed; thirdly, a color patter is sprayed and printed on the surface of the ceramic plate prepared in the second step; fourthly, the ceramic plate prepared in the third step is sintered. Through the sand blasting process treatment, the color attaching force is increased, the piled glaze technology is added to form the three-dimensional piled glaze pattern, and the 3D effect is achieved, the color pattern is sprayed and printed, and the colorful decoration effect is formed.

The invention relates to a transformer substation assembled type cable groove body and a cable channel system thereof. The transformer substation assembled type cable groove body is formed by connecting waterproof groove bodies with a U-shaped cross section in sequence, and is characterized in that: a U-shaped moisture-proof supporting body is arranged in an inner cavity of each U-shaped groove body; and the U-shaped groove bodies are oppositely buckled with the U-shaped moisture-proof supporting bodies, and a cable paving channel is formed between the U-shaped groove bodies and the U-shaped moisture-proof supporting bodies. The cable channel system applying the transformer substation assembled type cable groove body comprises a base body, wherein the transformer substation assembled type cable groove body is arranged on the base body; and the base body comprises a soil filled layer and a water filtering layer arranged on the soil filled layer. The transformer substation assembled type cable groove body and the cable channel system using the same, provided by the invention, have the outstanding substantive characteristics as follows: the U-shaped groove bodies are oppositely buckled with the U-shaped moisture-proof supporting bodies, so that the cable paving channel has moisture-proof and waterproof effects; and supporting rods, moisture-proof separating bars, top air vents or ventilating grooves, middle air vents or ventilating grooves and the like are arranged, so that water, such as water vapor in the cable paving channel, can be discharged in time.

An atrium barrier handrail structure with a hidden lamplight, comprising a main skeleton (1) fixedly installed on a floor concrete layer, a secondary skeleton (2) and a covering keel (3) which are fixedly installed on the main skeleton (1), a base layer plate (4) fixedly installed on the covering keel (3), a handrail (5) fixedly installed at the top of the base layer plate (4), and lights (6) hidden in the base layer plate (4) and / or in the handrail (5), the main skeleton (1) and the secondary skeleton (2) both being steel skeletons. An installation process for an atrium barrier handrail structure with a hidden lamplight. The handrail structure has light weight, simple construction, and good decorative effect.

The present invention relates to a bamboo-shaped free turning junction box. The bamboo-shaped free turning junction box comprises an insulated center cylinder and a plurality of outer cylinders rotationally sleeving on the center cylinder in order; three first raised lines are arranged at the outer portion of the center cylinder along the axis direction; the three first raised lines perform equal division of the outer circumference of the center cylinder; the outer surface of the center cylinder between two adjacent first raised lines is provided with arc first conducting strips; three second raised lines are arranged at the inner circles of the outer cylinders; the three second raised lines perform equal division of the circumference of the inner circles of the outer cylinders; the second raised lines are coated with second conducting strips; the second conducting strips are in respective sliding electrical contact with the first conducting strips; the center cylinder is provided with a main firing line hole, a main null line hole and a main ground wire hole along the axis direction; and the outer cylinders comprise branch firing line holes, branch null line holes and branch wire holes along the radial direction of the outer cylinders. The bamboo-shaped free turning junction box can allow each branching to have a free rotation angle approach to 120 degrees to facilitate wiring, and has moistureproof, waterproof and convenient dismounting and mounting, and the service life of the wire is long.

The present invention relates to a preparation method for a decorative picture of a thousand-layer carved ceramic plate. The method comprises: 1) covering a layer of protective film on a surface of a ceramic plate; 2) using a laser carving machine to carve edge lines of a predetermined pattern on the surface of the ceramic plate, wherein the pattern comprises a plurality of parts; 3) removing the protective film gradually from each part of the pattern, and carving with sandblast until a complete multi-layer carved pattern is formed, wherein a sandblasting pressure adopted in the sandblasting carving is 1-10 kg / m<3>, and a flow rate is 5-20 m<3> / min; 4) sandblasting the surface of the ceramic plate to remove a glazed layer on the surface of the ceramic plate and form a frosted surface, wherein the sandblasting pressure is 1-10 kg / m<3>, and the flow rate is 5-20 m<3> / min; 5) after the frosted surface of the ceramic plate prepared in the step 4) is cleaned and dried, jet printing and drawing the pattern, and then jet printing a protective glazed layer; and 6) sintering the ceramic plate prepared in the step 5) rapidly.

The invention relates to a preparation method of a ceramic plate decorative painting through colored engraving. The method comprises the following steps: 1), a protective film is attached to the surface of a ceramic plate; 2), sidelines of a specified figure are engraved on the surface of the ceramic plate by a laser engraving machine; 3), the protective film at a to-be-etched part is removed so as to expose an engraving surface; 4), the surface of the ceramic plate is eroded by an abrasive material at a high flow rate, so that an uncolored solid figure is formed through engraving on the ceramic surface with the protective film removed, the pressure is 1-10 kg / m<3>, and the flow is 5-20 m<3> / min; 5), sand blasting is at least performed on a to-be-colored part of the surface of the ceramic plate so as to at least remove a glaze layer of the to-be-colored part and form a frosted surface, the sand blasting pressure is 1-10 kg / m<3>, and the flow is 5-20 m<3> / min; 6), the frosted surface of the ceramic plate prepared in the step 5) is cleaned and dried, a pattern is spray-printed and drawn, and a protective glaze layer is spray-printed; 7), the ceramic plate prepared in the step 6) is sintered rapidly.
