A manhole wall module for constructing the wall of manhol is disclosed, which features that on its surface there are the concave-convex structures for matching with adjacent modules, it has the preserved holes for pouring concrete or inserting the reinforcing bar in them, and its accessories are used to flexiblly connecte to external pipeline.

The invention discloses a novel rubbish basket which comprises a rubbish basket body. The rubbish basket body is sleeved with a layer of protective jacket. The protective jacket is provided with rails, and the rails are groove-type rails. Sliding blocks are arranged in the rails and can slide in the rails, and the sliding blocks are provided with plastic clips. Moreover, a containing box is further arranged at the bottom of the rubbish basket body. According to the novel rubbish basket, the protective jacket is arranged outside the rubbish basket body, so that the firmness of the rubbish basket body is guaranteed, and the rubbish basket is not liable to be damaged; besides, the sliding blocks capable of sliding are arranged in the protective jacket, and the sliding blocks are provided with the plastic clips, in this way, when a large-sized rubbish bag is used, an opening of the rubbish bag is clamped onto the plastic clips, then the position is adjusted through the sliding blocks, and the large-sized rubbish bag can still be used ingeniously.

The invention relates to a high-toughness fabric fiber resin road manhole cover, which is made of resin, polystyrene, styrene, O butyl, methyl ethyl ketone, aggregate and fabric edge leftover according to the weight ratio of 1:0.4:0.8:0.025:0.015:4-6:0.25. A method of making the manhole cover includes: primarily mixing the materials at the temperature of 143 DEG C and under 160T pressure and placing the mixture into a mould with a steel ribbed movement frame, stripping after 6-8 minutes, and obtaining a resin fiber grate manhole cover or resin fiber road inspection manhole cover. By using the fibers of the fabric edge leftover, impact resistance of the manhole cover is improved greatly, and bearing capacity is improved. The high-toughness fabric fiber resin road manhole cover has the advantages of shock absorption, noise reduction, corrosion resistance, insulation, wear resistance, weather proofing, light weight, and low cost.

The invention discloses a stator wire rod insulation onsite repairing method for a large generator. The stator wire rod insulation onsite repairing method uses materials of a mica tape with low dosage of adhesive, a mica tape with high dosage of adhesive, room-temperature cured epoxy resin adhesive, a pre-impregnated glass tape (PG band) and the like; a main insulation damaged part of the stator wire rod is repaired on the site of accident of the generator; through a reasonable and reliable repairing process, the main insulation repairing of the wire rod is completed within a short time; it is ensured that the repaired stator winding can satisfy long-term, stable and reliable operational requirements of a machine set; meanwhile, a technological process of stator wire rod insulation onsite repairing for the large generator is specified; all repaired machine sets are re-input into operation; the repaired winding is excellent and reliable in insulation performance; and compared with a former generator accident treatment method, the stator wire rod insulation onsite repairing method can ensure the repairing quality, avoid disassembling and replacing of the stator wire rod, save a huge repairing cost, greatly shorten the rush repairing period, and has great economic benefit and social benefit.

The invention relates to a soil probe for detecting the water of soil based on time domain transmission. The soil probe comprises a probe sensing board, a water sensing and transmission line and a shell; the front end of the probe sensing board is provided with a front through hole, the probe sensing board is a 3-layer PCB, the middle portion of the water sensing and transmission line traverses through the front through hole, the water sensing and transmission line is welded to signal lines on the upper surface and the lower surface of the probe sensing board to form a signal transmission channel; the shell is made of a hard metal, the front side edge, the left side edge and the right side edge of the probe sensing board are wrapped with the shell, and the upper surface and the lower surface of the probe sensing board are exposed to sense water information; and the metal shell is connected with the ground lien of the probe sensing board. The soil probe has a simple structure and realizes plug-and-play; and after the soil probe is plugged to soil, the probe sensing board and the water sensing and transmission line fully contact the soil, and can sensitively sense the water information. Connection of the metal shell with the ground line of the sensing board guarantees fastening of the probe, avoids interference to high frequency signals, and improves the reliability of sensors.

The invention provides a method for preparing an electrode of ZIF-derived CoMoO4. the method is characterized in that the method uses a high temperature calcined ZIF-67 as a precursor to prepare CoMoO4 by hydrothermal method., that steps are as follow: (1) molybdate and a compound containing a Co salt are taken and stirred in deionized water until the molybdate and the compound contain the Co saltare dissolved; (2) a small amount of ZIF-67 power are added, stirred to a homogeneou solution; 3, that mixture is transferred to a reaction kettle, and the mixture is cooled to room temperature afterreaction for 2h; (4) alternately cleaning and drying are performed for 24h; (5) Ultrasonic cleaning is performed for 30 min, deionized water cleaning and ultrasonic are performed, drying is performedfor 12 h; 6) that graphite paper is dried at constant temperature, the required material is ground in a mortar, a small amount of solvent is added, uniformly dropping on the dried sheet layer, and then drying is performed, and 7) a regular-shaped electrode of ZIF-derived CoMoO4 is performed. The invention overcomes the problems of poor stability and small specific capacitance of metal oxide electrode in the prior art, and provides a preparation method of CoMoO4 derived from metal oxide electrode material ZIF with high specific capacity and good stability.

The composition of environment-protecting green vegetation concrete is formed from cement, broken stone, water reducer, acid polymer, chemical fibre and water, its mixing ratio is as follows: water, cement; broken stone is 0.25-0.29:1:4.45; addition amount of water reducer is 3%-5% of cement weight, acid polymer is 10%-20% of weight of water, and for each cubic meter of concrete 0.9-1.2 kg of chemical fibre can be added. Said invented green vegetation concrete can be used for protecting and greening river embankment, lake embankment, building wall and roof. The compression strength of said invented green vegetation concrete can be u pto 15 Mpa-18 Mpa.
