The invention discloses an external thermal insulation board for a building wall. The thermal insulation board comprises a cement plate decorative layer which is arranged on an external layer, a cement plate base layer which is used for connecting the building wall and a sound-proof thermal insulation interlayer which is connected between the cement plate decorative layer and the cement plate base layer; the cement plate decorative layer is formed by the following components which comprise 95 parts of cement, 4 parts of lepiota brunneo-incarnata powder and one part of butterfly orchid petal powder. The thermal insulation board has the advantages of effectively reducing egg reproduction probabilities of worm, moths and the like at the position of the thermal insulation board, greatly reducing the worm breeding rate, effectively avoiding bird excrement polluting buildings due to the facts that the lepiota brunneo-incarnata powder is added to the cement plate decorative layer and birds hardly stay at building tops and at the modeling design position and being good in sound proof effect and good in thermal insulation effect due to the sound proof thermal insulation interlayer.

The invention discloses an insulation board adhered to a building external wall. The insulation board comprises a concrete plate decoration layer positioned on the outer layer, a concrete plate substrate layer used for connecting with the building wall and a soundproof insulation middle layer connected between the concrete plate decoration layer and the concrete plate substrate layer, wherein the concrete decoration layer comprises the following compositions in parts by weight: 95 parts of concrete and 5 parts of lepiota brunneo-incarnata powder. With the adoption of the insulation board, the probability of insects and moths reproducing and laying eggs in the insulation board is effectively reduced, so that the insect breeding rate is greatly reduced; besides, when the insulation board with lepiota brunneo-incarnata powder added to the concrete decoration layer is adopted, birds seldom stay in the top and the style design parts of the building, the situation that the building is polluted by the bird droppings is effectively avoided. Meanwhile, the soundproof insulation middle layer has a remarkable soundproof effect and a good insulation effect.

The invention discloses a novel method for transporting culter living bodies remotely. The novel method comprises the steps of control on transportation water body, rapid cooling treatment, rapid heating treatment, microcapsules adding in a transport tank and other aspects of control. The novel method for transporting the culter living bodies remotely has the advantages that from many aspects suchas culter itself, environment control and the like, the culter body surface has no damage, the survival rate of the culter transportation is effectively improved (reaching up to 90% or above), the sales appearance of the culter is improved, and the freshness of the culter is kept.

The invention discloses a household environment-friendly intelligent sorting trash can, which relates to the technical field of domestic waste treatment. The invention comprises an outer barrel; the inner wall of the outer barrel is respectively fixedly connected with a limit ring and a support frame; the inner wall of the limit ring is fixedly connected with a dehydration barrel through a bearing; the inner wall of the dehydration barrel is fixedly connected with a clamping seat; One end of the two telescopic rods is fixedly connected with a power plate; one surface of the power plate is movably connected with the card seat; one surface of the support frame is fixedly connected with an electric push rod; one end of the electric push rod is fixedly connected with a pressure sensor; one surface of the pressure sensor is fixedly connected with a spacer plate. Through the design of the crushing roller, the compression roller, the waste water drawer, the pressure sensor and the dewatering bucket, the present invention enables the trash can to perform the processes of pre-crushing, dewatering and compressing the garbage in sequence during the garbage disposal, so as to achieve the elimination of kitchen waste. The purpose of waste reduction treatment.

The invention discloses a semiconductor refrigeration device, which belongs to the technical field of semiconductor refrigeration. The invention includes a box body and a refrigeration assembly facing the interior of the box for cooling; the refrigeration assembly has at least one semiconductor refrigeration sheet, and the semiconductor refrigeration sheet A metal heat sink is attached to the cooling end of each metal heat sink; an airflow channel is formed on the surface of each metal heat sink, and the two ends of the metal heat sink are connected through a main pipe, and a circulation pump and a dehumidification mechanism are arranged on the main pipe. The air circulation in the air flow channel and the main pipeline air-dries and sucks the condensed water on the surface of the metal radiator. The invention has the beneficial effects of being able to avoid the accumulation of condensed water on the outer wall of the metal heat sink, reducing the risk of corrosion, high reliability, beneficial to prolonging the service life of the metal heat sink, and low maintenance and repair costs.

The invention discloses a heat insulation plate. The heat insulation plate comprises a cement plate decoration layer located on an outer layer, a cement plate base layer for being connected with a building wall and a sound insulation and heat insulation middle layer connected between the cement plate decoration layer and the cement plate base layer. The cement plate decoration layer is formed by, by weight, 95 parts of cement, 4 parts of lepiota brunneoincarnata powder and 1 part of cortex meliae powder. The heat insulation plate can effectively reduce the probability of egg reproduction of insects, moths and the like at the position of the heat insulation plate, and the worm breeding rate is greatly reduced; after the heat insulation plate with the lepiota brunneoincarnata powder added into the cement plate decoration layer is adopted, fewer birds can stop at the building top and the style design position, and the pollution to a building caused by bird excrement is effectively avoided. The sound insulation and heat insulation middle layer is extremely remarkable in sound insulation effect and good in heat insulation effect.

The invention discloses a magnetic oxygen-carbon tank integrated buffer device special for a train and relates to a magnetic oxygen-carbon tank integrated buffer device. At the present, buffer devices in two adjacent carriages of the train are complex in structure and simplex in function; meanwhile, passengers or article stacking in the carriages is dense, so that the quality of air in the carriages is poor, the purification cost is high, and ventilation and purification of the air in the carriages are difficult to ensure. A buffer is arranged in a coupler tail frame; one end of a train coupler is a hanging end, and the other end of the train coupler is a fixing end; the fixing end of the train coupler is hinged into the coupler tail frame through a coupler tail pin and connected with one end of the buffer through a rear follower plate, and the other end of the buffer is fixedly connected with the inner wall of the coupler tail frame through a front follower plate; a front ventilation piece is fixedly connected with the outer wall of the coupler tail frame, and the hanging end of the train coupler is detachably connected with the front end of a rear ventilation piece; and a magnetic oxygen-carbon tank machine is arranged in the rear carriage of the train and communicates with the rear end of the rear ventilation piece. The magnetic oxygen-carbon tank integrated buffer device special for the train is used for purification of the air in the carriages and buffering among the carriages.
