This utility model discloses a combined car cooling and fire extinguishing robot, including an active fire extinguishing mechanism and a passive fire extinguishing mechanism. The active fire extinguishing mechanism includes a chassis with walking mechanisms on both sides. A fire extinguishing pipe is installed inside the chassis, including a water inlet pipe with a first water inlet at one end and a water outlet at the other end. Several water inlet branch pipes are evenly connected to both sides of the water inlet pipe, and a spray pipe is connected to the end of each branch pipe. A first nozzle is installed at the outlet of the spray pipe. The passive fire extinguishing mechanism includes a fire extinguishing frame with a second water inlet. A connecting pipe connects the outlet and the second water inlet. Second nozzles are evenly arranged on the top of the fire extinguishing frame. This utility model has two fire extinguishing mechanisms, increasing the fire extinguishing range. Furthermore, the two fire extinguishing mechanisms are relatively low, allowing them to easily penetrate under the vehicle to precisely cool the battery and quickly and effectively control the fire.

The application discloses a kind of service concrete penetration type anti-freezing protective material and preparation method thereof, belong to concrete protection technical field.The composition of the protective material is: organic silicon modified penetration enhancement component 30~60 parts, nano-crystalline component 10~30 parts, microbial self-repairing component 5~20 parts, composite silane coupling agent 2~8 parts, penetration accelerator 1~5 parts, stabilizer 0.5~3 parts, defoaming agent 0.1~1 part, water 10~50 parts.The application constructs "hydrophobic barrier-crystallization densification-microbial self-repairing" triple synergistic protection system, solves the technical bottleneck that existing concrete protective material penetration depth is shallow, long-acting protection stability is poor, has no active crack repair capacity, construction is complicated, and on-site adaptability is poor.The application preparation process is simple, product performance is stable, cost-effective, can long-acting improve the frost resistance of concrete structure in severe cold area.

An electromagnetic flowmeter comprises a converter table body and a sensor, two pre-installation mechanisms symmetrically arranged in the sensor; the pre-installation mechanism comprises an insulating half-ring plate for surrounding the outside of a measuring tube, the inner wall of the insulating half-ring plate is provided with two groups of symmetric baffle assemblies for limiting the installation position of an electromagnetic coil and isolating the electromagnetic coil from the inner wall of the insulating half-ring plate; two docking half-rings for the electrodes outside the measuring tube to pass through are symmetrically arranged on the two sides of the insulating half-ring plate, one end of the docking half-ring is fixed to the inner wall of the insulating half-ring, and a half-arc notch in communication with the docking half-ring is formed in the insulating half-ring. The application is used to solve the problems that the vertical symmetry of the coil is difficult to guarantee during the assembly of the electromagnetic flowmeter and the insulating inner lining and the circuit are easily damaged by welding.

The present application provides a kind of low-calorie high dietary fiber fava bean powder and its preparation method, it relates to health-care product technical field.The present application fava bean powder includes: fava bean raw material powder, traditional Chinese medicine extract, dietary fiber, gamma-cyclodextrin, resistant dextrin, thickening agent, flavoring agent;Traditional Chinese medicine extract is composed of dendrobium extract, rhodiola extract and lotus leaf extract.Fresh fava bean whole plant is freeze-dried, pulverized to prepare fava bean raw material powder;Dendrobium extract is prepared by long bifidobacterium and pentose pediococcus compound fermentation, rhodiola extract is prepared by ultrasonic-assisted alcohol extraction combined with ultrafiltration purification, and lotus leaf extract is prepared by flash extraction combined with macroporous resin purification.The present application effectively protects the heat-sensitive active ingredients in fava bean and traditional Chinese medicine by adding resistant dextrin and gamma-cyclodextrin double embedding technology, improves the pungent bitter taste, and improves the instant performance.The present application fava bean powder has the effects of reducing blood sugar, reducing blood lipids and assisting in weight loss, and can be used for preparing related health-care products.
