The invention discloses intelligent inspection robot equipment for underground chamber detection and a detection method.The intelligent inspection robot equipment comprises a general detection robot and a detailed detection robot, the general detection robot is used for recognizing defects and obtaining the positions of the defects, that is, the defects are rapidly positioned, and preliminary judgment and screening are conducted on the defects; according to the detailed detection robot, the multi-detection cooperation module is adopted to reach the defect position / nearby to judge whether gas leakage exists in the defect area or not, and whether gas leakage exists in the defect position or not is detected more meticulously and accurately. According to the method, a multi-robot cooperation mode of a child-mother system composed of the general measurement robot and the detailed measurement robot is adopted, rough measurement and detailed measurement are combined, the detection efficiency is greatly improved, patrol inspection, defect analysis and evaluation can be conducted on the compressed air energy storage underground chamber without shutdown, and safe and healthy operation of the underground chamber is effectively guaranteed.

The invention relates to a portable standard gas supply device and method. The portable standard gas supply device comprises a gas source, a pressure reducing valve, a high-pressure stop valve, a pressure stabilizing chamber, a micrometering valve, a gas distribution chamber, an absolute pressure sensor, a first capacitance film gauge, a second capacitance film gauge, a Pirani vacuum gauge, a first high-vacuum angle valve, a second high-vacuum angle valve and a vacuumizing system. According to the portable standard gas supply device and method, through reasonable design, the device and the pipeline have the functions of heating, gas extraction and purification, replacement, portability and the like, the gas purity is guaranteed from the source, pollution of residual gas or organic matter is reduced, measurement errors caused by unreasonable design are reduced, and the measurement accuracy is improved. The accuracy of the prepared standard gas pressure and components is ensured to the maximum extent; the gas distribution precision is improved, the uncertainty of the gas distribution concentration is reduced, the requirement of field dynamic gas distribution can be met, and the method is simple, feasible and easy to operate.

The present invention discloses a multifunctional steaming grid and a steaming grid system, the multifunctional steaming grid comprising a steaming grid body and a lower annular rubber pad; the steaming grid body and the lower annular rubber pad are connected up and down, and the steaming grid body is provided with at least one through-hole; the outer contour of the lower annular rubber pad is adapted to the outer contour of the steaming grid body in the radial direction and the circumferential direction. The present invention can meet the needs of using the same steaming grid for electric rice cookers or other pots of various specifications, ensure the sealing performance of the steaming grid and the electric rice cooker or other pot, avoid the phenomenon of water vapor leakage, improve the working efficiency of steaming food, ensure the taste of dishes, and improve practicality.

This utility model relates to the field of tire technology, and more particularly to an outer protective structure for an all-steel radial tire. It includes a bead wire, a cord layer sleeved around the bead wire, an airtight layer bonded inside the cord layer, a steel wire layer bonded to the outer wall of the cord layer, a radial main body at the connection between the steel wire layer and the cord layer, a belt layer bonded to the outer wall of the steel wire layer, a tire shoulder bonded to the outer wall of the belt layer, a tire crown bonded to the outer wall of the tire shoulder, a protective sleeve on the inner wall of the tire crown, and tread blocks on the outer wall of the tire crown. This utility model features a mesh-like protective sleeve, which improves the structural strength of the tire crown and prevents punctures that could cause tire deflation. Two sets of tread blocks provide protection for the tire crown, and "V"-shaped grooves improve the tire's grip and allow for timely drainage of accumulated water.

The utility model discloses a built-in pump, which relates to the technical field of built-in pumps and comprises a sealed cabin body, a wedge-shaped fairing is arranged on one side of the sealed cabin body, a silica gel ring fixing baffle is arranged on the outer side of the wedge-shaped fairing, and a silica gel ring is arranged between the silica gel ring fixing baffle and the wedge-shaped fairing. According to the utility model, a unique ventilation structure (converter) is used, so that the same air port can be used for inflating and deflating, the trouble that the whole air pump needs to be taken out and the air port of the air pump needs to be replaced to be connected with the air port of an inflatable bed when a conventional air pump product is used for switching between inflating and deflating can be avoided, and the air port of the air pump can be changed to be connected with the air port of the inflatable bed; the design of the wedge-shaped fairing is adopted at the position of the air port connected with the air bed, the air pressure and the air flow at the position can be guaranteed, and the situation that the air port is directly sealed through a right-angle baffle like the similar competitive products, and consequently the air pressure and the air flow are reduced, and noise is increased is avoided.
