The invention provides an efficient combustor and a low-load stable combustion boiler, and relates to the field of thermal power generation, the efficient combustor comprises a mounting cylinder, a connecting disc is fixedly arranged at the rear end of the interior of the mounting cylinder, a flow equalizing assembly is arranged in the mounting cylinder, a rotational flow assembly is arranged at the front end of the flow equalizing assembly, and a flow stabilizing assembly is arranged at the front end of the rotational flow assembly; a connecting assembly is arranged at the rear end of the connecting disc, a conveying assembly is arranged in the connecting assembly, an air supply assembly is arranged behind the connecting assembly, and a combustion-supporting assembly is arranged above the connecting assembly. By means of the flow equalizing assembly, resistance is reduced at high air pressure through the flow equalizing assembly, and energy consumption of the draught fan is reduced; the flow speed is increased at low wind pressure, so that airflow distribution and flow speed are uniform, flame drift caused by non-uniform flow speed at low load is avoided, airflow is ensured to enter a combustion area at the most ideal flow speed, and the combustion stability is improved.

The present application relates to the technical field of vehicle passenger room air channel, in particular to a special air duct for vehicle air conditioner and a vehicle, the special air duct for vehicle air conditioner is a flexible body, used for being arranged in the air conditioner air supply duct, the special air duct has a special air inlet and a special air outlet, the special air inlet is connected with the air conditioner air outlet on the inner wall of the air conditioner air supply duct, and the special air outlet is connected with the air supply duct air outlet on the inner wall of the air conditioner air supply duct, so that the air treated by the air conditioner is conveyed into the vehicle compartment through the special air duct, air supply is carried out by using the flexible special air duct, the space in the air conditioner air supply duct can be adapted, the cross section area mutation is reduced, the influence of the existing parts in the air conditioner air supply duct on the airflow can be avoided, the airflow kinetic energy can be effectively reduced due to the contact between the airflow and the parts, and the uniformity of the air outlet of each air supply duct can be ensured.

The utility model discloses a combined sampling device for an oil gas and uranium mine co-generation mining area, which comprises a drilling cylinder, a sampling device, a sampling device and a sampling device, wherein the bottom of the drilling cylinder is provided with an opening, and a rotating pipe is embedded and fixed at the top of the drilling cylinder; an opening is formed in the front side of the box-shaped seat, a cover plate is fixedly connected to the front side of the box-shaped seat through four screws, the box-shaped seat rotationally sleeves the top of the outer side of the rotating pipe, and handle rods are fixedly connected to the two sides of the box-shaped seat. According to the utility model, a series of structures are arranged, so that unblocking sampling and blocking after sampling are facilitated after moving downwards to a required sampling depth, the phenomenon that multiple layers of geological samples are mixed together during drilling sampling can be effectively avoided, the influence on the subsequent detection and analysis accuracy is reduced, the sampling accuracy effect is improved, and the sampling efficiency is improved. The phenomenon that hydrocarbon fluid flows down when the hydrocarbon fluid is moved out upwards after sampling can be avoided, the device is conveniently and stably suitable for integrated combined sampling work of an oil gas and uranium mine co-generation mining area, and the applicability and the sampling stability are improved.

This invention discloses a soil retaining device for soil and water conservation. Its structure includes an inclined plate, movable limiting components, a mounting frame, a base, a blocking device, and reinforcing plates. In use, the device is stably installed at its corresponding position by two inclined plates symmetrically connected to the left and right sides of the base to form an isosceles trapezoidal structure. This effectively buffers the soil. Two reinforcing plates are installed on the left and right sides of the base in conjunction with the mounting frame. The blocking device is installed parallel to the base with the reinforcement plates and mounting frame. Movable limiting components are installed on the left and right sides of the reinforcing plates to connect with the blocking device. These components control the movement limit of the blocking device, preventing excessive movement and failure to return to its original position, thus enabling the blocking device to effectively retain soil.

The utility model discloses a kind of knitted fabric steam setting devices, including rack and symmetrically installed on rack for conveying fabric conveying belt, rack is fixedly connected with mounting bracket, and mounting bracket and conveying belt form steam cavity between, further including symmetrically installed on mounting bracket's stand, symmetrically and rotationally set up guide for transmission fabric on stand.The utility model can complete pre-heating softening in the process of fabric conveying by setting preheating plate inside conveying belt, effectively eliminate knitted fabric weaving residual internal stress;While matching swing-adjustable first roller and slidable second roller, using gear and meshing tooth meshing transmission and first hydraulic rod tension control structure, can adapt to different width different knitted fabric of gram weight, whole process keeps fabric conveying tension balanced, effectively prevent fabric walking deviation, local relaxation, excessive stretching and surface wrinkle deformation, greatly improve fabric conveying stability and processing adaptation range.

The present application relates to a kind of precision guiding nest-preventing device and nest-preventing method integrated in sewing machine needle plate, the device is provided with fixed knife and movable knife on the lower surface of sewing machine large needle plate, the movable knife includes hooking part, dividing part, wire container groove and wire hole, cooperates with presser foot, blowing and suction pipe and connecting rod type driving mechanism, through the timing design of "stitching thread - guiding presser - stabilizing thread loop - cutting cleaning - resetting", realizes the precise guidance of thread end, cutting and cleaning.The device can reuse the built-in power of sewing machine, has compact structure and strong adaptability, can completely avoid the winding of starting thread, improve the quality and operation continuity of sewing product, and is suitable for all kinds of sewing machines such as lockstitch machine and pattern machine.
