This utility model relates to the field of urban greening technology, and more particularly to a roadside green landscape belt for urban planning. The technical solution includes: a water storage tank is provided below the planting trough; a baffle is rotatably installed at the top of the planting trough via a hinge; the planting trough and the water storage tank are connected by a perforated plate, and fiber absorbent rods are inserted into the perforated plate. The fiber absorbent rods draw water from the water storage tank into the planting trough through capillary action, providing moisture for the plants in the planting trough; troughs are formed at both ends of the planting trough, and these troughs are connected to the water storage tank. A float is provided in the water storage tank, and a push rod is provided on the float. The push rod is movably connected to the baffle via a rotating seat. When the float moves up and down within the water storage tank, the float pushes the baffle to flip open via the push rod. This utility model achieves automatic opening and closing of the baffle according to the water level, precisely controlling the environment, creating suitable conditions for plant growth, and improving the efficiency of the green landscape belt.

This utility model belongs to the field of plant cultivation technology, specifically disclosing a transparent device for hydroponic plant cultivation using a solid substrate. It includes a cultivation container with a partition dividing it into an upper and lower cultivation section. The upper cultivation section contains nutrient soil, and the lower cultivation section contains nutrient water. The partition has multiple fine holes and perforations, with cotton fibers threaded through the perforations. The ends of the cotton fibers extend to the upper and lower cultivation sections respectively. The sidewall of the lower cultivation section has through holes. This utility model separates the nutrient soil and nutrient water layers using the partition and uses the through holes to drain excess water while simultaneously creating an air barrier. During plant growth, the roots extend from the fine holes in the partition into the nutrient water in the lower cultivation section, passing through the air barrier layer. This ensures the roots receive sufficient oxygen, preventing root rot. The through holes also facilitate observation of root growth, ensuring healthy plant growth.

The utility model discloses a jet atomization type heater, which belongs to the technical field of heaters, and comprises a shell mechanism and a heat conduction mechanism, the shell mechanism is in threaded connection with an air outlet mechanism, the heat conduction mechanism is further fixed in the shell mechanism, a jet mechanism is further fixed on the shell mechanism, and the jet atomization type heater is arranged in the shell mechanism. And an ignition mechanism is also fixed on the shell mechanism. Through the arrangement of the shell mechanism, the gas outlet mechanism and the heat conduction mechanism, the residence time of hot gas in the device is effectively prolonged, and the heat conduction area of the device is increased, so that heat conduction is more sufficient, the temperature of waste gas is reduced, and heat waste is reduced; the air inlet of the combustion chamber is more powerful and stable, so that sufficient oxygen in the combustion chamber is guaranteed, fuel waste caused by insufficient combustion is reduced, the combustion stability is guaranteed, and the safety of the device is improved.

The invention belongs to the technical field of medical instruments, and particularly relates to a capsule type enteral nutrition tube band and a use method. Comprising a plurality of soluble capsules, the soluble capsules are connected in series through a nutrient canal belt, the nutrient canal belt is arranged in the soluble capsules in a curled and compressed mode, an X-ray-impermeable marker is arranged on the soluble capsule at the head end, liquid is contained in the soluble capsule at the head end, and the soluble capsule at the tail end is connected with an in-vitro port through the nutrient canal belt. According to the capsule type enteral nutrition tube belt, the capsule can be easily fed into the gastrointestinal tract only by being swallowed by a patient through drinking water. In the swallowing process, the capsule can smoothly pass through the esophagus along with water flow, enters the stomach and then reaches the intestinal tract. In the whole process, invasive operation does not need to be conducted on the nasal cavity or the oral cavity, pain caused by nasal cavity intubation is completely avoided, more comfortable and convenient intubation experience is provided for a patient, and the compliance of the patient during enteral nutrition support treatment is greatly improved.
