The utility model discloses an ecological vegetation restoration planting frame, which belongs to the technical field of ecological vegetation planting and comprises a frame body, a soil fixing net and a pipeline group. Wherein the frame body is provided with an upward opening, the non-opening surface of the frame body is provided with a channel for water and soil to pass through, the soil fixing net covers the channel, the pipeline group is buried in the frame body, the pipeline group comprises a main pipeline and an auxiliary pipeline, the main pipeline and the auxiliary pipeline are communicated with each other, and a plurality of uniformly distributed vent holes are formed in the main pipeline and the auxiliary pipeline. The utility model has the advantages that the soil fixation net can intercept silt to form preliminary filtration; the pipeline group forms an air gallery positioned in the frame body, so that root systems of plants planted in the planting frame can obtain good ventilation; the two are combined to realize efficient balance of water and soil conservation and root system ventilation.

The utility model relates to the technical field of experimental animal box type cage cleaning machines, and discloses an experimental animal box type cage cleaning machine which comprises a cleaning box, a water tank is fixedly connected to the outer side of the cleaning box, and a water outlet of the water tank is fixedly connected with a first water pump through a water pipe. A first telescopic pipe is fixedly connected to a water outlet of the first water pump, a first mounting frame is slidably connected to the top wall of the interior of the cleaning box, the end, away from the first water pump, of the first telescopic pipe is fixedly connected with the first mounting frame, and a first cleaning brush is rotatably connected to the interior of the first mounting frame; the outer side of the first mounting frame is fixedly connected with a first motor, and an output shaft of the first motor is fixedly connected with the first cleaning brush. The experimental animal box type cage cleaning machine has the advantages that the outer side of an animal is brushed and washed through a cleaning brush, the animal cannot be flushed violently, water, a cleaning agent and a disinfectant are prevented from entering the mouth and the nose of the animal, and normal breathing of the animal during cleaning is guaranteed.

This utility model relates to the field of emergency treatment technology and discloses a protective device for head and face rinsing, including an elastic fixing strap, a connecting ring provided on the inner side of the elastic fixing strap, a first Velcro fastener connected to one end of the elastic fixing strap, a side baffle fixedly connected to one side of the elastic fixing strap, and a connecting rope fixedly connected to one side of the elastic fixing strap. This protective device for head and face rinsing, through the cooperative arrangement of the elastic fixing strap, connecting ring, and first Velcro, allows the elastic fixing strap to be pulled within the connecting ring during use, causing it to conform to the patient's face. This, in turn, secures the first Velcro fastener at one end of the elastic fixing strap to both sides, thus facilitating both conformation to the patient's face and easy fixation. The cooperative arrangement of the side baffle and rear baffle allows the rear baffle to block the water flow from the back of the head during use, while the side baffles further prevent water flow from the sides, thus providing auxiliary water flow blocking.

The utility model discloses a multifunctional fire-proof suit head cover which comprises a shell, an observation window is arranged on the shell, two rotating grooves are formed in the outer wall of the shell, rotating discs are arranged in the rotating grooves, outer extrusion grooves are formed in the rotating discs, outer positioning blocks are arranged in the outer extrusion grooves through outer elastic mechanisms, outer positioning holes are formed in the outer wall of the shell, and the outer positioning holes are communicated with the rotating discs. Two mounting holes are formed in the rotating disc, air holes corresponding to the mounting holes are formed in the inner wall of the shell, and mounting pipes are arranged in the mounting holes through sealing mechanisms. Two protective nets are arranged in each mounting groove, and when one protective net is blocked, the other protective net can be quickly switched to work. By means of the design, the reliability of the hood in a complex fire environment is greatly improved, it is ensured that when the protective net is blocked, good air inlet and outlet functions can still be continuously kept, normal breathing of a user is ensured, and smooth rescue work is not affected.
