The utility model belongs to the field of underground self-rescue facilities, and particularly relates to a water supply rescue and compressed air self-rescue combined device. Comprising a box body with an opening in the side face, and a water supply rescue device and a compressed air self-rescue device are arranged in the box body; a water supply self-rescue unit of the water supply rescue device and a compressed air self-rescue unit of the compressed air self-rescue device are distributed in a row within the opening range of the box body; according to the water supply rescue and compressed air self-rescue combined device, a water supply rescue device and a compressed air self-rescue device which are originally independent are integrated in the same box body, and the problems that a traditional split device is dispersedly installed and inconvenient to operate, and personnel need to switch the position back and forth are thoroughly solved; the interfaces (the water supply branch pipes and the compressed air masks) of the two self-rescue units are distributed side by side in the opening range of the box body, so that a user can quickly and conveniently use the water supply and compressed air self-rescue functions simultaneously or alternately at the same position and facing the same operation surface, and the cooperative operation efficiency in an emergency is greatly improved.

The utility model relates to the technical field of sand washing devices, and discloses an efficient sand washing device which comprises a cleaning box, a water spraying head is arranged at the top of the cleaning box, an impeller is arranged in the cleaning box, one end of the impeller is fixedly connected with a first motor, and supporting legs are fixedly connected to the bottom of the cleaning box. A water tank is arranged at the bottom of the cleaning box, one end of the water tank is fixedly connected with a second conveying pipe, one end of the second conveying pipe is fixedly connected with the cleaning box, a stirring mechanism is arranged at the top of the water tank, the stirring mechanism comprises a second motor, and sewage and a flocculating agent are evenly mixed through rotation of a clamping plate rod. The stirring rod is provided with the strip-shaped hole, so that the resistance borne by the stirring rod in the rotating process can be reduced, meanwhile, sewage penetrates through the strip-shaped hole, so that surrounding sewage can be subjected to stronger shearing force and impact force, a flocculating agent can be fully mixed and reacted with the sewage, and impurities can be precipitated.

The utility model discloses a pet water dispenser, including host computer, be used for external water purifying water purifying tank, be used for sewage disposal sewage tank, drinking water tray, drive mechanism, circulating water supply mechanism, filter mechanism and cleaning mechanism, the drinking water tray sets up in the sewage tank top, the drinking water tray with drive mechanism connects, drive mechanism is used for driving drinking water tray rotates along horizontal axis, to pour the water in drinking water tray into sewage tank, circulating water supply mechanism is used for the water purifying tank in with drinking water tray is delivered, filter mechanism installs in sewage tank is used for filtering the sewage that drinking water tray pours out, the cleaning mechanism is used for removing the dirt on the surface of drinking water tray, the host computer is equipped with with drive mechanism, circulating water supply mechanism, filter mechanism and cleaning mechanism electric connection's controller. The problem such as need artificial adding water source, water source is not clean etc. that traditional pet water dispenser exists has been solved.

The utility model provides a channel water quality filtering and monitoring device which comprises a channel, a lifting filtering device is arranged on the channel, the filtering device comprises a first filtering plate and a second filtering plate, a dredging plate is arranged between the first filtering plate and the second filtering plate, two ends of the dredging plate are respectively provided with two screw rods, and two pushing frames are arranged on one side of the first filtering plate. And the pushing frame is connected with the screw rod. When the whole device works, the winch is driven to be wound, so that the filtering device slides to the bottom of the channel along the vertical sliding groove of the channel. A flow sensor is mounted on the water pipe on the second filter plate, the filter aperture of the first filter plate is larger than that of the second filter plate, the first filter plate is mainly used for intercepting large-size floating garbage, the second filter plate is used for further filtering fine particle impurities such as silt, and the two filter screens form a graded filter structure, so that the filter effect is improved; it is ensured that water entering the subsequent part of the channel is clean.

The invention discloses a building roof rainwater collection and reuse system based on a sponge city, and relates to the technical field of rainwater collection and treatment, the building roof rainwater collection and reuse system comprises a main body, the outer surface of the main body is clamped with a support column, the upper end of the main body is fixedly provided with a butt joint cylinder, and the inner wall of the main body is fixedly provided with a support rod; according to the building roof rainwater collecting and recycling system based on the sponge city, impurities accumulated on the filtering surface can be automatically cleaned in real time through the protection assembly, water flow interruption or overflow caused by blockage is effectively prevented, and it is ensured that the rainwater collecting process is smooth and efficient; the reliability and adaptability of the system under various rainfall conditions are improved, meanwhile, impurities accumulated on the surface can be effectively cleaned before the water enters the storage box, the burden of follow-up water treatment is reduced, and therefore the quality of collected water is improved.
