The invention discloses a school bus fall-into-water safety escape system. An anti-sinking device and an escape device are arranged in a school bus body. The anti-sinking device comprises inflatable anti-sinking air bags arranged on the outer portion of the bus body, the escape device is an escape door which is installed on the tail portion of the bus body and can be separated from the bus body, inflatable escape air bags are arranged on the periphery of the escape door, and therefore the escape door separated from the bus body and inflated serves as an escape inflatable boat capable of carrying people; and a control device is arranged and used for controlling the anti-sinking device and the escape device to work in order, the state of the bus body is judged through a three-axis gyroscope,when it is confirmed that the state of the bus body is stable, the escape door is controlled to be separated from the bus body, the escape air bags are inflated, and personnel in a school bus are quickly evacuated through the escape inflatable boat. A safety guarantee provided in a fall-into-water accident possibly happening to the school bus can be effectively improved, and personnel are prevented from being harmed by a near-drowning secondary accident.

The invention discloses a swimming pool drowning prevention alarm device. The device comprises several laser sensors installed in a swimming pool deepwater area and an alarm system installed in a lifeguard waiting area. A detection path of each laser sensor is parallel to a swimming pool bottom. The alarm system comprises a control unit and an alarm apparatus arranged in the waiting area. The laser sensors, the control unit and the alarm apparatus are electrically connected. Through arranging the several laser sensors in the swimming pool and transmitting detection results of the laser sensors to the waiting area, when a person is near-drowning, a lifeguard can acquire information timely and rescue the drowning person timely. In addition, through a display screen design, the detection results of the laser sensors are displayed through a display screen; when the laser sensors detect abnormity, through watching the display screen, the lifeguard can timely and accurately position an abnormal place and carry out rescue; the positioning is accurate and efficiency is high.

The invention discloses a near-drowning life saving bracelet which comprises a folded belt-shaped airbag body. The airbag body comprises an open end and a sealed end, and the sealed end is detachablyfixed to the airbag body. The near-drowning life saving bracelet further comprises a one-way medium circulating mechanism, a rotating shaft folding and unfolding mechanism and a gas generating substance, wherein one end of the one-way medium circulating mechanism clamps the open end of the airbag body, and external fluid media flow into the open end of the airbag body in one way from the one-way medium circulating mechanism; the rotating shaft folding and unfolding mechanism is movably arranged in the airbag body and is unfolded in the airbag body under the action of external force; and the gas generating substance is arranged in the rotating shaft folding and unfolding mechanism and encounters with the fluid media flowing into the airbag body to generate gas which expands the airbag bodywhen the rotating shaft folding and unfolding mechanism is unfolded. According to the near-drowning life saving bracelet, the problems that an existing life saving bracelet is not convenient to use due to limit of the size and weight, and the potential safety hazard of gas cylinder explosion exists are solved.

The invention provides a land safety sightseeing pleasure boat and belongs to the field of land rowing. Universal running wheels are installed at the bottom of a boat body, a brake hole is formed in the bottom of the boat body, a brake pressing handle penetrates through a return spring and the brake hole and then stretches below a boat bottom to be connected with a ground contactor, a surrounding edge is fixed to the periphery of the bottom, provided with the universal running wheels and the ground contactor, of the boat body, bearing installing rings are fixed to the upper ends of paddle supports on boat boards fixed to the two sides of the boat body, arbitrary rotating bearings are installed in inner holes of the bearing installing rings, and land paddles are fixed to the arbitrary rotating bearings at the upper ends of the paddle supports in the mode that bearing rods penetrate through inner rotating shaft sleeves of the arbitrary rotating bearings. The land safety sightseeing pleasure boat is simple in structure and convenient to manufacture and use, and the rowing mode is identical with the rowing mode in water; rowing is safe during relaxation, entertainment, riding instead of walking, sightseeing and physical exercise on land, and the phenomena of boat turning and near-drowning are avoided; the land safety sightseeing pleasure boat is suitable for relaxation, entertainment, riding instead of walking, sightseeing and physical exercise of people of all ages.

The embodiment of the invention, which relates to the technical field of the wearable equipment, discloses a wearable-equipment near-drowning monitoring method and apparatus, and wearable equipment. The method comprises: an environment where wearable equipment is located is detected and thus a detection result is obtained; when the detection result indicates that the environment is a wet environment, an underwater pressure intensity sensing function of the wearable equipment is started, the pressure intensity of the wearable equipment in the wet environment is detected based on the underwater pressure intensity sensing function; on the basis of the pressure intensity, an underwater penetration value of the wearable equipment in the wet environment is determined; when the underwater penetration value is larger than or equal to a preset depth threshold value, an early warning signal corresponding to the underwater penetration value is sent to at least one early-warning platform arranged in advance, wherein different underwater penetration values correspond to different early warning signals. Therefore, near-drowning monitoring on a user wearing wearable equipment can be realized by using the wearable equipment.

The invention discloses a land-competition safe dragon boat, and belongs to the field of land dragon boats. Universal running wheels are installed at the bottom of a boat body of the land-competition safe dragon boat, a braking hole is formed in the bottom of the boat body, a braking pressing handle penetrates through a return spring and the braking hole, extends to the portion below the bottom of the boat and is connected with a ground contactor, and surrounding edges are fixed to the portions, where the universal running wheels and the ground contactor are installed, of the periphery of the bottom of the boat body; boating persons apply force with the bodies to handheld paddles to drive the boat body to advance. The land-competition safe dragon boat is simple in structure and convenient to manufacture and use, and the boating mode and the boating competition mode are the same as the boating mode and the boating competition mode in water; the land-competition safe dragon boat is high in practicability, boat-turning near-drowning events caused by dragon boat competition in rivers are avoided, and viewing persons can view the dragon boat competition in a close range.
