5results about How to "Good emergency effect" patented technology

The application provides a lithium battery step utilization energy storage device, and relates to the field of energy storage equipment.The lithium battery step utilization energy storage device comprises a base, a lithium battery cabinet arranged on the base, and a solar panel arranged above the lithium battery cabinet, and further comprises a rainwater collecting and heat dissipation system.The rainwater collecting and heat dissipation system comprises a rainwater collecting tank, a water-cooling heat dissipation assembly, and a driving assembly.The rainwater collecting tank is arranged below the solar panel, the top of the rainwater collecting tank is connected with the solar panel to collect rainwater, and the rainwater collecting tank is rotatably arranged.The water-cooling heat dissipation assembly is arranged on the lithium battery cabinet.When the temperature of the lithium battery abnormally rises, the system can automatically start within tens of seconds, and the stored rainwater is rapidly poured into the heat dissipation assembly, the water has a large heat capacity, and the heat dissipation assembly can effectively and rapidly absorb heat, so that the temperature rise of the lithium battery is effectively and rapidly inhibited, the chain reaction of thermal runaway is broken, and valuable time is gained for fault treatment.

The present invention relates to the technical field of Bluetooth headsets, and discloses an emergency type Bluetooth headset that can be powered by an additional battery, comprising a housing, a swing door movably connected to the bottom of the housing, a sliding rod slidably connected to the inside of the swing door, a buffer spring fixedly connected to the side of the sliding rod close to the swing door, a connecting mechanism sleeved to the side of the sliding rod away from the swing door, a top rod welded to the top of the battery assembly, and a touch rod movably connected to the top of the top rod. The emergency type Bluetooth headset that can be powered by an additional battery can be raised by pressing the connecting mechanism, the connecting mechanism drives the sliding rod to swing, the sliding rod drives the swing door to swing upward, and at the same time the sliding rod slides relative to the swing door, the connecting mechanism drives the battery assembly to rise, the battery assembly drives the top rod to rise, the top rod drives the touch rod to swing, and then the touch rod and the moving contact are used in coordination, thereby achieving the effect of emergency power supply with an additional battery and good emergency effect.

A multi-mode double-delay faucet comprises a rotating handle, a rotating shaft linked with the rotating handle, a movable ceramic piece and a fixed ceramic piece, a water outlet is formed in the wall of a valve element shell, and the rotating shaft extends into the valve element shell to drive the movable ceramic piece and the fixed ceramic piece to rotate relatively so as to achieve connection or disconnection of a water path. A middle hole is formed in the middle of a flange plate in an inner cavity of the rotating handle and used for allowing the rotating shaft to penetrate through. A pull rod moves on a flange plate body along with rotation of the rotating handle. One end of a circular torsion spring is a movable end which is arranged to be an externally-expanded arc-shaped end and is detachably hooked on the baffle table of the flange plate, and the other end of the circular torsion spring is arranged in the spring limiting buckle to realize tension deformation; the external expansion arc-shaped end is positioned on the moving track of the pull rod; the pull rod rotates leftwards to drive the torsion spring to deform, and delayed closing is achieved in the reset process. The pull rod rotates rightwards to break away from the torsion spring, so that the faucet is manually closed; the product provided by the invention has double modes of time delay and normally open (manual switch), so that the product has a wider application scene.

The invention provides a double-layer structure drainage ditch for ecological restoration, and relates to the technical field of water conservancy projects. The drainage groove is of a concave structure, road plates are laid on the top of the drainage groove in a linear array mode, and first filtering holes are formed in each road plate in an array mode. Multi-stage filtration can be carried out, impurities are effectively prevented from entering the drainage tank, and smooth drainage is guaranteed; structural design is optimized, the filtering efficiency is improved through the filtering plate of the V-shaped structure, impurities automatically slide off through the inclined design of the filtering plate, filtering holes are prevented from being blocked, when the filtering plate is cleaned and the filtering plate of the V-shaped structure is taken out, the impurities on the filtering plate cannot fall into a drainage groove, and cleaning is thorough; the top of the filter plate is in contact with the bottom end surface of the channel plate, so that the channel plate can be supported by the filter plate in the use process, the channel plate is prevented from being broken due to overlarge stress, and the subsequent maintenance cost is reduced.

The utility model discloses a three -way ball valve, it includes valve body, the top fixedly connected with first fixed plate of valve body, the top of first fixed plate is established with through -hole, the circumference inner wall of through -hole is connected with the rotating rod through screw thread, the circumference outer wall fixedly connected with butterfly valve of rotating rod, the circumference outer wall swing joint of rotating rod has the roof, the bottom fixedly connected with side baffle of roof, the side of side baffle is fixedly connected with side edge arc plate. This kind of three -way ball valve, through the circumference outer wall fixedly connected with butterfly valve of rotating rod, through the rotation main staff drive butterfly valve, make it can rotate, can manually select the direction of flow under the condition of power failure, still can normal operation under the condition of power failure, and cooperate side baffle with the side arc plate still can protect valve body, secondly, the inside fixedly connected with filter screen of connecting pipe, and the bottom fixedly connected with threaded pipe for connecting of connecting pipe, when filter screen blockage damage can conveniently change.
