Underwater LED light

An underwater light, e.g., for a pool or spa, includes an ordinarily watertight housing, an outer compartment within the housing and floodable by water flowing therein in the event the housing is no longer watertight, a current shield within the outer compartment and at least partially defining an inner compartment within the outer compartment, a light emitter within the inner compartment, a passageway communicating between the inner and outer compartments such that outer compartment flood water can enter the inner compartment and contact the light emitter, and a conductor. The conductor is positioned so as to collect stray electrical current conducted from the inner compartment by water within the passageway, thereby reducing the risk of shock presented by such stray electrical current. The underwater light is installable within a wet niche, and includes a transformer housed in a separate compartment that extends into the wet niche for thorough cooling thereof.

ActiveCN104460343AIncrease the number ofAvoid the problem of interpolation distortionSimulator controlFlood waterWater level
The invention discloses a riverway flood inundation simulation method based on water level monitoring data. According to the method based on the scattered water level monitoring data collected along a riverway, firstly, piecewise linear interpolation is carried out on a center line of the riverway, and water level values of all places along the center line of the riverway are obtained; secondly, on a riverway DEM, the flood water level of each DEM box is worked out according to the nearest neighbor interpolation; lastly, the actual inundation range and the actual inundation water depth distribution of riverway flood are calculated according to the seed region growing method in the riverway. According to the riverway flood inundation simulation method, the natural form change of riverway winding up and down is fully taken into consideration, interpolation is carried out on the value of the riverway water level between water level monitoring stations according to distance parameters, and the interpolation water level distortion problem can be effectively avoided. Meanwhile, the riverway flood inundation simulation method can effectively solve the problem that due to the fact that the number of the flood water level monitoring stations distributed on the riverway is too small, and water level monitoring data sample points are insufficient, a conventional flood water level space interpolation method based on overall areas is hard to apply.

The water barrier is comprised of a number of interconnected modules, that contain expansive material (such as polymer powder). Each module has inlets that allow rising water to enter the interior volume of the module so that it inflates from a flattened configuration to a four sided shape. The shape is wedge shaped and the modules are alternated so that the narrow end of the module is toward the rising water on one module and the wide end is next to the rising water on the adjacent module, so that pressure from the rising water is transferred to adjacent modules from module to module and ultimately to an anchoring system.

Prefabricated levee apparatus and system

A levee apparatus and system for impeding and controlling the flow of fluids, primarily the flow of water as experienced in a flood or storm surge consisting of a light weight concrete structure with reinforcing steel rebar depending on the application. It is constructed from prefabricated sections with the tongue and groove ends designed to fit together which, when used in conjunction with a rubber gasket, will produce a water tight seal. The structure would be hollow with an opening along the unprotected face to provide a location for the surge water to enter. The structure would have flap-gates on the protected side and on the unprotected side. This would allow flood waters from the protected side to push open the flap-gate and exit the protected side based on the pressure equalization of the flood waters. Once inside the structure any water would then drain from the structure through the flap-gate on the unprotected side when the surge water diminishes. The structure could be placed simply on top of the existing soils or anchored in place to prevent potential changes in alignment. Two main modifications to this design include utilization of a rubberized base which would allow the top portion of the structure to rise into position, and the adjustment of the flap-gate position to change the use of the structure from solely a flood protection system to a retention control system.

Underground battery container system

A rechargeable battery, such as a 12 Volt battery that is recharged by a solar panel, is placed into a container system that includes an enclosure, having a top portion that is open and a bottom portion that is open, that is substantially buried underground. A sleeve, having a bottom portion that is open and a top portion that is closed, is lowered into the enclosure such that air is trapped inside the top portion of the sleeve when water collects against the enclosure. The trapped air prevents flood water from rising high enough to contact terminals of the battery. When flood conditions subside, the water drains out the bottom portion of the container system into the ground. Additionally, a ridge around the bottom of the sleeve makes it easier to insert the sleeve into the enclosure because the ridge slides over the dirt and debris, but the ridge scrapes and removes unwanted dirt and debris from the enclosure whenever the sleeve is removed to access the battery. A battery platform may be used to raise a battery higher into the sleeve. The entire container system can be completely buried underground, but access to a battery in the container only requires that the dirt covering the top most part of container be removed, and then the sleeve is simply lifted out of the enclosure without having to dig around the enclosure.

Flood Temporary Relief System and Method

A temporary flood relief system for use in the presence of water and impending flooding includes a first container for a prepolymer, a second container for a catalyst, a third container for mixing the prepolymer and catalyst, and a water source connected to the third container. The water source applies the prepolymer and catalyst of the third container to a wall and slab of a building or similar surface that is porous to flood water in absence of restrictive barrier. The system also includes an applicator connected to the third container, and a pressure source connected to the applicator for dispersing the prepolymer and catalyst, as mixed, together with water, using the applicator. The prepolymer and catalyst, on application to the surface in presence of water, foams, expands, and hardens to a pliable solid polymer impermeable to water. The polymer adheres to the surface of application. The flood relief system is unitized as a consumer useable article, containing the prepolymer and catalyst, and application to the surface is possible without human contact of the prepolymer and catalyst. The polymer is easily removed from adherence to the surface after flooding subsides, such as by pressure wash with water.

Systems and methods for modeling floods

A flood modeling system defines virtual cells of a geographic region. Some of the cells, referred to as “channel cells,” represent areas within a channel for a moving body of water, such as a stream or river. Other cells, referred to as “land cells,” represent areas external to the channels within the geographic region. The flow of water through the geographic region is modeled as a virtual flow of water through the channel cells and the land cells. The virtual flow of water through the channel cells is modeled via a channel flow algorithm, and the virtual flow of water through the land cells is modeled via a land flow algorithm. For each time step, the system calculates the amount of water that virtually flows out of one cell into adjacent cells. Thus, for any given time step, each cell has an estimated amount of water virtually contained within the cell. The water estimated to virtually flow above ground represents flood water and can be quantified for each cell. Thus, data indicative of the amount of water estimated to be above ground for the land cells can be used to generate an inundation map or for other purposes, such as initiating flood warnings for areas that are modeled to experience a significant amount of flooding.
