Definitions

  • This invention relates generally to fluid jet systems.
  • Fluid jet systems have many applications, such as firefighting, military/law
  • Typical fluid jet systems provide a cutting or abrading function by projecting a jet of fluid at high velocity and pressure at a structure or surface.
  • the specific fluid employed depends on the application. For example, for firefighting applications, a combination of water and an abrasive material may be employed to penetrate a wall or ceiling of a structure having a fire within. Upon creating a hole in the wall or ceiling, the abrasive material flow may be terminated while continuing the water flow through the hole to knock down the fire within the structure.
  • a fluid jet lance can include a camera mount configured to selectively position a thermal imaging camera in a line of sight of a user.
  • the thermal imaging lance can be utilized by orienting a thermal imaging camera attached to the fluid jet lance in an operator's line of sight with a solid surface. The lance may then be aimed at a target behind the solid surface. The solid surface may be penetrated by using a jet of fluid emitted from the lance. And, a jet of fluid may be dispensed at the target.
  • an apparatus can include a fluid jet lance as well as a source of abrasive material coupled with the fluid jet lance.
  • a source of a chemical agent may also be coupled with the fluid jet lance.

  • Fluid jet systems are extremely useful. Nevertheless, it can be difficult to know the environmental conditions (e.g., temperatures) within the structure prior to and after making penetration using the projected jet of fluid. Knowing the environmental conditions and effectively communicating those conditions to an operator of the fluid jet system could resolve certain safety and maintenance concerns and improve performance of the fluid jet system.
  • environmental conditions e.g., temperatures
  • FIG. 1 illustrates an example fluid jet system 100 with an integrated thermal imaging camera 101 used in a firefighting application, the example fluid jet system 100 including a fluid jet base station 102 and a fluid jet assembly 104 (also referred to as a lance 104).
  • the camera can include both a sensor to gather image data as well as a display screen to display the image data.
  • Example fluids used in the fluid jet system 100 include a fluid (e.g., water), combinations of the fluid and an abrasive material, and combinations of the fluid and foam.
  • the specific fluid employed depends on the particular application for the fluid jet system 100. For example, a flow of fire retardant foam may be combined with the water flow to enhance the suppression of a fire 112 (e.g., by coating the fire's fuel to reduce its contact with oxygen).
  • an operator 106 e.g., a firefighter
  • the lance 104 includes the integrated thermal imaging
  • the operator 106 allows the operator 106 to view thermal conditions within the enclosure 110 in order to decide how best to use the lance 104. For example, if the peak temperature within the enclosure 110 exceeds a threshold, the operator 106 may become aware of the fire 112 within the enclosure 110 and use the fluid jet system 100 to control and/or extinguish the fire 112. Further, if the peak temperature within the enclosure 110 drops below a threshold while the operator 106 is using the fluid jet system 100, the operator 106 may observe that the fire 112 has been extinguished and/or is under sufficient control to permit entry into the enclosure 110 to firefighters to continue fighting the fire 112 or survey damage caused by the fire.
  • the thermal imaging camera 101 (or thermographic camera) can render infrared radiation as visible light in real-time (with perhaps some delay). As a result, the operator 106 may use the thermal imaging camera 101 to see heat through smoke, darkness, the wall 108, or other heat-permeable barriers.
  • the thermal imaging camera 101 includes a heat and/or water resistant housing to prevent damage to the thermal imaging camera 101 in the field.
  • the lance 104 further includes a rigid lance barrel through which high-pressure fluid flows during operation.
  • the rigid lance barrel allows the operator 106 to accurately direct the fluid flow and to steady the lance 104 against the wall 108.
  • the operator 106 initially cuts through the wall 108 using a combined flow of high-pressure water and abrasive material. When the wall 108 is penetrated, the operator 106 ceases the flow of abrasive material while continuing the flow of water, which streams into the enclosure 110 through the newly cut hole 114 in the wall 108 in a high-pressure jet 116 having a small water droplet size (e.g., approximately 0.0059 inches or 150 microns in diameter) and a high velocity (e.g., approximately 400-450 mile per hour or 200 meters per second).
  • a small water droplet size e.g., approximately 0.0059 inches or 150 microns in diameter
  • a high velocity e.g., approximately 400-450 mile per hour or 200 meters per second.
  • high-pressure jet 116 may extend a considerable distance (e.g., over 40 feet) into the enclosure 110, despite convection currents caused by the fire 112, and knocks down the fire 112.
  • Much of the water in the high-pressure jet 116 is vaporized (as shown by steam 118), reducing the intensity of the fire 112 and the temperature within the enclosure 110.
  • the fluid jet system 100 knocks down the fire 112 and makes it safer for firefighters to enter the enclosure 110 to progress their firefighting activities.
  • the operator 106 may use information from the thermal imaging camera 101 to fine tune the velocity (direction and/or speed) of the high pressure jet 116 so that it is most effectively directed to knock down the fire 112.
  • the operator 106 takes a steady stance, holds the lance 104 against his shoulder and with both hands (e.g., one hand in the trigger guard of the lance 104 and the other on a barrel handle 103 located forward of the trigger guard on the lance barrel), and places a placement structure 105 at the distal end of the lance 104 against the wall 108.
  • the lance 104 may be configured for right-handed, left-handed, or ambidextrous use. More specifically, the thermal imaging camera 101 may be selectively placed on the left side or right side of the lance 104 depending on the operator's placement of his/her head relative to the lance. Further, the thermal imaging camera 101 may be selectively placed in the middle of the lance 104 for storage and/or transport of the lance 104. This position may serve to reduce the overall size of the lance 104 and/or protect the thermal imaging camera 101 during storage and/or transport of the lance 104. The thermal imaging camera 101 may also be angle, distance, and/or height adjustable to be most
  • the barrel handle 103 may actually include two handles or the barrel handle 103 is moveable to suit both left-handed and right-handed operators.
  • the placement structure 105 of the lance includes a 3 -pronged offset fixture with a splash plate to protect the operator 106 from spray-back of fluid and debris during the cutting operation.
  • Other placement structures may be employed to steady or aim the fluid jet 116 at a target region of the structure 110.
  • cutting performance of the fluid jet 116 is improved if the placement structure allows the operator 106 to "wiggle" the fluid jet 116 about the target region. In this manner, the hole 114 that is cut in the structure 110 by the fluid jet 116 develops as larger diameter than the fluid jet 116 itself, thereby allowing fluid and debris to evacuate during the cutting operation.
  • the lance 104 includes two triggers: (1) a trigger to control the flow of water from the fluid jet base station 102 through the lance 104; and (2) a trigger to control the flow of abrasive material from an abrasives holding tank in the fluid jet base station 102 through the lance 104.
