Description

  In the present invention, when a fire occurs in a dust container of a garbage truck, it is detected at an early stage and this is notified to the driver's seat, and a change in temperature due to a fire in the dust container is detected. The present invention relates to a device that informs a driver's seat of judgment information such as fire spread and fire extinguishing, and a device that suppresses the spread of a fire in a dust storage box automatically or manually.

  A conventional device for detecting a fire in a dust storage box of a garbage collection vehicle is disclosed in Patent Document 1 in a gap in a portion where a dust storage box communicates with a dust input box pivotally supported on the upper rear side of the dust storage box. There is a detector with a smoke detector on top.

  Further, in Patent Document 2, smoke is placed on the upper part of the shielding plate extending over the entire width direction of the dust container so as to separate the dust chamber of the dust container and the loading device of the dust container. There is a smoke storage unit having a smoke inflow hole through which a smoke can flow and a smoke detection device for detecting smoke in the smoke storage unit.

  In addition, the utility model document 3 has a sensor for detecting the occurrence of a fire inside the garbage storage box.

  Next, regarding a fire suppression device in a dust container of a garbage truck, nitrogen gas, water, exhaust gas, inert gas, carbon dioxide, water vapor, and fire extinguishing liquid are discharged into the dust container as described in Patent Document 4, etc. Each discharge device has been proposed.

  However, in the case of Patent Document 1, the detection device may generate a fire if the fire spreads in the dust storage box and the dust storage box is filled with smoke and waits for smoke to blow out to the outside. Missed detection and missed initial fire fighting opportunity.

  In the case of Patent Document 2, there is a gap in the portion where the dust container and the dust box are connected near the upper part of the smoke inflow hole, and after the dust container is filled with smoke, The inflow of smoke through the smoke inflow holes formed by a large number of apertures into the sealed smoke containing portion is small, detection is delayed, and the opportunity for initial fire extinguishing is missed.

  In the case of Utility Model Document 3, the throwing-in dust is pushed into the dust storage box at a high pressure by the loading device, and a large pressure is applied to the inside. Since it is a discharge, the installation of the internal protrusion by attaching the sensor to the dust storage box is not suitable for the installation of the sensor inside the dust storage box because there is an obstacle to the discharge.

  Based on the above, the present invention is a dust collection system that detects fires in the garbage storage box of a garbage collection vehicle at an early stage and does not miss the opportunity of initial fire extinguishing, and informs the driver's seat of judgment information such as the spread of fire and extinguishing An object of the present invention is to provide a fire detection device in a garbage storage box of a car.

  Moreover, about the fire suppression apparatus in the refuse storage box of a garbage collection vehicle, each patent document 4 etc. discharges nitrogen gas, water, exhaust gas, an inert gas, a carbon dioxide, water vapor | steam, and digestive liquid in a dust storage box. Discharge devices have been proposed, but each has a large facility, is expensive, and has not yet become widespread. Further, many of the conventional devices have insufficient measures for cases where there is no person in the driver's seat at the time of a fire or when the device cannot be operated due to a failure in the electrical system. The present invention is inexpensive, easy to spread, and can suppress fire in the garbage collection box of a garbage collection vehicle that can respond to fire even when there is no person in the driver's seat at the time of a fire or when the device can not operate due to failure of the electrical system An object is to provide an apparatus.

  In order to solve the above-mentioned problems, a device of claim 1 is provided on a loading platform behind a driver's seat of a garbage collection vehicle, is tilted by a storage box drive device, and has an opening at the rear, A dust input box that communicates with the storage box, is pivotally supported on the rear upper end side of the dust storage box, and is rotationally driven by the input box driving device, and the dust that has been input into the dust input box is stored in the dust storage box. In a refuse collection vehicle including a loading device, a smoke sensor and / or a temperature sensor is attached to the outside of the ceiling of the refuse storage box of the dust collection vehicle, and the detection information of the sensor is received at the driver's seat of the dust collection vehicle A device for suppressing fire detection in a dust container of a garbage truck characterized by being equipped with a receiving device.

  The invention of claim 2 further includes a shielding plate extending over the entire width direction of the dust container so as to separate the dust chamber of the dust container and the loading device of the dust container. In the garbage collection vehicle, a foam fire extinguishing device that blocks inflow and outflow of air around the shielding plate is attached to the shielding plate.

  In the invention of claim 3, when a fire occurs in the refuse storage box and the temperature exceeds a preset temperature, an automatic operation device for operating an electric valve of the foam extinguishing device and a manual operation of the foam extinguishing device A manual operation device for operating the valve and an operation stop device for stopping the operation of the foam extinguishing device by pressing a stop button attached to the driver's seat are mounted.

    According to the first aspect of the present invention, when a fire occurs in the garbage storage box, the smoke gathers on the ceiling of the dust storage box, so that the smoke can be detected early and notified to the driver's seat. Is possible. In addition, the temperature sensor's detection information can be used to determine changes in the temperature inside the trash storage box, which can be useful in determining whether fire spreads or extinguishes.

  According to the invention of claim 2, if a foam fire extinguishing device is attached to the shielding plate, it can be provided at a lower cost than other large-scale equipment and is easy to spread.

  According to the third aspect of the present invention, it is possible to cope with a fire even when there is no person in the driver's seat at the time of a fire or when the device cannot be operated due to a failure of the electric system.

1 is a schematic side view of a garbage truck showing an embodiment of the present invention.

  An embodiment according to the present invention will be described below with reference to FIG.

  The smoke sensor 1 and / or the temperature sensor 2 are attached to the outside of the ceiling of the dust container 14 of the garbage collection vehicle 14, and the receiver 15 receives the detection information of the smoke sensor 1 and the temperature sensor 2 in the driver's seat 14 a of the dust collection vehicle 14. Attached. In this case, the transmission / reception is performed wirelessly, but it may be wired. Further, a foam extinguishing device 4 that blocks outflow and inflow of air around the shielding plate 12 was attached to the shielding plate 12 in the dust box 11. Furthermore, when a fire occurs in the dust container 10 and the temperature exceeds a preset temperature, an automatic operation device 7 for operating the electric valve 5 of the foam extinguishing device 4 and a manual valve 6 of the foam extinguishing device 4 are provided. The manual operation device 8 to be operated and the operation stop device 13 to stop the operation of the foam extinguishing device by pressing the stop button 16 attached to the driver's seat 14a were mounted.
