Description

Technical Field

[0001] The present invention belongs to the field of fire-fighting intelligent vehicle-mounted platforms, and in particular relates to a fire-fighting and rescue intelligent vehicle platform. Background Art

[0002] At present, most firefighting robots lack high-temperature protection functions, so they mainly perform remote firefighting outside the fire scene and cannot go deep into the fire scene. The traditional thermal protection method is to use a high-temperature resistant protective shell, set a cooling system inside the vehicle body, or set a spraying device on the top of the vehicle body. For the last method, since only a spraying device is set on the top of the vehicle body, it is difficult to effectively cool the vehicle body, especially the bottom of the vehicle body; in addition, the existing spraying device cannot adaptively adjust the spraying method according to the different working environment temperatures, resulting in waste of water resources or failure to quickly extinguish the fire. For example, if the working environment temperature is not very high, if the whole process uses the method of spraying water columns for cooling, it will obviously consume more water resources; if the robot encounters a fire on the road, it is difficult to quickly extinguish it only by spraying water mist. Therefore, it is necessary to improve the existing robot (or vehicle-mounted) platform to solve the above problems. Summary of the invention

[0006] Furthermore, a mounting frame is installed at the rear of the heat dissipation shell, and a water inlet pipe and a water outlet pipe respectively connected to the two heat dissipation chambers are installed on the mounting frame.

[0007] Further, the lifting water inlet assembly includes a connecting pipe, a lifting seat, a spring and a heat insulation plate, the lifting seat is a shell structure with a hollow interior and its upper end is connected to the connecting pipe, the upper end of the connecting pipe extends to the internal cavity of the heat dissipation shell and is slidably connected to the heat dissipation shell, the circumferential side wall of the lifting seat is provided with a plurality of drainage holes connected to the drainage area, and the side wall of the mounting hole is provided with a drainage channel connected to the upper drainage area and the lower drainage area;

[0012] Furthermore, the end cover is detachably connected to the lower end of the mounting hole.

[0013] The advantages of the present invention are:

[0014] 1. The present invention can achieve water cooling of the main part of the vehicle body with the help of the heat dissipation shell, and because a spray component is also arranged at the lower end of the heat dissipation shell, the cooling effect can be further improved and the consumption of water resources can be reduced; and when the smart car encounters a fire on the road, especially when the fire occurs under the vehicle body, the inert gas can quickly sense the change of the temperature under the vehicle and switch to the spray nozzle in time to complete the rapid disposal of the fire.

A heat dissipation shell 1 is installed on the periphery of the vehicle body 200 and can cool the vehicle body 200 by water. The vehicle body 200 can adopt a remotely controllable vehicle body structure of an existing technical platform to facilitate remote control of fire extinguishing. A spray assembly 5 is installed at the lower end of the heat dissipation shell 1. A partition 40 is provided in the internal cavity of the heat dissipation shell 1 to divide the internal cavity of the heat dissipation shell 1 into two heat dissipation chambers 4. A connecting hole for connecting the two heat dissipation chambers 4 is provided on the partition 40 at the front end. A mounting frame 6 is installed at the rear of the heat dissipation shell 1. A water inlet pipe 2 and a water outlet pipe 3 respectively connected to the two heat dissipation chambers 4 are installed on the mounting frame 6.

[0027] The spray assembly 5 includes a liquid discharge housing 50, an atomizing nozzle 51, a spray nozzle 52 and a lifting water inlet assembly 53. The liquid discharge housing 50, which is hollow inside and cylindrical in shape, is installed at the lower end of the heat dissipation housing 1. The liquid discharge housing 50 is provided with a plurality of vertical and circumferentially arranged partitions 500 to further divide the internal cavity of the liquid discharge housing 50 into a plurality of fan-shaped drainage areas 502. The liquid discharge housing 50 is also provided with a horizontal partition 3 501 to further divide the drainage area 502 into an upper drainage area and a lower drainage area. The lower end of the liquid discharge housing 50 is provided with a plurality of partitions 501 arranged in a horizontal direction to further divide the drainage area 502 into an upper drainage area and a lower drainage area. A spray nozzle 52 connected to the upper and lower drainage areas and an atomizing nozzle 51 connected to the lower drainage area, and a spray nozzle 52 is arranged between two adjacent atomizing nozzles 51, the atomizing nozzle 51 and the spray nozzle 52 are arranged circumferentially along the axis of the cylindrical drainage shell 50, and the axis of the drainage shell 50 is also provided with a mounting hole 504, and the mounting hole 504 is installed with the lifting water inlet component 53, the lifting water inlet component 53 can move up and down and switch positions according to the change of temperature to realize the cooling water discharged from the atomizing nozzle 51 or the spray nozzle 52 through the heat dissipation shell 1.

[0028] The lifting water inlet assembly 53 includes a connecting pipe 530, a lifting seat 531, a spring 535 and a heat insulation plate 533. The lifting seat 531 is a shell structure with a hollow interior and its upper end is connected to the connecting pipe 530. The upper end of the connecting pipe 530 extends to the inner cavity of the heat dissipation shell 1 and is slidably connected to the heat dissipation shell 1. The circumferential side wall of the lifting seat 531 is provided with a plurality of drainage holes 532 connected to the drainage area 502. The side wall of the mounting hole 504 is provided with drainage channels 503505 connected to the upper drainage area and the lower drainage area.

[0029] The spring 535 is sleeved on the connecting pipe 530 and is located between the lifting seat 531 and the heat dissipation housing 1. The lower end of the lifting seat 531 is fixed with a heat insulation plate 533. The lower end of the mounting hole 504 is sealed by an end cover 534 (a detachable connection method such as screw connection can be adopted). The expansion chamber 536 formed by the heat insulation plate 533, the end cover 534 and the mounting hole 504 is filled with an inert gas. The reason for using the inert gas is that the chemical properties of the inert gas are inactive and it is difficult to react chemically with other substances. Therefore, it is suitable for fire fighting and disaster relief. The filling amount of the inert gas can be determined according to the test to ensure that the air pressure in the expansion chamber 536 can be It can reach the expected value under different temperature conditions, and thus smoothly complete the switching between water mist and water column; and the end cover 534 is made of heat-conducting material, which can quickly conduct the heat of the surrounding environment below the vehicle body 2 to the expansion chamber 117; the heat insulation plate 533 is made of heat-insulating material, and the inner wall of the mounting hole 504 is provided with a heat-insulating coating, which can reduce the influence of the cooling water in the lifting seat 531 and the drainage shell 50 on the inert gas, and work together with the end cover 534 to make the temperature in the expansion chamber 536 tend to be consistent with the external environment temperature at the lower end of the vehicle body 200, so as to better reflect the actual situation and make accurate execution actions.

[0030] In this embodiment, in order to ensure that the lifting seat 531 does not rotate in the horizontal direction, a vertical slider 537 is provided on the outer side of the lifting seat 531 , and a guide groove 538 matching with the slider 537 is provided in the mounting hole 504 .

[0031] In this embodiment, in order to ensure the sealing between the connecting pipe 530 and the heat dissipation housing 1, a sliding hole matching with the connecting pipe 530 is provided on the heat dissipation housing 1, and a sealing member slidably connected with the connecting pipe 530 is installed at the lower end of the sliding hole.

[0032] The working process and principle of the present invention are as follows:

[0033] First, the water inlet pipe 2 and the drain pipe are connected to the corresponding water pipes, and cooling water is introduced into the water inlet pipe 2. After the vehicle body 200 moves to the fire scene via the crawler-type walking mechanism 100, the main part of the vehicle body 200 has the heat dissipation shell 1 and the cooling water inside it for cooling;

[0034] If the ambient temperature is at a low level, the inert gas pressure in the expansion chamber 536 is small, and the lifting seat 531 is at the lowest point under the action of the spring 535. The drainage hole 532 arranged on the side wall of the lifting seat 531 is connected to the lower drainage area connected to the atomizing nozzle 51. At this time, the cooling water in the internal cavity of the heat dissipation housing 1 is finally sprayed out by the atomizing nozzle 51, and the vehicle body 200 and the crawler walking mechanism 100 are cooled by the water mist.

[0035] If the ambient temperature is at a relatively high level, the inert gas pressure in the expansion chamber 536 increases and pushes the lifting seat 531 to rise, so that the drainage hole 532 arranged on the side wall of the lifting seat 531 is connected to the upper drainage area connected to the spray nozzle 52. At this time, the cooling water in the internal cavity of the heat dissipation shell 1 is finally sprayed out by the spray nozzle 52, and the vehicle body 200 and the crawler walking mechanism 100 are quickly cooled down by the water column; and in the event of a fire under the vehicle body 200, the inert gas expands rapidly after being heated, and the gas pressure increases, and the cooling water sprayed from the spray nozzle 52 can quickly extinguish the fire.

[0036] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
