DETAILED DESCRIPTION

[0068] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in conjunction with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0069] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , now a multifunctional video inspection device provided by the present application will be described. The multifunctional video inspection device comprises a vehicle body 1, further comprises a liquefied gas tank 2, a first driving assembly, a camera assembly 4, a second driving assembly, a connecting pipe 6, a spray head 7, a third driving assembly and a first valve 9.

[0070] The liquefied gas tank 2 is rotatably connected with the vehicle body 1 around a vertical axis and is used for storing liquid carbon dioxide.

[0071] The first driving assembly is arranged on the vehicle body 1 and is used for driving the liquefied gas tank 2 to rotate.

[0072] The camera assembly 4 is rotatably connected with the liquefied gas tank 2 around a first horizontal axis.

[0073] The second driving assembly is arranged on the liquefied gas tank 2 and is used for driving the camera assembly 4 to rotate.

[0074] One end of the connecting pipe 6 is fixedly connected with the liquefied gas tank 2 and is in communication with the liquefied gas tank 2.

[0075] The spray head 7 is rotationally connected with the connecting pipe 6 around the second horizontal axis, the spray head 7 is connected with the other end of the connecting pipe 6 by means of the hose 71 and is in communication.

[0076] The third driving assembly is arranged on the connecting pipe 6 and is used for driving the spray head 7 to rotate.

[0077] The first valve 9 is arranged on the connecting pipe 6.

[0078] During the movement of the vehicle body 1, the first driving assembly drives the liquefied gas tank 2 to rotate, so that the camera assembly 4 can patrol around the vehicle body 1, meanwhile, the second driving assembly drives the camera assembly 4 to rotate, so that the height of the patrol of the camera assembly 4 can be adjusted, so that the machine room can be patrolled in all directions.

[0079] When the fire is found, the first driving assembly drives the liquefied gas tank 2 to rotate, so that the spray head 7 is directed to the side of the vehicle body 1 corresponding to the fire, the third driving assembly drives the spray head 7 to rotate, so that the height of the spray head 7 spraying the liquid carbon dioxide is adjusted, so that the spray head 7 is aimed at the ignition point. Then when the first valve 9 is opened, the liquid carbon dioxide in the liquefied gas tank 2 is sprayed out along the connecting pipe 6, the hose 71 and the spray head 7, so that the fire extinguishing by the liquid carbon dioxide is realized.

[0080] Compared with the prior art, the multifunctional video inspection device provided by the application can patrol around the vehicle body 1 by driving the liquefied gas tank 2 to rotate by the first driving assembly and driving the camera assembly 4 to rotate by the second driving assembly during the movement of the vehicle body 1 along the preset path, when the fire occurs, the spray head 7 can be aimed at the ignition point by driving the liquefied gas tank 2 to rotate by the first driving assembly and driving the spray head 7 to rotate by the third driving assembly, the liquid carbon dioxide in the liquefied gas tank 2 can be sprayed to the ignition point by opening the first valve 9, so that the fire extinguishing effect is achieved, and the problem that the existing video inspection device cannot extinguish the fire when the fire is found because the existing video inspection device does not have the fire extinguishing function is avoided.

[0081] The heat absorption during the gasification of the liquid carbon dioxide after covering the ignition point can realize the fire extinguishing.

[0082] In the embodiment, the camera assembly 4 can use a binocular camera, the hose 71 can use a metal hose 71, and the first valve 9 can use an electromagnetic valve.

[0083] Further, the spray head 7 and the camera assembly 4 can be arranged on the same side of the vehicle body 1 and the first horizontal axis and the second horizontal axis are parallel, so that when the camera assembly 4 discovers a fire, the spray head 7 can be driven to rotate to aim at the fire point for fire extinguishing, and the camera assembly 4 can be used to observe the fire extinguishing situation.

[0084] In some embodiments, the liquefied gas tank 2 can have a structure as shown in Figure 5 and Figure 7 . Referring to Figure 5 and Figure 7 , the liquefied gas tank 2 comprises a tank body 21, a blocking cover 22 and a first sealing gasket 23.

[0085] The tank body 21 is a hollow cylindrical structure with an axis vertically arranged, and the top end of the tank body 21 is an open end. The inner wall of the top end of the tank body 21 has a limiting portion 211 protruding inward.

[0086] The blocking cover 22 is slidably arranged in the tank body 21, and the blocking cover 22 and the tank body 21 form a containing cavity 24 for containing liquid carbon dioxide. The blocking cover 22 supports the camera assembly 4 and the first driving assembly.

[0087] The first sealing gasket 23 is located in the containing cavity 24 and fixedly attached to the blocking cover 22. The first sealing gasket 23 is circumferentially attached to the inner wall of the tank body 21.

[0088] One end of the connecting pipe 6 is fixedly arranged on the tank body 21 and connected to the bottom of the containing cavity 24.

[0089] When the containing cavity 24 is filled with liquid carbon dioxide, the blocking cover 22 abuts against the limiting portion 211. When the liquid carbon dioxide in the containing cavity 24 is sprayed out of the spray head 7 for fire extinguishing, the pressure in the containing cavity 24 decreases. At this time, the blocking cover 22 can slide downward under the action of its own gravity and the gravity of the camera assembly 4 and the first driving assembly, so as to reduce the volume of the containing cavity 24 and keep a certain pressure in the containing cavity 24, so that as much liquid carbon dioxide as possible in the containing cavity 24 can be sprayed out of the spray head 7.

[0090] The first sealing gasket 23 can ensure the sealing between the tank body 21 and the blocking cover 22.

[0091] In some embodiments, referring to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6The connecting pipe 6 is located at the side of the tank body 21 and has a first vertical section 61 arranged vertically, the spray head 7 is connected with the top end of the first vertical section 61 by a hose 71 and communicates with the first vertical section 61, and the multifunctional video inspection device further comprises a first support 10, a second fixed pipe 110, a blocking shaft 120, a second sealing gasket 130, a push plate 140, a sliding shaft 150 and a compression spring 151.

[0092] The first support 10 has a vertical column 101 arranged vertically and fixed to the blocking cover 22, and a first fixed pipe 102 arranged horizontally and having one end fixed to the vertical column 101, the other end of the first fixed pipe 102 facing the first vertical section 61, the camera assembly 4 is rotationally connected with the first support 10 about a first horizontal axis, and the second drive assembly is arranged on the first support 10.

[0093] The second fixed pipe 110 is coaxially arranged with the first fixed pipe 102, one end of the second fixed pipe 110 is fixedly connected with and communicates with the first vertical section 61, and the other end of the second fixed pipe 110 faces the first fixed pipe 102 and has a gap with the first fixed pipe 102.

[0094] The blocking shaft 120 has two ends slidingly penetrating into the first fixed pipe 102 and the second fixed pipe 110, respectively, and the side wall of the blocking shaft 120 has an outwardly protruding connecting portion 1201 located between the second fixed pipe 110 and the first fixed pipe 102.

[0095] The second sealing gasket 130 is located in the second fixed pipe 110 and is fixedly attached to the blocking shaft 120, and the second sealing gasket 130 is circumferentially attached to the inner wall of the second fixed pipe 110.

[0096] The push plate 140 is perpendicular to the second fixed pipe 110 and is fixedly sleeved on the second fixed pipe 110.

[0097] The sliding shaft 150 is parallel to the blocking shaft 120 and slidingly penetrates through the push plate 140, the sliding shaft 150 is fixedly connected with the connecting portion 1201, and the side wall of the sliding shaft 150 has an outwardly protruding abutting portion 1501 located on the side of the push plate 140 away from the abutting portion 1501.

[0098] The compression spring 151 is sleeved on the sliding shaft 150 and has two ends abutting with the push plate 140 and the abutting portion 1501, respectively.

[0099] The first valve 9 is arranged in the first vertical section 61 and located above the communication position between the first vertical section 61 and the second fixed pipe 110.

[0100] The pressure in the first vertical section 61 is equal to the pressure in the containing cavity 24, and the pressure in the first vertical section 61 is transmitted to the blocking shaft 120 through the second fixed tube 110, so that the blocking shaft 120 is kept in the state of penetrating into the first fixed tube 102 by overcoming the elastic force of the compression spring 151. When the liquid carbon dioxide sprayed by the spray head 7 can quickly extinguish the fire, that is, a certain amount of liquid carbon dioxide remains in the containing cavity 24, the first valve 9 can be closed at this time, and the blocking shaft 120 will slide a distance in the direction of the first vertical section 61 under the elastic force of the compression spring 151, but the blocking shaft 120 still remains in the first fixed tube 102, thereby limiting the downward sliding of the blocking cover 22, so that the camera assembly 4 still maintains the initial height, and thus the multifunctional video inspection device can continue to perform inspection. When a large amount of liquid carbon dioxide is sprayed by the spray head 7 and still cannot extinguish the fire, so that the pressure in the containing cavity 24 is less than a predetermined value, the blocking shaft 120 completely exits the first fixed tube 102 under the elastic force of the compression spring 151, and the blocking cover 22 slides downward, so that the liquid carbon dioxide in the containing cavity 24 can be sprayed out of the spray head 7 as much as possible.

[0101] The second sealing gasket 130 can ensure the sealing between the blocking shaft 120 and the second fixed tube 110.

[0102] Further, the second sealing gasket 130 can be limited in the first vertical section 61 by the push plate 140, so as to prevent the second sealing gasket 130 from penetrating into the first vertical section 61.

[0103] In some embodiments, referring to Figure 1 、 Figure 5 、 Figure 7 and Figure 8 , the multifunctional video inspection device further comprises a filter tank 160, a filter screen 170, an air inlet pipe 180, an air outlet pipe 190, and an air extractor 200.

[0104] The filter tank 160 is located at the side of the tank body 21 and fixedly connected with the tank body 21, and the filter tank 160 is provided with a filter cavity 1601.

[0105] The filter screen 170 is located in the filter cavity 1601 and fixedly connected with the filter tank 160, and the filter screen 170 divides the filter cavity 1601 into an air outlet part 16011 and an air inlet part 16012 located at one side of the air outlet part 16011.

[0106] The air inlet pipe 180 is connected with the filter tank 160 and communicates with the air inlet part 16012.

[0107] The air outlet pipe 190 is connected with the filter tank 160 and communicates with the air outlet part 16011.

[0108] The air inlet of the air extractor 200 is connected with and communicates with the air outlet pipe 190.

[0109] When the air extractor 200 works, the air in the machine room enters the air inlet part 16012 through the air inlet pipe 180, is filtered by the filter screen 170, enters the air outlet pipe 190, and is then extracted by the air extractor 200 along the air outlet pipe 190. In this way, the impurities in the air can be filtered while the inspection is performed.

[0110] In some embodiments, referring to Figure 1 , Figure 5 , Figure 6 and Figure 7 , the air inlet part 16012 is located at one side of the air outlet part 16011 in the horizontal direction, the air outlet pipe 190 has a second vertical section 1901 which is vertically arranged and has a closed bottom end, the air inlet pipe 180 is a straight pipe which is vertically arranged and has a closed bottom end, the side wall of the second vertical section 1901 is provided with a plurality of air outlet holes 19011 which are located in the air outlet part 16011, the air inlet pipe 180 is provided with a plurality of air inlet holes 1801 which are located in the air inlet part 16012, the filter tank 160 is further provided with a spraying cavity 1602 which is located below the filter cavity 1601 and has a bottom part for storing water, the filter tank 160 has a partition plate 1603 for separating the filter tank 160 into the filter cavity 1601 and the spraying cavity 1602, the second vertical section 1901 and the air inlet pipe 180 both slide through the top wall of the filter cavity 1601 and the partition plate 1603, and the multifunctional video inspection device further comprises a spraying head 210, a spraying pipe 220, a filter valve 230 and a water pump 240.

[0111] The spraying head 210 is located above the liquid level in the spraying cavity 1602 and can spray downward.

[0112] One end of the spraying pipe 220 is fixedly connected with the bottom wall of the filter tank 160 and communicates with the bottom part in the spraying cavity 1602, the middle part penetrates through the side wall of the filter tank 160 and is fixedly connected with the filter tank 160, and the other end is located in the spraying cavity 1602 and is connected with the spraying head 210.

[0113] The filter valve 230 is arranged on the spraying pipe 220.

[0114] The water pump 240 is arranged on the spraying pipe 220.

[0115] When the liquid carbon dioxide sprayed by the spray head 7 cannot extinguish the fire, the fire point will produce smoke and the temperature in the machine room will rise. At this time, the air inlet pipe 180 and the second vertical section 1901 are both slid downward until all the air inlet holes 1801 and the air outlet holes 19011 are located between the spray head 210 in the spray chamber 1602 and the liquid surface. The water pump 240 extracts the water at the bottom of the spray chamber 1602 and sprays it through the spray head 210. When the air extractor 200 is working, the smoke enters the spray chamber 1602 along the air inlet pipe 180. After being sprayed by the liquid sprayed by the spray head 210, the particles in the smoke will fall into the liquid at the bottom of the spray chamber 1602. The gas purified by spraying is extracted by the air extractor 200. In this way, the particles in the smoke can be prevented from threatening the subsequent fire extinguishing personnel, and since the temperature of the gas after being sprayed will be lowered, the temperature in the machine room can be lowered.

[0116] When the liquid flows through the spray pipe 220, the filter valve 230 can filter impurities in the liquid.

[0117] The air inlet pipe 180 communicates with the air inlet part 16012 or the spray chamber 1602 through the air inlet hole 1801, and the second vertical section 1901 communicates with the air outlet part 16011 or the spray chamber 1602 through the air outlet hole 19011.

[0128] The second valve 340 is arranged on the communication tube 330.

[0129] When the fixed plate 103 is attached to the upper end surface of the protection tube 320, the second valve 340 is opened, so that the gas extracted by the air extractor 200 can enter the first vertical section 61 through the communication tube 330 vertically, thereby being sprayed from the spray head 7. Since the temperature of the gas extracted by the air extractor 200 is low, the temperature near the ignition point can be reduced, thereby preventing the fire from expanding to a certain extent.

[0130] In the embodiment, the second valve 340 is an electromagnetic valve.

[0131] In some embodiments, referring to Figure 1 and Figure 2 A multifunctional video inspection device further comprises a second support 260, a first connecting shaft 270 and a ring sleeve 280.
