[0002] The construction machinery cab assembly is an important part of the construction machinery vehicle. It integrates all the main components and functions of the cab to provide a safe and comfortable working environment for the driver. The construction machinery cab assembly also integrates an alarm function to ensure that the construction machinery can promptly alarm and alert the staff in the event of a malfunction or danger. The alarm system of the construction machinery cab assembly is mostly an alarm light installed on the top of the outside, which plays an alarm role through the flashing of the alarm light and the sound.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] like Figures 1 to 11 As shown, an engineering machinery cab assembly with automatic accident alarm described in an embodiment of the present invention comprises a cab body 1, both sides of the cab body 1 are rotatably connected with side doors 2, glass windows 3 are installed on the side doors 2, and warning lights 4 and lighting lights 5 are installed on the top of the cab body 1; both sides of the cab body 1 are provided with cooling mechanisms 10, the cooling mechanism 10 comprises a water tank 11 fixedly installed on one side of the cab body 1, a water storage box 12 is fixedly installed on one side of the side door 2, and a water storage box 12 is fixedly installed inside A pump, a water pump is fixedly installed with a water suction pipe 13 at one end, and the end of the water suction pipe 13 away from the water pump is connected to the water tank 11. A plurality of water flow holes are opened at the bottom of the water storage box 12, and a storage frame 14 connected to the inside is fixedly installed on the top of the water storage box 12. A shell 15 is fixedly installed on the top of the cab body 1, and a solar panel 16 is installed in the shell 15. A guide groove is opened on the top of the shell 15, and a guide pipe 17 connected to the guide groove is fixedly installed on one side of the shell 15, and the guide pipe 17 is connected to the storage frame 14. The extension component 80 includes an extension frame 81 that is connected and slidable with the inside of the water storage box 12 through a spring, and a plurality of water flow holes are opened at the bottom of the extension frame 81, and a plurality of positioning holes 82 are opened at the top of the extension frame 81. A positioning rod 83 is slidably inserted at the top of the water storage box 12.

[0025] Specifically, a plurality of extension tubes 18 connected to the inside are fixedly installed on one side of the water storage box 12, and an atomizing nozzle 19 in the cab body 1 is fixedly installed on one end of the extension tube 18 away from the water storage box 12. A filtering mechanism 30 for separating impurities is arranged in the storage frame 14, and the filtering mechanism 30 includes a filter screen 31 fixedly installed in the storage frame 14 and in an inclined shape, and a rotating plate 32 is rotatably connected in the storage frame 14 through a torsion spring, and an arc-shaped scraper 33 is slidably connected at the bottom of the push plate 22 through a spring, and a recovery mechanism 40 for recycling the water flowing out of the water storage box 12 is arranged at the side door 2, and the recovery mechanism 40 includes a recovery box 41 fixedly installed at the side door 2, and the recovery box 41 is connected to the water tank 11 through a recovery tube 42, and two symmetrically arranged baffles 43 are fixedly installed on the top of the recovery box 41, and a slide plate 44 is slidably connected to the inside of the baffle 43, and a bolt 45 is threadedly connected to the inside of the baffle 43, and the baffle 43 and the slide plate 44 are both made of transparent materials.

[0026] During operation, the cab body 1 will be installed on the excavator and connected and adapted to various sensors on the excavator. Various sensors are installed on the excavator to monitor different parameters of the machine, such as engine temperature, hydraulic oil pressure, water temperature, fuel level, tire pressure, etc. At this time, the warning light 4 on the top of the cab body 1 is electrically connected to the sensors on the excavator. When the excavator fails or is in danger, these sensors will continuously send the detected data to the electronic control system or controller of the machine. At this time, the warning light 4 will flash and sound an alarm in time, thereby prompting the staff in the cab body 1 to stop working and carry out emergency repairs.

[0027] By starting the water pump in the water storage box 12, the water pump draws the water in the water tank 11 into the water storage box 12 through the pumping pipe 13, and then the water flows out through the water flow hole at the bottom of the water storage box 12, thereby forming a water curtain at the glass window 3 of the side door 2. At the same time, the extension frame 81 in the water storage box 12 can be adjusted by sliding, so that the extension frame 81 slides away from the water storage box 12, thereby extending the length of the water storage box 12, so that the water in the water storage box 12 flows into the extension frame 81 and then flows out through the water flow hole at the bottom, thereby adapting to glass windows 3 of different sizes, and also facilitating the operator in the cab body 1 to observe the rearview mirror through the glass. After the extension frame 81 is adjusted, the positioning rod 83 is inserted into the positioning hole 82, thereby realizing the function of quickly adjusting and fixing the extension frame 81. The design of the water curtain can effectively cool down the inside of the cab body 1. At the same time, the water curtain will not affect the driver's observation of the outside world through the glass window 3. The water curtain can also absorb dust while effectively reducing noise, preventing dust and impurities generated by engineering machinery when crushing stones from entering the cab body 1 through the gaps. Part of the water in the water storage box 12 will enter the atomizing nozzle 19 through the extension tube 18, and then spray into the cab body 1, and the atomized water will be used to humidify and cool the cab body 1. It should be noted that the side door 2 is opened by rotating in the direction of the water tank 11, so the water curtain, the water pumping pipe 13 and other components will not be affected when the side door 2 is opened.

[0028] The purpose of installing the storage frame 14 on the top of the water storage box 12 is to collect rain when it rains, thereby reducing the use of water in the water tank 11. Such a design can make full use of the water source in nature. At the same time, installing the filter 31 in the storage frame 14 can play a role in separating impurities, allowing water to flow into the water storage box 12 through the filter 31, while the impurities are blocked by the filter 31 and guided to the rotating plate 32 by the inclined filter 31. When it is necessary to clean the accumulated impurities, the electric push rod 21 is started, and the electric push rod 21 drives the scraper 33 to push the impurities remaining on the filter 31 to move to the rotating plate 32, and the arc-shaped scraper 33 is used to rotate and push the rotating plate 32 toward the direction of the water storage box 12. As the scraper 33 continues to move, the impurities are pushed out through the gap between the rotating plate 32 and the storage frame 14, achieving the function of cleaning the filter 31, so that it can work normally and efficiently, and after the scraper 33 no longer pushes against the rotating plate 32, the rotating plate 32 is reset under the action of the torsion spring.

[0029] The recovery box 41 is installed below the water storage box 12 to collect the water of the water curtain, and then guide the water back to the water tank 11 through the recovery pipe 42, so as to realize the reuse of water. The baffle 43 and the slide plate 44 are installed on the recovery box 41 to reduce the influence of natural wind on the water curtain, so that the water curtain falls into the recovery box 41 as much as possible. The slide plate 44 can slide to adjust the height as needed, and the slide plate 44 is fixed in the baffle plate 43 by bolts 45. The baffle plate 43 and the slide plate 44 made of transparent materials will not affect the driver's observation of the outside world.

[0030] By installing a solar panel 16 on the top of the cab body 1, the solar panel 16 absorbs the top sunlight and then converts it through a transformer to generate electricity for the water pump in the water storage box 12. At the same time, the installed solar panel 16 can also block the direct sunlight from the cab body 1. Since there is a certain gap between the solar panel 16 and the cab body 1, an overhead insulation layer is formed, and then the outdoor natural wind is used for heat dissipation to slow down the temperature rise inside the cab body 1. When it rains, rainwater will flow into the guide pipe 17 through the guide groove opened on the shell 15, and then enter the storage frame 14 through the guide pipe 17, thereby avoiding water turbulence and making effective and reasonable use of water resources.

[0031] An insect repellent mechanism 20 for repelling insects at the warning light 4 and the lighting light 5 is provided on the cab body 1. The insect repellent mechanism 20 includes an electric push rod 21 fixedly mounted on one side of the cab body 1, a push plate 22 fixedly mounted on the output end of the electric push rod 21, a support plate 23 fixedly mounted on the top of the cab body 1, a storage box 24 made of rubber material fixedly mounted on one side of the support plate 23, an insect repellent liquid pre-stored in the storage box 24, a liquid spraying pipe 25 installed on one side of the storage box 24, and a plurality of guide tubes 50 connected to the interior and in a "T" shape are fixedly mounted on the surface of the liquid spraying pipe 25.

[0032] Specifically, a support mechanism 60 for assisting the electric push rod 21 in moving is provided on one side of the cab body 1, and the support mechanism 60 includes a slide groove 61 opened on one side of the cab body 1, and a support block 62 is slidably connected inside the slide groove 61, and the end of the support block 62 away from the slide groove 61 is fixedly connected to the output end of the electric push rod 21, and a hollow elastic block 63 is fixedly installed inside the slide groove 61, and an air outlet pipe 64 connected to the elastic block 63 is fixedly installed on the top of the cab body 1, and the end of the air outlet pipe 64 away from the elastic block 63 is close to the lighting lamp 5.

[0033] During operation, the lighting lamp 5 on the top of the cab body 1 will be always on during nighttime operation, and the light in the outdoor environment will attract a large number of mosquitoes, which will gather at the lighting lamp 5 and affect the normal work of the driver. Therefore, a push plate 22 is installed on the electric push rod 21, so that the electric push rod 21 and the scraper 33 can continue to move toward the back plate 23 after cleaning the filter 31, and the storage box 24 on the back plate 23 is squeezed by the push plate 22, so that the insect repellent in the storage box 24 is squeezed into the spray pipe 25 and the guide pipe 50 and then sprayed toward the lighting lamp 5, so as to achieve the effect of repelling insects at the lighting lamp 5 and reduce the impact of mosquitoes on the driver.

[0034] At the same time, the output rod of the electric push rod 21 uses the support block 62 in the slide slot 61 to play the role of auxiliary support and sliding when moving. And the support block 62 will squeeze the elastic block 63 in the slide slot 61 when moving, so that the gas in the elastic block 63 can be blown to the lighting lamp 5 and the guide tube 50 through the air outlet pipe 64, so that the sprayed insect repellent can be blown to the far-end lighting lamp 5, avoiding the situation that the far-end lighting lamp 5 has an unsatisfactory insect repellent effect.

[0035] A cleaning mechanism 70 for cleaning the solar panel 16 is provided on the support block 62, and the cleaning mechanism 70 includes a connecting rod 71 fixedly mounted on the support block 62, a rectangular rod 72 is fixedly mounted on one side of the connecting rod 71, a cleaning cloth 73 in contact with the solar panel 16 is fixedly mounted on the surface of the rectangular rod 72, a plurality of guide columns 74 are rotatably connected to one side of the scraper 33, the cross-section of the rectangular rod 72 is rectangular, and the surface of the cleaning cloth 73 in contact with the solar panel 16 is a rectangular surface, and a protective cover 75 for storing the cleaning cloth 73 is fixedly mounted on the top of the shell 15, and a groove adapted to the rectangular rod 72 is provided on one side of the protective cover 75.

[0036] When working, the support block 62 will move with the connecting rod 71, the rectangular rod 72 and the cleaning cloth 73, and the rectangular surface of the rectangular rod 72 will be used to increase the contact area between the cleaning cloth 73 and the solar panel 16. The rectangular rod 72 cannot rotate, which improves the ability of the cleaning cloth 73 to wipe the surface of the solar panel 16, thereby reducing impurities remaining in the solar panel 16, causing the resistance of the solar panel internal cells to be uneven, so that the current in the area will decrease and the voltage will increase, resulting in excessive local temperature and forming a hot spot effect. When the electric push rod 21 resets with the support block 62, the support block 62 will also reset with the connecting rod 71, the rectangular rod 72 and the cleaning cloth 73. At this time, the rectangular rod 72 enters the groove of the shield 75, and the cleaning cloth 73 cooperates to enter the shield 75, thereby reducing the contamination of the cleaning cloth 73. It should be noted that when the support block 62 moves and resets with the connecting rod 71 and the push plate 22, the arc-shaped scraper 33 at the bottom of the push plate 22 will contact the storage frame 14 through the guide column 74, and then be lifted up to slide and shrink into the push plate 22, so that the scraper 33 no longer contacts the filter screen 31, so that it is above the storage frame 14. In this way, when the side door 2 is subsequently opened, since the scraper 33 is not in the storage frame 14, the side door 2 can be opened normally without being affected.

[0037] The interior of the cab body 1 is provided with an exhaust mechanism 90 for pre-cooling the interior, and the exhaust mechanism 90 includes a fixed cylinder 91 fixedly installed in the cab body 1, and the interior of the fixed cylinder 91 is sealed and slidably connected with a pull rod 92, one end of the pull rod 92 is fixedly connected to the support block 62, and an exhaust pipe 93 is fixedly installed on one side of the fixed cylinder 91, and a plurality of exhaust holes are opened on the surface of the exhaust pipe 93, and an exhaust pipe 94 outside the cab body 1 is fixedly installed on one end of the fixed cylinder 91, and both the exhaust pipe 93 and the exhaust pipe 94 are installed with a one-way valve, and bellows 95 are fixedly installed on both sides of the support block 62, and the end of the bellows 95 away from the support block 62 is fixedly connected to the cab body 1, and the top and bottom of the bellows 95 are in contact with the cab body 1.

[0038] When working, before starting to use the cab body 1, first start the electric push rod 21, so that it can pre-clean the filter 31 with the push plate 22 and the scraper 33, so as to ensure the fluidity of the filter 31, and facilitate rainwater to flow into the storage frame 14 through the filter 31. When the electric push rod 21 is started, it will move with the support block 62, and the support block 62 will move with the bellows 95 and the pull rod 92. The bellows 95 plays a role of auxiliary sealing, and the pull rod 92 will slide in the fixed cylinder 91 in a sealed manner, thereby sucking the hot air in the cab body 1 into the fixed cylinder 91. When the electric push rod 21 resets with the support block 62 and the pull rod 92, the hot air in the fixed cylinder 91 is discharged from the cab body 1 through the exhaust pipe 94. Since the cab body 1 is not completely sealed, external air will continuously enter the cab body 1. At the same time, with the multiple reciprocating movements of the electric push rod 21, the high temperature in the cab body 1 is discharged, and the low temperature from the outside enters the cab body 1. When working outdoors, the high temperature in the cab body 1 is discharged in advance, and the low temperature outside is introduced, so that the refrigeration equipment in the cab body 1 can be quickly cooled, and the working efficiency of the refrigeration equipment is improved. At the same time, the comfort of the staff entering the cab body 1 is also improved.

[0039] Working principle: By starting the water pump in the water storage box 12, the water pump draws the water in the water tank 11 into the water storage box 12 through the water pumping pipe 13, and then the water flows out through the water flow hole at the bottom of the water storage box 12, thereby forming a water curtain at the glass window 3 of the side door 2. Part of the water in the water storage box 12 will enter the atomizing nozzle 19 through the extension pipe 18, and then spray into the cab body 1. The purpose of installing the storage frame 14 on the top of the water storage box 12 is to collect rain when it rains. At the same time, installing the filter 31 in the storage frame 14 can play a role in separating impurities, allowing water to flow into the water storage box 12 through the filter 31, while the impurities are blocked by the filter 31 and guided to the rotating plate 32 by the inclined filter 31. When the accumulated impurities need to be cleaned, the electric push rod 21 is started, and the electric push rod 21 and the scraper 33 are used to push the impurities remaining on the filter screen 31 to move to the rotating plate 32, and the arc-shaped scraper 33 is used to rotate and push the rotating plate 32 toward the direction of the water storage box 12. As the scraper 33 continues to move, the impurities are discharged through the gap between the rotating plate 32 and the storage frame 14. The recovery box 41 is installed below the water storage box 12 to collect the water of the water curtain, so that the water is re-directed back to the water tank 11 through the recovery pipe 42. The baffle 43 and the slide plate 44 are installed on the recovery box 41 to reduce the impact of natural wind on the water curtain. The slide plate 44 can be slid to adjust the height as needed, and the slide plate 44 is fixed in the baffle 43 by bolts 45. By installing a solar panel 16 on the top of the cab body 1, the solar panel 16 absorbs the top solar energy to generate electricity for the water pump in the water storage box 12. When it rains, rainwater will flow into the guide pipe 17 through the guide groove opened on the shell 15, and then enter the storage frame 14 through the guide pipe 17.

[0040] After the electric push rod 21 and the scraper 33 finish cleaning the filter 31, they continue to move toward the back plate 23, and use the push plate 22 to squeeze the storage box 24 on the back plate 23, so that the insect repellent in the storage box 24 is squeezed into the spray pipe 25 and the guide pipe 50 and then sprayed toward the lighting lamp 5, thereby achieving the effect of repelling insects at the lighting lamp 5. At the same time, the output rod of the electric push rod 21 uses the support block 62 in the slide groove 61 to play the role of auxiliary support and sliding when moving. And the support block 62 will squeeze the elastic block 63 in the slide groove 61 when moving, so that the gas in the elastic block 63 is blown toward the lighting lamp 5 and the guide pipe 50 through the outlet pipe 64.

[0041] When the support block 62 moves, it will move with the connecting rod 71, the rectangular rod 72 and the cleaning cloth 73. The rectangular surface of the rectangular rod 72 is used to increase the contact area between the cleaning cloth 73 and the solar panel 16. The rectangular rod 72 cannot rotate, which improves the ability of the cleaning cloth 73 to wipe and clean the surface of the solar panel 16. When the electric push rod 21 brings the support block 62 back to the original position, the support block 62 will also bring the connecting rod 71, the rectangular rod 72 and the cleaning cloth 73 back to the original position. At this time, the rectangular rod 72 enters the groove of the protective cover 75, and the cleaning cloth 73 cooperates to enter the protective cover 75, thereby reducing the contamination of the cleaning cloth 73.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
