DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0021] In one embodiment, see Figure 1 and Figure 2 , an oil depot exhaust device, comprising an oil depot body 1, wherein two relatively distributed side walls of the oil depot body 1 are respectively provided with an air inlet 4 and an air outlet 6, wherein a mesh plate 5 is fixed inside the air inlet 4, and an air outlet duct 7 is fixed inside the air outlet 6, and a negative pressure fan 8 is installed at one end of the air outlet duct 7 close to the inside of the oil depot body 1, and a rotating rod 10 passes through one of the side walls of the oil depot body 1, and the rotating rod 10 is rotatably connected to the side wall of the oil depot body 1, and the rotating rod 10 and the air outlet duct 7 are located on the same side of the oil depot body 1, and the rotating rod 10 is connected to a first blocking mechanism 2 and a second blocking mechanism 3, the first blocking mechanism 2 is used for sealing the air outlet duct 7, and the second blocking mechanism 3 is used for sealing the air inlet 4, and a mounting plate 9 is fixed on the outer wall of the oil depot body 1, and a motor 11 is installed at the bottom of the mounting plate 9, and the output end of the motor 11 is fixedly connected to the end of the rotating rod 10.

[0022] In this embodiment, when the oil depot body 1 is not exhausted, the first blocking mechanism 2 is used to seal the air outlet duct 7, and the second blocking mechanism 3 is used to seal the air inlet 4, thereby playing a sealing role for the entire oil depot body 1, which can effectively prevent impurities in the outside air from entering the oil depot body 1 and affecting the oil body. When the oil depot needs to be exhausted, the motor 11 drives the rotating rod 10 to rotate, and the rotating rod 10 drives the first blocking mechanism 2 and the second blocking mechanism 3 to operate while rotating, thereby releasing the blockage of the air outlet duct 7 by the first blocking mechanism 2, and releasing the blockage of the air inlet 4 by the second blocking mechanism 3, and at the same time starting the negative pressure fan 8, so that the oil depot body 1 is in a ventilated state. Under the action of the negative pressure fan 8, the airflow enters the oil depot body 1 through the air inlet 4, and is then discharged from the air outlet duct 7, thereby taking away the harmful gas inside the oil depot body 1, which can effectively avoid the damage caused to the staff by the harmful gas inside the oil depot body 1. The air outlet duct 7 can be connected to a purification device, and the exhaust gas is purified by the purification device, so as to avoid the exhaust gas being directly discharged into the atmosphere. The purification device is a prior art and will not be described in detail here. In addition, a mesh plate 5 is provided at the air inlet 4, and the air is filtered by the mesh plate 5, which can effectively avoid the phenomenon that impurities in the air enter the oil depot body 1 together with the airflow during the exhaust process.

[0023] See also Figure 2 and Figure 3The first blocking mechanism 2 includes a sealing plate 22 that passes through the top of the air outlet duct 7, and the side wall of the sealing plate 22 is slidably connected to the side wall of the air outlet duct 7, wherein a first winding roller 25 is fixed to the outside of the rotating rod 10, a first traction rope 24 is fixed to the top of the sealing plate 22, and the other end of the first traction rope 24 is fixedly connected to the first winding roller 25, and symmetrically distributed protrusions 23 are fixed to the top of the sealing plate 22, and the bottom of the protrusions 23 are fixed with first elastic components 21, and the lower end of the first elastic component 21 is fixedly connected to the top of the air outlet duct 7;

[0024] When the oil depot body 1 does not need to be vented, the bottom of the sealing plate 22 is tightly fitted with the bottom of the air outlet duct 7 under the action of the first elastic component 21, wherein the first elastic component 21 can be a spring, thereby sealing the air outlet duct 7, effectively preventing impurities in the air from entering the interior of the oil depot body 1 through the air outlet duct 7. When the oil depot body 1 needs to be vented, the motor 11 drives the rotating rod 10 to rotate, and the rotating rod 10 drives the first winding roller 25 to rotate. The first winding roller 25 pulls the sealing plate 22 through the first traction rope 24, thereby causing the sealing plate 22 to move upward, thereby causing the air outlet duct 7 to be in an open state.

[0025] See also Figure 2 and Figure 3 The second blocking mechanism 3 includes a sealing cover 31 arranged inside the oil depot body 1, and the sealing cover 31 is slidably connected to the inner wall of the oil depot body 1, wherein a guide rod 32 is fixed on the top of the sealing cover 31, and a guide cylinder 33 is fixed on the top of the oil depot body 1, and the upper end of the guide rod 32 is inserted into the guide cylinder 33 and slidably connected to the guide cylinder 33, wherein a second elastic component 323 is provided outside the guide rod 32, and the two ends of the second elastic component 323 are respectively fixedly connected to the bottom of the guide cylinder 33 and the top of the sealing cover 31, and one end of the guide rod 32 extending into the guide cylinder 33 is connected to a traction component, and the traction component is used to drive the guide rod 32 to move upward, and a fixing component is provided inside the guide cylinder 33, and when the traction component pulls the guide rod 32 to the highest point, the fixing component is used to fix the guide rod 32;

[0026] When the oil depot body 1 does not need to be vented, the sealing cover 31 seals the air inlet 4 under the action of the second elastic component 323, wherein the second elastic component 323 can be a spring. When the oil depot body 1 needs to be vented, the rotating rod 10 rotates and drives the guide rod 32 to move upward through the traction assembly. The guide rod 32 drives the sealing cover 31 to move upward, thereby releasing the seal of the sealing cover 31 on the air inlet 4, and when the guide rod 32 rises to the highest point, the fixing assembly inside the guide cylinder 33 will automatically fix the guide rod 32, thereby fixing the sealing cover 31, effectively ensuring the stability of the sealing cover 31.

[0027] See also Figure 2 and Figure 3 The traction assembly includes a second traction rope 34 fixed to the top of the guide rod 32, a wire groove is provided at the top of the guide cylinder 33, and the other end of the wire groove passes through the side wall of the guide cylinder 33, a second winding roller 35 is fixed to the outside of the rotating rod 10, and the second traction rope 34 passes through the inside of the wire groove and is fixedly connected to the second winding roller 35, a guide column 36 is fixed to the top of the oil depot body 1, and a guide groove is provided inside the guide column 36, and the two ends of the guide groove respectively pass through the side wall and the bottom of the guide column 36, and the second traction rope 34 passes through the inside of the guide groove;

[0028] When the oil depot body 1 needs to be vented, the motor 11 drives the rotating rod 10 to rotate, and the rotating rod 10 drives the second winding roller 35 to rotate. The second winding roller 35 drives the guide rod 32 to move upward through the second traction rope 34, thereby driving the sealing cover 31 to move upward, and when the guide rod 32 rises to the highest point, the fixing component inside the guide cylinder 33 will automatically fix the guide rod 32, thereby ensuring the stability of the sealing cover 31.

[0029] See also Figure 2 and Figure 3 The fixing assembly includes a pin rod 37 penetrating the side wall of the guide cylinder 33, one end of the pin rod 37 is connected to the side wall of the guide rod 32, and the other end of the pin rod 37 is connected to the outer wall of the guide cylinder 33 through a third elastic component 310, wherein a pin groove 38 adapted to the pin rod 37 is provided on the side wall of the pin rod 37, and the pin rod 37 is fixedly connected to a third traction rope 39, a fixing plate 311 is fixed on the top of the oil depot body 1, a sliding rod 312 is penetrated inside the fixing plate 311, and the sliding rod 312 is slidably connected to the fixing plate 311, one end of the sliding rod 312 is fixedly connected to the third traction rope 39, and the other end of the sliding rod 312 is fixed to a first magnet 313, and a connecting plate 315 is fixed to the outside of the rotating rod 10, and a second magnet 314 is fixed to the side of the connecting plate 315 close to the first magnet 313, and the first magnet 313 and the second magnet 314 have opposite magnetic properties;

[0030] When the guide rod 32 rises to the highest point, the pin rod 37 is aligned with the pin groove 38 on the side wall of the guide rod 32. At this time, under the action of the third elastic component 310, the pin rod 37 automatically enters the pin groove 38. The third elastic component 310 can be a spring. The pin rod 37 plays a fixing role on the guide rod 32 through the pin groove 38. When the oil depot body 1 does not need to be exhausted, the motor 11 drives the rotating rod 10 to reverse, and the rotating rod 10 drives the second winding roller 35 to reverse, so that the second traction rope 34 is in a relaxed state, thereby releasing the traction of the second traction rope 34 on the guide rod 32 When the rotating rod 10 rotates, the connecting plate 315 is also driven to rotate. The connecting plate 315 drives the second magnet 314 to make a circular motion. When the second magnet 314 rotates to the position of the first magnet 313, the second magnet 314 and the first magnet 313 attract each other. The first magnet 313 drives the sliding rod 312 to move horizontally. The sliding rod 312 pulls the pin rod 37 through the third traction rope 39, thereby pulling the pin rod 37 out of the pin groove 38. The pin rod 37 is lost. The sealing cover 31 automatically resets under the action of the second elastic component 323, thereby blocking the air inlet 4.

[0031] See also Figure 2 and Figure 3 The side wall of the sealing cover 31 is provided with an air cavity 321, and a plurality of air blowing pipes 322 are fixed on the inner wall of the sealing cover 31. The air outlet pipe 320 is communicated with the air cavity 321, wherein the air cavity 321 is connected with an inflatable component, and the inflatable component is used to inflate the air cavity 321;

[0032] When the sealing cover 31 is automatically reset, the inflation assembly inflates the air cavity 321, and the gas is discharged from the air blowing pipe 322. Along with the reset of the sealing cover 31, the gas discharged from the air blowing pipe 322 will pass over the surface of the mesh plate 5, and then blow off the impurities adsorbed on the outer surface of the mesh plate 5, which can effectively avoid the phenomenon of impurities blocking the mesh holes, so that when the oil depot is vented next time, the air flow can smoothly pass through the inside of the mesh plate 5, thereby ensuring the circulation of gas and eliminating the need for manual cleaning of the mesh plate 5, saving manpower.

[0033] See also Figure 2 and Figure 3 The inflation assembly includes an air pressure cylinder 316 fixedly connected to the top of the sealing cover 31, an air outlet pipe 320 is connected to the side wall of the air pressure cylinder 316, and the other end of the air outlet pipe 320 is connected to the air cavity 321, wherein a piston 317 is slidably connected to the inside of the air pressure cylinder 316, and a support rod 318 is fixedly connected to the piston 317, and a support plate 319 is fixedly connected to the inner wall of the oil depot body 1, and the top of the support plate 319 is fixedly connected to the bottom of the support rod 318;

[0034] When the sealing cover 31 moves downward, it also drives the air cylinder 316 to move downward. When the air cylinder 316 moves downward, the support rod 318 squeezes the gas inside the air cylinder 316 through the piston 317, so that the gas inside the air cylinder 316 can enter the air cavity 321 through the air outlet pipe 320, thereby cleaning the outside of the mesh plate 5.

[0035] Working principle: When the oil depot body 1 is not exhausting, the sealing plate 22 blocks the air outlet duct 7, and the sealing cover 31 blocks the air inlet 4, thereby sealing the entire oil depot body 1, which can effectively prevent impurities in the outside air from entering the oil depot body 1 and affecting the oil body. When the oil depot needs to be exhausted, the motor 11 drives the rotating rod 10 to rotate, and the rotating rod 10 drives the first winding roller 25 and the second winding roller 35 to rotate at the same time. The first winding roller 25 pulls the sealing plate 22 through the first traction rope 24, so that the sealing plate 22 moves upward, thereby opening the air outlet duct 7, and the second winding roller 35 drives the guide rod 32 to move upward through the second traction rope 34, thereby driving the sealing cover 3 1 moves upward, so that the air inlet 4 is in an open state, and the negative pressure fan 8 is started at the same time. Under the action of the negative pressure fan 8, the air flow enters the oil depot body 1 through the air inlet 4, and is then discharged from the air outlet duct 7, thereby taking away the harmful gas inside the oil depot body 1, which can effectively avoid the damage to the staff caused by the harmful gas inside the oil depot body 1. When the guide rod 32 rises to the highest point, the pin rod 37 automatically enters the pin groove 38, and the pin rod 37 plays a fixing role on the guide rod 32 through the pin groove 38. When the oil depot body 1 does not need to be exhausted, the motor 11 drives the rotating rod 10 to reverse, and the rotating rod 10 drives the first winding roller 25 and the second winding roller 35 to reverse, and the first winding roller 25 no longer passes through the first traction rope 24 to seal The plate 22 is pulled by the rope, and the sealing plate 22 is automatically reset to block the air outlet duct 7. At the same time, the second winding roller 35 no longer pulls the guide rod 32 through the second traction rope 34. The second traction rope 34 is in a relaxed state. When the rotating rod 10 rotates, the connecting plate 315 is also driven to rotate. The connecting plate 315 drives the second magnet 314 to make a circular motion. When the second magnet 314 rotates to the position of the first magnet 313, the second magnet 314 and the first magnet 313 attract each other. The first magnet 313 drives the sliding rod 312 to move horizontally. The sliding rod 312 pulls the pin rod 37 through the third traction rope 39, thereby pulling the pin rod 37 out of the pin groove 38. The pin rod 37 is lost. The sealing cover 31 is automatically reset to block the air inlet 4. The air cylinder 316 is sealed by the air outlet pipe 320. In addition, the sealing cover 31 automatically resets and drives the air cylinder 316 to move downward. When the air cylinder 316 moves downward, the support rod 318 squeezes the gas inside the air cylinder 316 through the piston 317, so that the gas inside the air cylinder 316 can enter the air cavity 321 through the air outlet pipe 320, and finally be discharged from the air blowing pipe 322. Along with the resetting of the sealing cover 31, the gas discharged from the air blowing pipe 322 will pass over the surface of the mesh plate 5, and then blow off the impurities adsorbed on the outer surface of the mesh plate 5, which can effectively avoid the phenomenon of impurities blocking the mesh holes, so that the oil depot can smoothly pass through the inside of the mesh plate 5 when exhausting the gas next time, thereby ensuring the circulation of gas and eliminating the need for manual cleaning of the mesh plate 5, saving manpower.
