DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-10 , the present invention provides a technical solution:

[0035] See also Figure 1-3 A snow and frost proof container generator set, comprising a container 1 and a generator set 2 arranged in the container 1, an air inlet device 3 is arranged on the container 1, the air inlet device 3 comprises a frame 4, a plurality of ventilation windows 5 are arranged on the frame 4 in a height direction, one side of the ventilation window 5 is horizontally opened toward the outside of the container 1, and the other side of the ventilation window 5 is inclined upward toward the inside of the container 1, a filter screen 6 is arranged at one end of the ventilation window 5 located outside the container 1, and an automatic cleaning mechanism 7 is arranged in each ventilation window 5;

[0036] See also Figure 3 , 4 , 5. A water collecting trough 8 is provided at the bottom of the ventilation window 5. The automatic cleaning mechanism 7 includes a balance plate 71, a scraper assembly 72 and a tension assembly 73. Rotary holes 9 are provided on the front and rear sides of the water collecting trough 8. A rotating shaft 10 is provided on the front and rear sides of the balance plate 71 to form a rotation connection with the rotating hole 9. The balance plate 71 is arranged in the water collecting trough 8 through the cooperation and rotation of the rotating shaft 10 and the rotating hole 9. A balancing spring 11 is connected between the two sides of the bottom of the balancing plate 71 and the inner wall of the bottom of the water collecting trough 8. In the initial state, the balancing plate 71 is kept in a horizontal state by the balancing spring 11. The scraper assembly 72 includes a scraper 721 and a tension wheel 722. A slider groove 12 is provided at the bottom of the scraper 721. A hinge block 13 is provided in the slider groove 12 to slide up and down, and a compression spring 14 is provided on the inner wall at the top of the slider groove 12 to drive the hinge block 13 to slide toward one side of the balance plate 71. The tension wheel 722 is rotatably arranged at the bottom of the hinge block 13 The bottom of the balance plate 721 is against the top end surface of the balance plate 71. When the balance plate 71 rotates and tilts, the tension wheel 722 will slide toward the lower tilted side of the balance plate 71 under the action of the compression spring 14 pressing the hinge block 13 downward, thereby driving the scraper 721 to slide so that the scraper 721 cleans the snow, water and dust on the inner wall of the ventilation window 5 (in heavy snowy weather, when the ventilation window 5 is blown in, the snow will pass through the filter 6 and stagnate in the water collecting tank 8 of the ventilation window 5. When the engine unit is running, the temperature in the container 1 will rise and melt the snow. The water formed after the snow melts will become the water for the scraper 721 to clean the ventilation window 5). The vertical section of the scraper 721 is matched with the cross-section of the ventilation window 5, so that the scraper 721 can scrape off the dust on the inner wall of the ventilation window 5 when sliding. A stabilizing block 40 is set on the top of the scraper 721, and a stabilizing groove 41 for the stabilizing block 40 to slide is set on the inner wall of the top of the ventilation window 5.

[0037] See also Figure 6 , 78, cavities 15 are symmetrically arranged on both sides of the ventilation window 5 in the frame 4, the tension component 73 includes a pull rope 731 and a water collecting box, and connecting ports 16 are arranged on both sides of the water collecting tank 8 and connected to the cavity 15, and water outlet pipes 17 are symmetrically arranged at both ends of the balance plate 71, one end of the water outlet pipe 17 extends into the cavity 15 through the connecting port 16 and opens toward the water collecting box 732, wherein a thin rubber 18 can be arranged in the connecting port 16 to form a sealing protection for the connecting port 16 (without affecting the water outlet pipe 17 to follow the swing of the balance plate 71), and the scraper 721 blocks one side of the water outlet pipe 17 in the initial state, and when there is water in the water collecting tank 8, the water will be connected to the unblocked side. The water flows from the outlet 16 to the water collecting box 732 in the cavity 15. The outlet pipe 17 is located at the top of one end in the cavity 15 and is rotatably provided with a first wire wheel 19. The pull rope 731 is connected to the water collecting box after passing through the first wire wheel 19. After the water collecting box 732 collects a certain amount of water, the water collecting box will slide down and drive one side of the balance plate 71 to descend and rotate. After the balance plate 71 rotates, it will tilt. Under the action of the compression spring 14 pressing the hinge block 13 downward, the tension wheel 722 will slide toward the lower tilted side of the balance plate 71, thereby driving the scraper 721 to slide so that the scraper 721 can clean the snow, water and dust on the inner wall of the ventilation window 5.

[0038] See also Figure 8-10 , in order to make the scraper 721 start to slide to the other side after the water collecting box 732 collects a certain amount of water, a first magnetic attraction 20 is provided on the end surface of the side where the water outlet pipes 17 on both sides are close to each other, and the end surfaces of the scraper 721 on both sides are respectively provided with second magnetic attractions 21 attracted to the first magnetic attractions 20 on both sides, and the pull rope 731 is provided with a stopper 22 on both sides of the ventilation window 5 for driving the scraper 721 to move toward the opposite side, and the scraper 721 is slidably sleeved on the pull rope 731, and the water collecting box is slidably arranged in the cavity 15 up and down, and the two ends of the pull rope 731 are respectively connected to the water collecting boxes located in the cavities 15 on both sides. After the water collecting box starts to collect some water, it will slide downward for a distance and drive the balance plate 71 to rotate, and the balance plate 71 will rotate when the first magnetic attraction 2 0 and the second magnetic attraction 21, the scraper 721 still keeps blocking the water outlet pipe 17 on one side without moving. After the water collecting box 732 collects more water and continues to increase its weight, it will pull the pull rope 731 to move, thereby driving the stopper 22 to move. The stopper 22 will push the scraper 721 to move. The scraper 721 will obtain an initial speed and move toward the other side of the ventilation window 5 under the action of the compression spring 14 and the hinge block 13 until the opening of the water outlet pipe 17 on the other side is blocked, so that the water in the water collecting tank 8 will flow into the water collecting box 732 in the cavity 15 on the opposite side of the scraper 721, so that after a period of time, the scraper 721 will move to the other side again to achieve reciprocating cleaning of the ventilation window 5.

[0039] See also Figure 4-7Since the balance plate 71 is tilted when the scraper 721 moves in the ventilation window 5, in order to enable the scraper 721 to better push water into the water collecting box 732 during the sliding process, gravity plates 23 are symmetrically arranged on both sides of the scraper 721, and side grooves 24 are arranged on the scraper 721 for the gravity plate 23 to slide up and down. During the horizontal movement of the scraper 721, the gravity plate 23 will continue to move downward under the action of gravity so that it can fit the balance plate 71. The first magnetic attraction 20 will be arranged on the gravity plate 23, and limit bars 26 are also arranged on both sides of the gravity plate 23. Limit grooves 25 for the limit bars 26 to slide are arranged on the side walls of the side grooves 24, which can prevent the gravity plate 23 from separating from the scraper 721 when sliding.

[0040] See also Figure 3 , 5 A brush roller 27 is provided on one side of the scraper 721 close to the filter screen 6 , and the outer side of the brush roller 27 abuts against the filter screen 6 . When the scraper 721 moves, the filter screen 6 can also be cleaned by the brush roller 27 .

[0041] See also Figure 8-10 In order to make the water in each group of ventilation windows 5 flow better into the water collecting box 732, a plurality of auxiliary water collecting boxes 28 are provided in the cavity 15 along the height direction corresponding to the number of ventilation windows 5. The water collecting box 732 is located at the lowest end of all the auxiliary water collecting boxes 28. The auxiliary water collecting boxes 28 are all slidably arranged on the inner wall of the cavity 15, and a connecting rope 29 is connected between the inner wall of one side and the stretching. The water outlet pipe 17 on one side of each group of balance plates 71 is corresponding to a group of auxiliary water collecting boxes 28. The bottom end surface of each group of auxiliary water collecting boxes 28 is provided with a water guide pipe 30, and the bottom end of the water guide pipe 30 extends into the next auxiliary water collecting box 28. Through the action of the auxiliary water collecting boxes 28 and the water guide pipe 30, it is ensured that the water flows stably into the water collecting box 732 at the lowest end, and the auxiliary water collecting boxes 28 are connected to the stretching through the connecting rope 29, so that all the auxiliary water collecting boxes 28 can move up and down more stably and drive the scraper 721 to slide through the pull rope 731. It should be noted that: all the pull ropes 731 and the connecting ropes 29 are connected to a main rope 31, and the bottom end of the main rope 31 is connected to the water collecting box 732. The water pipe 30 extends to one end of the auxiliary water collecting box 28 and is connected to the inner wall of the auxiliary water collecting box 28 with a connecting rib 32, so that all the auxiliary water collecting boxes 28 and the water collecting box 732 are fixed as a whole, and the auxiliary water collecting box 28 or the water collecting box 732 can move up and down together, so that the scraper 721 can slide back and forth regularly in the ventilation window 5. It should be noted that: a T-block 33 is provided on one side of the auxiliary water collecting box 28, and a T-slot 34 is provided on the inner wall of the cavity 15 for the T-block 33 to move up and down. The auxiliary water collecting box 28 can stably move up and down in the cavity 15 through the cooperation of the T-block 33 and the T-slot 34.

[0042] See also Figure 8A plurality of second guide wheels 35 are provided in the cavity 15 along the height direction corresponding to the number of auxiliary water collecting boxes 28. One end of each pull rope 731 located in the cavity 15 passes through the second guide wheel 35 and is connected to the main rope 31. The setting of the first guide wheel 19 and the second guide wheel 35 ensures that the main rope 31 and the connecting rope 29 are stably stretched.

[0043] See also Figure 8-10 In order to ensure that the scraper 721 can continue to slide back after sliding from one side of the ventilation window 5 to the other side, the water circulation of the water collecting box 732 in the cavities 15 on both sides is switched from a water-containing state to a water-free state in turn when necessary, so that the balance plate 71 can switch the tilt direction cyclically, a docking hole 36 is provided at the bottom of the cavity 15, a water passing component 39 is provided in the docking hole 36, the docking hole 36 is connected to the outside and a water outlet channel 37 is provided, and a docking pipe 38 docking with the docking hole 36 is provided at the bottom of the water collecting box 732, wherein the water passing component 39 includes a support spring 391 and a baffle 392, one end of the water outlet channel 37 is connected to the docking hole 36, and the other end is connected to the outer end of the frame 4 Connected, in the initial state, the baffle 392 is located above the opening of the water outlet channel 37 under the action of the support spring 391, and the water in the water collecting box 732 cannot flow out. After the scraper 721 moves to the side of the water collecting box 732 that collects water, the amount of water in the water collecting box 732 will be able to drive the water collecting box 732 to move downward, so that the docking tube 38 presses down the baffle 392, so that the baffle 392 is located below the water outlet channel 37. At this time, the water in the water collecting box 732 will be able to flow from the water outlet channel 37 to the outside of the frame 4, thereby discharging the water (in order to avoid the baffle 392 blocking the opening of the docking tube 38, an opening can be set on the side wall of the docking tube 38 to ensure that the water can flow out smoothly).

[0044] See also Figure 1-10 When the device is in use, in order to reduce the preheating time of the generator set 2 when used in cold weather, a space heater can be used to maintain a suitable temperature in the container 1 (the space heater is a prior art).

[0045] When the container 1 is ventilated for a long time through the ventilation window 5, dust and rain and snow will adhere to the ventilation window 5. Under the guidance of the water collecting tank 8, water will flow into the auxiliary water collecting box 28 in the cavity 15 through the water outlet pipe 17 at one end of the balance plate 71, and finally flow into the water collecting box 732 at the bottom through the water guide pipe 30. When the water in the water collecting box 732 increases, the water collecting box 732 will slide downward for a distance and pull down one side of the balance plate 71 through the pull rope 731, so that the balance plate 71 rotates and tilts. After the water in the water collecting box 732 continues to increase, , the water collecting box 732 will continue to slide downward for a distance and pull the pull rope 731, the stopper 22 on the pull rope 731 will pull the scraper 721, and the first magnetic attraction 20 on the scraper 721 will be separated from the second magnetic attraction 21. Under the action of the compression spring 14 and the hinge block 13, the scraper 721 will slide on the balance plate 71 toward the lower inclined side through the guide wheel, thereby scraping off the dust in the ventilation window 5 and the dust on the filter 6. At the same time, under the action of the gravity plate 23, the dust in the water collecting tank 8 will be scraped to the lower inclined side of the balance plate 71. The dust and water will eventually flow into the water collecting box 732. After the scraper 721 moves to the first magnetic attraction 20 and fits the second magnetic attraction 21 on the lower side of the balance plate 71, the water outlet pipe 17 will be blocked. After the water in the water collecting tank 8 continues to increase, it will flow toward the water collecting box 732 in the cavity 15 on the other side. At the same time, the docking pipe 38 at the bottom end of the water collecting box 732 corresponding to the side blocked by the scraper 721 will press down the baffle 392 in the docking hole 36, so that the baffle 392 moves to the lower end of the opening of the water outlet channel 37, and the water in the water collecting box 732 will flow through the water outlet channel 3 7 flows out, and at this time, the water collecting box 732 on the other side collects the water flowing out of the water collecting tank 8, making the weight of the water collecting box 732 on the other side heavier, until the balance plate 71 rotates again, making the side with a higher inclination become the side with a lower inclination. According to the above method, after the water collecting box 732 receives a certain amount of water, the scraper 721 will slide to the opposite side of the ventilation window 5, thereby realizing the cyclic sliding of the scraper 721, and cleaning and dehydrating the ventilation window 5 without driving equipment and manual intervention, to prevent dust and water from entering the container 1 during the ventilation process of the container 1.
