Specific embodiments

[0021] The technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. In addition, the forms of the various structures described in the following embodiments are merely examples, and the present utility model is not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0022] Refer to Figures 1 - 5 , the present utility model provides a soft start control box for a submersible pump, including an outer shell 1. An outward-opening door 3 is hinged to one side of the outer shell 1. An air outlet is provided on one side of the outer shell 1. An exhaust fan 5 is fixed in the air outlet by bolts. A box body 8 for placing desiccant is fixed to the outer wall of one side of the outer shell 1 by bolts. A plurality of aligned ventilation slots 7 are provided on both sides of the box body 8 and one side of the outer shell 1. A U-shaped frame is fixed to the outer wall of one side of the box body 8 by bolts. Installation grooves 11 are provided on multiple sides of the U-shaped frame. A plastic filter screen 9 for filtering air is inserted into the installation grooves 11. A scraping component for cleaning the plastic filter screen 9 is provided on one side of the U-shaped frame. The box body 8 has an open structure on one side. A door plate assembly for blocking the opening is provided on one side of the box body 8. When the exhaust fan 5 is started, the exhaust fan 5 will extract the air inside the outer shell 1 and discharge the air out of the outer shell 1. While the exhaust fan 5 extracts the air inside the outer shell 1, it will extract the external air through the ventilation slots 7, so that the external air enters the outer shell 1 through the ventilation slots 7. The plastic filter screen 9 will filter the impurities in the air entering the outer shell 1, thereby realizing the air circulation inside the outer shell 1. The plastic filter screen 9 will not affect the air circulation. At the same time, under the action of the suction force of the exhaust fan 5, the air circulation inside the outer shell 1 can be accelerated, so that the heat dissipation inside the control box will not be affected, and the heat dissipation effect of the control box is improved.

[0023] In the present utility model, the door panel assembly includes a blocking door 14 which is rotatably connected to the inside of the box body 8. An elastic buckle 13 is welded to the top of the blocking door 14. Two clamping grooves 16 are formed in the top outer wall of the box body 8, and the elastic buckle 13 is clamped with the clamping grooves 16. Two symmetrically distributed side baffles 15 are welded to one side of the blocking door 14. Arc-shaped limiting grooves 12 are formed in the sides of the two side baffles 15 facing away from each other. Blocking columns 17 are welded to the inner walls of both sides of the box body 8, and the blocking columns 17 are slidably connected with the arc-shaped limiting grooves 12 to limit the blocking door 14. Pull the elastic buckle 13 to deform it, so that the elastic buckle 13 is separated from the clamping groove 16. At this time, the blocking door 14 can be rotated and opened. Then, the whole desiccant is placed into the box body 8. Subsequently, rotate and close the blocking door 14, and make the elastic buckle 13 snap into the clamping groove 16 to fix the blocking door 14. Since the volume of the whole desiccant is larger than the width of the ventilation slot 7, the desiccant will not fall out of the box body 8. When the external air enters the outer shell 1, it will first pass through the box body 8. At this time, the desiccant in the box body 8 will adsorb the moisture in the air, so that the air entering the inner part of the outer shell 1 is in a dry state, avoiding damage to the control box caused by moisture carried in the air. During the process of opening the blocking door 14, the blocking column 17 will move relative to the side baffle 15 in the arc-shaped limiting groove 12. When the blocking column 17 moves to the end of the arc-shaped limiting groove 12, the blocking door 14 cannot be rotated continuously, thus realizing the limit of the rotation of the blocking door 14;

[0024] The scraping component is a scraping box 10 which is fixed to the position at the top of the outer wall of one side of the box body 8 by bolts. A scraping opening 18 is arranged on one side of the top of the scraping box 10. When the plastic filter screen 9 is used for a long time, pull out the plastic filter screen 9 from the installation groove 11 and bend the plastic filter screen 9 to fit with the scraping opening 18 on the scraping box 10. At this time, the scraping opening 18 will scrape and clean the dust and impurities on the plastic filter screen 9, so that the dust and impurities fall into the scraping box 10. A temperature sensor 2 for detecting the temperature inside the outer shell 1 is fixed to one side of the outer door 3 by bolts. Two symmetrically distributed fixing holes 4 are formed in the positions at the top and bottom of one side of the outer shell 1. Two wire protecting sleeves 6 are arranged on the bottom outer wall of the outer shell 1.

[0025] Working principle of the present utility model: Start the exhaust fan 5. The exhaust fan 5 will extract the air inside the housing 1 and discharge the air out of the housing 1. While extracting the air inside the housing 1, the exhaust fan 5 will extract the external air through the ventilation slots 7, so that the external air enters the housing 1 through the ventilation slots 7. The plastic filter screen 9 will filter the impurities in the air entering the housing 1, thereby realizing the air circulation inside the housing 1. The plastic filter screen 9 will not affect the air circulation. At the same time, under the action of the suction force of the exhaust fan 5, the air circulation inside the housing 1 can be accelerated, so that it will not affect the heat dissipation inside the control box, improving the heat dissipation effect of the control box. Pull the elastic buckle 13 to deform, so that the elastic buckle 13 is disengaged from the card slot 16. At this time, the blocking door 14 can be rotated and opened. Then, the bulk desiccant is put into the box body 8. Subsequently, the blocking door 14 is rotated and closed, and the elastic buckle 13 is snapped into the card slot 16 to fix the blocking door 14. Since the volume of the bulk desiccant is larger than the width of the ventilation slot 7, the desiccant will not fall out of the box body 8. When the external air enters the housing 1, it will first pass through the box body 8. At this time, the desiccant in the box body 8 will adsorb the moisture in the air, so that the air entering the inside of the housing 1 is in a dry state, avoiding damage to the control box caused by moisture carried in the air.

It can be directly connected. "Up", "down", "left", "right", etc. are only used to represent the relative position relationship.
