[0020] This section is based on Figure 1-9 The working process described is as follows: To prevent the submersible pump from getting stuck when it is submerged into a small-diameter well for pumping water, the main frame 101 has a top pipe for connecting to an external pipeline at its top, and an inlet pipe 102 for drawing water into the main frame 101 is integrally installed on the lower side of the main frame 101. A sub-frame 201 is fixedly connected to the bottom of the main frame 101 by bolts, and a rotatable drill plate 202 is rotatably connected to the bottom of the sub-frame 201. When the main frame 101 and the sub-frame 201 are submerged to the bottom of the water, the drill plate 202 is located on the lower side in the submersion direction. By rotating the drill plate 202, obstacles in the path of movement can be broken or pushed to other positions to prevent them from affecting the further submersion of the entire device to the bottom of the water. This ensures that the submersible pump will not get stuck when it is submerged into a small-diameter well for pumping water, thus improving the submersible pump's submersion efficiency.
[0021] This section is based on Figure 1-9 The working process described is as follows: the drill plate 202 is made of stainless steel, which makes it easier to crush or push away obstacles by using the hardness of the drill plate 202.
[0022] This section is based on Figure 1-9 The working process described is as follows: when the rotation of the drill plate 202 crushes or pushes away the obstruction, the above work is carried out by the circular motion of multiple triangular plates on the drill plate 202.
[0023] This section is based on Figure 1-9 The working process described is as follows: a sharp surface is ground on the outer side of each of the triangular plates to improve the efficiency of breaking obstacles such as stones.
[0024] This section is based on Figure 1-9 The working process described is as follows: when the inlet pipe 102 draws water into the main frame 101 and outputs water through the pipe connected to the upper side of the main frame 101, the water is drawn in through the small holes in the outer circumferential direction of the inlet pipe 102. Furthermore, a filter screen is adhered and installed on the inner layer of the inlet pipe 102 to facilitate the filtration of impurities contained in the water and improve the purity of the extracted water.
[0025] A rotating rod 103 extending into the interior of the main frame 101 is rotatably connected to the middle of the main frame 101. Multiple impellers 106 are evenly fixedly connected to the upper side of the rotating rod 103. A motor 105 is fixedly connected to the bottom of the rotating rod 103. The motor 105 is fixedly connected to the fixing frame 203. The fixing frame 203 is fixedly connected to the interior of the sub-frame 201. The bottom of the rotating rod 103 is rotatably connected to the upper side of the fixing frame 203.
[0026] Gear I 104 is fixedly connected to the lower side of the rotating rod 103.
[0027] This section is based on Figure 1-9 The working process described is as follows: when water is drawn in through the inside of the main frame 101, the motor 105 located on the fixed frame 203 is driven to rotate the rotating rod 103, which is fixedly connected to the output shaft of the motor 103 via a coupling. Furthermore, multiple impellers 106 located on the rotating rod 103 rotate, thereby drawing in water and drawing it out through the external pipe fixed and connected to the upper side of the main frame 101.
[0028] The bottom of the fixed frame 203 is rotatably connected to a bottom rod 204, the bottom of the bottom rod 204 is fixedly connected to the top of the drill plate 202, and a gear II 205 is fixedly connected to the upper side of the bottom rod 204.
[0029] This section is based on Figure 1-9 The working process described is as follows: when the drill plate 202 is rotated, the top of the drill plate 202 is fixedly connected to the bottom rod 204, and the bottom rod 204 is rotatably connected to the bottom of the fixed frame 203. The middle part of the bottom rod 204 is fixedly connected to the gear II 205 by bolts, so that the force of rotating the bottom rod 204 can be transmitted through the gear II 205.
[0030] The gear I104 and the gear II205 are the same size.
[0031] A transmission rod 206 is movably connected to the rear side of the fixed frame 203. The fixed end of an electric push rod 208 is fixedly connected to the rear side of the fixed frame 203. A two-way plate is fixedly connected to the movable end of the electric push rod 208. The rear side of the two-way plate is rotatably connected to the transmission rod 206. A gear III 207 is fixedly connected to the upper and lower sides of the transmission rod 206 respectively. The gear III 207 on the upper side meshes with gear I 104 for transmission, and the gear III 207 on the lower side meshes with gear II 205 for transmission.
[0032] This section is based on Figure 1-9 The working process described is as follows: When the bottom rod 204 rotates synchronously with the rotating rod 103, the electric push rod 208 is driven to move the transmission rod 206 up and down through the bidirectional plate. When the transmission rod 206 descends, the two gears III 207 disengage from gear I 104 and gear II 205 respectively. When pumping water and continuing to make the submersible pump descend, the electric push rod 208 is driven to move the transmission rod 206 up through the bidirectional plate, and the two gears III 207 engage with gear I 104 and gear II 205 respectively, thereby rotating the drill plate 202 and further improving the overall working versatility of the submersible pump.
[0033] The two gears Ⅲ207 are the same size.
[0034] This section is based on Figure 1-9 The working process described is as follows: making the two gears Ⅲ207 the same size so that the force transmitted is the same, and the same principle applies to gear Ⅰ104 and gear Ⅱ205 having the same size.
