[0018] Compared with the prior art, the advantages and positive effects of the present invention are:

[0019] 1. When the present invention is in use, the bottom of the water inlet pipe contacts the sewage. At this time, the external power supply of the bidirectional motor is controlled, and then the output shaft of the bidirectional motor drives the first rotating shaft to rotate, and further the gear rotates. The kit has a fixing effect on the gear, so that the gear is installed on the outer surface of the first rotating shaft, and the rack moves by meshing. When the gear rotates in different directions, the rack moves up and down differently, so that the rack drives the circular plate to move upward through the bottom rod. There is no gap between the circular plate and the inner wall of the collecting dish. When the circular plate moves upward, it has a suction effect on the sewage, so that the sewage passes through the water inlet pipe and enters the interior of the collecting dish, thereby completing the collection of the sewage. In the process of sucking up the sewage, the multiple small holes on the filter plate allow the sewage to enter the interior of the collecting dish, and the floating objects in the sewage can be blocked to prevent the floating objects in the sewage from entering the collecting dish. The inside of the collection dish affects the detection of sewage. The sewage is placed inside the collection dish through the generated air pressure difference. The rotation of the control gear is controlled so that the circular plate pushes the sewage inside the collection dish to be discharged. At this time, the handle can be controlled to rotate the second rotating shaft. The handle makes it easy for the second rotating shaft to rotate. The multiple support rods have a supporting effect on the second rotating shaft, and can rotate due to the effect of the bearing, so that the multiple cleaning brushes can rotate. The bristles on the multiple cleaning brushes are close to the bottom of the filter plate, which can prevent floating objects from blocking the small holes of the filter plate and affecting the collection of sewage. The filter plate is fixed to the inside of the water inlet pipe through two fixings, so that the collection of sewage is convenient and simple, and the practicability of the collector is improved. In the process of transporting sewage, the generated air pressure difference can prevent sewage from leaking, and by filtering floating objects in the sewage, it does not affect the later detection of sewage.

[0020] 2. When the present invention needs to collect sewage at different depths, the structure inside the sleeve can complete the collection of sewage at different water level depths. By controlling the switch of the small air pump, the airbag can be inflated or exhausted. When the airbag is inflated, the gas comes into the airbag through the trachea, the airbag will expand, and then the pressure plate will move downward. When the pressure plate moves downward, it will push the elastic member to move downward, and further the collection dish will move downward through the slide bar, thereby completing the collection of sewage at different depths. The switch of the small air pump is controlled to discharge the gas inside the airbag. When the gas inside the airbag is discharged, one side of the elastic member presses against the bottom inner wall of the sleeve, and one side of the pressure plate on the other side will generate elastic force when the elasticity is squeezed, and then the elastic force generated by the elastic member causes the pressure plate to move upward back to its original position, and further the collection dish is returned to its original position through the slide bar. The two support rods have a supporting and fixing function on the annular member and the sleeve. The sleeve can rotate at the bottom of the annular member, and the collection dish is moved downward through the slide bar, thereby completing the collection of sewage at different depths and improving the diversity of the device.

[0021] 3. When the collecting dish needs to be put away, the external power switch of the driving motor is turned on. The rotating rod can rotate due to the action of the bearing, and its output shaft drives the rotating rod to rotate. The two ring sleeves clamp and fix the reel, thereby further rotating the reel. When the reel rotates, the rope will be wound around the outer surface of the reel, and the other end of the rope will pull the sleeve through the transmission member. The sleeve can rotate at the bottom of the ring member, so that the collecting dish is stored inside the storage box, thereby facilitating the storage of the collecting dish and improving the practicality of the device.

[0037] When in use, the bottom of the water inlet pipe 2 is in contact with sewage. At this time, the external power supply of the bidirectional motor 206 is controlled. The two L-shaped rods 205 support the bidirectional motor 206, so that the bidirectional motor 206 is installed inside the collection dish 1. Then, the output shaft of the bidirectional motor 206 drives the first rotating shaft 207 to rotate, and further rotates the gear 208.

The bristles on the multiple cleaning brushes 210 are close to the bottom of the filter plate 209, which can prevent floating objects from blocking the small holes of the filter plate 209 and affecting the collection of sewage. The filter plate 209 is fixed inside the water inlet pipe 2 through two fixing parts 201, so that the collection of sewage is convenient and simple, and the practicality of the collector is improved. In the process of transporting sewage, the air pressure difference can prevent sewage from leaking, and by filtering the floating objects in the sewage, it will not affect the later detection of sewage.

[0038] In one embodiment, the two fixing members 201 are respectively interference fit with the two limiting holes of the water inlet pipe 2. The two fixing members 201 are telescopically inserted into the small holes on the water inlet pipe 2, so that the two fixing members 201 respectively clamp the two sides of the filter plate 209, thereby fixing the filter plate 209. In the process of sucking up sewage, the multiple small holes on the filter plate 209 allow the sewage to enter the interior of the collection dish 1, and the floating objects in the sewage can be blocked, preventing the floating objects in the sewage from entering the interior of the collection dish 1, thereby affecting the detection of the sewage.

[0043] See also Figure 1 , Figure 2 and Figure 3 In another embodiment, a body 5 is provided on the top of the storage box 4. By installing the storage box 4 at the bottom of the body 5, the storage box 4 is brought to the sewage ground where it needs to be collected through the body 5, thereby controlling the collection of the sewage.

[0044] Working principle: When sewage needs to be collected, the bottom of the water inlet pipe 2 is made to contact the sewage. At this time, the external power supply of the two-way motor 206 is controlled, and the two L-shaped rods 205 have a supporting effect on the two-way motor 206, so that the two-way motor 206 is installed inside the collection dish 1, and then the output shaft of the two-way motor 206 drives the first rotating shaft 207 to rotate, and further rotates the gear 208. The kit 213 has a fixing effect on the gear 208, so that the gear 208 is installed on the outer surface of the first rotating shaft 207, and the rack 204 is moved by meshing. When the gear 208 rotates in different directions, the rack 204 moves up and down differently, so that the rack 204 drives the circular plate 202 to move upward through the bottom rod 203, and the circular plate 2 02 and the inner wall of the collection dish 1. When the circular plate 202 moves upward, it has a suction effect on the sewage, so that the sewage passes through the water inlet pipe 2 and enters the interior of the collection dish 1, thereby completing the collection of the sewage. In the process of sucking up the sewage, the multiple small holes on the filter plate 209 allow the sewage to enter the interior of the collection dish 1, and the floating objects in the sewage can be blocked to prevent the floating objects in the sewage from entering the interior of the collection dish 1, thereby affecting the detection of the sewage. The sewage is placed in the interior of the collection dish 1 by the generated air pressure difference. When the gear 208 is controlled to rotate, the circular plate 202 pushes the sewage in the collection dish 1 to be discharged. At this time, the handle 214 can be controlled to rotate the second rotating shaft 212, and the handle 214 causes the second rotating shaft 212 to rotate. The shaft 212 is easy to rotate, and the multiple support rods 211 have a supporting effect on the second rotating shaft 212, and can rotate due to the effect of the bearing, so that the multiple cleaning brushes 210 can rotate. The bristles on the multiple cleaning brushes 210 are close to the bottom of the filter plate 209, which can prevent floating objects from blocking the small holes of the filter plate 209 and affecting the collection of sewage. The filter plate 209 is fixed inside the water inlet pipe 2 through two fixing members 201, so that the collection of sewage is convenient and simple, and the practicality of the collector is improved. In the process of transporting sewage, the pressure difference generated can prevent sewage from leaking, and by filtering the floating objects in the sewage, it does not affect the later detection of sewage. When it is necessary to collect sewage at different depths, the structure inside the sleeve 3 can To complete the collection of sewage at different water depths, the airbag 306 can be inflated or exhausted by controlling the switch of the small air pump 302. When the airbag 306 is inflated, the gas passes through the air pipe 301 and enters the airbag 306, and the airbag 306 will expand, thereby causing the pressure plate 307 to move downward. When the pressure plate 307 moves downward, it will push the elastic member 308 to move downward, and further move the collection dish 1 downward through the slide bar 305, thereby completing the collection of sewage at different depths. The switch of the small air pump 302 is controlled to discharge the gas inside the airbag 306. When the gas inside the airbag 306 is discharged, one side of the elastic member 308 presses against the bottom inner wall of the sleeve 3, and one side of the pressure plate 307 on the other side will generate elastic force when the elasticity is squeezed.Then, the elastic force generated by the elastic member 308 causes the pressing plate 307 to move upward and return to its original position, and further the collecting dish 1 is returned to its original position through the sliding rod 305. The two supporting rods 303 have a supporting and fixing effect on the annular member 304 and the sleeve 3. The sleeve 3 can rotate at the bottom of the annular member 304, and the collecting dish 1 is moved downward through the sliding rod 305, thereby completing the sewage collection at different depths and improving the diversity of the device. When the collecting dish 1 needs to be put away, the external power switch of the driving motor 404 is turned on, and the rotating rod 407 is rotated because of the shaft The bearing can rotate, and its output shaft drives the rotating rod 407 to rotate. The two ring sleeves 406 clamp and fix the wire reel 403, further making the wire reel 403 rotate. When the wire reel 403 rotates, the rope 401 will be wound around the outer surface of the wire reel 403, and the other end of the rope 401 will pull the sleeve 3 through the transmission member 402. The sleeve 3 can rotate at the bottom of the ring member 304, so that the collection dish 1 can be stored inside the storage box 4, so that the collection dish 1 is convenient to store, and the practicality of the device is improved.
