[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0030] Embodiment 1

[0031] A sewage extraction device for water quality detection, as Figures 1 to 6 shown, includes a floating board 1, a floating frame 2, a floating ring 3, an airbag 4, a descending mechanism 11 and a sampling mechanism 12. There are 3 floating frames 2 provided on the top of the floating board 1. A floating ring 3 is connected between the tops of the floating frames 2. A plurality of airbags 4 are provided at the bottom of the floating board 1. An air inlet hole 5 is opened at the top of the airbag 4. A descending mechanism 11 is provided at the bottom of the floating ring 3. A sampling mechanism 12 is placed on the descending mechanism 11.

[0032] The descending mechanism 11 includes a first descending plate 111, a second descending plate 112, a third descending plate 113 and a clamping plate 114. The first descending plates 111 are symmetrically provided at the front and rear of the bottom of the floating ring 3. The second descending plate 112 is slidably provided at the bottom of the first descending plate 111. The third descending plate 113 is slidably provided at the bottom of the second descending plate 112. Clamping plates 114 are provided on the inner sides of the lower parts of the first descending plate 111, the second descending plate 112 and the third descending plate 113.

[0033] The sampling mechanism 12 includes a sampling box 121, a lid 122, a partition plate 124, a partition rack 125 and a partition cap 126. The sampling box 121 is placed between the clamping plates 114 on the same side horizontally. The lid 122 is placed on the top of the sampling box 121 in a threaded manner. Water inlets 123 are opened on the front sides of the sampling boxes 121. A partition plate 124 is connected between the inner walls of the sampling box 121. Small holes are opened on the partition plate 124. A partition rack 125 is arranged at the rear side of the partition plate 124. A partition cap 126 is rotatably arranged on the partition rack 125. An elastic member is arranged between the partition cap 126 and the partition rack 125. The partition cap 126 is slidably connected to the small opening.

[0034] The staff can put the device into the water surface to be detected. The airbag 4 can drive the components above the floating plate 1 to float on the water surface. The second lowering plate 112 and the third lowering plate 113 automatically move downward. Through the clamping plates 114, the two sampling boxes 121 on the lower side are driven to move downward. During the lowering process, the sewage flows into the sampling box 121 through the water inlets 123. Subsequently, the partition cap 126 is washed open and flows into the right side of the partition plate 124. At this time, the elastic member deforms. When the sampling box 121 finishes descending and stops moving, there is sufficient sewage in the partition plate 124. At this time, the elastic member rebounds, and the partition cap 126 automatically blocks the small holes. Sewage at different heights can enter the sampling box 121, ensuring the accuracy of sampling. After sampling, push the floating plate 1 to drive the components below it out of the water surface, take out the sampling box 121, rotate the lid 122 to separate from the sampling box 121, collect the sewage separately, and cooperate with the later detection. After collection, place the device on the ground, and the third lowering plate 113 and the second lowering plate 112 move upward under force for recycling.

[0035] Embodiment 2

[0036] On the basis of Embodiment 1, as Figure 8 and Figure 9 shown, it further includes a control mechanism 14. The control mechanism 14 includes a mounting table 141, a servo motor 142, a first gear 143, a second gear 144, a guide plate 145, a rotating rod 146, a baffle 147, a first spring 148 and a third gear 149. A mounting table 141 is arranged on the top of the right floating frame 2. A servo motor 142 is arranged on the top of the mounting table 141. A first gear 143 is arranged on the output shaft of the servo motor 142. A second gear 144 is rotatably arranged on the top of the floating ring 3. The second gear 144 meshes with the first gear 143. A guide plate 145 is connected to the middle of the first lowering plate 111. Rotating rods 146 are rotatably arranged on the front and rear sides of the top of the floating ring 3. The rotating rods 146 are rotatably connected to the guide plate 145, and a first spring 148 is connected between the top of the rotating rods 146 and the guide plate 145. A third gear 149 is arranged on the top of the rotating rod 146. The third gear 149 meshes with the second gear 144. A baffle 147 is arranged at the bottom of the rotating rod 146. The baffle 147 cooperates with the third lowering plate 113.

[0037] In the initial state, the baffle 147 blocks the third descending plate 113, and the third descending plate 113 will not move downward automatically. When the device is in water, the servo motor 142 is started. The output shaft of the servo motor 142 rotates to drive the second gear 144 to rotate through the first gear 143. The rotation of the second gear 144 drives the rotating rod 146 to rotate through the third gear 149, and the first spring 148 is deformed. The rotation of the rotating rod 146 drives the baffle 147 to rotate and no longer block the third descending plate 113. The third descending plate 113 and the second descending plate 112 can then move downward automatically for sampling. Subsequently, the operation of the servo motor 142 is stopped. After sampling is completed, the third descending plate 113 and the second descending plate 112 are pushed upward to reset. The servo motor 142 is started to reverse, and the baffle 147 is driven to rotate in the reverse direction through the rotating rod 146 to block the third descending plate 113, and the first spring 148 is reset.

[0038] Embodiment 3

[0039] On the basis of Embodiment 2, as Figure 7 、 Figure 10 and Figure 11 shown, it further includes a switch mechanism 13. The switch mechanism 13 includes an elastic plate 131, a handle 132 and a force-receiving block 133. The elastic plate 131 is slidably arranged on the front side of the sampling box 121. The elastic plate 131 is located in the water inlet 123. A force-receiving block 133 is arranged on the front right side of the elastic plate 131, and a handle 132 is arranged on the front side of the force-receiving block 133.

[0040] It further includes a metering mechanism 15. The metering mechanism 15 includes a guide rail 151, a second spring 152, a top block 153, a top rod 154, a first telescopic rod 155, a second telescopic rod 156, a third telescopic rod 157 and a pushing block 158. The guide rail 151 is arranged on the front side of the sampling box 121. The top block 153 is slidably arranged in the guide rail 151. The top block 153 is connected to the handle 132. Two second springs 152 are connected between the left side of the top block 153 and the inner wall of the guide rail 151. The first telescopic rod 155, the second telescopic rod 156 and the third telescopic rod 157 are sequentially installed on the front side of the top block 153 from top to bottom. The top rod 154 is arranged at the top of the first telescopic rod 155. A pushing block 158 is arranged inside the second gear 144. The pushing block 158 cooperates with the top rod 154.

[0041] After the baffle 147 rotates and no longer blocks the third descending plate 113, the third descending plate 113 and the second descending plate 112 move downward, driving the second telescopic rod 156 and the third telescopic rod 157 to move downward. The staff can adjust the width of the water inlet 123 according to requirements. The second gear 144 continues to rotate and drives the ejector rod 154 to rotate through the push block 158. The rotation of the ejector rod 154 drives the first telescopic rod 155, the second telescopic rod 156 and the third telescopic rod 157 to move leftward, so as to drive the handle 132 to move leftward through the top block 153. The leftward movement of the handle 132 drives the elastic plate 131 to move leftward through the force-receiving block 133. When the elastic plate 131 moves to an appropriate position, the operation of the servo motor 142 is stopped, so that the subsequent components stop operating. The second spring 152 and the elastic plate 131 are both compressed. After sampling, the third descending plate 113 and the second descending plate 112 move upward, driving the second telescopic rod 156 and the third telescopic rod 157 to move upward and reset. The reverse rotation of the servo motor 142 drives the push block 158 through the second gear 144 to no longer apply force to the ejector rod 154. The second spring 152 drives the top block 153 to move rightward and reset, and the elastic plate 131 resets to block the water inlet 123.

[0042] Embodiment 4

[0043] On the basis of Embodiment 3, as Figures 12 to 14 shown, it further includes a protection mechanism 16. The protection mechanism 16 includes a support seat 161, a support rod 162, a third spring 163 and a push plate 164. A plurality of support seats 161 are provided at the bottom of the floating plate 1. The support rod 162 is slidably provided at the bottom of the support seat 161. The push plate 164 is provided at the bottom of each support rod 162. A third spring 163 is connected between the support rod 162 and the bottom of the support seat 161.

[0044] It further includes a storage mechanism 17. The storage mechanism 17 includes a storage plate 171, a storage rack 172, a continuous winding rack 173, a sliding sleeve 174, a sliding rod 175, a pressing block 176, a pull rope 177 and a special-shaped rod 178. Three storage plates 171 are provided at the top of the floating plate 1. The storage rack 172 is connected between the tops of the storage plates 171. The continuous winding rack 173 is connected between the top inner walls of the storage rack 172. The sliding sleeve 174 is provided at the top left of the continuous winding rack 173. The sliding rod 175 is slidably provided on the sliding sleeve 174. The special-shaped rod 178 is provided at the left part of the sliding rod 175. The special-shaped rod 178 cooperates with the top block 153. The pressing block 176 is provided at the top of the continuous winding rack 173. The pressing block 176 is located on the left side of the sliding sleeve 174. The pull rope 177 is provided at the top of the continuous winding rack 173. The pull rope 177 is located on the right side of the pressing block 176.

[0045] When the water level is relatively shallow, the downward movement of the device drives the push plate 164 to contact the water surface first, which can reduce the impact force between the water surface and the device. At the same time, it can prevent waterweeds from entangling the device, and the third spring 163 can play a buffering role; the staff can throw the device into the water by pinching one end of the pulling rope 177. After the device stops, the coiling frame 173 automatically winds up the pulling rope 177 under the action of gravity. At this time, the top block 153 moves leftward to contact the special-shaped rod 178, and the leftward movement of the special-shaped rod 178 drives the sliding rod 175 to move leftward to cooperate with the extrusion block 176 to clamp the pulling rope 177. After sampling, the staff can recycle the device through the pulling rope 177.
