Description

Technical Field

[0001] This application relates to the technical field of aquaculture equipment, and in particular to an automatic eel weighing and screening device. Background Art

[0002] During the industrialized eel farming process, due to different growth rates, it is necessary to grade and screen the eels. The eels are sent from the eel farming pond to the eel separator. After the eels are screened, eels of different sizes enter different temporary holding ponds to avoid the situation where big fish prey on small fish and compete for food with each other. At the same time, it can also enable eels of different sizes to absorb the nutrients they should have at this growth stage, improving the quality of eel farming.

[0003] There is an existing eel separator in the prior art. The separator includes a sieve for screening eels, a rack for installing the sieve, and a collection pond for collecting eels. A receiving chamber for receiving eels is provided below the sieve, and a fish discharge pipe for transporting eels to the collection pond is provided at the bottom of the receiving chamber. During screening, eels of similar specifications are screened through sieves corresponding to different specifications. The eels enter the receiving chamber through the gaps of the sieve, and the eels enter different collection ponds along the fish discharge pipe for temporary holding, so as to obtain eels of different specifications. After screening, the eels are manually fished out from the collection pond and sent to the corresponding-sized breeding ponds for cultivation.

[0004] In view of the above-related technologies, after the eels are screened, it is necessary to manually fish out the eels from the collection pond and weigh the fished eel group to estimate the number of eels to be sent to the breeding pond. This method has low efficiency. Summary of the Invention

[0005] In order to improve the problem of low efficiency in the prior art during the transfer process of eels, this application provides an automatic eel weighing and screening device.

[0006] The following technical scheme is adopted:

[0007] An automatic eel weighing and screening device includes a frame body, a lifting box, a placement pool, and a screening pool. The lifting box is slidably connected to the frame body along the direction of gravity. One side of the lifting box is connected with a towing cable. A towing member for winding or releasing the towing cable is provided at one end of the frame body away from the ground. A weighing meter is provided between the lifting box and the towing cable. The placement pool is arranged on the frame body. The lifting box is provided with a fish discharge pipe that can communicate with the placement pool. The fish discharge pipe is provided with an opening and closing member for closing or opening the pipe orifice. The placement pool is connected to the screening pool through a fish conveying pipe. The screening pool is provided with a number of fish screening pipes connected to the corresponding breeding ponds.

[0008] By adopting the above technical solution, after the eels are sorted, the eels are fed into the lifting box in batches. The traction member lifts the lifting box, and the weight of the eels in the lifting box is measured by the weighing meter. Then, the traction cable guides the lifting box to the position of the placement pool. At this time, the fish discharge pipe corresponds to the placement pool, and the opening and closing member is opened, so that the eels swim into the placement pool on the rack for temporary storage. Then, the eels swim into the sorting pool through the fish conveying pipe and are connected to the corresponding breeding pools through the fish screening pipe, so that the eels enter the corresponding breeding pools, thereby providing an automated eel transfer solution. At the same time, the weight of the eels entering the breeding pool can also be measured to estimate the number of eels in the breeding pool.

[0009] Optionally, the opening and closing member includes a gate plate, a cable, and a starting block. The gate plate is slidably connected to the inner wall of the lifting box. When the gate plate hangs naturally, it covers the nozzle of the fish discharge pipe. One side of the gate plate is connected to the cable, and the cable extends upward and passes through the side wall of the lifting box to be connected to the starting block. The rack is provided with an abutting block on the moving path of the lifting box for abutting against the starting block to pull the cable so that the fish discharge pipe is communicated with the placement pool.

[0010] By adopting the above technical solution, the lifting box is pulled by the traction cable and lifted vertically along the rack. When the lifting box is lifted to the position corresponding to the placement pool, the starting block arranged outside the lifting box abuts against the abutting block. The lifting box continues to be lifted, and the starting block is restricted by the abutting block. The starting block moves downward relative to the lifting box, thereby driving the gate plate away from the fish discharge pipe through the cable, so that the fish discharge pipe is communicated with the internal space of the lifting box.

[0011] Optionally, a transition hose is arranged at one end of the fish discharge pipe away from the lifting box. The transition hose extends into the extension surface of the side of the placement pool close to the lifting box. The transition hose has the elasticity to restore its initial state.

[0012] By adopting the above technical solution, the transition hose moves with the lifting box. When passing through structures such as the placement pool, the transition hose deforms to pass through the obstructive structure. When reaching the upper part of the placement pool, the transition hose restores its initial state, that is, it extends into the placement pool to prevent the eels from falling out of the placement pool.

[0013] Optionally, it further includes a water collecting tank, which includes a housing, a connecting pipe, and several support cylinders. The several support cylinders are arranged parallel to the ground in sequence along the gravity direction. The several support cylinders are connected by an overflow pipe. One end of the overflow pipe is connected to the side of the support cylinder away from the ground, and the other end is connected to the side of the adjacent support cylinder away from the ground. One end of the connecting pipe communicates with the support cylinder farthest from the ground, and the other end vertically penetrates the side wall of the water collecting tank. A drainage groove is formed on the inner wall of the lifting tank close to the ground, and a water permeable hole vertically penetrating the outer wall of the lifting tank is formed in the drainage groove. The position of the water permeable hole corresponds to the position of the connecting pipe, and a control member for closing or opening the water permeable hole is arranged on the water permeable hole.

[0014] By adopting the above technical solution, the lifting tank is generally arranged in a ground groove. In the traditional method, several drainage holes are opened on the side wall of the lifting tank to drain water. The water collecting tank is used to collect the water that enters the lifting tank along with the eel group, so as to measure the weight of the eels more accurately, and at the same time prevent the water from flowing into the ground groove. After the water evaporates, the impurities mixed in the water adhere to the inner wall of the ground groove, generating a foul smell; the water flows into the support cylinder through the connecting pipe, and the impurities precipitate. After the water in the support cylinder overflows, the water enters the next support cylinder through the overflow pipe, so as to collect the impurities and avoid the impurities from adhering to the inner wall of the ground groove.

[0015] Optionally, the control member includes a hole sealing piece and a support block. The support block is vertically provided with several support bars arranged in a circumferential array. The hole sealing piece is slidably connected vertically between the several support bars. The hole sealing piece is vertically provided with several sealing strips staggered with the several support bars. A slot for inserting the several sealing strips is formed on the support block. A first elastic member for making the hole sealing piece always abut against the inner wall of the drainage groove to close the water permeable hole is arranged between the hole sealing piece and the support block. A push rod for pushing the hole sealing piece to move is arranged in the connecting pipe.

[0016] By adopting the above technical solution, when the lifting tank abuts against the water collecting tank from top to bottom, the push rod penetrates through the water permeable hole to push the hole sealing piece away from the water permeable hole. At this time, the inside of the drainage groove is communicated with the water permeable hole, and the water flows into the connecting pipe through the water permeable hole, so as to drain the water in the lifting tank. When the lifting tank leaves the water collecting tank, the first elastic member pushes the hole sealing piece to close the water permeable hole to prevent the remaining water from dripping and affecting the environment.

[0017] Optionally, a sewage intercepting cylinder is arranged in the support cylinder. An inlet hole corresponding to the overflow pipe or the connecting pipe is formed in the sewage intercepting cylinder. The water collecting tank is provided with several extraction holes respectively corresponding to the positions of one ends of the several support cylinders. One end of the support cylinder is penetrated to allow the sewage intercepting cylinder to slide out of the support cylinder.

[0018] By adopting the above technical solution, water and impurities are stored in the sewage interception cylinder. The sewage interception cylinder is taken out to clean the impurities, which is more convenient to operate than deeply cleaning the support cylinder fixed in the water collection tank.

[0019] Optionally, the sewage intercepting barrel is slidably connected with a docking tube at several of the water inlet holes, and the docking tube can be slid to be connected with the overflow pipe or the connecting pipe, a first magnetic ring is provided at one end of the docking tube, and the overflow pipe and the connecting pipe are both provided with a second magnetic ring that cooperates with the first magnetic ring, and a guide sheet is provided in the support tube for guiding the docking tube to be retracted into the extended surface of the outer surface of the sewage intercepting barrel after the sewage intercepting barrel rotates.

[0020] By adopting the above technical solution, when it is necessary to take out the sewage interception cylinder, first rotate the sewage interception cylinder so that the docking tube abuts against the guide piece and moves along the guide piece to be received into the extended surface of the outer wall of the sewage interception cylinder, so that the sewage interception cylinder can be taken out. When installing the sewage interception cylinder, the operation is reversed. When the docking tube moves to the position corresponding to the overflow pipe or the connecting pipe, the first magnetic ring cooperates with the second magnetic ring to attract each other, so that the docking tube and the corresponding pipe are connected.

[0021] Optionally, the inner wall of the sewage interception barrel is rotatably connected with a baffle along its length, and the baffle can be rotated to close a plurality of water inlet holes, a connecting rod is provided at one end of the baffle along the radius of the sewage interception barrel, and a control rod is provided at one end of the connecting rod away from the baffle, which passes through the sewage interception barrel along the axis of the sewage interception barrel to the outside.

[0022] By adopting the above technical solution, when it is necessary to take out the dirt intercepting cylinder, the blocking bar is rotated to block the water inlet hole to prevent water from leaking through the water inlet hole when the dirt intercepting cylinder is taken out.

[0023] Optionally, the sewage interception cylinder comprises a control block, a rotation groove is formed on an outer wall of the control block, a rotation handle is rotatably connected in the rotation groove, and the control rod is connected to the rotation handle.

[0024] By adopting the above technical solution, the control block is driven to rotate by rotating the rotating handle outside the sewage interception cylinder, so that the blocking bar blocks the water inlet hole.

[0025] Optionally, the sewage interception barrel is provided with two arc-shaped limit grooves on the side wall where the rotating groove is located, and the rotating handle is provided with a limit block that can slide in the limit groove, one end of the limit groove extends along the length direction of the sewage interception barrel to form a yield groove, and the control block is provided with a second elastic member that enables the rotating handle to always have a tendency to move away from the control block, the rotating handle is provided with a rotating rod, the rotating rod is inserted into the control rod, one end of the rotating rod is provided with a straight block, the control rod is provided with a straight groove for the straight block to be inserted, and the control rod is also provided with a groove for the straight block to rotate, and the groove is connected to the straight groove.

[0026] By adopting the above technical solution, when it is necessary to take out the sewage intercepting barrel, the rotating handle is rotated so that the blocking piece blocks the water inlet hole. At this time, the limit block slides in the limit groove to the give way groove, and the second elastic member pushes the rotating handle to move so that the limit block enters the give way groove. The rotating handle continues to be rotated. At this time, the limit block abuts against the wall of the give way groove, so that the sewage intercepting barrel rotates as a whole, and the docking tube abuts against the guide piece. The rotation continues to be rotated to recycle the docking tube, and the rotating handle is pulled outward along the length direction of the sewage intercepting barrel to pull out the sewage intercepting barrel.

[0027] In summary, the present application includes at least one of the following beneficial effects:

[0041] Refer to Figure 1 and Figure 2, an embodiment of the present application discloses an automatic eel weighing and screening device, which includes a frame body 3, a lifting box 5, a placement pool 4 and a screening pool 2. The frame body 3 is vertically erected on the ground surface. A ground slot 1 is dug downward on one side of the frame body 3 for ground grooving. The lifting box 5 is arranged in the ground slot 1 to facilitate the input of eels into the lifting box 5. A ladder 11 for workers to climb is also arranged on one side of the ground slot 1. The frame body 3 is provided with a slide rail 31 along the length direction. The lifting box 5 is slidably connected to the slide rail 31 along the direction of gravity. One side of the lifting box 5 is connected with a towing cable 51. A towing member 32 for winding or releasing the towing cable 51 is arranged at one end of the frame body 3 away from the ground. The towing member 32 is a winding roller driven by a motor. A weighing meter 52 is arranged between the lifting box 5 and the towing cable 51. One end of the weighing meter 52 is hooked on the lifting box 5, and the other end is connected to the towing cable 51. The placement pool 4 is arranged at a relatively far distance from the ground on the frame body 3. The lifting box 5 is provided with a fish discharge pipe 53 that can communicate with the placement pool 4. The fish discharge pipe 53 is provided with an opening and closing member for closing or opening the pipe orifice. The screening pool 2 is arranged on the ground surface. The placement pool 4 and the screening pool 2 are connected by a fish conveying pipe 41. The fish conveying pipe 41 is inclined from top to bottom. The screening pool 2 is provided with a number of fish screening pipes 21 connected to the corresponding breeding ponds. A blocking member (not marked in the figure) is arranged in the fish screening pipes 21.

[0042] Refer to Figure 2 , the opening and closing member includes a gate piece 54, a cable 55 and a starting block 56. The gate piece 54 is slidably connected to the inner wall of the lifting box 5. A limiting rail for restricting the gate piece 54 to move only vertically is arranged vertically on the inner wall of the lifting box 5 at the fish discharge pipe 53. When the gate piece 54 hangs naturally, it covers the pipe orifice of the fish discharge pipe 53. One side of the gate piece 54 is connected with the cable 55. The cable 55 extends upward and passes through the side wall of the lifting box 5 to be connected with the starting block 56. The starting block 56 hangs naturally outside the lifting box 5. The frame body 3 is provided with an abutting block 33 on the moving path of the lifting box 5 for abutting against the starting block 56 to pull the cable 55 so that the fish discharge pipe 53 communicates with the placement pool 4. The lifting box 5 is pulled by the towing cable 51 and lifted vertically along the frame body 3. When the lifting box 5 is lifted to the corresponding position of the placement pool 4, the starting block 56 arranged outside the lifting box 5 abuts against the abutting block 33. The lifting box 5 continues to be lifted. The starting block 56 is restricted by the abutting block 33. The starting block 56 moves downward relative to the lifting box 5, so as to drive the gate piece 54 away from the fish discharge pipe 53 through the cable 55, so that the fish discharge pipe 53 communicates with the internal space of the lifting box 5.

[0043] Refer to Figure 2, one end of the fish discharging pipe 53 away from the lifting tank 5 is provided with a transition hose 531. The transition hose 531 extends into the side of the placing tank 4 close to the lifting tank 5. The transition hose 531 has the elasticity to restore its initial state. The transition hose 531 moves with the lifting tank 5. When passing through structures such as the placing tank 4, the transition hose 531 deforms to pass through the obstructive structure. Above the placing tank 4, the transition hose 531 restores its initial state, that is, it extends into the placing tank 4 to prevent the eels from falling out of the placing tank 4.

[0044] Refer to Figures 3 to 6 , the automatic eel weighing and screening device further includes a water collecting tank 7. The water collecting tank 7 includes a housing 71, a connecting pipe 721 and a plurality of support cylinders 72. The housing 71 is a hollow rectangle. A plurality of support cylinders 72 are arranged in the housing 71 parallel to the ground in sequence along the gravity direction. A plurality of support cylinders 72 are connected by an overflow pipe 722. One end of the overflow pipe 722 is connected to the side of the support cylinder 72 away from the ground, and the other end is connected to the side of the adjacent support cylinder 72 away from the ground. One end of the connecting pipe 721 communicates with the support cylinder 72 farthest from the ground, and the other end vertically penetrates the upper surface of the water collecting tank 7. A drain groove 57 is opened on the inner wall of the lifting tank 5 close to the ground. The drain groove 57 is opened along the length of the bottom side of the side close to the frame 3. The inner wall of the bottom of the lifting tank 5 is inclined towards the drain groove 57. The drain groove 57 is covered with a filter strip 571. A water permeable hole 572 vertically penetrating the outer wall of the lifting tank 5 is opened in the drain groove 57. The position of the water permeable hole 572 corresponds to the position of the connecting pipe 721. A control member 6 for closing or opening the water permeable hole 572 is provided on the water permeable hole 572. In the traditional method, a plurality of drain holes are opened on the side wall of the lifting tank 5 to discharge the water body. The water body entering the lifting tank 5 along with the eel group is collected by the water collecting tank 7 to measure the weight of the eels more accurately. At the same time, to prevent the water body from flowing into the ground groove 1. After the water body evaporates, the impurities mixed in the water body adhere to the inner wall of the ground groove 1, generating a foul smell. The water body flows into the support cylinder 72 through the connecting pipe 721, and the impurities precipitate. After the water body in the support cylinder 72 overflows, the water body enters the next support cylinder 72 through the overflow pipe 722 to collect the impurities, thus preventing the impurities from adhering to the inner wall of the ground groove 1.

[0045] Refer to Figure 4 and Figure 5, the control member 6 includes a hole-sealing piece 61 and a support block 62. The support block 62 is vertically provided with a plurality of support bars 621 arranged in a circumferential array. The hole-sealing piece 61 is slidably connected in the vertical direction between the plurality of support bars 621. The hole-sealing piece 61 is vertically provided with a plurality of sealing strips 611 staggered with the plurality of support bars 621. The support block 62 is provided with slots 622 for inserting the plurality of sealing strips 611. A first elastic member 63 for making the hole-sealing piece 61 always abut against the inner wall of the drainage groove 57 to close the water-permeable holes 572 is arranged between the hole-sealing piece 61 and the support block 62. The first elastic member 63 is a spring. A push rod 64 for pushing the hole-sealing piece 61 to move is arranged in the communication pipe 721. Cross-shaped blocks 641 are arranged at both ends of the push rod. One cross-shaped block 641 at one end is connected to the inner wall of the communication pipe 721, and the cross-shaped block 641 at the other end is used to push the hole-sealing piece 61. When the lifting box 5 abuts against the water collecting box 7 from top to bottom, the push rod 64 penetrates through the water-permeable holes 572 to push the hole-sealing piece 61 away from the water-permeable holes 572. At this time, the inside of the drainage groove 57 is communicated with the water-permeable holes 572, and the water body flows into the communication pipe 721 through the water-permeable holes 572, so as to drain the lifting box 5. When the lifting box 5 leaves the water collecting box 7, the first elastic member 63 pushes the hole-sealing piece 61 to close the water-permeable holes 572 to prevent the remaining water body from dripping and affecting the environment.

[0046] Referring to Figure 6 and Figure 7 , a sewage intercepting cylinder 8 is arranged in the support cylinder 72. An inlet hole 81 corresponding to the overflow pipe 722 or the communication pipe 721 is opened in the sewage intercepting cylinder 8. A plurality of extraction holes 711 corresponding to one end positions of the plurality of support cylinders 72 are respectively opened in the water collecting box 7. One end of the support cylinder 72 is penetrated to allow the sewage intercepting cylinder 8 to slide out of the support cylinder 72. The water body and impurities are stored in the sewage intercepting cylinder 8. By taking out the sewage intercepting cylinder 8 to clean the impurities, the operation is more convenient than deeply cleaning the support cylinder 72 fixed in the water collecting box 7.

[0047] Referring to Figures 6 to 9, at several water inlet holes 81 of the sewage intercepting cylinder 8, there are slidingly connected with connecting pipes 82. The outer diameter of the connecting pipe 82 is equal to the inner diameter of the water inlet hole 81. The connecting pipe 82 is provided with a convex block 821. On the inner wall where the water inlet hole 81 is located, there is a connecting groove 811 vertically arranged for the convex block 821 to slide. The connecting pipe 82 can slide to be connected with the overflow pipe 722 or the communicating pipe 721. One end of the connecting pipe 82 is provided with a first magnetic ring 822. Both the overflow pipe 722 and the communicating pipe 721 are provided with a second magnetic ring 823 that cooperates with the first magnetic ring 822. Inside the support cylinder 72, there is a guiding piece 73 that guides the connecting pipe 82 to be received into the extension surface of the outer surface of the sewage intercepting cylinder 8 after the sewage intercepting cylinder 8 rotates. The guiding piece 73 is an arc-shaped piece, and together with the support cylinder 72, it forms a cross-section in the shape of "6". A filter piece 824 is arranged in the connecting pipe 82 through which the water supply flows to intercept impurities in the sewage intercepting cylinder 8. When the sewage intercepting cylinder 8 needs to be taken out, first rotate the sewage intercepting cylinder 8 so that the connecting pipe 82 abuts against the guiding piece 73 and moves along the guiding piece 73 to be received into the extension surface of the outer wall of the sewage intercepting cylinder 8, so that the sewage intercepting cylinder 8 can be taken out. When installing the sewage intercepting cylinder 8, operate in the reverse direction. When the connecting pipe 82 moves to the corresponding position of the overflow pipe 722 or the communicating pipe 721, the first magnetic ring 822 and the second magnetic ring 823 attract each other, so that the corresponding pipes of the connecting pipe 82 are connected.

[0048] Refer to Figures 6 to 9 , on the inner wall of the sewage intercepting cylinder 8 along the length, there is a rotating connection with a blocking strip 83. The cross-section of the blocking strip 83 is arc-shaped. The blocking strip 83 can rotate to block several water inlet holes 81. One end of the blocking strip 83 is provided with a connecting rod 831 along the radius of the sewage intercepting cylinder 8. The end of the connecting rod 831 away from the blocking strip 83 is provided with a control rod 84 that penetrates through the sewage intercepting cylinder 8 along the axis to the outside. The control rod 84 is cylindrical. A connecting block 832 is arranged on the blocking strip 83, and an arc-shaped adaptation groove 833 for the connecting block 832 to slide is opened on the inner wall of the sewage intercepting cylinder 8. When the sewage intercepting cylinder 8 needs to be taken out, rotate the blocking strip 83 to block the water inlet holes 81 to prevent water from leaking through the water inlet holes 81 when the sewage intercepting cylinder 8 is taken out.

[0049] Refer to Figures 6 to 9 , the sewage intercepting cylinder 8 includes a control block 85. The control block 85 is a cylindrical block that seals one end of the sewage intercepting cylinder 8. A circular rotating groove 851 is opened on the outer wall of the control block 85. A rotating handle 86 is rotatably connected in the rotating groove 851. The rotating handle 86 is arc-shaped with the same curvature at both ends as the rotating groove 851, and the middle of the rotating handle 86 is penetrated to facilitate manual gripping. The control rod 84 is connected to the rotating handle 86. By rotating the rotating handle 86 outside the sewage intercepting cylinder 8, the control block 85 is driven to rotate, so that the blocking strip 83 blocks the water inlet holes 81.

[0050] Refer to Figures 6 to 9The sewage intercepting barrel 8 is provided with two arc-shaped limit grooves 852 on the side wall where the rotating groove 851 is located. The shape of the limit grooves 852 corresponds to the rotation path of the blocking bar 83. The rotating handle 86 is provided with a limit block 861 that can slide in the limit groove 852. One end of the limit groove 852 extends along the length direction of the sewage intercepting barrel 8 to form a clearance groove 853. The cross-sectional shape of the clearance groove 853 corresponds to the shape of the limit block 861. The control block 85 is provided with a second elastic member 87 that makes the rotating handle 86 always have a tendency to move away from the control block 85. The second elastic member 87 is a spring. The rotating handle 86 is provided with a rotating rod 862, which is inserted into the control rod 84, and a block 863 is provided at one end of the rotating rod 862. The control rod 84 is provided with a slot 841 for inserting the block 863. The control rod 84 is also provided with a groove 842 for rotating the block 863. The groove 842 is a circular groove, and the groove 842 is connected with the slot 841. The rotating handle 86 drives the stopper 83 to close the water inlet hole 81. During this process, the block 863 is inserted into the slot 841, so that the rotating rod 862 can drive the control rod 84 to rotate, and the limit block 861 slides from the limit slot 852 to the clearance slot 853. The second elastic member 87 pushes the rotating handle 86, so that the limit block 861 is stuck in the clearance slot 853. At this time, the block 863 enters the slot 842, and the rotating handle 86 is continuously rotated to drive the sewage interception cylinder 8 to rotate as a whole.

[0051] Reference Figure 6 The outer wall of one end of the sewage interception tube 8 provided with a control block 85 is provided with a thread connected to the support tube 72. The end of the sewage interception tube 8 away from the control block 85 is through-connected and provided with an end cover 88 for closing the sewage interception tube 8. The end cover 88 is threadedly connected to the sewage interception tube 8, and a handle is provided on the end cover 88 for convenient manual rotation.

[0052] The implementation principle of the automatic weighing and screening device for eels in the embodiment of the present application is as follows:

[0053] After the eels are screened, they are sent to the lifting box 5 in batches. The traction member 32 pulls up the lifting box 5, and the weight of the eels in the lifting box 5 is measured by the weighing meter 52, and the weight of the eels entering the breeding pool is measured to estimate the number of eels in the breeding pool. The rear traction rope 51 guides the lifting box 5 to the placement pool 4. At this time, the fish discharge pipe 53 corresponds to the placement pool 4, and the opening and closing member is opened, so that the eels swim into the placement pool 4 on the frame 3 for temporary storage, and then the eels swim into the screening pool 2 through the fish delivery pipe 41, and are connected to the corresponding breeding pool through the screening fish pipe 21.

[0054] When the eels are sent into the lifting box 5, water flows into the sewage interception barrel 8 through the connecting pipe 721, and impurities are precipitated. After the water in the sewage interception barrel 8 is overflowing, the water flows into the next sewage interception barrel 8 through the overflow pipe 722, thereby collecting impurities and preventing the impurities from adhering to the inner wall of the ground groove 1.

[0055] When it is necessary to take out the sewage intercepting barrel 88, the rotating handle 86 is rotated so that the blocking piece blocks the water inlet hole 81. At this time, the limiting block 861 slides in the limiting groove 852 to the giving groove 853. The second elastic member 87 pushes the rotating handle 86 to move so that the limiting block 861 enters the giving groove 853. The rotating handle 86 is continuously rotated. At this time, the limiting block 861 abuts against the wall of the giving groove 853, so that the sewage intercepting barrel 8 rotates as a whole, so that the docking tube 82 abuts against the guide piece 73. The rotation is continued to be recovered to recycle the docking tube 82. The rotating handle 86 is pulled outward along the length direction of the sewage intercepting barrel 8 to pull out the sewage intercepting barrel 8, and the impurities in the sewage intercepting barrel 8 are dumped by opening the end cover 88.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
