[0002] Urban sewage treatment refers to the purification of urban domestic polluted water through physical, chemical and biological methods to remove pollutants. Among them, the treatment of polluted water in urban rivers is particularly critical. During the initial treatment, some technical means are usually used to remove floating objects or other garbage in the river to keep the water clean. The common treatment method is to set up an interception device. However, in the actual process, the existing interception devices often lack a guiding mechanism to guide and centrally collect floating objects in the sewage, which causes the floating objects in the sewage to accumulate on the interception device, which in turn causes the floating objects in the sewage to accumulate and clog, requiring frequent cleaning and maintenance. In addition, the large-scale setting of the interception device will also affect the normal activities of aquatic organisms and affect the river ecology. Summary of the invention

DETAILED DESCRIPTION

[0014] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0015] See also Figure 1-5 As shown in the figure, a municipal sewage treatment device provided by the present embodiment includes a support frame 101, one side of the support frame 101, which faces the water flow, is fixedly connected with a guide plate 1, the guide plate 1 is arranged in a V shape, a collecting net bag 20 is detachably installed in the middle of the support frame 101, the opening of the guide plate 1 gradually narrows from the outside to the inside until it is connected with the opening of the collecting net bag 20, a connecting rod 2 is fixedly connected to the top of the support frame 101, and an end of the connecting rod 2 away from the support frame 101 is rotatably connected with an impeller 3, a part of the main body of the impeller 3 is immersed in the river, and when working, the impeller 3 starts to rotate under the influence of the water flow, and effectively disperses the floating objects attached and accumulated around, and directly pushes these floating objects into the collecting net bag 20;

[0016] Specifically, the guide plate 1 is provided with a groove in the vertical direction, and a reciprocating screw 4 is fixedly connected to the axial position of the outer wall of the impeller 3, which can drive the reciprocating screw 4 to rotate synchronously when the impeller 3 rotates; a sliding block 5 is sleeved on the outer wall of the reciprocating screw 4, and a sliding rod 6 is slidably connected to the bottom of the sliding block 5, and a sliding groove is provided on the sliding rod, and the sliding block 5 can move back and forth in the sliding groove of the sliding rod; a hinge 7 is slidably connected to the bottom of the sliding rod 6, and one end of the bottom of the hinge 7 is slidably connected to the opening of the groove 22 of the guide plate 1, and the hinge 7 can move back and forth in the groove 22 of the guide plate 1; a push plate 8 is hinged to the other end of the bottom of the hinge 7, and the push plate 8 is arranged in contact with the guide plate 1, and a limiting plate 9 is fixedly connected to the side of the bottom of the hinge 7 away from the impeller 3. Through the setting of the limiting plate 9, the push plate 8 can be limited from flipping in the direction away from the impeller 3.

[0017] It can be understood that, firstly, the end of the water surface floating object treatment device provided with the guide plate 1 is installed facing the flow direction of the river water flow, so that the floating objects on the water surface can be intercepted by the guide plate 1 when following the water flow, and at the same time, when the water flows through the impeller 3, the impeller 3 starts to rotate under the influence of the water flow, thereby effectively dispersing the floating objects attached and accumulated around, and directly pushing these floating objects into the collection net bag 20; in addition, those floating objects that are not directly pushed in will also lose their adhesion after being dispersed, and then be brought into the collection net bag 20 by the water flow, so as to ensure the efficient cleaning and collection of the floating objects;

[0018] At the same time, when the impeller drives the reciprocating screw 4 to rotate, the sliding block 5 can drive the push plate 8 to move in the direction of the collecting net bag 20 in close contact with the guide plate 1, and under the limit of the limit plate 9, the push plate 8 will not flip over due to the resistance of the water, so that the push plate 8 can always maintain a vertical state, pushing more floating objects to gather toward the impeller 3 with the maximum area, and then driven by the impeller 3, the floating objects are pushed into the collecting net bag 20; in this process, the present application uses the fluidity of water to provide power, so that the impeller 3 and the push plate 8 can guide the floating objects within a larger range, so that they are concentrated in a smaller collecting net bag 20, avoiding the accumulation and blockage of floating objects in the sewage, and requiring frequent cleaning and maintenance, while there is no need to set up interception nets over a large area, so as to avoid affecting the normal activities of aquatic organisms and ensure the ecological stability of the river.

[0019] Furthermore, a floating airbag 13 is fixedly installed between the support frame 101 and the guide plate 1 .

[0020] It should be noted that, although the push plate 8 can push and gather the floating objects attached to and accumulated on the guide plate 1 around the impeller 3, when the sliding block 5 drives the push plate 8 to move in the reverse direction, some of the floating objects will be pushed away from the collection net bag 20 along with the push plate 8. Therefore, further improvements can be made, as detailed below:

[0021] Further, the guide plate 10 is horizontally arranged on the upper part of the guide plate 1, and the guide plate 10 passes through the guide plate 1 to the groove 22. A triangular protrusion is fixedly connected to one side of the guide plate 10 located outside the guide plate 1, and a first spring 11 is fixedly installed on one side of the guide plate 10 located in the groove 22 of the guide plate 1, so that the guide plate 10 can move on the guide plate 1;

[0022] Preferably, the triangular protrusions on the guide rod are arranged evenly at intervals, the corner of the triangular protrusion close to the collecting net bag 20 is set at 90 degrees, and the corner close to the push plate 8 is set at an acute angle. When the guide plate 1 is in water, the triangular protrusion is located above the horizontal plane.

[0023] It can be understood that when the sliding block 5 drives the push plate 8 to move in the opposite direction, the triangular protrusion further causes the push plate 8 to rotate and leave the water surface, and to be in a nearly horizontal state, so that the push plate 8 will not allow floating objects to be pushed to a position away from the collecting net bag 20 during the resetting process; when the hinge 7 drives the push plate 8 to reach the end of the reciprocating screw 4 away from the impeller 3, the triangular protrusion on the guide plate 10 cannot limit the push plate 8 due to distance reasons, so that the push plate 8 can naturally rotate and reset to a vertical state under the action of gravity.

[0024] When the sliding block 5 drives the push plate 8 to move toward the collecting net bag 20, the angle of the triangular protrusion is small, so that the guide plate 10 is subjected to the inward squeezing force of the push plate 8, so that the first spring 11 contracts and drives the guide plate 10 and the stop block 12 to contract into the guide plate 1, so that the push plate 8 can smoothly fit the guide plate 1 and maintain a vertical state to push the floating objects to gather toward the impeller 3.

[0025] Furthermore, a stopper 12 is fixedly connected to the guide plate 1 near the opening of the collecting net bag 20. When the guide plate 1 is in water, the stopper 12 is located below the horizontal plane. Through the setting of the stopper 12, since the stopper 12 is below the triangular protrusion, the torque of the stopper 12 is greater and it is easier to push the push plate 8 to rotate. When the sliding block 5 drives the push plate 8 to move in the opposite direction, the push plate 8 can be first blocked by the stopper 12 and rotated to a certain angle in the direction of the collecting net bag 20 to prevent the push plate 8 from being stuck due to the inability of the triangular protrusion to rotate.

[0026] Furthermore, the support frame 101 is provided with a mounting groove 23, a clamping piece 17 is installed in the mounting groove 23, a second spring 18 is fixed on the top of the clamping piece 17, a mounting frame 19 is clamped in the mounting groove 23 through the clamping piece 17, and the collecting net bag 20 is fixed on the mounting frame 19.

[0027] Reference Figure 4-5As shown, a mounting groove 23 for mounting a collecting net bag 20 is provided on one end of the supporting frame 101 away from the guide plate 10, a clamping piece 17 is installed at the middle position inside the mounting groove 23, a second spring 18 is fixedly installed on the top of the clamping piece 17, the second spring 18 is fixedly installed inside the mounting groove 23, a mounting frame 19 is clamped inside the mounting groove 23 through the clamping piece 17, and the collecting net bag 20 is fixedly installed on the outer wall of the mounting frame 19.

[0028] Furthermore, a push-pull rod 14 is inserted into the installation groove 23, a first push block 15 is fixedly connected to the middle of the push-pull rod 14, the first push block 15 is affixed to the right end surface of the installation frame 19, and a second push block 16 is fixedly connected to the end of the push-pull rod 14, the second push block 16 is affixed to the left protrusion of the clamping piece 17.

[0029] Specifically, a push-pull rod 14 is inserted into the inside of the mounting groove 23, and the other end of the push-pull rod 14 protrudes out of the mounting groove 23. A first push block 15 is fixedly connected to the middle of the outer wall of the push-pull rod 14, and the first push block 15 is attached to the right end surface of the mounting frame 19, and the height of the first push block 15 is less than the gap height between the right protrusion on the clip 17 and the bottom surface of the mounting groove 23; a second push block 16 is fixedly connected to the top of the push-pull rod 14, and the second push block 16 is attached to the left protrusion on the clip 17, and the height of the second push block 16 is greater than the gap height between the left protrusion on the clip 17 and the bottom surface of the mounting groove 23, and the side surfaces of the left and right protrusions are provided with inclined surfaces.

[0030] It can be understood that when the collection net bag 20 is filled with floating objects on the water surface, the push-pull rod 14 can be pulled to drive the second push block 16 to squeeze the clamping part 17. After the clamping part 17 is squeezed, the second spring 18 contracts to drive the clamping part 17 to lift and stop the clamping limit of the installation frame 19. Then the push-pull rod 14 can pull the installation frame 19 through the second push block 16 to slide out of the installation groove 23, allowing the staff to recycle and clean the collection net bag 20 on the shore. When it is necessary to install the cleaned collection net bag 20, the staff can place the installation frame 19 between the first push block 15 and the second push block 16, and then insert them into the interior of the installation groove 23 together, and then push the push-pull rod 14 to make the push-pull rod 14 push the installation frame 19 to move to the middle of the installation groove 23 through the first push block 15. When the installation frame 19 moves to a certain distance, the second push block 16 will first squeeze the clamping part 17 to lift it, and then continue to push the push-pull rod 14 to make the installation frame 19 directly below the clamping part 17. At this time, the second spring 18 extends to drive the clamping part 17 to fall to clamp and limit the installation frame 19, so that the staff can disassemble and install the collection net bag 20 on the shore.

[0031] Furthermore, a fixing groove is opened on the side of the support frame 101, and a fixing member 21 is slidably connected in the fixing groove; by slidably connecting the fixing member 21 to the support frame 101, the support frame 101 can rise or fall with the horizontal plane driven by the floating airbag 13 to adapt to the water height.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
