Description

Technical Field

[0001] The invention relates to a float mechanism for collecting reservoir scum, belonging to the technical field of scum collecting equipment. Background Art

[0002] A reservoir is a modern civil engineering project that stores water and energy. It is categorized by size as small, medium, or large. Modern reservoirs are often built by taking advantage of terrain, nestled against mountains and near waterways. Therefore, open-air reservoirs are common. Due to their prolonged exposure to the elements, the water within them often contains a large amount of scum floating on its surface. This scum, if left for too long, can affect water quality and lead to the proliferation of bacteria and viruses.

[0003] Therefore, a common practice is for workers to use long poles and net bags for salvage. However, this process often requires a lot of manpower and materials, is time-consuming, and because it is manual salvage, it is difficult to salvage the scum on the water surface, resulting in low work efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a float mechanism for collecting reservoir scum, which uses machinery to replace manual work, reduces labor costs, improves work efficiency, and can salvage the scum on the water surface.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0006] A float mechanism for collecting reservoir scum, comprising:

[0007] The shell has an open top and a sawtooth edge at the opening, and water inlets are symmetrically provided at both ends of the shell, and the water inlets are located below the sawtooth gaps;

[0008] Sliding plates are placed at both ends of the shell and slide up and down with the water level. The sliding plates can cover the water inlet. The sliding plates are provided with an opening, and a float is provided above the opening.

[0009] Duckweed components are fixed around the shell;

[0010] A pump body, fixed inside the housing;

[0011] The scum collecting box is placed at the bottom of the shell and is connected with the pump body through a pipeline.

[0012] In the present invention, a float mechanism is placed on the water surface of a reservoir, and the pump body is turned on to operate. Because duckweed components are placed around the housing, the float mechanism can float on the water surface. When the water level is near the water inlet of the housing, the opening on the sliding plate aligns with the water inlet. At this point, scum floating on the water surface, under the action of the pump body's suction, flows from the outside of the housing through the water inlet and the opening on the sliding plate into the housing, and finally collects in the scum collection box through the pump body. When the water level is too high (i.e., the water level can drive the float upward, thereby driving the sliding plate upward, causing the opening on the sliding plate to shift away from the water inlet until the opening on the sliding plate is lifted to the middle position of the sawtooth structure), high water can flow into the gap between the sawtooth structure and the opening, driving scum on the water surface into the housing, and ultimately reaching the scum collection box. The operator can place multiple float mechanisms according to the area of ​​the reservoir. After the scum on the water surface is collected, the scum collection box can be cleaned centrally. The present invention utilizes machinery to replace manual labor, reduces labor costs, improves work efficiency, and can salvage the scum on the water surface.

[0013] Preferably, limit bars are provided on both sides of the water inlet, and the sliding plate is placed between the limit bars and slides up and down according to the water level.

[0014] The limiting strips on both sides provide space for the sliding plate to float up and down, and at the same time, can limit the sliding plate from falling off from the side end of the shell.

[0015] Preferably, an oblique plate is welded above the opening, and the float is fixed on the oblique plate.

[0016] The inclined plate provides support for the float. At the same time, the inclined plate and the sliding plate form an acute angle, so that the buoyancy can act on the float quickly, avoiding the sliding plate from getting stuck during the floating process.

[0017] Preferably, a through hole is provided on one side of the shell adjacent to the water inlet, a transverse support rod is installed in the through hole, a longitudinal support rod is fixedly connected to the transverse support rod, and the pump body is mounted at the intersection of the transverse support rod and the longitudinal support rod.

[0018] The horizontal and vertical staggered horizontal support rods and longitudinal support rods can provide good support for the pump body, preventing the impact of water waves during the water intake process from affecting the stability of the pump body.

[0019] Preferably, the pump body is provided with two mutually fixed semicircular arc clamps, and a plurality of support plates are distributed circumferentially on the outer surface of the semicircular arc clamp. The support plates are overlapped at the intersection of the transverse support rod and the longitudinal support rod and are fixedly connected to each other.

[0020] A plurality of support plates distributed around the circumference can evenly distribute the support force on the two mutually fixed semicircular arc-shaped clamping surfaces, thereby preventing the pump body from deflecting.

[0021] Preferably, a filter screen is suspended above the pump body.

[0022] The filter cover can isolate large floating impurities from the pump pipeline, thereby preventing large garbage from clogging the pump pipeline.

[0023] Preferably, the duckweed assembly includes a connection block fixed to the bottom of the shell, a screw is longitudinally fixed to the connection block, and at least one float is fixedly connected to the screw.

[0024] In the present invention, the buoyancy of the float mechanism is mainly achieved by floats, and the operator can increase or decrease the number of floats according to the outer dimensions of the float mechanism.

[0025] The beneficial effects of the present invention are:

[0026] In the present invention, a float mechanism is placed on the water surface of a reservoir, and the pump body is turned on to operate. Because duckweed components are placed around the housing, the float mechanism can float on the water surface. When the water level is near the water inlet of the housing, the opening on the sliding plate aligns with the water inlet. At this point, scum floating on the water surface, under the action of the pump body's suction, flows from the outside of the housing through the water inlet and the opening on the sliding plate into the housing, and finally collects in the scum collection box through the pump body. When the water level is too high (i.e., the water level can drive the float upward, thereby driving the sliding plate upward, causing the opening on the sliding plate to shift away from the water inlet until the opening on the sliding plate is lifted to the middle position of the sawtooth structure), high water can flow into the gap between the sawtooth structure and the opening, driving scum on the water surface into the housing, and ultimately reaching the scum collection box. The operator can place multiple float mechanisms according to the area of ​​the reservoir. After the scum on the water surface is collected, the scum collection box can be cleaned centrally. The present invention utilizes machinery to replace manual labor, reduces labor costs, improves work efficiency, and can salvage the scum on the water surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Example 1

[0036] like Figure 1-Figure 5 As shown, a float mechanism for collecting scum in a reservoir comprises: a shell 1, a sliding plate 2, a duckweed assembly 4, a pump body 5, and a scum collection box 6; wherein the top of the shell 1 is open, and the edge of the opening is a serrated structure, and water inlets 11 are symmetrically provided at both ends of the shell 1, and the water inlet 11 is located below the serrated notch; the sliding plate 2 is placed at both ends of the shell 1 and slides up and down with the water level, and the sliding plate 2 can cover the water inlet, and an opening 21 is provided on the sliding plate 2, and a float 3 is provided above the opening 21; the duckweed assembly 4 is fixed to the four sides of the shell 1; the pump body 5 is fixed inside the shell 1; the scum collection box 6 is placed at the bottom of the shell 1 and is connected to the pump body 5 through a pipeline.

[0037] In the present invention, the float 3 is placed on the surface of the reservoir, and the pump 5 is turned on to operate. Because the duckweed assembly 4 is placed around the housing 1, the float 3 is able to float on the water surface. When the water level is near the water inlet 11 of the housing 1, the opening 21 on the sliding plate 2 corresponds to the water inlet 11. At this time, under the suction of the pump body 5, scum floating on the water surface enters the housing 1 from the outside through the water inlet 11 and the opening 21 on the sliding plate 2, and finally passes through the pump body 5 and is collected in the scum collection box 6. When the water level is too high (i.e., the water level can drive the float 3 upward, thereby driving the sliding plate 2 upward, causing the opening 21 on the sliding plate 2 to be offset from the water inlet 11 until the opening 21 on the sliding plate 2 is lifted to the middle position of the zigzag structure), the high water level can flow into the gap between the zigzag structure and the opening 21, thereby driving scum on the water surface into the housing 1 and ultimately reaching the scum collection box 6. The operator can place multiple floats 3 according to the area of ​​the reservoir, and after the scum on the water surface is collected, the scum collection box 6 can be cleaned centrally. The present invention uses machinery to replace manual work, reduces labor costs, improves work efficiency, and can salvage the scum on the water surface.

[0038] Specifically, limit bars 7 are welded on both sides of the water inlet 11. The sliding plate 2 is placed between the limit bars 7 and slides up and down with the water level. The limit bars 7 on both sides provide space for the sliding plate 2 to float up and down, and at the same time, they can prevent the sliding plate 2 from falling off the side ends of the housing 1.

[0039] Among them, the housing 1 is provided with a through hole on a side adjacent to the water inlet 11, in which a transverse support rod 8 is installed. The transverse support rod 8 is fixedly connected to the longitudinal support rod 9. The pump body 5 is mounted at the intersection of the transverse support rod 8 and the longitudinal support rod 9. The transverse support rods 8 and the longitudinal support rods 9 arranged in a staggered manner can provide good support for the pump body 5, preventing the impact of water waves from affecting the stability of the pump body 5 during the water intake process.

[0040] The duckweed assembly 4 includes a connecting block 41 fixed to the bottom of the housing 1. A screw 42 is longitudinally fixed to the connecting block 41. At least one float 43 is fixedly connected to the screw 42 via a nut 44. (In this embodiment, two floats are provided at one corner of the housing, and the same number of floats are provided at all four corners of the housing.) In the present invention, the buoyancy of the float 3 mechanism is primarily achieved through the floats 43. The operator can increase or decrease the number of floats 43 based on the external dimensions of the float 3 mechanism.

[0041] Example 2

[0042] Based on Example 1, Figure 2An inclined plate 22 is welded above the opening 21, and the float 3 is fixed on the inclined plate 22. The inclined plate 22 provides support for the float 3. At the same time, the inclined plate 22 forms an acute angle with the sliding plate 2, so that its buoyancy can act quickly on the float 3, avoiding the sliding plate 2 from getting stuck during the floating process.

[0043] Example 3

[0044] Based on Example 1, Figure 4-Figure 5 The pump body 5 is provided with two mutually fixed semicircular arc-shaped clamps 10. Several support plates 101 are distributed circumferentially around the outer surface of the semicircular arc clamps 10. The support plates 101 overlap the intersection of the transverse support rods 8 and the longitudinal support rods 9 and are fixedly connected to each other. The circumferential distribution of the support plates 101 evenly distributes the supporting force across the surfaces of the two mutually fixed semicircular arc clamps 10, preventing the pump body 5 from shifting.

[0045] A filter screen cover 12 is suspended above the pump body 5. The filter screen cover 12 can isolate large floating impurities outside the pump body 5 pipelines, thereby preventing large garbage from clogging the pump body 5 pipelines.

Those skilled in the art will appreciate that the present invention is not limited to the foregoing embodiments and that various modifications and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
