Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0031] Refer to Figure 1 , Figure 2 and Figure 6, an embodiment provided by the present utility model: a leech breeding silt cleaning device and a leech capturing device, including a base 1, which is used to stably support the equipment components. At the same time, rollers are provided at the bottom to facilitate the movement of the equipment. At the right top end of the base 1, there is a silt collection box 2 for collecting silt. A hatch is provided at its front end to facilitate the cleaning of silt. A top cover 3 is provided at the top of the silt collection box 2 to seal the silt collection box 2, thereby providing a sealed environment. A first connecting pipe 4 for connecting the silt collection box 2 and a three-way valve 5 is fixedly connected through the top of the top cover 3 to convey silt and water. At the left bottom end of the first connecting pipe 4, there is a three-way valve 5. The bottom end of the three-way valve 5 is fixedly connected through the top of the capturing box 91 to connect the first connecting pipe 4, the capturing box 91 and a suction pipe 10, enabling the substances or fluids from the suction pipe 10 to have different flow direction choices, so as to separate silt cleaning from capturing. The three-way valve 5 is a prior art, so it will not be described in detail in this case. A suction pipe 10 is provided on the left side of the three-way valve 5 for sucking silt or capturing leeches. A silt cleaning component is provided on the inner wall of the silt collection box 2. The silt cleaning component includes a rotating cylinder 71 driven by water flow and silt. The left and right sides of the rotating cylinder 71 are rotatably connected to the inner wall of the top cover 3. Blades are provided on the inner wall of the rotating cylinder 71. Multiple groups of blades are provided, and the multiple groups of blades are set as arcs. The arc openings of the blades face the right bottom end of the first connecting pipe 4. By the impact of water flow and silt on the arc openings of the blades, the rotating cylinder 71 can rotate stably. A first bevel gear 72 is fixedly connected to the right side of the rotating cylinder 71. By driving the first bevel gear 72 to rotate through the rotating cylinder 71, the second bevel gear 73 is driven to rotate.
[0032] Refer to Figure 2 and Figure 3, on the right bottom end of bevel gear 1 72, there is a meshing bevel gear 2 73 that drives the cleaning brush 74 to rotate. At the bottom end of bevel gear 2 73, there is a fixedly connected cleaning brush 74 for cleaning the filter barrel 75. The inner wall of the bottom end of cleaning brush 74 is rotatably connected to the filter barrel 75. The filter holes near the left side of the filter barrel 75 in the mounting plate 76 are larger than the filter holes on the right side. Secondary filtration can be achieved through the filter barrel 75, thus realizing the dual guarantee and improvement of water quality. The bottom end of the filter barrel 75 fits against the inner wall of the bottom side of the sludge collection box 2. The outer side of the cleaning brush 74 is provided with bristles, and the bristles are arranged in a spiral shape. The bristles slide on the inner wall of the filter barrel 75, which can prevent the sludge from blocking the filter barrel 75, effectively preventing the occurrence of blockage problems and ensuring the unobstructed water circulation. The left outer wall of the filter barrel 75 is fixedly connected to the mounting plate 76, which can fix the filter barrel 75 in the sludge collection box 2 and is convenient for maintenance at the same time. The front and rear outer walls of the mounting plate 76 are inserted into the inner wall of the sludge collection box 2. On the upper side of the right end of the sludge collection box 2, there is a fixedly connected push rod, which can push the equipment to move, thereby improving the flexibility of the equipment. The right bottom end of the connecting pipe 1 4 is arranged near the rear side of the rotating cylinder 71, so that the negative pressure generated by the water pump 6 during operation can drive the muddy water to impact the blades on the rotating cylinder 71, thereby driving the rotating cylinder 71 to rotate. On the inner wall of the right bottom end of the sludge collection box 2, there is a water pump 6. The water pump 6 is used to generate negative pressure inside the sludge collection box 2 to suck the muddy water. The water inlet of the water pump 6 is arranged on the inner wall of the sludge collection box 2, and the water outlet of the water pump 6 is arranged on the lower side of the right end of the sludge collection box 2, which is used to suck the filtered pool water and then discharge it through the water outlet.
[0033] Refer to Figure 4 - Figure 6, the present utility model provides a leech capture device, including a second connecting pipe 8, which is used to connect the upper cover 3 and the capture box 91, and convey the pond water sucked together with the leeches when sucking the leeches. The right bottom end of the second connecting pipe 8 runs through and is fixedly connected to the top end of the upper cover 3. A capture assembly is arranged on the left side of the second connecting pipe 8. The capture assembly includes a capture box 91. The leeches and pond water sucked from the suction pipe 10 enter the capture box 91 through a three-way valve 5. The bottom end of the capture box 91 is fixedly connected to the top left end of the base 1. The left side of the second connecting pipe 8 runs through and is fixedly connected to the rear side of the capture box 91 to convey the pond water sucked together with the leeches when sucking the leeches. A collection basket 92 is arranged on the inner wall of the capture box 91. The leeches sucked by the suction pipe 10 will fall into the collection basket 92 for collection. A limiting plate 93 for limiting the collection basket 92 is slidably connected to the front inner wall of the collection basket 92. A limiting groove 95 is opened on the right side of the capture box 91 near the limiting plate 93. By cooperating with the limiting plate 93, the collection basket 92 can be quickly and easily removed, improving the convenience and practicality of the device. The right side of the limiting plate 93 slides on the inner wall of the limiting groove 95. There are two groups of limiting plates 93. The two groups of limiting plates 93 are elastically connected by a return spring 94 to provide an elastic restoring force for the limiting plate 93, so that it maintains a certain position and state when not affected by external forces. A sealing gasket 96 is arranged on the top inner wall of the collection basket 92. The top of the sealing gasket 96 slides on the inner wall of the capture box 91 to prevent the leeches from climbing out of the collection basket 92.
[0034] Working principle: When in use, first move the device to a suitable position through the rollers at the bottom of the base 1, and start the water pump 6. When the water pump 6 works, a negative pressure is generated inside the silt collection box 2. Under the action of the negative pressure, the muddy water mixture is sucked into through the suction pipe 10. After the muddy water mixture enters the first connecting pipe 4, since the right bottom end of the first connecting pipe 4 is close to the rear side of the rotating cylinder 71 and the arc-shaped blades on the inner wall of the rotating cylinder 71 open towards the right bottom end of the first connecting pipe 4, the muddy water impacts the blades to make the rotating cylinder 71 rotate stably. The rotation of the rotating cylinder 71 drives the first bevel gear 72 to rotate. The first bevel gear 72 meshes with the second bevel gear 73 to drive the second bevel gear 73 to rotate. The cleaning brush 74 at the bottom end of the second bevel gear 73 rotates accordingly. The spiral bristles on the outside of the cleaning brush 74 slide on the inner wall of the filter barrel 75 to prevent the filter barrel 75 from being blocked by silt.
[0035] The filter barrel 75 is fixed in the silt collection box 2 through a mounting plate 76. The filter holes opened on its left side are larger and those on the right side are smaller, realizing secondary filtration and improving the water quality. The filtered muddy water remains in the silt collection box 2. The hatch at the front end of the silt collection box 2 facilitates the cleaning of the silt.
[0036] When it is necessary to capture leeches, the flow direction is switched through the three-way valve 5, so that the pool water and leeches enter the capture box 91 through the suction pipe 10. The leeches sucked by the suction pipe 10 will fall into the collection basket 92 on the inner wall of the capture box 91, thus realizing the rapid capture of leeches and improving the capture efficiency. When it is necessary to take out the leeches, by pulling the two groups of limit plates 93 at the front end of the collection basket 92, it slides out of the limit groove 95, so that the collection basket 92 can be quickly removed, improving the convenience and practicability of the equipment.
[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
