[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0028] The utility model provides a filtering and lifting device for cleaning debris, referring to Figure 1-Figure 4 ,include:

[0029] The upper opening of the receiving box 1 is used as an inlet for receiving sewage and garbage and as an outlet for centralized discharge and cleaning of garbage; a pumping hole 10 is provided at the bottom of the receiving box 1 to facilitate the discharge of sewage;

[0030] The filter screen plate 2 is arranged in the receiving box 1 and has a filter hole 20 therein for solid-liquid separation of sewage and garbage. The sewage seeps into the receiving box 1 through the filter hole 20 on the filter screen plate 2 and is discharged from the receiving box 1 through the pumping hole 10.

[0031] The lifting assembly 3 is arranged in the well chamber 4 and is used to lift the object box 1 to the exit of the well chamber 4. With this arrangement, the cleaning work does not need to be performed manually in the well chamber 4, which greatly reduces the difficulty of work and safety risks;

[0032] A linear drive assembly 5, disposed on the filter screen plate 2 to generate a reciprocating linear drive; and

[0033] The debris push plate 6 is movably arranged on the filter screen plate 2 ; and the debris push plate 6 cleans the garbage and debris on the filter screen plate 2 through the linear drive component 5 .

[0034] During the cleaning process, sewage can penetrate into the receiving box 1 through the filter holes 20 of the filter screen plate 2. The bottom of the receiving box 1 is provided with a pumping hole 10 to facilitate the discharge of sewage, while solid debris is left on the filter screen plate 2. The lifting component 3 is responsible for lifting the receiving box 1 to the exit of the well chamber 4. The debris push plate 6 can push the garbage and debris on the filter screen plate 2 to the outside of the well chamber 4 under the action of the linear drive component 5, which is convenient for centralized discharge. In this way, the wastewater and waste cleaning work is decomposed into two parts: centralized cleaning of solid debris and discharge of liquid water sources, and the cleaning efficiency is greatly improved. The sewage can be pumped out using devices such as water pumps. Traditional treatment methods often require manual cleaning, which is not only labor-intensive, but also has safety hazards; while the present device simplifies the cleaning operations of underground confined spaces such as pools, well chambers 4 and pump stations, greatly reduces the difficulty of manual cleaning, and decomposes the wastewater and waste cleaning work into two parts: centralized cleaning of solid debris and discharge of liquid water sources, thereby improving the efficiency of debris cleaning.

[0035] Reference Figure 3 The lifting component 3 includes a lifting track 31, a gear 32 and a rack 33. In the present embodiment, two lifting components 3 are provided, and the two lifting components 3 are correspondingly arranged on both sides of the object receiving box 1; the lifting track 31 is arranged on the inner wall of the well chamber 4 to play a bearing and guiding role, the gear 32 is rotatably connected to the lifting track 31, and the rack 33 is slidably connected to the lifting track 31 in the vertical direction and meshes with the gear 32, and the object receiving box 1 is fixedly connected to the lower end of the rack 33, wherein one end of the gear 32 is used for power input of an external power component such as a motor, and the gear 32 is responsible for transmitting the power of the motor to the rack 33 to realize the vertical movement of the object receiving box 1, when the motor rotates, the gear 32 will also rotate accordingly, thereby driving the rack 33 to slide in the vertical direction, so that the object receiving box 1 can vertically rise or fall in the well chamber 4 to meet the needs of various working conditions.

[0036] Reference Figure 4, a plurality of pulling members are symmetrically arranged on the filter screen plate 2, which are used to conveniently pull the filter screen plate 2 to the exit of the receiving box 1; wherein, the pulling member includes a pull ring 21 and a rope 22, the pull ring 21 is fixedly arranged on the filter screen plate 2, one end of the rope 22 is fixed on the pull ring 21, and the rope 22 extends out of the receiving box 1; in the process of pulling the rope 22, it can be operated with the help of external equipment, such as a manual winch, a pulley 61, etc., so that when pulling the filter screen plate 2, it is easier to control the strength and direction. In addition, the process of pulling the rope 22 can be done with the help of external equipment or manually, which fully takes into account the actual needs, making the filter screen plate 2 more flexible and convenient during use.

[0037] As an exemplary implementation of the linear drive assembly 5, the linear drive assembly 5 is configured as a cylinder. In this embodiment, two cylinders are provided, which are correspondingly arranged on the left and right sides above the filter screen plate 2, and the piston rods of the cylinders are fixedly connected to the debris push plate 6. Of course, the linear drive assembly 5 can also be in the form of an electric push rod or a hydraulic push rod.

[0038] In addition, the linear drive assembly 5 can also be arranged in the form of a screw slider structure. Here, it is well known to the technicians in the relevant field that the screw slider mechanism is composed of a screw with a thread and a slider screwed on the screw, and the slider has an internal thread, which matches the external thread of the screw. The slider is slidably mounted on the filter screen 2, and the slider is fixedly connected to the debris push plate 6. In addition, the self-rotation of the slider is not allowed. One end of the screw is used for power input of an external power component such as a motor. When the screw is rotated by an external force, the screw rotates, and the self-rotation of the slider is prohibited by screwing with the slider, thereby converting the rotation of the screw into a linear reciprocating motion of the slider, so that the slider drives the debris push plate 6 to do a linear reciprocating motion on the filter screen 2, and the garbage and debris on the debris push plate 6 are cleaned out of the well chamber 4.

[0039] In addition, a pulley 61 is provided at the bottom of the debris pushing plate 6, and a sliding guide pair 62 for the pulley 61 to slide is provided above the filter screen plate 2. The guide sliding pair is configured as a slide rail, and the pulley 61 can slide on the slide rail, so that the debris pushing plate 6 can more smoothly push the garbage and debris on the filter screen plate 2 to the outside of the carrying box and the well chamber 4, so as to avoid the situation where the cylinder piston rod is easily broken, thereby improving work efficiency.

[0040] A pressure sensor 11 is provided below the carrying box, and the rated pressure can be set according to the type of waste in the surrounding water body and the size of the receiving box 1. The initial position of the receiving box 1 is located above the pressure sensor 11, and the pressure sensor 11 is connected to a pressure gauge. A pressure gauge is provided in the control box. By observing the pressure gauge, it can be determined whether the weight of the solids in the receiving box 1 exceeds the rated pressure, so as to choose whether to lift and discharge the receiving box 1 for cleaning. The operation process of the entire filtering and debris lifting and discharging device is all automatically managed by the control system. While achieving environmental protection goals, it also greatly improves work efficiency and reduces labor costs.

[0041] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
