Description

Technical Field

[0001] The utility model relates to the technical field of garbage pools, and in particular to an intelligent garbage pool seepage liquid dredging robot. Background Art

[0002] In the waste incineration power plants that have been built, the garbage storage basically adopts deep pits with flat bottoms and trenches to collect leachate, but the leachate collection effect is very unsatisfactory. The leachate is highly concentrated, viscous, and flows slowly. In addition, the debris, plastics, etc. that slide to the bottom of the garbage pool will also affect the directional flow of the leachate, and even block the leachate grid plate, resulting in the leachate cannot be discharged in time, so it needs to be cleared regularly.

[0003] The garbage pool contains strong carcinogens (dioxins, etc.), acidic gases and flammable and explosive gases (methane, etc.). At the same time, the leachate is a special organic wastewater with a high concentration of pollutants, complex water quality and a strong odor, which can cause dizziness, nausea, hematuria and other symptoms. There have been poisoning and suffocation accidents in the leachate rooms of many garbage power plants in China, causing many casualties. Therefore, automated equipment is generally used to drive the plug rod to dredge the drain holes.

[0004] However, since there is a lot of leachate in the garbage pool, the drain hole cannot discharge the liquid to the outside when the rod is inserted into the drain hole. When the rod is moved out of the drain hole, the leachate in the garbage pool will be discharged through the drain hole, and will quickly carry the garbage to block the drain hole again. Therefore, the rod needs to be inserted into the drain hole multiple times for dredging, which consumes a lot of energy. Utility Model Content

[0005] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the utility model is to provide an intelligent garbage pool seepage liquid dredging robot to facilitate the discharge of the seepage liquid and reduce the energy consumption of the equipment.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an intelligent garbage pool leachate dredging robot, comprising a garbage pool, a leachate grid is arranged on the side wall of the garbage pool, a drainage hole is opened on the side wall of the leachate grid, a plug rod for dredging the drainage hole is arranged on the outside of the garbage pool, a bearing plate is fixedly installed on the side of the plug rod away from the drainage hole, and a first driving member is installed on the side of the bearing plate away from the plug rod;

[0007] A cavity is provided in the insertion rod, and a connecting rod is rotatably installed in the cavity. The cross-section of the connecting rod is semicircular, and a strip opening connected to the cavity is provided on the lower side of the insertion rod. A second driving member for driving the connecting rod to rotate is installed on the supporting plate. In the initial state, when the arc surface of the rod is located at the strip opening, the connecting rod blocks the strip opening.

[0008] The first driving member is a hydraulic cylinder, and a moving end of the hydraulic cylinder is connected to a bearing plate.

[0009] The second driving member comprises an electric slide rail fixedly mounted on the bearing plate, an electric slider is slidably arranged on the electric slide rail, a rack is fixedly mounted on the electric slider, and a gear meshing with the rack is fixedly mounted on one end of the connecting rod.

[0010] A pressure sensor is installed on the bearing plate, an auxiliary plate for squeezing the pressure sensor is installed on the bearing plate, the auxiliary plate and the bearing plate are connected via a telescopic rod, and the hydraulic cylinder is fixedly connected to the auxiliary plate.

[0011] It also includes a frame fixedly installed on the side wall of the garbage pool, and a travel switch is arranged on the frame.

[0012] Compared with the prior art, the utility model has the following beneficial effects: after the insertion rod is inserted into the drain hole, part of the strip-shaped opening is located outside the garbage pool, and then the connecting rod is driven to rotate by the second driving member, so that the connecting rod rotates, the blockage of the strip-shaped opening is released, the strip-shaped opening is connected with the cavity, and a drainage channel is formed on the lower side of the insertion rod, and the leachate in the garbage pool can flow to the outside of the garbage pool through the drainage channel, so that the leachate in the garbage pool can still be discharged when the insertion rod is inserted, and at the same time, the strip-shaped opening is located on the lower side of the insertion rod, so that the garbage will be carried by the insertion rod, prolonging the blocking time of the strip-shaped opening, wherein the insertion rod stays in the drain hole for a period of time, on the one hand, the liquid is discharged through the insertion rod, and on the other hand, the insertion rod stays for a long time, and under the interaction force after the garbage in the garbage pool is squeezed, when the insertion rod is pulled out, the formed channel will not collapse quickly, which is convenient for drainage, and at the same time reduces the number of reciprocating times of the overall dredging of the insertion rod, saving energy.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1 and Figure 2 As shown in the figure, this embodiment provides an intelligent garbage pool leachate dredging robot, including a garbage pool 1. A liquid level detection system is arranged in the garbage pool 1, and a controller is further included. A leachate grille 11 is arranged on the side wall of the garbage pool, a drainage hole 2 is opened on the side wall of the leachate grille 11, and an insertion rod 3 for dredging the drainage hole 2 is arranged outside the garbage pool 1. A bearing plate 4 is fixedly installed on the side of the insertion rod 3 away from the drainage hole 2, a first driving member 5 is installed on the side of the bearing plate 4 away from the insertion rod 3, and both the first driving member 5 and the liquid level control system are electrically connected to the controller.

[0021] When the drainage hole 2 of the garbage is blocked, at this time, the leachate in the garbage pool 1 cannot be discharged externally. Therefore, the liquid content of the leachate in the garbage pool 1 will increase over time, and the liquid level will rise, which is detected by the liquid level detection system. The liquid level detection system transmits an electrical signal to the controller, and the controller controls the first driving member 5 to drive the bearing plate 4 to move towards the drainage hole 2, thereby driving the insertion rod 3 to insert into the drainage hole 2. The garbage blocking the drainage hole 2 is pushed and extruded by the insertion rod 3, so that the garbage in the drainage hole 2 moves into the garbage pool 1. The insertion rod 3 continues to move and extends into the garbage pool 1 for a certain distance to achieve the dredging effect. Then, the first driving member 5 drives the insertion rod 3 to move in the reverse direction through the bearing plate 4, so that the insertion rod 3 is removed from the drainage hole 2, thereby dredging the drainage hole 2, and the leachate can be discharged from the drainage hole 2, playing a role in dredging the drainage hole 2.

[0022] However, because there is a large amount of leachate in the garbage pool 1, when the insertion rod 3 inserts into the drainage hole 2, the drainage hole 2 cannot drain liquid externally. When the insertion rod 3 is removed from the drainage hole 2, during the process of discharging the leachate in the garbage pool 1 through the drainage hole 2, the leachate will quickly carry the garbage to block the drainage hole 2 again. Therefore, the insertion rod 3 needs to be inserted into the drainage hole 2 multiple times, consuming a large amount of energy.

[0023] Please refer toFigure 2 and Figure 3 To solve the above technical problems, a cavity 31 is provided in the inserting rod 3, a connecting rod 32 is rotatably installed in the cavity 31, the cross-section of the connecting rod 32 is semi-circular, a strip-shaped opening 33 communicating with the cavity 31 is provided on the lower side of the inserting rod 3, a second driving member 34 for driving the connecting rod 32 to rotate is installed on the bearing plate 4, the second driving member 34 is electrically connected to the controller, and in the initial state, when the arc-shaped surface of the rod is located at the strip-shaped opening 33, the connecting rod 32 blocks the strip-shaped opening 33.

[0024] After the inserting rod 3 is completely inserted into the hydrophobic hole 2, a part of the strip-shaped opening 33 on the inserting rod 3 is located outside the garbage pool 1 (that is, outside the hydrophobic hole 2), and then the second driving member 34 drives the connecting rod 32 to rotate, so that the connecting rod 32 releases the blockage of the strip-shaped opening 33, making the part of the inserting rod 3 at the strip-shaped opening 33 change from a near-cylindrical shape to a semi-cylindrical shape (that is, from Figure 3 become Figure 4 ), so as to form a drainage channel on the lower side of the inserting rod 3, and the leachate in the garbage pool 1 can flow to the outside of the garbage pool 1 through the drainage channel, realizing the discharge of the leachate in the garbage pool 1 even after the inserting rod 3 is inserted. The inserting rod 3 stays in the hydrophobic hole 2 for a period of time. On the one hand, the liquid is discharged through the inserting rod 3. On the other hand, when the inserting rod 3 stays for a long time, under the mutual acting force of the garbage in the garbage pool 1 being squeezed, when the inserting rod 3 is pulled out, the formed channel will not collapse quickly, which is convenient for liquid discharge, reduces the dredging times of the inserting rod 3, and saves energy consumption.

[0025] Please refer to Figure 2 , the first driving member 5 is a hydraulic cylinder, and the moving end of the hydraulic cylinder is connected to the bearing plate 4. The bearing plate 4 is pushed to move by the hydraulic cylinder.

[0026] Please refer to Figure 2 and Figure 3 , the second driving member 34 includes an electric slide rail 35 fixedly installed on the bearing plate 4, an electric slider 36 is slidably arranged on the electric slide rail, a rack 37 is fixedly installed on the electric slider 36, and a gear 38 meshing with the rack 37 is fixedly installed at one end of the connecting rod 32, and one end of the connecting rod 32 close to the gear 38 passes through the bearing plate 4. When the inserting rod 3 reaches the preset position, the controller controls the electric slider 36 to slide, thereby driving the rack 37 to move, and then driving the connecting rod 32 to rotate through the meshing of the rack 37 and the gear 38.

[0027] Please refer to Figure 2 and Figure 3 , to protect the inserting rod 3 from being damaged due to too much pressure when inserted. A pressure sensor 6 is installed on the bearing plate 4, the pressure sensor 6 is electrically connected to the controller, an auxiliary plate 7 for pressing the pressure sensor 6 is installed on the bearing plate 4, the auxiliary plate 7 and the bearing plate 4 are connected by a telescopic rod 8, and the hydraulic cylinder is fixedly connected to the auxiliary plate 7.

[0028] During the movement of the auxiliary plate 7 and the bearing plate 4 driven by the hydraulic cylinder, if the insertion rod 3 is blocked by garbage after being inserted into the hydrophobic hole 2, the reaction force of the garbage in the garbage pool 1 on the insertion rod 3 is relatively large, resulting in the blockage of the insertion rod 3. At this time, since the telescopic rod 8 is provided between the auxiliary plate 7 and the bearing plate 4, the distance between the auxiliary plate 7 and the bearing plate 4 is reduced, so that the auxiliary plate 7 and the bearing plate 4 jointly apply pressure to the pressure sensor 6. When the pressure detected by the pressure sensor 6 reaches the preset value, the pressure sensor 6 transmits an electrical signal to the controller, and the controller controls the hydraulic cylinder to contract, moving the auxiliary plate 7, the bearing plate 4 and the insertion rod 3 away from the garbage pool 1, and then reinserting them into the garbage pool 1 to reduce the situation of the insertion rod 3 being damaged due to excessive pressure.

[0029] Please refer to Figure 1 , and it further includes a frame 9 fixedly installed on the side wall of the garbage pool 1, and a travel switch 10 is arranged on the frame 9. Through the travel switch 10, it is possible to monitor whether the dredging action of the insertion rod 3 is carried out in place.

[0030] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
