Description

Technical Field

[0001] The present invention belongs to the technical field of drainage of garbage pool grille plates, and particularly relates to a dredging device and method for a leachate grille plate of a garbage pool with superposed and combined dredging modules. Background Art

[0002] The space between the leachate channels of the garbage pool belongs to a finite element space, where there are toxic, harmful, flammable and explosive gases and corrosive turbid water. Moreover, the strength and thickness of the garbage pool grille plates are limited, and they are prone to sway left and right under the impact of external forces during use. Therefore, the existing mechanical dredging equipment is relatively heavy and has a large dredging force. It must be fixed on the garbage pool wall or directly use a concrete foundation as a reference. The working force is transferred to the garbage pool wall through a cross beam, and the weight is transferred to the ground through the lower support. It cannot be directly fixed on the grille plate, and its weight and the force during operation are unbearable for the grille plate. Although fixing the equipment on the concrete foundation or the pool wall can effectively fix the dredging device, it is necessary to ensure that the through columns of the dredging device are accurately aligned with the grille plate holes during installation. However, due to the swaying of the grille plate, it is easy to cause the through columns of the dredging device to be unable to be accurately aligned with the grille plate holes, directly affecting the normal use of the dredging device. To solve this problem, the prior art often needs to replace the garbage pool grille plate with increased thickness and strength while installing the dredging device. Since the environment in the garbage pool is complex and harsh, the material requirements for the garbage pool grille plate are high. Therefore, the thickened and strengthened garbage pool grille plate will greatly increase the construction cost and subsequent maintenance cost. In addition, early-built waste power plants usually did not consider the lifting device for equipment to enter the channel. Mechanical dredging equipment is mostly transported to the channel manually through stairs, which is difficult. The channel belongs to a confined space, and open flames and conventional electrical equipment cannot be used, directly resulting in the inability to use conventional lifting equipment. The equipment is completely installed by manpower, with great installation difficulty. Later maintenance also relies entirely on manual disassembly and transportation of equipment spare parts, making maintenance difficult.

[0003] The prior art with the publication number CN108744638A discloses a capsule-type leachate grille plate dredging device for a garbage pool, including a guide rail assembly fixed relative to the leachate grate plate. An intermediate frame is fixed on the guide rail assembly, and a through rod row and an outer side plate are also provided on the guide rail assembly. Both the through rod row and the outer side plate can slide along the guide rail. The through rod row and the outer side plate are located on both sides of the intermediate frame and are connected into one body by a connecting plate. The through rod row is arranged on the side close to the leachate grate plate. Water bags are provided between the through rod row and the intermediate frame and between the intermediate frame and the outer side plate. The water bags are respectively connected to a water inlet pipe and a water outlet pipe, and the water inlet and outlet of the water bags are controlled by a water valve assembly. Cylinders matching the grille plate holes of the leachate grate plate are provided on the through rod row. It relies on the water bag for operation, but the water bag material is easily damaged and aged, needs to be replaced frequently, and the overall structure is large and bulky, and cannot be used only in a limited space, with poor versatility.

[0004] The prior art with the publication number CN217996816U discloses a dredging device for the leachate grille plate of a garbage storage bin. Among them, the dredging device for the leachate grille plate of the garbage storage bin is provided corresponding to the grille plate with long strip-shaped through holes. The dredging device includes a support frame, a pressing plate arranged on the support frame, and a driving mechanism for driving the pressing plate to move. The pressing plate is arranged corresponding to the grille plate and one end of the pressing plate is hinged to the support frame. The pressing plate is connected to the driving mechanism, and the pressing plate makes a sector-shaped trajectory movement relative to the support frame around the hinge point under the control of the driving mechanism. A dredging member is arranged on the surface of the pressing plate corresponding to the grille plate. The dredging member is arranged corresponding to the long strip-shaped through holes on the grille plate, and the long strip-shaped through holes are dredged by the action of the dredging member on the long strip-shaped through holes. Its structure is simple, the dredging method is single and easy to be blocked by garbage, and it is also unable to cope with the dredging after the displacement of the grille plate. Summary of the Invention

[0005] In order to solve the problems existing in the above-mentioned prior art of the drainage system of the grille plate of the garbage pool, the present invention provides a dredging module superposition and combination type dredging device and method for the leachate grille plate of the garbage pool, which has a simple structure and is flexible to use. Its overall structure is tightly connected to the grille plate of the garbage pool, and even if the position of the grille plate changes during work, it can be ensured that it can always be dredged.

[0006] The present invention is realized by adopting the following technical solutions: The present invention discloses a dredging module superposition and combination type dredging device for the leachate grille plate of a garbage pool, which includes leachate grille plate dredging modules that are freely increased or decreased in number according to actual needs and arranged on the grille plate of the garbage pool. All the leachate grille plate dredging modules are combined into one body through spacing adjustment modules arranged on both sides, and the spacing between the leachate grille plate dredging modules is adjusted through the spacing adjustment modules to cope with different grille sizes; The leachate grille plate dredging module includes a dredging support module with a rectangular frame structure. A reciprocating linear pushing dredging power element is arranged inside the frame structure of the dredging support module. The tail of the reciprocating linear pushing dredging power element is movably connected to the dredging support module, and the other end is connected to a dredging execution module that can make a reciprocating movement for the grid of the grille plate; Each leachate grille plate dredging module can independently dredge the grille plate or can work together for dredging; All the leachate grille plate dredging modules are fixed on the grille plate through a pull rod device. When the position of the grille plate changes, all the leachate grille plate dredging modules always remain relatively stationary with the grille plate through the pull rod device, ensuring that the dredging support module can always work unobstructed.

[0007] Further, the dredging support module includes two dredging supports arranged in parallel. The front end of the dredging support is connected with a front guide plate, and the rear end is connected with a rear guide plate. Two positioning pin shafts for positioning the entire dredging support module on the grid plate are arranged inside the front end of the front guide plate. An ear seat a for pin connection with the reciprocating linear pushing dredging power element is arranged inside the rear end of the dredging support.

[0008] Further, the dredging execution module includes a frame-shaped structure with a size matching the inner space of the dredging support module. Multiple through columns for dredging the grid plate are fixedly arranged at equal intervals at the front end of the frame-shaped structure. An ear seat b for connecting with the end of the piston rod of the reciprocating linear pushing dredging power element is arranged at the middle position of the rear end. Two guide columns are respectively arranged in parallel on the upper and lower sides of the ear seat b. The tails of the two guide columns are matched with the guide holes formed on the rear guide plate to ensure the stable track during the reciprocating movement of the dredging execution module.

[0009] Further, the pull rod device includes a pull rod seat connected to the tail end of the dredging support module of the leachate grid plate dredging module. Pull rods for generating a pulling force on the leachate grid plate dredging module towards the grid plate are arranged between the left and right ends of the pull rod seat and the grid plate, and the position of the leachate grid plate dredging module is fixed through the pull rods.

[0010] Further, the pull rod includes a telescopically adjustable threaded lead screw. The threaded lead screw includes a threaded sleeve. The front and rear ends of the threaded sleeve are respectively connected with a lead screw II and a lead screw I through threads. The lead screw I is connected with the pull rod seat, and the lead screw II is connected with a fastening device for fixing with the grid plate through a pin II.

[0011] Further, the fastening device includes a threaded shaft inserted into the grid of the grid plate. An anti - detachment plate and a nut for clamping the grid plate are arranged on the threaded shaft. The anti - detachment plate is fixed through a pin II, and the anti - detachment plate and nut structure are used to ensure that the anti - detachment plate will not become loose even when impacted by an external force such as a garbage grab.

[0012] Further, the leachate grid plate dredging device can be arranged parallel to the ground or perpendicular to the ground.

[0013] A method for dredging the leachate grid plate of a garbage pool with superimposed and combined dredging modules. Multiple groups of leachate grid plate dredging modules work independently. Different leachate grid plate dredging modules are respectively controlled by a computer for dredging work, including sequentially making each leachate grid plate dredging module take turns for dredging work, or making all leachate grid plate dredging modules work simultaneously, or only controlling the part of the leachate grid plate dredging modules corresponding to the water level in the garbage pool according to the water level and garbage situation in the garbage pool to achieve the best dredging and drainage effect. Beneficial effects

[0014] This device has a simple structure. Different numbers of leachate grille plate dredging modules can be selected for combination according to needs, and multiple groups of leachate grille plate dredging modules work independently or are controlled by a program, improving the flexibility of dredging control and reducing the dredging force that the leachate grille plate in the garbage pool needs to bear. The leachate grille plate dredging device for the garbage pool of this device is small in size and light in weight. At the same time, the dredging support module of this device is not only the main support frame of the leachate grille plate dredging device for the garbage pool, but also the guiding component of the through column and guiding column of the dredging execution module, greatly simplifying the overall structure and weight of the device. The through column and guiding column of the leachate grille plate dredging device for the garbage pool pass through the front and rear guiding plate holes of the dredging support module respectively and always remain in the holes without falling out. The front and rear guiding plate holes determine the forward and backward directions of the through column. At the same time, the front and rear guiding plates bear the weight of the dredging execution module and hold up the dredging execution module so that it will not fall downward. This device can be directly fastened to the leachate grille plate in the garbage pool and move along with the position of the grille plate, so as to always adapt to the drainage holes on the grille plate, ensuring that the drainage holes can be dredged regardless of how the position of the grille plate changes under normal circumstances. Moreover, the dredging force of a single leachate grille plate dredging device for the garbage pool is small and will not damage the grille plate. The through column of the leachate grille plate dredging device for the garbage pool of this device is both a dredging execution component and a guiding component. The through column passes through the front guiding plate hole and always remains in the hole without falling out. The front guiding plate hole determines the forward and backward directions of the through column. At the same time, the front guiding plate hole also supports the through column, that is, holds it up so that it will not fall downward. This device is small in size and light in weight, can be adaptively combined according to different garbage pool environments, is convenient for installation and use in limited spaces, can better adapt to the garbage pool structures under various environmental conditions, and has good versatility.

[0027] The following further describes the embodiments of the present invention with reference to the accompanying drawings: As Figure 1 shown, the present invention discloses a leachate grille plate dredging device for a garbage pool with a superimposed combination of dredging modules. The device adopts a modular design method, decomposes the leachate grille plate dredging device for a garbage pool into multiple leachate grille plate dredging modules with independent dredging functions, and combines them into a whole by superimposing a pull rod and a pitch adjustment module; when the size of the leachate grille plate of the garbage pool is small, a group of leachate grille plate dredging modules can also be used; multiple leachate grille plate dredging modules respectively complete the dredging work of dredging the holes of the leachate grille plate of the garbage pool, effectively reducing the strength requirements for the leachate grille plate for installing multiple sets of leachate grille plate dredging modules.

The tail of the reciprocating linear pushing dredging power element 3 is movably connected to the dredging support module 1, and the other end is connected to a dredging execution module 2 that can perform reciprocating motion against the grid of the grille plate 8; each leachate grille plate dredging module can independently dredge the grille plate 8 or work cooperatively.

[0030] All leachate grille plate dredging modules are fixed on the grille plate 8 through a tie rod device. When the position of the grille plate 8 changes, all leachate grille plate dredging modules always remain relatively stationary with the grille plate 8 through the tie rod device, ensuring that the dredging support module 1 can always work unobstructed.

[0031] As Figure 3 、 Figure 4 shown, the dredging support module includes a dredging support 1-1, an ear seat a 1-4, a front guide plate 1-2, a rear guide plate 1-5, and a positioning pin 1-3; the front guide plate 1-2 is arranged on one side of the dredging support near the positioning pin 1-3, the rear guide plate 1-5 is arranged on the side far from the positioning pin 1-3, tie rod seats 7 are distributed on both sides of the dredging support 1-1, the tie rod seats 7 have through holes for the tie rods to pass through, the tie rod seats 7 are distributed on both sides of the dredging support, and the tie rod seat 1-1 has through holes for the tie rods to pass through; the dredging support module 1 includes two parallel dredging supports 1-1. The front end of the dredging support 1-1 is connected to a front guide plate 1-2, and the rear end is connected to a rear guide plate 1-5. Inside the front end of the front guide plate 1-2, there are two positioning pins 1-3 for positioning the entire dredging support module 1 on the grille plate 8. Inside the rear end of the dredging support 1-1, there is an ear seat a 1-4 for pin connection with the reciprocating linear pushing dredging power element 3; As Figure 5 shown, the dredging execution module includes a frame-shaped frame, a through column, a guide column, and an ear seat; one end face of the frame-shaped frame has a set of through column mounting holes, and the corresponding end face has guide column mounting holes and ear seats; the through column is assembled in the through column mounting holes of the frame-shaped frame, and the guide column is assembled in the guide column mounting holes of the frame-shaped frame; As Figure 2 shown, the reciprocating linear pushing dredging power element is assembled on the ear seat of the dredging support module through a pin at one end and on the ear seat of the frame-shaped frame of the dredging execution module at the other end; As Figures 6 - 8 shown, the pull rod includes an anti - detachment plate 6 - 1, a pin shaft I 6 - 2, a threaded shaft 6 - 3, a nut, a lead screw I, a threaded sleeve, a lead screw II, and a pin shaft II.

One end is inserted into the hole of the pull rod seat 7 on the dredging support module, and the pull rod seat 7 is directly welded to the dredging support module 1. The pull rod 6 fixes multiple groups of leachate grille plate dredging modules on the leachate grille plate; As Figure 1 shown, when the leachate grille plate device of the garbage pool works, the reciprocating linear pushing and pulling dredging power element pushes the dredging execution module 1 towards the grille plate 8. The front end of the through - column passes through the grille plate hole, and then the reciprocating linear pushing and pulling dredging power element pulls the dredging execution module away from the grille plate 8. The front end of the through - column withdraws from the grille plate hole, completing the dredging work of the leachate grille plate hole in the pool; When the leachate grille plate dredging device of the garbage pool works, each leachate grille plate dredging module can independently complete the dredging work of the leachate grille plate hole in the garbage pool, or can complete the dredging work of the grille plate hole through program control.
