Description

Technical Field

[0001] This utility model belongs to the technical field of drainage of garbage pit gratings, specifically relating to a garbage pit leachate grating dredging device with superimposed dredging modules. Background Technology

[0002] The leachate channels in garbage dumps are finite element spaces containing toxic, harmful, flammable, and explosive gases, as well as corrosive turbid water. Furthermore, the strength and thickness of the garbage dump's grating are limited, making it susceptible to lateral swaying from external impacts during use. Therefore, existing mechanical dredging equipment, being heavy and possessing significant dredging force, must be fixed to the garbage dump wall or directly to a concrete foundation. The working force is transferred to the garbage dump wall via beams, and the weight is transferred to the ground via lower supports. Direct fixation to the grating is not feasible, as the weight and forces exerted during operation are beyond the grating's capacity. While fixing the equipment to a concrete foundation or dump wall effectively secures the dredging device, precise alignment of the device's guide post with the grating's holes is crucial during installation. However, the swaying of the grating can easily cause the dredging device to sway. The inability to ensure precise alignment between the culvert and the grating holes directly affects the normal operation of the dredging device. To solve this problem, existing technologies often require replacing the garbage pit grating with a thicker, reinforced one during the installation of the dredging device. Due to the complex and harsh environment in the garbage pit, the material requirements for the garbage pit grating are high, thus the thicker, reinforced garbage pit grating significantly increases construction and subsequent maintenance costs. In addition, early waste-to-energy plants typically did not consider lifting devices for equipment entering the drainage channel. Mechanical dredging equipment was mostly transported manually from the stairs to the drainage channel, which was difficult. The drainage channel is a limited space, and open flames and conventional electrical equipment cannot be used, which directly leads to the inability to use conventional lifting equipment. The equipment is installed entirely by hand, which is difficult to install, and subsequent maintenance also relies entirely on manual disassembly and transportation of equipment spare parts, making maintenance difficult.

[0003] The prior art disclosed in CN217996816U describes a device for clearing leachate from a landfill grating. This device is configured to clear gratings with elongated through-holes. The device includes a support frame, a pressure plate mounted on the support frame, and a drive mechanism for moving the pressure plate. The pressure plate is positioned corresponding to the grating and one end is hinged to the support frame. The pressure plate is connected to the drive mechanism, and under the control of the drive mechanism, it moves in a fan-shaped trajectory relative to the support frame around the hinge point. A clearing element is provided on the surface of the pressure plate corresponding to the grating, corresponding to the elongated through-holes on the grating. The clearing element acts on the elongated through-holes to clear them. Its structure is simple, the clearing method is singular and easily blocked by garbage, and it cannot handle clearing after the grating has shifted. Utility Model Content

[0004] In order to solve the problems existing in the existing garbage pit grating drainage system, this utility model provides a garbage pit leachate grating dredging device with superimposed dredging modules. It has a simple structure and is flexible in use. Its overall structure is tightly connected to the garbage pit grating, so even if the grating changes position during operation, it can always be dredged.

[0005] The present invention is achieved by the following technical solution: The present invention discloses a leachate grating plate dredging device with superimposed and combined dredging modules, including leachate grating plate dredging modules that are freely added or reduced in number according to actual needs and are set on the grating plate of the garbage pit. All leachate grating plate dredging modules are combined into one unit by spacing adjustment modules set on both sides, and the spacing of the leachate grating plate dredging modules is adjusted by the spacing adjustment modules to cope with different grating sizes.

[0006] The leachate grating unblocking module includes a rectangular frame structure unblocking support module. The inner side of the frame structure of the unblocking support module is equipped with a reciprocating linear pushing unblocking power element. The tail of the reciprocating linear pushing unblocking power element is movably connected to the unblocking support module, and the other end is connected to an unblocking execution module that can perform reciprocating motion on the grating grid. Each leachate grating unblocking module can unblock the grating independently or work together to unblock the grating.

[0007] All leachate grating unblocking modules are fixed to the grating plate by tie rod devices. When the grating plate changes position, all leachate grating unblocking modules remain relatively stationary with the grating plate by tie rod devices, ensuring that the unblocking support modules can always work without obstruction.

[0008] Furthermore, the dredging support module includes two parallel dredging supports. The front end of the dredging support is connected to a front guide plate, and the rear end is connected to a rear guide plate. The front end of the front guide plate is provided with two positioning pins for positioning the entire dredging support module on the grid plate. The rear end of the dredging support is provided with an ear seat a for connecting the reciprocating linear pushing dredging power element with pins.

[0009] Furthermore, the dredging execution module includes a frame whose size matches the space inside the dredging support module. At the front end of the frame, there are multiple through columns for dredging the grating plate that are fixed at equal intervals. At the middle of the rear end, there is an ear seat b for connecting with the end of the piston rod of the reciprocating linear pushing dredging power element. Two guide columns are provided parallel to each other on the upper and lower sides of the ear seat b. The tails of the two guide columns are matched with the guide holes opened on the rear guide plate to ensure the stability of the track when the dredging execution module reciprocates.

[0010] Furthermore, the tie rod device includes a tie rod seat connected to the tail end of the drainage support module of the leachate grating plate drainage module. Both the left and right ends of the tie rod seat are provided with tie rods between them and the grating plate, which generate a pulling force on the grating plate by the leachate grating plate drainage module. The position of the leachate grating plate drainage module is fixed by the tie rods.

[0011] Furthermore, the tie rod includes a telescopically adjustable threaded rod, which includes a threaded sleeve. The front and rear ends of the threaded sleeve are respectively connected to threaded rod II and threaded rod I via threads. Threaded rod I is connected to the tie rod seat, and threaded rod II is connected to a fastening device for fixing to the grating plate via pin II.

[0012] Furthermore, the fastening device includes a threaded shaft inserted into the grid of the grating plate. The threaded shaft is equipped with an anti-detachment plate and a nut that clamp the grating plate. The anti-detachment plate is fixed by a pin II. The structure of the anti-detachment plate and nut ensures that the anti-detachment plate will not loosen when it is impacted by an external garbage grab.

[0013] Furthermore, the leachate grating unblocking device can be arranged parallel to the ground or perpendicular to the ground. Beneficial effects

[0014] This device has a simple structure. Different numbers of leachate grating modules can be combined as needed. Multiple sets of leachate grating modules can work independently or be controlled by a program, which improves the flexibility of dredging control and reduces the dredging force that the leachate grating in the garbage pit needs to withstand.

[0015] The leachate grating unblocking device of this equipment is small in size and light in weight. At the same time, the unblocking support module of this equipment is not only the main support frame of the leachate grating unblocking device, but also the guiding component of the through column and guide column of the unblocking execution module. This greatly simplifies the overall structure and weight of the device. The through column and guide column of the leachate grating unblocking device pass through the front and rear guide plate holes of the unblocking support module and always remain in the holes without coming out. The front and rear guide plate holes determine the forward and backward direction of the through column. At the same time, the front and rear guide plates also bear the weight of the unblocking execution module, supporting the unblocking execution module and preventing it from falling down.

[0016] This device can be directly fastened to the leachate grating plate of the garbage pit and moves with the position of the grating plate, thus always adapting to the drainage holes on the grating plate. This ensures that the drainage holes can be cleared under normal circumstances no matter how the position of the grating plate changes. Moreover, the clearing force of a single leachate grating plate clearing device is small and will not damage the grating plate.

[0017] The through column of the leachate grating dredging device in this device is both a dredging execution component and a guide component. The through column passes through the hole in the front guide plate and always stays in the hole without coming out. The hole in the front guide plate determines the forward and backward direction of the through column, and at the same time, the hole in the front guide plate supports the through column and prevents it from falling down.

[0018] This device is small in size and light in weight, and can be adapted and combined according to different waste pool environments. It is easy to install and use in limited spaces, and can better adapt to waste pool structures under various environmental conditions, with good versatility. Attached Figure Description

Specific Implementation

[0031] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0032] like Figure 1 As shown, this utility model discloses a modular leachate grating dredging device for garbage pits. This device employs a modular design approach, decomposing the leachate grating dredging device into multiple independently functioning leachate grating dredging modules. These modules are then stacked and combined into a single unit using tie rods and spacing adjustment modules. When the size of the leachate grating in the garbage pit is small, only one set of leachate grating dredging modules can be used. Multiple leachate grating dredging modules respectively complete the dredging work of the leachate grating holes in the garbage pit, effectively reducing the strength requirements for leachate gratings with multiple sets of leachate grating dredging modules installed.

[0033] like Figure 1 , Figure 2 As shown, the present invention provides a leachate grating plate dredging device for garbage pits with superimposed and combined dredging modules. The device includes leachate grating plate dredging modules that are freely added or removed according to actual needs and are set on the garbage pit grating plate 8. All leachate grating plate dredging modules are combined into one unit through the spacing adjustment modules 5 set on both sides, and the spacing of the leachate grating plate dredging modules can be adjusted by the spacing adjustment modules 5 to accommodate different grating sizes.

[0034] The leachate grating unblocking module includes a rectangular frame structure unblocking support module 1. The inner side of the frame structure of the unblocking support module 1 is provided with a reciprocating linear pushing unblocking power element 3. The tail of the reciprocating linear pushing unblocking power element 3 is movably connected to the unblocking support module 1, and the other end is connected to an unblocking execution module 2 that can reciprocate against the grid of the grating plate 8. Each leachate grating unblocking module can unblock the grating plate 8 independently, or they can work together to unblock the grating plate 8.

[0035] All leachate grating unblocking modules are fixed to the grating plate 8 by tie rod devices. When the position of the grating plate 8 changes, all leachate grating unblocking modules always remain relatively stationary with the grating plate 8 by tie rod devices, ensuring that the unblocking support module 1 can always work without obstruction.

[0036] like Figure 3 , Figure 4 As shown, the unblocking support module includes an unblocking support 1-1, an ear seat a1-4, 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 located on the side of the unblocking support near the positioning pin 1-3, and the rear guide plate 1-5 is located on the side away from the positioning pin 1-3. Pull rod seats 7 are distributed on both sides of the unblocking support 1-1, and each pull rod seat 7 has a through hole for the pull rod to pass through. The unblocking support module 1 includes two parallel unblocking supports 1-1. The front end of the unblocking support 1-1 is connected to the front guide plate 1-2, and the rear end is connected to the rear guide plate 1-5. The front end of the front guide plate 1-2 is provided with two positioning pins 1-3 for positioning the entire unblocking support module 1 on the grid plate 8. The rear end of the unblocking support 1-1 is provided with an ear seat a1-4 for connecting the reciprocating linear pushing unblocking power element 3 with a pin.

[0037] like Figure 5 As shown, the unblocking execution module includes a frame, a through column, a guide column, and an ear seat; one end face of the frame has a set of through column mounting holes, and the corresponding end face has a guide column mounting hole and an ear seat; the through column is assembled in the through column mounting hole of the frame, and the guide column is assembled in the guide column mounting hole of the frame;

[0038] like Figure 2 As shown, the reciprocating linear pushing and unblocking power element is assembled on the lug of the unblocking support module at one end via a pin, and on the lug of the frame of the unblocking execution module at the other end.

[0039] like Figures 6-8 As 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. The threaded shaft 6-3 has a hole, and the pin shaft I 6-2 hinges the anti-detachment plate to the threaded shaft 6-3. The anti-detachment plate 6-1 can rotate around the pin shaft I 6-2.

[0040] like Figure 9 As shown, the spacing adjustment module includes a lead screw I 6-5 and a nut 6-4, which are used to adjust and fix multiple sets of leachate grating unblocking modules;

[0041] like Figure 1As shown, multiple sets of leachate grating unblocking modules are combined together by the spacing adjustment module 5. The positioning pin of the leachate grating unblocking module is inserted into the hole of the leachate grating. The threaded shaft 6-3 at one end of the pull rod is inserted into the hole of the grating. The anti-detachment plate 6-1 and the nut are distributed on both sides of the grating. One end is inserted into the hole of the pull rod seat 7 on the unblocking support module. The pull rod seat 7 is directly welded to the unblocking support module 1. The pull rod 6 fixes the multiple sets of leachate grating unblocking modules on the leachate grating.

[0042] like Figure 1 As shown, when the leachate grating device of the garbage pit is working, the reciprocating linear pushing and unblocking power element pushes the unblocking execution module 1 to move towards the grating plate 8, and the front end of the column passes through the hole of the grating plate. Then, the reciprocating linear pushing and unblocking power element pulls the unblocking execution module to move away from the grating plate 8, and the front end of the column exits from the hole of the grating plate, thus completing the unblocking work of the leachate grating plate hole.

[0043] When the leachate grating unblocking device for the garbage pit is in operation, each leachate grating unblocking module can independently complete the unblocking work of the leachate grating holes in the garbage pit, or the unblocking work of the grating holes can be completed by program control.

[0044] Preferred, such as Figure 10 As shown, the leachate grating plate unblocking device for the garbage pit can also be a single set of leachate grating plate unblocking modules and a tie rod 6 assembled on the leachate grating plate 8 to achieve unblocking of the grating plate holes.

[0045] Preferably, the reciprocating linear pushing and unblocking power element drives the unblocking execution module 2 to reciprocate linear motion, and the reciprocating linear pushing and unblocking power element 3 can be a variety of power components with reciprocating linear motion function, such as a cylinder, hydraulic cylinder or electric cylinder.

[0046] Preferably, the through columns 2-2 of the leachate grating unblocking device can be arranged in multiple rows and columns.

[0047] Preferably, the leachate grating unblocking device can be arranged parallel to the ground or perpendicular to the ground.

[0048] Preferred, such as Figure 11 As shown, when the grating plate will not change position due to external force, the leachate unblocking device can also be fixed to the grating plate and the garbage pool wall.
