Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of reservoir basin contaminated soil remediation, in particular to a kind of pumping storage power station reservoir basin processing flat rammer. BACKGROUND

[0002] Pumping storage power station reservoir basin refers to the key facility for storing water energy, usually composed of upper reservoir and lower reservoir, and realizes power grid peak shaving through pumping storage, and its core function is to store water in upper reservoir during power valley, and generate power during peak, to balance power grid load, and the reservoir basin must have high impermeability (such as using geomembrane or concrete face plate) to adapt to frequent water level changes, and in construction, part of the reservoir basin soil is contaminated, etc., which needs to be treated and controlled before subsequent construction, and the treatment of such soil needs to be plowed to the required depth, and then leveled by flat rammer after treatment.

[0003] The invention with publication number CN107574809A discloses an electric flat rammer, which can electrically drive the flat rammer body to realize ramming operation on the foundation, and the flat rammer body is not only compact in structure, but also convenient to operate, and a multifunctional control seat is arranged on the handrail assembly at the rear end of the flat rammer body, which can quickly complete the starting and steering of the flat rammer body, and the electronic imaging screen on the multifunctional control seat can reflect the picture taken by the monitoring probe device, and can real-time feedback the ramming work condition of the foundation during work.

[0004] The invention with publication number CN107503338A discloses a flat rammer, and the mounting seat is fixed on the ramming bottom plate, so that the ramming bottom plate is not pressed by the vibration box assembly, and has higher stability, and the flat rammer body is additionally provided with walking wheels for assisting walking, and the handrail rod has length adjusting function, which is suitable for different working requirements, and the ramming bottom plate of the flat rammer body is provided with two ends of the ramming bottom plate, which are set as roll-type plates, so that the ramming bottom plate will not produce ramming marks when ramming the ground.

[0005] However, the above-mentioned flat rammer for soil leveling has the following problems in actual use: the soil is leveled by the ramming plate driven by vibration, but such flat rammer has no corresponding rapid movement in different working environments, and cannot effectively realize transfer in the case of soil remediation plowing, and if the soil to be treated contains reagents, the ramming plate will be adhered to each other, which will cause clumping, corrosion, etc., and affect the flatness of the bottom of the ramming plate and the efficiency of subsequent ramming operation.

[0006] Therefore, we propose a kind of pumping storage power station reservoir basin processing flat rammer to solve the above-mentioned problems. SUMMARY

[0007] The purpose of this invention is to provide a plate compactor for the treatment of reservoir basins in pumped storage power stations. This invention addresses the problems of existing methods that use vibration to drive the compactor plate to level the soil. However, these plate compactors lack the ability to move quickly in different working environments and cannot be effectively moved when tilling the soil for treatment. Furthermore, some of the treated soil contains chemicals that can adhere to the compactor plate and, if not cleaned in time, easily cause clumping, corrosion, and other issues, affecting the flatness of the bottom of the compactor plate and the efficiency of subsequent compaction operations.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a pumped storage power station reservoir basin treatment plate compactor, comprising a compaction plate body for compaction operations after contaminated soil remediation, and a pusher bracket fixedly installed behind the top surface of the compaction plate body.

[0009] The tamping plate body has an eccentric wheel assembly at the front top end, an oil tank body above the eccentric wheel assembly, and a diesel engine unit at the rear top end of the tamping plate body, which is used to vibrate and compact the loosened soil.

[0010] The upper left and right sides of the tamping plate body are provided with support mechanisms to facilitate movement in the polluted loosened soil, and the support mechanism includes a set of moving wheels, which are rotatably installed at the bottom of the lifting support.

[0011] The bottom surface of the tamping plate body is provided with a decontamination mechanism, which includes a decontamination scraper, and the decontamination scraper scrapes away the residual soil containing the treatment agent.

[0012] Preferably, the support mechanism includes a support frame, which is fixedly installed on the front and rear sides of the top of the tamping plate body in a symmetrical manner. The upper end of the support frame is rotatably mounted with a lifting screw via a bearing, and the lower end of the lifting screw is rotatably mounted on the top surface of the tamping plate body via a bearing.

[0013] Preferably, the support mechanism includes a drive shaft, which is rotatably mounted on the front and rear sides of the top of the ramming plate body via bearings. The outer ends of the symmetrically distributed drive shafts are connected to the lower end of the lifting screw via bevel gears, and the upper end of the lifting screw is threadedly connected to the upper end of the lifting bracket.

[0014] Preferably, the support mechanism includes a limiting slide bar, the upper end of which is fixedly installed on the upper end of the support frame, and the lower end of which is slidably inserted through the interior of the lifting bracket. In the initial state, the lifting bracket drives the bottom moving wheel set to lift and support the ramming plate body.

[0015] Preferably, the decontamination mechanism includes a traction slide bar, which is located at the front end of the tamping plate body. The outer ends of the traction slide bars are all fixedly installed with traction brackets, and the outer ends of the traction brackets are fixedly installed on the outer wall of the tamping plate body. The traction slide bars are arranged in an inverted figure-eight shape.

[0016] Preferably, the cleaning mechanism includes a matching sleeve, which is disposed inside the front end of the cleaning scraper. The cleaning scraper is slidably fitted onto the outer wall of the traction slide rod through the internal matching sleeve, and the cleaning scraper slides against the bottom outer wall of the tamping plate body in a left-right symmetrical manner.

[0017] Preferably, the decontamination mechanism includes a traction steel cable, the front end of which is fixedly connected to the front end of the decontamination scraper, and the middle part of the traction steel cable passes through the traction bracket to form a guide. The rear end of the traction steel cable is wound and installed on the outer wall of the winding drum, while the winding drum is fixedly installed on the left and right sides of the front drive shaft.

[0018] Preferably, the decontamination mechanism includes a return spring, with the outer end of the return spring fixedly connected to the front end of the decontamination scraper and the inner end of the return spring fixedly connected to the middle of the front end of the tamping plate body. In the initial state, the decontamination scraper is distributed in the middle of the bottom surface of the tamping plate body and slides and rises along the traction slide bar during the compaction operation.

[0019] Preferably, the decontamination mechanism includes a traction slider, which is fixedly installed at the rear end of the decontamination scraper. A guide rod slides through the interior of the traction slider, and the guide rod is fixedly installed on the left and right sides above the rear end of the tamping plate body.

[0020] Preferably, the outer ends of the guide slide rod and the traction slide rod included in the decontamination mechanism are distributed in an inclined outward manner, so that the decontamination scraper moves to the left and right ends of the tamping plate body and then slides upward at an inclined angle, so that the decontamination scraper is positioned above the tamping plate body, thus avoiding affecting the tamping operation of the tamping plate body after the treatment of contaminated soil.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The pumped storage power station reservoir basin treatment plate compactor, through the support mechanism on the outside of the compactor plate body and the cooperation of the moving wheel set, can be transferred to different soil treatment areas. Before the compaction operation, the rising moving wheel set drives the decontamination scraper to move outward and rise, which helps to clean the attached soil and assists in compacting and leveling the soil after tillage and treatment. The specific details are as follows:

[0022] 1. The tamping plate body is moved between different working areas by symmetrically distributed moving wheel sets. The drive shaft on the top surface of the tamping plate body rotates, which drives the lifting screw connected to it to rotate through the bevel gear set. The lifting bracket, which is threaded to the lifting screw, is positioned by the limit slide rod, so that the lifting bracket drives the moving wheel set at the bottom to move upward, so that the tamping plate body can descend and contact the soil to be compacted for operation.

[0023] 2. The drive shaft drives the winding drum and winds up the traction cable, which in turn moves the cleaning scraper fixed at the front end. The moving cleaning scraper moves along the direction of the traction slide bar through the internal matching cylinder to clean the soil attached to the bottom surface of the cleaning scraper, thereby avoiding adhesion and affecting the compaction operation.

[0024] Furthermore, the inverted "V"-shaped traction rod drives the cleaning scraper to slide upwards, making the cleaning scraper higher than the height of the tamping plate body. This avoids affecting the contact between the tamping plate body and the soil during the compaction operation, while also scraping and cleaning the soil adhering to the bottom surface of the tamping plate body, improving the flatness of the compacted ground.

[0025] 3. The cleaning scraper is fitted onto the outer wall of the guide slide rod by a fixedly installed traction slider. The guide slide rod, which is inclined, limits the movement direction of the cleaning scraper and prevents it from obstructing the compaction operation of the tamping plate body.

[0026] Furthermore, the diesel engine unit above the tamping plate works, driving the eccentric wheel assembly to rotate through the pulley assembly, thereby transmitting vibration to the tamping plate body, and generating vertical vibration when in contact with the treated soil, thus assisting in compacting and leveling the tilled soil.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1-12 The present invention provides the following technical solution:

[0042] Example 1: To address the problems existing in the practical use of existing plate compactors, this example discloses the following technical solution: a plate compactor for reservoir basin treatment in a pumped storage power station, comprising a compaction plate body 1 for compaction operations after contaminated soil remediation. Support mechanisms are provided on both the upper left and right sides of the compaction plate body 1 to facilitate movement in the loosened contaminated soil. Each support mechanism includes a set of movable wheels 21, which are rotatably mounted on the bottom end of a lifting support 6. The support mechanism also includes a support frame 8, which is symmetrically fixed on the front and rear sides of the top of the compaction plate body 1. A lifting screw 9 is rotatably mounted on the upper end of the support frame 8 via a bearing, and the lower end of the lifting screw 9 is rotatably mounted on the top surface of the compaction plate body 1 via a bearing.

[0043] The support mechanism includes a drive shaft 10, which is rotatably mounted on the front and rear sides of the top of the tamping plate body 1 via bearings. The outer ends of the symmetrically distributed drive shafts 10 are connected to the lower end of the lifting screw 9 via a bevel gear set 11. The upper end of the lifting screw 9 is threaded through and connected to the upper end of the lifting bracket 6. The support mechanism includes a limiting slide rod 12, the upper end of which is fixedly mounted on the upper end of the support frame 8. The lower end of which is slidably disposed inside the lifting bracket 6. In the initial state, the lifting bracket 6 drives the bottom moving wheel set 21 to lift and support the tamping plate body 1.

[0044] like Figures 5-6 , Figures 11-12 As shown, the movable wheel sets 21 on the left and right sides of the tamping plate body 1 are supported by the lifting bracket 6, so that the movable wheel sets 21 are initially located below the tamping plate body 1, and can then be transferred to different soil treatment and tillage areas without the need for manual transport in complex terrain. When it is necessary to perform compaction work through the tamping plate body 1, the drive shafts 10 installed on the front and rear sides of the top of the tamping plate body 1 are driven to rotate by the servo motor, and the drive shafts 10 drive the outer bevel gear set 11 to rotate the meshing lifting screw 9. The lifting bracket 6, which is threadedly connected to the lifting screw 9, is limited by the limiting slide rod 12 under the support frame 8, so that the rotating lifting screw 9 drives the threaded lifting bracket 6 and the movable wheel sets 21 to slide upward. After the movable wheel sets 21 rise above the tamping plate body 1, the tamping plate body 1 contacts the treated soil for compaction work.

[0045] Example 2: In order to solve the problems existing in the actual use of the existing plate compactor, this example discloses the following technical solution: the bottom surface of the compactor plate body 1 is provided with a decontamination mechanism, and the decontamination mechanism includes a decontamination scraper 7, and the decontamination scraper 7 scrapes away the residual soil containing the treatment agent; the decontamination mechanism includes a traction slide bar 13, and the traction slide bar 13 is provided at the front end of the compactor plate body 1, and the outer end of the traction slide bar 13 is fixedly installed with a traction bracket 14, and the outer end of the traction bracket 14 is fixedly installed on the outer wall of the compactor plate body 1, and the traction slide bar 13 is distributed in an inverted "V" shape.

[0046] The cleaning mechanism includes a matching cylinder 15, which is located inside the front end of the cleaning scraper 7. The cleaning scraper 7 is slidably fitted onto the outer wall of the traction slide rod 13 through the matching cylinder 15 inside, and the cleaning scraper 7 slides against the bottom outer wall of the ramming plate body 1 in a left-right symmetrical manner.

[0047] The cleaning mechanism includes a traction cable 16, the front end of which is fixedly connected to the front end of the cleaning scraper 7, and the middle part of the traction cable 16 passes through the traction bracket 14 to form a guide. The rear end of the traction cable 16 is wound and installed on the outer wall of the winding drum 17, which is fixedly installed on the left and right sides of the front drive shaft 10. The cleaning mechanism includes a return spring 18, the outer end of which is fixedly connected to the front end of the cleaning scraper 7, and the inner end of which is fixedly connected to the middle of the front end of the tamping plate body 1. The cleaning scraper 7 in the initial state is distributed in the middle of the bottom surface of the tamping plate body 1 and slides and rises along the traction slide bar 13 during the compaction operation.

[0048] like Figures 9-10 As shown, the drive shaft 10 above the tamping plate body 1 drives the winding drum 17 when it rotates. After the winding drum 17 winds up the traction steel cable 16 wound around the outer wall, the middle of the traction steel cable 16 drives the traction bracket 14, which in turn drives the cleaning scraper 7 fixedly connected to the front end to slide outward. During the movement, the cleaning scraper 7 is always in contact with the bottom surface of the tamping plate body 1. After moving to the outer end of the tamping plate body 1, the traction slide rod 13 drives the cleaning scraper 7 to continue to slide upward through the inverted "V" shape, so that the cleaning scraper 7 is higher than the height of the tamping plate body 1. This avoids affecting the contact between the tamping plate body 1 and the soil during the compaction operation, while also scraping and cleaning the soil attached to the bottom surface of the tamping plate body 1, thus improving the flatness of the compacted ground.

[0049] The decontamination mechanism includes a traction slider 19, which is fixedly installed at the rear end of the decontamination scraper 7. A guide slide rod 20 slides through the interior of the traction slider 19 and is fixedly installed on the left and right sides above the rear end of the tamping plate body 1. The guide slide rod 20 and the outer ends of the traction slide rod 13 in the decontamination mechanism are both distributed in an inclined outward manner, so that after the decontamination scraper 7 moves to the left and right ends of the tamping plate body 1, it slides upward at an inclined manner, so that the decontamination scraper 7 is positioned above the tamping plate body 1, thus avoiding affecting the compaction operation of the tamping plate body 1 after the treatment of contaminated soil.

[0050] A pusher bracket 2 is fixedly installed at the rear of the top surface of the tamping plate body 1; an eccentric wheel group 3 is provided at the front end of the top surface of the tamping plate body 1, and an oil tank body 4 is installed above the eccentric wheel group 3; and a diesel engine 5 is provided at the rear end of the top surface of the tamping plate body 1 for vibrating and compacting the loosened soil.

[0051] like Figures 7-8 As shown, during the sliding process, the rear ends of the cleaning scrapers 7 on the left and right sides of the bottom surface of the tamping plate body 1 are sleeved onto the outer wall of the guide slide rod 20 through the fixedly installed traction slider 19. Thus, the guide slide rod 20, which is inclined, limits the movement direction of the cleaning scraper 7, preventing it from obstructing the tamping operation of the tamping plate body 1.

[0052] like Figures 3-4 As shown, during operation, the diesel engine unit 5 above the tamping plate body 1 is connected to the eccentric wheel assembly 3 through the side pulley assembly. This causes the eccentric wheel assembly 3 to rotate in a different direction due to the eccentric blocks on the outer wall of the rotating shaft, thereby transmitting vibration to the tamping plate body 1. When it comes into contact with the treated soil, it generates vertical vibration, which in turn helps to compact and level the treated soil.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
