Description

Technical Field

[0001] This invention belongs to the field of photovoltaic civil engineering construction machinery technology, specifically relating to a material level monitoring, anti-slip, and anti-tilting mountain photovoltaic pile pouring trolley system and method. Background Technology

[0002] Mountain photovoltaic power stations are mostly located on steep slopes and in muddy mountainous areas. Micro-hole cast-in-place piles are the mainstream foundation form for photovoltaic supports. The pile points are scattered and the terrain is highly undulating, and the existing pouring and transportation equipment has multiple shortcomings. The current mainstream construction methods are tracked machinery, heavy-duty drones, or simple hand-pushed hoppers: tracked equipment crushes and damages native turf, resulting in high ecological restoration costs; drones have extremely low single-batch payloads and cannot operate in windy weather, resulting in poor overall construction efficiency; traditional wheeled hoppers lack anti-slip structures, making them prone to slipping and tipping over on rainy, snowy, and muddy slopes. At the same time, traditional equipment lacks material level monitoring structures, making it easy to spill and waste material when pouring concrete; hopper transfer relies on manual pushing, requiring a large manpower input for large-area sites; material discharge relies on manually inserting and removing gate valves, making it impossible to judge the grouting fullness in real time, which can easily lead to pile breakage, over-grouting, and other quality defects, and there is no anti-tipping protection, posing a risk of overturning when traveling on steep slopes. Existing single-function improvement devices only address a single pain point such as anti-slip and automatic material discharge, and cannot simultaneously meet the multiple needs of mountain construction, including ecological protection, automatic transfer, material level control, anti-slip and anti-tipping, and intelligent valve closing. As a result, the overall construction is not intelligent or reliable enough. Summary of the Invention

[0003] The purpose of this invention is to provide a material level monitoring, anti-slip, and anti-tilting mountain photovoltaic pile pouring trolley system and method to solve the technical defects of existing mountain photovoltaic pouring equipment, such as crushing and damaging turf, slipping and overturning on muddy slopes due to rain and snow, lack of material level monitoring structure which easily leads to concrete overflow, reliance on manual pushing for transportation which requires a large amount of manpower, reliance on manual valve control for grouting which easily leads to pile breakage and over-grouting quality defects, inability to simultaneously adapt to multiple construction conditions in mountainous areas, and insufficient intelligence and operational reliability of the device.

[0004] To achieve the above objectives, this application provides the following technical solution: The first aspect of this application provides a material level monitoring, anti-slip, and anti-tilting mountain photovoltaic pile pouring trolley system, comprising: A wheeled chassis equipped with anti-skid tires and an anti-rollover mechanism, wherein the anti-skid tires have a puncture structure fixed inside; A hopper is located on the upper part of the wheeled walking chassis. The bottom end of the hopper is connected to a discharge pipe. An electronic discharge valve and a grouting detection sensor are provided at the discharge pipe. A traction unit, in conjunction with a wheeled chassis, is equipped with a push drive device, which is used to push the wheeled chassis toward the working slope. The control component is communicatively connected to the material level sensor, the push drive device, the electronic discharge valve, and the grouting detection sensor; while receiving the signal from the material level sensor to control the start and stop of the push drive device, the control component also receives the signal from the grouting detection sensor to control the closing of the electronic discharge valve.

[0005] In one optional embodiment, the level sensing module includes: Contact level probe; The contact-type material level probe is fixedly installed at the preset highest material level position on the inner wall of the hopper; The signal output terminal of the contact level probe is remotely connected to the control component.

[0006] In one optional embodiment, the anti-slip puncture assembly includes: Multiple telescopic spikes are evenly distributed along the circumference of the anti-skid tire; The telescopic ends of the telescopic serrations face the soil contact surface on the outer side of the tire.

[0007] In one optional embodiment, the anti-rollover assembly includes: Two sets of telescopic support arms, which are symmetrically hinged to the left and right sides of the wheeled chassis; The bottom end of the telescopic support arm can abut against the slope to achieve side roll-off limitation.

[0008] In one optional embodiment, the push-driven device includes: An electric push rod, the output end of which can abut against the front end of a wheeled chassis; The electric actuator is remotely connected to the control components.

[0009] In one optional embodiment, the electronic discharge valve is installed in the middle section of the discharge pipe; The grouting detection sensor is fixedly installed at the outlet of the discharge pipe.

[0010] In one alternative embodiment, the traction unit includes: The traction device includes a traction wire rope and a traction lug, with the push drive device built into the traction device. The traction lug is fixedly mounted on the front end of the wheeled chassis; One end of the traction wire rope is detachably fastened to the traction lug, and the other end is connected to the traction equipment.

[0011] In an optional embodiment, it further includes: A locking and fixing assembly, the locking and fixing assembly including a detachable locking bracket; The detachable locking bracket is located between the bottom of the hopper and the wheeled chassis. The two ends of the detachable locking bracket are respectively bolted to the outer wall of the hopper and the wheeled chassis.

[0012] In one alternative embodiment, the control component includes: The signal processing module, built into the control component, can output control signals to the push drive device and the electronic discharge valve respectively.

[0013] A second aspect of this application provides a method for pouring anti-slip and anti-tilting photovoltaic piles in mountainous areas using a material level monitoring system. The method employs the aforementioned material level monitoring anti-slip and anti-tilting photovoltaic pile pouring trolley system, comprising: The concrete pouring hopper system is placed on the slope platform. The traction wire rope of the traction unit is connected to the traction lug at the front of the wheeled chassis, and the external conveying equipment is started to pour concrete into the hopper. The contact level probe on the inner wall of the hopper collects the level signal in real time and transmits it to the control component. When the level reaches the preset height, the control component controls the electric push rod of the push drive device to extend, pushing the wheeled chassis to the top of the slope and then stopping the push. Release the electric push rod to move the tractor unit along the slope by pulling the dump truck with a steel wire rope. The telescopic serrations inside the anti-skid tires extend and penetrate the mud / ice to prevent slipping. During the movement on the slope, the telescopic support arms on both sides land to achieve anti-tipping and limit. The dump truck arrives at the grouting point of the photovoltaic pile, and the manual connection between the discharge pipe and the grouting port of the pile is made. The control component opens the electronic discharge valve to pour concrete. The grouting detection sensor collects the grouting completion signal in real time and feeds it back to the control component. After receiving the signal, the control component closes the electronic discharge valve, and the single pouring operation is completed.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The wheeled chassis avoids large-scale damage to the turf in the work area, and the anti-skid tires with puncture structure ensure the reliability of the wheeled chassis movement in rainy and snowy weather. Secondly, the anti-tipping mechanism allows the wheeled chassis to move stably in the work slope area, and the hopper with discharge monitoring and control structure and the integrated push-drive traction unit can solve the technical defects of concrete overflow, low efficiency of manual pushing, and easy breakage and over-pouring of piles by manual valve control.

[0015] 2. The contact-type material level probe is fixedly installed at the highest material level position of the hopper. The probe communicates remotely with the control components. It uses the fixed-point deployment of contact-type sensing structure to capture the upper limit of concrete material level, which solves the defects of traditional hoppers that have no material level monitoring and cannot predict the total amount of filler, and the waste of material due to excessive concrete filling. The sensing signal can be remotely and stably transmitted to the control system, ensuring the reliability of the linkage shutdown logic after the material is full. It eliminates the operation mode of manual on-site material monitoring, reduces the workload of manual control, and stabilizes the filling accuracy.

[0016] 3. Multiple telescopic serrations are evenly distributed along the circumference of the tire, with the ends of the serrations facing the tire's contact patch. The extendable serrations penetrate into the wet, soft soil or icy surface of the mountain, increasing the tire's grip and friction. This solves the problems of muddy and icy roads in rainy and snowy weather, easy slippage of conventional wheeled tires, and obstructed vehicle movement. Furthermore, the evenly distributed serrations ensure balanced circumferential grip of the tire, stable power transmission during movement, and improve the smoothness of the dump truck's movement on complex mountain slopes and its adaptability to all-weather operations.

[0017] 4. Two sets of symmetrically hinged telescopic support arms are adopted on both sides of the chassis. The bottom of the support arms can abut against the slope limit. Relying on the double-sided telescopic support structure, the vehicle can land and support itself when traveling on the slope, which makes up for the defect of traditional dump trucks that are prone to tipping over on steep slopes due to the lack of protective structure. The telescopic structure can be flexibly extended and retracted to adapt to different slope terrains, without interfering with the transfer on flat ground. It takes into account the safety of steep slope operation and the convenience of flat ground passage, and eliminates the safety hazard of vehicle tipping over on mountain slopes.

[0018] 5. An electric push rod is selected as the pushing drive component. The push rod pushes the front end of the chassis and communicates remotely with the control components. The electric push rod enables automated pushing of the bucket truck onto the working slope, replacing the original manual pushing method. This solves the problems of high manpower consumption and low overall construction efficiency in large-area photovoltaic fields. The push rod's movement is uniformly controlled by the system, with precise and controllable starting and stopping timing, stable pushing force, reduced human error, and improved automation of slope transportation.

[0019] 6. The electronic discharge valve is placed in the middle section of the discharge pipe, and the grouting detection sensor is fixed at the discharge pipe opening. The sensor at the pipe opening collects the grouting completion status in real time. In conjunction with the middle section electric control valve, the discharge is automatically turned on and off. This solves the problem that manual valve opening and closing cannot accurately judge the grouting fullness, which can easily lead to quality defects such as over-pouring of concrete and under-pouring, resulting in broken piles. The sensor point is close to the grouting interface, and the detection response is timely, ensuring that the grouting fullness meets the standard and stabilizing the quality of pile foundation formation.

[0020] 7. The traction unit consists of traction equipment, wire rope, and chassis traction lugs. The wire rope can be detachably connected to the lugs, and the detachable traction structure facilitates quick assembly and disassembly on the construction site. It is suitable for frequent site changes in mountainous areas, solving the efficiency problems of cumbersome traction connection and disassembly and the long preparation time for pile replacement operations in mountainous areas. The push drive is integrated inside the traction equipment, resulting in higher equipment integration, simpler layout of scattered points in mountainous areas, and neater pipeline arrangement, reducing the equipment collision failure rate in complex mountainous environments.

[0021] 8. A detachable locking bracket is used to connect the hopper and the chassis. The bracket is fixed at both ends by bolts. The detachable assembly structure with bolts allows for quick assembly and disassembly of the hopper, which is convenient for cleaning, maintenance and transportation of the hopper. This solves the problems of integrated hoppers being difficult to maintain and time-consuming repair of equipment failures in mountainous areas. The locking structure is firmly connected and the hopper will not shift or loosen under the vibration of the pouring process, ensuring stable concrete delivery. At the same time, it is convenient to transport the equipment in parts uphill, which is suitable for mountainous road transportation conditions.

[0022] 9. A signal processing module is set up inside the control component. The signal processing module outputs control signals to the push drive and the discharge valve respectively. The walking push and grouting discharge actions are controlled separately by using signal channels to solve the problem of control confusion and miscoordination of push and valve closing actions caused by multiple mixed signals.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Currently, most domestic mountain photovoltaic power station sites are concentrated in hilly and mountainous areas, with construction areas spread across a wide range of slopes. The photovoltaic pile foundations are scattered throughout the site, and the terrain is highly undulating, making conventional concrete transport and pouring equipment ill-suited to the complex mountainous conditions. Traditional construction methods generally use tracked construction machinery, heavy-duty transport drones, or simple hand-push concrete hoppers for concrete transport and pouring, all of which have significant shortcomings. Tracked equipment is heavy, and its movement crushes and tears the native grass, causing severe damage to the mountain ecosystem. Subsequent ecological restoration requires substantial investment and time. Heavy-duty drones have limited single-load concrete capacity, resulting in low overall transport efficiency. They cannot operate in strong winds or rainy weather, making them highly unsuitable for various environments. Conventional wheeled hand-push hoppers lack anti-slip structures. In rainy or snowy weather, the working slopes become muddy and icy, reducing tire grip and causing wheel spin and vehicle slippage, severely delaying the pouring schedule. Meanwhile, traditional hoppers lack professional material level monitoring hardware. When external conveying equipment continuously adds concrete to the hopper, it is impossible to accurately control the upper limit of the filler. Concrete often overflows from the top of the hopper, not only wasting concrete raw materials but also causing spilled concrete clumps to contaminate the working slope and increase on-site cleanup workload. Traditional equipment relies entirely on manual pushing for hopper transfer. Mountainous photovoltaic construction sites cover a wide area with a large number of piles. Relying on manual pushing of the bucket truck back and forth between the platform and the slope results in a large labor input and low overall work efficiency. Traditional discharge structures rely on manual insertion and removal of valves to control concrete discharge. Construction personnel cannot visually judge the degree of concrete filling inside the photovoltaic piles, which easily leads to insufficient concrete filling causing pile breakage defects or excessive filling causing waste. Conventional slope transfer bucket trucks lack anti-tipping protection structures. When the bucket truck is traveling on an inclined working slope, the center of gravity shifts, which is prone to side-tipping accidents.

[0029] Most of the existing improved equipment on the market only optimizes a single function such as anti-slip and automatic material discharge, and cannot simultaneously meet the multiple construction needs of ecological protection, precise material level control, automated transfer, slope anti-slip, vehicle anti-tipping, and intelligent valve shut-off for grouting. The overall intelligence level of the equipment is insufficient, and the stability of all-weather mountain construction is poor.

[0030] To address the technical deficiencies mentioned in the background section, this embodiment provides a material level monitoring, anti-slip, and anti-tilting mountain photovoltaic pile casting trolley system and method.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings: like Figures 1-2 As shown, in a first aspect of the present invention, a material level monitoring, anti-slip, and anti-tipping mountain photovoltaic pile pouring trolley system is provided, comprising: a wheeled chassis equipped with anti-slip tires and an anti-tipping mechanism, wherein the anti-slip tires have a puncture structure fixed inside; a hopper 1, located on the upper part of the wheeled chassis, the bottom end of the hopper 1 being connected to a discharge pipe, the end of the discharge pipe being provided with a discharge port 2, and a discharge volume control device 3 being provided at the discharge pipe, the discharge volume control device 3 including an electronic discharge valve and a grouting detection sensor; a traction unit 10, which cooperates with the wheeled chassis for traction, the traction unit 10 including a first traction device 8 and a second traction device 9, and a push drive device using a DC motor drive device 4 is provided in the traction unit, the push drive device being used to push the wheeled chassis towards the working slope 11; and a control component equipped with a wireless receiving control device 7, which is communicatively connected to the material level sensor, the push drive device, the electronic discharge valve, and the grouting detection sensor; the control component receives signals from the material level sensor to control the start and stop of the push drive device, and simultaneously receives signals from the grouting detection sensor to control the closing of the electronic discharge valve.

[0032] In this embodiment, the wheeled chassis adopts a widened four-wheel layout, and the walking wheels are made of solid rubber wide tires to form anti-skid tires. The widened structure can increase the contact area between the tires and the ground, reduce the pressure of the wheels on the ground, and the wheeled walking mode is different from tracked machinery. The degree of compression and tearing of the grass and turf of the mountain during the walking process is greatly reduced, effectively reducing the damage to native vegetation and reducing the cost of mountain ecological restoration.

[0033] The anti-skid tires are internally fitted with a puncture structure, which increases traction when the vehicle is traveling on muddy or icy slopes. The wheeled chassis is equipped with a steering device 5 at the front, which controls the deflection angle of the front wheels, enabling the dump truck to turn flexibly on flat ground and slopes. This adapts to the turning and U-turn needs of narrow working surfaces and densely packed pile areas in mountainous terrain, solving the problems of difficult turning and limited movement routes for dump trucks in confined mountain spaces.

[0034] The left and right sides of the wheeled chassis are equipped with anti-rollover mechanisms. The anti-rollover mechanisms can provide lateral support and limit the vehicle during driving on slopes, thus avoiding the risk of the vehicle overturning. A hopper 1 is fixedly installed on the top of the wheeled chassis. The hopper 1 is used for temporary storage and transportation of concrete. A material discharge channel is opened at the bottom of the hopper 1 and connected to the discharge pipe. The end of the discharge pipe is processed into a discharge port 2. The discharge volume control device 3 is installed in the middle section of the discharge pipe and at the pipe opening.

[0035] In this embodiment, the traction unit includes a first traction device 8, a second traction device 9, and a traction unit 10. The first traction device 8 is mounted on the wheeled chassis, and the second traction device 9 is mounted on the traction unit body. The first traction device 8 and the second traction device 9 cooperate to realize the traction operation of the wheeled chassis. A push drive device is installed inside the traction unit body. The push drive device relies on the DC motor drive device 4 to provide power input. The function of the push drive device is to provide horizontal thrust to the wheeled chassis and push the whole vehicle from the flat platform to the top of the working slope 11.

[0036] In this embodiment, the control component is a built-in wireless receiving and control device 7, which is used to realize long-distance signal transmission and reception. The control component is connected to the material level sensor, the push drive device, the steering device 5, the electronic discharge valve inside the discharge quantity control device 3, and the grouting detection sensor through wired and wireless communication modes, respectively.

[0037] The control component can realize multiple independent control logics. The first logic uses the material height signal inside the hopper 1 collected by the material level sensor to control the start and stop of the push drive device. The second logic uses the grouting completion signal collected by the grouting detection sensor to control the on and off of the electronic discharge valve. The third logic remotely controls the steering action of the front wheel of the steering device 5, realizing the automated linkage control of the entire process of filling, transfer, steering and grouting, minimizing manual operation intervention, and adapting to large-scale pile foundation construction of photovoltaic systems in mountainous areas.

[0038] All components in this system adopt a modular assembly design, allowing for disassembly and transportation between components, making it suitable for transportation conditions on narrow mountain roads. All electrical control components support remote wireless communication, enabling operators to control the equipment from a safe area without having to follow the dump truck up and down dangerous slopes, further improving the safety of mountain construction.

[0039] Furthermore, the wheeled chassis is made of welded steel frame, which is strong enough to support the weight of a fully loaded concrete hopper. It can also withstand the alternating tensile and thrust forces brought about by walking on slopes and pushing and traction. The steel frame has strong resistance to deformation and is not prone to deformation and cracking under long-term mountain bumpy conditions.

[0040] Four sets of anti-skid tires are installed at the bottom of the chassis, with the four wheels arranged symmetrically. The front wheels are fixedly mounted to the steering device 5, and the rear wheels are follow-up load-bearing wheels to ensure even force distribution when driving on flat ground and slopes. The steering device 5 includes steering linkages, steering shafts, and electric steering actuators. The steering shaft is mounted laterally at the front of the chassis, with both ends of the shaft connected to the two front wheels. Multiple sets of steering linkages are hinged to the shaft and wheel frame. The electric steering actuator is fixed at the front crossbeam of the chassis. The electric steering actuator's wiring is connected to the control components and the wireless receiving control device 7, which can remotely control the motor to rotate forward and backward, driving the shaft and linkages to complete the left and right deflection of the front wheels, thus achieving vehicle steering.

[0041] When the terrain is narrow and the pile positions are densely packed, the operator can remotely control the steering device 5 to adjust the front wheel angle, flexibly completing small-radius turns and U-turns. This adapts to the repositioning of vehicles in densely packed photovoltaic pile locations, avoiding the drawbacks of traditional non-steering dump trucks that can only tow in a straight line and cannot flexibly adjust their orientation. During turning on wet and slippery slopes in rain or snow, the steering device 5 can precisely control the front wheel angle, preventing excessive steering angle from causing the vehicle to fishtail and skid.

[0042] The anti-skid tires are made of thickened solid rubber, which is wear-resistant and cut-resistant. Mountain gravel and hard soil will not easily cut the tire tread, extending the tire's outdoor lifespan. The tire body has a fixed puncture structure, which corresponds to a matching anti-skid puncture component. This component consists of multiple telescopic puncture teeth, all evenly arranged around the inner wall of the tire body, with the telescopic ends facing the outer soil contact surface.

[0043] When transporting goods on flat ground, the telescopic spikes retract and are stored inside the tires, so the spikes do not touch the ground and will not scratch the turf. When the slope is muddy or icy in rainy or snowy weather, the telescopic spikes extend outward in a controlled manner, and the tips of the spikes penetrate into the mud or ice on the slope. The mechanical interlocking action of the spikes greatly improves the tire's grip, prevents the wheels from spinning and slipping, and ensures that the truck can travel stably on wet and slippery slopes.

[0044] The evenly distributed serrations ensure that the tire has serrations that can engage with the ground at any position on the entire circumference, providing grip without any blind spots and preventing the problem of insufficient grip on one side and deviation.

[0045] The wheeled chassis is symmetrically equipped with anti-rollover mechanisms on both sides, and corresponding anti-rollover components. These components include two sets of telescopic support arms, which are hinged to the left and right side beams of the chassis. The hinged structure ensures the support arms can be retracted upwards or downwards without any jamming. During transport on flat ground, the telescopic support arms retract upwards to fit against the sides of the chassis, without occupying additional lateral space or affecting normal movement. When the truck enters the sloping surface of the working slope 11, the overall center of gravity of the equipment shifts downhill. At this time, the telescopic support arms rotate downwards and extend, with the bottom of the arms directly contacting the slope surface, forming a rigid lateral support limit.

[0046] Even if the vehicle's center of gravity shifts due to bumpy terrain, the side support arms limit the maximum tilt angle of the chassis, preventing the vehicle from tipping over and eliminating the safety hazard of overturning on steep slopes. The telescopic support arms can be flexibly adjusted according to the actual slope of the working slope 11; the steeper the slope, the longer the support arms extend, adapting to different mountain slope conditions and offering greater versatility. The chassis has a wider overall wheelbase, coupled with dual side support arms and a controllable steering device 5, ensuring both stability and steering flexibility, balancing maneuverability on flat ground with safety on slopes.

[0047] The wheeled chassis is made of standardized steel components, and all welding points are treated with anti-rust spraying. It will not rust quickly when exposed to rain and soil erosion in mountainous outdoor areas, and the equipment's weather resistance is suitable for long-term field construction. The front of the chassis is welded with a traction lug, which is a thickened lifting ring structure that can withstand traction force and is not easily torn. The traction lug serves as the connection point between the chassis and the traction unit, facilitating quick disassembly and assembly of the traction wire rope. The battery 6 is fixedly installed in the empty frame space of the chassis. The battery 6 provides unified power to the steering device 5, various sensors, drive structure, and valves.

[0048] Hopper 1 is constructed from bent and welded steel plates, featuring a hopper-shaped structure that is wider at the top and narrower at the bottom. The large top opening facilitates concrete reception, while the tapered bottom allows for concentrated downward discharge. The inner wall of the hopper is polished to prevent concrete from adhering to the walls, ensuring smooth discharge and preventing blockages. Hopper 1 has a total height of 1600mm; the upper straight cylinder is 700mm high, the lower conical cylinder is 900mm high, and the top opening is 1800mm. 1800mm, bottom discharge port 350 350mm.

[0049] The hopper 1 is mounted on the upper part of the wheeled chassis. The hopper 1 and the chassis are connected by a locking and fixing assembly, which is a detachable locking bracket. This bracket is positioned between the bottom outer wall of the hopper 1 and the upper surface of the wheeled chassis. Both ends of the bracket are secured to the outer wall of the hopper 1 and the top surface of the chassis with high-strength bolts. All connection points are evenly tightened with multiple sets of bolts, ensuring sufficient bolt tightening force. During concrete discharge vibrations and vehicle bumps on slopes, the hopper 1 will not shake or shift relative to the chassis, ensuring the stability of the discharge pipe position. The detachable locking bracket is a split structure, allowing operators to unscrew all the bolts and remove the hopper 1 entirely from the chassis. Disassembling the hopper 1 separately facilitates manual access to clean clumps of concrete, simplifying equipment inspection and maintenance. In mountainous areas, the hopper 1 and chassis can be transported separately, reducing the overall size of the equipment and making it suitable for transport on narrow rural roads.

[0050] A material level sensing module is fixedly installed on the inner wall of hopper 1. The material level sensing module is a contact material level probe. The contact material level probe is precisely fixed at the highest material level height position preset on the inner wall of hopper 1. This height is the maximum upper limit height that concrete can be contained.

[0051] When the external conveying equipment pumps concrete into hopper 1, the concrete level rises continuously. When the concrete level touches the contact level probe, the probe immediately triggers a material arrival signal. The contact level probe is equipped with a dedicated signal cable, which serves as the signal output terminal and establishes a remote communication connection with the control component. The level signal collected by the probe is transmitted to the control component in real time, realizing remote real-time monitoring of the level.

[0052] By using contact probes arranged at fixed points, the upper limit of the filling material is precisely controlled, preventing excessive concrete from overflowing from the top of hopper 1, reducing concrete waste. There is no need for continuous manual monitoring of the filling height of hopper 1, reducing the workload of manual operation. The material level sensing module adopts a contact mechanical triggering structure, which is different from ultrasonic and radar sensors. Mountain dust and concrete water mist will not interfere with the detection accuracy, and the detection stability is higher in complex outdoor working conditions.

[0053] The lowest end of hopper 1 is welded to a rigid discharge pipe, which extends downwards along the side of the chassis. The discharge pipe opens at its very end to form discharge port 2, which is a standard circular opening for easy connection to various photovoltaic pile grouting hoses. The discharge pipe has a two-section control structure. An electronic discharge valve is installed in the middle section of the discharge pipe, and a grouting detection sensor is fixedly installed at discharge port 2. The electronic discharge valve and the grouting detection sensor are both part of the discharge volume control device 3.

[0054] The electronic discharge valve adopts an electric gate valve structure. The gate valve is sealed and fastened to the middle section of the discharge pipe by a flange. The flange gasket ensures that there is no concrete leakage at the pipeline connection. The on / off action of the electric gate valve is controlled by an electrical control signal, replacing the traditional manual valve opening and closing. The grouting detection sensor is arranged close to the discharge port 2. The sensor can detect the concrete filling status inside the grouting pipeline in real time and accurately determine when the concrete inside the photovoltaic pile is full. All discharge control hardware is integrated into the discharge pipeline. The pipeline layout is compact and will not interfere with the chassis walking structure or steering device 5. The pipeline will not be damaged by bumping or turning on slopes.

[0055] The traction equipment is a ground-mounted traction unit that can be placed on a flat platform at the top of the working slope 11. The unit's self-weight is sufficient to prevent displacement during traction operations due to the tension of the steel wire rope. The winding end of the traction equipment connects to the traction unit 10, which is a steel wire rope. This steel wire rope possesses wear-resistant and tensile strength properties, making it resistant to breakage from friction against sharp rocks in mountainous terrain. The end of the steel wire rope can be quickly snapped onto the traction lug at the front of the wheeled chassis. The snap is a detachable quick-release structure, allowing for easy assembly and disassembly. Construction personnel can connect and disconnect the steel wire rope and lug with one hand. This allows for rapid assembly and disassembly to switch traction points during frequent relocation operations in mountainous terrain, improving relocation efficiency. The other end of the traction steel wire rope is stored inside the drum of the traction equipment. The traction equipment can rotate the drum in both forward and reverse directions to wind up and unwind the steel wire rope. The steel wire rope pulls the wheeled chassis up and down the working slope 11. During transport, the steering device 5 can be used to fine-tune the vehicle's orientation to avoid scraping against protruding rocks on the slope, enabling long-distance transport on the slope.

[0056] The traction equipment has an embedded push drive device inside its body. The power source of the push drive device is a DC motor drive device 4. The DC motor drive device 4 provides stable DC power to the electric actuator, which is suitable for mountain construction scenarios in the field where there is no external mains power. The DC power supply can rely on the chassis battery 6 for continuous power supply, and the range can meet the needs of a full day of pouring operations.

[0057] The actuator of the push drive device is an electric push rod. The electric push rod is horizontally arranged on the side of the traction equipment facing the slope platform. The extension rod output end of the electric push rod faces the front vertical surface of the wheeled chassis. When the push rod is extended, it can horizontally push against the chassis, providing the whole vehicle with a horizontal thrust towards the working slope 11.

[0058] The control circuit of the electric push rod is connected to the wireless receiving control device 7. The electric push rod and the control component are remotely connected. The control component can send signals to control the extension and retraction of the electric push rod. The entire pushing logic is linked with the material level signal. After the hopper 1 is filled to the standard, the control component automatically controls the electric push rod to extend and push the wheeled chassis from the flat platform to the working slope 11. The walking route can be finely adjusted with the steering device 5 during the pushing process. When the chassis is pushed to the top of the working slope 11, the push rod receives the position feedback signal and automatically retracts to stop the pushing force, and the pushing action ends. This completely replaces the original manual pushing mode of workers. It reduces a lot of manpower consumption in large-scale mountain construction. The timing of the push start and stop is precisely controlled by the electric control, and there are no problems of uneven pushing force or inaccurate pushing distance control by manual pushing.

[0059] The push drive device is concealed inside the traction equipment, preventing it from being exposed to the elements and reducing erosion from sun and rain. This also results in a lower hardware failure rate. The device enables a two-stage transport mode: electric push of the platform and steel wire rope traction on slopes. For short-distance platform pushes, the steering device 5 allows for flexible alignment, while long-distance steel wire rope traction on slopes provides stability and safety. It is suitable for segmented travel paths on mountain platforms and slopes.

[0060] In this embodiment, the control component housing has an outdoor waterproof and dustproof protection level, making it suitable for mountainous rainy days and dusty construction environments. All electrical control components inside the housing are shockproof and fixed, so vehicle bumps will not cause the wiring to come loose. The control component housing is equipped with a wireless receiving and control device 7, which supports long-distance wireless signal transmission and reception. Operators can use a handheld remote control to issue various control commands in a safe area without having to approach the inclined slope to operate the equipment, thus avoiding the risk of falling objects and soil slippage that could injure people.

[0061] The control component integrates a signal processing module, which is divided into three independent signal output channels. The first channel is dedicated to the push drive device, the second channel is dedicated to the electronic discharge valve of the discharge quantity control device 3, and the third channel is dedicated to the steering device 5. The three signals are transmitted independently and there will be no signal crosstalk.

[0062] The signal input terminals of the signal processing module are connected to the material level sensor and the grouting detection sensor respectively to realize the synchronous acquisition of two detection signals; the first control logic: when the concrete inside the hopper 1 rises to the limit height, the contact material level probe transmits an electrical signal to the signal processing module. After processing, the module sends a start signal to the push drive device. The DC motor drive device 4 drives the electric push rod to extend the trolley; after the chassis reaches the top of the slope, the position feedback signal is sent to the module, the module stops outputting, the push rod retracts, and the pushing action ends.

[0063] The second control logic: During the grouting operation, concrete is poured into the photovoltaic pile foundation through the discharge port 2 of the discharge pipe. The grouting detection sensor collects the pipeline pressure and material filling signal in real time. The sensor signal changes abruptly the moment the pile foundation is filled. The signal is sent to the signal processing module. The module immediately sends a closing command to the electronic discharge valve. The electronic discharge valve cuts off the discharge pipeline, and the concrete stops being discharged, realizing automatic valve closure when the grouting pipe is full.

[0064] The third control logic: The operator remotely sends a steering command, and the signal processing module drives the execution motor of the steering device 5 to complete the front wheel steering adjustment. The transfer and positioning are more flexible. The three control logics operate independently. Material level control and transfer, grouting control and material feeding, and walking and steering do not interfere with each other. There will be no confusion in pushing, valve closing and steering actions, and the stability of electrical control operation is greatly improved.

[0065] The control component utilizes a wireless receiver control device 7 to support both local wired control and remote wireless control modes. The wired mode is suitable for close-range maintenance and debugging, while the wireless mode is suitable for normal construction on slopes from a distance, adapting to different work scenarios.

[0066] In this embodiment, the battery 6 is installed in the spare frame position of the wheeled chassis. The battery 6 has sufficient capacity to ensure the continuous operation of the entire set of sensing, electronic control, steering device 5 and drive hardware around the clock. The entire set of equipment can be used normally in mountainous areas without external power supply, and the equipment has stronger adaptability to the field. All wiring points of sensors, drive components, steering device 5 and valves are uniformly stored and routed. The pipelines are bundled and fixed along the chassis frame. The pipelines will not drag and wear on the ground when walking on slopes and turning, reducing the probability of line failure.

[0067] A second aspect of this invention provides a method for pouring anti-slip and anti-tilting photovoltaic piles in mountainous areas using a material level monitoring system. The method employs the material level monitoring anti-slip and anti-tilting photovoltaic pile pouring dump truck system described above, and includes: The operators transferred the entire pouring bucket truck system to the flat platform area at the top of the working slope 11, completed the hardware pre-inspection, and checked that the anti-skid tires, telescopic spikes, telescopic support arms, steering device 5, various sensors, electric valves, and electric push rod wiring were intact and undamaged.

[0068] Then, operate the traction unit 10 to secure one end of the traction wire rope to the traction lug at the front of the wheeled chassis, and wind the other end of the wire rope into the traction equipment drum, confirming that the traction connection is secure and there is no risk of slippage. After all hardware checks are completed, start the external concrete conveying equipment, align the conveying pipeline with the top of hopper 1, and prepare to add concrete to hopper 1. During the alignment process on level ground, the steering device 5 can be remotely controlled to adjust the angle of the vehicle head, precisely aligning with the discharge position of the conveying pipeline.

[0069] The external conveying equipment continuously pumps concrete into hopper 1. The contact level probe on the inner wall of hopper 1 continuously collects the liquid level signal in real time, and the signal is continuously transmitted to the control component equipped with wireless receiving and control device 7.

[0070] When the concrete level rises and touches the contact level probe, it means that the hopper 1 has reached its maximum capacity. The signal processing module inside the control component receives the level signal and simultaneously sends a start command to the push drive device. Relying on the DC motor drive device 4, the electric push rod is driven to extend forward. The end of the electric push rod presses against the front end of the wheeled chassis, stably pushing the whole vehicle to move at a constant speed towards the working slope 11. During the push, the steering device 5 can be finely adjusted as needed to correct the walking route.

[0071] When the wheeled chassis moves to the top of the working slope 11, the position sensor signal is transmitted back to the control component. The control component cuts off the power to the push rod, the electric push rod retracts and resets, the pushing action stops, and the whole vehicle stops at the top of the slope.

[0072] The entire filling process requires no manual supervision of the hopper; it automatically pushes the material when full, preventing overflow and saving labor.

[0073] During the slope transfer phase, the electric push rod is released, and the operator starts the traction unit 10. The traction equipment retracts the traction steel cable, and the wheeled chassis is pulled down the working slope 11 by the tension of the steel cable. During travel, the direction of the front wheels can be finely adjusted by the steering device 5 to adapt to slope curves and raised terrain. If the slope is rainy, snowy, muddy, or icy, the internal telescopic serrations of the anti-skid tires are extended in advance. The serrations penetrate the mud and ice to prevent slippage and the tires from spinning freely.

[0074] Throughout the transport process, the wheeled chassis with telescopic support arms on both sides lowers to contact the slope, forming a double-sided support to prevent rollover. Even on bumpy or undulating slopes, the vehicle's tilt angle is strictly limited, preventing overturning. The traction unit's first traction device 8 and second traction device 9 can be selected for single-unit or dual-unit synchronous traction depending on the slope length and gradient, ensuring sufficient traction force and smooth, controllable transport on slopes. Operators can remotely control the traction start / stop and steering device 5 without having to accompany the vehicle downhill.

[0075] During the grouting connection and automatic feeding stage, after the trolley is pulled to the designated grouting point of the photovoltaic pile, the equipment stops and the operator remotely controls the steering device 5 to finely adjust the vehicle's position to facilitate the alignment of the discharge pipe; the construction personnel manually connect and tie the discharge port 2 at the end of the discharge pipe to the pre-embedded grouting hose of the photovoltaic pile to ensure that the pipe opening is sealed and does not leak grout.

[0076] After docking, the operator sends an activation signal to the control component via remote control. The signal processing module controls the electronic discharge valve inside the discharge control device 3 to open. The concrete inside the hopper 1 flows into the photovoltaic pile through the discharge pipe and discharge port 2 by its own weight to carry out grouting. Throughout the grouting process, the grouting detection sensor at the discharge port 2 monitors the concrete filling status in real time and continuously sends the detection signal back to the control component.

[0077] In the final stage of grouting, the inside of the photovoltaic pile is filled with concrete. The grouting detection sensor captures the filling signal and transmits it to the control component. The signal processing module immediately outputs a power-off valve closing signal, the electronic discharge valve quickly closes, the discharge pipeline is cut off, the concrete pouring stops, and the grouting operation of this photovoltaic pile is completed.

[0078] The operator releases the traction wire rope clamp, returns the tractor to the platform, cleans the residual concrete from the inner wall of hopper 1, and prepares to begin the next photovoltaic pile pouring cycle. The entire process relies on the equipment's electronic control linkage, replacing manual judgment, manual pushing, manual valve opening and closing, and manual maneuvering and steering with automated control. The entire process is standardized, ensuring stable construction quality, reducing manpower input, and significantly improving the reliability of operations in complex mountainous conditions.

[0079] This embodiment features a weather-resistant design for open-air photovoltaic construction in mountainous areas. The wheeled walking structure protects the turf, meeting the requirements for soil and water conservation and ecological management in mountainous photovoltaic projects. The anti-slip and puncture-resistant structure adapts to rain, snow, and icy weather, enabling uninterrupted construction around the clock. Double-sided telescopic support arms address the risk of rollover on steep slopes, improving the safety factor of field operations. Steering device 5 gives the dump truck flexible steering capabilities in mountainous terrain, adapting to precise positioning on narrow working surfaces. Material level sensing closed-loop control eliminates overflow and waste, accurately controlling the amount of concrete loaded per batch. The push-drive device automates the delivery of the truck uphill, solving the problem of low efficiency caused by manual pushing in large areas. The discharge pipe features dual sensors and an electrically controlled valve, automatically closing the valve based on grouting signals, completely avoiding quality problems such as broken piles and over-grouting caused by manual grouting control.

[0080] The traction unit 10 features a dual traction device with a detachable wire rope structure, making it easy to assemble and disassemble for multi-point relocation in mountainous areas; the hopper 1 is assembled with a bolt-on detachable bracket, making maintenance and cleaning convenient; all electrical controls are remotely managed by the wireless receiving control device 7, which can remotely control the steering device 5, push, and valves, keeping personnel away from dangerous slopes and increasing safety; the independent signal processing channel inside the control components ensures that multiple actions are linked without disorder and that the electrical control failure rate is low.
