Description

Technical Field

[0001] This utility model belongs to the field of water spraying and maintenance technology, and specifically relates to a prefabricated factory water spraying and maintenance vehicle. Background Technology

[0002] In the current context of the rapid development of the prefabricated building industry, prefabricated factories, as the core sites for the production of prefabricated components, directly determine the structural safety and service life of subsequent building projects based on the quality of the prefabricated components produced. After the prefabricated components are formed, they need to be regularly watered to maintain a suitable humidity environment. This process is a key link in ensuring the strength development of the components, reducing crack formation, and improving overall performance. Therefore, the stability and effectiveness of the watering and curing process has become an important control point in the production management of prefabricated factories.

[0003] However, the current watering and curing methods for prefabricated components in prefabricated factories still have many problems that urgently need to be solved, making it difficult to meet the demands of efficient and high-quality production. On the one hand, most factories still rely on manual watering with hand-held hoses. This method requires operators to continuously move around the component storage area with a water hose. For factories with large areas and a large number of components, operators need to work back and forth for long periods of time, resulting in extremely high labor intensity. At the same time, the coverage and frequency of manual watering depend entirely on the experience and physical strength of the operators. This not only easily leads to missed areas or repeated watering, making it difficult to ensure the uniformity of watering and thus affecting the curing quality of some components, but also has obvious efficiency shortcomings, making it impossible to quickly complete the curing of large-scale components and slowing down the overall production process.

[0004] On the other hand, some large-scale prefabricated factories use traditional water trucks for watering and maintenance. While these trucks can reduce labor intensity and improve work efficiency to some extent, they have significant energy consumption issues during operation. Traditional water trucks are usually powered by fuel, resulting in high fuel consumption during operation. This not only increases the factory's operating costs but also emits exhaust gases, causing environmental impact. Even if some water trucks use mains power, the overall power consumption is still high and lacks energy-saving design, still resulting in high energy consumption and insufficient flexibility. They are difficult to adapt to the complex component storage layout and diverse maintenance needs within prefabricated factories. Existing watering and maintenance methods for prefabricated components in prefabricated factories have significant shortcomings in terms of labor intensity, work efficiency, watering uniformity, and energy consumption control, failing to fully meet the actual needs of factories for efficient, energy-saving, and high-quality maintenance. Therefore, design improvements are necessary. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a prefabricated factory water spraying and maintenance vehicle to solve the problems raised in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A prefabricated factory water spraying and maintenance vehicle includes a vehicle body, a photovoltaic power generation mechanism fixedly installed in the middle of the top of the vehicle body, a water tank fixedly installed on the rear side of the vehicle body, and a water spraying mechanism fixedly installed on the rear side of the water tank. The water spraying mechanism and the photovoltaic power generation mechanism are connected by a belt drive module.

[0008] The water spraying mechanism includes a mounting groove located on the upper back of the water tank. A water pump is fixedly installed inside the mounting groove. A rotary joint is fixedly installed at the output end of the water pump. A delivery pipe is rotatably connected to the output end of the water pump through the rotary joint. A spray pipe frame is fixedly installed at the outer end of the delivery pipe. Sprinkler nozzles are fixedly installed at equal intervals in a linear arrangement at the outer output end of the spray pipe frame. The input end of the sprinkler nozzle is connected to the output end of the spray pipe frame.

[0009] As a preferred technical solution, a housing is fixedly installed at the top front end of the vehicle body, and a storage battery is fixedly installed inside the housing.

[0010] As a preferred technical solution, a mounting base is fixedly installed on one side of the top of the water tank, and a liquid level sensor is installed on the mounting base. The liquid level detection end of the liquid level sensor is located inside the water tank.

[0011] As a preferred technical solution, a water filling connection valve is fixedly installed on the upper side of one side of the water tank, and an external water pipe connector is fixedly installed on the outer input end of the water filling connection valve.

[0012] As a preferred technical solution, the photovoltaic power generation mechanism includes a circular base, which is fixedly installed on the top front end of the vehicle body. A first motor is fixedly installed on the inner side of the circular base, and a shaft is fixedly installed on the output end of the first motor. An angle adjustment module is fixedly installed on the top of the shaft.

[0013] As a preferred technical solution, the pulley drive module includes a first pulley and a second pulley. The first pulley is fixedly installed on the upper part of the outer surface of the shaft, and the second pulley is fixedly installed on the lower part of the outer surface of the conveying pipe. The first pulley and the second pulley are connected by a drive belt.

[0014] As a preferred technical solution, the angle adjustment module includes a turntable, which is fixedly installed on the top of the shaft. A concave seat is fixedly installed on the top of the turntable. A rotating shaft is rotatably connected to the upper end of the concave seat. A connecting plate is fixedly installed on the top of the rotating shaft. An arc-shaped plate is fixedly installed on the top of the connecting plate. An arc-shaped photovoltaic panel is fixedly installed on the top of the arc-shaped plate. A second motor is fixedly installed at one end of the concave seat, and the output end of the second motor is connected to one end of the rotating shaft.

[0015] In summary, the present invention has the following main advantages:

[0016] Firstly, during the application of this technical solution, by setting up an automated water spraying mechanism in conjunction with a pulley drive module, the first motor can control the rotation of the spray pipe frame during use. This, combined with the linearly arranged spray nozzles, enables large-area uniform water spraying. Operators do not need to hold the water hose; they only need to control the equipment's start-up and shutdown and parameter adjustments. This reduces labor intensity and improves water spraying efficiency and uniformity. At the same time, by setting up a liquid level sensor, the water level in the tank can be monitored in real time, preventing work interruptions due to insufficient water. This ensures continuous maintenance and solves the problems of high labor intensity, low efficiency, and poor uniformity in manual water spraying in existing technologies.

[0017] Secondly, during the application of this technical solution, by setting up a photovoltaic power generation mechanism in conjunction with a storage battery, and by adjusting the photovoltaic angle after the vehicle stops to generate standby power, solar energy can be converted into electrical energy during use, reducing dependence on fuel or mains power, thereby achieving the effect of reducing energy consumption and operating costs and avoiding fuel pollution. By setting the photovoltaic power generation mechanism and the water spraying mechanism to share a single drive system, the structure can be simplified and the usage cost can be reduced, thereby achieving the effect of controlling equipment costs. Powered by a storage battery, the vehicle can move freely to adapt to complex component layouts, and while driving, the first motor can alternately operate to achieve oscillating spraying, thereby improving the flexibility of use and solving the problems of high energy consumption, insufficient flexibility, and high cost of traditional water trucks in the prior art.

[0024] Example

[0025] refer to Figures 1 to 5 This embodiment of a prefabricated factory water spraying and maintenance vehicle includes a vehicle body 1, a photovoltaic power generation mechanism 2 fixedly installed in the middle of the top of the vehicle body 1, a water tank 3 fixedly installed on the rear side of the vehicle body 1, a water spraying mechanism 4 fixedly installed on the rear side of the water tank 3, and the water spraying mechanism 4 and the photovoltaic power generation mechanism 2 are connected by a pulley drive module 5.

[0026] The sprinkler mechanism 4 includes a mounting groove 41 located at the upper back of the water tank 3. A water pump 42 is fixedly installed inside the mounting groove 41. A rotary joint 43 is fixedly installed at the output end of the water pump 42. A delivery pipe 44 is rotatably connected to the output end of the water pump 42 via the rotary joint 43. A spray pipe bracket 45 is fixedly installed at the outer end of the delivery pipe 44. Sprinkler nozzles 46 are fixedly installed at equal intervals in a linear arrangement at the outer output end of the spray pipe bracket 45. The input end of the sprinkler nozzles 46 is connected to the output end of the spray pipe bracket 45. During application, the vehicle body 1, photovoltaic power generation mechanism 2, water tank 3, sprinkler mechanism 4, and pulley drive module 5 work together to provide a unified support structure for the components. The vehicle body 1 serves as the mounting base for all components. The water tank 3, fixed to the rear of the vehicle body 1, stores the water needed for sprinkling, meeting the water requirements for maintenance operations. When the sprinkler mechanism 4 is running, the water pump 42 inside the mounting slot 41 starts, drawing water from the water tank 3. The rotary joint 43 at the output end of the water pump 42 ensures a stable water flow during the rotation of the delivery pipe 44. To prevent damage to the pipeline due to rotation and twisting, water flows through the delivery pipe 44 to the spray pipe frame 45. The sprinkler heads 46, evenly spaced on the outside of the spray pipe frame 45, are connected to the inside of the frame, evenly spraying water onto the surface of the precast components for curing. The photovoltaic power generation mechanism 2 can collect solar energy and convert it into electrical energy to power the device. Simultaneously, it is connected to the spraying mechanism 4 via the pulley drive module 5, driving the delivery pipe 44 and the spray pipe frame 45 to rotate, thus widening the spraying range of the sprinkler heads 46 and covering more precast components. The automated water spraying structure reduces manual intervention and lowers the labor intensity of operators. The belt drive module 5 drives the spray pipe frame 45 to rotate, improving water spraying efficiency and coverage. The uniform arrangement of the water spray nozzles 46 ensures water spraying uniformity and avoids uneven component curing. The photovoltaic power generation mechanism 2 reduces dependence on traditional energy sources, lowering energy consumption and operating costs. The synergistic effect of all structures allows the device to operate efficiently and stably in the curing of prefabricated components in the prefabricated factory.

[0027] refer to Figures 1-3A housing 6 is fixedly installed at the top front of the vehicle body 1, and a battery is fixedly installed inside the housing 6. A mounting base 7 is fixedly installed on one side of the top of the water tank 3, and a liquid level sensor 8 is installed on the mounting base 7. The liquid level detection end of the liquid level sensor 8 is located inside the water tank 3. A water filling connection valve 9 is fixedly installed on the upper side of one side of the water tank 3, and an external water pipe connector 10 is fixedly installed on the outer input end of the water filling connection valve 9. During the application of this device, by setting up the housing 6, battery, mounting base 7, liquid level sensor 8, water filling connection valve 9, and external water pipe connector 10, in conjunction with the original structure of the vehicle body 1 and water tank 3, the housing 6 at the top front of the vehicle body 1 provides protection for the internal battery during use, preventing the battery from being affected by external collisions and dust. The battery can store electrical energy and provide stable power support for the various electrical components of the device, ensuring the normal operation of the water pump 42, transmission structure, etc. The mounting base 7 on one side of the top of the water tank 3 is used to fix the liquid level sensor 8, and the detection end of the liquid level sensor 8 extends into the water tank 3. The device can monitor the water level in water tank 3 in real time. When the water level is low, it can promptly remind operators to add water to avoid interruptions in watering operations due to water shortage, thus ensuring the continuity of maintenance work. The water filling connection valve 9 on the upper side of water tank 3 is used to connect to an external water source. Its external water pipe connector 10 can quickly connect to an external water pipe, simplifying the water filling process, reducing water filling time, and allowing operators to quickly complete the water filling of water tank 3, improving the ease of use of the device. During the entire maintenance operation, the presence of the battery reduces the dependence on external power, allowing the device to move flexibly within the factory without being limited by power lines. The real-time monitoring function of the liquid level sensor 8 avoids blind water filling or shutdown due to water shortage, improving work efficiency. The cooperation between the water filling connection valve 9 and the external water pipe connector 10 makes the water filling process more efficient and reduces waiting time. These components work together with the original structure to further improve the practicality and stability of the device in the maintenance of prefabricated components in prefabricated factories, reduce the difficulty of operation, and ensure the continuous and efficient operation.

[0028] refer to Figures 1-5The photovoltaic power generation mechanism 2 includes a circular base 21, which is fixedly installed on the top front end of the vehicle body 1. A first motor 22 is fixedly installed on the inner side of the circular base 21. A shaft 23 is fixedly installed on the output end of the first motor 22. An angle adjustment module 24 is fixedly installed on the top of the shaft 23. The belt drive module 5 includes a first pulley 51 and a second pulley 52. ​​The first pulley 51 is fixedly installed on the upper outer surface of the shaft 23, and the second pulley 52 is fixedly installed on the lower outer surface of the conveying pipe 44. The first pulley 51 and the second pulley 52 are connected by a drive belt 53. The angle adjustment module 24 includes a turntable 241, which is fixedly installed on the top of the shaft 23. A concave seat 242 is fixedly installed on the top of the turntable 241. A rotating shaft 243 is rotatably connected to the upper part of the inner part of the base 242. A connecting plate 244 is fixedly installed on the top of the rotating shaft 243. An arc-shaped plate 245 is fixedly installed on the top of the connecting plate 244. An arc-shaped photovoltaic panel 246 is fixedly installed on the top of the arc-shaped plate 245. A second motor 247 is fixedly installed at one end of the concave base 242. The output end of the second motor 247 is connected to one end of the rotating shaft 243. During the application of this device, by setting up the photovoltaic power generation mechanism 2 and the pulley transmission module 5, in conjunction with the original structure of the vehicle body 1 and the conveying pipe 44, the circular base 21 of the photovoltaic power generation mechanism 2 provides a mounting base for the internal components. After the first motor 22 inside the circular base 21 is started, its output end drives the shaft 23 to rotate. The top of the shaft 23... The angle adjustment module 24 operates synchronously. In the angle adjustment module 24, the turntable 241 at the top of the shaft 23 drives the concave seat 242 at the top to rotate. The second motor 247 at one end of the concave seat 242 starts, and the output end drives the internal rotating shaft 243 to rotate. The connecting plate 244 at the top of the rotating shaft 243 rotates accordingly, thereby driving the arc-shaped plate 245 and the arc-shaped photovoltaic panel 246 at the top of the connecting plate 244 to adjust their tilt angle. The first motor 22 adjusts the horizontal orientation of the arc-shaped photovoltaic panel 246, and the second motor 247 adjusts the tilt angle, so that the arc-shaped photovoltaic panel 246 can better receive sunlight and convert solar energy into electrical energy to provide power for the operation of the device. At the same time, when the shaft 23 rotates, the first pulley 51 at the upper end of its outer surface rotates synchronously. The first motor 22 drives the second pulley 52 to rotate via the transmission belt 53, which in turn drives the delivery pipe 44 to rotate. This allows the spraying structure at the outer end of the delivery pipe 44 to adjust its spraying direction and expand the water coverage area. Throughout the process, the bidirectional adjustment function of the angle adjustment module 24 improves the solar energy absorption efficiency of the arc-shaped photovoltaic panel 246 and ensures the stability of the power supply. The pulley drive module 5 uses the power of the first motor 22 to rotate the delivery pipe 44, eliminating the need for additional drive components and simplifying the device structure. The combined effect of the two provides clean energy support for the device, enhances the flexibility and coverage of the water spraying operation, reduces dependence on traditional energy sources and the cost of device use, and further optimizes the maintenance effect of prefabricated components in the prefabricated factory.

[0029] Operating Principle and Advantages: When using this prefabricated factory water spraying and maintenance vehicle, initial equipment preparation and energy storage are carried out first. In daily application scenarios, after the vehicle stops, the photovoltaic power generation mechanism 2 will be adjusted to the optimal angle for receiving sunlight. Because this device is mostly activated only when water spraying is needed and is in standby mode most of the time, simply parking the vehicle in the sunniest location and adjusting the angle of the arc-shaped photovoltaic panel 246 will allow for continuous auxiliary power generation. The vehicle body 1 serves as the overall support structure, with a housing 6 installed at its top front end. The housing 6 houses a battery, which effectively stores electrical energy and provides stable power to all electrical components of the vehicle. The photovoltaic power generation mechanism 2, located in the middle of the top of the vehicle body 1, is responsible for acquiring solar energy and converting it into electrical energy. When the photovoltaic power generation mechanism 2 is running, the first motor 22 inside the circular seat 21 starts, directly driving the shaft 23 to rotate. The angle adjustment module 24 on top of the shaft 23 will also rotate accordingly. The concave seat 242 of the angle adjustment module 24 is fixed. The turntable 241, fixed at the top of the shaft 23, rotates when the second motor 247 at one end of the concave seat 242 starts. This rotates the internal shaft 243, and the connecting plate 244 at the top of the shaft 243 in turn drives the arc-shaped plate 245 and the arc-shaped photovoltaic panel 246 to adjust their tilt angles. The first motor 22 adjusts the horizontal orientation of the arc-shaped photovoltaic panel 246, and the second motor 247 adjusts its tilt angle, so that the arc-shaped photovoltaic panel 246 can receive sunlight to the maximum extent, efficiently converting solar energy into electrical energy and storing it in the battery. The water tank 3 on the rear side of the vehicle body 1 is used to store the water needed for watering. When water needs to be added, the water source is connected through the water addition connection valve 9 on the upper side of the water tank 3. The external water pipe connector 10 on the outside of the water addition connection valve 9 can be quickly connected to the external water pipe to achieve efficient water addition operation. A liquid level sensor 8 is installed on the mounting base 7 on the top side of the water tank 3. The detection end of the liquid level sensor 8 extends into the water tank 3 and can monitor the water volume in the water tank 3 in real time, so that the operator can understand the water level in time and avoid the maintenance operation due to insufficient water.

[0030] Next, the angle and transmission are adjusted before watering. The photovoltaic power generation mechanism 2 and the watering mechanism 4 of this device use the same drive system. This design significantly reduces operating costs. When the shaft 23 of the photovoltaic power generation mechanism 2 rotates, the first pulley 51 on its outer surface rotates synchronously, driving the second pulley 52 to rotate via the transmission belt 53. The second pulley 52 is fixed to the lower end of the outer surface of the delivery pipe 44 of the watering mechanism 4, thus driving the delivery pipe 44 to rotate. In the watering mechanism 4, a water pump 42 is fixed inside the mounting groove 41. The output end of the water pump 42 is rotatably connected to the delivery pipe 44 via a rotary joint 43. The rotary joint 43 ensures that the delivery pipe 44 rotates smoothly. Water is delivered normally, preventing pipes from being twisted and damaged due to rotation; the spray pipe frame 45 at the outer end of the delivery pipe 44 rotates synchronously with the delivery pipe 44, allowing for flexible adjustment of the horizontal spraying direction to cover prefabricated components in different areas. At the same time, according to the actual distribution of prefabricated components, the second motor 247 drives the rotating shaft 243 to rotate, and the connecting plate 244 drives the arc plate 245 and the arc photovoltaic panel 246 to adjust their angles. If it is necessary to fine-tune the height of the spray pipe frame 45, the rotation speed of the shaft 23 can be controlled by the first motor 22 to indirectly adjust the rotation speed of the delivery pipe 44, thereby controlling the rotation frequency of the spray pipe frame 45 to ensure that the spraying range is precisely matched with the component storage area.

[0031] The water spraying operation is then initiated. If oscillating spraying is required while the vehicle is in motion, simply start the first motor 22 to rotate alternately in both forward and reverse directions to assist in oscillating spraying. Since the water spraying operation on the vehicle body 1 takes a short time and is mostly in a standby state, the efficiency loss of the photovoltaic panels during driving is negligible. After all adjustments are completed, the water pump 42 is started. The water pump 42 draws water from the water tank 3, and the water flows through the output end of the water pump 42 into the rotary joint 43, and then through the delivery pipe 44 to the spray pipe frame 45. Spray nozzles are linearly arranged on the outer output end of the spray pipe frame 45. 46. ​​The sprinkler head 46 is kept in communication with the inside of the spray pipe frame 45. Water flows through the sprinkler head 46 and is evenly sprayed onto the surface of the precast components to achieve curing. During the watering process, the rotation state of the delivery pipe 44 can be adjusted by controlling the start and stop of the first motor 22. When it is necessary to spray a specific area, the first motor 22 is stopped so that the spray pipe frame 45 keeps a fixed direction. When it is necessary to spray a large area evenly, the first motor 22 is started, and the delivery pipe 44 drives the spray pipe frame 45 to rotate continuously. The sprinkler head 46 rotates with the spray pipe frame 45, effectively expanding the watering coverage area and ensuring that the precast components in different positions can be fully cured.

[0032] This device features an automated water spraying structure, eliminating the need for operators to hold water hoses. Operators only need to control the equipment's start / stop and adjust parameters, significantly reducing labor intensity. The spray pipe frame 45, combined with linearly arranged spray nozzles 46, can quickly cover large areas. The fixed rotation speed of the spray pipe frame 45 and the fixed nozzle spacing ensure uniform water spraying, effectively solving the problems of low efficiency and poor uniformity in manual water spraying. Furthermore, by incorporating a photovoltaic power generation mechanism 2 in conjunction with a battery, and prioritizing photovoltaic angle adjustment after the vehicle stops while maintaining standby power generation, solar energy is converted into electrical energy to power the equipment. This reduces reliance on fuel or mains power, lowering energy consumption and operating costs, while also avoiding fuel pollution. Battery power also allows the vehicle to move freely within the factory, adapting to complex component storage layouts and addressing the high energy consumption and lack of flexibility issues of traditional water trucks. The photovoltaic power generation mechanism 2 and the water spraying mechanism 4 share a single drive system, further reducing operating costs. During operation, the first motor 22 alternates between different positions to achieve oscillating spraying, resulting in short spraying time and negligible photovoltaic efficiency consumption. This balances operational needs with energy utilization. The liquid level sensor 8 monitors the water level in real time, ensuring continuous operation. The rotary joint 43 ensures stable water spraying and prevents pipeline damage. The angle adjustment module 24, through the cooperation of the first motor 22 and the second motor 247, improves the solar energy absorption efficiency of the arc-shaped photovoltaic panel 246, ensuring sufficient power. The pulley drive module 5 simplifies the power transmission structure and reduces energy consumption. The chassis 6 protects the battery, which powers the equipment even without sunlight, ensuring uninterrupted operation. The coordinated operation of all components significantly improves the stability and practicality of the device.
