Description

Technical Field

[0001] This utility model relates to the field of monitoring device technology, and in particular to a real-time monitoring device for compaction degree during asphalt pavement construction. Background Technology

[0002] In asphalt pavement construction, compaction degree is a key indicator for measuring pavement quality. Insufficient compaction degree can lead to premature pavement damage, such as rutting and cracking, which seriously affects the service life of the road and driving safety.

[0003] Utility model patent CN215948138U discloses a real-time monitoring device for roadbed and pavement compaction. The device includes a shell with an open bottom, a first groove on the shell, and two symmetrically arranged second grooves inside the shell, which are interconnected. A reversible motor is threadedly connected to one side of the outer wall of the shell, with the motor output shaft extending into the first groove and fixedly connected to a rotating rod. Two first bevel gears are symmetrically fixed to the outer wall of the rotating rod, meshing with the second bevel gears, and a threaded rod is fixedly connected to the inner wall of the second bevel gears. The threaded rod is rotatably mounted inside the second groove, with a threaded sleeve threaded onto its outer wall, and a connecting block welded to the bottom of the threaded sleeve. A roller is rotatably connected to the inner wall of the shell, and the connecting block is rotatably connected to the outer wall of the roller on the side away from the second groove. The upper and lower surfaces of the roller are provided with equidistantly arranged third grooves, and compaction sensors are installed on the inner walls of the third grooves.

[0004] The aforementioned utility model patent describes a technical solution that moves the device by pushing a handle or using a tractor, thereby utilizing a compaction sensor to detect road conditions. This solution not only saves manpower and time but also improves project progress. However, in practical applications, this solution lacks a self-cleaning function, causing the pores in the third groove to be easily clogged by road debris and other impurities, thus affecting the detection accuracy of the compaction sensor. Utility Model Content

[0005] In view of this, in order to solve the technical problem that existing real-time monitoring devices for roadbed and pavement compaction do not have a cleaning function, this utility model provides a real-time monitoring device for compaction during asphalt pavement construction. Through a cleaning mechanism, the surface of the compaction sensor is preliminarily and deeply cleaned, which can effectively realize the cleaning function of the compaction sensor, improve the detection accuracy of the compaction sensor, and has high practical value.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A real-time monitoring device for compaction degree during asphalt pavement construction includes:

[0008] The chassis has a pair of retainers on one side;

[0009] The roller body is rotatably connected to the inner side of the cage, and has several grooves on its outer side;

[0010] A cleaning rack is disposed in the groove and has several through holes thereon;

[0011] The compaction sensor has one end slidably connected to the through hole, and the other end is used to monitor the road surface condition in real time.

[0012] A cleaning mechanism, located on one side of the chassis, includes an adjustment mechanism for adjusting the position of the retainer to perform preliminary cleaning of the surface of the compaction sensor, and a deep cleaning mechanism for performing deep cleaning of the surface of the compaction sensor.

[0013] Preferably, the deep cleaning mechanism includes:

[0014] The mobile rack is equipped with a cleaning device on one side.

[0015] A first driving device is used to drive the moving frame to move the cleaning device along the extension direction of the retainer in order to clean the surface of the compaction sensor.

[0016] Preferably, it further includes:

[0017] Slide rails are respectively disposed on a pair of the aforementioned cages;

[0018] The sliders are respectively disposed at both ends of the movable frame and are slidably connected to the slide rail.

[0019] Preferably, the adjustment mechanism includes:

[0020] A bidirectional threaded rod, the two ends of which are rotatably connected to the two sides inside the roller body;

[0021] Movable blocks are respectively fitted onto both ends of the bidirectional threaded rod and can move along the extension direction of the bidirectional threaded rod;

[0022] The push rod has one end disposed in the groove and can slide along the groove, and the other end is fixedly connected to the retainer;

[0023] The connecting rod is hinged at one end to the movable block and at the other end to the push rod;

[0024] The second driving device has its output end connected to the bidirectional threaded rod, which drives the bidirectional threaded rod to rotate and move the movable fast movement, thereby moving the cage through the connecting rod and push rod to adjust the position of the cage.

[0028] Preferably, a control panel is provided on one end face of the chassis, and a signal transceiver is provided on the top of the chassis.

[0029] Preferably, the chassis is provided with a handle, and the other side of the chassis is provided with a traction seat.

[0030] The real-time compaction monitoring device for asphalt pavement construction provided by this utility model effectively cleans the surface of the compaction sensor through a cleaning mechanism, improving the sensor's detection accuracy and thus possessing high practical value. Compared to existing technologies, it offers the following advantages:

[0031] This invention features a roller body rotatably connected to the inner side of a retainer, providing rotational support for the roller body and ensuring that the roller body can roll stably on the asphalt pavement, thereby achieving efficient compaction operations.

[0032] Several compaction sensors are installed inside the groove, which can sense the compaction pressure of the asphalt pavement in real time and convert it into an electrical signal, providing a reliable basis for the subsequent analysis and processing of compaction data.

[0033] A cleaning rack is fitted around the outside of the compaction sensor to perform preliminary cleaning of the sensor surface, thereby pushing debris out of the groove and ensuring the normal operation of the sensor.

[0034] The device is equipped with casters on both sides of the bottom of the chassis, giving it excellent mobility and facilitating rapid transfer between different construction areas, thus improving its flexibility and work efficiency.

[0035] By using a bidirectional threaded rod, a movable block, a connecting rod, a push rod, and a motor, the motor drives the bidirectional threaded rod to rotate, which in turn moves the movable block. This causes the connecting rod to slide the push rod within the groove, thereby adjusting the position of the cleaning frame. This cleans the surface of the compaction sensor and pushes out debris from the groove, ensuring the sensor functions properly.

[0036] By installing electric slip rings on the inner side of the side frame, stable power supply and signal transmission for the motor and compaction sensor can be ensured during the rotation of the roller, avoiding the problem of wire entanglement.

[0037] By using a movable frame, cleaning brush, slider, slide rail, and electric telescopic rod, the electric telescopic rod pushes the movable frame, causing the slider to slide on the slide rail, which in turn drives the cleaning brush to perform deep cleaning on the surface of the compaction sensor, thereby further improving the sensor's detection accuracy.

[0038] By installing a counterweight on the outside of the limiting post, the pressure of the device on the road surface can be adjusted to meet the needs of monitoring different compaction degrees and improve the accuracy of the monitoring results.

[0039] The device is powered by a lithium battery installed inside the chassis, ensuring it can operate independently on the construction site. A charging port on the top of the chassis allows the lithium battery to be charged, ensuring the device is always ready for use.

[0040] A handle is installed on the top of the chassis, making it easy for operators to manually push the device to move. A traction seat is installed on the other side of the chassis, which can be connected to external traction equipment to realize the traction movement of the device, increasing the versatility of the device's movement methods. A control panel is installed on one end of the chassis, which allows for operation and parameter setting of the device, increasing the ease of use of the product.

[0041] The top of the chassis is equipped with a signal transceiver, which can transmit compaction monitoring data to the monitoring center or other relevant equipment in real time, facilitating remote monitoring and data analysis.

[0042] In summary, this invention can effectively achieve self-cleaning function, improve the detection accuracy of compaction sensor, and has high practical value. Attached Figure Description

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0052] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0053] like Figure 1-5 As shown, this utility model provides a real-time monitoring device for compaction degree during asphalt pavement construction, comprising:

[0054] The housing 100 has a pair of retainers 101 on one side. The retainers 101 on both sides of the housing 100 provide rotational support for the roller 102 described below, enhancing the structural stability of the housing 100 and providing precise rotational support for the roller 102. The retainers 101 ensure stable rotation of the roller 102 during installation and operation, reducing friction and wear, thereby improving the overall system efficiency and lifespan. Furthermore, this design facilitates maintenance and replacement of the roller 102, reducing maintenance costs and time.

[0055] The roller body 102 is rotatably connected to the inner side of the retainer 101, and has several grooves 10201 on its outer side. These grooves 10201 provide a base for mounting the cleaning frame 104 and the compaction sensor 103, respectively; that is, both the cleaning frame 104 and the compaction sensor 103 are mounted inside the grooves 10201. The design of the grooves 10201 not only provides a stable foundation for the mounting of the cleaning frame 104 and the compaction sensor 103, but also ensures that these components can be precisely positioned and are easy to assemble and maintain. Furthermore, the design of the grooves 10201 helps to enhance the structural strength of the roller body 102, enabling it to maintain stable performance even under high-speed operation or high pressure. At the same time, this design also optimizes the overall layout of the roller body 102, making the cleaning and compaction functions more integrated and efficient, thus improving the equipment's working efficiency and reliability.

[0056] The cleaning rack 104, disposed within the groove 10201, has several through holes 10401 for mounting the compaction sensor 103 described below. This not only saves space but also ensures the compactness and stability of the structure. More advanced is the ingenious design of the through holes 10401 on the cleaning rack 104. These through holes 10401 not only facilitate the installation of the compaction sensor 103 but also ensure that the sensor can accurately monitor the required area, thereby greatly improving the accuracy and efficiency of monitoring. Furthermore, the design of the through holes 10401 also aids in ventilation and heat dissipation within the cleaning rack 104, extending the service life of the equipment.

[0057] The compaction sensor 103 has one end slidably connected within the through hole 10401, and the other end used for real-time monitoring of road surface conditions. Specifically, the slidable connection between the compaction sensor 103 and the through hole 10401 can be achieved by sliding between the inner side of the through hole 10401 and the outer side of the compaction sensor 103. This design, where one end of the compaction sensor 103 is slidably connected within the through hole 10401, allows the compaction sensor 103 to be adjusted in position as needed to adapt to different road surface monitoring requirements. The other end is directly used for real-time monitoring of road surface conditions, ensuring the accuracy and timeliness of the data. The specific implementation of this sliding connection, namely the sliding engagement between the inner side of the through hole 10401 and the outer side of the compaction sensor 103, further enhances the stability and durability of the sensor, enabling it to maintain efficient operation in various complex environments.

[0058] A cleaning mechanism, located on one side of the housing 100, includes an adjustment mechanism 105 for adjusting the position of the retainer 101 to perform preliminary cleaning of the surface of the compaction sensor 103, and a deep cleaning mechanism 115 for performing deep cleaning of the surface of the compaction sensor 103. The adjustment mechanism 105 precisely adjusts the position of the retainer 101 to ensure optimal preliminary cleaning of the surface of the compaction sensor 103. The deep cleaning mechanism 115 further thoroughly cleans the surface of the compaction sensor 103, ensuring long-term stable operation of the sensor and improving the overall performance and reliability of the equipment.

[0059] In this utility model, the deep cleaning mechanism 115 includes:

[0060] The movable frame 11501 has a cleaning device on one side. The cleaning device is preferably a cleaning brush 11502, or other cleaning tools in the art, and there are no special requirements for it.

[0061] A first driving device is used to drive the movable frame 11501 to move the cleaning device along the extension direction of the retainer 101 to clean the surface of the compaction sensor 103. Preferably, the first driving device is an electric telescopic rod 11505.

[0062] This utility model also includes:

[0063] Slide rails 11504 are respectively disposed on a pair of the retainers 101;

[0064] Slider 11503 is respectively disposed at both ends of the movable frame 11501 and slidably connected to the slide rail 11504.

[0065] like Figure 3 As shown, this utility model provides a specific embodiment of a deep cleaning mechanism 115, as follows:

[0066] The deep cleaning mechanism 115 includes a movable frame 11501, a cleaning brush 11502 is mounted on one side of the movable frame 11501, sliders 11503 are mounted on both ends of the movable frame 11501, slide rails 11504 are mounted on adjacent sides of a pair of retainers 101, the inner side of the slider 11503 and the outer side of the slide rail 11504 are slidably connected, and an electric telescopic rod 11505 is mounted on the inner side of the housing 100, the output end of the electric telescopic rod 11505 is connected to the other side of the movable frame 11501.

[0067] The advantages of the deep cleaning mechanism 115 of this utility model are mainly reflected in the following aspects:

[0068] First, the deep cleaning mechanism 115 effectively cleans the surface of the compaction sensor 103. The cleaning device on the moving frame 11501 can move along the extension direction of the retainer 101 under the drive of the first driving device, thereby ensuring that all areas of the surface of the compaction sensor 103 are thoroughly cleaned, improving cleaning efficiency and quality.

[0069] Secondly, the design of the slide rail 11504 and slider 11503 makes the movement of the moving frame 11501 more stable and smooth. The slide rail 11504 is respectively set on a pair of retainers 101, while the slider 11503 is respectively set at both ends of the moving frame 11501 and slidably connected to the slide rail 11504. This structure not only enhances the stability of the moving frame 11501, but also enables the moving frame 11501 to maintain a constant speed and direction during movement, further improving the cleaning effect.

[0070] In summary, this utility model, through its reasonable structural design, achieves efficient and thorough cleaning of the surface of the compaction sensor 103, while ensuring the stability and reliability of the cleaning process, thus possessing significant technical advantages.

[0071] In this utility model, the adjusting mechanism 105 includes:

[0072] The bidirectional threaded rod 10501 has two ends that are rotatably connected to the two sides inside the roller body 102, respectively.

[0073] Movable blocks 10502 are respectively sleeved on both ends of the bidirectional threaded rod 10501 and can move along the extension direction of the bidirectional threaded rod 10501;

[0074] The push rod 10504 has one end disposed in the groove 10201 and can slide along the groove 10201, and the other end is fixedly connected to the retainer 101;

[0075] The connecting rod 10503 is hinged at one end to the movable block 10502 and at the other end to the push rod 10504;

[0076] The second driving device has its output end connected to the bidirectional threaded rod 10501. It drives the bidirectional threaded rod 10501 to rotate, thereby causing the movable fast mover to move through the connecting rod 10503 and the push rod 10504, thus adjusting the position of the retainer 101. Preferably, the second driving device is a motor 10505.

[0077] like Figure 5 As shown, this utility model illustrates a specific embodiment of the adjusting mechanism 105, as detailed below:

[0078] The adjusting mechanism 105 includes a bidirectional threaded rod 10501, the two ends of which are rotatably connected to the inner sides of the roller body 102. Movable blocks 10502 are fitted onto both ends of the bidirectional threaded rod 10501. Several connecting rods 10503 are hinged to the outer sides of the movable blocks 10502. A push rod 10504 is hinged to one end of each connecting rod 10503. Sliding openings 10202 are provided on both sides of the bottom end of the groove 10201. The outer side of the push rod 10504 is slidably connected to the inner side of the sliding opening 10202. One outer end of a pair of push rods 10504 is fixedly connected to both ends of the cleaning frame 104. A motor 10505 is installed at one end of the roller body 102, and the output end of the motor 10505 is connected to one end of the bidirectional threaded rod 10501.

[0079] The advantages of the adjustment mechanism 105 of this utility model are mainly reflected in the following aspects:

[0080] The adjustment mechanism 105 achieves precise adjustment of the position of the retainer 101 (or cleaning rack 104) through a clever combination of a bidirectional threaded rod 10501, a movable block 10502, a push rod 10504, a connecting rod 10503, and a second drive device (preferably a motor 10505). The two ends of the bidirectional threaded rod 10501 are rotatably connected to both sides of the inside of the roller body 102. When the motor 10505 drives the bidirectional threaded rod 10501 to rotate, the movable block 10502 can move along the extension direction of the bidirectional threaded rod 10501. Since the movable block 10502 and the push rod 10504 are hinged together by the connecting rod 10503, the movement of the movable block 10502 will cause the push rod 10504 to slide along the groove 10201, thereby pushing or pulling the retainer 101 (or cleaning rack 104) to move, achieving the purpose of position adjustment.

[0081] This design is not only compact and easy to operate, but also enables rapid and precise adjustment of the position of the retainer 101 (or cleaning rack 104), improving the adaptability and flexibility of the equipment. Furthermore, the use of a motor 10505 as a secondary drive device makes the adjustment process smoother and more reliable, reducing the difficulty and error of manual operation. In addition, the adjustment mechanism 105 is easy to maintain and has low cost, making it suitable for various applications requiring precise position adjustment.

[0082] In this invention, a side frame 107 is mounted on one side of the retainer 101, and an electric slip ring 108 is mounted on the inner side of the side frame 107, achieving stable transmission of electrical signals. The rotating end of the electric slip ring 108 is electrically connected to the second driving device and the compaction sensor 103 via wires. This design not only ensures signal continuity during the rotation process but also improves the working efficiency and stability of the equipment. Furthermore, this structure is compact, easy to install, and effectively reduces the overall complexity and maintenance costs of the equipment.

[0083] In this invention, a limiting post 110 is installed at the top of the chassis 100. This design not only enhances the overall stability of the chassis 100 but also facilitates subsequent installation and configuration. The presence of the limiting post 110 ensures that the internal components of the chassis 100 will not shift due to vibration or external forces during operation, thereby guaranteeing the normal operation and long service life of the equipment. A counterweight block 111 is fitted on the outer side of the limiting post 110. This counterweight design, on the one hand, balances the center of gravity of the chassis 100, making the chassis 100 more stable during placement and use, reducing the risk of tipping or shaking; on the other hand, the counterweight block 111 also increases the overall weight of the chassis 100, further improving the chassis 100's wind pressure resistance and shock resistance, enabling it to maintain excellent stability and reliability in various complex environments.

[0084] In summary, this utility model, through the combined design of the limiting post 110 and the counterweight block 111, significantly improves the structural stability and operational safety of the chassis 100, providing a strong guarantee for the normal operation of the equipment.

[0085] In this invention, an energy storage battery, preferably a lithium battery, is installed inside the chassis 100. This type of battery has advantages such as high energy density, long lifespan, and environmental friendliness, providing continuous and stable power support for the device. A charging interface 113 for charging the energy storage battery is installed at the top of the chassis 100. This facilitates quick and convenient charging of the energy storage battery, improving the ease of use and practicality of the device.

[0086] In summary, the advantages of this utility model lie in providing long-lasting and stable power support and convenient charging methods, which effectively improves user experience and device performance.

[0087] In this invention, a control panel 116 is provided on one end face of the chassis 100. This design allows users to operate and monitor the equipment intuitively, greatly improving the ease of use and user experience. The control panel 116 has a reasonable layout and clear functions, allowing users to quickly familiarize themselves with and master its operation, thereby improving work efficiency. A signal transceiver 112 is provided on the top of the chassis 100. This layout not only facilitates stable signal transmission but also avoids the possibility of signal interference from other components inside the chassis 100. The reasonable placement of the signal transceiver 112 ensures the communication quality between the equipment and the outside world, further improving the reliability and stability of the equipment.

[0088] In this invention, the chassis 100 is equipped with a handle 109, a design that greatly facilitates the handling and movement of the chassis 100. Whether adjusting the position of the chassis 100 or moving it from one place to another, the user can easily lift and move the chassis 100 using the handle 109, thus saving physical strength and time and improving work efficiency. A towing seat 114 is provided on the other side of the chassis 100. This design allows the chassis 100 to be connected and towed by other equipment or vehicles. For example, when the chassis 100 needs to be moved to a distant location or frequently moved between different locations, the user can connect the chassis 100 to a handcart, forklift, or other transport vehicle using the towing seat 114, thereby achieving long-distance, fast, and stable movement of the chassis 100, further improving work efficiency and convenience.

[0089] In this utility model, casters 106 are installed on both sides of the bottom end of the chassis 100, which gives the device good mobility, facilitates rapid transfer between different construction areas, and improves the device's flexibility and work efficiency.

[0090] like Figure 6 As shown, on the other hand, this utility model also provides a monitoring method for the above-mentioned real-time compaction monitoring device during asphalt pavement construction, including the following steps:

[0091] S1, Start monitoring: Press the start button and the compaction sensor 103 starts working. As the roller 102 rolls on the asphalt pavement, the compaction sensor 103 detects the compaction of the pavement in real time and transmits the detected signal to the processing system.

[0092] S2, Data transmission: The processing system processes and analyzes the signal transmitted from the compaction sensor 103, converts it into compaction data, and sends the processed data to the monitoring center in real time. On the other hand, it displays the current compaction value of the asphalt pavement in real time, so that on-site construction personnel can check it at any time.

[0093] S3, Preliminary cleaning: Start the adjustment mechanism 105 to perform preliminary cleaning on the outer surface of the compaction sensor 103;

[0094] S4, Deep cleaning: Activate the deep cleaning mechanism 115 to perform deep cleaning on the surface of the compaction sensor 103;

[0095] S5, Stop monitoring: When the asphalt pavement compaction operation is completed or the predetermined monitoring time is reached, the compaction sensor 103 stops working and the device stops collecting and transmitting compaction data.

[0096] Based on the monitoring device provided by this utility model, the monitoring method is as follows:

[0097] S1, Start monitoring: Press the start button on the control panel 116, and the compaction sensor 103 (103) starts to work. As the roller 102 rolls on the asphalt pavement, the compaction sensor 103 detects the compaction of the pavement in real time and transmits the detected signal to the processing system inside the control panel 116 through the electric slip ring 108.

[0098] S2, Data transmission: The processing system inside the control panel 116 processes and analyzes the signal transmitted from the compaction sensor 103 and converts it into compaction data. The processed data is sent to the monitoring center or other related equipment in real time through the signal transceiver 112 (112). On the other hand, the current compaction value of the asphalt pavement is displayed in real time on the display screen of the control panel 116, which is convenient for on-site construction personnel to check at any time.

[0099] S3, Cleaning rack 104 cleaning: During the monitoring process, if it is found that there are many impurities on the surface of the compaction sensor 103 that affect the detection accuracy, the motor 10505 can be started through the control panel 116, so that the motor 10505 drives the bidirectional threaded rod 10501 to rotate. The movable block 10502 on the bidirectional threaded rod 10501 moves in opposite directions under the action of the thread, and pushes the push rod 10504 to slide in the sliding mouth 10202 through the connecting rod 10503, thereby driving the cleaning rack 104 to slide along the outside of the compaction sensor 103 to perform preliminary cleaning on the surface of the compaction sensor 103, and at the same time push the debris out of the groove 10201;

[0100] S4, Sensor Cleaning: Control the extension and retraction of the electric telescopic rod 11505 on the control panel 116. The output end of the electric telescopic rod 11505 pushes the moving frame 11501, causing the slider 11503 to slide on the slide rail 11504. The cleaning brush 11502 on one side of the moving frame 11501 contacts the compaction sensor 103 on the outside of the roller body 102. When the roller body 102 rotates, the surface of the compaction sensor 103 can be cleaned more thoroughly.

[0101] S5, Stop monitoring: When the asphalt pavement compaction operation is completed or the predetermined monitoring time is reached, press the stop button on the control panel 116, the compaction sensor 103 stops working, and the device stops collecting and transmitting compaction data.

[0102] This monitoring method has the following advantages:

[0103] (1) Real-time monitoring and data analysis: The compaction status of the road surface is detected in real time by the compaction sensor 103, and the signal is transmitted to the processing system inside the control panel 116 to realize real-time monitoring. The processing system processes and analyzes the signal, converts it into compaction data, and provides accurate road surface compaction information.

[0104] (2) Real-time data transmission and display: The processed compaction data is sent to the monitoring center or other related equipment in real time through the signal transceiver 112. At the same time, the current compaction value of the asphalt pavement is displayed on the screen of the control panel 116 in real time, which is convenient for on-site construction personnel to check at any time and improve construction efficiency and quality.

[0105] (3) Automated cleaning function: If impurities are found on the surface of the compaction sensor 103 during the monitoring process, affecting the detection accuracy, the cleaning mechanism can be started through the control panel 116, including cleaning of the cleaning rack 104 and cleaning of the sensor, to perform preliminary and more thorough cleaning of the surface of the compaction sensor 103, ensuring the accuracy of the monitoring data.

[0106] (4) Easy to operate: The monitoring and cleaning operations can be started, stopped and cleaned through the control panel 116. The operation is simple and easy to master.

[0107] (5) Strong applicability: This monitoring method is applicable to different types of asphalt pavement compaction operations and has wide applicability.

[0108] The above description is merely a preferred embodiment of this utility model. However, the scope of protection of this utility model is not limited thereto; any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
