Description

Technical Field

[0001] The invention relates to the technical field of slope maintenance, in particular to an intelligent maintenance device for excavated slopes in highway engineering. Background Art

[0002] In modern highway projects, ensuring the stability of slopes and carrying out effective maintenance are key measures to maintain road safety and extend their service life. Traditional slope maintenance methods mainly rely on manual operation and fixed pipe sprinkler facilities. However, these traditional methods have many limitations in technology and implementation.

[0003] First, when installing a shaped pipe irrigation system, a large number of pipes need to be laid, which not only increases the difficulty and cost of the project, but may also have an adverse effect on the geological conditions of the slope. For areas with rugged terrain or irregular slope contours, it is difficult for the system to achieve the expected irrigation coverage effect. In addition, in the face of emergencies such as geological changes or slope sliding, the shaped pipe system is easily damaged and is quite inconvenient to repair.

[0004] Secondly, the adjustable nature of the fixed pipe irrigation system is poor. Due to its fixed installation position, the scope and direction of irrigation are limited, and it is difficult to flexibly adjust the irrigation area and water volume according to specific conditions. When the soil moisture, climate conditions, plant species and other conditions of the slope change, the water output of the pipe irrigation is usually unable to make adaptive adjustments in time. This inflexible irrigation method may lead to a waste of water resources, or affect plant growth due to insufficient water supply, thereby hindering the restoration of the slope ecology.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, an intelligent maintenance device for excavated slopes of highway engineering comprises a power device 1 arranged at the top of the slope and a driven support device 2 arranged at the foot of the slope. A sprinkler device 3 is installed between the power device 1 and the driven support device 2. The sprinkler device 3 is located above the slope surface. The power device 1 drives the sprinkler device 3 to move along the extension direction of the slope surface, so as to achieve covering and sprinkler irrigation on the slope surface with continuous movement. The power device 1 includes at least one track 101, a body 102, a running mechanism 103, a water tank 104 and a water pump 105. The track 101 is arranged on the top of the slope along the extension direction thereof. The side of the body 102 is slidably arranged on the track 101. The running mechanism 103 is installed at the bottom of the body 102 to drive the body 102 to move along the track 101. The water tank 104 and the water pump 105 are respectively installed on the body 102, and the water inlet end of the water pump 105 is communicated with the water tank 104. The sprinkler irrigation device 3 includes a bracket 201, a water diversion pipe 202 and a plurality of nozzles 203. The two ends of the bracket 201 are respectively connected to the front end of the body 102 and the driven support device 2. The water diversion pipe 202 is installed on the bracket 201 along its extension direction. The water outlet end of the water pump 105 is connected to the water diversion pipe 202. A plurality of nozzles 203 are arranged on the water diversion pipe 202. The water pump 105 pumps the water stored in the water tank 104 into the water diversion pipe 202 and sprays it out from the nozzle 203.

[0023] See also Figure 2 , Figure 3 and Figure 5 As shown, the driven support device 2 includes at least one guide rail 204 and a base, a guide path 206 is provided at the foot of the slope along the extending direction of the slope surface, the guide rail 204 is installed on the side wall of the guide path 206, the side of the base is slidably installed on the guide rail 204, one end of the bracket 201 is fixedly installed on the base, and the base moves synchronously with the movement of the power device 1 under the drive of the bracket 201, the travel mechanism 103 includes a pair of driving wheels 219 and a motor, two tracks 101 are arranged on the top of the slope, guide frames 220 are installed at both ends of the body 102, and the guide frames 220 on both sides are respectively slidably connected to the two tracks 101, the driving wheel 219 is installed at the bottom of the body 102 and is located between the two tracks 101, and the motor is installed inside the body 102 and is connected to the driving wheel 219 in a transmission manner; By setting two tracks 101 and allowing the front and rear ends of the body 102 to slide and snap onto the tracks 101 respectively, it not only plays a guiding role but also helps to fix the bottom of the body 102. The two tracks 101 can prevent the body 102 from tipping over during movement due to the weight of the bracket 201; at the same time, the base can effectively support the bracket 201, thereby ensuring the stability of the body 102 during movement.

[0024] See also Figure 2 and Fig. 9 As shown, a plurality of auxiliary sprinkler mechanisms 207 are movably mounted on the bracket 201, and the auxiliary sprinkler mechanisms 207 include a bracket 208, an auxiliary sprinkler head 209, a motor 210 and a driving wheel 211. The left and right end surfaces of the bracket 201 are provided with guide grooves 212 along the extension direction. The bracket 208 is slidably mounted on the surface of the bracket 201, and the left and right inner end surfaces of the bracket 208 are rotatably mounted with guide wheels 213, and the guide wheels 213 on both sides are respectively located in the guide grooves 212 on the same side and move; the driving wheel 211 is rotatably mounted on the top of the bracket 208 and the driving wheel 211 abuts against the top surface of the bracket 201, the motor 210 is mounted on the top of the bracket 208 and is transmission-connected with the driving wheel 211, the auxiliary sprinkler head 209 is mounted on the left end of the bracket 208, and the water inlet end of the auxiliary sprinkler head 209 is communicated with the water diversion pipe 202 through a hose 214; The motor 210 drives the driving wheel 211 to rotate, so that the bracket 208 can move forward and backward on the bracket 201. Since the sprinkler head 203 is evenly covered for irrigation, the spraying amount of each area on the slope is almost the same. However, if the vegetation in a certain area needs more water, the bracket 208 can be moved above the area and the hose 214 can be dragged. The water flow in the water pipe 202 is sprayed from the auxiliary sprinkler head 209 of the bracket 208 to the area through the hose 214, thereby increasing the spraying amount of the water-deficient area. At the same time, targeted irrigation will not affect the spraying amount of other normal areas, and will not cause excessive irrigation of other areas.

[0025] See also Figure 7 As shown, a plurality of guide columns 215 are fixedly installed at the bottom of the left end of the bracket 208, and a positioning seat 216 is slidably installed between each guide column 215. The auxiliary sprinkler head 209 is installed at the bottom of the positioning seat 216. A pneumatic cylinder 217 is fixedly installed on the side of the bracket 208, and the piston rod of the pneumatic cylinder 217 is connected to the top of the positioning seat 216 to drive the positioning seat 216 to move up and down; The distance between the auxiliary sprinkler head 209 and the slope surface is positively correlated with its spraying range. When the distance between the auxiliary sprinkler head 209 and the slope surface is large, the water flow has more space to spread, thereby expanding the spraying range; conversely, when the distance is small, the spraying range will be reduced. Moreover, the smaller the spraying range, the higher the concentration of the water flow. Therefore, according to the specific conditions of the area to be compensated, the spraying range and the concentrated spraying amount of the water flow can be flexibly adjusted by means of the intelligent lifting of the auxiliary sprinkler head 209.

[0026] At the same time, appropriately reducing the distance between the auxiliary sprinkler head 209 and the slope surface can reduce the degree of wind interference on the sprayed water flow, ensure that the water flow accurately falls on the predetermined irrigation area, and effectively prevent unnecessary loss of water resources.

[0027] See also Figure 2 , Figure 4 and Fig. 9 As shown, an auxiliary sprinkler mechanism 207 is installed between two adjacent sprinklers 203, and a bracket 208 moves in the area between the two adjacent sprinklers 203. The sprinkler 203 is arranged at the top of the water diversion pipe 202 and extends through the sprinkler 203 to the top surface of the bracket 201, and its water spraying direction is set upward; the auxiliary sprinkler head 209 is installed at the bottom of the left end of the bracket 208, and its water spraying direction is set downward. A plurality of sensors 218 for monitoring the state of the slope are evenly distributed along the extension direction at the right end of the bracket 201. A first solenoid valve is installed at the connection between each sprinkler 203 and the water diversion pipe 202, and a second solenoid valve is installed on each hose 214. The first solenoid valve, the second solenoid valve and the sensor 218 are all electrically connected to the processor; The sprinkler head 203 can spray the water pumped into the water pipe 202 into the air, so that the water is dispersed into fine water droplets and then falls onto the slope surface, thereby achieving uniform and extensive irrigation of the plants and soil on the slope surface. The auxiliary sprinkler head 209 is in a downward posture, and the water flow can be directly sprayed onto the slope. Although the sprinkler irrigation range is relatively small, the water flow is large, which can quickly make the specific area reach the required irrigation water volume, effectively reducing the time required for compensatory sprinkler irrigation, and does not affect the mobile sprinkler irrigation work of the bracket 201; the slope environment in the moving direction of the bracket 201 is detected by the sensor 218 (such as vision, humidity, temperature, etc.), and uploaded to the background analysis, and the irrigation area and irrigation amount are adjusted according to factors such as vegetation type and soil state. The processor sends a signal to the first solenoid valve, the second solenoid valve and the motor 210. In the normal sprinkler irrigation area, the first solenoid valve is opened and the second solenoid valve is closed, and the sprinkler head 203 performs uniform coverage irrigation; if most of the water is sufficient and only a small area needs to be irrigated, the first solenoid valve is closed, and after the bracket 208 moves to the area, the corresponding second solenoid valve is opened to irrigate it; in the water-deficient area, the first solenoid valve and the second solenoid valve are opened, and the bracket 208 is continuously moved to the extremely water-deficient area for compensatory irrigation; Sensor 218 can sense environmental changes in real time. Based on this real-time information, it can make intelligent irrigation decisions and automatically adjust the spraying area, spraying amount and frequency to ensure that the slope is always in an ideal humidity state. At the same time, by uploading real-time monitoring data to the cloud, it can monitor the changes in the slope for a long time, which is convenient for managers to formulate scientific maintenance plans.

[0028] See also Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig.10 As shown, it also includes a plurality of energy-continuing cabinets 4 and electric wires 401 and water pipes 402 arranged on the top of the slope. The electric wires 401 and water pipes 402 are arranged parallel to the track 101 and are located on the rear side of the track 101. Each energy-continuing cabinet 4 is arranged on it at equal intervals along the extension direction of the top of the slope. A water supply pipe 403 and a charging socket are installed on the front end surface of the energy-continuing cabinet 4. The water supply pipe 403 is connected to the water pipe 402 and a water outlet valve is installed thereon. The charging socket 404 is electrically connected to the electric wire 401. A movable base 410 is installed at the rear end of the body 102. A screw rod 408 and a plurality of slide rails 409 are installed on the rear bottom surface of the body 102, the bottom end of the base 410 is slidably installed on the slide rail 409, and the middle part of the bottom end of the base 410 is threadedly connected to the surface of the screw rod 408, the screw rod 408 is driven to rotate by the second motor, the water storage tank 104 is installed on the base 410, and the base 410 is also installed with an energy storage battery 405 for supplying power to various mechanisms, the water pump 105 is connected to the water storage tank 104 through a telescopic pipe, and a water inlet 406 connected to the interior of the water storage tank 104 is installed on the top of the rear end of the water storage tank 104, and a charging connector 407 is installed at the rear end of the energy storage battery 405, the water inlet 406 matches the water supply pipe 403 and is located at the same height, the charging connector 407 matches the charging socket and is located at the same height, and the base 410 drives the water storage tank 104 and the energy storage battery 405 to move backwards so as to connect with the energy-renewing cabinet 4; When the water in the water tank 104 is used up or the power of the energy storage battery 405 is insufficient, it will automatically locate to the nearest energy-renewing cabinet 4. At this time, the driving wheel 219 will drive the bracket 201 to move to the front of the energy-renewing cabinet 4. Then, the second motor starts, pushing the base 410 to move backward, so that the water tank 104 and the energy storage battery 405 carried on the base 410 move backward together. In this process, the charging connector 404 of the energy storage battery 405 will be accurately inserted into the charging socket of the energy-renewing cabinet 4 to start the charging operation; at the same time, the water supply pipe 403 will be inserted into the water inlet 406 of the water tank 104, and the water outlet valve will be opened to introduce the water flow in the water pipe 402 into the water tank 104 for water replenishment. After the water replenishment or charging is completed, the base 410 returns to the initial position, and the device can continue to perform the irrigation task, thereby realizing the intelligent automatic endurance function, which can meet the needs of long-distance irrigation of the slope.
