Description

Technical Field

[0001] This application relates to the field of slope maintenance equipment, and more specifically, to a spray water truck for dam slope maintenance. Background Technology

[0002] Dam slopes are typically constructed of concrete. To prevent cracking, curing is necessary after pouring, artificially creating specific humidity and temperature conditions to allow the freshly poured concrete to harden and gain strength normally or more quickly. During curing, water is sprayed to maintain the concrete's moisture. After watering, a membrane is applied to the slope to ensure a tight bond between the curing film and the concrete surface, promoting hydration and playing a significant role in preventing cracking and retaining moisture. However, because dams usually have a slope, the water sprayed may not fully wet the concrete above before flowing down the slope due to gravity. When the membrane is subsequently applied, the water has already run off the upper slope, affecting the curing effect.

[0003] Therefore, a spray truck for dam slope maintenance is needed to solve the above problems. Summary of the Invention

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a spray sprinkler truck for dam slope maintenance, comprising: a traveling vehicle with a boom mounted on it, a sprinkler arm mounted at one end of the boom, rollers rotatably mounted at both ends of the sprinkler arm, a sprinkler cylinder rotatably mounted on the sprinkler arm, a plurality of evenly distributed atomizing nozzles mounted on the sprinkler cylinder, and an adjustment assembly mounted on the sprinkler cylinder for adjusting the spray direction of the sprinkler cylinder. The adjustment assembly includes: symmetrically arranged mounting side plates fixedly connected to the sprinkler cylinder, atomizing nozzles rotatably mounted between the two mounting side plates, a side box fixedly connected to the sprinkler cylinder on one side of the atomizing nozzles, and a shaft head fixedly mounted on the atomizing nozzles for rotatable cooperation with the mounting side plates, one end of the shaft head extending into the side box, and a fixed... A fixed connection is provided with a mating wheel located inside the side box. A rack that slidably engages with the mating wheel is also located inside the side box. A connecting hose connects the atomizing nozzle to the sprinkler cylinder. An adjusting motor is fixedly installed on the sprinkler arm. A gear is fixedly connected to the power output end of the adjusting motor. An outer gear ring is fixedly connected to the outer wall of the sprinkler cylinder. The gear engages with the outer gear ring, and the adjusting motor drives the sprinkler cylinder to rotate around its own axis. A connecting box is fixedly installed on the sprinkler arm. The connecting box has an arc-shaped surface that fits against the outer wall of the sprinkler cylinder. A track groove is opened on the connecting box on the arc-shaped surface. A water inlet is opened on the outer wall of the sprinkler cylinder. The track groove extends along the movement trajectory of the water inlet. A water tank and a water pump are installed inside the sprinkler arm. A water delivery hose is connected to the output end of the water pump. One end of the water delivery hose is connected to the connecting box. A wind direction sensor is fixedly installed on the sprinkler arm.

[0006] Furthermore, a moving ring is slidably mounted on the outside of the sprinkler arm, and an adjusting telescopic rod is fixedly mounted on the sprinkler arm. The telescopic rod end of the adjusting telescopic rod is fixedly connected to the moving ring, and a coaxially mounted slip ring is slidably mounted on the moving ring. One end of the rack is fixedly connected to the slip ring.

[0007] Furthermore, a membrane roller located in front of the sprinkler cylinder is rotatably mounted on the sprinkler arm, and a maintenance film is wound on the membrane roller. A guide roller located behind the sprinkler cylinder is also rotatably mounted on the sprinkler arm. The maintenance film on the membrane roller passes through the upper side of the sprinkler cylinder and is guided by the guide roller. The membrane roller and the guide roller prevent the film from contacting the upper side of the sprinkler cylinder. A film covering assembly is also provided on the sprinkler arm, which attaches the maintenance film to the slope.

[0008] Furthermore, the film covering assembly includes: a fixed shaft fixedly mounted on the sprinkler arm; two swing arms rotatably mounted on the fixed shaft; a tensioning cylinder and a pressure cylinder rotatably mounted between the two swing arms; a rotating ring rotatably mounted on the fixed shaft; a torsion spring connecting the rotating ring and one of the swing arms; an L-shaped rod fixedly connected to the rotating ring; and an abutting post fixedly connected to the torsion spring, which abuts against the L-shaped rod. The L-shaped rod has an inclined end, and the abutting post contacts the inclined end of the L-shaped rod. The movement of the rotating ring causes the L-shaped rod to push the abutting post, thereby driving the rotating ring to rotate.

[0009] Furthermore, an air pump is fixedly installed on the sprinkler arm. The air pump's outlet end is connected to a branch air pipe. One end of the branch air pipe has two connecting ends, which are respectively connected to the tensioning cylinder and the pressure cylinder. The tensioning cylinder is provided with multiple sets of evenly distributed inclined pipes. The inclined pipes form air outlets on the outer surface of the tensioning cylinder that communicate with the inner cavity of the tensioning cylinder. The air outlet direction forms a first angle with the axis of the tensioning cylinder.

[0010] Furthermore, the pressure cylinder has multiple sets of through holes on its side wall and multiple sets of annular covers inside the pressure cylinder, which cover the through holes. A sliding head is slidably mounted on the annular cover, and a vent hole is opened on the sliding head. Gas inside the pressure cylinder enters the annular cover through the vent hole and exits through the through hole. The upper end of the pressure cylinder is designated as the first end. A connector is fixed on the inner wall of the pressure cylinder near the first end. A movable rod is mounted on the connector, with one end of which is hinged to the connector. A hinge ear is fixedly mounted on the upper end of the sliding head, which is hinged to the movable rod. A telescopic head is slidably mounted inside the pressure cylinder near the second end. The telescopic head has a sliding groove. An abutment block is fixedly connected to one end of the movable rod and is embedded in the sliding groove. A sliding shaft that slides with the pressure cylinder is fixedly mounted on the telescopic head. A spring is connected between the sliding shaft and the pressure cylinder. The two ends of the spring are fixedly connected to the sliding shaft and the pressure cylinder, respectively. A follower cover is fixedly mounted on the telescopic head, and the follower cover is located at the connection between the branch gas pipe and the pressure cylinder.

[0011] Furthermore, a first support cylinder is installed on the traveling vehicle. One end of the first support cylinder is hinged to the boom. The boom is deflected by the extension and retraction of the first support cylinder. An installation head is installed on the sprinkler arm. The installation head is connected to one end of the boom through a second hinge joint. A second support cylinder is installed on the boom. One end of the second support cylinder is hinged to a first hinge joint fixed on the boom. The other end of the second support cylinder is hinged to the installation head through a second hinge joint. The sprinkler arm is deflected by the extension and retraction of the second support cylinder. An tilt sensor is installed on the sprinkler arm.

[0012] Furthermore, a control center is integrated into the vehicle.

[0013] The beneficial effects of this application are as follows: 1. By adjusting the motor and sprinkler cylinder, it is found that in windy weather, the water sprayed is tilted by the wind and cannot fall vertically onto the slope, affecting the maintenance effect. A wind direction sensor is installed on the sprinkler arm, which directly obtains the wind direction and strength. This sensor then controls the motor output power, driving the gears to rotate, which in turn drives the sprinkler cylinder to deflect at a certain angle. This tilts the sprinkler cylinder, counteracting the wind force and ensuring that the water falls vertically onto the slope.

[0014] 2. By using the tilt sensor and adjusting the telescopic rod, when maintaining an inclined slope, the tilt sensor detects the tilt angle and controls the extension of the telescopic rod, which in turn drives the motion ring to move. This causes the slip ring to drive the rack, which in turn causes the sprinkler to deflect through the rack and the mating wheel, tilting the sprinkler upward so that the water falls vertically onto the slope.

[0015] 3. With the tensioning cylinder and pressure cylinder in place, when covering the film, the air pump is started to introduce air into the tensioning cylinder and pressure cylinder. The air in the tensioning cylinder is discharged through the inclined pipe to form an airflow that blows out in all directions, thereby tensioning the film. At the same time, because the inclined pipe is set at an angle, the direction of the airflow blown out by the inclined pipe is equal to the angle between the slope and the first angle. The first angle is set to a small acute angle, so that the airflow blown out by the inclined pipe makes the water on the slope overcome gravity and prevent the water from flowing down directly. This ensures that water remains at the upper part of the slope when covering the film later, thus ensuring the curing effect. Attached Figure Description

[0024] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Reference Figure 1-13 A sprayer truck for dam slope maintenance includes: a traveling vehicle 10, a boom 11, a spraying arm 12, a first support cylinder 13, a second support cylinder 14, a first hinge joint 15, a mounting head 16, and a second hinge joint 17. The traveling vehicle 10 has a rotatable base. One end of the boom 11 is rotatably mounted on the base, and the first support cylinder 13 is mounted on the base, with one end connected to the middle section of the boom 11. The pitch angle of the boom 11 is adjusted by extending and retracting the first support cylinder 13, thereby maintaining slopes at different heights. The spraying arm 12 is mounted on one end of the boom 11, and the mounting head 16 is fixedly mounted at the middle section of the spraying arm 12. The mounting head 16 is connected to one end of the boom 11 via a mounting pin 19, allowing the spraying arm 12 to deflect, thus maintaining slopes at different angles. A first hinge joint 15 is fixedly installed on the boom 11. One end of a second support cylinder 14 is hinged to the first hinge joint 15. A second hinge joint 17 is installed on the mounting head 16, and one end of the second support cylinder 14 is hinged to the second hinge joint 17. The tilt angle of the sprinkler arm 12 is adjusted by extending and retracting the second support cylinder 14. During maintenance, the sprinkler arm 12 is placed against the slope, and the traveling vehicle 10 moves along the slope to maintain the dam slope. Two rollers 18 are rotatably installed on the sprinkler arm 12. During maintenance, the rollers 18 roll along the slope surface.

[0026] A water spray cylinder 22 is rotatably mounted on the water spray arm 12. Multiple atomizing nozzles 34 are evenly distributed on the water spray cylinder 22. A water tank and water pump (not shown in the figure, but refer to the water tank and water pump in existing water trucks) are installed on the traveling vehicle 10. The water pump is connected to the water tank and draws water from the tank. A water delivery hose 27 is connected to the outlet of the water pump. A connecting box 28 connected to the water delivery hose 27 is fixedly installed on the water spray arm 12. Water is drawn into the connecting box 28 through the water pump and the water delivery hose 27. The connecting box 28 has an arc-shaped surface that fits against the outer wall of the water spray cylinder 22. A track groove 29 is formed on the arc-shaped surface. A water inlet hole 30 is provided on the outer surface of the water spray cylinder 22. The track groove 29 extends along the track of the shaft end 39. An adjusting motor 24 is fixedly installed on the sprinkler arm 12. A gear 25 is fixedly connected to the power output end of the adjusting motor 24. An outer gear ring 23 is fixedly connected to the outer wall of the sprinkler cylinder 22. The gear 25 and the outer gear ring 23 cooperate to drive the sprinkler cylinder 22 to rotate around its own axis through the adjusting motor 24.

[0027] During maintenance, the traveling vehicle 10 moves along the slope, driving the water spraying arm 12 and the water spraying cylinder 22 to move along the slope. At this time, the water pump is started to pump water into the water spraying cylinder 22 and spray it onto the slope through the atomizing nozzle 34 to maintain the slope.

[0028] When strong winds occur, the water sprayed is blown at an angle and cannot fall vertically onto the slope, affecting the maintenance effect. A wind direction sensor 32 is installed on the sprinkler arm 12. The wind direction sensor 32 can directly obtain the wind direction and wind force, and then control the motor 24 to output power, drive the gear 25 to rotate, and then drive the sprinkler cylinder 22 to deflect through the outer gear ring 23. This deflection of the sprinkler cylinder 22 at a certain angle makes the sprinkler cylinder 22 spray water at an angle, counteracting the wind force and ensuring that the sprayed water falls vertically onto the slope.

[0029] When the slope is inclined, even if the water spraying direction of the sprinkler 22 is directly facing the slope, it will still deviate under the action of gravity. Therefore, the following solution is adopted. Symmetrically arranged mounting side plates 33 are fixedly connected to the sprinkler 22. The atomizing nozzle 34 is rotatably mounted between the two mounting side plates 33. A side box 36 located on one side of the atomizing nozzle 34 is fixedly connected to the sprinkler 22. A shaft head 39 that rotatably engages with the mounting side plates 33 is fixedly installed on the atomizing nozzle 34. One end of the shaft head 39 extends into the side box 36. A mating wheel 38 located inside the side box 36 is fixedly connected to the shaft head 39. A rack 37 that mates with the mating wheel 38 is slidably arranged inside the side box 36. A connecting hose 35 connects the atomizing nozzle 34 and the sprinkler 22. A moving ring 40 is slidably mounted on the outside of the sprinkler arm 12. An adjusting telescopic rod 41 is fixedly mounted on the sprinkler arm 12, with its telescopic end fixedly connected to the moving ring 40. A coaxially mounted slip ring 42 is slidably mounted on the moving ring 40, and one end of a rack 37 is fixedly connected to the slip ring 42. An inclination sensor 20 is installed on the sprinkler arm 12 to detect the inclination angle of the sprinkler arm 12. When maintaining an inclined slope, the inclination sensor 20 detects the inclination angle and controls the extending of the adjusting telescopic rod 41, which in turn drives the moving ring 40 to move. This causes the slip ring 42 to drive the rack 37 to move, and through the rack 37 and the mating wheel 38, the sprinkler cylinder 22 deflects, tilting the sprinkler cylinder 22 upwards so that the water falls vertically onto the slope.

[0030] A membrane roller 21 is rotatably mounted on the sprinkler arm 12, located in front of the sprinkler cylinder 22 (in the direction of travel of the vehicle 10). A curing film is wound on the membrane roller 21. A guide roller 43 is also rotatably mounted on the sprinkler arm 12, located behind the sprinkler cylinder 22. The curing film on the membrane roller 21 passes through the upper side of the sprinkler cylinder 22 and is guided by the guide roller 43. The membrane roller 21 and the guide roller 43 prevent the film from contacting the upper side of the sprinkler cylinder 22. A film covering assembly is also provided on the sprinkler arm 12, which attaches the curing film to the slope.

[0031] During maintenance, water is sprayed onto the slope using atomizing nozzles 34, and then the slope is covered with a membrane using a membrane covering assembly.

[0032] The mulching assembly includes: a fixed shaft 26 fixedly mounted on the sprinkler arm 12; two swing arms 46 rotatably mounted on the fixed shaft 26; a tensioning cylinder 44 and a pressure cylinder 45 rotatably mounted between the two swing arms 46; the pressure cylinder 45 being located at the end of the swing arm 46; a rotating ring 62 rotatably mounted on the fixed shaft 26; a torsion spring 63 connecting the rotating ring 62 and one of the swing arms 46; an L-shaped rod 61 fixedly connected to a moving ring 40; and an abutment post 31 fixedly connected to the torsion spring 63, abutting against the L-shaped rod 61. The L-shaped rod 61 has an inclined end, and the abutment post 31 contacts the inclined end of the L-shaped rod 61. Movement of the moving ring 40 causes the L-shaped rod 61 to push the abutment post 31, thereby driving the rotating ring 62 to rotate. It should be noted that the swing arm 46 has an initial position on the fixed shaft 26, in which the angle between the swing arm 46 and the slope is small. When the moving ring 40 moves, it drives the rotating ring 62 to rotate via the L-shaped rod 61. The torsion spring 63 then twists, causing the swing arm 46 to rotate, thus increasing the angle between the swing arm 46 and the slope. During maintenance, the pressure cylinder 45 adheres the maintenance film to the slope. When the slope angle is large, adjusting the telescopic rod 41 will drive the moving ring 40 to move, which in turn causes the torsion spring 63 to twist, causing the pressure cylinder 45 to adhere tightly to the slope, increasing the adhesion of the film and preventing it from slipping off due to insufficient adhesion.

[0033] In one embodiment, to prevent the protective film from loosening and causing wrinkles, the following solution is adopted. An air pump 47 is fixedly installed on the sprinkler arm 12. The air outlet of the air pump 47 is connected to a branch air pipe 48. One end of the branch air pipe 48 has two connecting ends, which are respectively connected to the tensioning cylinder 44 and the pressure cylinder 45. Multiple sets of evenly distributed inclined pipes 60 are provided inside the tensioning cylinder 44. The inclined pipes 60 form air outlets on the outer surface of the tensioning cylinder 44 that communicate with the inner cavity of the tensioning cylinder 44. The air outlet direction forms a first angle with the axis of the tensioning cylinder 44. Multiple sets of through holes are also provided on the side wall of the pressure cylinder 45. When covering the film, the air pump 47 is activated, thereby introducing air into the tensioning cylinder 44 and the pressure cylinder 45. The air inside the tensioning cylinder 44 is discharged through the inclined pipes 60, forming an airflow that blows outwards, thereby tensioning the film. Simultaneously, the airflow introduced into the pressure cylinder 45 is blown out through the through hole, adhering the film to the slope surface and preventing the film from failing to adhere due to slope depressions. Furthermore, because the inclined pipe 60 is tilted, the angle between the airflow direction and the slope surface is equal to the first angle, which is set to a small acute angle. This allows the airflow blowing through the inclined pipe 60 to overcome gravity on the slope surface, preventing water from flowing directly downhill. This ensures that water remains at the upper end of the slope surface during subsequent film covering, guaranteeing the curing effect.

[0034] Multiple annular covers 50 are provided inside the pressure cylinder 45, covering the through holes. A sliding head 53 is slidably mounted on the annular cover 50, and a vent hole 54 is provided on the sliding head 53. Gas inside the pressure cylinder 45 enters the annular cover 50 through the vent hole 54 and exits through the through hole. It should be noted that the airflow rate can be adjusted by adjusting the size of the area of ​​the vent hole 54 exposed above the annular cover 50. The upper end of the pressure cylinder 45 is designated as the first end. A connector 52 is fixed on the inner wall of the pressure cylinder 45 near the first end. A movable rod 51 is provided on the connector 52, with one end hinged to the connector 52. A hinge ear is fixedly mounted on the upper end of the sliding head 53, hinged to the movable rod 51. A telescopic head 56 is slidably mounted inside the pressure cylinder 45 near the second end of the pressure cylinder 45. The telescopic head 56 is provided with a sliding groove. An abutment block 57 is fixedly connected to one end of the movable rod 51, and the abutment block 57 is embedded in the sliding groove. A sliding shaft 55 is fixedly installed on the telescopic head 56, which slides in cooperation with the pressure cylinder 45. A spring 59 is connected between the sliding shaft 55 and the pressure cylinder 45. The two ends of the spring 59 are fixedly connected to the sliding shaft 55 and the pressure cylinder 45, respectively. A follower cover 58 is fixedly installed on the telescopic head 56, which is located at the connection between the branch air pipe 48 and the pressure cylinder 45. When the slope angle is too large, the output power of the air pump 47 is increased, so that the airflow blows the follower cover 58 and drives the telescopic head 56 to move, which compresses the spring 59, thereby causing the abutment block 57 and the movable rod 51 to deflect, which drives the sliding head 53 to move, making the area of ​​the vent 54 exposed above the annular cover 50 larger, increasing the airflow discharged from the vent 49, so that the airflow blows the film tightly against the slope, improving the adhesion and preventing the film from slipping off. Furthermore, because the exposed area of ​​the vent 54 near the lower end is relatively large, the airflow of the vent 49 in the lower part of the slope is also relatively large. Consequently, under the greater blowing pressure, the film at the lower end of the slope is also more tightly adhered, preventing the water flow channel from accumulating in the lower part of the slope and affecting the setting quality of the slope concrete.

[0035] A control center is integrated on the traveling vehicle 10. When the wind direction sensor 32 detects the wind direction and wind force, it can control the adjustment motor 24 to adjust the front and rear angle of the water spray, using the front and rear angle to counteract the influence of the wind force in the front and rear directions. When the tilt sensor 20 detects the slope angle, it controls the extension and retraction of the adjustment telescopic rod 41 to adjust the vertical angle of the water spray, using the vertical angle to counteract the influence of gravity, so that the sprayed water always falls vertically onto the slope.

[0036] Work or installation process: During maintenance, the traveling vehicle 10 moves along the slope, driving the water arm 12 and the water cylinder 22 to move along the slope. At this time, the water pump is started to pump water into the water cylinder 22 and spray it onto the slope through the atomizing nozzle 34 to maintain the slope. When strong winds occur, the water sprayed is tilted by the wind and cannot fall vertically onto the slope, affecting the maintenance effect. A wind direction sensor 32 is installed on the sprinkler arm 12. The wind direction sensor 32 can directly obtain the wind direction and wind force, and then control the motor 24 to output power, drive the gear 25 to rotate, and then drive the sprinkler cylinder 22 to deflect through the outer gear ring 23. This deflection of the sprinkler cylinder 22 at a certain angle makes the sprinkler cylinder 22 spray water at an angle, counteracting the wind force and ensuring that the sprayed water falls vertically onto the slope.

[0037] When maintaining an inclined slope, the tilt sensor 20 detects the tilt angle and controls the extension of the telescopic rod 41, which in turn drives the motion ring 40 to move. This causes the slip ring 42 to drive the rack 37 to move. Through the rack 37 and the mating wheel 38, the water spraying pipe 22 is deflected, tilting the water spraying angle of the water spraying pipe 22 upward, so that the water falls vertically onto the slope.

[0038] When the moving ring 40 moves, it drives the rotating ring 62 to rotate via the L-shaped rod 61. The torsion spring 63 then twists, causing the swing arm 46 to rotate, thus increasing the angle between the swing arm 46 and the slope. During maintenance, the pressure cylinder 45 adheres the maintenance film to the slope. When the slope angle is large, adjusting the telescopic rod 41 will drive the moving ring 40 to move, which in turn causes the torsion spring 63 to twist, causing the pressure cylinder 45 to adhere tightly to the slope, increasing the adhesion of the film and preventing it from slipping off due to insufficient adhesion.

[0039] During membrane covering, the air pump 47 is activated to introduce air into the tensioning cylinder 44 and the pressure cylinder 45. The air in the tensioning cylinder 44 is discharged through the inclined pipe 60, forming an airflow that blows outwards, thereby tensioning the membrane. Simultaneously, the airflow introduced into the pressure cylinder 45 is blown out through the through-hole, adhering the membrane to the slope surface and preventing it from failing to adhere due to slope indentation. Furthermore, because the inclined pipe 60 is tilted, the angle between the airflow direction and the slope surface is equal to the first angle, which is a small acute angle. This allows the airflow blowing through the inclined pipe 60 to overcome gravity on the slope surface, preventing water from flowing directly downhill. This ensures that water remains at the upper part of the slope surface during subsequent membrane covering, guaranteeing the curing effect.

[0040] When the slope angle is too large, the output power of the air pump 47 is increased, causing the airflow to blow the follower cover 58, which in turn moves the telescopic head 56, compressing the spring 59. This causes the abutment block 57 and the movable rod 51 to deflect, which in turn moves the sliding head 53. This increases the area of ​​the vent 54 exposed above the annular cover 50, increasing the airflow from the vent 49. The airflow then pushes the membrane tightly against the slope, increasing the adhesion and preventing the membrane from slipping off. Furthermore, because the exposed area of ​​the vent 54 near the lower end is larger, the airflow from the vent 49 at the lower end of the slope is also larger. Consequently, under greater blowing pressure, the membrane adhesion at the lower end of the slope is also stronger, preventing water flow from accumulating at the lower end of the slope and affecting the setting quality of the slope concrete.
