However, the nozzle of the existing maintenance spray device generally cannot be rotated arbitrarily, and the spraying range is small, which cannot cover most of the concrete wall surface. In order to solve this technical problem, the utility model proposes a concrete exterior wall maintenance spray device. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a concrete exterior wall maintenance spray device includes a water tank 1, a controller is installed on the upper surface of the water tank 1, the material of the water tank 1 is hard plastic, and the water tank 1 has a water inlet for easy water filling. A water pump 2 is arranged on one side of the water tank 1, and the water pump 2 is fixedly installed on the upper surface of a machine base 13. The material of the machine base 13 is a metal plate, which is used to support the entire main body. An electric valve 14 is installed at one end of the water pipe 3 away from the nozzle 4. The electric valve 14 is controlled by the controller and can adjust the valve size. A water pipe 3 is installed at the output end of the water pump 2, and the water pipe 3 is a soft water pipe and can adjust the direction.

[0024] A nozzle 4 is installed at one end of the water pipe 3 away from the water pump 2. The nozzle 4 is a high-pressure nozzle that can be removed and replaced. A protective shell 5 is installed on one side of the nozzle 4. The outer surface of the water pipe 3 contacts the inner wall of the protective shell 5. A connecting rod 6 is fixedly connected to one side of the protective shell 5. The connecting rod 6 is made of stainless steel. A rope 7 is installed on the outer surface of the connecting rod 6. There are four ropes 7, which are installed at four positions of the connecting rod 6, namely, up, down, left, and right. The rope 7 is made of a polymer waterproof rope, so that water cannot penetrate into the rope 7 to increase the service life. The four ropes 7 control the connecting rod 6 to rotate up, down, left, and right. The ends of the ropes 7 A power mechanism 8 is provided, and there are four power mechanisms 8 in total. The four ropes 7 correspond to the four power mechanisms 8 one by one, respectively. Three of the power mechanisms 8 are installed on the upper side of the support plate 12, and the other power mechanism 8 is installed on the lower side of the support plate 12. The power mechanism 8 includes a shell 801. The upper surface of the shell 801 located on the lower side of the support plate 12 is fixedly installed on the support plate 12. In the shell 801 located on the upper side of the support plate 12, the lower surfaces of two of the shells 801 are fixedly installed on the support plate 12, and the lower surface of the other shell 801 is fixedly installed on the support plate 12 through a round rod.

[0025] An electric motor 802 is arranged inside the outer shell 801. The electric motor 802 is a power source and can be rotated forward and reversely. A roller 803 is installed at the output end of the electric motor 802. The roller 803 is made of metal and is connected to the output end of the electric motor 802. The rope 7 runs through one side of the outer shell 801. The outer surface of the roller 803 is fixedly connected to one end of the rope 7. One end of the rope 7 is wrapped around the roller 803, and its end is fixed on the roller 803. The rotation of the roller 803 controls the scaling of the rope 7.

[0026] The side wall of the shell 801 is inlaid with a rubber sleeve 9 at the position of the rope 7, and the interior of the rubber sleeve 9 is slidably connected to the outer surface of the rope 7. When the rope 7 moves toward the inside of the shell 801, the mud and water stains on the rope 7 will be blocked by the rubber sleeve 9, thereby playing a cleaning role. A ball 10 is installed at the end of the connecting rod 6 away from the protective shell 5, and the two ends of the connecting rod 6 are respectively connected to the ball 10 and the protective shell 5. The outer surface of the ball 10 is slidably connected to the support seat 11, and the bottom end of the support seat 11 is fixedly connected to a support plate 12. The bottom of the support plate 12 is fixedly installed with a machine base 13, and the upper surface of the machine base 13 is fixedly installed with the water tank 1, and the water tank 1 and the machine base 13 are snap-fit ​​installed for easy disassembly.

[0027] It should be noted that, in actual use of the device, the water tank 1 is first filled with water, the spray device is placed in front of the target wall and the bottom wheels are fixed, the water pump 2 will pump water from the water tank 1, the water flow is pressurized by the water pump 2 and flows through the water pipe 3 to spray the water from the nozzle 4 to spray the target wall, the forward direction of the motor 802 will drive the roller 803 to rotate forward, thereby shortening the rope 7, and the reverse rotation of the motor 802 will drive the roller 803 to rotate reversely, thereby extending the rope 7, the upper and lower motors 802 cooperate with each other to make the connecting rod 6 move up and down, the left and right motors 802 cooperate with each other to make the connecting rod 6 move left and right, the rotation of the two motors 802 makes the connecting rod 6 move away from the end of the ball 10 in a larger range, the four motors 802 cooperate with each other to rotate and are controlled by a controller, the rotation of the connecting rod 6 drives the protective shell 5 to rotate in a larger range, and the rotation of the protective shell 5 drives the nozzle 4 to rotate in a larger range, so that the nozzle 4 can spray to a larger range, thereby achieving the effect of increasing the spraying range.

[0028] The diameter of the rubber sleeve 9 is smaller than the diameter of the rope 7. The inner wall of the rubber sleeve 9 will squeeze the rope 7. When the rope 7 moves into the housing 801, the mud and water stains on the rope 7 will be blocked by the rubber sleeve 9, so that the rope 7 can be cleaned when moving into the housing 801, thereby preventing the motor 802 from being corroded and keeping the inside of the power mechanism 8 clean.

[0029] When the nozzle 4 is spraying, the pitch angle is too large, which makes the distance that the water flow sprayed from the nozzle 4 moves in the air longer. The electric valve 14 opens the valve under the action of the controller to increase the spraying distance of the nozzle 4, so that the sprayed wall can be sprayed better to prevent the spraying effect from being poor due to insufficient power. When the nozzle 4 is spraying at a small pitch angle, the distance that the water flow sprayed from the nozzle 4 moves in the air becomes shorter. The electric valve 14 is reduced under the action of the controller to reduce the valve to reduce the spraying distance of the nozzle 4. While not affecting the spraying effect, it prevents the water flow speed from being too fast to cause splashing or damage to the wall, thereby achieving the effect of regulating the water flow rate.
