[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] like Figure 1 and Figure 2 As shown, a bridge pier color difference spraying repair device includes: a mixing chamber 20, which is a hollow cylinder with a handle installed on the side wall of the mixing chamber 20, and a motor 21 fixedly connected to the top of the mixing chamber 20 at an eccentric position. The bottom of the mixing chamber 20 is an inclined surface that converges towards the middle.

[0029] The connector 22 is in the shape of a round tube and is fixedly connected to the top center of the mixing chamber 20. The connector 22 has threads on its arc surface and its bottom can pass through the top of the mixing chamber 20. A through pipe 23 is fixedly connected to the bottom of the connector 22. The motor 21 is powered by a storage battery. This is existing technology and will not be described in detail here.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a hybrid structure is installed inside the mixing chamber 20 to agitate the pigment within the chamber. The hybrid structure includes a rotating tube 32, a crossbar 34, an arc rod 35, and a drive wheel 36. The rotating tube 32 is installed inside the mixing chamber 20. The crossbars 34 are symmetrically fixed to the walls of the rotating tube 32. The arc rods 35 are fixed to the walls of each crossbar 34. The drive wheel 36 is rotatably connected to an eccentric position at the top of the mixing chamber 20. The motor 21 can drive the drive wheel 36 to rotate, and the rotating tube 32 can drive the crossbars 34 and arc rods 35 to rotate within the mixing chamber 20.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the rotating tube 32 is cylindrical, and the crossbars 34 are rectangular. The crossbars 34 are symmetrically arranged at the bottom of the cavity of the rotating tube 32. The arc rods 35 are connected to the ends of each crossbar 34. The arc rods 35 are arc-shaped rods, and the inner arcs of the symmetrical arc rods 35 face each other. The top wall of the cavity of the rotating tube 32 is provided with teeth in a ring. The drive wheel 36 is gear-shaped and can mesh with the teeth on the wall of the rotating tube 32. The hybrid structure also includes a limiting rail 30, a limiting groove 31, and a limiting ring 33. The limiting rails 30 are symmetrically fixed to the inner wall of the mixing chamber 20. The limiting grooves 31 are formed on the opposite sides of the cavity. The limiting rails 30 face each other on their respective walls. The limiting ring 33 is fixedly connected to the bottom of the outer wall of the rotating tube 32. The limiting rails 30 are arc-shaped rods. The rotating tube 32 is located in the inner arc of the limiting rails 30. There is a gap between the two ends of the symmetrical limiting rails 30. The limiting groove 31 is a groove with a semi-circular cross section. The limiting ring 33 is a ring with a semi-circular cross section. The limiting ring 33 can rotate within the symmetrical limiting groove 31. The through tube 23 is located between the symmetrical arc rods 35. The symmetrical arc rods 35 can rotate around the through tube 23. The through tube 23 is cylindrical. The bottom of the through tube 23 can contact the bottom of the mixing chamber 20.

[0032] In practical use, the pigments and adhesives for preparing the repair solution are added into the cavity of the mixing chamber 20 through the joint 22. After all the raw materials for preparing the repair solution are added into the cavity of the mixing chamber 20, the power of the motor 21 is turned on. The motor 21 can drive the drive wheel 36 to rotate. When the drive wheel 36 rotates, it will be driven to rotate in the cavity of the mixing chamber 20 through the meshing teeth on the wall of the rotating tube 32. When the rotating tube 32 rotates, it will drive the limiting ring 33 to rotate in the symmetrical limiting groove 31. The cross bar 34 and the arc bar 35 will stir and mix the raw materials in the cavity of the mixing chamber 20 when the rotating tube 32 rotates.

[0033] In summary, by setting up a hybrid structure, the raw materials for preparing bridge pier repair fluid can be stored and mixed, eliminating the need for manual mixing by workers. Furthermore, after preparation, the repair fluid does not need to be transferred to other containers for use; it can be used directly by installing a spray gun head. This solution reduces a significant number of steps in the preparation of repair fluid, thereby alleviating the workload of workers.

[0034] like Figure 1 and Figure 5As shown, the top of the mixing chamber 20 is symmetrically provided with discharge ports 24, and each discharge port 24 is fitted with a plug 25. The top of the symmetrical plugs 25 is fixedly connected with a connecting ring 26. The discharge port 24 is located directly above the spacing of the symmetrical limiting grooves 31. The discharge port 24 is an arc-shaped groove. The plug 25 can block the discharge port 24. The connecting ring 26 is circular and can be connected to the symmetrical plugs 25 at the same time.

[0035] In practical use, when it is necessary to pour out the original liquid in the mixing chamber 20, the connecting ring 26 and the stopper 25 are removed directly from the top of the mixing chamber 20. At this time, the discharge port 24 will be open, and the original liquid in the mixing chamber 20 can be poured out through the discharge port 24.

[0036] In summary, by setting the discharge port 24, the mixing chamber 20 can be emptied directly by opening the discharge port 24 when it is necessary to pour out the liquid in the mixing chamber 20, which effectively improves the practicality of the device.

[0037] Working principle: The pigments and adhesives for preparing the repair solution are added into the mixing chamber 20 through the connector 22. After all the raw materials for preparing the repair solution are added into the mixing chamber 20, the power supply of the motor 21 is turned on. The motor 21 drives the drive wheel 36 to rotate. When the drive wheel 36 rotates, it will be driven to rotate in the mixing chamber 20 through the meshing teeth on the wall of the rotating tube 32. When the rotating tube 32 rotates, it will drive the limiting ring 33 to rotate in the symmetrical limiting groove 31. The crossbar 34 and the arc bar 35 will stir and mix the raw materials in the mixing chamber 20 when the rotating tube 32 rotates. After the crossbar 34 and the arc bar 35 have stirred the mixing chamber 20 for a period of time, the hose of the spray gun head can be inserted into the connector 22 and the connecting pipe 23. Then, the spray gun head is assembled and installed through the threads on the wall of the connector 22. At this time, the repair solution prepared in the mixing chamber 20 can be sprayed onto the bridge pier to be repaired.
