[0023] The following further describes the present utility model in detail in conjunction with the drawings and the specific embodiments: Refer to Figures 1 - 5, A concrete panel crack detection device includes a detection trolley 1. The trolley includes several running wheels which are used to normally operate the detection trolley 1. At the same time, a detection unit 2 is arranged on the detection trolley 1, and the detection unit 2 can detect cracks on the concrete under the existing technology.

[0024] Furthermore, for the convenience of the marking work after detecting cracks, a marking unit is arranged on the detection trolley 1. The marking unit can be arranged on one side of the detection unit 2 to improve the accuracy of marking.

[0025] The marking unit includes a spraying cylinder body 3 and a piston part 4 that is hermetically movable in the spraying cylinder body 3. At least one outlet 5 is arranged at the bottom of the spraying cylinder body 3. In this embodiment, the number of outlets 5 is 1. After the piston part 4 moves towards the outlet 5, the flow direction in the spraying cylinder body 3 will flow towards the outlet 5. At this time, when there is spraying raw material in the spraying cylinder body 3, marking at this place is achieved.

[0026] At the same time, an inlet 6 is arranged on the side wall of the spraying cylinder body 3, and the number of the inlets 6 is also at least 1. In this embodiment, the number of the inlets 6 is 2, and they are symmetrically arranged on the side of the spraying cylinder body 3. Furthermore, the outlet 5 is arranged lower than the inlet 6 to ensure the normal use of the outlet 5.

[0027] Furthermore, a first one-way valve 7 is arranged at the outlet 5, and a second one-way valve 8 is arranged at the inlet 6. Among them, the flow direction of the first one-way valve 7 is from the inside of the spraying cylinder body 3 to the outside, and the flow direction of the second one-way valve 8 is from the outside of the spraying cylinder body 3 to the inside. Therefore, when the piston part 4 moves away from the spraying cylinder body 3, the inlet 6 is a passage and the outlet 5 is a closed circuit; conversely, the inlet 6 is a closed circuit and the outlet 5 is a passage, so as to achieve pressure balance between the inlet 6 and the outlet 5 all the time.

[0028] For controlling the movement of the piston part 4, a control unit is arranged on the spraying cylinder body 3. The control unit includes a control rod 10 and a spring 11. The control rod 10 passes through the top of the spraying cylinder body 3. One end of the control rod 10 located inside the spraying cylinder body 3 is fixedly connected to the piston rod, and the other end slides on the top of the spraying cylinder body 3.

[0029] Further, a spring 11 is provided between the piston member 4 and the spraying cylinder block 3. The spring 11 can be arranged between the piston member 4 and the top of the spraying cylinder block 3, or between the piston member 4 and the bottom of the spraying cylinder block 3. Both can achieve the reset of the piston member 4. That is, in the static state, the piston member 4 is arranged close to the top of the spraying cylinder block 3. In this embodiment, the spring 11 passes through the control rod 10 and is arranged between the piston member 4 and the top of the spraying cylinder block 3. When the spring 11 is under no external force, the piston member 4 is placed close to the top of the spraying cylinder block 3.

[0030] Meanwhile, an eccentric wheel 12 is rotatably arranged outside the control rod 10. The eccentric wheel 12 is connected to the output shaft 13 of the rotating motor. When the rotating motor is started, due to the action of the spring 11, the eccentric wheel 12 continuously abuts against the control rod 10. Under the continuous rotation of the eccentric wheel 12, the control rod 10 moves repeatedly, thereby realizing marking, and the marking is continuous.

[0031] Meanwhile, storage containers 9 corresponding to the number of inlets 6 are arranged outside the spraying cylinder block 3. The storage containers 9 and the inlets 6 are provided with through holes for communicating, and the two can realize the circulation of liquid. The storage containers 9 are used to provide spraying raw materials. Generally, spraying pigments can be selected as colored liquids, which can act significantly on the ground to realize cleaning marks. At the same time, in order to facilitate a larger spraying range of the liquid, a nozzle 14 is arranged at the bottom of the outlet 5, which can disperse the liquid and expand the display mark.

[0032] Regarding the start of the rotating motor, the rotating motor can be electrically connected to the detection unit 2. When the detection unit 2 detects a crack, the rotating motor can be started by transmitting a sensor signal or a PLC control signal through the electrical connection. This connection relationship is very mature in the prior art.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
