Description

Technical Field

[0001] The utility model belongs to the field of road construction, and in particular relates to intelligent spraying and maintenance equipment for a road structure layer. Background Art

[0002] In the process of municipal engineering road construction, the maintenance of each layer of the road structure is a key link in the entire road construction. The degree of maintenance directly affects the quality of the coring of the structure layer, and then determines the node of the next process. The traditional maintenance method is mostly to use a sprinkler truck to spray water on the surface of the road structure layer. With the development and progress of science and technology, automatic maintenance spraying devices have gradually appeared in the maintenance of the road structure layer. The spraying device can be controlled to spray water at intervals. However, the current automatic maintenance spraying device is not only complex in structure, but also only sprays at intervals. It is impossible to control the amount of spraying water according to the actual situation of the structure layer. In order to achieve the best maintenance effect of the road structure layer, it is necessary to detect the humidity of the structure layer and maintain the humidity of the road structure layer within the optimal moisture content range to achieve the best maintenance effect. Therefore, in the construction of municipal engineering roads, there is an urgent need for a device that can adjust the spraying maintenance according to the humidity. Summary of the invention

[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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.

[0014] This embodiment includes a plurality of tripods 1, and a tripod 1 is placed at a certain distance along the length of the road. The tripod 1 used includes three legs, and a central axis 2 is arranged in the middle. The difference from the conventional tripod 1 is that the central axis 2 is a hollow steel pipe, and the central axis 2 serves as a water supply pipe. A nozzle 3 is connected to the top of the central axis 2, and the nozzle 3 preferably adopts a rotating nozzle. The nozzle 3 is connected to the solenoid valve 4, and the opening and closing of the nozzle 3 are controlled by the solenoid valve 4, and the solenoid valve 4 is installed on the central axis 2. A three-way pipe 5 is connected to the bottom end of the central axis 2, and the three-way pipes 5 of adjacent tripods 1 are connected together through a rubber hose, that is, the water supply pipes of several tripods 1 are connected in series. The three-way pipe 5 of the tripod 1 at any end is connected to a water pump through a rubber hose, and the water pump is connected to a water source. The water source can be a water well, a water truck, a water tank, etc., and water is supplied to the central axis 2 of each tripod 1 through the water pump.

[0015] An intelligent control unit 6 is fixed on the central axis 2. The intelligent control unit 6 is a microcomputer controller. The intelligent control unit 6 is connected to the solenoid valve 4 by an upward wire, and is connected to the plug-in hygrometer 7 by a downward wire. The plug-in hygrometer 7 is used to measure the humidity of the road structure layer. The plug-in hygrometer 7 transmits the humidity data to the intelligent control unit 6. A minimum humidity threshold and a maximum humidity threshold are set in the intelligent control unit 6. When the humidity data transmitted to the intelligent control unit 6 by the plug-in hygrometer 7 is lower than the set minimum humidity threshold, the intelligent control unit 6 controls the solenoid valve 4 corresponding to the plug-in hygrometer 7 to open the nozzle 3, and the nozzle 3 performs spray maintenance; when the humidity data transmitted to the intelligent control unit 6 by the plug-in hygrometer 7 is higher than the set maximum humidity threshold, the intelligent control unit 6 controls the solenoid valve 4 corresponding to the plug-in hygrometer 7 to close the nozzle 3 and stop spray maintenance, so that segmented and situation-based spray maintenance can be achieved.

[0016] To facilitate remote control of the entire maintenance equipment, preferably, the intelligent control unit 6 is wirelessly connected to a human-machine interaction unit such as a mobile phone, a computer, etc., and remote control is achieved through the human-machine interaction unit. Remote control of the human-machine interaction unit is an existing mature technology and will not be described in detail here.

[0017] During the specific construction, several tripods 1 are placed at intervals along the length of the road, and the three-way pipes 5 of adjacent tripods 1 are connected to each other through rubber hoses. The three-way pipes 5 of the tripod at the front or rear end are connected to a water pump through a rubber hose, and the water pump is connected to a water source. The direct-insertion hygrometers 7 on each tripod 1 are respectively inserted into the road structure layer to be maintained, and the insertion point of the direct-insertion hygrometer 7 is generally located in the middle of the road. According to the actual situation of the construction site and the maintenance requirements of the road structure layer, the minimum humidity threshold and the maximum humidity threshold are set in the intelligent control unit 6. During operation, the intelligent control unit 6 receives the humidity data transmitted by the direct-insertion hygrometer 7, and the intelligent control unit 6 compares the received humidity data with the minimum humidity threshold and the maximum humidity threshold. If the humidity data is lower than the minimum humidity threshold, the electromagnetic valve 4 on the tripod 1 corresponding to the direct-insertion hygrometer 7 is controlled to open the nozzle 3, and the nozzle 3 sprays water for maintenance. The direct-insertion hygrometer 7 transmits the humidity data to the intelligent control unit 6 in real time. When the humidity data is higher than the maximum humidity threshold, the intelligent control unit 6 controls the electromagnetic valve 4 to close the nozzle 3 and stop the spraying maintenance; if the transmitted humidity data is between the minimum humidity threshold and the maximum humidity threshold, the electromagnetic valve 4 does not act. The present invention can also perform spraying maintenance work through remote control of the human-computer interaction unit.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
