Description

Technical Field

[0001] This application relates to the field of road snow melting technology, and in particular to a road snow melting agent spraying device triggered by a temperature and humidity sensor. Background Technology

[0002] In areas with frequent winter snowfall, snow accumulation on roads can severely impact normal traffic flow and safety. During snowfall, de-icing agents are typically spread on roads to prevent snow accumulation and ensure vehicle safety.

[0003] Traditional methods of road snow removal include manual application of de-icing agents and spraying de-icing agent solutions onto the road surface using spray trucks. However, manual application of de-icing agents is inefficient, labor-intensive, and struggles to ensure timely and even coverage of the entire road surface. Manual operation is also limited by weather conditions and worker physical limitations, often failing to respond quickly when heavy snowfall occurs or over a large area, leading to prolonged periods without effective snow removal and causing traffic congestion or even accidents. Spraying de-icing agent solutions from spray trucks also presents challenges. Dispatching and preparing the trucks takes time when heavy snowfall occurs or over a large area, hindering rapid snow removal operations. Furthermore, the relatively slow vehicle speed means that completing a single road spraying operation takes a considerable amount of time, resulting in delayed snow removal and potentially causing traffic congestion or even accidents.

[0004] Therefore, we propose a road de-icing agent spraying device triggered by a temperature and humidity sensor to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a road de-icing agent spraying device triggered by a temperature and humidity sensor, which can realize intelligent spraying of de-icing agent solution, greatly reduce manual intervention, improve work efficiency, respond to road snow accumulation in a timely manner, and ensure road traffic safety.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a road de-icing agent spraying device triggered by a temperature and humidity sensor, comprising a base fixedly mounted on the side of the road and a de-icing agent capacity tank and a booster pump fixedly mounted on the top of the base. The de-icing agent capacity tank is used to hold de-icing agent solution. A suction pipe is fixedly connected to the suction end of the booster pump, and one end of the suction pipe extends into the de-icing agent capacity tank. A main delivery pipe is fixedly connected to the discharge end of the booster pump. Multiple sets of de-icing agent spraying mechanisms are arranged evenly on the main delivery pipe. The de-icing agent spraying mechanisms are used to spray de-icing agent solution onto the road surface. An L-shaped bracket is fixedly mounted on the top of the de-icing agent capacity tank. A controller, a temperature and humidity sensor, and an ultrasonic snow depth sensor are fixedly mounted on the L-shaped bracket. The temperature and humidity sensor, the ultrasonic snow depth sensor, and the booster pump are all electrically connected to the controller.

[0007] By adopting the above technical solution, the booster pump is used to pump the de-icing agent solution in the de-icing agent capacity tank, and the infusion main pipe is used to transport the pumped de-icing agent solution, so that the de-icing agent solution can be sprayed from multiple sets of de-icing agent spraying mechanisms onto the road surface. The temperature and humidity sensor is used to monitor the ambient temperature and humidity around the road in real time, and the ultrasonic snow depth sensor is used to collect snow depth data on the road.

[0008] A further configuration of this application is as follows: the de-icing agent spraying mechanism includes a delivery branch pipe, a solenoid valve, a mounting base, a spray pipe, a nozzle, a shield, and a drive assembly. One end of the delivery branch pipe is fixedly connected to the main delivery pipe, and the other end of the delivery branch pipe is a closed structure. The solenoid valve and the mounting base are both fixedly installed on the delivery branch pipe. The spray pipe is rotatably installed on the mounting base, and the bottom end of the spray pipe extends into the delivery branch pipe. The nozzle is fixedly installed on the top end of the spray pipe and is inclined upwards. The shield is fixedly installed on the top of the mounting base, and a through hole is opened on the top of the shield. The top end of the spray pipe moves through the through hole. The drive assembly is disposed between the mounting base and the shield, and the drive assembly is used to control the reciprocating oscillation of the spray pipe.

[0009] By adopting the above technical solution, the nozzle is used to spray the de-icing agent solution onto the road surface, the solenoid valve is used to control the on / off state of the liquid delivery branch pipe, and the shield is used to shield and protect the drive components.

[0010] A further configuration of this application is as follows: the drive assembly includes a spur gear, a torsion spring, a motor, and a sector gear. The spur gear is fixedly mounted on the spray pipe, the torsion spring is fixedly mounted on the top of the spur gear, the top end of the torsion spring is fixedly connected to the inner wall of the top of the shield, the torsion spring is sleeved on the spray pipe, the motor is fixedly mounted on the top of the mounting base, the sector gear is fixedly mounted on the output shaft end of the motor, and the sector gear and the spur gear mesh intermittently.

[0011] By adopting the above technical solution, the motor can control the rotation of the sector gear. Utilizing the intermittent meshing transmission between the sector gear and the spur gear, and through the torsional deformation generated by the torsion spring, the spray pipe can drive the nozzle to oscillate back and forth. This allows the de-icing agent solution sprayed by the nozzle to cover a wider and more uniform area, enabling large-scale and precise snow melting treatment of road surfaces and improving the snow melting effect.

[0012] A further feature of this application is that a notch is provided at the bottom of one side of the shield.

[0013] By adopting the above technical solution, it is ensured that the sector gear will not come into contact with the shield when it rotates.

[0014] A further feature of this application is that a slanted support rod is fixedly installed on one side of the outer wall of the shield, and an arc-shaped dispersion net is fixedly installed at one end of the slanted support rod, the arc-shaped dispersion net being adapted to the nozzle.

[0015] By adopting the above technical solution, the de-icing agent solution sprayed from the nozzle can be further dispersed, making it more evenly distributed on the road surface, thereby improving the utilization rate of the de-icing agent solution and enhancing the snow melting effect.

[0016] A further feature of this application is that both the solenoid valve and the motor are electrically connected to the controller.

[0017] By adopting the above technical solution, the controller can be used to control the opening and closing of the solenoid valve and motor.

[0018] A further feature of this application is that the de-icing agent capacity tank is provided with a stirring mechanism, which is used to stir the de-icing agent solution in the de-icing agent capacity tank. The stirring mechanism includes a second motor, a vertical shaft and multiple stirring blades. The second motor is fixedly installed at the top center of the de-icing agent capacity tank. The output shaft end of the second motor extends into the de-icing agent capacity tank. The vertical shaft is fixedly installed at the output shaft end of the second motor. The multiple stirring blades are all fixedly installed on the vertical shaft and are evenly distributed.

[0019] By adopting the above technical solution, motor 2 can control the rotation of the vertical shaft and multiple stirring blades, which can stir the de-icing agent solution in the de-icing agent capacity tank, prevent the de-icing agent solution from settling, ensure uniform solution concentration, and thus ensure that the sprayed de-icing agent solution always maintains good snow melting performance and ensures the stability of the snow melting effect.

[0020] A further provision of this application is that the second motor is electrically connected to the controller.

[0021] By adopting the above technical solution, the controller can control the opening and closing of motor two.

[0022] This application includes at least one of the following beneficial technical effects:

[0023] 1. This application, through the synergistic action of a controller, a temperature and humidity sensor, an ultrasonic snow depth sensor, and a snow-melting agent spraying mechanism, enables intelligent spraying of snow-melting agent solution, greatly reducing manual intervention, improving work efficiency, and enabling timely response to road snow accumulation, thus ensuring road traffic safety.

[0024] 2. The design of the mixing mechanism in this application can prevent the snow-melting agent solution in the snow-melting agent capacity tank from settling during the process of spraying the snow-melting agent solution on the road surface, so that the solution concentration is always kept uniform and the sprayed snow-melting agent solution can continuously have good snow-melting performance, thereby further improving the snow-melting effect on the road.

[0031] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] See Figures 1-5 This application provides a road de-icing agent spraying device triggered by a temperature and humidity sensor, including a base 1 fixedly mounted on the side of the road, a de-icing agent capacity tank 2 and a booster pump 3 fixedly mounted on the top of the base 1. The de-icing agent capacity tank 2 is used to hold de-icing agent solution. The suction end of the booster pump 3 is fixedly connected to a suction pipe 4, one end of which extends into the de-icing agent capacity tank 2. The discharge end of the booster pump 3 is fixedly connected to a main infusion pipe 5. The base 1 and the main infusion pipe 5 can be fixed to a suitable position on the side of the road with pipe clamps without affecting the normal driving of vehicles. Multiple sets of de-icing agent spraying mechanisms 6 are arranged evenly on the main infusion pipe 5. The de-icing agent spraying mechanisms 6 are used to spray de-icing agent solution onto the road surface.

[0033] In this embodiment, the de-icing agent spraying mechanism 6 includes a liquid delivery branch pipe 601, a solenoid valve 602, a mounting base 603, a spray pipe 604, a nozzle 605, a shield 610, and a drive assembly. One end of the liquid delivery branch pipe 601 is fixedly connected to the main liquid delivery pipe 5, and the other end of the liquid delivery branch pipe 601 is a closed structure. The solenoid valve 602 and the mounting base 603 are both fixedly installed on the liquid delivery branch pipe 601. The spray pipe 604 is rotatably installed on the mounting base 603, and the bottom end of the spray pipe 604 extends into the liquid delivery branch pipe 601. The nozzle 605 is fixedly installed on the top end of the spray pipe 604 and is inclined upward. The shield 610 is fixedly installed on the top of the mounting base 603. A through hole is opened on the top of the shield 610, and the top end of the spray pipe 604 moves through the through hole. The drive assembly is disposed between the mounting base 603 and the shield 610, and the drive assembly is used to control the reciprocating swing of the spray pipe 604.

[0034] In this embodiment, the drive assembly includes a spur gear 606, a torsion spring 607, a motor 608, and a sector gear 609. The spur gear 606 is fixedly mounted on the spray pipe 604. The torsion spring 607 is fixedly mounted on the top of the spur gear 606, and the top end of the torsion spring 607 is fixedly connected to the inner top wall of the shield 610. The torsion spring 607 is sleeved on the spray pipe 604. The motor 608 is fixedly mounted on the top of the mounting base 603. The sector gear 609 is fixedly mounted on the output shaft end of the motor 608. The sector gear 609 intermittently meshes with the spur gear 606. The operation of the motor 608 drives the sector gear 609 to rotate, which in turn causes the sector gear 609 to intermittently mesh with the spur gear 606. Through the torsional deformation of the torsion spring 607, the spray pipe 604 drives the nozzle 605 to reciprocate, making the de-icing agent solution sprayed by the nozzle 605 cover a wider and more even area. This enables large-scale and precise snow melting treatment of road surfaces, improving the snow melting effect.

[0035] In this embodiment, a notch is provided at the bottom of one side of the shield 610 to ensure that the sector gear 609 will not touch the shield 610 when it rotates, thus ensuring that the sector gear 609 rotates smoothly.

[0036] In this embodiment, a diagonal support rod 611 is fixedly installed on one side of the outer wall of the shield 610. An arc-shaped dispersion net 612 is fixedly installed at one end of the diagonal support rod 611. The arc-shaped dispersion net 612 is adapted to the nozzle 605. The design of the arc-shaped dispersion net 612 can further disperse the de-icing agent solution sprayed by the nozzle 605, making it more evenly distributed on the road surface, thereby improving the utilization rate of the de-icing agent solution and enhancing the snow melting effect.

[0037] In this embodiment, a stirring mechanism 7 is provided on the de-icing agent capacity tank 2. The stirring mechanism 7 is used to stir the de-icing agent solution in the de-icing agent capacity tank 2. The stirring mechanism 7 includes a second motor 701, a vertical shaft 702, and multiple stirring blades 703. The second motor 701 is fixedly installed at the top center of the de-icing agent capacity tank 2. The output shaft end of the second motor 701 extends into the de-icing agent capacity tank 2. The vertical shaft 702 is fixedly installed at the output shaft end of the second motor 701. The multiple stirring blades 703 are all fixedly installed on the vertical shaft 702 and are evenly distributed. When the second motor 701 is running, it can control the rotation of the vertical shaft 702 and the multiple stirring blades 703, which can stir the de-icing agent solution in the de-icing agent capacity tank 2, prevent the de-icing agent solution from settling, ensure uniform solution concentration, and thus ensure that the sprayed de-icing agent solution always maintains good snow melting performance and ensures the stability of the snow melting effect.

[0038] In this embodiment, an L-shaped bracket 8 is fixedly installed on the top of the de-icing agent capacity tank 2. A controller 9, a temperature and humidity sensor 10, and an ultrasonic snow depth sensor 11 are fixedly installed on the L-shaped bracket 8. The temperature and humidity sensor 10, the ultrasonic snow depth sensor 11, and the booster pump 3 are all electrically connected to the controller 9. The height of the ultrasonic snow depth sensor 11 from the ground is set to 80-120 cm, thus ensuring accurate monitoring of the snow depth on the road surface. The solenoid valve 602 and motor 608 are both electrically connected to the controller 9, and motor 701 is also electrically connected to the controller 9. Using the temperature and humidity sensor 10 and the ultrasonic snow depth sensor 11, the ambient temperature and humidity around the road and the snow depth on the road can be monitored in real time, respectively. The obtained temperature and humidity data and snow depth data are transmitted to controller 9. Controller 9 can automatically control the start and stop of booster pump 3, solenoid valve 602, motor 1 608, and motor 2 701 according to the set threshold, realizing intelligent spraying of de-icing agent solution. This greatly reduces manual intervention, improves work efficiency, and can respond promptly to road snow conditions, ensuring road traffic safety. It should be noted that the control method of booster pump 3, solenoid valve 602, motor 1 608, and motor 2 701 is automatically controlled by controller 9. The control circuit of controller 9 can be implemented by simple programming by those skilled in the art and is common knowledge in the field, so the control method and circuit connection method will not be explained in detail.

[0039] With the above structure, the road de-icing agent spraying device triggered by the temperature and humidity sensor provided in this application can monitor the temperature and humidity in the environment and the snow depth on the road in real time using the temperature and humidity sensor 10 and the ultrasonic snow depth sensor 11 respectively. The temperature and humidity data sensed by the temperature and humidity sensor 10 and the snow layer thickness data measured by the ultrasonic snow depth sensor 11 are transmitted to the controller 9. After receiving these data, the controller 9 will send an electrical signal according to the preset thresholds for temperature, humidity and snow depth. When the actual monitoring data reaches or exceeds the set thresholds, the controller 9 will automatically control the booster pump 3, solenoid valve 602, motor 1 608 and motor 2 701 to start the road de-icing operation.

[0040] When the snow melting operation begins, the booster pump 3 starts running and draws snow melting agent solution from the snow melting agent capacity tank 2 through the suction pipe 4. The solution is then transported through the main inlet pipe 5 to the inlet branch pipes 601 of the multiple snow melting agent spraying mechanisms 6. Under pressure, the snow melting agent solution in the inlet branch pipes 601 enters the spray pipes 604 and is sprayed onto the road surface from the nozzles 605. Simultaneously, the operation of the motor 608 drives the sector gear 609 to rotate via its output shaft. The sector gear 609 intermittently meshes with the spur gear 606. When they mesh, the spur gear 606 rotates, driving the spray pipes 604 and nozzles 605. When the 605 rotates, the torsion spring 607 twists. When the sector gear 609 disengages from the spur gear 606, the torsion spring 607 automatically resets, causing the spray pipe 604 and the nozzle 605 to rotate in the opposite direction. This achieves the reciprocating oscillation of the spray pipe 604 and the nozzle 605, expanding the coverage area of ​​the de-icing agent solution sprayed by the nozzle 605, and achieving precise and uniform spraying. During the spraying of the de-icing agent solution, the de-icing agent solution sprayed by the nozzle 605 is further dispersed after contacting the arc-shaped dispersion net 612, and evenly distributed on the road surface, thereby improving the utilization rate of the de-icing agent and enhancing the snow melting effect.

[0041] When the snow melting operation begins, the output shaft of motor 701 drives the vertical shaft 702 to rotate. Multiple stirring blades 703 evenly distributed on the vertical shaft 702 rotate accordingly. During the rotation, the stirring blades 703 stir the snow melting agent solution to prevent the snow melting agent solution from settling and keep the solution concentration uniform, ensuring that the sprayed snow melting agent solution can continuously have good snow melting performance.

[0042] When the data monitored in real time by the temperature and humidity sensor 10 and the ultrasonic snow depth sensor 11 are lower than the set threshold, the controller 9 will send an electrical signal to automatically control the booster pump 3, solenoid valve 602, motor 1 608 and motor 2 701 to shut down.
