[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0025] This application provides a high-temperature and high-pressure spraying experimental device.

[0026] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the high-temperature and high-pressure spraying experimental equipment includes a water tank 100, a high-pressure water pump 200, a swinging component 201, a spraying component 202, a placement platform 203, and a servo motor 204.

[0027] A heater 101 is installed inside the water tank 100. The inlet of the high-pressure water pump 200 is connected to the water tank 100. The spray element 202 is fixedly connected to the swing element 201, and the inlet of the spray element 202 is connected to the outlet of the high-pressure water pump 200. The placement platform 203 is located near the outlet of the spray element 202. The drive shaft of the servo motor 204 is fixedly connected to the bottom surface of the placement platform 203.

[0028] In this embodiment, the test specimen is placed on the top surface of the platform 203. The water in the water tank 100 is transported to the spraying component 202 by the high-pressure water pump 200, and the water is sprayed onto the test specimen by the spraying component 202 to complete the spraying experiment on the test specimen. During the experiment, the servo motor 204 works to drive the platform 203 to rotate, so that the test specimen on the top surface of the platform 203 rotates synchronously, so that the spraying of the test specimen is more uniform. The swing component 201 works to adjust the angle of the spraying component 202 relative to the platform 203, so as to avoid the occurrence of spray dead angles.

[0029] like Figure 3 As shown, in one embodiment of this application, the swinging component 201 includes a swinging cylinder 205 and a swinging plate 206. The swinging plate 206 is fixedly connected to the drive rod of the swinging cylinder 205, and the spraying component 202 is fixedly connected to the swinging plate 206. The angle of the spraying component 202 is adjusted by driving the swinging plate 206 to rotate through the swinging cylinder 205.

[0030] Specifically, a sealing element 212 is also provided between the swing cylinder 205 and the swing plate 206 to maintain the sealing of the swing cylinder 205.

[0031] The edge of the swing plate 206 has a fan-shaped notch with an angle of 90° to prevent the swing plate 206 from touching the storage platform 203 during rotation, thereby facilitating the swing plate 206 to rotate around the storage platform 203.

[0032] In this embodiment, the swing cylinder 205 drives the swing plate 206 to rotate, thereby driving the spray component 202 fixed on the swing plate 206 to rotate, thereby adjusting the angle of the spray component 202 relative to the placement platform 203, so that the spray component 202 sprays the test sample on the placement platform 203 more evenly.

[0033] like Figure 1 As shown, in one embodiment of this application, multiple spray elements 202 are provided, and the multiple spray elements 202 are arranged at equal intervals around the storage platform 203.

[0034] Specifically, the spray element 202 can be set to 4, and the angles of the 4 spray elements 202 can be set to 0°, 30°, 60° and 90° respectively (with the horizontal line as the reference).

[0035] In this embodiment, water is sprayed onto the surface of the test specimen through the spraying component 202 to complete the spraying test on the test specimen.

[0036] Multiple spray elements 202 are set at different angles, so that the spray elements 202 can spray the test sample from different directions at the same time, avoiding spray dead zones.

[0037] like Figure 2 As shown, in one embodiment of this application, the spraying component 202 includes a spray bar 207 and a nozzle 208. One end of the spray bar 207 is connected to a high-pressure water pump 200, and the nozzle 208 is fixedly connected to the other end of the spray bar 207. The outlet of the nozzle 208 is located near the storage platform 203.

[0038] In this embodiment, water in the water tank 100 is transported to the spray bar 207 by the high-pressure water pump 200, and finally sprayed onto the test sample by the nozzle 208.

[0039] Since the frequency of the high-pressure water pump 200 is adjustable, the frequency of the high-pressure water pump 200 can be set before starting the high-pressure water pump 200 so that the high-pressure water pump 200 can output water flow at different pressures.

[0040] like Figure 3 As shown, in one embodiment of this application, the high temperature and high pressure spraying experimental equipment further includes a rotating shaft 209. One end of the rotating shaft 209 is fixedly connected to a servo motor 204, and the other end of the rotating shaft 209 is fixedly connected to the bottom surface of the lifting platform. The rotating shaft 209 and the drive shaft of the servo motor 204 are arranged perpendicular to each other. The rotating shaft 209 is driven to rotate by the servo motor 204 to drive the placement platform 203 to rotate.

[0041] Specifically, the drive shaft of the servo motor 204 and the rotating shaft 209 are provided with mutually coupled gears to enable the servo motor 204 to drive the rotating shaft 209 to rotate.

[0042] The servo motor 204 includes three drive modes: 360° rotation in the same direction, 360° rotation in both positive and negative directions, and a time setting for pausing every 90° rotation.

[0043] In this embodiment, the test specimen is placed on the top surface of the platform 203. The servo motor 204 drives the rotating shaft 209 to rotate, thereby causing the platform 203 to rotate, so that the test specimen on the top surface of the platform 203 rotates synchronously.

[0044] The rotating shaft 209 changes the driving direction of the servo motor 204 from rotation perpendicular to the horizontal line to rotation parallel to the horizontal line, thereby enabling the platform 203 to rotate at a constant speed along with the rotation of the drive rod of the servo motor 204.

[0045] like Figure 1 As shown, in one embodiment of this application, the high-temperature and high-pressure spraying experimental equipment further includes a high-pressure solenoid valve 210. One end of the high-pressure solenoid valve 210 is connected to the outlet of the high-pressure water pump 200, and the other end of the high-pressure solenoid valve 210 is connected to the spray bar 207.

[0046] In this embodiment, the water circuit is controlled by a high-pressure solenoid valve 210, thereby adjusting the spraying time of the spraying component 202 on the test sample.

[0047] like Figure 1 As shown, in one embodiment of this application, multiple high-pressure solenoid valves 210 are provided, and at least one high-pressure solenoid valve 210 is provided between each spray bar 207 and the high-pressure water pump 200.

[0048] In this embodiment, each high-pressure solenoid valve 210 controls one spray element 202, so that the water path of each spray element 202 can be controlled independently, thereby adjusting the number of spray elements 202 that are opened at the same time, and thus adjusting the spraying efficiency.

[0049] like Figure 1 As shown, in one embodiment of this application, a flow meter 211 is provided between the high-pressure solenoid valve 210 and the spray bar 207. One end of the flow meter 211 is connected to the high-pressure solenoid valve 210, and the other end of the flow meter 211 is connected to the spray bar 207.

[0050] Specifically, a pressure sensor is also provided between the high-pressure water pump 200 and the high-pressure solenoid valve 210 to measure the water pressure of the water flow output by the high-pressure water pump 200.

[0051] Both the pressure sensor and the flow meter 211 are communicatively connected to the controller 301 to send the monitored data to the controller 301.

[0052] In this embodiment, the flow rate of the water passing through the high-pressure solenoid valve 210 is measured in real time by the flow meter 211 to ensure that the flow rate of the water output by the high-pressure water pump 200 reaches the set value, thereby ensuring the final spraying effect.

[0053] like Figure 3 As shown, in one embodiment of this application, a seal 212 is provided between the rotating shaft 209 and the placement platform 203 to maintain the sealing of the rotating shaft 209.

[0054] In this embodiment, the sealing performance of the rotating shaft 209 is improved by the sealing element 212, which prevents water from entering the rotating shaft 209 during spraying, thereby protecting the rotating shaft 209.

[0055] like Figure 3 and Figure 4 As shown, in one embodiment of this application, the high temperature and high pressure spraying experimental device further includes a control component 300. The control component 300 includes a controller 301, a first sensor 302, and a second sensor 303. The first sensor 302 is disposed in the water tank 100, and the second sensor 303 is disposed near the drive rod of the servo motor 204. Both the first sensor 302 and the second sensor 303 are communicatively connected to the controller 301.

[0056] Specifically, the controller 301 is a PLC, and the controller 301 adjusts the angle of the spray element 202 using only conventional and existing simple control logic. The angle adjustment of the spray element 202 does not need to rely on software or computer programs. The first sensor 302 is a temperature sensor, and the second sensor 303 is a photoelectric sensor.

[0057] In this embodiment, the water temperature in the water tank 100 is monitored in real time by the first sensor 302. When the water temperature in the water tank 100 is too low, the controller 301 starts the heater 101 to increase the water temperature in the water tank 100.

[0058] The rotation angle of the rotating shaft 209 is monitored by the second sensor 303 to ensure that the rotation angle of the placement platform 203 meets the requirements, thereby making the angle adjustment of the spraying equipment more precise.

[0059] The technical features of the above embodiments can be combined arbitrarily, and the execution order of the method steps is not restricted. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
