Description

Technical Field

[0001] This application relates to the field of special equipment testing technology, and in particular to an ultrasonic coupling agent spraying device suitable for special equipment. Background Technology

[0002] With the continuous advancement of industrial technology, the application fields of special equipment are constantly expanding, making it particularly important to ensure the safety and reliability of this equipment. Ultrasonic testing technology utilizes the propagation characteristics of high-frequency sound waves in materials to effectively identify internal defects such as cracks, pores, and inclusions. It is widely used in the safety inspection of special equipment to provide reliable technical support for the safety management of special equipment.

[0003] During ultrasonic testing of special equipment, inspectors typically need to hold the equipment in their left hand and the ultrasonic probe in their right. Simultaneously, ultrasonic coupling agent needs to be applied to the probe during the testing process. This necessitates frequent changes of the probe and the container containing the coupling agent, causing considerable inconvenience to the testing work. Especially when working at heights, the container after applying the coupling agent is difficult to position, leading to reduced testing efficiency and increased safety hazards. Utility Model Content

[0004] In view of this, this application provides an ultrasonic coupling agent spraying device suitable for special equipment, so as to improve the efficiency and safety of ultrasonic testing of special equipment.

[0005] Specifically, this application is implemented through the following technical solution:

[0006] This application provides an ultrasonic coupling agent spraying device suitable for special equipment, including a housing with a gripping part, a nozzle assembly, a suction pipe and a limit switch;

[0007] The top of the housing has a receiving groove, and the nozzle assembly is disposed in the receiving groove and can be switched between vertical and horizontal directions;

[0008] A limit switch is provided on the receiving groove to limit the movement of the nozzle assembly;

[0009] The top of the suction tube communicates with the nozzle assembly, and the rest of the suction tube is inserted into the interior of the housing;

[0010] In use, the ultrasonic coupling agent spraying device can be fixed to the hand through the grip part, and the limit switch can be controlled by the thumb to switch the nozzle assembly from the horizontal state to the vertical state. Then, the thumb can be continued to control the nozzle assembly to make the ultrasonic coupling agent in the box flow out from the nozzle assembly. After the ultrasonic coupling agent spraying is completed, the limit switch can be controlled by the thumb again to return the nozzle assembly from the vertical state to the horizontal state.

[0046] The following specific embodiments are given to illustrate the technical solution of this application in detail.

[0047] Figure 1 This is a perspective view of the ultrasonic coupling agent spraying device provided in this application. Figure 2 A schematic diagram of an ultrasonic coupling agent spraying device shown as an exemplary embodiment of this application ( Figure 2 In the example shown, the nozzle assembly is in a vertical position. Figure 3 A schematic diagram of an ultrasonic coupling agent spraying device shown as another exemplary embodiment of this application ( Figure 3 In the example shown, the nozzle assembly is in a horizontal position. Please also refer to... Figure 1 , Figure 2 and Figure 3 The ultrasonic coupling agent spraying device for special equipment provided in this embodiment includes a housing 1 with a gripping part 5, a nozzle assembly 2, a suction tube 3, and a limit switch 4.

[0048] The top of the housing 1 has a receiving groove 11, and the nozzle assembly 2 is disposed in the receiving groove 11 and can be switched between the vertical and horizontal directions;

[0049] A limit switch 4 is provided on the receiving groove 11 to limit the movement of the nozzle assembly 2;

[0050] The top of the suction tube 3 is connected to the nozzle assembly 2, and the rest of the suction tube 3 is inserted into the interior of the housing 1;

[0051] In use, the ultrasonic coupling agent spraying device is fixed to the hand by the grip part 5, and the limit switch 4 is controlled by the thumb to switch the nozzle assembly 2 from the horizontal state to the vertical state. Then, the thumb is continued to be operated to control the nozzle assembly 2, so that the ultrasonic coupling agent in the box 1 flows out from the nozzle assembly 2. After the ultrasonic coupling agent spraying is completed, the limit switch 4 is controlled by the thumb again to restore the nozzle assembly 2 from the vertical state to the horizontal state.

[0052] It should be noted that the ultrasonic coupling agent spraying device provided in this application is applicable to special equipment. Specifically, it is used to spray ultrasonic coupling agent onto special equipment when using ultrasonic equipment to inspect special equipment, thereby using ultrasonic equipment to inspect special equipment.

[0053] Specifically, housing 1 is the main structure of the ultrasonic coupling agent spraying device, and a receiving groove 11 is provided on its top. The nozzle assembly 2 can be placed inside the receiving groove 11. The width of the receiving groove 11 (refer to...) Figure 1 The width direction (perpendicular to the paper surface) is slightly larger than the nozzle assembly 2, so that the nozzle assembly 2 can move inside the receiving groove 11 to achieve state switching.

[0054] Please continue to refer to Figure 1 In one possible implementation, the housing 1 is a semi-cylindrical structure, the upper semi-circular part of the semi-cylindrical structure constitutes the top of the housing, the lower semi-circular part of the semi-cylindrical structure constitutes the bottom of the housing, and the grip 5 is an arc-shaped grip, which is arranged along the vertical direction on the rectangular surface of the semi-cylindrical structure.

[0055] Optionally, in one possible implementation, the bow-shaped grip is provided with a wavy soft rubber pad on the side facing the housing 1, which makes it easier for the operator to grip the bow-shaped grip.

[0056] Specifically, the overall shape of the housing 1 resembles a semi-cylindrical structure, consisting of an upper semi-circular portion, a lower semi-circular portion, a rectangular surface, and an arc-shaped surface. The upper semi-circular portion forms the top of the housing 1, and a receiving groove 11 is provided on it. The bottom surface of the receiving groove 11 has a hole for the suction tube 3 to pass through, allowing the suction tube 3 to be inserted into the housing 1. Furthermore, a grip portion 5 is provided on one side of the rectangular surface. This grip portion 5 can be an arc-shaped grip portion to fit the hand, making it convenient for the operator to wear the device. A locking groove 12 is provided near the bottom of the arc-shaped surface. This locking groove 12 can be used to lock the ultrasonic equipment, preventing collisions and damage to the ultrasonic probe of the ultrasonic equipment.

[0057] It should be noted that, see Figure 1 The receiving groove 11 is connected to one side of the arc-shaped surface of the semi-cylindrical structure, but not to one side of the rectangular surface. That is, after the limit switch 4 is opened, the nozzle assembly 2 can be tilted away from the rectangular surface and towards the side of the arc-shaped surface. The part that exceeds the space of the receiving groove 11 can also be suspended on the outside of the arc-shaped surface, which is very convenient for users to operate.

[0058] For further details, please refer to [link / reference]. Figure 2The bottom of the box is provided with a liquid inlet (not shown in the figure), which passes through the bottom part of the box. Correspondingly, the ultrasonic coupling agent spraying device provided in this application also includes a cover 6, which covers the liquid inlet.

[0059] Specifically, when it is necessary to add ultrasonic coupling agent to the inside of the chamber, the cover 6 can be pulled out and the ultrasonic coupling agent can be added to the inside of the chamber through the liquid filling port; after the task of adding ultrasonic coupling agent is completed, the cover 6 can be inserted back into the liquid filling port to prevent the ultrasonic coupling agent from leaking out through the liquid filling port.

[0060] Alternatively, in one possible implementation, please refer to [link / reference]. Figure 2 and Figure 3 The cover 6 includes a rotating handle 61 and a rotating post 62, wherein the rotating post 62 and the rotating handle 61 are vertically connected; wherein,

[0061] When the cover 6 is placed over the liquid filling port, the rotating column 62 extends into the liquid filling port, and the rotating handle 61 is exposed outside the box 1 in a manner parallel to the bottom surface of the box 1.

[0062] Specifically, the rotating handle 61 is horizontally positioned, and the rotating column 62 is vertically positioned, with the two connected vertically. By connecting the rotating column 62 and the rotating handle 61, a cover 6 is formed. By inserting the rotating column 62 into the liquid filling port, the cover 6 can be placed on the liquid filling port. When the cover 6 is placed on the liquid filling port, the rotating column 62 extends into the inside of the box, while the rotating handle 61 is exposed at the bottom of the box 1. This allows the operator to easily pull out the entire cover 6 by rotating the handle 61 to add ultrasonic coupling agent into the box 1.

[0063] The ultrasonic coupling agent spraying device provided in this embodiment has a semi-cylindrical structure. The upper semi-circular part forms the top, which has a receiving groove for installing the nozzle assembly, allowing the nozzle assembly to flexibly switch states within the receiving groove. The lower semi-circular part forms the bottom, with a slot designed on one side of the arc-shaped surface for engaging with the ultrasonic equipment, thereby ensuring the stability and reliability of the equipment during operation. In addition, one side of the rectangular surface has an ergonomically designed arched grip with a wavy soft rubber pad on its surface to improve the operator's grip comfort.

[0064] To facilitate the addition of ultrasonic coupling agent, the bottom of the chamber is designed with a filling port and a cover. The cover consists of a rotating handle and a rotating column. Operators can easily install and remove the cover by rotating the handle to insert or remove the rotating column from the filling port. When adding ultrasonic coupling agent, simply remove the cover, add the agent to the chamber through the filling port, and then replace the cover to prevent leakage. This design not only improves operational convenience and grip comfort but also effectively enhances the spraying efficiency of the ultrasonic coupling agent.

[0065] Furthermore, to control the state of the nozzle assembly 2, a limit switch 4 is installed on the top of the housing 1. This limit switch 4 is positioned on the receiving groove 11, spanning both sides of the receiving groove 11. Thus, during operation, the limit switch 4 can limit the nozzle assembly 2 to the vertical direction. Figure 2 As shown, the nozzle assembly 2 is positioned vertically. When finishing work, the limit switch 4 can be opened, allowing the nozzle assembly 2 to move along the internal space of the receiving groove 11. The operator can then manipulate the nozzle assembly 2 to switch it from a vertical to a horizontal position. Once the nozzle assembly 2 is in a horizontal position, the limit switch 4 is closed again to limit its horizontal position. In other words, in the non-working state, the nozzle assembly 2 is stored in the receiving groove 11, preventing interference during ultrasonic testing and obstruction during high-altitude climbing operations.

[0066] Figure 4 This is a top view of an ultrasonic coupling agent spraying apparatus suitable for special equipment, as shown in an exemplary embodiment of this application. Please refer to... Figure 4 In one possible implementation, the limit switch 4 includes a first fixing member 41, a rotating shaft 42, and a second fixing member 43;

[0067] The first end of the rotating shaft 42 is a fixed end, and the second end of the rotating shaft is a movable end. The first end is rotatably connected to the first fixing member 41, and the movable end can be selectively connected to the second fixing member 43.

[0068] The first fixing member 41 is fixed to one side of the receiving groove 11, and the second fixing member 43 is fixed to the opposite side of the receiving groove 11;

[0069] When the movable end is not connected to the second fixing member 43, the nozzle assembly 2 can freely switch between a horizontal state and a vertical state;

[0070] When the nozzle assembly 2 is in a horizontal state, the movable end is fixedly connected to the second fixing member 43 to limit the nozzle assembly 2 to a horizontal state; when the nozzle assembly 2 is in a vertical state, the movable end is fixedly connected to the second fixing member 43 to limit the nozzle assembly 2 to a vertical state.

[0071] Specifically, the rotating shaft 42 is the core of the limit switch 4. It is connected to the first fixing member 41 and the second fixing member 43. One end of the rotating shaft 42 is a fixed end, which is movably connected to the first fixing member 41, while the other end is a movable end, which is selectively connected to the second fixing member 43. In this way, when the rotating shaft 42 does not need to move, the movable end can be kept connected to the second fixing member 43, so that the limit switch 4 maintains its limiting function and restricts the movement of the nozzle assembly 2. When the rotating shaft 42 needs to move, the movable end can be separated from the second fixing member 43. Through the movable connection between the fixed end and the first fixing member 41, the rotating shaft 42 can be moved, so that the rotating shaft 42 rotates within a certain range, thereby moving the nozzle assembly 2 and changing its state.

[0072] The ultrasonic coupling agent spraying device provided in this embodiment, through the cooperation between the rotating shaft, the first fixing member, and the second fixing member, allows the movable end to be connected to the second fixing member when the nozzle assembly is in a horizontal or vertical state, restricting the rotation of the nozzle assembly and ensuring its stability. When it is necessary to change the state of the nozzle assembly, the limiting can be released through the movable rotating shaft, allowing the nozzle assembly to switch between horizontal and vertical states. In this way, the precise positioning and limiting function of the nozzle assembly can be achieved, improving the ease of use of the ultrasonic coupling agent spraying device and the convenience of placement when not in use.

[0073] Please refer to the following at the same time Figure 2 The upper side of the suction pipe 3 is connected to the nozzle assembly 2, and the lower side of the suction pipe 3 is inserted into the box 1 to draw ultrasonic coupling agent from inside the box 1. In this way, when the ultrasonic coupling agent spraying device is working, the ultrasonic coupling agent inside the box can be drawn into the nozzle assembly 2 through the suction pipe 3, and then sprayed to the required position through the nozzle assembly 2.

[0074] It should be noted that by setting a receiving groove and a limit switch on the top of the housing, the nozzle assembly is installed inside the receiving groove. By controlling the opening and closing of the limit switch, the nozzle assembly can be controlled to be in a vertical state when working or a horizontal state when not working. Furthermore, by installing a grip on the other side of the receiving groove in the housing, when the operator needs to perform the spraying operation, he can hold the grip and use his thumb to control the opening and closing of the limit switch and the switching of the nozzle assembly's state. This design not only facilitates the operator's spraying operation, but also allows the ultrasonic coupling agent spraying device to be set to a horizontal state when it is not needed, thus facilitating the placement of the ultrasonic coupling agent spraying device.

[0075] Optional, please continue to refer to Figure 2 and Figure 3In one possible implementation, the nozzle assembly 2 includes a liquid reservoir 21, a push button 22, a valve body 23, a spring 24, and a nozzle 25;

[0076] The liquid storage tank 21 is provided with a drive chamber 211 and a liquid storage chamber 212 that are connected in a vertical direction; the bottom of the liquid storage chamber 212 is connected to the suction pipe 3.

[0077] The nozzle 25 is disposed on the side wall of the liquid storage tank 21 and communicates with the liquid storage cavity 212;

[0078] The button 22 includes a pressing part 221 and an extension part 222; the pressing part 221 is located on the outside of the liquid storage tank 21, and the extension part 222 extends vertically into the drive cavity 211.

[0079] The valve body 23 includes a ring sleeve 231 and a piston rod 232 fixed on the ring sleeve 231; the ring sleeve 231 is slidably disposed in the drive chamber 211, the upper end of the piston rod 232 is connected to the extension part 222, and the lower end extends downward to the liquid storage chamber 212; the first end of the spring 24 is fixed to the bottom of the ring sleeve 231, and the second end of the spring 24 is fixed to the bottom of the drive chamber 211, so that the valve body 23 is in a pre-compression state;

[0080] When the external force presses the button 22, the extension part 222 drives the piston rod 232 to move downward, so that the liquid in the liquid storage chamber 212 is discharged through the nozzle 25; after the external force is released, the spring elastically recovers, pushing the valve body 23 and the button 22 back to their original positions, thereby completing one press-to-discharge cycle.

[0081] Figure 5 This is a partial schematic diagram of a nozzle assembly shown in an exemplary embodiment of this application. Please refer to... Figure 5 The liquid storage tank 21 can be a one-piece molded structure, with a drive cavity 211 and a liquid storage cavity 212 inside, which are connected in the vertical direction.

[0082] Specifically, when the operator uses the ultrasonic coupling agent spraying device, the valve body 23 can be controlled by pressing the button 22. When the ultrasonic coupling agent spraying device needs to be used for spraying, the operator can press the button 22. At this time, the pressing part 221 and the extending part 222 move downward together, thereby pushing the piston rod 232 inside the drive chamber 211. The ring sleeve 231 is fitted on the lower side of the protrusion of the piston rod 232. As the piston rod 232 moves downward, it drives the ring sleeve 231 to move downward as well. Furthermore, the downward moving ring sleeve 231 compresses the spring 24 located below the ring sleeve 231. At this time, due to the downward moving piston rod 232, the gas inside the liquid storage chamber 212 is compressed. Compression increases the internal air pressure, making it greater than the external atmospheric pressure. This pressure difference drives the ultrasonic coupling agent to flow into the storage chamber 212 through the suction tube 3 and then spray it out through the nozzle 25. After completing the designated spraying operation, the operator stops pressing the button 22. At this time, the pressing part 221 is no longer subjected to downward pressure, and due to the elastic recovery effect of the spring 24, the ring 231 is pushed back to its original position, so that the pressure inside the ultrasonic coupling agent spraying device returns to the same level as the external atmospheric pressure. As the ring 231 returns to its original position, the pressing part 221 and the extension part 222 in the button 22 also return to their original positions, waiting for the next pressing operation.

[0083] The ultrasonic coupling agent spraying device provided in this embodiment uses a button to control the valve body, thereby achieving the spraying of coupling agent driven by the internal and external pressure difference. When the operator presses the button, the piston rod moves the ring sleeve downward, compressing the internal gas and increasing the air pressure in the cavity, causing the ultrasonic coupling agent to flow into the storage cavity through the suction tube and finally be sprayed out through the nozzle. After releasing the button, the restoring force of the spring resets the ring sleeve, stopping the spraying. In this way, the discharge of coupling agent can be controlled by pressing the button, which can effectively and accurately control the spraying amount.

[0084] The working principle of the ultrasonic coupling agent spraying device provided in this application is illustrated below:

[0085] Specifically, before using the ultrasonic coupling agent spraying device to perform the spraying operation, the operator holds the grip and lifts the ultrasonic coupling agent spraying device, and then separates the movable end of the rotating shaft in the limit switch from the second fixing part. At this point, the operator can freely rotate the nozzle assembly to change it from a horizontal to a vertical position. Then, the fixed end of the rotating shaft is reconnected to the second fixing component, thus restricting the position of the nozzle assembly and ensuring it remains stably in the set vertical position, ready for ultrasonic coupling agent spraying. Next, the operator presses the button with their thumb, causing the pressing part and the extending part of the button to move downwards together, pushing the piston rod inside the valve body. This compresses the gas in the drive chamber, increasing the internal gas pressure of the device. Simultaneously, the ultrasonic coupling agent flows into the storage chamber through the suction tube and, under the action of the internal and external pressure difference, is sprayed out through the nozzle, completing the ultrasonic coupling agent spraying operation. After completing the spraying task, the operator releases the button. The restoring force of the spring returns the button to its original position, and the valve body resets, stopping gas compression, disconnecting the spraying channel, and stopping the spraying of the ultrasonic coupling agent. This completes one spraying operation of the ultrasonic coupling agent spraying device. Furthermore, after the spraying is completed, the fixed end of the rotating shaft is separated from the second fixing component, and the operator rotates the nozzle assembly to change it from a vertical state during spraying to a horizontal state. Then, the fixed end of the rotating shaft is reconnected to the second fixing component, thereby restricting the position of the nozzle assembly and ensuring that it can remain in the set horizontal state when not spraying, making it easy to place.

[0086] The ultrasonic coupling agent spraying device for special equipment provided in this embodiment can be worn on the back of the finger for easy carrying and testing. The activation and retraction of the nozzle assembly can be conveniently controlled by sliding the top limit switch with the thumb, thereby preventing interference from the nozzle assembly during ultrasonic testing and obstruction during high-altitude climbing operations. Furthermore, pressing the top button with the thumb can effectively squeeze out the internal ultrasonic coupling agent and evenly apply it to the area to be tested, thus significantly improving testing efficiency and safety.

[0087] In addition, the ultrasonic equipment can be suspended on the side of the enclosure during the application of the coupling agent to prevent damage to the probe. This eliminates the need for frequent replacement of the ultrasonic equipment and the ultrasonic coupling agent spraying device, greatly improving detection efficiency and safety.

[0088] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
