Description
Technical Field
[0001] This utility model relates to the field of vacuum valve box technology, specifically to a valve box for vacuum purging of tank car pipes. Background Technology
[0002] The tank truck pipe blowing vacuum valve box is a piece of equipment used for tank truck pipeline operations. The vacuum valve box is the core component, integrating various valves and control components. Through equipment such as vacuum pumps, it can achieve vacuuming of the tank truck pipeline, reduce the internal air pressure, facilitate efficient loading and unloading of materials, and also has the function of introducing compressed air to purge the pipeline, which can remove residual materials and impurities, ensuring the safe and smooth operation of tank truck operations.
[0003] Existing technologies often have the following problems when used: In the vacuum operation of tank truck pipe purging, the valve box is a key piece of equipment. The glass observation window on its door is used by operators to observe the working status of the internal sensors and instruments in real time. However, in actual use, the inside of the glass observation window of the existing valve box is prone to water vapor accumulation, which reduces the light transmittance and visibility of the glass observation window. This makes it impossible for operators to accurately observe the internal condition of the valve box in a timely manner without opening the door, affecting the safety and efficiency of the vacuum operation of tank truck pipe purging. Utility Model Content
[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a valve box for vacuum purging of tank truck pipes, which can effectively solve the problem that the inner side of the glass observation window on the valve box is prone to water vapor adhesion, resulting in reduced light transmittance and visibility, making it impossible for operators to observe the internal situation in a timely and accurate manner without opening the box door, thus affecting the safety and efficiency of vacuum purging of tank truck pipes.
[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a valve box for vacuum purging of tank truck pipes, comprising: The valve box body has a door rotatably installed on its side wall, and a glass observation window is provided on the door; An automatic cleaning assembly includes two transverse guide rails fixedly connected to the inner wall of the door, concave brackets slidably connected within the two transverse guide rails, a rotating shaft rotatably connected to the end of the concave brackets, a sponge roller fixedly connected to the outer peripheral wall of the rotating shaft, the sponge roller engaging with the glass observation window, a trigger drive component fixedly installed on the inner wall of the valve box body, the trigger drive component automatically driving the sponge roller to move according to the light transmittance of the glass observation window, and two self-draining components fixedly connected to the inner wall of the door, the two self-draining components being equidistantly distributed on both sides of the glass observation window, the self-draining components being used to automatically drain the water absorbed by the sponge roller.
[0006] Furthermore, the triggering drive component includes a vision sensor fixedly installed on the inner wall of the valve box body. The vision sensor is used to monitor the light transmittance of the glass observation window in real time. An electric linear actuator is fixedly installed on the inner wall of the box door. The telescopic end of the electric linear actuator is fixedly connected to a concave bracket. A PLC controller is fixedly installed on the outer wall of the box door. The PLC controller, the electric linear actuator, the vision sensor, and an external power supply are electrically connected.
[0007] Furthermore, the automatic cleaning assembly also includes two transmission gears fixedly connected to the two ends of the rotating shaft, and two toothed plates fixedly connected to the inner wall of the door, with the two transmission gears meshing with the two toothed plates respectively.
[0008] Furthermore, the self-draining component includes several elastic bending plates fixedly connected to the inner wall of the box door, and abutment plates are fixedly connected to the ends of the elastic bending plates away from the box door. The abutment plates are arranged in a concave structure, and the sponge roller selectively squeezes and engages with the abutment plates.
[0009] Furthermore, a drainage through hole is provided at the bottom end of the valve box body.
[0010] Furthermore, an opening and closing handle is fixedly installed on the outer wall of the box door.
[0011] The technical solution provided by this utility model has the following advantages compared with the known prior art: This invention incorporates an automatic cleaning component. A visual sensor monitors the light transmittance of the glass observation window. Low light transmittance indicates excessive moisture on the inner surface. The sensor transmits the detected signal to a PLC controller, which then activates an electric linear actuator. This actuator's extension and retraction drive a concave bracket and a sponge roller to move horizontally, allowing the sponge roller to conform to the glass observation window. Simultaneously, it drives a rotating shaft, enabling the sponge roller to roll and press against the glass observation window, thus adsorbing moisture from the inner surface and preventing it from affecting light transmittance and visibility. This automatic cleaning allows operators to accurately observe the valve box's interior, ensuring the safety and efficiency of the tank truck pipe purging vacuum operation. Furthermore, a self-draining component is included. As the sponge roller moves, it also rolls against a pressure plate, which squeezes the roller, automatically expelling any moisture adsorbed inside. This maintains the sponge roller's moisture adsorption performance and ensures effective cleaning of the glass observation window. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0015] The present invention will be further described below with reference to the embodiments.
[0016] Example: Refer to Figures 1 to 4A valve box for vacuum purging of tank truck pipes includes: a valve box body 1 and an automatic cleaning assembly. A door 2 is rotatably mounted on the side wall of the valve box body 1, and an opening / closing handle 16 is fixedly mounted on the outer wall of the door 2. A glass observation window 3 is provided on the door 2. The automatic cleaning assembly includes two transverse guide rails 4 fixedly connected to the inner wall of the door 2. A concave bracket 5 is slidably connected within the two transverse guide rails 4. A rotating shaft 6 is rotatably connected to the end of the concave bracket 5. A sponge roller 7 is fixedly connected to the outer peripheral wall of the rotating shaft 6. The sponge roller 7 is in a pressing fit with the glass observation window 3. A trigger drive component is fixedly mounted on the inner wall of the valve box body 1. The trigger drive component is used to automatically drive the sponge roller 7 to move according to the light transmittance of the glass observation window 3. The trigger drive component includes components fixedly mounted on... The inner wall of the valve box body 1 is equipped with a vision sensor 8, which is used to monitor the light transmittance of the glass observation window 3 in real time. The inner wall of the door 2 is fixedly installed with an electric linear actuator 9, which is a linear servo actuator of model RM-SLA-08-30-1. The telescopic end of the electric linear actuator 9 is fixedly connected to the concave bracket 5. The outer wall of the door 2 is fixedly installed with a PLC controller 10. The PLC controller 10, the electric linear actuator 9, and the vision sensor 8 are electrically connected to an external power supply. The automatic cleaning component also includes two transmission gears 11 fixedly connected to the two ends of the rotating shaft 6. The inner wall of the door 2 is fixedly connected with two toothed plates 12, and the two transmission gears 11 mesh with the two toothed plates 12 respectively. The light transmittance of the glass observation window 3 is monitored by a vision sensor 8. If the light transmittance of the glass observation window 3 is low, it indicates that there is a lot of water vapor attached to the inner surface of the glass observation window 3. The vision sensor 8 transmits the monitored signal to the PLC controller 10, which controls the electric linear push rod 9 to start. This allows the telescopic end of the electric linear push rod 9 to drive the concave bracket 5 to move horizontally, so that the sponge roller 7 can move in contact with the glass observation window 3. The meshing of the transmission gear 11 and the toothed plate 12 drives the rotating shaft 6 to rotate, so that the sponge roller 7 can squeeze and roll in contact with the glass observation window 3. This allows the sponge roller 7 to absorb the water vapor on the inner surface of the glass observation window 3, preventing the water vapor from affecting the light transmittance and visibility of the glass observation window 3. This achieves automatic cleaning of the glass observation window 3, allowing operators to observe the internal condition of the valve box in a timely and accurate manner, ensuring the safety and efficiency of the tank truck pipe purging vacuum operation.
[0017] Two self-draining components are fixedly connected to the inner wall of the box door 2. The two self-draining components are equidistantly distributed on both sides of the glass observation window 3. The self-draining components are used to automatically drain the water adsorbed by the sponge roller 7. The self-draining components include several elastic bending plates 13 fixedly connected to the inner wall of the box door 2. The ends of the several elastic bending plates 13 away from the box door 2 are fixedly connected to the abutment plate 14. The abutment plate 14 is set in a concave structure, and the sponge roller 7 and the abutment plate 14 are selectively squeezed together. A drainage through hole 15 is opened at the bottom of the valve box body 1. Specifically, the elastic bending plate 13 is made of polyurethane elastic rubber with a Shore hardness of 60A, which has high elastic recovery performance and can generate continuous extrusion pressure through deformation. The abutment plate 14 is set with a concave structure so that after the sponge roller 7 initially contacts the abutment plate 14, the abutment plate 14 can fully contact and roll with the sponge roller 7 to ensure that the sponge roller 7 is fully drained. When the sponge roller 7 moves, it will also contact and roll with the abutment plate 14. When the sponge roller 7 starts to squeeze the abutment plate 14, it will cause several elastic bending plates 13 to deform and accumulate elastic potential energy. During the rolling process of the sponge roller 7 and the abutment plate 14, several elastic bending plates 13 will push the abutment plate 14 with their own elastic force, so that the abutment plate 14 can squeeze the sponge roller 7, thereby automatically discharging the moisture adsorbed inside the sponge roller 7, which is beneficial to maintaining the water vapor adsorption performance of the sponge roller 7 and ensuring the cleaning power of the glass observation window 3.
[0018] The working principle of this utility model is as follows: During use, the light transmittance of the glass observation window 3 is monitored by the vision sensor 8. If the light transmittance of the glass observation window 3 is low, it indicates that there is a lot of water vapor attached to the inner surface of the glass observation window 3. The vision sensor 8 transmits the monitored signal to the PLC controller 10, which controls the electric linear push rod 9 to start. This allows the telescopic end of the electric linear push rod 9 to drive the concave bracket 5 to move horizontally, so that the sponge roller 7 can move in contact with the glass observation window 3. The meshing of the transmission gear 11 and the toothed plate 12 drives the rotating shaft 6 to rotate, so that the sponge roller 7 can squeeze and roll in contact with the glass observation window 3. This allows the sponge roller 7 to absorb the water vapor on the inner surface of the glass observation window 3, preventing the water vapor from affecting the light transmittance and visibility of the glass observation window 3. This achieves automatic cleaning of the glass observation window 3, allowing operators to observe the internal condition of the valve box in a timely and accurate manner, ensuring the safety and efficiency of the tank truck pipe purging vacuum operation. When the concave support 5 and the sponge roller 7 move horizontally, the sponge roller 7 will also roll in contact with the abutment plate 14. When the sponge roller 7 starts to squeeze the abutment plate 14, it will cause several elastic bending plates 13 to deform and accumulate elastic potential energy. During the rolling process of the sponge roller 7 and the abutment plate 14, several elastic bending plates 13 will push the abutment plate 14 with their own elastic force, so that the abutment plate 14 can squeeze the sponge roller 7, thereby automatically discharging the moisture adsorbed inside the sponge roller 7, which is beneficial to maintaining the water vapor adsorption performance of the sponge roller 7 and ensuring the cleaning power of the glass observation window 3.
