Description

Technical Field

[0001] The utility model relates to the technical field of pressure difference monitors, and particularly relates to a waterproof and dustproof pressure difference monitor. Background Technique

[0002] In the storage, transportation and other operations of liquefied petroleum gas, most enterprises adopt relatively primitive monitoring means, resulting in low statistical efficiency. Therefore, it is necessary to detect and monitor pipelines through a series of devices such as pressure sensors, oscilloscopes, and logic analyzers.

[0003] For example, the disclosed document with the application number 202221127959.8 discloses a dangerous liquid pressure monitor. The utility model is threadedly connected through bolts and screw holes one, two and thread grooves one, so that the connecting piece is fixed. By rotating the knob, the threaded rod drives the arc plate to slide relatively. Through the elastic force of the spring, the rubber plate is tightly attached to the liquid pipeline, realizing the clamping and fixing of the liquid pipeline, greatly improving the installation stability. However, for this pressure difference monitor, in the monitor, when detecting externally through a transmission line connected to an external device, a wiring socket will be left for effective and convenient data transmission. Since the socket always remains open, dust and water vapor will enter the interior, causing damage to the internal sensor components and resulting in the failure of the entire monitor, affecting the normal use of the monitor.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a waterproof and dustproof pressure difference monitor is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a waterproof and dustproof pressure difference monitor to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A waterproof and dustproof pressure difference monitor, including sensor pins, a control box is fixedly arranged at the top of the sensor pins, a sealing door is rotatably arranged on the front side of the control box, a rubber leather sleeve is fixedly arranged on the surface of the sealing door, a wiring mechanism is arranged on the left side of the surface of the control box, and a fixing member is installed on the surface of the sensor pins.

[0007] Preferably, sensor components and control components are assembled inside the control box, and the rubber leather sleeve corresponds to the buttons on the surface of the control components.

[0008] Preferably, the wiring mechanism includes a socket fixedly installed on the left side of the outer surface of the control box, and the socket corresponds to the wiring port of the sensor components.

[0009] Preferably, the wiring mechanism further includes sunk grooves correspondingly formed on the left and right sides of the inner surface of the socket. A thrust spring is fixedly installed on the inner surface of the sunk groove. One end of the thrust spring is fixedly installed with a rubber sleeve movable plate, and the rubber sleeve movable plate is rotatably connected to the front side of the inner surface of the socket.

[0010] Preferably, the fixing member includes a support plate rotatably installed below the surface of the sensor pin. Bolts are threadedly penetrated through the lower left and right sides of the surface of the support plate.

[0011] Preferably, the fixing member further includes a clamping plate rotatably installed at the opposite ends of the bolts. An arc groove is formed on the opposite side of the surface of the clamping plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the settings of the control box, the sealing door and the rubber leather sleeve in the present utility model, the control box and the sealing door form a complete sealed housing to encapsulate various electrical components of the monitor, thereby preventing the electrical components from contacting the outside world, effectively preventing dust and water vapor from entering, and the rubber leather sleeve can accurately control the monitor without opening the sealing door, further preventing dust from entering the control box and avoiding damage to the electrical components.

[0014] 2. Through the settings of the wiring mechanism, the socket, the sunk groove, the thrust spring and the rubber sleeve movable plate in the present utility model, in the case of no transmission line connected, the thrust spring pushes the rubber sleeve movable plates to horizontally fit with each other to block the channel of the socket, effectively preventing dust and water vapor from entering the interface inside of the sensor component through the socket and avoiding damage to the entire monitor. After the transmission line is connected, the thrust spring pushes the rubber sleeve movable plate to closely adhere to the surface of the transmission line, causing the rubber sleeve movable plate to no longer be able to rotate, and the rotational force received will be converted into a clamping force on the transmission line. The greater the pulling force, the greater the clamping force, making the connection between the transmission line and the monitor extremely stable, ensuring the stability of real-time data transmission, and thus improving the monitoring accuracy.

[0015] 3. Through the settings of the fixing member, the support plate, the bolts, the clamping plate and the arc groove in the present utility model, after the monitor is assembled with the pipeline using the sensor pin, then adjust the angle of the clamping plate to make the arc groove match the pipeline. Then, rotate the bolts so that the clamping plate clamps the pipeline through the arc groove, thereby making the installation of the entire monitor more stable and avoiding the monitor from loosening and falling off.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 - 3 shown, a waterproof and dustproof pressure difference monitor includes a sensor pin 1. A control box 2 is fixedly arranged at the top end of the sensor pin 1. A sealing door 3 is rotatably arranged on the front side of the control box 2. A rubber sheath 4 is fixedly arranged on the surface of the sealing door 3. A wiring mechanism 5 is arranged on the left side of the surface of the control box 2. A fixing member 6 is installed on the surface of the sensor pin 1. Sensor components and control components are assembled inside the control box 2, and the rubber sheath 4 corresponds to the buttons on the surface of the control components.

[0022] By adopting the above technical solution, the control box 2 and the sealing door 3 form a complete sealed housing to encapsulate various electrical components of the monitor, thereby preventing the electrical components from contacting the outside world; the rubber sheath 4 can accurately control the monitor without opening the sealing door 3, further preventing dust from entering the control box 2 and avoiding damage to the electrical components.

[0023] Further, the wiring mechanism 5 includes a socket 501 fixedly installed on the left side of the outer surface of the control box 2, and the socket 501 corresponds to the wiring port of the sensor component.

[0024] By adopting the above technical solution, the transmission line can be connected to the sensor component through the socket 501.

[0025] Further, the wiring mechanism 5 further includes sink grooves 502 correspondingly opened on the left and right sides of the inner surface of the socket 501. A thrust spring 503 is fixedly installed on the inner surface of the sink groove 502. One end of the thrust spring 503 is fixedly installed with a rubber sleeve movable plate 504, and the rubber sleeve movable plate 504 is rotatably connected to the front side of the inner surface of the socket 501.

[0026] By adopting the above technical solution, in the case of no connection of the transmission line, the thrust spring 503 pushes the rubber sleeve moving plates 504 to fit horizontally with each other, blocking the channel of the socket 501 and effectively preventing dust and moisture from entering the interface of the sensor components through the socket 501;

[0027] After the transmission line is connected through the socket 501, the thrust spring 503 pushes the rubber sleeve moving plates 504 to closely adhere to the surface of the transmission line. When the transmission line is pulled outward, due to the friction between the rubbers, the rubber sleeve moving plates 504 will also be driven to rotate forward. However, the transmission line occupies a certain internal space of the socket 501, resulting in the inability of the rubber sleeve moving plates 504 to continue rotating. The rotational force received will be converted into a clamping force on the transmission line. The greater the pulling force, the greater the clamping force, making the connection between the transmission line and the monitor extremely stable.

[0028] Furthermore, the fixing member 6 includes a support plate 601 rotatably installed below the surface of the sensor pin 1, and bolts 602 are threadedly penetrated and connected to the lower sides of the left and right sides of the surface of the support plate 601.

[0029] By adopting the above technical solution, the support plate 601 rotates, and the positions of the bolts 602 can be adjusted according to the pipeline direction.

[0030] Furthermore, the fixing member 6 further includes a clamping plate 603 rotatably installed at the opposite ends of the bolts 602, and an arc groove 604 is formed on the opposite side of the surface of the clamping plate 603.

[0031] By adopting the above technical solution, the arc groove 604 can match the outer shape of the pipeline, making the clamping plate 603 more closely adhere to the pipeline during clamping.

[0032] Working principle: When using this waterproof and dustproof pressure difference monitor, first, install the monitor on the pipeline, then adjust the angle of the clamping plate 603 so that the arc groove 604 matches the pipeline. Then, rotate the bolt 602 so that the clamping plate 603 clamps the pipeline through the arc groove 604. The control box 2 and the sealing door 3 form a complete sealed housing to encapsulate various electrical components of the monitor. The monitor can be precisely controlled through the rubber sheath 4. After the entire monitor is installed, the transmission line is plugged and installed according to requirements. In the case where the transmission line is not connected, the thrust spring 503 pushes the rubber sleeve movable plate 504 to fit horizontally with each other, blocking the channel of the socket 501, effectively preventing dust and water vapor from entering the interface inside the sensor components through the socket 501. When the transmission line is connected through the socket 501, the thrust spring 503 pushes the rubber sleeve movable plate 504 to closely adhere to the surface of the transmission line. When the transmission line is pulled outward, due to the friction between the rubbers, the rubber sleeve movable plate 504 will also be driven to rotate forward. However, the transmission line occupies a certain internal space of the socket 501, resulting in the rubber sleeve movable plate 504 being unable to continue rotating. The rotational force received will be converted into a clamping force on the transmission line. The greater the pulling force, the greater the clamping force, making the connection between the transmission line and the monitor extremely stable and ensuring the stability of real-time data transmission. This is the working principle of this waterproof and dustproof pressure difference monitor.
