Description

Technical Field

[0001] This utility model relates to the field of storage tank liquid level detection technology, specifically a multi-sensor fusion chemical storage tank liquid level early warning device. Background Technology

[0002] Storage tanks and other containers are frequently used in chemical production, and these tanks are often kept closed during use. In order to know the liquid level of the liquid material in the tank without opening it, or to automatically detect the liquid level in the tank to prevent overflow, a liquid level warning device is needed to provide early warning of the liquid level in the tank.

[0003] Currently, in order to automatically warn of the liquid level in storage tanks, sensors are generally used to detect the liquid level, such as ultrasonic sensors. These sensors have high detection accuracy. However, because the storage tanks are relatively humid, the humid environment accelerates the aging of the sensors, requiring regular opening and maintenance. To improve maintenance efficiency, a multi-sensor fusion-based chemical storage tank liquid level early warning device is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a multi-sensor fusion-based early warning device for liquid level in chemical storage tanks, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a multi-sensor fusion-based chemical storage tank level early warning device, comprising a tank body, a positioning block fixedly connected to the top of the tank body, and an installation assembly on the tank body. The installation assembly is used to install an ultrasonic sensor and a level detection component, and includes:

[0006] A connecting component, which is disposed on the tank body;

[0007] The mounting plate is disposed below the connecting assembly, and a sealing sleeve is embedded in the outer wall of the mounting plate.

[0008] Preferably, the connecting assembly includes a connecting seat, a rotating ring rotatably connected to the inner wall of the connecting seat, a T-rod fixedly connected to the upper side of the rotating ring, the rotating ring being elastically connected to the top inner wall of the connecting seat via a spring, a hinge rod hinged to the rotating ring, a sliding plate hinged to the end of the hinge rod away from the rotating ring, and an insert block fixedly connected to the side of the sliding plate away from the hinge rod. By rotating the T-rod, the rotating ring is driven to rotate, which in turn drives the hinge rod to move, causing the sliding plate to slide in the inner wall of the connecting seat, thereby driving the insert block to move. After releasing the T-rod, the rotating ring can be reset by the reset action of the spring.

[0009] Preferably, the connecting seat is fixed to the mounting plate, and a positioning groove is provided on the outer wall of the connecting seat, which matches the positioning block.

[0010] Preferably, the positioning block has an insertion port on the side near the mounting component.

[0011] Preferably, the plug is matched with the socket, and after the plug is removed from the socket, the limiting fixation of the connector can be released, making it easy to remove the ultrasonic sensor and the contact sensor for maintenance.

[0012] Preferably, the liquid level detection assembly includes a vertical rod, which is fixedly mounted on a mounting plate. A contact sensor is fixedly connected to the bottom of the vertical rod. A sleeve rod is detachably connected to the lower side of the mounting plate by bolts. A guide rod is fixedly connected to the bottom of the sleeve rod. A limit ring is fixed on the guide rod. The guide rod passes through a float and is slidably connected to the float. As the liquid level rises, the float floats upward. When the float comes into contact with the contact sensor, a liquid level warning is triggered.

[0013] Preferably, the sleeve rod has through holes on both its side wall and bottom, and the diameter of the through hole on the side wall is smaller than the diameter of the through hole on the bottom. In this way, the impact resistance is reduced, which can reduce the impact on the float when the liquid shakes a lot.

[0014] This invention provides a multi-sensor fusion-based early warning device for liquid level in chemical storage tanks. It offers the following advantages:

[0015] (1) The multi-sensor fusion chemical storage tank liquid level early warning device uses the connecting components. By rotating the T rod, the plug can be disengaged from the socket of the positioning block, and the limiting fixation of the connecting seat can be quickly released. The mounting plate, ultrasonic sensor, contact sensor and other components can be disassembled as a whole. Compared with the traditional chemical storage tank liquid level detection device that requires opening the cover for maintenance, this design realizes modular quick disassembly of the detection components, shortens maintenance time, reduces maintenance difficulty and labor costs, and reduces the impact of maintenance on the normal operation of the storage tank.

[0016] (2) The multi-sensor integrated chemical storage tank liquid level early warning device uses a float to contact the sensor at the bottom of the vertical rod as the liquid level rises to trigger an early warning. The special through-hole design of the sleeve rod reduces the interference of liquid sloshing and ensures the stability of the float movement and the accuracy of the early warning. At the same time, the ultrasonic sensor can monitor the liquid level in real time, which not only makes up for the possible errors of a single sensor, but also provides liquid level monitoring when the contact sensor fails, achieving dual protection. The two detection methods complement each other, improve the reliability and timeliness of liquid level early warning, and effectively avoid safety accidents caused by abnormal liquid levels in chemical storage tanks.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 This utility model proposes a multi-sensor fusion chemical storage tank liquid level early warning device, including a tank body 1, a positioning block 2 fixedly connected to the top of the tank body 1, and an installation component 3 provided on the tank body 1. The installation component 3 is used to install an ultrasonic sensor 4 and a liquid level detection component 5.

[0032] In this embodiment of the invention, to provide dual early warning for liquid level, the liquid level detection component 5 specifically includes a vertical rod 51, which is fixedly mounted on a mounting plate 32. A contact sensor 52 is fixedly connected to the bottom of the vertical rod 51. A sleeve rod 53 is detachably connected to the lower side of the mounting plate 32 via bolts. A guide rod 55 is fixedly connected to the bottom of the sleeve rod 53, and a limit ring 56 is fixed on the guide rod 55. The guide rod 55 passes through a float 57 and is slidably connected to the float 57. Through holes 54 are provided on both the side wall and the bottom of the sleeve rod 53, with the diameter of the through hole 54 on the side wall being smaller than the diameter of the through hole 54 on the bottom. During the process of the liquid level rising, the guide rod 55... Guided by rod 55, float 57 floats upward. When float 57 comes into contact with contact sensor 52, liquid level warning is achieved. Furthermore, the use of sleeve rod 53 and through hole 54 reduces impact resistance when the liquid is agitated significantly, thus minimizing the impact of agitation on float 57. Simultaneously, ultrasonic sensor 4 can monitor the liquid level in real time, compensating for potential errors from a single sensor and providing liquid level monitoring even when contact sensor 52 fails, thus achieving dual protection. The two detection methods complement each other, improving the reliability and timeliness of liquid level warning and effectively preventing safety accidents caused by abnormal liquid levels in chemical storage tanks.

[0033] Furthermore, in order to maintain the ultrasonic sensor 4 and the contact sensor 52, specifically, the mounting assembly 3 includes a connecting assembly 31 and a mounting plate 32. The connecting assembly 31 is mounted on the tank body 1, and the mounting plate 32 is located below the connecting assembly 31. A sealing sleeve 33 is embedded in the outer wall of the mounting plate 32. The connecting assembly 31 includes a connecting seat 311, and a rotating ring 312 is rotatably connected to the inner wall of the connecting seat 311. A T-rod 313 is fixedly connected to the upper side of the rotating ring 312. The rotating ring 312 and the top inner wall of the connecting seat 311 are elastically connected by a spring. A hinge rod 314 is hinged to the rotating ring 312. A sliding plate 315 is hinged to the end of the hinge rod 314 away from the rotating ring 312. The sliding plate 315 is hinged to the end away from the hinge rod 314. A plug 316 is fixedly connected to the side. The positioning block 2 has a socket 21 on the side near the mounting component 3. The plug 316 matches the socket 21. By rotating the T rod 313, the rotating ring 312 is rotated, which in turn drives the hinge rod 314 to move, so that the sliding plate 315 slides in the inner wall of the connecting seat 311, which in turn drives the plug 316 to move. After the T rod 313 is released, the rotating ring 312 can be reset under the reset action of the toggle spring. When the plug 316 is disengaged from the socket 21 of the positioning block 2, the limiting fixation of the connecting seat 311 can be quickly released, and the mounting plate 32, ultrasonic sensor 4, contact sensor 52, etc. can be disassembled as a whole, which shortens the maintenance time, reduces the maintenance difficulty and labor cost, and reduces the impact of maintenance on the normal operation of the storage tank.

[0034] Furthermore, the connecting seat 311 is fixed to the mounting plate 32. A positioning groove is provided on the outer wall of the connecting seat 311. The positioning groove matches the positioning block 2. By using the positioning groove and the positioning block 2, it is convenient to position and install the mounting component 3.

[0035] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0036] During use, as the liquid level rises, the float 57 floats upward under the guidance of the guide rod 55. When the float 57 comes into contact with the contact sensor 52, a liquid level warning is triggered. At the same time, the ultrasonic sensor 4 can monitor the liquid level in real time, which not only compensates for the possible errors of a single sensor, but also provides liquid level monitoring even if the contact sensor 52 fails, thus providing dual protection. When maintenance is required for the ultrasonic sensor 4 and the contact sensor 52, the T rod 313 is rotated, which drives the rotating ring 312 to rotate, thereby driving the hinge rod 314 to move. This causes the sliding plate 315 to slide in the inner wall of the connecting seat 311, thereby causing the insert 316 to disengage from the insertion port 21 of the positioning block 2. This allows for quick release of the limiting fixation of the connecting seat 311, and the installation plate 32, ultrasonic sensor 4, and contact sensor 52 to be disassembled as a whole for maintenance.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
