[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example

[0021] In this embodiment, the smart core bucket for preventing abnormal dumping includes: an inner bucket 1, an outer bucket 2 and a control module.

[0022] like Figure 1 As shown, the outer bottom of the inner tub 1 has a recessed portion 11 and a raised portion 12 , and the recessed portion 11 has a first interlocking sensor 11 a .

[0023] The inner bottom of the outer tub 2 has a raised support platform 25, the position and shape of which match the recessed portion 11. The support platform 25 is provided with a second interlock sensor 25a; the position of the second interlock sensor 25a corresponds one-to-one with the position of the first interlock sensor 11a.

[0024] When the inner tub 1 is placed in the outer tub 2 , the recessed portion 11 is placed on the support platform 25 , and the first interlock sensor 11 a and the second interlock sensor 25 a are docked and sensed, thereby determining whether the inner tub 1 is in the outer tub 2 .

[0025] In this embodiment, the second interlock sensor 25a is a signal transmitter, and the first interlock sensor 11a is a signal receiver. When the first interlock sensor 11a receives the signal from the second interlock sensor 25a, the control module determines that the outer barrel 2 is loaded with the inner barrel 1 and activates abnormal tipping detection. If the second interlock sensor 25a does not receive a signal, it means that the inner barrel 1 is not in the outer barrel 2 and the outer barrel 2 is empty. In theory, monitoring its tilt state is unnecessary. Of course, the outer barrel 2 can still be continuously monitored for tilting when idle, but if it is not loaded with chemical products, the tilting state does not need to be alarmed. Of course, the second interlock sensor 25a can be both a signal transmitter and a signal receiver, while the first interlock sensor 11a is a signal reflector.

[0026] In this embodiment, the raised portion 12 of the inner tub 1 forms a concentric circle with the bottom of the inner tub 1; the first interlock sensor 11a is located at the center of this concentric circle. The support platform 25 is circular, matching the raised portion 12, and the second interlock sensor 25a is located at the center of the support platform 25. This way, when the inner tub 1 is placed into the outer tub 2, there's no need to check the positions of the first and second interlock sensors; they naturally align. Otherwise, an alignment mechanism between the inner and outer tubs would be necessary.

[0027] The inner drum 1 has a lifting lug 15 on its upper portion. When the chemical solution inside the inner drum 1 needs to be dumped during production, the production equipment hooks the lifting lug 15 and lifts the inner drum 1 from the outer drum 2. At this time, the first interlock sensor 11a does not receive the signal transmitted by the second interlock sensor 25a, and the control module does not need to monitor the tilt status of the outer drum.

[0028] To prevent the inner tub 1 from tipping over after it has completed its tipping process and before the next filling cycle begins, without being placed in the outer tub 2, thereby preventing the inner tub 1 from tipping over abnormally. Two pressure sensors 12a are installed on the raised portion 12 of the inner tub 1. The height difference H between the support platform and the inner bottom of the outer tub 2 is greater than the height difference h between the recessed portion 11 and the raised portion 12. Thus, when the inner tub 1 is placed in the outer tub 2, there is a gap between the lower portion of the pressure sensors 12a at the bottom of the inner tub 1 and the bottom of the outer tub 2, and the pressure sensors 12a will not receive any pressure signals.

[0029] When the outer drum is placed directly on the ground or on a conveyor surface, and the pressure sensor 12a exceeds the rated pressure, the control module issues a non-compliance alarm. The rated pressure can be set based on the weight of the inner drum 1. When the inner drum 1 is empty and the pressure is below the rated value, no alarm will be issued. However, once the solution is filled, the rated pressure is exceeded, and an alarm will be issued.

[0030] Furthermore, if the inner barrel 1 is not completely emptied during production and the production equipment places the inner barrel 1 directly on the production equipment or on the ground, the control module will issue a non-compliance alarm. This ensures that the inner barrel 1 will not be separated from the outer barrel 2 while still filled with liquid, ensuring safety.

[0031] When inner tub 1 is placed inside outer tub 2, recessed portion 11 rests on support platform 25, and first interlock sensor 11a and second interlock sensor 25a engage and sense each other. The control module receives the information detected by the sensing module and calculates the tilt of outer tub 2. If the tilt of outer tub 2 exceeds the rated tilt, the control module issues an abnormal tipping alarm.

[0032] That is to say, the inner barrel 1 will not be dumped when it is loaded into the outer barrel 2. At this time, it is necessary to monitor in real time whether the outer barrel 2 is accidentally dumped during the movement, and the inner barrel 1 and the outer barrel 2 are in the same state.

[0033] The outer tub 2 is equipped with a sensing module. When the inner tub 1 is placed inside the outer tub 2, the first interlock sensor 11a and the second interlock sensor 25a engage and sense each other. At this point, the control module receives the information detected by the sensing module and calculates the tilt of the outer tub 2. If the tilt of the outer tub 2 exceeds the rated tilt, the control module issues an abnormal tipping alarm.

[0034] In this embodiment, Figure 2 and Figure 3 As shown, outer barrel 2 comprises inner and outer barrel walls 21 and 22. A detection liquid 23 is disposed between these two walls. This circular cross-section maximizes the effective monitoring area of ​​the detection liquid 23 while minimizing the increase in barrel volume. This allows for a more pronounced liquid level during shaking. The detection liquid 23 is a non-reactive liquid selected based on the material of outer barrel 2.

[0035] In addition, at least one waterproof and breathable valve 22a is provided on the outer barrel wall 22, so that the detection liquid 23 is connected to the atmosphere, and the liquid level is in a free state without pressure and rises and falls naturally with the barrel body.

[0036] In this embodiment, the sensing module includes four liquid level transmitters 3, which are evenly distributed around the circumference of the detection liquid in the shape of a ring; of course, a non-uniform distribution state is also possible. The liquid level transmitter 3 can use a magnetostrictive transmitter or a float liquid level transmitter. These two transmitters belong to the existing technology and will not be described in detail. Taking the magnetostrictive transmitter as an example, the lower end of the probe rod of the magnetostrictive transmitter is fixed in the groove at the bottom between the inner barrel wall 21 and the outer barrel wall 22. The magnetic float 31 of the magnetostrictive transmitter fluctuates with the detection liquid 23, so that the liquid level height of the detection liquid 23 at that point can be obtained.

[0037] In this embodiment, the control module can be built into the outer tub 2. The control module can set the coordinate origin and reference plane as needed, with the bottom of the inner tub 1 serving as the reference plane, and its origin serving as the coordinate origin, i.e., (0, 0). The control module stores the position information of each liquid level transmitter 3, namely, the X and Y coordinates. These two coordinates are fixed and unchanging when the magnetostrictive transmitter is installed on the outer tub 2.

[0038] The Z value of the liquid level transmitter 3 changes continuously as the magnetic float 31 rises and falls with the detection liquid 23. If the outer barrel 2 tilts, the magnetic float 31 of the magnetostrictive transmitter at different positions will present different heights. The position of the magnetic float 31 is the height value of the detection liquid 23, that is, the Z coordinate value.

[0039] The liquid level transmitter 3 provides the Z coordinate of the corresponding position to the control module. The control module then obtains the (X, Y, Z) coordinates of each magnetostrictive transmitter at that point in the test liquid. Based on existing techniques that allow a surface to be calculated from three points not on a straight line, the control module calculates an equation for the plane position of the test liquid 23. It should be noted that the coordinate system is a relative coordinate system centered at (0, 0, 0); the absolute position will change with the position of the outer barrel 2.

[0040] The control module calculates the current liquid level inclination based on the position of the test liquid 23 and the reference plane. The control module is preset with a rated liquid level inclination value. When the current liquid level inclination calculated by the control module exceeds the rated liquid level inclination value, the control module issues a tilt alarm message, indicating that the barrel has abnormally tilted, i.e., the tilting process is not in the production process.

[0041] In this embodiment, the control module presets a safety height rating for each level transmitter 3. When the height information obtained by the control module regarding the test liquid 23 exceeds the safety height rating, the control module issues a height alarm. The safety height of the level transmitter 3 indicates that the conveyed liquid may or has reached a height at which it may overflow, prompting the operator to conduct an inspection.

[0042] Theoretically, only three liquid level transmitters 3 are needed for monitoring. However, if a level transmitter 3 malfunctions during transport, meaning the Z value at a specific location is incorrect, this can lead to an overall calculation error and an incorrect judgment. To prevent this, four level transmitters 3 are installed. Four data sets can be permuted and calculated up to four times. The control module calculates the position of the 3-4th plane based on the four data sets from the four level transmitters 3. When the error in the 3-4th plane is less than the error standard, the average of the 3-4th inclination is calculated as the final output value. This indicates that all level transmitters 3 are functioning normally. When the error in the 3-4th plane is greater than the error standard, the current liquid level inclination with the largest inclination is used as the final output value, and an abnormality alert is issued. This indicates that the Z value of one of the level transmitters 3 is incorrect. If the problem cannot be immediately identified, the largest inclination is used as the judgment criterion. Once the inspection conditions are met, repairs are immediately performed.

[0043] In this embodiment, the control module can be built into the outer barrel 2, and all data received and calculated are transmitted to the upper control device via wireless transmission. Of course, the control module is located in the upper control device, and after receiving the height position information of the test liquid 23 monitored by the liquid level transmitter 3 via wireless transmission, it performs the corresponding calculations.

[0044] The outer barrel 2 can also be tilted using other methods known in the art. Although this invention is specifically designed to address the abnormal tipping of liquid chemical materials, it is equally applicable to the abnormal tipping of containers carrying solid materials. The inner and outer barrels can be configured with mechanical structures such as lugs, a lid, and components to facilitate tipping, depending on the production equipment; the barrel structure is not limited to that shown in the embodiment.

[0045] The embodiments described above are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
