[0023] Example:

[0024] As Figures 1 to 5 shown, the utility model provides an improved pointer type floating ball liquid level meter, including flange plate 1, indicating dial 2 and multiple groups hollow structure and head-to-tail connecting connecting rod 3, the central part of flange plate 1 is provided with connecting piece 101, and the bottom of indicating dial 2 is detachably arranged in connecting piece 101;One group of connecting rod 3's top is connected with the bottom of connecting piece 101;The bottom of the connecting rod 3 away from flange plate 1 is also provided with end cover 102, and the floating ball 4 is movably arranged between the end cover 102 and multiple connecting rod 3, and the transmission rod 103 is also arranged at the top end of the floating ball 4, and the transmission rod 103 is connected with the indicating dial 2 through multiple connecting rod 3;The flange plate 1 close to connecting piece 101 is also provided with controller 5, and the end close to end cover 102 of floating ball 4 is also provided with sensor 104, and the sensor 104 is electrically connected with controller 5. Flange plate 1 central part is provided with connecting piece 101, and the bottom of indicating dial 2 is detachably arranged in connecting piece 101. This makes indicating dial 2 can be accurately positioned when installing, and in the subsequent use process, if indicating dial 2 appears fault or needs to be calibrated, replaced and other maintenance operations, it can be quickly disassembled, without large-scale disassembly of the whole liquid level meter, greatly improves the maintenance efficiency, reduces the maintenance difficulty and cost.

[0025] The plurality of groups of connecting rods 3 are hollow structures and are connected in a head-to-tail manner. Through the connecting rod 3 structure connected in a head-to-tail manner, the number of connecting rods 3 can be flexibly increased or reduced according to actual measurement requirements, and the overall length of the liquid level meter can be adjusted, so as to adapt to the liquid level measurement of containers of different heights and depths, and expand the application range of the liquid level meter. The floating ball 4 is movably arranged between the end cover 102 and the plurality of groups of connecting rods 3, and the transmission rod 103 at the top end thereof passes through the plurality of groups of connecting rods 3 and is connected with the indicating dial 2. The end cover 102 and the hollow connecting rod 3 lock the floating direction of the floating ball 4. When the liquid level changes, the floating ball 4 rises or falls with the liquid level, drives the transmission rod 103 to move in the hollow structure of the connecting rod 3, and then accurately transmits the vertical displacement of the floating ball 4 to the indicating dial 2, so that the pointer in the indicating dial 2 rotates, and the liquid level is intuitively and accurately displayed.

[0026] The controller 5 is arranged on the flange plate 1 close to the connecting piece 101, and the UQK-01 type can be selected. The sensor 104 is arranged on one end of the floating ball 4 close to the end cover 102 and is electrically connected with the controller 5. The sensor 104 can realize real-time sensing of the position change of the floating ball 4 and convert it into an electric signal to transmit to the controller 5. The controller 5 can process and convert the signal, and lay a foundation for subsequent realization of remote transmission and intelligent control of liquid level information, so that the operator can obtain the liquid level data through the remote equipment without being on site, and meet the needs of remote monitoring and automatic control of modern industrial production.

[0027] As Figure 1 , Figure 2 With Figure 4As shown, the end cover 102 is uniformly provided with a plurality of clamping pieces 201, and the bottom of one of the plurality of connecting rods 3 connected to the end cover 102 is provided with a plurality of clamping grooves 202 corresponding to the plurality of clamping pieces 201. The plurality of clamping pieces 201 are respectively detachably clamped in the plurality of clamping grooves 202. The plurality of connecting rods 3 and the end cover 102 are made of stainless steel. The peripheral side of the end cover 102 is also uniformly provided with a plurality of liquid permeable holes 301. The clamping piece 201 on the end cover 102 cooperates with the clamping groove 202 at the bottom of the connecting rod 3 to form a detachable connecting structure. When disassembled, the clamping piece 201 and the clamping groove 202 are directly separated. When assembled, the clamping piece 201 is inserted into the clamping groove 202, which facilitates quick replacement of damaged suspension balls 4 or connecting rods 3, eliminates the need to replace the entire liquid level gauge assembly, and reduces maintenance costs and time. The end cover 102 is provided with liquid permeable holes 301 on the peripheral side, and the liquid can flow freely through the liquid permeable holes 301. When the liquid level rises, the liquid acts on the bottom of the suspension ball 4 through the liquid permeable holes 301, and the suspension ball 4 rises. When the liquid level drops, the liquid flows out through the liquid permeable holes 301, and the suspension ball 4 drops, ensuring that the suspension ball 4 moves in time with the change in the liquid level and ensuring the accuracy of the liquid level measurement. The connecting rod 3 and the end cover 102 are made of stainless steel and are not rusted in a humid environment. They are not eroded by contact with corrosive liquids. Long-term use will not cause structural looseness due to material damage, ensuring the overall strength of the liquid level gauge, maintaining measurement stability, and avoiding measurement errors caused by component damage.

[0028] As shown in the drawings, Figure 2 As shown in the drawings, Figure 5 As shown, the bottom of the suspension ball 4 is also detachably provided with a bottom cover 401. The bottom cover 401 is provided with an assembly groove, and the sensor 104 is arranged in the assembly groove. A barrier cover 402 is arranged in the assembly groove on the peripheral side of the sensor 104. The suspension ball 4 is made of polypropylene, and the suspension ball 4 is filled with lightweight foamed plastic. The bottom of the suspension ball 4 is provided with a detachable bottom cover 401, which facilitates the installation and disassembly of the sensor 104. When the sensor 104 fails, it can be repaired and replaced by directly disassembling the bottom cover 401, without the need to disassemble the entire suspension ball 4, thereby reducing the difficulty and time cost of maintenance. The bottom cover 401 is provided with an assembly groove to fix the sensor 104, ensuring the stability of the position of the sensor 104 in the suspension ball 4. During the movement of the suspension ball 4 with the liquid level, the sensor 104 will not be displaced, ensuring the accuracy of the liquid level signal acquisition. At the same time, the barrier cover 402 is arranged in the assembly groove to isolate the sensor 104 from the external liquid. This prevents the liquid from directly contacting the sensor 104, avoids liquid corrosion and impact damage to the sensor 104, prolongs the service life of the sensor 104, and ensures the normal operation of the liquid level measurement system. The sensor 104 can be selected as a KFG-LEVEL type.

[0029] The suspension ball 4 is made of polypropylene material, which can resist corrosion of various corrosive liquids. In the corrosive environment of acid and alkali, the suspension ball 4 will not be corroded and damaged by the liquid, and the structure of the suspension ball 4 is maintained intact, so that the liquid level measurement is stable for a long time. The suspension ball 4 is filled with light foamed plastic, which can reduce the overall weight of the suspension ball 4, improve the suspension performance, and make the suspension ball 4 more sensitive to the change of the liquid level, so as to timely transmit the liquid level change signal and improve the sensitivity and accuracy of the liquid level measurement.

[0030] As shown in Figure 1 With Figure 3 As shown, the connecting piece 101 is also provided with a mounting groove, and a warning light 601 is arranged in the mounting groove and electrically connected with the controller 5. The connecting piece 101 is provided with the mounting groove for fixing the warning light 601, so that the warning light 601 is stably arranged on the liquid level meter and will not shake or shift during the working process, thereby ensuring that the warning function can normally work. The warning light 601 is electrically connected with the controller 5, and the controller 5 receives and processes the liquid level signal of the sensor 104. When the liquid level reaches the preset upper limit or lower limit value, the controller 5 sends an electric signal to the warning light 601, and the warning light 601 emits light to remind the on-site personnel. The on-site personnel do not need to check the remote data or read the reading of the indicating dial 2, but can quickly judge whether the liquid level is abnormal through the state of the warning light 601. In the sufficient light or complex environment, the warning light 601 can attract attention through the intuitive visual signal, and timely measures can be taken to avoid danger.

[0031] As shown in Figure 3 As shown, the bottom of the flange plate 1 is also provided with an assembly groove, and a sealing ring 701 made of rubber material is arranged in the assembly groove and can be replaced; the assembly groove is arranged at the bottom of the flange plate 1 to provide a mounting space for the sealing ring 701, so that the position of the sealing ring 701 is limited and the sealing ring 701 will not move randomly after being installed, thereby ensuring the stability of the sealing structure. The sealing ring 701 is made of rubber material and is elastic and deformable. When the flange plate 1 is connected with the container, the sealing ring 701 is pressed and filled in the connection gap, so that the liquid or gas is prevented from leaking from the connection, thereby ensuring the sealing property of the liquid level meter. Meanwhile, the sealing ring 701 can be replaced. When the sealing ring 701 is worn or aged and loses the sealing effect, the old sealing ring 701 can be directly taken out from the assembly groove, and the new sealing ring 701 can be installed, so that the sealing performance of the liquid level meter is restored, the service life of the liquid level meter is prolonged, and the maintenance cost is reduced.

[0032] The above merely describes the embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
