Description

Technical Field

[0001] This utility model relates to the field of monitoring and alarm device technology, and in particular to a monitoring and alarm device for the oil outlet of an oil tank. Background Technology

[0002] As a critical component of the lubrication system, the oil distributor's outlet status directly determines the stability of oil supply to downstream lubrication points. Blockages, leaks, or abnormal oil flow at the outlet can lead to insufficient or excessive oil supply to lubrication points, resulting in increased friction, accelerated component wear, and even equipment shutdown or safety accidents. Therefore, installing a monitoring and alarm device at the oil distributor's outlet is essential for real-time monitoring of the oil flow status and timely fault warnings, ensuring reliable operation of the lubrication system and extending equipment lifespan.

[0003] Existing monitoring and alarm systems for oil distribution tank outlets are mostly installed in conjunction with traditional lubrication systems (such as dry oil dual-line systems). Typically, a flow sensor, pressure detector, and other monitoring components need to be deployed separately at each oil outlet, and the signals are transmitted to a remote control terminal via independent cables. Additionally, alarm indicator lights or audible alarms are required. The various monitoring and alarm components are dispersed on the outer wall of the oil distribution tank and along the pipeline, relying on traditional pipeline layout to achieve basic status monitoring.

[0004] However, the existing monitoring and alarm system has a relatively complex installation structure: the dispersed arrangement of monitoring elements and alarm components results in a large overall system space occupation, and the connection lines of each component are messy and easily affected by environmental factors such as dust and vibration on site, resulting in a low protection level. In order to solve this problem, we propose a monitoring and alarm device for the oil outlet of the oil tank. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a monitoring and alarm device for the oil outlet of an oil distribution tank.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A monitoring and alarm device for the oil outlet of an oil distribution tank includes an oil outlet of the oil distribution tank, a detection mechanism, a first connecting pipe, a flow control valve, a second connecting pipe, and a sixth flange. The first connecting mechanism is installed between the oil outlet of the oil distribution tank and the detection mechanism, and the second connecting mechanism is installed between the first connecting pipe and the detection mechanism. The detection mechanism is used to monitor the pressure and flow rate of the oil in real time. The flow control valve controls the flow rate of the oil. The sixth flange connects the second connecting pipe to the downstream lubrication system.

[0008] The detection mechanism includes a three-way pipe. One end of the three-way pipe is connected to the oil outlet of the oil distribution tank through a first connecting mechanism, and the other end of the three-way pipe is connected to a first connecting pipe through a second connecting mechanism. A third flange is fixed on the three-way pipe, and a mounting plate is installed on the third flange by locking bolts. A mounting base is fixed on the mounting plate, and a control host is installed on the top of the mounting base. The mounting base is inserted into the interior of the three-way pipe and connected to a pressure sensor and a flow detector.

[0009] Preferably, the first connecting mechanism includes a first flange fixed to the oil outlet of the oil distribution tank and a second flange fixed to one end of the tee pipe. A connecting sleeve is installed between the first flange and the second flange. Both ends of the connecting sleeve are fixed with threaded posts. The threaded posts on both sides pass through the first flange and the second flange respectively and are connected to nuts by threads.

[0010] Preferably, the number of threaded posts is several, and the several threaded posts are located on the side of the connecting sleeve and are distributed in a circumferential array.

[0011] Preferably, the second connecting mechanism includes a fourth flange fixed to the other end of the tee pipe and a fifth flange fixed to the first connecting pipe. The fourth flange and the fifth flange are fitted with fixing sleeves, and both ends of the fixing sleeves are provided with internal threads.

[0012] Preferably, the internal threads at both ends inside the fixing sleeve have opposite directions of rotation.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this utility model, the first connecting mechanism passes through the first and second flanges via threaded posts at both ends of the connecting sleeve, and achieves quick locking and disassembly with the help of nuts; the second connecting mechanism utilizes a fixing sleeve with internal threads of opposite directions at both ends, and can quickly connect or separate the fourth and fifth flanges by rotating it. This design greatly simplifies the disassembly and assembly process between the detection mechanism and the oil outlet of the oil distribution tank and the first connecting pipe, making it easier to maintain, repair or replace the detection mechanism and flow control valve in the future, and improving the convenience of equipment maintenance.

[0015] The testing agency uses pressure sensors and flow meters to monitor oil pressure and flow data in real time and transmits the information to the control unit. This allows for the timely detection of problems such as oil blockage, leakage, or abnormal flow, facilitating rapid fault warnings. Flow control valves precisely regulate oil flow, ensuring a stable oil supply to the downstream lubrication system and preventing accelerated equipment wear due to insufficient or excessive oil supply. Together, these two systems effectively guarantee the reliable operation of the lubrication system, helping to extend equipment lifespan and reduce losses caused by downtime due to malfunctions.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A monitoring and alarm device for the oil outlet of an oil distribution tank includes an oil outlet 1, a detection mechanism 3, a first connecting pipe 5, a flow control valve 6, a second connecting pipe 7, and a sixth flange 8. The first connecting mechanism 2 is installed between the oil outlet 1 and the detection mechanism 3, and the second connecting mechanism 4 is installed between the first connecting pipe 5 and the detection mechanism 3. The detection mechanism 3 is used to monitor the pressure and flow rate of the oil in real time, the flow control valve 6 controls the flow rate of the oil, and the sixth flange 8 connects the second connecting pipe 7 to the downstream lubrication system.

[0023] In this embodiment, refer to Figure 1 and Figure 2The detection mechanism 3 adopts an integrated design. Its core three-way pipe 31 serves as a channel for oil flow and is also locked to the mounting plate 33 by the third flange 32, which stably assembles the mounting base 35. This allows the pressure sensor 37 and flow meter 38 inserted inside the three-way pipe 31 to directly contact the oil. The control host 36 at the top centrally receives and processes the monitoring data. This structure avoids the problems of large space occupation and messy wiring caused by the dispersed arrangement of monitoring elements in the prior art. It also reduces the interference of environmental factors such as dust and vibration, improves the system protection level, and realizes real-time monitoring and fault early warning of oil pressure and flow, ensuring the accuracy and timeliness of monitoring.

[0024] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The first connecting mechanism 2 passes through the threaded posts 24 at both ends of the connecting sleeve 23 through the first flange 21 and the second flange 22, and is connected with the nut 25. Several threaded posts 24 are arranged in a circumferential array on the side of the connecting sleeve 23, which not only ensures the sealing and stability of the connection between the oil outlet 1 of the oil distribution tank and the three-way pipe 31, but also enables quick disassembly and assembly by loosening and tightening the nut. The second connecting mechanism 4 uses the internal threads 44 with opposite directions at both ends inside the fixed sleeve 43. After fitting the fourth flange 41 and the fifth flange 42, only the fixed sleeve needs to be rotated to lock or separate, which greatly simplifies the connection process between the three-way pipe 31 and the first connecting pipe 5. This quick-disassembly design effectively solves the problems of complex installation structure and inconvenient maintenance of the existing system, and significantly improves the convenience of later maintenance, repair or replacement of the detection mechanism 3 and the flow control valve 6.

[0025] When the first connecting mechanism 2 is installed, the threaded posts 24 at both ends of the connecting sleeve 23 pass through the first flange 21 and the second flange 22 respectively. The nuts 25 are tightened on the threaded posts 24 to fix the first flange 21, the second flange 22 and the connecting sleeve 23, so that the oil outlet 1 of the oil distribution tank is connected to the three-way pipe 31 of the detection mechanism 3 through the first connecting mechanism 2. When the second connecting mechanism 4 is installed, the fixing sleeve 43 is fitted on the outside of the fourth flange 41 and the fifth flange 42. Because the internal threads 44 at both ends of the fixing sleeve 43 turn in opposite directions, rotating the fixing sleeve 43 will lock the internal threads 44 at both ends with the fourth flange 41 and the fifth flange 42 respectively, so that the three-way pipe 31 is connected to the first connecting pipe 5 through the second connecting mechanism 4.

[0026] When the detection mechanism 3 is working, the three-way pipe 31 connects the oil outlet 1 of the oil distribution tank and the first connecting pipe 5. The mounting plate 33 on the third flange 32 is fixed by locking bolts. The mounting seat 35 on the mounting plate 33 is inserted into the three-way pipe 31. The pressure sensor 37 and the flow detector 38 are in contact with the oil to detect the pressure and flow of the oil in real time. The detection data is transmitted to the control host 36 on the top of the mounting seat 35. The flow control valve 6 is located between the first connecting pipe 5 and the second connecting pipe 7. According to the instructions of the control host 36, the flow of the oil is adjusted. The adjusted oil is transported to the sixth flange 8 through the second connecting pipe 7 and enters the downstream lubrication system through the sixth flange 8.

[0027] In summary, this utility model significantly simplifies the disassembly and assembly process of the detection mechanism, the oil outlet of the oil distribution tank, and the first connecting pipe through the quick-release design of the first and second connecting mechanisms, thereby improving maintenance convenience. In the detection mechanism, the pressure sensor and flow detector monitor the oil status in real time, and the data is transmitted to the control host to realize fault early warning. In conjunction with the flow control valve, the flow rate is precisely regulated to ensure stable oil supply to the downstream lubrication system, extend the service life of the equipment, and significantly improve the operational reliability of the lubrication system.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
