Description

Technical Field

[0001] This utility model relates to a monitoring device, specifically a railway fuel receiving and dispatching monitoring device, belonging to the field of fuel receiving and dispatching monitoring technology. Background Technology

[0002] In railway freight transport, fuel handling is a crucial link, affecting cargo safety and transportation efficiency. The application of railway fuel handling monitoring instruments can significantly improve the automation and monitoring accuracy of this process, reducing errors and waste from manual operation, making it an indispensable part of modern railway freight transport. Ultrasonic fuel level monitors use non-contact ultrasonic technology to measure the fuel level in containers such as storage tanks and tank cars in real time, and directly calculate the fuel quantity based on the container's geometric parameters.

[0003] However, in existing ultrasonic fuel level monitors, the sensor is usually attached to the surface of the fuel tank and is exposed. When the sensor is hit by an external object, even if it can still work, the measurement error may increase due to the fixed position or slight changes in the internal components, which may affect the accuracy of fuel level monitoring. Utility Model Content

[0004] The purpose of this utility model is to provide a railway fuel receiving and dispatching monitoring device to solve the above problems. When the monitoring instrument sensor is placed in the bottom plate, it can be resisted by rotating the limiting plate. Rotating the positioning block makes the locking rod located in the limiting plate and the support base, thus facilitating the protection of the monitoring instrument sensor while also allowing for quick assembly and disassembly.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a railway fuel receiving and dispatching monitoring device, comprising a base plate, on which a fixing mechanism, a limiting mechanism, and a patch are installed. A monitoring mechanism is engaged within the fixing mechanism. The limiting mechanism includes a mounting block and a limiting plate. The mounting block and a support base are fixedly connected to the base plate. The limiting plate is rotatably connected to the mounting block. A protrusion is fixedly installed on the limiting plate. A locking rod passes through the support base. The locking rod is engaged with the limiting plate, and both ends of the locking rod are threaded with positioning blocks.

[0006] Preferably, the two mounting blocks are symmetrically arranged on both sides of the limiting plate, and the mounting blocks are located at the end of the limiting plate closer to the protrusion.

[0007] Preferably, the end of the limiting plate opposite to the mounting block is engaged with the support base, and the locking rod penetrates the inner wall of the limiting plate.

[0008] Preferably, the positioning block is arranged in a regular hexagonal structure and the positioning block is in contact with the side wall of the support base.

[0009] Preferably, the two patches are arranged symmetrically, and the patches are located on the side of the base plate away from the support.

[0010] Preferably, the fixing mechanism includes a collar and a washer. The collar is fixedly connected to the base plate. The collar is provided with a wire feeding groove, a limiting groove and a locking groove. The washer is engaged with the locking groove.

[0011] Preferably, the washer and the collar are engaged, and the inner diameter of the washer is smaller than the inner diameter of the groove.

[0012] Preferably, a limiting plate is engaged with the limiting groove portion, and the limiting plate contacts the top end of the washer.

[0013] Preferably, the monitoring mechanism includes a sensor and a connecting line. The sensor is fitted inside the collar and the base plate, and the sensor is electrically connected to the GPS host via the connecting line.

[0014] Preferably, the washer ring is in contact with the sensor, and the connecting wire is located in the wire feeding groove.

[0015] The beneficial effects of this utility model are as follows: Before installing the monitoring sensor, the protrusion can be pressed to make one end of the limiting plate rotate along the mounting block. The mounting block is fixed on the base plate. After the limiting plate is rotated open, the monitoring sensor is placed in the base plate and the fixing mechanism. Then, the limiting plate is reset so that the end away from the mounting block can be engaged in the support seat fixed on the base plate. Since both the limiting plate and the support seat have through holes, the clamping rod is inserted through the inner wall of the limiting plate and the support seat and engaged in the through hole. Then, the positioning block is threaded onto both ends of the clamping rod using a tool, which can limit the limiting plate. This facilitates the protection of the monitoring sensor and also allows for quick assembly and disassembly. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-6 As shown, a railway fuel receiving and dispatching monitoring device includes a base plate 1. A fixing mechanism 2, a limiting mechanism 3, and a patch 5 are installed on the base plate 1. A monitoring mechanism 4 is engaged within the fixing mechanism 2. The limiting mechanism 3 includes a mounting block 301 and a limiting plate 303. The mounting block 301 and a support base 304 are fixedly connected to the base plate 1. The limiting plate 303 is rotatably connected to the mounting block 301. A protrusion 302 is fixedly installed on the limiting plate 303. A locking rod 305 passes through the support base 304. The locking rod 305 is engaged with the limiting plate 303, and both ends of the locking rod 305 are threaded with positioning blocks 306.

[0025] As a technical optimization of this utility model, the two mounting blocks 301 are symmetrically arranged on both sides of the limiting plate 303, and the mounting blocks 301 are located at the end of the limiting plate 303 near the protrusion 302. When the protrusion 302 is pressed, one end of the limiting plate 303 can rotate along the inner wall of the mounting block 301.

[0026] As a technical optimization of this utility model, the end of the limiting plate 303 facing away from the mounting block 301 is engaged with the support base 304, and the locking rod 305 penetrates the inner wall of the limiting plate 303. After the end of the limiting plate 303 facing away from the mounting block 301 rotates out from the support base 304, the collar 201 can be in an open state.

[0027] As a technical optimization of this utility model, the positioning block 306 is arranged in a regular hexagonal structure. The positioning block 306 contacts the side wall of the support base 304. The positioning block 306 limits the position of the locking rod 305, so that it is inside the limiting plate 303 and the support base 304.

[0028] As a technical optimization of this utility model, the two patches 5 are symmetrically arranged, and the patches 5 are located on the side of the base plate 1 away from the support seat 304. When the sensor 401 is installed in the base plate 1 and the collar 201, the sensor 401 can be installed on the oil tank through the patches 5.

[0029] As a technical optimization of this utility model, the fixing mechanism 2 includes a collar 201 and a washer 202. The collar 201 is fixedly connected to the base plate 1. The collar 201 is provided with a wire feeding groove 203, a limiting groove 204 and a locking groove 205. The locking groove 205 engages with the washer 202. The washer 202 can protect the sensor 401 and prevent it from wearing.

[0030] As a technical optimization of this utility model, the washer 202 and the collar 201 are engaged and connected. The inner diameter of the washer 202 is smaller than the inner diameter of the groove 205. The washer 202 abuts against the sensor 401 to prevent the sensor 401 from shifting within the collar 201.

[0031] As a technical optimization of this utility model, a limiting plate 303 is engaged and installed in the limiting groove 204. The limiting plate 303 contacts the top of the washer 202. When the limiting plate 303 is engaged in the limiting groove 204, it can squeeze the washer 202.

[0032] As a technical optimization of this utility model, the monitoring mechanism 4 includes a sensor 401 and a connecting line 402. The sensor 401 is installed in the collar 201 and the base plate 1. The sensor 401 is electrically connected to the GPS host 403 through the connecting line 402. The sensor 401 is in contact with the surface of the oil tank. It can measure the oil level in containers such as oil storage tanks and oil tank trucks in real time through non-contact ultrasonic technology, and directly calculate the oil volume by combining the container's geometric parameters.

[0033] As a technical optimization of this utility model, the washer ring 202 is in contact with the sensor 401, and the connecting line 402 is located at the wire release groove 203. The setting of the wire release groove 203 makes it convenient for the operator to position the connecting line 402 of the sensor 401.

[0034] In use, before installing the sensor 401, the protrusion 302 can be pressed to rotate one end of the limiting plate 303 along the mounting block 301. The mounting block 301 is fixed to the base plate 1. After the limiting plate 303 is rotated open, the sensor 401 is placed into the base plate 1 and the collar 201, which is fixed to the base plate 1. When the sensor 401 contacts the inner wall of the base plate 1, the washer 202 is placed into the slot 205 on the collar 201. The diameter of the washer 202 is larger than the diameter of the sensor 401. When it is inside the collar 201, it can abut against the top of the sensor 401. Then, the limiting plate 303 is reset so that the end facing away from the mounting block 301 can be locked onto the base plate 1. Inside the support base 304, the collar 201 has a limiting groove 204 to limit the limiting plate 303. Since both the limiting plate 303 and the support base 304 have through holes, the locking rod 305 is inserted through the inner walls of the limiting plate 303 and the support base 304, making it engage with the through hole. Then, the positioning block 306 is threaded onto both ends of the locking rod 305 using a tool, thereby limiting the limiting plate 303. This facilitates the protection of the sensor 401 while also allowing for quick assembly and disassembly. After fixing the sensor 401, the patch 5 fixed on the side of the base plate 1 away from the limiting plate 303 is attached to the surface of the oil tank, allowing the sensor 401 to contact the oil tank. The ultrasonic ceramic wafer layer in the sensor 401 emits primitive mechanical waves under the drive of an external excitation source. These mechanical waves propagate in the medium and are reflected and refracted when they encounter the interface between different media. Inside the fuel tank, mechanical waves pass through the inner wall and enter the liquid, where they are reflected at the liquid-air interface and then return along the same path. The returning mechanical waves resonate with the ceramic wafer, generating a sinusoidal voltage signal in the microvolt to millivolt range. This signal, after amplification and processing, allows for the calculation of the liquid level, thus enabling fuel quantity monitoring.
