[0001] The utility model relates to the field of liquid level monitors, and particularly relates to a liquid level monitor for a liquid storage tank. Background Technique

[0002] A storage tank is an industrial tool used to store liquids. The material of the storage tank is basically metal, and its surface is not transparent, so the liquid level inside it cannot be observed with the naked eye. At this time, a liquid level monitor is needed, which can monitor the liquid level inside the storage tank in real time and send the liquid level information to the receiving device.

[0003] However, the liquid level monitors in the existing market are not easy to install during use. When the storage tank is large in volume, a large liquid level monitor needs to be installed. When directly installing with screws, the liquid level monitor needs to be aligned with the installation position and continuously held by hand, which is not convenient for the preliminary fixing of the liquid level monitor and reduces the installation efficiency.

[0004] Therefore, it is necessary to provide a liquid level monitor for a liquid storage tank to solve the above technical problems. Content of the Utility Model

[0005] The utility model provides a liquid level monitor for a liquid storage tank, which solves the problem that the liquid level monitors in the existing market are not easy to install during use. When the storage tank is large in volume, a large liquid level monitor needs to be installed. When directly installing with screws, the liquid level monitor needs to be aligned with the installation position and continuously held by hand, which is not convenient for the preliminary fixing of the liquid level monitor and reduces the installation efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described below with reference to the drawings and embodiments.

[0019] Please refer toFigure 1 , Figure 2 and Figure 3 , where Figure 1 is a schematic structural diagram of a preferred embodiment of a liquid level monitor for a liquid storage tank provided by the present utility model; Figure 2 is Figure 1 the schematic diagram of the jacket installation structure shown; Figure 3 is Figure 1 the schematic diagram of the second connecting pipe installation structure shown. A liquid level monitor for a liquid storage tank includes: a storage tank 1. On one side of the outside of the storage tank 1, a fixing plate 2 is fixedly installed, and the number of the fixing plates 2 is two. On the separated sides of the two fixing plates 2, mounting plates 3 are fixedly installed. On the outside of the two mounting plates 3, mounting grooves 4 are opened. Inside the two mounting grooves 4, a positive and negative screw rod 5 is rotatably installed through a bearing. One end of each of the two positive and negative screw rods 5 penetrates through the mounting plate 3 and extends to the outside. One end of each of the two positive and negative screw rods 5 is keyway-connected with a knob 6. The outside of the two positive and negative screw rods 5 is meshed with a jacket 7, and the number of the jackets 7 is four. The jacket 7 is slidably installed on the mounting plate 3 along the length direction of the positive and negative screw rod 5 through the mounting groove 4. When installing the liquid level gauge, first rotate the knob 6. The knob 6 drives the positive and negative screw rod 5 to rotate. The positive and negative screw rod 5 rotates to drive the two jackets 7 to move, so that the two jackets 7 move to both ends. Then, fit the second flange 12 with the first flange 11, and at the same time ensure that the second mounting holes 14 are aligned. Then rotate the knob 6 in the opposite direction. The knob 6 drives the positive and negative screw rod 5 to reverse, so that the two jackets 7 approach each other, thereby effectively performing a preliminary clamping and fixing process on the first flange 11 and the second flange 12. The structure is simple, and the installation difficulty of the liquid level gauge is greatly improved.

[0020] On one side of the outside of the storage tank 1 and between every two jackets 7, a first connecting pipe 10 is fixedly installed, and the number of the first connecting pipes 10 is two. One end of each of the two first connecting pipes 10 is fixedly installed with a first flange 11. On the outside of the two first flanges 11, a second flange 12 is fitted. On the outside of the two second flanges 12, a second connecting pipe 13 is fixedly installed. On the outside of the first flange 11 and the second flange 12, second mounting holes 14 are opened, and the number of the second mounting holes 14 is four. On the outside of the four jackets 7, first mounting holes 8 are opened, and the number of the first mounting holes 8 is multiple. On the outside of the four jackets 7, bolts 9 are threadedly connected through the first mounting holes 8. The bolts 9 penetrate through the first flange 11 and the second flange 12 through the second mounting holes 14. After the first flange 11 and the second flange 12 are preliminarily positioned, use the bolts 9 to penetrate through the first flange 11 and the second flange 12 respectively through the second mounting holes 14, and then threadedly install them with the jackets 7 through the first mounting holes 8, thereby effectively fixing the first connecting pipe 10 and the second connecting pipe 13. The structure is simple, and one person can install it without manually supporting the liquid level gauge, reducing the installation difficulty.

[0021] A liquid level tube 15 is fixedly installed between one ends of two second connecting tubes 13. The two first connecting tubes 10 are communicated with the storage tank 1. Therefore, the air pressure inside the storage tank 1 can be ensured to be the same as the air pressure inside the liquid level tube 15. At this time, the liquid height inside the liquid level tube 15 is equal to the liquid height inside the storage tank 1. And a liquid level sensor is arranged inside the liquid level tube 15. Through the sensor, the liquid level height signal can be sent to the receiving device, which is convenient for detecting the liquid level.

[0022] The working principle of a liquid level monitor for a liquid storage tank provided by the utility model is as follows:

[0023] The first step: When installing the liquid level monitor, first rotate the knob 6. The knob 6 drives the positive and negative screw rod 5 to rotate. The rotation of the positive and negative screw rod 5 drives the two clamping sleeves 7 to move, so that the two clamping sleeves 7 move to both ends. Then, the second flange 12 is fitted with the first flange 11, and at the same time, ensure that the second mounting holes 14 are aligned. Then rotate the knob 6 in the reverse direction. The knob 6 drives the positive and negative screw rod 5 to reverse, so that the two clamping sleeves 7 approach each other, thereby effectively performing a preliminary clamping and fixing treatment on the first flange 11 and the second flange 12. The structure is simple. One person can install it without manually supporting the liquid level monitor, reducing the installation difficulty.

[0024] The second step: The two first connecting tubes 10 are communicated with the storage tank 1. Therefore, the air pressure inside the storage tank 1 can be ensured to be the same as the air pressure inside the liquid level tube 15. At this time, the liquid height inside the liquid level tube 15 is equal to the liquid height inside the storage tank 1. And a liquid level sensor is arranged inside the liquid level tube 15. Through the sensor, the liquid level height signal can be sent to the receiving device, which is convenient for detecting the liquid level.

[0025] Compared with the related technology, a liquid level monitor for a liquid storage tank provided by the utility model has the following beneficial effects:

[0026] When installing the liquid level monitor, first rotate the knob 6. The knob 6 drives the positive and negative screw rod 5 to rotate. The rotation of the positive and negative screw rod 5 drives the two clamping sleeves 7 to move, so that the two clamping sleeves 7 move to both ends. Then, the second flange 12 is fitted with the first flange 11, and at the same time, ensure that the second mounting holes 14 are aligned. Then rotate the knob 6 in the reverse direction. The knob 6 drives the positive and negative screw rod 5 to reverse, so that the two clamping sleeves 7 approach each other, thereby effectively performing a preliminary clamping and fixing treatment on the first flange 11 and the second flange 12. The structure is simple, greatly increasing the installation difficulty of the liquid level monitor.
