Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of monitoring devices, and particularly relates to a liquid level monitoring device for a mud buffer tank. Background Art
[0002] With the development of engineering construction technology, mud plays an important role in the drilling operation. The mud used for drilling can wash the cuttings carried at the bottom of the well. The mud also has the function of balancing the lateral pressure of the rock on the wellbore, forming a mud cake on the wellbore to maintain the stability of the wellbore and prevent the wellbore from collapsing. In the production of mud, the prepared mud will be temporarily stored in the mud buffer tank. There may be multiple buffer tanks on the same production line. During the production process, it is necessary to monitor the liquid level of the buffer tank for filling and use. Therefore, it is necessary to monitor the liquid level of each buffer tank, so as to facilitate the use adjustment according to the liquid level height of different buffer tanks. However, most of the existing detection devices are float type, and the float is used to judge whether the liquid level reaches the set height. However, the float monitoring device can only monitor whether the liquid level reaches a certain height during use, and the liquid level below and above this height cannot be intuitively displayed. Therefore, this technical solution is specifically proposed for improvement. Summary of the Utility Model

[0015] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.
[0016] See Figures 1 to 3, an embodiment of the utility model discloses a liquid level monitoring device for a mud buffer tank, which mainly consists of a support frame, a measuring component and a connecting component. Generally, the buffer tank body is an open cement tank. The support frame is used to be stably installed on the mud buffer tank body to ensure that the measuring component can work accurately and stably. The support frame includes a connecting buckle 201, a connecting rod 2 and an adjusting device. The connecting buckle 201 is designed as a C-shaped buckle with an open cross-section on one side, which is convenient for quick installation and disassembly. A locking bolt 202 is provided at the opening of the C-shaped buckle. By tightening the locking bolt 202, the measuring tube 1 can be firmly fixed inside the connecting buckle 201, and the up and down position of the measuring tube 1 can be adjusted to be applicable to buffer tank bodies of different depths.
[0017] The connecting rod 2 is vertically arranged on the side of the connecting buckle 201 and is used to connect the support frame with the buffer tank body, so that the measuring tube 1 can stand vertically inside the buffer tank body and contact the internal mud as much as possible. The length and strength of the connecting rod 2 are designed according to the size and weight of the buffer tank to ensure stable support. The adjusting device is used to be fixed on the side of the buffer tank body and is installed at the far end of the connecting rod 2 to be applicable to buffer tank bodies of different sizes and shapes. The adjusting device includes a fixed plate 203, a limiting hole, a guide plate 205, a moving plate 204 and an adjusting bolt 206. The fixed plate 203 is fixed on the connecting rod 2. The guide plate 205 is slidably arranged in the limiting hole. The other end of the guide plate 205 is connected to the moving plate 204. The moving plate 204 is parallel to the fixed plate 203, and the guide plate 205 is perpendicular to the moving plate 204. For buffer tank bodies with different installation positions and different thicknesses, by rotating the adjusting bolt 206, the distance between the moving plate 204 and the fixed plate 203 can be adjusted, so that it is fixed on the side of the buffer tank body and the measuring tube 1 is extended into the interior, and the adjusting structure is stable and has wide applicability.
[0018] The measuring component is used to monitor the height of the mud liquid level in real time. The measuring component includes a measuring tube 1. A connector 3 is screwed onto the top of the measuring tube 1. A pressure sensor 301 is arranged at the middle position on the top of the connector 3. The measuring tube 1 is cylindrical and is designed to have a sufficient length to penetrate into the mud buffer tank to ensure that it can accurately reflect the change of the liquid level. Scale lines 101 are arranged on the outer wall of the measuring tube 1. When the liquid level rises, the approximate position of the liquid level is indirectly indicated through the change of air pressure. The design of the scale lines 101 facilitates the operator to quickly read the data and can calibrate the pressure sensor 301. The connector 3 is arranged on the top of the measuring tube 1 and is used to connect the pressure sensor 301 and the measuring tube 1. The connector 3 and the measuring tube 1 are connected by a screwing method, and a rubber pad is arranged inside to ensure the sealing performance. The pressure sensor 301 is installed at the middle position of the connector 3 and is used to detect the change of air pressure inside the measuring tube 1. The bottom of the measuring tube 1 penetrates into the mud. When the mud liquid level rises, the air inside the measuring tube 1 will be compressed, resulting in an increase in air pressure; on the contrary, when the liquid level drops, the air pressure decreases. By monitoring the change of air pressure, the height of the liquid level can be indirectly known.
[0019] Working principle: When the device works, first install the support frame on the mud buffer tank body through the adjusting device to ensure that the measuring tube 1 is vertically and stably inserted into the mud. Then, start the pressure sensor 301 to start monitoring the change of air pressure inside the measuring tube 1 in real time. As the mud liquid level rises or drops, the air pressure inside the measuring tube 1 will change accordingly. The pressure sensor 301 converts this change into an electrical signal and outputs it. By processing this electrical signal, the height of the mud liquid level can be calculated and displayed or alarmed in the control system. The liquid levels of each buffer tank body can be remotely monitored, which is convenient for centralized control and improves the control effect.
