The liquid level measuring device includes: a mounting bracket 1; a measuring cylinder 4 having a measuring hole that axially penetrates the measuring cylinder 4 along its own axis. The measuring cylinder 4 is mounted on the mounting bracket 1 and is arranged above the liquid surface to be measured through the mounting bracket 1; a radar liquid level gauge 3, which is mounted above the measuring cylinder 4 through the mounting bracket 1 and is arranged at an interval from the measuring cylinder 4; and at least one purging member 5, which is mounted on the mounting bracket 1 for purging the space between the radar liquid level gauge 3 and the measuring cylinder 4.
[0024] With the above technical solution, in the liquid level measuring device provided by the present disclosure, the radar level gauge 3 is installed above the measuring cylinder 4 and arranged at an interval from the measuring cylinder 4, and the measuring cylinder 4 has a through measuring hole. In this way, the signal emitted by the radar level gauge 3 can pass through the measuring hole to ensure that the radar level gauge 3 can measure the liquid level of the liquid to be measured located below the measuring cylinder 4. In addition, the purging member 5 is used to purge the space between the radar level gauge 3 and the measuring cylinder 4 to blow away the fluid (such as hot steam with mud) between the radar level gauge 3 and the measuring cylinder 4. In this way, on the one hand, it can prevent impurities in the fluid from adhering to the probe of the radar level gauge 3, and on the other hand, it can prevent impurities in the fluid from adhering to the inner wall surface of the measuring cylinder 4 and causing the measuring hole to be blocked, so as to ensure the accuracy of the measurement result of the radar level gauge 3. In addition, the measuring cylinder 4 is installed above the liquid to be measured. Therefore, the measuring cylinder 4 can prevent the liquid to be measured from fluctuating due to the influence of the purging member 5, so as to further ensure the accuracy of the measurement result of the radar level gauge 3.
[0025] Among them, in an exemplary embodiment, referring to Figure 1 and Figure 2 as shown, the number of the purging members 5 can be two. Among them, each purging member 5 can be configured as a fan, and the two fans can be arranged at intervals. In other embodiments, the purging member 5 can also be configured in other suitable ways, and the present disclosure does not make specific limitations on this.
[0026] In the liquid level measuring device provided by the present disclosure, the mounting frame 1 can be configured in any suitable way. As an exemplary embodiment, referring to Figure 1 and Figure 2 as shown, the mounting frame 1 can include a first frame body, a second frame body and a plurality of connecting frame bodies. The first frame body and the second frame body can be arranged at intervals in the height direction, and the plurality of connecting frame bodies can be arranged at intervals along the length direction of the first frame body to connect the first frame body and the second frame body. The first frame body can be erected above the liquid to be measured, the measuring cylinder 4 can be installed on the first frame body, and the radar level gauge 3 can be detachably installed on the second frame body and arranged corresponding to the measuring cylinder 4. In this way, only by erecting the mounting frame 1 above the liquid to be measured, the liquid level of the liquid to be measured can be measured by using the radar level gauge 3, and the operation is convenient. Among them, the first frame body, the second frame body and the connecting frame body can be fixedly connected by welding or other means to ensure the stability of the mounting frame 1. Or, the first frame body, the second frame body and the connecting frame body can also be detachably connected by clamping or other means to facilitate disassembly, assembly and storage, and the present disclosure does not make specific limitations on this.
[0027] In the liquid level measuring device provided by the present disclosure, the second frame body can be configured in any suitable way. As an exemplary embodiment, referring to Figure 1 and Figure 2As shown, the second frame body may include a frame main body and a plurality of connecting rods 2. The plurality of connecting rods 2 may be cross-connected to the frame main body. The radar level gauge 3 may be fixedly installed on at least two connecting rods 2 through fasteners. The purging member 5 may be installed at the bottom of one of the connecting rods 2. In this way, by providing the plurality of cross-connected connecting rods 2, on the one hand, the purpose of improving the stability of the second frame body can be achieved, and on the other hand, it is convenient to install the radar level gauge 3 and the purging member 5. In addition, the detachable installation of the radar level gauge 3 and the connecting rod 2 is realized through fasteners, and the radar level gauge 3 can be installed after the installation frame 1 is installed. In this way, damage to the radar level gauge 3 during the manufacturing and installation of the installation frame 1 can be avoided. Among them, the fasteners may be configured as bolts and nuts. In other embodiments, the fasteners may also be configured in other suitable ways, and the present disclosure does not make specific limitations thereto.
[0028] In the liquid level measuring device provided by the present disclosure, as an exemplary embodiment, refer to Figure 1 and Figure 2 As shown, the liquid level measuring device may further include a diversion structure 6. The diversion structure 6 may be installed on the installation frame 1 and arranged opposite to the purging member 5 for diverting the fluid flowing through the space between the radar level gauge 3 and the measuring cylinder 4. In this way, the purging member 5 can blow the fluid (such as hot steam with mud) between the radar level gauge 3 and the measuring cylinder 4 towards the diversion structure 6, and flow out of the liquid level measuring device through the diversion structure 6.
[0029] Among them, the diversion structure 6 may be installed in any suitable manner. As an exemplary embodiment, refer to Figure 1 and Figure 2 As shown, both the first frame body and the second frame body may include a U-shaped frame main body. The U-shaped frame main body may include a connecting section and extension sections connected to both ends of the connecting section. The bottom and top of the side of the diversion structure 6 facing away from the purging member 5 may be fixedly connected to the connecting section of the first frame body and the connecting section of the second frame body respectively. In this way, the top and bottom of the diversion structure 6 can be fixedly connected to the first frame body and the second frame body respectively to improve the stability of the installation frame 1 and the diversion structure 6. In addition, the diversion structure 6 can be arranged between the first frame body and the second frame body in the height direction. That is to say, the fluid (such as hot steam with mud) flowing through the space between the radar level gauge 3 and the measuring cylinder 4 can all flow out of the liquid level measuring device through the diversion structure 6 to ensure the diversion effect of the diversion structure 6.
[0030] In the liquid level measuring device provided by the present disclosure, the diversion structure 6 may be configured in any suitable manner. As an exemplary embodiment, refer to Figure 1 and Figure 2As shown in the figure, the diversion structure 6 may include diversion plates and at least one reinforcing rod. The number of diversion plates may be multiple, and the multiple diversion plates may be arranged at intervals along the length direction of the connection section. The diversion plates may be configured in a wavy shape along the fluid flow direction, and the reinforcing rod may sequentially penetrate through the multiple diversion plates and be fixedly connected to the diversion plates. In this way, when impurities in the above-mentioned fluid (such as hot steam with mud) flow through the diversion structure 6, they will encounter the diversion plates and adhere to the diversion plates. That is to say, the diversion plates can collect the above-mentioned impurities (such as mud). Among them, the wavy design of the diversion plates can increase the fluid flow resistance and improve the collection ability of the diversion plates for the above-mentioned impurities (such as mud). In addition, by connecting the multiple diversion plates through the reinforcing rod, the displacement of the diversion plates during use can be prevented, so as to improve the stability of the diversion structure 6.
[0031] In the liquid level measuring device provided by the present disclosure, in order to facilitate the cleaning of the diversion structure 6, as an exemplary embodiment, refer to Figure 1 and Figure 2 As shown in the figure, the liquid level measuring device may further include a flushing structure, and the flushing structure may be arranged on the top of the diversion structure 6 for flushing the diversion plates. In this way, the liquid in the flushing structure can flush the diversion plates under the action of its own gravity to wash off the impurities (such as mud) on the surface of the diversion plates, avoiding the reduction of the collection ability of the diversion plates for the impurities (such as mud) due to excessive impurities (such as mud), and at the same time ensuring the diversion effect of the diversion structure on the fluid.
[0032] In the liquid level measuring device provided by the present disclosure, the flushing structure can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 1 and Figure 2 As shown in the figure, the flushing structure may include a water inlet pipe 8, a shunt pipe 7, and multiple flushing pipes 9. The water inlet pipe 8 and the multiple flushing pipes 9 may be communicated with the shunt pipe 7, and the multiple flushing pipes 9 may be arranged at intervals along the length direction of the shunt pipe 7. Compared with only setting one flushing pipe 9, the design of the above-mentioned multiple flushing pipes 9 can improve the flushing ability of the flushing structure.
[0033] In the liquid level measuring device provided by the present disclosure, in order to improve the flushing efficiency, as an exemplary embodiment, refer to Figure 1 and Figure 2 As shown in the figure, the number of the flushing pipes 9 and the diversion plates may be equal and arranged in one-to-one correspondence, and each flushing pipe 9 may be arranged on the top of the corresponding diversion plate. In this way, multiple flushing pipes 9 can be used to flush multiple diversion plates simultaneously to ensure that the collection ability of each diversion plate for impurities (such as mud) is comparable.
[0034] In the liquid level measuring device provided by the present disclosure, the measuring cylinder 4 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 1 and Figure 2As shown in [figure], the measuring cylinder 4 may include a base and a cylinder body. The base may be fixedly installed on the first frame body, and the cylinder body may extend from the base away from the liquid level to be measured. Among them, the base may be configured in a plate shape, and the two opposite ends of the base may be respectively connected to two extension segments of the first frame body. In this way, the stability of the measuring cylinder 4 and the first frame body can be improved. In addition, since the cylinder body extends from the base away from the liquid level to be measured, it can further prevent the blowing member 5 from blowing the liquid level to be measured and causing fluctuations in the liquid level to be measured.
[0035] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0036] In addition, it should be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.
[0037] In addition, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
