Description

Technical Field

[0001] The utility model relates to the technical field of chemical liquid transportation detection, and particularly relates to a flow velocity induction structure for a dangerous chemical liquid transportation pipe. Background Art

[0002] When transporting chemical liquids through pipelines, too high a flow rate may increase the stress on the pipelines and connectors, leading to an increased risk of leakage or rupture. Therefore, by monitoring the flow rate, timely adjustments can be made to avoid such situations.

[0003] A Chinese patent with the publication number CN208621639U discloses a flow velocity induction structure for a chemical liquid transportation pipe, which includes an infusion pipe made of a non-metallic material. The infusion pipe is arranged in the left-right direction, and a spring arranged in the left-right direction is provided inside the infusion pipe. The left end of the spring is fixed to the infusion pipe, and a metal ball is fixedly connected to the right end of the spring. When the sensing element senses the metal ball, the sensing element emits a signal, enabling the staff to know that the liquid flow rate and pressure in the infusion pipe are too high, thereby playing a warning role and avoiding the occurrence of safety accidents.

[0004] Based on the above situation, the current inventor believes that to ensure the accuracy of flow velocity induction, multiple induction structures often need to be arranged along the pipeline. However, traditional induction structures are often installed individually in the pipeline one by one, which is rather inconvenient and time-consuming and laborious during installation and maintenance. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flow velocity induction structure for a dangerous chemical liquid transportation pipe, which has the effect of quickly distributing and installing the induction structure along the pipe body, reducing the time during installation and maintenance operations, and improving the operation efficiency.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A flow velocity induction structure for a dangerous chemical liquid transportation pipe includes a pipe body and an induction assembly;

[0007] Flanges are fixedly provided at both ends of the pipe body. The induction assembly includes a sticking plate and an induction frame. The outer side of the sticking plate is mutually attached to the flange. One end of the induction frame is fixed to the sticking plate, and the other end extends into the interior of the pipe body to sense the flow rate of the chemical liquid in the pipe body through the induction frame.

[0008] The further setting of the utility model is: The induction frame includes a frame body fixedly connected to the sticking plate at one end, an assembly component detachably installed on the frame body, a sensing plate fixedly provided on the assembly component, and a fixing component with the bottom end connected to the assembly component.

[0009] By adopting the above technical solution, it is convenient to send the three together into the pipe body for operation through the frame body.

[0010] A further setting of the present utility model is that the induction plate includes a plate body, a rotating rod fixedly installed at the bottom end of the plate body, and an induction cylinder connected to the rotating rod.

[0011] By adopting the above technical solution, the plate body is in contact with the chemical liquid, and the movement state of the plate body is judged through the induction cylinder.

[0012] A further setting of the present utility model is that the whole plate body is perpendicular to the chemical liquid conveying direction.

[0013] By adopting the above technical solution, when the chemical liquid flows in the pipe body, it can make contact impact with the plate body head-on.

[0014] A further setting of the present utility model is that the induction cylinder includes a cylinder body, a synchronous rod rotatably installed in the cylinder body, a detector with a detection end fixed to one end of the synchronous rod, and a first torsion spring installed on the synchronous rod. The other end of the synchronous rod is fixed to the rotating rod.

[0015] By adopting the above technical solution, when the plate body is tilted by the impact of the liquid, the synchronous rod can be driven to rotate by the rotating rod.

[0016] A further setting of the present utility model is that the type of the detector is a corner sensor.

[0017] By adopting the above technical solution, the tilting state of the plate body can be detected.

[0018] A further setting of the present utility model is that the assembly component includes an assembly groove and a mounting block.

[0019] By adopting the above technical solution, the induction plate is arranged on the mounting block to facilitate quick loading and unloading from the assembly groove.

[0020] A further setting of the present utility model is that the assembly groove includes a groove body and a limiting groove opened on the frame body.

[0021] A further setting of the present utility model is that the mounting block includes an insertion block and a limiting block respectively inserted into the groove body and the limiting groove.

[0022] By adopting the above technical solution, the cylinder body can be quickly loaded and unloaded on the frame body through the insertion block, improving the convenience of maintenance and replacement.

[0023] A further setting of the present utility model is that the fixing component includes a rotating buckle, a bottom column with a top end fixedly connected to the rotating buckle, a pressing rod with a bottom end slidably attached to the frame body and the insertion block, and a second torsion spring installed on the bottom column. The bottom end of the bottom column is rotatably connected to the frame body, and the top end of the pressing rod is fixedly connected to the rotating buckle.

[0024] By adopting the above technical solution, when it is necessary to take out the insertion block, only need to rotate the rotating buckle so that the pressing rod moves out of the upper surface of the insertion block.

[0025] The beneficial effects of the present utility model are as follows:

[0026] When the chemical liquid flows in the pipe body, it can directly contact the plate body, so that the plate body is tilted through the rotating rod after being impacted by the liquid, and the tilt state of the plate body is detected by the induction cylinder to obtain the real-time flow rate data of the liquid. When the induction plate is installed along the pipe body, it can be directly installed integrally through the frame body. When it needs to be taken out, the assembly component can also be used to quickly operate the induction plate that needs to be replaced and taken out, so as to improve the convenience of installation and replacement of the induction plate and shorten the operation time.

Detailed Embodiments

[0033] The technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only some of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.

[0034] An embodiment of the present utility model specifically provides a flow rate sensing structure for a dangerous chemical liquid conveying pipe. Please refer to Figure 1 , which includes a pipe body 1 and a sensing assembly 2.

[0035] Among them, flanges 21 are fixedly provided at both ends of the pipe body 1 to be hermetically connected to other pipes through the flanges 21. The sensing assembly 2 includes a bonding plate 3 and a sensing frame 4. The outer side of the bonding plate 3 is mutually attached to the flange 21. When the pipeline is installed, the flanges 21 between different pipe bodies 1 are tightly attached to both sides of the bonding plate 3. Holes matching the bolt holes of the flange 21 are provided on the bonding plate 3 to facilitate the bolts to pass through the holes and install and fasten the flange 21, so that the bonding plate 3 can be stably installed between the pipelines.

[0036] Specifically, one end of the sensing frame 4 is fixed to the bonding plate 3, and the other end extends into the pipe body 1 to sense the flow rate of the chemical liquid in the pipe body 1 through the sensing frame 4.

[0037] Further, please refer to Figure 2 , the sensing frame 4 includes a frame body 5 fixedly connected to one end of the bonding plate 3, an assembly component 6 detachably installed on the frame body 5, a sensing plate 7 fixedly provided on the assembly component 6, and a fixing component 8 connected to the bottom end of the assembly component 6. The assembly component 6, the sensing plate 7, and the fixing component 8 are all fixedly provided at two or more positions at intervals along the length direction of the frame body 5 to facilitate sending the three together into the pipe body 1 for operation through the frame body 5, and can also be taken out together when needed, without installing traditional detection equipment one by one in the pipe body 1 and also taking them out one by one when taking them out, optimizing the operation method and improving the operation convenience.

[0038] Among them, please refer to Figure 3 , the sensing plate 7 includes a plate body 71, a rotating rod 72 fixedly installed at the bottom end of the plate body 71, and a sensing cylinder 73 connected to the rotating rod 72. The plate body 71 is in contact with the chemical liquid, and the movement state of the plate body 71 is judged through the sensing cylinder 73, so as to obtain the flow rate of the chemical liquid.

[0039] During implementation, the whole plate body 71 is perpendicular to the chemical liquid conveying direction, so that when the chemical liquid flows in the pipe body 1, it can come into contact and impact with the plate body 71 frontally, and after the plate body 71 is stressed, it drives the rotating rod 72 to rotate, and the inclination angle of the plate body 71 is judged through the sensing cylinder 73, so as to obtain the flow rate data.

[0040] Further, please refer to Figure 4The sensing cylinder 73 includes a cylinder body 731, a synchronization rod 732 rotatably installed in the cylinder body 731, a detector 733 whose detection end is fixed to one end of the synchronization rod 732, and a first torsion spring 734 installed on the synchronization rod 732. The other end of the synchronization rod 732 is fixed to the rotating rod 72, so that when the plate body 71 is tilted by the impact of liquid, the synchronization rod 732 can be driven to rotate by the rotating rod 72.

[0041] Among them, the detector 733 is a rotation angle sensor, which is used to detect the tilt state of the plate body 71. The first torsion spring 734 is used to provide a rotational reset force for the synchronization rod 732. At the same time, the torsion of the first torsion spring 734 can also make the synchronization rod 732 subject to a certain rotational restriction force. Therefore, by controlling the torsion of the first torsion spring 734 and the rotation angle of the synchronization rod 732 detected by the detector 733, the tilt state of the plate body 71 is obtained, and the data is transmitted to the external controller through the detector 733 to receive the flow rate data. During implementation, the flow rate represented by the data of different tilt states of the plate body 71 needs to be actually measured multiple times according to the conditions of the flowing liquid. The relevant implementation steps are all existing methods, so they will not be described in detail here.

[0042] Furthermore, in order to facilitate the inspection and assembly and disassembly of the induction plate 7, the assembly component 6 includes an assembly groove and a mounting block, and the induction plate 7 is arranged on the mounting block to facilitate quick assembly and disassembly from the assembly groove.

[0043] The assembly groove includes a groove body 61 and a limiting groove 62 formed on the frame body 5 .

[0044] The mounting block includes an insert block 51 and a limit block 52 which are respectively plugged into the groove body 61 and the limit groove 62. The outer side of the cylinder 731 is fixed to the insert block 51, so that the cylinder 731 can be quickly loaded and unloaded on the frame 5 through the insert block 51, thereby improving the convenience of maintenance and replacement.

[0045] Among them, in order to ensure the stable installation of the plug block 51, the fixing component 8 includes a turn buckle 81, a bottom column 82 whose top is fixed to the turn buckle 81, a pressure rod 83 whose bottom end is slidingly fitted with the frame body 5 and the plug block 51, and a second torsion spring 84 installed on the bottom column 82. The second torsion spring 84 is used to provide a rotational reset force for the bottom column 82. The bottom end of the bottom column 82 is rotationally connected to the frame body 5, and the top of the pressure rod 83 is fixedly connected to the turn buckle 81. When the plug block 51 needs to be removed, it is only necessary to rotate the turn buckle 81 to move the pressure rod 83 out of the upper surface of the plug block 51. When the plug block 51 is installed, the pressure rod 83 is used to contact the surface of the plug block 51, so that the plug block 51 can be stably inserted into the slot body 61.

[0046] The control method of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common general knowledge in the art. Moreover, the present utility model is mainly used to protect mechanical devices. Therefore, the control method and circuit connection of the present utility model will not be explained in detail herein.

[0047] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
