Description

Technical Field

[0001] This utility model relates to the field of flow meter technology, specifically to a bidirectional probe structure for a vortex flow meter. Background Technology

[0002] A bidirectional flowmeter probe is a device used to measure the flow rate of fluid in a pipe. This probe is specifically designed to detect and record the flow of fluid in two opposite directions, hence the name "bidirectional." It typically contains sensor elements that sense both the velocity and direction of the fluid.

[0003] However, in existing technologies, most bidirectional probes are directly exposed to the air without protective covers or shells. Impacts from external objects can cause surface wear, deformation, or breakage, leading to signal distortion, decreased measurement accuracy, or even complete failure. This necessitates frequent replacements or repairs, increasing maintenance costs. Therefore, we provide a bidirectional probe structure for vortex flow meters. Utility Model Content

[0004] The purpose of this invention is to provide a bidirectional probe structure for a vortex flowmeter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bidirectional probe structure for a vortex flowmeter, comprising a pipe, flanges at both ends of the pipe, a base at the top of the pipe, a protective cover at the top of the base, a transparent plastic plate in a slot on one side of the protective cover, two wiring slots on one side of the protective cover, mating blocks on both sides of the bottom of the protective cover, fixing blocks on the other two sides of the bottom of the protective cover, mating grooves on both sides of the top of the base, slots on the other two sides of the top of the base, springs in both slots, fixing slots on the side of the base near the two slots, and an auxiliary mechanism on the outside of the flanges.

[0006] As a further preferred embodiment of this technical solution, the auxiliary mechanism includes a protective sleeve that is fitted over the outside of the flange, and four reinforcing blocks are fixedly connected to the bottom of the base, with the other side of each of the four reinforcing blocks fixedly connected to the outside of the pipe.

[0007] As a further preferred embodiment of this technical solution, flanges are fixedly connected to both ends of the pipe, and a probe body is fixedly installed on the top of the pipe.

[0008] As a further preferred embodiment of this technical solution, the bottom of the base is fixedly connected to the top of the pipe, and a transparent plastic plate is fixedly connected in a slot opened on one side of the protective cover.

[0009] As a further preferred embodiment of this technical solution, the bottom two sides of the protective cover are fixedly connected with docking blocks, and the other two sides of the bottom of the protective cover are fixedly connected with fixing blocks.

[0010] As a further preferred embodiment of this technical solution, the mating block is inserted into the mating groove, and the fixing block is inserted into the slot.

[0011] As a further preferred embodiment of this technical solution, the protrusion of the fixing block is engaged in the fixing groove, and the end of the spring away from the fixing groove is fixedly connected to the side of the inner wall of the slot away from the slot.

[0012] This utility model provides a bidirectional probe structure for a vortex flow meter, which has the following advantages: (1) This utility model uses docking blocks and docking slots to place the protective cover on the base, which can then assist the fixing block in inserting into the slot. The spring will be briefly squeezed and deformed. When the fixing block is fully inserted into the slot, the spring will release its elasticity, and the protruding part of the fixing block will be engaged in the fixing slot. Therefore, the protective cover will be fixed and limited on the base and protect the probe body, avoiding external impacts that could cause wear, deformation or breakage of the probe surface, thus ensuring the service life of the probe.

[0013] (2) This utility model avoids damage such as wear and corrosion on the flange surface by putting the protective sleeve on the outside of the flange, thus greatly extending the service life of the flange. The connection strength between the base and the pipe can be increased by providing a reinforcing block between the pipe and the base. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1-5 As shown, in this embodiment, a bidirectional probe structure for a vortex flowmeter includes a pipe 11, with flanges 12 at both ends of the pipe 11, and the probe body 31 is fixedly installed on the top of the pipe 11. A base 13 is provided on the top of the pipe 11, and a protective cover 14 is provided on the top of the base 13. A transparent plastic plate 15 is installed in a slot on one side of the protective cover 14. The bottom of the base 13 is fixedly connected to the top of the pipe 11. The transparent plastic plate 15 is fixedly connected in a slot on one side of the protective cover 14. Two wiring slots 16 are provided on one side of the protective cover 14. Connecting blocks 17 are provided on both sides of the bottom of the protective cover 14. Fixed... The bottom sides of the fixed block 18 and the protective cover 14 are fixedly connected to the docking blocks 17. The bottom sides of the protective cover 14 are also fixedly connected to the fixing blocks 18. The top sides of the base 13 are provided with docking grooves 19. The top sides of the base 13 are provided with slots 110. The docking blocks 17 are inserted into the docking grooves 19. The fixing blocks 18 are inserted into the slots 110. The two slots 110 are provided with springs 111. The base 13 is provided with fixing grooves 112 on the side of the base 13 near the two slots 110. The protrusion of the fixing block 18 is engaged in the fixing groove 112. The end of the spring 111 away from the fixing groove 112 is fixedly connected to the side of the inner wall of the slot 110 away from the slot 110. The flange 12 is provided with an auxiliary mechanism 2.

[0022] In this embodiment, when protection of the probe body 31 is required, a protective cover 14 can be installed on the outside of the probe body 31. Specifically, the protective cover 14 is placed on the base 13 using the docking block 17 and the docking groove 19. This assists in inserting the fixing block 18 into the slot 110. The spring 111 will be briefly compressed, causing a contraction deformation. When the fixing block 18 is fully inserted into the slot 110, the spring 111 will release its elasticity, and the protruding part of the fixing block 18 will engage in the fixing groove 112, thus providing protection. The protective cover 14 is fixedly positioned on the base 13 and protects the probe body 31 from impacts from external objects, preventing wear, deformation, or breakage of the probe surface and ensuring the service life of the probe. When it is necessary to remove the protective cover 14, the protruding part of the fixing block 18 in the fixing groove 112 can be pressed. Therefore, the protruding part of the fixing block 18 will be recessed into the slot 110. After it is completely separated from the fixing groove 112, the protective cover can be pulled out to remove it from the base 13, avoiding the need to use traditional disassembly tools to disassemble and install the protective cover.

[0023] like Figures 1-5 As shown, the auxiliary mechanism 2 includes a protective sleeve 21, which is fitted onto the outside of the flange 12. Four reinforcing blocks 22 are fixedly connected to the bottom of the base 13, and the other side of each of the four reinforcing blocks 22 is fixedly connected to the outside of the pipe 11.

[0024] In this embodiment, when the equipment is idle, the protective sleeve 21 can be put on the outside of the flange 12 to avoid damage such as wear and corrosion on the surface of the flange 12, which greatly extends the service life of the flange 12. By providing a reinforcing block 22 between the pipe 11 and the base 13, the connection strength between the base 13 and the pipe 11 can be increased.

[0025] This utility model provides a bidirectional probe structure for a vortex flow meter, and its specific working principle is as follows: To effectively protect the probe body 31, a protective cover 14 can be installed externally. During installation, the protective cover 14 is precisely positioned on the base 13 by using the docking block 17 and the docking groove 19 on the base 13. Then, the auxiliary fixing block 18 is inserted into the corresponding slot 110. During this process, the spring 111 is compressed and contracts. When the fixing block 18 is fully inserted, the spring 111 returns to its original position, and its protruding part is just locked into the fixing groove 112. Thus, the protective cover 14 is firmly fixed on the base 13, providing reliable protection for the probe body 31 and preventing the probe surface from being worn, deformed, or broken due to collisions with external objects, thereby effectively extending the service life of the probe. When it is necessary to remove the protective cover 14, press down on the protruding part of the fixing block 18 in the fixing groove 112, causing the protruding part of the fixing block 18 to be recessed into the slot 110. After it is completely removed from the fixing groove 112, the protective cover 14 can be easily removed from the base 13 by simply pulling it out. There is no need to use traditional disassembly tools, making the operation convenient and efficient.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
