Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic water meters, and particularly to an anti-electromagnetic interference protection mechanism for acoustic wave pipeline detection of ultrasonic water meters. Background Art

[0002] During the use of ultrasonic water meters, they are vulnerable to electromagnetic interference. Electromagnetic interference is caused by the generation of electromagnetic harmonics during the operation of the equipment itself or by the generation of electromagnetic harmonics by the surrounding equipment during operation. The existence of these electromagnetic harmonics may cause the equipment to malfunction. In severe cases of electromagnetic harmonics, it may lead to the damage of the equipment. However, the outer wall of the current ultrasonic water meters has no protection mechanism and is extremely vulnerable to the influence of electromagnetic interference, affecting the service life.

[0003] An anti-electromagnetic interference protection mechanism for acoustic wave pipeline detection of ultrasonic water meters with a publication number of CN112129368A includes an ultrasonic water meter body and a protection mechanism on the outer wall of the ultrasonic water meter body. The protection mechanism at least includes: protection shells. There are two symmetrically arranged protection shells, which are fixedly connected by bolts. The protection shells are in the shape of an inverted "T" - shaped metal shell. Both ends of the protection shells are provided with fitting plates. Rubber rings are arranged on the inner walls of the fitting plates, and rubber blocks are arranged at both ends of the fitting plates. The outer wall of the protection shell near the top is provided with external connection threads. In the specific use of the protection shell in this embodiment, the two protection shells are put together to cover the periphery of the ultrasonic water meter body. The rubber blocks are located between the two protection shells, which can ensure a tighter connection between the two protection shells. The present invention can protect the outer wall of the ultrasonic water meter, effectively shield the influence of electromagnetic interference, and is convenient for disassembly and installation.

[0004] The above technical solution can facilitate quick installation and connection, effectively improving the assembly efficiency. However, in its technical solution, the relative position relationship with the ultrasonic water meter cannot be effectively limited, which is not conducive to adapting to various specifications of ultrasonic water meters. Therefore, improvement is needed. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies in the prior art and propose an anti - electromagnetic interference protection mechanism for acoustic wave pipeline detection of ultrasonic water meters.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A sonic wave pipeline detection anti-electromagnetic ultrasonic water meter interference protection mechanism comprises an ultrasonic water meter assembly, wherein the front and rear ends of the ultrasonic water meter assembly are provided with a second semicircular protection pipe member and a first semicircular protection pipe member from bottom to top, the second semicircular protection pipe member and the first semicircular protection pipe member located on the same side are fixedly connected, the two second semicircular protection pipe members are in conflict with each other, the two first semicircular protection pipe members are in conflict with each other, arc-shaped notches are provided on the same horizontal plane of the two first semicircular protection pipe members, and a regulating and clamping mechanism is provided between the two arc-shaped notches, a second semicircular ring is provided in the regulating and clamping mechanism, and the second semicircular ring is slidably mounted on the first semicircular protection pipe member located at the rear end;

[0008] A linkage mechanism is provided on both sides of the lower end of the second semicircular ring, a linkage shaft is provided on the linkage mechanism, and an extrusion mechanism is provided on both sides of the upper end at the front end, and the two linkage shafts are respectively connected to the two extrusion mechanisms;

[0009] A third semicircular ring is rotatably sleeved in each of the two second semicircular protective pipes, and a synchronous resistance mechanism is provided on the third semicircular ring, and a second resistance plate is provided on the synchronous resistance mechanism. The two second resistance plates respectively resist on both sides of the horizontal end of the ultrasonic water meter component, and a lifting rod is provided on one of the synchronous resistance mechanisms, and the lifting rod is arranged at the lower end of one of the linkage mechanisms.

[0010] Compared with the prior art, the present application can effectively cover the ultrasonic water meter assembly through the cooperation of two first semicircular protective pipe fittings and two arc-shaped notches, and can effectively shield the ultrasonic water meter assembly through the protective cover plate to complete the protection operation of the ultrasonic water meter assembly, and can effectively achieve the purpose of anti-electromagnetic interference, and can also fully limit the positional relationship between the protective mechanism and the ultrasonic water meter assembly to ensure the protection effect.

[0011] Preferably, the regulating and clamping mechanism includes a screw rod rotatably installed in the arc-shaped notch at the rear end, a first semicircular ring is threadedly sleeved on the screw rod, the first semicircular ring is located at the upper end of the second semicircular ring, the first semicircular ring and the second semicircular ring are fixedly connected, the first semicircular ring and the inner wall of the arc-shaped notch at the rear end are in conflict, two nuts are threadedly sleeved on the upper end of the screw rod, the first semicircular ring is located between the two nuts, a closed conflicting mechanism is provided on the first semicircular ring, two spring members are jointly fixed to the first semicircular ring and the bottom located in the arc-shaped notch at the rear end, oblique rod members are fixed on both sides of the lower end of the first semicircular ring, grooves are opened on both sides of the lower end of the arc-shaped notch at the front end, and the lower ends of the two oblique rod members extend into the two grooves respectively.

[0012] Furthermore, by controlling the rotation direction of the screw, the first semicircular ring can be raised and lowered stably. As the first semicircular ring rises and falls, the closed resistance mechanism can be controlled to control whether the protective cover plate can rotate. At the same time, by moving the inclined rod downward, the two first semicircular protective pipe fittings can be moved relative to each other, thereby effectively covering the ultrasonic water meter assembly.

[0013] Preferably, an interference shaft is installed in the groove, and the oblique rod and the interference shaft are in conflict with each other.

[0014] Furthermore, it is possible to facilitate the downward movement of the oblique rod and improve the quality of the relative movement of the two first semicircular protective pipes.

[0015] Preferably, the closed interference mechanism includes two columns fixed on one side of the first semicircular ring, a protective cover plate is hinged on the arc-shaped notch at the rear end, and a first interference plate is fixed to one side of the protective cover plate and the upper ends of the two columns.

[0016] Furthermore, the lifting and lowering of the first semicircular ring can drive the column and the first contact plate fixed on the column to lift and lower. When the first contact plate descends, the two first contact plates can be separated to facilitate the rotation of the protective cover. When the two first contact plates conflict with each other, the protective cover cannot rotate.

[0017] Preferably, the linkage mechanism includes two pressure rods fixed on both sides of the lower end of the second semicircular ring, and the lower ends of the two pressure rods are fixed with square frames, and a rotating shaft is installed in the square frame. Support frames are fixed on both sides of the upper end of the second semicircular protective pipe at the rear end, and the two linkage shafts are rotatably sleeved on the two support frames respectively. A rocker arm is fixed on one side of the linkage shaft, and one end of the rotating shaft is rotatably sleeved on the rocker arm on the same side thereof, and the upper end of the lifting rod is fixed to the lower end of one of the square frames.

[0018] Furthermore, as the first semicircular ring descends, the second semicircular ring can be lowered, so that the pressure rod member pushes the square frame member to descend. Through the descent of the square frame member, the rotating shaft can move inside the square frame member, so that the rocker rod drives the linkage shaft to rotate, and the extrusion mechanism can be operated to ensure that the two first semicircular protective pipes and the two arc-shaped notches are fully in contact with each other.

[0019] Preferably, the extrusion mechanism includes two U-shaped frames fixed on both sides of the upper end of the second semicircular protective tube located at the front end, the front ends of the two linkage shafts pass through the U-shaped frames and extend to the front end of the U-shaped frames, and a rotating rod is fixed to one end of the linkage shaft extending out of the U-shaped frame, and a shaft kit is rotatably sleeved on the rotating rod, and the shaft kit and the front end of the U-shaped frame are in conflict.

[0020] Furthermore, as the linkage shaft rotates, the rotating rod and the shaft kit can be deflected, and at the same time, the shaft kit and the U-shaped frame can be in conflict, so that the shaft kit can be rotated, and the two arc-shaped notches can move relative to each other, thereby increasing the force of mutual squeezing and ensuring the firmness of the connection.

[0021] Preferably, the synchronous interference mechanism includes a push rod rotatably connected to the third semicircular ring, the second interference plate is slidably installed in the corresponding second semicircular protective pipe fitting, the third semicircular ring and one end of the second interference plate are rotatably connected, one end of the push rod is rotatably connected to one side of the second interference plate, and the two second interference plates are respectively located on both sides of the ultrasonic water meter assembly, and a pull rod is rotatably connected to the top of one of the third semicircular rings, a pin is fixed to the lower end of the pull rod, and the end of the pin away from the pull rod is rotatably sleeved on the lower end of the lifting rod, and the lower end of the lifting rod is located in the second semicircular protective pipe fitting.

[0022] Furthermore, when the linkage shaft drives the rocker arm to deflect, the rocker arm will squeeze the lifting rod, which will enable the lifting rod to drive the third semicircular ring to deflect through the pull rod. The third semicircular ring will push another third semicircular ring to rotate, which will enable the third semicircular ring to push the second resistance plate to move through the push rod, and the two second resistance plates will clamp the ultrasonic water meter assembly, thereby limiting the positional relationship between the two second semicircular protective pipes and the ultrasonic water meter assembly and ensuring the overall firmness.

[0023] Preferably, sealing rubber pads are fixed on the arc-shaped notch and the inner wall of the second semicircular protective pipe.

[0024] Furthermore, the sealing rubber pads can be squeezed against each other and easily deformed, thereby effectively ensuring the sealing effect.

[0025] Preferably, both ends of the second semicircular protective tube are fixed with abutting rubber rings, and the lower ends of the two second semicircular protective tubes are hinged to each other.

[0026] Furthermore, the horizontal end of the ultrasonic water meter assembly can be clamped by the effect of the resisting rubber ring, so as to preliminarily ensure the relative position relationship between the second semicircular protective pipe fitting and the ultrasonic water meter assembly.

[0027] Preferably, the lower end of the oblique rod is hemispherical.

[0028] Furthermore, the oblique rod is arranged obliquely, and can quickly collide with the abutment shaft through the hemispherical arrangement, so that the oblique rod can be inserted into the groove.

[0029] The beneficial effects of the present invention are:

[0030] 1. By controlling the rotation direction of the screw, the first semicircular ring can be stably lifted and lowered. As the first semicircular ring is lifted and lowered, the closed resistance mechanism can be controlled to control whether the protective cover plate can rotate. At the same time, by moving the oblique rod downward, the two first semicircular protective pipes can be relatively moved, effectively covering the ultrasonic water meter assembly;

[0031] 2. It is easy to move the inclined rod downward, so that the two first semicircular protective pipes move relatively. At the same time, the inclined rod is tilted, and the hemispherical setting can quickly collide with the conflicting shaft so that the inclined rod can be inserted into the groove;

[0032] 3. The lifting and lowering of the first semicircular ring can drive the column and the first contact plate fixed on the column to lift and lower. When the first contact plate descends, the two first contact plates can be separated to facilitate the rotation of the protective cover. When the two first contact plates conflict with each other, the protective cover cannot rotate.

[0033] 4. As the first semicircular ring descends, the second semicircular ring can be lowered, so that the pressure rod pushes the square frame to descend. Through the descending of the square frame, the rotating shaft can move in the square frame, so that the swing rod drives the linkage shaft to rotate, and the extrusion mechanism can operate to ensure that the two first semicircular protective pipes and the two arc-shaped notches fully contact each other;

[0034] 5. As the linkage shaft rotates, the rotating rod and the shaft kit can be driven to deflect, and at the same time, the shaft kit and the U-shaped frame can be made to collide, so that the shaft kit can be rotated, and the two arc-shaped notches can move relative to each other, thereby increasing the force of mutual extrusion and ensuring the firmness of the connection;

[0035] 6. When the linkage shaft drives the rocker arm to deflect, the rocker arm will squeeze the lifting rod, which will enable the lifting rod to drive the third semicircular ring to deflect through the pull rod. The third semicircular ring will push another third semicircular ring to rotate, which can enable the third semicircular ring to push the second resistance plate to move through the push rod, and the two second resistance plates can clamp the ultrasonic water meter assembly, thereby limiting the positional relationship between the two second semicircular protective pipes and the ultrasonic water meter assembly and ensuring the overall firmness.

A second semi-circular ring 9 is arranged inside the regulating and clamping mechanism, and the second semi-circular ring 9 is slidably installed at the lower end of the first semi-circular protective pipe fitting 3 located at the rear end.

Along with the lifting and lowering of the first semi-circular ring 6, the closed abutting mechanism can be controlled to control whether the protective cover plate 2 can rotate. At the same time, through the downward movement of the inclined rods 7, the two first semi-circular protective pipe fittings 3 can be relatively moved, effectively performing a wrapping operation on the ultrasonic water meter assembly 1.

[0050] Refer to Figures 2-4, the closing and resisting mechanism includes two columns 20 fixed to one side of the first semi-circular ring 6. One of the upper ends of the arc-shaped notch 4 is hinged with a protective cover plate 2.
