A precise remote pressure gauge

Abstract

This utility model discloses a remote pressure gauge with high accuracy, comprising a gauge body, a pointer and a tactile sensor on the front of the gauge body, a power supply and a horn on each side of the gauge body, a Hirschmann junction box at the bottom of the horn, an observation component, a mounting box, and a limiting component. The observation component and the mounting box are located on the front of the Hirschmann junction box, and the limiting component is inserted into the side of the mounting box. This utility model utilizes the design of the observation component, mounting box, and limiting component. When the pointer passes the tactile sensor, the current supplied by the power supply flows into the horn, causing the horn to emit an alarm sound. At this time, the ammeter detects the magnitude of the current flowing through the horn and displays the current value. By comparing the current value with the current value when the horn is in normal use, the power supply capacity can be estimated, allowing for timely replacement of the power supply and ensuring the alarm effect of the gauge.

Description

Technical Field

[0001] This utility model relates to the field of pressure gauge technology, and in particular to a remote pressure gauge with accurate measurement. Background Technology

[0002] Remote pressure gauges are suitable for measuring the pressure of liquids, steam, and gases that do not corrode steel and copper alloys. They can transmit the measured value as an electrical value to a secondary instrument located far from the measuring point to achieve centralized detection and remote control.

[0003] The remote pressure gauge, with announcement number CN209623946U, includes a pressure gauge body, a Hirschmann junction box, a pressure sensor, an integrated module, a movement, and a Bourdon tube. The inner cavity of the pressure gauge body contains, from the inside out, a dial, tempered glass, and a face cover. The face cover is movably snapped into the pressure gauge body, and a sealing ring is fixedly connected at the snap-fit ​​point. The tempered glass is fixedly connected between the dial and the face cover. The index on the dial gradually increases clockwise. A first tactile sensor is fixedly connected to the upper right corner of the dial. This invention, through the design of the pointer, indicator light, power supply, first horn, second horn, first tactile sensor, and second tactile sensor, achieves a simple structure, ease of use, and good warning effect. During use, it effectively improves the safety of the remote pressure gauge, providing protection for the personal safety of personnel.

[0004] When the pointer passes through the first tactile plate, an alarm can be triggered by the first horn to maintain the pressure gauge. However, the entire alarm device requires power from a power source located on one side of the pressure gauge. Over time, the power will gradually decrease. When the power storage is low, the first horn will not be able to emit a sufficient sound to trigger the alarm when the pointer passes through the first tactile plate, thus affecting the use of the remote pressure gauge.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides, for example Figure 1-7The diagram shows a remote pressure gauge with high accuracy, comprising a gauge body 1, a pointer 2 on the front of the gauge body 1, a tactile sensor 3 on the front of the gauge body 1, a power supply 4 and a horn 5 on each side of the gauge body 1, and a Hirschmann junction box 6 for mounting the horn 5 at the bottom. It also includes:

[0032] Observation component 7 is located on the front of the Hirschmann junction box 6 and is used to detect the current of the speaker 5.

[0033] Mounting box 8 is located on the front of Hirschmann junction box 6 and is used to observe the installation of component 7.

[0034] Restriction 9 is interposed on the side of the mounting box 8 and is used to restrict the movement of the observation component 7.

[0035] One end of the Hirschmann junction box 6 is fixedly connected to the outer wall of the meter body 1, and the bottom end of the speaker 5 is fixedly connected to the top end of the Hirschmann junction box 6.

[0036] Furthermore, the gauge body 1, pointer 2, tactile contact plate 3, power supply 4, horn 5, and Hirschmann junction box 6 correspond to the pressure gauge body, pointer, first tactile contact plate, first horn, and Hirschmann junction box in announcement number CN209623946U, respectively. An indicator light is also provided on the top of the gauge body 1. Its working principle is similar to that of the remote pressure gauge in CN209623946U. When the gauge body 1 starts working and the pressure is too high, the pointer 2 will rotate clockwise. When the pointer 2 rotates to the position of the tactile contact plate 3 and they make contact (first critical point), the pointer 2 will quickly transmit the current in the power supply 4 through the pointed metal conductor and wire to the current receiving port of the indicator light. When the indicator light is powered on, the indicator light will light up, and the pointer 2 will transmit the current to the terminal on the horn 5. When the horn 5 is powered on, the horn 5 will start to emit a sound. When the staff hears the sound emitted by the horn 5, they can effectively observe the position of the indicator light and quickly take action to eliminate safety hazards. Through the accurate measurement of pressure by the remote pressure gauge, the protection of the remote pressure gauge is achieved.

[0037] The back of the mounting box 8 is fixedly connected to the front of the Hirschmann junction box 6. The front of the mounting box 8 has a mounting slot for mounting the observation component 7, and the mounting slot is connected through the Hirschmann junction box 6.

[0038] The observation component 7 includes an ammeter 71, with a snap-fit ​​plate 72 fixedly connected to the side of the ammeter 71, and the ammeter 71 is inserted into the mounting slot.

[0039] Limiting component 9 includes:

[0040] The limiting block 91 is disposed inside the mounting groove, and the side of the inner wall of the mounting groove is provided with a moving groove for the limiting block 91 to move.

[0041] Pull rod 92 is located on the outside of mounting box 8 and is used for hand gripping;

[0042] Linkage rod 93 is disposed between limiting block 91 and pull rod 92, and is used to connect limiting block 91 and pull rod 92.

[0043] The horizontal cross-section of the limiting block 91 is a right trapezoid, with the inclined surface of the right trapezoid facing away from the side of the Hessmann junction box 6.

[0044] The mounting box 8 has an internal cavity, and the inner wall of the cavity has a round hole for inserting the linkage rod 93. The outer wall of the linkage rod 93 is fixedly fitted with a baffle 94 for restricting the movement of the linkage rod 93. The outer side of the linkage rod 93 is fitted with an elastic sleeve 95 for pushing the baffle 94. Both the baffle 94 and the elastic sleeve 95 are located inside the cavity.

[0045] Furthermore, the ammeter 71 and the snap-fit ​​plate 72 constitute the existing D85-240T digital display miniature ammeter. The ammeter 71 is connected in parallel with the circuit of the horn 5, so the current flowing through the horn 5 is detected by the ammeter 71, thereby displaying the magnitude of the current flowing through the horn 5. The snap-fit ​​plate 72 is an elastic snap-fit ​​plate. One end of the snap-fit ​​plate 72 is fixedly connected to the outer wall of the ammeter 71, and the other end is protruding, used to abut against the limiting member 9, thereby restricting the movement of the ammeter 71 inside the mounting box 8. Two snap-fit ​​plates 72 are symmetrically arranged, located on both sides of the outer wall of the ammeter 71. The number of limiting members 9 corresponds to the number of snap-fit ​​plates 72. The mounting box 8 and the Hirschmann junction box 6 are connected by adhesive, and the mounting box 8 and the Hirschmann junction box 6 are connected through, thereby connecting the circuit of the ammeter 71 to the horn. The circuit of 5 is connected, and the two ends of the linkage rod 93 are respectively glued and fixed to the opposite side of the pull rod 92 and the limiting block 91. The size of the round hole corresponds to the diameter of the linkage rod 93. The size of the baffle 94 is 1.2 times the size of the round hole. The elastic sleeve 95 is always in a compressed state in the cavity, so the elastic sleeve 95 pushes the baffle 94 to move closer to the ammeter 71, so that the limiting block 91 protrudes out of the moving groove. The right angle side of the limiting block 91 contacts the protruding part of the snap-fit ​​plate 72 to form a snap-fit, preventing the snap-fit ​​plate 72 from moving, thus realizing the installation of the ammeter 71 and the mounting box 8. When it is necessary to remove the ammeter 71, the pull rod 92 is pulled away from the mounting box 8. The pull rod 92 drives the linkage rod 93 to move the limiting block 91 into the moving groove, so that the ammeter 71 can be removed.

[0046] A protective cover 10 for shielding the pull rod 92 is fixedly connected to the side of the outer wall of the mounting box 8.

[0047] Furthermore, the protective cover 10 is bonded and fixed to the outer wall of the mounting box 8 to cover the pull rod 92 and the round hole, thereby preventing external rainwater from entering the interior of the mounting box 8.

[0048] When the remote pressure gauge is in use, when the pointer 2 passes the sensor 3, the current from the power supply 4 will flow through the horn 5, causing it to sound an alarm. At the same time, the current from the power supply 4 will also flow through the ammeter 71, which will display the current value. The operator can compare the current value with the normal operating current value of the horn 5 to determine the remaining power of the power supply 4 and perform replacement or maintenance.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
