Description

Technical Field

[0001] This utility model relates to the field of electric pressure gauge technology, specifically an electric pressure gauge with digital counting. Background Technology

[0002] In fire water supply and fire hydrant systems, pressure-stabilizing pumps play a crucial role in maintaining stable system pressure. To ensure the normal operation of the system and to avoid damage to equipment caused by frequent starts of the pressure-stabilizing pump, as well as to reduce energy waste, Article 5.3.4 of the "Technical Specification for Fire Water Supply and Fire Hydrant Systems" clearly stipulates that pressure-stabilizing pumps should not be started frequently, and the number of pump starts should not exceed 15 times / hour.

[0003] Electrically connected pressure gauges are widely used in this system to monitor pipeline pressure and control the start and stop of pressure-stabilizing pumps based on the set pressure value. However, most existing electrically connected pressure gauges only have traditional pressure measurement and pressure signal output functions to achieve basic control of pressure-stabilizing pumps, but lack the function of accurately counting the number of times the pressure-stabilizing pump is started in actual operation.

[0004] This deficiency leads to numerous inconveniences and challenges in system operation and management. Maintenance personnel cannot intuitively and accurately know the actual number of times the pressure-stabilizing pump is started within a specific time period, and cannot promptly determine whether the pressure-stabilizing pump is starting abnormally frequently. They can only rely on manual observation and rough estimation, which is not only inefficient but also has a large error margin. It is difficult to meet the requirements of the standard for precise monitoring of the number of times the pressure-stabilizing pump is started. Once the pressure-stabilizing pump starts too frequently due to malfunction or other reasons, if it is not detected and dealt with in time, it may lead to a series of serious consequences, such as shortening the service life of the pressure-stabilizing pump, increasing equipment maintenance costs, and even affecting the reliability and effectiveness of the fire water supply system at critical moments due to abnormal pressure fluctuations, posing a potential threat to fire safety.

[0005] In summary, given the various drawbacks of existing electric pressure gauges lacking digital counting functionality in fire water supply and fire hydrant systems, there is an urgent need to develop an electric pressure gauge with digital counting capabilities to accurately monitor and record the number of times the pressure-stabilizing pump is started, thereby ensuring the stable operation of the fire water supply system and fire safety.

[0006] The purpose of this invention is to provide an electrically connected pressure gauge with digital counting capabilities to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An electrically operated pressure gauge with digital counter includes a main body. A digital counter is mounted on the top of the main body via a connecting rod. The digital counter is electrically connected to the pressure gauge and has a start button and a reset button. A protective mechanism is also provided outside the main body. The protective mechanism includes a protective cover covering the main body and the digital counter, and a cover plate installed on the back of the protective cover.

[0009] As a further embodiment of this utility model: a warning whistle is also installed on the digital counter, and side holes are symmetrically opened on the side wall of the protective cover, with dustproof nets installed in the side holes.

[0010] As a further embodiment of this utility model, the cover plate is detachably mounted on the protective cover by multiple bolts.

[0011] As a further embodiment of this utility model, the protective cover is also provided with an installation hole for the power supply to the pressure gauge main body connector to pass through.

[0012] As a further embodiment of this utility model: the protective cover is also provided with a buffer mechanism, the buffer mechanism including a plurality of buffer units fixedly arrayed on the inner wall of the protective cover, the buffer unit including a pair of buffer springs fixedly installed on the inner wall of the protective cover and a pad installed on the buffer springs.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention integrates the main body of the electric pressure gauge with the digital counter, making it convenient and intuitive to count and monitor relevant data such as the number of times the pressure stabilizing pump starts.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] Example 1

[0023] Please see Figure 1-5 An electrically operated pressure gauge with digital counting capabilities includes a main body 1. A digital counter 2 is mounted on the top of the main body 1 via a connecting rod. The digital counter 2 is electrically connected to the pressure gauge and has a start button 3 and a reset button 4. A protective mechanism is also provided outside the main body 1. The protective mechanism includes a protective cover 5 covering the main body 1 and the digital counter 2, and a cover plate 6 installed on the back of the protective cover 5. A protective cover 7 is hinged to the front of the protective cover 5, and a viewing glass 8 is installed on the protective cover 7. By integrating the main body 1 and the digital counter 2 into one unit, it is convenient and intuitive to count and monitor relevant data such as the number of times the pressure stabilizing pump starts. The protective mechanism not only prevents accidental activation of the buttons on the digital counter 2, but also protects internal components from external environmental interference and damage, improving the practicality and reliability of the entire device. The protective cover 7 and the viewing glass 8 allow operators to easily observe the main body 1 and the digital counter 2 and operate the buttons on the digital counter 2.

[0024] The digital counter 2 is also equipped with a warning whistle 9. The protective cover 5 has symmetrical side holes 10 on its side wall, and a dustproof net 11 is installed in the side hole 10. The warning whistle 9 can sound an alarm when the count reaches a set threshold (such as when the number of times the pressure stabilizing pump starts is close to or exceeds the number specified in the standard), reminding the staff to pay attention to the system status in time and avoid equipment damage or fire protection system failure due to failure to detect abnormalities. The side hole 10 facilitates the transmission of sound, while the dustproof net 11 effectively prevents dust and other impurities from entering the interior of the protective cover 5 through the side hole 10, preventing dust from accumulating on the electric pressure gauge and counter and affecting their normal operation, extending the service life of the device and maintaining its performance stability.

[0025] Preferably, the cover plate 6 is detachably installed on the protective cover 5 by multiple bolts. The detachable bolt installation method allows for quick removal of the cover plate 6 when it is necessary to repair, debug or replace the main body 1 of the electric pressure gauge or the counter, so that the staff can easily access the internal components, improve the efficiency of maintenance and repair, and reduce maintenance costs and difficulties.

[0026] In addition, the protective cover 5 is provided with a mounting hole 12 on the side wall for the power supply to the pressure gauge body 1 to pass through. The design of the mounting hole 12 ensures that while the power supply pressure gauge body 1 is protected by the protective cover 5, its connector can be smoothly connected to external equipment or lines without affecting its normal pressure monitoring and signal transmission functions, thus ensuring the integrity and functionality of the entire system.

[0027] Example 2

[0028] This embodiment is an improvement on embodiment 1, specifically as follows:

[0029] Please see Figure 4 and Figure 5 The protective cover 5 is also equipped with a buffer mechanism, which includes multiple buffer units 13 fixedly arrayed on the inner wall of the protective cover 5. Each buffer unit 13 includes a pair of buffer springs 14 fixedly installed on the inner wall of the protective cover 5 and a pad 15 installed on the buffer springs 14. When the device is subjected to external impact or vibration, the buffer springs 14 can absorb and disperse the impact force, while the pad 15 further buffers and homogenizes the force, effectively protecting the main body 1 of the electric pressure gauge and the digital counter 2 from physical damage, maintaining the normal state of their internal precision structure and circuits, reducing the risk of equipment failure caused by accidental impact or vibration, and improving the survivability and stability of the device in complex environments or scenarios where it may encounter external impact.
