Description

Technical Field

[0001] The utility model relates to the technical field of pressure detection, in particular to an intelligent pressure meter. Background Art

[0002] The pressure tester is suitable for pressure resistance and pressure holding tests using helium and nitrogen as the test media, as well as vacuum pressure holding tests. It is used in refrigeration, air conditioning and other production workshops that require inflation pressure tests and vacuum leak tests, which will greatly improve production efficiency, improve the scientific nature of product process inspections, and save labor costs.

[0003] The application number in the existing public technology is: CN202022344422.4. A buried wireless intelligent pressure detector for smart gas engineering. When used on rainy days, the rainwater will be collected on the operating box through the squeezing water inlet device, and the rainwater will react with calcium carbide particles to generate a large amount of gas. Under the action of the gas pressure inside the operating box, the protective plate on the fixed pipe is pushed toward the heat dissipation holes on the detector to move, forming an automatic rain protection mechanism to prevent rainwater from entering the detector through the heat dissipation holes and causing damage to it.

[0004] However, the above patent still has certain shortcomings when in use: it realizes the movement of the protective plate by reacting calcium carbide particles with water to generate gas, but the number of calcium carbide particles that can be accommodated in the device is limited, and in daily use, it will also come into contact with external moisture and water vapor, which will cause silicon carbide to "deteriorate", making its effect on rainy days very limited, so that the protective plate cannot be moved smoothly, and the heat dissipation holes cannot be smoothly shielded, resulting in the overall protective effect being less than ideal, causing rainwater to still invade the detector and cause impact, and the overall heat dissipation form is relatively single. When the air outlet heat dissipation is blocked by the protective plate on rainy days, the heat dissipation cannot be efficiently carried out, making the overall heat dissipation effect less than ideal, thereby affecting the overall use effect.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0020] (1) The utility model adopts a water collecting trough and a water cooling pipe. When the device is used on a rainy day, the protective cover can protect the heat dissipation holes on the surface of the device, thereby preventing rainwater from invading and damaging the device.

When used on rainy days, the humidity sensor and the rainfall sensor in the sensor assembly can detect whether it is raining around. When rain is detected, the protective plate can be pushed down as a whole by the electric push rod, and then the protective plate is moved to the heat dissipation hole. At this time, the protective plate can block the space around the heat dissipation hole, thereby avoiding direct intrusion of rainwater. The device can ensure timely rain protection through the intelligent structure setting of the sensor assembly and the electric push rod, thereby improving the overall use effect and having the advantage of timely rain protection.

[0032] In one embodiment, guide grooves 8 for the movement of the protective plate 2 are symmetrically provided on both sides of the heat dissipation hole 12 on the surface of the intelligent pressure tester body 1. The guide grooves 8 are provided to limit the movement trajectory of the protective plate 2 to ensure the stability and accuracy of its movement.

[0033] In one embodiment, grooves for gas circulation are provided on the surface of the protective plate 2 and the surface of the protective cover 9. The grooves are provided to facilitate the smooth discharge of hot air discharged from the heat dissipation holes 12 when shielding.

[0034] In one embodiment, the size of the protective plate 2 is larger than the distribution size of the heat dissipation holes 12. The size of the protective plate 2 is set to fully cover the heat dissipation holes 12, thereby preventing the intrusion of rainwater from the outside when used on rainy days.

[0035] In one embodiment, a docking joint 13 is installed at the bottom of the intelligent pressure tester body 1. The docking joint 13 is provided to facilitate connection with the object to be tested, thereby facilitating subsequent testing operations.

[0036] In one embodiment, a sensor assembly 5 is installed in the middle position of the top surface of the intelligent pressure tester body 1. The sensor assembly 5 is composed of a rain sensor and a humidity sensor. The sensor assembly 5 is configured to detect rainfall and humidity in the surrounding environment, so as to facilitate timely movement of the protective plate 2, so that it can smoothly block the heat dissipation hole 12 to facilitate the intrusion of rainwater.

[0037] In one embodiment, the protective cover 9 is made of metal material, and the metal material can be adjusted according to needs, such as aluminum alloy material, and targeted anti-corrosion treatment can be performed on its surface, such as spraying anti-corrosion paint, etc., to enhance the anti-corrosion effect and extend the service life.

[0039] Working principle: In actual use, the user first connects the joint 13 to the gas pipeline, and then the gas is transported to the inside of the joint 13 through the gas pipeline and finally enters the inside of the intelligent pressure tester body 1, through the internal gas pressure sensor (the basic working principle of the gas pressure sensor is to input a liquid medium, such as liquid, gas, mixed gas, etc., into a closed container to achieve a pressure change in the container, so that a special type of piezoresistive piece installed in the sensor is deformed, thereby causing a specific voltage output, thereby detecting the pressure change of the liquid medium. Due to the variety of types of gas pressure sensors, their working principles will also be correspondingly different, and the working principles The principle and structure are mature technologies, so they are not described in detail) to test the gas pressure, and then the test data is transmitted to the control terminal inside the intelligent pressure tester body 1 through the pressure sensor, and then the data can be displayed on the display screen on the surface of the intelligent pressure tester body 1 for the user to view. Then, when it is used on rainy days, the humidity sensor and the rainfall sensor in the sensor assembly 5 can be used to detect whether it is raining around. When rain is detected, the protective plate 2 can be driven to move downward as a whole through the ejection of the electric push rod 7, and then the protective plate 2 is moved to the heat dissipation hole 12. At this time, the protective plate 2 can be blocked to The space around the heat dissipation hole 12 is shielded to prevent direct intrusion of rainwater. Then a protective cover 9 is provided on the side of the protective plate 2. The hot air discharged from the heat dissipation hole 12 can be normally guided out through the slots inside the protective cover 9, thereby realizing the heat dissipation operation. At the same time, part of the falling rainwater around will be collected by the water collecting cover 4, and the other part will directly drip on the protective cover 9. At this time, the water guide groove 10 on the surface of the protective cover 9 can increase the contact area between the rainwater and the protective cover 9, so that the heat transferred from the heat dissipation hole 12 can be taken away by the rainwater, thereby reducing the temperature around the heat dissipation hole 12, so that the heat in the heat dissipation hole 12 can be dissipated through the temperature difference. It can be discharged continuously and efficiently, and the rainwater collected by the water collecting cover 4 can flow into the water cooling pipe 15 through the water supply hose 6, and the water cooling pipe 15 is arranged inside the protective cover 9. Through the continuous flow of rainwater inside the water cooling pipe 15, the temperature of the surface of the protective cover 9 can be increased, and then the heat discharged from the heat dissipation hole 12 can be more fully absorbed, so as to avoid the accumulation of heat causing the temperature inside and outside the heat dissipation hole 12 to be the same, resulting in the heat being unable to be discharged normally. By using a plurality of groups of different heat dissipation structures in coordination, the overall heat dissipation effect on rainy days can be effectively improved, which is convenient for better use. The device as a whole has the advantages of timely rain protection, good heat dissipation on rainy days, and various heat dissipation forms.
