Description

Technical Field

[0001] The utility model belongs to the technical field of oil pressure gauge protection equipment, in particular to an oil pressure gauge protection device for a strong oil-water cooler. Background Art

[0002] Oil cooler is a kind of oil cooling equipment commonly used in hydraulic system and lubrication system. It can realize heat exchange between two fluid media with a certain temperature difference, so as to reduce the oil temperature and ensure the normal operation of the system.

[0003] At present, oil pressure gauges and water pressure gauges are generally arranged on the forced oil-water-cooled coolers for transformers. When the coolers are inspected and maintained on a daily basis, the staff may easily touch the oil pressure gauge. Although it seems normal at the time, the threads of the oil pressure gauge are actually slightly loose, and the loose parts often leak oil after one or two days. In addition, when operating in summer, the cylindrical outer wall surface of the forced oil-water-cooled cooler is prone to form a large amount of condensed water with the air, which then drips onto the oil pressure gauge, causing the metal parts of the oil pressure gauge to rust and be damaged, greatly reducing the life of the oil pressure gauge, affecting the stable operation of the equipment, and bringing hidden dangers to the safe and stable operation of the power system.

[0004] The utility model patent with application number CN202020707030.7 discloses a new type of hydraulic oil level gauge, which protects the oil level gauge of the transformer in the substation by setting a protective cover and a cover plate to prevent the oil level gauge from directly contacting the outside air. The application steps of this patent are cumbersome. When it is necessary to observe the oil pressure gauge, the oil pressure gauge must be removed from the protective cover before reading, which is time-consuming and laborious; and the patent completely encloses the oil pressure gauge in the protective cover, but in the actual use of the oil pressure gauge of the oil-water-cooled cooler, it is sometimes necessary to operate the handle on the oil pressure gauge to adjust the oil pressure gauge. If the protective cover of this patent is used, not only can the oil pressure gauge not be observed at any time, but the oil pressure gauge cannot be adjusted in time. Therefore, there is an urgent need to provide an oil pressure gauge protection device that can solve the above problems. Utility Model Content

It can be seen from the above structure that the cooler oil pipe 1 has a cylindrical side wall and serves as the basic structure for installing the oil pressure gauge. The transparent shield 2 cooperates with the insulating elastic band 3 and is detachably mounted on the side wall of the cooler oil pipe 1 to provide protection for the oil pressure gauge. The structure is simple and the assembly and disassembly are convenient. The transparent shield 2 is used to cover the oil pressure gauge to protect the oil pressure gauge so that the oil pressure gauge will not be corroded by external condensed water. The cover body of the transparent shield 2 is transparent and will not block the indication on the oil pressure gauge, which is convenient for the staff to observe the state and reading of the oil pressure gauge. The transparent shield 2 includes a shield top wall, a shield front wall, a shield left wall, a shield right wall and a shield rear wall. The shield top wall is connected to the shield front wall, the shield left wall, the shield right wall and the shield rear wall to form a complete transparent shield 2. The shield front wall is provided with a first channel connecting the inside of the transparent shield 2 with the outside. The first channel is used to install the handle of the oil pressure gauge provided on the cooler oil pipe 1 outside the transparent shield 2. While the transparent shield 2 protects the oil pressure gauge, it can also ensure that the handle of the oil pressure gauge can be operated normally during operation.

When installing the utility model, the operator can first cover the transparent shield 2 outside the oil pressure gauge, then stretch the insulating elastic band 3, and then make the side wall of the cooler oil pipe 1 between the transparent shield 2 and the insulating elastic band 3. Since the insulating elastic band 3 has a certain elastic deformation ability, the operator can further adjust the transparent shield 2 to a suitable installation position, and then let go, so that the insulating elastic band 3 contacts and tightens the side wall surface of the cooler oil pipe 1 to fix the installation position of the transparent shield 2. The utility model can provide protection for the oil pressure gauge of the strong oil-water cooling cooler, so that the oil pressure gauge will not be corroded by external condensed water, and the service life of the oil pressure gauge can be extended.
