Usually, different support parts are replaced to achieve the connection and measurement between the pressure gauge and the detection point, which may consume a large amount of time and labor costs.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Usually, the components of the embodiments of the present application described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0026] A detection device for a hydraulic system disclosed by the present utility model is mainly applied to the situation that during the long-term navigation of a ship, the hydraulic system will be affected by various factors such as seawater corrosion, vibration, and temperature change, resulting in performance degradation or even failure. Therefore, it is necessary to regularly detect the ship's hydraulic system to maintain the normal operation of the ship. The pressure values at various points in the hydraulic system are detected through a pressure gauge to ensure that they are within the normal range. However, most of the support frames of the existing pressure gauges are fixed and cannot flexibly adjust their heights according to the detection points with different heights and different layouts. Usually, different support parts are replaced to achieve the connection and measurement between the pressure gauge and the detection point, which may consume a large amount of time and labor costs.

[0027] Refer to Figure 1 、 Figure 3 and Figure 4A detection device for a hydraulic system includes a detection element interface 1 and a pressure gauge 6. The outer wall of the detection element interface 1 is provided with a valve and two support frames 5. The valve is fixedly connected to the pressure gauge 6. The device also includes:

[0028] Lifting mechanism: Located on one side of the pressure gauge 6, the lifting mechanism includes two rotary cover plates 3, two tooth plates 18 and two rotary blocks 14. A gear 13 is provided on the outer wall of one side of the rotary cover plate 3. The rotary block 14 penetrates the outer wall of one side of the rotary cover plate 3, and a mounting rod 16 and a connecting block are provided on the circumferential outer wall of the rotary block 14. The connecting block is hinged with a connecting buckle 15, one end of the connecting buckle 15 is engaged with the teeth on the gear 13, and one side of the outer wall of the rotary block 14 is connected to a fixing frame 20 through a bearing. A limiting ring 17 is provided on the outer wall of the rotary cover plate 3 away from the gear 13. The limiting ring 17 is located between two adjacent teeth on the tooth plate 18;

[0029] Protection mechanism: located on the outer wall of the pressure gauge 6;

[0030] Cleaning mechanism: located on one side of the pressure gauge 6.

[0031] The fixing frame 20 is fixedly connected to an inner wall of one side of the supporting frame 5 , so as to provide support and limit functions for the rotary cover plate 3 and the lifting mechanism.

[0032] During specific use, the limiting ring 17 is a vortex structure. When the limiting ring 17 rotates clockwise or counterclockwise, it cooperates with the teeth on the tooth plate 18 to control the tooth plate 18 to rise or fall.

[0033] Among them, one end of the connecting buckle 15 is an "L"-shaped structure. This arrangement makes it easy for the connecting buckle 15 to move the teeth on the gear 13 as the mounting rod 16 is pried, thereby driving the gear 13, the rotary cover plate 3 and the limit ring 17 to rotate.

[0034] Specifically, when testing the hydraulic system, the pressure gauge 6 is first installed on the valve, and then the protective mechanism is used to protect the outer wall of the pressure gauge 6, and then the mounting rod 16 is pried, so that one end of the connecting buckle 15 drives the gear 13 to rotate, and at the same time, the rotary cover plate 3 is driven to rotate. The rotation of the rotary cover plate 3 drives the limiting ring 17 of the back spiral to cooperate with the teeth on the toothed plate 18, thereby realizing the up and down movement of the toothed plate 18 in the support frame 5. The setting of the connecting buckle 15 can control the rise and fall of the toothed plate 18, and also has a braking function to prevent the toothed plate 18 from falling. Then, according to the connection height between the valve and the pressure gauge 6, the height of the toothed plate 18 in the support frame 5 is adjusted. This device can flexibly adjust the height of the toothed plate 18 on the support frame 5 according to the distance between the pressure gauge 6 and the valve of the detection element interface 1, thereby improving its practicality and flexibility and reducing time and manpower cost investment.

[0035] Reference Figure 1 and Figure 2 , in a preferred embodiment, the protection mechanism includes two protection covers 2 and a transparent protection plate 10. The protection covers 2 are snap-fitted on the outer side of the pressure gauge 6. Three return springs 7 are provided on the inner wall of the protection cover 2. The three return springs 7 are evenly distributed. An installation ring 8 is provided on the outer wall of one side of the two protection covers 2. A threaded groove is provided on the inner circumferential wall of the installation ring 8. The transparent protection plate 10 is threadedly connected to the inner wall of the threaded groove.

[0036] Among them, a support rod 4 is provided on the outer circumferential wall of the protection cover 2. A connecting plate 19 is provided on the outer wall of one side of the toothed plate 18. One end of the support rod 4 is connected to the outer wall of one side of the connecting plate 19. Such a setting facilitates the toothed plate 18 on the support frame 5 to synchronously adjust the height of the support rod 4 according to the height positions of the protection cover 2 and the pressure gauge 6. The support rod 4 can provide support and limit functions for the protection cover 2 and the pressure gauge 6.

[0037] Specifically, the protection cover 2 is snap-fitted on the outer side of the pressure gauge 6. The two protection covers 2 are both arc-shaped half-rings covering the outer wall of the pressure gauge 6. Then the connection part of the two protection covers 2 is fixed by bolts. The provided transparent protection plate 10 facilitates viewing the value while protecting the pressure gauge 6, avoids the pressure gauge 6 being separated from the valve due to collision, and facilitates the pressure gauge 6 to detect the pressure inside the detection element interface 1. The provided return spring 7 mainly buffers the vibration generated by the impact of the outside world on the pressure gauge 6, and improves the accuracy of the pressure detection value of the pressure gauge 6 for the detection element interface 1.

[0038] Reference Figure 1 and Figure 2 , in a preferred embodiment, the cleaning mechanism includes a scraping rod 12. A limiting groove 9 is provided on the outer wall of one side of the installation ring 8. The scraping rod 12 is hinged on the outer wall of the transparent protection plate 10 near the central position. A moving block 11 is provided at one end of the scraping rod 12. The moving block 11 is slidably connected to the inner wall of the limiting groove 9.

[0039] Specifically, when there is oil stain or dust on the surface of the transparent protection plate 10, the scraping rod 12 can be rotated. The scraping rod 12 takes the central position of the transparent protection plate 10 as the center of the circle. Then one end of the scraping rod 12 drives the moving block 11 to slide in the limiting groove 9 and make a circular motion, so as to scrape off the dust on the surface of the transparent protection plate 10.

[0040] Working principle: When detecting a hydraulic system, first install the pressure gauge 6 on the valve, then use the protection mechanism to protect the outer wall of the pressure gauge 6, and then pry the installation rod 16, so that one end of the connecting buckle 15 drives the gear 13 to rotate, and at the same time, it will also drive the rotary cover plate 3 to rotate. The rotation of the rotary cover plate 3 will drive the limit ring 17 on the back helix to cooperate with the teeth on the tooth plate 18, so as to realize the up and down movement of the tooth plate 18 in the support frame 5. The setting of the connecting buckle 15 can control the rise and fall of the tooth plate 18, and also has a braking function to prevent the tooth plate 18 from falling. Then, according to the connection height between the valve and the pressure gauge 6, the height of the tooth plate 18 in the support frame 5 is adjusted.
