[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, the present invention provides a solenoid valve sealing detection device, including a detection body 1, and also including: a press detection mechanism 2, the press detection mechanism 2 is arranged at the top of the inner cavity of the detection body 1; a control panel body 3, the control panel body 3 is arranged at the top of the front of the detection body 1; a first protective mechanism 4, the first protective mechanism 4 is arranged at the top of the front of the detection body 1 and is located on both sides of the control panel body 3; a fixed cover 5, the fixed cover 5 is arranged in the middle of the top of the detection body 1, and a driving mechanism 6 is arranged inside the fixed cover 5; wherein, the first protective mechanism 4 includes a limit rod 401 arranged at the top of the detection body 1 and located on both sides of the control panel body 3, the surface of the limit rod 401 is slidably connected to the protective cover 402, and the outer side of the limit rod 401 is elastically connected to the surface of the detection body 1 through an elastic member 403.

[0034] When the driving mechanism 6 is in operation, the output end of the driving mechanism 6 will drive the bottom part of the driving mechanism 6 to rotate, thereby releasing the blocking and supporting effect on both sides of the driving mechanism 6. Subsequently, the elastic force of the elastic member 403 will be slowly released, thereby pushing the two protective covers 402 to move toward each other, thereby completely shielding and protecting the outer side of the control panel body 3.

[0035] like Figure 3 As shown, the inner wall of the elastic member 403 is slidably connected to the surface of the limiting rod 401 .

[0036] With the above solution, by providing the limiting rod 401 , when the protective cover 402 moves toward or away from the surface of the protective cover 402 , the elastic member 403 will be limited synchronously when it is extended or contracted.

[0037] like Figure 4 As shown, the driving mechanism 6 includes a movable frame 601, a driving motor 602, a rotating disk 603 and a fixed shaft 604;

[0038] The movable frame 601 is fixedly installed on the top of the protective cover 402, and the top of the movable frame 601 extends to both sides of the inner cavity of the fixed cover 5. The drive motor 602 is fixedly installed in the middle of the top of the fixed cover 5. The fixed shaft 604 is arranged at the output end of the rotating disk 603, and the rotating disk 603 is located in the inner cavity of the fixed cover 5. The fixed shaft 604 is fixedly installed on both sides of the top of the rotating disk 603.

[0039] The above solution is adopted: by providing a fixed shaft 604, when the drive motor 602 is started, the output end of the drive motor 602 will drive the entire rotating disk 603 to rotate, which can realize the opposite movement of the movable frame 601 and the inner movement to release the opposite effect of the movable frame 601.

[0040] like Figure 4 As shown, the interior of the fixed cover 5 is provided with a linkage mechanism 7 located outside the movable frame 601, and the linkage mechanism 7 includes a connecting plate 701, a shielding plate 702, a fixed plate 703 and a linkage arm 704;

[0041] The connecting plate 701 is fixedly installed on both sides of the movable frame 601, the shielding plate 702 is movably installed inside the two sides of the detection body 1, the fixed plate 703 is fixedly installed on the top of the shielding plate 702, and the fixed plate 703 is located inside the fixed cover 5, and the linkage arm 704 is hinged between the inner end of one side of the fixed plate 703 and the outer end of one side of the connecting plate 701.

[0042] The above solution is adopted: by providing a linkage arm 704, the movable frame 601 moves toward each other, which will cause the connecting plates 701 to move toward each other synchronously, and the linkage arm 704 to deflect and push the fixed plate 703 and the shielding plate 702 to move forward as a whole.

[0043] like Figure 4 and Figure 5 As shown, the inner groove on one side of the shielding plate 702 and the ventilation holes on both sides of the detection body 1 have exactly the same size.

[0044] By adopting the above solution: when the inner groove on one side of the shielding plate 702 is aligned with the ventilation holes on both sides of the detection body 1, the heat generated by the operation of the press detection mechanism 2 can be ventilated and dissipated; and when misaligned, the press detection mechanism 2 can be protected when idle.

[0045] like Figure 6 As shown, the interior of the detection body 1 is provided with a hydraulic assembly 8 located at the bottom front end of the shielding plate 702. The hydraulic assembly 8 includes a first hydraulic cylinder 801, a first hydraulic piston rod 802 and a connecting block 803;

[0046] The first hydraulic cylinder 801 is fixedly installed inside the detection body 1, and the first hydraulic cylinder 801 is located on the front side of the bottom of the baffle 702. The first hydraulic piston rod 802 is movably installed in the inner cavity of the first hydraulic cylinder 801. The connecting block 803 is fixedly installed at the output end of the first hydraulic piston rod 802, and the top of the connecting block 803 is fixedly connected to the bottom of the baffle 702.

[0047] With the above solution, when the shielding plate 702 moves forward, the connecting block 803 will move forward synchronously, and the first hydraulic piston rod 802 will be driven forward, thereby pushing the hydraulic oil in the inner cavity of the first hydraulic cylinder 801 out.

[0048] like Figure 8 As shown, the detection body 1 is provided with a power assembly 9 located outside the bottom of the first hydraulic cylinder 801. The power assembly 9 includes a second hydraulic cylinder 901, a second hydraulic piston rod 902, an active gear block 903 and an oil pipe 904.

[0049] The second hydraulic cylinder 901 is fixedly mounted inside the detection body 1 and is located outside the bottom of the first hydraulic cylinder 801. The second hydraulic piston rod 902 is movably mounted in the inner cavity of the second hydraulic cylinder 901. The active gear block 903 is fixedly mounted on the front end of the second hydraulic piston rod 902. The oil pipe 904 is fixedly connected to the rear end of the second hydraulic cylinder 901.

[0050] The other end of the oil pipe 904 is fixedly connected to the front end of the bottom of the first hydraulic cylinder 801.

[0051] The above solution is adopted: by providing an oil pipe 904, when the hydraulic oil in the inner cavity of the first hydraulic cylinder 801 is pushed out by the forward movement of the first hydraulic piston rod 802, it will be introduced into the inner cavity of the second hydraulic cylinder 901 along the inner cavity of the oil pipe 904, so that the hydraulic pressure in the inner cavity of the second hydraulic cylinder 901 becomes larger and pushes the second hydraulic piston rod 902 and the active gear block 903 to move forward as a whole.

[0052] like Figure 8As shown, the second protection assembly 10 is provided on both sides of the front of the detection body 1. The second protection assembly 10 includes a support shaft 101, a protection door 102 and a driven gear 103;

[0053] The support shaft 101 is movably sleeved on both sides of the front end of the detection body 1 , the protective door 102 is fixedly sleeved on the surface of the support shaft 101 , and the driven gear 103 is fixedly sleeved on the surface of the support shaft 101 , and the driven gear 103 is located at the bottom of the protective door 102 .

[0054] With the above solution, by providing the protective door 102 , when the support shaft 101 and the protective door 102 are driven to rotate, the front of the detection body 1 can be shielded and protected.

[0055] like Figure 1 、 Figure 2 、 Figure 5 and Figure 8 As shown, the surface of the driven gear 103 is meshed with the inner side of the driving gear block 903 .

[0056] The above solution is adopted: by providing a driven gear 103, when the entire active gear block 903 is driven forward, the teeth on the inner side of the active gear block 903 will drive the teeth on the surface of the driven gear 103, and the driven gear 103, the support shaft 101 and the protective door 102 can be smoothly driven to rotate.

[0057] The working principle and use process of the present invention:

[0058] First, the operator can place the solenoid valve to be tested at the bottom of the detection body 1, control the press detection mechanism 2 to start and press the detection mechanism 2 downward, and completely clamp the two end pipes of the solenoid valve inside the detection device, and then perform the sealing test.

[0059] Then, when the detection body 1 is idle and not in use as a whole, the drive motor 602 can be started, so that the output end of the drive motor 602 drives the rotating disk 603 to rotate, so that the fixed shaft 604 on the top of the rotating disk 603 rotates slowly toward the inside, thereby releasing the shielding and supporting effect on the inside of the movable frame 601, and then the elastic force of the elastic member 403 will be smoothly released, thereby pushing the two protective covers 402 to move toward each other until they are fully fitted to completely shield and protect the control panel body 3.

[0060] At the same time, when the movable frame 601 moves toward each other, it can drive the two connecting plates 701 to move toward each other synchronously, thereby causing the linkage arm 704 to deflect and push the fixed plates 703 and the shielding plates 702 on both sides to move forward synchronously, so that the shielding plates 702 block and seal the vents on both sides of the detection body 1, and the forward movement of the shielding plates 702 will drive the connecting block 803 and the first hydraulic piston rod 802 to move synchronously as a whole, so that the hydraulic oil in the inner cavity of the first hydraulic cylinder 801 is introduced into the inner cavity of the second hydraulic cylinder 901 through the oil pipe 904, so that the hydraulic oil in the inner cavity of the second hydraulic cylinder 901 pushes the second hydraulic piston rod 902 and the active gear block 903 to move as a whole, and through the meshing relationship between the inner side of the active gear block 903 and the surface of the driven gear 103, the driven gear 103, the support shaft 101 and the protective door 102 can be driven to rotate as a whole, so that the protective door 102 deflects to completely block and seal the front of the detection body 1.
