[0038] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0039] Embodiment:

[0040] Referring to Figure 1 , Figure 2 and Figure 3 , the present embodiment discloses a kind of extraction tank installed with safety detection device, including tank body 10, cover body 20, pressure measuring assembly 30 and warning assembly 40. Wherein, the bottom of tank body 10 is discharge port 11, hinge 12 is arranged on one side of discharge port 11, clamping groove 13 is arranged on the other side of discharge port 11.

[0041] One side of cover body 20 is connected with hinge 12, so that cover body 20 can rotate at the bottom of tank body 10 discharge port 11, the other side of cover body 20 is provided with connecting piece 21, the connecting piece 21 can be connected with clamping groove 13, so as to install cover body 20 on the bottom of tank body 10, and cover body 20 completely covers discharge port 11.

[0042] Pressure measuring assembly 30 is arranged on cover body 20, and warning assembly 40 is arranged on pressure measuring assembly 30. Since cover body 20 is a kind of relatively easy to disassemble component on tank body 10, the cover body 20 is directly transformed, the installation difficulty can be reduced, and the tank body 10 can be most effectively visualized monitored to obtain working pressure.

[0043] Specifically, first, a pressure measuring hole is formed in the cover body 20, and a pressure measuring pipe 33 is arranged in the pressure measuring hole, so that one end of the pressure measuring pipe 33 is arranged on the pressure measuring hole and can communicate with the inside of the tank body 10, and the other end of the pressure measuring pipe 33 is closed, so that when the pressure in the tank body 10 increases, the pressure in the pressure measuring pipe 33 will also increase. The above-mentioned pressure measuring assembly 30 includes pressure measuring pipe 33, and the pressure measuring pipe 33 is connected with a magnetic induction element and a warning assembly 40.

[0044] The pressure in the pressure measuring pipe 33 can be measured by the magnetic induction element, and an alarm can be issued by the warning assembly 40 when the pressure exceeds the pressure limit.

[0045] In the embodiment, the magnetic induction element comprises a piston 31 and a movable plate 32, wherein the piston 31 is arranged in the pressure measuring tube 33 and is movable in the pressure measuring tube 33, and after the piston 31 is arranged in the pressure measuring tube 33, the space on one side of the piston 31 is a closed space and the space on the other side is an open space and the space on the other side can communicate with the inside of the tank body 10.

[0046] In a normal case, i.e. when the pressures on both sides of the piston 31 are the same, the piston 31 is close to the pressure measuring hole, so that the closed space on the other side of the piston 31 has a large enough movable space.

[0047] In addition, the piston 31 is provided with a magnet.

[0048] The movable plate 32 is made of a magnetic material, such as iron, so that the movable plate 32 can be attracted by the piston 31. The movable plate 32 is movably connected to the cover body 20, and when the piston 31 is close to the movable plate 32, the movable plate 32 is attracted to the pressure measuring tube 33, so that the warning assembly 40 is triggered by the movement of the movable plate 32.

[0049] In the embodiment, the triggering element of the warning assembly 40 is arranged close to the movable plate 32.

[0050] In one specific embodiment:

[0051] The warning assembly 40 comprises a contact switch 41, a warning light 42 and a siren 43, wherein the contact switch 41 is the triggering element of the warning assembly 40, so the contact switch 41 is arranged close to the movable plate 32 and can be touched by the movable plate 32.

[0052] The warning light 42 and the siren 43 are electrically connected to the contact switch 41, and when the contact switch 41 is touched, the warning light 42 and the siren can both play a warning role through sound and light.

[0053] Specifically, a support rod 34 is arranged on the cover body 20 and located at the side of the pressure measuring tube 33, and the movable plate 32 is movably arranged on the support rod 34. The contact switch 41 of the warning assembly 40 and the movable plate 32 are installed on the support rod 34.

[0054] In another specific embodiment:

[0055] One support rod 34 is arranged on each side of the pressure measuring tube 33, and one support plate 35 is arranged on the ends of the two support rods 34 away from the cover body 20.

[0056] The movable plate 32 described above is located between the two support rods 34, and the movable plate 32 can move along the length direction of the support rods 34.

[0057] A spring 36 is arranged between the support plate 35 and the movable plate 32, and two ends of the spring 36 are connected to the support plate 35 and the movable plate 32 respectively. When the spring 36 is not subjected to external force, there is a certain spacing between the movable plate 32 and the pressure measuring tube 33, and after the movable plate 32 is adsorbed by the piston 31 to the pressure measuring tube 33, the spring 36 is in a stretched state.

[0058] Through the design of the spring 36, the movable plate 32 can be automatically reset, so that after the pressure in the tank 10 decreases, the warning assembly 40 automatically stops the sound and light warning.

[0059] Preferably, the movable plate 32 is provided with a guide rod 37, the support plate 35 is provided with a guide hole for the guide rod 37 to slide, a contact switch 41 is arranged on the support plate 35, and a pressing plate 38 is arranged on one end of the guide rod 37 penetrating through the guide hole.

[0060] When the movable plate 32 is adsorbed by the piston 31, the guide rod 37 pulls the pressing plate 38 to move, so as to trigger the warning function of the warning assembly 40 through the contact between the pressing plate 38 and the contact switch 41. The contact switch 41 is designed to be away from the pressure measuring tube 33, so as to avoid the influence of the magnet in the piston 31 on the contact switch 41.

[0061] In addition, the guide rod 37 can also limit the movement path of the movable plate 32.

[0062] In another specific embodiment,

[0063] The pressure measuring tube 33 is a transparent structure, and the pressure measuring tube 33 is made of plastic or tempered glass. By arranging the pressure measuring tube 33 as a transparent structure, the position of the piston 31 can be observed, and in addition, a scale can be arranged on the outer wall of the pressure measuring tube 33, so that the pressure value borne by the cover body 20 can be observed in real time.

[0064] In another specific embodiment,

[0065] The pressure measuring tube 33 is arc-shaped and arranged on the cover body 20. Since the surface of the cover body 20 is an arc-shaped structure, the arc-shaped pressure measuring tube 33 is beneficial to arrangement and can be better installed on the cover body 20.

[0066] The above-described embodiments only express the specific implementation of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
