Specific embodiments

[0024] The present utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0025] Embodiment 1:

[0026] The automatic switch device of this example includes a mounting plate 1 fixedly installed on the pump house box body. The mounting plate 1 is correspondingly fixed on the inspection opening of the pump house box body, and the automatic switch mechanism is all installed on the mounting plate 1. Through the independent processing and installation of this device, a modular design is realized.

[0027] An edge plate 2 is provided at the edge of the mounting plate 1, and mounting holes are provided on the edge plate 2, and it is fixedly installed on the box body inspection opening through bolt assemblies.

[0028] A cover opening 3 penetrating the mounting plate 1 up and down is provided on the mounting plate 1, and a cover plate 4 that can be hermetically closed with it is fitted on the cover opening 3, and the shapes of the cover opening 3 and the cover plate 4 correspond to each other.

[0029] In this example, as Figure 1 shown, the schematic cover plate 4 is circular. Without being limited to this example, a rectangular cover plate 4 and cover opening 3 can also be used.

[0030] One side of the cover plate 4 is provided with a rectangular bump 5, and one side of the cover opening 3 is provided with a notch corresponding to the bump 5. The notch creates space to make way for the strokes of the upper pull rod and the lower pull rod during the lifting action of the cover plate 4, and enables the cover plate 4 to be located above the notch on one side of the cover opening 3 after being lifted, without blocking the maintenance space of the cover opening 3.

[0031] The top surface of the cover plate 4 is hinged with an upper connecting rod 6. One end of the upper connecting rod 6 far from the cover plate 4 is hinged to the mounting plate 1. For the sake of stable movement and good load-bearing capacity, two upper connecting rods 6 are provided. The two upper connecting rods 6 are symmetrically arranged relative to the cover plate 4, and in the case where the bump 5 is provided, the two upper connecting rods 6 are symmetrically arranged left and right relative to the bump 5. The hinged position of the upper connecting rod 6 and the cover plate 4 is arranged near the side of the bump 5. The upper connecting rod 6 has an upward-arching 90-degree bend 7 near the cover plate 4 to make way for the lifting of the cover plate 4.

[0032] The bottom surface of the cover plate 4 is hinged with a lower connecting rod 8. For the sake of stable movement and good load-bearing capacity, two lower connecting rods 8 are arranged in parallel. The top ends of the lower connecting rods 8 are hinged to the bottom surface of the cover plate 4.

[0033] On the bottom surface of the mounting plate 1, a first hinge seat 9 and a second hinge seat 10 are provided. The first hinge seat 9 has two and is symmetrically arranged on both sides of the notch. The bottom ends of the lower connecting rods 8 are hinged to the first hinge seat 9. A cylinder body 11 is rotatably installed on the second hinge seat 10. The cylinder body 11 adopts a common cylinder body 11 structure such as an electric push rod, a hydraulic rod, or a cylinder. One end of the cylinder body 11 close to the cover opening 3 is provided with a cylinder rod 12 that is telescopically matched with it. One end of the cylinder rod 12 close to the cover opening 3 is provided with a connecting pin 13 that vertically penetrates it and extends horizontally. The connecting pin 13 is rotatably connected to the cylinder rod 12. Driving rods 14 are respectively fixed at both ends of the connecting pin 13. The top ends of the driving rods 14 are integrally fixed and connected to the bottom ends of the lower connecting rods 8. An obtuse angle is formed between the lower connecting rod 8 and the driving rod 14. When the cylinder rod 12 extends, it pushes the connecting pin 13 towards the cover opening 3. Under the constraint of the hinge between the lower connecting rod 8 and the first hinge seat 9, the driving rod 14 swings to drive the lower connecting rod 8 to swing, so that the cover plate 4 is opened upwards, and at the same time, with the cooperation of the hinge of the upper connecting rod 6 on one side of the bump 5, the opened cover plate 4 is lifted to form a state where the bump 5 is on top and the cover plate 4 is inclined above the notch, as Figure 1 shown.

[0034] Under the above structure, the automatic driving and control of the opening action of the cover plate 4 are realized, which is labor-saving and efficient. Non-manual operation is safer. The opening process fully considers the space limitation, and the effect of the cover plate 4 being obliquely erected on one side after being opened upwards is realized, so as to facilitate the staff to enter and exit up and down at the cover opening 3 and leave sufficient space for maintenance operations.

[0035] Embodiment 2:

[0036] On the basis of Embodiment 1, this example takes into account the need for personnel to enter the pump room. If it is for simple maintenance or for maintaining equipment in the upper part of the pump room, such as checking monitoring equipment, routing wires, etc., there is no need to go down to the bottom of the pump room. However, it is very unsafe for personnel to reach into the pump room, and it is very difficult to operate in terms of actions.

[0037] On the top surface of the cover plate 4, there are two parallel convex strips 15. The convex strips 15 are symmetrically arranged on both sides of the convex block 5. On the inner sides of the opposite convex strips 15, there are strip-shaped grooves 16. One end of the strip-shaped groove 16 away from the convex strip 15 is a closed end. There is a strip-shaped frame 17 between the two convex strips 15. The length direction of the strip-shaped frame 17 is the same as that of the convex strip 15. On both sides of the strip-shaped frame 17, there are symmetrically arranged sliders that are slidably matched with the strip-shaped grooves 16. The sliders cannot pass through the closed end. The sliders are arranged at one end of the strip-shaped frame 17 close to the convex block 5. At the other end of the strip-shaped frame 17 away from the sliders, there is a pedal 18.

[0038] One end of the strip-shaped frame 17 close to the convex block 5 is penetrated by a pin rod that is movably inserted therein. One end of the convex strip 15 close to the convex block 5 is provided with a pin hole that is movably inserted with the pin rod. When the pin rod penetrates the strip-shaped frame 17 and the pin hole, it can simply limit the strip-shaped frame 17 and the cover plate 4, so that the strip-shaped frame 17 is usually stored as a spare on the cover plate 4. Even when the cover plate 4 is lifted, the strip-shaped frame 17 will not move under the limit of the pin rod. When the pin rod is taken out, when the cover plate 4 is lifted, the strip-shaped frame 17 will fall, and the slider is blocked by the closed end at the bottom of the strip-shaped groove 16, thereby obtaining a pedal 18 structure for reaching into the upper part of the pump room, which is convenient for personnel to rely on the support of the pedal 18 to maintain the upper part of the pump room.

[0039] Embodiment 3:

[0040] On the basis of Embodiment 1, this example takes into account the need for personnel to enter the pump room. The facilities at the bottom of the pump room are complex, it is difficult to place a ladder on the top to enter the pump room, and it is very dangerous without a ladder for people to climb. Therefore, two parallel convex strips 15 are provided on the top surface of the cover plate 4. The convex strips 15 are arranged on the side away from the convex block 5. Therefore, when the cover plate 4 is tilted, the convex strips 15 are located at the bottom of its top surface. There is a slot 19 on the convex strip 15. One end of the slot 19 away from the convex strip 15 is a closed end.

[0041] It further includes an independently configured bar-shaped frame 17. The width of the bar-shaped frame 17 is adapted to the spacing between the two convex strips 15. On both sides of the top end of the bar-shaped frame 17, there are support blocks 20 protruding towards both sides. The support blocks 20 are movably inserted into the slot 19. After the support blocks 20 are inserted into the slot 19, they are supported by the closed end, so that the top end of the bar-shaped frame 17 is hung between the two convex strips 15. A plurality of pedals 18 are provided on the bar-shaped frame 17. After the cover plate 4 is started, the convex block 5 of the cover plate 4 stands obliquely upward on one side of the cover opening 3. By inserting the support block 20 of the bar-shaped frame 17 into the slot 19, a ladder structure hanging on the cover plate 4 can be obtained. This ladder structure sinks into the pump room, facilitating personnel to enter the pump room for operation.

[0042] Multiple examples are all improved designs, and their advantages include:

[0043] In the above-mentioned embodiments, a modular design is adopted, automating the opening and closing structure and modularly installing it on the pump room box body, which is convenient for processing and production and realizes a series of products with multiple models.

[0044] The operation of automatic opening and closing replaces manual opening and closing. The seal is firm and easy to open. The operation is labor-saving and efficient, and there will be no problem of being difficult to open after being placed for a long time.

[0045] After being opened, the cover plate 4 stands obliquely on one side of the cover opening 3, thus making way for the cover opening 3 and the space above it, facilitating personnel to enter and exit for operation and maintenance.
