Technical Field
[0001] This utility model relates to the field of operating well technology, and in particular to a protective cover for an operating well and an operating well. Background Technology
[0002] Gas station load-bearing tanks are typically located in the forecourt work area. Gas station staff need to open the load-bearing tank access well to regularly inspect and maintain its contents. When inspecting or cleaning the well, staff usually do so from the edge of the access well opening, minimizing the need for employees to enter the confined space and improving safety. However, this poses a safety risk as staff may fall into the well. Furthermore, standing on the edge of the access well opening is not conducive to proper work.
[0003] CN201620845158.3 discloses a manhole access well with a sub-cover, including a main body and a horizontally closed sub-cover inside the main body. The sub-cover is openable and located inside the main body. Using this solution, the present invention provides a manhole access well with a cover that avoids contamination of the working conditions inside the well by debris. However, when workers need to inspect the inside of the access well, they can only enter the well or work at the edge of the access well. The limited space inside the well is not conducive to work, and there is a risk of falling at the edge of the access well, resulting in low safety.
[0004] The technical problem this invention aims to solve is: how to reduce the number of times workers need to enter the operating well, and improve the convenience and safety of inspecting the condition inside the operating well. Utility Model Content
[0005] The main objective of this invention is to provide a protective cover for an operating well. By installing a protective cover at the opening of the operating well, workers can stand on the cover and inspect the inside of the well through the operating hole, preventing workers from falling into the operating well and improving safety. An operating well is also provided.
[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0007] A protective cover for an operating well includes a cover body; the cover body has an operating hole; the cover body has a dividing member for dividing the operating hole into at least two sub-operating holes or a covering member for changing the area of the operating hole; the area of the sub-operating holes is smaller than the area of the operating hole.
[0008] Preferably, there are multiple operating holes; the multiple operating holes are divided into first operating holes and second operating holes; the dividing member or covering member acts on the first operating hole; the area of the first operating hole is larger than the area of the second operating hole.
[0009] Preferably, the area of the first operating hole is 600 cm². 2 ~650cm 2 The area of the second operating hole is 160 cm². 2 ~210cm 2 .
[0010] In some embodiments of this solution, the area of the first operating hole is 600 cm². 2 610cm 2 620cm 2 630cm 2 640cm 2 650cm 2 The area of the second operating hole is 160 cm². 2 170cm 2 180cm 2 190cm 2 200cm 2 210cm 2 .
[0011] Preferably, the cover is provided with a plurality of fixing holes arranged in a circumferential array; the dividing member or covering member is provided with limiting holes; the limiting holes cooperate with the fixing holes to prevent the dividing member or covering member from rotating on the cover.
[0012] Preferably, the thickness of the cover is 6mm to 10mm; both the cover and the cross plate are made of aluminum alloy.
[0013] In some embodiments of this solution, the thickness of the cover is 6mm, 7mm, 8mm, 9mm, or 10mm.

[0016] Compared with existing technologies, this solution has the following advantages:
[0017] In this case, the protective cover allows workers to easily inspect the well by simply placing it at the well opening. Workers can stand on the cover while the inspection equipment passes through the opening to check the inside of the well. This prevents workers from falling while operating at the well's edge. Furthermore, the protective cover provides ample space for operation. After the inspection is complete, rotating the horizontal plate changes the operable area of the opening, further preventing workers' feet from getting stuck in the well and improving safety.
[0018] Secondly, the protective cover can be placed inside the operating well, and then the well cover can be placed at the well opening, thus avoiding the need to remove and put the protective cover in for each inspection, improving the convenience of operation. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0024] Example 1
[0025] refer to Figure 1-2 A protective cover for operating wells includes a cover body 1; the cover body 1 is provided with an operating hole 2; the cover body 1 is provided with a dividing member 4 for dividing the operating hole 2 into at least two sub-operating holes 3; the area of the sub-operating holes 3 is smaller than the area of the operating hole 2.
[0026] In this embodiment, the shape of the protective cover matches the shape of the operating well opening. When the operating well needs to be inspected, the well cover 7 is removed, and then the protective cover is placed at the operating well opening. Workers can stand on the protective cover and inspect the inside of the well through the operating hole 2. Workers can insert inspection tools through the operating hole 2 to inspect the inside of the well. Workers can rotate the dividing piece 4 to divide the operable space of the operating hole 2, so that the operating hole 2 can be used as a single unit or divided into two sub-operating holes 3 to accommodate different inspection tools and prevent workers' feet from falling out of the operating hole 2, thus improving safety.
[0027] By standing on the protective cover to perform the work, the operating space for the staff is increased, and the number of times the staff need to enter the operating well can be reduced, thereby improving safety and ease of operation.
[0028] Preferably, there are multiple operating holes 2; the multiple operating holes 2 are divided into a first operating hole 21 and a second operating hole 22; the dividing member 4 acts on the first operating hole 21; the area of the first operating hole 21 is larger than the area of the second operating hole 22.
[0029] In this embodiment, the protective cover is provided with multiple first operating holes 21 and second operating holes 22. The dividing member 4 rotates on the protective cover, thereby dividing the operable area of the first operating hole 21 into two sub-operating holes 3. When the second operating hole 22 cannot accommodate the passage of an inspection tool, the dividing member 4 is rotated, changing the operable area of the first operating hole 21 so that a larger inspection tool can pass through. When the first operating hole 21 is not needed, the dividing member 4 is rotated onto the first operating hole 21, thereby dividing the first operating hole 21 into two parts and preventing the worker's foot from getting stuck in the first operating hole 21. By providing multiple first operating holes 21 and second operating holes 22, multiple workers or multiple inspection tools can work simultaneously, improving efficiency.
[0030] Preferably, the area of the first operating hole 21 is 600 cm². 2 ~650cm 2 The area of the second operating hole 22 is 160 cm². 2 ~210cm 2 .
[0031] In this embodiment, the area of an adult's foot is approximately 210 cm². 2 The area of the first operating hole 21 is preferably 610 cm². 2 The first operating hole 21 is divided by the dividing piece 4, and the first operating hole 21 can be divided into approximately 200cm sections. 2 The two parts prevent workers' feet from getting stuck in the first operating hole 21, improving operational safety. The area of the second operating hole 22 is preferably 200 cm². 2 When staff are wearing shoes, their feet will not get stuck in the second operating hole 22.
[0032] Preferably, the cover 1 is provided with a plurality of fixing holes 11 arranged in a circumferential array; the dividing member 4 is provided with a limiting hole 41; the limiting hole 41 cooperates with the fixing hole 11 to prevent the dividing member 4 from rotating on the cover 1.
[0033] In this embodiment, when the dividing member 4 needs to be rotated into or away from the operating hole 2, a pin or other fastener is required to pass through the limiting hole 41 and the fixing hole 11 to prevent the dividing member 4 from rotating due to error, which would affect the operator's work and safety.
[0034] Preferably, the thickness of the cover 1 is 6mm to 10mm; both the cover 1 and the partition plate are made of aluminum alloy.
[0035] In this embodiment, the thickness of the cover 1 is preferably 6mm, which can support the weight of a person. Since gas stations require anti-static properties, the protective cover is made of aluminum alloy to prevent the generation of static electricity and avoid spark explosions.
[0036] Preferably, the cover 1 is provided with a handle 12.
[0037] In this embodiment, the handle 12 is connected to the cover 1 by means of threads or snap-fit. When workers need to enter the well for further inspection, they can lift the protective cover using the handle 12 and move it outside the well opening.
[0038] Example 2
[0039] refer to Figure 3 This embodiment is basically the same as Embodiment 1, except that: the cover 1 is provided with a covering 5 for changing the area of the operating hole 2. The covering 5 is rotatably connected to the cover 1. When it is necessary to increase the operable area of the operating hole 2, the covering 5 is rotated to reduce the area covered by the covering 5 of the operating hole 2, thereby increasing the operable area of the operating hole 2, so that the inspection tool can pass through the operating hole 2 to inspect the operating well.
[0040] Example 3
[0041] refer to Figure 4 An operating well includes an operating well body 6 and a well cover 7; it also includes a protective cover as described above; the operating well body 6 is provided with a groove 61; the well cover 7 and the protective cover are connected from top to bottom in the groove 61.
[0042] In this embodiment, the operating well is the operating well for the load-bearing tank of a gas station. The protective cover and the well cover 7 can be placed together inside the well opening. After the staff has checked that the condition inside the well is normal, they only need to put the well cover 7 on. There is no need to move the protective cover back and forth for each inspection, which reduces the workload of the staff.
[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
