Description

Technical Field

[0001] This utility model relates to the field of environmental protection, specifically to a wastewater treatment equipment. Background Technology

[0002] Underground wastewater treatment plants / areas offer advantages such as low noise, no odor, and small footprint, making them a preferred construction option for new plants in urban centers. A key feature of underground wastewater treatment plants / areas is that all water treatment units are located underground, while other supporting equipment and devices are arranged within the water treatment units or above ground according to a plan.

[0003] A gate valve is a device used to control the flow of water between water treatment units, such as between screen tanks. The working part (valve body) of the gate valve is installed between water treatment units below ground level, while its control part (handwheel or electrically controlled drive mechanism) is located above ground, with a through-hole in the ground for the gate valve to pass through. This installation method presents two problems:

[0004] Question 1: Because the gate valve's working part needs to be switched on and off, the corresponding through holes on the ground cannot be sealed, which poses a safety risk of people or objects falling or accidentally entering.

[0005] Question 2: There is no protection around the gate valve, which poses a safety hazard. Utility Model Content

[0006] To solve the above technical problems, this utility model provides a system that provides protection around a gate valve installed in the area above and below ground. The main technical solution adopted is as follows:

[0007] A protective system for inlet and outlet gate valves in an underground sewage treatment plant includes a floor beneath which lies the sewage treatment area. Gate valve installation ports are provided on the floor. The key feature is:

[0008] A base is fixed to the upper surface of the floor, which is close to the mounting port of the gate valve. A protective box is connected to the base. The protective box has openings at both the top and bottom. The protective box is arranged around the working part of the gate valve. The lower edge of the protective box contacts the floor, and the lower opening of the protective box surrounds the mounting port of the gate valve.

[0009] The above technical solution provides good stability after the protective box is connected to the base, which can prevent it from colliding with the gate valve and provide a protective enclosure for the gate valve; while the lower edge of the protective box contacts the floor to prevent objects from falling. Attached Figure Description

[0010] Figure 1 This is a schematic diagram showing the assembly relationship between base 3 and floor 1;

[0011] Figure 2 This is a schematic diagram of the structure of protective box 4;

[0012] Figure 3 This is a schematic diagram showing the assembly relationship between the base 3 and the protective box 4. Detailed Implementation

[0013] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0014] like Figure 1 , Figure 2 and Figure 3 As shown, a protective system for inlet and outlet gate valves in an underground sewage treatment plant includes a floor 1, beneath which lies the sewage treatment area. A gate valve mounting port 1a, a rectangular opening, is provided on the floor 1 for installing a gate valve. After installation, the working part of the gate valve extends below the floor 1, while the control part is located above it. The control rod of the gate valve vertically passes through the gate valve mounting port 1a.

[0015] A base 3 is fixed to the upper surface of the floor 1, and the base 3 is close to the gate valve mounting port 1a. A protective box 4 is connected to the base 3. The protective box 4 has openings at both the top and bottom. The protective box 4 is arranged around the working part of the gate valve mounting port 1a, and the lower edge of the protective box 4 contacts the floor 1. The lower opening of the protective box 4 surrounds the gate valve mounting port 1a. Preferably, the base 3 and the protective box 4 are detachably connected to avoid interference from the protective box 4 when the gate valve needs maintenance or repair.

[0016] To facilitate the assembly and disassembly of the protective box 4, the protective box 4 is also detachable. A specific assembly and disassembly structure for the protective box 4 is as follows: the protective box 4 includes a box body 41 and a box panel 42. One side of the box body 41 is open to form an assembly / disassembly port. The box panel 42 is vertically positioned and covers the assembly / disassembly port. One vertical side of the box panel 42 is hinged to the box body 41, and the other vertical side of the box panel 42 is detachably connected to the box body 41. One method of detachable connection between the box panel 42 and the box body 41 is a latch lock detachable connection. With this structure, the protective box 4 can be assembled and disassembled from the side of the gate valve, offering advantages of convenience and speed.

[0017] A detachable connection structure for a base 3 and a protective box 4 is as follows: the base 3 includes two horizontally arranged slide rails 31, which are parallel to each other. Each slide rail 31 is provided with a horizontal groove 3a, which is arranged along the length of the slide rail 31. Both ends of the horizontal groove 3a are open, and the opening of the horizontal groove 3a is preferably not facing upwards. Furthermore, the opening of the horizontal groove 3a is located on the side surface of the slide rail 31.

[0018] Two anti-detachment clips 43 are horizontally fixed at the bottom of the housing 41. The two anti-detachment clips 43 are parallel to each other, and one end of the anti-detachment clip 43 points to the disassembly port. The two anti-detachment clips 43 correspond one-to-one with the two slide rails 31. The anti-detachment clip 43 is inserted into the horizontal slide groove 3a from either end of the slide rail 31.

[0019] The anti-detachment clip 43 and the horizontal slide groove 3a cooperate with each other to limit the vertical movement of the base 3 and the protective box 4 in both directions (restricting their relative movement or limiting their relative movement to a very small range, the same below), and also limit the vertical movement of the base 3 and the protective box 4 in both directions in the horizontal direction perpendicular to the slide rail 31.

[0020] After both vertical sides of the box panel 42 are connected to the box body 41, one end of the slide rail 31 approaches or contacts the inner wall of the box panel 42, and the other end of the slide rail 31 approaches or contacts the inner wall of the box body 41. This provides bidirectional positioning of the base 3 and the protective box 4 in the horizontal direction parallel to the slide rail 31.

[0021] One specific structure of the slide rail 31 is as follows: the slide rail 31 includes a floor connecting strip, a vertical support strip, and an inverted strip. The floor connecting strip and the inverted strip are arranged horizontally, and the vertical support strip is arranged vertically. The floor connecting strip and the inverted strip are located on both sides of the vertical support strip. One side of the floor connecting strip is fixedly connected to the lower edge of the vertical support strip, and one side of the inverted strip is fixedly connected to the upper edge of the vertical support strip. The floor connecting strip is fixedly connected to the floor 1, and the horizontal groove (3a) is formed between the inverted strip and the floor 1. The connecting strips of the two slide rails 31 are close to each other, and the inverted strips of the two slide rails 31 are far apart from each other.

[0022] The protective box 4 is provided with a transparent observation area 4a, which is preferably a transparent acrylic plate embedded in the protective box 4.

[0023] Warning signs 4b are also affixed to the outer wall of the protective box 4.

[0024] To enhance the strength of the protective box 4, the protective box 4 includes an inner support frame and a skin attached to the outside of the inner support frame. The inner support frame is preferably made of angle steel and steel bars, and the skin is preferably made of sheet metal. The slide rail 31 and the anti-detachment clip 43 are both located inside the protective box 4.

[0025] Beneficial effects: The technical solution of this utility model can protect the gate valve installed through the floor, preventing personnel and objects from colliding with the gate valve; at the same time, the protective box can be quickly disassembled and installed, preventing it from affecting the maintenance of the gate valve.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
