Description

Technical Field

[0001] This utility model relates to the field of waterproofing technology, specifically a rainproof and moisture-proof device for equipment wells in sewage treatment plants. Background Technology

[0002] Equipment management is a core aspect of wastewater treatment plant operation and maintenance. The plant area typically contains numerous valve wells and equipment wells, most of which are located outdoors. For ease of maintenance and cost control, these well openings are often covered with grating covers. However, during the rainy season, the equipment inside these wells is highly susceptible to immersion in rainwater or prolonged exposure to a damp environment, significantly shortening their lifespan. Currently, three main rain protection measures are commonly used inside the wells: 1. Constructing rainwater pipes for gravity drainage into the rainwater system: This method requires the bottom of the equipment well to be higher than the rainwater system interface elevation, which is often difficult to meet on-site. 2. Installing a drainage pump inside the well: Fixed installation of a pump inside the well requires additional space and power lines. More importantly, pumps are prone to malfunction if left idle for extended periods, making it impossible to activate them promptly when needed. 3. Using only a pump pit and a temporary pump to drain accumulated water: This method relies on the water reaching a certain depth before the temporary pump can be activated, failing to remove small amounts of water in time, resulting in a persistently damp environment inside the well and accelerating corrosion and damage to equipment and valves. Utility Model Content

[0003] In view of the shortcomings of the prior art, the present invention provides a rainproof and moisture-proof device for equipment wells in sewage treatment plants, so as to solve the problem of inconvenient cleaning of equipment wells due to water ingress in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rainproof and moisture-proof device for equipment wells in sewage treatment plants, comprising a fixed frame, several guide rods, a support frame, a top cover, and a limiting component. The fixed frame is horizontally fitted onto the top of the equipment well, and the fixed frame and the top plane of the equipment well are in sealed contact. The guide rods are vertically arranged inside the equipment well and evenly distributed. Several sliding sleeves are fixedly connected inside the fixed frame, and the guide rods and sliding sleeves are slidably engaged. The support frame is located above the equipment well, and the top ends of the guide rods are fixedly connected to the support frame. The top cover is fixedly installed on the top of the support frame. A baffle is arranged around the top surface of the fixed frame, and the bottom surface of the top cover is in contact with the top surface of the baffle. An openable door is provided on the top cover. A drying chamber for storing desiccant is fixedly installed below the top cover. The limiting component is used for axial positioning of the guide rods. The working principle of this utility model is as follows: the top cover blocks rainwater, the guide rod ensures the top cover rises and falls vertically, and when the top cover falls, it forms a dynamic seal by pressing the sealing ring and the baffle together. The fixed frame blocks the infiltration of surface water, the drying chamber absorbs moisture in the well, the limiting component locks the structural position, and the desiccant can be quickly replaced through the hatch, so as to achieve all-weather sealing and moisture prevention of the equipment well.

[0005] Preferably, the top cover has a notch, and a movable cover of a suitable size is provided in the notch. One side of the movable cover is hinged to the inner side of the notch. A first sealing strip is provided on the contact surface between the movable cover and the top cover. A second sealing strip is provided on the top surface of the baffle.

[0006] Preferably, a moisture-proof cloth is fixedly installed on the inner wall of the equipment well.

[0007] Preferably, the top cover includes two inclined plates and two side plates, with the upper edges of the two inclined plates fixedly connected. The side plates are isosceles triangular structures and are vertically fixed at the ends of the two inclined plates.

[0008] Preferably, a movable cover is provided on the side of each of the two inclined plates that are separated, and the drying chamber is fixedly installed on the bottom surface of the movable cover.

[0009] Preferably, the limiting assembly includes two push plates and four limiting rods. The four limiting rods are parallel and symmetrically arranged. The limiting rods slide through the interior of the fixed frame, with one end extending to the exterior of the fixed frame and the other end extending into the interior of the sliding sleeve. The guide rod has annular grooves at both ends, and the ends of the limiting rods are adapted to the annular grooves. The two push plates are vertically arranged on both sides of the fixed frame, and the ends of the limiting rods extending to the exterior of the fixed frame are fixedly connected to the push plates.

[0010] Preferably, a limit block is fixedly provided at the bottom of the guide rod.

[0011] Preferably, the lower edges of the movable cover and the inclined plate are respectively fixedly provided with grips.

[0012] Preferably, a sealing ring is fitted onto the limiting rod.

[0013] Preferably, the top cover is provided with a viewing window, and the desiccant is blue color-changing silica gel.

[0014] Compared with existing technologies, the technical solution of this application has the following technical advantages: the fixed frame is in sealed contact with the ground and adapts to the wellhead, blocking rainwater infiltration and solving the problem of poor sealing of the grid cover, and is not dependent on the elevation of the equipment well and the rainwater system. The top cover and the baffle form a waterproof barrier through the sealing ring, which, together with the drying chamber below, actively absorbs moisture, avoiding the lag in pumping out water after the temporary pump accumulates water, and eliminating the need to occupy space inside the well to install a fixed water pump and wiring, reducing the risk of failure. The guide rod and the sliding sleeve slide together, and the limiting component positions, ensuring stable lifting and lowering of the top cover. When changing the desiccant, only the door needs to be opened, which is highly convenient. The drying chamber allows for desiccant replacement, continuously maintaining a dry environment, delaying equipment corrosion, and extending service life. In summary, this device is designed through a combination of passive sealing, active dehumidification, and convenient maintenance. Attached Figure Description

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] like Figure 1As shown, a rainproof and moisture-proof device for equipment wells in sewage treatment plants includes a fixed frame 9, several guide rods 2, a support frame 15, a top cover 16, and a limiting assembly. The equipment well 1 can be a maintenance well for various types of equipment 3 or valves, and its size is not limited. The projection of the fixed frame 9 on the horizontal plane can cover the equipment well 1. The fixed frame 9 is horizontally set on the top of the equipment well 1, and the fixed frame 9 and the top plane of the equipment well 1 are in sealed contact. The top plane of the equipment well 1 is generally a hardened ground. The fixed frame 9 is connected to the ground by expansion bolts and sealing strips to prevent rainwater from entering the equipment well 1 through the gap between the fixed frame 9 and the hardened ground. The guide rods 2 are vertically set inside the equipment well 1 and evenly distributed. Several sliding sleeves 8 are fixedly connected inside the fixed frame 9. Connecting rods can be set between the outer wall of the sliding sleeves 8 and the fixed frame 9 to weld them into a stable and reliable structure. In this embodiment, the top of the equipment well 1 is rectangular, and the guide rods are fixedly arranged at the four corners of the rectangle. The guide rod 2 and the sliding sleeve 8 are slidably engaged, with a gap between them to facilitate sliding. The support frame 15 is located above the equipment well 1. The top end of the guide rod 2 is fixedly connected to the support frame 15. The top cover 16 is fixedly mounted on the top of the support frame 15. The projection of the top cover 16 on the water surface is larger than that of the fixed frame 9, preventing rainwater from falling directly onto the fixed frame 9. A baffle 5 is arranged around the top surface of the fixed frame 9, and the bottom surface of the top cover 16 is in contact with the top surface of the baffle 5. The baffle 5 forms a rectangular ring and is fixedly mounted on the fixed frame 9. Under the action of gravity, the top cover 16 and the baffle 5 are in sealed contact, preventing moisture or rainwater from entering. A desiccant storage chamber 7 is fixedly mounted below the top cover 16, allowing workers to quickly replace the desiccant. An openable hatch is provided on the top cover 16. The limiting component is used for axial positioning of the guide rod 2. When maintenance is required on equipment 3, the operator lifts the top cover 16 and uses the limiting component to limit the bottom of the guide rod 2, preventing it from sliding downwards. The operator can then enter the equipment well 1 to perform the work. Equipment 3 is located inside the equipment well and maintains a safe distance from the guide rod 2.

[0023] like Figure 1 , 2As shown, preferably, the top cover 16 has a notch, and a movable cover 12 of suitable size is disposed within the notch. One side of the movable cover 12 is hinged to the inner side of the notch, and a first sealing strip 19 is provided on the contact surface between the movable cover 12 and the top cover 16. A second sealing strip 6 is provided on the top surface of the baffle 5. When opened, the movable cover 12 is pushed to rotate around the hinge side to open the notch. When closed, the movable cover 12 and the notch of the top cover 16 are fitted together and the contact surface is sealed by the first sealing strip 19. At the same time, the second sealing strip 6 on the top surface of the baffle 5 is fitted to the bottom surface of the top cover 16 to achieve a rainproof seal. In this embodiment, a groove is provided on the side wall of the notch, with the groove opening facing the side of the movable cover 12, and the second sealing strip 6 is disposed in the groove. The second sealing strip 6 protrudes from the side wall of the channel opening.

[0024] Preferably, a moisture-proof cloth 14 is fixedly installed on the inner wall of the equipment well 1. The moisture-proof cloth 14 is made of polyethylene, and its size is customized according to the dimensions of the equipment well 1. Holes are pre-drilled on each covering surface of the moisture-proof cloth 14, and the holes can be used to hang it on the hooks set at the top of the equipment well for fixation. The moisture-proof cloth 14 can be replaced at any time if its performance deteriorates or it is damaged.

[0025] like Figure 3 As shown, preferably, the top cover 16 includes two inclined plates 4 and two side plates 13. The upper edges of the two inclined plates 4 are fixedly connected, and the side plates 13 are isosceles triangular structures, vertically fixed at the ends of the two inclined plates 4. The top cover 16 structure guides rainwater to slide down quickly through the inclined plates 4, and the closed design of the vertical ends of the isosceles triangular side plates 13 effectively reduces water accumulation and enhances structural rigidity.

[0026] like Figure 2 As shown, preferably, each of the two inclined plates 4 has a movable cover 12 on its opposite side, and the drying chamber 7 is fixedly mounted on the bottom surface of the movable cover 12. When the movable cover 12 is opened, it facilitates quick opening for maintenance or replacement of the desiccant. Simultaneously, the movable cover 12 seamlessly connects with the inclined plate 4 of the top cover 16, ensuring that the drying chamber 7 is tightly attached to the bottom of the top cover 16, improving moisture absorption efficiency and enhancing the overall moisture-proof effect. In this embodiment, an L-shaped support net is fixedly mounted at the bottom of the movable cover 12, forming a semi-open drying chamber 7. Desiccant is placed on the support net. Workers can remove and place the desiccant from the side of the support net.

[0027] like Figure 1As shown, preferably, the limiting assembly includes two push plates 11 and four limiting rods 10. The four limiting rods 10 are parallel and symmetrically arranged. The limiting rods 10 slide through the interior of the fixed frame 9, with one end extending to the outside of the fixed frame 9 and the other end extending into the interior of the sliding sleeve 8. The guide rod 2 has annular grooves 17 at both ends, and the ends of the limiting rods 10 are adapted to the annular grooves 17. The fixed frame 9 has a first through hole adapted to the limiting rods 10, and the sliding sleeve 8 has a second through hole for the limiting rods 10 to enter. The axis of the limiting rods 10 intersects the axis of the sliding sleeve 8. The two push plates 11 are vertically arranged on both sides of the fixed frame 9, and the ends of the limiting rods 10 extending to the outside of the fixed frame 9 are fixedly connected to the push plates 11. By linking the push plate 11 with the four symmetrical limiting rods 10 and engaging with the annular groove 17 on the guide rod 2, the guide rod 2 can be quickly axially positioned. This method is convenient to operate and securely fixed, effectively preventing the guide rod 2 from sliding and improving the structural stability of the device.

[0028] like Figure 1 As shown, preferably, a limit block 18 is fixedly provided at the bottom of the guide rod 2 to prevent the guide rod 2 from disengaging from the sliding sleeve 8 when it moves upward.

[0029] Preferably, the lower edges of the movable cover 12 and the inclined plate 4 are respectively provided with handles. This facilitates the comfort of the staff when moving the movable cover 12 or the inclined plate 4.

[0030] Preferably, a sealing ring is fitted on the limiting rod 10 to prevent rainwater from entering the equipment well 1 along the limiting rod 10.

[0031] Preferably, the top cover 16 is provided with a viewing window, and the desiccant is blue color-changing silica gel. By combining the viewing window of the top cover 16 with the blue color-changing silica gel desiccant, the moisture-absorbing and color-changing properties of silica gel are utilized to achieve intuitive and visual monitoring of the drying status.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
