Description

Technical Field

[0001] This application relates to the technical field of valve well protection, and in particular to a practical valve well protective cover. Background Technology

[0002] Valve wells, as an important component of underground pipeline systems, are widely used in municipal, industrial, energy, and agricultural fields. Their core function is to house and control various pipeline valves, facilitating routine maintenance, repairs, and rapid response in emergencies. In actual operation, valves in valve wells are typically exposed above ground, directly exposed to external environmental corrosion; therefore, protective covers are required to protect them.

[0003] In related technologies, the protective cover for valve wells is typically a hollow, cubic shell placed on the ground around the valve well, enclosing the valve and providing protection. When it is necessary to operate the valve inside the valve well, the protective cover needs to be moved. Due to its considerable weight, it requires two people to lift it, which is labor-intensive and poses a safety hazard of bumps and knocks. Utility Model Content

[0004] In order to greatly save manpower and improve safety when valves need to be operated, this application provides a practical valve well protective cover.

[0005] Firstly, this application provides a practical valve well protective cover, which adopts the following technical solution:

[0006] A practical valve well protective cover includes a housing covering the valve well. The housing has an operating port for convenient operation of the valve well inside the housing. Water-blocking strips are fixed around the perimeter of the operating port and extend away from the housing. A cover plate that can completely cover the operating port is movably installed on the housing. The cover plate abuts against the water-blocking strips. An installation mechanism is also provided between the housing and the cover plate to reduce the deviation of the cover plate from the operating port.

[0007] By adopting the above technical solution, by opening an operating port on the shell and installing a cover plate at the operating port, the water-blocking strip helps to reduce the inflow of rainwater from the operating port. When it is necessary to operate the valve in the valve well, simply lift the cover plate to expose the operating port without lifting the shell. It is simple and practical, greatly reduces manpower and improves safety.

[0008] Optionally, a sealing ring is also fixed on the water-blocking strip. The sealing ring is located on the side of the water-blocking strip away from the housing, and the cover plate abuts against the sealing ring when it covers the operating port.

[0009] By adopting the above technical solution, the sealing ring further increases the sealing performance between the cover plate and the operating port, reducing the impact of the external environment on the valve well inside the shell.

[0010] Optionally, the cover plate has a bend parallel to the water-blocking strip at its four edges, and the bend is located outside the water-blocking strip. A handle is also fixed in the middle of the cover plate, and the handle is located on the side of the cover plate away from the bend.

[0011] By adopting the above technical solution, the handle makes it easier to lift the cover plate. When the cover plate is placed on the operating opening, the bent part is located outside the water-blocking strip, which further increases the sealing effect of the operating opening and reduces the entry of rainwater.

[0012] Optionally, there may be multiple installation mechanisms, which are spaced apart on the four sides of the cover plate.

[0013] By adopting the above technical solution, the installation mechanism further increases the stability of the connection between the cover plate and the housing, reduces the possibility of the cover plate being detached from the operating port due to external environmental influences, and ensures that the cover plate plays its normal protective role.

[0014] Optionally, the installation mechanism includes a plug rod, a through hole is provided on the bent portion, a slot is provided on the water baffle, the through hole and the slot are aligned when the cover plate is placed on the operating port, and the plug rod passes through the through hole and is inserted into the slot.

[0015] By adopting the above technical solution, when the insertion rod is inserted into the slot and the hole, the cover plate is less likely to detach from the operating port in the vertical direction, which further enhances the stability of the cover plate and the shell.

[0016] Optionally, the mounting mechanism further includes an ejection assembly for easy access to the cover plate, the ejection assembly including a slide bar that pushes the cover plate away from the housing.

[0017] By adopting the above technical solution, the ejector assembly ensures the stability of the cover plate when it is installed on the housing, and also helps to quickly lift the cover plate when operating the valve.

[0018] Optionally, the ejection assembly includes a limiting block fixed to the outside of the bent portion. The limiting block is located on the side of the perforation near the housing. A limiting groove is formed on the limiting block, the length direction of which is parallel to the width direction of the bent portion. A sliding rod is slidably installed in the limiting groove, and both ends of the sliding rod can extend out of the limiting groove. The end of the sliding rod near the handle extends out of the limiting block and is fixed with a baffle. A fixing plate is coaxially fixed to the side wall of the sliding rod away from the baffle. The fixing plate is slidably connected to the inner wall of the limiting groove. Furthermore, a spring is fitted on the outer wall of the slide rod. One end of the spring is fixedly connected to the fixing plate, and the other end is fixed to the inner wall of the limiting groove. An insertion hole is also provided on the side of the slide rod near the baffle. When the end of the slide rod away from the baffle abuts against the housing, the spring is compressed, and the other end of the slide rod extends out of the limiting groove, aligning the insertion hole with the through hole. The insertion rod can simultaneously pass through the insertion hole and the through hole and be inserted into the groove. When the insertion rod is pulled out away from the insertion hole, the spring rebounds, causing the end of the slide rod away from the baffle to push out towards the housing.

[0019] By adopting the above technical solution, when the cover plate needs to be installed and fixed, the cover plate is placed at the operating port, and the lower end of the slide rod is retracted into the limiting groove. At this time, the spring is compressed, causing the upper end of the slide rod to slide upward, and the insertion hole and through hole are aligned. The insertion rod is inserted into the insertion hole, through hole and slot at the same time to enhance stability. When the cover plate needs to be lifted, the insertion rod is pulled out. At this time, the spring rebounds and causes the slide rod to slide towards the housing, giving the cover plate a reaction force, causing the cover plate to be pushed upward, which further facilitates the lifting of the cover plate.

[0020] Optionally, a connecting rope is also fixed to the baffle, and the other end of the connecting rope is fixedly connected to the baffle.

[0021] By adopting the above technical solution, the connecting rope connects the insertion rod to the insertion rod, which helps to reduce the loss of the connecting rope.

[0022] In summary, this application has the following beneficial effects:

[0023] 1. By opening an operating port on the housing and installing a cover plate at the operating port, the water-blocking strip helps to reduce the inflow of rainwater from the operating port. When it is necessary to operate the valve in the valve well, simply lift the cover plate to expose the operating port without lifting the housing. It is simple and practical, greatly reduces manpower and improves safety.

[0024] 2. The installation mechanism further increases the stability of the connection between the cover plate and the housing, reduces the possibility of the cover plate being detached from the operating port due to external environmental influences, and ensures that the cover plate plays its normal protective role.

[0025] 3. The ejector assembly ensures the stability of the cover plate when it is installed on the housing, and also helps to quickly lift the cover plate when operating the valve. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0032] This application discloses a practical valve well protective cover.

[0033] Reference Figure 1 and Figure 2 A practical valve well protective cover includes a housing 1 that covers the outside of the valve well. The housing 1 is placed horizontally on the ground and is a hollow cube. A square operating port 11 is opened on the upper surface of the housing 1, through which the operator can operate the valve. A water-blocking strip 12 is also vertically welded to the upper surface of the housing 1. The water-blocking strip 12 is located at the four edges of the operating port 11 to prevent rainwater from flowing into the operating port 11 along the upper surface of the housing 1. A cover plate 2 is also installed at the operating port 11. The cover plate 2 has the same shape as the operating port 11, and the four edges of the cover plate 2 have bent portions 21. When the cover plate 2 covers the operating port 11, the bent portions 21 are arranged parallel to the outside of the water-blocking strip 12. An installation mechanism 3 is also provided between the cover plate 2 and the housing 1. The installation mechanism 3 ensures the stability of the cover plate 2 when it is placed on the housing 1, and prevents it from being blown away by the wind or deviating from the operating port 11 due to external environmental influences.

[0034] A handle 22 is also fixed to the upper surface of the cover plate 2. The handle 22 is located on the side of the cover plate 2 away from the bend 21, making it easy to lift the cover plate 2. A sealing ring 13 is also fixed to the upper side of the water-blocking strip 12. When the cover plate 2 covers the operating opening 11, the sealing ring 13 abuts against the cover plate 2, further enhancing the sealing performance and reducing the possibility of rainwater entering the operating opening 11.

[0035] There are multiple installation mechanisms 3, and in this embodiment there are four. The four installation mechanisms 3 are located around the operation port 11. Each installation mechanism 3 includes a plug rod 31 and a push-out component 32. A slot 121 is provided on the outer wall of the water baffle 12. A through hole 211 aligned with the slot 121 is provided on the bent part 21. The plug rod 31 passes horizontally through the through hole 211 and is inserted into the slot 121, so that the cover plate 2 is not easy to detach in the vertical direction.

[0036] Reference Figure 3 The ejector assembly 32 includes a limiting block 321 fixed to the outer wall of the cover plate 2. The limiting block 321 is located on the side of the through hole 211 near the housing 1. A limiting groove 3211 with a square cross section is opened on the side of the limiting block 321 away from the cover plate 2. The limiting groove 3211 is opened along the length direction of the limiting block 321 and is connected to the side of the bent part 21 near the housing 1. A sliding hole 3212 is also opened through the side wall of the limiting block 321 near the handle 22. The diameter of the sliding hole 3212 is smaller than that of the limiting groove 3211. The sliding hole 3212 is connected to the limiting groove 3211. A sliding rod 322 is slidably installed in the limiting groove 3211. The length direction of the sliding rod 322 is parallel to the limiting groove 3211, and the length of the sliding rod 322 is longer than that of the limiting groove 3211. The upper end of the slide rod 322 extends out of the limiting groove 3211 through the sliding hole 3212. A baffle 323 is fixed to the upper end of the slide rod 322, and the diameter of the baffle 323 is larger than the diameter of the slide rod 322. A fixing plate 324 is also coaxially fixed to the outer wall of the slide rod 322. The fixing plate 324 is located on the side of the slide rod 322 away from the baffle 323 and is kept at a certain distance from the lower end of the slide rod 322. The fixing plate 324 is a square plate, which allows the fixing plate 324 to slide up and down along the inner wall of the limiting groove 3211. Under the limitation of the baffle 323, the fixing plate 324 will not completely detach from the limiting groove 3211.

[0037] A spring 325 is also fixed inside the limiting groove 3211. The spring 325 is sleeved on the outside of the slide rod 322, and one end of the spring 325 is fixed to the upper surface of the fixing plate 324, while the other end is fixed to the inner wall of the limiting groove 3211. A through hole 3221 is also provided on the side wall of the slide rod 322 near the baffle 323. The axis of the through hole 3221 is perpendicular to the axis of the slide rod 322, and the through hole 3221 can be aligned with the through hole 211. When the upper end of the slide rod 322 slides to the outside of the limiting groove 3211 and aligns the through hole 211 with the through hole 3221, the insert rod 31 can be inserted into the through hole 3221 and the through hole 211 and connected to the slot 121 to fix the cover plate 2.

[0038] A connecting rope 326 is also fixed on the baffle 323. The other end of the connecting rope 326 is fixedly connected to the insertion rod 31. The connecting rope 326 prevents the insertion rod 31 from being lost after it is pulled out.

[0039] Reference Figure 3 and Figure 4 When the cover plate 2 needs to be fixed at the operating port 11, the bottom of the cover plate 2 abuts against the upper surface of the housing 1, causing the lower end of the slide rod 322 to retract into the limiting groove 3211. The fixing plate 324 slides upward within the limiting groove 3211, compressing the spring 325, and the upper end of the slide rod 322 extends out of the limiting groove 3211. At this time, the insertion hole 3221 is aligned with the through hole 211 on the bent part 21. The insertion rod 31 is inserted into both the through hole 211 and the insertion hole 3221 and engages with the slot 121, thus fixing the position of the cover plate 2. When the cover plate 2 needs to be removed, the insertion rod 31 is pulled out, causing the spring 325 to rebound and drive the slide rod 322 to slide downward, giving the cover plate 2 a reaction force, causing the cover plate 2 to be lifted upward to a certain height, thus making it easy to pick up the cover plate 2 from the operating port 11.

[0040] The implementation principle of a practical valve well protective cover according to an embodiment of this application is as follows:

[0041] When the valve needs to be operated, simply move the cover plate 2 to expose the operating port 11 for operation, which is convenient and labor-saving. The water-blocking strip 12 and the bent part 21 of the cover plate 2 further reduce the amount of rainwater entering the operating port 11. The mounting mechanism 3 ensures the stability of the cover plate 2 installed on the housing 1 and reduces the possibility of the cover plate 2 being blown away by the wind. When the cover plate 2 needs to be moved, the push-out component 32 facilitates the movement of the cover plate 2 and saves manpower.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
