Description

Technical Field

[0001] This utility model relates to the field of drainage gate technology, and in particular to a drainage gate valve for underground pump rooms. Background Technology

[0002] A sluice gate for draining floodwater, also known as a drainage gate, is typically located at the outlet of water flowing into rivers in flood-prone areas. Drainage gates on irrigation canals are used to remove excess water from the canals, such as during flood season when floodwaters are drained from the catchment area of ​​the canal system; these are generally called spillway gates.

[0003] However, in the existing technology, when the existing drainage gate valve is in a position with limited space during the rotation and opening process, the top handle will rise as the valve is turned due to the top constraint. As it rises, the rotation range will decrease due to the space limitation, which makes it inconvenient for operators and is not conducive to practical application. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide a drainage gate valve for a well pump room, which solves the problem that when the drainage gate valve is in a small space during the rotation and opening process, the top handle will rise due to the top of the valve. As a result, the rotation range will decrease due to the space limitation during the rising process, which makes it inconvenient for the operator to operate and is not conducive to practical application.

[0005] The technical solution of this utility model is as follows: a drainage gate valve for a well pump room includes a valve body, a through groove on the outer side of the valve body, a blocking groove on the top of the valve body, a blocking plate slidably connected inside the blocking groove, a support frame fixedly connected to the top of the valve body, a rotating cylinder rotatably connected to the top of the support frame, a moving block slidably connected inside the rotating cylinder, a bolt fixedly connected to the bottom of the moving block, the bottom of the bolt being threadedly connected to the support frame, the bolt passing through the support frame and rotatably connected to the blocking plate, a slider fixedly connected to the outer side of the moving block, and two sliding grooves on the outer side of the rotating cylinder, with the slider slidably connected to both grooves.

[0006] With the above technical solution, when the equipment is in a confined space and the baffle needs to be moved, the rotating drum can be rotated to drive the slider to rotate via the slide groove. The slider's rotation drives the moving block to rotate, which in turn drives the bolt to rotate, causing the bolt to connect with the threaded support frame. This causes the baffle to slide inside the baffle groove, allowing the liquid to flow through the through groove after the baffle moves upward. Similarly, when it is necessary to close the baffle, rotating the drum in the opposite direction will cause the baffle to block the flow. During the rotation of the drum, the space constraints that prevent the bolt from being lifted will hinder the operator's operation.

[0007] In a preferred embodiment, a limiting plate is fixedly connected to the inner wall of the support frame, and a through hole is provided on the outer side of the limiting plate and on the outer side of the bolt.

[0008] Through the above technical solution, during the upward movement of the baffle plate, the limiting plate prevents the baffle plate from completely detaching from the baffle groove.

[0009] In a preferred embodiment, both sides of the valve body are fixedly connected to a conveying pipe, which communicates with the inside of the through groove, and one end of the conveying pipe is fixedly connected to a flange.

[0010] The above technical solution facilitates the flow of liquids by connecting the delivery pipe to the flange.

[0011] In a preferred embodiment, a base is fixedly connected to the bottom of the valve body, and a fixing plate is fixedly connected to the bottom of the base. Fixing holes are provided at equal intervals on the bottom of the fixing plate.

[0012] The above technical solution uses fixing holes at the bottom of the fixing plate to facilitate the fixed connection of the equipment.

[0013] In a preferred embodiment, a filter plate is fixedly connected inside the conveying pipe, and a handle is fixedly connected to the top of the rotating drum.

[0014] The above technical solution allows the liquid to be filtered through the filter plate, and the handle makes it easy for the operator to rotate the drum.

[0015] In a preferred embodiment, a sealing ring is fixedly connected to the end of the through groove that contacts the baffle plate.

[0016] The sealing ring can improve the sealing effect of the baffle plate through the above technical solution.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] In this invention, when the equipment is in a confined space and the baffle needs to be moved, the rotating drum is rotated. During the rotation, the rotating drum drives the slider to rotate via the slide groove. The slider rotates, which in turn drives the moving block to rotate. The moving block then drives the bolt to rotate, causing the bolt to connect with the threaded support frame. This causes the baffle to slide inside the baffle groove. After the baffle moves upward, the liquid can flow through the through groove. Similarly, when it is necessary to close the baffle, the rotating drum is rotated in the opposite direction to block the baffle. During the rotation of the rotating drum, the space limitation can be avoided from affecting the operator's operation when the bolt is lifted.

[0019] During the upward movement of the baffle plate, the limiting plate prevents the baffle plate from completely detaching from the baffle groove. The connection between the conveying pipe and the flange facilitates the flow of liquid. The fixing holes at the bottom of the fixing plate facilitate the fixed connection of the equipment. The filter plate can filter the liquid. The handle makes it easy for the operator to rotate the drum. The sealing ring can improve the sealing effect of the baffle plate. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3As shown, this utility model provides a technical solution: including a valve body 1, a through groove 4 on the outer side of the valve body 1, a blocking groove 3 on the top of the valve body 1, a blocking plate 8 slidably connected inside the blocking groove 3, a support frame 2 fixedly connected to the top of the valve body 1, a rotating cylinder 5 rotatably connected to the top of the support frame 2, a moving block 6 slidably connected inside the rotating cylinder 5, a bolt 7 fixedly connected to the bottom of the moving block 6, the bottom of the bolt 7 being threadedly connected to the support frame 2, the bolt 7 passing through the support frame 2 and rotatably connected to the blocking plate 8, a slider 12 fixedly connected to the outer side of the moving block 6, and two sliding grooves 9 on the outer side of the rotating cylinder 5, with the slider 12 slidably connected to both sliding grooves 9.

[0028] In this embodiment, when the equipment is in a confined space and the baffle plate 8 needs to be moved, the rotating drum 5 is rotated. During the rotation, the rotating drum 5 drives the slider 12 to rotate via the slide groove 9. During the rotation of the slider 12, the moving block 6 is driven to rotate, which in turn drives the bolt 7 to rotate, so that the bolt 7 is threadedly connected to the support frame 2. This causes the baffle plate 8 to slide inside the baffle groove 3. After the baffle plate 8 moves upward, the liquid can flow through the through groove 4. Similarly, when it is necessary to close the device, the rotating drum 5 is rotated in the opposite direction to block the baffle plate 8. During the rotation of the rotating drum 5, the operation of the operator can be avoided due to space constraints when the bolt 7 is raised.

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, a limiting plate 10 is fixedly connected to the inner wall of the support frame 2, and a through hole 11 is provided on the outer side of the limiting plate 10 and on the outer side of the bolt 7.

[0030] In this embodiment, during the upward movement of the blocking plate 8, the blocking plate 10 prevents the blocking plate 8 from completely disengaging from the blocking groove 3.

[0031] like Figure 1 , Figure 2 , Figure 3 As shown, both sides of the valve body 1 are fixedly connected to a conveying pipe 13, which is connected to the inside of the through groove 4. One end of the conveying pipe 13 is fixedly connected to a flange 14.

[0032] In this embodiment, the connection between the delivery pipe 13 and the flange 14 facilitates the flow of liquid.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, a base 16 is fixedly connected to the bottom of the valve body 1, and a fixing plate 17 is fixedly connected to the bottom of the base 16. Fixing holes 18 are equidistantly opened at the bottom of the fixing plate 17.

[0034] In this embodiment, the device is fixedly connected by fixing holes 18 at the bottom of the fixing plate 17.

[0035] like Figure 1 , Figure 2 , Figure 3 As shown, filter plates 15 are fixedly connected inside the conveying pipe 13, and a handle 19 is fixedly connected to the top of the rotating drum 5.

[0036] In this embodiment, the liquid can be filtered by the filter plate 15, and the handle 19 makes it easy for the operator to rotate the drum 5.

[0037] like Figure 1 , Figure 2 , Figure 3 As shown, a sealing ring is fixedly connected to the end of the through groove 4 that contacts the baffle plate 8.

[0038] In this embodiment, the sealing ring can improve the sealing effect of the baffle plate 8.

[0039] Working principle:

[0040] like Figure 1 , Figure 2 , Figure 3 As shown, when the equipment is in a confined space, and the baffle plate 8 needs to be moved, the rotating drum 5 is rotated. During the rotation of the rotating drum 5, the slider 12 is driven to rotate through the slide groove 9. During the rotation of the slider 12, the moving block 6 is driven to rotate, and the moving block 6 drives the bolt 7 to rotate, so that the bolt 7 is threadedly connected to the support frame 2. This causes the baffle plate 8 to slide inside the baffle groove 3. After the baffle plate 8 moves upward, the liquid can flow through the through groove 4. Similarly, when it is necessary to close, the rotating drum 5 is rotated in the opposite direction so that the baffle plate 8 can block it. During the rotation of the rotating drum 5, the operation of the operator can be avoided due to space constraints when the bolt 7 is raised.

[0041] During the upward movement of the baffle plate 8, the limiting plate 10 prevents the baffle plate 8 from completely detaching from the blocking groove 3. The connection between the conveying pipe 13 and the flange 14 facilitates the flow of liquid. The fixing hole 18 at the bottom of the fixing plate 17 facilitates the fixed connection of the equipment. The filter plate 15 can filter the liquid. The handle 19 makes it easy for the operator to rotate the drum 5. The sealing ring can improve the sealing effect of the baffle plate 8.

[0042] Finally, it should be noted that the above-described 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 the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
