Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of manhole protection, in particular to a simple anti-overflow device. Background Art
[0002] At present, urban rainwater pipes and sewage pipes often overflow, causing large areas of water accumulation on the road, which has a great impact on residents' travel and living environment. In addition, the overflowing manholes are accompanied by a very pungent odor, affecting the visual and taste perception of pedestrians. Utility Model Content
[0003] In view of the deficiencies in the prior art, the present invention provides a simple anti-overflow device. In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:
[0004] A simple anti-overflow device is used to prevent overflow from a manhole. The manhole is provided with a manhole cover, including two connecting wells, a sealing plate spliced together to seal the manhole, a connecting rod and a floating ball. The connecting wells are symmetrically arranged on both sides of the manhole, and a connecting vertical groove is arranged between the connecting well and the manhole. The sealing plate is hinged in the vertical groove, and the connecting rod is arranged in the vertical groove. One end of the connecting rod is hinged to the bottom end of the sealing plate, and the other end is hinged to the floating ball. The floating ball is arranged in the connecting well.
[0005] Furthermore, a vertical guide column is arranged in the connecting well, and a guide groove which is slidably matched with the guide column is opened on the float.
[0006] Furthermore, an annular convex plate is provided in the manhole, and the bottom end of the convex plate is in conflict with the top end of the sealing plate.
[0007] Furthermore, sealing rubber is provided on the edges of the sealing plates.
[0008] Furthermore, the sealing plate is arranged in a boss shape, and the edge of the sealing plate is in contact with the manhole.
[0009] Furthermore, a hook is provided in the manhole, and an anti-falling net is hung on the hook.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] When the manhole is blocked, the water level in the manhole rises, driving the float to rise, thereby pushing the sealing plate to close through the connecting rod. The closed sealing plate seals the manhole, thereby preventing the water in the manhole from overflowing onto the ground. The structure is simple and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] The utility model is further described below in conjunction with the accompanying drawings and embodiments:
[0013] Figure 1 This is a schematic diagram of the top view of the structure of an embodiment of the utility model;
[0014] Figure 2 It is a schematic diagram of the transverse cross-section structure of an embodiment of the utility model.
[0015] In the above drawings: manhole 1, manhole cover 2, connecting well 3, sealing plate 4, connecting rod 5, float 6, vertical groove 7, guide column 8, convex plate 9, sealing rubber 10, anti-fall net 11. DETAILED DESCRIPTION
[0016] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0017] like Figure 1 , Figure 2 As shown, the utility model provides a technical solution, a simple anti-overflow device, used to prevent overflow of a manhole 1, the manhole 1 is provided with a manhole cover 2, including two connecting wells 3, a sealing plate 4 spliced together to block the manhole 1, a connecting rod 5 and a floating ball 6, the connecting wells 3 are symmetrically arranged on both sides of the manhole 1, and a connecting vertical groove 7 is arranged between the connecting well 3 and the manhole 1, the sealing plate 4 is hinged in the vertical groove 7, the connecting rod 5 is arranged in the vertical groove 7, one end of the connecting rod 5 is hinged to the bottom end of the sealing plate 4, and the other end is hinged to the floating ball 6, and the floating ball 6 is arranged in the connecting well 3. The manhole 1 is selected to be round, and the floating ball 6 is selected to be a hollow plastic ball with large buoyancy.
[0018] Working principle: When the manhole 1 is blocked, the water level in the manhole 1 rises, driving the float 6 to rise, thereby pushing the sealing plate 4 to close through the connecting rod 5. The closed sealing plate 4 blocks the manhole 1. The higher the water level, the greater the supporting force of the float 6 on the sealing plate 4, thereby preventing the water in the manhole 1 from overflowing the ground. After the subsequent pipe network water level drops, the water in the manhole 1 will also flow out by itself, and the float 6 will drop, driving the sealing plate 4 to open, and the manhole 1 will work normally. The structure is simple and the cost is low.
[0019] Furthermore, Figure 1 , Figure 2 As shown, a vertical guide column 8 is provided in the communication well 3, and a guide groove is provided on the float 6 to slide with the guide column 8. Through the cooperation between the guide groove and the guide column 8, the float 6 rises more stably and smoothly.
[0020] Furthermore, Figure 2 As shown, an annular convex plate 9 is arranged in the manhole 1, and the bottom end of the convex plate 9 conflicts with the top end of the sealing plate 4. The setting of the convex plate 9 limits the sealing plate 4, making the sealing plate 4 more airtight and avoiding leakage.
[0021] Furthermore, Figure 1 , Figure 2 As shown, the edges of the sealing plate 4 are provided with sealing rubber 10 to improve the sealing performance of the sealing plate 4.
[0022] Furthermore, Figure 2 As shown, the sealing plate 4 is configured to be convex, and the edge of the sealing plate 4 is in contact with the manhole 1. The convex sealing plate 4 is limited by the manhole 1, and the sealing performance between the sealing plate 4 and the manhole 1 is also increased.
[0023] Furthermore, Figure 2 As shown, a hook is provided in the manhole 1, and an anti-falling net 11 is hung on the hook to improve the safety of the manhole 1.
[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
