Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 6 As shown, this embodiment discloses a manhole cover with warning and self-draining functions. Its main body is the same as a general manhole cover, consisting of a base 6 and a cover plate 5. The base 6 is installed on the ground, and the cover plate 5 is installed on the base 6 for opening and closing the manhole. The cover plate 5 has a through hole 2 (for drainage and operation of opening and closing the cover plate 5). The base 6 is equipped with a guide wheel 11, a support leg 8, and a pin 9 with a reset function. The top surface of the cover plate 5 has a storage groove containing a warning rod 4. One end of the cover plate 5 is hinged to the base 6, and the other end is locked to the base 6 by the front end of the pin 9. After the pin 9 is unlocked, the cover plate 5 can be opened both upwards and downwards. One end of the warning rod 4 is hinged to... On the cover plate 5, the warning rod 4 is completely located in the storage slot when retracted and is locked by a locking device when upright (the locking device can be a pin, a latch, a flexible buckle, etc., which are common structures and are not shown in the figure); the upper part of the warning rod 4 is equipped with a warning sign 1 and a water level line 7 distributed along the line; a buoyancy component 3 is slidably installed on the warning rod 4; one end of the buoyancy component 3 is connected to a pull rope 10; the other end of the pull rope 10 extends into the well seat 6 along the inside of the warning rod 4 and passes around the guide wheel 11 before connecting to the rear end of the pin 9; when the buoyancy component 3 floats to a certain position, the pin 9 is unlocked by pulling the pull rope 10 (the buoyancy of the buoyancy component 3 is greater than the reset force of the pin 9), and the cover plate 5 opens downward and rests against the support leg 8.

[0024] The working method of the above-mentioned manhole covers with warning and self-draining functions is as follows: Figure 1 As shown, under normal circumstances, the warning bar 4 is completely retracted into the storage slot, and the cover plate 5 is locked to the manhole base 6 by the front end of the pin 9, without affecting road traffic; when there is a possibility of water accumulation or there is already a certain degree of water accumulation, such as Figure 2 and Figure 3 As shown, the warning pole 4 is erected and locked, and the warning sign 1 is positioned above the water surface, indicating the location of the manhole cover and warning of danger to passing vehicles and pedestrians. The buoyancy component 3 rises along the warning pole 4 as the water level rises. The mark on the water level line 7 where the buoyancy component 3 is located indicates the current water level. When the water level exceeds a certain threshold, such as... Figure 4As shown, the buoyant member 3 pulls the plug 9 to unlock by the pull rope 10, the cover plate 5 is opened downward and rests on the leg 8, realizing quick drainage (the through hole 2 of the cover plate 5 itself cannot realize quick drainage, only when the cover plate 5 is opened can quick drainage be realized), after the accumulated water is drained, the buoyant member 3 is first moved upward, the front end of the plug 9 is retreated by the pull rope 10, and the cover plate 5 is lifted to the locking position (the through hole 2 can be used to put in a crowbar, and the cover plate 5 can be easily lifted), then the buoyant member 3 is released, the plug 9 is reset and inserted into the cover plate 5 through the front end to lock the cover plate 5, and finally the warning rod 4 is lowered.

[0025] In order to better drain water, as shown in Figure 3 and Figure 4 In this embodiment, the well seat 6 is provided with a flow guide 12, when the cover plate 5 is opened downward and rests on the leg 8, the inclined surface of the cover plate 5 points to the flow guide 12, and the surface of the flow guide 12 facing the cover plate 5 is an arc surface. The flow guide 12 can smoothly guide the accumulated water flowing downward to both sides, improving the efficiency of the accumulated water flowing.

[0026] The opening water level of the cover plate 5 is related to the length of the pull rope 10 when it is pulled straight, in general, the length of the pull rope 10 when it is pulled straight can be set according to the preset opening water level of the cover plate 5, but in order to conveniently and flexibly adjust the opening water level of the cover plate 5, it is better to set the length of the pull rope 10 when it is pulled straight to be adjustable: as shown in Figure 5 In this embodiment, the buoyant member 3 is slidably installed on the warning rod 4 through the connecting rod 13 and the sliding block 15, the connecting rod 13 is fixedly connected to the buoyant member 3, the sliding block 15 is located in the sliding groove of the warning rod 4 and is matched with the side surface of the sliding groove on both sides, and the front surface is provided with a threaded hole 16, the buoyant member 3 is located outside the sliding groove, the connecting rod 13 extends into the sliding groove and is matched with the threaded hole 16 of the sliding block 15, the connecting rod 13 is fixedly connected with a rope winding wheel 14, the rope winding wheel 14 is located in the sliding groove, and the pull rope 10 is connected to the rope winding wheel 14; only the buoyant member 3 needs to be twisted, the pull rope 10 can be wound and unwound through the rope winding wheel 14, and then the length of the pull rope 10 when it is pulled straight is adjusted, and the thread locking force between the connecting rod 13 and the sliding block 15 is greater than the reset force of the plug 9.

[0027] The plug 9 with the reset function belongs to the conventional technology, as shown in Figure 6 In this embodiment, the plug 9 is installed in the pin shell 17 and extends out of the pin shell 17 at both ends, the pin shell 17 is installed on the well seat 6, the plug 8 is sleeved with a reset spring 19 in the pin shell 17, and the reset spring 19 acts on the flange 18 of the plug 9. The reset spring 19 can be arranged on the side of the flange 18 close to the pull rope 8, or the reset spring 19 can be arranged on both sides of the flange 18.

[0028] In order to enhance the warning effect, a reflective material can be pasted on the warning sign 1; a reflective material can also be pasted on the buoyant member 3, which not only warns, but also facilitates observation of the current water level.

[0029] For the buoyant member 3, it can adopt wear-resistant plastic material, and has one or more cavities inside.

[0030] From the above, the well lid can warn the passing vehicles and pedestrians of danger under the water accumulation condition, display the water level, and automatically and quickly drain water when reaching a certain water level, and can not affect the passing under normal conditions.
