TECHNICAL FIELD

[0001] The present application relates to the technical field of drainage structures, in particular to a municipal pavement drainage structure. BACKGROUND

[0002] At present, the municipal pavement drainage structure is an important component to ensure that the rainwater and surface water of the road surface and the surrounding area can be effectively drained, so as to avoid the inconvenience or danger caused by the accumulated water to traffic and pedestrians. In the related art, the municipal pavement drainage structure includes a rainwater well, which is an opening provided on the road for collecting rainwater. An access cover needs to be provided at the well mouth of the rainwater well to block the well mouth, so as to prevent pedestrians from accidentally falling into the rainwater well. However, most access covers are usually independent of the rainwater well, which leads to the fact that the access cover is prone to theft. Once the access cover is lost, it will bring great safety hazards to pedestrians. CONTENT OF THE UTILITY MODEL

[0003] The present application provides a municipal pavement drainage structure which can effectively prevent the theft and loss of the access cover, and further improves the safety of the drainage structure.

[0004] The municipal pavement drainage structure provided by the present application adopts the following technical scheme:

[0005] A municipal pavement drainage structure includes a mounting seat for fixedly mounting on the top of a rainwater well, and an access cover provided on the mounting seat. The access cover is rotatably provided on one side of the mounting seat. A limiting frame is provided on the inner side wall of the mounting seat. An anti-theft lock is provided on the access cover. The limiting frame is used to cooperate with the lock tongue of the anti-theft lock. When the access cover is closed on the mounting seat, the lock tongue of the anti-theft lock is rotated to below the limiting frame. At this time, under the cooperation of the anti-theft lock and the limiting frame, the access cover is locked on the mounting seat. An intercepting assembly is further provided on the mounting seat. The intercepting assembly includes a filter frame. Drainage holes are provided on the filter frame.

[0006] Preferably, the intercepting assembly further includes a lifting seat which is lifted on the mounting seat. The filter frame is provided on the lifting seat. A linkage assembly is provided between the lifting seat and the access cover. One end of the linkage assembly is connected with the access cover, and the other end of the linkage assembly is connected with the lifting seat. When the access cover is flipped, the linkage assembly will drive the lifting seat to be lifted synchronously.

[0007] Preferably, the linkage assembly includes a fixed pulley which is rotatably provided on the mounting seat. A lifting rope is wound on the fixed pulley. One end of the lifting rope is connected and fixed with the access cover, and the other end of the lifting rope is connected and fixed with the lifting seat.

[0008] Preferably, the linkage assembly further comprises a ratchet wheel coaxially arranged outside the fixed pulley, and a pawl rotatably arranged on the mounting base, the pawl and the ratchet wheel being in interfitting engagement; the pawl is used to limit the direction rotation of the ratchet wheel to drive the lifting base to descend.

[0009] Preferably, the lifting base is provided with a through hole for a worker to pass through, and a horizontal plate is detachably mounted on the inner side wall of the through hole; the filter frame is provided with a plurality of positioning insertion rods, and the horizontal plate is provided with a plurality of positioning insertion holes corresponding to the positioning insertion rods one by one, and the positioning insertion rods are respectively inserted into the corresponding positioning insertion holes.

[0010] Preferably, the inner side wall of the well cover is rotatably provided with a support rod, and the limiting frame is provided with a plurality of insertion slots arranged in sequence at intervals, and the insertion slots are used for inserting the support rod out of the well cover and limiting the support rod on the limiting frame.

[0011] Preferably, the inner side wall of the well cover is provided with a plurality of reinforcing ribs arranged in sequence at intervals.

[0012] In summary, the present application has at least one of the following beneficial technical effects:

[0013] Under the cooperation of the anti-theft lock and the limiting frame, the well cover can be locked on the mounting base, thereby greatly improving the anti-theft performance of the well cover, and since the well cover and the mounting base are connected with each other and become an integral whole, the probability of losing the well cover is effectively reduced.

[0014] The filter frame is conveniently detached from the lifting base by the plug-in fixing mode. When the well cover is turned outwards, the lifting base will be driven by the linkage assembly to ascend synchronously with the well cover; conversely, when the well cover is closed downwards, the lifting base will be driven by the linkage assembly to descend synchronously with the well cover, thereby facilitating the cleaning personnel to take out the filter frame loaded with garbage from the well.

[0015] When the well cover is turned outwards, the interfitting of the pawl and the ratchet wheel can effectively prevent the lifting base from falling, and when it is needed to reset the lifting base, the pawl can be turned out of the ratchet wheel to complete the unlocking.

DETAILED DESCRIPTION

[0021] The application will be further described in detail below with reference to the accompanying drawings.

[0022] The application discloses a municipal pavement drainage structure.

[0023] With reference to Figure 1 , Figure 2 , the municipal pavement drainage structure comprises a mounting seat 1 for being fixedly installed on the top of a rainwater well, and a well lid 2 arranged outside the mounting seat 1, the well lid 2 being used for plugging the well mouth of the rainwater well. One side of the well lid 2 is rotatably arranged on the mounting seat 1, the rotating shaft of the well lid 2 is arranged in the horizontal direction, and the maximum overturning angle of the well lid 2 is 90°. When the well lid 2 is overturned to 90° in the direction away from the mounting seat 1, the rotating shaft of the well lid 2 cannot continue to rotate under the limitation of the mounting seat 1.

[0024] As shown in Figure 2 , Figure 3 and Figure 4 , a limiting frame 10 is fixedly installed on the inner side wall of the mounting seat 1, and two groups of anti-theft locks 3 are fixedly installed on the well lid 2, the limiting frame 10 being used for cooperating with the lock tongues of the anti-theft locks 3. When the well lid 2 is covered on the mounting seat 1, the lock tongues of the anti-theft locks 3 are rotated to below the limiting frame 10, and the well lid 2 is locked on the mounting seat 1 under the cooperation of the anti-theft locks 3 and the limiting frame 10. Therefore, the anti-theft performance of the well lid 2 can be greatly improved, and in addition, since the well lid 2 and the mounting seat 1 are connected with each other and become a whole, the probability of loss of the well lid 2 is effectively reduced.

[0025] As shown in Figure 3 , Figure 4As shown, the mounting base 1 is further provided with an intercepting assembly 4, which comprises four guide rods 401 fixedly installed on the mounting base 1, and each guide rod 401 is parallel to each other and vertically arranged. The intercepting assembly 4 further comprises a lifting seat 42 movably arranged outside each guide rod 401, and the lifting seat 42 is arranged below the mounting base 1 along the height direction of the guide rod 401. The bottom of the lifting seat 42 is provided with a through hole 420 for the construction personnel to pass through, and the construction personnel can smoothly enter the rainwater well through the through hole 420.

[0026] As shown in Figure 3 , Figure 4 The lifting seat 42 is detachably provided with a plurality of horizontal plates 421 arranged on the inner wall of the through hole 420, and the end of the horizontal plate 421 is inserted and fixed on the lifting seat 42 from top to bottom. The intercepting assembly 4 further comprises a filter frame 40 for intercepting and filtering garbage, and the filter frame 40 is placed in the lifting seat 42, and the bottom of the filter frame 40 is provided with a plurality of drainage holes 41. The bottom of the filter frame 40 is fixedly provided with a plurality of positioning insertion rods 400, and the horizontal plate 421 is provided with a plurality of positioning insertion holes 422 corresponding to the positioning insertion rods 400, and the positioning insertion rods 400 are respectively inserted and fixed in the corresponding positioning insertion holes 422. The filter frame 40 is detachable from the lifting seat 42 by using the insertion and fixing mode.

[0027] As shown in Figure 3 , Figure 4 The lifting seat 42 and the well lid 2 are provided with two groups of linkage assemblies 5, and the linkage assemblies 5 are symmetrically arranged on both sides of the lifting seat 42. One end of the linkage assembly 5 is connected with the well lid 2, and the other end of the linkage assembly 5 is connected with the lifting seat 42. When the well lid 2 is turned outward, the lifting seat 42 will be driven by the linkage assembly 5 to rise synchronously with the well lid 2; conversely, when the well lid 2 is closed downward, the lifting seat 42 will be driven by the linkage assembly 5 to descend synchronously with the well lid 2. Thus, the cleaning personnel can take out the filter frame 40 provided with garbage from the rainwater well.

[0028] As shown in Figure 3 , Figure 4As shown, the linkage assembly 5 includes a fixed pulley 50 rotatably arranged on the inner side wall of the mounting seat 1, the fixed pulley 50 is located above the lifting seat 42, and the rotation axis of the fixed pulley 50 is parallel to the rotation axis of the manhole cover 2. The fixed pulley 50 is wound with a lifting rope 51, one end of the lifting rope 51 is fixedly connected with the inner side wall of the manhole cover 2, and the other end of the lifting rope 51 is fixedly connected with the lifting seat 42. The linkage assembly 5 further includes a ratchet wheel 52 coaxially arranged outside the fixed pulley 50, and a pawl 53 rotatably arranged on the mounting seat 1, the pawl 53 is located on one side of the ratchet wheel 52, and the pawl 53 and the ratchet wheel 52 are mutually inserted and matched. The pawl 53 is used to limit the direction rotation of the ratchet wheel 52 driving the lifting seat 42 to descend. When the manhole cover 2 is turned outward, the mutual cooperation of the pawl 53 and the ratchet wheel 52 can effectively prevent the lifting seat 42 from falling, and when it is necessary to reset the lifting seat 42, the pawl 53 can be turned out from the outside of the ratchet wheel 52 to complete the unlocking.

[0029] As shown in Figure 3 , Figure 4 , two groups of support rods 6 are rotatably arranged on the inner side wall of the manhole cover 2, and the support rods 6 are symmetrically arranged on both sides of the manhole cover 2. The outer side wall of the limiting frame 10 towards each support rod 6 is provided with a plurality of insertion slots 100 arranged in sequence, and the insertion slots 100 are located on the rotation path of each opposite support rod 6. The insertion slot 100 is used for inserting the end of the support rod 6 turned out from the manhole cover 2 to limit the limiting frame 10, and the support rod 6 is used to support the manhole cover 2, thereby effectively preventing the manhole cover 2 from accidentally tipping in the direction close to the mounting seat 1. The inner side wall of the manhole cover 2 is also integrally formed with a plurality of reinforcing ribs 20 arranged in sequence, and the reinforcing ribs 20 can greatly enhance the pressure resistance of the manhole cover 2.

[0030] The implementation principle is: under the cooperation of the anti-theft lock 3 and the limiting frame 10, the manhole cover 2 can be locked on the mounting seat 1. Thus, the anti-theft performance of the manhole cover 2 can be greatly improved, and in addition, since the manhole cover 2 and the mounting seat 1 are connected with each other, they become a whole, thereby effectively reducing the probability of the manhole cover 2 being lost. The plug-in fixed way is convenient for dismounting the filter frame 40 from the lifting seat 42. When the manhole cover 2 is turned outward, the lifting seat 42 will be driven by the linkage assembly 5 to rise synchronously with the manhole cover 2; conversely, when the manhole cover 2 is closed downward, the lifting seat 42 will be driven by the linkage assembly 5 to descend synchronously with the manhole cover 2. Thus, it is convenient for the cleaning personnel to take out the filter frame 40 filled with garbage from the rainwater well. When the manhole cover 2 is turned outward, the mutual cooperation of the pawl 53 and the ratchet wheel 52 can effectively prevent the lifting seat 42 from falling, and when it is necessary to reset the lifting seat 42, the pawl 53 can be turned out from the outside of the ratchet wheel 52 to complete the unlocking.

[0031] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
