Technical Field
[0001] The utility model relates to the technical field of municipal engineering, and specifically to an anti-blocking manhole cover for municipal engineering. Background Art
[0002] Manhole covers are closed objects at the top of entrances and exits leading to underground facilities. They are required to be installed wherever public facilities such as tap water, telecommunications, electricity, gas, heat, fire protection, and sanitation are installed. When there is heavy rainfall in areas with lower geographical locations in the city, there will generally be accumulated water, which is discharged into the underground through manhole covers to clear the accumulated water.
[0003] However, it is difficult for existing manhole covers to filter impurities in the accumulated water, which causes the accumulated water mixed with impurities to flow into the underground pipes through the manhole covers and easily cause blockage. It is difficult for people to clean the blocked underground pipes in time, which causes some manhole covers to be difficult to continue draining. Therefore, a kind of anti-blocking manhole cover for municipal engineering is needed to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide an anti-blocking manhole cover for municipal engineering, which solves the problem in the prior art that the existing manhole covers are difficult to filter impurities in the accumulated water, resulting in the accumulated water mixed with impurities flowing through the manhole covers into the underground pipes and easily causing blockage. Since it is difficult for people to clean the blocked underground pipes in time, some manhole covers are difficult to continue to drain water.
[0005] The utility model provides the following technical solutions: an anti-blocking manhole cover for municipal engineering, comprising a manhole cover, a plurality of drain outlets are provided at the top of the manhole cover, a plurality of slots are provided at the side end of the manhole cover, a plurality of jacks are provided at the side end of each of the slots, a plurality of interception boxes are provided at the bottom end of the manhole cover, a plug plate is fixedly connected to the top of each of the interception boxes, a plurality of installation slots are provided inside each of the plug plates, and a fixing mechanism for installing the interception box is provided inside each of the installation slots.
[0006] As a preferred embodiment of the above technical solution, a plurality of filter holes are provided through the bottom and a plurality of side surfaces of each interception box.
[0007] As a preferred embodiment of the above technical solution, the fixing mechanism includes a spring, which is fixedly connected to the inner side end of the mounting groove, the side end of the spring is fixedly connected to a rectangular plate, the side end of the rectangular plate is fixedly connected to an insertion rod, and the top end of the rectangular plate is fixedly connected to a pull plate.
[0008] As a preferred embodiment of the above technical solution, each of the plug boards is inserted into each slot, and each of the plug rods is inserted into each plug hole.
[0009] As a preferred embodiment of the above technical solution, the outer shape of each of the plug boards is L-shaped, and the shape of each of the slots is L-shaped.
[0010] As a preferred embodiment of the above technical solution, a plurality of limit frames are fixedly connected to the bottom end of the manhole cover.
[0011] As a preferred embodiment of the above technical solution, the side end of each interception box is fixedly connected to a limit plate, and each limit plate is inserted into each limit frame.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model provides a fixing mechanism and can simultaneously drive the rectangular plates at both ends to press the springs to contract by pinching the pull plates at both ends inwards. At this time, the insertion rod moves toward the direction inside the installation slot, and the insertion plate can be conveniently inserted into the slot by translation. At this time, the limit plate is also inserted into the limit frame. After the installation of the insertion plate is completed, the insertion rod automatically aligns with the position of the insertion hole. After the pull plate is released, the spring rebounds against the rectangular plate, driving the insertion rod to be inserted into the insertion hole, thereby facilitating the installation and fixation of the interception box. At this time, since the outer shape of each of the insertion plates is L-shaped and the shape of each of the slots is L-shaped, the slot can support the insertion plate, and the limit frame can support the limit plate, thereby improving the stability of the interception box after installation.
[0014] By setting up the interception box, after each interception box is installed at the bottom of the manhole cover, when it rains, the accumulated water is discharged into the interception box through the sewer outlet. Since the bottom and several sides of the interception box are penetrated by a number of filter holes, the accumulated water can be filtered so that the accumulated water can be discharged into the underground pipe normally. At the same time, impurities and garbage can be intercepted to prevent impurities and garbage from being discharged into the underground pipe together with the accumulated water, thereby avoiding blockage of the underground pipe. Therefore, there is no need to clean the underground pipe. It is only necessary to regularly disassemble the interception box and clean the impurities inside to avoid the situation where some manhole covers will become difficult to continue draining.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0021] like Figure 1-4 As shown, the utility model provides a technical solution: an anti-blocking manhole cover for municipal engineering, comprising a manhole cover 1, a plurality of drain ports 101 are provided at the top of the manhole cover 1, a plurality of slots 103 are provided at the side end of the manhole cover 1, a plurality of jacks 104 are provided at the side end of each slot 103, a plurality of interception boxes 2 are provided at the bottom end of the manhole cover 1, a plurality of filter holes 201 are provided through the bottom end and a plurality of side surfaces of each interception box 2, when it rains, the accumulated water is discharged into the interception box 2 through the drain ports 101, because a plurality of filter holes 201 are provided through the bottom end and a plurality of side surfaces of the interception box 2, the accumulated water can be filtered so that the accumulated water can be discharged into the underground pipe normally, and at the same time, impurities and garbage can be intercepted to avoid impurities and garbage being discharged into the underground pipe together with the accumulated water, thereby avoiding the blockage of the underground pipe. Therefore, there is no need to clean the underground pipe, and it is only necessary to regularly disassemble the interception box 2 and clean the impurities inside it, so as to avoid the situation that some manhole covers 1 will be difficult to continue to drain.
[0022] Furthermore, the top of each interception box 2 is fixedly connected with a plug plate 202, and a plurality of installation grooves 203 are opened inside each plug plate 202. A fixing mechanism for installing the interception box 2 is provided inside each installation groove 203. The bottom end of the manhole cover 1 is fixedly connected with a plurality of limit frames 102, and the side end of each interception box 2 is fixedly connected with a limit plate 204, and each limit plate 204 is inserted into each limit frame 102. In implementation, through the setting of the fixing mechanism, the installation and fixation of the interception box 2 can be easily completed, and the disassembly of the interception box 2 can be easily completed.
[0023] As an implementation method in this embodiment, Figure 2 and Figure 4As shown, the fixing mechanism includes a spring 3, the spring 3 is fixedly connected to the inner side end of the mounting groove 203, the side end of the spring 3 is fixedly connected to a rectangular plate 301, the side end of the rectangular plate 301 is fixedly connected to an insertion rod 302, each insertion plate 202 is inserted in each slot 103, each insertion rod 302 is inserted in each insertion hole 104, the outer shape of each insertion plate 202 is L-shaped, the shape of each slot 103 is L-shaped, and the top of the rectangular plate 301 is fixedly connected to a pull plate 303. During implementation, by pinching the pull plates 303 at both ends inward, the rectangular plates 301 at both ends can be simultaneously driven to press the spring 3 to shrink, and at this time the insertion rod 302 moves toward the mounting groove 203 The upper and lower parts of the block 202 are moved in the same direction, and the plug board 202 can be easily inserted into the slot 103. At the same time, the limit plate 204 is also inserted into the limit frame 102. After the plug board 202 is installed, the plug rod 302 automatically aligns with the position of the socket 104. After the pull plate 303 is released, the spring 3 rebounds against the rectangular plate 301, driving the plug rod 302 to be inserted into the socket 104, thereby completing the installation and fixation of the interception box 2. At this time, since the shape of each plug board 202 is L-shaped and the shape of each slot 103 is L-shaped, the slot 103 can support the plug board 202, and the limit frame 102 can support the limit plate 204, thereby improving the stability of the interception box 2 after installation.

At this time, the insertion rod 302 moves toward the direction inside the installation slot 203. At this time, it is convenient to translate the insertion plate 202 into the slot 103, and the limit plate 204 is also inserted into the limit frame 102. At this time, after the installation of the insertion plate 202 is completed, the insertion rod 302 automatically aligns with the position of the socket 104. After the pull plate 303 is released, the spring 3 rebounds against the rectangular plate 301, driving the insertion rod 302 to be inserted into the socket 104, thereby completing the installation and fixation of the interception box 2. At this time, since the shape of each insertion plate 202 is L-shaped, and the shape of each slot 103 is L-shaped, the slot 103 can align with the insertion plate 202. The plate 202 supports, and the limit frame 102 can support the limit plate 204, so as to improve the stability of the interception box 2 after installation. At this time, after each interception box 2 is installed at the bottom of the manhole cover 1, when it rains, the accumulated water is discharged into the interception box 2 through the sewer port 101. Since the bottom and several sides of the interception box 2 are penetrated by a plurality of filter holes 201, the accumulated water can be filtered so that the accumulated water can be discharged into the underground pipe normally, and at the same time, the impurities and garbage can be intercepted to avoid the impurities and garbage and the accumulated water from being discharged into the underground pipe together, thereby avoiding the blockage of the underground pipe. Therefore, there is no need to clean the underground pipe. It is only necessary to regularly disassemble the interception box 2 and clean the impurities inside, so as to avoid the situation that some manhole covers 1 will be difficult to continue to drain.
