Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage device technology, and in particular to a manhole cover structure for water supply and drainage in municipal engineering. Background Technology

[0002] With the rapid advancement of urbanization in my country, in order to adapt to the rapid development of urban economic production and the continuous growth of people's daily life needs, a large number of municipal engineering projects, especially water supply and drainage pipeline projects, have been constructed. The municipal drainage system includes drainage pipelines. For the needs of drainage pipeline installation and maintenance, ground outlets need to be set at certain intervals for construction and maintenance personnel to enter and exit. Each outlet is equipped with a manhole base and manhole cover.

[0003] Existing technologies, such as CN219280876U, describe a protective mesh structure for water supply and drainage well covers. This structure includes a mounting housing, a rotating box fixedly connected to one side of the upper end of the housing, a well cover on the top of the housing, and a U-shaped groove on one side of the top of the well cover. Steps are provided inside the housing, and an auxiliary switching mechanism is located on one side of the top of the U-shaped groove. A support plate is uniformly and circularly fixedly connected to the lower end of the housing. When the mounting steel plate needs to be disassembled, a handle is used to pull a lever. An adjusting rod is fixedly connected to one side of the lever. Under the pulling action, the adjusting rod slides within an adjusting groove inside a moving block. Because the adjusting groove is an inclined U-shaped groove, pulling causes the moving block to slide the fixed block into the fixed groove. Once the fixed block is away from the mounting groove, it can be removed. Therefore, this effectively increases the speed of disassembly and assembly of the mounting steel plate, making disassembly and assembly more convenient and saving time and effort.

[0004] Because the existing manhole cover structure for water supply and drainage in municipal engineering is generally hinged to the inside of the manhole base, and the connection structure between the manhole cover and the manhole base is relatively simple, its protective performance and tightness are low, which may lead to the manhole cover loosening or other dangers. Therefore, it is necessary to improve this. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the connection structure between the manhole cover and the manhole seat in the existing technology is relatively simple, and its protective performance and tightness are low, which may lead to the manhole cover loosening or other dangers. Therefore, this utility model proposes a manhole cover structure for water supply and drainage in municipal engineering.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a manhole cover structure for water supply and drainage in municipal engineering, comprising a manhole cover body, a manhole base, and a fixing hole. The manhole base is disposed at the bottom of the manhole cover body, and the fixing hole is opened on the surface of the manhole base. A drainage hole is opened on the surface of the manhole cover body, and an anti-slip pad is fixedly connected to the side of the surface of the manhole cover body near the drainage hole. A limiting support device is provided on the surface of the manhole cover body, and the limiting support device includes an installation frame. The installation frame is fixedly connected to the upper surface of the manhole cover body, and springs are fixedly connected to both sides of the inner wall of the installation frame. A limiting block is fixedly connected to the surface of the spring, and a fixing rod is fixedly connected between the two limiting blocks.

[0007] Furthermore, a positioning hole is provided at the front end of the surface of the well base, the fixing rod is aligned with the positioning hole, and an installation block is fixedly connected to the surface of the well base.

[0008] Furthermore, a rotating shaft is rotatably connected between the two mounting blocks, a telescopic rod is rotatably connected to the surface of the rotating shaft, and a mounting groove is fixedly connected to the bottom of the manhole cover body.

[0009] Furthermore, a protective net is provided on the upper surface of the well base, and protective devices are provided on both sides of the protective net, the protective devices including fixing blocks.

[0010] Furthermore, the fixing block is fixedly connected to the left and right sides of the protective net, and the surface of the well base is fixedly connected to the two sides near the protective net with fixing plates.

[0011] Furthermore, a positioning rod runs through the fixing block and the fixing plate, and the positioning rod is movably connected inside the fixing block and the fixing plate.

[0012] Furthermore, a limiting rod is fixedly connected to the surface of the well base near the positioning rod, and a movable hole is opened on the surface of the limiting rod, and a sliding rod is movably connected inside the movable hole.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a limiting support device, when the manhole cover and manhole base are fixed, the fixing rod can be aligned with the positioning hole, and the fixing rod can be fixed by the action of the spring and the limiting block, thereby fixing the manhole cover to the surface of the manhole base. At the same time, drainage can be carried out through the drainage hole, and the anti-slip mat can be used to prevent pedestrians from slipping on the manhole cover. When it is necessary to open the manhole cover to carry out construction inside, the telescopic rod can be rotated by the action of the rotating shaft on the inner wall of the mounting block, and the other end of the telescopic rod can be fixed inside the mounting groove for fixed support, thereby facilitating construction inside. The limiting support device can effectively fix the manhole cover and prevent it from shaking or shifting under the action of external forces such as wind and vehicle rolling, thereby ensuring that the manhole cover is stably covering the manhole opening and improving the practicality of the device.

[0015] 2. In this utility model, when the protective device is set up, the fixing block on the protective net and the fixing plate on the well base can be fixed by the positioning rod, and then the two limiting rods can be fixed on both sides of the positioning rod. The positioning rod can be fixed by sliding the sliding rod inside the movable hole. The protective device can effectively prevent pedestrians or workers from falling into the well due to accidental stepping or slipping, thus improving the safety of the device.

A fixing rod 604 is fixedly connected between the two limiting blocks 603.

[0026] The effect achieved by the above components is that by setting the spring 602 and the limiting block 603, the fixing rod 604 can be fixed in the positioning hole 605 to achieve further fixation.

[0027] Specifically, a positioning hole 605 is provided at the front end of the surface of the well base 2, the fixing rod 604 is aligned with the positioning hole 605, and an installation block 606 is fixedly connected to the surface of the well base 2.

[0029] Specifically, a rotating shaft 607 is rotatably connected between the two mounting blocks 606, a telescopic rod 608 is rotatably connected to the surface of the rotating shaft 607, and a mounting groove 609 is fixedly connected to the bottom of the manhole cover body 1.

[0030] The effect achieved by the above components is that the rotating shaft 607 on the inner wall of the mounting block 606 drives the telescopic rod 608 to move up and down. When it moves to the appropriate position, its other end can be fixed inside the mounting groove 609.

[0031] Specifically, a protective net 7 is provided on the upper surface of the well base 2, and protective devices 8 are provided on both sides of the protective net 7. The protective devices 8 include fixing blocks 801.
