Description

Technical Field

[0001] The utility model relates to the technical field of municipal facilities, in particular to a municipal safety manhole. Background Art

[0002] There are many sewer pipes in urban construction. There should be an outlet leading to the ground at regular intervals for these sewer pipes. The section from the pipe to the ground is called a manhole. A manhole cover is arranged on the manhole opening to make the manhole parallel to the ground and maintain the normal passage of vehicles and pedestrians on the road surface. However, once the manhole cover is damaged or stolen, it is easy for pedestrians to fall into the manhole, which seriously threatens the lives of pedestrians.

[0003] Generally, the manhole cover plays a role in closing the manhole to prevent pedestrians from stepping into the empty space and falling. Generally, when in use, the manhole cover is directly placed and clamped in the placement groove. Therefore, when the manhole cover is under heavy pressure, the pressure will directly act on the manhole, which will cause the manhole cover to warp. At the same time, after the manhole is deformed due to heavy pressure, the placement of the manhole cover will not be stable enough, which will affect its use. Since the stress point is mainly on the side, the middle part of the manhole cover is not well supported. Therefore, when under heavy pressure, the manhole cover is extremely easy to be damaged.

[0004] Therefore, a municipal safety manhole is proposed. Content of the Utility Model

[0024] Such as Figures 1-4As shown in the figure, a municipal safety type manhole includes a manhole body 1. Inside the manhole body 1, a manhole cover assembly 2 is placed. The manhole cover assembly 2 includes a manhole cover body 201, a first clamping ring 202 and a second clamping ring 203. A through hole 2011 is opened on the manhole cover body 201. An installation groove 2012 is opened at the top end of the manhole cover body 201. A support member 4 for supporting the manhole cover body 201 is arranged on the manhole cover body 201. An installation frame 6 is arranged at the bottom end of the manhole cover body 201. The support member 4 includes a lead screw 402 rotatably arranged on the manhole cover body 201 and a fixed block 401 arranged at the top end inside the installation frame 6. The lead screw 402 is rotatably arranged at the top end of the fixed block 401. A sliding block 403 is threadedly sleeved on the lead screw 402. A first connecting rod 404 and a second connecting rod 405 are respectively hinged on one side of the sliding block 403 and the fixed block 401 which correspond to each other. The other end of the first connecting rod 404 is hinged with an extrusion support plate 407. An anti-slip pad 408 is arranged on one side of the extrusion support plate 407. A connecting slider 406 is slidably arranged on the extrusion support plate 407. The connecting slider 406 is hinged with the second connecting rod 405. The first connecting rod 404 and the second connecting rod 405 are cross-distributed, and the first connecting rod 404 and the second connecting rod 405 on the same side are hinged; specifically, by arranging a driving member 5, the lead screw 402 can be driven to rotate, so that the sliding block 403 can be driven to slide, making it close to or away from the fixed block 401. During this process, the two extrusion support plates 407 will also approach or move away from each other. After the manhole cover assembly 2 is placed on the manhole body 1, the mutual separation between the two extrusion support plates 407 can extrude the inner wall of the manhole body 1, so that the manhole cover assembly 2 can be supported, thus reducing the pressure of the manhole cover assembly 2 on the manhole body 1. After being subjected to heavy pressure, the manhole cover assembly 2 will not easily lift. At the same time, due to the action of the support member 4, the pressure is evenly distributed on the manhole cover assembly 2, so that it can be prevented from being damaged, and at the same time, the pressure on the manhole body 1 can be reduced, preventing it from being damaged and affecting the stability of the manhole cover assembly 2.

[0025] As Figure 2 shown, a first stepped groove 101 adapted to the first clamping ring 202 is opened on the manhole body 1. A first shock pad 2021 is arranged at the bottom end of the first clamping ring 202. A reflective strip 2022 is arranged at the top end of the first clamping ring 202.

[0026] As Figure 2As shown in the figure, a second stepped groove 102 adapted to the second clamping ring 203 is further formed on the manhole body 1, and a second shock pad 2031 is provided at the bottom end of the second clamping ring 203; specifically, the first shock pad 2021 and the second shock pad 2031 provided can play a good role in shock absorption and noise reduction, so that it can be avoided that it makes a large noise when in use and disturbs the residents. The first stepped groove 101 and the second stepped groove 102 are arranged in a stepped manner. After the manhole cover assembly 201 is placed thereon, it can play a good supporting role for it.

[0027] As Figure 2 shown in the figure, a sealing cover 3 is movably arranged at the opening of the installation groove 2012. The sealing cover 3 and the manhole cover body 201 are connected by bolts 301, and a warning sign 302 is arranged at the top end of the manhole cover body 201; specifically, the sealing cover 3 can play a role in sealing the installation groove 2012. At the same time, its material is hard and it will not easily deform and be damaged. The sealing cover 3 can be fixed by the bolts 301 provided, and the warning sign 302 provided can play a warning role for the masses to avoid maliciously opening it.

[0028] As Figure 3 shown in the figure, a driving member 5 for driving the lead screw 402 to rotate is arranged inside the installation groove 2012. The driving member 5 includes a worm gear 501 arranged at the top end of the lead screw 402 and a worm 502 rotatably arranged inside the installation groove 2012. The worm 502 meshes with the worm gear 501; specifically, the worm 502 and the worm gear 501 have self-locking property. Therefore, after the extrusion support plate 407 is moved to the corresponding position, its position can be fixed to ensure its extrusion force.

[0029] As Figure 4 shown in the figure, the sliding block 403 is slidably arranged inside the mounting bracket 6.

[0030] To sum up: The driving member 5 provided can drive the lead screw 402 to rotate, so that the sliding block 403 can be driven to slide, making it approach or move away from the fixed block 401. During this process, the two extrusion support plates 407 will also approach or move away from each other. After the manhole cover assembly 2 is placed on the manhole body 1, the two extrusion support plates 407 moving away from each other can extrude the inner wall of the manhole body 1, so that it can play a supporting role for the manhole cover assembly 2, thus reducing the pressure of the manhole cover assembly 2 on the manhole body 1. After being subjected to heavy pressure, the manhole cover assembly 2 will not easily tilt. At the same time, due to the action of the support member 4, the pressure is evenly distributed on the manhole cover assembly 2, so that it can be avoided from being damaged, and at the same time, the pressure on the manhole body 1 can also be reduced to avoid its damage and affect the stability of the manhole cover assembly 2.
