Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of roadblocks, and in particular relates to a municipal roadblock. Background Art
[0002] During municipal construction, a large number of sewer manholes will be set up on the sidewalks and even on the blind paths. When workers are repairing the sewers or manhole covers on the road, they need to set up roadblocks around the construction site to block passers-by. Currently, cones or interception frames are used as roadblocks to block passers-by, but in the actual construction process, it mainly relies on passers-by to automatically detour after observing, which is not suitable for the blind. The blind cannot visually observe the existence of roadblocks when passing by. When blocking with cones, the blind may directly pass through the gap between the cones and walk straight to the sewer manhole. When blocking with interception frames, the blind may collide with the interception frames, and even the support frame extending outward from the bottom of the interception frame may trip the blind.

[0015] See also Figure 1-Figure 3 The utility model provides the following technical solutions: a municipal roadblock, comprising four inner support columns 1 symmetrically distributed in pairs, the tops of the four inner support columns 1 are provided with hexagonal protective handrails 2, the fence area of the hexagonal protective handrails 2 is larger than the fence area of the four inner support columns 1, and the tops of the hexagonal protective handrails 2 are fixedly connected with a plurality of circularly distributed raised directional arrows 21, one side of the two inner support columns 1 located on the same side is provided with a blind path covering pad 3, the blind path covering pad 3 is embedded with a pressure sensor 31, and a voice broadcast alarm 4 is provided between the two inner support columns 1 located on the same side, and the pressure sensor 31 is electrically connected to the voice broadcast alarm 4.
[0016] In this embodiment: when the staff inspects the municipal manhole, the staff installs the inner support column 1 and the hexagonal protective handrail 2 around the manhole, and lays the blind path covering pads 3 on both sides on the road. When the manhole is located on the blind path, the blind path covering pad 3 is laid on the blind path, and the engaging groove 32 corresponds to the raised position of the blind path. When the device is in use, when normal pedestrians pass by, they will bypass the device when they see it. When a blind person or a person who looks down at a mobile phone steps on the blind path covering pad 3, the pressure sensor 31 detects the pressure change and then transmits the signal to the voice broadcast alarm 4, which emits a sound to remind the personnel, and the prompt content can be "Construction ahead, hold the handrail and bypass When a person approaches the hexagonal protective handrail 2, the inner supporting column 1 located on the inner side supports the hexagonal protective handrail 2 with a larger blocking range, so that the blind person approaching the wellhead can be intercepted more safely, and the rod frame structure of the device itself can be prevented from contacting the legs and feet of the blind person, thereby avoiding tripping of the walking blind person. Then the blind person holds the hexagonal protective handrail 2 according to the prompt, and is guided by the distribution path of the hexagonal protective handrail 2 itself and the raised directional arrow 21, and assists the blind person to bypass the maintenance section. The blind person's safe passage is ensured by prompting, protecting and guiding the blind person in stages. The raised directional arrow 21 is set to protrude so that the person's hand can feel the indicated direction of the raised directional arrow 21 more clearly.
[0017] The top ends of the four inner support columns 1 are fixedly connected with an extended connecting rod 11, and the four extended connecting rods 11 are fixedly connected to the hexagonal protective handrails 2; by providing the extended connecting rods 11, the connection between the inner support columns 1 and the hexagonal protective handrails 2 can be facilitated, and the extended connecting rods 11 extend upward at an angle so that the hexagonal protective handrails 2 are horizontally away from the inner support columns 1, and people will not kick the inner support columns 1 when moving. The four inner support columns 1 and the extended connecting rods 11 support the hexagonal protective handrails 2 at four points, thereby improving the stability of the hexagonal protective handrails 2.
[0018] A supporting cross bar 12 is fixedly connected between the two inner supporting columns 1 on the same side, and a voice broadcast warning device 4 is installed on the top of the supporting cross bar 12; by providing the supporting cross bar 12 to play a supporting and connecting role, it is convenient to install the blind path covering pad 3 and the voice broadcast warning device 4, and at the same time improve the stability of the inner supporting column 1.
[0019] A midpoint interception ball 22 is fixedly connected to the top of the hexagonal protective handrail 2, and the midpoint interception ball 22 is located at the intersection of the short rods on both sides of the hexagonal protective handrail 2; the midpoint interception ball 22 is set to intercept and remind the blind, and cooperate with the blind's own sense of direction to remind the blind that they have detoured to the opposite road, thereby preventing the blind from walking in a circle along the path of the hexagonal protective handrail 2.
[0020] A plurality of engaging and giving way grooves 32 are provided at the bottom end of the blind path covering pad 3, and a soft connecting belt 33 is fixedly connected to one side of the blind path covering pad 3, and the soft connecting belt 33 is fixedly connected to the supporting cross bar 12; by providing the engaging and giving way grooves 32, the protrusions on the blind path can be given way, so that the blind path covering pad 3 can be better fitted to the blind path, and by providing the soft connecting belt 33, the connection between the blind path covering pad 3 and the supporting cross bar 12 can be facilitated, and the blind path covering pad 3 can be bent and deformed. When the device is in the storage state, the staff flips the blind path covering pad 3 and stores it under the hexagonal protective handrail 2, and the blind path covering pads 3 on both sides are overlapped to reduce the space occupied by the device.
[0021] The working principle and use process of the utility model are as follows: when inspecting the municipal wellhead, the staff installs the inner support column 1 and the hexagonal protective handrail 2 around the wellhead, and lays the blind path covering pads 3 on both sides on the road. When the wellhead is located on the blind path, the blind path covering pads 3 are laid on the blind path. When normal pedestrians pass by, they will bypass the device when they see it. When a blind person or a person who looks down at a mobile phone steps on the blind path covering pad 3, the pressure sensor 31 detects the pressure change and then transmits the signal to the voice broadcast alarm 4, which emits a sound to remind the personnel. When the personnel are close to the hexagonal protective handrail, the voice broadcast alarm 4 will emit a sound to remind the personnel. When the protective handrail 2 is used, the inner supporting column 1 located on the inside supports the hexagonal protective handrail 2 with a larger blocking range, so that the blind person approaching the wellhead can be intercepted more safely, and the rod frame structure of the device itself can be prevented from contacting the legs and feet of the blind person, thereby avoiding tripping of the walking blind person. Then the blind person holds the hexagonal protective handrail 2 according to the prompt, and relies on the distribution path of the hexagonal protective handrail 2 itself and the raised directional arrow 21 to guide the blind person to bypass the maintenance section. When the device is in the storage state, the staff flips the blind path covering pad 3 and stores it under the hexagonal protective handrail 2. The blind path covering pads 3 on both sides are overlapped to reduce the space occupied by the device.
