Description

Technical Field

[0001] The utility model relates to the technical field of vehicle speed detection, in particular to movable vehicle speed detection equipment. Background Art

[0002] When traffic police need to detect whether vehicles are speeding on a specific road section, a speed measuring device is usually installed on one side of the road. However, the existing speed measuring devices are mostly exposed to the outside, which is easy to be hit by vehicles, resulting in damage to the speed measuring device.

[0003] For example, the patent with publication number CN216595499U discloses an on-site detection device for a motor vehicle radar speed meter, including a detection shell, a top plate, and an electrical box. The top plate is fixedly connected to the top of the outer side of the detection shell, the lower part of the outer side of the detection shell is fixedly connected to the electrical box, and the middle part of the outer side of the electrical box is fixedly connected to a speed display mechanism. The detection shell includes a column and a base. The column is fixedly connected to the outer bottom of the detection shell, and the base is fixedly connected to the bottom of the column. The detection part is always in an exposed state. When a vehicle has an accident, it is easy for the vehicle to directly collide with the device, which increases the probability of damage to the detection part, shortens the life of the device, and increases the detection cost.

[0005] In order to achieve the above object, the utility model achieves the above object through the following technical solutions: a movable vehicle speed detection equipment, including a speed measuring instrument body, characterized in that: the speed measuring instrument body is equipped with a supporting protection structure, the supporting protection structure includes an electric telescopic cylinder, a base, a slot, a mounting ring, a protective sleeve, a damping cushion and a rangefinder,

[0006] The electric telescopic cylinder is installed at the center of the base, the upper end of the telescopic end of the electric telescopic cylinder is connected to the lower wall of the speed measuring instrument body, a circle of slots is arranged around the electric telescopic cylinder on the base, a plug connector is arranged at the bottom end of the installation ring corresponding to the slot, the installation ring is movably inserted into the slot through the plug connector, the installation ring is fixed to the bottom end of the protective sleeve, a circle of damping buffer pads is arranged on the outer wall of the protective sleeve, and the rangefinder is installed on the top of the damping buffer pads.

[0007] In the above solution, the slot, the mounting ring and the protective sleeve are all polygonal structures, which have better mechanical properties and stronger anti-collision ability.

[0008] In the above solution: the damping cushion is surrounded by a plurality of semi-cylindrical cushions. The semi-cylindrical cushions have better anti-collision performance.

[0009] In the above scheme: the semi-cylindrical pads of the damping buffer pad correspond to the number of sides of the protective sleeve, and a semi-cylindrical pad is arranged on one side of each protective sleeve.

[0010] In the above scheme: a distance meter is arranged on the top of the semi-cylindrical pad of each damping buffer pad.

[0011] In the above solution: the protective sleeve and the mounting ring are an integrated structure.

[0012] Compared with the prior art, the movable vehicle speed detection equipment provided by the utility model has the following beneficial effects: the device is placed on one side of the road through the base, and the height adjustment of the speed measuring instrument body is achieved by controlling the extension and retraction of the electric telescopic cylinder. The speed measuring instrument body measures the speed of vehicles traveling on the road, and at the same time, the distance meter detects the distance between the vehicle on the road and the speed measuring instrument body. When the speed measuring instrument body detects that the speed of the vehicle is too high and the distance meter detects that the distance value is less than the set target value, it is judged that the vehicle will cause a collision with the equipment. At this time, the electric telescopic cylinder is retracted until the speed measuring instrument body is received inside the protective sleeve (this control method is a prior art and will not be described in detail here). The protective sleeve and the damping cushion play a protective role for the speed measuring instrument body. When the device is hit and overturned, the damping cushion plays a shock-absorbing role, thereby reducing the probability of damage to the speed measuring instrument body.

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] Example 1: Figure 1-3 The movable vehicle speed detection equipment includes a speed measuring instrument body 1, and the speed measuring instrument body 1 is equipped with a supporting protection structure. The speed measuring instrument body 1 is an existing technology, such as the EWIG radar speed measuring instrument HT3000 mobile portable radar speed measuring and capturing equipment produced by Hangzhou Lailai Technology Co., Ltd., which will not be described in detail here.

[0019] The supporting and protective structure comprises: an electric telescopic cylinder 2, a base 3, a slot 4, a mounting ring 5, a protective sleeve 6, a damping cushion 7 and a rangefinder 8.

[0020] The electric telescopic cylinder 2 is installed at the center of the base 3. The upper end of the telescopic end of the electric telescopic cylinder 2 is connected to the lower wall of the speed measuring instrument body 1. A circle of slots 4 is arranged around the electric telescopic cylinder 2 on the base 3. A plug connector is arranged at the bottom end of the mounting ring 5 corresponding to the slot 4. The mounting ring 5 is movably inserted into the slot 4 through the plug connector. The mounting ring 5 is fixed at the bottom end of the protective sleeve 6. Preferably, the protective sleeve 6 and the mounting ring 5 are an integrated structure. A circle of damping buffer pads 7 is arranged on the outer wall of the protective sleeve 6, and the rangefinder 8 is installed on the top of the damping buffer pad 7. Preferably, the damping buffer pad 7 is surrounded by a plurality of semi-cylindrical pads. The slot 4, the mounting ring 5, and the protective sleeve 6 are all polygonal structures. The semi-cylindrical pads of the damping buffer pad 7 correspond to the number of sides of the protective sleeve 6, and a semi-cylindrical pad is arranged on one side of each protective sleeve 6. A rangefinder 8 is arranged on the top of the semi-cylindrical pad of each damping buffer pad 7.

[0021] The telescopic end of the electric telescopic cylinder 2 is installed with the speed measuring instrument body 1, and the two can be connected by welding or other methods. There is no special restriction at present. It only needs to realize the connection between the telescopic end of the electric telescopic cylinder 2 and the speed measuring instrument body 1. When in use, the protective sleeve 6 is installed on the slot 4 through the mounting ring 5 to achieve fixation. The device is placed on one side of the road through the base 3. Walking wheels can also be set on the lower side of the base 3 to realize automatic walking and change the speed measuring position. By controlling the extension and retraction of the electric telescopic cylinder 2, the height adjustment of the speed measuring instrument body 1 is achieved. The speed measuring instrument body 1 measures the speed of vehicles traveling on the road. At the same time, the rangefinder 8 detects the distance between the vehicle on the road and the speed measuring instrument body 1. When the speed measuring instrument body 1 detects that the vehicle is traveling at a too high speed and the rangefinder 8 detects that the distance value is less than the set target value, it is judged that the vehicle will cause a collision with the equipment. At this time, the electric telescopic cylinder 2 shrinks until the speed measuring instrument body 1 is received inside the protective sleeve 6. The protective sleeve 6 and the damping buffer pad 7 play a protective role for the speed measuring instrument body 1. When the device is hit and overturned, the damping buffer pad 7 plays a shock-absorbing role, which reduces the probability of damage to the speed measuring instrument body 1, extends the service life of the device, and controls the detection cost.
