However, in winter, the outdoor temperature is cold and the road surface is easily frozen, causing the surface of the strip weighing sensor to be frozen, making it impossible to complete the weighing of the passing vehicles. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a combined bar weighing sensor to achieve the purpose of solving the above-mentioned problems.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a combined strip weighing sensor, comprising a road surface and a strip weighing sensor, wherein the strip weighing sensor is embedded inside the road surface, and an ice-breaking mechanism is provided on the outer wall of the strip weighing sensor; The ice-breaking mechanism comprises: A fixed frame, the fixed frame is a square sleeve-shaped structure, a sliding groove is provided on the inner wall of the fixed frame, the inner wall of the sliding groove is slidably connected to the outer wall of the strip weighing sensor, a telescopic rod is fixedly connected to the bottom of the inner wall of the sliding groove, the top of the telescopic rod is fixedly connected to the bottom of the strip weighing sensor, a built-in spring is provided on the inner wall of the telescopic rod, and the fixed frame is used to support and place the strip weighing sensor; The fixed square plate is a plate-like structure, the fixed square plate is fixedly connected to the road surface, one side of the fixed square plate is fixedly connected to the outer wall of the fixed frame, and the strip weighing sensor is sealed with the inner wall of the sliding groove.

[0005] Preferably, the fixed square plate is a rectangular plate-shaped structure, the bottom of the fixed square plate is in contact with the road surface, and the number of the limiting baffles inside the fixed frame is three.

[0006] Preferably, the telescopic rod is located between the left and right limit baffles, and a connecting plate is fixedly connected to the top of the fixed frame, and the connecting plate is a rectangular plate-shaped structure.

[0007] Preferably, an inclined plate is fixedly connected to the top of the fixing frame, one side of the inclined plate is an inclined surface, and the other side of the inclined plate is in contact with the outer wall of the strip weighing sensor.

[0008] Preferably, an auxiliary mechanism is provided inside the fixing frame, and the auxiliary mechanism comprises a heat conducting plate A, and the heat conducting plate A is a rectangular plate-shaped structure.

[0009] Preferably, the heat conducting plate A is fixedly connected to the inner wall of the fixed frame, the inner wall of the fixed frame is fixedly connected to the heat conducting plate B, and the bottom of the heat conducting plate B is fixedly connected to the top of the heat conducting plate A.

[0010] Preferably, a heat conducting plate C is fixedly connected to the inner wall of the inclined plate, the bottom of the heat conducting plate C is fixedly connected to the top of the heat conducting plate B, and the heat conducting plate C, the heat conducting plate B and the heat conducting plate A are all made of heat conducting materials.

[0011] Preferably, a slope is formed on one side of the inclined plate, and the slope is an inclined surface. The heat conducting plate A is used to transfer the heat generated by the friction between the bar weighing sensor and the heat conducting plate to the heat conducting plate C through the heat conducting plate B.

[0012] The present invention provides a combined bar weighing sensor having the following beneficial effects: 1. The present invention sets an ice-breaking mechanism, so that when each vehicle passes by the strip weighing sensor, the strip weighing sensor can be lifted and pressed. By lifting and lowering the strip weighing sensor back and forth, the ice attached to the outside of the strip weighing sensor is effectively squeezed against the fixed square plate next to it when the strip weighing sensor descends, thereby producing an ice-breaking effect. Once the ice on the outer wall of the strip weighing sensor is broken, the ice at other positions of the strip weighing sensor will be broken together. Then, even in an icy state when the temperature is too low, the ice can be automatically broken to avoid the problem that the strip weighing sensor cannot accurately detect the vehicle weight due to freezing.

[0013] 2. The present invention provides an ice-breaking mechanism. When the bar-shaped weighing sensor is lifted and lowered, the friction between the outer wall of the bar-shaped weighing sensor and the inner wall of the fixed frame will also cause the bar-shaped weighing sensor itself to heat up to a certain extent, thereby effectively melting the residual ice attached to the top of the bar-shaped weighing sensor. As the vehicle wheels travel, the residual ice is broken, thereby achieving stable sensing of vehicle weighing. 3. The present invention provides an ice-breaking mechanism, and the inclined plates on both sides of the strip weighing sensor are used to guide the rain and snow water from the outside downward through the inclined surfaces and slopes on the inclined plates, so as to prevent the water from accumulating between the inclined plates above the fixed frame and the strip weighing sensor and being frozen into ice at low temperature, thereby affecting the sensing detection function of the strip weighing sensor; 4. The present invention sets an ice-breaking mechanism to push the fixed frame to squeeze the air inside the fixed frame for compression. Through the working process of the bar weighing sensor being continuously compressed and then reset, the air inside the fixed frame is continuously compressed, and then continuously heated up to generate heat. The temperature of the enclosed space will directly heat up the bar weighing sensor, and the friction heat generated between the outer wall of the bar weighing sensor and the inner wall of the fixed frame will further enhance the melting effect of the ice on the outer wall of the bar weighing sensor, thereby reducing the situation where the bar weighing sensor is frozen and cannot perform stable vehicle weighing detection.

[0014] 5. The present invention sets an auxiliary mechanism. When the inner wall of the fixed frame slides, the heat conducting plate A will be rubbed against the inner wall of the fixed frame. The temperature generated when the heat conducting plate A is rubbed will be conducted to the heat conducting plate B through the heat conducting plate A, and then to the heat conducting plate C through the heat conducting plate B, and finally to the inclined plate through the heat conducting plate C, so that the bar weighing sensor and the inclined plate are heated synchronously to prevent the problem of continuous ice formation on the inclined plate and freezing the two sides of the bar weighing sensor.

DETAILED DESCRIPTION

[0017] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a combined strip weighing sensor, comprising a road surface 1 and a strip weighing sensor 2, wherein the strip weighing sensor 2 is embedded inside the road surface 1, and an ice-breaking mechanism 3 is arranged on the outer wall of the strip weighing sensor 2; The ice-breaking mechanism 3 comprises: The fixing frame 301 is a square sleeve-shaped structure. A sliding groove 302 is provided on the inner wall of the fixing frame 301. The inner wall of the sliding groove 302 is slidably connected to the outer wall of the strip-shaped weighing sensor 2. A telescopic rod 304 is fixedly connected to the bottom of the inner wall of the sliding groove 302. The top of the telescopic rod 304 is fixedly connected to the bottom of the strip-shaped weighing sensor 2. A built-in spring is provided on the inner wall of the telescopic rod 304. The fixing frame 301 is used to support and place the strip-shaped weighing sensor 2. The fixed square plate 305 is a plate-like structure, the fixed square plate 305 is fixedly connected to the road surface 1 through 306, one side of the fixed square plate 305 is fixedly connected to the outer wall of the fixed frame 301, and the strip weighing sensor 2 and the inner wall of the sliding groove 302 are in a sealed state; When a vehicle is traveling on the road surface 1 and passes through the strip weighing sensor 2 on the road surface 1, the strip weighing sensor 2 will be pressed, and the vehicle weight will be automatically sensed by sensing the pressure of the vehicle wheels and the vehicle speed measurement by multiple strip weighing sensors 2, so as to realize automatic detection of the vehicle weight of each vehicle on the road surface 1 through multiple strip weighing sensors 2; Example 2: Please refer to Figure 1-9Based on the first embodiment, the present invention provides a technical solution: the fixed square plate 305 is a rectangular plate structure, the bottom of the fixed square plate 305 is in contact with the surface of the road surface 1, and the number of the limiting baffles 303 inside the fixed frame 301 is three.

[0018] The telescopic rod 304 is located between the left and right limit baffles 303 . The top of the fixed frame 301 is fixedly connected with a connecting plate 308 , which is a rectangular plate-shaped structure.

[0019] The top of the fixed frame 301 is fixedly connected with an inclined plate 309, one side of the inclined plate 309 is an inclined surface, and the other side of the inclined plate 309 is in contact with the outer wall of the strip weighing sensor 2; When the tire of the vehicle passes over the strip weighing sensor 2, the strip weighing sensor 2 will be pressed down first, pushing the telescopic rod 304 at the bottom and the built-in spring inside the telescopic rod 304 to deform, causing the telescopic rod 304 to retract, and the strip weighing sensor 2 will slide down in the sliding groove 302 in the fixed frame 301, and abut against the limit baffle 303. After the strip weighing sensor 2 abuts against the limit baffle 303, it will continue to complete the sensing detection of the vehicle weight. When the strip weighing sensor 2 slides down on the inner wall of the fixed frame 301, the two sides of the strip weighing sensor 2 and the inner wall of the fixed frame 301 continue to slide, so that in winter, the road surface 1 is frozen and the strip weighing sensor 2 is frozen and sealed due to the ice. When the vehicle passes by the strip weighing sensor 2, the sensing accuracy of the bar weighing sensor 2 to the vehicle is reduced. The strip weighing sensor 2 is greatly dropped, and thus cannot be used. When the strip weighing sensor 2 is pressed by the vehicle, the inner wall of the fixed frame 301 can be slid down before detection. When each vehicle passes the strip weighing sensor 2, the strip weighing sensor 2 can be lifted and pressed. By lifting and lowering the strip weighing sensor 2 back and forth, the ice attached to the outside of the strip weighing sensor 2 is effectively squeezed with the fixed square plate 305 next to it when the strip weighing sensor 2 is lowered, so as to produce an ice-breaking effect. Once the ice on the outer wall of the strip weighing sensor 2 is broken, the ice at other positions of the strip weighing sensor 2 will be broken together. Then, even in the freezing state when the temperature is too low, the ice will be automatically broken to avoid the problem that the strip weighing sensor 2 cannot accurately detect the vehicle weight due to freezing. While the bar weighing sensor 2 is rising and falling, the friction between the outer wall of the bar weighing sensor 2 and the inner wall of the fixing frame 301 will also cause the bar weighing sensor 2 to heat up to a certain extent, thereby effectively melting the residual ice attached to the top of the bar weighing sensor 2, and breaking the residual ice as the vehicle wheels move, thereby achieving stable sensing of vehicle weighing; Example 3: Please refer to Figure 1-11On the basis of the first and second embodiments, the present invention provides a technical solution: an auxiliary mechanism 4 is arranged inside the fixing frame 301, and the auxiliary mechanism 4 includes a heat conducting plate A401, and the heat conducting plate A401 is a rectangular plate-shaped structure.

[0020] The heat conducting plate A401 is fixedly connected to the inner wall of the fixing frame 301 , the heat conducting plate B402 is fixedly connected to the inner wall of the fixing frame 301 , and the bottom of the heat conducting plate B402 is fixedly connected to the top of the heat conducting plate A401 .

[0021] A heat conducting plate C403 is fixedly connected to the inner wall of the inclined plate 309 , and the bottom of the heat conducting plate C403 is fixedly connected to the top of the heat conducting plate B402 . The heat conducting plate C403 , the heat conducting plate B402 , and the heat conducting plate A401 are all made of heat conducting materials.

[0022] A slope 404 is formed on one side of the inclined plate 309. The slope 404 is an inclined surface. The heat conducting plate A401 is used to transfer the heat generated by the friction between the bar-shaped weighing sensor 2 and the heat conducting plate 401 to the heat conducting plate C403 through the heat conducting plate B402. The inclined plates 309 on both sides of the bar weighing sensor 2 are used to guide the rain and snow water from the outside downward through the inclined surface and the slope 404 on the inclined plates 309, so as to prevent the water from accumulating between the inclined plates 309 above the fixing frame 301 and the bar weighing sensor 2 and being frozen into ice at low temperature, thereby affecting the sensing detection function of the bar weighing sensor 2; When the bar weighing sensor 2 is reciprocatedly pressed and lifted by the vehicle, the bar weighing sensor 2 and the inner wall of the fixed frame 301 slide against each other and are in a sealed state, so that the bar weighing sensor 2 will continuously squeeze the air between the bottom and the fixed frame 301. After each vehicle passes over the bar weighing sensor 2, it will push the fixed frame 301 to squeeze the air in the fixed frame 301 to compress it. Through the working process of the bar weighing sensor 2 being continuously compressed and reset, the air inside the fixed frame 301 is continuously compressed, and then continuously heated up to generate heat. The temperature of the enclosed space will directly heat up the bar weighing sensor 2, and the friction heat generated between the outer wall of the bar weighing sensor 2 and the inner wall of the fixed frame 301 will further enhance the melting effect of the ice on the outer wall of the bar weighing sensor 2, and reduce the situation where the bar weighing sensor 2 is frozen and cannot stably detect the vehicle weighing. When the bar weighing sensor 2 slides on the inner wall of the fixed frame 301, it will rub the heat conducting plate A401. The temperature generated when the heat conducting plate A401 is rubbed will be conducted to the heat conducting plate B402 through the heat conducting plate A401, and then to the heat conducting plate C403 through the heat conducting plate B402, and finally to the inclined plate 309 through the heat conducting plate C403, thereby synchronously heating the bar weighing sensor 2 and the inclined plate 309 to prevent the problem of continuous ice formation on the inclined plate 309 and freezing the two sides of the bar weighing sensor 2.

[0023] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
