Description

TECHNICAL FIELD

[0001] The utility model discloses a double sensor weighing device belongs to weighing device technical field. BACKGROUND

[0002] Runoff sediment is a key issue in the field of ecological environment. In the process of soil erosion, runoff carries a large amount of sediment, which can lead to soil fertility decline, affect vegetation growth and ecological system stability. For example, in mountainous areas, a large amount of sediment loss can destroy the vegetation cover of the mountain, causing landslides, mudslides and other geological disasters, and causing devastating damage to the surrounding ecological environment. At the same time, runoff sediment entering rivers, lakes and other water bodies can cause water turbidity, affecting the survival environment of aquatic organisms and disrupting the balance of water ecosystems.

[0003] For water conservancy projects, the content and variation of runoff sediment are crucial. Sediment accumulation in reservoirs and river channels can reduce the effective storage capacity of reservoirs, reduce the water storage capacity of water conservancy projects, and affect the normal functioning of flood control, irrigation, power generation and other functions. For example, some reservoirs in the Yellow River Basin have been severely affected by sediment accumulation, and a large amount of manpower and material resources are needed for dredging work. Therefore, accurate measurement of the content of runoff sediment is of great significance for the planning, design and operation management of water conservancy projects.

[0004] The weighing device of the present cannot meet the process of soil and water conservation monitoring, the traditional weighing device is nothing more than the electronic scale and platform scale on the market, but the scale frame in the above weighing device is usually placed on the tray during weighing, the function is too single, the structure is not stable enough, the measurement cannot meet the requirements, and the measurement can only be in a specific occasion, cannot be applied in other fields, which brings inconvenience for subsequent in-depth understanding of the mechanism and influencing factors of soil erosion. For example, the existing patent CN216524343U (application date: October 11, 2021) discloses a double sensor weighing device, which comprises a base, a weighing sensor, a groove plate and a weighing disc, two weighing sensors are horizontally and symmetrically arranged on both sides of the base, so that the stress ends of the two weighing sensors are symmetrically arranged, the stress ends of the two weighing sensors are centrally arranged towards each other, and the fixed ends of the two weighing sensors are respectively arranged on both sides of the base. Two groove plates are fixed on the stress ends of the two weighing sensors, and each groove plate is provided with a plurality of stress beads; the bottom of the weighing disc is arranged above the two groove plates and in contact with the plurality of stress beads to maintain stress balance. However, there are still some defects in the prior art, such as:

[0005] 1. During prolonged weighing use, because the sensor is always subjected to only vertical force, the sensor will deform, causing the force-bearing ends of the sensor at both ends to sink and tilt towards the middle, causing deformation of the entire weighing frame under the weighing pan, which leads to changes in the measurement accuracy of the sensor and inaccurate measurement results.

[0006] 2. The weighing device does not have a height-adjustable knob at the bottom, which limits its use to flat areas. Utility Model Content

[0007] This invention provides a dual-sensor weighing device to address problems such as inaccurate measurement accuracy, deformation of the weighing frame, and limited application area in weighing devices.

[0008] To solve the above-mentioned technical problems, the specific technical solution of this utility model is as follows:

[0009] A dual-sensor weighing device, such as Figures 1-4 As shown, it includes a base 7, a weighing frame 1, a crossbeam 2, a load cell 4, a base 5, and a junction box 6;

[0010] Multiple base feet 7 are symmetrically arranged at the bottom of the weighing frame 1; multiple crossbeams 2 are provided inside the weighing frame 1, and two crossbeams 2 form a group. The upper surface of the crossbeam 2 is provided with a groove 3, and the two ends of the crossbeam 2 are fixedly connected to the weighing frame 1; a load cell 4 is provided in the middle and rear end of the groove 3 on the upper surface of the crossbeam 2, and two load cells 4 form a group and are located on the same horizontal plane; a base 5 is provided at the front end of one of the crossbeams 2 in a group, and a junction box 6 is provided on the upper surface of the base 5; wherein, the two load cells 4 in a group are electrically connected to one end of the junction box 6, and the other end of the junction box 6 is electrically connected to the measurement and control system for transmitting measurement data.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model provides a dual-sensor weighing device that is easy to disassemble and assemble. It adopts a stainless steel weighing frame and is equipped with a stainless steel crossbeam, making the overall structure of the weighing device robust and stable, and with a stronger weighing capacity. The use of stainless steel in both components enhances the rigidity of the weighing device, preventing the possibility of deformation of the weighing frame during use. The weighing device of this utility model can be used in any area where weighing is required, avoiding situations where the weighing frame cannot be used due to changes in the measurement area and environment, and thus avoiding situations where weighing cannot be performed due to the unusable weighing frame.

[0013] 2. The weighing frame has multiple adjustable feet at the bottom, so the weighing device of this invention can be used to measure the object to be weighed in both flat and complex environments. For example, when measuring the runoff volume, sediment content and sediment concentration of runoff in different regions, the weight value must be measured. When measuring runoff sediment, the placement of the weighing frame will face various complex environmental problems. Therefore, when placing it in a complex environment, the multiple feet can be adjusted to make it level, so as to meet the needs of use and measurement in different measurement environments.

[0014] 3. In this utility model, a dual-weighing sensor weighing method is adopted to obtain multiple sets of measured weight data, making the measured weight data results more accurate, reliable, and impartial, with higher measurement precision, thereby meeting the requirements for precise measurement. Furthermore, both weighing sensors are connected to a junction box, which contains a circuit board capable of setting the weight, making the measured weight data more accurate. Since the other end of the junction box is electrically connected to the measurement and control system, the measured weight data from both weighing sensors can be transmitted to the measurement and control system. This allows for the calculation of multiple data points required during operation, improving work efficiency.

[0015] 4. This utility model can be equipped with multiple sets of crossbeams and weighing sensors according to actual measurement needs, thereby meeting the need for simultaneous measurement of multiple identical or different objects to be weighed, making weighing faster and measurement data more accurate; and it can weigh any object that needs to be weighed, simply by placing the object to be weighed above a set of weighing sensors at the same time, so that the weighing device is not limited to measuring the content of only one or a few objects to be weighed, and its application is more extensive.

[0020] The present invention will be further described below.

[0021] like Figure 1As shown, the base 7 is movably connected to the weighing frame 1 via threads, and the height of the weighing frame 1 can be adjusted by adjusting the threads upwards or downwards.

[0022] The material of frame 1 is stainless steel.

[0023] The material of crossbeam 2 is stainless steel.

[0024] The measurement and control system includes a data acquisition module 8, a wireless transmission module 9, and a monitoring platform 10.

[0025] The data acquisition module 8 can collect data measured by the two weighing sensors 4; the wireless transmission module 9 can transmit the measured data collected by the data acquisition module 8 to the monitoring platform 10 in a timely manner; the monitoring platform 10 can perform calculations based on the received data.

[0026] Specifically, such as Figures 1-4 As shown, when measuring runoff sediment in a certain area, the weighing frame 1 is placed in this area. By adjusting the base feet 7 upwards or downwards, the symmetrical frame 1 is leveled so that the upper surface of the weighing frame 1 is on the same horizontal plane to meet the measurement requirements. Then, the sediment collection bucket is placed directly above a set of weighing sensors 4 to collect runoff sediment in a certain area at different times. The weight value is then measured by the set of weighing sensors 4. Each set of weighing sensors 4 contains two weighing sensors 4, and each weighing sensor 4 will measure its corresponding weight value. The measured weight value is transmitted to the measurement and control system in real time. The data acquisition module 8 in the measurement and control system will transmit the collected weight value data to the monitoring platform 10 through the wireless transmission module 9. Finally, the monitoring platform 10 will calculate the runoff volume, sediment volume, and sediment content of the runoff sediment in this area based on the received weight value data, thus completing the measurement of runoff sediment in this area.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
