Description

Technical Field

[0001] The utility model belongs to the technical field of water quality detection, and specifically relates to a water quality detection device applied to water conservancy and hydropower construction. Background Art

[0002] Hydropower is a renewable and pollution-free clean energy. It plays an extremely important role in my country's energy development history and supports the sustainable development of the economy and society. During the construction of water conservancy and hydropower, it is necessary to conduct periodic and continuous testing of water resources at the construction site and its surroundings to prevent pollution and damage to the surrounding environment.

[0003] Water quality sampling is one of the important links in water quality testing. During the water quality sampling process, people need to take transportation (such as a boat) to the sampling area and then conduct manual sampling. However, the water environment of water conservancy and hydropower construction is generally deep and the water surface is relatively open. The traditional manual sampling method is not only inefficient, but also has great safety hazards. In recent years, with the rapid development of drones, the solution of sampling with drones carrying sampling buckets has gradually replaced manual sampling, especially for the water environment faced by water conservancy and hydropower construction. It not only improves the sampling efficiency, but also eliminates the safety hazards of manual sampling. However, it still has the following shortcomings: In order to ensure the accuracy of the sampled samples, the sampling bucket generally needs to be rinsed with samples (such as water in the sampling area) 2 to 3 times. The technical solution of drones carrying sampling buckets in the prior art can only achieve one sampling, that is, the sample water body is put into the sampling bucket, and it is impossible to achieve rinsing and then sampling in one sampling process.

[0027] Example

[0028] like Figures 1 to 5 As shown, this embodiment provides a water quality detection device for water conservancy and hydropower construction. The device uses an unmanned aerial vehicle (UAV) body as the main carrier, and a connecting piece is arranged at the bottom of the UAV body, and a mounting box is installed through the connecting piece. The UAV body can adopt a mature UAV structure currently on the market, and the connecting piece can adopt a fixed connecting piece or a telescopic connecting piece. The connecting piece, the UAV and the mounting box are preferably connected in a detachable bolted manner. The fixed connecting piece (such as Figure 1 As shown) does not have telescopic ability and is mainly used for sampling in shallow waters. Telescopic connectors (e.g. electric telescopic rods, such as Figure 2 As shown in the figure, it can be retracted and is mainly used for sampling in deeper waters. The connecting parts and their connections with the mounting box and the main body of the UAV are existing mature structures, so they will not be described here. This embodiment is mainly based on the structural improvement of the mounting box and the sampling barrel.

[0029] In this embodiment, the mounting box includes a box body and a partition arranged in the box body, and the box body is divided into a motor compartment and a transmission compartment by the partition. A driving motor and a power supply battery are arranged in the motor compartment, and a flip transmission mechanism is arranged in the transmission compartment, and the driving motor and the flip transmission mechanism are connected; the driving motor provides driving power, preferably a wireless control motor, or a motor that realizes wireless control in combination with a PCB control board, which is an existing mature product, so it will not be described here. The flip transmission mechanism is connected to the sampling bucket to execute the flipping and pouring of the sampling bucket, and the box body adopts a sealed and waterproof design.

[0030] In this embodiment, the flip transmission mechanism includes a driving shaft, a first flip rod assembly connected to the driving shaft as an integral structure, a second flip rod assembly used in conjunction with the first flip rod assembly through a linkage mechanism, and an output shaft connected to the second flip rod assembly as an integral structure and connected to the sampling barrel; wherein the drive motor is fixed in the motor compartment of the box body, and the end of the driving shaft of the flip transmission mechanism passes through the partition of the box body and is connected to the output shaft of the drive motor through a coupling.

[0031] The linkage mechanism is connected to the first flip rod assembly and the second flip rod assembly respectively. The first flip rod assembly is driven by a driving motor, which serves as an active component, and then drives the second flip rod assembly through the linkage mechanism, which serves as a driven component. The specific structure of the linkage mechanism is as follows: it includes a fixed shaft, a sleeve that is rotatable and sleeved on the fixed shaft, and a connecting rod that is arranged on the sleeve and is an integral structure with the sleeve, and a strip hole is arranged along the length direction of the connecting rod; wherein, the two ends of the fixed shaft are respectively connected to the partition and the inner wall of the right end of the box body, and a clearance fit is adopted between the sleeve and the fixed shaft so that the sleeve can better rotate with the fixed shaft as the rotation center.

[0032] The first flip rod assembly and the second flip rod assembly have the same structure, but are arranged in different ways. They are named separately here for the convenience of distinction. The specific structures of the two are as follows:

[0033] The first flip rod assembly includes a first flip rod and a first connecting shaft in an integrated structure, one end face of the first flip rod is connected to the driving shaft, and the first connecting shaft is arranged on the opposite end face of the other end, and the driving shaft is also the fixed rotating end of the first flip rod; the second flip rod assembly includes a second flip rod and a second connecting shaft in an integrated structure, one end face of the second flip rod is connected to the output shaft, and the second connecting shaft is arranged on the opposite end face of the other end, and the output shaft is also the fixed rotating end of the second flip rod; the first flip rod is located in the transmission warehouse, one end of the driving shaft is fixedly connected to it to form an integrated structure, the other end of the driving shaft passes through the partition and can rotate (rotate) relative to the partition, the second connecting shaft is located in the transmission warehouse, one end of the output shaft is fixedly connected to it to form an integrated structure, the other end of the output shaft passes through the right end face of the box body and can rotate (rotate) relative to the box body. In a further preferred scheme, sealing rings can be arranged at the connection positions of the driving shaft and the partition, and the output shaft and the box body to improve the overall sealing performance.

[0034] The linkage mechanism is located between the first flip rod assembly and the second flip rod assembly, and its connection structure with the two is as follows: the first connecting shaft is placed in the strip hole and can move along the strip hole, the second connecting shaft is placed in the strip hole and can move along the strip hole, and the second connecting shaft is arranged opposite to the first connecting shaft. Through the above arrangement, the first flip rod assembly and the second flip rod assembly can be linked through the linkage mechanism. During movement, the second connecting shaft does not contact the first connecting shaft and both move along the strip hole, and the running directions of the two are opposite, that is, the second connecting shaft and the first connecting shaft both move along the strip hole and approach the middle direction of the strip hole at the same time, or move away from the middle direction of the strip hole at the same time.

[0035] In the initial state, the front side of the sampling bucket opening faces upward, the first connecting shaft and the second connecting shaft are both located near the middle of the strip hole and opposite to each other, the driving motor drives the active shaft to rotate, and the first flip rod which is an integral structure with the active shaft rotates, and the first connecting shaft moves along the strip hole in a direction away from the middle of the strip hole. In this process, the connecting rod (sleeve) is driven to rotate, thereby driving the second connecting shaft to move along the strip hole in a direction away from the middle of the strip hole (opposite to the movement direction of the first connecting shaft), and the second connecting shaft drives the second flip rod which is an integral structure with it to rotate, thereby driving the output shaft which is an integral structure with the second flip rod to rotate, and then drives the sampling bucket to rotate through the output shaft to realize the flipping and pouring of water from the sampling bucket.

[0036] The end of the output shaft passes through the right end surface of the box body and is fastened to the sampling barrel. There are various ways to fasten the output shaft and the sampling barrel, for example: a hollow connecting column that is an integral structure with the sampling barrel is provided at the upper end, and pin holes are provided on the hollow connecting column and the output shaft, and the end of the output shaft is inserted into the hollow connecting column and fixed by a pin; technical personnel in this field can also adopt other fastening connection structures, for example: the sampling barrel and the output shaft are fastened by bolts, welding, etc.

[0037] The working principle of the utility model is as follows: after the drone flies to the water collection area with the sampling bucket, the sampling bucket is first filled with water samples, and then the drive motor is controlled to start, and the sampling bucket is controlled to flip through the flip transmission mechanism to pour out the water sample in the bucket, completing a rinse. After 2-3 times, after the sample is rinsed, formal sampling is carried out.

[0038] The above is the preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements without departing from the design principle and technical solution of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
