Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydrology, in particular to a water conservancy and hydrology sediment content detection device. Background Art

[0002] In water conservancy projects, after collecting hydrological water samples from rivers, it is necessary to conduct a sand content inspection and determine the hydrological water quality by measuring the sand content. The sand content refers to the dry sand content in a certain water body. Therefore, during the inspection, the sand in a certain volume of water samples needs to be filtered and then dried. The sand content is determined by measuring the mass of the dried sand.

[0003] In the prior art, when separating water and sand, the sand content detection device usually operates by directly pouring the water into the filter cylinder for filtration. However, during the filtration process, the mud and sand are easily deposited at the bottom of the filter cylinder, thereby clogging the filter cylinder, reducing the speed of subsequent water filtration, thereby reducing the detection efficiency.

[0004] Therefore, we propose a water conservancy and hydrology sediment content detection device to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model utilizes the cooperation of a power structure and a spring to control the reciprocating telescopic movement of two groups of elastic telescopic structures, thereby driving the filter screen cylinder clamped between the two groups of elastic telescopic structures to shake horizontally, so as to maintain the continuous shaking of the filter screen cylinder when filtering water, thereby reducing the situation where mud and sand cover and block the mesh holes, and increasing the filtering speed of the filter screen cylinder on the water body, which is beneficial to improving the detection efficiency.

In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 A water conservancy and hydrological sediment content detection device comprises an outer box body 1 and a filter screen cartridge 2. The filter screen cartridge 2 is clamped inside the outer box body 1 by a pair of elastic telescopic structures. A feed pipe 3 is installed at the top end of the rear side of the outer box body 1. One end of the feed pipe 3 is connected to a metering pump 4, and the other end of the feed pipe 3 extends to the top of the filter screen cartridge 2. The metering pump 4 is externally connected to a water pumping pipe so that a certain amount of water can be drawn into the filter screen cartridge 2 for filtration through the metering pump 4. The elastic telescopic structure comprises a clamping plate 5. A connecting rod 6 is installed on the side of the clamping plate 5 away from the filter screen cartridge 2. The outer box body 1 is close to the connecting rod 6. A support frame 7 is fixed to the inner wall of one side of the rod 6. The support frame 7 is an inverted L-shaped structure. The connecting rod 6 passes through the side plate of the support frame 7. The support frame 7 and the clamping plate 5 are connected by a spring 8, and the connecting rod 6 passes through the inside of the spring 8. A power structure for driving the connecting rod 6 to be ejected is also installed on one of the support frames 7. The power structure is used to drive the connecting rod 6 to be ejected, drive the spring 8 to extend, and the connecting rod 6 retracts and resets under the elastic force of the spring 8, so that the connecting rod 6 drives the clamping plate 5 to move telescopically relative to the support frame 7, so as to drive the filter screen cylinder 2 to shake horizontally and increase the filtration speed.

[0025] See also Figure 4 In order to improve the clamping stability of the filter screen cylinder 2, the structure of the clamping plate 5 is set to be an arc structure that fits the outer circumferential surface of the filter screen cylinder 2, and a positioning rod 51 is connected to the upper surface of the clamping plate 5. The upper edge of the filter screen cylinder 2 protrudes outward to form a flange, and a plurality of positioning holes are provided on the flange. The positioning rod 51 passes through the positioning holes, thereby improving the clamping stability of the filter screen cylinder 2 by the clamping plate 5, and effectively preventing it from falling off during shaking. At the same time, the clamping plate 5 is used to clamp the filter screen cylinder 2, which makes it more convenient to disassemble the filter screen cylinder 2 and weigh the sediment later.

[0026] See also Figure 4 In order to prevent the connecting rod 6 from deflecting during the extension and retraction process, the connecting rod 6 is set to adopt a rectangular structure, and the side plate surface of the support frame 7 is provided with a square through groove matching the connecting rod 6. The rectangular structure cooperates with the rectangular structure to form a limit when the connecting rod 6 moves relative to the support frame 7, thereby preventing the connecting rod 6 from deflecting and causing the filter cylinder 2 to tip over.

[0027] See also Figure 4 In order to facilitate the control of the continuous reciprocating extension and retraction of the connecting rod 6, a power structure is set up including an eccentric wheel 9, a roller 11 and a motor 10, wherein the roller 11 is rotatably connected to the connecting rod 6 through a bracket, the eccentric wheel 9 is rotatably connected to the bottom plate of the support frame 7 through a bracket, and the main part of the motor 10 is fixed to the bracket connected to the eccentric wheel 9, and the output shaft of the motor 10 is coaxially connected to the shaft rod of the eccentric wheel 9 through a coupling, so that the motor 10 can drive the eccentric wheel 9 to rotate. Since the eccentric wheel 9 fits with the roller 11, the eccentric wheel 9 will squeeze the roller 11 during the rotation process, thereby driving the connecting rod 6 to be ejected. In order to improve the transmission stability between the eccentric wheel 9 and the roller 11, convex rings 111 are fixed at both ends of the roller 11, and the convex rings 111 and the eccentric wheel 9 are staggered with each other, so that the eccentric wheel 9 is limited by the convex rings 111 to prevent the eccentric wheel 9 from staggered and escaping from the roller 11, and the transmission stability is higher.
