Description

Technical Field

[0001] The utility model relates to the technical field of water level measurement; more specifically, it relates to a portable water level measurement device. Background Art

[0002] The field measurement of water levels in rivers, lakes, etc. is closely related to human social life and production. The planning, design, construction, and management of water conservancy projects require water level data; the construction of projects such as bridges, ports, waterways, water supply and drainage also requires water level data; in flood control and drought relief, water level data is even more important, which is the basis for hydrological forecasting and hydrological information. At this time, it is necessary to measure the water level.

[0003] Currently, in the process of using the existing portable water level measurement devices, since the existing water level measurement devices generally wind the connecting wires on the wire winding rollers, but most of them do not have the function of binding the connecting wires, which may cause the connecting wires to be relatively loose and not convenient for placement, reducing the practicability of the device to a certain extent. Moreover, the existing water level measurement devices need to put the sensors and the connecting wires into the water for measurement. After the measurement is completed, there will be residual moisture on the connecting wires, and the moisture may cause dust to adhere to the connecting wires, and the surface of the connecting wires may be covered with sludge later, which is not convenient for the subsequent use of the connecting wires, reducing the practicability of the device to a certain extent. Therefore, there is an urgent need for a portable water level measurement device to solve the above problems. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a portable water level measurement device to solve the problems existing in the above background art.

[0005] The utility model provides the following technical solution: A portable water level measurement device, comprising:

[0006] A moving bottom plate, threaded rods are connected to the inside of the four corners of the moving bottom plate. The upper end surface of one side of the moving bottom plate is fixedly connected with a first support plate, and a cleaning structure is arranged at the middle position of the inner surface of the first support plate. The upper end surface of the other side of the moving bottom plate is fixedly connected with a second support plate, and one side of the upper end surface of the second support plate is fixedly connected with a mounting plate, and one end of the mounting plate is fixedly connected with the inner surface of the upper end of the first support plate. A measuring instrument is installed on the upper end surface of the mounting plate, and a connecting wire is communicated with the lower end surface of the measuring instrument, and one end of the connecting wire is communicated with a water level probe. A second lead screw is rotatably connected to the middle position of the inner surface of the second support plate, positioning plates are sleeved on the outer surfaces of both ends of the second lead screw, and a wire winding roller is fixedly connected to the middle position of the inner surface of the second support plate;

[0007] The cleaning structure includes a first lead screw, and the first lead screw is connected to the inside of the middle position of the inner surface of the first support plate by bearings.

[0008] Preferably, the cleaning structure further includes a moving frame, and there are two sets of moving frames. The two sets of moving frames are respectively sleeved on the outer surfaces of both ends of the first lead screw, and the two sets of moving frames are opposite to each other. And the threads of the parts of the two sets of moving frames sleeved on the outer surfaces of both ends of the first lead screw are opposite to each other. A cleaning cylinder is inserted into the moving frame, and cleaning cotton is arranged on the inner wall surface of the cleaning cylinder. And the inner wall surface of the cleaning cotton is attached to the outer surface of the connecting wire. A supporting plate is attached to the bottom surfaces of the moving frame and the cleaning cylinder. Fixed rods are fixedly connected to the inside of both ends of the upper end surface of the supporting plate. Springs and fixing blocks are sleeved on the outer surfaces of the fixed rods. And the upper end surface of the fixing block is fixedly connected to the bottom surface of the moving frame. This design can drive the two sets of moving frames to move outward or inward synchronously on the outer surfaces of both ends of the first lead screw when the first lead screw rotates. Thus, through this design, it is convenient to make the two sets of cleaning cotton sleeved on the outer surface of the connecting wire.

[0009] Preferably, rectangular insertion grooves are formed on the inner wall surface of the moving frame. A rectangular insertion plate is arranged on the outer surface of the cleaning cylinder. And the internal dimensions of the rectangular insertion groove are adapted to the external dimensions of the rectangular insertion plate. There are two sets of the rectangular insertion plates and the rectangular insertion grooves. And the positions of the two sets of rectangular insertion plates and rectangular insertion grooves correspond to each other. This design enables the connection between the moving frame and the cleaning cylinder to be more stable. And the two sets of rectangular insertion plates and rectangular insertion grooves that are mutually misaligned and corresponding prevent the cleaning cylinder from detaching from the inside of the moving frame.

[0010] Preferably, a U-shaped groove is formed in the inside of the outer surface of one side of the mounting plate, and a connecting wire is inserted into the U-shaped groove. This design, when the measuring instrument is installed on the upper end surface of the mounting plate, enables the connecting wire to be placed inside the U-shaped groove, facilitating the use of the device.

[0011] Preferably, the internal threads of the parts of the two sets of positioning plates sleeved on the outer surface of the second lead screw are opposite to each other. And receiving grooves are formed on the upper end surface of the moving bottom plate and the bottom surface of the mounting plate. And the internal dimensions of the receiving grooves are the same as the external dimensions of the positioning plates. This design can drive the two sets of positioning plates to move outward or inward synchronously on the outer surfaces of both ends of the second lead screw when the second lead screw rotates. Thus, it is convenient to limit the connecting wire through the positioning plates and prevent the connecting wire from becoming scattered after being wound.

[0012] Preferably, there are two sets of the winding rollers, and the positions of the two sets of winding rollers correspond to each other. A limiting plate is arranged on the outer surface of one end of the winding roller. This design enables the connecting wire to be wound on the outer surfaces of the two sets of winding rollers, and the design of the limiting plate avoids the situation that the connecting wire detaches from the outer surface of the winding roller.

[0013] The technical effects and advantages of the present utility model: By rotating the second lead screw, the two positioning plates can be driven to move synchronously outward or inward on the outer surface of the second lead screw. When the connecting wire is wound on the outer surface of the winding roller, the outer surface of the positioning plate can be made to fit the outer surface of the connecting wire, thereby avoiding the situation that the connecting wire is scattered and not convenient to place, and improving the practicality of the device to a certain extent;

[0014] By pulling the connecting wire, the outer surface of the connecting wire passes through the middle position between the two cleaning cottons. Thus, the cleaning cottons absorb the residual moisture on the outer surface of the connecting wire, avoiding the situation that dust adheres to the outer surface of the subsequent connecting wire and affects its use, improving the practicality of the device to a certain extent. Moreover, its overall structure is simply and reasonably designed, with high practicality and is easy to be popularized and applied. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. In addition, the forms of each structure described in the following embodiments are merely examples, and the water level measurement related to the present utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0022] Embodiment 1

[0023] As Figure 1 - Figure 2 shown, this embodiment proposes a portable water level measurement device, including:

[0024] A moving bottom plate 1, threaded rods 2 are internally threaded at the four corners of the moving bottom plate 1, and universal wheels are installed on the bottom surfaces at the four corners of the moving bottom plate 1. This design enables the device to be pushed through the universal wheels for movement. And when the device moves to a suitable position, the four groups of threaded rods 2 can be rotated so that the bottom surfaces of the threaded rods 2 abut against the ground, thereby positioning the device;

[0025] One side of the upper end surface of the moving bottom plate 1 is fixedly connected to a first support plate 3, and a cleaning structure 4 is arranged at the middle position of the inner surface of the first support plate 3. The other side of the upper end surface of the moving bottom plate 1 is fixedly connected to a second support plate 5, and one side of the upper end surface of the second support plate 5 is fixedly connected to a mounting plate 6. And one end of the mounting plate 6 is fixedly connected to the inner surface of the upper end of the first support plate 3. A measuring instrument 7 is installed on the upper end surface of the mounting plate 6, and a connecting wire 8 is communicated with the lower end surface of the measuring instrument 7. And one end of the connecting wire 8 is communicated with a water level probe 9. A U-shaped groove is formed inside the outer surface of one side of the mounting plate 6, and the connecting wire 8 is inserted into the U-shaped groove. When the measuring instrument 7 is installed on the upper end surface of the mounting plate 6, the connecting wire 8 communicated with the lower end surface of the measuring instrument 7 can be inserted into the U-shaped groove, thus facilitating the use and placement of the connecting wire 8;

[0026] At the middle position of the inner surface of the second support plate 5, a second lead screw 10 is connected by bearings. On the outer surfaces of both ends of the second lead screw 10, positioning plates 11 are sleeved. And at the middle position of the inner surface of the second support plate 5, a wire winding roller 12 is fixedly connected. The internal threads of the parts of the two positioning plates 11 sleeved on the outer surface of the second lead screw 10 are opposite to each other. And on the upper end surface of the moving bottom plate 1 and the bottom surface of the mounting plate 6, storage grooves are opened. And the internal dimensions of the storage grooves are the same as the external dimensions of the positioning plates 11. There are two wire winding rollers 12, and the positions of the two wire winding rollers 12 correspond to each other. And on the outer surface of one end of the wire winding roller 12, a limiting plate is arranged. This design enables the connecting wire 8 to be wound on the outer surface of the wire winding roller 12, and the limiting plate can prevent the connecting wire 8 from detaching from the outer surface of the wire winding roller 12. And in this design, when the second lead screw 10 is rotated clockwise, the two positioning plates 11 can move inwards on the outer surfaces of both ends of the second lead screw 10 synchronously. Thus, the surfaces of the two positioning plates 11 close to each other are pressed against the outer surface of the connecting wire 8, so as to prevent the connecting wire 8 from becoming scattered after winding. When the second lead screw 10 is rotated counterclockwise, the two positioning plates 11 can move outwards on the outer surfaces of both ends of the second lead screw 10 synchronously. Thus, the two positioning plates 11 can be respectively received in the storage grooves opened on the upper end surface of the moving bottom plate 1 and the bottom surface of the mounting plate 6. At this time, the connecting wire 8 can be taken out for use.

[0027] Embodiment 2

[0028] As Figure 3 - Figure 5 shown, based on the same concept as the above embodiment, this embodiment also proposes:

[0029] The cleaning structure 4 includes a first lead screw 41, and the first lead screw 41 is connected by bearings inside the middle position of the inner surface of the first support plate 3. The cleaning structure 4 also includes a moving frame 42, and there are two moving frames 42. The two moving frames 42 are respectively sleeved on the outer surfaces of both ends of the first lead screw 41, and the two moving frames 42 are opposite to each other. And the threads of the parts of the two moving frames 42 sleeved on the outer surfaces of both ends of the first lead screw 41 are opposite to each other. This design can drive the two moving frames 42 to move inwards synchronously on the outer surfaces of both ends of the first lead screw 41 when the first lead screw 41 is rotated clockwise. Thus, the outer surface of the connecting wire 8 can be covered by the two cleaning cotton 44. When the first lead screw 41 is rotated counterclockwise, it can drive the two moving frames 42 to move outwards synchronously on the outer surfaces of both ends of the first lead screw 41. At this time, the connecting wire 8 can be taken out from between the two cleaning cotton 44;

[0030] The inside of the moving frame 42 is inserted with a cleaning cylinder 43, and a cleaning cotton 44 is arranged on the inner wall surface of the cleaning cylinder 43. The inner wall surface of the cleaning cotton 44 is attached to the outer surface of the connecting wire 8. A supporting plate 45 is attached to the bottom surfaces of the moving frame 42 and the cleaning cylinder 43. Fixed rods 46 are fixedly connected to the inner parts of both ends of the upper end surface of the supporting plate 45. Springs 47 and fixing blocks 48 are sleeved on the outer surfaces of the fixed rods 46. The upper end surface of the fixing block 48 is fixedly connected to the bottom surface of the moving frame 42. This design can push the supporting plate 45 to move. While the supporting plate 45 is moving, the fixed rod 46 can move at the middle position of the fixing block 48. At this time, the cleaning cylinder 43 can be taken out of the moving frame 42 and the cleaning cylinder 43 and the cleaning cotton 44 can be replaced. At the same time, the self-elasticity of the spring 47 can make the supporting plate 45 reset itself;

[0031] Rectangular insertion grooves are formed on the inner wall surface of the moving frame 42. Rectangular insertion plates are arranged on the outer surface of the cleaning cylinder 43. The internal dimensions of the rectangular insertion grooves are adapted to the external dimensions of the rectangular insertion plates. There are two groups of rectangular insertion plates and rectangular insertion grooves, and the positions of the two groups of rectangular insertion plates and rectangular insertion grooves correspond to each other. This design enables the cleaning cylinder 43 to be inserted into the rectangular insertion grooves through the rectangular insertion plates, thereby completing the connection between the moving frame 42 and the cleaning cylinder 43. Through the design of two groups of mutually corresponding and offset rectangular insertion grooves and rectangular insertion plates, they can restrict each other, thus preventing the cleaning cylinder 43 from detaching from the inside of the moving frame 42 during use.

[0032] Working principle: When the device is in use, first push the device to a suitable position, and then rotate the threaded rod 2 inside the moving bottom plate 1 so that the bottom surface of the threaded rod 2 abuts against the ground, thereby positioning the device. Subsequently, when the second lead screw 10 is rotated counterclockwise, the two positioning plates 11 can move outward synchronously on the outer surfaces at both ends of the second lead screw 10. At this time, the connecting wire 8 can be manually removed from the outer surface of the wire winding roller 12, and the water level probe 9 can be put into the water for measurement, and the output data can be analyzed by the measuring instrument 7;

[0033] After the measurement is completed, place the outer surface of the connecting wire 8 at the middle position between the two sets of moving frames 42. Then, rotate the first lead screw 41 clockwise to make the two sets of moving frames 42 move inward synchronously, and make the outer surfaces of the two sets of cleaning cotton 44 fit on the outer surface of the connecting wire 8. Next, manually pull the connecting wire 8 upward so that the outer surface of the connecting wire 8 moves between the two sets of cleaning cotton 44, and the cleaning cotton 44 absorbs the moisture on the outer surface of the connecting wire 8. Thus, to a certain extent, the situation that dust adheres to the outer surface of the connecting wire 8 is avoided through the cleaning structure 4. When the connecting wire 8 is taken out of the water, rotate the first lead screw 41 in the reverse direction to make the two sets of moving frames 42 move outward synchronously. At this time, the connecting wire 8 can be separated from the middle position between the two sets of moving frames 42, and it can be re-wound on the outer surface of the winding roller 12. Then, rotate the second lead screw 10 in the reverse direction to make the surfaces of the two sets of positioning plates 11 fit on the outer surface of the connecting wire 8, thereby avoiding the situation that the connecting wire 8 becomes scattered;

[0034] When the equipment is used up, the supporting plate 45 can be pushed. At the same time, the fixing rod 46 moves inside the fixing block 48, so that the upper surface of the supporting plate 45 no longer fits on the bottom surface of the cleaning cylinder 43. At this time, the cleaning cylinder 43 and the cleaning cotton 44 can be replaced. At the same time, due to the self-elasticity of the spring 47, the supporting plate 45 can reset itself, so that the supporting plate 45 fits on the bottom surface of the cleaning cylinder 43 again. The above is the entire working principle of this utility model.

[0035] Finally, several points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense.

Other structures can refer to the usual designs. Without conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;
