Description

Technical Field

[0001] This utility model relates to the technical field of turbidity detection equipment, and in particular to an online turbidity meter for use in rivers. Background Technology

[0002] The water quality of a river is related to the quality of life of nearby residents, so it is necessary to monitor the water quality to prevent the health of residents from being affected by factors related to the water quality. When monitoring the water quality of a river, it is necessary to take samples of the water in the river. The existing technology mainly uses online monitoring devices for monitoring.

[0003] Most existing online monitoring devices are fixed in the center of the river, typically using a float floating on the water as an installation platform, with the turbidity detection device directly fixed to the float. However, in practical applications, the water surface is usually not still, and the float will swing on the non-still water surface. The turbidity detection device fixed to the float will swing with the float, resulting in low detection accuracy or even damage to the turbidity detection device.

[0004] Therefore, existing turbidity meters used in rivers have the technical problem of being easily damaged. Summary of the Invention

[0005] This utility model provides an online turbidity meter for rivers, which solves the technical problem that existing turbidity meters for rivers are easily damaged.

[0006] Some implementation schemes for solving the above-mentioned technical problems include:

[0007] An online turbidity meter for a river includes a floating frame assembly that floats in the river. The floating frame assembly is provided with a connecting pipe, which is installed on the floating frame assembly via a universal connector. A counterweight is provided at the lower end of the connecting pipe to keep the connecting pipe in a vertical position.

[0008] The connecting pipe includes an inner cavity, and a water inlet groove is provided on the side wall of the connecting pipe. The water inlet groove communicates with the inner cavity, and river water enters the inner cavity through the water inlet groove.

[0009] The counterweight is equipped with a turbidimeter body, which extends into the inner cavity;

[0010] The universal connector includes a ball fixed to the floating frame assembly, a connecting seat is provided at the upper end of the connecting tube, and the universal connector also includes a connecting groove disposed on the connecting seat and cooperating with the ball, the depth of the connecting groove being greater than the radius of the connecting groove.

[0011] Preferably, the floating frame assembly includes a floating frame, the floating frame being provided with a floating ring, and the floating ring having a hollow structure.

[0012] Preferably, there are at least two float rings, and the at least two float rings are coaxially arranged on the float frame, and the float frame is evenly distributed with through holes to reduce the weight of the float frame.

[0013] Preferably, the center of the sphere is located on the axis of the float.

[0014] Preferably, the sphere and the float are an integral structure, and the sphere is a hollow structure.

[0015] Preferably, the connecting pipe and the connecting seat are an integral structure, the water inlet groove is elongated, and the water inlet groove is arranged along the length direction of the connecting pipe. There are at least two water inlet grooves, and the at least two water inlet grooves are evenly distributed along the circumference of the connecting pipe.

[0016] Preferably, the counterweight is fixed to the connecting pipe by threads, and a connecting ring is provided at the lower end of the connecting pipe. The connecting ring and the connecting pipe are an integral structure. The counterweight includes a counterweight ball, and the counterweight ball is provided with a connecting post. The connecting post and the counterweight ball are an integral structure, and the connecting post extends into the connecting ring.

[0017] Preferably, the connecting ring is provided with a screw, the axis of which is perpendicular to the axis of the connecting ring, the connecting ring is provided with an assembly hole through which the screw passes, and the connecting post is provided with a screw hole that mates with the screw.

[0018] Preferably, the turbidimeter body is mounted on the counterweight via a support rod.

[0019] Preferably, the support rod and the turbidimeter body are an integral structure, the support rod is provided with external threads, the counterweight is provided with internal threads that mate with the external threads of the support rod, and the support rod is also provided with a locking nut that contacts the counterweight.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] By setting up a universal connector and a counterweight, the counterweight keeps the connecting tube vertical under the action of gravity. Since the float frame assembly and the connecting tube are connected by the universal connector, even if the float frame assembly tilts or swings, the connecting tube can remain vertical, thus keeping the turbidity meter body in a relatively static state. This improves the detection accuracy of the turbidity meter body and makes the turbidity meter body less prone to damage.

[0022] By setting a counterweight and placing the turbidity meter body on the counterweight, the counterweight is in a relatively stationary state in the river channel, thus making the turbidity meter body also in a relatively stationary state. The turbidity meter body is not easily damaged, and it has higher accuracy.

[0023] By setting up a connecting pipe with an inlet trough, river water enters the inner cavity through the inlet trough. The turbidity meter body is located inside the inner cavity. The inlet trough can pass through large impurities in the water, thereby preventing large impurities from obscuring the turbidity meter body and further improving the detection accuracy of the turbidity meter body.

[0037] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0038] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0039] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0040] Reference Figures 1 to 6 As shown, an online turbidity meter for a river includes a floating frame assembly 1 that floats in the river. The floating frame assembly 1 is provided with a connecting pipe 2, which is installed on the floating frame assembly 1 via a universal connector 3. A counterweight 4 is provided at the lower end of the connecting pipe 2 to keep the connecting pipe 2 in a vertical state.

[0041] The connecting pipe 2 includes an inner cavity 21, and a water inlet groove 22 is provided on the side wall of the connecting pipe 2. The water inlet groove 22 communicates with the inner cavity 21, and river water enters the inner cavity 21 through the water inlet groove 22.

[0042] The counterweight 4 is equipped with a turbidimeter body 5, which extends into the inner cavity 21.

[0043] The universal connector 3 includes a ball 31 fixed to the floating frame assembly 1, a connecting seat 32 is provided at the upper end of the connecting tube 2, and the universal connector 3 also includes a connecting groove 33 provided in the connecting seat 32 and cooperating with the ball 31, the depth of the connecting groove 33 being greater than the radius of the connecting groove 33.

[0044] Under the influence of gravity, even if the surface of the river water is not static, the turbidity meter body 5 and the counterweight 4 can remain stationary, thereby improving the detection accuracy of the turbidity meter body 5 and making it less prone to damage.

[0045] The turbidimeter and counterweight 4 being in a stationary state means that when the water surface of the river is not stationary, the float frame assembly 1 will swing with the changes in the water surface under the action of buoyancy. The float frame assembly 1 and the connecting pipe 2 are connected by a universal connector 3. The universal connector 3 allows the float frame assembly 1 to swing within a certain range relative to the connecting pipe 2. This swing will not be transmitted to the turbidimeter body 5 and the counterweight 4, thus making the counterweight 4 and the turbidimeter body 5 stationary. This stationary state is relative to the stationary state, that is, relative to the float frame assembly 1.

[0046] During online detection, the turbidimeter body 5 may need to communicate with the host computer via a wired data cable or via a wireless network. Therefore, when the turbidimeter body 5 is in a relatively static state, the communication stability between the turbidimeter body 5 and the host computer is good.

[0047] Meanwhile, the turbidity meter body 5 will not swing with the swing of the float frame assembly 1, thus making the speed at which the river water flows through the turbidity meter stable, thereby improving the detection accuracy of the turbidity meter body 5.

[0048] Since the turbidity meter body 5 does not swing, it is not easy for the turbidity meter body 5 to collide with impurities in the water, thus making the turbidity meter body 5 less prone to damage.

[0049] Reference Figures 1 to 6 As shown, in some embodiments, the floating frame assembly 1 includes a floating frame 11, the floating frame 11 is provided with a floating ring 12, and the floating ring 12 is a hollow structure.

[0050] There are at least two float rings 12, and at least two float rings 12 are coaxially arranged on the float frame 11. The float frame 11 is evenly distributed with through holes 13 to reduce the weight of the float frame 11. The float rings 12 and the float frame 11 can be an integral structure.

[0051] In some embodiments, the center of the sphere 31 is located on the axis of the float 12.

[0052] The sphere 31 and the float 11 are an integral structure, and the sphere 31 is a hollow structure.

[0053] In some embodiments, the connecting pipe 2 and the connecting seat 32 are an integral structure, the water inlet groove 22 is elongated, and the water inlet groove 22 is arranged along the length direction of the connecting pipe 2. There are at least two water inlet grooves 22, and the at least two water inlet grooves 22 are evenly distributed along the circumference of the connecting pipe 2. The connecting seat 32 and the ball 31 can be assembled using a thermal assembly method.

[0054] In some embodiments, the counterweight 4 is fixed to the connecting pipe 2 by threads. The lower end of the connecting pipe 2 is provided with a connecting ring 23. The connecting ring 23 and the connecting pipe 2 are an integral structure. The counterweight 4 includes a counterweight ball 41. The counterweight ball 41 is provided with a connecting post 42. The connecting post 42 and the counterweight ball 41 are an integral structure. The connecting post 42 extends into the connecting ring 23.

[0055] The connecting ring 23 is provided with a screw 231, the axis of which is perpendicular to the axis of the connecting ring 23. The connecting ring 23 has an assembly hole through which the screw 231 passes, and the connecting post 42 has a threaded hole that mates with the screw 231. There may be one or more screws 231. When there are multiple screws 231, all screws 231 are evenly arranged along the circumference of the connecting ring 23.

[0056] Reference Figures 1 to 6 As shown, in some embodiments, the turbidimeter body 5 is mounted on the counterweight 4 via a support rod 51.

[0057] The support rod 51 and the turbidity meter body 5 are an integral structure. The support rod 51 is provided with an external thread, and the counterweight 4 is provided with an internal thread that mates with the external thread of the support rod 51. The support rod 51 is also provided with a locking nut that contacts the counterweight 4.

[0058] The screw 231 allows the height of the turbidity meter body 5 relative to the counterweight 4 to be adjusted, thereby enabling the turbidity meter to have better detection performance.
