Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, and in particular relates to a water level detection device for water conservancy projects. Background Art

[0002] Water conservancy projects often require water level monitoring. Currently, a sounding rod can be used for water level detection. By vertically inserting the sounding rod into the water, the water level at that location can be measured based on the reading of the sounding rod. However, the sounding rod is generally manually operated to detect water. Sometimes, after the sounding rod is inserted into the water, due to visual errors and improper operation, the sounding rod is not perpendicular to the horizontal plane, which will lead to errors in the water level measurement data. When the sounding rod is tilted, the deeper the water level, the greater the error will be. Utility Model Content

[0003] In view of the above problems, the purpose of the present utility model is to provide a water level detection device for water conservancy projects, which solves the problem that a sounding rod can be used for current water level detection. The sounding rod is vertically inserted into the water and the water level at that position is measured according to the reading of the sounding rod. However, the sounding rod is generally manually operated to detect water. Sometimes, after the sounding rod is inserted into the water, due to visual errors and improper operation, the sounding rod is not perpendicular to the horizontal plane, which will cause errors in the water level measurement data. When the sounding rod is tilted, the deeper the water level, the greater the error.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a water level detection device for a water conservancy project, comprising a handle, a bubble level is provided on the upper end of the handle, a connecting tube is provided on the side of the handle, a ring is provided on the end of the connecting tube away from the handle, a sounding rod is slidably inserted into the inner side of the ring, a spring is provided on the inner side of the connecting tube, a pressure block is provided on the side of the spring away from the handle, the pressure block is slidably connected to the connecting tube, a sliding groove is provided on the lower side of the spring of the connecting tube, a sliding rod is slidably provided on the lower side of the sliding groove, the sliding rod passes through the sliding groove and is connected with the pressure block, a push rod is provided on the side of the pressure block away from the spring, a rubber head is provided on the side of the push rod away from the pressure block, the rubber head passes through the ring and contacts the outer side surface of the sounding rod.

[0005] The beneficial effects of the present invention are as follows: holding the handle, inserting the sounding rod from the inner side of the collar, extending the lower end of the sounding rod into the water bottom, making the bubble level vertically upward, observing the bubble level, when the bubble in the bubble level is at the upper center position, it means that the bubble level is in a horizontal state, which means that the sounding rod is in a horizontal state, thereby effectively avoiding problems such as visual errors and improper operation, which lead to the sounding rod being not perpendicular to the horizontal plane, and avoiding errors in water level measurement data.

[0006] In order to facilitate the marking of water level data;

[0007] As a further improvement of the above technical solution: a connecting rod is provided on the lower side of the handle, an indicator rod is provided at the lower end of the connecting rod, and an end of the indicator rod away from the connecting rod is close to the depth measuring rod.

[0008] The beneficial effect of this improvement is that when the connecting rod and the indicator rod are set, it is sometimes difficult to observe the surface scale of the sounding rod when measuring the water level. At this time, by pulling the sliding rod, the position of the ring relative to the sounding rod is adjusted in the same way as the above process, so that the indicator rod just touches the horizontal plane. At this time, the scale data of the sounding rod corresponding to the indicator rod is the water level depth, which is convenient for marking the water level data. The sounding rod can be directly pulled out to observe and record the scale data marked on the indicator rod.

[0009] In order to change the overall length of the sounding rod;

[0010] As a further improvement of the above technical solution: the sounding rod includes a top rod, an extension rod and a bottom rod, the top rod, the extension rod and the bottom rod are all threadedly connected, and the extension rods are threadedly connected to each other.

[0011] The beneficial effects of this improvement are: the sounding rod consists of a top rod, an extension rod and a bottom rod. The overall length of the sounding rod can be changed by increasing or decreasing the number of extension rods, which is suitable for measuring different water levels. In addition, the sounding rod can be disassembled and assembled through threaded connections, which is easy to carry.

[0012] In order to reduce the weight of the sounding rod;

[0013] As a further improvement of the above technical solution: the top rod, the extension rod and the bottom rod are all hollow rods.

[0014] The beneficial effect of this improvement is that the top rod, the extension rod and the bottom rod are all hollow rods, which reduces the weight of the sounding rod.

[0015] In order to facilitate operation, the sounding rod is relatively vertically sunk;

[0016] As a further improvement of the above technical solution: the inner side of the bottom rod is filled with weight blocks.

[0017] The beneficial effect of this improvement is that the inner side of the bottom rod is filled with weight blocks to increase the weight of the bottom rod. Combined with the top rod and the extension rod being hollow rods, the bottom rod will be significantly heavier when sunk into the water, making it easier to operate the depth rod to sink relatively vertically.

[0018] In order to prevent the bottom rod from sinking directly into the mud;

[0019] As a further improvement of the above technical solution: the lower side thread of the bottom rod is provided with a flat mesh plate.

[0020] The beneficial effects of this improvement are: a flat mesh plate is provided on the lower side thread of the bottom rod, which can increase the contact area with the silt when the bottom rod sinks to the bottom of the water, thereby preventing the bottom rod from sinking directly into the silt too deep, resulting in obvious errors in the measurement data, and the flat mesh plate is set as a mesh plate, which can reduce the water resistance when sinking.

[0021] To increase the limit of the top of the sounding rod relative to the collar;

[0022] As a further improvement of the above technical solution: the upper end thread of the push rod is provided with a blocking piece, and the diameter of the blocking piece is larger than the inner diameter of the collar.

[0023] The beneficial effect of this improvement is that a baffle is provided on the upper thread of the push rod, which can increase the restriction of the top end of the sounding rod relative to the collar, and avoid the sounding rod sliding directly out from the bottom side of the collar when measuring the water level due to improper operation.

[0024] In order to facilitate the change of the position of the indicator rod;

[0025] As a further improvement of the above technical solution: the connecting rod is slidably plugged into the handle, and the side thread of the handle is provided with a locking knob, and the locking knob thread passes through the handle and contacts the outer side surface of the connecting rod.

[0026] The beneficial effect of this improvement is that the locking knob thread is set to pass through the handle and contact the outer side of the connecting rod, which makes it easy to adjust the downward extension length of the connecting rod, thereby facilitating the change of the position of the indicator rod according to measurement needs, and facilitating the adjustment of the indicator rod to a horizontal position while keeping the ring stable.

[0027] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
