[0001] The present invention relates to the field of detection devices, and in particular to a sludge thickness detection device and a use method thereof. Background Art

[0002] As we all know, hydropower stations are generally equipped with maintenance water collection wells and leakage water collection wells, or the two are combined into one water collection well, and each water collection well is equipped with a drainage pump. During the long-term operation of the water collection well, the sediment will gradually settle at the bottom of the well and accumulate into silt. If the sediment content in the water collection well is high, the water collection well needs to be inspected and desilted. In practical applications, cleaning the silt in the water collection well is an important task to ensure the normal operation of the sewage treatment tank. Before cleaning, the silt thickness in the water collection well needs to be measured by a silt thickness detection device. However, when the existing silt thickness detection device is used, the silt thickness detected by it is not accurate enough, and the detection effect does not meet expectations. Summary of the invention

[0005] Furthermore, in the sludge thickness detection device described in the present invention, the support assembly includes a support platform, a screw and a drive motor. A rail groove is provided on the support platform. The screw is rotatably arranged in the rail groove around its own rod axis. The drive motor is arranged on the support platform, and the output shaft of the drive motor is transmission-connected to one end of the screw.

[0006] Furthermore, in the sludge thickness detection device described in the present invention, a threaded hole is provided on the movable plate, and the movable plate is threadedly connected to the screw rod through the threaded hole.

[0007] Furthermore, in the sludge thickness detection device described in the present invention, a limit stopper is provided on the movable plate, and the measuring rod is detachably arranged in the limit stopper.

[0008] Furthermore, in the sludge thickness detection device described in the present invention, the measuring component also includes a telescopic rod, the telescopic rod is provided with a measuring scale line, the ruler rod is provided with a receiving groove opening upward, and the telescopic rod is slidably arranged in the receiving groove along a first direction.

[0009] Furthermore, in the sludge thickness detection device described in the present invention, the measuring component also includes a protective shell, the protective shell is arranged at the top end of the telescopic rod in the first direction, an elastic buckle is provided on the protective shell, and an embedding hole for embedding the elastic buckle is opened on the ruler slot rod.

[0010] Furthermore, in the sludge thickness detection device described in the present invention, the telescopic rod includes a plurality of connecting rods which are sleeved in sequence.

[0011] Furthermore, in the sludge thickness detection device described in the present invention, the measuring component includes a reference plate connected to the ruler slot rod, and the reference plate is provided with a limit hole.

[0012] Accordingly, another object of the present invention is to provide a method for using a sludge thickness detection device, which is applied to the sludge thickness detection device as described above, and comprises the following steps: S1: moving the support assembly to control the target marking line on the casing to remain level with the water surface; S2: Obtaining the water depth from the probe to the surface of the mud layer through the probe and the ultrasonic mud level meter; S3: obtaining the distance from the water surface to the bottom of the silt layer and the first silt thickness through the measuring rod and the measuring assembly; S4: determining a second silt thickness based on the length indicated by the target marking line, the distance from the water surface to the bottom of the silt layer, and the water depth; S5: Determine the actual sludge thickness based on the first sludge thickness and the first sludge thickness.

[0013] Furthermore, in the method for using the sludge thickness detection device of the present invention, step S3 includes the following steps: Driving the measuring rod to move along a first direction relative to the movable plate until the bottom end of the measuring rod along the first direction is inserted into the bottom surface of the silt layer, so as to form a silt mark and a water surface mark on the measuring rod; Taking the measuring rod out of the sludge layer and placing the measuring rod on a reference plate; The height of the silt mark and the height of the water surface mark are determined by the groove rod.

The height of the silt mark is the first silt thickness of the silt layer, and the height of the water surface mark is the distance from the water surface to the bottom of the silt layer.

[0015] After that, ultrasonic detection can be performed. Specifically, since the detection assembly includes a movable plate, a casing and a probe, the movable plate can be movably arranged on the support assembly. In actual use, the movable plate can be moved up and down relative to the support assembly, thereby driving the casing and the probe to move up and down, and controlling a certain marking scale line on the casing to be level with the water surface, so that the probe on the detection assembly can be extended into the predetermined depth below the water surface of the water collection well of the hydropower station. After that, the corresponding detection is performed through the probe and the ultrasonic mud leveler. Specifically, the probe emits ultrasonic sound to detect the test area, and the detection result is transmitted to the ultrasonic mud leveler by the connecting line, which can measure the distance between the probe and the surface of the silt layer. When performing ultrasonic detection, the height of the water surface mark detected by the above-mentioned artificial detection and the length indicated by the target marking line can be input into the control panel. Based on the distance between the probe and the surface of the silt layer and the height of the water surface mark, the control panel can obtain the second silt thickness of the silt layer, which is equal to the height of the water surface mark-the length indicated by the target marking line-the distance between the probe and the surface of the silt layer.

[0016] On this basis, the actual silt thickness can be determined based on the first silt thickness and the second silt thickness, such as taking the average of the first silt thickness and the second silt thickness to obtain the actual silt thickness of the silt layer. In summary, the water well silt thickness detection device of the present invention has a manual detection function and an ultrasonic detection function, which can obtain the silt layer thickness of the area to be detected based on the dual operation of manual detection and ultrasonic detection, thereby improving the accuracy and precision of the detected silt layer thickness.

[0019] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0020] Please refer to Figure 1 as well as Figure 2 The present invention discloses a sludge thickness detection device, which includes a support component 1, a measuring component 2, an ultrasonic mud level sensor 3, a detection component 5, a control panel 4 and a measuring rod 6, wherein: The ultrasonic mud level sensor 3 and the control panel 4 are both arranged on the outer side wall of the support assembly 1, and the ultrasonic mud level sensor 3 is in communication connection with the control panel 4; The detection assembly 5 includes a movable plate 51, a sleeve 53 and a probe 54, wherein the movable plate is movably arranged on the support assembly; the measuring rod 6 is movably arranged on the movable plate along a first direction, the sleeve 53 is arranged on the movable plate 51, and a marking scale line is arranged on the outer peripheral surface of the sleeve 53; the probe 54 is arranged at the bottom end of the sleeve 53 in the first direction, and the probe 54 is electrically connected to the ultrasonic mud level sensor 3; wherein the first direction is a vertical height direction; The measuring assembly 2 comprises a ruler slot rod 21, which is arranged on the outer wall of the supporting assembly 1 and has measuring scale lines on it; the measuring rod 6 is movably arranged on the movable plate 51. The marking scale lines and the measuring scale lines both extend along the first direction.

[0021] From the above description, it can be seen that the beneficial effect of the present invention is that the silt thickness detection device in the present invention has both manual detection function and ultrasonic detection function. First, manual detection can be performed first, specifically: the measuring rod is directly inserted into the silt layer in the area to be measured (such as the water collection well of a hydropower station) through the limit bayonet 52 on the movable plate 51, until the bottom end of the measuring rod reaches the bottom of the silt layer, at which time, a silt mark and a water surface mark can be formed on the measuring rod. Afterwards, the measuring rod is taken out and placed on the side of the ruler groove rod 21. Since the ruler groove rod 21 is provided with a measuring scale line, the height of the silt mark and the water surface mark on the measuring rod can be measured according to the measuring scale line. The height of the silt mark is the first silt thickness of the silt layer (the thickness of the silt layer measured manually), and the height of the water surface mark is the distance from the water surface to the bottom of the silt layer.

[0022] Afterwards, ultrasonic testing can be performed, which can be measured based on the ultrasonic mud level device 3 and the probe 54. Specifically, since the detection component 5 includes a movable plate 51, a sleeve 53 and a probe 54, the movable plate 51 is movably arranged on the support component 1 along the first direction. In actual use, the movable plate 51 can slide up and down relative to the support component 1, thereby driving the sleeve 53 and the probe 54 to move up and down, so that the probe 54 on the detection component 5 can be extended into the predetermined depth below the water surface of the water collection well of the hydropower station. Afterwards, corresponding detection is performed through the probe 54 and the ultrasonic mud level device 3. Specifically, the probe 54 is used to detect the area to be tested, and the detection result is transmitted to the ultrasonic mud level device 3 by the connecting line for display, thereby completing the detection operation of the water depth from the probe 54 to the surface of the silt layer, which can measure the distance between the probe 54 and the surface of the silt layer (i.e., the interface between the silt layer and the water). When conducting ultrasonic detection, the height of the water surface mark detected manually can be input into the control panel. Based on the acquired distance between the probe and the surface of the silt layer and the height of the water surface mark, the control panel can obtain a second silt thickness of the silt layer. The second silt thickness is equal to the height of the water surface mark - the length indicated by the marking scale line - the distance between the probe 54 and the surface of the silt layer.

[0023] On this basis, the actual silt thickness can be determined based on the first silt thickness and the second silt thickness, such as taking the average of the first silt thickness and the second silt thickness to obtain the actual silt thickness of the silt layer. The water well silt thickness detection device of the present invention has a manual detection function and an ultrasonic detection function, which can obtain the silt layer thickness of the area to be detected based on the dual operation of manual detection and ultrasonic detection, thereby improving the accuracy and precision of the detected silt layer thickness.

[0024] Furthermore, in the sludge thickness detection device described in the present invention, the support assembly 1 includes a support platform 11, a screw 13 and a drive motor 14. A rail groove 12 is opened on the support platform 11. The screw is rotatably arranged in the rail groove around its own rod axis. The drive motor 14 is arranged on the support platform 11, and the output shaft of the drive motor 14 is connected to the screw 13.

[0025] Furthermore, in the sludge thickness detection device described in the present invention, a threaded hole is provided on the movable plate 51, and the movable plate 51 is threadedly connected to the screw rod 13 through the threaded hole.

[0026] As can be seen from the above description, the screw 13 is connected to the output shaft of the driving motor 14, and the screw 13 is synchronously rotated around its axis by the rotation of the output shaft of the driving motor 14. While the screw 13 rotates, the movable plate 51 threadedly connected to the screw 13 will be lifted up and down, so that the probe 54 at the bottom of the movable plate 51 can be easily extended into the water collection well, so that one of the marking scale lines on the casing 53 (such as the 6cm scale line, the 7cm scale line) is kept level with the actual water surface, so that the thickness of the silt layer in the water collection well can be effectively detected.

[0027] Furthermore, in the sludge thickness detection device described in the present invention, the measuring component 2 includes a reference plate 22 connected to the ruler-groove rod 21 , and a limiting hole 23 is provided on the reference plate 22 .

[0028] From the above description, it can be seen that after the measuring rod is directly embedded in the silt of the hydropower station's collection well, the measuring rod is taken out and placed in the limiting hole 23 on the reference plate 22 to provide limiting support for the measuring rod, thereby facilitating the measurement of the silt mark and water surface mark on the measuring rod.

[0029] Furthermore, in the sludge thickness detection device described in the present invention, the measuring component 2 also includes a telescopic rod 24, the telescopic rod 24 is provided with a measuring scale line, the ruler rod 21 is provided with a receiving groove, and the telescopic rod 24 is slidably arranged in the receiving groove along the first direction.

[0030] As can be seen from the above description, the telescopic rod 24 has a stretched state and a compressed state. When in the stretched state, the telescopic rod 24 extends out of the accommodating cavity from the notch of the accommodating cavity, and when in the compressed state, the telescopic rod 24 is located in the accommodating cavity. In practical applications, since the telescopic rod 24 and the ruler slot rod 21 can slide relative to each other, when manually measuring, the stretching length can be adjusted according to the height of the long rod silt mark or the water surface mark, that is, the telescopic rod 24 can be pulled out of the accommodating cavity to extend the measurable length, which is more convenient, thereby reducing the length setting of the ruler slot rod, thereby reducing the overall volume of the silt thickness detection device, and facilitating use.

[0031] Furthermore, in the sludge thickness detection device described in the present invention, the measuring component 2 also includes a protective shell 25, the protective shell 25 is arranged at the top end of the telescopic rod 24 in the first direction, the protective shell 25 is provided with an elastic buckle 26, and the ruler groove rod 21 is provided with an embedding hole 27 for embedding the elastic buckle 26.

[0032] As can be seen from the above description, a protective shell 25 is provided at the top of the telescopic rod 24 to protect the top of the telescopic rod 24. When the telescopic rod 24 is in a retracted state, that is, when the telescopic rod 24 is stored in the accommodating cavity in the ruler slot rod 21, the elastic buckle 26 is embedded in the embedding hole 27 on the ruler slot rod 21, so that the telescopic rod 24 can be protected and limited in the accommodating cavity to prevent it from sliding out.

[0033] Furthermore, in the sludge thickness detection device described in the present invention, the telescopic rod 24 includes a plurality of connecting rods which are sleeved in sequence, and two adjacent connecting rods can be relatively telescopic.

[0034] From the above description, it can be seen that the telescopic rod 24 includes a plurality of connecting rods, and the plurality of connecting rods can be relatively retracted, so that when in use, the telescopic rod 24 can be stretched according to the height of the silt mark and the water surface mark on the measuring rod to extend the length, which is convenient for measurement when the silt size is thicker or the water depth is deeper.

[0035] Furthermore, in the sludge thickness detection device described in the present invention, a limit stopper 52 is provided on the movable plate 51 , and the measuring rod is detachably arranged in the limit stopper 52 .

[0036] It should be noted that the existing sludge thickness detection device requires the detection personnel to hold the measuring rod for a long time when in use, which can easily make the detection personnel's arms tired, thereby causing errors and affecting subsequent detection. Moreover, when in use, it is impossible to ensure that the measuring rod is vertically inserted into the sludge layer, which will affect the final detection result of the sludge thickness detection device.

[0037] To this end, in the sludge thickness detection device of the present invention, a limit bayonet 52 is provided on the movable plate 51, and the limit bayonet 52 can be used to place a measuring rod. The limit bayonet 52 can be used to limit and support the measuring rod, so that the detection personnel do not need to hold the measuring rod for a long time, thereby improving the use experience of the detection personnel. Moreover, the limit bayonet 52 is used to limit and support the measuring rod. When it is used, it can be moved vertically downward along the groove of the limit bayonet 52, thereby improving the accuracy of the downward movement of the measuring rod.

[0038] Accordingly, another object of the present invention is to provide a method for using a sludge thickness detection device, which is applied to the sludge thickness detection device as described above, such as Figure 5 As shown, it includes the following steps: S1: moving the support assembly 1 to control the target marking line on the casing 53 to remain level with the water surface; S2: Obtaining the water depth from the probe 54 to the surface of the silt layer through the probe 54 and the ultrasonic mud level sensor 3; S3: Obtaining the distance from the water surface to the bottom of the silt layer and the first silt thickness through the measuring rod and the measuring component 2; S4: determining a second silt thickness based on the length indicated by the target marking line, the distance from the water surface to the bottom of the silt layer, and the water depth; S5: Determine the actual sludge thickness based on the first sludge thickness and the first sludge thickness.

[0039] The length indicated by the target marking line (denoted as L2) is the depth of the probe 54 entering below the water surface. The length can be selected according to the actual situation, and can be any value of 5-10 cm. Within this value range, the probe 54 (i.e., the sensor) can be used normally. In actual use, the sleeve 53 is provided with marking scale lines, and the target marking line is a marking line in the marking scale lines (such as a 6 cm scale line, a 7 cm scale line). By controlling the target marking line to be level with the actual water surface, it is ensured that the depth of the probe 54 entering below the water surface reaches a fixed depth, thereby ensuring the normal and effective use of the probe 54.

[0040] The ultrasonic mud level meter 3 is an instrument specially used to measure the interface position between sludge, waste and liquid. The probe 54 is used in conjunction with the ultrasonic mud level meter 3, which is responsible for transmitting and receiving ultrasonic signals to measure corresponding data. In practical applications, the probe 54 can transmit ultrasonic waves into the water collection well of the hydropower station. The emitted ultrasonic waves will be reflected when encountering the silt layer. By measuring the time between the transmitted wave and the reflected wave, the water depth L1 from the probe 54 to the surface of the silt layer can be obtained. The water depth L1 from the probe 54 to the surface of the silt layer + the length L2 indicated by the target marking line = the distance L3 from the water surface to the surface of the silt layer.

[0041] Afterwards, the inspector can insert the measuring rod into the silt layer so that the bottom of the measuring rod is inserted into the bottom surface of the silt layer. Afterwards, the measuring rod is pulled out of the silt layer and placed on the limit hole 23 of the reference plate 22, and the distance L from the water surface to the bottom surface of the silt layer and the first silt thickness D1 can be obtained by measuring with the ruler groove rod 21 and the telescopic rod 24.

[0042] On this basis, the second silt thickness can be determined based on the length indicated by the target marking line, the distance L from the water surface to the bottom of the silt layer, and the water depth L1. Since the distance L3 from the water surface to the surface of the silt layer = the water depth L1 from the probe 54 to the surface of the silt layer + the length L2 indicated by the target marking line, the second silt thickness D2 = the distance L from the water surface to the bottom of the silt layer - the distance L3 from the water surface to the surface of the silt layer = the distance L from the water surface to the bottom of the silt layer - the water depth L1 from the probe 54 to the surface of the silt layer - the length L2 indicated by the marking scale line. In actual applications, the distance L from the water surface to the bottom of the silt layer and the length L2 indicated by the target marking line can be input into the control panel 4, and the actual silt thickness of the silt layer can be determined by the control panel. Of course, the length L2 indicated by the target marking line can also be pre-set in the control panel. Since the control panel 4 is communicatively connected with the ultrasonic mud level sensor 3, after the ultrasonic mud level sensor 3 measures the water depth L1 from the probe 54 to the surface of the mud layer, the control panel 4 can directly calculate and display the second mud thickness based on the distance L from the water surface to the bottom of the mud layer, the water depth L1 from the probe 54 to the surface of the mud layer, and the length L2 indicated by the marking scale line.

[0043] In summary, the first silt thickness D1 is the thickness of the silt layer measured manually. On this basis, the second silt thickness D2 is measured by the probe 54, etc., which is the thickness of the silt layer measured based on ultrasonic wave. At this time, it can be considered to combine the first silt thickness D1 and the second silt thickness D2 to obtain a more reasonable actual silt thickness and display it, such as taking the average value. From the above description, it can be seen that by adopting the dual operation of manual detection and ultrasonic detection to obtain the corresponding first silt thickness and second silt thickness, a more reasonable mud level data is obtained based on the first silt thickness and the second silt thickness to improve the accuracy of the detected silt layer thickness.

[0044] Furthermore, in the method for using the sludge thickness detection device of the present invention, step S3 includes the following steps: Drive the measuring rod to move along the first direction relative to the movable plate until the bottom end of the measuring rod along the first direction is inserted into the bottom surface of the silt layer through the limit bayonet 52, so as to form a silt mark and a water surface mark on the measuring rod; Taking the measuring rod out of the sludge layer and placing the measuring rod on the reference plate 22; The height of the silt mark and the height of the water surface mark are determined by the groove rod 21. The height of the silt mark is the first silt thickness, and the height of the water surface mark is the distance from the water surface to the bottom of the silt layer.

[0045] The height of the silt mark is the first silt thickness of the silt layer (the thickness of the silt layer measured manually). The height of the water surface mark is the distance from the water surface to the bottom of the silt layer. In practical applications, the measuring rod can be directly placed on the reference plate 22, and the height of the water surface mark can be directly measured by the ruler rod 21 and the telescopic rod 24. It can also be calculated by subtracting the length of the part of the long rod that is not wetted by the water surface from the total length of the measuring rod. It can be seen from the above description that the distance from the water surface to the bottom of the silt layer and the first silt thickness can be quickly obtained through the above manual measurement method, which can effectively assist ultrasonic detection and improve detection accuracy.

[0046] Please refer to Figures 1 to 5 , Embodiment 1 of the present invention is: a sludge thickness detection device, which can be used for sludge thickness detection in a water collection well of a hydropower station. Figure 1 As shown, the sludge thickness detection device includes a supporting component 1, a measuring component 2, an ultrasonic mud level sensor 3, a detection component 5, a control panel 4 and a measuring rod.

[0047] In this embodiment, if Figure 2 As shown, the support assembly 1 includes a support platform 11, a screw 13 and a drive motor 14. A track groove 12 is provided on the support platform 11. The screw 13 is rotatably arranged in the track groove 12 along its own axis. The drive motor 14 is arranged above the support platform 11, and the output shaft of the drive motor 14 is connected to the screw 13 in a transmission manner. An ultrasonic mud level sensor 3 and a control panel 4 are provided on one side wall of the support platform 11. The ultrasonic mud level sensor 3 is connected to the control panel 4 in communication. The ultrasonic mud level sensor 3 is used to display the data measured by the probe 54, and the control panel 4 can be used for the user to input the corresponding data, and the calculation is performed based on the input data and the data measured by the ultrasonic mud level sensor 3 and the probe 54, so as to calculate and display the actual mud thickness of the mud layer in the water collection well of the hydropower station.

[0048] In this embodiment, if Figure 3As shown, the detection assembly 5 includes a movable plate 51, a sleeve 53 and a probe 54. The movable plate 51 is threadedly connected to the screw 13. A threaded hole is provided on the movable plate 51. The movable plate 51 is threadedly connected to the screw 13 through the threaded hole. The movable plate 51 is driven to perform an up and down lifting operation through the rotation of the screw 13 and the driving motor 14, so that the probe 54 at the bottom can be extended into the water collection well of the hydropower station. At the same time, a limit bayonet 52 is also provided on the movable plate 51. The measuring rod is detachably arranged in the limit bayonet 52, and the limit bayonet 52 on the support plate is used for limit support. One end of the sleeve 53 is installed on the movable plate 51, and the other end of the sleeve 53 is provided with a probe 54. A marking scale line is also provided on the outer peripheral wall of the sleeve 53. A housing cavity for accommodating the connecting wire is provided in the sleeve 53. One end of the connecting wire is connected to the probe 54, and the other end passes through the housing cavity and is connected to the ultrasonic mud level sensor 3.

[0049] In this embodiment, if Figure 4 As shown, the measuring assembly 2 includes a ruler slot rod 21, a telescopic rod 24, a reference plate 22 and a protective shell 25. The ruler slot rod 21 is arranged on the outer side wall of the support platform 11, and the outer peripheral surface of the ruler slot rod 21 is provided with measuring scale lines. The reference plate 22 is partially installed at the bottom of the ruler slot rod 21, and a limit hole 23 is provided on the part of the reference plate 22 not covered by the ruler slot rod 21, and the limit hole 23 can be used to place the measuring rod. In addition, a receiving groove with an opening upward is provided in the ruler slot rod 21, and the telescopic rod 24 can be slidably arranged in the receiving groove, and the telescopic rod 24 is also provided with measuring scale lines. In practical applications, the telescopic rod 24 includes a plurality of connecting rods that are sleeved in sequence, and two adjacent connecting rods can be relatively telescopic. When the ruler slot rod 21 is not long enough, the telescopic rod 24 can be directly stretched. The protective shell 25 is arranged at the top of the telescopic rod 24, and an elastic buckle 26 is provided on the protective shell 25, and an embedding hole 27 for embedding the elastic buckle 26 is provided on the ruler slot rod 21. When the telescopic rod 24 is received in the accommodating cavity in the ruler slot rod 21 , the elastic buckle 26 can be embedded in the embedding hole 27 on the ruler slot rod 21 , so as to protect and limit the telescopic rod 24 in the accommodating cavity to prevent it from sliding out.

[0050] In summary, the silt thickness detection device and its use method provided by the present invention are as follows: the silt thickness detection device for the water collection well of a hydropower station adopts dual operation of manual and ultrasonic devices. When manual detection is required, the measuring rod is directly embedded in the silt of the water collection well of the hydropower station, and then the measuring rod is taken out and placed on the side of the ruler slot rod 21. Since the telescopic rod 24 is connected to the ruler slot rod 21, it is convenient to adjust the stretching length according to the silt mark of the measuring rod and the height of the water surface mark. When ultrasonic detection is required, the movable plate 51 is driven to move up and down by the rotation of the screw 13 and the drive motor 14, so that the probe 54 at the bottom can be extended into the water collection well of the hydropower station. According to the setting of the scale lines marked on the outer circumference of the sleeve rod, the probe 54 is fixed at a preset detection depth below the water surface in cooperation with the control panel 4. Since the end of the probe 54 is connected to the ultrasonic mud level sensor 3 through a connecting line, the silt layer in the water collection well of the hydropower station can be detected through the probe 54. In summary, in order to improve the accuracy of the test values, while conducting ultrasonic testing, it is possible to use a manually embedded measuring rod at one end to improve the detection accuracy.
