For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0035] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0036] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a sand content detection device, including a telescopic rod 100 and a photoelectric probe 200. The telescopic rod 100 is configured to be able to extend and retract along its own extension direction; the photoelectric probe 200 is arranged at the bottom end of the telescopic rod 100, and the photoelectric probe 200 is provided with at least one detection channel 210, and a light source 211 and a receiving element 212 are arranged in the detection channel 210.
[0037] Specifically, the telescopic rod 100 is configured as a long round rod, a connector is provided at the bottom end of the telescopic rod 100, and the photoelectric probe 200 is fixed to the bottom end of the telescopic rod 100 through the connector. The telescopic rod 100 can realize its telescopic movement by means of multi-stage sleeves or screw nuts. The photoelectric probe 200 is spherical as a whole, the detection channel 210 is configured as a detection hole that runs through the photoelectric probe 200, the light source 211 is configured in the detection hole to emit light, and the receiving element 212 is fixed in the detection hole to receive the reflected light. Therefore, when the photoelectric probe 200 is extended into the sand-containing water body, the position of the photoelectric probe 200 in the sand-containing water body can be adjusted by the telescopic movement of the telescopic rod 100. At the same time, if the detection channel 210 is blocked by obstacles such as garbage or leaves, the system can drive the telescopic movement of the photoelectric probe 200 through the telescopic rod 100 to try to get rid of the monitoring obstacle.
[0038] That is, the utility model provides a sand content detection device, which sets a photoelectric switch at the lower end of a telescopic rod 100 that can be extended and retracted, and adjusts the position of a photoelectric probe 200 in water by extending and retracting the telescopic rod 100, thereby adjusting the detection depth of the photoelectric probe 200. This solves the problem that the sand content detection device in the prior art cannot adjust the detection depth, and when facing a water channel with a large fluctuation in the liquid level height, the measurement data will fluctuate greatly, or even be difficult to detect. This improves the detection accuracy and detection adaptability of the sand content detection device.
[0039] Furthermore, the sand content detection device also includes an ultrasonic probe 300, which is disposed at the bottom end of the telescopic rod 100, and the ultrasonic probe 300 is used to detect the distance between the photoelectric probe 200 and the water surface.
[0040] Specifically, the ultrasonic probe 300 is fixed to the bottom end of the telescopic rod 100 and moves with the movement of the telescopic rod 100. The ultrasonic probe 300 can emit ultrasonic signals toward the water surface, and determine the distance between it and the water surface through the reflected ultrasonic signals, thereby judging the distance between the photoelectric probe 200 and the water surface, so as to obtain the position information of the photoelectric probe 200 in the sandy water body, and provide conditions for the telescopic rod 100 to adjust the position of the photoelectric probe 200.
[0041] Preferably, the ultrasonic probe 300 is disposed at the bottom end of the telescopic rod 100 along the horizontal direction.
[0042] Specifically, the ultrasonic probe 300 is fixed on the telescopic rod 100 in a direction perpendicular to the extension direction of the telescopic rod 100, and the telescopic rod 100 maintains its value when extending into the sandy water body, which ensures that the ultrasonic probe 300 can be in a horizontal direction. Since the ultrasonic probe 300 is set horizontally, the water or dew splashed in the water flow will gather on the side wall of the ultrasonic probe 300 instead of gathering on the head of the ultrasonic probe 300, avoiding its influence on the measurement accuracy of the ultrasonic probe 300.
[0043] Furthermore, a polymer plate 310 is disposed at the detection end of the ultrasonic probe 300 . The polymer plate 310 is disposed at an angle with the horizontal direction and is disposed toward the water surface.
[0044] Specifically, the polymer plate 310 is fixed to the detection end of the ultrasonic probe 300, and its function is to transmit the ultrasonic signal to the water surface and receive the ultrasonic signal reflected by the water surface. In this embodiment, the polymer plate 310 is at an angle of 45° to the horizontal direction and is arranged upward at the detection end of the ultrasonic probe 300. Therefore, even if water adheres to the polymer plate 310, it will be affected by gravity and converge to the bottom of the polymer plate 310, and will not affect the signal transmission of the polymer plate 310, thereby ensuring the measurement accuracy of the ultrasonic probe 300.
[0045] Furthermore, a plurality of detection channels 210 are disposed on the photoelectric probe 200 , and the plurality of detection channels 210 are evenly disposed on the photoelectric probe 200 .
[0046] Specifically, in the present embodiment, two detection channels 210 are provided, which are arranged in parallel in the horizontal direction in the photoelectric probe 200. In other embodiments of the present application, other numbers of detection channels 210 may also be provided, and those skilled in the art may set them by themselves according to the detection requirements. By setting multiple detection passes, an average value can be taken based on the detection results of multiple detection channels 210 to improve the detection accuracy. At the same time, it is determined whether the detection results are within the normal fluctuation range to determine when the detection channel 210 is subject to detection obstacles. For example, when one side of the channel water inlet is blocked by garbage (especially plastic bags or leaves) blocking the water inlet of the detection channel 210, the detection channel 210 will be in a detection obstacle state. At this time, the detection channel 210 can be freed from the detection obstacle by the telescopic movement of the telescopic rod 100.
[0047] Furthermore, the sand content detection device also includes a wireless communication module 400. A receiving cavity 110 is provided in the telescopic rod 100. The wireless communication module 400 is disposed in the receiving cavity 110. The wireless communication module 400 is connected to the ultrasonic probe 300 and the photoelectric probe 200 respectively.
[0048] Specifically, the bottom end of the telescopic rod 100 is hollowed to form a receiving cavity 110. The wireless communication module 400 is fixed in the receiving cavity 110 by bolts, mounting brackets and other mounting parts. The wireless communication module 400 is electrically connected to the ultrasonic probe 300 and the photoelectric probe 200 through wires, so as to transmit the data detected by the ultrasonic probe 300 and the photoelectric probe 200 to the detection personnel by wireless transmission, so as to facilitate the detection personnel to remotely control the sand content detection equipment and remotely analyze the detection data.
[0049] Preferably, the sand content detection device further includes an alarm module, which is disposed in the accommodating cavity 110 and connected to the wireless communication module 400 .
[0050] Specifically, the alarm module can be fixed in the receiving cavity 110 by bolts, mounting brackets and other mounting parts, and connected to the wireless communication module 400 by wires. When the detection data of the detection channel 210 shows abnormal fluctuations, the alarm module will generate an alarm signal and transmit it to the detection personnel through the wireless communication module 400. Thus, the detection personnel can find the data abnormality in time, manually intervene in the data detection, and handle the abnormality.
[0051] Furthermore, the sand content detection equipment also includes a power supply 500 and a control module 600. The power supply 500 is connected to the control module 600. The power supply 500 and the control module 600 are both arranged in the accommodating cavity 110. The control module 600 is respectively connected to the alarm module, the ultrasonic probe 300, the wireless communication module 400 and the photoelectric probe 200.
[0052] Specifically, the power supply unit 500 and the control module 600 are fixed in the accommodating cavity 110 by bolts, mounting brackets and other mounting parts. The control module 600 is connected to the alarm module, the ultrasonic probe 300, the wireless communication module 400 and the photoelectric probe 200 by wires to collect the detected data, analyze it, and provide instructions for the telescopic movement of the wireless communication module 400, the alarm module and the telescopic rod 100. In other embodiments of the present application, the sand content detection device can also be directly connected to an external power supply by a wire, and the power supply unit 500 is used as a backup power supply to avoid power failure and shutdown of the sand content detection device.
[0053] Furthermore, the sand content detection equipment also includes a sleeve rod and a driving device. The sleeve rod is hollow and sleeved on the telescopic rod 100. The driving device is fixed in the sleeve rod. The driving end of the driving device is connected to the telescopic rod 100 to drive the telescopic rod 100 to move along its extension direction.
[0054] Specifically, the sleeve rod can be set as a hollow round rod with the same shape as the telescopic rod 100, and is sleeved outside the telescopic rod 100, so that the telescopic rod 100 can slide and retract inside the sleeve rod. The driving device can be set as an electric push rod, a cylinder or a screw motor, and its driving end extends into the sleeve rod and is connected to the top of the telescopic rod 100, thereby driving the telescopic movement of the telescopic rod 100. The driving device can be connected to the control module 600 and the power supply 500 to realize automatic control of the telescopic movement of the telescopic rod 100, thereby improving the automation of the sand content detection equipment.
[0055] Preferably, a plurality of sleeve rods are provided, and the plurality of sleeve rods are sleeved and connected in sequence.
[0056] Specifically, the sizes of the plurality of sleeve rods gradually increase and match each other so as to be sleeved and connected in sequence. The first sleeve rod is sleeved on the outside of the telescopic rod 100, and the last sleeve rod is connected to the driving device. By providing a plurality of sleeve rods connected in sequence, the telescopic range of the telescopic rod 100 can be effectively extended, and the detection depth of the sand content detection device can be increased.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
