Description

Technical Field

[0001] This application relates to the field of water depth measurement technology, specifically to a water depth measurement device based on a telescopic tube. Background Technology

[0002] Depth measurement of static water bodies such as pits and ponds can accurately obtain underwater topographic data, providing reliable data support for water area planning. Currently, there are two common measurement methods: one is to use unmanned remote-controlled boats equipped with sonar equipment to calculate water depth by emitting sound waves and receiving echoes; the other is for personnel on the shore or in a boat to insert a depth measuring rod into the bottom of the water to directly read the water depth data.

[0003] However, the above measurement methods have certain drawbacks in some scenarios: sonar equipment is expensive and requires special transportation vehicles. When operating in scattered water areas such as pits and small reservoirs, it is necessary to frequently transfer the equipment across water areas, resulting in low operating efficiency. When traveling by boat, it is necessary to use boats to carry the operators, which is inconvenient for transportation and relocation. If the depth sounding rod is inserted directly into the bottom of the shore to read the data, it is limited by the operating radius and can only obtain data in shallow water areas near the shore, and cannot cover areas far from the shore or in deep water areas, resulting in low measurement efficiency. Utility Model Content

[0004] To address the problem of low measurement efficiency in existing technologies, this utility model provides a water depth measurement device based on a telescopic tube.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] This utility model provides a water depth measuring device based on a telescopic tube, characterized in that it includes:

[0007] The bracket has a sleeve 1 fixedly installed at one end, a slot 1 provided on the sleeve 1, a telescopic tube inserted into the slot 1, the telescopic tube being hollow inside, a sleeve 2 provided at the other end of the telescopic tube, a fixing frame fixedly installed at the end of the sleeve 2 away from the telescopic tube, a rotatable reel on the bracket, a measuring rope connected to the reel, and a guide hole on the bracket.

[0008] The fixed frame has a cavity, and a wheel frame is installed inside the cavity. A grooved wheel is rotatably mounted on the wheel frame. An insertion rod is fixedly mounted at the bottom of the wheel frame. The fixed frame has a through hole for fitting the insertion rod. A spring is sleeved on one end of the insertion rod inside the cavity. A limit switch is fixedly mounted above the wheel frame in the cavity. An indicator light is fixedly mounted on the top of the bracket or sleeve. A measuring cone is fixedly mounted on the other end of the measuring rope. The measuring rope passes through the guide hole and the inside of the telescopic tube and is wound around the grooved wheel.

[0009] Preferably, a fixing rod is fixedly installed at the bottom of the second sleeve, a ball joint seat is fixedly installed at the bottom of the fixing rod, a float plate is installed below the ball joint seat, and a mounting seat that matches the ball joint seat is fixedly installed on the float plate. The float plate has a positioning hole aligned with the measuring cone. When the telescopic tube and the second sleeve are moved to the measuring point on the water surface, the float plate at the bottom of the second fixing rod floats on the water surface. The float plate can provide certain support for the end of the second sleeve and the telescopic tube, making it easier for the staff to hold the support. Furthermore, the lower position of the measuring cone can be calibrated through the positioning hole on the float plate, ensuring that the measuring cone is accurately lowered to the water surface below the measuring point along the positioning hole.

[0010] Preferably, the second sleeve is provided with a second slot, and the end of the telescopic tube away from the first sleeve is inserted into the second slot. Both the first and second slots are provided with threaded through holes on their side walls, and limiting bolts are inserted into the threaded through holes. After the first and second sleeves are fitted onto the two ends of the telescopic tube, the limiting bolts are then inserted into the threaded through holes to tighten and limit the telescopic tube, so that the first sleeve, the second sleeve and the telescopic tube can be quickly installed and disassembled, and the operation is convenient.

[0011] Preferably, a motor is fixedly mounted on the bracket, and the output shaft of the motor is connected to one end of the reel. A switch module for controlling the rotation of the motor is also fixedly mounted on the bracket. The motor is electrically connected to the switch module via a wire. The switch module is equipped with a mechanical button, which can be used to adjust and control the forward and reverse rotation of the motor. The motor is a geared motor with a self-locking function. When the measuring rope is released, the operator presses the mechanical button of the switch module to start the motor. The motor output shaft drives the reel to rotate, thereby releasing the measuring rope. The operation is convenient. When the switch module shuts off the motor, the motor locks and limits the reel and the measuring rope to prevent the measuring rope from being accidentally released and to ensure the accuracy of the measurement.

[0012] Preferably, a limit rod is fixedly installed at the bottom of the fixed frame, with the top of the limit rod located inside the cavity. When the bottom of the wheel frame moves down, it can abut against the top of the limit rod. The top of the limit rod is located below the wheel frame. When the measuring cone presses down on the wheel frame through the measuring rope, the wheel frame moves down a certain distance and then abuts against the top of the limit rod, thus limiting the wheel frame and preventing it from descending excessively. This reduces the time the wheel frame abuts against the limit switch when it rises, thereby improving the accuracy of the measurement.

[0013] Preferably, a level is fixedly installed on the support. After the operator holds the support, he / she can observe and adjust the horizontal state of the entire device through the level to ensure the accuracy of the measurement.

[0014] Preferably, a battery compartment is fixedly installed on the top of the bracket or sleeve, and a battery pack is installed inside the battery compartment. The motor and indicator lights are electrically connected to the battery inside the battery compartment through wires to ensure the normal power supply and operation of the equipment.

[0015] The advantages of adopting the above technical solution are:

[0016] This utility model includes a support frame with a sleeve fixedly attached to one end. A slot is provided on the sleeve, and a telescopic tube is inserted into the slot. The telescopic tube is hollow. A second sleeve is attached to the other end of the telescopic tube, and a fixed frame is fixedly attached to the end of the second sleeve away from the telescopic tube. The fixed frame has a cavity containing a wheel frame with a grooved wheel rotatably mounted on it. A limit switch is fixedly attached to the top of the wheel frame, and an indicator light is fixedly attached to the top of the fixed frame. During measurement, the water depth at different points can be measured by adjusting and moving the telescopic tube, improving measurement efficiency. Furthermore, when the measuring cone contacts the bottom of the pit, the indicator light illuminates to alert the operator and ensure measurement accuracy. Attached Figure Description

[0024] like Figure 1-4 As shown, this utility model embodiment discloses a water depth measuring device based on a telescopic tube, including a support 1. A sleeve 2 is fixedly mounted at one end of the support 1, and a slot 201 is provided on the sleeve 2. A telescopic tube 3 is inserted into the slot 201. The telescopic tube 3 is hollow inside. A sleeve 4 is provided at the other end of the telescopic tube 3. A fixing frame 402 is fixedly mounted at the end of the sleeve 4 away from the telescopic tube 3. A reel 100 is rotatably mounted on the support 1, and a measuring rope 8 is connected to the reel 100. A guide hole 202 is provided on the support 1, and a cavity is provided inside the fixing frame 402. A wheel frame 403 is installed inside the cavity, and a grooved wheel 7 is rotatably mounted on the wheel frame 403. An insertion rod 4031 is fixedly mounted at the bottom of the wheel frame 403. A through hole for fitting the insertion rod 4031 is provided on the fixing frame 402. A spring 4032 is sleeved on one end of the insertion rod 4031 inside the cavity. A limit switch 404 is fixedly mounted above the wheel frame 403 in the cavity. An indicator light 405 is fixedly mounted on the top of the bracket 1 or the sleeve 2. A measuring cone 801 is fixedly mounted on the other end of the measuring rope 8, and the measuring rope 8 passes through the guide hole 202 and the inside of the telescopic tube 3 and is wound around the grooved wheel 7.

[0025] In at least one embodiment, a fixing rod 5 is fixedly installed at the bottom of the sleeve 2 4, a ball joint seat 501 is fixedly installed at the bottom of the fixing rod 5, a float plate 6 is installed below the ball joint seat 501, and a mounting seat that matches the ball joint seat 501 is fixedly installed on the float plate 6. The float plate 6 is provided with a positioning hole 601 aligned with the measuring cone 801. When the telescopic tube 3 and the sleeve 2 4 are moved to the measuring point on the water surface, the float plate 6 at the bottom of the fixing rod 2 5 floats on the water surface. The float plate 6 can provide certain support for the end of the sleeve 2 4 and the telescopic tube 3, making it easier for the staff to hold the bracket 1. Furthermore, the lower position of the measuring cone 801 can be calibrated through the positioning hole 601 on the float plate 6, ensuring that the measuring cone 801 is accurately lowered below the water surface of the measuring point along the positioning hole.

[0026] In at least one embodiment, the sleeve 2 4 is provided with a slot 2 401, and the end of the telescopic tube 3 away from the sleeve 1 2 is inserted into the slot 2 401. The side walls of both the slot 1 201 and the slot 2 401 are provided with threaded through holes, and a limiting bolt 203 is inserted into the threaded through holes. After the sleeve 1 2 and the sleeve 2 4 are fitted onto the two ends of the telescopic tube 3, the limiting bolt 203 is then inserted into the threaded through holes to tighten and limit the telescopic tube 3, so that the sleeve 1 2, the sleeve 2 4 and the telescopic tube 3 can be quickly installed and disassembled, and the operation is convenient.

[0027] In at least one embodiment, a motor is fixedly mounted on the bracket 1, and the output shaft of the motor is connected to one end of the reel 100. A switch module for controlling the rotation of the motor is also fixedly mounted on the bracket 1. The motor is electrically connected to the switch module through a wire. The switch module is equipped with a mechanical button, which can be used to adjust and control the forward and reverse rotation of the motor. The motor is a geared motor and has a self-locking function. When the measuring rope 8 is released, the operator presses the mechanical button of the switch module to start the motor. The output shaft of the motor drives the reel 100 to rotate, thereby releasing the measuring rope 8. The operation is convenient. When the switch module shuts off the motor, the motor locks and limits the reel 100 and the measuring rope 8 to prevent the measuring rope 8 from being accidentally released and to ensure the accuracy of the measurement.

[0028] In at least one embodiment, a limiting rod 406 is fixedly provided at the bottom of the fixed frame 402. The top of the limiting rod 406 is located in the cavity. When the bottom of the wheel frame 403 moves down, it can abut against the top of the limiting rod 406. The top of the limiting rod 406 is located below the wheel frame 403. When the measuring cone 801 presses down on the wheel frame 403 through the measuring rope 8, the wheel frame 403 moves down a certain distance and abuts against the top of the limiting rod 406, thus limiting the wheel frame 403 and preventing the wheel frame 403 from falling excessively. This reduces the time when the wheel frame 403 rises and abuts against the limit switch 404, thereby improving the accuracy of the measurement.

[0029] In at least one embodiment, a level 103 is fixedly installed on the support 1. After the operator holds the support 1, he / she can observe and adjust the horizontal state of the entire device through the level 103 to ensure the accuracy of the measurement.

[0030] In at least one embodiment, a battery compartment 407 is fixedly installed on the top of the bracket 1 or the sleeve 2. A battery pack is installed inside the battery compartment 407. The motor and the indicator light 405 are electrically connected to the battery pack inside the battery compartment 407 through wires to ensure the normal power supply and operation of the equipment.

[0031] In at least one embodiment, the indicator light 405 can be replaced by a buzzer. The battery in the battery compartment 407, the limit switch 404, and the indicator light 405 are connected in series to form a circuit. After the limit switch 404 abuts against the wheel frame 403, the indicator light 405 is powered on and illuminated, thereby prompting the operator and facilitating the subsequent work.

[0032] When measuring the depth of static water bodies such as pits and ponds, the operators connect the two ends of the telescopic pipe 3 to sleeve 2 and sleeve 4 respectively on the bank of the pit or pond. The telescopic pipe 3 is a multi-segment telescopic hollow tube. The operators can adjust the length of the telescopic pipe 3 according to the distance of the measurement points, which facilitates the measurement of the depth at different points and improves the applicability of this device. After the telescopic pipe 3 is installed, the movable end of the measuring rope 8 on the reel 100 is passed through the guide hole 202 on the bracket 1 and the inside of the telescopic pipe 3. Then the measuring rope 8 is wound around... On the grooved wheel 7 of the wheel frame 403, one end of the measuring rope 8 with the measuring cone 801 hangs vertically down at the grooved wheel 7. Then, the operator holds the support 1, adjusts the telescopic tube 3 to the length matching the measurement point, and moves the measuring cone 801 so that it is directly above the measurement point. The operator then rotates the reel 100 on the support 1, releasing the measuring rope 8, causing the measuring cone 801 at the other end to descend vertically below the water surface. During the descent of the measuring cone 801... The weight of the measuring cone 801 presses down on the grooved wheel 7 and the wheel frame 403, compressing the spring 4032 below the wheel frame 403. When the measuring cone 801 descends to contact the bottom of the pit, it reduces its downward pressure on the wheel frame 403. At this time, the spring 4032 pushes the wheel frame 403 upward, causing the top of the wheel frame 403 to contact the limit switch 404. A battery compartment 407 is fixedly installed on the top of the fixing frame 402. The battery, limit switch 404, and indicator light inside the battery compartment 407 are connected in series as a circuit via wires. When valve 404 comes into contact with wheel frame 403, the indicator light is turned on, and the operator stops rotating wheel 100. The measuring rope 8 has scale lines, and the operator can read the scale lines when the measuring cone 801 enters the water and touches the bottom to calculate the water level depth at the measuring point. The operation is convenient and improves the measurement efficiency. In order to ensure the accuracy of the measurement, multiple measurements can be taken at the same point. After the measurement is completed, the measuring rope 8 is retrieved through wheel 100, and then the telescopic tube 3 is processed to shorten it. The operation is convenient.

[0033] In at least one embodiment, the indicator light 405 can be replaced by a buzzer. The battery in the battery compartment 407, the limit switch 404 and the buzzer are connected in series to form a circuit. After the limit switch 404 abuts against the wheel frame 403, the buzzer is powered on and sounds, thereby prompting the operator and facilitating the subsequent work.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
