DETAILED DESCRIPTION

[0030] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] Embodiment 1

[0032] As attached Figure 1 To Attachment Figure 4 As shown, this embodiment provides a water level measuring device, including a measuring component 1, wherein the measuring component 1 is used to measure the height of the water level, the measuring component 1 is connected to a folding component 2, wherein the folding component 2 can rotate, and after the rotation, a part of the folding component 2 and a cleaning component 3 can be adjusted to the measuring component 1, thereby reducing the space occupied by the device and improving the convenience, the folding component 2 is connected to the cleaning component 3, when the measuring component 1 is rolled up, the cleaning component 3 wipes off the water stains and pollutants attached to the measuring component 1 during the measurement process, thereby extending the service life of the device;

[0033] The folding assembly 2 includes a folding arm 201, wherein the folding arm 201 can rotate. When the folding arm 201 rotates and unfolds, the cleaning assembly 3 is taken out from the measuring assembly 1. When the folding arm 201 rotates and retracts, the cleaning assembly 3 is adjusted into the measuring assembly 1 for easy storage.

[0034] The cleaning component 3 includes a mounting frame 301 fixedly connected to the folding arm 201. When the device is in use, the steel ruler cable 102 and the measuring probe 103 of the measuring component 1 will pass through the mounting frame 301. The mounting frame 301 is provided with a sliding hole. The mounting frame 301 is slidably connected to the sliding rod 302 through the sliding hole. The sliding rod 302 can slide on the mounting frame 301. One end of the sliding rod 302 is fixedly connected to an anti-slip plate 303. Both ends of the sliding rod 302 are provided with an anti-slip plate 303 and a cleaning wipe 304. The sizes of the anti-slip plate 303 and the cleaning wipe 304 are both larger than the diameter of the sliding hole. , which can prevent the sliding rod 302 from being separated from the mounting frame 301. The other end of the sliding rod 302 is fixedly connected with a cleaning wipe 304. The steel ruler cable 102 and the measuring probe 103 of the measuring component 1 rub against the cleaning wipe 304 during movement. At this time, the cleaning wipe 304 wipes and cleans the steel ruler cable 102 and the measuring probe 103 of the measuring component 1. A first spring 305 is sleeved on the peripheral side of the sliding rod 302. The first spring 305 provides a thrust, so that the cleaning wipe 304 is always in contact with the steel ruler cable 102 and the measuring probe 103 of the measuring component 1, thereby improving the wiping effect.

[0035] As can be seen from the above, when using the device, place it stably, rotate the folding arm 201 to take the cleaning component 3 out of the measuring component 1, insert the steel ruler cable 102 and the measuring probe 103 of the measuring component 1 into the installation frame 301, and then measure the water level. When the water level measurement is completed, reel in the steel ruler cable 102 and the measuring probe 103, and the first spring 305 provides a thrust to move the sliding rod 302 toward the steel ruler cable 102 and the measuring probe 103, thereby ensuring that the cleaning wipe 304 is in contact with the steel ruler cable 102 and the measuring probe 103 of the measuring component 1. During the process of reeling in the steel ruler cable 102 and the measuring probe 103, the cleaning wipe 304 wipes and cleans the steel ruler cable 102 and the measuring probe 103 of the measuring component 1 to prevent water stains from corroding the steel ruler cable 102 and the measuring probe 103. At the same time, the surfaces of the steel ruler cable 102 and the measuring probe 103 after wiping are clearer, which is also convenient for checking the condition of the equipment. While the steel ruler cable 102 is reeling in, the cleaning wipe 304 performs a wiping action, which improves the speed of equipment maintenance. At the same time, manual wiping is no longer required, which reduces the difficulty of equipment maintenance.

[0036] Embodiment 2

[0037] As attached Figure 1 To Attachment Figure 4 As shown, this embodiment is basically the same as the previous embodiment, except that one end of the first spring 305 is fixedly connected to the anti-drop plate 303, and the other end of the first spring 305 is fixedly connected to the mounting frame 301, so as to avoid the first spring 305 from deflecting. The upper and lower ends of the cleaning wipe 304 are respectively provided with guide slopes 306. When the measuring probe 103 contacts the cleaning wipe 304, the guide slopes 306 make the cleaning wipe 304 and the sliding rod 302 slide in the sliding hole. At this time, the two cleaning wipes 304 move away from each other, adapting to the size of the measuring probe 103. The brush heads of the two cleaning wipes 304 are arranged opposite to each other, and the cleaning wipe 304 is located in the frame of the mounting frame 301.

[0038] Specifically, the cleaning component 3 also includes a mounting groove 307 provided on the folding arm 201. By providing the mounting groove 307, space is provided in the folding arm 201 for installing a guide wheel 308, making the structure more compact. The mounting groove 307 is rotatably connected to the guide wheel 308, and the guide wheel 308 is located above the mounting frame 301. The steel ruler cable 102 and the measuring probe 103 are guided by the guide wheel 308 and pass through the mounting frame 301, ensuring that the steel ruler cable 102 and the measuring probe 103 are located in the middle position of the mounting frame 301, thereby ensuring the cleaning effect.

[0039] Furthermore, the measuring component 1 includes a winding roller 101, which retracts and releases a steel ruler cable 102 by rotating the winding roller 101 forward and reversely. The winding roller 101 is wrapped with the steel ruler cable 102, and the steel ruler cable 102 has the function of measuring the water level and transmitting the signal of the measuring probe 103. The end of the steel ruler cable 102 away from the winding roller 101 is connected to the measuring probe 103, and the sound emitted by the measuring probe 103 is used to determine whether it is in contact with the water surface or the bottom of the water.

[0040] Furthermore, the measuring component 1 also includes a baffle 104 rotatably connected to both sides of the winding roller 101, the baffle 104 limits the wound steel ruler cable 102 to prevent the steel ruler cable 102 from deviating, and the baffle 104 remains fixed when the winding roller 101 retracts and releases the steel ruler cable 102, and the baffle 104 is fixedly connected to a support frame 105, which provides support for the winding roller 101 and provides space for the rotation of the winding roller 101, and the support frame 105 is connected to a lifting handle 106, which is used to facilitate carrying the device, and the support frame 105 and the lifting handle 106 are integrally formed, and the support frame 105 is fixedly connected to an insert tube 107, and in order to facilitate the storage of the measuring probe 103, when the winding roller 101 has finished winding up the steel ruler cable 102, the measuring probe 103 can be inserted into the insert tube 107.

[0041] As can be seen from the above, the device is moved to the measuring area by pulling the handle 106, and the device is placed horizontally by the support frame 105. When measuring the water level, the steel ruler cable 102 is released outside by rotating the winding roller 101 forward, and the steel ruler cable 102 is placed on the guide wheel 308. The steel ruler cable 102 and the measuring probe 103 pass through the installation frame 301 and sink into the water to measure the water level. After the measurement, the winding roller 101 is reversed to roll up the steel ruler cable 102. The first spring 305 provides thrust to make the cleaning wipe 304 always fit with the steel ruler cable 102 or the measuring probe 103. During the winding process, the cleaning wipe 304 cleans the steel ruler cable 102 and the measuring probe 103. After the steel ruler cable 102 is wound up, the measuring probe 103 is inserted into the insert 107 for storage.

[0042] Embodiment 3

[0043] As attached Figure 5 To Attachment Figure 6As shown, this embodiment is basically the same as the previous embodiment, with the difference that the folding component 2 also includes a mounting rod 202 rotatably connected to the folding arm 201, the mounting rod 202 is located between the two baffles 104, the mounting rod 202 cooperates with the folding arm 201, the folding arm 201 can be rotated in between the two baffles 104, or rotated out from between the two baffles 104, the mounting rod 202 is provided with a first limit plate 203 and a second limit plate 204, the folding arm 201 is located between the first limit plate 203 and the second limit plate 204, wherein the first limit plate 203 is used to limit the maximum angle of the folding arm 201 rotating into the two baffles 104, and the second limit plate 204 is used to limit the maximum angle of the folding arm 201 rotating out of the two baffles 104.

[0044] Specifically, the folding component 2 also includes a limiting gear 205 fixedly connected to the folding arm 201. When the folding arm 201 rotates, the limiting gear 205 will rotate together with it. The mounting rod 202 is fixedly connected to the limiting strip 206, wherein the end of the limiting strip 206 away from the mounting rod 202 extends into the tooth gap of the limiting gear 205. When the limiting gear 205 rotates, it will continuously move the limiting strip 206. The limiting strip 206 plays a certain limiting role in the rotation of the limiting gear 205, which can prevent the folding arm 201 from shaking randomly during storage, movement, and use.

[0045] Furthermore, the cross-section of the limit bar 206 is wavy. By setting the limit bar 206 to a special shape, the elasticity of the limit bar 206 can be increased, which is beneficial to the resetting of the limit bar 206, thereby ensuring that the limit bar 206 plays a certain limiting role in the rotation of the limit gear 205. The cross-section of the folding arm 201 is arc-shaped. By setting the shape of the folding arm 201, it is convenient for the folding arm 201 to be turned into the two baffles 104 for storage.

[0046] Furthermore, it also includes a disassembly assembly 4, wherein the folding assembly 2 and the cleaning assembly 3 have wearing parts, and need to be repaired or replaced after long-term use. By setting the disassembly assembly 4, it is convenient to separate the mounting rod 202 and the baffle 104, so as to facilitate the repair or replacement of the folding assembly 2 and the cleaning assembly 3. The disassembly assembly 4 includes an insertion hole 401 opened on the baffle 104 and the mounting rod 202, and the insertion hole 401 is movably connected with the insertion rod 402. When the insertion rod 402 is inserted into the insertion hole 401, the baffle 104 and the mounting rod 202 are connected together, and the insertion rod 402 is fixedly connected There is a pull-out plate 403, by holding the pull-out plate 403, it is convenient to pull the insertion rod 402 out of the insertion hole 401. The insertion rod 402 is sleeved with a second spring 404. When the insertion rod 402 is pushed in or pulled out from the insertion hole 401, the second spring 404 is deformed, and a limiting protrusion 405 is provided on the surrounding side of the insertion rod 402, and a movable groove 406 is opened on the surrounding side of the insertion hole 401. The limiting protrusion 405 is slidably matched with the movable groove 406. During normal use, the limiting protrusion 405 is located in the short groove 406a of the movable groove 406, and the insertion rod 402 cannot be pulled out from the insertion hole 401.

[0047] Furthermore, the second spring 404 is fixedly connected to the pull-out plate 403 to prevent the second spring 404 from being lost. The movable groove 406 is composed of a short groove 406a, an arc groove 406b and a long groove 406c. The limiting protrusion 405 is pushed from the short groove 406a into the arc groove 406b, and the insertion rod 402 is rotated to make the limiting protrusion 405 turn into the long groove 406c. At this time, the insertion rod 402 can be pulled out from the insertion hole 401 along the long groove 406c.

[0048] As can be seen from the above, when working, the folding arm 201 is rotated out from between the two baffles 104. As the folding arm 201 rotates, the folding arm 201 finally contacts the second limit plate 204. At this time, the folding arm 201 rotates forward to the maximum angle, and then the steel ruler cable 102 and the measuring probe 103 are passed through the mounting frame 301 to measure the water level. When storing, the folding arm 201 is rotated between the two baffles 104. As the folding arm 201 rotates, the folding arm 201 finally contacts the first limit plate 203. The folding arm 201 rotates in the opposite direction to the maximum angle. During the artificial rotation of the folding arm 201, the limit gear 205 continuously moves the limit bar 206, and the limit bar 206 returns to its original position by its own elasticity. At this time, the limit bar 206 does not prevent the artificial rotation of the folding arm 201. Since the limit bar 206 is inserted into the tooth gap of the limit gear 205, the limit bar 206 has a certain limit effect on the rotation of the limit gear 205, which can prevent the folding arm 201 from shaking randomly during storage, movement, and use.

[0049] When the folding component 2 or the cleaning component 3 needs to be replaced or repaired, the pull-out plate 403 is pressed to move the insertion rod 402 to the depth of the insertion hole 401, and the limiting protrusion 405 moves along the short groove 406a. When the limiting protrusion 405 moves to the intersection of the short groove 406a and the arc groove 406b, the insertion rod 402 is rotated to move the limiting protrusion 405 from the intersection of the short groove 406a and the arc groove 406b to the intersection of the arc groove 406b and the long groove 406c. At this time, the insertion rod 402 can be pulled out of the insertion hole 401 along the long groove 406c. Since the insertion rod 402 is pulled out, the mounting rod 202 and the baffle 104 are separated, which facilitates the removal of the folding component 2 for replacement or repair.
