Description

Technical Field

[0001] This utility model relates to the field of water temperature measurement technology, and in particular to a locking mechanism and a multi-layer water temperature moving measurement and detection device. Background Technology

[0002] In current river hydrological monitoring, the acquisition of water temperature and water level data still relies on discrete measurement tools. Traditional water level measurement devices need to be fixedly installed and cannot collect water temperature data simultaneously. Water temperature measurement generally uses single-point probes, which require manual repeated retrieval and adjustment of depth position. For example, when acquiring vertical profile water temperature data of a river, operators need to lower and retrieve the equipment multiple times and record the data layer by layer, which is not only inefficient, but more seriously, single-point sampling cannot reflect the cross-sectional temperature gradient. Ignoring thermal stratification will directly affect the accuracy of ecological assessment and engineering design.

[0003] Existing integrated water level and temperature dual-function measurement equipment lacks an adaptive depth adjustment mechanism. When measuring different water depths, the operation must be interrupted and the probe manually adjusted, making it unable to adapt to dynamic changes. On the other hand, the equipment cannot achieve continuous scanning of the transverse cross section, and it needs to be repositioned and deployed each time it is moved to a new location, resulting in low efficiency. In addition, in order to reduce the carrying of external power supply equipment, photovoltaic panels are often integrated on the surface of the cabin cover to supply power to the equipment inside the cabin. However, when the cover is flipped over periodically for equipment maintenance, the existing locking mechanism is cumbersome to operate and difficult to open, which seriously restricts the maintenance efficiency. Summary of the Invention

[0004] Therefore, the technical problem to be solved by this utility model is that the opening process of existing ship hatch covers is cumbersome, which affects the work and maintenance efficiency of staff.

[0005] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes a locking mechanism, which includes a locking member, the locking member including a locking spring and a lock head connected to each other, and a plate for fixing the locking spring and the lock head;

[0006] The locking spring extends through the inside of the lock head.

[0007] In a preferred embodiment of the locking mechanism of this utility model: the locking spring includes a bent portion;

[0008] The lock head has a first through hole that penetrates its interior. The locking spring is squeezed by the inner wall of the first through hole, causing the locking spring to deform along the bend.

[0009] In a preferred embodiment of the locking mechanism of this utility model: the side wall of the lock head is provided with a second through hole that is intersecting the through direction of the first through hole;

[0010] A cylinder is provided inside the second through hole;

[0011] The insert plate passes through the second through hole and extends to the first through hole;

[0012] The end of the insert plate can abut against the outer wall of the locking spring.

[0013] In a preferred embodiment of the locking mechanism of this utility model: a groove is provided on the surface of the insert plate, and the groove is adapted to the cylinder;

[0014] When the groove abuts against the cylinder, flipping the insert plate can push out the locking spring.

[0015] The beneficial effects of this utility model are as follows: the locking spring can be unlocked from the lock head by inserting the plate, the locking spring is compressed by pushing the plate, and then the plate is flipped to move the locking spring away from the lock head, thereby separating the plate from the lock head; the locking mechanism has a simple structure and is easy to operate, which improves the work efficiency of the staff to a certain extent.

[0016] In addition, the technical problem that this utility model also needs to solve is that existing water temperature detection devices require repeated manual measurements, which results in high labor intensity for workers.

[0017] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes a multi-layer water temperature moving measurement and detection device, which includes a carrier and an airbag arranged around the outer wall of the carrier. The carrier is used to support other accessories.

[0018] A cover plate is installed at the top opening of the support member, and the cover plate is hinged to the support member; the support member and the cover plate are connected and fixed by the locking member.

[0019] The detection element is disposed on the outside of the carrier;

[0020] The receiving and releasing component has its lead wire wound around the outer wall of the receiving and releasing component's roller, thereby changing the water layer height where the detection component is located.

[0021] In a preferred embodiment of the multi-layer water temperature moving measurement and detection device of this utility model: a photovoltaic panel is installed on the upper surface of the cover plate;

[0022] A storage battery is installed inside the support member. The storage battery is connected to the photovoltaic panel via wires and provides power for the operation of the equipment.

[0023] The take-up and unwinding component includes a motor installed inside the carrier, a pulley connected to the output end of the motor, and a take-up roller driven by the pulley;

[0024] The outer wall of the take-up roller is wound with a wire connected to the detection element.

[0025] In a preferred embodiment of the multi-layer water temperature movement measurement and detection device of this utility model: a counterweight is provided at the bottom of the detection element, and the detection element can move into the deeper water layer when the winding roller unwinds due to the weight of the counterweight.

[0026] In a preferred embodiment of the multi-layer water temperature moving measurement and detection device of this utility model: infrared detection modules are provided at the four corners of the outer wall of the support member. The infrared detection modules can detect obstacles in the river channel, making it easier for the support member to avoid them.

[0027] In a preferred embodiment of the multi-layer water temperature moving measurement and detection device of this utility model, it further includes a PLC control module installed inside the carrier, the PLC control module being connected to a touch display panel via a circuit, and the PLC control module being connected to the wires of the detection component;

[0029] A powered propeller is installed at the bottom of the carrier and is connected to the PLC control module.

[0030] The beneficial effects of this utility model are as follows: the PLC control module can accurately control the depth of the detection component in the water to ensure the accuracy of water level and temperature detection; the winding component can be used to reel in the wire of the detection component, thereby controlling the detection component to be located in different water layers, thus enabling the detection of water temperature at different depths; and the device is equipped with a solar panel and a battery, which can ensure the supply of power during long-term operation, so that the water temperature detection device can operate for a long time.

[0038] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0039] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0040] Reference Figure 1 , Figure 4 and Figure 5 This embodiment provides a locking mechanism, including a locking member 7. The carrier member 1 and the cover plate 2 are connected and fixed through the locking member 7. The locking member 7 includes a locking spring 71 connected to the cover plate 2, a lock head 72 connected to the carrier member 1, and an insert plate 73 for fixing the locking spring 71 and the lock head 72. The locking spring 71 extends through to the inside of the lock head 72.

[0041] It should be noted that, in order to prevent river water from entering the interior of the carrier 1 during the movement of the detection device, it is necessary to ensure that the carrier 1 and the cover plate 2 are in a sealed state; and a sealing gasket is provided at the contact position between the cover plate 2 and the carrier 1; the sealing gasket can seal the gap between the carrier 1 and the cover plate 2, effectively preventing river water from entering the interior of the carrier 1 and affecting the operation of the equipment.

[0042] It should be noted that when the detection device is running in the river, the cover plate 2 and the carrier 1 need to be fixed together by the locking member 7; the locking spring 71 is connected to the cover plate 2 by bolts, and the lock head 72 is connected to the carrier 1 by bolts; when it is necessary to connect the cover plate 2 and the carrier 1, the locking spring 71 is inserted into the lock head 72 by flipping the cover plate 2, and then the locking spring 71 is fixed in the lock head 72 by the reverse elastic force generated by the deformation of the locking spring 71 itself, thereby fixing the position between the cover plate 2 and the carrier 1.

[0043] Furthermore, the lock head 72 has a second through hole 722 on its side wall that is intersecting the through direction of the first through hole 721; a cylinder 723 is provided inside the second through hole 722; the insert plate 73 passes through the second through hole 722 and extends to the first through hole 721; the end of the insert plate 73 can abut against the outer wall of the locking spring 71.

[0044] It should be noted that the lock head 72 has a first through hole 721 in the vertical direction and a second through hole 722 in the horizontal direction, and the first through hole 721 and the second through hole 722 are interconnected; the locking spring 71 passes through the first through hole 721 and is deformed by compression, so that the side wall of the locking spring 71 completely abuts against the inner wall of the first through hole 721, thereby fixing the position between the locking spring 71 and the lock head 72.

[0045] Specifically, the locking spring 71 has a V-shaped structure. When the locking spring 71 is deformed by the inner wall of the first through hole 721, the locking spring 71 bends inward. The reverse deformation force generated by the bending of the locking spring 71 is applied to the inner wall of the first through hole 721 to fix the position between the locking spring 71 and the lock head 72.

[0046] Furthermore, the insert plate 73 has a groove 731 on its surface, which is adapted to the cylinder 723; when the groove 731 abuts against the cylinder 723, flipping the insert plate 73 can push out the locking spring 71.

[0047] It should be noted that when it is necessary to push the locking spring 71 to deform and separate the locking spring 71 from the lock head 72, the insert plate 73 is inserted into the second through hole 722, and the end of the insert plate 73 abuts against the outer wall of the locking spring 71. The outer wall of the locking spring 71 is squeezed by the insert plate 73 and thus deforms. When the locking spring 71 is squeezed by the insert plate 73, the locking spring 71 bends further inward, so that the side wall of the locking spring 71 moves away from the inner wall of the first through hole 721. At this time, the locking spring 71 can be separated from the inside of the lock head 72.

[0048] Specifically, as the insertion plate 73 is inserted into the second through hole 722, the distance increases, causing the groove 731 to coincide with the position of the cylinder 723. At this time, the insertion plate 73 can rotate at a certain angle inside the second through hole 722. By rotating the insertion plate 73, the locking spring 71 can be deformed and moved upward simultaneously, thereby separating the locking spring 71 from the lock head 72.

[0049] In use, when it is necessary to fasten the cover plate 2 to the top opening of the carrier 1, flip the cover plate 2 and press down the locking spring 71 simultaneously, so that the locking spring 71 moves towards the first through hole 721; the two sides of the locking spring 71 abut against the inner wall of the first through hole 721, and the side wall of the locking spring 71 deforms during the compression process of the inner wall of the first through hole 721. Through the reverse force generated by the deformation of the locking spring 71, the locking spring 71 is fixed inside the first through hole 721.

[0050] When it is necessary to separate the cover plate 2 from the carrier 1, the insert plate 73 can be inserted into the second through hole 722, and the end of the insert plate 73 is pushed to abut against the outer wall of the locking spring 71. As the insert plate 73 abuts against the outer wall of the locking spring 71, the locking spring 71 bends inward along the bending part 711. After the locking spring 71 is bent, one side of it moves away from the inner wall of the first through hole 721. As the insert plate 73 is continuously inserted into the second through hole 722, the groove 731 coincides with the position of the cylinder 723. At this time, the insert plate 73 can rotate along the axis of the cylinder 723. Then, the insert plate 73 is pressed down, so that the end of the insert plate 73 that abuts against the locking spring 71 is raised. Then, the lifting of the end of the insert plate 73 drives the locking spring 71 to disengage from the first through hole 721.

[0051] Reference Figures 1-3 This embodiment provides a multi-layer water temperature moving measurement and detection device, including a carrier 1, and an airbag 11 is arranged around the outer wall of the carrier 1. The carrier 1 is used to support other accessories.

[0052] It should be noted that the carrier 1 has a rectangular structure and an airbag 11 is provided around the outer wall of the carrier 1. When the carrier 1 needs to float on the surface of the river, the airbag 11 is inflated by inflating it, which can ensure that the carrier 1 can float stably on the surface of the river.

[0053] The support component 1 is a plate-shaped structure with an open top and a sealed bottom; there are a large number of cavities inside the support component 1 to ensure that enough equipment can be installed inside.

[0054] Cover plate 2 is installed at the top opening of the support member 1, and the cover plate 2 is hinged to the support member 1; photovoltaic panel 3 is installed on the upper surface of cover plate 2.

[0055] It should be noted that the cover plate 2 and the carrier 1 are hinged together by a hinge. When the testing equipment is running normally, the cover plate 2 is fastened to the top opening of the carrier 1. At the same time, the horizontal arrangement of the cover plate 2 can better absorb sunlight for power generation and energy storage.

[0056] When maintenance and repair of the equipment inside the carrier 1 are required, the top opening of the carrier 1 can be opened by flipping the cover plate 2, which makes it easier for staff to quickly maintain and repair the equipment inside the carrier 1.

[0057] Battery 4 is installed inside the support component 1. Battery 4 is connected to photovoltaic panel 3 by wires and provides power for equipment operation. Detection component 6 is used to measure water level and water temperature at different heights. Retracting component 5 has the wires of detection component 6 wound around the outer wall of the roller of retracting component 5. Retracting component 5 retracts and releases the wires, thereby changing the water layer height of detection component 6.

[0058] It should be noted that the storage battery 4 is connected to the photovoltaic panel 3, and the solar energy absorbed by the photovoltaic panel 3 is stored through the storage battery 4; when the equipment needs power, the storage battery 4 discharges to ensure that the equipment can operate normally.

[0059] Furthermore, the detection component 6 includes an outer metal protective shell, and a temperature sensor and a pressure sensor disposed inside the metal protective shell; the temperature sensor can detect the stability of the water layer, and the pressure sensor can measure the underwater pressure to avoid damage to the sensor due to excessive water pressure.

[0060] The end of the detection component 6 is also connected to a wire, which is a waterproof wire; the waterproof wire ensures that the sensor transmits the underwater detection information to the water surface, so that the staff can understand the water temperature and water level.

[0061] It should be noted that the outer wall of the roller of the take-up and release component 5 is wound with a wire connected to the detection component 6. When it is necessary to adjust the position of the detection component 6, the take-up and release component 5 can be used to take up and release the wire of the detection component 6, thereby adjusting the position of the detection component 6.

[0062] Reference Figure 1 and Figure 3 In one embodiment provided in this application, the take-up and release member 5 includes a motor 51 installed inside the carrier member 1, a pulley 52 connected to the output end of the motor 51, and a take-up roller 53 driven by the pulley 52; the outer wall of the take-up roller 53 is wound with a wire connected to the detection member 6.

[0063] It should be noted that this device is driven by a motor 51, which drives the pulley 52 to rotate. During the rotation of the pulley 52, the winding roller 53 is driven to rotate, and the winding roller 53 is used to wind up the wire, thereby changing the height of the detection piece 6 in the river.

[0064] Specifically, in order to ensure that the wire can be evenly wound around the outside of the take-up roller 53, pulleys are installed on the wire take-up and unwinding path to ensure that the wire can be taken up and unwound smoothly; an encoder is also installed on the wire take-up and unwinding path to contact the wire; the encoder can accurately measure the length of the wire below, so that the staff can understand the water level depth of the detection piece 6, and ensure that the detection piece 6 can understand the water level height while detecting the water temperature.

[0065] Furthermore, a counterweight is provided at the bottom of the detection component 6, which enables the detection component 6 to move deeper into the water layer when the take-up roller 53 unwinds due to its own weight.

[0066] It should be noted that, in order to allow the detection element 6 to move to deeper water during the unwinding process of the take-up roller 53, a counterweight is provided at the bottom of the detection element 6, which moves the detection element 6 downward by its own weight. When the wire is wound up, the wire will pass through the sponge block set inside the bearing element 1. Through the compression of the sponge block, the sponge can absorb the water attached to the wire, thus preventing too much river water residue on the wire.

[0067] Furthermore, infrared detection modules 8 are installed at the four corners of the outer wall of the support component 1. The infrared detection modules 8 can detect obstacles in the river channel, making it easier for the support component 1 to avoid them.

[0068] The infrared detection module 8 is located at the four corners of the carrier 1. It can detect obstacles in the river channel during the movement of the carrier 1 and control the carrier 1 to avoid the obstacles in a reasonable manner.

[0069] Reference Figure 1 and Figure 6 In one embodiment provided in this application, a PLC control module is included, which is installed inside the carrier 1. The PLC control module is connected to a touch display panel via a line and is connected to the wire of the detection component 6. A wireless signal transmission module is connected to the PLC control module. A power propeller is installed at the bottom of the carrier 1 and is connected to the PLC control module.

[0070] It should be noted that the PLC control module is fixedly installed inside the carrier 1, and the PLC control module is connected to a touch display panel. The operation of the equipment can be controlled and corresponding adjustments can be made through the touch display panel. The temperature of the water layer and the depth of the water layer where the detection element 6 is located can be directly displayed through the touch display panel, making it convenient for staff to read the relevant information directly.

[0071] Furthermore, the device is also equipped with a wireless signal transmission module, which allows staff to remotely operate and control the device, thereby improving the convenience of their work.

[0072] Specifically, the take-up and unwinding component 5 is controlled by a PLC control module. The PLC control module can control the start and stop of the motor 51, which in turn drives the pulley 52 to rotate. The rotation of the pulley 52 in turn drives the take-up roller 53 to rotate. The take-up and unwinding of the wire can be completed by rotating the take-up roller 53.

[0073] Specifically, the photovoltaic panel 3 is connected to the PLC control module and the battery 4 via circuit connection lines. The battery 4 can store the electrical energy generated by the photovoltaic panel 3 and use it to provide continuous power supply for various parts of the pilot device during long-term field measurements. Especially under high light intensity, it can significantly enhance the device's endurance and avoid increasing the workload of monitoring personnel by repeatedly retrieving the device.

[0074] The wireless signal transmission module transmits water temperature measurement commands and directional points to the PLC control module by receiving signals. The PLC control module signals drive the propeller through the signal circuit connection line and the battery 4. The rotation of the propeller moves the device to the river for positioning.

[0075] After the device moves to the designated point on the river, it can issue a water temperature measurement task to the PLC control module according to the instructions specified by the wireless transmission module. This includes measuring the distance between water layers, the measurement time between each water layer, and the lowering and retrieval rate of the temperature probe. When the measurement task command is issued, the PLC control module transmits the information to the motor 51 through the signal transmission line. The motor 51 will drive the take-up roller 53 to lower the measuring component 6. When the required water layer is reached, the PLC control module can stop the rotation of the take-up roller 53. Then the temperature probe can measure the water temperature of the required water layer.

[0076] During the movement, the infrared detection module 8 can identify passing ships, islands and exposed reefs in the river. The signal is then transmitted to the PLC control module. After processing the signal, the PLC control module transmits instructions to the propeller to stop the device from moving, turn, or perform other operations, thus avoiding risks.

[0077] The wireless transmission function can measure water temperature and other data at different depths in a river section, providing more objective and comprehensive results compared to traditional single-point data measurement.

[0078] In summary, when conducting multi-point, multi-depth water temperature measurements at river cross-sections in the field, technicians can input the measurement plan and related data into the PLC control module via remote wireless signal transmission or manual settings. After completing the measurement parameter settings, the technicians place the device in the water. The device will move according to the given instructions, driven by a steering propeller to the designated point. During this process, the infrared detection module 8 will ensure that the device avoids obstacles in the river. When the device reaches the point, the measuring element 6 is lowered according to the measurement requirements. During this process, the encoder will transmit the diving depth of the measuring element 6 in real time. When the designated depth is reached, the motor 51 will stop rotating. Subsequently, the temperature probe will measure the water temperature at different depths. The data obtained will be transmitted to the wireless signal transmission module via a waterproof wire, which will then facilitate data processing and analysis by the terminal computer. After completing the water temperature measurement at different depths at this point, the device can issue instructions to the propeller via the PLC control module according to the given commands, ensuring that the device moves along a certain cross section to the next measurement point to carry out water temperature measurement. During this process, the photovoltaic panel 3 can continuously convert solar radiation into electrical energy to directly power the device or store it in the battery, increasing the device's endurance, avoiding the need for technicians to retrieve the device multiple times, and improving measurement efficiency.

[0079] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
