The problem that the water temperature at different depths cannot be detected at any time is particularly prominent. The traditional thermometer measurement method usually requires manual placement of the thermometer at a specific position in the water for reading. Not only is the operation cumbersome, but also only the water temperature data at a single position can be obtained. For an area like a seawater bath with a large area and different depth changes, it is simply impossible to comprehensively reflect the true situation of the water temperature.

[0040] In addition, in the description of the present application, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0041] Referring to Figures 1 to 6 , which is the first embodiment of the present utility model, a water temperature measuring device for a seawater bath is proposed, which is used to measure the water temperature of seawater at different depths in the seawater bath. It includes a telescopic device 1, one end of the telescopic device 1 is arranged on the pool wall of the seawater bath; one end of the installation shell 2 is arranged at the extended end of the telescopic device 1. After the telescopic device 1 extends, the installation shell 2 is close to the bottom of the seawater bath; a temperature detector 3 is arranged inside the installation shell 2; a data transmission system is arranged on the telescopic device 1 and is electrically connected to the temperature detector 3; a display and control module is arranged on the telescopic device 1 and is electrically connected to the temperature detector 3.

[0042] In this embodiment, in order to solve the problem that the water temperature measuring device in the related technology can only obtain the temperature of seawater at a single depth, a water temperature measuring device for a seawater bath is designed, which includes a telescopic display and control module device, an installation shell 2, a temperature detector 3, a data transmission system, and a display and control module. First, one end of the telescopic device 1 is firmly installed on the pool wall of the seawater bath. One end of the installation shell 2 is tightly connected to the extended end of the telescopic device 1. When the telescopic device 1 gradually extends, the installation shell 2 can move towards the bottom of the seawater bath and finally approach the bottom. Such a design can ensure that the temperature detector 3 can accurately measure the water temperature of seawater at different depths. The temperature detector 3 is installed inside the installation shell 2. The temperature detector 3 selects a high-precision electronic sensor, which can quickly and sensitively sense the temperature change of seawater. The temperature detector 3 matches the internal space of the installation shell 2 and is firmly installed, and will not loosen or shift due to the flow of seawater or external vibration.

[0043] The data transmission system is arranged on the telescopic device 1 and is electrically connected to the temperature detector 3 through an electric wire. The data transmission system can transmit the water temperature data detected by the temperature detector 3 to the display and control module in real time. The data transmission system can adopt advanced wireless transmission technology to ensure the stability and efficiency of data transmission. The display and control module is also arranged on the telescopic device 1 and is electrically connected to the temperature detector 3 through an electric wire. The display and control module is equipped with a clear display screen, which can intuitively display the water temperature data detected by the temperature detector 3. At the same time, the display and control module is also provided with operation buttons, and users can control the water temperature measuring device through these buttons, such as starting measurement, stopping measurement, adjusting measurement accuracy, etc.

[0044] The advantage is that the telescopic device 1 can extend the installation shell 2 and the temperature detector 3 to different depths of the seawater bathing beach, ensuring that the temperature detector 3 can accurately measure the seawater temperature at each depth and providing accurate water temperature information for swimmers and beach managers. The data transmission system can transmit the water temperature data detected by the temperature detector 3 to the display and control module in real time, and users can view the current water temperature data at any time, which is convenient and fast. The display and control module is set on the telescopic device 1, and users can easily operate and control the water temperature measuring device on the shore without entering the seawater, improving the safety and convenience of operation.

[0045] Furthermore, the telescopic device 1 includes a first sleeve 101, and one end of the first sleeve 101 is arranged on the pool wall of the seawater bathing beach;

[0046] a second sleeve 102, which is slidably arranged inside the first sleeve 101; a sliding rod 103 is slidably arranged inside the second sleeve 102, and one end of the installation shell 2 is arranged at one end of the sliding rod 103.

[0047] In this embodiment, it includes the first sleeve 101, the second sleeve 102 and the sliding rod 103.

[0048] First, one end of the first sleeve 101 is firmly installed on the pool wall of the seawater bathing beach through fasteners 6 such as bolts. The inner diameter of the first sleeve 101 should be large enough to ensure that the second sleeve 102 can slide smoothly inside it. Then the second sleeve 102 is made. The outer diameter of the second sleeve 102 is slightly smaller than the inner diameter of the first sleeve 101, so that it can easily slide inside the first sleeve 101. When installing the second sleeve 102, one end of it is inserted into the first sleeve 101, and the axes of the two are kept coincident to achieve smooth sliding. Then the sliding rod 103 is made. The outer diameter of the sliding rod 103 is slightly smaller than the inner diameter of the second sleeve 102 so that it can freely slide inside the second sleeve 102. One end of the sliding rod 103 is connected to the installation shell 2, and the temperature detector 3 is placed inside the installation shell 2. When it is necessary to measure the seawater temperature at different depths, the position of the sliding rod 103 inside the second sleeve 102 and the position of the second sleeve 102 inside the first sleeve 101 can be adjusted to move the installation shell 2.

[0049] The advantage is that the telescopic device 1 composed of the first sleeve 101, the second sleeve 102 and the sliding rod 103 can achieve multi-stage telescoping, can flexibly adjust the length of the measuring device according to the different depth requirements of the seawater bathing beach, and ensure that the installation shell 2 can reach different depth positions for water temperature measurement.

[0050] Further, the first sleeve 101 has two first grooves 1011, and the first rack teeth 1012 are arranged in the first grooves 1011; the sliding rod 103 has two second grooves 1031, and the second rack teeth 1032 are arranged in the second grooves 1031. A gear 4 is further included, which is rotatably arranged at one end of the second sleeve 102 away from the temperature detector 3 and meshes with both the first rack teeth 1012 and the second rack teeth 1032. After the second sleeve 102 slides in the first sleeve 101, the gear 4 is driven by the first rack teeth 1012 to rotate, and the rotation of the gear 4 drives the sliding rod 103 to slide in the second sleeve 102.

[0051] In this embodiment, the size and module of the gear 4 are designed according to the first rack teeth 1012 of the first sleeve 101 and the second rack teeth 1032 of the sliding rod 103 to ensure good meshing. The gear 4 is installed at one end of the second sleeve 102 away from the temperature detector 3 through a rotating shaft. During installation, it is necessary to ensure that the gear 4 can rotate freely and the meshing positions with the first rack teeth 1012 and the second rack teeth 1032 are accurate. When the second sleeve 102 slides in the first sleeve 101, the first rack teeth 1012 on the first sleeve 101 will drive the gear 4 to rotate. Since the gear 4 is simultaneously meshed with the second rack teeth 1032 on the sliding rod 103, the rotation of the gear 4 will drive the sliding rod 103 to slide in the second sleeve 102.

[0052] When it is necessary to move the installation shell 2 towards the bottom of the seawater bathing pool, the second sleeve 102 is slid downward in the first sleeve 101. At this time, the first rack teeth 1012 on the first sleeve 101 will drive the gear 4 to rotate clockwise. The clockwise rotation of the gear 4 will drive the sliding rod 103 to slide downward in the second sleeve 102, so that the installation shell 2 gradually approaches the bottom of the pool. Conversely, when it is necessary to move the installation shell 2 upward, the second sleeve 102 is pulled upward to slide, the gear 4 rotates counterclockwise, and drives the sliding rod 103 to move upward.

[0053] The advantage is that through the meshing of the gear 4 with the first rack teeth 1012 and the second rack teeth 1032, the synchronous transmission of the second sleeve 102 and the sliding rod 103 is realized. When the second sleeve 102 slides in the first sleeve 101, it can automatically drive the sliding rod 103 to slide in the second sleeve 102 without additional operations, improving the usability of the measuring device. The gear 4 transmission has high precision, and can accurately control the sliding distance of the sliding rod 103 in the second sleeve 102, so as to accurately position the installation shell 2 at the required measuring depth position, improving the accuracy of water temperature measurement.

[0054] Further, one side of the second sleeve 102 has third rack teeth 1021. It further includes a rotating handle 5 which penetrates and is rotatably arranged on the first sleeve 101. One end of the rotating handle 5 located inside the first sleeve 101 has gear teeth 501 which mesh with the third rack teeth 1021. After the rotating handle 5 rotates, it drives the second sleeve 102 to slide inside the first sleeve 101.

[0055] In this embodiment, gear teeth 501 are machined at one end of the rotating handle 5. The size and module of the gear teeth 501 are designed according to the third rack teeth 1021 on one side of the second sleeve 102 to ensure good meshing between the two. The rotating handle 5 is penetrated and rotatably arranged on the first sleeve 101. A hole of a suitable size is opened on the first sleeve 101 so that the rotating handle 5 can pass through smoothly and be installed on the first sleeve 101. During installation, it is necessary to ensure that the rotating handle 5 can rotate freely and the gear teeth 501 mesh accurately with the third rack teeth 1021 on the second sleeve 102.

[0056] When the length of the telescopic device 1 needs to be adjusted, the operator holds the rotating handle 5 and rotates it. For example, when the rotating handle 5 is rotated clockwise, the gear teeth 501 on the rotating handle 5 drive the third rack teeth 1021 on the second sleeve 102, causing the second sleeve 102 to slide downward inside the first sleeve 101. As the second sleeve 102 slides, through the meshing transmission of the gear 4 with the first rack teeth 1012 and the second rack teeth 1032, the sliding rod 103 is driven to slide downward inside the second sleeve 102, thereby moving the mounting shell 2 towards the bottom of the seawater bathing pool. When the rotating handle 5 is rotated counterclockwise, the second sleeve 102 and the sliding rod 103 can be made to slide upward, moving the mounting shell 2 away from the bottom of the pool.

[0057] The advantage is that the setting of the rotating handle 5 enables the operator to easily adjust the length of the telescopic device 1 by manual rotation without the need to rely on complex mechanical structures or electrical equipment. The operation is simple and convenient, suitable for various occasions. Through the meshing transmission between the rotating handle 5 and the third rack teeth 1021 on the second sleeve 102, the sliding distance of the second sleeve 102 inside the first sleeve 101 can be precisely controlled, thereby realizing the precise adjustment of the length of the telescopic device 1 and ensuring that the mounting shell 2 can accurately reach the position of the required measurement depth.

[0058] Further, the first sleeve 101 has several mounting parts 1013. It further includes a fastener 6 which is arranged on the mounting parts 1013 and is used to limit the relative positions of the first sleeve 101 and the second sleeve 102.

[0059] In this embodiment, a number of mounting portions 1013 are provided on the first sleeve 101. The mounting portions 1013 may be structures such as threaded holes or card slots evenly distributed on the surface of the first sleeve 101. For example, four threaded holes are provided as the mounting portions 1013, which are located at different height positions of the first sleeve 101 respectively. The fastener 6 may be a bolt, a nut or a clamp, etc. If the mounting portion 1013 is a threaded hole, then the fastener 6 adopts a combination of a bolt and a nut. The bolt is passed through the threaded hole, and the fastening effect is achieved by rotating the nut.

[0060] When it is necessary to limit the relative position between the first sleeve 101 and the second sleeve 102, a suitable mounting portion 1013 is selected according to the actual situation, and the fastener 6 is installed at this position. For example, when the second sleeve 102 slides to a certain position within the first sleeve 101, so that the mounting shell 2 reaches the required measurement depth, a mounting portion 1013 close to the second sleeve 102 is selected, the bolt is passed through the threaded hole, and the nut is tightened so that the nut tightly presses on the surface of the second sleeve 102, thereby limiting the relative position between the first sleeve 101 and the second sleeve 102 and preventing accidental sliding of the telescopic device 1 during the measurement process.

[0061] The advantage is that the fastener 6 is connected to the first sleeve 101 through the mounting portion 1013, which can firmly limit the relative position between the first sleeve 101 and the second sleeve 102, ensuring that the telescopic device 1 will not slide due to factors such as the flow of seawater and external impacts during the measurement process, and guaranteeing the stability and accuracy of the measurement.

[0062] Due to the provision of a number of mounting portions 1013, according to different measurement requirements, a suitable mounting portion 1013 can be flexibly selected to install the fastener 6, so as to fix telescopic devices 1 of different lengths, improving the adaptability of the measurement device.

[0063] Furthermore, one end of the mounting shell 2 away from the telescopic device 1 has a water storage box 201, and the water storage box 201 has a number of water inlet holes 2011.

[0064] In this embodiment, the shape of the water storage box 201 can be designed as a cylinder or a cuboid, etc., for the convenience of installation and use. A number of water inlet holes 2011 are opened on the water storage box 201. The size and number of the water inlet holes 2011 should be reasonably designed according to actual needs. These water inlet holes can allow seawater to flow smoothly into the water storage box 201, enabling the temperature detector 3 to accurately detect the temperature of the seawater in the water storage box 201, thereby representing the seawater temperature at the corresponding depth.

[0065] The advantage is that the design of the water storage box 201 and the water inlet holes can enable the temperature detector 3 to detect a relatively stable seawater sample, avoiding the errors that may be brought about by directly measuring in flowing seawater and improving the accuracy of water temperature measurement. The multiple water inlet holes can enable seawater to flow into the water storage box 201 quickly, and the temperature detector 3 can quickly detect the temperature of the seawater entering the water storage box 201, improving the response speed of the measuring device.

[0066] Furthermore, the mounting shell 2 also has an observation window 202 for observing the state of the temperature detector 3.

[0067] In this embodiment, the observation window 202 can be made of a high-strength transparent material, such as an acrylic board or tempered glass. The shape of the observation window 202 can be designed according to the shape of the mounting shell 2, usually circular or rectangular. The observation window 202 is installed at a suitable position on the mounting shell 2 to ensure good sealing between the observation window 202 and the mounting shell 2 to prevent seawater from seeping in. After the temperature detector 3 is installed in the mounting shell 2, the state of the temperature detector 3 can be clearly seen through the observation window 202. For example, it can be observed whether the numbers on the display screen of the temperature detector 3 are normally displayed, or whether the indicator lights of the temperature detector 3 are working properly, etc.

[0068] In actual use, the operator can, without opening the mounting shell 2, understand the working state of the temperature detector 3 at any time through the observation window 202 so as to discover problems in time and handle them.

[0069] The advantage is that the setting of the observation window 202 enables the operator to directly observe the state of the temperature detector 3 without opening the mounting shell 2, which is convenient and fast. In this way, it can be known at any time whether the temperature detector 3 is working properly, improving the reliability of the measurement.

[0070] Furthermore, the temperature detector 3 coincides with the axis of the mounting shell 2.

[0071] In this embodiment, when installing the temperature detector 3, it is accurately placed on the central axis of the mounting shell 2 to ensure that the temperature detector 3 coincides with the axis of the mounting shell 2. During the installation process, measuring tools, such as calipers and spirit levels, are used to repeatedly check and adjust the position of the temperature detector 3 to ensure that the coincidence accuracy between it and the axis of the mounting shell 2 meets the requirements.

[0072] The advantage is that the coincidence of the temperature detector 3 with the axis of the mounting shell 2 can enable the temperature detector 3 to more evenly contact the surrounding seawater when measuring the seawater temperature, avoiding the influence of local temperature differences caused by position deviation on the measurement result and improving the accuracy of water temperature measurement.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
