Description

A device for measuring radioactivity in drinking water Technical Field

[0001] This utility model relates to the field of detection equipment technology, and in particular to a device for measuring radioactivity in drinking water. Background Technology

[0002] Drinking water refers to water that can be directly consumed by humans and whose quality meets national health standards. Its sources include surface water such as rivers and lakes, as well as groundwater. It needs to undergo treatment processes such as sedimentation, filtration, and disinfection to meet standards for microbiology, toxicology, sensory properties, and general chemical indicators. It plays a key role in maintaining life, promoting human metabolism, digestion and absorption, blood circulation, and protecting health.

[0003] When the radioactivity level in drinking water exceeds national standards, it poses serious health risks. Long-term consumption of radioactively contaminated water may cause gene mutations, increase the risk of cancer, and damage the hematopoietic and immune systems. Simultaneously, it also negatively impacts the ecological environment, disrupting the survival and reproduction of aquatic organisms. Therefore, monitoring the radioactivity of drinking water is extremely important. Currently, portable testing pens are commonly used to measure the radioactivity level of drinking water. These pens have a detection head at the end; when in use, simply immersing the detection head in water displays the radioactivity level of the drinking water.

[0004] These types of testing pens typically have a detachable cap at the end to protect the testing head and prevent it from becoming contaminated, which could reduce testing accuracy. However, because the testing pen and cap are detachable, operators often lose the cap after using the pen, thus compromising the protection of the testing head. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide a device for measuring radioactivity in drinking water, which solves the problem mentioned in the background art that, since the detection pen and the cap are detachable, operators often lose the cap after using the detection pen.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] A device for measuring radioactivity in drinking water, comprising:

[0008] The body has mounting holes at its ends;

[0009] A cover, which is hinged to the mounting hole of the body and is capable of sealing the open end of the mounting hole;

[0010] A detection head, movably mounted to the mounting hole along the length of the body, and the end of the detection head being movable outside the mounting hole; and

[0011] A drive mechanism is mounted on the main body and is used to drive the detection head to move.

[0012] With the above technical solution, when using this device to detect radioactivity in drinking water, the detection head can be moved directly to the outside of the mounting hole via the drive mechanism. During movement, the detection head will open the cap, allowing it to smoothly move to the outside of the mounting hole. Then, one end of the detection head can be directly immersed in the drinking water for testing. After testing, the detection head can be moved back into the mounting hole via the drive mechanism, and the cap can be moved to seal the open end of the mounting hole. This design not only provides better protection for the detection head but also prevents the cap from being lost.

[0013] In one possible implementation, the detection head is provided with a guide slider, and the body has a guide groove on the inner wall of the mounting hole. The guide groove extends along the length of the body, and the guide slider is slidably installed in the guide groove.

[0014] Through the above technical solution, the cooperation between the guide slider and the guide groove allows the detection head to be movably installed into the mounting hole along the length of the body, facilitating the entry and exit of the detection head from the mounting hole.

[0015] In one possible implementation, the body is provided with a first hinge seat at the mounting hole, the cover is provided with a second hinge seat, and a pin connects the second hinge seat and the first hinge seat.

[0016] Through the above technical solution, the first hinge seat, the second hinge seat and the pin cooperate with each other to enable the cover to be hinged to the body, which facilitates the installation of the cover.

[0017] In one possible implementation, an elastic element is installed between the first hinge seat and the second hinge seat, and under the elastic force of the elastic element, the cover is in a state of sealing the open end of the mounting hole.

[0018] With the above technical solution, when the detection head enters the mounting hole from the outside, the cover can automatically seal the open end of the mounting hole under the elastic force of the elastic element, thereby improving the automation level of the device.

[0019] In one possible implementation, the elastic element is a torsion spring, which is sleeved on the pin, and the two torsion arms are respectively connected to the first hinge seat and the second hinge seat.

[0020] Through the above technical solution, under the elastic force of the torsion spring, the cover can automatically seal the open end of the mounting hole.

[0021] In one possible implementation, the drive mechanism includes a threaded sleeve, a threaded rod, a gear, and an annular rack;

[0022] The threaded sleeve is installed at the end of the detection head away from the cover;

[0023] The threaded rod is rotatably mounted in the body, with one end extending into the threaded sleeve and threadedly connected to the threaded sleeve.

[0024] The gear is mounted on the threaded rod, and at least part of the structure is located outside the body;

[0025] The annular rack is rotatably mounted axially on the surface of the body and meshes with the gear.

[0026] With the above technical solution, when the annular rack rotates, it can drive the gear to rotate, and then drive the threaded rod to rotate. Since the threaded rod is threadedly connected to the threaded sleeve, when the threaded rod rotates, the threaded sleeve can move axially, thereby driving the detection head to move along the length of the body, so that the detection head can enter and exit the mounting hole.

[0027] In one possible implementation, the inner ring of the annular rack is provided with an annular flange, and the surface of the body is provided with an annular groove adapted to the annular flange. The annular flange is installed in the annular groove and is rotatable along the axial direction.

[0028] Through the above technical solution, the annular flange and the annular groove cooperate to enable the annular rack to rotate axially on the body.

[0029] In one possible implementation, the outer ring of the annular toothed rack is provided with anti-slip texture.

[0030] The above technical solution, by setting anti-slip texture, makes it easier for users to rotate the annular rack.

[0031] The beneficial effects of this utility model are:

[0032] 1. By adopting the technical solution of this application, when using this device to detect radioactivity in drinking water, the detection head can be directly moved to the outside of the mounting hole via the drive mechanism. During movement, the detection head can open the cap, allowing it to move smoothly to the outside of the mounting hole. Then, one end of the detection head can be directly placed into the drinking water for testing. After testing, the detection head can be moved back into the mounting hole via the drive mechanism, and the cap can be moved to seal the open end of the mounting hole. This design not only provides better protection for the detection head but also prevents the cap from being lost.

[0033] 2. By adopting the technical solution of this application, the detection head can be movably installed into the mounting hole along the length direction of the body through the cooperation of the guide slider and the guide groove, which facilitates the entry and exit of the detection head into the mounting hole.

[0051] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0052] As shown in Figures 1-3, this application provides a device for measuring radioactivity in drinking water, including a main body 100, a cover 200, a detection head 300, and a driving mechanism. The main body 100 also includes a chip, a display screen, a battery, buttons, etc. The structure and principle of these components and the detection head 300 are existing technologies and will not be described in detail in this embodiment.

[0053] The body 100 has a mounting hole 110 at one end. A cover 200 is hinged to the mounting hole 110 of the body 100 and can cover the open end of the mounting hole 110. A detection head 300 is movably mounted to the mounting hole 110 along the length of the body 100, and the end of the detection head 300 can move outside the mounting hole 110. A drive mechanism is mounted on the body 100 for driving the movement of the detection head 300.

[0054] With the above technical solution, when using this device to detect radioactivity in drinking water, the detection head 300 can be directly moved to the outside of the mounting hole 110 via the drive mechanism. During this movement, the detection head 300 can push open the cover 200, allowing it to smoothly move to the outside of the mounting hole 110. Then, one end of the detection head 300 can be directly placed into the drinking water for testing. After testing, the detection head 300 can be moved back into the mounting hole 110 via the drive mechanism, and the cover 200 can be moved to seal the open end of the mounting hole 110. This design not only provides better protection for the detection head 300 but also prevents the cover 200 from being lost.

[0055] In one possible embodiment, the detection head 300 is provided with a guide slider 310, and the body 100 has a guide groove 120 on the inner wall of the mounting hole 110. The guide groove 120 extends along the length direction of the body 100, and the guide slider 310 is slidably installed in the guide groove 120. Through the cooperation of the guide slider 310 and the guide groove 120, the detection head 300 can be movably installed into the mounting hole 110 along the length direction of the body 100, facilitating the entry and exit of the detection head 300 from the mounting hole 110.

[0056] In one possible embodiment, the body 100 is provided with a first hinge seat 130 at the mounting hole 110, and the cover 200 is provided with a second hinge seat 210. A pin connects the second hinge seat 210 and the first hinge seat 130. Through the mutual cooperation of the first hinge seat 130, the second hinge seat 210 and the pin, the cover 200 can be hinged to the body 100, which facilitates the installation of the cover 200.

[0057] In one possible embodiment, an elastic element is installed between the first hinge seat 130 and the second hinge seat 210. Under the elastic force of the elastic element, the cover 200 is in a state of sealing the open end of the mounting hole 110. With this configuration, when the detection head 300 enters the mounting hole 110 from the outside, the cover 200 can automatically seal the open end of the mounting hole 110 under the elastic force of the elastic element, thereby improving the automation level of the device.

[0058] Specifically, the elastic element can be a coil spring, a torsion spring, etc. In this embodiment, the elastic element is preferably a torsion spring, which is sleeved on the pin, and the two torsion arms respectively abut against the first hinge seat 130 and the second hinge seat 210. Under the elastic force of the torsion spring, the cover 200 can automatically seal the open end of the mounting hole 110.

[0059] In one possible embodiment, the drive mechanism includes a threaded sleeve 410, a threaded rod 420, a gear 430, and an annular rack 440. The threaded sleeve 410 is fixedly mounted to the end of the detection head 300 away from the cover 200. The threaded rod 420 is rotatably mounted within the body 100 via a bearing, with one end extending into and threadedly connected to the threaded sleeve 410. The gear 430 is keyed to the threaded rod 420, with its main structure installed inside the body and at least a portion located outside the body 100, which has a hole for mounting the gear 430. The annular rack 440 is rotatably mounted axially on the surface of the body 100, with its inner ring having a rack, and meshes with the gear 430.

[0060] With the above technical solution, when the annular rack 440 rotates, it can drive the gear 430 to rotate, and then drive the threaded rod 420 to rotate. Since the threaded rod 420 is threadedly connected to the threaded sleeve 410, when the threaded rod 420 rotates, the threaded sleeve 410 can move axially, thereby driving the detection head 300 to move along the length direction of the body 100, so that the detection head 300 can enter and exit the mounting hole 110.

[0061] In this embodiment, the inner ring of the annular rack 440 is provided with an annular flange 441, and the outer surface of the body 100 is provided with an annular groove 140 adapted to the annular flange 441. The annular flange 441 is installed in the annular groove 140 and can rotate axially. Through the mutual cooperation of the annular flange 441 and the annular groove 140, the annular rack 440 can rotate axially on the body 100.

[0062] In this embodiment, the outer ring of the annular rack 440 is provided with anti-slip texture 442. By providing anti-slip texture 442, it is convenient for the user to rotate the annular rack 440.

[0063] In another embodiment, the drive mechanism can also be electrically driven. For example, the drive mechanism includes a threaded sleeve 410, a threaded rod 420, and a motor. The threaded sleeve 410 and threaded rod 420 are installed in the same way as in the above embodiment. The motor is installed inside the body 100, and the motor's output shaft is fixedly connected to one end of the threaded rod 420. The motor can directly drive the threaded rod 420 to rotate, and then drive the detection head 300 to move through the sleeve.
