Description

Technical Field

[0001] The present application relates to the technical field of dissolved oxygen meter equipment, and in particular to an instrument bracket for a dissolved oxygen meter. Background Art

[0002] Dissolved oxygen meter is a kind of equipment widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemistry, food and tap water, etc., which is used to continuously monitor the content of dissolved oxygen in the solution. The instrument adopts high-sensitivity sensor and high-precision AD conversion technology to achieve fast and accurate measurement. It also has data storage function, which can record and print out the measurement results at any time, and can be equipped with peripheral devices such as printer or microcomputer according to user requirements.

[0003] In the related art, a Chinese patent with announcement number CN204099836U discloses a dissolved oxygen meter sensor mounting bracket, the technical key points of which are: comprising a fixed mounting plate and a movable plate, the movable plate being movably mounted in the fixed mounting plate, the fixed mounting plate being mounted on the pool wall through a connecting piece, and the movable plate fastens the connecting rod of the sensor to the movable plate through a fastener.

[0004] The above device can only adjust the position of the sensor in the vertical direction, so the detection range of the sensor is small. When it is necessary to detect other positions in the pool, it is necessary to first remove the fixed installation plate and move the fixed installation plate to the top of the desired detection position, then complete the installation of the fixed installation plate, and then move the sensor down to the desired position for detection. Therefore, when it is necessary to change the detection point, the use process of the above device is relatively cumbersome. Utility Model Content

[0008] By adopting the above technical solution, the connecting rod is rotatably set on the vertical pole, and the sensor probe is set at the end of the connecting rod. Therefore, the position of the sensor probe can be adjusted by rotating the connecting rod, and then the connecting rod can be fixed to the vertical pole by a locking piece, so it is convenient to adjust the detection position of the sensor probe; in addition, the sensor probe is set at the end of the connecting rod, so the connecting rod can support the sensor probe, thereby reducing the pulling of the sensor probe caused by water fluctuations, reducing the possibility of loosening the connection between the sensor probe and the cable plug, and helping to ensure the normal use of the sensor probe.

[0020] By adopting the above technical solution, the cable can be installed in the threading hole, so as to protect the cable and help ensure the service life of the cable.

[0021] Optionally, a floating body is provided at one end of the connecting rod away from the vertical pole.

[0022] By adopting the above technical solution, the floating body floats on the liquid level surface, so that the sensing probe at the end of the connecting rod can be stabilized on the liquid level surface, thereby facilitating the detection of dissolved oxygen content.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-3 This application is described in further detail.

[0037] Example 1

[0038] The present application discloses a dissolved oxygen meter bracket, which is described by taking its application beside a pool as an example. Figure 1 The dissolved oxygen meter support includes a vertical pole 1, a connecting rod 2 and a locking piece. The vertical pole 1 and the connecting rod 2 are both round poles; the bottom end of the vertical pole 1 is set on the ground outside the pool, and the vertical pole 1 is set vertically. The connecting rod 2 is hinged to the top of the vertical pole 1, and the hinge axis of the connecting rod 2 is set horizontally. The end of the connecting rod 2 away from the vertical pole 1 is tilted downward, and the bottom end of the connecting rod 2 can extend into the pool; the bottom end of the connecting rod 2 is used to connect with the sensor probe 4, so the position of the sensor probe 4 can be adjusted by rotating the connecting rod 2.

[0039] The locking member is a locking bolt 3; an adjustment hole 21 is provided at the top of the connecting rod 2, and a threaded hole is provided at the top of the vertical pole 1. The locking bolt 3 is inserted into the adjustment hole 21 and the threaded hole in turn, and the end of the locking bolt 3 is threadedly connected to the threaded hole; therefore, after the connecting rod 2 is rotated to the desired position, the locking bolt 3 can be tightened to fix the connecting rod 2 and the vertical pole 1. In other embodiments, the locking member can also be a latch; first, the connecting rod 2 is rotated and connected to the vertical pole 1 through a rotating shaft, and then a plurality of plug holes for the plug to be inserted are provided at the top of the vertical pole 1, and the plurality of plug holes are arranged in a circular array, the plug is slidably arranged on the connecting rod 2, and the plug and the rotating shaft are arranged in parallel at intervals, and the plug is inserted into the plug hole to achieve the locking of the connecting rod 2 and the vertical pole 1.

[0040] Furthermore, a plurality of adjustment holes 21 are provided, and are evenly spaced at the top end of the connecting rod 2 along the length direction of the connecting rod 2. Thus, by inserting the locking bolt 3 into different adjustment holes 21, the rotation radius of the bottom end of the connecting rod 2 can be adjusted, thereby further expanding the adjustment range.

[0041] The bracket also includes a mounting seat 5, which includes a base plate 51 and a sleeve 52. The base plate 51 is arranged horizontally and fixedly connected to the ground; the base plate 51 and the ground can be fixedly connected by anchor bolts, or embedded parts can be buried in the ground and then fixedly connected by bolts. The sleeve 52 is a cylinder, which is arranged vertically, and the bottom end of the sleeve 52 is welded to the top surface of the base plate 51. The bottom end of the vertical pole 1 is inserted into the inside of the sleeve 52, the diameter of the vertical pole 1 is adapted to the inner diameter of the sleeve 52, and the vertical pole 1 and the sleeve 52 are clearance-matched; therefore, the vertical pole 1 can rotate along the vertical axis relative to the sleeve 52, and the vertical pole 1 can also slide in the vertical direction relative to the sleeve 52, thereby expanding the adjustment range of the position of the sensor probe 4 at the end of the connecting rod 2. After the position of the vertical pole 1 is adjusted, the vertical pole 1 can be fixed at the current position by the friction between the vertical pole 1 and the sleeve 52.

[0042] Among them, an external support frame 8 is welded between the top surface of the base plate 51 and the outer wall of the sleeve 52. The external support frame 8 is inclined and arranged around the circumference of the sleeve 52 and in a circular array. The external support frame 8 can enhance the connection strength between the sleeve 52 and the base plate 51, which helps to enhance the stability of the bracket.

[0043] An operating handle 6 is also provided on the side wall of the vertical pole 1, and the length direction of the operating handle 6 is perpendicular to the axis of the vertical pole 1, so it is more labor-saving to rotate the vertical pole 1 while holding the operating handle 6. In addition, one end of the operating handle 6 is hinged to the vertical pole 1, and the hinge axis of the operating handle 6 is parallel to the hinge axis of the connecting rod 2, so the occupied space can be reduced after the operating handle 6 is rotated to a vertical state.

[0044] In order to facilitate the stable measurement of the sensor probe 4, a floating body 7 is hinged at one end of the connecting rod 2 away from the vertical rod 1, and the hinge axis of the floating body 7 is parallel to the hinge axis of the connecting rod 2. In this embodiment, the floating body 7 is a hollow floating plate; in other embodiments, the floating body 7 can also be block-shaped, ring-shaped or spherical, and the floating body 7 can also be made of a material with a lower density, such as wood. The detection end of the sensor probe 4 is located on the side of the floating body 7 away from the connecting rod 2, so that during detection, the floating body 7 floats on the liquid surface, so that the sensor probe 4 can be extended into the water to detect the dissolved oxygen content.

[0045] In order to protect the cable, the vertical pole 1 and the connecting rod 2 are both hollow tube-shaped, and the vertical pole 1 and the connecting rod 2 are provided with threading holes for the cable to pass in or out. One end of the cable is connected to the sensor probe 4, and the end of the cable away from the sensor probe 4 passes through the threading hole into the connecting rod 2 and the vertical pole 1, and then passes out from the bottom end of the vertical pole 1. The cable passing through the vertical pole 1 is connected to the dissolved oxygen meter body, and the dissolved oxygen meter body is placed on the ground. Both ends of the cable are located outside the threading hole, and the two ends of the cable are tied and fixed to the end of the vertical pole 1 and the end of the connecting rod 2 respectively, so that the vertical pole 1 and the connecting rod 2 can support the cable, thereby ensuring the stability of the cable.

[0046] The implementation principle of Example 1 is as follows: first, the sensing probe 4 is fixedly connected to the end of the connecting rod 2 away from the vertical pole 1, then the cable connection is completed, and the main part of the cable is inserted into the connecting rod 2 and the vertical pole 1. Then, the mounting seat 5 is fixed on the ground, and then the operating handle 6 is held to rotate the vertical pole 1 around the vertical axis to the desired position. Then, the locking bolt 3 is inserted into the adjustment hole 21 and the threaded hole, and the connecting rod 2 will rotate downward under the gravity of the end sensing probe 4 until the floating body 7 floats on the water surface and the detection end of the sensing probe 4 extends into the water; at this time, tighten the locking bolt 3, fix the connecting rod 2 on the vertical pole 1, and the dissolved oxygen content can be detected. When the detection point needs to be changed, just loosen the locking bolt 3, then rotate the connecting rod 2, adjust the angle between the connecting rod 2 and the vertical pole 1, and then tighten the locking bolt 3.

[0047] Example 2

[0048] Reference Figure 2 The difference between this embodiment and the first embodiment is that the vertical rod 1 in this embodiment is a telescopic rod, and the vertical rod 1 includes a first rod body 12 and a second rod body 13, both of which are hollow cylindrical, and the first rod body 12 and the second rod body 13 are coaxially arranged; there are two first rod bodies 12, and the second rod body 13 is connected between the two first rod bodies 12. The ends of the two first rod bodies 12 close to each other are both provided with external threads, and both ends of the second rod body 13 are both provided with internal threads, and the two first rod bodies 12 are respectively threadedly connected to the two ends of the second rod body 13. Therefore, by rotating the second rod body 13, the distance between the two first rod bodies 12 can be adjusted, thereby realizing the adjustment of the length of the vertical rod 1, and further expanding the adjustment range of the position of the sensor probe 4.

[0049] Example 3

[0050] Reference Figure 3, the difference between this embodiment and embodiment 1 is that a fixing assembly 9 is provided on the sleeve 52 in this embodiment, and the fixing assembly 9 includes an insertion rod 91 and a spring 92. A mounting hole is provided on the outer wall of the sleeve 52, and the axis of the mounting hole is arranged along the radial direction of the sleeve 52; the insertion rod 91 is slidably inserted into the mounting hole. Correspondingly, a slot 11 is provided on the side wall at the bottom end of the vertical pole 1, and a plurality of slots 11 are provided and arranged in a circular array. The spring 92 is connected between one end of the insertion rod 91 located outside the sleeve 52 and the outer wall of the sleeve 52, and the spring 92 is in a stretched state. When the vertical pole 1 is rotated so that the insertion rod 91 and the slot 11 are on the same straight line, the spring 92 causes the end of the insertion rod 91 to be inserted into the slot 11, thereby limiting the rotation of the vertical pole 1 and fixing the vertical pole 1 at the current position, which can improve the stability of the vertical pole 1 during the detection process.

[0051] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
