Description

Technical Field

[0001] This utility model relates to the field of water body detection technology, and in particular to a device for lowering a water body detector. Background Technology

[0002] A water quality analyzer is an instrument used to detect the concentration of various substances in water. It is an important instrument in environmental monitoring for quickly and accurately assessing water quality. During operation, the water quality analyzer needs to be slowly lowered into the water body. This process typically requires manual lowering by pulling on the instrument's cable. During lowering, the weight of the water sampler and the shear stress generated by swaying are borne by the cable connector. The axial stress on the cable connector may cause it to loosen, making it difficult to guarantee the reliability of the cable connection. Utility Model Content

[0003] This invention provides a water body detector lowering device to solve the problem in the prior art where, during the lowering of the water body detector, the cable joint bears the weight of the water body detector and the stress generated by swinging, which may loosen during long-term operation, making it difficult to guarantee the connection reliability of the cable joint.

[0004] This utility model provides a water quality analyzer lowering device, comprising: a base for fixing the water quality analyzer, the base having a cable hole and a cable interface therein, and the base also having a coupling component; a lowering cable, the first end of which has a cable connector coupled to the cable interface to fix the lowering cable to the base; and a flexible load-bearing sleeve fitted onto the lowering cable and connected to the coupling component via a connecting rope, wherein the lowering cable between the flexible load-bearing sleeve and the base is configured to be bent; wherein, when lowering the water quality analyzer, the connecting rope bears the tension on the water quality analyzer and transmits the tension to the flexible load-bearing sleeve.

[0005] According to the present invention, a lowering device is provided, wherein the coupling component includes a plurality of fixing ears distributed at equal angles along a circumference centered on the cable hole; the fixing ears include two support arms extending from the base in a first direction away from the water body detector, and a connecting arm connecting the ends of the two support arms; wherein the connecting rope is wound around the connecting arm to connect the flexible load-bearing sleeve and the fixing ears.

[0006] According to the present invention, a lowering device further includes a handle, comprising: two lifting arms extending from the base in the first direction, and a load-bearing arm connecting the ends of the two lifting arms.

[0007] According to the present invention, a lowering device is provided, wherein the support arm has a receiving hole, the radius of which is larger than the radius of the cable; wherein the cable passes through the receiving hole and is coupled to the cable hole.

[0008] According to the present invention, the contact surface between the flexible bearing sleeve and the lowering cable has a length along the extension direction of the lowering cable that is greater than or equal to 30 cm.

[0009] According to the present invention, a lowering device is provided in which the flexible load-bearing sleeve is a metal mesh cover woven from multiple steel wires in a spiral.

[0010] According to the present invention, a lowering device is provided in which the connecting rope is composed of a bundle of multiple steel wires in the metal mesh cover.

[0011] According to the present invention, a lowering device is provided in which the connecting rope and the metal mesh cover are separately arranged, and the end of the connecting rope near the metal mesh cover is a hook with a locking structure; wherein, the hook is hooked on the edge of the metal mesh cover and the locking structure is closed to fix the connecting rope and the metal mesh cover.

[0012] According to the present invention, the material of the metal mesh cover is 316 stainless steel.

[0013] According to the present invention, a lowering device is provided with a sealing gasket on the bottom surface of the base near the water body detector.

[0014] The water body detector lowering device provided by this utility model has a curved lowering cable between the flexible bearing sleeve and the base. Therefore, during the lowering process of the water body detector, the tension is mainly borne by the connecting rope, and the cable joint does not bear the stress applied by the water body detector. This ensures that the cable joint will not loosen due to excessive stress, thus guaranteeing the reliability of the cable joint.

[0015] One or more technical solutions of this utility model have at least the following technical effects or advantages:

[0016] (1) The flexible load-bearing sleeve can share the pressure on the cable joint, ensuring the reliability of the cable joint during the lowering process;

[0017] (2) The handle is provided with a receiving hole, which allows the lowered cable to be directly coupled to the cable hole, reducing the bending of the lowered cable and effectively improving the service life of the cable;

[0018] (3) Since the flexible load-bearing cover is installed on the lowering cable, the position of the flexible load-bearing cover can be reasonably selected according to the weight of the water body monitoring instrument. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] During the process of lowering the water body detector, the cable joints often bear the weight of the water body detector as well as the stress caused by the shaking of the water body detector, making it difficult to guarantee the reliability of the cable joint connection.

[0033] In view of this, an embodiment of the present invention provides a water body detector lowering device.

[0034] Figure 1 This is a schematic diagram of a water body detector lowering device according to an illustrative embodiment of the present invention.

[0035] like Figure 1 As shown, the water quality monitoring instrument lowering device includes a base 10, a lowering cable 20, a flexible support sleeve 30, and a connecting rope 31. The base 10 is used for fixed connection of the water quality monitoring instrument 40. The base 10 has a cable hole with a cable interface 11 inside, and a coupling component is also provided. The first end of the lowering cable 20 is equipped with a cable connector 21, which couples with the cable interface 11 to fix the lowering cable 20 to the base 10. The flexible support sleeve 30 is fitted onto the lowering cable 20 and connected to the coupling component 12 via the connecting rope 31. The lowering cable 20 between the flexible support sleeve 30 and the base 10 has an extra length; for example, the projection of the lowering cable 20 between the flexible support sleeve 30 and the base 10 in the vertical plane is 1 cm longer than that of the connecting rope 31, and therefore it is configured to be curved. When the water body detector 40 is lowered, the connecting rope 31 bears the tension of the water body detector and transmits the tension to the flexible load-bearing sleeve 30.

[0036] According to an embodiment of this utility model, the coupling part 12 can be a coupling hole opened on the base 10, through which the connecting rope 31 can pass and be knotted to fix the lowering cable 20 and the base 10. Alternatively, the coupling part 12 can be a metal ring provided on the base 10, through which the connecting rope 31 can be directly passed to complete the fixed connection to the base 10. The top surface of the base 10 is provided with a threaded hole, and one end of the connecting rope 31 used to connect to the base 10 is constructed as a ring, with the connecting rope 31 pressed onto the base 10 by the nut of a screw.

[0037] According to an embodiment of this utility model, the flexible load-bearing sleeve 30 can be a mesh sleeve woven from high-strength fibers such as aramid, nylon, and polyester, or it can be a steel wire rope braided sleeve.

[0038] The water body detector lowering device provided by the embodiments of this utility model has a curved lowering cable 20 between the base 10 and the flexible support sleeve 30. Therefore, the cable joint 21 is basically unstressed when the water body detector is lifted or lowered. When the water body detector is lifted or lowered, the corresponding force is transmitted to the flexible support sleeve 30 through the connecting rope 31, which causes the flexible support sleeve 30 to be tensile and contract. The gravity of the water body detector and the tangential stress caused by shaking are transformed into friction between the flexible support sleeve 30 and the lowering cable 20 through the connecting rope 31 and the flexible support sleeve 30. The axial stress that should have been borne by the fragile cable joint 21 is evenly distributed on a larger contact surface between the flexible support sleeve 30 and the lowering cable 20, which can effectively protect the cable joint 21 and ensure the connection effectiveness of the cable joint 21.

[0039] In one illustrative embodiment, the coupling part 12 includes a plurality of fixing ears distributed at equal angles along a circumference centered on the cable hole. Each fixing ear includes two support arms extending from the base 10 in a first direction away from the water quality detector, and a connecting arm connecting the ends of the two support arms. A connecting rope 31 is wound or sleeved around the connecting arm to connect the flexible load-bearing sleeve 30 and the fixing ears.

[0040] According to the embodiments of this utility model, since there are multiple fixing ears, the stress borne by the connecting rope 31 is distributed to multiple points, avoiding excessive stress concentration in the connecting rope 31. In addition, since the fixing ears are distributed at equal angles along the circumference with the cable hole as the center, it can be ensured that the central axis of the force is approximately coincident with the axis of the cable hole, which can suppress possible swaying during lifting or lowering.

[0041] According to an embodiment of the present invention, the fixing ear can be integrally formed with the base 10, which ensures the structural strength of the fixing ear.

[0042] According to an embodiment of the present invention, screw holes are provided on the side walls of the fixing ear and the base 10 respectively, and the fixing ear is fixed to the side wall of the base 10 by bolts.

[0043] In one illustrative embodiment, the lowering device further includes a handle 13, comprising two lifting arms extending from the base 10 in a first direction, and a load-bearing arm connecting the ends of the two lifting arms.

[0044] According to embodiments of this utility model, the water body detector can be lowered using the handle 13 before water body testing is conducted, facilitating transport. Furthermore, after water body testing, when the water body detector needs to be retrieved, it can be directly hooked up using the handle 13 for easy recovery.

[0045] In one illustrative embodiment, the support arm has a receiving hole with a radius larger than that of the cable. The cable passes through the receiving hole and couples with the cable hole.

[0046] According to an embodiment of the present invention, when there is a handle 13, the lowering cable 20 may be bent due to the handle 13. By setting a receiving hole, the lowering cable 20 can be allowed to pass directly through, which reduces the bending of the lowering cable 20 and can effectively improve the service life of the cable.

[0047] In one illustrative embodiment, the contact surface between the flexible support sleeve 30 and the lowering cable 20 is longer than or equal to 30 cm along the extension direction of the lowering cable 20, so as to ensure that there is sufficient contact area between the flexible support sleeve 30 and the lowering cable 20, so as to provide sufficient tension for the connecting rope 31.

[0048] In one illustrative embodiment, the flexible load-bearing sleeve 30 is a metal mesh cover woven from multiple steel wires in a spiral. Due to the strong characteristics of the metal mesh cover, the stress of the metal mesh cover can be adjusted when it is placed on the lowering cable 20, so that the metal mesh cover can be firmly attached to the lowering cable 20 without relative displacement.

[0049] In one illustrative embodiment, the connecting rope 31 is composed of a bundle of multiple steel wires within a metal mesh enclosure. Due to this arrangement, the connecting rope 31 is integrally formed with the metal mesh enclosure, ensuring overall structural strength.

[0050] In one illustrative embodiment, the connecting rope 31 is separate from the metal mesh cover, and the end of the connecting rope 31 near the metal mesh cover is a hook with a locking structure. The hook is attached to the edge of the metal mesh cover and closes the locking structure to fix the connecting rope 31 to the metal mesh cover.

[0051] According to the embodiments of this utility model, since the connecting rope 31 and the metal mesh cover are separate, connecting ropes 31 of different lengths and materials can be selected according to the situation.

[0052] In one illustrative embodiment, the metal mesh cover is made of 316 stainless steel.

[0053] In one illustrative embodiment, a sealing gasket is provided on the bottom surface of the base 10 near the water body detector 40. The sealing gasket effectively prevents external water from seeping in through the gap between the base 10 and the water body detector during water body detection.

[0054] In one illustrative embodiment, the base 10 and the water body detector 40 can be fixedly connected by a threaded connection, or screw holes can be provided on the base 10 and the water body detector 40 for fixed connection by screws, or a flange can be used for fixed connection.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
