Abstract
Description
Technical Field
[0001] This patent application belongs to the field of geological equipment technology, and more specifically, relates to a device for the smooth recovery of an electrical water level gauge measuring rod. Background Technology
[0002] Hydrogeological surveys in mines are an indispensable part of mine construction, and the observation of water levels in dewatering wells is a link in the study of mine hydrogeology. Electrical water level gauges are indispensable instruments for observing water levels.
[0003] Electrical water level gauges typically consist of a measuring scale, probe, reel, and crank. During the retrieval of the measuring scale, it can become stuck on the outside of the reel. This leads to both increased instrument wear and reduced operational efficiency. The main reason for this is that the measuring scale, being of a certain width, tends to stack along its lower position during retrieval. The thickness of the scale quickly exceeds the width of the reel, causing subsequent retrieved scales to fall off and become stuck on the outside of the reel, jamming against the support or crank.
[0004] The above situation often occurs in the practice of water level observation in precipitation wells, and organizing the measuring tape wastes a lot of time, which brings great inconvenience to water level observation. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a device for the smooth retrieval of the measuring rod of an electric water level gauge, so that the measuring rod of the electric water level gauge can be retrieved smoothly, which meets the requirements of geologists, achieves the effect of the instrument itself, and saves the time cost required to sort out the measuring rod when it is stuck on the outside of the winding reel.
[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:
[0007] A device for smoothly retrieving the measuring scale of an electrical water level gauge includes a bracket, a winding reel located in the middle of the bracket, a crank handle located on the winding reel, a housing located outside the winding reel, a measuring scale outlet located on the central axis of the winding reel and offset to one side of the central axis, a measuring scale wound on the winding reel and led out from the measuring scale outlet, and a measuring scale probe located at the end of the measuring scale. The measuring scale outlet is located on the housing; that is, the measuring scale is introduced from the winding reel.
[0008] The bracket includes an upper section, a middle section, and a lower section arranged from top to bottom. The winding reel is located on the middle section. The upper section is bent into a handle shape. The lower section has fixing holes with screws. The lower section is fixed to the electric water level gauge through the fixing holes and screws.
[0009] The distance between the outer casing and the winding reel is h. The distance h is the smallest at the upper section of the bracket and gradually increases from both sides. The two ends of the outer casing are fixed to the lower section.
[0010] Furthermore, the lower section consists of two L-shaped support legs, both of which are connected to the middle section. Each support leg has two fixing holes on both sides. Thus, there are a total of four fixing holes 4, located on both sides of the outer casing 9, for fixing the device to the electrical water level gauge.
[0011] Furthermore, the two fixing holes on each outrigger are located on the same horizontal line.
[0012] Furthermore, the crank handle is equipped with an anti-slip pad.
[0013] Furthermore, the measuring scale exit can be circular, elliptical, or square.
[0014] Furthermore, the upper section includes two vertical rods connected to the middle section, a diagonal rod connected to the vertical rods at an angle, and a horizontal rod connected to the end of the diagonal rod, with the diagonal rod facing the winding wheel.
[0015] Furthermore, the inclination angle between the diagonal bar and the vertical bar is 15°~30°.
[0016] The beneficial effects achieved by this utility model due to the adoption of the above technical solution are as follows:
[0017] This device has a simple structure, low manufacturing cost, and easily replaceable parts. It is used in the process of observing water levels in dewatering wells to solve the problem of jamming during the retrieval of measuring tapes. It avoids the problem that the thickness of the measuring tape quickly exceeds the width of the winding reel, causing the subsequently retrieved measuring tape to fall outside the winding reel and get stuck in the bracket, crank handle, etc. This greatly saves the time cost of using electric water level gauges, improves the work efficiency of geological personnel, and enables rapid completion of water level observation. In addition, the device is simple to operate, convenient, practical, and portable, reducing unnecessary handling processes. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the embodiments.
[0024] A device for the smooth retrieval of the measuring scale of an electrical water level gauge, such as Figures 1-4 It includes a bracket 3, a winding reel 1 located in the middle of the bracket 3, a crank handle 2 located on the winding reel 1, a housing 9 located outside the winding reel 1, a measuring scale outlet 6 located on the central axis of the winding reel 1 and biased towards one side of the central axis, a measuring scale 7 wound on the winding reel 1 and led out from the measuring scale outlet 6, and a measuring scale probe 8 located at the end of the measuring scale 7. The measuring scale outlet 6 is located on the housing 9, that is, the measuring scale 7 is introduced from the winding reel 1.
[0025] The bracket 3 includes an upper section, a middle section, and a lower section arranged from top to bottom. The winding wheel 1 is located on the middle section. The upper section is bent into a handle shape. The lower section is provided with a fixing hole 4, and the fixing hole 4 is equipped with a screw 5. The lower section is fixed to the electric water level gauge through the fixing hole 4 and the screw 5.
[0026] The distance between the outer casing 9 and the winding reel 1 is h. The distance h is the smallest at the upper section of the bracket 3 and gradually increases from both sides. The two ends of the outer casing 9 are fixed to the lower section.
[0027] The lower section consists of two L-shaped support legs, both of which connect to the middle section. Each support leg has two fixing holes 4 on both sides. There are a total of four fixing holes 4, located on both sides of the outer casing 9, for fixing the device to the electrical level gauge. The two ends of the outer casing 9 can also be fixed to the lower section via the fixing holes 4.
[0028] The two fixing holes 4 on each leg are located on the same horizontal line, the crank handle 2 is equipped with an anti-slip pad, and the measuring scale outlet 6 is round, oval or square.
[0029] The upper section includes two vertical rods connected to the middle section, diagonal rods correspondingly inclined to the vertical rods, and a horizontal rod connected to the end of the diagonal rods. The diagonal rods are positioned towards the winding reel 1. The inclination angle between the diagonal rods and the vertical rods is 15°~30°, for example, 25°.
[0030] This utility model involves fabricating a housing 9, with screws 5 fixed to a bracket 3 via fixing holes 4. The housing 9 is then mounted on an electrical water level gauge using screws 5. A measuring scale 7 is wound around a hollow reel 1, and the measuring scale 7 and its probe 8 pass through the measuring scale outlet 6. Figure 1 During the design and manufacturing process, an outer shell 9 is added to the outside of the winding reel 1. The measuring scale outlet 6 is located on the outer shell 9. The distance between the outer shell 9 and the winding reel 1 is h. The distance h is the smallest at the upper section of the bracket 3 and gradually increases from both sides. The two ends of the outer shell 9 are fixed to the lower section. Figure 1 As can be seen, the interval distance h is the smallest at the top and then gradually increases from the left and right sides.
[0031] The measuring scale 7 is first wound around the reel 1 and then extended from the measuring scale outlet 6 on the outer casing 9. The structure of the electrical water level gauge is similar to that of a measuring tape; the measuring scale 7 is wound between the reel 1 and the outer casing 9, and a measuring scale probe 8 is installed at the end of the measuring scale 7. The measuring scale probe 8 can be made of a rigid material or other material capable of indicating the probe. During water level observation, the measuring scale 7 is extended from the measuring scale outlet 6 and continuously lengthened to perform the measurement operation.
[0032] After the water level observation is completed, turn the crank 2 to retrieve the measuring scale 7. The gap between the winding wheel 1 and the outer casing 9 at the upper part of the bracket 3 is small or narrow. Therefore, this small or narrow gap at the upper part will prevent the measuring scale 7 from stacking to the outside of the winding wheel 1. Since the space above the electric water level gauge is limited, when it is stacked to the height of the winding wheel 1, it will be blocked by the outer casing 9, thus allowing the measuring scale 7 to be retrieved smoothly.
[0033] In summary, this device can be easily fixed to an electrical water level gauge, quickly completing the cable laying and winding process, improving the efficiency of hydrological observation, and demonstrating significant practical effects.
