[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 As shown, a hydrological level gauge installation sleeve includes: a cylinder 1 and a level gauge disposed inside the cylinder 1. The level gauge is a pressure level gauge in the prior art, which can be purchased directly. The level gauge is provided with a connecting line 2. It also includes: a top cover 3 disposed above the cylinder 1, through which the connecting line 2 passes; a lifting rod 4 disposed above the top cover 3, which is fixedly connected to the cylinder 1; a fastening mechanism 5 slidably connected to the top cover 3, with the top of the fastening mechanism 5 slidably connected to the lifting rod 4; a water filtering mechanism 6 disposed below the cylinder 1; and an auxiliary component 7 disposed on the side wall of the cylinder 1.

[0027] like Figure 2 , 3As shown, a support ring 11 is provided on the inner wall of the cylinder 1. The support ring 11 has a hole in the middle to facilitate the normal operation of the water level gauge. The bottom surface of the top cover 3 contacts the support ring 11, and the support ring 11 restricts the downward sliding of the top cover 3. When the top cover 3 contacts the support ring 11, the top surface of the top cover 3 and the top surface of the cylinder 1 are at the same horizontal plane. The side wall of the top cover 3 fits against the inner wall of the cylinder 1 to prevent mud and sand from entering the cylinder 1 from the top and affecting the accuracy of water level measurement. The top cover 3 is designed to be detachable to facilitate the maintenance of the water level gauge inside the cylinder 1.

[0028] The top cover 3 is provided with a cable outlet tube 31, and the cable outlet tube 31 is provided with a rubber ring 311. The connecting wire 2 passes through the rubber ring 311, and the rubber ring 311 fits the connecting wire 2. The rubber ring 311 is made of elastic material, which can ensure that the connecting wire 2 remains in contact with the connecting wire 2 when it moves, thereby increasing the sealing performance and ensuring the normal shaking of the connecting wire 2.

[0029] The lifting rod 4 has vertical rods on both sides and a horizontal rod in the middle. The vertical rods are fixed to the top of the cylinder 1. The lifting rod 4 has a limiting rail 41 on its upper side. The limiting rail 41 is a rectangular groove. The top of the lifting rod 4 also has two equipment holes 42. The inner wall of the equipment holes 42 is threaded. Bolts 421 can be screwed into the equipment holes 42. After the bolts 421 are screwed into the equipment holes 42, the equipment holes 42 are sealed.

[0030] The top cover 3 is provided with a slide rail 32, which is a convex groove. The slide rail 32 is located below the limiting rail 41, and the fastening mechanism 5 moves between the slide rail 32 and the limiting rail 41.

[0031] like Figure 4As shown, the fastening mechanism 5 includes a slider 51, a spring 52, a sliding sleeve 53, and a support column 54. The bottom of the slider 51 is convex and is slidably connected to the slide rail 32. The slide rail 32 restricts the movement trajectory of the slider 51. The sliding sleeve 53 is slidably connected to the upper part of the slider 51. The upper part of the slider 51 can enter the lower part of the sliding sleeve 53. The spring 52 connects the top of the slider 51 and the inner wall of the sliding sleeve 53. When the spring 52 is in a compressed state, it pushes the slider 51 downward, thereby causing the slider 51 to push the top cover 3, preventing the top cover 3 from falling off during water level measurement, thus protecting the water level gauge. The top of the sliding sleeve 53 is provided with a through hole 531 for placing the support column 54. The bottom of the support column 54 can be inserted into the through hole 531. The top of the support column 54 is slidably connected to the limiting rail 41 under the pushing force of the spring 52. The support column 54 can pass through the equipment hole 42. When closing the top cover 3, press down the sliding sleeve 53 and the support column 54 so that the top of the support column 54 enters the limiting rail 41, thereby preventing the top cover 3 from moving. When disassembling the top cover 3, the spring 52 may not be able to continue pressing down due to excessive force. At this time, the bolt 421 can be unscrewed to expose the equipment hole 42. Then, move the fastening mechanism 5 to move the support column 54 below the equipment hole 42. Under the pushing force of the spring 52, the support column 54 passes through the equipment hole 42. At this time, the support column 54 can be removed. Then, lift the slider 51 to remove the top cover 3.

[0032] like Figure 5 As shown, the water filtration mechanism 6 includes a water filtration disc 61, filter paper 62, water baffle column 63, filter curtain 64, and base 65. The water filtration disc 61 is provided with filter holes 611, which are distributed in a ring array at the bottom of the water filtration disc 61. The filter paper 62 is located above the filter holes 611. The water baffle column 63 is located below the water filtration disc 61 and is located inside the ring of filter holes 611. The filter curtain 64 is also located below the water filtration disc 61 and is located outside the ring of filter holes 611. The filter holes 611 are located between the water baffle column 63 and the filter curtain 64. The base 65 is detachably connected to the water baffle column 63.

[0033] The filter curtain 64 has many gaps, which can block large particles of garbage from entering. Water passes through the filter holes 611 and filter paper 62 through the filter curtain 64, thereby intercepting small particles of mud and sand, so that the content of water, sand and other impurities entering the cylinder 1 is small.

[0034] A compaction ring 12 is provided on the inner wall of the cylinder 1. The compaction ring 12 is annular in shape, and its diameter is smaller than that of the cylinder 1. The upper part of the compaction ring 12 is fixedly connected to the inner wall of the cylinder 1. The filter disc 61 is screwed to the cylinder 1. After the filter disc 61 is installed, the compaction ring 12 contacts the filter paper 62, thereby fixing the filter paper 62 and preventing it from being displaced by water pressure. The filter paper 62 should be replaced periodically after 2-3 uses to ensure filtration efficiency.

[0035] The bottom of the water-blocking column 63 is equipped with a threaded rod 631, which passes through the base 65. A limiting nut 632 is screwed onto the threaded rod 631, fixing the position of the base 65 so that it contacts the bottom surface of the filter curtain 64. When cleaning the water filtration mechanism 6, the base 65 can be removed for easy removal of internal debris. The water filtration mechanism 6 should be cleaned of debris and treated with rust prevention every 2-3 uses.

[0036] The auxiliary component 7 is designed to protect the cylinder 1 from impacts during well logging. The auxiliary component 7 includes a connecting ring 71 and rollers 72. The connecting ring 71 is fixed to the side wall of the cylinder 1, and the rollers 72 are arranged in a ring on the side wall of the connecting ring 71. When the device shakes, the rollers 72 come into contact with the inner wall of the well logging, and the rollers 72 can also assist the device in moving.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
