Description

Technical Field

[0001] The utility model relates to the technical field of water level observation, in particular to an integrated stainless steel seepage pressure protection box. Background Art

[0002] At present, the methods commonly used for groundwater level observation in China can be divided into burying pressure measuring tubes in permeable layers and conducting observations with special groundwater observation instruments. The disadvantages of pressure measuring tubes are that they are easily damaged by human beings and affected by rainfall. At the same time, there are problems such as clogging by solid and chemical sediments, which makes long-term monitoring time-consuming and labor-intensive, and has a long lag time. Observation wells have the disadvantages of high manpower and time costs. Although automatic monitoring wells have the advantages of high efficiency, accuracy and low cost, they have the disadvantages of high equipment cost and equipment failure.

[0003] The utility model, with publication number CN221198577U, proposes a field water quality pressure hole protection box, comprising a trapezoidal base, a protection box mounted on the trapezoidal base, and a pressure measuring tube extending therethrough; an L-shaped straight tube mounted on the protection box; a rain shield mounted on the top of the protection box; a hook and a support shaft mounted on the inner wall of the protection box; a data acquisition device mounted on the hook, the data acquisition device being connected to an upper signal transmission line and a lower signal transmission line, respectively; a reel mounted on the support shaft; the lower signal transmission line wound around the reel, its free end extending into the pressure measuring tube and connected to an osmometer; the osmometer being located within the pressure measuring tube; a retaining edge fixed to one end of the reel; a dumbbell-shaped connecting column hingedly mounted on the retaining edge; a sleeve mounted in the middle of the connecting column; and a strip groove formed on the inner wall of the protection box, corresponding to the end of the connecting column. The utility model, through the protection box, protects the equipment from being easily damaged by human intervention and malfunctioning due to rainfall. The utility model is inexpensive, safe, and stable, and can be operated in conjunction with an osmometer, saving time and effort.

[0004] However, the above-mentioned existing technology still has the following shortcomings when used: the reel releases the piezometer to the depth of the pressure measuring tube by releasing the lower signal transmission line. Since the pressure measuring tube is deep, when the piezometer descends to a certain depth under the suspension of the lower signal transmission line, the weight of the lower signal transmission line located in the pressure measuring tube increases, and thus the load on the part of the lower signal transmission line close to the reel increases, which can easily cause the lower signal transmission line to crack or even break when the rotating shaft is frequently controlled to start and stop.

[0005] To this end, the utility model provides an integrated stainless steel seepage pressure protection box. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated stainless steel osmotic pressure protection box to solve the problems raised in the above-mentioned background technology. The utility model has the function of lifting and lowering buffering of the lower signal transmission line in the pressure measuring tube, thereby avoiding the problem of breakage of the lower signal transmission line and ensuring reliable monitoring of the piezometer.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 3 The utility model provides a technical solution: an integrated stainless steel seepage pressure protection box, comprising a stainless steel box body 1 and a winding roller 2 located in the stainless steel box body 1, and a data acquisition instrument and other related components for analyzing monitoring data are installed in the stainless steel box body 1. That is to say, the stainless steel box body 1 is used to support and protect the related components for monitoring the water body of the groundwater layer. The components for monitoring the water body of the groundwater layer can adopt the structure in the patent document mentioned in the background technology. This technical solution will not be described in detail. A pressure measuring tube 3 is provided at the bottom of the stainless steel box body 1, and the pressure measuring tube 3 can be fastened to the stainless steel box body 1 by screwing, the purpose is to facilitate disassembly and assembly. The pressure measuring tube 3 is a protective tube for the piezometer and the lower signal transmission line. When in use, the lower signal transmission line suspends the piezometer and descends in the pressure measuring tube 3, so that the piezometer descends to the water layer.

[0024] In this technical solution, a hanger 4 is elastically and slidably connected up and down inside the stainless steel box 1. In specific implementation, it is preferred that a hanging plate 11 is welded on the rear wall inside the stainless steel box 1, and a guide sleeve 111 is welded at the front end of the hanging plate 11 and is sleeved on the outside of the hanger 4. A baffle 41 is welded on the top of the hanger 4, and a buffer spring 101 is sleeved on the hanger 4 and is located between the baffle 41 and the guide sleeve 111. The buffer spring 101 provides buffering elastic force to the up and down impact action of the hanger 4. The bottom of the boom 4 is fixedly connected to a positioning plate 5, and a reversing pulley 6 is provided at the bottom of the positioning plate 5. The winding roller 2 and the pressure measuring tube 3 are located on both sides of the axis of the boom 4. The lower signal transmission line is wound on the winding roller 2, and one end of the lower signal transmission line passes around the reversing pulley 6 and extends downward into the pressure measuring tube 3, wherein one end of the lower signal transmission line is installed with an osmometer. When the lower signal transmission line is released, it carries the installed osmometer and descends in the pressure measuring tube 3. When it reaches the depth of the osmometer, the winding roller 2 will rotate forward and backward. The traction impact force generated by the start and stop of the winding roller 2 will be buffered by the up and down elastic movement of the boom 4, thereby effectively avoiding the problem of damage to the taut lower signal transmission line.

[0025] Furthermore, a worm gear 7 is fixedly provided on the winding roller 2, and a control motor 8 is fixedly provided in the stainless steel box 1. The output shaft of the control motor 8 is fixedly connected to a worm 9 that engages with the worm gear 7. That is to say, the rotation of the winding roller 2 is controlled by the cooperation of the worm 9 and the worm gear 7, and the control motor 8 provides driving force to the rotation of the worm 9, making the rotation and start and stop control of the winding roller 2 more convenient.

[0026] In this embodiment, a pad 105 is welded to the top of the stainless steel box 1 through the seat plate 13, and a solar panel 103 is arranged on the top of the pad 105. A battery 104 is arranged in the stainless steel box 1, and the battery 104 is electrically connected to the solar panel 103 and the control motor 8. By utilizing the principle of solar power generation, the battery 104 can store the electricity generated by the solar panel 103 and provide electrical energy to the control motor 8, which has the advantage of controlling the rotation of the winding roller 2 and saving energy.

[0027] In this embodiment, there are two reversing pulleys 6 and they are in the same plane. The axes of the two reversing pulleys 6 are parallel. The lower signal transmission line is reversed through the two reversing pulleys 6. This arrangement can reduce the degree of bending of the lower signal transmission line and ensure the smoothness of the lower signal transmission line when it is guided by the reversing pulley 6 for transmission.

[0028] Furthermore, a guide tube 102 is welded to the inner wall of the stainless steel box 1 through a support plate. The guide tube 102 is located below a reversing pulley 6 away from the winding roller 2. When in use, the lower signal transmission line passes through the guide tube 102. The guide tube 102 has the function of ensuring stable winding of the lower signal transmission line and the adjacent reversing pulley 6. At the same time, it also has the function of avoiding the problem of the lower signal transmission line swinging randomly. A protective rubber sleeve 1021 can be nested in the guide tube 102. The function of the protective rubber sleeve 1021 is to prevent the lower signal transmission line from being worn by the guide tube 102.

[0029] In this embodiment, a rectangular frame 12 is welded to the rear wall of the stainless steel box 1, and the two ends of the winding roller 2 are rotatably connected to the two ends inside the rectangular frame 12. In specific implementation, a positioning sleeve that is sleeved on the outside of the winding roller 2 can be welded at the two ends inside the rectangular frame 12. This setting has the effect of improving the supporting strength of the winding roller 2.

[0030] Working principle: When in use, after the pressure measuring tube 3 is installed, its bottom is extended into the groundwater layer. When it is necessary to release the piezometer into the pressure measuring tube 3, the control motor 8 is started, the winding roller 2 rotates, and the lower signal transmission line wound thereon is released. The piezometer descends in the pressure measuring tube 3. When it descends to a certain depth, the total weight of the lower signal transmission line located in the pressure measuring tube 3 increases. At this time, the start and stop of the winding roller 2 will produce a large impact traction force on the lower signal transmission line. When the impact traction force is generated, the boom 4 will move up and down under the support of the buffer spring 101 for buffering protection. That is to say, under the action of the buffer spring 101, the lower signal transmission line can be guaranteed not to be damaged while increasing the lifting speed of the piezometer.

[0031] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
