Description

Technical Field

[0001] The invention relates to the technical field of saline soil preparation, and in particular to a saline soil preparation device. Background Art

[0002] Compared with onshore wind power, offshore wind power has 20% to 40% higher energy efficiency than onshore wind farms. It also has the advantages of no land occupation, high wind speed, less sand and dust, large power, stable operation and zero dust emission. At the same time, it can reduce the wear of the unit and extend the service life of the wind turbine, which is suitable for large-scale development. The seabed foundation soil where the offshore wind turbine foundation is installed is saline soil containing a variety of electrolytes. The salinity of water and soil affects the corrosiveness, conductivity and structural strength characteristics of marine soil.

[0003] In order to carry out research on the physical and mechanical properties of saline soil, it is necessary to prepare saline soil in batches indoors. In the prior art, the production of saline soil usually involves placing granular soil, various salts, water and other preparation materials in a container in a certain proportion, mixing and stirring, and allowing the saline soil preparation materials to stand for a long time after sufficient stirring to allow water and soil to separate. After a long period of standing, the saline soil at the bottom of the container is solidified and formed, so that the staff can study the physical and mechanical properties of saline soil and simulate the structural strength of marine soil. However, in the process of making saline soil, since the saline soil preparation materials in the container are in contact with the outside world for a long time, the saline soil preparation materials will lose water, the salinity will change, or external substances will enter the saline soil preparation materials, resulting in the saline soil being unable to simulate the structural strength of marine soil.

[0046] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] Combine the following Figures 1 to 6The saline soil preparation device of the present invention includes: a constant temperature box 1 and a soil preparation box 11. A box door 2 is opened and closed on one side of the constant temperature box 1. A constant temperature chamber is left in the constant temperature box 1. The soil preparation box 11 is suitable for being placed inside the constant temperature chamber. A placement chamber is provided in the soil preparation box 11. The placement chamber is suitable for placing saline soil preparation materials. A temperature control mechanism is provided in the constant temperature chamber for controlling the temperature inside the constant temperature box 1. A salinity measuring mechanism 8 is also provided in the constant temperature box 1. The salinity measuring mechanism 8 is used to contact the saline soil preparation materials. A water replenishing mechanism is also provided in the constant temperature chamber, and the water replenishing mechanism is connected to the placement chamber. The saline soil preparation device also includes a controller 5. The controller 5 is electrically connected to the temperature control mechanism for adjusting the temperature of the constant temperature chamber according to the preset temperature of the controller 5; the controller 5 is also electrically connected to the salinity measuring mechanism 8 for feeding back the salinity of the saline soil preparation materials to the controller 5; the controller 5 is also electrically connected to the water replenishing mechanism, and the controller 5 controls the water replenishing mechanism to inject water into the placement chamber according to the salinity of the saline soil preparation materials.

[0048] This saline soil preparation device can effectively prevent foreign substances from entering the saline soil preparation material by placing the soil preparation box 11 in the constant temperature chamber to prepare saline soil, thereby preventing foreign substances from contaminating the saline soil preparation material. By presetting a preset temperature in the controller 5, when the temperature inside the constant temperature chamber is lower than the preset temperature, the controller 5 sends a signal to the temperature control mechanism, and the temperature control mechanism adjusts the temperature inside the constant temperature chamber. When the temperature inside the constant temperature chamber reaches the preset temperature, the temperature control mechanism is closed to ensure that the temperature inside the constant temperature chamber is constant, so as to ensure that the salt in the saline soil preparation material is dissolved in a stable environment.

[0049] In this embodiment, the controller 5 controls the salinity measuring mechanism 8 to measure the salinity in the saline soil preparation material in real time and feeds the salinity back to the controller 5. The controller 5 controls the water replenishment mechanism to inject water into the placement cavity according to the salinity of the saline soil preparation material, so as to ensure the stability of the salinity of the saline soil preparation material in the placement cavity. At the same time, the controller 5 controls the water replenishment mechanism to inject water into the placement cavity, so as to replenish the evaporated water in the saline soil preparation material and maintain the salinity of the saline soil preparation material. That is, the controller 5 controls the temperature control mechanism, the salinity measuring mechanism 8 and the water replenishment mechanism, so that the constant temperature cavity is in a constant temperature environment, so as to ensure that the saline soil preparation material is always consolidated into soil in a stable environment, avoid the salinity change of the saline preparation material caused by water loss and temperature change, realize the preparation of standard saline soil with stable salinity, and ensure that the prepared saline soil can effectively simulate the structural strength of marine soil.

[0050] Specifically, Figure 6As shown, the salinity measuring mechanism 8 includes a driving member 802 and a moving part. The driving member 802 is connected to the moving part. The driving member 802 can be a motor or other driving member 802. The moving part can be a gear 803, a transmission belt and a chain, etc., which are not specifically limited here. A salinometer 806 is provided on the moving part, and the salinometer 806 is used to contact the saline soil preparation material. The driving member 802 and the salinity member are electrically connected to the controller 5 respectively, and the controller 5 is used to control the driving member 802 to drive the moving part to move along the height direction of the soil making box 11. When the water in the saline soil preparation material in the placement cavity evaporates and causes the liquid level inside the placement cavity to drop, the driving member 802 is controlled by the controller 5 to drive the moving part to move along the height direction of the soil making box 11, so that the salinometer 806 is always in contact with the saline soil preparation material, and the salinity in the saline soil preparation material is detected and fed back. At the same time, the position of the salinometer 806 is adjusted by the controller 5, so that the salinometer 806 can be in contact with saline soil preparation materials of different experimental doses. For example, during the first experiment, more saline soil preparation materials are placed in the placement cavity. At this time, the liquid level in the placement cavity will be relatively high, and the salinometer 806 should also be adjusted to a corresponding height to contact the saline soil preparation materials; when the first experiment is completed, when the second experiment is carried out, less saline soil preparation materials are placed in the placement cavity. At this time, the liquid level in the placement cavity is also relatively low. At this time, the salinometer 806 can be adjusted downward to a corresponding height to contact the salt preparation.

The water level in the saline soil preparation material is detected by the water level measuring member 805 and the data can be fed back to the controller 5 in real time. During the experiment, as the saline soil preparation material in the placement cavity is deposited, the separation height of water and soil will also change. The water level measuring member 805 is used to detect the change of the separation height of water and soil and feed it back to the controller 5. For example, a reflective sheet is placed in the saline soil preparation material corresponding to the water level measuring member 805, and the reflective sheet is located on the water and soil separation surface, that is, the reflective sheet is placed on the soil plane, and the separation height of water and soil is detected by measuring the distance between the water level measuring member 805 and the soil. Among them, the water level measuring member 805 can be a laser sensor.

The current direction of the coil 703 on the surface of the fixed magnet 702 is adjusted by the controller 5 to realize the change of the magnetic pole of the fixed magnet 702. The magnetic pole change of the fixed magnet 702 is controlled by the controller 5 to realize the sliding of the moving magnet 706 in the guide sleeve 705, so that the moving magnet 706 can switch between the closed state of closing the blocking hole and the open state of opening the blocking hole, so as to control the opening and closing of the opening and closing mechanism 7.

Setting the heating element 9 on the inner wall of the thermostatic box 1 effectively improves the heating efficiency of the thermostatic chamber, and is also beneficial to improving the space utilization rate of the thermostatic chamber.

[0058] Specifically, Figure 2 and Figure 3 As shown, a support plate 10 is also provided in the constant temperature chamber, and a plurality of through holes are arranged at intervals on the support plate 10. The support plate 10 is horizontally arranged at the bottom of the constant temperature chamber, and the heating element 9 near the bottom of the constant temperature chamber is located between the support plate 10 and the bottom plate of the constant temperature box 1. The soil making box 11 is suitable for being placed on the support plate 10. By arranging the soil making box 11 on the support plate 10, the soil making box 11 is prevented from crushing the heating element 9 at the bottom of the constant temperature. By arranging a plurality of through holes on the support plate 10, the hot air flow can be effectively circulated, thereby quickly raising the internal temperature of the constant temperature box 1. Among them, the bottom of the soil making box 11 can be provided with box legs, and the soil making box 11 can be moved to the support plate 10 by a forklift.

[0059] Specifically, the door 2 is rotatably arranged on one side of the thermostatic box 1 through a door shaft 3. A handle 201 can be arranged on the door 2 to facilitate opening and closing the door 2. A lock body 202 that cooperates with the thermostatic box 1 can also be arranged on the door 2.

[0060] The working principle of the salt-containing soil preparation device in this embodiment is:

[0061] The saline soil preparation material with a good proportion is placed in the placement cavity of the soil making box 11, and the soil making box 11 is moved to the support plate 10 of the constant temperature cavity by a forklift, and the salinity measuring mechanism 8 and the water replenishing mechanism are adjusted so that the salinity meter 806 in the salinity measuring mechanism 8 is in contact with the saline soil preparation material. By presetting the preset temperature in the controller 5, when the temperature inside the constant temperature cavity is lower than the preset temperature, the controller 5 sends a signal to the temperature control mechanism, and the temperature control mechanism adjusts the temperature inside the constant temperature cavity. When the temperature inside the constant temperature cavity reaches the preset temperature, the temperature control mechanism is closed to ensure that the temperature inside the constant temperature cavity is constant, so as to ensure that the salt in the saline soil preparation material is dissolved in a stable environment. By controlling the salinity measuring mechanism 8 through the controller 5, the salinity in the saline soil preparation material can be measured in real time and the salinity can be fed back to the controller 5. The controller 5 controls the water replenishment mechanism to inject water into the placement cavity according to the salinity of the saline soil preparation material, so as to ensure the stability of the salinity of the saline soil preparation material in the placement cavity. At the same time, by controlling the water replenishment mechanism to inject water into the placement cavity through the controller 5, the evaporated water in the saline soil preparation material can be replenished to maintain the salinity of the saline soil preparation material. In the preparation process, the soil in the saline soil preparation material is converted into saline soil due to its own weight. In the consolidation process, the temperature inside the constant temperature cavity, the salinity of the saline soil preparation material and the water content of the saline soil preparation material are maintained stable according to the controller 5 until the consolidation is completed into soil, so as to avoid the salinity change of the saline preparation material caused by water loss and temperature change, so as to realize the preparation of standard saline soil with stable salinity, and ensure that the prepared saline soil can simulate the structural strength of marine soil.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
