[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, a soil temperature, humidity, and salinity sensor is disclosed, comprising a housing 1, with a bottom cavity 101 and a top cavity 102 at the bottom and top of the housing 1, respectively, and the top of the top cavity 102 being an open design. A sensor body 2 is disposed inside the bottom cavity 101. A through hole 103 is provided between the bottom cavity 101 and the top cavity 102, through which the data cable of the sensor body 2 passes and is located inside the top cavity 102. A top cover 3 is fitted onto the top surface of the housing 1. A fixing component 4 for fixing the top cover 3 is provided on the side wall of the top cavity 102. A strip-shaped opening 104 is provided on the side wall of the bottom cavity 101. A screw 5 is fixed on the side of the sensor body 2 near the strip-shaped opening 104. The screw 5 passes through the strip-shaped opening 104 and is slidably connected to the strip-shaped opening 104. Three through holes 7 for the probe of the sensor body 2 to pass through are provided at the bottom of the housing 1. Side support components 9 are provided on both sides of the outer side wall of the housing 1.

[0022] The screw 5 passes through the surface of one end of the slot 104 and is rotatably connected to the nut 6, which is in contact with the surface of the outer shell 1.

[0023] The sensor body 2 can slide along the bottom cavity 101, allowing the probe at the bottom of the sensor body 2 to pass through the through hole 7 and be inserted into the soil. If it is necessary to move the sensor body 2, the sensor body 2 can be moved inside the bottom cavity 101 by moving the screw 5 outside the outer shell 1. The strip-shaped opening 104 can guide the screw 5. After moving the screw 5 and the sensor body 2, the nut 6 can be tightened so that the nut 6 fits tightly against the outer wall of the outer shell 1, and the screw 5 is fixed by friction, thereby fixing the sensor body 2.

[0024] A rubber ring 8 is fixed to the inner wall of the through hole 7.

[0025] When the probe of the sensor body 2 is pulled out of the soil, the probe surface will have soil. By setting the rubber ring 8 in close contact with the probe surface, the rubber ring 8 can scrape off the soil on the surface of the probe when the probe is retracted into the bottom cavity 101, ensuring the cleanliness of the probe.

[0026] The fixing assembly 4 includes a protrusion 41 fixed to the inner side wall of the top cavity 102, the protrusion 41 and the side wall of the top cavity 102 together form a groove 42, the inner side wall of the groove 42 is fixed with a spring 43, and the other end of the spring 43 is fixedly connected with a clamping tooth 44, and the side wall of the top cover 3 is provided with a clamping hole 31 for clamping the clamping tooth 44.

[0027] When the top cover 3 is fixed, the two clamping teeth 44 of the fixing assembly 4 are first squeezed so that the clamping teeth 44 retract into the groove 42, and then the top cover 3 is sleeved on the top of the shell 1. When the bottom of the top cover 3 contacts the clamping tooth 44, the clamping tooth 44 is loosened, and as the top cover 3 continues to be sleeved on the surface of the shell 1, the clamping tooth 44 is aligned with the clamping hole 31. At this time, the spring 43 squeezes the clamping tooth 44 to clamp into the clamping hole 31, thereby achieving the fixation of the top cover 3. When disassembling the top cover 3, the clamping tooth 44 is first squeezed to disengage from the clamping hole 31, and then the top cover 3 can be pulled off from the top of the shell 1.

[0028] The side support assembly 9 includes a U-shaped seat 91 fixed to the bottom end of the outer side wall of the shell 1, and a support rod 92 rotatably connected inside the U-shaped seat 91. The end of the support rod 92 away from the U-shaped seat 91 is designed as a sharp head.

[0029] When the support rod 92 is not in use, it is rotated to be in close contact with the shell 1. When in use, the support rod 92 is rotated downward, and the sharp head of the support rod 92 is inserted into the soil. The positions of the two support rods 92 and the three probes inserted into the soil form a cross, which can further improve the stability of the entire sensor.

[0030] A magnet is fixed to the surface of the shell 1 near the support rod 92, and the support rod 92 is made of iron. When the support rod 92 is in close contact with the shell 1, it can be fixed by the magnet.

[0031] Working principle: First, squeeze the clamping tooth 44 to disassemble the top cover 3, then take out the data line from the top cavity 102 and connect it with the equipment, then loosen the nut 6 and move the screw rod 5 downward, so that the probes at the bottom of the sensor body 2 move out of the through hole 7, and then tighten the nut 6 to fix the screw rod 5 and the sensor body 2. Then rotate the two support rods 92 downward, and make the support rods 92 maintain a certain angle with the shell 1, then insert the three probes and the two support rods 92 into the soil at the same time. After use, loosen the nut 6 and move the screw rod 5, so that the probes retract into the bottom cavity 101, then store the data line in the top cavity 102, and finally cover the top cover 3.

[0032] The preferred embodiments disclosed above are only used to help illustrate the present application. The preferred embodiments do not have the details described in detail, and are not limited to the specific implementation of the present application. Obviously, according to the content of the specification, many modifications and changes can be made. The present application selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present application, so that those skilled in the art can well understand and utilize the present application. The present application is limited by the claims and their entire scope and equivalents.
