[0035] Exploration equipment 1 includes a main body 101, a drill bit 102, a water pump 103, a motor A111, and a sealing valve 113. The drill bit 102 is located at the front of the main body 101 for drilling into the ground, and the water pump 103 is located at the rear of the main body 101 for sampling groundwater. The motor A111 drives the sealing valve 113 to open and close the water inlet, preventing sediment from entering during exploration. Motor slots A104 are arranged on four sides of the main body 101. A water inlet hole 105 is opened outwards from the inside of the main body 101, and a fixing slot 106 is opened on the outside of the water inlet hole 105. Four fixing pins 107 are located on one side of the water pump 103, and pin holes are opened on the main body 101 corresponding to the fixing pins 107. The fixing pins 107 are fixedly connected to the pin holes, and the water inlet holes... A filter screen A108 is provided near the end of the water pump 103. A fixed groove 106 is fixedly connected to the filter screen B112. A motor groove A104 is fixedly connected to the motor A111.
