Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, and more specifically, to a continuous sampling device for water quality detection. Background Technique

[0002] Water quality monitoring is a process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality status. Generally, a sampling device is needed when sampling water bodies, which can quantitatively extract water in a targeted area to facilitate staff to quickly obtain water quality samples.

[0003] When using a sampling device to take water samples, the device needs to be moved to the water intake area. The water intake areas of some water bodies are on slopes. For the convenience of movement, universal wheels are usually installed at the bottom of the sampling device. When the sampling device is parked on a slope with a large gradient, although the universal wheels have a braking function, due to the small sliding friction between the universal wheels and the slope surface, there is still a possibility that the device will move towards the lower part of the slope. When using a water pump to pump water for sampling, the vibration generated by the operation of the water pump further increases the possibility of the device moving towards the lower part. In view of this, we propose a continuous sampling device for water quality detection. Summary of the Invention

[0004] The purpose of the utility model is to provide a continuous sampling device for water quality detection to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, one of the purposes of the utility model is to provide a continuous sampling device for water quality detection, including a bottom plate. An I-shaped frame is arranged above the bottom plate. Four extension rods are fixedly connected to the lower surface of the I-shaped frame near the four corners. Universal wheels are installed at the lower ends of the extension rods. Through grooves are opened at the four corners of the bottom plate. When moving the bottom plate, the lower ends of the extension rods penetrate through the through grooves and extend below the bottom plate. A lifting mechanism and a water intake mechanism are arranged on the bottom plate. The lifting mechanism is used to drive the I-shaped frame to move vertically. A plurality of anchoring mechanisms are arranged on the bottom plate. The anchoring mechanism includes an anchor rod. When the lifting mechanism drives the I-shaped frame to move vertically upward, the lower end of the anchor rod moves below the bottom plate.

[0006] As a further improvement of the technical solution, the anchoring mechanism further includes two vertical rods fixedly connected to the upper surface of the bottom plate. An end plate is slidably sleeved outside the two vertical rods. The upper end of the anchor rod is rotatably connected to the side wall of the end plate. A driven rack is fixedly connected to one side of the end plate. A driving rack is fixedly connected to one side of the I-shaped frame. A reversing gear is rotatably connected to the bottom plate. The driven rack and the driving rack are respectively meshed with both sides of the reversing gear.

[0007] As a further improvement of the technical solution, a rotating assembly is provided on one side of the anchor rod. The rotating assembly includes a fixed gear coaxially and fixedly connected to the outer wall of the anchor rod. An external frame is fixedly connected to one side of the end plate. A horizontal rack is slidably arranged on one side of the external frame. The horizontal rack meshes with one side of the fixed gear. One end of the horizontal rack is fixedly connected to a convex column. An inclined frame is fixedly connected to the upper surface of the bottom plate. The inclined frame is slidably sleeved on the outside of the convex column.

[0008] As a further improvement of the technical solution, the lifting mechanism includes a mounting frame fixedly connected to the upper surface of the bottom plate. A lead screw is rotatably connected to the upper side wall of the mounting frame. The I-shaped frame is threadedly connected to the lead screw. Two guide rods are fixedly connected to the upper side wall of the mounting frame. The I-shaped frame is slidably sleeved on the outside of the guide rods. A motor is fixedly connected to the upper surface of the bottom plate. Bevel gears are fixedly connected to the output shaft of the motor and the lead screw respectively. The two bevel gears mesh with each other.

[0009] As a further improvement of the technical solution, the water intake mechanism includes a water pump fixedly connected to the upper surface of the mounting frame. A water outlet pipe is fixedly connected to one side of the water pump. A water storage tank is installed at a position directly below the water outlet pipe on the upper surface of the bottom plate. A water suction pipe is fixedly connected to the other side of the water pump. An electric telescopic rod is fixedly connected to the upper surface of the bottom plate. One end of the electric telescopic rod is fixedly connected to a pulley frame. A guide wheel is rotatably connected to the top of the pulley frame. The top of the guide wheel contacts the outer wall of the water suction pipe.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] After the continuous sampling device for water quality detection is moved to the water intake location on the slope, the lifting mechanism drives the I-shaped frame to move vertically upward, so that the I-shaped frame drives the universal wheels to move above the bottom plate through the extension rods, and the bottom plate touches the ground. During this process, the I-shaped frame drives the anchor rod to move vertically downward, so that the lower end of the anchor rod is inserted into the slope soil, thereby stably placing the device on the slope and preventing the device from sliding on the slope during the water intake sampling process, improving the safety during sampling.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0022] Please refer to Figure 1 As shown, one of the purposes of this embodiment is to provide a continuous sampling device for water quality detection, including a bottom plate 1. An I-shaped frame 2 is arranged above the bottom plate 1. Four extension rods 3 are fixedly connected to the lower surface of the I-shaped frame 2 near the four corners. Universal wheels are installed at the lower ends of the extension rods 3. Through grooves 4 are opened at the four corners of the bottom plate 1. When moving the bottom plate 1, the lower ends of the extension rods 3 penetrate through the through grooves 4 and extend to the lower side of the bottom plate 1, so that the four universal wheels touch the ground, which is convenient to move the device to the water intake place. A lifting mechanism 5 is arranged on the bottom plate 1. The lifting mechanism 5 is used to drive the I-shaped frame 2 to move vertically. After moving the device to the water intake place, the lifting mechanism 5 is made to drive the I-shaped frame 2 to move vertically upward, so that the I-shaped frame 2 drives the universal wheels to move above the bottom plate 1 through the extension rods 3, and the lower surface of the bottom plate 1 touches the ground. By using the large static friction force between the bottom plate 1 and the ground, the sliding of the bottom plate 1 is prevented, and the device can be stably placed on the ground at the water intake place, solving the problem that when the water intake place is a slope, the device is prone to move towards the lower part of the slope under the action of gravity, resulting in poor stability of the device.

[0023] In order to drive the I-shaped frame 2 to move vertically, the structure of the lifting mechanism 5 is refined as follows. Refer to Figure 2, the lifting mechanism 5 includes a mounting frame 51 fixedly connected to the upper surface of the bottom plate 1. A lead screw 52 is rotatably connected to the upper side wall of the mounting frame 51. The I-shaped frame 2 is threadedly connected to the lead screw 52. Two guide rods 53 are fixedly connected to the upper side wall of the mounting frame 51. The I-shaped frame 2 is slidably sleeved outside the guide rods 53. The guide rods 53 are vertically arranged, so that the I-shaped frame 2 can only move vertically along the axis direction of the guide rods 53. A motor 54 is fixedly connected to the upper surface of the bottom plate 1. Bevel gears 55 are fixedly connected to the output shaft of the motor 54 and the lead screw 52 respectively. The two bevel gears 55 are meshed with each other. After the motor 54 is started, its output shaft drives one of the bevel gears 55 to rotate. Through the meshing transmission of the two bevel gears 55, the other bevel gear 55 drives the lead screw 52 to rotate. Through the threaded connection between the lead screw 52 and the I-shaped frame 2, the I-shaped frame 2 moves vertically under the guiding action of the guide rods 53, so that the I-shaped frame 2 can drive the four universal wheels to move vertically and adjust the relative position between the universal wheels and the bottom plate 1.

[0024] In order to further improve the stability of the device when placed on a slope, a plurality of anchoring mechanisms 7 are provided on the bottom plate 1. The anchoring mechanism 7 includes an anchor rod 73. When the lifting mechanism 5 drives the I-shaped frame 2 to move vertically upward, the lower end of the anchor rod 73 moves below the bottom plate 1, so that the anchor rod 73 can be inserted into the soft soil on the slope and play an anchoring role for the device. The following details the other structures of the anchoring mechanism 7. Refer to Figure 3 , the anchoring mechanism 7 further includes two vertical rods 71 fixedly connected to the upper surface of the bottom plate 1. An end plate 72 is slidably sleeved outside the two vertical rods 71. The vertical rods 71 are vertically arranged, so that the end plate 72 can only move vertically along the axis direction of the vertical rods 71. The upper end of the anchor rod 73 is rotatably connected to the side wall of the end plate 72. A driven rack 74 is fixedly connected to one side of the end plate 72. A driving rack 75 is fixedly connected to one side of the I-shaped frame 2. A reversing gear 76 is rotatably connected to the bottom plate 1. The driven rack 74 and the driving rack 75 are respectively meshed with both sides of the reversing gear 76. When the I-shaped frame 2 moves vertically upward, the I-shaped frame 2 drives the driving rack 75 to move upward synchronously. Through the meshing transmission between the driving rack 75 and the reversing gear 76, the reversing gear 76 rotates. Through the meshing transmission between the reversing gear 76 and the driven rack 74, the driven rack 74 drives the end plate 72 to move vertically downward, and the end plate 72 drives the anchor rod 73 to move downward synchronously. When the bottom plate 1 touches the ground, the lower end of the anchor rod 73 can be inserted into the slope soil. The sliding of the device on the slope is prevented by the anchoring of the anchor rod 73, and the stability of the device on the slope is further improved.

[0025] In order to enable the anchor rod 73 to be inserted into the slope soil more smoothly, a rotating assembly 77 is provided on one side of the anchor rod 73. Refer to Figure 4, the rotating assembly 77 includes a fixed gear 771 coaxially and fixedly connected to the outer wall of the anchor rod 73. One side of the end plate 72 is fixedly connected with an external frame 772. A horizontal rack 773 is slidably arranged on one side of the external frame 772. The horizontal rack 773 meshes with one side of the fixed gear 771. One end of the horizontal rack 773 is fixedly connected with a convex column 774. The upper surface of the bottom plate 1 is fixedly connected with an inclined frame 775. The inclined frame 775 is slidably sleeved on the outside of the convex column 774. The surface of the inner wall of the inclined frame 775 in contact with the convex column 774 is inclined. When the end plate 72 drives the anchor rod 73 to move vertically downward, the end plate 72 drives the external frame 772 to move downward synchronously. The external frame 772 drives the horizontal rack 773 to move downward synchronously. When the horizontal rack 773 drives the convex column 774 to move downward, the convex column 774 slides along the inclined surface of the inner wall of the inclined frame 775, so that the convex column 774 drives the horizontal rack 773 to move horizontally relative to the external frame 772. Through the meshing transmission between the horizontal rack 773 and the fixed gear 771, the fixed gear 771 drives the anchor rod 73 to rotate. Thus, during the vertical downward movement of the anchor rod 73, the anchor rod 73 rotates synchronously, enabling the anchor rod 73 to be inserted more smoothly into the slope soil, playing the anchoring role of the anchor rod 73 on the device, and further improving the stability of the device placed on the slope.

[0026] A water intake mechanism 6 is arranged on the upper surface of the bottom plate 1. After the device is stably placed at the water intake location, the water intake mechanism 6 can take water samples from the water source. The structure of the water intake mechanism 6 is refined as follows. The water intake mechanism 6 includes a water pump 61 fixedly connected to the upper surface of the mounting frame 51. One side of the water pump 61 is fixedly connected with a water outlet pipe 62. A water storage tank 63 is installed at a position on the upper surface of the bottom plate 1 directly below the water outlet pipe 62. The other side of the water pump 61 is fixedly connected with a water suction pipe 64. The upper surface of the bottom plate 1 is fixedly connected with an electric telescopic rod 65. One end of the electric telescopic rod 65 is fixedly connected with a pulley frame 66. A guide wheel is rotatably connected to the top of the pulley frame 66. The top of the guide wheel is in contact with the outer wall of the water suction pipe 64. When the electric telescopic rod 65 extends, it drives the pulley frame 66 to move away from the bottom plate 1, so that the pulley frame 66 drives one end of the water suction pipe 64 to move away from the bottom plate 1. Until one end of the water suction pipe 64 sinks into the water source, the water pump 61 is started. The water pump 61 pumps out a part of the water body in the water source through the water suction pipe 64, and then discharges this part of the water body into the interior of the water storage tank 63 through the water outlet pipe 62, completing the water intake sampling of the water source. During the water intake sampling process, the device will not slide on the slope, improving the safety during sampling.
