Description

Technical Field

[0001] The utility model belongs to the technical field of water level detection, and in particular relates to a pressure-bearing water level detector. Background Art

[0002] The pressurized water level detector is a device that uses water pressure to detect water level height. When in use, the detection head will be placed at the bottom of the water. The higher the water level, the greater the water pressure, and then the water level detection work will be realized. It is mostly used for deeper underground water level detection in rivers, wells, etc. It mainly includes a water pressure detection head, signal connection line, and controller.

[0003] When using the existing water level detector, the pressure detection head is placed on the bottom of the water. Different water level heights require signal lines of different lengths, so the supporting signal lines are relatively long. This results in nowhere to put the excess signal lines when performing shallow water level detection, which is prone to tangling and confusion. At the same time, when detecting rivers or wells, the silt at the bottom of the river will cause the detection head to enter the silt, which will not only affect the detection results, but also cause clogging of the detection head.

DETAILED DESCRIPTION

[0018] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0019] Please refer to Figure 1-Figure 2 As shown, a pressure-bearing water level detector includes a U-shaped base 1, a controller 4 and a protective cover 8. A turntable 2 is rotatably installed on the lower surface of the inner part of the U-shaped base 1, and a winding column 21 is vertically arranged at the top center of the turntable 2. A connecting signal line 3 is wound on the surface of the winding column 21 to ensure the order of the connecting signal line 3 and prevent the longer connecting signal line 3 from being tangled and disordered. A signal docking joint 22 is arranged at one end of the connecting signal line 3, and the signal docking joint 22 passes through the upper surface of the winding column 21. The controller 4 is placed on the inner side of the U-shaped base 1, and a signal docking hole corresponding to the signal docking joint 22 is arranged at the bottom of the controller 4. When the controller 4 is installed in place, the signal docking is realized to ensure that the pressure information of the low-pressure detection head 7 can be transmitted to the controller 4. A pressure detection head 7 is arranged at the end of the connecting signal line 3 away from the signal docking joint 22, and detection holes 71 are symmetrically opened below the surface of the pressure detection head 7. During detection, the pressure detection head 7 is placed on the bottom of the water, and the water level is judged by detecting the change in pressure.

[0020] Please refer to Figure 3 As shown, the protective sleeve 8 is installed on the surface of the pressure detection head 7, and an embedded cone head 84 is provided at the bottom of the protective sleeve 8. When the pressure detection head 7 is placed vertically on the bottom of the water, it can be inserted into the silt through the conical embedded cone head 84 to keep the pressure detection head 7 in a vertical state. When falling, the embedded cone head 84 has a large dead weight to ensure vertical falling. An inner concave surface 85 is provided on the surface of the protective sleeve 8, and through holes 86 are symmetrically provided on the inner side of the inner concave surface 85. The through holes 86 correspond to the positions of the detection holes 71. When the through holes 86 are exposed, external water flow will enter, and then the detection work will be realized. A protective net 87 is provided on the inner side of the through hole 86 to prevent the entry of foreign matter. A sliding sleeve 88 is vertically slidably installed on the inner concave surface 85. When the sliding sleeve 88 is placed at the bottom, the through hole 86 can be sealed.

[0021] Among them, a connecting rod 810 is provided at the bottom of the sliding sleeve 88, and a baffle 811 extends outward from the bottom of the connecting rod 810. The baffle 811 is an integral structure with the sliding sleeve 88. When falling vertically, the baffle 811 will be hindered by the silt to drive the sliding sleeve 88 to move upward, so that the through hole 86 is exposed. Slide grooves 89 are symmetrically opened below the outer surface of the protective sleeve 8. The two slide grooves 89 and the two through holes 86 are staggered at 90° respectively. The bottom of the connecting rod 810 slides on the inside of the slide groove 89 to ensure that the sliding sleeve 88 and the baffle 811 can only slide along the track of the slide groove 89.

[0022] Please refer to Figure 3 As shown, a guiding cone 812 is provided at the bottom of the baffle 811 to guide the water flow when falling vertically, thereby ensuring that the pressure detection head 7 is in a vertical state when falling.

[0023] Please refer to Figure 3 As shown, notch grooves 81 are symmetrically provided on both sides of the top of the protective sleeve 8, and extension plates 82 are symmetrically provided on both sides of the top of the protective sleeve 8. The two extension plates 82 in the same group are respectively placed on both sides of the notch groove 81, and a locking bolt 83 is screwed between the two extension plates 82 in the same group to facilitate the installation of the protective sleeve 8 and the pressure detection head 7. It can be flexibly adjusted according to actual use conditions. The protective sleeve 8 can be removed when there is no silt on the detection target or vertical laying cannot be performed.

[0024] Please refer to Figure 2 As shown, limiting top plates 23 are symmetrically arranged on both sides of the top of the winding column 21, and the bottom of the controller 4 is in contact with the upper surfaces of the two limiting top plates 23. The limiting top plates 23 can limit the connection signal line 3 and increase the support for the controller 4 at the same time.

[0025] A positioning tube 5 is provided at the front side of the U-shaped base 1 , and the connecting signal line 3 passes through the positioning tube 5 , and is positioned when the connecting signal line 3 is retracted or released. A locking bolt 6 is vertically screwed on the top of the positioning tube 5 .

[0026] The working principle of the utility model is as follows: first, the U-shaped base 1 is placed horizontally, and then the protective cover 8 is installed on the surface of the pressure detection head 7 to ensure that the positions of the through hole 86 and the detection hole 71 correspond to each other. At this time, due to the deadweight of the sliding sleeve 88, the sliding sleeve 88 is placed at the bottom of the inner concave surface 85 without being subjected to pressure to close the through hole 86, and the connecting signal line 3 is pulled out, the pressure detection head 7 is placed vertically on the bottom of the water, and then the controller 4 is placed on the top of the winding column 21, so that the signal docking head 22 docks with the docking hole at the bottom of the controller 4 to ensure the transmission of the signal. When the pressure detection head 7 reaches the bottom of the water, the conical surface of the buried cone head 84 is used to insert it into the silt to maintain its position. At the same time, during the insertion into the silt, the silt can push the baffle 811 to drive the sliding sleeve 88 to move upward inside the inner concave surface 85, thereby exposing the through hole 86 to realize the detection work, and the guiding cone surface 812 can ensure the guidance of water resistance during the falling process to keep the pressure detection head 7 falling vertically.

[0027] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
