Detailed Embodiments

[0023] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "front", "upper", "lower", "left", "right", "vertical", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0024] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0025] The following further describes the present utility model in conjunction with the Figures 1-4 accompanying drawings.

[0026] To solve the problems existing in the background art, the present application proposes the following technical solution: It includes a detection rod 1. A pointed head 4 is fixedly connected to the bottom end of the detection rod 1. Both the detection rod 1 and the handle 2 are made of metal. The setting of the pointed head 4 facilitates the insertion of the detection rod 1 into the sand and dust or the soil after greening. When the pointed head 4 touches the manhole cover, the position of the well chamber can be determined, thereby achieving the purpose of conveniently finding the well chamber and improving the work efficiency of maintenance personnel.

[0027] A limiting block 6 is fixedly installed on the outer surface of the detection rod 1. The limiting block 6 is composed of a vertical surface and an inclined surface. A positioning ring plate 7 is movably sleeved outside the detection rod 1. An installation cavity 8 is opened inside the positioning ring plate 7. A notch 9 is opened on one side of the installation cavity 8 close to the detection rod 1. An extrusion block 10 is slidably installed in the installation cavity 8. One side of the extrusion block 10 close to the detection rod 1 is provided as a slope 15, and the slope 15 is adapted to the inclined surface of the limiting block 6.

[0028] When the detection rod 1 is inserted downward into the soil to detect the manhole cover, due to the obstruction of the soil to the positioning ring plate 7 and the contact between the slope 15 of the extrusion block 10 and the inclined surface of the limit block 6, the limit block 6 will not obstruct the movement of the notch 9. As the detection rod 1 is inserted, the positioning ring plate 7 moves upward on the detection rod 1. When the pointed head 4 touches the manhole cover, the distance from the bottom of the positioning ring plate 7 to the top of the pointed head 4 is the depth of the manhole cover in the soil. When the detection rod 1 is lifted from the soil, due to the vertical surface of the limit block 6 restricting the bottom of the extrusion block 10, preventing the positioning ring plate 7 from moving downward, the positioning ring plate 7 can only move upward on the detection rod 1 and cannot move downward without external force. The depth of the manhole cover is marked by the positioning ring plate 7, which is convenient for maintenance personnel to locate the depth of the well chamber under dust and greening, improving the practicability of the detection device.

[0029] Furthermore, a return spring 14 is arranged inside the installation cavity 8. One end of the return spring 14 is fixedly connected to the end of the extrusion block 10 away from the detection rod 1, and the other end of the return spring 14 is fixedly installed at the bottom of the installation cavity 8.

[0030] When the positioning ring plate 7 moves upward on the detection rod 1, the contact between the inclined surface of the limit block 6 and the slope of the extrusion block 10 will drive the extrusion block 10 to move away from the detection rod 1. The extrusion block 10 compresses the return spring 14. The compressed return spring 14 will push the extrusion block 10 in the opposite direction to restore its initial state, causing the extrusion block 10 to move towards the detection rod 1. The setting of the extrusion block 10 keeps the extrusion block 10 in contact with the limit block 6 at all times, ensuring the restrictive effect of the vertical surface of the limit block 6 on the extrusion block 10 and improving the stability of the device during use.

[0031] Furthermore, a telescopic rod 13 is fixedly installed at the bottom of the installation cavity 8. One end of the telescopic rod 13 is fixedly connected to one side of the extrusion block 10, and the return spring 14 is sleeved outside the telescopic rod 13.

[0032] The setting of the telescopic rod 13 plays a guiding and restrictive role for the return spring 14, avoiding the deviation of the return spring 14 during the compression or restoration process and improving the stability of the return spring 14 during use.

[0033] Furthermore, a sliding groove 11 is opened at the upper end of the positioning ring plate 7. The sliding groove 11 is communicated with the installation cavity 8. A dial plate 12 is slidably installed in the positioning ring plate 7, and the bottom end of the dial plate 12 is fixedly connected to the upper surface of the extrusion block 10.

[0034] The sliding groove 11 and the dial plate 12 cooperate to guide and limit the movement of the extrusion block 10, improving the stability of the extrusion block 10 when moving in the installation cavity 8. Push the dial plate 12 to move away from the detection rod 1. The dial plate 12 drives the extrusion block 10 to move, so that the bottom surface of the extrusion block 10 no longer contacts the vertical surface of the limit block 6, and the limit block 6 no longer restricts the movement of the positioning ring plate 7. The positioning ring plate 7 can move freely up and down on the surface of the detection rod 1. Move the positioning ring plate 7 to the bottom of the detection rod 1 for convenient next detection, improving the convenience of using the device.

[0035] Furthermore, a handle 2 is fixedly installed at the top of the detection rod 1, and a groove 3 is opened at the bottom end of the handle 2.

[0036] Press the detection rod 1 downward through the handle 2 to insert it into the soil. The groove 3 fits with the human finger, improving the stability when the human hand grips the handle 2 to exert force, thereby improving the practicality of the device.

[0037] Furthermore, scale lines 5 are provided on the circumferential surface of the detection rod 1. When the tip 4 touches the manhole cover, the scale line 5 at the bottom position of the positioning ring plate 7 is the depth of the manhole cover in the soil. The setting of the scale lines 5 can directly obtain the depth of the manhole cover in the soil, improving the convenience of using the device.

[0038] The specific operation and use are as follows: First, push the dial plate 12 to move away from the detection rod 1. The dial plate 12 drives the extrusion block 10 to move, so that the bottom surface of the extrusion block 10 no longer contacts the vertical surface of the limit block 6. Move the positioning ring plate 7 to the bottom of the detection rod 1. Place the detection rod 1 vertically on the soil. Press the detection rod 1 downward through the handle 2 to insert it into the soil. As the detection rod 1 is inserted, the positioning ring plate 7 moves upward on the detection rod 1. After the tip 4 touches the manhole cover, pull out the detection rod 1. The scale line 5 at the bottom position of the positioning ring plate 7 is the depth of the manhole cover in the soil, completing the detection of the position and depth of the well chamber.

The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding in the existing technology.
