[0008] The flow guide rope is a corrosion-resistant flow guide rope.
[0009] Further, the drainage groove or the drainage bolt.
[0010] The drainage bolt is a funnel-shaped drainage groove opened in the bottom surface inside the guide sleeve at the middle position of the funnel-shaped bottom, and the drainage bolt is installed at the bottom of the funnel-shaped drainage groove.
[0011] The flow guide rope is in interference fit with the drainage groove.
[0012] The U-shaped drainage pad is placed at the front side opening of the guide sleeve, and the U-shaped drainage pad is downward.
[0013] The utility model has the advantages of:
[0014] 1. The utility model discloses a drainage groove is set up in the lower end surface of the guide sleeve, and the flow guide rope is installed between the guide sleeve and the bottom shell, so that the design considers the sealing performance and realizes the drainage function.
[0015] 2. The drainage structure in the narrow space considers the convenience of dismounting, and the bottom is slotted, so that the installation of the flow guide rope can be realized by the dismounting of the guide sleeve mounting bolt.
[0016] The utility model will be further described below in combination with the embodiment drawing. DRAWINGS

[0025] In order to further explain the technical means and effects taken by the utility model to achieve the predetermined purpose, the specific implementation, structural features and effects of the utility model will be described in detail as follows in combination with the drawings and embodiments.
[0026] As Figure 2 , Figure 3 and Figure 4As shown, the utility model relates to a kind of drainage structure of tight detector, it is characterized by: including guide sleeve 1 and tight detector indicating rod 7, tight detector indicating rod 7 passes through guide sleeve 1, drainage groove 3 is opened in the bottom 2 of guide sleeve 1, drainage rope 4 is embedded in the inside of drainage groove 3, drainage rope 4 is corrosion-resistant drainage rope, drainage rope 4 is clamped between the bottom end surface 5 of guide sleeve 1 and bottom shell end surface 6;When tight detector indicating rod 7 is in reciprocating process, the accumulated water in guide sleeve 1 will be discharged along drainage rope 4 by drainage groove 3.
[0027] As shown in Figure 5a Drainage groove 3 or drainage bolt 9, drainage bolt 9 is embedded in the inside of drainage rope 4, drainage rope 4 is corrosion-resistant drainage rope, drainage rope 4 is clamped between the bottom end surface 5 of guide sleeve 1 and bottom shell end surface 6;When tight detector indicating rod 7 is in reciprocating process, the accumulated water in guide sleeve 1 will be discharged along drainage rope by drainage bolt 9 inside drainage rope 4.
[0028] Further, as shown in Figure 5b Drainage groove 3 or drainage bolt 9, drainage bolt 9 is in the middle position of funnel-shaped bottom, drainage groove 3 is set in the bottom surface inside guide sleeve 1, drainage bolt 9 is installed at the bottom of funnel-shaped drainage groove 3, the difficulty of the guide sleeve 1 modification of this embodiment is greater than that of drainage rope structure, and drainage bolt 9 needs to be specially made. Drainage bolt 9 needs to be completely disassembled when installing guide sleeve 1, which is not conducive to on-site modification, so this embodiment is not preferred, but its drainage effect is better.
[0029] Because the distance between the guide sleeve 1 of the tight detector and the installation bottom plate 8 is very close, it is basically impossible to install and operate the waterproof and breathable structure. If the sealing performance of the drainage structure at guide sleeve 1 is considered, the interference fit of drainage rope 4 and drainage groove 3 needs to be designed to prevent small dust from entering the machine through drainage groove 3.
[0030] Further, when the guide sleeve 1 needs to be disassembled and repaired due to the period of time, the tight detector and the water inlet problem cannot be solved immediately, alternative embodiments such as Figure 6 As shown: a U-shaped drainage pad 10 is inserted into the front side opening of guide sleeve 1, that is, a U-shaped drainage pad 10 is placed in the front side opening of guide sleeve 1, the U-shaped drainage pad 10 is downward, the advantages of this installation are: before indicating rod 7 enters guide sleeve 1, the water on indicating rod 7 is scraped off by U-shaped drainage pad 10, and because the lower part of drainage pad 10 is in an open state, water stains will flow to the ground along the gap of drainage pad 10, playing a drainage role.
[0031] The drainage structure of the utility model, in the case of not increasing spare parts, through improving the existing guide sleeve 1, using the corrosion-resistant drainage structure such as clamping flow guide rope 4 in the small hole to drain the accumulated water in the guide sleeve 1, realizes the drainage function.
[0032] The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and the specific implementation of the utility model cannot be limited to these descriptions.
[0033] For ordinary skilled persons in the technical field to which the utility model belongs, without departing from the concept of the utility model, a number of simple deductions or substitutions can be made, and all should be regarded as belonging to the protection scope of the utility model.
